Abstract

The invention discloses a telescopic step-by-step layered buffering vehicle bumper, and belongs to the field of vehicle bumpers. The bumper comprises a bumper shell assembly, an energy absorption block, a bumper beam, a bumper support, a first-stage buffer mechanism, a second-stage buffer mechanism, a valve base assembly and a bearing plate. The primary buffer mechanism comprises a first support,a second support and a plurality of spiral springs; the first-stage buffer mechanism can ensure that the bumper absorbs energy during torsional vibration rotation. Therefore, overlarge torsional vibration and impact amplitude in impact are attenuated; a common amplitude value of a resonance region in impact is inhibited and a large torque is transmitted; even if the collision direction of the external force is uncertain, when the vehicle bumper is collided, multi-stage buffering can be carried out through the two-stage buffering mechanism, that is to say, the two-stage buffer mechanism can convert the vertical impact load into the horizontal transverse impact load, and can buffer the horizontal transverse impact load to play an important role in improving the impact energy absorption effect, improving the vehicle collision safety and protecting pedestrians.

Description

technical field [0001] The invention relates to the field of automobile bumpers, and more specifically, relates to a retractable step-by-step buffer automobile bumper. Background technique [0002] Automobiles are important modern means of transportation. With the rapid development of society and the improvement of people's economic living standards, the automobile industry has developed rapidly in recent years. As an important part of automobile safety design, automobile bumpers absorb and slow down external impacts, protect The safety devices at the front and rear of the car body are increasing day by day with people's requirements for car safety performance. [0003] Existing automobile bumpers are in pursuit of their own light weight. The general automobile front-end bumper system mainly includes bumper shell, bumper bracket, energy-absorbing block, bumper reinforcement beam, front wall and longitudinal beam connection module, among which, Plastic bumper shells, energy-...
