Description

Power generator

The present invention relates to a power generation apparatus in which a power generation magnet in a fixed part moves in a coil to generate power by movement of an attracting magnet in a moving part, and further, a light emitting diode is turned on by the electric energy .

At night, there are things that turn on and blink a side reflector, a rear reflector, or an LED (light emitting diode) in order to inform the side or rear of the bicycle of the presence of the bicycle and maintain safety.

  The reflection type cannot be confirmed unless it is illuminated with light from the side or rear. The thing which blinks LED by battery drive requires not only the replacement of the battery but also a control circuit for blinking the LED.

  There has been proposed a taillight with a built-in LED that makes a driving battery unnecessary by blinking with a generator attached to a bicycle.

One is a thing which drives both a headlight and a taillight using the generator for headlights.
In the case of using a headlight generator, power is directly supplied from the generator to the taillight and blinked only during traveling. The other form of the thing using the generator for headlamps is such that the taillight is turned on even when the bicycle is stopped (see Patent Document 1). Among them, separate the headlight and taillight, rectify the output from the generator and charge the condenser or secondary battery to light the taillight. We are using.

  Since the headlight generator is usually installed on the front wheel side, it must be wired from the front to the rear of the bicycle, so it can be wired by operating the handle or by an accident such as a wire being caught during use. Is not suitable for long-term use.

  Some have a tail lamp generator on the rear wheel side. Attach two power generation coils to the arch-shaped bracket, attach a magnet to the rim of the rear wheel via a clip bracket, and generate electricity when the magnet passes between the two coils by rotating the rear wheel. It is a thing to use (refer patent document 2).

If a generator dedicated to lighting is installed on the bicycle frame side and power is directly supplied from the generator to the light emitting diode to blink, the light emitting diode blinks at the generator generation cycle, so the control circuit for blinking is It becomes unnecessary and a cost reduction can be aimed at. However, as proposed in Patent Document 2, an object in which a magnet only passes between two coils has a structure in which the magnetic field between the magnet and the coil does not form a closed magnetic circuit or does not easily form a closed magnetic circuit. In order to take into account the vibration of the bicycle and the rotational vibration of the wheel, the distance between the magnet and the coil and the gap need to be opened by several millimeters, resulting in poor power generation efficiency.

  Therefore, the object of the present invention is to make the coil and the magnet as close as possible so that the magnet moves inside the coil. Even at low speeds, power is generated without imposing a load on rotation so that the number of lighting can be increased.

Preferred embodiments of a power generation method and a power generation apparatus according to the present invention described in claims 1 to 7 will be described below with reference to the drawings.

FIG. 1 shows a power generation method and a power generation apparatus according to the present invention, in which a suction magnet assembly 8 having a suction magnet 16 is fixed to two spokes 4 of a bicycle wheel 6 as a moving part, while the frame 3 is fixed. The two holding bands 19 having the holding band connection plate 22 are attached, and the power generation magnet assembly 10 having the power generation magnet 28 as a fixing portion is attached to one side of the holding band connection plate 22. the holding band 19 as comprising on the nearest track of rotation, Ru solid Teisu the generator magnet assembly 10 to the frame 3.

At this time, the opposing polarities of the attracting magnet 16 and the power generation magnet 28 are opposite to each other. When the polarity of the attracting magnet 16 is N pole, the polarity of the power generating magnet 28 is also N pole. The power generation magnet assembly 10 is fixed so that the distance between the magnet magnet assembly 10 and the attracting magnet 16 on the other side is the best.

FIG. 2A is a front view of the attracting magnet assembly 8 attached to the spoke 4, and FIG. 2B is a cross-sectional view of the AA portion.
As shown in FIG. 2B, the suction magnet assembly 8 includes a suction magnet holding plate 11, a suction magnet holding plate 14, a spacer 13, a holding tube 12, It is formed of a suction fitting 9 or the like, and a spacer 13 is inserted in the center with two spokes 4 interposed therebetween, and a flat head screw 15 is inserted into two holes and fixed with a nut 51 or the like.

The thickness of the spacer 13 is equal to or less than the thickness of the two spokes 4 and is firmly fixed with screws 15.
The suction fitting 9 is magnetized and adsorbed on the upper surface of the suction magnet 16 by magnetism, and the holding tube 12 is attached to the outside so that the suction fitting 9 is not displaced. An adhesive or the like is applied to the inside of the holding tube 12 to adhere to the suction magnet 16, and the surface height is made slightly higher than the suction magnet 16.

