Abstract: Automotive floor access covers are widely used in the whole vehicles, but the access covers currently used in the market generally have problems such as inconvenient disassembly and installation, and poor sealing effect, which largely affect the maintenance efficiency and passenger environment. By designing the structure of the access cover, studying the material process, improving the sealing of the corners through rounded corners, straight edges and other forms of buttressing, and choosing a suitable opening position to ensure that high-density noise reduction insulation foam can be installed to improve the maintenance efficiency in the event of vehicle failure, this paper hopes to provide the effective help for technicians engaged in the design and research of new energy bus.
