The present invention relates to a generator for a vehicle that recovers energy to generate electricity. More specifically, a tire filled with air pressure maintains a shape near a full circle without a load applied thereto, but the weight of the vehicle body is a tire. When it is applied to, the part contacting with the ground is crushed and is forced to contract. When the wheel continues to rotate and is out of this point, where the load is concentrated, the retracted tire is inflated and restored again by the internal air pressure of the tire. It relates to a generator for generating electricity by using as a power source.

As a generator for a vehicle that recovers and generates energy in the related art, a power generation method using a braking force generated when a vehicle is braked as a power source for power generation, and a shock absorber generated by a shock absorber while driving is used to generate power. There is a power generation method that generates electricity by using as a necessary power source. As such, the power generation method using the braking force and the buffering force of the vehicle as the power source required for power generation has the effect of saving energy because it generates power by recovering energy discarded by frictional heat. However, these methods have the disadvantage that it is difficult to continuously and stably develop energy because it can recover energy only during braking or only when buffering occurs due to shaking of the vehicle body.

The present invention has been made in view of the above.

In the vehicle power generation system for electrically converting the contraction and expansion kinetic energy generated during the rotation of the tire under the load of the vehicle as described above, the disk-shaped fastening connected to the bolt of the axle to which the wheel wheel is fastened A plurality of conductor coils are radially arranged on the attachment to attach a plurality of conductors, and a plurality of cylinders are attached to the attachment to correspond to the power coil. In addition, the cylinder has a shaft axis for reciprocating movement, and the contact member that is in close contact with the outer peripheral surface of the tire shaft in order to transfer the contracted and expanded movement of the tire in contact with the ground to rotate the shaft axis, and to one end of the stem shaft At the other end, a rod-shaped magnet body is attached. At this time, when the tire is contracted and inflated by the rotation of the wheel, this movement reciprocates the rod shaft, and this reciprocating movement generates electricity by acting on the coil, the conductor of the magnet body attached to the rod shaft.

Accordingly, an object of the present invention is to recover the force that the tire contracts and expands due to the weight of the vehicle body and the air pressure of the tire at the time of rotation of the wheel, and to use it as a power source for power generation, without the need for additional energy input while driving the vehicle. To generate electricity.

Particularly, in the power generation system of the present invention connected to the bolt of the axle to which the wheel wheel is fastened, the shaft shaft structure contracts with the ground while rotating with the tire, and the tire continues to rotate. This point is to expand the expansion, there may be a problem such that the contraction and expansion of the rod shaft causes a rotational resistance to the wheel, but the reciprocating motion of the rod shaft does not cause a rotational resistance in the rotation of the wheel. This is because the rotating wheels have the least frictional resistance, which is the rolling resistance when the complete wheel is maintained like the wheel of a train, and the rolling resistance of the wheel increases as the circular shape is lost. That is, since the contact member hardly protrudes out of the outer circumferential surface of the tire when the rod shaft is inflated, the tire keeps its original shape and the wheel rotates so that no rolling resistance is generated. The force is generated, which acts as a force to prevent the tire from contracting, thereby acting as a force that keeps the tire in the shape of a circle, thereby reducing the rolling resistance of the tire.

Accordingly, an object of the present invention is to provide a power generation system for a vehicle that generates electricity by collecting energy and recovering energy.

(First embodiment)

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

1 is a perspective view illustrating a state in which a vehicle generator system according to the present invention is fastened to a wheel, FIG. 2 is a side view of FIG. 1, FIG. 3 is an operating state diagram of FIG. 1, and FIG. 4 is a power generation nose of FIG. 1. Some are side views showing another embodiment, FIG. 5 is an enlarged perspective view of part "A" of FIG. 4, and FIG. 6 is a perspective view showing another embodiment of the contact member of FIG.

