[0040] Example 1

[0041] like Figures 1 to 6 As shown, this embodiment provides a module bracket. The module bracket 10 includes a bracket body 11 and an aluminum busbar 15. The aluminum busbar 15 is integrated with the bracket body 11. The aluminum busbar 15 is used for welding connection with the positive and / or negative terminals of the battery cell module 20. By integrating first and then assembling, the existing assembly process is simplified and the assembly efficiency is improved.

[0042] In some embodiments, the bracket body 11 is provided with at least one mounting window 12 and at least one acquisition window 13. The mounting window 12 is surrounded by a first flange 121. An aluminum busbar 15 is connected to the first flange 121 and is disposed corresponding to the mounting window 12. Specifically, the aluminum busbar 15 is disposed inside the first flange 121. The acquisition window 13 is surrounded by a second flange 131. The second flange 131 is provided with a first wire groove 132. The bracket body 11 also forms at least one wiring channel 14 for placing the acquisition wire harness. The first wire groove 132 communicates with the wiring channel 14. The acquisition window 13 serves as a sampling point for assembling an acquisition probe.

[0043] In the above embodiment, by setting an installation window 12 and a data acquisition window 13 on the bracket body 11, and setting a first flange 121 and a second flange 131 around the installation window 12 and the data acquisition window 13 respectively, the aluminum busbar 15 and the data acquisition probe are pre-assembled and fixed. At the same time, a wiring channel 14 is also set on the bracket body 11 to realize the arrangement and fixation of the data acquisition harness, so as to connect the aluminum busbar 15 and the data acquisition probe and assemble them into a whole. Finally, the assembled whole is docked and assembled with the battery cell module 20, and the aluminum busbar 15 is welded to the positive or negative terminal of the battery cell module 20.

[0044] Therefore, this embodiment simplifies the battery module assembly process and improves work efficiency by adopting the method of integration before assembly. At the same time, the method of integration before assembly can effectively reduce the intensity of manual labor and labor costs.

[0045] In some implementations, since battery modules are typically composed of multiple cells connected in series or parallel, this embodiment uses multiple mounting windows 12, acquisition windows 13, and wiring channels 14 to increase the sampling points of the module bracket 10, making data acquisition more comprehensive, increasing the number of BMS monitoring points, ensuring that the status of the battery module can be fully detected, and making the battery module safer to use.

[0046] In some embodiments, to ensure the stability of the aluminum busbar 15 after installation, the inner wall of the first flange 121 is provided with a step 122 for supporting the aluminum busbar 15, which can provide good support and fixation for the aluminum busbar 15, ensure the reliability of the subsequent connection between the aluminum busbar 15 and the battery cell, and avoid breakage and loose connection.

[0047] In some embodiments, to further ensure the reliability of the connection between the aluminum busbar 15 and the battery cell, the first flange 121 is provided with a clearance groove 123, and the bracket body 11 is also provided with a corresponding snap-fit ​​member 16 for the clearance groove 123. The aluminum busbar 15 and the snap-fit ​​member 16 snap-fit ​​each other, and the snap-fit ​​member 16 cooperates with the step 122 to lock the aluminum busbar 15, so that the aluminum busbar 15 and the bracket body 11 form an integral structure after assembly, and there will be no phenomenon of falling off or shifting during the connection with the battery cell, thereby ensuring the reliability of the connection between the aluminum busbar 15 and the battery cell.

[0048] In some embodiments, each mounting window 12 is provided with at least two snap-fit ​​pieces 16, and the at least two snap-fit ​​pieces 16 are arranged opposite each other to ensure the firmness and reliability of the assembly between the aluminum busbar 15 and the bracket body 11.

[0049] In some embodiments, to facilitate the assembly of the aluminum busbar 15 with the bracket body 11, the snap-fit ​​member 16 includes a deformable portion 161 and a latching portion 162. One end of the deformable portion 161 is connected to the bracket body 11, and the latching portion 162 is located on the side of the deformable portion 161 away from the bracket body 11, extending towards the mounting window 12. Specifically, the latching portion 162 includes a guide surface 162a and a limiting surface 162b. The guide surface 162a is an inclined surface or arc surface inclined towards the mounting window 12, and the limiting surface 162b is parallel to the step 122. Furthermore, a gap is formed between the plane where the limiting surface 162b is located and the step 122, which can accommodate the aluminum busbar 15. Thus, when the aluminum busbar 15 is assembled to the bracket body 11, the aluminum busbar 15 abuts against the guide surface 162a, forcing the deformation part 161 to deform outward of the first flange 121 until the aluminum busbar 15 passes through the guide surface 162a and enters the gap formed between the plane where the limiting surface 162b is located and the step 122. The latching part 162 and the step 122 limit and fix the aluminum busbar 15 from both sides, thereby ensuring the reliability of the subsequent connection between the aluminum busbar 15 and the battery cell.

[0050] In some embodiments, to facilitate the connection between the acquisition harness and the aluminum busbar 15, the first flange 121 is also formed with a second groove 124. The second groove 124 is connected to the wiring channel 14. The acquisition harness passes through the second groove 124 and is then connected to the aluminum busbar 15. In this way, the acquisition probe, the aluminum busbar 15, and the acquisition harness can all be pre-assembled onto the bracket body 11. Finally, the assembly of the battery can be completed by simply welding the aluminum busbar 15 to the battery cell.

[0051] In some embodiments, the bracket body 11 is also provided with reinforcing ribs 17 to improve the structural strength of the entire bracket body 11 and ensure the reliability of the connection between the module bracket 10 and the cell module 20.

[0052] In some embodiments, the reinforcing rib 17 is connected to the outer wall of the first flange 121; and / or the reinforcing rib 17 is connected to the outer wall of the second flange 131, thereby reinforcing the entire module support 10.

[0053] In some embodiments, a limiting strip 141 is provided in the wiring channel 14 to limit and fix the acquisition wire harness, ensuring the neatness and aesthetics of the wiring, reducing the workload of subsequent tidying of the acquisition wire harness, and improving work efficiency; in some embodiments, the limiting strip 141 can be connected to the outer wall of the first flange 121 or the second flange 131.

[0054] In some implementations, there are multiple limiting strips 141 in the wiring channel 14, which are arranged in an alternating manner to prevent the acquisition wire harness from falling off or getting tangled.

The data acquisition probe is located in the data acquisition window 13 and is electrically connected to the data acquisition harness. During assembly, the aluminum busbar 15 is pre-assembled onto the bracket body 11, and the data acquisition harness and data acquisition probe are arranged. Then, the module bracket 10 is connected to the cell module 20 as a whole, and the aluminum busbar 15 is welded to the positive terminal and / or negative terminal of the cell module 20.

The aluminum busbar 15 abuts against the guide surface 162a, forcing the deformation part 161 to deform outward of the first flange 121 until the aluminum busbar 15 passes through the guide surface 162a and enters the gap formed between the plane where the limiting surface 162b is located and the step 122. The aluminum busbar 15 is limited and fixed from both sides by the buckle part 162 and the step 122. Then, the acquisition probe is fixed on the inner side of the second flange 131, and the acquisition cable is used to secure it. Placed within the wiring channel 14, one end of the acquisition harness is connected to the acquisition probe via the first wire groove 132, and the other end is connected to the aluminum busbar 15 via the second wire groove 124, thereby assembling the module bracket into a whole. Then, the entire module bracket is connected to the battery cell module 20, and finally, the aluminum busbar 15 is welded to the positive and / or negative terminals of the battery cell module 20. There is no need to use additional tooling fixtures to position the aluminum busbar 15 and the battery cell module 20, saving labor costs and improving work efficiency.
