[0002] Chinese patent CN220180594U discloses a "Battery Pack Locking and Fixing Mechanism", which addresses the phenomenon of battery packs shaking inside the battery compartment. It designs a battery pack locking and fixing mechanism that uses four fixing components to limit the battery pack in the front, back, left and right positions. The structure is relatively complex, and locking and unlocking operations need to be performed one by one, which is relatively inconvenient to use. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a battery locking structure, a battery charging rack and a battery carrying charging mechanism. The battery locking structure is simple and stable, the unlocking operation is convenient, and the locking unit automatically resets after the battery is removed.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a battery locking structure, comprising:

[0005] The locking unit has at least a locked state in which it engages with the battery to prevent the battery from moving;

[0006] An unlocking unit is used to push the locking unit to disengage it from the locked state;

[0007] The holding unit has at least a first working position and a second working position. In the first working position, the holding unit abuts against the locking unit, and in the second working position, the holding unit disengages from the locking unit.

[0008] When the battery moves close to the locking unit, it can abut against the holding unit, so that the holding unit switches from the first working position to the second working position.

[0009] Furthermore, the locking unit also has an upper limit position, and the unlocking unit pushes the locking unit to switch it from the locked state to the upper limit position, during which the battery can move; the locking unit also has a lower limit position, and the locked state is located between the upper limit position and the lower limit position, and the holding unit abuts against the locking unit in the first working position to keep the locking unit in the lower limit position or to drive the locking unit to move to the lower limit position.

[0010] Furthermore, the locking unit includes at least a locking member that can rotate around a first pivot and a first elastic member, one end of the first elastic member being fixed and the other end being connected to the locking member, and the locking member having a protrusion that can engage with the battery.

[0011] Furthermore, in the lower limit state, the line connecting the two ends of the first elastic element is located below the center of the first rotating shaft; in the upper limit state, the line connecting the two ends of the first elastic element is located above the center of the first rotating shaft.

[0012] Furthermore, the holding unit includes a holding member that can rotate around a second pivot axis and a second elastic member. One end of the second elastic member is fixed and the other end is connected to the holding member. The holding member has a lower pressing arm that can abut against the locking member and a protrusion that can abut against the battery. The protrusion has an arc surface.

[0013] Furthermore, the locking component includes a first locking component and a second locking component arranged at an angle. The protrusion is located on the side of the first locking component away from the first rotating shaft. The second locking component has a connecting rod. The unlocking unit has a latching part that can be movably connected to the connecting rod. The inner wall of the latching part is at least partially arc-shaped and has a notch for the connecting rod to extend into, and elastic stop arms located on both sides of the notch.

[0014] This utility model also discloses a battery charging rack, including a charging end plate, an installation channel for battery insertion, and a battery locking structure.

[0015] This utility model discloses a battery-supporting charging mechanism, comprising:

[0016] The battery has teeth on its outer wall;

[0017] The charging rack.

[0018] Furthermore, the teeth extend along the entire length of the battery; rollers are provided in the mounting channel; the charging rack is hexagonal, and there are multiple charging racks, which are assembled to form a honeycomb pattern.

[0019] Furthermore, adjacent charging racks are fixedly assembled by connectors, which are either straight, three-pronged, or Z-shaped, with the Z-shaped connector being a tenon and mortise joint. The beneficial effects of this utility model are: 1) When the holding unit is in the first working position, it abuts against the locking unit, allowing the locking unit to automatically reset, ensuring that the battery can be locked when placed in the battery holder next time, without the need for manual reset, simplifying operation; 2) When the battery moves, it abuts against the holding unit, automatically switching the holding unit to the second working position. At this time, the holding unit disengages from the locking unit, allowing the unlocking unit to unlock the locking unit smoothly; 3) Utilizing the vertical relationship between the two ends of the first elastic member and the first rotating shaft, the locking unit has an upper limit state, a lower limit state, and a locked state. Once the locking member crosses the equilibrium state, it can freely rotate into the upper limit state or the lower limit state. The automatic rotation into different states and the existence of the upper limit state allow the locking unit to remain in the unlocked state without continuously pressing the unlocking unit, simplifying operation; the existence of the lower limit state allows the locking unit to remain in this state after automatic reset, facilitating the re-locking of the battery, and the locking unit in the locked state provides a stable and effective lock on the battery, preventing accidental unlocking; 4) The charging rack is secure... 5) The charging tray's internal rollers make battery insertion and removal easier and minimize wear on the battery surface; 6) The cylindrical connecting rod and locking mechanism effectively prevent jamming, avoid damage to the locking mechanism over time, and extend the overall lifespan; 7) The protrusions on the holding member facilitate the battery lifting the holding member while preventing battery damage; 8) The engagement of the battery teeth and the locking member's protrusions creates a locking structure between the battery and the charging tray. 9) The battery-carrying charging mechanism can be formed by splicing multiple charging racks into a honeycomb shape, which occupies a small overall volume and has few splicing restrictions, allowing for unlimited splicing and adapting to different usage scenarios; 10) When the connecting parts are Z-shaped, they form a mortise and tenon connection structure with the charging rack, which strengthens the radial strength between adjacent charging racks and makes the overall structure more stable; 11) The mechanical structure locking is more stable and reliable than electromagnetic locking, the locking operation is simple, the battery swapping time is short, and it can adapt to different battery swapping usage scenarios.

