Description
Technical field
The invention belongs to new forms of energy and technical field of power generation, be specifically related to a kind of Manual press spherical limiting circular piezoelectric vibrator power generation device, be used for the power supply of lamp remote controller or remote control switch.
Background technology
The switch control of lighting is that any family and office space are all indispensable.Traditional fixed lamp switch connects with light fixture by wire, because need connect up within the walls, therefore be difficult to change after building and location positioning high with decoration cost.In recent years, along with the popularization and application of combination lamp, lamp switch also progressively by wall fixed switch in the past to portable or packaged type remote controller transition.Present lamp remote controller is substantially all battery-powered, can't use when battery power exhausts, and waste battery also can cause serious environmental pollution and the wasting of resources simultaneously.For this reason, people have successively proposed based on electromagnetic power generation apparatus, such as Chinese patent 201020190448.1,200920003419.7 and 01255765.X etc., or the remote switch for lamps of piezoelectric generating device power supply.The energy conversion efficiency of electromagnetic power generation apparatus is relatively high, but can produce electromagnetic interference in power generation process, and then affects reliability and the accuracy of remote controller.By comparison, piezoelectric generating device utilizes the flexural deformation of sheet type piezoelectric vibrator to convert mechanical energy to electric energy, have simple in structure, cost is low and power generation process in piezoelectric vibrator do not generate heat, do not produce the characteristics such as electromagnetic interference.
Utilizing aspect piezoelectric generating device structure electric non-battery remote controller or the remote control switch, domestic existing more patent application, Chinese patent 200520111441.5 and 00817016.9 has been introduced respectively two kinds of piezoelectric generating devices based on strike/bump mode, and Chinese invention patent 200520008424.9 has been introduced a kind of button that utilizes and has been Blast Furnace Top Gas Recovery Turbine Unit (TRT) and the remote controller thereof of the piezoelectric element application of force.Above-mentioned patent all is to utilize 1 piezoelectric vibrator, its generating operation energy output can't satisfy the power demand of remote controller emission system at all, and can only adopt repeatedly the method for electrification energy storage to power, do not meet remote controller, the especially operating habit of fixed lamp switch.Therefore, the inventor had once proposed the remote controller of two kinds of dial type piezoelectric self-powersupplies: Chinese invention patent 200810051579.9,200810051157.1, but Development Practice subsequently shows, the generating operation scheme of above-mentioned self-powered remote controller is difficult to realize: the button of patent 200810051579.9 can't be stirred reliably piezoelectric vibrator because of the guide and limit that lacks necessity and reset smoothly, and reliability is relatively poor; Patent 200810051157.1 and 200820072434.2 is stirred cantilever beam piezoelectric vibrators by rotating moving tooth, and its structure and motion process are complicated, and small fretting wear can cause moving tooth to lose efficacy, and manufacturing cost is higher.Deficiency for above-mentioned dial type piezoelectric generating device, the inventor proposes a kind of new dial type Blast Furnace Top Gas Recovery Turbine Unit (TRT) again: Chinese patent 201010165882.9, practice shows, this structure Blast Furnace Top Gas Recovery Turbine Unit (TRT) is easy to processing and fabricating, also can produces enough electric energy, weak point is the control that is difficult to realize a plurality of light fixtures: can't establish a plurality of buttons, a switch only can be controlled a lamp, and the problem that exists equally campaign-styled trigger mechanism parts to lose efficacy because of fretting wear.In addition, in the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of above-mentioned all cantilever beam piezoelectric vibrators, only produce in the longitudinal direction after the piezoelectric vibrator free end is stressed on flexural deformation, the Width without distortion, stress does not change, therefore the energy output when piezoelectric vibrator area and thickness are identical is far below the energy output of circular piezoelectric vibrator, circular piezoelectric vibrator radially and tangentially STRESS VARIATION is arranged all, therefore generating capacity is strong; And the dial type Blast Furnace Top Gas Recovery Turbine Unit (TRT) easily produces fatigue damage when also producing vibrating noise, piezoelectric vibrator dynamic duty in operating process.
Summary of the invention
The invention provides a kind of spherical limiting circular piezoelectric vibrator power generation device, be used for the remote controller power supply, with solve existing remote controller with piezoelectric generating device because of generating capacity a little less than, to operate inconvenience or unreasonable structure etc. former thereby the problem such as be difficult to apply.
The technical solution used in the present invention is: the upper shell end is provided with the bearing that connects bearing pin, is used for mounting circuit boards, circuit board is fixed on the bearing by screw, inside is equipped with circular piezoelectric vibrator and is used for making it to produce the diastrophic upper spherical limiting piece of iso-curvature, and upper surface is equipped with shift knob; The lower house end is provided with engaging lug, inside is equipped with circular piezoelectric vibrator and is used for making it to produce the diastrophic lower peripheral surface guide vane end stop of iso-curvature, be rotationally connected ball on the lower peripheral surface guide vane end stop, the hole that upper shell is connected with lower house on connection bearing pin and the engaging lug is hinged, upper spherical limiting piece and ball crimping.
The generating parts are the circular piezoelectric vibrator of two parallel connections, piezoelectric chip on the described piezoelectric vibrator is connected with metal substrate by two connections of wire group, link to each other with power circuit on the printed circuit board (PCB) through wire group one, this power circuit links to each other by the circuit of wire group three with shift knob and remote controller emission system more again.
In the present invention, upper shell, lower house, a pair of circular piezoelectric vibrator, two spherical limiting pieces, one jointly consist of Blast Furnace Top Gas Recovery Turbine Unit (TRT) at the ball between the spherical limiting piece up and down and the one group of button and the circuit board that are installed on the upper shell.When pressing described button, upper shell connected and drive by button and inner piezoelectric vibrator and spherical limiting piece rotates along the end bearing pin, and the effect of ball is upper shell to be rotated the pressure that produces pass on the spherical limiting piece and piezoelectric vibrator that is arranged in lower house; With the lasting rotation of upper shell, two piezoelectric vibrators occur bending and deformation gradually, and finally are attached to spherical limiting piece surface, and this is power generation process; Discharge button, after external force was removed, button disconnected, and piezoelectric vibrator recovers distortion and drive upper shell to return back to initial position in the effect of himself elastic force.
Characteristics of the present invention and advantage are:
Utilize spherical limiting to make circular piezoelectric vibrator produce the flexural deformation of iso-curvature radius, the electric weight of the suffered stress of its surperficial each point and generation is identical.When the suffered maximum stress of piezoelectric vibrator was identical, total energy output can improve more than 8 times, compared with piezoelectric vibrator center local compression, and this moment, piezoelectric vibrator pressurized place stress/energy output was maximum and edge is 0;
The piezoelectric vibrator stress distribution is even during spherical limiting, can avoid damaging because local stress is excessive;
Adopt the cogeneration of two piezoelectric vibrators, by the direct transmitting torque of fashion of extrusion, need not complicated motion, noiselessness in the operating process between each piezoelectric vibrator;
