Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of on-orbit assembly, in particular to an on-orbit assembly auxiliary device for space structure. BACKGROUND

[0002] With the deepening of human space exploration, more and more large space structures are proposed and planned to be built. For example, the scale of space stations is continuously expanding, which requires on-orbit assembly of modules; the construction of large space telescopes also requires high-precision assembly operations. These complex space structures cannot be completely assembled on the ground before launch and must rely on on-orbit assembly technology to achieve. Therefore, various forms of on-orbit assembly auxiliary devices for space structures have emerged.

[0003] The existing auxiliary devices rely on direct intervention of astronauts to plan and execute tasks. Although the manual intervention method can promote the on-orbit assembly of space structures to some extent, it is often dangerous and poses a high risk to astronauts. During the execution of on-orbit assembly, astronauts need to be exposed to space environment for a long time and may face problems such as oxygen deficiency and cosmic radiation.

[0004] In summary, how to solve the problem that the existing technology uses manual intervention method and may face problems such as oxygen deficiency and cosmic radiation has become a difficult problem that needs to be solved in the field at present. Therefore, it is necessary to propose an on-orbit assembly auxiliary device for space structure. SUMMARY

[0005] To solve the above problems, the present application discloses an on-orbit assembly auxiliary device for space structure, which reduces the dependence on manual operation through automatic and intelligent control of the rotating motor, thereby reducing labor costs and risks caused by manual operation.

[0006] In order to achieve the above purpose, the technical scheme of the present application is as follows: an on-orbit assembly auxiliary device for space structure, comprising a plurality of first connecting rods, each first connecting rod being hingedly connected with a plurality of second connecting rods at one end, and each second connecting rod being 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 third hinged rods, and each second connecting rod is provided with a sliding groove; each sliding groove is slidably provided with a first sliding block and a second sliding block; each two adjacent first sliding blocks are connected by a first hinged rod; each two adjacent second sliding blocks are connected by a third hinged rod; and the first sliding block near the first connecting rod is connected with the first connecting rod by a first hinged rod. The second connecting rod at the top end is provided with a rotating assembly for providing rotating force. The first connecting rod is detachably connected with the second connecting rod at the top of each layer by a quick release member; and the first connecting rod at the bottom is detachably connected with a support rod by a clamping member. The bottom end of the support rod is rotatably connected with the second connecting rod at the top of each layer.

[0007] The technical principle of the above scheme is as follows: because the first connecting rod is hinged with a plurality of second connecting rods, the second connecting rod at the top end is provided with a rotating assembly for providing rotating force, so that the second connecting rod can be stretched or contracted through the rotating assembly at the top. Since the second connecting rod is provided with a sliding groove for the movement of the first slider and the second slider, every two adjacent first sliders are connected through the first hinge rod, and every two adjacent second sliders are connected through the third hinge rod, so that when the second connecting rod at the top is stretched outward, the second connecting rods at the middle part can be sequentially driven to stretch out through the first hinge rod and the third hinge rod. Conversely, when the second connecting rod is contracted inward, the second connecting rods at the middle part can be sequentially driven to contract toward the first connecting rod through the first hinge rod and the third hinge rod, so as to realize the opening and closing of the second connecting rod. The quick release member can connect or disassemble the first connecting rod and the second connecting rod at the top of each layer, so as to form a ring structure or a ring structure formed by a plurality of detachable fan-shaped structures. The clamping member can detachably connect a plurality of support rods, so as to form a multi-layer support structure.

[0008] The above scheme has the following beneficial effects:

[0009] 1、The rotating assembly at the top provides driving force, which can realize the stretching or contraction of the second connecting rod, so as to adjust the spatial structure of the whole device. This design makes the device flexible in assembly and disassembly process to meet different space requirements, improves the flexibility and efficiency of the assembly process.

[0010] 2、The first connecting rod and the second connecting rod are connected through the first hinge rod and the third hinge rod, and the rotating cooperation is realized through the first slider, the second slider and the sliding groove, which ensures the stability and reliability of the structure. At the same time, the use of quick release member and clamping member further enhances the connection strength of the structure, so that the device is more stable when bearing load.

[0011] 3、The device not only can form a ring structure, but also can form a ring structure or other complex structure formed by a plurality of detachable fan-shaped structures by adjusting the connection mode of the quick release member and the clamping member. The device has wide application prospect in the assembly and maintenance of space structures such as spacecraft and space station.

[0012] Further, the rotating assembly includes a rotating motor, the rotating motor is electrically connected with a controller; the rotating motor is fixedly connected above the second connecting rod at the top end, and the output shaft of the rotating motor is fixedly connected with the hinge of the second connecting rod at the top end.

