Abstract

An electric vehicle chargeable by wind energy, enabling travel using electricity generated by wind power generation is provided. The electric vehicle includes an air inlet formed on the front of the electric vehicle to allow wind to flow in during traveling, a turbine formed at a rear end of the air inlet and rotated by wind power, a power generation unit including a rotor coupled to a rotating shaft extended from the turbine and a stator disposed in a ring shape on the outside of the rotor and generating power by rotation of the rotor, a power supply unit converting power from the power generation unit into a chargeable voltage to charge a battery and supplying a driving voltage from the battery to the electric motor, and a controller electrically connecting the battery and the electric motor controlling charging from the power generation unit to the battery.

Claims (25)

1 . An electric vehicle chargeable by wind energy, the electric vehicle comprising:

an air inlet that is formed in the front of the electric vehicle configured to travel by rotating a wheel by an electric motor to allow wind to flow in during traveling;

a turbine that is formed at a rear end of the air inlet and rotated by wind power;

a power generation unit that includes a rotor coupled to a rotating shaft extended from the turbine and a stator disposed in a ring shape on the outside of the rotor and generates power by rotation of the rotor;

a power supply unit that converts power from the power generation unit into a chargeable voltage to charge a battery and supplies a driving voltage from the battery to the electric motor;

a controller that electrically connects the battery and the electric motor through an electrical system and controls charging from the power generation unit to the battery; and

a sensor unit including a wind speed sensor formed on the front of the electric vehicle to measure wind speed during traveling, and a rain sensor to measure rainfall during a rainy season,

wherein the air inlet includes an air inlet path formed to be recessed in a center or both sides of a front lower portion of the electric vehicle, and an opening/closing port formed in the air inlet path and having an aperture structure to open/close the air inlet path, and

wherein when a measurement value above a certain level is detected by the wind speed sensor, the controller operates the opening/closing port to open the air inlet path,

wherein when rainwater inflow into the air inlet path is detected by the rain sensor, the controller operates the opening/closing port to close the air inlet path,

wherein when the rotating shaft rotates at a preset speed or higher according to a rotation speed thereof, the controller controls the rotation speed of the rotating shaft by controlling a degree of opening/closing of the opening/closing port,

wherein a semicircular brake pad is coupled to the rotating shaft, and when the rotating shaft rotates excessively, the controller controls the brake pad to reduce the rotation speed of the rotating shaft,

wherein a discharge hole is formed on a bottom surface of the air inlet path at a front or rear end of a blade of the turbine,

wherein an exhaust port communicating with the air inlet path is formed, and an auxiliary blade is formed at a rear end of the blade to form a double blade structure, and

wherein the exhaust port is provided with a damper and a return induction path to re-direct air through a pipe to an upper side surface or a lower side surface of the auxiliary blade.

2 . The electric vehicle of claim 1 , further comprising a filter net formed at the front end of the air inlet path to block the inflow of external foreign substances and a blocking film formed at the front of the filter net to open and close,

wherein the controller opens the blocking film when the electric vehicle travels at a certain speed or higher.

3 . The electric vehicle of claim 1 , wherein the turbine includes a blade coupled to the rotation shaft, a bearing guiding the rotation of the rotation shaft, and an encoder measuring a rotation number of the rotation shaft, and

the controller controls whether to charge the battery from the power generation unit according to the rotation number by the encoder.

4 . The electric vehicle of claim 3 , wherein the blade is formed in two stages to be respectively disposed at front and rear ends of the rotating shaft.

5 . The electric vehicle of claim 3 , wherein a nacelle is formed to protrude at a front center of the blade.

6 . The electric vehicle of claim 1 , wherein the air inlet path is formed with a tapered cross-sectional structure whose diameter narrows toward the turbine.

7 . The electric vehicle of claim 6 , wherein an exhaust port communicating with the air inlet path is formed at the rear of the electric vehicle, and a size of the exhaust port is formed to be relatively larger than a size of the air inlet path.

8 . The electric vehicle of claim 7 , wherein the exhaust port is formed to extend to be inclined at a certain angle upward from the ground.

9 . The electric vehicle of claim 1 , wherein solar cell modules are arranged on an upper portion of a body of the electric vehicle.
