  Further, the vibration generator shown in Patent Document 2 is configured so that the so-called same-pole opposed magnets, in which the same poles of a plurality of magnets face each other and are integrated, are alternately reversed in the winding direction. Moreover, it becomes possible to generate electric power more efficiently by moving in the plurality of coils.

  The manual power storage battery shown in Patent Document 1 and the vibration generator shown in Patent Document 2 both generate electric power in the coil by the reciprocating movement of the permanent magnet in the case where the coil is formed on the outer periphery thereof. The electromotive force is inversely proportional to the square of the distance between the coil and the permanent magnet surface.

  As the permanent magnet, metals such as neodymium and iron are mainly used. Since these substances are rusted and deteriorated when they come into contact with moisture, the case of a manual storage battery or a vibration generator as described above needs to be sealed.

  Moreover, although the electromotive force is higher when the distance between the permanent magnet surface and the coil is shorter, if this distance is reduced, the risk of breakage due to intrusion of dust or the like from the outside increases, so that the case needs to be sealed again.

<First Embodiment>
Hereinafter, an electromagnetic induction power generating device of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional front view of an electromagnetic induction power generating device 1 according to a first embodiment. 2 is a cross-sectional view in the direction of the arrows along the line AA ′ of the electromagnetic induction power generating device of the first embodiment shown in FIG. 1. In the following description, the upper side of the drawing is defined as the upper side, and the opposite direction is defined as the lower side.

  As shown in FIGS. 1 and 2, the electromagnetic induction power generation device 1 is capable of freely moving in the longitudinal direction within the tubular member 2, the coil 3 wound around the outer surface of the tubular member 2, and the tubular member 2. It is comprised from the provided movable member 9 comprised with a permanent magnet.

  The tubular member 2 has a cylindrical shape and is made of an acrylic resin. A space 2a is provided inside the tubular member 2 with its longitudinal end portion opened. Movement restricting portions 12 b and 12 c are attached to the tubular member 2 at open ends 2 b and 2 c in the longitudinal direction of the tubular member 2. The movement restricting portions 12b and 12c are provided so as to block the open end portions 2b and 2c so that the movable member 9 does not come out of the space 2a. In the example of FIGS. 1 and 2, flat members are provided as the movement restricting portions 12b and 12c, and the space 2a is completely sealed. The movement restricting portions 12b and 12c are made of acrylic resin.

  In addition, in this embodiment, although the tubular member 2 was illustrated by the cylindrical shape, it is not limited to this shape, For example, other polygonal cylinder shapes, such as an elliptic cylinder shape and a square cylinder, may be sufficient. Moreover, the material which comprises the tubular member 2 should just be non-magnetic materials other than an acrylic resin, and may be metals, such as copper, aluminum, and brass.

  Buffer bodies 17b and 17c having a substantially columnar shape are provided on the inner surfaces of the movement restricting portions 12b and 12c by being bonded to the tubular member 2 and the movement restricting portions 12b and 12c. The buffer bodies 17b and 17c are made of an elastic material, and examples of the material include isoprene rubber, nitrile rubber, and butadiene rubber.

  The coil 3 is wound and fixed on the outer peripheral surface of the tubular member 2 in a direction orthogonal to the longitudinal direction of the tubular member 2. Both ends of the coil 3 are connected to the external wiring 20. As a material of the coil 3, copper was used. In the present embodiment, the coil 3 is provided by being wound around a part of the outer surface of the tubular member 2, but the coil 3 may be provided over the entire circumference of the tubular member 2.

  The movable member 9 is a permanent magnet having a cylindrical shape. The direction of magnetization of the permanent magnet constituting the movable member 9 is the same as the direction of movement. The movable member 9 is formed to have substantially the same size in the cross-sectional direction with respect to the space 2a in the tubular member 2, and moves freely only in the longitudinal direction of the space 2a.

  In addition, although the shape of the movable member 9 was illustrated by the cylinder, it is not limited to this shape. However, it is desirable to have the same cross-sectional shape as the space 2 a inside the tubular member 2.

  A through hole 15 extending in the moving direction is provided on a line connecting the centers of the left and right side surfaces of the movable member 9. The through hole 15 has a circular cross-sectional shape. In the present embodiment, only one through hole 15 is provided, but the number is not limited, and a plurality of through holes 15 may be provided.

  Next, operation | movement of the electromagnetic induction type generator 1 of this embodiment is demonstrated. First, the electromagnetic induction power generating device 1 of the present embodiment is vibrated in the longitudinal direction of the tubular member 2. The force applied to the electromagnetic induction power generation device 1 due to the vibration is transmitted as kinetic energy of the movable member 9. The movable member 9 reciprocates in the longitudinal direction in the space 2a at a speed given by the total force obtained from the applied force and the frictional force between the tubular member 2 and the resistance force from the gas. Go in and out of the space covered with snow. When passing through the space in the coil 3, the magnetic flux lines generated by the movable member 9 are orthogonal to the coil 3, and an induced current is generated at that time. When the movable member 9 repeats entering and exiting the space in the coil 3, an alternating current can be generated.

