[0021] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0022] The following is for reference. Figures 1-5 The battery management system bracket assembly 1 according to an embodiment of the present utility model is described.

[0023] like Figures 1-5 As shown, the battery management system bracket assembly 1 according to an embodiment of the present invention includes: a base plate 10, a main board bracket 20, and a slave board bracket 30. The base plate 10 provides a stable mounting surface and can be used to mount and fix components such as the main board bracket 20 and the slave board bracket 30. The main board bracket 20 can be used to fix and support the battery management system main board 200, and the slave board bracket 30 can be used to fix and support the battery management system slave board 300.

[0024] like Figure 1 and Figure 2As shown, the mainboard bracket 20 is disposed on one side of the base plate 10. The mainboard bracket 20 is used to fix the battery management system mainboard 200. The slave board bracket 30 is disposed on one side of the base plate 10. The two sides of the slave board bracket 30 are used to fix a battery management system slave board 300. The main board bracket 20 and the slave board bracket 30 are located on the same side of the base plate 10. The base plate 10 can then fix and support the main board bracket 20 and the slave board bracket 30, facilitating their installation. The main board bracket 20 is used to fix the battery management system main board 200, ensuring that the main board 200 has a fixed and precise position within the battery. This prevents the main board 200 from shifting or loosening due to vibration, impact, etc. The slave board bracket 30 has two sides used to fix a battery management system slave board 300, ensuring that the slave board 300 has a fixed and precise position within the battery. This also prevents the slave board 300 from shifting or loosening due to vibration, impact, etc. Furthermore, this design simplifies the structure, reduces the number of parts, and significantly saves internal battery space, reducing assembly complexity.

[0025] Therefore, by setting up the motherboard bracket 20 and the slave board bracket 30, the battery management system motherboard 200 and the battery management system slave board 300 can be centrally arranged and fixed. The arrangement scheme is simple, the fixing reliability is high, and it is convenient for wire harness insertion. At the same time, it can save the internal space of the battery. In addition, it can be assembled as a whole during the battery assembly process, thereby improving the assembly efficiency.

[0026] Specifically, such as Figures 1-5 As shown, in the first direction, the motherboard bracket 20 and the slave board bracket 30 are arranged opposite to each other. In the first direction, the motherboard bracket 20 and the slave board bracket 30 are spaced apart. At this time, a battery management system slave board 300 can be fixed in the space between the slave board bracket 30 and the motherboard bracket 20. Thus, a battery management system slave board 300 can be fixed on each side of the slave board bracket 30. This simplifies the structure, reduces the number of parts, and thus greatly saves the internal space of the battery and reduces the assembly complexity.

[0027] Among them, such as Figures 1-5 As shown, a first connecting post 201 is provided on the side of the main board bracket 20 away from the secondary board bracket 30, and a second connecting post 301 and a third connecting post 302 are respectively provided on both sides of the secondary board bracket 30 in the first direction.

The battery management system main board 200 is fixed to the first connecting post 201, thus fixing the battery management system main board 200 to the main board bracket 20, ensuring that the battery management system main board 200 has a fixed and precise position within the battery, and preventing the battery management system main board 200 from shifting or loosening due to vibration, impact, etc. The two battery management system slave boards 300 are respectively fixed to the second connecting post 301 and the third connecting post 302, thus fixing the two battery management system slave boards 300 to both sides of the slave board bracket 30, ensuring that the battery management system slave boards 300 have a fixed and precise position within the battery, and preventing the battery management system slave boards 300 from shifting or loosening due to vibration, impact, etc. The battery management system motherboard 200 can be fixed to the motherboard bracket 20 by welding studs, and the battery management system slave board 300 can be fixed to the slave board bracket 30 by welding studs.

[0029] In addition, such as Figures 1-5 As shown, the battery management system bracket assembly 1 also includes a wiring harness fixing bracket 40. The wiring harness fixing bracket 40 is disposed on one side of the base plate 10, and is also disposed on one side of the main board bracket 20 and the slave board bracket 30 in a second direction, with the first direction perpendicular to the second direction. The wiring harness fixing bracket 40 can be used to fix the wiring harness. The wiring harness fixing bracket 40, the main board bracket 20, and the slave board bracket 30 are disposed on the same side of the base plate 10. In the second direction, the wiring harness fixing bracket 40 is disposed on the same side of the main board bracket 20 and the slave board bracket 30. At this time, the wiring harness is concentrated on one side, which can avoid crossing and tangling, prevent interference between wiring harnesses, and facilitate wiring harness insertion, thereby improving assembly efficiency. The first direction is perpendicular to the second direction.

