Summary:The present invention relates to an electric vehicle frame structure. More particularly, the present invention relates to an electric vehicle frame structure, which comprises: a hollow tube having a hollow formed therein; a center solid portion provided in the hollow tube along the longitudinal direction of the hollow tube in a solid state without a hollow; and a rib portion connecting the center solid portion and an inner wall of the hollow tube.
