Therefore, the above terms should not be understood as limiting the present invention.

[0044] Reference is made to the attached drawings of the present invention. Figure 1 To Attachment Fig.18 , a camera module and its motor according to an embodiment of the present invention are explained. The camera module includes an optical lens 10, a photosensitive component 11 and a motor 2, wherein the motor 2 is arranged on the photosensitive component 11, and the optical lens 10 is maintained on the photosensitive path of the photosensitive component 11 through the motor 2, and the photosensitive component 11 is used to receive the light emitted by the optical lens 10 for imaging to obtain an image of the subject. The motor 2 is suitable for driving the optical lens 10 to move to achieve optical performance adjustment, for example, for achieving optical focus, optical image stabilization and other functions. The optical lens 10 has an optical axis O, and the photosensitive component 11 is arranged relative to the optical lens 10 along the direction of the optical axis O. For the convenience of subsequent description, the direction parallel to the optical axis O is the longitudinal direction, and the direction perpendicular to the optical axis O is the transverse direction.

[0045] 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, wherein the photosensitive chip 112 is used to receive the light reflected by the object collected by the optical lens 10 for imaging, and the photosensitive chip 112 is electrically connected to the electronic device through the imaging circuit board 111. The electronic component 113 can be one or more of passive electronic devices such as resistors and capacitors, and can also be one or more of active electronic devices such as driver chips and storage chips.

[0046] In some embodiments of the present invention, the photosensitive component 11 also includes a filter element 114, which is maintained on the photosensitive path of the photosensitive chip 112, so as to filter the light incident on the photosensitive chip 112 and filter out light that is not necessary for imaging (for example, infrared light, etc.) in the incident light.

[0047] In some embodiments of the present invention, the photosensitive component 11 further includes a bracket 115, the filter element 114 is mounted on the bracket 115, and the bracket 115 is fixed to the imaging circuit board 111, so that the filter element 114 is held on the photosensitive path of the photosensitive chip 112 through the bracket 115. Accordingly, the motor 2 can be fixed to the photosensitive component 11 in a manner of being fixed to the bracket 115. Optionally, the motor 2 can also be fixed to the photosensitive component 11 in a manner of being fixed to the imaging circuit board 111. At this time, if the photosensitive component 11 is still provided with the bracket 115, the bracket 115 is retracted compared to the edge of the imaging circuit board 111 to avoid the motor 2, thereby providing a spatial position for fixing the motor 2.

[0048] Understandable, Figure 2 The specific structure of the photosensitive component 11 shown is only for illustration, so as to facilitate the explanation of the overall scheme of the present invention, and 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 mode of the present invention and should be covered by the protection scope of the present invention.

[0049] As attached Figure 1 To Attachment Figure 3 As shown, the camera module also includes a cover 12, which is covered on the motor 2, and the cover 12 is provided with a window 120, so that the optical lens 10 is exposed through the window 120, so that the optical lens 10 can receive light reflected by the subject.

[0050] As attached Figure 2 To Attachment Fig.18As shown, the motor 2 includes a base 3, a frame 4, a carrier 5 and a driving assembly 6, wherein the carrier 5 is used to carry the optical lens 10 of the camera module, the carrier 5 is movably arranged in the frame 4, and the driving assembly 6 is arranged to drive the carrier 5 to move relative to the frame 4 along the longitudinal direction (i.e., the direction parallel to the optical axis O), so that the carrier 5 and the optical lens 10 fixed to the carrier 5 can move along the longitudinal direction under the drive of the driving assembly 6 to achieve the optical focus function of the camera module; the frame 4 is movably arranged on the base 3, and the driving assembly 6 is also arranged to drive the frame 4 to move relative to the base 3 along the transverse direction (i.e., the direction perpendicular to the optical axis O), so that the frame 4 and the carrier 5 arranged on the frame 4 can move along the transverse direction under the drive of the driving assembly 6, and then the optical lens 10 fixed to the carrier 5 can move along the transverse direction under the drive of the driving assembly 6 to achieve the optical image stabilization function of the camera module.

[0051] As attached Figure 2 , Attachment Figure 3 and attached Figure 6 As shown, the driving component 6 includes a focus driving component 61, and the focus driving component 61 is used to drive the carrier 5 to move relative to the frame 4 along the longitudinal direction, wherein the focus driving component 61 includes a focus magnet 611 and a focus coil 612, and the focus magnet 611 and the focus coil 612 are arranged opposite to each other, wherein one of the focus magnet 611 and the focus coil 612 is arranged on the frame 4, and the other is arranged on the carrier 5. In some embodiments of the present invention, the focus magnet 611 is arranged on the carrier 5, and the focus coil 612 is arranged on the frame 4. Optionally, in other embodiments of the present invention, the focus magnet 611 is arranged on the frame 4, and the focus coil 612 is arranged on the carrier 5.

[0052] As attached Figure 2 and attached Figure 6 As shown, the focus magnet 611 and the focus coil 612 are both located on the first side 201 of the motor 2, wherein the focus magnet 611 is disposed on the side of the carrier 5 located on the first side 201, and the focus coil 612 is disposed on the side of the frame 4 located on the first side 201, so that the focus magnet 611 and the focus coil 612 are disposed opposite to each other. In particular, the focus coil 612 is disposed longitudinally, that is, the center line of the coil hole of the focus coil 612 is perpendicular to the optical axis O, and the focus coil 612 and the focus magnet 611 are disposed opposite to each other in a direction perpendicular to the longitudinal direction.

