Description

Technical Field

[0001] This invention relates to the technical field of optical element driving structures, and in particular to a motor and camera module. Background Technology

[0002] As a core component of portable electronic devices, the camera module presents a contradiction between its optical image stabilization (OIS) performance and module size: to achieve large-angle image stabilization, the size of the magnet and coil needs to be increased to provide sufficient driving force, which directly leads to an increase in the lateral size of the motor, conflicting with the trend of making devices thinner and lighter.

[0003] To balance the requirements of long-stroke anti-shake and miniaturization, some solutions introduce an intermediate frame to decompose the movement of the anti-shake carrier relative to the base into two vertical directions. However, since the drive components (magnet and coil) need to be positioned relative to each other along the optical axis to generate effective driving force, the gap between them usually needs to be controlled within 0.2mm. If the intermediate frame is placed between the drive components, although the lateral dimension can be reduced, the magnetic circuit gap will be significantly increased, resulting in a severe attenuation of the driving force. On the other hand, if the intermediate frame is placed entirely on the lateral side of the drive components, a certain safety gap must be reserved along the lateral movement direction to avoid mechanical interference between the drive components and the intermediate frame during movement, which will limit the space for reducing the lateral dimension of the motor. Summary of the Invention

[0004] Therefore, it is necessary to address the problem in existing technologies where the motion range of optical image stabilization and the lateral size of the motor cannot be simultaneously achieved. A solution should be provided that reduces the lateral size of the motor and camera module while ensuring interference-free large-stroke image stabilization.

[0005] This application first provides a motor for carrying an optical lens, including a base, a middle frame movably supported on the base along a first direction, a stabilizing carrier movably supported on the middle frame along a second direction, and a drive assembly, wherein the first direction and the second direction are perpendicular to each other and both are perpendicular to the optical axis direction of the optical lens.

[0011] In one embodiment, the intermediate frame includes a first frame connecting portion and a second frame connecting portion. The first frame connecting portion includes a first connecting arm, a first fixing end fixed to one end of the first connecting arm and fixed to the first frame support portion, and a second fixing end fixed to the other end of the first connecting arm and fixed to the second frame support portion. The second frame connecting portion includes a second connecting arm, a third fixing end fixed to one end of the second connecting arm and fixed to the second frame support portion, and a fourth fixing end fixed to the other end of the second connecting arm and fixed to the third frame support portion.

[0012] In one embodiment, the first fixed end and the second fixed end extend along the first direction, and the third fixed end and the fourth fixed end extend along the second direction.

[0013] In one embodiment, the first fixed end, the first connecting arm, and the second fixed end are integrally formed, and the first connecting arm is bent away from the base along the optical axis relative to the first fixed end and the second fixed end; the third fixed end, the second connecting arm, and the fourth fixed end are integrally formed, and the second connecting arm is bent closer to the base along the optical axis relative to the second fixed end and the fourth fixed end.

[0014] In one embodiment, the first fixed end, the first connecting arm, the second fixed end, the third fixed end, the second connecting arm, and the fourth fixed end are integrally formed.

[0015] In one embodiment, the dimension of the first connecting arm along the first direction is smaller than the dimension along the optical axis direction, and the dimension of the second connecting arm along the second direction is smaller than the dimension along the optical axis direction.

[0016] In one embodiment, the surfaces of the first connecting arm and the second connecting arm are provided with a plurality of stamped recesses.

[0017] In one embodiment, one of the first upper driving member and the first lower driving member is a first anti-shake magnet and the other is a first anti-shake coil; one of the second upper driving member and the second lower driving member is a second anti-shake magnet and the other is a second anti-shake coil; The first anti-shake magnet includes a first inner magnet portion, a first middle magnet portion, and a first outer magnet portion distributed along the first direction; the second anti-shake magnet includes a second inner magnet portion, a second middle magnet portion, and a second outer magnet portion distributed along the second direction. The first middle magnet portion has a dimension along the first direction that is larger than the first inner magnet portion and the first outer magnet portion, and / or the second middle magnet portion has a dimension along the second direction that is larger than the second inner magnet portion and the second outer magnet portion.

[0018] In one embodiment, the image stabilization carrier is provided with a focusing coil on the side opposite to the first upper drive member along the first direction, and the size of the first inner magnet portion along the first direction is smaller than that of the first outer magnet portion.

[0019] In one embodiment, the first anti-shake magnet is larger in size along the optical axis than the second anti-shake magnet, and the first anti-shake coil is smaller in size along the optical axis than the second anti-shake coil.

[0020] In one embodiment, the dimension from the top surface of the first stabilizing magnet to the bottom surface of the first stabilizing coil along the optical axis is equal to the dimension from the top surface of the second stabilizing magnet to the bottom surface of the second stabilizing coil along the optical axis.

[0021] This application also provides a camera module, including an optical lens, a photosensitive module, and the aforementioned motor; The optical lens is mounted on the image stabilization carrier and is used to receive and emit light along its own optical axis. The photosensitive module is disposed on the base and is used to receive light emitted from the optical lens for imaging.

[0022] The motor described above, through a specific layout in which the first connecting arm extends along the second direction to connect the first frame support and the second frame support, and the second connecting arm extends along the first direction to connect the second frame support and the third frame support, achieves bidirectional interference-free guidance when the middle frame moves relative to the base along the first direction and when the anti-shake carrier moves relative to the middle frame along the second direction. When the intermediate frame moves relative to the base in a first direction, the second connecting arm maintains a constant gap with the second lower drive member because it extends in the first direction, while the first connecting arm avoids interference by not overlapping with the first lower drive member and the base in the first direction; when the anti-shake carrier moves relative to the intermediate frame in a second direction, the first connecting arm maintains a constant gap with the first upper drive member because it extends in the second direction, while the second connecting arm avoids interference by not overlapping with the second upper drive member and the anti-shake carrier in the second direction. Therefore, while ensuring that the gap between the first drive component and the second drive component is set relative to each other along the optical axis to provide sufficient driving force, the lateral safety gap that needs to be reserved in the traditional design is effectively eliminated, and the lateral size of the motor is reduced.

[0031] Please combine Figures 1 to 4 As shown, this application first provides a motor for supporting an optical lens 1, including a base 10, a middle frame 20 movably supported on the base 10 along a first direction C1, a stabilizing carrier 30 movably supported on the middle frame 20 along a second direction C2, and a drive assembly 40. The first direction C1 and the second direction C2 are perpendicular to each other and both are perpendicular to the optical axis direction C3 of the optical lens 1. The drive assembly 40 includes a first drive assembly 41 and a second drive assembly 42. The first drive assembly 41 includes a first upper drive member 411 and a first lower drive member 412 disposed opposite to each other along the optical axis direction C3 to drive the middle frame 20 to move relative to the base 10 along the first direction C1. The second drive assembly 42 includes a second upper drive member 421 and a second lower drive member 421 disposed opposite to each other along the optical axis direction C3 to drive the stabilizing carrier 30 to move relative to the middle frame 20 along the second direction C2. The drive component 422, the first upper drive component 411 and the second upper drive component 421 are fixed to the anti-shake carrier 30, and the first lower drive component 412 and the second lower drive component 422 are fixed to the base 10; the intermediate frame 20 includes a first frame support 21, a second frame support 22, a third frame support 23, a first connecting arm 241 and a second connecting arm 251. The first frame support 21 and the second frame support 22 are located on both sides of the first drive component 41 along the second direction C2 and are connected by the first connecting arm 241. The second frame support 22 and the third frame support 23 are located on both sides of the second drive component 42 along the first direction C1 and are connected by the second connecting arm 251; the first connecting arm 241 and the first lower drive component 412 do not overlap in the first direction C1, and the second connecting arm 251 and the second upper drive component 421 do not overlap in the second direction C2.

