Abstract
Disclosed is a keyboard with an aphototropism framework. A bridge plate under the keyboard through the aphototropism framework and an optical conduction space generated by the bottom board refacts the light conducting part into the optical conduction space and passing through the bridge plate in corresponding to the keyboard towards the optical conduction space to lighten the keyboard thereby reducing the cost and centralizing the light to the keyboard avoiding light missing of the whole keyboard.
Description
Technical field
The utility model relates to a kind of keyboard that possesses framework backlight, especially relate to a kind of can be by below keypad portion, being provided with to the framework backlight of keypad portion transmitting illuminant.
Background technology
No matter be desktop PC, laptop computer, mobile computer, or the employed keyboard of Web TV, can under low-light level or dark surrounds, can see keyboard clearly and convenient ability of knocking keyboard in order to provide a kind of, existing multiple illuminated keyboard patent is come out, for example United States Patent (USP) the 6284988th, 6322229,6199996,6554442, No. 6179432 and Taiwan announce the 509955th, 465777,535385,438035,570235,468833, No. 516671, all mention and a kind ofly utilize built-in light tiles outwards to penetrate light source, thereby allow the user can clearly judge the keyboard beating position.
But, in above-mentioned each patented technology document, can seek out its common ground, in each patented technology document, all seek only to have between luminescence component in the keyboard and the keycap touch part and interlinked mechanism to intercept, and mostly keycap, touch part and interlinked mechanism are made (partial monopoly be keycap is designed to non-light transmissive material but character symbols on the keycap is that light transmissive material is made) with light transmissive material in each patent, when allowing the luminescence component full slice system penetrate light source, keyboard is to present even kenel backlight, but this kind light-emitting mode causes the user to perplex on the contrary, now is described as follows:
Because the user mostly is insufficient light at the environment of operating light-emitting keyboard, comparatively dark place, for example on the aircraft, the first-class low-light level environment of car, but keyboard full wafer uniformly light-emitting, to cause overall brightness to cross by force and other people around the influence, and in this low-light level environment, the user originally just reduces many to the visual capabilities of keyboard, if full wafer is evenly shinny, the user is difficult to the character symbols on each keycap of identification at all, even this character symbols is made with light-proof material, perhaps keycap is a light-proof material and character symbols is a light transmissive material, the degree of difficulty that all can cause identification to be difficult for because of light source disturbing effect emitted between the adjacent keycap, can't remember keycap character symbols person really to being unfamiliar with, will often produce and knock mistake and the output error instruction signal.
The utility model content
Fundamental purpose of the present utility model is to solve the defective that exists in the above-mentioned prior art, and for avoiding the existence of this defective, the utility model provides a kind of keyboard that possesses framework backlight.
For this reason, according to the keyboard that possesses framework backlight of the present utility model, the component units that it is characterized in that keyboard from top to bottom includes: a keypad portion, be made up of a plurality of buttons, button includes keycap and that a surface possesses symbol and connects and establish keycap and provide keycap to push the interlinked mechanism of displacement stroke; One bridge plate, another termination that supplies interlinked mechanism is if the relative bridge plate of keypad portion is pushed displacement; One signal triggering component includes a circuit board and and pushed to touch the touch part of circuit board output signal by keypad portion; Wherein, the bridge plate below also disposes a base plate, then define light source conduction space between base plate and the bridge plate, and on the corresponding keypad portion of bridge plate, desire to send the light source place and be provided with at least one light guide section to light source conduction space, enter the transmitting illuminant in the light source conduction space and be directed into keypad portion with the light guide section reception, thereby constitute the framework backlight of keyboard.
Another purpose of the present utility model is that light guide section can make with bridge plate one ejection formation, and bridge plate or base plate all can be provided with the light source plane of refraction.
Thus, adopt the keyboard that possesses framework backlight of the present utility model, can concentrate light source to keypad portion to show and avoid whole the defective that keypad portion is luminous, and can effectively limit that keypad portion is actual desires to send the light source scope according to light guide section design attitude and size.In addition, utilize the light source plane of refraction also can improve the brightness effects of transmitting illuminant, reduce the light source assembly design and reduce framework cost backlight.