The disk-shaped attachment 10, which is a structure of the power generation system of the present invention, is connected to the bolt 19 of the axle to which the wheel wheel 19 is fastened by connecting the fastening nut 10a of the attachment 10 to the side of the wheel 19. Therefore, the disk-shaped attachment 10 fastened to the wheel shaft is a structure that rotates with the wheel. A plurality of power coils 11 are disposed radially around the origin and attached to the attachment 10. The power generating coil 11 has a cylindrical shape, and a wire material 17, which is a conductor, is wound around a cylindrical non-conductor. The hollow coil is formed at the center of the power generating coil 11 so that a rod-shaped magnet body 12 can be inserted and drawn out. Formed and provided. In addition, when the magnet body 12 is inserted into the hollow part of the power coil 11, the inner circumferential surface of the hollow part and the outer circumferential surface of the magnet body 12 have a diameter such that a coefficient of friction does not occur. In addition, a plurality of cylinders 13 corresponding to the power generation coils 11 are attached to the attachment 10, and a rod shaft 14 is inserted into the cylinder 13 to reciprocate. At this time, the rod shaft 14 is inserted into the inner surface of the cylinder 13 through a bearing (not shown) to reduce the coefficient of friction. Therefore, the rod shaft 14 can slide so that the friction coefficient hardly occurs when the cylinder 13 reciprocates in the axial direction. In the rod shaft 14, a contact member 15 which is always in close contact with the outer circumferential surface of the tire 18 is connected to and attached to one end portion thereof, and a magnet body 12 is attached to the other end portion thereof. In addition, a spring 16 is inserted into the rod shaft 14 between the magnet body 12 and the cylinder 13 so that the contact member 15 is always on the outer circumferential surface of the tire 18 by the elastic force of the spring 16. Make sure they are in close contact. The magnet body 12 is a permanent magnet whose one end is an N pole and the other end is an S pole, and the magnetic field is changed by reciprocating the insertion and withdrawal in the axial direction to the hollow formed in the power generation coil 11, This change causes electromotive force due to electromagnet induction, and the generated current flows into the wire material 17. The terminal (not shown) of the electric wire material 17 can be used as a drive source of a drive motor or the like, or can be connected to a charging device for a power source.

The power generation system of the present invention configured as shown in FIG. 1 functions as follows.

The wheel for a vehicle fits the tire 18 to the wheel 19, and pressurizes the air inside it, and is used. The reason why the tire 18 is pressurized and used in this way is that the riding comfort is superior to that of using the rigid wheels. However, in this method, because the weight of the vehicle body (500) is in contact with the ground of the tire is crushed to lose the shape of the circle, the rotational resistance of the wheel is generated. The tire 18 of the 500 is crushed and contracted, and the degree of contraction is not constant, but generally about 20 to 30 mm is crushed and contracted.

In the operation of the power generation system of the present invention using the above-described principle, since the operation of the power generation system does not occur when the vehicle is stopped, that is, the rotation of the wheel does not occur, no change in the magnetic field occurs, and the wire material 17 of the electrical wiring part. Even though no current flows.

However, when the tire 18 rotates, the disk-shaped attachment 10 fastened to the wheel shaft also rotates together. The load of the vehicle body is concentrated at the point 500 where the tire 18 is in contact with the ground, and the tire 18 is crushed and contracted by the portion 500 in contact with the ground. At the same time, the contact member 15 located at the point where the tire 18 is retracted is also retracted by the distance at which the tire 18 is retracted.

The contraction of the contact member 15 causes the rod shaft 14 connected to the rod shaft 14 to be contracted in the axial direction so that the rod-shaped magnet body 12 attached to the rod shaft 14 is moved into the hollow portion of the cylindrical power coil 11. Move it to insert.

At this time, since the rotation of the tire 18 continues to proceed, the contact member 15 closely attached to the outer peripheral surface of the tire also rotates together. Therefore, when the tire 18 continues to rotate and leaves the point 500 where the load is concentrated, the portion that has been contracted by the air pressure inside the tire expands. At the same time, the inflating tire 18 also expands the contact member 15 in close contact with the outer circumferential surface of the tire 18.

