Abstract

The invention provides a vehicle body rear structure. The vehicle body rear structure comprises a rear wheel cover outer plate; the rear wheel cover inner plate is arranged opposite to the rear wheelcover outer plate and connected with the rear wheel cover outer plate in a matched mode; the lower edge part of the rear suspension mounting plate is connected with the upper edge part of the rear wheel cover inner plate, and the side edge part of the rear suspension mounting plate is connected with the inner wall of the rear wheel cover outer plate; and the rear suspension reinforcing plate is arranged in the rear suspension mounting plate, the lower edge part of the rear suspension reinforcing plate is connected with the upper edge part of the rear wheel cover inner plate, and the rear suspension reinforcing plate forms a first columnar cavity between the rear wheel cover inner plate and the rear wheel cover outer plate. According to the rear structure of the vehicle body, through reasonable structural design, the problems of poor rigidity, strength and NVH (Noise Vibration and Harshness) performance of back-sliding type vehicles, steel-aluminum hybrid vehicles, vehicles without cross beams on rear floors and other types of vehicles are well solved while structural light weight is considered. The invention further provides a vehicle comprising the vehicle body rear structure.

Description

technical field [0001] The invention relates to the technical field of automobile bodies, in particular to a body rear structure and an automobile. Background technique [0002] At present, the rapid development of the automobile industry has led to higher and higher requirements for vehicle NVH (comfort). Among them, the rear structure of the car plays a key role in improving the bending, torsional mode, stiffness and NVH performance of the car. [0003] Among the existing automobiles, especially those with fastback models, steel-aluminum mixed body and no crossbeam on the rear floor, due to the limitation of the layout of the body structure, their bending, torsional stiffness, strength and shock absorption performance are often relatively poor. For technicians in the automotive field, how to optimize the rear structure of the body to improve the bending, torsional mode, stiffness and NVH performance of the vehicle while taking into account the lightweight structure is a d...
