Keyboard, Method of Driving and Assembling the Same, and Electronic Device

A magnetic keyboard, comprising:

• a base plate;
• a keycap, disposed above the base plate and having a first permanent magnet and a second permanent magnet;
• and
• an X-shaped holder, disposed between the base plate and the keycap for supporting the keycap, the X-shaped holder comprising a first lever and a second lever pivotally connected to each other, thus having four ends, wherein one end is pivotally connected to the base plate, one end is slidably connected to the base plate in a sliding direction substantially parallel to the base plate, and a third permanent magnet is provided on the sliding end, an upper surface of the third permanent magnet having the same polarity as those of the lower surfaces of the first permanent magnet and the second permanent magnet,
• wherein the keycap is movable between a first position and a second position lower than the first position along a direction substantially perpendicular to the base plate, and
• wherein the third permanent magnet is in a position substantially opposite to the second permanent magnet when the keycap is in the first position, and the third permanent magnet slides to a position substantially opposite to the first permanent magnet when the keycap is in the second position.

An electronic device, comprising:

• a keyboard, sending out a key value in response to a key-press operation;
• a processing unit, receiving and handling the key value sent out by the keyboard;
• and
• a display unit, displaying a process result of the processing unit,
• wherein the keyboard comprises:
• a base plate, on which a first magnetic member and a second magnetic member are formed;
• a keycap, disposed above the base plate;
• and
• an X-shaped holder disposed between the base plate and the keycap for supporting the keycap, the X-shaped holder comprising a first lever and a second lever pivotally connected to each other, thus having four ends, wherein one end is pivotally connected to the base plate, one end is slidably connected to the keycap in a sliding direction substantially parallel to the base plate, and a third permanent magnet is provided on the sliding end,
• wherein the keycap is movable between a first position and a second position lower than the first position along a direction substantially perpendicular to the base plate, and
• wherein the third permanent magnet is in a position substantially opposite to the second magnetic member when the keycap is in the first position, and the third permanent magnet slides to a position substantially opposite to the first magnetic member when the keycap is in the second position.

A keyboard, comprising:

• a keycap;
• an X-shaped holder for supporting the keycap, the X-shaped holder at least comprising a first member at least having a first pivoting part and a second member at least having a second pivoting part;
• a movable means connected to the first pivoting part;
• and
• a fixed means connected to the second pivoting part,
• wherein the movable means moves to bring the first pivoting part away from or towards the second pivoting part.

An assembling method of a keyboard, the keyboard comprising:

• a keycap;
• an X-shaped holder at least comprising a first member and a second member;
• a movable means;
• and a fixed means, wherein the first member at least has a first pivoting part and the second member at least has a second pivoting part, the method comprising:
• supportively connecting the X-shaped holder to the keycap;
• connecting the movable means to the first pivoting part;
• connecting the fixed means to the second pivoting part;
• wherein the movable means moves to bring the first pivoting part away from or towards the second pivoting part.
