Description

Technical Field

[0001] This invention relates to the field of communication equipment technology, and more particularly to an intelligent adjustable base station antenna. Background Technology

[0002] In modern mobile communication network design, base station antennas, as a critical component, require comprehensive consideration of factors such as network coverage, traffic distribution, anti-interference capabilities, and service quality to achieve scientific selection and rational deployment. Simultaneously, communication systems place higher demands on the pointing accuracy of antenna patterns. Currently, most base station antennas have fixed radiation patterns after installation. If beam pointing needs adjustment to adapt to changes in service area and optimize signal quality, the traditional approach is to manually adjust the installation orientation between the antenna and the mast. However, such operations typically require personnel to climb the tower, which is not only costly but also difficult to guarantee in terms of adjustment accuracy, making it unsuitable for the needs of dynamic network optimization and refined coverage.

[0003] The new smart base station antenna allows for independent rotation of the reflector via an azimuth adjustment system, enabling azimuth adjustment without requiring personnel to climb the tower. However, the rotation of the reflector causes a change in the phase position between the main feed point and the connector fixed to the end cap, pulling on the RF coaxial cable and causing it to bend periodically. This repetitive mechanical deformation can lead to cable cracking, resulting in RF faults such as passive intermodulation and deterioration of the VSWR, ultimately causing antenna failure. Simultaneously, the force generated by the cable bending and deformation can hinder the reflector's rotation, even causing rotational failure.

[0004] Therefore, it is necessary to design an intelligent adjustment base station antenna to solve the above problems. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention aims to provide an intelligent adjustable base station antenna that, while enabling the reflector assembly to automatically rotate and adjust its azimuth angle, effectively solves the problem of fatigue cracking of radio frequency cables caused by repeated bending in traditional solutions.

[0006] To achieve the above objectives, the present invention provides an intelligent adjustable base station antenna, comprising: Reflector assembly; An end cap assembly is disposed at the end of the reflector assembly; The rotating bracket has a hollow shaft, and a cable routing tube extending along its axial direction is provided inside the hollow shaft. The cable passes through the cable routing tube, one end of the cable is connected to the phase shifter main feed point of the reflector assembly, and the other end is connected to the main feed connector fixed to the end cover assembly. A drive component, connected to the rotating bracket, is used to drive the rotating bracket to rotate the reflector assembly.

[0007] In some embodiments, the rotating support further includes: Fixed bracket, used for fixed connection to the pole via mounting bracket; The mounting plate is fixedly connected to the reflector assembly; A bushing is provided, through which the hollow shaft is rotatably inserted into the hole of the fixed bracket, and one end of the hollow shaft is fixedly connected to the mounting plate.

[0008] In some embodiments, the drive assembly includes a first drive mechanism connected to the hollow shaft for driving the hollow shaft to rotate relative to the fixed bracket; The first drive mechanism includes a motor, a worm gear, and a gear. The gear is sleeved on the hollow shaft and is linked to the hollow shaft. The worm gear meshes with the gear. The motor drives the worm gear to rotate, thereby driving the gear and the hollow shaft to rotate. The gear is provided with a boss, and the hollow shaft is provided with a limiting groove. The gear is mated to the hollow shaft through the matching fit between the boss and the limiting groove.

[0009] In some implementations, a locking mechanism is also included; The locking mechanism is located at the end of the reflector assembly and is used to lock the reflector assembly in its rotational position after it has rotated to a set azimuth angle.

[0010] In some embodiments, the locking mechanism includes: a rotating assembly and a locking assembly; The rotating assembly includes a rotating shaft, which is rotatably mounted in the fixed bracket of the rotating bracket via a bushing, and one end of the rotating shaft is connected to the mounting plate. The locking assembly is disposed between the rotating shaft and the fixed bracket to achieve relative locking or release between the two.

[0011] In some embodiments, the locking assembly includes: A locking stop is fixed to the end face of the fixed bracket; A stop disc is axially movable and mounted on the rotating shaft; The paddle is connected to the stop plate in a driving manner; A reset element is disposed on the rotating shaft; The screw is threadedly engaged with the paddle. When the screw rotates, it drives the paddle to move axially, thereby driving the stop plate to engage or disengage from the lock.

[0012] In some embodiments, the rotating shaft is provided with a plurality of axially extending guide posts, and the stop plate is provided with a plurality of guide holes corresponding to the guide posts, which are inserted into the guide holes to guide and limit the axial movement of the stop plate.

[0013] In some embodiments, the locking stop is provided with a protrusion and the stop plate is provided with a groove. When the protrusion engages with the groove, the locking mechanism is in a locked state. When the protrusion separates from the groove, the locking mechanism is in a rotatable state. The locking assembly further includes a locking cover and a guide shaft. The locking cover is fixedly connected to the stop plate, and the guide shaft is arranged axially to provide guidance for the axial movement of the paddle.

