Problems solved by technology

The speed reduction belt can play a very good role in forcing the speed limit of the driving vehicle, but because the existing speed reduction belt mainly uses the principle of discomfort caused by the bumps when the vehicle is driving, so that the driver drives at the speed limit. The following conditions will still be plagued by this discomfort, so it is necessary to invent a speed bump that is stable at low speeds (or without bumps) when the vehicle is running at high speeds.

Abstract

The invention discloses a liftable deceleration belt, which comprises a deceleration belt plate, a support rod, a slider hinge and a vehicle speed adaptive action device for adjusting the elevation angle of the speed reduction belt plate according to the vehicle speed. The fixed end of the speed reduction belt plate is hinged to the ground , the free end is hinged to the pole through the slider hinge, the other end of the pole is hinged to the ground, and the vehicle speed adaptive action device acts on the bottom of the speed bump plate. According to the present invention, the protruding state of the deceleration belt can be changed according to the speed of passing vehicles. When the speed of passing vehicles is higher than a certain set value, the new speed reduction belt can remain in a raised state; when the speed of passing vehicles is lower than a certain set value, the new speed reduction belt can be lowered, Therefore, the vehicle can pass through the new speed reduction belt smoothly (or without bumps). The present invention is conducive to better planning the speed of vehicles traveling on road sections, thereby making the driving road safer.

Description

technical field [0001] The invention relates to a deceleration belt for traffic roads, in particular to a liftable deceleration belt. technical background [0002] Speed ​​bumps are mainly used on downhill road sections, such as road sections before road checkpoints, to actively or passively decelerate vehicles, and it plays an important role in road traffic safety. Existing deceleration belts are generally made of rubber or cast steel, with a simple structure consisting of pieces of rubber or cast steel units. From the tire to the driver through the body and seat, the vertical curve of the speed bump can generate a vertical acceleration, generate strong physiological stimulation (including vibration stimulation and visual stimulation) and psychological stimulation. Physiological stimulation promotes a strong sense of discomfort for the driver, while psychological stimulation deepens the driver's doubts about safety and further reduces the driver's sense of safety on the ro...
