Description

Modular generator using vibration energy and power generation method using the modular generator {module type electric generator and the electric generating method using vibration energy}

The present invention relates to a generator to obtain electricity by vibrating a coil in the magnetic field after forming a magnetic field using a magnet, and more particularly, the coil located between two magnets is transmitted to the vibration transmitted from the outside. By shaking and vibrating together for a high efficiency modular generator, characterized in that to generate electricity.

A generator is a device that converts mechanical energy into electrical energy and generally uses electromagnetic induction. It converts potential energy or thermal energy of water into rotational energy and collects electric current generated by rotation between magnet and coil to obtain electricity.

The device for converting the double vibration energy into electrical energy is a device that obtains electricity by changing the position of the coil with respect to the magnetic field by vibrating one or both of the magnet and the coil, and can be provided in a smaller size than a general generator. .

Looking at the structure of the generator using the conventional vibration energy, patent application No. 041415, the coil is wound around the outer peripheral side of the center of the cylindrical case and the magnet is positioned in the center of the inner space of the housing by an elastic member such as a spring, vibration in the housing When this is applied, the magnet is vibrated inside the housing and a technical idea is disclosed to induce a current to flow in the coil as the magnetic field is shaken. Patent application No. 21385 discloses that the most magnetic force is generated in the centrally located magnet The technical idea of winding coils in the positions of the outer housings corresponding to the positions of the north pole and the south pole is disclosed, and Utility Model Application No. 21170, 2004, attaches magnets to both ends of the cylindrical housing and is located therebetween. When the inner magnets face the same poles as the magnets at both ends, the inner magnets Disclosed is a technical idea to be located in the center of the housing without colliding with the magnets at both ends.

However, the generator using the existing vibration energy was difficult to obtain satisfactory results in terms of efficiency, and mainly manufactured in a small size, and in the case of using a magnet, a permanent magnet having weak magnetic force was used rather than an electromagnet. This is because the winding is inefficient in increasing the winding number N of the coil.

In particular, when a plurality of existing vibration generators in which a magnet vibrates to increase the amount of power generation is configured, the magnet in the generator is affected by the magnetic force of other generator magnets, the movement is limited, the power generation efficiency decreases.

On the contrary, in the vibrating generator in which the coil vibrates, the coil is wound inside the housing, thereby effectively increasing the number of windings of the coil. Even when a large number of generators are arranged, the coil's movement is not affected by the magnetic force, and thus the generation efficiency is lowered. The problem does not occur.

The present invention has a purpose of providing a modular generator for generating electrical energy more efficiently by further improving the structure of the generator using the vibration energy in the generator for generating electrical energy using vibration energy.

Hereinafter will be described in detail with reference to the accompanying drawings the specific embodiments and experimental results that preferably implement the technical spirit of the present application.

1 is a perspective view showing the appearance of the modular generator provided herein, the appearance of the modular generator 10 provided herein is similar to the general battery shape. The generated electricity is installed as a positive electrode 11 and a negative electrode 12 (shown in FIG. 2A) at the top and the bottom of the generator, respectively, to send current to the outside, and the sent current is stored in a separate charging device (not shown). It becomes possible.

The appearance of the generator does not necessarily have to follow the shape of the general battery, but there is an advantage that the user can be used in series or in parallel by accustomed to the appearance of the common battery that is used a lot in real life.

Figure 2a is an internal perspective view showing the basic internal structure of the generator of the present application, Figure 2b is a cross-sectional view thereof.

The case 15 constituting the outer shape of the generator is provided in a cylindrical shape with the top and bottom bored, magnets 20A and 20B are located at the top and bottom of the case, respectively, and a magnet fixing part for fixing the magnet to the case ( 21A and 21B are installed in a structure in which a magnet is built, and a vibration part 40 in which a coil 41 is wound is positioned at a center inside the case between the magnet fixing parts 21A and 21B, but the vibration part is a magnet fixing part. And springs 50A and 50B, respectively.

The case 15 is usually provided in a cylindrical shape, but may also be provided in the shape of a polygonal cylinder, and the appearance of the magnets 20A and 20B, the magnet fixing parts 21A and 21B, and the vibrating part 40 may include the case. According to the appearance, the case is provided in the form of a cylindrical cylinder, and a polygonal cylinder in the case of a polygonal cylinder.

