The invention belongs to the technical field of automobile safety, and particularly relates to a linear rotation compression energy absorption automobile anti-collision protection mechanism which comprises a main beam and a linear rotation compression energy absorption device connected to the main beam. The linear rotating compression energy absorption device comprises an energy absorption box body, a base, a detachable combined lead screw, a touch pressing piece, a rotating scraper and an internally-attached comprehensive energy absorption sleeve piece, the base is arranged at the bottom of the energy absorption box body, and the detachable combined lead screw is vertically installed in the middle of the top of the base. A traditional energy absorption box wrinkle deformation crumple energy absorption structure is optimized into a linear rotating compression energy absorption structure which takes wrinkle deformation energy absorption as an auxiliary mode and provides energy generated by longitudinal compression for rotating mechanical power, and longitudinal compression energy is transversely transferred through rotating mechanical power spiral rotating compression. Compared with an existing energy absorption box, the collision energy absorption amount and absorption efficiency of the energy absorption box are improved to a great extent, and the personal safety and the automobile body safety are better guaranteed.