As a result, in the unlikely event that the wheel 32 is rotating, the lid 32 or other object of the power generation magnet assembly 10 hits the suction fitting 9, and if the impact force is stronger than the suction force of the suction magnet 16, the suction fitting 9 is removed, and the wheel 6 It is possible to prevent the rotation of the lock. However, if the magnetic force of the suction magnet 16 or the magnetic force of the power generation magnet 28 is large and the distance between the two distances can be widened, or if it is used only at a low speed, the suction fitting 9 and the holding tube 12 need not be used. Alternatively, the suction magnet 16 and the suction fitting 9 may be interchanged and reversed.

The inside of the power generation magnet assembly 10 is shown in FIG. 3A, and a cross-sectional view of the BB portion is shown in FIG.
As shown in FIG. 3A, a large hole 39 is formed in the case 24, and the bobbin 17 of the coil 33 is connected to the outer ring of the large hole 39 with an adhesive or the like and fixed to the case 24. A wire coming out of the coil 33 is connected to the light emitting diode 2 through the bridge diode 49 and the resistor 50 by the electric wire 21.
The pipe 23 into which the power generation magnet 28 is inserted is inserted into the coil 33 so that the power generation magnet 28 can freely move inside the pipe 23.

As shown in FIG. 4, the coil 33 is formed by winding a copper wire or enameled wire covered with a polyester resin or the like around the bobbin 17, and the pipe 23 is inserted into the coil 33. A pipe guide 29 is provided on one side of the pipe 23, and the pipe guide 29 and the bobbin 17 on one side are assembled and fixed with an adhesive or the like.

In FIG. 3A, the pipe guide 29 has a hole and is connected to the outer ring of the pipe 23. However, the pipe guide 29 may be connected to the pipe 23 without making a hole. Further, the pipe 23 and the bobbin 17 are connected using the pipe guide 29. However, even if an adhesive is applied to the inside of the bobbin 17 and the outside of the pipe 23 without using the pipe guide 29, the pipe 23 is connected. good.

Furthermore, without fixing pipe guide 29 and the bobbin 17 with an adhesive or the like, inserting a pipe 23 to the pipe guide 29 hits the bobbin 17, by attaching the lid 32 from one side of the pipe 23, the coil in the lid and pipe guide 29 firmly clamp the bobbin 17 of 33, and fixed so that the pipe 23 does not move, it is also possible to exchange or the like can be carried out so the pipe 23. Further, the end portion of the pipe 23 used here is closed in advance so that the power generation magnet 28 does not jump out, and the lid 32 may not be used.

Details of this coil 33 portion are shown in FIG. 4, and the generator magnet 28 and the connecting member 27 are connected with an adhesive or the like, and a cushion 30 is further attached. The material of the cushion 30 may be formed of a sponge, a spring, an air cushion or the like that can absorb impact and sound, absorbs the impact when the power generation magnet 28 moves and hits the case cover 25, It is attached to reduce the impact sound, etc. If it is not necessary for operation, it may not be attached.

Further, the connecting member 27 is used as a guide for allowing the power generating magnet 28 to move smoothly inside the pipe 23 , and is made of a non-magnetic material similar to the cushion 30. If the power generation magnet 28 can move smoothly inside the pipe 23 , these may not be attached.
As a result, only the power generation magnet 28 can be used and operated in the pipe 23. Alternatively, the pipe 23 may be directly attached to the pipe using a bobbinless coil, thereby reducing weight and simplification.

FIG. 5 is a cross-sectional view taken along the line BB in FIG. 3. A large hole 39 is formed in the case 24 , and the bobbin 17 is attached and fixed inside the outer ring of the large hole 39 with an adhesive or the like. the pipe 23 is inserted into the bobbin 17, using an adhesive or the like on one side of the bobbin 17, to fix the pipe 23 with the pipe guide 29. Inside the pipe 23 is inserted power generation magnet 28, the inner pipe 23 can freely move, close covers one side of the pipe 23 in the lid 32.

A cushion 34 is attached to the inside of the lid 32 and is attached to absorb the impact of the power generation magnet 28 and reduce the impact sound, as described above, and may be omitted if not necessary for operation. The lid 32 is preferably formed of a rubber-based material or the like so as to improve the adhesiveness with the pipe 23 and not easily come off, and an adhesive or the like is applied to the tip of the lid 32 and attached to the bobbin 17 and fixed. Alternatively, as shown in FIG. 9, the pipe 23 and the lid 32 may be threaded so that the cushion 34 can be exchanged or foreign matter adhered to the power generation magnet 28 can be removed.

