Auto rear wall assembly

Abstract

The invention discloses an automobile rear wall assembly. The rear wall assembly of the automobile comprises: a rear wall inner panel assembly (1); the rear wall inner panel assembly (1) includes a rear wall inner panel (101); and the second rear wall inner panel (101) a first rear wall connection plate (102) connected at one end; and a second rear wall connection plate (103) connected to the second end of the rear wall inner panel (101); and a rear wall outer panel (2); The rear wall inner panel (101), the first rear wall connecting plate (102) and the second rear wall connecting plate (103) form a three-dimensional cavity structure with the rear wall outer panel (2). Compared with the existing plate-shaped automobile rear wall, the automobile rear wall assembly provided by the present invention is a three-dimensional cavity structure synthesized by the rear wall inner panel assembly and the rear wall outer panel, which greatly improves the automobile rear wall assembly. The torsional rigidity of the car is improved, thereby improving the torsional rigidity of the car frame, improving the performance of the vehicle and prolonging the service life of the car. The rear wall inner panel assembly adopts a split design to facilitate manufacture.

Description

technical field [0001] The invention relates to an automobile rear wall assembly. Background technique [0002] The rear wall of the car is an important part of the car frame. The torsional stiffness of the rear wall of the car directly affects the torsional stiffness of the car frame. In other words, the torsional rigidity of the rear wall of the car is weak, which makes the torsional rigidity of the car frame relatively weak. [0003] The rear wall of the automobile in the prior art is mostly made of a single-layer metal plate with a plate structure, and the torsional rigidity of the rear wall of the automobile is low. The torsional rigidity of the rear wall of the car is low, so that the car has a low mode, and the noise, vibration and harshness (NVH) performance of the car is poor. When the car is driving on an uneven road, the rear area of ​​the car is easily deformed, that is, the car frame is deformed, which increases the fatigue damage of the car body and affects ...

In other words, the torsional rigidity of the rear wall of the car is weak, making the torsional rigidity of the car frame relatively weak

[0003] The back wall of the car in the prior art is mostly made of a single-layer metal plate, and the torsional rigidity of the car back wall is low.

The torsional rigidity of the rear wall of the car is low, so that the car has a low mode, and the performance of the car's noise, vibration and harshness (NVH) is poor

When the car is driving on an uneven road, the rear area of ​​the car is easily deformed, that is, the car skeleton is deformed, which increases the fatigue damage of the car body and affects the performance of the whole car and the service life of the car
