Abstract: A keycap support mechanism increases the stability of supporting a keycap through structure designs of supports. Two supports are pivotally connected around a pivot axis; therein, at least one of the supports includes a support body and a reinforcement part embedded into the support body. The elastic modulus of the reinforcement part is greater than the elastic modulus of the support body. In an embodiment, the reinforcement part has a surrounding portion. The surrounding portion surrounds three sides of a pivot hole of the support. In another embodiment, the two supports both have a reinforcement part. The two reinforcement parts have overlapping portions in a vertical direction. A keyswitch structure includes a base plate, a keycap, and any of the above keycap support mechanisms. The keycap support mechanism supports the keycap above the base plate.

Abstract: A keycap support mechanism increases the stability of supporting a keycap through structure designs of supports. Two supports are pivotally connected around a pivot axis. One of the supports includes a support body and a reinforcement part embedded into the support body. The elastic modulus of the reinforcement part is greater than the elastic modulus of the support body. In an embodiment, the reinforced support includes Z-shaped bending structure extending parallel to the pivotal axis. In another embodiment, the reinforced support has a sliding shaft and a sliding hole formed beside the sliding shaft. The reinforced support is slidably and rotatably connected to the keycap through the sliding shaft. The reinforcement part surrounds the sliding hole and goes through the sliding shaft. A keyswitch structure includes a base plate, a keycap, and any of the above keycap support mechanisms. The keycap support mechanism supports the keycap above the base plate.

Abstract: A keycap lifting mechanism increases the stability of supporting a keycap through structure designs of supports. For example, vertical projections of a sliding hole, a holder hole, and a base hole of supports overlap in a short side direction. For another example, vertical projections of a sliding hole, a holder hole, and a pivot hole of supports overlap in the short side direction. For another example, within the coverage range of a dome hole formed by supports in a long side direction, the supports do not have a structure connecting with other components. For another example, within the coverage range of two arms on opposite sides of the dome hole, there are more than 8 connection portions on the supports for connecting with a keycap and a base plate. For another example, the width of the arm is 0.8 to 2 times the length of the arm.

Abstract: A keycap lifting mechanism increases the stability of supporting a keycap through structure designs of supports. For example, a pivot of two supports overlaps base holes of the supports along the pivot axis. For another example, each of supports has support arms extending non-parallel to the pivot axis. The free end of each support arm is connected to a base plate. For another example, among a plurality of pivotally-connecting structures between supports, at least one includes a fully-open pivot hole, achieved by two opposite hooks, and at least one includes a semi-open pivot hole, achieved by two opposite hooks and a blind hole. A long rectangular keyswitch structure includes a keycap and any of the above mechanisms. The distance from a sliding hole of one support to an adjacent keycap long side is greater than the distance from a holder hole of another support to another adjacent keycap long side.
