Description

Technical Field

[0001] The invention belongs to the technical field of mobile communications, and in particular relates to an antenna mounting bracket. Background Art

[0002] In the field of mobile communications, the selection and configuration of base station antennas plays a crucial role in ensuring network coverage quality, balancing traffic distribution, and optimizing network service quality. Based on key factors such as network coverage requirements, traffic distribution, and network service quality, the rational selection of base station antennas is a crucial step in mobile communications network construction. The configuration of base station antennas requires consideration of not only performance indicators such as antenna type and gain, but also key parameters such as downtilt and horizontal orientation, which directly impact network coverage and communication quality.

[0003] To achieve ideal network coverage, base station antennas are typically adjusted in both pitch and horizontal angle to optimize network layout. Adjusting the pitch angle changes the vertical coverage area of ​​the antenna beam, enabling precise adjustment of signal coverage at varying distances. Adjusting the horizontal angle, on the other hand, alters the horizontal coverage direction of the antenna beam to accommodate varying geographic locations and communication needs.

[0004] However, during antenna setup, the mounting bracket, as a crucial component for supporting and adjusting the antenna, is crucial in both performance and adjustment methods. Traditional mounting brackets primarily rely on manual mechanical tilt adjustment to change the antenna's pitch and horizontal angles, enabling precise control of the antenna's coverage. Specifically, pitch adjustment typically involves fixing the antenna's lower end so that the upper end can be adjusted relative to or away from the mast, adjusting the beam coverage area. Horizontal adjustment, on the other hand, involves rotating the antenna around the mast to meet coverage requirements in different directions. While these two adjustment methods can meet most coverage requirements to a certain extent, they also present numerous limitations in practical applications.

[0005] In particular, existing mounting brackets often require manual adjustment, which is not only time-consuming and inefficient, but also requires significant maintenance effort when base station antennas are located in harsh environments such as outdoors and mountainous areas. This reliance on manual adjustment not only increases operating costs for businesses but also struggles to adapt to the rapid and flexible development of mobile communication networks.

The bracket includes a first mounting bracket, the first mounting bracket including a pitch adjustment mechanism, a first pole base for being fixed to the pole, and a first antenna base for being fixed to the antenna. The pitch adjustment mechanism includes a first rotating arm pivotally mounted to the first pole base, a second rotating arm pivotally mounted to the first antenna base, and a pitch drive assembly. The first rotating arm and the second rotating arm are pivotally mounted via the pitch drive assembly, and the pitch drive assembly is used to drive the first rotating arm or the second rotating arm to rotate relative to each other in pitch.

Furthermore, manual antenna adjustment can pose significant safety risks in certain dangerous or harsh environments (such as high altitudes or areas exposed to lightning). However, the present invention, through remote or automated adjustments, allows operations to be performed in a safe environment, eliminating human exposure to danger.

It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with their meanings in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0032] The present invention provides an antenna mounting bracket, which can receive external signals and drive a motor to adjust the pitch angle and horizontal rotation angle of the antenna, eliminating the need for manual adjustment of the pitch angle and horizontal rotation angle of the antenna, thereby reducing the maintenance cost of the antenna.

[0033] In an exemplary embodiment of the present invention, Figure 1 The antenna mounting bracket 100 is used to secure the antenna 400 to the mast 500. The antenna mounting bracket 100 includes a first mounting bracket 200 and a second mounting bracket 300. The first mounting bracket 200 and the second mounting bracket 300 are sequentially arranged along the axial direction of the mast 500. The first mounting bracket 200 is used to adjust the pitch angle of the antenna 400, and the second mounting bracket 300 is used to adjust the horizontal rotation angle of the antenna 400. In this embodiment, the first mounting bracket 200 is positioned above the second mounting bracket 300 to describe the present invention, but this should not be construed as limiting the present invention.

