[0014] Technical solution ten and its related embodiments provide an energy storage module, which adopts a slidable supporting device described in any one of technical solutions one to nine.

[0015] From the above description of the utility model and its preferred embodiments, it can be seen that, compared with the prior art, the technical solution of the utility model and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0016] In technical solution one, a sliding assembly is installed on the base of the supporting device, so that the supporting device can slide along the first direction with little resistance. When the supporting device supports the energy storage cell to form an energy storage module, the energy storage module can be easily pushed on the guide rail of the container, thereby facilitating installation and maintenance; wherein, the mounting seat and the connecting portion are detachably fixedly connected, so that when the roller is damaged, the sliding assembly can be disassembled as a whole, thereby facilitating replacement.

[0017] In the second technical solution, the connection part is located in the support frame, and the mounting seat is detachably fixed to the connection part through the opening so that the roller part is located in the support frame, so that only part of the roller is exposed from the support frame, and the other part is located in the support frame, thereby utilizing the space in the height direction of the support frame, so that the supporting device as a whole still has a relatively small height. In practical applications, it is found that when the roller part is located in the support frame, it is extremely difficult to replace the roller if it is damaged. In this technical solution, the mounting seat is detachably fixed to the connection part, so that when the roller is damaged, the sliding assembly can be disassembled as a whole through the opening of the bottom wall, thereby facilitating replacement.

[0018] In technical solution three, the cooperation between the top abutting surface and the abutting surface ensures that as long as the heights of the connecting parts are kept consistent, the bottom ends of the rollers can be basically located on the same plane, thus avoiding the influence of the inclination of the supporting device on the energy storage module; wherein, the connecting part is locked with the mounting seat for easy disassembly and assembly.

[0019] In technical solution four, a first through hole suitable for the upper part of the roller to extend out is opened on the mounting seat, and a second through hole corresponding to the first through hole is provided on the connecting wall. On the one hand, the sliding assembly can be pre-positioned during the installation process by passing the upper part of the roller through the second through hole to lock the connecting part and the mounting seat. On the other hand, the space inside the support frame (the gap between the connecting wall and the top wall) and the space of the mounting seat can be further utilized, so that the overall height of the sliding assembly is small, and the height and volume of the supporting device can be further reduced.

[0020] In technical solution five, the structure of the mounting seat is simple and easy to process. In practical applications, the connecting shaft can be passed through the roller first, and then the two ends of the connecting shaft can be inserted into the limit grooves and welded to the mounting plate. The process is simple and the cost is low.

[0021] In technical solution six, the bottom of the limit groove is parallel to the first direction and the second direction, that is, the limit groove is a square groove. Compared with the arc groove, it has lower cost and is easier to ensure that the upper ends of each connecting shaft are in the same plane, thereby ensuring that the bottom ends of each roller are in the same plane.

[0022] In Technical Solution 7, when the energy storage module is in a static state, the entire energy storage module is supported by rollers, and the force of the rollers is transmitted upward to the mounting plate, and then indirectly transmitted to the connecting part. In Technical Solution 6, the connecting part is welded to the side wall and the top wall, so that the entire connecting part is welded to the side wall and the top wall, and the structure is more stable and not easy to break.

[0023] In technical solution eight, the connecting part is integrally formed and provided with an abutting wall parallel to and opposite to the top wall. The abutting wall is formed at the free end of the connecting part and welded to the top wall, so that when the connecting part is subjected to force, it can support the top wall of the supporting frame upward and is not easy to break; the connecting parts on the two supporting frames are symmetrically arranged, so that when the supporting device supports the energy storage cells to form an energy storage module, the entire energy storage module is subjected to more balanced force.

[0024] In technical solution nine, the lifting part is welded to the side wall, a first hanging hole is formed on the side wall, and a second hanging hole is formed on the lifting part. Therefore, when the energy storage module is lifted, the first hanging hole and the second hanging hole form a reinforcing structure to avoid deformation of the side wall. Especially when the roller is damaged, the entire energy storage module can be lifted through the lifting structure through the first hanging hole and the second hanging hole, and the sliding assembly can be replaced from the bottom of the support frame.

