Abstract

The present invention provides a light emitting wheel, characterized in that, a light emitting device is attached to the light emitting wheel, the light emitting device is composed of a bulb, a first elastomer, a second elastomer, a power supply, a conducting wire and a protective cover. When a vehicle is started, the on-off state of the bulb can be controlled by a switch, the bulb will move towards a direction away from the center of the wheel hub, and a ring of light will be formed due to the phenomenon of persistence of vision. The higher the speed of the vehicle is, the larger the diameter of the ring of light is, so that the vehicle is driven with rich dynamic effect.

First claim

The invention claimed is:

1. A light emitting wheel, characterized in that, a light emitting device is attached to the light emitting wheel, the light emitting device is composed of a bulb, a first elastomer, a second elastomer, a power supply, a conducting wire and a protective cover, and: one end of the first elastomer is connected to the bulb, and the other end of the first elastomer is connected to a first point on the outer side of a wheel; one end of the second elastomer is connected to the bulb, and the other end of the second elastomer is connected to a second point on the outer side of the wheel; the conducting wire forms a circuit between the bulb and the power supply; the protective cover is transparent and is covered above the bulb, the first elastomer, the second elastomer, the power supply and the conducting wire; and the distance from the first point on the outer side of the wheel to the center of the wheel is different from that from the second point on the outer side of the wheel to the center of the wheel;
preferably, the light emitting device further comprises a remote switch which controls the electric connection between the power supply and the bulb; or
preferably, the difference between the distance from the first point on the outer side of the wheel to the center of the wheel and that from the second point on the outer side of the wheel to the center of the wheel is greater than 5 cm; more preferably, the difference is 5-14 cm; and yet more preferably, the difference is 7-10 cm.

2. The light emitting wheel according to claim 1 , characterized in that 1-9 groups of the light emitting devices are attached to the light emitting wheel; preferably, 5-7 groups of the light emitting devices are attached.

3. The light emitting wheel according to claim 1 , characterized in that, the first point on the outer side of the wheel is located at one end of a wheel spoke away from the center of the wheel, and the second point on the outer side of the wheel is located at one end of a wheel spoke close to the center of the wheel.

4. The light emitting wheel according to claim 1 , characterized in that, the first elastomer and the second elastomer are springs; preferably, the elastomers are light springs.

5. The light emitting wheel according to claim 1 , characterized in that, the elastic coefficient of the first elastomer is k 1 , the elastic coefficient of the second elastomer is k 2 , the mass of the bulb is m, and the numerical value of (k 1 +k 2 )/m is 2.0-20.0×10 3 N/(m×kg); preferably, the numerical value of (k 1 +k 2 )/m is 4.5-12×10 3 N/(m×kg); more preferably, the numerical value of (k 1 +k 2 )/m is 5-10×10 3 N/(m×kg).

6. The light emitting wheel according to claim 1 , characterized in that, the material of the protective cover is transparent polypropylene or polyester; preferably, the protective cover is fixed on the hub of the wheel in an adhesion manner.

7. The light emitting wheel according to claim 1 , characterized in that, the power supply is a lithium battery mounted with a remote control device.

8. The light emitting wheel according to claim 1 , characterized in that, the conducting wire is integrated in the first elastomer and/or the second elastomer.

9. The light emitting wheel according to claim 1 , characterized in that, the distance from the second point on the outer side of the wheel to the center of the wheel is 13-21 cm and is preferably 15-20 cm, for example, 16-18 cm.

10. The light emitting wheel according to claim 1 , characterized in that, at a static state, the distance from the bulb to the center of the wheel is 3-9 cm and is preferably 4-7 cm, for example, 5 cm.