[0032] In this application, based on the decomposition of optical image stabilization motion by the intermediate frame 20, and in conjunction with the specific spatial layout of the first connecting arm 241 and the second connecting arm 251, motion interference is effectively avoided and the lateral dimension of the motor is reduced while ensuring the large stroke image stabilization driving force.

[0033] Specifically, when the motor is working, the intermediate frame 20 moves relative to the base 10 along the first direction C1, and the anti-vibration carrier 30 moves relative to the intermediate frame 20 along the second direction C2. The states of the first connecting arm 241 and the second connecting arm 251 under the two movements are analyzed one by one: When the intermediate frame 20 and the anti-shake carrier 30 move together relative to the base 10 along the first direction C1, the second connecting arm 251 extends along the first direction C1 to connect the second frame support 22 and the third frame support 23. That is, the extension direction of the second connecting arm 251 (first direction C1) is parallel to the movement direction of the intermediate frame 20. Therefore, the distance between the second connecting arm 251 and the second lower drive member 422 remains constant during the movement, and no movement margin is required. At this time, the extension direction (second direction C2) of the first connecting arm 241 is perpendicular to the direction of movement. Therefore, the distance between the first connecting arm 241 and the first lower driving member 412 along the first direction C1 will change. Thus, by restricting the first connecting arm 241 from overlapping with the first lower driving member 412 along the first direction C1, it is made to be misaligned with the first lower driving member 412 during the movement along the first direction C1, so that there is no need to reserve a movement margin on the first direction C1 to avoid interference. When the anti-shake carrier 30 moves relative to the middle frame 20 along the second direction C2, the first connecting arm 241 extends along the second direction C2 to connect the first frame support 21 and the second frame support 22. That is, the extension direction of the first connecting arm 241 (second direction C2) is parallel to the movement direction of the anti-shake carrier 30. Therefore, the distance between the first connecting arm 241 and the first upper drive member 411 remains constant during the movement, and there is no need to reserve movement margin. At this time, the extension direction (first direction C1) of the second connecting arm 251 is perpendicular to the movement direction of the anti-shake carrier 30. Therefore, the distance between the second connecting arm 251 and the second upper driving member 421 along the second direction C2 will change. Thus, by restricting the second connecting arm 251 from overlapping with the second upper driving member 421 along the second direction C2, the second upper driving member 421 will not be misaligned with the second connecting arm 251 during the movement along the second direction C2, thereby eliminating the need to reserve movement margin in the second direction C2 to avoid interference.

[0034] Based on the above motion characteristics, it can be seen that the present application has a specific layout in which the first connecting arm 241 extends along the second direction C2 to connect the first frame support 21 and the second frame support 22, and the second connecting arm 251 extends along the first direction C1 to connect the second frame support 22 and the third frame support 23. This achieves bidirectional interference-free guidance when the middle frame 20 moves relative to the base 10 along the first direction C1 and when the anti-shake carrier 30 moves relative to the middle frame 20 along the second direction C2. When the intermediate frame 20 moves relative to the base 10 along the first direction C1, the second connecting arm 251 maintains a constant gap with the second lower drive member 422 because it extends along the first direction C1, and the first connecting arm 241 avoids interference by not overlapping with the first lower drive member 412 in the first direction C1; when the anti-shake carrier 30 moves relative to the intermediate frame 20 along the second direction C2, the first connecting arm 241 maintains a constant gap with the first upper drive member 411 because it extends along the second direction C2, and the second connecting arm 251 avoids interference by not overlapping with the second upper drive member 421 in the second direction C2; Therefore, while ensuring that the gap between the first drive assembly 41 and the second drive assembly 42 arranged relative to each other along the optical axis direction C3 is sufficient to provide sufficient driving force, the lateral safety gap that needs to be reserved in the traditional design is effectively eliminated, and the lateral size of the motor is reduced. It should be understood that the smaller the gap between the first drive assembly 41 and the second drive assembly 42 along the optical axis direction C3, the greater the driving force generated by both. Therefore, to ensure that the first drive assembly 41 and the second drive assembly 42 can provide sufficient driving force, no intermediate frame 20 is provided between the first drive assembly 41 and the second drive assembly 42. In some embodiments, the first connecting arm 241 overlaps with the first upper drive member 411 in the optical axis direction C3, and the second connecting arm 251 overlaps with the second lower drive member 422 in the optical axis direction C3. By utilizing the spatial layout in the optical axis direction C3, the lateral safety gap is eliminated.

[0035] Specifically, since the first connecting arm 241 overlaps with the first upper drive member 411 and the second connecting arm 251 overlaps with the second lower drive member 422 in the optical axis direction C3 (i.e., staggered arrangement), when the intermediate frame 20 and the anti-shake carrier 30 move relative to each other, even if the connecting arm and the drive member are completely overlapped on the horizontal projection plane, there will be no mechanical interference. Therefore, under the premise of ensuring no interference in the large stroke anti-shake movement, there is no need to reserve a safety gap or only a very small gap between the first connecting arm 241 and the first upper drive member 411 and between the second connecting arm 251 and the second lower drive member 422 in the first direction C1 and the second direction C2, thereby further reducing the lateral area occupied by the motor.

[0036] Please combine Figure 3 , Figure 5 as well as Figure 6 As shown, in some other embodiments, the first connecting arm 241 and the first upper driving member 411 do not overlap in the optical axis direction C3, and the second connecting arm 251 and the second lower driving member 422 do not overlap in the optical axis direction C3.

[0037] Based on the above motion characteristics, when the intermediate frame 20 moves relative to the base 10 along the first direction C1, since the second connecting arm 251 extends along the first direction C1, the distance between it and the fixed second lower drive member 422 in the second direction C2 remains constant. Therefore, only a very small constant gap needs to be set to avoid interference. Similarly, when the anti-shake carrier 30 moves relative to the intermediate frame 20 along the second direction C2, the first connecting arm 241 extends along the second direction C2, and the distance between it and the first upper drive member 411 in the first direction C1 remains constant. Again, only a very small constant gap needs to be set to avoid interference, and there is no need to reserve extra margin for change.

[0038] Furthermore, please combine Figure 3 , Figure 5 as well as Figure 6 As shown, in some embodiments, the first connecting arm 241 overlaps with the first upper driving member 411 in the first direction C1, and the second connecting arm 251 overlaps with the second lower driving member 422 in the second direction C2; that is, the first connecting arm 241 and the second connecting arm 251 do not need to occupy additional space in the optical axis direction C3. By reusing space in the horizontal direction, the effect of reducing the lateral size of the motor is achieved without increasing the size of the motor in the optical axis direction C3.

[0039] Furthermore, in some embodiments, along the optical axis direction C3, the first connecting arm 241 is higher than the second connecting arm 251.

[0040] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the first connecting arm 241 is located on the side of the first upper drive member 411 close to the optical axis of the optical lens 1 along the first direction C1, and the second connecting arm 251 is located on the side of the second lower drive member 422 away from the optical axis along the second direction C2; the spatial layout characteristics around the drive assembly 40 are fully utilized, and the lateral dimension of the motor is further compressed while ensuring the movement clearance of the optical lens 1.

