Utilize kinetic energy can have on the principle electromagnetism, static, three kinds of dynamo-electric conversion regimes of piezoelectricity available, the comprehensive external existing technology of utilizing kinetic energy, total trend is to adopt various novel piezoelectric materials as energy transducer, by to the conditioning of moment, unordered electric energy, the orderly output that storage realizes electric energy.Allowing footwear, clothes, toy possess the novelty that illumination effect can not only increase product, and possess the effect of caution, is a simple method that effectively increases added value of product.Along with the miniaturization of electronic equipment, integrated, low power consumption, the product of a large amount of being equipped with " wearable electron emitting structure " has appearred on the market, as luminous footwear, luminous clothes, luminous glasses etc., formed a huge industrial colony.Prior art need be equipped with compact battery as drive energy for each electron emitting structure, has not only limited the useful life of product, and can cause huge pollution to environment after abandoning.
[summary of the invention]
The purpose of this invention is to provide a kind of parasitic energy when utilizing daily action, need not specific manual mode of operation's novel kinetic energy illuminator.
The key issue that product of the present invention solves comprises the following aspects:
1, the design of piezo-electric generating transducer and exploitation.Choose suitable piezoelectric physical characteristic, electrical characteristic etc., and, make the piezo-electric generating transducer that is applicable to the different operating mode based on kinesiology principle design and arrangement switching device.
2, switching mode conversion, memory technology research.The purpose of this part Study is to realize the orderly release of unordered electric energy, and design is with conversion, the memory of electric capacity as energy-storage travelling wave tube.Determine piezo-electric generating energy transducer parameter and follow-up charge-discharge circuit parameter by system modelling and emulation technology, make system works, improve transducing, storage efficiency to greatest extent in resonance state.Obtain continuing or the output of burning voltage intermittently.
For overcoming the above problems, the technical scheme that the present invention takes is:
A kind of kinetic energy illuminator is provided, and it comprises piezo-electric generating transducer and the light-emitting component that is connected.This light-emitting component is a light-emitting diode.This piezo-electric generating transducer is with PZT (Lead ZirconateTitanate, lead zirconate titanate) piezoelectric ceramic is a transductive material, this transductive material is worked in 31 modes, two piezoelectrics reverse polarization series connection are bonded in FRP (Fiber Reinforce plastics, fiberglass-reinforced plastic) on the circuit board, constitute twin crystal piezo-electric generating transducer, can take one of mode of operation of free impact, forced vibration, free vibration.

Because the PZT pottery has very big d
33, so its most effective working method should to work as be to compress by 33 modes to obtain, but we obtain by following analysis, this working method can only obtain effective energy seldom because
In the formula, F is an external force, and H is the load height, and A is a lifting surface area, and Y is a modulus of elasticity.To PZT pottery Y usually up to 4.9 * 10
10N/m
2, therefore need huge strength just can make it to take place compressive deformation.And 31 modes that work in are much easier, because the crisp hard characteristics of material itself, undressed PZT can only bear very little deformation on this direction.Common maximum surface strain is no more than 5 * 10
4Surface strain is as shown in the formula definition:
X represents deformation quantity in the formula, and t is overarm arm thickness, L
cLength for beam.Like this, one thick 0.002 PZT thin slice is arranged on that its maximum flexibility displacement can be on the overarm arm of long 20cm:
As seen this structure has very big application potential.Can set 3 kinds of different mode of operations at different application after adopting the spring beam structure: free impact, forced vibration, free vibration.These several modes can be developed and be applicable to the piezo-electric generating energy transducer by vibrating power-generation such as toy.
The design of 2, conversion, memory circuit: utilize the electric energy of piezo-electric generating transducer output that dual mode is arranged, a kind of is directly to connect luminescent device such as LED, and another kind of mode is to realize discharging in order by conversion, storage.The sort of power way of output no matter, all can represent with following power output model:
I
0＝V/(Z
0+Z
L)
Z
L=Z
0The time,
Find out from above analysis, impedance matching plays crucial effects to the output of power, because PZT and PVDF (PolyvinylideneFluioride, polyvinylidene fluoride) material have very big internal resistance (hundreds of k), so load also needs bigger internal resistance to match.In order to realize the orderly release of energy, the present invention has adopted the conversion memory.
The conversion of conversion memory, memory circuit comprise rectifier, energy-storage travelling wave tube, SCR ghyristor circuit, voltage stabilizing chip, the voltage that comes out from the piezo-electric generating transducer by rectification after by the energy-storage travelling wave tube storage, discharge, by the SCR ghyristor circuit high impedance of piezo-electric generating transducer is mated accordingly again and realize switch control, connecting the output of voltage stabilizing chip again continues or burning voltage intermittently, realize switch change-over, last driven for emitting lights device is luminous.
Compared with prior art, the present invention has following beneficial effect:
Adopt modification piezoelectric ceramic (PZT) as the piezoelectric energy-conversion material, can be easily at different application design piezo-electric generating energy transducer.According to principle of dynamics design and placement switching device, energy transducer is provided with flexibly the different working modes of free impact, forced vibration, free vibration at different application.
And can determine piezo-electric generating energy transducer parameter and follow-up charge-discharge circuit parameter by system modelling and emulation technology, make system works, improve conversion efficiency to greatest extent in resonance state.
In order to realize the orderly release of unordered electric energy, design is with the DC-DC switch converter of electric capacity as energy-storage travelling wave tube.Can obtain burning voltage output lasting or intermittently by this converter, the drive controlling chip is realized the multiple flicker effect of LED.
Kinetic energy illuminator of the present invention need not specific manual mode of operation and can utilize the parasitic energy luminous, the reliability height, and in light weight, volume is little, low-cost, have output of high relatively electric weight and electric energy transmitting easily, can be used for traditional industries such as shoemaking, clothes, toy.Can solve the life problems that luminous product is brought because of the battery capacity restriction by Products Development application of the present invention, and meet the environmental protection theory, be the renewal product of active luminous flashing light product.
