[0001] [0001] The present invention relates to a vehicle body front section structure. TECHNICAL BACKGROUND
[0002] [0002] Structures are known in which a coupler member is fixed to a front end portion of the skirt reinforcement, and a face portion attached to a front end of the coupler member is interposed between a front side frame and a can of collision, and attached to them (for example, see the Patent Application Open to Public Inspection (JP-A) in JP 2005-231435). SUMMARY OF THE INVENTION TECHNIQUE PROBLEM
[0003] [0003] In the above configuration, a load transmission path is formed to transmit load input to the face portion through the coupler member to the skirt reinforcement in a small overlap collision. However, configurations where the load is simply transmitted towards the rear of the vehicle leave room for improvement from the perspective of suppressing a cabin deformation in a small overlap collision.
[0004] [0004] An object of the present invention is to obtain a vehicle body front section structure capable of suppressing the deformation of a vehicle body in a small overlap collision. SOLUTION TO THE PROBLEM
[0005] [0005] A vehicle body front section structure according to a first aspect of the present invention includes: a front side member, with a crash box attached to a front side in the vehicle longitudinal direction; a coupler member which is interposed between and adjacent to the crash box and the front side member on a front side in the longitudinal direction of the vehicle and which is adjacent to a fender skirt section on a rear side in the longitudinal direction of vehicle; and a spacer which is disposed overlying the front side member and the coupler member in a vertical vehicle direction in a portion positioned between the front side member and the coupler member in plan view.
[0006] [0006] According to the above aspect, the collision load is inserted into the coupler member, for example, in a frontal collision mode in which the load is inserted in the vehicle width direction outside the frontal side limb (referred to later as "small overlapping collision"). When the coupler member undergoes deformation or displacement under this load, a front end portion of the front side member is pulled towards the outer vehicle width direction, as a front end side of the coupler member is interposed. between the collision box and the front side member, and next to them. Furthermore, the front side member is pushed towards the vehicle width direction in the interior by the spacer positioned between the coupler member and the front side member which accompanies the deformation or displacement of the coupler member described above. The front side member therefore bends and the vehicle and the collision counterpart thereof are shifted in the vehicle width direction, thereby suppressing the collision duplicate from penetrating the vehicle body of the vehicle.
[0007] [0007] The vehicle body front section structure of the above aspect can consequently suppress the vehicle body deformation in a small overlap collision.
[0008] [0008] In the above aspect, a configuration can be elaborated in which the spacer is provided in a vehicle width direction outside the vehicle portion of the front side member.
[0009] [0009] In accordance with the above aspect, the spacer is provided to the front side member so that a specific location of the front side member (the installation location) is pushed towards the interior vehicle width direction by the spacer in a small overlap collision. The front side member can consequently be bent into an appropriate location in a small overlap collision.
[0010] [0010] In the above aspect, the configuration can be elaborated in which the coupler member includes a horizontal portion that extends along the length direction of the front side member from a portion interposed between the collision box and the front side member towards the rear in the vehicle longitudinal direction, as seen from the side, so that it overlaps the front side member and spacer in the vehicle vertical direction.
[0011] [0011] According to the above aspect, the horizontal portion of the coupler member extends from the portion of the coupler member interposed between the collision box and the front side member towards the rear, namely, substantially horizontally. The spacer transmits the load from the horizontal portion as a force to push the front side member towards the interior vehicle width direction. Since the horizontal portion extends substantially in the horizontal direction, as described above, when the collision load is transmitted to the spacer, namely, to the front side member, a component force is suppressed from rising in the direction. vertical position of vehicle. In this way, this enables the collision load to be efficiently transmitted to the front side member.
[0012] [0012] In the above aspect, a configuration can be elaborated in which the coupler member is configured to include a main body.
[0013] [0013] According to the above aspect, the opposite face portion that forms a shoulder in the vehicle vertical direction relative to the main body on the junction plate opposes the spacer thereby enabling the load to be transmitted through from the spacer to the front side member through a wider reach in the vertical vehicle direction. Namely, the collision load can be efficiently transmitted to the front side member.
[0014] [0014] In the above aspect, a configuration can be elaborated in which: the coupler member is configured to include a main body that extends from the fender skirt section towards a front side in the vehicle longitudinal direction portion of the front side member, and a joint plate which is joined to a front side in the vehicle longitudinal direction of the main body and is interposed between the crash box and the front side member, and joined thereto; wherein a horizontal portion, which extends along the length direction of the front side member from a portion interposed between the collision box and the front side member towards the rear in the longitudinal direction of the vehicle as observed by the side so that it overlaps the front side member and the spacer in the vehicle vertical direction, is configured to include a front side in the vehicle longitudinal direction portion of the main body; an opposite face portion is formed at a location of the joint plate that is joined to the main body so that the opposite face portion forms a shoulder in the vehicle vertical direction relative to the main body and opposes the spacer to the the same time that it overlaps the spacer in the vehicle's vertical direction; and the joint plate includes a pair of plate portions which sandwich the horizontal portion, and the pair of plate portions is respectively joined to the horizontal portion by arc welding.
[0015] [0015] According to the above aspect, the pair of plate portions that sandwich the horizontal portion of the main body are respectively joined to the horizontal portion by arc welding, thus firmly joining the junction plate and the main body each other. Consequently, the action of the coupler member to pull the front end side of the front side member towards the outer vehicle width direction is efficiently displayed in a small overlap collision.
[0016] [0016] In the above aspect, a configuration can be devised in which the spacer protrudes outward to the vehicle width direction on the outside of the front side member and which additionally includes a support member that supports the rear spacer in the vehicle longitudinal direction as the spacer undergoes displacement and deformation towards the rear in the vehicle longitudinal direction along the coupler member when the load towards the rear in the vehicle longitudinal direction acts on the spacer a from the coupler member.
[0017] [0017] According to the above aspect, due to the provision of the support member, the spacer is supported from the rear of the vehicle by the support member when the coupler member undergoes deformation or displacement and pushes the front side member through the spacer.
[0018] [0018] A vehicle body front section structure in accordance with an aspect of the present invention includes a front side member, with a crash box attached to a front side in the vehicle longitudinal direction; a coupler member which is interposed between the collision box and the front side member, and together with them, on a front side in the vehicle longitudinal direction and which is adjacent to a fender skirt section on a rear side in the longitudinal direction of the vehicle; a spacer that projects outwardly in the vehicle width direction outside the front side member and which is provided to the front side member so that it overlaps a portion of the coupler member, and the front side member, in the direction vehicle vertical; and a support member which supports the spacer from the rear in the vehicle longitudinal direction as the spacer undergoes displacement or deformation towards the rear in the vehicle longitudinal direction with the coupler member when the load towards the rear in the longitudinal direction of the vehicle, it acts on the spacer from the coupling member.
[0019] [0019] According to the above aspect, the collision load is inserted into the coupler member, for example, in a frontal collision mode in which the load is inserted in the vehicle width direction outside the frontal side limb (referred to later as "small overlapping collision"). When the coupler member undergoes deformation or displacement under this load, a front end portion of the front side member is pulled towards the outer vehicle width direction, as a front end side of the coupler member is interposed. between the collision box and the front side member, and next to them. Furthermore, the front side member is pushed towards the vehicle width direction in the interior by the spacer positioned between the coupler member and the front side member which accompanies the deformation or displacement of the coupler member described above. The front side member bends accordingly, and the vehicle and the collision duplicate thereof are shifted in the vehicle width direction, thereby suppressing the collision duplicate from penetrating the vehicle body of the vehicle.
[0020] [0020] The vehicle body front section structure of the above aspect can consequently suppress the deformation of the vehicle body in a small overlap collision. Furthermore, due to the provision of the support member, the spacer is supported by the vehicle rear support member when the coupler member undergoes deformation or displacement and pushes the front side member through the spacer.
[0021] [0021] In the above aspect, a configuration can be elaborated in which the support member is configured to include a projecting portion that projects outwardly from the coupler member towards a rear in the vehicle longitudinal direction of the spacer portion .
[0022] [0022] According to the above aspect, the spacer is supported from the rear of the vehicle by the projection portion provided to the coupler member when the coupler member undergoes deformation or displacement and pushes the front side member through the spacer. Namely, (a portion which moves integrally together) the coupler member pushes the front side member through the spacer while supporting the vehicle rear spacer. The spacer can therefore be sustained while eliminating, or suppressing to a small degree, any detriment to collision performance in a small overlap collision.
