  • Patent number: 7971317
    Abstract: A hinge assembly and a portable electronic device are provided. The portable electronic device includes a lid, a main body, and a hinge assembly. The hinge assembly pivotly connects the lid to the main body. The hinge assembly includes a pivot element, a torsion spring, and a hinge brace. The pivot element is formed on the lid and partially and rotatably received in the main body. The torsion spring is assembled between the lid and the main body. When the lid is in a closed position with respect to the main body, the torsion spring becomes constricted and accumulates potential energy. When the lid is opened from the main body, the potential energy of the torsion spring is released to drive the lid to rotate to an open position with respect to the main body. The hinge brace is attached to the main body for blocking an excessive rotation of the lid with respect to the main body.

  • Publication number: 20090158552
    Abstract: A flip-type electronic apparatus includes a base panel, a cover, and a latch mechanism pivotably fastening the cover to the base panel. At least one post extends from the cover into the base panel. The latch mechanism includes a button mounted on the base panel, and a sliding bar received in the base panel. At least one limiting portion is formed on one lateral side of the sliding bar receiving the post of the cover. The sliding bar forms a pair of inclined operating surfaces, and the button forms at least one inclined actuating surface abutting at least one of the pair of inclined operating surface. When the button is pressed, the actuating surfaces pushes the operating surfaces to cause the sliding bar to move away from the button, and thus the post is released from the limiting portion for opening the cover of the electronic apparatus.

  • Patent number: 7444651
    Abstract: A casing (10) for an optical disk player includes a body (14) for housing a disk playing mechanism, and a top lid (12). The top lid is closable downward to a closed position for covering at least part of the body, and is openable upward to an open position for loading or unloading an optical disk. A pair of pivot pins (440, 584) is formed on opposite lateral sides of the body respectively, and a pair of pivot holes (220, 34) is defined in opposite lateral sides of the top lid respectively. The pivot pins are movably received in the pivot holes. A resilient member (56) is interposed between the body and the top lid, for resiliently loading the top lid in a direction toward its open position. In assembly, at least one of the pivot pins is insertable into the corresponding pivot hole by deforming the top lid slightly.

  • Publication number: 20050240949
    Abstract: An optical recording/reproducing apparatus includes an upper cover, a lower cover, and several vents. Each vent is arranged on the lower cover, and includes a first grille and a parallel second grille. The first and second grilles each include parallel louvers interleaved by parallel gaps. The first grille is arranged at an outer surface of the lower cover, while the second grille is arranged on an inner surface of the lower cover, with a clearance h separating the first and second grilles. Heat produced in the optical recording/reproducing apparatus is expelled out from the housing via the gaps of the second grille and the gaps of the first grille. However, external dust or contaminants that may enter the gaps of the first grille are blocked from entering the housing by the louvers of the second grille.
