Description

Technical Field

[0001] This invention relates to the field of satellite technology, specifically to a method and apparatus for mounting satellites using a vertically flip-type side panel, and more particularly to a method and apparatus for mounting satellites using a vertically flip-type side panel suitable for rapid assembly and disassembly of a single unit inside a satellite cabin. Background Technology

[0002] With the continuous release of domestic satellite constellation plans, the workload of small satellites weighing less than 1000 kg is increasing dramatically. Most small satellites have a compact structure and strict requirements for weight control. The disassembly and assembly of internal components is difficult. For example, a certain box-type satellite has a main structure composed of six structural panels. The bottom plate serves as the docking surface between the satellite and the rocket, and the top plate serves as the main functional payload. Most individual units are located on the top plate. However, due to the influence of the rocket envelope, the design distance between the top plate and the bottom plate is small. The traditional method of removing side plates still does not provide enough operating space for disassembling individual units inside the cabin. The disassembly of most individual units is high-risk and requires customized auxiliary tooling. At the same time, the line of sight is obstructed when plugging and unplugging the connectors inside the cabin, and most connectors are blind plugging and unplugging, which poses a great operational risk.

[0003] Traditional methods for removing side panels typically involve parallel docking or horizontal flip-over docking. Parallel docking requires sufficient slack in the length of the power-on cables for the side panels, resulting in a significant number of cables that cannot be secured during assembly, making satellite development risks and weight control difficult. Horizontal flip-over docking encroaches on the standing space of surrounding personnel, increases the difficulty and risk of disassembling and assembling inner-side units within the cabin, and may prevent proper insertion of cable connectors facing inwards on the top panel. Furthermore, when facing a large side panel in the height direction, the cable length during cabling is excessive, making cable weight and development costs difficult to control. Therefore, a new method is urgently needed to address these shortcomings. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a vertically flipping side plate star mounting method and apparatus.

[0005] A vertically flipping side plate star mounting method according to the present invention includes the following steps:

[0006] Step 1: Place the simulated celestial structure vertically;

[0007] Step 2: Install the tilting mechanism onto the support trolley and adjust it to the locked state. Use the support trolley to flatten the side plate interface adapter plate of the tilting mechanism.

[0008] Step 3: Install the simulated docking side plate onto the side plate interface adapter plate using the flipping mechanism, and complete the installation of the single unit inside the cabin and the installation of the cross-plate cable on the simulated docking side plate;

[0009] Step 4: Flip the simulated docking side plate to a vertical position using the support trolley;

[0010] Step 5: The transfer support trolley moves the simulated docking side plate close to the simulated celestial body structure and roughly adjusts the docking attitude of the simulated docking side plate;

[0011] Step 6: Use the support trolley to move the simulated docking side plate vertically and adjust it horizontally. Unlock the flipping mechanism from the support trolley. Use the support trolley and the flipping mechanism to move the simulated docking side plate horizontally and adjust its vertical axis. This will enable the simulated docking side plate to be precisely docked with the simulated celestial body structure. Then, complete the trial docking of the pin holes or fasteners between the simulated docking side plate and the simulated celestial body structure.

[0012] Step 7: Install the cross-plate cable between the interior of the simulated celestial body structure and the simulated docking side plate, and complete the binding and fixing at the flip joint of the simulated docking side plate to complete the single-unit installation and connector connection inside the simulated celestial body structure.

[0013] Step 8: Perform multiple simulated docking side plate flipping and trial docking using the flipping mechanism. During the flipping process, adjust the binding status of the movable cable at the flipping joint in a timely manner to prevent excessive bending, pulling, and squeezing of the cable.

[0014] Step 9: Flip the simulated docking side plate to align it with the simulated celestial structure, and install the reset pins and connecting fasteners;

[0015] Step 10: When a single unit inside the cabin needs to be temporarily removed, remove the fasteners connecting the simulated docking side plate. The simulated docking side plate can be flipped open using the flipping mechanism. After the single unit inside the cabin is removed, the simulated docking side plate can be quickly flipped and docked directly using the flipping mechanism.

[0016] Preferably, the end face of the satellite parking adapter docks with the parking interface of the simulated celestial structure, and the flatness of the docking surface is less than 0.1 mm.

