Description

Technical Field

[0001] This application relates to the field of charging pile technology, specifically to a shared lock and charging pile system for home charging guns. Background Technology

[0002] With the rapid development of the electric vehicle industry, the number of home charging stations installed has continued to grow. Many private charging stations experience significant periods of idle time, creating a strong demand for sharing. This means that station owners hope to share their charging stations during off-peak hours to improve resource utilization efficiency and generate additional revenue. This time-sharing rental-based sharing model can theoretically effectively alleviate the pressure of insufficient public charging infrastructure and promote the optimal allocation of social resources.

[0003] However, the widely deployed home charging stations are designed only to meet the personal needs of car owners and generally lack the necessary functional support for shared scenarios.

[0004] Therefore, there is an urgent need in this field for a new type of smart lock to fundamentally overcome the limitations of traditional mechanical locks and enable the home charging gun to meet the development needs of subsequent shared scenarios. Summary of the Invention

[0006] A first aspect of this application provides a shared lock for a household charging gun, including a lock base and a locking mechanism, a bolt, a drive assembly, and a control unit disposed within the lock base; The lock base is provided with a receiving cavity for accommodating the charging gun; The locking mechanism is disposed in the receiving cavity, and its structural position corresponds to the hook of the charging gun so as to form a locking engagement with the hook when the charging gun is inserted. The locking tongue is movably disposed within the lock seat and is connected to the drive assembly for transmission. The drive component is electrically connected to the control unit and is controlled by the control unit to execute corresponding drive actions. The latch is configured to prevent or allow the hook to disengage from the locking mechanism when driven by the drive assembly.

[0007] In one embodiment, the lock seat is provided with a slide rail, and the lock tongue is slidably disposed in the slide rail, the sliding direction of which is configured to intersect with the disengagement path of the hook. The drive assembly is configured to drive the latch to move linearly within the slide, so that the latch enters the space above the hook to prevent the hook from disengaging from the locking mechanism, or to cause the latch to exit the space above the hook to allow the hook to disengage from the locking mechanism.

[0008] In one embodiment, the drive assembly includes a motor, a rocker arm driven to rotate by the motor, and a drive shaft with one end hinged to the rocker arm and the other end connected to the latch, the latch being used to make linear motion under the drive of the motor.

[0009] In one embodiment, a micro switch is also provided inside the lock seat. The trigger end of the micro switch is located inside the receiving cavity and is used to detect whether the charging gun is in place. The signal output end of the micro switch is electrically connected to the signal input end of the control unit.

[0010] In one embodiment, the control unit is configured to: When the micro switch detects that the charging gun is inserted into place, the drive assembly is controlled to drive the locking tongue to move to a first position that prevents the hook from disengaging from the locking mechanism. When an unlocking command is received, the drive assembly is controlled to move the bolt to a second position that disengages the hook from the locking mechanism.

[0011] In one embodiment, the surface of the lock base is provided with a QR code marking area.

[0014] In one embodiment, the communication unit is a narrowband Internet of Things (IoT) communication unit.

[0015] A second aspect of this application provides a charging pile system, including a home charging pile and a shared lock as described above, wherein the lock base of the shared lock is fixedly installed on the home charging pile.

[0016] The first aspect of this application provides a shared lock for home charging guns. This lock, through an intelligent intervention mechanism controlling the latch's disengagement path under the control of a drive component, replaces the key or password operation of traditional mechanical locks, achieving automated locking and releasing driven by remote commands. Charging stations using the aforementioned home charging guns, in conjunction with relevant control algorithms, can physically allow or prohibit the removal of the charging gun through controlled movement of the latch. This allows charging station owners to remotely and securely grant charging access, providing an indispensable hardware foundation for time-sharing rental-style sharing. It fundamentally overcomes the limitations of traditional mechanical locks, enabling locks specifically designed for home charging guns to meet the development needs of subsequent sharing scenarios.

