Description

Technical Field

[0001] The utility model relates to a CCS component, in particular to a CCS component with an improved separator structure for limiting aluminum bars. Background Art

[0002] The CCS (Cells Contact System) component in a new energy power battery module plays a very important role. The traditional wire harness CCS component usually uses a thermal fixing method to fix aluminum bars. However, this method not only requires designing a thermal riveting tooling, but also consumes a large amount of man-hours. There is a risk of thermal riveting column breakage in thermal riveting fixation. If the reserved space is unreasonable, it will also cause the thermal riveting head to crush the aluminum bar and the injection-molded separator.

[0003] With the rapid development of new energy vehicles, the weight requirements for vehicle components are becoming more and more strict. As a key component of new energy vehicles, the weight reduction and cost reduction of the new energy power battery module will play a crucial role. Therefore, the improvement of the wire harness CCS component is particularly important. Summary of the Utility Model

[0004] In order to solve the deficiencies of the above technologies, the utility model provides a CCS component with an improved separator structure for limiting aluminum bars.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is a CCS component with an improved separator structure for limiting aluminum bars, including a separator. A plurality of aluminum bar installation openings are reserved on the side edge of the separator. A U-shaped limiting buckle is arranged beside each aluminum bar installation opening. The U-shaped limiting buckle extends horizontally on the side edge of the separator. Two adjacent U-shaped limiting buckles on the side edge are arranged oppositely and jointly clamp the aluminum bar through a clamping interface.

[0006] A wire harness groove is provided on the separator. The wire harness groove is connected to the aluminum bar installation opening and a cable is arranged in the groove. A wire harness baffle is connected above the wire harness groove.

[0007] Further, there are a plurality of aluminum bar installation openings, which are formed between two adjacent vertical plates on the side edge of the separator. The plurality of aluminum bar installation openings are distributed on two symmetric side edges of the separator along the length direction.

[0008] Further, the U-shaped limiting buckle includes an upper clamping plate and a lower clamping plate arranged horizontally, and a connecting plate arranged vertically and connecting the upper clamping plate and the lower clamping plate up and down. The clamping interface is formed between the upper clamping plate, the lower clamping plate and the connecting plate.

[0009] Further, clamping convex points are arranged on both the upper clamping plate and the lower clamping plate. The clamping convex points between the upper clamping plate and the lower clamping plate of the same U-shaped limiting buckle are arranged corresponding to each other in the up and down positions.

[0010] Further, the upper and lower clamping plates of the lower clamping plate are connected to the vertical plates on the same side, and the connecting plate is located on the side away from the aluminum bar installation opening.

[0011] The utility model discloses a CCS component with an improved isolation plate structure for limiting aluminum bars, adopting a new fixing method to replace the traditional hot riveting fixing. By adopting the new fixing method, the need for designing a hot riveting tooling is reduced, and the working hours can also be saved. In addition, the new fixing method can also reduce the risk of hot riveting column fracture and avoid the crushing damage caused by the hot head to the aluminum bar and the injection-molded isolation plate. At the same time, it also has the advantages of reducing costs, improving the performance and safety of the battery module, simple structure, easy manufacturing and maintenance, and strong adaptability.

Detailed Embodiment

[0016] The following further elaborates on the utility model in detail in conjunction with the drawings and specific embodiments.

[0017] As Figures 1-3 shown, the CCS component with an improved isolation plate structure for limiting aluminum bars includes an isolation plate 100. The isolation plate 100 plays a role of isolation and support in the CCS component. It provides effective insulation for the connection between battery modules and at the same time supports the battery modules to prevent deformation of the battery modules. Multiple aluminum bar installation openings 200 are reserved on the side edges of the isolation plate 100. Each aluminum bar installation opening 200 is formed between two adjacent vertical plates 101 on the side edge of the isolation plate 100, and the multiple aluminum bar installation openings 200 are distributed on two symmetric side edges of the isolation plate 100 along the length direction.

[0018] A U-shaped limit buckle 300 is provided on the side of each aluminum bar installation opening 200. The U-shaped limit buckle 300 extends horizontally on the side edge of the isolation board 100. Two adjacent U-shaped limit buckles 300 on the side edge are arranged oppositely and jointly clamp the aluminum bar 400 through the clamping interface. Specifically, the U-shaped limit buckle 300 includes an upper clamping plate 301 and a lower clamping plate 302 arranged horizontally, and a connecting plate 303 arranged vertically and connecting the upper clamping plate 301 and the lower clamping plate 302 up and down. The clamping interface is formed between the upper clamping plate 301, the lower clamping plate 302 and the connecting plate 303. In order to improve the clamping effect of the clamping interface on the aluminum bar 400, clamping convex points 304 are provided on both the upper clamping plate 301 and the lower clamping plate 302. The clamping convex points 304 between the upper clamping plate 301 and the lower clamping plate 302 of the same U-shaped limit buckle 300 are arranged corresponding to each other in the up and down positions and are clamped with the aluminum bar 400 through the contact of the clamping convex points 304. It should be noted here that the upper clamping plate 301 and the lower clamping plate 302 can be made of elastic materials.

[0019] At the same time, the side of the upper clamping plate 301 and the lower clamping plate 302 of the lower clamping plate 302 is connected to the vertical plate 101. The connecting plate 303 is located on the side far from the aluminum bar installation opening 200, so that the two opposite clamping interfaces can achieve the effect of clamping the aluminum bar left and right. It should be noted that the U-shaped limit buckle 300 can play a role in clamping the aluminum bar, but it is not the only clamping method. In fact, the aluminum bar installation opening 200 and the aluminum bar 200 can also be used in cooperation with the U-shaped limit buckle 300 by setting a bayonet or abutting method to further stabilize the aluminum bar.

[0020] A wire harness groove 500 is provided on the isolation board 100. In this embodiment, the wire harness groove 500 is arranged along the length direction of the isolation board 100. The wire harness groove 500 is connected to the aluminum bar installation opening 200 and a cable 700 is arranged in the groove. A wire harness baffle 600 is connected above the wire harness groove 500 for clamping the cable 700.

[0021] The CCS component with an improved isolation board structure for limiting the aluminum bar has the following advantages: improving production efficiency and safety: by adopting a new fixing method, the component reduces the need for the traditional hot riveting fixing method, saves working hours, reduces the risk of hot riveting column fracture, and avoids the pressing damage to the aluminum bar and the injection-molded isolation board caused by the hot head. At the same time, since the need for the hot riveting fixing method is reduced, the production cost can be reduced. At the same time, since this component is a key part of new energy vehicles, reducing its weight is very important for improving vehicle performance and reducing energy consumption. The clamping effect of the aluminum bar is improved. By adopting the method of clamping the aluminum bar through the contact of the clamping convex points, the clamping effect of the aluminum bar is improved, thereby improving the overall performance and stability of the CCS component.

[0022] The above embodiments are not limitations to the present utility model, nor is the present utility model limited to the above examples. Any changes, modifications, additions or substitutions made by those skilled in the art within the technical scope of the present utility model also fall within the protection scope of the present utility model.
