The end of the second frame portion 22 facing away from the first frame portion 21 is provided with a connecting hole 221. The connecting holes 221 of the two second frame portions 22 are arranged coaxially. The rotating shaft 3 is provided with the first through hole 121 and the second through hole 211. The rotating shaft 3 is rotatably connected to the column 1, and the rotating shaft 3 is fixedly connected to the connecting frame 2.

[0040] Further references Figure 6 As shown, this embodiment also provides a satellite antenna, which includes a base 5 and an antenna dish assembly 6, and also includes the above-mentioned bracket assembly. The column 1 is fixedly supported on the base 5 through a support platform 11, and the antenna dish assembly 6 is connected to the second bracket part 22 through a connecting hole 221, and the antenna dish assembly 6 is partially located in the U-shaped groove 201.

[0041] In this embodiment, the first frame 21 and the two second frame parts 22 jointly form a U-shaped groove 201, and a connection hole 221 is provided at one end of the second frame part 22 facing away from the first frame part 21. The antenna dish assembly 6 can be connected together through the two connection holes 221. The antenna dish assembly 6 can be partially located in the U-shaped groove 201, and the setting of the U-shaped groove 201 can also provide an effective accommodation space for the partial structure of the antenna dish assembly 6 and reasonably layout the space. The column 1 and the connecting frame 2 can realize rotation adjustment through the rotating shaft 3, that is, the bracket assembly can realize horizontal rotation adjustment after assembly to adjust the swing angle of the antenna dish assembly 6. After assembly, the above-mentioned column 1 and the connecting frame 2 can form a structure similar to a "Y" shape, which can reliably and stably support the antenna dish assembly 6 when used for satellite antennas, can better cope with complex and extreme weather environments at sea, adapt to the use of ships at sea, reduce the failure rate and maintenance costs, and ensure the reliability and effectiveness of ship maritime communications.

[0042] The specific structure of the antenna dish assembly 6 is prior art and is not the focus of this application, so it will not be described in detail here.

[0043] It is worth mentioning that a pitch driving component (not shown) may be provided on the second frame portion 22 , and the pitch driving component can be connected to the antenna dish assembly 6 and realize the pitch and swing movement of the antenna dish assembly 6 relative to the connecting frame 2 .

[0044] In this embodiment, the materials of the column 1 and the connecting frame 2 are both set to be materials that can resist seawater corrosion, such as 316 stainless steel or aluminum alloy.

[0045] In this embodiment, the column 1 and the connecting frame 2 are cast. Specifically, in the selection of materials for the column 1 and the connecting frame 2, materials that are easy to cast and process are selected, thereby reducing production costs and improving production efficiency.

[0046] Continue to refer to Figures 1 to 5 As shown, the axis directions of the first through hole 121 and the second through hole 211 are arranged parallel to the extending direction of the second frame portion 22 .

[0047] Specifically, the first frame portion 21 is transitionally connected to the second frame portion 22 on the corresponding side through the rounded frame portion 23. By providing the rounded frame portion 23, the first frame portion 21 and the second frame portion 22 can be smoothly transitionally connected to avoid the appearance of a sharp angle structure, which can avoid stress concentration on the one hand, and improve safety on the other hand, and avoid stabbing people on the scene.

[0048] Specifically, the support platform 11 is provided with a plurality of mounting holes 111. The base 5 of the satellite antenna is provided with a plurality of fixing holes (not shown) correspondingly, and the mounting holes 111 and the fixing holes can be fixedly connected by bolts. Specifically, the fixing holes are set as threaded holes, and the bolts pass through the mounting holes 111 and are threadedly connected with the fixing holes.

[0049] Specifically, the side wall of the column 1 is provided with a first weight-reducing groove 13, and the side wall of the connecting frame 2 is provided with a second weight-reducing groove 24. On the basis of ensuring the strength and reliability of the column 1 and the connecting frame 2, the first weight-reducing groove 13 and the second weight-reducing groove 24 can correspondingly reduce the materials used in the column 1 and the connecting frame 2, thereby reducing the production cost.

