Description

Technical Field

[0001] This invention relates to the field of integrated millimeter-wave transmission and multi-band coverage technology, specifically to an integrated system for millimeter-wave transmission and multi-band coverage. Background Technology

[0002] The integrated system of millimeter-wave transmission and multi-band coverage is the core technical architecture for achieving high-speed and wide-coverage collaborative communication, encompassing various equipment and collaborative technologies such as base stations, terminals, and core network scheduling units. The AAU (Active Antenna Unit) is the key hardware carrier in this integrated system, specifically responsible for the precise transmission and reception of millimeter-wave and mid-to-low-frequency signals. It has now evolved into a highly integrated device combining multi-band antennas, RF units, and signal processing modules. Its core design ensures signal coverage performance through a large-area antenna array, while improving communication efficiency through multi-module integration; therefore, it typically employs a thick rectangular panel design. The panel features regularly arranged antenna elements, densely packed with power amplifiers, ceramic dielectric filters, RF chips, and other components, and incorporates heat dissipation fins to handle heat generation. AAUs are commonly installed on communication towers or light poles, fixed by brackets to achieve high-altitude coverage, relying on the beamforming capabilities of the large-scale antenna array to ensure directional transmission and reception of millimeter-wave and multi-band signals.

[0003] In existing designs, the AAU is exposed to complex outdoor environments such as rain, snow, salt spray, sandstorms, ultraviolet radiation, and external impacts for extended periods. It is connected to light poles or communication towers via brackets, and the connection points are continuously subjected to tensile stress, which can easily lead to bracket fatigue, causing the AAU to shift at an angle or even fall off entirely. Furthermore, the splicing of the AAU shell and the radome often uses simple welding or screwing processes, and the sealing rings are prone to aging and failure under high and low temperature cycling environments, allowing moisture and salt spray to penetrate into the equipment and corrode the circuits and antenna elements.

[0004] In summary, the existing AAU structure is difficult to adapt to complex outdoor environments, which not only weakens the operational reliability of the AAU itself, but also directly affects the communication quality of the millimeter-wave multi-band integrated system, and leads to a significant increase in the outdoor operation and maintenance costs of the equipment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an integrated system for millimeter-wave transmission and multi-band coverage, enabling the AAU structure to adapt to complex outdoor environments, improving its operational reliability, and thus ensuring the communication quality of the integrated millimeter-wave multi-band system.

[0020] The technical solution of the present invention will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of the present invention should be understood as prior art known or should be known by those skilled in the art.

[0021] like Figures 1 to 3As shown, an integrated system for millimeter-wave transmission and multi-band coverage includes a mounting shell 2 for mounting an AAU and multiple fixing components 3 for fixing the mounting shell 2 to a rod 1. The mounting shell 2 includes an antenna radome 201 and a housing 202. The edge of the antenna radome 201 is provided with a first sealing platform 2011, and the edge of the housing 202 is provided with a second sealing platform 2021. The first sealing platform 2011 and the second sealing platform 2021 are connected, and the contact portions of the first sealing platform 2011 and the second sealing platform 2021 are fitted together. The antenna radome 201 is provided with multiple limiting grooves 2012, and the housing 202 is provided with multiple anti-detachment components 13 corresponding one-to-one with the limiting grooves 2012. The anti-detachment components 13 include components disposed on the housing 202. The connecting frame 1301 and lever 1302 are mounted on the rod. One end of the lever 1302 is rotatably connected to the connecting frame 1301, and the other end of the lever 1302 is provided with a protrusion 1303. During the rotation of the lever 1302, the protrusion 1303 can enter the limiting groove 2012. The fixing component 3 includes a retaining ring 301 and a steel wire 7. The retaining ring 301 is locked on the rod body 1. The retaining ring 301 is provided with a notch, and a mounting plate 305 connected to the housing 202 is provided at the notch. The end face of the retaining ring 301 is provided with multiple stress dispersion plates 303 and several through holes 304. The part of the stress dispersion plate 303 near the rod body 1 is in contact with the rod body 1. The steel wire 7 passes through at least one stress dispersion plate 303 and at least one through hole 304 and then wraps around the rod body 1.

