Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0041] Please refer to the attached document. Figures 1-4 This utility model provides an integrated busbar 100, which is an important component in the battery module for current collection and connection, and is mainly responsible for current transmission and circuit connection between battery cells.

[0042] Please refer to the attached document. Figures 1-4 In this application, the integrated busbar 100 includes a module plate 10, a diaphragm 20, a heat sink 30, and a cooling fan 40; the module plate 10 is provided with a heat dissipation pipe 10a; the diaphragm 20 is pressed against the upper and lower side walls of the module plate 10; the heat sink 30 is disposed on the lower side of the module plate 10 and exchanges heat with the module plate 10; the cooling fan 40 is disposed on one side of the module plate 10, and during operation, the cooling fan 40 draws heat from the heat dissipation pipe 10a and extracts heat from the module plate 10 to the heat sink 30; the heat sink 30... The 0 further diffuses heat to achieve heat dissipation of the module board 10, avoiding heat accumulation in the module board 10, ensuring rapid heat dissipation, and preventing heat retention in the internal space of the module board 10. The tight-fitting structure of the diaphragm 20 further restricts heat accumulation inside the module board 10, preventing thermal pressure bulging caused by overheating, avoiding internal separation or bulging of the integrated busbar 100, extending the service life of the integrated busbar 100, and improving the stability and operating efficiency of the battery module.

[0043] Please refer to the attached document. Figures 1-3 In this application, the module board 10 serves as a supporting component of the integrated busbar 100, and is used to support the diaphragm 20, the heat sink 30, and the cooling fan 40. The module board 10 is provided with a heat dissipation pipe 10a; the heat dissipation pipe 10a is used for heat flow.

[0044] Please refer to the attached document. Figures 1-3 In this application, the diaphragm 20 is pressed against the upper and lower sidewalls of the module plate 10; the tight fit of the diaphragm 20 further restricts the accumulation of heat inside the module plate 10.

[0045] Please refer to the attached document. Figures 1-3The diaphragm 20 includes an upper diaphragm 21 and a lower diaphragm 22, which are respectively attached to the upper and lower sidewalls of the module plate 10. The tight fit between the upper and lower diaphragms 21 and 22 and the upper and lower sidewalls of the module plate 10 further restricts heat accumulation inside the module plate 10. Both the upper and lower diaphragms 21 and 22 are coated with a waterproof coating to achieve a waterproof effect on the module plate 10.

[0046] Please refer to the attached document. Figure 1 and 4 In this embodiment, the heat sink 30 is disposed on the lower side of the module plate 10 and exchanges heat with the module plate 10 to facilitate the conduction of heat from the module plate 10 to the heat sink 30. Optionally, the heat sink 30 is a nylon mesh plate.

[0047] Please refer to the attached document. Figure 1 and 4 In this application, the cooling fan 40 is located on the lower side of the module board 10. During operation, the cooling fan 40 draws heat from the heat dissipation pipe 10a and removes heat from the module board 10 to the heat dissipation plate 30. The heat dissipation plate 30 further diffuses the heat to achieve the heat dissipation effect of the module board 10, preventing heat from accumulating in the module board 10 and ensuring rapid heat dissipation. This also prevents heat from lingering in the internal space of the module board 10. The tight-fitting structure of the diaphragm 20 further restricts the accumulation of heat inside the module board 10, preventing thermal pressure cavitation caused by overheating. This also prevents internal separation or cavitation of the integrated busbar 100, extends the service life of the integrated busbar 100, and improves the stability and operating efficiency of the battery module.

[0048] Please refer to the attached document. Figure 1 and 3 The module board 10 is provided with multiple air holes 10b, which are arranged opposite to the heat dissipation end of the cooling fan 40. The multiple air holes 10b form heat dissipation pipes 10a of the module board 10, so that the cooling fan 40 can quickly conduct heat through the multiple air holes 10b to the heat sink 30, thereby facilitating further heat diffusion from the heat sink 30 and ensuring rapid heat dissipation. At the same time, the insulating frame formed on both sides of the heat sink 30 guides the heat and prevents heat from lingering in the internal space of the module board 10.

