Description

Technical Field

[0001] This utility model relates to a locking mechanism, specifically a locking mechanism, a battery charging compartment, and a shared battery cabinet. Background Technology

[0002] With the development of the sharing economy, battery sharing devices are increasingly appearing on the market, such as shared battery cabinets for electric vehicles. When a user needs a battery, they can scan a QR code or enter a password to open the cabinet and retrieve the battery. In some battery cabinets, users simply insert the battery into the battery compartment and push it all the way in to connect it to the charging port. However, while this method makes returning batteries convenient, it still requires ensuring a stable connection between the battery and the charging port. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a locking mechanism, a battery charging compartment, and a shared battery cabinet. The locking mechanism provides a locking function and, when used in a battery charging compartment, can improve the stability of the fit between the battery and the charging interface. At the same time, it can realize the convenient locking and unlocking of the locked components (such as batteries) and improve the reliability of use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A locking mechanism, comprising a rotating rod, a plurality of locking hooks fixedly connected to the rotating rod, a locking element, and an actuating component; the rotating rod is used to synchronize the movement of the plurality of locking hooks; the locking hooks lock or unlock external components to be locked by rotating; the locking element is linked with the actuating component and is driven by the actuating component to move, thereby restricting or releasing the rotation of the locking hooks.

[0005] As a further improvement of this utility model, the locking member is provided with a limiting part for restricting the rotation of the lock hook. When the locking member restricts the rotation of the lock hook, the position of the lock hook corresponding to the limiting part is located on the limiting part, and the limiting part restricts the lock hook from rotating in the unlocking direction. When the locking member moves and the limiting part separates from the lock hook, the limiting part releases the restriction on the lock hook from rotating in the unlocking direction.

[0006] As a further improvement of this utility model, at least one of the locking hooks is connected to an elastic element, and the locking hook is kept in a rotating direction toward the unlocking direction by the elastic element.

[0007] As a further improvement of this utility model, the upper limit portion of the locking member is also used to cooperate with the side of the lock hook to abut against it. When the lock hook is in the unlocked position, the lock hook restricts the movement of the locking member.

[0008] As a further improvement of this utility model, it also includes a pop-out component, which is used to abut against the locking component, so that the component to be locked maintains the tendency to move in the disengagement direction. When the locking hook contacts the locking of the component to be locked, the pop-out component drives the component to be locked to disengage from the locking hook.

[0009] As a further improvement of this utility model, the execution component includes a motor assembly, and the output end of the motor assembly is provided with a linkage component, which drives the locking component to move through the linkage component.

[0010] As a further improvement of this utility model, the linkage component is a cam, and the locking component has a mating surface at the position corresponding to the cam. The output end of the motor assembly rotates to drive the cam to rotate and cooperate with the mating surface to drive the locking component to move.

[0011] As a further improvement of this utility model, the distance between the circumferential surface of the cam and the circumferential surface of the output end of the motor assembly continuously increases or decreases along the rotation direction of the cam.

[0012] As a further improvement of this utility model, the execution component also includes a return spring connected to the locking member; the motor assembly drives the locking member to move via a cam to release the restriction on the rotation of the lock hook, and the locking member is driven by the return spring to move in the direction that restricts the rotation of the lock hook.

[0013] As a further improvement of this utility model, the locking member is provided with a manual lever, which is used to manually move the locking member toward the direction of contacting and restricting the rotation of the lock hook.

[0014] As a further improvement of this utility model, the actuating component includes an electromagnetic pull rod, the telescopic rod of which is linked with the locking member to drive the locking member to move.

[0015] As a further improvement of this utility model, the execution component also includes a connector, which is rotatably connected about a fixed shaft, with one end hinged to the telescopic rod and the other end connected to the locking component. The electromagnetic pull rod drives the connector to rotate through the telescopic movement of the telescopic rod, thereby driving the locking component to move.

[0016] As a further improvement of this utility model, a manual lever is provided on the telescopic rod, which is used to manually move the telescopic rod.

[0017] A battery charging compartment is also provided, including a receiving compartment, a power interface located within the receiving compartment, and a locking mechanism as described in any one of the above, the locking mechanism being used to lock or unlock a battery placed in the receiving compartment.

[0018] A shared battery cabinet is also provided, including the battery charging compartment described above.

