Description
Technical field
The utility model belongs to new forms of energy and technical field of power generation, is specifically related to a kind of button Piezoelectric switches TRT, is used for the remote switch for lamps power supply.
Background technology
Utilize the patent of piezoelectric generating device structure electric non-battery remote controller and lamp switch domestic morning application to be arranged, but because of aspects such as generating device structure and generating capacity exist certain deficiency and drawback, still manque so far applying.For example; Chinese invention patent 200520111441.5 and 00817016.9 has been introduced two kinds respectively based on hitting, clashing into the piezoelectric generating device of mode, and Chinese invention patent 200520008424.9 has been introduced a kind of TRT and remote controller thereof that utilizes button for the piezoelectric element application of force.In the above-mentioned patent; What utilize all is single piezoelectric vibrator; The energy that its generating operation produces can't satisfy the power demand of remote controller emission system at all, and can only adopt the method power supply of repeatedly generating storage accumulation, does not meet the operating habit of remote controller, especially fixed lamp switch.The remote controller that the dial type piezoelectric self-powersupply is similarly also arranged; Like Chinese invention patent 200810051579.9,200810051157.1 etc.; But the structure of above-mentioned self-powered remote controller and motion process are complicated, and small fretting wear can cause moving tooth to lose efficacy, and manufacturing cost is higher.
Summary of the invention
For solve existing piezo-electric generating switch because of generating capacity a little less than, problem such as operation inconvenience; The utility model provides a kind of button Piezoelectric switches TRT; Drive pressing plate and move down and make a plurality of piezoelectric vibrators produce the distortion generating through pinning shift knob on the pressing plate; In the piezoelectric vibrator generating, accomplish switch control, meet the operating habit of lamp switch.
The technical scheme that the utility model is taked is: the pressing plate upper surface is equipped with shift knob, and circuit board is inner in pressing plate through screw, and the pressing plate lower end is provided with application of force briquetting, and pressing plate is provided with four guide posts for four jiaos, and the guide post end is provided with the chucking structure; 1-10 curved PZT (piezoelectric transducer) is positioned at lower house, and four gathering sills are arranged on the lower house, and four guide posts on the pressing plate are connected on the lower house through the chucking structure and the inner spacing preiection of gathering sill of spring, guide post end; Application of force briquetting and conductive rubber briquetting are bonding, the piezoelectric vibrator in conductive rubber briquetting and the curved PZT (piezoelectric transducer) is bonding, and the piezoelectric vibrator in the adjacent PZT (piezoelectric transducer) also is bonding through the conductive rubber briquetting.
A kind of execution mode that the utility model is taked is: said PZT (piezoelectric transducer) is formed with the rivet symmetry riveting by a pair of piezoelectric vibrator, and piezoelectric vibrator is adhered to rectangular metal sheet by piezoelectric chip and constitutes, and metal bonding film is in the conductive rubber briquetting; The sheet metal of different PZT (piezoelectric transducer)s connects through lead group one, and the piezoelectric chip of same curved PZT (piezoelectric transducer) is connected by lead group two; Sheet metal and piezoelectric chip are connected with power circuit on the circuit board through lead group three again, and this power circuit links to each other with shift knob through lead group four again.
Through pinning the shift knob on the pressing plate, shift knob is connected, and drives pressing plate and inner circuit board moves down along gathering sill, and the application of force briquetting on the pressing plate forces piezoelectric vibrator to occur bending and deformation through the conductive rubber briquetting more simultaneously; Along with pressing plate continue move down, the deflection of piezoelectric vibrator increases gradually, touches lower house until pressing plate, this is a power generation process; Release switch button, after external force was removed, shift knob broke off, and pressing plate is reset to initial position under the effect of spring and piezoelectric vibrator.
The beneficial effect of the utility model is: 1. used PZT (piezoelectric transducer) by the riveted joint of two piezoelectric vibrators form, TRT is in series by a plurality of PZT (piezoelectric transducer)s, need not any auxiliary body each piezoelectric vibrator is generated electricity simultaneously; 2. adopt conductive rubber to make the briquetting that is used for transferring power between PZT (piezoelectric transducer), piezoelectric vibrator is not fragile, the operation noiselessness; 3. drive pressing plate and move down and make the piezoelectric vibrator generating through pinning shift knob on the pressing plate, and accomplish switch control simultaneously, meet the operating habit of lamp switch.
