Description

Technical Field

[0001] The present invention relates to the technical field of base station antennas, and in particular to a base station antenna angle adjustment device. Background Art

[0002] In mobile communication networks, accurate adjustment of the downtilt and azimuth angles of base station antennas is crucial to ensure network coverage quality and signal strength. The downtilt angle of the antenna determines the vertical coverage of the signal, while the azimuth angle determines the horizontal direction of the signal. Therefore, accurate adjustment of these two angles is a key link in base station deployment and maintenance.

[0003] Currently, the downtilt angle and horizontal azimuth angle of base station antennas are adjusted mainly in two ways. The first method relies on the traditional manual adjustment method, that is, the operator needs to first loosen the fasteners that fasten the antenna to the bracket, then manually move or rotate the antenna to the desired angle, and finally lock the fasteners to fix the position of the antenna. However, this method has significant inconveniences. Especially in the process of adjusting base station antennas that require a large downtilt angle, since the azimuth adjustment and the position of the fasteners are relatively far away from the pole (the structure supporting the antenna), it is often difficult for operators to hold the antenna steady with one hand while using the other hand to complete the locking operation of the fasteners. This not only increases the complexity of the operation, but may also lead to a decrease in adjustment accuracy, affecting the actual coverage effect of the base station.

[0004] Another adjustment scheme is to use an electronically controlled motor to automatically adjust the downtilt and azimuth angles of the base station antenna. Although this method can greatly improve the accuracy and efficiency of adjustment in theory, it faces many limitations in practical applications. Since most base station towers do not have facilities to power the motor, the application scenarios of this electronically controlled adjustment scheme are very limited and it is difficult to implement in large quantities on a wide range.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 11 The present invention provides a base station antenna angle adjustment device for adjusting the azimuth angle and downtilt angle of the base station antenna 100, which includes an active adjustment mechanism 300 and a passive adjustment mechanism 400. The upper end of the base station antenna 100 is connected to the holding pole 200 through the active adjustment mechanism 300, and the lower end of the base station antenna 100 is connected to the holding pole 200 through the passive adjustment mechanism 400.

[0023] The active adjustment mechanism 300 includes an azimuth adjustment component 1, an inclination adjustment component 2 and an adjustment locking component 3. The inclination adjustment component 2 includes a first angle arm seat 21, a first adjustment arm 22 and a first transmission component 23. The first angle arm seat 21 is fixed on the holding pole 200. The first adjustment arm 22 is connected to the first angle arm seat 21 through the first transmission component 23. The first adjustment arm 22 moves radially along the holding pole 200 under the transmission of the first transmission component 23.

[0024] The azimuth adjustment assembly 1 includes a first support plate 11 and a second transmission assembly 12. The first support plate 11 is fixed to the upper end of the base station antenna 100. The second transmission assembly 12 is arranged on the first adjustment arm 22. The first support plate 11 is rotatably connected to the first adjustment arm 22 through the second transmission assembly 12. The first support plate 11 rotates around the first adjustment arm 22 under the transmission of the second transmission assembly 12, thereby driving the base station antenna 100 to rotate synchronously.

[0025] The first transmission assembly 23 and the second transmission assembly 12 are both provided with an adjusting and locking assembly 3. The adjusting and locking assembly 3 connected to the first transmission assembly 23 is used to drive and lock the first transmission assembly 23, and the adjusting and locking assembly 3 connected to the second transmission assembly 12 is used to drive and lock the second transmission assembly 12.

[0026] The driven adjustment mechanism 400 includes a second angle arm seat 4, a first driven adjustment component and a second driven adjustment component. The second angle arm seat 4 is fixed on the holding pole 200, one end of the first driven adjustment component is rotatably connected to the second angle arm seat 4, the other end of the first driven adjustment component is rotatably connected to one end of the second driven adjustment component, and the other end of the second driven adjustment component is fixedly connected to the lower end of the base station antenna 100.

