Description

Technical Field

[0001] This utility model relates to the technical field of FFC integrated busbars, specifically to a locking and fixing structure for FFC integrated busbars. Background Technology

[0002] With the rapid development of new energy electric vehicles and energy storage industries, the reliability of the internal electrical connections of the battery pack, which is the core power source, is of paramount importance. Due to its advantages such as high integration and lightweight, FFC (Flexible Flat Cable) integrated busbars have become the mainstream solution for connecting cells in battery packs.

[0003] However, the current mainstream FFC integrated busbar locking and fixing technology uses a structure with "fixing ears" designed on the rigid part of the busbar and screws to lock it to the plastic bracket of the battery module. This point fixing method will generate huge stress concentration at the fixing point under long-term mechanical vibration and impact, which will easily cause the screws to loosen and make it difficult to disassemble and assemble, which will bring certain adverse effects to the use process. To this end, we propose a locking and fixing structure for FFC integrated busbars. Summary of the Invention

[0004] Technical Problem Solved: Addressing the shortcomings of existing technologies, this utility model provides a locking and fixing structure for an FFC integrated busbar, offering advantages such as easy assembly and disassembly, and quick positioning. The fixing ear is fitted onto the lower end of the outer wall of the through-hole control frame. A first silicone elastic pad at the lower end of the outer wall of the through-hole control frame enhances friction and buffering force. The anti-detachment positioning block can move within the inner wall of the inner movable groove through the action of the elastic element and the limiting movable plate. When the fixing ear is fitted onto the lower end of the outer wall of the through-hole control frame, the anti-detachment positioning block can be engaged and positioned on both sides of the upper end of the fixing ear. A second silicone elastic pad at the lower end of the anti-detachment positioning block enhances friction, allowing the anti-detachment positioning block to... The upper end of the fixing ear is not easy to loosen, and the engagement is more secure. The busbar conductor can be positioned in the middle of the upper end of the battery module plastic bracket. When disassembly or assembly is required, press the anti-disengagement positioning block to move it inward into the inner side of the movable groove, so that the through control frame is disengaged from the fixing ear. This completes the disassembly or assembly of the busbar conductor and the battery module plastic bracket, which is very convenient and quick. The operator does not need to use tools, which greatly shortens the installation time of a single connection point. When a busbar itself needs to be inspected or replaced, maintenance personnel can quickly and non-destructively disassemble it, avoiding problems such as stripping and rusting that may occur with traditional screw connections. This reduces maintenance difficulty, time and cost, and can effectively solve the problems in the background technology.

The second silicone elastic pad at the lower end of the anti-detachment positioning block can enhance friction. The friction ensures that the anti-detachment positioning block is not easily loosened at the upper end of the fixing ear, making the engagement more secure. The busbar conductor can be positioned in the middle of the upper end of the battery module plastic bracket. When disassembly or assembly is required, press the anti-detachment positioning block to move it inward into the inner side of the movable groove, so that the through control frame is disengaged from the fixing ear. This completes the disassembly or assembly of the busbar conductor and the battery module plastic bracket, which is very convenient and quick. Operators do not need to use tools, which greatly shortens the installation time of a single connection point. When a busbar itself needs to be inspected or replaced, maintenance personnel can quickly and non-destructively disassemble it, avoiding problems such as stripping and rusting that may occur with traditional screw connections, thus reducing maintenance difficulty, time and cost.

A first silicone elastic pad 8 is fixedly connected to the lower end of the outer wall of the through-control frame 7. An inner movable groove 9 is opened on the inner wall of the upper end of the through-control frame 7. A damper 10 and an elastic element 11 are positioned and installed on the inner wall of the inner movable groove 9. The damper 10 is located inside the elastic element 11 to provide elasticity.

[0021] Furthermore, both ends of the damper 10 and the elastic element 11 are fixedly connected to a limiting movable plate 12. A non-detachment positioning block 13 is fixedly connected to one side of the limiting movable plate 12. A second silicone elastic pad 14 is fixedly connected to the outer wall of the lower end of the non-detachment positioning block 13, which can enhance friction and improve the shock absorption effect.

[0022] Furthermore, the lower ends of the through-control frame 7 are fixedly connected to both sides of the upper end of the battery module plastic bracket 2. One side of the first silicone elastic pad 8 is attached and positioned to the lower end of the outer wall of the through-control frame 7 by strong adhesive. Both ends of the damper 10 and the elastic element 11 are fixedly connected to one side of the limiting movable plate 12.

[0024] Working Principle: A locking and fixing structure for an FFC integrated busbar. In use, the fixing ear 5 is fitted onto the lower end of the outer wall of the through-hole 6. The first silicone elastic pad 8 at the lower end of the outer wall of the through-hole 7 enhances friction and buffering force. The anti-detachment positioning block 13 can move within the inner wall of the inner movable groove 9 through the action of the elastic element 11 and the limiting movable plate 12. When the fixing ear 5 is fitted onto the lower end of the outer wall of the through-hole 7, the anti-detachment positioning block 13 can be locked and positioned on both sides of the upper end of the fixing ear 5.

The upper end of the fixed ear 5 is not easy to loosen, and the engagement is more secure. The busbar conductor 1 can be positioned in the middle of the upper end of the battery module plastic bracket 2. When disassembly or assembly is required, press the anti-disengagement positioning block 13 to move it inward to the inside of the movable groove 9, so that the through control frame 7 can be disengaged from the engagement of the fixed ear 5. This completes the disassembly or assembly of the busbar conductor 1 and the battery module plastic bracket 2, which is very convenient and quick. The operator does not need to use tools, which greatly shortens the installation time of a single connection point. When a busbar itself needs to be inspected or replaced, maintenance personnel can quickly and non-destructively disassemble it, avoiding problems such as stripping and rusting that may occur with traditional screw connections, and reducing maintenance difficulty, time and cost.
