Low-speed damping mechanism of deceleration strip

Abstract

The invention relates to the technical field of traffic safety, and discloses a low-speed damping mechanism of a deceleration strip, the low-speed damping mechanism comprises a shell, the upper end of an inner cavity of the shell is movably sleeved with a movable block, the cross section of the movable block is T-shaped, and the lower end of the movable block is provided with a first movable cavity. By arranging the low-speed damping mechanism, when a vehicle passes through the deceleration strip at a low speed, after a tire is pressed on the upper surface of the movable block, air at the lower end of the movable block moves downwards into the air cavity through the vent hole when the movable block overcomes the elastic force of the first spring, so that the movable block moves downwards by a certain distance; therefore, the gradient of the deceleration strip on the road surface is reduced, the vibration amplitude is small when a vehicle with a low speed passes through the deceleration strip, and when the vehicle passes through the deceleration strip at a high speed, air at the lower end of the movable block cannot quickly move into the air cavity due to the small hole diameter of the vent hole, so that the height change amplitude of the movable block is small. Therefore, the effect of warning deceleration is achieved.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a low-speed damping mechanism of a speed bump. Background technique [0002] Speed ​​bumps are also called speed bumps. They are traffic facilities installed on roads to slow down passing vehicles. They are generally strip-shaped or dot-shaped. The material is mainly rubber or metal. The color is usually yellow and black to attract visual attention. , so that the road surface is slightly arched to achieve the purpose of vehicle deceleration. It is generally set at highway crossings, industrial and mining enterprises, schools, residential quarters, etc., where vehicles need to slow down and road sections that are likely to cause traffic accidents. It is used to reduce motor vehicles, non- New traffic-specific safety settings for motor vehicle speeds. [0003] Speed ​​bumps decelerate by affecting the driver's driving psychology. When the vehicle passes the speed bump at a ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing speed bumps proposed in the background technology, the present invention provides a low-speed shock absorbing mechanism for speed bumps, which has the advantages of low-speed vibration reduction and damp slowing, and solves the problems raised in the above background technology. technical issues
