[0002] Car air conditioners typically undergo lifespan testing before leaving the factory. Since cars frequently travel on various bumpy roads, the shock resistance of the devices installed on them is particularly important. During the testing process, workers often place the car air conditioner in a container and manually shake it repeatedly to test its shock resistance. This testing method is labor-intensive, inefficient, and impractical. Summary of the Invention
