Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0041] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

[0044] During the installation, maintenance, and network optimization of the spotlight antenna, it is necessary to adjust the pitch angle and horizontal azimuth angle of the spotlight antenna to make the signal of the adjusted spotlight antenna more stable and the coverage effect better. Among them, the pitch angle of the spotlight antenna refers to the angle between the maximum radiation direction of the spotlight antenna and the horizontal plane. For example, the pitch angle when the maximum radiation direction of the spotlight antenna is parallel to the horizontal plane is 0 degrees. The horizontal azimuth angle of the spotlight antenna refers to the deflection angle of the maximum radiation direction of the spotlight antenna around the axis perpendicular to the horizontal plane. For example, taking the maximum radiation direction of the spotlight antenna pointing to due north as the standard, adjust the maximum radiation direction of the spotlight antenna to the east or west by an angle. This angle is the horizontal azimuth angle of the spotlight antenna, that is, the horizontal azimuth angle when the maximum radiation direction of the spotlight antenna points to due north is 0 degrees.

[0045] See also Figures 1 to 3 , Figure 1 One of the structural schematic diagrams of the spotlight antenna assembly in some embodiments of the present application is shown, Figure 2 The second structural schematic diagram of the spotlight antenna assembly in some embodiments of the present application is shown. Figure 3The schematic diagram of the structure of the spotlight antenna in some embodiments of the present application is shown. The spotlight antenna assembly 100 provided in the embodiment of the present application includes a first mounting member 1, a spotlight antenna 2 and a first driving module 3. The first mounting member 1 is used to be mounted on a bearing surface. The spotlight antenna 2 includes a housing 21 and a worm gear profile 22 formed on the outer wall of the housing 21. The housing 21 is rotatably connected to the first mounting member 1. The worm gear profile 22 includes a plurality of worm gear teeth 221 arranged in a circular arc, and the arc center line of the worm gear profile 22 is colinear with the rotation axis of the housing 21. The first driving module 3 is arranged on the first mounting member 1. The first driving module 3 includes a first worm 31 and a first driver 32. The first worm 31 is meshed and connected with the worm gear profile 22. The first driver 32 is connected to the first worm 31 and is used to drive the first worm 31 to rotate. The first worm 31 can drive the spotlight antenna 2 to pitch and rotate around the rotation axis of the housing 21 through the worm gear profile 22.

[0046] The first mounting member 1 is used to be installed on the bearing surface. The first mounting member 1 can be fixedly connected to the bearing surface, or can be movably connected to the bearing surface, and no specific limitation is made here. The first mounting member 1 is also used to rotatably mount the spotlight antenna 2. The spotlight antenna 2 is rotatably mounted on the first mounting member 1 through the shell 21, so that the spotlight antenna 2 can rotate around the rotation axis of the shell 21 relative to the first mounting member 1. Among them, the rotation axis of the shell 21 is the pitch rotation axis of the spotlight antenna 2, so that the spotlight antenna 2 can be pitched relative to the first mounting member 1, so that the pitch angle of the spotlight antenna 2 can be adjusted. During installation, the first mounting member 1 is installed on the bearing surface, and the spotlight antenna 2 is rotatably mounted on the first mounting member 1. When the spotlight antenna 2 needs to be maintained, the purpose of adjusting the pitch angle of the spotlight antenna 2 is achieved through the relative rotation relationship between the spotlight antenna 2 and the first mounting member 1. In some embodiments, the installation posture of the first mounting member 1 on the bearing surface can be further adjusted so that the rotation axis of the housing 21 is roughly parallel to the horizontal plane, which is beneficial to improving the effect of adjusting the pitch angle of the spotlight antenna 2. In this embodiment, the bearing surface can be the upper plane of the building wall, or other building surfaces or non-building installation surfaces, which only need to be used to install and carry the first mounting member 1 and the spotlight antenna 2 in this embodiment so that the spotlight antenna 2 transmits signals, and no specific restrictions are made here.

