Abstract: A hinge includes a base frame unit and two rotatable axle units. The base frame unit includes a base seat and a protective cover. The base seat has two guideways having upper and lower segments, and two shaft sliding slots. The protective cover has a base wall and two pivot pins. Each axle unit rotatably extends through the base seat, and includes a hinge shaft rotatably extending through the shaft sliding slot, a first rotary member non-rotatably fitted to the hinge shaft, a second rotary member connected with the first rotary member, and a support bracket non-rotatably fitted to the hinge shaft. The first rotary member has a guide key slidably engaged in the guideway. The second rotary member is pivoted to the pivot pin and has an engaging hole for receiving the guide key.

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.

Abstract: A torque-variable single-shaft rotary shaft structure with multiple frictional pairs includes a pivot shaft. A first support is secured to a pivot shaft and a second support is disposed on the pivot shaft. An adjustment wheel assembly, a frictional assembly and an elastic assembly are fitted on the pivot shaft. The adjustment wheel assembly and the frictional assembly have a first adjustment wheel and a second frictional member synchronously movable with the first support and a second adjustment wheel and a first frictional member synchronously movable with the second support. When the first and second supports are rotated, the first and second adjustment wheels are driven to contact and abut against each other so as to provide axial action forces. The frictional assembly has multiple first and second frictional members, which are alternately arranged in frictional contact with each other to form multiple frictional pairs.

Abstract: A hinge module includes a joint assembly, a first pivot, and a second pivot. The joint assembly includes a first joint washer, a second joint washer separate from and coplanar with the first joint washer, an interlock member having two elongated limiting holes, and two pins. The first joint washer has a first pivot hole and a first pin hole. The second joint washer has a second pivot hole and a second pin hole. The pins are respectively inserted into the first and second pin holes and movably pass through the limiting holes. The first and second pivots respectively pass through the first and second pivot holes. When the first joint washer is rotated around the first pivot, the corresponding pin moves the interlock member in a direction perpendicular to each limiting hole, thereby moving the other pin to rotate the second joint washer around the second pivot.

Abstract: A bendable display apparatus includes a carrying plate, a bendable display, and two supporting devices. Each supporting device includes a dual-shaft hinge module and two buffering modules respectively arranged at two opposite sides of the dual-shaft hinge module. Each dual-shaft hinge module includes two shafts, a linking member clamped between the two shafts, and two side wing members respectively and slidably installed on the two shafts. The two buffering modules are respectively installed on the two shafts and are respectively cooperated with the two side wing members. Each buffering module includes an internal connecting member fixed on and synchronously rotatable with the corresponding shaft and an external connecting member slidably disposed on the internal connecting member and provided to be fixed on a carrying plate. Each side wing member has a limiting portion passing through the corresponding internal connecting member and the corresponding external connecting member.

Abstract: A torsion device is adjustable for providing a predetermined torsion curve, and includes two external connecting members and N numbers of torsion modules, in which 2≤N. Each torsion module includes a plurality of stacked torsion washers, an interlocking unit, and two shafts passing through the torsion washers and the interlocking unit. The two shafts of each torsion module are rotatable relative to each other in an angle range so as to generate a torsion curve, the N numbers of the torsion modules generate M kinds of torsion curves different from each other, and 2≤M≤N. The predetermined torsion curve is formed by adding at least two of the M kinds of the torsion curves, and at least two of the N numbers of the torsion modules corresponding to the predetermined torsion curve are fixed to the two external connecting members.
