The invention discloses a wind resistance reducing flow guide plate containing flow guide grooves, a vehicle bottom device and a vehicle. The wind resistance reducing flow guide plate comprises a flow guide plate body, the front end of the flow guide plate body is connected with the front portion of the vehicle, and the rear end of the flow guide plate body is connected with the rear portion of the vehicle; a receding hole is formed in the flow guide plate body, a protrusion at the bottom of a vehicle can stretch out of the receding hole, a flow guide groove is formed in front of the receding hole and gradually inclines downwards in the direction from front to back, and a lower edge step is arranged behind the receding hole and gradually inclines downwards in the direction from front to back. The flow guide groove can guide air flow in front of the protrusion at the bottom of the vehicle to the lower edge step. Protruding objects at the bottom of the vehicle can be avoided, airflow in front of the protruding objects at the bottom of the vehicle can be guided and dredged, and wind resistance is reduced.

    本发明公开的一种含导流槽的降风阻导流板、车辆底部装置及车辆,包括导流板本体,导流板本体的前端与车辆前部连接,导流板本体的后端与车辆后部连接;在导流板本体上设置避让孔,车辆底部凸出物能够从避让孔中伸出,在避让孔前方设置导流槽,导流槽沿从前向后的方向逐渐向下倾斜,在避让孔后方设置下沿台阶,下沿台阶沿从前向后的方向逐渐向下倾斜,导流槽能够将车辆底部凸出物前方的气流导流至下沿台阶处。既能对车辆底部凸出物进行避让,又能对车辆底部凸出物前方的气流进行导流及疏导,降低风阻。
