Description

Technical Field

[0001] The present invention relates to the technical field of space docking of spacecrafts, and specifically to an unlockable passive docking device for an antenna module. Background Art

[0002] In the era of booming space technology today, as a key device for spacecrafts to achieve functions such as communication, remote sensing, and navigation, the performance and reliability of space antennas are crucial. The docking technology of space antenna modules directly affects the installation, debugging, and subsequent stable operation of antennas. However, there are many problems with existing space antenna module docking devices, which seriously restrict the smooth progress of space missions.

[0003] Traditional docking devices are difficult to effectively restrict the positions of various components in a complex space environment. Micro-meteorite impacts in the space environment, vibrations generated by spacecraft attitude adjustments, etc. may all cause the docking components to shake and shift. This will not only affect the accuracy of antenna module docking, but may also cause loose connections, thereby interfering with signal transmission, reducing antenna performance, and even making the entire communication, remote sensing, etc. systems unable to work properly.

[0004] The installation and disassembly processes of existing docking devices are often cumbersome. In space operations, each operation requires a large amount of time and effort. The complex installation process increases the operation difficulty and workload of astronauts and prolongs the execution time of space missions. Moreover, when the antenna module needs to be maintained or replaced, difficult disassembly operations may damage the equipment, further increasing costs and risks.

[0005] The space environment has characteristics such as high vacuum, strong radiation, and extreme temperature changes. Existing docking devices are difficult to adapt to these harsh conditions. When the temperature changes violently, the materials of the docking components may expand and contract thermally, resulting in a decrease in connection accuracy; strong radiation may also affect the performance of electronic components in the docking device and reduce its reliability. In addition, under different spacecraft mission requirements, the versatility and flexibility of docking devices are insufficient and cannot meet diverse docking requirements.

[0027] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] The present invention provides an unlockable passive docking device for an antenna module through improvement. The technical solution of the present invention is as follows:

[0029] As Figure 1 - Figure 6 shown, an unlockable passive docking device for an antenna module includes a housing 1. An inner wall of the housing 1 is provided with a barrel 2. Two symmetrically arranged straight slots 3 are formed on a surface of the barrel 2. Two symmetrically arranged circular holes 4 are formed on the surface of the barrel 2. A limiting ring 5 is fixedly connected to the surface of the barrel 2 by a fixing rod. An upper end of the barrel 2 is fixedly connected with a circular block 6. A first fixing hole 7 communicating with a surface of the circular block 6 is formed in an upper end of the circular block 6. A first fixing member 8 is arranged at the upper end of the circular block 6. A surface of the first fixing member 8 matches an inner wall of the first fixing hole 7. A through hole 9 is formed in the upper end of the circular block 6. A cylinder 10 is arranged on an inner wall of the through hole 9. A second fixing rod hole 11 communicating with a surface of the cylinder 10 is formed in an upper end of the cylinder 10. A second fixing member 12 is arranged at the upper end of the cylinder 10. A surface of the second fixing member 12 matches an inner wall of the second fixing rod hole 11. A lower end of the cylinder 10 is fixedly connected with a connecting component 13. A lower end of the connecting component 13 is fixedly connected with a disc 14.

[0030] Furthermore, a support column 15 is fixedly connected to the inner wall of the housing 1. A first spring 16 is fixedly connected to a surface of the support column 15. The other end of the first spring 16 is fixedly connected with a pressing block 17. The first spring 16 and the pressing block 17 constitute a buffer structure. During the docking process, if there is an external impact or a slight deviation in the position of the docking component, the first spring 16 can absorb part of the impact force through its own elastic deformation. The pressing block 17 can flexibly adjust its position under the action of the first spring 16 to provide stable support for the disc 14, avoiding damage to the disc 14 due to external impact, improving the adaptability and reliability of the docking device in a complex environment, and ensuring the smooth progress of the docking process.

[0031] Furthermore, a limiting block is fixedly connected to the inner wall of the barrel 2. The limiting block abuts against the surface of the extrusion block 17, and the upper end of the extrusion block 17 abuts against the lower end of the disc 14. The limiting block restricts the movement range of the extrusion block 17, so that when the extrusion block 17 provides support for the disc 14, excessive deviation or shaking will not occur. At the same time, the extrusion block 17 is in close contact with the disc 14, ensuring uniform force on the disc 14, further enhancing the stability of the docking structure, helping to maintain the relative position accuracy of each component during the docking process, improving the docking accuracy, and thus ensuring the stable operation of functions such as signal transmission after the space antenna module is docked.

