[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0041] Firstly, such as Figure 1As shown, an embodiment of this application provides a mounting bracket 100 for mounting a battery management element 210. The mounting bracket 100 includes a substrate 10 and a mounting bracket 20. A first fixing member 11 is provided on the substrate 10 for fixing the battery management element 210. The mounting bracket 20 is connected to the substrate 10, and the mounting bracket 20 and the substrate 10 are stacked along a first direction Z, forming a mounting cavity 21 between the mounting bracket 20 and the substrate 10. A first mounting hole 41 is provided on the mounting bracket 20, and the first mounting hole 41 and the first fixing member 11 are arranged opposite to each other along the first direction. The battery management element 210 can be mounted through the first fixing member 11 on the substrate 10. The mounting cavity 21 formed between the mounting bracket 20 and the substrate 10 provides protection for the battery management element 210, and the side of the mounting bracket 20 facing away from the substrate 10 can also be used to mount the battery management element 210, achieving stacked mounting and improving space utilization. The mounting bracket 20 is provided with a first mounting hole 41 that is disposed opposite to the first fixing member 11 along the first direction. The first mounting hole 41 allows for convenient operation of the first fixing member 11, thereby reducing the difficulty of assembling the battery management element 210 onto the substrate 10 and improving assembly efficiency.

[0042] In some embodiments, the fixing bracket 100 further includes a partition 30, at least one partition 30 being disposed within the mounting cavity 21 to divide the mounting cavity 21 into a plurality of mounting sub-cavities stacked along a first direction. The partition 30 is provided with the first mounting hole 41, and the first mounting hole 41 and the first fixing member 11 are disposed opposite to each other along the first direction.

[0043] At least one partition 30 can divide the mounting cavity 21 into multiple mounting sub-cavities stacked along the first direction. Each mounting sub-cavity can be used to install one battery management element 210. The side of the mounting bracket 20 facing away from the substrate 10 can also be used to install the battery management element 210, thereby achieving the purpose of installing multiple battery management elements 210 simultaneously on one fixed bracket 100, making reasonable use of the longitudinal space within the battery pack and improving space utilization. The partition 30 is also provided with a first mounting hole 41 that is opposite to the first fixing member 11 in the first direction, thereby facilitating the operation of the first fixing member 11, reducing assembly difficulty, and improving assembly efficiency.

[0044] like Figure 2As shown, a first sub-mounting cavity 211 is formed between the substrate 10 and the separator 30. The battery management element 210 can be installed in the first sub-mounting cavity 211 via the first fixing member 11 provided on the substrate 10. Since the first mounting hole 41 and the first fixing member 11 are arranged opposite each other along the first direction Z, the first fixing member 11 can be fastened and disassembled along the first direction Z through the first mounting hole 41 during the installation process, thereby achieving the purpose of assembling the battery management element 210 onto the substrate 10. During installation, the battery management element 210 can be inserted into the first sub-mounting cavity 211 along the third direction Y.

[0045] For example, such as Figure 2 As shown, the first fixing member 11 can be a plurality of press-fit studs disposed on the substrate 10, and a plurality of nuts corresponding to the plurality of press-fit studs. When the battery management element 210 is assembled onto the first fixing member 11, the nuts and press-fit studs can be installed and removed through the first mounting hole 41.

[0046] In some embodiments, such as Figure 3 As shown, a second fixing member 33 is provided on the partition 30, which is used to fix the battery management element 210. A second mounting hole 42 is provided on the mounting bracket 20, and the second mounting hole 42 and the second fixing member 33 are arranged opposite to each other along the first direction Z. The second fixing member 33 and the first fixing member 11 are staggered in the second direction, wherein the second direction and the first direction intersect each other.

