Abstract: A foldable cabinet framework includes two side frames, a first beam body, and a second beam body, where two opposite ends of each of the first and second beam bodies are respectively connected to the two side frames. The first beam body and the second beam body each include a hinged part, and when the first beam body and the second beam body are in a straight state, the first beam body and the second beam body are supported between the two side frames, so that the two side frames are spaced apart and symmetrically disposed. The first beam body and the second beam body enclose a framework of a three-dimensional structure. The first beam body and the second beam body are folded by using the hinged part; and after the first beam body and the second beam body are folded, the two side frames are superposed with each other.

Abstract: The energy storage module of the battery pack is located in the housing, the heat insulation panel is located between the energy storage module and the housing, the heat insulation panel includes a heat insulation layer and an outer packaging layer. The outer packaging layer wraps the outside of the heat insulation layer and compresses a thickness of the elastic heat, insulation layer, and a ventilation channel is formed between the heat insulation panel and the energy storage module. The outer packaging layer is configured to release compression of the elastic heat insulation layer when the energy storage module reaches a thermal runaway temperature, and the heat insulation panel is filled between the housing and the energy storage module, thereby slowing down a speed at which heat passes through a side panel and spreads to the outside of the battery pack along the ventilation channel.
