[0037] With the development of the electric vehicle industry, new energy vehicle technologies, centered on three core technologies—power electrification, lightweight structure, and vehicle intelligence—are now undergoing in-depth development. Existing battery packs generally include battery modules, a BMS (Battery Management System), connectors, etc.

[0038] The Battery Management System (BMS) is primarily used to monitor and regulate the operating status of the modules. The BMS needs to be mounted on a support assembly. Due to variations in the number and arrangement of batteries within the battery pack, the installation space allocated to the BMS also varies. Furthermore, the installation angle of the BMS differs, necessitating different types of support assemblies. This results in low versatility of existing support assemblies and high costs for the battery system.

[0039] To address the aforementioned issues, this application proposes a bracket assembly. By allowing relative rotation between the bracket structure and the support structure, the installation angle of the battery management module can be easily adjusted. This enables the bracket assembly to adapt to various battery management module installation environments, enhancing its versatility and reducing the manufacturing cost of the battery device.

[0040] It is understood that the following embodiments of this application are only used as an example of applying the bracket assembly into the battery device to support the battery management module. However, the technical solutions provided by the embodiments of this application are not limited to the following embodiments. They can also be used to support other functional boards in any three-dimensional space such as energy storage box and control module box, and to protect them.

[0041] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 This is a partial structural schematic diagram of a battery device provided in one embodiment of this application; Figure 2 This is a schematic diagram of the structure of the support assembly 1 provided in one embodiment of this application; Figure 3 This is a schematic diagram of the structure of the support assembly 1 provided in one embodiment of this application; Figure 4 This is a schematic diagram of the structure of the support assembly 1 provided in another embodiment of this application.

[0042] Firstly, such as Figures 1 to 4As shown in the embodiment of this application, a bracket assembly 1 is proposed for connection with a battery management module 4. The bracket assembly 1 includes a support structure 2 and a bracket structure 3. The support structure 2 includes a panel 21 and two side plates 22 connected to each other. The two side plates 22 are respectively disposed on both sides of the panel 21 in a first direction X and extend in a second direction Y. The panel 21 is used to connect with the battery management module 4. The first direction X and the second direction Y intersect. The bracket structure 3 is connected to the side plates 22, and the bracket structure 3 is rotatably arranged relative to the side plates 22 around the first direction X. The support structure 2 is connected to the installation position inside the battery box through the bracket structure 3.

[0043] In the bracket assembly 1 provided in this application embodiment, the bracket assembly 1 includes a support structure 2 and a bracket structure 3 that are interconnected. The support structure 2 includes a panel 21 and two side plates 22 that are interconnected. The battery management module 4 is connected to the panel 21. The two side plates 22 are respectively disposed on both sides of the panel 21 in the first direction X and extend along the second direction Y to facilitate the connection between the support structure 2 and the bracket structure 3. The bracket structure 3 can be connected to the installation position inside the battery box to maintain the stability of the battery management module 4. The bracket structure 3 is rotatable relative to the side plates 22 around the first direction X. By setting the relative rotation of the bracket structure 3 and the support structure 2, the installation angle of the battery management module 4 can be easily adjusted so that the bracket assembly 1 can adapt to a variety of different battery management module 4 installation environments, which helps to enhance the versatility of the bracket assembly 1 and reduce the manufacturing cost of the battery device.

[0044] For example, the bracket assembly 1 provided in this application embodiment can be used to fix the BMS motherboard or BMS slave board, etc. The following description takes the BMS motherboard as an example.

[0045] The support structure 2 includes a panel 21 and two side plates 22 that are connected to each other. For example, the panel 21 is provided with bolt holes, and the two side plates 22 are respectively disposed on both sides of the panel 21 in the first direction X. The BMS main board is fixed to the panel 21 by bolts and is located between the two side plates 22.

[0046] Optionally, the side panel 22 and the panel 21 are integrally formed to enhance the structural strength of the support structure 2. For example, the side panel 22 and the panel 21 are integrally stamped or integrally injection molded.

[0047] Optionally, the first direction X is the length or width direction of the panel 21, and the second direction Y is the thickness direction of the panel 21.

[0048] Optionally, the support assembly 1 includes two support structures 3, which are respectively connected to two side plates 22 to enhance the stability of the support assembly 1.

