The invention relates to a battery pack anti-collision beam structure. The structure comprises a front anti-collision beam, a rear anti-collision beam, a left anti-collision beam and a right anti-collision beam. A left connection beam is arranged at the front end of the upper surface of the left anti-collision beam, and a right connection beam is arranged at the front end of the upper surface of the right anti-collision beam; the left end of the front anti-collision beam is fixedly connected with the upper end of the left connection beam, and the right end of the front anti-collision beam is fixedly connected with the upper end of the right connection beam; the included angle between the axis of the left connection beam and the normal which is simultaneously perpendicular to the front anti-collision beam and the left anti-collision beam is smaller than 45 degrees; the axis of the right connection beam is simultaneously perpendicular to the front anti-collision beam and the right anti-collision beam. By means of the structures of the front anti-collision beam, the rear anti-collision beam, the left anti-collision beam and the right anti-collision beam, the mechanical strength of a battery pack anti-collision beam is guaranteed; due to the angle design of the left connection beam and the structural design of the right connection beam, the battery pack anti-collision beam has a certain buffering effect on collision force, and the safety of a battery pack is ensured.
