A film contact type optical keyboard

Abstract

The invention provides a thin-film contact type optical keyboard, which comprises keys, and each key comprises a keycap which protrudes out of the surface of the keyboard; a key body which is arrangedbelow the key cap and used for providing elastic restoring force, and a bottom plate which is arranged below the key body and used for triggering the key to output a key signal, wherein the key bodycomprises a shell and an axis embedded in the shell, the bottom plate is provided with a conductive thin film, the conductive thin film and the shaft core are oppositely arranged at an interval, and the key body enable the axis to abut against the conductive thin film under the action of pressing force, so that one-time key operation is completed. Compared with the prior art, the thin film contacttype optical keyboard provided by the invention is high in lightness and thinness, is convenient to disassemble, is easy to maintain and is cost-saving.

Description

technical field [0001] The invention relates to the field of computer auxiliary equipment, in particular to a film contact type optical keyboard. Background technique [0002] In order to allow user input for electronic devices, keyboards are generally known in the art. The keyboard includes several keys located in several recesses or openings in the top portion of the keyboard. The key may be electrically connected to a printed circuit board located within the electronic device. Usually includes similar specs as a keyboard. In other words, at least a portion of the printed circuit board underlies each key. A printed circuit board may include several switches or other components such that when a key is pressed, one of the switches or other components is activated. [0003] With the rapid development of portable notebooks, thinning, miniaturization and high integration have become sought after by computer manufacturers and users. This requires computer auxiliary equipment...

Problems solved by technology

[0003] With the rapid development of portable notebooks, thinning, miniaturization and high integration have become sought after by computer manufacturers and users. This requires computer auxiliary equipment, especially the keyboard on portable notebooks, to also meet the requirements of thinning and lightening. Most of the notebook keyboards in the prior art use keycaps, pressing structures and circuit board structures, wherein the pressing structure often adopts the contact mode, that is, adopts silica gel to touch the conductive film, and the scissors balance structure is used as support, so that The key switch is thick due to the setting, and the number of press life is low, and the click sound from keyboard typing cannot be realized.
