Rear wall inner plate structure and rear wall plate mounting mechanism

Abstract

The invention provides a rear wall inner plate structure and a rear wall plate mounting mechanism. The rear wall inner plate structure comprises an inner plate mechanism and a supporting plate mechanism. The supporting plate mechanisms are located at the two ends of the inner plate mechanism and connected with the inner plate mechanism, first through groove sets are formed in the supporting plate mechanisms, and second through groove sets are formed in the inner plate mechanism; the supporting plate mechanism and the inner plate mechanism are integrally formed. The rear wall plate mounting mechanism comprises a rear wall inner plate structure; the wing plate is connected with the rear wall outer plate; the wing plates are arranged at the two ends of the connecting supporting plate part, and the rear wall outer plate is arranged on the rear inner plate part and connected with the connecting supporting plate part. According to the rear wall inner plate, the inner plate mechanism and the supporting plate mechanism can be formed at the same time only through one set of mold, the cost of the mold can be greatly reduced, connecting traces are not reserved between the connecting supporting plate part and the rear inner plate part through integral forming, and the structural strength of the rear wall inner plate is improved.

Description

technical field [0001] The invention relates to the field of vehicle manufacturing, in particular to a rear wall inner panel structure and a rear wall panel installation mechanism. Background technique [0002] The back panel of the car is located at the rear of the car. As the most important part of the car body, it plays a vital role in the collision. Under the collision of the whole vehicle at a certain speed, the back panel is impacted and deformed to absorb energy. , in order to ensure the safety of passengers. It is also responsible for ensuring the safety of the trunk of the car in the car, and avoiding large damage to the parts at the rear of the car due to the large deformation of the bottom plate when it is collided. [0003] In the prior art, the rear panel is generally welded by the inner panel of the rear panel, the connecting plate and the braces at both ends, and then the welded rear panel is welded to the vehicle frame. It is welded with the inner panel of ...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a rear wall inner panel structure to solve the technical problem of high mold cost due to the need to prepare multiple sets of molds in advance

[0007] The present invention also provides a rear panel installation mechanism to solve the technical problem that the strength of the rear panel is affected due to too many welding spots, thereby affecting the torsional rigidity of the vehicle
