Automobile bumper with multiple buffer mechanisms

Abstract

The invention discloses an automobile bumper with multiple buffering mechanisms. The automobile bumper with the multiple buffering mechanisms comprises a frame, a bumper, a left link, a right link andan energy absorbing box. A front end beam of the frame is fixedly connected with a fixed block, a left slider and a right slider are arranged on the both sides of the fixed block, a left spring is arranged between the left slider and the fixed block, a right spring is arranged between the fixed block and the right slider, the left link is hinged to the left slider, the right link is hinged to theupper surface of the right slider, the other ends of the left link and the right link are hinged to the bumper, the energy absorbing box is fixedly connected to the fixed block, and an energy absorbing plate is arranged inside the energy absorbing box. A shock absorption spring absorbs part of the impact energy and plays a certain buffering role, meanwhile the left spring and the right spring arecompressed, the left spring and the right spring further play a buffering role, when the impact force is too large, the energy absorbing plate absorbs most of the impact energy, the vehicle and the driver are protected, and an airbag is used for protecting the pedestrians, to reduce the hurt to the pedestrians caused by the collision.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an auto bumper with multiple buffer mechanisms. Background technique [0002] The car bumper is a safety device that absorbs and slows down external impact and protects the front and rear of the car body. Many years ago, the front and rear bumpers of automobiles were stamped from steel plates into channel steel, and riveted or welded together with the frame longitudinal beams. With the development of the automobile industry and the extensive application of engineering plastics in the automobile industry, automobile bumpers have become an important The safety devices of modern cars are also on the road of innovation. In addition to maintaining the original protection function, the front and rear bumpers of today's cars also need to pursue harmony and unity with the shape of the car body, and pursue their own lightweight. The existing bumper structure is relatively Simple, the shock abso...
