Description

Technical Field

[0001] This invention relates to the field of spacecraft technology, and more specifically, to a multi-functional integrated flipping device for flat-panel satellites. Background Technology

[0002] Flat-panel satellites require assembly and testing in multiple states, including horizontal and vertical, during development. Traditional satellite flipping solutions use side-plate carriages or two-axis turntables. When using these fixtures, one side of the flat-panel satellite is connected to the fixture. On this connected side, interference from the fixture often prevents onboard operations. After one side of the satellite is completed, the fixture must be replaced and the satellite flipped to work on the other side. This flipping and attitude adjustment process is complex, requiring multiple fixture changes, resulting in low efficiency. Furthermore, there are risks of snagging and collisions during satellite flipping and fixture changes. Current equipment solutions also cannot address the need for simultaneous operation on both sides of the flat-panel satellite. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a multi-functional integrated flipping device for flat-panel satellites.

[0004] A multi-functional integrated flipping device for flat-panel satellites provided by the present invention includes:

[0005] The base module features height adjustment and mobility.

[0006] A flipping module is configured on the base module and is capable of flipping between a horizontal and a vertical state;

[0007] A rotation module, configured on the flipping module, is used to assemble the flat-panel satellite and enables the flat-panel satellite to rotate around its axis, thereby adjusting the attitude of the flat-panel satellite.

[0008] Preferably, the base module includes a support base and an L-shaped guide rail. The L-shaped guide rail is arranged on the support base, and the flipping module can slide on the L-shaped guide rail to achieve flipping between the horizontal and vertical states.

[0009] Preferably, the support base is provided with at least 3 omnidirectional casters and at least 3 locking struts, the locking struts being able to fix the position of the support base and to coarsely and finely adjust the height of the support base.

[0010] Preferably, the flipping module includes a rocker mechanism, sliders, and a flipping frame. The two sliders are disposed at both ends of one side of the flipping frame. The middle part of the rocker mechanism is rotatably engaged with the support base, and the front end of the rocker mechanism is rotatably engaged with one side of the flipping frame. Driving the rear end of the rocker mechanism allows the rocker mechanism to rotate around the axis that is rotatably engaged with the support base, thereby causing the two sliders to slide on the L-shaped guide rail, thus realizing the flipping between the horizontal and vertical states.

[0011] Preferably, the flipping module further includes a lead screw, a first handwheel, and a reducer. When the first handwheel is rotated, the reducer can drive the lead screw to move in the axial direction, thereby driving the rear end of the rocker mechanism to move. The lower end of the lead screw is rotatably engaged with the rear end of the rocker mechanism.

[0012] Preferably, the rotating module includes a satellite bracket and a rotating device. The flipping module has a flipping frame. One satellite bracket is configured on one side of the flipping frame via the rotating device, and another satellite bracket is configured on the other side of the flipping frame via a pin. The two sides of the flat-panel satellite can be respectively mounted onto the two satellite brackets.

[0013] Preferably, the rotating device is driven to rotate by a second handwheel connected to a rotating worm gear mechanism, thereby achieving a 360° rotation of the flat satellite around its axis.

[0014] Preferably, the support base is equipped with a protective frame, the size of which is larger than the outer envelope of the flat satellite in its flipped state.

[0015] Preferably, the L-shaped guide rail is positioned on the support base by two guide rail brackets.

[0016] Preferably, the locking strut achieves the fine-tuning function through a universal ball joint located at its bottom.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention, by setting a flipping module on the base module and configuring a rotation module on the flipping module for mounting a flat-panel satellite, enables the use of only a single set of tooling equipment to achieve all different attitude conditions during the development stage of the flat-panel satellite. This achieves efficient assembly, integration, and testing of the flat-panel satellite, eliminating the need to change different tooling to achieve different attitudes during satellite development, saving development time and tooling costs. Furthermore, it allows for simultaneous assembly and testing of both sides of the flat-panel satellite. This invention is applicable to the flipping and attitude adjustment of large flat-panel satellites, solving the problems of needing to change tooling when adjusting different attitudes during the assembly of large flat-panel satellites and the need for simultaneous operation on both sides of the flat-panel satellite. It has good versatility and strong practicality. Attached Figure Description

[0049] 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.

