[0032] The present embodiment discloses a liftable speed bump 10, including a speed measuring subsystem, a lifting power subsystem and a speed bump device. The speed measuring subsystem accurately measures the speed of the vehicle ahead, and transmits the information to the lifting power subsystem after detecting that the vehicle is speeding. The lifting power subsystem lifts the main speed bump through the internal structure, and at the same time, the travel switch and the limit block lock the speed bump, so that the speed bump remains lifted for a period of time. At this time, when a vehicle passes by, the driver will feel a bumpy feeling, and the vehicle is forced to slow down. After a period of time, the travel switch and the limit block release the control, and the push rod 3 automatically unloads the force to lower the main speed bump. The present embodiment can force the vehicle speed to be within the speed limit range, realizes intelligent management, and has the advantages of simple structure, easy use, and wide applicability.

[0033] The speed bump includes a speed measuring subsystem, a lifting power subsystem and a speed brake device; the speed measuring subsystem includes a speedometer 9 and an electric signal transmission device; the lifting power subsystem includes an electric signal receiving device, a motor, a push rod support 1, a push rod 3, a push rod flange 4, a lower box 5, a travel switch and a limit block; the speed brake device includes a speed reduction main board 6 and a speed reduction side board, which are connected by a hinge 11; the speed measuring subsystem is wirelessly connected to the lifting power subsystem, the boss is located at the output end of the push rod 3 and the push rod flange 4, the boss is fixedly connected to the lifting power subsystem and the speed brake device by screws, and the lifting power subsystem is connected to the speed brake device by the boss. The lower box 5 in the lifting power subsystem is buried underground, the electric signal receiving device is embedded in the inner side of the lower box 5, and is connected to the motor by wireless connection. The motor is located inside the lower box, and the motor is connected to the drive shaft through the shaft and the push rod 3 column, and the drive shaft then transmits power to the push rod 3 and the push rod flange 4; the travel switch and the limit block are connected by a compression spring. The speed brake device includes a speed brake main plate 6 and a speed brake side plate, which are connected by hinges and screws; when the main speed brake is raised, the vehicle and the driver will be forced to slow down when they are bumped, and the system can withstand the weight of passing vehicles.

[0034] The speed measuring subsystem is composed of a speedometer 9 and an electrical signal transmission device, and has the function of collecting and importing vehicle speed. The speedometer 9 is set on the roadside, collects the real-time speed of the vehicle within a preset distance range, and inputs the collected speed information into the speed measuring subsystem through the electrical signal transmission device. The speed analysis module in the speed measuring subsystem has the functions of information import and signal output. The control module compares the speed information collected by the speedometer 9 with the preset speed value, and through analysis and judgment, gives real-time feedback on the lifting speed bump, issues lifting instructions, and improves the driving safety and comfort of people and vehicles. After receiving the lifting instructions fed back by the speed measuring subsystem, the lifting power subsystem takes corresponding lifting measures. The lifting power subsystem can lift the main board and side panels in the speed bump device through the push rod 3 to realize the lifting function.

[0035] The speed measuring subsystem has the function of detecting whether the speed of the vehicle in front exceeds the set threshold. When the speed meter 9 detects that the speed of the vehicle in front exceeds the set threshold, the overspeed signal will be transmitted to the electric signal receiving device in the lifting power subsystem through the electric signal transmission device. The lifting power subsystem has the function of controlling the lifting and lowering of the speed bump, and is the core power part of the lifting speed bump 10. This system includes an electric signal receiving device, a motor, a push rod support 1, a push rod 3, a push rod flange 4, a lower box 5, a travel switch and a limit block. After the electric signal receiving device receives the overspeed signal, it can control the motor to lift the push rod 3 and the push rod flange 4, and the push rod 3 and the push rod flange 4 then lift the speed bump device, thereby achieving the effect of reducing the vehicle speed; the electric signal sending device and the receiving device use one or more of the LoRa module, 2.5G communication module, 3G communication module, 4G communication module, and 5G communication module.

[0036] The liftable speed bump 10 is composed of a speed measuring subsystem, a lifting power system and a speed bump device. The speed measuring subsystem is composed of a speedometer 9 and an electric signal transmission device, and has the function of detecting whether the speed of the vehicle in front exceeds the set threshold. When the speedometer 9 detects that the speed of the vehicle in front exceeds the set threshold, the overspeed signal will be transmitted to the electric signal receiving device in the lifting power subsystem through the electric signal transmission device; the lifting power subsystem includes a push rod support 1, a push rod 3, a push rod flange 4, a lower box 5, and a limit device 2 (travel switch and limit block). The push rod flange 4 and the push rod 3 are the parts that directly contact the speed bump, which can control the speed bump to rise and fall. The push rod support 1 and the lower box 5 play the role of providing a load-bearing and stable environment for the speed bump system. The lower box 5 can bear the weight of the vehicle and remain stable through structural design and material selection, ensuring the normal operation of the speed bump; the speed bump device has the function of reducing the speed of the vehicle. When the main speed bump is raised, the vehicle and the driver will be forced to slow down when they are bumped.

[0037] The lifting speed bump is set on the road surface, and a speed meter 9 is set at a distance L from the lifting speed bump. The speed measuring range of the speed meter 9 is set to M, so that it can detect the instantaneous speed of the vehicle at any position less than or equal to M from the speed meter 9 in real time, and convert it into an electrical signal to transmit it to the lifting power subsystem.

[0038] Assume that the speed limit of a road is v, and the vehicle travels on a straight road section at a speed v, with the center of mass of the vehicle as the origin, and the distance between the vehicle and the speedometer 9 is the change value M. When a vehicle enters the speed measurement area and its speed is measured, there may be the following three situations:

[0039] When the speed exceeds the maximum speed limit value v, that is, v is greater than v, the electrical signal transmission device transmits the overspeed signal to the electrical signal receiving device, thereby controlling the motor to lift the push rod 3 and the push rod flange 4, and then lift the main speed bump. The column adjusts the speed bump height, and the travel switch and the limit block can lock the push rod 3 and the push rod flange 4, and set the speed bump lifting time t. When the vehicle passes the speed bump, it slows down. When the time t>t, the push rod 3 unloads the force, and the speed bump drops.

[0040] When the vehicle speed does not exceed the maximum speed limit v, that is, v is less than v, the speed bump system will not be triggered, allowing the vehicle to pass smoothly;

[0041] When the vehicle exceeds the speed limit in the speed measurement interval M, v is greater than v, and then decelerates to within v in M, v is less than v, the speed bump rises and lasts for t time, and then falls after t time. The speed bump rise or fall time must be controlled within L / v. At this time, the speed bump has fallen before the vehicle passes through the speed bump, and the driver will not feel bumpy.

[0042] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
