[0002] The separator plate is located at the top of the battery pack. It serves to support the wiring harness and separate it from the battery pack. When the separator plate is long, its structural strength decreases, making it prone to bending along its length. Furthermore, directly adding a reinforcing structure increases the size of the separator plate. Therefore, how to increase the structural strength of the separator plate while reducing its volume is a problem that needs to be solved. Utility Model Content

[0063] Figure 1 This is a schematic diagram of the battery module in this embodiment. Figure 2 This is an exploded view of the battery module in this embodiment. Figure 2 Only a portion of the busbar 62 and connector 63 is shown in the image.

[0064] In some implementations, such as Figures 1-2 As shown, the battery module in this embodiment includes an adapter assembly and multiple battery packs 8. The adapter assembly is disposed on top of the multiple battery packs 8 and electrically connected to the battery packs 8. The adapter assembly is used to connect to the electronic control system, enabling the battery module to provide power to the electric vehicle. Temperature sensors or smoke sensors, or other detection devices, can be installed on the isolation component 7 to detect abnormal states of the battery packs 8.

[0065] Figure 3 and Figure 4 This is a schematic diagram of the structure of the isolation component 7 in the first embodiment. Figure 5 This is a schematic diagram of the structure of the isolation component 7 in the second embodiment. Figure 6 yes Figure 5 Enlarged diagram of point A in the middle. Figure 6 and Figure 8 The top of the first reinforcing plate 31 is provided with a cross-sectional line. Figure 7 This is a partial structural schematic diagram of the adapter component in this embodiment. Figure 8 This is a partial exploded view of the adapter component in this embodiment. Figure 7 and Figure 8 The partial structure of the first embodiment is shown in the figure.

[0066] In some implementations, such as Figures 3-6 As shown, the isolation component 7 in this embodiment includes a plate 1 and a reinforcing part 2. The reinforcing part 2 protrudes from one side of the plate 1, thereby improving the structural strength of the plate 1. Multiple pressure relief windows 11 are provided on the plate 1, and the multiple pressure relief windows 11 are arranged at intervals and penetrate the plate 1. When the isolation component 7 is placed on top of the battery pack 8, the isolation component 7 can separate the busbar 6 from the battery pack 8. Optionally, the isolation component 7 can be made of an insulating material, such as plastic or rubber.

[0067] Further reference Figures 7-8 As shown, the reinforcing part 2 includes multiple pairs of first baffles 21 corresponding to the multiple pressure relief windows 11. The first baffles 21 protrude from the side of the plate 1 away from the battery pack 8. The first baffles 21 have a stop surface 211, which extends along the arrangement direction of the multiple pressure relief windows 11.

[0068] Specifically, the plate 1 is roughly rectangular, and the first retaining wall 21 extends along the length of the rectangular plate and is spaced apart. This improves the structural strength of the rectangular plate along its length, especially when there are many battery packs 8, resulting in a long rectangular plate, thus increasing the rigidity of the rectangular plate in this direction. When the isolation component 7, together with the busbar 6 and the cover plate 5, forms a transition assembly, it reduces the bending of the transition assembly, ensuring a stable connection between the busbar 6 and each tab 82.

[0069] Meanwhile, the two stop surfaces 211 of each pair of first baffles 21 are opposite to each other and located on both sides of the corresponding pressure relief window 11. In this embodiment, the stop surfaces 211 facing both sides of the pressure relief window 11 can prevent the manifold 6 from moving above the pressure relief window 11, thus avoiding damage to the manifold 6 caused by high-temperature gas leaking from the pressure relief window 11 in abnormal conditions. In addition, it can also prevent the manifold 6 from obstructing the pressure relief window 11.

[0070] In summary, in this embodiment, the isolation component 7 has pressure relief windows 11 on the plate 1, a reinforcing part 2 protruding from one side of the plate 1, and multiple pairs of first baffles 21 corresponding to multiple pressure relief windows 11, with the extension direction of the stop surface 211 consistent with the arrangement direction of the multiple pairs of first baffles 21. Thus, by utilizing the multiple first baffles 21 spaced apart, the structural strength of the plate 1 in the arrangement direction of the multiple pressure relief windows 11 can be improved, preventing the isolation component 7 from easily bending. At the same time, the space occupied by the reinforcing part 2 on the plate 1 is reduced, making the overall shape of the isolation component 7 more flattened. On the other hand, the sides of the stop surface 211 facing the pressure relief windows 11 also prevent the confluence part 6 from moving above the pressure relief windows 11, preventing the confluence part 6 from blocking the pressure relief windows 11 and preventing damage to the confluence part 6 from high-temperature leaked gas.

