Description

Technical Field

[0001] The utility model relates to a protection structure, in particular to a protection structure of a battery CCS output pole component. Background Art

[0002] The CCS output pole assembly is an important component of the new energy power battery module. Due to structural limitations, the traditional output pole assembly cannot use traditional heat shrink tubes to achieve product insulation protection. It is mostly outsourced to a third-party unit for insulation treatment such as powder dipping, powder spraying, and plastic dipping. This method requires the outsourced supplier to handle the product after ultrasonic welding. Because the output pole assembly is a key electrical connector, the product has high requirements for tension, peeling force, cleanliness and appearance. After outsourced transportation and processing, the appearance, tension, peeling force and cleanliness must be inspected again before delivery or installation of the CCS assembly. However, this method has the disadvantages of high cost and high risk of failure. With the rapid development of new energy vehicles, the quality and cost requirements of automotive parts are becoming more and more stringent, and the new energy power battery module, as the main component of new energy vehicles, plays a key role in improving reliability and reducing costs.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The utility model discloses a protection structure of a battery CCS output pole component, which is an injection molded part with special structural characteristics and has an insulation protection function. Figure 4-6 Protective cover shown.

[0025] For ease of description, the protective cover 1 is structured to include an upper limit plate 11, a lower limit plate 12, an upper limit structure 13, an installation limit buckle 14, a short side wall 16, and a displacement side wall 17;

[0026] The upper limit plate 11 and the lower limit plate 12 together separate a protective space, which is used for the output pole 2 to be inserted and installed. The protective cover 1 is installed by interference fit on the exposed surface of the output pole to achieve protection and fixation. Figure 7 As shown, the output pole 2 is formed by ultrasonic welding of copper bar 21 and aluminum bar 22, which plays the role of transmitting the total current of the module. Copper bar 21 is a nickel-plated copper product, which connects copper busbar and aluminum bar for current transmission; aluminum bar is pure aluminum material, which connects battery cells for current transmission.

[0027] The state of the protective cover 1 when it is installed with interference fit on the output pole is as follows Figure 1-3 As shown, specifically: the entire upper limit plate 11 is in the shape of a flat plate, and is folded downward along one end of the upper limit plate 11 to form an upper limit structure 13, and the upper limit structure 13 is used to limit one side of the copper bar 21; the upper limit plate 11 and the lower limit plate 12 are integrally connected by a short side wall 16 on the opposite side of the upper limit structure 13.

[0028] The lower limit plate 12 has a step structure 15 adapted to the output pole 2, and a mounting limit buckle 14 is provided at a top corner of the lower limit plate 12, and the mounting limit buckle 14 plays a limiting role on one side of the copper bar 21. Accordingly, the upper limit plate 11 and the lower limit plate 12 are integrally connected on the opposite side of the mounting limit buckle 14 through a displacement side wall 17.

[0029] In addition, if Figure 3 As shown, an easy-to-break notch 18 is formed at one end of the displacement side wall 17 near the installation opening to facilitate quick installation and disassembly, and a limiting structure can be used to ensure that the protective cover is securely fixed and does not fall off after installation.

[0030] It can be seen that the protection structure of the battery CCS output pole assembly of the utility model has the following technical advantages compared with the prior art:

[0031] 1) The new output pole protection structure, i.e. the protective cover, replaces the traditional insulation treatment protection methods such as impregnation powder, effectively avoiding the transportation and inspection costs caused by outsourcing processing, eliminating the failure risk caused by multiple processing steps and product turnover, and improving the reliability of CCS component quality;

[0032] 2) The new output pole protection structure, i.e. the protective cover, can be quickly installed and disassembled, thus avoiding the scrapping of components and assembly products due to itself or other reasons;

[0033] 3) It effectively improves the compatibility of various accessories of CCS components, making its structure more coherent and simple, providing space for CCS components to be quickly installed and freely disassembled and reused after defective products are produced; by replacing traditional solutions with new protective structures, the weight and cost of CCS components can be reduced, providing effective support for weight reduction and cost savings of new energy power battery modules.

[0034] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
