The invention relates to a vehicle rear side wall assembly, a vehicle rear side wall system and a vehicle. The D-column assembly is connected to the C-column roof side rail, a rear longitudinal beam is fixed to the end, away from the C-column roof side rail, of the D-column assembly, the rear longitudinal beam extends in the X direction of the vehicle, and a shock absorber fixing piece is installed on the rear longitudinal beam; one end of the reinforcing beam assembly is fixed to the side, close to the C-column upper edge beam, of the D-column assembly, the other end of the reinforcing beam assembly is fixed to the rear longitudinal beam, and the reinforcing beam assembly is connected to the shock absorber fixing piece and used for reinforcing the rigidity of a shock absorber mounting point in the shock absorber fixing piece. By arranging the stiffening beam assembly, the overall rigidity of the C-column-free vehicle is improved, the stiffening beam assembly is connected to the shock absorber fixing piece, the rigidity around a shock absorber installation point can be enhanced, the situation that the installation point is loosened or damaged due to the fact that the shock absorber bears too large force is avoided, and when the vehicle is collided, collision force borne by the upper edge beam of the C column can also be transmitted to the stiffening beam assembly, so that the vehicle is prevented from being damaged. And the overall safety is enhanced.

    本申请涉及一种车辆后侧围总成、车辆后侧围系统及车辆,其包括:C柱上边梁;D柱总成,D柱总成连接于C柱上边梁,D柱总成远离C柱上边梁的一端固定有后纵梁,后纵梁沿车辆的X向延伸,后纵梁安装有减震器固定件;加强梁总成,加强梁总成的一端固定于D柱总成靠近C柱上边梁的一侧,另一端固定于后纵梁,加强梁总成连接于减震器固定件,用于加强减震器固定件中减震器安装点的刚性。通过设置加强梁总成,增加无C柱车辆的整体刚性,加强梁总成连接于减震器固定件,还能增强减震器安装点周围的刚性,防止因减震器受力过大而导致的安装点松动或损坏,车辆受到撞击时,C柱上边梁处受到的撞击力也能传递至加强梁总成,增强整体安全性。
