Abstract

The invention discloses a lithium battery protection device which comprises a protection box, a chuck, a partition plate, a radiator and a fan. A baffle is arranged at the top of the protection box. The baffle is connected with a first spring, and the first spring is connected with the chuck. A lithium battery is arranged in the protection box. The side wall of the lithium battery clings to the partition plate, and the partition plate is connected with a second spring. The side wall of the protection box is connected with the radiator, and the bottom of the radiator is connected with the fan.A rotating shaft is arranged in the fan and is connected with fan blades. Ventilation holes are formed in the bottoms of the fan blades. A flat plate layer is arranged at the bottom end of the protection box. The bottom of the flat plate layer is connected with a heat insulation layer, and the bottom of the heat insulation layer is connected with an anti-seismic layer. The chuck structure and thepartition plate structure of the battery protection device well play a role in fixing the lithium battery; heat emitted by the lithium battery can be pumped out from the ventilation holes through thefan and then emitted through the radiator; the heat insulation layer can play a role in heat preservation when the temperature is low; and the anti-seismic layer plays a good anti-seismic role.

Description

technical field [0001] The invention relates to a battery protection device, in particular to a lithium battery protection device, and belongs to the technical field of protection device applications. Background technique [0002] The battery protection device is mainly used for the protection of the battery. A lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing and storage of lithium metal , use, the environmental requirements are very high. [0003] The currently used battery protection device has defects such as poor effect of fixing the battery, poor heat dissipation effect, poor shock resistance, reduced service life of the battery, insufficient structure and lack of functions. Therefore, a lithium battery protection device is proposed aiming at the above problems. Contents of the invention [0...