In FIG. 3A, the light emitting diode 2 is attached to the side surface of the case 24 so as to be lit toward the rear of the bicycle. It may be installed with a gap. In this case, the connection to the light emitting diode 2 attached to the case cover 25 needs to make the electric wire 21 long or connect using a male or female connector. (Not shown)

The outer circumferences of the case 24 and the case cover 25 are both uneven, and are strongly connected by fitting such as mating. However, both may be bonded together with an adhesive or the like. Further, a hole 37 is formed in the lower part of the case 24, and when water or the like flows into the case 24 from the outside, the hole 37 is discharged.

As shown in FIG. 3B, the suction plate 7 is attached to the case cover 25 with screws 20, and the rotational movement from the arrow 36 is stopped by the stopper 18. The suction plate 7 is made of a magnetic material such as iron, and the movement of the power generation magnet 28 can be stopped by suction with the power generation magnet 28. As a result, when it is not desired to turn on the light emitting diode 2 such as in the daytime, the suction plate 7 is moved to the stopper 18 position, and when it is desired to be turned on, the suction plate 7 is rotated to the opposite side of the arrow 36 and moved to the holding band connecting plate 22.

The case cover 25 is provided with a screw hole 38 for fixing the holding band connecting plate 22, but an aluminum plate or the like that is threaded is attached to the inner surface of the case cover 25 with an adhesive or the like, and the holding band connecting plate 22 is attached. Tightening with may be strengthened. Further, by changing the angle of the case 24 by a holding band connection plate 22 two and holding band 19 of different lengths the generator magnet assembly 10 in FIG. 1, but it is fixed to the frame 3 by screws 20, the frame 3 The fixing band 19 and the generator magnet assembly 10 may be directly connected without using the holding band connecting plate 22.

In FIG. 3 (B), the holding band connecting plate 22 is bent halfway to form an inclination, the case 24 is inclined, and the return to the spoke 4 side is made smoother by utilizing the weight of the power generation magnet 28 or the like. However, if the return is good, the bending may be eliminated and the inclination may be omitted. Further, the shape of the holding band connecting plate 22 may be changed, and the power generating magnet assembly 10 may be attached by the holding band 19 using the frame 3 and the horizontal frame 68 shown in FIG.

The material of the screw 20, the stopper 18, the case 24, the pipe 23, the bobbin 17, the pipe guide 29, the lid 32, the cushion 34, the connection member 27, and the like has an influence on the movement of the power generation magnet 28 such as aluminum, glass, and plastic as much as possible. Use a non-magnetic material that is not applied. The gap between the inside of the pipe 23, the power generation magnet 28 that moves there, and the pipe 23 and the coil 33 is made as small as possible, and the power generation magnet 28 moves in the coil 33 so that the efficiency of power generation is increased.

Suction by the merits magnet 16 and the generator magnet 28 using neodymium magnet, the magnetic force is very strong because, when used at a normal running, it is possible to separate the two intervals up to about 10 to 20 millimeters, the wheels 6 Therefore, contact with the approach of the attracting magnet 16 caused by the rotation unevenness of the motor can be avoided, and safe power generation can be performed during bicycle travel.

In FIG. 4, the shape of the power generation magnet 28 inserted into the pipe 23 is cylindrical, but the shape of the pipe 23, bobbin 17, etc. is polygonal or other shapes, and the power generation magnet 28 to be inserted and the connection member 27, etc. May be polygonal or other shapes.

The magnetic force of the attracting magnet 16 and the repulsive magnetic force of the power generating magnet 28 is such that when the attracting magnet 16 approaches, the power generating magnet 28 and the connecting member 27 instantaneously move inside the pipe 23 and the cushion 30 can move to the case cover 25. Make it strong. The connecting member 27 and the power generation magnet 28 shown in FIG. 4 may be connected to each other with screws or an adhesive, and may be further covered and connected together with the cushion 30 with a protective cover such as a shrink tube.

While sucking the magnet assembly 8 of the mobile unit in Figure 1 Toritsui one spoke 4, it may be a plurality, and to the traveling direction of the bicycle, although attach to the left, holding band 19 Ya The attachment position of the coil 33 , the light emitting diode 2, etc. in the case 24 may be changed and attached to the right side.

Normally, the power generation magnet 28 of the fixed part is in a free position in the pipe 23. However, as shown in FIG. 1, when the bicycle wheel 6 is rotated, the suction magnet assembly 8 of the moving part fixed to the spoke 4 is fixed. The suction magnet 16 approaches the power generation magnet assembly 10 having the power generation magnet 28, and the magnetic force of the suction magnet 16 and the magnetic force of the power generation magnet 28 begin to repel each other.

