Abstract: This paper takes the issue of excessive vertical clearance between the lower body of the instrument panel and the glove box after a certain vehicle model's instrument panel assembly is tightened as an example, and systematically analyzes the adverse contributions and impacts of the glove box, the lower body of the instrument panel, tolerance adjusting nuts, and the cross car beam on the issue of excessive clearance. Based on the analysis, resolution and verification process of the problem, in order to address the size matching problem that occurs on the actual vehicle, define engineering development goals, and develop an effective positioning pin deviation and pre deformation strategy to control the vertical clearance on both sides of the glove box. On this basis, further exploration, research, and summarization will be conducted to provide reference for the matching design of dashboard and glove box in other subsequent projects.
