Description

Technical Field

[0001] The present invention belongs to the field of communication technology, and in particular relates to a double-sided double-folded antenna reflection device. Background Art

[0002] Compared with fixed-station antennas, the new mobile measurement and control data transmission antenna has significant advantages in site flexibility and rapid transfer. Compared with vehicle-mounted antennas, this new type of antenna has stronger adaptability when facing harsh road conditions and other environmental conditions, and can be quickly relocated to global hot spots through various modes of transportation such as aviation and ships, reflecting superior transportation mobility.

[0003] These antennas and their platform systems usually use containers (width 2438mm) as storage and carrying platforms, integrating all equipment and functions in a compact space. This design allows the antenna to be configured as one station per box, with automatic opening and closing functions, and can adapt to flexible transportation needs. However, the reflective surface of the antenna is its key component, and its storage size has a decisive influence on the transportation method and site adaptability.

[0004] The main forms of existing reflector designs include non-foldable and double-sided single-folding. Due to its large diameter, the non-foldable reflector cannot be effectively stored inside the container, so its use and transfer will be restricted when the container size is limited. Although the double-sided single-folding design can be partially folded to reduce the occupied space, it is still difficult to effectively store it in the container because the storage size after folding is still large, which also limits the flexibility and rapid deployment capability of the antenna.

[0005] Therefore, in order to improve the transport mobility and adaptability of the new mobile measurement and control data transmission antenna, it is necessary to design a reflector structure with higher foldability and compactness. By improving the reflector design, it can be effectively folded and stored in a limited space, thereby ensuring the adaptability in the container and improving the overall transportation and deployment efficiency of the antenna. This technical improvement will help the rapid deployment and flexible application of the antenna in various environments, further enhancing its mobility around the world. Summary of the invention

The petal-splitting electric push rod, the petal-splitting pin cone positioning seat and the petal-splitting electromagnet are all movably connected to the petal-splitting folding surface and can be locked to fix the petal-splitting folding surface.

[0013] The main drive assembly includes a main motor, a main worm gear reducer and a main planetary reducer which are sequentially connected to the main motor; the fixed panel is connected to the base of the main planetary reducer via a connecting plate; and the main folding surface is connected to the output shaft of the main planetary reducer via a main hinge bracket.

[0016] The main driving component is arranged at one end of the connection between the fixed panel and the main folding surface, and the other end of the connection between the fixed panel and the main folding surface is provided with a master-slave component, and the master-slave component is respectively movably connected with the fixed panel and the main folding surface; the petal driving component is arranged at one end of the connection between the main folding surface and the petal folding surface, and the other end of the connection between the main folding surface and the petal folding surface is provided with a petal driven component, and the petal driven component is respectively movably connected with the main folding surface and the petal folding surface.

[0017] Compared with the prior art, the present invention has the following beneficial effects: Through the connection design between the fixed panel and the main folding surface, the main folding surface can be flipped through the main drive assembly, so that a parabolic structure is formed when unfolded, and the fixed panel and the main folding surface can achieve the best reflection effect together.

At the same time, this structural design ensures the rigidity and stability of the reflective surface in the working state, and improves the overall performance and reliability of the system.

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively and meticulously below in conjunction with the accompanying drawings and preferred embodiments of the present invention, but the protection scope of the present invention is not limited to the following specific embodiments.

[0024] Unless otherwise defined, all professional terms used below have the same meanings as those generally understood by those skilled in the art. The professional terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the scope of protection of the present invention.

[0025] Unless otherwise specified, various raw materials, reagents, instruments and equipment used in the present invention can be purchased from the market or prepared by existing methods.

