Abstract: A hinge is connectable with two housing shells for permitting relative folding and unfolding of the housing shells, and includes a fixed seat, at least two rotating units, two lateral support plates and at least one synchronous driving unit. The rotating units are shiftable between an open state and a closed state. Each rotating unit includes a linking member fittingly and arcuately slidable on the fixed seat, a sliding member fittingly and arcuately slidable on the linking member, and a rotary bracket pivotably mounted on the fixed seat and inclinedly slidable on the sliding member. The lateral support plates are respectively mounted on the linking members. The synchronous driving unit includes two inboard pinions and two outboard pinions arranged laterally to mesh with bracket toothed portions of the rotary brackets to make synchronous rotation of the rotary brackets in opposite rotational directions.

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 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 connectable with two housing parts to allow opening and closing of the housing parts. The hinge includes a mounting seat and two rotary units. The mounting seat has a central recessed portion. The rotary units are connected with the mounting seat and shiftable between an unfolded state and a folded state. Each rotary units includes a linking member, a rail sliding block, a rotating bracket and a cover plate. During the shifting from the unfolded state to the folded state, the rail sliding block is slid relative to both the linking member and the rotating bracket and is turned relative to the mounting seat. In the folded state, the cover plates are inclined to each other in a direction away from the mounting seat to cooperate with the central recessed portion to form a space for receiving a bending portion of a flexible display.
