Abstract

The invention discloses a road anti-collision device applicable to a crossing. The anti-collision device is mainly used for triggering anti-collision deployment bars arranged on both sides of an anti-collision cross bar to be deployed after a vehicle collides with a guardrail, so as to increase the impact area of the vehicle and the guardrail. The object of the invention is to provide the road anti-collision device applicable to the crossing aiming at solving the problem that the existing road anti-collision device applicable to the crossing only adopts the passive energy absorption technologyto cushion collision, and ignores the fact that the drifting and tipping of the vehicle are easy to occur. The anti-collision device can increase the contact area with the vehicle in time when an collision occurs, has the shock absorbing function, can prevent the drifting of the vehicle, and prevents or reduces the tipping probability of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of road traffic safety protection equipment. Specifically, it relates to a road collision avoidance device especially applied to a fork. Background technique [0002] On ordinary roads, expressways and other roads, a "V" is formed at the fork of the road, which is a special road section with frequent traffic jams and traffic accidents. Accidents usually occur because the vehicle enters a fork in the road and the driver violates the law. For example, when many vehicles are not sure of the driving direction, they will temporarily stay at the fork or temporarily change the driving direction, and the driver is tired driving, or in an environment with poor lighting conditions, it is very easy to cause the vehicle to collide with the guardrail. The incidence of traffic accidents is high. [0003] At present, most of the existing anti-collision devices designed for forks in the road adopt the principle of passiv...
