Abstract

The invention provides a rotary locking mechanism. The mechanism comprises a sliding block assembly, a rotary shaft assembly, a rotary cylinder assembly, a mounting assembly, a cam assembly and a locking assembly used for limiting movement of the rotary shaft assembly, wherein the rotary shaft assembly drives and controls the cam assembly to move; one end of the cam assembly is rotationally connected to the sliding block assembly, and the end, away from the sliding block assembly, of the cam assembly is rotationally connected to the mounting assembly; and the sliding block assembly is arranged on the rotary cylinder assembly in a sliding mode, and the rotary cylinder assembly is rotationally arranged on the mounting assembly. The locking mechanism may be suitable for rotary mechanisms of various sizes, a large-bearing, high-rigidity, high-stability and high-flexibility fixing mode is provided for locking of a space rotating mechanism, and the locking mechanism has high universality.

Description

technical field [0001] The invention relates to the technical field of spacecraft, in particular to a rotation locking mechanism. Background technique [0002] As the contradiction between the requirements of multi-function and large size of the spacecraft and the volume limit of the payload compartment of the vehicle becomes more and more acute, the spacecraft needs to use a large number of unfolded structures, that is, it is folded before entering orbit to reduce the envelope, and unfolded after entering orbit. Into the working state to effectively expand the function of the spacecraft. In order to complete the unfolding function of some large structures, this type of unfolding structure requires a rotating mechanism to unfold. Therefore, it must be equipped with a reliable, stable and capable of bearing a large load. When the rotating mechanism is deployed in place, the target structure can be achieved through the locking mechanism. Maintain a stable pose at the target p...
