  • Patent number: 10734174
    Abstract: The disclosure generally relates to a keyboard and, more particularly, to a silent keyboard. A first pressing portion is formed of two strengthening strip elements intersected with each other, and utilized to enhance the rigidity and stability of four guiding pillars. Two grooves are formed on the inner walls of a first frame. Two hooks positioned in opposing sides and two silencing strip elements positioned in opposing sides are formed on the underside of a first key cap and extend outward from the first key cap. The two hooks respectively engage with the two grooves, while each hook is arranged to operably slide along a corresponding groove. The two silencing strip elements engage with the inner walls of the first frame, so that a first key structure can slide steadily within the first frame and does not tilt while sliding.

    Abstract: A key mechanism for an electronic device includes a switch housing and a hinged structure. As one example, the hinged structure can be a butterfly hinge. The switch housing includes switch pin retaining mechanisms on opposing sides of the switch housing. The hinged structure includes two separate wings that are positioned adjacent to each other such that a cavity is formed between the two wings. The two wings are coupled together by coupling elements. The wings of the hinged structure can include switch housing pins on each arm of the wing that extend into the cavity and couple to the switch pin retaining mechanisms in the switch housing. Various configurations of switch pin retaining mechanisms and switch housing pins can be used to attach the hinged structure to the switch housing.

  • Patent number: 9966202
    Abstract: A keyswitch includes a cap, a support structure, a first magnet, and a baseplate having a bending arm protruding from the baseplate and a support rib extending horizontally to form a receiving space with the bending arm. The support structure includes a first support member pivoted to the baseplate and against the cap and a magnetic permeable plate extending from the first support member and being above the receiving space. The first magnet is inserted into the receiving space to be supported by the support rib and be pressed by the bending arm. When the cap is pressed to make the magnetic permeable plate away from the first magnet as the first support member rotates, the cap moves to a pressed position. When the cap is released, a magnetic attraction force between the magnetic permeable plate and the first magnet drives the magnetic permeable plate to approach the first magnet.

  • Patent number: 9959991
    Abstract: A keyswitch uses a magnetic attraction force produced between and by a fixed part, fixedly disposed relative to a base, and a movable part, movably disposed relative to the base, as a driving force for returning a keycap to its original position. The movable part is between the fixed part and the base. The keyswitch also uses a force transmission part disposed between the keycap and the movable part as an intermediate for transferring force from the keycap to the movable part. When a force for pressing the keycap downward overcomes the magnetic attraction force, the movable part moves toward the base and then triggers a switch.

    Abstract: A key structure includes a supporting plate, a keycap, a scissors-type connecting element, a movable element and a coupling structure. The keycap is disposed over the supporting plate. The coupling structure is connected with the scissors-type connecting element and the movable element. For operating the key structure, the cooperation of the movable element and the coupling structure allows the keycap to be at a higher first height. Consequently, the tactile feel of depressing the key structure is enhanced. Moreover, the cooperation of the movable element and the coupling structure can lower the height of the keycap. Consequently, the key structure has a slim appearance.

  • Patent number: 9773626
    Abstract: A keyboard includes a base plate, plural keycaps, plural scissors-type connecting elements and a sliding plate. Each scissors-type connecting element has a bulge. The gliding plate has plural position-limiting structures. The keyboard is installed on a notebook computer and connected with a top cover of the notebook computer. For operating the keyboard, the bulge is received in a first step part of the position-limiting structure. Consequently, the keycap is at a higher height. Since the keycap is at a higher height, the movable distance of the keycap is large enough to provide better tactile feel. For storing the keyboard, the bulge of the scissors-type connecting element is moved to the second step part of the position-limiting structure. Consequently, the height of the keycap is reduced, and the keyboard has a slim appearance.
