Abstract
A key structure includes a keycap, an elastic buffering element, a base plate, a first supporting element, a second supporting element and an elastomer. The elastic buffering element is installed in a locking part of the keycap. The first supporting element is connected with the keycap and the base plate. The keycap is movable upwardly or downwardly relative to the base plate through the first supporting element. A first end of the second supporting element is pivotally coupled to the base plate. A second end of the second supporting element is penetrated through a pivotal hole of the elastic buffering element and a clamping recess of the locking part. The elastomer is arranged between the keycap and the base plate. An inner diameter of the at least one pivotal hole is slightly smaller than an inner diameter of the clamping recess.
Claims15
A key structure, comprising:
- a keycap, wherein at least one locking part is disposed on a bottom surface of the keycap, wherein the at least one locking part comprises a clamping recess;
- an elastic buffering element comprising a pivotal pedestal with at least one pivotal hole, wherein the elastic buffering element is installed in the at least one locking part, and the at least one pivotal hole is aligned with the clamping recess;
- a base plate;
- a first supporting element connected with the keycap and the base plate, wherein the keycap is movable upwardly or downwardly relative to the base plate through the first supporting element;
- a second supporting element, wherein a first end of the second supporting element is pivotally coupled to the base plate, and a second end of the second supporting element is penetrated through the at least one pivotal hole and the clamping recess;
- and
- an elastomer arranged between the keycap and the base plate, wherein the elastomer is permitted to provide an elastic restoring force to the keycap,
- wherein an inner diameter of the at least one pivotal hole is slightly smaller than an inner diameter of the clamping recess.
