Background

At present, with the development of electric automobiles, the endurance capacity of the electric automobiles is greatly improved, but compared with fuel automobiles, the electric automobiles are puzzled by the aspects of endurance mileage, electric quantity supplement and the like. Although the existing electric vehicle regenerative braking energy recovery system can provide a certain cruising ability for the running electric vehicle, the system is limited, and can only supplement a certain amount of electric energy for the electric vehicle when the vehicle decelerates and brakes, but the system has the maximum electric energy consumption when the vehicle accelerates, normally runs and runs at a high speed, and cannot provide electric energy and supplement electric energy when the vehicle needs to supplement electric energy, and compared with the acceleration, the system normally runs, and runs at a high speed, and the operation of deceleration and braking is less, so that the working efficiency of the system is lower, and the cruising ability of the running electric vehicle is increased is lower.

It is known that a vehicle can generate strong wind power in the driving process, the higher the speed of the vehicle is, the larger the generated wind power is, and the electric vehicle is no exception. Although the wind power generated during driving is very large, the wind power is very dispersed and cannot be effectively utilized, no effective system device can collect and utilize the strong and dispersed wind power generated by the electric automobile during driving, the waste is wasted, and no effective system device can collect and intensively utilize the dispersed wind power to convert the dispersed wind power into electric energy to supplement the electric quantity for the driving electric automobile, so that the cruising ability of the electric automobile is improved.

In order to overcome the defects of the prior art, the invention aims to provide a new energy electric vehicle wind energy conversion, recovery and centralized utilization power generation system, which converts the dispersed wind power generated during the running of the electric vehicle into mechanical energy through each energy conversion group, converts the mechanical energy into hydraulic energy, finally uniformly converges the hydraulic energy converted by each energy conversion group into a hydraulic oil confluence device, and uniformly outputs the hydraulic oil confluence device to drive a power generation device to generate power, thereby realizing the recovery and centralized utilization of the dispersed wind power, realizing the supplement of electric quantity for the running electric vehicle, and further increasing the cruising ability of the electric vehicle.

In order to achieve the purpose, the invention adopts the technical scheme that:

Every hidden inner space all sets up: an independent energy conversion group (S), and the size of the drum-type wind power fan (1) in the energy conversion group (S) is matched with the hidden inner space.
