Description

Technical Field

[0001] This application relates to the field of shared power bank technology, and in particular to a power bank rental device. Background Technology

[0002] With the increasing prevalence of shared power banks in people's daily lives, power bank rental devices are suitable for various public places such as shopping malls, train stations, airports, and hotels, providing users with convenient charging services. Power bank rental devices are intelligent, convenient, and safe charging equipment that supports returning power banks in different locations, effectively solving the problem of charging difficulties for users when they are out and about, and have broad application prospects.

[0003] Existing power bank rental equipment typically adopts an integrated structure with a fixed number of compartments and a fixed number of built-in power banks. In locations with high demand for power banks, the number of rental devices needs to be increased to address this issue, which increases management costs. Conversely, in locations with low demand, having too many built-in power banks in the rental devices leads to resource waste and increases production costs. Utility Model Content

[0004] In view of this, it is necessary to provide a power bank rental device that can solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0007] The host includes a power module, which is electrically connected to an external power supply and is used to convert the input voltage of the external power supply into the device voltage.

[0008] The charging case body is detachably connected to the host. The charging case body includes multiple charging case modules, which are independent of each other and arranged in a stacked manner. Among the multiple charging case modules, two adjacent charging case modules are detachably connected.

[0009] Each of the charging compartment modules includes a power cord, and multiple power cords are electrically connected to the power module in parallel so that the input voltage of each power cord is equal to the voltage of the device.

[0010] In one embodiment, the host further includes a main control board, which is electrically connected to the power module and the power cord, so that the power module can provide the device voltage to the main control board.

[0011] Each charging case module further includes a slave control board and multiple compartments. One end of the power line away from the main control board is electrically connected to the slave control board, so that the main control board can provide the device voltage to the slave control board through the power line. The multiple compartments are electrically connected to the slave control board in parallel, wherein each compartment is used to hold a power bank, so that the slave control board can supply power to the power bank located in the compartment.

[0012] In one embodiment, a snap-fit ​​part is formed between a charging compartment module adjacent to the host on the charging compartment body and the host, and the charging compartment module and the host can be snap-fitted together through the snap-fit ​​part;

[0013] The snap-fit ​​part is located inside the charging compartment module and the host.

[0014] In one embodiment, a snap-fit ​​engagement portion is formed between two adjacent charging compartment modules, and the two adjacent charging compartment modules can be snap-fitted together through the snap-fit ​​engagement portion.

[0015] The snap-fit ​​part is located inside the main body of the charging compartment.

[0016] In one embodiment, one of the two adjacent charging case modules includes a first housing and the other includes a second housing. The first housing is provided with an extension protrusion that can be inserted into the second housing and engage with it.

[0017] In one embodiment, a limiting rib is provided inside the second housing;

[0018] When the extended protrusion is inserted into the second housing, the limiting rib can abut against the extended protrusion to limit the assembly of the first housing and the second housing.

[0019] In one embodiment, the charging case module includes multiple compartments, each compartment having a stepped surface; and the power bank can conform to the stepped surface and move relative to the compartment.

[0020] The first housing has multiple inlets and outlets, each of which corresponds to a different compartment. The power bank can extend from or enter the corresponding compartment through the corresponding inlet or outlet.

[0021] The step surface is set higher than or flush with the bottom surface of the inlet / outlet along the vertical direction of the insertion of the power bank into the compartment.

[0022] In one embodiment, the charging case module includes two rows of compartments, each of which can hold a power bank;

[0023] The power bank rental device also includes multiple motor locks, which are arranged sequentially and at intervals between the two rows of compartments and connected to the main body of the charging compartment. Each motor lock can control the locking / unlocking of two power banks arranged side by side in the two rows of compartments within the corresponding compartment.

[0024] In one embodiment, the motor lock includes:

[0025] Electric motor;

[0026] A turntable assembly is connected to the motor drive. The turntable assembly includes a first turntable and a second turntable. The second turntable is fitted onto the first turntable in a circumferentially limited manner and is slidably connected to the first turntable.

[0029] In one embodiment, the second turntable is provided with two push blocks, which are arranged on the upper and lower sides of the second turntable and correspond one-to-one with the two locking elements.

[0030] In the motor operating state, one of the push blocks can drive the second turntable to slide on the first turntable under the pushing of the corresponding locking element, so that the slid second turntable can be unlocked by the other push block pushing against the other locking element.