[0023] [0023] The vehicle body front section structure of a ter-
[0024] [0024] According to the above aspect, the collision load is inserted into the coupler member, for example, in a frontal collision mode in which the load is inserted in the vehicle width direction outside the frontal side limb (referred to later as "small overlapping collision"). When the coupler member undergoes deformation or displacement under this load, a front end portion of the front side member is pushed towards the vehicle width direction outside since a front end side of the coupler member is interposed between the collision box and the front side member, and next to them. Furthermore, the front side member is pushed towards the vehicle width direction in the interior by the spacer positioned between the coupler member and the front side member which accompanies the deformation or displacement of the coupler member described above. The front side member bends accordingly, and the vehicle and the collision duplicate thereof are shifted in the vehicle width direction, thereby suppressing the collision duplicate from penetrating the vehicle body of the vehicle.
[0025] [0025] The vehicle body front section structure of the above aspect can consequently suppress vehicle body deformation in a small overlap collision. Furthermore, in a small overlap collision, the angled portion of the coupling member undergoes deformation or displacement so that it rotates about a portion attached to the front end of the front side member in the plan view. In accompaniment of this action, the projection portion that projects outward from the angled portion moves (oscillates around) to the vehicle rear of the spacer. The projection portion supports the spacer from the rear of the vehicle.
[0026] [0026] In the above aspect, a configuration can be elaborated in which in the coupler member, a front side in the vehicle longitudinal direction of a portion positioned in the vehicle width direction on the outside of the front side member configures an angled portion that is angled so that a rear side of the angled portion is spaced more in the vehicle width direction outside the front side member than a front side in the vehicle longitudinal direction of the angled portion in the plan view, and which additionally includes. a projection portion that projects outwardly from the angled portion of the coupler member towards a rearward in the direction.
[0027] [0027] According to the above aspect, in a small overlap collision, the angled portion of the coupler member undergoes deformation or displacement so that it rotates around a portion near the front end of the side member Front in flat view. In accompaniment of this action, the projection portion that projects outward from the angled portion moves (oscillates around) to the vehicle rear of the spacer. The projection portion supports the vehicle rear spacer.
[0028] [0028] In the above aspect, a configuration can be elaborated in which the projection portion and the coupling member are disposed in a separation for the spacer.
[0029] [0029] According to the above aspect, the projection portion and the coupling member are separated from the spacer. Consequently, in a collision mode other than a small overlap collision, such as a full overlap frontal collision, restricting or obstructing the behavior of the spacer, namely, of the front side member, by the support member and by the member coupler is effectively prevented or suppressed.
[0030] [0030] In the above aspect, a configuration can be elaborated in which the projection portion is formed integrally with the coupler member by flexing a portion of the coupler member.
[0031] [0031] According to the above aspect, the projection portion is formed by flexing the coupler member thereby enabling the projection portion (support member) to be provided without implying an increase in the number of components. ADVANTAGEOUS EFFECTS OF THE INVENTION

As illustrated in Figure 2, a vehicle body B of car A includes a pair of left and right front side members 12. The front side members 12 are respectively arranged with the length direction of the same in the longitudinal direction and are arranged side by side in the vehicle width direction. Each of the front side members 12 is joined through a collision box 14 to the bumper reinforcement 16 which is configured with the length direction of the same in the vehicle width direction. Namely, the bumper reinforcement 16 extends between the front ends of the left and right collision boxes 14.
[0062] [0062] The bumper reinforcement 16 of the present exemplary embodiment has a B-shaped cross-sectional profile as obtained orthogonally to the length direction thereof. Specifically, the bumper gusset 16 is configured with a B-shaped cross-section profile by joining a front panel 16F to the respective flanges of a rear panel 16R which is configured by a pair of upper and lower recessed portions that are open towards the front, the recessed portions being formed between three flanges, viz. an upper flange, an intermediate flange and a lower flange, so as to configure two portions in closed cross section in a row above and below each one. Note that a recessed portion that opens towards the rear is configured between the upper and lower closed cross-sectional portions. Although not illustrated in the drawings, microspheres that protrude outwards towards the rear (towards the interior of the closed cross-sections) to open towards the front may be formed along the vehicle width direction of the 16F front panel in the portions that configure front walls of the upper and lower closed cross-sections. The bumper reinforcement 16 is configured with high rigidity and resistance in relation to bending due to the employment of a structure, as in this example.
[0063] [0063] A radiator bracket 18 is fixed between the front portions of the left and right front side members 12. In the radiator bracket 18, both vehicle width steering ends of an upper member 18U and a lower member 18L that face each other both above and below are joined together by a pair of left and right side members 18S, so that the radiator bracket 18 is configured to include a portion formed with a frame shape. rectangular, as seen from the front. In the present exemplary embodiment, a central member 18C is provided to couple together the central portions in the direction.
[0064] [0064] An instrument panel 20 dividing an engine compartment E from cabin C is attached to a rear end side each of the front side members 12. More specifically, the rear portions of the front side members 12 are each configured with a 12K kick portion slanted so that a rear side is positioned lower than a front side thereof. Each 12K kick portion is joined to a front face side of the instrument panel 20. A lower rear end of each 12K kick portion is connected to an under-floor gusset that is adjacent to the underside of a floor panel. , not illustrated in the drawings. A vehicle-width steering center portion of the instrument panel 20 is formed with a tunnel section 20T that is connected to a T-floor tunnel.
[0065] [0065] A fender skirt 22 is provided in the vehicle width direction on the outside of each of the front side members 12. In the present exemplary embodiment, each fender skirt 22 forms a housing of wheel H which accommodates a front wheel, not illustrated in the drawings, so as to allow the front wheel to be driven, and is also formed with a 22S suspension tower. Each suspension tower 22S is configured to support an upper end portion of a suspension, not shown in the drawings, that supports the front wheels accommodated in the wheel housing H. In addition, a suspension member 24 supports the suspension is attached to each front side member 12. In the present exemplary embodiment, the suspension member 24 is an I-shaped suspension member with the length in the vehicle width direction and both ends of the suspension member 24 in the direction. of vehicle width support a lower arm, not illustrated in the drawings, which configures the suspension so that the lower arm is rotatable about a continuous geometric axis along the longitudinal vehicle direction.
[0066] [0066] The suspension member 24 is attached to the front side members 12 at several locations separate from each other for the forward and for the rear. Specifically, the front portions of both vehicle width direction outer ends of the suspension member 24 are joined via the arm members 24A to the longitudinal direction intermediate portions of the front side members 12 from below. Although not illustrated in the drawings, the aft portions of both outer vehicle width steering ends of the suspension member 24 are joined, both directly and indirectly, to the rear lower end portions of the 12K kick portions of the members. front sides 12.
[0067] [0067] A portion at a vehicle width inner steering end and a vertical steering lower end of each fender skirt 22 is joined to the corresponding front side member 12. A portion at an outer steering end end of vehicle width and at a vertical direction upper end of each fender skirt 22 is joined to an upper skirt member 26, this being a mounting member with the length direction in the longitudinal direction. Each upper skirt member 26 is disposed next to an outer vehicle-width steering outer end of a front upper section of vehicle body B, and a rear end portion of each upper skirt member 26 is joined to a canopy portion, not shown in the drawings. In other words, a rear end of the upper skirt member 26 is supported by the instrument panel 20 through the canopy portion. A front end side of each skirt upper member 26 is coupled through an extension 28 to an upper end of the side member 18S (a vehicle width steering outer end portion of the upper member 18U) which configures the radiator support 18 .
[0068] [0068] Although described in more detail later, the front flange 30 for joining to the crash box 14 is provided at a front end of each front side member 12. The front flange 30 is a member formed substantially in a hat shape. which opens towards the rear in the plan view and with the length of it continuous in the vertical direction. Front flange 30 protrudes outward and downward relative to front side member 12. A lower member 32, this being a member of continuous length from front to rear, engages between a lower portion of each front flange 30 and a vehicle-width steering end portion on the outside of a front portion of the suspension member
[0069] [0069] A flange 34F provided to a rear end of a barrel member 34 with length in the longitudinal direction is joined by gripping in the longitudinal direction to a forwardly facing face of the lower portion of each front flange 30. Each barrel member 34 is clamped together with fasteners 39, such as nuts and bolts, as illustrated in Figure 1, in a state in which the flange 34F formed at the rear end of the pipe member 34 is in face-to-face contact with a lower portion. of a 30F flange body. The underside bumper reinforcement 36 spans between the front ends of the left and right barrel members 34.
