In order to realize that the two sections of speed reducing belt assemblies move up and down to drive the two first pistons 5 to move left and right, the left side and the right side of the first piston cylinder 3 are respectively provided with a first gear 10 and a second gear 11, and the two gears are fixedly connected through a shaft in the front-back direction; a piston rod 12 is arranged on the outer side of each first piston 5, a transverse first rack 13 is connected to the outer end of each piston rod 12, each first rack 13 is meshed with the lower side of the first gear 10 on the same side, a vertical second rack 14 is connected to the lower surface of the top plate 1 of each speed reduction belt assembly, and each second rack 14 is meshed with the outer side of the second gear 11 on the same side.

In order to enhance the stability of the deceleration strip assembly, a plurality of vertical guide posts 20 are installed below the top plate 1, vertical guide holes 21 corresponding to the guide posts 20 are formed in the road surface below the deceleration strip, and the guide posts 20 are inserted into the guide holes 21 and can slide up and down.
In order to ensure that the top plate 1 can automatically bounce when no load is applied, a plurality of second pressure springs 22 are arranged below the top plate 1.
In order to ensure the sealing performance of the first piston cylinder 3, a sealing ring is arranged at the matching position of the first piston cylinder 3 and the piston rod 12.
For the convenience of installation and protection, a protective shell 23 is arranged outside the first piston cylinder 3, the second piston cylinder 4 and the plurality of gears are all installed in the protective shell 23, and the second rack 14 penetrates through the protective shell 23 to be meshed with the second gear 11.
When the deceleration strip assembly is used specifically, a pit body capable of accommodating a lower protective shell 23 and guide holes 21 into which guide columns 20 can be inserted are drilled on a road surface on which the deceleration strip is to be installed, the protective shell 23 and mechanisms in the protective shell 23 are placed in the pit body and fixed, the periphery of the pit body can be reinforced by concrete and other materials, then the end parts of two deceleration strip assemblies are abutted against the road surface above the protective shell 23, and a plurality of guide columns 20 are inserted into the corresponding guide holes 21.
When a motor vehicle drives through the speed reducing belt, two front wheels of the motor vehicle can be respectively pressed on the left speed reducing belt component and the right speed reducing belt component, the top plate 1 can be pressed to descend, and the outer sides of the two side plates 2 extend outwards in the process that the two wheels drive through the speed reducing belt components, so that the speed reducing belt components have the tendency of gradually extending into a flat plate; the top plate 1 is pressed and lowered to drive the second racks 14 below the top plate to move downwards, the two second racks 14 move downwards to drive the two second gears 11 to rotate, the two second gears 11 rotate to drive the two first gears 10 fixedly connected with the two second gears to rotate, the two first gears 10 drive the two second racks to move inwards, so that the two first pistons 5 are pushed to move inwards through the two piston rods 12, the right first piston 5 moves leftwards to cross a right orifice of the first channel 15, and the left first piston moves rightwards to cross a left orifice of the second channel 16, so that hydraulic oil between the two first pistons 5 is isolated from the cylinder bodies outside the two first pistons 5; the two top plates 1 are pressed downwards continuously, the two first pistons 5 move inwards continuously, the pressure of hydraulic oil between the two first pistons 5 opens the pressure valve 8 on the liquid outlet loop, the hydraulic oil enters the second piston cylinder 4 through the liquid outlet check valve 17, the pressure valve 8 and the flow limiting valve 9 and pushes the second piston 6 to move backwards by overcoming the elastic force of the first pressure spring 7, meanwhile, due to the action of the flow limiting valve 9, the speed of the hydraulic oil entering the second piston cylinder 4 is limited, namely the inward movement speed of the two first pistons 5 is limited, namely the descending speed of the two top plates 1 is limited, therefore, if a vehicle passes through the speed bump in a relatively high speed, the pressure plate cannot be pressed downwards completely in the time when the vehicle passes through the speed bump, and if the vehicle passes through the speed bump in a relatively low speed, the top plates 1 are pressed completely, the vehicle cannot bump, and the speed of the vehicle passing through the speed bump is higher, the smaller the degree of the deceleration strip is pressed down, the stronger the bumping feeling of the vehicle is, the function of automatically adapting to the vehicle speed can be realized, and different speed limit values can be set by changing different diameters of the flow limiting valve 9 or the first piston cylinder 3.
After the vehicle drives away from the deceleration strip, the top plate 1 rises under the action of the second pressure spring 22 to pull the two first pistons 5 to move outwards, and hydraulic oil in the second piston cylinder 4 is extruded by the second piston 6 under the action of the first pressure spring 7 and flows back into the first piston cylinder 3 through the liquid return branch and the liquid return check valve 18.
When a non-motor vehicle such as a bicycle or an electric vehicle passes through the speed bump, even if the speed bump is slow, the pressure valve 8 may not be opened because the pressure of the hydraulic oil by the first piston 5 is small due to the light weight, and even if the pressure valve 8 is opened, the top plate 1 may not be depressed because the flow rate of the hydraulic oil having a small pressure is slow, so that the non-motor vehicle feels a significant bump, which is very inconvenient for the non-motor vehicle.
Therefore, the present invention solves this problem by providing a first channel 15 and a second channel 16, and the specific principle is as follows: because the non-motor vehicle is a single-row wheel, when the non-motor vehicle runs through the speed bump, only one top plate 1 can be pressed down, only one first piston 5 moves inwards, when the top plate 1 on the left side is pressed down, the first piston 5 on the left side moves rightwards, because the first piston 5 on the right side does not move, the first channel 15 communicates the cylinder bodies on the left side and the right side of the first piston 5 on the left side, the first piston 5 on the left side moves rightwards, hydraulic oil between the two first pistons 5 flows to the left side of the first piston 5 on the left side through the first channel 15, and therefore the first piston 5 on the left side moves rightwards almost without resistance, namely, the top plate 1 on the left side can be smoothly and quickly pressed down to enable the non-motor vehicle; similarly, when the right top plate 1 is pressed down, the right first piston 5 moves leftwards to extrude the hydraulic oil between the two first pistons 5 to the right side of the right first piston 5 through the second channel 16, so that the right first piston 5 moves leftwards without resistance, namely, the right top plate 1 can be smoothly and quickly pressed down to enable the non-motor vehicle to pass through without obstacles; when the non-motor vehicle drives away from the speed bump, the top plate 1 rises and resets under the action of the second pressure spring 22, the corresponding first piston 5 moves outwards, and hydraulic oil flows back to a position between the two first pistons 5 through the first channel 15 or the second channel 16.
The invention has the following remarkable advantages: firstly, the invention designs a hinged combined type deceleration strip main body which can descend when being pressed, designs two piston cylinders and limits the flow velocity of hydraulic oil between the two piston cylinders through a flow limiting valve 9, realizes the function of adjusting the height of the deceleration strip according to the vehicle speed through the linkage of the descending speed of the deceleration strip and the flowing speed of the hydraulic oil, and can effectively solve the problem that the vehicle still generates large jolt when the vehicle speed is reduced to the speed limiting range of the traditional deceleration strip; moreover, the invention fully considers and solves the inconvenience brought by the traditional speed reducing belt to the non-motor vehicles, and the single top plate 1 can be pressed without resistance by arranging the first channel 15 and the second channel 16, thereby ensuring that the non-motor vehicles can rapidly descend through the speed reducing belt, and further leading the non-motor vehicles to pass through without barriers.
In conclusion, the intelligent vehicle speed automatic judging system can automatically adapt to the vehicle speed, can automatically judge the motor vehicle or the non-motor vehicle, is intelligent and efficient, and has simple and ingenious structure and strong practicability.
