  • Publication number: 20160042890
    Abstract: A key structure includes a switch circuit, an elastic member and a press unit. The switch circuit includes a predetermined press area. The elastic member is disposed on the predetermined press area of the switch circuit. The press unit is disposed on the elastic member and includes a flexible membrane and a plate. A part of the flexible membrane forms a press zone corresponding to the plate, wherein a position of the press zone is corresponding to a position of the elastic member, and the plate is fixed with the press zone. As one corner of the press zone is pressed, a corner of the plate moves downward accordingly while an opposite corner of the plate is limited by the flexible membrane from moving upward, such that the whole plate and the whole press zone move downward together to press the elastic member uniformly and trigger the switch circuit.

  • Publication number: 20150279591
    Abstract: A key structure includes a switch circuit, a frame layer, a deformable elastic element and a pressing unit. The switch circuit has a predetermined pressing region. The frame layer is disposed on the switch circuit, and the frame layer has a receiving space. The deformable elastic element is disposed on the switch circuit and received in the receiving space of the frame layer. The pressing unit includes a key body contacting the deformable elastic element. The deformable elastic element is disposed between the switch circuit and the key body, and the contact area between the deformable elastic element and the switch circuit is smaller than the contact area between the deformable elastic element and the key body. Whereby, when a predetermined pressure is pressed upon the pressing unit, the predetermined pressure is balancedly pressed on the predetermined pressing region of the switch circuit through the deformable elastic element.

  • Patent number: 7564967
    Abstract: An electronic device with two-dimensional sliding cover and a two-dimensional slide apparatus are disclosed. The two-dimensional slide apparatus includes a first member, a second member, a third member and a first torque-retaining assembly. The second member is movable along a first direction in relation to the first member. The third member is movable between a first position and a second position along a second direction in relation to the second member, with a first central position therebetween. The first torque-retaining assembly is disposed between the second member and the third member. When the third member moves from the first position or the second position to the first central position by an external force, the first torque-retaining assembly generates torque, driving the third member from the first central position to the first position or the second position.

  • Publication number: 20070238494
    Abstract: A portable electronic device including a first casing, a second casing and a carrier is provided. The first casing has a first surface having a guide slot and a slide slot. The guide slot has a first wide opening, a narrow opening and a second wide opening. The narrow opening is positioned between the first and the second wide openings. The second casing has a second surface. The carrier has an elastomer whose two ends are coupled to two opposite walls of the guide slot. When the elastomer is moved from the first or the second wide opening to the narrow opening, the elastomer is compressed to generate a compressed elastic force. When the elastomer partly passes the narrow opening, the elastomer releases the compressed elastic force and moves towards the first or the second wide opening so that the first casing slides with respect to the second casing.

  • Patent number: 7203532
    Abstract: A hinge mechanism includes a shaft, a cam, a spring and a sliding member. The shaft has a first end and a second end and the cam is movably disposed at the first end and has an inclined plane facing the second end. Also, the spring is disposed at the second end, and the sliding member is disposed on the shaft and is coupled with the spring. The sliding member moves along the shaft due to the elasticity of the spring. In addition, the sliding member has a contact capable of reaching the inclined plane, wherein the cam on which a force is imposed moves toward the second end so that an elastic potential energy is stored as a result of elastic deformation of the spring and the contact of the sliding member presses the inclined plane to rotate the cam by the spring's resilience.

  • Publication number: 20070054710
    Abstract: A portable electronic device including a first body, a second body and a hinge is provided. The hinge includes a carrier, a movable element, an elastomer, a first rotate element and a second rotate element. The elastomer disposed between the carrier and the movable element for enabling the movable element to move reciprocally along an extended direction of the first shaft. The second shaft penetrates through the fourth hole for enabling the second cam to contact with the first cam. The second body is coupled to second rotate element. When the second rotate element rotates to a predetermined position, the second cam abuts against the first cam for enabling the elastomer to provide an elastic force between the carrier and the movable element. The elastic force is for enabling the second rotate element to drive the first rotate element to move synchronously.
