Problems solved by technology

However, due to factors such as gravity, gyration inertia and wind load, this traditional portable satellite antenna has high requirements for the precision of the transmission mechanism's gyration clearance, and the production process requirements are also more stringent.
Due to the problems of the above various factors, the overall weight of this portable satellite communication antenna is relatively heavy, and it is inconvenient to carry
[0003] In order to solve the problem of inconvenient carrying, the patent publication number is CN 204088547 U, and the name is a box-type portable satellite antenna, which uses a box as a supporting structure, specifically as figure 1 As shown: it includes a feed source 101, a feed source connecting rod 102, an antenna reflector 103, a reflector transmission mechanism 104 and a box body 105, wherein the box body 105 is used as a pillar of the reflector transmission mechanism 104 in the use state, and in non-use state, it is also used as a storage box for the reflector transmission mechanism 104
On the whole, it plays a certain role of being convenient to carry, but the box is only used as a box for the storage of the reflector transmission mechanism 104, and other components still need to be stored separately, which is not high for portability; meanwhile, the reflector transmission mechanism 104 is heavy in weight. In addition, in the process of adjusting the horizontal angle, it needs to be completed in combination with high-precision transmission gears. Due to the heavy weight of high-precision transmission gears, at the same time, the box-type portable satellite antenna uses a reflector-adjustment device —The structural form of the supporting device, that is, the "big-small-big" structural mode, makes the overall weight larger

Embodiment 1

[0048]Such as Figure 1-Figure 7 As shown, the box-type guide rail portable satellite communication antenna of the present invention includes an antenna communication assembly, a box support assembly, a guide rail base 201 and a drive assembly. The drive assembly is used to provide power for the support assembly to adjust the horizontal rotation and pitch angle. Meanwhile, the box support assembly is located at the bottom of the antenna communication assembly, and the bottom end is slidably connected to the guide rail base 201 . The drive assembly is fixed on the box support assembly. Specifically, the drive assembly may be located inside the box support assembly, or on the upper surface of the box support assembly, or on the The end face of the box support assembly.

[0049] Wherein, the box supporting assembly includes a packing box 202, a pitch support component 203 and a pitch driving mechanism 204; the packing box 202 is provided with a pull rod 217 and a handle 218 on ...

Embodiment 2

[0059] Such as Figure 9 As shown, it differs from Embodiment 1 only in that it adopts a manual adjustment mode, that is, there are changes in the driving components and a human-computer interaction interface 216 . The driving assembly specifically includes a load-bearing wheel 208, a second limiting wheel 210 and a locking position 215; the load-bearing wheel 208 is located at the end of the second limiting wheel 210, and is used to carry the weight of the communication antenna assembly; the second The limiting wheel 210 is located on one side of the guide rail base 201, and is engaged with the strip groove 206 (a); the first limiting wheel 205 is located on the other side of the guide rail base 201, and is used to limit the driving assembly on the guide rail base. 201 slides in the bar-shaped groove 206 (a), and the locking position 215 is located on one side of the second limiting wheel 210, which is used to lock the second limiting wheel 210 after star alignment, so that t...

Embodiment 3

[0063] Such as Figure 11 As shown, the difference between this embodiment and Embodiment 1 is that: the antenna reflective surface 212 adopts the mode of forward installation, and the mode of reverse installation is adopted in Embodiments 1 and 2. Specifically, it can be combined with Embodiment 1 middle image 3 and Figure 4 Compare.

[0064] For the forward or reverse installation of the antenna reflective surface 212, there are two different usage methods. Specifically, both have the same antenna gain and the same ability to receive signals; the difference is that the antenna reflective surface 212 installed in the forward direction is used in an environment with a wide front view. The antenna reflecting surface 212 can make the antenna receiving surface free of dust and snow accumulation; the antenna reflecting surface 212 installed in the reverse direction is suitable for an open environment above the receiving surface, can save space, and has better wind resistance ...

Abstract

The invention discloses a box-type guide rail portable satellite communication antenna, and the antenna comprises an antenna communication assembly, a box body supporting assembly, a guide rail pedestal, and a drive assembly which is used for providing horizontal rotation and pitching inclination power for the box body supporting assembly. The box body supporting assembly is located at the bottom of the antenna communication assembly, and the bottom of the box body supporting assembly is slidingly connected to the guide rail pedestal. The drive assembly is fixed on the box body supporting assembly. All parts can be put in a box body under the condition of guaranteeing the high-precision mechanical transmission required by the antenna communication assembly for a tracking signal. The antenna achieves an integrated design, and the box body serves as a part of the whole body, thereby enabling the whole antenna to be more convenient.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, and in particular relates to a box-type guide rail portable satellite communication antenna. Background technique [0002] VSAT satellite communication antennas are called miniature stations, small data stations or very small aperture terminals. VSAT systems can support a variety of business types. The terminal antennas are small, compact in design, low in power consumption, low in cost, easy to install, and environmentally friendly Low. However, due to factors such as gravity, gyration inertia, and wind load, this traditional portable satellite antenna has high requirements for the precision of the transmission mechanism's gyration clearance, and the manufacturing process requirements are also more stringent. Due to the above various factors, the overall weight of this portable satellite communication antenna is relatively heavy, and it is inconvenient to carry. [0003] In ord...
