Side seal structure of vehicle {VEHICLE SIDE SILL STRUCTURE}
[13] The present invention relates to a side seal structure of a vehicle, and more particularly, to a side seal structure of a vehicle that enables proper deformation in response to a front collision, an offset collision, and a side collision of a vehicle.
[14] Since the vehicle is subject to various impacts from the outside when the vehicle travels, the vehicle body frame structure portion is basically formed to maintain a predetermined rigidity. In particular, a portion that allows deformation to absorb shock when subjected to overload, and a portion that prioritizes rigidity reinforcement to secure occupant space, such as a frame structure around the vehicle interior.
[15] By the way, the body frame structure part which forms the side part of a vehicle body is equipped with the roof rail of the upper part of a vehicle body, the side seal of the lower part of a vehicle body, the front pillar which connects them up and down, a center pillar, a rear pillar, etc. Usually, each of these members is formed so as to adopt a closed cross-sectional structure in which the cross-sectional structure forms a closed space, thereby enhancing the rigidity of each portion. Among these, the side seals, in particular, in the front-rear or offset collision of the vehicle, Since it is subjected to overload (compression load), it is necessary to sufficiently suppress the bending deformation and the buckling deformation of the side seal itself to achieve load distribution. In addition, when an overload in the vehicle width direction is received at the time of a side collision, it is desired to be able to control the bending mode (the way in which the side seal itself is bent) in the vehicle width direction.
[16] However, in the conventional side seal structure, for example, in JP-A-6-99851, in order to improve the rigidity at the inverse T-shaped coupling portion between the side seal and the center pillar bonded to the intermediate portion thereof, An inverted T-shaped pipe member that suppresses deformation of the same portion at the time of side collision is disposed in an inverted T-shaped space. In Japanese Patent Application Laid-Open No. 64-18784, a pipe member is attached between a plurality of bulkheads in a closed space continuous in the longitudinal direction of the side seal, thereby overloading the front and rear direction of the side seal (compression When load is applied, the load is distributed.
[17] For this reason, in the above-described conventional structure, only various countermeasures for stiffening are made, and in particular, proper deformation is not performed against side impact.
[18] An object of the present invention is to provide a side seal structure of a vehicle in which an appropriate deformation can be made particularly in response to a side collision.
[19] In order to achieve the above object, in the invention of claim 1, in the side seal structure of the vehicle, the side seal portion of the vehicle is provided with a side seal portion extending in the front and rear direction of the vehicle body to form a first closed cross-sectional shape. A center pillar which is coupled and extended upward, a pipe member which is installed to extend in the front and rear direction of the vehicle body inside the side seal portion, and a weak portion is formed at at least two locations of the side seal portion by sandwiching the intermediate portion; And a rain force member installed along the side part to cover the weak part and having a second closed cross-sectional shape in cooperation with the side part.

[12] 203: rear vertical column 303: rear quarter panel
[20] 1 and 2 show a vehicle body side skeleton structure 1 to which a side seal structure of a vehicle is applied as one embodiment of the present invention.
[21] The vehicle body side frame structure 1 includes a single side outer panel 2 that is continuously arranged over a portion of the vehicle interior and a trunk of an automobile (not shown), and an inner panel 3 composed of a plurality of constituent members is welded or the like. Are integrally joined together. In addition, although the vehicle body side frame | skeleton structure 1 of the left side is shown in FIG. 1, this vehicle body side frame | skeleton structure 1 has the vehicle body side frame structure (not shown) of the right-and-left symmetrical shape to this, and a vehicle interior facing part. By combining a plurality of skeletal structural members (not shown) arranged in the trunk opposing part, the engine room opposing part, and the like, the entire vehicle body skeleton structure of the passenger car shown in the drawing is formed.
