AI Technical Summary
Technical Problem
When the battery pack shakes, the electrolyte may impact the pressure relief valve, causing damage to the pressure relief valve or opening it in advance, increasing safety risks and affecting the service life.
Method used
A battery cover is designed, including a lower insulation and a buffer plate. The lower insulating member forms an exhaust hole opposite to the pressure relief valve. The buffer sheet covers the exhaust hole and has a ventilation structure to ensure smooth flow of gas and buffer the electrolyte flowing to the pressure relief valve.
Benefits of technology
Through this design, the impact of the electrolyte on the pressure relief valve is reduced, the service life of the pressure relief valve is extended, and the safety of the battery pack is improved.

Abstract
The utility model discloses a battery cover plate, a battery monomer and a battery pack. The battery cover plate comprises a cover plate body, a pressure release valve, a lower insulating part and a buffer plate, a valve mounting hole is formed in the cover plate body, the pressure release valve is mounted in the valve mounting hole, the lower insulating part is arranged on the inner side of the cover plate body and provided with an exhaust hole opposite to the pressure release valve, the buffer plate is located between the cover plate body and the lower insulating part and covers the exhaust hole, and a ventilation structure is formed on the buffer plate. According to the battery cover plate disclosed by the embodiment of the utility model, the exhaust hole opposite to the pressure release valve is formed in the lower insulating part, the buffer plate covers the exhaust hole, and the ventilation structure is formed on the buffer plate, so that a gas circulation channel is smooth by the ventilation structure, and normal pressure release of the pressure release valve can be ensured; and the buffer plate can play a role in buffering the electrolyte flowing to the pressure release valve, so that the possibility that the pressure release valve is damaged or the pressure release valve is opened in advance due to the impact of the electrolyte on the pressure release valve can be reduced, and the service life of the pressure release valve can be prolonged.
