Abstract: A synchronizing hinge includes a rotating module and a bracket plate unit. The rotating module includes two support units pivotably mounted to a base seat. Each support unit has a first support piece, a second support piece pivotably connected with the first support piece, and a moving axle extending through the first support piece and an arcuate slot of the second support piece and movably received in a moving slot of the base seat. The bracket plate unit includes two first bracket plates securely connected with the first support piece, and two second bracket plates securely connected with the second support piece. The support units and the bracket plate unit are rotatable between an initial position where the first bracket plates are flush with the second bracket plates, and a terminal position where the first bracket plates are inclined relative to the second bracket plates by an inclined angle.

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 sliding rail device includes a first rail, a second rail and two supporting units. The first rail includes a first base wall, and two first side walls cooperating with the first base wall to define a first passage. Each of the first side walls has an engaging slot. The second rail engages the first passage, is movable relative to the first rail, and includes a second base wall and two second side walls. The two supporting units respectively and movably engage the engaging slots of the first side walls, and abut respectively and slidably against the second side walls. During movement of the second rail relative to the first rail, the supporting units are driven to respectively move along the engaging slots of the first side walls, and to move toward each other to tighten abutment of the supporting units against the second side walls.

Abstract: A hinge includes a base frame unit and two rotatable axle units. The base frame unit includes a base seat and a protective cover. The base seat has two guideways having upper and lower segments, and two shaft sliding slots. The protective cover has a base wall and two pivot pins. Each axle unit rotatably extends through the base seat, and includes a hinge shaft rotatably extending through the shaft sliding slot, a first rotary member non-rotatably fitted to the hinge shaft, a second rotary member connected with the first rotary member, and a support bracket non-rotatably fitted to the hinge shaft. The first rotary member has a guide key slidably engaged in the guideway. The second rotary member is pivoted to the pivot pin and has an engaging hole for receiving the guide key.

Abstract: A rotation device includes a base seat, an axle unit, a lower rotating module and an upper rotating module. The axle unit includes an upper axle and a lower axle. The lower rotating module includes a lock unit, and an outer barrel that is disposed in the base seat and that is penetrated by the lower axle. The lock unit includes a lock plate that is sleeved on the lower axle, and a lock member that is mounted to 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 upper rotating module is disposed in the base seat and is co-rotatably sleeved on the upper axle. The upper rotating module is able to be driven by the upper axle to rotate relative to the lower rotating module.

Abstract: A hinge is mountable between two casing parts of a flexible electronic device, and includes a base seat and two rotating modules disposed at two sides of the base seat for respectively mounting the casing parts thereon. Each rotating module includes a primary support plate pivotably connected to the base seat, and a secondary support plate pivotably connected to the primary support plate. When the rotating modules are rotated from an initial position, where the secondary support plates are flush with the primary support plates for resting and supporting a flexible display thereon, to a terminal position, where the secondary support plates are turned away to provide a leeway, the casing parts are shifted from an unfolded state to a folded state.

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 foldable electronic apparatus includes a flexible display, a housing unit, and a supporting device. The supporting device includes a flexible first supporting plate, a flexible second supporting plate, and a plurality of supporting members. Each of the supporting members has a first end portion that is connected to the first supporting plate, a second end portion that is connected to the second supporting plate, and a main body portion that has two opposite sides respectively connected to the first end portion and the second end portion. The supporting device is operable to convert between a first state, in which two opposite sides of the supporting device are distal from each other, and a second state, in which the supporting device is folded along a folding axis such that the opposite sides of the supporting device are proximate to each other.
