<First Embodiment>
FIG. 1 is an external view from the rear right side of a vehicle to which a vehicle body structure according to an embodiment of the present invention is applied. The vehicle 1 of this embodiment is a four-wheel passenger car. The vehicle 1 is a five-door vehicle having left and right front doors, left and right rear doors, and a tailgate on the rear end surface. The left and right rear doors are slide doors, and the right rear slide door 13 is shown in FIG. Note that the sliding door may be on either one of the left and right rear doors.

  Here, an example in which the structure of the present invention is applied to the periphery of the right rear door will be described. However, the structure may be applied to other parts such as the vicinity of the left rear door, and the right rear door and the left rear door may be applied. You may apply to several site | parts, such as each periphery.

  The vehicle body 10 of the vehicle 1 includes an outer panel 11 that forms the outer surface of the right rear portion of the vehicle body 10. The outer panel 11 is a metal plate-like member, for example, and has a vertically long shape as a whole in the present embodiment, and its lower portion is formed in an arc shape along the contour of the rear wheel. A window frame portion 113 that forms a window is provided on the upper portion.

  A slide rail 12 is provided on the outer panel 11 so as to extend substantially horizontally in the vehicle front-rear direction. The slide rail 12 is made of metal, for example, and is a member having higher rigidity than the outer panel 11 in this embodiment. The slide rail 12 guides the slide door 13 so that it can be opened and closed. FIG. 1 shows a state in which the slide door 13 is closed.

  Please refer to FIG. 2 together with FIG. FIG. 2 is a right side view of the vehicle body 10 and partially shows a rear portion (near the rear wheel) of the vehicle body 10.

  The outer panel 11 has a bead 111 that is formed by bending and forming the constituent members of the outer panel 11. This bead 111 is provided to improve designability or rigidity. In the present embodiment, the beads 111 protrude outward in the vehicle width direction and extend in the vehicle front-rear direction. Such a bead 111 can improve the design of the rear wheel above for decoration purposes. For the purpose of rigidity, the rigidity of the outer panel 11 above the rear wheel can be improved. In particular, in the case of the present embodiment, the bead 111 is formed along the slide rail 12, so that the periphery of the slide rail 12 is provided. The rigidity of can be improved. The form of the bead 111 is not limited to that of the present embodiment, and may be other forms such as a form protruding inward, a form extending inclined from the horizontal, or a curved form. Moreover, the structure which does not provide the bead 111 is also employable.

  3 and 4 are referred to together with FIG. FIG. 3 shows the right rear portion of the vehicle body 10 and shows a state where the outer panel 11 is removed from the state shown in FIG. 4 shows a state in which reinforcing members 17 and 18 (to be described later) are removed from FIG.

  The vehicle body 10 includes an inner panel 14 provided on the inner side in the vehicle width direction of the outer panel 11 and a wheel house 15 provided to be spaced downward from the inner panel 14.

  The inner panel 14 is, for example, a metal plate-like member, and has a substantially rectangular shape as a whole in the present embodiment. Further, the inner panel 14 is provided with a window frame portion 141 at a position overlapping the window frame portion 113 of the outer panel 11 when viewed from the vehicle width direction. The wheel house 15 is formed, for example, by bending a metal plate-like member, and the upper part is substantially parallel to the inner panel 14, but the lower part has an arc shape along the outer periphery of the rear wheel. And it extends in the vehicle width direction so as to cover the upper part of the rear wheel.

  The wheel house 15 is provided at a position spaced downward from the inner panel 14 when viewed from the vehicle width direction. Further, the inner panel 14 and the wheel house 15 are provided apart from each other in the vehicle front-rear direction, and are connected by pillar component members 21 and 22 that extend in the vertical direction. Therefore, a gap 16 is formed between the inner panel 14, the wheel house 15, the pillar component member 21, and the pillar component member 22. A configuration in which the inner panel 14 extends so as to fill the gap 16 can also be adopted. However, since the material of the inner panel 14 can be reduced by providing the gap 16, the vehicle 1 can be reduced in weight or cost.

