Embodiment Construction

[0027] Figure 1-Figure 7 It shows a preferred embodiment of the novel coiled extension arm provided by the present invention, which is sequentially and gradually unfolded.

[0028] Such as figure 1 As shown, the segmented and gradually unfolded coiled extension arm in this specific embodiment includes a locking and releasing mechanism 102 and an extension arm truss 101 , a storage tube 103 and an electromechanical transmission mechanism 104 connected in sequence. Wherein, the bottom of the extension arm truss 101 is fixedly installed on the storage tube 103, and the extension arm truss 101 is configured to be coiled and folded. The storage tube 103 is set to be able to store the extension arm truss 101 in the coiled and folded state; the locking and release mechanism 102 is arranged around the wall of the storage tube 103, which is used to realize the compression locking and extension arm when the extension arm truss 101 is in the folded state. Deployment release when the t...

Abstract

The invention discloses a coiling type telescopic arm capable of achieving segmental, sequential and progressive expanding. The coiling type telescopic arm comprises a locking and releasing mechanism, a telescopic arm truss, a collection barrel and a mechanical and electrical transmission mechanism, and the telescopic arm truss, the collection barrel and the mechanical and electrical transmission mechanism are connected in sequence. The telescopic arm truss is fixedly mounted in the collection barrel and arranged to be capable of being coiled and drawn back. The collection barrel is arranged to be capable of storing the telescopic arm truss which is coiled and drawn back. The locking and releasing mechanism is arranged around the barrel wall of the collection barrel and used for pressing and locking the expanded telescopic arm truss which is drawn back and expanding and releasing the telescopic arm truss in the rebounding and expanding process. The mechanical and electrical transmission mechanism is used for driving the telescopic arm truss and the locking and releasing mechanism. The telescopic arm is simple in structure, small in expanding impact and reliable, the top end of the arm is kept directional, the overall mass is low, rigidity is large, and the telescopic arm can be used for space-expandable antennas, solar cell arrays, solar sails, space platforms, detecting arm mechanisms and the like.

Description

technical field [0001] The invention relates to a high-precision extension arm, in particular to a coil-type extension arm that unfolds step by step in stages, which can be used in space extendable antennas, solar battery arrays, solar sails, space platforms, detection arm mechanisms, and the like. Background technique [0002] The space extension arm is the most basic type of space expandable structure. Its research is the earliest, the deepest, the most systematic, the technology is the most mature, and the application is the most extensive. However, the new type of extension arm is still an important direction of continuous exploration and research and development in various countries. The space extension arm is mainly a one-dimensional linear system, which is a slender tube, rod or frame (truss), and can be widely used in the deployment mechanism of large solar wings and large antennas. As the main unfolded load-bearing member, the spatial extension arm plays an importan...
