    摘要： A keyboard device for an electronic device includes a keyboard main body and a protection plate member. The protection plate member is pivotally coupled to the keyboard main body. Consequently, the keyboard main body is covered by the protection plate member, or a first angle is formed between the protection plate member and the keyboard main body. The protection plate member includes a first plate and a second plate. The keyboard main body is pivotally coupled to a first end of the first plate. The second plate is pivotally coupled to a second end of the first plate. After the protection plate member is rotated relative to the keyboard main body and the first angle is formed between the protection plate member and the keyboard main body, the protection plate member is further adjusted to a selected usage mode.

    摘要： A keyboard device includes a base plate, a plurality of key structures, a floating frame and a cover layer. The key structures are disposed over the base plate, and each of the key structures has a keycap. The floating frame is disposed over and separated from the base plate. The floating frame has a plurality of openings, and the key structures are disposed in the openings, respectively. The cover layer covers the keycaps of the key structures and the floating frame and is in direct or indirect contact with an upper surface of the keycap of each of the key structures and an upper surface of the floating frame. When the keycap of one of the key structures and the cover layer thereover are pressed to bottom, the floating frame surrounding the one of the key structures is pulled by the cover layer and shifted.

    摘要： A keyboard device includes a circuit substrate, a control unit and plural touch key structures. The control unit is installed on the circuit substrate. Each touch key structure includes a base plate, a keycap, a connecting element and a touch-sensitive circuit layer. The base plate is detachably installed on the circuit substrate. The keycap is located over the base plate. The connecting element is arranged between the base plate and the keycap. The keycap is movable upwardly or downwardly relative to the base plate through the connecting element. The touch-sensitive circuit layer is arranged between the base plate and the keycap, and electrically connected with the control unit. After a touch signal is received by the touch-sensitive circuit layer, the touch signal is transmitted to the control unit, and the touch signal is converted into an input signal by the control unit.

    摘要： A bendable support device is provided, which includes a support plate, a slidable plate and a pivot mechanism. The support plate has a first portion and a second portion laterally adjacent to the first portion. The slidable plate is disposed over the first portion of the support plate. The pivot mechanism is pivotally connected between the first portion and the second portion. The slidable plate is configured to move toward the pivot mechanism when an angle between a lower surface of the first portion and a lower surface of the second portion is changed from 180 degrees to less than 180 degrees.
