Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle batteries. Specifically, this utility model relates to an FPC single-panel stacked structure. Background Technology

[0002] With the continuous upgrading and iteration of domestic new energy vehicle technology, coupled with the rapid development of the energy storage market, under the same space constraints, the denser the cell arrangement and the more cells there are, the higher the battery energy density, the higher the driving range of new energy vehicles and the higher the energy storage capacity of energy storage products. Traditional wiring harness solutions, due to their large space requirements, have been partially replaced by FPC solutions and have become the mainstream solution for new energy vehicle manufacturing in the current market. However, due to the limitations of wiring space, FPC cannot complete wiring under certain conditions, such as in environments with small wiring space width and high acquisition density, using only a single-sided FPC. On the other hand, double-sided FPCs are expensive and have poor reliability.

[0003] To address the aforementioned issues, patent application number 2021221983624 discloses a new energy battery FPC that does not require soldering nickel sheets, comprising: a reinforcing layer, a first adhesive layer, a first cover film layer, a second adhesive layer, a copper foil layer, a third adhesive layer, a second cover film layer, a fourth adhesive layer, and a gold finger reinforcing support layer arranged sequentially from top to bottom; the copper foil layer is further provided with gold-plated gold fingers and several nickel-plated pads, but this does not solve the aforementioned problems.

[0004] Therefore, in order to improve or solve at least one of the above problems, a high-reliability FPC single-sided stacking structure is provided that is suitable for environments with small wiring space and high acquisition density, can complete wiring, helps reduce costs, and is highly reliable. Utility Model Content

[0005] This utility model is designed to solve the aforementioned problems. Its purpose is to provide an FPC single-sided board stacking structure that is suitable for environments with limited wiring space and high data acquisition density, capable of completing wiring, reducing costs, and offering high reliability. To achieve the above objective, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides an FPC single-sided stacked structure, which includes a bottom FPC and a top FPC disposed on the bottom FPC, with one side of the bottom FPC connected to one side of the top FPC.

[0007] The FPC single-panel stacked structure provided by this utility model may also have the following feature: the top FPC is connected to the battery front-end voltage and temperature acquisition unit.

[0008] The FPC single-panel stacked structure provided by this utility model may also have the following feature: the bottom FPC is connected to the battery back-end voltage and temperature acquisition unit.

[0009] In the FPC single-sided stacked structure provided by this utility model, it can also have the following feature: the copper material on the surface of the top FPC and the bottom FPC is rolled copper.

[0010] The FPC single-sided stacked structure provided by this utility model may also have the following feature: the top FPC and the bottom FPC are wired separately.

[0011] The FPC single-sided stacked structure provided by this utility model may also have the following feature: the top FPC and the bottom FPC are manufactured using a single-sided process.

[0012] The technical advantages of this utility model are as follows: The FPC single-sided stacked structure provided by this utility model includes a bottom FPC and a top FPC disposed on the bottom FPC. One side of the bottom FPC is connected to one side of the top FPC. By assembling the bottom FPC and the top FPC on both sides, the cost is reduced and the manufacturing efficiency is improved on the traditional double-sided FPC substrate. The process risks of traditional double-sided FPC are eliminated. The external dimensions of the FPC single-sided stacked structure can be adjusted according to different product shapes. Both the top and bottom sides can be manufactured separately and cost control can be carried out separately. This makes the FPC single-sided stacked structure provided by this utility model suitable for environments with small wiring space and high acquisition density. It can complete wiring, which helps to reduce costs and has high reliability. Attached Figure Description

[0017] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0019] like Figure 1 and Figure 2 As shown, the FPC single-sided stacked structure provided by this utility model includes a bottom FPC 10 and a top FPC 20 disposed on the bottom FPC 10. One side of the bottom FPC 10 is connected to one side of the top FPC 20.

The process risks of traditional double-sided FPC are eliminated. The external dimensions of the FPC single-sided stacked structure can be adjusted according to different product shapes. Both the top and bottom sides can be manufactured separately and cost control can be carried out separately. This makes the FPC single-sided stacked structure provided by this utility model suitable for environments with small wiring space and high acquisition density. It can complete wiring, which helps to reduce costs and has high reliability.

[0020] The top FPC20 is connected to the battery front-end voltage and temperature acquisition unit, and the bottom FPC10 is connected to the battery rear-end voltage and temperature acquisition unit. This allows the FPC single-panel stacking structure provided by this utility model to meet wiring requirements and be suitable for environments with small wiring space width and high acquisition density.

[0021] The copper material on the surface of the bottom FPC10 and top FPC20 is rolled copper, which has excellent bending resistance. The bottom FPC10 and top FPC20 adopt a separate wiring method with no vias, resulting in small resistance deviation, good insulation withstand voltage, and small difference in overall performance. The bottom FPC10 and top FPC20 are manufactured using a single-sided board process, which facilitates the control of dimensional tolerances.