In response to the closest approach of the suction magnet assembly 8, the power generation magnet 28 instantaneously moves in the pipe 23 , moves from the upper part of the pipe 23 to the lower part in FIG. 5, and the cushion 30 hits the inside of the case cover 25 to stop the movement. . At this time, a current flows through the coil 33, and the terminal light emitting diode 2 is turned on.

In a normal bicycle, since the spoke 4 is formed of a magnetic material, when the wheel 6 rotates and the suction magnet 16 further moves away, the suction force of the spoke 4 and the power generation magnet 28 and the running magnet The power generation magnet 28 moves to the spoke 4 side due to vibration, repulsion of the cushion 30 , or attraction between the two magnets generated when the attraction magnet 16 moves away during low speed running.

This causes the power generating magnet 28 to move from the lower end to the upper end of the coil 33 in FIG. 5, and a reverse current flows through the coil 33, and the terminal light emitting diode 2 is lit again by rectification of the bridge diode 49. While the wheel 6 is rotating, the power generation magnet 28 is in the vicinity of the spoke 4, moves to the case cover 25 side again when the next attracting magnet 16 approaches, and repeats this.

In the present invention, the power generation magnet 28 can accurately move left and right in the pipe 23 by the suction magnet 16, so that the movement start position of the power generation magnet 28 and the coil 33 and the trajectory at the time of movement are always in the same state. By narrowing the interval between the coils 33, power generation efficiency can be increased and stable power can be generated.

As shown in FIG. 6, the receptacle 42 attached to a side surface of the case 24, connecting the wire 21 to receptacle 42 in parallel with the light emitting diode 2, since it is possible to draw power from the outlet 42, insert the plugs into the receptacle 42 and long connecting wires from plug, when connecting another light emitting diode on the tip, the light emitting diode saddle 1 backward, frame 3, attached by using an adhesive material or clips or the like to the rear end or the like of the fender 5, That part can be lit.

Further, the holding band 19 shown in FIG. 3B may be changed in size and shape and attached to another frame or the like. Similarly, the attachment positions of the suction magnet assembly 8 and the power generation magnet assembly 10 are reversed to perform suction. The magnet assembly 8 may be attached to the frame 3 side, and the power generation magnet assembly 10 may be attached to the spoke 4 side to emit light. Further, a suction magnet assembly 8 instead spoke 4, may be attached to the generator magnet assembly 10 to the lateral frame 68 in its orbit attached to the pedal frame 70 for rotational movement as shown in FIG.

Thereby, the blinking of the light emitting diode 2 can be confirmed from the side or rear of the bicycle at night, and safety can be ensured. Although the embodiment suction magnet assembly 8 is attached by one to the wheel 6, it is also possible to mount a plurality of the center of the wheel 6 to angular different locations on the same orbit, by flashing a plurality of times in one rotation Can do.

The electric power generated from the coil 33 is connected as in the circuit shown in FIG. 10, flows to the bridge diode 49 existing in the case 24, and then is output to the light emitting diode 2 through the resistor 50. The electric power generated in the coil 33 mainly depends on the strength of the magnetic force of the power generation magnet 28, the passing speed, the number of windings of the coil 33, and the like, but the strength of the magnetic force of the power generation magnet 28 and the number of windings of the coil 33 are as follows. Since it is sufficient to determine a value with which the light emitting diode 2 can be turned on by normal rotation, the resistor 50 may be omitted or a plurality of light emitting diodes 2 may be attached.

Since bicycles in recent years have various shapes, materials, applications, etc., the outlet 42, L bracket 43, compression spring 31, etc. are used as shown in FIGS. 6 and 7, and the shape of the power generation magnet assembly 10 in FIG. An embodiment in which the structure can be changed to generate power corresponding to those bicycles will be described with reference to the drawings.

FIG. 6 is a view in which the pipe 23 of FIG. 3 is lengthened and a compression spring 31 is inserted therein, and a cross-sectional view of the AA portion is shown in FIG. The compression spring 31 is inserted into the connection member 26 inside the elongated pipe 41 and connected to the connection member 26 with an adhesive or the like. Similarly, the connecting member 26 is connected to the power generation magnet 28 and another connecting member 27 with an adhesive or the like so that the inside of the pipe 41 can be freely moved. Also, a large hole 39 having the same size is formed in the case cover 25 at the same position as the case 24, and the bobbin 17 is attached to the inner side of the outer ring of the bobbin 17 of the coil 33 and the large hole 39 with an adhesive or the like. Is fixed to the case 24 .

