Description

TECHNICAL FIELD

[0001] The present application relates to the field of camera, and more particularly, to a camera module and a motor thereof. BACKGROUND

[0002] In electronic devices such as mobile phones and tablets, camera modules have become a standard configuration to meet the shooting needs. In order to ensure the shooting effect, the camera module is usually equipped with automatic focus (AF) or optical image stabilization (OIS) function. The implementation of optical image stabilization and optical focus function both rely on motor driving optical lens movement.

[0003] With the increasing demand of consumers for shooting quality, the anti-shake performance of the camera module is becoming more and more critical. For example, during video shooting, the device's jitter will cause the picture to be blurred, which seriously reduces the shooting effect of the video. Especially in long-focus shooting mode, even a small device jitter will be significantly magnified, causing the picture to shake violently. And when further using the digital zoom function, the picture shaking problem will be further aggravated, which seriously affects the shooting experience.

[0004] Therefore, it has become an urgent need in the market to design a motor and a camera module with good anti-shake performance. SUMMARY

DETAILED DESCRIPTION

[0050] Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part but not all of the embodiments of the present application, and the present application can be implemented in many different forms. It should be understood that the present application is not limited to the described embodiments.

[0051] As shown in Figures 1 to 10 , a camera module and a motor 1 according to an embodiment of the present application are illustrated. Specifically, as shown in Figure 1 , the camera module includes a motor 1, an optical lens 2 and a photosensitive assembly 3. The motor 1 is mounted on the photosensitive assembly 3. The photosensitive assembly 3 includes a photosensitive chip 301 configured to image by photoelectric conversion. The optical lens 2 is mounted on the motor 1 and held on the photosensitive path of the photosensitive assembly 3 by the motor 1; the optical lens 2 converges the incident light on the photosensitive chip 301 of the photosensitive assembly 3 and outputs the image by the photosensitive chip 301. The optical lens 2 defines an optical axis Z and an optical axis direction D. The optical axis direction D of the optical lens 2 is the length extension direction of the optical axis Z. The optical axis Z of the motor 1 is consistent with the optical axis Z of the optical lens 2; the optical axis direction D of the motor 1 is consistent with the optical axis direction D defined by the optical lens 2. The height direction of the camera module and the height direction of the motor 1 are consistent with the optical axis direction D. The motor 1 is used to drive the optical lens 2 to move to realize the functions of auto-focusing and optical image stabilization.

[0052] In some embodiments of the present application, the camera module further includes a filter assembly, which is arranged on the photosensitive path of the photosensitive assembly 3, so that the camera module can filter out unnecessary stray light through the filter assembly, for example, the filter assembly is arranged between the optical lens 2 and the photosensitive assembly 3. In an example of the present application, the filter assembly includes a bracket 302 and a filter element 303. The bracket 302 is supported on a circuit board 304, and the filter element 303 is fixed on the bracket 302.

[0053] In the present application, in the counterclockwise direction, the four sides of the motor 1 are defined as the first side, the second side, the third side and the fourth side respectively. Accordingly, the four sides of each component of the motor 1 are consistent with the four sides defined by the motor 1. In the present application, two mutually perpendicular axes perpendicular to the optical axis Z are defined as the first axis X and the second axis Y respectively; the length extension direction of the first axis X is the first axis direction D1; the length extension direction of the second axis Y is the second axis direction D2. Accordingly, the first axis direction D1 and the second axis direction D2 are perpendicular to the optical axis direction D respectively, and the first axis direction D1 and the second axis direction D2 are perpendicular to each other. In an example of the present application, the first axis X crosses between the first side and the third side of the motor 1; the second axis Y crosses between the second side and the fourth side of the motor 1.

[0054] As shown in Figure 2 , the motor 1 comprises a fixed assembly 10, a movable assembly 20, a driving assembly 30, a supporting assembly 40, a magnetic assembly 50, a sensing assembly 60 and a conductive assembly 70.

[0055] In an embodiment of the present application, as shown in Figure 1 and Figure 2 , the fixed assembly 10 comprises a base 11 and a top cover 12, wherein the top cover 12 and the base 11 are buckled and fixed to each other, and enclose a receiving cavity between the base 11 and the top cover 12. The receiving cavity is used for accommodating other elements.

[0056] In this embodiment, the base 11 comprises a base body 111 and two base side walls respectively extending upward from two sides of the base body 111. The base body 111 is mainly used for providing bottom support. The base body 111 comprises a first base bottom edge 1111, a second base bottom edge 1112, a third base bottom edge 1113 and a fourth base bottom edge 1114 in sequence in the counterclockwise direction. The first base bottom edge 1111 is located at the first side of the motor 1, the second base bottom edge 1112 is located at the second side of the motor 1, the third base bottom edge 1113 is located at the third side of the motor 1, and the fourth base bottom edge 1114 is located at the fourth side of the motor 1. The first base bottom edge 1111, the second base bottom edge 1112, the third base bottom edge 1113 and the fourth base bottom edge 1114 enclose a base through hole 101, wherein the base through hole 101 corresponds to the optical lens 2, so that the light emitted by the optical lens 2 can enter the photosensitive assembly 3. The two base side walls are respectively a first base side wall 112 and a second base side wall 113. The first base side wall 112 and the second base side wall 113 are opposite in the second axial direction D2. The first base side wall 112 is located at the fourth side of the motor 1, and the second base side wall 113 is located at the second side of the motor 1.

[0057] It is worth mentioning that, in the present application, the base 11 is not provided with side walls at the first side and the third side, which can reduce the lateral size of the motor 1 to a certain extent.

[0058] The movable assembly 20 is used for carrying the optical lens 2, and is movably arranged in the fixed assembly 10. Specifically, as shown in Figure 2As shown, the movable component 20 includes a stabilizing carrier 21. The stabilizing carrier 21 is movably mounted within the receiving cavity of the fixed component 10. More specifically, the stabilizing carrier 21 is movably mounted within the base 11. The stabilizing carrier 21 is adapted to move relative to the base 11 in a direction perpendicular to the optical axis Z. More specifically, the stabilizing carrier 21 is adapted to move relative to the base 11 along a first axial direction D1 and a second axial direction D2.

[0059] The image stabilization carrier 21 includes, in a counter-clockwise direction in the circumferential direction, a first image stabilization sidewall 211, a second image stabilization sidewall 212, a third image stabilization sidewall 213, and a fourth image stabilization sidewall 214. The first image stabilization sidewall 211 is located on the first side of the motor 1, the second image stabilization sidewall 212 is located on the second side of the motor 1, the third image stabilization sidewall 213 is located on the third side of the motor 1, and the fourth image stabilization sidewall 214 is located on the fourth side of the motor 1.

[0060] like Figure 2 As shown, the movable component 20 also includes a focusing carrier 22. The focusing carrier 22 is movably mounted within the image stabilization carrier 21 and configured to house the optical lens 2 therein. In other words, the optical lens 2 is fixed to the focusing carrier 22; the image stabilization carrier 21 indirectly supports the optical lens 2 via the focusing carrier 22; and the focusing carrier 22 moves together with the image stabilization carrier 21 relative to the base 11 in a direction perpendicular to the optical axis Z. The focusing carrier 22 is also configured to move relative to the image stabilization carrier 21 and the base 11 along a predetermined optical axis direction D.

[0061] The drive assembly 30 is used to drive the image stabilization carrier 21 to move relative to the base 11 in a direction perpendicular to the optical axis D, and to drive the focusing carrier 22 to move relative to the image stabilization carrier 21 and the base 11 in the optical axis D.

[0062] Accordingly, in one embodiment of this application, as Figure 2 As shown, the driving assembly 30 includes an image stabilization driving assembly 31 and a focusing driving assembly 32. The image stabilization driving assembly 31 is configured to drive the image stabilization carrier 21 to move relative to the base 11 along the first axis direction D1 and the second axis direction D2, and through the image stabilization carrier 21, drive the focusing carrier 22 and the optical lens 2 to move along the first axis direction D1 and the second axis direction D2, thereby performing optical image stabilization. The focusing driving assembly 32 is configured to drive the focusing carrier 22 to move relative to the image stabilization carrier 21 and the base 11 along the optical axis direction D, thereby driving the optical lens 2 to move relative to the image stabilization carrier 21 along the optical axis direction D, thereby performing autofocus.

[0063] It is worth mentioning that, in some embodiments, the focusing carrier 22 is fixed with all the optical lenses of the optical lens 2, so as to realize the optical focusing function; in other embodiments, the focusing carrier 22 is fixed with only part of the optical lenses of the optical lens 2, and the focal plane of the optical lens 2 is overlapped with the photosensitive surface of the photosensitive assembly 3 by changing the focal length of the optical lens 2, so as to realize the optical focusing function.

[0064] In the embodiment of the present application, the driving of the anti-shake carrier 21 and the focusing carrier 22 is realized by the cooperation of magnets and coils. Accordingly, as shown in Figure 2 The anti-shake driving assembly 31 includes a first anti-shake magnet 311, a first anti-shake coil 312, a second anti-shake magnet 313 and a second anti-shake coil 314. The focusing driving assembly 32 includes a focusing magnet 321 and a focusing coil 322.

[0065] The first anti-shake coil 312 and the first anti-shake magnet 311 are used to drive the anti-shake carrier 21 to move along the second axis direction D2 relative to the base 11, and then drive the focusing carrier 22 and the optical lens 2 to move along the second axis direction D2 relative to the base 11 through the anti-shake carrier 21. The second anti-shake coil 314 and the second anti-shake magnet 313 are used to drive the anti-shake carrier 21 to move along the first axis direction D1 relative to the base 11, and then drive the focusing carrier 22 and the optical lens 2 to move along the first axis direction D1 relative to the base 11 through the anti-shake carrier 21.