[0050] This invention provides a multi-functional integrated flipping device for flat-panel satellites, such as... Figure 1 As shown, the system includes a base module, a flip module, and a rotation module. The base module provides overall support and includes a support base 11 and an L-shaped guide rail 4. The L-shaped guide rail 4 is positioned on the support base 11 via two guide rail brackets 8. Three omnidirectional casters 6 are mounted on the bottom of the support base 11, and three locking struts 7 are also mounted on it. The height of the locking struts 7 is adjusted via internal screws 18, and each locking strut 7 has a support nut 16 for support. A ball joint 17 is also mounted on the base of the locking strut 7. In actual use, the equipment is moved and transported as a whole using the three omnidirectional casters 6. Handrails 13 are provided on the L-shaped guide rail 4 for easy movement. After the flat satellite 1 is in place, the support nut 16 of the locking strut 7 is rotated to lock its position. Simultaneously, the overall equipment is leveled by adjusting the height of the three locking struts 7, including coarse and fine adjustments. When the position of the flat satellite 1 needs to be fine-tuned, unscrew the universal ball joint 17 at the bottom of the locking strut 7. The position of the flat satellite 1 can be fine-tuned through the three universal ball joints 17.

[0051] The flipping module includes a flipping frame 3, sliders 5, a rocker mechanism 10, a lead screw 12, a first handwheel 14, and a reducer 19. Two sliders 5 are mounted on the flipping frame 3, and two vertically arranged slide rails are provided on the L-shaped guide rail 4. The two sliders 5 can slide within the two slide rails on the L-shaped guide rail 4 respectively. The flipping frame 3 is driven by the rocker mechanism 10, which is driven by the lead screw 12. By rotating the first handwheel 14, the reducer 19 can be driven to move the lead screw 12. The lead screw 12 drives the rocker mechanism 10 to move. The rocker mechanism 10 drives the flipping frame 3 to flip by moving the sliders 5 on the L-shaped guide rail 4, thereby realizing the horizontal to vertical flipping of the flat satellite 1.

[0052] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, two sliders 5 are set at both ends of one side of the flip frame 3. The middle part of the rocker mechanism 10 is rotatably engaged with the support base 11, the front end of the rocker mechanism 10 is rotatably engaged with one side of the flip frame 3, the lower end of the lead screw 12 is rotatably engaged with the rear end of the rocker mechanism 10, and the upper end of the lead screw 12 is driven and connected to the reducer 19. When the reducer 19 is running, it can drive the lead screw 12 to move upward, thereby driving the rear end of the rocker mechanism 10 to rotate around the axis that is rotatably engaged with the support base 11, so that the two sliders 5 slide on the L-shaped guide rail 4, thereby realizing the switching between the horizontal and vertical states.

[0053] It should be noted that the support base 11 is equipped with a protective frame 15. The size of the protective frame 15 is larger than the outer envelope of the flat satellite 1 in the flipped state, which can protect the flat satellite 1 during the flipping process.

[0054] like Figure 5 As shown, the rotating module includes a satellite support 2 and a rotating device 9. The satellite support 2 is divided into two parts. One satellite support 2 is configured on one side of the flip frame 3 through the rotating device 9, and the other satellite support 2 is configured on the other side of the flip frame 3 through the pin 21. The two sides of the flat satellite 1 can be assembled onto the two satellite supports 2 respectively. In practical applications, the rotating device 9 is driven to rotate through the second handwheel 20 connected by the rotating worm gear mechanism, so as to realize the 360° rotation of the flat satellite 1 around the axis.

[0055] The principle behind the flipping of flat-panel satellite 1 from a horizontal to a vertical position is as follows:

[0056] like Figure 6As shown, the flat satellite 1, which is in a horizontal state, is arranged on the flipping frame 3. Rotating the first handwheel 14 drives the reducer 19 to drive the lead screw 12 to move upward. The lower end of the lead screw 12 drives the outer end of the rocker mechanism 10 to move upward. The rocker mechanism 10 rotates around the central rotation axis, thereby driving the inner end of the rocker mechanism 10 to drive the flipping frame 3 to slide and flip on the L-shaped guide rail 4 through the slider 5, and finally realizes the flipping of the flat satellite 1 to a vertical state.

[0057] The principle behind the rotation of the horizontally positioned flat-panel satellite 1 around its axis is as follows:

[0058] like Figure 7 As shown, the flat satellite 1, which is in a horizontal position, is arranged on the flip frame 3. The second handwheel 20 can drive the rotating device 9 to rotate. The rotating device 9 is connected to a satellite support 2, which in turn drives the satellite support 2 to rotate, so that the flat satellite 1 assembled on the satellite support 2 rotates, realizing the 360° rotation of the flat satellite 1 around the axis.
