when the wind resistance of the vehicle needs to be reduced, firstly selecting the projection length of the coordinate point M to the coordinate point N in the X-axis direction to be 353mm; the projection length of the coordinate point M to the coordinate point N in the Z-axis direction is 55mm, one end, close to the installation part 13, of the flow guide part 12 is flush with the tail end of the ceiling of the vehicle, the tail is installed at the tail part of the ceiling of the vehicle through the installation part 13, and then the included angle between the tangent line of the coordinate point M on the air supply plane B and the X-axis direction is 14.9 degrees; finally, installing flow guide shells 7 on two sides of the empennage body 1 and fixing two sides of a rear windshield;
when the rear windshield glass needs to be cleaned, the rotating mechanism 5 is started, the rotating mechanism 5 is utilized to drive the windscreen wiper 6 to move out of the placing groove, and the outer surface of the rear windshield glass reciprocates to clean the rear windshield glass;
when the condition of the rear end of the vehicle needs to be observed, the camera 4 is started. Thus, the use process of the wind resistance-reducing type tail wing is completed.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications derived therefrom are intended to be within the scope of the invention.
