Abstract

The invention provides a weight reducing safety type automobile bumper. An inner lever and an outer lever are clamped together, a bumper enclosure structure is formed, an annular cavity is formed, aninner tire provided with an air valve is placed in the cavity and inflated through the air valve, a rectangular weight reducing hole is formed in the inner side of the outer lever, thickening boards distributed at equal intervals are arranged on the outer edge of the weight reducing hole, vertical reinforcing ribs are arranged between the adjacent thickening boards, inclined reinforcing ribs are arranged on the two sides of each vertical reinforcing rib, a U-shaped groove used for clamping is formed in the outer side of the outer lever, and bilaterally-symmetrically-distributed clamping sheetsare arranged on the middle portions of the two side edges of the U-shaped groove. The weight reducing safety type automobile bumper is simple in structure, convenient to use, maintain and repair, safe, reliable, capable of effectively reducing harm to people and an automobile in the collision process, stable and reliable in work and capable of effectively preventing a secondary collision, the gravity of the bumper is reduced through the weight reducing hole, the anti-collision strength of the bumper is improved through the supporting thickening boards, and the strength of the automobile bumper is improved again through the reinforcing ribs.

Description

technical field [0001] The invention belongs to the technical field of automobile bumper equipment, in particular to a weight-reducing safety automobile bumper. Background technique [0002] With the continuous improvement of people's living standards, automobiles have become an indispensable means of transportation for people to travel. Therefore, the demand for various parts of automobiles is also increasing. Automobile bumpers are an important part of the front of automobiles. Protecting key components such as the engine at the front of the car during a collision is a safety device that absorbs and slows down external impact and protects the front and rear of the car body. Existing bumpers generally minimize vehicle damage during a collision by strengthening their own strength. However, after a collision, the vehicle stops suddenly and may cause a secondary collision. It is necessary to add a reminder or a protective device to the bumper. At present, automobile bumpers n...