[0019] The beneficial effects of this invention are as follows: the locking mechanism achieves synchronous movement of several locking hooks through a rotating rod, which improves the consistency of the movement of multiple locking hooks and reduces the impact of individual hook failure or asynchrony on the overall locking effect. Simultaneously, the linkage between the locking component and the actuating component allows for flexible restriction or release of hook rotation, enhancing the controllability of locking and unlocking. This structure effectively improves the fixing effect of the component to be locked (such as a battery), provides support for the stable cooperation between the component to be locked and other components (such as a charging interface), and thus improves the overall reliability of the device (such as a battery charging compartment or shared battery cabinet). Furthermore, the overall structural design is simple, facilitating integration into various devices requiring locking functions, and exhibits good applicability. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0030] Reference Figure 1-8 As shown,

[0031] This embodiment provides a locking mechanism, including a rotating rod 1, a plurality of locking hooks 2 fixedly connected to the rotating rod 1, a locking element 3, and an actuation component 4; the rotating rod 1 is used to synchronize the operation of the plurality of locking hooks 2; the locking hooks 2 lock or unlock external parts to be locked by rotating; the locking element 3 is linked with the actuation component 4 and is driven by the actuation component 4 to move, so as to restrict or release the rotation of the locking hooks 2.

[0032] Rotating rod 1 can be rotatably mounted on a preset mounting base via bearings or bushings (or refer to...). Figure 1 As shown, it is directly filled into the groove and rotates within the groove. The position of the groove is blocked by a baffle to prevent the transmission rod from coming out. The locking hook 2 is fixed to the preset position of the rotating rod 1 by welding or threaded connection (or refer to...). Figure 1 , 2 The non-circular hole on the locking hook 2 and the corresponding structure on the transmission rod are matched to fix the rotation direction, and the screws are used to fix it so that it will not move in the axial direction of the rotating rod 1. The orientation and spacing of each locking hook 2 are adapted to the structure of the component to be locked. The locking component 3 is slidably set on the mounting bracket near the locking hook 2 through the slide rail or guide hole / groove. The execution component 4 is fixed to the preset position of the mounting base by bolts, and its output end is connected to the locking component 3 by a pin or hinge. When it is necessary to lock an external component (such as a battery), an external force drives the rotating rod 1 to rotate (for example, after the battery is pushed in, the position where it engages with the locking hook 2 opens the locking hook 2, causing the locking hook 2 to rotate, which in turn causes the transmission rod to rotate). At this time, the transmission rod drives all the locking hooks 2 to rotate synchronously. After the locking hook 2 aligns with the locking position of the locked component, it will rotate and lock under the action of gravity or the guidance of the guide surface, and lock in cooperation with the component to be locked. Then, the execution component 4 starts to act, driving the locking piece 3 to slide along the slide rail to the position of the corresponding locking hook 2, restricting the rotation of the locking hook 2, keeping the locking hook 2 in the locked position, thereby improving the fixed stability of the component to be locked and providing a basis for the cooperation of the component to be locked with other components (such as the charging interface). When it is necessary to unlock, the execution component 4 drives the locking piece 3 to slide along the slide rail, releasing the restriction on the rotation of the locking hook 2. An external force (i.e., directly pulling the component to be locked away) or an auxiliary mechanism drives the unlocking. The rotating rod 1 enables all the locking hooks 2 to rotate synchronously. This synchronous locking and unlocking method improves the consistency of the actions of multiple locking hooks 2, reduces the unreliability of locking caused by jamming or failure of a single locking hook 2, and enhances the controllability of the locking state by cooperating with the execution component 4 and the locking element 3, preventing accidental unlocking. It also reduces the use of drive devices, such as reducing the number of motors, and simplifies the structure.

[0033] To further improve the accuracy of the locking member 3 in restricting the rotation of the hook 2, in one optional embodiment, the locking member 3 is provided with a limiting part 31 for restricting the rotation of the hook 2. When the locking member 3 restricts the rotation of the hook 2, the position of the hook 2 corresponding to the limiting part 31 is located on the limiting part 31, and the limiting part 31 restricts the hook 2 from rotating in the unlocking direction. When the locking member 3 moves and the limiting part 31 separates from the hook 2, the limiting part 31 releases the restriction on the rotation of the hook 2 in the unlocking direction.

