Description

Technical Field

[0001] The invention relates to the technical field of on-track assembly, and in particular to an on-track assembly auxiliary device for a spatial structure. Background Art

[0002] As human beings continue to explore space, more and more large-scale space structures are proposed and planned to be built. For example, the scale of space stations continues to expand, requiring on-orbit assembly of modules; the construction of large space telescopes also requires high-precision assembly operations. These complex space structures cannot be fully assembled on the ground and then launched, and must rely on on-orbit assembly technology. Therefore, various forms of on-orbit assembly auxiliary devices for space structures have emerged.

[0003] Existing auxiliary devices rely on the direct intervention of astronauts to plan and execute missions. Although the use of manual intervention can promote some progress in the on-orbit assembly of space structures to a certain extent, it is often dangerous and poses a high risk to astronauts. During the on-orbit assembly process, astronauts need to be exposed to the space environment for a long time and may face problems such as insufficient oxygen and cosmic radiation.

[0004] In summary, how to solve the problems of oxygen deficiency and cosmic radiation that may be faced by the existing technology using manual intervention has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose an on-orbit assembly auxiliary device for space structures. Summary of the invention

[0005] In order to solve the above problems, the present invention discloses an on-orbit assembly auxiliary device for a space structure, which reduces the dependence on manual operation through automated and intelligent control of a rotating motor, thereby reducing labor costs and risks brought by manual operation.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an auxiliary device for assembling a space structure on track, comprising a plurality of first connecting rods, each of which is hinged with a plurality of second connecting rods at one end, and each of the second connecting rods is provided with an opening and closing assembly for unfolding the second connecting rod. The opening and closing assembly comprises a plurality of first hinged rods and a third hinged rod, each of the second connecting rods is provided with a slide groove; each of the slide grooves is provided with a first slider and a second slider for sliding; each two adjacent first sliders are rotatably connected by a first hinged rod; each two adjacent second sliders are connected by a third hinged rod; wherein the first slider near the first connecting rod is rotatably connected with the first connecting rod by the first hinged rod. wherein the second connecting rod at the top is provided with a rotating assembly for providing a rotating force. the first connecting rods are detachably connected with the second connecting rods at the top of each layer by a quick release member; the bottom of the first connecting rods are detachably connected with a support rod by a clamping member. the bottom end of the support rod is rotatably matched with the second connecting rods at the top of each layer.

[0007] The technical principle of the above scheme is as follows: because a plurality of second connecting rods are hinged on the first connecting rod, and a rotating assembly for providing a rotating force is provided on the second connecting rod at the top, the second connecting rod can be extended or retracted by the rotating assembly at the top. Since the second connecting rods are provided with sliding grooves for the first slider and the second slider to move, every two adjacent first sliders are connected by a first hinge rod; every two adjacent second sliders are connected by a third hinge rod; so when the second connecting rod at the top extends outward, the second connecting rod at the middle part can be driven to extend in sequence by the first hinge rod and the third hinge rod. On the contrary, when the second connecting rod contracts inward, the second connecting rod at the middle part can be driven to contract toward the first connecting rod in sequence by the first hinge rod and the third hinge rod, so as to realize the opening and closing of the second connecting rod. The first connecting rod and the second connecting rod at the top of each layer can be connected or disassembled with each other by a quick release part, so as to form an annular structure or an annular structure formed by a plurality of fan-shaped detachable connections. A plurality of support rods can be detachably connected with each other by a clamping member, and in this way, a multi-layer support structure can be overlapped.

[0008] The above scheme has the following beneficial effects: 1. This solution provides driving force through the rotating assembly at the top, which can achieve the extension or contraction of the second connecting rod, thereby adjusting the spatial structure of the entire device. This design enables the device to flexibly respond to different space requirements during assembly and disassembly, thereby improving the flexibility and efficiency of the assembly process.

[0009] 2. In this solution, the first connecting rod and the second connecting rod are connected by the first hinge rod and the third hinge rod, and the first slider, the second slider and the slide groove are used to achieve rotational cooperation, thereby ensuring the stability and reliability of the structure. At the same time, the use of quick-release parts and clamping parts further enhances the connection strength of the structure, making the device more stable when bearing loads.

