[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0034] In related technologies, motors often use suspended wires to control the movers, and open-loop system designs are often used in the zoom direction. The focusing speed is slow and the accuracy is low, and posture difference compensation is required. In addition, the mover structure process is relatively complex, with many welds. When dealing with usage scenarios with long-term vibration, reliability issues are also prone to occur.
[0035] In order to solve the above technical problems, according to an embodiment of the present disclosure, a motor, a camera module and an electronic device are provided, wherein the motor includes: a stator; a mover, and the mover includes a first mover and a second mover; the first mover is arranged inside the stator, and the first mover is slidingly connected to the stator in a first direction; the second mover is arranged inside the first mover, and the first mover and the second mover are rollingly connected in a second direction and a third direction; wherein the first direction, the second direction and the third direction are three different directions.
[0036] The present invention configures the first mover and the stator as a sliding connection and the first mover and the second mover as a rolling connection, thereby expanding the contact area between the stator and the mover while ensuring the driving speed and accuracy of the motor, reducing the damage to the motor when it is impacted, improving the reliability of the motor, reducing parts and components, and reducing the production cost of the motor.
[0037] It can be understood that the motor involved in the present disclosure can be applicable to any terminal listed below.
[0038] It is understandable that the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (User Equipment, UE), a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal, MT), etc., which is a device that provides voice and / or data connectivity to users.

[0039] Figure 1 is an exploded view of a motor according to an exemplary embodiment.
[0040] In some embodiments, Figure 1 As shown, the motor may include: a stator and a mover, and the mover may include a first mover 10 and a second mover 20 .
[0041] The stator can be the component in the motor with fixed position and shape, and the mover can be the component in the motor that moves.
[0042] The first mover 10 may be disposed inside the stator, and the first mover 10 may be slidably connected to the stator in a first direction, and the contact area between the first mover 10 and the stator may be expanded through the sliding connection.
[0043] The second mover 20 may be disposed inside the first mover 10 , and the first mover 10 and the second mover 20 may be rollingly connected in the second direction and the third direction, so that the first mover 10 and the second mover 20 may move relative to each other in the second direction and the third direction.
[0044] The first direction, the second direction and the third direction are three different directions.
[0045] The present invention configures the first mover 10 and the stator as a sliding connection, and configures the first mover 10 and the second mover 20 as a rolling connection. Under the condition of ensuring the driving speed and accuracy of the motor, the contact area between the stator and the mover is expanded, the damage to the motor when it is impacted is reduced, the reliability of the motor is improved, the number of parts is reduced, and the production cost of the motor is reduced.
[0046] In some embodiments, the first direction, the second direction, and the third direction may be three directions perpendicular to each other, so that omnidirectional movement is achieved through a combination of movements in the three directions.
[0047] Exemplarily, the first direction may be the optical axis direction of the camera module, and the camera module may realize an automatic zoom function by moving the lens in the first direction.
[0048] The second direction and the third direction may be directions perpendicular to the optical axis, and the second direction and the third direction may be perpendicular to each other. By moving the lens in the second direction and the third direction, the camera module can achieve an anti-shake function in any direction perpendicular to the optical axis.
[0049] Figure 2 It is a schematic structural diagram of a stator of a motor according to an exemplary embodiment. Figure 3 is a schematic structural diagram of a second carrier of a motor according to an exemplary embodiment.
[0050] In some embodiments, Figure 1-3 As shown, the motor may include: a sliding part 31 and a sliding rail 32 , the sliding part 31 may be arranged on the stator, the sliding rail 32 may be arranged on the mover, the sliding part 31 may be arranged in the sliding rail 32 , and the sliding part 31 may slide relative to the sliding rail 32 .
[0051] The slide rail 32 constrains the sliding direction of the sliding portion 31 to be the first direction, so through the sliding connection between the sliding portion 31 and the slide rail 32 , the stator and the first mover 10 can slide relative to each other in the first direction.
[0052] By providing a sliding portion 31 on the stator and a slide rail 32 on the mover, the first mover 10 and the stator can be configured as a sliding connection. While ensuring the motor driving speed and accuracy, the contact area between the stator and the mover is expanded, the damage to the motor when it is impacted is reduced, and the reliability of the motor is improved.
[0053] In some embodiments, Figure 1-3 As shown, the sliding portion 31 may include an arcuate surface, and the slide rail 32 may include a plane. The arcuate surface and the plane are in sliding contact, so that the sliding portion 31 and the slide rail 32 can form contact, avoiding point contact that easily leaves pits on the track when impacted, and avoiding surface contact that easily causes excessive sliding resistance, thereby improving the reliability of the motor and improving the smoothness of the motor's movement.
[0054] Exemplarily, the sliding portion 31 can be a semi-cylinder, the arcuate surface is the arcuate side surface of the semi-cylinder, the slide rail 32 can be a square groove, and the plane can be the bottom surface of the directional groove. When the sliding portion 31 slides in the slide rail 32, the arcuate surface is tangent to the plane, so that the sliding portion 31 forms a linear contact with the slide rail 32.
[0055] In some embodiments, Figure 3 As shown, the motor may include: a rolling member 41. The rolling member 41 may be disposed between the first mover 10 and the second mover 20, and the first mover 10 and the second mover 20 are connected in a rolling manner through the rolling member 41.
[0056] In some embodiments, the motor may include a positioning member 42 . The positioning member 42 may be disposed on the first mover 10 and the rolling member 41 may be disposed in the positioning member 42 . The positioning member 42 may fix the rolling member 41 at the position of the first mover 10 .
[0057] Exemplarily, the positioning member 42 can be a baffle structure surrounding the rolling member 41. By blocking the displacement of the rolling member 41 on the first mover 10, only the rolling member 41 and the first mover 10 are allowed to rotate, so that the position of the rolling member 41 on the first mover 10 is relatively fixed, which can ensure the stability and reliability of the rolling connection between the first mover 10 and the second mover 20.
[0058] In some embodiments, the motor may include: a recessed portion. The recessed portion may be provided on the surface where the second mover 20 contacts the rolling element 41. The rolling element 41 may contact the surface of the recessed portion and roll in the recessed portion, and the recessed portion may constrain the rolling element 41 to roll in the recessed portion, thereby constraining the relative motion range between the first mover 10 and the second mover 20.
[0059] Exemplarily, the recessed portion may be a square recessed structure, and the rolling element 41 may be blocked by the edge of the recessed portion when rolling, thereby being unable to continue to move relative to the second mover 20 .
[0060] In some embodiments, the motor may include: a driving component. The driving component may be a component that provides power, and the stator may drive the mover to move through the driving component.

