Low-impact energy storage pre-tightening hinge

Abstract

The invention relates to a low-impact energy storage pre-tightening hinge comprising a male hinge, a female hinge and an energy storage pre-tightening device, the male hinge and the female hinge are hinged through a rotating shaft assembly, the energy storage pre-tightening device is installed between the male hinge and the female hinge, the energy storage pre-tightening device comprises an energy storage part, a locking rod, a first check block and a second check block, and the energy storage part is connected between the first check block and the second check block; when the male hinge and the female hinge are in a folded state, the first check block is locked with the male hinge through a first elastic lock pin, and the second check block is locked with the locking rod through a second elastic lock pin. In the unfolding process of the male hinge and the female hinge, the female hinge abuts against one end of the locking rod and pushes the locking rod to move axially, and the locking rod drives the second check block to move towards the first check block and enables the energy storage part to store energy. When the male hinge and the female hinge are in an unfolded state, the female hinge and the locking rod are locked, the first check block and the male hinge are unlocked, the first check block and the locking rod are locked through the first elastic lock pin, the second check block and the locking rod are unlocked, and the second check block and the male hinge are locked through the second elastic lock pin.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a low-impact energy storage pre-tightening hinge. Background technique [0002] As a common and commonly used deployable mechanism in the aerospace field, hinges have a wide range of applications. For the space deployment mechanism, according to its deployment driving mode, it can be divided into passive drive and active drive. Among them, the passive drive forms mainly include scroll spring drive, torsion spring drive, constant moment spring drive and other forms. Due to the passive drive High reliability, ultra-simple and other advantages are widely used in aerospace folding and unfolding mechanisms. However, due to the relatively fast release of torque after the passive drive is deployed, the impact on the unfolded parts is relatively large after deployment, which seriously affects the accuracy of deployment. The high-stiffness hinge in the master's thesis "High Stiffness ...
