[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0043] It should be noted that an element is referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] When installing, maintaining, and optimizing networks, spotlight antennas require adjustments to their elevation and azimuth angles to ensure a more stable signal and better coverage. The elevation angle is the angle between the antenna's maximum radiation direction and the horizontal plane. For example, the elevation angle is 0 degrees when the antenna's maximum radiation direction is parallel to the horizontal plane. The azimuth angle is the angle by which the antenna's maximum radiation direction deflects around an axis perpendicular to the horizontal plane. For example, using the antenna's maximum radiation direction pointing due north as a standard, adjusting the antenna's direction slightly east or west by an angle is the azimuth angle. Therefore, the azimuth angle is 0 degrees when the antenna's maximum radiation direction is due north.

[0045] See Figures 1 to 3 , Figure 1 This paper shows one of the structural schematic diagrams of a spotlight antenna assembly in some embodiments of this application. Figure 2 The second schematic diagram shows the structure of a spotlight antenna assembly in some embodiments of this application. Figure 3The diagram shows a schematic of the structure of a spotlight antenna in some embodiments of this application. The spotlight antenna assembly 100 provided in this application includes a first mounting component 1, a spotlight antenna 2, and a first driving module 3. The first mounting component 1 is used to mount on a bearing surface. The spotlight antenna 2 includes a housing 21 and a worm gear tooth profile 22 formed on the outer wall of the housing 21. The housing 21 is rotatably connected to the first mounting component 1. The worm gear tooth profile 22 includes a plurality of worm gear teeth 221 arranged in an arc, and the center line of the arc of the worm gear tooth profile 22 is collinear with the rotation axis of the housing 21. The first driving module 3 is disposed on the first mounting component 1. The first driving module 3 includes a first worm 31 and a first driver 32. The first worm 31 is meshed with the worm gear tooth 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 around the rotation axis of the housing 21 through the worm gear tooth profile 22.

[0046] The first mounting component 1 is used for mounting on the bearing surface. The first mounting component 1 can be fixedly connected to the bearing surface or movably connected to it; no specific limitation is made here. The first mounting component 1 is also used for rotatably mounting the spotlight antenna 2. The spotlight antenna 2 is rotatably mounted on the first mounting component 1 via the housing 21, allowing the spotlight antenna 2 to rotate relative to the first mounting component 1 about the rotation axis of the housing 21. The rotation axis of the housing 21 is the pitch rotation axis of the spotlight antenna 2, allowing the spotlight antenna 2 to perform pitch rotation relative to the first mounting component 1, thereby allowing adjustment of the pitch angle of the spotlight antenna 2. During installation, the first mounting component 1 is mounted on the bearing surface, and the spotlight antenna 2 is rotatably mounted on the first mounting component 1. When maintenance of the spotlight antenna 2 is required, the pitch angle of the spotlight antenna 2 can be adjusted through the relative rotational relationship between the spotlight antenna 2 and the first mounting component 1. In some embodiments, the mounting 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 approximately parallel to the horizontal plane, which is beneficial to improving the adjustment effect of the elevation 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 mounting surfaces, as long as it is used to install and support the first mounting member 1 and the spotlight antenna 2 in this embodiment so that the spotlight antenna 2 can transmit signals, and no specific limitations are made here.

[0047] A worm gear tooth profile 22 is formed on the outer wall of the housing 21, meaning that the worm gear tooth profile 22 and the housing 21 are integrally molded. For example, the housing 21 and the worm gear tooth profile 22 can be integrally injection molded. This integral molding structure improves structural strength, connection reliability and stability, simplifies the installation process of the spotlight antenna 2, and reduces manufacturing costs. 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 housing 21, meaning that multiple worm gear teeth 221 are arranged in an arc around the rotation axis of the housing 21 to form a worm gear structure. Because the arc centerline of the worm gear tooth profile 22 is collinear with the rotation axis of the housing 21, the worm gear tooth profile 22 can drive the spotlight antenna 2 to rotate around the rotation axis of the housing 21.

