The course of work of this body-building device is as follows
The mechanical driving part explanation
When a people when treadmill moves, runs and to be with 9 to drive front wheels 19 and rotate, thereby driven gear I15 rotates, gear I15 links to each other with gearbox, freewheel clutch A25 breaks away from, and freewheel clutch B27 combination, thus driving generator 26 rotates the generation electric energy; Simultaneously, being attached to the power conversion that the piezoelectric ceramics on the running board will ride on running board is electric energy;
When a people when Spinning moves, big belt wheel 12 drives small pulleys 14 and rotates, small pulley 14 is connected with gearbox by axle I22, at this moment, freewheel clutch B27 breaks away from, freewheel clutch A25 connects, and drives generator 26 and rotates the generation electric energy;
When a people is carrying out arm strength when taking exercise, because reciprocating motion causes the distortion of spring 11, the elastic deformation of spring 11 makes the piezoelectric 45 that is attached to the slide block end face that piezo-electric effects take place, and the electric energy of generation is collected after the circuit rectification.
When two people simultaneously respectively when treadmill and Spinning move, because there is speed difference in both motions, another breaks away from so the meeting that its medium velocity of freewheel clutch A25, B27 is bigger connects, thereby guarantees to rotate the generation electric energy by the higher drive generator 26 of rotating speed.
When the treadmill device folded, the sleeve 16 of treadmill below was rotated around the axle on the seat board support 1, and along with the rising of treadmill, the sliding bar 17 that links to each other with treadmill slides in sleeve 16.When treadmill rotated to appointed positions, the fastening bolt that tightens between sliding bar 17 and the sleeve 16 can be fixed treadmill.
When bicycle partly folds, extract the bolt between seat board support 1 and the seat board support bar 2, seat board support bar 2 is rotated counterclockwise around connecting rod I3, connecting rod I3 turns clockwise around seat board support 1, and seat board support 1 is rotated counterclockwise centered by bracket I 5 and seat board support 1 junction can finish the folding of this part.
The electric energy conversion portion
The electric energy conversion portion can be divided into again and utilizes piezo-electric effect that mechanical energy is converted to the part of electrical power storage and drives the part that generator work is converted to mechanical energy electrical power storage.
When piezoelectric ceramics being applied a pressure F parallel with polarised direction, shown in Fig. 9 a, crystal will produce compressive deformation (dotted line among the figure), and the distance between the intracrystalline positive and negative bound charge diminishes, and polarization intensity also diminishes.Therefore, be adsorbed on the free charge on the electrode originally, some is released, and electric discharge phenomena occur.After pressure was cancelled, crystal restored to the original state (this is an expansion process), and the distance between the intracrystalline positive and negative electric charge becomes big, and polarization intensity also becomes greatly, so adsorbed a part of free charge again on the electrode and charging phenomenon occurs.Thisly changing electrical effect into by mechanical effect, perhaps changed into the phenomenon of electric energy by mechanical energy, is exactly direct piezoelectric effect.Opposite, if add an electric field identical with polarised direction at piezo-electric crystal, shown in Fig. 9 b, because the direction of electric field is identical with the direction of polarization intensity, so effect of electric field increases polarization intensity.At this moment, distance also increases between the intracrystalline positive and negative bound charge, and in other words, crystal produces elongation deformation (dotted line among the figure) along polarised direction.
In like manner, if the direction of extra electric field is opposite with polarised direction, then crystal produces along polarised direction and shortens deformation.This owing to electrical effect changes mechanical effect into or changes the phenomenon of mechanical energy into by electric energy, be exactly inverse piezoelectric effect.This shows, so piezoelectric ceramics has piezo-electric effect, be because there is spontaneous polarization in ceramic inside.These spontaneous polarizations are through the processing of hyperpolarization operation and after being forced to orientations, namely have remanent polarization in the pottery.If extraneous effect (as pressure or effect of electric field) can make this polarization intensity change, piezo-electric effect just appears in pottery.In addition, it can also be seen that the polarization charge in the pottery is bound charge, rather than free charge, these bound charges can not move freely.So the discharge that produces or charging phenomenon are the variations by ceramic internal polarization intensity, cause the release of free charge on the electrode surface or additional result in pottery.