[0017] Preferably, the adjustment of the unlocking and locking states between the flipping mechanism and the support trolley is determined by whether a side plate fixing block is connected between the side plate interface adapter plate of the flipping mechanism and the fixed support plate on the support trolley.

[0018] According to the present invention, a vertically flipping side plate mounting device includes a support trolley, a flipping mechanism, and a simulated star structure. The flipping mechanism is mounted on the support trolley and has a side plate interface adapter plate for fixing the simulated docking side plate. The support trolley can adjust the height and position of the simulated docking side plate, and the flipping mechanism can drive the simulated docking side plate to rotate so as to accurately dock with or separate from the simulated star structure.

[0019] Preferably, the simulated celestial structure is installed on a satellite parking rack using a satellite parking adapter.

[0020] Preferably, the flipping mechanism includes a power component, a fixed support plate, and a side plate interface adapter plate. One side of the fixed support plate is hinged to one side of the side plate interface adapter plate. The power component is fixed to the lower end of the fixed support plate and can drive the side plate interface adapter plate to rotate the simulated docking side plate around the hinge axis. The fixed support plate and the side plate interface adapter plate are locked or unlocked by connecting or removing the side plate fixing block.

[0021] Preferably, the supporting trolley includes a main supporting structure and movable wheels, support legs, an attitude adjustment mechanism, and a screw-slider moving mechanism arranged on the main supporting structure. The attitude adjustment mechanism is provided with a transfer plate fixing frame, and the fixed support plate is detachably fixed on the transfer plate fixing frame, thereby allowing the flipping mechanism to be arranged on the supporting trolley. The movable wheels can drive the flipping mechanism to move, the support legs can adjust the height of the flipping mechanism, and the attitude adjustment mechanism and the screw-slider moving mechanism can adjust the attitude of the flipping mechanism.

[0022] Preferably, the attitude adjustment mechanism includes a second adjusting handwheel, a hoist, a first fixed bracket, and a push rod; the screw-slider moving mechanism includes an adjusting bolt, a second fixed bracket, an adjusting turntable, and a moving slider; the top of the main support structure is provided with an adjusting turntable; the lower end of the moving slider is connected to the adjusting turntable; the lower end of the adapter plate fixing frame is adjustablely fixed to the upper end of the moving slider by adjusting bolts; the first fixed bracket is fixed to the upper end of the adapter plate fixing frame; the hoist is configured on the main support structure; the upper end of the push rod is rotatably engaged with the first fixed bracket; the lower end of the push rod is configured on the hoist; the hoist is provided with a second adjusting handwheel; by rotating the second adjusting handwheel, the push rod can be adjusted to move upward or downward along the axial direction of the hoist, thereby adjusting the inclination of the adapter plate fixing frame; wherein, the adapter plate fixing frame and the mounting interface adapter plate are connected by bolts; the mounting interface adapter plate is configured on the fixed support plate.

[0023] Preferably, the flipping mechanism further includes a hinge, a hinge support plate, and a reducer support plate. One side of the hinge support plate is fixed to the inner end of the fixed support plate. The side plate interface adapter plate is rotatably engaged with the hinge support plate via the hinge. The power component is fixed to the lower end of the fixed support plate via the reducer support plate.

[0024] Preferably, the power assembly includes a first adjusting handwheel, a drive shaft, a worm gear reducer, a rotating support block, and a drive flange. The first adjusting handwheel is driven by the worm gear reducer via the drive shaft. When the side plate fixing block is removed, rotating the first adjusting handwheel drives the drive flange to rotate via the drive shaft and the worm gear reducer, thereby causing the rotating support block to rotate, so that the side plate interface adapter plate drives the simulated docking side plate to rotate around the hinge axis.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. This invention enables precise docking of vertically flipped side panels for different satellite models. The vertical flipping of the side panels provides operators with optimal space for disassembling and assembling individual components within the cabin, avoiding product interference and spatial constraints. For side panels with longer heights and narrower widths, cable length can be effectively controlled. Furthermore, because the side panels are flipped for docking, cables can be secured and bound before docking, preventing disorderly bending and uncontrolled compression of cables during panel closure, effectively reducing operational risks. Repeated disassembly and assembly of the side panels does not require disconnecting the individual component connectors on the side panels, greatly reducing workload and significantly improving satellite development efficiency.

