[0034] S44, if the box cannot be lifted, it is initially determined that the lifting mechanism is faulty, the locking state of the lifting mechanism and the shell can be released by the anti-theft lock on the first layer of the box, and the box together with the lifting mechanism can be pulled out of the ground by external force to inspect and maintain the lifting mechanism;

[0035] S45. After the inspection and maintenance are completed, the box and the lifting mechanism are returned to their original positions, and the anti-theft pin is locked. The operation and maintenance personnel change the display of the LED display screen from fault inspection to equipment idle through the APP.

[0036] The beneficial effects of the present invention are as follows:

[0037] 1. Based on the existing underground charging piles and relying on the existing road surface structure, the present invention proposes a semi-underground hidden charging pile structure design, which is convenient for placing the present invention on both sides of the road.

[0056] The box 1 and the shell 2 are mainly made of SMC composite materials, which have the characteristics of high strength, high hardness, corrosion resistance, heat resistance, and excellent insulation. The first layer of transparent cover is made of tempered glass, which can be transparent in terms of permeability, so as to facilitate the display of information on the LED display screen 9. The shell 2 is pre-buried in the ground, and the outside is directly cast with the underground concrete. The appearance of the box 1 is consistent with the curbstone, standing at the junction of the road and the sidewalk, and part of the body is above the road surface, playing the role of the curbstone. The top of the box 1 remains in a transparent state of tempered glass, and the other sides are sprayed with stone paint to imitate the curbstone.

[0057] The box 1 is mainly divided into three layers. The first layer has a built-in LED display screen 9 and a control terminal 3. The specific information displayed on the LED screen inside the box 1 can be seen through the top of the box 1. The second layer is used to store the charging gun 4 and fix the charging cable. A movable slot cover is opened on the side of the box 1 facing the road, and the charging gun 4 can be taken out by opening the first slot cover. The third layer is used to place the charging cable winding device 5 and the charging pile body 6.

[0058] A lifting mechanism 7 for lifting the box 1 is provided at the bottom of the housing 2, and a line channel for supplying power to the box 1 and the lifting mechanism 7 is reserved on the side of the box 1. The first, second and third layers of the box 1 are all provided with threading holes 11;

[0059] The lifting mechanism 7 can be a hydraulic lift, and the line channel is used for the charging line of the charging gun 4, the power supply and control circuit of the control terminal 3 and the hydraulic mechanism to pass through. At the same time, wire holes 11 are provided on each layer of the box body 1 to achieve communication with the line channel.

[0060] The bottom of the box body 1 is connected to the upper end of the lifting mechanism 7. After the facility is started, the second and third layers of the box body 1 can be lifted above the road surface in layers as needed, so as to achieve the purpose of normal use or operation and maintenance.

[0061] The anti-theft pin 14 has one end connected to the anti-theft lock 13 and the other end passing through the box body 1 and hooking the bottom of the shell 2 .

[0062] The bottom of the lifting mechanism 7 is provided with an anti-theft mechanism in the form of a lock pin, which is tightly fixed to the bottom of the housing 2 by the lock pin during normal operation. The first layer of the box body 1 is provided with an anti-theft lock 13, which is rotated by inserting a special key to drive the lock pin arm to rotate axially and then control the opening and closing of the anti-theft pin 14, so as to achieve the locking or unlocking of the bottom of the lifting mechanism 7 and the housing 2, thereby achieving the anti-theft purpose of preventing the box body 1 from being pulled out by external force, and the box body 1 can be pulled out together with the lifting mechanism 7 when the lifting mechanism 7 is inspected.

[0063] As an example, the first slot cover and the second layer are internally installed with a slide rail capable of lifting the first slot cover upward to a horizontal plane and retracting it into the second layer;

[0064] Slide rails are installed inside the second slot cover and the third layer, which can enable the second slot cover to be lifted up to a horizontal plane and retracted into the third layer.

[0065] As an example, the charging cable winding device 5 is an elastic cable reel.

[0066] The charging cable winding device 5 can be an elastic cable reel, the outlet end is connected to the charging gun 4, and the inlet end is connected to the charging pile body 6. The charging cable winding device 5 can tighten the spiral spring to store energy when the charging cable is pulled out, and release the energy when the external force is removed, thereby automatically winding up the charging cable, thereby achieving the purpose of automatically storing the charging cable. The winding device is automatically locked when a certain length is pulled out. The locking gear is the second gear, which can be 1.5 meters or 3 meters. After locking, after applying tension again, it can be unlocked and restored to the elastic retracted state.

