Front safety device for automobile knocking

The invention discloses a front safety device for automobile knocking, and relates to the field of automobile parts. The front safety device for the automobile knocking is characterized in that the safety of passengers in the automobile and the safety of the automobile are not seriously threatened when the automobile is driven at a low speed and knocks. Meanwhile, since an automobile speed is low,the damping coefficient of a variable coefficient damper is low, a buffering effect is good, and the safety of pedestrians can be favorably protected. When the driving speed of the automobile is high, under a situation of knocking, a pressure value measured by a pressure sensor can exceed a certain limiting value, and a super glue ejector is triggered and is ejected to an engine cover. If the pedestrian is knocked at the time, the pedestrian is scooped up and upwards rolled, is stuck by the super glue without rolling to be below wheels to be crushed. In addition, since the speed is high, thecoefficient of a hydraulic