[0027] In the process of adjusting the downtilt angle, the adjusting locking assembly 3 is used to drive the first transmission assembly 23 to drive the first adjustment arm 22 to move along the radial direction of the pole 200, thereby adjusting the distance between the upper end of the base station antenna 100 and the pole 200. At the same time, the first driven adjustment assembly rotates a certain angle with the axial direction perpendicular to the pole 200 as the axis with the movement of the first adjustment arm 22, thereby adjusting the downtilt angle of the base station antenna 100. In the process of adjusting the azimuth angle, the adjusting locking assembly 3 is used to drive the second transmission assembly 12 to drive the first support plate 11 to rotate around the tilt adjustment assembly 2. At the same time, the second driven adjustment assembly rotates synchronously around the first driven adjustment assembly with the rotation of the first support plate 11, thereby adjusting the azimuth angle of the base station antenna 100. The base station antenna angle adjustment device of the present invention can effectively solve the problem of inconvenience in adjusting the downtilt angle and horizontal azimuth angle of the base station antenna, reduce the adjustment time, and improve the adjustment efficiency.

[0028] Specifically, Figure 2As shown, the inclination adjustment assembly 2 includes a first angle arm seat 21, a first adjustment arm 22 and a first transmission assembly 23. A first fixing bracket 201 is installed on the holding rod 200. One end of the first angle arm seat 21 is fixed to the first fixing bracket 201. The other end of the first angle arm seat 21 has two ears extending along the axial direction of the holding rod 200. Each ear is provided with a first slide groove 211 extending along the axial direction of the holding rod 200. The first adjustment arm 22 is sandwiched between the two ears. The first adjustment arm 22 includes two first arms 221 arranged opposite to each other. The holding rod 200 is located between the two first arms 221. Each first arm 221 is provided with a second slide groove 222 extending along the length direction of the first arm 221.

[0029] The two first arms 221 may be integrally formed or separately provided, which is not limited here.

[0030] The first transmission assembly 23 includes a first driving gear 231 and at least one rack 232. Top edges and top edges are extended from opposite sides of the two first arms 221, the rack 232 is fixed to the bottom edge of the inner side of the first arm 221, and the rack 232 is arranged at the lower side of the second slide slot 222 along the length direction of the first arm 221. Specifically, the tooth portion of the rack 232 is arranged close to the lower side edge of the second slide slot 222, and the uppermost end of the tooth portion of the rack 232 is slightly lower than the slide slot opening of the second slide slot 222. The two second slide slots 222 on the first adjustment arm 22 are placed inside the two first slide slots 211 of the first angle arm seat 21. The first driving gear 231 is arranged perpendicular to the first support arm 221, and the two ends of the first driving gear 231 are respectively inserted into the second slide groove 222 and the first slide groove 211 in sequence, and the first driving gear 231 is engaged with the rack 232, and the first adjusting arm 22 is driven to slide radially along the holding pole 200 by driving the first driving gear 231.

[0031] Specifically, the first driving gear 231 is a spur gear, the middle portion of the first driving gear 231 is a gear, and both end portions are cylindrical.

[0032] The two ends of the first driving gear 231 are disposed in the two second slide grooves 222 of the first adjusting arm 22, and the first driving gear 231 can slide in the two second slide grooves 222 of the first adjusting arm 22. At the same time, the two ends of the first driving gear 231 are also placed in the two first slide grooves 211 of the first angle arm seat 21, and the first driving gear 231 can also slide in the two first slide grooves 211 of the first angle arm seat 21. When the first driving gear 231 is rotated, the first driving gear 231 just slides in the second slide groove 222 of the first adjusting arm 22.

[0033] When the downtilt angle needs to be adjusted, it is only necessary to rotate the first driving gear 231 so that the first driving gear 231 can slide in the second slide groove 222 of the first adjusting arm 22. Since the two ends of the first driving gear 231 are also placed in the two first slide grooves 211 of the first angle arm seat 21, the first driving gear 231 cannot move in the horizontal direction (i.e., the radial direction of the pole), and only the first adjusting arm 22 can move in the horizontal direction, thereby driving the upper end of the base station antenna 100 to move in the horizontal direction to complete the downtilt angle adjustment.

