A folding keyboard includes a number of keypads, a number of telescopic rods arranged on opposite sides of the number of keypads, and a number of connecting cables for electrically coupling the number of keypads together. The number of keypads are combined into a unified piece by the number of telescopic rods being in a contracted state. The number of keypads are separated from each other by the telescopic rods being in an extended state. The number of keypads separated from each other can be stacked on top of each other.

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 a key unit, a membrane switch circuit layer, a vent valve and a pump. The key unit includes a keycap and an elastomer. The vent valve includes an inlet, an outlet and a gas exhaust chamber. The inlet and the outlet are in communication with a gas-inputting port and a gas-outputting port of the membrane switch circuit layer, respectively. The gas exhaust chamber is in communication with the pump. When a sensing element of the base senses that the top cover is close to the base, the pump is enabled to perform a gas-extracting action. The elastomer is subjected to compressed deformation and the keycap is moved downwardly. Consequently, an altitude of the key unit is reduced.

A portable device (e.g., a wireless device such as a cell phone) is provided with a flexible keyboard and a flexible display screen. Such flexible components may be stored in the housing of the portable device when not in use. The flexible display screen and flexible keyboard may be expanded from the housing when the flexible components are utilized by a user. Non-flexible display and input components may be provided on the exterior of the portable device such that the device may be used, in some form, while the flexible components are stored. In one embodiment, a portion of the flexible display (or flexible keyboard) may be utilized when the flexible display (or flexible keyboard) is stored in said first housing.

Switch gear for interconnecting a plurality of power transmission lines including a number of high voltage switches arranged in three phase unitized relationship for routing power in one or multiple directions. The switches are pre-mounted on a beam to form a unitized assembly which is attached in the field to a vertical support structure or substation structure. The unitized assembly includes a telescoping base design that permits the width of the unitized assembly to be reduced so that the assembly can be transported by truck to the installation site and then the switch assembly may be extended to the final width for installation at the site. The telescopic base design is preferably cantilevered and includes free rolling capability for easily manually reducing or expanding the width of the unitized assembly when the beam is lying on a ground surface.

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.

A keyboard module and an electronic device using the keyboard module are provided. The keyboard module includes a housing, a plurality of keys, a micro pump chamber and an actuator. The housing has multiple openings with the keys disposed in the housing. Each key includes a switch membrane, a key cover, an elastic element and a scissor unit. The switch membrane has a key switch, the key cover is above the switch membrane, and the elastic element disposed between the switch membrane and the key cover triggers the key switch when being pressed and deformed. The scissor unit is disposed between the key cover and the switch membrane to support the key cover. The micro pump chamber disposed below the key cover includes a first chamber, a second chamber communicating with the first chamber, a check valve disposed between the first chamber and the second chamber, and an actuator driving the keys to be withdrawn into or protrude out of the openings.

An electronic apparatus having a thinner chassis by pressing keycaps and capable of avoiding an erroneous motion or an erroneous input. An electronic apparatus includes: a key-position setting mechanism configured to interlock with a rotation of a display chassis and a main body chassis via a hinge mechanism to move keycaps from a first position to a second position; and a controller configured to enable a key input signal from the keycaps when the keycaps are at least at the first position and to disable a key input signal from the keycaps when the key-position setting mechanism moves the keycaps to the second position.

A keyboard device includes three detachable keyboard modules. In a stored state, a first base of a keyboard module and a second base of a second keyboard module are located over a third base of a third keyboard module. Moreover, plural key structures of the third keyboard module are accommodated within an accommodation space that is defined by a receiving recess of the first keyboard module and a receiving recess of the second keyboard module. In a usage state, the first keyboard module and the second keyboard module are horizontally combined with two lateral sides of the third keyboard module, plural key structures of the first keyboard module are supported by a first side of the third base and the first base collaboratively, and plural key structures of the second keyboard module are supported by a second side of the third base and the second base collaboratively.
