Description

Technical Field

[0001] The present invention relates to the technical field of base station antenna equipment, and in particular to a two-dimensional adjustable antenna installation device. Background Art

[0002] In the field of mobile communications, it's often necessary to adjust the mounting bracket to position the base station antenna at specific horizontal and vertical angles to achieve maximum signal coverage for the application scenario. Conventional mounting brackets often only allow vertical angle adjustment through the bracket's telescopic mechanism, but not horizontal adjustment. Furthermore, due to the limited structure of the telescopic mechanism, the achievable vertical angle adjustment range is often limited. Consequently, conventional mounting brackets cannot meet the practical needs of many application scenarios.

[0003] Although the patent titled “A multi-scenario antenna installation device with two-dimensionally adjustable mechanical tilt angle” and publication number (CN105390813) provides an installation device with two-dimensionally adjustable mechanical tilt angle that can simultaneously meet the horizontal and vertical angle adjustment requirements of the base station antenna, the installation device still has the following obvious deficiencies: First, the main body of the first adjustment plate is an “L”-shaped structure. Although some reinforcing ribs connect the two sides of the “L” shape, the overall structural strength of the first adjustment plate is still relatively poor, and deformation may occur under extreme working conditions, leading to the risk of being unable to adjust the horizontal angle. Secondly, the cantilever structure of the second adjustment plate is relatively long, and its cantilever structure is only fastened to the mounting plate by a single bolt, so its angle stability is relatively poor. In summary, the overall structural strength of the installation device is relatively low, and its stability is poor, making it unsuitable for use with antennas with a large windward area under extreme working conditions.

[0004] In view of this, there is an urgent need to develop a new base station antenna mounting bracket that can achieve two-dimensional large-angle adjustment while having the characteristics of high structural strength, light weight, simple and quick installation and adjustment process, and is applicable to many scenarios.

[0035] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0036] Please refer to the attached Figure 1 -Attached Figure 6 ,like Figure 1 As shown, an embodiment of the present invention provides a two-dimensionally adjustable antenna mounting device. The two-dimensionally adjustable antenna mounting device includes a horizontal angle adjustment device for adjusting the horizontal angle of the antenna 5, a vertical angle adjustment device for adjusting the vertical angle of the antenna 5, and a clamping device. The horizontal angle adjustment device includes a first adjustment plate 10, a fastening assembly, and a fastening bolt 13.

[0037] The horizontal angle adjustment device includes a first adjustment plate 10 which is fixedly connected to the antenna 5 and has an arc-shaped plate structure.

[0038] The vertical angle adjustment device includes a second adjustment plate 11, which includes an arc-shaped main plate. The inner arc surface of the main plate and the outer arc surface of the first adjustment plate 10 are fitted together and connected by a fastening assembly. The first adjustment plate 10 and the second adjustment plate 11 can rotate relative to each other in the horizontal direction, thereby realizing the adjustment of the horizontal angle of the antenna 5.

[0039] The fastening assembly includes an outer clamping plate 121 located on one side of the outer arc surface of the main body plate and in the shape of a rectangular parallelepiped, an inner clamping plate 120 located on one side of the inner arc surface of the first adjustment plate 10 and with a U-shaped cross-section, and a fastening bolt 13. The first adjustment plate 10 is provided with an arc-shaped slide groove 101 that passes through the first adjustment plate 10, and the second adjustment plate 11 is provided with a second mounting hole 115. The inner clamping plate 120 is provided with a fourth mounting hole 1200, and the outer clamping plate 121 is provided with a threaded hole 1210. The fastening bolt 13 passes through the fourth mounting hole 1200, the arc-shaped slide groove 101, and the second mounting hole 115 in sequence and is connected to the threaded hole 1210.

[0040] The side of the outer clamping plate 121 close to the second adjustment plate 11 is set as an inner concave arc surface, which is in contact with the outer arc surface of the main plate. The horizontal plane projection shape of the side of the inner clamping plate 120 close to the first adjustment plate 10 is an arc shape that can be tightly attached to the inner arc surface of the first adjustment plate 10.

[0041] Combine Figure 2 and Figure 3 As shown, in this embodiment, by providing a fastening assembly and a fastening bolt 13, the first adjustment plate 10 and the second adjustment plate 11 can be connected into one body, and the first adjustment plate 10 and the second adjustment plate 11 can rotate relative to each other in the horizontal direction, thereby realizing the adjustment of the horizontal angle of the base station antenna 5.

