Publication number: 20170278651Abstract: 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.Type: ApplicationFiled: May 20, 2016Publication date: September 28, 2017Inventor: YI-CHEN WANG

Publication number: 20170200571Abstract: 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.Type: ApplicationFiled: March 8, 2016Publication date: July 13, 2017Inventor: YI-CHEN WANG
