Description

Technical Field

[0001] This utility model relates to the field of anti-theft charging piles, specifically to an anti-theft charging pile. Background Technology

[0002] With the popularization of new energy vehicles, the charging pile industry is experiencing rapid growth. However, in actual operation, the theft of charging gun cables is frequent, causing serious economic losses to charging pile operators. Since the charging gun cable is a crucial component of the charging pile and must be exposed outside for user access, this provides an opportunity for criminals. As a high-value component of the charging pile, the theft of the charging gun cable not only causes direct economic losses but also affects the normal use of the charging pile and reduces the user experience.

[0003] Currently, most charging stations on the market lack effective anti-theft measures. Even those products that employ simple physical protection methods often fail to fundamentally solve the theft problem. When theft occurs, operators often struggle to detect it in time, making it impossible to stop the crime promptly. Furthermore, traditional anti-theft solutions suffer from slow response times and untimely alarms, failing to meet actual operational needs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an anti-theft charging pile, which solves the technical problems of slow response speed and untimely alarm in the existing anti-theft schemes for charging piles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides an anti-theft charging station, including a charging station, a control circuit board, a charging cable, a signal line, a charging gun, and an alarm. The control circuit board is equipped with a digital signal receiving module and a digital signal output module. The charging gun is electrically connected to the control circuit board via the charging cable. The signal line is located inside the charging cable, and both ends of the signal line are electrically connected to the digital signal receiving module. The alarm is electrically connected to the digital signal output module. When the signal line is disconnected, the digital signal output module switches the alarm from an open circuit state to a closed circuit state, and the alarm sounds.

[0006] In one possible implementation, the anti-theft charging station further includes a device management platform for transmitting data to the backend, the device management platform being electrically connected to the control circuit board.

[0007] In one possible implementation, the digital signal receiving module includes a DI input circuit, which has a DI1 port and a DI1_COM port, and the two ends of the signal line are electrically connected to the DI1 port and the DI1_COM port, respectively.

[0008] In one possible implementation, the anti-theft charging station further includes a power supply, and the digital signal output module includes a DO1 port, a DO1_COM port, and a relay, with both ends of the relay electrically connected to the DO1 port and the DO1_COM port, respectively. The alarm is electrically connected to the DO1 port, and the power supply is electrically connected to the DO1_COM port.

[0009] In one possible implementation, the charging cable is fitted with a protective sleeve.

[0010] In one possible implementation, the anti-theft charging station also includes a camera installed on the charging station.

[0011] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model uses a control circuit board as the core control unit, equipped with a digital signal receiving module and a digital signal output module. The signal line is located inside the charging cable, with both ends electrically connected to the digital signal receiving module, forming a closed-loop detection circuit. The alarm is electrically connected to the digital signal output module. The closed-loop connection between the signal line and the digital signal receiving module enables real-time monitoring of the charging cable status. The direct connection between the digital signal output module and the alarm ensures the rapid response capability of the anti-theft charging pile. Any act of damaging the charging cable will cause the signal line to disconnect and trigger the alarm mechanism, resulting in a faster response speed and timely alarm for the anti-theft charging pile. This solves the technical problems of slow response speed and untimely alarm in existing anti-theft charging pile solutions. Attached Figure Description

[0014] To solve the above-mentioned technical problems, the present invention provides a solution, and the technical solution and embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0016] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly, for example, they can refer to fixed connection, detachable connection, or integral connection; for those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0017] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0018] like Figure 1 As shown, this utility model provides an anti-theft charging station, including a charging station (not shown in the figure). The charging station is equipped with a control circuit board 1, a charging cable (not shown in the figure), a signal line 2, a charging gun 3, and an alarm 4. The control circuit board 1 is equipped with a digital signal receiving module 11 and a digital signal output module 12. The charging gun 3 is electrically connected to the control circuit board 1 via the charging cable. The signal line 2 is located inside the charging cable, and both ends of the signal line 2 are electrically connected to the digital signal receiving module 11. The alarm 4 is electrically connected to the digital signal output module 12. When the signal line 2 is disconnected, the digital signal output module 12 causes the alarm 4 to change from an open circuit state to a closed circuit state, and the alarm 4 sounds an alarm.

[0019] Among them, the control circuit board 1 refers to an electronic component that integrates signal processing and control functions. Specifically, it can be implemented using a microcontroller unit or a programmable logic device, and is used to receive the status information of the signal line 2 and control the working status of the alarm 4.

[0020] Charging cables are composite wire harnesses that carry both power and signal transmission. They can be implemented using a multi-core cable structure, which integrates power conductors and independent signal transmission lines.