As shown in FIG. 7, a cushion 34 is attached to the lower lid 32 to soften the collision of the connecting member 27 and the compression spring 31 and reduce the impact sound. However, the lower lid 32 itself can absorb the collision. In such a case, the cushion 34 may not be used. An adhesive or the like is applied to the outside of the upper pipe 41, and the pipe 41 is inserted inside the upper lid 32 having the cushion 34, and the pipe 41 and the upper lid 32 are adhered and fixed.

The pipe 41 is inserted into the coil 33 fixed to the outer ring of the large hole 39 of the case 24 and is inserted until the tip of the upper lid 32 contacts the bobbin 17 of the coil 33.
Further, the pipe collar 40 is inserted outside one side of the pipe 41 , and the lower lid 32 having the cushion 34 is continuously inserted until the pipe collar 40 contacts the bobbin 17, so that the pipe 41 does not move in the coil 33. Secure firmly.

The lid 32 is made of a rubber material that can be in close contact with the pipe 41, and the pipe collar 40, pipe 41, lid 32, cushion 34, etc. are non-magnetic substances that do not affect the movement of the power generation magnet 28 as much as possible. use. As a result, when the inside of the pipe 41 is worn by friction when the pipe 41 and the power generation magnet 28 move, the lower lid 32 and the pipe collar 40 can be removed and the pipe 41 can be replaced.

In FIG. 6, the position of the suction plate 7 is moved from the position of FIG. 3 so that the suction plate 7 can be moved by the screw 20 or the like and comes into contact with the side surface of the pipe collar 40 or the lower lid 32. Thereby, like Example 1, the movement of the power generation magnet 28 inside the pipe 41 can be stopped, and this can be used when lighting such as daytime is desired to be avoided. The length and presence of the pipe collar 40 are determined according to various conditions such as the moving distance of the power generation magnet 28 and the length of the compression spring 31 , and may not be used when the pipe 41 becomes short.

The operation is almost the same as in the first embodiment, and a part of the structure and details of the operation are omitted. However, when the bicycle wheel 6 rotates, the suction magnet 16 of the suction magnet assembly 8 fixed to the spoke 4 is replaced with the power generation magnet. The magnetic magnet of the suction magnet 16 and the magnetic power of the power generation magnet 28 begin to repel each other and the power generation magnet 28 instantaneously moves in the pipe 41 with respect to the closest approach of the suction magnet assembly 8. 7 moves from the upper part to the lower part of the coil 33, the compression spring 31 hits the cushion 34 of the lower lid 32, and the movement stops when the compression spring 31 further contracts.

At this time, a current flows through the coil 33, and the terminal light emitting diode 2 is turned on. When the wheel 6 further rotates and the attraction magnet 16 is separated and the repulsive force of the magnetic force is weakened, the power generation magnet 28 coupled to the connection member 26 is moved to the spoke 4 side of the original position by the repulsive force of the compression spring 31.
This operation is performed instantaneously even when the bicycle is traveling at a low speed. This causes the power generation magnet 28 to move from the lower end to the upper end of the coil 33, and a reverse current flows through the coil 33. The terminal light emitting diode 2 is turned on again.

Normally, the generator magnet 28 is in the vicinity of the spoke 4 with respect to the coil 33 due to the influence of the compression spring 31 or the like while the wheel 6 is rotating or stopped, and moves again into the coil 33 when the next attracting magnet 16 approaches. To generate electricity and repeat this.

As described in the first embodiment, in the normal bicycle, the spoke 4 is formed of a magnetic material. Therefore, the attraction force between the spoke 4 and the power generation magnet 28 during the bicycle traveling and the vibration during the low-speed traveling. The power generation magnet 28 moves and is on the spoke 4 side due to the attractive force between the two magnets generated when the suction magnet 16 moves away. However, when the spoke 4 is a non-magnetic material or between the power generation magnet 28 and the spoke 4 When the magnetic attractive force is weak or when rotating at high speed or the like, the operation is unstable and it is difficult to reliably light the terminal light emitting diode 2 .

However, by attaching the compression spring 31, the position of the power generation magnet 28 can always be moved to the spoke 4 side, so that it can be lit reliably. In FIG. 7, the compression spring 31 is inserted into the connection member 26, but the diameter of the compression spring 31 may be increased to contact the connection member 26 in a free state, and the cushion 34 of the lower lid 32 may be attached. The compression spring 31 may be directly fixed to the lower lid 32 with screws or the like.

