Description

Technical Field

[0001] This application relates to the field of battery module technology, and in particular to a connection structure for a battery module FPC. Background Technology

[0002] Currently, battery modules are composed of multiple lithium batteries connected in series and parallel. They are connected in series by connecting tabs placed on the positive and negative terminals of adjacent lithium batteries. Existing battery modules need to be connected to a battery protection module. The current connection method is to connect the FPC of the battery protection module to the connecting tab through the acquisition lines, so that the positive and negative terminals of the battery are electrically connected to the FPC. The disadvantage of this connection method is that multiple acquisition lines need to be fixed with glue or a fixing structure, which results in unstable acquisition line connections, cumbersome connection operations, and messy and unsightly multiple acquisition lines. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a connection structure for a battery module FPC, including a housing for supporting a plurality of batteries, a connecting plate mounted on the top of the housing, an FPC protection plate fixedly mounted on the connecting plate, and a plurality of aluminum sheets embedded in the connecting plate that are connected to the terminals of each of the batteries, the aluminum sheets being connected to the FPC protection plate via connecting pieces.

[0004] Preferably, the connecting plate has a plurality of positioning holes, and a fixing member that mates with the positioning holes is provided on the connecting plate.

[0005] Preferably, the FPC protection plate has connection terminals at both ends, and grooves for avoiding the connection terminals are provided on both sides of the housing.

[0006] Preferably, a support frame is placed inside the base, and a plurality of partitions are provided inside the support frame.

[0007] Preferably, the fastener is a bolt that passes through the positioning hole and is threaded to the top of the housing.

[0008] As can be seen from the above, the following beneficial effects can be obtained by applying the method provided in this application: by setting up a box for carrying batteries, a connecting plate is installed on the top of the box, an FPC protection board is fixedly installed on the connecting plate, and several aluminum sheets are embedded in the connecting plate. The aluminum sheets are connected to the terminals of each battery through the aluminum sheets, and the aluminum sheets are connected to the FPC protection board through the connecting plates, thereby realizing the connection between the battery module and the FPC protection board. This avoids the problem of needing to organize and fix the acquisition lines caused by the connection method of acquisition lines, and improves the stability of the connection between the battery module and the FPC protection board.

[0013] 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 this application.

[0014] Example

[0015] To address the aforementioned technical problems, this embodiment provides a connection structure for a battery module FPC, such as... Figure 1-2 As shown, the device includes a housing 10 for carrying several batteries 20. A connecting plate 30 is installed on the top of the housing 10. An FPC protection plate 40 is fixedly installed on the connecting plate 30. Several aluminum sheets 50 are embedded in the connecting plate 30. The aluminum sheets 50 are connected to the terminals of each battery 20 through the aluminum sheets 50. The aluminum sheets 50 are connected to the FPC protection plate 40 through connecting pieces 51, thereby realizing the connection between the battery module and the FPC protection plate 40. This avoids the use of the existing connection method through the acquisition line, thereby improving the stability of the connection between the battery module and the FPC protection plate 40.

[0016] Specifically, to fix the connecting plate 30 to the housing 10, several positioning holes are provided on the connecting plate 30, and a fixing member 14 that mates with the positioning holes is provided on the housing 10. After the battery 20 is placed inside the housing 10, the connecting plate 30 is fixed to the top of the housing 10 by the fixing member 14. For example, after multiple batteries are placed inside the housing 10, the positive and negative terminals of adjacent batteries 20 are connected in series by a metal sheet. After the connecting plate 30 is fixed to the housing 10, the aluminum sheet 50 embedded in the connecting plate 30 contacts the terminals of the battery 20, and then the aluminum sheet 50 is connected to the contact end of the FPC protection board 40 by a connecting piece 51, thereby completing the electrical connection between the FPC protection board 40 and the battery module. The connection method using the connecting piece 51 replaces the existing connection method using acquisition wires, avoiding the need for tidying and fixing acquisition wires, and resulting in a neat appearance.

[0017] In the above scheme, for example, the fastener 14 is a bolt that passes through the positioning hole. The bolt is threaded to the top of the housing 10, thereby realizing the detachable connection between the connecting plate 30 and the housing 10. The connecting plate 30 serves to fix the battery 20 inside the housing 10. At the same time, the detachable connection between the connecting plate 30 and the housing 10 facilitates the disassembly and maintenance of the battery module.

[0018] Furthermore, connection terminals 41 are formed at both ends of the FPC protection board 40, and grooves 13 are provided on both sides of the housing 10 to prevent the connection terminals 41 from being exposed, so that the connection terminals 41 can be placed in the grooves 13 and extend outward. At the same time, after multiple batteries are connected in series to form a battery module, connection terminals 60 for connecting to external devices extend from both ends of the battery module.

[0019] In the above scheme, in order to fix each battery in place, such as Figure 3 As shown, a support frame 11 is placed inside the base 10, and several partitions 12 are provided inside the support frame 11. The partitions 12 divide the interior of the support frame 11 into multiple accommodating spaces for placing batteries, so that multiple batteries can be neatly placed inside the support frame 11, and the partitions 12 limit the position of each battery to ensure that the battery does not shift during the welding process.

[0020] In summary, the solution proposed in this application sets up a housing for carrying the battery, installs a connecting plate on the top of the housing, fixes an FPC protection board on the connecting plate, and embeds several aluminum sheets on the connecting plate. The aluminum sheets are connected to the terminals of each battery through the aluminum sheets, and the aluminum sheets are connected to the FPC protection board through the connecting plates. This achieves the connection between the battery module and the FPC protection board, avoiding the problem of needing to organize and fix the acquisition lines that would result from using the acquisition line connection method, and improving the stability of the connection between the battery module and the FPC protection board.

[0021] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
