[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0044] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0046] This invention discloses a charging dock 10, with reference to Figures 1-4 As shown, the charging dock 10 includes a base 100, multiple elastic positioning members 200, a movable member 300, and a drive assembly 400. The base 100 is provided with a receiving groove 111 for accommodating multiple energy storage power sources 20. Each elastic positioning member 200 is mounted on the base 100. The movable member 300 is movably mounted on the base 100 and has multiple mating parts 310, which are arranged one-to-one with the multiple elastic positioning members 200. The drive assembly 400 is mounted in the mounting hole 121. One end of the drive assembly 400 is in transmission engagement with the movable member 300. The drive assembly 400 can drive the movable member 300 to move along a first direction. The mating parts 310 press against the elastic positioning members 200 so that the multiple elastic positioning members 200 can move one-to-one with each other along a second direction to approach and engage with the energy storage power sources 20, thereby locking the multiple energy storage power sources 20 in the receiving groove 111.

[0047] Understandably, since multiple energy storage power sources 20 are installed in the same receiving slot 111, the base 100 is provided with multiple elastic positioning elements 200 to lock or unlock the multiple energy storage power sources 20. In actual operation, the key 30 is engaged with the drive assembly 400, and the key 30 is rotated in the locking direction. During the rotation of the drive assembly 400, the movable part 300 can move in the first direction. During the movement of the movable part 300 in the first direction, it can squeeze the multiple elastic positioning elements 200, causing them to move one by one in the second direction to approach and engage the energy storage power sources 20. Locked within the receiving slot 111, the energy storage power supply 20 cannot be pulled out of the charging base 10 along its height direction. The key 30 is engaged with the drive assembly 400, and the key 30 is turned in the unlocking direction. The drive assembly 400 rotates in the reverse direction, causing the movable part 300 to move in the reverse direction. During this reverse movement, the movable part 300 releases the pressure on the elastic positioning member 200, causing it to spring back and disengage from the energy storage power supply 20 in the second direction, thus unlocking the energy storage power supply 20. At this point, the energy storage power supply 20 can be pulled out of the charging base 10 along its height direction. Therefore, through the cooperation of multiple elastic positioning members 200 and the movable part 300, multiple energy storage power supplies 20 can be unlocked or locked simultaneously while the key 30 is turning the drive assembly 400, allowing users to easily remove or replace multiple energy storage power supplies 20 at once, improving user satisfaction.

[0048] It should be noted that in this embodiment, the unlocking direction is counterclockwise and the locking direction is clockwise. Of course, in an alternative embodiment of the invention, the unlocking direction can be clockwise and the locking direction counterclockwise.

[0049] refer to Figures 5-6As shown, the base 100 has a through hole 112, which communicates with the receiving groove 111. The elastic positioning member 200 includes an elastic body 210 and a protrusion 220. The elastic body 210 is installed on the base 100 and can cooperate with the mating part 310. The protrusion 220 is integrally formed with the elastic body 210, passes through the through hole 112, and can be inserted into the receiving groove 111. It can be understood that during the locking process, after the key 30 is inserted into the driving part 411 of the driving assembly 400, the key 30 is rotated in the locking direction. The driving assembly 400 can rotate under the drive of the key 30 to push the movable member 300 to move in the first direction. During the movement of the movable member 300 in the first direction, the mating part 310 on the movable member 300 can compress the elastic body 210. The elastic body 210 transmits pressure to the protrusion 220, causing the protrusion 220 to move in the second direction and approach and engage with the energy storage power supply 20. The energy storage power supply 20 is locked. During the unlocking process, after inserting the key 30 into the drive part 411 of the drive assembly 400, the key 30 is rotated in the unlocking direction. The drive assembly 400 can rotate under the drive of the key 30 to push the movable part 300 to move in the opposite direction in the first direction. During the reverse movement of the movable part 300 in the first direction, the pressure of the mating part 310 on the elastic body 210 disappears, and the elastic body 210 automatically rebounds to drive the protrusion 220 to disengage from the energy storage power supply 20, thereby releasing the energy storage power supply 20. The locking and releasing of the energy storage power supply 20 is achieved by the elastic force of the elastic body 210 itself, without the need to add an additional spring or other movable parts 300, which simplifies the structure of the entire elastic positioning part 200 and the movable part 300 and helps to reduce manufacturing costs.

[0050] Optionally, the protrusion 220 and the elastomer 210 are welded together, and the two ends of the elastomer 210 are connected to the two ends of the through hole 112 by heat fusion. In this way, the strength of the elastic positioning member 200 and the connection strength between the entire elastic positioning member 200 and the base 100 can be ensured, thereby indirectly ensuring that the elastic positioning member 200 locks or releases the energy storage power supply 20.

