Specific-angle folding and unfolding mechanism for novel manned spaceship instrument panel

The invention relates to the technical field of space mechanisms, in particular to a specific-angle folding and unfolding mechanism for a novel manned spaces.The specific-angle folding and unfolding mechanism comprises a bulkhead, an instrument board, a rotating shaft assembly and a hydraulic rod assembly, the top end of the bulkhead is rotationally connected with the top end of the back face of the instrument board through the rotating shaft assembly, and a first rotating axis is formed; the middle upper part of the bulkhead is rotationally connected with the first end of the hydraulic rod assembly to form a second rotating axis; the bottom end of the back of the instrument panel is rotationally connected with the second end of the hydraulic rod assembly to form a third rotating axis; the first rotating axis, the second rotating axis and the third rotating axis are parallel to one another and are parallel to the back face of the instrument board. When the hydraulic rod assembly is compressed to the minimum,
