[0019] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0020] Example 1, as Figures 1 to 3 As shown, an integrated electronic lock for a new energy charging pile with a locking function includes a hollow shell 1, a driving motor 2 is fixedly installed in the hollow cavity of the shell 1, a gear 3 is fixedly sleeved on the driving shaft of the driving motor 2, a lock hole is opened on the lower surface of the shell 1, a latch 4 is installed in the hollow cavity of the shell 1, the lower end of the latch 4 moves through the lock hole, a rack 5 is vertically provided on one side of the upper end of the latch 4, the rack 5 is engaged with the gear 3, a positioning block 6 is provided on the other side of the upper end of the latch 4, and the positioning block 6 slides vertically up and down in the hollow cavity of the shell 1; the power terminal of the driving motor 2 is connected to the PCB board 16, and the PCB board 16 is connected to the external controller through the control line 7.

[0021] Working principle:

[0022] During use, the external controller performs signal judgment and triggers the electronic lock to operate when the charging gun is inserted (the external controller and its control logic adopt existing technology and will not be described in detail). At this time, the external controller applies a DC voltage of 12V and outputs it to the PCB board 16 through the control line 7. The drive motor 2 is then energized through the PCB board 16. After receiving the current signal, the drive motor 2 drives the gear 3 to rotate through the drive shaft. The gear 3 engages with the rack 5, which drives the latch 4 downward to pass through the lock hole, thereby locking the charging gun and preventing it from being pulled out during operation. This effectively prevents the theft and misuse of the charging gun, improving the safety of the charging facility and the user experience.

[0023] When charging is complete, the external controller applies a reverse DC voltage to control the drive shaft of the drive motor 2 to reverse, which in turn drives the rack 5 upward through the gear 3, causing the entire latch 4 to retract upward into the hollow cavity of the housing 1, completing the unlocking action.

[0024] In Example 2, a further preferred embodiment of Example 1, a microswitch 8 is installed within the hollow cavity of the housing 1, and a sensing protrusion is provided on the side of the positioning block 6. The switch reed of the microswitch 8 flexibly cooperates with the sensing protrusion. The signal output terminal of the microswitch 8 is connected to an external controller via a wire 9. When the drive shaft of the drive motor 2 rotates the gear 3, the latch 4 moves downward. When it moves to a certain position, the sensing protrusion on the side of the positioning block 6 presses against the switch reed of the microswitch 8, triggering the microswitch 8. The microswitch 8 then transmits a signal to the external controller via the wire 9, which then controls the drive motor 2 to stop, thereby locking the charging gun.

[0025] Embodiment 3, as a further preferred embodiment of embodiment 1, further comprises a handle 10. A handle mounting hole 11 is provided on the front side of the housing 1. The driving end of the handle 10 passes through the handle mounting hole 11 and is coaxially fixedly connected to the front end of the gear 3. Thus, in the event of a power outage, the handle 10 can be manually rotated to drive the gear 3 to rotate via the driving end of the handle 10, thereby achieving manual locking or unlocking.

[0026] Embodiment 4, as a further preferred embodiment of embodiment 1, a rubber ring 12 is fixedly installed between the driving end of the handle 10 and the front end of the gear 3. The rubber ring 12 is used to ensure the stability of the connection between the driving end of the handle 10 and the gear 3.

[0027] In the fifth embodiment, as a further preferred embodiment of the first embodiment, a positioning shaft 13 is vertically fixedly mounted within the hollow cavity of the housing 1. A through hole 14 extending vertically therethrough is defined in the center of the positioning block 6. The positioning block 6 is movably sleeved onto the outer surface of the positioning shaft 13 through the through hole 14. The positioning shaft 13 allows the positioning block 6 to move vertically along the axial direction of the positioning shaft 13, thereby providing a guiding and limiting effect on the positioning block 6 and preventing the positioning block 6 from deflecting during movement.

[0028] Example 6, as a further preferred embodiment of Example 1, comprises a lower housing 101 and an upper cover 102. The upper cover 102 is fixedly mounted above the lower housing 101. A flat rubber washer 15 is fixedly mounted on the lower surface of the lower housing 101. Therefore, during repair and maintenance, the components within the hollow cavity of the housing 1 can be accessed simply by opening the upper cover 102. The installation of the flat rubber washer 15 on the lower surface of the lower housing 101 improves the anti-slip and wear resistance of the housing 1.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
