[0032] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0033] According to an embodiment of the present invention, a battery module stacking structure is provided, comprising: multiple battery modules 2, stacked sequentially in a vertical direction; a fixing component, wherein each battery module 2 has at least two fixing brackets spaced apart in a horizontal direction on its periphery, and adjacent fixing brackets are connected by a second telescopic member 13; the fixing component includes fixing brackets; the fixing brackets include a first telescopic member 1, a first clamping part 3, and a second clamping part 4; the first clamping part 3 and the second clamping part 4 are respectively disposed at both ends of the first telescopic member 1; the first clamping part 3 and the second clamping part 4 are respectively clamped on the upper and lower sides of the battery module 2, and the first telescopic member 1 is connected to the battery module 2; the first clamping part 3 and the second clamping part 4 of two adjacent fixing brackets are connected.

[0034] It should be noted that the upper and lower adjacent fixed components are set one-to-one; the second telescopic component 13 is adjustable in the horizontal direction; the first telescopic component 1 is adjustable in the vertical direction.

[0035] In this embodiment, a fixing component is provided around the battery module 2, and adjacent battery modules 2 are connected by the fixing component. First, according to the length or width of the battery module 2, the distance between the two fixing brackets is adjusted by the second telescopic member 13 to adapt to the battery module 2. Then, according to the height of the battery module 2, the telescopic length of the first telescopic member 1 is adjusted so that a clamping space adapted to the height of the battery module 2 is formed between the first clamping part 3 and the second clamping part 4, so that the first clamping part 3 and the second clamping part 4 can be clamped on the upper and lower sides of the battery module 2 respectively, and the battery module 2 is fixed to the first telescopic member 1 to improve stability. Then, multiple battery modules 2 are sequentially... The stacking process connects the second clamping part 4 of the upper-layer fixing bracket with the first clamping part 3 of the lower-layer fixing bracket, thereby sequentially completing the stacking of multiple battery modules 2. Since the first clamping part 3 and the second clamping part 4 are located on the upper and lower sides of the battery module 2, a gap is formed between two adjacent battery modules 2 when multiple battery modules 2 are stacked, which facilitates heat dissipation of the battery modules 2. The distance between the first clamping part 3 and the second clamping part 4 is adjusted by the first telescopic member 1, and the distance between two adjacent fixing brackets in the same fixing component is adjusted by the second telescopic member 13, so as to adapt to battery modules 2 with different heights, widths and lengths, with a wide range of applications and improved stability when fixing battery modules 2.

[0036] In one embodiment, such as Figure 1 As shown, each fixed bracket on the side wall of the battery module 2 is provided with a rivet 5; the rivet 5 passes through the first telescopic member 1 and is fixedly connected to the first telescopic member 1 by the first nut 6.

[0037] In this embodiment, rivets 5 are provided on the side wall of the battery module 2 corresponding to the fixed bracket. During connection, the rivets 5 are passed through the first telescopic member 1 and fixed by the first nut 6, which facilitates installation and disassembly.

[0038] In one embodiment, such as Figures 2 to 6 As shown, the first telescopic member 1 includes a first vertical plate 101 and a second vertical plate 102; the second vertical plate 102 is slidably connected to the first vertical plate 101 in the vertical direction; a first clamping part 3 is disposed on the first vertical plate 101, and a second clamping part 4 is disposed on the second vertical plate 102; a first connecting groove 7 is provided on the first vertical plate 101 in the vertical direction, and a second connecting groove 8 is provided on the second vertical plate 102 corresponding to the first connecting groove 7; a rivet 5 passes through the first connecting groove 7 and the second connecting groove 8.

[0039] It should be noted that the first connecting groove 7 and the second connecting groove 8 at least partially overlap; the first vertical plate 101 and the second vertical plate 102 are parallel.

