What is the shell under the car trunk called?
1 Answers
The plastic shell under the car trunk is called the rear bumper. The rear bumper is a device that provides a buffer when the car or driver is subjected to impact forces. The rear bumper consists of three parts: the outer panel, the buffer material, and the crossbeam. It has the ability to reduce injuries to passengers during high-speed collisions. Here is some relevant information: 1. Car bumper: The outer panel and buffer material of the car bumper are made of plastic, and the crossbeam is formed by stamping cold-rolled sheet metal into a U-shaped channel. The outer panel and buffer material are attached to the crossbeam. The car bumper is located in most areas at the front and rear of the car. On the surface, it is designed to prevent damage to the vehicle's safety system caused by external impacts and has the ability to reduce injuries to passengers during high-speed collisions. Nowadays, it is increasingly designed for pedestrian protection. 2. Specific functions: Plastic bumpers have strength, rigidity, and decorative properties. From a safety perspective, they can act as a buffer during collisions, protecting the front and rear body of the car. From an aesthetic perspective, they can naturally integrate with the car body, forming a seamless whole and serving as an important decorative component of the car's exterior.
