Description
Technical Field

Background
The solar wing is a device for collecting solar energy and supplying energy to the space satellite, and is an energy source of the space satellite. The space satellite is limited by a carrying space in a launching state, the solar wings are required to be folded and collected on the side walls of the satellite in a launching stage, and the solar wings of the satellite are unfolded into a plane shape after the satellite is separated from the rocket.
The unfolding mechanism of the satellite solar wing plays an important role in the launching and running processes of the satellite, the unfolding of the solar wing is a very important link for the satellite to enter a real working state, if the solar wing cannot be unfolded, the satellite loses working capacity due to gradual reduction of residual energy of a battery, and the service life of the satellite in orbit flight is further seriously influenced, so that the unfolding mechanism of the satellite solar wing is a key component for ensuring the normal running of the satellite.
The common solar wing spreading mechanisms at present are divided into two types: the active and passive solar wing mechanism is generally used as a repeatable folding and unlocking type solar wing mechanism, is applied to a large satellite more frequently, is driven by a motor generally, but consumes power resources and has a more complex structure.
For the microsatellite, the solar wing is usually unfolded by adopting passive driving, the solar wing is usually driven by a spring, the spring is pre-stressed to store potential energy of the spring during folding, and after the mechanism is unlocked, the spring releases the elastic potential energy to realize unfolding of the mechanism. The spring driving mode has the advantages of relative independence of the system and higher reliability. However, the driving force driven by the spring is not easy to control, and strong collision between adjacent solar wing panels is easily caused at the moment when the stretching is finished, so that the stretching process is uncontrollable, the stability of the locking and releasing process is poor, and the synchronous unfolding is uncontrollable. Meanwhile, the vacuum cold welding effect exists in a vacuum environment, so that the moving part also needs to be provided with a means for preventing the vacuum cold welding.