[0066] In an embodiment of the present application, as shown in Figure 2 The first anti-shake coil 312 and the first anti-shake magnet 311 are opposite in the optical axis direction D, and the second anti-shake coil 314 and the second anti-shake magnet 313 are opposite in the optical axis direction D, so as to facilitate the distance between the first anti-shake coil 312 and the first anti-shake magnet 311 along the optical axis direction D and the distance between the second anti-shake coil 314 and the second anti-shake magnet 313 along the optical axis direction D not to change during the optical anti-shake process of the motor 1, improve the long-stroke anti-shake ability of the motor 1, and reduce the attenuation of the driving force between the first anti-shake coil 312 and the first anti-shake magnet 311 and between the second anti-shake coil 314 and the second anti-shake magnet 313 under long-stroke movement.

[0067] Specifically, the anti-shake driving assembly 31 is a moving magnet structure. The moving magnet structure refers to the interaction between the coil and the magnet, the magnet moves relative to the coil, and then drives the components fixed with the magnet to move. More specifically, the first anti-shake coil 312 and the first anti-shake magnet 311 are arranged below the second anti-shake side wall 212. Accordingly, the first anti-shake coil 312 and the first anti-shake magnet 311 are located on the second side of the motor 1. In an embodiment of the present application, the first anti-shake magnet 311 is fixed to the bottom surface of the second anti-shake side wall 212, and the first anti-shake coil 312 is fixed to the bottom edge 1112 of the second bottom seat. Since the first anti-shake magnet 311 is fixed to the anti-shake carrier 21, and the first anti-shake coil 312 is fixed to the bottom seat 11, when the first anti-shake coil 312 is energized, the first anti-shake magnet 311 moves relative to the first anti-shake coil 312 along the second axis direction D2, so that the anti-shake carrier 21 is driven by the first anti-shake magnet 311 to move relative to the bottom seat 11 along the second axis direction D2.

[0068] The second anti-shake coil 314 and the second anti-shake magnet 313 are arranged below the third anti-shake side wall 213. Accordingly, the second anti-shake coil 314 and the second anti-shake magnet 313 are located on the third side of the motor 1. The second anti-shake magnet 313 is fixed to the bottom surface of the third anti-shake side wall 213, and the second anti-shake coil 314 is fixed to the bottom edge 1113 of the third bottom seat. Since the second anti-shake magnet 313 is fixed to the anti-shake carrier 21, and the second anti-shake coil 314 is fixed to the bottom seat 11. When the second anti-shake coil 314 is energized, the second anti-shake magnet 313 moves relative to the second anti-shake coil 314 along the first axis direction D1, so that the anti-shake carrier 21 is driven by the second anti-shake magnet 313 to move relative to the bottom seat 11 along the first axis direction D1. Through the driving of the two groups of anti-shake coils-anti-shake magnets, the anti-shake carrier 21 is translated relative to the bottom seat 11 in the horizontal plane perpendicular to the optical axis Z.

[0069] The first anti-shake magnet 311 can be designed to be at least partially embedded in the anti-shake carrier 21, and / or the first anti-shake coil 312 can be designed to be at least partially embedded in the bottom seat 11, so as to reduce the longitudinal space occupied by the first anti-shake coil 312 and the first anti-shake magnet 311, and thereby reduce the longitudinal dimension of the motor 1. The second anti-shake magnet 313 can be designed to be at least partially embedded in the anti-shake carrier 21, and / or the second anti-shake coil 314 can be designed to be at least partially embedded in the bottom seat 11, so as to reduce the longitudinal space occupied by the second anti-shake coil 314 and the second anti-shake magnet 313, and thereby reduce the longitudinal dimension of the motor 1.

[0070] The focusing coil 322 and the focusing magnet 321 are configured to drive the focusing carrier 22 to move along the optical axis direction D. As shown in Figure 1 and Figure 2 In an embodiment of the present application, the focusing coil 322 and the focusing magnet 321 are opposite to each other along the first axis direction D1, so that the distance between the focusing magnet 321 and the focusing coil 322 along the first axis direction D1 does not change during the focusing process, which improves the long stroke focusing capability of the motor 1.

[0071] The focusing driving assembly 32 is of a moving magnet type. Specifically, the focusing coil 322 and the focusing magnet 321 are arranged on the first side of the focusing carrier 22. Accordingly, the focusing coil 322 and the focusing magnet 321 are located on the first side of the motor 1. In an embodiment of the present application, the focusing magnet 321 is fixed to the first side of the focusing carrier 22, and the focusing coil 322 is fixed to the first side (e.g., the first anti-vibration side wall 211) of the anti-vibration carrier 21 or the first side of the base 11. When the focusing coil 322 is energized, the focusing magnet 321 moves relative to the focusing coil 322 along the optical axis direction D, so that the focusing carrier 22 moves relative to the anti-vibration carrier 21 and the base 11 along the optical axis direction D.

[0072] Further, the focusing magnet 321 can be designed to be at least partially embedded in the focusing carrier 22, and / or the focusing coil 322 can be designed to be at least partially embedded in the anti-vibration carrier 21, so as to reduce the lateral space occupied by the focusing driving assembly 32, and thus reduce the lateral size of the motor 1.

[0073] In an embodiment of the present application, as shown in Figure 2 The support assembly 40 includes an anti-vibration support portion 41 and a focusing support portion 42. The anti-vibration support portion 41 is configured to support the anti-vibration carrier 21. The focusing support portion 42 is configured to support the focusing carrier 22.

[0074] The anti-vibration support portion 41 is arranged between the anti-vibration carrier 21 and the base 11. As shown in Figure 2 The anti-vibration support portion 41 includes three balls 410, which are arranged between the anti-vibration carrier 21 and the base 11, so that the anti-vibration carrier 21 can move relative to the base 11 with small friction.

[0075] In one example of the present application, the three anti-shake supporting balls 410 are respectively arranged at the corners connecting the first side and the second side of the motor 1, the corners connecting the second side and the third side of the motor 1, and the corners connecting the third side and the fourth side of the motor 1.

[0076] Specifically, as shown in Figure 2 and Figure 5 the anti-shake carrier 21 facing the side of the base 11 (i.e. the lower side of the anti-shake carrier 21) is provided with three carrier ball grooves 201. The three carrier ball grooves 201 on the side of the anti-shake carrier 21 facing the base 11 are respectively arranged at the three corners of the anti-shake carrier 21, i.e. the corner between the first anti-shake side wall 211 and the second anti-shake side wall 212, the corner between the second anti-shake side wall 212 and the third anti-shake side wall 213, and the corner between the third anti-shake side wall 213 and the fourth anti-shake side wall 214.

[0077] The side of the base 11 facing the anti-shake carrier 21 (i.e. the upper side of the base 11) is also provided with three ball grooves at the corresponding positions (i.e. the positions opposite to the three carrier ball grooves 201 in the optical axis direction D), which are the base ball grooves 102. The three base ball grooves 102 are respectively arranged at the three corners of the base 11, i.e. the corner between the first base bottom edge 1111 and the second base bottom edge 1112, the corner between the second base bottom edge 1112 and the third base bottom edge 1113, and the corner between the third base bottom edge 1113 and the fourth base bottom edge 1114.

[0078] The three carrier ball grooves 201 and the three base ball grooves 102 correspond to each other, forming ball accommodation spaces for accommodating the three anti-shake supporting balls 410, for defining the movable space of the anti-shake supporting balls 410.

[0079] It is worth mentioning that in the present application, the carrier ball grooves 201 and the base ball grooves 102 are all flat bottom ball grooves without guiding function, and the sizes of the ball accommodation spaces formed by the carrier ball grooves 201 and the base ball grooves 102 in the first axis direction D1 and the second axis direction D2 are greater than the radial size of the anti-shake supporting balls 410, so that the anti-shake carrier 21 can move in any direction in the horizontal plane relative to the base 11. It can be understood that the present application only uses one layer of anti-shake supporting balls 410 to support the anti-shake carrier 21, so that the height of the motor 1 is reduced.

[0080] In an embodiment of the present application, the focus support 42 is disposed on the side of the focus carrier 22 where the focus drive assembly 32 is located. In this way, the point of action of the force generated by the focus drive assembly 32 is closer to the focus support 42, thereby reducing the overturning moment generated when focusing. Accordingly, in an embodiment of the present application, the focus drive assembly 32 and the focus support 42 are disposed on the first side of the focus carrier 22.

[0081] In an embodiment of the present application, as shown in Figure 2 and Figure 3 The focus support 42 includes two guide rods, where the two guide rods are a first guide rod 421 and a second guide rod 422. The first guide rod 421 and the second guide rod 422 are fixed between the anti-vibration carrier 21 and the focus carrier 22 and are disposed on both sides of the focus magnet 321, respectively. The length extension direction of the first guide rod 421 and the second guide rod 422 is consistent with the optical axis direction D. The length of the first guide rod 421 and the second guide rod 422 is greater than or equal to the height of the focus carrier 22, or even greater than the movement stroke of the focus carrier 22 along the optical axis direction D, so that the focus carrier 22 can be supported within the movement stroke.

[0082] In an example of the present application, the first guide rod 421 and the second guide rod 422 are fixed to the anti-vibration carrier 21. It can be designed that the bottom end of the first guide rod 421 and the bottom end of the second guide rod 422 are fixed to the anti-vibration carrier 21, or the circumferential side of the first guide rod 421 and the circumferential side of the second guide rod 422 are fixed to the anti-vibration carrier 21.

