Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] like Figures 1-2 As shown, this application provides a power battery cover plate strength testing device, including a test box 1, which is set in a power battery processing plant and is used to perform strength testing on the power battery after production to ensure the strength of the cover plate;

[0024] The test box 1 has an internal cavity 11 for holding the battery cover to be tested. A pressure assembly 2 is provided on the top of the test box 1. The pressure assembly 2 includes a mounting bracket 21, which is installed above the cavity 11. A cylinder 22 is fixedly installed on the top of the mounting bracket 21. The output end of the cylinder 22 passes through the mounting bracket 21 and is connected to a pressure sensor 23 via a coupling. The pressure sensor 23 is used to transmit test data. A punch head 24 is fixedly installed at the bottom of the pressure sensor 23. The punch head 24 is used to apply pressure to the battery cover to test the maximum pressure that the battery cover can withstand.

[0025] When the test needs to be carried out, first, the power battery cover to be detected is placed in the accommodating cavity 11, and then the air cylinder 22 is started, so that the air cylinder 22 drives the pressure sensor 23 and the stamping head 24 to move downward together, so that the stamping head 24 gradually approaches and contacts the battery cover and exerts pressure on the battery cover, at this time, the pressure sensor 23 measures and records the size of the pressure in real time, and transmits the data to the external data processing system, and when the battery cover cannot bear more pressure and is deformed or broken, the test is ended, at this time, the maximum pressure value that the battery cover can bear can be known through data analysis, and whether the strength of the battery cover meets the requirements can be evaluated.
