The vehicle body rear structure comprises a door ring reinforcing plate, the door ring reinforcing plate comprises a top beam, a C column, a wheel cover beam and a bottom beam, the top beam extends in the front-back direction of the vehicle, the C column extends in the up-down direction of the vehicle, the upper end of the C column is connected with the rear end of the top beam, and the bottom beam extends in the front-back direction of the vehicle. In the direction from front to back, the wheel cover beam inclines upwards, the upper end of the wheel cover beam is connected with the lower end of the column C, the lower end of the wheel cover beam is connected with the rear end of the bottom beam, the column D is located behind the column C and connected with the column C, and the front surface of the column D is attached to and connected with the rear surface of the column C on the same side. According to the vehicle body rear structure and the door ring reinforcing plate, a coherent force transmission path is formed, the force transmission path is optimized, therefore, impact force borne by the vehicle body rear structure can be effectively absorbed and dispersed, and through the multi-channel force transmission path, the problem that due to the fact that impact loads are excessively concentrated, local structure damage or connection failure is caused is effectively solved.

    本发明公开了一种车身后部结构、车身总成及车辆,所述车身后部结构包括门环加强板,门环加强板包括顶梁、C柱、轮罩梁和底梁,顶梁沿车辆的前后方向延伸,C柱沿车辆的上下方向延伸且上端与顶梁的后端连接,底梁沿车辆的前后方向延伸,在由前至后的方向上,轮罩梁向上倾斜,轮罩梁的上端与C柱的下端连接,轮罩梁的下端与底梁的后端连接,D柱位于C柱后方且与C柱连接,D柱部分的前表面与同侧C柱的后表面贴合且连接。根据本发明的车身后部结构,门环加强板形成连贯的传力路径,优化传力路径,从而能够有效吸收和分散车身后部结构受到的冲击力,且实现通过多通道传力路径,有效避免解决冲击载荷过于集中造成局部结构损坏或连接失效的问题。
