Problems solved by technology
Its response time is within 50ms, and the synchronization of the three explosive bolts is within 10ms, but it is expensive and the cost of use is extremely high. The ground unlocking separation test and related parameter tests need to be unlocked dozens or even hundreds of times. If explosive bolts are used to unlock them, it will cause a huge economic burden to the test, so this unlocking method should not be used for frequent test tasks.
Moreover, the existing unlocking device has a large volume and a very complicated structure, and cannot meet the requirements of high-speed response and high synchronization unlocking

The invention provides a high-speed response electromagnetic pin pulling unlocking device which comprises a device support. A locking bolt, a locking bolt guide sleeve, a locking pin, a pin pulling spring, a locking pin compression rod and an electromagnet are arranged on the device support, wherein one end of the locking bolt is mounted on a target product, and the other end of the locking bolt is inserted into the locking bolt guide sleeve and is locked by the locking pin sleeved with the pin pulling spring. The locking pin compression rod is arranged on the device support through a fixing support, one end of the locking pin compression rod is connected with the locking pin, a stainless steel sheet is arranged at the other end of the locking pin compression rod, a protection screw is arranged on the stainless steel sheet, and a protection cylinder and a baffle with a buffer spring are further arranged on the device support. Unlocking functions with high-speed response and high synchronism are achieved by the aid of simple mechanism motion, pin pulling unlocking is realized under the action of force of the pin pulling spring by powering on and powering off the electromagnet, corresponding problems caused by unlocking through explosive bolts are solved, and accordingly, unlocking through the explosive bolts is simulated and replaced.
Description
technical field [0001] The present invention relates to the technical field of unlocking devices, in particular to an electromagnetic unlocking device with high-speed response in high and low temperature environments, which is a mechanism device that utilizes the rapid response capability of the electromagnetic device to control the action of the mechanism to realize the unlocking of the target product. , suitable for unlocking parts of spacecraft, weapons and equipment. [0002] Background technique [0003] With the rapid development of science and technology in China, unlocking devices are widely used on various spacecraft. At present, spacecraft use multiple locks to ensure high reliability. In order to ensure the reliability and effectiveness of separation parameters, various The unlocking and separation of the spacecraft mainly uses multiple explosive bolts with high-speed response and high synchronization to realize the unlocking and separation. Its response time is...