[0070] [0070] In the configuration described above, a power unit P (see Figure 3), this being a drive source for car A, is installed inside the engine compartment E. The power unit P is sustained forward or indirectly by locations that configure the vehicle body B, such as the left and right front side members 12 and the suspension member 24. The power unit P is disposed between the left and right front side members. CONFIGURATION OF RELEVANT PORTIONS FLANGE HOLDING STRUCTURE
[0071] [0071] The relevant portions of the vehicle body front section frame 10 are basically configured with lateral symmetry, so the following explanation mainly focuses on the frame on the left side. As illustrated in Figure 1, the front flange 30 described above is close to the front end of the front side member
[0072] [0072] As illustrated in Figure 3, Figure 6, and so on, several solder nuts 38 (four in this exemplary modality, which form a rectangular shape with the same length as continuous from top to bottom, as per viewed from the front) are provided on a rear face of the 30F flange body. As illustrated in Figure 3 and Figure 5, the sidewall 30S in the vehicle width direction inside the front flange 30 is disposed.
[0073] [0073] As illustrated in Figure 1, the rear flange 40 is provided to a rear end of the crash box 14. The rear flange 40 is configured with peripheral walls 40S that protrude outward a short distance towards the front from of peripheral edges of a 40F flange body. Although not shown in the drawings, bolt insertion holes are formed in the 40F flange body at positions corresponding to the weld nuts 38 of the 30F flange body.
[0074] [0074] The collision box 14 is joined to the front end of the front side member 12 by securing the rear flange 40 to the front flange 30 by screwing the screws 42 together with the weld nuts
[0075] [0075] The four gripping positions in which the solder nuts 38 and screws 42 are screwed together are respectively arranged so as to be both on the upper side and on the inner side of a centerline dividing an orthogonal cross-section for the length direction of the front side member 12 at top and bottom, and on both the left and right sides of a centerline that divides the cross-section into left and right. TOP SKIRT MEMBER
[0076] [0076] A forward-facing plate-shaped end plate 44 is joined to a front end of the upper skirt member
[0077] [0077] In the present exemplary embodiment, a structural body configured by joining the fender skirt 22, the upper skirt member 26 and the end plate 44, or any one of these two members in isolation, corresponds to a fender skirt of the present invention. COUPLING MEMBER
[0078] [0078] The vehicle body front section structure 10 includes the coupler member 46 which couples the front end of the upper skirt member 26 to the front end of the front side member 12. The coupler member 46 is configured with main portions of a barrel. 48, which serves as a main body having a closed cross-sectional frame, a rear flange 50 provided at a rear end of barrel 48, and a front side joint portion 52 provided at a front end of barrel 48.
[0079] [0079] As shown in Figure 3 and Figure 4, the rear flange 50 is close to the front end of the upper skirt member 26 by joining it, by pressure, to the rectangular plate portion 44A of the end plate 44 by screwing together the bolts 58 and the weld nuts 59. Namely, the coupler member 46 is joined to the upper skirt member 26 through the end plate 44. Consequently, the gripping direction of the coupler member 46 to the upper skirt member 26, namely to the end plate 44, is substantially aligned in the longitudinal direction.
[0080] [0080] As illustrated in Figure 1, the barrel 48 is, for example, formed by flexing a barrel member and is bent in the manner described below so as to engage between the front end of the upper skirt member 26 and the end. front side member 12, which are in different positions in relation to each other, in the longitudinal direction, in the vertical direction and in the vehicle width direction. In the present exemplary embodiment, the barrel 48 is formed such that a rear portion 48R, an intermediate portion 48C and a front portion 48F are connected together in that sequence from the rear.
[0081] [0081] The rear portion 48R is formed in a circular arc shape, as seen from the side, is arranged so that an upper rear end thereof is in a direction tangential to the longitudinal direction and is joined to the rear flange 50. The portion The front side 48F is formed in an angled straight line format so that a rear side of the front portion 48F is separated more towards the vehicle width direction on the outside of the front side member 12 than a front side of the front portion 48F in the plan view . A front end 48FF of the front portion 48F configures an open end that opens towards the front and the vehicle width direction on the inside to the vehicle width direction on the outside of the crash box 14. The intermediate portion 48C is formed of so as to connect the rear portion 48R and the front portion 48F to each other. Specify
[0082] [0082] As illustrated in Figure 3, in the plan view of the barrel 48, the rear portion 48R has mainly a straight-line shape that continues along the longitudinal direction, and the intermediate portion 48C and the front portion 48F are formed into a shape straight angled so that the rear side is separated more to the vehicle width direction on the outside of the front side member 12 than the front side. In plan view, a vehicle width direction inner end portion of the front end 48FF of the front portion 48F (omitted by flange 52F, described later in Figure 1) is positioned (in the vicinity of) in the width direction of vehicle outside the junction portion between the front side member 12 and the crash box 14.
[0083] [0083] As illustrated in Figure 4, in the side view of the barrel 48, the front portion 48F (a portion mainly omitted by the flange 52F, described later in Figure 4) configures a continuous horizontal portion in a substantially horizontal plane (to the along the length direction of the front side member 12). The front side joint portion 52 is joined to the substantially horizontal front portion 48F. In other words, as seen from the side, a portion of the main body that extends rearwardly from the front side joint portion 52 along the length direction of the front side member 12 (the horizontal direction) configures the front portion 48F, and the front portion 48F corresponds to a horizontal portion.
[0084] [0084] The front side joint portion 52 is configured to include the flange 52F which is secured to the rear flange 40 of the crash box 14 and the front flange 30 of the front side member 12 and a portion joined to a pipe 52C which is joined to the 48F front portion of the barrel
[0085] [0085] A portion of the main panel 54 in the vehicle width direction outside the flange configuring portion 52F is angled to follow the length direction of the front portion 48F of the barrel 48 and is formed with a recess 54N having in a semicircular shape so as to cover the rear of the front portion. As illustrated in Figure 7, gusset panel 55 is formed with a hat-shaped cross-section enclosing barrel 48 which fits into recess 54N. Consequently, at the portion joined to a pipe 52C, both the main panel 54 and the gusset panel 55 form a shoulder along the vertical direction on both sides of the pipe 48.
[0086] [0086] In the portion joined to a pipe 52C, the pipe 48 and the front side joint portion 52 are joined together by welding at the respective portions in a state in which the front portion 48F is fitted into the recess 54N, and the pipe 48 is covered by a gusset panel 55. More specifically, the gusset panel 55 and the main panel 54 are joined together by performing a long weld (either continuously or intermittently; the same applies below) along the length direction of the front portion 48F (a direction orthogonal to the cross section shown in Figure 7) in the arc welding portions AW1 shown in Figure 7. Main panel 54 and front portion 48F of pipe 48 are joined together a long weld along the length direction of the 48F front portion in AW2 arc weld portions. Reinforcement panel 55 and front portion 48F of barrel 48 are also joined together by making a long weld along the length direction of front portion 48F into an arc welding portion AW3.
[0087] [0087] The reinforcement panel 55 is superimposed with the main panel 54 at two locations framing the recess 54N in the vertical direction, and the arc welding portions AW1 with configured by fillet welds (overlapping joints) along the upper and lower edge portions of gusset panel 55. An elongated hole 55H, with the length thereof along the length direction of front portion 48F, is formed in a direction towards the intermediate vertical portion of gusset panel 55, and the arc welding portion AW3 is configured by a fillet weld (an lap joint) along a lower edge of the elongated hole 55H. The arc welding portions AW2 are formed by the open end arc welding of recess 54N and a peripheral face (the front portion 48F) of the pipe 48 along the length direction of the front portion 48F.
[0088] [0088] The front side joining portion 52 can be understood as a configuration in which the flange 52F is a single member configuration of the main panel 54, and the pipe joint portion 52C is a two member configuration of the main panel 54 and the father-
[0089] [0089] In the coupler member 46 described above, the rear flange 50 is close to the end plate 44 securing from the front, and the flange 52F of the front side joint portion 52 is secured together with the rear flange 40 and the front flange 30 in a state interposed between them. The coupler member 46 is thereby configured to couple the front end of the upper skirt member 26 and the front end of the front side member 12 together.
