The invention provides a vehicle body structure and a vehicle with the vehicle body structure, and the vehicle body structure comprises an outer vehicle body structure which is provided with a first cavity; an inner vehicle body structure which is provided with a second cavity, where in the inner vehicle body structure is arranged in the first cavity, and the outer side wall of the inner vehicle body structure is separated from the inner side wall of the first cavity; an overhead suspension which connects the top of the inner vehicle body structure and the top of the outer vehicle body structure. When the vehicle encounters mine explosion, the overhead suspension can prolong the transmission path of an explosion load to attenuate the explosion load, and after the mine explosion, the explosion load reaches the bottom plate of the outer vehicle body structure through the protection assembly at the bottom and then reaches the overhead suspension through the side wall and the top of the outer vehicle body structure, the explosion load reaches the top, the side wall and the bottom plate of the inner vehicle body structure through the overhead suspension and is transmitted to the feet of passengers, the explosion load transmission path is lengthened, the intensity of the explosion load is greatly attenuated, and safety protection of the passengers in the vehicle is achieved.
本发明提供一种车身结构和具有其的车辆,车身结构包括:外车身结构,外车身结构具有第一腔室;内车身结构具有第二腔室,内车身结构设置于第一腔室中,内车身结构的外侧壁与第一腔室的内侧壁之间间隔开;顶置悬置连接内车身结构的顶部与外车身结构的顶部。当车辆遭遇地雷爆炸时,顶置悬置可以延长爆炸载荷的传递路径,起到对爆炸载荷的衰减,地雷爆炸后,爆炸载荷后经过底部的防护组件到达外车身结构的底板,然后经过外车身结构的侧围和顶部到达顶置悬置,经过顶置悬置达到内车身结构的顶部、侧围和底板传递至乘员脚部,爆炸载荷传递路径的加长,极大的衰减了爆炸载荷的强度,实现了对车内乘员的安全保护。
