Abstract: A battery cover latch mechanism is configured for detachably assembling a battery cover on a housing. The battery cover latch mechanism includes a button, an assembly portion including two blocks positioned on the housing, a latching part positioned on the battery cover; and a resilient member secured on the button and latching to the blocks to provide a resilient force to the button. The button releasably latches to the latching part to lock the battery cover to the housing or release the battery cover from the housing. The invention also discloses a portable electronic device using the battery cover latch mechanism.

Abstract: A battery cover latching structure (30) attached to a battery cover (20) of a portable electronic device (100), which comprises a fixing section (32) and a latching section (34). The fixing section (32) is used to attach the latching structure (30) to the battery cover (20). The latching section (34) extends from the fixing section (32) and has a surface (3422) facing the battery cover (20). The latching section (34) has a block (3424) protruding from the surface (3422) and configured for contacting the battery cover (20).
