The present invention relates to a vehicle power generation system that generates energy by recovering energy, and more particularly, 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 increased. When applied to a tire, the part contacting the ground is crushed and contracted. As the wheel continues to rotate and leaves this point, that is, the point where the load is concentrated, the retracted tire portion is inflated and restored by the internal air pressure of the tire. As described above, the present invention relates to a power generation system that generates electricity by using energy that contracts and expands generated in a tire while driving a vehicle as a power source required for power generation.

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. However, these methods have a limitation in that continuous and stable development is difficult because energy can be recovered only when braking or only when a shock occurs due to shaking of the vehicle body.

The present invention has been made in view of the above, by using the contraction and expansion kinetic energy generated in the tire by the load of the vehicle body and the internal air pressure of the tire in the driving state of the wheel as a power source for power generation of the vehicle Its purpose is to continuously generate electricity without driving external energy while driving.

(First embodiment)

A first preferred embodiment 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 wheels, FIG. 2 is a side view of FIG. 1, FIG. 3 is an operating state diagram of FIG. 1, and FIG. 4 is "I-" of FIG. 1. 5 is a cross-sectional view taken along the line "I", FIG. 5 is a cross-sectional view taken along the line "II-II" of FIG. 2, FIG. 6 is a side view showing another embodiment of the power generation coil part "A" of FIG. "B" section is an enlarged perspective view.

In the power generation system of the present invention, the fastening nut 10a of the base 10 is connected to the bolt of the axle 940 to which the wheel wheel 910 is fastened and fastened to the side of the wheel 910. Therefore, the base 10 fastened to the wheel shaft 940 becomes a structure that rotates with the wheel. On the surface of the base 10, a plurality of power coils 11 are radially arranged and attached to the origin. The power coil 11 has a coil 11a line wound in one spiral to have a cylindrical shape, and a rod-shaped magnet body 12 can be inserted into and drawn out from the cylinder of the power coil 11. Form a hollow part. At this time, when the magnet body 12 is inserted into and withdrawn from the hollow portion of the power coil 11, the inner circumferential surface of the hollow portion and the outer circumferential surface of the magnet body 12 are such that the coefficient of friction does not occur. In addition, a cylinder 13 corresponding to each of the power generation coils 11 is installed in the base 10, and a rod shaft 14 for reciprocating in each of the cylinders 13 is inserted. 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. And in the rod shaft 14, one end portion is in close contact with the outer peripheral surface of the tire 900 is coupled to the close contact member 15 for transmitting the contraction and expansion movement of the tire 900 generated in the driving state of the wheel, The magnet body 12 is provided in the other end part. In addition, a spring 16 is provided on the rod shaft 14 between the magnet body 12 and the cylinder 13, and the contact member 15 is always provided on the outer circumferential surface of the tire 900 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 the N pole and the other end is the S pole, and the magnetic field is changed by reciprocating the insertion and withdrawal in the axial direction to the hollow portion formed in the cylindrical power generating 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 connected to a charging device or connected to other electronic parts such as drive motors of electric vehicles and hybrid vehicles.

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

Vehicle wheels are used by fitting the tire 900 to the wheel 910 and charging the air therein. The reason why the tire 900 is used to pressurize air is because the riding comfort is superior to that of using the rigid wheels. In this way, the wheel used to pressurize the air inside the tire 900, the portion 950 of the tire 900 in contact with the ground due to the weight of the vehicle is crushed, the contraction degree is not constant but about 20 to 35mm The degree is crushed and contracted. The constricted portion 950 has a cycle in which the wheel is rotated and then expanded and restored by the internal air pressure of the tire 900 when the wheel is out of the point.

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.

At this time, when the wheel rotates as the vehicle travels, the base 10 coupled to the wheel shaft also rotates together. The load of the vehicle body is concentrated at the point 950 where the tire 900 abuts the ground, and the tire 900 contracts by crushing the portion 950 abutting the ground. At the same time, the contact member 15 positioned at the point where the tire 900 is contracted is also contracted together by the distance that the tire 900 is contracted by the load of the vehicle body.

The contraction of the contact member 15 contracts and moves the rod shaft 14 connected thereto in the axial direction to transfer the rod-shaped magnet body 12 attached to the rod shaft 14 into the hollow portion of the power generation coil 11. Insert it.

