Description

Technical Field

[0001] This application relates to the field of new energy battery technology, and more specifically, to an integrated busbar and battery module. Background Technology

[0002] With the rapid development of new energy vehicle technology, battery modules, as one of the core components, have a significant impact on vehicle performance and production costs due to their design and integration efficiency. In traditional battery modules, the signal transmission plug is usually not fixed to the support, causing the plug to be unstable and prone to swinging when the CCS (Cell Connection System) receives the module. This design not only increases the workload of manual fixing but may also lead to interference with mechanical equipment or the housing during module placement, affecting production efficiency and product quality.

[0003] For example, in the assembly process of traditional battery modules, because the signal transmission plug is not fixed to the support body, the plug can only be installed and fixed after the module is placed in the box. This increases the complexity of the production steps and the time cost. In addition, the unstable state of the plug may also cause it to collide with other components during transportation and installation, thereby increasing the risk of damage. Utility Model Content

[0004] In view of this, the purpose of this application is to provide an integrated busbar to improve the problems existing in the prior art: In traditional battery modules, the signal transmission plug is not fixed to the support, which causes the plug to be in an unstable state when the CCS is received, and it is easy to swing, which increases the workload of manual fixing. It may also cause interference with mechanical equipment or the box during the module is put into the box, affecting production efficiency and product quality.

[0005] The integrated busbar includes: a flexible circuit board, a signal transmission plug, and a support member; the support member includes a support member body, a connecting section, and an extension section; the connecting section connects the support member body and the extension section; wherein, the connecting section has a mechanical strength weaker than the support member body and the extension section; the flexible circuit board is disposed on the support member body, and the signal transmission plug is disposed on the extension section; the flexible circuit board and the signal transmission plug are connected by a signal line.

[0006] In the above implementation process, during the production of the battery module, when the integrated busbar arrives, the signal transmission plug is fixed to the support, meaning the signal transmission plug is in a stable state. The flexible circuit board is connected to the signal transmission plug via a signal line. Since the signal transmission plug is already fixed to the extension of the support when it arrives, and the positional relationship between the two is stable, the risk of the plug swinging or loosening is reduced.

[0007] Optionally, the extension includes a fixing portion; the fixing portion is located on a plane of the extension near the signal transmission plug and has a size that matches the size of the signal transmission plug; wherein the fixing portion is configured to fix the signal transmission plug.

[0008] In the above implementation, the fixing part is located on the plane of the extension section near the signal transmission plug, and its size matches the size of the signal transmission plug. This ensures that the signal transmission plug can be securely fixed to the extension section, preventing loosening or displacement of the plug during transportation, assembly, and use, thereby improving the reliability and stability of the connection.

[0009] Optionally, the connecting segment includes a breakable area; the extension direction of the breakable area is consistent with the extension direction of the edge on the support body that connects to the connecting segment.

[0010] In the above implementation process, the extension direction of the easily breakable area is consistent with the extension direction of the edge on the support body that connects to the connecting section. That is, when the connecting section is broken, the direction of structural fracture or weakness after being subjected to force matches the direction of the weak point in the structure, making the breaking process more precise and controllable. Operators or automated equipment only need to apply appropriate force in a predetermined direction to easily break the connecting section, avoiding incomplete fracture or residual parts caused by mismatched breaking directions, thus improving work efficiency and operational convenience.

[0011] Optionally, the easily broken region includes multiple high-stress regions and multiple low-stress regions; the multiple high-stress regions and multiple low-stress regions are arranged alternately along the extension direction of the easily broken region.

[0012] In the above process, weak stress areas will fracture preferentially, while strong stress areas provide support and guidance, ensuring that the breakage follows a predetermined path, avoiding irregular fractures or residual parts, simplifying the breaking operation, and reducing the defect rate caused by improper breaking. On the production line, workers or automated equipment can quickly and accurately complete the breaking of the connecting section, improving production efficiency. At the same time, a unified breaking method and path also helps to achieve automated production, further improving production quality and consistency.

[0013] Optionally, the easily broken area includes a mesh structure, an array of holes, or a continuous groove.

[0014] In the above implementation process, the mesh structure guides the crack to propagate in a specific direction through its regular geometry; the array of holes reduces damage caused by stress concentration by forming uniformly distributed stress relief points in the material; and the continuous grooves also enable the crack to propagate uniformly along the path of the grooves when the connecting section is broken.

[0015] Optionally, the easily broken area is a mesh structure; the mesh structure includes at least two connecting ribs; one end of the connecting rib is connected to the extension section, and the other end of the connecting rib is connected to the support body.

