[0044] In the present invention, when the user uses the device, the external preset water spray equipment and blower are connected to the two connectors 31 through hoses, and then the charging interface 8 and the charging gun body 7 are placed in the two circular grooves respectively. With the help of the extension of the telescopic ends of the two first electric telescopic rods 17, the two clamping plates 18 are driven to clamp and fix the charging interface 8 and the charging gun body 7 in the two circular grooves respectively, and ensure that the charging interface 8 and the charging gun body 7 are in the same straight line, and then the two winding rollers 41 are controlled to rotate together, so that the two shielding curtains 4 2 are unfolded downward together until the two counterweights 44 are in contact with the inner bottom surface of the collection box 9, and the multiple electromagnets 12 are controlled to be energized to generate magnetism, and the magnetic strips 43 at both ends of the two unfolded shielding curtains 42 are manually pressed in turn in the direction close to the electromagnets 12, so that the multiple corresponding electromagnets 12 can magnetically fix the multiple magnetic strips 43 respectively, so that after the two ends of the two unfolded shielding curtains 42 are limited and fixed, the charging interface 8 and the charging gun body 7 to be tested are isolated, and the test range of the charging interface 8 and the charging gun body 7 is reduced.

[0045] Then, the two first driving screws 10 can be controlled to rotate synchronously, driving the movable seat 4, the first rotating plate 5, the second rotating plate 6 and other components to move toward the direction close to the fixed plate 2, thereby driving the fixed charging gun body 7 to be inserted into the interior of the charging interface 8, and then the two first driving screws 10 are controlled to reverse synchronously, driving the charging gun body 7 to be pulled out from the interior of the charging interface 8. With the help of relevant instruments and equipment, the force required for the charging gun body 7 to be inserted into the charging interface 8 and pulled out from the interior of the charging interface 8 is monitored in real time, so as to achieve the effect of testing the insertion and extraction force of the charging gun body 7.

[0046] Furthermore, the first rotating plate 5 can be controlled to rotate slightly clockwise or counterclockwise at a certain angle longitudinally on the top of the movable seat 4, and the second rotating plate 6 can be controlled to rotate slightly counterclockwise or clockwise at a certain angle transversely on the top of the first rotating plate 5, and then the two first driving screws 10 are controlled to drive the charging gun body 7 and the charging interface 8 to perform multiple plugging and unplugging tests, thereby simulating the situation in which the charging gun body 7 is manually plugged and unplugged at different angles during actual use of the charging gun body 7, so that the plugging and unplugging force test of the charging gun body 7 is more accurate.

[0047] During actual use, the charging gun body 7 will inevitably encounter an environment with a lot of dust. At this time, after the charging gun body 7 is inserted into the interior of the charging interface 8, there is a gap between the charging gun body 7 and the charging interface 8. The external preset blower can be controlled to start. When the blower conveys wind power to the interior of one of the hollow plates 30 through a hose, dry mud and sand are poured into the interior of the hose, so that the mud and sand can be conveyed to the interior of one of the hollow plates 30 along with the wind power, and discharged downward through multiple nozzles 36 to the surface and gap inside the charging interface 8 and the charging gun body 7, so that the gap between the charging interface 8 and the charging gun body 7 is filled with a sufficient amount of mud and sand, and then the two first driving screws 10 are controlled to drive the charging gun body 7 and the charging interface 8 to be plugged and unplugged multiple times, so as to simulate It is simulated that during the actual use of the charging gun body 7, a large amount of dust in the external environment adheres to the gap between the charging gun body 7 and the charging interface 8, and it is tested whether the accumulated mud, sand and dust will enter the interior of the charging interface 8 as the charging gun body 7 is plugged and unplugged between the charging gun body 7 and the charging interface 8 for many times, and bring adverse effects on the plugging and unplugging of the charging gun body 7, and whether the force required for plugging and unplugging the charging gun body 7 changes. After the charging gun body 7 is pulled out from the charging interface 8, multiple nozzles 36 can directly spray mud and sand on the surface of the charging gun body 7, so that the plugging and unplugging force test data of the charging gun body 7 is more comprehensive and accurate; the excess mud and sand sprayed downward by the multiple nozzles 36 will be isolated by the two unfolded shielding curtains 42, and finally fall into the collection box 9 for temporary storage.

