  • Foldable electronic device
    Patent number: 7643857
    Abstract: A foldable electronic device (100) has at least two components hinged together by a hinge assembly. The foldable electronic device includes: a cover (10), a rotating element (20), an elastic element (30) and a frame (40), a set of magnetic elements (50) and a body (60). The rotating element has two notches defined therein. The elastic element has a latching portion. The elastic element is fixed in the rotating element. The frame slidably engages with the rotating element. The frame is engaged with the cover. The rotating element rotatably connects with the body. The magnetic elements make the cover close relative to the body. When the latching portion of the rotating element engages in different notches of the rotating element, magnetic force between the magnetic elements decreases so as to open the cover relative to the body.