[0016] In the above implementation process, the connecting ribs in the mesh structure form regular geometric paths, allowing cracks to propagate evenly along these paths when the connecting segment breaks. In the unbroken state, the connecting ribs of the mesh structure make the entire connecting segment more stable.

[0017] Optionally, at least two of the connecting ribs include at least one common node; wherein the common node is a stress concentration point; wherein, when at least two of the connecting ribs include at least two common nodes, the at least two common nodes are arranged on the same straight line.

[0018] In the above implementation process, the common node serves as a stress concentration point, and multiple common nodes are arranged on the same straight line, which enables the connection segment to be neatly broken on the predetermined straight line, avoiding irregular fractures or residual parts. This allows workers or automated equipment on the production line to quickly and accurately complete the breaking of the connection segment, improving production efficiency.

[0019] Optionally, the easily breakable region includes guide grooves disposed on both sides thereof; the extending direction of the guide grooves is consistent with the extending direction of the easily breakable region.

[0020] In the above implementation process, effective guidance of the breaking direction is achieved without increasing the additional space. When performing the breaking operation, the operator does not need to make additional judgments about the breaking direction; they only need to operate along the obvious path of the guide groove, simplifying the operation steps and reducing the difficulty of operation.

[0021] This application embodiment also provides a battery module, the battery module including an integrated busbar; the integrated busbar includes: a flexible circuit board, a signal transmission plug, and a support member; the support member includes a support member body and an extension section; the flexible circuit board is disposed on the support member body, and the signal transmission plug is disposed on the extension section; the flexible circuit board and the signal transmission plug are connected by a signal line; wherein, the support member body includes a first fracture portion, and the extension section includes a second fracture portion, the first fracture portion and the second fracture portion having a mechanical strength weaker than the support member body and the connecting section.

[0022] In the above implementation process, the support body of the battery module integrated busbar includes a first fracture portion, and the extension section includes a second fracture portion, both of which have relatively weak mechanical strength. When it is necessary to detach the signal transmission plug from the support for subsequent connection, the weak mechanical strength of the first and second fracture portions allows them to be easily broken. After breaking, the signal transmission plug separates from the extension section, facilitating its accurate installation into the designated position on the battery module, improving the precision and reliability of the connection. Simultaneously, this design simplifies the plug separation and installation steps, allowing for rapid breaking and connection operations on the production line, reducing assembly time and improving overall production efficiency. Furthermore, the broken edges are neater, reducing the interference of burrs or irregular edges on maintenance and repair work, making component replacement and repair more convenient when needed, thus improving work efficiency.

[0023] Optionally, the battery module further includes: an end plate; the signal transmission plug is inserted into the end plate.

[0024] In the above implementation process, the endplate provides a precise positioning and insertion interface for the signal transmission plug. On the production line, the endplate design simplifies and speeds up the installation process of the signal transmission plug. Workers or automated equipment simply align the broken plug with the interface on the endplate and insert it, reducing assembly time and operational complexity, and improving production efficiency.

[0035] 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 the embodiments of this application.

[0036] Optionally, please see Figure 1 , Figure 1 This is a schematic diagram of an integrated busbar provided in an embodiment of this application.

[0037] Depend on Figure 1 As can be seen, the integrated busbar includes: a flexible circuit board 300, a signal transmission plug 200, and a support member; the support member includes a support member body 110, a connecting section 120, and an extension section 130; the connecting section 120 connects the support member body 110 and the extension section 130; wherein, the connecting section 120 has a mechanical strength weaker than the support member body 110 and the extension section 130; the flexible circuit board 300 is disposed on the support member body 110, and the signal transmission plug 200 is disposed on the extension section 130; the flexible circuit board 300 and the signal transmission plug 200 are connected by a signal line.

[0038] In the above implementation process, by integrating the flexible circuit board 300, signal transmission plug 200, and support component together, the number of parts is reduced, thereby improving the integration and space utilization of the battery module. Simultaneously, the support component body 110, connecting section 120, and extension section 130 give the entire support component good mechanical properties and reliability, effectively protecting the internal flexible circuit board 300 and signal transmission plug 200. Because the connecting section 120 has relatively weak mechanical strength, it will preferentially deform or break under external impact or vibration, thus protecting the mechanically stronger support component body 110 and extension section 130, as well as key components such as the flexible circuit board 300 and signal transmission plug 200 mounted on them, improving the safety and reliability of the entire battery module. Furthermore, the weaker connecting section 120 can be easily broken, allowing the extension section 130 to separate from the support component body 110, facilitating corresponding operations and improving work efficiency and maintenance convenience.

