Description

Technical Field

[0001] The utility model relates to the technical field of high-speed anti-collision guardrails, in particular to an emergency channel anti-collision device. Background Art

[0002] High-speed anti-collision guardrails can use the deformation of the soil base, columns and beams to absorb the energy generated during a car collision, and force the out-of-control vehicle to change direction, thereby restoring it to its normal driving direction, preventing the vehicle from running off the road, and protecting the vehicle and passengers.

[0003] The utility model patent with patent application publication number CN 218454368 U discloses an emergency channel anti-collision device, including an automatically folding air cushion, a first upper guardrail is movably installed on one side of the automatically folding air cushion, an upper movable groove is fixedly installed on one side of the first upper guardrail, an upper movable shaft is movably installed in the inner cavity of the upper movable groove, and a first outer movable plate is movably installed on one side of the upper movable shaft.

[0004] The utility model uses an automatic folding air cushion. When a traffic accident occurs, the railing will be hit hard. The automatic folding air cushion can delay the impact and can be automatically folded and stored. In addition, a double-layer protection is achieved through the first upper guardrail, the first lower guardrail, the second upper guardrail, and the second lower guardrail. The double-layer protection is more solid and has better protective function.

[0005] However, the above device still has some shortcomings in actual use. The most obvious one is that although the automatic folding air cushion can play a good role in delaying and cushioning the impact, after an actual collision, it is very easy to be damaged due to scratches on the surface parts of the vehicle, which in turn leads to air leakage. At this time, the automatic folding air cushion can no longer continue to play a role in the collision process, and it also needs to be repaired or replaced later, which is inconvenient in actual use.

[0006] Therefore, it is necessary to invent an emergency channel anti-collision device to solve the above problems. Utility Model Content