Detailed Implementation

[0050] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0051] like Figures 1-5 As shown, a battery locking structure includes a locking unit 2, an unlocking unit 3, and a holding unit 4. The locking unit 2 is used to lock the battery 1, the unlocking unit 3 is used to unlock the locking unit 2, and the holding unit 4 is used to hold the locking unit 2 in a lower limit state when the battery 1 is not installed, or to drive the locking unit 2 to move to the lower limit state when the battery 1 is removed. At the same time, with the cooperation of the battery 1, it can also switch from the state of pressing the locking unit 2 to the state of disengaging from the locking unit 2, and make the locking unit 2 have sufficient room for movement.

[0052] The locking unit 2 has at least a locked state, in which it engages with the battery 1, thereby preventing the battery 1 from moving away from the charging rack 5. In this embodiment, the locking unit 2 also has a lower limit state and an upper limit state, with the locked state located between the upper limit state and the lower limit state. In the locked state, the unlocking unit 3 pushes the locking unit 2, causing it to switch from the locked state to the upper limit state, at which point the battery 1 can move relative to the charging rack 5.

[0053] The unlocking unit 3 is used to push the locking unit 2, thereby causing the locking unit 2 to disengage from the locked state.

[0054] The holding unit 4 has at least a first working position and a second working position. In the first working position, the holding unit 4 abuts against the locking unit 2 to keep the locking unit 2 in the lower limit state, or to drive the locking unit 2 to move to the lower limit state. At this time, the holding unit 4 is in the first working position, which is a dynamic and continuous process. In other words, as long as the holding unit 4 abuts against the locking unit 2, it is defined as being in the first working position. In the second working position, the holding unit 4 disengages from the locking unit 2, thereby making it possible for the locking unit 2 to switch from the lower limit state to the locked state, or even switch to the upper limit state. When battery 1 moves closer to locking unit 2 relative to charging rack 5, it can abut against holding unit 4 before engaging locking unit 2, thereby switching holding unit 4 from the first working position to the second working position. At this time, holding unit 4 disengages from locking unit 2, providing sufficient space for the movement of locking unit 2, providing sufficient space for battery 1 to move to lock with locking unit 2, and also providing sufficient space for locking unit 2 to enter the upper limit position under the drive of unlocking unit 3 when battery 1 needs to be removed. Figures 6-8 As shown, the holding unit 4 is in the first working position at this time, as... Figures 1-8 As shown, the holding unit 4 is in the second working position at this time.

[0055] Specifically, such as Figures 15-17 ,like Figures 9-11 As shown, the locking unit includes at least a locking member 22 that can rotate around a first rotating shaft 21 and a first elastic member 23. The locking member 22 has a protrusion 221 that can engage with the battery 1. One end of the first elastic member 23 is fixed, and the other end is connected to the locking member 22. In this embodiment, the first rotating shaft 21 is fixedly connected to the outer casing 6. A first fixed shaft 61 parallel to the first rotating shaft 21 is also provided on the outer casing 6. Taking the battery 1 located below the locking unit 2 as an example, the height of the center of the first fixed shaft 61 is greater than the height of the center of the first rotating shaft 21. One end of the first elastic member 23 is fixedly connected to the first fixed shaft 61. Of course, in other embodiments, any structure can be used to fix the first elastic member 23, and there is no specific limitation.

[0056] like Figures 12-14 As shown, the locking member 22 includes a first locking member 222 and a second locking member 223 arranged at an angle. A first rotating shaft 21 is located at the angled connection between the first locking member 222 and the second locking member 223. The length of the first locking member 222 is greater than the length of the second locking member 223. A protrusion 221 is located on the side of the first locking member 222 away from the first rotating shaft 21, and is formed on the lower surface of the first locking member 222 after a portion of the first locking member 222 extends forward. A first connecting hole 225 for connecting the other end of the first elastic member 23 is formed near the protrusion 221 on the first locking member 222. The second locking member 223 has a connecting rod 224 that can be connected to the unlocking unit 3.

