    Abstract: The disclosure relates to an anti-collision structure for an engineering machine, the engineering machine has a tail frame arranged at a rear end. The anti-collision structure comprises an anti-collision body that at least partially covers side walls and a rear end wall of the tail frame, wherein the anti-collision body is made of plates and configured to have a streamline shape and a hollow structure. The anti-collision structure of the disclosure can effectively avoid collision to the rear end or tail of the engineering machine when the machine climbs or reverses, which improves the overall strength and impact-resistance of the tail frame and the main frame of the engineering machine. In addition, the three-dimensional streamlined shape of the anti-collision structure matches the whole vehicle in style, adding highlights for the electric driver. The disclosure also relates to an engineering machine comprising the anti-collision structure.
