Side body structure of vehicle

Abstract

The present invention provides a side body structure of a vehicle. The present invention aims to effectively reduce rearward movement of a hinge pillar and a dashboard, and further reduce a deformation of a cabin, by stably distributing an impact load applied to the hinge pillar from a vehicle front to rear side. A vehicle side body structure is provided, an inner hinge pillar member (22) is formed with a bend-facilitating portion (90) extending continuously or intermittently in the vertical direction Z of the vehicle and for facilitating a bending deformation of the inner hinge pillar member by protruding outwardly in the width directions X of the vehicle due to a concentration of a stress caused by an impact load applied to a hinge pillar (20) from the front side of the vehicle, and the bend-facilitating portion (90) is adjacently disposed on the front side of a front end part of the closed section space component (60) (70) (80) forming a closed section space (S1) (S2) (S3) extending continuously in the longitudinal directions Y of the vehicle along an outer surface of the inner hinge pillar member (22) in width directions X of the vehicle.

Description

technical field [0001] The present invention relates to a side body structure of a connecting portion of a hinge pillar and a side sill of a vehicle and its peripheral portion, and belongs to the technical field of vehicle body structures. Background technique [0002] Generally speaking, when a vehicle collides with the front, a pair of left and right front side frames (front side frames) provided at the front of the vehicle body so as to extend in the front-rear direction of the vehicle body collapse to absorb the impact load, and pass through the front side frame. The side beams distribute impact loads to various parts of the vehicle body, thereby suppressing deformation of the cabin. [0003] On the other hand, in the width direction of the vehicle body, in the event of a so-called small-area overlap collision in which an area of ​​the vehicle on the outer side of the front side member overlaps with the collision object, the front wheels arranged in this overlapping area...

AI Technical Summary

Problems solved by technology

[0008] In a vehicle having such a side body structure, when the above-mentioned small-area overlapping collision occurs, the outer side member member, which receives an impact load from the front side of the vehicle body, tends to buckle at the front end portion that does not form a closed cross section. The problem that the load distribution to the rear side of the vehicle body through the side members cannot be effectively realized
