Description

Generator {GENERATOR}

The present invention relates to a generator, and more particularly, to a generator capable of generating a high kinetic energy with a small kinetic energy by using a simple structure such that pendulum motions or rotational motions are easily generated and maintained for a long time.

BACKGROUND ART [0002] Conventionally, a number of generators for generating electricity using pendulum motions have been disclosed.

For example, in the " portable mobile phone charging device ", the driving force generated by the sector wheel, which is a sector type wheel, reciprocates right and left by the pendulum principle, A portable handset charging device is disclosed. In addition, in JP-A-10-2006-0008665 (published on Mar. 21, 2006), a compact generator using a weight center weight and a light emitter having the weight are provided with an eccentric member and a weight center weight, Or rotating force due to rotation inertia. In addition, "Generation Device Using Vacuum State and Magnet Pendulum Motion" disclosed in Japanese Patent Application Laid-Open No. 10-2013-0038777 (published on Mar. 18, 2018) introduces a power generation device using a pendulum motion of a magnet, So that the generated power can be generated.

Such conventional power generation apparatuses are configured to pendulum or rotate about a shaft eccentrically mounted on the weight body, and the inclination of the shaft on which the weight body is installed is changed by moving the apparatus or by moving the object on which the apparatus is installed, The body develops by using the pendulum movement due to the movement which is displaced by the influence of gravity. Further, in these conventional power generation apparatuses, a generator unit is disposed on a shaft on which a weight body is installed, and power is generated by being derived from the driving force of such a shaft.

However, the pendulum motion generator of the prior art uses a pendulum motion which is caused by a motion in which a weight disposed at an eccentric position is displaced by the influence of gravity, so that an efficient pendulum motion of the weight can not be expected, A decrease in rotational force due to wear, friction resistance, and clearance due to rotation may adversely affect the pendulum motion.

In order to solve these problems, the present applicant's patent application No. 10-2015-49392 (filed on April 8, 2015), which is a pending application, discloses that a plurality of movable permanent magnets are arranged around a circular fixed permanent magnet The movable permanent magnet is disposed at the eccentric position so that the movable permanent magnet interacts with the stator coil disposed on the motion path while moving by the pendulum movement or the rotary motion, thereby generating power efficiently.

In this technique, the movable permanent magnet is coupled around the circular fixed permanent magnet by the magnetic force, so that the pendulum movement or the rotation movement is smoothly generated without the need of the rotary shaft.

However, the rotation of the movable permanent magnet is not made around the rotation axis, but is rotated by the rotational motion in a state where it is coupled by the magnetic force around the fixed permanent magnet, so that the resistance of the magnetic force may lower the efficiency of the rotary motion. In addition, there is a structural drawback in that the rotation of the movable permanent magnet is not assisted by the magnetism of the magnetization of the stator coil disposed on the motion path of the movable permanent magnet.

The present invention has been made in view of the foregoing points in the prior art, and it is an object of the present invention to provide a generator capable of generating a high efficiency with a small kinetic energy by using a simple structure, .

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a generator comprising: a fixed disk having at least one stator coil arranged therein; And a rotary disk in which one or more permanent magnets are arranged and spaced apart from the fixed disk above the fixed disk and whose rotation axis is disposed coaxially on the central axis of the fixed disk to pendulum or rotate on the fixed disk Wherein the at least one permanent magnet is arranged at a position where the rotary disk is eccentric so that a load of the at least one permanent magnet is applied to the eccentric position so as to induce or sustain the pendulum movement or the rotary motion, The at least one permanent magnet may act on the at least one stator coil to generate an induced current according to pendulum motion or rotational motion.

At this time, the one or more permanent magnets may be plural and the polarities may be alternated.

In addition, the at least one stator coil may be a plurality of stator coils and may be disposed apart from each other.

The plurality of permanent magnets may be arranged in the form of an arc.

The plurality of permanent magnets may be disposed adjacent to each other or may be spaced apart from each other.

The one or more stator coils may be plural, and the stator coils generating in-phase induction current may be connected in series to collect the induced current.

Further, the fixed disk and the rotating disk may be housed in an outer casing having a bearing portion, and the rotating shaft may be formed in the bearing portion.

Further, the induced current can be collected and rectified to DC.

The number of the stator coils may be equal to the number of the permanent magnets, or may be two times the number of the permanent magnets.

In addition, the pendulum motion or the rotation motion of the rotating disk may be performed by receiving at least one of waves, vibration of the water surface, and vibration energy of the human body.

The pendulum motion generator according to an embodiment of the present invention includes a fixed disk 12 and a rotating disk 14, which are generally housed in an outer casing 10 as shown in FIGS.