[0067] As an example, the first slot cover and the second slot cover both have sealing strips on their inner sides, which can seal the box body 1 when not opened to prevent water and moisture, and other sealing measures may also be used.

[0068] As an example, drainage grooves are provided at the top and bottom of the second and third layers, and one-way check valves are provided in the drainage grooves. The drainage grooves are connected to the drainage holes 12 at the bottom of the shell 2, and the drainage holes 12 are connected to the underground drainage pipes.

[0069] As an example, the contact surface between the box body 1 and the shell 2 adopts a smooth waterproof bushing.

[0070] The LED display screen 9, control terminal 3, charging gun 4, charging cable and lifting mechanism 7 and other equipment all have IP68 level waterproof function.

[0071] As an example, a smooth bushing is provided in the threading hole 11, and arc surface transition structures are provided at both ends of the smooth bushing to prevent scratching of the line.

[0072] As an example, the first access control 8 and the second access control 15 are electromagnetic locks. The second and third slot covers of the box body 1 are provided with access control circuits of electromagnetic locks, which are connected to the circuits of the top-level control terminal 3 and are provided with a card swiping sensing area, which can be electrically unlocked and manually opened by the first-level control terminal 3 or external card swiping.

[0073] As an example, the first slot cover is provided with a card swiping sensing device for opening the first slot cover and the second slot cover by swiping a maintenance card.

[0074] It is convenient for maintenance personnel to repair and maintain the facilities.

[0075] As an example, Figure 4 As shown, a charging APP is also included, and the charging APP interacts with the control terminal 3, and the LED display screen 9 is provided with a charging QR code.

[0076] The control terminal 3 plays an important role in the charging facility. Its main functions include outputting necessary information to the LED display screen 9, obtaining necessary charging information of the charging pile body 6, opening the access control system of the first slot cover and the second slot cover, and controlling the action of the lifting mechanism 7. The control terminal 3 is powered by the power supply line and supports external power supply. It is equipped with a SIM card inside, and can realize data interconnection and intercommunication with the data background of the charging pile body 6 system. In addition, the control terminal 3 includes an emergency power supply, which can still operate after a sudden power failure, output fault information to the background as soon as possible, and provide necessary power for operation and maintenance. The LED display screen 9 is connected to the control terminal 3 and can scroll to display the facility startup QR code and related charging information. The charging facility status information mainly includes words such as equipment idle, charging, charging end or fault maintenance, and can also display information such as the charged power, current current voltage, and estimated remaining time to be fully charged according to needs. The input end of the charging pile body 6 is connected to the power supply, and the default input is an AC 220V power supply. The output end of the charging pile body 6 is connected to the charging gun 4 through the charging line winding device 5. The charging gun 4 is provided with an induction circuit for detecting the connection status between the charging gun 4 and the electric vehicle, and can feed back charging status information to the charging pile body 6 after the electric vehicle is connected.

[0077] like Figure 7 As shown, in normal use, there are three steps: charging connection, charging start, and charging end:

[0078] 1. Charging connection

[0079] 1. When the charging facility LED display screen 9 shows that it is idle, the user can start charging in two ways. One is to scan the QR code displayed on the LED display screen 9 through the mobile phone charging APP software and select to confirm the charging operation. After selecting to confirm, the mobile phone APP software transmits the confirmation information to the data background, and the data background transmits the information to the control terminal 3 of the parking space corresponding to the QR code. The second is to use the municipal government's road parking fee APP, enter the license plate number, and the APP will locate the parking space, and transmit the information to the data background, which will then locate the control terminal 3 of the parking space. Both methods can initiate a wireless signal to start charging to the control terminal 3.

[0080] 2. After receiving the start signal from the data background, the control terminal 3 controls the lifting mechanism 7 to completely lift the box 1 to the ground, and releases the electronic access control of the second floor, which is the floor where the charging gun 4 is located. The user opens the first slot cover, pushes the first slot cover into the box 1, and takes out the charging gun 4.

