Vehicle body front part structure

Abstract

To provide a vehicle body front part structure which supports an impact load input from an upper member to a front pillar by using a simple structure without using a reinforcement member in a pillar inner. In a vehicle body front part structure 10, a rear end part 17b of a right upper member 17 is connected to a front part 16b of a right front pillar 16. The right front pillar 16 includes: a pillar outer 36 provided at an outer side in a vehicle width direction; and a pillar inner 37 provided at an inner side of the pillar outer 36 in the vehicle width direction. Multiple beads 64 are formed at the pillar inner 37. The beads 64 extend in a vehicle body fore and aft direction to secure rigidity of the pillar inner 37.

Description

Technical field [0001] The present invention relates to a vehicle body front structure, which has left and right front pillars on the outside in the vehicle width direction, and upper members extend from the front of each front pillar toward the front of the vehicle body. Background technique [0002] In the front structure of the vehicle body, there is known a structure in which a lower front wall is provided behind the vehicle body of the shock absorber housing, and a chamfered portion is formed at the corner between the lower front wall and the column inner member of the front pillar. A plurality of ribs are formed near the upper end of the chamfered portion (for example, refer to Patent Document 1). [0003] By forming a plurality of ribs in the vicinity of the upper end of the chamfered portion, it is possible to increase the rigidity of the corner without separately providing a reinforcing member. In addition, a shock absorber housing is provided in front of the vehicle body...

AI Technical Summary

Problems solved by technology

Accordingly, when a relatively large impact load is input to the upper member inner of the upper member or the pillar inner of the front pillar, the pillar inner may be deformed,

[0006] Therefore, a relatively large impact load transmitted to the pillar inner is transmitted from the front pillar to the roof, and it is difficult for the front structure of the vehicle body to receive the impact load. From this point of view, there is room for improvement.
