Place the power plug and vehicle plug with the manufacturer's recommended cable on the cement floor randomly, and apply a pressure of 11000 ± 500N at a speed of (8 ± 2) km/h to press over the power plug or vehicle plug (tire inflation pressure 220 ± 10 kPa),

To test the ability of power supply or vehicle plugs to withstand crushing. Automobile tire rolling test device according to standard GB/T20234.1-2011

A steel frame with surface electrostatic spraying is used to form the frame, and the bottom plate simulates a cement floor. The rolling mechanism can simulate a car rolling an object and sliding up and down freely. The plug can withstand the same pressure and is equipped with limit protection,

Another set of driving devices drives the rolling mechanism to achieve forward and backward rolling actions, with the main components made of stainless steel and aluminum.
