Housing with explosion-proof valve and power cell

Abstract

The utility model provides a kind of shell with explosion-proof valve and power battery.The shell with explosion-proof valve has side wall and bottom wall and is enclosed to form the cavity of accommodating electric core, bottom wall has opposite inner surface and outer surface, bottom wall includes base body, explosion-proof valve body and connecting body.Base body connects side wall, bottom wall is formed explosion-proof valve body by thinning treatment from inner surface to outer surface direction, connecting body is between base body and explosion-proof valve body.Explosion-proof valve body and connecting body are enclosed to form cavity, the outer surface of explosion-proof valve body is recessed to form notch in inner surface direction, and notch is connected to connecting body.This structure is equivalent to the original sheet structure of bottom wall by thinning to form explosion-proof valve body, which will not affect the internal space of shell.The side of explosion-proof valve body forms the cavity that can store gas, the opposite side forms notch, and notch is located at the weakest position of explosion-proof valve body, so the sensitivity of explosion is higher due to the influence of internal and external structures, which can facilitate explosion when air pressure reaches preset value.
