The dust and resistance reducing device comprises a chassis assembly, a rear wheel cover, a concentration sensor, a controller, a first flow guide part and a second flow guide part, the vertical height of the lower end of the rear wheel cover is lower than the vertical height of the bottom of the chassis assembly, and the first flow guide part is rotatably arranged at the end, close to the vehicle tail, of the chassis assembly; the second flow guide piece is arranged at the lower end, close to the tail, of the rear wheel cover in a liftable mode. The controller controls the movable end of the first flow guide part to rotate by a preset angle so as to reduce the rolling height of airflow at the tail of the chassis assembly, and when the dust concentration measured by the concentration sensor is larger than or equal to a preset concentration value, the controller controls the second flow guide part to move by a preset distance in the direction away from the chassis assembly. And dust in a rear wheel cover area is prevented from entering a vehicle tail along with airflow. According to the dust falling and resistance reducing device and the vehicle, the problem of dust accumulation of the tail camera and the back window is solved.
本申请涉及一种降尘减阻装置及车辆,降尘减阻装置包括底盘组件、后轮罩、浓度感应器、控制器、第一导流件和第二导流件,后轮罩下端部竖直高度低于底盘组件底竖直高度,第一导流件可转动地设置于底盘组件靠近车尾的一端,第二导流件可升降地设置于后轮罩靠近车尾的下端部。控制器控制第一导流件的活动端转动预设角度,以降低底盘组件尾部气流的上卷高度,当浓度感应器测得粉尘浓度大于或等于预设浓度值时,控制器控制第二导流件朝向远离底盘组件的方向移动预设距离,以阻挡后轮罩区域的粉尘随气流进入车尾。本申请提供的降尘减阻装置及车辆,解决了尾部摄像头和背窗积灰的问题。