[0031] Due to the application of the above solution, this application has the following advantages compared with the prior art:

[0032] The power bank rental device claimed in this application features a modular design, allowing each charging compartment module to be manufactured separately. This enables the power bank rental device to select the number of charging compartment modules according to usage needs, reducing management and cost expenses when dealing with varying numbers of power banks. Simultaneously, the power supply voltage to multiple charging compartment modules is converted using an internal power module, allowing each module to receive the converted voltage as its operating voltage. This eliminates the need for a separate power module within each charging compartment module, further reducing manufacturing costs. Furthermore, the design eliminates the need to consider the assembly space of a power module, allowing for a smaller charging compartment module design. Attached Figure Description

[0055] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0060] like Figures 1 to 7 , Figure 11 , Figure 20As shown, an embodiment of this application provides a power bank rental device 1, which includes a main unit 200 and a charging compartment body 300. The main unit 200 includes a power module 210, which is electrically connected to an external power source (not shown) and is used to convert the input voltage of the external power source into the device voltage. The charging compartment body 300 is detachably connected to the main unit 200. The charging compartment body 300 includes multiple charging compartment modules 310, which are independent of each other and arranged in a stacked manner. Two adjacent charging compartment modules 310 are detachably connected. Each charging compartment module 310 includes a power cord (not shown), and multiple power cords are electrically connected to the power module 210 in parallel so that the input voltage of each power cord is equal to the device voltage. It should be noted that each charging compartment module 310 in this application contains 6 built-in power banks 500. The power bank rental device 1 can select the number of charging compartment modules 310 according to usage needs and stack multiple charging compartment modules 310, so that the number of built-in power banks 500 in the power bank rental device 1 can be 12, 18 or even other multiples of 6. It is understood that in other embodiments, the number of built-in power banks 500 in each charging compartment module 310 can also be 4, 8, etc., which will not be elaborated here.

[0061] It is understood that this application enables a modular design for the power bank rental device 1, allowing the charging compartment module 310 to be manufactured independently. This allows the power bank rental device 1 to select the number of charging compartment modules 310 according to usage requirements, thus reducing management and cost expenses when dealing with different numbers of power banks 500. Simultaneously, a single power module 210 within the main unit 200 converts the supply voltage to multiple charging compartment modules 310. Each charging compartment module 310 can receive the device voltage converted by the power module 210 as its operating voltage, eliminating the need to install a power module 210 within each charging compartment module 310. This further reduces the manufacturing cost of the charging compartment module 310. Furthermore, the design of the charging compartment module 310 does not require consideration of the assembly space for the power module 210, allowing for a smaller design. Here, the aforementioned power module 210 can specifically be an adapter for voltage conversion.

[0062] like Figure 3 , Figure 5 , Figure 11As shown, in one embodiment, the host 200 further includes a main control board 220, which is electrically connected to the power module 210 and the power cord, so that the power module 210 can provide device voltage to the main control board 220; each charging compartment module 310 further includes a slave control board 314 and multiple compartments 313, with one end of the power cord away from the main control board 220 electrically connected to the slave control board 314, so that the main control board 220 can provide device voltage to the slave control board 314 through the power cord; the multiple compartments 313 are electrically connected to the slave control board 314 in parallel, wherein each compartment 313 is used to house a power bank 500, so that the slave control board 314 can supply power to the power bank 500 located in the compartment 313. In other words, the power bank rental device 1 in this embodiment has only one power module 210 to enable the main unit 200 and multiple charging compartment modules 310 to operate under the device voltage. This avoids configuring a power module 210 for voltage conversion in each charging compartment module 310, thus reducing costs. Moreover, the power bank rental device 1 can operate without disconnecting its external power supply when disassembling the charging compartment module 310. This not only prevents accidents caused by improper disassembly operations but also allows the power bank rental device 1 to continue operating normally while the charging compartment module 310 is being disassembled. Here, the main control board 220 and the power module 210 can be electrically connected using quick-connect connectors, and each power cable can also be electrically connected to the main control board 220 and the corresponding slave control board 314 using quick-connect connectors.

[0063] like Figure 20 As shown, in one embodiment, the power line for the electrical connection between the slave control board 314 and the main control board 220 in each charging compartment module 310 includes a power transmission line and a signal transmission line. The main control board 220 can supply power to the slave control board 314 using the power transmission line, and the signal transmission line is used for signal transmission between the slave control board 314 and the main control board 220, so as to achieve the purpose of the main control board 220 controlling the slave control board 314 and controlling the operation of the charging compartment module 310. It should be noted that the working principle of how the main control board 220 controls the operation of the slave control board 314 through the signal transmission line can adopt existing conventional methods, which will not be elaborated here.

