Abstract: An alignment guiding sleeve for quick coupler includes a guiding sleeve having a closed engaging end provided with an engaging bore and an open guiding end defining a guiding bore and formed into a beveled guiding surface, and internally defining a guiding passage extending between and communicable with the engaging end and the guiding end. A male coupler can be assembled to the guiding sleeve by inserting through the engaging bore. The beveled guiding surface is adapted to guide a female couple into the guiding passage to connect to the male coupler. With the beveled guiding surface, any radial offset between the female coupler and the male coupler can be corrected, so that the female and the male coupler can be eventually aligned axially to connect together end to end without causing wear and incomplete watertight connection at the joint of the female and male couplers to result in leakage.

Abstract: A hinge includes two guide frames spaced apart from each other in a front-rear direction, a transmitting assembly interposed between the guide frames, a frictional torque generating assembly having two opposite thrust plates, and two rotary brackets disposed opposite to each other. Each rotary bracket includes an arcuate pivot portion pivotably connected with the respective guide frame, an actuating portion coupled with the transmitting assembly to actuate the transmitting assembly, and a frictional surface in frictional contact with the respective thrust plate to bring synchronous rotations of the arcuate pivot portion, the actuating portion and the frictional surface, and to make synchronous and opposite rotations of the rotary brackets.

Abstract: A foldable display device includes a hinge, a housing shell unit and a display unit. The housing shell unit includes two housing shells connected with left and right sides of the hinge, two support plates respectively disposed on the housing shells, and a plurality of pairs of display rails defined between the housing shells and the support plates. Each housing shell has a base shell wall connected with the hinge. Each display rail has a rail groove. The display unit is securely disposed to the hinge, and is movably engaged in the rail grooves. The hinge is rotatable between an unfolded position and an outfolding position. During rotation of the hinge, the display unit is moved along the rail grooves.

Abstract: A hinge includes a rotating shaft, two pivoting parts, and a seat. The rotating shaft includes a friction section and a protruding section coaxially extending from the friction section. Each of the pivoting parts includes a connecting piece and a sleeve piece. Each sleeve piece is extended from an edge side of the corresponding connecting piece, and bent and wrapped to form a sleeve hole. Each sleeve piece is configured to be sleeved on the friction section, and the two sleeve pieces on the peripheral surface of the friction section are bent and wrapped in different directions respectively. The seat includes a shaft hole. The friction section and the sleeve pieces are jointly arranged in the shaft hole, the connecting piece is fixed on the seat, and the protruding section protrudes out of the seat.

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 double-screen rotary shaft structure includes two synchronous spiral channels disposed on the link shafts. Asynchronous assembly is slidably pivotally fitted on the two link shafts. Two bosses are disposed on the synchronous assembly and respectively inlaid in the spiral channels of the link shafts. Two connection members are respectively securely connected with the two link shafts. Two link assemblies are respectively pivotally fitted on the link shafts to synchronously move with the synchronous assembly. Two slide members are attached to lower sides of the connection members and formed with oblique slots. A guide slide connection member is disposed in each oblique slot and connected with the link assembly. The middle sections of two links are pivotally disposed on the connection members. Each link has a driving end pivotally connected with the link assembly and a driven end to drive the slide member.

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: An outward-folding display device includes a casing unit and a display protection module. The casing unit includes first and second casings and a sliding board slidably mounted to the second casing. The second casing has a plurality of buffer slots. The display protection module is mounted in the second casing, and includes a plurality of buffer blocks and a plurality of resilient members. The buffer blocks slidably and respectively engage the buffer slots, and are connected to the sliding board. The resilient members are connected between the second casing and the sliding board for biasing the sliding board toward its default position when the buffer blocks are moved in a folding process of the outward-folding display device.

Abstract: An outward-folding display device includes two flat casings adapted to be connected to a flexible display, and two hinge units connected between the casings such that the casings are convertible between unfolded and folded positions. Each of the hinge units includes two rotatable drive shafts, and two compensation subunits each including a rotating plate that is co-rotatably connected to a respective one of the drive shafts, and a driven plate that is slidable relative to the rotating plate and that is connected to a respective one of the casings, such that during conversion of the casings, the driven plate and the respective one of the casings slide relative to the rotating plate to prevent the flexible display from being stretched and damaged.
