Abstract: A flexible electronic device includes a flexible display, a support structure and two hinge mechanisms. Each hinge mechanism includes a cam and first and second arm units. With the hinge mechanism having first and second cam follower protrusions of the first and second arm units which are moved from respective cavities of the cam and slide on respective peripheral cam surface sections of the cam during the pivoting of the first and second movable arms from an unfolded position to a folded position, a leeway is provided between the first and second movable arms for the flexible display to be bendably received therein.

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 hinge includes a stationary seat and two rotating units. Each rotating unit includes a linkage module that has an extension body that has a arcuate slide rail, a rotating bracket module that is rotatable and that has a fixing pin, and a sliding module that includes a connecting frame, a positioning pin, and a linkage member. The connecting frame has a curved groove that engages the arcuate slide rail such that movement of the rotating units between an opened and a closed state results in movement between the arcuate slide rail and the curved groove. The linkage member has a through hole, and an elongated slot which the fixing pin passes through to connect the rotating bracket module such that movement of the rotating units between the opened and closed states results in movement between the fixing pin and the elongated slot.

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: A hinge includes a fixed seat, and two symmetrically-disposed support modules that are convertible between an unfolded state and a folded state. Each of the support modules includes a sliding pivot arm that is slidable and pivotable with respect to the fixed seat, a pivot guide unit that is movably engaged with the sliding pivot arm, and a slide block that has a slide slot movably engaged with the sliding pivot arm, and an oblique sliding portion movably engaged with the pivot guide unit, such that the slide block is slidable with respect to the sliding pivot arm and the pivot guide unit when the support modules are converted between the unfolded state and the folded state.

Abstract: A hinge includes two brackets and a sliding module. Each bracket has a support shaft and a support plate for supporting a flexible display. The sliding module includes a rail seat, two rail keys, two axle keys and two auxiliary extending frames. The rail seat has two arcuate inboard rails, two receiving slots and two arcuate outboard rails. Each rail key has a key body received in the receiving slot, a sliding protrusion slidable along the arcuate inboard rail, and an arcuate key rail opposite to the sliding protrusion. The axle keys are slidable along the arcuate key rails, and are journalled on the support shafts. The auxiliary extending frames are slidable along the arcuate outboard rails and slidably connected with the support plates. With adjustment of the rails, moving paths of the keys are adjusted to meet the requirement of bending of the flexible display.

Abstract: A hinge includes: a base seat; two slide seats that are mounted on the base seat, that are movable between an inner position and an outer position, and that each have a slide rail portion; two rotary members that each have a slide portion being in sliding contact with the slide rail portion of a respective slide seat, and that are respectively rotatable relative to the slide seats; and two coupling mechanisms that are connected between the rotary members and the slide seats, such that rotations of the rotary members drive the slide seats to move between the inner position and the outer position. A distance between the slide seats decreases when the slide seats move from the outer position to the inner position.

Abstract: A hinge is mountable on a flexible display unit including a housing shell unit and a display unit. The hinge includes a base seat, a torsion module disposed above the base seat and secured to the display unit, and a bracket module disposed below the base seat. The torsion module includes two outer supporting units and an inner supporting unit at two ends and a middle of the base seat. The bracket module has two brackets securely connected to two support plates of the display unit and rotatable relative to the base seat. The hinge is rotatable between an unfolded position where the brackets are in an unfolded state, and an outfolding position where the brackets are close to and face each other. The outer and inner supporting units cooperatively define a semicircular-shaped supporting surface in the outfolding position for supporting the display unit.

Abstract: A hinge mechanism includes first and second inner guiding members secured on a base seat, and first and second movable members slidable engaged with the first and second inner guiding members and connected with first and second substrate units. During the movement of the movable members to an upright folded state, inboard end edges of the substrate units are moved away from each other to provide a bending space therebetween for a flexible display attached to the substrate units to be bendably received therein.
