Municipal ventilation type pavement speed bump

Abstract

The invention belongs to the technical field of traffic tools, particularly relates to a municipal ventilation type pavement speed bump, and aims at solving the technical problems that an existing speed bump is lack of an effective buffer structure, and when a vehicle makes contact with the speed bump, the generated impact force is large. The municipal ventilation type pavement speed bump comprises a deceleration block and a metal fixing frame. A normally-blowing air bag is fixedly connected between the lower end of the deceleration block and the inner bottom end of the metal fixing frame, a metal fixing box is welded to the side end of the metal fixing frame, a normally-closed air bag is arranged on the inner side of the metal fixing box, a ventilation pipe is fixedly connected between the normally-closed air bag and the normally-blowing air bag, and a two-way adjusting pipe is arranged on the inner side of the ventilation pipe. By arranging the normally-blowing air bag, the normally-closed air bag and the ventilation pipe, the deceleration block can generate large jolt on a vehicle with the high speed, and therefore a driver can be promoted to pay attention to speed reduction when encountering the speed bump; and for vehicles passing slowly, the downward moving amplitude of the deceleration block is relatively large, and the bumping feeling of the vehicles passing is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a municipal ventilating road surface speed bump. Background technique [0002] The speed bump makes the road surface slightly arched to achieve the purpose of vehicle deceleration. It is generally set at highway crossings, industrial and mining enterprises, schools, residential quarter entrances, etc., where vehicles need to slow down and road sections that are prone to traffic accidents. New traffic-specific safety settings for non-motorized vehicle speeds. [0003] The speed bump has greatly reduced the occurrence of accidents at major traffic intersections, and is a new type of special facility for traffic safety. The vehicle is not only safe but also serves the purpose of buffering and decelerating during driving, so as to improve the safety of traffic crossings. [0004] The warning effect of the existing speed bumps is poor, and it is often discovered by the driver when ...

AI Technical Summary

Problems solved by technology

[0004] The warning effect of the existing speed bumps is poor, and it is often discovered by the driver when the vehicle reaches the front of the speed bump, especially at night, it is more difficult for the driver to detect in time; When rolling the speed bump, the impact force is relatively large, which is easy to cause damage to the internal parts of the vehicle, and no matter what speed the vehicle passes through, it will still produce a certain sense of bumps, and it will also bring extremely uncomfortable feelings to the occupants.
