The invention relates to the technical field of automobiles, in particular to an automobile and a rear floor framework assembly thereof, and aims to solve the problems that an existing automobile rear floor framework assembly cannot meet the rear high-low speed collision requirement of the automobile, and the strength, durability and torsional rigidity need to be improved. In order to achieve the purpose, the rear floor framework assembly comprises a left longitudinal beam structure, a right longitudinal beam structure, a front cross beam, a middle cross beam, a rear cross beam, a middle left longitudinal beam structure and a middle right longitudinal beam structure, and a left Y-shaped force transmission structure and a right Y-shaped force transmission structure are formed. A first left reinforcing structure and a second left reinforcing structure which extend upwards and are arranged side by side are arranged on the left longitudinal beam structure, and a first right reinforcing structure and a second right reinforcing structure which extend upwards and are arranged side by side are arranged on the right longitudinal beam structure. The problem of rear collision of the automobile can be solved, personnel safety in the rear collision process of the automobile is effectively protected, the strength, durability and torsion performance of the automobile are improved, and the automobile body structure is simplified.

    本发明涉及汽车技术领域,具体提供一种汽车及其后地板骨架总成,旨在解决现有汽车后地板骨架总成无法满足汽车的后高低速碰撞要求以及强度耐久性能和扭转刚度还需要提升的问题。为此目的,本发明的后地板骨架总成,后地板骨架总成包括左纵梁结构、右纵梁结构、前横梁、中横梁、后横梁、中左纵梁结构和中右纵梁结构,并构成了左Y型传力结构和右Y型传力结构,左纵梁结构上设置有向上延伸且并排设置的第一左加强结构和第二左加强结构,右纵梁结构上设置有向上延伸且并排设置的第一右加强结构和第二右加强结构。本发明能够解决汽车后碰撞问题,有效地保护汽车后碰撞过程中的人员安全,提高汽车的强度耐久性能和扭转性能,简化车身结构。
