The invention discloses a vehicle body structure for improving small offset collision performance, a design method and a vehicle, the vehicle body structure comprises a front anti-collision beam assembly, a front upper edge beam, a front longitudinal beam, a front auxiliary frame and a column A. The front anti-collision beam comprises a head-on beam and side oblique beams, the head-on beam is connected with the side oblique beams, the side oblique beams are arranged on the two sides of the head-on beam, and the front auxiliary frame is connected with the front anti-collision beam assembly. The front anti-collision beam energy absorption box is inclined by a preset angle towards the direction close to the vehicle body and is connected with the side oblique beam; the front anti-collision beam energy absorption box is connected with the front upper edge beam and the front longitudinal beam, and the front upper edge beam close to one side of the front anti-collision beam energy absorption box is connected with the front longitudinal beam. The middle of the A column is connected with the front roof side rail; one end, connected with the front longitudinal beam, of the front roof side rail extends downwards and is connected with the front auxiliary frame; the anti-collision device has a good anti-collision function and an obvious weight reduction effect; when the vehicle is subjected to small-offset collision, the purpose of better energy absorption can be achieved, so that the collision of the counterguard to the A column is reduced, the integrity of a passenger compartment is guaranteed, and the small-offset collision performance of the vehicle is improved.

    本发明公开了一种提升小偏置碰撞性能的车体结构、设计方法及车辆,其中,车体结构包括前防撞梁总成、前上边梁、前纵梁、前副车架和A柱,前防撞梁包括迎面梁和侧斜梁,迎面梁和侧斜梁连接,侧斜梁设置于迎面梁两侧,且向着靠近车体方向偏斜预设角度,前防撞梁吸能盒与侧斜梁连接;前防撞梁吸能盒分别与前上边梁和前纵梁连接,且靠近前防撞梁吸能盒一侧的前上边梁和前纵梁连接;A柱的中部与前上边梁连接;前上边梁与前纵梁连接的一端向下延伸,并与前副车架连接;本发明具有较好的防撞功能和明显的降重效果;可以在车辆发生小偏置碰撞时,实现更好的吸能目的,从而减少壁障对A柱的撞击,保证乘员舱的完整度,改善车辆的小偏置碰撞性能。
