[0058] As described in the background section, during the assembly of new energy vehicle battery packs, components such as cell modules, battery management system modules, and integrated busbar assemblies need to be assembled into the battery pack housing. The housing includes a bracket and a top cover. The top cover is placed on the bracket and together with the bracket, forms an installation cavity for placing the various components. The components are directly fixed to the bracket by bolts. However, directly fixing the components to the base plate with bolts compromises the integrity of the bracket, thereby reducing the strength of the housing.

The support member and the side plate together form an installation cavity. The support member is provided with a first installation area and a second installation area. The first installation area is used to install the battery management system module, and the second installation area is used to install a partial integrated busbar assembly. The battery management system module and the partial integrated busbar assembly are installed into the installation cavity. By providing a support member with a first installation area and a second installation area, the battery management system module and the partial integrated busbar assembly are installed into the installation cavity, avoiding direct connection between the battery management system module and the partial integrated busbar assembly and the base plate, protecting the integrity of the base plate, indirectly improving the support strength of the bracket mechanism, and thus improving the connection stability of the components in the battery pack.

[0060] It should be noted that, Figures 1 to 7 The diagram shows a simplified representation of the bracket mechanism, housing, and components within the battery pack. The specific structures of the remaining components in the bracket mechanism, housing, and battery pack are not limited to these details. Figures 1 to 7 of examples.

[0061] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings:

[0062] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this application embodiment provides a bracket mechanism for a housing, including a base plate 100, a side plate 200, and a support member 300.

[0063] The side plate 200 is arranged around the periphery of the base plate 100.

[0064] The support member 300 and the side plate 200 are located on the same side of the base plate 100.

[0065] The support member 300 and the side plate 200 together form an installation cavity.

[0066] The support member 300 is provided with a first mounting area 310 and a second mounting area 320.

[0067] The first installation area 310 is used to install the battery management system module 10, and the second installation area 320 is used to install the partially integrated busbar assembly 20.

[0068] The battery management system module 10 and part of the integrated busbar assembly 20 are installed into the mounting cavity.

[0069] In the above embodiment, by providing a support member 300 with a first mounting area 310 and a second mounting area 320, the battery management system module 10 and part of the integrated busbar assembly 20 are installed into the mounting cavity, which avoids the battery management system module 10 and part of the integrated busbar assembly 20 being directly connected to the base plate 100, protects the integrity of the base plate 100, indirectly improves the support strength of the bracket mechanism, and thus improves the connection stability of each component in the battery pack.

[0070] In addition, the base plate 100 and the support member 300 form a double-layer structure, which further improves the strength and thus improves the connection stability of the various components in the battery pack.

[0071] It should be noted that the base plate 100 is a one-piece molded structure, which helps to improve the strength of the base plate 100. The support member 300 can be plasticized as needed. The connection between the support member 300 and the base plate 100 can be welding or bonding. Of course, in some cases, the support member 300 can also be screwed to the base plate 100.

[0072] In one possible implementation, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it also includes at least one partition beam 400.

[0073] The partition beam 400 is connected to the support member 300. Here, the partition beam 400 can be screwed to the support member 300 to divide the mounting cavity into an electrical area and a battery cell area.

[0074] The first installation area 310 is located within the electrical area, and the second installation area 320 is located within the battery cell area.

[0075] In the above embodiments, reference is made to Figure 2 As shown, two partition beams 400 can be provided. The partition beams 400 and the side plate 200 together divide the mounting cavity into cell areas, and the number of cell areas is set to at least two. In this way, cell modules 30 can be installed in the cell areas, which can increase the number of cell modules 30 and improve the capacity of the battery pack.

[0076] In addition, the partition beam 400 divides the mounting cavity into an electrical area and a battery cell area, which can prevent the components in the electrical area from interfering with each other and the components in the battery cell area. By dividing the area into zones, it is convenient to position and install the components in each zone and improve the working stability of each component.

