Problems solved by technology

[0002] Nowadays, the steel shell structure of TWS electric core is more complicated and complicated than the soft package, so the manufacturing process is also complicated and the efficiency is low. not conducive to assembly
[0003] For example, in the process of assembling the cover assembly and the shell of the existing electric core, it can only be fixed by jigs, but the jigs cannot match each shell, and there are gaps between some of them, resulting in welding misalignment, thus Battery scrap

Abstract

The invention provides a TWS embedded surface cover steel shell battery cell. The TWS embedded surface cover steel shell battery cell comprises a shell, a roll core contained in the shell and a cover body assembly arranged on the shell, the cover body assembly comprises a cover body and a connecting piece arranged on the cover body, the cover body comprises a first cover body main body and a second cover body main body arranged on the first cover body main body in a protruding mode, the second cover main body is located on the surface, close to the shell, of the first cover main body, and the side portion of the second cover main body abuts against the inner surface of the shell. The TWS embedded surface cover steel shell battery cell provided by the invention is convenient to assemble.

Description

technical field [0001] The invention relates to a TWS mosaic steel case electric core with a face cover. Background technique [0002] Nowadays, the steel shell structure of TWS electric core is more complicated and complicated than the soft package, so the manufacturing process is also complicated and the efficiency is low. Not conducive to assembly. [0003] For example, in the process of assembling the cover assembly and the shell of the existing electric core, it can only be fixed by jigs, but the jigs cannot match each shell, and there are gaps between some of them, resulting in welding misalignment, thus The battery cell is scrapped. Contents of the invention [0004] Based on this, the present invention provides a TWS mosaic-type cover steel-case battery cell that is easy to assemble. [0005] A TWS mosaic-type surface-covered steel-case battery cell of the present invention includes a casing, a winding core accommodated in the casing, and a cover assembly provid...
