Embodiment
The utility model provides a kind of ultrathin type backlight key panel.Below in conjunction with accompanying drawing to technical solutions of the utility model
It is described in detail, so that it is more readily understood and grasped.
A kind of ultrathin type backlight key panel, as shown in Figure 1 to Figure 3, including the pcb board that order is set from bottom to the top
1st, touch-switch 2, key panel skeleton 3 and superficial layer 4, wherein, touch-switch 2 is arranged at the top surface middle position of pcb board 1,
Light source 5 is provided with positioned at the both sides of touch-switch 2 on pcb board 1, the light source 5 is preferably to be set in LED, and the top surface of pcb board 1
There is the first reflector layer 6, the bottom surface of key panel skeleton 3, which is provided with, is located at second reflector layer 7 of the top of light source 5, and the bottom surface of superficial layer 4 is set
There is the diffusion layer 8 positioned at the top of touch-switch 2.
Wherein, LED is luminescent device, can select the illuminated illuminated LED of LED or side in top, it decides
The characteristic of the optical correlations such as backlight illumination, backlight stability, the backlight color of key panel.
Pcb board 1 is electronic device supporting body, is also the input of the power supply of key panel, is interacted with equipment progress signal
Port, while it also have a certain degree of structural strength.
First and second reflector layer is mainly used in light mixing, and the utilization of reflectorized material is more flexible, can pass through optical software
Simulate to adjust shape size, the material of reflector layer, it is therefore an objective to be irradiated to light is relatively uniform in diffusion layer, then by dissipating
The further mixed light of luminescent material, to reach key panel even back.
Touch-switch 2 is touch-control main body, stable by bonding force size to its requirements of type selecting, to ensure that sense of touch is uniform during button,
Needs determine the touch-switch of long enough service life according to the service life of equipment simultaneously.
The function of diffusion layer 8 is to exhale mixed light with more uniform effect, while having reinforcement table
The effect of surface layer, can also be used as keycap, can select optics plastic material.
Superficial layer 4 is key panel most top layer, can use optical filtering minute surface, to realize the function of regulation glow color.
Key panel skeleton 3 is the critical piece of key panel structure intensity, is the accole of other all parts, it determines
Determine the geomery of backlight key panel, while the function of coordinating with the other parts of equipment is undertaken, or even can be by adjusting it
Structure directly serves as outer layer panel.
More refinement ground description, key panel skeleton 3 is provided with through hole 31, and diffusion layer 8 is located in through hole 31, and diffusion layer
8 surrounding has gap 9 with through hole 31.Wherein, diffusion layer 8 is provided with the key legend 10 of hollow out.Opened when key panel is in
When opening state, as shown in figure 4, wherein slanted bar type dash area is highlight area, horizontal stripe type dash area is sheen region.
In addition, for increase sense of touch, touch-control end and the diffusion layer 8 of touch-switch 2 are abutted against, and add the stationarity of touch-control,
With preferably Consumer's Experience.
Finally, the first reflector layer 6 is the reflecting coating being coated on the top surface of pcb board.Second reflector layer 7 is to be fixedly installed
Reflector in key panel skeleton bottom surface.
This case employs modularized design, will carry the pcb board of LED, key panel skeleton, touch-switch, surface
Layer organic integration is an entirety, can be directly embedded among device panel structural member when in use, or by adjusting button
The structure of panel skeleton and the panel that directly serves as equipment are used.Technically, pcb board, key panel skeleton, table are utilized
Surface layer will need the region of backlight to form the space of multiple relative closures, while reflector layer and diffusion layer are organically combined, to these
Light in the space of closing carries out mixed light processing, then is appeared mixed uniformly light by superficial layer, to realize that backlight is imitated
Really.The use of touch-switch can make key panel obtain more stable, uniform sense of touch.
, can be with accurate simulation mixed light path and light mixing effect with optical simulation software, can so as to be easily achieved backlight
Control, it is to avoid each sample of conventional keys panel makes, and can greatly save product development cost and time.Meanwhile, button
Corresponding internal structural space is mixed light area, while being also LED, the place space of touch-switch, this confined space
Multiplexing be a key point for realizing ultrathin and flexibility because using this pattern can realize variously-shaped size by
The backlight of key.The size in the plate thickness direction of this case key panel can be controlled within 5mm.
By above description it can be found that the backlight of key panel of the present utility model is controllable, backlight stable and uniform；It is ultra-thin
Characteristic be easy to key panel to install, to install control demand it is low；The sense of touch of key panel is uniform, improves Consumer's Experience.
Above the technical solution of the utility model fully describe, it is necessary to explanation is, tool of the present utility model
Body embodiment is simultaneously not limited by the description set out above, and one of ordinary skill in the art exists according to Spirit Essence of the present utility model
Using all technical schemes formed by equivalents or equivalent transformation in terms of structure, method or function, this reality is all fallen within
Within new protection domain.
