Embodiment Construction

[0063] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. For example, although the present invention is described in conjunction with electric vehicles, the technical solution of the present invention can obviously also be applied to traditional fuel (such as gasoline or diesel)-powered vehicles, or hybrid vehicles, etc. Modifications do not constitute a limitation of the invention.

[0064] Based on the problems pointed out by the background technology that the existing electric vehicles cannot meet the high and low speed collision requirements at the rear of the vehicle when the wheelbase is long and the rear overhang is short, and the strength, durability and torsional rigidity of the vehicle need ...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of automobiles, and specifically provides an automobile and its rear floor frame assembly. Background technique [0002] The rear floor of the car is an important part of the car body. It together with the front floor constitutes the floor structure of the car. The rear floor of the car generally includes the rear floor frame assembly, the rear floor panel As a load-bearing structure that carries the rear seat and trunk of the car, it has very high requirements for torsional rigidity, strength and durability, and also plays a vital role in the rear collision of the car. [0003] In the prior art, the left and right sides of the automobile frame assembly each pass a longitudinal beam structure to undertake the transmission of the structural force during a rear collision, so the rear energy-absorbing structure connected to it is usually longer to ensure the energy-absorbing effect, but this method Will increa...