[0027] 2. This invention enables rapid vertical flipping and docking of satellite side panels, allowing for the installation of cross-panel cables within the satellite cabin in a single operation. Subsequent disassembly and assembly processes will not damage the cross-panel cables, significantly reducing the workload of plugging and unplugging individual connectors within the side panel cabin during repeated disassembly and assembly. This effectively reduces operational risks associated with processes such as live plugging and unplugging and foreign object control.

[0028] 3. By installing the flipping mechanism at different angles, this invention can adapt to side plate flipping installation under various working conditions such as horizontal axis flipping, oblique axis flipping, and vertical flipping. It provides a fast, efficient, and safe implementation method for the side plate removal process when repeatedly disassembling and assembling products such as single units, components, and test pieces inside the satellite cabin. It has a wide range of applications and provides a relatively universal side plate flipping method for satellite structural layout and process design. Attached Figure Description

[0073] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0074] Example 1:

[0075] A method for mounting stars on a vertically flip-type side panel includes the following steps:

[0076] Step 1: Place the simulated star structure 5 vertically;

[0077] Step 2: Install the flipping mechanism 2 onto the support trolley 1 and adjust it to the locked state. Use the support trolley 1 to flatten the side plate interface adapter plate 17 of the flipping mechanism 2.

[0078] Step 3: Install the simulated docking side plate 3 onto the side plate interface adapter plate 17 via the flipping mechanism 2, and complete the installation of the cabin unit 4 and the cross-plate cable 6 on the simulated docking side plate 3;

[0079] Step 4: Flip the simulated docking side plate 3 to a vertical position using the support trolley 1;

[0080] Step 5: The transfer support trolley 1 moves the simulated docking side plate 3 close to the simulated celestial structure 5 and roughly adjusts the docking attitude of the simulated docking side plate 3.

[0081] Step 6: Use the support trolley 1 to move the simulated docking side plate 3 vertically and adjust it horizontally. Unlock the flipping mechanism 2 from the support trolley 1. Use the support trolley 1 and the flipping mechanism 2 to move the simulated docking side plate 3 horizontally and adjust its vertical axis to achieve precise docking between the simulated docking side plate 3 and the simulated celestial structure 5. Complete the trial docking of the pin holes or fasteners between the simulated docking side plate 3 and the simulated celestial structure 5. The adjustment of the unlocking and locking state between the flipping mechanism 2 and the support trolley 1 is determined by whether the side plate fixing block 26 is connected between the side plate interface adapter plate 17 of the flipping mechanism 2 and the fixed support plate 16 on the support trolley 1.

[0082] Step 7: Install the cross-plate cable 6 between the interior of the simulated star structure 5 and the simulated docking side plate 3, and complete the binding and fixing at the flip joint of the simulated docking side plate 3 to complete the installation of the single unit 4 inside the cabin of the simulated star structure 5 and the connection of the connectors.

[0083] Step 8: Perform multiple simulated docking tests by flipping the side plate 3 using the flipping mechanism 2. During the flipping process, adjust the binding status of the movable cable 6 at the flipping joint in a timely manner to prevent the cable 6 from being excessively bent, pulled, or squeezed.

[0084] Step 9: Flip the simulated docking side plate 3 and mate it with the simulated celestial structure 5, and install the reset pin and connecting fasteners;

[0085] Step 10: When the single unit 4 inside the cabin needs to be temporarily removed, remove the fasteners connecting the simulated docking side plate 3. The simulated docking side plate 3 can be flipped open by the flipping mechanism 2. After the single unit 4 inside the cabin is removed, the simulated docking side plate 3 can be quickly flipped and docked directly by the flipping mechanism 2.

[0086] The present invention also provides a vertically flipping side plate satellite mounting device, including a support trolley 1, a flipping mechanism 2, and a simulated satellite structure 5. The flipping mechanism 2 is mounted on the support trolley 1 and is provided with a side plate interface adapter plate 17. The side plate interface adapter plate 17 is used to fix the simulated docking side plate 3. The support trolley 1 can adjust the height and position of the simulated docking side plate 3, and the flipping mechanism 2 can drive the simulated docking side plate 3 to rotate so as to accurately dock with or separate from the simulated satellite structure 5.

