It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0031] It should be understood that the reference to "one embodiment" throughout the specification means that the specific features, structures or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the "in one embodiment" that appears throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0032] The following describes in detail a base station antenna adjustment device provided by the present invention by listing specific embodiments.

[0033] Reference Figure 1 The base station antenna adjustment device of the embodiment of the present invention includes an antenna module 30, a turntable 20, a first transmission member, a second transmission member, a slider 41, a first driving mechanism and a second driving mechanism 50; the turntable 20 is fixedly connected to the antenna module 30 and the first transmission member respectively, the first transmission member is rotatably connected to the second transmission member through the slider 41, the slider 41 is connected to the first driving mechanism, and the second transmission member is connected to the second driving mechanism 50; the first driving mechanism is used to drive the slider 41 to move relative to the first transmission member, and the second driving mechanism 50 is used to drive the second transmission member to move, so that the first transmission member drives the turntable 20 to rotate, and the turntable 20 drives the antenna module 30 to rotate.

[0034] Specifically, if Figure 1As shown, the base station antenna adjustment device of this embodiment includes an antenna module 30, a turntable 20, a first transmission member, a second transmission member, a slider 41, a first drive mechanism and a second drive mechanism 50. The antenna module 30 can receive and transmit signals to realize signal transmission between the base station and the external communication device. The turntable 20 can be a circular, elliptical, square or other shaped structure. The axis of the turntable 20 is fixedly connected to the first transmission member and can rotate around the axis driven by the first transmission member. The surface of the turntable 20 is connected with the antenna module 30. Preferably, the turntable 20 can be set to rotate in the horizontal direction, and the antenna module 30 and the turntable 20 are vertically connected so that the antenna module 30 rotates synchronously with the turntable 20 in the vertical direction to improve the signal receiving and transmitting range of the antenna module 30. The first transmission member is fixedly connected to the slider 41, and the slider 41 is rotatably connected to the second transmission member, which indirectly realizes the rotation connection between the first transmission member and the second transmission member. The slider 41 is connected to a first driving mechanism, and the second transmission member is connected to a second driving mechanism 50. The first driving mechanism and the second driving mechanism 50 can be any one or more forms of electric drive, pneumatic drive, hydraulic drive and mechanical drive. The specific driving form is not limited in this embodiment.

[0035] The first driving mechanism drives the slider 41 to move relative to the first transmission member, so that the position of the slider 41 on the first transmission member changes, which is equivalent to changing the eccentricity between the force-bearing part of the first transmission member and the turntable 20. When the eccentricity changes, the range and amplitude of the turntable 20 driven by the first transmission member will also change accordingly. When the first transmission member moves the same distance, when the eccentricity is small, the rotation range and rotation amplitude of the turntable 20 will be correspondingly reduced, and when the eccentricity is large, the rotation range and rotation amplitude of the turntable 20 will be correspondingly increased. The second driving mechanism 50 drives the second transmission member to move, and then the second transmission member drives the first transmission member to move through the slider 41, and the first transmission member drives the turntable 20 fixedly connected thereto to rotate, thereby realizing the rotation of the antenna module 30 on the turntable 20. With the cooperation of the first driving mechanism and the second driving mechanism 50, the angle of the turntable 20 can be adjusted within different ranges, effectively expanding the adjustment range of the angle of the antenna module 30, and at the same time, the rotation amplitude of the turntable 20 can be controlled to achieve precise adjustment of the angle of the antenna module 30. Preferably, multiple antenna modules 30 may be provided and connected to the turntable 20, and the multiple antenna modules 30 may be distributed in an array on the turntable 20 to reduce signal interference between the antenna modules 30. Of course, the more antenna modules 30 there are, the greater the rotational force that needs to be provided when the turntable 20 rotates. Therefore, the specific number of antenna modules 30 needs to be determined according to the driving force output to the turntable 20 by the first driving mechanism and the second driving mechanism 50. The specific number of antenna modules 30 is not limited in this embodiment.

