A rear longitudinal beam assembly comprises a rear longitudinal beam formed by a thermal forming process, the rear longitudinal beam comprises a longitudinal beam front section close to the tail of avehicle body, the longitudinal beam front section comprises a collision maintaining section and a collision collapsing section, an induction bending rib is arranged at one end, far away from the collision collapsing section, of the collision maintaining section, the collision collapsing section comprises a collapsing energy absorption section, a first cutting section and a second cutting section,the first cutting section and the second cutting section can be removed through cutting, the second cutting section is connected between the collapsing energy absorption section and the first cuttingsection, the end, away from the second cutting section, of the collapsing energy absorption section is connected with the collision maintaining section, and a first collapsing rib is arranged at the joint of the collapsing energy absorption section and the collision maintaining section. The rear longitudinal beam assembly can solve the problems that rear longitudinal beam molds of multiple vehicletypes on the same platform are not shared, and the cost is not optimized. The invention also relates to a vehicle.
一种后纵梁总成,包括由热成型工艺形成的后纵梁,后纵梁包括靠近车身尾部的纵梁前段,纵梁前段包括碰撞保持段和碰撞溃缩段,碰撞保持段远离碰撞溃缩段的一端设有诱导弯折筋,碰撞溃缩段包括溃缩吸能段以及可裁切去除的第一裁切段和第二裁切段,第二裁切段连接于溃缩吸能段与第一裁切段之间,溃缩吸能段远离第二裁切段的一端与碰撞保持段连接,溃缩吸能段与碰撞保持段的连接处设有第一溃缩筋。本发明的后纵梁总成能解决同平台多款车型后纵梁模具不共用,成本未优化的问题。本发明还涉及一种车辆。
