The invention relates to a rear wall assembly and a vehicle. A rear wall inner plate is provided with a first connecting area, a second connecting area, a third connecting area and a fourth connecting area from top to bottom. The first fixing plate assembly is connected with the rear wall inner plate to form a first stress cavity located between the first connecting area and the second connecting area and a second stress cavity located between the second connecting area and the third connecting area; the fourth connecting area is an annular area, and under the cooperation of the third connecting area and the fourth connecting area, the first fixing plate assembly and the rear wall inner plate are enclosed to form a third stress cavity; the upper side and the lower side of the rear wall outer plate are connected with the other side face, in the thickness direction, of the first fixing plate assembly respectively, the connecting areas of the upper side and the lower side of the rear wall outer plate correspond to the first connecting area and the third connecting area respectively, and a fourth stress cavity is formed between the first fixing plate assembly and the connecting areas of the upper side and the lower side of the rear wall outer plate. And the mechanical property of the rear wall assembly and the dynamic stiffness of a mounting point are improved.
本申请涉及一种后围总成及车辆,后围里板从上至下设有第一连接区域、第二连接区域、第三连接区域和第四连接区域;第一固定板总成与后围里板连接,以形成位于第一连接区域和第二连接区域之间的第一受力腔体,位于第二连接区域和第三连接区域之间的第二受力腔体;第四连接区域为环状区域,在第三连接区域与第四连接区域的配合下,第一固定板总成同后围里板围合形成第三受力腔体;后围外板上下两侧分别与第一固定板总成在厚度方向上的另一侧面连接,后围外板上下两侧的连接区域分别与第一连接区域和第三连接区域对应,以和第一固定板总成之间形成第四受力腔体,以上结构优化了后围总成的受力路径,改善了后围总成的力学性能和安装点的动刚度。
