A wind power generation device applied to pure electric vehicles

Abstract

The invention discloses a wind power generation device applied to a pure electric vehicle. The wind power generation device comprises a wind collecting cover, a wind wheel, a bearing, a coupling, a generator and a charging control circuit, wherein the wind collecting cover is arranged in a front cabin of the vehicle; the wind wheel is arranged in the wind collecting cover; a wind outlet is formed in the tail end of the wind collecting cover; the rear part of the wind outlet is connected with an air flow dredging pipeline; the wind wheel comprises a power shaft and five wing-type blades; the power shaft is connected with the generator through the coupling; the generator is connected with the charging control circuit through a wire; the generator and the charging control circuit are fixedly arranged on a front cabin frame; electric energy generated by working of the generator passes through the charging control circuit and then is stored in a battery. According to the wind power generation device, the wind resistance existing in the running process of the vehicle all the time can be effectively reduced, the energy can be partially recovered, and the endurance mileage of the pure electric vehicle can be increased to a certain extent.

Description

technical field [0001] The invention relates to an energy recovery device for a pure electric vehicle, in particular to a wind power generation device for reducing the driving wind resistance of the vehicle and recovering energy to improve the cruising range of the pure electric vehicle. Background technique [0002] At present, with the continuous increase of car ownership, the energy crisis has attracted more and more attention from the society. How to realize the energy recovery of pure electric vehicles without changing the shape of the existing car body has become a technical problem to be solved urgently by automobile manufacturers and related practitioners. [0003] The power battery is the only power source for pure electric vehicles, and the capacity of the battery pack has a crucial impact on the cruising range of electric vehicles. Wind resistance always exists when the car is running, and when the car is running at high speed, the energy consumption of wind resi...

AI Technical Summary

Problems solved by technology

A kind of vehicle wind power generation device disclosed in Chinese patent literature [Application No.: 201020649114.6 Publication No.: CN 201941609 U] is characterized in that the housing, fan and generator of the wind power generator are installed on the roof of the vehicle, and the wind power generator is used to drive the car. The headwind drives the wind wheel to rotate to generate electricity. The disadvantage of this design is that it greatly increases the windward area of ​​the car and increases the driving resistance of the car.

The disadvantage of this design is that the wind wheel is placed in the middle of the front cabin, occupying the position of the cooling water tank of the air conditioning system

The air outlet is opened on the front hatch, and rainwater can easily enter the front cabin, which brings safety hazards

In addition, the chassis of the car has an air outlet, which affects the stability of high-speed driving