[0034] Combine Figure 1 and Figure 2 The first mounting bracket 200 includes a first pole mount 210, a first antenna mount 220, and a pitch adjustment mechanism, wherein the first pole mount 210 is fixedly connected to the pole 500, the first antenna mount 220 is fixedly connected to the antenna 400, and the pitch adjustment mechanism is pivotally connected to the first pole mount 210 and the first antenna mount 220 respectively. The pitch adjustment mechanism can be expanded and contracted in the pitch direction of the antenna 400, so that the antenna 400 can move in the pitch direction relative to the pole 500 to adjust the pitch angle of the antenna 400.

[0035] Specifically, the pitch adjustment mechanism includes a first rotating arm 230, a second rotating arm 240 and a pitch drive assembly, wherein the first rotating arm 230 is pivoted to the first pole base 210, and the second rotating arm 240 is pivoted to the first antenna base 220. The first rotating arm 230 and the second rotating arm 240 are pivoted to each other through the pitch drive assembly, so that the first rotating arm 230 or the second rotating arm 240 can rotate relative to each other in the pitch direction to adjust the pitch angle of the antenna 400.

[0036] Combine Figure 3 The pitch drive assembly includes a first motor 250. One end of the first rotating arm 230 (referred to as the second end 231) is enlarged to form a mounting cavity 232. The first motor 250 is mounted in the mounting cavity 232. The output shaft of the first motor 250 is drivingly connected to one end of the second rotating arm 240 (referred to as the second end 241). The first motor 250 drives the second rotating arm 240 to rotate in the pitch direction, thereby causing the first rotating arm 230 and the second rotating arm 240 to expand or contract in the pitch direction, thereby adjusting the pitch angle of the antenna 400.

[0037] In this embodiment, the mounting cavity 232 has an opening. The second end 241 of the second rotating arm 240 is enlarged to form a mounting cover 242. The mounting cover 242 covers the opening to seal the mounting cavity 232. Furthermore, the output shaft of the first motor 250 is in driving connection with the mounting cover 242. The first motor 250 drives the second rotating arm 240 to rotate via the mounting cover 242.

[0038] In one embodiment, the pitch drive assembly further includes a reducer (referred to as a first reducer 260). The first reducer 260 is disposed between the first motor 250 and the mounting cover 242. The first reducer 260 is connected to the output shaft of the first motor 250 and the mounting cover 242, respectively, so that the first motor 250 drives the second rotating arm 240 to rotate via the first reducer 260.

[0039] The first reducer 260 increases the torque of the output shaft of the first motor 250 by reducing speed, which means that the rotational speed is reduced, but the pitch drive assembly can generate a greater force to drive the second rotating arm 240 to rotate. Especially when the antenna 400 is heavy, the first reducer 260 can drive the second rotating arm 240 to rotate to adjust the pitch angle of the antenna 400. In addition, the first reducer 260 can reduce the impact and load on the first motor 250 and extend the service life of the first motor 250. At the same time, the first reducer 260 can also reduce the vibration and noise of the pitch drive assembly, improve the smoothness of operation, and thus improve the operating accuracy, so as to facilitate the precise adjustment of the pitch angle.

[0040] The pitch drive assembly also includes an electromagnetic brake (referred to as the first electromagnetic brake 270). The first electromagnetic brake 270 and the first reducer 260 are located on either side of the first motor 250. The first electromagnetic brake 270 uses electromagnetic force to apply mechanical resistance (friction) to slow or stop the movement of the first motor 250. By configuring the first electromagnetic brake 270, the pitch drive assembly can be ensured to stop quickly and safely if the first motor 250 unexpectedly loses control or needs to be stopped immediately, thereby avoiding possible accidents and damage. In addition, the first motor 250 generates significant impact and load during startup and shutdown. The first electromagnetic brake 270 can help the first motor 250 start smoothly during startup, reducing startup shock; when stopping, it can reduce the load on the first motor 250, extending the service life of the first motor 250 and the first reducer 260.

