    (□ 4 / FRONT STRUCTURE OF VEHICLE COMPRISING A BUMPER WITH A PROTUBERANCE ARRANGED TO DEFORM DURING AN IMPACT SHOCK.
    ©) The invention aims to remove, at the time of an offset shock, a deformation of a bumper member and prevent excessive deformation of a side member. It offers a structure including: a side member (2); a bumper member (3) arranged linearly at a frontmost end of the vehicle, a vehicle rear side of the bumper member being connected to the side member; and a front side organ extension (4).
    An protruding portion (31) is provided at both ends of the bumper member, a protrusion (5) is arranged on the internal side of the protruding portion, a flat portion (52) is formed on an end portion end on the internal vehicle side of the protrusion, and the flat portion and the side member extension are arranged so as to overlap in the longitudinal direction of the vehicle.
    FRONT VEHICLE STRUCTURE
    The present invention relates to a front structure of a vehicle.
    In a conventional vehicle front structure, a bumper member connected to front end portions of side members is arranged in the vehicle width direction, and extension portions extending inwardly. outside in the direction of the vehicle width are provided at both ends in the direction of the vehicle width of the bumper member. Certain vehicles comprising this type of vehicle front structure are configured so that, in an impact mode in which an impact load from a frontal impact is applied only to the extension parts of the barrier member impact load is transmitted to the side members through the extension parts.
    For example, in a front structure of the patent literature 1 vehicle, a protruding front protruding forward, and a rear protrusion which comes into contact with a front side member at the time of a small overlapping shock, are provided in an extension part of a bumper reinforcement, which is on the outer side of a support position of the front side member. Thus, an input impact charge is absorbed by being transmitted to the front side member through the protuberance.
    [Patent literature 1] JP 2016-078 492 A.
    However, in the aforementioned conventional vehicle front structure, the rear protrusion has a triangular section including an inner end end portion, and is arranged so as to protrude towards the rear of the vehicle. Consequently, at the time of an offset shock in which the impact load is applied only to the extension part, the extension part is pushed towards the rear of the vehicle and deforms and can therefore be unable to transmit the impact load to the front side member. In addition, in the conventional vehicle front structure, a fragile part must be provided in the vehicle front part of the front side member, and at the time of an impact, the fragile part of the front side member must be pushed and deformed by the inner tip end portion of the rear protrusion to absorb the shock load. Hence, a complexification of the structure and an increase in costs.
    The present invention has been made in view of the above and aims to provide a front structure of a vehicle which, at the time of an offset impact on a bumper member, eliminates a deformation of the bumper member by bringing a protrusion into contact with a side face of a side member together with a deformation of the bumper member, and prevents excessive deformation of the side member towards the internal side of the vehicle by strengthening the side organ with front side organ extension, so that the protuberance is free to exercise its full function, and the ability to reduce damage from shock can be enhanced.
    To solve the above problems of the conventional technique, the present invention is a vehicle front structure including: a side member extending in a longitudinal direction of the vehicle, and arranged on both sides of a vehicle; a bumper member extending in a vehicle width direction and arranged linearly at a frontmost end of the vehicle, a vehicle rear side of the bumper member being connected to the side organ; and a front side member extension extending in a vertical direction of the vehicle, and attached to an end end portion of the side member, the bumper member having a point of curvature on the outer side in a vehicle width direction, and a projecting portion protruding outward in the vehicle width direction and extending obliquely towards the rear of the vehicle from the point of curvature being provided at both ends in the direction of the vehicle width of the bumper member, in which: a protrusion extending towards the side member is arranged on an internal side in the direction of the vehicle width of the protruding portion, a planar portion opposite a side face portion of the outer vehicle side of the side member being provided on a tip end portion of the inner vehicle side of the protrusion; and the planar portion of the protrusion and the front side member extension are arranged to overlap in the longitudinal direction of the vehicle.
    As described above, the vehicle front structure of the present invention includes: a side member extending in a longitudinal direction of the vehicle, and arranged on both sides of a vehicle; a bumper member extending in a vehicle width direction and arranged linearly at a frontmost end of the vehicle, a vehicle rear side of the bumper member being connected to the side organ; and a front side member extension extending in a vertical direction of the vehicle, and attached to an end end portion of the side member, the bumper member having a point of curvature on the outer side in a vehicle width direction, and a projecting portion protruding outward in the vehicle width direction and extending obliquely towards the rear of the vehicle from the point of curvature being provided at both ends in the direction of the vehicle width of the bumper member. A protrusion extending towards the side member is arranged on an inner side in the direction of the vehicle width of the protruding portion, a planar portion opposite to a side face portion of the outer vehicle side of the member from the side being provided on an end end portion of the vehicle internal side of the protrusion; and the planar portion of the protrusion and the front side member extension are arranged to overlap in the longitudinal direction of the vehicle.
