[0046] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0047] As explained in the background section above, although existing 5G base station antenna stabilization mechanisms are...

[0048] The existing 5G base station antenna stabilization mechanism is mature and stable; however, for the application scenario of mounting a 5G antenna on a tethered balloon, the existing 5G base station antenna stabilization mechanism is difficult to meet the usage requirements of antenna rotation and pitch, but not frequent shaking.

[0049] The tethered balloon platform is used for 5G communication experiments. It requires that the antenna, after launch, stably align with a fixed or moving target, enabling the antenna to rotate horizontally and vertically, but without frequent shaking.

[0050] Balloons in the air undergo various attitude changes such as pitching, rolling, translating, and rotating due to airflow, which significantly impacts the communication environment. Tethered balloons, with their large size and floating bodies, are difficult to control, necessitating a focus on fixing the direction of 5G antennas or achieving automatic gravity-based orientation adjustment.

[0051] The price of a conventionally used 3D gimbal is over 1 million yuan, which is very expensive. 3D gimbals consume a lot of power, and the existing power supply capacity of the tethered balloon platform cannot meet its power requirements. Furthermore, modifying the power supply system is costly and time-consuming. The test environment involved sudden, large gusts of wind, but mostly a relatively stable wind field.

[0052] To address the issues of existing 5G base station antenna stabilization mechanisms failing to meet the antenna usage requirements of tethered balloons, and the excessively high cost of 3D gimbals, this invention provides...

[0053] A gravity-adaptive ball-borne antenna stabilization mechanism is required to achieve better energy absorption and protection when the antenna sways due to gusts of wind.

[0054] The present invention provides the following specific embodiments, which can be combined with each other. For the same or similar concepts or processes, they may not be described again in some embodiments.

[0055] Figure 1 This is a schematic diagram of the gravity-adaptive ball-borne antenna stabilization mechanism provided in an embodiment of the present invention. Figure 2 for Figure 1 The illustrated embodiment provides a three-dimensional structural diagram of a gravity-adaptive ball-borne antenna stabilization mechanism. The gravity-adaptive ball-borne antenna stabilization mechanism provided in this embodiment may include: a suspension steel frame 1, a gimbal 2, a connecting steel frame 3, an electric actuator 4, a 5G antenna 6, a damping rod 7, and a single-axis gimbal 11.

[0056] like Figure 1 and Figure 2 In the structure of the spherical antenna stabilization mechanism shown, the suspension steel frame 1 is configured as a frame structure, and the single-axis gimbal 11 is placed inside the frame structure of the suspension steel frame 1 through its auxiliary structural components. Specifically, an internal bracket 11a is fixedly connected to the bottom of the single-axis gimbal 11, and the internal bracket 11a is connected to the 5G antenna 6 through a universal joint 2 and a connecting steel frame 3. A gimbal mounting base 11b is rotatably connected to the top of the single-axis gimbal 11, and the gimbal mounting base 11b is mounted on the top of the suspension steel frame 1. The installation and connection of the single-axis gimbal 11 and the gimbal mounting base 11b enable the single-axis gimbal 11 to perform planar rotation below the gimbal mounting base 11b, which allows the single-axis gimbal 11 to drive the internal bracket 11a, the universal joint 2, the connecting steel frame 3, and the 5G antenna 6 connected below to perform a horizontal rotation.

[0057] In the embodiment of the present invention, the structure in which the single-axis gimbal 11 drives the 5G antenna 6 to rotate horizontally is such that when the single-axis gimbal 11 drives the internal bracket 11a to rotate horizontally, the power transmission for changing the angle of the 5G antenna 6 is realized through the universal joint 2.

[0058] In the ball-borne antenna stabilization mechanism provided in this embodiment of the invention, the damping rod 7 is installed between the internal bracket 11a and the 5G antenna 6, and is used to make the 5G antenna 6 return to the gravity line reference when the 5G antenna 6 swings in the pitch direction.

[0059] In the ball-borne antenna stabilization mechanism provided in this embodiment of the invention, the electric push rod 4 is installed between the connecting steel frame 3 and the 5G antenna 6, and is used to pre-adjust the suspension angle of the 5G antenna 6.

