END COVER ASSEMBLY, ENERGY STORAGE APPARATUS, AND ELECTRIC DEVICE

The present disclosure provides an end cover assembly, an energy storage apparatus, and an electric device. The end cover assembly includes a top cover, an explosion-proof sheet, and a shielding member. The top cover has a first surface and a second surface facing away from the first surface. The top cover further has an explosion-proof hole through the first surface and the second surface. The explosion-proof sheet is configured to seal the explosion-proof hole and is connected to the top cover. The shielding member is located at a side of the explosion-proof sheet close to the second surface and is connected to the top cover. The top cover, the explosion-proof sheet, and the shielding member form a chamber. The shielding member has a first air vent in communication with the chamber. When the end cover assembly is applied in the energy storage apparatus, the first air vent is also in communication with a space where the electrode assembly is located. When the end cover assembly of the present disclosure is applied in the energy storage apparatus and the energy storage apparatus is impacted or drops, an electrolyte can be prevented from directly impacting the explosion-proof sheet, thereby preventing the explosion-proof sheet from being accidentally triggered in advance and preventing explosion.