  When such a gap 16 is provided, the rigidity may decrease in the vehicle front-rear direction center, but in this embodiment, a connecting member 20 that reinforces the periphery of the gap 16 is provided at this site. The connecting member 20 is located between the pillar constituent members 21 and 22 in the vehicle longitudinal direction. The connecting member 20 is a member extending in the vertical direction, and connects the inner panel 14 and the wheel house 15 to reinforce the surrounding structure. As shown in FIG. 4, the gap 16 is substantially partitioned into a front portion and a rear portion of the connecting member 20 in the vehicle front-rear direction.

  Reinforcing members 17 and 18 are disposed between the outer panel 11 and the inner panel 14. The reinforcing members 17 and 18 are arranged mainly for the purpose of suppressing deformation of the outer panel 11 inward in the vehicle width direction. As shown in FIG. 3, in this embodiment, two reinforcing members 17 and one reinforcing member 18 are arranged. One of the reinforcing members 17 is a front portion of the gap 16, the reinforcing member 18 is a rear portion of the gap 16, and the remaining one of the reinforcing members 17 is partially overlapped with the connecting member 20. Is arranged. According to this embodiment, since the reinforcing members 17 and 18 are provided so as to overlap the gap 16 when viewed from the vehicle width direction, the torsional rigidity around the gap 16 can be improved. Note that only the reinforcing member 17 or the reinforcing member 18 may be used, or other reinforcing members having different lengths and shapes may be used. Further, the number is not limited, and may be 1, 2 or 4 or more. When using a plurality of reinforcing members, the number of reinforcing members may be arbitrarily determined.

  Here, the reinforcing members 17 and 18 will be further described with reference to FIGS. 5 and 6. 5A is a perspective view of the reinforcing member 17, FIG. 5B is a perspective view of the reinforcing member 18, and FIG. 5C is a cross-sectional view taken along the line II-II in FIG. 5B.

  The reinforcing member 17 is formed of, for example, a metal plate-like member and has a shape that is long in the vertical direction when viewed from the vehicle width direction. The reinforcing member 17 has a fixing portion 171 fixed to the slide rail 12 at the lower portion. The reinforcing member 17 has an outer extending portion 172, an upper extending portion 174, and an inner extending portion 175 in order from the fixed portion 171 upward. Similarly, the reinforcing member 18 includes a fixing portion 181, an outer extending portion 182, and an upper extending portion 184, but does not have a configuration corresponding to the inner extending portion 175 in the reinforcing member 17.

In the present embodiment, the upwardly extending portion 174 has a vertical bead 176 that protrudes outward in the vehicle width direction and extends in the vertical direction, as shown in the cross-sectional view taken along the line II-II in FIG. According to this embodiment, the rigidity of the reinforcing member 17 itself can be increased. Therefore, the deformation of the outer panel 11 can be further suppressed. Note that the vertical bead 176 may protrude inward in the vehicle width direction. Further, the reinforcing member 17 may employ a configuration in which the vertical bead 176 is provided in at least a part of the upward extending portion 174 or a configuration in which the vertical bead 176 is not provided. The reinforcing member 18 can be provided with a vertical bead 186 with the same configuration.

  Next, the arrangement structure of the reinforcing members 17 and 18 will be described. 6 is a cross-sectional view taken along the line II of FIG. Hereinafter, the arrangement structure of the reinforcing member 17 will be described in detail by using the reinforcing member 17, but the configuration and operational effects of the reinforcing member 18 other than the inner extending portion 175 are the same as those of the reinforcing member 17.

  The fixing portion 171 of the reinforcing member 17 is fixed to the slide rail 12. Here, the slide rail 12 in the present embodiment includes a C-shaped cross-section including an upper wall 121, a lower wall 122, and a side wall 123, and the outer panel 11 is recessed inward in the vehicle width direction at a portion where the slide rail 12 is disposed. A recess 112 is provided. The fixing portion 171 is fixed to the side wall 123 that is the inner end in the vehicle width direction of the slide rail 12 with the recess 112 of the outer panel 11 interposed therebetween. By fixing the reinforcing member 17 to the slide rail 12 having high rigidity, the rigidity of the reinforcing member 17 and its periphery can be improved. The fixing method may be, for example, mechanical joining by bolt fastening or metallurgical joining by welding or the like.

