The invention provides a vehicle body anti-collision device and a vehicle, the vehicle body anti-collision device comprises a first force transmission assembly, the first force transmission assembly at least comprises a first transverse force transmission structure, longitudinal force transmission structures are arranged on the two sides of the first transverse force transmission structure in the width direction of a vehicle body, and the longitudinal force transmission structures on the two sides extend in the length direction of the vehicle body; a first space is defined by the first transverse force transmission structure and the longitudinal force transmission structures on the two sides. The second force transmission assembly is arranged in the first space and at least comprises an arch-shaped force transmission structure, an opening of the arch-shaped force transmission structure faces the side away from the first transverse force transmission structure, and the two ends of the arch-shaped force transmission structure are installed on the longitudinal force transmission structures on the corresponding sides correspondingly. According to the scheme, the second force transmission assembly is additionally arranged on the basis of the first force transmission assembly, a single force transmission path is expanded into multiple force transmission paths, the situation of structural failure easily caused by the single path is avoided, better energy absorption efficiency is achieved, meanwhile, the amount of intrusion into a cab caused by collision is reduced, and then the safety performance of the vehicle is improved.
本申请提供一种车身防撞装置及车辆,该车身防撞装置包括:第一传力组件,第一传力组件至少包括第一横传力结构,第一横传力结构沿车身宽度方向的两侧均设有纵传力结构,两侧的纵传力结构沿车身长度方向延伸;第一横传力结构与两侧的纵传力结构围成第一空间;第二传力组件设于第一空间内,第二传力组件至少包括拱形传力结构,拱形传力结构的开口朝向远离第一横传力结构侧,拱形传力结构的两端分别安装于对应侧的纵传力结构上。该方案在第一传力组件的基础上增设了第二传力组件,将单一传力路径拓展为多种传力路径,规避了单一路径容易产生的结构失效情况,具有更好的吸能效能,同时也减少撞击进入驾驶舱的侵入量,进而提升车辆安全性能。