[0090] [0090] In other words, the coupler member 46 of the present exemplary embodiment can be understood as a mounting member supported by the front side member 12 and the upper skirt member 26 in a state in which the coupler member 46 forms a shoulder towards the vehicle width direction outdoors relative to front side member 12. As illustrated in Figure 3, coupler member 46 is also configured to form a large shoulder for vehicle width direction outdoors relative to the bumper reinforcement. 16. The coupler member 46 can therefore be understood to be effectively a collision load input location in a collision mode in the vehicle width direction outside the front side member 12.
[0091] [0091] In the present exemplary embodiment, as described above, a portion on the front end side of the coupler member 46, namely, the front portion 48F and the intermediate portion 48C of the barrel 48 and the portion joined to a barrel 52C of the front side joint portion 52, are angled so that the back side is farther away from the front side member 12 than the front side in plan view. As illustrated in Figure 3, the front end 48FF of the barrel 48 that configures the coupler member 46 protrudes outward further than the front end of the front side member 12. SPACER
[0092] [0092] As illustrated in Figure 1 and Figure 3, a spacer 56 is provided to a portion of a side face facing away from vehicle width direction 12S2 of front side member 12 which is in vehicle width direction inside the coupler member 46. In other words, the spacer 56 is disposed in a portion positioned between the front side member 12 and the coupler member 46 in plan view. Furthermore, as illustrated in Figure 4, viewed from the side, spacer 56 is disposed in vertical direction overlap with front side member 12 and a portion on the front end side of coupler member 46.
[0093] [0093] More specifically, the spacer 56 overlaps the front portion 48F of the barrel 48 which configures the coupler member 46 in the vehicle width direction and in the vertical direction, as viewed from the front (as viewed along the arrow X in Figure 3), and overlaps the front portion 48F of the barrel 48 that configures the coupler member 46 in the longitudinal direction and in the vertical direction, as seen from the side (as seen along arrow Y in Figure 3, see also Figure 4). Namely, the spacer 56 is disposed facing the front portion 48F of the coupler member 46. The spacer 56 may also be understood to be disposed facing the portion joined to a pipe 52C that serves as an opposing face portion. of the front lateral junction portion 52 of the coupling member 46.
[0094] [0094] When the coupler member 46 receives a load towards the rear and deforms, (a portion of the front side joint portion 52 that fits together with) the front portion 48F of the barrel 48 that configures the coupler member 46 is configured to be impinged on the spacer 56. A portion of the spacer 56 on which the then deformed coupling member 46 is impinged forms an angled face.
[0095] [0095] The spacer 56 is joined to a portion of the front side member 12 positioned slightly in front of the power unit P and protrudes outward from the side face 12S2 of the front side member 12 towards the outside vehicle width direction in that portion. In the present exemplary embodiment, as illustrated in Figure 3 and Figure 4, the joining structure of the spacer 56 to the front side member 12 employs a fastener with fasteners that include screws 60 in flanges 56F that form a shoulder fore and aft of the spacer 56.
[0096] [0096] The spacer 56 is configured to function as a load transmitting member which transmits load from the coupler member 46 to the front side member 12 when the coupler member 46 is impinged on the spacer 56 as described above. This load transmission promotes the bending of the front side member 12 in the vicinity of the power unit P, as will be explained later under Operation of the present exemplary mode.
[0097] [0097] The spacer 56 can be configured to employ a lightweight (low density) material such as aluminum (or an alloy thereof) or resin, as long as it functions as a load transmitting member as described above. OPERATION
[0098] [0098] The explanation follows in relation to the operation of this exemplary modality. OPERATING IN A SMALL OVERLAY COLLISION
[0099] [0099] The following explanation refers to Figure 8, in relation to the operation of car A applied with the vehicle body front section structure 10 configured, as described above in the case of a small overlap collision, this being a collision mode in which a collision body (barrier Br) collides in the vehicle width direction on the outside of the front side member 12. The illustrated example shows a case in which the barrier Br collided in the width direction of vehicle outside the front side member 12 on the left side. Note that bumper reinforcement and the like are not illustrated in Figure 8B to Figure 8E after the collision.
[00100] [00100] In an early stage of the small overlap collision described above, as illustrated in Figure 8A, a rear load is inserted from barrier Br to a portion of the bumper reinforcement 16 in the width direction of vehicle on the outside of the front side member 12. When the high strength bumper reinforcement 16 with a B-shaped cross section transmits a collision load to the collision box 14, the collision box 14 is compressed in the longitudinal direction, as illustrated in Figure 8B. Energy is consequently absorbed in the early stage of the collision.
[00101] [00101] Then, when the barrier Br reaches a location that is impinged on the coupler member 46, as illustrated in Figure 8C, a load Fy towards the interior vehicle width direction is generated on the front portion 48F, where barrel 48 of coupler member 46 is angled in plan view. Load Fy acts as a force in one direction to move carriage A and barrier Br separately in the vehicle width direction. Namely, the carriage A and the barrier Br are displaced in the vehicle width direction due to the barrier Br which is impinged on the coupler member 46, promoting the sliding of the carriage A and the barrier Br against each other. Barrier Br is thus suppressed from penetrating carriage A.
[00102] [00102] When the barrier Br pushes the coupler member 46 towards the rear, the front end of the front side member 12 is pu-
[00103] [00103] The front side member 12 pushes the power unit P towards the interior vehicle width direction due to this bending. A lateral force (force due to inertia) inserted in the power unit P, being this (a) section in which the mass is concentrated in car A, moves car A itself towards an opposite side to the collision (away from the barrier Br in the vehicle width direction). Car A and barrier Br are then further induced to slide with each other, and localized deformation of a collision side end section of vehicle body B is effectively prevented or suppressed. COUPLING MEMBER OPERATION
[00104] [00104] A portion on the front end side of the coupler member 46, namely, the front portion 48F and the intermediate portion 48C of the barrel 48, and the pipe adjoining portion 52C of the front side junction portion 52, is angled from so that a rear side is more distantly separated from the front side member 12 than a front side in plan view. When the barrier Br (another car or the like) collides with this angled portion, the angled portion converts a portion of the collision charge into the charge Fy towards the opposite side of the collision. The coupler member 46 consequently promotes displacement in the vehicle width direction relative to the barrier Br, namely, it promotes sliding beyond the barrier Br described above.
[00105] [00105] The portion on the front end side of the coupling member 46 is angled as described above so that the coupling route between the front side member 12 and the end plate 44 is shorter than in a L-shaped coupler member with a portion that forms a shoulder along the vehicle width direction and an extension portion that extends from the shoulder-forming portion towards the rear in the plan view. Under deformation or rear displacement that accompanies the small overlap collision, the coupler member 46 consequently acts to pull the front end of the front side member 12 towards the outer vehicle width direction with less freedom of action (free movement distance) than the coupling member in the comparative example above. The coupler member 46 consequently works with the spacer 56 to significantly promote the bending of the front side member 12.
[00106] [00106] The front flange 30 that is joined to the front side joint portion 52 of the coupler member 46 includes the side walls 30S. The side walls 30S function to push the front end of the front side member 12 in the vehicle width direction when the front end of the front side member 12 is pulled towards the vehicle width direction outside due to the barrier Br pushing the coupler member 46 towards the rear. Consequently, when the front end of the front side member 12 is being pulled towards the outer vehicle width direction, it cannot rely solely on the shear of the screws 42, since in a comparative example the side walls 30S are not included. Consequently, in the vehicle body front section structure 10, the force to pull the front end of the front side member 12 towards the vehicle width direction abroad can be made to act efficiently in a collision of small overlap.
[00107] [00107] In addition, the weld nuts 38 and bolts 42 that secure the coupling member flange 52F to the front flange 30 of the front side member 12, and the like, include those positioned further to one direction of vehicle width in the interior than a centerline that divides the front side member 12 into left and right. Consequently, in a small overlap collision, the entire front end (the entire cross-section) of the front side member 12 is pulled towards the outer vehicle width direction, as opposed to a configuration in which the flange 52F it is only attached to the front flange 30 in the vehicle width direction outside the centerline. Furthermore, in the coupler member 46 described above, the flange 52F is secured together with the front flange 30 on both sides of the vehicle's width direction. A concentration of load (stress) at a specific joint location outside of several joint portions that are secured together may therefore be better suppressed than in a configuration in which the 52F flange is fastened only together with the front flange 30 on one side of the centerline.
