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 foldable electronic apparatus includes a flexible display, a housing unit, and a supporting device. The supporting device includes a flexible first supporting plate, a flexible second supporting plate, and a plurality of supporting members. Each of the supporting members has a first end portion that is connected to the first supporting plate, a second end portion that is connected to the second supporting plate, and a main body portion that has two opposite sides respectively connected to the first end portion and the second end portion. The supporting device is operable to convert between a first state, in which two opposite sides of the supporting device are distal from each other, and a second state, in which the supporting device is folded along a folding axis such that the opposite sides of the supporting device are proximate to each other.

Abstract: A sliding rail device includes a first rail, a second rail and two supporting units. The first rail includes a first base wall and two first side walls cooperating with the first base wall to define a first passage. The first base wall has two engaging slots respectively adjacent to the first side walls. The second rail engages the first passage, is movable relative to the first rail, and includes a second base wall and two second side walls. The supporting units respectively and movably engage the engaging slots, and respectively and slidably abut against the first side walls and the second side walls. During movement of the second rail relative to the first rail, the supporting units are driven to respectively move along the engaging slots, and to move toward each other to tighten abutment of the supporting units against the second side walls.

Abstract: A hinge connectable with two housing parts to allow opening and closing thereof includes a mounting seat, two rotary units and two lateral support plates. The mounting seat has two first arcuate slots at two sides of a central line. The rotary units are connected with the mounting seat at the two sides of the central line for mounting the housing parts, and shiftable between an unfolded state and a folded state. Each rotary unit includes a linking member, a rail sliding block, a rotating bracket and an interposed sliding member interposed between the rail sliding block and the rotating bracket. The sliding of the rail sliding block relative to the rotating bracket can be steady and firm without the need to elongate the inclined rails of the rail sliding block and the rotating bracket, which renders the hinge more compact and slim.

Abstract: A hinge includes a first fixing bracket, a shaft and a swivel bracket. The first fixing bracket includes two first support pieces and a first connection piece. The two first support pieces are arranged in parallel to each other, and the first connection piece is connected to the two second support pieces. The two first support pieces are respectively provided with a shaft hole and the shaft holes are arranged coaxially along a central axis. At least one of the first support pieces is provided with one limiting extension portion extending in a direction in parallel to the central axis at an upper front end of the first support piece and extending towards the other first support piece. The shaft is inserted into the shaft hole. The swivel bracket includes a mounting plate; an extension plate extending from a bottom edge of the mounting plate and bent towards a side corresponding to the inner surface of the mounting plate; at least one sleeve piece located between the two first support pieces, extending from an end of the extension plate away from the bottom edge, and bent and wound towards the side corresponding to the inner surface. The sleeve piece is configured to be sleeved over the shaft, such that the swivel bracket can rotate with respect to the first fixing bracket. When the swivel bracket is flipped outwards with respect to the first fixing bracket, the extension plate moves towards the limiting extension portion.