[0026] Example: like Figure 1-Figure 3As shown, the double-sided double-folding antenna reflector device of this embodiment includes a main body 1, a fixed panel 2 is provided on the main body 1, and the two opposite sides of the fixed panel 2 are movably connected with main folding surfaces 3, and each main folding surface 3 is movably connected with a petal folding surface 4 on the side away from the fixed panel 2; a main driving component 5 is provided on the fixed panel 2, and the driving end of the main driving component 5 is connected to each main folding surface 3, and can drive each main folding surface 3 to flip, so that each main folding surface 3 can be switched between an expanded state forming a parabolic structure with the fixed panel 2, and a folded state forming a folded state with the fixed panel 2; a petal driving component 6 is provided on each main folding surface 3, and the driving end of the petal driving component 6 is connected to each petal folding surface 4, and can drive each petal folding surface 4 to flip, so that the petal folding surface 4 can be switched between an expanded state forming a parabolic structure with the main folding surface 3, and a folded state forming a folded state with the main folding surface 3. Through the connection design between the fixed panel 2 and the main folding surface 3, the main folding surface 3 can be flipped through the main drive component 5, so that a parabolic structure is formed when unfolded, and the fixed panel 2 and the fixed panel 2 achieve the best reflection effect. When folded, the main folding surface 3 can be compactly stored, optimizing the use of space. The petal folding surface 4 is connected to the main folding surface 3 through the petal drive component 6, so that the petal folding surface 4 can be folded and unfolded together with the main folding surface 3. This design increases the flexibility of the reflective surface, allows a more compact folding structure, and provides a complete reflective surface when unfolded. Through the combination of the main folding surface 3 and the petal folding surface 4, the reflective surface can effectively reduce the space it occupies in the folded state, with a width of only 2232mm, which is suitable for storage in a standard container (2438mm). This design solves the problem that the traditional antenna reflective surface cannot be stored due to its large size, and significantly improves the flexibility of transportation and deployment. Through the automatic control of the main drive component 5 and the petal drive component 6, the unfolding and folding of the reflective surface can achieve high-precision position adjustment. At the same time, this structural design ensures the rigidity and stability of the reflective surface in working condition, and improves the overall performance and reliability of the system.

[0027] In this embodiment, the backs of the fixed panel 2, the main folding surface 3 and the petal folding surface 4 are all supported and connected to a back frame 8 through a plurality of splicing pieces 7. The structural stability and overall rigidity of the reflective surface can be significantly enhanced. The uniform distribution of the plurality of splicing pieces 7 provides good support for the back frame 8, optimizes the load distribution, reduces local stress concentration, and thus improves the durability and precision of the reflective surface. The support of the back frame 8 enables the reflective surface to maintain a precise geometric shape in the unfolded state, ensuring its stability during use. At the same time, the modular design of the splicing pieces 7 simplifies the assembly and adjustment process of the reflective surface, and improves production efficiency and maintenance convenience. In addition, this structural design also allows the reflective surface to be compactly stored in a folded state, which is convenient for transportation and storage, thereby improving the maneuverability and efficiency of the system.

[0028] In this embodiment, the splicing piece 7 includes a profile adjustment screw and an angle piece. This helps to optimize the structural stability and accuracy of the reflective surface. The profile adjustment screw is used to accurately adjust the profile position of the fixed panel 2, the main folding surface 3 and the petal folding surface 4 to ensure that they can be accurately docked in the unfolded state to maintain the high-precision geometry of the reflective surface. This adjustment mechanism not only improves the overall rigidity and stability of the reflective surface, but also allows fine-tuning during the assembly process to meet strict performance requirements. The angle piece plays the role of strengthening the connection, further enhancing the connection strength and load distribution capacity between the back frame 8 and each panel. This structural design effectively improves the durability of the reflective surface and simplifies the assembly and maintenance process, so that the reflective surface can maintain excellent performance and reliability during folding and unfolding.

[0029] In this embodiment, the fixed panel 2, the main folding surface 3, the petal folding surface 4 and the back frame 8 are all carbon fiber sandwich structures.

[0030] In this embodiment, a main electric push rod 21, a main pin cone positioning seat 22 and a main electromagnet 23 are provided on the side of the fixed panel 2 close to each main folding surface 3. The main electric push rod 21, the main pin cone positioning seat 22 and the main electromagnet 23 are all movably connected to the main folding surface 3 and can be locked to fix the main folding surface 3. The carbon fiber sandwich structure not only provides excellent strength and rigidity, but also has lightweight characteristics, which helps to reduce the total weight of the reflecting surface, thereby improving the transportation and maneuverability of the system. The high strength characteristics of carbon fiber ensure the stability and durability of the reflecting surface in the working state, while the sandwich structure effectively enhances the impact resistance and structural stability. In addition, the use of carbon fiber materials also improves the thermal stability and corrosion resistance of the reflecting surface, ensuring reliability under various environmental conditions. The selection of this high-performance material enables the reflecting surface to meet the requirements of high precision and high stability while ensuring structural strength, thereby improving the overall function and service life of the antenna system.