[00108] [00108] In the vehicle body front section structure 10, the front end of the front side member 12 is efficiently pulled towards the outer vehicle width direction in a small overlap collision, which contributes for folding the front side member 12 into an appropriate location and at an appropriate time. Furthermore, a front end 48FF of the barrel 48 which configures the coupler member 46 protrudes outward further than the front end of the front side member 12. Consequently, the coupler member 46 may begin to pull the front end of the side member. front 12 towards the vehicle width direction outside after the collision box 14 has been compressed and before the front side member 12 is compressed by the collision load. The front side member 12 can be made to consequently stably bend towards the vehicle width direction inside (the bending direction of the front side member 12 is stabilized).
[00109] [00109] In the coupler member 46 that configures the vehicle body front section structure 10, the front side joint portion 52 that is joined to the barrel 48 has the configuration of two members of the main panel 54 and the reinforcement panel 55. This allows for more portions of arc welding with the 48 barrel than a comparative example employing a front flange configured by a single member. This thus enables the weld between the barrel 48 and the front side joint portion 52 to be prevented or completely suppressed from disintegrating in a small overlap collision, and enables the coupler member 46 to effectively pull the front end of the front side member 12 towards the vehicle width direction outside.
[00110] [00110] Furthermore, with the coupler member 46 in a comparative example with through holes to join the coupler member formed in the front side member, if the collision design is carried out for a fixed coupler member state, there may be a concern that through holes would be detrimental to collision performance in configurations where a coupler member is not actually provided. Namely, there is concern about variation in head-on collision performance between enclosures in which a coupling member is adjacent to the through holes, and between enclosures in which a coupling member is not adjacent to the through holes. In the comparative example, in which the front side member is formed with through holes for the above purpose, it is therefore difficult to develop common structures for vehicles not provided with a coupling member.
[00111] [00111] However, in the coupler member 46, a flange 52F of the front side joint portion 52 is joined to the front end of the front side member 12 in a state interposed between the front flange 30 of the front side member 12 and the flange rear 40 of the crash box 14. In this way, this enables the coupler member 46 to be provided to react to small overlapping collisions, while preventing or suppressing any detriment to energy absorbing characteristics during a collision ( collision performance in head-on collisions) due to the similar front side member 12 in the vehicle body front section structure 10.
[00112] [00112] Consequently, the vehicle body front section structure 10 enables the deformation of the vehicle body in a small overlap collision to be suppressed with the use of the coupler member 46 that couples the front side member 12 and the end plate 44 to each other, while preventing or suppressing any detriment to collision performance due to the front side member 12.
[00113] [00113] The vehicle body front section structure 10 enables the front side member 12 and the crash box 14 to be made common to vehicles in which the coupler member 46 is not provided (such as, vehicles that have a different structure to react to small overlap collision), while suppressing any detriment to collision performance in head-on collisions. Namely, a configuration in which the coupler member 46 is provided to suppress deformation of the vehicle body in a small overlap collision can be made common for a vehicle body structure of a vehicle not provided with the coupler member 46.
[00114] [00114] In particular, the rear flange 50 on the rear end side of the coupler member 46 is secured to the upper skirt member 26 with the use of screws 58 and weld nuts 59, and the front side joint portion 52 on the side The front end is fastened together to the front flanges 30, 40 using screws 42 and weld nuts 38. different structures of the coupler member 46, compared to a comparative example in which, for example, both the front and rear ends, or one of them, of a coupler member are joined to the vehicle body B by welding or similar.
[00115] [00115] The coupler member 46 is joined to the end plate 44 by gripping along the longitudinal direction using screws 58 and weld nuts 59. In a comparative example in which, for example, a coupler member is attached with the use of bolts, or the like, which penetrate in the vehicle width direction through a wall portion of the upper skirt member 26 with the length thereof in the longitudinal direction, the collision load is generated by the shearing of the bolts. In contrast, since the gripping direction for the end plate 44 is the longitudinal direction, the collision can load is borne as an axial force by the coupler member 46 (the rear portion 48R of the barrel 48). The coupler member 46 can therefore effectively receive the load of the BUMPER STRENGTH barrier, without relying on the shear impact strength of the bolts 58. SPACER OPERATION
[00116] [00116] Furthermore, the spacer 56 is provided between the front side member 12 and the coupler member 46 and overlaps the front side member 12 and the coupler member 46 in the vertical direction. Consequently, when the coupler member 46 that has been deformed or displaced towards the rear due to the collision load in a small overlap collision that is foisted on the spacer 56, the spacer 56 pushes the front side member 12 towards the direction of vehicle width inside as described above. This operation, together with the operation of the coupler member 46 to pull the front end of the front side member 12 towards the vehicle width direction outside, promotes the bending of the front side member 12 on the side of the power unit and promotes the vehicle width direction shift between car A and barrier Br.
[00117] [00117] In particular, the spacer 56 is provided in the vehicle width direction outside facing the side face 12S2 of the front side member 12. Consequently, a specific location of the front side member 12 (the location where the spacer 56 is installed) is pushed towards the interior vehicle width direction by spacer 56 in a small overlap collision. Thus, this enables the front side member 12 to be bent into an appropriate location in a minor overlap collision.
[00118] [00118] The front portion 48F of the barrel 48 of the coupler member 46 extends substantially horizontally from the front side joint portion 52 towards the rear, as viewed from the side. The front portion 48H is consequently suppressed from being displaced or deformed in the vertical direction by the rear load from the barrier Br and is displaced or deformed along a substantially horizontal plane. The load of the front portion 48H is transmitted by the spacer 56 as a force to push the front side member 12 towards the vehicle interior width direction. The component force in the vertical direction can be consequently suppressed during the transmission of this load, thereby improving the efficiency of load transmission from the coupler member 46,
[00119] [00119] The pipe joint portion 52C of the front side joint portion 52 of the coupler member 46 forms a shoulder in the vertical direction relative to the front portion 48F and faces the spacer.
[00120] [00120] The explanation follows in relation to a vehicle body front section structure 65 according to a second exemplary embodiment of the present invention, with reference to Figure 9 to Figure 12. Note that the components and the portions that are basically the same as those in the first exemplary modality are assigned the same reference numerals as in the first exemplary modality, and the explanation and illustration of the mesos are omitted as appropriate.
[00121] [00121] Figure 9 is a perspective view of the vehicle body front section structure 65, corresponding to Figure 2.
[00122] [00122] Note that, as illustrated in Figure 3, in the present exemplary embodiment, an apex portion 56T in which the spacer 56 forms a shoulder more towards the vehicle width direction is positioned substantially at the center of the spacer's longitudinal direction. 56. Spacer 56 is formed with a supported face 56S, that face being angled so as to face toward the vehicle width direction on the outside and to the rear in the plan view at the rear of the apex portion 56T. SUPPORT MEMBER
[00123] [00123] As illustrated in Figure 10, support member 62 is provided to protrude outward towards the side of spacer 56 on front portion 48F (which may encompass a portion of intermediate portion 48C positioned adjacent an enclosure with the same), this being the angled portion of the barrel 48 that configures the coupler member 46. The support member 62 has a narrow width on a front end side 62P positioned more to the spacer side 56 than a front end. base 62B on the side adjacent to barrel 48. Support member 62 has a wedge-shaped outer profile in plan view. A structure for attaching support member 62 to barrel 48 employs gripping with the use of fasteners including screws 64.
[00124] [00124] Support member 62 protrudes outward from barrel 48 to the side of spacer 56 so that the an-
[00125] [00125] When the barrel 48 of coupler member 46 rotates (is deformed or displaced) around the front end thereof (a vehicle width direction outer end of flange 52F) in the direction of arrow R in Figure 10 in In plan view, the support member 62 described above oscillates around towards the rear of the support member 56S of the spacer 56. The support member 62 comes into contact with or comes extremely close to the support member 56S in this state of oscillation around. OPERATION
[00126] [00126] The explanation follows in relation to the operation of the second exemplary mode.