[0047] A worm gear tooth profile 22 is formed on the outer wall of the shell 21, that is, the worm gear tooth profile 22 and the shell 21 are an integrally formed structure. For example, the shell 21 and the worm gear tooth profile 22 can be integrally injection molded. The integrally formed structure can improve the structural strength, and can also improve the connection reliability and stability, and can simplify the installation process of the spotlight antenna 2, and can reduce the manufacturing cost. The arc centerline of the worm gear tooth profile 22 refers to the axis at the center of the arc formed by the arrangement of multiple worm gear teeth 221. The arc centerline of the worm gear tooth profile 22 is collinear with the rotation axis of the shell 21, that is, multiple worm gear teeth 221 are arranged in an arc around the rotation axis of the shell 21 to form a worm gear structure. Since the arc centerline of the worm gear tooth profile 22 is collinear with the rotation axis of the shell 21, the worm gear tooth profile 22 can drive the spotlight antenna 2 to rotate around the rotation axis of the shell 21.

[0048] The first driving module 3 is used to drive the spotlight antenna 2 to pitch and rotate around the rotation axis of the housing 21 to achieve the pitch angle adjustment of the spotlight antenna 2. Specifically, the first driver 32 can be provided with a motor, which is connected to the first worm 31, and the first worm 31 is driven to rotate by the motor. Since the first worm 31 is meshed and connected with the worm gear 22, a worm gear mechanism is formed, so that the movement of the first worm 31 can drive the worm gear 22 to rotate around the center line of the arc, thereby driving the spotlight antenna 2 to rotate around the rotation axis of the housing 21 through the worm gear 22. Transmission through the worm gear mechanism can make the pitch angle adjustment of the spotlight antenna 2 fast and sensitive. Since the worm gear mechanism has a self-locking function, when the motor in the first driving module 3 fails, the worm gear mechanism can maintain the pitch angle of the spotlight antenna 2, thereby achieving the self-locking of the mechanism after the spotlight antenna 2 adjusts the angle, and improving the signal stability and signal coverage effect of the spotlight antenna 2.

[0049] In some embodiments, the first driver 32 may be provided with a control unit and a communication unit, and the communication unit may include a wired communication unit or a wireless communication unit; the control unit is connected to the motor and the communication unit. The first driver 32 may perform remote communication through the communication unit, and control the motor to drive the first worm 31 to rotate through the control unit. In this way, the remote electric adjustment of the pitch angle of the spotlight antenna 2 may be achieved.

[0050] When the spotlight antenna assembly 100 is installed, the spotlight antenna 2 is installed to a high altitude position through the first mounting member 1, and the pitch angle of the spotlight antenna 2 is adjusted through the first driving module 3 so that the signal coverage range of the spotlight antenna 2 meets the on-site use requirements. In this way, there is no need for manual high-altitude operations and angle adjustment, testing, confirmation and other work, which reduces the difficulty of angle adjustment of the spotlight antenna 2, especially the difficulty of high-altitude operations, and is convenient and fast, saving time and effort, and improving the debugging and installation efficiency and safety. In addition, since the mounting structure of the spotlight antenna 2 and the angle adjustment mechanism (i.e., the first driving module 3) are separated from each other, the strength of the mounting structure can be improved, the connection reliability of the spotlight antenna 2 and the first mounting member 1 can be improved, and then the stability of the spotlight antenna 2 after installation can be improved, and the signal stability and signal coverage effect of the spotlight antenna 2 can be reduced.

[0051] During the use of the spotlight antenna 2, if an external force causes the pitch angle of the spotlight antenna 2 to deviate, the pitch angle of the spotlight antenna 2 can be remotely and electrically adjusted through the first driving module 3, and the angle deviation of the spotlight antenna 2 can be corrected in time to reduce the impact on the signal stability and signal coverage of the spotlight antenna 2, which is convenient for subsequent maintenance. The pitch angle of the spotlight antenna 2 can also be remotely and electrically adjusted through the first driving module 3 during subsequent use to obtain ideal performance data of the spotlight antenna 2, which can meet the use requirements in different scenarios, thereby improving the effectiveness of the angle adjustment of the spotlight antenna 2, increasing the signal coverage range of the spotlight antenna 2, and providing a higher quality communication effect.

