1. By adding a series of structural components such as bellows, generator main body, fan blades, transmission shaft, and air inlet and outlet, when the device is in use, the device is installed at the engine position under the front hood of the pure electric vehicle, and Expose the air inlet of the bellows to the outside of the front face, and convert the electrical energy output from the generator to the electrical energy conversion on the control equipment and a series of required equipment. The user controls the state of the excitation generator through the internal control equipment of the vehicle during the driving process of the pure electric vehicle. If the driving speed of the car is greater than 60 mph, the control device controls the excitation generator to generate electricity. Otherwise, it is not generating power when the speed is less than 60 mph. The fan is idling to reduce wind resistance during driving. At this time, the forward wind of the car is poured into the bellows from the air inlet and passes through the fan. The blade rotates to discharge the wind, and the wind box is discharged to the outside world to reduce wind resistance. When the drive shaft rotates, it transmits power to the output shaft of the generator main body that is fixedly connected to the drive shaft, so that the main body of the generator works to convert electrical energy, and then the outside Under the combined action of the electric energy conversion auxiliary equipment, the electric energy is transferred to the battery for storage, and provides partial electric power support for the car. Since the auxiliary equipment is used for the idling of the wind wheel when the vehicle is running at the bottom speed, the exhaust air does not generate wind resistance, so the purpose of the device structure is not. Under the action of increasing the total wind resistance of the car, it collects and utilizes part of the forward wind and converts it into electrical energy to provide partial power support for the car. We have a very reasonable installation position for the wind turbine generator set. It does not increase the wind resistance structure of the original car design, and does not increase the wind resistance of the car. The total area does not violate the principle of the law of conservation of energy, and has a very large use value, which is worthy of promotion.
