Abstract: A rotation device includes a base seat, an axle unit and a lock unit. The axle unit extends into the base seat. The lock unit includes a lock plate that is sleeved on the axle unit, and a lock member that is disposed on the base seat. The lock plate is formed with a first lock groove. The lock member has a lock portion that is operable to move into the first lock groove. The lock plate is locked by the lock portion of the lock member when the lock portion moves into the first lock groove, so that the axle unit and the lock plate are not rotatable relative to the base seat.

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 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 three-section slide rail device includes an outer section, a middle section and an inner section. The middle section includes a middle rail and an inner middle block. The inner section includes an inner rail slidably disposed on the middle rail, and a removal operating assembly disposed on the inner rail. The removal operating assembly has a removal operating member, a removal connecting plate and a removal locking member pivotably mounted on the inner rail and having a removal guiding slot. The removal locking member has a locking portion and a protrusion. The removal operating member is operated to move the removal connecting plate and bring the protrusion to move along the removal guiding slot to result in pivoting of the removal locking member so as to disengage the locking portion from the inner middle block for permitting removal of the inner section from the middle section.

Abstract: A hinge is connectable with two housing shells for permitting relative folding and unfolding of the housing shells, and includes a fixed seat, at least two rotating units, two lateral support plates and at least one synchronous driving unit. The rotating units are shiftable between an open state and a closed state. Each rotating unit includes a linking member fittingly and arcuately slidable on the fixed seat, a sliding member fittingly and arcuately slidable on the linking member, and a rotary bracket pivotably mounted on the fixed seat and inclinedly slidable on the sliding member. The lateral support plates are respectively mounted on the linking members. The synchronous driving unit includes two inboard pinions and two outboard pinions arranged laterally to mesh with bracket toothed portions of the rotary brackets to make synchronous rotation of the rotary brackets in opposite rotational directions.

Abstract: A hinge is connectable with two housing shells for permitting relative opening and closing of the housing shells, and includes a fixed seat, at least two rotating units, two lateral support plates and a center support plate. The rotating units are disposed at two sides of a centerline of the fixed seat and are connectable with the housing shells. The rotating units are shiftable between an open state and a closed state. Each rotating unit includes a linking member arcuately slidable on the fixed seat. The lateral support plates are mounted on the linking members, and have central notches. The center support plate is movably disposed on the fixed seat and is moved with the rotating units. In the open state, the center support plate is disposed in the central notches. In the closed state, the center support plate abuts against the fixed seat.

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 flexible circuit tension keeping device mountable on an electronic device includes a base seat having opposite first and second surfaces such that a flexible circuit board is bent to surround the first and second surfaces, at least one sliding member slidably disposed on the base seat in a front-rear direction, and spring members disposed between the base seat and the sliding member. The sliding member has a tense surface which is engaged with the flexible circuit board such that a pulling force generated as a result of rotation of a second device part relative to a first device part of the electronic device is applied to the flexible circuit board to move the tense surface of the sliding member toward the base seat, and the sliding member is biased by the spring members to keep tense of the flexible circuit board.

Abstract: A hinge includes two rotatable axle units disposed on a base seat and each having two rotatable hinge shafts, two movable bracket units each including a base plate, two rotary blocks non-rotatably sleeved on the hinge shafts, and two movable plates movable relative to the rotary blocks, and two synchronizing units for making synchronous rotations of the hinge shafts. Each synchronizing unit includes a first gear member having two end surfaces in form of bevel gears, and two second gear members each meshing with the respective end surface and fitted to the respective rotary block. Rotations of the hinge shafts at one side of the base seat result in rotations of the rotary blocks and the second gear members, and bring in rotations of the second gear members, the rotary blocks and the hinge shafts at the other side to make the synchronous rotations.
