Abstract: A three-section slide rail device includes an outer section, a middle section and an inner section. The middle section includes a middle rail slidably disposed on the outer section, a ball sliding plate slidably disposed on the middle rail, and a leaf spring at one end of the middle rail. The ball sliding plate has a plate body, a synchronizing block and a positioning hole formed on the plate body. The inner section includes an inner rail and a synchronizing actuating member pivotably mounted to the inner rail. The synchronizing actuating member is in an abutting engagement with the synchronizing block during an extended movement of the inner section relative to the middle section to make synchronizing movement of the ball sliding plate with the inner section until the positioning hole of the ball sliding plate is engaged with the leaf spring.

Abstract: A hinge includes a stationary seat and two rotating units. Each rotating unit includes a linkage module that has an extension body that has a arcuate slide rail, a rotating bracket module that is rotatable and that has a fixing pin, and a sliding module that includes a connecting frame, a positioning pin, and a linkage member. The connecting frame has a curved groove that engages the arcuate slide rail such that movement of the rotating units between an opened and a closed state results in movement between the arcuate slide rail and the curved groove. The linkage member has a through hole, and an elongated slot which the fixing pin passes through to connect the rotating bracket module such that movement of the rotating units between the opened and closed states results in movement between the fixing pin and the elongated slot.

Abstract: A displaceable rotating shaft structure and a foldable device having the rotating shaft structure are disclosed. The displaceable rotating shaft structure comprises a support, a rotating shaft, a connecting rod assembly, a guide assembly, and a torsion assembly. The support has a supporting portion. The connecting rod assembly has a first outer end that is rotatably connected to the linking section of the rotating shaft and a second outer end that is pivotally connected to the supporting portion. The guide assembly has a guide rod. The guide rod is configured to displace relative to the supporting portion. When the rotating shaft is rotated, the rotating shaft drives the connecting rod assembly to adjust the angle and the total length of a joint of connecting rods of the connecting rod assembly, a distance between the rotating shaft and the support is changed through the guide assembly.

Abstract: A hinge synchronization module includes a base unit, and two hinge units. The two hinge units are connected to the base unit, and each of the hinge units has a gear member, a rotating platform, and a connecting member. The gear members of the hinge units mesh with each other. The rotating platform of each hinge unit has a platform body pivotable relative to the base unit. The connecting member of each hinge unit has a gear part mashing with the gear member of the hinge unit, and a slide hole. A slidable rod of the rotating platform of each hinge unit is disposed in and slidable along the slide hole of the connecting member of the hinge unit.

Abstract: A hinge includes two rotatable axle units each having two hinge shafts, two synchronizing units each disposed to make synchronous rotations of the hinge shafts, two movable bracket units each having a turnable base plate, two rotary blocks non-rotatably sleeved on the hinge shafts, and two movable plates movable relative to the rotary blocks, and two guiding bracket units, each having male and female arms respectively connected with two movable plates, and a plurality of guiding connecting members interposed between the arms. Each guiding connecting member has a protrusion and a sliding groove, and is angularly movable with the rotations of the hinge shafts. Removal of the protrusion from the sliding groove of an adjacent guiding connecting member is prevented by means of engagement of an abutting portion of the protrusion with an abutted block in the groove.

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.
