[Problems to be solved by the invention]
It is an object of the present invention to provide a power generation device that generates power by using a change in the shape of a tire that occurs when a vehicle travels and the inside of the tire.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is arranged inside the tire so as to move in a direction substantially perpendicular to the rotation axis of the tire, and in a position interlocked with deformation of the inner side surface of the tire. Fields in which the protrusions of the permanent magnets and the permanent magnet posts arranged at the position supporting the protrusions are wound on the iron cores placed on both sides of the permanent magnet posts in conjunction with the movement of the protrusions. It consists of two magnetic poles in the configuration of the winding, and when the vehicle is in contact with the tire and the ground point when the vehicle is running, the inner surface of the tire pushes up the first convex part with the change in the shape of the tire caused by the vehicle load, Proposed is an in-tire power generator, wherein the permanent magnet supports generate power by moving up and down between both magnetic poles in conjunction with the movement of the convex portion.
[0005]
According to the in-tire power generation device according to the above configuration, the tire attached to the vehicle is distorted in the shape of the tire at the contact point between the tire and the ground due to the vehicle load. Is deformed toward the direction of the rotation axis of the tire, and the convex portion is pushed toward the direction of the rotation axis of the tire. That is, in the tire, the convex portion is pushed by the inner surface of the tire and moves in a direction substantially orthogonal to the rotation axis of the tire, whereby the support column supporting the convex portion is In conjunction with the movement, the magnetic field is fluctuated by moving up and down between the magnetic poles arranged on both side surfaces of the support column to generate power. More specifically, there are N poles and S poles at both ends of the support of the permanent magnet that receives the projections. If the upper end in contact with the projections of the support is N poles, the lower end of the support is S poles. It becomes. The two poles of the structure of the field winding with windings on the iron core disposed on both sides of the permanent magnet support are N poles on the convex side, on the opposite side, on the center part side of the tire The end is configured as the S pole. According to the above configuration, the S pole of the permanent magnet column and the N pole of the field winding arranged on the side surface of the column attract each other, so that the mutual position is maintained. In addition, as the inner surface of the tire is deformed, the convex portion is pushed to the inside of the tire, so that the support of the permanent magnet that supports the convex portion exceeds the stable position where the magnetic poles bounce, and further, the center of the tire After that, the release from the force received from the inner surface of the tire and the S pole on the tire center side of both poles consisting of the S pole and the field winding at the lower end of the permanent magnet column And the repulsive force of each other move toward the original position, that is, in the direction opposite to the center of the tire. The generated current can be guided out of the tire through the coil of the field winding by the vertical movement of the support of the permanent magnet supporting the convex portion.
[0006]
Further, in the in-tire power generation device of the present invention, in the tire, the convex portion according to claim 1 and the support of the permanent magnet that supports the convex portion in conjunction with the movement of the convex portion are both side surfaces of the post of the permanent magnet. The magnetic field is made up and down by moving up and down the magnetic field consisting of the field windings wound on the iron core arranged on the iron core, that is, the permanent magnet column moves up and down between the two magnetic poles. 2. A protrusion of the permanent magnet for supporting the protrusion, comprising an opening on the periphery, which is in contact with the inner surface of the tire and can move in conjunction with a change in the shape of the inner surface of the tire And the tire-shaped iron ring which can enclose both the magnetic poles of the both sides | surfaces of a support | pillar was arrange | positioned.
[0007]
According to the above configuration, a tire-shaped iron ring having a size that can be mounted inside a tire that is substantially the same type as the tire, and the convex portion according to claim 1 and a permanent magnet that supports the convex portion inside the tire-shaped iron. And the magnetic poles on both side surfaces of the column can be included, and an opening is provided on the peripheral edge of the iron ring so that the convex portion contacts the inner surface of the tire, thereby changing the shape of the tire. Accordingly, the inner side surface of the tire can come into contact with the convex portion. The permanent magnet column supporting the projections moves in the vertical direction between the magnetic poles arranged on both side surfaces of the column in conjunction with the movement of the projections, thereby changing the magnetic field and generating power.
[0014]
As an explanation of terms, in the present invention, the tire may be any tire as long as it is used for a vehicle. Specifically, for example, tires attached to automobiles, trucks, motorcycles, motorbikes, bicycles, and the like can be used.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0016]
FIG. 1 is a plan view showing a schematic configuration in which the in-tire power generator in the first embodiment of the present invention is installed inside the tire, and FIG. 2 shows a state in which two sets of in-tire power generators are installed in the tire. It is a cross-sectional perspective view. In the figure, the in-tire power generator is installed inside a tire 5, 1 is a convex portion, and is supported by a support 2, and both magnetic poles 3 are fixed on the foil 4 so as to be located on both side surfaces of the support 2. ing.
[0017]
Since the convex portion 1 comes into contact with the inner surface of the tire 5 as the shape of the tire 5 changes, the material and shape of the convex portion 1 are devised so as not to be spherical or damage the inner surface of the tire 5. preferable. Moreover, the support | pillar 2 is supported by the force which opposes with both the magnetic poles 3, and the support | pillar 2 is supporting the convex part 1 so that the convex part 1 may be located in the place where it is easy to receive the change of the shape of the tire 5. .
[0018]
In the in-tire power generator in the first embodiment, power generation is performed as follows. That is, when the outer side surface of the tire 5 on the surface where the convex portion 1 is located inside the tire 5 is in contact with the ground, the shape of the tire 5 changes due to the vehicle load, so the inner surface of the tire 5 on the surface where the convex portion 1 is located. Is deformed in the direction of the rotation axis of the tire 5 and comes into contact with the convex portion 1, and thus a force for pushing the convex portion 1 in the direction of the rotational axis of the tire 5 is generated. The struts 2 that support the convex portion 1 are linked with the movement of the convex portion 1 to change the magnetic field by performing an upper limit motion between the magnetic poles 3 disposed on both side surfaces of the strut 2, thereby generating power.