[22] Here, the side roof rail (not shown) of the closed cross-sectional shape long in the vehicle body front-back direction X is formed by the upper horizontal part 201 and the side roof rail inner 301 of the side outer panel 2 here. do. Moreover, the front pillar (not shown) of the substantially closed cross-sectional shape extended in the up-down direction is formed by the front vertical column 202 of the side outer panel 2 and the vertical front pillar inners 302a and 302b. Moreover, the rear pillar (not shown) of the substantially closed cross-sectional shape extended in the up-down direction is formed by the rear vertical column 203 and the rear quarter panel 303 of the side outer panel 2. The side seal SS (refer FIG. 3) of the closed cross-sectional shape elongate in the vehicle body front-back direction X is a lower horizontal part (henceforth a side seal outer) 204 of the side outer panel 2, and a side seal inner ( The center pillar (refer to FIG. 4) CP formed of a 304 and coupled to an intermediate portion of the side seal SS may be installed at the center pillar portion 205 and the center pillar inner of the side outer panel 2. 306).
[23] In addition, each member mentioned above is shape | molded by the press work of a steel plate, respectively, and the side frame | skeleton structure (1) is made by joining together the some flange f which extends from the place of the periphery of these members, and the polymerization part of various shapes. Is formed.
[24] As shown in FIG. 2, FIG. 3, the side seal | sticker SS is each upper and lower flange f1, f2 of the side seal outer 204 and the side seal inner 304 which are lower horizontal parts of the side outer panel 2 Are joined to each other to form a first closed space e1 elongated in the front-rear direction X of the vehicle body (the paper vertical direction in FIG. 3). In addition, the first seal space e1 formed by the side seal outer 204 and the side seal inner 304 being coupled to each other to form a first closed cross-sectional shape is provided over the entire region in the front-rear direction X of the side seal SS. The reinforcement frame 4 is arranged.
[25] The reinforcement frame 4 is formed of the metal pipe member 5 and the rain force member 6 provided along the side portion 501 of the vehicle body outer side (right side in FIG. 3) of the copper pipe member 5.
[26] The pipe member 5 joins the front and rear brackets 7 and 8 to its front and rear ends, respectively, and a plurality of locations of the main part and the end flange f3 of each of the front and rear brackets 7 and 8 are provided with the side seal outer 204 and the side. Polymerization is carried out at the front and rear ends of the seal inner 304, respectively, and each polymerization portion is integrally joined. In addition, since the pipe member 5 is equipped with the front and rear brackets 7 and 8 at its front and rear ends, the pipe member 5 drills in the front and rear direction X when the pipe member 5 receives an overload in the front and rear direction X. Can be prevented. In addition, the front and rear brackets 7 and 8 may be provided as necessary in consideration of the degree of overload in the front and rear direction X acting on the pipe member 5.
[27] In the center portion of the side surface portion 501 of the pipe member 5, a recessed portion 9 is formed toward the outside of the vehicle while maintaining a predetermined distance d. The excavated portion 9 is formed with a groove depth h of about 1/6 of the inner diameter as viewed in the cross section of the pipe member 5, and enables the bending mode control (control) based on this. In addition, the middle part of the two hollowed parts 9 of the pipe member 5 is a site | part in which the lower end part of the center pillar CP and the side seal | sticker SS employ | adopt an inverted T-shaped coupling structure, By setting it in this way, As described later, the bending at the lower end of the center pillar is suppressed at the time of the side collision, and the bending at the two recessed portions 9 can be caused. In addition, since the predetermined distance d needs to control the seat position in accordance with the basic dimensions of the vehicle, that is, the vehicle dimensions, the occupant position, or the energy dissipation conditions, the numerical value needs to be set for each vehicle.
[28] The rain force member 6 has a length substantially the same as that of the pipe member 5, and is continuously polymerized on the side surface portion 501 of the pipe member 5 and welded at a plurality of locations. Further, the rain force member 6 has an outer side of the vehicle body such that the protruding end p has a space t with respect to the side seal outer 204 from the upper and lower joining portions 601 that polymerize with the side portions 501 of the pipe member 5. It has a convex bulge part 602 which protrudes toward the side. In addition, the smaller the space t is, the higher the strength against the side protrusion of the side seal SS is, but it is necessary to avoid the interference between the rain force member 6 and the side seal SS due to the production variation. About 5mm is suitable. Moreover, the rain force member 6 is provided with the up-and-down directing board parts 603 and 604 which extend in the up-down direction rather than the up-and-down end of the up-and-down junction part 601, These are formed by press molding of a steel plate.