[0083] It should be understood that the first guide rod 421 and the second guide rod 422 can also be fixed between the anti-vibration carrier 21 and the focus carrier 22 in other ways, for example, by being fixed to the anti-vibration carrier 21 or by being fixed to the focus carrier 22.

[0084] In an example of the present application, the first guide rod 421 and the second guide rod 422 are integrally formed with the anti-vibration carrier 21.

[0085] The focus carrier 22 has two guide rod grooves. The two guide rod grooves are a first guide rod groove 221 and a second guide rod groove 222. The first guide rod groove 221 and the second guide rod groove 222 extend along the optical axis direction D.

[0086] In particular, the first guide rod slot 221 is arranged at a position of the motor 1 where no ball 410 is arranged, for example, at a corner between the first side and the fourth side of the motor 1, and is a guide slot with a lateral guiding function, the width of which gradually increases from inside to outside in the depth direction, and the orthographic projection on a plane perpendicular to the optical axis Z is substantially V-shaped; the second guide rod slot 222 is a planar slot without a lateral guiding function, the width of which is substantially uniform from inside to outside in the depth direction.

[0087] It is worth mentioning that the arrangement of the balls 410 only on three sides of the motor 1 provides a space for the first guide rod slot 221 which is V-shaped and requires a larger arrangement space. Correspondingly, in order not to increase the lateral dimension of the motor 1, the second guide rod slot 222 opposite to the first guide rod slot 221 in the second axis direction D2 can be a guide rod slot with a planar slot bottom surface without a lateral guiding function. Correspondingly, the arrangement of the two guide rod slots is as follows: one of the two guide rod slots is a V-shaped guide rod slot with a guiding function, and the other is a guide rod slot without a lateral guiding function. Furthermore, in order to reduce the space occupied by the guide rod slot, the second guide rod slot 222 close to the balls 410 is arranged as a semi-open slot, so that the size thereof is smaller.

[0088] In an embodiment of the present application, as shown in Figure 2 The focusing carrier 22 has at least three support positions formed on the side wall thereof, namely a first support position 223, a second support position 224, and a third support position 225. In the relative arrangement direction (i.e., the second axis direction D2) of the first guide rod 421 and the second guide rod 422, the first support position 223 and the second support position 224 are located on the same side, and the third support position 225 is located on the side opposite to the first support position 223 and the second support position 224 of the focusing drive assembly 32. The first support position 223 is located above the second support position 224. The first support position 223 is close to the top surface of the focusing carrier 22 of the focusing carrier 22. The second support position 224 is close to the bottom surface of the focusing carrier 22 of the focusing carrier 22. The second support position 224 is closer to the bottom surface of the focusing carrier 22 than the third support position 225. The first support position 223, the second support position 224, and the third support position 225 form a triangular support surface with the focusing support portion 42.

[0089] In an embodiment of the present application, the first guide rod 421 abuts against the first support position 223 and the second support position 224, and the second guide rod 422 abuts against the third support position 225.

[0090] Correspondingly, in an embodiment of the present application, the number of support positions between the focusing carrier 22 and the first guide rod 421 is at least two, which are the first support position 223 and the second support position 224 respectively. The number of support positions between the focusing carrier 22 and the second guide rod 422 is at least one, which is the third support position 225.

[0091] Specifically, the focusing carrier 22 is provided with a contact protrusion 210 at each of the two opposite ends in the height direction of the first guide rod groove 221; the first guide rod 421 is in contact with the contact protrusions 210 at the two opposite ends in the height direction of the first guide rod groove 221; and the contact protrusions 210 at the two opposite ends in the height direction of the first guide rod groove 221 form the first support position 223 and the second support position 224. The focusing carrier 22 is provided with a contact protrusion 210 at the middle in the height direction of the second guide rod groove 222; the second guide rod 422 is in contact with the contact protrusion 210 at the middle in the height direction of the second guide rod groove 222; and the contact protrusion 210 at the middle in the height direction of the second guide rod groove 222 forms the third support position 225.

[0092] Correspondingly, in the optical axis direction D, the height of the third support position 225 is higher than that of the second support position 224 and lower than that of the first support position 223; the first support position 223, the second support position 224 and the third support position 225 form a triangular position relationship. The first support position 223, the second support position 224 and the third support position 225 form a triangular support surface, which helps to reduce the friction between the guide rod and the guide rod groove and also helps to maintain the stability of the focusing carrier 22 adsorbed on the anti-shake carrier 21 and reduce the risk of the focusing carrier 22 overturning.

[0093] Since the second guide rod 422 only needs to be in contact with one support position, the length of the second guide rod 422 can be shorter than that of the first guide rod 421. In this way, the parallelism of the second guide rod 422 can be maintained, and more space can be provided for the arrangement of other components.

[0094] It is worth mentioning that the focusing support part 42 can also be implemented in other ways and achieve a triangular support in other ways. The focusing support part 42 can be implemented as a combination of a guide rod and a sliding block, or a combination of a guide rod and a ball 410, or a combination of a sliding block and a ball 410. The component in the focusing support part 42 that is in contact with the first support position 223 can be a guide rod, a sliding block or a ball 410, the component in contact with the second support position 224 can be a guide rod, a sliding block or a ball 410, and the component in contact with the third support position 225 can be a guide rod, a sliding block or a ball 410.

[0095] As shown in Figure 2 and Figure 5 The anti-shake magnetic assembly 50 includes an anti-shake magnetic part 51 and a focusing magnetic part 52. The anti-shake magnetic part 51 is used to attract the anti-shake carrier 21 to the base 11; the focusing magnetic part 52 is used to attract the focusing carrier 22 to the anti-shake carrier 21.

[0096] The focusing magnetic part 52 is located on the side of the focusing coil 322 away from the focusing magnet 321. The focusing magnetic part 52 has magnetic permeability and can be attracted to the focusing magnet 321. The magnetic attraction between the focusing magnetic part 52 and the focusing magnet 321 causes the focusing carrier 22 and the anti-shake carrier 21 to approach each other, and the focusing carrier 22 is more tightly supported by the focusing support part 42, which can improve the driving stability and prevent the focusing carrier 22 and the anti-shake carrier 21 from falling. In other words, the magnetic attraction between the focusing magnetic part 52 and the focusing magnet 321 causes the focusing carrier 22 to be attracted to the side wall of the anti-shake carrier 21.

[0097] In an example of the present application, the focusing magnetic part 52 is in the form of a sheet. It should be understood that in theory, the focusing magnetic sheet can also be in other forms.

[0098] It is worth mentioning that in the present application, it is desirable that the resultant force of the magnetic attraction between the focusing carrier 22 and the anti-shake carrier 21 is biased to the side where the first support position 223 and the second support position 224 are located, more specifically, it is desirable that the resultant force of the magnetic attraction between the focusing carrier 22 and the anti-shake carrier 21 is biased to the side where the first support position 223 and the second support position 224 are located in the length direction of the focusing magnet 321 compared to the side where the third support position 225 is located, so that the focusing carrier 22 is not prone to overturning relative to the anti-shake carrier 21, i.e., it is not prone to deflection relative to the anti-shake carrier 21 with the first support position 223 and the second support position 224 as the pivot, and for this purpose, the focusing magnetic part 52 affecting the magnetic field in which the focusing carrier 22 is located is specifically designed.

[0099] Specifically, in an example of the present application, as shown in Figure 2 and Figure 4As shown, the focusing magnetic attraction member 52 is provided with a first hollow region 521 on the side away from the guide groove (i.e., the first guide rod groove 221), that is, the side away from the first support position 223 and the second support position 224, for example, the focusing magnetic attraction member 52 is provided with at least one first hollow hole on the side away from the first support position 223 and the second support position 224, so that the focusing magnetic attraction member 52 is provided with a first hollow region 521 on the side away from the first support position 223 and the second support position 224. In this way, the overlapping region of the focusing magnetic attraction member 52 and the focusing magnet 321 in the relative arrangement direction of the focusing magnet 321 and the focusing coil 322 is biased towards the first support position 223 and the second support position 224, the first guide rod 421 and the first guide rod groove 221, so that the magnetic attraction force between the focusing magnetic attraction member 52 and the focusing magnet 321 is biased towards the side where the first support position 223 and the second support position 224 are located, thereby making the resultant force of the magnetic attraction force between the focusing carrier 22 and the anti-shake carrier 21 biased towards the side where the first support position 223 and the second support position 224 are located, and also biased towards the first guide rod 421 and the V-shaped first guide rod groove 221 with lateral guiding function, thereby improving the support stability of the focusing carrier 22 on the anti-shake carrier 21, so that the focusing carrier 22 is not prone to overturning relative to the anti-shake carrier 21, that is, not prone to deflection relative to the anti-shake carrier 21 with the first support position 223 and the third support position 225 as the pivot, or with the second support position 224 and the third support position 225 as the pivot.

[0100] The height dimension of the focusing magnetic attraction member 52 is greater than the height dimension of the focusing magnet 321, that is, the size of the focusing magnetic attraction member 52 is greater than the size of the focusing magnet 321 in the optical axis direction D. Further, in an embodiment of the present application, the height dimension of the focusing magnetic attraction member 52 is greater than or equal to the sum of the height of the focusing magnet 321 and the movement stroke of the focusing magnet 321 in the optical axis direction D.

