What are the types of automobile frame structures?

[SanKarter]

There are three types of automobile frame structures. Below is a detailed introduction: Body: The body structure includes the body shell, front panel components, doors, exterior decorative parts, interior trim parts, body accessories, seats, ventilation and heating systems, etc. Load-bearing components: The body shell typically consists of major load-bearing elements (such as longitudinal beams, cross beams, and brackets) and the connected panels, forming a rigid spatial structure. Most bus bodies have clearly visible frameworks, while passenger car bodies and truck cabs usually have less apparent frameworks. Interior: The interior trim components of the body include surface coverings such as instrument panels, headliners, sidewalls, seats, and carpets. In passenger cars, natural or synthetic fiber textiles, leather, artificial leather, or multilayer composite materials are widely used as decorative materials. In buses, fiberboard, engineering plastic sheets, aluminum sheets, patterned rubber sheets, cardboard, and composite decorative panels are commonly employed as decorative materials.
