Suspended sub-satellite connecting structure plate of main and sub-satellite double-satellite system

The invention provides a suspended sub-satellite connecting structure plate of a main and sub-satellite double-satellite system. The structure plate comprises a main-satellite side plate, sub-satellites and a separation unlocking mechanism. The sub-satellites are integrally suspended and are arranged on the main-satellite side plate through the separation unlocking mechanism, and the sub-satellites and the main-satellite side plate can realize on-orbit separation through the separation unlocking mechanism. In the invention, a connecting embedded part structure is designed on an outer side of asub-satellite structure frame; a problem of whole sub-satellite suspension type installation in the main and sub-satellite double-satellite system is solved; a sub-satellite bottom plate and the mainsatellite side plate can be fixedly mounted by the whole sub-satellite through the separation unlocking mechanism; and the sub-satellite is integrally suspended on the main satellite, the sub-satellite bottom plate and the ma
