In order to solve the foregoing technical problems, as shown in fig. 1, an electromagnetic locking and separating device 100 for micro-nano satellite docking is provided, which may include one or more electromagnetic locking and separating blocks 110 and a power controller 120. The electromagnetic locking and separating block 110 may be installed outside the micro-nano satellite and exposed, the electromagnetic locking and separating block 110 may be parallel or protruding with respect to the outer surface of the micro-nano satellite, and the power controller 120 may be installed inside the micro-nano satellite for docking, locking and separating between the plurality of micro-nano satellites.
By arranging the electromagnetic locking and separating device 100 for docking the micro-nano satellites, the power controller 120 is used for controlling the electromagnetic locking and separating block 110 to obtain magnetism, so that the micro-nano satellites are docked and locked; the electromagnetic locking separation block is controlled by the power controller 120 to lose magnetism, so that the micro-nano satellites are separated, the electromagnetic locking separation device 100 is simple in structure, the point-to-point type butt joint mode is simplified into the butt joint mode between the face to face of the electromagnetic locking separation block 110, the work is convenient and quick during butt joint, locking and separation, the control difficulty of the micro-nano satellite butt joint is reduced, and the efficiency of the micro-nano satellite butt joint work is effectively improved.
Wherein, one or more electromagnetic locking and separating blocks 110 can be installed outside the micro-nano satellite and used for being in butt joint with the electromagnetic locking and separating block 110 of another micro-nano satellite; the electromagnetic locking separation block 110 may include: a magnet block 111, an exciting coil 112; the exciting coil 112 may surround the outside of the magnet block 111; the magnet block 111 can be magnetized or demagnetized by switching the current in the exciting coil 112. The electromagnetic locking separation blocks 110 can be one or more, can be arranged on the outer side of the micro-nano satellite, the electromagnetic locking separation blocks 110 can be arranged on one side of the micro-nano satellite, and are in butt joint with the electromagnetic locking separation blocks 110 of another micro-nano satellite, and the butt joint efficiency can be improved by simultaneously working the electromagnetic locking separation blocks 110. As shown in fig. 5, a plurality of electromagnetic locking and separating blocks 110 may also be installed on different sides of the micro-nano satellite, so as to dock with the electromagnetic locking and separating blocks 110 on a plurality of other micro-nano satellites, thereby realizing docking of a plurality of micro-nano satellites. The magnet block 111 may be columnar, hoof-shaped or bar-shaped, and the like, the exciting coil 112 surrounds the outside of the magnet block 111, and the exciting coil 112 may surround the magnet block for a plurality of turns. The magnet block 111 is magnetized or demagnetized by switching current in the exciting coil 112.
In some embodiments, the plurality of electromagnetic locking separation blocks 110 are uniformly distributed or diagonally distributed on the outer side of the micro-nano satellite, and the magnetic poles of the plurality of electromagnetic locking separation blocks 110 facing the outer side of the micro-nano satellite may be N poles or S poles. When the micro-nano satellites are in butt joint, the magnetic poles of the two micro-nano satellite electromagnetic locking separation blocks 110 need to be mutually adsorbed correspondingly, so that the magnet blocks 111 with different magnetic pole directions can be obtained by arranging the exciting coils 112 with different winding directions, and the magnetic pole directions of the electromagnetic locking separation blocks 110 in the working state are changed; the current direction of the electromagnetic lock separation block 110 in the operating state can be changed by supplying currents in different directions to the exciting coils 112 of the same winding direction to thereby obtain the magnet blocks 111 of different magnetic pole directions. When the micro-nano satellites are in butt joint, the plurality of electromagnetic locking separation blocks 110 can be uniformly distributed on the outer sides of the micro-nano satellites, when the two outer sides of the micro-nano satellites are close to each other in butt joint, the magnetic force among the plurality of electromagnetic locking separation blocks 110 can be used for self-alignment, the requirements for high-precision navigation and control in the butt joint process are reduced, the butt joint mode is simplified, and the butt joint efficiency is improved. As shown in fig. 4, the plurality of electromagnetic locking separation blocks 110 may be distributed on the outer sides of the micro-nano satellites in a diagonal manner, and when the two micro-nano satellites are in butt joint, the outer sides of the two micro-nano satellites are close to each other, and the plurality of electromagnetic locking separation blocks 110 on the diagonal line are used for self-alignment, butt joint and locking. The two satellites move stably in the butt joint process through the diagonal arrangement of the electromagnetic locking separation blocks 110, so that the force is stable during butt joint, and the positioning is more accurate.
In some embodiments, the magnet block 111 may be an electromagnet, when the exciting coil 112 is connected with current, a magnetic line of force passes along the center of the exciting coil 112, so that the center magnet block 111 is magnetized, and the electromagnetic locking separation block 110 is in a working state and has magnetism, so that the magnetic locking separation block can be in butt joint and locking with another electromagnetic locking separation block 110; when the current in the exciting coil 112 is disconnected, the magnetic force lines along the center of the exciting coil 112 disappear, the magnet block 111 is demagnetized, and at this time, the electromagnetic locking and separating block 110 is in a non-working state and is non-magnetic and separated from the corresponding electromagnetic locking and separating block 110. By arranging the electromagnetic locking separation block 110, the docking, locking and separation of the micro-nano satellite can be rapidly completed after the power is turned on and off, and the docking efficiency of the micro-nano satellite is effectively improved.