[0087] Specifically, the flipping mechanism 2 includes a power component, a fixed support plate 16, a side plate interface adapter plate 17, a hinge support plate 18, a hinge 19, and a reducer support plate 24. One side of the fixed support plate 16 is hinged to one side of the side plate interface adapter plate 17. The power component is fixed to the lower end of the fixed support plate 16 and can drive the side plate interface adapter plate 17 to rotate the simulated docking side plate 3 around the hinge axis. The fixed support plate 16 and the side plate interface adapter plate 17 are locked or unlocked by connecting or removing the side plate fixing block 26.

[0088] Specifically, the support trolley 1 includes a main support structure 38 and movable wheels 9, support legs 12, attitude adjustment mechanism 10, and screw slider moving mechanism 11 arranged on the main support structure 38. The attitude adjustment mechanism 10 is provided with a transition plate fixing frame 31. The fixed support plate 16 is detachably fixed on the transition plate fixing frame 31, thereby enabling the flipping mechanism 2 to be arranged on the support trolley 1. The movable wheels 9 can drive the flipping mechanism 2 to move, the support legs 12 can adjust the height of the flipping mechanism 2, and the attitude adjustment mechanism 10 and screw slider moving mechanism 11 can adjust the attitude of the flipping mechanism 2. The attitude adjustment mechanism 10 includes a second adjusting handwheel 27, a lifting mechanism 28, a first fixed bracket 32, and a push rod 33. The screw-slider moving mechanism 11 includes an adjusting bolt 29, a second fixed bracket 30, an adjusting turntable 34, and a moving slider 35. The top of the main support structure 38 is provided with the adjusting turntable 34. The lower end of the moving slider 35 is connected to the adjusting turntable 34. The lower end of the adapter plate fixing frame 31 is adjustablely fixed to the upper end of the moving slider 35 by the adjusting bolt 29. The first fixed bracket 32 ​​is fixed to the adapter plate fixing frame 31. At the upper end, the hoist 28 is mounted on the main support structure 38. The upper end of the push rod 33 is rotatably engaged with the first fixed bracket 32, and the lower end of the push rod 33 is mounted on the hoist 28. The hoist 28 is equipped with a second adjusting handwheel 27. By rotating the second adjusting handwheel 27, the push rod 33 can be adjusted to move upward or downward along the axial direction of the hoist 28, thereby adjusting the inclination of the adapter plate fixing frame 31. The adapter plate fixing frame 31 is connected to the mounting interface adapter plate 25 by bolts. The mounting interface adapter plate 25 is mounted on the fixed support plate 16.

[0089] One side of the hinge support plate 18 is fixed to the inner end of the fixed support plate 16. The side plate interface adapter plate 17 is rotatably engaged with the hinge support plate 18 via the hinge 19. The power assembly is fixed to the lower end of the fixed support plate 16 via the reducer support plate 24. The power assembly includes a first adjusting handwheel 13, a drive shaft 14, a worm gear reducer 15, a rotating support block 22, and a drive flange 23. The first adjusting handwheel 13 is driven by the worm gear reducer 15 via the drive shaft 14. When the side plate fixing block 26 is removed, rotating the first adjusting handwheel 13 drives the drive flange 23 to rotate via the drive shaft 14 and the worm gear reducer 15, thereby driving the rotating support block 22 to rotate, so that the side plate interface adapter plate 17 drives the simulated docking side plate 3 to rotate around the axis of the hinge 19.

[0090] Example 2:

[0091] This embodiment is a preferred example of Embodiment 1. This embodiment provides a vertical flip-type side panel satellite mounting method adapted for rapid assembly and disassembly of a single unit inside the satellite cabin. The device using the vertical flip-type side panel satellite mounting method includes a support trolley 1, a flipping mechanism 2, a simulated docking side panel 3, a simulated satellite structure 5, a satellite parking and transfer fixture 7, and a satellite parking rack 8. The method includes the following steps:

[0092] Step 1: Place the simulated celestial body structure 5 vertically on the satellite parking rack 8. The simulated celestial body structure 5 and the satellite parking rack 8 are connected by a satellite parking adapter 7. The satellite parking adapter 7 is a ring structure. The end face of the satellite parking adapter 7 is connected to the parking interface of the simulated celestial body structure 5, and the flatness of the docking surface is required to be better than 0.1mm.

