Description

Technical Field

[0001] This application relates to the field of mobile communication technology, and in particular to a base station antenna. Background Technology

[0002] The accuracy of the horizontal azimuth angle of mobile communication base station antennas has a significant impact on network planning and optimization. Network planners need to use the azimuth angle information of each cell to predict antenna signal coverage and capacity for each cell via base station antennas. Network optimization personnel also need to use engineering parameters such as horizontal azimuth angle during drive testing to make accurate judgments on neighboring cell information and co-channel interference during the testing process.

[0003] A base station antenna typically consists of a base plate and a reflector fixed above the base plate. The reflector radiates the antenna signal to enable mobile communication devices, such as mobile phones, to function properly. The reflector is often angled upwards on the top surface of the base plate to form a specific horizontal azimuth angle. However, because the reflector is fixedly connected to the base plate, meaning the horizontal azimuth angle between them is constant, the antenna's radiation range is also fixed. This limits the antenna's signal coverage and cannot meet the needs of network planners and optimizers who require adjustments to the horizontal azimuth angle. Summary of the Invention

[0038] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0040] Reference Figures 1 to 8 As shown, this embodiment provides a base station antenna. The base station antenna specifically includes a support base 1, a reflector 2, and a driving structure 3. The reflector 2 is mounted on the support base 1 and can rotate relative to the support base 1 about a horizontal axis. Specifically, the horizontal axis is... Figure 1 The XX direction is shown.

[0041] For example, refer to Figures 1 to 3 As shown, a radiating element 211 is provided on one side of the reflector 2, and the radiating element 211 is used to radiate the antenna signal. The side of the reflector 2 with the radiating element is formed as a radiating surface, and the side of the reflector 2 without the radiating element 211 is formed as a non-radiating surface.

[0042] A connector 4 is provided between the driving structure 3 and the reflector 2. One end of the connector 4 is rotatably connected to the driving structure 3, and the other end is rotatably connected to the reflector 2. The driving structure 3 can reciprocate along the horizontal axis to drive the connector 4 to rotate, causing the reflector 2 to rotate relative to the support base 1, thereby adjusting the horizontal azimuth angle of the reflector 2's radiation surface. Specifically, the horizontal azimuth angle refers to... Figure 3 S is shown.

[0043] Reference Figures 1 to 3 As shown, for example, the support base 1 can include a base 11 and a support plate 12 that is perpendicular to the base 11. For example, the reflector 2 can be rotatably connected to the upper end of the support plate 12. For example, the reflector 2 can also be rotatably connected to the lower end of the support plate 12 or connected to other positions on the support plate 12.

[0044] This allows for adjustment of the horizontal azimuth angle between the reflector 2 and the support base 1, thereby regulating the radiation range of the antenna signal provided by the reflector 2. For example, the reflector 2 can be rotated via the drive structure 3 and connector 4 to adjust its radiation range to suit different densely populated areas. This allows for flexible adjustment of the antenna signal radiation range based on varying usage requirements. For instance, during peak commuting hours, the reflector 2 can be rotated to cover densely populated areas such as subway stations; conversely, at other times, it can be rotated to cover densely populated areas such as office buildings and residential areas. This expands the antenna signal's radiation range to some extent, reducing its limitations and improving the flexibility and practicality of the base station antenna, ultimately enhancing the user's communication quality.

[0045] The base station antenna provided in this embodiment, by setting a driving structure 3, allows the reflector 2 to rotate relative to the support base 1 around a horizontal axis. A connector 4 is set between the driving structure 3 and the reflector 2, with one end of the connector 4 rotatably connected to the driving structure 3 and the other end rotatably connected to the reflector 2. Simultaneously, the driving structure 3 can reciprocate along the horizontal axis to drive the connector 4 to rotate, causing the reflector 2 to rotate relative to the support base 1, thereby adjusting the horizontal azimuth angle of the reflector 2's radiation surface. This configuration, by adjusting the horizontal azimuth angle, allows the reflector 2 to adjust the radiation range of the antenna signal. This facilitates network planners and network optimizers to adjust the horizontal azimuth angle according to actual needs, thereby adjusting the antenna signal radiation range. To a certain extent, this expands the radiation range of the base station antenna, reduces the limitations of the antenna signal radiation range, improves the flexibility and practicality of the base station antenna, and contributes to improving communication quality.

[0046] In some embodiments, refer to Figures 1 to 3 As shown, both the drive structure 3 and the connector 4 are located on the side of the reflector 2 opposite to the radiating surface. That is, the drive structure 3 and the connector 4 are located on the non-radiating surface of the reflector 2.

