The invention discloses a fixing and unfolding device for a large-size out-of-satellite antenna of a pico-nano satellite. The device comprises a satellite cabin plate, a supporting seat, an unfolding and limiting hinge, a hot knife rope and a connecting rod mechanism, the main supporting seat is fixed on a satellite cabin plate, the connecting rod mechanism is installed on the satellite cabin plate through the unfolding and limiting hinge, the connecting rod mechanism is locked on the supporting seat through the hot knife rope, and the hot knife rope is fused through an unlocking hot knife on the connecting rod mechanism to unlock the connecting rod mechanism. The device is simple in structure, convenient to disassemble and assemble, reliable in operation, low in development cost, short in development period, capable of adapting to high and low temperature environments, capable of being unfolded at multiple angles and capable of effectively reducing launching cost and improving on-orbit communication and ground data transmission efficiency.

    本发明公开了一种皮纳卫星大尺寸星外天线固定及展开装置,该装置包括卫星舱板、支撑座、展开及限位铰链、热刀绳和连杆机构;主支撑座固定在卫星舱板上,连杆机构通过展开及限位铰链安装在卫星舱板上,热刀绳将连杆机构锁紧在支撑座上,通过连杆机构上的解锁热刀熔断热刀绳解锁连杆机构。本发明结构简单,拆装方便,运行可靠,研制成本低,研制周期短,能适应高低温环境,多角度展开,可以有效降低发射成本及增加在轨通信和对地面数据传输效率。