The expansion of the contact member 15 expands and moves the rod shaft 14 connected thereto in the axial direction, and also expands and moves the magnet body 12 attached to the rod shaft 14 in the axial direction. That is, due to the contraction of the tire 18, the magnet body 12 inserted into the hollow portion of the power generation coil 11 exits with the expansion of the tire 18.

The spring 16 inserted into the rod shaft 14 between the cylinder 13 and the magnet body 12 has an outer circumferential surface of the tire 18 by applying an elastic force to the rod shaft 14 toward the power generation coil 11. The contact member 15 located in the always to be in close contact with the outer peripheral surface of the tire (18). At this time, the centrifugal force generated by the rotation of the tire 18 acts as a force to detach the rod shaft 14 attached to the attachment 10 and the contact member 15 connected thereto. Therefore, it is preferable that the spring 16 uses a spring 16 having a larger elastic force than the centrifugal force generated in the rod shaft 14 and the contact member 15.

As the wheel continues to rotate as described above, the tire 18 is contracted and inflated, and this movement is transmitted to the rod shaft 14 and the magnet body 12 attached to the rod shaft 14 is By reciprocating motion in the axial direction with respect to the cylindrical power generation coil 11, a magnetic field change is generated in the power generation coil 11, which causes electromotive force to be generated by the electromagnetic petroleum to flow the current to the wire material 17. In this case, the current may be taken out by inserting the second bushing 17b into the first bushing 17a attached to the center of the attachment 10 in order to flow current to the storage battery or the driving unit.

Accordingly, in the present invention, when the tire 18 contacts the ground by the vehicle body load, the portion 500 is crushed and contracted, and when the tire 18 is out of the point 500 where the load is concentrated, the tire 18 is contracted by the internal air pressure of the tire 18. The effective use of energy can be promoted by using the force of the expansion and restoration of the old part as a power source for power generation. That is, it is also possible to use the electricity generated by the generator of the present invention by connecting to another drive motor, or to be connected to the charging device of the power source.

In addition, the function of the contact member 15 in contact with the ground in the process of being in close contact with the outer peripheral surface of the tire 18 may also provide an additional function of suppressing the slip from the sliding of the road surface, such as winter.

(Example of transformation)

4 is the same in principle as the first embodiment of FIG.

As shown in FIG. 1, the cylinder 13, the rod shaft 14, the spring 16, the contact member 15, and the like are attached to the attachment 10 in the same manner, except that the magnet body is attached to the rod shaft 14 ( 12 '), the direction of the magnetic pole and the shape of the power generation coil (11') and the number and position to be laid are different.

An example of the modification will now be described with reference to FIG. 4.

In FIG. 4, only one power generation coil 11 ′ is laid in the central point of origin of the disc-shaped attachment 10.

The power generation coil 11 'is composed of a non-conductor and a wire material 17, wound around the wire member 17 spirally on the outer circumference of the non-conductor, and wound in the same direction. The power coil 11 ′ wound as described above is attached to the attachment 10 so that the axial direction of the wheel shaft to which the wheel 19 is fastened and the axial direction of the non-conductor shaft core to which the wire material 17 is wound are the same.

At this time, the magnet body 12 'acting on the power coil 11' attached as described above acts on the side of the power coil 11 'to change the magnetic field. That is, since the reciprocating motion of the magnet body 12 'attached to the rod shaft acts on the side of the power generation coil 11', the magnetic pole direction is such that the N pole and the S pole are located laterally with respect to the axial movement direction.

This structure has a plurality of magnet bodies attached to the rod shaft 14 in the rod shaft 14 which is inserted into the plurality of cylinders 13 radially attached to the disc-shaped attachment 10 and reciprocates. Since 12 'acts on one power generation coil 11' built up in the center of the attachment, the relative velocity of the magnetic field and the conductor is higher than that of FIG.

