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] The camera module is an indispensable component in electronic devices such as mobile phones and tablets, which is used to meet the shooting requirements. 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 the motor to drive the lens assembly to move.

[0003] With the increasing demand of consumers for shooting quality, the anti-shake performance of the camera module becomes more and more critical. For example, during video shooting, the shaking of the device will cause the picture to be blurred, which seriously reduces the shooting effect of the video. Especially in the long-focus shooting mode, even a slight shaking of the device 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.

[0005] In addition, miniaturization and thinning are inevitable trends in electronic devices such as mobile phones and tablets.

Detailed Implementation

[0072] 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.

[0073] The camera module needs to meet the requirement of small volume, and also needs to meet the requirement of various functions such as optical image stabilization and auto focusing. In order to meet the requirement of various functions such as optical image stabilization and auto focusing, corresponding components need to be configured. In theory, the components will be more and more, the structure of the camera module will become more and more complex, and the overall size and overall weight of the camera module are also difficult to control within a certain range, which is contrary to the requirement of small volume of the camera module.

[0074] As shown in Figures 1 to 14 and Figures 15 to 22 , the camera module and the motor 10 for the camera module according to the embodiments of the present application are illustrated.

[0075] Specifically, as shown in Figure 14 , the camera module includes a lens assembly 20, a motor 10 and a photosensitive assembly 30. The motor 10 is mounted on the photosensitive assembly 30. The lens assembly 20 is mounted on the motor 10 and located on the photosensitive path of the photosensitive assembly 30; the lens assembly 20 defines an optical axis L and an optical axis direction D. The optical axis direction D of the lens assembly 20 is the length extension direction of the optical axis L. The height direction of the camera module and the height direction of the motor 10 are consistent with the optical axis direction D. The motor 10 is used to drive the lens assembly 20 to move to realize the functions of auto focusing and optical image stabilization.

[0076] The photosensitive assembly 30 includes a chip circuit board, a photosensitive chip and at least one electronic component. The photosensitive surface of the photosensitive chip faces the lens assembly 20 to receive light rays emitted from the lens assembly 20. In one specific example, the photosensitive chip is fixed to one side of the chip circuit board facing the lens assembly 20. At least one of the electronic components can be implemented as passive electronic devices such as capacitors and resistors, or active electronic devices such as diodes and memory chips, and at least one of the electronic components can be arranged on one side of the chip circuit board facing the lens assembly 20. In one specific example, the photosensitive chip is electrically connected to the chip circuit board through at least one lead wire.

[0077] In some examples of the present application, the camera module further comprises a filter assembly arranged on the light path of the photosensitive assembly 30, so that the camera module can filter out unnecessary stray light (e.g. infrared light) through the filter assembly. For example, the filter assembly is arranged between the lens assembly 20 and the photosensitive assembly 30. In one specific example, the filter assembly comprises a bracket and a filter element. The bracket is supported on the chip circuit board, and the filter element is fixed on the bracket.

[0078] The motor 10 has four sides, in which, in the present application, the four sides of the motor 10 are defined as the first side, the second side, the third side and the fourth side in counterclockwise. Accordingly, the four sides of each component of the motor 10 are consistent with the four sides of the motor 10. The optical axis of the motor 10 is consistent with the optical axis L of the lens assembly 20; the direction of the optical axis of the motor 10 is consistent with the direction D of the optical axis defined by the lens assembly 20. In the present application, two mutually perpendicular axes perpendicular to the optical axis L are defined as the first axis and the second axis; the length extension direction of the first axis is the first axis direction D1; the length extension direction of the second axis 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, and the first axis direction D1 and the second axis direction D2 are perpendicular to each other.

[0079] The motor 10 comprises a fixed assembly 11, a movable assembly 12, a driving assembly 13, a supporting assembly 14, a magnetic attraction assembly 15, a sensing assembly 16 and a conductive assembly 17. The movable assembly 12 is used to carry the lens assembly 20 and is movably arranged in the fixed assembly 11. The driving assembly 13 is used to drive the movement of the movable assembly 12 relative to the fixed assembly 11. The supporting assembly 14 is used to support and guide the components in the movable assembly 12. The magnetic attraction assembly 15 is used to attract the components in the movable assembly 12 to ensure the stability of their movement. The sensing assembly 16 is used to obtain the position change information of the components in the movable assembly 12. The conductive assembly 17 is connected to the driving assembly 13, and is used to realize the electrical conduction of the driving assembly 13.

[0080] In one embodiment of the present application, as shown in Figure 1 and Figure 2 The fixed assembly 11 comprises a base 111 and an upper cover 112, wherein the upper cover 112 and the base 111 are buckled and fixed to each other to form a containing cavity 101 between the base 111 and the upper cover 112. The containing cavity 101 is used to accommodate other elements. The base 111 and the movable assembly 12 form a carrier assembly 110, which is used to carry the lens assembly 20.

[0081] In this embodiment, the base 111 includes a base body 1111 and three base side walls respectively extending upwardly from three sides of the base body 1111. The base body 1111 is mainly used to provide bottom support. The base body 1111 has a base through hole 109 to allow light passing through the lens assembly 20 to enter the photosensitive assembly 30. The three base side walls are respectively a first base side wall 1112, a second base side wall 1113 and a third base side wall 1114. The first base side wall 1112, the second base side wall 1113 and the third base side wall 1114 are respectively located at a first side, a second side and a third side of the motor 10. The first base side wall 1112 and the third base side wall 1114 are oppositely arranged and respectively located at two sides of the second base side wall 1113. Specifically, the first base side wall 1112 and the third base side wall 1114 are opposite in the second axial direction D2.

[0082] It is worth mentioning that, in the present application, the base 111 is not provided with a side wall at a fourth side, which can reduce the lateral dimension of the motor 10 to a certain extent.

[0083] The movable assembly 12 includes an anti-shake carrier 121 and a focusing carrier 123. The anti-shake carrier 121 is movably mounted in the accommodating cavity 101 of the fixed assembly 11. More specifically, the anti-shake carrier 121 is movably mounted in the base 111. The anti-shake carrier 121 is configured to be adapted to move relative to the fixed assembly 11 along the first axial direction D1 and the second axial direction D2 and to move the focusing carrier 123 along the first axial direction D1 and the second axial direction D2. The focusing carrier 123 is movably mounted in the anti-shake carrier 121 and is configured to mount the lens assembly 20 therein. In other words, the lens assembly 20 is fixed to the focusing carrier 123; the anti-shake carrier 121 indirectly carries the lens assembly 20 through the focusing carrier 123; and the focusing carrier 123 moves together with the anti-shake carrier 121 relative to the base 111 along a direction perpendicular to the optical axis. The focusing carrier 123 is also configured to be adapted to move relative to the anti-shake carrier 121 along the set optical axis direction D.

[0084] In an embodiment of the present application, as Figure 2As shown, the moving assembly 12 further comprises a frame 122 disposed between the anti-shake carrier 121 and the base 111. The frame 122 and the anti-shake carrier 121 are adapted to move relative to the base 111 along a first axis direction D1 perpendicular to the optical axis, and to drive the focusing carrier 123 and the lens assembly 20 to move relative to the base 111 along the first axis direction D1 perpendicular to the optical axis. The anti-shake carrier 121 is adapted to move relative to the frame 122 along a second axis direction D2 perpendicular to the optical axis, and to drive the focusing carrier 123 and the lens assembly 20 to move relative to the base 111 along the second axis direction D2 perpendicular to the optical axis. The frame 122 is disposed in such a way that the movement of the anti-shake carrier 121 relative to the base 111 is decomposed into two perpendicular directions, thereby reducing the risk of the anti-shake carrier 121 rotating around the optical axis relative to the base 111, and achieving more accurate anti-shake function.

