Abstract
Description
Technical Field
[0001] This invention relates to the field of spacecraft docking technology, specifically to a spacecraft docking and separation mechanism and docking components. Background Technology
[0002] Space rendezvous and docking comprises two steps: rendezvous and docking. Rendezvous refers to the meeting of spacecraft at a specific location in space, while docking refers to the structural and functional integration of the spacecraft into a rigid whole. Rapid, autonomous rendezvous and docking is an inevitable trend in the future development of rendezvous and docking, especially as major spacefaring nations gradually increase investment in space engineering and conduct in-depth research on space resource utilization technologies and strategies. Modular spacecraft, on-orbit assembly, maintenance, and lifespan extension of spacecraft, as well as concepts such as cellular spacecraft, have become key research areas. A highly integrated docking mechanism with energy and signal transmission capabilities and rapid docking, separation, and locking functions is a prerequisite for the development of these technologies and a crucial foundation for the modularization and on-orbit construction of spacecraft.
[0003] Currently, in-orbit docking mechanisms are mainly large docking structures between two spacecraft or between large payload equipment and the space station, enabling the transfer of mechanical, electrical, thermal, and fluid resources. However, with the development of manufacturing, communication, and software technologies, and the continuous improvement of human capabilities in space exploration and application, a large number of spacecraft designed for various space missions have been developed. While their technology and performance levels are constantly improving, their structures and compositions are also becoming increasingly complex. To adapt to the docking requirements between different specifications and types of space payloads, docking mechanisms need to have strong universal interfaces and adaptability, and improve integration to meet various types of in-orbit docking needs.
[0004] Traditional space rendezvous and docking mechanisms rely on inertia to perform rigid collision-type hard docking at the end of the docking process. The resulting large impact force affects the safety of precision instruments and equipment, is not conducive to repeated docking, and damages the lifespan of the docking mechanism.
[0005] In addition, traditional docking mechanisms are relatively complex. For example, the space docking mechanism positioning lock that can repeatedly lock / unlock requires a motor arranged inside to drive the ball screw, slider, and gear mechanism to move in both forward and reverse directions to achieve the locking and unlocking functions. The structure and operation are both relatively complex.
[0006] Patent CN201810709931.7 discloses a space docking and locking mechanism that employs an asymmetrical V-shaped guide structure combined with a single claw structure to replace the gripper claw. The integrated V-shaped guide structure with damping buffer support provides efficient buffering and continues to buffer during subsequent locking, effectively reducing vibration. However, the linear contact connection method has low fault tolerance and poor load-bearing stability.
[0007] Therefore, a new technical solution is needed to solve the above problems. Summary of the Invention
[0008] To address the problems arising from existing technologies, this invention provides a homogeneous telecom integration docking mechanism that features short docking time, large tolerance, high precision, high integration, miniaturization, and long reuse life.
[0009] The present invention also provides a technical solution that includes the above two docking mechanisms that can dock with each other as docking components.
[0010] To achieve the above objectives, the present invention provides a homogeneous integrated telecommunications docking mechanism, which can adopt the following technical solution:
[0011] An isomorphic mechatronics docking mechanism includes a housing, a docking plate covering the housing, a locking plate located inside the housing, and a drive device for rotating the locking plate; the docking plate is provided with an outwardly protruding mechatronics cone rod and a docking port penetrating the docking plate; the mechatronics cone rod and the docking port are symmetrically arranged about the central axis of the locking plate;
[0012] The locking disc has an arc-shaped guide groove located below the docking port, and a docking connector located below the locking disc is also provided inside the outer shell; the docking connector is located directly below the docking port; one end of the guide groove is a large-diameter docking hole, and the other end is a small-diameter locking hole; the front end of the mechatronics integrated cone rod has a limiting rod with a diameter larger than the locking hole but smaller than the docking hole; the head of the mechatronics integrated cone rod has a first conductive pin, and the outer circumferential surface of the mechatronics integrated cone rod has a second conductive pin that elastically protrudes outward; a docking conductive spring is embedded in the inner circumferential surface of the small-diameter locking hole of the arc-shaped guide groove.
