The invention relates to the technical field of spaceflight satellites, in particular to a spaceflight satellite integrated special-shaped unfolding structure which comprises a satellite, a first unfolding mechanism, a second unfolding mechanism and a cover plate, a motor is arranged on the satellite, the first unfolding mechanism comprises a first limiting plate, a first antenna panel and a first push rod, the first limiting plate is installed on the satellite, a spring is installed above the first limiting plate, and the first antenna panel is installed on the first push rod. The first antenna panels are located below the first limiting plate, the four first antenna panels are stacked downwards, each first antenna panel comprises a first T-shaped limiting protrusion, a T-shaped limiting groove and a first limiting hole, the first T-shaped limiting protrusion is located at one end of a body of the first antenna panel, and the T-shaped limiting groove is located at the other end of the body of the first antenna panel. The T-shaped limiting groove is matched and connected with the T-shaped limiting bulge I on the other antenna panel I, and the limiting holes I are positioned on two sides of the T-shaped limiting groove; the antenna panel is unfolded through cooperation of the satellite, the first unfolding mechanism and the second unfolding mechanism, the outer envelope area of the satellite can be reduced, and then the launching cost is reduced.

    本发明涉及航天卫星技术领域,具体为一种航天卫星一体式异形展开结构,包括卫星、展开机构一、展开机构二、盖板,所述卫星上设有电机,展开机构一包括:限位板一、天线面板一、推动杆一,限位板一安装在卫星上,限位板一上方安装弹簧,天线面板一位于限位板一下方,天线面板一向下共堆叠四个,天线面板一包括:T形限位凸起一、T形限位槽、限位孔一,T形限位凸起一位于天线面板一主体一端,T形限位槽位于天线面板一主体另一端,T形限位槽与另一块天线面板一上的T形限位凸起一配合连接,限位孔一位于T形限位槽两侧;本发明通过卫星、展开机构一、展开机构二之间的配合实现天线面板的展开,可以减小卫星的外包络面积,进而减少发射成本。
