The invention provides a vehicle rear floor frame structure. The vehicle rear floor frame structure comprises longitudinal beams arranged on the two sides of a vehicle and a cross beam arranged between the longitudinal beams. The longitudinal beam comprises the front longitudinal beam, the rear longitudinal beam fixedly connected to the rear end of the front longitudinal beam and the connecting longitudinal beam used for being assembled with a vehicle body on a vehicle, the front longitudinal beam, the rear longitudinal beam and the cross beam are of an aluminum structure, the connecting longitudinal beam is of a steel structure, and the connecting longitudinal beam is arranged on the outer side of the front longitudinal beam and the outer side of the rear longitudinal beam. The inventionfurther relates to a vehicle, the front longitudinal beam, the rear longitudinal beam and the cross beam are made of aluminum sheet metal parts, the connecting longitudinal beams are made of steel sheet metal parts, meanwhile, the connecting longitudinal beams are additionally arranged to effectively connect a vehicle body and a vehicle front floor frame structure on the vehicle, and the structural strength and rigidity of a vehicle body rear frame are guaranteed. Meanwhile, the problem that a steel vehicle body is overweight is solved, and the lightweight design of the vehicle body is embodied.

    本发明提供了一种车辆后地板框架结构,包括设于车辆两侧的纵梁和设于所述纵梁之间的横梁,所述纵梁包括前纵梁、固接于所述前纵梁后端的后纵梁和用于与车辆上车体装配的连接纵梁,所述前纵梁、所述后纵梁和所述横梁为铝结构,所述连接纵梁为钢结构,所述连接纵梁设于所述前纵梁与所述后纵梁的外侧。本发明还涉及一种车辆,通过将前纵梁、后纵梁和横梁采用铝钣金件,连接纵梁采用钢钣金件,同时通过增设连接纵梁以有效地连接车辆上车体、车辆前地板框架结构,保证了车身后部框架的结构强度及刚度;同时解决了钢制车身重量超重的问题,体现了车身轻量化的设计。
