Description

Be convenient to distinguish the illuminated keyboard of key position

Technical field

The utility model relates to a kind of illuminated keyboard, relates in particular to a kind of difference of luminosity of passing through so that the illuminated keyboard of differentiation key position.

Background technology

In epoch of scientific and technological information now, computer has become the indispensable necessity of people, and it is closely bound up with people's life, all trades and professions also all need rely on computer to come less important work, no matter be desktop PC or mobile computer etc., the field of its use and opportunity are quite extensive, and all might use in any environment, but under low-light level or dark surrounds, because insufficient light causes accurately knocking the signal output of keyboard, be head it off, existing multiple at present illuminated keyboard patent is come out, as the U.S. the 6179432nd, 6199996,6284988,6322229, shown in No. 6554442 patent cases, above-mentioned patent case all discloses a kind of illuminated keyboard, mainly a light tiles is arranged at keyboard, makes light tiles luminous and be convenient to user's operation keyboard in insufficient light or dark environment keycap.

But, require all in above-mentioned each patented technology document that only flexible body and interlinked mechanism intercept between light-emitting component in the keyboard and the keycap, and in each patent mostly with keycap, elastomer and interlinked mechanism make with light transmissive material that (partial monopoly is that keycap is designed to non-light transmissive material, but the character symbols on the keycap is a light transmissive material to be made), when allowing the light tiles full slice system penetrate light source, keyboard presents even form backlight, 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 keyboard visual capabilities, 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, also can cause the difficult difficulty of identification because of the emitted light source disturbing effect in the gap of adjacent keycap, can't remember keycap character symbols person really to being unfamiliar with, generation is knocked mistake and the problem of output error command signal.

The utility model content

Main purpose of the present utility model is to solve the aforesaid drawbacks, and makes button different with the brightness in gap, to distinguish the relevant position of button and button.

For reaching above-mentioned purpose, the utility model proposes a kind of illuminated keyboard of being convenient to distinguish key position, it comprises a keypad portion and an illuminating part, wherein, this keypad portion has a substrate and is positioned at multiple row keycap on the substrate, is provided with a plurality of interlinked mechanisms that link keycap and substrate between keycap and the substrate, and keycap is moved up and down by the relative substrate of interlinked mechanism, and the keycap of adjacent column has first gap, and adjacent keycap has second gap in each row; And this illuminating part is arranged between these keycaps and this substrate, and is provided with a plurality of first luminescence segments corresponding to first gap, and corresponding to a plurality of second luminescence segments in second gap, and the second luminescence segment two ends link two first adjacent luminescence segments.

By this first, second luminescence segment, make the keycap on this illuminated keyboard different with the brightness in keycap first, second gap all around, so that distinguish the position of each keycap, knock the accuracy of input with lifting.
