ように構造上の幾何学的考慮が必要となる。 In general, vehicle-mounted antennas are limited by the size of the vehicle (for example, Japanese safety standards limit the width to 2.5m and the height to 3.8m), so it is difficult to apply an antenna with a relatively large diameter to the vehicle. Basic dimensional limitations need to be considered. Furthermore, in order to install an antenna that has a relatively large aperture diameter compared to the vehicle width, it must be appropriately disassembled during transportation and reassembled at the destination, but it is possible to reduce the number of disassembly and assembly steps. required. Furthermore, in order for the antenna to be oriented near horizontally after the antenna is assembled, it is necessary to consider the geometry of the structure so that the outer diameter of the antenna reflector does not touch the ground at least.
本考案の目的は、以上の考察にもとずき、車載

る。 Based on the above considerations, an object of the present invention is to provide an on-vehicle antenna suitable for an on-vehicle structure.

ルター１８が設置されている。 FIG. 1 is a side sectional view of an embodiment of the present invention, and FIG. 2 is a left side view of FIG. 1. In the figure, 1 is a standard trailer truck, and 2 is an outrigger. An azimuth rotation bearing 3 is provided on the chassis 1, and an azimuth rotation stand 4 is provided thereon. An azimuth drive jack 5 is provided on the side surface of the azimuth rotation table 4, and an elevation rotation shaft 6 is provided on the azimuth rotation table 4, and a clevis 8 at one end of the depression drive jack 7 is connected to the azimuth rotation table 4.
It is placed above. An arm 9 is mounted on the elevation rotation shaft 6, and a center hub 11 is provided on the back of the antenna so that the antenna shaft 10 is appropriately spaced from the elevation rotation shaft 6. On the other hand, the elevation drive jack 7
The arm 9 is provided with a moving nut 12 connected to a bearing 13 at one end of the arm 9 via a trunnion. Also,
A frame 14 is provided on the outer periphery of the center hub 11 in a radial direction.
is installed. In this figure, only two sets of skeletons 14 are shown to avoid complication. Also,
Antenna reflector 1 appropriately divided on frame 14
Assemble 5. The center hub 11 has a power feeding system column 16 on the center thereof, and a sub-reflector 17 is integrally attached to the tip thereof. In this figure, a shelter 18 is installed on one side of the vehicle chassis 1 to house communication equipment other than an antenna.

代りに歯車列機構による駆動もできる。 FIG. 3 shows the packaging shown in FIG. 1 during transportation, and the structure is such that it can be transported to the center hub 11 without being dismantled. What will be dismantled are 14 skeletons and 1 reflector.
5 and a power supply system support 16, which are loaded into a space on the undercarriage or onto another vehicle during transportation. Note that FIG. 4 is a side view of the antenna in operation with the antenna assembled and directed toward the satellite. Further, instead of the azimuth drive jack 5, a gear train mechanism can be used.

る。 With such a structure, the number of components that must be disassembled for transportation can be reduced, and the width and height of the vehicle during transportation can be kept within maintenance standards.
Furthermore, since the elevation axis 6 and the antenna axis 10 are appropriately spaced apart, the antenna can be directed from celestial to nearly horizontal. Furthermore, there is no need to disassemble the rotating parts or drive mechanism parts, so handling is easy, and the disassembled components can be divided appropriately.
It can also be assembled manually without using a crane or the like. With this structure, even antennas with diameters exceeding 10M can be applied to vehicles.
