A keyboard (110) comprises a base board (116), keys (112), pitfalls (120) and a mode control mechanism (118). The keys (112) include cups (1124), and the mode control mechanism (118) may switch the keyboard (110) especially the key cups (1124) between different modes. In case that the keyboard (110) is not in use, these cups (1124) can be received in the pitfalls (120) to reduce the profile of the keyboard (110). In case that the keyboard (110) is to be used, the keys (112) may be raised up and arranged on the base board (116) in order to enable long keystroke and provide good typing experience.

A waterproof keyboard structure and an assembly method thereof are provided. The waterproof keyboard structure includes a keyboard module, and a keyboard frame framing on the keyboard module, wherein an elastic waterproof layer is formed by means of double injection or insert molding on the keyboard frame. The keyboard module is defined with a key surface, and an assembly surface arranged back-to-back to the key surface. The elastic waterproof layer is clad on the key surface, and the keyboard module with the assembly surface facing a seat is assembled together with the keyboard frame in an accommodating space, thereby having the elastic waterproof layer closely fit with the seat to form a waterproof ring.

A low-cost electronic device capable of storing keycaps within a chassis is disclosed. The electronic device includes a support plate; a set of keycaps supported above the top face of the support plate, the keycaps moving up and down between the operating position and the storage position; and a frame functioning as a driving member that is movable relative to the keycaps in the direction parallel to the top face of the support plate. Each keycap has a pressure-receiving part. The frame has pressing parts that move relative to the keycaps to come in contact with the pressure-receiving parts.

A hinge device can detect an open angle and an opening/closing angular velocity with high responsiveness and simple configuration. The hinge device enables rotary motion of a main-body chassis and a display chassis, and includes a first chassis shaft non-rotatably provided with respect to the main-body chassis, a second chassis shaft non-rotatably provided with respect to the display chassis, a cylindrical body into which the first chassis shaft is inserted to rotate with rotary motion thereof, a ring-type magnet non-rotatably fixed to the cylindrical body, a sensor that detects a movement of the magnet associated with the rotary motion from the change of magnetism, and a controller that reads a signal from the sensor to calculate an open angle and an opening/closing angular velocity.

Embodiments provide a keyboard device having high versatility and high waterproof performance and an electronic device having the keyboard device. A keyboard device has a base plate having a plurality of attachment holes through which a plurality of hook members provided in a body chassis of an electronic device can be passed or with which the plurality of hook members can be engaged in the lower surface, a reflection sheet, which is a sheet-like member covering the lower surface of the base plate, and a plurality of keytops provided on the upper surface of the base plate, in which the reflection sheet is provided with cut lines cut in the thickness direction at positions overlapping with the attachment holes in the vertical direction.

Examples disclosed herein relate to a power button. Examples include a device including a power button to activate a power supply of the device. A controller of the device to determine whether the device is in disabled power event state and to disable the power button when the device in the disabled power event state.

A liftable keyboard for a portable electronic device is provided. The portable electronic device includes a top cover and a base. The liftable keyboard includes at least one key unit, a membrane switch circuit layer and a micro pump. Each key unit includes a keycap and an elastomer. When a sensing element within the base of the portable electronic device senses that the top cover is close to the base, the micro pump is enabled to perform a gas-extracting action. Consequently, the gas in the elastomeric chamber is extracted so that the elastomer is subjected to compressed deformation. The keycap is moved downwardly in response to the compressed deformation of the elastomer so as to reduce an altitude of the at least one key unit.

An information handling system integrated keyboard selectively retracts and extends keys based upon detected conditions, such as housing configuration, housing motion and end user indications. Extension and retraction shuttle plates motivated by actuator wires moves a sliding plate to extended and retracted positions that define the key positions. Nickel titanium alloy actuator wires shorten upon application of current to pull the shuttle plates to the extended or retracted positions that are maintained by a lock. Limit switches remove current at detection of a desired shuttle plate position. One or more controllers manage actuator wire operation based upon detected conditions and actuator wire temperature and electrical characteristics.

The present invention relates to a keyboard, including a first baseboard, a second baseboard, a deformation element, a key cap, and a connecting element. The deformation element is disposed between the first baseboard and the second baseboard and is capable of deforming according to a received voltage signal. The deformation element drags the second baseboard to move in a first direction when the deformation element receives the voltage signal and therefore deforms to be in an extended state, so that the key cap is at a first height. The deformation element pushes the second baseboard to move in a second direction when the deformation element does not receive the voltage signal and therefore deforms to be in a bent state, so that the key cap is at a relatively shorter second height.