[0071] In some implementations, such as Figures 3-5 As shown, the first retaining wall 21 protrudes from the edge of the pressure relief window 11. Further referencing... Figures 6-8 As shown, the reinforcing part 2 also includes a first reinforcing plate 31, which is parallel to and spaced apart from the plate body 1 and offset from the central area of ​​the pressure relief window 11. The first retaining wall 21 extends from the plate body 1 to the first reinforcing plate 31.

[0072] Specifically, in this embodiment, the reinforcing part 2 and the plate 1 can be manufactured using vacuum forming. The first retaining wall 21 is perpendicular to both the first reinforcing plate 31 and the plate 1. This improves the processing efficiency of the isolation component 7 and makes the wall thickness of the reinforcing part 2 thinner. That is, the reinforcing part 2 in this embodiment is a thin-walled structure, thereby reducing the weight of the isolation component 7, but also reducing the mechanical strength of the first retaining wall 21 to some extent. For this reason, this embodiment also provides a first reinforcing plate 31 on top of the first reinforcing plate 31, which, like the first retaining wall 21, is a thin-walled structure. Thus, the first reinforcing plate 31 is used to improve the stability of the shape of the first retaining wall 21, preventing deformation of the first retaining wall 21 when the plate 1 is subjected to bending stress.

[0073] In some implementations, such as Figures 5-8 As shown, the first retaining wall 21 includes a second reinforcing plate 32 and a third reinforcing plate 33. One surface of the second reinforcing plate 32 forms the aforementioned stop surface 211. One side edge of the third reinforcing plate 33 is connected to the second reinforcing plate 32, and the other side edge extends toward the second reinforcing plate 32 in a direction away from the stop surface 211. The edge of the first reinforcing plate 31 is simultaneously connected to at least a portion of the third reinforcing plate 33 and at least a portion of the second reinforcing plate 32.

[0074] In this embodiment, the second reinforcing plate 32 and the third reinforcing plate 33 are arranged horizontally around a region, so that when the first reinforcing plate 31 is connected to the second reinforcing plate 32 and the third reinforcing plate 33, the first reinforcing plate 31 can extend in the horizontal direction. Therefore, the first reinforcing plate 31, the second reinforcing plate 32, and the third reinforcing plate 33 can improve the strength of the reinforcing part 2 itself, further improving the rigidity of the plate body 1.

[0075] In some implementations, such as Figure 8 As shown, the first baffle 21 includes two third reinforcing plates 33, and a second reinforcing plate 32 is located between the two third reinforcing plates 33. The two third reinforcing plates 33, corresponding to the same pressure relief window 11 and respectively corresponding to the two first baffles 21, are spaced apart and form pressure relief ports 12 on opposite sides, with the pressure relief ports 12 facing the side of the pressure relief window 11. That is, in this embodiment, two pressure relief ports 12 are formed on opposite sides of the two first baffles 21. Therefore, the gas released by the explosion-proof valve 81 can leak not only from the pressure relief window 11 to the top of the isolation component 7, but also through the pressure relief ports 12 to the side of the pressure relief window 11. This increases the leakage rate of high-pressure gas and prevents excessive pressure inside the battery pack 8.

[0076] In some implementations, such as Figure 6As shown, the first retaining wall 21 includes two third reinforcing plates 33, with a second reinforcing plate 32 located between the two third reinforcing plates 33. The reinforcing part 2 also includes a plurality of fourth reinforcing plates 34 protruding from the edge of the pressure relief window 11. The two third reinforcing plates 33 corresponding to the same pressure relief window 11 and respectively corresponding to the two first retaining walls 21 are connected to the two sides of the fourth reinforcing plates 34. The edge of the first reinforcing plate 31 is simultaneously connected to the second reinforcing plate 32, the third reinforcing plate 33, and the fourth reinforcing plate 34.

[0077] Specifically, four third reinforcing plates 33, two second reinforcing plates 32, and two fourth reinforcing plates 34 are connected to form a enclosure structure. The first reinforcing plate 31 extends from the top of the enclosure structure toward the center and forms a clearance hole. The clearance hole is elongated and corresponds to the center of the pressure relief window 11. This maximizes the mechanical strength of the reinforcing part 2. When high-temperature gas flows through the reinforcing part 2, the reinforcing part 2 can still maintain sufficient rigidity, further reducing the bending deformation of the plate 1.

