Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and in particular to a large-size lightweight reflector antenna. Background Technology

[0002] Large-size lightweight reflector antennas combine a wide coverage area with a lightweight structure. Through optimized material selection and structural design, they significantly reduce overall weight while maintaining the high gain and strong signal acquisition capabilities afforded by their large aperture, thus improving portability and installation efficiency. Suitable for satellite communications, radar detection, and other applications, they can be flexibly deployed in aerospace, terrestrial mobile base station, and other fields, balancing performance requirements with engineering practicality.

[0003] Large-size, lightweight reflector antennas operate by collecting and focusing electromagnetic waves through a reflector. The feed emits electromagnetic waves, which are reflected by the reflector to form a directional beam, or receive external electromagnetic waves and focus them back to the feed. The lightweight structure ensures the reflector maintains a high-precision curved shape, allowing the electromagnetic waves to propagate in a predetermined direction. Its core principle is to utilize the geometry of the reflector to adjust the phase and focus the energy of the electromagnetic waves. This enables long-distance, high-sensitivity signal transmission and detection in scenarios such as satellite communication and radar, balancing the performance advantages of large size with the engineering feasibility of lightweight design.

[0004] In existing technologies, the angle and elevation angle of some antennas are not easy to adjust, making it difficult to align with the target direction, which leads to a decrease in the quality of the communication link and problems such as weak signal and interruption. In particular, in satellite communication and radar detection, the target is easily lost due to azimuth deviation. To address these issues, a large-size lightweight reflector antenna is proposed.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a large-size lightweight reflector antenna, including a support column 1. The support column 1, as the core support component of the entire antenna structure, undertakes the important functions of fixing and supporting other components. It provides installation positions for key driving components such as motor 3 and motor 6, ensuring that these components can operate in a stable state. Simultaneously, the support column 1 also provides a stable support foundation for the rotation of the rotating column 2, ensuring that the rotating column 2 can rotate smoothly and accurately within a set range, thereby achieving azimuth adjustment of the antenna reflector. Motor 3 is fixedly connected inside the support column 1. Motor 3 is one of the main power sources for achieving azimuth adjustment of the antenna reflector. Through its own rotational motion, it drives the large gear 4 connected to it to rotate, which in turn drives the rotating column 2 to rotate through gear transmission, thereby achieving adjustment of the antenna reflector in the azimuth direction.

[0034] A large gear 4 is fixedly connected to the drive end of motor 3. The large gear 4 serves as a transmission component between motor 3 and rotating column 2, transmitting the rotational motion of motor 3 to the gear column 5 inside rotating column 2. Rotating column 2 is rotatably connected to the top of support column 1. Gear column 5 is fixedly connected inside rotating column 2. The outer side of the large gear 4 meshes with the outer side of gear column 5, serving as a key transmission component inside rotating column 2. It meshes with the large gear 4, transmitting the rotational motion of the large gear 4 to rotating column 2, thereby adjusting the azimuth angle of the antenna reflector. Motor 6 is fixedly connected inside support column 1, serving as the main power source for adjusting the elevation angle of the antenna reflector. A drive disk 7 is fixedly connected to the drive end of motor 6. The drive disk 7 serves as a connection component between motor 6 and belt 8, transmitting the rotational motion of motor 6 to belt 8, thereby adjusting the elevation angle of the antenna reflector.

[0035] A belt 8 is rotatably connected to the outer side of the drive disk 7. A rotating disk 9 is rotatably connected to the other end of the belt 8. The rotating disk 9 serves as a connecting component between the belt 8 and the first bevel gear 10, transmitting the rotational motion from the belt 8 to the first bevel gear 10. The top of the rotating disk 9 is fixedly connected to the first bevel gear 10, which transmits the rotational motion of the rotating disk 9 to the rotating shaft 12 via bevel gear transmission. The rotating shaft 12 is fixedly connected inside the rotating column 2. The rotating shaft 12 is a key component for adjusting the elevation angle of the antenna reflector. A second bevel gear 11 is fixedly connected to the outer side of the rotating shaft 12. The outer side of the first bevel gear 10 and the outer side of the second bevel gear 11 are meshed, transmitting the power of the second motor 6 to the rotating shaft 12. A fixing block 13 is fixedly connected to the outer side of the rotating shaft 12, and a disassembly assembly for easy maintenance is fixedly connected to the top of the fixing block 13.

[0036] Reference Figure 1 , Figure 4 , Figure 5 The disassembly assembly includes a connecting platform 14, the bottom of which is fixedly connected to the top of the fixing block 13. A receiving surface 15 is fixedly connected to the top of the connecting platform 14. The connecting platform 14 connects the fixing block 13 and the receiving surface 15, serving as a transition and support. A frustum 16 is fixedly connected to the top of the receiving surface 15, providing an installation position for subsequent components. Two motors 17 are fixedly connected inside the frustum 16, which are the power source for the disassembly assembly of the receiving rod 29. A pinion 18 is fixedly connected to the drive end of each of the two motors 17. The pinion 18 is a transmission component between the motors 17 and the transmission gear 19, used to transmit the power of the motors 17 to the transmission gear 19, thereby driving the threaded rod 20 to rotate.

