Description

Technical Field

[0001] The present invention relates to the technical field of 5G base station antennas, and in particular to a base station antenna with a 5G network radio frequency antenna. Background Art

[0002] The antenna setting of 5G base station needs to focus on parameters such as downtilt angle, azimuth angle, antenna hanging height, antenna diversity distance and isolation distance. Reasonable setting of antenna downtilt angle can not only reduce the impact of co-channel interference, effectively control the coverage range of base stations and the soft switching ratio of the entire network, but also enhance the signal strength within the coverage area of ​​this base station. Usually, the setting of antenna downtilt angle has two focuses, namely, focusing on interference suppression and focusing on strengthening coverage. Generally speaking, areas with dense distribution of base stations should focus on interference suppression, while areas with sparse distribution of base stations should focus on strengthening coverage. In actual application, due to the complex environment around the base station, the downtilt angle setting of the antenna must also consider the reflection and obstruction of nearby mountains, water surfaces and tall glass curtain walls. Therefore, the downtilt angle of a specific base station can be determined by the above method and combined with the specific environment.

[0003] The existing Chinese patent application with publication number CN113178682A discloses a base station antenna and base station radio frequency equipment for a 5G network, aiming to solve the problem of how to conveniently and quickly adjust the downtilt angle and azimuth angle of the base station antenna, including a standard section, a first platform, a first connecting column, a second platform, an antenna device, a lightning protection device and a rotating device. The standard section includes a first support, a second support, a first connecting rod, a second connecting rod, a first mounting plate, a first bolt, a first ladder, a second mounting plate and a second bolt. The first platform includes a first side panel, a third mounting plate, a first bracket, a first fixed net and a second ladder. The second platform includes a second bracket, a second fixed net and a guardrail. Through the setting of the rotating device and the antenna device, the inclination angle and position of the antenna device can be adjusted conveniently and quickly, avoiding the staff from repeatedly going to the antenna device for manual adjustment, which is extremely time-consuming and solves the problem of low work efficiency.

[0004] However, since the above solution can only adjust the downtilt angle of the base station antenna, the rotation azimuth angle cannot be adjusted and the adjustment angle is not quantified, it is not convenient for later remote intelligent remote control adjustment. In addition, since the position angle of the antenna unit changes, the protective cover that originally played a protective function may have a blind spot, thereby posing a risk of equipment damage in hail weather. At the same time, in rainy and snowy weather, the accumulated rain and snow may penetrate into the base station antenna after melting and refreeze, making the rotation angle and downtilt angle adjustment functions unavailable, and manual cleaning is time-consuming and labor-intensive.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, provides a base station antenna with a 5G network radio frequency antenna, including a frame 100, an antenna unit 101, a radio frequency unit and an angle adjustment mechanism. The rotation angle of the antenna unit 101 is accurately controlled by the rotating shaft 1002, and the angle adjustment is quantified as the number of rotations. At the same time, the downtilt angle adjustment is controlled by the moving distance of the rotating member 301, and the angle of the downtilt angle is also quantified.

[0038] Specifically, it includes: a frame 100, on which a circumferential array of antenna units 101 are arranged, and the antenna units 101 are used to send and receive wireless signals;

[0039] A radio frequency unit, which is mounted on the frame 100 and close to the antenna unit 101, and is used to convert a baseband signal into a radio frequency signal and perform signal amplification and filtering operations;

[0040] The angle adjustment mechanism includes an antenna shield 300 disposed on the antenna unit 101 and a rotating member 301 disposed in the frame 100. The rotating member 301 drives the antenna unit 101 and the antenna shield 300 to adjust their angles when rotating in clockwise and counterclockwise directions.

[0041] Among them, the base station antenna with a 5G network radio frequency antenna in the present invention is a circular array distribution of eight antenna units 101, so as to realize the transmission and reception of radio signals in all directions. The frame 100 is a hollow cylinder, and the antenna cover 300 is arranged directly above the antenna unit 101 and is fan-shaped. After each antenna cover 300 is spliced ​​together at the front and back, a complete cone is formed.