[29] The upper direction plate part 603 of the rain force member 6 forms a vertical plate shape, and the bead 11 which extends in the up-down direction at the base end maintains the predetermined distance b along the front-rear direction X of the vehicle body. And formed in plural and the upper portion of these beads 11 forms a flange f4, and is fitted to the polymerization portion of each upper flange f1 of the same side seal outer 204 and side seal inner 304. It is joined integrally in a warped state.
[30] The lower directing plate portion 604 of the rain force member 6 forms a curved plate shape, and at its proximal end, a bead 11 extending in the vertical direction maintains a predetermined distance b along the front and rear direction X of the vehicle body. Lower ends of these beads 11 are bent in a more shorter shape, their ends form a flange f5, and the same portion of each lower flange of the side seal outer 204 and the side seal inner 304 is formed. It is joined integrally in the state stuck to the polymerization part of (f2). Here, the bead 11 is provided to improve the bending rigidity of the reinforcement member in the vehicle width direction, whereby the reinforcement member is displaced in the vehicle width direction when the vehicle travels to contact the side seal SS to generate noise. It is preventing. The shorter the predetermined interval b is, the shorter the rigidity of the reinforcement member in the vehicle width direction increases, but about 50 to 80 mm is appropriate because of the relationship with the welding pitch. In addition, in FIG. 3, the code | symbol W1 shows an arc welding point, the code | symbol W2 shows an indirect welding point, and the joining process is performed at each point of W1 and 2. As shown in FIG.
[31] In the reinforcement frame 4 shown to FIG. 2, FIG. 3, the rain force member 6 is joined continuously along the side part 501 of the outer side of the vehicle body of the pipe member 5. As shown in FIG. For this reason, when the pipe member 5 and the rain force member 6 cooperate, the 2nd closed cross-sectional shape which forms the 2nd closed space e2 can be formed, and the rigidity of the reinforcement frame 4 can be strengthened. In particular, the reinforcement member 6 covers the dents 9 formed at the two positions of the pipe member 5 with the legs installed, respectively, so that the rigidity against the compressive load of the same portion is almost the same as that of other portions. Can be maintained.
[32] As described above, the side seal SS forms a first closed cross-sectional shape with the side seal outer 204 and the side seal inner 304, and forms a first closed space e1 that is long in the front and rear direction X of the vehicle body, thereby providing basic rigidity. Can be secured. Furthermore, since the pipe member 5 and the rain force member 6 constituting the reinforcing frame 4 in the first closed space e1 are joined to form a second closed cross-sectional shape, the second closed space e2 is formed. In addition, it is possible to function to sufficiently suppress the buckling deformation even against excessive compression load.
[33] As described above, it is assumed that a passenger car manufactured by using the vehicle body side frame structure 1 in which the reinforcing frame 4 is added in the frame of the side seal SS has crashed at the front or at the time of driving. At this time, an overload in the front-rear direction is applied to the front end of the side seal SS, but even when subjected to this excessive compressive load, firm reinforcement by the pipe member 5, which is a round pipe, is possible. Furthermore, in addition to the rigidity of the side seal outer 204 and the side seal inner 304 forming the first closed space e1, the rigidity of the reinforcement frame 4 forming the second closed space e2 is excessive. Compressive load is distributed throughout the side seal (SS), that is, distributed to the rear pillar side of the vehicle body and transmitted.
[34] In addition, since the reinforcement member 6 is covered in the state where the legs are placed in the two recessed portions 9 of the five member 5, the stiffness to the buckling deformation of the same portion is almost the same as that of other portions. It can be kept at the same level and can prevent this area from prompting buckling.
[35] In addition, although the front collision was demonstrated here, in the rear collision, it reverses back and forth, and almost the same deformation | transformation operation is performed, and almost the same effect is acquired.
