  • Patent number: 9013866
    Abstract: A driving mechanism for driving a display module to move relative to a host module includes a display module fixing component disposed in the display module, a host module fixing component movably disposed in the host module, and a pivoting component. An end of the pivoting component is pivotally connected to the display module fixing component and another end of the pivoting component is fixed to the host module fixing component. The pivoting component drives the host module fixing component to move as being pivoted by the display module fixing component. The driving mechanism further includes at least one protruding structure disposed on the host module fixing component and capable of moving relative to an inner side of the host module in line contact manner or point contact manner as the pivoting component drives the host module fixing component to move.

  • Patent number: RE40055
    Abstract: A position unit is mounted on an electronic device and includes a catch member and a locking member. The catch member defines a gap which has a width that is reducible when the catch member moves from a non-catching position to a catching position and that is expandable when the catch member moves from the catching position to the non-catching position. The locking member has an engine end extending into the gap. The locking member is operable to move the catch member from the non-catching position to the catching position and from the catching position to an urging position. The engaging end of the locking member engages the catch member when the width of the gap is reduced upon movement of the catch member to the catching position. The engaging end of the locking member disengages from the catch member when the width of the gap is enlarged upon movement of the catch member to the non-catching position.
