Description

Technical Field

[0001] The utility model belongs to the technical field of battery compartments, and in particular relates to an explosion-proof combined battery compartment. Background Art

[0002] The battery compartment structures widely used in the market are relatively simple. Basically, they are made by directly welding the battery pack inside the shell and then simply fixing it. Once a battery cell inside catches fire and explodes, other batteries will be damaged together, causing greater explosion hazards. Since the existing battery packs are welded tightly, once an explosion occurs, the single battery shell will be damaged by the strong impact force and high temperature. The energy of the explosion will rush out from the positive seal of the battery. The rushing energy will cause high-temperature damage to the positive seals of other batteries in the sealed space, causing the risk of chain combustion and explosion, causing personal and property damage. As the usage increases, the harm becomes more obvious. Therefore, it is necessary to design a battery compartment with explosion-proof function and safe and reasonable structure to solve the above problems. Utility Model Content
