[0034] Exemplarily, the second driving component 40 may include a coil and a magnetic member. The coil may be energized to generate an induced magnetic field and apply a magnetic force to the magnetic member, thereby causing the magnetic member and a mover provided with the magnetic member to move relative to the stator.

[0035] At least a portion of the second driving component 40 can be disposed on the second surface 12 of the first carrier 10. Exemplarily, the second driving component 40 may include a coil and a magnetic member. The magnetic member can be disposed on the second surface 12 of the first carrier 10, and the coil can be spaced apart from the magnetic member and opposite to the second surface 12 of the first carrier 10.

[0036] The present invention respectively arranges a first driving component 30 and a second driving component 40 on the two intersecting surfaces of the first carrier 10 of the motor, and drives the first carrier 10 through the combination of the first driving component 30 and the second driving component 40, so that the motor has a greater thrust, which can support the first carrier 10 to have a longer active stroke, realize the close-range focusing of the camera module, and enhance the zoom capability of the camera module.

[0037] In some embodiments, Figure 1 As shown, the motor may include: a second carrier 20 , and the second carrier 20 may be disposed opposite to the first surface 11 of the first carrier 10 .

[0038] The second carrier 20 may be a component that provides a fixing and mounting position for other components of the motor, and the first carrier 10 may be a component that is relatively fixed in the motor.

[0039] At least a portion of the first driving component 30 may be disposed on the second carrier 20. Exemplarily, the first driving component 30 may include a coil and a magnetic member, the magnetic member may be disposed on the first surface 11 of the first carrier 10, the coil may be disposed on the surface of the second carrier 20, and the coil may be spaced apart from the magnetic member and opposite to the first surface 11 of the first carrier 10.

[0045] The second magnetic member 32 can apply a magnetic force along the first direction to the first carrier 10 through the first magnetic member 31. For example, the second magnetic member 32 can apply an attractive force to the first carrier 10 through the first magnetic member 31, so that the first carrier 10 moves along the first direction and approaches the second magnetic member 32. The second magnetic member 32 can also apply a repulsive force to the first carrier 10 through the first magnetic member 31, so that the second carrier 20 moves along the first direction and moves away from the second magnetic member 32.

[0046] The present disclosure respectively arranges the first driving assembly 30 and the second driving assembly 40 on the two intersecting surfaces of the first carrier 10 of the motor, and arranges a part of the first driving assembly 30 on the second carrier 20 opposite to the first surface 11 of the first carrier 10, thereby ensuring the driving force of the first driving assembly 30. The first driving assembly 30 and the second driving assembly 40 drive the first carrier 10 in combination, so that the motor has a greater thrust, which can support the first carrier 10 to have a longer active stroke, realize the close-range focusing of the camera module, and improve the zoom capability of the camera module.

[0047] In some embodiments, the first magnetic member 31 may be a permanent magnet, and the second magnetic member 32 may be a coil.

[0052] The second magnetic member 32 may be a permanent magnetic member with a fixed magnetic pole direction. By setting the magnetic pole direction of the second magnetic member 32 , the direction of the magnetic force applied by the coil to the second magnetic member 32 may be controlled.

[0053] In some embodiments, the first driving component 30 may include a processor, and the processor may control the first driving component 30 . For example, the processor may control the magnitude and direction of the current in the coil, thereby changing the magnitude and direction of the magnetic force received by the first magnetic member 31 .

[0054] In some embodiments, the first driving component 30 may include a Hall element, which can determine the distance between the Hall element itself and the first magnetic component 31 or the second magnetic component 32 by detecting the magnetic induction intensity received by the Hall element, thereby detecting the position of the first carrier 10.

[0055] In some embodiments, Figure 1 As shown, the first magnetic member 31 and the second magnetic member 32 can be arranged with a gap. By arranging the first magnetic member 31 and the second magnetic member 32 with a gap, the first magnetic member 31 and the second magnetic member 32 can realize the magnetic effect on each other while reducing the collision impact between the first magnetic member 31 and the second magnetic member 32, reducing the collision between the first carrier 10 and other components, ensuring the displacement stability of the first carrier 10, and improving the reliability of the motor.

[0056] In some embodiments, the first magnetic member 31 may further include a third magnetic member, and the third magnetic member may be disposed on the second carrier 20, wherein the third magnetic member and the first magnetic member 31 mutually repel each other. Exemplarily, the first magnetic member 31 may be a permanent magnetic member, and the third magnetic member may be a permanent magnetic member. By making the same magnetic poles of the first magnetic member 31 and the third magnetic member face each other, the first magnetic member 31 and the third magnetic member mutually repel each other.

[0057] By making the first magnetic component 31 arranged on the first carrier 10 and the third magnetic component arranged on the second carrier 20 repel each other, a buffering effect can be provided for the first carrier 10 and the second carrier 20, thereby reducing the collision impact between the first carrier 10 and the second carrier 20, reducing the collision between the first carrier 10 and other components, ensuring the displacement stability of the first carrier 10, and improving the reliability of the motor.

[0058] In some embodiments, Figure 1 As shown, the motor may include a third carrier disposed opposite to the first surface 11 of the first carrier 10;

[0060] The fourth magnetic member 33 may be disposed on the first carrier 10 , and the fifth magnetic member 34 may be disposed on the third carrier, wherein the fifth magnetic member 34 may apply a magnetic force along the first direction to the first carrier 10 through the fourth magnetic member 33 .

[0061] The fourth magnetic member 33 can be disposed on the third carrier, and the fifth magnetic member 34 can be disposed on the second carrier 20. Exemplarily, the fourth magnetic member 33 can be disposed on the second surface 12 of the third carrier, and the fifth magnetic member 34 can be disposed on a surface of the second carrier 20 opposite to the third carrier.

[0062] The fourth magnetic member 33 and the fifth magnetic member 34 may interact with each other through magnetic force.

[0063] The fifth magnetic member 34 can apply a magnetic force along the first direction to the third carrier through the fourth magnetic member 33. For example, the fifth magnetic member 34 can apply an attractive force to the third carrier through the fourth magnetic member 33, so that the third carrier moves along the first direction and approaches the fifth magnetic member 34. The fifth magnetic member 34 can also apply a repulsive force to the third carrier through the fourth magnetic member 33, so that the second carrier 20 moves along the first direction and away from the fifth magnetic member 34.

[0064] The present disclosure respectively arranges the first driving assembly 30 and the second driving assembly 40 on the two intersecting surfaces of the third carrier of the motor, and arranges a part of the second driving assembly 40 on the second carrier 20 opposite to the second surface 12 of the third carrier, thereby ensuring the driving force of the second driving assembly 40. The third carrier is driven by the combination of the first driving assembly 30 and the second driving assembly 40, so that the motor has a greater thrust, which can support the third carrier to have a longer active stroke, realize the close-range focusing of the camera module, and improve the zoom capability of the camera module.
