Abstract: An electromagnetic lock release mechanism includes: a frame, an ejection unit, a satellite unit, a lock release unit, and a lock release drive unit; the ejection unit includes an ejection spring, an ejection jack, and a spring sleeve; the lock release unit includes a locking pin, a locking slider, an unlocking spring, and a base; the lock release drive unit includes an electromagnet limit nut, an electromagnet moving core, and an electromagnet. Advantages of the present invention are as follows. The present invention is a point positioning lock release mechanism that can be used to separate micro-satellites and rockets and repeatedly tested, which provides reliable locking and separating of satellites and rockets in a complex mechanical environment, and can be repeatedly tested on the ground. The separation is entirely a mechanism action without pollution.
