Embodiment 1

[0039] The permanent magnet single-phase alternator is equipped with a 14×14cm gear on the rear wheel of the electric bicycle, that is, the hub of the electric bicycle is connected with the generator gear with a chain. When the speed of the electric moped reaches 10 km / h, the generator sends out AC 150V voltage, and the speed reaches 15-45 km / h to maintain AC 220V50Hz. The converter automatically transfers to various devices for work, such as charging, lighting, speakers, motors, etc. DC voltage ranges can be set: 36V, 48V, 60V, 96V, which can work quickly, realize spontaneous self-driving, and improve the problem that the battery of the electric moped can no longer drive after driving less than 80 kilometers.

[0040] When the driving speed of the electric moped reaches 15 to 50 kilometers per hour, the vehicle exchange device can work normally at 180V-240V50Hz, and the permanent magnet single-phase alternator can normally play the role of each electronic component when drivin...

Embodiment 2

[0042] The inventor uses the electric bicycle which he trial-manufactured on the road, because the single-phase alternator of the electric bicycle can fully utilize the inertial motion potential energy transformation in the driving process. When the speed of the vehicle reaches 15 km / h, it can use the inertial potential energy to generate AC 150V voltage. When the speed reaches 20-40 km / h, the power generated by inertia is higher than that required by the original motor. The electronic converter automatically switches to DC 36V, 48V, 60V, 96V (Note: power 380W, 500W, 900W, 1000W) is converted from the potential energy of the speed inertial motion of the electric moped to energy during driving, and the electronic converter has more than double the use of the brushless motor. When an electric vehicle is driving on the streets, it cannot generate electricity, because it cannot generate electricity by itself at a speed of less than 10 kilometers per hour. That is, it can be used b...

Abstract

The invention provides a self charging walking electrically power assisted bicycle, which comprises a bicycle frame, bicycle wheels, bicycle shafts, an electric motor and a storage battery, wherein the electric motor is arranged on the bicycle shafts, and the storage battery provides motive power for the electric motor. The invention is characterized in that a set of chain wheels and gears is arranged on a fly wheel of the back bicycle shaft and drives a permanent magnetic AC power generator to generate power through the transmission to a chain wheel or a gear arranged on a shaft of the permanent magnetic AC power generator via a chain or the gear, an output winding of the permanent magnetic AC power generator is connected with a detector, an intelligent controller, a power supply processing circuit and a motor control circuit, the detector is connected with an electric motor control circuit, the electric motor and the storage battery, and an output lead of the storage battery is connected with the electric motor. When the electric bicycle is in normal operation, an internal-combustion AC power generator set assembled in the electric bicycle provides the motive power for the electric bicycle. When the speed reaches 20 km per hour, the power generation amount of a self power generator also has excessive electric energy to be charged to the storage battery.

Description

technical field [0001] The invention relates to an electric vehicle, especially an electric bicycle which can convert the kinetic energy of walking into electric energy and store it, and effectively use it to provide power to the motor to enable it to continue walking. Background technique [0002] At present, electric mopeds have become a means of transportation to replace motorcycles or bicycles in cities or towns, mainly because electric mopeds are labor-saving in use, easy to operate, do not burn oil or gas, and do not emit harmful gases that pollute the environment. Motorcycles with oil are cheaper, have a certain speed than pedal bicycles, and are suitable for family and personal short-distance use, but their biggest drawback is that the battery capacity is small, the power consumption is fast, and it needs to be charged frequently. When the battery is out of power, it can only be stepped on by manpower, which is laborious and brings a lot of troubles to users. In orde...
