Abstract: As one of the important functional parts of interior trim, the design of glove box determines whether the performance of produced products can meet the needs of customers. This paper introduces the composition of the glove box and how to define some important parameters in the design and development process, such as the volume requirements of the glove box, the design and positioning strategy of the welding structure parameters of the glove box, the overlapping design of the lock tongue and the lock tongue sleeve, the size of the buckle opening and the design of the opening limit block of the glove box, in order to provide corresponding reference for the subsequent design of similar structures. At the same time, combined with the abnormal noise of glove box often occurred in the process of vehicle road test, this paper introduces the modal analysis of glove box by using the finite analysis ways. The analysis results show that the first-order frequency and second-order frequency of glove box are greater than 45 Hz, which meets the design requirements. Through the research of this paper, the mold repair cost caused by design defects can be reduced.
