[0055] A battery stacking device refers to a tooling for sequentially combining and assembling multiple single cells in a corresponding structural order. The existing battery stacking device first forms a stacked body by connecting multiple batteries in series and / or in parallel, then compresses the stacked body to the designed size, and then fixes it in the form of steel straps and / or cable ties, etc., and then stacks multiple batteries into a battery pack. Among them, when manually stacking and assembling multiple batteries, the randomness of the alignment of multiple batteries is very large, which will result in poor flatness of the bottom and side plates of the batteries.

[0056] In current battery packs, batteries are mostly grouped in single-row or double-row battery packs. The stacking tooling of this structure is relatively simple and easy to put into a box to form a battery pack. However, for battery packs with three or more rows, the process of forming a battery pack with multiple rows of battery packs has high requirements on the size offset and flatness of the two adjacent rows of battery packs. How to ensure the flatness of multiple rows of battery packs is a technical problem that needs to be solved urgently.

[0057] like Figures 1-5 An exemplary structural diagram of a battery stacking device provided in an embodiment of the present application is shown, and a battery stacking device provided in an embodiment of the present application comprises: a bottom plate 10, on which a plurality of first support plates 20 extending along a first direction are mounted, and the plurality of first support plates 20 are slidably connected to the bottom plate 10 along a second direction, and the first direction intersects with the second direction;

[0058] The first support plate 20 is provided with a first limiting groove 201 extending along the first direction, and the first limiting groove 201 is suitable for assembling a plurality of stacked batteries;

[0059] The first support plate 20 is provided with a clamping mechanism 30, and the clamping mechanism 30 is used to clamp and fix the multiple stacked batteries assembled on the first limiting groove 201 along the first direction;

[0060] A positioning mechanism is provided at the circumferential edge of the bottom plate 10 , and the positioning mechanism is suitable for assembling a battery group formed by a plurality of stacked batteries with a box body of a battery pack.

[0061] Specifically, Figure 1 , Figure 2 and Figure 4As shown in the figure, a plurality of first support plates 20 arranged in parallel are installed on the bottom plate 10. The first support plates 20 extend along the first direction, and the corresponding plurality of first support plates 20 are spaced apart along the second direction. A sliding connection is provided between the plurality of first support plates 20 and the bottom plate 10 along the second direction. Among them, a sliding rail 101 is provided on one of the opposite sides of the first support plate 20 and the bottom plate 10, and a sliding block is provided on the other, so as to realize the sliding connection between the first support plate 20 and the bottom plate 10. Exemplarily, a sliding rail 101 extending along the second direction is provided on the bottom plate 10, and sliding blocks are respectively provided at the bottom ends of the plurality of first support plates 20. The sliding blocks can be assembled into the sliding rail 101, and the plurality of first support plates 20 are slidably connected to the bottom plate 10 through the sliding blocks and the sliding rail 101, and the distance between adjacent two first support plates 20 can be adjusted; among them, there is at least one sliding rail 101 or a plurality of sliding rails 101 on the bottom plate 10. If there is one sliding rail 101, this sliding rail 101 can be provided in the middle of the bottom plate 10; if there are a plurality of sliding rails 101, the plurality of sliding rails 101 can be evenly or unevenly distributed along the second direction to improve the connection stability between the first support plate 20 and the bottom plate 10. Among them, the first direction and the second direction intersect, preferably perpendicularly. In the present application, the number of first support plates 20 can be set according to the size requirements of the battery pack. For example, the number of first support plates 20 can be 2, 3, 4, 5, etc.

[0062] As Figure 1 , Figure 2 and Figure 4 shown, a first limiting groove 201 extending along the first direction is formed on the first support plate 20. The first limiting groove 201 can be a pole limiting groove for limiting and fixing the poles of the battery, so that the battery can be placed upside down on the first support plate 20. A plurality of batteries can be stacked in the first limiting groove 201 of the first support plate 20. The alignment flatness of the plurality of batteries is high, and the flatness of the bottom of the battery is high, and the flatness of the side is good.

[0063] As Figure 1 , Figure 2 and Figure 4 shown, pressing mechanisms 30 are provided on both sides of the first support plate 20 along the first direction. After a plurality of batteries are stacked in the first limiting groove 201, the pressing mechanisms 30 are used to press and restrain the plurality of batteries along the first direction, so that the plurality of batteries are stacked to form a battery pack with a preset size. Therefore, through the pressing mechanisms 30, it can be ensured that the sizes of any two adjacent battery packs are the same, the flatness is high, and the alignment degree is good. Then, the plurality of first support plates 20 move on the bottom plate 10 along the second direction to adjust the positions of the plurality of first support plates 20 along the second direction, and further, the distance between adjacent two battery packs can be adjusted according to actual needs to meet the assembly requirements of the battery pack.

