The invention provides a flexible, buffering, energy-absorption and power-generation type strain deceleration strip for vehicles. The deceleration strip comprises an outer body bearing movable piece, an inner body bearing base, an outer frame tank body, a three-section type hydraulic lifting jack, a touch control and reset system, a power transmission connecting rod mechanism, a speed changing gear system, a voltage supply system, power generators and a storage battery. The flexible, buffering, energy-absorption and power-generation type strain deceleration strip has the advantages that the impact force and pulse energy lost when the vehicles pass the deceleration strip can be recycled by the inner and outer structures of the deceleration strip in combination with the power transmission connecting rod mechanism and the speed changing gear system, the power generators convert the recycled energy into electric energy, the electric energy is stored in the storage battery to power the whole system, and the independence of the system is guaranteed; the inner and outer structures of the deceleration strip are combined with reset springs to form a three-layer structure with adjustable strip heights and slope and the effect of buffering, and vehicle damage caused by severe mechanical vibration is alleviated.
