[0002] With the widespread use of mobile electronic devices, the technology related to camera modules used in these devices to help users acquire images has developed and progressed rapidly.

[0003] Currently, consumers in the market have increasingly higher and more diverse requirements for the functions of camera modules configured in mobile electronic devices (such as smartphones). For example, in order to achieve common optical focusing and optical image stabilization functions, a motor that can drive the optical lens to move is usually set in the camera module, thereby adjusting the optical performance by driving the optical lens to move.

[0004] However, with increasing consumer demand, the performance requirements for motors in camera modules are becoming more stringent, inevitably leading to an increase in motor size, which contradicts the miniaturization trend of camera modules.

[0033] The following description is provided to enable those skilled in the art to implement the invention. Other obvious substitutions, modifications, and variations will arise for those skilled in the art. Therefore, the scope of protection of this invention should not be limited to the exemplary embodiments described herein.

[0034] Those skilled in the art will understand that, unless specifically indicated herein, the term "a" should be understood as "at least one" or "one or more," meaning that in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple.

[0035] Those skilled in the art will understand that, unless specifically indicated herein, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., refer to the orientation or position based on the accompanying drawings, and are merely for the purpose of describing the invention, and do not indicate or imply that the apparatus or element involved must have a specific orientation or position. Therefore, the above terms should not be construed as limiting the invention.

[0036] Refer to the accompanying drawings of this invention. Figure 1 To be continued Figure 18 A camera module and its motor according to an embodiment of the present invention are described. The camera module includes an optical lens 10, a photosensitive component 11, and a motor 2, wherein the motor 2 is disposed on the photosensitive component 11, and the optical lens 10 is held on the photosensitive path of the photosensitive component 11 by the motor 2. The photosensitive component 11 is used to receive light emitted from the optical lens 10 to form an image of the subject. The motor 2 is adapted to drive the optical lens 10 to move to achieve optical performance adjustment, for example, to achieve functions such as optical focusing and optical image stabilization. The optical lens 10 has an optical axis O, and the photosensitive component 11 and the optical lens 10 are disposed opposite each other along the optical axis O. For ease of subsequent description, the direction parallel to the optical axis O is referred to as the longitudinal direction, and the direction perpendicular to the optical axis O is referred to as the transverse direction.

[0037] As attached Figure 2 As shown, the photosensitive component 11 includes an imaging circuit board 111, a photosensitive chip 112 electrically connected to the imaging circuit board 111, and at least one electronic component 113. The photosensitive chip 112 is used to receive light reflected from the subject collected by the optical lens 10 for imaging, and the photosensitive chip 112 is electrically connected to an electronic device through the imaging circuit board 111. The electronic component 113 can be one or more passive electronic devices such as resistors and capacitors, or one or more active electronic devices such as driver chips and memory chips.

[0038] In some embodiments of the present invention, the photosensitive component 11 further includes a filter element 114, which is held on the photosensitive path of the photosensitive chip 112 to filter the light incident on the photosensitive chip 112 and filter out light that is not needed for imaging (e.g., infrared light).

[0039] In some embodiments of the present invention, the photosensitive assembly 11 further includes a bracket 115, on which the filter element 114 is mounted. The bracket 115 is fixed to the imaging circuit board 111, thereby holding the filter element 114 on the photosensitive path of the photosensitive chip 112 via the bracket 115. Correspondingly, the motor 2 can be fixed to the photosensitive assembly 11 by being fixed to the bracket 115. Optionally, the motor 2 can also be fixed to the photosensitive assembly 11 by being fixed to the imaging circuit board 111. In this case, if the photosensitive assembly 11 still has the bracket 115, the bracket 115 is recessed relative to the edge of the imaging circuit board 111 to avoid the motor 2, thereby providing space for fixing the motor 2.

[0040] Understandable, attached Figure 2 The specific structure of the photosensitive component 11 shown is only for illustration to clarify the overall solution of the present invention. It should not constitute a limitation on the protection scope of the camera module of the present invention. Any photosensitive component that can achieve the same or similar functions belongs to the optional implementation of the present invention and should be covered within the protection scope of the present invention.

[0041] As attached Figure 1 To be continued Figure 3 As shown, the camera module also includes a cover 12, which covers the motor 2 and has a window 120 to expose the optical lens 10, so that the optical lens 10 can receive the light reflected from the subject.

[0042] As attached Figure 2 To be continued Figure 18As shown, the motor 2 includes a base 3, a frame 4, a carrier 5, and a drive assembly 6. The carrier 5 carries the optical lens 10 of the camera module and is movably disposed within the frame 4. The drive assembly 6 is configured to drive the carrier 5 to move relative to the frame 4 in the longitudinal direction (i.e., parallel to the optical axis O), thereby allowing the carrier 5 and the optical lens 10 fixed to the carrier 5 to move along the longitudinal direction under the drive of the drive assembly 6, thus achieving the optical focusing function of the camera module. The frame 4 is movably disposed on the base 3, and the drive assembly 6 is also configured to drive the frame 4 to move relative to the base 3 in the transverse direction (i.e., perpendicular to the optical axis O), thereby allowing the frame 4 and the carrier 5 disposed on the frame 4 to move along the transverse direction under the drive of the drive assembly 6, and further allowing the optical lens 10 fixed to the carrier 5 to move along the transverse direction under the drive of the drive assembly 6, thus achieving the optical image stabilization function of the camera module.

[0043] As attached Figure 2 Appendix Figure 3 and attached Figure 6 As shown, the driving assembly 6 includes a focusing driving assembly 61, which drives the carrier 5 to move relative to the frame 4 along the longitudinal direction. The focusing driving assembly 61 includes a focusing magnet 611 and a focusing coil 612, which are disposed opposite to each other. One of the focusing magnet 611 and the focusing coil 612 is disposed on the frame 4, and the other is disposed on the carrier 5. In some embodiments of the present invention, the focusing magnet 611 is disposed on the carrier 5, and the focusing coil 612 is disposed on the frame 4. Optionally, in other embodiments of the present invention, the focusing magnet 611 is disposed on the frame 4, and the focusing coil 612 is disposed on the carrier 5.