    Accordingly, in the vehicle front structure of the present invention, at the time of a staggered impact which is a mode in which an end portion on one side of the vehicle front portion is impacted, and the protruding portion of the bumper member on the impacted side flexes towards the rear of the vehicle, the planar portion of the protrusion comes into contact with the side face portion on the outer vehicle side of the side member together with a deformation of the bumper member. Thus, the protuberance is interposed as a support between the protruding portion of the bumper member and the side face portion of the side member, and can suppress deformation of the bumper member. Likewise, by suppressing deformation of the bumper member, deformation of the side member towards the vehicle interior can be prevented, and damage can be reduced. In addition, in the vehicle front structure of the present invention, the front side member extension is provided in the side member so as to correspond to the planar portion of the protrusion, whereby the side member is reinforced by the front side organ extension. Thus, when the protrusion comes into contact with the side member, excessive deformation of the side member towards the internal side of the vehicle can be prevented, and since the protrusion is free to fully exercise its function, the ability to reduction of damage from shock can be enhanced.

    Hereinafter, the present invention will be described in detail based on an embodiment illustrated in the drawings.
    Figures 1 to 5 illustrate a vehicle front structure of the embodiment of the present invention. Note that in the drawings, the arrow Fr indicates the front of the vehicle, the arrow O indicates the external side of the vehicle, and the arrow U indicates the upper direction of the vehicle. Also, the arrow X indicates the direction of the vehicle width, and the arrow Y indicates the longitudinal direction of the vehicle.
    As illustrated in FIGS. 1 to 5, a front part of vehicle 1 to which a structure of the embodiment of the present invention is applied mainly comprises: side members (front side members) 2 which extend in the vehicle longitudinal direction, and are respectively arranged on the two side parts of the vehicle; a bumper member 3 which extends in the vehicle width direction is arranged linearly at a frontmost end of the vehicle, a rear vehicle side of the bumper member 3 being connected to side organs 2; and front side member extensions 4 which extend in the vertical direction of the vehicle, and are attached to end end portions of the side members 2. A connecting portion 21 with the barrier member shock 3 is formed on a front end part of each of the side members 2, and connecting portions 32 with the side members 2 are formed in parts of the bumper member 3 on external sides d 'a middle part of the rear side of the vehicle of the bumper member. In other words, the side member 2 and the bumper member 3 are connected at the level of the two right and left connecting portions 21, 32.
    The bumper member 3 of the embodiment includes: a middle part in the direction of the vehicle width having a linear structure; and bending points (bending points) P on external sides in the direction of the vehicle width of the middle part. In addition, a protruding portion 31 protruding outward in the direction of the vehicle width, and extending over a predetermined length while being inclined at a predetermined arrow angle Θ (for example, 30 °) from the bend point P towards the rear of the vehicle, is provided on both ends in the direction of the vehicle width of the bumper member 3. The bend point P is positioned on the outer side of the vehicle connecting portion 32 with the side member 2, at about the same distance as the longitudinal width of the bumper member 3.
    As illustrated in Figures 1, 2 and 4, protrusions 5 extending respectively to the side members 2 on both the right and left sides are arranged on the inner side in the direction of the vehicle width of the portions protruding 31 in the bumper member 3 of the embodiment, and each protuberance 5 is formed in a substantially rectangular box structure in a plan view. The protrusion 5 also comprises: an arrangement portion 51 whose side of the base end portion 5a is arranged by being fixed to an inner wall face of the protruding portion 31 of the bumper member 3; and a planar portion 52 whose end end portion side 5b is arranged near a side face portion 2a of the vehicle external side of the side member 2, and is opposite and parallel to the portion of side view 2a. The flat portion 52 of the protrusion 5 and the front side member extension 4 are arranged so as to overlap in the longitudinal direction of the vehicle. In addition, normally, the flat portion 52 of the protuberance 5 is not in contact with the side face portion 2a of the vehicle external side of the side member 2, and a spacing c is formed between the planar portion 52 and the side face part 2a. The spacing c is provided to prevent the protrusion 5 from hindering a deformation of the side member 2, when the bumper member 3 in its entirety is pushed towards the rear of the vehicle, at the time of an impact total face (a total overlap shock) of the front part of vehicle 1. This is due to the fact that at the time of a total face impact of the front part of vehicle 1, the protruding portions 31 on the two parts d end of the bumper member 3 does not bend towards the rear of the vehicle, and the protrusions 5 therefore do not come into contact with the side face portions 2a of the vehicle external side of the side members 2 .
