The invention relates to a pressing and releasing mechanism for a satellite solar panel. The pressing and releasing mechanism is arranged through cooperation of a first metal connecting piece, a second metal connecting piece, shape memory alloy, a heating wire, a protection pipe and a metal spring. The shape memory alloy can be heated through a heating wire to be deformed into a linear structure from a bent structure and separated from the second metal connecting piece, and the metal spring drives the solar panel to be released and unfolded. The pressing and releasing mechanism for the satellite solar panel can well achieve high-rigidity connection of the solar panel and facilitate unlocking and unfolding of the solar panel, and has the advantages of a simple structure, low power consumption, good reliability, good universality, good sensitivity and the like.
本发明涉及一种用于卫星太阳帆板的压紧释放机构,该压紧释放机构通过第一金属连接件、第二金属连接件、形状记忆合金、加热导线、保护管和金属弹簧相配合设置,可通过加热导线对形状记忆合金加热使其由弯折结构形变为直线型结构,脱离第二金属连接件,金属弹簧驱动太阳帆板释放展开。该用于卫星太阳帆板的压紧释放机构能够很好地实现对太阳帆板的高刚度连接且便于完成太阳帆板的解锁展开,具有结构简单、功耗低、可靠性好、通用性好、灵敏度好等优势。
