Lithium ion battery module

Abstract

The invention discloses a lithium ion battery module and belongs to the technical field of batteries. The lithium ion battery module comprises an explosion-proof box, a damping mechanism is arranged on the inner lower surface of the explosion-proof box, a battery body is arranged on the upper surface of the damping mechanism, a window is arranged on the inner back surface of the explosion-proof box, a smoke removing and fire extinguishing mechanism is arranged in the window, and plugging mechanisms are arranged on two inner side walls of the explosion-proof box; the smoke removing and fire extinguishing mechanism comprises a motor, a rotating rod, a negative pressure blade, a first belt pulley, a second belt pulley, a reciprocating screw rod, a first sliding rod, a moving block, an automatic fire extinguisher, a one-way valve, an exhaust pipe and a gas storage box, wherein the motor is fixedly connected to the interior of the window, the rotating rod is fixedly connected to the output end of the motor, the negative pressure blade and the first belt pulley are fixedly connected to the circumferential surface of the rotating rod, and the reciprocating screw rod is movably connected with the inner surface of the explosion-proof box. According to the lithium ion battery module, poison gas can be conveniently sucked into the gas storage box, so that leakage of the poison gas can be prevented; and the automatic fire extinguisher can be driven to move to conduct fire extinguishing operation.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a lithium ion battery module. Background technique [0002] Lithium-based batteries are divided into lithium batteries and lithium metal batteries. Lithium-ion batteries are used in mobile phones and laptops, commonly known as lithium batteries. Lithium-ion batteries generally use materials containing lithium elements as electrodes, which are representatives of modern high-performance batteries. [0003] However, when the current lithium-ion battery is damaged and a fire occurs, the toxic gas produced is easy to spread to the outside of the environment to cause air pollution, and it is inconvenient to quickly extinguish the lithium battery components, resulting in significant economic losses. Contents of the invention [0004] The purpose of the present invention is to provide a lithium-ion battery module to solve the problems raised in the above-mentioned background techno...
