The automobile rear longitudinal beam assembly comprises a first longitudinal beam and a second longitudinal beam which are arranged in the length direction of an automobile body, the first longitudinal beam is provided with a first groove body, a plurality of separation ribs arranged at intervals and a plurality of strengthening structures, the separation ribs are arranged in the first groove body, and the strengthening structures are arranged in the first groove body. The reinforcing structures are arranged in the first groove to divide the first groove into a plurality of energy absorption cavities distributed in the height direction of the vehicle body, each reinforcing structure is arranged in the corresponding energy absorption cavity, the second longitudinal beams are connected with the energy absorption cavities facing the top of the vehicle body, and the second longitudinal beams face the tail of the vehicle body. According to the automobile rear longitudinal beam assembly provided by the embodiment of the invention, the strength can be improved through multi-section energy absorption, the probability of automobile deformation caused by overall deformation of the rear longitudinal beam assembly can be reduced, and the overall strength of an automobile and the riding safety of a user are improved.
本申请提供一种汽车后纵梁总成及车辆,后纵梁总成包括在车体的长度方向上排布的第一纵梁和第二纵梁,第一纵梁具有第一槽体、多个间隔设置的隔筋以及多个强化结构,多个隔筋设置于第一槽体内,以将第一槽体分隔为多个沿车体高度方向排布的吸能腔,每一个强化结构设置于一个吸能腔内,第二纵梁与朝向车体顶部的吸能腔相连,且第二纵梁朝向车体的尾部。本申请实施例提供的汽车后纵梁总成能够通过多段吸能提高强度,并能够降低后纵梁总成发生整体变形而引起车辆变形的几率,提高了汽车的整体强度以及用户的乘车安全。
