The invention provides a pressing and releasing mechanism of a multi-subarray deployable planar antenna. The pressing and releasing mechanism comprises a mounting bottom plate, an antenna pressing plate, an initiating explosive device cutter, an elastic piece, a wedge-shaped pressing block, a matching pressing block and a plurality of pressing taper sleeve assemblies. And a panel antenna mounting position is arranged on the mounting bottom plate. The pressing and releasing mechanism has a locking state and a releasing state; when the pressing and releasing mechanism is in a locked state, the purposes of pressing the panel antenna and keeping the panel antenna in a folded state are achieved by tightening a pressing rod of the initiating explosive device cutter; when the pressing and releasing mechanism is in a releasing state, a pressing rod of the initiating explosive device cutter is damaged, the antenna pressing plate rotates around the mounting bottom plate under the action of the elastic piece, and the multi-subarray deployable planar antenna is in an unfolding state. The pressing and releasing mechanism provided by the invention is stable in structure, can fold and press a plurality of sub-plates, and has very high adaptability to a satellite adopting a flat plate type antenna payload at present.
本发明提供了一种多子阵可展开平板天线的压紧释放机构,包括安装底板、天线压紧板、火工品切割器、弹性件、楔形压块、匹配压块以及多个压紧锥套组件;所述安装底板上设置有平板天线安装位。所述压紧释放机构有锁定状态与释放状态;当所述压紧释放机构处于锁定状态时,本发明通过拧紧火工品切割器所具有的压紧杆以达到对平板天线压紧及保持折叠状态的目的;当所述压紧释放机构处于释放状态时,所述火工品切割器所具有的压紧杆被破坏,所述天线压紧板在所述弹性件的作用下绕所述安装底板转动,所述多子阵可展开平板天线处于展开状态。本发明提供的压紧释放机构结构稳定、可收拢压紧多块子板,对于目前采用平板式天线有效载荷卫星具有很高的适应性。
