Description

A kind of self-powered remote controller

Technical field

The utility model belongs to technical field of new energy application, is specifically related to a kind of self-powered remote controller, for the controlled in wireless of combination lamp.

Background technology

Traditional fixed lamp switch is connected with light fixture by wire, and because connecting up within the walls, therefore building is difficult to after determining change with the high and position of decoration cost.In recent years, day by day universal along with combination lamp, lamp switch also progressively by wall fixed switch in the past to portable or packaged type remote controller transition.Current lamp remote controller is substantially all battery-powered, cannot use during battery-depletion, and waste battery also can cause 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, the button of patent 200810051579.9 reliably cannot be stirred piezoelectric vibrator because lacking necessary guide and limit and reset smoothly, and reliability is poor; Patent 200810051157.1 and patent 201010165882.9 stir cantilever beam piezoelectric vibrators respectively by rotating moving tooth with the shifting block that can move forward and backward, its structure and motion process are all more complicated and processing and fabricating cost is high, and small fretting wear can cause that moving tooth and shifting block lost efficacy, reliability is low; Stir in excitation power generation process at it it is crucial that above-mentioned and can produce larger noise, be therefore not easy to the application at night of family, and piezoelectric vibrator can damage because institute's tension stress is excessive in double-deformation process.

Summary of the invention

For the series of problems existing for existing lamp remote controller, the utility model proposes a kind of self-powered remote controller based on telescopic piezoelectric vibrator.The embodiment that the utility model adopts is: shell end is equipped with backplate by screw, is provided with circuit board, circuit board is welded with transmitter module inside housing front panel by screw; S type metal film with the circular arc projection piezoelectric film bonding with the protruding place of its circular arc forms piezoelectric vibrator, and piezoelectric vibrator connects through wire L1 between different piezoelectric film, and piezoelectric vibrator is connected with circuit board by wire group L3; The guide that piezoelectric vibrator and its two ends are riveted forms transducer, and on a guide of transducer is enclosed within and has strong market potential, two ends of having strong market potential are placed in the upper end pin-and-hole of housing left and right sidewall respectively; Another guide of transducer is enclosed within short pin, and short pin two ends are placed in the pin-and-hole on bent plate oblique arm, and the convex axle of bent plate oblique arm both sides is placed in the lower end pin-and-hole of housing left and right sidewall respectively; The flat arm of bent plate is equipped with button, and the flat arm of bent plate is provided with wire guide, and wire group L2 passes wire guide and is connected with circuit board by button; The flat arm of bent plate stretches out housing from the window of housing front panel lower end, and button is placed in outside housing.

Generate electricity to greatest extent for making piezoelectric vibrator and avoid piezoelectric film tension stress excessive and damage, piezoelectric vibrator by the least radius of the circular arc external surface of its metal film under the nature of External Force Acting is not $R=\frac{h_m+h_p}{2}\{2\mathrm{\α}+\frac{1}{1-\mathrm{\α}(1-\mathrm{\β})}[{\mathrm{\α}}^2(1-\mathrm{\β})-1-\mathrm{\η}\frac{E_p}{T_p}\left]\right\},$ Wherein α=h _m/ (h _m+ h _p), h _pand h _mbe respectively the thickness of piezoelectric film h2 and metal film h1, $\mathrm{\η}=(1-\mathrm{\α})[1-\mathrm{\α}(1-\mathrm{\β})]+\mathrm{\α\β}/(1+k_{31}^2),$ β=E _m/ E _p, E _pand E _mbe respectively the Young's modulus of piezoelectric film h2 and metal film h1, t _pbe respectively electromechanical coupling factor and the allowable tensile stress of piezoelectric; When the upper side frame of the flat arm upper surface of bent plate and shell window contacts with each other, the length pin centre-to-centre spacing that transducer two ends guide connects should be more than or equal to the centre-to-centre spacing under nature between the guide of transducer two ends, in order to avoid make piezoelectric film bear excessive tension stress and damage.

In the utility model, when external force promotion knob moves downward, knob circuit ON and force bent plate and be installed on short pin on the bent plate convex axle center rotating together on flexing arm, short pin deferent is circular arc, thus make that the centre-to-centre spacing between length pin increases, piezoelectric vibrator is stretched length, converts electric energy in piezoelectric vibrator elongation process by mechanical energy; The electric energy produced directly supplies transmitter module after the electrical energy conversion circuit process on circuit board, and transmitter module sends control signal; After release button, the circuit of knob disconnects, and the elastic force of piezoelectric vibrator self makes bent plate upwards rotate, and piezoelectric vibrator and bent plate are all reset to initial condition; In reseting procedure, piezoelectric vibrator also has electric energy to produce, but because of knob place off-state, signal emission module does not launch effective control signal.

Features and advantages: 1. rotate stretching piezoelectric vibrator by bent plate, and generating is synchronous with switch control rule, thus remote controller general structure and simple to operate, power supply reliability is high, nothing impact and noise; 2. piezoelectric vibrator only bears pulling force effect, and the piezoelectric film not excessive damage of reason tension stress, Mechanical Reliability are high; 3. the stress distribution of telescopic piezoelectric vibrator is even, generating capacity is strong.
