The invention provides an automobile body and an automobile. The automobile body comprises a rear floor lower cross beam located at the bottom of a rear floor assembly, threshold beams arranged on the left side and the right side correspondingly, and torsion boxes connected to the rear ends of front cabin longitudinal beams on the left side and the right side correspondingly. The rear floor lower cross beam is in a C shape with a forward opening, and the left side and the right side of the rear floor lower cross beam are connected with the rear ends of the doorsill beams on the corresponding sides respectively. The torsion box on each side is connected with the front end of the threshold beam on the same side, and a cabin rear section cross beam is connected between the torsion boxes on the two sides; 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 an annular structure. According to the automobile body of the automobile, the strength and rigidity of the front portion of the rear floor assembly can be improved, the structural strength and torsional rigidity of the bottom of the automobile body can be improved, an annular force transmission channel is formed in the bottom of the automobile body, transmission and dispersion of collision force are facilitated, and the collision safety of the whole automobile is improved.

    本发明提供了一种汽车的车身及汽车,本发明的汽车的车身包括位于后地板总成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;后地板下部横梁呈开口朝前的“C”字型,且后地板下部横梁的左右两侧分别与对应侧门槛梁的后端相连;各侧扭力盒与同侧门槛梁的前端相连,且两侧扭力盒之间连接有机舱后段横梁;后地板下部横梁、机舱后段横梁,以及两侧的门槛梁和扭力盒连接形成环形结构。本发明的汽车的车身,能够增加后地板总成前部位置的强度与刚度,也能够提升车身底部的结构强度与扭转刚度,以及在车身底部形成环形传力通道,有助于碰撞力的传递分散,而有利于提升整车的碰撞安全性。
