A standardized modular cube star unit and method

Abstract

The invention discloses a standardized modular cubesat unit and method, and belongs to the technical field of micro-nano satellites. The unit comprises a plurality of cubesat standard modules, the modules are assembled in a bidirectional direct insertion mode through a standard four-in-one connecting device, and mechanical connection, power transmission, data interaction and heat energy conductionbetween the adjacent modules are achieved. The 'female-male-female' design enables the cubesat module to be a female interface, any two modules can be assembled, and the symmetrical design layout enables the assembly direction to be flexible and diverse. The cubesat module is mechanically connected and installed in the through hole in the structural frame, the power supply, the data and the heattransfer interface are installed on the surface of the module, the internal space of the module is not occupied, a standard cubesat CSKB board is compatible, and the basic attributes of the cubesat are reserved. Reliable connection of the cubesat modules is guaranteed through a positioning pin and barb structure mechanical interface, and reliable conduction between the cubesat modules is guaranteed through a power supply, data and heat transfer interface in an elastic contact mode.

Description

technical field [0001] The invention belongs to the field of micro-nano-satellite technology, and relates to a standard cubesat modular assembly structure including a mechanical-power supply-heat transfer-data four-in-one interface, in particular to a standardized modularized cubesat unit and method. Background technique [0002] CubeSat is a low-cost micro-nano satellite that adopts international common standards. It takes "U" (1U=10cm×10cm×10cm) as the basic unit, and can be expanded to larger structural units on this basis. Its standardized structure has developed The advantages of short cycle and low development cost are the main directions for the development of micro-nano satellites. In recent years, with the development of science and technology, the number and types of CubeSats launched have increased. If the traditional CubeSat board-level module assembly idea is still adopted, different units of CubeSats can be customized according to different launch tasks and loa...

Problems solved by technology

However, there are the following disadvantages: the structural size is too large, the standard module volume is 400mm×400mm×400mm, and the mechanical interface of the intelligent connection device is φ140mm×40mm; the intelligent connection device has many components and is heavy, which occupies the internal space of the satellite and reduces the payload of the satellite ;The mechanical interface of the intelligent connection device adopts motor-driven telescopic rotary coupling moving parts, which has a complex structure, increases potential failure risks, and reduces system reliability

However, there are the following disadvantages: in order to realize the rotary dovetail joint, the cell body shell needs to be designed into a special structural shape and occupy the internal space of the cell; the insertion and rotation locking of the connecting pin between the two cells needs to be precisely matched, and the assembly accuracy is high.

However, there are the following deficiencies: the electrical connection and thermal energy conduction between the cube star modules are not considered