[0085] It should be understood that in other embodiments of the present application, the anti-shake carrier 121 can be designed to move relative to the frame 122 and the base 111 along a first axis direction D1 perpendicular to the optical axis, and to drive the focusing carrier 123 and the lens assembly 20 to move relative to the frame 122 and the base 111 along the first axis direction D1 perpendicular to the optical axis; and the anti-shake carrier 121 and the frame 122 can be adapted to move relative to the base 111 along a second axis direction D2 perpendicular to the optical axis, and to drive the focusing carrier 123 and the lens assembly 20 to move relative to the base 111 along the second axis direction D2 perpendicular to the optical axis.

[0086] In an embodiment of the present application, at least part of the frame 122 is accommodated in the anti-shake carrier 121, so as to reduce the additional height space occupied by the frame 122, and thereby to reduce the height dimension of the camera module to a certain extent. Specifically, the anti-shake carrier 121 has a lower accommodation groove 1213 recessed upward from the bottom surface of the anti-shake carrier 121. At least part of the frame 122 is accommodated in the lower accommodation groove 1213. In one example of the present application, the bottom surface of the frame 122 does not exceed the bottom surface of the anti-shake carrier 121, which is structurally manifested as that the bottom surface of the frame 122 is flush with or higher than the bottom surface of the anti-shake carrier 121.

[0087] It is worth mentioning that the size of the camera module in the height direction has a great influence on the camera module, therefore, any design that can reduce the height of the camera module is crucial to the application of the camera module. For example, the camera module can be applied to a mobile phone, and when the camera module is installed in the mobile phone, the height direction of the camera module is consistent with the thickness direction of the mobile phone. With the market demand for thin and light mobile phones, the thickness of the mobile phone is becoming thinner and thinner, about 0.5 cm, and the height space that can be reserved for the camera module is extremely limited, therefore, the height size of the camera module should be reduced as much as possible when designing the camera module.

[0088] It should also be understood that in other embodiments of the present application, the movable assembly 12 can not include the frame 122, and the anti-shake carrier 121 is directly mounted to the base 111.

[0089] The driving assembly 13 is configured to drive the focusing carrier 123 to move relative to the anti-shake carrier 121 along the optical axis direction D, and to drive the anti-shake carrier 121 to move relative to the base 111 along a direction perpendicular to the optical axis direction D.

[0090] Accordingly, in an embodiment of the present application, as shown in Figure 2 The driving assembly 13 includes an anti-shake driving assembly 1310 and a focusing driving assembly 1320. The anti-shake driving assembly 1310 is configured to drive the anti-shake carrier 121 to move relative to the fixed assembly 11 along the first axis direction D1 and the second axis direction D2, and to drive the focusing carrier 123 and the lens assembly 20 to move along the first axis direction D1 and the second axis direction D2 through the anti-shake carrier 121, so as to perform optical anti-shake. The focusing driving assembly 1320 is configured to drive the focusing carrier 123 to move relative to the anti-shake carrier 121 along the optical axis direction D, and to drive the lens assembly 20 to move relative to the anti-shake carrier 121 along the optical axis direction D, so as to perform automatic focusing. It is worth mentioning that in some embodiments, the focusing carrier 123 is fixed with all the optical lenses of the lens assembly 20, thereby realizing the optical focusing function; in other embodiments, the focusing carrier 123 is only fixed with part of the optical lenses of the lens assembly 20, and by changing the focal length of the lens assembly 20, the focal plane of the lens assembly 20 is made to coincide with the photosensitive surface of the photosensitive assembly 30, thereby realizing the optical focusing function.

[0091] Further, in an embodiment of the present application, the anti-shake driving assembly 1310 is configured to drive the anti-shake carrier 121 to move relative to the fixed assembly 11 along the first axis direction D1, thereby driving the frame 122, the focus carrier 123 and the lens assembly 20 to move along the first axis direction D1; and is configured to drive the anti-shake carrier 121 to move relative to the frame 122 and the fixed assembly 11 along the second axis direction D2, thereby driving the focus carrier 123 and the lens assembly 20 to move along the second axis direction D2.

[0092] It should be understood that, in other embodiments of the present application, the anti-shake driving assembly 1310 can be configured to drive the anti-shake carrier 121 to move relative to the frame 122 along the first axis direction D1, thereby driving the focus carrier 123 and the lens assembly 20 to move along the first axis direction D1; and is configured to drive the anti-shake carrier 121 to move relative to the fixed assembly 11 along the second axis direction D2, thereby driving the frame 122, the focus carrier 123 and the lens assembly 20 to move along the second axis direction D2.

[0093] It is worth mentioning that, in the present application, the focus driving assembly 1320 and the focus carrier 123 for performing automatic focusing are arranged inside the anti-shake driving assembly 1310 and the anti-shake carrier 121 for performing optical anti-shake, which helps to improve the automatic focusing accuracy and the component arrangement flexibility of optical anti-shake, as well as the accuracy of optical anti-shake. In the present application, the terms "inside" and "outside" are defined with respect to the optical axis of the lens assembly 20, the direction close to the optical axis is referred to as "inside", and the direction away from the optical axis is referred to as "outside".

[0094] Specifically, the focusing function has certain requirements for focusing speed and focusing accuracy. The key factor to achieve better focusing effect is to quickly and accurately adjust the position of the lens. In the present application, the focus carrier 123 for moving during automatic focusing is arranged inside the anti-shake carrier 121 for moving during optical anti-shaking. During automatic focusing, only the focus carrier 123 needs to be moved to drive the lens assembly 20 to move, which makes the focus driving assembly 1320 for performing automatic focusing need to drive a relatively small weight of components, so that the focus driving assembly 1320 for performing automatic focusing can quickly adjust the position of the lens assembly 20. Accordingly, the lens assembly 20 can respond more quickly to the driving of the focus driving assembly 1320 for performing automatic focusing, thereby achieving fast focusing.

[0095] Further, the focusing movement stroke of the lens assembly 20 is relatively large, and the focusing drive assembly 1320 for automatic focusing only needs to move the focusing carrier 123 to drive the lens assembly 20, which helps to realize the long movement stroke of the lens assembly 20. Further, benefiting from the relatively small weight of the components driven by the focusing drive assembly 1320, the focusing drive assembly 1320 can more accurately control the movement of the lens assembly 20, which helps to improve the focusing accuracy.

[0096] The optical image stabilization drive assembly 1310 for optical image stabilization can be designed to be arranged around the outer periphery of the image stabilization carrier 121, which makes the arrangement of the optical image stabilization drive assembly 1310 for optical image stabilization more flexible. And the image stabilization movement stroke is smaller than the focusing movement stroke, and the optical image stabilization drive assembly 1310 for optical image stabilization can more easily control the movement of the lens assembly 20, which helps to improve the optical image stabilization accuracy and reduce the overcompensation or undercompensation.

[0097] The image stabilization drive assembly 1310 is mounted on the outer side of the image stabilization carrier 121. Specifically, the image stabilization drive assembly 1310 is mounted between the image stabilization carrier 121 and the base 111. The focusing drive assembly 1320 is mounted on the outer side of the focusing carrier 123. Specifically, the focusing drive assembly 1320 is mounted between the focusing carrier 123 and the image stabilization carrier 121 or between the focusing carrier 123 and the base 111.

[0098] In the embodiments of the present application, the driving of the image stabilization carrier 121, the frame 122 and the focusing carrier 123 is realized by the cooperation of magnets and coils. Accordingly, as shown in Figure 2 、 Figure 12 and Figure 13 , the image stabilization drive assembly 1310 includes a first image stabilization coil 132, a first image stabilization magnet 131, a second image stabilization coil 134 and a second image stabilization magnet 133. In the present application, the first axis direction D1 is defined as the direction in which the first image stabilization coil 132 and the first image stabilization magnet 131 are oppositely arranged, and the second axis direction D2 is defined as the direction in which the second image stabilization coil 134 and the second image stabilization magnet 133 are oppositely arranged.

