The invention discloses an automobile rear bumper resistance reducing device, a ventilation component and an automobile, the automobile rear bumper resistance reducing device comprises a rear wheel cover, the ventilation component and an automobile tail rear bumper, the rear wheel cover is provided with a first connecting port, and the automobile tail rear bumper is provided with a second connecting port; the two ends of the ventilation component are fixedly connected with the rear wheel cover and the vehicle tail rear bumper respectively, an air channel is formed in the ventilation component, and the air channel is communicated with the first connecting port and the second connecting port; and part of airflow entering the rear wheel cover flows into the air duct from the first connecting port and then flows out from the second connecting port. The air duct is arranged between the rear wheel cover and the tail rear bumper, the aerodynamic resistance in the rear wheel cover can be reduced, flow separation on the side face of the tail rear bumper is reduced, and therefore the aerodynamic resistance of the whole vehicle is reduced. And the second connecting port is arranged at the rear bumper position of the vehicle tail corresponding to the position of the ventilation component, so that the motility of the whole vehicle can be improved, and the appearance of the vehicle is creative and attractive.

    本发明公开了汽车后保降阻装置、通风部件及车辆,其中汽车后保降阻装置,包括后轮罩、通风部件以及车尾后保,所述后轮罩上设有第一连接口,所述车尾后保设有第二连接口;所述通风部件的两端分别与所述后轮罩、所述车尾后保固定连接,且所述通风部件内设有风道,所述风道连通所述第一连接口与所述第二连接口;进入所述后轮罩的部分气流从所述第一连接口流入所述风道后从所述第二连接口流出。本发明在后轮罩与车尾后保之间设置了风道,可降低后轮罩内部的气动阻力,减少车尾后保侧面的流动分离,从而降低整车的气动阻力。对应于通风部件的位置在车尾后保位置设置第二连接口,可以增加整车的运动性,使车辆外观更具创意、更美观。