[0022] AAU is a conventional prior art in this field, therefore Figure 2 Its specific structure is not shown in the figure.

[0023] The first sealing platform 2011 on the edge of the radome 201 and the second sealing platform 2021 on the edge of the housing 202 are mated together to form a labyrinth sealing structure, which improves the sealing performance of both. The first sealing platform 2011 and the second sealing platform 2021 are fixed together by connecting bolts 12. At the same time, an anti-detachment component 13 is added to the housing 202 to further avoid the risk of separation caused by wind, vibration and other factors in the outdoor environment.

[0024] One end of the lever 1302 of the anti-detachment component 13 is fixed to the housing 202 via the connecting bracket 1301, and the other end is engaged in the limiting groove 2012 via the protrusion 1303. When the radome 201 shows a tendency to loosen and fall off due to long-term vibration or external impact, the protrusion 1303 in the limiting groove 2012 forms a rigid block, limiting the displacement of the radome 201 to reduce the risk of falling off. When it is necessary to maintain the internal structure of the radome 201, the lever 1302 is rotated in the opposite direction to disengage the protrusion 1303 from the limiting groove 2012.

[0025] The connecting frame 1301 and the lever 1302 are made of 304 stainless steel, and the surfaces of the connecting frame 1301 and the lever 1302 are galvanized to improve their corrosion resistance.

[0026] like Figure 1 and Figure 4 As shown, the position of the retaining ring 301 is adjusted according to the installation height, and the retaining ring 301 is secured to the rod body 1 through its notch. The notch of the retaining ring 301 forms two end faces, and two mounting plates 305 are correspondingly set and fixedly connected. The mounting plates 305 are then tightened with bolts to fix the position of the retaining ring 301 and the rod body 1. Multiple stress-dispersing plates 303 are provided on the end face of the retaining ring 301, which are in contact with the surface of the rod body 1 to disperse the stress between them; at the same time, through holes 304 are opened on the end face to facilitate rainwater drainage. Figure 1 As shown, to further enhance the stability of the housing 202, a steel wire 7 is wound around the rod 1. The steel wire 7 passes through the stress dispersion plate 303 and the through hole 304 in sequence, and then its two ends are wrapped around the rod 1 and tied tightly to the body of the steel wire 7 to prevent it from falling off. The surface of the steel wire 7 is galvanized to improve its corrosion resistance.

[0027] The present invention uses a fixing component 3 to fix the mounting shell 2, an anti-detachment component 13 to prevent the antenna cover 201 from falling off, and a steel wire 7 for pre-tightening reinforcement, so that the AAU structure can adapt to complex outdoor environments, improve its own operational reliability, and thus ensure the communication quality of the millimeter wave multi-band integrated system.

[0028] To further enhance the sealing effect between the radome 201 and the housing 202, the first sealing platform 2011 is configured in a first stepped shape, and the second sealing platform 2021 is configured in a second stepped shape to cooperate with the first sealing platform 2011. The interlocking concave and convex structures increase the sealing contact area of ​​the first and second sealing platforms 2011 and 2021. This stepped fit not only effectively disperses assembly pressure and stress during use, preventing localized sealing failure, but also forms multiple sealing barriers to block the penetration of moisture, dust, and other impurities. Both the stepped surfaces of the first and second sealing platforms 2011 and 2021 are provided with grooves, and a sealing and wear-resistant rubber layer is installed within these grooves.

[0029] The connecting bracket 1301 is L-shaped, with one end connected to the housing 202 and the other end rotatably connected to the lever 1302 via a rotating shaft. To prevent the protrusion 1303 near the lower part of the housing 202 from falling out of the limiting groove 2012 due to gravity, the limiting groove 2012 is provided with an extension area. The protrusion 1303 on the lever 1302 is provided with an elastic protrusion 1304 that presses into the extension area. When the lever 1302 rotates around the rotating shaft, the protrusion 1303 moves synchronously with the lever 1302. When the elastic protrusion 1304 contacts the edge of the limiting groove 2012, it undergoes elastic deformation and is smoothly pressed into the extension area, forming a secondary limiting lock. The part of the protrusion 1303 that enters the limiting groove 2012 is designed as an arc surface.