[0047] The battery management element 210 can be fixed to the substrate 10 by the second fastener 33 on the partition 30, and the second mounting hole 42 provided on the mounting bracket 20 can improve the convenience of assembling the second fastener 33 with the battery management element 210. Figure 3 As shown, a second mounting cavity is formed between the separator 30 and the mounting bracket 20. The battery management element 210 can be installed in the second mounting cavity through the second fixing member 33 provided on the separator 30. Since the second mounting hole 42 and the second fixing member 33 are arranged opposite to each other along the first direction Z, the second fixing member 33 can be fastened and disassembled through the second mounting hole 42 during the installation process, so as to achieve the purpose of assembling the battery management element 210 onto the separator 30.

[0048] By staggering the first fixing member 11 and the second fixing member 33 in the second direction X, the battery management elements 210 mounted on the substrate 10 and the separator 30 can also be staggered. On the one hand, this reduces interference between battery management elements 210 on different layers during assembly; on the other hand, it also reduces electromagnetic interference between adjacent battery management elements 210.

[0049] For example, such as Figure 3 As shown, the second fixing member 33 can be a plurality of press-fit studs provided on the partition plate 30, and a plurality of nuts corresponding to the press-fit studs. When the battery management element 210 is assembled onto the second fixing member 33, the nuts and press-fit studs can be installed and removed through the second mounting hole 42.

[0050] In some embodiments, such as Figure 4 As shown, a third fixing member 22 is provided on the side of the mounting bracket 20 away from the substrate 10. The third fixing member 22 is used to fix the battery management element 210.

[0051] By providing a third fixing member 22 on the side of the mounting bracket 20 away from the substrate 10, the battery management element 210 can be mounted on the side of the mounting bracket 20 away from the substrate 10, thereby improving the space utilization and achieving the purpose of stacking multiple battery management elements 210.

[0052] For example, such as Figure 4 As shown, the third fastener 22 can also be a plurality of press-fit studs provided on the partition plate 30, and a plurality of nuts corresponding to the press-fit studs. Since the space on the side of the mounting bracket 20 away from the base plate 10 is not interfered with by other components, no corresponding mounting holes are required.

[0053] It is understandable that the multiple press-fit studs included in the first fixing member 11, the second fixing member 33 and the third fixing member 22 mentioned above can be directly integrated into the base plate 10, the partition plate 30 or the mounting bracket 20 to ensure structural stability.

[0054] In some embodiments, such as Figures 2-4 As shown, the first fixing member 11, the second fixing member 33, and the third fixing member 22 are staggered in the second direction X. The second direction X intersects the first direction Z.

[0055] The first fixing member 11, the second fixing member 33, and the third fixing member 22 are used to fix battery management elements 210 of different layers, respectively. By staggering the first fixing member 11, the second fixing member 33, and the third fixing member 22 in the second direction X, the battery management elements 210 mounted on the substrate 10, the separator 30, and the mounting bracket 20 can also be staggered. On the one hand, this reduces interference between battery management elements 210 of different layers during assembly; on the other hand, it also reduces electromagnetic interference between adjacent battery management elements 210.

[0056] It is understandable that, since the first mounting hole 41 is positioned opposite to the first fixing member 11 along the first direction Z, and the second mounting hole 42 is positioned opposite to the second fixing member 33 along the first direction Z, when the first fixing member 11 and the second fixing member 33 are staggered in the second direction X, the first mounting hole 41 and the second mounting hole 42 are also staggered in the second direction X. By staggering the first mounting hole 41 and the second mounting hole 42, interference during the assembly of battery management components 210 of different layers can be reduced.

[0057] In some embodiments, such as Figures 1-4 As shown, the partition 30 includes at least a first sub-partition 31 and a second sub-partition 32 spaced apart along the first direction Z. The second fixing member 33 includes a first sub-fixing member 311 and a second sub-fixing member 321, with the first sub-fixing member 311 disposed on the first sub-partition 31 and the second sub-fixing member 321 disposed on the second sub-partition 32. The first sub-fixing member 311 and the second fixing member 321 are staggered along the second direction X.

