END COVER ASSEMBLY, ENERGY-STORAGE DEVICE, AND ELECTRICITY-CONSUMPTION DEVICE

An end cover assembly, an energy-storage device, and an electricity-consumption device are disclosed in the present disclosure. The end cover assembly includes a top cover, an explosion-proof valve, and a protective sheet. The top cover has a first mounting surface and a second mounting surface. The top cover defines a first mounting recess, an explosion- proof hole, and a vent recess, where the first mounting recess is recessed from the first mounting surface, and the vent recess is in communication with the explosion-proof hole. The explosion-proof valve is attached to the second mounting surface and covers an opening of the explosion-proof hole positioned on the second mounting surface. The protective sheet is attached to the bottom wall of the first mounting recess and covers an opening of the explosion-proof hole positioned on the bottom wall of the first mounting recess and the other part of the vent recess.