[0013] Furthermore, the docking mechanism is equipped with a power line carrier communication modem.
[0014] Furthermore, the docking connector is equipped with a pressure sensor; the mechatronics integrated cone rod is equipped with telecommunications connection contact points.
[0015] Furthermore, the driving device is a stepper motor, which has a linkage shaft. The linkage shaft has a limiting platform and a fixed flange mounting groove from bottom to top. The linkage slot is a protruding part on one side of the linkage shaft. The linkage shaft passes through the center hole of the locking plate from bottom to top and is locked with the locking plate through the linkage slot. The top of the stepper motor has an end connecting rod, which is coaxially connected to the linkage shaft.
[0016] Furthermore, the electromechanical integrated cone rod is equipped with a pin spring inside, and one end of the pin spring is in contact with the first conductive pin.
[0017] Furthermore, the outer shell includes a base plate and a surrounding plate extending vertically upward along the perimeter of the base plate. Both the surrounding plate and the base plate are provided with mounting holes. The base plate is also provided with copper pillars, positioning pins, docking connectors, and stepper motors.
[0018] In the next step, the docking mechanism also includes a fixed flange, locking bolts, a locking plate, a docking plate, a stepper motor, and a housing, all of which are provided with mounting holes. The copper pillars, locking bolts, and positioning pins respectively cooperate with the mounting holes, the fixed flange cooperates with the fixed flange mounting groove, and the limiting platform fixes each component.
[0019] Furthermore, the mechatronics integrated cone rod also includes a cone rod housing, with pin holes provided on the top and outer peripheral surfaces of the cone rod housing. The first conductive pin and the second conductive pin pass through the pin holes on the top and outer peripheral surfaces respectively from the inside to the outside.
[0020] Furthermore, the isomorphic docking mechanism is installed on a modular spacecraft that requires docking functionality.
[0021] To achieve the above objectives, the present invention provides a homogeneous integrated telecom interface component, which can adopt the following technical solution:
[0022] A homogeneous mechatronics docking assembly includes two such homogeneous mechatronics docking mechanisms. These two mechanisms are interlocked, with the mechatronics cone rods of each mechanism inserted into the other's docking slot. The limiting rod of the mechatronics cone rod passes through the large-diameter docking hole of the other's locking disc. A second conductive pin is always positioned in the other's guide groove. Rotation of the locking disc locks the small-diameter locking hole of the locking disc with the limiting rod of the other's mechatronics cone rod. The first conductive pin of the mechatronics cone rod is electrically connected to the other's docking connector. The second conductive pin of the mechatronics cone rod contacts the other's docking conductive spring.
[0023] The present invention has the following beneficial effects:
[0024] 1. The locking disc guide groove guides the cone rod to slide within the predetermined track, while the inclined surface design of the docking port on the docking disc shortens the docking time.
[0025] 2. The large docking tolerance is achieved by the docking socket with guiding function. When a deviation occurs during docking, the inclined surface of the docking socket applies a radial force to the tapered rod, causing the tapered rod shaft to realign with the docking socket.
[0026] 3. This invention integrates the originally separately connected mechanical locking interface, power transmission interface, and communication transmission interface into an integrated electromechanical-telecommunications docking mechanism. It uses a power line carrier communication modem and can realize electrical transmission, heat conduction, and power line carrier communication without the need for an additional telecommunications interface. The docking mechanism is designed in layers along the longitudinal direction to minimize the envelope size of the docking mechanism body, resulting in high integration and miniaturization.
[0027] 4. The negative electrode pin and locking plate negative electrode spring locking combination of the present invention, the positive electrode pin spring compressed by the positive electrode conductor, and the cone rod limiting rod and locking plate form a strict and tight mechanical connection. At the same time, it reduces the gap after docking and locking of the docking mechanism, improves the overall rigidity and strength of the mechanism, has low overall loss, and long reuse life.
