When a vehicle accident occurs, under the cooperation of the rotatable anti-collision ring and the tiltable warning column, the steering of the uncontrolled vehicle is assisted, and the situation that the uncontrolled vehicle is driven out of the road surface is avoided; meanwhile, under the action of external force, one side of the outer ring 7 extrudes rubber between the outer ring 7 and the inner ring 8, and impact force is further buffered.
As a protruding portion on the upright 1, the anti-collision ring is a first contact portion when a vehicle collides and scratches, and the damage probability of the anti-collision ring is far greater than that of other components. In this embodiment, the inner ring 8 is made of deformable plastic material; during the installation and replacement of the anti-collision ring, the inner ring 8 can be sleeved downwards from above the upright 1 to the first annular groove 10 of the upright 1 by forcefully expanding the inner ring. The anticollision ring of this embodiment is convenient for change to can change alone when anticollision ring damages alone, save material.
The inner side of the inner ring 8 is provided with a second annular groove 11, and a plurality of sliding lugs 9 are arranged in the second annular groove 11; the sliding lug 9 is in sliding connection with the second annular groove 11 on one side and the first annular groove 10 on the other side. In this embodiment, the sliding bump 9 is in a shape of a "convex" with the wider side facing the second annular groove 11 and the narrower side facing the first annular groove 10; the second annular groove 11 is a T-shaped groove which is matched with the shape of the sliding lug 9, and the sliding lug 9 is clamped in the second annular groove 11; the sliding bump 9 is made of rubber material.
When a collision occurs, the pressure generated by the vehicle collision warning column causes the sliding bump 9 to deform to a certain extent, depending on the degree of collision. When the degree of collision is lighter, the slip lug 9 hardly deforms because of pressure, and the anticollision ring rotates under the striking effect through the slip lug 9 with first annular groove 10, second annular groove 11 sliding connection, when dispersing the impact through self rotation, can carry out the deflection slope that corresponds according to the vehicle direction of travel, reaches the effect that supplementary vehicle turned to.
When the vehicle is out of control seriously, compared with the situation that the warning column is used for assisting in steering of the vehicle, the braking effect of the warning column is more important, the maintenance cost problem of the warning column is not considered any more, and the personal safety of personnel related to accidents is more important. When the degree of collision is heavier, the sliding lug 9 deforms under the action of pressure generated by collision, the sliding lug 9 expands towards the two sides of the first annular groove 10 and the second annular groove 11 due to extrusion, the friction force between the sliding lug 9 and the first annular groove 10 and between the sliding lug and the second annular groove 11 is greatly increased, the friction force for preventing the anti-collision ring from rotating is increased, and therefore the braking effect of the warning post on a vehicle is increased.
The embodiment can automatically adjust the action effect according to the severity of the accident, has simple structure and convenient installation, can also play a role in braking vehicles in serious traffic accidents, and reduces the probability of casualties.