[0034] The limiting part 31 can be designed as a protruding structure, integrally formed on the side of the locking member 3 or in a hollowed-out position. The locking hook 2 has a flat or groove-shaped contact part corresponding to the limiting part 31. When the locking member 3 slides, the limiting part 31 can move with the locking member 3 to a position that fits or separates from the contact part of the locking hook 2. When the locking hook 2 rotates to the locked position, the actuator 4 drives the locking member 3 to slide, so that the limiting part 31 moves to one side of the contact part of the locking hook 2. At this time, if the locking hook 2 has a tendency to rotate in the unlocking direction, the limiting part 31 will abut against the contact part, blocking the rotation of the locking hook 2, thereby stably restricting the locking hook 2 in the locked position, reducing the small rotation of the locking hook 2 caused by vibration or external force interference, and further improving the stability of the lock. When unlocking is required, the actuator 4 drives the locking member 3 to slide in the opposite direction, causing the limiting part 31 to separate from the contact part of the locking hook 2. The rotation of the locking hook 2 in the unlocking direction is no longer blocked, and the unlocking action can be completed smoothly. This targeted limiting design can reduce the ineffective contact between the locking component 3 and the locking hook 2, improve the limiting efficiency, and at the same time reduce the wear between the locking hook 2 and the locking component 3, thus extending the service life of the components.

[0035] In order to maintain the unlocking trend even when the lock hook 2 is unlocked without external force, the following method can be selected for further optimization: at least one of the lock hooks 2 is connected to an elastic element 21, and the lock hook 2 maintains the tendency to rotate in the unlocking direction through the elastic element 21.

[0036] The elastic element 21 can be a spring, with one end fixed to the extension end of the locking hook 2 via a hook or pin, and the other end fixed to a pre-set protrusion on the mounting base. When the locking hook 2 rotates during the locking process (i.e., from the unlocked position to the locked position), the spring is stretched and deformed, accumulating elastic potential energy. During the unlocking operation, if the locking element 3 releases the rotation restriction on the locking hook 2, the spring will release the elastic potential energy, causing the locking hook 2 to automatically rotate in the unlocking direction until the locking hook 2 is completely separated from the part to be locked. No additional drive element is needed to drive the locking hook 2 to rotate, simplifying the drive structure for the unlocking operation. At the same time, it can also ensure that the locking hook 2 responds quickly to the unlocking action after the unlocking restriction is released, reducing unlocking delay. In addition, the preload of the elastic element 21 can be adjusted according to the weight and fixing requirements of the part to be locked, improving the adaptability of the mechanism to different parts to be locked and avoiding the problem of unsmooth unlocking due to insufficient driving force of the locking hook 2. It is especially suitable for scenarios such as shared battery cabinets that require quick unlocking and retrieval of parts.

[0037] Furthermore, as a preferred embodiment, the upper limit portion 31 of the locking member 3 is also used to abut against the side of the locking hook 2, so that when the locking hook 2 is in the unlocked position, the locking hook 2 restricts the movement of the locking member 3.

[0038] This abutting action can prevent the locking element 3 from moving accidentally when the hook 2 is in the unlocked state, thus preventing the hook 2 from rotating and locking.

[0039] In some options, to facilitate the smooth disengagement of the locking component from the hook 2 after unlocking and to prevent the locking component from getting stuck in the locked position, the following improvements can be made, including the pop-out component 5. The pop-out component 5 is used to abut the locking component and keep the locking component moving in the disengagement direction. When the hook 2 contacts the locking of the locking component, the pop-out component 5 drives the locking component to disengage from the hook 2.

[0040] The pop-out component 5 can be a compression spring, located at the bottom of the cavity accommodating the component to be locked. One end of the spring is fixedly connected to the bottom of the cavity, and the other end is connected to a top block for abutting the component. When the component to be locked is inserted into the cavity and locked by the hook 2, the component will press against the top block, causing the compression spring to contract and accumulate elastic force. When the hook 2 releases the component, the compression spring releases its elastic force, pushing the top block upwards or towards the cavity opening, thereby moving the component to be locked in the ejection direction, completely separating the component from the hook 2, making it easy for the user or subsequent mechanism to remove the component. This design effectively improves the problem of difficulty in removing the component after unlocking, and is especially suitable for scenarios where the component to be locked and the cavity fit tightly, improving the overall ease of operation. For example, even when the component to be locked fits tightly with the cavity, facilitating the insertion of the charging port, it still maintains better operational convenience. For instance, the pop-out mechanism can expose the handle of the component to be locked, making it easier for the user to grasp.