[0041] It should be understood that the first connecting arm 241 and the first upper driving member 411 overlap in the first direction C1, and the space inside the first upper driving member 411 (near the optical axis) is occupied by the optical lens 1. Since the image stabilization carrier 30 and the intermediate frame 20 only have the degree of freedom of movement along the second direction C2, the size of the first upper driving member 411 and the optical lens 1 along the first direction C1 is fixed. Setting the first connecting arm 241 between the two can effectively utilize this fixed size space. As for the second connecting arm 251 and the second lower drive member 422, they overlap in the second direction C2. The space inside the second lower drive member 422 (near the optical axis) is occupied by the optical lens 1. Since the image stabilization carrier 30 will move relative to the base 10 along the second direction C2 under the action of the second upper drive member 421, that is, the optical lens 1 will move relative to the base 10 and the second lower drive member 422 along the second direction C2. Therefore, the inner side of the second lower drive member 422 (near the optical axis) needs to reserve a movement gap for the movement of the optical lens 1 along the second direction C2. Setting the second connecting arm 251 on the outer side can avoid occupying this necessary movement gap, thereby optimizing the lateral size of the motor while meeting the large stroke movement requirements of the image stabilization carrier 30 along the second direction C2.

[0042] Please combine Figure 3 as well as Figure 6 As shown, in some embodiments, the first connecting arm 241 overlaps at least partially with the first lower drive member 412 along the optical axis direction C3; and / or, the second connecting arm 251 overlaps at least partially with the second upper drive member 421 along the optical axis direction C3; thus achieving spatial reuse in the horizontal and vertical directions, and further reducing the lateral dimensions of the motor in the first direction C1 and / or the second direction C2 without increasing the total height of the motor in the optical axis direction C3.

[0043] Specifically, by having the first connecting arm 241 partially overlap with the first lower drive member 412 in the optical axis direction C3, and the second connecting arm 251 partially overlap with the second upper drive member 421 in the optical axis direction C3, a staggered arrangement can be formed, allowing the first connecting arm 241 to make full use of the vertical space above the first lower drive member 412, and the second connecting arm 251 to make full use of the vertical space below the second upper drive member 421, thereby allowing the size of the motor in the first direction C1 and / or the second direction C2 to be further reduced.

[0044] Please combine Figure 2 , Figure 4 as well as Figure 17 As shown, in some embodiments, the motor satisfies: L1 > D1 + ΔC2, and L2 > D2 + ΔC1; where L1 is the dimension of the first connecting arm 241 along the second direction C2, D1 is the dimension of the first upper drive member 411 along the second direction C2, ΔC2 is the rated stroke of the anti-shake carrier 30 along the second direction C2 relative to the intermediate frame 20 (i.e., the designed stroke of the motor in this direction), L2 is the dimension of the second connecting arm 251 along the first direction C1, D2 is the dimension of the second lower drive member 422 along the first direction C1, and ΔC1 is the rated stroke of the intermediate frame 20 along the first direction C1 relative to the base 10.

[0045] This configuration, by designing that the dimensional difference between the first connecting arm 241 and the first upper drive member 411 along the second direction C2 is greater than the rated stroke of the motor along the second direction C2, and the dimensional difference between the second connecting arm 251 and the second lower drive member 422 along the first direction C1 is greater than the rated stroke of the motor along the first direction C1, allows for clearances to accommodate possible assembly tolerances, component tolerances, and potential impact risks during non-operational states. It effectively avoids the possibility of mechanical interference between the connection structures at both ends of the first connecting arm 241 and the second connecting arm 251 and the first lower drive member 412 and the second upper drive member 421 during anti-shake motion, ensuring the reliability and stability of large-stroke anti-shake motion.

[0046] Specifically, when the anti-shake carrier 30 moves relative to the intermediate frame 20 along the second direction C2, the first upper drive member 411 fixed to the anti-shake carrier 30 generates a displacement of up to ΔC2 along the second direction C2. Since the dimension of the first upper drive member 411 along the second direction C2 is D1, by setting L1 > D1 + ΔC2, it is ensured that the extension length of the first connecting arm 241 in the second direction C2 can always cover the width of the first upper drive member 411 and its corresponding anti-shake movement margin. Thus, no matter what position the anti-shake carrier 30 moves to, it can effectively prevent interference between the first frame support 21 or the second frame support 22 connected by the first connecting arm 241 and the first upper drive member 411. Similarly, by setting L2>D2+△C1, no matter what position the intermediate frame 20 moves to along the first direction C1, it can effectively prevent the second frame support 22 or the third frame support 23 connected by the second connecting arm 251 from interfering with the second lower drive member 422 fixed to the base 10.

[0047] Please combine Figure 2 as well as Figure 7 As shown, in some embodiments, the intermediate frame 20 includes a first frame connecting portion 24 and a second frame connecting portion 25. The first frame connecting portion 24 includes a first connecting arm 241, a first fixing end 242 fixed to one end of the first connecting arm 241 and fixed to the first frame support portion 21, and a second fixing end 243 fixed to the other end of the first connecting arm 241 and fixed to the second frame support portion 22. The second frame connecting portion 25 includes a second connecting arm 251, a third fixing end 252 fixed to one end of the second connecting arm 251 and fixed to the second frame support portion 22, and a fourth fixing end 253 fixed to the other end of the second connecting arm 251 and fixed to the third frame support portion 23.

[0048] Three frame supports are connected by two frame connecting parts to form an L-shaped intermediate frame 20. The first connecting arm 241 and the second connecting arm 251 are rigidly connected to the three frame supports through their respective fixed ends, which enhances the overall structural strength of the intermediate frame 20.

[0049] Furthermore, in some embodiments, the first fixing end 242 is fixed to the first frame support 21 in an embedded manner; the second fixing end 243 and the third fixing end 252 are fixed to the second frame support 22 in an embedded manner; and the fourth fixing end 253 is fixed to the third frame support 23 in an embedded manner.

[0050] Please combine Figure 2 as well as Figure 7 As shown, in some embodiments, the first fixed end 242 and the second fixed end 243 extend along the first direction C1, and the third fixed end 252 and the fourth fixed end 253 extend along the second direction C2.

[0051] Since the first fixed end 242 and the second fixed end 243 extend along the first direction C1, the gap adjustment between the first connecting arm 241 and the first upper driving member 411 does not depend on the size and position of the first frame support 21 and the second frame support 22 along the first direction C1, thereby allowing the lateral dimensions of the first frame support 21 and the second frame support 22 to be reduced. Similarly, the third fixed end 252 and the fourth fixed end 253 extend along the second direction C2, so that the gap adjustment between the second connecting arm 251 and the second lower driving member 422 does not depend on the size and position of the second frame support 22 and the third frame support 23 along the second direction C2, thereby providing design freedom for reducing the lateral dimensions of the second frame support 22 and the third frame support 23, and ultimately achieving further compression of the motor's lateral dimensions while ensuring the motion clearance.

[0052] Furthermore, in some embodiments, the projections of the first fixed end 242, the second fixed end 243, the third fixed end 252, and the fourth fixed end 253 along the optical axis direction C3 are all L-shaped, and each is divided into two segments from the inflection point of the L-shape; wherein, one segment of the first fixed end 242 extends along the second direction C2 and is fixed to the first frame support 21, and the other segment extends along the first direction C1; one segment of the second fixed end 243 extends along the second direction C2 and is fixed to the second frame support 22, and the other segment extends along the first direction C1; one segment of the third fixed end 252 extends along the first direction C1 and is fixed to the second frame support 22, and the other segment extends along the second direction C2; one segment of the fourth fixed end 253 extends along the first direction C1 and is fixed to the third frame support 23, and the other segment extends along the second direction C2.

