Patent ID: 8195259

Claim:
An electronic device, comprising: a main body including a first planar surface; a battery receptacle in the first planar surface of the main body; a battery cover comprising a second planar surface, at least one locking portion and covering the battery receptacle, the first and second planar surfaces being parallel to each other at all times; and a resilient member including a first connecting portion and a second connecting portion non-coaxially positioned relative each other, the first connecting portion rotatable and directly connecting with the main body, and the second connecting portion directly connecting with the battery cover; wherein when the second surface of the battery cover covers the battery receptacle, the resilient member is deformed and generates a resilient force which pushes the battery cover to make the at least one locking portion of the battery cover lock to the main body, when the battery cover is rotated on the main body along the first connecting portion of the resilient member, the second surface offsets relative to the first surface to expose the battery receptacle.
