Lithium battery high-temperature protection structure

Abstract

The invention discloses a lithium battery high-temperature protection structure, and belongs to the technical field of lithium battery protection. The structure comprises a shell, a storage bin, an objective table and a stop block; the storage bin is arranged in the shell, the objective table is arranged in the storage bin, the stop block is fixedly connected to the inner wall of the storage bin,the side surface of the stop block is fixedly connected with an electric push rod, and the left end of the electric push rod is fixedly connected with a rack; the lower surface of the rack is fixedlyconnected with a first slider; by arranging an electric push rod, a rack and a gear, when a temperature sensor senses that the temperature of a storage bin is too high, an instruction is sent to a control switch, the electric push rod is controlled to operate to drive the rack to move rightwards, and under cooperation of the rack and the gear, a first rotating shaft rotates anticlockwise to drivea first connecting rod to rotate anticlockwise; under the cooperation of the first connecting rod and the second connecting rod, the objective table loaded with the lithium battery descends, the electrode end of the lithium battery is separated from the electrode butt joint port, power supply is stopped, and thermal runaway of the lithium battery caused by continuous power supply is avoided.

Description

technical field [0001] The invention relates to the technical field of lithium battery protection, more specifically, it relates to a lithium battery high temperature protection structure. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. With the rapid development of the new energy vehicle market, lithium batteries have been widely used, and their safety problems have become increasingly prominent. New energy vehicles caught fire Accidents happen from time to time. Most of the fires of new energy vehicles are caused by the thermal runaway of lithium batteries. The existing devices cannot directly cut off the power of lithium batteries, so that people can continue to use them. It is easy to cause damage to lithium batteries, and it is easy to cause fires in severe cases. . Contents of the invention [0003] In view of the deficiencies in ...
