Technical Field
The invention relates to the technical field of lithium batteries, in particular to a crescent explosion-proof valve for a circular cover plate of a lithium battery.
Background
Lithium batteries are widely applied to electric vehicles, standby power systems and microgrid energy storage systems due to the advantages of high energy density, long service life and the like; in consideration of safety, an explosion-proof hole is usually formed in the lithium battery cover plate, an explosion-proof valve and an explosion-proof valve patch are installed in the explosion-proof hole, when the internal pressure of the battery reaches a certain value, the explosion-proof valve patch is opened to release the internal pressure of the battery, and the internal pressure of the battery is prevented from being further increased to cause battery explosion. The explosion-proof hole on the circular cover plate of the existing lithium battery is of a circular structure and is arranged on the periphery of a circular cover plate central circular hole, and the relative explosion-proof valve is also of a circular ring structure.
Disclosure of Invention
The invention aims to solve the technical problem of providing a crescent explosion-proof valve for a circular cover plate of a lithium battery, which is in a crescent annular plate structure, so that the explosion-proof area is greatly increased, and the explosion point stability of the explosion-proof valve is improved.
The technical scheme of the invention is as follows:
the utility model provides a circular for apron crescent explosion-proof valve of lithium cell, crescent explosion-proof valve be crescent annular plate structure, crescent explosion-proof valve's hole is the crescent through-hole, when crescent explosion-proof valve connects on the circular apron of lithium cell, crescent explosion-proof valve's crescent towards the centre of a circle of the circular base plate of circular apron.
The outer wall of the crescent explosion-proof valve and the positions at two ends of the crescent explosion-proof valve are both arc surface structures.
The inner wall of the crescent explosion-proof valve and the positions at two ends of the crescent through hole are both arc surface structures.
The crescent explosion-proof valve is always consistent in width from one end to the outer ring of the other end, and the crescent explosion-proof valve is always consistent in width from one end to the inner ring of the other end.
Crescent explosion-proof valve when connecting on the circular apron of lithium cell, be provided with the crescent explosion-proof hole with crescent explosion-proof valve crescent through-hole intercommunication on the circular base plate of circular apron, the top welding of crescent explosion-proof hole have the explosion-proof paster of crescent.
The invention has the advantages that:
the crescent explosion-proof valve is in a crescent annular plate structure, the inner hole of the crescent explosion-proof valve is a crescent through hole, the crescent through hole structure greatly increases the explosion-proof area, and the explosion-proof valve is high in safety and high in explosion point stability; the outer ring width from one end to the other end of the invention is always consistent, the inner ring width from one end to the other end of the invention is always consistent, when the crescent explosion-proof valve is arranged on the circular cover plate of the lithium battery, the crescent explosion-proof valve is in a symmetrical structure along the radial line of the circular cover plate, thus being convenient for installation; the positions of the two ends of the outer wall and the inner wall of the explosion-proof valve are both arc surface structures, so that the explosion-proof area is further increased, and the stability of the explosion point of the explosion-proof valve is improved.