[0099] Accordingly, in an embodiment of the present application, as shown in Figure 2 and Figure 13As shown, the first anti-shake coil 132 and the first anti-shake magnet 131 are opposite to each other in the first axis direction D1. The first anti-shake coil 132 and the first anti-shake magnet 131 are used to drive the anti-shake carrier 121 to move relative to the base 111 along the first axis direction D1, and in turn drive the frame 122, the focus carrier 123 and the lens assembly 20 to move relative to the base 111 along the first axis direction D1 through the anti-shake carrier 121. As shown in Figure 2 and Figure 12 As shown, the second anti-shake coil 134 and the second anti-shake magnet 133 are opposite to each other in the second axis direction D2. The second anti-shake coil 134 and the second anti-shake magnet 133 are opposite to each other in the second axis direction D2 and are used to drive the anti-shake carrier 121 to move relative to the frame 122 and the base 111 along the second axis direction D2, and in turn drive the focus carrier 123 and the lens assembly 20 to move relative to the frame 122 and the base 111 along the second axis direction D2 through the anti-shake carrier 121. As shown in Figure 2 and Figure 13 As shown, the focus driving assembly 1320 includes a focus coil 136 and a focus magnet 135. In an embodiment of the present application, the focus coil 136 and the focus magnet 135 are opposite to each other in the first axis direction D1 and are used to drive the focus carrier 123 to move along the optical axis direction D.

[0100] In an embodiment of the present application, the relative arrangement direction of the first anti-shake coil 132 and the first anti-shake magnet 131 is consistent with the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132, which is the first axis direction D1; the relative arrangement direction of the second anti-shake coil 134 and the second anti-shake magnet 133 is consistent with the movement direction of the second anti-shake magnet 133 relative to the second anti-shake coil 134, which is the second axis direction D2. Accordingly, the first anti-shake magnet 131 moves relative to the first anti-shake coil 132 along the first axis direction D1; the second anti-shake magnet 133 moves relative to the second anti-shake coil 134 along the second axis direction D2.

[0101] Specifically, the focusing driving assembly 1320 is a moving magnet structure. The moving magnet structure refers to that the coil and the magnet interact, the magnet moves relative to the coil, and then drives the component fixed with the magnet to move. Specifically, the first anti-shake coil 132 and the first anti-shake magnet 131 are arranged on the second side of the anti-shake carrier 121; the second anti-shake coil 134 and the second anti-shake magnet 133 are arranged on the first side of the anti-shake carrier 121. Correspondingly, the first anti-shake coil 132 and the first anti-shake magnet 131 are located on the second side of the motor 10; the second anti-shake coil 134 and the second anti-shake magnet 133 are located on the first side of the motor 10. In an embodiment of the present application, the first anti-shake magnet 131 is fixed on the second side of the anti-shake carrier 121, and the first anti-shake coil 132 is fixed on the second base side wall 1113 of the base 111; the second anti-shake magnet 133 is fixed on the first side of the anti-shake carrier 121, and the second anti-shake coil 134 is fixed on the first base side wall 1112 of the base 111.

[0102] The first anti-shake magnet 131 has only one magnetic pole (N or S pole) facing the first anti-shake coil 132. The second anti-shake magnet 133 has only one magnetic pole (N or S pole) facing the second anti-shake coil 134. When the first anti-shake coil 132 is energized, the first anti-shake magnet 131 moves relative to the first anti-shake coil 132 along the first axis direction D1 (i.e., the relative arrangement direction of the first anti-shake coil 132 and the first anti-shake magnet 131), so as to make the first anti-shake magnet 131 approach or move away from the first anti-shake coil 132. Correspondingly, since the first anti-shake magnet 131 is fixed on the anti-shake carrier 121 and the first anti-shake coil 132 is fixed on the base 111, the anti-shake carrier 121 moves relative to the base 111 along the relative arrangement direction of the first anti-shake coil 132 and the first anti-shake magnet 131 under the driving of the first anti-shake magnet 131, and drives the frame 122 to move relative to the base 111 along the relative arrangement direction of the first anti-shake coil 132 and the first anti-shake magnet 131. When the second anti-shake coil 134 is energized, the second anti-shake magnet 133 moves relative to the second anti-shake coil 134 along the second axis direction D2 (i.e., the relative arrangement direction of the second anti-shake coil 134 and the second anti-shake magnet 133), so as to make the second anti-shake magnet 133 approach or move away from the second anti-shake coil 134. Correspondingly, since the second anti-shake magnet 133 is fixed on the anti-shake carrier 121 and the second anti-shake coil 134 is fixed on the base 111, the anti-shake carrier 121 moves relative to the frame 122 and the base 111 along the relative arrangement direction of the second anti-shake coil 134 and the second anti-shake magnet 133 under the driving of the second anti-shake magnet 133.

[0103] It should be appreciated that in other embodiments of the present application, the first anti-shake coil 132 and the first anti-shake magnet 131 can be designed to drive the anti-shake carrier 121 to move relative to the frame 122 and the base 111 along the first axis direction D1, and to drive the focusing carrier 123 and the lens assembly 20 to move along the first axis direction D1 through the anti-shake carrier 121; the second anti-shake coil 134 and the second anti-shake magnet 133 can be designed to drive the anti-shake carrier 121 to move relative to the base 111 along the second axis direction D2, and to drive the frame 122, the focusing carrier 123 and the lens assembly 20 to move relative to the base 111 along the second axis direction D2 through the anti-shake carrier 121.

[0104] When the first anti-shake coil 132 is energized, the anti-shake carrier 121 is driven by the first anti-shake magnet 131 to move relative to the base 111 and the frame 122 along the relative arrangement direction of the first anti-shake coil 132 and the first anti-shake magnet 131. When the second anti-shake coil 134 is energized, the anti-shake carrier 121 is driven by the second anti-shake magnet 133 to move relative to the base 111 along the relative arrangement direction of the second anti-shake coil 134 and the second anti-shake magnet 133, and to drive the frame 122 to move relative to the base 111 along the relative arrangement direction of the first anti-shake coil 132 and the first anti-shake magnet 131.

[0105] More specifically, the first anti-shake magnet 131 can be designed to be at least partially embedded in the anti-shake carrier 121, and / or the first anti-shake coil 132 can be designed to be at least partially embedded in the base 111, so as to reduce the transverse space occupied by the first anti-shake coil 132 and the first anti-shake magnet 131, and to reduce the transverse size of the motor 10, and to reduce the transverse size of the camera module. The second anti-shake magnet 133 can be designed to be at least partially embedded in the anti-shake carrier 121, and / or the second anti-shake coil 134 can be designed to be at least partially embedded in the base 111, so as to reduce the transverse space occupied by the second anti-shake coil 134 and the second anti-shake magnet 133, and to reduce the transverse size of the motor 10, and to reduce the transverse size of the camera module.

[0106] As Figure 15As shown, in an embodiment of the present application, the base 111 has outward protrusions 120 protruding outward relative to other portions. The outward protrusions 120 correspond to the anti-vibration coils, and the upper cover 112 avoids the outward protrusions 120 of the base 111, and does not cover the outside of the outward protrusions 120; for example, the outward protrusion 120 of the second base side wall 1113 corresponding to the first anti-vibration coil 132 protrudes from other portions of the second base side wall 1113, and protrudes from the upper cover 112. Accordingly, the upper cover 112 avoids the outward protrusion 120 of the second base side wall 1113, and does not cover the outside of the outward protrusion 120 of the second base side wall 1113. The outward protrusion 120 of the first base side wall 1112 corresponding to the second anti-vibration coil 134 protrudes from other portions of the first base side wall 1112, and protrudes from the upper cover 112. Accordingly, the upper cover 112 avoids the outward protrusion 120 of the first base side wall 1112, and does not cover the outside of the outward protrusion 120 of the first base side wall 1112, which helps to reduce the lateral dimension of the motor.

[0107] The focusing coil 136 and the focusing magnet 135 are arranged on the fourth side of the focusing carrier 123. Accordingly, the focusing coil 136 and the focusing magnet 135 are located on the fourth side of the motor 10. In an embodiment of the present application, the focusing magnet 135 is fixed to the fourth side of the focusing carrier 123, and the focusing coil 136 is fixed to the anti-vibration carrier 121.