[0049] The bracket structure 3 and the side plate 22 are rotatably arranged relative to each other around the first direction X, so that the angle of the bracket structure 3 and the side plate 22 is adjustable, so as to facilitate the adjustment of the installation angle of the BMS motherboard and enhance the versatility of the bracket assembly 1.

[0050] For example, for battery devices of various specifications with different installation angles, the bracket structure 3 can be fixed in the installation position first, and then the support structure 2 and the bracket structure 3 can be rotated relative to each other to achieve the expected installation angle of the BMS motherboard.

[0051] Alternatively, for battery devices of different specifications with different installation positions, the BMS main board is first fixed to the panel 21 at a suitable installation angle, and then the support structure 2 and the bracket structure 3 are rotated relative to each other so that the bracket structure 3 can be fixed in different installation positions.

[0052] By adjusting the position of the bracket structure 3, the specific installation angle of the battery management module 4 inside the battery box can be adjusted, which facilitates the planning of the wiring harness structure inside the box, helps to improve the utilization rate of the internal space of the box, and improves the energy density of the battery device.

[0053] The fact that the support structure 3 is rotatable relative to the side plate 22 means that the support structure 3 can be rotated to at least two different expected positions relative to the side plate 22, and that the support structure 3 can be fixedly connected to the side plate 22 in each of the different expected positions.

[0054] For example, the side plate 22 is provided with a threaded rod protruding out, and the support structure 3 is sleeved on the threaded rod so that the support structure 3 can rotate relative to the side plate 22. After the support structure 3 is in the expected position, the support structure 3 and the side plate 22 are fixed by a nut; or the support structure 3 is provided with a threaded rod protruding out, and the side plate 22 is sleeved on the threaded rod so that the support structure 3 can rotate relative to the side plate 22. After the support structure 3 is in the expected position, the support structure 3 and the side plate 22 are fixed by a nut.

[0055] Please see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the support structure 2 of the bracket assembly 1 provided in an embodiment of this application; Figure 6 This is a schematic diagram of the support structure 3 of the support assembly 1 provided in an embodiment of this application.

[0056] In some embodiments, such as Figures 2 to 6As shown, the side plate 22 is provided with a first connecting hole 221. The bracket structure 3 includes a body 31 and a first connecting member 32. The body 31 includes a connecting structure and a second connecting hole arranged at intervals. The connecting structure is used to connect with the installation position. The body 31 is rotatably arranged relative to the side plate 22 about a first direction X. The first connecting member 32 passes through the first connecting hole 221 and the second connecting hole to connect the body 31 and the side plate 22.

[0057] In these embodiments, the bracket structure 3 includes a body 31 and a first connector 32. The first connector 32 can pass through the second connecting hole of the body 31 and the first connecting hole 221 of the side plate 22 to fix the body 31 and the side plate 22. This helps to reduce the processing difficulty of the side plate 22 and the body 31 while enabling the bracket structure 3 to rotate relative to the side plate 22.

[0058] Optionally, the connection structure can be a through hole or a threaded hole, with studs or rivets passing through the connection structure and the mounting position of the battery box to achieve a threaded connection or riveting; or the body 31 can be welded to the connection structure and the mounting position. The mounting position can be located at the beam or wall panel of the battery box, etc.

[0059] Optionally, the first connector 32 is a stud and a nut. The stud passes through the first connecting hole 221 and the second connecting hole and the nut to fix the side plate 22 and the body 31. The body 31 is rotatable relative to the side plate 22 about the first direction X.

[0060] In some embodiments, such as Figures 2 to 6 As shown, the side plate 22 also includes a first limiting part 222, which is spaced apart from the first connecting hole 221. The body 31 also includes a second limiting part 311, which is spaced apart from the second connecting hole. One of the first limiting part 222 and the second limiting part 311 is a through hole, and the other of the first limiting part 222 and the second limiting part 311 is a boss, with at least a portion of the boss passing through the through hole. Alternatively, both the first limiting part 222 and the second limiting part 311 are through holes. The bracket structure 3 also includes a second connecting member 34, which passes through the first limiting part 222 and the second limiting part 311 to connect the body 31 and the side plate 22.

