2. Description of the Prior Art
For receiving signals generated by a satellite effectively, an antenna module includes an adjusting mechanism for adjusting rotary angle of the antenna module according to a position of the satellite relative to the ground. A conventional adjusting mechanism for adjusting an elevation and an azimuth of the antenna module relative to the satellite includes a sheath and a rotating structure. The sheath sheathes on a supporting tube, and the rotating structure is disposed on an end of the sheath (for example, the rotating structure is disposed on top of the sheath), so that the conventional adjusting mechanism can adjust the elevation and the azimuth of the antenna module relative to the supporting tube and the satellite. However, volume of the conventional adjusting mechanism is huge. For example, a height of the conventional adjusting mechanism is the total amount of heights of the sheath and the rotating structure. The conventional adjusting mechanism has drawbacks of expensive manufacturing cost, expensive transportation cost and complicated assembly. Thus, design of an adjusting mechanism with simple structure that has low transportation cost and low manufacturing cost is an important issue of the antenna industry.
The present invention provides a small-size adjusting mechanism that has preferable structural strength and a related antenna system for solving above drawbacks.
According to the claimed invention, an adjusting mechanism includes a supporter for supporting an antenna module. The supporter includes a base, and a supporting component pivotably disposed on the base in a manner of surrounding a first axial direction, so as to adjust an elevation angle of the antenna module. An open hole is formed on a bottom of the base, and the base includes a fixing portion. The adjusting mechanism further includes a foundation pivotably disposed on the base in a manner of surrounding a third axial direction different from the first axial direction, so as to adjust an azimuth angle of the antenna module. A conjunction portion is disposed on a surface of the foundation, and the fixing portion is connected to the conjunction portion for preventing the base from rotating relative to the foundation. The adjusting mechanism further includes a clamper fixed on the foundation. The clamper pierces through the open hole on the base and is partly accommodated between the base and the supporting component. The clamper includes a circular body for clamping a tube, and two connecting parts disposed on lateral surfaces of the circular body. The circular body is fixed on the tube via the connecting parts, and a direction of each connecting part is substantially parallel to a second axial direction perpendicular to the first axial direction.
According to the claimed invention, the fixing portion is a hook, and the conjunction portion is a guiding slot. The hook is slidably buckled inside the guiding slot, so as to constrain a movement of the base relative to the foundation along the third axial direction perpendicular to the first axial direction and the second axial direction.
According to the claimed invention, the fixing portion is an element whereon a lock hole is formed, and the conjunction portion is a guiding slot. The adjusting mechanism further includes a fixing component. The fixing component pierces through the guiding slot and the lock hole on the element, so as to constrain a movement of the base relative to the foundation along the third axial direction perpendicular to the first axial direction and the second axial direction.
According to the claimed invention, an interval height between a bottom of the connecting part and a surface of the foundation is substantially greater than a thickness of the base.
According to the claimed invention, the open hole includes a first area and a second area. A dimension of the first area corresponds to a dimension of the circular body, and a dimension of the second area corresponds to dimensions of the connecting parts.
According to the claimed invention, the base includes a bottom portion, a first lateral portion and a second lateral portion. The first lateral portion and the second lateral portion are respectively disposed on two edges of the bottom portion and movably connected to the supporting component, and a part of the clamper is accommodated between the first lateral portion and the second lateral portion.
According to the claimed invention, superficial measure of the first lateral portion is substantially smaller than superficial measure of the second lateral portion, so as to expose the connecting part of the clamper.
According to the claimed invention, the adjusting mechanism includes a plurality of rib structures. The rib structures are respectively disposed on surfaces of the base, the supporting component and the foundation.
According to the claimed invention, a contacting portion is disposed on a top of the clamper for constraining a movement of the clamper relative to the tube.
