1. a kind of foldable spherical structure, which is characterized in that can will be foldable by relative motion each other including sixSpherical structure is folded into the folding unit and first datum plane of flat state by spatiality;

  • Six fold unitSize is incremented by successively, and respectively first, which folds unit, the second folding unit, third, folds unit, the 4th folding unit, the 5th foldingFolded unit, the 6th fold unit;

    The first folding unit, the second folding unit, the 5th folding unit, the 6th folding unit are set at same positionTie point there are three putting, respectively the first tie point, the second tie point and third tie point;

    Unit, the are folded described firstTwo-fold unit, the 5th are folded in any folding unit of unit, the 6th folding unit, first tie point, the second connectionPoint, third tie point are located on same circle or on two or three concentric circles, and first tie point and third connectContact is on the straight line in the excessively described circle of same or the concentric circles center of circle, first tie point, the second tie point and the circleOr the angle of concentric circles circle center line connecting is known as the first angle;

    The third folds unit, the 4th folding unit is provided with four points of connection, respectively first at same positionTie point, the second tie point, third tie point, the 4th tie point;

    Any of unit, the 4th folding unit is folded in the thirdIt folds in unit, first tie point, the second tie point, third tie point, the 4th tie point are located on same circle or positionIn two either three either on four concentric circles first tie point and the 4th tie point in the excessively described circle of same orOn the straight line in the concentric circles center of circle, second tie point, the first tie point and the circle or the angle of concentric circles circle center line connectingIt is identical with the angle of the circle or concentric circles circle center line connecting with third tie point, the 4th tie point, and with first angleSize is identical;

    First tie point of the first folding unit and the third tie point of the described second folding unit pass through the first revolute pairConnection, the third tie point of the first folding unit and the first tie point of the described second folding unit pass through the second revolute pairConnection, the 4th tie point that the third folds the first tie point and the described 4th folding unit of unit pass through third revolute pairConnection, the first tie point that the third folds the 4th tie point and the described 4th folding unit of unit pass through the 4th revolute pairConnection, the first tie point of the 5th folding unit and the third tie point of the described 6th folding unit pass through the 5th revolute pairConnection, the third tie point of the 5th folding unit and the first tie point of the described 6th folding unit pass through the 6th revolute pairConnection;

    First revolute pair, the second revolute pair, third revolute pair, the 4th revolute pair, the 5th revolute pair and the 6th revolute pairAxis in first datum plane, and meet at same point and be known as the first intersection point;

    The third tie point that second tie point of the first folding unit folds unit with the third passes through the 7th revolute pairConnection, the second tie point of the second folding unit and the third tie point of the described 4th folding unit pass through the 8th revolute pairConnection, the second tie point that the third folds the second tie point and the described 5th folding unit of unit pass through the 9th revolute pairConnection, the second tie point of the 4th folding unit and the second tie point of the described 6th folding unit pass through the tenth revolute pairConnection;

    7th revolute pair, the 8th revolute pair, the 9th revolute pair and the tenth revolute pair axis meet at described first and hand overPoint.
