Abstract

The invention discloses a protective cover for a battery. The protective cover includes a cover body. At least one groove is disposed above the cover body. A protrusion is disposed on the outer side of the bottom of the groove. A through hole communicating with the groove is disposed on the protrusion. A liquid absorption column for extracting an electrolyte in the battery extends upward from thegroove at the position of the through hole. A liquid absorption hole is disposed in the liquid absorption column and communicates with the through hole. In the present invention, the protrusion is disposed on the bottom of the groove, and the protrusion does not have any notches and other holes except the through hole. Thus, the electrolyte cannot accumulate on the inner side of the cover body when absorbed so as to be smooth to absorb.

Description

Technical field [0001] The invention relates to the field of batteries, and more specifically to a protective cover for batteries. Background technique [0002] Existing batteries generally have a split structure, that is, the battery cover and the battery body are separated. During the production process, the battery body and the battery cover are produced separately. When the two are produced, they are assembled together, because the battery needs to work normally Electrolyte is needed. Therefore, electrolyte needs to be added to the battery body, but there may be too much electrolyte when adding electrolyte. Therefore, a certain amount of electrolyte needs to be sucked out through the liquid suction hole on the battery cover to meet the requirements. However, due to the unreasonable structure of the existing battery cover, there will be a backlog of electrolyte on the contact surface between the battery cover and the battery main body, which causes the electrolyte to be sucked...