[0101] As shown in FIG. 6, the focusing magnetic attraction member 52 is provided with a second hollow region 522 on the side away from the first guide rod 421, that is, the side away from the first support position 223 and the second support position 224, for example, the focusing magnetic attraction member 52 is provided with at least one second hollow hole on the side away from the first support position 223 and the second support position 224, so that the focusing magnetic attraction member 52 is provided with a second hollow region 522 on the side away from the first support position 223 and the second support position 224. In this way, the overlapping region of the focusing magnetic attraction member 52 and the focusing magnet 321 in the relative arrangement direction of the focusing magnet 321 and the focusing coil 322 is biased towards the first support position 223 and the second support position 224, the first guide rod 421 and the first guide rod groove 221, so that the magnetic attraction force between the focusing magnetic attraction member 52 and the focusing magnet 321 is biased towards the side where the first support position 223 and the second support position 224 are located, thereby making the resultant force of the magnetic attraction force between the focusing carrier 22 and the anti-shake carrier 21 biased towards the side where the first support position 223 and the second support position 224 are located, and also biased towards the first guide rod 421 and the V-shaped first guide rod groove 221 with lateral guiding function, thereby improving the support stability of the focusing carrier 22 on the anti-shake carrier 21, so that the focusing carrier 22 is not prone to overturning relative to the anti-shake carrier 21, that is, not prone to deflection relative to the anti-shake carrier 21 with the first support position 223 and the third support position 225 as the pivot, or with the second support position 224 and the third support position 225 as the pivot. Figure 5As shown, the anti-shake magnetic attraction part 51 includes a first anti-shake magnetic attraction piece 511 and a second anti-shake magnetic attraction piece 512. The first anti-shake magnetic attraction piece 511 and the second anti-shake magnetic attraction piece 512 are fixed to the base 11 and respectively opposite to the first anti-shake magnet 311 and the second anti-shake magnet 313. Specifically, the first anti-shake magnetic attraction piece 511 is below the first anti-shake coil 312 in the optical axis direction D and opposite to the first anti-shake magnet 311 in the optical axis direction D, so that the anti-shake carrier 21 is attracted to the base 11 by the magnetic attraction force between the first anti-shake magnet 311 and the first anti-shake magnetic attraction piece 511 in the optical axis direction D. The second anti-shake magnetic attraction piece 512 is below the second anti-shake coil 314 in the optical axis direction D and opposite to the second anti-shake magnet 313 in the optical axis direction D, so that the anti-shake carrier 21 is attracted to the base 11 by the magnetic attraction force between the second anti-shake magnet 313 and the second anti-shake magnetic attraction piece 512 in the optical axis direction D.

[0102] In an embodiment of the present application, the first anti-shake magnetic attraction piece 511 and the second anti-shake magnetic attraction piece 512 can be separately arranged. It should be understood that in other embodiments of the present application, the first anti-shake magnetic attraction piece 511 and the second anti-shake magnetic attraction piece 512 are integrally connected, so that the first anti-shake magnetic attraction piece 511 and the second anti-shake magnetic attraction piece 512 can be installed together to simplify the installation.

[0103] In an embodiment of the present application, the first anti-shake magnetic attraction piece 511 and / or the second anti-shake magnetic attraction piece 512 are embedded in the base 11 to facilitate the improvement of the structural strength of the base 11 and also to facilitate the reduction of the height dimension of the motor 1.

[0104] It is worth mentioning that in an embodiment of the present application, the magnetic attraction force of the first anti-shake magnetic attraction piece 511, the second anti-shake magnetic attraction piece 512 and the first anti-shake magnet 311, the first anti-shake magnetic attraction piece 511 can also be used for resetting the anti-shake carrier 21.

[0105] As shown in Figure 2 and Figure 5 As shown, the sensing assembly 60 includes a focus sensing element 61, a first anti-shake sensing element 62 and a second anti-shake sensing element 63. The focus sensing element 61 is used to obtain the position change information of the focus carrier 22 relative to the anti-shake carrier 21; the first anti-shake sensing element 62 and the second anti-shake sensing element 63 are used to obtain the position change information of the anti-shake carrier 21 relative to the base 11.

[0106] In an embodiment of the present application, the focus sensing element 61 is opposite to the focus magnet 321, and the position change information of the focus magnet 321 is obtained by obtaining the magnetic field change information of the focus magnet 321, so as to obtain the position change information of the focus carrier 22 fixed by the focus magnet 321, and mainly obtain the position change information of the focus carrier 22 relative to the anti-shake carrier 21 along the optical axis direction D.

[0107] Further, the focus sensing element 61 can be arranged outside the focus coil 322. In an example of the present application, the focus magnetic attraction element 52 is located on the side of the focus sensing element 61 away from the focus magnet 321, i.e., the back side of the focus sensing element 61.

[0108] It is worth mentioning that, in this example, the focus magnetic attraction element 52 has a second hollow area 522 corresponding to the part of the focus sensing element 61, so as to reduce the influence of the focus magnetic attraction element 52 on the focus sensing element 61 (the focus magnetic attraction element 52 will change the magnetic field of the focus magnet 321, and the second hollow area 522 can reduce the influence), for example, at least one second hollow hole is arranged corresponding to the part of the focus sensing element 61, so that the focus magnetic attraction element 52 has the second hollow area 522 corresponding to the part of the focus sensing element 61.

[0109] It is also worth mentioning that the second hollow area 522 can at least partially coincide with the first hollow area 521, or can not coincide at all.

[0110] Specifically, in an example of the present application, the focus sensing element 61 is located away from the first guide rod slot 221, and at least one first hollow hole at least partially coincides with at least one second hollow hole, so that the second hollow area 522 at least partially coincides with the first hollow area 521, or at least one second hollow hole is not only used to reduce the influence of the focus magnetic attraction element 52 on the focus sensing element 61, but also used as the first hollow hole to reduce the overlapping area of the focus magnetic attraction element 52 and the focus magnet 321 away from the first guide rod slot 221.

[0111] In another example of the present application, the focus sensing element 61 is located close to the first guide rod slot 221, and any first hollow hole does not coincide with the second hollow hole, so that the second hollow area 522 can not coincide with the first hollow area 521 at all.

[0112] The first anti-shake sensing element 62 is arranged opposite to the bottom surface of the first anti-shake magnet 311. By obtaining the magnetic field change information of the first anti-shake magnet 311, the position change information of the first anti-shake magnet 311 is obtained, and thus the position change information of the anti-shake carrier 21 fixed with the first anti-shake magnet 311 is obtained, mainly the position change information of the anti-shake carrier 21 relative to the base 11 along the second axis direction D2.

[0113] Further, the first anti-shake sensing element 62 is located below the first anti-shake coil 312 and is fixed to the base 11. As shown in Figure 5 In one example of the present application, the first anti-shake magnetic member 511 has a first through hole 5111, and the first anti-shake sensing element 62 is arranged in the first through hole 5111 of the first anti-shake magnetic member 511.

[0114] The second anti-shake sensing element 63 is arranged opposite to the bottom surface of the second anti-shake magnet 313. By obtaining the magnetic field change information of the second anti-shake magnet 313, the position change information of the second anti-shake magnet 313 is obtained, and thus the position change information of the anti-shake carrier 21 fixed with the second anti-shake magnet 313 is obtained, mainly the position change information of the anti-shake carrier 21 relative to the base 11 along the first axis direction D1.

[0115] Further, the second anti-shake sensing element 63 is located below the second anti-shake coil 314 and is fixed to the base 11. In one example of the present application, the second anti-shake magnetic member 512 has a second through hole 5121, and the second anti-shake sensing element 63 is arranged in the second through hole 5121 of the second anti-shake magnetic member 512.

[0116] The focus sensing element 61, the first anti-shake sensing element 62, and the second anti-shake sensing element 63 can be Hall sensors, or TMR, or driving chips with position sensing function.

[0117] As shown in Figure 2 , Figure 3 and Figure 5 The conductive assembly 70 includes the base circuit board 71, an elastic circuit board 72, and a base conductive insert 73.

[0118] The base circuit board 71 is fixed to the base 11 and is electrically connected to the anti-shake driving assembly 31. The first anti-shake sensing element 62, the second anti-shake sensing element 63, and the anti-shake magnetic attraction part 51 are all fixed to the base 11 by being fixed to the base circuit board 71. The first anti-shake sensing element 62 and the second anti-shake sensing element 63 are also electrically connected to the base circuit board 71.

[0119] In one example of the present application, the first and second anti-shake sensing elements 62 and 63 are fixed to the bottom surface of the base circuit board 71. The first and second anti-shake coils 312 and 314 are located above the base circuit board 71. In this way, the anti-shake magnetic attraction part 51, the first and second anti-shake sensing elements 62 and 63 are isolated from the first and second anti-shake coils 312 and 314 by the base circuit board 71.

[0120] In one example of the present application, the base 11 has a groove corresponding to the base circuit board 71 for accommodating the base circuit board 71.

[0121] In one example of the present application, the base 11 has a groove corresponding to the first and second anti-shake sensing elements 62 and 63 for accommodating the first and second anti-shake sensing elements 62 and 63, or the first and second anti-shake sensing elements 62 and 63 are embedded in the base 11.

[0122] In one example of the present application, the anti-shake magnetic attraction part 51 is fixed to the bottom surface of the base circuit board 71. The base 11 has a groove corresponding to the anti-shake magnetic attraction part 51 for accommodating the anti-shake magnetic attraction part 51, or the anti-shake magnetic attraction part 51 is embedded in the base 11.

[0123] The base conductive inserts 73 are embedded in the base 11, the number of the base conductive inserts 73 is at least two, and both ends of each of the at least two base conductive inserts 73 are exposed, one end of which extends to the inside of the base through hole 101 and is exposed for electrical connection with the base circuit board 71, so that the base circuit board 71 can be electrically connected with other components (for example, the photosensitive assembly 3) of the camera module through the base conductive inserts 73; the other end extends outward and protrudes out of the base 11 to form a pin group for electrical connection with other components (for example, the photosensitive assembly 3) of the camera module. In one example of the present application, the pin group is located on the fourth side of the motor 1.

