The invention provides a vehicle body rear end force transmission structure and a vehicle. The vehicle body rear end force transmission structure comprises a rear floor front longitudinal beam, a rear side wall D column structure, a channel connecting plate, a first force transmission channel and a second force transmission channel, the rear floor front longitudinal beam, the rear side wall D column structure, the channel connecting plate, the first force transmission channel and the second force transmission channel jointly form a vehicle body rear end force transmission structure, so that the upper portion of the vehicle body rear end force transmission structure is in lap joint with the top cover safely and firmly, the first force transmission channel and the second force transmission channel are both arranged to be vertically through, and the upper portions of the first force transmission channel and the second force transmission channel are in lap joint with the top cover; the connection of upper and lower paths is improved, the jacking performance is improved, the paths are reasonably arranged, the matching of the vehicle body rear end force transfer structure and each hard point of the chassis is improved, and the problems that the upper part of the existing vehicle body rear end force transfer structure and the top cover are relatively weak in lap joint, so that jacking stress energy absorption is influenced, and the whole vehicle resonates and the riding comfort is poor due to discontinuous force transfer paths can be solved.
本发明提供了一种车身后端传力结构及汽车,该车身后端传力结构包括包括后地板前纵梁、后侧围D柱结构、通道连接板、上下贯通的第一传力通道和第二传力通道。本发明中,后地板前纵梁、后侧围D柱结构、通道连接板、上下贯通的第一传力通道和第二传力通道共同组成车身后端传力结构,使车身后端传力结构上部与顶盖搭接安全牢靠,第一传力通道和第二传力通道均设为上下贯通,且上部与顶盖搭接,提升上下路径的连接并提升顶压性能,路径合理布局,提升车身后端传力结构与底盘各个硬点的匹配,可以解决现有车身后端传力结构上部与顶盖搭接比较薄弱影响顶压受力吸能,传力路径不连贯导致整车共振,乘坐舒适性差的问题。