At this time, since the rotation of the tire 900 continues to progress, the close contact member 15 that is in close contact with the outer peripheral surface of the tire also rotates together. Therefore, when the tire 900 continues to rotate and leaves the point 950 that contacts the ground, the portion that has been contracted by the air pressure inside the tire 900 expands. At the same time, the inflating tire 900 also expands the contact member 15 in close contact with the outer circumferential surface of the tire 900.

The expansion of the close contact member 15, the axial axis 14 connected to the expansion and movement in the axial direction, and the magnet body 12 attached to the spigot axis 14 also expands and moves in the axial direction together. That is, due to the contraction of the tire 900, the magnet body 12 inserted into the hollow portion of the power generation coil 11 exits with the expansion of the tire 900.

The spring 16 inserted into the rod shaft 14 between the cylinder 13 and the magnet body 12 acts on the rod shaft 14 by applying an elastic force in the direction of the power generation coil 11 to the outer circumferential surface of the tire 900. The close contact member 15 located in the always to be in close contact with the outer peripheral surface of the tire (900). At this time, the centrifugal force generated by the rotation of the tire 900 acts as a force to separate the axle shaft 14 attached to the base 10 and the close contact member 15 connected thereto. Therefore, it is preferable that the spring 16 uses a spring 16 having a larger elastic force than the magnitude of the centrifugal force generated by the rotation of the wheel generated from the rod shaft 14 and the contact member 15.

In addition, the contact member 15, when the contact member 15 coupled to closely contact the outer circumferential surface of the tire 900 protrudes more than the outer circumferential surface of the tire 900, traveling by the impact of the ground during the rotation of the tire 900 It can cause vibration and rolling resistance of the wheels. Therefore, the contact member 15 may be inserted into a groove formed to prevent slippage on the outer circumferential surface of the tire 900 such that the surface of the contact member 15 does not protrude more than the outer circumferential surface of the tire 900.

In the vehicle power generation system of the present invention configured as described above, when the wheel is driven by driving of the vehicle, the tire 900 has a cycle of contraction and expansion movement, and the cycle movement is transmitted to the rod shaft 14 to the rod shaft. The magnetic body 12 attached to the 14 moves axially in the axial direction with respect to the power generating coil 11, causing a magnetic field change in the power generating coil 11, which causes electromotive force to be generated by the electromagnetic petroleum. Current flows to (17). At this time, the female slim ring 18 to which the wire material 17 is connected is also coupled to the female slim ring 18a to which the wire material 17 is connected to send a current to a rechargeable battery or a driving unit.

The effect of the present invention is to use the power source to generate electricity by using the contraction and expansion kinetic energy generated from the tire 900 while driving the vehicle to produce electricity without additional energy input from the outside, the generated electricity is a charger It can be used by charging it or by connecting to other electric parts such as driving motors of electric vehicles and hybrid vehicles.
In addition, when the adhesive member 15 contacting the ground in contact with the outer surface of the tire 900 is rotated and combined with the contact member 15 protruding from the outer circumferential surface of the tire 900, It can also provide additional functions to suppress slippage.

(Example of transformation)

FIG. 6 is a side view illustrating a modified implementation of the power generation coil unit of FIG. 1, and the operating principle is the same as that of the first embodiment of FIG. 1.

As shown in FIG. 1, the cylinder 13, the rod shaft 14, the close contact member 15, the spring 16, and the like coupled to the rod shaft are installed in the same manner as the base 10. The power coil 111 installed on the base 10 and the magnet body 112 attached to the rod shaft 14 are different.

An example of the modification will now be described with reference to FIGS. 6 and 7.

In FIG. 6, only one power generation coil 111 is installed on the center of the origin of the base 10, and a plurality of magnet bodies 12 act in correspondence with the power generation coil 111. The coil 111a line is wound in a unidirectional spiral in the power generation coil 111. At this time, the power coil 111 is formed in a cylindrical shape as in the first embodiment, and the shape is similar to that of the base 10. Four rod shafts 14 are installed. At this time, the axial direction of the coil wound around the power generation coil 111 is the same as the axis direction of the rod shaft 14, and the magnetic pole direction of the magnet body 12 is also the same as the axis center direction of the rod shaft 14. On the other hand, the example of Figure 7 is installed so that the axial center direction of the coil 111a wound on the power generation coil 111 to be perpendicular to the axial center direction of the rod shaft 14, the magnet attached to the rod shaft 14 The magnetic pole direction of the sieve 112 is attached so that it may become orthogonal to the axial center direction of the moving rod shaft 14.