[0034] like Figure 2 and Figure 3 As shown, when the downtilt angle of the base station antenna 100 changes from a small angle to a large angle, the first driving gear 231 also moves from the lower end of the first slide slot 211 to the upper end of the first slide slot 211 to adapt to the change in the downtilt angle.

[0035] like Figure 4-Figure 6 As shown, the azimuth adjustment assembly 1 includes a first support plate 11, a second transmission assembly 12 and a fixing seat 13. The first support plate 11 is fixed to the upper end of the base station antenna 100 through the base station antenna bracket 101. The first support plate 11 is a U-shaped plate. The first support plate 11 includes two clamping plates arranged opposite to each other. The end of the first adjustment arm 22 close to the base station antenna 100 is clamped between the two clamping plates. One or more first through holes 2201 are provided on the top edge of at least one first support arm 221, and a pair of second through holes 2202 are symmetrically provided at one end of the two first support arms 221 close to the base station antenna 100. A pair of third through holes 2203 are provided along the thickness direction of the end of the first adjustment arm 22 close to the base station antenna 100.

[0036] The second transmission assembly 12 includes a second driving gear 121, a long rotating shaft 122, a first bevel gear 123 and a second bevel gear 124. The number of the second driving gears 121 corresponds to the number of the first through holes 2201. The second driving gear 121 is arranged in the first through hole 2201 of the first support arm 221 along the thickness direction of the first adjustment arm 22, and can rotate in the first through hole 2201. The fixing seat 13 is fixed to the inner side of the first support arm 221, the long rotating shaft 122 is arranged on the fixing seat 13 along the length direction of the first adjustment arm 22, and the fixing seat 13 is provided with a fourth through hole, and the long rotating shaft 122 is arranged on the fixing seat 13 to rotate through the fourth through hole.

[0037] The first bevel gear 123 is inserted into the second through holes 2202 of the two first support arms 221 along the width direction of the first adjustment arm 22. The first bevel gear 123 includes a first bevel tooth located at the end and a second bevel tooth located in the middle. The first bevel tooth is meshed with the second driving gear 121 through the long rotating shaft 122. Both ends of the second bevel gear 124 are inserted into the third through hole 2203 and the fifth through hole 1101 of the first support plate 11 in sequence along the thickness direction of the first adjustment arm 22. The second bevel gear 124 is fixedly connected to the first support plate 11 and rotatably connected to the first adjustment arm 22. The second bevel gear 124 is meshed with the second bevel tooth in the middle of the first bevel gear 123.

[0038] The second driving gear 121 has a third beveled tooth at one end close to the long rotating shaft 122, and a cylindrical shape at one end away from the long rotating shaft 122. The cylindrical end of the second driving gear 121 is placed in the first through hole 2201 of the first arm 221. The long rotating shaft 122 includes a rotating shaft body and at least two fourth beveled teeth located on the rotating shaft body, one of which is located at one end of the rotating shaft body close to the base station antenna 100, and the other fourth beveled teeth are meshed with the third beveled teeth one by one, as shown in FIG. Figure 6 As shown in . The axis of the long rotating shaft 122 is parallel to the second sliding groove 222 of the first adjusting arm 22 .

[0039] Among them, the first bevel teeth, the second bevel teeth, the third bevel teeth and the fourth bevel teeth are all 45° bevel teeth.

[0040] like Figure 4 , Figure 6 and Figure 7 As shown, when the azimuth angle needs to be adjusted, any second driving gear 121 is rotated, and the second driving gear 121 drives the long rotating shaft 122 to rotate, and the rotation of the long rotating shaft 122 can drive the first bevel gear 123 to rotate, and the rotation of the first bevel gear 123 can drive the second bevel gear 124 to rotate, and the rotation of the second bevel gear 124 can drive the first support plate 11 and the base station antenna 100 to rotate relative to the pole 200, so as to complete the azimuth angle adjustment. Since a plurality of second driving gears 121 are arranged on the first adjusting arm 22 at intervals, no matter what the downtilt angle is, there can always be a second driving gear 121 near the pole 200, and the azimuth angle can be conveniently adjusted.

