The invention belongs to the technical field of vehicle body platforms, and concretely relates to a vehicle body front structure. The vehicle body front structure comprises a front anti-collision beam, an energy absorption piece and a front longitudinal beam which are sequentially connected in the front-back direction of a vehicle body; buffer pieces are arranged between the front longitudinal beam and the energy absorption piece; an auxiliary frame is arranged below the front longitudinal beam; the auxiliary frame comprises an auxiliary frame body and a U-shaped support, the two ends of an opening of the U-shaped support are connected with the auxiliary frame body respectively, and the two ends, away from the opening, of the U-shaped support are connected with the buffer pieces respectively; and the U-shaped support is of a detachable structure. According to the vehicle body front structure, due to the fact that the U-shaped support and the vehicle frame body are of the detachable structure, for collision performance of different vehicle types, the U-shaped support can be selectively installed and connected to the buffer pieces through the U-shaped support, and the anti-collisionperformance of the front portion of the vehicle body is improved; or the U-shaped support is detached, so that the cost is reduced, different collision performance requirements of different vehicle types are met, and the universality is good.

    本发明属于车身平台技术领域,具体涉及一种车身的前部结构,车身的前部结构包括沿车身前后方向依次连接的前防撞梁、吸能件、前纵梁;所述前纵梁与所述吸能件之间设置有缓冲件;所述前纵梁下方设有副车架;所述副车架包括副车架本体和U型支架,所述U型支架开口处的两端分别与所述副车架本体连接,所述U型支架远离所述开口的两端分别与所述缓冲件连接;所述U型支架为可拆卸结构。在本发明的车身前部结构中,由于U型支架与车架本体之间为可拆卸结构,对于不同车型的碰撞性能,可选择的安装U型支架,通过U型支架连接至缓冲件,提高车身前部的防碰撞性能;或者拆卸掉U型支架,降低成本,满足不同车型的不同碰撞性能要求,通用性好。