[0108] In a variant embodiment of the present application, the focusing magnet 135 is fixed to the fourth side of the focusing carrier 123, and the focusing coil 136 is fixed to the fourth side of the base 111.

[0109] Further, the focusing magnet 135 can be designed to be at least partially embedded in the focusing carrier 123, and / or the focusing coil 136 can be designed to be at least partially embedded in the anti-vibration carrier 121, so as to reduce the lateral space occupied by the focusing drive assembly 1320, and further reduce the lateral dimension of the motor 10.

[0110] As mentioned above, in the present application, the focusing driving assembly 1320 and the anti-shake driving assembly 1310 are both of the moving magnet type, and accordingly, the focusing magnet 135 is mounted on the focusing carrier 123; the first anti-shake magnet 131 and the second anti-shake magnet 133 are mounted on the anti-shake carrier 121; the focusing coil 136 is mounted on the anti-shake carrier 121 or the base 111; the first anti-shake coil 132 and the second anti-shake coil 134 are mounted on the base 111; such arrangement facilitates subsequent wiring of the focusing coil 136, the first anti-shake coil 132 and the second anti-shake coil 134, and realizes electrical conduction of the focusing coil 136, the first anti-shake coil 132 and the second anti-shake coil 134. Specifically, on one hand, the mounting carrier of the focusing coil 136 (i.e., the anti-shake carrier 121 or the base 111) is similar to or the same as the mounting carrier of the first anti-shake coil 132 and the second anti-shake coil 134 (i.e., the base 111), so that the focusing coil 136, the first anti-shake coil 132 and the second anti-shake coil 134 are more convenient to wire. On the other hand, the anti-shake carrier 121 and the base 111 are closer to the outside of the motor 10 relative to the focusing carrier 123, facilitating outward extension of the conductive structure electrically connected to the focusing coil 136, the first anti-shake coil 132 and the second anti-shake coil 134.

[0111] In the present application, at least one side of the motor 10 is not provided with the driving assembly 13, and accordingly, at least one side of the camera module is not provided with the driving assembly 13, so that when the camera module is mounted on a terminal mobile device, if the terminal mobile device is provided with other camera modules, the side of the camera module of the present application which is not provided with the driving assembly 13 can be adjacent to the other camera modules, so as to avoid magnetic interference between the multiple camera modules.

[0112] It is worth mentioning that in the present application, the magnets and coils of the driving assembly 13 are arranged in the transverse direction, on one hand, compared with the arrangement of the magnets and coils in the optical axis direction D, the height dimension of the motor 10 can be reduced to some extent; on the other hand, since the two adjacent pairs of magnets-coils are arranged in different transverse directions, for example, the first anti-shake coil 132 and the first anti-shake magnet 131 are arranged in the first axis direction D1, and the second anti-shake coil 134 and the second anti-shake magnet 133 are arranged in the second axis direction D2, compared with the arrangement of all the magnets-coils in the up-down direction, the magnetic field of one pair of magnets-coils moving in one direction will not affect the magnetic field of the other pair of magnets-coils in another direction to some extent.

[0113] In addition, in the present application, as mentioned above, Figure 2As shown, the focus driving assembly 1320 and the anti-shake driving assembly 1310 are arranged at different sides of the motor 10, i.e., the fourth side, the second side and the first side, which on the one hand can avoid mutual interference between the focus driving assembly 1320 and the anti-shake driving assembly 1310 to some extent, and help to ensure the stability of the respective driving; on the other hand, the space for arranging each magnet is increased, and the overall magnetic field is uniformly distributed, which helps to improve the anti-shake and focusing effect.

[0114] It is also worth mentioning that, in an embodiment of the present application, the lower surface of the focus driving assembly 1320 of the motor 10 for driving the lens assembly 20 to focus automatically is at a relatively low height. Specifically, the bottom surface of the focus magnet 135 of the focus driving assembly 1320 is lower than the bottom surface of the first anti-shake magnet 131 and / or the bottom surface of the second anti-shake magnet 133 of the anti-shake driving assembly 1310; the bottom surface of the focus coil 136 of the focus driving assembly 1320 is lower than the bottom surface of the first anti-shake coil 132 and / or the bottom surface of the second anti-shake coil 134 of the anti-shake driving assembly 1310. In this way, not only is it beneficial to reduce the height dimension of the motor 10, and thus the height dimension of the camera module, but it also increases the focus movement stroke, and thus improves the focusing function of the camera module.

[0115] It can be understood that the larger the size of the focus magnet 135 and the focus coil 136 in the height direction of the motor 10, the greater the driving force and the longer the driving stroke that the focus driving assembly 1320 can provide. However, increasing the size of the focus magnet 135 and the focus coil 136 in the height direction of the motor 10 can result in an increase in the height dimension of the motor 10. In the present application, the size of the focus magnet 135 and the focus coil 136 in the height direction of the motor 10 is increased by extending the focus magnet 135 and the focus coil 136 downward, so as to increase the focus movement stroke and thus improve the focusing function of the camera module. Further, it is also possible to avoid increasing the height dimension of the motor 10. Moving the focus magnet 135 and the focus coil 136 downward as a whole can also reduce the height dimension of the motor 10.

[0116] In the embodiment of the present application, as shown in FIG. 1, the focus driving assembly 1320 and the anti-shake driving assembly 1310 are arranged at different sides of the motor 10, i.e., the fourth side, the second side and the first side, which on the one hand can avoid mutual interference between the focus driving assembly 1320 and the anti-shake driving assembly 1310 to some extent, and help to ensure the stability of the respective driving; on the other hand, the space for arranging each magnet is increased, and the overall magnetic field is uniformly distributed, which helps to improve the anti-shake and focusing effect. Figure 2As shown, the support assembly 14 includes three support portions, wherein the three support portions are a first support portion 141, a second support portion 142, and a third support portion 143. Specifically, the first support portion 141 and the second support portion 142 are configured to support and guide the anti-shake carrier 121; the third support portion 143 is configured to support and guide the focus carrier 123. The first support portion 141 is disposed on the upper side of the frame 122 between the frame 122 and the anti-shake carrier 121; the second support portion 142 is disposed on the lower side of the frame 122 between the anti-shake carrier 121 and the base 111.

[0117] As shown in Figure 2 , Figure 10 and Figure 11 , the first support portion 141 includes three balls 1410, and the three balls 1410 of the first support portion 141 are disposed between the frame 122 and the anti-shake carrier 121 to enable the anti-shake carrier 121 to move relative to the frame 122 with less friction; the second support portion 142 includes another three balls 1410, and the three balls 1410 of the second support portion 142 are disposed between the frame 122 and the base 111 to enable the frame 122 to move relative to the base 111 with less friction.

[0118] In one example of the present application, as shown in Figure 2 , Figure 5 and Figure 6 , the frame 122 is L-shaped and includes a first side 1221 and a second side 1222. The second side 1222 is folded relative to the first side 1221. Accordingly, the frame 122 has a corner 1223 between the first side 1221 and the second side 1222. The corner 1223 is between the first side and the second side of the motor 10; the first side 1221 extends between the first side and the third side of the motor 10 along the second axis direction D2, and the end of the first side 1221 is close to the third side of the motor 10; the second side 1222 extends between the second side and the fourth side of the motor 10 along the first axis direction D1, and the end of the second side 1222 is close to the fourth side of the motor 10. Accordingly, the length direction of the first side 1221 is consistent with the second axis direction D2; the length direction of the second side 1222 is consistent with the first axis direction D1.

[0119] The three balls 1410 of the first support part 141 are respectively arranged on the upper side of the end part of the first side 1221, the upper side of the corner 1223 and the upper side of the end part of the second side 1222 of the L-shaped frame 122. The three balls 1410 of the second support part 142 are respectively arranged on the lower side of the end part of the first side 1221, the lower side of the corner 1223 and the lower side of the end part of the second side 1222 of the L-shaped frame 122.

