Fig. 2 and Fig. 3 are please referred to, Fig. 2 is the schematic diagram of the illuminated keyboard of the present invention, and Fig. 3 is the illuminated keyboard of the present invention
Explosive view.As shown in Figure 2 and Figure 3, illuminated keyboard 20 includes the annular shading piece 22 of an at least button 21, one, a barn door 23, one
Switching circuit board 24, a bottom plate 25 and a light source 26.Wherein, each button 21 include a keycap 27, a support component 28 and
One elastomer 29, and annular shading piece 22 includes an opening 221.
Annular shading piece 22, barn door 23, switching circuit board 24, bottom plate 25 and light source 26 are from top to bottom sequentially arranged at key
The lower section of cap 27.Wherein, annular shading piece 22 is located at an inside of button 21 close to one end of button 21 222, to shielding light
One light in source 26, and the opening 221 of annular shading piece 22 to make light by by illuminate button 21.
Annular shading piece 22 can be individual element, can also be formed in barn door 23.Hereafter with annular shading piece 22
It is formed in for barn door 23.Annular shading piece 22 is integrally formed with barn door 23 using identical material or dissimilar material, or
Person, it is first respective to produce annular shading piece 22 and barn door 23, the common fixed form such as adhere, heat, weld is recycled later,
Annular shading piece 22 is fixed on barn door 23.
Switching circuit board 24 is located at the lower section of annular shading piece 22, to generate switching signal.In this preferred embodiment,
Switching circuit board 24 be film switch circuit, and the film of film switch circuit be transparent membrane, therefore light can pass through it is thin
Membrane switch circuit and appear upwards.Bottom plate 25 is located at the lower section of switching circuit board 24, to fixed button 21.
In this preferred embodiment, illuminated keyboard 20 has barn door 23, and barn door 23 can be the deckle board of keyboard, but
It is not limited thereto.In other preferred embodiments, barn door can not also be arranged in illuminated keyboard 20, but utilizes annular shading
Part 22 neighbouring plate replaces barn door.For example, the local surfaces of switching circuit board 24 are coated into impermeable light coating, because
The part of this impermeable light coating has shaded effect, is penetrated for light without the part of impermeable light coating.Thus, switch
Circuit board 24 may replace barn door, and annular shading piece 22 can be also formed on switching circuit board 24.
Light source 26 is set to 21 lower section of button, to illuminate the keycap 27 of button 21.It is pressed since annular shading piece 22 is located at
Between key 21 and light source 26, therefore light caused by light source 26 can be blocked, avoid light from button 21 and another button 21
Between gap in leak out.Annular shading piece 22 can made by light-proof material, such as：Metal can also utilize light transmission
Material coats made by impermeable light coating, such as：Silica gel, wheat draw (Mylar).In this preferred embodiment, barn door 23 is one
Sheet metal generates an at least raised structures first with raising technique on sheet metal, and at the top of each raised structures
It is cut into opening 221, light is enable to illuminate button 21 by opening 221, and these have raised structures of opening 221 then
Form annular shading piece 22.
Element combination and the fixing means of button 21 will be illustrated next.As shown in figure 3, support component 28 is set to keycap 27
Lower section, to support keycap 27.Wherein, one end of support component 28 is connected to the lower surface of keycap 27, and support component 28
The other end then passes through the opening 221 of annular shading piece 22, and then is connected to the hook of bottom plate 25.Therefore, keycap 27 passes through support
Element 28 is fixed on bottom plate 25.In this preferred embodiment, support component 28 is scissor, but is not limited thereto.
Elastomer 29 is located between keycap 27 and switching circuit board 24, to elastic force is provided allow keycap 27 reset.Work as key
When cap 27 is pressed down, elastomer 29 is generated deformation by the pushing of keycap 27 and accumulates elastic energy, and trigger switch circuit board
24 generate switching signal.When keycap 27 is no longer pressed down, elastomer 29 discharges elastic energy, thus drives keycap 27 far from bottom plate
25 return to original position.
Light source 26 is set to 25 lower section of bottom plate, to illuminate button 21.In this preferred embodiment, light source 26 is backlight mould
Block, but be not limited thereto.In other preferred embodiments, light source 26 can be plural LED.Plural LED is set to switch electricity
On road plate 24, and every LED is located at the lower section of each button 21, illuminates each button 21 respectively.
Following light source 26 is by taking backlight module as an example.Light source 26 includes at least one LED 261 and light guide plate 262, wherein LED
261 can be set to the side of light guide plate 262, or be set in the perforation of light guide plate 262.The light that LED 261 is generated is penetrated
After entering light guide plate 262, light will be constantly totally reflected in light guide plate 262, therefore uniform light is distributed in light guide plate 262
In.
Referring to Fig. 4, Fig. 4 is the sectional view of the illuminated keyboard of the present invention.It is led as shown in figure 4, the light of LED 261 enters
After tabula rasa 262, uniform light is distributed in light guide plate 262.When light is by the light guide ink or micro-structure 262a of light guide plate 262
Influence, and when changing the path of light, light leaves light guide plate 262, and is upward through the transmission region of bottom plate 25 (in figure
Do not show).Wherein, the transmission region of bottom plate 25 is loophole, but is not limited thereto.
Later, light moves on, and some light L1 penetrates the switching circuit board 24 of 25 top of bottom plate, and is hidden across annular
After the opening 221 of light part 22, keycap 27 will be arrived at and illuminate button 21.Further, since by annular shading piece 22 and barn door
23 block, and the optical range that goes out of some light L2 is restricted, thus can not between button 21 and another button 21 gap
Middle leakage, thus solve the problems, such as button light leakage.It follows that the height of annular shading piece 22 itself is higher, shut out the light
Effect it is better.
Referring to Fig. 5, Fig. 5 is the pressing schematic diagram of the illuminated keyboard of the present invention.Since annular shading piece 22 has centainly
Highly, keycap 27, which pushes the current situation, will touch annular shading piece 22.As shown in figure 5, when keycap 27 is pressed down, 27 court of keycap
It is moved to bottom plate 25, thus pushes elastomer 29 and annular shading piece 22.
In order to avoid annular shading piece 22 interferes keystroke driving, annular shading piece 22 that can be made using flexible material,
Such as metal, silica gel or wheat are drawn.Since annular shading piece 22 has pliability, when keycap 27 pushes annular shading piece 22
When, annular shading piece 22 generates deformation, and at the end of the stress, annular shading piece 22 can reply for non-stress when shape.
According to the explanation of the above preferred embodiment it is found that the illuminated keyboard of the present invention has annular shading piece.Thus,
Annular shading piece avoids light from being leaked out between button and another button, solves the problems, such as that keycap surrounding generates halation.In addition, working as
When button is pressed down, deformation is will produce by the annular shading piece of button pressed, therefore the pressing stroke of button is not hidden by annular
Light part influences.
The foregoing is merely presently preferred embodiments of the present invention, be not limited to the present invention claim, therefore it is all its
He is intended to be limited solely by the claim of this case without departing from the lower equivalent change or modification completed of spirit disclosed in this invention
It is interior.
