A keyboard device includes a substrate and several keycaps disposed on the substrate. The substrate includes a long slit and an elastic bridge connecting member. The long slit divides the substrate into a first plate having a first side edge and a second plate having a second side edge opposite to the first side edge. A gap is between the first side edge and the second side edge. The elastic bridge connecting member is connected between the first side edge and the second side edge. The first plate is movable relative to the second plate. The first side edge includes a first stopping member, the second side edge includes a second stopping member, and a certain interval is between the first stopping member and the second stopping member.

The present invention provides a keyboard and a key structure thereof, including: a lower cover, a fixed plate, a plurality of keys, a flexible protection cover, and an upper cover. The fixed plate is fixedly disposed on the lower cover, the keys are fixedly disposed on the fixed plate, the hollow protrusion structure of the flexible protection cover is configured to partially cover a key pedestal of the key, and a key support shaft of the key is correspondingly configured at a position of the opening of the flexible protection cover. The upper cover is disposed on the sheet-like body of the flexible protection cover and is assembled to the lower cover, and the hollow protrusion structure is located in a recess of the upper cover.

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 waterproof electronic device includes a keyboard module, a first case and a first waterproof layer. The keyboard module has a plurality of key caps. The first case is disposed over the keyboard module and the first case has a top surface. The top surface of the first case has a plurality of first opening exposing the key caps. The first waterproof layer covers the top surface of the first case and the key caps, and the first waterproof layer includes a fabric layer and a waterproof adhesive layer.

A laptop keyboard structure includes a keycap assembly and a key shaft assembly. The keycap assembly includes a keycap positioning plate, a plurality of stroke limiting structures and a plurality of keycaps. The stroke limiting structures are respectively disposed on the keycap positioning plate. The keycaps are respectively connected to the stroke limiting structure. The key shaft assembly, detachably assembled to one side of the keycap assembly, includes a circuit substrate and a plurality of key switches. The key switches are disposed on the circuit substrate and used to abut the keycap. A manufacturing method of the laptop keyboard structure is mainly to prepare the keycap assembly first, then to prepare the key shaft assembly, and finally to mount detachably the key shaft assembly to the keycap assembly by having the key switches respectively to penetrate the switch and further abut the keycap.

A keyswitch device includes a circuit board, a fixing bracket, a micro switch, a keycap, and a connecting assembly. The circuit board has a first surface and a second surface opposite to the first surface. The fixing bracket includes a main body and a first hook. The main body abuts against the first surface. The first hook is connected to the main body and fixed to the circuit board. The micro switch passes through the main body, and is disposed on the circuit board and configured to generate a pressing signal to the circuit board while being pressed. The keycap is supported on the micro switch and configured to press the micro switch toward the circuit board. The connecting assembly is connected between the fixing bracket and the keycap and configured to guide the keycap to move upward and downward relative to the circuit board.

An input device includes an upper cover including a plurality of key openings and a keyboard including a base plate disposed on a back side of the upper cover, and a plurality of key tops provided in a front side of the base plate and inserted in the respective key openings. A plurality of hooks, each of which is disposed between the key tops adjacent to each other at a plurality of points and is provided upright on a back surface of the upper cover, fixes the keyboard to the upper cover.
