Description

Technical Field

[0001] This disclosure relates to the field of space protection technology, and more specifically, to a protective device for complex curved surfaces outside a space station. Background Technology

[0002] With the increasing amount of space debris, the issue of extending the lifespan of spacecraft in orbit is becoming increasingly serious. Cables on the surface of the space station are frequently subjected to impacts from micrometeoroids and space debris. To address this, my country's space station has implemented space physical protection measures for components such as the module structure, external pipelines, and equipment cables to reduce damage to cables from space debris impacts. The cable protection areas are diverse, and the protection of irregularly shaped three-dimensional space cables, especially those between modules and near surface equipment, is relatively more challenging.

[0003] According to the literature "Research on Space Station Debris Protection Technology," internationally, whipple structures are commonly used to intercept debris. This method primarily utilizes the gradual dissipation of kinetic energy from the impact of space debris against the double protective layers. However, this approach is only suitable for protecting regular cabin surfaces and is not ideal for irregularly shaped surfaces. Furthermore, it cannot meet the requirements for astronauts' on-orbit operations.

[0048] To make the objectives, technical solutions, and advantages of this disclosure clearer, the disclosure will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0054] It should be noted that any symbols and / or numbers present in the specification that are not marked in the accompanying drawings are not reference numerals.

[0055] The optional embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0056] like Figure 1 As shown, this disclosure provides a protective device for complex curved surfaces outside a space station, including: a protective structure 1, a folding arm assembly 2, a main tube assembly 3, and a telescopic arm assembly 4.

[0057] The folding arm assembly 2, one end of which is rotatably connected to one end of the main assembly 3, includes multiple locking components that respectively engage with multiple first mounting holes on the space station module. The folding arm assembly 2 has an unfolded shape (e.g., Figure 1 As shown), and the folded storage form (as shown). Figure 2 (As shown).

[0058] For example, the main component 3 is a square tube. The square tube provides a mechanical interface on which the protective structure 1 is mounted, expanding the installation area of ​​the protective structure 1 and making it more adaptable to the irregular shape of the protective structure 1 with its complex cable layout in the cabin.

[0059] Because astronauts are enormous when wearing spacesuits, a large area needs to be protected outside the space station. Fully unfolded protective gear is inconvenient for astronauts to carry outside the spacecraft. Therefore, a foldable design was incorporated into the protective gear, reducing its overall size and facilitating its transport outside the spacecraft by astronauts. It can then be unfolded for operation. Furthermore, the folding arm assembly 2 has a conformal shape, allowing the protective gear to fit snugly against the shape of the space station's modules after unfolding, providing excellent protection.

[0060] The locking components (such as locking handwheels) on the folding arm assembly 2 can be quickly connected to the first mounting hole on the space station module, simplifying the astronauts' operation steps outside the cabin and avoiding inconvenience in operation outside the cabin.

[0061] The telescopic arm assembly 4 has one end fixedly connected to the other end of the main tube assembly 3, and includes a clamping seat assembly 43 that mates with the second mounting hole of the cabin plate. The telescopic arm assembly 4, the main tube assembly 3, and the unfolded folding arm assembly 2 are configured to form an auxiliary structure.

[0062] The telescopic arm assembly 4 allows for control of the length of the protective device, solving the problem of deformed panels or protective devices that cannot be properly installed after prolonged exposure to space, effectively supporting the needs of astronauts working on the space station for extended periods.

[0063] The telescopic arm assembly 4, together with the main tube assembly 3 and the unfolded folding arm assembly 2, forms an auxiliary structure, which is then connected to the equipment and the cabin, respectively. This ensures that the protective device conforms to the shape of the space station's cabin panels, providing excellent protection. The three-point connection method enhances the structure's stability.

[0064] like Figure 5 As shown, the clamping seat assembly 43 on the telescopic arm assembly 4 can be quickly connected to the second mounting hole on the space station module, simplifying the astronauts' operation steps outside the cabin, avoiding the inconvenience of operation outside the cabin, and enabling the protective device to be quickly installed as a whole.

[0065] The protective structure 1 is detachably connected to the main pipe assembly 3 and the telescopic arm assembly 4. This allows the protective structure 1 to be easily removed and stored inside the cabin, thus reducing the space it occupies within the cabin.

[0066] In some specific embodiments, the folding arm assembly 2 further includes a rigid or semi-rigid folding arm, and the plurality of locking members are fixedly connected to the folding arm.

[0067] Rigid or semi-rigid folding arms allow astronauts to quickly install them after exiting the spacecraft, avoiding the disadvantages of flexible materials being unshapen in space. Semi-rigid folding arms allow protective devices to better adapt to and fit changes in the cabin panels.

