specific Embodiment

[0019] Such as figure 1 As shown, the spring-based battery shockproof and shockproof mechanism of the present invention includes: a battery box 1 , a spring 2 , a cylindrical lithium-ion battery 3 , a heat-conducting glue 4 , a pressure relief valve 5 and a flame-retardant material 6 .

[0020] The cylindrical lithium-ion battery 3 is fixed in the battery box 1 through a thermally conductive glue 4, such as figure 1 shown. The upper and lower ends of the battery box 1 are equipped with a pressure relief valve 5, and the inside of the battery box 1 is coated with a flame retardant material 6. The cylindrical lithium-ion battery in this example is a 18650 nickel-cobalt-aluminum ternary lithium-ion battery. The spring is a steel spring with a thermal conductivity of 100W / (m·k). The size of the spring is designed to be 66cm in height and 18mm in inner diameter according to the size of the 18650 lithium-ion battery. The thermal conductivity of the thermally conductive adhesive i...

Abstract

The invention discloses a spring-based battery anti-vibration and anti-shock mechanism which is suitable for a cylindrical lithium ion battery and which has anti-vibration anti-shock and heat conduction effects. The mechanism consists of a spring and a battery box. The spring is made to comply with the size of the cylindrical lithium ion. The batteries are installed in the spring to realize the integration of the spring and the batteries. The batteries are separated by the spring, which has the function of shock absorption and shock prevention and keeps a sufficient cooling space.

Description

technical field [0001] The invention relates to a spring-based battery shockproof and shockproof mechanism, which belongs to the field of lithium ion battery safety, in particular to a shockproof and shockproof mechanism. Background technique [0002] Lithium-ion batteries are increasingly used in electric vehicles. As the sales of electric vehicles gradually increase, electric vehicle fire and explosion accidents caused by collision accidents gradually increase. The biggest difference between electric vehicles and fuel vehicles is the difference in power sources. The explosion and fire of lithium-ion batteries is the main reason for the complexity of electric vehicle accidents. [0003] The inevitable external mechanical abuse conditions can lead to the failure of internal components of Li-ion batteries, causing internal short circuits, which can lead to fires and even explosions. The use environment of electric vehicles is only for lithium-ion batteries, and its use cond...
