The invention relates to the technical field of automobiles, and provides a rear floor framework assembly structure and an automobile. The rear floor framework assembly structure comprises a first cross beam, a second cross beam, a third cross beam, a fourth cross beam and a pair of longitudinal beam assemblies, the pair of longitudinal beam assemblies are arranged in parallel, and the first cross beam, the second cross beam, the third cross beam and the fourth cross beam are arranged between the pair of longitudinal beam assemblies in parallel and are connected with the pair of longitudinal beam assemblies; a cavity is formed between the third cross beam and the pair of longitudinal beam assemblies and between the fourth cross beam and the pair of longitudinal beam assemblies. According to the rear floor framework assembly structure, the cavity is formed between the third cross beam and the fourth cross beam, cost increase caused by filling of the spare tire groove is avoided, meanwhile, after spare tire groove sheet metal parts are not arranged, the cost for designing spare tire groove sheet metal part molds can be saved, the manufacturing cost of a vehicle is reduced, and the manufacturing cost of the vehicle is reduced. And meanwhile, the requirement of a user for removing the spare tire is met.
本发明涉及汽车技术领域,提供一种后地板骨架总成结构及汽车。上述的后地板骨架总成结构,包括:第一横梁、第二横梁、第三横梁、第四横梁和一对纵梁总成;一对所述纵梁总成平行设置,所述第一横梁、所述第二横梁、所述第三横梁和所述第四横梁平行设置于一对所述纵梁总成之间并与一对所述纵梁总成连接;所述第三横梁、所述第四横梁与一对所述纵梁总成之间形成空腔。上述的后地板骨架总成结构,通过将第三横梁、第四横梁之间设置为空腔,避免了对备胎槽进行填充导致的成本增加,同时,不设置备胎槽钣金件后,也可省去设计备胎槽钣金件模具的费用,进而降低车辆的制造成本,同时满足了用户对去备胎的需求。
