Description

Technical Field

[0001] The utility model relates to the field of automobile parts, and particularly relates to a sealing stamping cover plate with strong protection performance. Background Technique

[0002] The battery module is the most important component in an electric vehicle, which includes battery modules, a battery management system, a battery protection system, connectors and other parts. Among them, the battery protection system is mainly composed of a battery tray and a cover plate. Both play a role in protecting the battery module and preventing damage to the battery module caused by impact. In order to improve the vehicle performance, the existing trays and cover plates are made of aluminum materials.

[0003] Traditional cover plates are made by die-casting process. Die-cast aluminum plates have the characteristics of high strength, high rigidity and wear resistance. However, since their forming process is to inject molten aluminum alloy material into the mold under high pressure for forming, they have the characteristic of complex forming, resulting in low production efficiency and high production cost. Therefore, many manufacturers have used the stamping process to replace the traditional die-casting process. Although the stamping cover plate made by the stamping process is lighter in weight, lower in production cost and lower in production difficulty, due to the problem of its thin material thickness, the sound insulation function decreases after using the stamping cover plate. The battery module will generate greater noise during the driving of the electric vehicle, affecting the driving experience of the vehicle. To solve this problem, a new type of cover plate is needed to solve this problem. Content of the Utility Model

[0004] The utility model is to solve the technical problems proposed in the above background, and the following technical solutions are proposed:

[0005] A sealing stamping cover plate with strong protection performance, including a stamping cover plate. A sealing strip groove is arranged at one side edge of the stamping cover plate. A sealing strip is arranged in the sealing strip groove. The stamping cover plate is provided with a plurality of fixing holes, and the plurality of fixing holes are located outside the sealing strip groove. A plurality of positioning columns are arranged on one side of the stamping cover plate, and the plurality of positioning columns are located inside the sealing strip groove. A heat insulation plate is arranged on one side of the stamping cover plate. A plurality of first positioning holes are arranged on the heat insulation plate, and the positions and sizes of the plurality of first positioning holes correspond to the positions and sizes of the positioning columns. An insulating plate is arranged on the heat insulation plate. A plurality of second positioning holes are arranged on the insulating plate, and the positions and sizes of the plurality of second positioning holes correspond to the positions and sizes of the positioning columns.

[0006] Preferably, the insulating plate has a sound insulation function.

[0007] Preferably, a plurality of reinforcing ribs are arranged on the other side of the stamping cover plate.

[0008] Preferably, the reinforcing ribs are of semi-cylindrical structure.

[0009] Preferably, the reinforcing ribs are distributed in a crisscross pattern on the other surface of the stamping cover plate.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. By setting the stamping cover plate to replace the traditional die-cast cover plate, the weight of the cover plate is lighter, the manufacturing cost is lower, the manufacturing efficiency is higher, and the sealing performance is better. By setting the heat insulation plate with sound insulation function and arranging the insulating plate on the insulating plate, the noise generated when the automotive battery module is working can be reduced, and at the same time, the heat emitted when the battery module is working can be further isolated, improving the comfort of the passengers and drivers.

[0012] 2. By arranging the reinforcing ribs on the stamping cover plate, the strength of the stamping cover plate can be effectively improved, effectively alleviating the deformation and fracture of the stamping cover plate during a collision, and further protecting the safety of the passengers and drivers.
