Problems solved by technology

In addition, the current large-load non-pyrotechnic unlocking device can be reused only through special tooling or manual operation, so additional related mechanisms are added to achieve multiple reuses on orbit, and the launch weight index is lost. The increased mechanism also has a certain impact on reliability, so there are many deficiencies in the current non-pyrotechnic separation mechanism

Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] refer to figure 1 , shows a schematic structural view of the self-recovery trigger mechanism in the locked state according to the embodiment of the present invention.

[0027] The self-restoring trigger mechanism provided by the present invention can be used not only as a separate small-load connection and separation device, but also as a trigger mechanism of a large-load load separation mechanism. The specific application scenarios are not limi...

Abstract

The embodiment of the invention discloses a self-restoration triggering mechanism. The mechanism is formed by connecting a casing, a runner, a Kevlar rope, a reset spring, a memory alloy wire, a pullblock, an electrode, a second-stage swing arm reset torsion spring, a second-stage swing arm, a limiting pin, a limiting arm torsion spring, a limiting arm, a first-stage swing arm reset torsion spring and a first-stage swing arm according to a preset connection relationship. When the self-restoration triggering mechanism works, the self-restoration function can be achieved for reuse without relying on other tools, and therefore the triggering mechanism is reused.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a self-restoring trigger mechanism. Background technique [0002] There are many connection and separation links in space missions, and the functional mechanism to realize the unlocking and separation between spacecraft components is called the connection and separation mechanism, which is a key component in various connection and separation systems. The connection and separation mechanism must not only ensure the separation during the launch phase, but also ensure the reliable connection, separation and release of the spacecraft and its payload during the orbital operation phase. At present, pyrotechnic separation technology is widely used, but the pyrotechnic separation device has strong separation impact, obvious additional pollution, non-reusable and insufficient testability, which seriously limits its application to precision loads such as cameras, flexible antennas, and laser equipme...