[0053] Continue to refer to the attached Figure 2 and attached Figure 6 The motor 2 further includes a focus magnetic conductive sheet 613, which is used to enhance the magnetic field strength of the focus magnet 611, wherein the focus magnetic conductive sheet 613 is disposed on a side of the focus magnet 611 away from the focus coil 612. Preferably, the focus magnet 611 is disposed on one side of the carrier 5 in a manner of being fixed to the focus magnetic conductive sheet 613, for example, the focus magnetic conductive sheet 613 is first embedded in the carrier 5, and then the focus magnet 611 is fixed to the focus magnetic conductive sheet 613.

[0054] As attached Figure 2 To Attachment Figure 6 As shown, the motor 2 also includes a focusing circuit board 614, a 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, and the focusing coil 612 is fixed to the frame fixing portion 6141 of the focusing circuit board 614 and is electrically connected to the focusing circuit board 614, wherein the focusing coil 612 is fixed to the side of the frame fixing portion 6141 close to the focusing magnet 611. The frame 4 is provided with a frame opening 400, and the frame opening 400 is formed on the side of the frame 4 on the first side 201, and the focusing coil 612 is at least partially accommodated in the frame opening 400. In other words, the focusing coil 612 is arranged on the side of the frame 4 on the first side 201 in a manner of being fixed to the frame fixing portion 6141 of the focusing circuit board 614. As Figure 3 As shown, the frame 4 is provided with a frame positioning protrusion 401, and the frame positioning protrusion 401 protrudes outward from the outer side surface of the frame 4 located on the first side 201, and the focusing circuit board 614 is provided with a frame positioning hole 6140 located on the frame fixing portion 6141, and 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 fixing the frame fixing portion 6141 of the focusing circuit board 614 to the outer side of the frame 4 located on one side of the first side 201, which is beneficial to improving accuracy and reliability.

[0055] As attached Figure 2 and attached Figure 6As shown, the motor 2 further includes a focus position sensing element 615, which is fixed to the focus circuit board 614 and electrically connected to the focus circuit board 614, and the focus position sensing element 615 is arranged opposite to the focus magnet 611 and is used to sense the magnetic field change of the focus magnet 611 to obtain the position change information of the focus magnet 611 and the carrier 5 in the longitudinal direction. Preferably, the focus position sensing element 615 is arranged in the coil hole of the focus coil 612, and the focus position sensing element 615 is fixed to the frame fixing portion 6141 of the focus circuit board 614.

[0056] As attached Figure 2 To Attachment Figure 4 And attached Figure 6 As shown, the motor 2 further includes a focusing magnetic sheet 616, which is disposed on a side of the focusing coil 612 away from the focusing magnet 611, and is disposed on a side of the frame 4 located on the first side 201. It can be understood that the carrier 5 is supported in the frame 4 by the magnetic attraction between the focusing magnetic sheet 616 and the focusing magnet 611. Preferably, the focusing magnetic sheet 616 is fixed (for example, fixed by glue bonding) on ​​a side of the frame fixing portion 6141 of the focusing circuit board 614 away from the focusing magnet 611, so that the focusing magnetic sheet 616 is disposed on a side of the frame 4 located on the first side 201 in a manner of being fixed to the frame fixing portion 6141 of the focusing circuit board 614. The focusing magnetic sheet 616 is provided with a positioning hole 6160, and the positioning hole 6160 matches and corresponds to the frame positioning protrusion 401, so that the frame positioning protrusion 401 can further penetrate into or even pass through the positioning hole 6160 after passing through the frame positioning hole 6140, thereby facilitating fixing the focusing magnetic sheet 616 to the side of the frame fixing portion 6141 of the focusing circuit board 614 away from the focusing magnet 611, which is beneficial to improving accuracy and reliability.

[0057] As attached Figure 3 , Attachment Figure 4 , Attachment Figure 6 and attached Figure 7As shown, the focusing magnetic sheet 616 has at least one hollow hole 6161, which extends along the longitudinal direction and is in the shape of a long strip. By setting the hollow hole 6161, the longitudinal restoring force between the focusing magnetic sheet 616 and the focusing magnet 611 can be reduced, that is, the magnetic component force between the focusing magnetic sheet 616 and the focusing magnet 611 parallel to the direction of the optical axis O, which hinders the realization of the optical focusing function, can be reduced. It can be understood that since the focusing magnet 611 moves in the longitudinal direction with the carrier 5, the center of the focusing magnet 611 and the center of the focusing magnetic sheet 616 cannot always be aligned, and thus the magnetic attraction force between the focusing magnetic sheet 616 and the focusing magnet 611 cannot always be perpendicular to the optical axis O. Therefore, the magnetic attraction component between the focusing magnetic sheet 616 and the focusing magnet 611 parallel to the direction of the optical axis O is a resistance to achieving the optical focusing function, which can be called a longitudinal restoring force. The larger the longitudinal restoring force, the more unfavorable it is for achieving the optical focusing function.

[0058] As attached Figure 7 As shown, the hollow hole 6161 is in the shape of an elongated strip, which means that the height H of the hollow hole 6161 is greater than the width W of the hollow hole 6161, wherein the height direction of the hollow hole 6161 is parallel to the optical axis O, and the width direction of the hollow hole 6161 is perpendicular to the optical axis O. By providing the elongated hollow hole 6161, the longitudinal restoring force between the focus magnetic suction sheet 616 and the focus magnet 611 can be effectively reduced, so as to enhance the performance of the motor 2 and the camera module.

