The invention relates to an automobile front end collision force transmission structure which comprises a front end frame, a cooling system radiator, a main longitudinal beam, a front tire tread, a main energy absorption box fixing support, an auxiliary energy absorption box, an auxiliary anti-collision cross beam, a main energy absorption box, a main anti-collision cross beam, a cross beam connecting plate, an auxiliary frame connecting support and a main longitudinal beam front end fixing support. The main energy absorption box, the main anti-collision cross beam, the auxiliary energy absorption box, the auxiliary anti-collision cross beam and the cross beam connecting plate can be connected to form a full-coverage first-stage collision energy absorption protection cage type structure; the front end frame, the cooling system radiator, the main longitudinal beam, the front tire tread, the main energy absorption box fixing support, the auxiliary frame connecting support and the main longitudinal beam front end fixing support can be connected to form a full-coverage secondary collision energy absorption protection cage type structure. According to the structure, the upper, middle and lower multi-path force transfer design realizes effective coverage of the MPDB working condition evaluation area force transfer structure and reasonable distribution of counterguard collision contact loads, thereby reducing MPDB working condition counterguard compatibility penalty scores and greatly improving the automobile collision compatibility protection capability.

    本发明涉及一种汽车前端碰撞传力结构,包括前端框架、冷却系统散热器、主纵梁、前轮胎胎面、主吸能盒固定支座、副吸能盒、副防撞横梁、主吸能盒、主防撞横梁、横梁连接板、副车架连接支架和主纵梁前端固定支座;主吸能盒、主防撞横梁、副吸能盒、副防撞横梁与横梁连接板可连成全覆盖一级碰撞吸能防护笼式结构;前端框架、冷却系统散热器、主纵梁、前轮胎胎面、主吸能盒固定支座、副车架连接支架与主纵梁前端固定支座可连成全覆盖二级碰撞吸能防护笼式结构。本发明上中下多路径传力设计,实现MPDB工况评价区域传力结构有效覆盖,壁障碰撞接触载荷合理分布,从而降低MPDB工况壁障兼容性罚分,大幅提升汽车碰撞兼容性防护能力。
