Abstract

The invention discloses a strong connection and weak unlocking device. The device comprises a first connecting piece, a second connecting piece, locking position bodies and a piston, wherein a drivingopening is formed in the first connecting piece, and a plurality of first grooves are formed in the first connecting piece; the second connecting piece is provided with a plurality of second grooves,and the second grooves are matched with the first grooves to form locking position grooves; and the locking position bodies are arranged in the locking position grooves, the piston is movably arranged in a cavity defined by the first connecting piece and the second connecting piece, and is provided with a locking position for connecting the first connecting piece to the second connecting piece, and an unlocking position for unlocking the first connecting piece and the second connecting piece, at least part of the outer surface of the piston forms groove bottoms of the second grooves, when thepiston is located in the locking position, the locking position bodies are limited in the locking position grooves, and when a driving device drives the piston to move to the unlocking position through the driving opening, the locking position bodies leave the locking position grooves, the structure is simple, unlocking is convenient, and the required unlocking force is small.

Description

technical field [0001] The invention relates to the technical field of spacecraft connection and separation structures, in particular to a strong connection weak unlocking device. Background technique [0002] In the field of spacecraft launch technology, connecting and unlocking devices occupy an important position. As the key components of the spacecraft launch stage, the connection and unlocking device directly affects whether the space mission can be successfully completed. Such as the opening and closing of the automaton, the separation of the stages, the deployment of the solar wing of the satellite, and the deployment of the antenna. [0003] Most of the traditional pyrotechnic separation devices are driven by pyrotechnic devices, which have pollution and large impact. The carrying capacity, unlocking capacity and impact response are all proportional to the charge of the pyrotechnic system. A pneumatic connection unlocking device is disclosed in the prior art, which...
