The invention discloses a collision energy management vehicle body structure which comprises a chassis and an upper vehicle body; the chassis comprises two chassis longitudinal beams, three chassis cross beams, a front anti-collision beam and two threshold longitudinal beams; the upper vehicle body comprises two top cover longitudinal beams, four top cover cross beams, a front blocking beam, a vehicle head part and a vehicle tail part; the two top cover longitudinal beams are arranged side by side, and the front blocking beam and the four top cover cross beams are connected between the top cover longitudinal beams on the two sides and are sequentially spaced in the direction from the front ends of the top cover longitudinal beams to the tail ends of the top cover longitudinal beams; the front ends of the top cover longitudinal beams are connected with a vehicle head part, and the tail ends of the top cover longitudinal beams are connected with a vehicle tail part; and the chassis is fixedly connected with the upper vehicle body, and a middle column is connected between each threshold longitudinal beam and the corresponding top cover longitudinal beam. The collision energy management vehicle body structure is simple in structure and convenient to use, and the rigidity and collision safety performance of the whole vehicle are improved by adopting multi-element materials and a multi-ring structure path; while the strength of the vehicle body is ensured, the weight of the vehicle body is not increased, and a lightweight vehicle body framework is realized.

    本发明公开了一种碰撞能量管理车身结构,包括:底盘,包括两个底盘纵梁、三个底盘横梁、前防撞梁和两个门槛纵梁;上车体,包括两个顶盖纵梁、四个顶盖横梁、前挡梁、车头部和车尾部;所述两个顶盖纵梁并排设置,所述前挡梁和四个顶盖横梁均连接于两侧的所述顶盖纵梁之间,且沿所述顶盖纵梁前端至尾端的方向依次间隔开;所述顶盖纵梁前端连接有车头部,且其尾端连接有车尾部;其中,所述底盘与上车体固定连接,每个所述门槛纵梁和顶盖纵梁之间均连接有中柱。本发明的碰撞能量管理车身结构结构简单,使用方便,采用多元材料和多环结构路径提高整车刚度和碰撞安全性能;在保证车身强度的同时,不增加车身重量,实现轻量化车身架构。
