The invention discloses a light electric steering engine anti-impact protective shell based on a three-dimensional rotating lattice structure. The light electric steering engine anti-impact protective shell comprises a steering engine shell body and an anti-impact protective layer embedded into the steering engine shell body. The steering engine shell body comprises an upper cover and a base; the anti-impact protective layer is manufactured by adopting a three-dimensional lattice structure; the unit cells of the three-dimensional lattice structure of the anti-impact protective layer embedded in the upper cover and the base adopt different rotation angles, so that the relative density and the energy absorption capacity of the three-dimensional lattice structure in the base are larger than those of the three-dimensional lattice structure in the upper cover. The arrangement structure and the relative density adjustability of the lattice structure of the anti-impact protective layer can be realized through three-