[0017] It is understandable that the beneficial effects of the second aspect mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here. Attached Figure Description

However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0021] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0025] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0026] like Figure 1 As shown in the figure, the shared lock for a household charging gun provided in this application embodiment includes a lock base 1 and a locking mechanism 6, a lock tongue 5, a drive assembly 102 and a control unit 101 disposed in the lock base 1; The lock base 1 has a receiving cavity 2 for accommodating the charging gun; The locking mechanism 6 is located in the receiving cavity 2, and its structural position corresponds to the hook 7 of the charging gun so as to form a locking engagement with the hook 7 when the charging gun is inserted. The locking tongue 5 is movably disposed within the lock base 1 and is connected to the drive assembly 102 in a transmission manner; The drive component 102 is electrically connected to the control unit 101 and is controlled by the control unit 101 to perform corresponding drive actions. The locking tongue 5 is configured to prevent or allow the hook 7 to disengage from the locking mechanism 6 when driven by the drive assembly 102.

[0027] In application, the outer shell of the lock seat is made of fire-resistant engineering plastic. The end points of the lock tongue's travel include a first position and a second position. In the first position, the movement trajectory of the lock tongue inserting into the hook creates physical interference to prevent disengagement. In the second position, the lock tongue completely exits the interference area, making way for the hook to disengage.

[0028] In application, the shared lock's working states include locked and unlocked states. When the charging gun is inserted into the receiving cavity, the bolt is in the pop-out state, filling the space above the hook. The hook is secured by the locking mechanism and cannot be lifted, thus reliably locking the charging gun. The charging gun head is in a locked, unchargeable, and unusable state, meaning the shared lock is in the locked state. When the shared lock's control unit receives an unlocking command, the motor drives the bolt to retract, releasing the space above the hook. The user presses the charging gun button, the hook lifts up and disengages from the locking mechanism, and the charging gun can be freely removed for use. The charging gun head is in an unlocked, rechargeable, and usable state, meaning the shared lock is in the unlocked state. The working status display on the lock base panel relies on the shared lock's working status detection mechanism. The shared lock detects the charging gun head's working status in real time based on the state of the microswitch. The status signal is transmitted to the control unit for processing. The control unit controls the display status, and simultaneously, the control unit uploads the status information to the cloud management platform 109 through the shared lock's communication unit 108, i.e., the NB-IoT module.

[0029] This application embodiment replaces the key or password operation of traditional mechanical locks by using an intelligent intervention mechanism that controls the latch's disengagement path under the control of the drive component, achieving automated locking and releasing driven by remote commands. Charging stations using the aforementioned household charging gun can, in conjunction with relevant control algorithms, physically allow or prohibit the removal of the charging gun through controlled movement of the latch. This enables charging station owners to remotely and securely grant charging access, providing an indispensable hardware foundation for realizing time-sharing rental-style sharing.

[0030] In one embodiment, the lock base 1 is provided with a slide rail 9, and the lock tongue 5 is slidably disposed in the slide rail 9, and its sliding direction is configured to intersect with the disengagement path of the hook 7. like Figure 2As shown, the drive assembly 102 is configured to drive the latch 5 to move linearly within the slide rail 9, so that the latch 5 enters the space above the hook 7 to prevent the hook 7 from disengaging from the locking mechanism 6, or to cause the latch 5 to exit the space above the hook 7 to allow the hook 7 to disengage from the locking mechanism 6.

[0031] In application, the lock seat body is molded with a straight slide structure through injection molding. The guide protrusions on both sides of the latch form a sliding fit with the guide grooves on the inner wall of the slide. The sliding direction of the latch intersects perpendicularly with the tangent direction of the arc motion when the hook disengages. The front end of the latch can adopt a wedge design. When it moves along the slide to directly above the hook, the wedge surface maintains a preset gap with the top surface of the hook to achieve an obstruction function. When the latch moves in the opposite direction to the end of the slide, its front end retracts completely into the lock seat housing, thereby clearing the space above the hook.