[0120] Specifically, the side of the frame 122 facing the anti-shake carrier 121 (i.e. the upper side of the frame 122) and the side of the frame 122 facing the base 111 (i.e. the lower side of the frame 122) are respectively provided with three ball grooves. The three ball grooves on the side of the frame 122 facing the anti-shake carrier 121 are frame top ball grooves 1224, which are respectively arranged on the upper side of the end part of the first side 1221, the upper side of the corner 1223 and the upper side of the end part of the second side 1222 of the frame 122. The three ball grooves on the side of the frame 122 facing the base 111 are frame bottom ball grooves 1225, which are respectively arranged on the lower side of the end part of the first side 1221, the lower side of the corner 1223 and the lower side of the end part of the second side 1222 of the frame 122.

[0121] The side of the base 111 facing the frame 122 (i.e. the upper side of the base 111) is also provided with three ball grooves at the corresponding positions (i.e. the positions opposite to the three frame bottom ball grooves 1225 in the optical axis direction D), which are base ball grooves 1115; the sizes of the three base ball grooves 1115 are respectively greater than the sizes of the three frame bottom ball grooves 1225 at the corresponding positions, as shown in Figure 10 More specifically, the size of the base ball groove 1115 in the length direction thereof is greater than the size of the corresponding frame bottom ball groove 1225.

[0122] In particular, in an embodiment of the present application, as Figure 7 and Figure 10As shown, the base ball groove 1115 extends along the first axial direction D1, i.e. the length direction of the base ball groove 1115 is the first axial direction D1, and the size of the base ball groove 1115 in the first axial direction D1 is greater than the size of the frame bottom ball groove 1225. Such an advantage is that the part of the frame 122 where the ball 1410 is arranged can be designed to be smaller, thereby reducing the size of the frame 122. Further, the size of the frame bottom ball groove 1225 also extends along the first axial direction D1, i.e. the size of the frame bottom ball groove 1225 and the base ball groove 1115 are both long strip-shaped ball grooves extending along the first axial direction D1, but the size of the frame bottom ball groove 1225 in the first axial direction D1 is shorter, which is conducive to keeping the ball 1410 rolling to reduce the risk of the ball 1410 becoming stuck and sliding.

[0123] Further, the two frame bottom ball grooves 1225 arranged on the frame 122 along the first axial direction D1 are guide grooves with lateral guiding function, the cross section is V-shaped or approximately V-shaped, the width gradually decreases from top to bottom in the depth direction, for limiting the rolling direction of the ball 1410; the other frame bottom ball groove 1225 is a support groove without lateral guiding function, the cross section is U-shaped, the width is consistent in the depth direction, and does not limit the rolling direction of the ball 1410; similarly, the two base ball grooves 1115 arranged on the base 111 along the first axial direction D1 are guide grooves with lateral guiding function, the cross section is V-shaped or approximately V-shaped, the width gradually decreases from top to bottom in the depth direction, for limiting the rolling direction of the ball 1410, and the other base ball groove 1115 is a support groove without lateral guiding function, the cross section is U-shaped, the width is consistent in the depth direction, and does not limit the rolling direction of the ball 1410.

[0124] Correspondingly, the side of the anti-shake carrier 121 facing the frame 122 is also provided with three ball grooves at the corresponding positions (i.e. the positions opposite to the three frame top ball grooves 1224 in the optical axis direction D), which are three carrier ball grooves 1211; the size of the three carrier ball grooves 1211 is greater than the size of the three frame top ball grooves 1224 respectively. More specifically, the size of the carrier ball groove 1211 in its length direction is greater than the size of the corresponding frame top ball groove 1224.

[0125] In particular, as Figure 8As shown, the carrier ball groove 1211 extends along the second axial direction D2, i.e. the length direction of the carrier ball groove 1211 is the second axial direction D2. The size of the carrier ball groove 1211 in the second axial direction D2 is greater than the size of the frame top surface ball groove 1224 in the second axial direction D2. Such an advantage is that the part of the frame 122 that sets the ball 1410 can be designed to be smaller in size, thereby reducing the size of the frame 122. Further, the frame top surface ball groove 1224 also extends along the second axial direction D2, i.e. the frame top surface ball groove 1224 and the carrier ball groove 1211 are both long strip-shaped ball grooves extending along the second axial direction D2, but the size of the frame top surface ball groove 1224 in the second axial direction D2 is shorter, which is conducive to keeping the ball 1410 rolling to reduce the risk of the ball 1410 being stuck and becoming sliding friction.

[0126] Further, the two frame top surface ball grooves 1224 provided on the frame 122 along the second axial direction D2 are guide grooves with lateral guiding function, the cross section is V-shaped or approximately V-shaped, the width gradually decreases from top to bottom in the depth direction, for limiting the rolling direction of the ball 1410, and the other frame top surface ball groove 1224 is a support groove without lateral guiding function, the cross section is U-shaped, the width is consistent in the depth direction, and does not limit the rolling direction of the ball 1410; Similarly, the two carrier ball grooves 1211 provided on the anti-shake carrier 121 along the second axial direction D2 are guide grooves with lateral guiding function, the cross section is V-shaped or approximately V-shaped, the width gradually decreases from top to bottom in the depth direction, for limiting the rolling direction of the ball 1410, and the other carrier ball groove 1211 is a support groove without lateral guiding function, the cross section is U-shaped, the width is consistent in the depth direction, and does not limit the rolling direction of the ball 1410.

[0127] Further, the length extension direction of the carrier ball groove 1211 on the anti-shake carrier 121 is perpendicular to the length extension direction of the base ball groove 1115 on the base 111. Further, if the frame top surface ball groove 1224 and the frame bottom surface ball groove 1225 on the frame 122 have length directions, they are also arranged perpendicularly.

[0128] It should be appreciated that in other embodiments of the present application, the base ball groove 1115 can be designed to extend along the second axis direction D2, i.e. the length direction of the base ball groove 1115 is the second axis direction D2, and the size of the base ball groove 1115 in the second axis direction D2 is greater than the frame bottom ball groove 1225. Such an advantage is that the size of the frame 122 can be reduced by designing the size of the part of the frame 122 where the ball 1410 is arranged to be smaller. Further, the frame bottom ball groove 1225 also extends along the second axis direction D2, i.e. the frame bottom ball groove 1225 and the base ball groove 1115 are both long strip-shaped ball grooves extending along the second axis direction D2, but the size of the frame bottom ball groove 1225 in the second axis direction D2 is shorter, which is beneficial to keep the ball 1410 rolling to reduce the risk of the ball 1410 being stuck to become sliding friction.

[0129] Further, in other embodiments of the present application, the two frame bottom ball grooves 1225 arranged on the frame 122 along the second axis direction D2 can be designed as guide grooves with lateral guiding function, which are V-shaped in cross section and gradually decrease in width from top to bottom in the depth direction to limit the rolling direction of the ball 1410, and the other frame bottom ball groove 1225 is a support groove without lateral guiding function, which is U-shaped in cross section and has consistent width in the depth direction without limiting the rolling direction of the ball 1410. Similarly, the two base ball grooves 1115 arranged on the base 111 along the second axis direction D2 are guide grooves with lateral guiding function, which are V-shaped in cross section and gradually decrease in width from top to bottom in the depth direction to limit the rolling direction of the ball 1410, and the other base ball groove 1115 is a support groove without lateral guiding function, which is U-shaped in cross section and has consistent width in the depth direction without limiting the rolling direction of the ball 1410.

[0130] In other embodiments of the present application, the carrier ball groove 1211 can be designed to extend along the first axis direction D1, i.e. the length direction of the carrier ball groove 1211 is the first axis direction D1, and the size of the carrier ball groove 1211 in the first axis direction D1 is greater than the frame top ball groove 1224. Such an advantage is that the size of the frame 122 can be reduced by designing the size of the part of the frame 122 where the ball 1410 is arranged to be smaller. Further, the frame top ball groove 1224 also extends along the first axis direction D1, i.e. the frame top ball groove 1224 and the carrier ball groove 1211 are both long strip-shaped ball grooves extending along the first axis direction D1, but the size of the frame top ball groove 1224 in the first axis direction D1 is shorter, which is beneficial to keep the ball 1410 rolling to reduce the risk of the ball 1410 being stuck to become sliding friction.