[0052] The spotlight antenna assembly 100 of the embodiment of the present application is used to install the spotlight antenna 2 through the first mounting member 1 and the shell 21, so that the pitch angle of the spotlight antenna 2 can be adjusted conveniently. Moreover, the worm gear tooth shape 22 and the shell 21 are an integrally formed structure, which can improve the structural strength and connection reliability, thereby improving the stability of the spotlight antenna 2 after installation and reducing costs. The first driving module 3 is used to realize the remote electric adjustment of the pitch angle of the spotlight antenna 2. The adjustment operation is simple, convenient and fast, saving time and effort, improving the debugging and installation efficiency and safety, and facilitating the adjustment of the angle of the spotlight antenna 2 during subsequent use, which is conducive to obtaining ideal performance data of the spotlight antenna 2, can meet the use requirements of different scenarios, improve the effectiveness of the angle adjustment of the spotlight antenna 2, and is conducive to expanding the signal coverage range of the spotlight antenna 2. It can provide a higher quality communication effect, improve the convenience of using the spotlight antenna assembly 100, and reduce the signal stability and signal coverage effect of the spotlight antenna 2. By adopting a worm gear mechanism for transmission, the pitch angle of the spotlight antenna 2 can be adjusted quickly and sensitively, and the mechanism self-locking can be achieved after the spotlight antenna 2 adjusts the angle, thereby improving the signal stability and signal coverage effect of the spotlight antenna 2.

[0053] In some embodiments, the arc angle of the worm gear tooth profile 22 is greater than or equal to 90 degrees.

[0054] The arc angle of the worm gear tooth profile 22 refers to the central angle of the arc formed by the arrangement of multiple worm gear teeth 221, that is, the angle between the two worm gear teeth 221 at both ends of the worm gear tooth profile 22 and the perpendicular line of the rotation axis of the housing 21. Since the first worm 31 drives the spotlight antenna 2 to pitch and rotate through the worm gear tooth profile 22, the arc angle range of the worm gear tooth profile 22 limits the pitch angle adjustment range of the spotlight antenna 2. For example, the spotlight antenna 2 can achieve a pitch angle adjustment range of ±45 degrees.

[0055] By setting the arc angle of the worm gear tooth shape 22 to be greater than or equal to 90 degrees, the spotlight antenna 2 can achieve a pitch angle adjustment within a range of 90 degrees, thereby increasing the signal coverage range of the spotlight antenna 2, improving the signal coverage effect, and meeting actual use requirements.

[0056] In some embodiments, see Figure 1 , Figure 2 and Figure 4 , Figure 4 The schematic diagram of the structure of the first mounting member 1 in some embodiments of the present application is shown, and the first mounting member 1 includes a base 11 and a support portion 12 connected to the base 11. The housing 21 is rotatably connected to an end of the support portion 12 away from the base 11, and the worm gear 22 is provided on the outer wall of the housing 21 close to the base 11. The first driving module 3 is provided on the base 11 and is located between the housing 21 and the base 11.

[0057] The base 11 may be a plate-like structure, such as a rectangular plate, a circular plate, etc.; the base 11 may also be other structures, such as a block, etc. The support portion 12 may also be a plate-like structure, such as a strip plate. The support portion 12 may also be other structures, such as a rod, etc. The rotation axis of the housing 21 may be perpendicular to the extension direction of the support portion 12 away from the base 11. Parallel to the surface of the base 11 facing the housing 21.

[0058] By arranging the worm gear tooth shape 22 on the outer wall of the housing 21 close to the base 11, and arranging the first driving module 3 between the housing 21 and the base 11, the driving mechanism for driving the spotlight antenna 2 to rotate and the rotation axis of the spotlight antenna 2 are arranged at intervals from each other, which can reduce the driving torque for driving the spotlight antenna 2 to rotate, and drive the spotlight antenna 2 to pitch and rotate more labor-saving, and the pitch angle adjustment is faster and more sensitive. At the same time, the worm gear mechanism at this time can play the role of supporting the spotlight antenna 2, and can improve the connection strength between the spotlight antenna 2 and the first mounting member 1, thereby improving the stability of the spotlight antenna 2 after installation, and improving the signal stability and signal coverage effect of the spotlight antenna 2. In addition, the space occupied by the worm gear tooth shape 22 and the first driving module 3 can be reduced, the structure is more compact, and it is conducive to reducing the volume of the spotlight antenna assembly 100.

