Sealing structure of battery box

Abstract

The invention relates to the technical field of battery box sealing, and discloses a sealing structure of a battery box. The sealing structure of the battery box comprises a novel sealing ring, a box body, a tray and a battery, wherein the novel sealing ring is fixedly mounted at the bottom part of the sidewall of the box body; the bottom part of the battery is in contact with the top part of the tray; the top part of the battery is in contact with the top part of an inner chamber of the box body; and the bottom prat of the box body is clamped to the top part of the tray. According to the sealing structure of the battery box, a T-shaped groove and the upper edge of the novel sealing ring are clamped to each other, so that the novel sealing ring cannot be separated from the box body while the box body moves up and down, and as a result, the sealing effect of the novel sealing ring to the sealing structure is prevented from being influenced by the separation of the novel sealing ring and the box body; a plurality of ventilating holes communicate with inflating grooves in the novel sealing ring, so that the sealing structure is applicable to positive and negative pressure conditions and realizes sealing through the novel sealing ring.

Description

technical field [0001] The invention relates to the technical field of battery box sealing, in particular to a battery box sealing structure. Background technique [0002] With the continuous consumption of non-renewable energy and the increasing shortage of non-renewable energy, countries around the world are stepping up the pace of developing new energy. Among them, the lithium battery industry is advancing by leaps and bounds. However, the lithium battery manufacturing process is complicated and numerous, and the efficiency is limited and it is difficult to meet the demand. For example, lithium batteries In the cylindrical battery, one of the link liquid injection process, the battery absorption needs to stand still, the standing time period is long, how to improve the absorption efficiency of the battery is imminent. [0003] In the prior art, vacuum is generally used to stand still, and the box where the battery is placed is vacuumed so that the electrolyte inside the b...
