Description

Technical Field

[0001] This utility model relates to the field of satellite technology, specifically to a flat-panel satellite multi-functional assembly device. Background Technology

[0002] With the rapid development of satellite internet technology, to achieve the goal of rapid network deployment, it is necessary to launch a large number of satellites in a short period of time to fully utilize rocket carrying capacity and complete the launch mission of multiple satellites at once. Driven by this demand, satellite design concepts and physical forms have undergone revolutionary changes. Traditional three-dimensional satellite structures have been compressed into two-dimensional flat-panel open configurations. These large flat-panel satellites have significant structural characteristics—their length and width are both no less than 2 meters, and their height is no more than 0.5 meters. Dozens of satellites can be launched in a single launch by stacking them layer by layer. Currently, the ground equipment used in the satellite assembly field is developed and designed based on the assembly requirements of traditional three-dimensional satellite structures, and its structure and function are adapted to the morphological characteristics of traditional satellites. At the same time, there is currently no technologically mature ground equipment on the market specifically designed for the assembly process of large flat-panel satellites, and related assembly operations still rely on temporary adjustments and adaptations to traditional equipment.

[0003] Existing satellite assembly ground equipment, designed for traditional three-dimensional satellite structures, cannot meet the assembly and testing requirements of large flat-panel satellites in terms of size adaptability and functional coverage. On one hand, large flat-panel satellites require simultaneous horizontal and vertical positioning, satellite rotation, precise positioning, attitude maintenance, and short-distance transport within the factory during operation. Existing traditional equipment can only perform one or a few of these tasks, requiring multiple machines to coordinate, which not only increases the complexity and difficulty of the workflow but also easily reduces assembly accuracy due to coordination errors between machines. On the other hand, traditional equipment lacks a dedicated adaptive structure for flat-panel satellites. When temporarily adjusted for flat-panel satellite assembly, it is difficult to guarantee the long-term stability of the satellite's attitude, posing assembly safety hazards and resulting in low overall operational efficiency, failing to meet the urgent requirements of rapid satellite internet network deployment for satellite production and assembly.

[0004] Therefore, a new technological solution is needed. Utility Model Content

[0057] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0058] like Figure 1-3As shown, this utility model provides a multi-functional assembly device for a flat-panel satellite 6, including a moving structure 1, two lifting structures 2, a rotating structure 3, and a satellite parking structure 4. The moving structure 1 is capable of omnidirectional movement; the two lifting structures 2 are positioned opposite each other on both sides of the moving structure 1, each lifting structure 2 including a guide rail 21, a drive unit 22, and a parking unit 23. The guide rail 21 is fixed to the top of the moving structure 1, and the drive unit 22 drives the parking unit 23 to move along the guide rail 21; the rotating structure 3 includes an active unit 31 and a driven unit 32, which are correspondingly mounted on the two parking units 23; the satellite parking structure 4 is located between the active unit 31 and the driven unit 32, and is connected to both the active unit 31 and the driven unit 32, for mounting the flat-panel satellite 6 and driving the flat-panel satellite 6 to rotate under the drive of the active unit 31.

[0059] Among them, the movable structure 1 is used to drive the entire device to move forward, backward, left, and right, so as to realize short-distance transfer of the device or angle adjustment of the flat-panel satellite 6.

[0060] The lifting structure 2 is used to drive the rotating structure 3 and the satellite parking structure 4 to move up and down, so as to adjust the height of the flat-panel satellite 6.

[0061] The rotating structure 3 is used to drive the satellite parking structure 4 to rotate, thereby rotating the flat-panel satellite 6 and locking the flat-panel satellite 6 at a preset angle.

[0062] Among them, satellite parking structure 4 is used to install flat-panel satellite 6.

[0063] Furthermore, the movable structure 1 includes a support portion 11 and a movable portion 12. The support portion 11 is used to mount the support guide rail 21 at least; the movable portion 12 is disposed at the bottom end of the support portion 11 and is used to drive the support portion 11 to perform at least one of forward, backward, turning, rotating in place, and lateral translation.

[0064] Preferably, the moving part 12 includes a Mecanum wheel or a steering wheel.