[00127] [00127] Note that coupling member operation and spacer operation in a small overlap collision are similar to coupler member operation and spacer operation in a small overlap collision in the front section structure of vehicle body of the first exemplary modality, then their explanation is omitted. SUPPORT MEMBER OPERATION
[00128] [00128] As illustrated in Figure 12A to Figure 12C, when the coupler member 46 deforms until it is impinged on the spacer 56, the support member 62 provided to the coupler member 46 swings around to the rear of the sustained face 56S of the spacer 56 while undergoing rearward displacement with coupler member 46. Namely, support member 62 oscillates adjacent to the vicinity of the rear side of spacer 56 which accompanies rotation around. from the front end side of the coupler member 46. Accordingly, as shown in Figure 12D, the spacer 56 transmits load from the coupler member 46 to the front side member 12 while the bearing face 56S is rearwardly supported by the member. of support 62.
[00129] [00129] Note that the spacer 56 is subject to a shear load between the spacer 56 and the front side member 12 (the side face 12S2) due to the load of the coupler member 46. In the vehicle body front section structure 65, this shear load is supported by the support member 62 so that the positional displacement of the spacer 56 relative to the front side member 12 in the longitudinal direction and the decoupling of the spacer 56 from the front side member 12 effectively prevented or suppressed. Support member 62 provided to coupler member 46 is moved towards the rear near coupler member 46 (spacer 56). Consequently, displacement and positional decoupling of the spacer 56 relative to the front side member 12 is effectively prevented or suppressed due to the obstructing movement of the spacer 56 towards the rear.
[00130] [00130] In a small overlap collision, load transmission to the front side member 12 is consequently promoted compared to a comparative example in which support member 62 is not provided. Namely, the operation of the supporting member
[00131] [00131] In the vehicle body front section structure 65, the support member 62 and the coupler member 46 are arranged in a separation from the spacer 56. Consequently, the movement of the spacer 56 is effectively suppressed or prevented from being restricted. - to or avoided by the support member 62 and the coupler member 46 in collision modes other than a minor overlap collision, such as a full overlap frontal collision. Namely, in a collision mode other than a small overlap collision, the restriction of the front side member 12 by the support member 62, or interference thereto, and by the coupler member 46 is prevented or suppressed from effective way due to the spacer
[00132] [00132] Support member 62 is accordingly provided so that collision modes other than a small overlap collision are not detrimental to collision performance and also enables improved collision performance in a small overlap collision. In particular, the entire support member 62 is moved away in the vehicle width direction outwardly with respect to the spacer 56. The support member 62 is therefore not impinged during a simple backward movement of the spacer 56, enabling that any detriment to collision performance is kept small in collision modes other than a small overlap collision. THIRD EXEMPLARY MODALITY
[00133] [00133] The explanation follows in relation to a vehicle body front section structure 70 of a third exemplary Modality of the present invention, with reference to Figure 13 and Figure 14. Note that the components and the portions that are basically the same as those of the first or second exemplary embodiment are assigned the same reference numerals as in the first or second exemplary embodiment, and the explanation and illustration thereof are omitted as appropriate.
[00134] [00134] Figure 13 is a plan view corresponding to Figure 10 and illustrates the relevant portions of the vehicle body front section structure 70. As illustrated in Figure 13, a coupler member 72 that configures the section structure Vehicle body front 70 is configured with main portions of a barrel 74 which serves as a main body, with the front side joint portion 52 and with the rear flange 50. The barrel 74 differs from the barrel 48 in point wherein it is formed with a projection portion 74P, which serves as a support member, the barrel member of which it is made flexing. Below is the explanation of the same.
[00135] [00135] Pipe 74 includes a rear portion 74R formed similarly to rear portion 48R and a front portion 74F that is configured similarly to front portion 48F at least in one location adjacent to a pipe adjoining portion 52C of the side joint portion front 52. The barrel 74 additionally includes an intermediate portion 74C that connects between the rear portion 74R and the front portion 74F. The projection portion 74P is formed for a portion that includes part of the intermediate portion 74C on the front portion side 74F or that includes a rear end side of the front portion 74F and part of the intermediate portion 74C on the front portion side 74F.
[00136] [00136] In plan view, the projection portion 74P protrudes outward to the spacer side 56 of a hypothetical line IL that connects between a boundary of the intermediate portion 74C with the rear portion 74R and the front portion 74F , in flat view. Namely, in the present exemplary embodiment, the projection portion 74P is configured to project outwardly to the spacer side 56 of an angled portion formed by the front portion 74F and the intermediate portion 74C. More specifically, the projection portion 74P is an inflected portion (inflected portion) formed in a substantially V-shape that opens forward and towards the vehicle width direction outside in the plan view by flexing at three flexion locations 74B1 , 74B2 and 74B3.
[00137] [00137] Although not illustrated in the drawings in the drawings, the projection portion 74P overlaps the spacer 56 in the vertical direction at least in a region from the boundary with the front portion 74F to an apex portion 74PP in the flexion of the V-shape. In the projection portion 74P, the position of the apex portion 74PP relative to the spacer 56 is similar to the position of the front end 62P of the support member 62. Along with the coupler member 72, the projection portion 74P is accordingly disposed at a separation from the spacer 56 and the entire projection portion 74P is disposed away from the vehicle width direction outside with respect to the spacer 56.
[00138] [00138] When the barrel 74 of coupler member 72 rotates (is deformed or displaced) around a front end (a vehicle width direction outer end of flange 52F) in the direction of arrow R in Figure 13 in plan view, the projection portion 74P configured as described above swings around to the rear of the support face 56S of spacer 56 (see Figure 14). The 74P projection portion contacts or approaches ex-
[00139] [00139] The explanation follows regarding the operation of the 74P projection portion of the third exemplary Modality. As illustrated in Figure 14, when the coupler member 72 deforms until it is impinged on the spacer 56, the projection portion 74P that is integrally formed with the coupler member 72 swings around to the rear of the sustained face 56S of the spacer 56 Namely, the projection portion 74P oscillates around to the adjacencies of the rear side of the spacer 56 which accompanies the rotation of the coupler member 72 about the front end side thereof. Spacer 56 consequently transmits the load from coupler member 72 to front side member 12 at the same time as supported face 56S is supported at the rear by projection portion 74P.
[00140] [00140] In a small overlap collision, the shear load on the spacer 56 caused by the load received from the coupler member 72 is consequently supported at the rear by the projection portion 74P. Consequently, the positional displacement of the spacer 56 in the longitudinal direction relative to the front side member 12 and the uncoupling of the spacer 56 from the front side member 12 are effectively prevented or suppressed.
[00141] [00141] The vehicle body front section structure 70 according to the third exemplary Embodiment thereby exhibits a similar operation to the vehicle body front section structure 10, according to the first exemplary embodiment, and can obtain hence an operation similar to the vehicle body front section structure 10 according to the first exemplary embodiment. The operation of the coupler member 46, and the operation and advantageous effects of the spacer 56 are also basically the same as those in the vehicle body front section structure 10, enabling a similar operation to the vehicle body front section structure. vehicle 10 is obtained.
[00142] [00142] In the vehicle body front section structure 70, the projection portion 74P is formed integrally by flexing the barrel 74 that configures the coupler member 72 thereby enabling that projection portion 74P, which serves as a supporting member, is provided without implying an increase in the number of components. FOURTH EXEMPLARY MODALITY
[00143] [00143] The explanation follows in relation to a vehicle body front section structure 80 according to the fourth Exemplary Modality of the present invention, with reference to Figure 15. Note that components and portions are basically the same that those of the first or second exemplary embodiment are assigned the same reference numerals of the first or second exemplary embodiment, and the explanation and illustration thereof are omitted as appropriate.
[00144] [00144] Figure 15 is a plan view corresponding to Figure 10, which illustrates relevant portions of the vehicle body front section structure 80. As shown in Figure 15, the vehicle body front section structure 80 differs from the first embodiment exemplary at the point where a support member 82 is provided in place of the support member 62. The following is the specific explanation thereof.
[00145] [00145] The support member 82 is formed as a substantially L-shaped member in the plan view. More specifically, support member 82 is configured as a support plate 82S that protrudes from an end portion of a base plate 82B. In the present exemplary embodiment, support member 82 is formed into an L-shape as described above by bending (pressing) a metal sheet such as steel sheet or aluminum sheet.
