[0022] Reference Figure 1-2 The image shown is a preferred embodiment of the present invention.

[0023] The anti-rotation structure includes a top cover plate 300, a pole 100, and an upper plastic part 200 arranged in a ring. The pole 100 is inserted into the top cover plate 300 and has a rubber-coated section 101 extending above the top cover plate 300. The upper plastic part 200 is injection molded on the top cover plate 300 and wraps around the outer periphery of the rubber-coated section 101. The outer periphery of the rubber-coated section 101 and the upper plastic part 200 are in concave-convex contact.

[0024] After the pole post 100 is inserted into the top cover plate 300, the rubber-coated section 101 is exposed above the top cover plate 300. By injecting glue into the top cover plate 300, an upper plastic part 200 is formed on the top cover plate 300, and the upper plastic wraps around the outer periphery of the rubber-coated section 101.

[0025] The above-mentioned anti-rotation structure for the pole post has an upper plastic part 200 fixedly formed on the top cover plate 300 and wrapping the rubber-coated section 101 of the pole post 100. The upper plastic part 200 and the rubber-coated section 101 are in concave-convex contact, so that the rubber-coated section 101 and the upper plastic part 200 form a stable overall structure, which greatly enhances the anti-rotation effect of the pole post 100.

[0026] In this embodiment, the outer periphery of the overmolded section 101 is provided with a plurality of groove strips 103, and the upper plastic part 200 has an inner ring sidewall facing the upper component, and the inner ring sidewall is formed with a plurality of protruding strips; the protruding strips are embedded in the groove strips 103, and the inner ring sidewall is in a concave-convex shape abutting against the outer periphery of the overmolded section 101.

[0027] The strip-shaped interlocking between the groove strip 103 and the raised strip allows for a longer length of concave-convex contact, making the connection between the upper plastic part 200 and the rubber-coated section 101 more stable.

[0028] In this embodiment, the groove strip 103 extends along the height direction of the overmolded section 101, and the raised strip extends along the height direction of the inner ring sidewall. This facilitates the fit between the overmolded section 101 and the upper plastic part 200. After the glue is injected onto the top cover plate 300, the glue is more easily embedded in the groove strip 103, forming a raised strip in the groove strip 103, so that the fit between the overmolded section 101 and the upper plastic part 200 is stable.

[0029] In this embodiment, the top of the groove strip 103 extends to the top of the overmolded section 101, and the bottom of the groove strip 103 extends to the bottom of the overmolded section 101. Thus, the groove strip 103 forms a through-and-through shape, facilitating the embedding of the upper plastic part 200 within the groove strip 103.

[0030] In this embodiment, multiple groove strips 103 are arranged at intervals around the outer periphery of the overmolded section 101. This ensures that multiple groove strips 103 are distributed around the outer periphery of the overmolded section 101. When the upper plastic part 200 mates with the overmolded section 101, a concave-convex abutment is formed throughout the entire circumference, thereby achieving full circumferential limitation of the overmolded section 101.

[0031] A raised spacer 102 is formed between adjacent grooved strips 103. The spacer 102 is embedded in the inner ring sidewall. The spacer 102 and the grooved strips 103 are arranged alternately along the circumferential direction of the rubber-coated section 101 to form a gear shape.

[0032] In this embodiment, the outer periphery of the spacer 102 is arc-shaped, which facilitates the formation of the overmolded section 101 and the fit between the upper plastic part 200 and the overmolded section 101.

[0033] In this embodiment, the top cover plate 300 is provided with a hole through which the pole post 100 passes, and the top cover plate 300 is provided with a surrounding wall 301. The surrounding wall 301 surrounds the outer periphery of the rubber-coated section 101 and has an injection gap between it and the rubber-coated section 101. The upper plastic part 200 has an inner section 201 embedded in the injection gap. The inner section 201 wraps around the outer periphery of the rubber-coated section 101 and abuts against the outer periphery of the rubber-coated section 101 in a concave-convex manner.

[0034] During the process of injecting glue into the top cover plate 300 to form the upper plastic part 200, the glue is embedded in the injection interval, forming an inner section 201 in the injection interval. The inner section 201 wraps around the outer periphery of the glue-coated section 101, which facilitates the formation of the inner section 201. The inner section 201 is combined with the enclosing wall 301 to ensure that the upper plastic part 200 is fixed on the top cover plate 300.

[0035] In this embodiment, the upper plastic part 200 has an outer section 202 surrounding the outer periphery of the enclosure wall 301. The outer section 202 wraps around the outer periphery of the enclosure wall 301. The upper part of the enclosure wall 301 is bent toward the rubber-coated section 101 to form a bent portion 302. The bent portion 302 is embedded in the inner section 201.

[0036] The inner section 201 of the upper plastic part 200 is located inside the enclosure wall 301, and the outer section 202 wraps around the outer side of the enclosure wall 301, thereby forming a clamping and fixing of the enclosure wall 301 inside and out. The upper plastic part 200 and the enclosure wall 301 are an integral structure, so that it is fixed on the top cover plate 300.

[0037] This embodiment also provides a battery cover, which includes the above-mentioned anti-rotation structure of the terminal post. The terminal post 100 and the upper plastic part 200 are combined to form a stable integrated structure. The terminal post 100 is also combined with the top cover 300 to form a stable integrated structure, which has a better anti-rotation effect and ensures the quality of the battery cover.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
