  • 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.

    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.
