  • Publication number: 20170278651
    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.

  • Patent number: 9739309
    Abstract: The present disclosure discloses an active compensating hydrostatic bearing which includes a body, a mass block and a elastic member. The body includes a compensation hole and holds the mass block and the elastic member inside. The elastic member is put between the mass block and the compensation hole for generating a compensation gap near the compensation hole. By resisting the compression from the mass block, the elastic member can control the compression of the compensating gap so as to stabilize the rigidity of the bearing.

  • Publication number: 20170200571
    Abstract: A key structure includes a keycap, a scissors-type connecting element, a metal triggering element, a switch circuit board, a base and a buffering element. The buffering element is integrally formed with the keycap, and fixed on an inner surface of the keycap. The buffering element is made of a soft material. As the keycap is depressed and moved, the buffering element is pushed by the keycap and subject to deformation. Consequently, the movable distance of the keycap is increased. That is, the tactile feel of depressing the keycap is enhanced.

  • Publication number: 20170117107
    Abstract: An illuminated keyboard with an optical switch is provided. The illuminated keyboard includes a circuit board and plural keys. The circuit board includes plural light-emitting elements. Each light-emitting element is aligned with the corresponding key. The key includes a keycap, a housing, a triggering post, a light guide element and a light guide frame. The keycap is located over the housing. The triggering post, the light guide element and the light guide frame are disposed within the housing. Moreover, the light guide frame is arranged around the triggering post. After a light beam emitted by the light-emitting element is introduced into the housing, the light beam is guided to the light guide frame by the light guide element, and the light beam is scattered to a region around the triggering post and outputted from the keycap.
