Problems solved by technology

At present, it is generally a method of setting a push rod and a buffer zone at the front and rear of the car to reduce the losses caused by car accidents. This method can theoretically reduce the impact of car collisions, but a large number of accidents in reality show that this The effect of the method is very limited
In addition, current technology cannot prevent injuries to pedestrians

Embodiment 1

[0013] Embodiment one: see figure 1 , a composite anti-collision device, comprising a T-shaped ejector bar, an elastic material, a brittle material, a locking spring, a locking ring, and a bracket.

[0014] Brittle and elastic materials are placed alternately.

[0015] Brittle materials are corrugated in shape.

[0016] Multi-layer brittle materials are designed with layers of different thicknesses.

[0017] The elastic material is in the shape of a flat plate with a round hole in the middle for the T-shaped mandrel to move back and forth.

[0018] The working principle of the present invention is: when the impact occurs, the T-shaped ejector rod moves back and forth, and the force generated by the impact is transmitted to the elastic material, and the elastic material disperses and transmits the force to the corrugated brittle material, and causes part of the brittle material to break. And the fracture of each brittle material will absorb part of the impact force, so that ...

Abstract

A composite anti-collision device comprises a T-shaped ejector rod, elastic materials, fragile materials, a locking spring, a locking ring and a bracket. The fragile materials and the elastic materials are alternately arranged. The fragile materials are corrugated. The fragile materials in a plurality of layers are designed to have different thicknesses. The elastic materials are shaped like flat plates; and circular holes are formed in the middle of the elastic materials and can allow the T-shaped ejector rod to move forward and backward. According to the technical scheme provided by the invention, during a collision, energy generated by the collision is transmitted to the fragile materials through the elastic materials and the energy generated by the collision is absorbed through the breakages of the fragile materials so that a purpose of protecting a main body is achieved. The composite anti-collision device can be applied to bumper bars at the front part and the rear part of an automobile or other places needing to prevent collision.

Description

technical field [0001] The present invention relates to the technical field of automobiles, and may also relate to the technical field of safety protection. Background technique [0002] Due to being in a state of high-speed motion all the time, automobile accidents are mainly collision accidents, including vehicle-vehicle collisions, vehicle-to-object collisions, and car-to-people collisions. When a collision occurs, the huge impact force generated by the collision of automobiles is the main cause of damage to people and objects. At present, the method of setting ejector rods and buffer zones at the front and rear of the car is generally used to reduce the losses caused by car accidents. This method can theoretically reduce the impact of car collisions, but a large number of accidents in reality show that this The effect of the method is very limited. In addition, current technology cannot prevent injuries to pedestrians. Contents of the invention [0003] In order to ...