[0030] The retaining ring 301 includes two annular bodies distributed vertically, connected by multiple first bolts 302. The through holes 304 on the two annular bodies correspond one-to-one. Notches and stress-dispersing plates 303 are both provided on the annular bodies. The notches on the two annular bodies are aligned to form an installation space for mounting plates 305. The aligned notches on the two annular bodies together form the installation space, and the two mounting plates 305 are fixed within this space.

[0031] like Figure 5 As shown, the housing 202 is provided with connecting plates 4 and liners 11 corresponding to the mounting plates 305. The connecting plates 4 include a first part 401 and a second part 402. The first part 401 is connected to the housing 202, and the second part 402 is connected to the mounting plates 305. The mounting plates 305 and the liners 11 are connected by an adjusting assembly 6. The adjusting assembly 6 includes an internally threaded sleeve 601, a first screw 602 and a second screw 603. The threads of the first screw 602 and the second screw 603 are opposite in direction. The first screw 602 is rotatably connected to the liners 11, and the second screw 603 is rotatably connected to the mounting plates 305.

[0032] To enhance connection stability, two mounting plates 305 are provided, and therefore, two connecting plates 4 are also provided accordingly. There is a gap between the two mounting plates 305 and the two connecting plates 4. During connection, following the distribution pattern of one mounting plate 305, one connecting plate 4, the other mounting plate 305, and the other connecting plate 4, adjacent mounting plates 305 and connecting plates 4 are fitted together and connected by the second bolt 5.

[0033] To further enhance the stability of the connection between the housing 202 and the retaining ring 301, the first screw 602 is rotatably connected to the liner 11 via a rotating joint, and the second screw 603 is rotatably connected to the mounting plate 305 via a rotating joint. After the retaining ring 301 and the housing 202 are installed, the internal threaded sleeve 601 is rotated according to the distance between the housing 202 and the rod 1, so that the distance between the first screw 602 and the second screw 603 moves closer or further apart, thereby ensuring the stability of the connection between the housing 202 and the retaining ring 301. Even if the connection between the mounting plate 305 and the connecting plate 4 becomes loose or even fails, causing the housing 202 to be at risk of falling off, the adjusting component 6 can still function. At this time, the meshing and locking structure of the first screw 602, the second screw 603, and the internal threaded sleeve 601 will still prevent the housing 202 from falling off directly.

[0034] To further enhance the performance of the steel wire 7 and prevent the housing 202 and the retaining ring 301 from detaching, the portion of the steel wire 7 passing through the stress dispersion plate 303 and the through hole 304 is bent into two bends, with both ends of the steel wire 7 corresponding to the bends. The bends formed by the bending of the steel wire 7 prevent the steel wire 7 from shifting in a vibrating environment, ensuring the stability of the connection position; furthermore, when the housing 202 and the retaining ring 301 show a tendency to separate, the steel wire 7 can quickly form a reverse constraint, thereby preventing the separation tendency from further expanding.

[0035] One of the bends is connected to the connecting plate 4 via a spring 8. When the housing 202 and the retaining ring 301 are stably installed, the spring 8 is in an initially relaxed state; if the connection of the housing 202 fails and causes it to fall off, the spring 8 will gradually stretch as the housing 202 is displaced, buffering the falling speed of the housing 202 through elastic deformation, reducing the impact force between the housing 202 and other components, and reducing the risk of damage to the housing 202.

[0036] The top of the housing 202 is provided with an arc-shaped protective cover 9, which extends toward the retaining ring 301. The protective cover 9 is arc-shaped, and a baffle 10 is provided at the edge of the protective cover 9. The protective cover 9 can shield the connecting plate 4, the liner 11, the adjusting assembly 6, and the mounting plate 305, preventing these components from being corroded by rainwater and snow. The baffle 10 can guide rainwater and snow falling on the protective cover 9 to slide off along the arc-shaped protective cover 9, while reducing water seepage into the shielded components.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