[0041] To provide a stable driving force for the movement of locking element 3, in one alternative solution, refer to Figure 1-5 As shown, the structure of the execution component 4 can also be designed as follows: the execution component 4 includes a motor component 41, and the output end of the motor component 41 is provided with a linkage component 42. The motor component 41 drives the locking component 3 to move through the linkage component 42.

[0042] The motor assembly 41 includes a DC motor and a reduction gear set. The input end of the reduction gear set is connected to the output shaft of the motor via gear meshing, and the output end (i.e., the output end of the motor assembly 41) is connected to and fixed to the linkage 42 via a key. The motor assembly 41 is fixed to the mounting base by a mounting plate, and the linkage 42 and the locking member 3 are connected by a slot or protrusion. When the locking member 3 needs to be moved, the motor is powered on and rotates. After the speed is reduced and the torque is increased by the reduction gear set, the linkage 42 is driven to rotate or move. The linkage 42 then drives the locking member 3 to move in a preset direction through the mating structure. The reduction gear set can improve the stability of the motor driving force, avoid the locking member 3 from moving too violently due to excessive motor speed, reduce component impact, and also improve the load capacity of the locking member 3, ensuring smooth operation even with slight jamming. In addition, the motor assembly 41 can be precisely controlled by a controller, which is convenient for integration with the overall control system of the equipment to realize automated locking and unlocking operations. It is suitable for scenarios such as shared battery cabinets that require remote or automatic control.

[0043] To make the engagement between the linkage 42 and the locking member 3 smoother and reduce motion interference, the following optimization method can be selected: the linkage 42 is a cam, and the locking member 3 is provided with a mating surface 32 at the position corresponding to the cam. The output end of the motor assembly 41 rotates to drive the cam to rotate and engage with the mating surface 32 to drive the locking member 3 to move.

[0044] The circumferential profile of the cam is designed according to the required stroke of the locking element 3. The mating surface 32 of the locking element 3 is an arc-shaped surface or a plane that matches the cam profile. The cam is fixed on the shaft at the output end of the motor assembly 41. The locking element 3 is restricted to moving only in a straight line by a guide structure, and the mating surface 32 contacts the circumferential surface of the cam for engagement. When the motor assembly 41 drives the cam to rotate, it pushes the locking element 3 to move in a straight line, thereby restricting or releasing the rotation of the locking hook 2. The cam transmission structure is simple and compact, requiring no complex linkage mechanism, which can effectively reduce the number of moving parts and reduce assembly difficulty.

[0045] In order to make the movement of the locking element 3 smoother and avoid sudden displacement that could cause impact on the mechanism, in some options, the structure of the cam can be improved as follows: the distance between the circumferential surface of the cam and the circumferential surface of the output end of the motor assembly 41 continuously increases or decreases along the rotation direction of the cam.

[0046] The circumferential surface of the cam features a rounded transition design, with a smooth curve from the minimum radius position to the maximum radius position, without obvious sharp angles or abrupt changes. When the motor assembly 41 drives the cam to rotate at a constant speed, the rate of change of the radius at the contact point between the cam's circumferential surface and the mating surface 32 remains stable, and the speed at which the locking element 3 moves also changes smoothly, without sudden acceleration or deceleration. This design can reduce noise during mechanism operation to a certain extent, while also preventing component loosening or damage due to impact, thus extending the service life of the mechanism.

[0047] To enable the locking element 3 to automatically reset after the execution component 4 stops driving, facilitating the next locking operation, the following optimization method can be selected: the execution component 4 also includes a reset spring 43 connected to the locking element 3; the motor component 41 drives the locking element 3 to move via a cam to release the restriction on the rotation of the lock hook 2, and the locking element 3 is driven by the reset spring 43 to move in the direction that restricts the rotation of the lock hook 2.

[0048] One end of the return spring 43 is pressed against the lug of the locking member 3, and the other end is pressed against the fixed post of the mounting base. When the motor assembly 41 drives the cam to rotate, pushing the locking member 3 to move in the direction of releasing the limit, the locking member 3 will compress the return spring 43, causing the spring to accumulate elastic potential energy. After the unlocking operation is completed, the motor assembly 41 drives the cam to rotate in the opposite direction, and the thrust of the cam on the locking member 3 gradually decreases. The return spring 43 begins to release elastic potential energy, providing thrust for the locking member 3 to move back to the initial position (i.e., the position that restricts the rotation of the locking hook 2).

