The invention discloses a speed bump capable of performing height adjustment according to a vehicle speed. The speed bump comprises a controller, an oil tank, an electromagnetic directional valve, aninfrared speedometer, a base, a speed bump body and a hydraulic cylinder, wherein the infrared speedometer is used for detecting the vehicle speed on a road surface; the base is arranged on the road surface; the speed bump body is arranged on the base; the hydraulic cylinder is buried under the road surface; the output end of the infrared speedometer is connected with the controller; the controller is connected with the control end of the electromagnetic directional valve; the oil tank is communicated with the hydraulic cylinder by virtue of the electromagnetic directional valve; the output shaft of the hydraulic cylinder is connected with the base; and the infrared speedometer and the speed bump body are arranged in sequence along a vehicle driving direction. The speed bump is capable ofperforming height adjustment according to the vehicle speed.
Description
technical field [0001] The invention belongs to the technical field of road deceleration belts, and relates to a deceleration belt that can be adjusted in height according to vehicle speed. Background technique [0002] The speed bump is a traffic facility installed on the road to slow down passing vehicles. It is generally installed at road crossings, industrial and mining enterprises, schools, residential quarter entrances, etc., where vehicles need to slow down and where traffic accidents are likely to occur. Slightly arched to achieve the purpose of vehicle deceleration, it is a safety device used to reduce the speed of motor vehicles. When the driver passes the speed bump at a higher speed, the severe vibration will bring strong physiological and psychological stimulation, which will make people feel uncomfortable and prompt them to slow down. However, when passing through the speed bump at a slow speed, the physiological stimulation received by people has not been red...