The rotary disk 14 is installed in a bearing portion 18 formed in the outer casing 10 so that the rotary shaft 16 can be disposed on the center axis of the fixed disk 12.

On the other hand, several stator coils 20A to 20D are arranged on the fixed disk 12 in an equally spaced circular array, and the rotating disk 14 is disposed close to the stator coils 20A to 20D, And is rotated above the stationary disk 12. The stationary disk 12 is rotated by the rotation of the stationary disk 12,

A number of circular permanent magnets (22A to 22D) are arranged in the form of an arc at the eccentric position of the rotary disk (14). These permanent magnets can be any known permanent magnets, including commonly used alnico magnetites, sintered ferrite magnetics, or rare earth magnetites such as nidium (Nd). Since the permanent magnets 22A to 22D have a relatively heavy weight at the eccentric position of the rotary disk 14 disposed thereon, the permanent magnets 22A to 22D can be rotated by rotating the rotary disk 14 ) To continue the rotational force of the motor. The rotating disk 14 having the permanent magnets 22A to 22D arranged therein will function as a flywheel at the time of rotation.

In FIGS. 1 and 2, the permanent magnets 22A to 22D are circular, four, and spaced apart from each other, but the present invention is not limited thereto. That is, in the present invention, the permanent magnets 22A to 22D may have any shape other than a circular shape. The number of the permanent magnets 22A to 22D that can be all disposed at the eccentric position of the rotary disk 14 may be one or more and the permanent magnets 22A to 22D may be adjacent to each other .

The pendulum motion generator according to the present invention is configured such that the permanent magnets 22A to 22D of the rotating disk 14 rotate while interacting with the stator coils 20A to 20D of the fixed disk 12 to rotate the stator coils 20A to 20D Thereby generating electricity by inducing a current.

The operation of this embodiment will be described in detail with reference to Figs. 3A to 3B and 4A to 4B. 3A and 3B and FIGS. 4A and 4B are a schematic cross-sectional view and a plan view, respectively, for sequentially describing the power generation operation of the pendulum motion generator according to this embodiment, wherein FIGS. 3A and 4A are perspective views of permanent magnets 22A And FIG. 4B is a schematic cross-sectional view and plan view illustrating that induction currents are generated in the corresponding stator coils 20A to 20D when the permanent magnets are rotated from the first position Sectional view illustrating that an induction current is generated in a corresponding stator coil when the rotor is rotated a predetermined distance and is in the second position.

As shown in Figs. 3A to 3B, each of the permanent magnets in this embodiment is connected in two phases by arranging the poles alternately to each other. In FIGS. 1 and 2, two pairs of permanent magnets are shown as a pair of the upper and lower permanent magnets. In an embodiment, however, one permanent magnet may be disposed on the upper side or the lower side only.

3A and 4A, when the first permanent magnet 22A of the rotating disk 14 enters the region of the first stator coil 20B, the first stator coil 20B is rotated by the Lenz's law An induced current I is generated in a direction in which the N pole is induced at the upper end and the change of the magnetic flux is disturbed. Likewise, since the third permanent magnet 22C having the same polarity as the first permanent magnet 22A also enters the third stator coil 20C region, the N pole is induced at the upper end thereof and the induced current (I) occurs.

When the first permanent magnet 22A of the rotating disk 14 further moves out of the region of the first stator coil 20B as shown in FIGS. 3B and 4B, the first stator coil 20B is rotated by the Lentz law An S pole is induced at the upper end thereof, and an induced current I is generated in a direction that interferes with the change of the magnetic flux. Likewise, since the third permanent magnet 22C having the same polarity as the first permanent magnet 22A also goes out of the third stator coil 20C region, the S pole is induced at the upper end thereof, and the induced current (I) occurs.

Although only the first and third permanent magnets 22B and 22C and the first and third stator coils 20B and 20C have been described above as examples for convenience of explanation, all of the permanent magnets 22A to 22D are connected to the stator coils 20A to 20D, 20D to generate the induced current I as above would be quite natural for a person skilled in the art.

Therefore, by connecting the stator coils 20A to 20D in series, it is possible to collect the generated electric current by flowing the induced current instantaneously generated as described above. It is a matter of course that an AC current can be converted into a DC by connecting a well-known rectifier circuit to the terminal portion of such a series circuit.

FIGS. 5 to 8B illustrate another embodiment of the present invention for further increasing the power generation efficiency by further shortening the interval of the stator coils in the above-described embodiment as shown in FIGS. 1 to 4B.

That is, the present embodiment is identical in construction to the above-described embodiment, except that the number of stator coils 120A to 120H is reduced by the number of mutually spaced coils. Since the number of the stator coils generating the induction current is increased in this way, the number of power generation increases and the efficiency of collecting the induction current is improved.

