Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0028] In order to reduce the motion envelope of the antenna pointing mechanism above the star deck, reduce the difficulty of star layout, and increase the number and types of single satellites, the invention provides a foldable multi-dimensional unfolding mechanism for space loads. In the launch phase, the folding multi-dimensional deployment mechanism is in a locked state, and the secondary reflector antenna and the main reflector antenna are installed inside the astral cabin. After entering the orbit and unlocking, under the action of the coil spring, the secondary connecting rod rotates 180°, so that both the secondary refl...

Abstract

The invention provides a folding type multi-dimensional unfolding mechanism for a spatial load. The folding type multi-dimensional unfolding mechanism mainly solves the problems that an existing reflector antenna needs to occupy a large envelope space, the carried load is small, and star layout is difficult. The mechanism comprises a folding and unfolding module, a main connecting rod, an auxiliary connecting rod, an auxiliary reflection mounting module, a main reflection mounting module, a main locking module and an auxiliary locking module, the folding and unfolding module is arranged at the edge position of the star cabin plate and is used for realizing 180-degree overturning of the auxiliary connecting rod; the auxiliary reflection installation module comprises an auxiliary reflection support and an auxiliary reflection motor and is used for achieving rotation motion of the main connecting rod. The main reflection mounting module comprises a main reflection bracket and a main reflection motor and is used for realizing self-rotation of the main reflector antenna; the main locking module comprises a main elastic releasing device, a main locking column and a main locking device pressing plate and is used for achieving position locking of the main connecting rod. The auxiliary locking module comprises an auxiliary elastic releasing device, an auxiliary locking column and an auxiliary locking device pressing plate and is used for achieving position locking of the auxiliary connecting rod.

Description

technical field [0001] The invention relates to a space load unfolding device, in particular to a foldable multi-dimensional unfolding mechanism for space loads. Background technique [0002] In recent years, with the development of satellite communication technology, in order to solve the problem of Internet access in remote areas, aviation, navigation and other fields, satellite Internet technology combining satellite communication and Internet has gradually become one of the main trends in the development of satellite communication technology. With the continuous improvement of the satellite Internet system's requirements for capacity, performance, and on-orbit operating life, how to more efficiently meet different application requirements in different regions and different time domains during satellite in-orbit operation, how to improve transponder utilization efficiency, Improving income returns has become the focus of satellite Internet systems. [0003] The satellite...