[0061] In these embodiments, the first limiting part 222 and the second limiting part 311 cooperate to fix the bracket structure 3 and the support structure 2 in the expected position, thereby reducing the risk of misalignment of the bracket structure 3 and the support structure 2 and improving the reliability of the bracket assembly 1.

[0062] The support structure 3 can rotate relative to the support structure 2 between at least two expected positions. When the support structure 3 is in an expected position, the support structure 3 may be misaligned under the action of external force. In order to improve the above problem, a first limiting part 222 and a second limiting part 311 that cooperate with each other are provided on the body 31 and the side plate 22, respectively, so that when the support structure 3 is in the expected position, the first limiting part 222 and the second limiting part 311 that cooperate with each other prevent the relative rotation of the support structure 3 and the support structure 2 under the action of external force.

[0063] The first limiting part 222 and the second limiting part 311 are engaged by a boss and a through hole. At least part of the boss extends into the through hole to avoid relative rotation between the bracket structure 3 and the support structure 2. The way in which the boss extends into the through hole helps to reduce the difficulty of engaging the support structure 2 and the bracket structure 3.

[0064] For example, the first limiting part 222 is a boss and the second limiting part 311 is a through hole; or the first limiting part 222 is a through hole and the second limiting part 311 is a boss.

[0065] The first limiting part 222 and the first connecting hole 221 are spaced apart. When the first limiting part 222 is a through hole, the spaced arrangement of the through hole and the first connecting hole 221 helps to balance the force on the side plate 22 and reduce the risk of tearing of the side plate 22. When the first limiting part 222 is a boss, the spaced arrangement of the boss and the first connecting hole 221 helps to reduce the processing difficulty of the side plate 22.

[0066] Optionally, the shape and size of the boss and the through hole can be designed by the user. For example, the through hole is a round hole and the boss is cylindrical; or the through hole is a rectangular hole and the boss is cubic.

[0067] Both the first limiting part 222 and the second limiting part 311 are through holes. The second connecting member 34 passes through the two through holes to connect the side plate 22 and the body 31, so as to avoid relative rotation between the bracket structure 3 and the support structure 2. The way in which the boss extends into the through hole helps to reduce the processing difficulty of the support structure 2 and the bracket structure 3, and helps to improve the connection reliability of the bracket structure 3 and the support structure 2.

[0068] For example, the second connector 34 is a bolt or pin, etc.

[0069] For example, when the support structure 3 is in the expected position, the first limiting part 222 and the second limiting part 311 overlap, and the second connector 34 is inserted to prevent the support structure 3 and the support structure 2 from being misaligned.

[0070] In some embodiments, such as Figures 2 to 6As shown, the side plate 22 also includes a plurality of first limiting parts 222, which are spaced apart around the first connecting hole 221, and / or the body 31 also includes a plurality of second limiting parts 311, which are spaced apart around the second connecting hole.

[0071] In these embodiments, multiple first limiting parts 222 are spaced apart around the first connecting hole 221, and / or multiple second limiting parts 311 are spaced apart around the second connecting hole. That is, the bracket structure 3 can be fixed relative to the support structure 2 at multiple expected positions, so that the bracket assembly 1 can adapt to more application scenarios and improve the versatility of the bracket assembly 1.

[0072] Optionally, the specific number of the first limiting part 222 can be designed by the user. For example, the number of the first limiting part 222 can be 2, 3, 4, 5, etc. The same applies to the second limiting part 311.

[0073] Optionally, the number of first limiting portions 222 and second limiting portions 311 may be the same or different. For example, the side plate 22 includes a plurality of first limiting portions 222 and the body 31 includes a second limiting portion 311; or the side plate 22 includes a first limiting portion 222 and the body 31 includes a plurality of second limiting portions 311.

[0074] Optionally, multiple first limiting portions 222 are evenly distributed at equal intervals to distribute the force on the side plate 22 and reduce the risk of tearing of the side plate 22. The same applies to the second limiting portion 311.

[0075] In some embodiments, such as Figures 2 to 6 As shown, the angle between the two lines connecting the center of the adjacent first limiting part 222 to the center of the first connecting hole 221 is 90°.

[0076] In these embodiments, the included angle between the two lines connecting the center of the adjacent first limiting part 222 to the center of the first connecting hole 221 is 90°. This allows the battery management module 4 to be fixed vertically or horizontally while reducing the number of first limiting parts 222 and second limiting parts 311 and reducing the processing difficulty of the bracket assembly 1.

