The invention discloses a novel energy automobile battery protection damping mechanism which comprises a fixed base, a battery tank and a baffle plate, wherein a sealing tank and a piston cylinder are arranged between the fixed base and the battery tank; a horizontal main piston is arranged inside the sealing tank; a vertical main piston rod is fixedly connected with the upper end of the main piston; a rubber tube is communicated with the bottom inside the sealing tank; the rubber tube extends into the piston cylinder; the piston cylinder is connected inside a chute in a sliding manner; a support block is fixed at the upper end of a secondary piston rod; a protection plate is fixed on a side wall of the battery tank; and a vertical inner plate body is fixed on the protection plate. As the main piston rod is pushed downwards through the battery tank, the main piston is moved downwards, the air inside the sealing tank is compressed, downward movement of the battery tank is retarded, then collision is avoided, and a damping function is achieved; and moreover, the air is compressed inside the sealing tank, the secondary piston inside the piston cylinder is moved upwards, then the support blocks contacts a pressing block, the battery tank is supported, the battery tank can be conveniently recovered, and the damping effect is enhanced.