[0065] Among them, the support unit 11 serves as the support platform for the flat-panel satellite 6 multi-functional assembly equipment. In addition to providing the main structure of the entire equipment, it is also equipped with power supply, drive motor, control system, etc., to realize the various functions of the entire equipment.

[0066] The power supply provides electricity to the entire device, the drive motor drives the Mecanum wheel or steering wheel to rotate, and the control system controls the operation of the drive motor to achieve functions such as forward, backward, turning, rotating in place, and lateral translation.

[0067] As the weight of the flat-panel satellite 6 increases, the aforementioned functions can be achieved using a steering wheel.

[0068] Furthermore, there are multiple guide rails 21, which are fixed to the top of the movable structure 1, and the top of the guide rails 21 are connected and fixed by connecting blocks.

[0069] For example, the guide rail 21 includes two opposing guide rails 21 and a guide rail 21 located on one side of the two opposing guide rails 21. The multiple guide rails 21 are used to improve the stability of the slider 222 in the drive unit 22.

[0070] Preferably, the guide rail 21 includes a left guide rail 21, a right guide rail 21, and a front guide rail 21 located on one side of the left and right guide rails 21.

[0071] The connecting block is used to ensure the stability of the top ends of multiple guide rails 21.

[0072] In some embodiments, a support rod is provided on one side of the guide rail 21, with one end of the support rod connected to the movable structure 1 and the other end obliquely connected to one side of the guide rail 21 to increase the stability of the guide rail 21.

[0073] The drive unit 22 includes a worm gear reducer, a worm 221, and a slider 222. The worm gear reducer is mounted on or inside the movable structure 1. One end of the worm 221 is connected to the output end of the worm gear reducer, and the other end is located between the two guide rails 21 and fixed to the connecting block. The slider 222 is fitted onto the worm 221 through a threaded hole, and is slidably connected to the two guide rails 21 and fixedly connected to the parking part 23.

[0074] The worm gear reducer is used to drive the worm 221 to rotate. When the worm 221 rotates, the slider 222 cannot rotate because it is restricted by the guide rail 21, and thus moves up and down along the worm 221.

[0075] For example, worm 221 is a threaded rod.

[0076] The parking section 23 has an installation interface on its upper part, which is connected to the rotating structure 3 by bolts or threads.

[0077] During the assembly and testing of Satellite 6, if it is necessary to adjust the altitude of Satellite 6, the operating altitude can be set through the external control panel. Then, after receiving the instruction, the worm gear reducer will start working to drive the worm 221 to rotate, so that the worm 221 can drive the parking part 23 to rise and fall through the slider 222.

[0078] The sliding between the guide rail 21 and the slider 222 can also reduce the frictional resistance during the lifting and lowering of the parking part 23.

[0079] Since the slider 222 is fixed to the worm 221 when it cannot rotate, after the lifting structure 2 drives the parking part 23 to the specified height, the weight of the combination of satellite 6, satellite parking structure 4, rotating structure 3 and parking part 23 is insufficient to make the slider 222 move relative to the worm 221, thus realizing the self-locking function in the height direction.

[0080] In some embodiments, the rotating structure 3 may employ a crank-slider 222 to accommodate a heavier flat-panel satellite 6.

[0081] Furthermore, the active unit 31 includes a rotary reducer 311, a drive shaft 312, and a bearing 313. The rotary reducer 311 is mounted on a corresponding parking section 23, with its output shaft facing the opposite parking section 23. The rotary reducer 311 is used to achieve at least forward rotation, reverse rotation, angle adjustment, and self-locking functions. The drive shaft 312 is connected to the output shaft of the rotary reducer 311 and is fixedly connected to the side of the satellite parking structure 4. The bearing 313 is sleeved on the drive shaft 312 and fixed to the corresponding parking section 23 by a bracket, serving to support the drive shaft 312.

[0082] Among them, the rotary reducer 311 can rotate the satellite 6 to any angle according to the working requirements and achieve long-term stable attitude maintenance.

[0083] Among them, the drive shaft 312 is used to actively drive the satellite parking structure 4 to rotate under the action of the rotary reducer 311 and follow the rotary reducer 311 to self-lock.

[0084] Among them, the bearing 313 is used to cooperate with the bracket to support the drive shaft 312 and reduce the pressure on the drive shaft 312.

