[0002] The front bumper of an automobile is a protective device installed at the front of the automobile for preventing collision and absorbing impact energy. It is usually injection-molded from plastic, with relatively low overall rigidity. At the same time, the front bumper is large in size, has many surrounding mating parts, and the dimension chain is too long. Therefore, the installation and positioning of the front bumper is a technical problem that is not easy to solve. At present, the most common way to install and position the front bumper is to fix the front bumper through the middle bracket at the position of the front hood and the fender brackets on both sides. This method is difficult to assemble and cannot achieve accurate positioning of the bumper, ultimately resulting in poor cooperation between the bumper and surrounding parts and a decline in appearance quality.

[0003] An existing installation and positioning structure of a front bumper includes a body fender and a front bumper. The bumper is installed and positioned by the installation surface located inside the front bumper below the styling surface and the plastic bracket located on the fender being embedded with each other, so that the installation surface of the front bumper is not affected by the styling surface. However, this positioning system can only perform positioning in the X direction and the Z direction and cannot achieve positioning in the Y direction. During the installation process, the front bumper is prone to lateral deviation, resulting in poor cooperation between the front bumper and the fender and the headlight.
