The invention relates to an airflow introduction structure for actively reducing vehicle wind vibration noise. One end of a guide pipe is a gas inlet, and the other end of the guide pipe is a gas outlet; the airflow generator is connected with the guide pipe and drives gas to enter the guide pipe from the gas inlet and to be discharged from the gas outlet so as to form airflow; the airflow direction regulator is arranged at the gas outlet and regulates the airflow direction of the airflow discharged from the gas outlet; the controller is connected with the airflow generator and the airflow direction regulator, controls the airflow generator to work according to the received airflow direction and the airflow velocity corresponding to the vehicle speed interval where the running speed of the vehicle is located so as to generate airflow with the airflow velocity, and controls the airflow direction regulator to work so as to generate airflow with the airflow velocity. Therefore, the airflow is discharged towards the outer side of the window of the vehicle in the airflow direction. An air flow is actively introduced through the structure to generate a Karman vortex street phenomenon with a natural air flow outside a vehicle window, wind vibration noise is weakened, the air permeability is met, meanwhile, wind noise is reduced, and the driving experience feeling is improved.

    本申请涉及一种用于主动降低车辆风振噪音的气流引入结构,导管一端为气体入口,另一端为气体出口;气流发生器与导管相连,并驱使气体自气体入口进入导管,并从气体出口排出,以形成气流;气流方向调节器设于气体出口,并调节从气体出口排出的气流的气流流向;控制器与气流发生器和气流方向调节器相连接,并根据接收车辆的行驶速度所在的车速区间所对应的气流流向及气流流速,控制气流发生器工作,以产生具有该气流流速的气流,以及控制气流方向调节器工作,以使气流以该气流流向朝车辆的窗口外侧排出。通过该结构主动引入一股气流,以与车辆窗口外的自然气流产生卡门涡街现象,削弱风振噪音,在满足透气性的同时降低风噪,提高驾乘体验感。
