Where is the car's bumper located?

There are two types of car bumpers: the front bumper is located at the front of the car, and the rear bumper is at the rear. The relevant introduction to car bumpers is as follows: Structural composition: The outer panel and cushioning material are made of plastic, and the crossbeam is formed by stamping cold-rolled sheet metal with a thickness of about 1.5mm into a U-shaped channel. The outer panel and cushioning material are attached to the crossbeam, which is connected to the frame longitudinal beams with screws, allowing for easy removal. The plastic used for bumpers mainly consists of polyester and polypropylene materials, manufactured through injection molding. Basic functions: Dispersing impact force: When a collision occurs, the bumper is the first point of contact. It then distributes the force to the energy-absorbing boxes on both sides, which transmit it to the left and right front longitudinal beams, and then to other structural parts of the car body. Protecting pedestrians: Some may have seen bumpers made of foam online and thought it was a cost-cutting measure. In fact, while bumpers used to be made of steel, this was dangerous for pedestrians in accidents. Plastic and foam bumpers help mitigate the impact on pedestrians' legs, especially the lower legs, and, when combined with a well-designed front bumper, reduce the severity of injuries. Poor-quality bumpers, however, can cause significant damage to the car's components.
I often drive to and from work, and the car's bumpers are in very prominent positions at the front and rear—the front bumper is right under the hood, near the front wheels, while the rear bumper is beneath the trunk, close to the rear wheels. They are mainly made of plastic or composite materials, which are soft and serve to absorb impact during minor collisions, protecting both the occupants and critical components of the car. For example, when reversing into a small object, the bumper absorbs the force first, preventing damage to the internal structure. Additionally, newer car models now feature sensors installed in the bumpers, such as parking sensors, to enhance parking safety. Although their position may seem simple, maintaining them is quite important. Last time I washed my car, I noticed scratches on the bumper and ignored them, only for rainwater to accumulate and cause rust. So, it's wise to park carefully and avoid frequent scrapes. Overall, bumpers are fixed in place and easily noticeable, and their design has evolved to be more stylish, no longer just bulky metal blocks.