  In the electromagnetic induction power generating device 1 of the present embodiment, since the movable member 9 includes the through hole 15, when the power generation process as described above is performed, the through hole 15 becomes a vent hole, and air resistance due to movement is reduced. Since it can be reduced, high kinetic energy can be obtained. This is particularly effective when the movable member 9 is in a closed space such as the tubular member 2 as in this embodiment. Further, since the through hole 15 functions as a vent hole, it is not necessary to make a space between the surface of the permanent magnet constituting the movable member 9 and the tubular member 2, so that the inner surface of the tubular member 2 can be brought closer. Efficient power generation can be performed. In addition, since the elastic buffer bodies 17b and 17c are provided at both ends of the tubular member 2, damage due to contact between the movable member 9 and the movement restricting portions 12b and 12c can be prevented.

  In addition, the electromagnetic induction type power generating device of the present embodiment is similar to the electromagnetic induction type power generating device 50 shown in FIG. 21 can be attached. In this case, the wiring 20 connected to the coil 3 is connected to the storage battery 21 through a charging circuit (not shown) through a hole provided in the movement restriction unit 12c (not shown), and is provided from the storage battery 21 to the movement restriction unit 12c (not shown). Electric power is supplied to the external wiring 22 through the formed hole. By adopting this configuration, it is possible to reduce the size of the apparatus using the power generation apparatus of this embodiment. In addition, the buffer body 17c attached to the movement restricting portion 12c to which the storage battery 21 is attached is a buffer body 57c having a shape in which a hole is provided in a part to which the storage battery 21 is attached, as shown in FIG. Also good. Moreover, it is also possible to provide other electronic components instead of the storage battery 21. Moreover, you may attach the said electronic component not only to the inner surface of the movement control part 12c but to the inner surface of the movement control part 12b.

Second Embodiment
Next, an electromagnetic induction power generating device according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 4 is a longitudinal sectional view of the electromagnetic induction power generating device of the second embodiment. FIG. 5 is a cross-sectional view in the direction of the arrows along the line BB ′ of the electromagnetic induction power generating device of the second embodiment shown in FIG.

  As shown in FIGS. 4 to 5, the electromagnetic induction power generating apparatus 100 of the second embodiment is freely movable in the longitudinal direction in the tubular member 2, the coil 3 wound around the outer surface of the tubular member 2, and the tubular member 2. A movable member 109 having a plurality of through holes extending in the moving direction, and a guide member 105 inserted into one of the plurality of through holes. Has been. Compared with the electromagnetic induction power generation device 1 of the first embodiment, the difference is that there are a plurality of through holes and the guide member 105 is provided. The following description will be made only on points that are different from the first embodiment, and the same points as those in the first embodiment will be denoted by the same reference numerals and description thereof will be omitted.

  The movable member 109 has the same material and shape as the movable member 9 of the first embodiment, and is provided in the space 2 a in the tubular member 2. Three through holes 115a, 115b, and 115c extending in the moving direction are provided on a line connecting the centers of the left and right side surfaces of the movable member 109. The through hole 115 has a circular cross-sectional shape. In the present embodiment, three through holes are provided. However, the number is not limited, and a plurality of through holes may be used.

  The guide member 105 has a cylindrical shape formed of aluminum, and the movable member 109 is movably inserted into a through hole 115 a provided in the movable member 109. Both ends of the guide member 105 are fixed to the center points of the movement restricting portions 12b and 12c. The material of the guide member 105 is not limited to aluminum, and may be a metal such as copper or brass or a resin such as an acrylic resin as long as it is a non-magnetic material. The shape of the guide member 105 is not limited to a cylindrical shape, and may be an elliptical column shape or a polygonal column shape, but the cross-sectional shape may be substantially the same as the through-hole 115a that is inserted. desirable.

  When a plurality of through holes 115 are provided in the movable member 109, the guide member 105 only needs to be inserted into one of them, and the plurality of guide members are respectively inserted into the plurality of through holes. Although it is good also as a structure, there must be at least one through-hole through which the guide member is not inserted. Moreover, although the sizes of the through hole 115a and the through holes 115b and 115c are different, they may be the same.

  Buffers 117b and 117c having a substantially cylindrical shape and having a hole at the center thereof are bonded to the movement restricting portions 12b and 12c on the inner surfaces of the movement restricting portions 12b and 12c, and the guide member 105 is inserted into the holes. Is provided. The buffer bodies 117b and 117c are formed of an elastic material, and examples of the material include isobrene rubber, nitrile rubber, and butadiene rubber.

  The operation of the electromagnetic induction power generating device 100 of this example is the same as that of the first embodiment. However, since the three through holes 115 are provided and the guide member 105 is inserted into the through hole 115a, the movable member reciprocates along the guide member, so that the movable member stably reciprocates within the tubular member. Since it becomes possible to move and damage to the movable member is less likely to occur, stable power generation can be performed over a long period of time. Moreover, since the through-holes 115b and 115c through which the guide member is not inserted serve as vent holes, the resistance of the air due to movement can be reduced, so that high kinetic energy is obtained.