According to the claimed invention, an antenna system includes an antenna module, a tube, and an adjusting mechanism disposed between the antenna module and the tube for adjusting angles of the antenna module relative to the tube. The adjusting mechanism includes a supporter for supporting an antenna module. The supporter includes a base, and a supporting component pivotably disposed on the base in a manner of surrounding a first axial direction, so as to adjust an elevation angle of the antenna module. An open hole is formed on a bottom of the base, and the base includes a fixing portion. The adjusting mechanism further includes a foundation pivotably disposed on the base in a manner of surrounding a third axial direction different from the first axial direction, so as to adjust an azimuth angle of the antenna module. A conjunction portion is disposed on a surface of the foundation, and the fixing portion is connected to the conjunction portion for preventing the base from rotating relative to the foundation. The adjusting mechanism further includes a clamper fixed on the foundation. The clamper pierces through the open hole on the base and is partly accommodated between the base and the supporting component. The clamper includes a circular body for clamping a tube, and two connecting parts disposed on lateral surfaces of the circular body. The circular body is fixed on the tube via the connecting parts, and a direction of each connecting part is substantially parallel to a second axial direction perpendicular to the first axial direction.
The present invention disposes the clamper inside the base for reducing the structural height of the adjusting mechanism, so that the dimensions of the adjusting mechanism and the antenna system are decreased, and the manufacturing cost and the transportation cost can be decreased accordingly. The open hole can be formed on the bottom portion of the base, and the shape and the dimension of the open hole can correspond to the shape and the dimension of the clamper for easy assembly of the clamper and the base. In addition, the interval height between the connecting part and the foundation can prevent the bottom portion from being interfered with the connecting parts when the clamper is welded on the foundation, so the base of the present invention can rotate relative to the foundation unrestrainedly. The direction of the connecting parts of the present invention can be substantially parallel to the second axial direction, and the user can fix the locking components on the connecting parts (or remove the locking components from the connecting parts) through the gap between each connecting part and the adjacent lateral portion. Furthermore, the part of the lateral portion of the base can be segmented, so the user can utilize the screw driver to lock and to remove the locking components from the connecting parts due to difference of the superficial measures between the first lateral portion and the second lateral portion.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

The adjusting mechanism 16 further includes a foundation 24 pivotably disposed on the base 20 via assembly of sliding units 48 and sliding holes 50 and assembly of a fastener 54 and an opening 56, and a clamper 26 fixed on the foundation 24 and installed on the tube 14. The base 20 is rotatably disposed on the foundation 24 by the fastener 54 and the opening 56, and the base 20 can slide relative to the foundation 24 according to paths of the sliding units 48 within the sliding holes 50. The adjusting mechanism 16 can utilize the other screw set 40′ disposed between the base 20 and the foundation 24 to rotate the base 20 relative to the foundation 24 along an XY plane, so as to adjust the azimuth angle of the antenna module 12. Ends of the screw set 40′ are rotatably disposed on the foundation 24 and the base 20, respectively. A plurality of contacting portions 261 can be disposed on a top of the clamper 26. The contacting portions 261 can contact against the tube 14 when the clamper 26 is completely installed on the tube 14, so as to constrain a movement of the clamper 26 relative to the tube 14. Meanwhile, the clamper 26 can be locked on the tube 14 and cannot move relative to the tube 14. Because the clamper 26 can be fixed on the foundation 24 by weld, the foundation 24 does not move relative to the clamper 26 and the tube 14. The base 20 of the supporter 18 can rotate relative to the foundation 24 for adjusting the azimuth angle of the antenna module 12 relative to the tube 14. In addition, a conjunction portion 241 is disposed on a surface of the foundation 24. The conjunction portion 241 can be connected to the fixing portion 205, so as to prevent the base 20 from rotating relative to the foundation 24.