[0064] For example, when there is one charging case module 310, the main control board 220 in the host 200 can supply power to the slave control board 314 in the charging case module 310 and control the operation of the slave control board 314; when there are two, three or more charging case modules 310, the main control board 220 in the host 200 can supply power to the slave control board 314 in the charging case module 310 respectively and control the operation of the slave control board 314.

[0065] like Figure 4 As shown, in one embodiment, a snap-fit ​​mating portion is formed between two adjacent charging compartment modules 310, and the two adjacent charging compartment modules 310 can be snap-fitted together through the snap-fit ​​mating portion; wherein, the snap-fit ​​mating portion is disposed inside the charging compartment body 300. It can be understood that since the snap-fit ​​mating portion when the two adjacent charging compartment modules 310 are snapped together is located inside the charging compartment body 300, the snap-fit ​​mating portion can be hidden, and the overall aesthetics of the charging compartment body 300 can be ensured. Here, the snap-fit ​​mating portion includes a hook 3122 and a slot plate 3112, which snap-fit ​​together to realize the assembly connection between the two adjacent charging compartment modules 310.

[0066] like Figure 6 As shown, in one embodiment, there are four snap-fit ​​parts, which are arranged on two opposite sides of the charging compartment body 300 to improve the stability when two adjacent charging compartment modules 310 are snapped together.

[0067] like Figure 6 , Figure 7 As shown, in one embodiment, one of two adjacent charging compartment modules 310 includes a first housing 311 and the other includes a second housing 312. The first housing 311 has an extending protrusion 3111 that can be inserted into the second housing 312, allowing the first housing 311 and the second housing 312 to engage. It can be understood that the insertion and engagement between the extending protrusion 3111 on the first housing 311 and the second housing 312 guides the assembly of the first housing 311 and the second housing 312, ensuring that the two housings can engage during assembly. Here, a slot plate 3112 is formed at the upper end of the first housing 311, and a hook 3122 is formed at the lower end of the second housing 312.

[0068] It should be noted that in order to allow three, four, or even more charging compartment modules 310 to be stacked, each charging compartment module 310 can have a slot plate 3112 formed at the upper end and a hook 3122 formed at the lower end in the height direction of the charging compartment module 310.

[0069] like Figure 6 , Figure 7As shown, in one embodiment, a limiting rib 3121 is provided inside the second housing 312. When the extending protrusion 3111 is inserted into the second housing 312, the limiting rib 3121 can abut against the extending protrusion 3111 to limit the assembly of the first housing 311 and the second housing 312. It can be understood that the structural arrangement of the limiting rib 3121 can ensure the accuracy of the position of the second housing 312 when it is assembled on the first housing 311. At the same time, since the limiting rib 3121 can abut against the extending protrusion 3111, the first housing 311 can also support the second housing 312 through the limiting rib 3121, thereby improving the stability and reliability of the first housing 311 supporting the second housing 312. Here, multiple limiting ribs 3121 are formed on the inner sidewall of the second housing 312, and each limiting rib 3121 can abut against the extending protrusion 3111.

[0070] like Figure 6 , Figure 7 As shown, in one embodiment, a guide engagement portion 3113 is formed on the extension protrusion 3111 of the first housing 311. The guide engagement portion 3113 is used to guide the insertion engagement between the extension protrusion 3111 and the second housing 312. This facilitates the insertion engagement between the first housing 311 and the second housing 312 and ensures that the first housing 311 and the second housing 312 can be snapped together after assembly.

[0071] like Figure 8 , Figure 9 As shown, in one embodiment, a stepped surface 3131 is formed on the compartment 313; and the power bank 500 can move relative to the compartment 313 by conforming to the stepped surface 3131; the first housing 311 has multiple inlets and outlets 3115, each corresponding to a different compartment 313, and the power bank 500 can extend out of or into the corresponding compartment 313 from the corresponding inlet and outlet 3115; along the vertical direction of the power bank 500 being inserted into the compartment 313, the stepped surface 3131 is set higher than or flush with the bottom surface 3116 of the inlet and outlet 3115. This arrangement prevents interference between the protruding wire harness (not shown) on the power bank 500 and the first housing 311 when the power bank 500 extends out of the compartment 313, thus avoiding the power bank 500 extending too short a distance or getting stuck when it extends out of the compartment 313.