[0031] In this embodiment, a petal electric push rod 31, a petal pin cone positioning seat 32 and a main petal electromagnet 33 are provided on the side of the main folding surface 3 close to the petal folding surface 4. The petal electric push rod 31, the petal pin cone positioning seat 32 and the petal electromagnet 33 are all movably connected to the petal folding surface 4 and can be locked to fix the petal folding surface 4. The petal electric push rod 31 is used to accurately control the unfolding and folding of the petal folding surface 4 to achieve high-precision operation. The petal pin cone positioning seat 32 provides a stable positioning function to ensure that the petal folding surface 4 can be accurately docked in the unfolded state and form the required geometric structure with the main folding surface 3. In addition, the main petal electromagnet 33 can provide a strong locking effect when needed to ensure that the petal folding surface 4 can be stably fixed after unfolding, thereby avoiding any displacement or loosening during operation. This design not only enhances the overall stability and structural accuracy of the reflecting surface, but also simplifies the operation process and improves the reliability and work efficiency of the system.

[0032] In this embodiment, the main drive assembly 5 includes a main motor 51, a main worm gear reducer 52 and a main planetary reducer 53 which are sequentially connected to the main motor 51, the fixed panel 2 is connected to the base of the main planetary reducer 53 through a connecting plate 54, and the main folding surface 3 is connected to the output shaft of the main planetary reducer 53 through a main hinge bracket 55. The main motor 51, as the main power source, realizes the initial deceleration and torque amplification of the power through the main worm gear reducer 52, and then further decelerates and increases the output torque through the main planetary reducer 53, so as to accurately control the movement of the main folding surface 3. The fixed panel 2 is connected to the base of the main planetary reducer 53 through the connecting plate 54, ensuring the stability and accurate docking of the fixed panel 2. The main folding surface 3 is connected to the output shaft of the main planetary reducer 53 through the main hinge bracket 55, realizing the stable rotation and accurate folding of the main folding surface 3. Such a design not only optimizes the power transmission and control accuracy, but also improves the stability and reliability of the entire folding and unfolding process. The structure of the main drive assembly 5 enables smooth and precise movement of the reflective surface during unfolding and folding, ensuring efficient operation and long-term stability of the system. This configuration effectively combines power transmission and mechanical support to ensure high performance and reliability of the reflective surface.

[0033] In this embodiment, a limiting groove is provided on the main hinge bracket 55, and the connecting plate 54 is screwed to the limiting screw, and the limiting screw is movably inserted in the limiting groove. The cooperation between the limiting groove and the limiting screw enables the folding and unfolding process of the main folding surface 3 to be carried out within a precisely controlled range, ensuring the stability and accuracy of the main folding surface during movement. The setting of the limiting screw enables reliable mechanical limiting through the limiting groove when the main folding surface 3 is unfolded to a specific position, which effectively prevents excessive rotation or position displacement of the main folding surface 3 during operation. In this way, the reflective surface can accurately reach a predetermined unfolding angle and be securely fixed when stored, avoiding structural damage or functional failure caused by inaccurate folding angles. In addition, the adjustment function of the limiting screw allows fine-tuning in actual use to meet the accuracy requirements under different operating conditions. This design enhances the adjustability and flexibility of the system, while improving the overall durability and reliability of the reflective surface.