In this structure, since a plurality of magnet body 112 attached to the rod shaft 14 acts on one power coil 111 built in the center of the origin of the base 10, the magnetic field as compared to FIG. The relative speeds of the overconductors are high in FIGS. 6 and 7.

Because, when the wheel is rotated once, FIG. 1 shows one magnetic field change in each reciprocating motion of each magnet body 12 with respect to each power coil 11, but FIG. 6 and FIG. This is because the three magnet bodies 112 concentrate on only one power coil 111 located at the center. That is, FIG. 1 shows that the power coil 11 and the magnet body 12 correspond to 1: 1, but FIGS. 6 and 7 show a plurality of magnet bodies 112 with respect to one power coil 111. Will act in response.

6 and 7, the number of magnetic field changes generated in the power generation coil 111 is generated by the number of magnet bodies 112 acting on the power generation coil 111, which is a magnetic field. As the relative speed of the overconductor increases, the electromotive force increases, resulting in greater power generation efficiency than FIG. 1 of the first embodiment.

(2nd embodiment)

As shown in FIG. 8, the second embodiment of the present invention includes the base 20, the power generation coil 21, the magnet body 22, the cylinder 23, and the spring 26. Same as the embodiment, except that the fastening portion of the contact member 15 fastened to the distal end of the rod shaft 14 of the first embodiment is left as it is, and removes only the contact member in close contact with the outer peripheral surface of the tire 900, the spring ( 16) The site where it is installed is different.

Referring to FIG. 8 and FIG. 9, which shows a cross-sectional view taken along line III-III of FIG. 8, the contraction process of the rod shaft 14 of the first embodiment described above is the same, but it is expanded. The power source is different. That is, the expansion of the rod shaft 24 in the second embodiment is caused by the elastic force of the spring 26 provided on the rod shaft 24.

At this time, the position where the spring 26 is installed is inserted into the rod shaft 24 between the cylinder 23 and the fixing ring 25 to be installed. On the other hand, when the rod shaft 24 is fully inflated, it is preferable that the end of the rod shaft 24 is equal to the outer diameter of the outer diameter of the unretracted tire 900. Because, when the rod shaft 24 is inflated, if the distal end point protrudes a little bit more than the outside diameter of the outer diameter of the tire 900, an impact with the ground is generated during the rotation of the wheel, and the rolling resistance of the wheel is caused. to be.

In addition, by coupling a roll wheel formed of an elastic material such as rubber to the end of the rod shaft 24 in contact with the ground during the rotation of the wheel, noise and vibration that may occur when the ground shaft and the rod shaft 24 contact It will be a preferred way to offset such.

Operations and effects of the present invention according to the second embodiment are the same as the first embodiment described above, and have been described in the first embodiment, and thus will be omitted.

(Third Embodiment)

In the third embodiment, the tire 900 of the portion 950 in contact with the ground is crushed and contracted by the vehicle body load, and the side surface of the tire 900 swells and protrudes. The part is contracted and restored again. As described above, a cycle movement in which both side surfaces of the tire 900 protrude and contract by the vehicle body load is used as a power source for power generation, and the operation principle is the same as that of the first embodiment. . Hereinafter, a third embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

10 is a perspective view illustrating a third embodiment of a vehicle generator according to the present invention, and FIG. 11 is a side view of FIG. 10.

