[0046] 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 of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0047] As described in the background section, in existing battery module integration assemblies, conventional flexible circuit board assemblies are typically assembled using a direct bonding method. The contact between multiple flexible circuit board assemblies can easily lead to wear and tear on each other. The safety and stability of battery module integration assemblies need to be improved, as does the overall efficiency of the battery module.

[0048] To address the aforementioned technical problems, a first aspect of this application provides a battery module integration assembly. This assembly includes at least two first flexible circuit boards, a second flexible circuit board, an adapter, and a base plate. The at least two first flexible circuit boards, the second flexible circuit board, and the adapter are arranged side-by-side in a first direction. The first and second flexible circuit boards are stacked in a second direction. The adapter is located between the first and second flexible circuit boards, and there are gaps between the adapter and both boards in the second direction. The at least two second flexible circuit boards are located on the base plate, with the first and second directions perpendicular to each other. Thus, by incorporating the adapter in the battery module integration assembly, and ensuring that the adapter between the first and second flexible circuit boards has gaps between it and both boards, the assembly provides both cable heat dissipation and insulation.

[0049] A second aspect of this application provides a battery pack. The battery pack includes a plurality of battery modules and at least one battery module integration component. The battery module integration component is located on top of the battery modules. This combination of battery modules and battery module integration component, with the integration component positioned on top of the battery modules, allows for compatibility between the battery modules and the integration component, thereby improving the overall performance of the battery pack.

[0050] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, 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 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.

[0051] This application provides a battery module integration assembly and a battery pack. An adapter is provided in the battery module integration assembly, such that the adapter, located between a first flexible circuit board and a second flexible circuit board, has gaps with both boards. This serves both as a heat dissipation function for the wiring and as an insulating barrier. The specific structure of the battery module integration assembly and battery pack provided in this application embodiment will be described below with reference to the accompanying drawings.

[0052] refer to Figure 1This application provides a battery module integration assembly 100 in a first aspect. The battery module integration assembly 100 may include a first flexible circuit board 200, a second flexible circuit board 300, an adapter 400, and a base plate 500. In one possible implementation, the number of the first flexible circuit board 200, the second flexible circuit board 300, and the adapter 400 may be at least two. This application embodiment does not limit the number of the first flexible circuit board 200, the second flexible circuit board 300, and the adapter 400. In this application embodiment, an example is given with two of each of the first flexible circuit board 200, the second flexible circuit board 300, and the adapter 400. Figure 2 As shown, the two first flexible circuit boards 200, the second flexible circuit board 300 and the adapter 400 can all be arranged side by side in the first direction, and the first flexible circuit board 200 and the second flexible circuit board 300 can also be stacked in the second direction. The first flexible circuit board 200 can be located on the second flexible circuit board 300, and the two second flexible circuit boards 300 can both be located on the base plate 500.

[0053] It should be noted that, for ease of description, in this embodiment, the first direction can be the length direction of the base plate 500, i.e. Figure 1 The x-direction. The second direction can be the thickness direction of the base plate (500mm), i.e. Figure 1 The y-direction in the equation. The first and second directions are perpendicular.

[0054] Continue to refer to Figure 1 as well as Figure 2 Based on the above embodiments, the adapter 400 can be located between the first flexible circuit board 200 and the second flexible circuit board 300, so that the first flexible circuit board 200, the adapter 400, and the second flexible circuit board 300 are stacked sequentially in the second direction. In one possible implementation, the adapter 400 and the first flexible circuit board 200 and the second flexible circuit board 300 can each have a gap in the second direction. Thus, by providing the adapter 400 between the first flexible circuit board 200 and the second flexible circuit board 300, and ensuring that the adapter 400 has gaps with both the first flexible circuit board 200 and the second flexible circuit board 300 in the second direction, the first flexible circuit board 200 and the second flexible circuit board 300 do not contact each other, avoiding mutual wear. It is understood that the gaps between the adapter 400 and the first flexible circuit board 200 and the second flexible circuit board 300 in the second direction serve both as heat dissipation for the wiring and as good insulation.

[0055] Continue to refer to Figure 2Based on the above embodiments, each adapter 400 may have a groove 410. This groove 410 allows the first flexible circuit board 200 to be placed, thus adapting the groove 410 to the first flexible circuit board 200. It is understood that providing the groove 410 on the adapter 400 can increase the structural rigidity and strength of the adapter 400, giving it good mechanical properties, making it less prone to bending, and facilitating assembly with the first flexible circuit board 200. Furthermore, it can reduce material usage, thereby achieving weight reduction and lower costs.

[0056] refer to Figure 1 , Figure 2 ,as well as Figure 3 Based on the above embodiments, the first flexible circuit board 200 and the second flexible circuit board 300 can be arranged in parallel. The first flexible circuit board 200 may have a first through hole 210, and correspondingly, the adapter 400 has an adapter hole 420. In one possible implementation, the number of first through holes 210 and adapter holes 420 can be multiple; this application embodiment does not limit the number of first through holes 210 and adapter holes 420. In this application embodiment, multiple first through holes 210 are sequentially arranged along a first direction on the first flexible circuit board 200, and multiple adapter holes 420 are sequentially arranged along the first direction on the adapter 400, and the first through holes 210 and adapter holes 420 can be one-to-one corresponding. It is understood that opening the first through hole 210 on the first flexible circuit board 200 can improve the heat dissipation performance of the first flexible circuit board 200. By increasing air circulation, opening the first through hole 210 can help reduce the temperature on the first flexible circuit board 200 and prevent overheating.

