Problems solved by technology
[0003] The disadvantage of the existing technology is that the satellite antenna installed on mobile carriers such as vehicles and ships has a certain inclination angle in some use environments. At the same time, because the earth as a whole is approximately circular, these reasons As a result, the tracking system that can theoretically cover all space on the horizontal plane is difficult to achieve the expected effect, and there is a certain range of tracking dead angles, which affects the use efficiency of satellite antennas

The invention discloses a satellite antenna device mounted on a mobile carrier. The satellite antenna device comprises a base for fixedly connecting the mobile carrier, wherein the satellite antenna device further comprises an antenna base, the antenna base is connected to the base through an angle adjustment mechanism, the angle adjustment mechanism comprises a supporting member, an adjusting rod, an adjusting rod and an angle driving component, one end of the supporting member is fixedly connected to the base, and the other end of the supporting member is rotationally connected to the antenna base; the adjusting rod is in sliding fit with a slide rail through a sliding structure to support the antenna base; an annular rotating mechanism is arranged on the end face of a first gear, and the first gear is rotationally connected to the base through the annular rotating mechanism, an internal thread is arranged on a center hole of the first gear, the angle driving component comprises an angle driving motor and a second gear driven by the angle driving motor, and the second gear is engaged with the first gear. The satellite antenna device mounted on the mobile carrier provided by the invention reduces the blind spot of satellite tracking and improves the tracking capability of the antenna mechanism to the target satellite.
Description
technical field [0001] The invention relates to antenna technology, in particular to a satellite antenna device installed on a mobile carrier. Background technique [0002] The satellite antenna device needs to rotate continuously to track the target satellite. In order to track the satellite in all directions, many rotating pairs need to be set on the satellite antenna device. For example, the authorized announcement number is 103474771B, the authorized announcement date is July 1, 2015, and the invention patent named "Marine Satellite Antenna" includes a base, an antenna shell detachably connected to the base, and a central axis fixed on the base. A base plate that can rotate around the central axis is pierced on the central shaft, a central gear located on the lower side of the base plate is fixed on the central shaft, a first drive motor is fixed on the base plate, and the first drive motor The first planetary gear is fixed on the output shaft, and the first planetary g...