[0051] Optionally, the elastomer 210 may be made of a material with good elasticity, such as rubber, depending on the actual needs.

[0052] refer to Figures 7-10As shown, the mating part 310 includes a first groove 311 and a second groove 312. The first groove 311 is disposed through the movable member 300. The groove walls of the second groove 312 are both arranged along the first direction with a driving inclined surface 3121 and a supporting plane 3122. The side of the driving inclined surface 3121 near the first groove 311 is lower than the side of the driving inclined surface 3121 near the supporting plane 3122. Understandably, during the actual working process, during the locking process, as the moving part 300 moves in the first direction, the second groove 312 of the mating part 310 gradually engages with the elastic body 210. Since the side of the driving inclined surface 3121 near the first groove 311 is lower than the side of the driving inclined surface 3121 near the supporting plane 3122, the elastic body 210 is gradually squeezed by the driving inclined surface 3121. Thus, the elastic body 210 transmits pressure to the protrusion 220, causing the protrusion 220 to move in the second direction and approach and engage with the energy storage power supply 20 to lock the energy storage power supply 20. When the supporting plane 3122 engages with the elastic body 210, it can resist the elastic body 210 so that it cannot rebound, thereby stably locking the energy storage power supply 20 in the base 100. Conversely, during the unlocking process, as the movable part 300 moves in the opposite direction in the first direction, the second groove 312 of the mating part 310 gradually disengages from the elastic body 210, and the driving inclined surface 3121 gradually disengages from the elastic body 210. When the movable part 300 moves to the position corresponding to the first groove 311 and the elastic body 210, the elastic body 210 is no longer compressed and automatically rebounds to drive the protrusion 220 to disengage from the energy storage power supply 20, thereby releasing the energy storage power supply 20. Thus, by providing space for the elastic body 210 to rebound through the through-hole first groove 311, by compressing the elastic body 210 through the driving inclined surface 3121, and by abutting the elastic body 210 with the supporting plane 3122, it is possible to ensure that the elastic positioning part 200 stably locks the energy storage power supply 20 and facilitates the release of the energy storage power supply 200 by the elastic positioning part 200. It should be noted that in other embodiments of the present invention, the mating part 310 may also include only a protrusion with a ramp. When the protrusion compresses the elastomer 210, it can lock the energy storage power supply 20. When the protrusion disengages from the elastomer 210, the energy storage power supply 20 is released.

[0053] refer to Figures 10-11As shown, the base 100 also includes a mounting hole 121. The drive assembly 400 is rotatably mounted in the mounting hole 121. A movable rack 320 is provided on the movable member 300 in the area corresponding to the mounting hole 121. A drive gear 412 is provided at the end of the drive assembly 400 away from the drive part 411. The drive gear 412 meshes with the movable rack 320. It can be understood that when the key 30 engages with the drive part 411 and rotates, the drive gear 412 can rotate. During the rotation of the drive gear 412, the movable rack 320 can be driven to move in the first direction. The meshing structure of the drive gear 412 and the movable rack 320 can facilitate the driving of the movable member 300. Of course, in other embodiments of the present invention, the driving structure of the movable member 300 and the drive assembly 400 can also be selected in other forms. For example, the drive assembly 400 is provided with a cam, and the movable member 300 is provided with a movable rod that abuts against the cam.

[0054] Optional, see reference Figures 10-11 As shown, the drive assembly 400 includes a first locking member 410 and a second locking member 420. One end of the first locking member 410 has a driving part 411, and the other end has a driving gear 412. The second locking member 420 is sleeved on the other end of the first locking member 410 and fixed to the mounting hole 121. It is understood that fixing the second locking member 420 within the mounting hole 121 ensures stable rotation of the first locking member 410. Furthermore, the fixed connection between the second locking member 420 and the mounting hole 121 improves the sealing performance between the drive assembly 400 and the mounting hole 121, reducing the entry of external contaminants into the base 100 through the gap between the drive assembly 400 and the mounting hole 121.

