AI Technical Summary

Technical Problem

The existing guardrail structure has rigid connections, which makes it difficult for objects to recover from deformation. When a vehicle crashes into it, the strong impact force can cause injury to the people inside the vehicle.

Method used

The guardrail bracket is fixed to the road, and the impact force is buffered through a multi-weakening structure consisting of flexible weakening, spring rod assembly, hydraulic storage sleeve and hydraulic telescopic rod.

Benefits of technology

To maximize the reduction of external impact, minimize damage to vehicles and people, and improve the resilience of guardrails.