[0053] Please combine Figure 2as well as Figure 7 As shown, in some embodiments, the first fixed end 242, the first connecting arm 241 and the second fixed end 243 are integrally formed, and the first connecting arm 241 is bent away from the base 10 along the optical axis direction C3 relative to the first fixed end 242 and the second fixed end 243, so that the first connecting arm 241 maintains a sufficient cross-sectional area to ensure structural strength, while converting its size requirement in the first direction C1 into a height requirement in the optical axis direction C3, thereby reducing the space occupied by the first connecting arm 241 in the first direction C1; The third fixed end 252, the second connecting arm 251 and the fourth fixed end 253 are integrally formed, and the second connecting arm 251 is bent towards the base 10 along the optical axis direction C3 relative to the third fixed end 252 and the fourth fixed end 253. Similarly, the size requirement of the second connecting arm 251 in the second direction C2 is transformed into the height requirement in the optical axis direction C3, thereby reducing the space occupied by the second connecting arm 251 in the second direction C2.

[0054] Accordingly, the first connecting arm 241 is perpendicular to the first fixed end 242 and the second fixed end 243, and the second connecting arm 251 is perpendicular to the third fixed end 252 and the fourth fixed end 253.

[0055] Furthermore, please combine Figure 2 as well as Figure 7 As shown, in some embodiments, the first fixed end 242, the first connecting arm 241, the second fixed end 243, the third fixed end 252, the second connecting arm 251, and the fourth fixed end 253 are integrally formed. That is, the second fixed end 243 and the third fixed end 252 are connected and fixed to each other so that the first frame connecting part 24 and the second frame connecting part 25 are integrally connected. Thus, the frame connecting part of the entire intermediate frame 20 is formed by bending a metal part, eliminating the connection gap and loosening risk between each fixed end and the connecting arm, and improving the overall structural rigidity and movement stability of the intermediate frame 20. Meanwhile, the one-piece molding manufacturing process simplifies the assembly process of the intermediate frame 20, reduces the number of parts and the accumulation of assembly errors, and ensures the relative positional accuracy between each connecting arm and the fixed end when the intermediate frame 20 moves relative to the base 10 along the first direction C1 and the anti-shake carrier 30 moves relative to the intermediate frame 20 along the second direction C2. This ensures the stability of the constant gap between the first connecting arm 241 and the first upper drive member 411, and between the second connecting arm 251 and the second lower drive member 422, and further optimizes the anti-shake motion accuracy of the motor.

[0056] Please combine Figure 2 as well as Figure 7As shown, in some embodiments, the dimension of the first connecting arm 241 along the first direction C1 is smaller than the dimension along the optical axis direction C3, and the dimension of the second connecting arm 251 along the second direction C2 is smaller than the dimension along the optical axis direction C3.

[0057] By optimizing the width-to-thickness ratio of the cross-section of the first connecting arm 241 and the second connecting arm 251, the material is concentrated in the optical axis direction C3 to increase the thickness. At the same time, the lateral dimensions of the first connecting arm 241 in the first direction C1 and the second connecting arm 251 in the second direction C2 are reduced, thereby further reducing the lateral dimensions of the motor while ensuring the structural strength of the intermediate frame 20.

[0058] It is easy to understand that since the bending resistance of the connecting arm mainly depends on its cross-sectional area, the above design ensures that the cross-sectional area of ​​the connecting arm remains unchanged by increasing the thickness and reducing the lateral dimensions. This allows the connecting arm to be arranged in a flat shape while maintaining the necessary structural strength, minimizing the space it occupies in the horizontal direction and achieving a balance between strength and miniaturization.

[0059] Furthermore, in some embodiments, the dimensions of the first fixed end 242, the second fixed end 243, the third fixed end 252, and the fourth fixed end 253 along the optical axis direction C3 are smaller than their dimensions along the transverse direction; that is, all four fixed ends are flat and extend laterally.

[0060] Accordingly, the first connecting arm 241 is perpendicular to the first fixed end 242 and the second fixed end 243, and the second connecting arm 251 is perpendicular to the third fixed end 252 and the fourth fixed end 253.

[0061] Furthermore, in some embodiments, the surfaces of the first connecting arm 241 and the second connecting arm 251 are provided with a plurality of stamped recesses.

[0062] By forming multiple pits (prickling process) on the surface, stress relief points are introduced on the material surface, which can disperse and absorb the bending stress generated by the connecting arm when it is under force, and offset the problem of reduced structural rigidity caused by the optimization of the width-to-thickness ratio. This reduces the bending deformation of the first connecting arm 241 and the second connecting arm 251, and ensures the structural stability and guiding accuracy when the intermediate frame 20 moves relative to the base 10 in the first direction C1 and the anti-shake carrier 30 moves relative to the intermediate frame 20 in the second direction C2.

[0063] Furthermore, in some embodiments, the pit depth is 0.01mm-0.03mm. Preferably, the pit depth is 0.02mm.

[0064] Please combine Figure 1 , Figure 2 , Figure 4 as well as Figure 8As shown, in some embodiments, the motor also includes an upper cover 50 fixed to the base 10. The base 10 and the upper cover 50 together form a cavity for accommodating the intermediate frame 20, the anti-shake carrier 30 and other internal components, providing structural support and protection for the various components of the motor.

[0065] Specifically, the base 10 includes a first base side 11 and a second base side 12 arranged adjacent to each other, and the image stabilization carrier 30 includes a first image stabilization carrier side 31 and a second image stabilization carrier side 32 arranged adjacent to each other. The first base side 11 and the first image stabilization carrier side 31 are arranged opposite to each other along the optical axis direction C3, and the second base side 12 and the second image stabilization carrier side 32 are arranged opposite to each other along the optical axis direction C3. The first lower drive member 412 is fixed to the side of the first base 11, and the second lower drive member 422 is fixed to the side of the second base 12, so that the first lower drive member 412 and the second lower drive member 422 are arranged adjacent to each other on the adjacent sides of the base 10. The first upper drive member 411 is fixed to the side 31 of the first anti-shake carrier, and the second upper drive member 421 is fixed to the side 32 of the second anti-shake carrier, so that the first upper drive member 411 and the second upper drive member 421 are arranged adjacent to each other on the adjacent sides of the anti-shake carrier 30.

[0066] Furthermore, please combine Figure 2 as well as Figure 9 As shown, in some embodiments, a plurality of anti-shake damping elements 33 are also fixed to the periphery of the anti-shake carrier 30. The anti-shake damping elements 33 are made of elastic materials, such as rubber, silicone or thermoplastic elastomers, and are used to buffer the impact when the anti-shake carrier 30 collides with the top cover 50 and reduce the noise generated.

[0067] Specifically, the anti-shake and shock-absorbing component 33 can be fixed to the anti-shake carrier 30 by means of injection molding, bonding or snap-fitting.

[0068] In one specific embodiment, two anti-shake damping components 33 are provided on each side of the image stabilization carrier 30, and the anti-shake damping components 33 are integrally molded onto the image stabilization carrier 30 by injection molding to ensure the reliability and consistency of the connection. It should be understood that since the intermediate frame 20 moves relative to the base 10 along the first direction C1, and the image stabilization carrier 30 moves relative to the intermediate frame 20 along the second direction C2, the image stabilization carrier 30 can ultimately perform two-dimensional movement relative to the base 10 in the horizontal plane. Therefore, the anti-shake damping components 33 are distributed on each side of the image stabilization carrier 30 to ensure that the impact with the top cover 50 can be effectively buffered under any movement posture, protecting the optical lens 1 and its internal precision structure.

[0069] Please combine Figure 2 , Figure 7 as well as Figure 10As shown, in some embodiments, the motor further includes a plurality of first support members 61 disposed between the intermediate frame 20 and the anti-shake carrier 30, and a plurality of second support members 62 disposed between the anti-shake carrier 30 and the base 10. The first support members 61 are used to maintain a gap between the anti-shake carrier 30 and the intermediate frame 20 and reduce the frictional resistance of the anti-shake carrier 30 relative to the intermediate frame 20; the second support members 62 are used to maintain a gap between the intermediate frame 20 and the base 10 and reduce the frictional resistance of the intermediate frame 20 relative to the base 10.