[0124] The elastic circuit board 72 is electrically connected to the focus driving assembly 32. Specifically, a part of the elastic circuit board 72 is fixed to the anti-shake carrier 21 and electrically connected to the focus coil 322 and the focus sensing element 61; another part of the elastic circuit board 72 is fixed to the base 11. In this way, the elastic circuit board 72 becomes a conductive medium extending between the anti-shake carrier 21 and the base 11, so that the electrical elements (for example, the focus coil 322 and the focus sensing element 61) arranged on the anti-shake carrier 21 are conducted to the base 11 through the elastic circuit board 72, and are electrically connected to other components of the camera module, for example, the photosensitive assembly 3, through the elastic circuit board 72.

[0125] It is worth mentioning that, in a variant embodiment of the present application, the anti-shake driving assembly 31 is a moving coil type structure. The moving coil type structure refers to the interaction between the coil and the magnet, the coil moves relative to the magnet, and then drives the components fixed with the coil to move. The first anti-shake coil 312 and the second anti-shake coil 314 are installed on the anti-shake carrier 21. In particular, in this variant embodiment, the first anti-shake coil 312 and the second anti-shake coil 314 can be electrically connected to the elastic circuit board 72, and are conducted to the base 11 through the elastic circuit board 72, so as to be electrically connected to other components of the camera module, for example, the photosensitive assembly 3. In this variant embodiment, the elastic circuit board 72 is electrically connected to the anti-shake driving assembly 31.

[0126] Further, the elastic circuit board 72 has elasticity, which is suitable for avoiding or reducing the risk of the anti-shake carrier 21 rotating relative to the base 11 around the optical axis Z.

[0127] The elastic circuit board 72 includes a mover fixing part 721, a stator fixing part 722, and an elastic connecting part 723. The elastic connecting part 723 is connected between the mover fixing part 721 and the stator fixing part 722.

[0128] The mover fixing part 721 is fixed to the anti-shake carrier 21. The stator fixing part 722 is fixed to the base 11. The elastic connecting part 723 has elasticity, and the restoring force generated by the elastic deformation of the elastic connecting part 723 reduces the risk of the anti-shake carrier 21 rotating relative to the base 11 around the optical axis Z, which helps to improve the imaging clarity. Further, the elastic circuit board 72 can also be used for the reset (return to the initial position) of the anti-shake carrier 21 in the base 11, which can improve the frequency of anti-shake, which helps to realize high frame rate clear imaging.

[0129] In one specific example, the mover fixing portion 721 is fixed to the top surface of the anti-shake carrier 21, and the stator fixing portion 722 is fixed to the top surface of the base 11.

[0130] It is worth mentioning that when the driving assembly 30 drives the anti-shake carrier 21 to move (i.e., translate) relative to the base 11 in the horizontal direction perpendicular to the optical axis Z (the combination of the first axis direction D1 and the second axis direction D2), the three anti-shake support portions 41 and the corresponding ball grooves in the anti-shake support portions 41 in the present application cannot provide a guiding effect, so that the anti-shake carrier 21 has the risk of rotating relative to the base 11 around the optical axis Z. The rotation of the anti-shake carrier 21 around the optical axis Z is an adverse action in the anti-shake process of the motor 1, which can cause image blur, and the elastic connecting portion 723 has elasticity in the horizontal direction, which can prevent the anti-shake carrier 21 from rotating relative to the base 11 around the optical axis Z, thereby reducing the risk of image blur.

[0131] Further, the elastic connecting portion 723 is arranged above the anti-shake carrier 21, and the elastic connecting portion 723 is adapted to extend in a bent shape above the anti-shake carrier 21. On the one hand, the top of the motor 1 has a large area to accommodate the elastic connecting portion 723, and there is enough space to adapt to the shape design of the elastic connecting portion 723; on the other hand, due to the flat characteristic of the elastic circuit board 72, the flat elastic connecting portion 723 has little effect on the overall height of the motor 1. Accordingly, the size of the elastic connecting portion 723 in the horizontal direction is greater than its size in the optical axis direction D.

[0132] It can be understood that since the focusing carrier 22 is further arranged in the anti-shake carrier 21 in some cases, and the focusing carrier 22 moves upward (i.e., to the object side) relative to the anti-shake carrier 21 along the optical axis Z, it is preferred to avoid the motion of the focusing carrier 22 interfering with the elastic connecting portion 723 to prevent the elastic connecting portion 723 from interfering with the movement of the focusing carrier 22. Accordingly, in the optical axis direction D, the elastic connecting portion 723 and the focusing carrier 22 do not overlap; that is, the elastic connecting portion 723 and the focusing carrier 22 are arranged in the first axis direction D1 and the second axis direction D2.

[0133] In particular, the mover fixing part 721 comprises a first mover fixing end 7211, the elastic connecting part 723 comprises a first elastic connecting piece 7231, and the stator fixing part 722 comprises a first stator fixing end 7221. The first mover fixing end 7211 is fixed to the top surface of the anti-shake carrier 21, the first stator fixing end 7221 is fixed to the top surface of the base 11, and the first elastic connecting piece 7231 is connected between the first mover fixing end 7211 and the first stator fixing end 7221, so that the first elastic connecting piece 7231 is adapted to be suspended above the anti-shake carrier 21.

[0134] In an embodiment of the present application, the first mover fixing end 7211 has an opening, the anti-shake carrier 21 has a protrusion corresponding to the opening of the first mover fixing end 7211, and the protrusion corresponding to the opening of the first mover fixing end 7211 on the anti-shake carrier 21 extends into the opening of the first mover fixing end 7211, so that the first mover fixing end 7211 is fixed to the anti-shake carrier 21. In this way, the opening of the first mover fixing end 7211 and the protrusion corresponding to the opening of the first mover fixing end 7211 on the anti-shake carrier 21 play a positioning role, so that the position of the first mover fixing end 7211 is accurately fixed. It should be understood that the first mover fixing end 7211 and the anti-shake carrier 21 can be fixed by glue, and can also be fixed by riveting or laser welding.

[0135] The first stator fixing end 7221 and the base 11 can also be fixed by glue, or by riveting or laser welding.

[0136] More specifically, the first mover fixing end 7211 is fixed to the top surface of the fourth anti-shake side wall 214, and the first stator fixing end 7221 is fixed to the top surface of the first base side wall 112 of the base 11. By designing the height of the first base side wall 112 and the fourth anti-shake side wall 214, the height of the first mover fixing end 7211 and the first stator fixing end 7221 can be adjusted.

[0137] It should be appreciated that in the optical axis direction D, the height of the first mover fixed end 7211 can be higher than, flush with, or lower than the height of the first stator fixed end 7221, as long as the first elastic connecting member 7231 is suspended above the anti-vibration carrier 21. Preferably, the height of the first mover fixed end 7211 is flush with the height of the first stator fixed end 7221, so that the first elastic connecting member 7231 can extend at the same height as much as possible, reducing the influence of the first elastic connecting member 7231 in the optical axis direction D (deformation in the optical axis direction D will generate a certain elastic force in the optical axis direction D). Of course, the force in the optical axis direction D can also be used to press down the anti-vibration carrier 21, so that the anti-vibration carrier 21 is more stably held on the base 11. At this time, the height of the first mover fixed end 7211 is higher than the height of the first stator fixed end 7221, so that the first mover fixed end 7211 will exert a downward elastic force on the anti-vibration carrier 21.

[0138] In an example of the present application, the part of the top surface of the anti-vibration carrier 21 for fixing the elastic circuit board 72 is raised, so that the elastic connecting part 723 can be suspended above the anti-vibration carrier 21. Specifically, as shown in FIG. 7, the top surface of the part of the anti-vibration carrier 21 where the first mover fixed end 7211 is mounted is higher than the top surface of the part of the anti-vibration carrier 21 corresponding to the first elastic connecting member 7231, so that the first elastic connecting part 723 is suspended above the anti-vibration carrier 21. Figure 6

[0139] Further, the fixing position of the first mover fixed end 7211 and the anti-vibration carrier 21 is arranged close to the center of gravity of the anti-vibration carrier 21 and the components carried thereby, which helps to improve the stability of the motor 1 and increase the anti-rotation ability of the anti-vibration carrier 21 when translating relative to the base 11.

[0140] Specifically, in the present application, the first mover fixed end 7211 is located at the middle of the side wall of the anti-vibration carrier 21 where it is located. Specifically, along the first axis direction D1, the fixing position of the first mover fixed end 7211 and the anti-vibration carrier 21 is located at the middle of the fourth anti-vibration side wall 214. Quantitatively, the fixing position of the first mover fixed end 7211 and the anti-vibration carrier 21 is located at 1 / 3 to 2 / 3 of the fourth anti-vibration side wall 214. To be specific, the fixing position of the first mover fixed end 7211 and the anti-vibration carrier 21 is located at 1 / 3 to 2 / 3 of the dimension of the fourth anti-vibration side wall 214 in the first axis direction D1 from the end point of the fourth anti-vibration side wall 214.

[0141] ​Further, the fixed position of the first mover fixed end 7211 and the anti-vibration carrier 21 overlaps with the optical axis Z in the second axial direction D2, i.e., the orthographic projection of the fixed position of the first mover fixed end 7211 and the anti-vibration carrier 21 in the second axial direction D2 overlaps with the optical axis Z, so that the fixed position of the first mover fixed end 7211 and the anti-vibration carrier 21 is closer to the center of gravity of the anti-vibration carrier 21 and the components carried thereby. Here, the fixed position of the first mover fixed end 7211 and the anti-vibration carrier 21 is the geometric center of the first mover fixed end 7211.

