Patent ID: 7960848

Claim:
An electric bike with capability of self-charging, the electric bike being fixedly supported by supporting legs so as to be operated at a stationary point, pedal assembly of the electric bike being stepped by manpower to drive a wheel and a permanent magnet motor to rotate, the electric bike including: a power-generating device coupled to the wheel by means of a transmission means or directly coupled to the wheel, the rotation of the wheel driving the power-generating device to generate a power source; a controller electrically connected to the power-generating device for receiving the power source and converting the power source into a plurality of DC power sources, and the controller including: a rectifying circuit electrically connected to the power-generating device for converting the power source generated by the power-generating device into a rectified output power source; a power supply electrically connected to the rectifying circuit for receiving the rectified output voltage and switching the rectified output power source to output a supply power source; a power switch control circuit electrically connected to the rectifying circuit for receiving the rectified output power source and supplying the second operating power source of a variable duty cycle to the damper; a microprocessor electrically connected to the power supply for receiving the supply power source outputted by the power supply and for providing a power driving signal to the power switch control circuit; and a battery charger electrically connected to the power supply for receiving the supply power source outputted by the power supply and supplying the first operating power source to the battery; a battery electrically connected to the controller for receiving and storing a first operating power source outputted by the controller; and a damper electrically connected to the controller for receiving a second operating power source outputted by the controller, thereby consuming a portion of the electricity generated by the power-generating device.
