[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example

[0037] Reference Figure 1 and Figure 2 As shown, in one embodiment of this utility model, a detachable power bank locking device is disclosed, which is disposed between adjacent charging compartments in a server rack, for locking or unlocking a power bank placed in the charging compartment for charging. The device includes...

[0038] Casing 1;

[0039] The locking mechanism 2 is disposed inside the housing 1. The locking mechanism 2 includes an elastic element 23 and a first slider 21 and a second slider 22 that are slidably connected. The two ends of the elastic element 23 abut against the first slider 21 and the second slider 22 respectively, and the elastic element 23 is in a compressed state. The first slider 21 and the second slider 22 are both provided with locking tongues. The locking tongue 211 of the first slider 21 and the locking tongue 221 of the second slider 22 protrude from both sides of the housing 1 respectively.

[0040] The driving mechanism 3 drives the first slider 21 and the second slider 22 to move closer together;

[0041] Buckles 4a and 4b are connected to both sides of the housing 1. Buckles 4a and 4b engage with the slots of the cabinet. Buckles 4a and 4b are connected to levers.

[0042] The detachable power bank locking device described in this embodiment allows for quick engagement after insertion into the cabinet. This is achieved by the latches 4a and 4b on both sides of the housing 1 engaging with the cabinet's slots, simplifying the assembly process. Disassembly is achieved by pressing the levers 4a1 and 4b1 and pulling out the housing 1, allowing for flexible replacement or maintenance of the locking device. The elastic element 23 pushes the first slider 21 and the second slider 22 back to their original positions, ensuring that the locking tongues 211 and 221 of the first slider 21 and the second slider 22 are always locked, preventing accidental disengagement of the locking tongues 211 and 222 from the power bank's locking hole and causing locking failure. The driving mechanism 3 drives the first slider 21 and the second slider 22 closer together, allowing for individual retraction of the locking tongues 211 and 221, enabling simultaneous locking and unlocking of two power banks.

[0043] Reference Figure 2 As shown, in one embodiment of this utility model, the elastic element 23 is preferably a spring.

[0044] Reference Figure 2 As shown, in one embodiment of this utility model, the driving mechanism 3 drives the first slider 21 and the second slider 22 to move along the extension and retraction direction of the elastic element 23. The locking tongue 211 of the first slider 21 and the locking tongue 221 of the second slider 22 move along the extension and retraction direction. The two buckles 4a and 4b are symmetrically distributed on both sides of the housing 1 along the extension and retraction direction.

[0045] Reference Figure 2 As shown, in one embodiment of the present invention, the housing 1 includes an upper housing 12 and a lower housing 11 connected by a cover. The upper housing 12 and the lower housing 11 form a closed inner cavity. The locking mechanism 2 and the driving mechanism 3 are both disposed in the inner cavity. The housing 1 can prevent impurities from entering the locking mechanism 2 and the driving mechanism 3, thereby reducing the phenomenon of mechanism jamming.

[0046] Reference Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment of this utility model, the second slider 22 is slidably disposed above the first slider 21. Both the first slider 21 and the second slider 22 are provided with spring grooves. The spring grooves 217 of the first slider 21 and 224 of the second slider 22 form a spring mounting cavity for accommodating the elastic element 23. Both the first slider 21 and the second slider 22 are also provided with limiting portions. The limiting portion 212 of the first slider 21 and the limiting portion 222 of the second slider 22 are respectively located on both sides of the spring mounting cavity. After the elastic element 23 is placed in the spring mounting cavity, the elastic element 23... Both ends can respectively abut against the limiting part 212 of the first slider 21 and the limiting part 222 of the second slider 22, so that the elastic element 23 can push the first slider 21 and the second slider 22 to reset. Furthermore, the first slider 21 abuts against the limiting part 222 of the second slider 22 along its sliding direction. The limiting part limits the first slider 21 and prevents the first slider 21 from excessively squeezing the elastic element 23. The second slider 22 abuts against the limiting part 212 of the first slider 21 along its sliding direction. The limiting part limits the second slider 22 and prevents the second slider 22 from excessively squeezing the elastic element 23.

The rotating shaft 341 is rotatably connected to the housing 1. The drive motor drives the rotating shaft 341 to rotate. When the steering block rotates counterclockwise and clockwise, it can respectively drive the second slider 22 and the first slider 21 to move, thereby locking and unlocking the power banks on both sides of the housing 1. Specifically, the sidewalls of the first cam 344 and the second cam 342 are provided with a toggle surface and an arc adjacent to the toggle surface. On the outer end face, the actuating surface 3442 of the first cam 344 abuts against the first slider 21, specifically, the actuating surface 3442 abuts against the protrusion 214 of the first slider 21. When the steering block rotates clockwise, the actuating surface 3442 can push the first slider 21, causing the locking tongue 211 to retract into the housing 1 to the unlock position, thereby unlocking the power bank, while the second slider 22 remains stationary. The actuating surface 3421 of the second cam 342 abuts against the second slider 22, specifically, the actuating surface 3421 abuts against the protrusion 226 of the second slider 22. When the steering block rotates counterclockwise, the actuating surface 3421 can push the second slider 22, causing the locking tongue 221 to retract into the housing 1 to the unlock position, thereby unlocking the power bank, while the first slider 21 remains stationary.

[0048] Reference Figure 7 As shown, in one embodiment of this utility model, both ends of the rotating shaft 341 are provided with a connector 345 smaller than the rotating shaft 341. The connector 345 is respectively inserted into the mounting hole 123 of the upper housing 12 and the mounting hole 112 of the lower housing 11 to realize the positioning of the rotating shaft 341.

[0062] The working principle of the detachable power bank locking device described in this utility model is as follows:

[0063] During assembly, press the two levers 4a1 and 4b1 to bring the two latches 4a and 4b close to the housing 1. Then, insert the housing 1 into the cabinet to the predetermined position and release the two levers 4a1 and 4b1. The two latches 4a and 4b will reset and insert into the slots of the cabinet, thus locking the housing 1 to the cabinet. During operation, taking the charging compartment corresponding to the locking tongue 221 as an example, the drive motor drives the locking tongue 221 to retract. After the power bank is inserted into the charging compartment, the locking tongue 221 resets under the elastic force of the elastic element 23 and inserts into the lock hole of the power bank, thus locking the power bank. After the power bank is fully charged, the drive motor drives the locking tongue 221 to retract, releasing the locking tongue 221 from the power bank. The power bank can then be removed. When the locking device needs to be upgraded or maintained, press the two levers to release the lock between the housing 1 and the cabinet, disconnect the electrical connection of the drive mechanism 3, remove the locking device, and then assemble a new locking device.
