[0002] Issues such as charging station construction and charging safety are key factors influencing the development of electric vehicles. To ensure the safety of people, vehicles, and charging stations during charging, charging guns must have certain protective features to prevent accidental disconnection when plugged in and automatically unlock after charging is complete. Utility Model Content

[0003] The purpose of the utility model is to provide an electronic lock for a vehicle-end charging socket, so as to solve the problem that the mechanical structure of the electronic lock in the prior art is relatively complex and the charging gun cannot be safely pulled out in an emergency.

[0004] In order to solve the above problems, the electronic lock of the vehicle-side charging socket involved in this utility model adopts the following technical solutions:

[0005] An electronic lock for a vehicle-side charging socket, comprising:

[0006] The electronic lock housing includes an electronic lock face cover and an electronic lock bottom cover, and the electronic lock face cover and the electronic lock bottom cover are fixed by fasteners;

[0007] A push rod is a locking actuator for the electronic lock of the vehicle-side charging socket;

[0008] The electronic lock module is installed in the electronic lock housing and is used to drive the push rod to perform reciprocating linear motion; and it includes a drive motor, a driven gear and a screw rod. The output end of the drive motor is provided with a drive gear, the drive gear is connected to the driven gear in a reduction transmission, and the screw rod is concentrically connected to the push rod;

[0009] A manual unlocking module includes an unlocking rod and a pull rope. The bottom cover of the electronic lock is provided with a strip-shaped slide groove, and the unlocking rod is slidably arranged in the strip-shaped slide groove;

[0010] When the electronic lock module drives the push rod to move, the push rod drives the unlocking rod to slide in the strip-shaped sliding groove;

[0011] The screw rod includes a screw rod and a connecting block. The electronic lock bottom cover is provided with a mounting column located at the front end of the screw rod. The mounting column is provided with a fixing groove. A bearing is installed in the fixing groove. The front end of the screw rod is rotatably connected to the bearing.

[0012] Preferably, the manual unlocking module further includes a compression spring, the elastic force direction of the compression spring is consistent with the extension direction of the push rod, one end of the compression spring is connected to the unlocking rod, and the other end is connected to the bottom cover of the electronic lock.

[0013] Preferably, a card slot is provided on the end of the unlocking rod away from the spring, and a buckle is provided at one end of the pull rope that is engaged with the card slot. A mounting slot is provided on one side of the bottom cover of the electronic lock, and the bottom cover of the electronic lock is detachably connected to a mounting seat through the mounting slot. An inner cavity for accommodating the connecting part of the pull rope and the unlocking rod is formed in the mounting seat, and the mounting seat is connected to a cover body, and the cover body and the mounting seat cooperate to form a channel that facilitates the extension and retraction of the pull rope.

[0014] Preferably, the screw rod and the driven gear are designed as an integral unit, and the screw rod is fixed on the center hole of the driven gear.

[0015] Preferably, a connector, a PCBA and two tact switches located on one side of the connecting block are provided in the electronic lock housing, and grooves corresponding to the two tact switches are provided at both ends of one side of the connecting block. When the connecting block slides back and forth, the two tact switches will be triggered respectively. The connector and the two tact switches are electrically connected to the PCBA, and a socket for accommodating the connector is formed on one side of the electronic lock housing. The connector is a cable or a pin header, and the pin header is matched with a connecting socket, and the cable is matched with a silicone part. The shapes of the connecting socket and the silicone part are matched with the socket, and a solder pad with a hole is provided on the PCBA, and the cable and the pin header are connected to the PCBA through the solder pad with a hole.

[0016] Preferably, a hook is provided on the unlocking rod, and a slot for engaging with the hook is formed on one side of the connecting block.

[0017] Preferably, the electronic lock module and the manual unlocking module are accommodated in the electronic lock housing, and the push rod can be extended and retracted relative to the housing.

[0018] Preferably, the pull rope is connected to the unlocking rod and extends from the electronic lock housing.

[0019] Preferably, the two tact switches are respectively a locking switch contact and an unlocking switch contact; when the electronic lock module drives the connecting block to abut against the locking switch contact or the unlocking switch contact, the PCBA controls the electronic lock module to stop working.