[0040] In this embodiment, the first telescopic member 1 is composed of a first vertical plate and a second vertical plate 102 slidably connected. At the same time, the first vertical plate 101 and the second vertical plate 102 correspond to the first connecting groove 7 and the second connecting groove 8, respectively. According to the height of the battery module 2, the first vertical plate 101 and the second vertical plate 102 are adjusted to slide relative to each other until the first clamping part 3 and the second clamping part 4 are adapted to clamp the battery module 2. Then, the rivet 5 passes through the first connecting groove 7 and the second connecting groove 8 at the same time, that is, through the overlapping part of the first connecting groove 7 and the second connecting groove 8. Then, the first nut 6 is used for fixing, which fixes the first telescopic member 1 to the side wall of the battery module 2, while preventing relative sliding between the first vertical plate 101 and the second vertical plate 102.

[0041] In one embodiment, such as Figure 2 and Figure 3 As shown, the bottom end of the first vertical plate 101 is provided with a first mounting cavity 9 along the vertical direction, and the top end of the second vertical plate 102 is adapted to be slidably inserted into the first mounting cavity 9.

[0042] It should be noted that the first clamping part 3 is located at the top of the first vertical plate 101, and the second clamping part 4 is located at the bottom of the second vertical plate 102.

[0043] In this embodiment, the stability during the adjustment process is improved by providing a first mounting cavity 9 at the bottom of the first vertical plate 101 and slidingly connecting it with the second vertical plate 102.

[0044] Specifically, the first connecting groove 7 includes a first groove body and a second groove body. The first groove body is located on the side of the first mounting cavity 9 facing the battery module 2 and is connected to the first mounting cavity 9. The second groove body is located on the side of the first mounting cavity 9 away from the battery module and is connected to the first mounting cavity 9. The width of the second groove body is adapted to the first nut 6 and is greater than the width of the second connecting groove 8. When the first nut 6 is connected to the rivet 5, the first nut 6 can be embedded in the second groove body and abut against the second vertical plate 102, reducing the space occupied by the first nut 6 and improving the space utilization rate.

[0045] In one embodiment, such as Figures 1 to 6 As shown, the top of the first clamping part 3 is provided with a limiting member 10, and the bottom of the second clamping part 4 is provided with a limiting hole that is adapted to the limiting member 10.

[0046] In this embodiment, by setting mutually compatible limiting members 10 and limiting holes, when stacking battery modules 2, the limiting holes of the second clamping part 4 of the upper layer are aligned with the limiting members 10 of the first clamping part 3 of the lower layer for positioning and installation, which facilitates installation and improves work efficiency during stacking.

[0047] In one embodiment, such as Figure 2 , Figure 4 and Figure 6 As shown, the fixing assembly also includes a second nut 12, and the second clamping part 4 is provided with an operating cavity 11. The limiting hole communicates with the operating cavity 11. The limiting member 10 is a first screw. The first screw extends into the operating cavity 11 and is threadedly connected to the second nut 12.

[0048] In this embodiment, the limiting member 10 is a first screw. During installation, the first screw can pass through the limiting hole and extend into the operating cavity 11. The space of the operating cavity 11 is used to tighten the second nut 12 onto the first screw for fixation, thereby improving stability.

[0049] In one embodiment, such as Figure 1 and Figure 2 As shown, there are two fixed supports, which are symmetrically arranged in the horizontal direction.

[0050] In this embodiment, two fixing brackets are provided, which can be set in the width direction of the battery module 2. This can not only be adjusted to match the width of the battery module 2, improving the stability during fixing, but also avoid waste and inconvenience caused by setting too many fixing brackets, thus improving stability and applicability.

[0051] In one embodiment, such as Figures 2 to 6 As shown, the second telescopic member 13 includes a first horizontal plate 1301 and a second horizontal plate 1302. The first horizontal plate 1301 and the second horizontal plate 1302 are slidably connected in the horizontal direction. The first horizontal plate 1301 is fixedly connected to one of the two fixed brackets, and the second horizontal plate 1302 is fixedly connected to the other of the two fixed brackets.

[0052] In this embodiment, the second telescopic member 13 adopts a first horizontal plate 1301 and a second horizontal plate 1302 that slide and cooperate with each other to improve stability. At the same time, the first horizontal plate 1301 and the second horizontal plate 1302 are respectively connected to two fixed brackets to adjust the distance between the two fixed brackets to adapt to the length or width of the battery module 2.

