Abstract

The present invention relates to a collision prevention shock-absorption safety bumper device at the front side, the rear side and the lateral side of a vehicle, which comprises a bumper and a pernetti, wherein the bumper is a shell body which is around the car and stretches in the vertical direction of the car. At least two buffer springs are arranged in the bumper in the vertical direction of the car to compress the stretching shell which is orderly screwed with a car body and a girder through the pernetti. The present invention has simple structure. The safety bumper is the shell which stretches in the vertical direction of the car. The buffer springs arranged in the bumper makes the stretching shell to be in an inherent stress state. Once the care suffers collision, the collision force is drastically reduced under the action of the stretching shell and the buffer springs, and thereby, the car and the personal safety is effectively ensured.