[0042] Preferably, the first adjustment plate 10 is semicircular, with the center of the arc located within the mounting surface of the first adjustment plate 10. Tests have shown that the curved first adjustment plate 10 has a stronger load-bearing capacity and is lighter than a conventional "L"-shaped adjustment plate under the same load. Therefore, a two-dimensionally adjustable mounting device using the curved first adjustment plate 10 improves structural strength while also reducing its size.

[0043] Specifically, the arcuate slot 101 is built into the center surface of the first adjustment plate 10, which is a curved plate-like structure, and extends through both sides of the curved wall surface of the first adjustment plate 10. The arcuate slot 101 is used to pass the fastening bolts 13 to achieve horizontal rotation of the first adjustment plate 10 relative to the main body of the second adjustment plate 11. The arc length of the arcuate slot 101 is such that the horizontal angular deviation between the first adjustment plate 10 and the main body of the second adjustment plate 11 is ≥±60°.

[0044] In this embodiment, at least one of the upper and lower ends of the outer arc surface of the first adjustment plate 10 has a horizontal angle mark 102 evenly distributed along the arc surface, and at least one of the upper and lower side walls of the main plate is provided with a V-shaped notch 116 for cooperating with the horizontal angle mark 102 on the first adjustment plate 10 to display the inclination angle of the horizontal angle adjustment of the antenna 5.

[0045] A reinforcing wall 100 is respectively provided on the upper and lower arc edges of the outer arc surface of the first adjustment plate 10, and a mounting wall 103 is respectively provided on the two end surfaces in the length direction of the first adjustment plate 10. The mounting wall 103 is provided with a first mounting hole 104 for connecting with the mounting plate on the antenna 5 with a bolt.

[0046] Specifically, the reinforcing wall 100 is attached to both sides of the upper and lower curved edges of the outer curved surface of the first adjustment plate 10, parallel to the horizontal plane and away from the center of the curved plate-like structure. The reinforcing wall 100 further increases the structural strength of the first adjustment plate 10 along the x, y, and z axes, allowing it to withstand greater additional loads without deformation, thereby ensuring smooth horizontal angle adjustment and connection reliability. The reinforcing wall 100 forms a 90° angle with the first adjustment plate 10 on a normal cross-sectional plane passing through the center of the first adjustment plate 10, thereby maximizing the bending resistance of the first adjustment plate 10.

[0047] The present invention provides horizontal angle markings 102 evenly distributed along the arc surface at the upper and lower ends of the outer arc surface of the first adjustment plate 10, which, in conjunction with the V-shaped notch 116 on the main plate of the second adjustment plate 11, can facilitate the operator to accurately adjust the horizontal angle of the device from various angles during operation.

[0048] Specifically, the V-shaped notch 116 is provided at the center position of both side walls of the width of the arc-shaped main plate of the second adjustment plate 11 .

[0049] Specifically, there are two first mounting holes 104 on each mounting wall 103, and the spacing between the two first mounting holes 104 is consistent with the spacing between the positioning holes on the mounting plate outside the antenna 5, so that the mounting plate outside the antenna 5 can be connected to the first adjustment plate 10 as a whole by bolts, thereby allowing the antenna 5 to move synchronously with the first adjustment plate 10 as a whole.

[0050] The inner clamping plate 120 includes a third base body of a planar structure and a group of supporting walls 1201 connected to and opposite to the third base body.

[0051] There are two fourth mounting holes 1200 on the third base, which are symmetrically arranged with respect to the center plane in the length direction of the third base. The spacing between the two fourth mounting holes 1200 is the same as the spacing between the two threaded holes 1210 on the outer clamping plate 121 and the spacing between the two second mounting holes 115 on the main body plate.

[0052] The horizontal projection of the support wall 1201 is an arc of equal radius that can completely abut against the inner arc surface of the first adjustment plate 10, thereby creating a larger contact area between the two and generating greater frictional resistance to enhance the horizontal load-bearing capacity of the device. The wall thickness of the inner clamping plate 120 is generally the same as that of the first adjustment plate 10.

[0053] The inner concave arc surface of the outer clamping plate 121 and the inner arc of the main plate of the second adjustment plate 11 have the same radius, so the arc surfaces therebetween can be completely in contact with each other, so that there is a larger contact area therebetween.