[0059] Continue to refer to the attached Figure 7 Preferably, the focusing magnetic sheet 616 is provided with a plurality of hollow holes 6161, and the plurality of hollow holes 6161 are arranged at intervals from each other. The plurality of hollow holes 6161 together define a coverage width range R. Figure 7 In the direction in which the focusing magnetic sheet 616 and the focusing magnet 611 are relatively set, the coverage width range R completely covers the width range r of the focusing magnet 611, so that the longitudinal restoring force is greatly reduced. It has been verified through actual tests that by setting a plurality of the hollow holes 6161, the ratio of the longitudinal restoring force to the magnetic component force along the relative setting direction of the focusing magnetic sheet 616 and the focusing magnet 611 is less than 1:100. In a specific example, the longitudinal restoring force is 0.5mN, while the magnetic component force along the relative setting direction of the focusing magnetic sheet 616 and the focusing magnet 611 is 80 mN, and the ratio of the two is only 1:160, which greatly reduces the longitudinal restoring force, thereby greatly weakening the hindrance of the longitudinal restoring force to the realization of the optical focusing function.

[0060] It is worth mentioning that in the initial state of the motor 2, in the longitudinal direction (i.e., height direction), the center of the focusing magnet 611 and the center of the hollow hole 6161 are at the same height, so that the longitudinal restoring force applied to the carrier 5 when moving upward or downward is similar, thereby facilitating the driving control of the motor 2.

[0061] As attached Figure 3 And attached Figure 8 To Attachment Fig.13 As shown, the motor 2 further includes a focus support portion 617, which is disposed between the carrier 5 and the frame 4. The carrier 5 and the frame 4 clamp the focus support portion 617 under the magnetic attraction of the focus magnetic sheet 616 and the focus magnet 611, and the carrier 5 is movably supported in the frame 4 through the focus support portion 617. The carrier 5 is provided with a first carrier side guide groove 51 and a second carrier side guide groove 52, both of which are formed on the outer side of the carrier 5 on one side of the first side 201, and the first carrier side guide groove 51 and the second carrier side guide groove 52 are respectively located on both sides of the focus magnet 611. The frame 4 is provided with a first frame side guide groove 41 and a second frame side guide groove 42, both of which are formed on the inner side of the frame 4 on the side of the first side 201, and the first frame side guide groove 41 and the second frame side guide groove 42 are respectively located on both sides of the focus 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 are all extended along the longitudinal direction, the first carrier side guide groove 51 and the first frame side guide groove 41 are arranged relative to each other to form a first accommodation space located between the first carrier side guide groove 51 and the first frame side guide groove 41, the second carrier side guide groove 52 and the second frame side guide groove 42 are arranged relative to each other to form a second accommodation space located between the second carrier side guide groove 52 and the second frame side guide groove 42, and the focus support portion 617 is accommodated in the first accommodation space and the second accommodation space.

[0062] As attached Figure 3 And attached Figure 8 To Attachment Fig.12As shown, in some embodiments of the present invention, the focus support portion 617 includes at least two first focus support balls 6171 and at least one second focus support ball 6172. The first focus support ball 6171 is arranged between the first carrier side guide groove 51 and the first frame side guide groove 41, and is accommodated in the first accommodation space, and the first focus support ball 6171 can roll in the first accommodation space and / or slide to a certain extent along the longitudinal direction. The second focus support ball 6172 is arranged between the second carrier side guide groove 52 and the second frame side guide groove 42, and is accommodated in the second accommodation space, and the second focus support ball 6172 can roll in the second accommodation space and / or slide to a certain extent along the longitudinal direction. The number of the first focus support balls 6171 is greater than the number of the second focus support balls 6172, so that the first focus support balls 6171, the first carrier side guide grooves 51 and the first frame side guide grooves 41 play a major guiding role in the longitudinal movement of the carrier 5, while the second focus support balls 6172, the second carrier side guide grooves 52 and the second frame side guide grooves 42 play an auxiliary guiding role in the longitudinal movement of the carrier 5. Preferably, the size of the first focus support balls 6171 is the same as that of the second focus support balls 6172.

[0063] Therefore, the longitudinal dimension of the second accommodation space required by the second focus support ball 6172 can be smaller than the longitudinal dimension of the first accommodation space required by the first focus support ball 6171. Further considering the positional relationship and matching relationship between the various components of the motor 2, and the creative avoidance design that the carrier 5 can make, the present invention creatively proposes an implementation method of reducing the longitudinal dimension of the second carrier side guide groove 52. Figure 3 , Attachment Fig. 9 , Attachment Fig.11 and attached Fig.12As shown, the second carrier side guide groove 52 has a lower groove wall 521, and the lower groove wall 521 is located in the middle position of the carrier 5 in the longitudinal direction, so that the second carrier side guide groove 52 extends from the top position of the carrier 5 in the longitudinal direction only to the lower groove wall 521, while the first carrier side guide groove 51 extends from the top position of the carrier 5 in the longitudinal direction to the bottom position. In this way, 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 position of the carrier 5 in the longitudinal direction, so that the necessary avoidance structure can be provided below the second carrier side guide groove 52, which will be further expanded in the subsequent description. It can be understood that the lower groove wall 521 can prevent the second focus support ball 6172 from falling off from the bottom, and play a role in limiting and preventing falling off. Accordingly, as shown in the attached Fig.10 As shown, the first frame side guide groove 41 has a groove bottom wall 411, and the groove bottom wall 411 is located at the bottom position of the frame 4 in the longitudinal direction. The groove bottom wall 411 can prevent the first focus support ball 6171 from falling off from below, and plays a role of limiting and preventing falling off. 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.