[0050] Specifically, two connectors 12 are arranged at intervals at the second end of the column 1, and each connector 12 is provided with a first through hole 121. The two first through holes 121 are arranged coaxially. When the column 1 is connected to the connecting frame 2 via the rotating shaft 3, the rotating shaft 3 is sequentially provided with one of the first through holes 121, the second through hole 211 and another first through hole 121, and the rotating shaft 3 is rotatably connected with the two first through holes 121.

[0051] Specifically, the column 1 is provided with an annular embedding groove connected to the first through hole 121, and a bearing 14 is embedded in the annular embedding groove. The column 1 is rotatably connected to the rotating shaft 3 through the bearing 14. Specifically, each connector 12 is provided with an annular embedding groove, that is, the number of annular embedding grooves is set to two. The number of bearings 14 is also set to two accordingly.

[0052] Specifically, the connector 12 is further provided with a cover plate 15 on the outer side of the annular embedding groove. The cover plate 15 can be covered on the bearing 14 to prevent the bearing 14 from coming out of the annular embedding groove.

[0053] Specifically, the connecting frame 2 is fixedly connected to the rotating shaft 3 through the locking member 25. The first frame portion 21 is provided with a first locking hole 212, the rotating shaft 3 is provided with a second locking hole 31, the locking member 25 penetrates the first locking hole 212 and the second locking hole 31, and is fixedly connected to the second locking hole 31. Specifically, the second locking hole 31 is configured as a threaded hole, and the locking member 25 is correspondingly configured as a bolt. The locking member 25 penetrates the first locking hole 212 and is threadedly connected to the second locking hole 31, so that reliable fixation between the connecting frame 2 and the locking member 25 can be achieved.

[0054] In this embodiment, the support assembly further includes a rotation drive member 4, which includes a drive motor 41 and a transmission assembly. The housing of the drive motor 41 is fixed to the column 1, and the output shaft of the drive motor 41 is connected to the rotating shaft 3 through the transmission assembly. The output shaft of the drive motor 41 can rotate the rotating shaft 3 through the transmission assembly. By providing the rotation drive member 4, automatic control of the rotation of the connecting frame 2 relative to the column 1 can be achieved.

[0055] Specifically, the transmission assembly includes a synchronous belt 42 and a synchronous wheel 43, wherein the synchronous wheel 43 is fixedly sleeved on the rotating shaft 3, and one end of the synchronous belt 42 is wound around the output shaft of the driving motor 41, and the other end is wound around the synchronous wheel 43. In this embodiment, when the driving motor 41 is working, the output shaft of the driving motor 41 rotates, driving the synchronous belt 42 to move, so that the synchronous belt 42 drives the synchronous wheel 43 to rotate, thereby realizing the rotation of the rotating shaft 3 to drive the connecting frame 2 to rotate synchronously.

[0056] Specifically, in this embodiment, the synchronous belt 42 is tautly arranged on the synchronous wheel 43 and the output shaft of the driving motor 41. Specifically, the transmission assembly also includes a belt-pressing wheel 44, which is rotatably connected to the column 1. The belt-pressing wheel 44 presses against the outer side of the synchronous belt 42. By providing the belt-pressing wheel 44, the synchronous belt 42 is reliably kept in a taut state, thereby ensuring the reliability and effectiveness of power transmission.

[0057] It is worth mentioning that due to the rotation control of the connecting frame 2, the connecting frame 2 does not need to realize 360° rotation, but only needs to swing within an angle range. Therefore, correspondingly, the synchronous wheel 43 may not be set as a complete wheel body structure. Such a setting can further reduce the overall size of the structure while ensuring the effective transmission of the rotation action.

[0058] In some other optional embodiments, the transmission assembly can also be configured as a driving gear (not shown) and a driven gear (not shown). Specifically, the driving gear is fixedly sleeved on the output shaft of the driving motor 41, and the driven gear is fixedly sleeved on the rotating shaft 3. The driving gear is meshed with the driven gear. When the output shaft of the driving motor 41 rotates, the rotating shaft 3 can also be driven to rotate by the meshing action of the driving gear and the driven gear.

[0059] In this embodiment, after the bracket assembly is assembled, a static load test or a load test simulating the operation of a ship is performed to verify whether the structural strength of the column 1 and the connecting frame 2 meets the design requirements.

[0060] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
