Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing, specifically a multifunctional integrated wiring harness board suitable for battery modules. Background Technology

[0002] With the rapid development of power battery modules towards higher energy density and higher integration, the requirements for the accuracy and real-time performance of cell status monitoring (such as voltage and temperature) by the Battery Management System (BMS) are increasing. As the core carrier connecting the battery cells and the BMS, the wiring harness board needs to integrate voltage acquisition wiring harnesses, temperature sensors, insulation monitoring circuits, and mechanical fixing structures. Its performance directly affects the safety, reliability, and energy management efficiency of the module. Existing traditional solutions adopt a separate design of "wiring harness + PCB board + structural components." The wiring harness board of the battery module only has wiring harness acquisition function, which is limited in functionality. Furthermore, the wiring harness board lacks components for connection and limiting with the battery module, and does not have aluminum busbar installation limiting functions. This results in low connection stability between the wiring harness board and the battery module, poor compatibility, and in severe cases, mutual interference between their functions, reducing the stability and lifespan of the battery module. Therefore, there is an urgent need for a multi-functional integrated wiring harness board that can stably connect with the battery module, increasing the overall integrity and stability of the battery module.

Limiting holes, busbar mounting holes, and pressure relief holes are respectively cut out on the plate. Reinforcing ribs are fixed on the plate, and wire passage holes are opened through the reinforcing ribs. The plate is also provided with busbar limiting posts and wiring harness binding points.

[0006] In a further embodiment, the limiting holes are evenly distributed at both ends of the plate, and the limiting holes at each end are evenly distributed on both sides of the plate.

[0012] In a further embodiment, at least two reinforcing plates perpendicular to the plate are fixed around the sidewall of the pressure relief hole.

[0013] In a further embodiment, the reinforcing ribs are distributed on both sides and the middle of the plate, and each reinforcing rib is the same length as the plate.

[0022] Compared with existing technologies, the advantages of this multifunctional integrated wire harness board are:

[0023] I. This utility model utilizes the limiting holes in the wire harness plate to fix the wire harness plate to the battery module, thereby limiting the position of the wire harness plate on the battery module. A wire harness bundling point is provided in the middle of the wire harness plate for easy fixing of the wire harness onto the wire harness plate. The wire harness plate also has a pressure relief hole, which ensures that the pressure relief of the battery cell is not affected when the cell triggers thermal runaway and releases a large amount of gas. Wire passage holes are provided on both sides of the wire harness plate for convenient and flexible arrangement of the wire harness and fixation to the wire harness plate. The wire harness plate has busbar limiting posts, each pair of which can limit the position of one busbar, allowing for flexible placement of busbars according to different battery cells.

[0024] II. In this utility model, the wire harness plate body is made of ABS+PC composite material. When the module is subjected to force and deformation, the wire harness plate has a certain degree of flexibility to prevent the wire harness plate from being damaged due to deformation. The wire harness plate has good insulation effect to prevent the wire harness plate from directly contacting the battery cell and forming a short circuit. The partition has good heat insulation performance to prevent temperature transfer caused by local temperature rise and generate the risk of thermal runaway. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Implementation, for example Figure 1-2 As shown, this embodiment provides a multi-functional integrated wiring harness board suitable for battery modules, including a long rectangular plate 1. The plate 1 has a limit hole 2, a busbar mounting hole 3 and a pressure relief hole 4 respectively. A reinforcing rib 5 is fixed on the plate 1. A wire passage hole 6 is opened through the reinforcing rib 5. The plate 1 is also provided with a busbar limit post 7 and a wiring harness binding point 8.

[0030] The limiting holes 2 are evenly distributed at both ends of the plate 1, with each end having at least eight limiting holes 2 evenly distributed on both sides of the plate 1. The plate 1 containing the limiting holes 2 is thickened. In this embodiment, the limiting holes 2 of the wire harness plate can be used to fix the wire harness plate 1 to the battery module 10, thereby limiting the position of the wire harness plate 1 on the battery module 10. The thickening of the plate 1 containing the limiting holes 2 can also enhance the stability and firmness of the connection between the wire harness plate 1 and the battery module 10.

[0031] The busbar mounting holes 3 are evenly distributed on both sides of the plate 1, and each side has busbar mounting holes 3 distributed along the long axis of the plate 1, with no fewer than 26 busbar mounting holes 3. The busbar limiting posts 7 are divided into several groups, and each group of busbar limiting posts 7 is located between adjacent busbar mounting holes 3 on each side, with no fewer than 2 posts 7 in each group. In this embodiment, the busbar mounting holes 3 facilitate the installation of busbars on the battery module 10, and each pair of busbar limiting posts 7 can limit the position of one busbar, allowing for flexible placement of busbars according to different battery cells.

[0032] The pressure relief holes 4 are evenly distributed along the long axis of the plate 1 in the middle of the plate 1, and the number of pressure relief holes 4 is not less than 13. The wire harness binding points 8 are divided into several groups, and each group of wire harness binding points 8 is located between adjacent pressure relief holes 4, and the number of wire harness binding points 8 in each group is not less than 2. There are not less than two reinforcing plates 9 perpendicular to the plate 1 fixed around the side wall of the pressure relief holes 4. In this embodiment, the pressure relief holes 4 on the plate 1 can not affect the pressure relief of the battery cell when the cell triggers thermal runaway and releases a large amount of gas. The reinforcing plates 9 can enhance the strength of the pressure relief holes 4, so that they can adapt to the sudden increase in pressure during exhaust. The wire harness binding points 8 facilitate the organization of the wire harness, making it neat and orderly for easy maintenance, and also avoids the wire harness from being haphazardly tangled and causing short circuits.

[0033] The reinforcing ribs 5 are distributed on both sides and the middle of the plate 1, and each reinforcing rib 5 is the same length as the plate 1. Wiring holes 6 are evenly distributed on the reinforcing ribs 5 on both sides of the plate 1, with no fewer than 7 wiring holes 6 on each side. In this embodiment, the reinforcing ribs 5 can significantly increase the strength of the plate 1, thus significantly increasing the overall stability when connected to the battery module 10; the wiring holes 6 facilitate flexible arrangement of the wire harness and fixation to the wire harness plate.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