[0014] In some embodiments, the drive assembly further includes a second drive mechanism connected to the locking mechanism for driving the locking mechanism to perform locking or unlocking actions.

[0015] In some implementations, a radome and a support assembly are also included; The support assembly includes an antenna radome support and a support base. The antenna radome support is used to support the antenna radome, and the support base is disposed at the cantilever end of the antenna radome support to provide auxiliary support for the antenna radome support.

[0016] Compared with the prior art, the intelligent adjustment base station antenna provided by the present invention has the following beneficial effects: In this invention, the central axis of the rotating bracket is set as a hollow shaft, and a cable routing tube is installed inside the hollow shaft. The main feeder connector is fixed to the end cover, and the cable runs through the cable routing tube. One end of the cable is welded and fixed to the main feed point of the phase shifter of the reflector assembly. When the reflector assembly rotates relative to the end cover, the relative position of the main feed point of the phase shifter and the main feeder connector changes. Since the cable passes through the hollow shaft, the cable length remains constant during the rotation of the reflector assembly, avoiding the cable being pulled during rotation. This effectively avoids the cable from being bent and cracked multiple times, improves the service life of the cable harness, and also effectively avoids the phenomenon of increased rotational resistance of the reflector caused by cable bending.

[0017] In addition, a rotating bracket is provided at the end of the reflector assembly. The rotating bracket is equipped with a locking device, which can realize the locking function of the rotating bracket through the RET power unit, effectively reducing the problem of reflector swaying and improving the azimuth angle maintenance and accuracy.

Detailed Implementation

[0021] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0022] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, to facilitate understanding, in some figures, only one of components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0023] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0024] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] In one embodiment, refer to the appendix to the specification. Figures 1 to 3 The present invention provides an intelligent adjustable base station antenna, comprising: a reflector assembly 1, an end cap assembly 2, a rotating bracket 3, and a drive assembly 4; the end cap assembly 2 is disposed at the end of the reflector assembly 1; the rotating bracket 3 has a hollow shaft 35, and a cable conduit 34 extending axially within the hollow shaft 35, a cable 11 passing through the cable conduit 34, one end of the cable 11 being connected to the phase shifter main feed point 14 of the reflector assembly 1, and the other end being connected to the main feed connector 12 fixed to the end cap assembly 2; the drive assembly 4 is connected to the rotating bracket 3 and is used to drive the rotating bracket 3 to rotate the reflector assembly 1.

[0027] In this embodiment, the hollow shaft 35 of the rotating bracket 3 is provided with a cable conduit 34 coaxial with the rotation center, and the cable 11 is passed through the cable conduit 34. When the reflector assembly 1 rotates relative to the end cover assembly 2, although the relative position between the phase shifter main feed point 14 and the main feed connector 12 changes, the cable 11 always runs along the axis of the rotation center, and its path length remains constant, which avoids the cable 11 being repeatedly pulled or bent during the rotation. This not only improves the service life of the cable 11 and reduces the risk of radio frequency failure caused by the cracking of the cable 11, but also eliminates the mechanical resistance generated by the bending and deformation of the cable 11 on the rotation of the reflector assembly 1, ensuring the smoothness and reliability of the azimuth angle adjustment.

[0028] In one embodiment, refer to the appendix to the specification. Figure 1 The base station antenna has an antenna cover 7, and components such as the reflector assembly 1, rotating bracket 3, and drive assembly 4 are all housed inside the antenna cover 7. The end cap assembly 2 includes an upper end cap 21 and a lower end cap 22, which are respectively located at both ends of the antenna cover 7. The base station antenna as a whole is fixedly connected to the mounting pole 71 via a mounting bracket 72, thereby realizing the installation of the base station antenna.

[0029] Reference manual attached Figure 2The reflector assembly 1 is disposed inside the radome 7, with its two ends connected to the upper end cover 21 and the lower end cover 22, respectively. The reflector assembly 1 is equipped with a phase shifter 13, which has a main feed point 14. The lower end cover 22 is equipped with a main feed connector 12. A cable 11 is run through a conduit 34, with one end of the cable 11 soldered to the main feed point 14 and the other end connected to the main feed connector 12. When the reflector assembly 1 rotates relative to the lower end cover 22, the phase position of the main feed point 14 and the main feed connector 12 changes. Since the cable 11 passes through the hollow shaft 35, the length of the cable 11 remains constant during the rotation of the reflector assembly 1, preventing the cable 11 from being pulled during rotation. This effectively avoids repeated bending and cracking of the cable 11, improving its service life. Simultaneously, it effectively prevents the increase in rotational resistance of the reflector assembly 1 due to cable bending, enhancing structural reliability.

