Barrier-free automatic lifting speed bump and control method

Abstract

The invention discloses a barrier-free automatic lifting speed bump and a control method. The speed bump comprises a radar speed indicator, four guide rails, a speed reducing plate, four sliding wheels, a plurality of upper supporting rods, a plurality of lower supporting rods, a plurality of link rods, a left push-pull rod, a right push-pull rod, two groups of push-pull electromagnets, a plurality of push-pull springs, a thrust electromagnet, a plurality of thrust springs, a thrust rod and a control device. The barrier-free automatic lifting speed bump has no barrier to the normal running vehicles, and can forcibly decelerate the over-speed vehicles, so that the road running comfortableness and the running safety can be improved, the noise is reduced, the service life of a tyre is prolonged and the overhauling expense is reduced. In addition, the control method is simple and convenient.

Description

technical field [0001] The invention relates to a speed limiting device for road vehicles, in particular to a barrier-free automatic lifting deceleration belt and a control method. Background technique [0002] At present, the speed bumps installed on the road are all strips, dots or block structures directly fixed on the road surface, the purpose is to force motor vehicles to slow down, so as to ensure that traffic participants pass through crossings, schools, houses and accident-prone roads. life safety. Although setting speed bumps can reduce the occurrence of traffic accidents to a large extent, there are still many problems, such as: the expansion screws left on the road after the speed bumps are damaged are likely to puncture the car tires, causing the vehicle to lose control; the noise of vehicle bumps Seriously interfered with the lives of the surrounding residents; the existing speed bumps cannot distinguish between motor vehicles and non-motor vehicles, so it is v...

Problems solved by technology

Although setting speed bumps can reduce the occurrence of traffic accidents to a large extent, there are still many problems, such as: the expansion screws left on the road after the speed bumps are damaged are likely to puncture the car tires, causing the vehicle to lose control; the noise of vehicle bumps Seriously interfered with the lives of the surrounding residents; the existing speed bumps cannot distinguish between motor vehicles and non-motor vehicles, so it is very easy to cause non-motor vehicles to skid in ice and snow weather; and personnel comfort; the existing speed bumps cannot reflect the principle of "rewarding slow and punishing fast", that is to say, even if the vehicle is driving at a low speed, it will still hit the speed bump, thus causing damage to the tires and the car body

[0003] In view of the above problems, relevant scholars have carried out a certain degree of research. Chinese patent applications No. 200720021665.6, 200720174551.5, 201120018191.6, 201120103041.5 and 201010261228.8 respectively disclose the design scheme and implementation method of various new speed bumps. However, the existing technology The route has the following problems: the use of hydraulic load mitigation can reduce the impact of the deceleration belt on the car body and tires, but the vehicle speed needs to be very low. You will still feel the obvious impact through the speed bump. If you drive at a low speed of 10km / h, although the impact will be reduced, it will cause local traffic congestion during the rush hour, which will cause inconvenience to traffic participants; The design of the sloping plate combined with the spring reduces the cost of the deceleration belt, and has good mechanical properties, but it can only be used for one-way lanes. If the road needs temporary repairs, changing the one-way lane to a two-way lane will cause obstacles to the reverse vehicle, so Applications are limited

In addition, in the existing more than 80 patent application documents related to speed bumps, none of them reflect the fairness of "slow rewards and fast penalties"
