Description
Technical field
The invention belongs to electromagnetism class energy recuperation field, particularly a kind of multi-direction vibration magneto-electric energy collecting system, it has the function that the vibration mechanical energy in the external world is converted to electric energy.
Background technology
For a long time, people adopt battery powered form to the system of data collection, so not only spend certain manpower and materials and change battery, and the use of battery also can pollute environment to a certain extent.So in recent years, extract the favor that energy obtains most of people from surrounding environment, as solar energy, wind energy etc. have all obtained very fast development.The research of the collection of at present relevant vibrational energy just changes into electric energy to the vibrational energy of surrounding environment, thereby replaces traditional battery power supply system.And such system generally all is used in the circuit of low-power consumption, so also can satisfy the demand of measurement fully by the collection of environmental energy.
Electromagnetic induction claims the magnetoelectric induction phenomenon again, is meant the conductor that is placed in the change magnetic flux, can produce electromotive force.This electromotive force is called induced electromotive force or induced electromotive force, if this conductor is closed into a loop, then this electromotive force can order about the mobile induced current (induced current) that forms of electronics.We know that two conditions that induced current produces are: (1) circuit is closed and is to guarantee conducting; (2) magnetic flux that passes the closed-loop path changes.These two conditions are essential.So,,, can guarantee in the scope of this coiling group sealing, to produce certain magnetic flux when when a permanent magnet is placed on its next door for the coiling group of a sealing.Like this, when the position of this permanent magnet changes, the magnetic flux by this coiling group all will change.So just can on principle, guarantee faradic generation.
In practical project is used, in order to satisfy human various experiment demand, the layout of transducer becomes increasingly complex, for can't arrive local of the mankind and be difficult to the place that arrives, general powered battery is difficult to meet the demands, so people have considered the demand that satisfies power supply by the energy around gathering, and the present invention just is based on such background proposition.Vibrational energy is a kind of form of energy of extensive existence, even with the place that enters is all arranged existing of vibration in that many people are difficult, thereby research vibrational energy collection technique has certain meaning.
The present invention is based on the vibrational energy of magnetoelectricity technology and collects, owing to have characteristics such as simple in structure, easy to process, has use value widely in engineering.
Summary of the invention
Technical problem to be solved by this invention is at defective in the aforementioned background art and deficiency, provides a kind of multi-direction vibration magneto-electric energy collecting system, its existing relatively energy-recuperation system, has firmer structure, applied range, the efficiency of energy collection height, manufacture craft is simple.
The present invention is for solving the problems of the technologies described above, and the technical scheme that is adopted is:
A kind of multi-direction vibration magneto-electric energy collecting system, comprise cube frame, magnetic element, flexible member and six planar coils, cube frame is fixed in shaking platform, magnetic element is positioned at the center of cube frame, and is connected respectively with each summit of cube frame respectively by flexible member; Planar coil all has independently tap, is connected with the electric energy recovery circuit respectively, is individually fixed in six outer surfaces of cube frame.
Above-mentioned permanent magnet is cylindrical structure or rectangular structure.
Above-mentioned planar coil is made by the little copper core of resistivity.
The number of turn of above-mentioned six planar coils is identical.
After adopting such scheme, the present invention will vibrate induction element and energy conversion component is combined, the vibration induction element mainly is meant cube frame, and it is fixed on the shaking platform in the environment, just can be transferred to the vibrational energy of outside in the energy collecting system of the present invention; And energy conversion component mainly is made up of magnetic element and planar coil, and by their relative motion, the variation of the magnetic flux in the space will produce a certain amount of induced current.Like this, extraneous vibrational energy has converted the relative motion of cube frame and magnetic element to by cube frame, and planar coil is cemented on the cube frame, so the relative motion of magnetic element and cube frame will produce induced current on planar coil, this has just finished from the transfer process of vibration mechanical energy to electric energy.

Embodiment
Below with reference to the drawings, the present invention is described in further detail.
Cooperate Fig. 1 to shown in Figure 3, the invention provides a kind of multi-direction vibration magneto-electric energy collecting system, comprise cube frame 3, magnetic element 2, flexible member 1 and planar coil 4, introduce respectively below.
As shown in Figure 3, cube frame 3 has 6 outer surfaces, 8 summits; Magnetic element 2 is cylindrical structure or rectangular structure, be positioned at the inside center of cube frame 3, and be connected with each summit of cube frame 3 respectively by flexible member 1, can guarantee that like this magnetic element 2 satisfies multidirectional vibration under the constraint of flexible member 1; And the quantity of flexible member 1 is corresponding with the summit number of cube frame 3, and 8 flexible members 1 are connected with 8 summits of cube frame 3 respectively, constitutes symmetrical structure.
The concrete course of work of the present invention is: cube frame 3 is cemented on the shaking platform, when there is vibration in the external world, the vibration of cube frame 3 fastest responses, because the existence of inertia, magnetic element 2 remains unchanged, and between cube frame 3 and magnetic element 2 relative motion has just been arranged like this, displacement has also just been arranged, and on the present flexible member 1 of this offset table, some is stretched just to represent flexible member 1, and another part then is compressed.Suppose the words that this vibration stops at this moment, cube frame 3 also will stop so, thereby fixed also stop motion of planar coil 4 thereon, but the flexible member 1 in the cube frame 3 but still is in nonequilibrium state, flexible member 1 will continue driving magnetic element 2 sustained vibrations this moment, until stopping.So just can guarantee, as long as the external world has vibration to produce, so by the present invention, just can change into the relative motion of magnetic element 2 and planar coil 4, magnetic flux on planar coil 4 also will change like this, equally also just produce induced current, just finished the function of from external environment, extracting electric energy in conjunction with outside electric energy recovery circuit again.
The invention has the advantages that: the first, can maximumly gather outside vibrational energy, because cube frame 1 is consolidated with the external vibration platform with limiting the quantity of; The second, energy loss is less, and this is that the vibrational energy of any like this direction can both be collected because inner magnetic element 2 can the multi-direction vibration in the space; The 3rd, structure and technology are simple, need parts few.
Above embodiment only for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of being done on the technical scheme basis all falls within the protection range of the present invention.