[0047] This configuration ensures that the horizontal azimuth angle of the reflector 2 can be adjusted to change the radiation range of the antenna signal, while also preventing the driving structure 3 and the connector 4 from affecting the normal radiation of the reflector 2 to a certain extent, thus further guaranteeing the communication quality and the radiation range of the antenna signal.

[0048] In some embodiments, refer to Figures 1 to 8 As shown, the drive structure 3 includes a driving member 31 and a driven member 32. The driving member 31 has a main drive tooth, and the driven member 32 has a driven tooth that meshes with the main drive tooth. The driving member 31 can rotate relative to the support base 1 to drive the driven member 32 to move along the horizontal axis. One end of the connecting member 4 is rotatably connected to the driven member 32.

[0049] With this configuration, by controlling the rotation of the driving member 31, the driven member 32 can move along the horizontal axis under the drive of the driving member 31 due to the matching meshing of the main drive gear and the driven gear. This realizes the rotation of the reflector 2 relative to the support base 1, adjusts the horizontal azimuth angle of the reflector 2, and expands the radiation range of the reflector 2 to a certain extent.

[0050] In some embodiments, refer to Figure 4 and Figure 5As shown, the driving member 31 includes a screw, the external thread of which forms the main transmission teeth. The driven member 32 includes a transmission rod 322 and a nut 321 fixedly connected to the transmission rod 322. The nut 321 is sleeved on the outer circumference of the screw, and the internal thread of the nut 321 forms the driven teeth. The transmission rod 322 extends in a direction parallel to the horizontal axis. One end of the connecting member 4 is rotatably connected to the transmission rod 322.

[0051] With this configuration, when the control screw rotates, the nut 321 can move along the horizontal axis under the drive of the screw, and drive the transmission rod 322 to move, allowing the connecting piece 4 and the reflector 2 to rotate, thereby achieving adjustment of the horizontal azimuth angle. This makes the drive structure 3 simple in structure, low in manufacturing cost, and achieves the effect of small torque input and large thrust output, improving the reliability of the reflector 2 rotation and stabilizing the adjustment of the horizontal azimuth angle.

[0052] For example, nut 321 may be a single nut or a combination of a nut and other connecting parts.

[0053] Of course, in other embodiments, the driving member 31 may also be a driving gear, and the driven member 32 may be a rack that meshes with the outer gear teeth of the driving gear, and the extending direction of the rack is parallel to the extending direction of the horizontal axis.

[0054] In some embodiments, refer to Figure 4 and Figure 5 As shown, a guide seat 5 is provided on the support base 1, and a guide hole 51 is provided on the guide seat 5. The transmission rod 322 passes through the guide hole 51 and can move along the guide hole 51.

[0055] This design can, to some extent, prevent the transmission rod 322 from deviating during its movement, thus improving the stability of its movement and ensuring the stability of the reflector 2's rotation. This also ensures stable and reliable adjustment of the horizontal azimuth angle and the antenna signal's radiation range. Furthermore, it can prevent the nut 321 from rotating together with the screw, guaranteeing the stability of the driven member 32 as it moves parallel to the horizontal axis, further ensuring stable adjustment of the horizontal azimuth angle.

[0056] In some embodiments, refer to Figure 4 and Figure 5 As shown, there are at least two guide seats 5, and at least two guide seats 5 are arranged at intervals on the support seat 1 in a direction parallel to the horizontal axis.

[0057] This configuration allows the movement of the transmission rod 322 to be guided at different positions on the support base 1, thereby improving the guiding effect of the transmission rod 322, further enhancing the stability and reliability of the driven member 32 during movement, and further improving the stability and reliability of the reflector 2 rotating to adjust the radiation range.

[0058] In some embodiments, refer to Figures 1 to 4 As shown, the base station antenna also includes a control device, and a drive component 6 is also provided on the support base 1. The drive component 6 is connected to the active component 31 for driving the active component 31 to rotate. The control device is electrically connected to the drive component 6 and is used to control the working state of the drive component 6.

[0059] By setting the driving component 6, when the driving component 6 is working, the active component 31 is driven by the driving component 6 to rotate, and the driven component 32 moves in a direction parallel to the horizontal axis, and drives the connecting component 4 to rotate, so that the reflector 2 rotates relative to the support base 1, thereby adjusting the horizontal azimuth angle of the radiation surface of the reflector 2.

[0060] For example, the driving component 6 can be a drive motor, and the output shaft of the drive motor can be connected to the driving component 31 to drive the driving component 31 to rotate. This configuration improves the ease of rotation of the driving component 31, saves manpower to a certain extent, and facilitates the adjustment of the radiation range.

[0061] Of course, in other embodiments, the driving member 31 can also be rotated by manually turning the driving member 31.

