Abstract

The invention discloses a low-impact repeatable locking and separation device for a space effective load. Large-scale capturing and locking of the effective load can be well achieved through rotary swinging and a straight line movement coupling design of a latch hook in a crank slide block assembly; effective resistance to in-plane load borne by the effective load in the launching process can be achieved through cooperation using of a supporting seat oblique plane structure and a compression block oblique plane structure; speed reduction and torque increasing effects can be achieved by arranging a worm and a gear between a motor and the crank slide block assembly, and meanwhile, the locking reliability of the device to the effective load can be ensured through the self-locking property; the device has good expansion performance, can adapt to locking and separation of effective loads with different sizes and volumes, and not only can meet the requirements for spaceflight locking and separation missions, but also can meet repeated locking and separation requirements of various cargoes in the industrial transporting process by changing the physical dimension of the effective load according to needs.

Description

technical field [0001] The invention belongs to the technical field of aerospace equipment, and in particular relates to a low-impact repeatable locking and separating device for space payloads. Background technique [0002] The traditional space payload represented by satellites is locked by a locking device during the launch process, and is unlocked by a pyrotechnic device after reaching the predetermined orbit. Unlock Impact. In order to meet the needs of space missions such as on-orbit modular assembly, construction and upgrade of large spacecraft modules, the payloads such as CubeSats can be reliably locked during the launch phase, and the payloads can be locked repeatedly while on-orbit. The device with separation function has become one of the research hotspots at home and abroad. At the same time, it is required to develop the device with the advantages of low impact, miniaturization, light weight and scalability in the locking separation process, so as to improve a...
