The rotary hole 141 is circular in shape, and the rotary shaft 13 is circular in cross-sectional shape, and the rotary shaft 13 is inserted into the rotary hole 141 and is rotatable in the rotary hole 141 by an external torque.

It is understood that the magnetic field change signal comprises a change in the direction of the magnetic field and/or a change in the strength of the magnetic field.
Referring to fig. 4 to 5, the particle building block type modular magnetic control coupling 100 provided in the embodiments of the present application includes a housing, a circuit board 14, a rotating shaft 13, a magnetic member 135, a main control unit 144 and a magnetic induction sensor 145, where the particle building block type modular magnetic control coupling 100 is disposed outside the micro motor 2, so that any micro motor 2 can be converted into a steering engine through combination with the particle building block type modular magnetic control coupling 100, and then any micro motor 2 can be changed into a special micro motor 2 for precisely controlling and monitoring the rotation angle of the end of a transmission chain by the particle building block type modular magnetic control coupling 100.

Referring to fig. 4 to 5, it can be understood that the main control unit 144 can compare and correct the rotation angle of the micro motor 2 with the actually monitored rotation angle of the micro motor 2, so as to further improve the control accuracy of the main control unit 144 on the rotation angle of the micro motor 2. For example, the actual rotation angle of the micro motor 2 is too small, and the main control unit 144 may increase the rotation angle of the micro motor 2 by a command.
Optionally, the main control unit 144 is a main control MCU, which refers to a short for the main controller microcontroller unit (Main Control Unit Microcontroller Unit). Which is an integrated circuit chip that integrates a processor core, memory, input/output interfaces, and other functional modules.
Referring to fig. 4-5, magnetic induction sensor 145 (Magnetic Induction Sensor) is optionally a sensor for measuring and detecting magnetic field strength and direction. Based on the magnetic induction principle, the method outputs corresponding electric signals by sensing the change of the surrounding magnetic field.
Magnetic induction sensors are typically composed of a magnetic sensing element, a signal processing circuit and an output interface. The magneto-sensitive element may be a magneto-resistive effect sensor (e.g. magneto-resistive sensor, hall sensor) or a magneto-inductive inductor (e.g. magneto-inductive coil). When the surrounding magnetic field changes, the magneto-sensitive element generates a corresponding electric signal.
Referring to fig. 4 to 5, when the micro motor 2 is started and outputs a rotation moment, the rotation shaft 13 starts to rotate, and thus the magnetic member 135 rotates. The magnetic field at the location of the magnetic induction sensor 145 will also change due to the rotation of the magnetic member 135. The magnetic field of the magnetic element 135 can be monitored by a magnetic induction sensor 145. The magnetic induction sensor 145 is located on the circuit board 14, and the magnetic field change at the location thereof can be converted into an electric current, thereby converting the magnetic field change into an electric signal, and then transmitted to the main control unit 144. After receiving the magnetic field change signal from the magnetic induction sensor 145, the main control unit 144 calculates the rotation angle of the micro motor 2 according to the magnetic field change signal.
Referring to fig. 3 to 4, in some embodiments, the magnetic member 135 is annular, and the magnetic member 135 is sleeved on the rotating shaft 13.
It can be understood that, by arranging the annular magnetic member 135 on the rotating shaft 13, the change of the magnetic field of the magnetic member 135 reflects the rotation condition of the rotating shaft 13, so that the particle building block type modular magnetic control coupling 100 monitors the rotation angle of the micro motor 2 actually transmitted to the rotating shaft 13, and the monitoring precision of the particle building block type modular magnetic control coupling 100 is improved.
Referring to fig. 4 to 6, alternatively, the magnetic member 135 is a ring-shaped magnet, and the magnetic member 135 is sleeved on the rotating shaft 13 and rotates synchronously with the rotating shaft 13. The magnetic member 135 may be a permanent magnet, a magnetostatic body, or a permanent magnet, but is not limited thereto, and is selected according to practical circumstances.
In this embodiment, the magnetic member 135 is a permanent magnet, which is a material capable of permanently maintaining its own magnetism. Unlike temporary magnets (e.g., electromagnets), permanent magnets do not require an external power source or current to generate a magnetic field, and they have their own inherent magnetism. Permanent magnets are typically made of specific magnetic materials such as neodymium iron boron (NdFeB), cobalt steel (Alnico), iron cobalt boron (FeCoB), ferrite (Ferrite), and the like.
Referring to fig. 3 to 4, in some embodiments, a limiting shoulder 133 is protruding from a side surface of the rotating shaft 13, and the magnetic member 135 is located between the circuit board 14 and the limiting shoulder 133.
It can be appreciated that the magnetic member 135 can be prevented from moving along the axial direction of the rotation shaft 13 by the limiting shoulder 133, so that the reliability of the connection between the magnetic member 135 and the rotation shaft 13 is improved.

The magnetic member 135 may be a permanent magnet, a magnetostatic body, or a permanent magnet, but is not limited thereto, and is selected according to practical circumstances. The columnar magnetic element 135 is divided into two parts along the axial direction of the rotating shaft, the first part 1351 is an S pole, the second part 1352 is an N pole, the first part 1351 and the second part 1352 are both positioned in the rotating shaft 13, and the first part 1351 and the second part 1352 are butted to form the columnar magnetic element 135, so that the convenience of assembling the magnetic element 135 and the rotating shaft 13 is improved, and a magnetic induction line is emitted from the N pole and returns to the S pole, so that the magnetic field at the position of the magnetic induction sensor 145 can be changed in the rotating process of the rotating shaft 13.
In some embodiments, two magnetic induction sensors 145 are provided, and the two magnetic induction sensors 145 are arranged at intervals along the circumferential direction of the rotary hole 141.