This is because, when the wheel is rotated once, FIG. 1 shows that the magnetic field 12 is changed in one reciprocating motion with respect to each power coil 11, but FIG. 4 shows a plurality of magnetic bodies. This is because (12 ') concentrates on only one power coil (11') located in the center. That is, in FIG. 1, the power generation coil 11 and the magnet body 12 correspond to 1: 1, whereas in FIG. 4, a plurality of magnet bodies 12 'correspond to one power generation coil 11'.

Therefore, when the wheel is rotated once, the number of magnetic field changes generated in the power coil 11 'of FIG. 4 is generated by a plurality of magnet bodies 12', which increases the relative speed of the magnetic field and the conductor, thereby increasing the electromotive force. As a result, power generation efficiency increases.

The modified embodiment of FIG. 6 has the same principle as the first embodiment of FIG. 1 and the modified embodiment of FIG.

However, the modified embodiment of FIG. 6 replaces the contact member 15 which is connected to and attached to the distal end of the rod shaft 14 in the embodiment of FIGS. 1 and 4, in FIG. 6 of the rod shaft 14. The roll wheel 20 is attached to the distal end.

A description with reference to FIG. 6 is as follows.

In the rod shaft 14 inserted into the cylinder 13 to perform an insertion movement, the roll wheel 20 is fastened and attached to the distal end of the rod shaft 14 facing toward the outer circumferential surface of the tire 18. At this time, when the rod shaft 14 inserted into the cylinder 13 is expanded, the outer circumferential surface end point of the roll wheel 20 attached to the end portion of the rod shaft 14 is the outer diameter of the tire 18 of the unshrinkable portion. It is preferable to make it equal to the outer diameter of phosphorus.

Because, when the rod shaft 14 is inflated, if the outer circumferential surface portion of the roller wheel 20 protrudes larger than the outer diameter of the tire 18 of the unshrinkable portion, the protruding portion of the roller wheel 20 rotates. This is because the wheel acts as a rolling resistance.

In addition, a spring 16 is inserted into the rod shaft 14 between the roller wheel 20 and the cylinder 13. The spring 16 acts as an elastic force to pull out the magnet body 12 inserted into the hollow of the power generation coil 11. That is, due to the contraction of the tire 18 acts as a force to pull out the magnet body 12 inserted into the hollow portion of the power generation coil (11).

In order to prevent the rod shaft 14 from completely exiting the cylinder 13 when the rod shaft 14 expands with the elastic force of the spring 16, the magnet body is larger than the diameter of the rod shaft 14 axially moving in the cylinder 13. The diameter of the rod shaft 14 of the site | part to which (12) is attached is formed large and provided. Since the elastic force of the spring 16 inserted into the shaft 11 acts on the stem shaft 14 inserted into the cylinder 13 in the direction of the tire 18 outer circumferential surface, This is because the rod shaft 14 will escape from the cylinder 13 if not caught by (13).

At this time, the range of the rod shaft 14 that is expanded by the force of the spring 16 is the outer diameter of the tire 18 of the end portion of the roll wheel 20 attached to the distal end of the shaft 14 is not contracted It is desirable to only inflate by a distance that matches.

In the case where the roller wheel 20 is attached and operated at the end of the rod shaft 14 as described above, even when the tire 18 wheel is idle in contact with the ground, the roller wheel 20 is in contact with the ground. Since the rotation of the roll wheel 20 is made almost no rotational frictional resistance, it is possible to protect the structure such as the rod shaft (14).

(2nd embodiment)

In the second embodiment, the tire is contracted and crushed at a portion where the tire is in contact with the ground due to the vehicle body load. In this case, a shape in which both sides of the tire tire are protruded is used. Therefore, the second embodiment is the same as the first embodiment. Hereinafter, a second embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

7 is a perspective view illustrating a second embodiment of a vehicle generator according to the present invention, and FIG. 8 is a side view of FIG. 7.

