Embodiment Construction

[0029] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Such as Figure 1 to Figure 13As shown, the double-layer deployable antenna mechanism based on the diamond-shaped expandable unit scissor connection of the present invention includes a rhombic expandable unit and a scissor rod 2. The specific structure and connection relationship are as follows: the diamond-shaped expandable unit includes the first A diamond-shaped expandable unit 1 and a second diamond-shaped expandable unit 3, the first rhombus-shaped expandable unit 1 includes a first-layer expandable unit I, a second-layer expandable unit III and a support member II; Unit I is composed of a first base 1-1, a bracket rod, a hinge and a small rhombus unit P1. The first base 1-1 is a double-layer pentagonal base, and the upper and lower layers of the base are pentagonal bases. There is a pin seat on each side, and the ...

Abstract

A two-layer deployable antenna mechanism based on diamond deployable element scissors is provided. A first diamond deployable unit is connected to a second diamond deployable unit through a shearing fork bar, the shearing fork bar includes a first shearing fork bar and a second shearing fork bar, the first diamond-shaped deployable unit includes a first layer of deployable units, a second layer ofdeployable units and a support member, the first-layer deployable unit is composed of a first frame, a bracket bar, a hinge and a small diamond unit, and the support member includes a first group ofsupport members, a second group of support members, a third group of support members and a fourth group of support members, and the support members support the first-layer deployable unit and the second-layer deployable unit up and down. The mechanism has the characteristics of large folding ratio, large structural rigidity, good stability, low manufacturing cost and few component types, and is suitable for the field of space satellite plane transmitting antenna and the like.

Description

technical field [0001] The invention relates to the field of space expandable mechanisms, in particular to a double-layer expandable antenna mechanism based on rhombic expandable unit scissor connection. Background technique [0002] With the vigorous development of the aerospace industry, the exploration of outer space is gradually deepening. It is necessary to carry different spacecraft support frames to outer space to perform corresponding tasks. However, due to the limited space for rocket transportation, this requires the organization to be in a folded or folded state. It is fixed in the transport load compartment, and then unfolded into a mechanism after entering the predetermined trajectory, so the mechanism can be deployed to become a significant feature of many spacecraft or large-diameter antennas. At present, many space folding mechanisms can be deployed through a combined array of folding units or topological composition. [0003] Chinese patent 201710876469.5 d...
