In order to describe the charging device and method proposed by the present invention more clearly, the preferred embodiments of the present invention will be described in detail below with reference to the drawings.

Referring to Figure 1, in one embodiment, a charging device suitable for electric motorcycles includes a first rotating component 10, a power generation component 11, an AC to DC conversion circuit 12, a voltage reduction circuit 13, a capacitor module 14, and an electric controller 15 , electric motor 16, second rotating component 17, manual control device 18.

The first rotating component 10, with reference to Figure 2, in one embodiment, includes the front wheel of an electric motorcycle (not shown), an outer ring gear 101, five planetary gears 102, and a central gear 103, which can amplify the input rotational speed. Then output after multiple times. The radii of the five planetary gears 102 and the sun gear 103 are smaller than that of the outer ring gear 101 . The central gear is arranged at the center of the outer ring gear 101 and meshes with the five planetary gears 102; the five planetary gears 102 mesh with the outer ring gear 101. When the front wheel of the electric motorcycle rotates, the outer ring gear 101 rotates at the same speed. The outer ring gear 101 drives five planetary gears 102, and the planetary gears 102 drive the sun gear 103. The rotation speed of the central gear 102 may be several times that of the outer ring gear 101, such as 4 to 8 times. The rotation speed of the outer ring gear 101 is equal to the rotation speed of the front wheel of the electric motorcycle. In this way, the front wheel of the electric motorcycle can be rotated at a low speed, or even the front wheel can only rotate back and forth in place, and the outer ring gear 101 can also rotate back and forth in place. The charging device can generate sufficient charging voltage to charge the capacitor. The module 14 is charged and then drives the electric motor 16 .

In one embodiment, the outer ring gear 101, the five planetary gears 102, and the center gear 103 are all helical gears.

The first rotating component 10 drives the power generation component 11 through the central gear 103, and in one embodiment, can generate three-phase alternating current. The three-phase alternating current is converted into direct current through an AC-to-DC conversion circuit 12, such as a bridge rectifier circuit, and the direct current has a conversion voltage. Because the center gear 103 rotates several times higher than the outer ring gear 101 (or relative to the front wheel of the electric motorcycle), the AC power generated by the generator assembly 11 is rectified into DC power and the converted voltage output is easily It is higher than the charging voltage required for constant voltage charging of the capacitor module 14, so the voltage needs to be lowered subsequently.

After receiving the input direct current, the voltage reducing circuit 13 lowers the conversion voltage, and then outputs the charging voltage required for constant voltage charging of the capacitor module 14 . In one embodiment, the voltage reducing circuit 13 includes a backflow protection circuit (not shown). The backflow protection circuit may include a capacitor and is disposed at the input end of the voltage reducing circuit 13 .

In one embodiment, the capacitor module 14 includes a plurality of supercapacitors connected in series and a power management circuit, which can be charged at a constant voltage. The charged capacitor module can be used as a power source to provide power. Supercapacitors may be electric double layer capacitors, which require a shorter charging time than rechargeable batteries.

In one embodiment, the electric controller 15 can convert the direct current output by the capacitor module 14 into a three-phase sinusoidal alternating current, and then use the three-phase sinusoidal alternating current to drive the electric motor 16 . In one embodiment, the capacitor module 14 uses direct current to drive the electric motor 16 through the electric controller 15 .

The electric motor 16 may drive a second rotating component 17, such as the rear wheel of an electric motorcycle. The rotation of the rear wheel of the electric motorcycle can drive the front wheel to rotate; when the front wheel rotates, the outer gear rotates; the rotation speed of the front wheel is amplified and used to drive the power generation component 11, and then charges the capacitor module 14 to store electricity and continuously provide electricity. to the electric motor.

The manual control device 18, in one embodiment, includes a manual starting device, a manual braking device, and a manual accelerating device of the electric motorcycle. The manual control device 18 can control the starting, braking, and acceleration of the electric motor 16 through the electric controller 15, and further controls the starting, braking, and acceleration of the electric motorcycle.

Steps 20 and 21, in one embodiment, the first rotating component includes a front wheel of an electric motorcycle, an outer ring gear is set inside the front wheel, a sun gear is set at the center of the outer ring gear, and five planetary gears are set between the outer ring gear and the sun gear. . When the front wheel is rotated, the outer ring gear rotates with the front wheel, and both have the same first speed. The outer ring gear meshes with and drives the planetary gear, and the planetary gear meshes with and drives the sun gear. The second rotational speed finally output by the central gear of the first rotating component is several times the first rotational speed, such as 4 to 8 times. Multiple planetary gears can slow down the wear caused by meshing between gears. In one embodiment, rotating the first rotating component includes rotating the front wheel back and forth in place.

Step 22: Use the second rotation speed to drive the power generation component to generate electricity to generate three-phase alternating current.

Step 24: Convert the three-phase alternating current into direct current. In one embodiment, the voltage of the converted direct current is reduced.

Step 25: Charge the capacitor module with the reduced voltage. In one embodiment, the capacitor module includes a plurality of supercapacitors connected in series and a power management circuit, which can be charged at a constant voltage. The charged capacitor module can be used as a power source to provide power. Supercapacitors may be electric double layer capacitors, which require a shorter charging time than rechargeable batteries.

Step 26: The capacitor module provides power to drive the electric motor, and the electric motor drives the second rotating component. In one embodiment, the second rotating component is a rear wheel of the electric motorcycle.

Step 27: In one embodiment, the rotation of the rear wheel of the electric motorcycle drives the rotation of the front wheel. After the front wheel rotation speed is amplified, it drives the power generation component to generate electricity to charge the capacitor module. The capacitor module can store electricity and continuously supply power.
