Problems solved by technology

[0003] However, the height and stiffness of the existing speed bump protruding from the road are fixed, causing all passing vehicles to bump and jump, which will not only cause discomfort to passengers, but also have a negative impact on the vehicle itself
Even if the driver has slowed down the speed in advance, due to the existence of the speed bump, he still has to endure the vibration caused by the speed bump, which is unfair to the vehicles that have complied with the rules
In addition, the hard contact between the speed bump and the vehicle will cause great damage to the vehicle and the speed bump itself, and the economy is poor.
Chinese patent CN101818485B discloses a deceleration belt without rigid impact on the vehicle. This structure can overcome the rigid impact between the deceleration belt and the vehicle, but its rigidity is still fixed and cannot completely eliminate the vibration and bumpy feeling of the vehicle at low speeds.
Chinese patent CN103061287A discloses a stiffness-adjustable deceleration belt using a magnetorheological damping device, which can change the stiffness of the deceleration belt according to the vehicle speed and reduce the vibration of low-speed vehicles, but requires the cooperation of speed sensors, power supply equipment and special control equipment. In order to achieve its design purpose, the system is complex, low reliability, and poor economy

Abstract

The invention discloses an intelligent deceleration strip. The intelligent deceleration strip comprises a deceleration strip hollow shell of an elastic material, and a porous material which is filled in the shell; the pores of the porous material are filled with a shear thickening liquid. By filling the shear thickening liquid in the porous material, the intelligent decelerating strip is able to automatically change the rigidity based on the speed of the vehicle passing by, jolt and warn high-speed vehicles, let low-speed vehicles pass through comfortably without jolting, punish the high-speed vehicles and release the low-speed vehicles, thereby achieving humanized intelligent guide and control of the speed of the vehicles passing by.

Description

technical field [0001] The invention relates to a deceleration belt used at road intersections, in particular to an intelligent deceleration belt whose stiffness can be automatically adjusted according to the speed of passing vehicles. Background technique [0002] In order to limit the driving speed of vehicles on urban road crossings, schools, residential quarter entrances, etc., which need to slow down, speed bumps are generally set on these road sections to remind passing vehicles to slow down. Commonly used speed bumps are generally made of hard rubber, alternated with yellow and black to attract visual attention, and make the road surface slightly arched to achieve the purpose of vehicle deceleration. [0003] However, the height and stiffness of the existing speed bump protruding from the road are fixed, causing all passing vehicles to bump and jump, which will not only cause discomfort to passengers, but also have a negative impact on the vehicle itself. Even if the...
