In the embodiment of the disclosure, the third direction current and the fourth direction current may be opposite currents, and the third magnetic field direction and the fourth magnetic field direction may be opposite magnetic fields.
It should be noted that the control circuit can generate the current in the opposite direction to make the third coil generate the magnetic field in the opposite direction, so as to generate the magnetic force in the opposite direction. Based on the magnetic force in the opposite direction, the moving body 1002 can be driven to move on the second guide rail 1001b in the opposite direction, and then the moving direction of the moving body 1002 on the second guide rail 1001b can be controlled through the direction of the current, so that the purpose of accurately controlling the moving direction of the moving body 1002 through electromagnetic conversion is achieved.
In one embodiment, as shown in FIG. 5, the fourth magnetic assembly 2004, is further configured to generate a magnetic field having a third magnetic field strength based on a third current strength in the third coil;
the second magnetic assembly 1002a drives the moving body 1002 to move along the second guide rail 1001b by a third angle under the action of a magnetic field with a third magnetic field intensity;
alternatively, the first and second electrodes may be,
a fourth magnetic assembly 2004, further for generating a magnetic field having a fourth magnetic field strength based on a fourth current strength in the third coil;
the second magnetic assembly 1002a drives the moving body 1002 to move along the second guide rail 1001b by a fourth angle under the action of a magnetic field with a fourth magnetic field intensity;
wherein the third angle is different from the fourth angle.
It can be understood that the control circuit generates currents with different current intensities and different directions, so that the third coil generates magnetic fields with different magnetic field intensities and different magnetic field directions, and further generates magnetic forces with different directions and different sizes, and the moving body 1002 is driven to move to different directions at different angles along the second guide rail 1001b, so that the moving direction and the moving angle of the moving body 1002 can be accurately controlled, and the optical signal generated by the moving body 1002 can cover the target object, and the acquisition blind area is reduced.
In an embodiment, as shown in fig. 6, the terminal device further includes:
the fifth magnetic assembly 2005, which is disposed opposite to the fourth magnetic assembly 2004, includes a fourth coil, and when the second magnetic assembly 1002a drives the moving body 1002 to move along the second guide rail 1001b, the fourth coil cuts the magnetic induction line of the second magnetic assembly 1002a to generate a second induction current;
and a second detection assembly connected to the fifth magnetic assembly, for detecting a position of the moving body 1002 on the second guide rail 1001b based on a direction and intensity of the second induced current.
In the disclosed embodiment, currents of different directions and different intensities generated in the fourth coil can be used to characterize the position of the moving body 1002 on the second guide rail 1001 b.
It will be appreciated that the second coil of the fifth magnetic assembly generates a second induced current by cutting the magnetic induction wire. And the position of the moving body 1002 on the second guide rail 1001b can be detected through the intensity and direction of the second induced current, so as to further judge whether the driving assembly drives the moving body 1002 to move to the target position on the second guide rail 1001 b.
As shown in fig. 7, reference numeral 11 is a magnetic line direction of the second magnetic assembly 1002a, reference numeral 12 is a magnetic line direction generated by the first magnetic assembly 2001, and reference numeral 13 is a magnetic line direction generated by the fourth magnetic assembly 2004. In reference numeral 12, when a current is applied to the first magnetic assembly 2001 in opposite directions, a magnetic induction line in a direction indicated by a dotted line and a magnetic induction line in a direction indicated by a solid line are generated, and the magnetic induction line in the direction indicated by the dotted line and the magnetic induction line in the opposite direction indicated by the solid line are generated.
When the direction of the magnetic induction line generated by the first magnetic assembly 2001 is the direction shown by the dotted line, the moving body 1002 can be driven to rotate to the right side based on the interaction between the first magnetic assembly 2001 and the second magnetic assembly 1002 a; when the direction of the magnetic induction line generated by the first magnetic assembly 2001 is the direction shown by the solid line, the moving body 1002 can be driven to rotate to the left side based on the interaction between the first magnetic assembly 2001 and the second magnetic assembly 1002 a.
When the magnetic induction line direction generated by the fourth magnetic assembly 2004 is the magnetic induction line direction corresponding to the reference numeral 13, the moving body 1002 can be driven to rotate to the left side based on the interaction between the fourth magnetic assembly 2004 and the second magnetic assembly 1002 a.

In the embodiment of the present disclosure, the shape and size of the first opening of the housing are adapted to the shape and size of the optical signal emitting surface of the emitting module 10.
It should be noted that the shape of the second opening can be set according to the shape of the optical signal collecting surface of the image collecting module. For example, when the shape of the collection surface of the optical signal is a circle, the second opening may also be configured to be a circle; when the shape of the collection surface of the optical signal is an ellipse, the second opening may be provided as an ellipse.
Of course, the size of the second opening may also be set according to the size of the optical signal collection surface. For example, the size of the optical signal collection surface is set to be equal to the size of the second opening; alternatively, the size of the optical signal collection surface is set smaller than the size of the first opening.
It is understood that the moving body 1002 can move on the movable bracket 1001 so that the emitting range of the moving body 1002 emitting the light signal to the outside of the housing through the first opening can cover the entire target object 40. At this time, the image capturing assembly 20 can capture the laser light reflected by the target object 40 through the second opening, and can form a target image based on the reflected light signal, so that the capturing blind area of the image capturing module 20 can be reduced.
It should be noted that "first", "second", "third", "fourth", "fifth" and "sixth" in the embodiments of the present disclosure are merely for convenience of description and distinction, and have no other specific meaning.
