Embodiment Construction
[0035] A low-profile mobile satellite communication antenna servo mechanism, characterized in that it includes: double trimming ring focus antenna 1, polarization tracking gear 2, pitch tracking gear 3, first connecting waveguide 4, azimuth tracking gear 5, base plate 6, installation platform 7. Support and signal transmission integrated shaft system 8, azimuth rotary joint 9, polarized drive gear assembly 10, azimuth drive gear assembly 11, pitch support mechanism 12, pitch drive gear assembly 13, polarized rotary joint 14, second connection waveguide 15, pitching and rotating joint 16, third connecting waveguide 17 and polarization and antenna supporting mechanism 18;
[0036] The double-modified ring-focus antenna 1 is a parabolic edge-cutting antenna, and its main reflection surface has been trimmed. The cutting direction is parallel to the pitch rotation axis, and the size is 0.6mx0.4m. The polarization axis of the double-corrected ring-focus antenna 1 passes through the p...

The invention discloses a servo mechanism for a low-profile mobile satellite communication antenna. The servo mechanism for the low-profile mobile satellite communication antenna comprises a double-correction ring-focus antenna, a slip ring, tracking gears for three axes, a pitching supporting mechanism, a polarizing supporting mechanism, an installation platform, a base plate and the like, wherein the tracking gears for the three axes comprise the azimuth tracking gear, the pitching tracking gear and the polarizing tracking gear, the inner circle and the outer circle of the slip ring are connected with the installation platform and the base plate respectively, the azimuth tracking gear is installed on the base plate and the installation platform, the pitching tracking gear is installed on the pitching supporting mechanism and the polarizing supporting mechanism, and the polarizing tracking gear is installed on the double-correction ring-focus antenna and the polarizing supporting mechanism. The servo mechanism for the low-profile mobile satellite communication antenna is characterized in that the slip ring has the signal breakover function and can serve as an azimuth rotary shaft, the eccentricity design that the pitching supporting mechanism and the polarizing supporting mechanism are in orthogonal connection with the slip ring and are not in intersection with the slip ring, and thus the overall height of the mechanism is greatly reduced. The servo mechanism for the low-profile mobile satellite communication antenna has the advantages that the overall height is small, the size is small, the weight is low, the structure is simple, and assembly and disassembly are convenient. The servo mechanism for the low-profile mobile satellite communication antenna can be applied to the roofs of small cross-country vehicles or other mobile carriers with installation spaces strictly limited.
Description
technical field [0001] The invention relates to a mobile satellite communication antenna servo mechanism, which is suitable for the "communication in motion" mobile satellite communication antenna servo mechanism, and realizes the miniaturization and light weight of the mobile satellite communication antenna. Background technique [0002] At present, "Mobile Communications" at home and abroad are mainly divided into two categories according to their installation modes: the first type is to place the mobile satellite communication antenna inside the mobile carrier, and perform wave-transparent processing on the corresponding position of the carrier; the second type It is to install the mobile satellite communication antenna as a whole in an appropriate position outside the mobile carrier. The first type requires relatively large-scale modification of the carrier to achieve the wave-transparent performance of the carrier, and the volume of the installed mobile satellite commun...