[0036] In the embodiment of the present invention, the base station antenna adjustment device drives the slider 41 to move relative to the first transmission member through the first driving mechanism, which can change the range and amplitude of the rotation of the turntable 20 driven by the first transmission member, and drives the second transmission member to move through the second driving mechanism 50, so that the second transmission member drives the first transmission member to move through the slider 41, and then the first transmission member drives the turntable 20 fixedly connected thereto to rotate. With the cooperation of the first driving mechanism and the second driving mechanism 50, this device can realize the angle adjustment of the turntable 20 within different ranges, effectively expand the adjustment range of the angle of the antenna module 30, further expand the signal reception and transmission range of the base station antenna, and avoid the influence of local obstacles on signal transmission. At the same time, the device can also control the rotation amplitude of the turntable 20, realize the precise adjustment of the angle of the antenna module 30, enhance the accuracy of signal transmission, and improve the transmission quality.

[0037] Optionally, refer to Figures 1 to 3 The turntable 20 is a semicircular structure, and the device also includes a first shell 10 and a support frame; a receiving cavity is provided in the first shell 10, and the turntable 20, the first transmission member, the second transmission member and the slider 41 are all arranged in the receiving cavity; a semicircular groove is provided on the surface of the first shell 10 close to the antenna module 30, and the support frame passes through the semicircular groove and is fixedly connected to the turntable 20 and the antenna module 30 respectively.

[0038] Specifically, if Figure 1 and Figure 2 As shown, the turntable 20 is a semicircular structure, which can save the processing materials of the turntable 20 while meeting the maximum range of angle adjustment of the antenna module 30, and control the processing cost. The first shell 10 can be a shell of any shape such as square, circular, etc. It has good rigidity performance, can play a certain protective role on the mechanism in the shell, and reduce the risk of the mechanism in the shell being bumped. A accommodating cavity is provided in the first shell 10, and the turntable 20, the first transmission member, the second transmission member and the slider 41 are all arranged in the accommodating cavity. In the appearance structure of the first shell 10, the turntable 20, the first transmission member, the second transmission member and the slider 41 cannot be intuitively seen, so that the turntable 20, the first transmission member, the second transmission member and the slider 41 can be prevented from accumulating dust during long-term use, ensuring their normal operation. A signal transmission device 60 is also provided in the first shell 10, and the antenna module 30 is connected to the signal transmission device 60. Through the cooperation of the antenna module 30 and the signal transmission device 60, signal transmission between the base station wired communication network and the wireless terminal can be realized. The support frame is disposed above the turntable 20 and is used to support the antenna module 30, that is, the turntable 20 and the antenna module 30 are fixedly connected together through the support frame. Figure 3As shown, a semicircular groove is provided on the surface of the first shell 10 near the antenna module 30. The position of the semicircular groove corresponds to the position of the turntable 20 in the accommodating cavity. The size of the semicircular groove is determined according to the edge size of the turntable 20. The support frame passes through the semicircular groove and is fixedly connected to the turntable 20 and the antenna module 30 respectively. When the turntable 20 rotates, the support frame rotates along the semicircular groove to avoid the phenomenon of rotation offset, which can enhance the stability of the antenna module 30 during rotation. The support frame can be formed by a shaft rod and a support plate vertically fixedly connected, and it can also be a structure processed in one piece. The shaft rod is fixedly connected to the surface of the turntable 20, and the antenna module 30 is connected to the surface of the support plate. The height of the shaft rod is determined according to the height of the accommodating cavity in the first shell 10. The higher the height of the accommodating cavity, the higher the height of the shaft rod. The length of the support plate is determined according to the number of antenna modules 30. The more the number of antenna modules 30, the longer the support plate. The specific parameters of the shaft rod and the support plate are not limited in this embodiment.

