When a vehicle passes through and contacts the speed bump mechanism in the device, extrusion force is applied to the arch memory alloy plate, so that the memory alloy plate has a downward moving trend, the extrusion force is transmitted to the rubber bag body below, so that water filled in the bag cavity flows to the flow limiting valve from the liquid outlet, and due to the action of the flow limiting valve, if the flow rate exceeds the set standard of the flow limiting valve, the flow will be blocked by the flow limiting valve, namely the volume of the rubber bag body is unchanged, so that the whole speed bump mechanism is still in a convex state and feeds back to the vehicle with a larger vibration sense; when the vehicle speed is low, the extrusion force on the rubber bag body is small, the water medium can normally flow only when the flow speed is smaller than the standard of the flow limiting valve, the water medium in the rubber bag body flows into the storage barrel through the one-way valve A, the volume of the rubber bag body is reduced, and the speed reducing belt mechanism is flattened, so that the vehicle can flatly run through the speed reducing belt mechanism.

Description

Self-adaptive deceleration strip

Technical Field

The invention belongs to the technical field of traffic facilities, and particularly relates to a self-adaptive deceleration strip.

Background

The deceleration strip is also called a deceleration ridge and is a traffic facility which is arranged on a highway and used for decelerating passing vehicles. The shape is generally strip-shaped and also has a point shape; the material is mainly rubber and also metal; generally, yellow and black are alternated to attract visual attention, so that the road surface is slightly arched to achieve the aim of vehicle deceleration. The special traffic safety setting is generally arranged on road junctions, industrial and mining enterprises, schools, residential community population and other road sections requiring vehicle slow down and traffic accidents are easy to cause, and is a novel special traffic safety setting for reducing the running speed of motor vehicles and non-motor vehicles.

Traffic calming can be divided into 3 major categories of methods for limiting the driving speed of motor vehicles, limiting the traffic volume of motor vehicles and limiting roadside parking, wherein the limitation of the driving speed of motor vehicles is divided into vertical, horizontal and road width reduction type control measures. The speed reducing belt is one of vertical speed controlling measures, and can change the height or material of some road section to force the motor vehicle to decelerate based on the psychological and physiological principle so as to reach the aim of safety.

The deceleration strip realizes deceleration by influencing the driving psychology of a driver. When a vehicle passes through the speed bump at a high speed, severe vibration is transmitted from the tire to a driver through the vehicle body and the seat, and the vertical curve can generate acceleration in a vertical direction, so that strong physiological stimulation (including vibration stimulation and visual stimulation) and psychological stimulation are generated. The physiological stimulation prompts the driver to generate strong uncomfortable feeling, and the psychological stimulation deepens unsafe doubts of the driver and further reduces the safety feeling of the driver to the road environment. In general, the greater the discomfort level the driver considers, the less safe the vehicle is traveling, i.e., the less safe the feeling is. Therefore, the arrangement of the deceleration strip can reduce the expected values of driving safety and riding comfort of the driver, and prompt the driver to select a lower expected vehicle speed. Under the guidance of the desired vehicle speed, the driver will actively drive the vehicle to approach and pass through the speed bump at a lower driving speed.

The prior deceleration strip product is directly fixed on a road surface, and the road surface is slightly arched after the deceleration strip product is installed, so that the running speed of motor vehicles and non-motor vehicles is limited. In the case of the conventional deceleration strip products, strong impact and bumpy feeling can be generated no matter the vehicle passes through the road deceleration strip at a high speed or at a low speed. Particularly, for the types of bicycles without shock absorbing devices, such as bicycles, the speed of the vehicles is not high, and the bumping impact feeling uncomfortable to people can be generated through the speed bump under the condition of low speed passing, so that a driver can generate extremely strong uncomfortable feeling, and potential safety hazards are easy to occur.

The common road speed bump is in a fixed arch structure, reduces the speed of a driving vehicle by a mandatory means, is low in cost and easy to popularize, but has many defects, one of which is as follows: even the vehicle that traveles reduces speed through still can give the more obvious vibration impression of vehicle feedback, causes the body of comparatively aversion to the passenger and feels, and more important causes too much too little intensity damage to vehicle shock absorber structure, to this patent number: CN201810890558.X discloses a self-adaptive deceleration strip, which can automatically adjust the height of a roof according to the speed of a vehicle, so that a low-speed vehicle can pass through the deceleration strip smoothly, but the structure of the deceleration strip is complex, the cost is high, and meanwhile, a transmission mechanism in the deceleration strip is easily damaged due to long-time and frequent vehicle rolling, so that the failure rate and the repair cost are high, and the deceleration strip is difficult to popularize.
