What is the small round hole on the rear bumper?

[DelLogan]

The small round hole on the rear bumper is a towing eye, used for towing. Here is some relevant information about bumpers: 1. Component Function: The car bumper (also known as an impact beam) is located in most areas at the front and rear of the vehicle. It is designed to prevent external damage from affecting the vehicle's safety systems and has the capability to reduce injuries to passengers during high-speed collisions. Nowadays, more and more bumpers are designed for pedestrian protection. 2. Origin and Definition: The car bumper is a safety device that absorbs and mitigates external impacts, protecting the front and rear parts of the vehicle body. Twenty years ago, the front and rear bumpers of cars were mainly made of metal materials, using steel plates with a thickness of more than 3 millimeters pressed into U-shaped channel steel, with chrome-plated surfaces. They were riveted or welded to the longitudinal beams of the frame, with a relatively large gap between the bumper and the body, making it seem like an additional component.