[0064] As Figure 1 , Figure 2 and Figure 4As shown, a positioning mechanism is provided at the circumferential edge position of the bottom plate 10. After multiple batteries are stacked in the first limiting groove 201 and the battery pack is pressed to a preset size by the pressing mechanism 30, and after the distance between adjacent two battery packs is adjusted by the movement of the first support plate 20 on the bottom plate 10, the box body is inverted onto the positioning mechanism of the bottom plate 10, so that multiple first support plates 20, multiple batteries on the first support plate 20, and the pressing mechanism 30 are located inside the box body, realizing the relative fixation of the box body with the battery pack and the liquid cooling plate. Then, the box body is flipped to realize the inversion of multiple rows of battery packs into the box body, completing the operation of stacking the battery packs into the box. Among them, the top end of the box body is an open end, and avoidance positions are provided on two side walls along the first direction to facilitate the release of the pressing restraint on the multiple rows of battery packs loaded into the box body.

[0065] The battery stacking device provided by the embodiment of the present application has a simple structure, is easy to operate and implement, can improve the alignment flatness of multiple batteries, and realizes the operation of inverting multiple rows of battery packs into the box, ensuring the stacking accuracy of multiple rows of battery packs during the process of entering the box, making the alignment degree of multiple rows of battery packs high, and improving the stacking efficiency of multiple rows of battery packs.

[0066] In the present application, the specific type of the battery is not particularly limited. For example, the battery can be a lithium battery. Handles 104 can be provided in the four surrounding directions of the bottom plate 10 to facilitate the installation operation of the bottom plate 10.

[0067] In some embodiments, such as Figure 1 、 Figure 2 and Figure 4 As shown, the positioning mechanism includes positioning members 40 provided at the circumferential edge of the bottom plate 10. A positioning groove 401 is provided on the positioning member 40, and the box body is connected to the positioning member 40 in a plug-in fit manner through the positioning groove 401.

[0068] Specifically, the positioning mechanism includes three or four positioning members 40. The positioning members 40 are provided at the circumferential edge position of the bottom plate 10. Multiple positioning members 40 are distributed in the corner area of the bottom plate 10 along the four surrounding directions. Two of the positioning members 40 are distributed on the same side of the bottom plate 10 in the first direction, and the other one or two positioning members 40 are located on the other side of the bottom plate 10, and the two positioning members 40 on the same side are spaced apart in the second direction. Exemplarily, if the positioning mechanism includes four positioning members 40, the four positioning members 40 are symmetrically arranged along the first direction and the second direction respectively.

[0069] A positioning groove 401 facing the bottom plate 10 side is provided on the positioning member 40. The corner area of the side wall of the box body can be inserted into the positioning groove 401 to realize the plug-in fit connection between the box body and multiple positioning members 40. Among them, the positioning member 40 and the bottom plate 10 can be connected by means such as screwing, riveting, sliding connection, and welding.

[0070] In some embodiments, at least a part of the positioning member 40 is slidably connected to the bottom plate 10 along the first direction.

[0071] Specifically, two positioning members 40 located on the same side of the bottom plate 10 along the first direction are slidably connected to the bottom plate 10 to adapt to boxes of different sizes, thereby meeting the tooling requirements of battery packs of different sizes. There are various implementation manners for the sliding connection between the positioning member 40 and the bottom plate 10. Exemplarily, for example, a chute extending along the first direction is provided on the bottom plate 10, a bolt is slidably fixed at the bottom end of the positioning member 40, and the bolt can slide in the chute and is fixedly connected to a nut through the chute to realize the movement and limitation of the positioning member 40 on the bottom plate 10; again, for example, a plurality of limiting holes 702 are provided on the bottom plate 10 along the first direction, a plug pin 901 is slidably arranged on the positioning member 40, and the plug pin 901 can be inserted into the limiting hole 702 to realize the movement and limitation of the positioning member 40 on the bottom plate 10.

[0072] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 shown, the pressing mechanism 30 includes a first pressing plate 301 and a second pressing plate 302. The first pressing plate 301 and the second pressing plate 302 are respectively arranged on two sides of the first support plate 20 along the first direction, and at least one of the first pressing plate 301 and the second pressing plate 302 is slidably connected to the first support plate 20.

[0073] Specifically, the pressing mechanism 30 includes a first pressing plate 301 and a second pressing plate 302 distributed on two sides of the first support plate 20 along the first direction. Among them, the first pressing plate 301 can be fixedly arranged on one side of the first support plate 20, and the second pressing plate 302 is slidably arranged on the other side of the first support plate 20; or the first pressing plate 301 and the second pressing plate 302 are respectively slidably arranged on two sides of the first support plate 20. Among them, a slide rail 101 extending along the first direction can be arranged on the first support plate 20, and the first pressing plate 301 or the second pressing plate 302 is connected to the slide rail 101 on the first support plate 20 through a slider. By moving the first pressing plate 301 or / and the second pressing plate 302 along the first direction, a plurality of batteries installed on the first support plate 20 are pressed and fixed, ensuring the alignment flatness of the plurality of batteries.

