Satellite and launch vehicle connection and separation mechanism

Abstract

The invention provides a satellite and launch vehicle connection and separation mechanism, comprising a guide rail, a rear end cover, a front end frame, a separation spring, a push plate, a cabin door and a connection unlocking device, wherein the rear end cover is connected to the rear end of the guide rail; the separation spring is arranged in the guide rail and can stretch and retract along the direction of the rail; the push plate is arranged at the front end of the separation spring and is driven by the separation spring to move frontward or backward; the front end frame is connected to the front end of the guide rail; the cabin door is hinged to one side edge of the front end frame; when the front end frame is covered, a satellite is tightly pressed on the push plate and the separation spring, so that satellite and launch vehicle connection is realized; when the front end frame is opened, the separation spring and the push plate are released to frontward push out the satellite, so that satellite and launch vehicle separation is realized; the connection unlocking device is used for locking or unlocking the cabin door in a non-pyrotechnic door. The satellite and launch vehicle connection and separation mechanism has the advantages of low impact, simple structure, light weight, high separation precision, convenience in installation, low cost, high reliability and the like.

Description

technical field [0001] The invention relates to the connection and separation fields such as star-arrow separation and inter-stage separation, and in particular to a star-arrow connection and separation mechanism. Background technique [0002] At present, the rapid development of CubeSat (CUBESAT) requires a connection and separation mechanism adapted to the launch of the CubeSat, which is used to realize the connection and separation of the satellite and rocket during the delivery of the CubeSat. The existing connection and separation mechanisms generally use pyrotechnic connection to unlock, which has the following disadvantages: large impact; generally only has one installation surface, and the installation layout is inconvenient; the structure is relatively complicated and the cost is high. There are also some box-type separation mechanisms with unreasonable spring structures or unreasonable push plate structures, which lead to poor separation accuracy, and even have pro...

Problems solved by technology

The existing connection and separation mechanisms generally use pyrotechnic connection to unlock, which has the following disadvantages: large impact; generally only has one installation surface, and the installation layout is inconvenient; the structure is relatively complicated and the cost is high

There are also some box-type separation mechanisms, the spring structure is unreasonable or the push plate structure is unreasonable, the separation accuracy is poor, and there are even problems such as push plate stuck and poor reliability.

The existing cubesat separation mechanism still has the problems of no compression design, insufficient compression force, uncontrollable compression force and damage to the star, which may cause damage to the cubesat during flight
