Abstract

The invention relates to the technical field of batteries. The invention discloses a liquid injection hole protection structure of a battery top cover, the structure comprising a top cover sheet, a liquid injection plug and a sealing aluminum sheet, wherein the top cover sheet is provided with a liquid injection hole for pouring electrolyte into the battery interior, the liquid injection plug is embedded in the liquid injection hole and abuts against the side wall of the liquid injection hole, the sealing aluminum sheet is arranged on the outer sealing liquid injection hole of the top cover sheet, and the sealing aluminum sheet is fixedly connected with the top cover sheet; an upper positioning hole with an outer opening of the top cover piece on the liquid injection plug; the injection plug is plugged into the injection hole, and the sealing aluminum sheet is fixed on the top cover sheet, so as to realize the plugging of the injection hole and avoid leakage of electrolyte from the inside of the battery or entry of external impurities into the battery. When it is necessary to take out the liquid injection plug, the screw is drilled into the liquid injection hole and the positioninghole is aligned so that the screw is screwed into the liquid injection plug, thereby facilitating the maintenance and recovery of the battery, and the liquid injection plug can also be taken out after the sealing aluminum sheet welding fails, so as to facilitate the secondary processing.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to the liquid injection hole protection structure of the battery top cover. Background technique [0002] With the miniaturization and portability of electronic products, the use of batteries is becoming more and more extensive. This is because the battery structure is simple, easy to carry, easy to charge and discharge, not affected by the external climate and temperature, and its performance is stable and reliable. It plays an important role in all aspects of modern social life. [0003] In the prior art, the battery top cover covers the opening at the upper end of the casing, including a cover piece and two poles, the two poles are respectively set in the cover piece, and the inner ends of the poles extend to the inside of the casing, and The battery inside the housing is connected, and the outer end of the pole extends to the outside of the cover for connection with external ...
