Description

Technical Field

[0001] The present invention relates to the field of electromagnetic connection technology, and in particular to a satellite module rapid docking and separation structure and a use method thereof. Background Art

[0002] Satellites typically adhere to a one-satellite-one-design principle during the design, production, assembly, and testing stages. Each component, module, and interface has its own unique installation method. Even for two or more satellites with the same design, the interface design of the entire satellite or its components often struggles to accommodate rapid assembly during assembly. The interface between the payload and the satellite's cabin often utilizes screw connections. First, the payload is positioned in the mounting configuration through locating holes, and then screws are installed through multiple mounting holes. This is especially true for large payloads, and assembly time between the payload and the entire satellite can take upwards of two days, leading to excessively long satellite production cycles. With the rapid development of aerospace technology in recent years, the number of mass-produced satellites, such as Starlink and constellation satellites, has increased, leading to an increasing number of spacecraft rendezvous and docking missions. Universal docking and separation methods struggle to meet the rapid integration requirements of mass-produced satellites.

[0003] Currently, research at home and abroad is focused on electromagnetic docking in space. Limited research exists on the ground assembly phase of satellites, and most utilize electromagnetic coils, which are complex, have limited load-bearing capacity, and consume a lot of energy. Given the short production cycles, low costs, and high volume of mass-produced satellites, it is imperative to break away from traditional satellite interface configurations and break through existing assembly technologies to improve assembly efficiency and reduce assembly time. Therefore, considering the requirements for rapid satellite assembly and separation, combined with the satellite's need for environmental adaptability, a technology for rapid satellite module docking and separation is urgently needed. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems and to propose a satellite module rapid docking and separation structure and a method of use.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

The heating plate and the magnet array are embedded in the second groove. The positioning bolt is located at the end of the first adapter block near the daughter body.

[0007] The sub-body is provided with a transfer block 2 and an iron-nickel block. The transfer block 2 is in the shape of a truncated cone on the side close to the mother body, which matches the groove 1. The transfer block 2 is in the shape of a cylinder on the side away from the mother body. The transfer block 2 is provided with a rectangular groove 3 on the end close to the mother body, and the iron-nickel block is embedded in the groove 3.

[0008] Preferably, the magnet array is provided with five rectangular parallelepiped magnetic blocks, the five magnetic blocks are in the same orientation and bonded sequentially from left to right, and the magnetization directions of the five magnetic blocks are top, left, bottom, right, and top from left to right.

[0009] Preferably, the mother body is connected to the satellite via a first adapter block, and the daughter body is connected to the docking module via a second adapter block.

[0010] Preferably, the heating sheet is made of a thin sheet of material with heat conduction function, one side of the heating sheet is bonded to the magnet array, and the other side is passed with current.

[0011] Preferably, the iron-nickel block is made of an alloy material made of iron and nickel and has magnetic properties.

[0013] S1, connecting the adapter block 1 of the mother body to the satellite, with the groove 1 facing the daughter body, and connecting the adapter block 2 of the daughter body to the docking module, with the side embedded with the iron-nickel block facing the mother body;

[0014] S2, open the positioning bolt on the mother body, align the end of the child body close to the mother body with the groove on the mother body, and after the mother body and the child body are attracted and closed, close the positioning bolt on the mother body to complete the docking;

[0015] S3. Utilize the heating plate on the mother body to heat the magnet array, and open the positioning bolt at the same time. When the magnet array is heated to a predetermined temperature, the magnetic attraction is lost, and the daughter body automatically falls off, completing the separation.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

The rapid docking and separation structure of the present application has low production cost, simple structure, short cycle, and can be mass-produced; it has high reliability, strong bearing capacity, and low energy consumption; through the docking and separation between the parent body and the child body, the docking and separation speed of the present structure is fast, the assembly efficiency is high, and it can be repeatedly and quickly disassembled; it can meet the needs of docking and separation, assembly, transportation, testing and other processes of various products, facilities and instruments in space, at sea and on land, and has a wide range of uses; the present application adopts a magnetic array structure with no matrix design, which will not produce magnetic effects on surrounding components.

The end of the transfer block 1 near the daughter body is provided with a truncated cone-shaped groove 7, and the narrower end of the groove 7 is provided with a rectangular parallelepiped groove 2 8. The heating plate 3 and the magnet array 2 are embedded in the groove 2 8. The positioning bolt 4 is located at the end of the transfer block 1 near the daughter body. The positioning bolt 4 is made of a relatively rigid material and is used to prevent the mother body and daughter body from falling off after docking.

[0025] The sub-body is provided with a transfer block 2 5 and an iron-nickel block 6. The transfer block 2 5 is in the shape of a truncated cone on the side close to the mother body, which matches the groove 1 7. The transfer block 2 5 is in the shape of a cylinder on the side away from the mother body. The diameter of one end of the cylinder is smaller than the diameter of the large circular surface of the truncated cone, which is conducive to the installation of the mother body positioning bolt 4. The transfer block 2 5 is provided with a rectangular groove 3 9 on the end close to the mother body, and the iron-nickel block 6 is embedded in the groove 3 9.

[0026] Specifically, such as Figure 2 As shown, the magnet array 2 is provided with five rectangular parallelepiped magnetic blocks, which are in the same orientation and bonded sequentially from left to right.