In the configuration of the third embodiment of the present invention, the base 30 is fastened to the side of the wheel 910 by connecting to the bolt of the axle fastening the wheel wheel 910. The base 30 is attached to the plurality of lever connecting member 34a disposed radially from the origin, and the lever 34 is installed on the lever connecting member 34a. At this time, one end of the lever 34 is in close contact with the side portion of the tire 900, and the other end is provided with a magnet body (32).
In addition, a cylindrical power generation coil 31 is installed on the base 30 so that the magnet body 32 acts as a reciprocating motion to generate a current. The coil 31a is wound around the coil 11a in a unidirectional spiral, and a hollow part is formed at the center of the coil 31 so that a rod-shaped magnet body 32 can be inserted and drawn out. The part has a gap such that a friction coefficient does not occur with each other during the insertion and withdrawal of the rod-shaped magnet body 32. At this time, the magnetic pole direction 32 of the magnet body 32 attached to the lever 34 has the N pole in one direction and the S pole in the other direction in the reciprocating direction.
Then, a spring 36 is provided between the side portion of the lever 34 and the base 30 at the position where the magnet body 32 is attached. The spring 36 applies elastic force to the lever 34 so that one end point of the lever 34 always comes into close contact with the side surface of the tire 900, and the magnet body 32 moves to generate power. After being inserted into the coil 31, the magnet body 32 also acts as an elastic force for exiting again. In this case, the elastic force of the spring 36 is weaker than the force from which the tire 900 protrudes, and the elastic force of the spring 36 is greater than that of the attraction force acting when the magnet body 32 inserted into the power generation coil 31 exits.
Looking at the operating state of the third embodiment of the present invention configured as described above are as follows.
During driving of the vehicle, the portion of the tire 900 in contact with the ground is crushed and contracted by the vehicle body load, and the side portion swells and protrudes. ) Into the hollow portion of the power coil (31). At this time, if the wheel continues to rotate, the projecting portion is restored and contracted again, and at the same time the spring 36 installed between the lever 34 and the base 30 pushes the lever 34, the power coil 31 The magnet body 32, which was inserted in, exits. As described above, the magnet body 32 attached to the lever 34 generates a change in the magnetic field in the winding coil by the action of the insertion and withdrawal motion of the power generation coil 31, which generates an electromotive force by electromagnetic induction. Current flows through the material 37.
Since the effects according to the present invention have been described above in the first embodiment, they will be omitted.

(Example of transformation)

12 is the same as the operation principle of FIG. The reason for the configuration different from that of FIG. 10 is to increase the relative speed of the magnetic field and the conductor as in FIG. Hereinafter, with reference to the accompanying drawings will be described in detail.

12 is a perspective view illustrating an example of a modification of the power generation coil part 31 of FIG. 10, FIG. 13 is a cross-sectional view taken along the line “V” of FIG. 12, and FIG. 14 is a view along the line “V-V” of FIG. 12. Cutting cross section.

Only one power generation coil 131 is laid at the center of the origin of the base 30, and one magnet body 132 acts on the power generation coil 131.

A plurality of lever connecting members 34a are radially attached to the base 30, and levers 34 are installed on the lever connecting members 34a. One end portion of the lever 34 is in close contact with the side surface of the tire 900, and the other end portion is in close contact with the end surface of the magnet mounting plate 139 arranged in the center. A rod-shaped magnet body 132 is attached to the cross section opposite to the magnet mounting plate 139.

A cylindrical power generating coil 131 is installed at the center of the origin of the base 30, and at this time, a hollow portion is formed at the center of the power generating coil 131, and a rod-shaped magnet body 132 is inserted into the hollow portion. It is designed to be drawn out, and at this time, the gap is so large that the coefficient of friction does not occur during insertion and withdrawal.

In addition, a second spring 136 is installed inside the cylinder 133 between the magnet mounting plate 139 and the power generation coil 131 to elastically pull out the magnet body 132 inserted into the power generation coil 131. The spring 34 is installed on the lever 34 between the lever connecting member 34a and the magnet mounting plate 139 in the lever 34 so that an elastic force for pushing the lever 34 is applied. The end of the lever 34 in contact with the side of the tire 900 is always in close contact. At this time, it is preferable that the magnitude of the two forces that combine the elastic forces of the second spring 136 and the spring 36 to be smaller than the force protruding the side portion of the tire 900 by the vehicle body load.

The operation of FIG. 12 configured as described above is the same as that of FIG. 10 of the third embodiment, and thus the operation and effect thereof are omitted.

(Example 4)

The fourth embodiment also has the same operation principle as that of the first embodiment of FIG. However, it is different from the first embodiment to install the components of the power generation system of the present invention inside the tire 900. Hereinafter, with reference to the accompanying drawings will be described in detail.

15 is a perspective view illustrating a fourth embodiment of a vehicle generator according to the present invention, and FIG. 16 is a cross-sectional view taken along the line “IV-IV” of FIG. 15.

