Abstract
A doorbell device includes a housing, a passive element, a battery module, and a thermal expansion element. The housing includes a mounting plate, and the mounting plate includes a through hole, an inner surface, and an outer surface. The passive element is movably disposed in the housing. The passive element includes a first side surface and a second side surface. The first side surface faces the mounting plate. The battery module is disposed on the first side surface and corresponds to the through hole. The thermal expansion element is disposed between the second side surface and the housing. The passive element allows a gap to be maintained between the battery module and the outer surface, or is driven, by the thermal expansion element, to allow at least a part of the battery module to be located in the through hole and at the same plane with the outer surface.