[0039] In one embodiment of this application, please refer to Figure 1 See Figure 2 , Figure 2 This is a schematic diagram of an integrated busbar provided in an embodiment of this application.

[0040] Optionally, the extension 130 includes a fixing part 131; the fixing part 131 is located on a plane of the extension 130 near the signal transmission plug 200 and has a size that matches the size of the signal transmission plug 200; wherein the fixing part 131 is configured to fix the signal transmission plug 200.

[0041] In the above implementation process, the fixing part 131 is matched in size with the signal transmission plug 200, preventing the plug from loosening or shifting during transportation, assembly, and use, thereby improving the reliability and stability of the connection. The fixing part 131 not only serves a fixing function but also provides a certain degree of protection for the signal transmission plug 200. When the battery module is subjected to external impact or vibration, the fixing part 131 can effectively buffer and disperse the force, reducing the risk of plug damage. On the production line, workers or automated equipment can quickly align the plug with the fixing part 131 and fix it, reducing assembly time and improving overall production efficiency.

[0042] Optionally, please refer to Figure 3 , Figure 3 This is a schematic diagram of a connection segment provided in an embodiment of this application.

[0043] Optionally, the connecting segment 120 includes a breakable area; the direction of extension of the breakable area is consistent with the direction of extension of the edge on the support body 110 that connects to the connecting segment 120.

[0044] In the above implementation process, combined with Figure 3 As can be seen, the extension direction of the easily breakable area is consistent with the extension direction of the edge of the support body 110. This ensures that when the connecting section 120 is broken, the direction of the force matches the direction of the weak point of the structure. That is, the connecting section 120 can be neatly broken at the predetermined position, avoiding irregular fractures or residual parts. Similarly, it also avoids stress concentration, thereby reducing the risk of impact and damage to surrounding components during the breaking process and protecting key components such as the flexible circuit board 300 and the signal transmission plug 200. On the production line, workers or automated equipment can quickly and accurately complete the breaking of the connecting section 120, improving production efficiency.

[0045] Optionally, the easily broken region includes multiple high-stress regions and multiple low-stress regions; the multiple high-stress regions and multiple low-stress regions are arranged alternately along the extension direction of the easily broken region.

[0046] In the above implementation process, in the unbroken state, the alternating arrangement of high-stress and low-stress regions effectively supports the flexible circuit board 300 and the signal transmission plug 200. Simultaneously, under abnormal external force, deformation or fracture preferentially occurs in the low-stress regions, protecting other critical components from damage. The alternating arrangement of multiple high-stress and low-stress regions ensures that when the connecting segment 120 is broken, the crack can propagate along a predetermined path. The low-stress regions fracture preferentially, while the high-stress regions guide the crack propagation direction, allowing the connecting segment 120 to break cleanly at a predetermined location, avoiding irregular fractures or residual parts.

[0047] Specifically, please refer to Figure 4 , Figure 5 , Figure 6 as well as Figure 7 , Figure 4 This is a schematic diagram of the connecting segment mesh structure provided in an embodiment of this application; Figure 5 This is a schematic diagram of the connection segment hole array provided in an embodiment of this application; Figure 6 This is a schematic diagram of a continuous groove in the connecting section provided in an embodiment of this application.

[0048] Alternatively, the easily broken areas may include a mesh structure, an array of holes, or a continuous groove.

[0049] In the above implementation process, combined with Figure 4 It can be seen that the mesh structure increases the flexibility of the material through its regular geometric shape, guides crack propagation, optimizes stress distribution, and reduces the risk of damage to the material during use; combined with Figure 5 It can be seen that the perforated array, through its uniformly distributed perforations, ensures a uniform stress distribution; combined with Figure 6As can be seen, continuous grooves provide a clear path for crack propagation, guiding the crack to extend in a predetermined direction, avoiding stress concentration, and improving structural stability. All three methods can facilitate automated production, simplify breakage operations, and reduce the defect rate.

[0050] Next, please combine Figure 3 See Figure 7 , Figure 7 This is a schematic diagram of another connection segment provided in an embodiment of this application.

[0051] Optionally, the easily broken area is a mesh structure; the mesh structure includes at least two connecting ribs; one end of the connecting rib is connected to the extension section 130, and the other end of the connecting rib is connected to the support body 110.

