Technical field
The present invention relates to a kind of vibration generating device.
Background technology
To wireless sensor network or distributed mini system powerup issue is a difficult point.And vibration is natural a kind of energy existence form.The wave on sea for example, branch swing in the wind, jarring vehicle etc.Vibrating power-generation is that the Conversion of energy that various vibrations are produced is an electric energy, is a kind of potential pollution-free, novel power generation device of consumption of natural resource not, is suitable for wireless sensor network or distributed mini system node and adopts.
A kind of mode that realizes vibrating power-generation is the electromagnetic induction phenomenon generating.Electromagnetic induction vibration generating device in the past, internal structure has nothing in common with each other.Application number is 200410067821.3 vibrating electricity generator; Application number is 200810230833.1 three-dimensional vibrating electricity generator, and application number is 200710126703.9 portable vibration generator, and application number is 200610051677.3 magnetic-field extrusion reinforced vibration generator; Paper " research of novel permanent magnetic body external straight-line oscillation generator performance " (journal of Zhejiang university engineering version; The 41st the 9th phase of volume, pp.1604-1608) and paper " A micro electromagnetic generator forvibration energy harvesting " (JOURNAL OF MICROMECHANICS ANDMICROENGINEERING, 17 (2007); Pp.1257-1265); On its structure, all cannot say for sure to demonstrate,prove the less requirement of air gap in the magnetic circuit, fail to realize closed magnetic circuit, can know that by the relevant theory of motor its magnetic flux density is low; The magnetic circuit utilance is not high, and the vibrational energy utilance is not high.Simultaneously the coil utilance also is one and can improves part in above-mentioned some data, has in its coil than the effective cutting magnetic line of many parts, and the generation electromotive force influences generating efficiency.
Summary of the invention
It is low and improve the problem of coil utilance that the present invention will solve existing vibration generating device magnetic circuit utilance, provides a kind of magnetic circuit utilance high encircling type vibration generating device.
Technical scheme of the present invention:
Encircling type vibration generating device; Comprise shell, said shell is provided with lid, it is characterized in that: be provided with flower shape bonded permanent magnet in the said shell; The centre of said bonded permanent magnet is a square N utmost point; The said N utmost point is wound with four S utmost points all around, and the said S utmost point is cross and is symmetrically distributed, and its bottom links together and is connected with the N utmost point; Between the said N utmost point and the S utmost point, coil is installed; Said coil upper/lower terminal is provided with square deck framework; The other end of said upper and lower deck framework has connected spring; Said deck framework down is enclosed within N and extremely goes up, and said lower spring lower end is connected in the bottom of the S utmost point, and said upper spring upper end is fixed on the lid.
Further, said shell is a cylindrical structure.
Further, said bonded permanent magnet is ferrite permanent-magnet materials or rare earth permanent-magnetic material powder and plastics or rubber mix is moulding forms.
Further, said spring is a plastic material.
Further, the bottom of the said S utmost point is provided with cascade groove, is fixedly connected with vertical lower spring on the said groove.
Further, said S is coated with the first ferromagnetic material bed course on extremely, is provided with the fixedly rubber washer of usefulness between said first ferromagnetic material bed course and the lid, and the first ferromagnetic material bed course is fixed on S by lid through rubber washer and extremely goes up.
Further; The said N utmost point is coated with the second ferromagnetic material bed course; Four sides of the second ferromagnetic material bed course are provided with first groove, are provided with ball in said first groove, and the diameter of said ball is greater than the degree of depth of first groove; Its radius is less than the degree of depth of first groove, and the lateral surface of said ball contacts with coil.
Further, said ball is a ferromagnetic material.
Perhaps, said ball is the duralumin material.
The magnetic line of force to evenly dispersing, passes the second ferromagnetic material bed course that N extremely goes up by the N utmost point on the axis all around among the present invention, and through air gap, the first ferromagnetic material bed course through S extremely goes up turns back to the N utmost point through the S utmost point, forms closed main magnetic circuit.The extremely surperficial ferromagnetic material bed course that all covers suitable thickness of the N utmost point, S on the one hand, has reduced magnetic resistance thereby reduced air gap, can obtain bigger magnetic flux density; Be convenient to the installation of bottom spring on the other hand.Only through an air gap, only contain one deck coil wall in the air gap in the closed main magnetic circuit.The thickness of this coil wall is for confirming the key factor of width of air gap.The minimum diameter of standard paint envelope curve is 0.015mm; Suppose that width of air gap is 0.5mm; And the thickness of coil wall is 0.35mm, and supposes that the ferromagnetic material bed course is of a size of 10mm on the direction of coil up-down vibration, and the part that can cut the main magnetic circuit magnetic line of force in the coil can reach more than 14000 circles.Can guarantee that so promptly width of air gap is very little in the main magnetic circuit, improve the magnetic circuit utilance; And coil turn is higher, to obtain higher electromotive force.
In vibration processes, spring up-down stretch or compression make the coil downward cutting magnetic line that makes progress.When coil made progress cutting magnetic line, four limits of coil all produced counterclockwise electromotive force, can superpose in the same way, have improved total electromotive force; When the downward cutting magnetic line of coil, four limits of coil all produce clockwise electromotive force.So just produced alternating current, thereby generated electricity.But so 4 equal cutting magnetic lines of coil, and the electromotive force of 4 generations do not offset but superposes, and the coil utilance is high.
Ball among the present invention can guarantee that the coil and the second ferromagnetic material bed course keep certain distance, and it is more level and smooth that it is moved up and down, and improved the efficient of vibrating power-generation.Ball can be processed by ferromagnetic material or duralumin material.The ferromagnetic material advantage: the one, can be pull-in on better in the groove, be convenient to install; The 2nd, can reduce air gap in the part, raise the efficiency.And its shortcoming is the frictional force in the time of can increasing rolling owing to the magnetic force between ferromagnetic material and ball, and this just needs through processing raising surface flatnesses such as polishing grindings, in the hope of reducing rubbing action.The duralumin material does not have the adhesive effect, and frictional force is little during rolling, but does not have the benefit that reduces air gap yet.
Beneficial effect of the present invention: improved the utilance of magnetic circuit, improved the coil utilance, improved generating efficiency; And its compact conformation, applied widely.
