The invention discloses an automobile front bumper assembly, which belongs to the technical field of automobile parts, and can be combined with the existing buffer material to realize pre-buffering byutilizing a pressure hood, form high extrusion on a force reducing layer after absorbing energy and deforming, further buffer the impact force and improve the strength of the automobile front bumperassembly; pressure is transmitted to the chemical force layer on the rear side of the force reduction layer through the force transmission pressing balls, non-Newtonian liquid and the chemical force balls in the chemical force layer start to play a role in pressure resistance, and particularly, after the chemical force balls utilize the characteristic of liquid energy absorption, substances capable of enabling water to be frozen quickly are actively released inside the chemical force balls; the water after energy absorption is forced to be frozen and converted into solid characteristics to resist impact force, ice is melted by means of the characteristic that heat is generated by friction, the secondary springback phenomenon caused by the impact force is avoided, meanwhile, an automobile body can be obviously cooled in the impact process, secondary fire damage caused by huge impact is avoided, and the service life of the automobile is prolonged; and the anti-collision effect and the safety effect of the automobile bumper are effectively improved.
本发明公开了一种汽车前保险杠总成,属于汽车部件技术领域,本发明可以通过与现有的缓冲材料结合,利用压气罩实现预缓冲,并在吸收能量形变后对减力层形成高度挤压,进一步对冲击力进行缓冲的同时,依靠传力压球将压力传递至减力层后侧的化力层上,化力层内的非牛顿液体和化力球开始发挥抗压作用,尤其是化力球在利用液体吸能的特点后,在内部主动释放出可以使水快速结冰的物质,迫使吸能后的水结冰转变固体特性对冲击力进行抵抗,并且利用摩擦生热的特性再对冰进行融化,契合冲击力带来的二次回弹现象,同时车身在冲击过程中会实现明显的降温,避免因此巨大冲击带来的火灾二次伤害,有效提高汽车保险杠的防撞效果和安全作用。
