Solid-liquid composite road speed bump

A solid-liquid composite, speed bump technology, applied in the directions of roads, roads, road signs, etc., can solve the problems of non-Newtonian fluid hardness changes that cannot be adjusted according to vehicle speed requirements, small speed adaptation range, and unsuitable speed limit requirements. To achieve the effect of small hardness, less bumps, and less electric energy

Problems solved by technology

However, this method is too sensitive to speed. Even if the speed is very low, the non-Newtonian fluid will still start to harden, and the hardness will reach the maximum value when the speed increases slightly. The adaptability to speed is small and cannot meet the speed limit requirements. When the vehicle meets the speed limit requirements and passes the speed bump, the hardness of the non-Newtonian fluid is already very large, causing the vehicle to still be very bumpy and not suitable for the speed limit requirements, and in this way, the hardness of the non-Newtonian fluid changes It cannot be adjusted according to the speed requirements, and the practicability is insufficient

Abstract

The invention discloses a solid-liquid composite road speed bump and relates to the technical field of road speed bumps. It includes the main body of the speed bump, which is made of flexible material; the main body of the speed bump includes the base section of the speed bump that is sequentially plugged and matched from left to right; a cavity is arranged in the base section of the speed bump; a magnetorheological damping is arranged in the cavity device; the magnetorheological damping device includes an electromagnetic coil fixed at the top of the cavity; a piezoelectric ceramic module for powering the electromagnetic coil is fixed at the bottom of the cavity; the cavity is correspondingly filled with magnetorheological fluid. The beneficial effect of the present invention is that it can effectively reduce the degree of bumping caused to the vehicle when the speed of the vehicle is low, and relieve the discomfort of the driver.

Description

Solid-liquid composite road speed bump technical field [0001] The present invention relates to the technical field of road speed bumps. Background technique Speed ​​bump is an important device used to limit the speed of the vehicle, when the vehicle passes the speed bump at a higher speed, it will produce strong Severe bumps, causing discomfort to the driver and reducing the sense of safety on the road environment, thereby affecting the driver's psychology and prompting him to Actively slow down before driving the vehicle through the speed bump. However, due to the hardness of the current speed bump, the resistance to the vehicle is The obstacle cannot be effectively alleviated, even if the vehicle passes the speed bump at a lower speed, it will still feel obvious bumps, causing driving Human aversion to speed bumps. In order to solve this problem, there are some speed bumps filled with non-Newtonian fluids, for example, the application number is The Chinese pat...