[0059] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The base 11 has a mounting surface 111 facing the worm gear tooth shape 22, and the first driving module 3 is mounted on the mounting surface 111. The first worm 31 is arranged obliquely relative to the mounting surface 111.

[0060] The first worm 31 is tilted relative to the mounting surface 111 , which means that one end of the first worm 31 is disposed close to the mounting surface 111 of the base 11 , and the other end of the first worm 31 is tilted and extended in a direction away from the mounting surface 111 .

[0061] By tilting the first worm gear 31 relative to the mounting surface 111, one end of the first worm gear 31 can be set in the gap between the shell 21 and the base 11. At the same time, the tilted and extended first worm gear 31 can be adapted to the arc structure formed by the worm gear tooth shape 22, which can reduce interference and is conducive to achieving a wide range of pitch angle adjustment. It also saves space and has a more compact structure, which is conducive to reducing the volume of the spotlight antenna assembly 100.

[0062] In some embodiments, see Figure 5 , Figure 5 The schematic diagram of the structure of the first driving module 3 in some embodiments of the present application is shown, and the first driving module 3 also includes a mounting plate 33 and a first support 34. The mounting plate 33 may include a connecting plate and an inclined plate, and the inclined plate is fixedly connected to the connecting plate, for example, the inclined plate and the connecting plate may be integrally formed; the inclined plate is inclined relative to the connecting plate, for example, the angle between the inclined plate and the connecting plate is between 30° and 60°. The first support 34 is fixedly connected to the inclined plate of the mounting plate 33. The first driver 32 is mounted on the inclined plate of the mounting plate 33, one end of the first driver 32 is connected to the first worm 31, and the other end of the first worm 31 is inserted into the first support 34. When the mounting plate 33 is fixed to the mounting surface 111 of the base 11 through the connecting plate, the tilting plate is tilted relative to the mounting surface 111 of the base 11, thereby tilting the first worm 31 relative to the mounting surface 111; at this time, the first worm 31 and the worm gear tooth profile 22 are in a meshing state. At this time, the motor is controlled by the controller to drive the first worm 31 to drive the worm gear tooth profile 22 to rotate, thereby adjusting the pitch angle of the spotlight antenna 2.

[0063] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The first mounting member 1 includes two supporting portions 12 , and the two supporting portions 12 are arranged at an interval. The housing 21 is rotatably connected between the two supporting portions 12 .

[0064] The support portion 12 may be disposed perpendicular to the mounting surface 111 of the base 11. Figure 3 As shown, the housing 21 is provided with rotation connection parts 211 on opposite sides along the extension direction of the rotation axis of the housing 21; for example, the rotation connection parts 211 may be convex shafts protruding from the two sides of the housing 21. Figure 4 As shown, the support portion 12 is provided with a corresponding rotation connection hole 121. The rotation connection portion 211 is inserted into the rotation connection hole 121, so that the housing 21 is rotatably connected to the support portion 12, and then the housing 21 is rotatably connected between the two support portions 12. Figure 1 and Figure 2 As shown, the spotlight antenna assembly 100 may further include a locking accessory 4 , for example, the locking accessory 4 may be a retaining ring, and the locking accessory 4 is disposed at the rotating connection hole 121 , and the locking accessory 4 prevents the rotating connection part 211 from slipping out of the rotating connection hole 121 .

[0065] The spotlight antenna 2 is rotatably supported on the first mounting member 1 by two supporting parts 12, so that the connection reliability is improved. The stability of the spotlight antenna 2 after installation is higher, and the signal stability and signal coverage effect of the spotlight antenna 2 can be improved.

