A space-on-orbit replaceable module electromechanical-thermal integration interface device

Abstract

The invention provides a mechanical-electrical-thermal integrated interface device of a space on-orbit replaceable module, and belongs to the technical field of space on-orbit replaceable modules. Thedevice comprises a driving end module and a driven end module, the driving end module comprises a round shell, a transmission shaft, a locking clamping jaw, a heat exchange output face, an electric connector inserting opening, a guide conical rod, a vision camera preset groove, a set screw, a gear transmission set and a center shaft, and the driven end module comprises a guide conical hole, a heat exchange receiving face, an electric connector receiving groove and a center locking rod. According to the invention, reliable butt joint and axial approaching locking of the on-orbit replaceable module under the condition of large tolerance can be realized; therefore, mechanical-electrical-thermal integrated cooperative butt joint of mechanical connection separation, energy communication transmission and heat conduction is completed, the locking mechanism which is flat and compact in layout provides a large available internal space for the module to a certain extent, and the effective loadof the module is improved.

Description

technical field [0001] The invention relates to the technical field of space-on-rail replaceable modules, in particular to a space-on-rail replaceable module electromechanical-thermal integration interface device. Background technique [0002] In recent years, due to the advancement of technologies such as space robots and space rendezvous and docking, autonomous on-orbit services have become a reality. The autonomous on-orbit service technology can realize on-orbit services such as module replacement and upgrade of the target spacecraft, but it also puts forward higher requirements on the serviceability of the target spacecraft. [0003] Modular spacecraft for on-orbit services has gradually become a research hotspot in the international aerospace field. This kind of modular spacecraft usually requires standard and unified mechanical, energy, Communication, thermal control and other interfaces, its modules are replaceable, easy to operate, plug and play and other character...

AI Technical Summary

Problems solved by technology

[0004] Before the launch of the spacecraft, a series of measures to improve reliability should be taken, such as higher requirements for components, redundant design, selection of relatively mature components and mature technologies, etc. The redundant locking ability of the structure, although the reliability is improved , but to a certain extent, the complexity of the interface is increased, which in turn causes the weight of the module to increase, which greatly reduces the available space inside the module
