Abstract: A keyboard device includes a substrate, a keycap, and a link member. The keycap is disposed on the substrate and provided with a limiting member including a top wall, a bottom wall, and a slide groove. In the slide groove, the top wall has a first guide bevel and the bottom wall has a second guide bevel. The link member is disposed between the substrate and the keycap and includes a slide connection portion and a pivot connection portion. The slide connection portion is slidably disposed in the slide groove, and the pivot connection portion is pivotally connected to the substrate. When the keycap is pressed to move downwardly toward the substrate, the pivot connection portion of the link member is rotated with respect to the substrate, and the slide connection portion slides along the first guide bevel and the second guide bevel.

Abstract: A key structure includes a bottom plate, at least one keycap, and a thin-film circuit board. The bottom plate has at least one elastic protruding portion. The keycap is liftably connected to the bottom plate and has a press portion and at least one trigger portion. The press portion is located at a central region of the keycap and faces the elastic protruding portion, and the trigger portion is located at a peripheral region of the keycap. When the key is lowered from a first position to a second position relatively to the bottom plate, the press portion downwardly presses the elastic protruding portion, and the press portion triggers an electrical trigger point of the thin-film circuit board. The keycap is adapted to be restored from the second position to the first position through an elastic force of the elastic protruding portion.

Abstract: A keyswitch device includes a connecting member and a keycap. The connecting member has an engaging shaft. The keycap includes a pressing body and a shaft hole structure. The pressing body has a bottom surface. The shaft hole structure is connected to the bottom surface and has an engaging trough and an inlet passage communicated with each other. The engaging shaft is rotatably engaged in the engaging trough. The inlet passage has a first inner wall and a second inner wall opposite and parallel to each other. The first inner wall and the second inner wall are inclined relative to the bottom surface of the pressing body.

Abstract: A keyboard includes a base plate, a keycap, and a link bar. The base plate includes a plate body and a linkage structure. The linkage structure is connected to and bended relative to the plate body. A through hole is formed at a connecting edge between the plate body and the linkage structure. The keycap is located over the base plate. The link bar includes a first rod body, a second rod body, and an engaging block. The first rod body is engaged with the keycap. The second rod body is connected to the first rod body and passes through the through hole. The engaging block is connected to an end of the second rod body and blocked by the linkage structure.

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.
