  • Patent number: 11145475
    Abstract: A keyboard device includes plural key structures. Each key structure includes a plate assembly, a keycap, a connecting member and a buffering element. The plate assembly has a hollow region. The keycap is located over the plate assembly. The connecting member is connected between the keycap and the plate assembly. The keycap is connected with the connecting member through at least one hook of the keycap. The keycap is movable upwardly or downwardly relative to the plate assembly through the connecting member. The buffering element is installed on the plate assembly. The buffering element is extended in a direction toward the keycap and penetrated through the hollow region of the plate assembly. While the keycap is moved downwardly and the at least one hook of the keycap is contacted with the buffering element, there is the gap between the keycap and the plate assembly.

  • Patent number: 10607793
    Abstract: A keyboard device includes a base plate and a key structure. The key structure includes a keycap, a first connecting element, a second connecting element and a stabilizer bar. The first connecting element and the second connecting element are arranged between the base plate and the keycap and connected with the base plate and the keycap. The stabilizer bar is fixed on the first connecting element and the second connecting element. Since the stabilizer bar does not collide with the base plate to generate the unpleasant noise, the keyboard device of the present invention is capable of reducing the noise. Moreover, since the stabilizer bar is fixed on the first connecting element and the second connecting element, it is not necessary to install hooks corresponding to the stabilizer bar on the keycap and the base plate and the fabricating cost is reduced.
