The invention discloses a device for reducing the wind vibration noise of a rear side window of an automobile. The device comprises a cover plate which is disposed on the outer side surface of an automobile body vertical column of the automobile, one side of the cover plate is connected with the automobile body vertical column, and the other side of the cover plate can rotate relative to the automobile body vertical column; a driving mechanism is connected with lifting glass of a rear side window of an automobile, the lifting glass is connected with the automobile body stand column through a lifting sliding rail, the reset mechanism is connected with the cover plate and the automobile body stand column, and when the lifting glass rises, the reset mechanism can drive the other side of the cover plate to rotate inwards. The outer surface of the cover plate is flush with the outer surface of the vehicle body stand column. According to the invention, the direction of airflow can be guided,so that the airflow does not directly act on the rear side window of the automobile, the wind noise and the wind vibration sound in the automobile are reduced, the comfort of the automobile is improved, the air resistance when the rear side window of the automobile is opened is reduced, an additional control system is not needed, the cost is low, and the structure is simple.
本发明公开了一种降低汽车后侧窗风振噪声的装置,其包括:盖板,设置在汽车的车身立柱的外侧面上,所述盖板的一侧与所述车身立柱相链接,所述盖板的另一侧能够相对于所述车身立柱进行旋转;驱动机构,与汽车后侧窗的升降玻璃相连接,所述升降玻璃通过升降滑轨与所述车身立柱相连接,复位机构,与所述盖板和车身立柱相连接,当所述升降玻璃上升时,所述复位机构能够驱动所述盖板的另一侧向内旋转,使所述盖板的外表面与所述车身立柱外表面相齐平。本发明能引导气流的方向,使得气流不直接作用到汽车后侧窗上,其降低风噪声和车内风振声,提高了汽车的舒适性,降低开汽车后侧窗时的空气阻力,且无需额外控制系统,其成本低、结构简单。
