The invention discloses a single-wheel strut landing gear structure for a large wingspan lightweight unmanned aerial vehicle. The landing gear structure comprises a landing gear upper part, a landing gear lower part and an aircraft wheel component, wherein the landing gear upper part comprises a strut, a connecting sleeve, an automatic centering and pull wire sleeve, a connecting flange, a connecting inner liner and a top end inner liner; the strut is of a thin-wall round pipe structure completely made of composite material, the upper part of the strut penetrates through the hollow connecting flange connected with an aircraft body, the connecting inner liner is arranged on the inner wall of the connecting flange, the top end inner liner sleeves the top end of the strut, and the bending moment borne by the landing gear is transferred to the aircraft body by using the connecting inner liner and the top end inner liner. The landing gear structure disclosed by the invention is connected with the aircraft body by using the two-point connection of the thin-wall flange and the top end inner liner, and due to the design of connecting the strut and an aircraft wheel connector by using standard parts, convenience of mounting, dismounting, maintenance and transportation of the landing gear structure can be greatly improved.