This device utilizes the piezoelectric generating device of the direct piezoelectric effect design of piezoelectric ceramics just, and the electricity collection of its generation is stored the consumption that is used for compact electric apparatus.
In containing the circuit of piezoelectric, the factor that influences energy transmission efficiency has two: the loss of energy in the loop in (1) charge transfer process, the dump energy of piezoelectric ceramics self after (2) energy end of transmission.Under the bigger situation of memory capacitance, energy consumes in charge transfer process in a large number; Under the situation of memory capacitance less than piezoelectric ceramics electric capacity, the low main cause of energy transmission efficiency is the latter.The relative memory capacitance of equivalent capacity of general piezoelectric ceramics is very little.In order to guarantee to store enough energy, the capacity of memory capacitance can not be too little.For improving energy transmission efficiency, has only the equivalent capacity that improves piezoelectric ceramics.Adopt method and the rational electric connecting mode of multi-disc piezoelectric ceramic piece, improve the equivalent capacity of piezoelectric ceramics.
The connected mode of piezoelectric ceramic piece has two kinds, i.e. in parallel and series connection.Know that from electric capacity connection in series-parallel character if two piezoelectric ceramic piece parallel connections concentrate on negative electrical charge on the middle negative electrode, positive charge is equivalent to two electric capacity parallel connections on upper and lower two positive electrodes, output total electrical charge and capacitance double.If two piezoelectric ceramic piece series connection, positive and negative charge offsets on two piezoelectric ceramic piece targets, and the output total electrical charge is constant, and by electricity knowledge, capacitances in series is equivalent to the resistance parallel connection, so two piezoelectric ceramic piece series electrical capacity reduce by half.Therefore, for raising the efficiency, we select parallel way, as shown in figure 10.Piezoelectric 45 is divided into Multi-layer Parallel, and interlayer is provided with supporting 46.
This device produces characteristics and the electrical equivalent model of electric energy according to piezoelectricity, four voltage doubling rectifing circuits have as shown in figure 11 been designed, obtain a pulsating dc voltage behind the AC rectification that is used for piezoelectric vibration is produced, with this voltage via stable DC voltage of filter circuit output; Electric current charges to ultracapacitor then, and this part plays the buffering electric energy, drives DC-DC booster circuit and electric power management circuit work; Adopt DC-DC booster circuit and collection of energy circuit at last, in order to the electric weight of collecting and the storage piezoelectric produces.
The concrete operation principle of circuit is as follows:
When the voltage that comes out from piezoelectric has positive-negative polarity, diode D1 and D3 conducting, capacitor C 1 and C3 are recharged then, and virtual voltage is Vm.When polarity change timing, D1 and D3 turn-off, and C1 and C3 stop charging; The D2 conducting, the voltage on the C1 will increase, and C2 charges 2 times that reach original again.Equally, C4 also is charged to 2Vm.Because C2 and C4 can not discharge, this just makes the ultracapacitor C5 that is connected on its two ends keep DC voltage is 4Vm.In the reality, because the inevitable forward drop of each diode, the DC voltage on the C5 can not reach 4Vm completely, but very approaching.Ensuing positive half period, the electricity that the load of C2 and C4 is put replenishes by C1 and C3; This on the one hand C2 and C4 play wave filter, the wave filter that its effect is similar to rectifier reduces the ripple of output voltage.Therefore, voltage quadrupler can be finished AC-DC rectification, filtering, can increase the size of DC voltage simultaneously.
Utilize ultracapacitor to collect the electric energy that piezoelectric ceramic piece produces, Figure 12 is the complete circuit schematic diagram, can be used for being the DC circuit supply.The circuit working principle: at first, freely-supported beam type piezo-electric generating structure produce to exchange small voltage, but unstable, through four voltage doubling rectifing circuits with AC rectification for to stablize DC voltage, be stored into again among the ultracapacitor C1, as shown in figure 13.