[0058] The first sub-partition 31 and the second sub-partition 32 can increase the number of mounting sub-cavities and the number of battery management elements 210 that can be assembled. By staggering the first sub-fixing member 311 and the second sub-fixing member 321 in the second direction X, mutual interference between the battery management elements 210 mounted on the first sub-partition 31 and the battery management elements 210 mounted on the second sub-partition 32 can be reduced, and electromagnetic interference between adjacent battery management elements 210 can also be reduced.

[0059] It is understood that those skilled in the art can set the number of sub-separators in the separator 30 as needed. For example, the number of sub-separators in the separator 30 can be 3, 4 or 5, etc. By increasing the number of sub-separators, the number of installation sub-cavities can be increased accordingly, and the number of battery management elements 210 can be increased.

[0060] like Figure 1 As shown, a first sub-mounting cavity 211 is formed between the first sub-partition 31 and the substrate 10, a second sub-mounting cavity 212 is formed between the first sub-partition 31 and the second sub-partition 32, and a third sub-mounting cavity 213 is formed between the second sub-partition 32 and the mounting bracket 20, which can be used to mount the battery management element 210 respectively.

[0061] It is understandable that when the second fixing member 33 includes the first sub-fixing member 311 and the second sub-fixing member 321, the second mounting hole 42 also correspondingly includes the first sub-mounting hole 421 and the second sub-mounting hole 422 to facilitate the assembly of the first sub-fixing member 311 and the second sub-fixing member 321. Furthermore, the number of separators 30 can be set according to actual needs; for example, a third sub-separator 30 may also be included. By increasing the number of separators 30, the number of battery management elements 210 that can be assembled can be increased accordingly. However, this also places higher demands on the height space in the first direction Z. Those skilled in the art can set this according to actual needs.

[0062] In some embodiments, such as Figure 5 As shown, the mounting bracket 20 has a first baffle 23 on one side in the third direction Y. The first baffle 23 is used to block at least part of the opening of the mounting cavity 21 on the third direction Y side. The third direction Y intersects with the first direction Z and the second direction X in pairs.

[0063] By shielding at least part of the opening of the mounting cavity 21 on the Y-axis side, the first baffle 23 provides protection for the assembled battery management element 210. Simultaneously, the first baffle 23 also enhances the overall structural strength of the mounting bracket 100.

[0064] For example, such as Figure 5 As shown, the mounting bracket 20 is bent along the first direction Z to form a first baffle 23. The first baffle 23 can partially block the opening of the third mounting sub-cavity on the third direction Y side, thus providing protection for the battery management element 210 assembled in the third mounting sub-cavity. When assembling the battery management element 210, it can be inserted into the third mounting sub-cavity through the opening on the third direction Y opposite to the first baffle 23. Because the mounting bracket 20 is bent along the first direction Z to form the first baffle 23, the structural strength of the mounting bracket 20 itself is also improved.

[0065] In some embodiments, such as Figure 5 As shown, a second baffle 34 is provided on the side of the partition 30 in the third direction Y, and the second baffle 34 is used to block at least part of the opening of the mounting cavity 21 on the third direction Y side.

[0066] Similarly, by blocking at least part of the opening of the mounting cavity 21 on the Y-direction side, the assembled battery management element 210 can be protected. At the same time, the second baffle 34 can also improve the overall structural strength of the mounting bracket 100.

[0067] For example, such as Figure 5As shown, the first sub-partition 31 is bent along the first direction Z to form the first sub-baffle 312, and the second sub-partition 32 is bent along the first direction Z to form the second sub-baffle 322. The second baffle 34 includes the first sub-baffle 312 and the second sub-baffle 322. The second baffle 34 can partially block the openings of the second sub-mounting cavity 212 and the first sub-mounting cavity 211 on the third direction Y, and can provide protection for the battery management element 210 assembled in the second sub-mounting cavity 212 and the first sub-mounting cavity 211. When the battery management element 210 is assembled, it can be inserted into the second sub-mounting cavity 212 and the first sub-mounting cavity 211 through the openings on the third direction Y that are opposite to the second baffle 34. Since the first sub-partition 31 is bent along the first direction Z to form the first sub-baffle 312, and the second sub-partition 32 is bent along the first direction Z to form the second sub-baffle 322, the structural strength of the first sub-partition 31 and the second sub-partition 32 themselves can also be improved.

