Description
Technical field
The present invention relates to a kind of keyboard, relate in particular to a kind of keyboard with lighting function.
Background technology
In recent years, because the information industry development is rapid, many users may use portable massaging device, such as notebook computer, mobile phone or personal digital assistant etc. under varying environment.At the weak environment of light, user may not see the numeral and the word that on Chu's keyboard, indicate, thereby causes operational difficulty, and severe patient even may allow visual impairment because identification button reluctantly indicates.Therefore, the release of illuminated keyboard can improve user in the inconvenience of insufficient light place use keyboard.What is more, by different luminous configurations, can make and use the massaging device of illuminated keyboard to seem more attractive in appearance, and then increase its market.
Refer to Fig. 1, the structural profile schematic diagram that it is existing illuminated keyboard.Illuminated keyboard 1 comprises reflector 11, light guide plate 12, supporting bracket 13, film circuit board 14, multiple button 15 and side direction type illuminating element 16, wherein, film circuit board 14 comprises lower plywood 141, top plate 142 and the la m between lower plywood and top plate 143, and lower plywood 141, la m 143 and top plate 142 are all made by transparent light guide material, transparent light guide material can be Merlon (PC) or polyethylene (PET) etc.
Moreover, please synchronously consult Fig. 2, it is the three-dimensional exploded view of the film circuit board of illuminated keyboard shown in Fig. 1, lower plywood 141 has the first circuit pattern 1411 being made up of multiple elargol circuits 14111 and multiple lower contacts 14112, and top plate 142 has the second circuit pattern 1421 being made up of multiple elargol circuits 14211 and multiple upper contacts 14212, again, la m 143 has the contact perforate 1431 with multiple upper contacts 14212 corresponding to multiple lower contacts 14122, wherein, common shape one thin film switch 144 of lower contact 14112 that each upper contact 14212 is corresponding with it.
Again, supporting bracket 13 is arranged at the below of film circuit board 14, and has multiple perforation 131, first fixed structure 132 and the second fixed structure 133; And each button 15 comprises keycap 151, elastomer 152 and scissor Connection Element 153, and keycap 151 comprises the first keycap fixed structure 1511 and the second keycap fixed structure 1512; And scissor Connection Element 153 comprises the first framework 1531 and the second framework 1532; In addition, elastomer 152 is between keycap 151 and film circuit board 141.
Wherein, film circuit board 14 has the open-work 145 and the open-work 146 that supply respectively first fixed structure 132 and the second fixed structure 133 to pass wherein, can be connected in the second fixed structure 133 for one end 15311 of the first framework 1531, and its other end 15312 can be connected in the first keycap fixed structure 1511, and can be connected in first fixed structure 132 for one end 15321 of the second framework 1532, and its other end 15322 can be connected in the second keycap fixed structure 1512.
When arbitrary button 15 touched and while moving down with respect to supporting bracket 13, the first framework 1531 and second framework 1532 of scissor Connection Element 153 change to closed state by folding condition, and the keycap 151 moving down can make elastomer 152 support its corresponding upper contact 14212 by extruding elastomer 152, and then make its corresponding upper contact 14212 contact corresponding lower contact 14122 via corresponding contact perforate 1431, make whereby corresponding thin film switch 144 reach and electrically conduct, so that illuminated keyboard 1 produces a corresponding push button signalling.And in the time that button 15 is no longer touched, keycap 151 can up move with respect to supporting bracket 13 in response to the elastic force of elastomer 152, now the first framework 1531 and the second framework 1532 change to folding condition by closed state, and keycap 151 can set back.
Moreover side direction type illuminating element 16 is arranged at the side of light guide plate 12, in order to provide light beam to inject light guide plate 12.And light guide plate 12 is arranged on reflector 11, and its lower surface has the multiple light guiding points 121 in order to gathering and scattered beam.Multiple light guiding points 121 are set up according to the position of corresponding multiple buttons 15.Wherein, in the time that light beam is injected light guide plate 12, light beam is flooded to whole light guide plate 12, and multiple light guiding points 121 can because of its relation for ink material by light beam up and down scattering, up the light beam of scattering can sequentially be projected to multiple buttons 15 by multiple perforation 131 and the film circuit board 14 of supporting bracket 13, and down the light beam of scattering can upwards reflect light beam via the auxiliary of reflector 11 again, so that can being improved, the light beam that side direction type illuminating element 16 provides utilizes.As mentioned above, can make multiple buttons 15 produce luminous effect.Only, existing illuminated keyboard 1 has shortcoming as described below:
Although a reflector 11 can assist the light beam of multiple light guiding points 121 downward scatterings to reflect upward, but the material of the reflector 11 of existing illuminated keyboard 1 still can allow a little light beam penetrate, therefore a part can penetrate reflector 11 by the light beam of multiple light guiding points 121 downward scatterings and cause the loss of light quantity.
Although can be flooded to whole light guide plate 12 when two light beams are injected light guide plate 12, but because the light guiding points 121 nearer apart from side direction type illuminating element 16 reflects segment beam outside light guide plate 12, make the light quantity in light guide plate 12 middle distance side direction type illuminating elements 16 region far away not as coming sufficiently in the region nearer apart from side direction type illuminating element 16.
Three, because the running stroke of scissor Connection Element 153 is longer, therefore must having enough spaces, illuminated keyboard 1 can make scissor Connection Element 153 normal operations, but but therefore cannot effectively reduce the thickness of illuminated keyboard 1, to such an extent as to cannot meet now electronic product towards external form demand light, thin, short and small development.
Explanation for above-mentioned first and second point is known, although existing illuminated keyboard 1 is to see through the cooperation of side direction type illuminating element 16 and light guide plate 12 and make multiple buttons 15 produce luminous effect, efficiency of light is not good.Base this, how improve under the thinking of efficiency of light, attempt substituting side direction type illuminating element 16 with straight-down negative light-emitting component, and make straight-down negative light-emitting component be arranged at the below of button 15, could directly provide light beam to button 15, obtain whereby preferably efficiency of light; But, in such practice, straight-down negative light-emitting component is the below that is positioned at elastomer 152, can hinder the shift motion after elastomer 152 is extruded, therefore just cannot reaching corresponding thin film switch 144 by pressing down keycap 151, user electrically conducts, therefore substitute side direction type illuminating element 16 and directly provide the way of light beam cannot be embodied on existing illuminated keyboard 1 towards button 15 with straight-down negative light-emitting component.
Moreover because above-mentioned thirdly described defect, now existing a kind of capacitor induction type keyboard is suggested, its be in the process being pressed down by keycap, change keyboard circuit board electric field and make circuit board produce the corresponding push button signalling of output one; Wherein, because capacitor induction type keyboard not necessarily will use the related elements such as scissor Connection Element, the integral thickness of capacitor induction type keyboard can effectively be reduced; But, not yet there is now the capacitor induction type keyboard of tool illumination effect to be suggested, therefore under the weak environment of light, user may not see numeral and the word that the button on Chu's capacitor induction type keyboard indicates, thereby causes operational difficulty or visual impairment.