[0039] Optionally, refer to Figure 1 The first transmission member is a slide groove 42, and the device also includes a driving shaft 43; the slider 41 is embedded in the slide groove 42, and the slider 41 is sleeved on the driving shaft 43, and the end of the driving shaft 43 away from the turntable 20 is connected to the first driving mechanism; the first driving mechanism drives the driving shaft 43 to move in the slide groove 42, so that the slider 41 slides in the slide groove 42.

[0040] Specifically, if Figure 1 As shown, the first transmission member is a slide groove 42, and the slider 41 is embedded in the slide groove 42 and can slide in the slide groove 42. The second transmission member is connected to the slide groove 42 through the slider 41. When the second transmission member moves, the slider 41 is driven to squeeze the inner wall of the slide groove 42, so that the slide groove 42 drives the turntable 20 to rotate. The slider 41 is sleeved on the drive shaft 43, and the slider 41 cannot move in the axial direction of the drive shaft 43. The end of the drive shaft 43 away from the turntable 20 is connected to the first driving mechanism, and the first driving mechanism drives the drive shaft 43 to telescopically translate in the slide groove 42, thereby driving the slider 41 to slide and translate in the slide groove 42. The first driving mechanism of this embodiment can be arranged in the accommodating cavity of the first shell 10, connected to the control panel outside the first shell 10, and the first driving mechanism can be controlled by the control panel. It can also be directly arranged outside the first shell 10 for manual drive. The specific setting form of the first driving mechanism is not limited in this embodiment.

[0041] Optionally, the driving shaft 43 is a screw rod, and the first driving mechanism drives the screw rod to rotate and translate in the sliding groove 42 so that the sliding block 41 slides in the sliding groove 42 .

[0042] Specifically, the driving shaft 43 can be a screw rod, and the slider 41 is threadedly connected to the screw rod. The screw rod is driven to rotate by the first driving mechanism, driving the slider 41 to translate in the slide groove 42, so that the slider 41 can slide smoothly in the slide groove 42, thereby improving the stability of the rotation of the turntable 20.

[0043] Optionally, refer to Figure 1 The second transmission member includes a first connecting rod 44 and a second connecting rod 45 ; one end of the first connecting rod 44 is fixedly connected to the second driving mechanism 50 , and the other end is rotatably connected to the second connecting rod 45 ; the other end of the second connecting rod 45 is rotatably connected to the slider 41 .

[0044] Specifically, if Figure 1 As shown, the second transmission member includes a first connecting rod 44 and a second connecting rod 45. One end of the first connecting rod 44 is fixedly connected to the second driving mechanism 50, and rotates under the drive of the second driving mechanism 50. The other end of the first connecting rod 44 is rotatably connected to the second connecting rod 45. The driving force output by the second driving mechanism 50 is transmitted to the second connecting rod 45 through the first connecting rod 44, driving the second connecting rod 45 to swing. The other end of the second connecting rod 45 is rotatably connected to the slider 41. Under the drive of the first connecting rod 44, the second connecting rod 45 drives the slider 41 to squeeze the chute 42, so that the chute 42 drives the turntable 20 to rotate. Due to the existence of the rotational connection relationship between the first connecting rod 44 and the second connecting rod 45, and between the second connecting rod 45 and the slider 41, at the moment when the second driving mechanism 50 is started or closed, the impact of the driving force can be reduced to a certain extent, so that the first connecting rod 44 and the second connecting rod 45 can transmit the driving force more stably, avoid the rotation impact of the turntable 20, and further improve the rotation reliability of the turntable 20.

[0045] Optionally, refer to Figure 2 The first shell 10 is provided with heat dissipation holes 13 on its peripheral side.

[0046] Specifically, if Figure 2 As shown, heat dissipation holes 13 are provided on the circumferential side of the first shell 10. The heat dissipation holes 13 may be in the form of shutters or in the form of multiple holes. During operation, a large amount of heat will be generated in the accommodating cavity of the first shell 10, causing the temperature in the accommodating cavity to rise. Excessive temperature may cause malfunctions of the first transmission member, the second transmission member, the gear plate, etc. in the accommodating cavity, and even cause safety accidents. Therefore, heat dissipation holes 13 are provided on the circumferential side of the first shell 10. The heat dissipation holes 13 can be used to dissipate heat from the accommodating cavity to avoid excessively high temperatures in the accommodating cavity and ensure the normal operation of the device.