[0048] The first drive module 3 is used to drive the spotlight antenna 2 to rotate in pitch around the rotation axis of the housing 21, thereby adjusting the pitch angle of the spotlight antenna 2. Specifically, the first driver 32 may be equipped with a motor, which is connected to the first worm gear 31, driving the first worm gear 31 to rotate. Since the first worm gear 31 meshes with the worm wheel tooth 22, forming a worm gear mechanism, the movement of the first worm gear 31 can drive the worm wheel tooth 22 to rotate around the arc centerline, thereby driving the spotlight antenna 2 to rotate around the rotation axis of the housing 21. Through the transmission of the worm gear mechanism, the pitch angle adjustment of the spotlight antenna 2 can be fast and sensitive. Since the worm gear mechanism has a self-locking function, when the motor in the first drive module 3 fails, the worm gear mechanism can maintain the pitch angle of the spotlight antenna 2, thereby achieving mechanism self-locking after the spotlight antenna 2 has adjusted its angle, improving the signal stability and signal coverage of the spotlight antenna 2.

[0049] In some embodiments, the first driver 32 may be equipped with a control unit and a communication unit, the communication unit including 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 can communicate remotely through the communication unit and control the motor to drive the first worm gear 31 to rotate through the control unit. In this way, remote electric adjustment of the elevation angle of the spotlight antenna 2 can be realized.

[0050] During installation of the spotlight antenna assembly 100, the spotlight antenna 2 is mounted to a high position using the first mounting component 1. The elevation angle of the spotlight antenna 2 is adjusted using the first drive module 3 to ensure that the signal coverage of the spotlight antenna 2 meets the on-site usage requirements. This eliminates the need for manual high-altitude work and angle adjustment, testing, and verification, reducing the difficulty of adjusting the angle of the spotlight antenna 2, especially high-altitude work. It is convenient, quick, time-saving, and labor-saving, improving debugging and installation efficiency and safety. Furthermore, because the mounting structure of the spotlight antenna 2 is separate from the angle adjustment mechanism (i.e., the first drive module 3), the strength of the mounting structure can be increased, improving the connection reliability between the spotlight antenna 2 and the first mounting component 1. This, in turn, improves the stability of the spotlight antenna 2 after installation, reducing the impact on the signal stability and signal coverage effect of the spotlight antenna 2.

[0051] If the elevation angle of the spotlight antenna 2 shifts due to external forces during use, the elevation angle can be remotely and electrically adjusted via the first drive module 3 to correct the angular shift in a timely manner, reducing the impact on signal stability and coverage, and facilitating subsequent maintenance. Furthermore, the elevation angle can be remotely and electrically adjusted via the first drive module 3 to obtain ideal performance data, meeting the needs of different scenarios, thereby improving the effectiveness of angle adjustment, increasing signal coverage, and providing higher quality communication.

[0052] The spotlight antenna assembly 100 of this application embodiment mounts the spotlight antenna 2 via the first mounting component 1 and the housing 21, facilitating the adjustment of the elevation angle of the spotlight antenna 2. Furthermore, the worm gear tooth 22 and the housing 21 are integrally formed, improving structural strength and connection reliability, thereby enhancing the stability of the spotlight antenna 2 after installation and reducing costs. The first drive module 3 enables remote electric adjustment of the elevation angle of the spotlight antenna 2. This adjustment is simple, convenient, quick, and time-saving, improving debugging and installation efficiency and safety. It also facilitates subsequent adjustment of the spotlight antenna 2's angle during use, helping to obtain ideal performance data for the spotlight antenna 2, meeting the needs of different scenarios, improving the effectiveness of the spotlight antenna 2's angle adjustment, expanding the signal coverage range of the spotlight antenna 2, providing higher quality communication, improving the ease of use of the spotlight antenna assembly 100, and reducing the impact on the signal stability and signal coverage of the spotlight antenna 2. By using a worm gear mechanism for transmission, the elevation angle of the spotlight antenna 2 can be adjusted quickly and sensitively, and the mechanism can be self-locked after the spotlight antenna 2 is adjusted, thereby improving the signal stability and signal coverage 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 perpendicular lines from the two worm gear teeth 221 located at both ends of the worm gear tooth profile 22 to the rotation axis of the housing 21. Since the first worm 31 drives the spotlight antenna 2 to rotate in pitch through the worm gear tooth profile 22, the range of the arc angle 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 profile 22 to be greater than or equal to 90 degrees, the spotlight antenna 2 can achieve pitch angle adjustment within a 90-degree range, which can increase the signal coverage range of the spotlight antenna 2, improve the signal coverage effect, and meet the actual use requirements.

