  • Slidable battery door assembly
    Patent number: 9324979
    Abstract: A slidable battery door assembly is described. In implementations, the slidable battery door assembly (hereinafter “door assembly”) includes a door that is slidable to control access to a battery compartment for a device. Also included is a battery contact inside the battery compartment that is coupled to the door. When the door is closed, the battery contact holds a battery in place and serves as a portion of an electrical circuit that includes the battery. The door may be slidably opened such that the battery contact releases the battery, allowing the battery to be removed from the battery compartment. Thus, the door assembly enables easy installation and removal of a battery. Further, the door assembly can be positioned to hold a battery securely in place and provide an electrically conductive connection between the battery and an electrical circuit.