[0070] The first support member 61 and the second support member 62 can be implemented as balls, rollers, sliders or other rolling or sliding elements suitable for reducing frictional resistance, and their number can be set to an odd number or a plural number according to the size and load requirements of the motor.

[0071] In one specific embodiment, both the first support 61 and the second support 62 are implemented as balls to achieve smooth motion guidance by utilizing the low coefficient of friction of the balls.

[0072] Please combine Figure 2 , Figure 7 as well as Figures 10-12 As shown, in some embodiments, in order to constrain the range of motion of the first support member 61 and the second support member 62, the motor further includes a frame lower receiving groove 26 and a base upper receiving groove 13 arranged opposite to each other, and a carrier lower receiving groove 34 and a frame upper receiving groove 27 arranged opposite to each other. The frame lower receiving groove 26 is formed on the side of the intermediate frame 20 facing the base 10, and the base upper receiving groove 13 is formed on the side of the base 10 facing the intermediate frame 20. The frame lower receiving groove 26 and the base upper receiving groove 13 correspond one-to-one and together form a receiving cavity for accommodating the second support member 62. The carrier lower receiving groove 34 is formed on the side of the anti-shake carrier 30 facing the intermediate frame 20, and the frame upper receiving groove 27 is formed on the side of the intermediate frame 20 facing the anti-shake carrier 30. The carrier lower receiving groove 34 and the frame upper receiving groove 27 correspond one-to-one and together form a receiving cavity for accommodating the first support member 61.

[0073] Specifically, please combine Figure 10 as well as Figure 11 As shown, in some embodiments, the base 10 has three upper base receiving grooves 13 on the side facing the middle frame 20, and the middle frame 20 has three lower frame receiving grooves 26 on the side facing the base 10, with the lower frame receiving grooves 26 corresponding to the upper base receiving grooves 13 respectively.

[0074] More specifically, the receiving grooves 13 on the base are located at the three corners of the base 10, and the receiving grooves 26 under the three frames are located at the three corners of the middle frame 20, so that the distance between each pair of the second support members 62 housed therein can be set to be larger, thereby improving the stability of the movement of the middle frame 20 relative to the base 10.

[0075] Furthermore, in some embodiments, at least one pair of oppositely arranged lower frame receiving grooves 26 and upper base receiving grooves 13 extend along a first direction C1, so that the second support member 62 housed therein has space to move relative to the lower frame receiving grooves 26 and / or the upper base receiving grooves 13 along the first direction C1, thereby reducing the jamming problem when the intermediate frame 20 moves relative to the base 10 and improving the smoothness of movement.

[0076] In one specific embodiment, the three pairs of opposing frame-lower receiving grooves 26 and base-higher receiving grooves 13 all extend along the first direction C1. In other words, the length direction of the three pairs of opposing frame-lower receiving grooves 26 and base-higher receiving grooves 13 is parallel to the first direction C1.

[0077] Furthermore, in order to limit the direction of movement of the intermediate frame 20 relative to the base 10 to the first direction C1, the groove walls of at least one pair of oppositely arranged frame lower receiving groove 26 and base upper receiving groove 13 are configured to restrict the displacement of the second support member 62 contained therein in the direction perpendicular to the first direction C1, thereby guiding the intermediate frame 20 to move relative to the base 10 only along the first direction C1.

[0078] In one specific embodiment, the walls of the two pairs of opposing frame-mounted receiving grooves 26 and base-mounted receiving grooves 13 are configured to restrict the displacement of the second support member 62 contained therein in a direction perpendicular to the first direction C1.

[0079] It should be understood that setting it into two pairs allows the movement of the intermediate frame 20 relative to the base 10 to be better restricted in the first direction C1. On the other hand, it allows the second support member 62 to be accommodated in the lower frame receiving groove 26 and the upper base receiving groove 13, which are arranged opposite to each component, even when each component has tolerances. This reduces the requirements for the tolerances of each component.

[0080] Preferably, the two pairs of oppositely arranged frame lower receiving grooves 26 and base upper receiving grooves 13 are spaced apart along the first direction C1.

[0081] Furthermore, in some embodiments, in order to configure the walls of the oppositely arranged lower frame receiving groove 26 and upper base receiving groove 13 to restrict the displacement of the second support member 62 housed therein in the direction perpendicular to the first direction C1, the walls of the lower frame receiving groove 26 and upper base receiving groove 13 are both set with a V-shaped cross section or an approximately V-shaped cross section, so that the lower frame receiving groove 26 and upper base receiving groove 13 each have at least two sides in contact with the second support member 62, thereby achieving a guiding function.

[0082] Similarly, please combine Figure 7 as well as Figure 12 As shown, in some embodiments, the stabilizing carrier 30 has three carrier lower receiving slots 34 on the side facing the middle frame 20, and the middle frame 20 has three frame upper receiving slots 27 on the side facing the stabilizing carrier 30, with the frame upper receiving slots 27 corresponding to the carrier lower receiving slots 34 respectively.

[0083] Specifically, the three carrier lower receiving slots 34 and the three frame upper receiving slots 27 are located at the corners of the anti-shake carrier 30 and the intermediate frame 20, respectively, so that the distance between each pair of the first support members 61 housed therein can be set to be larger, thereby improving the stability of the movement of the anti-shake carrier 30 relative to the intermediate frame 20.

[0084] Furthermore, in some embodiments, at least one pair of oppositely arranged carrier lower receiving groove 34 and frame upper receiving groove 27 extend along the second direction C2, so that the first support member 61 housed therein has space to move relative to the carrier lower receiving groove 34 and / or frame upper receiving groove 27 along the second direction C2, thereby reducing the jamming problem when the anti-shake carrier 30 moves relative to the intermediate frame 20 and improving the smoothness of movement.

[0085] In one specific embodiment, the three pairs of opposing carrier lower receiving grooves 34 and frame upper receiving grooves 27 all extend along the second direction C2. In other words, the length direction of the three pairs of opposing carrier lower receiving grooves 34 and frame upper receiving grooves 27 is parallel to the second direction C2.

[0086] Furthermore, in order to limit the direction of movement of the stabilizing carrier 30 relative to the intermediate frame 20 to the second direction C2, the walls of at least one pair of oppositely arranged carrier lower receiving groove 34 and frame upper receiving groove 27 are configured to restrict the displacement of the first support member 61 contained therein in the direction perpendicular to the second direction C2, thereby guiding the stabilizing carrier 30 to move relative to the intermediate frame 20 only along the second direction C2.

[0087] In one specific embodiment, the walls of the two pairs of opposing carrier lower receiving grooves 34 and frame upper receiving grooves 27 are configured to restrict the displacement of the first support 61 contained therein in a direction perpendicular to the second direction C2.

[0088] Preferably, the two pairs of oppositely arranged carrier lower receiving grooves 34 and frame upper receiving grooves 27 are spaced apart along the second direction C2.

[0089] Furthermore, in some embodiments, in order to configure the walls of the oppositely arranged carrier lower receiving groove 34 and frame upper receiving groove 27 to restrict the displacement of the first support member 61 contained therein in the direction perpendicular to the second direction C2, the walls of the carrier lower receiving groove 34 and frame upper receiving groove 27 are both set with a V-shaped cross section or an approximately V-shaped cross section, so that the carrier lower receiving groove 34 and frame upper receiving groove 27 each have at least two sides in contact with the first support member 61, thereby achieving a guiding function.

