A vehicle front end vehicle body collision safety structure comprises a guide structure, an energy absorption structure, an A column and a supporting structure. One end of the guide structure is fixedly connected to the column A, the other end of the guide structure is fixedly connected with one end of the supporting structure, and the other end of the supporting structure is fixedly connected to the column A through the energy absorption structure; the two guiding structures are symmetrically arranged at the front end of the vehicle, and the ends, connected with the supporting structures, of the guiding structures bend towards the inner side of the vehicle. By means of the guide device, the stretch bending direction is the Y direction of the vehicle body and is bent towards the interior of the vehicle, an outwards-arched closed-section aluminum profile structure is formed in a wheel casing area, the outwards-arched shape of the novel aluminum profile wheel casing reinforcing beam makes contact with a barrier in the small offset collision process, the Y-direction guide effect is achieved, Y-direction thrust is generated on the whole vehicle, and the whole vehicle is prevented from being damaged. The whole vehicle is pushed away from the vehicle body in the collision process, and the problem that the vehicle body is in rigid contact with the counterguard in the small-offset collision process, and large deformation is generated is solved.

    一种车辆前端车身碰撞安全结构,包括导向结构、吸能结构、A柱和支撑结构;导向结构的一端固定连接在A柱上,导向结构的另一端与支撑结构的一端固定连接,支撑结构的另一端通过吸能结构固定连接到A柱上;两个导向结构对称设置在车辆前端,且导向结构连接支撑结构的一端朝向车辆内侧弯曲。本发明通过导向装置,拉弯方向为车身Y向向车内弯曲,在轮罩区域形成一个外拱的封闭截面铝型材结构,在小偏置碰撞过程中通过这种新型的铝型材轮罩加强梁的外拱形状与壁障接触,起到Y向导向的作用,对整车产生一个Y向推力,将整车在碰撞过程中推开车身,避免车身在小偏置碰撞过程中与壁障刚性接触,产生大的变形的问题。
