Embodiment Construction

[0031] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0032] The deployment locking mechanism based on the torsion spring provided by the present invention includes a frame 12, a rotating shaft 5, a torsion spring 6, a connecting piece 4, two locking rods 13, a slideway L1, and a slideway R9.

[0033] Such as image 3 , Figure 5 As shown, the main body of the connector 4 is a flange, and the two sides of the flange are symmetrically provided with protruding rods, and the flange is threadedly connected with the external expanded mechanism. Such as Figure 6 As shown, a boss is provided along the normal direction of the flange, and the boss is provided with a through hole matched with the rotating shaft 5, and boss holes matched with the straight legs of the torsion spring 6 are evenly arranged along the outer circumference of the through hole. There are 16 boss holes in total. The connecting lines of the ...

Abstract

The invention discloses an unfolding locking mechanism based on a torsion spring. With the torsion spring as a power source, the mechanism is unfolded and locked. By adjusting the mounting position ofthe torsion spring, the unfolding locking mechanism based on the torsion spring can be not only used as the power source but also have a damping effect; and the unfolding locking mechanism based on the torsion spring has the advantages of small volume, light weight and high reliability.

Description

technical field [0001] The invention relates to the technical field of aircraft mechanisms, in particular to a passive unfolding locking mechanism using a torsion spring as a power source in a microgravity environment. Background technique [0002] With the rapid development of space vehicle technology, its structure is becoming increasingly complex and its functions are increasing. Various mechanisms are required to complete various tasks. The mechanism has become an indispensable and important part of modern space vehicles. At the same time, due to the The carrying space of the equipment is limited, so the mechanism is required to be small in size, light in weight and high in reliability. The development of the mechanism can broaden the configuration design of the spacecraft and realize complex and high-precision motion functions, which has broad application prospects. [0003] In the prior art, when scroll springs are used to provide the deployment power required by the ...