A plurality of cylindrical cylinders 43 are attached at regular intervals along the outer circumferential surface of the rim 920, and a cylindrical power generation coil 41 is installed inside the cylindrical cylinder 43. At this time, the hollow portion is formed so that the rod-shaped magnet body 42 can be inserted into the inner diameter of the center of the power generation coil 41, and the inner diameter of the power coil 41 is inserted into the rod-shaped magnet body 42. When pulling out, leave a small gap so that the friction coefficient does not occur with each other. The magnetic pole direction of the magnet body 42 is attached to the magnet mounting plate 49 so that one pole of the N pole and one pole of the S pole are positioned in the axial direction in which the magnet body 42 is inserted into and drawn out of the power generation coil 41.

The magnet mounting plate 49 and the contact member 45 in close contact with the inner circumferential surface of the tire are connected to each other by using a first spring 46, wherein the length of the first spring 46 is the length of the power coil 41. It is preferable to set it as the length of the magnet body 42 inserted into a hollow part. Connecting using the first spring 46 as described above, without using a rod-shaped rod, the distance that the tire 900 contracts due to the impact received from the ground while traveling is not constant, sometimes the tire 900 Is excessively contracted, which is to be absorbed by the first spring 46 when it is contracted more than a predetermined distance, that is, greater than the length of the magnet body 42. Therefore, the force acting to bring the contact member 45 into close contact with the inner circumferential surface of the tire 900 when the magnet body 42 is retracted larger than the length of the magnet body 42 when the magnet body 42 is inserted into the hollow of the power generation coil 41 is It is the elastic force of the second spring 146. The second spring 146 is inserted between the magnet mounting plate 49 and the cylinder 43.

The function of the second spring 146 acts as an elastic force for the tire 900 to contract and draw out the magnet body 42 inserted into the hollow portion of the power coil 41, and at the same time, the inside of the tire 900. The contact member 45 in close contact with the surface also acts as an elastic force to always be in close contact.

Therefore, the magnitude of the elastic force of the second spring 146, considering the mass and the friction coefficient of the moving structure, and the attraction force due to the electromagnetic force generated when the magnet body 42 inserted into the power generating coil 41 is drawn out It should be larger than the size, and the magnitude of the elastic force of the first spring 46, the sum of the elastic force of the second spring 146 and the repulsive force generated when the magnet body 42 is inserted into the power generating coil 41. It is desirable to make it bigger than force

In addition, the inner circumferential surface of the cylinder 43 and the outer circumferential surface of the magnet mounting plate 49 have a structure in which a friction coefficient can be minimized during sliding reciprocation, and the limit of the magnet mounting plate 49 being inserted into the cylinder 43. Make sure the depth is constant. Therefore, for this purpose, the locking jaw 43a is formed on the inner circumferential surface of the cylinder 43 so that the locking jaw 43a is formed on the inner circumferential surface of the cylinder 43 when the magnet mounting plate 49 is inserted at a predetermined depth.

In addition, the electrical wiring of the power generation coil 41 may be connected to the rechargeable battery by being taken out of the inner circumferential surface of the wheel and connected to the rechargeable battery, or may be connected to the power supply of the driving unit.

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 45 in close contact with the inner circumferential surface of the tire 900 is located at the point 990 which is in contact with the ground, at the same time, the tire 900 is contracted and collapsed by the load of the vehicle body. The contraction of the tire 900 is to press the contact member 45 in close contact with the inner peripheral surface of the tire 900, this force is transmitted to the first spring 46, the force is transferred to the magnet mounting plate 49 The magnet mounting plate 49 is transferred to the insertion movement in the cylinder 43. At the same time, the magnet body 42 attached to the magnet mounting plate 49 is inserted into the power generation coil 41.

At this time, when the wheel continues to rotate and deviates from the ground where the load of the vehicle body is concentrated, a portion of the tire 900 contracted by the internal air pressure of the tire 900 is expanded and restored, and at the same time, the wheel 900 is in close contact with the inner circumferential surface of the tire 900. The force that pressed the contact member 45 is lost, the magnet mounting plate 49 is the cylinder 43 by the elastic force of the second spring 146 inserted between the cylinder 43 and the magnet mounting plate 49. Withdrawal movement). At this time, the magnet body 42 attached to the magnet mounting plate 49 also exits from the inside of the power generation coil 41.

The power generation system of the present invention receives the movement to restore the contraction and expansion generated in the tire 900 generated during driving, the magnetic body 42 acts a reciprocating motion with respect to the power coil 41 to change the magnetic field Bring it. This magnetic field change causes electromotive force due to electromagnetic induction, so that current flows to the wire material 47.