[0048] Moreover, during the actual use of the charging gun body 7, it is also bound to encounter an external rainy environment. At this time, the external blower can be controlled to stop working, and then the external preset water spraying equipment can be controlled to start, so that the multiple nozzles 35 at the bottom of the other hollow plate 30 can spray water on the surface of the charging gun body 7 and the charging interface 8, simulating the scene when the charging gun body 7 encounters rainy weather during actual use, and testing whether the external rainwater will affect the plugging and unplugging force of the charging gun body 7; at this time, the water sprayed onto the surface of the charging gun body 7 and the charging interface 8 can also wash away the mud and sand attached in the previous step, and the water sprayed downward by the multiple nozzles 35 will also be isolated by the two unfolded shielding curtains 42, and finally fall into the collection box 9 for temporary storage.

[0049] When the two hollow plates 30 spray mud and water onto the surfaces of the charging gun body 7 and the charging interface 8 in turn to simulate the actual use scenario of the charging gun body 7, the first servo motor preset inside the second slider 33 can be controlled to drive the two hollow plates 30 to rotate forward and reverse, so that multiple nozzles 36 and multiple nozzles 35 can spray mud and water onto the surfaces of the charging gun body 7 and the charging interface 8 from different angles, so that the mud and water can be more comprehensively attached to the surfaces of the charging gun body 7 and the charging interface 8, thereby improving the accuracy of the test.

[0050] When water is sprayed on the surface of the charging gun body 7 and the charging interface 8 for the test, the water falling into the collecting box 9 will come into contact with the mud and sand previously tested, and as the moving seat 4 continues to move on the top of the collecting box 9, the push plate 19 and the multiple sealing plates 21 in the multiple through slots 20 that rotate in an open state move back and forth inside the collecting box 9, which has a mixing effect on the mud and water. At this time, the telescopic end of the second electric telescopic rod 14 can be controlled to retract, driving the sealing block 15 to be stored in the rectangular groove 13, and the first rotating plate 5 can be controlled to drive the charging gun body 7 to rotate downward on the top of the moving seat 4, so that the charging gun body 7 can be charged. The electric gun body 7 enters the interior of the collecting box 9, and there is mud and water on the surface. Then the first rotating plate 5 is controlled to drive the charging gun body 7 to rotate upward and reset, and the two first driving screws 10 are continued to be controlled to drive the charging gun body 7 to perform plugging and unplugging force tests with the charging interface 8 for many times to simulate the scene when the charging gun body 7 is used in the external environment, the charging gun body 7 falls to the ground, and is picked up and used without wiping. It tests whether the mud and water in the external environment attached to the surface of the charging gun body 7 will affect the plugging and unplugging of the charging gun body 7, further improve the comprehensiveness of the plugging and unplugging force test of the charging gun body 7, and ensure that the test results are highly credible.

[0051] After the test of simulating muddy water adhesion on the charging gun body 7 is completed, the multiple nozzles 35 above can be controlled to spray water downward to rinse the charging gun body 7 and the charging interface 8, and then the multiple nozzles 36 can be controlled to spray air without mud and sand on the surface of the charging gun body 7 and the charging interface 8 to clean and dry the charging gun body 7 and the charging interface 8. Then, the two third sliders 40 can be controlled to drive the rectangular plate 27 to slide outward from the inside of the moving frame 26, and the rectangular plate 27 can be controlled to rotate upward to a vertical state, and the preset heating block inside the rectangular plate 27 can be controlled to be energized to generate heat, and then the two first driving sliders 40 can be controlled to drive the rectangular plate 27 to slide outward from the inside of the moving frame 26, and the rectangular plate 27 can be controlled to rotate upward to a vertical state, and the heating block preset in the rectangular plate 27 can be controlled to be energized to generate heat, and then the two first driving sliders 40 can be controlled to drive the rectangular plate 27 to slide outward from the inside of the moving frame 26. The movable screw 10 drives the charging gun body 7 to move toward the charging port 8, so that the rectangular plate 27 in a vertical state is located between the charging gun body 7 and the charging port 8. The heat generated by the rectangular plate 27 will simultaneously heat the charging gun body 7 and the charging port 8, thereby simulating the high temperature generated by the charging gun body 7 and the charging port 8 during the charging process, or the scenario of use in hot weather, to test whether the high temperature affects the plugging and unplugging of the charging gun body 7, and whether the charging gun body 7 will deform itself after multiple plugging and unplugging in a high temperature environment, resulting in changes in the plugging and unplugging force.

