Abstract: A key structure includes a baseplate, a keycap and a connecting assembly. The keycap includes a plurality of first pivot portions and a plurality of sliding slots. The connecting assembly includes a first outer frame, two first inner frames, a second outer frame and a second inner frame. The first inner frames are disposed in two accommodating portions of the first outer frame. Two sides of the first outer frame are respectively connected to part of the sliding slots and the baseplate. Two sides of the first inner frame are respectively connected to the first pivot portion and the base plate. Two sides of the second outer frame are respectively connected to part of the sliding slots and the fixing side. Two sides of the second inner frame are respectively pivoted to one of the first inner frames and the base plate.

Abstract: A keyboard device includes a substrate, a keycap, a first connection member, and a first elastic arm structure. The substrate has a top surface, and the top surface has an assembling region. The keycap is disposed above the assembling region, and the keycap has a bottom surface facing the assembling region. The first connection member is connected between the keycap and the assembling region, the first connection member includes a first assembly side and a second assembly side opposite to the first assembly side, the first assembly side is pivotally connected to the bottom surface of the keycap, and the second assembly side is pivotally connected to the substrate. The first elastic arm structure includes a connection end and a free end opposite to the connection end, the connection end is connected to the first assembly side, and the free end abuts against the bottom surface of the keycap.

Abstract: A key module includes a bracket, a circuit film assembly, a keycap, and a connecting structure. The bracket includes a bottom plate and a bracket pivotal portion protruding from the bottom plate. The circuit film assembly is disposed on the bracket and includes a plurality of film layers and a supporting portion formed by at least one of the film layers. The supporting portion is located beside the bracket pivotal portion. The keycap is disposed above the bracket and the circuit film assembly and includes a keycap pivotal portion. The connecting structure is disposed between the bracket and the keycap and includes a first pivot pivotally disposed at the bracket pivotal portion and a second pivot pivotally disposed at the keycap pivotal portion. The supporting portion beside the bracket pivotal portion supports the first pivot, such that the first pivot continuously contacts the bracket pivotal portion.

Abstract: A key includes a substrate, a keycap, a connection component, and protruding structures. The connection component includes a first connection member and a second connection member, and the first connection member and the second connection member are between the substrate and the keycap. The protruding structures are disposed on the upper surface of the first connection member and disposed on the upper surface of the second connection member. When the keycap is pressed to a pressed position, the protruding structures on the first connection member and on the second connection member abut against the bottom surface of the keycap, so that a gap is formed between the keycap and the connection component. Therefore, the bottom surface of the keycap does not contact the upper surface of the first connection member and the upper surface of the second connection member so as to prevent from generating keystroke noises.

Abstract: A keyboard device includes a base plate and a plurality of keyswitches disposed on the base plate. At least one of the keyswitches includes a keycap, two linkages, and two magnetic attraction members. The linkages are connected between the base plate and the keycap and configured to guide the movements of the keycap toward and away from the base plate. The magnetic attraction members are rotatably connected to the linkages, respectively, and are configured to attract each other. When the magnetic attraction members abut against each other, the keycap is at a highest position relative to the base plate. When the keycap moves toward the base plate from the highest position, the magnetic attraction members are separated from each other.
