Embodiment
For making the purpose of this utility model, structure, feature and function thereof there are further understanding, cooperate embodiment to be described in detail as follows now.
Please refer to Fig. 1, Fig. 1 is the schematic diagram of the disclosed illuminated keyboard 1 of the utility model.Keyboard 1 has loam cake 50 and a plurality of button 3.Please refer to Fig. 2, Fig. 2 is first embodiment generalized section of a button 3 wherein of keyboard 1.As shown in the figure, luminous button 3 comprises circuit board 10, pedestal 21, keycap 22, elastic component 31 and printed layers 23.Loam cake 50 then is arranged on the button 3.In first embodiment, circuit board 10 can be film circuit board, but the keycap 22 of its corresponding top and elastic component 31 places have the switch 11 that pressurized triggers.Pedestal 21 is arranged on the circuit board 10, structure that itself and keycap 22 can be one of the forming or the element of opening in two minutes.
Fulcrum 25 between keycap 22 and the pedestal 21 is connected in pedestal 21 parts for keycap 22, and forming the cantilever type button, and keycap 22 is made by light-transmitting materials or transparent material.Keycap 22 has upper surface 221 and lower surface 222, and wherein upper surface 221 is the surface that knocked by the user up.Lower surface 222 is relative upper surface 221 downward surfaces towards circuit board 10.Printed layers 23 has different literal or pattern for corresponding different keycaps, in first embodiment, printed layers 23 is set directly on the lower surface 222 of keycap 22, it includes transparent area 231 and light tight district 232, and these transparent areas 231 and light tight district 232 then form literal or the pattern that institute's desire shows.Because therefore the characteristic of keycap 22 printing opacities own or transparent material sees through keycap 22 and can see the pattern that is positioned at the printed layers 23 on keycap 22 lower surfaces 222, to reach the display effect of light-permeable keyboard from keyboard 1 top.
The elastic component 31 of button 3 (preferably being rubber washer) then is arranged between switch 11 and the keycap 22, and in the embodiment of part, light-permeable keyboard 1 can comprise film 30, and the elastic component 31 of each button 3 then is arranged on the film 30.When keycap 22 is pushed by the user and when moving down, elastic component 31 also compressive deformation makes the switch 11 of an actuation part 311 squeeze-activated belows of its below to produce corresponding signal.
Please refer to Fig. 3 A and Fig. 3 B, Fig. 3 A is the schematic diagram of the printed layers 23 in the button 3.As shown in the figure, printed layers 23 is divided into transparent area 231 and light tight district 232, because the covering of light tight district 232, makes to show printed layers 23 formed patterns on the keycap 22 of transparent or printing opacity.Perhaps please refer to Fig. 3 B, Fig. 3 B is the schematic diagram of the printed layers 23 ' in the button 3.The transparent area 231 that also can be shown in printed layers 23 ' and the configuration in light tight district 232.
Please refer to Fig. 4, Fig. 4 is second embodiment generalized section of a button 5 wherein of illuminated keyboard 1.In a second embodiment, the keycap 22 of button 5 has press section 223 and extension 224, wherein extension 224 extends loam cake 50 times, therefore when keycap 22 pressurizeds and when mobile vertically, horizontally extending loam cake 50 can only prop up the extension 224 of keycap 22, therefore can limit keycap 22 and surpass horizontal line and beating of making progress.31 of the elastic components of button 5 are arranged between switch 11 and the extension 224, and printed layers 23 then is arranged on film 30 tops, present pattern to see through keycap 22 transparent or printing opacity.Because elastic component 31 is below press section 223, between the press section 223 of keycap 22 and circuit board 10 (or the film 30 at elastic component 31 places), provide a unseparated space, therefore can not stop the pattern displaying of disturbing printed layers 23.In addition, because the cantilever structure of keycap 22, therefore with respect to fulcrum 25, the extension 224 of keycap 22 is positioned at a distance along horizontal direction, that is extension 224 and fulcrum 25 apart from d
2Greater than press section 223 and fulcrum 25 apart from d
1Can effectively increase elastic component 31 thus and clearly knock finger sense (click).
Please refer to Fig. 5, Fig. 5 is the 3rd embodiment generalized section of a button 7 wherein of illuminated keyboard 1.In the 3rd embodiment, the press section 223 of the keycap 22 of button 7 and extension 224 as previously mentioned, printed layers 23 also is arranged on film 30 tops, presents pattern to see through keycap 22 transparent or printing opacity.Button 7 comprises illuminating module 40 in addition, it comprises light guide plate 41 and light-emittingdiode 42, light guide plate 41 is arranged on the below (film circuit board 10 also is the structure of transparent or printing opacity) of circuit board 10, light-emittingdiode 42 then is arranged on a side of light guide plate 41, and cabling (the cabling part of light-emittingdiode 42 then is not shown on the figure) on circuit board 10.In this embodiment, illuminated keyboard 1 uses illuminating module 40 to produce light source in addition, so that active luminous visual effect to be provided.Because illuminating module 40 is arranged on circuit board 10 belows, light-emittingdiode 42 is launched via light guide plate 41 average making progress through the light that current drives produces, and through the transparent area 231 in circuit board 10 and the printed layers 23, and outwards disperse via keycap 22 (transparent or light-transmitting materials), therefore can present the luminous button effect of the pattern that has on the printed layers 23.
Please refer to Fig. 6, Fig. 6 is the 4th embodiment generalized section of a button 9 wherein of illuminated keyboard 1.In the 4th embodiment, the press section 223 of the keycap 22 of button 9 and extension 224 as previously mentioned, illuminating module 40 then is arranged between circuit board 10 and the elastic component 31 film 30 of elastic component 31 (or have).23 of printed layers can be arranged on circuit board 10 or the light guide plate 41, present pattern to see through keycap 22 transparent or printing opacity.For the effective actuation switch 11 of the actuation part 311 that makes elastic component 31, be arranged at light guide plate 41 between elastic component 31 and the circuit board 10 and have the through hole 43 of corresponding elastic component 31 and switch 11 positions, the actuation part 311 of elastic component 31 then can be passed through hole 43 with actuation switch 11.Because in button 9, the transparent area 231 of the press section 223 of keycap 22, film 30, light guide plate 41, printed layers 23 and film circuit board 10 are all the material of printing opacity, therefore in this embodiment, the light that illuminating module 40 produces provides active luminous visual effect, and can show the pattern that printed layers 23 is had outside button 9.
Illuminated keyboard provided by the utility model has a plurality of keycaps made from light-transmitting materials or transparent material, and between the non-lower surface and circuit board that is contacted of keycap, then according to each keycap the printed layers with different pattern is set.The pattern of printed layers is made of transparent area and light tight district.Illuminated keyboard can add below keycap that the illuminating module of being made up of light-emittingdiode and light guide plate is to produce self luminous light source in addition.So can in it, show literal or the pattern that printed layers is different,, avoid keyboard to knock simultaneously and cause wearing and tearing and dirty in the use to highlight the visual characteristic of illuminated keyboard via printing opacity or transparent keycap.
The utility model is described by above-mentioned related embodiment, yet the foregoing description is only for implementing example of the present utility model.Must be pointed out that the embodiment that has disclosed does not limit scope of the present utility model.On the contrary, change and the retouching done in not breaking away from spirit and scope of the present utility model all belong to scope of patent protection of the present utility model.
