    Abstract: To provide an opening and closing device which can eliminate the torque fluctuations and ensure a secure unlocking, the opening and closing device based on biaxial hinge ensures that, when the second casing is opened from the close position to the initial opened position, and the stopper plate rotates relative to the first hinge shaft up to the initial opened position, the hinge shaft switcher switches from restraints to the rotation of the first hinge shaft to those to the rotation of the second hinge shaft, thus fixes the stopper plate at the initial opened position. The opening torque of the second casing is merely the sum of the torsion torque of the torsion spring and the friction torque of the first free stop tilting mechanism, and not subject to torque fluctuations. Therefore, the second casing can be securely opened.

  • Patent number: 9021659
    Abstract: A hinge structure includes a first shaft, a second shaft, a pivot base and a position-limiting mechanism. The first and second shafts are pivoted on the pivot base. The position-limiting mechanism includes a first position-limiting portion, a second position-limiting portion and a position-limiting component. The first position-limiting portion is fixed to the first shaft. The second position-limiting portion is fixed to the second shaft. The position-limiting component is slidably disposed on the pivot base and has first and second ends opposite to each other. When the position-limiting component moves to a first position, the first end and the first position-limiting portion interfere with each other to stop the first shaft and the pivot base from rotating relatively. When the position-limiting component moves to a second position, the second end and the second position-limiting portion interfere with each other to stop the second shaft and the pivot base from rotating relatively.

  • Patent number: 9009919
    Abstract: A steady opening and closing double-axis hinge comprises a first rotation member, a second rotation member and a connection member run through by the first rotation member and the second rotation member in a parallel manner. The first rotation member includes a first shaft and a first sector portion formed on the first shaft. The second rotation member includes a second shaft and a second sector portion formed on the second shaft. The connection member includes a movable detent plate which is located between the first and second shafts and movable between a first operation position and a second operation position. Through the movement of the movable detent plate, the first sector portion and second sector portion can be blocked alternately to control the first and second shafts to rotate in sequence, so as to simplify the shaft rotation switch mechanism and improve the durability.

  • Patent number: 8991011
    Abstract: A hinge mechanism for a foldable electronic device is provided. The hinge mechanism includes a hinge, a pivot part and a friction part. The hinge and the pivot part are fixed to a first body and a second body of the foldable electronic device respectively. The friction part is connected to the pivot part and selectively contacting the hinge. When the pivot part rotates relative to the hinge to drive the first body to rotate from a close position to an open position in relative to the second body, the friction part does not contact the hinge. When the pivot part rotates relative to the hinge to drive the first body to rotate from the open position to the close position in relative to the second body, the friction part contacts the hinge and limits a rotation of the pivot part on the hinge.

  • Patent number: 8978209
    Abstract: A hinge structure includes a first shaft, a second shaft, a sliding component, a first pillar, and a second pillar. The second shaft is parallel to the first shaft. The sliding component includes a first sliding portion and a second sliding portion, wherein the first shaft and the second shaft are disposed through the first sliding portion and the second sliding portion respectively, and the first sliding portion has a first guiding slot and the second sliding portion has a second guiding slot. When the first shaft rotates with respect to the sliding component and moves the first pillar along the first guiding slot, the first pillar drives the sliding component to slide along the first and second shafts and move the second pillar along the second guiding slot, so as to drive the second shaft to rotate with respect to the sliding component.

  • Patent number: 8959719
    Abstract: A dual-shaft synchronous movement device includes a first shaft and a second shaft, which are synchronously rotatable. The synchronous movement device further includes a first rotor and/or a third rotor disposed on the first shaft and a second rotor and/or a fourth rotor disposed on the second shaft, and an inextensible/non-contractible flexible plate connected between the first (or the third rotor) and the second rotor (or the fourth rotor). When the first shaft drives the first rotor (or the third rotor) to rotate, the inextensible/non-contractible flexible plate pulls the second rotor (or the fourth rotor) to rotate in a direction reverse to a moving direction of the first rotor so as to make the first and second shafts synchronously rotate. The synchronous movement device solves the problem of delay of kinetic energy transmission and the problem of slippage, deflection and untrue operation of the conventional device.

  • Patent number: 8959720
    Abstract: A synchronous movement device of dual-shaft system includes a first shaft and a second shaft, which are assembled with each other and synchronously rotatable. The synchronous movement device further includes a driver disposed on the first shaft and a reactor disposed on the second shaft and a link unit connected between the driver and the reactor. The driver is formed with a driving rail. The reactor is formed with a reacting rail. When the first shaft drives the driver to rotate, the driver pushes the link unit to move along the first and second shafts to forcedly push the reactor to rotate in a direction reverse to the moving direction of the driver. Accordingly, the first and second shafts are synchronously rotated.

  • Patent number: 8898860
    Abstract: A hinge device for rotatably moving a closing element includes a fixed element anchorable to a stationary support structure coupled to a movable element anchorable to the closing element for rotating around a first longitudinal axis between an open position and a closed position. The device further includes at least one slider movable along a second axis between a compressed and an extended position. One between the movable element and the fixed element includes at least one operating chamber defining the second axis so as to slidably house the slider, the other element including a pivot defining the first axis. The pivot and the slider are reciprocally coupled so that to the rotation of the movable element around the first axis corresponds the sliding of the slider along the second axis and vice versa.