The wheel wheel 19 is connected to the bolt fastening to the wheel rotation side of the vehicle to fasten the disk-shaped attachment 70 to the wheel side portion. The attachment 70 is attached to a plurality of lever fixing rods 79 arranged radially on the basis of the origin, and the lever lever 79 is provided with a lever 78. At this time, one end of the lever 78 is in close contact with the side portion of the tire 18, and the other end is attached to the magnet body 72.

In addition, a cylindrical power generation coil 71 is arranged in the attachment so that the magnet body 72 acts to generate a current. The power coil 71 is wound in the same direction spirally around the cylindrical outer circumference, which is a non-conductor, and a hollow portion is formed at the center of the power coil 71 so that a rod-shaped magnet body 72 can be inserted and drawn out. The hollow part has a gap such that the friction coefficients do not occur with each other during the insertion and withdrawal of the rod-shaped magnet body 72. At this time, the magnetic pole 72 of the magnet body 72 attached to the lever 78 has an N pole in the axial movement direction with respect to the winding coil 71 and an S pole in the other.

Then, a spring 76 is arranged between the side portion of the lever 78 at the position where the magnet body 72 is attached and the attachment. The spring 76 acts an elastic force on the lever 78 so that one end point of the lever 78 always comes into close contact with the side surface of the tire 18, and the magnet body 72 moves and winds up. After being inserted into the coil 71, the magnet body 72 also acts as an elastic force for exiting again. At this time, the elastic force of the spring 76 is weaker than the force from which the tire 18 protrudes, and preferably the elastic force is greater than the size of the attraction force acting when the magnet body 72 inserted into the power generation coil 71 exits.

Looking at the operating state of the second embodiment configured as described above are as follows.

When the tire 18 receives the load, the side contacting the ground is crushed, and the side portion protrudes. At this time, the end portion of the lever 78 is in close contact with the side portion, so the lever 78 is also protruded as it protrudes. . At the same time, the magnet body 72 located in the opposite direction with respect to the lever holder 79 is inserted into the hollow portion of the winding coil 71.

At this time, when the wheels continue to rotate in contact with the ground and crushed out of this point, the parts that protruded by the air pressure inside the tire 18 are contracted and restored. At the same time, the elastic force of the spring 76 built up between the lever 78 and the attachment 70 acts to push the lever 78 so that the magnet body 72 attached to the lever 78 is connected to the winding coil 71. Escape from inside

As described above, the protruding and contracting motion of the side of the tire 18 transfers the motion to the lever 78, and the magnet body 72 attached to the lever 78 acts on the winding coil 71 to change the magnetic field. Happens. In the change of the magnetic field, electromotive force is generated by electromagnetic induction, and a current flows into the wire material 77. In this case, the wire material 77 may be connected to a storage battery to store electricity, or may be used as a power source by connecting to other driving systems.

(Example of transformation)

9 is the same operation principle as FIG. The purpose of the configuration different from that of FIG. 7 is to increase the relative speed of the magnetic field and the conductor as shown in FIG. 4. Hereinafter, with reference to the accompanying drawings will be described in detail.

9 is a perspective view illustrating another embodiment of the power generation coil unit of FIG. 7, FIG. 10 is an enlarged perspective view of a portion “B” of FIG. 9, FIG. 11 is a cutaway view of FIG. 10, and FIG. It is a cross section of 10.

Only one power generation coil 81 is laid at the center of the origin of the attachment 70, and one magnet body 82 acts on the power generation coil 81.

A plurality of lever holders 79 are radially attached to the attachment 70, and a lever 78 is installed on the holders 79. One end of the lever 78 is in close contact with the side surface of the tire 18, and the other end is in close contact with the end face of the magnet mounting plate 84 arranged in the center. A rod-shaped magnet body 82 is attached to a central portion of the cross section opposite to the magnet mounting plate 84.

A cylindrical power generating coil 81 is formed in the center of the origin of the attachment 70, and at this time, a hollow portion is formed in the center of the power generating coil 81, and a rod-shaped magnet body 82 is inserted into the hollow portion. It is designed to be pulled out, and the gap is so large that friction coefficient does not occur during insertion and withdrawal.

