Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of folding fire cover, especially to a foldable mobile fire cover. BACKGROUND

[0002] With the continuous growth of global energy demand, traditional fossil energy resources are gradually decreasing, and energy supply is tight. New energy has the characteristics of being clean and low-carbon, which can significantly reduce greenhouse gas emissions and slow down global climate deterioration. At the same time, the promotion and application of new energy can help reduce air, water, soil and other environmental pollution, and improve the ecological environment.

[0003] New energy electric vehicles mainly include two-wheeled electric vehicles and four-wheeled electric vehicles. Although electric vehicles meet the requirements of energy saving and environmental protection, new energy batteries such as ternary lithium batteries, sodium batteries and phosphate iron lithium batteries have the characteristics of chemical activity and flammability. When they encounter impact, overload, improper use or aging, they are prone to explosion. If the fire cannot be extinguished in time, it will cause damage to surrounding vehicles and personnel.

[0004] Most of the current electric vehicle fire extinguishing methods use fire extinguishers, fire water, foam and other methods. Due to the burning characteristics of new energy batteries, these fire extinguishing methods are time-consuming and laborious but ineffective. The final result is that the car is destroyed. Sometimes the fire is difficult to extinguish, and the burning will spread to the surrounding objects, causing secondary losses. UTILITY MODEL CONTENTS
