specific Embodiment approach 1

[0006] Specific embodiment 1: This embodiment is described in conjunction with Fig. 1, Fig. 2, Fig. 7, and Fig. 9. This embodiment consists of a base plate, a tether 2, a patch layer 3, a frame 4 that can be rigidly inflated and expanded, an inflatable pipe 5, The wire 6 and the control valve 7 are composed; the frame 4 is equipped with a substrate placed longitudinally along the frame, and the substrate and the frame 4 are fixedly connected by a tie 2; The left end of the inflatable tube 5 is installed in the support tube 4-1 that can be rigidized and inflated to expand on the frame 4 and is connected with the electric heating layer 4-1-1 of the support tube 4-1, and the left end of the inflatable pipeline 5 is installed in the support tube 4-1. In the tube 4-1, a control valve 7 is installed on the inflation pipe 5; the substrate is a rigid substrate or a flexible substrate 1-2.

specific Embodiment approach 2

[0007] Specific Embodiment 2: This embodiment is described in conjunction with Fig. 1 and Fig. 9. The rigid substrate of this embodiment is composed of a group of rigid substrate units 1-1-1 placed in parallel, and two adjacent rigid substrate units 1-1-1 Between and between the rigid substrate unit 1 - 1 - 1 and the frame 4 are fixedly connected by a tie 2 . The base plate is composed of a group of rigid base plate units 1-1-1, and this structure can keep the base plate flat and easy to fold. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0008] Specific Embodiment Three: This embodiment is described with reference to FIG. 2 and FIG. 9. The flexible substrate 1-2 of this embodiment is composed of at least one layer of polymer film or at least one layer of resin pre-impregnated fiber fabric. The flexible substrate 1-2 and the frame 4 are fixedly connected by frenulum 2. The flexible substrate 1-2 has the advantages of simple structure, light weight, high folding efficiency and small folding volume. In this embodiment, in order to maintain the flatness of the flexible substrate 1-2, the outer periphery of the flexible substrate 1-2 is connected to the tether 2 in the form of a catenary 1-2-1. Other components and connections are the same as those in the first embodiment.

Abstract

This invention relates to rigidity and charging extension plane frame supportive structure, which solves the current solar sailboard and plane antenna plane frame supportive structure mechanic extension and complex existence structure and bad reliability and low efficiency of folding. The frame rack is loaded with frame rack longitude baseboard, wherein, the baseboard and frame rack is connected through band; the baseboard upper end has sticking layer; the wire left end is fixed on frame rack supportive tube and is connected to supportive tube with electricity layer; the charging channel left end is fixed inside supportive tube with control valve.

Description

technical field [0001] The present invention relates to a deployable planar frame support structure for use on planar antennas or solar panels. Background technique [0002] Planar antennas and solar panels have been widely used in aircraft such as satellites, manned spacecraft, and space stations. The key to the normal operation of planar antennas and solar panels is whether their planar frame support structures can be deployed normally. The expansion of the traditional planar frame support structure mainly adopts a mechanical rigid structure. This expansion support structure is composed of many rigid components connected by a connecting mechanism, a control expansion mechanism and a locking mechanism, so it has a complex structure and is prone to failure in use. , poor deployment reliability, heavy overall weight, and low folding efficiency, especially the above-mentioned problems that exist in the deployment support structure of large-scale solar panels and planar antenna...
