Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] This utility model discloses a battery module, referenced... Figure 1 , Figure 4 , Figure 10 and Figure 11As shown, the battery module in this embodiment is used for energy storage power and is installed inside the energy storage housing 100 of the energy storage power. The battery module includes multiple individual batteries 200, a first bracket 300 and a second bracket 400. The first bracket 300 and the second bracket 400 are installed at both ends of the multiple individual batteries 200. The first bracket 300 is provided with a first positioning post 310 and multiple first snap-fit ​​structures 320. The first positioning post 310 is located in the middle of the multiple first snap-fit ​​structures 320. The second bracket 400 is provided with a second positioning post 410 and multiple second snap-fit ​​structures 420. The multiple first snap-fit ​​structures 320 and the multiple second snap-fit ​​structures 420 are snap-fitted one-to-one. The first positioning post 310 and the second positioning post 410 are positioned and connected. The first snap-fit ​​structure 320 or the second snap-fit ​​structure 420 is provided with a limiting structure, which restricts the rotation of the first snap-fit ​​structure 320 relative to the second snap-fit ​​structure 420; and / or, the first positioning post 310 and the second positioning post 410 are anti-rotationally connected to prevent the first positioning post 310 and the second positioning post 410 from rotating. It is understood that in the actual assembly process, after multiple individual battery cells 200 are installed on the second bracket 400, the first bracket 300 is installed on the second bracket 400, the first positioning post 310 and the second positioning post 410 are positioned and connected, and the multiple first snap-fit ​​structures 320 and the multiple second snap-fit ​​structures 420 are snapped together one-to-one, achieving fixation through inner positioning connection and outer snap-fit, which is convenient for assembly, and the first bracket 300 and the second bracket 400 are subjected to relatively balanced forces, which is beneficial to improving the protection of the multiple individual battery cells 200. Meanwhile, a limiting structure is provided on the first snap-fit ​​structure 320 or the second snap-fit ​​structure 420 to restrict the rotation of the first snap-fit ​​structure 320 relative to the second snap-fit ​​structure 420; and / or, the first positioning post 310 and the second positioning post 410 are anti-rotationally connected to prevent the first positioning post 310 and the second positioning post 410 from rotating. The limiting structure restricts relative rotation between the first snap-fit ​​structure 320 and the second snap-fit ​​structure 420, and the anti-rotation connection restricts relative rotation between the first positioning post 310 and the second positioning post 410, resulting in strong anti-rotation capability of the first bracket 300 and the second bracket 400, which can better protect the individual battery 200.

[0038] Optionally, the fastener passes through the first positioning post 310 and connects to the second positioning post 410. This improves the connection stability between the first bracket 300 and the second bracket 400. The fastener can be selected from structures such as fixing pins or screws, depending on actual needs.

[0039] Optional, see reference Figures 10-11 As shown, the first positioning post 310 is also provided with a plurality of first reinforcing ribs 312, and the second positioning post 410 is also provided with a plurality of second reinforcing ribs 413. This can improve the strength of the first positioning post 310 and the second positioning post 410, thereby indirectly improving the connection stability of the first bracket 300 and the second bracket 400.

[0040] Optional, see reference Figures 10-11 As shown, the first bracket 300 is provided with a first snap-fit ​​groove 350, and the second bracket 400 is provided with a second snap-fit ​​groove 450. The two ends of the single battery 200 are respectively snapped into the first snap-fit ​​groove 350 and the second snap-fit ​​groove 450. This enhances the fixing effect of the first bracket 300 and the second bracket 400 on the single battery 200, thereby ensuring the protection effect of the single battery 200.

[0041] Optional, see reference Figure 4 , Figures 7-9 As shown, the plurality of first snap-fit ​​structures 320 include a plurality of first outer snap-fit ​​portions 321 and a plurality of first inner snap-fit ​​portions 322, the first outer snap-fit ​​portions 321 and the first inner snap-fit ​​portions 322 being arranged alternately; the plurality of second snap-fit ​​structures 420 include a plurality of second outer snap-fit ​​portions 421 and a plurality of second inner snap-fit ​​portions 422, the second outer snap-fit ​​portions 421 and the second inner snap-fit ​​portions 422 being arranged alternately, the plurality of first outer snap-fit ​​portions 321 and the plurality of second inner snap-fit ​​portions 422 being snap-fitted one by one; the plurality of first inner snap-fit ​​portions 322 and the plurality of second outer snap-fit ​​portions 421 being snap-fitted one by one. It is understandable that the first bracket 300 is provided with a first outer snap-fit ​​part 321 and a first inner snap-fit ​​part 322, and the second bracket 400 is provided with a second inner snap-fit ​​part 422 that snaps into the first outer snap-fit ​​part 321 and a second outer snap-fit ​​part 421 that snaps into the first inner snap-fit ​​part 322. This interlocking snap-fit ​​method can improve the snap-fit ​​stability of multiple first snap-fit ​​structures 320 and multiple second snap-fit ​​structures 420, improve the connection strength of the first bracket 300 and the second bracket 400, reduce the probability of deformation of the first bracket 300 and the second bracket 400, and improve the protection capability for multiple individual battery cells 200.