[0093] Step 2: Install the flipping mechanism 2 onto the support trolley 1 and adjust it to the locked state. Use the support trolley 1 to flatten the side plate interface adapter plate 17 of the flipping mechanism 2.

[0094] Step 3: Install the simulated docking side plate 3 onto the side plate interface adapter plate 17, and complete the installation of the cabin unit 4 and the cross-plate cable 6 on the simulated docking side plate 3;

[0095] Step 4: Flip the simulated docking side plate 3 to a vertical position using the support trolley 1;

[0096] Step 5: The transfer support trolley 1 moves the simulated docking side plate 3 close to the simulated celestial structure 5 and roughly adjusts the docking attitude of the simulated docking side plate 3.

[0097] Step 6: Use the four sets of support legs 12 at the bottom of the support trolley 1 to move the simulated docking side plate 3 in the vertical direction and adjust it horizontally. Unlock the flipping mechanism 2 from the support trolley 1. Use the screw slider mechanism 11 and the flipping mechanism 2 on the support trolley 1 to move the simulated docking side plate 3 in the horizontal direction and adjust its deflection in the vertical axis. Fine-tune the position and attitude of the simulated docking side plate 3 through the above six degrees of freedom to achieve precise docking between the simulated docking side plate 3 and the simulated celestial structure 5. Complete the test docking of the pin holes or fasteners between the simulated docking side plate 3 and the simulated celestial structure 5.

[0098] Step 7: Install the cross-plate cable 6 between the interior of the simulated star structure 5 and the simulated docking side plate 3, and complete the binding and fixing at the flip joint of the simulated docking side plate 3 to complete the installation of the single unit 4 inside the cabin of the simulated star structure 5 and the connection of the connectors.

[0099] Step 8: Perform multiple simulated docking tests by flipping the side plate 3 using the flipping mechanism 2. During the flipping process, adjust the binding status of the movable cable 6 at the flipping joint in a timely manner to prevent the cable 6 from being excessively bent, pulled, or squeezed.

[0100] Step 9: Flip the simulated docking side plate 3 and mate it with the simulated celestial structure 5, and install the reset pin and connecting fasteners;

[0101] Step 10: When the single unit 4 inside the cabin needs to be temporarily removed, remove the fasteners connecting the simulated docking side plate 3. The simulated docking side plate 3 can be flipped open by the flipping mechanism 2. After the single unit 4 inside the cabin is removed, the simulated docking side plate 3 can be quickly flipped and docked directly by the flipping mechanism 2.

[0102] It should be noted that the adjustment of the unlocking and locking states between the flipping mechanism 2 and the support trolley 1 is determined by whether the side plate fixing block 26 is connected between the side plate interface adapter plate 17 of the flipping mechanism 2 and the fixed support plate 16 on the support trolley 1. When the side plate interface adapter plate 17 and the fixed support plate 16 are connected, it is in the locked state; when the side plate fixing block 26 is not connected, it is in the unlocked state.

[0103] The supporting trolley 1 serves as a parking device for the tilting mechanism 2 and the simulated docking side plate 3, and is screwed to the tilting mechanism 2, as shown below. Figure 3 As shown, the flipping mechanism 2 includes a first adjusting handwheel 13, a drive shaft 14, a worm gear reducer 15, a fixed support plate 16, a side plate interface adapter plate 17, a hinge support plate 18, a hinge 19, a conformal block 21, a rotating support block 22, a drive flange 23, a reducer support plate 24, a mounting interface adapter plate 25, and a side plate fixing block 26. Figure 5As shown, the support trolley 1 includes moving wheels 9, support legs 12, attitude adjustment mechanism 10, screw slider moving mechanism 11, and main support structure 38. The attitude adjustment mechanism 10 includes a second adjusting handwheel 27, a lifting machine 28, a transfer plate fixing frame 31, a first fixing bracket 32, and a push rod 33. The screw slider moving mechanism 11 includes an adjusting bolt 29, a second fixing bracket 30, an adjusting turntable 34, and a moving slider 35. The screw slider moving mechanism is mainly used by the support trolley 1 for parking, transporting, and attitude adjustment of the flipping mechanism 2 and the simulated docking side plate 3.