[0044] As attached Figure 2 and attached Figure 6 As shown, the focusing magnet 611 and the focusing coil 612 are both located on the first side 201 of the motor 2. The focusing magnet 611 is disposed on the side of the carrier 5 located on the first side 201, and the focusing coil 612 is disposed on the side of the frame 4 located on the first side 201, so that the focusing magnet 611 and the focusing coil 612 are arranged opposite to each other. In particular, the focusing coil 612 is arranged longitudinally, that is, the center line of the coil hole of the focusing coil 612 is perpendicular to the optical axis O, and the focusing coil 612 and the focusing magnet 611 are arranged opposite to each other in a direction perpendicular to the longitudinal direction.

[0045] Continue to refer to the appendix Figure 2 and attached Figure 6 The motor 2 further includes a focusing magnetic sheet 613, which enhances the magnetic field strength of the focusing magnet 611. The focusing magnetic sheet 613 is positioned on the side of the focusing magnet 611 away from the focusing coil 612. Preferably, the focusing magnet 611 is fixed to the focusing magnetic sheet 613 on one side of the carrier 5. For example, the focusing magnetic sheet 613 is first embedded in the carrier 5, and then the focusing magnet 611 is fixed to the focusing magnetic sheet 613.

[0046] As attached Figure 2 To be continued Figure 6 As shown, the motor 2 also includes a focusing circuit board 614. The frame fixing portion 6141 of the focusing circuit board 614 is fixed to the outer side of the frame 4 on the side of the first side 201. The focusing coil 612 is fixed to the frame fixing portion 6141 of the focusing circuit board 614 and electrically connected to the focusing circuit board 614, wherein the focusing coil 612 is fixed to the frame fixing portion 6141 on the side near the focusing magnet 611. The frame 4 has a frame opening 400, which is formed on the side of the frame 4 on the first side 201. The focusing coil 612 is at least partially accommodated in the frame opening 400. In other words, the focusing coil 612 is disposed on the side of the frame 4 on the first side 201 by being fixed to the frame fixing portion 6141 of the focusing circuit board 614. Figure 3 As shown, the frame 4 is provided with a frame positioning protrusion 401, which protrudes outward from the outer side of the frame 4 located on the first side 201. The focusing circuit board 614 is provided with a frame positioning hole 6140 located on the frame fixing part 6141. The frame positioning protrusion 401 and the frame positioning hole 6140 match and correspond to each other, so that the frame positioning protrusion 401 can pass through the frame positioning hole 6140, thereby facilitating the fixing of the frame fixing part 6141 of the focusing circuit board 614 to the outer side of the frame 4 located on the first side 201, which is beneficial to improving accuracy and reliability.

[0047] As attached Figure 2 and attached Figure 6As shown, the motor 2 further includes a focus position sensing element 615, which is fixed to and electrically connected to the focus circuit board 614. The focus position sensing element 615 is disposed opposite to the focus magnet 611 and is used to sense changes in the magnetic field of the focus magnet 611 to obtain positional change information of the focus magnet 611 and the carrier 5 in the longitudinal direction. Preferably, the focus position sensing element 615 is disposed within the coil hole of the focus coil 612, and is fixed to the frame fixing portion 6141 of the focus circuit board 614.

[0048] As attached Figure 2 To be continued Figure 4 and appendix Figure 6 As shown, the motor 2 also includes a focusing magnetic chuck 616, which is disposed on the side of the focusing coil 612 away from the focusing magnet 611 and on the side of the frame 4 located on the first side 201. It can be understood that the carrier 5 is supported within the frame 4 by the magnetic attraction between the focusing magnetic chuck 616 and the focusing magnet 611. Preferably, the focusing magnetic chuck 616 is fixed (e.g., by adhesive bonding) to the side of the frame fixing portion 6141 of the focusing circuit board 614 away from the focusing magnet 611, thereby the focusing magnetic chuck 616 is disposed on the side of the frame 4 located on the first side 201 by being fixed to the frame fixing portion 6141 of the focusing circuit board 614. The focusing magnetic accumulator 616 is provided with a positioning hole 6160, which matches and corresponds to the frame positioning protrusion 401. This allows the frame positioning protrusion 401 to pass through the frame positioning hole 6140 and then further penetrate or even pass through the positioning hole 6160. This facilitates fixing the focusing magnetic accumulator 616 to the side of the frame fixing part 6141 of the focusing circuit board 614 away from the focusing magnet 611, thereby improving accuracy and reliability.

[0049] As attached Figure 3 Appendix Figure 4 Appendix Figure 6 and attached Figure 7As shown, the focusing magnetic accumulator 616 has at least one hollow hole 6161. The hollow hole 6161 extends along the longitudinal direction and is elongated. By providing the hollow hole 6161, the longitudinal restoring force between the focusing magnetic accumulator 616 and the focusing magnet 611 can be reduced, that is, the magnetic attraction force between the focusing magnetic accumulator 616 and the focusing magnet 611 that is parallel to the optical axis O and hinders the realization of the optical focusing function can be reduced. It is understandable that, as the focusing magnet 611 moves along the longitudinal direction with the carrier 5, the center of the focusing magnet 611 and the center of the focusing magnetic accumulator 616 cannot always remain aligned. Consequently, the magnetic attraction between the focusing magnetic accumulator 616 and the focusing magnet 611 cannot always be perpendicular to the optical axis O. Therefore, the magnetic attraction component between the focusing magnetic accumulator 616 and the focusing magnet 611, parallel to the optical axis O, is the resistance to achieving the optical focusing function and can be called the longitudinal restoring force. The greater the longitudinal restoring force, the more detrimental it is to the realization of the optical focusing function.

