[0002] With the continuous development of new energy technologies, lithium batteries, as efficient and environmentally friendly energy storage devices, have been widely used in electric vehicles, energy storage systems, and other fields. During the assembly process of lithium battery packs, multiple single lithium battery cells need to be combined and fixed to ensure the performance and safety of the battery pack. Traditional lithium battery pack assembly fixtures are often only suitable for lithium battery cells of specific sizes and shapes, with poor adaptability, and cannot meet the assembly requirements of lithium battery packs of different specifications. Therefore, designing a highly adaptable lithium battery pack assembly fixture is of great practical significance. Utility Model Content

[0005] Preferably, there are two groups of drive blocks, which are symmetrically distributed on both sides of the middle of the bidirectional screw. Here, the two groups of clamps can move towards each other at the same time, so that the clamped battery pack can be kept in the center position on the workbench.

[0006] Preferably, the surface of the handle is covered with a rubber sleeve, which can improve the comfort of holding the handle and reduce the friction between the palm and the handle that may cause discomfort in the hand.

[0007] Preferably, there are four groups of clamps, which are symmetrically distributed on both sides of the middle of the workbench surface. Here, battery packs of different shapes can be fixed, further expanding the scope of use of the clamp.

[0008] Preferably, the surface of the adjusting knob is fixedly connected with anti-skid ribs, and the anti-skid ribs are evenly distributed on the surface of the adjusting knob. Here, the friction force when rotating the adjusting knob can be increased to avoid slipping when rotating the adjusting knob.

[0010] Preferably, the surface of the splint is provided with a T-slot and a limit slot, and the surface of the protective pad is fixedly connected to a T-rod and a limit rod, the T-rod is slidably connected to the inside of the T-slot, and the limit rod is inserted into the inside of the limit slot. The limit rod and the T-rod are made of the same material as the protective pad. Here, the protective pad and the splint can be disassembled and assembled, which facilitates the replacement of the protective pad that has aged and damaged due to long-term use, thereby increasing the service life of the splint.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. The utility model provides a bidirectional screw rod, a driving block, a handle, a clamping block, a screw and an adjusting knob. When clamping the battery pack, the battery pack is first placed between the two sets of clamping plates, and then the handle is held and turned. The handle drives the bidirectional screw rod between the first fixed block and the second fixed block to rotate. While the bidirectional screw rod rotates, it drives the two sets of driving blocks and the clamping plates to move and clamp the battery pack. Then the clamping block is moved so that the clamping block is attached to the periphery of the battery pack. Then the adjusting knob is turned, and the adjusting knob drives the screw rod to rotate in the threaded hole. The bottom of the screw rod is tightly against the inner bottom surface of the slide groove. Then, the remaining clamping blocks can be operated according to the above steps, so that battery packs of different specifications and sizes can be clamped by adjusting the distance between the two sets of clamping plates. At the same time, battery packs of different shapes can also be fixed, thereby improving the scope of application and practical value of the clamp.

[0013] 2. In the present invention, a protective pad, a No. 2 rod, a limit rod, a T-slot and a limit slot are provided. If the protective pad becomes aged or damaged after long-term use and needs to be replaced, first hold the edge of the protective pad to pull the limit rod out of the limit slot, and then pull the protective pad from one side of the splint to pull the T-rod on the protective pad out of the T-slot on the splint, thereby protecting the battery pack and avoiding pinching the battery pack. At the same time, the protective pad and the splint can be disassembled and assembled, which is convenient for later replacement of the protective pad that has aged and damaged due to long-term use, and is beneficial to increasing the service life of the splint.