[0028] 5. Repeatedly reduce the height of the cone rod to bring it close to the locking hole position and gradually compact it. In addition, the heterogeneous isomorphic docking mechanism itself has the advantage of high docking accuracy. Attached Figure Description

[0052] Please see Figures 6 to 7As shown, the conical rod housing 11 includes a limiting rod 17 and a locking rod 18. The protrusion on the top of the housing is the limiting rod 17, whose diameter is larger than the diameter of the locking hole 283 of the locking disc 28. The locking rod 18 is adjacent to the limiting rod 17 and is recessed, with a diameter slightly smaller than the diameter of the locking hole 283 of the locking disc 28. The diameters of both the limiting rod 17 and the locking rod 18 are smaller than the diameter of the mating hole 281. The top of the conical rod housing 11 is provided with a positive electrode pin hole 161, and the sides of the locking rod 18 are symmetrically provided with negative electrode pin holes 121. The positive electrode conductive pin 16 and the negative electrode conductive pin 12 pass through the positive electrode pin hole 161 and the side negative electrode pin hole 121 from the inside to the outside of the conical rod housing 11, respectively, so that the positive electrode conductive pin 16 is located at the top of the limiting rod 17, and the negative electrode conductive pin 12 is located at the locking rod 18.

[0053] Please see Figure 8 As shown, the stepper motor 24 has a linkage shaft 244, which has a limiting platform 241 and a fixed flange mounting groove 243 from bottom to top. The linkage slot 242 is a protruding part on one side of the linkage shaft 244. The end connecting rod 30 is located at the top of the stepper motor 24 and is coaxially connected to the linkage shaft 244. The end connecting rod 30 is used to prevent the linkage shaft 244 from being damaged by friction with the mating plate 21 when it rotates. The locking plate 28 has a hole in the center that matches the linkage shaft 244. The linkage shaft 244 with the locking plate linkage slot 242 passes through the hole in the locking plate 28 from bottom to top and is locked. At the same time, the fixed flange 26 is installed in the fixed flange mounting groove 243 and together with the limiting platform 241, fixes the stepper motor 24 to the locking plate 28. The negative conductive pin 12 at the limiting rod 17 engages with the groove on the inner surface of the guide groove 282 to achieve mechanical locking, so that the cone rod 1 slides along the guide groove 282 without disengaging. Stepper motor 24 drives locking disc 28 to rotate, realizing the conversion between the docking hole 281 and the locking hole 283 of tapered rod 1.
[0054] Please see Figures 11 to 12As shown, this invention discloses a homogeneous mechatronics integrated docking assembly 100-101, comprising two such homogeneous mechatronics integrated docking mechanisms 100. These two mechatronics integrated docking mechanisms 100 are interconnected, with the mechatronics integrated cone rods 1 of each mechanism inserted into the other's docking slots 35. The limiting rod 17 of the mechatronics integrated cone rod 1 passes through the large-diameter docking hole 281 of the other's locking disc 28. The second conductive pin is always located in the other's guide groove 282. Rotation of the locking disc 28 locks the small-diameter locking hole 283 of the locking disc 28 with the limiting rod 17 of the other's mechatronics integrated cone rod 1. The first conductive pin of the mechatronics integrated cone rod 1 is electrically connected to the other's docking connector. The second conductive pin of the mechatronics integrated cone rod 1 contacts the other's docking conductive spring.
[0055] In this embodiment, the docking mechanism 100 and the docked mechanism 101 are identical. The two docking mechanisms are mounted on modular spacecraft with docking functionality requirements. After the two spacecraft approach each other, the two sets of cone rods 1-docking ports 35 and docking holes 281 inside the docking mechanism 100 engage, achieving mechanical locking. Then, they enter the locking holes 283. After locking, the positive conductive pin 14 and negative conductive pin 12 of the docking mechanism 100 contact the positive conductive electrode 33 and negative spring 22 of the docked mechanism 101, respectively, to connect the power line. The power line carrier communication modem 29 operates, enabling inter-satellite communication in a low-voltage, high-frequency manner.
