The invention relates to a scissor type unfolding mechanism which comprises a top short rod assembly, scissor type stage group rod piece units, a bottom supporting rod assembly, a driving unit assembly and an unfolding in-place indicating switch, the unfolding mechanism is connected with an unfolded object through the top short rod assembly, and the multiple stages of scissor type stage group rod piece units are connected through hinge shafts to form a multi-stage unfolding mechanism. The long rods of the multiple stages of unfolding mechanisms are connected in sequence; the bottom supporting rod assembly is connected with the driving unit assembly, the driving unit assembly drives the bottom supporting rod assembly to achieve unfolding and folding of the unfolding mechanism, after the unfolding mechanism is unfolded, a stable triangular structure is formed through the bottom supporting rod assembly, the scissor type stage group rod piece units and the limiting devices, the structural rigidity is improved, and the unfolding mechanism is controlled to be unfolded.
本发明涉及一种剪刀式展开机构,顶部短杆组件、剪刀式级组杆件单元、底部支撑杆组件、驱动单元组件和展开到位指示开关,展开机构通过顶部短杆组件与被展开物连接,多级剪刀式级组杆件单元通过其中铰链轴连接形成多级展开机构,多级展开机构的长杆依次连接;底部支撑杆组件与驱动单元组件连接,驱动单元组件驱动底部支撑杆组件实现展开机构的展开和收拢,本发明展开机构展开后通过底部支撑杆组件、剪刀式级组杆件单元和限位装置形成稳定三角形结构,提高结构刚度,控制展开机构展开。
