The invention belongs to the technical field of road safety equipment and in particular relates to an air bag hydraulic buffer intelligent road isolation strip. The air bag hydraulic buffer intelligent road isolation strip comprises a bracket, a collision safety air bag, a hydraulic damper and a piezoelectric power generation device, wherein the collision safety air bag comprises a piezoelectric arc-shaped plate, a reset spring, an air bag housing, an air bag body, a gas generator and a rubber cover; the piezoelectric power generation device comprises a rubber gasket, a power generation transmission column, a fixed disc, a piezoelectric sheet, a rack wheel and a pinion; sawteeth are arranged on the lower end of the power generation transmission column, the sawteeth are engaged to teeth of the pinion; one end of the piezoelectric sheet is fixed on the fixed disc while the other end is engaged to teeth of the rack wheel; and when a tyre rolls over the rubber gasket, the power generation transmission column moves downward to induce swinging of the non-fixed end of the piezoelectric sheet, so that the piezoelectric sheet bends to discharge. The air bag hydraulic buffer intelligent road isolation strip provided by the invention converts kinetic energy of the automobile passing on the pavement into electric energy, and can buffer car collision.