[0077] In one possible implementation, refer to Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, it also includes at least one support beam 500.

[0078] The support beam 500 is connected to the support member 300, and the support beam 500 can be screwed to the support member 300.

[0079] One end of the support beam 500 is connected to the side plate 200, and the other end of the support beam 500 is connected to the partition beam 400.

[0080] The support member 300, side plate 200, partition beam 400 and support beam 500 together enclose the first installation area 310.

[0081] The support beam 500 is used to connect to the battery management system module 10.

[0082] It should be noted that the battery management system module 10 is existing technology in the relevant field, and it typically has a protective shell for installation, with the support beam 500 screwed to the protective shell.

[0083] In the above embodiments, such as Figure 3 As shown, the partition beam 400 and the support beam 500 have an angle in their length directions. Specifically, the partition beam 400 extends along the length direction of the cell module 30, and the support beam 500 extends along the width direction of the cell module 30.

[0084] In the above embodiment, by setting the support beam 500, the support member 300, side plate 200, partition beam 400, and support beam 500 together enclose the first installation area 310. This allows the battery management system module 10 to be installed into the installation cavity. The support beam 500 also has a positioning and limiting function for the installation of the battery management system module 10, facilitating the rapid installation of the battery management system module 10.

[0085] Meanwhile, the mounting points of the battery management system module 10 and the battery pack are set on the support beam 500, avoiding the traditional direct connection on the base plate 100, which helps to protect the integrity of the base plate 100 and improve the strength of the base plate 100.

[0086] In one example, two support beams 500 can be provided. The support member 300, the side plate 200, the partition beam 400 and the two support beams 500 together enclose the first installation area 310, which can improve the stability of the first installation area 310.

[0087] In one possible implementation, to further improve the installation stability of the battery management system module 10, at least one support frame 600 is also included.

[0088] The support frame 600 is connected to the support member 300, and the support frame 600 can be screwed to the support member 300.

[0089] The support frame 600 is used to fix the battery management system module 10.

[0090] In the above embodiments, the support frame 600 can support the battery management system module 10. In another implementation, the support frame 600 can also be connected to the battery management system module 10, which is equivalent to providing more connection points for the battery management system module 10 and improving the installation stability of the battery management system module 10. In addition, by setting up the support frame 600, the battery management system module 10 can be cushioned to prevent damage caused by impact.

[0091] In one possible implementation, at least one first protrusion 700 is also included.

[0092] The first protrusion 700 is connected to the support member 300, which is either screwed or welded to the support member 300.

[0093] The first protrusion 700 is set inside the mounting cavity.

[0094] The first protruding strip 700, the support member 300, and the side plate 200 together form the second installation area 320.

[0095] Partially integrated busbar assembly 20 is clamped in the second installation area 320.

[0096] In the above embodiments, the integrated busbar assembly 20 includes a slave plate, which is used to collect parameters of each cell module 30. The first protrusion 700, the support member 300, and the side plate 200 together form a second mounting area 320 for clamping the slave plate in the second mounting area 320. By setting the second mounting area 320 to clamp the slave plate, the installation of the slave plate has a rapid positioning effect and can improve the installation stability of the slave plate. In specific implementation, in order to further improve the stability of the slave plate, after the slave plate is clamped in the second mounting area 320, it can also be screwed to the first protrusion 700.

[0097] In one possible implementation, refer to Figure 4 , Figure 5 and Figure 7 As shown, it also includes at least one second protrusion 800.

[0098] The second protrusion 800 is connected to the support member 300. Here, the second protrusion 800 can be screwed or welded to the support member 300.

[0099] The second protrusion 800 has a third mounting position 330, which is used to connect with the serpentine plate 40 of the battery cell module 30.

