[0020] Working principle: When the urban road or the road surface is flat, the central controller starts the battery pack 17, so that the battery pack 17 supplies power to the motor 9. The output end of the motor 9 drives the first transmission shaft 2 to rotate. The first transmission shaft 2 drives the front drive wheel 3 through the first differential 4 and the half shaft, thereby driving the new energy vehicle to travel. Wind resistance is generated during driving, and the wind resistance blows the fan blades 6 to rotate. The fan blades 6 drive the generator 7 to rotate, and the generator 7 generates electricity. The generated electricity is input to the first controller 8 through the wire, and then input to the battery pack 17 through the wire through the first controller 8, so as to charge the battery pack 17 and improve the endurance of the battery pack 17. When encountering a muddy or bumpy road, the driving force of the electric drive is weak and the passability is poor. At this time, the central controller turns off the motor 9, starts the engine 10 and the drive motor 24, and the drive motor 24 drives the turbofan 22 to rotate through the rotating shaft, and draws external air into the air intake box 23. The gas entering the air intake box 23 is filtered by the filter 32, and the filtered gas enters the air guide plate 25, enters the first air guide pipe 26 through the air guide plate 25, enters the third air guide pipe 30 through the first air guide pipe 26, and enters the engine 10 through the third air guide pipe 30 to mix with the fuel, and burn to generate power. The rear drive has a strong grip, and it is fuel-driven to improve the passability of the new energy vehicle. When the car is driving, the car is inevitably bumpy and frustrated. The gas drawn in by the turbofan 22 The gas cannot completely enter the engine 10, and a part of it remains in the first air duct 26. The control valve 29 allows the remaining gas to be sucked into the box 28, and the gas entering the box 28 is pressurized to increase the density of the gas per unit volume inside the box 28, so as to facilitate the storage of the remaining gas, thereby facilitating the provision of gas to the new energy vehicle during acceleration, reducing the reaction time, and thus improving the throttle sensitivity. When the second transmission shaft 11 rotates, the second transmission shaft 11 drives the first gear 13 to rotate, the first gear 13 drives the second gear 18 to rotate, the second gear 18 drives the rotor 19 to rotate, the rotor 19 drives the coil 36 to rotate, and the coil 36 moves to cut the magnetic flux lines, thereby generating current. The generated current enters the second controller 33 through the terminal 20 and the wire, and is then input into the battery pack 17 through the wire through the second controller 33 to charge the battery pack 17, thereby improving the endurance of the battery pack 17 and increasing the practicality of the new energy vehicle.

[0021] To sum up, the device has a simple structure and novel design. It is convenient to switch the driving mode of new energy vehicles and adjust the driving mode of new energy vehicles according to different road conditions, which is beneficial to improving the passability and economy of new energy vehicles. Through structures such as fan blades and coils, it is convenient to generate current, and the generated current is input into the battery pack through wires, thereby improving the battery life of the battery pack and the practicality of new energy vehicles. Through structures such as the first air duct and the turbofan, it is convenient to store the residual gas when the new energy vehicle is bumpy and setbacks, which is convenient for use during the next acceleration, reducing the reaction time of the throttle, and improving the sensitivity of the throttle, thereby improving the driving experience, and is suitable for wide promotion.
