Abstract

This utility model relates to the field of battery fire protection, specifically an external fireproof structure for batteries. It includes a cylindrical protective box with a fan that supports the battery installation, and an anti-collision and fireproof structure arranged around the protective box, using elastic buffer blocks and connecting rods, etc., to provide relatively reliable pressure relief and buffering effects for the protective box and battery. The advantages of this utility model compared to existing technologies are: firstly, the device provides the battery with a protective box equipped with a cooling fan and ventilation openings, ensuring it operates in a controlled, relatively low-temperature environment to prevent self-heating and combustion; secondly, multiple baffles carrying elastic buffer blocks are arranged at sufficient distances to surround the outside of the protective box, providing impact protection.
