Technical field

The utility model relates to the keyboard of communication electronic product, relates in particular to a kind of dynamic keyboard of a plurality of light-emitting mode structures.

Background technology

Fast development along with the telecommunications product technology, leaded light device is widely used, the development of product function is according to the needs of surface structure design, and the utility model (as the disclosed light guiding film structure of Chinese patent ZL200720121960.9) on the technical foundation of light guiding film is made more space-efficient keyboard in conjunction with the structural design of product.Light guiding film with the communication product cell phone keyboard is applied as example, develop rapidly with the multifunctional intellectual mobile phone, the markup character design of guiding cell phone keyboard function also more comprehensively, comprise numeric keypad, Qwerty (standard computor-keyboard) keyboard, function keyboard, because of the appearance design of mobile phone is tended to ultra-thin and the small size direction develops, the intelligent function development of cell phone keyboard is subjected to the influence in the space of mobile phone to be restricted can only do more and more littler, the keypad function markup character also can only be done more and more closelyer and be more and more littler, use inconvenient operation to seem also generous inadequately, keyboard pressing operation impersonalityization.

Therefore, how the development need according to communication product cell phone keyboard Multi-Function Keyboard makes keyboard operation meet the design of surface structure hommization, and can design multi-functional intelligence operation keyboard in the restriceted envelope of design is a technical matters that needs to be resolved hurrily in the industry.

The utility model content

The utility model is to solve the technical matters that the multi-functional intelligence operation keyboard of design makes button become more and more closeer also more and more littler after avoiding button to increase in the space that keyboard limits, and provides the light guide sheet of the two-layer at least different spatial of a kind of utilization to make the dynamic keyboard of multimode light guide sheet structure.

For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of dynamic keyboard of multimode light guide sheet structure, comprise semi-transparent plate on shell, the shell, be located at button on the semi-transparent plate, the pattern on the light guide sheet, light guide sheet, provide a plurality of LED of light source to light guide sheet, wherein: comprise at least two not at grade described light guide sheet, the described LED of may command Switching power joins with the incidence surface of each light guide sheet respectively, is respectively arranged with different leaded light patterns on each light guide sheet.

Be provided with the transparent optical cement articulamentum between the described light guide sheet.

Side relative with the LED incidence surface on the described light guide sheet is provided with shading glue.

Movable the sliding of described semi-transparent plate places on the described shell.

One preferred technique scheme: comprised above-mentioned technical characterictic, also include first, second described light guide sheet and respectively with the incidence surface of this first, second light guide sheet first, second described LED that joins, be respectively arranged with different leaded light patterns on described first, second light guide sheet.

Compared with prior art, the utility model can be provided with at least two light guide sheet that include different leaded light patterns respectively on the upright position, the LED that can control Switching power provides light source with the light guide sheet of diverse location respectively, illuminate leaded light pattern on the different light guide sheet by switching LED, also switch the function of leaded light pattern corresponding keys when switching LED, or slide by the activity on shell of semi-transparent plate, the button of keyboard is also moved on another corresponding leaded light pattern, it is luminous simultaneously also to have switched LED, thereby make and to make two or more dynamic keyboard patterns on the same keyboard structure spare, save the structure space of keyboard, combine the led light source control circuit of keyboard, or the button spatial position change of keyboard, the function character functional character that keyboard is shown changes, and has formed the keyboard structure with dynamic sense.

Embodiment

The utility model preferred embodiments, the dynamic keyboard of bimodulus light guide sheet structure as shown in Figure 1, include on shell, the shell fixing semi-transparent plate 1, be located at button 2 on the semi-transparent plate, not at grade first, second

light guide sheet

5,6, respectively with the incidence surface of first, second light guide sheet first,

second LED

7,8 that joins, be respectively arranged with different leaded

light pattern

51,61 on first, second

light guide sheet

5,6, as Fig. 2, shown in Figure 3; First,

second LED

7,8 can control Switching power mutually makes them not luminous simultaneously, be provided with transparent optical cement articulamentum 3 between first, second

light guide sheet

5,6, side relative with the LED incidence surface on the light guide sheet is provided with shading glue 4, be used to prevent the leakage of light, strengthen the brightness of light guide sheet.Also switch the function of leaded light pattern corresponding keys when switching LED in the use, opening a LED 7 while the 2nd LED 8 closes, at the leaded light pattern 51 or the character (as shown in Figure 4) that show on the button 2 on first light guide sheet 5, opening the 2nd LED 8 while the one LED 7 closes, at the leaded light pattern 61 or the character (as shown in Figure 5) that show on the button 2 on second light guide sheet 6, all during the LED power-off, two kinds of mode of operations are closed, do not have demonstration (as shown in Figure 6) on the keyboard, thereby realize the dynamic keyboard of two kinds of pattern light guide sheet structures.Can realize that according to corresponding light source light guide sheet (light guiding film) layering is luminous, be fit to any type of light guide sheet (light guiding film).

The another kind of scheme of the dynamic keyboard of bimodulus light guide sheet structure, include shell, be located on the keyboard case can be up and down or about the movable semi-transparent plate 1 that slides, first, second

light guide sheet

second LED