[0013] Beneficial effects: the second connecting rod is fixedly installed on the top end of the rotating motor, and the output shaft of the rotating motor is connected to the hinge of the second connecting rod. When the rotating motor operates, it will generate a rotating torque to drive the second connecting rod at the top to expand or contract. The automation and intelligent control of the rotating motor can reduce the dependence on manual operation, reduce labor costs and the risks brought by manual operation.

[0014] Further, the quick release assembly includes a plurality of rotating discs and bases, the rotating discs are in rotating cooperation with the bases, the bases are fixedly connected to the outer side walls of the first connecting rods, the rotating discs are installed on the outer sides of the second connecting rods at the top of each layer, the cams are fixedly connected to the rotating discs, the inner side walls of the bases are provided with clamping grooves for clamping the cams, and the rotating discs are provided with rotating components for driving the rotating discs to rotate.

[0015] Beneficial effects: the rotating discs are driven by the rotating components to rotate, and since the rotating discs are fixedly connected with the cams and the inner side walls of the bases are provided with clamping grooves matched with the cams, the cams can be clamped into the clamping grooves when the cams rotate to the positions of the clamping grooves in the bases, so as to realize the fastening connection between the rotating discs and the bases. Conversely, the rotating discs and the bases can be quickly disassembled. In this way, the quick assembly and disassembly of the connecting parts are realized, so as to further improve the assembly efficiency.

[0016] Further, the rotating components include stepping motors, and the controller is used to control the operation of the stepping motors; the output shafts of the stepping motors are coaxially fixedly connected with the rotating discs, and the stepping motors are fixedly connected to the outer side walls of the second connecting rods at the top of each layer.

[0017] Beneficial effects: when the controller receives a control instruction, it sends an electric pulse signal to the stepping motor, and the stepping motor rotates according to the received signal, and the output shaft of the stepping motor drives the rotating disc to rotate synchronously; then the continuity and stability of power transmission are further ensured, so as to ensure the smooth progress of the assembly work.

[0018] Further, the clamping member includes a plurality of annularly arranged clamping plates, the support rods are provided with openings at the top, the clamping plates are located in the openings and are in sliding cooperation with the openings, the clamping plates are in sliding cooperation with the support rods, the support rods are fixedly connected to the first connecting rod at the bottom, the support rods at the top are in threaded cooperation with nuts, the clamping plates are in clamping cooperation with the outer side ends of the openings and the nuts, and the nuts are provided with driving components for driving the nuts to rotate.

[0019] Beneficial effects: when it is necessary to fix the support rods at the bottom of the first connecting rod, the support rods fixedly connected to the first connecting rod are placed in the annularly arranged clamping plates, the nuts are screwed, the clamping plates are closed to each other, the support rods are clamped to be fixed; conversely, the support rods can be released by unscrewing the nuts. The clamping plates have 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 space structure on-orbit assembly scenes.

[0020] Further, the driving assembly includes several driving motors, gears and racks, the driving motors are fixedly connected to the outer side of the support rod, and the controller is used for controlling the operation of the driving motors; the output shafts of the driving motors are coaxially fixedly connected with the gears, and the gears are mutually engaged with the racks; the racks are sleeved on the outer side of the nuts.

[0021] Beneficial effects: the driving motor drives the gear to rotate, and the gear drives the rack engaged therewith to rotate; since the rack is sleeved on the outer side of the nut, and the nut is threadedly matched with the support rod, the nut can be driven by the rack to rotate on the outer side 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 the accurate clamping of the clamping plate on the clamped object.

[0022] Further, the annular diameter of the clamping plate located at the opening of the support rod is greater than the annular diameter of the clamping plate located inside the opening of the support rod.

[0023] Beneficial effects: based on the principle of lever and the principle of mechanical equilibrium, 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 force arm, thereby generating a larger torque under the same force, which helps to more stably clamp or support the assembled object.

[0024] Further, the second connecting rods distal from the rotating motor are each hingedly connected with a second hinge rod, adjacent second hinge rods are hingedly connected with each other, and the second hinge rods close to the first connecting rods are each hingedly connected with the first connecting rods.

[0025] Beneficial effects: when the top second connecting rods stretch outward, the middle second connecting rods are sequentially driven to stretch by the first hinge rods, and as the second connecting rods stretch, the second hinge rods also expand, forming a stable structure. Through the design of the second hinge rods, the structure is more flexible when expanding and contracting, and the size and shape of the structure can be adjusted as needed.

[0026] Further, vertical rods are detachably connected to the outer sides of each layer of first connecting rods and second connecting rods; and inclined rods are detachably connected between the vertical rods and the support rods.