[0072] like Figure 1 , Figure 2As shown, in one embodiment, the charging case body 300 further includes a plurality of first connectors 320, and two adjacent charging case modules 310 are detachably connected by the plurality of first connectors 320; wherein, the plurality of first connectors 320 are arranged on two opposite sides of the charging case body 300. It can be understood that, in addition to the snap-fit ​​connection between two adjacent charging case modules 310, the first connectors 320 arranged on two opposite sides of the charging case body 300 are used to connect the two adjacent charging case modules 310, thereby improving the connection stability when connecting two adjacent charging case modules 310. Here, the number of first connectors 320 is two; of course, in other embodiments, the number of first connectors 320 can be configured to be four, six, or even more.

[0073] Preferably, such as Figure 6 As shown, a connecting seat 3114 is formed on the first housing 311. Specifically, the first housing 311 and the second housing 312 can be screwed together by a first connecting member 320 passing through the second housing 312 and the connecting seat 3114. The first connecting member 320 is used to press and limit the second housing 312 onto the first housing 311, thereby realizing the screwed connection between the first housing 311 and the second housing 312. Here, the first connecting member 320 can be set as a self-tapping screw, bolt, etc.

[0074] like Figure 3 As shown, in one embodiment, a snap-fit ​​portion is formed between a charging compartment module 310 adjacent to the host 200 on the charging compartment body 300 and the host 200, and the charging compartment module 310 and the host 200 can be snap-fitted together through the snap-fit ​​portion; wherein, the snap-fit ​​portion is disposed inside the charging compartment module 310 and the host 200. This allows the snap-fit ​​portion to be hidden and ensures the overall aesthetics of the charging compartment body 300. It should be noted that the specific snap-fitting mechanism between the host 200 and the charging compartment module 310 adjacent to the host 200 on the charging compartment body 300 can be referred to the snap-fitting mechanism between two adjacent charging compartment modules 310 described above, and will not be repeated here.

[0075] like Figure 1 , Figure 2As shown, in one embodiment, the power bank rental device 1 further includes a base 400, which is disposed at the bottom of the charging compartment body 300 to support the charging compartment body 300. A charging compartment module 310 adjacent to the base 400 on the charging compartment body 300 is detachably connected to the base 400. It should be noted that the specific detachable connection between the charging compartment module 310 adjacent to the base 400 on the charging compartment body 300 and the base 400 can be referred to the connection method between two adjacent charging compartment modules 310 described above, and will not be repeated here.

[0076] like Figure 10 , Figure 11 As shown, in one embodiment, multiple compartments 313 are arranged in two rows, and each compartment 313 in both rows can accommodate one power bank 500. The power bank rental device 1 also includes multiple motor locks 100, which are sequentially and spaced apart between the two rows of compartments 313 and connected to the charging compartment body 300. Each motor lock 100 can control the locking / unlocking of two power banks 500 side by side in the two rows of compartments 313 within the corresponding compartment 313. It can be understood that when the charging compartment module 310 is working, one motor lock 100 can unlock / lock two power banks 500 side by side in the two rows of compartments within the charging compartment module 310. In this way, the number of motor locks 100 required for the charging compartment module 310 can be reduced, which can further reduce the overall production cost of the charging compartment module 310, and on the other hand, it can also reduce the overall volume of the charging compartment module 310.

[0077] like Figure 10 As shown, in one embodiment, the motor lock 100 includes a housing 10. The motor lock 100 is mounted on the housing 10 and is screwed to the charging compartment body 300 by bolts 600 passing through the housing 10, thereby realizing the assembly connection between the motor lock 100 and the charging compartment body 300.

[0078] like Figures 12 to 16As shown, in one embodiment, the motor lock 100 includes a motor 30, a turntable assembly 40, and a locking assembly. The turntable assembly 40 is drivenly connected to the motor 30. The turntable assembly 40 includes a first turntable 41 and a second turntable 42. The second turntable 42 is mounted on the first turntable 41 in a circumferentially limited manner and is slidably connected to the first turntable 41. The locking assembly includes two locking elements 21, which are slidably arranged on two opposite sides of the first turntable 41. Each locking element 21 can move between a locked position and an unlocked position, and each locking element 21 can move from the locked position to the unlocked position under the drive of the slidable second turntable 42. The motor 30 has a stopped state and a working state. In the stopped state, both locking elements 21 are in the locked position. In the working state, one of the two locking elements 21 is in the locked position and the other is in the unlocked position. It can be understood that the motor lock 100 controls the two locking elements 21 to unlock alternately by rotating the motor shaft 31 on the motor 30 in both directions. This allows the motor lock 100 to control the unlocking / locking of the two power banks 500 inside the charging compartment body 300 using only one motor 30. Here, each locking element 21 can move between the locked and unlocked positions. Specifically, each locking element 21 can slide a preset distance along the centerline of the housing 10.