[0052] In the above implementation process, the easily breakable area adopts a mesh structure design. This mesh structure consists of at least two connecting ribs, with one end of each rib connected to the extension section 130 and the other end connected to the support body 110. The connecting ribs of the mesh structure form regular geometric paths, allowing cracks to propagate evenly along these paths when the connecting section 120 is broken, ensuring the precision and controllability of the breaking process and avoiding irregular fractures or residual parts. Furthermore, in the unbroken state, it effectively supports the flexible circuit board 300 and the signal transmission plug 200, maintaining structural stability. When subjected to abnormal external forces, deformation or fracture occurs preferentially at the weakest points of the connecting ribs, protecting other critical components from damage. On the production line, this simplifies the breaking operation, reduces the defect rate caused by improper breaking, and improves production efficiency and product quality. Simultaneously, the standardized breaking method and path also facilitates automated production, further improving production quality and consistency.

[0053] Optionally, at least two connecting bars include at least one common node; wherein the common node is a stress concentration point; wherein, in the case where at least two connecting bars include at least two common nodes, the at least two common nodes are arranged on the same straight line.

[0054] In the above implementation process, the easily breakable area adopts a mesh structure design, in which at least two connecting ribs include at least one common node, and when at least two connecting ribs include at least two common nodes, these common nodes are arranged in a straight line. The common nodes act as stress concentration points, and the arrangement of multiple common nodes in a straight line allows the connecting segment 120 to be neatly broken along a predetermined straight line, avoiding irregular fractures or residual parts, and improving the reliability and accuracy of the operation. The stress concentration and guiding effect reduces the stress burden on other areas, preventing stress concentration in unexpected areas, thereby reducing the risk of material damage and protecting key components such as the flexible circuit board 300 and the signal transmission plug 200. On the production line, workers or automated equipment can quickly and accurately complete the breaking of the connecting segment 120, improving production efficiency.

[0055] In one embodiment of this application, such as Figure 3 As shown, the connecting ribs are two parallel straight line segments connecting the extension segment 130 and the support body 110. Since the mechanical strength of the easily broken area of ​​the connecting segment 120 differs from that of the extension segment 130 and the support body 110, and the mechanical strength of the easily broken area of ​​the connecting segment 120 is weaker than that of the extension segment 130 and the support body 110, when it is necessary to separate the extension segment 130 and the support body 110, a certain force (here, two parallel straight line segments) is applied to the connecting ribs. After being subjected to force, the direction of structural fracture or weakness matches the direction of the weak point in the structure, thus separating the two parts. Simultaneously, this allows workers or automated equipment on the production line to quickly and accurately complete the breaking of the connecting segment, improving production efficiency.

[0056] In one embodiment of this application, such as Figure 4 As shown, the easily breakable area of ​​the connecting segment 120 is formed by a diamond pattern of intersecting straight segments of multiple connecting ribs, arranged along the extension direction of the edge on the support body 110 that connects to the connecting segment 120. Two connecting ribs share a common node, and at least two common nodes are arranged on the same straight line. When it is necessary to separate the extension segment 130 and the support body 110, a certain force is applied to the connecting ribs (here, a mesh structure formed by intersecting straight segments of multiple connecting ribs). Because the common node acts as a stress concentration point, and multiple common nodes are also arranged on the same straight line, the connecting segment 120 can be neatly broken on a predetermined straight line (the line where multiple common nodes are located) after being subjected to force, avoiding irregular fractures or residual parts. Simultaneously, this allows workers or automated equipment on the production line to quickly and accurately complete the breaking of the connecting segment, improving production efficiency.

[0057] In one embodiment of this application, such as Figure 5 As shown, compared to Figure 4 The fragile area shown is... Figure 5 The easily fractured area arranged in a perforated array can have greater mechanical strength under the same conditions. These "same conditions" can mean that the number of openings on the same straight line is the same as the number of rhombuses on the same straight line in the mesh structure, or that the size of the openings is approximately the same as the size of the rhombuses. It's easy to understand that, under these conditions, if the extension section 130 is not yet broken, the risk of damage to the integrated busbar during transportation, in the event of a potential collision with other components, will be relatively reduced. This ensures overall mechanical strength while also allowing for easy breakage of the connecting section 120 by applying appropriate force along a predetermined direction, thus separating the extension section 130 from the support body 110.

[0058] In one embodiment of this application, such as Figure 6 As shown, the easily breakable area in the connecting section 120 is a continuous groove. The groove has weaker mechanical strength than the surrounding area, allowing it to break along a preset path. Compared to the previous two methods, this embodiment can achieve better breakage along a specific path.

