The invention discloses a high-speed elevator car turbulent flow noise reduction device which is arranged on a car top and a car bottom of an elevator car and comprises a main body and a sound absorption material. The main body extends in the left-right direction, and a mounting cavity is formed in the main body. A turbulent flow curved surface is arranged on the rear side surface of the main body; the turbulent flow curved surface is used for guiding airflow to flow towards the rear side of the elevator car when the elevator car ascends and descends. First through holes communicated with the mounting cavity are distributed in the turbulent flow curved surface; and the sound absorbing material is arranged in the mounting cavity. The invention is suitable for the high-speed elevator car. When the elevator runs at a high speed, the device can guide airflow to flow, reduce generation of aerodynamic noise, absorb part of the aerodynamic noise and improve the riding comfort of the elevator car.

    本发明公开了一种高速电梯轿厢扰流降噪装置,所述装置设置于电梯轿厢的轿顶和轿底上,包括主体和吸音材料;所述主体沿左右方向延伸,内部设有安装腔室;所述主体的后侧面上设有扰流曲面;所述扰流曲面用于在电梯轿厢升降时引导气流朝电梯轿厢的后侧流动;所述扰流曲面上分布设有与安装腔室连通的第一贯穿孔;所述吸音材料设置于安装腔室中。本发明适用于高速电梯轿厢。在电梯高速运行时,该装置能引导气流流动,减少气动噪声的产生并吸收部分气动噪声,提高轿厢的乘坐舒适性。
