Description

Spring magnetic oscillator reciprocating resonance generator

The utility model relates to a kind of motor that movable magnet and stationary coil system are arranged.

Motor commonly used generally all includes stator and rotor, this type of motor or by rotor rotation and cutting magnetic line is converted to electric energy with mechanical energy; Or by the variation magnetic field work done makes rotor rotation to rotor, convert electrical energy into mechanical energy.Therefore the rotation of rotor is that this class motor is realized the requisite condition of power conversion.But the kinetic energy of object linear reciprocating motion need be converted to electric energy in some application scenario or convert electric energy to the kinetic energy of linear reciprocating motion form, the use of above-mentioned motor commonly used just has certain limitation.Chinese patent CN2112226U has announced a kind of solenoid type motor, and it includes solenoid, hollow pipe and carries magnet, and solenoid is enclosed within on the hollow pipe shell with solenoidal form.In hollow pipe, place and movably carry magnet more than one or one.Though this motor has overcome the limitation of electric rotating machine in some application scenario, and has simple in structure, compact advantage, a very big shortcoming is arranged, that is exactly that energy conversion efficiency is low.This be since this motor carry magnet when reciprocating, the conversion of its direction of motion can only outer power realize carrying the magnet acting, therefore causes the loss of carrying the magnet energy.In the CN2112226U patent, the magnetic flux in the solenoid body is too little in addition, and good big a part of coil does not have magnetic flux, makes this part coil not produce induced electromotive force, thereby has caused the waste of material.

The purpose of this utility model just is to overcome the deficiency of existing reciprocable machine, the reciprocable machine of provide a kind of energy conversion efficiency height, simple in structure, stable working, realizing easily.

According to Faraday's electromagnetic induction law, the induced electromotive force of closing coil is directly proportional with the rate of change of the magnetic flux that passes this coil.Therefore, change, will in coil, produce electric current as long as pass the magnetic flux of closing coil.For reciprocating energy is transformed into electric energy, and have higher energy conversion rate, can take a kind of like this structure: magnon is placed in the hollow pipe coil on the hollow pipe overcoat.And on the two sides of magnon fixing upper spring respectively, the other end of two springs is separately fixed on the end face of hollow pipe.Constitute a resonator system by spring, magnon like this.When the interfering frequency of double vibrations external force and this resonator system natural frequency were close, magnon was in resonance state, thereby constantly mechanical energy is converted to the electric energy in the coil.When adding the alternating voltage that a frequency and resonator system natural frequency are close to coil, this resonator system also will produce resonance, and magnon is in a kind of continuous reciprocating motion state, thus the mechanical energy of converting electric energy to.

In structure of the present utility model,, a kind of energy storage and delivery system also promptly are provided, thereby have avoided the loss of magnon energy substantially, so energy conversion efficiency is quite high owing to introduced spring system.Simultaneously, the utility model advantage of also having simple in structure, stable working, realizing easily.

As shown in Figure 1, magnon (2) constitutes by equidistant arrangement several years of magnet (1) in the cylindrical shell of two ends sealing.The polarity of carrying magnet is relative in twos, the relative magnetic pole of both adjacent year magnet always S extremely to the S utmost point or N extremely to the N utmost point.In order to guarantee to carry the position relative fixed of magnet (1) in the magnon cylindrical shell, can between year magnet, add centring ring (4), can certainly add the filler of non-magnetic conduction at two years between magnet, fix the position of carrying magnet.Year magnet in the magnon can be one, also can be a plurality of.On the magnon shell, be fixed with coil (3).When magnon in the middle of the coil during reciprocating motion, thereby the conversion that will in coil, produce electric current realization energy.If when in the magnon a plurality of years magnets being arranged, the width of coil preferably equals the adjacent year distance between the magnet adjacent face.Just as shown in Figure 1, under such condition, the electromotive force composite wave that year magnet № 1, № 2, № 3 are produced on coil (3) is that excitation superposes.Define adjacent year distance between the magnet adjacent face and add that to upload the magnet width be pitch, so, the width of coil should be less than or equal to pitch, is the excitation stack to guarantee to carry electromotive force that magnet contributed coil.

And for example shown in Figure 2, in order to increase the induced electromotive force of output, can on the shell of magnon (2), increase a coil again, the width of two coils (3) preferably equates.And a coil is set in the pitch, and the width of coil is less than or equal to pitch.Can take such scheme to being provided with of two above coils: in magnon centromere distance, a coil (3) is set, in each pitch of both sides, arranges remaining coil at centromere.Like this, can reach the purpose that increases the output induced electromotive force, and avoid in each coil induced electromotive force to cancel out each other or part is cancelled out each other.At this moment, the magnet (1) that carries in the magnon preferably has a plurality of.

As shown in Figure 3, magnon (2) is positioned at hollow pipe (8), and its two ends are fixed with spring (7).Position-limited rack (6) also is housed, to limit the amplitude of magnon in the hollow pipe two ends.In the magnon equidistantly row have and carry a magnet (1), adjacent year magnet pole polarity close to each other is identical, and carries between magnet and located by centring ring (4).The two ends of hollow pipe are bolted with end cap (5).Coil (3) is positioned on the hollow pipe (8), and fixing by spacing ring (9).

The structure of reciprocating vibrating type motor is referring to Fig. 4.The magnon of this motor carries magnet (1) by one and constitutes.Be fine with a plurality of years magnets and a plurality of coil, but the amplitude of motor can not surpass a pitch yet.Be fixed with spring (7) at the two ends of magnon, the other end of two springs is separately fixed on two terminations of hollow pipe.The two ends of hollow pipe also are fixed with position-limited rack (6), with the amplitude of restriction magnon.For the transmission arm (10) that is fixed on the magnon can be drawn, circumferentially have three on the hollow pipe housing symmetrically with upper shed in hollow pipe (8).Also be fixed with coil (3) on the hollow pipe housing, this coil is fixed by spacing ring.When passing to the approaching alternating current of frequency and system frequency in the coil, will cause the resonance of magnon, thereby produce double vibrations at the transmission arm exit.