[0090] Please combine Figure 5 as well as Figure 6 As shown, in some embodiments, one of the first upper drive member 411 and the first lower drive member 412 is a stabilizing magnet and the other is a stabilizing coil; one of the second upper drive member 421 and the second lower drive member 422 is a stabilizing magnet and the other is a stabilizing coil; the stabilizing magnet and the stabilizing coil are arranged opposite each other along the optical axis direction C3. When the stabilizing coil is energized, a Lorentz force is generated under the action of the magnetic field provided by the stabilizing magnet, thereby driving the stabilizing carrier 30 to move relative to the base 10 in the corresponding direction.

[0091] Please combine Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, in one specific embodiment, the first upper drive member 411 is a first anti-shake magnet 41a, and the first lower drive member 412 is a first anti-shake coil 41b; the second upper drive member 421 is a second anti-shake magnet 42a, and the second lower drive member 422 is a second anti-shake coil 42b. The first anti-shake magnet 41a is fixed to the side 31 of the first anti-shake carrier, the second anti-shake magnet 42a is fixed to the side 32 of the second anti-shake carrier, the first anti-shake coil 41b is fixed to the side 11 of the first base, and the second anti-shake coil 42b is fixed to the side 12 of the second base.

[0092] It is worth mentioning that, in this application, in order to improve the driving force of the long-stroke motor, the first anti-vibration magnet 41a and / or the second anti-vibration magnet 42a may adopt a Halbach magnet array structure. The Halbach magnet array, through a specific magnetic pole arrangement, can enhance the magnetic field strength near the coil side while weakening the magnetic field strength away from the coil side, thereby providing a greater effective driving force with the same magnet volume.

[0093] Please combine Figure 5 as well as Figure 6As shown, in some embodiments, each anti-shake magnet includes at least three magnet parts: a middle anti-shake magnet part located in the middle, and an outer anti-shake magnet part and an inner anti-shake magnet part located on both sides, respectively.

[0094] Accordingly, the first anti-shake magnet 41a includes a first inner magnet portion 41a1, a first middle magnet portion 41a2, and a first outer magnet portion 41a3 distributed along the first direction C1, and the second anti-shake magnet 42a includes a second inner magnet portion 42a1, a second middle magnet portion 42a2, and a second outer magnet portion 42a3 distributed along the second direction C2.

[0095] Specifically, the magnetic poles of the middle anti-shake magnet are horizontally oriented (i.e., perpendicular to the optical axis C3 and parallel to the corresponding direction of motion), while the magnetic poles of the outer and inner anti-shake magnets are vertically oriented (i.e., parallel to the optical axis C3) and opposite in direction. This magnetic pole arrangement enhances the magnetic field on the side closer to the anti-shake coil, thereby increasing the driving force.

[0096] In some embodiments, the size of the middle anti-shake magnet portion along its own relative motion direction is greater than that of the outer anti-shake magnet portions and the inner anti-shake magnet portions located on both sides; that is, the size of the first middle magnet portion 41a2 along the first direction C1 is greater than that of the first inner magnet portion 41a1 and the first outer magnet portion 41a3, and / or, the size of the second middle magnet portion 42a2 along the second direction C2 is greater than that of the second inner magnet portion 42a1 and the second outer magnet portion 42a3.

[0097] The larger size of the anti-shake magnet in the middle section can effectively reduce the decrease in driving force at the edge of the stroke, thereby optimizing the anti-shake effect of the large stroke motor. When the middle frame 20 moves to the edge of the stroke relative to the base 10 along the first direction C1, the first anti-shake coil 41b can still maintain sufficient magnetic field coupling with the first anti-shake magnet 41a, thereby maintaining a stable driving force output.

[0098] In some embodiments, the outer anti-shake magnet portion and the inner anti-shake magnet portion located on both sides have different dimensions along their relative motion direction; that is, the first inner magnet portion 41a1 and the first outer magnet portion 41a3 have different dimensions along the first direction C1, and / or the second inner magnet portion 42a1 and the second outer magnet portion 42a3 have different dimensions along the second direction C2.

[0099] By reducing the size of one of the magnet parts in the direction of relative motion, the lateral size of the motor can be reduced, thereby achieving the goal of motor miniaturization.

[0100] Please combine Figure 3 , Figure 6 as well as Figure 9As shown, in some embodiments, the image stabilization carrier 30 is further provided with a first focusing drive (focusing magnet 110 or focusing coil 120). The outer portion of the image stabilization magnet on the opposite / same side of the first focusing drive has a smaller dimension along its own relative movement direction than the inner portion. In this way, the increased lateral dimension of the motor due to the provision of the first focusing drive can be offset to some extent by the improvement of the image stabilization magnet.

[0101] Accordingly, since the lateral dimension of the outer anti-shake magnet portion is smaller than that of the inner anti-shake magnet portion, in order to improve the symmetry of the driving force curve between the anti-shake magnet and the corresponding anti-shake coil, in some embodiments, the anti-shake magnet is offset inward (to one side of the optical axis) in the motor's natural state. That is, in the motor's natural state, the center of the middle anti-shake magnet portion is closer to the optical axis than the center of the anti-shake coil. Here, the natural state refers to the state when the motor is not powered on.

[0102] In one specific embodiment, a focusing coil 120 is provided on the side of the image stabilization carrier 30 opposite to the first upper drive member 411 along the first direction C1, and the first inner magnet portion 41a1 of the first image stabilization magnet 41a is smaller in size than the first outer magnet portion 41a3 along the first direction C1; furthermore, the first image stabilization magnet 41a is offset inward (to the optical axis side) in the natural state of the motor.

[0103] Please combine Figure 3 , Figure 5 as well as Figure 6 As shown, in some embodiments, the size of the first stabilizing magnet 41a along the optical axis direction C3 is larger than that of the second stabilizing magnet 42a, and the size of the first stabilizing coil 41b along the optical axis direction C3 is smaller than that of the second stabilizing coil 42b; the size of the top surface of the first stabilizing magnet 41a to the bottom surface of the first stabilizing coil 41b along the optical axis direction C3 is equal to the size of the top surface of the second stabilizing magnet 42a to the bottom surface of the second stabilizing coil 42b along the optical axis direction C3.

[0104] Because the lateral dimensions of the first anti-shake magnet 41a and the second anti-shake magnet 42a are reduced differently, or only the lateral dimension of the first anti-shake magnet 41a is reduced, the first driving force generated by the first anti-shake magnet 41a and the first anti-shake coil 41b is different from the second driving force generated by the second anti-shake magnet 42a and the second anti-shake coil 42b. In this regard, by adjusting the height dimensions (along the optical axis direction C3) of the first anti-shake magnet 41a, the second anti-shake magnet 42a, the first anti-shake coil 41b, and the second anti-shake coil 42b, the driving forces on both sides can be balanced.

[0105] Specifically, the height of the first anti-shake magnet 41a is increased to increase its volume, and correspondingly, the height of the first anti-shake coil 41b is reduced to avoid an increase in the overall height.

[0106] In some embodiments, the anti-shake carrier 30 is further fixed with an anti-shake magnet conductor; the anti-shake magnet conductor is made of a magnetically conductive material, such as soft iron, silicon steel or other high magnetic permeability alloy.

[0107] The anti-shake magnet is located on the side of the anti-shake magnet away from the anti-shake coil. On the one hand, it can optimize the magnetic field distribution provided by the anti-shake magnet to the anti-shake coil and enhance the effective magnetic flux. On the other hand, it can also enhance the structural strength of the anti-shake carrier 30.

[0108] Specifically, the first anti-shake magnet 41a and the second anti-shake magnet 42a are respectively fixed to the anti-shake carrier 30 through corresponding anti-shake magnet conductive parts; the anti-shake magnet conductive parts can be fixed to the anti-shake carrier 30 by means of bonding, snapping or embedding.