[0066] In some embodiments, see Figure 1 , Figure 2 , Figure 6 and Figure 7 , Figure 6 shows a schematic structural diagram of a spotlight antenna assembly in some embodiments of the present application without the spotlight antenna and the first driving module, Figure 7 Another perspective structural schematic diagram of the spotlight antenna assembly in some embodiments of the present application without the spotlight antenna is shown. The spotlight antenna assembly 100 also includes a second mounting member 5, a first transmission member 60, and a second driving module 6. The second mounting member 5 includes a mounting portion 51 and a fixed connection portion 52 connected to the mounting portion 51. The first mounting member 1 is rotatably connected to the mounting portion 51, and the rotation axis of the first mounting member 1 is perpendicular to the rotation axis of the housing 21. The first transmission member 60 is connected to the first mounting member 1, and the rotation axis of the first transmission member 60 is colinear with the rotation axis of the first mounting member 1. The second driving module 6 is arranged on the mounting portion 51, and the second driving module 6 includes a second transmission member 61 and a second driver 62. The second transmission member 61 is meshed and connected with the first transmission member 60. The second driver 62 is connected to the second transmission member 61 and is used to drive the second transmission member 61 to move. The second transmission member 61 can drive the first mounting member 1 to rotate through the first transmission member 60.

[0067] The second mounting member 5 is used to mount and fix the spotlight antenna assembly 100 as a whole. The fixed connection portion 52 can be used to be fixedly connected to an external mounting structure to mount the spotlight antenna assembly 100 as a whole on the external mounting structure. The connection method between the fixed connection portion 52 and the external mounting structure can be, but is not limited to, fastening connection, clamping or bonding, etc. For example, the fixed connection portion 52 can be provided with a connection hole, and a fastener such as a bolt is passed through the connection hole to fasten the fixed connection portion 52 to the external mounting structure.

[0068] The first mounting member 1 is rotatably connected to the second mounting member 5, so that the first mounting member 1 can drive the mounted spotlight antenna 2 to rotate around the rotation axis of the first mounting member 1. The rotation axis of the first mounting member 1 is parallel to the azimuth rotation axis of the spotlight antenna 2, so that the spotlight antenna 2 can be rotated in azimuth relative to the second mounting member 5, thereby adjusting the horizontal azimuth angle of the spotlight antenna 2.

[0069] At this time, the first mounting member 1 and the second mounting member 5 together form a mounting structure of the spotlight antenna 2, which can conveniently adjust the elevation angle and horizontal azimuth angle of the spotlight antenna 2 at the same time.

[0070] The second driving module 6 is used to drive the spotlight antenna 2 to rotate in azimuth around the rotation axis of the first mounting member 1, so as to achieve horizontal azimuth adjustment of the spotlight antenna 2. Specifically, the second driver 62 may also be provided with a motor, which is connected to the second transmission member 61, and the second transmission member 61 is driven to move by the motor. Since the second transmission member 61 is meshedly connected with the first transmission member 60, and the first transmission member 60 is connected to the first mounting member 1, the movement of the second transmission member 61 can drive the movement of the first transmission member 60, and the first transmission member 60 drives the first mounting member 1 to rotate, thereby driving the spotlight antenna 2 to rotate around the rotation axis of the first mounting member 1. The movement of the second transmission member 61 may be rotation or linear translation. For example, the second transmission member 61 may be a rack, etc., which is not limited here.

[0071] In some embodiments, the second driver 62 may also be provided with a control unit and a communication unit, and the communication unit may include a wired communication unit or a wireless communication unit; the control unit is connected to the motor and the communication unit. The second driver 62 may perform remote communication through the communication unit, and control the motor to drive the second transmission member 61 to move through the control unit. In this way, the horizontal azimuth angle of the spotlight antenna 2 may be remotely electrically adjusted.