[0032] This application's embodiments introduce a slide structure and define the spatial relationship between the locking tongue's movement path and the hook's disengagement path. The slide provides precise guidance and support for the locking tongue's linear movement, effectively preventing the locking tongue from deviating or jamming when under force. By configuring the sliding direction to intersect with the hook's disengagement path, it geometrically ensures that the locking tongue can achieve its blocking function through the most direct mechanical interference. This structural design significantly improves the reliability and repeatability of the locking action, while the linear movement reduces the design complexity of the drive mechanism, facilitating control and maintenance.

[0033] In one embodiment, such as Figure 3 , 4 As shown, the drive assembly 102 includes a motor 3, a rocker arm 4 driven to rotate by the motor 3, and a transmission shaft 8 with one end hinged to the rocker arm 4 and the other end connected to the locking tongue 5. The locking tongue 5 is used to make linear motion under the drive of the motor 3.

[0034] In this application, the drive assembly includes a DC motor. The motor's output shaft is connected to a rocker arm. The free end of the rocker arm forms a rotating pair with a drive shaft via a pin. The other end of the drive shaft has an external thread that mates with a threaded hole at the bottom of the latch. When the motor rotates forward, the rocker arm pushes the drive shaft forward along a linear guide, causing the latch to extend. When the motor rotates in reverse, the rocker arm pulls the drive shaft backward, causing the latch to retract. A retaining ring can be installed at the connection between the drive shaft and the latch to prevent axial disengagement. The DC motor drives the latch by rotating forward or in reverse.

[0035] This application embodiment specifies a drive component consisting of a motor rocker arm and a drive shaft. This transmission scheme has significant mechanical advantages. The rotational power provided by the motor is converted into a large-thrust linear motion of the drive shaft through the rocker arm. This can overcome the static friction when the lock tongue slides to ensure that the action is in place. The hinged connection allows for a certain assembly tolerance, reduces the requirements for the machining accuracy of parts, and the entire transmission chain structure is compact with high power transmission efficiency. Moreover, the extension and retraction of the lock tongue can be precisely controlled by the forward and reverse rotation of the motor, realizing an efficient conversion between electrical control and mechanical execution.

[0036] In one embodiment, a micro switch 103 is also provided in the lock base 1. The trigger end of the micro switch 103 is located in the receiving cavity 2 and is used to detect whether the charging gun is in place. The signal output end of the micro switch 103 is electrically connected to the signal input end of the control unit 101.

[0037] In application, the micro switch is fixed in the receiving cavity, and its reed trigger end extends to the insertion and removal path of the charging gun. When the charging gun is inserted, the gun head housing presses the reed to close the normally open contact inside the micro switch. The switch signal is transmitted to the optocoupler input of the control unit through the shielded cable. The control unit is equipped with a debounce algorithm to filter the signal. The trigger pressure value of the micro switch can be set to 2 Newtons to ensure reliable detection.

[0038] The microswitch added in this embodiment forms the basis of the device's state perception, converting the physical event of plugging and unplugging the charging gun into an electrical signal, providing a key input for the control logic. The trigger end of the microswitch is located inside the receiving cavity, enabling direct and non-destructive detection of the gun's presence. This detection method is more immediate and accurate than indirect inference, such as through current detection. After the signal is transmitted to the control unit, the system can perceive the start and end points of the user's operation, providing the necessary conditions for subsequent automatic control, such as automatic locking after the gun is returned to its position, thus improving the system's intelligence level.

[0039] In one embodiment, the control unit 101 is configured to: When the micro switch 103 detects that the charging gun is inserted into place, the control drive assembly 102 drives the locking tongue 5 to move to the first position that prevents the hook 7 from disengaging from the locking mechanism 6. When an unlocking command is received, the control drive assembly 102 drives the bolt 5 to move to the second position where the latch 7 disengages from the locking mechanism 6.

[0040] In application, after the micro switch contacts are closed, the control unit confirms that the gun body is fully in place, and then sends a control signal to the drive component to move the bolt to the first position. When the control unit receives the unlocking command issued by the cloud management platform through the serial communication interface, it sends a control signal to drive the bolt to the second position.