[0109] It is worth mentioning that the setting of the anti-shake magnet is adapted to the motion characteristics of the intermediate frame 20. Its size and position are optimized to avoid interference with the first frame connection part 24 or the second frame connection part 25 of the intermediate frame 20 during the movement of the intermediate frame 20 and the anti-shake carrier 30.

[0110] Please refer to Figure 13 As shown, in some embodiments, the motor further includes a conductive component 70 for supplying power to the first anti-shake coil 41b and the second anti-shake coil 42b; the conductive component 70 includes a base conductive portion 71, which is fixed to the base 10, and the first anti-shake coil 41b and the second anti-shake coil 42b are electrically connected to the base conductive portion 71 to obtain the electrical energy required for driving.

[0111] In some embodiments, the base conductive portion 71 is embedded within the base 10 to reduce the overall size of the motor. For example, the base conductive portion 71 includes a plurality of conductive inserts and is embedded into the base 10 by insert injection molding, such that a portion of the conductive insert protrudes from the surface of the base 10 to be electrically connected to the anti-vibration coil, and another portion extends to the edge of the base 10 to be connected to an external circuit.

[0112] In some embodiments, the anti-shake coil is disposed on the anti-shake carrier 30, and the base conductive part 71 is connected to the anti-shake coil via a flexible circuit board (FPC) or an elastic conductive element, so as to allow the intermediate frame 20 and the anti-shake carrier 30 to perform anti-shake movement while maintaining electrical connection.

[0113] Please combine Figure 3 as well as Figure 13 As shown, in some embodiments, the motor further includes a magnetic attraction assembly 80, which includes a first anti-shake magnetic attraction element 81 and a second anti-shake magnetic attraction element 82. The first anti-shake magnetic attraction element 81 and the second anti-shake magnetic attraction element 82 are implemented as elements suitable for magnetic attraction with a magnet, such as a magnet, a soft magnetic material block, or an electromagnet.

[0114] The first anti-shake magnetic component 81 is magnetically attracted to the first anti-shake magnet 41a, and the second anti-shake magnetic component 82 is magnetically attracted to the second anti-shake magnet 42a, so that the anti-shake carrier 30 is attracted to the base 10, thereby holding the anti-shake carrier 30 on the base 10 and clamping the intermediate frame 20, the first support 61, and the second support 62; this magnetic attraction provides the anti-shake carrier 30 with a restoring force, so that it can return to its initial position when there is no driving current.

[0115] In some embodiments, the first anti-shake magnetic member 81 and the second anti-shake magnetic member 82 are fixed to the base 10. The first anti-shake magnetic member 81 is opposite to the first anti-shake magnet 41a along the optical axis direction C3, and the second anti-shake magnetic member 82 is opposite to the second anti-shake magnet 42a along the optical axis direction C3. In one specific embodiment, the first anti-shake magnetic member 81 and the second anti-shake magnetic member 82 are implemented as magnets to provide a stable magnetic attraction force.

[0116] Furthermore, please combine Figure 11 as well as Figure 13 As shown, in some embodiments, the magnetic attraction assembly 80 further includes a stabilization reset adjustment member 83. The stabilization reset adjustment member 83 is disposed on the side of the first stabilization magnetic attraction member 81 near the second stabilization magnetic attraction member 82, and is used to adjust the position of the resultant magnetic attraction force between the stabilization carrier 30 and the base 10, so as to reduce the risk of the stabilization carrier 30 tipping over relative to the base 10.

[0117] Specifically, the anti-shake reset adjustment component 83 can be made of a magnetic material. By changing its size, position or magnetic permeability, the distribution of the magnetic attraction force generated by the first anti-shake magnetic attraction component 81 and the second anti-shake magnetic attraction component 82 can be adjusted so that the point of application of the resultant magnetic attraction force is closer to the center of gravity of the anti-shake carrier 30, thereby improving the stability of the anti-shake motion.

[0118] Please refer to Figure 11 As shown, in some embodiments, the motor further includes a sensing component 90, which includes a first stabilization sensing element 91 and a second stabilization sensing element 92 for acquiring position change information of the stabilization carrier 30 relative to the base 10.

[0119] The first image stabilization sensing element 91 is fixed to the base 10 and is disposed opposite to the bottom surface of the first image stabilization magnet 41a. The first image stabilization sensing element 91 is located below the first image stabilization magnet 41a. By acquiring the magnetic field change information of the first image stabilization magnet 41a, the position change information of the first image stabilization magnet 41a is acquired, thereby acquiring the position change information of the image stabilization carrier 30 fixed to the first image stabilization magnet 41a (mainly acquiring the position change information of the image stabilization carrier 30 relative to the base 10 along the first direction C1). The second image stabilization sensing element 92 is fixed to the base 10 and is positioned opposite to the bottom surface of the second image stabilization magnet 42a. The second image stabilization sensing element 92 is located below the second image stabilization magnet 42a. By acquiring the magnetic field change information of the second image stabilization magnet 42a, the position change information of the second image stabilization magnet 42a is acquired, thereby acquiring the position change information of the image stabilization carrier 30 fixed to the second image stabilization magnet 42a (mainly acquiring the position change information of the image stabilization carrier 30 relative to the base 10 along the second direction C2).

[0120] The first image stabilization sensing element 91 and the second image stabilization sensing element 92 are electrically connected to the base conductive portion 71 and are respectively located between the first image stabilization coil 41b and the second image stabilization coil 42b. Specifically, the two sensing elements can be implemented as Hall sensors, tunnel magnetoresistive (TMR) sensors, or other magnetically sensitive elements with position sensing functions.

[0121] Please combine Figure 9 as well as Figure 14 As shown, in some embodiments, the motor of this application can also be used for the optical focusing function of the camera module. Specifically, the motor also includes a focusing carrier 100, which is movably disposed in the image stabilization carrier 30. The focusing carrier 100 is adapted to move relative to the image stabilization carrier 30 along the optical axis direction C3. The optical lens 1 is fixed to the focusing carrier 100, so that the image stabilization carrier 30 indirectly carries the optical lens 1 through the focusing carrier 100, and the focusing carrier 100 moves together with the image stabilization carrier 30 relative to the base 10 in a direction perpendicular to the optical axis.

[0122] Further, please refer to Figure 9 As shown, multiple focusing damping components 101 are also fixed on the top and bottom surfaces of the focusing carrier 100 to buffer the impact when the focusing carrier 100 and the top cover 50 collide and reduce the noise generated; the focusing damping components 101 are made of elastic materials, such as rubber, silicone or thermoplastic elastomers.

[0123] Specifically, the four corners of the top and bottom surfaces of the focusing carrier 100 are provided with focusing damping components 101. The focusing damping components 101 can be integrally molded into the focusing carrier 100 by injection molding to ensure the reliability of the connection.

[0124] Please combine Figure 9 as well as Figure 14 As shown, in some embodiments, the motor further includes a plurality of third support members 63 disposed between the focusing carrier 100 and the image stabilization carrier 30; the third support members 63 are used to maintain a gap between the focusing carrier 100 and the image stabilization carrier 30 and reduce the frictional resistance of the movement of the focusing carrier 100 relative to the image stabilization carrier 30.

[0125] Specifically, the third support 63 can be implemented as a ball, roller, slider, guide rod, or other rolling or sliding element suitable for reducing frictional resistance, and its number can be set to an odd or plural depending on the size and load requirements of the motor. In one specific embodiment, the third support 63 is implemented as a guide rod to provide precise guidance along the optical axis C3.