The second spring 86a is inserted into the cylinder 83 between the magnet mounting plate 84 and the power generation coil 81 to pull out the magnet body 82 inserted into the power generation coil 81 to the outside. The end portion of the lever 88, which is in contact with the side surface of the tire 18, is always arranged on the lever 78 by constructing a spring 76 at a position between the lever holder 79 and the magnet mounting plate 84. Make sure they are in close contact. At this time, it is preferable that the magnitude of the two forces that add the elastic force of the second spring 86a and the spring 76 is smaller than the force from which the tire 18 protrudes due to the vehicle load.

The operation of FIG. 9 configured as described above is as follows.

When the wheel rotates, the attachment 70 attached to the rotating shaft of the vehicle also rotates together. At this time, the tire 18 is crushed by the load of the vehicle at the point of contact with the ground, both sides of the tire 18 is protruded to a certain portion. At this time, when the lever 78 attached to the attachment 70 reaches the point where the tire 18 rotates and protrudes, the distal end of the lever 78 closely attached to the side of the tire 18 protrudes from the tire 18. As much as it protrudes. The projecting motion transmitted to the lever 78 presses the magnet mounting plate 84 located at the center of the attachment 70 to insert the magnet body 82 into the power generation coil 81. At this time, if the wheel continues to rotate out of the point of contact with the ground, that is, out of the point where the load was concentrated, the tire 18 is contracted, recovered by the internal air pressure. At the same time, the force that pressed the lever 78 in the direction of the power generation coil 81 disappears, and the magnet body 82 is generated by the elastic force of the second spring 86a inserted into the magnet mounting plate 84. Exit from the inside of the.

Therefore, when the tire 18 continues to rotate, the magnet body 82 continues to reciprocate with respect to the power generation coil 81. This movement causes a change in the magnetic field in the power generation coil 81, which generates an electromotive force due to electron induction, and a current flows into the wire material 77.

(Third embodiment)

Third Embodiment The operation principle is the same as that of the first embodiment of FIG. 1 described above. However, the installation of the structures of the power generation system of the present invention in the tire 18 is different from the first embodiment. Hereinafter, with reference to the accompanying drawings will be described in detail.

13 is a perspective view illustrating a third embodiment of a vehicle generator according to the present invention, and FIG. 14 is an enlarged cutaway view of a portion “C” of FIG. 13.

A plurality of cylindrical cylinders 93 are attached at regular intervals along the outer circumferential surface of the wheel 19 rim 90, and a cylindrical power generating coil 91 is attached to the cylindrical cylinder 93. At this time, the hollow portion is formed so that the rod-shaped magnet body 92 can be inserted into the inner diameter of the center of the power coil 91, and the inner diameter of the power coil 91 is inserted into the rod-shaped magnet body 92. There is a slight gap between them when they are drawn out so that no friction coefficients occur between them. The magnetic pole direction of the magnet body 92 is attached to the magnet mounting plate 94 so that one pole of the N pole and the other of the S poles are positioned in the axial direction in which the magnet body 92 is inserted into and drawn out of the power generation coil 91.

The magnet mounting plate 94 and the contact member 95 in close contact with the inner circumferential surface of the tire are connected to each other using a first spring 96a, wherein the length of the first spring 96a is the length of the power coil 91. It is set as the length of the magnet body 92 inserted into the hollow part. Connecting using the first spring 96a as described above without using a rod-shaped rod does not have a constant distance that the tire 18 contracts due to an impact received from the ground while traveling, and sometimes the tire 18 Is excessively contracted, which is to be absorbed by the first spring 96a when it is contracted more than a predetermined distance, that is, larger than the length of the magnet body 92. Therefore, the force acting to bring the contact member 95 into close contact with the inner circumferential surface of the tire 18 when the magnet body 92 is retracted larger than the length of the magnet body 92 when the magnet body 92 is inserted into the hollow of the power coil 91 is It is the elastic force of the second spring 96b.

