The rotating shaft A11, the rotating shaft B12, the movable arm A2, the movable arm B3, the support frame 4 and the frame 1 are all made of aluminum alloy materials, specifically 7 series aluminum alloy. The aluminum alloy material is selected, the whole weight of the pushed carrier 5 cannot be increased due to light material, and meanwhile, the aluminum alloy material is not magnetic and is not easily influenced by various electromagnets or permanent magnets, so that the stable operation of the electromagnetic thruster is ensured; and the movable arm A2 and the movable arm B3 are both of an outer side surface plane structure and an inner side surface conical structure, so that the resistance of the movable arm A2 and the movable arm B3 when the movable arm A is switched from the initial state to the unfolding state is larger than the resistance when the movable arm A is switched from the unfolding state to the initial state.

As shown in fig. 5, K is a circuit main switch of the electromagnetic thruster; beta is the instant switch contact of the branch circuit of the first electromagnet A21 and the first electromagnet B31, the second electromagnet A22 and the second electromagnet B32; phi is an instant switch contact of a branch circuit of the third electromagnet A23 and a branch circuit of the third electromagnet B33, and contact pieces at two ends of the instant switch contact phi of the branch circuit of the third electromagnet A23 and the branch circuit of the third electromagnet B33 are respectively connected with an extension plate of the movable arm A2 and an extension plate of the movable arm B3 on the corresponding side;

firstly 1 and firstly 2 are respectively two current regulators in a branch circuit of a first electromagnet A21 and a first electromagnet B31, a branch circuit of a second electromagnet A22 and a second electromagnet B32, and a branch circuit of a third electromagnet A23 and a third electromagnet B33, and the current regulators are used for regulating the current of two branches, so that the instant speed when the second electromagnet A22 is bounced off from the second electromagnet B32 and the instant speed when the second electromagnet A22 is reset from the second electromagnet B32 by the action of the third electromagnet A23 and the third electromagnet B33 are equal to or slightly greater than the instant speed when the second electromagnet A22 and the second electromagnet B32 return to the first electromagnet A21 and the first electromagnet B31, and the instant speed when the second electromagnet A21 and the first electromagnet B31 are bounced off from the second electromagnet A22 and the second electromagnet B32;

when the first permanent magnet a24 and the first permanent magnet B34 are turned off, the initial state of the electromagnetic thruster, that is, the reset state is maintained, and the circuit at the immediate switch contact β of the branch circuit of the first electromagnet a21 and the first electromagnet B31, and the branch circuit of the second electromagnet a22 and the second electromagnet B32 is maintained in the on state.

The working principle of the electromagnetic thruster is as follows: as shown in fig. 5, when the circuit main switch K is closed, equal-strength electromagnetic repulsion forces are simultaneously generated between the first electromagnet a21 and the second electromagnet a22, and between the first electromagnet B31 and the second electromagnet B32, respectively, because the magnetic strength generated by the first electromagnet a21 and the second electromagnet a22 in the initial state is much greater than that generated by the second electromagnet a22 and the second electromagnet B32, and the first electromagnet a21 and the first electromagnet B31 are fixed on the pushed carrier 5, the second electromagnet a22 and the second electromagnet B32 are instantly bounced off by the equal-strength electromagnetic repulsion forces generated by the first electromagnet a21 and the first electromagnet B31, and at this time, the β contact is separated and de-energized, so that the β contact swings at the angular speed of W with the rotating shaft a11 and the rotating shaft B12 as the axes, and because the arrangement of the first arc-shaped strip and the second arc-shaped strip of the electromagnetic thruster is limited so that the swing angle does not exceed 45 degrees,

as shown in fig. 1, in the process of switching to the state of fig. 3, when the movable arm a2 and the movable arm B3 swing to the unfolded state, the Φ contact circuit is turned on, at this time, a strong electromagnetic repulsion force is generated between the third electromagnet a23 and the third electromagnet B33, and under the combined action of the permanent magnetic repulsion force generated between the second permanent magnet a25 and the second permanent magnet B35, the movable arm a2 and the movable arm B3 swing to be rapidly decelerated to zero and swing in the opposite direction at an angular velocity equal to or slightly greater than w, at this time, the Φ contact is separated and powered off, the movable arm a2 and the movable arm B3 swing forward in inertial synchronization symmetry, when the second electromagnet a22 and the second electromagnet B32 are about to contact with the first electromagnet a21 and the first electromagnet B31, the β contact circuit is turned on, the first electromagnet a21 and the second electromagnet a22, and the first electromagnet B31 and the second electromagnet B32 generate an equal-strength electromagnetic repulsion force; the operation principle is repeated, so that the movable arm A2 and the movable arm B3 perform reciprocating swing, and the pushed carrier 5 is accelerated to move forwards under the action of the electromagnetic thruster;

because the factors such as the kinetic friction energy consumption of the rotating shaft a11 and the rotating shaft B12 exist in the process of back-and-forth swinging, and if the third electromagnet a23 and the third electromagnet B33 are permanent magnets, considerable energy loss is certainly caused in the process of energy conversion of the rotating shaft from deceleration to zero adjustment, and an instant electromagnetic repulsion force cannot be provided for the rotating shaft of the movable arm a2 and the rotating shaft of the movable arm B3 to rotate to the initial state, the third electromagnet a23 and the third electromagnet B33 must be electromagnets to perform energy compensation so that the instant speed of the second electromagnet a22 and the second electromagnet B32 to return to the initial state is equal to or slightly greater than the instant speed of the bouncing off by the first electromagnet a21 and the first electromagnet B31.

Example 2

The present embodiment is substantially the same as embodiment 1, and is different from embodiment 1 in that, as shown in fig. 8 and 9, 24 sets of electromagnetic thrusters may be arranged on the pushed carrier 5 at equal angles, and are used for controlling the electromagnetic thrusters arranged at corresponding angles to perform steering and other control, where the electromagnetic thrusters are provided with 24 sets of electromagnetic thrusters, and the 24 sets of electromagnetic thrusters are arranged on the pushed carrier 5 at an angle of 15 degrees; through the above 24 groups of annular distribution modes, the differential interval can be divided into 3 groups, so that the differential interval has two groups of standby groups and one group of working groups, and the differential interval can be switched periodically or switched by another group when a group of faults occur in the actual use process, thereby ensuring the continuous operation of the thrust action, and the service life of each electromagnetic thruster can be effectively prolonged by adopting the arrangement of the two groups of standby groups and the working group.

Example 3

The present embodiment is substantially the same as embodiment 1, and is different from embodiment 1 in that, as shown in fig. 10 and 11, 24 sets of electromagnetic thrusters may be arranged on the pushed carrier 5 at equal angles, and are used for controlling the electromagnetic thrusters arranged at corresponding angles to perform steering and other control, the electromagnetic thrusters are arranged in 3 × 8 sets, each 8 sets is a ring distributed on the pushed carrier 5 from inside to outside, and 8 sets of electromagnetic thrusters of each ring are arranged at equal angles of 45 degrees; through the mode of the three-ring distribution of the 3 x 8 groups, the three-ring-shaped thrust thruster is provided with two groups of standby groups and one group of working groups, and can be switched periodically or when one group of working groups fails, so that the thrust action can be continuously operated, and the service life of each electromagnetic thruster can be effectively prolonged by adopting the arrangement of the two groups of standby groups and the one group of working groups.
