The passive lock hook will move upward 0.2mm for each grid movement, and then the claw locking operation is performed until the data result meets the requirements; Step S5: Perform a locking mechanism performance test. Select the motor locking mode in the test operation interface. The product motor will drive the claw to lock until it is locked in place and then stop. Record all test data at this time. After the recording is completed, select the motor unlocking mode in the test operation interface. The product motor will drive the claw to unlock until it is fully unlocked and stop, and record the test data at this time; During the entire test process, the temperature control module monitors the ambient temperature in real time. When the ambient temperature is less than 0°C, it automatically heats up to the normal operating temperature of the equipment and maintains it.

9. The method for using the locking mechanism performance testing device according to claim 8, characterized in that: In step S2, during the performance test, the unlocking mode is selected through the interface display module to move the claw to the unlocking position set for the product, and then the locking mode is selected to drive the claw to move to the locking position set for the product and stop. The data management module collects, stores, processes and displays the test data of various parameters during the entire test process in real time.

10. The method for using the locking mechanism performance testing device according to claim 8, characterized in that: The performance test module in step S3 can control the product motor instructions and parameters, and monitor the product motor running status in real time, collect various test data in real time through the data management module and store and process them, and the test data is displayed in real time through the interface display module; The passive lock hook position adjustment tool in the test tool can be accurately adjusted according to the test requirements, and the position of the passive lock hook meets the test requirements.