[0042] Preferably, a tower base 1001 is fixedly provided below the frame 100 , a rotating shaft 1002 is rotatably provided on the outer wall of the frame 100 , the lower end of the antenna unit 101 is rotatably connected to the rotating shaft 1002 , and a buffer connecting plate 1003 is rotatably provided on the upper end of the antenna unit 101 .

[0043] More preferably, a cavity 1004 is opened in the frame 100 , a transmission wheel 1005 is provided on the outer wall of the rotating shaft 1002 that rotates and penetrates into the cavity 1004 , a first transmission bar 1006 is provided on the end surface of the buffer connecting plate 1003 , and a second transmission bar 1007 is also provided in the cavity 1004 .

[0044] The first transmission bar 1006 and the second transmission bar 1007 are arranged in parallel and both are meshed with the transmission wheel 1005 at the same time.

[0045] Illustratively, in this embodiment, the transmission wheel 1005 is rotatably mounted on the outer wall of the rotating shaft 1002 and does not move synchronously therewith, thereby realizing separate adjustments to the flip angle and the rotation angle of the antenna unit 101. In other embodiments, the transmission wheel 1005 can be fixedly connected to the rotating shaft 1002 and remain relatively stationary, so that when the rotating shaft 1002 rotates, the antenna unit 101 can be adjusted vertically and flipped horizontally at the same time, thereby realizing synchronous adjustment of the two.

[0046] More preferably, the lower end of the antenna unit 101 is fixedly connected to the rotating shaft 1002 and rotates synchronously therewith, the buffer connecting plate 1003 is made of hard plastic, and the rotation direction of the buffer connecting plate 1003 is: turning outward or inward with the lower end of the buffer connecting plate 1003 as the center.

[0047] More preferably, the transmission wheel 1005 is a gear, and the first transmission bar 1006 and the second transmission bar 1007 are racks, so that the antenna unit 101 is flipped by the telescopic movement of the second transmission bar 1007. In this embodiment, the rotating member 301 is a transmission shaft and is driven by a servo motor.

[0048] Furthermore, a bracket 1008 is sleeved on the outer wall of the rotating shaft 1002, the rotating member 301 rotates through the bracket 1008 and is vertically provided with a pointer arm 1009, and a dial 1014 is also provided on the outer wall of the rotating shaft 1002. A lower connecting rod 1015 is provided on the lower outer wall of the dial 1014, and the lower connecting rod 1015 is fixedly connected to the second transmission bar 1007.

[0049] More preferably, a swing frame 1011 is fixedly provided on the outer wall of the rotating shaft 1002 , a sliding sleeve 1012 is movably sleeved on the outer wall of one side of the swing frame 1011 , a sliding rod 1013 is fixedly provided on the outer wall of the sliding sleeve 1012 , and the sliding rod 1013 movably penetrates the pointer arm 1009 .

[0050] Among them, the bracket 1008 is in the shape of a gate, the rotating member 301 rotates through the symmetrical center line position of the bracket 1008 and can slide relatively therewith, the swing frame 1011 is also in the shape of a gate, the center line position of the swing frame 1011 is a cylinder, the sliding sleeve 1012 is a cylindrical ring and the sliding sleeve is arranged on its outer wall to slide up and down and rotate.

[0051] More preferably, the dial 1014 is provided with scale lines, and reference Figure 5 The clock area is divided according to the position of the dial 1014, and the rotation angle of the pointer arm 1009 on the dial 1014 is recorded by a position sensor. The pointer arm 1009 is arranged parallel to the dial 1014, and the lower connecting rod 1015 slides through the bracket 1008 and can slide inside it to drive the second transmission bar 1007 to move.

[0052] In summary, in the present embodiment, when the rotating member 301 is driven to rotate by the servo motor, the pointer arm 1009 is driven to rotate, so that the slide bar 1013 slidingly arranged on the pointer arm 1009 follows the rotation of the pointer arm 1009. When the pointer arm 1009 rotates clockwise from the 9 o'clock direction on the initial dial 1014 to the 3 o'clock direction, the slide bar 1013 and the swing frame 1011 are driven to swing clockwise, so that the rotating shaft 1002 drives the antenna unit 101 to swing clockwise by a corresponding angle. Conversely, when the pointer arm 1009 moves counterclockwise from the 3 o'clock direction to the 9 o'clock direction, the rotating shaft 1002 drives the antenna unit 101 to swing counterclockwise by a corresponding angle, so that the rotation angle and position of the pointer arm 1009 are controlled according to the number of rotations of the rotating member 301, thereby controlling the rotation angle of the antenna unit 101.