[0042] It should be further explained that the snap-fit ​​structure of the first outer snap-fit ​​part 321 and the second outer snap-fit ​​part 421 is disposed outward from the single cell 200, while the snap-fit ​​structure of the first inner snap-fit ​​part 322 and the second inner snap-fit ​​part 422 is disposed inward towards the single cell 200.

[0043] It should be noted that in this embodiment, there are two of each of the first outer card connector 321, the first inner card connector 322, the second outer card connector 421, and the second inner card connector 422. In other embodiments of this utility model, the number of the first outer card connector 321, the first inner card connector 322, the second outer card connector 421, and the second inner card connector 422 can be selected according to actual needs.

[0044] Further optional, see reference Figures 7-8As shown, the first outer snap-fit ​​portion 321, the first inner snap-fit ​​portion 322, the second outer snap-fit ​​portion 421, and the second inner snap-fit ​​portion 422 are all formed as hooks, and each has a hook portion 101 and a groove portion 102. It is understood that during actual assembly, the hook portion 101 on the first outer snap-fit ​​portion 321 can engage with the groove portion 102 of the second inner snap-fit ​​portion 422, the groove portion 102 on the first outer snap-fit ​​portion 321 can engage with the hook portion 101 of the second inner snap-fit ​​portion 422, the hook portion 101 on the second outer snap-fit ​​portion 421 can engage with the groove portion 102 of the first inner snap-fit ​​portion 322, and the groove portion 102 on the second outer snap-fit ​​portion 421 can engage with the hook portion 101 of the first inner snap-fit ​​portion 322. This hook-type snap-fit ​​structure can further improve the connection strength between the first bracket 300 and the second bracket 400, and reduce the probability of deformation of the first bracket 300 and the second bracket 400.

[0045] Optional, see reference Figures 3-4 As shown, the first outer snap-fit ​​portion 321 protrudes from the outer surface of the first bracket 300, and at least one first support rib 3211 is provided on the first outer snap-fit ​​portion 321, which abuts against the inner sidewall of the energy storage shell 100. It can be understood that by having the first outer snap-fit ​​portion 321 protrude from the outer surface of the first bracket 300, a travel path can be avoided during mold design, allowing for direct insertion from top to bottom. Furthermore, because the first outer snap-fit ​​portion 321 has a first support rib 3211 abutting against the inner sidewall of the energy storage shell 100, multiple individual batteries 200, the first bracket 300, and the second bracket 400 are centrally positioned during battery module handling or transportation, resulting in more balanced force distribution and reducing the likelihood of compression, thus enhancing the protection of the individual batteries 200. In this embodiment, there are two first support ribs 3211; however, in other embodiments of this invention, the number of first support ribs 3211 can be adjusted according to actual needs.

[0046] Optional, see reference Figures 3-4As shown, the second outer snap-fit ​​portion 421 protrudes from the outer surface of the second bracket 400, and at least one second support rib 4211 is provided on the second outer snap-fit ​​portion 421, which abuts against the inner sidewall of the energy storage shell 100. It can be understood that by having the second outer snap-fit ​​portion 421 protrude from the outer surface of the second bracket 400, a travel path can be avoided during mold design, allowing for direct insertion from top to bottom. Furthermore, because the second outer snap-fit ​​portion 421 has a second support rib 4211 abutting against the inner sidewall of the energy storage shell 100, multiple individual batteries 200, the first bracket 300, and the second bracket 400 are centrally positioned during battery module handling or transportation, resulting in more balanced force distribution and reducing the likelihood of compression, thus enhancing the protection of the individual batteries 200. In this embodiment, there are two second support ribs 4211; however, in other embodiments of this invention, the number of second support ribs 4211 can be adjusted according to actual needs.

[0047] refer to Figure 7 and Figure 9 As shown, the snap-fit ​​structure includes a first limiting rib 3221, which is disposed on the first inner snap-fit ​​portion 322 and abuts against at least one end of the second outer snap-fit ​​portion 421 along its width direction. It can be understood that when the first inner snap-fit ​​portion 322 snaps onto the second outer snap-fit ​​portion 421, the first limiting rib 3221 abuts against one side of the second outer snap-fit ​​portion 421 along its width direction. The first limiting rib 3221 restricts the rotation of the second outer snap-fit ​​portion 421 relative to the first inner snap-fit ​​portion 322, thus limiting the relative rotation of the entire first bracket 300 relative to the second bracket 400, thereby ensuring the connection stability of the first bracket 300 and the second bracket 400.

[0048] Of course, in an alternative embodiment of this utility model, the snap-fit ​​structure includes a second limiting rib, which is disposed on the second inner snap-fit ​​portion 422 and abuts against at least one end of the first outer snap-fit ​​portion 321 along its width direction. Since the second limiting rib abuts against at least one end of the first outer snap-fit ​​portion 321 along its width direction, it can restrict the first bracket 300, preventing the first bracket 300 from rotating relative to the second bracket 400, thereby ensuring the connection stability of the first bracket 300 and the second bracket 400.

