An airbag cushioning device for road isolation belts

Abstract

The invention belongs to the technical field of road safety equipment, and in particular relates to an airbag cushioning road isolation belt device, comprising: a bracket, a collision roller, a cushioning airbag and a piezoelectric power generation device, the collision roller includes a rubber cylinder and a mounting bearing; the left and right ends of the cushioning airbag It is hinged with the corresponding bracket; the piezoelectric power generation device includes: a rubber pad laid on the road surface, a power generation transmission column, a fixed plate, piezoelectric sheets distributed along the inner radial circumference of the fixed plate, a large gear and a small gear, and a power generation transmission column The lower end of the piezoelectric plate has sawtooth, the sawtooth meshes with the teeth of the small gear, one end of the piezoelectric sheet is fixed on the fixed plate, and the other end meshes with the teeth of the large gear, the fixed plate is fixed on the road, and when the tire rolls over the rubber pad, the power generation transmission column The downward movement drives the pinion gear and the large gear to rotate, causing the non-fixed end of the piezoelectric sheet to swing, causing the piezoelectric sheet to bend and discharge. The invention can convert the kinetic energy of the cars passing on the road into electric energy, and can buffer the collision of the cars.

Description

technical field [0001] The invention belongs to the technical field of road safety equipment, and in particular relates to an airbag cushioning device for road isolation belts. Background technique [0002] The road separation belt is to separate the left and right traffic lanes. Now it is generally a green belt. When a traffic accident occurs, it is easy to hit the railing or separation wall of the green belt, causing damage to the car. Especially on the highway, when the speed of the vehicle hits the railing and the separation wall on both sides of the road, it is easy to cause greater damage to the vehicle. [0003] Especially on highways, in order to ensure the power consumption of street lighting, etc., it is necessary to erect poles and cables in a large area, and the power supply cost is high; in order to maintain and sprinkle water on the road, the sprinkler needs to drive from one high-speed entrance to another high-speed exit. If the water in the car compartment i...
