The invention relates to a vehicle front end structure with small offset collision. The vehicle front end structure comprises a front longitudinal beam, a front auxiliary frame, a front anti-collision beam and a Shotgun beam. The front auxiliary frame is positioned below the front longitudinal beam; the position, close to the front end, of the Shotgun beam is connected with an outer plate of a front longitudinal beam, the rear end of the Shotgun beam is connected with the upper end of an automobile A column, the front end of the Shotgun beam extends downwards and is connected with a front auxiliary frame, and a closed energy absorption cavity is defined by the front longitudinal beam, the Shotgun beam and the automobile A column. The front anti-collision beam is installed at the front end of the front longitudinal beam and is transversely arranged in the width direction of the vehicle body, according to the technical scheme, through the integrated collaborative design of the front anti-collision beam, the front longitudinal beam, the shotgun beam and the front auxiliary frame, the purposes of better energy absorption and more Y-direction sliding-out can be achieved when 25% of small offset collision happens to the vehicle, and the anti-collision effect is good. Therefore, the collision of the counterguard to the A column is reduced or avoided, the integrity of a passenger compartment can be ensured, and the 25% small offset collision performance of the vehicle is greatly improved.
本发明涉及一种小偏置碰撞的车辆前端结构,包括前纵梁、前副车架、前防撞梁和Shotgun梁;前副车架位于前纵梁的下方;Shotgun梁靠近前端的位置与前纵梁的外板连接,Shotgun梁的后端与汽车A柱的上端连接,Shotgun梁的前端向下延伸并与前副车架连接,前纵梁、Shotgun梁和汽车A柱围合形成封闭的吸能空腔;前防撞梁安装于前纵梁的前端,前防撞梁沿车身宽度方向横向布置,本技术方案通过对前防撞梁、前纵梁、shotgun梁、前副车架的一体式协同设计,可以在车辆发生25%小偏置碰撞时,实现更好的吸能和更多Y向滑出的目的,从而减少或者避免壁障对A柱的撞击,这样就可以保证乘员舱的完整性,大幅改善车辆的25%小偏置碰撞性能。
