The invention discloses a deformable wing parallel guide rail distributed driving telescopic mechanism, and relates to the technical field of aviation equipment technologies. The problems that an existing high-speed aircraft deformation wing cannot meet the deformation and bearing requirements of the high-speed aircraft deformation wing, and the contradiction between the height of a small wing type structure and a high-reliability large-tolerance telescopic mechanism cannot be solved are solved. A distributed motor provides rotation driving input for a driving transmission mechanism, the inner side of a nut is spirally connected with a lead screw, and then a telescopic wing is driven to achieve telescopic movement; meanwhile, on one hand, the multiple double-dovetail-groove cantilever guide rail assemblies fixedly connected with the telescopic wing inner plate do follow-up motion; and on the other hand, the second-stage cantilever guide rail assembly fixedly connected with the telescopic wing inner plate conducts follow-up movement. According to the mechanism, high-reliability large-tolerance linear motion of the wing under a heavy load condition can be realized, the functions of deformation driving, supporting, motion guiding and the like are provided for the wing, and the aerodynamic performance of an aircraft under different flight conditions and flight tasks is improved.