  Here, the outer panel 11 is in contact with the fixing portion 171 at the concave portion 112, but the outer panel 11 extends outward in the vehicle width direction above the concave portion 112, so that the outer panel 11 and the reinforcing member 17 are separated above the fixing portion 171. is doing. The reinforcing member 17 has an outer extending portion 172 that extends outward in the vehicle width direction at a position above the fixed portion 171. Since the reinforcing member 17 extends outward in the vehicle width direction by the outer extending portion 172 at a position separated from the outer panel 11, a gap in the vehicle width direction between the outer panel 11 and the reinforcing member 17 is reduced. In the present embodiment, the outer extending portion 172 is inclined upward on the outer side in the vehicle width direction, but may be substantially horizontal in the vehicle width direction. The vertical distance between the fixed portion 171 and the outer extending portion 172 is not limited. For example, the outer extending portion 172 may be in contact with the upper surface of the recess 112 and extend outward in the vehicle width direction.

  Further, the reinforcing member 17 has an upward extending portion 174 extending upward from the end portion 173 of the outer extending portion 172 on the outer panel 11 side. The upper extending portion 174 is arranged at a position where the outer extending portion 172 has a small gap in the vehicle width direction with the outer panel 11. Therefore, when the outer panel 11 is bent, it becomes easy to hit the reinforcing member 17, and the bending can be prevented. That is, the deformation | transformation (what is called stickiness etc.) to the vehicle width direction inner side of the outer panel 11 can be suppressed. In the present embodiment, the outer panel 11 and the upward extending portion 174 are in contact with each other. According to the present embodiment, since the external force applied to the outer panel 11 acting inward in the vehicle width direction can be directly received by the reinforcing member 17, deformation of the outer panel 11 can be further suppressed. In addition, the outer panel 11 and the upward extending portion 174 may be configured to be at least partially in contact with each other, or may be configured to not be in contact with each other when no external force is applied (a configuration having a slight gap). Good.

  In the present embodiment, the upward extending portion 174 is disposed so as to overlap the bead 111 of the outer panel 11 when viewed from the vehicle width direction. According to this embodiment, the rigidity of the periphery of the bead 111 can be improved. Further, in the present embodiment, the upward extending portion 174 has a curved portion 177 that matches the shape of the bead 111 at a position overlapping the bead 111 of the outer panel 11. According to this embodiment, since the area which the outer panel 11 and the upward extension part 174 contact becomes large, a deformation | transformation of the outer panel 11 can be suppressed more. Note that a configuration without the curved portion 177 can be employed for the upward extending portion 174.

  Further, in the present embodiment, the reinforcing member 17 has an inner extending portion 175 extending from the upper extending portion 174 inward in the vehicle width direction. The inner extending portion 175 may be substantially horizontal in the vehicle width direction. According to the present embodiment, since the distance between the reinforcing member 17 and the inner panel 14 in the vehicle width direction is shortened, the inner panel 14 can be easily hit via the reinforcing member 17 when the outer panel 11 is bent. Therefore, the deformation of the outer panel 11 can be suppressed by transmitting the load to the inner panel 14.

  Further, in this embodiment, the reinforcing member 17 contacts the inner panel 14 at the upper end portion 178 extending from the inner end portion of the inner extending portion 175 in the vehicle width direction. According to the present embodiment, an external force acting on the outer panel 11 acting inward in the vehicle width direction can be directly received by the inner panel 14 via the reinforcing member 17, so that the deformation of the outer panel 11 can be further suppressed. Note that the length of the upper end 178 is not limited. Further, the reinforcing member 17 may be configured such that the upper end portion 178 abuts at least a part of the inner panel 14 or does not abut. Further, a configuration without the inner extending portion 175 and the upper end portion 178 such as the reinforcing member 18 can be employed.

  The reinforcing member 17 may be fixed to the inner panel 14 at an upper end 178 that contacts the inner panel 14. The fixing method may be, for example, mechanical joining by bolt fastening or metallurgical joining by welding or the like.