[0057] Continue to refer to Figure 2Based on the above embodiments, a second through hole 310 may be formed on the second flexible circuit board 300, and a positioning hole 510 may be formed on the base plate 500. In one possible implementation, the number of second through holes 310 and positioning holes 510 may be plurality, and this application embodiment does not limit the number of second through holes 310 and positioning holes 510. In this application embodiment, a plurality of second through holes 310 are sequentially arranged on the second flexible circuit board 300 along a first direction, and a plurality of positioning holes 510 are sequentially arranged on the base plate 500 along a first direction, and the second through holes 310 and positioning holes 510 may correspond one-to-one. It is understood that the first through hole 210, the adapter hole 420, the second through hole 310, and the positioning hole 510 are all arranged in a one-to-one correspondence. The second through-hole 310 on the second flexible circuit board 300 can improve its heat dissipation performance. By increasing airflow, the second through-hole 310 can help reduce the temperature on the second flexible circuit board 300 and prevent overheating. The first through-hole 210, the adapter hole 420, the second through-hole 310, and the positioning hole 510 work together to improve the circuit performance of the first flexible circuit board 200 and the second flexible circuit board 300.

[0058] Based on the above embodiments, the adapter 400 can be made of an insulating material. It is understood that, in one possible implementation, the adapter 400 can be a plastic product manufactured by a vacuum forming process, possessing insulating properties, capable of separating the first flexible circuit board 200 and the second flexible circuit board 300, and offering lower cost and higher production efficiency.

[0059] Based on the above embodiments, the first flexible circuit board 200 and the adapter 400 are fixedly connected, thereby forming a whole. In one possible implementation, the first flexible circuit board 200 and the adapter 400 are fixedly connected by riveting, which facilitates precise positioning between the first flexible circuit board 200 and the adapter 400.

[0060] Continue to refer to Figure 2 Based on the above embodiments, each first flexible circuit board 200 may have a plug-in portion 220 at one end, and a first plug-in terminal 230 at the other end. Additionally, the second flexible circuit board 300 may have a second plug-in terminal 320 at the end facing away from the plug-in portion 220. It is understood that the plug-in portion 220 can be used to plug into the first plug-in terminal 230 and / or the second plug-in terminal 320, thereby enabling a plurality of battery modules 700 having a battery module integration assembly 100 to be plugged into the first plug-in terminal 230 and / or the second plug-in terminal 320 via the plug-in portion 220, thereby achieving electrical connection between the battery modules 700.

[0061] refer to Figure 4 This application provides a battery pack 600 in a second aspect. The battery pack 600 may include a battery module 700 and the aforementioned battery module integration assembly 100. In one possible implementation, the number of battery modules 700 and battery module integration assemblies 100 can be multiple; this application does not limit the number of battery modules 700 and battery module integration assemblies 100. In this application embodiment, each battery module integration assembly 100 can be located on top of the battery module 700. The base plate 500 of the battery module integration assembly 100 can be fixed to the top of the battery module 700, thereby achieving a fixed connection between the battery module 700 and the battery module integration assembly 100. By combining the battery module 700 and the battery module integration assembly 100, the battery module integration assembly 100 is laid on top of the battery module 700, thereby adapting the battery module 700 and the battery module integration assembly 100 to each other and improving the overall performance of the battery pack 600.

[0062] Based on the above embodiments, in one possible implementation, the insertion portion 220 of the first flexible circuit board 200 of one battery module integration assembly 100 can be connected to the first insertion end 230 of the first flexible circuit board 200 of an adjacent battery module integration assembly 100, thereby realizing an electrical connection between the battery modules 700. In other embodiments, depending on the different requirements of the battery pack 600, the insertion portion 220 of the first flexible circuit board 200 of one battery module integration assembly 100 can be connected to the second insertion end 320 of the second flexible circuit board 300 of an adjacent battery module integration assembly 100, thereby also realizing an electrical connection between the battery modules 700.

[0063] Continue to refer to Figure 4 Based on the above embodiments, the battery module 700 may further include a vent valve 800. In one possible implementation, the number of vent valves 800 can be several; however, this application embodiment does not limit the number of vent valves 800. In this application embodiment, combined with... Figure 1As can be seen, the vent valve 800 corresponds to the second through hole 310 of the second flexible circuit board 300 of the battery module integration assembly 100, and the dimensions of the first through hole 210, the adapter hole 420, the second through hole 310, and the positioning hole 510 of the battery module integration assembly 100 can all be greater than or equal to the dimensions of the vent valve 800. It is understood that the vent valve 800 can be used to regulate the internal pressure of the battery module 700. When the battery module 700 generates gas during charging and discharging, the vent valve 800 can release excess gas to prevent excessive internal pressure, thereby avoiding safety hazards to the battery module 700. The arrangement of the first through hole 210, the adapter hole 420, the second through hole 310, and the positioning hole 510 of the battery module integration assembly 100 promotes airflow, ensuring that the gas released by the vent valve 800 can be smoothly discharged from the outside of the battery module 700, thus providing auxiliary heat dissipation.

[0064] In this embodiment, the battery module integration assembly 100 provided in this application includes an adapter 400, such that the adapter 400 located between the first flexible circuit board 200 and the second flexible circuit board 300 has gaps with both the first flexible circuit board 200 and the second flexible circuit board 300. This serves both as a heat dissipation function for the ribbon cable and as an insulating barrier.
