[0014] 1. A test seat is slidably connected to the base based on a telescopic sliding assembly, and a floating assembly is set between the lifting assembly and the rolling seat. The floating assembly is provided by setting a floating sleeve at the telescopic end of the lifting assembly and a floating shaft on the rolling seat. A floating spring is fixedly connected between the floating sleeve and the floating shaft. When the charging gun is subjected to a rolling test, the rolling seat is first driven down by the lifting assembly to adjust the distance between the bottom surface of the test wheel and the surface of the test seat. When the telescopic sliding assembly drives the test seat to slide back and forth, the charging gun lifts the test wheel back and forth. At this time, the floating spring is compressed a certain distance, and the elastic force of the floating spring acts on the charging gun through the test wheel, so that the test wheel rolls over the charging gun with a certain pressure. The distance between the bottom surface of the test wheel and the surface of the test seat is increased, and the floating spring is compressed more, and the pressure acting on the charging gun is greater. The pressure value is accurately read by the pressure sensor, thereby simulating the way a vehicle rolls over the charging gun in real life. At the same time, the rotary adjustment assembly is used to drive the rotary test bench to rotate, so as to adjust the relative angle between the charging gun and the test wheel, thereby improving the objectivity and accuracy of the test results.

[0015] 2. The distance between the bottom surface of the test wheel and the surface of the test seat is adjusted by the lifting assembly, so that the expansion and contraction of the floating spring when the test wheel rolls over the charging gun can be adjusted, thereby adjusting the pressure exerted by the test wheel on the surface of the charging gun. The pressure value can be accurately read through the pressure sensor. The pressure adjustment process is more objective and the pressure value can be accurately read, which reduces the number of tests, improves the efficiency and accuracy of the test, and reduces the cost of the test.
