Description

Technical Field

[0001] This utility model relates to the field of emergency escape lanes, and more particularly to a high-speed emergency escape lane that uses buffer railings. Background Technology

[0002] Emergency escape lanes, also known as emergency parking lanes, highway safety belts, or highway escape lanes, are special lanes designed for handling emergencies on highways. Their main function is to provide a safe area for vehicles in distress to stop, await assistance, or move to another location in the event of vehicle breakdowns, traffic accidents, or other emergencies. Escape lanes are typically located on the shoulder or side of the highway and are designed to be sufficiently wide, have a smooth surface, and high visibility so that drivers can easily identify them and stop safely. Highways have high speeds and heavy traffic volumes; without dedicated escape areas, vehicle breakdowns or accidents can often lead to more serious traffic accidents or congestion. To mitigate this risk, many countries and regions include dedicated escape lanes in the design and construction of highways to ensure that vehicles can quickly and safely move to a safe area in the event of a breakdown, avoiding secondary accidents or traffic disruptions. However, these emergency escape lanes, in addition to basic deceleration, can cause vehicles to become stuck in the deceleration sand and gravel, resulting in significant towing costs. In addition, if a vehicle loses control and enters the emergency escape lane, and the direction is not controlled while the speed is not reduced, it may crash into the guardrail, resulting in injury to the driver and the people inside the vehicle.

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all. The description of at least one exemplary embodiment is actually only illustrative, not as any limitation on the utility model and its application or use. Embodiment 1

[0025] The embodiment provides a high-speed risk avoidance lane applied with a buffer rail, comprising: a deceleration buffer lane main body 1, and a buffer rail 2 arranged on both sides of the deceleration buffer lane main body 1.

[0026] The surface of the buffer rail 2 is provided with a shear thickening buffer bag 3.

[0027] The deceleration buffer lane main body 1 comprises a deceleration pavement 102;The deceleration pavement 102 is provided with a deceleration strip, and the surface of the deceleration strip is provided with a shear thickening liquid.

[0028] The vehicle is decelerated and stopped by the deceleration strip of the deceleration pavement 102 and the shear thickening liquid on the surface of the deceleration strip. When the vehicle is tilted and hits the buffer rail 2, the shear thickening buffer bag 3 arranged on the buffer rail 2 is used for buffering and deceleration, so as to avoid the vehicle from falling off the lane. The shear thickening liquid is converted from "liquid state" to elastic "solid state" instantaneously when it contacts with the car, so as to absorb the impact force, thereby playing a deceleration role. Embodiment 2

[0029] The embodiment 2 provides a high-speed risk avoidance lane applied with a buffer rail based on the embodiment 1, and the difference lies in that:

[0030] The deceleration buffer lane main body 1 is of a buffer slope structure, which is beneficial to vehicle deceleration. The deceleration buffer lane main body 1 further comprises a gravel pavement 101, which is paved with gravel. A vehicle first passes through the gravel pavement 101 and then passes through a deceleration pavement 102. The vehicle is first decelerated by the gravel pavement 101, and the resistance between the gravel and the vehicle tires is large, so that the speed is reduced. Then the vehicle passes through the deceleration pavement 102 for secondary deceleration, and finally stops. At least 8 deceleration strips are provided on the deceleration pavement 102. Two different deceleration modes are used to ensure safe deceleration and stopping of the vehicle.

[0031] The shear thickening buffer 3 comprises a shear thickening liquid layer 301 and a plastic foam layer 302. The shear thickening liquid layer 301 is arranged on the surface of the plastic foam layer 302 and contacts the impacting vehicle. The surface of the plastic foam layer 302, which contacts the buffer barrier 2, is provided with a magic tape 303. The magic tape 303 cooperates with the groove on the buffer barrier 2 to increase the installation stability. The plastic foam layer 302 comprises plastic foam and cloth for wrapping the plastic foam. The surface of one side of the cloth is sewn with the magic tape 303, and the other side is coated with the shear thickening liquid. When the vehicle is deflected in the direction of the vehicle, it impacts the buffer barrier 2. First, the shear thickening liquid layer 301 is contacted, and the impact force is absorbed by the shear thickening liquid. The plastic foam layer 302 arranged below the shear thickening liquid layer 301 can reduce the damage to the vehicle. The shear thickening buffer 3 is quickly installed and removed through the magic tape 303.

[0032] The shear thickening liquid used in the shear thickening liquid layer 301 is added with nanometer carbon tubes to improve the shock absorption effect of shear thickening. The shear thickening liquid used on the deceleration strip can also use the shear thickening liquid added with nanometer carbon tubes or the shear thickening liquid without nanometer carbon tubes. The shear thickening liquid is in a liquid state at room temperature and can be stored and transported separately from other replacement equipment.

[0033] In this embodiment, after the vehicle enters the deceleration buffer lane main body 1, it first passes through a section of gravel pavement for deceleration, and then enters the deceleration pavement. The vehicle is simultaneously decelerated by the deceleration strip and the shear thickening liquid on the deceleration strip, the deceleration effect is improved, and the vehicle is prevented from being stuck in the gravel by continuously decelerating through the gravel pavement. The shear thickening liquid on the deceleration pavement 102 can be directly coated with shear thickening liquid after being impacted by the vehicle. The doping of gravel particles will not affect its use. When the vehicle enters the deceleration buffer lane main body 1 and is deflected to impact the buffer barrier 2, the shear thickening buffer 3 provided on the buffer barrier can protect the buffer barrier, protect the vehicle, and also decelerate the vehicle. The shear thickening buffer 3 can be conveniently and quickly replaced.