[36] On the other hand, suppose that a passenger car has laterally collided with the middle part of the side seal SS at the time of running.
[37] The middle part of the side seal SS is a site | part which the lower end part of the center pillar CP is integrally couple | bonded, and employ | adopts the inverse T-shaped coupling structure, As shown in FIG. 4, the pipe member 5 of this site | part 5 ), Two dents 9 are provided at predetermined intervals d.
[38] For this reason, when the overload F of the vehicle width direction Y is applied to the intermediate part of the side seal SS, at this time, the side seal outer 204 will only crush space T (refer FIG. 3).
[39] Subsequently, the reinforcing frame 4 deforms relatively easily compared with the compressive load by the load from the side. At this time, the pipe member 5 deform | transforms to the vehicle body center side (lower side in FIG. 4) starting from the two recessed parts 9, and the side seal inner 304 is also deformed.
[40] In this way, when the bulging portion 602 of the rain force member 6 is moved outwardly (outwardly), energy is efficiently transferred to the stiffening reinforcement frame 4 faster than after the side impact, and energy is absorbed. Can function.
[41] In addition, in the side impact, the pipe member 5 can be bent from two points 9 without causing the pipe member 5 to be bent to one point, so that the middle portion of the side seal SS and the center pillar CP can be caused. Can significantly reduce the amount of intrusion (strain) and the speed of intrusion into the vehicle interior, that is, it is possible to create a deformation mode as desired, and to exhibit the bending mode control (control) function. Can improve the safety.
[42] In addition, when the intermediate portion of the side seal SS is subjected to a side impact, the bulging portion 602 of the rain force member 6 and the pipe member 5 can absorb the overload during side impact in turn, thereby absorbing shock. Can improve.
[43] In addition, the side seal SS of FIG. 1 forms a first closed space e1 elongated in the vehicle body front-rear direction X by the side seal outer 204 and the side seal inner 304, and a reinforcement frame ( Since 4) is disposed, the structure is simplified compared with the conventional structure. In connection with this, the number of parts, the number of welding process steps, the metal mold | die and the installation are simplified, and manufacturing cost can also be reduced. In addition, the overall thickness of the side seal outer 204 and the side seal inner 304 forming the outer surface can be made thinner, and the overall weight can be reduced.
[44] In FIG. 5, the side seal SSa in the vehicle body side frame structure 1 (not shown) which applied the side seal structure of the vehicle as 2nd Embodiment is shown.
[45] This side seal SSa is compared with the side seal SS used by the vehicle body side frame structure 1 of FIG. 1, and the inside and outside of the pipe member 5a and the rain force member 6a which comprise the reinforcement frame 4a. Since the same configuration is adopted except that the position (left and right position in Fig. 5) relationship is reversed, the description is omitted.
[46] The side seal SSa of FIG. 5 forms the first closed space e1 by the side seal outer 204 and the side seal inner 304, and reinforces the frame 4a in the first closed space e1. It is arrange | positioned over the whole of the direction X (the paper vertical direction in FIG. 5).
[47] The reinforcement frame 4a is formed of the pipe member 5a and the rain force member 6a provided along the side portion 502 of the inside of the vehicle body (left side in FIG. 5) of the pipe member 5a. The pipe member 5a is integrally joined to the front and rear ends of the side seal outer 204 and the side seal inner 304 with a front and rear bracket (not shown) between them. In the central portion of the side surface portion 502 of the pipe member 5a, two recessed portions 9a are formed toward the center of the vehicle interior while maintaining a predetermined distance d (see Fig. 6). Control is enabled.
[48] The rain force member 6a protrudes toward the inside of the vehicle body, with an up and down joint 601a welded to the side surface portion 502 inside the vehicle body of the pipe member 5a, and the protruding end p intersects the space t1. The convex bulge part 602a which opposes the side seal inner 304 is provided, and the up-and-down direction board parts 603a and 604a are provided. The top and bottom directing plate portions 603a and 604a of the rain force member 6a are provided with beads 11 at the proximal ends of the vertical plates. The upper portion of the upper director plate portion 603a forms a flange f4 and is integrally joined to the upper flange f1 of the side seal outer 204 and the side seal inner 304. At the proximal end of the lower directing plate portion 604a, a stepped bend is formed from the lower end of the bead 11, and the flange f5 at the front end of each of the lower flanges of the side seal outer 204 and the side seal inner 304 ( f2).