The manner of operation of this embodiment will be described in detail with reference to Figs. 7A to 7B and Figs. 8A to 8B. FIGS. 7A and 7B and FIGS. 8A and 8B are a schematic sectional view and a plan view, respectively, for sequentially describing the power generation operation of the pendulum motion generator according to the present embodiment. FIGS. 7A and 8A are views showing permanent magnets 122A And FIGS. 7B and 8B are schematic cross-sectional views and plan views illustrating that induction currents are generated in the corresponding stator coils 120A to 120H when the rotor is in the first position Sectional view illustrating that an induction current is generated in a corresponding stator coil when the rotor is rotated a predetermined distance and is in the second position. It is described briefly in the manner of operation of the previous embodiment.

First, when the permanent magnets 122A to 122D of the rotating disk 14 enter the respective regions of the stator coils 120C to 120F as shown in FIG. 7A, the stator coils 120C to 120F are subjected to the magnetic flux The induced current I is generated in a direction that interferes with the change of the induction current I. However, the induced currents generated in the stator coils 120C and 120E and the induced currents generated in the stator coils 120D and 120F are opposite to each other due to the permanent magnets 122A to 122D arranged with alternating polarities.

At the same time, in the case of the stator coil 120D, an induced current I is generated due to the permanent magnet 122A exiting the region and the permanent magnet 122B entering the region thereof, and the permanent magnet 122A and permanent Since the polarities of the magnets 122B are different from each other, the direction of the induced current I generated is the same and does not conflict with zero. This is also true for the remaining stator coils 120E and 120F without inducing the induction current I due to the permanent magnets 122B and 122C going out of these regions. Further, in the case of the stator coil 120G, an induced current I is generated due to the permanent magnet 122D exiting the region.

7B and 8B, when the permanent magnets 122A to 122D of the rotating disk 14 move out of the respective regions of the stator coils 120C to 120F (and the permanent magnets 122A are arranged on the stator coils 120B ), The induced current I is generated in the same manner as described above to generate power.

Therefore, in this embodiment, since an induction current is generated in two phases as described above, a set of stator coils (for example, 120C, 120E, and 120G) 120D, 120F, etc.) can be connected in series and output separately.

The above-described pendulum motion generator according to the present invention can be used as follows.

First, the pendulum motion generator of the present invention may be installed in a floating body (not shown) so that the pendulum motion generator of the present invention can be manufactured in a large size and float in the sea, for example, and can be used as a power plant facility. In this case, in the pendulum motion generator according to the present invention, the rotating shafts 16 and 116 of the rotating disks 14 and 114 are placed at an oblique position instead of the vertical position in the process of floating, and the permanent magnets 22A to 22D and 122A to 122D The rotary discs 14 and 114 start to rotate in one direction or the other, and the inertial action at the time of rotation causes the rotary disc to repeatedly perform pendulum movement or continuous rotation movement, The magnet can generate electricity by interacting with the stator coils 20A to 20D and 120A to 120H of the fixed disks 12 and 112 in its motion path.

Secondly, in a case where the pendulum motion generator of the present invention is manufactured in a compact size that can be carried and used in a power generating device capable of supplying a charging power source for a user's portable electronic device such as a cellular phone, (Not shown) such as a housing and a belt suitable for the wrist or the ankle as a relatively large part of the user's body in the user's body. For example, when the pendulum motion generator according to the present invention is miniaturized and worn on the wrist or ankle, the fixed disks 12 and 112 and the rotating disks 14 and 114 are arranged such that the center axis of the fixed disks 12 and 112, Or the body part of the ankle makes a pendulum movement in which the permanent magnets 22A to 22D and 122A to 122D reciprocate forward and backward according to the user's movement, . Electricity can be generated in the stator coil by inducing a current in the stator coil due to interaction with the stator coils 20A to 20D and 120A to 120H, which are encountered on the motion path by the pendulum motions or the rotational motions of the permanent magnets. Thus, the power generated by the pendulum motion generator can be used for charging the user's portable electronic device.

As described above, according to the present invention, a plurality of circular permanent magnets are eccentrically and concentrically arranged on a rotating disk having a stator coil arranged in an equally spaced circular array on a fixed disk and coaxially rotatably arranged with the fixed disk, The eccentrically disposed rotating disk can be rotated by the pendulum motion or further rotational motion under the influence of the biased permanent magnet so that power generation can be achieved through mutual cooperation between the permanent magnet of the rotating disk and the stator coil of the fixed disk And to provide a pendulum motion generator.

It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims, , Changes, additions, and the like are to be regarded as falling within the scope of the claims. As an example, unlike the one shown in this specification, the permanent magnet and the stator coil may be respectively one, or one of the permanent magnets or the stator coil may be one, and the other may be plural.
