Abstract: At present, the research on the air outlet focuses on structural optimization design, howling, aerodynamic noise, etc, while the research on the operating force of the air outlet is limited to qualitative analysis, and no quantitative mechanism formula has been solved. At present, the mechanism of the operating force of the automobile air outlet is not clear, and after the production of the air outlet, the measured operating force of the air outlet is adjusted according to the adjusted clearance to meet the standard requirements, and the design and production process are not controllable. By analyzing the structure of the air outlet, the mechanism formula and influencing factors of the operating force are determined in this paper, and the parameters in the mechanism formula are also determined through linear fitting by the combination of simulation and experiment, which provides a general method for analyzing the operating force mechanism of the air outlet. By solving the mechanism formula of the vertical operating force, the size of the outlet can be calculated according to the required operating force, which can guide the design and manufacture of the air outlet.