[0010] 3. In this scheme, the device can not only form a ring structure, but also form a ring structure or other complex structures composed of multiple fan-shaped detachable connections by adjusting the connection method of the quick-release parts and the clamping parts. This makes the device have a wide range of application prospects in the assembly and maintenance of space structures such as spacecraft and space stations.

[0011] Furthermore, the rotating assembly includes a rotating motor, which is electrically connected to a controller; the rotating motor is fixedly connected to the top of the second connecting rod, and the output shaft of the rotating motor is fixedly connected to the hinge of the second connecting rod at the top.

[0012] Beneficial effect: The rotating motor is fixedly installed above the second connecting rod at the top, and its output shaft is connected to the hinge of the second connecting rod. When the rotating motor is running, it will generate a rotational torque, thereby driving the second connecting rod at the top to expand or retract. The automation and intelligent control of the rotating motor can reduce the dependence on manual operation, reduce labor costs and risks brought by manual operation.

[0013] Furthermore, the quick-release parts include several rotating disks and bases, and the rotating disks are all rotatably matched with the bases; the bases are fixedly connected to the outer wall of the first connecting rod, and the rotating disks are installed on the outer side of the second connecting rod located at the top of each layer; the rotating disks are fixedly connected to cams, and the inner walls of the bases are provided with grooves for clamping the cams; the rotating disks are provided with rotating components for driving the rotating disks to rotate.

[0014] Beneficial effect: The rotating disk is driven to rotate by the rotating assembly. Since the rotating disk is fixedly connected with a cam, and the inner side wall of the base is provided with a slot matching the cam, when the cam rotates to the slot position in the base, the cam can be inserted into the slot, thereby realizing a tight connection between the rotating disk and the base. On the contrary, the rotating disk and the base can be quickly disassembled. In this way, the connection parts can be quickly disassembled and assembled, thereby further improving the assembly efficiency.

[0015] Furthermore, the rotating assembly includes a stepper motor, and the controller is used to control the operation of the stepper motor; the output shafts of the stepper motors are coaxially fixedly connected to the rotating disk, and the stepper motors are fixedly connected to the outer side wall of the second connecting rod at the top of each layer.

[0016] Beneficial effect: When the controller receives the control instruction, it sends an electric pulse signal to the stepper motor. The stepper motor rotates according to the received signal, and its output shaft drives the rotating disk to rotate synchronously; then further ensures the continuity and stability of power transmission, thereby ensuring the smooth progress of assembly work.

[0017] Furthermore, the clamping parts include a number of clamping plates arranged in a ring shape, the tops of the support rods are all opened with openings, the clamping plates are all located in the openings and slidingly cooperate with the openings; the clamping plates are all slidingly cooperated with the support rods, and the support rods are all fixedly connected to the bottom of the first connecting rod; the tops of the support rods are all threaded with nuts, and the clamping plates are all clamped with the outer ends of the openings and the nuts; the nuts are all provided with driving components for driving the nuts to rotate.

[0018] Beneficial effect: When the support rod needs to be fixed at the bottom of the first connecting rod, the support rod fixedly connected to the first connecting rod is placed in the clamping plate arranged in a ring, and the clamping plates are closed by tightening the nuts to clamp the support rod to fix it; conversely, the support rod can be released by loosening the nuts. The design of the clamping plate has strong adaptability and can adapt to clamping objects of different sizes, shapes and weights, so that the assembly auxiliary device can play an important role in various on-track assembly scenarios of space structures.

[0019] Furthermore, the driving assembly includes several driving motors, gears and racks. The driving motors are fixedly connected to the outside of the support rod, and the controller is used to control the operation of the driving motors; the output shafts of the driving motors are coaxially fixedly connected to the gears, and the gears are meshed with the racks; the racks are sleeved on the outside of the nuts.

[0020] Beneficial effect: The gear is driven by the driving motor to rotate, and the gear drives the meshing rack to rotate. Since the rack is sleeved on the outside of the nut, and the nut is threaded with the support rod, the nut can be driven by the rack to rotate on the outside of the support rod, so that the nut can clamp or loosen the clamping plate. By accurately controlling the operation of the driving motor, the position of the nut can be accurately adjusted, thereby ensuring that the clamping plate accurately clamps the clamping object.

[0021] Further, the annular diameter of the clamping plate located at the opening of the support rod is larger than the annular diameter of the clamping plate located inside the opening of the support rod.