[0064] As attached Figure 3 And attached Fig. 9 To Attachment Fig.12As shown, the motor 2 further includes a stopper 618, wherein the stopper 618 is fixed to the carrier 5, and the stopper 618 includes a first stopper arm 6181 and a second stopper arm 6182. The first stopper arm 6181 extends to the upper side of the first carrier side guide groove 51 in the longitudinal direction, and does not extend into the first carrier side guide groove 51, thereby preventing the first focus support ball 6171 from escaping from the upper side while providing a sufficient longitudinal dimension for the first accommodation space. The second stopper arm 6182 extends into the second carrier side guide groove 52 to further limit the movable space of the second focus support ball 6172 and prevent the second focus support ball 6172 from escaping from the upper side. It can be understood that by providing the stopper 618, the assembly of the first focus support ball 6171 and the second focus support ball 6172 can be made easier. Specifically, after the carrier 5 and the frame 4 are aligned and assembled, the first focus support ball 6171 can be placed between the first carrier side guide groove 51 and the first frame side guide groove 41 from above, and the second focus support ball 6172 can also be placed between the second carrier side guide groove 52 and the second frame side guide groove 42 from above, and then the stopper 618 is fixed to the carrier 5, so that the first focus support ball 6171 and the second focus support ball 6172 cannot fall out from above.

[0065] As attached Fig.13 As shown, in some optional embodiments of the present invention, the focus support portion 617 may no longer be implemented as a focus support ball, but may be implemented as two focus support guide rods, one of which is disposed between the first carrier side guide groove 51 and the first frame side guide groove 41, and the other is disposed between the second carrier side guide groove 52 and the second frame side guide groove 42. The focus support guide rods may be fixed to the carrier 5 or the frame 4, so that the stopper 618 is no longer required. Preferably, the longitudinal dimension of the focus 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 focus support guide rod disposed between the first carrier side guide groove 51 and the first frame side guide groove 41, so that the second carrier side guide groove 52 still has the lower groove wall 521 located in the middle of the carrier 5 in the longitudinal direction, so that a necessary avoidance structure can be disposed below the second carrier side guide groove 52.

[0066] As attached Figure 3 To Attachment Figure 5As shown, the focusing circuit board 614 must be electrically connected to the conductive circuit 31 embedded in the base 3 while being fixed to the frame 4, that is, the focusing circuit board 614 should also be provided with 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 fixed to the frame 4 and the base 3 at the same time. Since the frame 4 moves relative to the base 3 along 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, and will inevitably generate additional resistance. In order to reduce the resistance brought 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 sides 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 caused by the focusing circuit board 614.

[0067] Continue to refer to the attached Figure 3 To Attachment 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 the two. The connecting part 6143 is preferably a flexible circuit board. The frame fixing portion 6141 is fixed to the outer side of the frame 4 on one side of the first side 201, the base fixing portion 6142 is fixed to the outer side of the base 3 on one side of the second side 202, and the connecting portion 6143 extends in a bent manner between the frame fixing portion 6141 and the base fixing portion 6142, wherein the connecting portion 6143 includes a first connecting band 6144 and a second connecting band 6145, the two ends of the first connecting band 6144 are electrically connected to the frame fixing portion 6141 and the second connecting band 6145 respectively, and the two ends of the second connecting band 6145 are electrically connected to the base fixing portion 6142 and the first connecting band 6144 respectively. The first connecting belt 6144 is inclined relative to the outer side surface of the frame 4 located on the third side 203 of the motor 2, and the second connecting belt 6145 is inclined relative to the outer side surface of the frame 4 located on the second side 202 of the motor 2, and the angle between the first connecting belt 6144 and the second connecting belt 6145 is an obtuse angle, so as to better reduce the resistance brought by the focusing circuit board 614, wherein the third side 203 of the motor 2 is adjacent to the first side 201 and the second side 202. The frame 4 is provided with a first accommodating groove 43 extending obliquely at the top of the third side 203, and a second accommodating groove 44 extending obliquely is provided between the frame 4 and the carrier 5, and the second accommodating groove 44 is formed between the frame 4 and the carrier 5 at the top of the second side 202, wherein the first connecting belt 6144 is at least partially accommodated in the first accommodating groove 43, and the second connecting belt 6145 is at least partially accommodated in the second accommodating groove 44, so that the frame 4 can shield and protect the first connecting belt 6144 and the second connecting belt 6145 to a certain extent on the outside, so as to reduce the risk of the first connecting belt 6144 and the second connecting belt 6145 being damaged on the outside, thereby enhancing the reliability of the motor 2, which is beneficial to prolonging the service life of the motor 2 and the camera module. It can be understood that the first connecting belt 6144 and the second connecting belt 6145 are both inclined, and the angle between the two is an obtuse angle, which can greatly reduce the obstruction of the focusing circuit board 614 to the movement of the frame 4 relative to the base 3 along the lateral direction, and is more conducive to reducing the resistance brought by the focusing circuit board 614.