[0053] At the same time, when considering strengthening coverage in areas where base stations are sparsely distributed or strengthening interference function in areas where base stations are more distributed, it is necessary to adjust the downtilt angle of the antenna unit 101. At this time, the servo motor and the rotating part 301 are controlled by the cylinder to slide along the axis direction of the rotating part 301 as a whole, thereby driving the dial 1014 to move, and driving the second transmission bar 1007 to move through the lower connecting rod 1015. When the second transmission bar 1007 moves, the transmission wheel 1005 makes the first transmission bar 1006 move a corresponding distance, so that the buffer connecting plate 1003 drives the upper end of the antenna unit 101 to move forward or backward, thereby realizing the adjustment of the downtilt angle of each antenna unit 101.

[0054] Example 2

[0055] Reference Figure 1 to Figure 8 , which is the second embodiment of the present invention, is based on the previous embodiment, except that the rotating member 301 can adjust the downtilt angle of the antenna unit 101 or the rotation angle of the antenna unit 101 when rotating forward and reversely, so as to adapt to the requirements of base station antenna array arrangement in different scenarios.

[0056] Specifically, a pull ring 2001 is fixedly provided on the end surface of the scale plate 1014, a shell 2002 is provided on the frame 100, a switching sleeve 2003 is coaxially rotatably provided inside the shell 2002, and the pull ring 2001 and the switching sleeve 2003 are rotatably fitted together.

[0057] The switching sleeve 2003 is in the shape of a hollow cylinder, and the rotating member 301 is coaxially arranged on the inner wall of the switching sleeve 2003 , and the pull ring 2001 is slidably sleeved on the outer wall of the switching sleeve 2003 .

[0058] Furthermore, a thread groove 2004 is provided on the outer wall of the switching sleeve 2003 , and a sliding column 2005 is radially provided on the inner wall of the pull ring 2001 , and the sliding column 2005 is slidably disposed on the inner wall of the thread groove 2004 .

[0059] More preferably, there are three sliding posts 2005 arranged in a linear array along the axis of the switching sleeve 2003 at intervals of the length of the switching sleeve 2003, and the thread groove 2004 is a spiral groove penetrating on both sides, the spiral line has a total of one circle, and the rotation angle is 360°.

[0060] The starting point and the end point of the thread groove 2004 on the switching sleeve 2003 are on the same side line, so that after the previous sliding post 2005 slips off the thread groove 2004, the next sliding post 2005 just enters the thread groove 2004 from the starting point.

[0061] More preferably, a driving rod 2006 is also passed through the axis of the switching sleeve 2003 , a first sliding groove and a first rotating groove 2008 are formed on the end surface of the rotating member 301 , and a second sliding groove and a second rotating groove 2011 are formed on the switching sleeve 2003 near the driving rod 2006 .

[0062] Among them, the driving rod 2006 slides through the end of the rotating member 301 and is provided with a first block 2012, and the driving rod 2006 slides to the end of the switching sleeve 2003 and is provided with a second block 2013.

[0063] Furthermore, the first slide groove is arranged perpendicularly to the first rotating groove 2008, and the second slide groove and the second rotating groove 2011 are also arranged perpendicularly. Both slide grooves are waist-shaped slide grooves and are arranged along the axial direction of the driving rod 2006. The first rotating groove 2008 and the second rotating groove 2011 are circular grooves and are arranged perpendicularly to the axial direction of the driving rod 2006.

[0064] The first clamping block 2012 and the second clamping block 2013 are waist-shaped sliders, so they can slide in the two slide grooves along the axis direction of the driving rod 2006, and can also rotate in the two rotating grooves.

