Air deflecting structure and automobile

Abstract

The invention relates to an air deflecting structure and an automobile. The air deflecting structure comprises an air deflecting plate, an adjusting device and a stand column. The stand column comprises a stand column body and a stand column metal plate, and both the air deflecting plate and the adjusting device are arranged on the inner side of the stand column metal plate. The stand column metal plate is provided with a strip-shaped hole allowing the air deflecting plate to pass through. The strip-shaped hole extends in the length direction of the stand column; one end of the air deflecting plate is connected with the stand column in a hinged mode, the adjusting device is connected with the air deflecting plate and used to adjust the area of the portion, outwards extending out of the stand column metal plate, of the air deflecting plate to guide airflow which passes by the air deflecting plate to bypass automobile windows behind the air deflecting plate. According to the air deflecting structure and the automobile, the air deflecting plate is arranged on the stand column of an automobile body to ensure essential functions of the automobile body, and moreover, shaping of the automobile is not affected and the airflow can be guided to flow smoothly along the automobile body. The air deflecting plate is used for guiding the direction of the airflow, so that the airflow which passes by the air deflecting plate bypasses the automobile windows behind the air deflecting plate to avoid direct impacts on the automobile windows, thus wind noise and wind vibration sound inside the automobile are reduced, and automobile comfort is enhanced.

Description

technical field [0001] The invention relates to automobile noise control, in particular to a diversion structure and an automobile. Background technique [0002] When the car is running at high speed, the friction between the airflow and the body will produce wind noise. The wind noise outside the car is transmitted to the inside of the car and becomes the main noise source in the car. And when the car window is opened, the inside of the car is connected with the outside of the car, and a cavity is formed inside the car body. At this time, the airflow acts on the car body, which will form a very annoying roar in the car, which is usually called wind vibration sound. [0003] How to control wind noise and wind vibration is a difficult problem in the field of automotive noise control. At present, there are two ways to control this kind of noise: the first is to adopt streamlined body design and streamlined partial design as much as possible; the second is to design a raised ...

Problems solved by technology

However, both methods have limitations

The first method is difficult to achieve in engineering, because the car design must meet the practicality, and it is almost impossible to design the body and parts into a complete streamlined shape. Protruding objects, such as mirrors, etc.

The second method is limited by the shape. In addition to satisfying the use function, the body also needs to meet the aesthetics of the shape. The raised mirror base will affect the beauty of the car shape, so very few cars adopt this design
