A municipal ventilating road deceleration belt

Abstract

The invention belongs to the technical field of vehicles, in particular to a municipal ventilation-type road deceleration belt. Aiming at the technical problem that the existing deceleration belt lacks an effective buffer structure and the impact force is relatively large when the vehicle touches the deceleration belt, it is now The following scheme is proposed, including the deceleration block and the metal fixed frame. A constant drum airbag is fixedly connected between the lower end of the deceleration block and the inner bottom of the metal fixed frame. A metal fixed box is welded on the side of the metal fixed frame. The normally closed airbag is fixedly connected with a ventilator between the normally closed airbag and the normally inflated airbag, and a two-way regulating tube is arranged inside the ventilator. The present invention realizes that the deceleration block will produce larger bumps for vehicles with a faster speed through the provided normally-drum airbags, normally-closed airbags and ventilation tubes, thereby helping to urge the driver to pay attention to deceleration when encountering a deceleration belt; For vehicles, the deceleration block moves down a relatively large range, which reduces the bumpy feeling when the vehicle passes by.

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.