[0072] When the spotlight antenna assembly 100 is installed, the spotlight antenna 2 is installed to a high altitude position through the first mounting member 1 and the second mounting member 5, the pitch angle of the spotlight antenna 2 is adjusted through the first driving module 3, and the horizontal azimuth angle of the spotlight antenna 2 is adjusted through the second driving module 6, so that the signal coverage range of the spotlight antenna 2 meets the use requirements on site. In this way, there is no need for manual high-altitude operations and angle adjustment, testing, confirmation and other work, which reduces the difficulty of angle adjustment of the spotlight antenna 2, especially the difficulty of high-altitude operations, is convenient and fast, saves time and effort, and improves the debugging and installation efficiency and safety. In addition, since the mounting structure of the spotlight antenna 2 and the angle adjustment mechanism (i.e., the first driving module 3 and the second driving module 6) are separated from each other, the strength of the mounting structure can be improved, and the connection reliability between the spotlight antenna 2 and the first mounting member 1 and the first mounting member 1 and the second mounting member 5 can be improved, thereby improving the stability of the spotlight antenna 2 after installation, and reducing the signal stability and signal coverage effect that affect the spotlight antenna 2.

[0073] During the use of the spotlight antenna 2, if an external force causes the installation angle of the spotlight antenna 2 to shift, the first drive module 3 and the second drive module 6 can be used to remotely and electrically adjust the pitch angle and horizontal azimuth angle of the spotlight antenna 2, and the angle deviation of the spotlight antenna 2 can be corrected in time to reduce the impact on the signal stability and signal coverage of the spotlight antenna 2, and facilitate subsequent maintenance. In the subsequent use process, the pitch angle and horizontal azimuth angle of the spotlight antenna 2 can also be remotely and electrically adjusted through the first drive module 3 and the second drive module 6 to obtain ideal performance data of the spotlight antenna 2, which can meet the use requirements in different scenarios, thereby improving the effectiveness of the angle adjustment of the spotlight antenna 2, increasing the signal coverage range of the spotlight antenna 2, and providing a higher quality communication effect.

[0074] The spotlight antenna 2 is installed by the first mounting member 1 and the second mounting member 5, so that the pitch angle and the horizontal azimuth angle of the spotlight antenna 2 can be adjusted conveniently, and the strength of the mounting structure and the connection reliability can be improved, thereby improving the stability of the spotlight antenna 2 after installation. The pitch angle and the horizontal azimuth angle of the spotlight antenna 2 can be remotely and electrically adjusted by the first driving module 3 and the second driving module 6. The adjustment operation is simple, convenient and fast, saving time and effort, improving the efficiency and safety of debugging and installation, and facilitating the adjustment of the angle of the spotlight antenna 2 during subsequent use, which is conducive to obtaining ideal performance data of the spotlight antenna 2, can meet the use requirements of different scenarios, improve the effectiveness of the angle adjustment of the spotlight antenna 2, and is conducive to expanding the signal coverage range of the spotlight antenna 2. It can provide a higher quality communication effect, improve the convenience of using the spotlight antenna assembly 100, and reduce the impact on the signal stability and signal coverage effect of the spotlight antenna 2.

[0075] In some embodiments, see Figure 7The base 11 is rotatably connected to the second mounting member 5, and the support portion 12 is connected to a side of the base 11 away from the second mounting member 5. In some embodiments, the two support portions 12 are spaced apart in a direction perpendicular to the rotation axis of the first mounting member 1.

[0076] In some embodiments, see Figure 7 The second driving module 6 is disposed on a side of the mounting portion 51 away from the first mounting member 1 .

[0077] The first driving module 3 is arranged on the side of the first mounting member 1 away from the mounting portion 51. In this way, the interference between the second driving module 6 and the first driving module 3 can be reduced, the space occupied by the second driving module 6 can be saved, the structure is more compact, the volume of the second mounting member 5 can be reduced, and the cost can be reduced.

[0078] In some embodiments, see Figure 7 , the second driving module 6 also includes a second support 63. The second driver 62 and the second support 63 are installed on the side of the mounting portion 51 away from the first mounting member 1, one end of the second driver 62 is connected to the second transmission member 61, and the other end of the second transmission member 61 is connected to the second support 63. At this time, the second transmission member 61 is in a meshing state with the first transmission member 60.

