Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further illustrated, but protection scope of the present invention is also
It is not limited to this.
Fig. 1 show a kind of embodiment of generated output of the present invention adjustable electromagnetic vibration energy catcher.Institute
State generated output adjustable electromagnetic vibration energy catcher, including two energy conversion devices 4, guide rail 5, mass 2, two
Drive magnet 3, described mass 2 is assemblied on guide rail 5, and two drive magnets 3 are separately fixed at two sides that mass 2 is relative
On face, the both sides being arranged on mass 2 of two energy conversion device 4 symmetries, relative with two drive magnets 3 respectively.Described
Energy conversion device 4 is fixed on adjustable platform 1, and described adjustable platform 1 can regulate energy conversion device 4 and drive magnet 3
Between distance.Operation principle according to spring mass model of vibration: amplitude is the biggest, the electric energy of generation is the biggest.When energy is changed
Distance hour between device 4 and drive magnet 3 is big, by the amplitude of moving magnet 6 with the active force of drive magnet 3 by moving magnet 6
Greatly, the electric energy now produced is big.When the distance adjusted between energy conversion device 4 and drive magnet 3, by moving magnet 6 with drive
The active force of moving magnet 3 changes with distance change, thus the electric energy ability produced changes, and reaches to adjust described electromagnetic type
The purpose of the generated output of vibrational energy collector.
As shown in Figure 4, the energy conversion device 4 described in the present embodiment by coil 8, be placed in coil 8 by moving magnet
6, by between moving magnet 6 and drive magnet 3 and be fixed on and constituted by the beryllium copper reed 7 of moving magnet 6 one end.Described driving magnetic
Ferrum 3, can be magnetic pole of the same name or synonyms pole by moving magnet 6.The coefficient of elasticity of beryllium copper reed 7 is up to 130GPa, with beryllium copper spring
Sheet 7 replaces common spring, can reduce the volume of energy conversion device 4, and conversion efficiency is high.Described mass 2 with lead
The cooperation of rail 5 uses point cantact, as shown in Figure 6, concrete, is inlaid with ball 9, ball 9 and the cunning of guide rail 5 on mass 2
Groove point cantact, change sliding friction is rolling friction.The material of ball 9 is steel, and the material of guide rail 5 is aluminum, both rolling friction
Coefficient μ=0.005, reduces frictional force suffered in motor process, shortens the generating cycle.
Specifically, mass 2 selects 20 × 20 × 14mm3Copper billet, on mass 2 drive magnet 3 select 6 × 6 ×
10mm3Nd-fe-b magnet, guide rail 5 chute select a length of 71mm aluminum, coil 8 by the enamel-covered wire of a diameter of 0.05mm around
Becoming, the number of turn is 1500 circles；A height of 40 × 40 × 1mm of beryllium copper reed 7 length and width3；6 × 6 × 5mm is selected by moving magnet 63Rubidium ferrum boron
Magnet.
The selection of adjustable platform 1 is that the size of the parts according to design determines, according to the size of above-mentioned parts,
Selecting model is the manual adjustable platform of LX40-L, as shown in Figure 5.The parameter of the manual adjustable platform of LX40-L is as shown in table 1,
The manual adjustable platform of LX40-L can move in positive and negative both direction, positions with spiral micrometer head, and degree of regulation is high, regulates model
Enclose big.
Table 1 LX40-L manual adjustable platform parameter list
When not vibrating, mass 2 falls bottom the chute of guide rail 5, as shown in Figure 1；When extraneous vibration, mass
2 along the runner movement of guide rail 5, when mass 2 move to drive magnet 3 with during by moving magnet 6 relative position, as shown in Figure 2；
Drive magnet 3 and maximum by the active force between moving magnet 6；And when mass 2 is away from during by moving magnet 6, as it is shown on figure 3, make
Firmly disappear, be equivalent to beryllium copper reed 7 and receive periodic active force.After beryllium copper reed 7 is disappeared by active force, it is subject to
Compel vibration, cause the magnetic flux in coil 8 to change, thus produce electric energy according to the law of electromagnetic induction.The size of active force
Depend on drive magnet 3 and by the distance between moving magnet 6, by two adjustable platform 1 adjustable ranges on base, regulation effect
Power, thus reach to regulate within the specific limits the effect of generated output.
As the modification of the present embodiment, described energy conversion device 4, drive magnet 3, adjustable platform 1 be alternatively one or
Multiple, drive magnet 3 is fixed on mass 2, and energy conversion device 4 and adjustable platform 1 should be respectively provided at and drive magnet 3 phase
To position.
Above-described embodiment be the present invention preferred embodiment, but invention be not limited to above-mentioned embodiment, do not carrying on the back
In the case of the flesh and blood of the present invention, those skilled in the art can make any conspicuously improved, replace or
Modification belongs to protection scope of the present invention.