[0020] The present utility model also provides a charging gun, which is based on the aforementioned vehicle-end charging socket electronic lock and includes a charging gun body, a charging gun face cover and a charging gun lock hook. A cavity for accommodating the vehicle-end charging socket electronic lock is formed in the charging gun body. The middle part of the charging gun lock hook is connected to the charging gun body for limited rotation. The unlocking button abuts against the lower end of the rear side of the charging gun lock hook. The charging gun face cover is used to close the cavity of the charging gun body. The charging gun face cover is provided with a button abutting against the upper end of the rear side of the charging gun lock hook.

[0021] The beneficial effects of this utility model are as follows: When the PCBA receives a lock or unlock command, it sends a signal to the electronic lock module, which activates the motor. The motor's operation rotates the driven gear, thereby initiating the entire locking or unlocking process. The rotation of the driven gear rotates the lead screw. The lead screw is threadedly connected to the connecting block, and the rotation of the lead screw converts this rotational motion into linear motion of the connecting block. This linear motion of the connecting block directly drives the push rod, causing it to extend or retract.

[0022] When the connecting block moves in the bar-shaped slide, it drives the unlocking lever shaft to slide synchronously. This movement ensures the synchronization of locking and unlocking operations through linkage with the push rod, so that the unlocking lever shaft maintains the correct relative position during the locking and unlocking process. When the push rod moves to the specified locked or unlocked position, the groove on the connecting block triggers the lock switch contacts or unlock switch contacts respectively. The trigger signals of these tactile switches are transmitted to the controller through the PCBA (printed circuit board assembly), and the controller determines whether the operation is complete based on the signal. Once the PCBA receives the signal from the tactile switch and confirms that the push rod has reached the final locked or unlocked position, it will immediately send a signal to stop the drive motor and prevent the push rod from moving further, thereby protecting the various components of the system and saving energy.

[0023] When the electronic lock module fails or needs to be unlocked urgently, the user can manually unlock it by pulling the rope. When the user pulls the rope, the rope drives the unlocking rod 41 to move backward, and then drives the connecting block to slide backward. This manual operation can release the locking state of the push rod and realize manual unlocking of the charging pile. During manual unlocking or retraction of the push rod, the elastic member (compression spring) plays a role to help the push rod reset. The elastic member provides the necessary elastic force to ensure that the unlocking rod and the push rod can smoothly return to their initial position, ensuring the stability of the system after manual operation.

[0024] The electronic lock module is the core driving component of this utility model. An electric motor drives the lead screw-nut structure to achieve linear motion of the push rod. This drive allows the push rod to precisely extend and retract, completing the locking and unlocking functions. This automated control method not only simplifies the user's operation process but also improves the system's responsiveness, making it particularly suitable for applications requiring rapid locking and unlocking, such as public charging stations. To ensure the reliability and accuracy of locking and unlocking, the system features two tactile switches at either end of the push rod's travel. When the push rod reaches the locked or unlocked position, the corresponding tactile switch is triggered, providing feedback to the PCBA (printed circuit board assembly). Upon receiving this signal, the PCBA immediately stops the electronic lock module, preventing further movement of the push rod and avoiding issues like over-tightening or incomplete locking. This feedback mechanism significantly improves the lock's control precision, ensuring the accuracy and safety of each locking and unlocking operation. In the event of electronic system failure or anomaly, the system provides a manual unlocking module as a backup. This module, with its pull cord and unlocking lever, allows the user to quickly manually release the lock in an emergency. The close coordination of the pull cord and the release lever ensures reliable operation, allowing users to quickly unlock the device even in the event of a power failure. This improves the system's emergency response capabilities and enhances the safety of the charging station. Both the electronic lock module and the manual release module are independently encapsulated within the electronic lock housing. This modular design effectively protects the electronic and mechanical components within each module from environmental influences, extending the system's service life. The modular structure also facilitates maintenance and replacement. Maintenance personnel only need to remove and replace individual modules when necessary, without having to dismantle the entire lock, significantly improving maintenance efficiency and reducing repair costs. The mechanical transmission system utilizes a screw-nut structure. Compared to complex gear or belt drives, this structure is simpler and more reliable, providing stable transmission performance within limited space. The rotation of the screw enables the push rod to precisely move in a straight line, enabling efficient locking and unlocking operations. Furthermore, this structure offers a high load capacity and a long service life, reducing the failure rate of the transmission system and significantly improving the overall reliability of the system. The overall design of this utility model is very compact, integrating the electronic lock module, push rod, guide rail, and manual release components into a single housing. This compact design is ideal for installation in space-constrained equipment such as charging stations, and is particularly advantageous when deployed in urban public facilities or confined spaces. The modules fit tightly together within the housing, reducing wasted space and minimizing system size while maintaining system stability. Through feedback from a touch switch, the electronic lock module operates only when necessary. When the push rod reaches the designated locked or unlocked position, a feedback switch immediately signals the controller to stop the motor.This precise control based on real-time feedback greatly reduces unnecessary energy consumption and avoids the situation where the motor runs for a long time or idles, thereby achieving the energy-saving effect of the system and extending the battery or power supply life. It is particularly suitable for frequently used charging pile scenarios. Due to the modular design, the charging pile electronic lock of the present invention is very simple in production and installation. Each module can be assembled and tested independently, reducing the complex processes in the production process. At the same time, the modular design also makes the system highly scalable and can flexibly adjust the configuration according to the needs of different charging piles, thereby meeting the usage requirements of different scenarios. The charging pile electronic lock of the utility model realizes efficient, stable and intelligent locking and unlocking functions through technologies such as automatic drive, manual emergency unlocking, modular packaging and screw-nut transmission. It has a simple and compact structure and is easy to install. It is suitable for large-scale application in public charging pile scenarios, and at the same time has high reliability, durability and energy saving. This design not only improves the user's convenience, but also provides an effective solution for the management and maintenance of charging piles. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the technical objectives, technical solutions, and beneficial effects of the present invention more clear, the technical solutions of the present invention are further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0037] The electronic lock of the vehicle-side charging socket of the preferred embodiment of the utility model is as follows Figure 1 As shown, see Figure 2-8 ,include:

[0038] The electronic lock housing 1 includes a front cover 11 and a bottom cover 12, which are secured together by fasteners, forming a closed structure that protects the internal components from external influences. This housing structure not only provides protection but also supports the mounting rails and guide slots.

[0039] Push rod 2 is the locking actuator for the vehicle-side charging socket's electronic lock. Its reciprocating linear motion is controlled by the electronic lock module. Extending the push rod locks the vehicle, while retracting it unlocks the vehicle.

[0040] The electronic lock module 3 is installed in the electronic lock housing 1 and is used to drive the push rod 2 to perform reciprocating linear motion; and it includes a drive motor 31, a driven gear 32 and a screw rod 33. A drive gear 34 is provided on the output end of the drive motor 31. The drive gear 34 is connected to the driven gear 32 through a reduction transmission, and the screw rod 33 is concentrically connected to the push rod 2 through a transmission; the electronic lock module is responsible for driving the push rod and can realize automatic locking and unlocking actions.

[0041] The manual unlocking module 4 includes an unlocking lever 41 and a pull cord 42. The unlocking lever 41 slides within a bar-shaped slot 43 provided on the electronic lock bottom cover 12. The unlocking lever is mounted on the electronic lock bottom cover and slides through the bar-shaped slot to manually unlock the lock. When the electronic lock module drives the push rod, the push rod slides within the bar-shaped slot via the first connecting shaft unlocking lever 41.

[0042] When the electronic lock module 3 drives the push rod 2 to move, the push rod 2 drives the unlocking rod 41 to slide in the strip-shaped sliding groove 43 .

[0043] The screw rod 33 includes a screw rod 331 and a connecting block 332. The electronic lock bottom cover 12 is provided with a mounting post 121 located at the front end of the screw rod 331. The mounting post 121 is provided with a fixing slot 122. A bearing 123 is installed in the fixing slot 122. The front end of the screw rod 331 is rotatably connected to the bearing 123. The front end of the screw rod is fixed to the mounting post on the electronic lock bottom cover by a bearing, ensuring smooth rotation of the screw rod during operation, avoiding shaking or offset problems caused by an unstable front end of the screw rod, and improving the transmission stability and accuracy of the entire electronic lock system. By installing a bearing in the fixing slot, the friction of the screw rod during rotation can be effectively reduced, reducing wear on mechanical components, extending the service life of the screw rod, and thus improving the durability and reliability of the system. The use of the bearing reduces the resistance of the screw rod during rotation, making the movement between the screw rod and the connecting block smoother, thereby improving the overall transmission efficiency of the electronic lock module and ensuring the rapid response of the push rod during locking and unlocking.