[0055] Further optional, see reference Figures 13-14As shown, the second locking member 420 is provided with a limiting protrusion 421, and the first locking member 410 is provided with a limiting groove 413. The limiting protrusion 421 cooperates with the limiting groove 413 to limit the rotation angle of the first locking member 410. It can be understood that during the locking process of the energy storage power supply 20, if the rotation angle of the first locking member 410 is too large, on the one hand, the drive gear 412 and the movable rack 320 may disengage, thereby preventing the drive assembly 400 from driving the movable member 300 to move. On the other hand, the mating part 310 on the movable member 300 may be misaligned with the elastic positioning member 200, preventing the elastic positioning member 200 from locking the energy storage power supply 20. In this embodiment, the second locking member 420 is provided with a limiting protrusion 421, and the first locking member 410 is provided with a limiting groove 413. With the limiting groove 413, during the locking of the energy storage power supply 20, when the first locking member 410 rotates, it cannot continue to rotate when the limiting protrusion 421 abuts against the side wall of the limiting groove 413. This limits the rotation angle of the first locking member 410, thus preventing the drive gear 412 and the movable rack 320 from disengaging, which would prevent the drive assembly 400 from driving the movable member 300. It also ensures that the elastic positioning member 200 and the mating part 310 are stably abutted, reliably locking the energy storage power supply 20. Of course, in other embodiments of the present invention, the limiting protrusion 421 can be provided on the first locking member 410, and the limiting groove 413 can be provided on the second locking member 420, achieving the same effect.

[0056] Further optional, see reference Figures 13-14 As shown, a first anti-rotation plane 1211 is provided on the inner sidewall of the mounting hole 121, and a second anti-rotation plane 423 is provided on the second locking member 420 to abut against the first anti-rotation plane 1211. This ensures the installation stability of the second locking member 420 and the base 100, thereby indirectly ensuring that the first locking member 410 can rotate stably.

[0057] Further optional, see reference Figures 13-14 As shown, the inner wall of the mounting hole 121 is provided with an anti-rotation groove 1212, and the second locking member 420 is provided with an anti-rotation protrusion 424. During actual installation, when the second locking member 420 is installed into the mounting hole 121, the anti-rotation protrusion 424 inserts into the anti-rotation groove 1212. This ensures the installation stability of the second locking member 420 and the base 100, thereby indirectly ensuring that the first locking member 410 can rotate stably. Alternatively, in an alternative embodiment, the inner wall of the mounting hole 121 is provided with an anti-rotation protrusion 424, and the second locking member 420 is provided with an anti-rotation groove 1212.

[0058] Alternatively, the anti-rotation protrusion 424 and the second anti-rotation plane 423 are arranged symmetrically about the center of the second locking member 420. This further ensures the installation stability of the second locking member 420 and the base 100.

[0059] Further options, see, for example Figure 12 As shown, the drive assembly 400 also includes a third locking member 430, which is mounted on the inner sidewall of the base 100. The third locking member 430 is provided with a limiting rib 431, and the second locking member 420 is provided with a limiting slot 422 that cooperates with the limiting rib 431. It can be understood that neither the anti-rotation protrusion 424 nor the second anti-rotation plane 423 can prevent the second locking member 420 from rotating about the mounting hole 121, but cannot prevent the second locking member 420 from moving axially along the mounting hole 121. In this embodiment, the added third locking member 430 is installed on the inner side wall of the base 100 and has a limiting rib 431 with an insertion limiting groove 413. In the actual installation process, after the first locking member 410 and the second locking member 420 are fitted together, they are inserted into the mounting hole 121. Then, the third locking member 430 is inserted from the inner side wall of the base 100, which can fix the second locking member 420 and prevent it from moving along the axial direction of the mounting hole 121, thereby ensuring the installation stability of the entire drive assembly 400 and the mounting hole 121.

[0060] Alternatively, two limiting ribs 431 may be provided, and limiting slots 422 may be provided on both sides of the second locking member 420. This can further improve the installation stability of the drive assembly 400.

[0061] Of course, it should be noted that in other embodiments of the present invention, the limiting rib 431 may be provided on the second locking member 420, and the limiting slot 422 may be provided on the third locking member 430.

[0062] Further options, see, for example Figure 12 As shown, the drive assembly 400 also includes an anti-detachment member 440, which is sleeved on the second locking member 420 and has an anti-detachment protrusion 441 that abuts against the end of the first locking member 410 where the drive part 411 is located. By providing the anti-detachment member 440, the connection stability between the second locking member 420 and the mounting hole 121 can be improved. On the other hand, the anti-detachment protrusion 441 on the anti-detachment member 440 can restrict the first locking member 410, preventing the first locking member 410 from disengaging from the second locking member 420, thereby ensuring that the drive assembly 400 can stably lock and unlock the energy storage power supply 20.

[0063] Optionally, the drive unit 411 includes an unlocking protrusion 4111 and an unlocking groove 4112 surrounding the unlocking protrusion 4111. The unlocking protrusion 4111 has an unlocking slot 41111. Understandably, during actual operation, the key 30 is inserted into the unlocking groove 4112, and the protrusion on the key 30 engages with the unlocking protrusion 4111 and the unlocking slot 41111, which improves the connection stability between the key 30 and the drive unit 411, thereby ensuring that the user can stably turn the key 30 to unlock or lock the energy storage power supply 20.