[0053] In one embodiment, such as Figures 2 to 6 As shown, the fixing assembly also includes a second screw 17. A second mounting cavity 14 is provided on the first horizontal plate 1301 corresponding to the second horizontal plate 1302, and the second horizontal plate 1302 is adapted to be slidably inserted into the second mounting cavity 14. A plurality of first connecting holes 15 are provided on the first horizontal plate 1301 corresponding to the second horizontal plate 1302, and the plurality of first connecting holes 15 are spaced apart along the length direction of the second mounting cavity 14. A second connecting hole 16 is provided on the second horizontal plate 1302 corresponding to the first connecting holes 15. The second screw 17 passes through the first connecting hole 15 and the second connecting hole 16.

[0054] It should be noted that the first connecting hole 15 is connected to the second mounting cavity 14; both the first connecting hole 15 and the second connecting hole 16 are adapted to the second screw 17.

[0055] In this embodiment, a second mounting cavity 14 adapted to the second horizontal plate 1302 is provided on the first horizontal plate 1301, so that the second horizontal plate 1302 is adapted to slide in the second mounting cavity 14 to adjust the distance between the two fixed brackets. When the two fixed brackets are adjusted to an appropriate distance, the second connecting hole 16 is aligned with the first connecting hole 15 at a predetermined position. Then, the second screw 17 is passed through the first connecting hole 15 and the second connecting hole 16 in sequence for fixing, so as to avoid the first horizontal plate 1301 and the second horizontal plate 1302 sliding relative to each other during use and improve stability.

[0056] Specifically, the side wall of the battery module 2 is provided with a threaded hole corresponding to the second screw 17. The second screw 17 passes through the first connecting hole 15 and the second connecting hole 16 in sequence and is threadedly connected to the threaded hole, which further improves stability.

[0057] Specifically, the second screw 17 is a crimping screw, which facilitates material sourcing and installation.

[0058] Specifically, the first screw is a crimping screw, which is convenient for material sourcing and installation.

[0059] In one embodiment, two sets of fixing components are provided, and the two sets of fixing components are respectively provided on both sides of the battery module 2 along its length direction.

[0060] In this embodiment, by providing fixing components on both sides of each battery module 2 along its length, the stability of the battery modules 2 during stacking is improved.

[0061] Specifically, such as Figure 1 and Figure 2 As shown, the first horizontal plate 1301 and the second horizontal plate 1302 are integrally formed with the first vertical plate 101 of the two fixed brackets to avoid affecting the extension and retraction adjustment of the first telescopic component 1.

[0062] Specifically, such as Figures 1 to 6 As shown, the first clamping part 3 is integrally formed with the first vertical plate 101 and is formed by bending the end of the first vertical plate 101 by 90 degrees.

[0063] Specifically, such as Figures 1 to 6 As shown, the second clamping part 4 is integrally formed with the second vertical plate 102, and the end of the second vertical plate 102 is bent to form a rectangular structure, forming an operating cavity 11.

[0064] The specific installation process of the battery module stacking structure provided in this embodiment is as follows: First, two sets of fixing components are used, each set including two fixing brackets. The two sets of fixing components are symmetrically arranged at both ends of the battery module 2. According to the width of the battery module 2, it is slid relative to the first horizontal plate 1301 and the second horizontal plate 1302 to an appropriate position and then fixed with the second screw 17. Next, according to the height of the battery module 2, it is slid relative to the first vertical plate 101 and the second vertical plate 102, so that the first clamping part 3 and the second clamping part 4 form a connection with the battery module 2. The highly adaptable clamping space allows the first clamping part 3 and the second clamping part 4 to be clamped on the upper and lower sides of the battery module 2, respectively. At the same time, the rivets 5 on the side wall of the battery module 2 are passed through the first connecting groove 7 and the second connecting groove 8 and then fixed with the first nut 6. Then, multiple battery modules 2 are stacked in sequence, so that the limiting hole of the second clamping part 4 of the upper layer is aligned and connected with the limiting member 10 of the first clamping part 3 of the lower layer. Then, the first clamping part 3 and the second clamping part 4 are fixed with the second nut 12, thereby completing the stacking of multiple battery modules 2 in sequence.
