Explosion-proof equipment of lithium battery

Abstract

The invention relates to the technical field of explosion-proof devices and in particular to explosion-proof equipment of a lithium battery. The explosion-proof equipment comprises a housing. An anode conducting strip is arranged on one side, close to the housing, of a cap body; corner plates are arranged on four corners of the inner wall of the housing; an explosion-proof plate is arranged between every two corner plates; locking boards are connected to one sides, far from the housing, of the explosion-proof plates through a plurality of damping springs; the corner plates and the explosion-proof plates are connected through connecting devices; a fixed clamp plate is arranged on one side of the housing; a notch is formed in the middle of one side, far from a hinge, of the fixed clamp plate; a clamping slot is formed in the middle of the fixed plate; one side, far from the hinge, of the cap body, is connected to a movable locking bar matched with the clamping slot through a pin roll; and a hammer-shaped head is arranged on the lower end of the moving locking bar. Compared with the prior art, the explosion-proof equipment provided by the invention is simple in structure, good in explosion-proofness, high in usability, practical and safer and small in potential safety hazard, brings more beneficial effects, and can avoid fire influence caused by explosion.

Description

technical field [0001] The invention relates to the technical field of explosion-proof devices, in particular to an explosion-proof device for lithium batteries. Background technique [0002] Today, with the rapid development of science and technology, electric vehicles are no longer a dream, and have been completely presented in front of the world. However, due to the high operating power of electric vehicles, the requirements for power and energy of power batteries are also extremely strict. . Due to the repeated charging and discharging of the battery during operation, a lot of heat will be generated, so in order to solve the heat dissipation problem of the battery, generally speaking, the battery box has a structure with multiple air ducts and multiple heat dissipation holes, but this design will bring many dark consequences. , when the battery is in an extreme working environment due to short circuit and other phenomena, it will easily come into contact with oxygen or ...