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

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

[0058] By placing the worm gear tooth 22 on the outer wall of the housing 21 near the base 11, and placing the first drive module 3 between the housing 21 and the base 11, the drive mechanism for driving the spotlight antenna 2 to rotate is spaced apart from the rotation axis of the spotlight antenna 2. This reduces the driving torque required to drive the spotlight antenna 2 to rotate, making pitch rotation easier and pitch angle adjustment faster and more sensitive. Simultaneously, the worm gear mechanism can support the spotlight antenna 2, improving the connection strength between the spotlight antenna 2 and the first mounting component 1, thereby enhancing the stability of the spotlight antenna 2 after installation and improving its signal stability and coverage. Furthermore, it reduces the space occupied by the worm gear tooth 22 and the first drive module 3, resulting in a more compact structure and reducing the overall size 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 profile 22, and the first drive module 3 is mounted on the mounting surface 111. The first worm 31 is inclined relative to the mounting surface 111.

[0060] The first worm 31 is inclined relative to the mounting surface 111, meaning that one end of the first worm 31 is close to the mounting surface 111 of the base 11, and the other end of the first worm 31 extends inclined 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 placed in the gap between the housing 21 and the base 11. At the same time, the tilted first worm gear 31 can be adapted to the arc-shaped structure formed by the worm gear tooth profile 22, which can reduce interference, facilitate a wide range of pitch angle adjustment, save space, make the structure more compact, and help reduce the volume of the spotlight antenna assembly 100.

[0062] In some embodiments, see Figure 5 , Figure 5 A schematic diagram of the structure of the first drive module 3 in some embodiments of this application is shown. The first drive module 3 further includes a mounting plate 33 and a first support 34. The mounting plate 33 may include a connecting plate and an inclined plate. 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 included 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 gear 31, and the other end of the first worm gear 31 is inserted into the first support 34. When the mounting plate 33 is fixed to the mounting surface 111 of the base 11 via 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 22 are in a meshing state. At this time, the controller controls the motor to drive the first worm 31 to drive the worm gear tooth 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 component 1 includes two support portions 12, which are spaced apart. The housing 21 is rotatably connected between the two support portions 12.

[0064] The support portion 12 can be disposed perpendicular to the mounting surface 111 of the base 11. In some embodiments, combined with Figure 3 As shown, the housing 21 has rotating connecting portions 211 on opposite sides extending along the rotation axis of the housing 21; for example, the rotating connecting portions 211 can be protruding shafts on both sides of the housing 21. Figure 4 As shown, a rotatable connecting hole 121 is provided on the support part 12. A rotatable connecting part 211 passes through the rotatable connecting hole 121, thereby rotatably connecting the housing 21 to the support part 12, and further rotatably connecting the housing 21 between the two support parts 12. Figure 1 and Figure 2 As shown, the spotlight antenna assembly 100 may also include a locking accessory 4, for example, the locking accessory 4 may be a retaining ring. The locking accessory 4 is provided at the rotating connection hole 121, and the locking accessory 4 prevents the rotating connection part 211 from coming out of the rotating connection hole 121.

[0065] The spotlight antenna 2 is rotatably supported on the first mounting part 1 by two support parts 12, which improves the connection reliability and makes the spotlight antenna 2 more stable after installation, thus improving the signal stability and signal coverage of the spotlight antenna 2.

[0066] In some embodiments, see Figure 1 , Figure 2 , Figure 6 and Figure 7 , Figure 6 This paper shows a schematic diagram of the structure of a spotlight antenna assembly in some embodiments of the present application, omitting the spotlight antenna and the first driving module. Figure 7 This diagram illustrates a spotlight antenna assembly omitting the spotlight antenna in some embodiments of this application. The spotlight antenna assembly 100 further includes a second mounting member 5, a first transmission member 60, and a second drive 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 collinear with the rotation axis of the first mounting member 1. The second drive module 6 is disposed on the mounting portion 51. The second drive module 6 includes a second transmission member 61 and a second driver 62. The second transmission member 61 is engaged with the first transmission member 60, and 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 component 5 is used for the overall installation and fixation of the spotlight antenna assembly 100. The fixing connection part 52 can be used for fixed connection with the external mounting structure to install the spotlight antenna assembly 100 as a whole onto the external mounting structure. The connection method between the fixing connection part 52 and the external mounting structure can be, but is not limited to, fastening, snap-fitting, or adhesive bonding. For example, the fixing connection part 52 can be provided with a connection hole, and fasteners such as bolts can be inserted through the connection hole to fasten the fixing connection part 52 to the external mounting structure.

