Embodiment 1

[0034] Such as Figure 1-Figure 6 As shown, a foldable and unfoldable space platform in this embodiment includes a turntable 1 and several support frames 2, and several support frames 2 respectively adopt a foldable structure and are arranged around the periphery of the turntable 1. Two adjacent support frames 2 are hinged to each other; one end of several support frames 2 is respectively connected to the peripheral side of the turntable 1 through the memory alloy 3, and the support frame 2 is opposite to the turntable by turning on and off the power through the memory alloy 3 1Turn to preset position.

[0035] The memory alloy 3 can be connected together with the support frame 2 and the turntable 1 by thermoplastic means, the memory alloy 3 can provide a single-degree-of-freedom deformation driving force, when the support frame 2 needs to be opened, the memory alloy 3 is continuously energized, and the memory alloy 3 sheets Open, drive the support frame 2 to keep unfolding, ...

Embodiment 2

[0039] Such as Figure 1-Figure 6 As shown, a foldable and unfoldable space platform in this embodiment includes a turntable 1 and several support frames 2, and several support frames 2 respectively adopt a foldable structure and are arranged around the periphery of the turntable 1. Two adjacent support frames 2 are hinged to each other; one end of several support frames 2 is respectively connected to the peripheral side of the turntable 1 through the memory alloy 3, and the support frame 2 is opposite to the turntable by turning on and off the power through the memory alloy 3 1Turn to preset position.

[0040] The memory alloy 3 can be connected together with the support frame 2 and the turntable 1 by thermoplastic means, the memory alloy 3 can provide a single-degree-of-freedom deformation driving force, when the support frame 2 needs to be opened, the memory alloy 3 is continuously energized, and the memory alloy 3 sheets Open, drive the support frame 2 to keep unfolding, ...

Embodiment 3

[0059] Such as Figure 1-Figure 6 As shown, a foldable and unfoldable space platform in this embodiment includes a turntable 1 and several support frames 2, and several support frames 2 respectively adopt a foldable structure and are arranged around the periphery of the turntable 1.

Abstract

The invention relates to a foldable and unfoldable space platform which comprises a rotary table and a plurality of supporting frames, the supporting frames are each of a foldable and unfoldable structure and annularly arranged on the peripheral side of the rotary table, and every two adjacent supporting frames are hinged to each other; one ends of the multiple supporting frames are connected to the peripheral side of the rotary table through memory alloy, and the supporting frames are made to rotate to preset positions relative to the rotary table through power-on and power-off of the memoryalloy. The exposed area of the space platform is obviously increased after the space platform is unfolded, the occupied area of the whole panel is relatively small in the recycling process, and the launching and recycling cost can be reduced; deformation driving force generated by on-off of the memory alloy is adopted to enable the supporting frame blades to rotate, and then all the supporting frame blades are driven to rotate relative to the rotary table, so that the structural weight can be reduced, the space is saved, and the system reliability is improved.

Description

technical field [0001] The invention relates to the technical field related to space loads, in particular to a foldable and unfoldable space platform applied to space exposure and planetary scientific sampling return experimental loads.