[49] In this way, it is assumed that a passenger car using the vehicle body side frame structure 1a in which the reinforcing frame 4a is added in the frame of the side seal SSa has collided with the front surface or offset.
[50] In this case, the side seal SSa shown in FIG. 5, FIG. 6 is the side seal outer 204 and side seal which form the 1st closed space e1 like the case of the side seal SS of FIG. In addition to the rigidity of the inner 304, the rigidity of the reinforcing frame 4a forming the second closed space e2 distributes the excess compressive load throughout the side seal SSa, i.e., at the rear of the vehicle body. It can be distributed and delivered to the rear pillar side. At this time, since the reinforcement member 6 is covered in the bridged portion 9a formed in two places in the bridge state, the same part is suppressed from buckling faster, and the stiffness to the compressive load is almost equal to that of other parts. You can keep it at the level.
[51] On the other hand, in the case where the passenger car laterally collides with the middle portion of the side seal SSa while driving, when the overload F in the vehicle width direction Y is applied to the middle portion of the side seal SSa, first, the side seal outer 204 is crushed, and then an overload is applied to the reinforcing frame 4a (see FIGS. 5 and 6). In this case, only the space t1 is deformed on the vehicle body center side (left side in FIG. 5) with the pipe member 5a starting from the two recessed portions 9a, and the protruding end p of the bulging portion 602a is deformed. It is pushed into this side seal inner 304.
[52] The side seal SSa in the vehicle body side frame structure 1a (not shown) shown in FIG. 5 has the same effect as the vehicle body side frame structure 1 of FIG. 1. In particular, since the bulging portion 602a of the rain force member 6a is the vehicle interior side (inward), in this case, the bulging portion 602a is attached to the bottom seal inner 304 by the bottom of the load-bearing member. Can increase the weight. Moreover, the subsequent deformation speed and deformation amount can be greatly reduced, that is, the bending mode control (control) function can be exhibited, and the safety of the occupant can be improved in this respect. In addition, when the overload F at the side impact is large, the bulge portion 602a and the pipe member 5a of the rain force member 6a can absorb the overload F in turn, thereby providing a shock absorbing function. It can fully improve.
[53] As described above, the side seal structure of the vehicle of the present invention is applied to the vehicle body side skeleton structure 1 of the passenger car, but can be applied to a vehicle having other side seals, and in this case, the vehicle body side skeleton of FIG. The effect similar to the structure (1) is obtained.
[54] As described above, in the structure of the present embodiment, the rigidity can be strengthened so as to sufficiently suppress the buckling deformation at the weak portion when the first closed cross-sectional shape portion receives the compressive load during the front collision or the offset collision. In addition, the deformation amount of each of the weak parts of the pipe member and the rain force member covering the pipe member can be suppressed at the time of side impact, and the bending mode control (control) function starting from the weak parts can be ensured. In addition, since the structure of the present embodiment is simplified, the number of parts can be reduced, the number of welding operation steps can be reduced, the mold and equipment can be simplified, and the manufacturing cost can be reduced.
[55] In 1st Embodiment, since the 2nd closed cross-sectional shape is formed in the outline convex shape which ran out toward the vehicle body outer side, in particular, the protruding end of the outline convex shape receives an overload from the early stage at the time of side collision, and deform | transforms. Since the energy absorption can be started at the beginning, the shock absorption function can be suitably improved.
[56] In addition, when the second closed cross-sectional shape is formed into a roughly convex shape projecting toward the inside of the vehicle body as in the second embodiment, the side seal portion may be deformed in particular by the side collision. At this time, the side seal portion is attached to and supported on the inner wall surface inside the vehicle body, whereby the shock absorbing function can be improved.
