[0074] The charging gun 21 includes a gun plate 28, the front end of the gun plate 28 is fixedly connected to a handle 29, and a third device slot and a transmission slot are provided inside the handle 29, the inside of the third device slot is fixedly connected to a first motor 30, the output end of the first motor 30 is rotatably connected to a worm 31, and the inside of the transmission slot is rotatably connected to a double-headed screw 32, the center of the surface of the double-headed screw 32 is fixedly connected to a worm gear 33, the surface of the worm gear 33 is meshed with the surface of the worm 31, and both sides of the surface of the double-headed screw 32 are slidably connected to a movable plate 34, and a limiting slot is provided in the center of the movable plate 34, and a connecting plate 35 is fixedly connected to the side of the movable plate 34 close to the center of the gun plate 28, and a clamping plate 36 is fixedly connected to the side of the movable plate 34 away from the center of the gun plate 28. The charging head group 26 includes a charging head 52, and a connecting column 53 is fixedly connected above the charging head 52. The inner diameter of the connecting column 53 is larger than that of the outer diameter of the transmission rod 38, and a clamping groove is provided on the surface of the connecting column 53.

[0075] The operation of the first motor 30 allows the worm 31 to rotate, and then the worm gear can move away, so that the worm gear 33 drives the double-headed screw 32 to rotate, and the movable plate 34 can move inward and outward. When the movable plate 34 moves inward, the connecting plate 35 can be connected to the fixing groove opened by the connecting column 53, and when the movable plate 34 moves outward, the card plate 36 can be connected to the card plate groove opened by the head-changing box body 19.

[0076] A movable groove is provided at the bottom of the transmission groove, and a limiting rod 37 is fixedly connected to the inside of the movable groove. The outer diameter of the limiting rod 37 is adapted to the inner diameter of the limiting groove. The limiting rod 37 adapted to the inner diameter of the limiting groove enables the limiting rod 37 to limit the movable plate 34, thereby preventing the movable plate 34 from deflecting. A transmission rod 38 is fixedly connected to the bottom of the gun plate 28.

[0077] The head changing assembly 24 includes a second motor 47, the output end of the second motor 47 is rotatably connected to a rotating rod 48, the top plate of the outer diameter of the rotating rod 48 is fixedly connected to a rotating disk 49, and a clamping head slot is opened on the top circumference of the rotating disk 49.

[0078] The moving head assembly 25 includes an electric telescopic rod 50, and a guide plate 51 is fixedly connected to the top of the electric telescopic rod 50. The operation of the electric telescopic rod 50 allows the guide plate 51 to move up and down, thereby allowing the guide plate 51 to generate an up and down force on the charging head 52 included in the charging head group 26. When the charging head 52 moves upward, the charging head 52 can be brought into contact with the transmission rod 38.

[0079] like Figure 5 、 Figure 6 and Figure 9 As shown, a heat dissipation cavity and a first device cavity are provided inside the charging box body 17. An electric control component 22 is fixedly connected to the bottom of the first device cavity. The electric control component 22 includes a function board 39. The front end of the function board 39 is respectively provided with a fixedly connected circuit controller 40, a power transmitter 41, a temperature detector 42, a first data controller 43, a second data controller 44, a power connector 45 and a battery 46. Specifically, the rear end of the power connector 45 is connected to a charging plug, which can be connected to an external socket, and then power can be transmitted to the device connected to the function board 39. The front ends of the first data controller 43 and the second data controller 44 are both connected to the power transmission line, so that after receiving power, they can drive the display 18 and the shooting device 27 to work. After receiving power, the power transmitter 41 can transmit power to the handle 29, and then apply power to the charging head 52 through the transmission rod 38. , so that after the charging head 52 is connected to the charging port of the vehicle, the charging head 52 can charge the vehicle, and the temperature detector 42 can detect the liquid temperature inside the heat dissipation cavity after receiving power. The power transmitter 41, the first data controller 43 and the second data controller 44 are respectively connected to the handle 29, the vehicle acquisition module 2 and the shooting device 27 by lines. One end of the temperature detector 42 passes through the first equipment cavity and extends to the interior of the heat dissipation cavity. A piston 23 is installed on one side of the heat dissipation cavity. A liquid inlet groove is provided on the top of the heat dissipation cavity. The opening of the liquid inlet groove allows liquid to enter the interior of the heat dissipation cavity, and then the device inside the heat dissipation cavity can be cooled by the liquid. After the piston 23 is pulled out, the liquid inside the heat dissipation cavity can be discharged. The front end of the first equipment cavity is fixedly connected to the shooting device 27. The operation of the shooting device 27 can take pictures of the vehicle at the front end of the device.