[0060] The gravity-adaptive ball-mounted antenna stabilization mechanism provided in this embodiment of the invention, on the one hand, enables the 5G antenna 6 to perform translational rotation through the single-axis gimbal 11 and its indirect connection with the 5G antenna 6, meeting the translational rotation requirements of the 5G antenna 6; on the other hand, by installing a damping rod 7 that is linked to the 5G antenna 6, the 5G antenna 6 can return to the gravity line reference in a very short time when it sways due to the air environment, and the sway of the 5G antenna 6 can be controlled to only a small angle, thus achieving the gravity-adaptive capability of the 5G antenna 6; furthermore, by installing an electric push rod 4 that is linked to the 5G antenna 6, the 5G antenna 6 can be mounted and installed using this ball-mounted antenna stabilization mechanism, and the suspension angle of the 5G antenna 6 can be adjusted, thus meeting the installation requirements of the antenna for different initial pitch angles. Using the gravity-adaptive ball-mounted antenna stabilization mechanism provided in this embodiment of the invention, when a gust of wind occurs, the stabilization mechanism can quickly stabilize the antenna, and the antenna sway can be controlled within 0.4 degrees; in addition, it has the advantages of simple installation and disassembly, and cost savings.

[0061] In one implementation of this invention, such as Figure 2 As shown, the connecting steel frame 3 includes a horizontally arranged channel steel beam, two vertical channel steel columns fixedly connected to the lower ends of the channel steel beam by bolts, and a connecting steel channel 9 for connecting the channel steel beam and the vertical channel steel columns; the connecting steel frame 3 hangs a 5G antenna 6 at the ends of the two vertical channel steel columns, and the damping rod 7 keeps the hung 5G antenna 6 at the pitch angle of its gravity line reference.

[0062] In one implementation of this invention, such as Figure 2 As shown, the ball-borne antenna stabilization mechanism also includes: antenna frame 5 and pitch rotation shaft 8.

[0063] In this implementation, the 5G antenna 6 is fixedly mounted on the antenna frame 5 and is hung on the ends of the two vertical channel steel columns connecting the steel frame 3 via the antenna frame 5. In a specific implementation, a pitch pivot 8 is fixedly mounted on the lugs on both sides of the antenna frame 5 and is hung on the ends of the two vertical channel steel columns connecting the steel frame 3 via the pitch pivot 8. During the installation process, the center of gravity of the 5G antenna 6 is controlled to be located on the central axis of the pitch pivot 8, so that when the antenna shakes, it can return to the gravity line reference position by itself through the action of the damping rod 7.

[0064] In practical applications, this invention embodiment includes two damping rods 7 and two electric actuators 4. The two damping rods 7 are respectively positioned at both ends of the pitch axis 8; one end of each damping rod 7 is connected to the bottom of the internal bracket 11a, and the other end is fixedly connected to the pitch axis 8, used to suppress the swaying of the 5G antenna 6 caused by the wind field and to allow the 5G antenna 6 to return to the gravity line reference.

[0065] Two electric actuators 4 are also respectively set at both ends of the elevation shaft 8; each electric actuator 4 includes an upper round rod and a lower angle steel, and is connected in the middle by a rod end connector 10. One end of the rod is connected to the top of the vertical channel steel column on one side of the connecting steel frame 3, and the other end is fixedly connected to the elevation shaft 8. The ball-borne antenna stabilization mechanism is used to pre-adjust the suspension angle of the 5G antenna 6, i.e., the initial elevation angle, through the electric actuators 4.

[0066] Additionally, it should be noted that the spherical antenna stabilization mechanism provided in this embodiment of the invention is suspended below the tethered balloon by connecting the gondola tension line at the top of the suspension steel frame 1 to the sphere of the tethered balloon.

[0067] The gravity-adaptive ball-mounted antenna stabilization mechanism provided in this embodiment of the invention, on the one hand, enables the 5G antenna 6 to perform translational rotation through the single-axis gimbal 11 and its indirect connection with the 5G antenna 6, meeting the translational rotation requirements of the 5G antenna 6; on the other hand, by installing a damping rod 7 that is linked to the 5G antenna 6, the 5G antenna 6 can return to the gravity line reference in a very short time when it sways due to the aerial environment, and the sway of the 5G antenna 6 can be controlled to be only a small angle, thus achieving the gravity-adaptive capability of the 5G antenna 6; furthermore, by installing an electric push rod 4 that is linked to the 5G antenna 6, the 5G antenna 6 can be mounted and installed using this ball-mounted antenna stabilization mechanism, and the suspension angle of the 5G antenna 6 can be adjusted, thus meeting the installation requirements of the antenna for different initial pitch angles. The technical solution of this embodiment of the invention has the following beneficial effects:

[0068] (1) The single-axis gimbal 11 can achieve three-dimensional control of 5G antenna, and it is low in cost, easy to install, and saves power consumption of equipment on tethered balloons.

[0069] (2) Tethered balloons will experience pitch, roll, translation and rotation in the air under the influence of airflow. After installing a 5G antenna using the spherical antenna stabilization mechanism provided in this embodiment of the invention, the 5G antenna on it can be stably aligned with a fixed or moving target after it is launched into the air, and the antenna can also be rotated and pitched.