[0050] As attached Figure 7 As shown, the perforated hole 6161 is elongated, meaning that the height H of the perforated hole 6161 is greater than the width W of the perforated hole 6161. The height direction of the perforated hole 6161 is parallel to the optical axis O, and the width direction of the perforated hole 6161 is perpendicular to the optical axis O. By setting the elongated perforated hole 6161, the longitudinal restoring force between the focusing magnetic plate 616 and the focusing magnet 611 can be effectively reduced, thereby enhancing the performance of the motor 2 and the camera module.

[0051] Continue to refer to the appendix Figure 7 Preferably, the focusing magnetic accumulator 616 has a plurality of hollow holes 6161, which are spaced apart from each other. The plurality of hollow holes 6161 collectively define a coverage width range R. Figure 7 In the direction where the focusing magnetic accumulator 616 and the focusing magnet 611 are positioned opposite each other, the coverage width R completely covers the width range r of the focusing magnet 611, thereby greatly reducing the longitudinal restoring force. Actual testing has verified that by setting multiple perforations 6161, the ratio of the longitudinal restoring force to the magnetic attraction force along the direction where the focusing magnetic accumulator 616 and the focusing magnet 611 are positioned opposite each other is less than 1:100. In a specific example, the longitudinal restoring force is 0.5 mN, while the magnetic attraction force along the direction where the focusing magnetic accumulator 616 and the focusing magnet 611 are positioned opposite each other is 80 mN; the ratio is only 1:160, greatly reducing the longitudinal restoring force and thus significantly weakening its obstruction to optical focusing.

[0052] It is worth mentioning that, in the initial state of the motor 2, the center of the focusing magnet 611 and the center of the hollow hole 6161 are at the same height in the longitudinal direction (i.e., the height direction), so that the longitudinal restoring force experienced by the carrier 5 when it moves upward or downward is similar, thereby facilitating the drive control of the motor 2.

[0053] As attached Figure 3 and appendix Figure 8 To be continued Figure 13 As shown, the motor 2 further includes a focusing support 617, which is disposed between the carrier 5 and the frame 4. The carrier 5 and the frame 4 clamp the focusing support 617 under the magnetic attraction of the focusing magnetic plate 616 and the focusing magnet 611. The carrier 5 is movably supported in the frame 4 by the focusing support 617. The carrier 5 has a first carrier side guide groove 51 and a second carrier side guide groove 52. Both the first carrier side guide groove 51 and the second carrier side guide groove 52 are formed on the outer side of the carrier 5 located on the first side 201, and are respectively located on both sides of the focusing magnet 611. The frame 4 is provided with a first frame side guide groove 41 and a second frame side guide groove 42. Both the first frame side guide groove 41 and the second frame side guide groove 42 are formed on the inner side of the frame 4 located on the first side 201, and are located on opposite sides of the focusing coil 612. The first carrier side guide groove 51, the second carrier side guide groove 52, the first frame side guide groove 41, and the second frame side guide groove 42 all extend along the longitudinal direction. The first carrier side guide groove 51 and the first frame side guide groove 41 are arranged opposite each other to form a first accommodating space between them. The second carrier side guide groove 52 and the second frame side guide groove 42 are arranged opposite each other to form a second accommodating space between them. The focusing support 617 is accommodated in the first accommodating space and the second accommodating space.

[0054] As attached Figure 3 and appendix Figure 8 To be continued Figure 12As shown, in some embodiments of the present invention, the focusing support portion 617 includes at least two first focusing support balls 6171 and at least one second focusing support ball 6172. The first focusing support balls 6171 are disposed between the first carrier-side guide groove 51 and the first frame-side guide groove 41, and are housed within the first receiving space. The first focusing support balls 6171 are capable of rolling within the first receiving space and / or sliding to a certain extent along the longitudinal direction. The second focusing support balls 6172 are disposed between the second carrier-side guide groove 52 and the second frame-side guide groove 42, and are housed within the second receiving space. The second focusing support balls 6172 are capable of rolling within the second receiving space and / or sliding to a certain extent along the longitudinal direction. The number of first focusing support balls 6171 is greater than the number of second focusing support balls 6172. Therefore, the first focusing support balls 6171, the first carrier side guide groove 51, and the first frame side guide groove 41 provide the primary guiding function for the longitudinal movement of the carrier 5, while the second focusing support balls 6172, the second carrier side guide groove 52, and the second frame side guide groove 42 provide auxiliary guiding function for the longitudinal movement of the carrier 5. Preferably, the dimensions of the first focusing support balls 6171 and the second focusing support balls 6172 are the same.

[0055] Therefore, the longitudinal dimension of the second accommodating space required for the second focusing support ball 6172 can be smaller than the longitudinal dimension of the first accommodating space required for the first focusing support ball 6171. Further considering the positional and mating relationships between the various components of the motor 2, and the inventive avoidance design that the carrier 5 can make, this invention creatively proposes an implementation method that reduces the longitudinal dimension of the second carrier side guide groove 52. (See attached...) Figure 3 Appendix Figure 9 Appendix Figure 11 and attached Figure 12As shown, the second carrier-side guide groove 52 has a lower groove wall 521, which is located at the middle of the carrier 5 in the longitudinal direction. This allows the second carrier-side guide groove 52 to extend only to the lower groove wall 521 from the top of the carrier 5 in the longitudinal direction, while the first carrier-side guide groove 51 extends from the top to the bottom of the carrier 5 in the longitudinal direction. Thus, the longitudinal dimension of the first carrier-side guide groove 51 is larger than the longitudinal dimension of the second carrier-side guide groove 52, and the second carrier-side guide groove 52 does not extend to the bottom of the carrier 5 in the longitudinal direction. This allows for the provision of necessary clearance structures below the second carrier-side guide groove 52, which will be further elaborated in the subsequent description. It is understood that the lower groove wall 521 prevents the second focusing support ball 6172 from falling off from below, serving as a limiting and anti-detachment function. Accordingly, as shown in the attached... Figure 10 As shown, the first frame side guide groove 41 has a groove bottom wall 411, which is located at the bottom of the frame 4 in the longitudinal direction. The groove bottom wall 411 can prevent the first focusing support ball 6171 from falling off from below, thus playing a limiting and anti-detachment role. It is worth mentioning that in the longitudinal direction, the position of the lower groove wall 521 is always higher than the position of the groove bottom wall 411.