[0044] like Figure 1-4 As shown, the manual unlocking module 4 also includes a compression spring 45, the elastic direction of the compression spring 45 is consistent with the extension direction of the push rod 2, one end of the compression spring 45 is connected to the unlocking rod 41, and the other end is connected to the electronic lock bottom cover 12; a card slot 411 is provided on the end of the unlocking rod 41 away from the spring, and a buckle 421 is provided at one end of the pull rope 42 that is engaged with the card slot 411. A mounting groove is provided on one side of the electronic lock bottom cover 12, and the electronic lock bottom cover 12 is detachably connected to a mounting seat 124 through the mounting groove. An inner cavity for accommodating the connecting part of the pull rope 42 and the unlocking rod 41 is formed in the mounting seat 124, and the mounting seat 124 is connected to a cover body 125, and the cover body 125 cooperates with the mounting seat 124 to form a channel that facilitates the extension and retraction of the pull rope 42.

[0045] A mounting groove is pre-set on one side of the electronic lock bottom cover 12. The shape of this mounting groove matches the bottom design of the mounting base 124 and is rectangular or in the shape of a guide slot. Guide rails or clips can be provided on both sides of the mounting groove to more securely fix the mounting base. The bottom of the mounting base 124 has corresponding protrusions that match the mounting groove. During installation, the mounting base can be pushed along the mounting groove on the electronic lock bottom cover 12 by sliding. The guide rails guide the mounting base to ensure a tight fit between the mounting base and the bottom cover. Alternatively, the protrusion at the bottom of the mounting base 124 can be designed as a clip structure. After sliding it into place, the clip engages with the locking structure of the mounting groove (such as a built-in spring leaf or hook), ensuring that the mounting base is firmly fixed and preventing loosening due to vibration or external force. To increase the fixing strength, screw holes can be designed on both sides of the mounting groove or on the edge of the mounting base 124. After the mounting base is pushed into the mounting groove, it is firmly fixed to the electronic lock bottom cover 12 with screws to ensure a stable and durable connection. Screw fixation can serve as a supplement to the sliding and snap-on structure, especially when stronger fixation is required, the screws provide additional security. When disassembly is required, the connection between the mounting base and the mounting slot can be released by releasing the snap (for example, pressing the spring sheet on the side of the mounting slot). By gently pushing and pulling, the mounting base can slide out from the bottom cover, which is convenient and quick to disassemble and assemble. If screw fixation is adopted, when disassembling, you only need to use a screwdriver to loosen the screws, and you can easily separate the mounting base 124 from the bottom cover 12, which is easy to operate. A sealing ring or a sealing gasket can be designed at the connection between the mounting base and the bottom cover to ensure that it has dustproof and waterproof functions after connection, and protect the pull rope 42 and the unlocking rod 41 from the external environment. The electronic lock bottom cover 12 and the mounting base 124 are detachably connected by a combination of sliding, snap-on and screws of the mounting slot. This design not only ensures the stability of the connection, but also provides the convenience of quick disassembly and assembly, which is convenient for maintenance and replacement. This structural design is very suitable for occasions where frequent maintenance and overhaul are required, while ensuring the sealing and stability of the system. Quick disassembly and assembly: Reference Figure 9 , Figure 10 Mounting base 124 and cover 125 are removably connected through a combination of sliding, snapping, and screwing in mounting slots, allowing for quick removal and replacement of the components connecting the pull cord 42 and release lever 41. This design facilitates maintenance and overhaul, allowing for quick removal and inspection or replacement of damaged components, minimizing downtime. Because each component can be removed and replaced independently, repairs require replacing only the faulty component, eliminating the need to replace the entire electronic lock assembly, thus reducing maintenance costs.

