It should be noted that the cabinet 1 of the present invention further includes corresponding electrical components for implementing the charging function of the new energy vehicle, and these components are omitted in the drawings for convenience of illustration only.

The working principle is as follows:

in the first step, the user unscrews the cover plate 6, at this time, the PLC controller 9 detects that the cover plate 6 is unscrewed through the angle sensor on the dual-axis servo motor 29, the PLC controller 9 immediately instructs the touch display screen 4 to light up, and the PLC controller 9 instructs the booster pump 25 to work, so that the air pressure at the touch display screen 4 is greater than the external air pressure (it is worth noting that the self-starting pressure valve 27 is in a non-conducting state in the process).

Secondly, the user performs corresponding operation on the touch display screen 4;

in the third step, the user takes off the charging gun 15 and releases the charging wire 16, then inserts the charging gun 15 into the charging port on the new energy automobile, and then the user clicks on the touch display screen 4 to start charging.

And fourthly, the user completely closes the cover plate 6, at the moment, the PLC 9 detects that the cover plate 6 is completely closed through the angle sensor on the double-shaft servo motor 29, the PLC 9 immediately instructs the touch display screen 4 to close, and simultaneously instructs the booster pump 25 to stop working.

And fifthly, after the charging is finished, the user unscrews the cover plate 6, performs corresponding operation on the touch display screen 4 to stop charging, then scans code payment through the scanning port, then the user inserts the charging gun 15 on the gun head groove 13 and winds the charging wire 16 on the winding frame 20, and finally the cover plate 6 is closed.

It should be noted that during the above-mentioned fourth step to fifth step, the user can briefly light up the touch display screen 4 through the status button 57, so as to view the contents on the touch display screen 4 without opening the cover 6.

When the user forgets to close the cover plate 6, the PLC controller 9 will automatically instruct the dual-axis servo motor 29 to operate to completely cover the cover plate 6 at the notch of the groove 3; the judgment is based on that the cover plate 6 is in the unscrewing state (the angle sensor on the double-shaft servo motor 29 provides a data source) and no obstacle exists on the rotating path of the cover plate 6 for a long time (the infrared transmitter 11 and the infrared receiver 12 provide a data source); in the process, the PLC 9 can detect whether an obstacle exists on a path in real time through the cooperation of the infrared transmitter 11 and the infrared receiver 12, so that the hand of a user is prevented from being clamped by mistake.

It is to be noted that the PLC controller 9 monitors the temperature and humidity conditions of the space area at the touch display screen 4 in real time through the second temperature and humidity sensor 55; when the temperature at the position is lower, the PLC 9 instructs the heat preservation lamp 56 to start to heat and preserve the temperature of the area at the position; when the humidity of this department was too high, PLC controller 9 instruction booster pump 25 work to dehumidify this department region under the cooperation of dry subassembly, this in-process simultaneously, accuse temperature subassembly and pressure boost subassembly can also cooperate and assist the cooling to this department region.

It is worth noting that the PLC controller 9 monitors the temperature and humidity inside the cabinet 1 in real time through the first temperature and humidity sensor 47; when the humidity inside the cabinet body 1 is high, the PLC 9 instructs the drying pump 46 to increase the power, so as to rapidly dehumidify the inside of the cabinet body 1; when the temperature inside the cabinet 1 is high, the PLC controller 9 instructs the airflow circulation fan 36, the semiconductor cooling device 8, and the cooling fan 59 to increase the power, thereby rapidly cooling the inside of the cabinet 1.

It is worth noting that the operating principle of the drying assembly is: the two drying boxes 41 are in a state of alternating circulation type operation, that is:

s1, the PLC 9 instructs the box cover 48 of one drying box 41 to open and the box cover 48 of the other drying box 41 to remain closed, and the solenoid valves 51 of the input branch pipe 49 and the output branch pipe 50 of the drying box 41 with the box cover 48 in the open state are both in the open state, and the solenoid valves 51 of the input branch pipe 49 and the output branch pipe 50 of the other drying box 41 are both in the closed state.

S2, the PLC controller 9 instructs the drying pump 46 to operate, so that the water absorption beads 44 inside the drying box 41 with the box cover 48 in the open state can sufficiently absorb the moisture in the air inside the cabinet 1.