[0048] Specifically, the base station antenna adjustment device further includes a cleaning mechanism 70, which can clean the surface of the antenna module 30 to prevent dust from accumulating on the surface of the antenna module 30. Figure 4 As shown, the cleaning mechanism 70 includes a gear shaft 71, a first gear 72 and a cleaning roller 73. The first gear 72 is sleeved on the gear shaft 71. The first gear 72 and the gear shaft 71 can be fixedly connected together by a spline, so that the first gear 72 and the gear shaft 71 rotate synchronously. The edge of the turntable 20 is a toothed structure. The first gear 72 is meshed and connected with the turntable 20. When the turntable 20 rotates, the first gear 72 rotates in the opposite direction, thereby driving the gear shaft 71 to rotate. The cleaning roller 73 is fixedly connected to the gear shaft 71 and rotates synchronously with the gear shaft 71. The surface of the cleaning roller 73 is wrapped with a cleaning brush 74, and the dust on the surface of the antenna module 30 can be cleaned by the cleaning brush 74. It should be noted that the sum of the heights of the cleaning roller 73 and the gear shaft 71 should be close to the sum of the heights of the support frame 14 and the antenna module 30, so as to ensure that the cleaning brush 74 on the surface of the cleaning roller 73 can clean various parts of the surface of the antenna module 30. In addition, the diameter of the first gear 72 should be set according to the distance between the cleaning roller 73 and the antenna module 30 to ensure that the cleaning brush 74 on the surface of the cleaning roller 73 can touch the surface of the antenna module 30 .

When there are multiple cleaning rollers 73, a support plate 75 is used to support the multiple cleaning rollers 73. The side of the support plate 75 away from the cleaning rollers 73 is fixedly connected to the gear shaft 71. The support plate 75 rotates synchronously with the gear shaft 71, driving the multiple cleaning rollers 73 on the support plate 75 to rotate synchronously, which can effectively improve the cleaning efficiency.

[0051] Optionally, refer to Figure 4 The device also includes a second gear 76, a rack 77 and a liquid spraying mechanism 80; the second gear 76 is non-rotatably mounted on the gear shaft 71 and meshingly connected with the rack 77; the liquid spraying mechanism 80 is connected to the rack 77, and when the second gear 76 rotates, the rack 77 drives the liquid spraying mechanism 80 to operate, so that the liquid spraying mechanism 80 sprays cleaning liquid to clean the surface of the antenna module 30.

[0052] Specifically, if Figure 4 As shown, the cleaning mechanism 70 also includes a second gear 76, a rack 77 and a liquid spraying mechanism 80. The second gear 76 is non-rotatably sleeved on the gear shaft 71 and rotates synchronously with the gear shaft 71. The second gear 76 is meshedly connected with the rack 77. The rack 77 can be set in the tooth groove and slide in the tooth groove to avoid displacement during the sliding process. The rotation of the second gear 76 can drive the rack 77 to perform horizontal reciprocating motion. The liquid spraying mechanism 80 is connected to the rack 77. When the second gear 76 rotates toward the liquid spraying mechanism 80, the rack 77 can be pushed to move toward the liquid spraying mechanism 80, thereby operating the liquid spraying mechanism 80, so that the liquid spraying mechanism 80 sprays cleaning liquid to clean the surface of the antenna module 30, further improving the cleaning effect.