[0074] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 shown, the pressing mechanism 30 further includes a first driving part 303, and the pressing plate slidably connected to the first support plate 20 is fixedly connected to the first driving part 303 to drive the corresponding pressing plate to linearly move along the first direction.

[0075] Specifically, the first driving part 303 is fixedly connected to the first pressing plate 301 or the second pressing plate 302, and can drive the first pressing plate 301 or the second pressing plate 302 to linearly move in the first direction, thereby realizing the pressing and fixing of multiple batteries installed on the multiple first support plates 20, and can meet the pressing and fixing requirements for battery packs of different sizes. Among them, the first driving part 303 can be a lead screw motor, a cylinder or an electric push rod, etc. Among them, the first driving part 303 is fixedly arranged on the first support plate 20, and the first driving part 303 is detachably connected to the first support plate 20 by means of screwing, riveting, etc.

[0076] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 shown, a fixing mechanism 50 is arranged on the bottom plate 10 between two adjacent first support plates 20, and the fixing mechanism 50 is used to fix the liquid cooling plate in the first direction.

[0077] Specifically, there is a fixing mechanism 50 between any two adjacent first support plates 20. The fixing mechanism 50 is distributed on both sides of the bottom plate 10 in the first direction, and the two side walls of the liquid cooling plate in the first direction are fixed by the fixing mechanism 50. That is, a liquid cooling plate is fixed between two adjacent rows of battery packs by the fixing mechanism 50, and the relative positions of two adjacent rows of battery packs and the liquid cooling plate can be adjusted by the sliding of the first support plate 20 on the bottom plate 10, so that a row of battery packs, the liquid cooling plate and another row of battery packs are closely adjacent to each other in the second direction, ensuring the stacking effect of the battery packs and improving the packing effect of the battery pack.

[0078] In some embodiments, such as Figure 4 and Figure 5 shown, the fixing mechanism 50 includes a first fixing part 510 and a second fixing part 520 distributed on the bottom plate 10 in the first direction.

[0080] In some embodiments, such as Figure 4 and Figure 5As shown, the fixing mechanism 50 further includes a second support plate 60. The second support plate 60 is slidably connected to the bottom plate 10 along a second direction. The first fixing member 510 and the second fixing member 520 are disposed on the second support plate 60, and at least one of the first fixing member 510 and the second fixing member 520 is slidably connected to the second support plate 60 along a first direction.

[0081] Specifically, the sliding connection manner between the second support plate 60 and the bottom plate 10 is the same as that between the first support plate 20 and the bottom plate 10. By sliding the second support plate 60 on the bottom plate 10, the position of the liquid cooling plate along the second direction can be adjusted, so as to more conveniently adjust the relative positions of two adjacent rows of battery packs and the liquid cooling plate, further improve the stacking effect of the battery packs and the liquid cooling plate, and improve the packing effect of the battery pack.

[0082] Wherein, one of the first fixing member 510 and the second fixing member 520 is fixedly connected to the second support plate 60, and the other fixing member is slidably connected to the second support plate 60; or, both the first fixing member 510 and the second fixing member 520 are slidably connected to the second support plate 60, so that the moving position of the fixing member on the second support plate 60 can be adjusted to meet the tooling requirements of liquid cooling plates of different sizes, and can adapt to the tooling requirements of a preset size of battery packs, thereby improving the application range of the battery stacking device.

[0085] Specifically, the moving position of the first fixing member 510 or the second fixing member 520 on the second support plate 60 along the first direction is limited by the first limiting member 70, so as to meet the limiting and fixing of liquid cooling plates of different sizes and have better adaptability to the size of the battery packs.

[0086] In some embodiments, as Figure 4 and Figure 5As shown, the first limiting member 70 includes a limiting pin 701 and a plurality of limiting holes 702. Among them, the plurality of limiting holes 702 are distributed in a first direction on the second support plate 60.

[0087] Specifically, a plurality of limiting holes 702 are arranged at intervals in the first direction on the second support plate 60.

In this example, the first limiting member 70 can limit the moving position of the first fixing member 510 and / or the second fixing member 520 in the first direction on the second support plate 60. Among them, the limiting pin 701 can be a bolt, and the corresponding limiting hole 702 is a threaded hole, and the bolt can be assembled into the threaded hole to make the fixation of the first fixing member 510 and / or the second fixing member 520 to the second support plate 60 more firm.

[0088] In some embodiments, as Figure 4 and Figure 5 shown, support rods 530 are respectively arranged on the first fixing member 510 and the second fixing member 520. The support rod 530 on the first fixing member 510 and the support rod 530 on the second fixing member 520 respectively abut against the two end faces of the liquid cooling plate along the first direction.

[0089] Specifically, support rods 530 are respectively arranged on one side of the first fixing member 510 and the second fixing member 520 away from each other.