Also instead of using compression springs 31, telescoping cushion or rubber, to repel the plate spring or the like generating magnet 28 may be used those which can be moved, the magnet polarity which gives a repulsive force to the generator magnet 28 bottom of It may be attached to the lid 32 and the power generation magnet 28 may be repelled and moved to the spoke 4 side.

In FIG. 7, there is a gap between the lower cushion 34 and the compression spring 31, but the repulsive force of the compression spring 31 , the repulsive force of the magnetic force of the power generation magnet 28 and the suction magnet 16 , and the cushion 34 can be balanced, If the generator magnet 28 can move the upper and lower ends of the coil 33 may not open, the lower lid 32, as shown in FIG. 9 further, the lower portion of the lid 47 and the pipe 41 machined screw, the compression spring 31 You may enable it to adjust expansion-contraction strength. However, in this case, it is necessary to remove the pipe collar 40 and bond the pipe guide 29 to the pipe 41 as in the first embodiment.

The connection method of the connecting member 27, the power generating magnet 28 and the connecting member 26 in FIG. 7 may be connected to each other with screws or adhesive, and may be further covered with a protective cover such as a shrinkable tube. However, each connecting member may not be used when the pipe 41 can move smoothly in the pipe 41 .

As in the first embodiment, in the present invention, the power generation magnet 28 can accurately move left and right in the pipe 41 by the attracting magnet 16, so that the movement start position of the power generation magnet 28 and the coil 33 and the trajectory during the movement are always in the same state. By reducing the distance between the power generation magnet 28 and the coil 33, power generation efficiency can be increased and stable power can be generated.

  In the case of FIG. 7, when the length of the compression spring 31 and the length of the pipe 41 are changed and the magnetic force of the power generation magnet 28 and the suction magnet 16 is further increased to increase the mutual repulsive force, the moving distance of the power generation magnet 28 is When the power generation magnet 28 reaches the lower end of the coil 33 from the upper end of the coil 33, the first power generation is performed, and the output is output to the bridge diode 49.

If the movement continues further and the entire power generation magnet 28 passes the lower end of the coil 33 , a current in the opposite direction flows to the coil 33 this time. Subsequently, when the power generation magnet 28 passes through the upper end from the lower end of the coil 33 due to the repulsion of the compression spring 31 , the same power generation is performed again, and both are rectified by the bridge diode 49 and the light emitting diode 2 is turned on four times in one reciprocation. Can do.

6 and 7, when the magnetic force between the power generation magnet 28 and the suction magnet 16 is increased and the power generation magnet 28 has a distance that is not affected by other magnetic materials such as the spokes 4 other than the suction magnet 16, the compression spring 31. A similar operation may be performed using a stretchable tension spring or rubber instead of the above. In this case, the tension spring is fixed to the lower cover 32 on the case cover 25 side, the opposite side of the tension spring is connected to the connecting member 26 or directly to the power generation magnet 28, and the opposite polarity of the suction magnet 16 is the same as the polarity of the power generation magnet 28 . Make sure they are different and suck each other.

As a result, when the wheel 6 rotates and the attracting magnet 16 approaches, the power generation magnet 28 is attracted, moves from the lower end to the upper end of the coil 33 in FIG. 7, current flows through the coil 33 , and the light emitting diode 2 is turned on. When the wheel 6 is further rotated and the attracting magnet 16 is separated and the magnetic force is weakened, the power generation magnet 28 instantly moves from the upper end to the lower end of the coil 33 due to the tension of the tension spring, and a reverse current flows again through the coil 33. The light-emitting diode 2 can be lit again by being rectified by the bridge diode 49 . (Not shown)

Also, the tension spring may be attached to the lower lid 32 by attaching it to the lid 47 when threaded as shown in FIG. 9 so that the tensile strength can be adjusted. Alternatively, an object that can pull and move the power generation magnet 28 may be used. (Not shown)

Next, other embodiments will be described with reference to the drawings.
As shown in FIG. 6, the L metal fitting 43 is attached to the side surface of the case cover 25, and the screw 20 is inserted into the elongated hole 44 to be connected to the L-shaped fixing plate 45. The L-shaped fixing plate 45 is connected to the holding band connecting plate 22 and further connected to the holding band 19 ahead.

As a result, the distance between the suction fitting 9 of the suction magnet assembly 8 and the upper lid 32 of the power generation magnet assembly 10 is adjusted so that the position of the elongated hole 44 of the L fitting 43 is adjusted, and the angle, attachment position, By changing the size and shape, it can be attached to various types of bicycles and operated at the optimum distance.

