Technical Field

[0001] The utility model relates to the technical field of battery cover plates, in particular to an anti-rotation riveted top cover structure. Background Art

[0002] The riveted top cover of the battery is usually a step in the battery assembly process, which is used to ensure the fixed connection and sealing between the battery top cover and the battery shell. It includes a top cover sheet, a pole, a seal and a first plastic part. The top cover sheet is provided with a plurality of rivets, and the pole is correspondingly provided with rivet holes. A gap is formed between the rivet parts and the rivet holes. The first plastic part is injection molded on the pole and has an injection molded connection portion that fits in the gap. The advantage of this structure is that it is easy to manufacture and the structural strength of the pole is good.

[0003] At present, most of the riveted cover plates have convex points and blind holes in the aluminum sheet to reduce the left and right shaking of the lower plastic, but it will cause the following problems

[0004] Affecting the appearance: After the blind holes are punched on the back of the aluminum sheet, the front side will be squeezed out, resulting in different colors and bulges in the raw materials;

[0005] Impact on subsequent processes: Different colors will affect the subsequent coding process, resulting in unclear coding and abnormal code scanning.

[0006] Therefore, it is necessary to provide an anti-rotation riveted top cover structure to solve the above technical problems. Utility Model Content

[0007] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an anti-rotation riveted top cover structure to solve the problem that after the blind holes are punched on the back of the existing smooth aluminum sheet, material extrusion will occur on the front side, resulting in different colors and protrusions of the raw materials. The different colors will affect the subsequent coding process, the coding is not clear, and the code scanning is abnormal.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0009] An anti-rotation riveted top cover structure, comprising: a pole, a plain aluminum sheet, a lower plastic, a riveted aluminum block, an upper plastic, and a sealing ring;

[0010] A riveted aluminum block is installed on the outer peripheral side of the pole, an upper plastic is installed between the riveted aluminum block and the plain aluminum sheet, the bottom of the plain aluminum sheet abuts against the top surface of the lower plastic, a sealing ring is installed on the bottom of the outer peripheral surface of the pole, an anti-rotation groove is provided on the bottom surface of the plain aluminum sheet, and the anti-rotation groove is a rectangular pit structure, and a positioning block is provided on the top surface of the lower plastic, and the positioning block is matched with the anti-rotation groove.

[0011] In one embodiment, the anti-rotation groove has a long side left side and a long side right side.

[0012] In one embodiment, the positioning block has a left limiting edge and a right limiting edge.

[0013] In one embodiment, the positioning block and the anti-rotation groove are close to the pole center hole in the middle of the width.

[0014] In one embodiment, the length of the positioning block is smaller than the length of the anti-rotation groove.

[0015] The beneficial effects of the utility model are as follows:

[0016] (1) The utility model uses the anti-rotation groove and the positioning block to cooperate with each other, so that the anti-rotation mechanism is hidden under the aluminum block, which has no effect on the appearance of the product and improves the appearance of the product.

[0017] (2) The utility model greatly expands the range of the coding and helium inspection sealing areas that can be selected in the subsequent process by coordinating the anti-rotation groove with the positioning block, thereby improving the selectivity of the coding and helium inspection processes in the subsequent process.

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0024] like Figure 1-Figure 4 As shown, the utility model provides an anti-rotation riveted top cover structure, comprising: a pole 10, a plain aluminum sheet 20, a lower plastic 30, a riveted aluminum block 40, an upper plastic 50, and a sealing ring 60;

[0025] like Figure 1-Figure 4As shown, a riveted aluminum block 40 is installed on the outer peripheral side of the pole 10, an upper plastic 50 is installed between the riveted aluminum block 40 and the plain aluminum sheet 20, the bottom of the plain aluminum sheet 20 abuts against the top surface of the lower plastic 30, a sealing ring 60 is installed on the bottom of the outer peripheral surface of the pole 10, and an anti-rotation groove 202 is provided on the bottom surface of the plain aluminum sheet 20. The anti-rotation groove 202 is a rectangular pit structure, which plays the role of avoiding the raised structure on the lower plastic after the pole is riveted. A positioning block 302 is provided on the top surface of the lower plastic 30, and the positioning block 302 is matched with the anti-rotation groove 202. The positioning block 302 is inserted into the anti-rotation groove 202 to achieve an anti-rotation effect.
