In one example, a keyboard device may include a base plate, a pivoting support fixedly disposed on the base plate and having a recess portion, a key cap support having a shaft portion rotatably received in the recess portion, a rolling element disposed between the shaft portion and the pivoting support, and a key cap assembled to the key cap support.

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.

The present disclosure discloses a keyswitch with supporting mechanism. The keyswitch comprising a supporting mechanism disposed between the keycap and the baseplate, wherein the keycap is able to move up and down relative to the baseplate, wherein the supporting mechanism comprises a first supporting element, on which two opposite first side surfaces respectively comprise a first connecting part; and a second supporting element, on which two opposite second side surfaces respectively comprise a second connecting part, the first connecting parts are pivotally connected to the corresponding second connecting parts, wherein two protrusions are respectively disposed on each of the two first side surfaces of the first supporting element, two smooth surfaces are respectively formed on each of the two protrusions, and the first connecting parts are respectively disposed on each of the two protrusions.

A keyboard device includes a base plate, a membrane circuit board and a key. The key includes a keycap, a connecting assembly, a first stabilizer bar and a second stabilizer bar. The connecting assembly is connected between the keycap and the base plate. The first stabilizer bar and the second stabilizer bar are connected between the keycap and the connecting assembly. While the keycap is moved upwardly or downwardly relative to the base plate, the first stabilizer bar and the second stabilizer bar are swung to stabilize the key. Since the first stabilizer bar and the second stabilizer bar are connected between the keycap and the connecting assembly, the first stabilizer bar and the second stabilizer bar will not readily collide with or knock on the base plate. During the operation, the generated noise is reduced. Consequently, the operating comfort to the user is enhanced.

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.

A seesaw switch includes a rocker configured to rock by a press operation; a first fulcrum located at least at one end portion in a longitudinal direction of the rocker; a second fulcrum located between the one end portion and another end portion opposite to the one end portion in the longitudinal direction of the rocker; and a main switch disposed on the another end portion opposite to the one end portion at which the first fulcrum is located in the rocker and configured to have contact with the rocker due to rock of the rocker by the press operation, wherein a fulcrum of the rocker is switched between the first fulcrum and the second fulcrum in accordance with an amount of the press operation to the another end portion opposite to the one end portion at which the first fulcrum is located in the longitudinal direction of the rocker.

A slider structure for a keyboard comprising a housing, a depressible actuator disposed in the housing, and a chambered track configured to receive a balance bar structure, the balance bar structure operable to provide a structural support that resists a key cap coupled to the frame from tilting as a force applied at any point on the top surface of the key cap. When the depressible actuator is depressed, the depressible actuator is operable to push the balance bar structure causing the balance bar structure to rotate within the chambered track. The frame and depressible actuator are comprised of a rigid material and the chambered track is comprised of a compliant material that attenuates sound caused by the rotating of the balance bar structure within the chambered track.

Provided are an electronic device, including a side frame, a signal triggering element fixedly disposed inside the side frame, and a button configured to extend through the side frame. The side frame defines a button hole directly facing the signal triggering element, and a limiting protrusion is arranged on an inner wall of the button hole. The button includes: a button post, extending through the side frame and disposed adjacent to the signal triggering element; a button cap, connected to the button post and engaged with the button hole; and a snap board, fastened to a side of the button cap facing the signal triggering element, wherein the snap board is configured with a hook engaged with the limiting protrusion for limiting.

An electronic device can include a first electronic component, a second electronic component, and an energy dampener positioned between and in contact with the first electronic component and the second electronic component. The energy dampener in this example includes a carbon nanotube-aerogel matrix including carbon nanotubes embedded in an aerogel with a rubber composited therewith.

An electronic device includes a keyboard. The keyboard includes a base plate and keys disposed on a base plate. The base plate includes a back support plate, a membrane, and a backlight plate. The membrane and the backlight plate are disposed on two sides of the back support plate. The back support plate supports the membrane, the backlight plate, and the keys. In addition, a buffer structure is disposed on a surface of a side that is of the backlight plate and that faces the key. The back support plate is provided with a first through hole. The key is disposed on a side that is of the membrane and that is away from the back support plate. A protrusion is disposed on a side that is of the key and that faces the base plate. The key moves toward the base plate. The protrusion can press the buffer structure.
