Abstract
The utility model provides a touch luminous keyboard structure, which comprises a PMMA lens, a touch detecting unit and a PCB. The touch detecting unit comprises a transparent ITO conductive film. A plurality of touch keystroke zones are etched on the ITO cladding of the conductive film. The touch detecting unit is bonded to the undersurface of the PMMA lens. A plurality of luminous elements corresponding to the touch keystroke zones are arranged on the PCB. The PCB is connected with the cable interfaces of the touch detecting units. The PCB is arranged under the PMMA lens, and is 4 to 8mm from the touch detecting unit with an air layer between as an air scattering layer for the light from the luminous elements. As the touch detecting unit is not arranged on the PCB with the luminous elements, the design of the multi-keystroke PCB is significantly eased; the assembling cost is reduced; the transmitted light is uniform, and the luminous keyboard structure feels good when the luminous keyboard structure is touched.
Description
Technical field
The utility model relates to the illuminated keyboard technology that touches, specifically be to touch a kind of touch illuminated keyboard structure that the pcb board of detection part and band light-emitting component is provided with at interval, its touch is effective, the light that appears is even, the touch area greatly reduces the design difficulty of the pcb board that requires many buttons not on pcb board.
Background technology
The existing following four kinds of modes of the general employing of illuminated keyboard that touch.
Mode one: between PMMA eyeglass (being the acrylic eyeglass) and PCB, adopt conductive sponge, adopt the LED lamp on the next door of conductive sponge.The shortcoming of this kind mode is to be not together in light-emitting zone and touch area, misleads user's operation easily.
Mode two: touching PCB touch area perforate, the soldering surface mounted LED lamp from the PCB back side, light see through opening area makes the hollow out character of transparent PMMA eyeglass luminous.This kind structure is because PCB is close to the PMMA eyeglass, the distance that 2mm is only arranged between LED lamp and the PMMA material, cause the luminous very little zone line that concentrates on, illumination effect is extremely inhomogeneous, under the little situation of touch key-press light-emitting zone, can use, require this kind structure not realize greater than the light-emitting zone of 2mm.
Mode three: on the basis of mode two, increased light guide plate, can effectively overcome the problem of non-uniform light at the touch PCB back side, but must be measure-alike with the hollow out character boundary in the touch area perforate, just can make character luminous evenly.But owing to the hollow out of circuit board is in change big become greatly of meeting along with the size in hollow out zone, and the touch area can reduce thereupon.Therefore, for the design that big hollow out zone requires, the sensitivity of its touch key-press will inevitably be affected.
Mode four: on the basis of mode three, light guide plate is added between PMMA eyeglass and the PCB.This kind method has overcome the hollow out zone cannot too big problem, but owing between PMMA eyeglass and PCB, added one deck light guide plate, make the distance between PMMA touch area and the pcb board increase, introduced one deck air layer (between PMMA eyeglass and the light guide plate) again, the sensitivity of touch key-press is extremely low.Simultaneously, for comparatively intensive many buttons, this kind method can't realize that each button is independent luminous.
Summary of the invention
Above-mentioned defective in view of the prior art existence, the utility model provides a kind of touch illuminated keyboard structure, the touch detection part is arranged between the pcb board of transparent PMMA eyeglass and band light-emitting component, and make touch detection part and pcb board that certain intervals be arranged, the light that comes self-emission device is by the abundant scattering of air layer in this interval, make the light that appears even, touch effectively, assembly cost reduces.
Touch illuminated keyboard structure of the present utility model is to realize like this, it comprises the PMMA eyeglass, touches detection part and pcb board, described touch detection part comprises transparent ITO conducting film, etch some touch key-presss zone on the ITO of transparent ITO conducting film (tin indium oxide) coating, this touch key-press zone is connected to the winding displacement interface; Touch the lower surface that detection part single face gum is pasted on the PMMA eyeglass; The corresponding light-emitting component in some touch key-presss zone with described touch detection part is set on pcb board, pcb board is connected with the winding displacement interface that touches detection part by its winding displacement socket, pcb board is installed in below the PMMA eyeglass, and and having 4-8mm at interval between the touch detection part, the air layer in this interval is as the air scattering layer that comes the light of self-emission device.
The utility model has following some advantage:
1.PCB plate and PMMA eyeglass keep 4-8mm at interval, the air layer conduct in this interval comes the air scattering layer of the light of self-emission device, makes the abundant scattering of light, and the light that character zone appears from the PMMA eyeglass is even.
2. touch detection part of the present utility model adopts transparent ITO conducting film, and the touch key-press of transparent ITO conducting film zone and PMMA eyeglass are pasted together, and the centre does not have air layer, and the sensitivity of its button is very high, touch effective,
3. owing to touch detection part not on the pcb board of band light-emitting component,, greatly reduce the design difficulty of pcb board for the design of many buttons.
4. it is very big that the touch key-press zone on the transparent ITO conducting film can be done, and shape can be selected arbitrarily and the plastic cement shell of PMMA eyeglass below can cooperate, and can realize that each key area is independent luminous, simple in structure, effectively reduces assembly cost.
Description of drawings
Fig. 1 is an exemplary embodiments structural representation of the present utility model;
Fig. 2 is that the touch detection part of Fig. 1 and pcb board are in conjunction with synoptic diagram.
Embodiment
Describe in detail below in conjunction with embodiment.
With reference to Fig. 1,2, illustrated embodiment comprises PMMA eyeglass 1, touches detection part 2 and pcb board 3, is arranged between the pcb board of transparent PMMA eyeglass and band light-emitting component touching detection part.
Be provided with on the PMMA eyeglass 1 and the 22 corresponding characters zones 11, some touch key-presss zone that touch detection part 2, the lower surface silk-screen clear coat of this character zone, as the green transparent coating etc., the lower surface silk-screen opaque coating that other is regional.The lower surface that detection part 2 single face gums are pasted on PMMA eyeglass 1 will be touched.
The light-emitting component 31 corresponding with some touch key-presss regional 22 of described touch detection part is set on pcb board 3, pcb board 3 is connected with the winding displacement interface 23 that touches detection part by its winding displacement socket 32, pcb board 3 is installed in below the PMMA eyeglass 1, and and being provided with 5mm or 6mm interval between the touch detection part 2, the air layer in this interval is as the air scattering layer that comes the light of self-emission device.
Being pasted on the touch detection part 2 of PMMA eyeglass 1 lower surface and the interval between the pcb board 3 selects between 4-8mm usually, air layer in this interval is the scattering of light layer of light-emitting component, at interval big more dispersion effect is good more for this, and the light that the character zone window appears from the PMMA eyeglass is even more.
In the interval between pcb board 3 and touch detection part 2 scattering sheet (not shown among Fig. 2) can be installed also, this scattering sheet can adopt commercially available mobile phone scattering sheet, the used materials such as scattering sheet of LCD display to make, with further enhancing light scatter effect.The thickness of this scattering sheet can be 0.2-1.5mm.
