Abstract

The present disclosure provides a disassembly mechanism, a disassembly system of a power battery pack with the disassembly mechanism and a disassembly method of the power battery pack. The above disassembly mechanism includes a die base assembly, a pressing assembly and a removal tool assembly. The pressing assembly is movably connected to the die base assembly, and is used to abut against and press a single battery of a power battery pack. The removal tool assembly is slidably connected to the die base assembly and elastically connected to the die base assembly. The removal tool assembly is used to squeeze and separate a casing and the single battery of the power battery pack. The above disassembly mechanism can realize automatic disassembly of the power battery pack with few manual intervention, and solves the problem of low efficiency in the recycling and disassembly process of the power battery pack.

First claim