[0027] 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 torques that may be encountered during on-orbit assembly, thereby improving the stability of the device.

[0028] Further, the first connecting rods, the second connecting rods, the support rods, the vertical rods and the inclined rods are made of composite materials by additive manufacturing, and the first hinge rods and the second hinge rods are made of shape memory materials.

[0029] Beneficial effects: the composite material has the advantages of light weight, high strength, corrosion resistance and the like, and is suitable for application in a space environment. Through an additive manufacturing technology, the components can be directly manufactured in the space, thereby reducing launch cost and improving design flexibility. The shape memory material has unique recovery characteristics, can recover to a pre-set shape at a specific temperature, and can further ensure opening and closing of the structure, thereby improving stability.

[0030] Additional aspects and advantages of the present application will be in part apparent and in part pointed out hereinafter in the description. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0038] The present application will be further clarified by the following examples, which should not be construed as limiting the scope of the present application. It should be noted that the terms "front", "back", "left", "right", "upper" and "lower" as used in the following description refer to directions in the drawings and the terms "inner" and "outer" refer to directions towards or away from the geometric center of the specified member. EMBODIMENT ​

[0039] As attached Figures 1-5 As shown: A spatial structure on-track assembly auxiliary device 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.

[0040] The opening and closing assembly includes several first hinged rods 3 and third hinged rods 19, and each second connecting rod 2 is provided with a sliding groove; a first slider 20 and a second slider 21 are slidingly provided in each of the sliding grooves; every two adjacent first sliders 20 are rotationally connected through the first hinged rod 3; every two adjacent second sliders 21 are connected through the third hinged rod 19; the first slider 20 near the first connecting rod 1 is rotationally connected to the first connecting rod 1 through the first hinged rod 19; and a rotating assembly for providing rotational force is provided on the second connecting rod 2 at the top.

[0041] 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 to the top of the second connecting rod 2, and its output shaft is bolted to the hinge of the second connecting rod 2. The rotating motor 6 is bolted to the top of the second connecting rod 2, and its output shaft is bolted to the hinge of the second connecting rod 2. When the rotating motor 6 is running, it generates 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 reduces reliance on manual operation, thereby reducing labor costs and the risks associated with manual operation.

[0042] 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 fixedly connected to the outer wall of the first connecting rod 1 with bolts, and the rotating disks 7 are installed on the outer side of the second connecting rod 2 at the top of each layer; the rotating disk 7 is fixedly connected with a cam 9 with bolts, and the inner wall of the base 8 is provided with a slot for clamping the cam 9; the rotating disk 7 is provided with a rotating component for driving the rotating disk 7 to rotate.

[0043] The rotating assembly includes a stepper motor 10, and the controller is used to control the operation of the stepper motor 10; the output shafts of the stepper motor 10 are coaxially bolted to the rotating disk 7, and the stepper motors 10 are bolted to the outer wall of the second connecting rod 2 at the top of each layer.

[0044] 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. This further ensures the continuity and stability of power transmission, 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 wall of the base 8 is provided with a slot that matches the cam 9, when the cam 9 rotates to the slot position in the base 8, the cam 9 can be snapped into the slot, thereby achieving a tight 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.

[0045] The bottom of the first connecting rod 1 is detachably connected to the support rod 5 through the clamping piece 23, and the bottom end of the support rod 5 is rotatably matched with the second connecting rod 2 at the top of each layer.

[0046] 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 slide with the opening; the clamping plates 11 are slidably fitted 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 fitted with a nut 13, and 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.

[0047] The drive assembly includes several drive motors 14, gears 15 and racks 16. The drive motors 14 are all bolted to the outside of the support rod 5, and the controller is used to control the operation of the drive motors 14; the output shafts of the drive motors 14 are all coaxially bolted to the gears 15, and the gears 15 are all meshed with the racks 16; the racks 16 are all sleeved on the outside of the nuts 13.

[0048] The drive motor 14 drives the gear 15 to rotate, which in turn 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 engaged with the support rod 5, the rack 16 can drive the nut 13 to rotate outside the support rod 5, thereby allowing the nut 13 to tighten or loosen the clamping plate 11. By precisely controlling the operation of the drive motor 14, the position of the nut 13 can be accurately adjusted, thereby ensuring that the clamping plate 11 accurately clamps the clamped object.

[0049] When the support rod 5 needs to be secured to the bottom of the first connecting rod 1, the support rod 12, which is bolted to the first connecting rod 1, is placed in the annular clamping plates 11. Nuts 13 are tightened to close the clamping plates 11, thereby clamping the support rod 12 and securing it. Conversely, the support rod 12 can be released by loosening the nuts 13. The design of the clamping plates 11 is highly adaptable and can accommodate objects of varying sizes, shapes, and weights, making the assembly aid device useful in a variety of on-track spatial structure assembly scenarios.