<Third Embodiment>
Next, an electromagnetic induction power generating device according to a third embodiment of the present invention will be described with reference to the drawings. FIG. 6 is a longitudinal sectional view of the electromagnetic induction power generating device according to the third embodiment. FIG. 7 is a cross-sectional view in the direction of the arrows along the line CC ′ of the electromagnetic induction power generating device of the third embodiment shown in FIG.

  As shown in FIGS. 6 to 7, the electromagnetic induction power generating device 200 according to the third embodiment is freely movable in the longitudinal direction in the tubular member 2, the coil 3 wound around the outer surface of the tubular member 2, and the tubular member 2. It is comprised from the movable member 209 which has the through-hole extended in the moving direction comprised with the permanent magnet provided in the inside. Compared to the electromagnetic induction power generation device 1 of the first embodiment, the configuration of the movable member 209 is different. The following description will be made only on points that are different from the first embodiment, and the same points as those in the first embodiment will be denoted by the same reference numerals and description thereof will be omitted.

  The movable member 209 is configured as a same-pole opposed magnet in which two permanent magnets 219a and 219b that have a cylindrical shape and are magnetized in the longitudinal direction are fixed so that the same poles face each other. The movable member 209 is formed in substantially the same size in the cross-sectional direction with respect to the space 2a in the tubular member 2, and moves freely only in the longitudinal direction of the space 2a.

  A through hole 215 extending in the moving direction is provided on a line connecting the centers of the left and right side surfaces of the movable member 209. The through hole 215 has a circular cross-sectional shape.

  A tubular member 202 is provided in the through hole 215 so as to be fixed to the inner surface of the through hole 215.

  The operation of the electromagnetic induction power generating device 200 of this example is the same as that of the first embodiment. However, since the movable member 209 is a homopolar facing magnet, the maximum value of the magnetic flux density across the coil is higher than when a normal permanent magnet is used as the movable member. For this reason, the Lorentz force applied to the free electrons constituting the coil is increased, and as a result, a large electromotive voltage can be obtained. In addition, since the movable member 209 which is a homopolar facing magnet is fixed to the tubular member 202 through the through-hole 215, the two permanent magnets 219a and 219b repel each other on the surface where the same polarity is opposed. Therefore, the possibility of breakage can be reduced, and stable power generation can be performed over a long period of time.

  The tubular member 202 corresponds to the second tubular member of the present invention.

<Fourth embodiment>
Next, an electromagnetic induction power generating device according to a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 8 is a longitudinal sectional view of the electromagnetic induction power generating device according to the fourth embodiment. FIG. 9 is a cross-sectional view in the direction of the arrows along the line DD ′ of the electromagnetic induction power generating device of the fourth embodiment shown in FIG.

  As shown in FIGS. 8 to 9, the electromagnetic induction power generating device 300 of the fourth embodiment is freely movable in the longitudinal direction in the tubular member 2, the coil 3 wound around the outer surface of the tubular member 2, and the tubular member 2. It is comprised from the movable member 309 which has two through-holes which are comprised by the permanent magnet and can be moved to the moving direction. Compared to the electromagnetic induction power generation device 1 of the first embodiment, the configuration of the movable member 309 is different. The following description will be made only on points that are different from the first embodiment, and the same points as those in the first embodiment will be denoted by the same reference numerals and description thereof will be omitted.

  The movable member 309 is configured as a same-pole counter magnet in which two permanent magnets 319a and 319b that are cylindrical and magnetized in the longitudinal direction are fixed so that the same poles face each other. The movable member 309 is formed to have substantially the same size in the cross-sectional direction with respect to the space 2a in the tubular member 2, and freely moves only in the longitudinal direction of the space 2a.

  In addition, two through holes 315a and 315b extending in the moving direction are provided on the axis connecting the left and right side surfaces of the movable member 309. The through holes 315a and 315b have a circular cross-sectional shape.

  The through-hole 315a and the through-hole 315b are provided with a wire member 325 wound through the two through-holes 315a and 315b after being inserted through the through-holes. The wire member 325 may be a non-magnetic material, and a resin thread is used in this embodiment.

  The operation of the electromagnetic induction power generating device 300 of this example is the same as that of the first embodiment. However, since the movable member 309 is the same-pole opposed magnet, the density of the generated magnetic flux becomes higher as compared with the case where a normal permanent magnet is used as the movable member, as in the third embodiment. The electromotive voltage generated when passing through the space is also increased, and power generation can be performed more efficiently. In addition, by providing the wire member 325 wound over the two through holes 315a and 315b, the two permanent magnets 319a and 319b are more firmly fixed, and the same pole faces each other. It is possible to reduce the possibility of breakage due to repulsion, and stable power generation can be performed over a long period of time.
