Description

Technical Field

Background Art

[0002] Before the electric step assembly leaves the factory, it is necessary to simulate the actual loading state to test whether the telescopic function is normal, and whether there is any abnormal noise during the operation of the step, or whether the operating decibel exceeds the customer's requirements. The traditional detection method is to manually flip the step and manually install it on the test bench, and then control the step extension and retraction through buttons, while testing the decibel of the step operation and testing whether there is any abnormal noise by ear.
