The invention provides a vehicle body structure and a vehicle provided with the same. The vehicle body structure comprises a rear floor longitudinal beam and a reinforcing sealing plate arranged in the rear floor longitudinal beam. The reinforcing sealing plate extends in the front-back direction of the whole vehicle, and the interior of the rear floor longitudinal beam is divided into an upper cavity and a lower cavity which are located above and below the reinforcing sealing plate respectively. The rear end of the reinforcing sealing plate corresponds to a rear auxiliary frame front mounting portion in the rear floor longitudinal beam, and the front end of the reinforcing sealing plate extends out of the front end of the rear floor longitudinal beam. According to the vehicle body structure, the formed double-cavity structure can be used for increasing the structural strength of the rear floor longitudinal beam, the collision force transmission capacity of the rear floor longitudinal beam is improved, meanwhile, the dynamic stiffness of a rear auxiliary frame installation point can be improved, and the torsion performance of the rear portion of the vehicle body can be improved.
本发明提供了一种车身结构及设有其的车辆,本发明的车身结构包括后地板纵梁,以及设于所述后地板纵梁内的加强封板;所述加强封板沿整车前后方向延伸,并在所述后地板纵梁内分隔出分别位于所述加强封板上下方的上部腔体与下部腔体;所述加强封板的后端与所述后地板纵梁内的后副车架前安装部对应设置,所述加强封板的前端由所述后地板纵梁的前端伸出。本发明的车身结构,能够利用形成的双腔体结构增加后地板纵梁的结构强度,提升后地板纵梁的碰撞力传递能力,同时也能够提高后副车架安装点的动刚度,能够提高车身后部的扭转性能。