[0050] The specific implementation process is as follows: Because several second links 2 are hingedly connected to the first link 1, and a rotary motor 6 is bolted to the top second link 2, the top rotary motor 6 can be used to extend or retract the second links 2. Since each second link 2 has a slot for the first and second sliders 20, 21 to move, each pair of adjacent first sliders 20 are pivotally connected by a first hinge rod 3, and each pair of adjacent second sliders 21 are connected by a third hinge rod 19. Therefore, when the top second link 2 extends outward, the first and third hinge rods 3 and 19 can sequentially drive the middle second links 2 to extend. Conversely, when the second link 2 retracts inward, the first and third hinge rods 3 and 19 can drive the middle second links 2 to retract toward the first link 1, thereby achieving the opening and closing of the second link 2.

[0051] by Figure 1 For example, when the 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, allowing the structure to expand. Conversely, when the motor 6 drives the second connecting rod 2 at the top to move to the left, the structure can be contracted. This adjusts the spatial structure of the entire device. This design allows the device to flexibly respond to different space requirements during assembly and disassembly, improving the flexibility and efficiency of the assembly process. The foldable structure design can occupy less space during the launch phase, thereby reducing launch costs.

[0052] The base 8 and rotating disk 7 allow the first connecting rod 1 and the second connecting rod 2 at the top of each layer to be connected or disconnected. Multiple second connecting rods 2 or multiple fan-shaped structures can be assembled into a large ring structure based on mission requirements to meet various application scenarios such as space station maintenance, expansion, and antenna array deployment. The clamping plate 11 allows multiple support rods 5 to be detachably connected to each other, allowing for the construction of multiple layers of support structures. This allows for the construction of various complex spatial structures, such as multi-layer platforms, three-dimensional frames, and retractable antenna mounts, expanding the application range of spatial structures. Example

[0053] 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.

[0054] The specific implementation process is as follows: based on the principle of lever 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 support force it can provide will increase accordingly; this is because a larger diameter means a longer force arm, thereby generating a larger torque under the same force, which helps to clamp or support the assembly object more stably. Embodiment

[0055] As shown in the accompanying drawings, Figure 1 As shown, the difference from the above is that the second connecting rod 2 is hinged with a second hinge rod 4 at one end away from the rotating motor 6, the adjacent second hinge rods 4 are hinged with each other, and the second hinge rods 4 close to the first connecting rod 1 are hinged with the first connecting rod 1.

[0056] The specific implementation process is as follows: when the top second connecting rod 2 stretches outwards, the middle second connecting rod 2 is sequentially driven to stretch out by the first hinge rod 3, and as the second connecting rod 2 stretches out, the second hinge rod 4 also expands, forming a stable structure. Through the design of the second hinge rod 4, the structure is more flexible when expanding and shrinking, and the size and shape of the structure can be adjusted as needed. Embodiment

[0057] As shown in the accompanying drawings, Figure 1 As shown, the difference from the above is that the outer side of each layer of first connecting rod 1 and second connecting rod 2 is detachably and clippably connected with a vertical rod 17; the vertical rod 17 and the support rod 5 are detachably and clippably connected with an inclined rod 18.

[0058] The specific implementation process is as follows: through the design of the vertical rod 17 and the inclined rod 18, their detachable and clippable connection can be realized by quick release parts 22 and clamping parts 23, respectively, which can be installed in the corresponding positions. It has strong applicability and can form a more stable frame structure, which helps to resist various forces and torques that may be encountered during on-orbit assembly, thereby improving the stability of the device. Embodiment

[0059] As shown in the accompanying drawings, Figures 1-4 As shown, the difference from the above is that the first connecting rod 1, the second connecting rod 2, the support rod 5, the vertical rod 17 and the inclined rod 18 are all made of composite material by additive manufacturing, and the first hinge rod 3 and the second hinge rod 4 are all made of shape memory material.

[0060] The specific implementation process is as follows: the composite material has the advantages of light weight, high strength, corrosion resistance and the like, and is suitable for application in a space environment. Through the additive manufacturing technology, the components can be directly manufactured in the space, the launch cost is reduced, and the design flexibility is improved. The shape memory material has unique recovery characteristics, can recover to a preset shape at a specific temperature, can further ensure the opening and closing of the structure, and thus the stability is improved.

[0061] The technical means disclosed in the scheme of the application are not limited to the technical means disclosed in the above-mentioned embodiments, and also include technical solutions composed of any combination of the above technical features.
