Problems solved by technology

[0003] However, with such a bumper bracket mounting structure, it may be difficult to set a difference in strength against a collision load at a part where the plurality of grooves are formed due to restrictions such as the cross-sectional shape of the front side member or the like.
Also, in this case, when the vehicle encounters a frontal collision, it is difficult to squeeze and deform the plurality of grooves sequentially from the front side of the vehicle, so energy absorption efficiency may decrease.

Embodiment Construction

[0025] Hereinafter, an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

[0026] Arrows "up" (UP), "rear" (RR) and "outside" (OUT) in the figure represent the upper side in the vertical direction of the vehicle, the rear side in the longitudinal direction of the vehicle and the direction in the width direction of the vehicle, respectively. Outboard direction (that is, the right side as viewed from the front of the vehicle).

[0027] Such as figure 1 As shown, a vehicle body structure 10 according to an example embodiment of the present invention includes a bumper reinforcement 12 , a front side member 14 serving as a side member of the present invention, and a bumper bracket 16 .

[0028] The bumper reinforcement 12 is formed in a long shape with the vehicle width direction as the longitudinal direction, and is arranged on the front portion of the vehicle body (that is, the end portion of the vehicle body in the vehi...

Abstract

A vehicle body structure (10) includes a bumper reinforcement (12), a front side member (14), and a bumper stay (16). The front side member is formed with a closed section portion (34), and a protruding portion (42) that protrudes from this closed section portion toward a vehicle front side. The bumper stay, together with a protruding portion, forms an open section portion (74). Also, a notch (38) is formed on the vehicle width direction inside of the closed section portion, and a cutout (80) is formed on the vehicle width direction outside of the open section portion. Opposing wall portions (54) that are fixed to protruding opposing portions (44) and opposing wall portions (24) that connect the cutout and the notch are formed on the bumper stay. These opposing wall portions (54) are formed with extending edge portions (82) that extend from the cutout side toward the notch side.

Description

technical field [0001] The present invention relates to vehicle body structures. Background technique [0002] For example, Japanese Patent Application Publication No. 60-124552 (JP60-124552A) describes a bumper bracket mounting structure that includes a bumper bracket and a front side member, the bumper bracket can be mounted to the A front end portion of the front side member, and a plurality of beads in the front side member are formed at intervals in the vehicle longitudinal direction on corner portions of an upper wall and a vertical wall of the front end portion. [0003] However, with such a bumper bracket mounting structure, it may be difficult to provide a difference in strength against a collision load at the part where the plurality of grooves are formed due to restrictions such as the cross-sectional shape of the front side member or the like. Also, in this case, when the vehicle encounters a frontal collision, it is difficult to press and deform the plurality o...
