  • Patent number: 11990295
    Abstract: An illuminated keyswitch includes a keycap, a pair of frames adapted to support the keycap in an up-down movement, the pair of frames disposed corresponding to each other and substantially rotatably coupled to each other to define an inner space under the keycap, a pair of elastic members connecting the pair of frames to be located at two opposite sides of the inner space, respectively, and an illumination light source disposed between the pair of elastic members in the inner space and adapted to provide an illumination light. During the up-down movement of the keycap, a vertical projection of the pair of frames surrounds the inner space without interfering therewith, so the illumination light passes the inner space to illuminate the keycap.

  • Patent number: 11978598
    Abstract: A keyswitch structure includes a base, a keycap, a lift mechanism and a light-emitting part. The lift mechanism includes a first support, a second support, and a spring structure. The first support and the second support are connected to and between the base and the keycap, so that the keycap can move relative to the base in a vertical direction. The spring structure is a single structural part and is connected to the first support and the second support and drives the first support and the second support to lift the keycap in the vertical direction. The lift mechanism as a whole defines a central space that extends through the whole lift mechanism in the vertical direction. The spring structure does not enter the central space. The light-emitting part is disposed on the base corresponding to the central zone, and emits light to illuminate the keycap.

  • Publication number: 20240105401
    Abstract: A keyswitch structure includes a casing, a first support, a second support, and a pressing stem. The casing forms an accommodating space and an opening communicating with the accommodating space. The first and second supports are disposed in the accommodating space and are directly and rotatably connected with the casing; the supports are also pivotally connected with each other. The pressing stem extends into the accommodating space to be rotatably connected with the first and second supports and protrudes from the casing through the opening. The pressing stem is movable parallel to a vertical direction relative to the casing through the first and second supports. A motion of the pressing stem in the vertical direction has a top dead center and a bottom dead center. When the pressing stem is at the top dead center and the bottom dead center, it does not touch the casing in the vertical direction.

  • Patent number: 11923159
    Abstract: A keyswitch structure includes a keycap support mechanism and a keycap that is supported by the keycap support mechanism in a vertical direction. The keycap support mechanism includes a base and two supports. The base has two sliding slots. Each sliding slot has an opening in a horizontal direction and an obstruction block at the opening. The horizontal direction is perpendicular to the vertical direction. Each support has a sliding portion and a linkage portion. The sliding portions slide parallel to the horizontal direction in the sliding slots correspondingly. The obstruction block prevents the corresponding sliding portion from disengaging from the corresponding sliding slot. The two linkage portions push against each other in line contact, so that the two supports are mutually driven through the two linkage portions.

  • Publication number: 20150262442
    Abstract: An apparatus for vehicle management and control is provided. The apparatus includes a processing unit, a vehicle lock controller and a non-contactable radio frequency (RF) reader. When an identification (ID) tag approaches to the non-contactable RF reader in a predetermined distance, the non-contactable RF reader reads ID information in the ID tag, and transmits the ID information to the processing unit. The processing unit executes a task according to an interaction relationship between the non-contactable RF reader and the ID tag or a user.

  • Patent number: 8674247
    Abstract: A switch panel with an indicator is disclosed. The switch panel has a transparent region. There is a light source disposed in the switch panel for emitting light when turning off a switch body. A shape of the transparent region is projected onto the wall for forming a large area of indicating pattern, and this can replace a night light. The drawback of a luminous region in prior art which is limited to be on the switch body or on the switch panel is solved.
