The invention discloses a vehicle body rear portion and a vehicle, and the vehicle body rear portion comprises a rear anti-collision beam, a front anti-collision beam, a front anti-collision beam, a front anti-collision beam and a rear anti-collision beam, and the two ends of the rear anti-collision beam are connected with vehicle body rear longitudinal beams; the rear cross beam is formed by extruding profiles, the end part of the rear cross beam is relatively fixed with the rear longitudinal beam of the automobile body, the rear cross beam is positioned above the rear anti-collision beam and is separated from the rear anti-collision beam, and the rear anti-collision beam is positioned behind the rear cross beam along the front-back direction of the automobile body. According to the vehicle body rear part, the rear anti-collision beam and the rear cross beam are arranged to be connected with the vehicle body rear longitudinal beam, the structural strength of the vehicle body rear part can be improved, two force transmission paths can be formed after the vehicle body tail collides, the vehicle body tail collision performance is improved, the X-direction force transmission performance of the vehicle body is facilitated, and then a rear trunk and a hydrogen tank mounting point can be protected against deformation.
本发明公开了一种车身后部和车辆,所述车身后部,包括:后防撞梁,所述后防撞梁的两端与车身后纵梁相连;后横梁,所述后横梁为型材挤压成型,所述后横梁的端部与所述车身后纵梁相对固定,所述后横梁位于所述后防撞梁上方且与所述后防撞梁间隔开,沿车身前后方向,所述后防撞梁位于所述后横梁的后方。本发明的车身后部,通过设置后防撞梁和后横梁与车身后纵梁连接,可提升车身后部的结构强度,且在车身尾部碰撞后可形成两条传力路径,提升了车身尾碰性能,利于车身X向的传力性能,进而可保护后行李箱和氢罐安装点不变形。
