Stand column flow-guide structure and automobile

Abstract

The invention relates to a stand column flow-guide structure and an automobile. The stand column flow-guide structure comprises a stand column, an air supply system, an air curtain adjusting assembly and a control system, wherein a long-strip-shaped air jet nozzle is formed in the outer wall of the stand column and extends in the length direction of the stand column; the air supply system communicates with the air jet nozzle and used for delivering air to the air jet nozzle; air jetted by the air jet nozzle can form an air curtain; the air curtain adjusting assembly is arranged at the air jet nozzle; and the control system is connected with the air curtain adjusting assembly and used for controlling the air curtain adjusting assembly so as to adjust the airflow rate and / or the air outlet angle of the air jet nozzle. According to the stand column flow-guide structure and the automobile, flow is guided through the air curtain, neither the structure nor the appearance of the stand column is affected too much, necessary functions of an automobile body are ensured, modeling of the automobile is not affected, meanwhile, the air curtain can guide the airflow to move smoothly along the automobile body, airflow passing through the air curtain can bypass an automobile window behind the stand column, accordingly, noise of air and noise of air vibration in the automobile are lowered, and comfort of the automobile is improved.

Description

technical field [0001] The invention relates to automobile noise control, in particular to a column guide 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 rais...

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