[0056] The docking assembly 100-101, which forms two sets of tapered rods 1 and docking ports 35, achieves docking and locking processes as follows. Please refer to [link / reference]. Figure 13 As shown, the two sets of docking mechanisms approach and dock along the axial direction of the two sets of conical rods 1. When a deviation occurs between the conical rod 1 of the docking mechanism 100 and the docked mechanism 101, the inclined surface of the docking port 35 of the docked mechanism 101 exerts a radial force on the conical rod 1, aligning the conical rod 1 with the docking port 35 and shortening the docking time. At the same time, the negative conductive pin 12 of the docking mechanism 100 contacts the docking plate 21 of the docked mechanism. The negative conductive pin 12 undergoes elastic deformation under pressure. Based on the heterogeneous isomorphic structure, at this time, the conical rods 1 of both the docking mechanism 100 and the docked mechanism 101 are subjected to the clamping force of the docking plate 28.
[0057] Please see Figure 14As shown, after the conical rod 1 enters the docking socket 35 and exerts a clamping effect, the conical rod 1 moves further into the docking socket 35. The positive conductive pin 16 of the docking mechanism 100 contacts the positive conductive device 33 of the docking mechanism 101, and the pin spring 14 of the docking mechanism 100 is passively compressed. At the same time, the negative conductive pin 12 of the docking mechanism 100 contacts the locking disc 28 of the docking mechanism 101, and the negative conductive pin 12 undergoes elastic deformation under pressure. The spring structure of the pin spring 14 and the negative conductive pin 12 presses the contacts of the positive conductive pin 16 and the negative conductive pin 12 of the docking mechanism 100 with the negative spring 22 of the locking disc and the positive conductive device 33 of the docking main module 2 of the docking mechanism 101.
[0058] Please see Figure 15 As shown, after the pressure sensor 37 built into the positive electrode conductor 33 detects that the positive electrode conductive pin 16 has fully entered the docking hole 281 of the docking socket, the negative electrode conductive pin 12 engages with the groove on the inner surface of the guide groove 282 of the locking disc 28 to achieve locking. At the same time, based on the diameter matching, the limiting rod 17 plays a mechanical locking role with the guide groove 282 in the vertical direction, and the two spacecraft achieve a tight connection. Afterwards, the gap after docking and locking of the docking mechanism 100 is reduced, and the stepper motor 24 drives the locking disc 28 to rotate through the linkage shaft 244. The negative electrode conductive pin 12 slides in the guide groove 282 of the locking disc 28 within the docking socket 35 without disengaging, so that the cone rod 1 enters the locking hole 283 to complete the locking. Subsequently, the positive conductive pin 16 contacts the positive conductive device 33, and the negative conductive pin 12 contacts the negative spring 22 to connect the power transmission line. The power line carrier modem 29 operates, modulates the electrical signal and transmits it, and performs inter-satellite communication in the form of low voltage and high frequency.
[0059] In this system, the two sets of negative conductive pins 12 of the two docking mechanisms are locked together with the negative spring plate 22 of the locking disc. The pin spring 14, compressed by the positive conductor 33, and the cone-shaped limiting rod 17 are then mechanically connected to the locking disc 28. This reduces the gap after the docking mechanism 100 is locked, improving the overall rigidity and strength of the mechanism to meet the needs of docking or rapid separation under extreme working conditions. The use of a power line carrier communication modem 29 enables electrical transmission, heat conduction, and power line carrier communication without the need for an additional telecommunications interface.
[0060] This invention, based on the conical rod docking method and combined with a highly integrated electromechanical-telecommunications design, proposes a homogeneous modular docking mechanism design with rapid docking, separation, and locking capabilities, featuring electrical and telecommunications transmission functions. The mechanism boasts a simple structure. This invention enables docking / disconnection, locking / unlocking, power-on / power-off, and power line carrier communication / disconnection for multiple spacecraft. By applying this modular, homogeneous docking mechanism to a satellite, it facilitates rapid assembly and separation of spacecraft; disassembly and maintenance of functional modules; transformation and reconstruction of satellite configurations; centralized and distributed energy distribution between spacecraft; and centralized processing and distributed data transmission between satellites.
[0061] In summary, the isomorphic telecom integrated docking mechanism and docking components of this invention have the characteristics of high precision, high integration, miniaturization, short docking time, and high docking fault tolerance.