[0064] refer to Figure 2 and Figure 19 As shown, the base 100 includes a lower shell 120 and an upper shell 110. A mounting hole 121 is provided on the lower shell 120, and the upper shell 110 has multiple spaced-apart receiving slots 111, each for accommodating one energy storage power source 20. A movable component 300 is installed between the side wall of the upper shell 110 and the side wall of the lower shell 120. The upper shell 110 also has a through hole 112 communicating with the receiving slot 111, and an elastic positioning component 200 engages with the through hole 112. It is understood that installing the movable component 300 between the side walls of the upper shell 110 and the lower shell 120 improves the installation stability of the movable component 300 and allows it to be concealed inside the base 100, preventing the energy storage power source 20 from unlocking due to exposed force on the movable component 300. Multiple receiving slots 111 are provided on the upper shell 110. Each receiving slot 111 is used to accommodate one energy storage power source 20. Compared with the structure of a long slot 111, the energy storage power source 20 has better stability and avoids the phenomenon of the energy storage power source 20 being tilted.

[0065] Optional, see reference Figures 15-17 As shown, a fixed post 113 is provided on the side wall of the upper shell 110, and a movable elongated hole 330 that mates with the fixed post 113 is provided on the movable part 300. The fixed part 500 is connected to the fixed post 113 to prevent the movable part 300 from coming off the fixed post 113. It can be understood that by restricting the movable part 300 to the fixed post 113 by the fixed part 500, the axial movement of the movable part 300 along the fixed post 113 can be prevented. The movable elongated hole 330 is provided on the movable part 300. In actual operation, the mate between the movable elongated hole 330 and the fixed post 113 restricts and guides the movement direction of the movable part 300, preventing the movable part 300 from tilting.

[0066] Alternatively, the fixing member 500 may be a screw, with a gap between the screw head and the movable member 300. This prevents friction between the movable member 300 and the screw when it moves in the first direction, thus extending the service life of the movable member 300.

[0067] In some specific embodiments, the sidewall of the upper shell 110 is further provided with a first limiting portion 114 and a second limiting portion 115 spaced apart along the height direction of the energy storage power source 20. The first limiting portion 114 and the second limiting portion 115 respectively abut against two sidewalls of the elastic positioning member 200 spaced apart along the height direction of the energy storage power source 20. The first limiting portion 114 and the second limiting portion 115 abut against two sidewalls of the movable member 300 spaced apart along the height direction of the energy storage power source 20, which can completely restrict the vertical movement of the movable member 300, thereby avoiding the phenomenon of jamming caused by the skewness of the movable member 300. Further optionally, the first limiting portion 114 is a protrusion formed on the upper shell 110 and extending downward, and the second limiting portion 115 includes two spaced L-shaped protrusions.

[0068] The advantages of the energy storage device in this embodiment are as follows:

[0069] First, by controlling the key 30, multiple energy storage power sources 20 can be locked and unlocked, which is highly flexible and versatile.

[0070] Second: The first locking member 410 and the second locking member 420 share the same axial space, which can significantly reduce the size of the product;

[0071] Third, the screwless drive assembly 400 simplifies the production process and improves production efficiency.

[0072] This invention also discloses an energy storage device, including the aforementioned charging base 10 and multiple energy storage power sources 20. Each energy storage power source 20 is provided with a positioning groove 21. When an elastic positioning member 200 is inserted into the positioning groove 21, it can lock the energy storage power source 20 within the charging base 10. This energy storage device can simultaneously lock or unlock multiple energy storage power sources 20, making it convenient for users and improving user satisfaction.

[0073] The assembly process of the energy storage device in this embodiment is as follows:

[0074] Step 1: Arrange the anti-slip component 440, the first locking component 410, and the second locking component 420 in sequence, and then assemble them by fitting them together (see reference). Figure 11 (as shown)

[0075] Step 2: Insert the assembled structure from Step 1 into Mounting Hole 121, and use the third locking component 430 for insertion. The third locking component 430 secures the entire drive assembly 400 to the lower housing 120 (see reference). Figure 18 (as shown), and the movable part 300, the elastic positioning part 200, and the upper shell 110 are assembled into one piece (see reference). Figure 19 (as shown)

[0076] Step 3: Install the upper shell 110, which has the movable part 300 and the elastic positioning part 200, onto the lower shell 120, which has the drive assembly 400 assembled on it, and use screws to fix the upper shell 110 and the lower shell 120 together (see reference). Figure 20 (as shown)

[0077] Step 4: Insert key 30 into the first lock 410, turn key 30 to the unlock position, and then install the multiple energy storage power supplies 20 into the multiple receiving slots 111 of the base 100 in sequence to complete the assembly (see reference). Figure 1 (As shown).
