Abstract: A multi-link hinge assembly includes a link rod unit including a base rod, two supporting link rods, two synchronization link rods, two supporting rods, and a supporting plate unit. The base rod has a base rod body, two base connecting portions respectively connected to opposite ends of the base rod body, and two central connecting portions disposed between the base connecting portions. Each synchronization link rod has a first synchronization end portion pivotably connected to a respective one of the central connecting portions, and a second synchronization end portion opposite thereto. The supporting plate unit includes two supporting plates respectively connected to the supporting rods and each having inner and outer portions. The link rod unit is operable between an unfolded position and a folded position, where the second synchronization end portions are away from each other, and the inner portions define a relief space therebetween.

Abstract: A monitor support device includes a base support and first and second supports mounted to the base support. The first support includes a first connecting body rotatable about a first rotational axis, and a first mounting body adapted to be mounted with a first monitor and rotatable relative to said first connecting body about a second rotational axis. The second support includes a second connecting body rotatable about the first rotational axis, and a second mounting body adapted to be mounted with a second monitor and rotatable relative to said second connecting body about a third rotational axis. The second and third rotational axes each defines an 45° angle with the first rotational axis.

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 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 mechanism includes a plurality of linkage units, each including a base bar and two rotating assemblies pivotally connected with two carrying sections of the base bar. Each rotating assembly has a synchronous rotation bar, a friction plate and a torsion plate. The friction plate has a first major plate body and a friction increasing portion inclined outwardly from the major plate body. The rotating assemblies are turnable relative to the base bar between unfolded and folded positions. During the turning, the friction increasing portion is gradually overlapped upon and in frictional contact with the torsion plate so as to increase a friction force for providing a stable turning.

Abstract: A bendable displaying apparatus of the present disclosure includes two housings, a supporting device, and a bendable display. The supporting device is fastened to the two housings and is arranged between the two housings. The supporting device includes a retainer, two supporting units, a first supporting plate, and two second supporting plates. The bendable display is disposed on the two housings, the first supporting plate, and the two second supporting plates. When the two housings are moved to stack with each other, the two housings drive the two supporting units to move the two second supporting plates along a direction away from each other and drives the retainer to downwardly move the first supporting plate, so that the two second supporting plates and the first supporting plate jointly form a space that provides the bendable display to deform therein.

Abstract: A hinge includes a base frame, a support frame and a transmitting mechanism. The base frame includes front and rear ends. The transmitting mechanism includes a first sliding plate, a second sliding plate and a transmitting assembly. The first and second sliding plates are connected with and slidable relative to the base frame in a front-rear direction. The transmitting assembly includes a rotating axle unit and a linkage unit. The rotating axle unit is movable with the support frame to cause sliding movements of the first and second sliding plates and a pivoting of the linkage unit relative to the base frame so as to shift the first and second sliding plates between retracted and projecting states.