[0068] The first mounting component 1 is rotatably connected to the second mounting component 5, allowing the first mounting component 1 to drive the mounted spotlight antenna 2 to rotate around the rotation axis of the first mounting component 1. The rotation axis of the first mounting component 1 is parallel to the azimuth rotation axis of the spotlight antenna 2, enabling the spotlight antenna 2 to perform azimuth deflection relative to the second mounting component 5, thereby allowing adjustment of the horizontal azimuth angle of the spotlight antenna 2.

[0069] At this time, the first mounting component 1 and the second mounting component 5 together form the 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 drive module 6 is used to drive the spotlight antenna 2 to rotate around the rotation axis of the first mounting member 1, thereby adjusting the horizontal azimuth angle of the spotlight antenna 2. Specifically, the second driver 62 may also be equipped with a motor, which is connected to the second transmission member 61, driving the second transmission member 61 to move. Since the second transmission member 61 is meshed 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 first transmission member 60 to move, and the first transmission member 60 drives the first mounting member 1 to rotate, thereby causing the spotlight antenna 2 to rotate around the rotation axis of the first mounting member 1. The movement of the second transmission member 61 can be rotational or linear translational; for example, the second transmission member 61 can be a rack, etc., and there is no limitation here.

[0071] In some embodiments, the second driver 62 may also include a control unit and a communication unit, the communication unit including 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 can communicate remotely via the communication unit and control the motor to drive the second transmission member 61 to move via the control unit. In this way, remote electric adjustment of the horizontal azimuth angle of the spotlight antenna 2 can be realized.

[0072] During installation of the spotlight antenna assembly 100, the spotlight antenna 2 is mounted to a high position using the first mounting component 1 and the second mounting component 5. The elevation angle of the spotlight antenna 2 is adjusted by the first drive module 3, and the horizontal azimuth angle is adjusted by the second drive module 6, ensuring that the signal coverage of the spotlight antenna 2 meets the on-site usage requirements. This eliminates the need for manual high-altitude work and angle adjustment, testing, and verification, reducing the difficulty of adjusting the angle of the spotlight antenna 2, especially high-altitude work. It is convenient, quick, time-saving, and labor-saving, improving debugging and installation efficiency and safety. Furthermore, because the mounting structure of the spotlight antenna 2 is separate from the angle adjustment mechanism (i.e., the first drive module 3 and the second drive module 6), the strength of the mounting structure can be increased. This improves the reliability of the connection between the spotlight antenna 2 and the first mounting component 1, and between the first mounting component 1 and the second mounting component 5, thereby improving the stability of the spotlight antenna 2 after installation and reducing the impact on the signal stability and signal coverage effect of the spotlight antenna 2.

[0073] If the installation angle of the spotlight antenna 2 shifts due to external forces during use, the elevation and azimuth angles can be remotely and electrically adjusted via the first drive module 3 and the second drive module 6 to correct the angular shift in a timely manner, reducing the impact on signal stability and coverage, and facilitating subsequent maintenance. Furthermore, the elevation and azimuth angles can be remotely and electrically adjusted via the first drive module 3 and the second drive module 6 to obtain ideal performance data for the spotlight antenna 2, meeting the needs of different scenarios, thereby improving the effectiveness of angle adjustment, increasing signal coverage, and providing higher quality communication.