[0034] In this embodiment, the petal drive assembly 6 includes a petal motor, a petal worm gear reducer and a petal planetary reducer which are sequentially connected to the petal motor. The output end of the petal planetary reducer is connected to the petal wheel through a silent chain. The main folding surface 3 is connected to the base of the petal planetary reducer through a mounting plate, and the petal folding surface 4 is connected to the petal wheel through a petal hinge bracket. The petal motor is used as the main power source, and the petal worm gear reducer is used to achieve preliminary deceleration and torque amplification. Then the petal planetary reducer is further decelerated and the output torque is increased to ensure precise power control. The output end of the petal planetary reducer is connected to the petal wheel through a silent chain, providing a smooth and low-noise power transmission. This chain transmission method not only reduces the motion noise, but also improves the stability and reliability of the transmission. The main folding surface 3 is connected to the base of the petal planetary reducer through a mounting plate, ensuring a stable connection between the petal drive assembly and the main folding surface. The petal folding surface 4 is connected to the petal wheel through a petal hinge bracket, achieving precise control and stable movement of the petal folding surface 4. The design of the petal hinge bracket ensures that the petal folding surface 4 can cooperate smoothly with the main folding surface 3 to complete the folding and unfolding operations. This comprehensive design not only improves the movement accuracy and stability of the petal folding surface 4, but also optimizes the power transmission and control accuracy of the entire drive system, thereby enhancing the overall performance and reliability of the reflective surface system.

[0035] In this embodiment, the main drive component 5 is arranged at one end of the connection between the fixed panel 2 and the main folding surface 3, and the other end of the connection between the fixed panel 2 and the main folding surface 3 is provided with a master-slave component, and the master-slave component is movably connected to the fixed panel 2 and the main folding surface 3 respectively. The petal drive component 6 is arranged at one end of the connection between the main folding surface 3 and the petal folding surface 4, and the other end of the connection between the main folding surface 3 and the petal folding surface 4 is provided with a petal slave component, and the petal slave component is movably connected to the main folding surface 3 and the petal folding surface 4 respectively. The main drive component 5 is arranged at one end of the connection between the fixed panel 2 and the main folding surface 3, and the master-slave component is arranged at the other end, to ensure the stable connection and precise control between the main folding surface 3 and the fixed panel 2. Similarly, the petal drive component 6 is arranged at one end of the connection between the main folding surface 3 and the petal folding surface 4, and the petal slave component is arranged at the other end, to ensure the stable connection and active coordination between the petal folding surface 4 and the main folding surface 3. This design improves the folding and unfolding accuracy of the reflective surface, enhances structural stability, reduces the risk of mechanical failure, and optimizes space utilization, allowing the reflective surface to be compactly stored in a standard container, thereby increasing transportation and deployment flexibility.

[0036] In this embodiment, sensors for detecting the unfolding state and the folding state are provided on both the main folding surface 3 and the petal folding surface 4. The setting of the sensors enables the system to monitor the state of each part of the reflective surface in real time, thereby realizing precise control of the unfolding and folding process. These sensors can provide feedback information about the current state of the main folding surface 3 and the petal folding surface 4, ensuring that they can accurately reach the predetermined position and angle during operation. By monitoring the real-time state of the reflective surface, the system can adjust the operation of the drive assembly in time to prevent structural damage or functional failure caused by position deviation. In addition, the real-time feedback function of the sensors helps to improve the automation level and operational safety of the system. They can detect any abnormal situation during the folding or unfolding process, and make adjustments or alarms through the system control mechanism, thereby ensuring the normal operation of the equipment and reducing the risk of human operational errors. This sensor configuration not only improves the accuracy and stability of the reflective surface system, but also enhances the flexibility and safety of operation, so that the reflective surface can work efficiently and reliably under various environmental conditions.

[0037] The operation process includes the following steps: Unfolding process: the main drive assembly 5 is started, the main motor 51 drives the main worm gear reducer 52 and the main planetary reducer 53, driving the main folding surface 3 to unfold through the main hinge bracket 55. At the same time, the petal drive assembly 6 is started, the petal motor drives the petal worm gear reducer and the petal planetary reducer, driving the petal folding surface 4 to unfold through the silent chain and the petal hinge bracket. The sensor detects the unfolding state to ensure that the main folding surface 3 and the petal folding surface 4 are accurately unfolded and locked to form a complete parabolic structure.

[0038] Folding process: First, the petal drive assembly 6 starts to fold, and the petal motor drives the petal folding surface 4 to fold back to the main folding surface 3 through the petal worm gear reducer and the petal planetary reducer. Then, the main drive assembly 5 is started, and the main motor 51 drives the main worm gear reducer 52 and the main planetary reducer 53 to drive the main folding surface 3 to fold back to the fixed panel 2. The sensor detects the folding state to ensure that the reflective surface is compactly stored in the container.