[0080] In summary, when the Internet of Things parking charging billing system and its charging device are in the process of parking by the user, the camera unit 6 can drive the camera 27 to operate, and then the camera 27 can take a picture of the parked vehicle, and then the vehicle camera extraction unit 7 and the vehicle model extraction unit 8 can extract the license plate and model of the vehicle photographed by the camera 27, and then the vehicle position detection unit 9 can calculate the distance between the vehicle and the device, and finally the data sorted by the vehicle camera extraction unit 7, the vehicle model extraction unit 8 and the vehicle position detection unit 9 are transmitted to the Internet of Things 1, wherein the transmission of the model data allows the device to obtain the model of the charging head corresponding to the vehicle by searching the network, and then transmit the model of the charging head to the circuit control module 5, and the transmission of the license plate data allows the user to obtain the location of the parked vehicle by searching the network, thereby preventing the user from spending time looking for the vehicle later, and the transmission of the vehicle distance data can remind the user when the user has not parked the vehicle;

[0081] During this process, when the model of the charging head is transmitted to the circuit control module 5, the second motor 47 can be operated through the circuit control module 5, so that the rotating rod 48 can drive the rotating disk 49 to rotate, so that the charging head group 26 can be located directly below the transmission rod 38, and then the electric telescopic rod 50 is operated so that the guide plate 51 can push the charging head group 26 to the transmission rod 38, so that the bottom of the transmission rod 38 can contact the top of the charging head 52 included in the charging head group 26, and then the first motor 30 is operated to rotate the worm 31, and then the worm gear 33 can drive the double-headed screw 32 to rotate, so that the movable plate 34 can move inward, so that the connecting plate 35 can be engaged and fixed with the connecting column 53 included in the charging head group 26, so that the equipment can automatically change heads.

[0082] When the Internet of Things parking charging billing system and its charging device are in the process of charging, the user can first take out the charging gun 21 with the replaced head, and then connect the charging gun 21 with the charging port of the vehicle, and then drive the pattern displayed on the display 18 to be a payment QR code through the QR code display unit 12, and then let the user scan the QR code, so that the user's mobile phone is connected to the Internet of Things 1, and then the Internet of Things 1 transmits the payment or unpaid data to the payment feedback unit 13. If the user does not pay, the payment feedback unit 13 can drive the QR code display unit 12 to run again. If the user completes the payment, the payment signal can be transmitted to the circuit control module 5 through the device startup unit 15, and the charging time can be counted through the timing unit 14;

[0083] During this process, when the circuit control module 5 receives the signal transmitted by the device start-up unit 15, it will drive the power transmitter 41 to transmit power to the handle 29, and then transmit power to the charging head 52 included in the charging head group 26 through the transmission pole 38, so that the charging head 52 can charge the vehicle.

[0084] During the above process, the opening of the liquid inlet tank allows the user to transfer the liquid to the heat dissipation cavity inside the charging box body 17, and then the liquid can cool the electronic control component 22 at the first equipment slot inside the charging box body 17. Then, the temperature detector 42 can be used to detect the liquid temperature inside the heat dissipation cavity. When the detection is completed, the data detected by the temperature detector 42 can be transmitted to the Internet of Things 1. When the liquid temperature is high, the maintenance staff can be prompted through network transmission, so that the staff can replace the liquid.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