[0131] Furthermore, in other embodiments of this application, the two frame top surface ball grooves 1224 provided on the frame 122 along the first axis direction D1 can be designed as guide grooves with lateral guiding function, having a V-shaped cross-section and a width that gradually decreases from top to bottom in the depth direction, used to restrict the rolling direction of the ball 1410. The other frame top surface ball groove 1224 is a support groove without lateral guiding function, having a U-shaped cross-section and a consistent width in the depth direction, and does not restrict the rolling direction of the ball 1410. Similarly, the two carrier ball grooves 1211 provided on the anti-shake carrier 121 along the first axis direction D1 are guide grooves with lateral guiding function, having a V-shaped cross-section and a width that gradually decreases from top to bottom in the depth direction, used to restrict the rolling direction of the ball 1410. The other carrier ball groove 1211 is a support groove without lateral guiding function, having a U-shaped cross-section and a consistent width in the depth direction, and does not restrict the rolling direction of the ball 1410.

[0132] It is worth mentioning that a metal sheet can be provided at the bottom of at least one ball groove. For example, a metal sheet can be provided at the bottom of the ball groove on the upper side of the frame 122, the bottom of the ball groove on the lower side of the frame 122, the bottom of the ball groove 1115 of the base, and the bottom of the ball groove 1211 of the carrier.

[0133] It is worth mentioning that the metal sheet at the bottom of the ball grooves on the upper side of the plurality of frames 122 can be the same metal sheet; similarly, the metal sheet at the bottom of the ball grooves on the lower side of the plurality of frames 122 can be the same metal sheet; the metal sheet at the bottom of the ball grooves 1115 of the plurality of bases can be the same metal sheet; and the metal sheet at the bottom of the ball grooves 1211 of the plurality of carriers can be the same metal sheet.

[0134] In one embodiment of this application, the frame 122 is adopted The process involves injection molding plastic into the metal part 1210 or embedding the metal part 1210 into the plastic. Accordingly, such as Figure 16 As shown, the frame 122 includes a metal part 1210 and a plastic part 1220. The metal part 1210 may be implemented as a metal sheet.

[0135] In an example of the present application, the metal piece 1210 is L-shaped, including a first metal edge 1201 and a second metal edge 1202. The second metal edge 1202 is turned relative to the first metal edge 1201. Accordingly, the metal piece 1210 has a metal turning angle 1203 between the first metal edge 1201 and the second metal edge 1202. The plastic piece 1220 includes at least a first plastic seat 1204, a second plastic seat 1205, and a third plastic seat 1206. The first plastic seat 1204 is injection molded at the end of the first metal edge 1201, forming the first edge 1221 with the first metal edge 1201. The second plastic seat 1205 is injection molded at the end of the second metal edge 1202, forming the second edge 1222 with the second metal edge 1202. The third plastic seat 1206 is injection molded at the metal turning angle 1203, forming the turning angle 1223 with the metal turning angle 1203.

[0136] In another example of the present application, the metal piece 1210 is L-shaped, including a first metal edge 1201 and a second metal edge 1202. The second metal edge 1202 is turned relative to the first metal edge 1201. Accordingly, the metal piece 1210 has a metal turning angle 1203 between the first metal edge 1201 and the second metal edge 1202. The plastic piece 1220 is L-shaped, including a first plastic edge and a second plastic edge. The second plastic edge is turned relative to the first plastic edge. Accordingly, the plastic piece 1220 has a plastic turning angle between the first plastic edge and the second plastic edge. The first plastic edge is injection molded at the first metal edge 1201, forming the first edge 1221 with the first metal edge 1201, wherein the part of the first plastic edge that is injection molded at the end of the first metal edge 1201 forms a first plastic seat 1204; the second plastic edge is injection molded at the second metal edge 1202, forming the second edge 1222 with the second metal edge 1202, wherein the part of the second plastic edge that is injection molded at the end of the second metal edge 1202 forms a second plastic seat 1205; and the plastic turning angle is injection molded at the metal turning angle 1203, forming a third plastic seat 1206, and forming the turning angle 1223 with the metal turning angle 1203.

[0137] In yet another example of the present application, the plastic piece 1220 is L-shaped, including a first plastic edge and a second plastic edge. The second plastic edge is folded relative to the first plastic edge. Accordingly, the plastic piece 1220 has a plastic folding angle between the first plastic edge and the second plastic edge. The end of the first plastic edge forms a first plastic seat 1204, the end of the second plastic edge forms a second plastic seat 1205, and the plastic folding angle forms a third plastic seat 1206. The metal piece 1210 includes at least a first metal portion, a second metal portion, and a third metal portion. The first metal portion is embedded in the first plastic seat 1204, forming the first edge 1221 with the first plastic edge. The second metal portion is embedded in the second plastic seat 1205, forming the second edge 1222 with the second plastic edge. The third metal portion is embedded in the third plastic seat 1206, forming the folding angle 1223 with the third plastic seat 1206.

[0138] The first plastic seat 1204, the second plastic seat 1205, and the third plastic seat 1206 are used to support the three balls 1410 of the first support portion 141 and the three balls 1410 of the second support portion 142. Specifically, a portion of the first plastic seat 1204, a portion of the second plastic seat 1205, and a portion of the third plastic seat 1206 are located on the upper side of the metal piece 1210, used to support the three balls 1410 of the first support portion 141; another portion of the first plastic seat 1204, another portion of the second plastic seat 1205, and another portion of the third plastic seat 1206 are located on the lower side of the metal piece 1210, used to support the three balls 1410 of the second support portion 142.

[0139] The metal piece 1210 can be exposed to the bottom of at least one ball groove, for example, the bottom of the ball groove on the upper side of the frame 122, the bottom of the ball groove on the lower side of the frame 122, the bottom of the base ball groove 1115, and the bottom of the carrier ball groove 1211. The metal piece 1210 can also not be exposed to the bottom of any ball groove, and further, the metal piece 1210 can be completely covered by the plastic piece 1220.

[0140] It is also worth mentioning that in the embodiment where the movable assembly 12 does not provide the frame 122, the balls 1410 and the "cross" ball grooves can be provided between the anti-shake carrier 121 and the base 111, achieving support and guidance in two directions by a single layer of balls 1410.

[0141] In an embodiment of the present application, the third support portion 143 is disposed on the side where the focus driving assembly 1320 is located. In this way, the point of action of the force generated by the focus driving assembly 1320 is closer to the third support portion 143, thereby reducing the overturning moment generated during focusing. The focus carrier 123 generates a smaller tilting or offset moment, so that the focus carrier 123 is less likely to tilt during focusing, thereby ensuring the sharpness of the image and the accuracy of focusing. Moreover, since the tilting of the focus carrier 123 is reduced, the focus driving assembly 1320 can respond to the focusing instruction more quickly, thereby achieving fast and accurate focusing. Accordingly, in an embodiment of the present application, the focus driving assembly 1320 and the third support portion 143 are disposed on the fourth side of the focus carrier 123.

[0142] In an embodiment of the present application, as shown in Figures 2 to 4 the third support portion 143 includes two guide rods, wherein the two guide rods are a first guide rod 1420 and a second guide rod 1430, respectively. The first guide rod 1420 and the second guide rod 1430 are fixed between the anti-shake carrier 121 and the focus carrier 123 and are disposed on both sides of the focus magnet 135, respectively. The length extension direction of the first guide rod 1420 and the second guide rod 1430 is consistent with the optical axis direction D. The length of the first guide rod 1420 and the second guide rod 1430 is greater than the height of the focus carrier 123, or even greater than the movement stroke of the focus carrier 123 along the optical axis direction D, so that the focus carrier 123 can be supported within the movement stroke.

