Abstract: A battery cover mechanism used in a portable electronic device includes a housing, a releasing assembly and a battery cover. The housing has an assembling surface, an accommodating portion disposed on the assembling surface and at least one latching slot disposed thereon. The battery cover defines a notch therethrough and comprises at least one latch disposed thereon corresponding to the latching slot of the housing for being detachably mounted on the housing. The releasing assembly is releasably assembled within the accommodating portion of the housing and partially accommodated within the notch of the battery cover to release the battery cover from the housing.

Abstract: A hinge assembly (100) includes a cam (13), a follower (14), a first spring (12), a control member (18) and a second spring (16). The cam has a cam surface. The follower has a latching cam surface engaging with the cam surface. The first spring provides an elastic force causing the cam surface of the cam and the latching cam surface of the follower to resist each other. The control member slidably resists the follower. The second spring provides an elastic force to return the control member. The control member is movable to push the follower to rotate to realize the cam surface of the cam to rotate relative to the latching cam surface of the follower.

Abstract: A battery cover latching mechanism is provided. The battery cover latching mechanism includes a housing, a cover member and a button assembly arranged on the housing. The button assembly includes a pressing member and an elastic member. The pressing member includes a locking block. The cover member includes a locking member. The locking block is detachably interlocked to the locking member. The elastic member is used to push the cover member away from the housing.