[00146] [00146] The base plate 82B is joined to the front portion 48F (which covers a portion in the vicinity of the boundary between the front portion 48F and the intermediate portion 48C) of the barrel 48, and the support plate 82S is superimposed on the support face 56S of spacer 56 and gasket to spacer 56. Joining structures employ gripping with the use of fasteners including screws 84.
[00147] [00147] The explanation follows regarding the operation of the support member 82 of the fourth Exemplary Modality. In vehicle body front section structure 80, support member 82 couples coupler member 46 and spacer 56 to each other. Spacer 56 consequently transmits the load from coupler member 46 to front side member 12 while bearing face 56S is rearwardly supported by support member 82.
[00148] [00148] The shear load on the spacer 56 due to the load received from the coupler member 46 in a small overlap collision is consequently supported at the rear by the support member 82. Consequently, the positional displacement of the spacer 56 in the longitudinal direction relative to to front side member 12 and decoupling of spacer 56 from front side member 12 are effectively prevented or suppressed.
[00149] [00149] The vehicle body front section structure 80, according to the fourth Exemplary Modality, consequently exhibits similar operation and advantageous effects to the vehicle body front section structure 10, according to the first mode. exemplary functionality, with the exception that the operation is due to the arrangement of the support member 62 in a separation from the spacer 56. Due to the sharing of a common operation with the vehicle body front section structure 10, the effects
[00150] [00150] In the first to fourth Exemplary Modalities described above, the explanation has been given in relation to the examples in which the barrel 48 configures the main body of the coupler member 46; however, the present invention is not limited thereto. For example, in place of the barrel portion 46, a coupler member with a main body configured with a closed cross-sectional structure joining several members, such as a coupler member 102, described later, or a coupler member with a body main configured by (bending of) an extrusion molded component can be employed.
[00151] [00151] In each of the exemplary embodiments described above, an explanation has been given in relation to the examples in which the rear end of the coupler member 46 is adjacent to the end plate 44; however, the present invention is not limited thereto. For example, as in coupler member 102, a coupler member may be employed with a rear end joined to the upper skirt member 26 or the fender skirt 22.
[00152] [00152] In each of the exemplary embodiments described above, an explanation has been given in relation to the examples in which the front side joining portion 52 includes the main panel 54 and the gusset panel 55; however, the present invention is not limited thereto. For example, a front side seam portion may be employed with a frame in which the barrel 48 (main body) is confined by flexing a single panel (a frame in which a single panel forms a pair of plate portions). Furthermore, for example, a front side joint portion which is joined only to the barrel 48 (main body) from one side may be employed. As another example, a front side joint portion configured from three or more panels can be employed. Namely, it suffices that the front side joint portion is joined to the barrel 48 (main body) with the required strength for the load received in a small overlap collision.
[00153] [00153] Furthermore, in each of the exemplary embodiments described above, an explanation has been given in relation to the examples in which the barrel 48 of the coupler member 46 includes the front portion 48F that serves as a horizontal portion; however, the present invention is not limited thereto. For example, the configuration can be made with a coupler member in which a front portion, viz. a portion that overlaps the spacer 56 in the vertical direction, includes a pipe that is angled or curved with respect to the length direction of the front side member 12 as seen from the side.
[00154] [00154] In each of the exemplary embodiments described above, an explanation has been given in relation to the examples in which the spacer 56 provided to the side face 12S2 of the front side member 12 is attached thereto; however, the present invention is not limited thereto. For example, spacer 56 can be joined to front side member 12 by joining structures with the use of soldering, brazing, bonding, or the like. The present invention, in which the spacer is supported at the rear by a support member (projection portion) in a small overlapping collision, makes it possible for the joint structure to be simplified. FIFTH EXEMPLIFICATION MODE
[00155] [00155] Figure 16 is a perspective view illustrating the confi-
[00156] [00156] As illustrated in Figure 16 to Figure 18, the vehicle body front section structure 100 includes a coupler member 102 with a closed rectangular cross-section in place of the coupler member 46 which includes the barrel 48 with a cross-section closed circular. The vehicle body front section structure 100 further includes a spacer (projection member) 104 adjacent to the coupler member 102 in place of the spacer 56 disposed at a separation from the coupler member 46. The following is an explanation of the same. COUPLING MEMBER
[00157] [00157] The coupler member 102 extends integrally outwardly from a front end portion of the upper skirt member 26, and a front end portion of the coupler member 102 is secured to a front end portion of the front side member 12 Specifically, the coupler member 102 is formed with a rear portion 102R, an intermediate portion 102M and a front portion 102F connected in sequence from the rear.
[00158] [00158] The rear portion 102R of the coupler member 102 extends downward and toward the front end portion of the upper skirt member 26. The rear portion 102R of the present exemplary embodiment is angled at a closer angle to vertical than to horizontal, as illustrated in Figure 18. Intermediate portion 102M extends down and forward from a front end portion of rear portion 102R. The middle portion 102M has a tilt angle closer to horizontal than the rear portion 102R, as viewed from the side, and is set at a tilt angle of approximately 45° in the present exemplary embodiment. As illustrated in Figure 17, the intermediate portion 102M is angled so that, in plan view, a front side is closer to the front side member 12 than a rear side in the vehicle width direction.
[00159] [00159] The front portion 102F of the coupler member 102 is disposed at the same height as the front side member 12 (overlapping in the vertical direction) and is positioned in the vehicle width direction on the outside of a front portion of the member front side 12. A front end side of the front portion 102F extends towards the vehicle interior width direction and reaches between the front side member 12 and the crash box 14. A width direction face. vehicle outside coupler member 102 (in particular front portion 102F and intermediate portion 102M) configures a curved face 102C that curves so that a rear side faces more to the vehicle width direction outside than one side. front.
[00160] [00160] A further explanation is given in relation to the general structure of the coupler member 102, before proceeding to an explanation in relation to a joint structure between the front portion 102F and the front side member 12 and the box. collision 14. In the coupler member 102, an outer panel 108 with a hat-shaped cross-section that opens towards the vehicle width direction in the interior and an inner panel 110 with a hat-shaped cross-section that opens towards the direction of vehicle width on the outside (see Figure 17) are joined at respective top and bottom flanges. The coupler member 102 is then formed with a cross-sectional structure closed with a rectangular cross-section, as described above. On the front portion 102F side of the coupler member 102, the outer panel 108 is configured with a hat-shaped cross-section that opens in a substantially rearward direction, and the inner panel 110 is plate-shaped. flat against the upper and lower flanges of the outer panel 108.
[00161] [00161] As illustrated in Figure 12, a flat plate-shaped flange 110F extends outward towards the vehicle width direction inside from a vehicle width direction interior end portion of the front portion 102F of the panel interior
[00162] [00162] The plate thickness direction of the 110F flange is continuous in the longitudinal direction, and an intermediate vertical portion direction of the 110F flange is cut away from the interior vehicle width direction. Flange 110F is interposed between the flange body 30F of the front flange 30 provided to the front side member 12 and the flange body 40F of the rear flange 40 provided to the collision box 14. Furthermore, the flange 110F is joined between the flange body. 30F and flange body 40F locking together at four gripping locations by screwing weld nuts 38 and bolts 42 together. Flange 110F of coupler member 102 corresponds to a joint plate.
[00163] [00163] A front end of the coupler member 102 described above is positioned further forward than the front end of the front side member 12. Specifically, as shown in Figure 9a in Figure 12, the outer panel 108 includes a portion of 102P projection that projects out in front of the 108F flange. A front end of the projection portion 102P is positioned further forward than the front end of the front side member 12. SPACER
[00164] [00164] Vehicle body front section structure 100 includes spacer 104 which is adjacent to front side member 12 and coupler member 102 respectively. The spacer 104 is formed, for example, in a vertically flattened hollow triangular column shape by joining several members formed from a sheet metal material. The spacer 104 protrudes outwardly from the front portion of the front side member 12 towards the outboard vehicle width direction. The spacer 104 is, for example, adjacent to the side face 12S2, that being a vehicle width direction outside the wall portion of the front side member 12, by, for example, welding or the like.