[0022] Beneficial effect: Based on the principle of leverage and mechanical balance, when the clamping plate has a larger annular diameter at the opening of the support rod, the clamping force or supporting force it can provide will increase accordingly; this is because a larger diameter means a longer lever arm, thereby generating a greater torque under the same force, which helps to clamp or support the assembly object more firmly.

[0023] Furthermore, the second connecting rod is hinged with a second hinged rod at one end away from the rotating motor, adjacent second hinged rods are hinged to each other, and the second hinged rods close to the first connecting rod are hinged to the first connecting rod.

[0024] Beneficial effect: When the second connecting rod at the top extends outward, the second connecting rod in the middle is driven to extend in sequence through the first hinge rod. As the second connecting rod extends, the second hinge rod will also expand to form a stable structure. The design of the second hinge rod makes the structure more flexible when expanding and contracting, and the size and shape of the structure can be adjusted as needed.

[0025] Furthermore, the outer sides of the first connecting rod and the second connecting rod of each layer are detachably connected with vertical rods; and the inclined rods are detachably connected between the vertical rods and the supporting rods.

[0026] Beneficial effects: Through the design of the vertical rods and the inclined rods, a more stable frame structure can be formed, which helps to resist various forces and moments that may be encountered during the on-track assembly process, thereby improving the stability of the device.

[0027] Furthermore, the first connecting rod, the second connecting rod, the supporting rod, the vertical rod and the tilting rod are all manufactured by composite additive manufacturing, and the first hinged rod and the second hinged rod are both manufactured by shape memory material.

[0028] Beneficial effects: Composite materials have the advantages of light weight, high strength, and corrosion resistance, and are suitable for applications in space environments. Through additive manufacturing technology, these components can be directly manufactured in space, reducing launch costs and increasing design flexibility. Shape memory materials have unique recovery properties and can return to a pre-set shape at a specific temperature, which can further ensure the opening and closing of the structure, thereby improving stability.

Example

[0037] As attached Figure 1-Figure 5 As shown: an on-track assembly auxiliary device for a spatial structure includes a plurality of first connecting rods 1, one end of each of the first connecting rods 1 is hinged with a plurality of second connecting rods 2, and each of the second connecting rods 2 is provided with an opening and closing component for unfolding the second connecting rods 2.

[0038] The opening and closing assembly includes a plurality of first hinged rods 3 and a third hinged rod 19, each of the second connecting rods 2 is provided with a slide groove; a first slider 20 and a second slider 21 are slidably provided in each of the slide grooves; every two adjacent first sliders 20 are rotationally connected via a first hinged rod 3; every two adjacent second sliders 21 are connected via a third hinged rod 19; wherein the first slider 20 near the first connecting rod 1 is rotationally connected to the first connecting rod 1 via a first hinged rod 19; wherein a rotating assembly for providing a rotating force is provided on the second connecting rod 2 at the top.

[0039] like Figure 1 and Figure 5 As shown, the rotating assembly includes a rotating motor 6, which is electrically connected to a controller; the rotating motor 6 is bolted and fixedly connected to the top of the second connecting rod 2, and the output shaft of the rotating motor 6 is bolted and fixedly connected to the hinge of the second connecting rod 2 at the top. The rotating motor 6 is bolted and fixedly installed above the second connecting rod 2 at the top, and its output shaft is bolted and fixedly connected to the hinge of the second connecting rod 2. When the rotating motor 6 is running, it will generate a rotational torque, thereby driving the second connecting rod 2 at the top to expand or retract. The automated and intelligent control of the rotating motor 6 can reduce the reliance on manual operation, and can reduce labor costs and risks brought by manual operation.

[0040] like Figure 1 and Figure 2 As shown, the first connecting rod 1 is detachably connected to the second connecting rod 2 at the top of each layer through a quick-release part 22; the quick-release part 22 includes a plurality of rotating disks 7 and a base 8, and the rotating disks 7 are rotatably matched with the base 8; the base 8 is bolted and fixedly connected to the outer wall of the first connecting rod 1, and the rotating disk 7 is installed on the outer side of the second connecting rod 2 located at the top of each layer; the rotating disk 7 is bolted and fixedly connected with a cam 9, and the inner wall of the base 8 is provided with a groove for clamping the cam 9; the rotating disk 7 is provided with a rotating component for driving the rotating disk 7 to rotate.

