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a check valve disposed between the first chamber and the second chamber, and an actuator driving the keys to be withdrawn into or protrude out of the openings.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.

Disclosed herein is a stack-up for an input device. The stack-up may include a flexible substrate having a switch and a light source. The switch has at least two contacts that are bridged in response to actuation of a dome that is positioned above the switch. The flexible substrate includes a signal trace for detecting the actuation of the dome and a power trace for providing power to the light source.

An electronic device disclosed. The electronic device includes a first chassis, a second chassis, and a hinge mechanism that connects the first chassis and the second chassis. The electronic device also includes a cylindrical cam member, a slide member and a movable member that moves in conjunction with a movement of the slide member in the axial direction and which extends from and retracts to an outer surface of the first chassis.

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 input device includes a housing which has an opening, button parts which are exposed from the opening and which are pressed down in a first direction, a support component which has a support part to support the button parts, a first surface to face the housing, a second surface provided opposite to the first surface, and fixation parts provided at a first distance from the support part and fixed to the housing on a side of the first surface, a substrate which is provided so as to face the second surface of the support component, and a component which is inserted into the substrate in the first direction and which presses a specified area of the second surface, positioned at a second distance shorter than the first distance from the support part, toward the housing in a direction opposite to the first direction.

A key structure includes a first movable plate, a second movable plate, a keycap, a first linkage lever and a second linkage lever. The second movable plate is disposed over the first movable plate. The keycap is disposed over the second movable plate. The first linkage lever is connected with the keycap and the first movable plate. The second linkage lever is connected with the keycap and the second movable plate. While the first movable plate is moved in a first direction and the second movable plate is moved in a second direction, the first linkage lever and the second linkage lever are moved in different directions, so that a height of the keycap is reduced.
