The utility model also relates to a rear door assembly provided with the vehicle body flow guide structure, and a vehicle provided with the rear door assembly. Background Art

[0002] A car spoiler is an aerodynamic component installed at the rear of a car, also known as a "car spoiler", "tail wing", etc. It can be fixed on the rear door of the car. As an important component of a car, the main function of the car deflector is to create a downward pressure due to air resistance during high-speed driving, reduce the lift at the rear of the vehicle, effectively control the downward pressure of the airflow, reduce the drag coefficient accordingly, improve the stability of the vehicle at high-speed driving and reduce fuel consumption.

[0003] At present, more and more cars are expanding the car's field of view as much as possible, that is, expanding the area of ​​the rear windshield in order to provide a good rear view of the car and improve product competitiveness. This makes the Z-direction space of the deflector smaller and smaller, resulting in the compression of the Z-direction installation surface of the car deflector. However, since the car deflector now has more and more functions, such as installing a rear camera, there is a problem that the installation surface of the compressed deflector will not be able to provide enough installation space for the rear camera. At this time, if a larger installation hole is opened on the installation surface to facilitate the installation of the camera, the deflector will be insufficient in strength, and in severe cases it will even cause the deflector to crack, which is not conducive to the structural stability of the deflector.

When a camera installation hole is opened, the strength of the wind deflector will be reduced, and in severe cases, it may cause cracking. It is difficult to ensure its own structural performance while arranging the camera conveniently, which is not conducive to improving the quality of the entire vehicle and the development of after-sales work.

At the same time, the installation holes on the second air guide plate 2 can ensure the normal use of the camera in the vehicle-mounted camera assembly, so as to achieve the effect of improving the rear field of view of the vehicle. Therefore, on the basis of ensuring sufficient structural strength, it is conducive to the installation of the vehicle-mounted camera assembly, thereby facilitating the improvement of the quality of the entire vehicle.

[0059] In addition, the detachable setting of the cover plate 3 can realize the convenient disassembly and maintenance of the vehicle-mounted camera assembly, prevent the replacement of the entire structure due to damage to the vehicle-mounted camera assembly, and help reduce costs.
