Description
Technical field
The present invention relates to the field of keyboard more particularly to a kind of keyboards with lighting function.
Background technology
In recent years, since the information industry development is rapid, many users may use portable information under various circumstances
Device, such as laptop, mobile phone or personal digital assistant etc..In the weaker environment of light, user may not see Chu
The number and word indicated on keyboard, thus cause operation difficult, severe patient possibly even because recognizing button reluctantly
It indicates and allows visual impairment.Therefore, the release of illuminated keyboard can improve the inconvenience that user uses keyboard at insufficient light.
What is more, by different luminous configurations, the massaging device using illuminated keyboard can be enabled to seem more aesthetically pleasing, and then increase it
Market.In addition, based on the demand on particular professional, as electricity it is competing on the keyboard (gamepad) that uses, using same color or not
The button indicated on keyboard with the light of color can be that user brings more preferably manipulation experience.
~Fig. 3 is please referred to Fig.1, Fig. 1 is the structural side view of existing illuminated keyboard, and Fig. 2 is the thin of illuminated keyboard shown in Fig. 1
The stereogram exploded view of film wiring board, Fig. 3 are the keycap perspective exploded view of illuminated keyboard shown in Fig. 1.Illuminated keyboard shown in Fig. 1
1 be applied to demand of specialty, such as play demand comprising metal key-press bottom plate 13, film circuit board 14, multiple press-key structures 15 with
And a plurality of light-emitting elements 16, and film circuit board 14 is including lower plywood 141, top plate 142 and between lower plywood 141 and upper layer
Middle plate 143 between plate 142；Wherein, lower plywood 141 has by multiple elargol circuits 14111 and 14112 institute of multiple lower contacts
First circuit pattern 1411 of composition, and top plate 142 has by multiple elargol circuits 14211 and 14212 institute of multiple upper contacts
The second circuit pattern 1421 of composition, in addition, middle plate 143, which has, corresponds to multiple lower contacts 14112 and multiple upper contacts
14212 contact trepanning 1431, wherein the corresponding lower contact 14112 of each upper contact 14212 is collectively formed a film and opens
Close 144.
In addition, metal key-press bottom plate 13 is set to the lower section of film circuit board 14, connected with for multiple press-key structures 15
Thereon, multiple press-key structures 15 are respectively arranged at 144 place of corresponding multiple thin film switches, and each press-key structure 15 all has
There are keycap 151, connecting element 153 and elastomer 152, wherein each connecting element 153 is connected to corresponding keycap 151
And between metal key-press bottom plate 13, and to make keycap 151 that can be moved up and down relative to film circuit board 14, and each elasticity
Body 152 is then set between corresponding keycap 151 and film circuit board 14, and has a top 1521.
It is past to move down when moving down relative to film circuit board 14 when the keycap 151 of any press-key structure 15 is touched
Dynamic keycap 151 can squeeze elastomer 152, so that the top 1521 of elastomer 152 is supported corresponding on film circuit board 14
Upper contact 14212, so make corresponding upper contact 14212 contacted via corresponding contact trepanning 1431 it is corresponding under
Thus contact 14112 enables corresponding thin film switch 144 reach and electrically conducts, so that the generation one of film circuit board 14 is corresponding
Push button signalling.And when the keycap of press-key structure 155 151 is no longer touched, keycap 151 can be in response to the elasticity of elastomer 152
Power and up move and set back relative to film circuit board 14.
Furthermore a plurality of light-emitting elements 16 correspond to multiple press-key structures 15 and are arranged respectively, that is, each press-key structure
15 lower section is all configured with a light-emitting component 16, therefore 16 provided light beam L1 of each light-emitting component can be pressed directly toward corresponding
The keycap 151 of bond structure 15 projects, and is exported outward from multiple transmittance sections 1511~1514 of keycap 151 in turn, to generate hair
Light effect.
However, the shortcomings that existing illuminated keyboard 1 is, it is limited to the connecting element 153 and bullet of each press-key structure 15
The position of property body 152, corresponding light-emitting component 16 are only capable of being positioned away from the position at the center of press-key structure 15,
But such deviation design will make the illumination effect of corresponding keycap 151 uneven.For example, if light-emitting component 16 is setting
Underface in the transmittance section of corresponding keycap 151 1511~1512, then compared to transmittance section 1513~1514, transmittance section
1511~1512 can seem especially bright.Therefore, existing illuminated keyboard has improved space.