[0104] Specifically, the bottom of the main support structure 38 is equipped with four casters 9 and multiple support legs 12. The overall height of the adapter plate fixing frame 31 can be adjusted by the support legs 12. When movement is required, the support legs 12 are retracted, and the support trolley 1 can be moved by the rolling of the casters 9. The main support structure 38 is also equipped with a handrail 37. The handrail 37 is rotatably engaged with the main support structure 38 by a rotating component 36. Pulling the handrail 37 can drag the support trolley 1 to move. The orientation of the front end of the handrail 37 can be adjusted by the rotating component 36 for easy gripping.

[0105] like Figure 5As shown, an adjusting turntable 34 is provided on the top of the main support structure 38. The lower end of the movable slider 35 is connected to the adjusting turntable 34. The lower end of the adapter plate fixing frame 31 is adjustablely fixed to the upper end of the movable slider 35 by adjusting bolts 29. The first fixing bracket 32 ​​is fixed to the upper end of the adapter plate fixing frame 31. The hoist 28 is configured on the main support structure 38. The upper end of the push rod 33 is rotatably engaged with the first fixing bracket 32, and the lower end of the push rod 33 is configured on the hoist 28. The hoist 28 is provided with a second adjusting handwheel 27. By rotating the second adjusting handwheel 27, the push rod 33 can be adjusted to move up or down along the axial direction of the hoist 28, thereby adjusting the inclination of the adapter plate fixing frame 31. The adapter plate fixing frame 31 is bolted to the mounting interface adapter plate 25, which is configured on the fixed support plate 16. The outer end of the fixed support plate 16 is detachably fixed to the side plate interface adapter plate 17 by a side plate fixing block 26. The side plate interface adapter plate 17 is provided with a connection hole 20, which can be connected to the simulated docking side plate 3 through the connection hole 20 with matching bolts. One side of the hinge support plate 18 is fixed to the inner end of the fixed support plate 16. The side plate interface adapter plate 17 is rotatably engaged with the hinge support plate 18 through the hinge 19. The worm gear reducer 15 is fixed to the lower end of the fixed support plate 16 through the reducer support plate 24. When the side plate fixing block 26 is removed, rotating the first adjusting handwheel 13 can drive the drive flange 23 to rotate through the transmission shaft 14 and the worm gear reducer 15, thereby driving the rotating support block 22 to rotate, which in turn causes the side plate interface adapter plate 17 to drive the simulated docking side plate 3 to rotate around the axis of the hinge 19. The conformal block 21 is provided on one side of the rotating support block 22 to increase the support strength of the rotating support block 22.

[0106] like Figure 3 , Figure 4 As shown, the flipping mechanism 2 is the core component of the present invention. It is connected to the support trolley 1 as a whole and has the functions of multi-degree-of-freedom adjustment, realizing the vertical rapid flipping of the simulated docking side plate 3, attitude locking, and stiffness maintenance. Through different installation and fixing methods, it can meet the requirements of flipping and docking of the simulated docking side plate 3 around the vertical axis, horizontal axis, and oblique axis.

[0107] The mounting interface adapter plate 25 is used to connect with the adapter plate fixing frame 31 on the support trolley 1. It is integrally formed from a 15mm thick aluminum alloy plate, with 4 sets of M10 threaded through holes as adapter interfaces. The 4 sets of interfaces are connected to the support trolley 1, and the 4 sets of interfaces are connected to the fixed support plate 16.

[0108] The fixed support plate 16 serves as the main support and provides the hinge support plate 18, reducer support plate 24, conformal block 21, and conformal block 21 connection interface. It is integrally formed from a 20mm thick aluminum alloy plate. Loosening the connection between the side plate fixing block 26 of the flipping mechanism 2 and the side plate interface adapter plate 17 allows the side plate interface adapter plate 17 to rotate around the hinge 19 axis.

