Automobile rear wall assembly

Abstract

The invention discloses an automobile rear wall assembly. The automobile rear wall assembly comprises a rear wall inner panel assembly (1); the rear wall inner panel assembly (1) comprises a rear wall inner panel (101), a first rear wall connecting plate (102), a second rear wall connecting plate (103) and a rear wall outer panel (2), wherein the first rear wall connecting plate (102) is connected with a first end of the rear wall inner panel (101), and the second rear wall connecting plate (103) is connected with a second end of the rear wall inner panel (101); and the rear wall inner panel (101), the first rear wall connecting plate (102), the second rear wall connecting plate (103) and the rear wall outer panel (2) enclose a three-dimensional cavity structure. Compared with the existing automobile rear wall with a plate-shaped structure, the automobile rear wall assembly has the advantages that the automobile rear wall assembly is the three-dimensional cavity structure enclosed by the rear wall inner panel assembly and the rear wall outer panel; the torsional rigidity of the automobile rear wall assembly is greatly improved so that the torsional rigidity of an automobile framework is improved, the automobile performance is improved and the service life of the automobile is prolonged. The rear wall inner panel assembly adopts a separated design so that the rear wall inner panel assembly is convenient to 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
