Abstract: An electronic device (100) using a cover mechanism (30) to cover its hole (14) of its housing (10) is described. The cover mechanism includes a cover (20) and a locking structure (11). The cover has a latching portion (23) and a locking portion (21), both of which include a resilient part. The locking structure is configured for associating with the locking portion and the latching portion. Thus, the cover is latched to the housing to cover the hole by deforming the resilient parts. After the cover is unlatched from the housing by a sudden pulling force, the locking portion still physically connects to the locking structure. After the cover is unlatched from the housing by a normal pulling force, the locking portion has no physically relationship with the locking structure.

Abstract: An electronic device using a cover mechanism to cover a hole is described. The cover mechanism includes a base member, a cover member and a retaining member. The cover member is fixed with the retaining member and moves between a closed position and an opened position. In the closed position, the cover member is elastically, partially deformed to lock to the base member. In the opened position, the cover member can be elastically bent to expose the hole while still being physically attached to the base member.