[0062] The operating state of the drive unit 6 can be adjusted by setting up the aforementioned control device. The operating state of the drive unit 6 includes, for example, starting operation and stopping operation. When the drive unit 6 starts operation, it can drive the reflector 2 to rotate to adjust the radiation range.

[0063] This configuration facilitates remote control of the rotation of reflector 2 based on actual antenna signal radiation requirements, thereby achieving remote intelligent control of the radiation range. This improves the efficiency of adjusting the radiation range of the operator's base station antenna and results in high layout efficiency for the base station antenna. For example, the control device could be a control button, a remote control, etc.

[0064] Of course, in other embodiments, the drive structure 3 can also be a drive cylinder. For example, when the base station antenna also includes a control device, the control device can be electrically connected to the drive cylinder to control the extension and retraction of the piston rod of the drive cylinder.

[0065] In some embodiments, refer to Figures 1 to 8As shown, a first rotating head 41 is provided at one end of the connector 4. A first engaging groove 3231 is provided on the drive structure 3 with the opening facing the first rotating head 41. The first rotating head 41 is engaged in the first engaging groove 3231 and can rotate within the first engaging groove 3231.

[0066] This configuration enables a rotational connection between the connector 4 and the drive structure 3, and allows for flexible and smooth relative rotation between the connector 4 and the drive structure 3. This improves the efficiency of the connector 4 when rotating relative to the drive structure 3, resulting in high efficiency when adjusting the radiation range.

[0067] In a specific implementation, the driven member 32 also includes a first bearing seat 323 disposed on the transmission rod 322. For example, a first snap-fit ​​groove 3231 can be disposed on the first bearing seat 323. The structure of the first bearing seat 323 is similar to... Figure 6 The structure of the second bearing housing 22 is the same.

[0068] In some embodiments, refer to Figures 1 to 8 As shown, the other end of the connector 4 is provided with a second rotating head 42. The reflector 2 is provided with a second locking groove 221 with the opening facing the second rotating head 42. The second rotating head 42 is locked in the second locking groove 221 and can rotate within the second locking groove 221.

[0069] This configuration enables a rotatable connection between the connector 4 and the reflector 2, and allows for smooth and flexible relative rotation between the connector 4 and the reflector 2. This improves the efficiency of the connector 4 in driving the reflector 2 to rotate, resulting in high efficiency in adjusting the radiation range.

[0070] In a specific implementation, the reflector 2 includes a plate body 21 and a second bearing seat 22 disposed on the plate body 21, and a second snap-fit ​​groove 221 is disposed on the second bearing seat 22. The aforementioned radiating element 211 is specifically disposed on the plate body 21.

[0071] In some embodiments, refer to Figures 1 to 5 As shown, the drive structure 3 is provided with a mounting base 7, which is detachably connected to the support base 1 to connect the drive structure 3 to the support base 1.

[0072] This design facilitates a detachable connection between the drive structure 3 and the support base 1 via the mounting bracket 7. If either the support base 1 or the drive structure 3 is damaged, only the damaged component needs to be replaced, thus avoiding the scrapping of the entire support base 1 and drive structure 3 and saving on maintenance and usage costs.

[0073] Moreover, the above-mentioned setup can also achieve the integrated assembly design of the drive structure 3 and the reflector 2 on the support base 1 to a certain extent, which facilitates the standardized and automated assembly of the entire base station antenna, improves the assembly efficiency of the drive structure 3 and the support base 1, and reduces labor and other costs during assembly to a certain extent.

[0074] For example, the mounting base 7 and the support base 1 can be detachably connected, for example, by screws, clips, or other means. (See reference...) Figure 4 and Figure 5 As shown, the guide seat 5 is specifically mounted on the mounting base 7.

[0075] In some embodiments, refer to Figures 1 to 5 As shown, there are at least two reflectors 2, arranged at intervals on the support base 1. There are at least two drive structures 3, with one drive structure 3 corresponding to one reflector 2. Each drive structure 3 has at least one connector 4 between itself and its corresponding reflector 2.

[0076] With this configuration, the corresponding reflector 2 is rotated by the drive structure 3 to adjust the horizontal azimuth angle of the corresponding reflector 2, thereby realizing the independent adjustment of the radiation range of each reflector 2, which makes it easy to rotate the corresponding reflector 2 according to the specific radiation range requirements.

[0077] For example, in a specific implementation, each driving structure 3 can operate independently to adjust the horizontal azimuth angle of its corresponding reflector 2. Of course, each driving structure 3 can also be controlled to operate simultaneously.

[0078] For example, refer to Figure 1 and Figure 3 As shown, for example, there can be two reflectors 2, and the radiating surfaces of the two reflectors 2 can be set opposite to each other to form a dual-sector base station antenna.

[0079] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