[0081] 3. The user holds the charging gun 4 and pulls the charging cable. The charging cable is pulled out by the charging cable winding device 5 and automatically locked after being pulled out to a suitable length. The user inserts the charging gun 4 into the charging port of the electric vehicle to complete the charging connection. At this time, turn off the power of the electric vehicle, and the charging port of the electric vehicle will lock the charging gun 4 to ensure that the charging connection will not be accidentally disconnected and prevent the charging gun 4 from being pulled out by others.

[0082] 2. Start the charging process

[0083] 1. The charging pile body determines whether the charging gun 4 is connected to the electric vehicle through the connection induction circuit. If the connection is successful, the charging pile body 6 outputs the charging current and starts charging the electric vehicle.

[0084] 2. After charging is started, the LED display screen 9 changes from idle to charging, and the charging pile body 6 starts timing and charging, and monitors the charging status of the electric vehicle in real time. During the charging process, the relevant information output by the charging pile body 6 is synchronized to the data background in real time through the control terminal 3, and then synchronized to the user's mobile phone APP by the data background.

[0085] 3. During the charging process, if the user wants to end the charging, he can choose to end the charging on the mobile phone APP. After the data background obtains the APP charging end information, it sends a stop charging signal to the control terminal 3, thereby ending the charging state of the charging pile body 6, and the charging pile body 6 stops delivering the charging current. The user can also turn on the power of the electric vehicle, unlock the charging port and the charging gun 4, and remove the charging gun 4 to end the charging process. After performing the above operations, the LED display screen 9 changes from charging to charging end.

[0086] 3. Charging End

[0087] 1. When the battery is fully charged, the charging pile body 6 automatically stops delivering charging current and starts fee settlement through real-time monitoring. The fee bill will be pushed to the user's mobile phone APP at the same time, and the LED display screen 9 will change from charging to charging completed.

[0088] 2. After turning on the power of the electric vehicle, the user can remove the charging gun 4 and put it back into the box 1, and then manually close the first slot cover. In the process of putting back the charging gun 4, the charging cable winding device 5 will automatically tighten the charging cable. After the first slot cover is completely closed, the access control circuit is connected and the first slot cover is automatically locked. After the control terminal 3 recognizes that the first slot cover is closed, it starts the lifting mechanism 7 and returns the box 1 as a whole to its original position. The LED display screen 9 changes from charging completed to idle.

[0089] 3. If the charging pile body 6 detects that the connection between the electric vehicle and the charging gun 4 is accidentally disconnected during charging, the current output will be automatically stopped and the fee settlement will begin. After the fee is settled and the order is paid, the user can charge next time, otherwise the APP will always prompt the order payment request and charging cannot be started again.

[0090] In addition, if Figure 8 The present invention also proposes equipment maintenance links:

[0091] 4. Equipment maintenance

[0092] 1. When the user finds that the charging facility cannot be charged at any stage, he can upload the fault information reporting function to the data background through the mobile phone APP. The data background will send the information back to the control terminal 3, the LED display screen 9 will display the fault maintenance status, and stop providing charging services.

[0093] 2. After the equipment operation and maintenance personnel query the equipment fault information through the data background, they can quickly locate the control terminal 3 where the fault is reported and perform on-site inspection and maintenance.

[0094] 3. Equipment operation and maintenance personnel can obtain control authority of control terminal 3 through the QR code on LED display screen 9 and fully raise the box 1. After raising, they can use a special maintenance card with NFC function to open the slot covers of the second and third layers of box 1 respectively through the card sensor on the slot cover, or remotely control terminal 3 to open the slot cover to inspect and maintain different equipment in the facility. If the emergency power supply of control terminal 3 is also completely lost, the first slot cover of box 1 can be opened with a key to provide external power for control terminal 3.

[0095] 4. If the box 1 cannot be lifted and it is initially determined that the lifting mechanism 7 is faulty, the locking state between the lifting mechanism 7 and the housing 2 can be released through the anti-theft lock 13 of the first layer of the box 1. The box 1 together with the lifting mechanism 7 can be pulled out of the ground by external force. After being pulled out as a whole, the operation and maintenance personnel can directly inspect and maintain the lifting mechanism 7.

[0096] 5. After the inspection and maintenance is completed, the charging facility is returned to its original position through the control terminal 3. If the box 1 and the lifting mechanism 7 have been pulled out as a whole, it is necessary to manually put the whole device back to its original position and lock the anti-theft pin 14. At this time, the operation and maintenance personnel can change the LED display screen 9 from fault inspection to equipment idle through the APP.

[0097] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