[0046] During installation, one end of the compression spring 45 is connected to the unlocking rod 41 and the other end is connected to the bottom cover 12 of the electronic lock, ensuring that the direction of the spring's elastic force is consistent with the telescopic direction of the push rod. Then, the buckle 421 provided at one end of the pull rope 42 is clipped into the slot 411 of the unlocking rod 41 away from one end of the spring to ensure a firm connection. The mounting base is clipped into the mounting slot so that the connecting portion between the unlocking rod and the pull rope is located in the inner cavity of the mounting base 124, ensuring that the pull rope can be freely extended and retracted. The cover 125 and the mounting base 124 are installed in coordination to ensure that the two form a complete pull rope telescopic channel (i.e., a strip chute) to protect the pull rope from being affected by the external environment during use. By designing a snap-fit ​​structure (slot 411 and buckle 421) between the unlocking rod 41 and the pull rope 42, it is ensured that the pull rope and the unlocking rod can be firmly connected during manual unlocking operation, preventing unlocking failure caused by loosening, thereby improving the reliability and safety of the unlocking operation. The compression spring 45 provides additional elastic support, so that the unlocking rod can be quickly reset after manual unlocking, ensuring a smooth unlocking process and preventing the unlocking rod from staying in a non-working position and affecting subsequent operations. The direction of the elastic force of the compression spring is consistent with the extension direction of the push rod 2, further enhancing the coordination of the components during the unlocking process. The bottom cover 12 of the electronic lock is detachably connected to the mounting base 124 through a mounting groove, so that the connecting parts of the pull rope 42 and the unlocking rod 41 can be quickly disassembled and replaced, which is convenient for inspection and operation of these key components during repair or maintenance, reducing downtime and improving maintenance efficiency. The mounting base 124 cooperates with the cover body 125 to form a pull rope telescopic channel, which protects the normal operation of the pull rope 42 and prevents it from being worn or damaged by the outside world during use. This design improves the integration and compactness of the system and effectively extends the service life of the components.

[0047] like Figure 1-4 As shown, the electronic lock module 3 comprises a drive motor 31, a driven gear 32, and a screw 33. The screw 33 comprises a screw 331 and a connecting block 332. The connecting block 332 has a screw hole on its rear side that is threadedly connected to the screw 331, and is connected to the push rod on its front side. A guide rail is provided on the bottom cover of the electronic lock, and a guide groove corresponding to the guide rail is provided on the underside of the connecting block. The driven gear 32 is connected to the output end of the drive motor 31, and the screw 33 is fixed to the center hole of the driven gear 32. This is the core power source of the electronic lock module and controls the extension and retraction of the push rod. The driven gear is connected to the output end of the motor, and the screw is fixed to the center hole of the driven gear. The screw rotates to convert the motor's rotational motion into linear motion of the connecting block. One side of the connecting block is threadedly connected to the screw, and the other side is connected to the push rod. Driven by the driven gear, the connecting block moves along the guide rail, driving the push rod to lock or unlock. A guide groove corresponding to the guide rail is provided on the underside of the connecting block to ensure stable movement.

[0048] like Figure 3-4As shown, a hook 44 is provided on the unlocking rod 41, and a slot is formed on one side of the connecting block 332 to engage with the hook 44. This structure ensures that when manually unlocking, the unlocking rod is in reliable contact with the connecting block, thereby effectively releasing the locked state of the push rod.

[0049] like Figure 1-4 As shown, the electronic lock for the vehicle-side charging socket further includes a housing 1, in which the electronic lock module 3 and the manual unlocking module 4 are housed. The push rod 2 can be extended relative to the housing 1. This ensures the overall compactness of the electronic lock and also makes installation and maintenance more convenient.

[0050] like Figure 1-4 As shown, the pull cord 42 is connected to the unlocking rod 41 and extends from the electronic lock housing 1. It ensures that the user can easily pull the unlocking rod through the pull cord, thereby manually unlocking when the electronic system fails, providing a convenient emergency operation mode.

