Wear multiple loop coils 21 of the second loading plate 2 setting；Loop coil 21 is also distributed in a ring on the second loading plate 2, and
In annular where the distribution of loop coil 21, the spacing between adjacent annular coil 21 is also equal, and in loop coil 21
In inner ring, it is additionally provided with magnetostrictor 22.
It should be noted that it is not required for being both provided with magnetostrictor in each 21 inner ring of loop coil in the present invention
22, but magnetostrictor 22 is respectively provided in each 21 inner ring of loop coil, it is capable of the output power of energization collector,
Therefore, this is a kind of more preferably scheme, in subsequent embodiment, be defaulted as being respectively provided in each loop coil 21 there are one
Magnetostrictor 22, corresponding, the distribution mode and distributing position of loop coil 21 in subsequent embodiment, it will be also be appreciated that
Equally it is the distribution mode and distributing position of magnetostrictor 22.
In addition, the first loading plate 1 and the second loading plate 2 can relatively rotate, and Pivot axle and the second loading plate 2 hang down
Directly, then, correspondingly Pivot axle is also vertical with the first loading plate 1.
Also, multiple magnets 11 and multiple loop coils 21 are equal with the distance of Pivot axle, in other words magnet 11

Piezomagnetism so that generate electric current in loop coil 21.With the relative rotation of the first loading plate 1 and the second loading plate 2, annular
Coil 21 and magnetostrictor 22 are successively by the position between the magnet 11 on two the first loading plates 1, in loop coil 21
Changing of moving in circles of magnetic flux so that loop coil 21 generates sensing electric current, and magnetostrictor 22 is at two the
It is hit back and forth between one carrying, since magnetostriction materials have piezomagnetism in itself, magnetostrictor 22 under impact force action
The interior intensity of magnetization will change, so as to generate the pressure magnetoelectricity stream of pressure magnetic power generation, final entire magnetostriction ability collector
The electrical power obtained is the superimposed current of two different electric currents.
And the driving force that the first loading plate 1 is driven to be relatively rotated relative to the second loading plate 2 is what is obtained from environment
Power, for example, the knee joint of people when on foot, has the rotary motion of certain angle, it can be by obtaining the rotary motion
Energy can also can also be by the acquisition kinetic energy that such as automotive wheel rotates and obtain vibration in environment, extruding or other forms
Energy.
For piezoelectric ceramics energy collector of the prior art, in the present invention be based on magnetostriction materials and
The energy collecting device of design, magnetostriction materials are with machine magnetic coupling coefficient is big, load capacity is strong, energy density is high, conversion effect
The advantages that rate is high.The second loading plate 2 is driven to be rotated relative to the first loading plate 1 by the energy got in the present invention, then
Accordingly, magnetostrictor 22 is made to generate piezomagnetism so as to obtain electric current, while also passes through the magnetic flux in loop coil 21
Variation generates electric current, takes full advantage of the first loading plate 1 and the kinetic energy of the second loading plate 2 rotation, makes to obtain in loop coil 21
Electric energy that two kinds of different approaches of piezomagnetism and electromagnetic induction generate improves the energy transformation ratio and electric energy of energy collecting device

