Description

Ultrathin keyboard and electronic equipment

Technical Field

The utility model relates to the technical field of computer hardware structure design.

Background

Referring to fig. 1, the existing keyboard of the notebook computer is independent of a keyboard shell (a mechanism C), the key includes a keycap and an elastic component arranged below the keycap, and a key circuit is arranged below the key, the keyboard with such a structure has a slow response speed, and in addition, the thickness of the key circuit part needs to be added to the thickness of the whole keyboard, so that the whole thickness of the keyboard cannot be further reduced.

Disclosure of Invention

In view of the shortcomings of the prior art, the present invention provides an ultra-thin keyboard with low overall thickness and high speed.

In order to achieve the above purpose, the present invention provides an ultra-thin keyboard, comprising a keyboard shell, a key array, a key circuit and a MICOM chip, wherein the key array comprises a plurality of keys, each key comprises a keycap and an elastic component arranged below the keycap, the key circuit comprises a fixed line arranged in the keyboard shell and a motion line arranged on each keycap, when any keycap is pressed down, the motion lines are separated from the fixed lines, and the MICOM chip obtains key signals corresponding to the keys.

Preferably, the fixed line is embedded in the keyboard housing.

Preferably, the MICOM chip establishes an (X, Y) coordinate system on the key array through a key position circuit, and when the key cap is pressed, the MICOM chip obtains a key position signal corresponding to the key through a logic level change of the received signal.

Preferably, the key array is 6X 16, and the MICOM chip establishes a coordinate system (X0-X5, Y0-Y15) on the key array through a key position circuit.

Preferably, when the key at the (Xn, Yn) position is pressed, the moving line is separated from the fixed line, and the MICOM chip obtains a low level signal at the (Xn, Yn) position.

According to another invention of the present invention, there is provided an electronic apparatus including the ultra-thin keyboard as described above.

Preferably, the mobile terminal comprises any one of a notebook computer, a desktop computer and a multimedia all-in-one machine.

The utility model has the beneficial effects that: the space of the original key position loop part can be saved, so that the thickness and the weight of the whole notebook computer are reduced; the corresponding loop can generate level change at the moment of pressing the keycap, and the faster reflecting speed of the key is realized.

Detailed Description

The following detailed description of the preferred embodiments of the present invention is provided to enable those skilled in the art to more readily understand the advantages and features of the present invention, and to clearly and unequivocally define the scope of the present invention.

Referring to fig. 2 to 4, fig. 2 is a schematic view of a keyboard according to the present invention, and fig. 3 and 4 are schematic views of the operation of the keyboard according to the present invention. The ultrathin keyboard in the embodiment comprises a keyboard shell 1, a key array 2, a key circuit 3 and a MICOM chip 4, wherein the key array 2 comprises a plurality of keys 5, each key 5 comprises a keycap 6 and an elastic part 7 arranged below the keycap 6, the key circuit 4 comprises a fixed line 8 arranged in the keyboard shell 2 and a moving line 9 arranged on each keycap 6, when any keycap 6 is pressed down, the moving line 9 is separated from the fixed line 8, and the MICOM chip 4 obtains a key signal corresponding to the key 5.

The fixed circuit is embedded in the keyboard shell (mechanism C piece), and the moving circuit 9 is arranged on the key cap 6. The MICOM chip 4 establishes an (X, Y) coordinate system on the key array through a key position circuit, and when the key cap is pressed, the MICOM chip obtains a key position signal corresponding to the key through a logic level change of the received signal.

For example, a common full-keyboard fake plate can adopt a coordinate system with a key array of 6X 16, twenty pins of a MICOM chip establish (X0-X5, Y0-Y15) on the key array through a key position circuit. All the X, Y coordinate signals are high level by default, and when the key at the (Xn, Yn) position is pressed, the moving line is separated from the fixed line, and the MICOM chip obtains a low level signal at the (Xn, Yn) position.

The scheme of the utility model can be widely applied to various electronic equipment comprising keyboards, such as notebook computers, desktop computers, multimedia all-in-one machines and the like. The space of the original key position loop part can be saved, so that the thickness and the weight of the whole notebook computer are reduced; the corresponding loop can generate level change at the moment of pressing the keycap, and the faster reflecting speed of the key is realized.

The above embodiments are merely illustrative of the technical concept and features of the present invention, and the present invention is not limited thereto but may be implemented by those skilled in the art, and all equivalent changes and modifications made according to the spirit of the present invention are included in the scope of the present invention.