[0025] Technical solution ten has the technical advantages of any one of technical solutions one to nine. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] See also Figure 1-9 , Figure 1-9 A slidable supporting device 100 is shown for use in an energy storage module. Figure 1 In this embodiment, the energy storage module includes two battery packs arranged along a first direction, each battery pack includes N energy storage batteries 70 arranged along a second direction perpendicular to the first direction and extending along the first direction, the length direction of the energy storage battery 70 is the first direction, and the width direction of the energy storage battery 70 is the second direction, Figure 1 In the embodiment, the first direction is the front-to-back direction, and the second direction is the left-to-right direction. N is a positive integer greater than 1. In the embodiment, N is 4.

[0044] See also Figure 2-9 The bottom bracket 10 extends along the first direction, and support frames 20 are respectively provided on both sides thereof along the second direction. Each support frame 20 is provided with a bottom wall 21, a top wall 22 opposite to the bottom wall 21, and a side wall 23 connecting the bottom wall 21 and the top wall 22. The bottom wall 21 is provided with at least one opening 211 along the first direction. In this embodiment, the bottom wall 21 of each bracket is provided with at least two openings 211 along the first direction. Figure 2 There are four openings 211 in total. A connecting portion 30 facing the opening 211 is provided in the support frame 20. The connecting portion 30 is welded to the side wall 23 and the top wall 22. Figure 6 and Fig. 9 In the figure, the connecting portion 30 is in an inverted "J" shape as a whole. The connecting portion 30 is integrally formed and provided with an abutting wall 31 parallel to and opposite to the top wall 22. The abutting wall 31 is formed at the free end of the connecting portion 30 and welded to the top wall 22. The connecting portion 30 is provided with a connecting wall 32 parallel to and opposite to the top wall 22. A gap is formed between the connecting wall 32 and the top wall 22. An abutting surface 321 is formed on the lower surface of the connecting wall 32, that is, the connecting portion 30 is provided with an abutting surface 321 facing the opening 211. The length direction of the connecting wall 32 is the first direction. A second through hole 322 is provided in the middle of the connecting wall 32. Nuts 323 are protruding upwards on the upper surface of the connecting wall 32 at both sides of the second through hole 322. A threaded hole corresponding to the nut 323 is provided on the connecting wall 32. The threaded hole is connected to the inner cavity of the nut 323 to form a first threaded hole 324.

[0045] Still see Figure 6 and Fig. 9The number of sliding components is equal to and corresponds to the connecting part 30, and it includes a mounting seat 40 and a roller 50. The roller 50 is rotatably mounted on the mounting seat 40 around an axis extending along the second direction. The mounting seat 40 is suitable for passing through the opening 211 and being detachably fixed to the connecting part 30 so that the roller 50 is partially located in the support frame 20 and is suitable for sliding along the first direction. Specifically, the mounting seat 40 includes a mounting plate 41 and a connecting shaft 42. The upper surface of the mounting plate 41 forms a top abutting surface 411 that abuts against the abutting surface 321. The mounting plate 41 extends along the first direction, and a first through hole 412 is provided in the middle thereof, which is suitable for the upper part of the roller 50 to extend out. The first through hole 412 corresponds to the second through hole 322. The mounting plate 41 has second threaded holes 413 respectively provided on both sides of the first through hole 412 along the first direction, and the second threaded holes 413 correspond to the first threaded holes 324. Therefore, two bolts can be passed through the second threaded holes 413 and the first threaded holes 324 to lock the mounting plate 41 and the connecting wall 32, thereby locking the mounting seat 40 and the connecting portion 30. The mounting plate 41 has limit grooves 414 with downward openings on both sides of the first through hole 412 along the second direction; the roller 50 is sleeved on the connecting shaft 42, and the connecting shaft 42 extends along the second direction; the two ends of the connecting shaft 42 are inserted into the limit grooves 414 and welded to the mounting plate 41.

