Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of guardrails, in particular to a novel race car track guardrail. BACKGROUND

[0002] Karting track guardrails, also known as karting track dedicated protective walls, are part of track safety facilities, and are set at necessary positions outside the curb buffer zone or buffer zone to absorb the energy generated during the collision or out-of-control incident of karting, reduce the risk of injury to the driver and damage to the vehicle, and have the functions of collision prevention and protection. The main types of karting track guardrails include tire walls, chain guardrails (Z-shaped guardrails, U-shaped guardrails), and assembled guardrails.

[0003] Early karting track guardrails mainly used waste tires to form tire walls, which had the advantages of easy material procurement and low price, but had the disadvantages of poor safety, aesthetics, maintenance, and environmental friendliness. Nowadays, chain guardrails are commonly used for protection. Chain guardrails have a certain protective capacity by connecting multiple guardrails to each other, but have insufficient buffering and rebounding capacity. For example, Chinese patent 202220748373.7 discloses "a karting track water horse for karting track", which includes a track water horse body, a lower shell, an upper shell, and a main body pier. The main body pier is arranged at the middle position of the track water horse body, and the two ends of the main body pier are movably connected to the joint pier body. The lower shell is arranged at the bottom of the joint pier body, and the upper shell is arranged at the top of the joint pier body. The patent technology realizes kinetic energy buffering by allowing the track water horse body to rotate during the impact process, but is easily damaged during the impact process and is not easy to rebound for protection. Chinese patent 201910524935.2 discloses "a karting track guardrail", which is formed by connecting multiple U-shaped guardrail units in series through a telescopic connecting mechanism. Although the telescopic connecting mechanism can rebound to a certain extent during the impact process, the impact resistance is insufficient, and the position is easily shifted after the collision, which is not conducive to secondary collision protection.
