Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an antenna device suitable for installation in a shelter mounted on a moving vehicle, for example.

(Prior art) In general, this type of antenna device is installed on the top of a shelter or the like mounted on a moving vehicle, and when it is moved on a public road, it is regulated by the safety standards of the Road Transport Vehicle Act. The vehicle cannot be moved unless it is adapted to the size of the vehicle being used, the size of the cargo, etc. Therefore, when moving the antenna device, the operator must construct the antenna device each time or disassemble large components such as the flap and horn, remove them from the moving vehicle, and store the parts in the shelter. It was moved to the desired location, and once it arrived, it was reassembled by workers into a usable state.

However, due to the structure of the antenna device, an operator must disassemble the components on a moving vehicle, store them in the vehicle, and reassemble them on the vehicle, which is a very troublesome work. The problem was that the work was dangerous. In addition, according to this, since there are precision parts such as reflectors and horns among the components, repeated disassembly and assembly may cause problems such as the surface precision of the reflector being deteriorated, resulting in a decrease in precision. Was.

(Problems to be Solved by the Invention) This invention was made in order to solve the above-mentioned problems that the disassembly and assembly work was troublesome and dangerous, and caused a decrease in accuracy. It is an object of the present invention to provide an antenna device which is capable of automatically deploying and retracting a reflector.

[Structure of the Invention] (Means and Effects for Solving the Problems) The antenna device of the present invention is mounted on a base that is movably supported in the azimuth direction with respect to an object, and on an elevation angle with respect to the base. a support member that is rotatably supported in a direction, a reflector that is rotatably supported in an elevation angle direction with respect to the support member and controls a deployment position and a storage position, and a reflector that is supported on the support member in a manner corresponding to the reflector. A horn that controls the deployment position and storage position,
an elevation angle adjustment mechanism, one end of which is rotatably connected to the base and the other end rotatably connected to the reflector in the elevation angle direction; and the support at the storage position of the reflector. and a regulating means for regulating the member to the base, the expansion and retraction of the reflector can be controlled to operate the elevation angle adjustment mechanism while the support member is regulated to the base at the reflector storage start position. It is characterized in that the support member is controlled to rotate in conjunction with each other. (Example) Hereinafter, examples of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an antenna device according to an embodiment of the present invention, and 10 in the figure is a shelter mounted on a moving vehicle (not shown). A base 11 is installed in the shelter 10 so as to be rotatably controllable in the azimuth direction (directions of arrows A and B) via an azimuth adjustment mechanism (not shown). As supporting members, a pair of bearings supports the boxes 12 and 12 so as to be rotatable in the height direction (directions of arrows C and D). In this bearing, a beam flap 13 is placed in a box 12.12. A pair of holding parts 13a and 13b are provided on the back side of the reflector 13.
2.12. This holding part 13a, 1
The bearings 3b are supported by a box 12.12 through shafts 13c and 13d, respectively, so as to be rotatable in the directions of arrows C and D, and the sides thereof are detachable fixtures 14.14 for holding the deployed position.
The bearing is fixed in the deployed position with respect to the box 12.12. And the above-mentioned holding part 13a.

One end of the height angle adjustment mechanism 15 is connected to the shaft 15 in the middle part of the height angle adjustment mechanism 13b.
The height angle adjusting mechanism 15 is rotatably connected in the directions of arrows C and D via a, and the other end of this elevation angle adjustment mechanism 15 is rotatable in the directions of arrows C and D with respect to the base 11 via a shaft 15b. connected to.

In addition, the above bearing is placed in the middle part of box 12.12 as shown in Fig. 1 (a).
), a lock pin 16 for position regulation is formed corresponding to a lock hole 17 for position regulation provided at a predetermined position of the base.

This lock bin 16 is provided so as to be movable in the axial direction via a spring member (not shown), and its height angle adjustment mechanism 1
5 is disposed so as to face the lock hole 17 of the base 11 at the stop position.

Furthermore, the horn support 18 is rotatably supported in the box 12.12 via the shaft 11b in the directions of arrows C and D. This horn support 18 has one end corresponding to the shaft 11b that can be fixed in the deployed position using a detachable fixture 19 for holding the deployed position, and a horn 20 corresponding to the reflector 13 at the other end. It is attached.

In the above configuration, during operation, the bearing is fixed to the box 12.12 using the fixing devices 14 and 19, respectively, and the base is mounted by the height angle adjustment mechanism 15, which is driven and controlled by a control section (not shown). 11, the bearing box 12 degrees 12 is controlled to rotate in the directions of arrows C and D, and the height angle directions of the reflector 13 and horn 20 are controlled. At the same time, the base 11 is driven and controlled in the azimuth direction by the azimuth adjustment mechanism (not shown), thereby adjusting and controlling the azimuth directions of the reflector 13 and the horn 20.

Next, when storing, first, the height angle adjustment mechanism 15 is driven and controlled to the stop position as shown in FIG. 2(a).

Then, the bearing box 12.12 is rotated in the direction of the arrow,
The lock pin 16 is inserted into the lock hole 17 of the base 11 and regulated by the base 11. Here, the fixing member 19 of the horn support 18 is removed as shown in FIG. It is fixed using Further, the fixture 14 of the reflector 13 is removed, and the bearing is released from the box 12.12. Thereby, the reflector 13 is adjusted to the height angle adjustment mechanism 1.
5 is driven and controlled, the bearing is rotated in the direction of the arrow 12 with respect to the box 12 through the shaft 130.13d and stored in the side of the shelter 1o (Fig. 2 (C), (d) )reference)
, is fixed by a fixing member not shown here.

In addition, in the above-mentioned stored state, when unfolding again, the above-mentioned angle adjustment mechanism 15 is reversely driven. Then, the reflector 13 performs an operation substantially opposite to the retracting operation described above, and the second
It is expanded to the position shown in Figure (b). Here, the reflector 13 is fixed to the bearing box 12.12 using the fixture 14, and the lock bin 16 of the bearing box 12.12 is removed from the lock hole 17 of the base 11.
Deployment is complete. On the other hand, the horn support 18 is rotated in the direction of the arrow to be expanded, and in the expanded position, the bearing is fixed to the box 12.12 using the fixture 19.

In this way, the antenna device is configured to automatically retract and deploy the reflector 13 in conjunction with the drive control of the height angle adjustment mechanism 15, so disassembly and assembly work is not performed manually as in the past. This work is much easier than what was previously done. Further, according to this, since there is less labor-intensive work for the operator such as removing the reflector 13 and the horn 20 from the base 11, it is possible to store and deploy safely and quickly even in weather conditions such as strong winds and rain. becomes possible.

Note that this invention is not limited to the above embodiments, but also includes
It goes without saying that various modifications can be made without departing from the spirit of the invention.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide an antenna device that has a simple configuration and is capable of automatically deploying and retracting a reflector.