A first spring 85 is provided in the air bag 84. Under the support of the first spring 85, the air bag 84 always maintains a constant size, which facilitates the injection of cleaning liquid into the air bag 84. In the process of pushing the first piston 83 to move in the second housing 81 by the push rod 82, the closed cavity will be squeezed by the first piston 83. Since the other end of the closed cavity is squeezed by the air bag 84, the pressure in the closed cavity will increase at this time, and the air bag 84 will be squeezed at the same time, so that the first spring 85 in the air bag 84 is deformed. In this process, the volume of the air bag 84 gradually decreases. The airbag 84 is provided with a liquid inlet 86 and a liquid outlet 87, both of which penetrate the second shell 81. Cleaning liquid can be injected into the airbag 84 through the liquid inlet 86, and the cleaning liquid in the airbag 84 can be discharged through the liquid outlet 87. The airbag 84 can store cleaning liquid. When the push rod 82 pushes the first piston 83 to move in the second shell 81, the closed cavity squeezes the airbag 84, so that the cleaning liquid in the airbag 84 is discharged through the liquid outlet 87. The liquid outlet 87 is connected to the support frame 14, and a foldable tube can be connected to the liquid outlet 87, which is connected to the support frame 14, thereby simplifying the spatial layout of the liquid spraying mechanism 80. The support frame 14 is a hollow structure, and a through hole is opened on the surface of the support frame 14 close to the antenna module 30, so that the cleaning liquid in the airbag 84 can be discharged to the inside of the support frame 14 through the liquid outlet 87, and then sprayed to the antenna module 30 through the through hole on the surface of the support frame 14 to clean the surface of the antenna module 30.

[0055] Optionally, refer to Figure 5 The through hole is connected to an atomizing nozzle 15.

[0056] Specifically, if Figure 5 As shown, the through holes on the surface of the support frame 14 are connected to the atomizing nozzle 15. By spraying the cleaning liquid through the atomizing nozzle 15, the cleaning liquid can be sprayed more evenly onto the surface of the antenna module 30, thereby improving the cleaning effect.

[0057] Optionally, refer to Figure 5 The liquid spraying mechanism 80 also includes a third shell 88; a second piston 89 and an air port 91 are provided in the third shell 88, the second piston 89 is communicated with the closed cavity, and the air port 91 is communicated with the accommodating cavity 11; the closed cavity squeezes the second piston 89 so that the gas in the closed cavity flows into the accommodating cavity 11 through the air port 91.

[0058] Specifically, if Figure 5 As shown, the liquid spraying mechanism 80 also includes a third housing 88, which is connected to the closed cavity. A second piston 89 and an air port 91 are arranged in the third housing 88. The second piston 89 is connected to a second spring 90. When the second spring 90 is not under force, the second piston 89 is in a state of closing the air port 91. When the pressure in the closed cavity is too high, the second piston 89 is pushed to move in the third housing 88, so that the second piston 89 squeezes the second spring 90, thereby opening the air port 91, and the gas in the closed cavity can be discharged through the air port 91. It should be noted that in this embodiment, the elastic potential energy of the second spring 90 is greater than the elastic potential energy of the first spring 85 in the aforementioned airbag 84. In the process of increasing pressure in the closed cavity, the first spring 85 is first deformed by squeezing the airbag 84, and then after the pressure in the closed cavity increases to a certain extent, the second piston 89 is squeezed to deform the second spring 90, and the air port 91 is opened for exhaust. The air port 91 is in communication with the accommodating cavity 11 of the first shell 10 , and the air in the closed cavity directly flows into the accommodating cavity 11 through the air port 91 , dissipating the heat of the accommodating cavity 11 and preventing the temperature in the accommodating cavity 11 from being too high.

[0059] The present invention also discloses a base station, which includes the base station antenna adjustment device described in any one of the above items.

[0060] Specifically, the base station provided in the embodiment of the present invention is configured with the above-mentioned base station antenna adjustment device, which can realize the angle adjustment of the base station antenna, expand the signal reception and transmission range of the base station, avoid the influence of local obstacles on the base station signal transmission, thereby effectively enhancing the reliability of the base station signal transmission and the quality of signal transmission.