[0074] The spotlight antenna 2 is installed using the first mounting component 1 and the second mounting component 5, facilitating the adjustment of its elevation and azimuth angles. This also improves the strength and reliability of the installation structure, thereby enhancing the stability of the spotlight antenna 2 after installation. The first drive module 3 and the second drive module 6 enable remote electric adjustment of the elevation and azimuth angles of the spotlight antenna 2. This adjustment is simple, convenient, quick, and time-saving, improving debugging and installation efficiency and safety. Furthermore, it facilitates subsequent adjustments to the angle of the spotlight antenna 2 during use, helping to obtain ideal performance data and meet the needs of different scenarios. This enhances the effectiveness of angle adjustment, expands the signal coverage of the spotlight antenna 2, provides higher quality communication, improves the ease of use of the spotlight antenna assembly 100, and reduces the impact on the signal stability and coverage 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 the side of the base 11 opposite to the second mounting member 5. In some embodiments, the two support portions 12 are spaced apart along a direction perpendicular to the rotation axis of the first mounting member 1.

[0076] In some embodiments, see Figure 7 The second drive module 6 is located on the side of the mounting part 51 opposite to the first mounting part 1.

[0077] The first drive module 3 is located on the side of the first mounting member 1 opposite to the mounting portion 51. This reduces interference between the second drive module 6 and the first drive module 3, saves space occupied by the second drive module 6, results in a more compact structure, reduces the size of the second mounting member 5, and lowers costs.

[0078] In some embodiments, see Figure 7 The second drive module 6 also includes a second support 63. The second driver 62 and the second support 63 are mounted on the side of the mounting part 51 opposite to 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 engaged with the first transmission member 60.

[0079] In some embodiments, the first mounting member 1 and the second mounting member 5 are rotatably connected relative to each other via a pivot 7. In some embodiments, see [reference needed]. Figure 4 The base 11 of the first mounting component 1 has a shaft hole 112. The shaft hole 112 is a non-rotational shape; for example, the shape of the shaft hole 112 can be square, triangular, etc. (See reference...) Figure 8 , Figure 8 The diagram shows a schematic of the structure of the rotating shaft 7 in some embodiments of this application. The spotlight antenna assembly 100 also includes a rotating shaft 7, which includes a rod 71, a head 72 connected to one end of the rod 71, and a connecting section 75 connected to the other end of the rod 71. The rotating shaft 7 also includes a first anti-rotation part 73 disposed between the rod 71 and the head 72. The cross-sectional shape of the first anti-rotation part 73 is adapted to the shape of the shaft hole 112, for example, the cross-sectional shape of the first anti-rotation part 73 can be square. The outer diameter of the head 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 nested and connected with the shaft hole 112, and the head 72 stops on the base 11, thereby connecting the rotating shaft 7 to the first mounting member 1. The first anti-rotation portion 73, in conjunction with the shaft hole 112, prevents the first mounting member 1 from rotating relative to the rotating shaft 7, allowing the rotation of the rotating shaft 7 to drive the first mounting member 1 to rotate. In some embodiments, the head 72 can be flat, reducing the portion of the head 72 protruding from the base 11 and minimizing interference.

[0080] Combination Figure 7 and Figure 8 As shown, the rotating shaft 7 also includes a second anti-rotation part 74 disposed 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 part 74. A locking nut 70 is connected to the connecting section 75 and locks the first transmission member 60 onto the rotating shaft 7, making it difficult for the first transmission member 60 to come off, thereby connecting the first transmission member 60 to the rotating shaft 7. The second anti-rotation part 74 prevents the first transmission member 60 from rotating relative to the rotating shaft 7, allowing the rotation of the first transmission member 60 to drive the rotating shaft 7 to rotate. At the same time, the first transmission member 60 restricts the rotating shaft 7 from disengaging from the second mounting member 5, realizing a rotatable connection between the first mounting member 1 and the second mounting member 5. The second worm gear 611 is driven to move by the second driver 62, which 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 component 60 includes a worm gear 601, and the second transmission component 61 includes a second worm 611, which is meshed with the worm gear 601.

[0082] The central axis of the worm gear 601 of the first transmission component 60 is collinear with the rotation axis of the first mounting component 1. The second worm 611 meshes with the worm gear 601, thus forming a worm gear mechanism. Through the worm gear mechanism, the horizontal azimuth angle of the spotlight antenna 2 can be adjusted quickly and sensitively. Because the worm gear mechanism has a self-locking function, it can maintain the horizontal azimuth angle of the spotlight antenna 2 even if the motor in the second drive module 6 fails. This achieves self-locking of the mechanism after the spotlight antenna 2 has adjusted its angle, improving the signal stability and signal coverage of the spotlight antenna 2.