[0041] In an exemplary embodiment of the present invention, the pitch drive assembly further includes a pitch control assembly, which includes a pitch control unit (not shown). The pitch control unit is electrically connected to the first motor 250, the first reducer 260, and the first electromagnetic brake 270, respectively. The pitch control unit is configured to control the operation of the first motor 250, the first reducer 260, and the first electromagnetic brake 270 so that the first motor 250, the first reducer 260, and the first electromagnetic brake 270 work together to effectively drive the second rotating arm 240 to rotate, thereby facilitating accurate adjustment of the pitch angle of the antenna 400. In this embodiment, it is recommended that the pitch control unit be a chip or a single-chip microcomputer, but this should not be construed as limiting the present invention.

[0042] In this embodiment, combined with Figure 4 The pitch control unit is provided with a communication interface (referred to as the first communication interface 281). The first communication interface 281 is electrically connected to an external device via a cable, so that the external device can output a first control signal to the pitch control unit. The pitch control unit parses the first control signal to obtain corresponding pitch adjustment angle data. The pitch control unit controls the operation of the first motor 250, the first reducer 260, and the first electromagnetic brake 270 based on the pitch adjustment angle data to adjust the pitch angle of the antenna 400 accordingly. It is understood that the first mounting bracket 200 can be remotely controlled by the external device, and the pitch angle of the antenna 400 can be adjusted by the first mounting bracket 200, thereby reducing labor costs and improving antenna adjustment efficiency. In this embodiment, it is recommended that the first communication interface 281 is an AISG interface, but this should not be understood as a limitation of the present invention.

[0043] In one embodiment, the pitch control component also includes a communication unit (referred to as a first communication unit, not shown), and the pitch control unit is wirelessly connected to an external device via the first communication unit, so that the pitch control unit can wirelessly receive a first control signal output by the external device to adjust the pitch angle of the antenna 400.

[0044] In one embodiment, combined Figure 4 The pitch control assembly is integrated on a circuit board (the circuit board is referred to as the first circuit board 280 ). The first rotating arm 230 is provided with a receiving groove 233 , and the first circuit board 280 is installed in the receiving groove 233 . Figure 2 A cover plate 234 is further provided corresponding to the accommodating groove 233. The cover plate 234 covers the notch of the accommodating groove 233 to seal the accommodating groove 233, protect the first circuit board 280 installed in the accommodating groove 233, prevent the electronic components on the first circuit board 280 from being damaged, and extend the service life of the pitch control component.

[0045] In one embodiment, combined Figure 2 and Figure 3 The pitch adjustment mechanism also includes a limit ring (referred to as a first limit ring 290), and the first limit ring 290 is arranged between the opening of the mounting cavity 232 and the mounting cover 242. In this embodiment, the first limit ring 290 is fixed on the opening of the mounting cavity 232, and the mounting cover 242 is arranged on the first limit ring 290 to close the mounting cavity 232.

[0046] In this embodiment, a sliding groove (referred to as a pitch sliding groove 291) is defined on the first limiting ring 290. The pitch sliding groove 291 extends along the first limiting ring 290 in the pitch direction of the antenna 400. The mounting cover 242 is provided with a limiting portion (referred to as a pitch limiting portion 243). The pitch limiting portion 243 protrudes toward the first limiting ring 290 and is inserted into the pitch sliding groove 291.

[0047] During the process of the pitch drive assembly driving the second rotating arm 240 to rotate via the mounting cover 242, the mounting cover 242 will drive the pitch limiting portion 243 to rotate. Since the pitch limiting portion 243 is inserted into the pitch slide groove 291, the pitch limiting portion 243 will move along the extension path of the pitch slide groove 291, thereby limiting the rotation stroke of the pitch limiting portion 243 through the pitch slide groove 291, thereby controlling the rotation stroke of the second rotating arm 240, and further controlling the pitch stroke of the antenna 400, so that the pitch inclination angle of the antenna 400 is limited to avoid the pitch inclination angle being too large or too small.

[0048] In an exemplary embodiment of the present invention, Figure 1 The second mounting bracket 300 is used to control the horizontal rotation angle of the antenna 400. The second mounting bracket 300 includes a second pole mount 310, a second antenna mount 320, and a horizontal adjustment mechanism. The second pole mount 310 is fixed to the pole 500, and the second antenna mount 320 is fixed to the antenna 400. The horizontal adjustment mechanism is pivotally mounted to the second pole mount 310 and the second antenna mount 320, respectively. The horizontal adjustment mechanism can drive the antenna 400 to rotate horizontally via the second antenna mount 320 to adjust the horizontal rotation angle of the antenna 400.

