Hinge mechanism for foldable electronic apparatus

摘要

A housing of an electronic apparatus including a flip-cover opening/closing device which includes: rotation portions positioned in an outward direction of the housing, the rotation portions being detached from the housing upon rotating a flip-cover over a communication angle and applying a force; a pair of necks for converting a rotational movement of the flip-cover into a rectilinear movement upon rotation of the flip-cover over the communication angle, so as to detach a hooking socket of the flip-cover from a hinge shaft of the housing; and at least one tension opening for absorbing the force applied to the hooking socket of the flip-cover upon the detachment of the hooking socket; the flip-cover being detachable from the housing. The rotation portions may include a space disposed therebetween for reducing the force on the hooking groove caused when detaching the rotation portions from the hooking socket. At least one supportable rib may be provided between the rotation portions and the hooking socket for preventing variation of the hooking socket caused upon detaching the flip-cover.
