Abstract
The invention relates to a luminous keyboard. The luminous keyboard comprises a plurality of keys, a thin film circuit board, a luminous element and a lower cover. The lower cover of the luminous keyboard is used for bearing the plurality of keys, the thin film circuit board and the luminous element and has a light guiding effect. In the luminous keyboard, a light guide plate is not additionally arranged, so that the luminous keyboard has the effects of simplifying structure and reducing the thickness of the keyboard.
Description
Technical field
The present invention relates to keyboard, particularly a kind of keyboard with lighting function.
Background technology
Keyboard is the input media that the most generally uses at present, and it can be applied to the electronic equipment that computing machine, personal digital assistant, mobile phone or any needs are provided with the button input.Keyboard except possessing basic function as input interface, for provide the user in the not good environment of illumination still accurately the pressing keys position and the appearance of illuminated keyboard has been arranged avoiding input error.
See also the press-key structure of existing illuminated keyboard shown in Figure 1.This press-key structure comprises a casing 10, a reflecting piece 11, a LGP 12, a film circuit board 13, a plurality of elastic body 14, button 15 and light-emitting component 16.This casing 10 is in order to ccontaining this light-emitting component 16, LGP 12, reflecting piece 11, film circuit board 13, elastic body 14 and button 15.When the user pushed this button 15, this elastic body 14 electrically conducted it because of pressing to this film circuit board 13 of lower compression of button 15.Light-emitting component 16 is arranged at the both sides of LGP 12, injects this LGP 12 in order to light to be provided, and the reflex via reflecting piece 11 transmits this film circuit board 13, elastic body 14 and button 15 with light simultaneously, makes button 15 produce illumination effect.
Can know by said structure, the folded layer by layer structure of establishing of existing illuminated keyboard, very complicated very, and need casing to coat again, and not only cost is high, assembling is time-consuming, and more because of the number of elements of forming, and thickness descends and is difficult for, and can't satisfy the demand of product slimming now.
Summary of the invention
The technical matters that the present invention will solve is, to the above-mentioned deficiency that prior art exists, the illuminated keyboard of a kind of designs simplification and thinner thickness is provided.
The technical solution adopted for the present invention to solve the technical problems provides a kind of illuminated keyboard, and it comprises a plurality of buttons; Be arranged at below these a plurality of buttons and in order to detect the film circuit board of pushing signal of these a plurality of buttons; At least one light-emitting component; And lower cover; This lower cover has corresponding first surface and second surface; This first surface is in order to carry these a plurality of buttons, this film circuit board and this light-emitting component, and this second surface is coated with reflectorised paint, wherein; This lower cover is incident to this first surface with the light that this light-emitting component produced, and reflexes to this a plurality of buttons in this second surface.
This first surface includes a plurality of leaded light points.
Said illuminated keyboard also comprises the elastic body that is arranged between these a plurality of buttons and this film circuit board.
This second surface is a concave surface.
This lower cover is made by the light-permeable plastics.
The lower cover of illuminated keyboard of the present invention is except in order to carry button, film circuit board and the light-emitting component; Also have the effect of leaded light concurrently; Therefore illuminated keyboard of the present invention does not need as existing illuminated keyboard, extra light conducting plate structure to be set, but therefore simplified structure and can reduce the thickness of illuminated keyboard.
Description of drawings
Fig. 1 is the structural representation of existing illuminated keyboard;
Fig. 2 is the illuminated keyboard structural representation of preferred embodiment of the present invention;
Fig. 3 is the partial enlarged drawing of Fig. 2.
Embodiment
The present invention proposes a kind of illuminated keyboard, and through lower cover is combined light-guiding function, to simplify member, reduction keyboard thickness solves the puzzlement that prior art is brought.
See also Fig. 2 and Fig. 3, Fig. 2 is the structural representation of the preferred embodiment of illuminated keyboard of the present invention, and Fig. 3 is the partial enlarged drawing of Fig. 2.As shown in Figure 2, this illuminated keyboard 2 comprises a plurality of button 21, a plurality of elastic body 25, film circuit board 22, light-emitting component 23 and lower cover 24.Elastic body 25 is arranged at respectively between button 21 and the film circuit board 22; Lower cover 24 is made by the light-permeable plastics; Comprise first surface 241 and second surface 242; This light-emitting component 23 is arranged at the both sides of this lower cover 24, and this lower cover 24 is arranged at the bottom of illuminated keyboard 2, and the first surface 241 of this lower cover 24 is in order to carry above-mentioned button 21, elastic body 25, film circuit board 22 and light-emitting component 23.Preferably, but non-in order to the restriction the present invention, the first surface 241 of lower cover 24 is provided with a plurality of leaded light points 244, with so that light evenly disperse.In addition, the second surface 242 of this lower cover 24 is a concave surface, and is coated with one deck reflectorised paint 243.
Please, when user's pressing keys 21 is also oppressed this elastic body 25 simultaneously, can oppress this film circuit board 22 simultaneously it is electrically conducted with reference to Fig. 3.This light-emitting component 23 provides the first surface 241 of irradiate light to this lower cover 24.Because lower cover 24 is that made and its second surface 242 is coated with reflectorised paint 243 by the light-permeable plastics; Therefore the light that is incident to the first surface 241 of lower cover 24 will penetrate lower cover 24 and reach second surface 242 and upwards reflex to a plurality of leaded light points 244 so that light penetrates this film circuit board 22, elastic body 25 and button 21 after evenly dispersing by reflectorised paint 243; Make button 21 produce illumination effect; Let the user in the not good environment of illumination, still accurately pressing keys position and unlikely input error.
Because the lower cover 24 of illuminated keyboard of the present invention is except in order to carry button 21, film circuit board 22 and the light-emitting component 23; Also have the effect of leaded light concurrently; Therefore illuminated keyboard of the present invention does not need as existing illuminated keyboard, extra light conducting plate structure to be set, but therefore simplified structure and can reduce the thickness of illuminated keyboard.
The above is merely preferred embodiment of the present invention, is not in order to limiting claim scope of the present invention, and therefore all other do not break away from the equivalence of being accomplished under the disclosed spirit and change or modify, and all should be contained in the claim scope of the present invention.
