Description

Technical Field

[0001] The utility model relates to a CCS component, in particular to an energy storage battery blister CCS component with a novel fixing structure. Background Art

[0002] The CCS assembly is a key component of new energy power battery modules. It's the control device that allows electric vehicle cruise control systems to automatically maintain a specific speed according to the driver's requirements, without the need to press the accelerator pedal. Traditional CCS assemblies utilize laser welding of the FPC assembly between a nickel sheet and an aluminum bar, secured by hot riveting. However, the hot riveting process cannot control the gap between the aluminum bar and the rivet head, requiring multiple hot riveting and laser processes, which can easily lead to defects. Furthermore, this multi-step process is inefficient and costly. Utility Model Content

[0019] The utility model discloses an energy storage battery blister CCS assembly with a novel fixing structure, the main structural components of which include a blister isolation plate 1, an FPC circuit board 2, an aluminum bar 3 and a nickel sheet 4;

[0020] Among them, the blister isolation plate 1 is used as an insulating structure for the arrangement of the FPC circuit board 2 and the aluminum bar 3;

[0021] First, the aluminum bar 3 is fixed on the blister isolation plate 1 by means of a buckle 5, specifically: Figure 1 As shown, the blister isolation plate 1 is formed with an aluminum bar groove 7 for mounting the aluminum bar 3. At the same time, the blister isolation plate 1 is formed with a buckle 5 structure for limiting and fixing the aluminum bar 3. Preferably, the buckle 5 is a tooth-shaped structure that extends along the top opening edge of the aluminum bar groove 7 to limit and fix the aluminum bar 3. Figure 2 As shown, after the aluminum bar 3 is installed in the aluminum bar groove 7, the buckle 5 structure limits the aluminum bar to buckle and fix the aluminum bar 3 in the aluminum bar groove 7 of the injection-molded isolation plate.

[0022] Secondly, the FPC circuit board 2 can be fixed on the blister isolation board 1 by a common pasting method.

Figure 2 As shown, through holes for the heat rivet studs 6 to pass through are respectively opened on the nickel sheet 4 and the aluminum bar 3, and the opening diameter of the through holes is larger than the diameter of the heat rivet studs 6. Therefore, the nickel sheet 4 and the aluminum bar 3 are positioned together by the heat rivet studs 6 for heat rivet fixation.

[0025] Preferably, the diameter of the heat rivet stud 6 is 5 mm, and the opening diameter of the through hole is 5.4 mm-5.5 mm.