[0077] In related technologies, the battery management module 4 is often installed in a vertical or horizontal position within the battery box. Therefore, the bracket assembly 1 in this embodiment should be adaptable to the installation conditions of the battery management module 4 in both of these states. For example, Figure 3 This shows the state of bracket assembly 1 when it is in a vertical position. Figure 4 This shows the state of support assembly 1 when it is lying horizontally.

[0078] For example, the bracket assembly 1 includes a first position and a second position spaced apart. When the bracket structure 3 is in the first position, the battery management module 4 can be fixed to the installation position in a horizontal state through the bracket assembly 1. When the bracket structure 3 rotates 90° relative to the support structure 2 from the first position to the second position, the battery management module 4 can be fixed to the installation position in a vertical state through the bracket assembly 1.

[0079] The angle between the two lines connecting the center of the adjacent first limiting part 222 to the center of the first connecting hole 221 is 90°. That is, the angle between the two lines connecting the center of the two adjacent first limiting parts 222 to the center of the first connecting hole 221 is 90°.

[0080] For example, the side plate 22 is provided with two first limiting parts 222, or the side plate 22 is provided with four first limiting parts 222, and the four first limiting parts 222 are evenly spaced. The second limiting part 311 is similar.

[0081] In some embodiments, such as Figures 2 to 6 As shown, the body 31 includes a first wall portion 312 and a second wall portion 313. The first wall portion 312 is attached to the side plate 22. A second connecting hole is provided in the first wall portion 312. The second wall portion 313 is connected to the edge of the first wall portion 312 and extends in the first direction X. A connecting structure is provided in the second wall portion 313.

[0082] In these embodiments, the second connecting hole and the connecting structure are respectively provided on the first wall portion 312 and the second wall portion 313, so as to facilitate the connection between the body 31 and the installation position and the side plate 22, and reduce the installation difficulty of the bracket mechanism and the support structure 2.

[0083] Optionally, in the extending direction of the body 31, the connecting structure and the second connecting hole are respectively located at both ends of the body 31 to reduce the risk of interference between the connecting structure and the first connecting member 32 when they are connected at the mounting position.

[0084] Optionally, the first wall portion 312 and the second wall portion 313 are integrally formed, and the first wall portion 312 and the second wall portion 313 are formed by bending the same substrate.

[0085] For example, the first wall portion 312 is attached to the side plate 22, and a second connecting hole is provided in the first wall portion 312 to facilitate the fixing of the bracket assembly 1 and the side plate 22. The second wall portion 313 is attached to the wall panel or beam inside the battery box to connect the bracket assembly 1 to the mounting position.

[0086] Please see Figure 7 , Figure 7 This is a schematic diagram of the support structure 3 of the support assembly 1 provided in another embodiment of this application.

[0087] In some embodiments, such as Figure 7 As shown, the support structure 3 also includes a support rib 33, one end of which is connected to the side of the first wall portion 312 away from the side plate 22, and the other end is connected to the second wall portion 313.

[0088] In these embodiments, the structural strength of the support structure 3 is enhanced and the stability of the support assembly 1 is improved by providing a support rib 33 between the first wall portion 312 and the second wall portion 313.

[0089] Optionally, the support rib 33 is inclinedly disposed between the first wall portion 312 and the second wall portion 313, and welded to the first wall portion 312 and the second wall portion 313.

[0090] Optionally, the number of support ribs 33 may be one or more, and the multiple support ribs 33 may be spaced apart.

[0091] Please see Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the structure of the support assembly 1 provided in another embodiment of this application; Figure 9 This is a schematic diagram of the structure of the support assembly 1 provided in another embodiment of this application.

[0092] In some embodiments, such as Figure 8 and Figure 9 As shown, panel 21 includes a first sub-panel 211 and a second sub-panel 212 that are connected to each other, and two side panels 22 are respectively connected to the first sub-panel 211 and the second sub-panel 212. The first sub-panel 211 and the second sub-panel 212 are relatively movable in a first direction X.

[0093] In these embodiments, panel 21 includes a first sub-panel 211 and a second sub-panel 212 that are interconnected. The first sub-panel 211 and the second sub-panel 212 are relatively movable in a first direction X so that the bracket assembly 1 can be adapted to battery management modules 4 of different sizes to enhance the versatility of the bracket assembly 1.

