The invention provides a scissor type stretching mechanism based on spring pin locking for solar wing stretching, which comprises a synchronizing mechanism comprising a left synchronizing assembly and a right synchronizing assembly, the left synchronizing assembly is mounted on a left support seat, and the right synchronizing assembly is mounted on a right support seat; one end of the stretching mechanism is connected with the left synchronous assembly, the other end of the stretching mechanism is connected with the right synchronous assembly, and the left synchronous assembly and the right synchronous assembly are used for ensuring that the stretching mechanism can stretch to synchronously stretch the solar wing; the locking mechanism is arranged in the stretching mechanism and used for limiting the stretching mechanism not to stretch any more after the stretching mechanism reaches the limiting position in the stretching process. The left synchronous assembly and the right synchronous assembly are matched to enable the stretching mechanism to stretch so that the solar wing can stretch, and when the stretching mechanism stretches to a set position, the locking mechanism limits continuous movement of the stretching mechanism; the locking mechanism is driven in a passive mode, it is guaranteed that the stretching mechanism is kept in an unfolded stable state, and different from existing active driving, the mass of the solar wing is reduced.
本发明提供用于太阳翼伸展的基于弹簧柱销锁定的剪刀式伸展机构,包括同步机构包括左同步组件和右同步组件,左同步组件安装于左支架座上,右同步组件安装于右支架座上;伸展机构一端连接左同步组件,另一端连接右同步组件,左同步组件与右同步组件用以保证伸展机构能够进行伸展,使得太阳翼进行同步伸展;锁定机构设置于伸展机构中,用于限定伸展机构在展开过程中到达限定位置后不再进行伸展。左同步组件与右同步组件配合使得伸展机构能够进行伸展使得太阳翼进行伸展,当伸展机构伸展到设定位置时,锁定机构限定伸展机构的继续运动;锁定机构为无源驱动,保证伸展机构保持展开的稳定状态,区别于现有的有源驱动,减少了太阳翼的质量。