[0078] In some implementations, such as Figures 6-8 As shown, the plate 1 has multiple tab holes 13, which penetrate the plate 1. The isolation component 7 also includes multiple second baffles 22, which protrude from the plate 1 and are located on both sides of the multiple pressure relief windows 11. The second baffles 22 extend and curve around the tab holes 13, and the second baffles 22 and the plate 1 form a confluence channel 14. The opposite sides of the two ends of the second baffles 22 form clearance openings 15 that communicate with the confluence channel 14.

[0079] Further reference Figure 2 As shown, in this embodiment, the tab hole 13 is used to avoid the tab 82, so that the tab 82 can extend from the tab hole 13 into the busbar groove 14 and thus be electrically connected to the busbar 62.

[0080] In some implementations, such as Figures 7-8 As shown, the isolation component 7 also includes a plurality of positioning posts 41, which protrude from the plate 1 and are located within the busbar groove 14. Each busbar groove 14 has two positioning posts 41, which can cooperate with the positioning holes 621 of the busbar 62 to position the busbar 62.

[0081] In some implementations, such as Figures 7-8 As shown, the isolation component 7 also includes a plurality of limiting blocks 42, which protrude from the side of the second baffle 22 facing the manifold 14, and the limiting blocks 42 are spaced apart from the plate 1.

[0082] Specifically, the busbar 62 has a certain amount of elastic deformation. When the busbar 62 is installed into the busbar groove 14, one side of the busbar 62 can be inserted into the bottom of a limiting block 42 first, and then the busbar 62 can be bent so that the other edge of the busbar 62 is inserted into the bottom of the limiting block 42.

[0083] Preferably, such as Figure 7 As shown, the top of the limiting block 42 is provided with a guide surface, and the side of the guide surface away from the second retaining wall 22 is inclined towards the bottom of the manifold groove 14. Thus, the operator can press the manifold 62 into the manifold groove 14, with the edge of the manifold 62 resting on the guide surface, causing the manifold 62 to bend, thereby reducing the assembly difficulty of the manifold 62.

[0084] In an alternative implementation, the isolation component 7 in the above embodiments can be applied to the adapter assembly. For example... Figures 1-8 As shown, the adapter assembly includes a cover plate 5, an isolation component 7, and a busbar 6. The isolation component 7 includes a plate 1 and a reinforcing component 2. The plate 1 has multiple pressure relief windows 11, which are spaced apart and penetrate the plate 1. The reinforcing component 2 protrudes from the plate 1 and includes multiple pairs of first baffles 21 corresponding to the multiple pressure relief windows 11. Each first baffle 21 has a stop surface 211, which extends along the arrangement direction of the multiple pressure relief windows 11. The two stop surfaces 211 of each pair of first baffles 21 are opposite to each other and located on both sides of the corresponding pressure relief window 11. The busbar 6 is disposed on the isolation component 7 and includes two connecting lines 61 and multiple busbars 62 electrically connected to the connecting lines 61. The two connecting lines 61 extend along the arrangement direction of the multiple pressure relief windows 11 and are located on both sides of the multiple pairs of first baffles 21. The cover plate 5 covers the side of the isolation component 7 where the busbar 6 is disposed.

[0085] In summary, the adapter assembly in this embodiment has a pressure relief window 11 on the plate 1, a reinforcing part 2 protruding from one side of the plate 1, and multiple pairs of first baffles 21 corresponding to multiple pressure relief windows 11, with the extension direction of the stop surface 211 consistent with the arrangement direction of the multiple pairs of first baffles 21. Therefore, by using multiple spaced first baffles 21, the structural strength of the plate 1 in the arrangement direction of the multiple pressure relief windows 11 can be improved, preventing the isolation component 7 from easily bending. At the same time, the space occupied by the reinforcing part 2 on the plate 1 is reduced, making the overall shape of the isolation component 7 more flattened. On the other hand, the sides of the stop surface 211 facing the pressure relief window 11 also prevent the manifold 6 from moving above the pressure relief window 11, preventing the manifold 6 from blocking the pressure relief window 11 and preventing damage to the manifold 6 from high-temperature leaked gas.

[0086] Optionally, such as Figure 2As shown, the cover plate 5 includes multiple pressure relief zones 51 corresponding to the aforementioned multiple clearance holes. When the battery pack 8 is operating normally, the pressure relief zones 51 cover the clearance holes. When the explosion-proof valve 81 releases high-pressure gas through the clearance holes, the pressure relief zones 51 rupture, allowing the gas to be released to the outside of the battery module through the cover plate 5.