[0056] As attached Figure 3 and appendix Figure 9 To be continued Figure 12As shown, the motor 2 further includes a stop 618, which is fixed to the carrier 5. The stop 618 includes a first stop arm 6181 and a second stop arm 6182. The first stop arm 6181 extends above the first carrier side guide groove 51 in the longitudinal direction but does not extend into the first carrier side guide groove 51, thereby preventing the first focusing support ball 6171 from dislodging from above while providing sufficient longitudinal dimension for the first accommodating space. The second stop arm 6182 extends into the second carrier side guide groove 52 to further restrict the movable space of the second focusing support ball 6172 and prevent the second focusing support ball 6172 from dislodging from above. It can be understood that by providing the stop 618, the assembly of the first focusing support ball 6171 and the second focusing support ball 6172 can be made easier. Specifically, after the carrier 5 and the frame 4 are aligned and assembled, the first focusing support ball 6171 can be inserted from above between the first carrier side guide groove 51 and the first frame side guide groove 41, and the second focusing support ball 6172 can also be inserted from above between the second carrier side guide groove 52 and the second frame side guide groove 42. Then the stop 618 is fixed to the carrier 5 so that the first focusing support ball 6171 and the second focusing support ball 6172 cannot come out from above.

[0057] As attached Figure 13 As shown, in some optional embodiments of the present invention, the focusing support 617 may no longer be implemented as a focusing support ball bearing, but as two focusing support guide rods. One focusing support guide rod is disposed between the first carrier-side guide groove 51 and the first frame-side guide groove 41, and the other focusing support guide rod is disposed between the second carrier-side guide groove 52 and the second frame-side guide groove 42. The focusing support guide rods can be fixed to the carrier 5 or the frame 4, thereby eliminating the need for the stop member 618. Preferably, the longitudinal dimension of the focusing support guide rod disposed between the second carrier-side guide groove 52 and the second frame-side guide groove 42 is smaller than the longitudinal dimension of the focusing support guide rod disposed between the first carrier-side guide groove 51 and the first frame-side guide groove 41. In this way, the second carrier-side guide groove 52 still has the lower groove wall 521 located at the middle position of the carrier 5 in the longitudinal direction, so that the necessary clearance structure can be provided below the second carrier-side guide groove 52.

[0058] As attached Figure 3 To be continued Figure 5As shown, the focusing circuit board 614, while being fixed to the frame 4, must also be electrically connected to the conductive circuit 31 embedded in the base 3. That is, the focusing circuit board 614 should also have a portion fixed to the base 3 to ensure the stability and reliability of the electrical connection between the focusing circuit board 614 and the conductive circuit 31. In other words, the focusing circuit board 614 is simultaneously fixed to both the frame 4 and the base 3. Since the frame 4 moves relative to the base 3 in the lateral direction under the driving action of the driving assembly 6, the focusing circuit board 614 will inevitably hinder the relative movement between the frame 4 and the base 3, inevitably generating additional resistance. To reduce the resistance caused by the focusing circuit board 614 to the movement of the frame 4 relative to the base 3, the focusing circuit board 614 extends from the side of the frame 4 located on the first side 201 to the side of the base 3 located on the second side 202 of the motor 2, wherein the first side 201 and the second side 202 of the motor 2 are opposite to each other. In other words, the focusing circuit board 614 extends from one side of the frame 4 to the opposite side, that is, from the first side 201 of the motor 2 to the second side 202 of the motor 2, thereby extending the length of the focusing circuit board 614 and helping to reduce the resistance brought by the focusing circuit board 614.

[0059] Continue to refer to the appendix Figure 3 To be continued Figure 5The focusing circuit board 614 includes the frame fixing part 6141, the base fixing part 6142 and the connecting part 6143. The connecting part 6143 connects the frame fixing part 6141 and the base fixing part 6142 and realizes electrical conduction between them. The connecting part 6143 is preferably a flexible circuit board. The frame fixing part 6141 is fixed to the outer side of the frame 4 located on the first side 201, the base fixing part 6142 is fixed to the outer side of the base 3 located on the second side 202, and the connecting part 6143 extends bent between the frame fixing part 6141 and the base fixing part 6142. The connecting part 6143 includes a first connecting strap 6144 and a second connecting strap 6145. The two ends of the first connecting strap 6144 are electrically connected to the frame fixing part 6141 and the second connecting strap 6145, respectively, and the two ends of the second connecting strap 6145 are electrically connected to the base fixing part 6142 and the first connecting strap 6144, respectively. The first connecting strap 6144 is inclined relative to the outer side of the third side 203 of the motor 2 relative to the frame 4, and the second connecting strap 6145 is inclined relative to the outer side of the second side 202 of the motor 2 relative to the frame 4, and the included angle between the first connecting strap 6144 and the second connecting strap 6145 is an obtuse angle, thereby better reducing the resistance brought by the focusing circuit board 614, wherein the third side 203 of the motor 2 is the adjacent side of the first side 201 and the second side 202. The frame 4 has a first accommodating groove 43 extending at an angle at the top of the third side 203, and a second accommodating groove 44 extending at an angle between the frame 4 and the carrier 5. The second accommodating groove 44 is formed between the top of the frame 4 and the carrier 5 at the second side 202. The first connecting strip 6144 is at least partially accommodated in the first accommodating groove 43, and the second connecting strip 6145 is at least partially accommodated in the second accommodating groove 44. Thus, the frame 4 can provide a certain degree of shielding and protection for the first connecting strip 6144 and the second connecting strip 6145 on the outside, thereby reducing the risk of the first connecting strip 6144 and the second connecting strip 6145 being damaged on the outside, thereby enhancing the reliability of the motor 2 and thus helping to extend the service life of the motor 2 and the camera module. It is understood that the first connecting strip 6144 and the second connecting strip 6145 are both inclined and the included angle between them is an obtuse angle. This arrangement can greatly reduce the obstruction of the focusing circuit board 614 to the frame 4 moving relative to the base 3 in the lateral direction, and is more conducive to reducing the resistance brought by the focusing circuit board 614.

