Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the drawings.

[0041] The existing spacecraft is provided with a main optical engine platform and an on-orbit replaceable unit 5. The so-called on-orbit replaceable unit 5 is a relatively independent functional module or small load that provides a certain function for the spacecraft. In the present invention These functional modules or small loads are collectively referred to as the on-orbit replaceable unit 5, and the present invention is mainly for plug-in replacement of the on-orbit replaceable unit 5.

[0042] Such as figure 1 with figure 2 As shown, the on-track maintenance quick-connect system based on the dual-conjugate cam assist principle of the present invention mainly includes: left assist mechanism 1, left assist lug 2, right assist mechanism 3, right assist lug 4, fast Socket 6, quick-connect socket mounting plate 7, quick-connect plug 8, quick-connect plug mounting plate 9, 2 ...

Abstract

An on-orbit maintenance quick connection system based on a bi-conjugate cam assistance principle relates to the field of on-orbit maintenance in aviation and spaceflight. The problem on how to complete an on-orbit maintenance process of an on-orbit replaceable unit with large plugging and unplugging force quickly and assist astronauts is solved. The on-orbit maintenance quick connection system includes a quick jack mounting plate on which a quick jack and positioning guide pins are fixed, an on-orbit replaceable unit, a quick socket mounting plate which is fixed to the lower end of the on-orbit replaceable unit, two assistance support lugs which are respectively fixed to the left and right sides of the lower end of the on-orbit replaceable unit and are symmetric about the center of mass of the on-orbit replaceable unit, and two assistance mechanisms which are respectively fixed to the two sides of the quick jack mounting plate. The two assistance mechanisms have a one-to-one correspondence relationship with the two assistance support lugs. When the two assistance mechanisms are shifted, the two assistance support lugs are driven to make the quick jack plugged into a quick socket. The two assistance mechanisms rotate 90 degrees simultaneously to complete plugging and unplugging of the on-orbit replaceable unit. The on-orbit maintenance quick connection system has the advantages of simple structure, low weight, small size and easy installation.

Description

Technical field [0001] The invention relates to the technical field of on-orbit maintenance in aerospace, in particular to an on-orbit maintenance quick-connect system based on the principle of double conjugate cam assist. Background technique [0002] With the rapid development of aerospace technology, space activities have become more frequent, the number of spacecraft in orbit is increasing, the structure and composition of spacecraft have become increasingly complex, and their performance and technical level have also been continuously improved. However, due to the impact of launch costs and the objective environment, spacecraft are rarely maintained, maintained, and upgraded such as ground equipment. Moreover, the space environment in which the spacecraft is located is complex and harsh, and the spacecraft often has functions in its mission. In the case of failure, the loss is huge. Therefore, how to ensure the long-lasting and stable operation of spacecraft in the space en...