[0051] like Figure 5-8 As shown, the electronic lock housing 1 is provided with a connector 5, a PCBA 6 and two tact switches 7 located on one side of the connecting block 332. Grooves 8 corresponding to the two tact switches 7 are provided at both ends of one side of the connecting block 332. When the connecting block 332 slides back and forth, the two tact switches 7 are triggered respectively. The connector 5 and the two tact switches 7 are electrically connected to the PCBA 6. A socket 13 for accommodating the connector 5 is formed on one side of the electronic lock housing 1. The connector is a cable or pin header. For reference, see the structural diagram of the connector when it is a cable. Figure 5 , refer to the structural diagram when the connector is a pin header Figure 3 , the pin header matches the connection socket 131 (such as Figure 4 As shown), the cable is matched with a silicone piece 132 (as Figure 6 As shown), the connection socket 131 and the silicone piece 132 are both matched with the socket 13 (as shown Figure 4 and 6(As shown), PCBA6 features perforated solder pads, through which the cable and pin headers connect to the PCBA6. The silicone insert features through-holes for the cable routing. By standardizing the assembly structure of the electronic lock's bottom shell, production can be tailored to individual customer needs, using materials for the corresponding cable or pin header connections. This allows for rapid production of customized electronic lock products. A connector designed on one side of the electronic lock housing accommodates the connector, simplifying cable or pin header connection and reducing complex installation steps. The matching design of the connector and silicone insert ensures a secure and reliable connection, effectively improving system assembly efficiency. The cable and pin headers connect to the PCBA via perforated solder pads, with the holes aligned, allowing for quick switching based on customer needs. The silicone insert provides flexible protection for the cable, preventing wear and breakage in the operating environment. The matching design of the connector's structure and shape ensures the system's excellent dust and water resistance, making it suitable for a variety of complex usage scenarios. The unified design of connectors accommodates standardized components such as flat cables and pin headers, simplifying installation and enabling faster and more efficient assembly of components during production, reducing debugging time. Accessories such as flat cables, pin headers, and silicone components are highly versatile and can be adapted to different models and specifications of electronic locks. This universal design facilitates rapid switching and adjustment of production lines, reduces reliance on specific components, and shortens preparation time during switching. The modular design of connectors and PCBAs allows for the rapid replacement or updating of modules between production stages or product models, facilitating flexible switching between different models of electronic locks and improving production efficiency. Since the flat cables and pin headers connect to the PCBA via perforated pads, this stable connection reduces the time required for repeated debugging and testing during production, lowering the failure rate during production switching and further shortening the product switching cycle.

[0052] like Figure 1-4 As shown, the two tact switches 7 are lock switch contacts 71 and unlock switch contacts 72. When the electronic lock module 3 drives the connecting block 332 to abut against the lock switch contacts 71 or unlock switch contacts 72, the PCBA 6 controls the electronic lock module 3 to stop working. The PCBA stops the drive motor in response to the signal, ensuring the push rod is accurately positioned and preventing excessive operation, thereby improving system reliability and efficiency.

[0053] When the PCBA receives a lock or unlock command, it sends a signal to the electronic lock module, driving the motor to start working. The operation of the motor drives the driven gear to rotate, thereby starting to drive the entire locking or unlocking process. The rotation of the driven gear drives the screw to rotate. The screw is connected to the connecting block through a thread, and the rotation of the screw converts this rotational motion into linear motion of the connecting block. The linear motion of the connecting block directly drives the push rod to extend or retract it. Among them,

[0054] Locking operation: When the push rod extends outward during linear motion, the locking mechanism of the charging pile will be locked by the push rod to ensure that the charging pile is in a locked state.

[0055] Unlocking operation: When the push rod is retracted, the locking mechanism of the charging pile is released and the charging pile enters the unlocked state.

[0056] When the connecting block moves in the bar-shaped slide, it drives the unlocking lever shaft to slide synchronously. This movement ensures the synchronization of locking and unlocking operations through linkage with the push rod, so that the unlocking lever shaft maintains the correct relative position during the locking and unlocking process. When the push rod moves to the specified locked or unlocked position, the groove on the connecting block triggers the lock switch contacts or unlock switch contacts respectively. The trigger signals of these tactile switches are transmitted to the controller through the PCBA (printed circuit board assembly), and the controller determines whether the operation is complete based on the signal. Once the signal from the tactile switch is received through the PCBA, confirming that the push rod has reached the final locked or unlocked position, the PCBA will immediately send a signal to stop the drive motor and prevent the push rod from moving further, thereby protecting the various components of the system and saving energy.

