Description

Technical Field

[0001] The utility model relates to the technical field of speed bumps, in particular to a highway speed bump. Background Art

[0002] Speed ​​bumps are also called speed bumps, which are traffic facilities installed on roads to slow down passing vehicles. They are usually in strip or dot shapes. Highway speed bumps are mainly made of rubber, but also metal or cement. They are usually yellow and black to attract visual attention, making the road surface slightly arched to achieve the purpose of slowing down vehicles.

[0003] Existing highway speed bumps slow down vehicles by using a speed reduction surface with a slope. However, the degree of bumps in this method is fixed, and there will be greater bumps whether the vehicle passes quickly or slowly. For example, a Chinese patent discloses a "highway speed bump" with an application number of "CN202320415869.7". When a vehicle passes through the speed bump body at a low speed, the non-Newtonian fluid is in liquid state, and the wheels roll over the highway speed bump, the supporting skeleton undergoes elastic deformation, and the non-Newtonian fluid flows to both sides of the wheels. When the vehicle passes, it is almost not blocked by the speed bump body, making it difficult for people in the vehicle to be bumped; when the vehicle passes through the highway speed bump quickly, the non-Newtonian fluid in the speed bump body is solidified by force to form a solid, which blocks the vehicle's progress and causes severe bumps when the vehicle passes, so as to achieve the purpose of improving the driver's deceleration. However, the speed bump surface is easily damaged in the wind and sun, and once damaged, it cannot be used anymore. Utility Model Content
