[0004] Technical solution: To solve the above technical problems, a wind power generation device for use on an electric car of the present invention is installed at the front end of the car, and includes a fixed bracket and a generator. A first bearing and a second bearing are installed on the fixed bracket, and a rotating shaft is installed on the first bearing and the second bearing.

One end of the rotating shaft is connected to the generator through a transmission device, and an air inlet is provided on the windward surface of the fixed bracket; when the car is driving, the wind direction goes against the driving direction of the car, and the airflow flows to the air inlet, which increases the wind force at the air inlet and increases the torque of the impeller. The impeller drives the transmission shaft to rotate, and the transmission shaft drives the generator to rotate through the transmission device to generate electricity, and the electricity is charged into the battery.

[0005] Preferably, the fixed bracket includes side mounting plates, a bottom mounting plate, a top mounting plate and a rear mounting plate on both sides, and the side mounting plates, the bottom mounting plate, the top mounting plate and the rear mounting plate form a fixed bracket, and the front end of the fixed bracket forms an air inlet.

[0006] Preferably, the air inlet of the fixed bracket is provided with an inclined baffle.

[0008] Preferably, the fixed bracket is provided with two fixed brackets stacked, the fixed bracket includes a first fixed bracket and a second fixed bracket, the power generation device includes a first generator and a second generator, the first fixed bracket is provided with a first bearing and a second bearing, the first rotating shaft is provided with a first bearing and a second bearing, both ends of the first rotating shaft are provided with a first impeller fixing piece, the first impeller is provided with a first impeller fixing piece, one end of the first rotating shaft is connected to the first generator through a first transmission device, an air inlet is provided on the first fixed bracket, and a first baffle is hinged on the first fixed bracket; a third bearing and a fourth bearing are provided on the second fixed bracket, the second rotating shaft is provided with a second bearing and a fourth bearing, both ends of the second rotating shaft are provided with a second impeller fixing piece, the second impeller is provided with a second impeller fixing piece, one end of the second rotating shaft is connected to the second generator through a second transmission device, and a second baffle is hinged on the second fixed bracket; a periscope is provided on the top of the first fixed bracket.

[0009] Preferably, a spring is installed between the baffle and the bottom mounting plate.

[0010] The present invention is mainly to increase the driving mileage of current unmanned electric vehicles, and convert part of the fixed wind resistance into electricity, which is specifically achieved by the following method. A wind turbine generator dedicated to unmanned vehicles is installed in front of the car and consists of a generator fixing frame, a transmission shaft, a bearing, an impeller, an impeller fixing frame, a gasket, a generator, a windshield, etc. Specifically, it is a transmission shaft, with impeller fixing frames on both sides. Six impellers are fixed in an annular manner on the impeller fixing frame and are synchronously linked to the transmission shaft. There is a bearing on each side of the transmission shaft, and there are gaskets on both sides of the bearing. The bearing is embedded in the generator fixing frame. The windshield is at the same height as the transmission shaft and is obliquely connected to the two generator fixing frames. On one side of the generator fixing frame, a generator is fixed, and the generator is driven by the transmission shaft belt link.

[0011] The working process of the present invention is as follows: when the car is driving, the wind is in the reverse direction of the car's driving direction. Due to the effect of the wind shield, the airflow flows to the air inlet, increasing the wind force at the air inlet and increasing the torque of the impeller. The impeller drives the transmission shaft to rotate, and the transmission shaft drives the generator to rotate through the belt to generate electricity, and the electricity is charged into the battery. Since the wind shield is placed obliquely, the adverse wind passes through the wind shield and enters the air inlet, which is equivalent to increasing the area of ​​the air inlet.

[0012] Depending on the model of the vehicle, the wind deflector is about half the height of the wind turbine and is placed below the air inlet at a 45-degree angle.

[0013] When a car is driving, its resistance mainly comes from wind resistance. The higher the speed, the greater the wind resistance. Since the wind turbine is equipped with an impeller, the rotation of the impeller effectively converts the fixed wind resistance into rolling wind resistance, greatly reducing the resistance of the car. Due to the effect of the inclined wind shield, the headwind is sent into the air inlet, reducing the resistance by about 0.293.

[0014] If the car is 1.5 meters high, the height of the air inlet is about 0.75 meters, and the height of the windshield is about 0.75 meters. Since the windshield is placed at an angle of 45 degrees, 0.75 meters X 0.707 equals 0.4395, which is equivalent to the height of the windshield changing from 0.75 meters to 0.4395 meters. Then the air inlet is about 1.5 meters minus 0.4395 meters, which equals 1.0605 meters. The air inlet is increased from 50% to 70%. The increase in the air inlet effectively increases the headwind volume, increases the torque of the impeller, and enhances the power generation of the generator.

[0015] Beneficial effects: The wind power generation device used in the electric vehicle of the present invention outputs electric power to the battery through the electronic circuit stabilizer. The battery is in a state of discharging and storing electricity, and the driving distance of the electric vehicle can be increased by more than double. BRIEF DESCRIPTION OF THE DRAWINGS