[0109] The hinge support plate 18 is used to provide an installation interface for the 7-piece hinge 19. It is installed on the side of the fixed support plate 16, raising the distance between the hinge 19 and the fixed support plate 16 to ensure that there is enough space when the side plate interface adapter plate 17 is flipped.

[0110] The hinge 19 provides an installation interface for the side panel interface adapter plate 17 and serves as the main flip axis. The hinge 19 is coaxially mounted with the flip axis and together supports the weight of the side panel interface adapter plate 17 and the simulated docking side panel 3 after installation.

[0111] The side panel interface adapter plate 17 is used to provide a simulated docking side panel 3 installation interface. It is made of 25mm aluminum alloy plate as a whole. According to the stress simulation analysis, the non-load-bearing area in the middle is hollowed out for weight reduction, and 4 sets of weight reduction grooves are processed on the back.

[0112] The rotating support block 22 is used to connect the drive flange 23 and the side plate interface adapter plate 17, converting the pitch circle distribution interface connection into a straight distribution interface connection.

[0113] The reducer support plate 24 is connected to the lower end of the fixed support plate 16 to provide an installation interface for the worm gear reducer 15, and has an arc-shaped notch for temporary fixation when the simulated docking side plate 3 is flipped.

[0114] The conformal block 21 is designed with a triangular structure to connect and fix the half-box reducer support plate 24, ensuring the connection strength of the reducer support plate 24.

[0115] The worm gear reducer 15 serves as the main drive mechanism of the tilting mechanism 2, with a reduction ratio of 1:10. The power input end is connected to the drive handwheel 13. The output shaft of the worm gear reducer 15 is coaxially mounted with the rotating shaft of the 7-assembly hinge 19. The output end is connected to the lower end of the side plate interface adapter plate 17. When the first adjusting handwheel 13 is driven to rotate, it drives the side plate interface adapter plate 17 and the simulated docking side plate 3 to rotate along the rotating shaft of the hinge 19.

[0116] The drive flange 23 is used to connect the output shaft of the worm gear reducer 15 to the rotating support block 22, converting the axial key connection into a planar pitch circle distributed interface connection.

[0117] The drive shaft 14 and the first adjusting handwheel 13 are used to provide the power for the vertical flipping of the simulated docking side plate 3. The simulated docking side plate 3 is slowly flipped and docked by manually rotating the handwheel clockwise or counterclockwise.

[0118] The side plate fixing block 26 is used to lock and support the simulated docking side plate 3 when it is flipped to be parallel with the fixed support plate 16. In this state, the flipping mechanism 2 is in a fully free-degree-of-freedom locked state with good stability and can be used for the transfer and flipping of the simulated docking side plate 3.

[0119] The simulated docking side plate 3 is the main object to be removed before and after the disassembly and assembly of the single unit 4 inside the cabin. After its removal, the normal disassembly of all products inside the satellite cabin can be met.

[0120] The simulated satellite structure 5 is the main target for dismantling the internal single unit 4. Its configuration is a typical single-compartment box structure, which is a typical layout structure of small satellite products. Its characteristics are that the structure layout is compact, the internal single unit 4 connectors face inward, and the internal operating space is limited. Under the condition that the simulated docking side plate 3 has not been removed, the internal single unit 4 of the satellite cannot be dismantled normally.

[0121] The satellite parking adapter 7 is mainly used as an interface adapter. The upper surface is the product docking surface, which provides a high-precision product docking interface and flatness. The lower end docks with the factory's general-purpose satellite parking rack 8 to achieve effective docking between the product and the satellite parking rack 8.

[0122] Satellite parking rack 8 serves as the main parking device for simulating celestial bodies, meeting the needs for satellite parking and transportation.

[0123] This invention provides a relatively universal side-panel mounting method for the assembly and disassembly of the internal unit 4 of a compact small satellite. The internal unit 4 has good operating space during assembly and disassembly, avoiding multiple plugging and unplugging of the internal unit connectors on the side panel and excessive redundancy in cable length. This effectively reduces the risk of satellite development and significantly improves satellite development efficiency and maintainability.