[0059] Optionally, the number, length, spacing, and shape of the connecting ribs can be freely matched according to requirements. It is known that straight connecting ribs are selected to connect the extension section 130 and the support body 110 in parallel, and can be distributed at equal intervals or asymmetrically. The straight segments of the connecting ribs or the mesh pattern, hole array, or continuous groove arrangement formed by the straight segments of the connecting ribs are all set between the extension section 130 and the support body 110, and arranged along the extension direction of the edge on the support body 110 that connects to the connecting section 120. The shape and size of the mesh pattern and the shape and size of the holes can also be adjusted according to requirements. The continuous grooves can be set on one side or both sides, can run through the entire connecting section 120, or can be arranged in the form of dotted lines.

[0060] Optionally, the easily breakable area includes guide grooves disposed on both sides thereon; the extension direction of the guide grooves is consistent with the extension direction of the easily breakable area.

[0061] In the above implementation process, guide grooves are provided on both sides of the easily breakable area, and the extension direction of the guide grooves is consistent with the extension direction of the easily breakable area. The guide grooves provide a clear path for crack propagation, enabling the connecting segment 120 to break neatly at a predetermined position, avoiding irregular fractures or residual parts, simplifying the breaking operation, and reducing the defect rate caused by improper breaking. On the production line, workers or automated equipment can quickly and accurately complete the breaking of the connecting segment 120, improving production efficiency.

[0062] In one embodiment of this application, using Figure 4For example, at both ends of the extension direction of the mesh structure, the "V" shape formed by two connecting ribs has a clear directional characteristic, pointing towards the predetermined fracture path of the mesh structure; similarly, with Figure 5 For example, in the case of a hole array, two non-completely closed holes can be set at both ends of the connecting section along the edge of the support body as guide grooves to achieve the purpose of pointing to its fracture path.

[0063] Optionally, please refer to Figure 8 , Figure 8 This is a schematic diagram of a battery module provided in an embodiment of this application.

[0064] This application embodiment also provides a battery module, which includes an integrated busbar; the integrated busbar includes a flexible circuit board 300, a signal transmission plug 200, and a support member; the support member includes a support member body 110 and an extension section 130; the flexible circuit board 300 is disposed on the support member body 110, and the signal transmission plug 200 is disposed on the extension section 130; the flexible circuit board 300 and the signal transmission plug 200 are connected by a signal line; wherein, the support member body 110 includes a first fracture portion 121, and the extension section 130 includes a second fracture portion 122, the first fracture portion 121 and the second fracture portion 122 having a mechanical strength weaker than that of the support member body 110 and the connecting section 120.

[0065] In the above implementation process, the first fracture portion 121 and the second fracture portion 122 are obtained through fracture. Because their mechanical strength is relatively weak in the connected state, the weaker fracture portion can be easily broken off, allowing the extension section 130 to separate from the support body 110. This facilitates the corresponding operations, improving work efficiency and maintenance convenience. On the production line, this easily breakable design simplifies the plug separation and installation steps. Workers or automated equipment can quickly complete the breaking and connection operations, reducing assembly time and improving overall production efficiency.

[0066] Optionally, the battery module also includes: an end plate 400; and a signal transmission plug 200 plugged into the end plate 400.

[0067] In the above implementation process, after the signal transmission plug 200 on the extension section 130 is broken off, the plug can be accurately inserted into the corresponding position on the end plate 400. On the production line, workers or automated equipment only need to align the broken plug with the interface on the end plate 400 and insert it, reducing assembly time and operational complexity. By simplifying the assembly process and reducing maintenance time, production efficiency is improved.

[0068] In summary, the purpose of this application is to provide an integrated busbar, which includes: a flexible circuit board 300, a signal transmission plug 200, and a support member; the support member includes a support member body 110, a connecting section 120, and an extension section 130; the connecting section 120 connects the support member body 110 and the extension section 130; wherein, the connecting section 120 has a mechanical strength weaker than the support member body 110 and the extension section 130; the flexible circuit board 300 is disposed on the support member body 110, and the signal transmission plug 200 is disposed on the extension section 130; the flexible circuit board 300 and the signal transmission plug 200 are connected by a signal line. This addresses the problems existing in the prior art: in traditional battery modules, the signal transmission plug is not fixed to the support member, causing the plug to be unstable when the CCS arrives, easily swinging, increasing the workload of manual fixing, and potentially causing interference with mechanical equipment or the casing during module loading, affecting production efficiency and product quality.