    As illustrated in Figures 2 and 4, in the protrusion 5 of the embodiment, a rear end portion 51a of the arrangement portion 51 on the protruding portion 31 is created in a shape which overlaps the planar portion 52 of the protrusion 5. The rear end portion 51a of the arrangement portion 51 is arranged to enter a zone in a vehicle longitudinal direction of the planar portion 52 in a side view of the vehicle. In addition, the protrusion 5 is formed so that a longitudinal length L1 of the flat portion 52 on the internal side of the vehicle is greater than a longitudinal length L2 of the arrangement portion 51 on the external side of the vehicle (Ll > L2). With this arrangement, at the time of an offset shock when the protruding portions 31 on end parts of the bumper member 3 receive a load in bending mode, and the load is applied in an internal horizontal direction vehicle, the flat portion 52 of the protrusion 5 receives the horizontal load to prevent deformation of the protruding portion 31 and other parts.
    Also, as illustrated in FIGS. 2 and 4, an internal face 5c on the front side of the vehicle of the protrusion 5 has a curved portion 53 curving towards the rear of the vehicle, and the curved portion 53 curving gently from the arrangement portion 51 on the external side of the vehicle towards the flat portion 52 on the internal side of the vehicle. By providing the curved portion 53, the area of the planar portion 52 positioned on the side of the tip end portion 5b of the protrusion 5 can be widened. Thus, even if the protuberance 5 is designed in a compact manner, a sufficient contact area of the planar portion 52 on the side face portion 2a of the vehicle external side of the side member 2 can be ensured.
    In addition, an external face 5d of the rear vehicle side of the protrusion 5 is formed in a linear plane inclined towards the rear vehicle side, from the rear end portion 51a of the arrangement portion 51 on the protruding portion 31 from the bumper member 3 towards the flat portion 52 of the protuberance 5. By creating the external face 5d of the rear side of the vehicle of the protuberance 5 in such a form, the resistance of the protuberance 5 facing a load, resulting from an offset shock, from a forward oblique direction can be increased, and a deformation of the protruding portion 31 of the bumper member 3 by the protuberance 5 is eliminated.
    At the same time, as illustrated in FIG. 4, a space S to avoid interference between the protuberance 5 and peripheral parts at the time of an impact is provided between the internal part of the vehicle of the protuberance 5 and the middle part. linear of the bumper member 3, and between the vehicle front side of the protrusion 5 and the vehicle rear side of the bending point P. Consequently, an impact load from the protruding portion 31 of the the bumper member 3 is transmitted to the side member 2 through the protuberance 5 without being hindered, since interference between the protuberance 5 and peripheral parts is prevented by the space S. The spacing between the internal part of the vehicle of the protrusion 5 and the linear middle part of the bumper member 3 is fixed to 1/3 of the longitudinal length of the bumper member 3.
    In the front part of vehicle 1 of the embodiment, the flat portion 52 of the protuberance 5 and the extension of the front side member 4 are arranged so as to overlap in the longitudinal direction of the vehicle, as illustrated in FIG. figure 4.
    For this reason, the side member 2 positioned opposite the flat portion 52 of the tip end portion 5b of the protrusion 5 is reinforced by the extension of the front side member 4. This eliminates deformation excessive of the side member 2 towards the internal side of the vehicle, at the time of an offset impact in which the planar portion 52 of the protuberance 5 comes into contact with the side face part 2a of the side member 2 .
    Furthermore, as illustrated in Figures 2 to 5, the front side organ extension 4 has an upper extension 41 extending in the upper direction of the vehicle on the upper side of the vehicle, and a lower extension 42 s extending in the lower direction of the vehicle on the lower side of the vehicle. The upper extension 41 and the lower extension 42 are formed so as to have a substantially U-shaped section whose opening is directed towards the internal side of the vehicle, and are connected so that an upper end portion of the lower extension 42 is arranged inside a lower end portion of the upper extension 41. In addition, the upper extension 41 is arranged and connected to an upper end end face of the side member 2, and an outer face of the lower extension 42 (front side member extension 4) and a side face portion 2b on the internal vehicle side of the side member 2 are in contact with each other. In other words, the lower extension 42 of the extension of the front side member 4 is arranged in the part on the internal side of the vehicle of the side member 2 on which the planar portion 52 of the protrusion abuts. 5. Thus, the side member 2 is less likely to be deformed by an impact, and a bending of the bumper member 3 is eliminated.
