What are the 3D Digital Model Design Specifications for Yanfeng Interior and Exterior Trim?
1 Answers
The following are the design specifications for Yanfeng interior and exterior trim: 1. Interior design specifications: The boundary dimensions of the instrument panel must meet the extreme requirements of equipment, process, and materials; confirm the basic structural parameters of the instrument panel based on the overall vehicle design task book; it is recommended to use a tubular beam structure to simplify the structure and reduce costs; attachments such as the instrument panel tubular beam, glove box, and steering wheel cover should be reused as much as possible to shorten the development cycle, improve reliability, and effectively reduce costs; the draft angle of protruding or recessed parts of plastic components should be controlled between 0-25° to reduce mold design and manufacturing costs; the external protruding features of attachments installed on the main body should be minimized to reduce mold design and manufacturing costs, etc. 2. Exterior design specifications: The outer surface of the vehicle body must not have any sharp parts facing outward, nor any protrusions that may increase the risk of scratches or impacts or worsen the injuries of those hit in a collision due to their shape, size, orientation, or hardness; the fillet radius of protruding parts on the outer surface of the vehicle body must not be less than 2.5mm, this requirement does not apply to parts protruding less than 1.5mm from the outer surface of the vehicle body or parts protruding between 1.5mm and 5mm but with smooth outward-facing parts; when the material hardness of protruding parts on the outer surface of the vehicle body does not exceed Shore A hardness 60HA, the fillet radius may be less than 2.5mm.