[0142] Further, the first stator fixed end 7221 is located at the middle of the side wall of the base 11. Specifically, in the first axial direction D1, the fixed position of the first stator fixed end 7221 and the base 11 is located at the middle of the first base side wall 112, quantitatively, the fixed position of the first stator fixed end 7221 and the base 11 is located at the position opposite to 1 / 3 to 2 / 3 of the fourth base bottom edge 1114 of the first base side wall 112. To be specific, the fixed position of the first stator fixed end 7221 and the base 11 is located at 1 / 3 to 2 / 3 of the size of the first base side wall 112 in the first axial direction D1 from the end point of the first base side wall 112 in the first axial direction D1.

[0143] It is worth mentioning that, for the purpose of avoiding the increase of the lateral size of the motor 1, the first stator fixed end 7221 and the first mover fixed end 7211 are staggered with each other in the first axial direction D1, and the orthographic projection of the first stator fixed end 7221 and the first mover fixed end 7211 in the first axial direction D1 overlaps. In an example of the present application, the orthographic projection of the first stator fixed end 7221 and the first mover fixed end 7211 in the second axial direction D2 is staggered with each other, or the orthographic projection of the geometric center of the first stator fixed end 7221 and the geometric center of the first mover fixed end 7211 in the second axial direction D2 is staggered with each other.

[0144] In one example of the present application, the first elastic connecting member 7231 comprises two first axial extension portions 710 and two second axial extension portions 720, which are connected by bending. The two first axial extension portions 710 and the two second axial extension portions 720 make the first elastic connecting member 7231 have a relatively low influence on the translation of the anti-vibration carrier 21 relative to the base 11 in the horizontal direction, while still being able to maintain a relatively large influence on the rotation of the anti-vibration carrier 21 relative to the base 11 about the optical axis Z. The length extension direction of the first axial extension portions 710 is consistent with the first axial direction D1, and the length extension direction of the second axial extension portions 720 is consistent with the second axial direction D2.

[0145] Specifically, one of the first axial extension portions 710 of the first elastic connecting member 7231 extends between the first mover fixed end 7211 and one of the second axial extension portions 720, one of the second axial extension portions 720 extends between the first axial extension portion 710 connected to the first mover fixed end 7211 and another of the second axial extension portions 720, and another of the first axial extension portions 710 extends between the first stator fixed end 7221 and the second axial extension portion 720.

[0146] More specifically, one of the first axial extension portions 710 of the first elastic connecting member 7231 extends from the first mover fixed end 7211 along the top surface of the fourth anti-vibration side wall 214 towards the third anti-vibration side wall 213, one of the second axial extension portions 720 extends from the first axial extension portion 710 connected to the first mover fixed end 7211 along the top surface of the third anti-vibration side wall 213 towards the second anti-vibration side wall 212, and another of the second axial extension portions 720 extends from the previous second axial extension portion 720 along the top surface of the third anti-vibration side wall 213 towards the fourth anti-vibration side wall 214; and another of the first axial extension portions 710 extends from the second axial extension portion 720 to the first stator fixed end 7221 located on the fourth base side wall.

[0147] In general, the first elastic connecting member 7231 extends from the fourth side of the motor 1 along the first axis direction D1, bends 90° to extend along the second axis direction D2, bends 180° to extend along the second axis direction D2, and bends 90° to extend along the first axis direction D1, thereby connecting the first mover fixed end 7211 and the first stator fixed end 7221 on the fourth side of the motor 1. By means of the two 90° bends and the 180° bend, a part of the first elastic connecting member 7231 extends along the first axis direction D1, and the other part extends along the second axis direction D2. It can be understood that the 180° bend design makes the first elastic connecting member 7231 form a symmetrical U-shaped structure in the second axis direction D2, can uniformly disperse the stress generated by the displacement of the anti-shake carrier 21, and reduce the risk of fatigue fracture caused by stress concentration; and the 90° bend design can enhance the torsional stiffness of the first elastic connecting member 7231, and plays a role in preventing the anti-shake carrier 21 from rotating relative to the base 11.

[0148] Correspondingly, the first mover fixed end 7211 and the first stator fixed end 7221 are arranged on the same side (the fourth side) of the motor 1. On the one hand, the motor single-side space can be maximized, and fixed structures are avoided to be arranged on other sides of the motor, thereby reducing the overall size; on the other hand, the symmetry of the first elastic connecting member 7231 itself is improved.

[0149] Further, the first elastic connecting member 7231 is arranged on the same side of the first mover fixed end 7211 and the first stator fixed end 7221, so that the first elastic connecting member 7231 can have a longer extension space.

[0150] In a preferred example, the sum of the lengths of the two first axial extension portions 710 of the first elastic connecting member 7231 is equal to the sum of the lengths of the two second axial extension portions 720.

[0151] It can be understood that, due to tolerances, the sum of the lengths of the two first axial extension portions 710 of the first elastic connecting member 7231 and the sum of the lengths of the two second axial extension portions 720 allow an error of not more than 5%, that is, the sum of the lengths of the two first axial extension portions 710 of the first elastic connecting member 7231 and the sum of the lengths of the two second axial extension portions 720 are considered equal when the error is not more than 5%.

[0152] It is worth mentioning that the connection between the two second axial extension portions 720 of the first elastic connecting member 7231 is far away from the first stator fixed end 7221 and the first mover fixed end 7211, and is easy to fall without support. Based on this, in an embodiment of the present application, as shown inFigure 8 As shown, the top surface of the anti-vibration carrier 21 is provided with a support protrusion 730 at a position corresponding to the connection of the two second axially extending portions 720 of the first elastic connecting member 7231, and the connection of the two second axially extending portions 720 of the first elastic connecting member 7231 is supported by the support protrusion 730 to avoid the part of the first elastic connecting member 7231 away from the first stator fixed end 7221 and the first mover fixed end 7211 from falling down and rubbing against the anti-vibration carrier 21. The first elastic connecting member 7231 is basically suspended above the anti-vibration carrier 21 under the support of the support protrusion 730, the first stator fixed end 7221 and the first mover fixed end 7211. It should be understood that the connection of the two second axially extending portions 720 of the first elastic connecting member 7231 is arc-shaped.

[0153] The support protrusion 730 can be formed on the top surface of the anti-vibration carrier 21 by means of integral molding, bonding components or directly applying glue. Preferably, the support protrusion 730 is formed by directly applying glue, i.e. the hardened glue forms the support protrusion 730. On the one hand, the height of the support protrusion 730 formed by directly applying glue can be controlled to be relatively low, and on the other hand, when a plurality of support protrusions 730 are provided, it is also helpful to keep the consistency of the plurality of support protrusions 730, and the surface of the support protrusion 730 formed by the hardened glue is generally smoother and has smaller friction. Moreover, the support protrusion 730 formed by the hardened glue has a certain elasticity and can play a certain role in vibration reduction and deformation buffering. The glue is preferably UV (ultraviolet) curing glue.

[0154] Further, the elastic coefficient (K value) of the first elastic connecting member 7231 in the horizontal direction is greater than or equal to the weight of the driving part / 0.1 mm, wherein the weight of the driving part refers to the sum of the weight of the anti-vibration carrier 21 and the weight of other components carried by the anti-vibration carrier 21. In a specific example, the elastic coefficient (K value) of the first elastic connecting member 7231 in the horizontal direction is greater than or equal to 50 mN / mm.

[0155] In an embodiment of the present application, as shown in Figure 7As shown, each of the elastic connecting parts 723 includes at least two (e.g. two, three or four or more) conductive wires 740. The elastic connecting part further includes an insulating layer 750 covering the conductive wires 740 and a glue for bonding the conductive wires 740 and the insulating layer 750. The insulating layer 750 and the glue can enhance the structural strength of the elastic connecting part 723. In one example, the insulating layer 750 can be formed of a polyimide film. It is worth mentioning that each of the conductive wires 740 is arranged in parallel with each other, more specifically, each of the conductive wires 740 is arranged in parallel with each other in the height direction and / or the horizontal direction. It is to be understood that although the first elastic connecting part 7231 and the second elastic connecting part 7232 can each include at least two conductive wires 740, only the first elastic connecting part 7231 or the second elastic connecting part 7232 described below can be used for electrical conduction, for example, in one example, only the first elastic connecting part 7231 is used for electrical conduction. Of course, in other examples, the first elastic connecting part 7231 and the second elastic connecting part 7232 can be used for electrical conduction at the same time.

[0156] It is to be understood that the application uses the elastic circuit board 72 for the shake suppression of the anti-shake carrier 21 and / or the reset of the anti-shake carrier 21, in order to increase the elastic coefficient of the elastic connecting part 723 of the elastic circuit board 72, the thickness of the polyimide film can be increased or the composition of the polyimide film can be optimized, or the mechanical strength and stability can be improved by increasing the reinforcing layer.

[0157] Further, the focusing coil 322 and / or the focusing sensing element 61 are electrically connected to the stator fixing part 721, and then the focusing coil 322 and / or the focusing sensing element 61 are electrically connected to other components (e.g. the photosensitive assembly 3) of the camera module through the elastic circuit board 72.

[0158] Correspondingly, the stator fixing part 721 further includes the focusing conductive part 7212. The focusing conductive part 7212 is connected to the first stator fixing end 7211, and the focusing coil 322 and / or the focusing sensing element 61 are electrically connected to the focusing conductive part 7212. It is to be understood that the focusing conductive part 7212 is electrically connected to the first stator fixing end 7211, and the conductive wires 740 extend to the focusing conductive part 7212 via the first stator fixing end 7211.