    In addition, as illustrated in Figures 2, 4 and 5, the upper extension 41 and the lower extension 42 are arranged in parts of the front side organ extension 4 on upper and lower sides of the side member 2. An upper and lower pair of fixing brackets 6, 7 is arranged so as to be spaced in the vertical direction of the vehicle, in the upper extension 41 and the lower extension 42. The parts of right and left end of the bumper member 3 are both fixed to a lower part of the upper extension 41 and an upper part of the lower extension 42 by means of the upper and lower pair of brackets fixing 6, 7. Consequently, the upper and lower pair of fixing brackets 6, 7 have L-shaped sections including vertical parts 6a, 7a attached to front faces of the upper extension 41 and of the lower extension 42, and horizontal pieces 6b, 7b attached to the x two rear ends of the middle part in the direction of the vehicle width of the bumper member 3.
    In other words, in the front part of vehicle 1 of the embodiment, the bumper member 3 is attached to the upper extension 41 and to the lower extension 42 of the side member extension front 4. Thus, the load of an offset and similar shock when the protuberance 5 comes into contact with the side member 2 is distributed towards the front side member extension 4, by means of the bumper 3.
    In the following, a description will be given of an operation of the vehicle front structure of the embodiment, at the time of an offset impact on the vehicle front part 1.
    When an impact load has entered an end portion on one side of the bumper member 3, and the protruding portion 31 at the end portion of the bumper member 3 is pushed towards the rear of the vehicle, the flat portion 52 of the internal side of the vehicle of the protuberance 5 formed on the internal side of the protruding portion 31 comes into contact with the side face portion 2a of the external side of the vehicle. the side member 2. From there, the impact load entered on the end portion on one side of the bumper member 3 is transmitted to the side member 2 through the protrusion 5 , and is also distributed to the extension of the front side member 4. Thus, the end part of the bumper member 3 and the side member 2 do not flex in the passenger compartment, but are deform in a cushioned manner. At the same time, the protuberance 5 does not fully deform, and only the point of contact with the side member 2 and the peripheral parts deform.
    Note that at the time of a total overlap impact of the front part of the vehicle 1, the protruding portions 31 on the two right and left ends of the bumper member 3 do not bend towards the rear of the vehicle . In addition, since the spacing c is formed between the flat portion 52 of the protuberance 5 and the side member 2, the middle part in the direction of the vehicle width of the bumper member 3 and the side member 2 deforms while moving towards the rear of the vehicle, without bringing the flat portion 52 of the protuberance 5 into contact with the side face portion 2a of the vehicle external side of the side member 2.
    Thus, the vehicle front structure of the embodiment of the present invention includes: the side member 2 which extends in the vehicle longitudinal direction in the vehicle front part 1, and is arranged in the two side parts of the vehicle ; a bumper member 3 which extends in the direction of the vehicle width, and is arranged linearly at a frontmost end of the vehicle, a vehicle rear side of the bumper member 3 being connected to the side organs 2; and the front side member extensions 4 which extend in the vertical direction of the vehicle, and are fixed to end end portions of the side members 2. The bumper member 3 has points of curvature P on the outer sides in the direction of the vehicle width, and the protruding portions 31 protruding outward in the direction of the vehicle width and extending obliquely towards the rear of the vehicle from the points P curvature are provided at both ends in the direction of the vehicle width. In addition, the protrusion 5 extending towards the side member 2 is arranged on the internal side in the direction of the vehicle width of the protruding portion 31, the tip end portion 5b on the internal side of the vehicle the protrusion 5 has the flat portion 52 opposite the side face portion 2a of the vehicle external side of the side member 2, and the planar portion 52 of the protrusion 5 and the front side member extension 4 overlap in the vehicle longitudinal direction.
