Description
Technical Field
[0001] The utility model belongs to the technical field of battery cover plate sealing, and in particular relates to a battery cover plate structure. Background Art
[0002] At present, the sealing ring used in the existing battery cover is rectangular. On the one hand, the production cost of the rectangular sealing ring is high and the defective rate of the finished product is high during the production process; on the other hand, the upper end of the rectangular sealing ring extends to the gap between the pole hole and the pole of the battery cover. If it is subjected to lateral pressure multiple times, it will cause the rectangular sealing ring to fail. Therefore, it is necessary to improve the existing battery cover structure. The utility model provides a battery cover with a new structure, improves the sealing ring of the battery cover, and reduces the cost of the sealing ring; improves the insulating pad of the battery cover, so that the lower part of the insulating pad extends to the gap between the pole hole and the pole, avoiding the failure of the sealing ring due to multiple lateral forces. Utility Model Content
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a battery cover structure that solves the problems in the above-mentioned background technology.
[0004] The purpose of the utility model is achieved as follows: a battery cover structure, which includes a plate body, a column through hole is arranged on the plate surface of the plate body, a pole is arranged inside the column through hole, a sealing ring and an insulating pad are arranged between the column through hole and the pole, and the sealing ring is an O-ring; the insulating pad includes an upper vertical section, a middle horizontal section and a lower vertical section; an arc groove corresponding to the sealing ring is opened on the side wall of the column body of the pole; and an oblique angle portion corresponding to the sealing ring is provided on the side wall of the column through hole.
[0005] Furthermore, the column through hole includes a positive electrode through hole and a negative electrode through hole, the electrode column includes a positive electrode column and a negative electrode column, the positive electrode column is arranged inside the positive electrode through hole, and the negative electrode column is arranged inside the negative electrode through hole.
[0006] Furthermore, the sealing ring is made of rubber.
[0007] Furthermore, the insulating pad is made of plastic.
[0008] Furthermore, the upper vertical section, the middle horizontal section and the lower vertical section are integrally formed, and the lower vertical section extends to the inside of the gap between the column through hole and the pole.
[0009] Furthermore, the beveled portion is integrally formed with the plate body, and is formed by chamfering the lower end of the column through hole of the plate body.
[0010] The beneficial effects of the utility model are as follows: by setting the sealing ring as an O-ring, the O-ring is easy to process and produce, the yield of the sealing ring in the production process is improved, and the production cost of the sealing ring is reduced. The original rectangular sealing ring costs about 0.3 yuan per piece, and after changing to an O-ring sealing ring, the cost is about 0.15 yuan per piece, and the cost is reduced to half of the original. By setting the insulating pad in the structural form of an upper vertical section, a middle horizontal section and a lower vertical section, the lower vertical section is used to insert into the gap between the pole hole and the pole. The prior art is to insert the upper part of the sealing ring into the gap between the pole hole and the pole. Compared with the prior art, the hardness of the insulating pad is higher than that of the sealing ring. Therefore, when subjected to a lateral force, the lateral force directly acts on the lower vertical section of the insulating pad, rather than on the sealing ring, thereby protecting the sealing ring and avoiding failure of the sealing ring. The sealing effect of the sealing ring is enhanced by the provision of the arc groove and the bevel portion. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings. It should be pointed out that all directional words such as up, down, front, back, left, and right that appear in the present invention do not limit the present invention, but are only for the purpose of more clearly describing and explaining the present invention.