[0049] In the scheme where the locking hook 2 restricts the movement of the locking member 3 at the aforementioned unlocking position, once the locking hook 2 rotates in the locking direction, the locking hook 2 will disengage from the locking member 3. At this time, under the action of the return spring 43, the locking member 3 will automatically move to restrict the rotation of the locking hook 2, thus achieving the function of "automatic locking" of the locking hook 2. In particular, the motor assembly 41 adopts a driving method in which the locking member 3 is driven to move and contact the locking hook 2 to restrict it before reversing and resetting.

[0050] In some special cases, such as when the actuator 4 fails to drive the locking member 3, in order to still enable the movement of the locking member 3, the following improvements can be made: a manual lever 6 is provided on the locking member 3. The manual lever 6 is used to manually move the locking member 3 in the direction that contacts and restricts the rotation of the locking hook 2.

[0051] The manual lever 6 is fixed to the locking element 3 by screws or inserted into the locking element 3 via a slot, and extends to a reserved opening in the equipment housing for easy access by the operator. When the motor assembly 41 or other actuators malfunction, the operator can insert a finger or tool through the opening to move the manual lever 6, causing the locking element 3 to move along the guide direction, releasing the restriction on the rotation of the locking hook 2, thereby unlocking the component to be locked. This emergency operation structure improves the fault tolerance of the mechanism, preventing the component to be locked from being unable to be removed for an extended period due to a malfunction of the actuator 4, reducing the impact of equipment downtime; at the same time, the manual lever 6 does not affect normal automatic operation, balancing automation and emergency needs.

[0052] In addition to using motor assembly 41 as actuating assembly 4, to adapt to different installation spaces and driving force requirements, in one optional scheme, refer to Figure 6 and 7 As shown, the following execution component 4 structure can also be selected. The execution component 4 includes an electromagnetic pull rod 44. The telescopic rod 441 of the electromagnetic pull rod 44 is linked with the locking member 3 to drive the locking member 3 to move.

[0053] The electromagnetic pull rod 44 is fixed to the mounting bracket with bolts, and the free end of its telescopic rod 441 is fixed to the connecting block of the locking element 3 via a threaded connection or pin. The power supply line of the electromagnetic pull rod 44 is connected to the control module of the equipment, and its power supply can be controlled by the control module. When it is necessary to drive the locking element 3, the control module energizes the electromagnetic pull rod 44, and the telescopic rod 441 extends or retracts under the action of electromagnetic force, directly driving the locking element 3 to move along the guide structure, thereby restricting or releasing the rotation of the locking hook 2. The electromagnetic pull rod 44 has a fast response speed, which can quickly drive the locking element 3 to move, reducing the response time of locking and unlocking and improving operating efficiency.

[0054] Furthermore, the electromagnetic pull rod 44 has an automatic reset spring. After power is cut off, the spring can automatically reset the telescopic rod 441. With the help of this reset action, it can cooperate with the aforementioned scheme of restricting the movement of the locking member 3 by the locking hook 2 in the unlocking position. Once the locking hook 2 rotates in the locking direction, the locking hook 2 will disengage from the locking member 3. At this time, under the action of the spring of the electromagnetic pull rod 44, the telescopic rod 441 will reset and move the locking member 3. The locking member 3 will restrict the rotation of the locking hook 2, thus achieving the function of "automatically locking" the locking hook 2. Especially with the drive method adopted by the motor assembly 41, which is to drive the locking member 3 to move and contact the locking hook 2, and then reverse (or continue to rotate in the same direction to reset the linkage 42) to reset.

[0055] To enable the telescopic rod 441 of the electromagnetic pull rod 44 to move the locking member 3 more flexibly and adapt to different transmission direction requirements, the following optimization method can be selected: the actuator 4 also includes a connecting member 45, which is rotatably connected around a fixed shaft, with one end hinged to the telescopic rod 441 and the other end connected to the locking member 3. The electromagnetic pull rod 44 drives the connecting member 45 to rotate through the telescopic movement of the telescopic rod 441, thereby driving the locking member 3 to move.