    Thus, in the vehicle front structure of the present invention, at the time of an offset impact which is a mode in which an end portion on one side of the vehicle front portion 1 is impacted, and the protruding portion 31 of the bumper member 3 on the impacted side bends towards the rear of the vehicle, the protrusion 5 moves towards the side of the side member 2 together with a deformation of the bumper member shocks 3, and the flat portion 52 comes into contact with the side face part 2a of the external vehicle side of the side member 2. Consequently, in the structure of the present invention, the protuberance 5 is interposed as a support between the protruding portion 31 of the bumper member 3 and the side face part 2a of the side member 2, and can suppress bending of the bumper member 3, for example. Also, by suppressing deformation of the bumper member 3, deformation of the side member 2 towards the vehicle interior can be prevented, and damage can be reduced. In addition, in the vehicle front structure of the present invention, the front side member extension 4 is formed in the side member 2 so as to correspond to the flat portion 52 of the protrusion 5, whereby the the side member is reinforced by the extension of the front side member 4. Thus, when the protuberance 5 comes into contact with the side member 2, excessive deformation of the side member 2 towards the internal side of vehicle can be prevented, and since the protrusion 5 is free to fully exercise its function, the ability to reduce damage from impact can be further enhanced.
    In the vehicle front structure of the embodiment, the point of curvature P of the bumper member 3 is positioned on the external side of the vehicle rather than the connecting portion 32 with the side member 2. Thus, the length of the bumper member 3 in the longitudinal direction of the vehicle can be reduced, and the vehicle can be reduced in size. In addition, in the structure of the embodiment, at the time of an impact on the front part of the vehicle 1, a deformation of the bumper member 3 at the point of curvature P by the side member 2 is less likely to be embarrassed. Thus, the impact load can be absorbed more effectively.
    In addition, in the vehicle front structure of the embodiment, the protrusion 5 is created in a shape such that the rear end portion 51a of the arrangement portion 51 on the protruding portion 31 overlaps the planar portion 52 of the protuberance 5 in the longitudinal direction of the vehicle. Consequently, the rear end portion 51a of the arrangement portion 51 enters an area in the vehicle longitudinal direction of the planar portion 52 in a side view of the vehicle. Thus, even at the time of an offset shock when the protruding portions 31 on the end portions of the bumper member 3 receive a bending load, and the load is applied in an internal horizontal direction of the vehicle, the flat portion 52 of the protrusion 5 can receive the horizontal load, whereby a deformation of the bumper member 3 including the protruding portion 31 can be safely prevented.
    In the vehicle front structure of the embodiment, the curved portion 53 curving towards the rear of the vehicle is formed in the internal face 5c of the vehicle front side of the protrusion 5. Thus, the area of the flat portion 52 of the protrusion 5 can be widened, and even if the protrusion 5 is designed to be compact, a sufficient contact area of the planar portion 52 on the side face part 2a of the side member 2 can be ensured. This can remove a deformation of the bumper member 3, and allows the protuberance 5 to exercise its function stably.
    In the vehicle front structure of the embodiment, the outer face 5d of the vehicle rear side of the protrusion 5 is formed in a linear plane inclined towards the vehicle rear side, from the rear end portion 51a of the portion d arrangement 51 on the protruding portion 31 towards the planar portion 52 of the protuberance 5. Thus, the resistance of the protuberance 5 against a load, resulting from an offset shock, from a forward oblique direction can be increased, and the protuberance 5 can more effectively remove a deformation of the protruding portion 31 of the bumper member 3.
    In addition, in the vehicle front structure of the embodiment, the outer face of the lower extension 42 configuring the front side organ extension 4 and the side face portion 2b of the vehicle internal side of the side member 2 are arranged in mutual abutment. Thus, the side member 2 is less likely to be deformed by an impact than in a conventional structure, and a bending of the bumper member 3 can be suppressed reliably.
    In the vehicle front structure of the embodiment, the upper and lower pair of mounting brackets 6, 7 is arranged so as to be spaced in the vertical direction of the vehicle, in parts of the side member extension front 4 on upper and lower sides of the side member 2. The left and right end portions of the bumper member 3 are both attached to the front side member extension 4, by through the upper and lower pair of mounting brackets 6, 7. Thus, a load applied when the protrusion 4 comes into contact with the side member 2 can be distributed towards the front side member extension 4 through the bumper member 3, whereby deformation of the side member 2 can be suppressed, and deformation in the vehicle interior can be suppressed effectively.
    Although the embodiment of the present invention has been described, the invention is not limited to the above embodiment, and various modifications and various changes can be made based on the technical concept of the invention .
    For example, although the protrusion 5 of the above embodiment is formed into a box structure, it may have a U-shaped section with an open bottom side. Likewise, the protrusion 5 need not necessarily be hollow, and a honeycomb structure or the like to enhance stiffness can fill the interior of the protrusion.
