Description

Technical Field

[0001] The utility model relates to the technical field of bumpers, in particular to a three-section bumper for an automobile. Background Art

[0002] The bumper usually refers to the protective device at the front and rear of the vehicle, which is used to absorb the impact during a collision to protect the vehicle and passengers. It is also called "fender" or "anti-collision beam" in some places.

[0003] However, the existing three-section bumpers on the market still have some disadvantages. For example, the three-section bumpers are usually connected by bolts, which are easily affected by the environment, such as moisture, corrosion or vibration, which may cause the bolts to loosen or corrode, affecting the stability and safety of the bumper. Secondly, the three-section bumper without a buffer structure cannot effectively absorb and disperse the impact force during a collision, and can only resist the impact force through its own rigidity, which will cause the vehicle occupants and the vehicle itself to be subjected to greater impact, thereby increasing the possibility of injury and damage.
