The invention belongs to the technical field of automobile damping and energy storage, and particularly relates to an automobile damping and energy storage mechanism adapted for big impact force. Theautomobile damping and energy storage mechanism adapted for the big impact force includes a first baffle, a damping spring, a first nozzle, a damping shell, a second baffle, a second nozzle, a third nozzle, a fixing plate and so on; and a piston mechanism can move up and down in the damping shell when subjected to impact force, high-pressure inert gas in the damping shell enters an air motor to have a role through compressing of the piston mechanism, and the air motor drives an electric generator to generate electricity. Impactive energy is stored by the air motor and the electric generator when the automobile damping and energy storage mechanism adapted for the big impact force is under a normal running condition, and the purpose of rapidly absorbing impact force and rapidly declining damping can be realized; the structure is simple and compact, energy conservation is high, and the automobile damping and energy storage mechanism adapted for the big impact force has a better actual useeffect; and the problem that the inner structure of a damper is subjected to mechanical damage when the damper is subjected to momentary surging impact force is solved, the effect to protect the damper in an emergency can be performed, and the service life of the damper is prolonged.
