The invention discloses an over-constrained modular deformation wing skeleton mechanism based on Waterbomb creases, which belongs to the technical field of aerospace and comprises a plurality of wing ribs, a plurality of transverse deformation modules and a plurality of supporting ribs. Modular expansion is achieved through the over-constrained transverse deformation module, the mechanism has the beneficial effects of being stable in structure, easy to drive and the like, and the production difficulty and the complexity of the mechanism are reduced through modularization; a paper folding theory is applied to the design of a deformation wing framework mechanism, a paper folding mechanism has structural rationality and shape variability, and multi-dimensional continuous deformation can be realized by taking a paper folding unit as a basic module of a deformation mechanism in combination with a deformation mode required by a deformation wing; according to the deformable wing skeleton mechanism, sweepback deformation, up-down bending deformation along the wingspan and sweep-bending coupling deformation of the wing can be achieved, and the aerodynamic configuration of the aircraft wing tends to be optimal; the adopted over-constrained transverse deformation module has the characteristics of large bearing capacity and high rigidity, and the rigidity of the deformation wing framework mechanism is greatly improved.
