In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic structural diagram of a satellite communication portable station according to an embodiment of the present application. Referring to fig. 1, the satellite communication portable station includes a reflector antenna 100, a feed support 200, a locker 300, and a feed assembly 400.
The reflector antenna 100 is used for receiving and feeding back signals. The feed support 200 includes a pivoting end 210 and a mounting end 220. The reflector antenna 100 is pivotally connected to the pivotal end 210 of the feed support 200. The reflector antenna 100 can be folded with the feed support frame 200 and unfolded at a predetermined angle with respect to the feed support frame 200. The mounting end 220 of the feed support frame 200 is configured with a reserved space.
The feed assembly 400 includes a feed 410, a power amplifier 420 connected to the feed 410, and a shaft disposed at a connection of the feed 410 and the power amplifier 420. The rotating shaft is connected with the mounting end 220 of the feed support frame 200, and the feed source 410 and the power amplifier 420 are configured to rotate along with the rotating shaft.
Retaining member 300 is coupled to the pivot arrangement for retaining feed assembly 400 in the first and second positions, respectively. Herein, a position where the feed 410 faces the reflector antenna 100 and can perform normal operation with the reflector antenna 100 is defined as a first position. The position where the power amplifier 420 is accommodated in the reserved space of the mounting end 220 is defined as the second position, which is suitable for the case where the feed 410 is located outside the end portion of the mounting end 220, and only the power amplifier 420 is accommodated in the reserved space. Alternatively, when the power amplifier 420 and the feed 410 are both accommodated in the reserved space at the mounting end 220, the position when the power amplifier 420 and the feed 410 are both rotated into the reserved space is defined as the second position.

Retaining member 300 makes feed subassembly 400 fix in first position, and the angle of feed 410 during operation orientation plane of reflection antenna 100 is in same position all the time, because the position and the angle of feed 410 can be located appointed position all the time, so the portable station of satellite communication in this application avoids carrying out the later maintenance in the precision adjustment that can realize feed 410 position and angle. Meanwhile, the feed source support frame 200 in the application is configured with a reserved space capable of accommodating the power amplifier 420 or the power amplifier 420 and the feed source 410, because the volume of the feed source 410 is usually smaller, when the reflector antenna 100 and the feed source support frame 200 are in a folded state, the power amplifier 420 and the feed source 410 can almost be considered to be all accommodated in the reserved space of the feed source support frame 200, so that the volume of the satellite communication portable station is only the volume of the reflector antenna 100 and the feed source support frame 200, thereby realizing the minimum envelope of collection and carrying, and being more convenient to carry.

The preset turning angle between the reflector antenna 100 and the feed support frame 200 can be maintained through at least two forms: first, there is a friction between the reflecting surface antenna 100 and the pivot, and the friction can prevent the reflecting surface antenna 100 from rotating relative to the pivot after the reflecting surface antenna 100 is located at a predetermined position. The reflector antenna 100 is connected with the pivot in a smooth rotation manner, the reflector antenna 100 is fixed through a support rod, referring to fig. 1, the support rod is arranged on the first feed source support arm (or the second feed source support arm), and the support rod 500 enables the reflector antenna 100 and the feed source support frame 200 to keep a preset turning angle. The support rod 500 may be a rod body having a predetermined length, and may also be a hydraulic rod or a pneumatic rod capable of adjusting the length of the rod body.
It should be noted that, in the present application, no specific limitation is imposed on how to maintain the predetermined turning angle between the reflector antenna 100 and the feed support frame 200, and any structure that can realize mutual rotation between the reflector antenna 100 and the feed support frame 200 and maintain the reflector antenna 100 and the feed support frame 200 fixed at the predetermined turning angle falls into the protection scope of the present application.
Referring to fig. 2, the end of the first feed support arm 230 at the mounting end 220 is adjacent to the end of the second feed support arm 240 at the mounting end 220 by a predetermined distance, and a gap between the first feed support arm and the second feed support arm near the mounting end 220 forms a reserved space of the mounting end of the feed support frame 200.

Meanwhile, the structure of the mounting plate 221 can also increase the mounting area of two sides of the mounting end of the feed source support frame 200, and is beneficial to mounting of various structures.

The plate body is made of materials including but not limited to iron plates, stainless steel plates and the like.
In one possible implementation, the rotating shaft 600 for connecting the feed source assembly 400 and the feed source support frame 200 includes a first rotating shaft. The first rotating shaft penetrates through the connection between the feeding source and the power amplifier 420, and one end of the first rotating shaft penetrates through the outer side surface of the first feeding source support arm 230 by a predetermined length. The other end of the first rotating shaft penetrates through the outer side surface of the second feed source support arm 240 by a preset length.

It should be noted that the limiting groove may also be only disposed on the second feed support arm 240, or both the first feed support arm 230 and the second feed support arm 240 are disposed with limiting grooves, and the limiting groove on the first feed support arm 230 and the limiting groove on the second feed support arm 240 are symmetrical with respect to the longitudinal central cross section of the feed support frame 200.
In the implementation process, the design of the mechanical limiting part and the limiting groove is used for judging whether the satellite communication portable station reaches the position of the collection state. When the satellite communication portable station needs to be stored, the feed source and the power amplifier 420 rotate towards the direction of the reflector antenna 100 together, the reflector antenna 100 rotates towards the direction of the feed source and is buckled downwards, when the mechanical limiting part of the rotating shaft 600 reaches the limiting groove of the feed source support arm, the rotating shaft 600 can not rotate any more, at the moment, the threaded locking part 300 is screwed in and locked, and the storage of the satellite communication portable station is realized, and the reference of figure 4 is shown.