[0021] Signal line 2 refers to a detection circuit conductor that is independent of the power transmission line. It can be implemented using low-voltage insulated wires, and its physical continuity serves as the basis for anti-theft detection.

[0022] The digital signal receiving module 11 is a detection unit used to monitor the on / off state of the circuit. Specifically, it can be implemented using a voltage comparator or an optocoupler isolation circuit to detect whether the two ends of the signal line 2 maintain electrical connection in real time.

[0023] The digital signal output module 12 refers to the drive unit that controls the on / off state of the alarm 4. Specifically, it can be implemented using a relay 121 switch or a transistor switch circuit, which switches the circuit state of the alarm 4 according to the detection result of the receiving module.

[0024] The alarm 4 open circuit state refers to the non-working circuit configuration when the device is in standby mode. Specifically, it can be implemented using a normally open contact relay 121 structure, which forms a closed circuit to trigger the audible and visual alarm only when the signal line 2 is disconnected.

[0025] The core innovation of this application lies in constructing a physical integration structure between the closed-loop detection system and the charging cable. By embedding an independent signal line 2 within the charging cable, a detection loop directly correlated with the cable's physical state is formed. When the cable is cut, the integrity of signal line 2 is simultaneously compromised, triggering a state switch for alarm 4. This design directly integrates the anti-theft detection function into the charging cable itself, achieving a direct correspondence between destructive behavior and alarm triggering, eliminating the need for additional detection devices.

[0026] The working process and principle of this application are as follows: the anti-theft charging pile includes a charging pile, a control circuit board 1, a charging cable, a signal line 2, a charging gun 3, and an alarm 4. The control circuit board 1, as the core control unit, is equipped with a digital signal receiving module 11 and a digital signal output module 12. The charging gun 3 is electrically connected to the control circuit board 1 via the charging cable to maintain normal charging function. The signal line 2 is located inside the charging cable, and both ends are electrically connected to the digital signal receiving module 11, forming a closed-loop detection circuit. The alarm 4 is electrically connected to the digital signal output module 12.

[0027] When the charging cable is intact, signal line 2 remains conductive, and the digital signal receiving module 11 continuously receives normal signals. At this time, the digital signal output module 12 keeps the alarm 4 in an open-circuit state and does not trigger the alarm.

[0028] If the charging cable is damaged, signal line 2 will disconnect. The digital signal receiving module 11 detects the signal interruption and immediately sends an abnormal command to the digital signal output module 12. Upon receiving the command, the digital signal output module 12 switches alarm 4 to the open state and triggers the alarm.

[0029] This design ensures that any damage to the charging cable will cause signal line 2 to disconnect, thereby triggering the alarm mechanism. Forming a closed loop between signal line 2 and the digital signal receiving module 11 enables real-time monitoring of the charging cable's status. The direct connection between the digital signal output module 12 and the alarm 4 ensures the system's rapid response capability.

[0030] In one possible implementation, the anti-theft charging station also includes a device management platform (not shown in the figure) for transmitting data to the backend, and the device management platform is electrically connected to the control circuit board 1.

[0031] The equipment management platform can employ an embedded computer system with data processing and communication capabilities. It establishes a communication connection with control circuit board 1 to receive burglar alarm signals generated by the board in real time. The platform converts the received alarm signals into standardized data formats, such as JSON or XML, and then transmits the data to a cloud-based backend server via 4G / 5G wireless networks or Ethernet. Upon receiving abnormal data, the backend server can trigger preset alarm rules and send real-time notifications to administrators via SMS, email, or mobile application push notifications.

[0032] The equipment management platform enables remote, real-time transmission of anti-theft status information, overcoming the physical space limitations of traditional local alarms. Managers can remotely and promptly obtain information on abnormal charging pile statuses, significantly improving response speed and efficiency, especially in unattended scenarios. Furthermore, by centralizing anti-theft information in the backend management system, unified monitoring and management of multiple charging piles can be achieved, enhancing overall operational efficiency.

[0033] See Figure 1 Specifically, the digital signal receiving module 11 includes a DI input circuit 111, which is provided with a DI1 port and a DI1_COM port. The two ends of the signal line 2 are electrically connected to the DI1 port and the DI1_COM port, respectively.

[0034] The DI input circuit 111 can employ optocoupler isolation technology to improve anti-interference capability. The DI1 port can be configured to be active high or active low to accommodate different signal types. The DI1_COM port, as a common terminal, can be connected to the system reference ground or the negative terminal of power supply 5. Signal line 2 can use a twisted-pair structure to reduce external electromagnetic interference. The DI input circuit 111 may also include a filter circuit to eliminate possible high-frequency noise, further improving the reliability of signal detection.