[0068] In some embodiments, such as Figure 5 As shown, a third baffle 12 is provided on one side of the substrate 10 in the third direction Y, and the third baffle 12 is used to block at least part of the opening of the mounting cavity 21 on the third direction Y side.

[0069] Similarly, by blocking at least part of the opening of the mounting cavity 21 on the Y-direction side, the assembled battery management element 210 can be protected. At the same time, the third baffle 12 can also improve the overall structural strength of the mounting bracket 100.

[0070] For example, such as Figure 5 As shown, the substrate 10 is bent along the first direction Z to form a third baffle 12. The third baffle 12 can partially block the opening of the first mounting cavity on the third direction Y side, thus providing protection for the battery management element 210 assembled in the first mounting cavity. When assembling the battery management element 210, it can be inserted into the first mounting cavity through the opening on the third direction Y that is opposite to the third baffle 12. Since the substrate 10 is bent along the first direction Z to form the third baffle 12, the structural strength of the substrate 10 itself can also be improved.

[0071] In some embodiments, such as Figure 1 As shown, a support structure 13 is provided on the side of the substrate 10 away from the mounting bracket 20, and the support structure 13 is used to support the fixed bracket 100.

[0072] The support structure 13 supports the mounting bracket 100, improving its stability when installed in structures such as battery pack housings. Furthermore, by supporting the substrate 10, separator 30, and mounting bracket 20, the support structure 13 also creates another mounting space on the side of the substrate 10 facing away from the mounting bracket 20, improving space utilization. For example, since the battery management element 210 is typically a low-voltage element, the mounting space created by the support structure 13 can be used to arrange high-voltage elements, enabling separate installation of low-voltage and high-voltage elements, thus improving space utilization and safety performance.

[0073] For example, one side of the substrate 10 is bent away from the mounting bracket 20 to form a support structure 13, which simplifies the structure and ensures the support stability of the support structure 13.

[0074] In some embodiments, such as Figure 5 and Figure 6 As shown, the fixed bracket 100 is also provided with a connecting structure 14, which is used to fix the mounting bracket 20. Through the connecting structure 14, the fixed bracket 100 can be easily connected and fixed to other components, thereby realizing the installation and fixation of the fixed bracket 100.

[0075] For example, such as Figures 5-6 As shown, the fixed bracket 100 is provided with a snap-fit ​​structure to snap the fixed bracket 100 onto other structures, thereby achieving the connection and fixation of the fixed bracket 100.

[0076] It is understood that the connection structure 14 can also be a bolt connection structure, a pin connection structure, or other structures, and those skilled in the art can set it as needed.

[0077] Secondly, such as Figure 6 As shown, an embodiment of this application provides a battery management component 200, including a battery management element 210 and a mounting bracket 20 as described above. The battery management element 210 is mounted on the mounting bracket 20.

[0078] The battery management component 200 provided in this application embodiment has all the beneficial effects of the fixing bracket 100 as described above, and will not be repeated here.

[0079] In some embodiments, such as Figure 6 As shown, multiple battery management elements 210 are stacked along the first direction Z, and the multiple battery management elements 210 are staggered along the second direction X. The first direction Z and the second direction X intersect each other.

[0080] By stacking multiple battery management elements 210 along the first direction Z, the longitudinal space can be utilized, reducing the space occupied by the arrangement of multiple battery management elements 210 and improving space utilization. Furthermore, by staggering the arrangement of multiple battery management elements 210 along the second direction X, mutual interference between different battery management elements 210 during installation can be reduced, as can electromagnetic interference generated during the operation of the battery management elements 210.

[0081] Thirdly, embodiments of this application also provide a battery pack, including the battery management component 200 as described above.

[0082] The battery pack provided in this application embodiment has all the beneficial effects of the fixing bracket 100 as described above, and will not be repeated here.

[0083] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