Then, a spiral second spring 96b is inserted between the magnet mounting plate 94 and the cylinder 93 that perform the piston motion. The function of the second spring 96b serves as an elastic force that causes the tire 18 to contract and draw out the magnet body 92 inserted into the hollow portion of the power coil 91, and at the same time, the inside of the tire 18. The contact member 95 in close contact with the surface also acts as an elastic force to always be in close contact.

Therefore, the size of the elastic force of the second spring (96b), in consideration of the mass and the friction coefficient of the moving structure, should be larger than the size of the attraction force generated when the magnet body 92 inserted into the power generating coil 91 is drawn out In addition, the magnitude of the elastic force of the first spring (96a) is greater than the two forces of the sum of the elastic force of the second spring (96b) and the repulsive force generated when the magnet body 92 is inserted into the power generating coil (91). It is desirable to enlarge

In addition, the inner circumferential surface of the cylinder 93 and the outer circumferential surface of the magnet mounting plate 95 have a structure in which a friction coefficient can be minimized during sliding reciprocation, and the limit of the magnet mounting plate 94 being inserted into the cylinder 93. Make sure the depth is constant. Therefore, for this purpose, the locking jaw 300 is formed on the inner circumferential surface of the cylinder 93 so that the locking jaw 300 is formed on the inner circumferential surface of the cylinder 93 when the magnet mounting plate 94 is inserted at a predetermined depth.

In addition, the electrical wiring part of the power coil 91 may be taken out of the inner circumferential surface of the wheel and connected to the storage battery by being connected to the battery by the bushing 97a, or may be connected to the power supply of the driving part.

Operation of the power generation system of the present invention configured as described above is as follows. When the wheel is rotated and the position of the contact member 95 in close contact with the inner circumferential surface of the tire 18 is located at the point 500 in contact with the ground, at the same time, the tire 18 contracts and crushes under the load of the vehicle body. This contraction of the tire 18, the contact member 95 in close contact with the inner peripheral surface of the tire 18 is pressed, this force is transmitted to the first spring (96a), this force is again to the magnet mounting plate 94 The magnet mounting plate 94 is transmitted to the insertion motion in the cylinder (93). At the same time, the magnet body 92 attached to the magnet mounting plate 94 is inserted into the power generation coil 91.

At this time, when the wheel continues to rotate and deviates from the ground where the load of the vehicle body is concentrated, the portion of the tire 18 contracted by the internal air pressure of the tire 18 is expanded and restored, and at the same time, The force that pressed the contact member 95 in close contact disappears, and the magnet mounting plate 94 is moved to the cylinder by the elastic force of the second spring 96a inserted between the cylinder 93 and the magnet mounting plate 94. 93) withdrawal movement. At this time, the magnet body 92 attached to the magnet mounting plate 94 also exits from the inside of the power generation coil 91.

Therefore, such a power generation system is repeated when the wheel is rotated, the tire 18 is contracted at the point 500 in contact with the ground by the body load, and expands and is restored after leaving this point, such movement The silver is transmitted to the power generation system installed inside the tire 18, and the movement thus transmitted causes the magnetic body 92 to reciprocate with respect to the power generation coil 91, resulting in a change in the magnetic field. This magnetic field change causes electromotive force due to electron induction, so that current flows to the wire material 97.

As described above, according to the vehicle power generation system according to the present invention, in a rotating wheel, the tire contracts at a point where the weight of the vehicle contacts the ground due to the load applied to the wheel and the internal air pressure of the tire. By using the movement to expand and restore the power source for power generation, it can bring the effect of the effective use of energy. The electric energy generated by the generator may be used as a power source of the driving motor, or may be connected to a charging device of a power source, and may be effectively used for an electric vehicle and a hybrid car. In addition, the effective use of energy can also reduce the environmental pollution as well as economic benefits from the reduction of fuel.