[0041] like Figure 2 and Figure 6 As shown, an adjusting locking assembly 3 is provided one by one on the first driving gear 231 and the plurality of second driving gears 121 . The adjusting locking assembly 3 is fixed on the inclination adjustment assembly 2 . Each adjusting locking assembly 3 is used to drive or lock the corresponding driving gear.

[0042] like Figure 8 and Fig. 9As shown, taking the first driving gear 231 as an example, one end of the first driving gear 231 is provided with a limiting tooth 2311, and the end surface of the first driving gear 231 provided with the limiting tooth 2311 is provided with a mounting hole 2312. The adjustment locking assembly 3 includes a mounting plate 31, an adjustment rod 32 and an adjustment knob 34. The mounting plate 31 is fixed on the ear of the first angle arm seat 21. The mounting plate 31 is provided with an avoidance hole 311. The limiting tooth 2311 passes through the avoidance hole 311 and extends out of the outside of the mounting plate 31. The adjustment rod 32 is rotatably arranged on the outside of the mounting plate 31. The side of the adjustment rod 32 facing the limiting tooth 2311 is provided with a limiting tooth group 321, and the limiting tooth group 321 is adapted to the limiting tooth 2311. The adjusting knob 34 includes a knob portion and a connecting portion. The connecting portion is matched with the mounting hole 2312 . The adjusting knob 34 is detachably mounted in the mounting hole 2312 of the first driving gear 231 through the connecting portion.

[0043] When the limiting tooth set 321 is meshed with the limiting tooth 2311, the adjusting locking assembly 3 can lock the first driving gear 231 to limit the rotation of the first driving gear 231. When the limiting tooth set 321 is separated from the limiting tooth 2311, the first driving gear 231 can be driven to rotate by rotating the adjusting knob 34.

[0044] Furthermore, the adjustment locking assembly 3 also includes a limit rod 33, which is used to limit the rotation position of the adjustment rod 32. A limit block 312 is also provided on the outer side of the mounting plate 31, one end of the limit rod 33 is rotatably connected to the mounting plate 31, and the other end of the limit rod 33 is elastically abutted against the limit block 312, and the limit block 312 is used to limit the rotation position of the limit rod 33. Among them, two tooth-shaped grooves 331 are provided on the side of the limit rod 33 facing the limit teeth 2311, and a tooth-shaped protrusion 322 is provided on the end of the adjustment rod 32 close to the limit rod 33. The adjustment rod 32 and the limit rod 33 are abutted through the tooth-shaped protrusion 322 and the tooth-shaped groove 331. By rotating the adjustment rod 32 to push the limit rod 33 to rotate toward the side close to the limit block 312, the tooth-shaped protrusion 322 switches between the two tooth-shaped grooves 331.

[0045] Among them, when the tooth-shaped protrusion 322 is embedded in the tooth-shaped groove 331 on the side close to the limiting tooth 2311, the limiting tooth group 321 is engaged with the limiting tooth 2311; when the tooth-shaped protrusion 322 is embedded in the tooth-shaped groove 331 on the side away from the limiting tooth 2311, the limiting tooth group 321 is separated from the limiting tooth 2311.

[0046] Furthermore, the adjustment locking assembly 3 also includes an elastic member 35, a limiting column 332 is provided on the side of the limiting rod 33 facing the limiting block 312, a limiting hole is provided on the limiting block 312, one end of the elastic member 35 is sleeved on the limiting column 332, and the other end of the elastic member 35 is embedded in the limiting hole to prevent the elastic member 35 from popping out during use.

[0047] The elastic member 35 may be a spring, but is not limited thereto.

[0048] In one embodiment, a first mounting column and a second mounting column are provided on the outer side of the mounting plate 31 , and the adjusting rod 32 and the limiting rod 33 are rotatably mounted on the mounting plate 31 through the first mounting column and the second mounting column respectively.

