Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a driving device according to a preferred embodiment of the present invention.

As shown in FIG. 1, the driving apparatus of the present invention includes an electromagnet actuator 100, a power generator 200, a storage battery 300, and a power supply system (not shown).

The electromagnet actuator 100 linearly moves the movable member 160 integrated with the coil 170 by the magnetic field caused by the permanent magnets 130 and 132 and the electromagnetic repulsive force due to the current density of the coil 170 by the left-hand law of Fleming. The driven system 400 is driven by a linear reciprocating motion of the mover 160 integrated with the coil 170.

The power generation system 200 includes a coil circuit 210 disposed on one side of the electromagnet actuator 100 and includes a permanent magnet 220 installed at one end of the mover 160. Therefore, the permanent magnet 220 linearly reciprocates the inside of the coil circuit 210 by the linear reciprocating motion of the mover 160 to induce electromotive force to the coil circuit 210.

The power generated by the power generator 200 is stored in the storage battery 300. In the example shown in the drawings, the power generated by the power generator 200 is stored in the storage battery 300 through the capacitor 310. The storage battery 300 can be recharged separately from the outside, and since the power generated by the power generator 200 is stored, the application time of the storage battery 300, that is, the effective discharge time can be extended.

The power supply system is for supplying current to the coil 170 of the electromagnet actuator 100 and may be provided separately from the storage battery 300, as shown in FIG. 1, the storage battery 300. It is preferable to use the power of. In this case, the storage battery 300 serves as a power supply system for supplying current to the coil 170 of the electromagnet actuator 100.

In addition, as illustrated in FIG. 1, a current control system 500 capable of changing a flow direction of a current supplied from the storage battery 300 to the coil 170 of the electromagnet actuator 100 may be provided. In this case, the current control system 500 is opposite to each other when the direction of the current applied to the coil 170 is at the top and when the mover 160 of the electromagnet actuator 100 is at the bottom of the drawing. It is possible to operate (reciprocating movement) the mover 160 in both directions by controlling to flow to.

Alternatively, the current flowing through the coil 170 may always flow in only one direction. In this case, a force for moving the mover 160 in only one direction is generated. To move the mover 160 to the opposite side requires a separate means.

The driven system 400 is to be driven through the driving device according to the present invention, and is driven by receiving the linear reciprocating motion of the mover 160 as it is or rotating the linear reciprocating motion of the mover 160. It can be converted to other motions and driven.

An example of a driven system 400 having a very simple structure is schematically illustrated in FIG. 1. The illustrated driven system 400 is configured by the linear reciprocating motion of the mover 160. The piston 410 is a compression cylinder that moves in the cylinder 420 to compress air.

Here, an elastic means 430 for providing a biasing force to the piston 410 is added to the compression cylinder which is the driven system 400. This means that the current flowing through the coil 170 always flows in only one direction, so that when the operating force is provided only in the direction of compressing air to the mover 160, the elastic means 430 after compressing air. This illustrates that the mover 160 is returned to its original position. Therefore, when a current flows in the coil 170, the piston 410 of the mover 160 moves downward while compressing the elastic means 430 to compress and discharge air, and if the current is blocked again, the elastic means ( The piston 410 and the mover 160 are raised and restored by the restoring force of 430.

If, as described above, the current control system 500 that can change the flow direction of the current supplied from the battery 300 to the coil 170 of the electromagnet actuator 100 is provided, the mover ( When the piston 410 of the 160 compresses the air, and then reverses the direction of the current flowing in the coil 170, a force for moving the mover 160 in the opposite direction acts, thereby moving the mover 160. There may be no means such as the elastic means 430 for restoring.

2A and 2B show the electromagnet actuator part of FIG. 1 in detail, FIG. 2A is an enlarged sectional view of a main part, and FIG. 2B is a sectional view A-A of FIG. 2A.

As shown in FIGS. 2A and 2B, the electromagnet actuator 100 includes an inner cylinder 110 and an outer cylinder 120 that are made of magnetic material and are arranged concentrically while maintaining a predetermined interval in the radial direction.

The permanent magnet is composed of an inner permanent magnet 130 and an outer permanent magnet 132, the inner permanent magnet 130 is installed in contact with the outer surface of the inner cylinder 110, the outer permanent magnet 132 is the Installed in contact with the inner surface of the outer cylinder 120 is arranged to maintain a predetermined distance from each other.

Both ends of the inner cylinder 110 and the outer cylinder 120 are blocked by the first and second end plates 140 and 150. The first and second end plates 140 and 150 are coupled to the inner cylinder 110 and the outer cylinder 120 by welding or the like. The first and second end plates 140 and 150 may be made of a magnetic material to induce a magnetic field to flow smoothly between the inner cylinder 110 and the outer cylinder 120.