[0037] The support column 1 has two threaded rods 20 internally connected to it. These threaded rods 20 are key components for adjusting the height of the slider 21. A transmission gear 19 is fixedly connected to the bottom end of each threaded rod 20. The outer side of the transmission gear 19 meshes with the outer side of the pinion 18. A receiving rod 29 is mounted on the top of the frustum 16. The receiving rod 29 is the receiving part of the antenna reflector, used to receive signals. Two pressure blocks 27 are mounted on the top of the receiving rod 29 to fix it and ensure its stability during operation. Two pressure blocks 27 are fixedly connected to opposite sides with round rods 23, which control the movement and rotation of the pressure blocks 27. Slider blocks 21 are rotatably connected to both the front and rear sides of the round rods 23, supporting the round rods 23. Half gears 24 are fixedly connected to the outer side of the round rods 23. Multiple support blocks 22 are fixedly connected to the top of the frustum 16. Racks 25 are fixedly connected to the outer sides of the two rear support blocks 22, providing mounting positions for the racks 25 and providing stable support through their fixed connection with the frustum 16. The adjacent sides of the racks 25 are meshed with the outer sides of the half gears 24. The racks 25 and half gears 24 work together to allow the pressure blocks 27 to rotate 90 degrees. A lead screw 26 is threaded into the interior of the rear slider 21.

[0038] Reference Figures 3 to 5 The outer side of the gear column 5 is rotatably connected to the inside of the support column 1. The gear column 5 can rotate freely within the support column 1 without axial movement. The bottom end of the rotating disk 9 is rotatably connected to the inside of the support column 1. The outer side of the rotating disk 9 is rotatably connected to the inside of the gear column 5. This connection method allows the rotating disk 9 and the gear column 5 to rotate independently without interfering with each other. This design allows the antenna reflector to perform azimuth and elevation angle adjustments independently without affecting each other. The outer side of the fixing block 13 contacts the inner side of the rotating column 2. Multiple limiting posts 28 are fixedly connected inside the pressure block 27. The outer sides of the multiple limiting posts 28 are slidably connected to the inside of the receiving rod 29, realizing the stable fixation of the receiving rod 29 by the pressure block 27. The inner thread of the front slider 21 is connected to the outer side of the threaded rod 20. The rotation of the threaded rod 20 is converted into the linear motion of the slider 21 through thread transmission. The outer side of the slider 21 is slidably connected to the inside of the support block 22. The support block 22 provides stable support and guidance for the slider 21, ensuring the smooth movement of the slider 21. The outer side of the round rod 23 is slidably connected to the inside of the support block 22, which provides stable support for the round rod 23. The bottom end of the lead screw 26 is fixedly connected to the top of the frustum 16. The top end of the transmission gear 19 is rotatably connected to the inside of the frustum 16, and the rear side of the half gear 24 is slidably connected to the front side of the rear support block 22.

[0039] Working principle: The operator starts motor 3, which drives the large gear 4. The movement of the large gear 4 causes the gear column 5 to rotate, which in turn drives the rotating column 2 to rotate, thus achieving horizontal rotation of the large-size lightweight reflector antenna. Then, motor 6 is started, which outputs power to drive the drive disk 7 to rotate. The drive disk 7 causes the belt 8 to drive the rotating disk 9 to rotate. At this time, bevel gear 10 rotates along with the rotating disk 9. The rotation of bevel gear 10 causes bevel gear 11 to drive the connecting platform 14 to rotate, thus achieving vertical rotation of the large-size lightweight reflector antenna. This enables multi-angle adjustment of the large-size lightweight reflector antenna, allowing it to accurately align with the target, dynamically optimize signal quality, enhance environmental adaptability, and expand applications in multiple scenarios.

[0040] When installing the receiver rod 29, start motor 3 17. Motor 3 17 starts moving and causes pinion 18 to drive transmission gear 19 to rotate. The rotation of transmission gear 19 causes threaded rod 20 to rotate and drives slider 21 to move downward. At this time, half gear 24 passes between the teeth of rack 25, causing round rod 23 to drive pressure block 27 to rotate 90 degrees and then continue to move downward until it contacts receiver rod 29. At this time, limit post 28 enters the groove of receiver rod 29, completing the installation of receiver rod 29. Start receiver rod 29 again, and all components move in the opposite direction. Remove receiver rod 29 to complete disassembly. This achieves the effect of convenient disassembly, which makes receiver rod 29 easy to maintain and quick to replace, improves the reliability and maintenance efficiency of antenna equipment, and facilitates equipment upgrades or adaptation to different functional modules, enhancing application flexibility.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