[0068] Continue to refer to the attached Figure 3 To Attachment Figure 5, the motor 2 also includes two shaping parts 6146, which are used to maintain the bending shape of the bending part of the focusing circuit board 614, wherein one of the shaping parts 6146 is arranged at the bending part where the first connecting belt 6144 and the frame fixing part 6141 are connected, and is located at the corner of the motor 2 between the first side 201 and the third side 203, and the other shaping part 6146 is arranged at the bending part where the second connecting belt 6145 and the first connecting belt 6144 are connected, and is located at the corner of the motor 2 between the third side 203 and the second side 202. It is worth mentioning that the shaping part 6146 can be made of materials such as metal or plastic, so that it can maintain its own bending shape, and then be used to maintain the bending shape of the bending part of the focusing circuit board 614. The shaping part 6146 is fixed by directly attaching to the bending part of the focusing circuit board 614, such as bonding to the bending part of the focusing circuit board 614. Preferably, the shaping portion 6146 is in a curved frame shape, so as to reduce the weight of the shaping portion 6146, so as to avoid excessive resistance to the movement of the frame 4 relative to the base 3 along the lateral direction due to the provision of the shaping portion 6146. It is also worth mentioning that the shaping portion 6146 is provided on the outside of the curved portion of the focusing circuit board 614, so as to provide a certain degree of protection to the curved portion of the focusing circuit board 614 on the outside to prevent it from being damaged by the outside.

[0069] As attached Figure 5 As shown, the base 3 is provided with at least one base positioning protrusion 301, and the base positioning protrusion 301 protrudes outward from the outer side surface of the base 3 located on the second side 202, and the focusing circuit board 614 is provided with at least one base positioning hole 6147 located on the base fixing portion 6142, and 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 fixing the base fixing portion 6142 of the focusing circuit board 614 to the outer side of one 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, and the focusing circuit board connection end 311 is exposed on one side of the base 3 located on the second side 202, so as to facilitate welding connection with the concave soldering pad of the base fixing portion 6142 of the focusing circuit board 614, thereby realizing electrical connection between the conductive circuit 31 and the focusing circuit board 614.

[0070] As attached Figure 2 , Attachment Figure 3 , Attachment Figure 6 And attached Fig.14 To Attachment Fig.17As shown, the driving assembly 6 also includes an anti-shake driving assembly 62, and the anti-shake driving assembly 62 is used to drive the frame 4 to move relative to the base 3 along the lateral direction, wherein the anti-shake driving assembly 62 is arranged on other sides of the motor 2 where the focus driving assembly 61 is not arranged, such as the second side 202, the third side 203 and / or the fourth side 204 of the motor 2. In other words, the anti-shake driving assembly 62 and the focus driving assembly 61 are arranged on different sides of the motor 2, which can avoid the anti-shake driving assembly 62 and the focus driving assembly 61 from overlapping each other in the longitudinal direction, and the longitudinal size of the motor 2 is reduced, which is conducive to the miniaturization of the motor 2 and the camera module. Moreover, since the anti-shake driving assembly 62 and the focus driving assembly 61 are arranged on different sides of the motor 2, there will be no mutual magnetic interference between the anti-shake driving assembly 62 and the focus driving assembly 61, which can enhance the performance and reliability of the motor 2 and the camera module. The four sides of the motor 2 are respectively the first side 201, the second side 202, the third side 203 and the fourth side 204, wherein the first side 201 and the second side 202 are opposite to each other, the third side 203 and the fourth side 204 are opposite to each other, the third side 203 is adjacent to the first side 201 and the second side 202, and the fourth side 204 is also adjacent to the first side 201 and the second side 202. The anti-shake driving component 62 includes at least one anti-shake magnet 621 and at least one anti-shake coil 622, wherein the anti-shake magnet 621 and the corresponding anti-shake coil 622 are arranged opposite to each other, wherein one of the anti-shake magnet 621 and the anti-shake coil 622 is arranged on the frame 4, and the other is arranged on the base 3. In some embodiments of the present invention, the anti-shake magnet 621 is arranged on the frame 4, and the anti-shake coil 622 is arranged on the base 3. Optionally, in some 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 .

[0071] As attached Figure 3 , Attachment Fig.14 and attached Fig.15As shown, the anti-shake magnet 621 is arranged on the frame 4 and is located at the bottom of the frame 4 in the longitudinal direction, and the anti-shake coil 622 is arranged on the base 3 and is located at the top of the base 3 in the longitudinal direction, so that the anti-shake magnet 621 and the anti-shake coil 622 are arranged relative to each other. In particular, the anti-shake coil 622 is arranged horizontally, that is, the center line of the coil hole of the anti-shake coil 622 is parallel to the optical axis O, and the anti-shake coil 622 and the anti-shake magnet 621 are arranged relative to each other along the longitudinal direction. It can be understood that the arrangement of the anti-shake coil 622 being arranged horizontally at the top of the base 3 in the longitudinal direction is conducive to reducing the longitudinal size of the motor 2 compared to the arrangement of the anti-shake coil 622 being arranged longitudinally at the top of the base 3 in the longitudinal direction, thereby facilitating the miniaturization of the motor 2 and the camera module. It can also be understood that the arrangement of the anti-shake coil 622 located at the lower side of the frame 4 in the longitudinal direction is conducive to reducing the lateral size of the motor 2, thereby facilitating the miniaturization of the motor 2 and the camera module, compared to the arrangement of the anti-shake coil 622 located at the outer side of the frame 4. Therefore, the arrangement of the anti-shake drive assembly 62 and the focus drive assembly 61 provided by the present invention being arranged on different sides of the motor 2, and the anti-shake coil 622 being arranged transversely at the top of the base 3 in the longitudinal direction is not only conducive to reducing the longitudinal size of the motor 2, but also conducive to reducing the lateral size of the motor 2.

