The invention provides a vehicle body reinforcing structure and a vehicle with the vehicle body reinforcing structure The vehicle body reinforcing structure comprises a rear floor framework in a rear floor assembly, front floor upper longitudinal beams arranged on the left side and the right side respectively and a front wall lower cross beam and further comprises a rear floor lower cross beam connected to the bottom of the rear floor framework and threshold beams arranged on the left side and the right side respectively. The torsion boxes are connected to the rear ends of the front cabin longitudinal beams on the left side and the right side respectively; the rear floor framework, the front wall lower cross beam, the front floor upper longitudinal beam on the two sides and the front wall longitudinal beam on the two sides are connected to form a first annular reinforcing structure, and the rear floor lower cross beam, the cabin rear section cross beam, the doorsill beams on the two sides and the torsion box are connected to form a second annular reinforcing structure. According to the vehicle body reinforcing structure, the structural strength and torsional rigidity of the vehicle body can be improved, the collision force transmission effect during collision can be improved, and the safety of the whole vehicle can be improved.

    本发明提供了一种车身加强结构和设有其的车辆,本发明的车身加强结构包括后地板总成中的后地板骨架,分设在左右两侧的前地板上纵梁,以及前围下横梁,还包括连接在后地板骨架底部的后地板下部横梁,分设在左右两侧的门槛梁,以及分别连接在左右两侧前机舱纵梁后端的扭力盒;后地板骨架、前围下横梁,以及两侧的前地板上纵梁和前围纵梁连接形成第一环形加强结构,后地板下部横梁、机舱后段横梁,以及两侧的门槛梁和所述扭力盒连接形成第二环形加强结构。本发明的车身加强结构能够增加车身的结构强度与扭转刚度,并能够提升碰撞时的碰撞力传递效果,而可提升整车安全性。
