The present invention relates to a telescopic buffer car bumper with layered layers, belonging to the field of car bumpers; Mechanism, valve seat assembly, receiving plate; the first-level buffer mechanism includes the first support, the second support, and multiple coil springs; the first-level buffer mechanism can ensure that the bumper absorbs energy during torsional vibration and rotation, thereby attenuating excessive impact during impact. Large torsional vibration and impact amplitude, and suppress the resonance amplitude of the resonance area in the impact and transmit a large torque, even if the external force collision direction is uncertain, it can also make the car bumper pass through the secondary buffer when it is collided The mechanism performs multi-level buffering, that is, the secondary buffering mechanism can convert vertical impact loads into horizontal and lateral impact loads, and can buffer horizontal and lateral impact loads. It will play an important role in improving impact energy absorption, improving vehicle collision safety and pedestrian protection. effect.
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-...
