Detailed description of the invention
Below in conjunction with the accompanying drawings the technical solution of the utility model is described further.
As shown in Figure 1, traditional backlight keyboard is typically made up of the keycap 1 arranged from top to bottom, shears 3, elastomer 5, conducting wire plate 4, base plate 2 and backlight module 6, backlight module 6 is fitted in below the base plate 2 of keyboard, the assembling of backlight keyboard is cumbersome, and, base plate 2 needs arrange many places holes, so that the light that backlight module 6 provides is transferred on keycap 1, on the one hand complex process, on the other hand base plate many places holes can be greatly reduced the intensity of keyboard.
As shown in Figures 2 and 3, backlight keyboard construction of the present utility model, including keycap 1 and base plate 2, coupled by shears 3 between keycap 1 and base plate 2.Being provided with elastomer 5 and conducting wire plate 4 between keycap 1 and base plate 2, elastomer 5 is used for supporting keycap 1, and by being transferred on conducting wire plate 4 by amount of pressure on keycap 1, makes line conduction.Backlight module 6 it is provided with between conducting wire plate 4 and base plate 2.
Lower snap fit 201 can be provided with on a base plate 2, being provided with upper clamping hook 101 bottom keycap 1, shears 3 includes scissor 301, lower scissors foot 302 and central shaft hole, as shown in fig. 4 a, upper scissor 301 couples with upper clamping hook 101, and lower scissors foot 302 couples through backlight module 6 with lower snap fit 201.Such as Fig. 3, before assembling, shears 3 is the double-deck tabular with central shaft hole；During assembling, elastomer 5 is through the central shaft hole of shears 3, the upper scissor 301 and the lower scissors foot 302 that make shears 3 are opened, elastomer 5 is fixed in the central shaft hole of shears 3, when pressing keycap, elastomer 5 pressurized, drives lower scissors foot 302 to deviate from from the snap fit of base plate 2 upper surface, and lower scissors foot 302 is horizontally slipped by elastic force surface on a base plate 2；As shown in Figure 4 b, press degree is different, and elastomer 5 compression degree is different, its elastic force produced so that lower scissors foot 302 can also slide at any layer body structure surface of backlight module 6 upper surface or backlight module 6.
As shown in figure 5a and 5b, backlight module 6 includes light emitting diode 7, light guide plate 8 and FPC wiring board 9, and light emitting diode 7 is connected with FPC wiring board 9, it is provided that light source, the light that light emitting diode 7 sends enters light guide plate 8, the light guiding points 10 of light guide plate 8 reflexed to keycap 1.As shown in Figure 5 a, FPC wiring board 9 may be located at the lower section of light emitting diode 7, and as shown in Figure 5 b, it can also be positioned at the top of light emitting diode 7.
Reflector plate 12 can be set below light guide plate 8, it is also possible to is covered with reflective ink at light guide plate 8 lower surface.Assemble some astigmatism by reflector plate 12 or reflective ink, and reflexed to keycap, it is achieved the recycling of light source, it is possible to improve keypad brightness further.
Brake sack 11 can also be provided above at light guide plate 8, or be covered with black out ink at light guide plate 8 lower surface.Brake sack 11 can be located at below conducting wire plate 4 or is integrated in the random layer within conducting wire plate 4, can be by removing remaining position printing-ink of corresponding keycap 1 on brake sack 11 surface, the light through light guide plate 8 reflection is made only to pass through keycap 1, focus utilization light source, makes the illumination effect of keyboard become apparent from.Stop owing to the some light of light guide plate 8 transmission is blocked sheet 11, returns light guide plate 8, light guiding points 10 on light guide plate 8 is re-emitted into keycap 1, realize the recycling of light, therefore, the function of reflector plate can be replaced by the part of brake sack 11 printing-ink, so can reduce the thickness of backlight keyboard.
Backlight module 6 is arranged on above base plate 2 by this utility model, and light directly sends from backlight module 6 front, is irradiated on keycap 1 through the hole on conducting wire plate 4 or conducting wire plate 4 so that surface of keyboard is luminous.More traditional backlight keyboard, the utilization of light source is simpler, and more directly, and the bulk strength of keyboard is more preferable.Meanwhile, backlight can keep consistent in shape with the keyboard of non-backlight, and the assembling to system is more favourable.