[0060] Continue to refer to the appendix Figure 3 To be continued Figure 5The motor 2 further includes two shaping portions 6146 for maintaining the curved shape of the focusing circuit board 614. One shaping portion 6146 is located at the bend where the first connecting strap 6144 and the frame fixing portion 6141 connect, and is situated at the corner of the motor 2 between the first side 201 and the third side 203. The other shaping portion 6146 is located at the bend where the second connecting strap 6145 and the first connecting strap 6144 connect, and is situated at the corner of the motor 2 between the third side 203 and the second side 202. It is worth noting that the shaping portion 6146 can be made of materials such as metal or plastic to maintain its own curved shape, thereby maintaining the curved shape of the focusing circuit board 614. The shaping portion 6146 is fixed by directly attaching it to the bend of the focusing circuit board 614, such as by adhesive bonding. Preferably, the shaping portion 6146 is a curved frame shape, thereby reducing the weight of the shaping portion 6146 and avoiding excessive resistance to the movement of the frame 4 relative to the base 3 in the lateral direction due to the shaping portion 6146. It is also worth mentioning that the shaping portion 6146 is disposed on the outside of the curved portion of the focusing circuit board 614, providing a certain degree of protection to the curved portion of the focusing circuit board 614 from external damage.

[0061] As attached Figure 5 As shown, the base 3 is provided with at least one base positioning protrusion 301, which protrudes outward from the outer side of the base 3 located on the second side 202. The focusing circuit board 614 is provided with at least one base positioning hole 6147 located on the base fixing part 6142. The base positioning protrusion 301 and the base positioning hole 6147 match and correspond to each other, so that the base positioning protrusion 301 can pass through the base positioning hole 6147, thereby facilitating the fixing of the base fixing part 6142 of the focusing circuit board 614 to the outer side of the base 3 located on the second side 202, which is beneficial to improving accuracy and reliability. The conductive circuit 31 is provided with a focusing circuit board connection end 311, which is exposed on the side of the base 3 located on the second side 202, so as to be welded to the concave pad of the base fixing part 6142 of the focusing circuit board 614, thereby realizing the electrical connection between the conductive circuit 31 and the focusing circuit board 614.

[0062] As attached Figure 2 Appendix Figure 3 Appendix Figure 6 and appendix Figure 14 To be continued Figure 17As shown, the drive assembly 6 further includes an image stabilization drive assembly 62, which drives the frame 4 to move relative to the base 3 in the lateral direction. The image stabilization drive assembly 62 is disposed on other sides of the motor 2 where the focusing drive assembly 61 is not located, such as the second side 202, the third side 203, and / or the fourth side 204 of the motor 2. In other words, by disposing of the image stabilization drive assembly 62 and the focusing drive assembly 61 on different sides of the motor 2, it is possible to avoid the image stabilization drive assembly 62 and the focusing drive assembly 61 overlapping each other in the longitudinal direction, thereby reducing the longitudinal dimension of the motor 2 and facilitating the miniaturization of the motor 2 and the camera module. Furthermore, since the image stabilization drive assembly 62 and the focusing drive assembly 61 are disposed on different sides of the motor 2, there is no mutual magnetic interference between them, which enhances the performance and reliability of the motor 2 and the camera module. The motor 2 has four sides: a first side 201, a second side 202, a third side 203, and a fourth side 204. The first side 201 and the second side 202 are opposite to each other, as are the third side 203 and the fourth side 204. The third side 203 is adjacent to both the first side 201 and the second side 202, and the fourth side 204 is also adjacent to both the first side 201 and the second side 202. The anti-shake drive assembly 62 includes at least one anti-shake magnet 621 and at least one anti-shake coil 622. The anti-shake magnet 621 and the corresponding anti-shake coil 622 are arranged opposite to each other. One of the anti-shake magnet 621 and the anti-shake coil 622 is disposed on the frame 4, and the other is disposed on the base 3. In some embodiments of the present invention, the anti-shake magnet 621 is disposed on the frame 4, and the anti-shake coil 622 is disposed on the base 3. Optionally, in other embodiments of the present invention, the anti-shake magnet 621 is disposed on the base 3, and the anti-shake coil 622 is disposed on the frame 4.

[0063] As attached Figure 3 Appendix Figure 14 and attached Figure 15As shown, the image stabilization magnet 621 is disposed on the frame 4 and located at the bottom of the frame 4 in the longitudinal direction, while the image stabilization coil 622 is disposed on the base 3 and located at the top of the base 3 in the longitudinal direction, thus the image stabilization magnet 621 and the image stabilization coil 622 are arranged opposite to each other. Specifically, the image stabilization coil 622 is arranged laterally, that is, the center line of the coil hole of the image stabilization coil 622 is parallel to the optical axis O, and the image stabilization coil 622 and the image stabilization magnet 621 are arranged opposite to each other along the longitudinal direction. It can be understood that the arrangement of the image stabilization coil 622 laterally at the top of the base 3 in the longitudinal direction, compared to the arrangement of it vertically at the top of the base 3 in the longitudinal direction, is beneficial for reducing the longitudinal dimension of the motor 2, thereby facilitating the miniaturization of the motor 2 and the camera module. It can also be understood that the arrangement of the image stabilization coil 622 located on the lower side of the frame 4 in the longitudinal direction, compared to its location on the outer side of the frame 4, is beneficial for reducing the lateral size of the motor 2, thereby facilitating the miniaturization of the motor 2 and the camera module. Therefore, the arrangement of the image stabilization drive component 62 and the focus drive component 61 provided by the present invention, which are located on different sides of the motor 2 and the image stabilization coil 622 is laterally arranged on the top of the base 3 in the longitudinal direction, is beneficial for reducing not only the longitudinal size of the motor 2 but also its lateral size.