[0054] The planar end surface of the outer plate 121 has two threaded holes 1210 symmetrically arranged about the longitudinal center plane of the outer plate 121 and extending through the thickness of the outer plate 121. The thickness of the outer plate 121 is such that the threaded holes 1210 have sufficient thread depth to form an effective threaded connection with the fastening bolt 13.

[0055] Preferably, a relief groove 1211 is provided at each end of the outer plate 121 in the longitudinal direction, symmetrically arranged about the longitudinal center plane of the outer plate 121. The relief groove 1211 completely penetrates the thickness direction of the outer plate 121. The length of the relief groove 1211 should be slightly larger than the opposite-side dimension of the bolt head of the first adjusting bolt 22, and the width of the relief groove 1211 should be larger than the thickness of the bolt head of the first adjusting bolt 22. This allows the bolt head of the first adjusting bolt 22 to slide within the relief groove 1211 without relative rotation, facilitating tightening or loosening operations of the first adjusting bolt 22.

[0056] When installing the horizontal angle adjustment device, the fastening bolt 13 is passed through the fourth mounting hole 1200 on the inner clamping plate 120, the arc-shaped slide groove 101 on the first adjustment plate 10, the second mounting hole 115 on the main plate of the second adjustment plate 11, and the threaded hole 1210 on the outer clamping plate 121 in sequence, thereby connecting the horizontal angle adjustment device into one.

[0057] Combine Figure 6As shown, when the horizontal angle of the antenna 5 needs to be adjusted, the fastening bolts 13 on the inner clamping plate 120 are loosened, and the antenna 5 connected to the first adjustment plate 10 as a whole can be rotated in the horizontal direction about the arc-shaped slide groove 101. Combined with the horizontal angle mark 102 indicated by the V-shaped notch 116, the antenna 5 can be rotated to a preset horizontal angle, and then the fastening bolts 13 on the inner clamping plate 120 are tightened to complete the horizontal angle adjustment of the antenna 5.

[0058] In this embodiment, the vertical angle adjustment device includes a fixed base 20, which is a U-shaped plate structure. The fixed base 20 includes a first base body with a planar structure and a group of vertical arms 201 with relative ear-shaped plate structures arranged at both ends of the first base body. The second adjustment plate 11 also includes a group of rotating arms 110 with relative ear-shaped plate structures arranged at both ends of the main body plate. The vertical arm 201 and the rotating arm 110 are connected through an adjustment component and the vertical arm 201 and the rotating arm 110 can rotate relative to each other within a certain angle range in the vertical direction.

[0059] The rotating arm 110 is provided with a first slot hole 111 close to the arc surface of the main plate and an arc groove 113 relatively far away from the arc surface of the main plate. The vertical arm 201 is provided with a first adjustment hole 202 and a second adjustment hole 203. The adjustment assembly includes a first adjustment bolt 22 and a second adjustment bolt 23. The first adjustment bolt 22 passes through the first adjustment hole 202 and the first slot hole 111 in sequence, and a matching nut is provided at the end. The second adjustment bolt 23 passes through the second adjustment hole 203 and the arc groove 113 in sequence, and a matching nut is provided at the end.

[0060] In some other embodiments, a second slot hole 112 is provided on the rotating arm 110, which is relatively away from the arc surface of the main plate and close to the inner arc surface of the arc slide groove 113. The second slot hole 112 is connected to the arc slide groove 113 as a whole. The first slot hole 111 and the second slot hole 112 are collinear and are both on the central plane in the width direction of the rotating arm 110, so that the vertical arm 201 and the rotating arm 110 can be translated a certain distance in the horizontal direction.

[0061] Combine Figure 4 and Figure 5 As shown, the main body of the second adjustment plate 11 is semicircular. The outer side of the curved main body of the second adjustment plate 11 and the outer side of the curved first adjustment plate 10 are arc surfaces of equal radius. During operation, the two arc surfaces form a close fit with a large contact area, facilitating smooth adjustment of the horizontal angle and generating a large friction force to enhance the horizontal load-bearing capacity of the device.

[0062] Two second mounting holes 115 are formed through the curved surface of the curved main body of the second adjustment plate 11, and the two second mounting holes 115 are located at the center plane of the width of the curved main body of the second adjustment plate 11. The spacing between the two second mounting holes 115 is the same as the spacing between the two fourth mounting holes 1200 on the inner clamping plate 120 and the spacing between the two threaded holes 1210 on the outer clamping plate 121, so that the first adjustment plate 10, the second adjustment plate 11, and the fastening assembly can be connected as a whole using the fastening bolts 13.

