Abstract: A hinge mechanism includes a plurality of linkage units, each including a base bar and two rotating assemblies pivotally connected with two carrying sections of the base bar. Each rotating assembly has a synchronous rotation bar, a friction plate and a torsion plate. The friction plate has a first major plate body and a friction increasing portion inclined outwardly from the major plate body. The rotating assemblies are turnable relative to the base bar between unfolded and folded positions. During the turning, the friction increasing portion is gradually overlapped upon and in frictional contact with the torsion plate so as to increase a friction force for providing a stable turning.

Abstract: A bendable displaying apparatus of the present disclosure includes two housings, a supporting device, and a bendable display. The supporting device is fastened to the two housings and is arranged between the two housings. The supporting device includes a retainer, two supporting units, a first supporting plate, and two second supporting plates. The bendable display is disposed on the two housings, the first supporting plate, and the two second supporting plates. When the two housings are moved to stack with each other, the two housings drive the two supporting units to move the two second supporting plates along a direction away from each other and drives the retainer to downwardly move the first supporting plate, so that the two second supporting plates and the first supporting plate jointly form a space that provides the bendable display to deform therein.

Abstract: A hinge includes two rotatable axle units disposed on a base seat and each having two rotatable hinge shafts, two movable bracket units each including a base plate, two rotary blocks non-rotatably sleeved on the hinge shafts, and two movable plates movable relative to the rotary blocks, and two synchronizing units for making synchronous rotations of the hinge shafts. Each synchronizing unit includes a first gear member having two end surfaces in form of bevel gears, and two second gear members each meshing with the respective end surface and fitted to the respective rotary block. Rotations of the hinge shafts at one side of the base seat result in rotations of the rotary blocks and the second gear members, and bring in rotations of the second gear members, the rotary blocks and the hinge shafts at the other side to make the synchronous rotations.

Abstract: A flexible electronic device includes a flexible display, a support mechanism for carrying the flexible display thereon, and two hinge mechanisms. Each of the hinge mechanisms is disposed between first and second substrate units and interconnects inboard end edges of the first and second substrate units of the support mechanism, and includes first and second linking units pivotable relative to a mounting assembly. With a first height between first outer and inner pivot axes of the first linking unit and a second height between second outer and inner pivot axes of the second linking unit, substrate seats can be moved away from inner support plates, and the inner support plates are movable downwardly to provide a leeway space for a bending part of the flexible display to be bendably received therein.

Abstract: A hinge mechanism connectable with two housing shells for a flexible display to be attached thereto includes a base seat, a torque transmitting unit and two rotary members. The base seat defines therein a rail region and two mounting regions. Each mounting region is defined by an arcuate bottom wall and first and second ribs. The torque transmitting unit includes two transmitting shafts and a synchronously driving member. The rotary members are disposed at the mounting regions to be pivoted about the transmitting shafts so as to bring the housing shells into unfolded and folded states.

Abstract: A hinge includes two rotatable axle units each having two hinge shafts, two synchronizing units each disposed to make synchronous rotations of the hinge shafts, two movable bracket units each having a turnable base plate, two rotary blocks non-rotatably sleeved on the hinge shafts, and two movable plates movable relative to the rotary blocks, and two guiding bracket units, each having male and female arms respectively connected with two movable plates, and a plurality of guiding connecting members interposed between the arms. Each guiding connecting member has a protrusion and a sliding groove, and is angularly movable with the rotations of the hinge shafts. Removal of the protrusion from the sliding groove of an adjacent guiding connecting member is prevented by means of engagement of an abutting portion of the protrusion with an abutted block in the groove.

Abstract: An electronic device includes a base cover, a cover plate which is slidable relative to the base cover among a closed position, an open position, and a transition position, and a slide positioning mechanism which is configured for positioning the cover plate relative to the base cover, and which has first and second magnetically attractive units. When the cover plate is in a selected one of the closed and open positions, a magnetically attractive force is generated to position the cover plate in the selected one of the closed and open positions. When the cover plate is in the transition position, a magnetically repulsive force is generated to facilitate movement of the cover plate away from the transition position.

Abstract: A multi-linkage hinge includes a base bar, two friction bars, two synchronous rotation bars and two torsion plates. The base bar extends longitudinally to have two connecting ends and two middle pivot portions . Each friction bar has two link ends respectively coupled to the connecting end of the base bar and a middle portion of the respective torsion plate. The synchronous rotation bars are interposed between the friction bars, and each has two pivot ends respectively coupled to the middle pivot portion of the base bar and a driven end of the respective torsion plate. The torsion plates are turnable synchronously relative to the base bar between unfolded and folded positions. In the unfolded position, a bending space is formed between the torsion plates for receiving a bending portion of the display sheet.