[0064] Continue to refer to the appendix Figure 3 Appendix Figure 14 and attached Figure 15 Preferably, the image stabilization drive assembly 62 includes three image stabilization magnets 621 and three image stabilization coils 622. One image stabilization magnet 621 is disposed at the bottom of the frame 4 on the side of the third side 203, and one image stabilization coil 622 is disposed at the top of the base 3 on the side of the third side 203. The other two image stabilization magnets 621 are disposed at the bottom of the frame 4 on the side of the second side 202, and the other two image stabilization coils 622 are disposed at the top of the base 3 on the side of the second side 202.

[0065] As attached Figure 2 Appendix Figure 6 and attached Figure 15As shown, the motor 2 further includes at least one anti-shake magnetic sheet 623, which is used to enhance the magnetic field strength of the corresponding anti-shake magnet 621. The anti-shake magnetic sheet 623 is disposed on the side of the corresponding anti-shake magnet 621 away from the corresponding anti-shake coil 622. Preferably, the anti-shake magnet 621 is disposed at the bottom of the frame 4 in a manner fixed to the corresponding anti-shake magnetic sheet 623. For example, the anti-shake magnetic sheet 623 is first embedded in the bottom of the frame 4, and then the anti-shake magnet 621 is fixed to the corresponding anti-shake magnetic sheet 623.

[0066] As attached Figure 14 As shown, the motor 2 also includes a stabilization circuit board 624, which is fixed to the top surface of the base 3 in the longitudinal direction. The stabilization coil 622 is fixed to the top surface of the stabilization circuit board 624 in the longitudinal direction and electrically connected to the stabilization circuit board 624, thereby placing the stabilization coil 622 at the top of the base 3 in the longitudinal direction. In other words, the stabilization coil 622 is placed at the top of the base 3 in a manner that it is fixed to the stabilization circuit board 624.

[0067] Continue to refer to the appendix Figure 14 Preferably, the image stabilization circuit board 624 has multiple pads on its top surface in the longitudinal direction. The image stabilization coil 622 can be connected by electrical connection wires (not shown in the figure) to the corresponding pads, thereby achieving electrical connection between the image stabilization coil 622 and the image stabilization circuit board 624. It is understood that... Figure 14 The positions of the pads shown for electrical connection with the anti-shake coil 622 are for illustrative purposes only. In other embodiments of the present invention, the positions of the pads can be adjusted according to actual needs.

[0068] As attached Figure 14 Appendix Figure 16 and attached Figure 17 As shown, the conductive circuit 31 also includes anti-shake circuit board connection terminals 312, which are exposed on the top surface of the base 3 to facilitate soldering to pads on the bottom surface of the anti-shake circuit board 624, thereby achieving electrical connection between the conductive circuit 31 and the anti-shake circuit board 624. Preferably, the conductive circuit 31 has four anti-shake circuit board connection terminals 312 exposed on the top surface of the base 3, and correspondingly, the bottom surface of the anti-shake circuit board 624 has four pads for electrical connection with the conductive circuit 31.

[0069] As attached Figure 4 Appendix Figure 5 Appendix Figure 14 and attached Figure 16As shown, the conductive circuit 31 also includes a photosensitive component connection terminal 313, which is exposed on the base 3 and used for electrical connection with the photosensitive component 11 of the camera module. Preferably, the photosensitive component connection terminal 313 is exposed on the side of the base 3 located on the third side 203.

[0070] As attached Figure 16 As shown, the motor 2 further includes at least one anti-shake position sensing element 625. The anti-shake position sensing element 625 is fixed to and electrically connected to the anti-shake circuit board 624. The anti-shake position sensing element 625 is used to sense the magnetic field change of the corresponding anti-shake magnet 621 to obtain position change information of the anti-shake magnet 621 and the frame 4 in the lateral direction. Preferably, the anti-shake position sensing element 625 is disposed on the bottom surface of the anti-shake circuit board 624, that is, on the side of the anti-shake circuit board 624 away from the anti-shake coil 622. The anti-shake position sensing element 625 is disposed directly below the corresponding anti-shake coil 622, thereby corresponding to the corresponding anti-shake magnet 621. Accordingly, to accommodate the anti-shake position sensing element 625, the base 3 is provided with at least one sensing element receiving groove 302, which is formed by a downward recess from the top surface of the base 3. When the motor 2 is provided with three anti-shake magnets 621 and three anti-shake coils 622, the motor 2 is provided with three anti-shake position sensing elements 625, and the base 3 is provided with three sensing element receiving slots 302, in which the anti-shake position sensing elements 625 are received. It can be understood that placing the anti-shake position sensing elements 625 on the bottom surface of the anti-shake circuit board 624, compared to placing them on the top surface, helps to reduce the lateral dimension of the motor 2, thereby facilitating the miniaturization of the motor 2 and the camera module. It can also be understood that forming the sensing element receiving slots 302 with a downward recess on the top surface of the base 3 to accommodate the anti-shake position sensing elements 625 helps to reduce the longitudinal dimension of the motor 2, thereby facilitating the miniaturization of the motor 2 and the camera module.

[0071] As attached Figure 17As shown, the motor 2 further includes at least one anti-shake magnetic plate 626, which is disposed on the side of the corresponding anti-shake coil 622 away from the corresponding anti-shake magnet 621, and is disposed on the base 3. It can be understood that the frame 4 is stably supported on the base 3 by the magnetic attraction between the anti-shake magnetic plate 626 and the corresponding anti-shake magnet 621. The anti-shake magnetic plate 626 can be directly fixed to the base 3 by bonding or insert molding, or indirectly fixed to the base 3 by fixing to the anti-shake circuit board 624. Preferably, the anti-shake magnetic plate 626 is directly fixed to the base 3. This direct fixing to the base 3 helps reduce the complexity of the process and also reduces the difficulty of aligning and fixing the anti-shake circuit board 624 and the base 3. In some embodiments of the present invention, the base 3 is provided with at least one magnetic accommodating groove 303, which is formed by a downward indentation from the top surface of the base 3, and the anti-shake magnetic accommodating piece 626 is disposed in the magnetic accommodating groove 303. Preferably, the motor 2 includes two anti-shake magnetic accommodating pieces 626, one of which is located on the third side 203 of the motor 2, corresponding to one anti-shake magnet 621 located on the third side 203, and the other is located on the second side 202 of the motor 2, corresponding to the two anti-shake magnets 621 located on the second side 202.

