Abstract

The present invention discloses a composite bumper which is made up by using steel spring plate and foamed plastics and applicable to various automotive vehicles. When a collision accident occurs between vehicles, said composite bumper mainly is used for greatly lightening damaged extent and reducing compact force and vibrating force to vehicle and passengers. Said invented composite bumper is simple in manufacturing process and low in cost.

Description

Group and bumper/spoiler

The present invention relates to a kind of Federal bumper, be meant especially and can when automobile crashes, absorb, slow down impulsive force, a kind of combined bumper of vibratory force.

At present, the bumper/spoiler of using on China's automobile, inreal super to safety effect, what have can only prevent slight degree of crash, the bumper/spoiler that also useful shaped steel is made, when crashing, very stiff and demanding, impulsive force, vibratory force are passed to automobile once, and it is a lot of to cause car to ruin the accident that the people hinders, how when auto against, slow down impulsive force, vibratory force, alleviate damage degree, slow down the impact of passing to driver occupant, vibration.

In view of this, the purpose of this invention is to provide a kind of combined bumper, utilize spring plate, the impulsive force that produces when the foamed plastic touching lever progressively absorbs collision and a kind of unitized construction of vibratory force.

The object of the present invention is achieved like this, it is characterized in that: bumper/spoiler, and touching lever, bow type spring, stock, quarter butt can independent, capable of being combined uses, and bumper/spoiler is by spring plate, foamed plastic, the outer decoration, and can be by dress steam pocket, sensor.

Owing to adopt such scheme, the minimizing accident takes place, and after having an accident, can not have or reduce degree of tortuosity, slows down personal casualty.