[0079] Specifically, such as Figure 12 As shown, the housing 10 includes a first housing 11 and a second housing 12. Specifically, the first housing 11 and the second housing 12 can be connected by a threaded connection between the first housing 11 and the second housing 12 using self-tapping screws, bolts, or other connecting parts 50 passing through the first housing 11. Here, the locking element 21 also includes a sliding plate 213. Each locking element 21 can slide against the first housing 11 and the second housing 12 via the sliding plate 213, thereby achieving a sliding assembly of each locking element 21 with and on the housing 10.

[0080] like Figure 15 , Figure 16 As shown, in one embodiment, the second turntable 42 is provided with a groove 422, and the outer peripheral surface of the first turntable 41 is provided with a rib 412. The rib 412 is provided corresponding to the groove 422, and the rib 412 can be inserted into the corresponding groove 422 to limit the second turntable 42 circumferentially on the first turntable 41. The second turntable 42 can slide relative to the first turntable 41 along the length direction of the rib 412.

[0081] like Figures 14 to 16As shown, in one embodiment, a first groove 411 is provided on the inner side of the first turntable 41, and a first rib 301 is provided on the outer peripheral surface of the motor shaft 31. The first rib 301 is correspondingly provided with the first groove 411, and the first rib 301 can be inserted and engaged with the corresponding first groove 411 to limit the first turntable 41 circumferentially on the motor 30, so that the first turntable 41 can rotate with the motor shaft 31 of the motor 30.

[0082] like Figure 15 , Figure 17 As shown, in one embodiment, the second turntable 42 is provided with two push blocks 421. The two push blocks 421 are arranged on the upper and lower sides of the second turntable 42 and correspond one-to-one with the two locking elements 21. When the motor 30 is working, one of the push blocks 421 can drive the second turntable 42 to slide on the first turntable 41 under the pushing of the corresponding locking element 21, so that the slid second turntable 42 can be unlocked by the other push block 421 pushing against the other locking element 21.

[0083] like Figure 15 , Figure 17 As shown, in one embodiment, the push block 421 located below the second turntable 42 is designated as the first push block 4213, and the locking element 21 that can be unlocked under the drive of the first push block 4213 is designated as the second locking element 214. A push mating block 2141 is formed on the second locking element 214, and the second locking element 214 can abut against the first push block 4213 through the push mating block 2141. The push mating block 2141 is provided with a clearance groove 21411, which is used to avoid the first push block 4213 so that the first push block 4213 can rotate relative to the push mating block 2141 through the clearance groove 21411. It should be noted that, since the pushing block 2141 slides linearly within the housing 10, and the first pushing block 4213 rotates within the housing 10, the first pushing block 4213 will gradually misalign with the pushing block 2141 during the pushing process until they are completely disengaged. Here, the pushing block 421 located above the second turntable 42 is designated as the second pushing block 4214, and the locking element 21 that can be unlocked under the drive of the second pushing block 4214 is designated as the first locking element 215.

[0084] Furthermore, if Figure 15 , Figure 18As shown, one end face of the second push block 4214 is configured as a second push slope 42141. When the second turntable 42 rotates clockwise, the second push block 4214 can abut against the first locking element 215 through the second push slope 42141. In this way, the second push block 4214 can drive the second turntable 42 to slide downward on the first turntable 41 under the pushing of the first locking element 215. Correspondingly, one end face of the first push block 4213 is configured as a first push plane 42132, so that the slidable second turntable 42 can abut against the second locking element 214 through the first push plane 42132, which is used to drive the second locking element 214 to unlock.

[0085] Furthermore, such as Figure 15 As shown, the other end face of the first push block 4213 is configured as a first push slope 42131. When the second turntable rotates counterclockwise, the first push block 4213 can abut against the second locking element 214 through the first push slope 42131. In this way, the first push block 4213 can drive the second turntable 42 to slide upward on the first turntable 41 under the push of the first push slope 42131. Correspondingly, the other end face of the second push block 4214 is configured as a second push plane 42142, so that the slid second turntable 42 can abut against the first locking element 215 through the second push plane 42142, which is used to drive the first locking element 215 to unlock.