[0079] In some embodiments, the first mounting member 1 and the second mounting member 5 are connected to each other rotatably via a rotating shaft 7. Figure 4 The base 11 of the first mounting member 1 is provided with an axial hole 112, and the axial hole 112 is in the shape of a non-rotating body, for example, the shape of the axial hole 112 can be square, triangular, etc. Figure 8 , Figure 8 The schematic diagram of the structure of the rotating shaft 7 in some embodiments of the present application is shown. The spotlight antenna assembly 100 also includes the rotating shaft 7. The rotating shaft 7 includes a rod portion 71, a head portion 72 connected to one end of the rod portion 71, and a connecting section 75 connected to the other end of the rod portion 71. The rotating shaft 7 also includes a first anti-rotation portion 73 arranged between the rod portion 71 and the head portion 72. The cross-sectional shape of the first anti-rotation portion 73 is adapted to the shape of the shaft hole 112. For example, the cross-sectional shape of the first anti-rotation portion 73 can be square. The outer diameter of the head portion 72 is larger than the outer diameter of the shaft hole 112. Figure 6 As shown, the rod portion 71 of the rotating shaft 7 passes through the shaft hole 112, the first anti-rotation portion 73 is matched and nested with the shaft hole 112, and the head 72 is stopped on the base 11, so that the rotating shaft 7 is connected to the first mounting member 1, and the first anti-rotation portion 73 is matched with the shaft hole 112 to prevent the first mounting member 1 and the rotating shaft 7 from rotating relative to each other, so that the rotation of the rotating shaft 7 can drive the first mounting member 1 to rotate. In some embodiments, the head 72 can be flat, which can reduce the portion of the head 72 protruding from the base 11 and reduce interference.

[0080] Combination Figure 7 and Figure 8 As shown, the rotating shaft 7 also includes a second anti-rotation portion 74 provided on the rod portion 71, the rod portion 71 of the rotating shaft 7 passes through the second mounting member 5, the first transmission member 60 is sleeved on the rod portion 71 and connected to the second anti-rotation portion 74, the locking nut 70 is connected to the connecting section 75 and locks the first transmission member 60 on the rotating shaft 7, so that the first transmission member 60 is not easy to escape, thereby connecting the first transmission member 60 to the rotating shaft 7. The second anti-rotation portion 74 prevents the first transmission member 60 from rotating relative to the rotating shaft 7, so that the rotation of the first transmission member 60 can drive the rotating shaft 7 to rotate. At the same time, the first transmission member 60 limits the rotating shaft 7 from being separated from the second mounting member 5, so that the first mounting member 1 and the second mounting member 5 can be connected to each other in a relatively rotatable manner. The second driver 62 drives the second worm 611 to move, the second worm 611 drives the first transmission member 60 to rotate, the first transmission member 60 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the first mounting member 1 to rotate relative to the second mounting member 5, thereby adjusting the horizontal azimuth angle of the spotlight antenna 2.

[0081] In some embodiments, see Figure 7 The first transmission member 60 includes a worm wheel 601 , and the second transmission member 61 includes a second worm 611 , and the second worm 611 is meshedly connected with the worm wheel 601 .

[0082] The central axis of the worm wheel 601 of the first transmission member 60 is colinear with the rotation axis of the first mounting member 1. The second worm 611 is meshedly connected with the worm wheel 601 to form a worm gear mechanism. Transmission through the worm gear mechanism can make the horizontal azimuth angle adjustment of the spotlight antenna 2 fast and sensitive. Since the worm gear mechanism has a self-locking function, when the motor in the second drive module 6 fails, the worm gear mechanism can maintain the horizontal azimuth angle of the spotlight antenna 2. In this way, the self-locking of the mechanism after the spotlight antenna 2 adjusts the angle can be achieved, which can improve the signal stability and signal coverage effect of the spotlight antenna 2.

[0083] In some embodiments, see Figure 6 and Figure 7 The spotlight antenna assembly 100 further includes a first stopper 8, which is connected to one of the first mounting member 1 and the mounting portion 51. A first stopper 80 is provided on the other of the first mounting member 1 and the mounting portion 51, and the first stopper 80 is in an arc shape, and the arc center line of the first stopper 80 is colinear with the rotation axis of the first mounting member 1. The first stopper 8 is connected to the first stopper 80, and the first stopper 8 is configured to move along the first stopper 80.

