Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a detachable battery pack. Background Art

[0002] A battery is a device that contains an electrolyte solution and metal electrodes to generate an electric current in a cup, tank or other container or part of a composite container that can convert chemical energy into electrical energy.

[0003] A battery pack generally refers to a combined battery, which mainly refers to the processing and assembly of a lithium battery pack. It is a product that is combined and processed into customer needs through a battery packaging process, including battery cells, battery protection boards, battery connectors, label papers, etc., and is used to store battery cells. When the battery cell is disassembled, the battery pack is not easy to disassemble due to limited space in the shell.

[0004] Among them, the "removable battery pack" disclosed in the application number "CN202020262742.2" is also an increasingly mature technology. It adopts a box cover and a box body, and uses a convex structure of a card slot and a protruding block to facilitate the storage and access of the battery pack in the accommodating cavity. It has a simple structure, a reasonable layout, and the connection between adjacent battery packs is simple and fast. At the same time, the battery pack is easy to replace and easy to disassemble, which is convenient for the maintenance of the battery pack;

[0005] After searching "CN202121351188.6", the "an easily disassembled lithium battery pack" disclosed is also an increasingly mature technology. The detachable cover shell cooperates with the battery box. This structure advantageously ensures that when the stop block of the cover shell is pushed into the direction of the fitting hole to deform and reset in the fitting hole, the stability of the battery box and the cover shell is guaranteed. The connecting rod is arranged in the handle. This structure advantageously ensures that when the cover shell needs to be removed, the switch end of the connecting rod in the handle is pulled to rotate the connecting rod along the connection with the handle shaft, so that the trigger end of the connecting rod contacts the stop block, and the stop block is moved along the direction of the fitting surface with the fitting hole and pushed out of the fitting hole, thereby realizing the portable removal of the cover shell.

[0030] In this embodiment, a plurality of shock absorbing springs 11 are installed on the inner wall of one side of the outer box 1 , and a buffer plate 12 is connected to the other end of the shock absorbing spring 11 .

[0031] Specifically, the outer box 1 is used to load the battery box 3, and the battery box 3 is used to neatly place the batteries 33 and effectively protect the batteries 33. By opening the heat dissipation holes 31 and the battery slots 32, the heat of the batteries 33 will increase when generating electricity. The batteries 33 are isolated by the battery box 3, and the heat of the batteries 33 when generating electricity is volatilized. The driving mechanism 4 is convenient for lifting the bottom plate 443, and the battery box 3 is taken out from the outer box 1. The driving motor 42 is started to rotate the turntable 43, and the turntable 43 drives the raised block 44 to rotate synchronously. When the protruding block 44 rotates and the rotating wheel 45 rotates to the travel block 41, the protruding block 44 slides on the sliding plate 46 through the sliding column 47 on the other side, thereby lifting the protruding block 44, and then the protruding block 44 lifts the bottom plate 443, and then the bottom plate 443 lifts the battery box 3 on the top together, and the shock-absorbing spring 11 and the buffer plate 12 can be used to reduce the shock of the battery box 3 to prevent the battery box 3 from shaking and damaging the battery 33, thereby reducing the probability of damage to the battery 33 caused by shaking and extending the service life of the battery 33.

[0032] See also Figure 2 As shown, the problem of reasonable card connection of multiple battery boxes 3 is solved. In this embodiment: the battery box 3 close to the buffer plate 12 is card-connected to the second battery box 3 and the card slot 302 matched with the card plate 301 through the card plate 301, and a pull rod is installed on the other side of the battery box 3, and the side of the battery box 3 away from the buffer plate 12 is card-connected to the front battery box 3 through the card slot 302, and the other end is in contact with the inner wall of the outer box 1.

[0033] Specifically, by cooperating with the clamping plate 301 and the clamping slot 302 , multiple battery boxes 3 can be clamped in sequence inside the outer box 1 , and the pull rod facilitates taking out the battery box 3 when the battery box 3 is lifted up by the bottom plate 443 .

[0034] See also Figure 3As shown, the problem of effectively limiting the downward movement of the protruding block 44 is solved.

[0035] Specifically, the limit block 441 is used to protect the surrounding of the protruding block 44. The diameter of the moving hole 442 of the limit block 441 is larger than that of the turntable 43, so that when the protruding block 44 slides on the sliding plate 46 through the sliding column 47, the moving hole 442 of the turntable 43 can limit the protruding block 44 from sliding down, thereby limiting the protruding block 44. The bottom plate 443 is used to support the battery box 3.

[0036] See also Figure 1 As shown, to discharge the heat of the battery 33, in this embodiment: the outer box 1 is fixedly mounted with a first L-shaped block 13 on all four sides near the top, wherein the outer box 1 is provided with air holes 14 on three sides near the top.

[0037] Specifically, the heat of the battery box 3 is discharged through the vent holes 14 , which can effectively dissipate heat for the battery 33 .

[0038] See also Figure 1 As shown, the outer box 1 and the box cover 2 are movably buckled. In this embodiment: a sponge pad 21 is fixedly connected to the bottom of the box cover 2, and circular holes are opened in the sponge pad 21 at the corresponding positions of the batteries 33. Buckles 22 are fixedly installed around the box cover 2, and the second L-shaped block of the buckle 22 is detachable from the first L-shaped block 13. A fixing plate 23 is installed in the middle of the top of the box cover 2, and the middle of the fixing plate 23 passes through both sides of the handle through a rotating shaft.

[0039] Specifically, the sponge pad 21 effectively protects the top of the battery 33, and the outer box 1 can be movably closed and buckled by cooperating with the first L-shaped block 13 and the second L-shaped block.

By providing the heat dissipation holes 31, the battery slots 32 and the air holes 14, the heat generated by the batteries 33 during power generation will be increased, and the batteries 33 are isolated by the battery box 3, thereby volatilizing the heat generated by the batteries 33 during power generation;

[0043] After use: if the battery box 3 needs to be taken out, start the driving motor 42 and rotate the turntable 43. The turntable 43 drives the protruding block 44 to rotate synchronously. When the protruding block 44 rotates, when the rotating wheel 45 rotates to the travel block 41, the protruding block 44 slides on the sliding plate 46 through the sliding column 47 on the other side, and then lifts up the protruding block 44. After the protruding block 44 is lifted, the bottom plate 443 is lifted up, and then the bottom plate 443 lifts up the battery box 3 on the top together. The staff picks up the pull rod with one hand and supports the other side of the battery box 3 with the other hand to take out the multiple battery boxes 3 that are connected.
