Technical Field

[0001] This utility model patent relates to the technical field of top cover components, specifically to modular top cover components and batteries. Background Technology

[0002] The top cover assembly is an important component of the battery, and it includes various structures such as minimalist structure, one-piece encapsulation structure, and riveted structure.

[0003] In the existing technology, the assembly process of the top cover assembly is relatively complicated, resulting in an overly complex structure of the top cover assembly, which includes an upper electrode block, an upper plastic part, an electrode post, a top cover sheet, a sealing ring, and a lower plastic part. The electrode post is connected to the top cover sheet through the upper electrode block and riveting process. In addition, the electrode post is welded to the upper electrode block.

[0004] Once the riveted connection is completed, it is difficult to disassemble. When welding defects occur, the entire top cover assembly will be scrapped, increasing the scrap rate. At the same time, to meet the different requirements of different projects, the structure of each part of the top cover assembly needs to be redeveloped, increasing the time and cost of product redevelopment.

[0031] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0032] The modular top cover assembly includes a top cover piece 100 and an integrally assembled module body 200. The top cover piece 100 has a hollow area 101. The module body 200 includes a pole post 202, which is inserted into a connecting piece 203. The module body 200 covers the hollow area, and the outer periphery of the connecting piece 203 is closedly connected to the outer periphery of the hollow area 101.

[0033] The modular top cover assembly provided above uses an integrally assembled module body 200 directly installed in the hollow area 101 of the top cover plate 100. The module body 200 has pole posts 202, which has the following technical effects:

[0034] 1) The module body 200 is assembled as a whole. During the assembly of the top cover component, it is only necessary to install the module bodies 200 in the hollow area 101, which greatly simplifies the assembly process and makes the assembly convenient and simple.

[0035] 2) The components in module 200 can be designed to be reusable and can be reused in different projects, reducing repetitive work;

[0036] 3) The components in module 200 can be designed as common components, reducing the time and cost of redeveloping components and greatly reducing costs;

[0037] 4) The module body 200 is assembled as a whole, which makes it easier to adjust when meeting the needs of various projects. When the current capacity needs to be changed, only the size of the pole 202 needs to be changed, which improves the flexibility of use.

[0038] 5) When functional testing is required, only module 200 needs to be tested separately, reducing cost losses;

[0039] 6) Maintain a consistent production process and high yield rate.

[0040] In this embodiment, the outer periphery of the connecting piece 203 and the outer periphery of the hollow area 101 are connected by a stepped structure, which facilitates the assembly of the connecting piece 203 in the hollow area 101 and improves assembly efficiency.

[0041] In this embodiment, the stepped structure includes an upper step 102 formed on the outer periphery of the hollow area 101 and a lower step 204 formed on the outer periphery of the connecting piece 203, with the lower step 204 overlapping the upper step 102. When the module body 200 is assembled with the top cover piece 100, the module body 200 is directly placed in the hollow area 101, and the upper step 102 directly abuts against the lower step 204, thus achieving the initial assembly and positioning of the module body 200 and the hollow area 101.

[0042] In this embodiment, a limiting structure is provided between the outer periphery of the connecting piece 203 and the outer periphery of the hollow area 101, and the limiting structure restricts the connecting piece 203 from rotating circumferentially relative to the hollow area 101. In this way, when the module body 200 and the top cover piece 100 are assembled, the limiting structure can enhance the torque between the module body 200 and the top cover piece 100.

[0043] In this embodiment, the limiting structure includes a protrusion on the outer periphery of the connecting piece 203 and a groove on the outer periphery of the hollow area 101, with the protrusion embedded in the groove. The protrusion and groove form a convex-concave interlocking structure, which can prevent incorrect assembly.

[0044] In addition, the connecting piece 203 and the hollow area 101 are different in size. By forming a limiting fit between the protrusion and the groove, the assembly connection between the connecting piece 203 and the hollow area 101 can be achieved even when the operator is not focused or negligent.

[0045] In this embodiment, the outer periphery of the connecting piece 203 is provided with a plurality of the aforementioned protrusions, and the outer periphery of the hollow area 101 is provided with a plurality of the aforementioned grooves, with the plurality of protrusions respectively embedded in the plurality of grooves. The plurality of protrusions and the plurality of grooves are arranged at equal intervals along the circumferential direction, so that the connecting piece 203 and the top cover piece 100 form a multi-position limiting connection, which greatly improves the anti-torsion function of the module body 200.

[0046] In this embodiment, the top of the pole post 202 is exposed on the top of the module body 200, which facilitates the connection of the pole post 202 with external components.

[0047] In this embodiment, the pole post 202 includes a pole body 2021 and a lower pole block 2022. The lower pole block 2022 is located below the connecting piece 203, and a lower plastic part 207 is provided between the lower pole block 2022 and the connecting piece 203. An upper pole block 201 is provided above the connecting piece 203, and an upper plastic part 205 is provided between the upper pole block 201 and the connecting piece 203. The pole body 2021 passes through the lower plastic part 207, the connecting piece 203, the upper plastic part 205 and the upper pole block 201, and is exposed at the top of the upper pole block 201. A sealing ring 206 is provided between the pole body 2021 and the top cover piece 203.

[0048] In this way, the process of assembling individual components separately is eliminated. The pole post 202, upper plastic, sealing ring, connecting piece 203, lower plastic, and upper pole block 201 are assembled together as an integrated module 200 and connected to the top cover piece 100.

[0049] In this embodiment, the top of the connecting piece 203 is provided with a downward-facing recessed annular groove, which is arranged around the circumference of the column 2021. The lower part of the upper plastic part 205 is embedded in the annular groove, and the upper part of the upper plastic part 205 wraps around the outer periphery of the upper electrode block 201. This facilitates the positioning of the upper plastic part 205 on the connecting piece 203 and makes the connection between the upper plastic part 205 and the connecting piece 203 more stable.

[0050] This embodiment also provides a battery, including the modular top cover assembly described above.

[0051] The modular top cover assembly uses an integrated module body 200 and top cover piece 100 for assembly, which greatly improves the assembly efficiency of the top cover assembly, simplifies the assembly process, and saves assembly costs.

[0052] 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.