[0056] The fixed shaft is integrally formed at a preset position on the mounting base. The connecting piece 45 has a shaft hole adapted to the fixed shaft, and it is rotatably connected to the fixed shaft by fitting into the shaft hole. One end of the connecting piece 45 is hinged to the telescopic rod 441 of the electromagnetic pull rod 44, and the other end is rotatably connected by inserting into a notch on the locking piece 3. When the telescopic rod 441 of the electromagnetic pull rod 44 extends, it pushes the connecting piece 45 to rotate around the fixed shaft. During the rotation of the connecting piece 45, it pries the locking piece 3 to move. When the telescopic rod 441 retracts, it pulls the connecting piece 45 to rotate around the fixed shaft, thereby prying the locking piece 3 to move in the opposite direction. This transmission structure can change the direction of movement of the telescopic rod 441, so that the electromagnetic pull rod 44 does not need to be strictly aligned with the direction of movement of the locking piece 3. The installation angle and position of the electromagnetic pull rod 44 can be flexibly adjusted according to the internal space of the equipment, improving the flexibility of the mechanism layout.

[0057] In order to ensure that the telescopic rod 441 can still be manually operated in the event of a malfunction of the electromagnetic lever 44, and to ensure the movement of the locking element 3, in some options, the following improvements can be made: a manual lever 6 is provided on the telescopic rod 441, which is used to manually move the telescopic rod 441.

[0058] The manual lever 6 is fixed to the telescopic rod 441 of the electromagnetic pull rod 44 by welding or riveting. The length and shape of the lever are designed according to the operating space to ensure that the operator can access the lever through the operating port reserved in the equipment. When the electromagnetic pull rod 44 fails to drive the telescopic rod 441 due to power failure or internal malfunction, the operator can directly push or pull the telescopic rod 441 through the lever. During the movement of the telescopic rod 441, the connecting piece 45 rotates, which in turn moves the locking piece 3, releasing the restriction on the rotation of the locking hook 2. This design provides a reliable emergency unlocking method for the mechanism driven by the electromagnetic pull rod 44, avoiding the inability to remove the locked part due to the failure of the electromagnetic pull rod 44, and improving the availability of the mechanism in special situations. At the same time, the manual lever 6 has a simple structure, does not require additional complex parts, and has a low cost.

[0059] Based on the aforementioned locking mechanism, in order to apply it to battery charging scenarios and improve the stability of battery charging, this embodiment also provides a battery charging compartment, as described above. Figure 1 and 8As shown, it includes a storage compartment 7, a power interface 8 located inside the storage compartment 7, and any one of the above-mentioned locking mechanisms, which are used to lock or unlock the battery placed in the storage compartment 7.

[0060] The storage compartment 7 is a rectangular cavity structure with its opening facing outwards for easy battery insertion; the power interface 8 is connected to an external power source via a wire and is fixed to the bottom of the cavity of the storage compartment 7, with the interface position corresponding to the battery charging interface position; the mounting base of the locking mechanism is fixed to the inner walls of both sides of the storage compartment 7 by bolts, and the position of the locking hook 2 corresponds to the locking position on the side after the battery is inserted. When the user inserts the battery into the opening of the receiving compartment 7, the battery slides along the inner wall of the receiving compartment 7 until the charging interface at the bottom of the battery aligns with the power interface 8 inside the receiving compartment 7. At this time, external force drives the locking hook 2 to overcome the unlocking tendency of the elastic element 21 and rotate to the position where it is locked into the side locking groove of the battery. The execution component 4 (specifically, the aforementioned reset spring 43) drives the locking element 3 to move, restricting the rotation of the locking hook 2 and keeping the battery in the docked state with the power interface 8. This reduces the loosening of the battery due to vibration or slight collision during charging, improves the stability of charging, and reduces the probability of charging interruption. When the user needs to remove the battery, the unlocking command is triggered through the device's interaction module. The execution component 4 drives the locking element 3 to release the restriction on the locking hook 2. The elastic element 21 drives the locking hook 2 to automatically rotate in the unlocking direction, disengaging it from the locked position of the battery. If a pop-out component 5 is provided, the pop-out component 5 will push the battery towards the opening, making it convenient for the user to remove the battery.

[0061] To enable shared use of batteries, the aforementioned battery charging compartment is integrated into the cabinet structure. In one alternative solution, a shared battery cabinet is also provided, including the aforementioned battery charging compartment.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