[0049] refer to Figure 6 , Figure 10 and Figure 11As shown, the second positioning post 410 is provided with a positioning hole 411, and the end of the first positioning post 310 can be inserted into the positioning hole 411. It is understood that in the actual assembly process, it is only necessary to align the first bracket 300 with the second bracket 400 to ensure that the first positioning post 310 can be inserted into the positioning hole 411, which is convenient and has good positioning reliability. Optionally, the inner wall of the positioning hole 411 is provided with a positioning groove 412, and the first positioning post 310 is provided with a positioning insert edge 311 that cooperates with the positioning groove 412. It is understood that when the first positioning post 310 is inserted into the positioning hole 411, the positioning insert edge 311 can be inserted into the positioning groove 412. This improves the connection reliability between the first positioning post 310 and the second positioning post 410, and restricts the rotation of the first positioning post 310 relative to the second positioning post 410, thereby restricting the rotation of the entire first bracket 300 relative to the second bracket 400 and ensuring the connection stability of the first bracket 300 and the second bracket 400. In addition, the cooperation between the positioning insert 311 and the positioning groove 412 can also play a role in preventing mistakes. In the actual assembly process, the first positioning post 310 can be inserted into the positioning hole 411 only when the positioning insert 311 is aligned with the positioning groove 412, which restricts the installation direction of the first bracket 300 and avoids the phenomenon of misaligned installation of the first bracket 300.

[0050] In an alternative embodiment of this invention, the positioning hole 411 is formed as a polygonal insertion hole, and the first positioning post 310 is positioned as a polygonal insertion post that mates with the polygonal insertion hole. This also effectively restricts the installation direction of the first bracket 300 and limits the rotation of the first positioning post 310 relative to the second positioning post 410.

[0051] refer to Figure 2 and Figure 10 As shown, the first support 300 is provided with a plurality of first balancing ribs 330. The plurality of first balancing ribs 330 are arranged at intervals along the outer contour of the first support 300 and are spaced apart from the inner sidewall of the energy storage shell 100. It can be understood that, in actual operation, if the energy storage shell 100 deforms, the presence of the plurality of first balancing ribs 330 can ensure that the plurality of individual batteries 200, the first support 300 and the second support 400 remain in a central position, achieving force balance with the energy storage shell 100 in all directions, and protecting the internal components of the battery module.

[0052] refer to Figure 11As shown, the second support 400 is provided with a plurality of second balancing ribs 430. The plurality of second balancing ribs 430 are arranged at intervals along the outer contour of the second support 400 and are spaced apart from the inner sidewall of the energy storage shell 100. It can be understood that, in actual operation, if the energy storage shell 100 deforms, the presence of the plurality of second balancing ribs 430 can ensure that the plurality of individual batteries 200, the first support 300 and the second support 400 remain in a central position, achieving force balance with the energy storage shell 100 in all directions, and protecting the internal components of the battery module.

[0053] refer to Figures 4-5 As shown, the first bracket 300 has a first arrowhead portion 340 extending towards the second bracket 400, and the second bracket 400 has a second arrowhead portion 440 extending towards the first bracket 300. After the first bracket 300 and the second bracket 400 are assembled, the first arrowhead portion 340 and the second arrowhead portion 440 are positioned facing each other. It is understood that in the actual assembly process, the correct assembly direction for the first bracket 300 and the second bracket 400 is when the first arrowhead portion 340 and the second arrowhead portion 440 are aligned, achieving a visual error-proof effect. In this embodiment of the invention, there are two first arrowhead portions 340 and two arrowhead portions 440. Of course, in other embodiments of the invention, the number of first arrowhead portions 340 and second arrowhead portions 440 can be adjusted according to actual needs.

[0054] The advantages of the battery module in this embodiment are as follows:

[0055] First, the number of fixing screws is greatly reduced. The first bracket 300 and the second bracket 400 are fixed with only one screw, which simplifies the production process, improves assembly efficiency, and reduces manufacturing costs.

[0056] Second, the first outer snap-fit ​​part 321 and the second inner snap-fit ​​part 422 snap-fit ​​together, forming an interlocking structure, which makes the interaction force between the individual battery cells 200 tighter and the product more stable.

[0057] Third: Reduce product size. Compared with the existing screw fixing method, the use of the first snap-fit ​​structure 320 and the second snap-fit ​​structure 420 significantly reduces the size of the first bracket 300 and the second bracket 400.

[0058] Fourth: The entire battery module and the energy storage shell 100 are subjected to balanced forces, and the forces are directly transmitted to the energy storage shell 100;

[0059] Fifth: The first bracket 300 and the second bracket 400 do not rotate after assembly to ensure welding accuracy and product assembly accuracy.

[0060] This utility model also discloses an energy storage power supply, including an energy storage housing 100 and the aforementioned battery module, with the battery module housed within the energy storage housing 100. The assembly process of this energy storage power supply is simple, and the battery module exhibits good stability and relatively balanced stress distribution.