[0063] like Figure 5 As shown, specifically, the first slot hole 111 and the second slot hole 112 are long slots, both ends of the long slots are arc-shaped, and one end of the second slot hole 112 is arc-shaped and integrated with the arc sliding groove 113.

[0064] like Figure 5 As shown, the first slot hole 111 and the second slot hole 112 are arranged on the central plane of the width direction of the rotating arm 110, that is, the center 1 1110 and the center 2 1111 of the first slot hole 111 and the center 3 1120 and the center 4 1121 of the second slot hole 112 are collinear and all on the central plane of the width direction of the rotating arm 110.

[0065] like Figure 5 As shown, the center point 1121 of the second slot hole 112 falls on the center arc line of the arc slot 113, and the distance L1 between the center point 1110 of the first slot hole 111 and the center point 1111 of the first slot hole 111 is equal to the distance L2 between the center point 1120 of the second slot hole 112 and the center point 1121 of the second slot hole 112.

[0066] like Figure 5 As shown, the arc groove 113 is an arc-shaped incision with a specific groove width, which is constructed with the second center 1111 of the first slot hole 111 as the center and the distance L3 between the second center 1111 of the first slot hole 111 and the fourth center 1121 of the second slot hole 112 as the radius, and the line connecting the center of the slot hole at one end and the second center 1111 of the first slot hole 111 forms an angle β with the central plane of the width direction of the rotating arm 110. Generally, the angle β is ≤60°.

[0067] The widths of the arc-shaped sliding groove 113 and the second slotted hole 112 are greater than the diameter of the second adjusting bolt 23 , and the width of the first slotted hole 111 is greater than the diameter of the first adjusting bolt 22 .

[0068] Specifically, on the rotating arm 110, near the top of the arc groove 113, evenly distributed vertical angle marks 114 are arranged along the arc of the arc groove 113. An angle indicator plate 21 is installed on one side of the rotating arm 110. A first fixing hole 210 and a second fixing hole 211 are provided on the angle indicator plate 21. The first adjusting bolt 22 passes through the first fixing hole 210, and the second adjusting bolt 23 passes through the second fixing hole 211. There is a fine pointed structure 212 at one end of the angle indicator plate 21 in the length direction facing the vertical angle mark 114 for pointing to the corresponding vertical angle mark 114 in real time.

[0069] Specifically, the vertical angle mark 114 is not set in the area covered by the head of the second adjusting bolt 23 to avoid the second adjusting bolt 23 rubbing against the surface of the vertical angle mark 114 and causing damage when rotating along the arc groove 113.

[0070] The spacing between the first adjustment hole 202 and the second adjustment hole 203 on the vertical arm 201 is consistent with the spacing between the first fixing hole 210 and the second fixing hole 211 on the angle indicator 21, as well as the radius of the arc-shaped slot 113 on the rotating arm 110 of the second adjustment plate 11. This allows the second adjustment plate 11 to rotate relative to the center 1111 of the first slot 111 on the fixing base 20, while the angle indicator 21 can point to the corresponding vertical angle mark 114 on the second adjustment plate 11 based on the actual relative angle between the two.

[0071] The angle indicator sheet 21 is a rectangular thin sheet structure. The center distance between the first fixing hole 210 and the second fixing hole 211 on the angle indicator sheet 21 is equal to the center distance between the first adjustment hole 202 and the second adjustment hole 203 on the fixing base 20.

[0072] When installing the vertical angle adjustment device, use the first adjusting bolt 22 to pass through the first fixing hole 210 on the angle indicator plate 21, the first adjusting hole 202 on the fixing seat 20, and the first slotted hole 111 on the rotating arm 110 of the second adjustment plate 11 in sequence, and screw on the matching nut; at the same time, use the second adjusting bolt 23 to pass through the second fixing hole 211 on the angle indicator plate 21, the second adjusting hole 203 on the fixing seat 20, and the second slotted hole 112 on the rotating arm 110 of the second adjustment plate 11 in sequence, and screw on the matching nut, thereby completing the assembly of the vertical angle adjustment device.

