Technical field
The utility model relates to a kind of computer keyboard, especially relates to a kind of soft-touch type computer keyboard.
Background technology
Keyboard is the input equipment of computing machine.104 common QWERTY keyboards, 107 QWERTY keyboards, notebook type keyboard and Wireless Keyboard adopt the contactless keyboard of condenser type mostly; Belong to non-coding type keyboard according to the code conversion mode, its principle of work is the form that key arrangement is become matrix, by hardware or software at any time to matrix-scanning; In case a certain key is pressed; The microprocessor of keyboard control chip is just according to its position, and the ranks information translation of this key is position code and sends into main frame or directly show key name at display screen, tabled look-up by keyboard driver again; Obtain the ASCII character of button, the keyboard buffer of sending at last in the internal memory supplies main frame to take out temporary instruction analysis execution.Condenser type non-contact type keyboard comprises that all keycap is a keyboard, and the key body of being made up of the silica gel push-button of upper box plate, down box plate and lifting effect.Need mould, injection moulding machine and cost than higher plastic material, be called for short ABS like polystyrene HIPS, vinyl cyanide-BS (AcrylonitrileButadieneStyrene), or their mixture.Particularly these keyboards will firmly knock keycap ability input information, and the use dynamics is more than 60 grams, and long-term use makes the people tired easily, even makes people's arm flesh and lumbar muscle strain, influences people's health.
Summary of the invention
The utility model technical matters to be solved is the defective that exists to the contactless keyboard of existing condenser type, proposes the soft-touch type computer keyboard that a kind of cost of manufacture is lower and the use dynamics is little.
The technical matters of the utility model solves through following technical scheme:
A kind of computer keyboard of this soft-touch type; Unit key body is arranged in the matrix switch form, by the microprocessor of matching used keyboard control chip at any time to matrix-scanning, in case a certain key body is touched; Be enter key position information; Microprocessor is according to touching the position, and the ranks information translation of this key is position code and sends into main frame or directly show key name at display screen, tabled look-up by keyboard driver again; Obtain the ASCII character of button, the keyboard buffer of sending at last in the internal memory supplies main frame to take out temporary instruction analysis execution.
The characteristics of a kind of computer keyboard of this soft-touch type are: being flat layer structure, is protection with top layer fexible film, upper strata flexible printed circuit sheet, to be furnished with unit key body be the insulating trip, lower floor's flexible printed circuit sheet of the corresponding through hole in key position and protect and use the bottom fexible film from top to bottom successively.Two sheets of flexible printed circuit sheet is separated by said insulating trip up and down; When finger or other suitable object touch corresponding insulating trip the top layer fexible film of through hole are arranged; The relative conductive stud body of two sheets of flexible printed circuit sheet forms contact point up and down; The matrix switch that this unit key body is corresponding is closed, enter key position information.
The technical matters of the utility model solves through following further technical scheme:
Said insulating trip is that thickness is the insulating trip of 0.05mm-0.200mm.
Said touching comprises touch and dynamics knocking below 30 grams.
Said top layer fexible film is a transparent membrane, and key position key name is located at the back side of transparent membrane.
The said key name that is located at the transparent membrane back side is the key name of printing.Said top layer fexible film is electroluminescent film or light-emitting film, the luminous demonstration of key position key name.
Also be provided with flexible support chip between said lower floor flexible printed circuit sheet and the bottom fexible film.
Also be provided with the rigid support sheet between said lower floor flexible printed circuit sheet and the bottom flexible protective film, further improve the intensity of touching feel and strengthening keyboard.
The top terminal layer of touching that is pasted with thin keycap on its outer surface that also is provided with of said top layer fexible film.
The center of the relative conduction convex body of the center of said thin keycap and said upper and lower two sheets of flexible printed circuit sheet is on same perpendicular line.
The center of the relative conduction convex body of the center of said thin keycap and said upper and lower two sheets of flexible printed circuit sheet is on same perpendicular line; So that the position is touched in prompting; And have the top layer fexible film of through hole to transmit pressing power downwards through corresponding insulating trip, improve and touch accuracy and reliable operation degree.
Compared with prior art, the advantage and the effect that the utlity model has are:
(1) cost of manufacture is lower, has saved the button that keycap, box plate and the silica gel processed than higher plastic material by cost are processed.
(2) use dynamics is little, touches or dynamics knocking below 30 grams with finger or other object, gets final product input information.
(3) keyboard thickness is ultra-thin, is merely 2mm～8mm, can obviously reduce trucking costs and packing charges.
The keyboard of the utility model can be made into keyboard, Foldable keyboard, notebook type keyboard and the Wireless Keyboard of any key position, is used for the information input of computing machine.
