Embodiment

Relevant detailed description of the present utility model and technology contents now just cooperate graphic being described as follows:

See also shown in Figure 1, it is the preferred embodiment of the disclosed illuminated keyboard of the utility model, it includes: base plate 10, on this base plate 10, be provided with a plurality of keycaps 11 that can move up and down with respect to base plate 10, between keycap 11 and base plate 10, be equiped with elastomer 12 and suspension gear 13, suspension gear 13 wherein is made up of two first supports 131 intersected with each other and second support 132, the bottom of first support 131 and second support 132 is sticked in the hook part 101 of base plate 10, its top then is movably connected in the bottom surface of keycap 11 (see figure 2), is supporting keycap 11 and elastomer 12 by suspension gear 13.

Between base plate 10 and elastomer 12, also has the luminous circuit board 40 that is integrated with button circuit and luminous element; Wherein the button circuit can be a kind of soft plastic film switch, it is made of three plastic films, middle plastic film 21 is with holes 210 insulation film, the preferred embodiment of undermost plastic film is by a kind of soft electroluminescence plate (EL plate) 22 and be formed at its surperficial lower floor's button circuit 221 and formed, the surface of the plastic film 23 of the superiors then is formed with upper strata button circuit 231, electroluminescence plate (EL plate) the 22nd wherein, required backlight in order to produce, during normality upper strata button circuit 231 and lower floor button circuit 221 then in the hole 210 places apart but do not contact, in case keycap 11 is depressed, the bottom 121 of elastomer 12 will force upper strata button circuit 231 and lower floor's button circuit 221 to contact with each other, cooperate the circuit design of keyboard then and produce electric signal, after external force disappears, just keycap 11 can be pushed back to the position of normality because of the restoring force of elastomer 12.

Elastomer 12 is light-permeable preferably, keycap 11 then can be printing opacity or lighttight design, if keycap 11 is lighttight designs, then the character symbols on it 110 can be the design of printing opacity or directly uses luminescent material (as fluorescent paint) to print, otherwise if keycap 11 is printing opacities, then just be not preferably luminous or the design of light-permeable, so just can possess cognizable effect at its surperficial character symbols 110.

The plastic film 23 of the superiors can be transparent, so that can seeing through, electroluminescence plate (EL plate) 22 provide whole keyboard required backlight, the another kind of feasible embodiment of the plastic film 23 of the superiors then is lighttight design, be transparence only in the position of upper strata button circuit 231, so that it is electroluminescence plate (EL plate) 22 light that sent can upwards expose to the below of keycap 11 via hole 210, a kind of non-comprehensive backlight to produce.

And in another preferred embodiment of Fig. 3, wherein between luminous circuit board 40 and elastomer 12, also be provided with equal tabula rasa 30, this equal tabula rasa 30 can be directed to the scope of whole keyboard equably with electroluminescence plate (EL plate) 22 light that sent, to provide a kind of more uniform backlight; And another feasible embodiment is as shown in Figure 4, wherein be to utilize a kind of bridge plate 60 to carry suspension gear 13 in this embodiment, this bridge plate 60 is to be configured between keycap 11 and the luminous circuit board 40, and this bridge plate 60 is preferably made by the material of light-permeable, also can be designed to be same as the structure of all light function of equal tabula rasa 30.

And then disclosed another kind of feasible preferred embodiment at Fig. 5, wherein between luminous circuit board 40 and elastomer 12, also be provided with lighttight shielding 50, this shielding 50 only has perforation 51 in the position that corresponds to upper strata button circuit 231, so that electroluminescence plate (EL plate) 22 light that sent can upwards expose to the below of keycap 11 via hole 210 and perforation 51, to produce a kind of non-comprehensive (see figure 6) backlight.

Electroluminescence plate in the aforesaid embodiment of the utility model (EL plate) 22 is a kind of with the flexible element of plastic film for its base material except can be, and also can be with the hard electroluminescence plate (EL plate) 22 of glass plate for its base material.

Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