The movable member 160 includes a movable ring 162, a connecting shaft 164, a connecting plate 166, and a moving shaft 168.

The movable ring 162 is made of a nonmagnetic material, and is installed to allow linear movement in the axial direction between the inner permanent magnet 130 and the outer permanent magnet 132.

The connecting shaft 164 extends from the movable ring 162 and passes through the first end plate 140.

The connecting plate 166 connects end portions of the connecting shafts 164.

The moving shaft 168 extends from the center of the connecting plate 166, and is installed in the inner cylinder 110 to enable linear movement. Accordingly, the moving shaft 168 moves linearly in the axial direction by the movement of the movable ring 162 to operate the driven system 400 substantially.

In addition, the connection plate 166 is provided with a permanent magnet 220 of the power generation system 200.

The coil 170 is installed at one end of the movable ring 162.

In the driving device of the present invention as described above, when a current is applied to the coil 170 of the electromagnet actuator 100 through the current control system 500, the magnetic field by the permanent magnets 130 and 132 and the electric field of the coil 170 are applied. As a result of the force acting to move in the axial direction to the coil 170, the coil 170 is moved along the movable ring 162 in the axial direction.

For example, in FIG. 2A, when the coil 170 and the mover 160 to which it is integrated are lowered, current is flowed to the coil 170 in the direction shown in the left figure of FIG. 2A. The coil 170 receives a force in a rising direction such that the coil 170 and the mover 160 are lifted in the axial direction. In addition, as shown in the right view of FIG. 2A, when a current is flowed to the coil 170 in a direction opposite to the above-described direction, the coil 170 receives a force in a downward direction to move the coil 170 and the movable portion. The ruler 160 is lowered again in the axial direction.

As the mover 160 reciprocates in the axial direction as described above, the driven system 400 connected to the moving shaft 168 of the mover 160 is operated, while the connecting plate 166 of the mover 160 is operated. Since the permanent magnet 220 installed in the reciprocating inside the coil circuit 210, a large electromotive force is induced in the coil circuit 210.

The electromotive force induced in the coil circuit 210 is charged to the storage battery 300 via the capacitor 310, the power of the storage battery 300 is supplied to the coil 170 of the electromagnet actuator 100.

As described above, in the driving device of the present invention, the driven system 400 is operated by the movement of the mover 160 by the coil 170 of the electromagnet actuator 100, and the electric power is generated through the power generation system 200. Since it is possible to produce and accumulate it, energy efficiency is improved and the use time of the storage battery 300 can be significantly extended. Accordingly, the recharging interval of the storage battery 300 is widened, so that the storage battery 300 does not need to be frequently recharged.

FIG. 3 shows an example in which the driving device of the present invention is applied to an engine as a vehicle or a ship. That is, it shows the case where the vehicle or the ship is the driven system 400 mentioned above.

In the example shown in FIG. 3, three or more electromagnet actuators 100 and a power generator 200 are installed in parallel. As such, the movers 160 of the electromagnet actuators 100 installed in parallel are connected to the crank mechanism 600, whereby the linear reciprocating motion of the movers 160 is rotated by the crank mechanism 600. It is converted to transmit rotational power to the driven system.

In the example shown in FIG. 3, the crank mechanism 600 specifically includes a crank shaft 610 and a connecting rod connecting the crank shaft 610 and the moving shaft 168 of the mover 160. 620.

The crankshaft 610 is driven to rotate or directly drive the flywheel 630 that is power-connected to the wheel of the car or the screw of the ship.

Thus, when connecting three or more drive devices with the crank mechanism 600, only the one-way actuation force may be provided to the said mover 160. FIG. That is, in FIG. 3, the force may be applied only in the direction in which the mover 160 is raised (the direction in which the connecting rod 620 is pulled upward), or the direction in which the mover 160 is lowered (the connecting rod 620). The force may be applied only in the direction of pushing downward. For example, when the current is sequentially applied to the coil 170, such as a method of sequentially applying the current in response to the explosion stroke of the cylinder in a general engine, the mover 160 of each electromagnet actuator 100 is crankshaft. Forces are sequentially applied to 610. The point of time when the current is applied to the coil 170 is applied when the mover 160 is at the top dead center or the bottom dead center of the stroke, and the arrangement angle of the crankshaft (eg, three 120 degree angles and four 180 degree angles). , Four 90-degree angles, etc.) may be applied to one coil 170 at a time, or two or more coils 170 at a time.

In FIG. 3, a distributor 510 serves to sequentially apply current to each of the coils 170 from the storage battery 300. For example, the current may be simultaneously applied to the coils 170 of the first and fourth electromagnet actuators 100, and the current may be applied to the coils 170 of the second and third electromagnet actuators 100 again. Otherwise, the present invention may be applied in various ways, such as applying a current to the coil 170 of one electromagnet actuator 100 at a time in the order of first to third to fourth to second. have.