[0159] In particular, the focusing conductive member 7212 is fixed to the sidewall (e.g., the first anti-shake sidewall 211) of the anti-shake carrier 21, the focusing coil 322 and / or the focusing sensing element 61 are fixed to the side of the focusing conductive member 7212 facing the focusing magnet 321, and the sidewall (e.g., the first anti-shake sidewall 211) of the anti-shake carrier 21 has an opening corresponding to the position of the focusing coil 322 and / or the focusing sensing element 61 for accommodating the focusing coil 322 and / or the focusing sensing element 61. The focusing magnetic attraction member 52 is fixed to the side of the focusing conductive member 7212 away from the focusing magnet 321, so that the focusing coil 322, the focusing sensing element 61, and the focusing magnetic attraction member 52 are fixed to the anti-shake carrier 21 through the focusing conductive member 7212.

[0160] Further, the focusing conductive member 7212 includes a vertical extension portion 72121 and a first horizontal extension portion 72122. The focusing magnetic attraction member 52, the focusing coil 322, and / or the focusing sensing element 61 are fixed to the vertical extension portion 72121, the focusing conductive member 7212 is fixed to the sidewall (e.g., the first anti-shake sidewall 211) of the anti-shake carrier 21 through the vertical extension portion 72121, and one end of the first horizontal extension portion 72122 is connected to the vertical extension portion 72121 by bending, and the other end of the first horizontal extension portion 72122 is connected to the first mover fixing end 7211.

[0161] It should be understood that, in some examples, the first horizontal extension portion 72122 and the vertical extension portion 72121 are two separate parts, and one end of the first horizontal extension portion 72122 is fixed and electrically connected to the vertical extension portion 72121 by welding.

[0162] It is worth mentioning that the first horizontal extension portion 72122 extends between the vertical extension portion 72121 and the first elastic connecting member 7231, so that the focusing conductive member 7212 is integrally connected with the elastic connecting portion 723 and the stator fixing portion 722, thereby facilitating installation.

[0163] The stator fixing portion 722 further comprises a stator leading-out piece 7222. The stator leading-out piece 7222 is connected with the first stator fixing end 7221. Specifically, the stator leading-out piece 7222 is bent and connected with the first stator fixing end 7221 and attached to the outside of the first base side wall 112. The stator leading-out piece 7222 is used to electrically connect with other components of the camera module (for example, the photosensitive assembly 3). It should be understood that the stator leading-out piece 7222 is electrically connected with the first stator fixing end 7221, and the conductive wire 740 extends to the stator leading-out piece 7222 via the first stator fixing end 7221.

[0164] It is worth mentioning that the stator leading-out piece 7222 itself extends to the outside of the base side wall, and does not need to be connected with the base circuit board 71 or the base conductive insert 73 to achieve electrical connection with other components of the camera module (for example, the photosensitive assembly 3).

[0165] Further, in some embodiments of the present application, the rotor fixing portion 721 comprises a second rotor fixing end 7213, the elastic connecting portion 723 further comprises a second elastic connecting piece 7232, and the stator fixing portion 722 further comprises a second stator fixing end 7223. The second rotor fixing end 7213 is fixed to the top surface of the anti-shake carrier 21, the second stator fixing end 7223 is fixed to the top surface of the base 11, and the second elastic connecting piece 7232 is connected between the second rotor fixing end 7213 and the second stator fixing end 7223, so that the second elastic connecting piece 7232 is adapted to be suspended above the anti-shake carrier 21.

[0166] In an embodiment of the present application, the second rotor fixing end 7213 has an opening, and the anti-shake carrier 21 has a protrusion corresponding to the opening of the second rotor fixing end 7213. The protrusion of the anti-shake carrier 21 corresponding to the opening of the second rotor fixing end 7213 extends into the opening of the second rotor fixing end 7213, so that the second rotor fixing end 7213 is fixed to the anti-shake carrier 21. In this way, the opening of the second rotor fixing end 7213 and the protrusion of the anti-shake carrier 21 corresponding to the opening of the second rotor fixing end 7213 play a positioning role, so that the position of the second rotor fixing end 7213 is accurately fixed. It should be understood that the second rotor fixing end 7213 and the anti-shake carrier 21 can be fixed by glue, and can also be fixed by riveting or laser welding.

[0167] The second stator fixing end 7223 and the base 11 can also be fixed by glue, or by riveting or laser welding.

[0168] More specifically, the second mover fixed end 7213 is fixed on the top surface of the second anti-shake side wall 212; the second stator fixed end 7223 is fixed on the top surface of the second base side wall 113 of the base 11. By the height design of the second base side wall 113 and the second anti-shake side wall 212, the height of the second mover fixed end 7213 and the second stator fixed end 7223 can be adjusted.

[0169] It can be understood that in the optical axis direction D, the height of the second mover fixed end 7213 can be higher than, flush with, or lower than the height of the second stator fixed end 7223, as long as the second elastic connecting piece 7232 is suspended above the anti-shake carrier 21. Preferably, the height of the second mover fixed end 7213 is flush with the height of the second stator fixed end 7223, so that the second elastic connecting piece 7232 can extend at the same height as much as possible, reducing the influence of the second elastic connecting piece 7232 in the optical axis direction D (deformation in the optical axis direction D will generate a certain elastic force in the optical axis direction D). Of course, the force in the optical axis direction D can also be used to press down the anti-shake carrier 21, so that the anti-shake carrier 21 is more stably held on the base 11. At this time, the height of the second mover fixed end 7213 is higher than the height of the second stator fixed end 7223, so that the second mover fixed end 7213 will exert a downward elastic force on the anti-shake carrier 21.

[0170] The top surface of the anti-shake carrier 21 where the second mover fixed end 7213 is mounted is higher than the top surface of the anti-shake carrier 21 corresponding to the second elastic connecting piece 7232, so that the second elastic connecting part 723 is suspended above the anti-shake carrier 21.

[0171] Further, the fixed position of the second mover fixed end 7213 and the anti-shake carrier 21 is set close to the center of gravity of the anti-shake carrier 21 and the components carried thereby, which helps to improve the stability of the motor 1 and increase the anti-rotation ability of the anti-shake carrier 21 when translating relative to the base 11.

[0172] Specifically, in the present application, along the first axial direction D1, the fixed position of the second mover fixed end 7213 and the anti-vibration carrier 21 is located in the middle of the second anti-vibration side wall 212, quantitatively, the fixed position of the second mover fixed end 7213 and the anti-vibration carrier 21 is located at 1 / 3 to 2 / 3 of the second anti-vibration side wall 212. To be specific, the fixed position of the second mover fixed end 7213 and the anti-vibration carrier 21 is located at 1 / 3 to 2 / 3 of the size of the second anti-vibration side wall 212 in the first axial direction D1 from the end point of the second anti-vibration side wall 212.

[0173] Further, as viewed along the second axial direction D2, the fixed position of the second mover fixed end 7213 and the anti-vibration carrier 21 overlaps the optical axis Z, that is, the orthogonal projection of the fixed position of the second mover fixed end 7213 and the anti-vibration carrier 21 in the second axial direction D2 overlaps the optical axis Z, so that the fixed position of the second mover fixed end 7213 and the anti-vibration carrier 21 is closer to the center of gravity of the anti-vibration carrier 21 and the components carried thereby. Here, the fixed position of the second mover fixed end 7213 and the anti-vibration carrier 21 is the geometric center of the second mover fixed end 7213.

[0174] Further, along the first axial direction D1, the fixed position of the second stator fixed end 7223 and the base 11 is located in the middle of the second base side wall 113, quantitatively, the fixed position of the second stator fixed end 7223 and the base 11 is located at 1 / 3 to 2 / 3 of the first base side wall 112 opposite to the fourth base bottom edge 1114. To be specific, the fixed position of the second stator fixed end 7223 and the base 11 is located at 1 / 3 to 2 / 3 of the size of the second base side wall 113 in the first axial direction D1 from the end point of the second base side wall 113.

[0175] It is worth mentioning that, for the purpose of avoiding the increase of the lateral size of the motor 1, the second stator fixed end 7223 and the second mover fixed end 7213 are staggered with each other in the first axial direction D1, and the orthogonal projection of the second stator fixed end 7223 and the second mover fixed end 7213 in the first axial direction D1 overlaps. In one example of the present application, the orthogonal projection of the second stator fixed end 7223 and the second mover fixed end 7213 in the second axial direction D2 is staggered with each other, or the orthogonal projection of the geometric center of the second stator fixed end 7223 and the geometric center of the second mover fixed end 7213 in the second axial direction D2 is staggered with each other.

[0176] In one example of the present application, the second elastic connecting member 7232 comprises two first axial extension portions 710 and two second axial extension portions 720, which are connected by bending. The two first axial extension portions 710 and the two second axial extension portions 720 make the second elastic connecting member 7232 have a lower influence on the translation of the anti-vibration carrier 21 relative to the base 11 in the horizontal direction, while still being able to maintain a greater influence on the rotation of the anti-vibration carrier 21 relative to the base 11 about the optical axis Z. The length extension direction of the first axial extension portion 710 is consistent with the first axial direction D1, and the length extension direction of the second axial extension portion 720 is consistent with the second axial direction D2.

[0177] Specifically, one of the first axial extension portions 710 of the second elastic connecting member 7232 extends between the second mover fixed end 7213 and one of the second axial extension portions 720, one of the second axial extension portions 720 extends between the first axial extension portion 710 connected to the second mover fixed end 7213 and another of the second axial extension portions 720, and another of the first axial extension portions 710 extends between the second stator fixed end 7223 and the second axial extension portion 720.