[0046] In this embodiment, a sliding assembly is installed on the base 10 of the supporting device 100, so that the supporting device 100 can slide along the first direction with small resistance. When the supporting device 100 supports the energy storage cell 70 to form an energy storage module, the energy storage module is easy to be pushed on the guide rail of the container, thereby facilitating installation and maintenance; wherein, the connecting portion 30 is located in the support frame 20, and the mounting seat 40 is detachably fixed to the connecting portion 30 through the opening 211 so that the roller 50 is partially located in the support frame 20, so that only a portion of the roller 50 is exposed from the support frame 20, and the other portion is located in the support frame, thereby utilizing the space in the height direction of the support frame 20, so that the supporting device 100 as a whole still has a relatively small height. Furthermore, a first through hole 412 suitable for the upper part of the roller 50 to extend out is opened on the mounting seat 40, and a second through hole 322 corresponding to the first through hole 412 is provided on the connecting wall 32. On the one hand, the sliding assembly can be pre-positioned during the installation process by passing the upper part of the roller 50 through the second through hole 322, thereby locking the connecting wall 32 and the mounting plate 41. On the other hand, the space inside the support frame 20 (the gap between the connecting wall 32 and the top wall 22) and the space of the mounting seat 40 can be further utilized, so that the overall height of the sliding assembly is small, and the height and volume of the supporting device 100 can be further reduced.

[0047] In practical applications, it is found that when the roller 50 is partially located in the support frame 20, it is extremely difficult to replace the roller 50 if it is damaged. In this embodiment, the mounting seat 40 is detachably fixed to the connecting portion 30, so that when the roller 50 is damaged, the sliding assembly can be disassembled as a whole through the opening 211 of the bottom wall 21, thereby facilitating replacement. The cooperation between the top abutting surface 411 and the abutting surface 321 ensures that as long as the height of each connecting portion 30 is consistent, the bottom ends of each roller 50 can be basically located on the same plane, thereby avoiding the influence of the tilt of the supporting device 100 on the energy storage module.

[0048] Fig. 9 In the embodiment, the bottom of the limiting groove 414 is parallel to the first direction and the second direction, that is, the limiting groove 414 is a square groove, which has lower cost than an arc groove and is easier to ensure that the upper ends of each connecting shaft 42 are located in the same plane, thereby ensuring that the bottom ends of each roller 50 are located in the same plane.

[0049] When the energy storage module is in a static state, the entire energy storage module is supported by the roller 50, and the force of the roller 50 is indirectly transmitted upward to the connecting portion 30 through the connecting shaft 42 and the mounting plate 41. In this embodiment, the connecting portion 30 is welded to the side wall 23 and the top wall 22, so that the connecting portion 30 is welded to the side wall 23 and the top wall 22 as a whole, and the structure is more stable and not easy to break. The connecting portion 30 is integrally formed and is provided with an abutting wall 31 parallel to and opposite to the top wall 22. The abutting wall 31 is formed at the free end of the connecting portion 30 and is welded to the top wall 22, so that the connecting portion 30 can support the top wall 22 of the support frame 20 upward when subjected to force, and is not easy to break. In this embodiment, the connecting portions 30 on the two support frames 20 are symmetrically arranged, so that when the supporting device 100 supports the energy storage battery cell 70, the entire energy storage module is subjected to more balanced force.

[0050] A plurality of first hanging holes 231 are arranged on the side wall 23 along the first direction, the number of the lifting parts 60 is equal to the number of the first hanging holes 231 and corresponds one to one, the lifting parts 60 are welded to the inner surface of the side wall 23 and are provided with second hanging holes 61 corresponding to the first hanging holes 231, therefore, when the energy storage module is lifted, the first hanging holes 231 and the second hanging holes 61 form a reinforcement structure to avoid deformation of the side wall 23; especially when the roller 50 is damaged, the entire energy storage module can be lifted through the lifting structure through the first hanging holes 231 and the second hanging holes 61, and the sliding assembly can be replaced from the bottom of the support frame 20.

[0051] This embodiment also provides an energy storage module. Figure 1 , which adopts the supporting device 100 in Example 1 and has the same advantages as Example 1.

[0052] It should be understood that in actual applications, the energy storage module will also include electrical components such as an outer cover, a battery cell group, a wiring copper bus, a wiring terminal, a safety switch, a sensor, etc. The supporting device 100 is fixedly connected to the outer cover to form a shell that can accommodate the battery cell group. The battery cell groups can be connected in series through the wiring copper bus and then electrically connected to external devices through the wiring terminal. This part belongs to the existing technology and will not be repeated here.

Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