[0065] Illustratively, in this embodiment, when the first block 2012 rotates in the first rotating groove 2008, the second block 2013 is located on the inner wall of the second sliding groove; when the second block 2013 rotates in the second rotating groove 2011, the first block 2012 is located on the inner wall of the first sliding groove.

[0066] More preferably, the driving rod 2006 is driven by the oil cylinder to move forward and backward to realize the movement of the positions of the first block 2012 and the second block 2013. The driving rod 2006 is controlled by a servo motor and can rotate forward or reverse.

[0067] Furthermore, the base station antenna with a 5G network radio frequency antenna also includes a control module, which is applied to the antenna base station and is used to determine the movement mode and control the antenna unit 101 to move to a set position. The control module includes an adjustment logic, and the adjustment logic includes:

[0068] S1: Obtain the horizontal rotation angle and inclination angle of the current antenna unit 101;

[0069] S2: Obtain the current area environment information and determine whether to enhance the interference function or the coverage function;

[0070] S3; obtain the distribution of 5G network base station antennas in the area and calculate the adjusted horizontal rotation angle and inclination angle;

[0071] S4: Calculate the number of rotations of the driving rod 2006 and the rotating member 301 according to the horizontal rotation angle and the front and rear difference of the inclination angle, and adjust the angles of the antenna unit 101 and the antenna cover 300.

[0072] Through the above adjustment logic, after adding a base station antenna, the antenna unit 101 and the radio frequency unit can be adaptively adjusted in angle according to the base station distribution to avoid mutual interference and achieve the best working mode.

[0073] In summary, when in use, when it is necessary to adjust the downward tilt angle of the antenna unit 101, push the drive rod 2006 to move until the first block 2012 is in the first rotating groove 2008, so that when the drive rod 2006 rotates, it does not drive the rotating member 301 to rotate. At the same time, the second block 2013 is on the inner wall of the second slide groove, and the second block 2013 drives the second slide groove and the switching sleeve 2003 to rotate, so that the slide column 2005 rotates along the threaded groove 2004. Since the pull ring 2001 can only move but not rotate, the rotation of the switching sleeve 2003 drives the pull ring 2001 and the dial 1014 to move, thereby realizing the adjustment of the downward tilt angle of the antenna unit 101, and the drive rod 2006 rotates in the positive and negative directions to control the angle deflection direction.

[0074] At the same time, when it is necessary to adjust the signal transmission angle according to the distribution of the antenna units 101 of the array, it is necessary to rotate the angle of the antenna unit 101. At this time, the driving rod 2006 is moved in the opposite direction. When the second block 2013 rotates in the second rotating groove 2011, the first block 2012 is on the inner wall of the first sliding groove. When the driving rod 2006 rotates, it drives the rotating member 301 to rotate without affecting the switching sleeve 2003, thereby realizing a separate horizontal angle rotation. Fine-tuning is performed by rotating the driving rod 2006, and the angle parameters are recorded in real time to facilitate later reproduction, thereby expanding the product application scenarios.

[0075] Example 3

[0076] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the dial 1014 no longer moves synchronously with the rotating member 301. Instead, when the rotating member 301 rotates, it drives the dial 1014 to move at the same frequency. At the same time, the antenna cover 300 always moves synchronously with the antenna unit 101 and provides protection, eliminating the protection blind area formed after the angle adjustment, and reducing the damage to the base station antenna in environments such as hail, rain, snow and ice.

[0077] Specifically, a ball 3001 is provided at one end of the slide rod 1013 that slides through to the outside of the pointer arm 1009, and a dial 1014 is movably arranged in the outer area of ​​the rotating member 301 without being in contact with it. A sliding groove 3002 is provided on the outer wall of the dial 1014, and steps 3003 are provided in a circular array within the sliding groove 3002.

[0078] Among them, the sliding groove 3002 is circular, and the ball 3001 is rolled and sleeved on the end of the sliding rod 1013. In the initial state, the ball 3001 does not contact the dial 1014. The movement amplitude when adjusting the antenna unit 101 also makes the dial 1014 not contact the ball 3001.