[0049] Specifically, combined Figure 1 and Figure 5 The horizontal adjustment mechanism includes a third rotating arm 330 and a horizontal drive assembly. One end of the third rotating arm 330 (referred to as the first end 331) is connected to the second mast mount 310 and pivotally connected to the second mast mount 310. The other end of the third rotating arm 330 (referred to as the second end 335) is pivotally connected to the second antenna mount 320. The horizontal drive assembly is used to drive the third rotating arm 330 to rotate horizontally relative to the second mast mount 310, so that the third rotating arm 330 drives the antenna 400 to rotate horizontally via the second antenna mount 320 to adjust the horizontal rotation angle of the antenna 400.

[0050] In this embodiment, combined with Figure 6 The second mast mount 310 defines a mounting hole 311, and the first end 331 of the third rotating arm 330 is positioned directly above the mounting hole 311. The horizontal drive assembly includes a motor (referred to as a second motor 340). The second motor 340 is positioned in the mounting hole 311, with the output shaft of the second motor 340 facing the first end 331 of the third rotating arm 330. The output shaft of the second motor 340 is in driving connection with the first end 331 of the third rotating arm 330, so that the second motor 340 drives the third rotating arm 330 to rotate horizontally, thereby driving the antenna 400 to rotate horizontally through the third rotating arm 330.

[0051] In one embodiment, the horizontal drive assembly further includes a reducer (referred to as a second reducer 350). The second reducer 350 is installed in the mounting hole 311 and is disposed between the second motor 340 and the first end 331 of the third rotating arm 330. The second reducer 350 is respectively in transmission connection with the second motor 340 and the third rotating arm 330. In other words, the second motor 340 drives the third rotating arm 330 to rotate via the second reducer 350. The function of the second reducer 350 is the same as that of the first reducer 260 described above, and will not be described in detail here to save space.

[0052] The horizontal drive assembly also includes an electromagnetic brake (referred to as a second electromagnetic brake 360). The second electromagnetic brake 360 ​​and the second reducer 350 are located on either side of the second motor 340. The second electromagnetic brake 360 ​​uses electromagnetic force to apply mechanical resistance (friction) to slow or stop the movement of the second motor 340. Specifically, the function of the second electromagnetic brake 360 ​​is the same as that of the first reducer 260 described above and will not be further described here to save space.

[0053] In this embodiment, the horizontal drive assembly also includes a sleeve 332, which is arranged on the second holding rod seat 310, and the sleeve 332 and the third rotating arm 330 are respectively arranged on both sides of the second holding rod seat 310. The sleeve 332 is used to sleeve the second motor 340 and the second electromagnetic brake 360 ​​of the horizontal drive assembly, and the opening of the sleeve 332 is connected to an opening of the mounting hole 311 to close the sleeve 332 and protect the second motor 340 and the second electromagnetic brake 360 ​​from external damage.

[0054] The horizontal drive assembly also includes a horizontal control assembly, which includes a horizontal control unit (not shown). The horizontal control unit is electrically connected to the second motor 340, the second reducer 350, and the second electromagnetic brake 360. The horizontal control unit is used to control the operation of the second motor 340, the second reducer 350, and the second electromagnetic brake 360 ​​so that the second motor 340, the second reducer 350, and the second electromagnetic brake 360 ​​work together to effectively drive the third rotating arm 330 to rotate, thereby facilitating accurate adjustment of the horizontal rotation angle of the antenna 400. In this embodiment, it is recommended that the horizontal control unit be a chip or a single-chip microcomputer, but this should not be construed as a limitation of the present invention.