[0143] In an example of the present application, the first guide rod 1420 and the second guide rod 1430 are fixed to the anti-shake carrier 121. Specifically, as shown in Figure 10 the anti-shake carrier 121 includes a carrier insert 1212 embedded in the interior thereof, and at least part of the carrier insert 1212 extends horizontally from the bottom side of the anti-shake carrier 121 out of the anti-shake carrier 121. The first guide rod 1420 and the second guide rod 1430 are fixed to the carrier insert 1212 of the anti-shake carrier 121.

[0144] More specifically, the carrier insert 1212 is at least partially a vertical portion embedded in the side wall of the anti-shake carrier 121. The carrier insert 1212 is a metal insert for enhancing the structural strength of the side wall of the anti-shake carrier 121. The vertical portion of the carrier insert 1212 is in the shape of a "mouth" character, as shown in Figure 9The "mouth" shape structure of the vertical part of the carrier insert 1212 is hollowed in the middle, which can be used to accommodate the focusing coil 136, focusing sensing element 163 and other elements. It should be understood that the side wall of the anti-shake carrier 121 for mounting the focusing coil 136 can be provided with a through hole, so that the focusing coil 136 is accommodated in the through hole of the side wall of the anti-shake carrier 121.

[0145] It should be understood that the first guide rod 1420 and the second guide rod 1430 can also be fixed between the anti-shake carrier 121 and the focusing carrier 123 in other ways, for example, by being fixed to the anti-shake carrier 121 in other ways, or being fixed to other parts of the anti-shake carrier 121, or being fixed to the focusing carrier 123.

[0146] In an example of the present application, the first guide rod 1420 and the second guide rod 1430 are integrally formed with the anti-shake carrier 121. For example, the first guide rod 1420 and the second guide rod 1430 are embedded in the anti-shake carrier 121 during the injection molding of the anti-shake carrier 121. In this way, the first guide rod 1420 and the second guide rod 1430 can be directly fixed to the anti-shake carrier 121, which not only helps to ensure the linearity of the first guide rod 1420 and the second guide rod 1430, but also reduces the height of the first guide rod 1420 and the second guide rod 1430, thereby reducing the height of the motor 10. Further, the carrier insert 1212 can be eliminated to further reduce the height of the motor 10.

[0147] Specifically, the positions of the first guide rod 1420 and the second guide rod 1430 in the anti-shake carrier 121 can be determined first, and then the first guide rod 1420 and the second guide rod 1430 can be integrally injection molded with the anti-shake carrier 121 by using an insert injection molding process. Of course, a connecting structure can be provided between the first guide rod 1420 and the second guide rod 1430, and then the first guide rod 1420 and the second guide rod 1430 can be integrally injection molded with the anti-shake carrier 121 by using an insert injection molding process. In this way, the parallelism between the first guide rod 1420 and the second guide rod 1430 can be improved.

[0148] Two guide rod grooves are arranged between the focusing carrier 123 and the anti-shake carrier 121. The two guide rod grooves are respectively a first guide rod groove 1231 and a second guide rod groove 1232. The first guide rod groove 1231 and the second guide rod groove 1232 extend along the optical axis direction D. The third support portion 143 can be tightly fitted with the first guide rod groove 1231 and the second guide rod groove 1232, that is, closely fitted, or loosely fitted with the first guide rod groove 1231 and the second guide rod groove 1232, that is, fitted with a certain movability.

[0149] In particular, as shown in the first embodiment of the present application, Figure 10 The first guide rod groove 1231 is arranged on the side of the motor 10 without the L-shaped frame. Correspondingly, the first guide rod groove 1231 is arranged at a position without the arrangement of the ball 1410 of the motor 10, for example, the corner between the third side and the fourth side of the motor 10, and is a guide groove with a transverse guiding function, the width of which gradually decreases from inside to outside in the depth direction; the width of the second guide rod groove 1232 is basically consistent from inside to outside in the depth direction, and it does not have a transverse guiding function.

[0150] It is worth mentioning that the arrangement of the L-shaped frame 122 and the ball 1410 provides a setting space for the V-shaped first guide rod groove 1231. Specifically, compared with a quadrilateral frame, the L-shaped frame 122 has an open missing corner, which can exactly provide a setting space for the V-shaped first guide rod groove 1231 which needs a larger setting space. Correspondingly, in order not to increase the transverse dimension of the motor 10, the second guide rod groove 1232 opposite to the first guide rod groove 1231 in the second axis direction D2 can be a guide rod groove without a transverse guiding function. Correspondingly, the arrangement mode of the two guide rod grooves is that one of the two guide rod grooves is a V-shaped guide rod groove with a guiding function, and the other is a guide rod groove without a transverse guiding function. Further, in order to reduce the space occupied by the guide rod groove, the second guide rod groove 1232 close to the ball 1410 is arranged as a semi-open groove with a flat groove bottom surface, so that its size is smaller.

[0151] It is worth mentioning that the contact position, number and area of the first guide rod 1420 and the second guide rod 1430 with the guide rod groove will affect the wear degree of the focusing carrier 123. The present application reduces the wear of the focusing carrier 123 caused by long-term movement through the design of the contact position and number of the first guide rod 1420 and the second guide rod 1430 with the guide rod groove, improves the durability and reliability of the focusing carrier 123, and further improves the durability and reliability of the motor 10.

[0152] In an embodiment of the present application, as shown in the first embodiment of the present application, Figure 2As shown, the focusing carrier 123 has at least three contact positions formed on the sidewall thereof, which are a first contact position 102, a second contact position 103 and a third contact position 104. In the opposite arrangement direction of the first guide rod 1420 and the second guide rod 1430, the first contact position 102 and the second contact position 103 are located on the same side of the focusing drive assembly 1320, and the third contact position 104 is located on the opposite side of the focusing drive assembly 1320 relative to the first contact position 102 and the second contact position 103. The first contact position 102 is located above the second contact position 103. The first contact position 102 is close to the top surface of the focusing carrier 123. The second contact position 103 is close to the bottom surface of the focusing carrier 123. The second contact position 103 is closer to the bottom surface of the focusing carrier 123 relative to the third contact position 104. The first contact position 102, the second contact position 103 and the third contact position 104 form a triangular support surface with the third support portion 143.

[0153] In an embodiment of the present application, the first guide rod 1420 is in contact with the first contact position 102 and the second contact position 103, and the second guide rod 1430 is in contact with the third contact position 104.

[0154] Correspondingly, in an embodiment of the present application, the number of contact positions between the focusing carrier 123 and the first guide rod 1420 is at least two, which are the first contact position 102 and the second contact position 103. The number of contact positions between the focusing carrier 123 and the second guide rod 1430 is at least one, which is the third contact position 104.

[0155] Specifically, the focusing carrier 123 is provided with a contact protrusion 1233 at each of the two opposite ends in the height direction of the first guide rod slot 1231; the first guide rod 1420 is in contact with the contact protrusions 1233 at the two opposite ends in the height direction of the first guide rod slot 1231; and the contact protrusions 1233 at the two opposite ends in the height direction of the first guide rod slot 1231 form the first contact position 102 and the second contact position 103. The focusing carrier 123 is provided with a contact protrusion 1233 at the middle portion in the height direction of the second guide rod slot 1232; the second guide rod 1430 is in contact with the contact protrusion 1233 at the middle portion in the height direction of the second guide rod slot 1232; and the contact protrusion 1233 at the middle portion in the height direction of the second guide rod slot 1232 forms the third contact position 104.

[0156] Correspondingly, in the optical axis direction D, the third contact position 104 is at a higher level than the second contact position 103 and at a lower level than the first contact position 102; the first contact position 102, the second contact position 103 and the third contact position 104 form a triangular position relationship. The first contact position 102, the second contact position 103 and the third contact position 104 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 123 adsorbed on the anti-shake carrier 121, and reduces the risk of the focusing carrier 123 overturning.

