Keyboard device

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.

A keyboard includes a substrate, a display member, and a keyswitch assembly. The display member is disposed over the substrate. The keyswitch assembly includes a keycap, a fixing element, two balance bars, and a position-returning member. The keycap is located over the substrate and has a light-transmitting portion located over the display member. The fixing element is disposed on the substrate and has a retaining slot. Each of the balance bars includes a rod portion and an end portion. The rod portion is rotatably engaged with the keycap. The end portion is movably retained in the retaining slot. The position-returning member abuts against the keycap above the substrate and is adjacent to an edge of the keycap.

A key structure includes a keycap and a connecting member. The keycap has a bottom surface and includes a fixing portion and an elastic arm. The fixing portion is disposed on the bottom surface, and the fixing portion has a connection hole and a first opening communicating with each other. At least one end of the elastic arm connects to a side surface of the fixing portion, and the elastic arm is adjacent to the first opening. The elastic arm has an open end communicating with the opening and a limiting surface toward the bottom surface. The connecting member includes a connection pin, one end of which connects to the connection hole and the other end of which has an extension portion. The connection pin is disposed in the connection hole, and the extension portion is disposed between the bottom surface and the limiting surface.

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.

Keyswitch device

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.

A keyswitch device includes a bottom plate, a keycap, and a position-returning member. The keycap includes a metal cover and a covering member. The metal cover includes a first main body. The first main body has a first surface and a second surface respectively facing toward and facing away from the bottom plate. The first surface presents a pattern. The covering member includes a second main body covering the first surface. The second main body has a light-transmitting area covering the pattern. The position-returning member is disposed between the bottom plate and the keycap and contacts the first main body.

A keyboard includes a base plate, a hook structure, and a plastic engaging member. The base plate has a top surface. The hook structure is connected to the base plate and raised relative to the top surface. The plastic engaging member is located on the top surface and fixed to at least a part of the hook structure.