[0057] In the lower limit state, the line connecting the two ends of the first elastic member 23 is located below the center of the first rotating shaft 21. In other words, in the lower limit state, the center of the first fixed shaft 61, the center of the first connecting hole 225, and the center of the first rotating shaft 21 form a triangular structure with the long side pointing downwards. At this time, without the action of external force, the locking member 22 will always be in the lower limit state.

[0058] In the upper limit position, the line connecting the two ends of the first elastic element 23 is located above the center of the first rotating shaft 21. In other words, in the lower limit position, the center of the first fixed shaft 61, the center of the first connecting hole 225, and the center of the first rotating shaft 21 form a triangular structure with the long side facing upward. At this time, without the action of external force, the locking element 22 will always be in the upper limit position, and the unlocking unit 3 does not need to continuously push the locking element 22.

[0059] When the center of the first fixed shaft 61, the center of the first connecting hole 225, and the center of the first rotating shaft 21 are on the same straight line, the locking unit 2 is in a balanced state. Once this balanced state is exceeded, the locking member 22 will move automatically, including moving in the direction of the upper limit state and moving in the direction of the lower limit state.

[0060] The holding unit 4 includes a holding member 42 that can rotate around a second rotating shaft 41, and a second elastic member 43. One end of the second elastic member 43 is fixed, and the other end is connected to the holding member 42. The second elastic member 43 pulls the holding member 42, so that without external force, the holding member 42 tends to automatically switch to a state of abutting against the locking member 22. That is, without external force, the holding unit 4 tends to automatically switch to the first working position. The holding unit 4 tends to switch to the first working position, and then drives the locking unit 2 to move to the lower limit state and keeps the locking unit 2 in the lower limit state. As long as the holding unit 4 and the locking unit 2 abut against each other, it is defined as being in the first working position. The above continuous process can be defined as the holding unit 4 being in the first working position. In this embodiment, a second fixed shaft 62 parallel to the first rotating shaft 21 is also provided on the outer shell 6. One end of the second elastic member 43 is fixedly connected to the second fixed shaft 62. Of course, in other embodiments, any structure can be provided to fix the second elastic member 43, and no specific limitation is imposed.

[0061] like Figures 20-22As shown, the pressing member 42 has a lower pressing arm 421 and a protrusion 422. The lower pressing arm 421 can abut against the locking member 22. To facilitate the cooperation between the two, the side of the locking member 22 extends to form a protrusion 226. The protrusion 422 can abut against the battery 1. It is at least partially triangular, so that the battery 1 can push the pressing member 42 up through the protrusion 422. The tip of the protrusion 422 has a rounded surface to prevent the tip of the protrusion 422 from scratching the battery 1. A second connecting hole 423 for connecting the second elastic member 43 is provided near the second rotating shaft 41. The second connecting hole 423 is located above the height of the second rotating shaft 41.

[0062] Along the direction in which the battery 1 slides into the charging rack 5, the first fixed shaft 61, the second rotating shaft 41, the first rotating shaft 21, and the second fixed shaft 62 are arranged in sequence.

[0063] like Figure 6 As shown, the unlocking unit 3 includes a locking part 31 movably connected to the connecting rod 224 on the second lock 223, a sleeve 32 connected to the locking part 31, an extension rod 33 at least partially extending into the sleeve 32, and an automatic reset unlocking button 34 connected to the extension rod 33. To reduce wear from repeated use and to prevent jamming during use, the locking part 31 is movably locked onto the cylindrical connecting rod 224. Specifically, as... Figure 18 As shown, the inner wall of the latching part 31 is at least partially arc-shaped and has a notch 311 for the connecting rod 224 to extend into, and elastic stop arms 312 located on both sides of the notch 311. In this embodiment, the latching part 31 is a circular hole made of elastic material with the notch 311. During assembly, the connecting rod 224 presses against the elastic stop arms 312 and latches into the notch 311. The end faces of the sleeve 32 and the extension rod 33 do not abut against each other in the initial state. Only when the automatic reset unlocking button 43 pushes the extension rod 33 will they abut against each other axially, thereby driving the latching part 31 to push the connecting rod 224, and thus causing the locking member 22 to switch from the locked state to the upper limit state. The automatic reset unlocking button 43 can automatically reset after pushing the extension rod 33, which is a function that can be achieved by existing technology and will not be described in detail.

[0064] A battery charging rack includes a charging end plate 51, an installation channel 52 for inserting a battery 1, and the aforementioned battery locking structure.