[0085] The driven part 32 includes a driven shaft 321 and a driven seat 322. One end of the driven shaft 321 is connected to the other side of the satellite parking structure 4 and is coaxially arranged with the drive shaft 312; the driven seat 322 is fixed to the corresponding parking part 23 and is rotatably connected to the other end of the driven shaft 321.

[0086] The driven shaft 321 is used to fix the other end of the satellite parking structure 4, and after the rotary reducer 311 is working, it works with the active part 31 to drive the satellite parking structure 4 to rotate.

[0087] The driven shaft 321 can be connected to the driven seat 322 via a bearing.

[0088] For example, bearing 313 is embedded in driven seat 322, and driven shaft 321 is embedded in the inner ring of bearing 313.

[0089] Specifically, in actual operation, after the rotation angle is set through the external control panel, the rotary reducer 311 can start working according to the received instructions, driving the drive shaft 312 to rotate. Since the drive shaft 312, driven shaft 321 and satellite parking structure 4 are connected and fixed to form a whole, the rotation of the whole is realized during the rotation of the drive shaft 312.

[0090] In some of these embodiments, the flat-panel satellite 6 multi-functional assembly equipment also includes a safety redundancy device 5, which is used to lock the satellite parking structure 4 at a preset angle.

[0091] The safety redundancy device 5 includes a positioning plate 51 and a positioning pin 52. The positioning plate 51 is fitted onto the driven shaft 321 and has a positioning hole thereon; the positioning pin 52 passes through the driven seat 322 and is set corresponding to the positioning hole.

[0092] The positioning pin 52 and the corresponding positioning hole are at the same height. The positioning pin 52 passes through the driven seat 322 and then through the corresponding positioning hole. The positioning plate 51 can limit the driven shaft 321, thereby locking the satellite parking structure 4.

[0093] After satellite 6 is rotated to the preset angle, the positioning pin 52 is inserted into the corresponding hole. If the rotary reducer 311 malfunctions and rotates on its own, the combination of satellite 6 and satellite 6 parking frame will still not be able to rotate due to the limiting effect between the positioning pin 52 and the positioning plate 51. This can effectively ensure the safety of satellite 6 during assembly and testing.

[0094] Furthermore, the satellite parking structure 4 includes a frame section 41, multiple mounting bases 42, and a hoisting section 43. The frame section 41 is fixed between the active part 31 and the driven part 32; the multiple mounting bases 42 are correspondingly disposed on the frame section 41 for mounting and limiting the flat-panel satellite 6; the hoisting section 43 is disposed on the side of the frame section 41 for hoisting the satellite parking structure 4.

[0095] The frame section 41 can be a U-shaped structure composed of metal tubes.

[0096] The length and width of the frame section 41 are slightly larger than those of the flat-panel satellite 6. The position and connection interface of the mounting base 42 match the specific mounting interface of the flat-panel satellite 6.

[0097] The satellite 6 parking frame can be connected to the flat-panel satellite 6 via a threaded connection.

[0098] The hoisting unit 43 can be located at the four corners of the frame unit 41 to hoist the combination of satellite 6 and satellite 6 parking frame off the flat-panel satellite 6 multi-functional assembly equipment.

[0099] Furthermore, the flat-panel satellite 6 multi-functional assembly equipment also includes a control panel, which is electrically connected to the lifting structure 2 and the rotating structure 3 respectively, to control the lifting structure 2 and the rotating structure 3.

[0100] The control panel is electrically connected to the rotary reducer 311 and the turbine reducer to adjust the operating altitude and rotation angle of satellite 6.

[0101] This utility model boasts comprehensive functions and a high degree of integration. A single device can perform multiple functions during the assembly and testing of a large flat-panel satellite, including horizontal and vertical placement, satellite rotation, precise positioning, attitude maintenance, and short-distance transport within the factory. Furthermore, it adopts a standardized, interchangeable, and modular design, reducing production and maintenance costs. Simultaneously, it allows for independent movement in different directions without interference and features a self-locking function at any position.

[0102] In this specification, the same or similar parts between the various embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, for the product embodiments described later, since they correspond to the methods, the descriptions are relatively simple, and the relevant parts can be referred to the descriptions in the system embodiments.

[0103] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
