The invention relates to the technical field of vehicle parts, and provides a vehicle body rear assembly and a vehicle, the vehicle body rear assembly comprises a rear side wall, the rear side wall comprises a C column, a reinforcing beam, a D column, a first longitudinal beam, a second longitudinal beam and a third longitudinal beam, and the C column, the reinforcing beam and the D column are sequentially arranged in the front-back direction of the vehicle; the first longitudinal beam, the second longitudinal beam and the third longitudinal beam are sequentially arranged in the vertical direction of the vehicle, the ends, in the front-back direction, of the first longitudinal beam, the second longitudinal beam and the third longitudinal beam are connected to the C column, and the other ends, in the front-back direction, of the first longitudinal beam, the second longitudinal beam and the third longitudinal beam are connected to the D column. The two ends, in the vertical direction, of the reinforcing beam are connected to the first longitudinal beam and the third longitudinal beam correspondingly. Therefore, the criss-cross structure shaped like the Chinese character'tian 'can be used for optimizing the force transmission path of the rear side wall and improving the bending resistance and the torsion resistance of the rear side wall, so that the torsional rigidity and the torsional mode of the vehicle body rear assembly are improved, and the riding comfort of passengers in the rear row is improved.

    本发明涉及车辆零部件技术领域,并提供了一种车身后部总成及车辆,车身后部总成包括后侧围,后侧围包括C柱、加强梁、D柱、第一纵梁、第二纵梁和第三纵梁,C柱、加强梁和D柱沿车辆的前后方向依次设置,第一纵梁、第二纵梁和第三纵梁沿车辆的上下方向依次设置,且第一纵梁、第二纵梁和第三纵梁沿前后方向的一端分别连接于C柱,第一纵梁、第二纵梁和第三纵梁沿前后方向的另一端分别连接于D柱,加强梁沿上下方向的两端分别连接于第一纵梁和第三纵梁。这样,可以利用纵横交错的田字形结构来优化后侧围的传力路径,提高后侧围的抗弯曲性能和抗扭性能,从而提升车身后部总成的扭转刚度和扭转模态,进而提升后排乘客的乘坐舒适性。
