Abstract

The invention discloses a locking and releasing device and a spacecraft, the disclosed locking and releasing device comprises a base, a plurality of sectioning lock rings, a limiting assembly, a driving assembly and a connecting piece, the limiting assembly is an annular structural part and is arranged around the sectioning lock rings; the limiting assembly is rotatably arranged on the base along a central shaft of the limiting assembly and has a first state and a second state, and the driving assembly is connected with the limiting assembly and can drive the limiting assembly to rotate so as to be switched from the first state to the second state; wherein in the first state, the limiting assembly abuts against the peripheral side faces of the multiple sectioning lock rings, so that the multiple sectioning lock rings are enclosed to form a locking space, and the connecting piece can be clamped and matched in the locking space; and in the second state, the limiting assembly releases the multiple sectioning lock rings. According to the device, the technical effects of reducing the weight of the device, reducing the impact load and reducing pollution can be achieved.

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. [0003] At present, the related locking and releasing devices are usually of the pyrotechnic type, the technology of which has been relatively mature and stable, but there are obvious defects such as heavy device weight, large impact load, and serious explosion pollution. SUMMARY OF THE INVENTION [0004] The invention discloses a locking and releasing device and a spacecraft, so as to reduce the weight of the ...
