Description

Technical Field

[0001] This utility model relates to the field of power batteries, specifically a device for testing the hardness of aluminum profiles for power batteries. Background Technology

[0002] In power batteries, aluminum profiles are used as the outer shell or structural components. Aluminum profiles can be formed into complex and robust structures through precision extrusion molding processes. While ensuring strength, thin-walled designs can be achieved, which can significantly reduce the overall weight of the battery, thereby improving the range of new energy vehicles.

[0003] During operation, power batteries need to withstand external forces such as vibration and collision. As the outer shell or structural component, aluminum profiles must have sufficient hardness to resist plastic deformation and prevent damage to the battery module or electrolyte leakage. Therefore, hardness testing devices are used to test the aluminum profiles of power batteries.

[0004] For testing the hardness of aluminum profiles used in power batteries, there are hardness tester frames, Vickers hardness testers, and Brinell hardness testers. Hardness tester frames are the most commonly used, enabling rapid non-destructive testing at production sites, sales sites, or construction sites.

[0005] Currently, when testing the hardness of aluminum profiles for power batteries, the presence of an oil film on the aluminum profile can affect the testing results if this film is not cleaned. Utility Model Content