[0068] In some specific embodiments, such as Figure 3 As shown, the locking component includes: a locking knob 21 (such as a locking handwheel), a central shaft 22, a cavity 23, a latch seat 24, and a latching element 25.

[0069] The cavity 23 is fixedly connected to the latch seat 24. The cavity 23 includes a first gear disk 26, a second gear disk 27, and a locking spring 28. The contact surfaces of the first gear disk 26 and the second gear disk 27 can mesh with each other. The non-contact surface of the first gear disk 26 is fixedly connected to the first inner wall of the cavity 23. The non-contact surface of the second gear disk 27 is elastically connected to one end of the locking spring 28. The other end of the locking spring 28 is fixedly connected to the second inner wall of the cavity 23. The first inner wall and the second inner wall are opposing inner walls.

[0070] The combination of the first gear disk 26 and the second gear disk 27 acts as a damper, reducing the loosening of the locking mechanism. The locking spring 28 provides an opposing force to the first gear disk 26 and the second gear disk 27, further enhancing the locking effect of the first gear disk 26 and the second gear disk 27 on the central shaft 22.

[0071] The locking knob 21 is fixedly connected to one end of the central shaft 22.

[0072] The central shaft 22 passes sequentially through the first gear disk 26, the second gear disk 27 and the locking spring 28 of the cavity 23, is movably connected to the buckle seat 24, and is threadedly connected to the first gear disk 26 and the second gear disk 27.

[0073] The central shaft 22 can be screwed in and out by adjusting the distance relative to the latch seat 24 via a thread.

[0074] The fastener 25 is disposed at the other end of the fastener seat 24 and is pressed and connected to the other end of the central shaft 22 inside the fastener seat 24. The fastener 25 has a semi-exposed state when the central shaft 22 is screwed in and a hidden state when the central shaft 22 is screwed out.

[0075] When the latch 25 is in a semi-exposed state, it locks with the first mounting hole on the hatch plate, preventing the protective device from falling off during operation; when the latch 25 is in a concealed state, it disengages from the first mounting hole on the hatch plate, allowing the protective device to be easily removed.

[0076] In some specific embodiments, such as Figure 4 As shown, the central shaft 22 includes a bead-receiving inclined surface 221 and a bead-receiving groove 222. The fastening member 25 includes a steel ball. The steel ball has a semi-exposed state when the central shaft 22 is screwed in, where it moves from the bead-receiving groove 222 along the bead-receiving inclined surface 221 to the shaft of the central shaft 22, and a hidden state when the central shaft 22 is screwed out, where it falls back into the bead-receiving groove 222 along the bead-receiving inclined surface 221.

[0077] Preferably, the angle between the bead-receiving inclined surface 221 and the axis of the central axis 22 is in the range of 20° to 35°. However, this disclosure is not limited to this. The bead-receiving inclined surface 221 is subjected to, but is not limited to, carburizing treatment to improve surface hardness and ensure the service life of the bead-receiving inclined surface 221.

[0078] In this specific embodiment, the locking of the protective device to the cabin panel is easily achieved by rotating the central shaft 22 in and out, which not only ensures the stability of the lock but also improves the convenience of extravehicular operations for astronauts.

[0079] In some specific embodiments, the locking knob 21 is off-axis fixed to the central shaft 22.

[0080] The locking knob 21 is connected to the central shaft 22 via a flat shaft structure. By lengthening the lever arm, the ease of operation of the locking knob 21 is improved.

[0081] In some specific embodiments, such as Figure 5 As shown, the telescopic arm assembly 4 also includes an adapter frame 41 and a telescopic seat assembly 42.

[0082] The adapter 41 is detachably connected at one end to the main tube assembly 3 and detachably connected at the other end to one end of the telescopic seat assembly 42.

[0083] The other end of the telescopic seat assembly 42 is fixedly connected to the clamping seat assembly 43.

[0084] The clamping seat assembly 43, the adapter frame 41, and the telescopic seat assembly 42 constitute the telescopic arm assembly 4.

[0085] The adapter 41 is an irregularly shaped structure with one end interface matching the direction and position of the main component 3, and the other end interface matching the position and direction of the other end interface of the cabin plate.

[0086] In some specific embodiments, such as Figure 6 As shown, the telescopic seat assembly 42 includes: a telescopic outer shell 421, a telescopic rod 422, a locking tongue 423, a cam seat 424, a cam paddle 425, and a telescopic spring 426.

[0087] The telescopic housing 421 includes a main housing and a branch housing that are fixedly connected. For example, the branch housing is vertically fixed to the main housing so that the locking tongue 423 can more securely lock the telescopic rod 422.

