Description

Technical Field

[0001] This utility model belongs to the field of integrated busbar support technology, specifically relating to an integrated busbar support and an integrated busbar using the integrated busbar support. Background Technology

[0002] In the field of new energy power and energy storage battery technology, the acquisition of voltage and temperature data of battery modules is a key link to ensure battery safety and performance. For this reason, battery modules are equipped with integrated busbars to detect their data and ensure safe use.

[0003] The integrated busbar mainly consists of a support frame, an FPC mounted on the support frame, and current guides. Connectors are located at the ends of the FPC, and numerous components are mounted on the main structure of the FPC. When the integrated busbar is assembled onto the battery module, the entire integrated busbar is fixed to the battery module's housing; only the connectors and a small portion of the FPC droop without support from the support frame and battery module housing. However, in this drooping state, the edges of the FPC opposite the battery module housing are susceptible to impact or scratches, which can damage the components on the FPC and easily sever the conductors. In practice, the battery module housing is made of metal. To insulate the battery module housing from the PFC, foam needs to be placed between the two, which not only increases cost but also adds to the manufacturing complexity. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an integrated busbar support.

[0005] To achieve the above objectives, this utility model discloses an integrated busbar support, comprising an integrally formed first mounting plate, a second mounting plate, and a third mounting plate, with the second and third mounting plates located on opposite sides of the first mounting plate. The first mounting plate is used to support and fix a flexible printed circuit board. One end of the first mounting plate is provided with a vertically downward-facing insulating partition, one end of which is connected to the first mounting plate, and the contact surface between the two is an arc surface. Both the second and third mounting plates are provided with multiple mounting positions for mounting guide components of the integrated busbar, and each mounting position is provided with a clearance hole.

[0006] Preferably, the insulating partition includes an inclined plate and a straight plate, with both ends of the inclined plate connected to one end of the first mounting plate and one end of the straight plate, respectively. The inclined plate is inclined away from the first mounting plate, and the straight plate is vertically downward.

[0007] Preferably, the contact surface between the inclined plate and the straight plate is an arc surface.

[0008] Preferably, the insulating partition is a one-piece molded structure.

[0009] Preferably, the first mounting plate and the insulating partition are integrally formed.

[0010] Preferably, the insulating partition is bent to a vertical direction by a bending process to form the arc surface.

[0011] Preferably, the material of the integrated busbar support is polycarbonate.

[0012] Preferably, the first mounting plate is provided with a first hot riveting post for positioning the flexible printed circuit board.

[0013] Preferably, the second mounting plate and the third mounting plate are provided with second hot riveting posts for fixing the guide member.

[0014] This utility model also provides an integrated busbar using any of the above-described integrated busbar brackets.

[0015] An integrated busbar includes an integrated busbar support, a flexible printed circuit board disposed on the integrated busbar support, and a plurality of flow guides, wherein the integrated busbar support is any one of the integrated busbar supports described above.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The integrated busbar bracket of this utility model has an insulating partition set vertically downward at one end of the first mounting plate. The insulating partition can separate the battery module housing and the FPC, thereby isolating and protecting the components on the FPC and preventing the battery module from leaking current and damaging the components on the FPC.

[0018] The contact surface between the insulating partition and the first mounting plate is an arc surface. This arc surface can cover the edges of the battery module. When the connector is in a drooping state, the position on the FPC that is opposite to the edge of the battery module shell can be supported by the arc surface, rather than the metal edge. This can greatly reduce the damage to the FPC and its components and improve the service life of the FPC. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] An integrated busbar, see Figures 1-3 It includes an integrated busbar support 1, a flexible printed circuit board 2 disposed on the integrated busbar support 1, and multiple flow guides 3. The flexible printed circuit board 2 is provided with a connector 21. The above structures are existing structures and will not be described in detail here.

[0027] The integrated busbar support 1 includes an integrally formed first mounting plate 11, a second mounting plate 12, and a third mounting plate 13. The first mounting plate 11 is used to support and fix the flexible printed circuit board 2. Specifically, the first mounting plate 11 is provided with a first hot-riveting post 111 for positioning the flexible printed circuit board 2. After the first hot-riveting post 111 positions the flexible printed circuit board 2, it is fixed by a hot-riveting process. The second mounting plate 12 and the third mounting plate 13 are located on both sides of the first mounting plate 11. Both the second mounting plate 12 and the third mounting plate 13 are provided with multiple mounting positions for mounting the flow guide 3 of the integrated busbar. Specifically, the mounting position is a groove structure, and a second hot-riveting post 14 is provided in the groove. After the flow guide 3 is installed in the mounting position, it is positioned by the second hot-riveting post 14 and fixed by a hot-riveting process. Each mounting position 15 is provided with a clearance hole 151 to allow the flow guide 3 to connect with the battery cell.

[0028] In this embodiment, one end of the first mounting plate 11 is provided with a vertically downward-facing insulating partition 16. The insulating partition 16 can separate the battery module housing and the FPC, thereby isolating and protecting the components on the FPC and preventing damage to the components on the FPC due to leakage from the battery module. One end of the insulating partition 16 is connected to the first mounting plate 11, and the contact surface between the two is an arc surface. This arc surface can cover the edge of the battery module. When the connector 21 is in the drooping state, the position on the FPC opposite to the edge of the battery module housing can be supported by the arc surface, rather than the metal edge. This can greatly reduce damage to the FPC and its components and improve the service life of the FPC.

[0029] In this embodiment, the insulating partition 16 includes an inclined plate 161 and a straight plate 162. The two ends of the inclined plate 161 are connected to the first mounting plate 11 and one end of the straight plate 162, respectively. The inclined plate 161 is tilted away from the first mounting plate 11, which ensures the distance between the FPC and the battery module housing, thus isolating and protecting the FPC. The straight plate 162 is vertically downward, which adapts to the shape of the connector 21 in its drooping state, while avoiding the insulating partition 16 being completely tilted, thus avoiding increased occupancy of lateral space.

[0030] In order to further protect the components on the FPC, the contact surface between the inclined plate 161 and the straight plate 162 is an arc surface.

[0031] In this embodiment, the insulating partition 16 is an integrally molded structure, specifically formed by injection molding, which is a mature, simple, and low-cost process.

[0032] In this embodiment, the first mounting plate 11 and the insulating partition 16 are integrally formed structures. This processing technology is mature, simple, and low in cost.

[0033] In order to facilitate processing and mold structure design, the insulating partition 16 is generally set as a straight plate 162 coplanar with the first mounting plate 11. After processing, the insulating partition 16 is bent to the vertical direction by bending process, and at the same time, two arc surfaces are formed.

[0034] In this embodiment, the material of the integrated busbar support 1 is polycarbonate (PC). After molding, the integrated busbar support 1 of this material has a certain degree of flexibility, and its elastic properties are close to those of FPC, which allows FPC to be closer to the insulating partition 16 and provide better protection for the insulating partition 16.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