[0094] The battery management module 4 in different battery devices has different dimensions in the first direction X. In this embodiment, the first sub-panel 211 and the second sub-panel 212 are relatively movable in the first direction X so that the panel 21 can be connected to the battery management module 4 with different dimensions in the first direction X, so that the bracket assembly 1 can adapt to a variety of different installation environments and improve the versatility of the bracket assembly 1.

[0095] Two side panels 22 are respectively disposed on the first sub-panel 211 and the second sub-panel 212, and both the first sub-panel 211 and the second sub-panel 212 are connected to the battery management module 4.

[0096] For example, the first sub-panel 211 and the second sub-panel 212 are connected by a telescopic rod or linkage assembly, so that the first sub-panel 211 and the second sub-panel 212 are relatively movable in a first direction X.

[0097] In some embodiments, such as Figure 8 As shown, the first sub-panel 211 includes a limiting hole 2111, and a plurality of limiting holes 2111 are spaced apart in the first direction X. The second sub-panel 212 includes a limiting protrusion 2121, which is accommodated in the limiting hole 2111.

[0098] In these embodiments, by using the limiting hole 2111 and multiple limiting holes 2111 together, the processing difficulty of panel 21 is reduced while realizing the relative movement of the first sub-panel 211 and the second sub-panel 212.

[0099] Optionally, multiple limiting holes 2111 are evenly spaced to facilitate adjustment of the size of the panel 21 in the first direction X.

[0100] Optionally, the number of limiting holes 2111 can be determined by the user. For example, the number of limiting holes 2111 can be 2, 3, 5, etc.

[0101] Optionally, the first sub-panel 211 includes at least two rows of spaced-apart limiting holes 2111, and the second sub-panel 212 is provided with at least two corresponding limiting protrusions 2121 to improve the stability of the first sub-panel 211 and the second sub-panel 212 during movement. Each row of limiting holes 2111 includes a plurality of limiting holes 2111 spaced-apart along the first direction X.

[0102] In some embodiments, such as Figure 9 As shown, the first sub-panel 211 includes a first limiting groove 2112 extending in the first direction X, and the second sub-panel 212 includes a second limiting groove 2122 extending in the first direction X. The first limiting groove 2112 and part of the second limiting groove 2122 coincide in the thickness direction of the panel 21. The support structure 2 also includes a third connector 23, which passes through the first limiting groove 2112 and the second limiting groove 2122 to connect the first sub-panel 211 and the second sub-panel 212.

[0103] In these embodiments, the first sub-panel 211 includes a first limiting groove 2112 extending in the first direction X, the second sub-panel 212 includes a second limiting groove 2122 extending in the first direction X, and the third connector 23 passes through the first limiting groove 2112 and the second limiting groove 2122 to connect the first sub-panel 211 and the second sub-panel 212. This makes it easier to adjust the size of the panel 21 in the first direction X, so that the bracket assembly 1 can adapt to more battery management modules 4 of different sizes and improve the versatility of the bracket assembly 1.

[0104] For example, the third connector 23 is a bolt, which passes through the first limiting groove 2112 and the second limiting groove 2122 to fix the first sub-panel 211 and the second sub-panel 212.

[0105] Optionally, the first limiting groove 2112 and the second limiting groove 2122 may have the same or different dimensions in the first direction X.

[0106] Optionally, the first sub-panel 211 includes at least two rows of first limiting grooves 2112 spaced apart, and the second sub-panel 212 includes at least two rows of second limiting grooves 2122 spaced apart, to improve the stability of the first sub-panel 211 and the second sub-panel 212 during movement.

[0107] Secondly, this application provides a battery device including a housing, a battery management module, and a bracket assembly as described in the first aspect embodiment. The battery management module is connected to a panel, and the bracket assembly is connected to the housing.

[0108] The battery device in this application embodiment includes the bracket assembly in any of the first aspects described above. Therefore, the beneficial effects of the battery device in this application embodiment including the bracket assembly in the first aspect embodiment will not be repeated here.

[0109] Thirdly, embodiments of this application provide a vehicle that includes the battery device described in the second aspect of the above-described embodiment.

[0110] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict.
