    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.

    Abstract: A keyboard device includes a keyboard base, a flexible protection cover and a protective frame. The flexible protection cover is located over the keyboard base to cover the key structures that are disposed on the keyboard base. The protective frame is disposed on the flexible protection cover. Moreover, plural hollow protrusion structures of the flexible protection cover are partially penetrated through corresponding openings of the protective frame and exposed outside the protective frame. The elastic buffering parts of the flexible protection cover are disposed within corresponding concave structures of the protective frame and covered by the protective frame.

    Abstract: The present invention relates to a keyboard, including a base plate, a connecting element, a keycap, and a hook. The connecting element is separately connected to the hook and the base plate. The hook is disposed on an inner surface of the keycap and is connected to a connecting shaft of the connecting element. The hook includes a first fixing portion and a second fixing portion. The first fixing portion is in contact with a first side of the connecting shaft, and the second fixing portion is in contact with a second side of the connecting shaft. The structure of the second fixing portion in the hook is stronger than the structure of the first fixing portion, so that when the connecting shaft is applied with a force to be out of the hook, the first fixing portion is applied with an interference force to be broken, thereby having a recognizing effect.

    Abstract: A keyboard device includes a membrane circuit board, a key frame, a position-limiting frame and a key structure. The key frame is located over the membrane circuit board. The position-limiting frame is located over the key frame. The key frame includes a first frame body and a first receiving hole. The first receiving hole runs through the first frame body along a vertical direction. The position-limiting frame includes a second frame body and a second receiving hole. The second receiving hole runs through the second frame body along the vertical direction. The second receiving hole is in communication with the first receiving hole. The key structure includes a keycap and a protrusion part. The keycap is movable within the first receiving hole and the second receiving hole. A portion of the protrusion part is located under the second frame body.

    Abstract: A luminous keyboard includes at least one key, a switch circuit board, a supporting plate, a backlight module, a reflecting plate and a light-sheltering plate. The backlight module emits a light beam. The backlight module is arranged between the reflecting plate and the light-sheltering plate. A periphery region of the reflecting plate and a periphery region of the light-sheltering plate are thermally laminated or laser welded to define a sealed structure. Since the periphery region of the backlight module is sealed by the sealed structure, the light beam is not leaked out through the periphery region of the backlight module. The space occupied by the sealed structure is not very large. Consequently, the volume of the luminous keyboard is reduced.