[0086] like Figure 13 , Figure 19 As shown, in one embodiment, the locking assembly further includes a spring 22, which is pre-compressed and mounted between the two locking elements 21. Utilizing the elastic deformation of the spring 22, the two locking elements 21 can automatically extend from the housing 10 without being pushed by the second turntable 42, thus meeting the need to lock the power bank 500 using the locking elements 21. In other words, when the motor lock 100 is working, the motor 30 can control the second turntable 42 to rotate within the housing 10, and then use the push block 421 on the second turntable 42 and the spring 22 to push against the corresponding locking elements 21, thereby controlling the sliding of each locking element 21 back and forth on the housing 10, and achieving control over the unlocking / locking of the corresponding power bank 500 by each locking element 21.

[0087] like Figure 13As shown, in one embodiment, a first limiting portion 211 is formed on the first locking element 215, and a second limiting portion 212 is formed on the second locking element 214. The first limiting portion 211 and the second limiting portion 212 can be inserted and engaged with the spring 22 to limit the spring 22. This facilitates the assembly of the spring 22 between the two locking elements 21 and ensures the stability of the spring 22 when assembled between the two locking elements 21. Here, both the first limiting portion 211 and the second limiting portion 212 are configured as positioning protrusions that can be inserted into both ends of the spring 22.

[0088] The working principle of the motor lock 100 in this application for unlocking / locking two power banks 500 arranged side by side in the two rows of compartments 313 within the charging compartment module 310 is as follows: Figure 17 In the initial position of the motor lock 100, when the motor shaft 31 of the motor 30 rotates clockwise, the motor shaft 31 drives the second turntable 42 to rotate within the housing 10 via the first turntable 41. During this process, the second pushing slope 42141 of the second pushing block 4214 on the second turntable 42 first abuts against the third pushing slope 2151 on the first locking element 215. As the second turntable 42 continues to rotate, the action and reaction forces allow the second turntable 42 to slide downwards on the first turntable 41 until the second pushing slope 42141 of the second pushing block 4214 disengages from the third pushing slope 2151 on the first locking element 215. Specifically, it can be as follows: Figure 18 As shown, the second turntable 42 stops sliding. Afterwards, the second turntable 42 continues to rotate. The first pushing surface 42132 on the first pushing block 4213 can push against the pushing engagement block 2141 of the second locking element 214. Under the pushing of the pushing engagement block 2141, the second locking element 214 can compress the spring 22 and unlock. Specifically, as shown... Figure 19 As shown, simultaneously, the locking tongue 2143 on the second locking element 214 disengages from the slot 501 of the power bank 500, specifically as follows: Figure 11As shown, the second locking element 214 can thus release the lock on the power bank 500. When the second turntable 42 continues to rotate, the first pushing surface 42132 will disengage from the pushing engagement block 2141 and lose its pushing force on the second locking element 214, allowing the second locking element 214 to reset under the elastic pushing force of the spring 22. When the motor shaft 31 of the motor 30 rotates in the reverse direction (counterclockwise), the motor shaft 31 of the motor 30 drives the second turntable 42 to rotate on the housing 10 through the first turntable 41. During this process, the first pushing inclined surface 42131 of the first pushing block 4213 on the second turntable 42 first abuts against the fourth pushing inclined surface 2142 on the second locking element 214. As the second turntable 42 continues to rotate, the action and reaction forces can be used to lock the second turntable 42 in the first rotation. The second turntable 42 slides upward on the disk 41 until the first pushing slope 42131 of the first pushing block 4213 disengages from the fourth pushing slope 2142 of the second locking element 214. The second turntable 42 stops sliding. Then, the second turntable 42 continues to rotate. The second pushing plane 42142 on the second pushing block 4214 can push against the pushing part 2152 of the first locking element 215. Under the push of the pushing part 2152, the first locking element 215 can compress the spring 22 and unlock. In this way, the first locking element 215 can release the lock on the power bank 500. When the second turntable 42 continues to rotate, the second pushing plane 42142 will disengage from the pushing part 2152 and lose the push against the first locking element 215, so that the first locking element 215 will be reset under the elastic push of the spring 22.
