Problems solved by technology

However, in either technique, if the colliding body collides with the vehicle at the time of a small overlap collision, if the position of the collision body deviates in the vehicle width direction, each part of the vehicle front such as the bumper reinforcement or one front side member may be damaged. The load sharing, abutment position, deformation moment, etc. will change, so the stability must not be reduced accordingly.

Abstract

A vehicle front structure having a bumper reinforcement arranged in the vehicle width direction at the front part of a pair of front side members is provided. A pair of extensions is provided to the bumper reinforcement at positions outside of the front side members in the vehicle width direction. Each extension is provided with a front protrusion protruding ahead of the bumper reinforcement at positions outside of the front side member on the front side, and a rear protrusion protruding backward on the rear side. At the time of a small overlap frontal crash, loads imposed on the extension are transmitted to and absorbed by the front side member by the rear protrusion via the front protrusion.

Description

technical field [0001] The present invention relates to a vehicle front portion structure having an extended portion at a vehicle width direction outer side of a bumper reinforcement extending in a vehicle width direction supported by a pair of front side members extending in a vehicle front and rear direction, in particular It relates to a front structure of a vehicle that transmits a load during a micro-overlap collision to a front side member via the extension portion. Background technique [0002] In the conventional vehicle front structure, in general, on the bumper reinforcement extended in the vehicle width direction supported by a pair of front side members extending in the vehicle front-rear direction, on the outer side in the vehicle width direction A pair of extensions are arranged at the position. The pair of extension portions are provided to extend further to the left and right outer sides from the portion where the left and right front side members contact th...
