Where is the car's bumper located?
2 Answers
The car's bumper is located at the front and rear of the vehicle, referred to as the front bumper and rear bumper respectively. As an automotive component, the bumper is prone to scratches and collisions during daily driving, making it one of the most frequently repaired parts. Functions of the bumper: The bumper serves as a device to absorb and mitigate external impacts during collisions, providing a cushioning effect to protect both the vehicle and its occupants. In addition to maintaining its original protective function, modern vehicle bumpers also aim for harmony and unity with the car's body design while pursuing lightweight construction. Most passenger car bumpers are made of plastic, commonly known as plastic bumpers. These consist of three main components: the outer panel, cushioning material, and crossbeam. Plastic bumpers offer strength, rigidity, and decorative appeal. From a safety perspective, they provide impact absorption during collisions, protecting the front and rear of the vehicle. Aesthetically, they integrate seamlessly with the car body, becoming an important decorative element of the vehicle's exterior. Structural composition: The outer panel and cushioning material are made of plastic, while the crossbeam is formed from cold-rolled steel sheets approximately 1.5mm thick, pressed into U-shaped channels. The outer panel and cushioning material are attached to the crossbeam, which is then connected to the vehicle's frame rails with screws for easy removal. The plastic used in these bumpers primarily consists of polyester and polypropylene materials, manufactured through injection molding. Bumper modifications: Adding protective bars to front and rear bumpers: Many car owners choose to install additional protective bars on their bumpers during modifications. This modification involves minimal changes to the original components, and the protective bars are relatively inexpensive compared to full bumper replacements, with moderate technical requirements. This makes it suitable for enthusiasts who enjoy modifications but lack extensive knowledge, while also improving safety and visual appeal. Installing 'body kit' components on original bumpers: This is another common method of bumper modification in daily driving scenarios. The Mercedes AMG kit serves as a representative example. These modifications are performed on the original bumper structure, with relatively simple installation processes that can give the vehicle a more aggressive and sporty appearance. Painting additional colors on original or modified bumpers: Some car enthusiasts may choose to paint different colors on their original bumpers or added protective bars. This type of modification covers a larger area and offers more personalization. However, owners are advised to consult relevant traffic authorities before proceeding to avoid potential legal issues.
I also didn't know the exact position of bumpers when I first started driving, until I got them scraped and finally figured it out. The bumpers are located at the outermost edges of the front and rear of the car. The front bumper sits below the license plate, extending from beneath the headlights to near the front wheels, while the rear bumper spans from above the license plate to the rear wheels. These areas are typically about 30-40 cm above the ground, and the corners of the front and rear bumpers are the most prone to scratches during daily driving. Once, while reversing without paying attention, I scraped the rear bumper against a wall, and replacing it cost me nearly two thousand yuan. Though made of plastic and seemingly insignificant, bumpers actually play a crucial role in protecting the car's frame. Now, I've developed the habit of parking farther away from curbs, since repairing bumpers can be quite expensive.