Also, instead of using L brackets 43 and L-shaped fixing plate 45, between the case cover 25 and the holding band connection plate 22 and screws 20, or input is a spacer or the like between the case cover 25 and L brackets 43, The distance between the upper lid 32 and the suction fitting 9 of the suction magnet assembly 8 may be adjusted.

Generated power of the present invention is 20 mA, and it is possible to emit light emitting diode 2 few moments 13,000Mcd, the mounting receptacle 42 to the side surface of the case 24 in FIG. 6, the electric wire to the receptacle 42 in parallel with the light emitting diode 2 When connected at 21 , power can be taken out from the outlet 42.

Thereby, insert the plug into the outlet 42, a line from the plug connected to the other light-emitting diodes, when permanently installing clips, etc. to the light emitting diode, a saddle 1 rear frame 3, the rear end or the like of the fender 5 It can be attached and the part can be lit.

FIG. 8 (A) is a diagram in which the suction magnet holding plate 11 of FIG. 2 (A) of the first embodiment is enlarged, the suction magnet 16 and its accompanying parts are added, and two sets are mounted. The opposite is to keep the distance between them as much as possible.

With respect to the rotation direction of the wheel 6 , the polarity of the first attracting magnet 16 is set so as to repel the power generating magnet 28, and the polarity of the next attracting magnet 16 is attracted with the generating magnet 28. As a result, when the attracting magnet assembly 8 is used in the same shape as that of the first embodiment, and the wheel 6 rotates, the power generation state of the first power generating magnet 28 is the same as that of the first embodiment. Electric power is generated by the described operation, and the light emitting diode 2 is turned on.

When the wheel 6 further rotates and the next attracting magnet 16 approaches, the power generating magnet 28 is attracted and instantaneously moves to the spoke 4 side. As a result, the power generating magnet 28 can be moved without using the compression spring 31 of the second embodiment, and even when the wheel 6 is rotated at high speed, it can be moved more reliably if the distance between the two attracting magnets 16 is increased. Therefore, the spoke 4 can be adapted to a non-magnetic material.

Note that the order of the polarity of the suction magnets 16 attached to the suction magnet holding plate 11 may be any, and two pairs of the suction magnet assemblies 8 of the first embodiment are attached to the different spokes 4 so that the polarity of each of the suction magnets 16 is changed. The operation may be reversed.

In FIG. 8B, the shape of the attracting magnet holding plate 11 is vertically long, so that the position of the attracting magnet 16 can be moved up and down with respect to the cross portion of the spoke 4, and the position of the cross portion differs depending on the bicycle. On the other hand, the mounting position of the power generation magnet 28 can be changed greatly, and it can respond to the wheels 6 of various shapes.

FIG. 8C shows the case where the position of the attracting magnet 16 is moved with respect to the cross part of the spoke 4 with (B) sideways. Thus, the mounting position of the power generation magnet 28 can be greatly changed, and the wheel 6 having various shapes can be handled.

2 and 8, the suction magnet 16 is attached to the suction magnet holding plate 11 side. However, in the case of a bicycle or the like in which the spoke 4 and the frame 3 are sufficiently separated from each other and the rotation of the wheel 6 and the safety are not hindered. The suction magnet holding plate 14 and the suction magnet holding plate 11 may be reversed, and the suction magnet 16 may be attached to the suction magnet holding plate 14 side.

FIG. 9 is a view in which a cut 46 is made in the upper side surface of the pipe 41 in FIG. 7 of the second embodiment.
This notch 46 is made by using a laser or a cutter to nearly half the thickness of the pipe 41 , the wheel 6 rotates, the object attached to the spoke 4 or the suction magnet 16 hits from the direction of the arrow 48, and external force is applied. When you join, it will break from this part. As a result, it is possible to avoid the wheel 6 from being locked and suddenly stopped between the power generation magnet assembly 10 and the spokes 4 and the like, thereby further improving safety.

In FIG. 9, the cut 46 is made inside the coil 33 , but it may be moved to the upper side, or cut from this cut 46 portion, and the pipe 41 is divided into two parts, and this portion is bonded. It may be bonded with a weak material and bend when an impact is applied to this part from the outside. The material of the pipe 41 may be made of a material such as glass that is damaged when an excessive impact is applied.

In FIG. 9, the lower part of the pipe 41 in FIG. 7 of the second embodiment is threaded, and the material of the counterpart lid 47 is changed to an aluminum or plastic system that can be threaded. The pipe collar 40 is removed, and the pipe guide 29 used in the first embodiment is attached to the outside of the pipe 41 to be connected and fixed.

