An air amplifier for electric vehicles

Abstract

The invention relates to an air amplifier for electric vehicles. The air amplifier comprises a guide hood, a backflow liner tube, diversion branch pipes, a diversion fan, spray ports, angle sensors, an air speed sensor, a diversion hood and a control circuit. The guide hood covers the backflow liner tube; the diversion hood is connected with the front end face of the guide hood; the sidewall of the guide hood is communicated with the tail end of the diversion branch pipe via a guide port; the front end face of one diversion branch pipe is communicated with the diversion fan; the front end of at least one another diversion branch pipe is communicated with the spray port; the spray ports are distributed evenly in the inner surface of the backflow liner tube around the axis of the backflow liner tube; each turnplate mechanism is provided with at least one angle sensor. The air amplifier has the advantages that the requirement on installation and use of different types of electric vehiclescan be effectively met; natural air flow can be effectively increased to carry out pressurizing and accelerating.

technical field [0001] The invention relates to an electric vehicle equipment, in particular to an air amplifier for the electric vehicle. Background technique [0002] At present, in the electric vehicle equipment, in order to improve the power performance and endurance of the electric vehicle during operation and achieve the purpose of reducing wind noise, etc., a wind power generation system is installed in the electric vehicle, and the air flowing through the surface of the electric vehicle is used to generate electricity. Air flow rectification achieves the purpose of reducing wind resistance, but it is found during operation that because the current wind power equipment used for electric vehicles needs to maintain a continuous and stable wind speed and wind pressure during operation, the wind speed and wind pressure flowing through the vehicle surface are stable when the vehicle is running.

[0002] At present, in the electric vehicle equipment, in order to improve the power performance and endurance of the electric vehicle during operation and achieve the purpose of reducing wind noise, etc., a wind power generation system is installed in the electric vehicle, and the air flowing through the surface of the electric vehicle is used to generate electricity. Air flow rectification achieves the purpose of reducing wind resistance, but it is found during operation that because the current wind power equipment used for electric vehicles needs to maintain a continuous and stable wind speed and wind pressure during operation, the wind speed and wind pressure flowing through the vehicle surface are stable when the vehicle is running. The performance is relatively poor, so at present it is mainly to add air amplifiers to wind power generation equipment to increase the constant wind speed and wind pressure to meet the needs of power generation, but the air amplifiers currently used are often used in other industries. Therefore, on the one hand The size and structure of the air amplifier are relatively large, which cannot effectively meet the requirements for the use of electric vehicles with different structures. At the same time, it is easy to cause changes in the overall aerodynamic layout of the electric vehicle equipment, which seriously affects the smooth development of the design and use of electric vehicles. On the one hand, the air amplifiers currently used in electric vehicles cannot flexibly adjust the structure according to the needs of vehicle operation, resulting in relatively poor air amplifiers’ ability to pressurize, speed up and guide airflow, and cannot effectively meet the needs of electric vehicles. needs