[0070] (3) When the 5G antenna is mounted on the ball-borne antenna stabilization mechanism provided in the embodiment of the present invention, the antenna sway is minimal and can be controlled within 0.4 degrees. Even if the antenna sways due to wind, the damping rod 7 can quickly bring the antenna back to the gravity line reference, resulting in high stability.

[0071] The following is a specific implementation example illustrating the detailed implementation of the gravity-adaptive spherical antenna stabilization mechanism provided in this invention.

[0072] Implementation Example

[0073] Reference Figure 1 and Figure 2 The gravity-adaptive ball-borne antenna stabilization mechanism shown includes: a suspension steel frame 1, a universal joint 2, a connecting steel frame 3, an electric push rod 4, an antenna frame 5, a 5G antenna 6, a damping rod 7, a pitch pivot 8, a connecting steel channel 9, a rod end connector 10, and a single-axis gimbal 11, as well as an internal bracket 11a and a gimbal mounting base 11b.

[0074] In this implementation example, the suspension steel frame 1 is assembled from multiple steel rods by welding or bolting to form a frame structure. The suspension steel frame 1 is connected to the bottom of the tethered balloon by the gondola tension line, thereby suspending the entire spherical antenna stabilization mechanism below the tethered balloon.

[0075] In this implementation example, the single-axis gimbal 11 is placed inside the frame structure of the suspension steel frame 1 through its mounting structure. Specifically, the bottom end of the single-axis gimbal 11 is fixedly connected to an internal bracket 11a, and the internal bracket 11a is connected to the 5G antenna 6 through a universal joint 2 and a connecting steel frame 3. The gimbal mounting base 11b, which is rotatably connected to the top of the single-axis gimbal 11, is mounted on the top of the suspension steel frame 1. The single-axis gimbal 11 can perform horizontal rotation at the bottom of the gimbal mounting base 11b, and the variable angle power transmission to the 5G antenna 6 is realized through the connection structure of the universal joint 2.

[0076] In this implementation example, the connecting steel frame 3 is composed of a horizontal channel steel beam and two vertical channel steel columns connected by bolts, and the connection positions of the horizontal channel steel beam and the vertical channel steel columns are fixedly connected by the connecting steel channel 9.

[0077] In this implementation example, the 5G antenna 6 is fixedly mounted on the antenna frame 5, and a pitch pivot 8 is fixedly mounted on the antenna frame 5. That is, the antenna frame 5 is suspended from the ends of two vertical channel steel columns connecting the steel frame 3 via the pitch pivot 8, allowing the antenna frame 5 to rotate synchronously with the pitch pivot 8. It should be noted that during installation, care must be taken to ensure that the center of gravity of the 5G antenna 6 is located on the central axis of the pitch pivot 8.

[0078] In this implementation example, two electric actuators 4 are provided, respectively located at both ends of the pitch axis 8. The electric actuator 4 consists of an upper round rod and a lower angle steel connected by a rod end connector 10. One end of the actuator is connected to the top of the vertical channel steel column on one side of the connecting steel frame 3, and the other end is fixedly connected to the pitch axis 8. The suspension angle of the 5G antenna 6 can be pre-adjusted through the electric actuator 4, that is, the initial pitch angle of the 5G antenna 6 during installation can be set.

[0079] In this implementation example, there are two damping rods 7, which are respectively set at both ends of the pitch axis 8. One end of the rod is connected to the bottom end of the internal bracket 11a, and the other end is fixedly connected to the pitch axis 8. By controlling the center of gravity of the 5G antenna 6 to be located on the central axis of the pitch axis 8, the connection of the damping rods 7 can suppress the swaying of the 5G antenna 6 caused by the wind field and make the 5G antenna 6 return to the gravity line reference.

[0080] This invention provides a stabilization mechanism for a tethered balloon-borne 5G antenna that adaptively adjusts to its own gravity. When the antenna sways due to wind or sudden gusts, it can quickly suppress the swaying and bring the antenna back to its gravity reference. It has the following effects:

[0081] (1) Compared with a 3D gimbal that can achieve the same effect, its cost and power consumption are greatly reduced, and the trouble of modifying the power supply system is also eliminated.

[0082] (2) After the spherical 5G antenna is launched, it can be stably aligned with a fixed or moving target. Even in the air, under the influence of airflow, it can suppress frequent shaking and realize antenna rotation and pitch.

[0083] While the embodiments disclosed in this invention are as described above, they are merely illustrative of the embodiments to facilitate understanding of the invention and are not intended to limit the invention. Any person skilled in the art to which this invention pertains may make any modifications and variations in the form and details of the implementation without departing from the spirit and scope disclosed herein; however, the scope of patent protection for this invention shall still be determined by the scope defined in the appended claims.