[0072] It is worth mentioning that by providing the magnetic accommodating groove 303 to accommodate the anti-shake magnetic accommodating piece 626, rather than embedding the anti-shake magnetic accommodating piece 626 into the base 3 through an insert molding process, the lateral dimension of the motor 2 is reduced. It should be understood that if the anti-shake magnetic accommodating piece 626 were fixed using an insert molding method, the base 3 would need to wrap around the sides of the anti-shake magnetic accommodating piece 626, which would increase the lateral dimension of the base 3.

[0073] Continue to refer to the appendix Figure 17The image stabilization magnetic stabilization piece 626 has a notch 6261 or a gap 6262. On one hand, the notch 6261 or the gap 6262 can reduce the lateral restoring force between the image stabilization magnetic stabilization piece 626 and the image stabilization magnet 621, that is, reduce the magnetic attraction force perpendicular to the optical axis O between the image stabilization magnetic stabilization piece 626 and the image stabilization magnet 621, which hinders the realization of optical image stabilization. The magnetic attraction force perpendicular to the optical axis O between the image stabilization magnetic stabilization piece 626 and the image stabilization magnet 621 is a resistance to the realization of optical image stabilization, and can be called the lateral restoring force. The larger the lateral restoring force, the more detrimental it is to the realization of optical image stabilization. The causes and negative effects of the lateral restoring force are similar to those of the aforementioned longitudinal restoring force, and will not be elaborated further here. On the other hand, by forming the notch 6261 or the gap 6262 in the image stabilization magnetic stabilization plate 626, the image stabilization position sensing element 625 can be avoided, allowing the image stabilization position sensing element 625 to pass through the notch 6261 or the gap 6262 and be accommodated in the sensing element receiving groove 302, thereby reducing the longitudinal dimension of the motor 2 and thus facilitating the miniaturization of the motor 2 and the camera module. The sensing element receiving groove 302 is formed inside the magnetic stabilization plate receiving groove 303 and is further recessed downward relative to the magnetic stabilization plate receiving groove 303. It is worth mentioning that although the image stabilization magnetic stabilization plate 626 has the notch 6261 or the gap 6262, in the longitudinal direction, the image stabilization magnetic stabilization plate 626 still at least partially overlaps with the corresponding image stabilization magnet 621 to ensure that sufficient magnetic attraction is generated between the image stabilization magnetic stabilization plate 626 and the image stabilization magnet 621.

[0074] As attached Figure 3 Appendix Figure 14 and attached Figure 17As shown, the motor 2 also includes a shake-stabilizing support 627, which is disposed between the frame 4 and the base 3. The frame 4 and the base 3 clamp the shake-stabilizing support 627 under the magnetic attraction of the shake-stabilizing magnetic plate 626 and the shake-stabilizing magnet 621. The frame 4 is movably supported on the base 3 by the shake-stabilizing support 627. Preferably, the anti-shake support part 627 includes a first anti-shake support ball 6271, a second anti-shake support ball 6272, and a third anti-shake support ball 6273. The first anti-shake support ball 6271, the second anti-shake support ball 6272, and the third anti-shake support ball 6273 are respectively located at the three corners of the motor 2. The first anti-shake support ball 6271 is located at the corner of the motor 2 between the first side 201 and the third side 203. The second anti-shake support ball 6272 is located at the corner of the motor 2 between the third side 203 and the second side 202. The third anti-shake support ball 6273 is located at the corner of the motor 2 between the second side 202 and the fourth side 204. The stabilization coil 622 located on the third side 203 is between the first stabilization support ball 6271 and the second stabilization support ball 6272, and the two stabilization coils 622 located on the second side 202 are between the second stabilization support ball 6272 and the third stabilization support ball 6273. More preferably, the first stabilization support ball 6271, the second stabilization support ball 6272, and the third stabilization support ball 6273 have the same size.

[0075] Continue to refer to the appendix Figure 3 Appendix Figure 14 and attached Figure 17 To accommodate the first anti-shake support ball 6271, the second anti-shake support ball 6272, and the third anti-shake support ball 6273, the base 3 is provided with a first boss 304, a second boss 305, and a third boss 306 that protrude longitudinally upwards. The first anti-shake support ball 6271 is accommodated in the ball groove of the first boss 304, the second anti-shake support ball 6272 is accommodated in the ball groove of the second boss 305, and the third anti-shake support ball 6273 is accommodated in the ball groove of the third boss 306. Figure 15As shown, the bottom surface of the frame 4 forms a plane with the areas corresponding to the three ball grooves of the first boss 304, the second boss 305, and the third boss 306, eliminating the need for further constraint and restriction on the lateral movement of the frame 4 relative to the base 3 using the bottom surface of the frame 4. In some embodiments of the present invention, metal plates are provided on the bottom surface of the frame 4 with the areas corresponding to the three ball grooves of the first boss 304, the second boss 305, and the third boss 306 to enhance the strength of the contact surface and prevent the frame 4 from being damaged by the anti-vibration support balls, thus preventing the lateral movement of the frame 4 relative to the base 3 from being affected.

