The invention discloses a non-pyrotechnic low-impact electromagnetic locking and releasing device which comprises a target seat end assembly and a locking pin. the target seat end assembly comprises atarget seat cylinder, a circlip for a hole, a direct-current traction electromagnet, a retainer, a steel ball and a reset spring; the target seat cylinder comprises the structures of a large-diameterinner cavity and a small-diameter inner cavity; the steel ball is installed in a spherical groove of the retainer, the retainer and the steel ball are installed in the small-diameter inner cavity ofthe target seat cylinder together, one end of the reset spring makes contact with the inner end face of the retainer, the other end of the reset spring makes contact with the end face of the direct-current traction electromagnet, and the direct-current traction electromagnet is installed in the large-diameter inner cavity of the target seat cylinder. The device adopts a non-pyrotechnic electromagnetic driving principle, has the characteristics of low unlocking impact, safety, energy conservation, simple structure, reliable connection and reusability, and can greatly reduce the unlocking impactload, prolong the service life of the locking and releasing device and reduce the risk of failure of high-precision detection equipment by adopting an electromagnetic driving mode.
Description
technical field [0001] The invention belongs to the field of aerospace, in particular to a non-pyrotechnic low-impact electromagnetic locking release device. Background technique [0002] Connecting multiple sets of satellites, probes and space vehicles (spacecraft, space stations, spaceships, etc.) in the form of ropes will be more conducive to detection equipment entering deeper space and realizing immediate and effective detection in a wider range , will be able to greatly increase the amount of information collected, and will also be more conducive to the launch and recovery of satellites and probes, reduce the burden on the precise and complex attitude control system, avoid collisions with spacecraft, reduce space debris, and effectively reduce the economic cost of recycling . With the research progress of "multiple satellites with one arrow", "space docking system", and tethered satellite system (TSS) related technologies, the low unlocking impact, high connection and...
