Front body reinforcement structure

Abstract

A front vehicle body reinforcing structure may include front side members which are disposed at both left and right sides of the vehicle, each of which includes a front tip portion that is positioned at a front side of the vehicle, and each of which has a first closed cross section and front fender apron members which are disposed at both left and right sides of the vehicle, each of which includes a front tip portion that is positioned at the front side in the length direction of the vehicle and coupled to the front tip portion of the front side member, and each of which has a second closed cross section, thereby improving performance for coping with a frontal collision of the vehicle.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2013-0157655 filed on December 17, 2013, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a front door reinforcement structure which improves the performance of dealing with a frontal collision accident of a vehicle by forming a front tip portion of a front fender member configured in a lengthwise direction of a vehicle. The front body of the vehicle is such that the front tip portion of the front fender member extends to the front tip portion of the front side member in the length direction of the vehicle and is integrally coupled to the front tip portion of the front side member. Background technique [0004] Generally, the front body of a vehicle is a structure that is disposed on the front side in the length direction of the vehicle and forms...

Problems solved by technology

[0008] In the case where a vehicle provided with a front body having the above structure undergoes a frontal collision while the vehicle is running and overlaps with a collision object (such as an obstacle or other vehicle) in a small area, that is, when the collision object is in the width direction of the vehicle with the collision object In the event of a collision with a vehicle in a state deviated to one side, such as figure 1 As shown in , the width W of the front tip portion of the front side member 110 becomes smaller so that the overlapping width W between the collision object 100 and the front side member 110 becomes smaller, so there is a problem that the front side member 110 cannot Properly deformed backwards, but bent upwards in the height direction of the vehicle or left and right in the width direction of the vehicle, cannot safely protect the occupants because the front side members cannot effectively handle the small overlapping area in front of the vehicle, and cause excessive collision damage to the vehicle
