The utility model provides an adjustable gasket for lithium-ion battery extrusion, which relates to the field of gasket technology, including a main gasket and a secondary gasket, wherein a slurry storage area is provided at the connection between the main gasket and the secondary gasket, and the number of the secondary gaskets is two groups, wherein the secondary gasket is slidably connected to the main gasket, and the main gasket and the secondary gasket are staggered. In the utility model, by providing a main gasket, a secondary gasket and a slurry storage area, the secondary gasket is pushed to the left or right to slide on the main gasket, and after sliding a certain distance, the secondary gasket is pressed hard to fix the secondary gasket with the main gasket, and then the slurry is injected into the slurry storage area formed between the main gasket and the secondary gasket, and the slurry is cooled after injection. The structure can effectively prevent the main gasket and the secondary gasket from easily moving and leaking during operation, thereby improving the installation effect between the main gasket and the secondary gasket.

Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, in particular to an adjustable gasket for extrusion of a lithium ion battery. Background Art

[0002] Lithium-ion battery compression gaskets are an important component used to provide proper extrusion force in battery assembly. They are usually placed at the end or around the battery stack to ensure good contact and stability between the various components in the battery. In general, lithium-ion battery compression gaskets play an important role in battery manufacturing, helping to improve battery performance, safety and life by providing proper extrusion force and stability. Existing compression gaskets currently have one gasket for each model, or other adjustable ones are easy to move and leak during installation, so they need to be improved. Utility Model Content

[0003] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0004] The utility model adopts the following technical scheme: a lithium-ion battery extrusion adjustable gasket comprises a main gasket and a secondary gasket, and a slurry storage area is arranged at the connection between the main gasket and the secondary gasket.

[0005] Preferably, the number of the auxiliary gaskets is two groups. Here, two groups of auxiliary gaskets make it convenient for operators to assemble them with the main gasket.

[0006] Preferably, the secondary gasket is slidably connected to the main gasket. Here, the adjustment effect between the secondary gasket and the main gasket is improved by the sliding connection.

[0007] Preferably, the main gasket and the auxiliary gasket are staggered. Here, the staggered distribution prevents the auxiliary gasket from deviating outwards.

[0008] Compared with the prior art, the advantages and positive effects of the utility model are:

[0009] In the utility model, a main gasket, a sub-gasket and a slurry storage area are provided, and the sub-gasket is pushed to the left or right to slide on the main gasket. After sliding a certain distance, the sub-gasket is pressed hard to fix the sub-gasket and the main gasket. Subsequently, the slurry is injected into the slurry storage area formed between the main gasket and the sub-gasket, and the slurry is waited for to cool after injection. This structure can effectively prevent the main gasket and the sub-gasket from easily moving and leaking during operation, thereby improving the installation effect between the main gasket and the sub-gasket.

[0013] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0014] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0015] Embodiment 1

[0016] See also Figure 1 The utility model provides a technical solution: a lithium-ion battery extrusion adjustable gasket, including a main gasket 1 and a sub-gasket 2, and a slurry storage area 3 is provided at the connection between the main gasket 1 and the sub-gasket 2. By providing the main gasket 1, the sub-gasket 2 and the slurry storage area 3, the sub-gasket 2 is pushed to the left or right to slide on the main gasket 1, and after sliding a certain distance, the sub-gasket 2 is pressed hard to fix the sub-gasket 2 with the main gasket 1, and then the slurry is injected into the slurry storage area 3 formed between the main gasket 1 and the sub-gasket 2, and the slurry is cooled after injection. This structure can effectively prevent the main gasket 1 and the sub-gasket 2 from easily moving and leaking during operation, thereby improving the installation effect between the main gasket 1 and the sub-gasket 2.

[0017] See also Figure 1 There are two groups of sub-gaskets 2. The two groups of sub-gaskets 2 make it convenient for operators to assemble them with the main gasket 1. The sub-gasket 2 is slidingly connected to the main gasket 1. The sliding connection improves the adjustment effect between the sub-gasket 2 and the main gasket 1. The main gasket 1 and the sub-gasket 2 are staggered, and the staggered distribution prevents the sub-gasket 2 from shifting outward.

[0018] Working principle: When adjusting, first push one set of sub-gaskets 2 to the left or right to make the sub-gasket 2 slide on the main gasket 1. After sliding a certain distance, press the sub-gasket 2 hard to make the sub-gasket 2 and the main gasket 1 fixed. Then inject the slurry into the slurry storage area 3 formed between the main gasket 1 and the sub-gasket 2. After injection, wait for the slurry to cool down. After cooling, install another set of sub-gaskets 2 as above.

[0019] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
