Description
Technical Field
[0001] The utility model relates to the technical field of multifunctional pavement, in particular to a multifunctional pavement with auxiliary braking function. Background Art
[0002] With the development of science and technology, the number of cars is increasing, and smart driving cars are gradually entering people's horizons. The safety of car driving is also being paid attention to. The braking time of the car is an important factor affecting driving safety. With the development of intelligent systems, the braking time and braking acceleration of a car are important indicators to measure whether a road construction meets the requirements. Asphalt pavement is the most widely used pavement on highways now, but the existing asphalt pavement is basically a single-type pavement without other functions. In addition, affected by the performance of existing cars, the braking distance is generally long, which poses a safety hazard. Utility Model Content
[0003] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and to propose a multifunctional road surface with auxiliary braking function, which can greatly shorten the braking distance of the car and improve the safety of the car driving.
[0004] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a multifunctional road surface with auxiliary braking function, including an electromagnet, an AC transformer box, an acceleration sensor, an asphalt road surface, an iron core, a wire and a coil; the electromagnet is composed of an iron core and a coil wound around the iron core, and is placed 5-10 cm below the surface layer of the asphalt road surface. When powered on, the magnetic force generated by the electromagnet can attract the metal under the chassis of the car. There are multiple electromagnets, which are distributed at intervals along the road direction of the asphalt road surface; the AC transformer box is placed on the side of the road and is connected to the electromagnet through a wire, and its output voltage is 220V; the acceleration sensor is arranged on the outside of the road, and its shell is a metal box, and is respectively connected to the electromagnet and the AC transformer box through wires, and is used to detect the acceleration of the vehicle when it is running to control the electromagnet to turn on or off.
[0005] Furthermore, the shell of the AC transformer box is made of aluminum alloy.
[0006] Furthermore, the housing of the acceleration sensor is made of aluminum alloy.
[0007] Furthermore, the iron core is soft iron.
[0008] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0009] The utility model applies auxiliary braking function to the road surface, which can effectively shorten the braking time of the car. When an emergency occurs, current passes through the electromagnet, and the generated magnetic force can attract the metal under the car chassis, thereby increasing the friction between the car and the road surface. At the same time, the braking time of the car can be recorded as needed, synchronized to the system, and provided to the transportation department for research. BRIEF DESCRIPTION OF THE DRAWINGS
