Embodiment Construction

[0059] Hereinafter, the most preferable embodiment of the present invention will be described with reference to the drawings. Moreover, the so-called "front (Fr)", "rear (Rr)", "left (L)" and "right (R)" are all directions seen by the driver.

[0060] 【Example】

[0061] The vehicle body front structure 10 in the embodiment will be described. The vehicle body front structure 10 is a substantially bilaterally symmetrical member. Hereinafter, the same symbols are assigned to the left and right components, the left components will be described in detail, and the detailed description of the right components will be omitted.

[0062] Such as figure 1 , figure 2 As shown, the vehicle body front structure 10 has: a left front side frame 11, which is arranged on the left side in the vehicle width direction; a left front pillar 12, which is erected on the outside of the left front side frame 11 in the vehicle width direction; The left front pillar 12 extends forward of the vehicle...

Abstract

The present invention provides a vehicle body front structure capable of suppressing the overall length of the vehicle body and stably absorbing impact energy. A vehicle body front structure (10), in which a subframe (25) is arranged under a left front side frame (11) and a right front side frame (11). The left front frame 11 has a first weak portion (35). The subframe (25) has a second weak portion (95) and an extension portion (94). The front edge portion (94a) of the extension portion (94) is located on the front surface (23b) of the left end portion of the bumper (23a) when the left end portion (23a) of the bumper and the left bumper bracket (22) collapse due to an impact load. same location.

Description

technical field [0001] The invention relates to a vehicle body front structure in which a front side frame extends along the front and rear direction of the vehicle body and a subframe is arranged under the front side frame. Background technique [0002] There is a vehicle body front structure in which the front part of the front side frame protrudes toward the front of the vehicle body, the protruding front part is formed as a weak part, and an auxiliary vehicle is provided under the weak part behind the vehicle body (that is, under the front side frame). shelf. [0003] According to this front structure of the vehicle body, when an impact load is applied from the front of the vehicle body due to a frontal collision, the fragile portion is compressively deformed by the applied impact load at the initial stage of the frontal collision. After compressive deformation of the vulnerable portion, the front side frame is bent and deformed by bending the subframe in the late stage...