Covered with a top lid 32 from the upper tip of the pipe 41, the tip of the upper lid 32 is a pipe 41 hits the bobbin 17 is prevented from moving in the coil 33.

As a result, when the inside of the pipe 41 is worn by friction caused when the pipe 41 and the power generation magnet 28 move, the upper cover 32 is removed, the pipe 41 is removed from the case cover 25, and the pipe 41 is replaced. it can also be adjusted by turning the lid 47 of the screw processed side of the moving distance of the compression spring 31.

Incidentally, the connection in this case Example 1 similar pipe 41 and the bobbin 17, the pipe guide directly pipe 41 and the bobbin 17 without using the 29 and fixed by connecting with an adhesive or the like, the pipe 41 to enforce only threading The exchange may not be performed.

Next, an embodiment in which the pipe 41 portion is separated from the coil 33 and the position and angle of the pipe 41 can be adjusted and exchanged will be described with reference to the drawings.
FIG. 11 shows that the parts inside the pipe 41 of FIG. 6 are left as they are, the outer pipe collar 40 is removed, the pipe 41 with the lid 32 attached to both ends is separated from the coil 33, and the pipe 41 is pressed by the saddle 52, FIG. 5 is a perspective view in which a saddle 52 is fixed to a pipe holding plate 53 with a screw 20 and is further attached to a case cover 25.

Since the pipe 41 and the lid 32 are fixed with the screw 20 by the saddle 52, when the screw 20 is loosened, the pipe 41 can be moved, the angle can be changed, and the pipe 41 can be exchanged.

Thereby, the positional relationship between the power generation magnet 28 and the coil 33 can be changed, and when the suction magnet 16 moves away by changing the angle downward, the power generation magnet 28 and the connection member 27 are weighted to generate power. magnet 28 is moved to the spoke 4 side, the generator magnet 28 is likely to move to the original position, it is possible to reduce the size and length of the compression spring 31 and will, also if only low-speed running, the compression spring 31 It can be omitted.

Furthermore, the pipe 41 can be easily replaced when the inside of the pipe 41 is damaged due to friction accompanying the movement of the power generation magnet 28 .

Next, an embodiment in which the pipe 23 is deleted and the power generation magnet 28 can move in the coil 33 will be described with reference to the drawings.

A repulsive magnet 55 having a polarity repelling the polarity of the power generation magnet 28 is fixed to the case cover 25. This magnetic force moves the power generation magnet 28 of the fixed portion into the coil 33 when the attracting magnet 16 of the moving portion is closest, and further When the attraction magnet 16 is separated, the power generation magnet 28 is repelled so that it can move instantaneously to the original position on the spoke 4 side.

A stop plate 56 for adjusting the moving width of the power generation magnet 28 is fixed to the case 24. The stop plate 56 is structured so that the moving width can be adjusted. Further, the magnet holding plate 57 , the stop plate 56 , A cushion or the like is attached between the cases 24 so that the shock can be absorbed.
Thus, when the suction magnet 16 of the movable portion is closer than the arrow 58 direction by the repulsive force, power magnet 28 of the fixed part is moved to the inner coil 33, current flows through the coil 33, lights the light emitting diode 2.

When the wheel 6 further rotates and the attracting magnet 16 is separated and the repulsive force is weakened, the repulsive force of the power generating magnet 28 and the repelling magnet 55 causes the power generating magnet 28 to instantaneously move through the coil 33 to the original position. A reverse current flows through the coil 33 and is rectified by the bridge diode 49 , so that the light emitting diode 2 can be lit again.

In FIG. 12, the repulsion magnet 55 is used to return the power generation magnet 28. However, as in the second embodiment, the case cover 25 is perforated so that the compression spring 31 can be attached and the repulsion of the compression spring 31 is used.

Further, a tension spring 64 is connected to the other end of the power generation magnet 28 , and the tension spring 64 is fixed to the fixed base 65 through the coil 33.

In operation, when the attracting magnet 16 of the moving part approaches, the repulsive magnet 61 moves away in the direction of the arrow 60 due to the repulsive force of both magnets, pulls the wire 63 , moves the power generating magnet 28 in the coil 33 , and pulls the tension spring 64 . . Although this operation depends on the moving speed of the attracting magnet 16 , it is normally performed instantaneously, a current flows through the coil 33 , and the light emitting diode 2 is turned on.

When the attracting magnet 16 is further separated and the repulsive force is weakened, the power generation magnet 28 instantaneously moves to the original position through the coil 33 due to the pulling force of the tension spring 64 , and a reverse current flows through the coil 33 again.
