Abstract
The utility model discloses a temperature control explosion-proof membrane equipment of a battery cell. The temperature control explosion-proof membrane equipment comprises an electrode panel, a deflation hole, post terminals, an explosion-proof membrane and a bed frame, wherein a heat conduction sheetmetal is arranged in the bed frame, a force storing spring is arranged between the side face of the heat conduction sheetmetal and the bed frame, a thermoplastic base resin cushion block which is used for counteracting the strain of the spring is arranged between the other side face of the heat conduction sheetmetal and the bed frame, the heat conduction sheetmetal is connected with one of the post terminals, a thimble slice is arranged between the heat conduction sheetmetal and the explosion-proof membrane, the cusp of the thimble slice is contacted and matched with the explosion-proof membrane, the blunt end of the thimble slice is connected with the heat conduction sheetmetal. When an unexpected condition (such as internal short of the battery cell) happens, a great deal of gas and heat is released, the temperature of the post terminals rises quickly, the thermoplastic base resin cushion block is heated by virtue of the heat conduction sheetmetal, the thermoplastic base resin cushion block is softened because of reaching the fusion point, and thus the shape change balance of the force storing spring is destroyed, the force storing spring compels that the explosion-proof membrane is punctured by the thimble slice, gas is exhausted after the explosion-proof membrane destroyed, and at last an explosion accident is prevented.
