The invention provides a wind noise reduction structure and a vehicle, and relates to the technical field of vehicles. The wind noise reduction structure comprises a contraction surface and a buffer surface which face the outer side of the vehicle and are arranged in parallel in the longitudinal direction of the vehicle; the contraction surface and the buffer surface are sectioned by a horizontalsurface or a vertical surface to form section lines; the section lines of the contraction surface and the buffer surface are gradually close to the central axis of the vehicle in the extending direction from the head to the tail of the vehicle; the included angle between the section line of the contraction face and the central axis is gradually increased or equal in the extending direction from the head to the tail; and the included angle between the section line of the buffer surface and the central axis is gradually decreased or equal in the extending direction from the head to the tail of the vehicle. The wind noise reduction structure is provided with the contraction surface and the buffer surface, so that airflow firstly passes through the contraction surface and then passes through the buffer surface in the running process of the vehicle, and the airflow is buffered by the buffer surface and the contraction surface, so the wind noise of the airflow is effectively reduced.

    本发明提供了一种降风噪结构及车辆,涉及车辆技术领域。本发明的降风噪结构包括:面向所述车辆外侧在所述车辆的纵向方向上并列设置的收缩面和缓冲面,收缩面与缓冲面被水平面或垂直面剖切形成截面线,收缩面与缓冲面的截面线在车辆的头部向尾部延伸的方向上逐渐靠近车辆的中轴线,并且收缩面的截面线与中轴线的夹角由头部向尾部延伸方向上逐渐增大或相等,缓冲面的截面线与中轴线的夹角由车的头部向尾部延伸的方向上逐渐减小或相等。本发明的降风噪结构设置有收缩面和缓冲面,使得车辆在行驶过程中气流首先经过收缩面再经过缓冲面,并且气流会由缓冲面和收缩面进行缓冲,有效减小气流风噪。