Under the premise of energy, there is smaller volume, more adapt to wireless sensor and MEMS to energy collecting device small size, be convenient for
Integrated requirement.
Based on above-described embodiment, in order to improve the energy transformation ratio of magnetostriction energy collecting device to the full extent, at this
In the another specific embodiment of invention, it may further include：
The quantity of magnetostrictor 22 is twice of 11 quantity of magnet on each first loading plate 1, then adjacent mangneto
The half of spacing of the spacing between adjacent magnets 11 on each first loading plate 1 between extrusome 22, also ensures that
When a magnetostrictor 22 is adsorbed when on some magnet 11, while equal on each magnet 11 on two the first loading plates 1
Absorption not have there are one magnetostrictor 22, without there are the corresponding magnets 11 in position between certain two magnetostrictor 22
Magnetostrictor 22 is adsorbed, there is the magnetostrictor 22 for applying impact force this guarantees the magnetic field that each magnet generates,
Also all there is the loop coil 21 changed corresponding to 21 magnetic flux of loop coil, from having played each magnet 11 to the full extent
Effect so that the Current Output Power in loop coil 21 is maximum, improves energy transformation ratio.
Based on above-mentioned any embodiment, in the another specific embodiment of the present invention, can further include：
Magnet 11 is the magnet 11 with fan shaped cross section, since fan-shaped magnet structure center leakage field is less, is easy to magnetic
The design of uniform magnetic field in extrusome 22 is caused, the fan shaped cross section is parallel with the plane where the first loading plate 1, and the sector is horizontal
The center of circle of the fan-shaped arc in section is located in Pivot axle, in order to reduce the body of energy collecting device in actual application
Product, magnet 11 is generally using the magnet 11 of fan-shaped platy structure.For set there are two the first loading plate 1 energy collecting device and
Speech, 11 thickness of magnet of the sector plate is usually fan-shaped arc identical with the thickness of the second loading plate 2 and fan shaped cross section
The center of circle be located in Pivot axle；
Further, it is contemplated that when the cross section of loop coil 21 is too small relative to the cross section of magnet 11, Ke Nengcun
When loop coil 21 and magnetostrictor 22 are moved relative to magnet 11, when slipping over the position of face magnet 11, if magnet
11 cross sections are excessive, then and loop coil 21 and magnetostrictor 22 are being slided relative to magnet 11 within very big one section of radian,
The magnetic flux of present position does not change, then also just greatly reduces the output power of electric current.It is, whereas if annular
The cross section of coil 21 is much larger than the cross section of magnet 11, then, it is understood that there may be 21 face of magnetostrictor 22 and loop coil
The position distribution on the first loading plate 1 has multiple magnets 11, when magnet 11 is relative to magnetostrictor 22 and loop coil 21
During rotation, piezomagnetism and electromagnetic induction phenomenon hardly occurs, therefore, the size of loop coil 21 should be with the size of magnet 11
Match, loop coil 21 can be the making toroidal coil 21 with circular cross section, the cross-sectional area of loop coil 21 and
The ratio of 11 cross-sectional area of magnet can be 0.65~0.75, it is however generally that area ratio is arranged on 0.7 or so so that
Even if the first loading plate 1 and the second loading plate 2 have the relative rotation of very little angle, electric current can be also generated in loop coil 21.
It is possible to further which setting is every magnetic patch 13 between two closest magnets 11, because magnet 11 is transversal
Face is fan shaped cross section, and cross section is parallel with 1 place plane of the first loading plate, it is possible to set the shape every magnetic patch 13 big
It is small identical with the shape size of magnet 11, it is to limit magnet 11 to be in specific on the first loading plate 1 every the main function of magnetic patch 13
Position keep stablizing and fix, and the component between adjacent magnet 11 is magnetized in order to prevent, so using having not by magnetic
The characteristic of change every magnetic patch 13.
It should be noted that generally directly multiple through-holes can be set on the first loading plate 1, magnet 11 is arranged on logical
In hole, and between adjacent magnet 11 be every magnetic patch 13 first loading plate 1 a part, in other words every magnetic patch 13 and the
One loading plate, 1 ontology is structure as a whole, and it is split to be also not precluded in the present invention certainly every 13 and first loading plate of magnetic patch, 1 ontology
The embodiment of structure.
Further, it for non-magnetic first loading plate 1 and chromium Nitinol may be used every magnetic patch 13 is made, in reality
In the application process of border, the second loading plate 2 is also often to be made of with not magnetizable un-conducted magnetic material, therefore the second carrying
Plate 2 can also be the non-magnetic loading plate of chromium Nitinol.

Surface, but adsorb on the surface of magnetic isolation plate 12, and magnetic isolation plate 12 is close to the coefficient of sliding friction on the surface of the second loading plate 2
No more than default friction coefficient.
If it should be noted that magnetic is completely fitted in by the attraction of magnet 11 in view of magnetostrictor 22
The surface of body 11, then, when need drive the second loading plate 2 relative to rotated with the first loading plate 1 when, may be stretched due to mangneto
Frictional force between contracting body 22 and magnet 11 and the mechanical energy for consuming part, lead to the problem of too low to the conversion ratio of energy.
Therefore, magnetic isolation plate 12 is set on the first loading plate 1, it can be in advance to magnetic isolation plate 12 close to magnetostrictor 22
Surface is processed by shot blasting, its friction coefficient is made to be no more than 0.2, forms a smooth surface, then when 2 phase of the second loading plate
When being rotated for the first loading plate 1, even if magnetostrictor 22 and magnetic isolation plate 12 are bonded more closely, it will not be lost excessive
Mechanical energy so as to reduce the loss of energy, improves energy conversion efficiency.
Further, in order to avoid magnetic isolation plate 12 is blocked up, the magnetic field of the generation of magnet 11 is influenced to loop coil 21 and mangneto