[0072] Continue to refer to the attached Figure 3 , Attachment Fig.14 and attached Fig.15 Preferably, the anti-shake drive component 62 includes three anti-shake magnets 621 and three anti-shake coils 622, wherein one anti-shake magnet 621 is arranged at the bottom of the frame 4 on the side of the third side 203, and a corresponding anti-shake coil 622 is arranged at the top of the base 3 on the side of the third side 203, and the other two anti-shake magnets 621 are both arranged at the bottom of the frame 4 on the side of the second side 202, and the other two anti-shake coils 622 are both arranged at the top of the base 3 on the side of the second side 202.

[0073] As attached Figure 2 , Attachment Figure 6 and attached Fig.15As shown, the motor 2 further includes at least one anti-shake magnetic conductive sheet 623, and the anti-shake magnetic conductive sheet 623 is used to enhance the magnetic field strength of the corresponding anti-shake magnet 621, wherein the anti-shake magnetic conductive sheet 623 is arranged 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 arranged at the bottom of the frame 4 in a manner of being fixed to the corresponding anti-shake magnetic conductive sheet 623, for example, the anti-shake magnetic conductive 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 conductive sheet 623.

[0074] As attached Fig.14 As shown, the motor 2 further includes an anti-shake circuit board 624, the anti-shake circuit board 624 is fixed to the top surface of the base 3 in the longitudinal direction, and the anti-shake coil 622 is fixed to the top surface of the anti-shake circuit board 624 in the longitudinal direction and is electrically connected to the anti-shake circuit board 624, so that the anti-shake coil 622 is arranged at the top of the base 3 in the longitudinal direction. In other words, the anti-shake coil 622 is arranged at the top of the base 3 in a manner of being fixed to the anti-shake circuit board 624.

[0075] Continue to refer to the attached Fig.14 Preferably, the anti-shake circuit board 624 is provided with a plurality of pads on the top surface in the longitudinal direction, and the anti-shake coil 622 can lead out electrical connection wires (electrical connection wires are not shown in the figure) to be welded and connected with corresponding pads, so as to realize electrical connection between the anti-shake coil 622 and the anti-shake circuit board 624. It can be understood that Fig.14 The position of the pad for electrically connecting to the anti-shake coil 622 is shown for illustration only. In other embodiments of the present invention, the position of the pad may be adaptively adjusted according to actual needs.

[0076] As attached Fig.14 , Attachment Fig.16 and attached Fig.17 As shown, the conductive circuit 31 is further provided with an anti-shake circuit board connection end 312, and the anti-shake circuit board connection end 312 is exposed on the top surface of the base 3, so as to be welded and connected with the pad provided on the bottom surface of the anti-shake circuit board 624, thereby realizing the electrical connection between the conductive circuit 31 and the anti-shake circuit board 624. Preferably, the conductive circuit 31 is provided with four anti-shake circuit board connection ends 312 exposed on the top surface of the base 3, and correspondingly, the bottom surface of the anti-shake circuit board 624 is provided with four pads for electrical connection with the conductive circuit 31.

[0077] As attached Figure 4 , Attachment Figure 5 , Attachment Fig.14 and attached Fig.16As shown, the conductive circuit 31 is also provided with a photosensitive component connection end 313, which is exposed on the base 3 and is used to be electrically connected to the photosensitive component 11 of the camera module. Preferably, the photosensitive component connection end 313 is exposed on one side of the base 3 located on the third side 203.

[0078] As attached Fig.16 As shown, the motor 2 further includes at least one anti-shake position sensing element 625, which is fixed to the anti-shake circuit board 624 and electrically connected to the anti-shake circuit board 624, and is used to sense the magnetic field change of the corresponding anti-shake magnet 621 to obtain the 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 arranged 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, and the anti-shake position sensing element 625 is arranged directly below the corresponding anti-shake coil 622, so as to correspond to the corresponding anti-shake magnet 621. Accordingly, in order to accommodate the anti-shake position sensing element 625, the base 3 is provided with at least one sensing element accommodating groove 302, and the sensing element accommodating groove 302 is formed by the top surface of the base 3 being recessed downward. 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 accommodating grooves 302, and the anti-shake position sensing element 625 is accommodated in the corresponding sensing element accommodating grooves 302. It can be understood that the method of arranging the anti-shake position sensing element 625 on the bottom surface of the anti-shake circuit board 624 is helpful to reduce the lateral size of the motor 2 compared to the method of arranging the anti-shake position sensing element 625 on the top surface of the anti-shake circuit board 624, thereby facilitating the miniaturization of the motor 2 and the camera module. It can also be understood that by forming the sensing element accommodating groove 302 by recessing downward on the top surface of the base 3 to accommodate the anti-shake position sensing element 625, it is helpful to reduce the longitudinal size of the motor 2, thereby facilitating the miniaturization of the motor 2 and the camera module.