[0030] Of course, such as Figures 3-5As shown, the motherboard bracket 20 includes: a first main body 202 and a first flange 203. The first flange 203 is connected to one end of the first main body 202 in a third direction. The first main body 202 is connected to the wire harness fixing bracket 40, and the first flange 203 is connected to the base plate 10. The first direction, the second direction and the third direction are arranged perpendicularly to each other. The first main body 202 and the first flange 203 are components of the motherboard bracket 20. The first main body 202 is the main body of the motherboard bracket 20 and is used to fix and support the battery management system motherboard 200. The first flange 203 enables the main bracket to connect with other components, ensuring installation accuracy. The first flange 203 is connected to one end of the first main body 202 in a third direction, forming a whole with the first main body 202, facilitating the installation and setting of the main bracket. The first main body 202 is connected to the wire harness fixing bracket 40, enabling the connection between the motherboard bracket 20 and the wire harness fixing bracket 40, facilitating wire harness insertion and ensuring reliable electrical connection. The first flange 203 is connected to the base plate 10, allowing the motherboard bracket 20 to be positioned on one side of the base plate 10, facilitating the installation and setting of the motherboard bracket 20. The first direction, second direction, and third direction are arranged perpendicularly to each other.

[0031] Furthermore, such as Figures 3-5 As shown, the first main body 202 has a first mounting hole 204 near the end of the wire harness fixing bracket 40, and the first flange 203 has a second mounting hole 205. Fasteners are connected to the wire harness fixing bracket 40 through the first mounting hole 204 and to the base plate 10 through the second mounting hole 205. Both the first mounting hole 204 and the second mounting hole 205 serve a mounting function. The connection between the first main body 202 and the wire harness fixing bracket 40 is achieved through the fasteners and the first mounting hole 204, facilitating wire harness insertion and ensuring reliable electrical connections. The connection between the first flange 203 and the base plate 10 is achieved through the fasteners and the second mounting hole 205, allowing the motherboard bracket 20 to be positioned on one side of the base plate 10, facilitating its installation and setup. The fasteners can be bolts.

[0032] In addition, such as Figures 3-5As shown, the plate support 30 includes: a second main body 303, a second flange 304 and a third flange 305. The second flange 304 and the third flange 305 are respectively connected to the two ends of the second main body 303 in a second direction. The second flange 304 is connected to the wire harness fixing bracket 40 and the third flange 305 is connected to the base plate 10. The second main body 303, the second flange 304, and the third flange 305 are components of the slave plate bracket 30. The second main body 303 is the main body of the slave plate bracket 30 and is used to fix and support the battery management system slave plate 300. The second flange 304 and the third flange 305 enable the slave plate bracket to connect with other components, ensuring installation accuracy. In the second direction, the second flange 304 and the third flange 305 are respectively connected to both ends of the second main body 303. The second flange 304 is connected to the wire harness fixing bracket 40, which enables the slave plate bracket 30 to connect with the wire harness fixing bracket 40, facilitating wire harness insertion and ensuring reliable electrical connection. The third flange 305 is connected to the base plate 10, allowing the slave plate bracket 30 to be positioned on one side of the base plate 10, facilitating the installation and setting of the slave plate bracket 30. It should be noted that the wire harness fixing bracket 40, the slave plate bracket 30, and the base plate 10 can be welded together to form a single unit.

[0033] It should be noted that, as Figures 3-5 As shown, the first main body 202 is provided with a first through hole 206, and the second main body 303 is provided with a second through hole 306. Both the first through hole 206 and the second through hole 306 can reduce weight, thereby reducing the weight of the first main body 202 and the second main body 303 respectively, thus reducing the overall weight of the battery management system bracket assembly 1 and achieving a lightweight design.
