Abstract
Description
Technical Field
[0001] This utility model belongs to the field of charging pile anti-theft. Specifically, this utility model relates to a charging pile anti-theft device and a charging pile. Background Technology
[0002] Currently, private AC charging stations are being deployed in high density in underground parking garages of residential communities. Due to the lack of identity authentication and control mechanisms, charging interfaces can draw power without authorization, leading to frequent cases of unauthorized vehicles charging without permission, resulting in electricity bill losses for residents and potential safety hazards.
[0003] For example, publication number CN118971304A, publication date 2024-11-15, entitled "Charging Pile Circuit and Home Charging Pile," discloses a charging pile circuit and a home charging pile, relating to the field of charging pile technology. The charging pile circuit includes a relay circuit, a power supply circuit, an emergency stop circuit, a CP signal generation and detection circuit, and a control circuit. The relay circuit controls the connection / disconnection of external AC power. When external AC power is connected, the power supply circuit converts the external AC power into a charging power output, allowing the charging device to charge. The CP signal generation and detection circuit generates a stable CP signal for communication with the charging device. The emergency stop circuit disconnects the power supply circuit from the external AC power in case of a charging failure, ensuring charging safety. However, the aforementioned publication lacks anti-theft measures.
[0004] Therefore, this application proposes an anti-theft device for charging piles and a charging pile. Utility Model Content
[0005] This utility model aims to overcome the shortcomings of the prior art and proposes a charging pile anti-theft device and a charging pile to achieve the following purpose: to realize the anti-theft of charging piles.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a charging pile anti-theft device, the device comprising a charging gun S3 switch, a retractable pad, an actuator, a controller, and an identification module, wherein the top of the retractable pad abuts against the charging gun S3 switch; the actuator is connected to the retractable pad and is used to drive the retractable pad to extend or retract according to the control signal of the controller; the controller is connected to both the identification module and the actuator and is used to send a control signal to the actuator according to the information from the identification module.
[0007] Preferably, a rubber pad is installed on the top of the retractable pad.
[0008] Preferably, the device further includes a timer connected to the controller.
[0009] Preferably, the device further includes an alarm device, which is connected to the controller.
[0010] Preferably, the identity recognition module includes a fingerprint recognition device, a password lock, and a facial recognition device.
[0011] Preferably, the controller includes a microcontroller (MCU).
[0012] This application also proposes a charging pile, which includes the above-mentioned anti-theft device for the charging pile.
[0013] The technical advantages of this invention are as follows: The retractable pad of this invention physically restricts the charging of the charging station, making it safer and more reliable. Simultaneously, in conjunction with the identity recognition module, the restriction of the corresponding S3 switch on the retractable pad is only released when identity verification is successful, allowing normal charging and thus achieving anti-theft protection for the charging station.

[0015] Figure 2 A circuit diagram for AC charging control guidance of existing charging piles. Detailed Implementation
[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The purpose is to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation. It should be noted that the terms "first," "second," etc., used in this application are only for the convenience of describing the technical solution and distinguishing different components, and are not intended to limit this application. To make the technical solution of this utility model clearer, it will be explained and illustrated through the following embodiments.
[0017] This embodiment provides a charging pile anti-theft device, such as Figure 1 As shown, the device includes a charging gun S3 switch, a retractable pad, an actuator, a controller, and an identification module. The top of the retractable pad abuts against the charging gun S3 switch. The actuator is connected to the retractable pad and is used to drive the retractable pad to extend or retract according to the control signal from the controller. The controller is connected to both the identification module and the actuator and is used to send control signals to the actuator according to the information from the identification module.
[0018] The S3 switch on the charging gun is an internal switch for standard AC charging guns. Figure 2As shown, under normal circumstances, the switching process of the charging gun's S3 switch during charging is: closed-open-closed. That is, when the charging gun is not inserted, S3 is in the closed state by default; when the charging gun is first inserted, S3 is pushed open; as the charging gun continues to be inserted, S3 springs back to the closed state.
[0019] Therefore, to prevent theft, this embodiment incorporates a retractable pad against the S3 switch of the charging gun. The retractable pad is in its highest position by default, ensuring that the S3 switch will not disconnect, thus preventing normal charging. The extension and retraction of the retractable pad is achieved by an actuator driven by the controller. An identification module is connected to the controller; only when identification is successful will the controller lower the height of the retractable pad via the actuator, thereby releasing the restriction on the S3 switch, allowing normal charging to proceed.
[0020] In this embodiment, the retractable pad includes a pad and a base with a through hole. The pad can be inserted into the base through the through hole. The corresponding actuation mechanism is an electric push rod, the top of which is connected to the bottom of the pad. The movement of the electric push rod can cause the pad to extend or retract relative to the base. In specific implementations, the retractable pad and the corresponding actuation mechanism can be flexibly selected according to the actual situation.
[0021] In addition, this embodiment also has a rubber pad installed on the top of the retractable pad to prevent damage caused by direct collision and friction between the top of the retractable pad and the charging gun S3 switch.
[0022] In this embodiment, the controller uses a microcontroller (MCU), which has the advantages of small size and easy deployment, reducing the application cost of the device in this embodiment. The identity recognition module is connected to the controller and is used to verify the user's identity and send the verification result to the controller. The identity recognition module includes a fingerprint recognition device, a password lock, a face recognition device, etc., and can be flexibly selected according to the actual situation in specific implementation.
[0023] The device in this embodiment also includes an alarm device connected to the controller. The alarm device is used by the controller to alert the user when it receives authentication failure information. The alarm device includes a local alarm device and a remote alarm device. The local alarm device includes a buzzer, an alarm light, etc., all connected to the controller, and alarms are triggered at the charging station location to remind unauthorized users. The remote alarm device includes a remote communication device connected to the controller. The controller communicates wirelessly with the user's mobile device through the remote communication device to alert the user.
[0024] The device in this embodiment also includes a timer connected to the controller. After identity verification triggers the retractable pad to lower its height, the controller needs to reset the retractable pad to ensure the next anti-theft operation. Simultaneously, to ensure normal charging, the S3 switch needs to remain in the off state for a period of time. Therefore, this embodiment includes a timer. After identity verification triggers the retractable pad to lower its height, the controller starts the timer. The timer has a preset timeout period. After the timeout period ends, the timer sends a timeout end signal to the controller, which then controls the retractable pad to reset upon receiving the signal.
[0025] This embodiment also proposes a charging pile, which includes the above-mentioned anti-theft device for charging piles.
[0026] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