[0032] Furthermore, there are two symmetrically arranged metal balls 18 in the outer shell 1. The metal balls 18 match the round holes 4. The cooperation between the metal balls 18 and the round holes 4 can play a role in positioning and locking. When the docking is completed, the metal balls 18 are embedded in the round holes 4, which can prevent relative rotation or displacement between the barrel 2 and the outer shell 1, making the connection of the entire docking device more firm, enhancing the stability and reliability of the docking structure, ensuring that the docking device can still maintain a good docking state under the complex external forces in the space environment, and guaranteeing the normal operation of the space antenna module.

[0033] Furthermore, a limiting ring 19 is arranged on the inner wall of the outer shell 1. The upper end of the limiting ring 19 is fixedly connected with a second spring 20. The upper end of the second spring 20 is fixedly connected with the inner wall of the outer shell 1. The second spring 20 and the limiting ring 19 work together to further enhance the buffering and positioning ability of the device. The second spring 20 can provide an upward elastic force for the limiting ring 19. When the device is subjected to external forces, it can absorb part of the energy through elastic deformation and play a buffering role. At the same time, the limiting ring 19 abuts against the limiting ring 5, restricting the axial movement range of the barrel 2, ensuring that the barrel 2 moves within a certain position range, helping to maintain the relative position stability between the components of the docking device, and improving the adaptability and reliability of the docking device under different working conditions.

[0034] Furthermore, a fixing groove 21 is formed on the surface of the outer shell 1, and a fixing ring plate 22 is arranged at the upper end of the outer shell 1. The fixing ring plate 22 matches the fixing groove 21. This structural design facilitates the installation and fixation of the entire docking device. In practical applications, the docking device can be quickly and accurately installed at the specified position by embedding the fixing ring plate 22 into the fixing groove 21, improving the installation efficiency. Moreover, the close cooperation between the fixing groove 21 and the fixing ring plate 22 can ensure that the docking device will not loosen or displace easily after installation, enhancing the overall stability of the device and providing a strong guarantee for the stable docking of the space antenna module.

[0035] Furthermore, the limiting ring 5 is located above the limiting circular ring 19. The lower end of the limiting ring 5 abuts against the upper end of the limiting circular ring 19. The limiting ring 5 and the limiting circular ring 19 cooperate with each other to accurately limit the position of the barrel 2 in the axial direction. Their abutment can effectively prevent the barrel 2 from moving up and down excessively, ensure that the barrel 2 is always in a proper position during the docking process, maintain the relative position accuracy between components, contribute to improving the accuracy and stability of docking, ensure that the space antenna module can work properly after docking, and avoid the problem of poor docking caused by the position deviation of the barrel 2.

[0036] Furthermore, docking heads 23 are slidably connected to the inner walls of the first fixing hole 7 and the second fixing rod hole 11. Two symmetrically arranged third limiting holes 24 are formed on the surface of the docking head 23. The inner walls of the first fixing hole 7 and the second fixing rod hole 11 are slidably connected to the docking head 23. This design makes the installation and disassembly of the docking head 23 easy and convenient. In the actual space operation scenario, the staff can quickly insert the docking head 23 into the corresponding holes to complete the preliminary positioning, greatly shortening the time required for docking and improving the operation efficiency. At the same time, the sliding connection method also allows the docking head 23 to fine-tune its position within a certain range to adapt to different docking environments and accuracy requirements, enhancing the flexibility of the docking operation.

[0037] Working principle: When docking the space antenna module, first insert the docking head 23 into the first fixing hole 7 and the second fixing rod hole 11. The third limiting holes 24 on the docking head 23 can be used for further cooperation and fixation with other components. During the insertion process, if an external force causes the disc 14 to move downward, the extrusion block 17 will support the disc 14 upward under the action of the first spring 16, playing a buffering and stabilizing role. At the same time, the limiting block on the inner wall of the barrel 2 restricts the position of the extrusion block 17 to prevent it from moving excessively. After docking is completed, the symmetrically arranged metal balls 18 in the housing 1 can cooperate with the circular holes 4 on the surface of the barrel 2 to further fix the docking state. If unlocking is required, apply a certain external force to overcome the elastic forces of the first spring 16 and the second spring 20, move the relevant components, and release the fixed state of the docking head 23 to complete the unlocking and separation operation. The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