In addition, as shown in FIG. 3, the present invention may further include a generator 640 at one end of the crank shaft 610 of the crank mechanism 600.

Power generated by the generator 640 is charged to the storage battery 300 through the capacitor 310.

Compared to the driving force of the driven system 400 such as a vehicle by the electromagnet actuator 100, the force required to move the permanent magnet 220 of the power generation system 200 and the driving force of the generator 640 are required. Power is very insignificant. As described above, the present invention can maximize energy efficiency because it has a structure capable of producing large power with very little force.

On the other hand, the conventional electric vehicle has a principle of driving the motor using the power of the battery, and rotating the wheel by the rotation of the motor.

The motor forms a magnetic field by applying current to the coil, and has a principle of rotating the rotor by a force of half polarity between the rotor and the stator with the polarity of the magnetic field.

For example, in order to drive a driven system such as a vehicle, a rotational motion must be derived. The motor has an advantage of directly inducing a rotational motion of the rotor.

On the other hand, the motor not only has to be made of a magnetic material so that the stator and the rotor can flow magnetic fields, but when the magnetic materials are magnetized to some extent, the magnetization reaches a 'magnetic saturation state' in which the magnetization does not proceed even if the current is increased. In saturation, even if the current is continuously increased, a force beyond a certain limit cannot be obtained. Therefore, the conventional electric vehicle is much lower in traction and climbing capacity than the internal combustion engine using gasoline or diesel fuel, but also has a low speed.

As mentioned above, in order to obtain a higher force and a higher speed, the saturation problem of the magnetic material has to be solved. In order to do so, the size of the magnetic material has to be increased, so the motor size has to be much larger than that of a vehicle or a ship, and the weight is much higher. It becomes heavy. In other words, in terms of optimization, the existing motor is limited in power and speed.

(J: 전류 밀도, B: 자속 밀도)를 얻는 원리를 가진다. However, the electromagnet actuator 100 according to the present invention flows a current in a direction perpendicular to the space in which the magnetic field is formed, that is, the force,

(J: current density, B: magnetic flux density).

That is, since the electromagnet actuator 100 of the present invention uses the force generated in the electric field and the magnetic field, the magnetic field due to the permanent magnet causes the saturation problem of the magnetic body as described above, but the electromagnet actuator 100 of the present invention. Since the amount of current flowing through the coil 170 is a system that is directly converted to a force, if a large amount of current flows to the coil 170, it is possible to obtain a large force.

Therefore, in the electromagnet actuator 100 of the present invention, it is not necessary to think about the saturation problem of the magnetic body in the place where the electromagnetic force is applied, and only by winding the number of turns of the coil 170 a lot, and increasing the intensity of the current, a greater force can be obtained. As a result, its size and weight can be greatly reduced.

Yet, according to the present invention, the permanent magnet 220 reciprocates in the coil circuit 210 to produce electric power according to the operation of the electromagnet actuator 100, and consists of a system for charging the generated electric power to the battery.

Therefore, when the present invention is applied to a vehicle, a ship, or the like, there is no problem of harmful gas emission compared to an engine by conventional fossil fuel, and it is possible to overcome the limitations of force, speed, weight, and the like compared to the conventional electric vehicle. In addition, it is possible to maximize the use time of the battery, it is possible to significantly improve the mileage compared to the conventional electric vehicle, it is possible to provide a drive device with little noise.

Such a driving device of the present invention can be easily applied not only to a vehicle but also to a part that needs to be continuously powered for a predetermined time by using electricity such as a motorcycle, a ship, and the like, and the efficiency thereof is very large.

In the foregoing description, specific embodiments of the present invention shown in the accompanying drawings have been described in detail, but this is only an example and the protection scope of the present invention is not limited thereto. In addition, the embodiments of the present invention as described above can be variously modified and equivalent other embodiments by those of ordinary skill in the art within the technical spirit of the present invention, such modifications and equivalent other embodiments are It goes without saying that it belongs to the appended claims of the invention.
In addition, the electromagnet actuator in the present specification has been described with reference to the form shown in the drawings, but is not necessarily limited to the form shown in the drawings, the magnetic field by the permanent magnet and the electromagnetic repulsive force by the current density of the coil It is sufficient to linearly reciprocate the mover integrated with the coil.

As described above, the drive device according to the present invention, by supplying electricity to the electromagnet actuator to drive the mechanical drive with improved force and speed, by producing and charging a separate power by its mechanical drive operation, Maximize the use time of the battery, there is no pollution and has the advantage of quiet operation.
