Abstract: As one of the important functional parts of automobile interior trim, the design of air register determines whether the performance of automobile can meet the requirements of automobile attributes. This paper introduces the composition of the air register, its location and layout requirements in the design and development process, and the corresponding regulations that it needs to meet. It also introduces the matters needing attention and some important parameters of the knob, wheel and vane of the air register in the design process. In order to provide corresponding reference for the subsequent design of similar structures. According to the actual use of the vehicle, the air register is the high-frequency use area of passengers. The stiffness of the air register is analyzed by using the finite element analysis method. The analysis results show that the deformation of the air register is greater than the standard requirements, and the structure needs to be optimized. By increasing the diameter of the shaft on both sides of the vane, it is concluded that the stiffness of the air register vane meets the design requirements. Through the research of this paper, the mold repair cost caused by design defects can be reduced.
