Gas spring mounting reinforcement plate structure and method for assembling gas spring mounting reinforcement plate

Abstract

The invention provides a gas spring mounting reinforcement plate structure which comprises a rear wheel cover assembly, a body-side outer panel, a gutter channel and a rear transverse beam of a roof. The rear wheel cover assembly is welded with the body-side outer panel, the gutter channel and the rear transverse beam of the roof to form a white body and comprises a C-column outer reinforcement plate, a gas spring mounting reinforcement plate, a gas spring mounting nut and a body-side inner panel, and the gas spring mounting reinforcement plate is welded with the gas spring mounting nut, the C-column outer reinforcement plate and the body-side inner panel. The invention further provides a method for assembling the gas spring mounting reinforcement plate. The gas spring mounting reinforcement plate structure and the method have the advantages that the rigidity of gas spring mounting points can be improved, and the gas spring mounting reinforcement plate structure can be guaranteed against deforming or cracking when stern door opening and closing gas spring loads are borne by the gas spring mounting reinforcement plate structure, is reliable and durable and is lightened on the premise that the requirement on the rigidity of the gas spring mounting points is met.

Description

technical field [0001] The invention relates to a car body, in particular to a gas spring installation reinforcing plate structure in the car body and an assembly method of the gas spring installing reinforcing plate. Background technique [0002] The gas spring installation point structure is one of the important structures of the body-in-white. The quality of its structure directly affects the durability and reliability of the body-in-white, the quality and operability of the customer's opening and closing tailgate. If the structure is not good, the rigidity of the mounting point is not enough, which will lead to durable cracking of the body, and the customer can see the cracked solder joints when the tailgate is opened, and even the deformation of the mounting point makes the tailgate unable to open, which directly affects the perceived quality and brand quality. The structure of the traditional car gas spring installation point is as follows Figure 1 to Figure 3 As show...

AI Technical Summary

Problems solved by technology

This structure is easy to withstand the gravity of the tailgate in the durable road test, which will lead to cracking of the water tank or cracking of the solder joints, and the tailgate cannot be opened, and it is a complaint problem that customers can see when opening the door.

[0003] The main disadvantages are: 1. The gas spring is only connected to the flow tank 103, and the rigidity is poor, which is prone to cracking of the solder joints at the installation point of the gas spring and even the problem that the tailgate cannot be opened; 2. When the weight of the tailgate is heavy, It is necessary to make the gas spring installation reinforcement plate 104 large in size, so as to meet the rigidity requirements of the installation point and the tailgate opening. The crossbeam is not connected. When the tailgate opening is poor in rigidity and the joint is weak, it is often strengthened by thickening the water tank 103. The poor connection of the body will easily lead to high stress in the corner area of ​​the water tank 103, resulting in solder joints or sheet metal cracking.
