The operation comfort and convenience of button, operation of the people to touch controlled key is also set to propose higher requirement.
On the one hand, whether physical entity button, touch-control virtual key either touch-control physical button enter in user to it
During row operation, used due to consideration that user can wait at night under the scene for not seeing Chu, often send backlight and cause user
Can see the physical entity button, touch-control virtual key either touch-control physical button be specifically in terminal which by
Key, the problem of from without pressing by mistake.On the other hand, it is such to be not as physical entity button for touch controlled key, during operation, has
Mechanical Touch feeds back, and touch controlled key is one of conventional means by light feedback, is especially used on medical display, equipment
Feedback mechanism be to ensure the indispensable design method of doctor's adjusting device.
But the backlight function of these buttons is limited to that it has to light emitting diode and light guide structure is implemented in combination with present,
But people excessively consider the thickness of stripping apparatus in most cases, unobvious are improved to backlight uniformity, have impact on operator couple
The side vision perceived effect of button, especially to professional equipment, such as medical display.
Utility model content
Technical problem to be solved in the utility model is the defects of overcoming prior art, there is provided a kind of even back enhancing
Type touch controlled key component, by the rational design to light emitting diode and light guide structure, on the premise of touch-control effect is not influenceed,
Strengthen the backlight uniformity of touch controlled key.
To reach above-mentioned purpose, the utility model provides a kind of enhanced touch controlled key component of even back, including PCB1
Plate, light guide plate, cover-plate glass, connector, several LEDs and PCB2 plates；It is the cover-plate glass, the light guide plate, described

PCB1 plates, several described LEDs are equidistantly fixedly installed on the PCB1 plates upper surface, several are opened up on the PCB2 plates
Coordinate the through hole of the LED.
Preferentially, the connector includes two bolts and two hex nuts, and two bolts are symmetrically fixedly connected
The PCB2 plates lower surface, a hex nut is threadedly coupled on each bolt.
Preferentially, including inductive layer, the inductive layer is coated on the PCB2 plates.
Preferentially, the through hole is circular, square or oval.
Preferentially, including light shield layer, the cover-plate glass lower surface coat the light shield layer.
Preferentially, including semi-transparent photosphere, several hollow out key icons, the hollow out button are opened up on the cover-plate glass
Semi-transparent photosphere described in equal silk-screen on icon.
Preferentially, the light guide plate is the material that can spread light source.
Preferentially, the light guide plate material is PMMA or PC.
The beneficial effect that the utility model is reached：
The utility model is designed using double-layer PCB board, by the hex nut of different size adjust the diffusion of spot light away from
From beneficial to uniform light propagation；Light guide plate 3 is set in the photosensitive layer side of PCB2 plates, not only equalizing light rays is more strengthened, and
And PCB2 plates also turn into " shadow shield " in itself, it is therefore prevented that optical crosstalk occurs；The finally silk-screen in the hollow out key icon of cover-plate glass
Semi-transparent photosphere 42, further homogenizes light beam, while enhances operator's wide-angle visual perception.