[0041] The rotating assembly includes a stepper motor 10, and the controller is used to control the operation of the stepper motor 10; the output shaft of the stepper motor 10 is coaxially bolted to the rotating disk 7, and the stepper motor 10 is bolted to the outer wall of the second connecting rod 2 at the top of each layer.

[0042] When the controller receives the control command, it sends an electric pulse signal to the stepper motor 10. The stepper motor 10 rotates according to the received signal, and its output shaft drives the rotating disk 7 to rotate synchronously; then the continuity and stability of power transmission are further ensured, thereby ensuring the smooth progress of the assembly work. The rotating disk 7 is driven to rotate by the stepper motor 10. Since the rotating disk 7 is fixedly connected with a cam 9 by bolts, and the inner side wall of the base 8 is provided with a slot matching the cam 9, when the cam 9 rotates to the slot position in the base 8, the cam 9 can be inserted into the slot, thereby realizing the fast connection between the rotating disk 7 and the base 8. On the contrary, the rotating disk 7 and the base 8 can be quickly disassembled. In this way, the connection parts can be quickly disassembled and assembled, thereby further improving the assembly efficiency.

[0043] The bottom of the first connecting rod 1 is detachably connected to the supporting rod 5 through the clamping piece 23, and the bottom end of the supporting rod 5 is rotatably matched with the second connecting rod 2 at the top of each layer.

[0044] like Figure 3 As shown, the clamping member 23 includes a plurality of clamping plates 11 arranged in a ring shape, the top of the support rod 5 is provided with an opening, the clamping plates 11 are located in the opening and slidably cooperate with the opening; the clamping plates 11 are slidably cooperated with the support rod 12, and the support rod 12 is bolted and fixedly connected to the bottom of the first connecting rod 1; the top of the support rod 5 is threadedly cooperated with the nut 13, the clamping plates 11 are clamped with the outer end of the opening and the nut 13; the nut 13 is provided with a driving component for driving the nut 13 to rotate.

[0045] The driving assembly includes several driving motors 14, gears 15 and racks 16. The driving motors 14 are all bolted and fixedly connected to the outside of the support rod 5. The controller is used to control the operation of the driving motors 14. The output shafts of the driving motors 14 are all coaxially bolted and fixedly connected to the gears 15. The gears 15 are all meshed with the racks 16. The racks 16 are all sleeved on the outside of the nuts 13.

[0046] The gear 15 is driven to rotate by the driving motor 14, and the gear 15 drives the meshing rack 16 to rotate. Since the rack 16 is sleeved on the outside of the nut 13, and the nut 13 is threadedly matched with the support rod 5, the nut 13 can be driven to rotate on the outside of the support rod 5 by the rack 16, so that the nut 13 can clamp or loosen the clamping plate 11. By accurately controlling the operation of the driving motor 14, the position of the nut 13 can be accurately adjusted, thereby ensuring that the clamping plate 11 accurately clamps the clamped object.

[0047] When the support rod 5 needs to be fixed at the bottom of the first connecting rod 1, the support rod 12 connected by bolts to the first connecting rod 1 is placed in the clamping plate 11 arranged in a ring shape, and the clamping plates 11 are closed by tightening the nuts 13, thereby clamping the support rod 12 to fix it; conversely, the support rod 12 can be released by loosening the nuts 13. The design of the clamping plate 11 has strong adaptability and can adapt to clamping objects of different sizes, shapes and weights, so that the assembly auxiliary device can play an important role in various on-track assembly scenarios of spatial structures.

[0048] The specific implementation process is as follows: because a plurality of second links 2 are hinged on the first link 1, and a rotating motor 6 is fixedly connected to the second link 2 at the top by bolts, the second link 2 can be extended or retracted by the rotating motor 6 at the top. Since the second link 2 is provided with a slide slot for the first slider 20 and the second slider 21 to move, every two adjacent first sliders 20 are connected by the first hinge rod 3; every two adjacent second sliders 21 are connected by the third hinge rod 19; therefore, when the second link 2 at the top is extended outward, the second link 2 in the middle can be driven to extend in sequence by the first hinge rod 3 and the third hinge rod 19. On the contrary, when the second link 2 is retracted inward, the second link 2 in the middle can be driven to retract toward the first link 1 in sequence by the first hinge rod 3 and the third hinge rod 19, so as to realize the opening and closing of the second link 2.

