The invention discloses a rigid hinge type variable topological space polyhedron folding and unfolding mechanism. Comprising a first six-connecting-rod mechanism, a second six-connecting-rod mechanism, a third six-connecting-rod mechanism, a fourth six-connecting-rod mechanism, a fourth connecting frame rod, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a fifth connecting rod, a sixth connecting rod, a first connecting frame base, a first nine-connecting-rod mechanism, a second nine-connecting-rod mechanism, a first swing rod, a second swing rod and a third swing rod. The variable topological space polyhedral folding and unfolding mechanism comprises a first swing rod, a second swing rod, a third swing rod, a fourth swing rod, a fifth swing rod, a sixth swing rod, a seventh swing rod, an eighth swing rod, a three-degree-of-freedom composite hinge, a first connecting hinge and a second connecting hinge. The folding mechanism has the characteristics of large folding ratio, high reliability, strong stability, simple space folding process and the like. The method can be widely applied to the fields of large-diameter folding and unfolding antennas, large solar panel supports, spacecraft foundation frameworks and the like, and has high adaptability and practicability.