[0049] Please refer to the attached document. Figure 1 The module board 10 is provided with multiple busbars 11, which are arranged adjacent to each other. The vent 10b is located between two adjacent busbars 11 and is opened in the module board 10. The vent 10b extends through the module board 10 in the vertical direction so that the heat of the module board 10 can be gathered through the multiple busbars 11, thereby facilitating the flow of the gathered heat to the heat sink 30 through the vent 10b, ensuring the concentration of heat.

[0050] Please refer to the attached document. Figure 1 The heat sink 30 is detachably connected to the module plate 10 so that the heat sink 30 can be connected to or detached from the module plate 10. When the heat sink 30 or the module plate 10 needs to be replaced or repaired, the heat sink 30 or the module plate 10 can be removed separately for replacement or maintenance without disassembling other parts. The module plate 10 will not loosen or shift during disassembly, reducing misoperation during maintenance and improving the convenience of replacing or repairing the heat sink 30 or the module plate 10.

[0051] Please refer to the attached document. Figure 1 The heat sink 30 and the module board 10 are connected by bolts, so that the heat sink 30 can be detachably connected to the module board 10 by bolts, and the heat sink 30 or the module board 10 can be disassembled by removing the bolts.

[0052] Please refer to the attached document. Figures 1-3 The integrated busbar 100 also includes multiple feet 50, which are all connected to the module plate 10 and distributed at the four corners of the module plate 10, so that the multiple feet 50 can be fixed to the four corners of the module plate 10, thereby facilitating the multiple feet 50 to protrude from the four corners of the module plate 10. The integrated busbar 100 also includes corner brackets 60, which are located on the outside of the module plate 10 and support the corresponding feet 50, so that the corner brackets 60 can support the module plate 10 through the feet 50.

[0053] Please refer to the attached document. Figure 1 The integrated busbar 100 also includes a bumper 70, which is connected to an elastic buffer 71. Angle brackets 60 are housed within the bumper 70 and are elastically contacted by the elastic buffer 71, allowing the bumper 70 to connect to the angle brackets 60 via the elastic buffer 71. When the bumper 70 is subjected to an impact, it slightly displaces, buffering the impact force and dispersing it around the angle brackets 60, thus achieving the anti-collision effect of the module board 10 and ensuring the safe operation of the integrated busbar 100.

[0054] Please refer to the attached document. Figure 1 The elastic buffer 71 includes an elastic portion 711 and a contact portion 712. The contact portion 712 contacts the outer wall of the corner seat 60, so that the elastic buffer 71 can be connected to the outer wall of the corner seat 60 through the contact portion 712. The two ends of the elastic portion 711 are elastically connected to the anti-collision device 70 and the contact portion 712, respectively, and an elastic force is applied to the contact portion 712, so that the elastic buffer 71 can be elastically connected to the corner seat 60 through the elastic portion 711. When an external impact force contacts the anti-collision device 70, the elastic portion 711 is compressed relative to the corner seat 60, so that the elastic portion 711 buffers the external impact force, thereby facilitating the dispersion of the external impact force and achieving the anti-collision effect of the corner seat 60.

[0055] Please refer to the attached document. Figure 1 Multiple elastic buffers 71 are provided, with two adjacent elastic buffers 71 acting on two adjacent outer side walls of the corner seat 60. By arranging multiple elastic buffers 71, the elastic buffers 71 are positioned around the corner seat 60 at different locations, ensuring that the corner seat 60 achieves a collision protection effect at different locations, thereby ensuring the circumferential collision protection effect of the corner seat 60. Optionally, the anti-collision device 70 is arranged in an L-shape to facilitate the adaptation of the inner side wall of the anti-collision device 70 to the outer side wall of the corner seat 60.
