Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses electricity generated by a power generation mechanism incorporated in a diff cap of an automobile to light a lamp attached to a wheel while the vehicle is running, and the portion of the wheel from another vehicle becomes a wheel of light. The present invention relates to a shiny wheel for automobiles for the purpose of preventing accidents by improving visibility.

[0002]

2. Description of the Related Art If a lamp is attached to the wheel of an automobile and the lamp is turned on while the vehicle is running, it looks like a wheel of light from another vehicle.
Although it is clear that the visibility is improved, it was difficult to safely and semipermanently maintain the effect from low speed to high speed without changing the structure of the existing automobile tire or wheel.

[0003]

An object of the present invention is to improve the visibility from other vehicles by installing a power generation mechanism and a lamp without changing the structure of an existing automobile tire or wheel and safely turning on the lamp from low speed to high speed. It is what

[0004]

In order to solve the above-mentioned problems, the present invention utilizes the fact that the inside of the diff cap 1 for a rear wheel of a vehicle with a diff cap 1 is hollow, and a large gear 2 is provided on the inner central axis. The concentric spindle 3 is rotatably supported, and the spindle 3
The fixed weight 4 is hung at one end, and the generator motor 5 is fixed at a position where the small gear 7 integrated with the motor shaft 6 meshes with the large gear 2 of the main shaft 3, and the lead wire 8 of the generator motor 5 is attached to the outer periphery of the differential cap 13. It is connected to the lamp 9 and turned on.

On the other hand, as a safety device, a rotation stopper 10 is provided on one shoulder portion of the fixed weight 4, and an eccentric shaft 11 is attached at a position offset from the position directly above the main spindle 3 in the opposite direction to the rotation stopper 10. Rotation stop 10 around the eccentric shaft 11
The movable weight 12 is rotatable by an angle limited to.

Electricity obtained by these power generating mechanisms can be attached to lamps 9 at various places on the wheels by extending the lead wires 8.

[0007]

Since the present invention has the above-mentioned means, when the differential cap 1 rotates together with the wheel, the fixed weight 4 attached to the internal main shaft 3 is always positioned below due to gravity, and therefore the main shaft 3 integrated with it. The large gear 2 also remains stationary without being affected by the rotation of the wheels. On the other hand, the generator motor 5
As the differential cap 1 rotates, the small gear 7 rotates around the outer periphery of the large gear 2 while engaging with each other, so that the speed increasing action proportional to the gear ratio can be obtained, and the power generating motor 5 can generate power even at a low speed.

In terms of safety, when the fixed weight 4 is lifted up due to over-rotation of the wheels or a strong impact from the road surface during traveling, the wheels are rotated by the rotation of the wheels and generate vibrations. May interfere with driving. As a means for preventing this, in addition to the fixed weight 4, the movable weight 12 is attached to the eccentric shaft 11 above the fixed weight 4 so as to be rotatable about the axis. However, the movable weight 12 normally serves as a weight for turning the generator motor 5 by the rotation stop 10 on the right or left side of the fixed weight 4, but both weights are repelled by excessive rotation of the wheels or a strong impact from the road surface. , When turning around the main axis 3,
The movable weight 12 moves close to 180 degrees from the rotation stopper 10 due to the centrifugal force and automatically balances with the fixed weight 4, so that vibration does not occur. Rotation stop 10 of fixed weight 4 is movable weight 12
Is attached to the right side when the body rotates rightward and to the left side when the body rotates leftward so that it becomes a weight for rotating the generator motor 5. On the other hand, the eccentric shaft 11 is displaced from directly above the main shaft 3 in the opposite direction with respect to the rotation stop 10. This is a measure for the movable weight 12 to instantaneously separate from the rotation stop 10 when functioning as a safety device.

Electricity generated by the power generation mechanism incorporated in the diff cap 1 is extended by extending the lead wire 8.
If it is attached to the diff cap outer peripheral portion 13, the wheel nut 14, the valve 15, the rim 16 or the like at one or a plurality of places through the attachments 17, it looks like a large or small light ring when traveling.
