Lock release device and spacecraft

Abstract

The invention discloses a locking and releasing device and a spacecraft. The disclosed locking and releasing device includes a base, a plurality of split lock rings, a limiting component, a driving component and a connecting piece, and the limiting component is a ring structure and set around the plurality of split lock rings; the limiting assembly is rotatably arranged on the base along its central axis, and has a first state and a second state, and the driving assembly and the The limit assembly is connected, and can drive the limit assembly to rotate to switch from the first state to the second state; wherein, in the first state, the limit assembly and the plurality of The outer peripheral sides of the split lock rings abut against each other, so that the plurality of split lock rings surround and form a locking space, and the connecting piece can be snap-fitted into the locking space; in the second state , the limiting component releases the plurality of split locking rings. The above scheme can achieve the technical effects of reducing the weight of the device, reducing the impact load and reducing pollution.

Description

technical field [0001] The invention relates to the technical field of locking and releasing devices for spacecraft, in particular to a locking and releasing device and a spacecraft. Background technique [0002] With the continuous development of space technology, the application scale of spacecraft (including artificial satellites, deep space probes, etc.) continues to expand. Locking and unlocking are the key technologies for spacecraft in-orbit flight, which are used to realize key actions such as solar wing deployment, antenna deployment, and payload release, and this technology needs to be realized based on a locking and releasing device. [0003] At present, the relevant locking and releasing devices are usually pyrotechnic devices, and its technology has been relatively mature and stable, but there are obvious defects such as heavy device weight, large impact load, and serious explosion pollution. Contents of the invention [0004] The invention discloses a lockin...