In some embodiments, the magnet block 111 may be an electro-permanent magnet and the magnet block 111 may be an inorganic non-metallic magnetizer. When the magnet block 111 has no magnetism, the exciting coil 112 is connected with current, and magnetic force lines pass along the center of the exciting coil 112 to magnetize the magnet block 111 at the center, and at the moment, the electromagnetic locking and separating block 110 is in a working state and has magnetism, so that the electromagnetic locking and separating block 110 can be in butt joint and locking with another electromagnetic locking and separating block 110; at this time, the current is cut off, and the electro-permanent magnet can still maintain magnetism and continuously be locked with the other electromagnetic locking separation block 110. When the magnet block 111 has magnetism, a reverse current is conducted to the exciting coil 112, magnetic lines of force disappear, the central magnet block 111 is demagnetized, the electromagnetic locking and separating block 110 is in a non-working state, the electromagnetic locking and separating block 110 can be separated from another electromagnetic locking and separating block 110 without magnetism, and the current is disconnected, and at the moment, the electromagnetic locking and separating block 110 continues to keep in a non-magnetic state and still is separated from the other electromagnetic locking and separating block 110. By arranging the electromagnetic locking separation block 110 of the electro-permanent magnet, the magnetism of the electromagnetic locking separation block 110 can be continuously kept after short-term energization, the energization state is not required to be kept in the docking and locking process of the micro-nano satellite, and the energy loss in the docking process of the micro-nano satellite is effectively reduced.
The power supply controller 120, the power supply controller 120 can be arranged inside the micro-nano satellite and electrically connected with the exciting coil 112, and the power supply controller 120 controls the on-off and the direction of the current in the exciting coil 112. The power controller 120 may be an adjustable independent power source, and can independently provide current for the exciting coil 112, and control on/off of the current, so as to control whether the magnetism of the electromagnetic locking separation block 110 exists. The power controller 120 may also be a switch controller, which is connected to the internal circuit of the micro-nano satellite, and controls the on-off of the current flowing to the exciting coil 112 in the satellite through the on-off operation of the power controller 120, so as to realize the control on the magnetism of the electromagnetic locking separation block 110. For the electromagnetic locking and separating block 110 of the electromagnet, when the power supply controller 120 is switched on, current flows in the exciting coil 112, the electromagnetic locking and separating block 110 has magnetism, the power supply controller 120 is kept on, the current continuously flows, and the electromagnetic locking and separating block 110 keeps magnetism; when the power controller 120 is turned off, no current flows in the exciting coil 112, and the electromagnetic lock release block 110 loses magnetism. The power controller 120 may also change the direction of the current, thereby changing the magnetic poles of the electromagnetic lock release block 110. When the electromagnetic locking separation block 110 is in a non-magnetic state, the power supply controller 120 is connected to transmit forward current, and the forward current flows in the exciting coil 112, at this time, one end of the electromagnetic locking separation block 110, which faces the outer side of the micro-nano satellite, is an S pole, and the other end is an N pole; when the electromagnetic locking and separating block 110 is in a non-magnetic state, the power supply controller 120 is connected to deliver reverse current, and the reverse current flows in the exciting coil 112, so that the magnetic poles of the electromagnetic locking and separating block 110 are opposite, one end facing the outer side of the micro-nano satellite is an N pole, and the other end is an S pole. The power controller 120 may also control the presence or absence of magnetism of the electro-permanent magnet type electromagnetic lock separation block 110 by changing the current direction. For the electromagnetic locking separation block 110 of the electro-permanent magnet type, when the power controller 120 is switched on in the non-magnetic state of the electromagnetic locking separation block 110, current flows in the exciting coil 112, the electromagnetic locking separation block 110 has magnetism, the power controller 120 is closed, the electromagnetic locking separation block 110 still keeps magnetism, the power controller 120 is opened again, current in the same direction is transmitted, and the magnetism of the electromagnetic locking separation block 110 is kept unchanged; in the magnetic state of the electromagnetic locking and separating block 110, the power supply controller 120 is started to transmit reverse current, and the magnetism of the electromagnetic locking and separating block 110 disappears. The electromagnetic locking and separating device 100 for micro-nano satellite docking is controlled by the power controller 120 to realize locking and separating operation, so that the control difficulty of micro-nano satellite docking is reduced.
By arranging the electromagnetic locking and separating device 100 for micro-nano satellite docking, the power controller 120 is used for controlling the magnetism of the electromagnetic locking and separating block 110 to realize the locking and separating of the electromagnetic locking and separating block 110, so that docking, locking and separating among micro-nano satellites are realized, the docking is more convenient and rapid, and the efficiency of micro-nano satellite docking work is improved. The electromagnetic locking and separating device 100 for micro-nano satellite docking has a simple structure, simplifies a point-to-point docking mode into a docking mode between the faces of the electromagnetic locking and separating blocks 110, has certain gesture autonomous adjustment capability, does not need high-precision active control during micro-nano satellite docking, can realize self-alignment of the docking process through magnetic attraction between the electromagnetic locking and separating blocks 110, simplifies the preparation work of micro-nano satellite docking, reduces the control difficulty of micro-nano satellite docking, and reduces the power consumption of micro-nano satellite docking and locking.
