Abstract

The invention belongs to the technical field of on-orbit service, in particular to an on-orbit replaceable unit. The on-orbit replaceable unit with autonomous guiding and connecting functions is disclosed, and the technical scheme is that a passive plate is provided with a coarse guiding hole, a fine positioning hole and a locking screw hole therein; an active plate is provided with a coarse guiding rod and a fine guiding rod thereon; a locking assembly includes a locking shell and a locking rod sleeved therein; the locking rod is provided with a thread; male and female parts of an electricalconnector are respectively mounted on the passive plate and the active plate; and the active plate is mounted at the bottom of an equipment compartment, the locking assembly passes through the equipment compartment, and two ends of the locking shell are respectively connected with the active plate and an adapter. The on-orbit replaceable unit in the invention adopts the guiding way of the combination of coarse guiding and fine guiding, and has the advantages of large tolerance range and high guide precision. The connection interface in the invention adopts the thread form, the power is input by the adapter, and the advantages of fast connection and reliable connection are gained.

Description

technical field [0001] The invention belongs to the field of on-orbit service technology, in particular to an on-orbit replaceable unit. Background technique [0002] With the rapid development of space technology, the pace of human development and utilization of space is getting faster and faster, and space systems are becoming more and more complex and larger in scale. Due to the characteristics of high cost, high risk, and weight limitation of space missions, once it fails to enter orbit or a serious failure occurs after orbit, it will cause huge losses. Therefore, in order to recover as much as possible the loss caused by the failure or failure of the spacecraft and effectively protect the resources in the geostationary orbit (GEO), the spacecraft is required to have on-orbit service functions, such as completing on-orbit fuel filling and using the automatic load handling system to replace Tasks such as damaged components or replenishing consumables. It is of great sig...