[0088] The first end of the main outer shell is detachably connected to the adapter frame 41. This facilitates the removal and storage of the protective structure 1 inside the cabin, thereby reducing its space occupation within the cabin.

[0089] The telescopic rod 422 passes through the main housing and includes multiple locking holes. These locking holes facilitate the insertion of the locking tongue 423 to lock the length of the protective device and restrict the telescopic movement of the telescopic rod 422.

[0090] One end of the branch housing is fixedly connected to the cam seat 424.

[0091] The cam seat 424 is rotatably connected to the cam paddle 425.

[0092] The latch 423 passes through the branch housing and the cam seat 424. The first end of the latch 423 is connected to the cam paddle 425, and the second end of the latch 423 can be sleeved with the locking hole.

[0093] The cam lever 425 can rotate around the eccentric shaft. By changing the contact area between the cam surface and the telescopic housing 421, the distance between the eccentric shaft and the telescopic housing 421 can be adjusted, thereby realizing the telescopic movement of the latch 423.

[0094] One end of the telescopic spring 426 is fixedly connected to the cam seat 424, and the other end is elastically connected to the latch 423, so as to realize the automatic telescopic movement of the latch 423.

[0095] In some specific embodiments, such as Figure 6 As shown, the clamping seat assembly 43 includes: a clamping seat 431, a screw 432, a clamping handwheel 433, a clamping pad 434, a clamping lever 435, and a torsion spring 436.

[0096] The clamping seat 431 is fixedly connected to the second end of the main housing.

[0097] The screw 432 is perpendicularly inserted through the side wall of the clamping seat 431 and is threadedly connected to the side wall of the clamping seat 431. One end of the screw 432 is fixedly connected to the clamping handwheel 433, and the other end of the screw 432 is provided with a clamping pad 434. The clamping pad 434 and the side wall form a clamping layer.

[0098] The clamping paddle 435 is rotatably connected to the clamping seat 431, and the rotation direction of the clamping paddle 435 is perpendicular to the clamping layer. One end of the torsion spring 436 is fixedly connected to the side wall of the clamping seat 431, and the other end of the torsion spring 436 is elastically connected to the clamping paddle 435.

[0099] In this specific embodiment, the distance between the screw 432 and the side wall of the clamping seat 431 can be adjusted by rotating the clamping handwheel 433. The bottom end of the screw 432 is equipped with the clamping pad 434, which has a certain elasticity and can adapt to the cabin plate structure of different thicknesses. The clamping lever 435 can be pressed against the clamping cabin plate by the torsion spring 436 to prevent the clamping seat assembly 43 from drifting away during installation.

[0100] In some specific embodiments, one edge of the protective structure 1 is detachably connected to the main tube assembly 3 and the telescopic arm assembly 4.

[0101] The protective structure 1 is designed for easy removal and storage inside the cabin, minimizing its space occupation. One edge of the protective structure 1 connects to the main control assembly 3 and the telescopic arm assembly 4, allowing for easy deployment of the protective structure and preventing the telescopic arm assembly 4, the main control assembly 3, and the folding arm assembly 2 from interfering with astronaut operations.

[0102] In some specific embodiments, such as Figure 1 As shown, the protective structure 1 includes an upper protective structure 1 and a lower protective structure 1. The upper protective structure 1 and the lower protective structure 1 are detachably connected by overlapping edges.

[0103] The upper protective structure 1 and the lower protective structure 1 overlap at the edges to achieve protection of the maximum protection area for debris.

[0104] The protective device described in this embodiment includes a protective structure, a folding arm assembly, a main pipe assembly, and a telescopic arm assembly. The folding arm assembly has an extended form when unfolded and a folded form when folded, reducing the overall outer size of the protective device and facilitating extravehicular activity (EVA) transport for astronauts. The telescopic arm assembly, together with the main pipe assembly and the unfolded folding arm assembly, forms an extended structure, which is connected to the equipment and the cabin body, respectively, ensuring the protective device conforms to the shape of the space station's cabin panels and provides effective protection. The three-point connection method improves the structure's stability and reduces installation difficulty. The protective structure is detachably connected to the main pipe assembly and the telescopic arm assembly. This facilitates the removal and storage of the protective structure inside the cabin, reducing its space occupation. The telescopic arm assembly reduces the overall length of the protective device during EVA, improving the flexibility of the external protection area and enhancing the device's adaptability to deformation in the clamping areas of the cabin body. The three-point connection points are distributed throughout the cabin, reducing installation difficulty.

[0105] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0106] The above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit it. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