[0084] The first limiting portion 80 may be a circular arc groove or a circular arc through hole. The first limiting portion 80 may also be other circular arc structures. The first limiting portion 80 is provided on the first mounting member 1 or the second mounting member 5, and the first mounting member 1 and the second mounting member 5 are movably connected together through the first limiting member 8, so that the first limiting member 8 moves along the first limiting portion 80 without falling out. For example, the first limiting portion 80 may be a circular arc groove, and the first limiting member 8 is limited to slide in the circular arc groove without falling out. In some embodiments, combined with Figure 4 and Figure 6 A first connection hole 113 is formed on the base 11 of the first mounting member 1, and the first stopper 8 is connected to the first mounting member 1 through the first connection hole 113. Figure 6 and Figure 7 The first limiting portion 80 is an arc-shaped through hole opened on the mounting portion 51 of the second mounting member 5. The first limiting member 8 has a limiting rod and blocking pieces connected to both ends of the limiting rod. The limiting rod is passed through the first connecting hole 113 and the arc-shaped through hole. The blocking pieces at both ends of the limiting rod are respectively stopped on the base 11 and the mounting portion 51, so that the first limiting member 8 can slide along the arc-shaped through hole without falling out.

[0085] In this way, the first limiting member 8 cooperates with the first limiting portion 80 to limit the relative rotation of the first mounting member 1 and the second mounting member 5, thereby improving the stability of the relative rotation of the first mounting member 1 and the second mounting member 5, which is beneficial to improving the stability of the rotation of the spotlight antenna 2 around the azimuth axis.

[0086] In some embodiments, see Figure 6 and Figure 7 The spotlight antenna assembly 100 further includes a second stopper 9, which is connected to one of the first mounting member 1 and the mounting portion 51. A second stopper 90 is further provided on the other of the first mounting member 1 and the mounting portion 51, and the second stopper 90 is in an arc shape, and the arc centerline of the second stopper 90 is collinear with the arc centerline of the first stopper 80. The second stopper 9 is connected to the second stopper 90, and the second stopper 9 is configured to move along the second stopper 90. The arc radius of the first stopper 80 is different from the arc radius of the second stopper 90.

[0087] The second limiting portion 90 may be a circular arc-shaped slot or a circular arc-shaped through hole. The second limiting portion 90 may also have other circular arc-shaped structures. Figure 4 and Figure 6 The base 11 of the first mounting member 1 is provided with a second connection hole 114, and the second stopper 9 is connected to the first mounting member 1 through the second connection hole 114. Figure 6 and Figure 7The second limiting portion 90 is an arc-shaped through hole opened on the mounting portion 51 of the second mounting member 5. The second limiting member 9 has a limiting rod and blocking pieces connected to both ends of the limiting rod. The limiting rod is penetrated through the second connecting hole 114 and the arc-shaped through hole. The blocking pieces at both ends of the limiting rod are respectively stopped on the base 11 and the mounting portion 51, so that the second limiting member 9 can slide along the arc-shaped through hole without falling out.

[0088] By providing two limiting structures of different sizes, the relative rotation between the first mounting member 1 and the second mounting member 5 can be limited at different radial positions, and mutual interference can be reduced, thereby further improving the stability of the relative rotation between the first mounting member 1 and the second mounting member 5.

[0089] In some embodiments, see Figure 6 and Figure 7 The first limiting portion 80 and the second limiting portion 90 are arranged on opposite sides of the rotation axis of the first mounting member 1 .

[0090] The first limiting portion 80 and the second limiting portion 90 are arranged opposite to each other. In this way, the two limiting structures are arranged opposite to each other, which can further improve the stability.

[0091] In some embodiments, the arc angle of the first limiting portion 80 is greater than or equal to 180 degrees, and the arc angle of the second limiting portion 90 is greater than or equal to 180 degrees.

[0092] That is, the first limit portion 80 and the second limit portion 90 are both major arcs, that is, greater than 180 degrees. In this way, the spotlight antenna assembly 100 can achieve horizontal azimuth adjustment of plus or minus 180 degrees, increase the angle adjustment range, and improve the signal coverage effect of the spotlight antenna 2.

[0093] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0094] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