[0065] A battery-supported charging structure includes a battery 1 and a charging rack 5, such as Figure 19 , Figures 20-23As shown, the outer wall of battery 1 has teeth 11, which can engage with the protrusions 221 of locking member 22. In this embodiment, the teeth 11 extend along the entire length of battery 1. In other embodiments, the teeth 11 may extend only on the side where battery 1 is first inserted into charging rack 5, and there is no specific limitation. In this embodiment, the teeth 11 have two inclined surfaces. The side facing the charging end plate 51 has a small inclination angle, which facilitates the movement of battery 1 into the charging rack 51. The side away from the charging end plate 51 has a larger inclination angle or no inclination, which makes the locking of locking member 22 and teeth 11 more secure.

[0066] like Figure 26 As shown, the charging rack 5 includes a charging end plate 51 located at one end, a mounting channel 52 for inserting the battery 1, and the aforementioned battery locking structure. The charging end plate 51 is provided with a communication terminal that can be electrically connected to the battery 1, and a roller 53 is provided in the mounting channel 52 to facilitate the sliding of the battery 1 into the charging rack 5.

[0067] In the above structure, the number of charging racks 5 is one, but multiple charging racks 5 can also be combined. In this embodiment, for example... Figure 28 , Figure 28 As shown, the charging rack 5 has a hexagonal shape. Here, hexagonal means that the projection of the charging rack 5 is a hexagonal structure. The outer sides of multiple charging racks 5 are attached to each other to form a honeycomb pattern.

[0068] To connect multiple charging racks 5, a connector 7 can be installed on the end face of the charging rack 5 near the entrance of the mounting channel 52. This connector 7 securely assembles the end face of the charging rack 5. Specifically, it can be a three-pronged type or a straight type, such as... Figure 26 As shown. Figure 27 , Figure 15 As shown, a Z-shaped connector 7 can also be provided within the charging end plate 51 to fix adjacent charging racks 5 together. Specifically, the Z-shaped connector 7 is a tenon and mortise joint to achieve fixed assembly of adjacent charging racks 5. This mating structure strengthens the radial strength between adjacent charging racks 5, resulting in higher overall structural stability.

[0069] The process of charging battery 1 by placing it into charging rack 5 is as follows: battery 1 is inserted into the inlet end of charging rack 5. Under the action of roller 53, battery 1 moves horizontally within mounting channel 52 and approaches charging end plate 51 by rolling friction, with the teeth 11 of battery 1 facing locking unit 2. Initially, holding unit 4 is in the first working position, abutting against locking unit 2, keeping locking unit 2 in the lower limit position, i.e., locking unit 2 is in the direction facing the installation position of battery 1. When battery 1 moves to abut against holding member 42, battery 1 drives holding member 42 to rotate away from protrusion 226, i.e., holding unit 4 switches from the first working position to the second working position. As battery 1 moves forward, battery 1 continuously pushes holding member 42 upward. Initially, the holding member 42 remains in the second working position; the locking member 22 tilts slightly upward under the drive of the battery 1, and during the forward movement of the battery 1, the protrusion 221 and the tooth 11 of the battery 1 mesh with each other, so that the battery 1 cannot move in the opposite direction, thus locking the battery 1; although the locking member 22 tilts slightly upward to enter the locked state, it still has not crossed the equilibrium state. Since the center of the first fixed shaft 61, the center of the first connecting hole 225, and the center of the first rotating shaft 21 form a triangular structure with the long side facing down, the locked state is relatively stable under the pull of the first elastic member 23. Under the pull of the first elastic member 23, the locking member 22 will remain in the locked state; the battery 1 moves to the communication terminal of the charging terminal board 51 for electrical connection.

[0070] The process of removing battery 1 from charging holder 5 involves applying external force to press the automatic reset unlock button 34, causing the extension rod 33 to move closer to the sleeve 32, which in turn causes the locking part 31 to push the connecting rod 224. ​ Taking the direction shown as an example, when the holding unit 4 switches to the second working position, the holding member 42 disengages from the locking member 22, and the locking member 22 rotates clockwise to the upper limit position. At this time, even if the extension rod 33 resets, the locking member 22 can remain in the upper limit position under the pull of the first elastic member 23. That is, pressing the automatic reset unlock button 34 once can unlock the battery without continuously pressing the automatic reset unlock button 34. Under the action of the roller 53, the battery 1 moves horizontally away from the charging end plate 51 in the installation channel 52. At this time, the holding unit 4 abuts against the locking unit 2, preparing for the locking unit 2 to re-enter the locked state until it disengages from the charging rack 5.

[0071] When the battery 1 is disengaged from the holding member 42, the second elastic member 43 pulls the holding member 42 to rotate counterclockwise, and the holding member 42 switches from the second working position to the first working position. During the process of the holding member 42 changing its working position, the lower pressing arm 421 of the holding member 42 abuts against the protrusion 226 of the locking member 22, driving the locking unit 2 to move to the lower limit state, so that the locking unit 2 automatically rotates counterclockwise to reset without manual reset.

[0072] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