[0073] Combine Figure 1 、 Figure 4 and Figure 6As shown, when the vertical angle adjustment device of the two-dimensionally adjustable antenna mounting device is at a vertical inclination of zero degrees (i.e., no adjustment is required), and relative rotation between the fixing base 20 and the second adjustment plate 11 is not required, the second adjustment plate 11 needs to be pushed toward the fixing base 20 until the first adjustment bolt 22 abuts against the center point 1110 of the first slot 111. At this point, the bolt head of the first adjustment bolt 22 is embedded in the avoidance groove 1211 of the outer clamping plate 121, and under the combined action of the first slot 111 and the second slot 112, relative rotation between the fixing base 20 and the second adjustment plate 11 is prevented. At this point, the antenna 5 is closer to the mounting pole 4, reducing the cantilever length of the device relative to the mounting pole 4 and improving structural stability, thereby enhancing the reliability of the two-dimensionally adjustable antenna mounting device.

[0074] When the vertical angle needs to be adjusted, the first adjustment bolt 22 and the second adjustment bolt 23 are loosened, and the antenna 5, which is integrally connected to the second adjustment plate 11, is pushed away from the fixing base 20 until the second adjustment bolt 23 is out of the range of the second slot 112 and enters the arc groove 113, while the first adjustment bolt 22 remains in the first slot 111. The antenna 5, which is integrally connected to the first and second adjustment plates 10 and 11, is then rotated so that the antenna 5 rotates relative to the center 1111 of the first slot 111 on the rotating arm 110 of the second adjustment plate 11. In conjunction with the vertical angle mark 114 pointed to by the fine point structure 212 of the angle indicator 21, the antenna 5 can be rotated to a predetermined vertical angle. The first and second adjustment bolts 22 and 23 are then tightened to complete the vertical angle adjustment of the antenna 5.

[0075] In this embodiment, the mounting device also includes a clamping device for clamping the mounting rod 4, and the clamping device includes two groups of relatively arranged U-shaped clamps 30 and screw assemblies 31. The clamps 30 include a second base body with a planar structure and a clamping wall 302 connected to the second base body. The second base body is provided with two third mounting holes 300 and two fourth fixing holes 301. The mounting rod 4 is clamped by the two groups of clamps 30 and fixed by the screw assembly 31 through the third mounting hole 300. The fourth fixing hole 301 is used to cooperate with the bolt to fix it with the fixing seat 20 of the vertical angle adjustment device.

[0076] The first base of the fixing base 20 has two third fixing holes 200 symmetrically arranged about the longitudinal center plane of the first base. The spacing between the two third fixing holes 200 is the same as the spacing between the two fourth fixing holes 301 on the clamp 30, so that bolts can be inserted through the third fixing holes 200 on the fixing base 20 and the fourth fixing holes 301 on the clamp 30 to connect the two together.

[0077] The two third mounting holes 300 are symmetrical about the center plane of the first base in the longitudinal direction, and the two fourth fixing holes 301 are symmetrical about the center plane of the first base in the longitudinal direction. The distance between the two third mounting holes 300 is greater than the diameter of the conventional mounting rod 4.

[0078] Preferably, the clamping wall 302 has a serrated structure 303, which can effectively engage with a mounting rod 4 of a conventional diameter. This allows the clamp 30 to be stably engaged with the mounting rod 4 when a predetermined preload force is applied to the screw assembly 31. This ensures that the two-dimensionally adjustable antenna mounting device is stably engaged with the mounting rod 4.

[0079] The two-dimensionally adjustable antenna installation device of the present invention can simultaneously realize a wide range of adjustment of horizontal angles and vertical angles, and thus has a very wide range of applications.

[0080] The first adjustment plate 10 in the two-dimensional adjustable antenna mounting device of the present invention adopts an arc-shaped plate structure, which improves the structural strength while making the device smaller in size, thereby making the two-dimensional adjustable antenna mounting device reliable and light in weight.

[0081] The vertical angle adjustment device in the two-dimensionally adjustable antenna mounting device of the present invention brings the antenna 5 closer to the mounting pole 4 when the vertical inclination angle is zero degrees (i.e., no adjustment is made), thereby reducing the cantilever length of the device relative to the mounting pole 4 and having better structural stability, thereby making the two-dimensionally adjustable antenna mounting device more reliable.

[0082] The present invention is applicable to many scenarios, for example, it can be conveniently used in scenarios with flexible site deployment requirements, such as venue antennas and small cell antennas.

[0083] The two-dimensional adjustable antenna installation device created by the present invention has simple and quick installation and angle adjustment steps.

[0084] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which are protected by the present invention.