[0055] In this embodiment, the horizontal control unit is provided with a communication interface (referred to as a second communication interface, not shown). The second communication interface is electrically connected to an external device via a cable so that the external device can output a second control signal to the horizontal control unit. The horizontal control unit parses the second control signal to obtain corresponding horizontal adjustment angle data. The horizontal control unit controls the operation of the second motor 340, the second reducer 350, and the second electromagnetic brake 360 ​​based on the horizontal adjustment angle data to adjust the horizontal rotation angle of the antenna 400 accordingly. It is understood that the second mounting bracket 300 can be remotely controlled by the external device, and the horizontal rotation angle of the antenna 400 can be adjusted by the second mounting bracket 300, thereby reducing labor costs and improving adjustment efficiency. In this embodiment, it is recommended that the second communication interface be an AISG interface, but this should not be understood as limiting the present invention.

[0056] In one embodiment, the horizontal control component also includes a communication unit (referred to as a second communication unit, not shown), and the horizontal control unit is wirelessly connected to an external device via the second communication unit, so that the horizontal control unit can wirelessly receive a second control signal output by the external device to adjust the horizontal angle of the antenna 400.

[0057] In one embodiment, combined Figure 6 The horizontal control component is integrated on a circuit board (the circuit board is called the second circuit board 370 ), and a receiving cavity 333 is provided on the third rotating arm 330 , and the second circuit board 370 is installed in the receiving cavity 333 .

[0058] In one embodiment, combined Figure 5 and Figure 6 The horizontal drive assembly further includes a retaining ring (referred to as a second retaining ring 380). The second retaining ring 380 is disposed on one side of the second pole base 310 and is disposed on the same side of the second pole base 310 as the first end 331 of the third rotating arm 330. The second retaining ring 380 is disposed between the third rotating arm 330 and the second pole base 310 and is fixedly connected to the second pole base 310.

[0059] The second limiting ring 380 is provided with a horizontal sliding groove 381, which extends along the horizontal rotation direction of the antenna 400. The third rotating arm 330 is provided with a horizontal limiting portion 334, which protrudes toward the second limiting ring 380 and is slidably inserted into the horizontal sliding groove 381.

[0060] During the rotation of the third rotating arm 330, since the horizontal limit part 334 is inserted into the horizontal slide groove 381, the horizontal limit part 334 will move along the extension path of the horizontal slide groove 381, thereby limiting the rotation stroke of the horizontal limit part 334 through the horizontal slide groove 381, thereby controlling the rotation stroke of the third rotating arm 330, and then controlling the horizontal stroke of the antenna 400, so as to control the horizontal rotation angle of the antenna 400 and avoid the horizontal rotation angle being too large or too small.

[0061] In a further embodiment, in combination Figure 5 The second limiting ring 380 is provided with an angle scale 382, ​​which corresponds to the angle of the horizontal slide slot 381. When manually adjusting the horizontal angle of the antenna 400, the angle scale 382 can be used to align the horizontal angle of the antenna 400. In this embodiment, assuming the horizontal angle range of the antenna 400 is between -45° and +45°, the angle scale 382 also ranges between -45° and +45°.

[0062] In one embodiment, combined Figure 1 The antenna mount 100 also includes a positioning shaft 110. The first mast mount 210 is provided with a positioning hole (referred to as a first positioning hole, not shown). The second mast mount 310 is also provided with a positioning hole (referred to as a second positioning hole, not shown). The ends of the positioning shaft 110 are respectively inserted into the first and second positioning holes, thereby connecting the first mounting frame 200 and the second mounting frame 300. This improves the structural stability of the antenna mount 100, enhances the stability of the first mounting frame 200 when adjusting the pitch angle of the antenna 400, and enhances the stability of the second mounting frame 300 when adjusting the horizontal tilt angle of the antenna 400. In another embodiment, the second positioning hole is provided on the first end 331 of the third rotating arm 330.

[0063] To sum up, the antenna mounting bracket of the present invention controls the first mounting bracket to automatically adjust the pitch angle of the antenna, and controls the second mounting bracket to automatically adjust the horizontal rotation angle of the antenna. There is no need to manually adjust the pitch angle and horizontal rotation angle of the antenna, thereby reducing labor costs and improving antenna maintenance efficiency.