[0079] More preferably, when the dial 1014 approaches the slide bar 1013, the ball 3001 rolls on the inner wall of the slide groove 3002 and along the step 3003 in the slide groove 3002, thereby driving the antenna unit 101 to swing back and forth through the lower connecting rod 1015, and throwing out the snow and ice accumulated on the surface of the antenna unit 101 to prevent it from affecting signal transmission and freezing inside the antenna unit 101 after melting.

[0080] Furthermore, an upper connecting rod 3004 is provided on the upper end surface of the dial 1014 . The upper connecting rod 3004 passes through the bracket 1008 and is provided with a ball 3005 . The ball 3005 always rolls against the inner wall of the antenna shield 300 .

[0081] The outer shell of the antenna shield 300 is made of plastic, and the inner wall of the antenna shield 300 is covered with a metal sheet to enhance the strength of the antenna shield 300. The ball 3005 is magnetic, so it always fits the inner wall of the antenna shield 300.

[0082] More preferably, the rotating shaft 1002 passes through one end of the bracket 1008 and is provided with a swing knot 3006 . The inner wall of the antenna shield 300 is also provided with a protrusion 3007 , and the protrusion 3007 is rotatably arranged in the swing knot 3006 .

[0083] Among them, the protrusion 3007 is vertically fixed on the inner wall of the antenna shield 300. In the initial state, the antenna shield 300 swings with the swing knot 3006 as the center of the circle, and is always limited and adsorbed by the ball 3005.

[0084] More preferably, if Figure 3 As shown, the antenna shield 300 is set at an overall tilted angle. When the ball 3005 approaches the swing knot 3006, it pushes the antenna shield 300 to rotate counterclockwise. The shielding range below the antenna shield 300 is reduced and the slope is increased, which facilitates the rolling of rain, snow and hail and reduces accumulation.

[0085] Preferably, when the ball 3005 is away from the swing knot 3006, the antenna shield 300 rotates clockwise to provide a larger protection range for the antenna unit 101. When the upper connecting rod 3004 drives the ball 3005 to move back and forth in a frequency cycle, the antenna shield 300 is vibrated to shake off the accumulated snow and rainwater, preventing it from melting and penetrating and then refreezing to affect the normal operation of the equipment, so that there is no need to remove ice and snow in small-scale rain and snow.

[0086] In summary, when in use, as the rotating shaft 1002 rotates to adjust the angle of the antenna unit 101, the antenna shield 300 also rotates synchronously with the swing knot 3006 through the protrusion 3007, so as to always protect the antenna unit 101 and avoid the generation of a protection blind spot after the angle adjustment, thereby avoiding damage by severe weather such as hail. At the same time, when the dial 1014 moves to change the downward inclination angle of the antenna unit 101, the upper connecting rod 3004 drives the inclination angle of the antenna shield 300 to change synchronously through the movement of the ball 3005, so as to always protect the antenna unit 101.

[0087] At the same time, when encountering rainy and snowy weather, snow and rainwater remain on the surface of the antenna shield 300 and the antenna unit 101. After melting, the surface is covered with ice again, which requires manual de-icing, which is time-consuming and laborious. At this time, the first block 2012 on the driving rod 2006 is moved into the first slide groove and the rotation is started. As the antenna shield 300 rotates upward, the rain and snow accumulation on the left side of the swing knot 3006 causes the weight to increase. Due to the lever principle, the right side of the antenna shield 300 rises, thereby driving the ball 3005 to roll inward, and driving the dial 1014 to move toward the sphere 3001 through the upper connecting rod 3004. The sphere 3001 moves and rolls along the step 3003 in the sliding groove 3002. At the same time, as the pointer arm 1009 rotates, the sphere 3001 rolls and rises and falls cyclically, thereby driving the antenna unit 101 to swing back and forth through the lower connecting rod 1015, and throwing out the snow and ice accumulated on the surface of the antenna unit 101 to prevent it from affecting signal transmission and melting and freezing inside the antenna unit 101. At the same time, the antenna shield 300 connected to the upper connecting rod 3004 reduces the inclination angle and reciprocates, causing the residual snow and rainwater to fall, thereby reducing the surface ice on the base station antenna.