[00165] [00165] The spacer 104 includes a load transmission portion 106 angled so that a rear side faces more to the vehicle width direction inside than a front side. The load transmission portion 106 configures a vehicle width steering wall on the outside (rear side) of the spacer 104. Specifically, the spacer 104 is configured from main portions of an interior panel 112 which is adjacent to the front side member 12, and an outer panel 114 which is adjacent to the inner panel 112 and forms a closed cross-section with the inner panel 112. As shown in Figure 17, in plan view, the outer panel 114 extends. from a stiffness portion (a location installed with a partition 116), described later, of the coupler member 102, and reaches the same distance as the location of a joint between a rear portion of the spacer 104 and the side face 12S2 of the member front side 12.
[00166] [00166] The outer panel 114 is configured as a portion of the spacer 104 with high rigidity in relation to the rear load, for example, by configuring the outer panel 114 of a material with greater thickness, or with greater tensile strength, than the inner panel 112. Accordingly, in the present exemplary embodiment, the load transmitting portion 106 is primarily configured on outer panel 114.
[00167] [00167] A front side joint portion 106A is provided at a front end portion of the load transmitting portion
[00168] [00168] As illustrated in Figure 16 and Figure 17, the partition 116, which serves as a reinforcing member, is provided within the cross-section of the front portion 102F of the coupler member 102. The partition 116 is formed in a shape of hat, which opens towards the rear in the flat view. Specifically, partition 116 includes rear wall portion 116R which forms the bottom of the hat shape, a pair of arms 116A extending from both vehicle width steering ends of rear wall portion 116R towards the front. , and a pair of left and right front flanges 116F that extend from the front ends of both arms so as to distance themselves from each other in the vehicle width direction. The rear wall portion 116R is joined to an interior face (front face) of an interior panel portion 110 that forms the rear face 102B of the coupler member 102 by means such as welding.
[00169] [00169] The pair of front flanges 116F is joined to an inner face (rear face) of a portion of the outer panel 108 that configures the front portion 102F by means such as welding. More specifically, the front flange 116F in the interior vehicle width direction is adjacent to the interior face on a portion of the outer panel 108 that configures the projection portion 102P. The front flange 116F in the outer vehicle width direction is adjacent to the inner face on a portion of the outer panel 108 that forms a front portion of the curved face 102C.
[00170] [00170] The vehicle body front section structure 100 is then formed with a path along which a rear load inlet to a front end portion of the coupler member 102 passes through the bulkhead 116 and the transmission portion. of load 106 of spacer 104 and is transmitted to front side member 12. Enclosure 116 forms a reinforcing structure in one portion wherein front portion 102F of coupler member 102 transmits load to spacer 104. Enclosure 116 forms the stiffness portion at front portion 102F of coupler member 102.
[00171] [00171] The partition 116 can be understood as a portion of the spacer 104 (a front lateral extension portion of the load transmitting portion 106) which transmits load input to the projection portion 102P to the front side member 12 and is independent of the member coupler 102 which transmits load to upper skirt member 26. Front portion 102F of coupler member 102, partition 116 and spacer 104 can also be collectively understood as a member (angle) for transmitting rear load input in the direction of vehicle width outside the front side member 12 to the front side member 12.
[00172] [00172] Other configurations of the vehicle body front section structure 100, according to the present exemplary embodiment, including portions that are not illustrated, have basically the same configuration as the vehicle body front section structure 10, according to the first exemplary modality. Consequently, the vehicle body front section structure 100 enables basically the same advantageous effects to be obtained from the same operation as the vehicle body front section structure 10.
[00173] [00173] In the vehicle body front section structure 100, the load transmitting portion 106 of the spacer 104 is joined to the rear face 102B of the coupler member 102. The load can be transmitted, consequently, from the barrier Br to a side portion of the front side member 12 through the coupler member 102 (panel 116) and the spacer 104 from before the start of deformation of the coupler member 102. In particular, since the spacer 104 includes the load transmitting portion 106, as described above, when the collision load is inserted to the projection portion 102P of the coupler member 102 from the front, the load can be efficiently transmitted through the load transmitting portion 106 to the front side member 12. A bearing bend the vehicle width direction inside can be induced on the front side member 12 as the stress can be concentrated on the front side member 12 in the vicinity of a rear end of the t portion. 106 load transmission (on the P power unit side).
[00174] [00174] In addition, the projection portion 102P of the coupler member 102 is positioned heading further than the front end of the front side member 12, so the collision load consequently acts on the coupler member 102 before acting on the front side member 12 after the crash box 14 has been compressed. The projection portion 102P of the coupler member 102, that being a load inlet portion, is positioned more to the vehicle width direction outside than the front side member 12, so the collision load causes a moment acting in one direction bend the front side member towards the interior vehicle width direction. Bending of the front side member 12 towards the inward vehicle width direction is consequently promoted.
[00175] [00175] In the vehicle body front section structure 100, a stable displacement mode of car A relative to barrier Br in the vehicle width direction can therefore be achieved in a short time after the onset of a collision of small overlap, and this displacement can be further promoted.
[00176] [00176] The coupler member 102 and the load transmitting portion 106 may be prevented from unintentionally moving apart from each other due to the collision load, since the front end portion of the load transmitting portion 106 of the space - hook 104 is adjacent to the rear face 102B of the coupler member 102 (the rear wall portion 116R of the partition 116). In a comparative example in which the spacer 104 and the coupler member 102 are not joined together, there is a concern that noise is caused by an unintended interference between the coupler member and the load transmission portion 106 due to vehicle vibration. during a normal route. However, in the present exemplary embodiment, the front end portion of the load transmitting portion 106 of the spacer 104 is joined to the rear face 102B of the coupler member 102 (the rear wall portion 116R of the partition 116), as described above. . Consequently, there is no unintended interference between the coupler member and the load transmission portion 106 due to vehicle vibration during normal travel, which allows for the occurrence of noise caused by such interference.
[00177] [00177] In the fifth exemplary Modality, the spacer 104 is formed in a triangular shape in the plan view; however, the present invention is not limited thereto, and projection member shape definitions may be modified as appropriate. For example, the projection member can be formed into a trapezoid or a semicircle that projects towards the vehicle width direction outside in the plan view.
[00178] [00178] In the fifth Exemplary Modality, the crash box 14, which serves as a shock absorbing section, is attached to the front side member 12 of the front side member 12; however, the present invention is not limited thereto, and a shock absorbing section is provided integrally with a front portion of a front side member. In such cases, a front end portion of the coupler member is attached to a portion of the front side member further to the rear side than the shock absorbing section.
[00179] [00179] In the fifth exemplary Embodiment, the partition 116 is fixed within the cross-section of the front portion 102F of the hollow shape 102 as a reinforcing member, thereby reinforcing the front portion 102F; however, the present invention is not limited thereto, and a configuration can be made without a reinforcing member. In such cases, for example, a front portion of the coupling member may be formed thicker (the plate thickness of the material may be set thicker) than at other locations of the coupling member (at least one location adjacent to the front portion of the coupler member) thereby reinforcing the front portion of the coupler member. Furthermore, since the front portion of the coupler member is preferably configured with greater rigidity at least with respect to a load in the longitudinal direction,
[00180] [00180] In the fifth exemplary Modality, the vehicle width steering face on the outside of the front portion 102F of the coupling member 102 configures the curved face 102C that curves so that the rear side is positioned more towards the width direction of vehicle on the outside than the front side. However, the present invention is not limited thereto, and a configuration can be devised in which the vehicle width steering face on the outside of the front portion of the coupler member is continuous along the longitudinal direction or is angled so as to be oriented more towards the direction of vehicle width on the outside in progression towards the rear side.
[00181] [00181] In each of the exemplary embodiments described above, an explanation has been given in relation to the examples in which the vehicle body front section structure 10 includes the coupler member 46, 102 and the spacer 56, 104 on both la - from the vehicle width direction; however, the present invention is not limited thereto. For example, a configuration can be devised in which the coupler member 46, 102, and the spacer 56, 104 are provided on only one side in the vehicle width direction. In such cases, on the side on which the coupler member 46, 102 and spacer 56, 104 are not provided, a component mounted on a vehicle may, for example, double as a spacer, or another structure may be employed to react to the collision. overlay icons.
[00182] [00182] In each of the exemplary embodiments described above, an explanation has been given in relation to the examples in which the front flange 30 extends downward and supports the end.
[00183] [00183] Obviously, several modifications can be implemented within a range that does not depart from the spirit of the present invention.