In this case, if the case 15 is configured to act as a magnetic field shielding film, the magnetic field does not extend to the outside and the effect is concentrated inside the generator.

That is, when the magnetic field shielding film is formed by plating or coating permallo or sendust on the inner surface of the case, the influence of the magnetic field can be minimized to the outside.

Permanent magnets are used for the magnets 20A and 20B, and in particular, the same poles are disposed between the two magnets 20A and 20B. As shown in FIG. 2, the S poles of the magnets face each other from the top to NS-SN, or the N poles of the magnets face each other with SN-NS, so that repulsive force is generated between the two magnets.

When repulsive force is generated between the two magnets, the magnetic fields are pushed to each other at the position of the central vibrator 40 between the two magnets so that more current can flow when the vibrator on which the coil is wound vibrates.

The magnet fixing parts 21A and 21B are installed to have magnets embedded therein and fixed to upper and lower ends of the case. The magnet fixing part can open the cap 22 in the form of a hollow cylinder to put the magnet inside and close the cap to embed the magnet. Also, the cap 22 has a spring fixing part 23 formed in a convex manner to fix the spring. It is desirable to be able to.

The vibrator 40 is connected to the magnet fixing part and the spring (50A, 50B) is located at the position of the center of the case (15). Coil 41 is wound in the center of the vibrator, although not shown, one end of the coil is connected to the anode 11 at the top of the case and the other end is connected to the cathode at the bottom of the case to send out electricity generated to the outside. Configured to do so.

In addition, it is preferable that the spring fixing part 42 is formed to be convex to the upper and lower portions of the vibrator 40, respectively, to fix the spring.

The springs 50A and 50B are positioned between the magnet fixing part and the vibrating part and are fitted to the spring fixing part 23 of the magnet fixing part and the spring fixing part 42 of the vibrating part, respectively, to prevent separation. The two springs 51A and 50B are preferably made of the same spring so as to have the same spring constant, length, and size.

Figure 2c is an exploded perspective view of the internal structure excluding the case, Figure 2d is an assembled perspective view of the modular generator internal components assembled. Between the two magnets 20A and 20B, the vibrator 40 wound around the coil 41 moves by the vibration transmitted from the outside, so that a current flows in the coil, thereby generating electricity, and the springs 50A and 50B. By vibrating unit can freely reciprocate up and down.

However, the movement of the vibrator due to external vibration not only moves up and down, but also moves from side to side. Also, the spring may be pulled out by a strong shock or vibration, and in order to obtain electricity with higher efficiency, the vibrator only moves up and down. It needs to be able to move and prevent the spring from coming off.

Figure 3 shows the internal structure of the modular generator with the shaft added, Figure 3a is an internal perspective view and Figure 3b is a sectional view. A shaft support portion 24 for supporting the shaft is further formed in the caps 22A and 22B of the magnet fixing portion, and the shaft 30 penetrates the vibrating portion 40 so that the magnet fixing portion 21A at the top and the magnet at the bottom are fixed. It is configured to connect the fixing portion 21B. At this time, it is preferable that the shaft 30 is located at the position of the central axis inside the case.

In the modular generator further configured with a shaft 30, the vibration unit 40 can only move up and down to generate electricity more efficiently, and can prevent the departure of the spring to increase the durability of the product.

In particular, when the shaft 30 is made of a ferromagnetic metal material such as iron, the magnetic field passing through the vibrating portion may be more concentrated.

FIG. 4 is a cross-sectional view showing a structure in which a ferromagnetic shaft 31 made of metal is in contact with a magnet, and a hole is drilled in the center of the cap 22 of the magnet fixing parts 21A and 21B. The end has shown the structure which abuts adjacent to each magnet 20A, 20B.

Figure 5 is an exemplary view illustrating a method of preferably connecting in series or in parallel when a plurality of modular generators of the present application. When connecting a plurality of generators of the present invention, it is preferable to connect the generator of different types in series / parallel. That is, when another generator is connected in series or parallel to the generator (SS generator, 10S) arranged so that the S pole of the magnet faces each other, the generator connected by connecting the generator (NN generator, 10N) arranged so that the N pole of the magnet faces each other. It can reduce the interference between magnetic fields inside the generator while preventing repulsion from occurring in the liver.