[0075] The first magnetic member 61 may be a permanent magnetic member with a fixed magnetic pole direction. By setting the magnetic pole direction of the first magnetic member 61, the direction of the magnetic force applied by the first coil 51 to the first magnetic member 61 may be controlled, thereby allowing the first carrier 11 to move in the first direction.

[0078] The first magnetic member 61 and the second coil 52 , the first magnetic member 61 may be disposed on the first carrier 11 , and the second coil 52 may be disposed on the stator.
[0079] The second coil 52 can be energized to generate an induced magnetic field and exert a magnetic force on the second magnetic member 62 , so that the second magnetic member 62 and the first carrier 11 provided with the second magnetic member 62 move relative to the stator.
[0080] The second magnetic member 62 may be a permanent magnetic member with a fixed magnetic pole direction. By setting the magnetic pole direction of the second magnetic member 62, the direction of the magnetic force applied by the second coil 52 to the second magnetic member 62 may be controlled, thereby allowing the first carrier 11 to move in the first direction.
[0081] The third driving assembly may include a third magnetic member 63 that may be disposed on the second carrier 12 and a third coil 53 that may be disposed on the stator.
[0082] The first magnetic member 61 and the first coil 51 , the first magnetic member can be disposed on the first carrier 11 , and the first coil 51 can be disposed on the stator.
[0083] The first coil 51 can be energized to generate an induced magnetic field and exert a magnetic force on the third magnetic member 63 , so that the third magnetic member 63 and the first carrier 11 provided with the third magnetic member 63 move relative to the stator.
[0084] The third magnetic member 63 may be a permanent magnetic member with a fixed magnetic pole direction. By setting the magnetic pole direction of the third magnetic member 63, the direction of the magnetic force applied by the first coil 51 to the third magnetic member 63 may be controlled, thereby allowing the first carrier 11 to move in the first direction.
[0085] In some embodiments, Figure 1 and Figure 4 As shown, the driving assembly may include: a circuit board 70. The circuit board 70 may be disposed on the stator, and the first coil 51, the second coil 52 and the third coil 53 may be electrically connected to the circuit board 70.

[0087] In some embodiments, Figure 1 and Figure 2 As shown, the accommodation portion may include an opening, and during the production and installation process, the second mover 20 may be installed in the first mover 10 through the opening.
[0088] The motor may include a first bracket 80 , which may be disposed at the opening. At least a portion of the first bracket 80 may be fixedly connected to the second mover 20 , so that the first bracket 80 may limit the second mover 20 from falling off from the opening.
[0089] In some embodiments, the stator may include a second bracket 90 , which may be a frame structure of the stator and may provide a fixing and mounting position for other components of the motor. The first mover 10 and the second mover 20 may be disposed in the second bracket 90 .
[0090] In some embodiments, Figure 1 As shown, the stator may include a fourth magnetic member 64, which may be disposed on the outer side of a side of the stator on which the sliding portion 31 is disposed. Exemplarily, the second bracket 90 may include a first wall, the sliding portion 31 is disposed on the first wall, and the fourth magnetic member 64 may be disposed on the outer side of the first wall.

[0091] In some embodiments, the first wall can face the first magnetic member 61, thereby shortening the distance between the first magnetic member 61 and the fourth magnetic member 64, causing a magnetic attraction between the fourth magnetic member 64 and the first magnetic member 61, thereby causing the second mover 20 to be subjected to a force directed toward the sliding portion 31, thereby causing the sliding portion 31 and the slide rail 32 to be tightly combined, so that the mover and the stator can move along the first direction under the constraint of the slide rail 32.

[0101] The disclosed embodiment configures the first mover 10 and the stator as a sliding connection, and configures the first mover 10 and the second mover 20 as a rolling connection, thereby expanding the contact area between the stator and the mover while ensuring the motor driving speed and accuracy. In addition, the three-way closed-loop control system adopted in this scheme has a faster and more accurate autofocus speed and is not affected by posture differences. There is no lower limit spring plate in the structure, and the mover part has no welding process, so it has good reliability.