[0049] by Figure 1 For example, when the rotating motor 6 drives the second connecting rod 2 at the top to rotate to the right, the second connecting rod 2 can drive the first hinge rod 3 and the third hinge rod 19 to extend in sequence, so that the structure can expand; conversely, when the rotating motor 6 drives the second connecting rod 2 at the top to move to the left, the structure can be contracted. Thereby adjusting the spatial structure of the entire device. This design enables the device to flexibly respond to different space requirements during assembly and disassembly, improving the flexibility and efficiency of the assembly process. Through the design of the folding structure, it can occupy less space during the launch phase, thereby reducing the launch cost.

[0050] The first connecting rod 1 and the second connecting rod 2 at the top of each layer can be connected or disassembled through the base 8 and the rotating disk 7. According to the task requirements, multiple second connecting rods 2 or multiple fan-shaped structures can be spliced ​​into a large ring structure to meet various application scenarios such as space station maintenance, expansion, antenna array deployment, etc. The clamping plate 11 can be used to detachably connect a number of support rods 5 to each other, and in this way, multiple layers of support structures can be overlapped. Various complex space structures can be built, such as multi-layer platforms, three-dimensional frames, retractable antenna brackets, etc., to expand the application range of space structures. Example

[0051] As attached Figure 3As shown, the difference from the above is that the annular diameter of the clamping plate 11 located at the opening of the support rod 5 is larger than the annular diameter of the clamping plate 11 located inside the opening of the support rod 5.

[0052] The specific implementation process is as follows: Based on the principle of leverage and the principle of mechanical balance, when the clamping plate 11 has a larger annular diameter at the opening of the support rod 5, the clamping force or supporting force it can provide will increase accordingly; this is because a larger diameter means a longer lever arm, thereby generating a greater torque under the same force, which helps to clamp or support the assembly object more securely. Example

[0053] As attached Figure 1 As shown, the difference from the above is that the second connecting rod 2 is hinged with a second hinged rod 4 at one end away from the rotating motor 6, adjacent second hinged rods 4 are hinged to each other, and the second hinged rods 4 close to the first connecting rod 1 are hinged to the first connecting rod 1.

[0054] The specific implementation process is as follows: when the second connecting rod 2 at the top extends outward, the second connecting rod 2 at the middle part is driven to extend in sequence through the first hinge rod 3. As the second connecting rod 2 extends, the second hinge rod 4 will also expand accordingly to form a stable structure. The design of the second hinge rod 4 makes the structure more flexible when expanding and contracting, and the size and shape of the structure can be adjusted as needed. Example

[0055] As attached Figure 1 As shown, the difference from the above is that the outer sides of the first connecting rod 1 and the second connecting rod 2 of each layer are detachably connected with the vertical rod 17; and the vertical rod 17 and the supporting rod 5 are detachably connected with the inclined rod 18.

[0056] The specific implementation process is as follows: through the design of the vertical rod 17 and the inclined rod 18, the detachable snap-fit ​​connection mode can be achieved by the quick release member 22 and the clamping member 23, and the quick release member 22 and the clamping member 23 can be installed at the corresponding positions respectively. It has strong applicability and can form a more stable frame structure, which helps to resist various forces and moments that may be encountered during the on-track assembly process, thereby improving the stability of the device. Example

[0057] As attached Figure 1-Figure 4 As shown, the difference from the above is that the first connecting rod 1, the second connecting rod 2, the supporting rod 5, the vertical rod 17 and the tilting rod 18 are all made of composite material additive manufacturing, and the first hinged rod 3 and the second hinged rod 4 are both made of shape memory material.

[0058] The specific implementation process is as follows: Composite materials have the advantages of light weight, high strength, and corrosion resistance, and are suitable for applications in space environments. Through additive manufacturing technology, these components can be directly manufactured in space, reducing launch costs and increasing design flexibility. Shape memory materials have unique recovery properties and can return to a pre-set shape at a specific temperature, which can further ensure the opening and closing of the structure, thereby improving stability.

[0059] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
