See also Fig. 3.Fig. 3 illustrates the synoptic diagram according to the illuminated keyboard 3 of the utility model one specific embodiment.As shown in Figure 3, illuminated keyboard 3 comprises a plurality of key-press modules 32.Key-press module 32 usefulness are pushed for the user, and then carry out the function of user institute desire input.
See also Fig. 4 and Fig. 5.Fig. 4 illustrates among Fig. 3 key-press module 32 along the cut-open view of X-X line.Fig. 5 illustrates the exploded view of key-press module 32 among Fig. 4.In this embodiment, key-press module 32 comprises keycap 320, substrate 322, circuit board 324, liftable supporter 326 and elastic component 328.Liftable supporter 326 and elastic component 328 all are arranged between keycap 320 and the substrate 322, wherein, liftable supporter 326 can make keycap 320 relatively substrate 322 move up and down, elastic component 328 then is in order to support keycap 320.
In this embodiment, elastic component 328 is made by rubber or other resilient material.324 of circuit boards are arranged on the substrate 322, wherein, have switch 3240 on the circuit board 324, and switch 3240 can be thin film switch, but also can be other triggering property switches, decide according to practical application.In addition, have the through hole 3224 of corresponding keycap 320 on the substrate 322, can allow light send from substrate 322 belows.
As shown in Figure 5, have first sliding channel 3200 and first snap-in groove 3202 on the keycap 320, and have second sliding channel 3220 and second snap-in groove 3222 on the substrate 322.Liftable supporter 326 comprises first supporting member 3260 and second supporting member 3262, and wherein, first supporting member 3260 and second supporting member 3262 articulate and be the scissors kenel, as shown in Figure 4.
As shown in Figure 5, the definition first side S1 and the second side S2 on first supporting member 3260.The first side S1 has first sliding axle 32600, and the second side S2 has first rotation axis 32602.During assembling, first sliding axle 32600 is mounted slidably in first sliding channel 3200 on keycap 320, and first rotation axis 32602 is arranged in second snap-in groove 3222 on the substrate 322 rotationally.In addition, definition the 3rd side S3 and the 4th side S4 on second supporting member 3262.The 3rd side S3 has second rotation axis 32620, and the 4th side S4 has second sliding axle 32622.During assembling, second rotation axis 32620 is arranged in first snap-in groove 3202 on the keycap 320 rotationally, and second sliding axle 32622 is mounted slidably in second sliding channel 3220 on substrate 322.Thus, when keycap 320 was pressed, keycap 320 can be accompanied by liftable supporter 326 relative substrates 322 and move up and down.
As shown in Figure 4, light guide plate 42 is arranged on substrate 322 belows of key-press module 32.Light guide plate 42 comprises main body 420 and reflecting part 422.White light source 40 is arranged on main body 420 places of contiguous light guide plate 42.422 of reflecting parts are the bottoms 4200 that is printed on main body 420.In this embodiment, white light source 40 can be white light emitting diode, but not as limit.The main body 420 of light guide plate 42 can be by acryl (acrylic), polycarbonate resin (polycarbonate, PC), (acrylonitrile-butadiene-atyrene ABS) waits the material of tool transparent nature to make to acrylonitrile-butadiene-styrene copolymer.
See also Fig. 6.Fig. 6 illustrates the upward view of white light source among Fig. 5 40 and light guide plate 42.As shown in Figure 6, reflecting part 422 is being arranged then comparatively sparse comparatively intensive near the arrangement of white light source 40 places away from white light source 40 places.Thus, the light that sends from white light source 40 can be reflected by the reflecting part on the light guide plate 42 422 fifty-fifty, and does not have the situation generation that light and shade differs.
In this embodiment because employed light source is white light source, the utility model promptly with the different ink printing of color and white light source 40 in the bottom 4200 of light guide plate 42, as above-mentioned reflecting part 422.After light that white light source 40 sends is via reflecting part 422 reflections, can send light with reflecting part 422 same colors.
For example, if at the bottom of light guide plate 42 4200 printing blue color inks, then the light that sent of white light source 40 can reflect blue ray via blue ink; If at the bottom 4200 of light guide plate 42 printing red inks, then the light that sent of white light source 40 can reflect red light via red ink; By that analogy.Thus, under the prerequisite that need not change light source, change that just can be by reflecting part 422 colors makes white light source 40 send light with the printing-ink same color via light guide plate 42.
See also Fig. 7.Fig. 7 illustrate light guide plate 42 according to another specific embodiment of the utility model ' synoptic diagram.Light guide plate 42 ' be light guide plate 42 ' go up except that being printed with reflecting part 422 still to be printed with another reflecting part 424 with the main difference part of above-mentioned light guide plate 42.For example, if reflecting part 422 be blue ink, and reflecting part 424 be red ink, then after light that white light source 40 sends reflects respectively via reflecting part 422 and reflecting part 424, can send the light of blueness and redness simultaneously.In other words, the utility model only needs the versicolor printing ink of printing on light guide plate, gets final product the light color that any conversion is desired to send, and need not change light source.
See also Fig. 8 and Fig. 9.Fig. 8 illustrates the cut-open view according to the key-press module 52 of another specific embodiment of the utility model.Fig. 9 illustrates the upward view of non-white light source 60 and light guide plate 62 among Fig. 8.Be noted that the structural design of key-press module 52 is all identical haply with key-press module 32 among Fig. 4, does not repeat them here.
As shown in Figure 8, light guide plate 62 comprises main body 620 and reflecting part 622.Non-white light source 60 is arranged on main body 620 places of contiguous light guide plate 62.622 of reflecting parts are the bottoms 6200 that is printed on main body 620.In this embodiment, non-white light source 60 can be non-white light emitting diode, but not as limit.The main body 620 of light guide plate 62 can be made by the material of acryl (acrylic), polycarbonate resin (PC), acrylonitrile-butadiene-styrene copolymer tool transparent nature such as (ABS).
In this embodiment because employed light source is non-white light source, the utility model promptly with the identical ink printing of color and non-white light source 60 in the bottom 6200 of light guide plate 62, as above-mentioned reflecting part 622.After light that non-white light source 60 sends is via reflecting part 622 reflections, can strengthen illumination effect effectively.In other words, the ink colors of reflecting part 622 can be done conversion along with the color of non-white light source 60, makes illumination effect more remarkable.
Be compared to background technology, according to LGP of the present utility model, if light source is white light source, The utility model namely with the different ink printing of color and white light source in the bottom of LGP, as above-mentioned Reflecting part. Thus, under the prerequisite that need not change light source, just can pass through the change of reflecting part color, So that white light source sends light with the printing-ink same color via LGP. If light source is non-white Radiant, the utility model are namely with the end of the color ink printing identical with non-white light source at LGP Section is as above-mentioned reflecting part. Thus, no matter the light that non-white light source sends is any color, All can reflect via the printing ink with same color, and then strengthen illumination effect.
