Button structure and energy storage device

Abstract

This application relates to the field of button technology and discloses a button structure and an energy storage device. The button structure is disposed on the housing of the energy storage device, and the housing has an assembly hole. The button structure includes a button, a sealing element, and a sealing ring. The button is installed in the assembly hole and partially protrudes from the housing. The sealing element includes a first body and a second body connected to the periphery of the first body. The second body is tightly connected to the surface of the housing, and the first body and the housing enclose a sealed space. The portion of the button protruding from the housing is located within the sealed space. The sealing ring surrounds the button and is located between the button and the housing. The sealing ring is squeezed between the button and the housing to seal. The button structure of this embodiment, disposed on the housing of the energy storage device, increases the difficulty of water seeping into the space between the button and the housing, improves the waterproof effect, and thus reduces problems such as button corrosion and functional failure.