[0030] Reference manual attached Figure 3 , Figure 4 Two rotating brackets 3 are provided, located at both ends of the reflector assembly 1, and connected by a support shaft 63. Together with the reflector assembly 1, the two rotating brackets 3 are securely installed. A support assembly 6 is also provided inside the radome 7. The support assembly 6 includes a radome support 61 and a support base 62. The radome support 61 supports the radome 7, and the support base 62 is located at the cantilever end of the radome support 61, providing auxiliary support for the radome support 61. This effectively strengthens the structure at low cost and significantly reduces the problem of large deformation displacement of the radome 7 under axial force.

[0031] In one embodiment, refer to the appendix to the specification. Figure 5 The rotating bracket 3 also includes a fixed bracket 31, a mounting plate 32, and a bushing 33. The fixed bracket 31 is used to fix the mounting rod 71 to the mounting bracket 72. The mounting plate 32 is fixedly connected to the reflector assembly 1. The hollow shaft 35 is rotatably inserted into the hole of the fixed bracket 31 through the bushing 33, and one end of the hollow shaft 35 is fixedly connected to the mounting plate 32. The fixed bracket 31 serves as the base structure of the entire rotating bracket 3. It is fixedly connected to the mounting rod 71 through the mounting bracket 72, ensuring the stability of the overall antenna installation. The hollow shaft 35 is rotatably inserted into the hole of the fixed bracket 31 through the bushing 33, achieving low-friction and high-precision rotational fit, effectively reducing wear and shaking during rotation. At the same time, one end of the hollow shaft 35 is fixedly connected to the mounting plate 32, and the mounting plate 32 is fixedly connected to the reflector assembly 1, forming a reliable transmission path.

[0032] Reference manual attached Figures 6 to 8The drive assembly 4 includes a first drive mechanism 41, which is connected to the hollow shaft 35 and is used to drive the hollow shaft 35 to rotate relative to the fixed bracket 31. The first drive mechanism 41 includes a motor 411, a worm gear 412, and a gear 413. The top of the gear 413 is provided with a mating groove 4131, and the bottom of the hollow shaft 35 is inserted into the mating groove 4131. The worm gear 412 meshes with the convex teeth on the side of the gear 413. The motor 411 drives the worm gear 412 to rotate, thereby driving the gear 413 and the hollow shaft 35 to rotate. The inner wall of the mating groove 4131 is provided with a plurality of spaced bosses 4132, and the bottom of the hollow shaft 35 is provided with a plurality of spaced limiting grooves 351. The gear 413 is adapted to be fitted onto the hollow shaft 35 through the engagement of the bosses 4132 with the corresponding limiting grooves 351. Motor 411 drives worm gear 412 to rotate. Worm gear 412 transmits rotational motion to hollow shaft 35 through meshing with gear 413, thereby driving reflector assembly 1 to achieve precise adjustment of azimuth angle. The worm gear transmission mechanism itself has a large reduction ratio, which can effectively reduce speed and increase output torque, ensuring that the reflector has sufficient driving force and stability during rotation.

[0033] It should be noted that the specific structure of the first drive mechanism 41 is described with reference to the accompanying drawings. In actual use, it can also be set to other structures according to actual needs, as long as the above functions can be achieved. This is only for better illustrating the present invention and should not be construed as a limitation of the present invention.

[0034] In one embodiment, refer to the appendix to the specification. Figure 9 , Figure 10 The intelligent adjustable base station antenna also includes a locking mechanism 5. The locking mechanism 5 is located at the end of the reflector assembly 1 and is used to lock the reflector assembly 1 in its rotational position after it rotates to a set azimuth angle. The locking mechanism 5 can be located at the top of the reflector assembly 1. By setting the locking mechanism 5 at the end of the reflector assembly 1, when the drive assembly 4 rotates the reflector assembly 1 to the preset azimuth angle, the locking mechanism 5 will work to fix the reflector assembly 1 relative to its support structure, effectively avoiding unexpected angular deviations caused by factors such as wind load, vibration, or its own weight.

[0035] Reference manual attached Figure 11 The locking mechanism 5 includes a rotating component 51 and a locking component 52. The rotating component 51 includes a rotating shaft 511, which is rotatably mounted in the fixed bracket 31 of the rotating bracket 3 via a bushing 33. One end of the rotating shaft 511 is connected to the mounting plate 32. The locking component 52 is disposed between the rotating shaft 511 and the fixed bracket 31 to achieve relative locking or release between the two. The locking function of the rotating bracket 3 can be realized by the RET power unit, effectively reducing the shaking problem of the reflector assembly 1 and improving the azimuth angle maintenance and accuracy.

