Description

Antenna system and screw mechanism for adjusting the angle of the antenna module

technical field

The invention relates to a screw mechanism and an antenna system, in particular to a screw mechanism and an antenna system for adjusting the angle of an antenna module.

Background technique

The traditional screw mechanism includes a screw rod, a receiving part and a side hole screw, and the receiving part and the side hole screw are respectively arranged at two ends of the screw rod. A thread is formed on the surface of the screw rod and an annular groove is provided, and the accommodating part includes a wedge-shaped protrusion whose width is similar to that of the annular groove. When the screw rod is engaged with the receiving part and the wedge-shaped protrusion is engaged in the annular groove, the user can drive the side hole screw along the thread of the screw rod to produce a displacement change relative to the receiving part by rotating the screw rod. However, with the design trend of miniaturization of the mechanical structure, the volume of the screw mechanism becomes smaller, and the size of the traditional screw becomes shorter and thinner accordingly. Therefore, the grooves formed on the traditional screw greatly weaken the structural strength of the screw. For example, the traditional screw is easily distorted, deformed, or even broken due to the extrusion of the receiving part or the side hole screw. Therefore, how to design a screw mechanism that can take both miniaturization design and structural strength into account is a subject that the machinery industry needs to strive for.

Detailed ways

Please refer to FIG. 1 , which is a schematic diagram of an antenna system 10 according to an embodiment of the present invention. The antenna system 10 includes a support frame 12 , an antenna module 14 and a screw mechanism 16 . The screw mechanism 16 is disposed between the support frame 12 and the antenna module 14 for adjusting the rotation angle of the antenna module 14 relative to the support frame 12 .

Please refer to FIG. 2 and FIG. 3 , FIG. 2 is an exploded view of the screw mechanism 16 according to the embodiment of the present invention, and FIG. 3 is an assembly view of the screw mechanism 16 according to the embodiment of the present invention. The screw mechanism 16 includes a screw 18 . The screw 18 includes a shank 20 . A first area A1 of the rod portion 20 is formed with a thread 201, a second area A2 of the rod portion 20 is provided with an annular protruding portion 203, and an outer diameter of the annular protruding portion 203 is longer than an outer diameter of the rod portion 20. OD length. The screw 18 also includes an end portion 22 disposed on an end of the rod portion 20 adjacent to the second area A2. The screw mechanism 16 also includes an accommodating part 24 disposed on the supporting frame 12 . A groove 241 is formed on the accommodating member 24 , and the groove 241 is used for accommodating the annular protruding portion 203 of the screw rod 18 . The screw mechanism 16 further includes a side hole screw 26 disposed on the antenna module 14 and mounted on the first area A1 of the screw 18 . As shown in FIGS. 1 to 3 , the side hole screw 26 is used to move relative to the accommodating member 24 along the thread 201 of the screw 18 when the screw 18 rotates, so as to adjust the relative angle between the antenna module 14 and the supporting frame 12 .

In addition, the screw 18 may further include a scale 28 connected to the end 22 of the screw 18 . The dial 28 can be used to provide the user with information about the relative angle change between the antenna module 14 and the support frame 12 when the screw 18 is rotated to drive the antenna module 14 to rotate relative to the support frame 12 . The dial 28 can be integrally connected to the end 22 of the screw 18 , so as to reduce the number of components of the screw mechanism 16 , thereby reducing the manufacturing cost and assembly man-hours of the screw mechanism 16 .

To sum up, the screw mechanism 16 of the present invention is provided with an annular protruding portion 203 in the second area A2 of the screw 18 . The manner of disposing the annular protrusion 203 on the rod portion 20 of the screw 18 may be machining such as cutting, welding, or other forming methods, depending on actual needs. Correspondingly, the accommodating part 24 of the screw mechanism 16 can form a groove 241 having a size similar to that of the annular protrusion 203 of the screw 18 , so that the annular protrusion 203 can be accommodated in the groove 241 . When the user rotates the screw rod 18, the annular protrusion 203 fits closely in the groove 241 of the accommodating part 24. At this time, the annular protrusion 203 rotates in the groove 241 and slides relative to the inner wall of the groove 241. Therefore, the screw rod 18 does not produce linear displacement changes relative to the accommodating member 24 when it rotates. On the other hand, when the user turns the screw 18, the side hole screw 26 will move relative to the receiving part 24 along the thread 201 of the screw 18, so the user can adjust the antenna module 14 relative to the supporting frame 12 by turning the screw 18 to change the elevation angle or azimuth angle of the antenna module 14 .

Compared with the prior art, the present invention forms an annular protrusion on the screw with a size slightly larger than that of the rod, which means that the outer diameter of the annular protrusion is substantially greater than the outer diameter of the rod.
