[0051] The working principle of the present utility model:

[0052] In this embodiment, the mother tray 1 is provided with positioning pins and the supporting columns of the child tray 2 for positioning and supporting the child tray 2. The child tray 2 is stacked on the mother tray 1. A plurality of linear guide rails are provided on both the mother tray 1 and the child tray 2. The module fixture 3, the length fixture 11, and the limiting unit 4 provided with the width elastic connection unit 6 can all be slidably matched with the linear guide rails through sliders; a plurality of module fixtures 3 are arranged side by side horizontally, and adjacent module fixtures 3 are connected by the width elastic connection unit 6. Among them, the two module fixtures 3 arranged in the middle (at the position of the center line B-B) are fixed on the child tray 2 and connected by the width elastic connection unit 6. The limiting unit 4 is provided with a limiting displacement range, which can limit the distance between the two module fixtures 3 and can be linked with each other. The above-mentioned "in the middle" refers to the central position of the child tray 2, that is, close to the position of the center line B-B. Further, the above two adjacent module fixtures 3 arranged in the middle (at the center line B-B position) are connected by the width elastic connection unit 6 fixed on the child tray 2, that is, the clamping arms 31 of the two module fixtures 3 that are in the middle and not in the same module fixture 3 are connected by the width elastic connection unit 6 fixed on the child tray 2; the module fixture 3 is formed by two clamping arms 31 that can move left and right along the X-axis direction and a bottom plate. The area between the two clamping arms 31 of the same module fixture 3 is used to place the battery cells, and the left and right sides of the battery cells are limited by the two clamping arms 31 of the module fixture 3. In this embodiment, the center line B-B is the innermost or the most central, the central position. Relatively, the positions at the left and right ends of the child tray 2 are the outermost positions among several module fixtures 3. When pulling the two module fixtures 3 at the left and right ends of the child tray 2 away from the center line B-B respectively, that is, pulling the clamping arm 31 of the leftmost module fixture 3 in the direction away from the center line B-B, and pulling the clamping arm 31 of the rightmost module fixture 3 in the direction away from the center line B-B; after the outermost module fixture 3 moves to the left to the maximum distance, it drives the adjacent module fixture 3 on the right to move to the left. Since the clamping arm 31 of the outermost module fixture 3 is connected to the clamping arm 31 of the adjacent module fixture 3 on the right by the width elastic connection unit 6, and the clamping arm 31 of the adjacent module fixture 3 on the right is adjacent to the next adjacent module fixture 3 on the right, so as to realize synchronous driving of a plurality of adjacent module fixtures 3 and adjust the distance between a plurality of module fixtures 3 in a linkage manner, which is convenient for placing the battery cells or batteries. A receiving groove is formed between the two clamping arms 31 of the same module fixture 3. The horizontal movement of the module fixture 3 is convenient for placing the battery cells. Similarly, when it is necessary to move the module fixture 3 along the X-axis direction towards the center line, it is necessary to move the two outermost module fixtures 3 on the left and right towards the center line B-B to squeeze, so as to realize the linkage of a plurality of receiving grooves moving inwards and drive the battery cells or batteries to move. The position of the center line B-B is the center position of the child tray 2, and the so-called "towards the center direction" is the direction towards the center line B-B.

[0053] In this embodiment, as shown in the attached Figure 3As shown, after the mother tray 1 is fitted with the child tray 2, the length fixture 11 passes through the child tray 2 and surrounds the front and rear ends of the accommodation groove. The width of the accommodation groove is the distance between the clamping arms 31 of the module fixture 3. The length of the accommodation groove is controlled by the length fixture 11. The length fixture 11 can move back and forth through the slider, that is, move along the Y-axis direction. The length fixture 11 includes an upper clamping part and a lower clamping part that can both be compressed and moved up and down. When the distance between the upper clamping part and the lower clamping part is shortened, the length of the accommodation groove becomes shorter, pressing the front and rear ends of the battery cell. When the distance between the upper clamping part and the lower clamping part is increased, the length of the accommodation groove becomes longer, releasing the front and rear ends of the battery cell. The positive resetting part 18 of the upper clamping part can make the upper clamping part reset after pressing or releasing the rear end of the battery cell, providing an elastic force for pressing the battery cell forward along the Y-axis. The positive resetting part 18 of the lower clamping part can make the lower clamping part reset after pressing or releasing the front end of the battery cell, providing an elastic force for pressing the battery cell backward along the Y-axis.

[0054] When the battery or battery cell is loaded into the box body, the box body covers the child tray 2 from top to bottom, then the box body and the child tray are flipped together by a certain degree. The flipped child tray 2 is located at the top of the box body. Finally, the child tray 2 is taken out, and each battery cell falls to the bottom of the box body, completing the loading of the battery cell or battery cells into the box.

[0055] The follower 9 can be selected as a pin structure. A follower 9 is arranged upward in the middle of each length fixture 11. A follower hole 17 is provided in the middle of the module fixture 3. The follower 9 is matched with the follower hole 17, so that the length fixture 11 and the module fixture 3 move together, improving the clamping accuracy and synchronous movement accuracy of the two for the corresponding battery cells.

[0056] In this embodiment, the width elastic connection unit 6, the length elastic connection unit 10, the first elastic member 7, the second elastic member 14, the third elastic member 8, and the positive resetting member 18 can all be selected as elastic structures such as springs to provide elastic force.

[0057] As Figure 6 shown, a third elastic member 8 is also connected between the connection seat 12 and the child tray 2 to buffer the pulling force or pushing force of the clamping arm or the external force mechanism on the connecting shaft.

[0058] In this embodiment, the elastic force provided by the width elastic connection unit 6 in the middle can be selected to be greater than the elastic forces of other width elastic connection units 6. The limiting unit 4 is in a "cross" shape structure. The width elastic connection unit 6 in the middle is fixed on the limiting unit 4 and is installed together at the middle position of the child tray 2. In addition, the limiting unit 4 and the width elastic connection unit 6 can move left and right along the slide rail in the X-axis direction. The limiting unit 4 has a track that can provide for the clamping arm 31 to move back and forth left and right, and convex blocks are provided at both left and right ends of the track to limit the movement range of the clamping arm 31.

[0059] The first convex block and the second convex block provided by the limit mechanism 5, the first convex block is provided on one of the adjacent two width jigs, the second convex block is provided on the other width jig of the adjacent two, and the first convex block and the second convex block are respectively located on the left and right sides (outer sides) of the limit unit 4, so as to control the displacement amount of the limit unit 4 moving along the X-axis. In this embodiment, a placement groove 16 for placing a water-cooled plate is formed between two adjacent module jigs 3. The distance between two module jigs 3, that is, the distance between the clamping arms 31 of two different module jigs 3, expands or contracts the placement groove 16 as the position adjustment component changes, so as to release or clamp the water-cooled plate. The split support block 15 can separate the two clamping arms 31 to further control the distance between two adjacent width jigs, prevent the two adjacent width jigs from approaching infinitely, and at the same time protect the water-cooled plate placed in the placement groove 16 from being damaged by excessive extrusion.

It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
