Problems solved by technology

[0004] The purpose of the present invention is to provide a method for avoiding collisions at fork roads in view of the problem that the existing anti-collision devices at fork roads only use passive energy-absorbing technology to buffer the impact, while ignoring the problem that vehicles are prone to flicking and overturning

Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0057] This embodiment discloses a road collision avoidance method at a fork crossing, which uses a road collision avoidance device for a fork crossing to avoid collisions, such as Figure 1-9 As shown, the anti-collision device includes guardrail one, guardrail two, side bar one, side bar two, cross bar one, cross bar two, base, spring damping bar, anti-collision bar, anti-collision expansion bar one, anti-collision expansion bar Rod two, pull rod one, pull rod two, connecting rod one, connecting rod two, stretching rod. The rear end of the side bar is hinged with the front end of the first guard...

Abstract

The invention discloses a road anti-collision method for a crossway, which uses an anti-collision device to prevent collision, the method is achieved mainly by triggering anti-collision expansion rodson both sides of an anti-collision crossbar after a car hits a guardrail to increase the impact area between the car and the guardrail. The purpose of the method is to provide the rod anti-collisionmethod for the crossway to solve the problem that a prior anti-collision device only uses passive energy absorption technology to cushion the impact, but neglects the situation that the car is easy todrift or turnover. An anti-collision device in the anti-collision method can increase the contact area with the vehicle in time when the device is hit, has the function of cushioning and shock absorption, can prevent the car from drift and eliminates or reduces the probability of overturning of the car.

Description

technical field [0001] The invention belongs to the technical field of road traffic safety protection schemes. Specifically, it relates to a road collision avoidance method 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 passive ...
