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.

Abstract: An angularly positionable flexible display device includes a flexible display, a first substrate, a second substrate, and a positionable hinge mechanism which is disposed in a mounting space defined between the first and second substrates. In response to application of a manual force upon at least one of the first and second substrates, the first substrate is angularly displaceable relative to the second substrate through the positionable hinge mechanism to permit the flexible display to be bent with the angular displacement of the first and second substrates. Once the manual force is release, the first substrate is angularly positioned relative to the second substrate through frictional force provided by the positionable hinge mechanism.

Abstract: A rotation device includes a base seat, an axle unit, a lower rotating module and an upper rotating module. The axle unit includes an upper axle and a lower axle. The lower rotating module includes a lock unit, and an outer barrel that is disposed in the base seat and that is penetrated by the lower axle. The lock unit includes a lock plate that is sleeved on the lower axle, and a lock member that is mounted to the base seat. The lock plate is formed with a first lock groove. The lock member has a lock portion that is operable to move into the first lock groove. The upper rotating module is disposed in the base seat and is co-rotatably sleeved on the upper axle. The upper rotating module is able to be driven by the upper axle to rotate relative to the lower rotating module.

Abstract: A hinge includes a base seat, two connecting members and two sliding members. The base seat has two first arcuate rails each extending around a first rotating axis. Each connecting member has a first sliding portion matingly engaged with and slidable along the respective first arcuate rail, and a second arcuate rail extending around a second rotating axis. Each sliding member has a second sliding portion matingly engaged with and slidable along the second arcuate rail such that the two sliding members are rotatable relative to the base seat between an initial position and a terminal position about the first rotating axes and about the second rotating axes.

Abstract: A multi-position hinge includes a base seat, a first axle, a second axle and a sliding assembly. The first and second axles rotatably extend through the base seat in a first direction and are spaced apart from each other in a second direction. The first axle has a first recess, a second recess and a first gear portion. The second axle has a third recess, a fourth recess and a second gear portion corresponding with the first recess, the second recess and the first gear portion, respectively. The sliding assembly includes a first sliding member engageable with the first and third recesses, and a second sliding member engageable with the second and fourth recesses. The first and second axles are rotatable in turn and then rotated synchronously to perform multi-position shifting.

Abstract: A hinge is mountable between two casing parts of a flexible electronic device, and includes a base seat and two rotating modules disposed at two sides of the base seat for respectively mounting the casing parts thereon. Each rotating module includes a primary support plate pivotably connected to the base seat, and a secondary support plate pivotably connected to the primary support plate. When the rotating modules are rotated from an initial position, where the secondary support plates are flush with the primary support plates for resting and supporting a flexible display thereon, to a terminal position, where the secondary support plates are turned away to provide a leeway, the casing parts are shifted from an unfolded state to a folded state.