[0035] The configuration of ports DI1 and DI1_COM ensures that signal line 2 forms a closed loop, allowing for accurate detection of its continuity. This configuration improves the reliability and stability of signal detection, reducing false alarms or missed alarms caused by improper connections. Furthermore, the standardized port configuration facilitates maintenance and troubleshooting, enhancing the overall system performance and maintainability.

[0036] like Figure 1 As shown, specifically, the anti-theft charging station also includes a power supply 5, and a digital signal output module 12 including a DO1 port, a DO1_COM port, and a relay 121. The two ends of the relay 121 are electrically connected to the DO1 port and the DO1_COM port, respectively. The alarm is electrically connected to the DO1 port, and the power supply 5 is electrically connected to the DO1_COM port.

[0037] The relay 121 can be either an electromagnetic relay 121 or a solid-state relay 121. Its coil side is connected to the control circuit of the digital signal output module 12 via the DO1 port and the DO1_COM port, while its contact side is connected in series with the alarm 4 via the DO1 port to form an alarm circuit. The power supply 5 can be a DC power supply 5 or an AC power supply 5, with an output voltage range of 12V to 24V, directly powering the alarm circuit via the DO1_COM port. The rated current of the relay 121 contacts can be set to a range of 1A to 5A to meet the power requirements of different alarms 4. The connection between the DO1 port and the alarm 4 can be direct soldering or fixed via terminal blocks. The connection between the DO1_COM port and the power supply 5 can be configured with a fuse or overcurrent protection circuit.

[0038] Specifically, when signal line 2 is disconnected, the digital signal output module 12 outputs control signals to the DO1 and DO1_COM ports, driving the coil of relay 121 to engage and closing the contact-side circuit. At this time, power supply 5 supplies power to alarm 4 through the DO1_COM port, relay 121 contacts, and the DO1 port, triggering alarm 4 to sound an alarm. Because relay 121 provides electrical isolation between the control and alarm circuits, the digital signal output module 12 only needs to provide a low-power drive signal, while alarm 4 is directly powered by independent power supply 5, avoiding the risk of overload in the control circuit. Alarm 4 can obtain a stable operating voltage, and the contact opening and closing action is unaffected by control signal fluctuations. This design, through a dual mechanism of physical isolation and independent power supply, ensures that the alarm circuit has sufficient load-carrying capacity and anti-interference capability when triggered.

[0039] In one alternative embodiment, the charging cable is fitted with a protective sleeve (not shown in the figure).

[0040] The protective case can be made of flexible materials, such as rubber or plastic, with an inner tensile braided layer and an outer abrasion-resistant coating. It can be designed with sufficient thickness to provide adequate mechanical strength. The case can be segmented for easy installation and maintenance. The surface can have anti-slip textures to increase friction. It can be made of wear-resistant and corrosion-resistant materials to extend its service life.

[0041] The protective sleeve provides a physical layer of protection for the charging cable, reducing the risk of malicious cutting, pulling, or theft. The sleeve enhances the cable's mechanical strength, preventing false alarms caused by accidental disconnection of signal line 2 due to external force. Simultaneously, the sleeve slows down wear and corrosion caused by prolonged exposure. Furthermore, the sleeve makes tampering more difficult, objectively increasing the difficulty of theft and improving the overall reliability of the anti-theft solution.

[0042] In one alternative embodiment, the anti-theft charging station also includes a camera (not shown) installed on the charging station.

[0043] The camera can be installed on the top or side of the charging station, ensuring coverage of the area where the charging gun's three wires are located. The camera is electrically connected to control circuit board 1, which controls its operation. When signal line 2 is disconnected, control circuit board 1 not only triggers alarm 4 to sound an alarm but also simultaneously activates the camera to begin recording. The camera can be a high-definition digital camera with night vision capabilities to ensure clear recording of the scene under various lighting conditions. The camera's video data can be transmitted to the device management platform in real time or stored on a local storage device.

[0044] The installation of cameras upgrades the anti-theft functionality from passive alarms to active monitoring. The cameras not only record the theft process in real time, providing crucial video evidence for subsequent accountability, but also assist site administrators in quickly identifying the cause of the alarm through visual information. Furthermore, the presence of the cameras themselves has a deterrent effect, effectively reducing the probability of theft. This combination of video surveillance and alarm systems significantly improves the security and management efficiency of anti-theft charging stations.

[0045] The above description is merely a preferred embodiment of the present utility model, and the specific embodiments described above are not intended to limit the present utility model. Various modifications and variations can be made within the scope of the technical concept of the present utility model. All refinements, modifications, or equivalent substitutions made by those skilled in the art based on the above description are within the scope of protection of the present utility model.
