1. A spatial large-stroke compliant hinge with hybrid structure, the hinge comprising a rectangular planar unit connected to a crossed-shaped planar unit, the rectangular planar unit used to realize an out-of-plane torsion function, the rectangular planar unit formed by a rectangular structure surrounded by two flexible long straight beams and two flexible short straight beams, wherein a center of a first long straight beam is a fixed section, two ends of the first long straight beam are a first torsion section; and a center of a second long straight beam is a second torsion section, two ends of the second long straight beam are a third torsion section, the cross-shaped planar unit used to realize an in-plane rotation function, the crossed-shaped planar unit is a crossed-shaped structure formed by two flexible and intersecting straight beam thin sheets, an outer side of the crossed-shaped structure and the second torsion section connected by an external connection to form a triangular structure with a high stiffness and a stable structure, the triangular structure used to connect the crossed-shaped structure and the rectangular structure, and to transmit torque.
