Description
Technical field
The utility model belongs to technical field of energy recovery, and more particularly to a kind of energy regenerating based on chattering is filled
Put.
Background technology
Mechanical vibrational energy is converted to electric energy using modes such as piezoelectric, electromagnetic induction and stores up by energy recycle device
Deposit, for example, the mechanical kinetic energy that staff swings is converted to electric energy by hand-held low energy consumption torch, be that its LED is powered, so as to need not
External cell is powered, and reduces pollution of the old and useless battery to environment, and the environment suitable for the shortage of field equal energy source.Except this it
Outward, energy recycle device also may be installed (such as water pump, engine etc.) in the reciprocating plant equipment in part, and these are set
Standby mechanical energy is converted to electric energy, so as to provide power supply for other mini-plants.
It is bigger that the internal mechanical structure of energy recycle device produces reciprocating amplitude in a cycle, its electromagnetism sense
Should be able to power or make piezoelectric produce voltage change just can be bigger, correspondingly, energy recovery efficiency is higher.Therefore, it is raising
Energy recovery efficiency, needs internal mechanical version reasonable in design so as to can produce under the incentive action of external vibration
Large amplitude.
Content of the invention
The purpose of this utility model is：A kind of energy recycle device based on chattering is provided, can be expeditiously by machine
Tool energy is converted to electric energy.
The technical solution of the utility model is：A kind of energy recycle device based on chattering, it includes:Square plastic
Box, stainless steel shell fragment, piezoelectric ceramic piece, small-sized magnet and long bar magnet；
Support is provided with square plastic magazine；One end of stainless steel shell fragment is fixed on support, and the other end is connected with small-sized
Magnet, stainless steel shell fragment constitute cantilever beam structure；Piezoelectric ceramic piece is pasted onto the side near stainless steel shell fragment fixing end, piezoelectricity
The two poles of the earth of potsherd are connected with wire；Long bar magnet is installed in the inwall of square plastic magazine, relative with small-sized magnet homopolarity；
Square plastic magazine is placed on vibration source device.
Stainless steel substrates define cantilever beam structure, are x when small-sized magnet deviates horizontal level, are produced by stainless steel substrates
Rigidity restoring force is：
In formula, x deviates horizontal distance for small-sized magnet, and E is the tension and compression rigidity of stainless steel substrates, and l is small size magnetic irony
Distance of the heart apart from stainless steel substrates between installation site on bearing.
When the small-sized magnet of stainless steel substrates end is near rectangle magnet, i.e., both spacing are Δ, then small-sized magnet
In the diagram non-linear repulsive force that is subject to of vertical direction it is：
In formula, η and M is respectively magnetic capacity and magnetic pole strength.Therefore, when reduction Δ so thatCan cause
F2＞ F1, so as to causing each stainless steel substrates " warpage ", which may be stablized in the A shown in Fig. 3 or B location；Δ is less, " sticks up
Song " degree is bigger." warpage " positional distance horizontal plane is respectively：
By the device in the plant equipment of vibration, it is assumed that small-sized magnet is now at location A, if equipment is produced
Impact, random or simple harmonic oscillation cause the vibration of stainless steel substrates so that the Oscillation Amplitude of small-sized magnet reaches | xA|, can cause
Stainless steel substrates jump to " warpage " position B from " warpage " position A, so as to cause each piezoelectric ceramic piece that wide-range strain occurs, to
Outer release electric energy.The two ends copper conductor of the device is connected with charging circuit, piezoelectric ceramic piece is produced by charging circuit
Electrical power storage, so as to realize energy regenerating.
Beneficial effect：The utility model " great-jump-forward " frame for movement can carry out large-amplitude vibration in the presence of excitation, special
Shi Yongyu not energy recycle device.It is somebody's turn to do " great-jump-forward " structure and magnet repulsive interaction flexing cantilever beam structure is utilized, so that cantilever beam
There is " warpage " in structure, define the nonlinear vibration subsystem with bistable fixed point.With a traditional only stable equilibrium point
Linear oscillator system different, the structure has two stable " warpage " positions, when external vibration incentive action is subject to, hangs
Arm beam can be from one of them " warpage " position rapid " jump " to another " warpage position ", so as to make large amplitude at short notice
Motion, if posting piezoelectric in cantilever beam end, this " jump " phenomenon can make piezoelectric have big strain amplitude, lead
Voltage change amplitude is caused to become big, the efficiency for being converted to electric energy can increase.