[0083] In some embodiments, see Figure 6 and Figure 7 The spotlight antenna assembly 100 also includes a first limiting member 8, which is connected to one of the first mounting member 1 and the mounting portion 51. The other of the first mounting member 1 and the mounting portion 51 is provided with a first limiting portion 80, which is arc-shaped, and the center line of the arc of the first limiting portion 80 is collinear with the rotation axis of the first mounting member 1. The first limiting member 8 is connected to the first limiting portion 80 and is configured to move along the first limiting portion 80.

[0084] The first limiting part 80 can be an arc-shaped groove or an arc-shaped through hole. The first limiting part 80 can also be other arc-shaped structures. The first limiting part 80 is provided on the first mounting member 1 or the second mounting member 5. The first mounting member 1 and the second mounting member 5 are movably connected together by the first limiting member 80, allowing the first limiting member 8 to move along the first limiting part 80 without disengaging. For example, the first limiting part 80 can be an arc-shaped groove, and the first limiting member 8 is limited to sliding within the arc-shaped groove without disengaging. In some embodiments, combined with... Figure 4 and Figure 6 The base 11 of the first mounting component 1 has a first connecting hole 113, and the first limiting component 8 is connected to the first mounting component 1 through the first connecting hole 113. Figure 6 and Figure 7 The first limiting part 80 is an arc-shaped through hole opened on the mounting part 51 of the second mounting part 5. The first limiting part 8 has a limiting rod and baffles connected to both ends of the limiting rod. The limiting rod passes through the first connecting hole 113 and the arc-shaped through hole. The baffles at both ends of the limiting rod stop on the base 11 and the mounting part 51 respectively, so that the first limiting part 8 can slide along the arc-shaped through hole without falling out.

[0085] Thus, the first limiting member 8 and the first limiting part 80 cooperate to limit the relative rotation of the first mounting member 1 and the second mounting member 5, improve the stability of the relative rotation of the first mounting member 1 and the second mounting member 5, and help improve the stability of the spotlight antenna 2 rotating around the azimuth axis.

[0086] In some embodiments, see Figure 6 and Figure 7 The spotlight antenna assembly 100 also includes a second limiting member 9, which is connected to one of the first mounting member 1 and the mounting portion 51. The other of the first mounting member 1 and the mounting portion 51 is also provided with a second limiting portion 90, which is arc-shaped, and the center line of the arc of the second limiting portion 90 is collinear with the center line of the arc of the first limiting portion 80. The second limiting member 9 is connected to the second limiting portion 90 and is configured to move along the second limiting portion 90. The radius of the arc of the first limiting portion 80 is different from the radius of the arc of the second limiting portion 90.

[0087] The second limiting part 90 can be an arc-shaped groove or an arc-shaped through hole. The second limiting part 90 can also be other arc-shaped structures. In some embodiments, combined with... Figure 4 and Figure 6 A second connecting hole 114 is provided on the base 11 of the first mounting component 1, and the second limiting component 9 is connected to the first mounting component 1 through the second connecting hole 114. Figure 6 and Figure 7The second limiting part 90 is an arc-shaped through hole opened on the mounting part 51 of the second mounting member 5. The second limiting member 9 has a limiting rod and baffles connected to both ends of the limiting rod. The limiting rod passes through the second connecting hole 114 and the arc-shaped through hole. The baffles at both ends of the limiting rod stop on the base 11 and the mounting part 51 respectively, so that the second limiting member 9 can slide along the arc-shaped through hole without falling out.

[0088] By setting two limiting structures of different sizes, the relative rotation of the first mounting part 1 and the second mounting part 5 can be limited at different radial positions, and mutual interference can be reduced, which can further improve the stability of the relative rotation of the first mounting part 1 and the second mounting part 5.

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

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

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

[0092] That is, both the first limiting part 80 and the second limiting part 90 are large arcs, that is, greater than 180 degrees. In this way, the spotlight antenna assembly 100 can achieve a horizontal azimuth angle adjustment of ±180 degrees, increasing the angle adjustment range and improving the signal coverage effect of the spotlight antenna 2.

[0093] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.

[0094] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