[0052] It is even possible to control the rectangular plate 27 to rotate downward to a vertical state after the rectangular plate 27 heats the charging gun body 7 and the charging interface 8, and then control the second driving screw 37 to drive the moving frame 26 and the rectangular plate 27 to move downward synchronously, so that the rectangular plate 27 can enter the interior of the collection box 9 to heat the muddy water inside the collection box 9. While the muddy water inside the collection box 9 is being heated, the two first driving screws 10 still drive the moving seat 4 and other components to move back and forth together, so that the push plate 19 continues to stir the muddy water inside the collection box 9 back and forth, which can increase the contact area between the muddy water and the air, thereby accelerating The transfer of heat helps to improve the heating efficiency of the rectangular plate 27 on the muddy water, so that the muddy water can reach the boiling point faster. The muddy water will produce more water vapor in the process of continuous heating, and the water vapor will move upward, so that the two unfolded shielding curtains 42 can isolate the water vapor, and create a high temperature and high humidity use environment for the charging gun body 7 and the charging port 8 that are undergoing the plugging and unplugging force test, and test whether the high temperature and high humidity environment has an impact on the plugging and unplugging of the charging gun body 7, further improve the comprehensiveness of the plugging and unplugging force test of the charging gun body 7, and simulate the plugging and unplugging of the charging gun body 7 in a variety of use environments.

[0053] After the test of the charging gun body 7 is completed, the inner walls of the two unfolded shielding curtains 42 will inevitably be attached with mud and sand. After the moving seat 4 and other multiple components are moved and reset to the original state, the first servo motor is controlled to drive the two hollow plates 30 to rotate toward one of the shielding curtains 42, so that the multiple nozzles 35 are directed toward one of the shielding curtains 42, and the external preset water spraying equipment is controlled to continue to start, so that the multiple nozzles 35 can spray water on the inner wall of one of the shielding curtains 42, first wash the mud and sand attached to the inner wall of one of the shielding curtains 42, and as the first slider 28 is in the first slide groove 22, the water is sprayed on the inner wall of the shielding curtain 42. It moves back and forth inside, so that it can flush the inner wall of one of the shielding curtains 42 horizontally and comprehensively. While multiple nozzles 35 flush the inner wall of one of the shielding curtains 42, multiple electromagnets 12 are controlled to be powered off to release the magnetic fixation of the two magnetic strips 43, and the winding roller 41 is controlled to slowly wind up one of the shielding curtains 42, so that multiple nozzles 35 can flush the inner wall of one of the shielding curtains 42 vertically and comprehensively, ensuring that the shielding curtain 42 is cleaned more cleanly. The other shielding curtain 42 can also repeat the above-mentioned cleaning steps for cleaning, which is convenient for the subsequent use of the two shielding curtains 42.

[0054] After flushing the two shielding curtains 42, the flushing water will also fall into the interior of the collection box 9 for centralized collection. The sealing plates 21 inside the multiple through grooves 20 can be controlled to rotate to a horizontal state, and the multiple through grooves 20 can be sealed. After the valves inside the two discharge pipes 11 are controlled to open, the two first driving screws 10 are controlled to continue to drive the moving seat 4 to move back and forth on the top of the collection box 9, so that the push plate 19 can push the muddy water inside the collection box 9, accelerate the discharge of muddy water from the inside of the collection box 9, and improve the discharge efficiency of muddy water.
