Background

In the prior art, the rocker is mostly formed on the basis of the rotation of a rotor of a motor, and various power transmission mechanisms are matched on a rotating shaft of the motor to output power. In general, the motor power mechanism can only adjust the rotation direction, namely forward rotation and reverse rotation, and the rotation speed and the rotation torque. The motor rotor is fixed, the moving direction of the rotor cannot be adjusted, and if a rocking bar power mechanism capable of rocking is to be generated, the rotor must be matched with a mechanical power mechanism. However, the formed rocker power mechanism is complex, the swing track is fixed, the rocker is inflexible, and the swing direction, the swing moment and the speed of the rocker cannot be controlled at any time. The motor-based power device cannot be applied to a high-requirement rocker power device and cannot meet high-precision and multi-dimensional rocker control.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: a rocker structure based on electromagnetic induction comprises a mechanical part 100 and an electronic part 200; the mechanical part 100 comprises a base 1; the base 1 is a hemispherical shell, and a fixed shaft 2 is rotatably arranged at an opening of the base 1 along the radial direction; a rocker 3 is arranged at the center of the fixed shaft 2 in a spherical hinge mode; the bottom of the rocker 3 faces the inside of the base 1, and the bottom surface of the rocker is provided with a permanent magnet; the surface of the base 1 is uniformly provided with a plurality of soft magnets 4, and the polarity opposite surfaces of the soft magnets 4 and the permanent magnets face the center of the base 1; a control lead 5 is wound outside the soft magnet 4; the electronic part 200 comprises a control MCU 6; the control MCU 6 is electrically connected with the current control interfaces 7, and the current control interfaces 7 are electrically connected with the control wires 5 through connecting wires 8; the control MCU 6 is electrically connected with the communication interface 9.

The rocker 3 is of a conical structure with a small upper part and a large lower part, the permanent magnet is mounted in the center of the bottom surface of the rocker 3, the upper part of the permanent magnet is connected with an external execution part, the bottom of the permanent magnet is used for increasing the mounting area of the permanent magnet, and the surfaces with different polarities of the permanent magnet are prevented from being exposed in the base 1.

The hinged part 10 of the fixed shaft 2 and the rocker 3 is positioned at the sphere center of the base 1, so that the rocker 3 rotates around the center of the base 1 in the base 1.

The control lead 5 is positioned on the outer side of the base 1, so that the situation that the motion space of the rocker 3 is blocked due to the fact that the control lead 5 and the connecting lead 8 are connected on the inner side of the base 1 is avoided, and the influence on the motion of the permanent magnet is avoided due to the fact that a magnetic field generated by the control lead 5 and the connecting lead 8.

Preferably, the magnetic field polarity of the permanent magnet facing the base 1 is an N pole, when most of the magnetic poles of the soft magnets 4 are S poles, and the magnetic poles of the soft magnets 4 at other positions are N poles, the rocker 2 is fixed at the position where the magnetic poles are S poles, and when the polarity S pole of the soft magnet 4 facing the permanent magnet of the rocker 2 changes along a certain path, the rocker 2 also moves along the predetermined path under the interaction between the permanent magnet and the soft magnet 4 to swing.

The using method comprises the following steps: when the control MCU 6 of the electronic part 200 obtains a control signal from an upper computer through the communication interface 9, the calculation is performed first, and then a control instruction of the current direction is sent, and at this time, the plurality of current control interfaces 7 output current through the corresponding connecting wires 8. When the control lead 5 passes through current, the corresponding polarity of the inner side of the soft magnet 4 is different from the polarity of the permanent magnet arranged at the bottom of the rocker 3, and the rocker 3 is driven and kept at the position. When the current on each of the control conductors 5 changes direction, the polarity of the corresponding ones of the soft-magnetic bodies 4 also changes. In all the soft magnets 4, when the magnetic field polarity inside the soft magnet 4, which is different from the polarity of the permanent magnet, moves in a certain path, the rocking bar 3 swings in a certain path under the interaction between the permanent magnet and the soft magnet 4. When the rocker 3 swings, the permanent magnet at the bottom of the rocker 3 passes through the soft magnet 4, and a back electromotive force is generated on the control lead 5 surrounding the soft magnet 4, so that the position of the rocker 3 can be known through the voltage sampling interface, and the position of the rocker 3 can be accurately operated and controlled.
