Embodiment
Specify below in conjunction with accompanying drawing embodiment.
With reference to Fig. 1-5, present embodiment sliding touch display unit mainly comprises: the circuit board 1, bar shaped skeleton 2 and the some flexible sensor blocks 3 that are loaded with the identification control module.
One exhausting hole 22 is set at interval on the bar shaped skeleton 2, and the upper edge is extended corresponding with this through hole 22 one and is arranged light shield 21, and bar shaped skeleton 2 is arranged on the circuit board 1.Some flexible sensor blocks 3 are installed in respectively in the through hole 22 of correspondence of said bar shaped skeleton 2; And the splicing ear 12 of a corresponding charge detection unit electrically contacts and constitutes a sensor key on each flexible sensor block 3 and the circuit board 1; Corresponding with the corresponding light shield of this sensor key 21 zone LED 11 that is welded that hints obliquely on circuit board 1; Said identification control module is used to discern said flexible sensor block is slided and is touched or the some touch sensible, and drives the luminous formation striation of corresponding LED.
The splicing ear of above-mentioned charge detection unit is positioned at a through hole 22 of bar shaped skeleton 2, and this splicing ear is thin and be welded on 3-5 the tin welding spot of this copper on thin and form by a slice copper corresponding on the circuit board.The splicing ear that can guarantee flexible sensor block and charge detection unit so reliably electrically contacts, and keeps the balance of flexible sensor block in bar shaped skeleton 2 through holes 22.
Like Fig. 4, deviate from from the through hole 22 of bar shaped skeleton 2 for avoiding flexible sensor block 3, on these through hole 22 inwalls, be symmetrically arranged with button bit 23,24 and be the little axle in location.
Fig. 5 is the enlarged drawing of the flexible sensor block 3 among Fig. 1.Flexible sensor block 3 is cotton piece of conductive foam or conductive rubber block etc.This flexibility sensor block 3 comprises foam-plastic blocks 32 and the conductive fabric 31 that is coated on these foam-plastic blocks 32 surfaces.
In other embodiment, flexible sensor block can be made up of block rubber and the conductive film that is coated on this block rubber surface.
Flexible sensor block is a hexahedral shape, and cross section is rectangular.According to design demand, flexible sensor block can be designed as cylindrical shape, cylindroid shape etc.
Circuit parts such as identification control module are with reference to theory diagram 6,7.The identification control module comprises microprocessor MCU, signal generator, analog to digital converter ADC, variable connector, communication interface and 7 charge detection unit etc.Signal generator is connected in the control end of MCU; MCU one input connects ADC; The ADC input connects variable connector, and each input of variable connector connects a charge detection circuit respectively, and the input of all charge detection unit all receives 100 ~ 1000kHz pulse signal that signal generator is presented; Corresponding with each light shield of bar shaped skeleton 2 21 zone two LED 11 that are welded that hint obliquely on circuit board 1, these LED are respectively by the port driver of MCU.
The identification control module preferably adopts built-in MCU, ADC and the SoC chip (like 13 among Fig. 3) of the signal generator etc. of 100-1000kHz pulse signal can be provided.The 100-1000kHz pulse signal that signal generator produces can be that square wave also can be sinusoidal wave, also can adopt the signal generator among the MCU directly to produce.
Fig. 7 charge detection unit comprises the capacitor C 1 and capacitor C 2 that is connected in series; Capacitor C 2 free ends connect the lead-out terminal of charge detection circuit through rectifier diode D2; Be connected load resistance R2 between this lead-out terminal and the ground; The positive pole of rectifier diode D2 oppositely meets diode D1 to ground; The common port of capacitor C 1 and capacitor C 2 is through resistance R 1 ground connection; The common port of these two capacitor C 1, C2 is connected to a splicing ear 12 (Fig. 3 splicing ear 12 by a slice copper corresponding on the circuit board thin and be welded on 3-5 the tin welding spot of this copper on thin and form) of above-mentioned correspondence simultaneously, and this splicing ear 12 is positioned at bar shaped skeleton 2 corresponding through holes 22 times, and and these through hole 22 interior flexible sensor blocks 3 reliably electrically contact.
The high-frequency signal that signal generator produces through rectifier diode D2 rectification, generates dc level signal (being charge detection unit output voltage) through capacitor C 1, C2 at load resistance R2 two ends, convert digital quantity input MCU through variable connector to by ADC.Under the normal condition, the flow through quantity of electric charge of capacitor C 1, C2 of the high-frequency signal that signal generator produces is certain, also is certain by the level signal after the rectifier diode D2 rectification; When the said gentle property sensor block 3 that electrically contacts with splicing ear 12 of the finger touch of human body; Finger and the flexible sensor block 3 surperficial inductance capacitances that form a bleed off electric charge; When the high-frequency signal process capacitor C 1 that signal generator sends, C2; Part electric charge will pass through said flexible sensor block 3 and the inductance capacitance that human finger forms, and flow to the earth through the human body transfer, thereby the level signal after the D2 rectification is descended.MCU will detect the level signal variable quantity before and after the human finger touch sensible, analyzing and processing; Obtain having or not the judgement of human finger near said sensing chip; Be transferred to main frame through communication interface, and drive the luminous formation light belt of corresponding LED according to setting program.
Because this practical sliding touch display unit is a strip sensor key row member; Some sensor keys are arranged; MCU can detect the position of finger on sensor key row at a high speed; And will light LED lamp that should sensor key, when sliding on sensor key row, finger touches or point when touching, and the LED that the MCU may command is set lights the formation light belt successively.
Can realize that through this sliding touch display unit the touch-control light belt shows.When sliding, finger touches or the flexible sensor block 3 of some touch; The said flexible sensor block 3 that is touched or put touch sensible by sliding is gone out by corresponding electric charge detection; And then through identification control module identification processing; Drive the luminous formation light belt of corresponding LED with setting program, and give main frame through communication interface transmission data.
When finger forward slides when touching to the other end from an end of said device, the corresponding LED of corresponding sensor key that is responded to just successively one one light, and then finger slides to prolong and forms a light belt; When the reverse slip of finger touches, the LED that was lighted originally just successively one one extinguish, light belt shortens with the slip of finger.
Forward put when touching from the top terminad of said device when finger, when point touched certain sensor key position, all corresponding LED of sensor key to this sensor key were lighted one by one from top, formed a light belt of top sensor key-this sensor key; Corresponding LED extinguishes successively after pointing when top direction point touches, put the sensor key position that touches, and light belt is with the mobile shortening of pointing, till initiating terminal.
This device can be disposed at small household electrical appliance and use as input block, like electromagnetic oven, electric heater or the like.As the utility model sliding touch bar being installed, can form products such as sliding touch electromagnetic oven with light belt Presentation Function at the window place of electromagnetic oven operation face-piece.