[0079] As attached Fig.17As shown, the motor 2 further includes at least one anti-shake magnetic sheet 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 sheet 626 and the corresponding anti-shake magnet 621. The anti-shake magnetic sheet 626 can be directly fixed to the base 3 by bonding or insert molding, or it can be indirectly fixed to the base 3 by fixing it to the anti-shake circuit board 624. Preferably, the anti-shake magnetic sheet 626 is directly fixed to the base 3. This method of directly fixing it to the base 3 helps to reduce the complexity of the process and reduce 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 sheet accommodating groove 303, and the magnetic sheet accommodating groove 303 is formed by the top surface of the base 3 being recessed downward, and the anti-shake magnetic sheet 626 is disposed in the magnetic sheet accommodating groove 303. Preferably, the motor 2 includes two anti-shake magnetic sheets 626, one of which is located on the third side 203 of the motor 2, corresponding to one of the anti-shake magnets 621 located on the third side 203, and the other anti-shake magnetic sheet 626 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.

[0080] It is worth mentioning that accommodating the anti-shake magnetic sheet 626 by providing the magnetic sheet accommodating groove 303, rather than embedding the anti-shake magnetic sheet 626 in the base 3 by insert molding, helps to reduce the lateral size of the motor 2. It should be understood that if the anti-shake magnetic sheet 626 is fixed by insert molding, the base 3 needs to wrap the side of the anti-shake magnetic sheet 626, which will increase the lateral size of the base 3.

[0081] Continue to refer to the attached Fig.17, the anti-shake magnetic sheet 626 has a missing hole 6261 or a notch 6262. On the one hand, the missing hole 6261 or the notch 6262 can reduce the lateral restoring force between the anti-shake magnetic sheet 626 and the anti-shake magnet 621, that is, reduce the magnetic component force between the anti-shake magnetic sheet 626 and the anti-shake magnet 621 that is perpendicular to the direction of the optical axis O and hinders the realization of the optical image stabilization function. The magnetic component force between the anti-shake magnetic sheet 626 and the anti-shake magnet 621 that is perpendicular to the direction of the optical axis O is the resistance to the realization of the optical image stabilization function, which can be called the lateral restoring force. The larger the lateral restoring force, the more unfavorable it is for the realization of the optical image stabilization function. 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 on here. On the other hand, the anti-shake position sensing element 625 can be avoided by the notch 6261 or the notch 6262 formed in the anti-shake magnetic sheet 626, so as to allow the anti-shake position sensing element 625 to pass through the notch 6261 or the notch 6262 and be accommodated in the sensing element accommodating groove 302, so as to reduce the longitudinal dimension of the motor 2, thereby facilitating the miniaturization of the motor 2 and the camera module. The sensing element accommodating groove 302 is formed on the inner side of the magnetic sheet accommodating groove 303, and is further recessed downward relative to the magnetic sheet accommodating groove 303. It is worth mentioning that although the anti-shake magnetic sheet 626 is provided with the notch 6261 or the notch 6262, in the longitudinal direction, the anti-shake magnetic sheet 626 still at least partially overlaps with the corresponding anti-shake magnet 621, so as to ensure that sufficient magnetic attraction is generated between the anti-shake magnetic sheet 626 and the anti-shake magnet 621.

[0082] As attached Figure 3 , Attachment Fig.14 and attached Fig.17As shown, the motor 2 also includes an anti-shake support part 627, and the anti-shake support part 627 is arranged between the frame 4 and the base 3. The frame 4 and the base 3 clamp the anti-shake support part 627 under the magnetic attraction of the anti-shake magnetic sheet 626 and the anti-shake magnet 621, and the frame 4 is movably supported on the base 3 through the anti-shake support part 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, and 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, wherein 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, and 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 anti-shake coil 622 located on the third side 203 is between the first anti-shake support ball 6271 and the second anti-shake support ball 6272, and the two anti-shake coils 622 located on the second side 202 are between the second anti-shake support ball 6272 and the third anti-shake support ball 6273. More preferably, the first anti-shake support ball 6271, the second anti-shake support ball 6272 and the third anti-shake support ball 6273 have the same size.

[0083] Continue to refer to the attached Figure 3 , Attachment Fig.14 and attached Fig.17 In order 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 which protrude upward longitudinally. 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. Fig.15As shown, the bottom surface of the frame 4 and the areas corresponding to the three ball grooves of the first boss 304, the second boss 305 and the third boss 306 form a plane, and there is no need to use the bottom surface of the frame 4 to further constrain and limit the lateral movement of the frame 4 relative to the base 3. In some embodiments of the present invention, the bottom surface of the frame 4 and the areas corresponding to the three ball grooves of the first boss 304, the second boss 305 and the third boss 306 are provided with metal sheets to enhance the strength of the contact surface, prevent the frame 4 from being damaged by the anti-shake support balls, and prevent the lateral movement of the frame 4 relative to the base 3 from being affected.

