Problems solved by technology

Most of the existing road guardrails support metal plates or metal meshes through metal rods, and adopt a rigid structure to prevent cars from slipping on the road. The structure is relatively hard, so that when a car crashes into the guardrail at high speed, the car will be severely damaged. And after the collision, the driver and passengers will fly to the windshield of the car due to the effect of inertia after the collision, causing danger

Abstract

The invention relates to the field of road guardrails, in particular to a road guardrail with a collision protection structure, including a base. Through the set rubber buffer column, when the car hits the guardrail, the car will first contact with the rubber buffer column. Due to the characteristics of the rubber buffer column, the car will not be severely damaged by a rigid impact, and the car lies in the rubber After the collision of the buffer column, the speed of the car can be buffered. When the rubber buffer column cannot completely reduce the speed of the car, the vehicle of the car will be decelerated and buffered again under the resistance of the rubber buffer block, even if it still cannot completely reduce the speed of the car. Finally, the front of the car will be in contact with the rubber sheet, and the rubber sheet can softly buffer and decelerate the car again. When the rubber sheet cannot withstand the impact force and breaks apart, the car will be forced to stop under the protection of the metal protective plate. At this time, the car After a variety of buffer decelerations in the previous sequence, its speed is greatly reduced.

Description

technical field [0001] The invention relates to the field of road guardrails, in particular to a road guardrail with a collision protection structure. Background technique [0002] Highway fence is the most important transportation infrastructure. my country's expressway was developed in the 1980s, and it plays an important role in the development of the national economy and society. It is an important maintenance and safety guarantee facility for expressways. With the popularization of vehicles, traffic accidents occur frequently. Most of the existing road guardrails support metal plates or metal meshes through metal rods, and adopt a rigid structure to prevent cars from slipping on the road. The structure is relatively hard, so that when a car crashes into the guardrail at high speed, the car will be severely damaged. And after the collision, its driver and passengers will fly to the windshield of the car due to the effect of inertia after the collision and be in danger. ...