[0100] In the specific implementation of the above embodiments, the second protrusion 800 can be arranged parallel to the first protrusion 700 to improve the aesthetics of the internal mounting cavity of the battery pack. In related technologies, the cell module 30 has a serpentine plate 40, which is used to fix the cells in the cell module 30. By providing the second protrusion 800 on the support member 300 and connecting the serpentine plate 40 to the second protrusion 800, the stability of the serpentine plate 40 is improved. This indirectly improves the stability of the cell module 30.

[0101] Specifically, there are two second protrusions 800, which are respectively located at both ends of the serpentine plate 40 and connected to both ends of the serpentine plate 40, thereby further improving the stability of the serpentine plate 40.

[0102] In one possible implementation, in order to improve the stability of the partition beam 400, at least one clearance groove is provided on the partition beam 400, the first protrusion 700 and the second protrusion 800 pass through the clearance groove, and the partition beam 400 is connected to the first protrusion 700 and the second protrusion 800 at the clearance groove position.

[0103] In one possible implementation, the support member has a flange on its 300 circumferential side.

[0104] The flange is connected to the side wall of the side panel 200.

[0105] Specifically, the flange is integrally formed with the support member 300, which helps to improve the strength of the support member 300. The flange is connected to the side wall of the side plate 200, specifically the inner side wall of the side plate 200. By setting the flange, the support member 300 and the side plate 200 can be smoothly transitioned, and the flange has a certain buffering effect, further improving the stability of the support member 300.

[0106] In addition, by setting the flange, the installation of the support 300 is guided, which facilitates the quick installation of the support 300.

[0107] In one possible implementation, refer to Figure 4 and Figure 6 As shown, there is at least one reinforcing rib 900 between the flange and the support member 300.

[0108] Here, the connection strength between the flange and the support member 300 is further improved by setting reinforcing ribs 900. Specifically, multiple reinforcing ribs 900 are provided, and the multiple reinforcing ribs 900 are arranged along the periphery of the support member 300.

[0109] Of course, a clearance notch needs to be provided on the flange to accommodate the charging port.

[0110] In one possible implementation, this application also provides a housing, including a top cover and the aforementioned bracket mechanism, with the top cover covering the bracket mechanism. The specific structure of the bracket mechanism has already been described above and will not be repeated here.

[0111] By providing the aforementioned bracket mechanism, the components inside the battery pack can be prevented from being directly connected to the base plate 100, which helps to protect the integrity of the base plate 100 and indirectly improves the strength of the housing.

[0112] This application also provides a battery pack, including a body and the aforementioned housing.

[0113] The main body is housed within the casing. It should be noted that the main body refers to existing technology for related components within a battery pack in the relevant field, and may include the cell module 30, the battery management system module 10, or the integrated busbar assembly 20, etc. Further details will not be elaborated upon here.

[0114] In the above embodiments, the strength and stability of the battery pack can be improved by providing the aforementioned casing.

[0115] The implementation principle of the bracket mechanism, housing, and battery pack in this application embodiment is as follows: The bracket mechanism, housing, and battery pack provided in this application embodiment include a base plate 100, a side plate 200, and a support member 300. The side plate 200 surrounds the periphery of the base plate 100, and the support member 300 and the side plate 200 are disposed on the same side of the base plate 100. The support member 300 and the side plate 200 together form an installation cavity. The support member 300 is provided with a first installation area 310 and a second installation area 320. The first installation area 310 is used to install the battery management system module 10, and the second installation area 320 is used to install the battery management system module 10. Zone 320 is used to install a partial integrated busbar assembly 20, so as to install the battery management system module 10 and the partial integrated busbar assembly 20 into the mounting cavity. By setting a support member 300 with a first mounting zone 310 and a second mounting zone 320, the battery management system module 10 and the partial integrated busbar assembly 20 are installed into the mounting cavity, avoiding direct connection between the battery management system module 10 and the partial integrated busbar assembly 20 and the base plate 100, protecting the integrity of the base plate 100, indirectly improving the support strength of the bracket mechanism, and thus improving the connection stability of each component in the battery pack.
