Problems solved by technology

However, when the pyrotechnic device is working, it will have a severe impact on the structure and components, and it is easy to cause damage to the electronic equipment and optical components on the aerospace equipment. The cost of the test is high, and special storage and transportation conditions are required, which makes the application cost of the pyrotechnic device in the compression release mechanism in the aerospace field relatively high

Abstract

The invention relates to the technical field of spaceflight, and discloses a pressing and releasing mechanism which comprises a base, a sliding block, a locking assembly, a pulling releasing assembly,a separating piece; the base is arranged on a satellite body or an aircraft body; an unlocking releasing cavity is arranged in the base; the sliding block is in sliding connection with the internal wall of the unlocking releasing cavity; the locking assembly is pressed by the sliding block after sliding tightening, and one end of the locking assembly is limited and pressed into the unlocking releasing cavity, the other end of the locking assembly is used for pressing a pressing piece onto the satellite body or the aircraft body; the pulling releasing assembly is arranged on the base, and canpress or unlock the abut contact of the sliding block and the locking assembly; and the separating piece is connected between the locking assembly and the pressing piece and is used for enabling the locking assembly to be disengaged from the unlocking releasing cavity. The pressing and releasing mechanism is quick in response during working, small in generated impact, free of pollution and capableof being repeatedly used.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a compression release mechanism. Background technique [0002] In the field of aerospace technology, compression and release mechanisms are widely used, such as the deployment and release of antennas and solar panels, and the separation of rockets and satellites. The compression release mechanism can compress and constrain the compression part on the satellite body or the body at certain stages, and can also release the constraint to the compression part after receiving instructions, so that the compression part can be separated from the satellite body or the body. [0003] At present, the compression and release mechanisms commonly used in the aerospace field are mostly pyrotechnic devices, which use gunpowder to burn or explode to release components. However, when the pyrotechnic device is working, it will have a severe impact on the structure and components, and it is easy...