[0041] In this embodiment, the device automatically locks when the charging gun is detected to be inserted, ensuring security and theft prevention during usage intervals. Upon receiving an authorization command from the cloud, the device unlocks, enabling remote management and access control. This organically combines hardware status detection with network communication commands, forming a complete automated control loop, reducing manual intervention and ensuring the smoothness and security of the sharing process.

[0042] In one embodiment, the surface of the lock base 1 is provided with a QR code marking area.

[0043] In application, the QR code 110 identification area can be formed into a QR code matrix on the surface of the lock base using UV inkjet printing process. The matrix code includes the device's unique identification code and the server access address, and the identification area surface is covered with a scratch-resistant optical coating.

[0044] This application embodiment uses standardized image encoding technology to solidify complex device identification and network address information on the lock body surface. Users can quickly and accurately initiate service requests through a common scanning action, avoiding errors that may occur when manually entering device numbers. This access method has a low threshold and high reliability, providing technical convenience for the rapid promotion of shared services.

[0045] In one embodiment, such as Figure 5 As shown, it also includes a status display unit 104 and / or an audio-visual prompt unit 105, which are electrically connected to the control unit 101.

[0046] In application, the status display unit can be arranged on the front panel of the lock base using a combination of 7-segment digital tubes and RGB three-color LEDs; the sound and light prompt unit can include a piezoelectric buzzer and multi-color indicator lights embedded in the light-transmitting holes of the panel. The display unit can receive byte data packets sent by the control unit via the I2C bus, and the sound and light unit can generate prompt sounds and red, green and blue three-color flashing patterns according to different frequency square wave signals output by the control unit. All prompt components are waterproof and sealed to the lock base housing through sealing rings.

[0047] The status display and audio-visual prompt unit integrated in this application embodiment constructs an important human-computer interaction channel. The status display unit can continuously and intuitively present key information such as the lock's power level and locking status, while the audio-visual prompt module can provide clear feedback to the user through sound and light changes when the operation is completed, such as when the lock is successfully unlocked. This multimodal feedback mechanism greatly improves the user experience, enabling users to quickly confirm the device status and operation results, and reducing confusion or misoperation caused by unclear status.

[0048] In one embodiment, it further includes a communication unit 108 and a power supply unit 106; Communication unit 108 is electrically connected to control unit 101; The power supply unit 106 is a rechargeable battery pack and is equipped with a charging interface 107 for supplying power to the control unit 101, the drive assembly 102 and the communication unit 108.

[0049] In this application, the communication unit uses an NB-IoT module supporting the Band 5 frequency band, soldered onto the main control PCB board. Its ceramic antenna is embedded inside the non-metallic area of ​​the lock seat. The power supply unit uses 18650 lithium-ion cells to form a battery pack, which accepts charging via a Type-C interface. A power management chip can also be configured to monitor the battery voltage in real time and send a low-battery alarm signal to the control unit when it falls below 3.3 volts. The communication unit and power supply unit are electrically interconnected with the control unit via an FPC cable.

[0050] The communication unit in this embodiment is responsible for maintaining real-time data exchange between the device and the cloud, enabling remote monitoring and control. The dedicated power supply unit provides stable energy to all electronic components, and its rechargeable feature meets the needs of long-term outdoor use, thus forming a fully functional IoT terminal hardware foundation.

[0051] In one embodiment, the communication unit 108 is a narrowband Internet of Things (IoT) communication unit.

[0052] The communication unit in this application embodiment is limited to a narrowband IoT module, which has the characteristics of wide coverage, low power consumption and large connectivity. It is suitable for application scenarios where shared locks are distributed and require long battery life. Its strong wall penetration capability ensures the stability of the communication link in complex environments, while the low power consumption directly extends the battery life and reduces the maintenance frequency.

[0053] This application embodiment also provides a charging pile system, including a home charging pile and a shared lock as described above, wherein the lock base 1 of the shared lock is fixedly installed on the home charging pile.

