The invention relates to an automatic unfolding mechanism and an extensible satellite, and relates to the technical field of space, a plurality of unfolding trays of the automatic unfolding mechanism are arranged in an up-down stacked mode, the unfolding tray at the uppermost end is fixedly connected with a main frame, the other unfolding trays can be connected to the main frame in a coaxial horizontal rotation or same-direction sliding mode, and a vertical track surface is arranged on the upper side of each unfolding tray; a spring wheel is arranged between every two adjacent unfolding trays, the spring wheels are fixedly connected with the bottom faces of the unfolding trays above the spring wheels and are in rolling fit with the rail faces of the unfolding trays below the spring wheels, the rail faces firstly extend towards the outer side and then extend towards the inner side in the moving direction, and the tail ends in the moving direction are closer to the inner side than the initial ends. The excitation device is used for pushing the unfolding tray at the lowermost end. Only the excitation device is needed to excite the first unfolding tray, the spring wheels move along the corresponding bistable tracks to release potential energy, the potential energy in the follow-up unfolding trays can be released one by one, the potential energy release process is controllable in speed, small in buffering, and simple and reliable in structure.

    本发明涉及一种自动展开机构和可展卫星,涉及太空技术领域,自动展开机构的多个展开托盘上下层叠设置,最上端的展开托盘与主框架固定连接,其余展开托盘可同轴水平转动或同向滑动的连接在主框架上,并在上侧设有竖直的轨道面,相邻两个展开托盘之间设有弹簧轮,弹簧轮与其上方的展开托盘的底面固定连接,与其下方的展开托盘的轨道面滚动配合,轨道面沿移动方向先向外侧延伸再向内侧延伸,且沿移动方向的末端相比于初始端更靠近内侧,激励装置用于推动最下端的展开托盘。本发明只需要激励装置给第一个展开托盘一个激励,弹簧轮沿相应双稳态轨道移动释放势能,后续展开托盘中的势能就能逐个释放,势能释放过程速度可控、缓冲小、结构简单可靠。
