  • Publication number: 20220342455
    Abstract: A portable electronic device including a first body, a second body, a pivot element, a heat source, a first flexible heat conductive element, and a flip cover is provided. The pivot element is connected to the second body, and the second body is pivotally connected to the first body through the pivot element. The heat source is disposed in the first body. The first flexible heat conductive element is thermally coupled to the heat source and extends toward the pivot element from the heat source. The first flexible heat conductive element passes through the pivot element and extends into the inside of the second body and is thus thermally coupled to the second body. The flip cover is pivotally connected to the first body and located on a moving path of the pivot element.

  • Publication number: 20220137674
    Abstract: A hinge mechanism includes at least two hinge modules and at least one switching assembly disposed between the adjacent two hinge modules and including a first and second rotating members rotating coaxially with respect to each other. The first rotating member is coaxially disposed at one of the adjacent hinge modules to rotate synchronously. The second rotating member is coaxially disposed at the other one of the adjacent hinge modules to rotate synchronously. The first rotating member has a first driving portion, and the second rotating member has a second driving portion. The first and second driving portions are located on rotating paths of each other, and an idle stroke is provided between the first and second driving portions along the rotating paths. When the first driving portion and the second driving portion pass through the idle stroke, torque forces generated by the adjacent two hinge modules are disconnected.