[0020] In this embodiment, the sealing ring 3 is set as an O-ring, which is easy to process and produce, thereby improving the yield rate of the sealing ring 3 in the production process and reducing the production cost of the sealing ring 3. The original rectangular sealing ring 3 costs about 0.3 yuan each, and the cost of the O-ring sealing ring 3 is about 0.15 yuan each, which is half of the original cost. By setting the insulating pad 4 to the structural form of the upper vertical section 5, the middle horizontal section 6 and the lower vertical section 7, the lower vertical section 7 is used to insert into the gap between the pole 2 hole and the pole 2. The prior art is to insert the upper part of the sealing ring 3 into the gap between the pole 2 hole and the pole 2. Compared with the prior art, the hardness of the insulating pad 4 is higher than that of the sealing ring 3. Therefore, when subjected to the lateral force, the lateral force directly acts on the lower vertical section 7 of the insulating pad 4, rather than on the sealing ring 3, which plays a role in protecting the sealing ring 3 and avoiding the failure of the sealing ring 3. The sealing effect of the sealing ring 3 is enhanced by the arrangement of the arc groove 8 and the bevel portion 9. Example

The positive pole column is arranged inside the positive through hole, and the negative pole column is arranged inside the negative through hole.
[0023] For better effect, the sealing ring 3 is made of rubber.
[0024] For better effect, the insulating pad 4 is made of plastic.
[0025] In this embodiment, the sealing ring 3 is set as an O-ring, which is easy to process and produce, thereby improving the yield rate of the sealing ring 3 in the production process and reducing the production cost of the sealing ring 3. The original rectangular sealing ring 3 costs about 0.3 yuan each, and the cost of the O-ring sealing ring 3 is about 0.15 yuan each, which is half of the original cost. By setting the insulating pad 4 to the structural form of the upper vertical section 5, the middle horizontal section 6 and the lower vertical section 7, the lower vertical section 7 is used to insert into the gap between the pole 2 hole and the pole 2. The prior art is to insert the upper part of the sealing ring 3 into the gap between the pole 2 hole and the pole 2. Compared with the prior art, the hardness of the insulating pad 4 is higher than that of the sealing ring 3. Therefore, when subjected to the lateral force, the lateral force directly acts on the lower vertical section 7 of the insulating pad 4, rather than on the sealing ring 3, which plays a role in protecting the sealing ring 3 and avoiding the failure of the sealing ring 3. The sealing effect of the sealing ring 3 is enhanced by the arrangement of the arc groove 8 and the bevel portion 9. Example

[0027] For better effect, the column through hole includes a positive through hole and a negative through hole, and the pole 2 includes a positive pole column and a negative pole column. The positive pole column is arranged inside the positive through hole, and the negative pole column is arranged inside the negative through hole.
[0028] For better effect, the sealing ring 3 is made of rubber.
[0029] For better effect, the insulating pad 4 is made of plastic.
[0030] For better effect, the upper vertical section 5 , the middle horizontal section 6 and the lower vertical section 7 are formed as one piece, and the lower vertical section 7 extends to the inside of the gap between the column through hole and the pole 2 .
[0031] In order to achieve a better effect, the beveled portion 9 is integrally formed with the plate body 1 , and the beveled portion 9 is formed by chamfering the lower end of the column through hole of the plate body 1 .
[0032] In this embodiment, the sealing ring 3 is set as an O-ring, which is easy to process and produce, thereby improving the yield rate of the sealing ring 3 in the production process and reducing the production cost of the sealing ring 3. The original rectangular sealing ring 3 costs about 0.3 yuan each, and the cost of the O-ring sealing ring 3 is about 0.15 yuan each, which is half of the original cost. By setting the insulating pad 4 to the structural form of the upper vertical section 5, the middle horizontal section 6 and the lower vertical section 7, the lower vertical section 7 is used to insert into the gap between the pole 2 hole and the pole 2. The prior art is to insert the upper part of the sealing ring 3 into the gap between the pole 2 hole and the pole 2. Compared with the prior art, the hardness of the insulating pad 4 is higher than that of the sealing ring 3. Therefore, when subjected to the lateral force, the lateral force directly acts on the lower vertical section 7 of the insulating pad 4, rather than on the sealing ring 3, which plays a role in protecting the sealing ring 3 and avoiding the failure of the sealing ring 3. The sealing effect of the sealing ring 3 is enhanced by the arrangement of the arc groove 8 and the bevel portion 9.