[0084] It is worth mentioning that the present invention only needs to set three anti-shake support balls, namely, the first anti-shake support ball 6271, the second anti-shake support ball 6272 and the third anti-shake support ball 6273, to effectively and reliably support the frame 4 on the base 3, so that there is no need to set a fourth anti-shake support ball at the corner between the fourth side 204 and the first side 201 of the motor 2, and further, there is no need to set a fourth boss at the corner between the fourth side 204 and the first side 201. In this way, 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 the first carrier side guide groove 51 and the first frame side guide groove 41 can also have sufficient longitudinal dimensions to ensure that the first accommodation space formed between the first carrier side guide groove 51 and the first frame side guide groove 41 has sufficient longitudinal dimensions to meet the demand for more first focus support balls 6171 set in the first accommodation space. In other words, the first carrier side guide groove 51 and the first frame side guide groove 41 are arranged 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 arranged near the corner between the first side 201 and the third side 203, thereby not only ensuring that the first carrier side guide groove 51 has a sufficient longitudinal dimension, but also reducing the lateral dimension of the motor 2, which is conducive to the miniaturization of the motor 2 and the camera module.

[0085] As attached Figure 2 , Attachment Figure 3 And attached Fig. 9 To Attachment Fig.17As shown, the anti-shake circuit board 624 is only located on the third side 203, the second side 202 and the fourth side 204 of the motor 2, and the anti-shake circuit board 624 does not extend to the first side 201 of the motor 2, so that the focusing magnet 611 and the anti-shake circuit board 624 do not overlap in the longitudinal direction, that is, the focusing magnet 611 and the anti-shake circuit board 624 are offset from each other by a certain distance in the longitudinal direction. The offset distance between the focusing magnet 611 and the anti-shake circuit board 624 in the longitudinal direction is greater than the anti-shake stroke of the motor 2, so as to prevent the focusing magnet 611 from hitting the anti-shake circuit board 624 when realizing the optical image stabilization function, wherein the anti-shake stroke refers to the maximum moving distance of the frame 4 relative to the base 3 in the lateral direction. For details, please refer to the attached Figure 2 , since the focusing magnet 611 and the anti-shake 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 by the anti-shake circuit board 624. In this way, the carrier 5 and the focusing magnet 611 can be closer to the base 3 as a whole to reduce the height of the carrier 5 in the longitudinal direction, thereby reducing the longitudinal dimension of the motor 2, which is beneficial to the miniaturization of the motor 2 and the camera module. It is worth mentioning that when realizing the optical focus function, the focusing magnet 611 can move downward 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 anti-shake circuit board 624, thereby realizing the sinking setting of the focusing magnet 611 as much as possible to reduce the longitudinal dimension of the motor 2. As shown in the attached Figure 3 , Attachment Fig.14 , Attachment Fig.16 and attached Fig.17 As shown, the anti-shake circuit board 624 is roughly U-shaped to meet the above requirements.

[0086] As attached Fig.10As shown, since the first carrier side guide groove 51 is formed on the outer side of the carrier 5 on the side of the first side 201, and the anti-shake circuit board 624 does not extend to the first side 201 of the motor 2, the first carrier side guide groove 51 and the anti-shake circuit board 624 do not overlap in the longitudinal direction, that is, the first carrier side guide groove 51 and the anti-shake circuit board 624 are offset from each other by a certain distance in the longitudinal direction. The offset distance between the first carrier side guide groove 51 and the anti-shake circuit board 624 in the longitudinal direction is greater than the anti-shake stroke of the motor 2, so as to prevent the carrier 5 from hitting the anti-shake circuit board 624 when the optical anti-shake function is realized. In this way, in order to ensure that the first carrier side guide groove 51 has a sufficient longitudinal dimension, the first carrier side guide groove 51 can extend downward as much as possible, that is, extend in the direction close to the base 3, so as to reduce the longitudinal dimension of the carrier 5, thereby reducing the longitudinal dimension of the motor 2, and facilitating the miniaturization of the motor 2 and the camera module.

[0087] For further reference, see Fig. 9 To Attachment Fig.12 In order to reduce the longitudinal dimension of the motor 2, the carrier 5 is arranged as close to the base 3 as possible, and the anti-shake circuit board 624 is avoided by a first avoidance groove 53 formed at the bottom of the carrier 5 in the longitudinal direction.

[0088] As attached Fig.11 To Attachment Fig.13 As shown, the carrier 5 is also provided with a second avoidance groove 54, and the second avoidance groove 54 is formed on one side of the carrier 5 located on the third side 203, and the second avoidance groove 54 is located at the bottom position of the carrier 5 in the longitudinal direction. The second avoidance groove 54 is used to avoid the anti-shake coil 622 located on the third side 203, so that the lateral and longitudinal dimensions of the motor 2 can be reduced, which is conducive to the miniaturization of the motor 2 and the camera module. Further, according to the foregoing content, the second carrier side guide groove 52 does not extend to the bottom position of the carrier 5 in the longitudinal direction, so that the second avoidance groove 54 can extend to the bottom of 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 can further reduce the lateral and longitudinal dimensions of the motor 2.

[0089] As attached Fig.18As shown, since the focus magnet 611 and the focus coil 612 are located at the first side 201 of the motor 2, and the anti-shake magnet 621 and the anti-shake coil 622 are located at 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 focus magnet 611, the focus coil 612, the anti-shake magnet 621 and the anti-shake coil 622, the optical lens 10 is eccentrically arranged on the motor 2. Specifically, the center O1 of the lens bearing hole 50 of the carrier 5 for bearing the optical lens 10 is eccentric to 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 bearing hole 50, and the center O2 of the motor 2 is the intersection of the diagonal lines diagonally connected at the four corners of the motor 2.