[0178] More specifically, one of the first axial extension portions 710 of the second elastic connecting member 7232 extends from the second mover fixed end 7213 along the top surface of the second anti-vibration side wall 212 to the third anti-vibration side wall 213, one of the second axial extension portions 720 extends from the first axial extension portion 710 connected to the second mover fixed end 7213 along the top surface of the third anti-vibration side wall 213 to the fourth anti-vibration side wall 214, and another of the second axial extension portions 720 extends from the previous second axial extension portion 720 along the top surface of the third anti-vibration side wall 213 to the second anti-vibration side wall 212; and another of the first axial extension portions 710 extends from the second axial extension portion 720 to the second stator fixed end 7223 located on the second base side wall 113.

[0179] Overall, the second elastic connecting piece 7232 extends from the second side of the motor 1 along the first axial direction D1, bends 90° to extend along the second axial direction D2, bends 180° to extend along the second axial direction D2, and finally bends 90° to extend along the first axial direction D1, thereby connecting the second mover fixed end 7213 and the second stator fixed end 7223 located on the second side of the motor 1. By means of two 90° bends and one 180° bend, a part of the second elastic connecting piece 7232 extends along the first axial direction D1, and the other part extends along the second axial direction D2. It can be understood that the design of the 180° bend makes the second elastic connecting piece 7232 form a symmetrical U-shaped structure in the second axial direction D2, can uniformly disperse the stress generated by the displacement of the anti-shake carrier 21, and reduce the risk of fatigue fracture caused by stress concentration; and the design of the 90° bend can enhance the torsional stiffness of the second elastic connecting piece 7232, and plays a role in preventing the anti-shake carrier 21 from rotating relative to the base 11.

[0180] Correspondingly, the second mover fixed end 7213 and the second stator fixed end 7223 are arranged on the same side (the second side) of the motor 1. On the one hand, the motor single-side space can be maximized, and fixed structures are avoided to be arranged on the other side of the motor, thereby reducing the overall size; on the other hand, it is helpful to improve the symmetry of the first elastic connecting piece 7231 itself.

[0181] Further, the second elastic connecting piece 7232 is arranged on the same side of the second mover fixed end 7213 and the second stator fixed end 7223, so that the second elastic connecting piece 7232 can have a longer extension space.

[0182] Correspondingly, in an embodiment of the present application, the elastic connecting part 723 is arranged on the same side of the mover fixed part 721 and the stator fixed part 722.

[0183] In a preferred example, the sum of the lengths of the two first axial extension parts 710 of the second elastic connecting piece 7232 is equal to the sum of the lengths of the two second axial extension parts 720.

[0184] It can be understood that, due to tolerances, the sum of the lengths of the two first axial extension parts 710 of the second elastic connecting piece 7232 and the sum of the lengths of the two second axial extension parts 720 allow an error of not more than 5%, that is, the error between the sum of the lengths of the two first axial extension parts 710 of the second elastic connecting piece 7232 and the sum of the lengths of the two second axial extension parts 720 is not more than 5%, and it can be considered that the two are equal.

[0185] It is worth mentioning that the connection of the two second axial extension portions 720 of the second elastic connecting member 7232 is far away from the second stator fixed end 7223 and the second mover fixed end 7213, and is prone to sag without support. Based on this, in an embodiment of the present application, as shown in Figure 8 The top surface of the anti-shake carrier 21 is provided with a support protrusion 730 at a position corresponding to the connection of the two second axial extension portions 720 of the second elastic connecting member 7232, and the connection of the two second axial extension portions 720 of the second elastic connecting member 7232 is supported by the support protrusion 730 to avoid the second elastic connecting member 7232 sagging away from the second stator fixed end 7223 and the second mover fixed end 7213 and rubbing against the anti-shake carrier 21. The second elastic connecting member 7232 is basically suspended above the anti-shake carrier 21 under the support of the support protrusion 730, the second stator fixed end 7223 and the second mover fixed end 7213. It should be understood that the connection of the two second axial extension portions 720 of the second elastic connecting member 7232 is arc-shaped.

[0186] Further, the elastic coefficient (K value) of the second elastic connecting member 7232 in the horizontal direction is greater than or equal to the weight of the driving part / 0.1mm, where the weight of the driving part refers to the sum of the weight of the anti-shake carrier 21 and other components carried by the anti-shake carrier 21. In a specific example, the elastic coefficient (K value) of the second elastic connecting member 7232 in the horizontal direction is greater than or equal to 50mN / mm.

[0187] Further, the focusing conductive member 7212 further comprises a second horizontal extension portion 72123. One end of the second horizontal extension portion 72123 is connected to the vertical extension portion 72121 by bending, and the other end of the second horizontal extension portion 72123 is connected to the second mover fixed end 7213.

[0188] It is worth mentioning that the second horizontal extension portion 72123 extends between the vertical extension portion 72121 and the second elastic connecting member 7232, so that the focusing conductive member 7212 is integrally connected with the elastic connecting portion 723 and the stator fixed portion 722, thereby facilitating installation.

[0189] The first mover fixed end 7211, the first elastic connecting piece 7231 and the first stator fixed end 7221 form a first side 7210 of the elastic circuit board 72; the second mover fixed end 7213, the second elastic connecting piece 7232 and the second stator fixed end 7223 form a second side 7220 of the elastic circuit board 72. The first side 7210 and the second side 7220 of the elastic circuit board 72 are designed in axial symmetry, so that the first side 7210 and the second side 7220 of the elastic circuit board 72 are symmetrical to the reset ability of the anti-shake carrier 21, which is beneficial to reduce the shaking caused by the unbalanced force distribution, thereby maintaining the stability of the anti-shake function of the motor 1 and increasing the anti-shake precision. Most importantly, the first elastic connecting piece 7231 and the second elastic connecting piece 7232 are designed in axial symmetry.

[0190] The symmetry axis of the first side 7210 and the second side 7220 of the elastic circuit board 72 passes through the optical axis Z. It should be understood that, from the perspective of actual manufacturing, the arrangement position of the components may be considered, and there may be tolerances, so that the symmetry axis of the first side 7210 and the second side 7220 of the elastic circuit board 72 does not necessarily pass through the optical axis Z, but is close to the optical axis Z.

[0191] It is worth mentioning that in other embodiments of the present application, the elastic circuit board 72 can be provided with only the first side portion 7210, i.e., only the first mover fixed end 7211, the first elastic connecting piece 7231 and the first stator fixed end 7221; the first side portion 7210 can be arranged on the second side of the motor 1. When the first side portion 7210 is arranged on the second side of the motor 1, the first mover fixed end 7211 is fixed to the top surface of the second anti-shake side wall 212; the first stator fixed end 7221 is fixed to the top surface of the second base side wall 113 of the base 11; along the first axial direction D1, the fixed positions of the first mover fixed end 7211 and the first stator fixed end 7221 on the anti-shake carrier 21 and the base 11 are located in the middle of the second anti-shake side wall 212 and the second base side wall 113 respectively; one of the first axial extension portions 710 of the first elastic connecting piece 7231 extends from the second mover fixed end 7213 along the top surface of the second anti-shake side wall 212 to the third anti-shake side wall 213, one of the second axial extension portions 720 extends from the first axial extension portion 710 connected to the second mover fixed end 7213 along the top surface of the third anti-shake side wall 213 to the fourth anti-shake side wall 214, and another second axial extension portion 720 extends from the previous second axial extension portion 720 along the top surface of the third anti-shake side wall 213 to the second anti-shake side wall 212; the other first axial extension portion 710 extends from the second axial extension portion 720 to the second stator fixed end 7223 located on the second base side wall 113; the first elastic connecting piece 7231 extends along the first axial direction D1 from the second side of the motor 1, bends by 90° and then extends along the second axial direction D2, bends by 180° and then extends along the second axial direction D2, and finally bends by 90° and then extends along the first axial direction D1, so as to connect the first mover fixed end 7211 and the first stator fixed end 7221 located on the second side of the motor 1; the stator leading-out piece 7222 is attached to the outer side of the second base side wall 113.

[0192] It is worth mentioning that in an embodiment of the present application, as Figure 9 and Figure 10As shown, the motor 1 further comprises a first bending retaining member 81 and a second bending retaining member 82. The first bending retaining member 81 is arranged outside the first stator fixed end 7221, extends in a vertical direction, and can extend to outside the stator leading-out member 7222. The first bending retaining member 81 is bent in a horizontal direction relative to the part extending in the vertical direction, and can maintain the bending state between the first stator fixed end 7221 and the stator leading-out member 7222 to a certain extent, so as to prevent the first stator fixed end 7221 from being upwardly warped and the first elastic connecting member 7231 from being upwardly warped, or the stator leading-out member 7222 from being outwardly warped. The second bending retaining member 82 is arranged outside the second stator fixed end 7223, extends in a vertical direction, and is bent in a horizontal direction relative to the part extending in the vertical direction. The second bending retaining member 82 can apply pressure to the second stator fixed end 7223 to a certain extent, so as to prevent the second stator fixed end 7223 from being upwardly warped and the second elastic connecting member 7232 from being upwardly warped.

[0193] In addition, the first bending retaining member 81 and the second bending retaining member 82 can also improve the reset capability of the elastic circuit board 72 in the second axial direction D2.

[0194] In summary, the camera module and the motor 1 used in the camera module according to the embodiments of the present application are illustrated. The motor 1 can suppress the rotation of the anti-shake carrier 21 around the optical axis Z by the elasticity of the elastic circuit board 72, and provide reset capability.