[0126] Furthermore, multiple third support members 63 are fixed to the image stabilization carrier 30. The focusing carrier 100 has focusing support grooves 102 on the side opposite to the third support members 63. The focusing support grooves 102 respectively accommodate the third support members 63, and at least one of the focusing support grooves 102 is a guide groove with a V-shaped cross section or an approximately V-shaped cross section, which is used to restrict the movement of the focusing carrier 100 relative to the image stabilization carrier 30 along the optical axis direction C3, and prevent the focusing carrier 100 from shifting in a plane perpendicular to the optical axis.

[0127] Please combine Figure 9 as well as Figure 15 As shown, in some embodiments, the focusing support groove 102 has multiple protrusions 103. By setting the protrusions 103, the friction between the focusing carrier 100 and the third support member 63 is reduced, making the focusing movement smoother.

[0128] Please combine Figure 9 as well as Figure 14 As shown, in some embodiments, the drive assembly 40 further includes a focusing magnet 110 and a focusing coil 120 for driving the focusing carrier 100 to move relative to the image stabilization carrier 30 along the optical axis direction C3. The focusing magnet 110 and the focusing coil 120 are arranged opposite each other in a direction perpendicular to the optical axis, specifically, opposite each other along a first direction C1. One of the focusing magnet 110 and the focusing coil 120 is fixed to the focusing carrier 100, and the other is fixed to the image stabilization carrier 30. In one specific embodiment, the focusing magnet 110 is fixed to the focusing carrier 100, and the focusing coil 120 is fixed to the image stabilization carrier 30.

[0129] Accordingly, the image stabilization carrier 30 also includes a third image stabilization carrier side 35, which is located opposite the first image stabilization carrier side 31 and connected to the second image stabilization carrier side 32. The focusing coil 120 is fixed to the third image stabilization carrier side 35. The focusing magnet 110 and the first image stabilization magnet 41a are arranged opposite each other on both sides of the motor to optimize the internal space layout of the motor.

[0130] To enhance the driving force of the focusing section, the focusing magnet 110 can also employ a Helbeck magnet structure. The focusing magnet 110 comprises multiple focusing magnet sections, wherein the magnetic poles of the central focusing magnet section are parallel to the optical axis, and the magnetic poles of the two side focusing magnet sections are perpendicular to the direction of the central focusing magnet section and arranged in opposite directions. This magnetic pole arrangement enhances the magnetic field strength near the focusing coil 120, thereby improving the focusing driving force.

[0131] In some embodiments, the focusing carrier 100 is further fixed with a focusing magnet magnetic guide, and the focusing magnet 110 is fixed to the focusing carrier 100 through the focusing magnet magnetic guide; the focusing magnet magnetic guide is made of a magnetic material, which can optimize the magnetic field distribution provided by the focusing magnet 110 to the focusing coil 120 on the one hand, and enhance the structural strength of the focusing carrier 100 on the other hand.

[0132] Please combine Figure 14 as well as Figure 16 As shown, in some embodiments, the conductive component 70 is also used to supply power to the focusing coil 120. Specifically, the conductive component 70 further includes a focusing conductive part 72, which includes a conductive fixing member 721, a conductive moving member 722, and a conductive connector 723.

[0133] The conductive movable component 722 is fixed to the focusing carrier 100, the focusing coil 120 is fixed and electrically connected to the conductive movable component 722, the conductive fixing component 721 is fixed to the base 10 and electrically connected to the conductive part 71 of the base, and the conductive connector 723 connects and electrically conducts the conductive movable component 722 and the conductive fixing component 721, thereby transmitting electrical energy to the focusing coil 120.

[0134] The conductive connector 723 extends on the top surface of the image stabilization carrier 30 and is arranged around the motor on multiple sides to reduce the resistance of the focusing conductive part 72 to the movement of the focusing carrier 100. Since the image stabilization carrier 30 can move in two dimensions relative to the base 10 in the horizontal plane, this arrangement allows the conductive connector 723 to have sufficient flexibility and length to adapt to this relative movement without affecting the stability of the electrical connection.

[0135] Please combine Figure 14 as well as Figure 16 As shown, in some embodiments, the conductive moving part 722 includes a vertical portion 7221 and a horizontal portion 7222 that are interconnected and electrically conductive; the focusing coil 120 is fixed to the vertical portion 7221; the top of the image stabilization carrier 30 is provided with a protrusion for fixing the horizontal portion 7222, the horizontal portion 7222 has a through hole at the position corresponding to the protrusion, and the portion extends downward so that the protrusion will not collide with the top cover 50 as the top of the image stabilization carrier 30.

[0136] The base 10 also includes a third base side portion 14 and a base side wall 15 extending upward from the third base side portion 14. A base conductive portion 71 extends from the third base side portion 14 to the base side wall 15 and protrudes from the top surface of the base side wall 15, thereby electrically connecting the conductive fastener 721 to the base conductive portion 71.

[0137] Please combine Figure 14 as well as Figure 16 As shown, in some embodiments, the magnetic attraction assembly 80 further includes a focusing magnetic attraction element 84; the focusing magnetic attraction element 84 is fixed to the image stabilization carrier 30, and the focusing magnetic attraction element 84 is implemented as an element suitable for magnetic attraction with a magnet, such as a magnet, a soft magnetic material block, etc.

[0138] The focusing magnetic 84 and the focusing magnet 110 attract each other, so that the focusing carrier 100 is attracted to the image stabilization carrier 30, thereby holding the focusing carrier 100 on the image stabilization carrier 30 and clamping the third support 63. This magnetic attraction provides the focusing carrier 100 with a restoring force, so that it can return to the initial focusing position when there is no driving current.

[0139] In some embodiments, the focusing magnetic chuck 84 is fixed to the vertical portion 7221 of the conductive movable member 722 on the side away from the focusing coil 120, thereby being fixed to the image stabilization carrier 30. The focusing magnetic chuck 84 is further provided with a plurality of focusing magnetic holes 841, which are used to adjust the position and distribution of the magnetic attraction between the focusing carrier 100 and the image stabilization carrier 30 to optimize the stability of the focusing motion.

[0140] Please refer to Figure 14 As shown, in some embodiments, the sensing component 90 further includes a focusing sensing element 93 for acquiring position change information of the focusing carrier 100 relative to the image stabilization carrier 30. The focusing sensing element 93 is fixed to the image stabilization carrier 30 and is disposed opposite to the focusing magnet 110. By acquiring the magnetic field change information of the focusing magnet 110, the position change information of the focusing magnet 110 is acquired, thereby acquiring the position change information of the focusing carrier 100 fixed to the focusing magnet 110 (mainly acquiring the position change information of the focusing carrier 100 relative to the image stabilization carrier 30 along the optical axis direction C3).

[0141] Furthermore, the focus sensing element 93 is disposed in the middle of the focus coil 120 and is fixed and electrically connected to the vertical portion 7221 of the conductive moving part 722. The focus sensing element 93 may be implemented as a Hall sensor, a tunnel magnetoresistive (TMR) sensor, or other magnetically sensitive element with position sensing function.

[0142] The aforementioned focusing carrier 100 and its related components are integrated with the image stabilization function of the intermediate frame 20, realizing the combined function of optical image stabilization and optical focusing. The intermediate frame 20 decomposes the two-dimensional motion of the image stabilization carrier 30 into two vertical motions, while the focusing carrier 100 moves along the optical axis C3 inside the image stabilization carrier 30. The two work independently and collaboratively to jointly realize the multi-functional drive of the camera module.

[0143] This application also provides a camera module, including an optical lens 1, a photosensitive module and the aforementioned motor; the optical lens 1 is disposed on the image stabilization carrier 30 and is used to receive and emit light along its own optical axis direction C3; the photosensitive module is disposed on the base 10 and is used to receive the light emitted from the optical lens 1 for imaging.

[0144] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0145] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