It should be mentioned that the maximum elevation angle of the supporting component 22 of the present invention can be set as 65 degrees. A length of the part of the circular body 28 located above the upper surface of the foundation 24 can be designed that is not interfered with maximum rotation of the supporting component 22 of the present invention, which means an inner surface of the supporting component 22 does not contact the top of the circular body 28 when the supporting component 22 rotates relative to the base 20 in a range from 20 degree to 65 degrees, so that the supporting component 22 can rotate arbitrarily within the predetermined range of the elevation angle (from 20 degree to 65 degrees). A radial dimension of the circular body 28 can be designed according to dimensions of the tube 14, a length of the part of the circular body 28 located above the upper surface of the foundation 24 corresponds to dimensions of the base 20 and the supporting component 22 of the supporter 18, and detail description is omitted herein for simplicity. Besides, a direction of each connecting part 30 can be substantially parallel to a second axial direction D2 (Y axis) perpendicular to the first axial direction D1 (X axis), and a user can fix the screw on the connecting parts 30 conveniently through a gap between the connecting parts 30 inside the base 20 and the adjacent first lateral portion 202 and the adjacent second lateral portion 203.

For improving operation convenience of the present invention, directions of the connecting parts 30 of the clamper 26 can be substantially parallel to the second axial direction D2 (Y axis), so the gap between each connecting part 30 and the adjacent lateral portion (the first lateral portion 202 and the second lateral portion 203) can have spacious size. The user can utilize the locking components 52 to fix on the connecting parts 30 (or to remove the locking components from the connecting parts 30) through the gap. As shown in
For example, the bottom portion 201 can be connected to the foundation 24 via a mounting portion and two sliding portions. The base 20 can utilize the mounting portion to be a pivot to rotate relative to the foundation 24 for adjusting the azimuth angle of the antenna module 12. Generally, the foundation 24 and the bottom portion 201 can be designed as rectangular structures, the mounting portion and the sliding portions are respectively disposed on three corners of each rectangular structure, and the assembly of the fixing portion 205 and the conjunction portion 241 can be respectively disposed on the fourth corner, which is different from the corners whereon the mounting portion and the sliding portions are disposed, of the rectangular structure. As the fixing portion 205 is not connected to the conjunction portion 241, and a weight of the antenna module 12 exceeds a load of the mounting portion and the sliding portions, the bottom portion 201 may be overturned relative to the foundation 24 at the fourth corner. Therefore, the four corners of the bottom portion 201 and the foundation 24 can be firmly fixed by the assembly of the mounting portion and the sliding portions and by the assembly of the fixing portion 205 and the conjunction portion 241, so as to constrain a movement of the base 20 relative to the foundation 24 along a third axial direction D3 (Z axis) perpendicular to the first axial direction D1 (X axis) and the second axial direction D2 (Y axis) for increasing operation stability of the adjusting mechanism 16.

In addition, superficial measure of the first lateral portion 202 of the adjusting mechanism 16″ can be substantially smaller than superficial measure of the second lateral portion 203, and the base 20 has kept the sufficient structural strength, so as to expose a part of the connecting parts 30 of the clamper 26. Because the connecting parts 30 are accommodated between the first lateral portion 202 and the second lateral portion 203 of the base 20, a part of the first lateral portion 202 can be segmented for easy operation of the locking components and the connecting parts 30. As shown in
Comparing to the prior art, the present invention disposes the clamper inside the base for reducing the structural height of the adjusting mechanism, so that the dimensions of the adjusting mechanism and the antenna system are decreased, and the manufacturing cost and the transportation cost can be decreased accordingly. The open hole can be formed on the bottom portion of the base, and the shape and the dimension of the open hole can correspond to the shape and the dimension of the clamper for easy assembly of the clamper and the base. In addition, the interval height between the connecting part and the foundation can prevent the bottom portion from being interfered with the connecting parts when the clamper is welded on the foundation, so the base of the present invention can rotate relative to the foundation unrestrainedly. The direction of the connecting parts of the present invention can be substantially parallel to the second axial direction, and the user can fix the locking components on the connecting parts (or remove the locking components from the connecting parts) through the gap between each connecting part and the adjacent lateral portion. Furthermore, the part of the lateral portion of the base can be segmented, so the user can utilize the screw driver to lock and to remove the locking components from the connecting parts due to difference of the superficial measures between the first lateral portion and the second lateral portion.
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. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
