Description

A kind of electric non-battery remote controller

Technical field

The invention belongs to new forms of energy application, be specifically related to a kind of electric non-battery remote controller, wireless for combination lamp Control.

Background technology

Traditional fixed lamp switch is connected with light fixture by wire, because connecting up within the walls, therefore building and decoration cost High and position is difficult to change after determining.In recent years, along with becoming increasingly popular of combination lamp, lamp switch is the most progressively by conventional wall Wall fixed switch is to portable or packaged type remote controller transition.Current lamp remote controller is the most battery-powered, electricity Cannot use when pond electric energy exhausts, waste battery will also result in serious environmental pollution and the wasting of resources simultaneously.Therefore, inventor Proposed the remote controller of multiple dial type piezoelectric self-powersupply once, as Chinese patent 200810051579.9, 200810051157.1 and 201010165882.9 etc., but Development Practice subsequently shows, pressing of patent 200810051579.9 Key cannot reliably be stirred piezoelectric vibrator because lacking the guide and limit of necessity and reset smoothly, and reliability is poor；Patent 200810051157.1 and patent 201010165882.9 stir cantilever by rotating moving tooth and setting ahead of can moving forward and backward respectively Beam piezoelectric vibrator, its structure and motor process is the most complicated and processing and fabricating cost is high, small fretting wear i.e. may result in and dials Tooth and shifting block lost efficacy, reliability is low；Loud noise can be produced, therefore in it stirs excitation power generation process it is crucial that above-mentioned It is not easy to the application at night of family, and piezoelectric vibrator can damage because institute's tension stress is excessive during double-deformation.

Summary of the invention

For the series of problems existing for existing lamp remote controller, the present invention proposes a kind of based on telescopic piezoelectric vibrator Self-powered remote controller.The present invention adopted implementation scheme is that shell end passes through screw equipped with backplate, inside housing front panel By screw equipped with circuit board, circuit board is welded with transmitter module；The S type metal film protruding with circular arc and its circular arc projection place Bonding piezoelectric film constitutes piezoelectric vibrator, and the different piezoelectricity on piezoelectric vibrator are intermembranous through wire L1 connection, and piezoelectric vibrator is by leading Line group L3 is connected with circuit board；The guide that piezoelectric vibrator and its two ends are riveted constitutes transducer, and the guide at transducer two ends divides Not being enclosed within rationed marketing and untie-sell, rationed marketing two ends are respectively placed in the pin-and-hole of housing left and right sidewall upper, and untie-sell two ends are respectively placed in In longitudinal guide groove of housing left and right side wall lower ends；The guide groove on two side, square chamber on bent plate oblique arm is enclosed within untie-sell, and bent plate stands The protruding shaft of arm both sides is respectively placed in the pin-and-hole of housing left and right side wall lower ends, equipped with button on the flat arm of bent plate, the flat arm of bent plate sets Having wire guide, wire group L2 connecting button and circuit board passes from wire guide；The bent plate flat arm window from housing front panel lower end Mouth stretches out, and button is placed in outside housing.

For making piezoelectric vibrator generate electricity to greatest extent and avoiding the excessive damage of piezoelectric film tension stress, piezoelectricity Oscillator by the least radius of its metal film circular arc external surface under the naturalness of External Force Acting is notWherein α=h_m/(h_m+h_p), h_pAnd h_mPoint Not Wei piezoelectric film and the thickness of metal film,β=E_m/E_p, E_pWith E_mIt is respectively piezoelectric film and the Young's modulus of metal film, k₃₁、T_pIt is respectively the transverse electromechanical coupling factor of piezoelectric and allowable Tension；When the upper side frame of bent plate flat arm upper surface Yu shell window contacts with each other, the rationed marketing that transducer two ends guide is overlapped With the centre-to-centre spacing between untie-sell should be greater than or equal to centre-to-centre spacing between the guide of two ends on transducer under naturalness, to avoid making piezoelectricity Film damages because bearing excessive tension.

In the present invention, when external force pushes down on knob, the circuit ON of knob and button force bent plate around its armstand two The center rotating of side protruding shaft；Meanwhile, the top edge of bent plate upper rail promotes the untie-sell that is placed in described guide groove along about housing The vertical guide slot of side wall lower ends moves down, so that the centre-to-centre spacing between rationed marketing and untie-sell increases, piezoelectric vibrator is stretched length, pressure Electric tachometer indicator elongation process i.e. converts mechanical energy into electric energy；Produced electric energy electrical energy conversion circuit on circuit board processes After directly feed transmitter module, transmitter module sends control signal；After release button, the circuit of knob disconnects, and piezoelectric vibrator is certainly The elastic force of body makes bent plate be rotated up, and piezoelectric vibrator and bent plate are all reset to original state；Piezoelectric vibrator in reseting procedure Also there is electric energy to produce, but because the circuit of knob is off, the signal emission module on circuit board does not launch effectively control Signal.

Characteristic and advantage: 1. rotate stretching piezoelectric vibrator by bent plate, and generating is Tong Bu with on-off control, therefore remote controller is total Body structure and simple to operate, power supply reliability is high, without impact and noise；2. piezoelectric vibrator is subjected only to pulling force effect, and piezoelectric film is not The excessive damage of reason tension, Mechanical Reliability height；The stress distribution of the most telescopic piezoelectric vibrator is uniform, generating capacity is strong.
