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 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.

Abstract: A hinge includes: a base seat that includes a rack extending in a front-back direction; a moving platform that is movable on the base seat along the front-back direction; and a shaft unit that includes a rotating shaft rotatably extending through the moving platform in a left-right direction, a main gear member rotatably extending through the moving platform, co-movable with the moving platform, and meshed with the rack to constitute a rack and pinion system, and a first bevel gear piece fixedly sleeved on the rotating shaft, and meshed with the main gear member such that rotation of the rotating shaft results in collective linear front-back motion of the shaft unit and the moving platform relative to the base seat.

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 device is adapted to be installed between two machine bodies that are mounted with a flexible display. The hinge device includes a base member, two rotating modules mounted respectively to opposite sides of the base member and adapted for the machine bodies to be mounted respectively thereto, and a central support plate disposed above the base member and connected between the rotating modules. The central support plate is drivable by the rotating modules to move relative to the base member from a supporting position, where the flexible display is flat and is supported thereby from below, to a receding position, where a display receiving space is provided for receiving a bent portion of the flexible display.

Abstract: An electronic device includes a base cover, a cover plate which is slidable relative to the base cover among a closed position, an open position, and a transition position, and a slide positioning mechanism which is configured for positioning the cover plate relative to the base cover, and which has first and second magnetically attractive units. When the cover plate is in a selected one of the closed and open positions, a magnetically attractive force is generated to position the cover plate in the selected one of the closed and open positions. When the cover plate is in the transition position, a magnetically repulsive force is generated to facilitate movement of the cover plate away from the transition position.

Abstract: A supporting device includes a dual-shaft hinge module and two buffering modules respectively arranged at two opposite sides of the dual-shaft hinge module. Each dual-shaft hinge module includes two shafts, a linking member clamped between the two shafts, and two side wing members respectively and slidably installed on the two shafts. The two buffering modules are respectively installed on the two shafts and are respectively cooperated with the two side wing members. Each buffering module includes an internal connecting member fixed on and synchronously rotatable with the corresponding shaft and an external connecting member slidably disposed on the internal connecting member and provided to be fixed on a carrying plate. Each side wing member has a limiting portion passing through the corresponding internal connecting member and the corresponding external connecting member.