[0087] In some implementations, such as Figures 1-8 As shown, the plate 1 has multiple tab holes 13, which penetrate the plate 1. The isolation component 7 also includes multiple second baffles 22, which protrude from the plate 1 and are located on both sides of the multiple pressure relief windows 11. The second baffles 22 extend and curve around the tab holes 13, and the second baffles 22 and the plate 1 form a manifold groove 14. The opposite sides of the two ends of the second baffles 22 form clearance openings 15 that communicate with the manifold groove 14. The manifold 6 also includes multiple connectors 63 corresponding to the multiple manifolds 62. The multiple manifolds 62 are respectively corresponding to the multiple manifold grooves 14, and one end of the connector 63 is connected to the corresponding manifold 62, and the other end is connected to the connecting line 61 through the clearance opening 15.

[0088] Optionally, the busbar 62 in this embodiment can be a copper busbar, copper bar, aluminum busbar, or aluminum bar. The connecting wire 61 and the connector 63 can be a PCB board, FPC (flexible printed circuit board), or FFC (flexible flat cable). The clearance opening 15 in this embodiment is used to allow passage for the connector 63. In addition, the stop surface 211 can prevent the connecting wire 61 from moving above the pressure relief window 11.

[0089] Preferably, such as Figure 3 As shown, two wire grooves 16 are provided on the plate 1. The two wire grooves 16 are located on both sides of multiple pressure relief windows 11, and the connecting wires 61 can be set in the wire grooves 16.

[0090] In some implementations, such as Figures 7-8 As shown, the isolation component 7 also includes multiple positioning posts 41 and multiple limiting blocks 42. The positioning posts 41 protrude from the plate 1 and are located within the busbar groove 14. The limiting blocks 42 protrude from the side of the second retaining wall 22 facing the busbar groove 14, and are spaced apart from the plate 1. The busbar 62 has a positioning hole 621, is disposed in the busbar groove 14, and the positioning posts 41 pass through the positioning hole 621, with the edge of the busbar 62 engaged with the bottom of the limiting blocks 42. Thus, the positioning posts 41 and limiting blocks 42 can be used to limit the busbar 62, preventing the tabs 82 from lifting the busbar 62 out of the busbar groove 14.

[0091] The adapter component in the above embodiments can be applied to a battery module. In some embodiments, such as Figures 1-8As shown, the battery module includes multiple battery packs 8, and each battery pack 8 includes an explosion-proof valve 81 and a tab 82. The adapter assembly is fixedly connected to the multiple battery packs 8, and the multiple explosion-proof valves 81 are respectively provided with multiple pressure relief windows 11, and the tabs 82 abut against the busbar 62.

[0092] Specifically, such as Figure 2 As shown, the multiple busbars 62 include multiple first busbars ( Figure 2 Only one first battery pack 8 is shown, along with two second first battery packs. The first first battery pack 8 is simultaneously connected to the two tabs 82 of two adjacent battery packs 8, with the two tabs 82 having opposite polarities (one positive and the other negative). That is, in the arrangement direction of the multiple battery packs 8, the polarities of the multiple battery packs 8 are staggered. The two second first battery packs are respectively connected to the two tabs 82 of two battery packs 8 located at both ends, and the polarities of the two tabs 82 are also different. Thus, the multiple battery packs 8 are connected in series through the adapter assembly.

[0093] In summary, in this embodiment, the battery module has a pressure relief window 11 on the plate 1, a reinforcing part 2 protruding from one side of the plate 1, and multiple pairs of first baffles 21 corresponding to multiple pressure relief windows 11, with the extension direction of the stop surface 211 consistent with the arrangement direction of the multiple pairs of first baffles 21. Therefore, by using multiple spaced first baffles 21, the structural strength of the plate 1 in the arrangement direction of the multiple pressure relief windows 11 can be improved, preventing the isolation component 7 from easily bending. At the same time, the space occupied by the reinforcing part 2 on the plate 1 is reduced, making the overall shape of the isolation component 7 more flattened. On the other hand, the sides of the stop surface 211 facing the pressure relief window 11 also prevent the manifold 6 from moving above the pressure relief window 11, preventing the manifold 6 from blocking the pressure relief window 11 and preventing damage to the manifold 6 from high-temperature leaked gas.
