  • Patent number: 10692667
    Abstract: A keyboard device includes a base, a wing-type connecting element and a keycap. The base plate includes a close-type connecting bracket. The wing-type connecting element includes a first frame and a second frame. A connecting shaft of the second frame is received within the close-type connecting bracket. Consequently, the wing-type connecting element is connected with the base plate. While the keycap is depressed, the connecting shaft is only allowed to be rotated and limited within the close-type connecting bracket. Since the swinging range of the wing-type connecting element is reduced, the keyboard device of the present invention is capable of improving the depressing stability of the keycap.

  • Patent number: 10658137
    Abstract: A key structure includes a support shaft, a resilience sheet, a pedestal and a keycap. While the keycap is pressed down in response to an external force, the support shaft is moved downwardly and the resilience sheet is correspondingly moved. Since a resilience part of the resilience sheet is pushed by a push part of the pedestal, the resilience part is subjected to deformation. After the resilience part is moved across the push part, the resilience part is elastically restored and swung. Consequently, the resilience part collides with the inner surface of the sliding groove to generate a click sound.
