Abstract

PROBLEM TO BE SOLVED: To enhance a support strength of the vertical direction of a bumper reinforcement, increase the energy absorption quantity and prevent a side member from being rusted. SOLUTION: A fitting part 18 of a front side member 14 has a closed section structure whose vertical direction of a vehicle is narrowed and is continued to the closed face of a main body part 16. The both side walls of the fitting part 18 are enlarged by drawing a continuous curve from the both side wall parts 16B, etc., of the main body part, 16 toward the front part, of the vehicle. The sectional shape of the bumper reinforcement 12 viewed from the car width direction is a so-called B-section type forming a recess part 28 in the vehicle rear side between a top closed section part 24 and a bottom closed section part 26, and the fitting part 18 of the front side member 14 is inserted into the recess part 28 so as to be fixed by a bolt 38 and a nut 40.

Further, at the time of a high-speed collision, the bumper reinforcement and the side member attachment portion are deformed before the body portion of the side member is deformed, so that the deformation load is higher and the amount of energy absorption is larger than the deformation of only the bumper reinforcement. . Also, the mounting part (tip) of the side member has a closed cross-sectional structure, and since the cut surface of the material is only on the front of the mounting part, the place where rust is generated is small,
Rust on side members can be prevented.

Further, at the time of a high-speed collision, the bumper reinforcement and the side member attachment portion are deformed before the body portion of the side member is deformed, so that the deformation load is higher and the amount of energy absorption is larger than the deformation of only the bumper reinforcement. . Further, the mounting portion (tip portion) of the side member has a closed cross-sectional structure, and since the cut surface of the material is located only on the front surface of the mounting portion, the location where rust is generated is small. In addition, since the mounting portion of the side member is inserted into the concave portion of the bumper reinforcement and the cut surface is not exposed, rainwater or the like rarely contacts the cut surface, and rainwater or the like enters the side member. Since it is difficult, rust on the side members can be further prevented.

In the bumper reinforcement mounting structure according to claim 2 or 3, the mounting portion is formed by enlarging the side wall portions in the vehicle width direction by drawing a continuous curve from both side wall portions in the vehicle width direction of the side member body. The fixing point with the bumper reinforcement is located outside the side member body in the vehicle width direction.

When an impact is applied to the direction end, that is, the deflection of the bumper reinforcement at the time of an offset collision can be reduced. Further, since the mounting portion is enlarged by a continuous curve from the side member main body, the input to the fixed point is transmitted in the axial direction of the side member main body, and the side member main body is securely buckled.

スメントが変形せずに、移動するのを防止できる。Therefore, when an impact is applied to the bumper reinforcement from the front-rear direction of the vehicle, the upper wall or the lower wall of the bumper reinforcement is supported by the upper wall and the lower wall of the side member, and the impact force is applied to the upper and lower sides of the vehicle. Since it does not escape in the direction, the upper and lower sides of the bumper reinforcement are in-plane compressed and sufficiently deformed. For this reason, it is possible to prevent the bumper reinforcement from moving without being deformed.
