[0039] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0040] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0041] This embodiment provides a battery module stacking device, see Figure 1 and Figure 2 , including an adjustment plate 5 and a first mounting member for limiting the length direction and width direction of the battery module; the adjustment plate 5 is provided with a first adjustment portion capable of adjusting the position of the first mounting member along the length direction of the battery module and along the width direction of the battery module; the first mounting member is connected to the first adjustment portion.
[0042] When in use, the battery cells and other components are assembled into a battery module on the inner side of the first mounting member and the adjustment plate 5. The first mounting member can simultaneously limit the length and width directions of the battery module, that is, directly limit the four corners of the battery module. By changing the connection position of the first adjustment part and the first mounting member, the length and width of the battery module can be changed, that is, it can adapt to changes in the length, height and number of cells in the battery module, and has strong versatility.
[0043] The adjustment plate 5 can be made of aluminum.
[0044] As an optional implementation, see Figure 1 , Figure 3 and Figure 4 The first adjusting portion includes elongated holes 53 arranged side by side. Preferably, the elongated holes 53 are parallel to each other, and the elongated holes 53 can be parallel to the width direction of the battery module ( Figure 3As shown in FIG. 1 ), it may be parallel to the length direction of the battery module, or it may be arranged obliquely, and the purpose of adjusting the position of the first mounting member can be achieved. The number, spacing and direction of the long holes 53 can be flexibly adjusted as needed. In other embodiments, the first adjusting portion may also be other structures, such as the first adjusting portion includes threaded holes in a rectangular array.
[0045] As a preferred embodiment, see Figure 1 , Figure 3 and Figure 4 , the first adjustment portion also includes a first notch 55 located outside the long hole. The first notch 55 is composed of interconnected T-shaped slots, and can also adjust the position of the first mounting member along the length direction and width direction of the battery module at the same time. The adjustment plate 5 has to bear the weight of the battery module and the weight of the first mounting member and other components. The first notch 55 is set on both sides of the long hole 53 instead of directly extending the long hole 53 to a position close to the end of the adjustment plate 5 in order to maximize the adjustment range of the first mounting member while ensuring the structural strength of the adjustment plate 5.
[0046] As an optional implementation, see Figure 1 and Figure 2 The first mounting member includes four L-shaped plates 8 perpendicular to the adjustment plate 5, and the two sides of the L-shaped plates 8 limit the length direction and width direction of the battery module respectively. The L-shaped plate 8 can be integrally formed or formed by splicing two plates.
[0047] As an optional implementation, see Figure 1 , Figure 2 and Figure 5 , the L-shaped plate 8 is connected to the L-shaped plate fixing block 9 by bolts and washers. The L-shaped plate fixing block 9 is connected to the elongated hole 53 and / or the first notch 55 by bolts and washers. The material of the L-shaped plate 8 can be stainless steel. A fixing plate pad 10 can be arranged between the L-shaped plate fixing block 9 and the adjustment plate 5. In other embodiments (not shown in the figure), the L-shaped plate 8 can also be directly connected to the elongated hole 53 and / or the first notch 55 by bolts. The use of bolt connection can facilitate the adjustment of the position of the L-shaped plate 8.
[0048] As an optional implementation, see Figure 1 and Figure 2 The battery module stacking device further includes a second mounting member capable of limiting the battery module width direction; the adjusting plate 5 is provided with a second adjusting portion capable of adjusting the position of the second mounting member along the battery module width direction; the second mounting member is connected to the second adjusting portion. Figure 1 and Figure 3, the second adjustment part includes a second long strip notch 54 arranged in parallel; the second mounting part includes a first stabilizing plate 11 and a second stabilizing plate 13 arranged oppositely and parallel to the length direction of the battery module; the first stabilizing plate 11 is connected to the first stabilizing plate fixing block 12 by bolts and gaskets; the first stabilizing plate fixing block 12 is connected to the second notch 54 by bolts and gaskets; the second stabilizing plate 13 is connected to the second stabilizing plate fixing block 14 by bolts and gaskets; the second stabilizing plate fixing block 14 is connected to the second notch 54 by bolts and gaskets. The number and spacing of the second notches 54 can be flexibly adjusted as needed. By adjusting the relative distance between the first stabilizing plate 11 and the second stabilizing plate 13, the change in the length of the battery cell can be adapted. The number of the first stabilizing plate 11 and the second stabilizing plate 13 can be flexibly adjusted. The material of the first stabilizing plate 11 and the second stabilizing plate 13 is preferably rubber, or other flexible materials that are not easy to generate static electricity. The first stabilizing plate 11 and the second stabilizing plate 13 are preferably fixed with countersunk bolts, so that it can better protect the battery module and ensure that the battery cell is not bumped during module stacking and subsequent transportation.
[0049] As an optional implementation, see Figure 1 and Figure 2 The adjusting plate 5 is provided with a first cushion block 15 whose outer end surface is parallel to the adjusting plate 5. The first cushion block 15 is connected to the adjusting plate 5 by bolts. The first cushion block 15 plays a buffering role.
[0050] As an optional implementation, see Figure 1 and Figure 6 The adjusting plate 5 is connected with a slider 6 and a guide block 7 which is in the same direction as the sliding direction of the slider 6 and is located between the sliders 6. The slider 6 and the L-shaped plate 8 are respectively located on both sides of the adjusting plate 5. The guide block 7 cooperates with the slide rail of the battery module stacking device in the existing design, and the slider 6 cooperates with the slide table of the battery module stacking device in the existing design, so that after the battery module is assembled, the battery module stacking device and the battery module are transferred to the next process by sliding.
[0051] As a preferred embodiment, see Figure 1 , Figure 3 , Figure 4 The adjusting plate 5 is hollow and includes a first connecting plate 51 and a second connecting plate 52 connected to each other; the first connecting plate 51 is provided with a long hole 53, a first notch 55, and a second notch 54.

The second connecting plate 52 is connected to the moving plate 4 by bolts, and the moving plate 4 is connected to the slider 6 by bolts. Figure 6The shape of the guide block 7 is shown. The lower part of the guide block 7 is matched with the slide rail, and the upper part is interference-fitted with the movable plate 4, the second connecting plate 52, and the first connecting plate 51. The adjustment plate 5 is designed as the first connecting plate 51 and the second connecting plate 52, so as to facilitate the adjustment of the L-shaped plate 8, the first stabilizing plate 11, the second stabilizing plate 13 and the slider 6. The movable plate 4 can enhance the stability of the entire structure. The first connecting plate 51 and the second connecting plate 52 can have completely identical structures, and can be replaced with each other when they are completely identical.