In addition, the electricity produced by the modular generator is to be sent to and stored in the charging device 60 provided separately from the outside. At this time, by connecting the modular generator of the present application in series and / or parallel indicates that the characteristics of the charging device, the maximum charging limit and the charging time can be freely adjusted.

6 to 8 show the results of the analysis simulation of the magnetic field according to the magnet array, attached to show how effective the modular generator using the vibration energy of the present application.

FIG. 6 is a graph analyzing magnetic fields between two magnets 20A and 20B in a state in which there is no ferromagnetic axis. FIGS. 6A and 6B are graphs of magnetic field analysis in a state in which different poles face each other (NS-NS). 6c and 6d are graphs of magnetic field analysis in the state where the same poles face each other (NS-SN).

In the state facing the different poles as shown in FIGS. 6A and 6B, the magnetic field is convexly floating in the center of the generator where the vibration unit is located, and thus the vibration unit is not located in the magnetic field. Although the power generation efficiency is low due to the small change of, the magnetic field lines are relatively changed when the vibration part wound around the coil moves in the center in the state that the magnetic field inside the generator changes rapidly in the center as shown in FIGS. 6C and 6D. It can be seen that much larger.

However, since the line of magnetic force is bent out before reaching the center of the vibrating portion, it is difficult to effectively produce electricity when the vibrating portion vibrates small.

FIG. 7 is a graph comparing and analyzing a state of a magnetic field which is changed by connecting or not connecting a ferromagnetic axis between two magnets 20A and 20B.

FIG. 7A is a magnetic field analysis graph when the polarities of the magnets are arranged opposite to each other (NS-NS) in the absence of the ferromagnetic axis, and FIG. 7B is the same as that of FIG. 7A, in which the magnets are arranged and the ferromagnetic axes are connected. As a graph of magnetic field analysis in a state, when the poles are arranged to face each other, the magnetic field lines inside the generator form a uniform straight line when there is a ferromagnetic axis, and thus the power generation efficiency is lower.

In other words, when the magnets face different poles, the magnetic field is concentrated toward the vibrating part by the ferromagnetic axis, but the vibration direction and the magnetic field direction are parallel to the vibrating part. do.

FIG. 7C is a magnetic field analysis graph when the poles of the magnets are arranged to face each other with the same polarity (NS-SN) in the absence of the ferromagnetic axis. FIG. 7D is the same as that of FIG. 7C. As a magnetic field analysis graph in the state, it can be seen that the rapid magnetic field change occurs at the central position by guiding the magnetic field lines in which the ferromagnetic axes are dispersed to increase the power generation efficiency.

That is, when repulsive force occurs when facing the same poles, the magnetic field is concentrated toward the vibrating part by the ferromagnetic axis, and the magnetic field is formed in the direction perpendicular to the vibrating direction of the vibrating part at the center of the shaft, so that the magnetic field changes according to the vibration of the vibrating part. It can be seen that the generation efficiency is very large.

As a result of the above simulation, the modular generator of the present invention, in which two magnets face each other with the same poles and a ferromagnetic shaft is connected between them, and a vibrating portion in which a coil is wound between the two magnets, is vibrated by a spring. It is high.

FIG. 8 illustrates why it is preferable to connect generators of different types as in FIG. 5 when the modular generators of the present application in which the ferromagnetic shaft is further configured are connected in series.

FIG. 8A is a state in which generators of the same type are connected in series, that is, a magnetic field is analyzed when two generators facing each other with S-poles are arranged in series. FIG. 8B is a state in which other generators are connected in series. In other words, the magnetic field is analyzed when one generator in which S poles face each other and one generator in which N poles face each other are arranged in series.

As shown in FIG. 8A and FIG. 8B, in both cases, a magnetic field is formed at a center position of the ferromagnetic shaft where the vibration unit is to be located so as to be perpendicular to the vibration direction of the vibration unit.

However, when connecting two generators of the same type as shown in Figure 8a, the poles of the magnets are close to each other in the connection portion between the generators and the repulsive force acts, which is a factor that reduces the connection between the generators.

When connecting the generator facing the S pole and the generator facing the N pole as shown in FIG. 8B, different polarities of the magnets are closer to each other in the connection portion between the generators, which causes the attraction between the generators. .

After all, when alternatingly connecting the generator facing the S pole and the generator facing the N pole, it can be seen that the generation efficiency is high and the connectivity of the generator is high.
