DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel-driven power generator, and more particularly, to a wheel-driven power generator driven by rotation of driving wheels of an automobile.

[0002]

2. Description of the Related Art As an emergency or private power generator, a wheel drive power generator that generates power by using the rotation of driving wheels of an automobile has been proposed. Such a conventional wheel drive power generator is disclosed in, for example, Japanese Utility Model Laid-Open No. 58-50571.
Is described in Japanese Patent Application Publication No. This wheel drive power generator includes a wheel bearing rotating member in which an idle roller and a drive roller are arranged in parallel, and an AC generator, wherein the AC generator is coaxial with the axis of the drive roller, and It is arranged outside the roller.

In this wheel drive power generator, when the vehicle wheel is mounted on the idle roller and the drive roller and rotated, the idle roller and the drive roller are rotated by the rotation of the vehicle wheel, and the shaft of the drive roller is rotated. The rotation is transmitted to the rotating shaft of the alternator coaxially connected to the outside of the drive roller. As a result, the rotating shaft of the AC generator is driven to rotate, and power generation is performed by the AC generator.

[0004]

However, in such a conventional wheel drive power generator, an AC generator is used.
While making it coaxial with the drive roller rotated by the wheels,
Since it is located outside the drive roller, the wheel drive generator becomes large as a whole, and in some cases, it becomes difficult to install the AC generator while maintaining coaxiality with the drive roller. There was a problem of becoming.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a small-sized wheel drive generator having a small number of failures by incorporating a generator coil and a permanent magnet in a roller driven to rotate. It is assumed that.

[0006]

The gist of the present invention resides in a pair of parallel rollers rotatably supported on fixed shafts, respectively, which are rotated by driving wheels of an automobile mounted thereon. A pair of rollers to be moved are provided, and at least one of a coil or a permanent magnet constituting an armature is attached to an inner surface of the one of the rollers, and the fixed shaft corresponding to the roller is provided with the coil or the permanent magnet. The other is a wheel drive power generator in which the coil and the permanent magnet are attached to face each other, whereby the problem can be solved.

[0007] In this case, for example, the coil and the permanent magnet are arranged so as to face each other in the axial direction of the roller and the fixed shaft, respectively, so that the plurality of coils can be switched to series connection or parallel connection. Can be configured. As described above, the coil may be mounted on the fixed shaft, and the permanent magnet may be mounted on the inner surface of the roller.On the contrary, the permanent magnet may be mounted on the fixed shaft, and the coil may be mounted on the inner surface of the roller. The former, which does not require a slip ring or the like, for extracting the current induced in the above, is more preferable.

In order to use the wheel drive power generator as a DC power supply, a rectifier circuit for rectifying a current induced in the coil may be provided on a base supporting the fixed shaft. As described above, in the wheel drive power generator, one or both of a pair of parallel rollers rotatably supported on a fixed shaft and the corresponding fixed shaft, the coil and the coil. The permanent magnets are disposed so as to face each other. When only one of the permanent magnets is disposed, the other roller is an idle roller. In the above,
Although the roller to be an idle roller has been described only as being rotatably mounted on a fixed shaft, the present invention provides a rotatable rotating shaft in place of the fixed shaft, and the idle roller should be used for this. This naturally includes the one for fixing the roller. Since the two are substantially the same and need not be specially described, only the idle roller that is rotatably mounted on the fixed shaft will be described below, and further description thereof will be omitted.

[0009]

The present invention is constructed as described above.
It can be used as follows. A driving wheel of an automobile is mounted on the pair of rollers, and an engine of the automobile is operated to rotationally drive the driving wheels. The operation of the driving wheels drives the rollers to rotate.

However, as described above, since the coil and the permanent magnet are provided so as to face at least one of the rollers and the corresponding fixed shaft, an electromotive force is generated in the coil with the rotation of the roller. Then, the induced current can be taken out. At this time, as described above, when a plurality of pairs of coils and permanent magnets are arranged, by connecting the coils in series or in parallel, it is possible to meet a demand such as a high voltage small current or a low voltage large current. Can be. When a rectifier circuit is provided on the fixed shaft, the power generator can be used directly as a DC power supply.

As described above, in the wheel-driven power generator of the present invention, since the generator is formed inside the device, the generator is disposed outside the device, and the generator is provided by the driving wheels of the automobile. Since there is no need to transmit the rotational force, the size of the device can be reduced as a whole, and the failure rate can be reduced.
