Abstract

(57) [Summary] [Purpose] Install a solar panel on a two-wheeled vehicle so that it does not interfere with driving. [Structure] A large number of single-crystal silicon solar cells 4 are attached to one side of a disc-shaped wheel 3 of a two-wheeled vehicle. A slip ring 10 for sending electric power generated by the solar cell 4 to the storage battery 8 and the electric motor 5 is provided on the shaft portion of the wheel 2.
The output shaft of the reduction gearbox 6 connected to the electric motor 5 is connected to the pedal shaft by a transmission chain 7.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a two-wheeled vehicle that runs on a solar cell.

[0002]

[Prior Art]

 A conventional solar car is a four-wheeled vehicle with a cabin, and many solar cells are mounted on the cabin. When driving a two-wheeled vehicle with solar cells, there is no cabin, so how to arrange the solar cell panels becomes a problem.

[0003]

[Problems to be solved by the device]

 This invention provides a two-wheeled vehicle driven by a solar cell in which a solar cell panel is arranged so as not to interfere with traveling.

[0004]

[Means for Solving the Problems]

 In the solar cell driven two-wheeled vehicle of this invention, the solar cell panel is attached to the side surface of the wheel (either one side or both sides may be used), and electric power is sent to the vehicle body side through a slip ring provided on the wheel shaft portion. It was done like this.

[0005]

【Example】

 FIG. 1 is a side view of a solar cell driven motorcycle. The vehicle body 1 has the same structure as a conventional bicycle, but the wheel 3 of the wheel 2 is not a spoke wheel but a disc wheel as shown in the cross section in FIG. A large number of single crystal silicon type solar cells 4 are attached to one surface of the disk wheel.

An electric motor 5 and a reduction gearbox 6 connected to the electric motor are mounted on the vehicle body 1, and an output shaft of the gearbox is connected to a pedal shaft and a transmission chain 7. A worm gear may be used instead of the transmission chain 7. In addition, reference numeral 8 is a storage battery (for example, nickel-zinc battery), and reference numeral 9 is a drive unit of the electric motor.

A slip ring 10 for transmitting electric power generated by the solar cell 4 to the storage battery 8 and the electric motor 5 is provided on the shaft portion of the wheel 2.

This two-wheeled vehicle parks the solar cell panel 4 (wheel side surface) toward the sun in a sunny place. In this way, the energy obtained from the solar cell is stored in the storage battery 8 while the bicycle is parked.

[0012] Folding solar panels (not shown) are loaded in this two-wheeled vehicle. When power shortage is expected, take out the solar cell panel and place it next to the parked two-wheeled vehicle. Then, make sure that the storage battery stores sufficient power.

When traveling, the electric motor 5 is driven by the electric power stored in the storage battery 8. If power is obtained from the solar cells when the vehicle is on a sunny day, it can be used at the same time.

When sunlight cannot be obtained while the bicycle is parked, the storage battery is charged from a commercial power source. When running, when the power is insufficient, you can step on the pedal like a conventional bicycle.

[0012]

[Effect of the device]

 The solar cell driven two-wheeled vehicle of the present invention is one in which the solar cell is attached to the side surface of the wheel, and electric power is taken out to the vehicle body side through the slip ring provided on the axle of the wheel. Therefore, a large light receiving area can be secured, and since the solar cell does not project outside the vehicle body, it does not interfere with traveling and the wind pressure area does not increase.
