What modules make up the car body?
1 Answers
The car body modules consist of the body shell, car bumpers, car spoilers, engine hood, doors, windows, front sheet metal components, interior and exterior body trims and accessories, seats, as well as ventilation, heating, cooling, and air conditioning systems. The body shell serves as the installation base for all body components, typically referring to the rigid spatial structure formed by major load-bearing parts such as longitudinal beams, cross beams, pillars, and their connected sheet metal components. Doors are mounted on the body shell via hinges. Their structure is relatively complex and they are crucial components ensuring the functional performance of the body. These sheet metal components form spaces that accommodate the engine, wheels, and other parts. Car bumpers consist of three parts: an outer panel, cushioning material, and a crossbeam. They are designed to absorb and mitigate external impacts, protecting the front and rear of the body. During collisions, they help safeguard pedestrians and reduce injuries to occupants in high-speed impacts. Car spoilers primarily function to reduce the lift generated when the vehicle is traveling at high speeds, thereby preventing rear wheel lift-off. The engine hood ensures engine cooling and sound insulation, providing ride comfort while the engine operates at high speeds. It also offers dustproof and waterproof protection for the motor, battery, and various wiring in the engine compartment.
