Description
Technical field
The present invention relates to satellite communication fields, and in particular to a kind of magnetic-type satellite antenna unfolding mechanism.
Background technique
Satellite antenna is the important component of satellite, is applied to outside satellite capsule, predominantly rack supporting structure, in space flight
Device launching phase bracket is in folded state, and after spacecraft enters planned orbit, bracket expansion makes satellite antenna stretching, extension carry out signal
Transmitting-receiving work.In order to improve the quality of receiving and transmitting signal, antenna reflective face needs to have specific shape, and wants with higher
Surface accuracy.
Existing satellite antenna unfolding mechanism there are the problem of specifically include that
(1) structure is complicated and surface accuracy is difficult to ensure for antenna holder, and since satellite antenna size is larger, amount of parts is many
It is more, it needs to add specific retaining mechanism and keeps relative position between components, lead to that structure is complicated；Excessive components drop
Low stiffness of support causes surface accuracy to be difficult to ensure in addition the precision of retaining mechanism is difficult to control.
(2) be difficult to realize complicated reflector shape, existing satellite antenna mainly by the way of the covering on bracket,
Bracket is difficult to carry out the everywhere of reflecting surface operative constraint in shape, it is difficult to realize complicated reflector shape.
Summary of the invention
To solve the above problems, the invention discloses a kind of magnetic-type satellite antenna unfolding mechanism, structure is simple, positioning accurate
Degree is high, is able to achieve complex reflex face shape.
In order to achieve the above objectives, technical scheme is as follows:
A kind of magnetic-type satellite antenna unfolding mechanism, including magnetic sheet and flexible antennas reflecting surface, the magnetic sheet are several magnetic
Property block composition arcuate structure, the flexible antennas reflecting surface is pasted onto the concave side of arcuate structure, and magnetic sheet uses winding side
Formula is stored and is unfolded.
As an improvement of the present invention, the magnetic block is inverted trapezoidal structure.
As an improvement of the present invention, magnetic pole is different between two neighboring magnetic block.
The beneficial effects of the present invention are:
(1) magnetic sheet is stored and is unfolded using winding method, during antenna expansion, utilizes magnetic pole between magnetic sheet
Between mutual attractive force realize fitting, be not necessarily to further retaining mechanism, structure is simple, and rigidity is big, and antenna surface accuracy is high.
(2) flexible antennas reflecting surface is pasted onto magnetic board group concave side, only need to carry out specific shape to magnetic sheet concave side
Shape processing, can be realized complicated antenna reflective face shape.
Detailed description of the invention
Fig. 1 is the structural schematic diagram after antenna expansion；
Fig. 2 is the structural schematic diagram after antenna storage.
Reference signs list:
1. magnetic sheet；2. flexible antennas reflecting surface, 3. magnetic blocks.
Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.It should be noted that word " preceding " used in the following description,
" rear ", "left", "right", "up" and "down" refer to that the direction in attached drawing, word "inner" and "outside" refer respectively to direction or remote
Direction from geometric center of specific component.
As shown, a kind of magnetic-type satellite antenna unfolding mechanism of the present invention, including magnetic sheet 1 and flexible antennas
Reflecting surface 2, the magnetic sheet 1 is stored (Fig. 2) using winding method and (Fig. 1) is unfolded, after expansion, each magnetic block 3 it
Between by magnetic absorption together, be not necessarily to further retaining mechanism, structure is simple, and positioning accuracy is high, is conducive to improve satellite antenna
Surface accuracy；The flexible antennas reflecting surface 2 is pasted onto magnetic board group concave side, and such antenna reflective face shape depends on
Magnetic sheet concave side shape only need to carry out specific shape processing to magnetic sheet, complicated reflector shape can be realized.
The technical means disclosed in the embodiments of the present invention is not limited only to technological means disclosed in above embodiment, further includes
Technical solution consisting of any combination of the above technical features.
