Abstract

The invention discloses a space deployable mechanism designed on the basis of a posterior wing deployable mechanism of dermaptera insect earwigs. The space deployable mechanism is applied to a reflector of a satellite antenna and structurally comprises a first-grade rod set, a second-grade rod set, a third-grade rod set, a supporting rod set, a push-pull rod set, a combined hinge mechanism and a polyester film. End portions of rods in the first-grade rod set are sequentially connected through hinges. The second-grade rod set comprises rods and gears, and the gears are connected with the second-grade rods and then connected with the first-grade rods. Rods in the third-grade rod set are connected with the rods in the second-grade rod set through supporting rods. The rods in the first-grade rod set are driven so that the whole mechanism can be deployed. By the adoption of the space deployable mechanism, controllable folding and deployment of the satellite antenna of a spacecraft can be achieved, and the space deployable mechanism has the beneficial effects that the containing ratio is relatively large, and meanwhile a carbon fiber material is selected and used, so that the whole space deployable mechanism is small in weight, high in strength, good in stability and the like.

Description

[0001] Technical field: [0002] The invention relates to a space deployable mechanism, in particular to a space deployable mechanism designed based on the rear wing deployment mechanism of the dermatopteran earwig, which can meet the needs of the aerospace technology field for a mechanism with a high storage ratio, and belongs to the aerospace technology field. [0003] Background technique: [0004] The invention is inspired by earwigs of the order Dermatoptera. This insect has the characteristics of fast wing spreading speed, light weight, high storage ratio and stable flight, and this advantage is exactly what is needed in the field of aerospace technology. In recent years, with the development of space science and the advancement of aerospace technology, large-scale space deployment mechanisms have been used more and more. Due to the limitation of the space of the space launch vehicle carrier cabin, the mechanism is in a folded state when launching, and fully unfolded after...
