In modern urban construction and planning, bridges are built across rivers, lakes, and seas to enable vehicles, pedestrians, etc. to pass smoothly. After the construction of municipal bridges, guardrails are generally installed on the bridges to protect vehicles traveling on the bridges, which can provide a certain degree of protection for vehicles in the event of an accidental collision.
[0003] However, it still has some shortcomings. For example, the existing bridge protection structure is relatively simple. When a vehicle collides unexpectedly, the guardrail and the vehicle have a small buffering force, so a hard collision with great force will occur, which will cause serious damage to both the bridge and the vehicle, and may cause the vehicle to be destroyed and people to be killed. In serious cases, the vehicle will rush off the bridge deck. The bridge protection device has the problem of low safety factor.
