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 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.

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: 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 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 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 a fixed seat, and two symmetrically-disposed support modules that are convertible between an unfolded state and a folded state. Each of the support modules includes a sliding pivot arm that is slidable and pivotable with respect to the fixed seat, a pivot guide unit that is movably engaged with the sliding pivot arm, and a slide block that has a slide slot movably engaged with the sliding pivot arm, and an oblique sliding portion movably engaged with the pivot guide unit, such that the slide block is slidable with respect to the sliding pivot arm and the pivot guide unit when the support modules are converted between the unfolded state and the folded state.

Abstract: A hinge connectable with two housing parts to allow opening and closing thereof includes a mounting seat, two rotary units and two lateral support plates. The mounting seat has two first arcuate slots at two sides of a central line. The rotary units are connected with the mounting seat at the two sides of the central line for mounting the housing parts, and shiftable between an unfolded state and a folded state. Each rotary unit includes a linking member, a rail sliding block, a rotating bracket and an interposed sliding member interposed between the rail sliding block and the rotating bracket. The sliding of the rail sliding block relative to the rotating bracket can be steady and firm without the need to elongate the inclined rails of the rail sliding block and the rotating bracket, which renders the hinge more compact and slim.