[0076] It is worth mentioning that the present invention only requires three image stabilization support balls: the first image stabilization support ball 6271, the second image stabilization support ball 6272, and the third image stabilization support ball 6273. This effectively and reliably supports the frame 4 on the base 3, eliminating the need for a fourth image stabilization support ball at the corner between the motor 2 and the fourth side 204 and the first side 201, and consequently eliminating the need for a fourth boss at the same corner. Thus, the first carrier-side guide groove 51 and the first frame-side guide groove 41 can be closer to the corner between the fourth side 204 and the first side 201, and they can also have sufficient longitudinal dimensions to ensure that the first accommodating space formed between them has sufficient longitudinal dimensions to accommodate a larger number of the first focusing support balls 6171. In other words, the first carrier-side guide groove 51 and the first frame-side guide groove 41 are located near the corner between the fourth side 204 and the first side 201, and the second carrier-side guide groove 52 and the second frame-side guide groove 42 are located near the corner between the first side 201 and the third side 203. This not only ensures that the first carrier-side guide groove 51 has sufficient longitudinal dimensions, but also reduces the lateral dimensions of the motor 2, which is beneficial for the miniaturization of the motor 2 and the camera module.

[0077] As attached Figure 2 Appendix Figure 3 and appendix Figure 9 To be continued Figure 17As shown, the image stabilization circuit board 624 is located only on the third side 203, the second side 202, and the fourth side 204 of the motor 2. The image stabilization circuit board 624 does not extend to the first side 201 of the motor 2, thus ensuring that the focusing magnet 611 and the image stabilization circuit board 624 do not overlap in the longitudinal direction; that is, the focusing magnet 611 and the image stabilization circuit board 624 are offset from each other by a certain distance in the longitudinal direction. The distance at which the focusing magnet 611 and the image stabilization circuit board 624 are offset from each other in the longitudinal direction is greater than the image stabilization travel of the motor 2, to prevent the focusing magnet 611 from impacting the image stabilization circuit board 624 when implementing optical image stabilization. The image stabilization travel refers to the maximum distance the frame 4 can move relative to the base 3 in the lateral direction. See attached diagram for details. Figure 2 Since the focusing magnet 611 and the image stabilization circuit board 624 do not overlap in the longitudinal direction, the focusing magnet 611 can be sunken as much as possible to be closer to the base 3 without being interfered with by the image stabilization circuit board 624. This allows the carrier 5 and the focusing magnet 611 to be closer to the base 3 as a whole, reducing the height of the carrier 5 in the longitudinal direction and thus reducing the longitudinal dimension of the motor 2, which is beneficial for the miniaturization of the motor 2 and the camera module. It is worth mentioning that when implementing the optical focusing function, the focusing magnet 611 can move downwards along the longitudinal direction with the carrier 5 until the bottom surface of the focusing magnet 611 is lower than the top surface of the image stabilization circuit board 624, thereby maximizing the sunken placement of the focusing magnet 611 to reduce the longitudinal dimension of the motor 2. (See attached image) Figure 3 Appendix Figure 14 Appendix Figure 16 and attached Figure 17 As shown, the image stabilization circuit board 624 is generally U-shaped to meet the above requirements.

[0078] As attached Figure 10As shown, since the first carrier-side guide groove 51 is formed on the outer side of the carrier 5 located on the first side 201, and the image stabilization circuit board 624 does not extend to the first side 201 of the motor 2, the first carrier-side guide groove 51 and the image stabilization circuit board 624 do not overlap in the longitudinal direction, that is, the first carrier-side guide groove 51 and the image stabilization circuit board 624 are offset from each other by a certain distance in the longitudinal direction. The distance between the first carrier-side guide groove 51 and the image stabilization circuit board 624 in the longitudinal direction is greater than the image stabilization stroke of the motor 2, so as to prevent the carrier 5 from hitting the image stabilization circuit board 624 when realizing the optical image stabilization function. In this way, in order to ensure that the first carrier-side guide groove 51 has sufficient longitudinal dimensions, the first carrier-side guide groove 51 can extend downward as much as possible, that is, extend towards the base 3, which helps to reduce the longitudinal dimensions of the carrier 5, thereby reducing the longitudinal dimensions of the motor 2, which is beneficial to the miniaturization of the motor 2 and the camera module.

[0079] Further reference attached Figure 9 To be continued Figure 12 In order to reduce the longitudinal dimension of the motor 2, the carrier 5 is positioned as close as possible to the base 3, and the anti-shake circuit board 624 is avoided by a first clearance groove 53 formed at the bottom of the carrier 5 in the longitudinal direction.

[0080] As attached Figure 11 To be continued Figure 13 As shown, the carrier 5 also has a second clearance groove 54, which is formed on one side of the carrier 5 located on the third side 203, and is located at the bottom of the carrier 5 in the longitudinal direction. The second clearance groove 54 is used to avoid the image stabilization coil 622 located on the third side 203, thereby reducing the lateral and longitudinal dimensions of the motor 2, which is beneficial to the miniaturization of the motor 2 and the camera module. Further, according to the foregoing, the second carrier side guide groove 52 does not extend to the bottom of the carrier 5 in the longitudinal direction. In this way, the second clearance groove 54 can extend below the second carrier side guide groove 52 to avoid the first boss 304, thereby making the carrier 5 and the base 3 more compact, and further reducing the lateral and longitudinal dimensions of the motor 2.

[0081] As attached Figure 18As shown, since the focusing magnet 611 and the focusing coil 612 are located on the first side 201 of the motor 2, and the image stabilization magnet 621 and the image stabilization coil 622 are located on the third side 203 and the second side 202 of the motor 2, in order to make the various components of the motor 2 more compact and to reasonably avoid the focusing magnet 611, the focusing coil 612, the image stabilization magnet 621, and the image stabilization coil 622, the optical lens 10 is offset from the motor 2. Specifically, the center O1 of the lens mounting hole 50 of the carrier 5 for supporting the optical lens 10 is offset towards the fourth side 204 relative to the center O2 of the motor 2, wherein the optical axis O passes through the center O1 of the lens mounting hole 50, and the center O2 of the motor 2 is the intersection of the diagonals connected diagonally at the four corners of the motor 2.
