The invention discloses a rear anti-collision beam assembly structure and a vehicle. The rear anti-collision beam assembly structure comprises a rear anti-collision beam body (1) and energy absorption boxes (2) arranged at the two ends of the rear anti-collision beam body (1). The energy absorption box (2) comprises a box body (21) and a mounting plate (22), the box body (21) is of a semi-closed structure formed by bending a plate and comprises a first opening and a second opening which are communicated, the first opening is fixedly connected with the rear anti-collision beam body (1), the mounting plate (22) is arranged on the second opening, and the mounting plate (22) turns over towards the outside of the box body (21). Based on the rear anti-collision beam assembly structure, the energy absorption box (2) is formed by bending the plate, cut excess materials are reduced, the utilization efficiency of the plate is improved, the mounting plate (22) of the energy absorption box (2) is arranged outside the energy absorption box (2), the stress area of a mounting point is increased during collision, the stability of collision is improved, the number of parts is reduced through bending forming of the whole plate, and the cost is reduced. Meanwhile, the welding procedure of the energy absorption box (2) is omitted, the weight of the rear anti-collision beam assembly can be greatly reduced, and cost is reduced.

    本申请公开了一种后防撞梁总成结构及车辆,所述后防撞梁总成结构包括后防撞梁主体(1)和设置在所述后防撞梁主体(1)两端的吸能盒(2);所述吸能盒(2)包括盒体(21)和安装板(22),所述盒体(21)为板材折弯形成的半封闭结构,包括连通的第一开口和第二开口,所述第一开口与所述后防撞梁主体(1)固定连接,所述第二开口上设有所述安装板(22),所述安装板(22)向所述盒体(21)的外部翻转。基于上述后防撞梁总成结构,通过板材折弯形成吸能盒(2)结构,减少了切除余料,提高板材的利用效率,吸能盒(2)的安装板(22)设置在吸能盒(2)的外部,在碰撞时安装点受力面积增大,提升了碰撞的稳定性,通过整块板材的折弯成型,减少了零件个数,同时节省了吸能盒(2)的焊接工序,可以极大的减轻后防撞梁总成的重量,降低成本。
