Description

Battery package pressure release valve gap board for car Technical Field The utility model relates to the technical field of battery pressure relief, in particular to a battery pack pressure relief valve cover plate for an automobile. Background During the charge or discharge of the battery pack, gas may be generated by internal chemical reactions, resulting in an increase in pressure. The pressure release valve cover plate can be automatically opened when the pressure reaches a certain threshold value, redundant gas is released, explosion or leakage caused by overhigh internal pressure is prevented, and the pressure release valve cover plate is an important component for ensuring safe and stable operation of a battery. The utility model patent with the grant bulletin number of CN213546508U discloses a pressure release valve and a battery pack, and particularly discloses a cover plate assembly, wherein the cover plate assembly comprises a cover plate which can be opened and closed at a discharge port of an exhaust channel far away from a pressure release port, and the cover plate has a closing state capable of being closed at the discharge port and an opening state capable of being opened when the pressure in the pressure release port is larger than a preset value; The pressure relief valve cover plate assembly disclosed by the above is not provided with an anti-falling structure, so that the pressure relief valve can possibly fall off from the pressure relief valve when the pressure relief valve has higher air pressure; accordingly, the application provides a battery pack pressure relief valve cover plate for an automobile. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, the utility model provides a battery pack pressure relief valve cover plate for an automobile, which solves the problem that the pressure relief valve cover plate assembly possibly falls off from the pressure relief valve to influence the working stability of the pressure relief valve when the pressure relief valve has higher air pressure due to the fact that the cover plate is not provided with an anti-falling structure in the prior art. In order to achieve the above purpose, the utility model provides a battery pack pressure release valve cover plate for an automobile, which comprises a cover body, wherein a through hole for installing a pressure release valve is formed in the cover body, injection molding grooves are symmetrically formed in the cover body, an aluminum bushing is fixedly arranged in each injection molding groove, a mounting groove is formed in the inner side of the cover body, and liquid silica gel is fixedly arranged in each mounting groove. As a further scheme of the utility model, the through hole is fixedly provided with an annular convex edge. As a further scheme of the utility model, a plurality of limiting plates are fixedly arranged on the periphery of the annular convex edge.