[0049] It can be understood that one end of the second driving gear 121 is also provided with a limiting tooth and a mounting hole, and the structure of the limiting tooth and the mounting hole of the second driving gear 121 is similar to the structure of the limiting tooth and the mounting hole of the first driving gear 231, and the connection method between the second driving gear 121 and the adjustment locking assembly 3 is similar to the connection method between the first driving gear 231 and the adjustment locking assembly 3, which will not be repeated here.

[0050] When the angle needs to be adjusted, the adjusting rod 32 is rotated until the tooth-shaped protrusion 322 is embedded in the tooth-shaped groove 331 on the side away from the limiting tooth 2311. At this time, the limiting tooth group 321 is separated from the limiting tooth 2311, and the angle is adjusted by rotating the adjusting knob 34. After the angle adjustment is completed, the adjusting rod 32 is rotated until the tooth-shaped protrusion 322 is embedded in the tooth-shaped groove 331 on the side close to the limiting tooth 2311. At this time, the limiting tooth group 321 is meshed with the limiting tooth 2311, which can limit the rotation of the driving gear and ensure that the angle remains unchanged after adjustment. Since the spring on the limiting rod 33 supports the limiting rod 33, and the limiting rod 33 clamps the adjusting rod 32, the adjusting rod 32 cannot change its state by itself without external force, thereby improving the stability of the angle adjustment.

[0051] like Fig.10 and Fig.11 As shown, the driven adjustment mechanism 400 includes a second angle arm seat 4, a first driven adjustment assembly and a second driven adjustment assembly, the first driven adjustment assembly includes a second adjustment arm 5 and a first rotating component 6, and the second driven adjustment assembly includes a second support plate 7 and a second rotating component 8. A second fixed bracket 202 is fixed to the pole 200, the second angle arm seat 4 is fixed to the pole 200 through the second fixed bracket 202, and the second support plate 7 is fixed to the lower end of the base station antenna 100 through the base station antenna bracket 101. One end of the second adjustment arm 5 is rotatably connected to the second angle arm seat 4 through the first rotating component 6, and the other end of the second adjustment arm 5 is rotatably connected to the second support plate 7 through the second rotating component 8. Among them, the first rotating component 6 is arranged perpendicular to the axial direction of the pole 200, and the second rotating component 8 is arranged parallel to the axial direction of the pole 200.

[0052] The two ends of the first rotating component 6 are respectively and sequentially arranged on the second angle arm seat 4 and the second adjusting arm 5, and the second adjusting arm 5 can rotate around the axial direction of the first rotating component 6. The two ends of the second rotating component 8 are respectively and sequentially arranged on the second adjusting arm 5 and the second supporting plate 7, and the second supporting plate 7 can rotate around the axial direction of the second rotating component 8.

[0053] The second support plate 7 is a U-shaped plate, and its structure is similar to that of the first support plate 11 , which will not be described in detail herein.

[0054] The first rotating component 6 may be a spur gear or a conventional rotating shaft, and the second rotating component 8 may be a helical gear or a conventional rotating shaft, as long as the rotating connection between the components can be achieved.

[0055] It should be noted that the driven adjustment mechanism 400 itself does not have the ability to drive rotation, but can rotate with the rotation of the tilt adjustment component 2 and the azimuth adjustment component 1, and finally realize the adjustment of the base station antenna angle. Specifically, in the process of adjusting the downward tilt angle, since the axial direction of the first rotating component 6 is parallel to the axial direction of the first driving gear 231, the second adjustment arm 5 can drive the lower end of the base station antenna to rotate along the axial direction of the first rotating component 6 during the movement of the first adjustment arm 22 to adapt to the adjustment of the tilt angle. In the process of adjusting the azimuth angle, since the axial direction of the second rotating component 8 is parallel to the axial direction of the second bevel gear 124, the second support plate 7 can drive the lower end of the base station antenna to rotate around the axial direction of the second rotating component 8 during the process of the second bevel gear 124 driving the first support plate 11 to rotate, so as to adapt to the adjustment of the azimuth angle.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
