Description
Technical field
The utility model relates to keyboard, especially relates to a kind of soft-touch type computer keyboard.
Background technology
Keyboard is the input equipment of computer.104 common QWERTY keyboard, 107 QWERTY keyboard, 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 operation principle 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, the ranks information translation of this key is position code and sends into main frame or directly show key name at display screen, table look-up by keyboard driver again, obtain the ASCII character of button, the keyboard buffer of sending at last in the internal memory takes out temporary instruction analysis execution for main frame.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, (Acrylonitrile Butadiene Styrene is called for short ABS, or their mixture as polystyrene HIPS, acrylonitrile-butadiene-styrene copolymer.Particularly these keyboards will firmly knock keycap ability input information, and the use dynamics is more than 60 grams, and long-term use makes people's fatigue easily, even makes people's arm flesh and lumbar muscle strain, influences people's health.
Summary of the invention
Technical problem to be solved in the utility model is the defective that exists at 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.
Technical problem of the present utility model is solved by following technical scheme:
This soft-touch type computer keyboard, 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, the ranks information translation of this key is position code and sends into main frame or directly show key name at display screen, table look-up by keyboard driver again, obtain the ASCII character of button, the keyboard buffer of sending at last in the internal memory takes out temporary instruction analysis execution for main frame.
The characteristics of this soft-touch type computer keyboard 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 described 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 closure of this unit key body correspondence, enter key position information.
Technical problem of the present utility model is solved by following further technical scheme:
Described insulating trip is that thickness is the insulating trip of 0.05mm～0.200mm.
Described touching comprises touch and dynamics knocking below 30 grams.
Described top layer fexible film is a transparent membrane, and key position key name is located at the back side of transparent membrane.
The described key name that is located at the transparent membrane back side is the key name of printing.
Described top layer fexible film is electroluminescent film or light-emitting film, the luminous demonstration of key position key name.
Also be provided with the rigid support sheet between described 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 described top layer fexible film,
The center of the center of described thin keycap and the relative conduction convex body of described upper and lower two sheets of flexible printed circuit sheet on same vertical line,
The center of the center of described thin keycap and the relative conduction convex body of described upper and lower two sheets of flexible printed circuit sheet is on same vertical line, so that the position is touched in prompting, and have the top layer fexible film of through hole to transmit pressing power downwards by corresponding insulating trip, improve and touch accuracy and functional reliability.
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 made than higher plastic material by cost are made.
(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, only is 2mm～8mm, can obviously reduce freight and packing charges.
Keyboard of the present 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 computer.