[0036] Reference manual attached Figure 12 , Figure 13 The locking assembly 52 includes a locking stop 521, a stop plate 522, a lever 523, a reset member 524, and a screw 527. The locking stop 521 is fixed to the end face of the fixed bracket 31. The stop plate 522 is axially movable on the rotating shaft 511. The lever 523 is drively connected to the stop plate 522. The reset member 524 is disposed on the guide shaft 525. The screw 527 is threadedly engaged with the lever 523. When the screw 527 rotates, it drives the lever 523 to move axially, thereby driving the stop plate 522 to engage or disengage from the locking stop 521. The rotating shaft 511 has a hole 5112. One end of the screw 527 passes through the hole 5112 and is rotatably connected to the hole 5112. The other end of the screw 527 has a power input end. The drive assembly 4 also includes a second drive mechanism 42, which is connected to the power input end and provides power input. When locking is required, the screw 527 rotates, causing the lever 523 to move axially. The lever 523 drives the stop plate 522 to overcome the elastic force of the reset member 524 and move away from the locking stop 521, thus unlocking. When locking is required, the screw 527 rotates in the opposite direction, the lever 523 moves in the opposite direction, and the reset member 524 uses its elastic restoring force to drive the stop plate 522 to move towards and engage with the locking stop 521, thus locking. This locking assembly 52 has a compact structure, short transmission chain, and rapid response, effectively meeting the reliability requirements of the locking mechanism 5 for base station antennas in complex outdoor environments.

[0037] Further, refer to the attached instruction manual. Figure 14 The rotating shaft 511 is provided with multiple axially extending guide posts 5111, and the stop plate 522 is provided with multiple corresponding guide holes 5221. The guide posts 5111 pass through the guide holes 5221 and are used to guide and limit the axial movement of the stop plate 522. The cooperation between the guide posts 5111 and the guide holes 5221 not only plays a guiding role, but also has a circumferential limiting function, effectively preventing unnecessary rotation of the stop plate 522 during movement and ensuring the alignment accuracy of the stop plate 522 when it engages with the locking stop 521.

[0038] Further, refer to the attached instruction manual. Figure 11 , Figure 15The locking stop 521 has a protrusion 5211 and the stop plate 522 has a groove 5222. When the protrusion 5211 and the groove 5222 are engaged, the locking mechanism 5 is in a locked state. When the protrusion 5211 and the groove 5222 are separated, the locking mechanism 5 is in a rotatable state. When the locking mechanism 5 is in a locked state, the protrusion 5211 on the locking stop 521 is embedded in the groove 5222 on the stop plate 522, forming a mechanical interlock and restricting the rotational freedom of the rotating shaft 511 relative to the fixed bracket 31. When azimuth angle adjustment is required, the protrusion 5211 and the groove 5222 are separated, and the rotating shaft 511 returns to a free rotational state.

[0039] Further, refer to the attached instruction manual. Figure 12 , Figure 13 The locking assembly 52 also includes a locking cover 526, a guide shaft 525, and a fixing plate 528. The locking cover 526 is fixedly connected to the stop plate 522. The guide shaft 525 is arranged axially to provide guidance for the axial movement of the paddle 523. The fixing plate 528 is disposed at the end of the screw 527 to connect to the second drive mechanism 42.

[0040] It should be noted that the specific structure of the locking component 52 is described with reference to the accompanying drawings. In actual use, it can also be set to other structures according to actual needs, as long as the above functions can be achieved. This is only for better illustrating the present invention and should not be construed as a limitation of the present invention.

[0041] The specific process of azimuth angle adjustment of the smart antenna provided in this embodiment is as follows: First, the second drive mechanism 42 drives the screw 527 to rotate, making the locking mechanism 5 rotatable. Then, the motor 411 of the first drive mechanism 41 drives the worm gear 412 to rotate, the worm gear 412 drives the gear 413 meshing with it to rotate, the gear 413 drives the hollow shaft 35 that is matched with it to rotate synchronously, and the hollow shaft 35 in turn drives the mounting plate 32 and the reflector assembly 1 fixedly connected to it to rotate, thereby realizing the automatic adjustment of the antenna azimuth angle.

[0042] When the reflector assembly 1 rotates to the preset angle, the second drive mechanism 42 drives the screw 527 to rotate in the opposite direction, so that the locking mechanism 5 switches from the rotatable state to the locked state, completing the locking of the azimuth angle and ensuring that the antenna maintains stable pointing accuracy during operation.

[0043] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0044] It should be noted that the above embodiments can be freely combined as needed. The above are merely optional embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
