Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
The purpose of this utility model is under the condition that does not increase backlight module volume or keyboard gross thickness, and the illuminated keyboard of further lifting button brightness effects is provided.
Feature of the present utility model is that base plate at key-press module is in conjunction with leaded light post or reflecting pole, and utilize this leaded light post or reflecting pole to link fixing assembly as key-press module and backlight module, thus, utilize the leaded light post with light refraction in the light guide plate and/or reflection, or utilize reflecting pole that light is reflected, to make full use of the light quantity that the light increase penetrates button, promote the brightness effects of button.
Technological means of the present utility model provides a backlight module and at least one key-press module with light guide plate, this key-press module is located at the exiting surface position of backlight module, light guide plate is provided with plurality of through holes, key-press module has a base plate, this base plate is provided with plural leaded light post or reflecting pole, and this leaded light post or reflecting pole pass the perforation of light guide plate and fix.
As a kind of selection, described leaded light post is transparent material and has the character of refraction and/or reflection ray.
Select as another kind, at least one surface of described leaded light post can also be provided with reflective material, further improves the efficient from leaded light post reflection ray, and this reflective material can be light-permeable or light-permeable not.
As another selection, described base plate and leaded light post are can same material one-body molded.
Select as another, described base plate can adopt different materials to link together respectively with the leaded light post.
The utility model can utilize the material that possesses reflection ray character to make the cylinder that itself has reflective character for the technological means of described reflecting pole, also can reflective material be set in a damaged surface that does not possess reflection ray character.
The utility model can make light can obtain good refraction and/or reflecting effect when projecting the leaded light post and make full use of light, promotes button brightness.
Consult Fig. 1 and shown in Figure 2, a wherein embodiment of the present utility model, include at least one key-press module 1 and at least one backlight module 2, wherein, key-press module 1 has a base plate 11, be provided with plural leaded light post 12 below the base plate 11, button 13 then is set above the base plate 11, be provided with elastic body 14 between button 13 and the base plate 11, elastic body 14 is provided with first conductive part 15, and circuit board 16 then is set on the base plate 11, and circuit board 16 is provided with second conductive part 161 of corresponding first conductive part 15 positions, when button 13 is pressed, can allow elastic body 14 be out of shape simultaneously, cause first conductive part 15 electrically to contact with second conductive part 161.
Leaded light post 12 may have transmittance and refractive index in various degree because of the variance factor of materials used, when lower or refractive index is higher when the transmittance of leaded light post 12, in order to make button obtain to increase the effect of brightness, can be at leaded light post 12 surface combination one deck reflective materials 17 of low-transmittance, to improve the light reflectivity of leaded light post; For example, reflective material 17 can be located at leaded light post 12 as shown in Figure 3A and advance and next surface in the face of light, this reflective material can be light-permeable or light-permeable not, when reflective material is light-permeable, part light is except can being reflected, and another part light then can penetrate reflective material and enter the 12 generation refractions of leaded light post; When reflective material during for light-permeable not, then light is only by reflective material cremasteric reflex effect.
Consult shown in Fig. 3 B, reflective material 17 also can be located at another surface that the lower leaded light post 12 of high transmission rate or refractive index is advanced with respect to light and come, thus, when light produces refraction and/or reflex time by leaded light post 12, the light that part will pass leaded light post 12 originally can reflex to key-press module by reflective material 17, reaches the effect that promotes brightness.
Fig. 4 shows that leaded light post 12 can be replaced by reflecting pole 12A, reflecting pole 12A can utilize the material that possesses reflection ray character to make the cylinder that itself has reflective character, after also can utilizing the material that does not possess reflection ray character to make cylinder, in damaged surface reflective material 17 is set again.
Aforementioned reflective material 17 also can utilize color to have the characteristic of reflection ray and color is incorporated into damaged surface and form reflecting pole except the material behavior that can pass through this reflective material itself obtains the reflecting effect; For example, light color has preferable reflective character with respect to dead color, therefore, can with white, gold, silver color ... wait pigment to be incorporated into damaged surface and obtain preferable reflecting effect.
Described backlight module 2 is to be arranged at key-press module 1 below, and this backlight module 2 includes a light guide plate 21, and the light source 23 of being located at the light guide plate side, and in preferred embodiment of the present utility model, described light source is to adopt light emitting diode (LED).Light guide plate 21 is provided with the perforation 22 of described leaded light post 12 of a plurality of correspondences or reflecting pole 12A position, and is provided with in the bottom surface of light guide plate 21 and can reflects and/or the optical texture 24 of refracted ray; Described optical texture can be tiny prominent grain or shrinkage pool, or is printed on the point-like figure of bottom surface of light guide plate.
The array mode of key-press module 1 and backlight module 2, be after being incorporated into the leaded light post 12 of key-press module 1 or perforation 22 that reflecting pole 12A passes light guide plate 21, again the end of leaded light post 12 or reflecting pole 12A is shaped to the head 121 of expansion, to stop leaded light post 12 or reflecting pole 12A to break away from light guide plate 21, reach key-press module 1 and link fixing purpose with backlight module 2.
By aforementioned structure of the present utility model, after the light that light source 23 produces entered light guide plate 21 conduction, part light can pass base plate 11 and button 13 via optical texture 24 reflections and/or refraction, makes button 13 produce illumination effects; Part light is after being projected to leaded light post 12 or reflecting pole 12A, and then leaded light post 12 can penetrate light refraction and reflection from button 13, makes the brightness of button 13 obtain to promote.
Consult shown in Figure 4ly, when replacing leaded light post 12 with reflecting pole 12A, can be reflected material 17 or reflecting pole 12A reflection itself of the light that then is projected to reflecting pole 12A passes from button, also can reach the effect of lifting button brightness.
The above only is in order to explain the preferred embodiment of the utility model; be not that attempt is done any formal restriction to the utility model according to this; so all have in following relevant any modification or the change done of identical spirit, all must be included in the protection category of the utility model claim.
