DETAILED DESCRIPTION
Please refer to FIG. 1 and FIG. 2. FIG. 1 and FIG. 2 are diagrams of an antenna system 10 in different view angles according to an embodiment of the present invention. The antenna system 10 includes a supporting tube 12, an antenna module 14 and an adjusting mechanism 16. The adjusting mechanism 16 is installed on the supporting tube 12 and connected to the antenna module 14, so as to adjust an angle of the antenna module 14 relative to the supporting tube 12 for directionally aligning toward a satellite. In this embodiment, the adjusting mechanism 16 is for adjusting an azimuth and an elevation of the antenna module 14 relative to the supporting tube 12 and the satellite.
Please refer to FIG. 3 to FIG. 5. FIG. 3 to FIG. 5 are exploded diagrams of the adjusting mechanism 16 in different view angles according to the embodiment of the present invention. The adjusting mechanism 16 includes a bracket 18. The bracket 18 includes a base 20, a first supporting portion 22 disposed on a first lateral side of the base 20, and a second supporting portion 24 disposed on a second lateral side of the base 20. The first supporting portion 22 and the second supporting portion 24 are respectively disposed on two opposite lateral sides of the base 20 (such as an upper side and a low side), and a pivot hole 221 is formed on the first supporting portion 22. The adjusting mechanism 16 further includes a clamp 26 disposed by a side of the base 20 and located in a position corresponding to the first supporting portion 22 and the second supporting portion 24, and at least one bridging component 28 connecting to a lateral surface of the clamp 26. The clamp 26 is connected to the first supporting portion 22 of the bracket 18 via the bridging component 28. A pivot hole 281 is formed on the bridging component 28. The adjusting mechanism 16 further includes a pivoting component 30 passing through the pivot hole 221 on the first supporting portion 22 and the pivot hole 281 on the bridging component 28, so that the first supporting portion 22 can pivot relative to the bridging component 28. In addition, the clamp 26 is for clamping the supporting tube 12, so as to install the adjusting mechanism 16 on the supporting tube 12. Volume of the adjusting mechanism 16 is minimized because the clamp 26 is disposed by a side of the bracket 18.
The adjusting mechanism 16 can further include a fine tuning screw module 32. Two ends of the fine tuning screw module 32 are respectively disposed on the bridging component 28 and the first supporting portion 22. The fine tuning screw module 32 can include two locking component sets 34 and a screw rod 36. Each locking component set 34 can include a nut 341 and a screw 343 having a side hole. The screw 343 passes through the bridging component 28 (or the first supporting portion 22) and is locked on the nut 341, and the screw rod 36 passes through the screw 343 of the locking component set 34. The screw rod 36 can be rotated to move one of the locking component sets 34 toward the other of the locking component sets 34 along a thread on the screw rod 36, so as to adjust a distance between the two locking component sets 34 for pivoting the first supporting portion 22 relative to the bridging component 28. In addition, a slide slot 223 can be formed on the first supporting portion 22, the adjusting mechanism 16 can further include a guiding component 38 passing through the slide slot 223 and disposed on the bridging component 28, so as to guide the first supporting portion 22 to pivot relative to the bridging component 28 along a track on the slide slot 223.
For strengthening structural intensity of the adjusting mechanism 16, as shown in FIG.3 to FIG.5, the adjusting mechanism 16 can include two bridging components 28. The two bridging components 28 are respectively connected to the lateral surface of the clamp 26 facing the first supporting portion 22 and the second supporting portion 24. The two bridging components 28 are arranged along a longitudinal direction of the clamp 26, and the longitudinal direction is substantially perpendicular to a radial plane Dradial of the clamp 26. Structures and functions of the two bridging components 28 can be identical. For example, the pivot holes 281 are respectively formed on the two bridging components 28. In addition, the adjusting mechanism 16 can further include two pivoting components 30 having the same structures and functions. The two pivoting components 30 respectively pass through the pivot hole 221 on the first supporting portion 22, a pivot hole 241 on the second supporting portion 24, and the pivot hole 281 on the corresponding bridging component 28, so that the first supporting portion 22 and the second supporting portion 24 can pivot relative to the corresponding bridging components 28. Besides, a slide slot 243 can be formed on the second supporting portion 24, thus the adjusting mechanism 16 can include two guiding components 38 correspondingly. The two guiding components 38 can respectively pass through the slide slot 223 on the first supporting portion 22 and the slide slot 243 on the second supporting portion 24, and can be respectively disposed on the corresponding bridging components 28 pivoting to the first supporting portion 22 and the second supporting portion 24, so as to guide the first supporting portion 22 and the second supporting portion 24 to pivot relative to the two bridging components 28 along the track on the slide slots 223, 243. Therefore, the azimuth of the antenna module 14 relative to the supporting tube 12 can be adjusted accurately.
The adjusting mechanism 16 is connected to the antenna module 14, and pivots the antenna module 14 relative to the clamp 26 along a horizontal plane via the first supporting portion 22 and the second supporting portion 24 of the bracket 18 and the bridging component 28. Furthermore, the bracket 18 can further include a third supporting portion 40 and a fourth supporting portion 42. The third supporting portion 40 and the fourth supporting portion 42 can respectively be disposed on a left side and a right side of the base 20, and the clamp 26 can be disposed by the base 20 and be located between the third supporting portion 40 and the fourth supporting portion 42. The adjusting mechanism 16 can further includes a supporter 44 pivoting to the third supporting portion 40 and the fourth supporting portion 42. As shown in FIG. 1 to FIG. 5, the supporter 44 supports the antenna module 14, so that the antenna module 14 can pivot relative to the bracket 18 upwards and downwards via the supporter 44 and the third supporting portion 40 and the fourth supporting portion 42 of the bracket 18, which means the elevation of the antenna module 14 relative to the supporting tube 12 can be adjusted. The adjusting mechanism 16 can further include a fine tuning screw module 46 disposed between the supporter 44 and the third supporting portion 40 (or the fourth supporting portion 42). Structure and functions of components of the fine tuning screw module 46 are identical with the fine tuning screw module 32, and detailed description is omitted herein for simplicity. The fine tuning screw module 46 is for adjusting an elevation of the supporter 44 relative to the bracket 18.
Comparing to the prior art, the adjusting mechanism of the present invention can adjust the azimuth and the elevation of the antenna module relative to the supporting tube. The bracket of the adjusting mechanism of the present invention includes the base and the four supporting portions. The four supporting portions are respectively disposed on four lateral sides of the base, which means the bracket can be a U-shaped structure, and the U-shaped structure can be connected to the lateral surface of the clamp via the bridging component for minimizing the volume of the adjusting mechanism. It should be mentioned that the structure of the bracket is not limited to the U-shaped structure of the above-mentioned embodiment. For example, the bracket can be a square structure or a polygon structure. The present invention improves connection between the bracket and the clamp, so that the angle of the antenna module relative to the supporting tube (the elevation and the azimuth) can be adjusted as the volume of the adjusting mechanism is minimized. Therefore, the adjusting mechanism of the present invention has advantages of easy assembly and easy operation, and manufacturing cost and transportation cost of the adjusting mechanism are decreased effectively.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention.
