Technical Field

The invention relates to a transmission mechanism, in particular to a dynamic sculpture mechanism which is driven by a single motor to enable the whole of each branched chain to rotate around a fixed point in a point-symmetric motion mode, further enable the whole tail end of a thin rod of each branched chain to move in a curve with a specific track in a point-symmetric motion mode, and achieve the decomposition and recombination of a certain object so as to present different artistic effects.

Background

The traditional transmission mechanism has relatively single structural form and function and relatively few applications in the field of art. The invention is based on a 2R open chain mechanism, and a transmission mechanism in a flower-shaped novel structural form is constructed by arranging each chain wheel, each chain and each branched chain in a concentric circle manner. The invention realizes the rotation around the fixed point of each branch chain in a point-symmetric motion mode through the transmission of the chain and the chain wheel driven by a single motor, and further pushes the synchronous belt wheel on the branch chain to drive so as to realize the rotation around the fixed point of the slender rod relative to the branch chain. Under the transmission mode, the tail end of each branched chain slender rod integrally realizes specific track curvilinear motion in a point symmetry mode, and the objects connected with the branched chain slender rods move in the same track curvilinear motion, so that the decomposition and recombination of the objects are realized, and different combined artistic effects are presented.
