The invention discloses a front anti-collision beam structure for an automobile. The front anti-collision beam structure for the automobile comprises a beam used for bearing collision and two energy absorption devices fixedly connected to the two ends of the beam and extending backwards. Each energy absorption device comprises a cylindrical cylinder arranged in the front-back direction of the beam and a piston arranged in the cylindrical cylinder; the front end of each piston is fixedly connected with piston rods arranged in the length direction of the corresponding cylindrical cylinder; the end, away from the corresponding piston, of each piston rod penetrates the front end face of the corresponding cylindrical cylinder to the outer side of the cylindrical cylinder and is fixedly connected with a connecting board; each connecting board is detachably connected with the beam; the front end face of each cylindrical cylinder is provided with a pressure relief hole communicated with an inner cavity of the cylindrical cylinder; the position, corresponding to the pressure relief hole, of each piston is provided with a connecting hole; and the portions, on the two sides of the corresponding piston, of the cavity of each cylindrical cylinder can be communicated through the corresponding connecting hole. The front anti-collision beam structure is simple in structure and convenient to install, collision energy is consumed by extruding air, the collision force conversion capacity is improved, and meanwhile the safety of the automobile is improved.
