Accompanying drawing explanation
Fig. 1 is described in the utility model near the structure rough schematic view putting lit touch controlled key panel.
Fig. 2 is described in the utility model near the schematic block circuit diagram putting lit touch controlled key panel.
Below by way of the drawings and specific embodiments, this utility model is further described:
Detailed description of the invention
As illustrated in fig. 1 and 2, one described in the utility model, near some lit touch controlled key panel, utilizes special structural design, it is achieved staff near time automatically light in advance the backlight of key panel, it is prevented that ambient light is dim and maloperation.Its concrete structure is as follows:
Described in the utility model near some lit touch controlled key panel include transparent touch controlled key panel 1, MCU2, LED drive module 3, LED backlight group 4, touch chip module 5, clickwheel group 6, close to inductance loop 7, timing module 8 and power supply 9.
Described MCU2 is used for collecting and processing related data；
Described LED drive module 3 electrically connects with MCU2, supports for providing to drive for LED backlight group 4；
Described LED backlight group 4 is located at the back side of touch controlled key panel 1 and electrically connects with LED drive module 3；
Described touch chip module 5 electrically connects with MCU2, for scouting clickwheel group 6 and being inducted out trickle electric current by human magnetic field close to inductance loop 7；
Described clickwheel group 6 is located at the back side of touch controlled key panel 1 and electrically connects with touch chip module 5, it includes several clickwheel, the present embodiment lists six clickwheel, the corresponding corresponding function button of each clickwheel, respectively clickwheel A, clickwheel B, clickwheel C, clickwheel D, clickwheel E and clickwheel F.Further, described clickwheel group 6 senses clickwheel group for appearance formula.When the finger of people touches clickwheel, sensed by the appearance formula of clickwheel, human magnetic field is inducted out trickle electric current, detected by touch chip module 5, according in advance coding to different clickwheel addresses, MCU2 just can judge that function button which clickwheel is corresponding is by by arriving, thus the implication that foundation button gives, can go to perform corresponding instruction, complete required manipulation.
Described being located at the back side of touch controlled key panel 1 close to inductance loop 7 and be enclosed in the periphery of clickwheel group 6, in open annular, namely described is not a closed-loop close to inductance loop 7, and it has an opening；Described electrically connect close to inductance loop 7 with touch chip module 5.Described close to inductance loop 7 be rectangle close to inductance loop, or be oval close to inductance loop, or be circle close to inductance loop.The described border width close to inductance loop 7 is 1.5mm.Further, described close to inductance loop 7 be Copper Foil close to inductance loop.Structural design close to inductance loop 7 makes induction range effectively amplify, it is possible to sense from close to the human magnetic field within inductance loop 15cm.
Described timing module 8 electrically connects with MCU2, for calculating and the lighting time of timing LED backlight group 4, when close to inductance loop 7 sense staff close to time, LED backlight group 4 light can be lighted automatically, and it is wash rice lit, slowly demonstrate keypress function symbol instruction clearly and profile, be operated to facilitate people to go.And the timing module several seconds after end of operation, it enters again OFF state gradually.
When user wants to carry out a manipulation, the finger of people is progressively close to touch controlled key panel 1, when distance is from during close to inductance loop 7 about 15cm, the magnetic field effect of human body can be sensed close to inductance loop 7, the extremely trickle electric current generated, touch chip module 5 captures the electric current that these are trickle, form relevant information and be sent to MCU2, MCU3 by internal calculating, it is judged that out the operation of user is intended to, start LED drive module 3, light the LED backlight group 4 of touch screen.User illuminates touch controlled key panel 1 by LED backlight group 4, next can be carried out the button operation of routine, when user goes by when contacting certain clickwheel (corresponding corresponding function button) with hands, by holding formula sensing, the extremely trickle electric current generated, touch chip module 5 similarly communicates with MCU2, MCU2 judge by the key value of the clickwheel corresponding function energy button arrived, and send instruction to its corresponding functional circuit, go corresponding manipulation, such as volume plus-minus, the change etc. of audio.IIC communication mode is adopted to carry out communication between MCU2 and other each module.Touch controlled key panel described in the utility model, its operation had both been imbued with hommization, can reach again the purpose saved energy and reduce the cost, and made the manipulation of product be full of enjoyment.
This utility model utilize be enclosed in clickwheel group peripheral realize triggering close to sensing every empty close to inductance loop, staff near time automatically light the backlight of key panel in advance, it is prevented that ambient light is dim and maloperation.