[0057] When the electronic lock module fails or needs to be unlocked urgently, the user can manually unlock it by pulling the rope. When the user pulls the rope, the rope drives the unlocking rod 41 to move backward, and then drives the connecting block to slide backward. This manual operation can release the locking state of the push rod and realize manual unlocking of the charging pile. During manual unlocking or retraction of the push rod, the elastic member (compression spring) plays a role to help the push rod reset. The elastic member provides the necessary elastic force to ensure that the unlocking rod and the push rod can smoothly return to their initial position, ensuring the stability of the system after manual operation.

[0058] The entire workflow is electronically controlled, achieving automatic locking and unlocking, offering both efficient automation and manual emergency response capabilities. The actuator's movement is driven by a motor via a lead screw, with feedback from a touch switch ensuring precise operation. In the event of system failure, the manual release module provides a safe and reliable emergency release, with an elastic member assisting in reset, ensuring smooth and safe operation.

[0059] The electronic lock module is the core driving component of this utility model. An electric motor drives the lead screw-nut structure to achieve linear motion of the push rod. This drive allows the push rod to precisely extend and retract, completing the locking and unlocking functions. This automated control method not only simplifies the user's operation process but also improves the system's responsiveness, making it particularly suitable for applications requiring rapid locking and unlocking, such as public charging stations. To ensure the reliability and accuracy of locking and unlocking, the system features two tactile switches at either end of the push rod's travel. When the push rod reaches the locked or unlocked position, the corresponding tactile switch is triggered, providing feedback to the PCBA (printed circuit board assembly). Upon receiving this signal, the PCBA immediately stops the electronic lock module, preventing further movement of the push rod and avoiding issues like over-tightening or incomplete locking. This feedback mechanism significantly improves the lock's control precision, ensuring the accuracy and safety of each locking and unlocking operation. In the event of electronic system failure or anomaly, the system provides a manual unlocking module as a backup. This module, with its pull cord and unlocking lever, allows the user to quickly manually release the lock in an emergency. The close coordination of the pull cord and the release lever ensures reliable operation, allowing users to quickly unlock the device even in the event of a power failure. This improves the system's emergency response capabilities and enhances the safety of the charging station. Both the electronic lock module and the manual release module are independently encapsulated within the electronic lock housing. This modular design effectively protects the electronic and mechanical components within each module from environmental influences, extending the system's service life. The modular structure also facilitates maintenance and replacement. Maintenance personnel only need to remove and replace individual modules when necessary, without having to dismantle the entire lock, significantly improving maintenance efficiency and reducing repair costs. The mechanical transmission system utilizes a screw-nut structure. Compared to complex gear or belt drives, this structure is simpler and more reliable, providing stable transmission performance within limited space. The rotation of the screw enables the push rod to precisely move in a straight line, enabling efficient locking and unlocking operations. Furthermore, this structure offers a high load capacity and a long service life, reducing the failure rate of the transmission system and significantly improving the overall reliability of the system. The overall design of this utility model is very compact, integrating the electronic lock module, push rod, guide rail, and manual release components into a single housing. This compact design is ideal for installation in space-constrained equipment such as charging stations, and is particularly advantageous when deployed in urban public facilities or confined spaces. The modules fit tightly together within the housing, reducing wasted space and minimizing system size while maintaining system stability. Through feedback from a touch switch, the electronic lock module operates only when necessary. When the push rod reaches the designated locked or unlocked position, a feedback switch immediately signals the controller to stop the motor.This precise control based on real-time feedback greatly reduces unnecessary energy consumption and avoids the situation where the motor runs for a long time or idles, thereby achieving the energy-saving effect of the system and extending the battery or power supply life. It is particularly suitable for frequently used charging pile scenarios. Due to the modular design, the charging pile electronic lock of the present invention is very simple in production and installation. Each module can be assembled and tested independently, reducing the complex processes in the production process. At the same time, the modular design also makes the system highly scalable and can flexibly adjust the configuration according to the needs of different charging piles, thereby meeting the usage requirements of different scenarios. The charging pile electronic lock of the utility model realizes efficient, stable and intelligent locking and unlocking functions through technologies such as automatic drive, manual emergency unlocking, modular packaging and screw-nut transmission. It has a simple and compact structure and is easy to install. It is suitable for large-scale application in public charging pile scenarios, and at the same time has high reliability, durability and energy saving. This design not only improves the user's convenience, but also provides an effective solution for the management and maintenance of charging piles.
