Patent attributes
A keyboard device includes a base plate with a base plate with a connecting bracket, a wing-type connecting element and a keycap. A first connecting shaft of the wing-type connecting element is inserted into the connecting bracket, so that the wing-type connecting element is connected with the base plate. While the keycap is depressed, the first connecting shaft is inserted into a first receiving space of the connecting shaft and used as a swinging fulcrum. Since the vertical movement of the wing-type connecting element is restricted by the first receiving space, the swinging range of the wing-type connecting element is reduced. Consequently, the keyboard device of the present invention is capable of improving the depressing stability of the keycap.