[0054] In application, the shared lock of the charging pile system is fastened to the mounting plate of the charging pile column by bolts at the bottom of the lock seat. The cable outlet of the lock seat is connected to the internal cable of the charging pile using a waterproof gland. The main controller of the charging pile exchanges status information with the shared lock control unit through the CAN bus. The system is equipped with a ground fault circuit breaker to ensure that the metal shell of the shared lock is reliably grounded.

[0055] In applications, such as Figure 5As shown, the charging pile system also includes a cloud management platform 109. Users can scan the QR code 110 in the QR code identification area above the shared lock seat and send an unlocking request to the cloud management platform 109 via a mobile app. The cloud management platform 109 and the control unit 106 interact via a communication unit 108. The power supply unit 106 supplies power to the control unit 101 and other modules, and can also be charged via the charging interface 107. The control signal output terminal of the control unit 101 is connected to the drive assembly 102, used to drive the lock tongue to the first or second position. The micro switch 103 is used to detect whether the charging gun is located within the receiving cavity 2. The data output terminal of the control unit 101 is connected to the status display unit 104 and the audio-visual prompt unit 105, respectively, to display the charging gun's relevant status and output audio-visual prompt signals.

[0056] The working principle of this system is as follows: During the unlocking phase: Users use a dedicated application on their mobile devices to locate and navigate to nearby home charging stations that are available for sharing. Upon arrival, users scan a QR code on the surface of the shared lock, which encodes the device's unique identification information. The application then sends an unlocking request containing the user's identity and device identifier to the cloud management platform. Upon receiving the request, the cloud management platform first verifies the legitimacy of the user's identity and the validity of the payment authorization. It then checks the current status of the target shared lock to see if it is locked and verifies the sharing policy set by the charging station owner (such as the available time period). After all verifications are successful, the cloud management platform sends an encrypted digital unlocking command to the shared lock's NB-IoT communication module via a wireless communication network. The control unit inside the shared lock receives and parses the command, then generates a drive signal to control the motor, retracting the bolt from its obstructed position to its open position via a rocker arm. Simultaneously, after successfully sending the command, the cloud management platform sends a confirmation message to the user's mobile application, indicating that the unlocking operation has been performed, and the user interface updates to a usable state. At this point, the user can manually press the button on the charging gun to lift its hook, thereby pulling the charging gun out of the locking seat's receiving cavity.

[0057] Working Status Monitoring: After the charging gun is removed, the microswitch inside the lock seat changes its trigger state (e.g., from closed to open), immediately sending a status signal indicating that the charging gun has been removed to the control unit. While driving the bolt and receiving sensor signals, the control unit continuously monitors key parameters such as the bolt position, motor operating current, and power supply unit voltage in real time. Through the NB-IoT communication module, the control unit stably transmits real-time working status data of the shared lock (including but not limited to status indicators such as "charging gun removed," "starting charging," and "working") to the cloud management platform using a combination of timed heartbeat packets and event-triggered reporting. Upon receiving the "start charging" signal, the cloud management platform starts a high-precision timer for billing and can push information such as current usage time and accumulated fees to the user's mobile terminal application in real time or periodically, ensuring transparency in the billing process.

[0058] Locking Phase: After charging is complete, the user inserts the charging gun back into the shared lock's receiving cavity until it is fully seated. This action triggers a change in the state of the microswitch within the lock seat (e.g., from open to closed), and the "charging gun returned to position" signal is immediately sent to the control unit. Upon receiving this signal, the control unit automatically drives the motor to reverse its rotation without waiting for instructions from the cloud, using a transmission mechanism to eject the bolt from the yielding position to the obstructing position, completing the physical locking. After the locking action is completed, the control unit proactively reports the "charging gun returned to position" or "charging finished" status signal to the cloud management platform via the NB-IoT communication module. Upon receiving this signal, the cloud management platform immediately stops timing, calculates the final fee based on the preset rate, automatically completes the payment settlement process, and sends a charging completion notification containing a detailed bill to the user's mobile terminal application.

[0059] Through the continuous operation of the above three stages, the entire process of home charging pile sharing, from authorized use to status monitoring and settlement and locking, has been automated and intelligently managed.

[0060] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