[0157] Since the second guide rod 1430 only needs to be in contact with one contact position, the length of the second guide rod 1430 can be shorter than the length of the first guide rod 1420. In this way, it helps to maintain the parallelism of the second guide rod 1430 and provides more space for the arrangement of other components.

[0158] It is worth mentioning that the third support part 143 can also be implemented in other ways and achieve triangular support in other ways. The third support part 143 can be implemented as a combination of a guide rod and a slider, or a combination of a guide rod and a ball 1410, or a combination of a slider and a ball 1410. The component in the third support part 143 that is in contact with the first contact position 102 can be a guide rod or a slider or a ball 1410, the component in contact with the second contact position 103 can be a guide rod or a slider or a ball 1410, and the component in contact with the third contact position 104 can be a guide rod or a slider or a ball 1410.

[0159] As shown in Figure 2 The magnetic attraction assembly 15 includes an anti-shake magnetic attraction piece 151 and a focusing magnetic attraction piece 152. The anti-shake magnetic attraction piece 151 is used for adsorbing the anti-shake carrier 121; the focusing magnetic attraction piece 152 is used for adsorbing the focusing carrier 123. Specifically, the anti-shake magnetic attraction piece 151 is used to adsorb the anti-shake carrier 121 to the frame 122 and the base 111; the focusing magnetic attraction piece 152 is used to adsorb the focusing carrier 123 to the anti-shake frame 122.

[0160] The focusing magnetic attraction piece 152 is located on the side of the focusing coil 136 away from the focusing magnet 135. The focusing magnetic attraction piece 152 has magnetic permeability and can be attracted to the focusing magnet 135. The magnetic attraction between the focusing magnetic attraction piece 152 and the focusing magnet 135 causes the focusing carrier 123 to be close to the anti-shake carrier 121, and the focusing carrier 123 is more tightly supported by the third support part 143, which can improve the driving stability and prevent the focusing carrier 123 and the anti-shake carrier 121 from falling. In other words, the magnetic attraction between the focusing magnetic attraction piece 152 and the focusing magnet 135 causes the focusing carrier 123 to be attracted to the side wall of the anti-shake carrier 121.

[0161] It is worth mentioning that in the present application, the resultant force of the magnetic attraction between the focusing carrier 123 and the anti-shake carrier 121 is expected to be biased to the side where the first contact position 102 and the second contact position 103 are located, more specifically, the resultant force of the magnetic attraction between the focusing carrier 123 and the anti-shake carrier 121 is expected to be biased to the side where the first contact position 102 and the second contact position 103 are located in the length direction of the focusing magnet 135 compared to the side where the third contact position 104 is located, so that the focusing carrier 123 is not prone to overturning relative to the anti-shake carrier 121, that is, it is not prone to deflection relative to the anti-shake carrier 121 with the first contact position 102 and the second contact position 103 as the pivot. To this end, the focusing magnetic attraction piece 152 affecting the magnetic field in which the focusing carrier 123 is located is specifically designed in the present application, for example, the overlapping area of the focusing magnetic attraction piece 152 with the focusing magnet 135 in the relative arrangement direction of the focusing magnet 135 and the focusing coil 136 is biased to the first contact position 102 and the second contact position 103, the first guide rod 1420 and the first guide rod groove 1231, so that the magnetic attraction between the focusing magnetic attraction piece 152 and the focusing magnet 135 is biased to the side where the first contact position 102 and the second contact position 103 are located, and then the resultant force of the magnetic attraction between the focusing carrier 123 and the anti-shake carrier 121 is biased to the side where the first contact position 102 and the second contact position 103 are located, while being biased to the first guide rod 1420 and the V-shaped first guide rod groove 1231 with a lateral guiding function, thereby improving the stability of the focusing carrier 123 supported on the side wall of the anti-shake carrier 121, so that the focusing carrier 123 is not prone to overturning relative to the anti-shake carrier 121, that is, it is not prone to deflection relative to the anti-shake carrier 121 with the first contact position 102 and the third contact position 104 as the pivot, or with the second contact position 103 and the third contact position 104 as the pivot, that is, the risk of overturning of the focusing carrier 123 is reduced.

[0162] In an embodiment of the present application, the position relationship between the focusing magnetic attracting piece 152 and the focusing magnet 135 is further represented as: the focusing magnetic attracting piece 152 is arranged eccentrically relative to the focusing magnet 135, i.e. the center of the focusing magnetic attracting piece 152 is not consistent with the center of the focusing magnet 135. Specifically, the center of the focusing magnetic attracting piece 152 is offset relative to the center of the focusing magnet 135 in the direction of the relative arrangement of the first guide rod 1420 and the second guide rod 1430 towards the first contact position 102 and the second contact position 103. Further represented as: the distance between the center of the focusing magnetic attracting piece 152 and the first contact position 102 in the direction of the relative arrangement of the first guide rod 1420 and the second guide rod 1430 is less than the distance between the center of the focusing magnetic attracting piece 152 and the third contact position 104 in the direction of the relative arrangement of the first guide rod 1420 and the second guide rod 1430; the distance between the focusing magnetic attracting piece 152 and the second contact position 103 in the direction of the relative arrangement of the first guide rod 1420 and the second guide rod 1430 is less than the distance between the focusing magnetic attracting piece 152 and the third contact position 104 in the direction of the relative arrangement of the first guide rod 1420 and the second guide rod 1430; or further represented as: the distance between the center of the focusing magnetic attracting piece 152 and the first contact position 102 in the direction of the relative arrangement of the first guide rod 1420 and the second guide rod 1430 is less than the distance between the center of the focusing magnet 135 and the first contact position 102 in the direction of the relative arrangement of the first guide rod 1420 and the second guide rod 1430; the distance between the center of the focusing magnetic attracting piece 152 and the second contact position 103 in the direction of the relative arrangement of the first guide rod 1420 and the second guide rod 1430 is less than the distance between the center of the focusing magnet 135 and the second contact position 103 in the direction of the relative arrangement of the first guide rod 1420 and the second guide rod 1430; the distance between the center of the focusing magnetic attracting piece 152 and the third contact position 104 in the direction of the relative arrangement of the first guide rod 1420 and the second guide rod 1430 is greater than the distance between the center of the focusing magnet 135 and the third contact position 104 in the direction of the relative arrangement of the first guide rod 1420 and the second guide rod 1430.

[0163] The height dimension of at least a portion of the focusing magnetic accumulator 152 is greater than the height dimension of the focusing magnet 135, that is, in the optical axis direction D, the dimension of at least a portion of the focusing magnetic accumulator 152 is greater than the dimension of the focusing magnet 135. Further, in one embodiment of this application, the height dimension of at least a portion of the focusing magnetic accumulator 152 is greater than or equal to the height of the focusing magnet 135 and the travel distance of the focusing magnet 135 in the optical axis direction D.

[0164] like Figure 2 and Figure 7 As shown, the image stabilization magnetic clasp 151 includes a first magnetic clasp 1511 and a second magnetic clasp 1512. The first magnetic clasp 1511 and the second magnetic clasp 1512 are fixed to the base 111 and are respectively opposite to the first image stabilization magnet 131 and the second image stabilization magnet 133. Specifically, the first magnetic clasp 1511 is located below the first image stabilization magnet 131 in the optical axis direction D and is opposite to the first image stabilization magnet 131 in the optical axis direction D. Thus, by means of the magnetic attraction between the first image stabilization magnet 131 and the first magnetic clasp 1511 along the optical axis direction D, the image stabilization carrier 121 is attracted to the base 111, and the frame 122 is clamped between the image stabilization carrier 121 and the base 111. The second magnetic attractor 1512 is located below the second anti-shake magnet 133 in the optical axis direction D and is opposite to the second anti-shake magnet 133 in the optical axis direction D. Thus, by means of the magnetic attraction between the second anti-shake magnet 133 and the second magnetic attractor 1512 along the optical axis direction D, the anti-shake carrier 121 is attracted to the base 111, and the frame 122 is clamped between the anti-shake carrier 121 and the base 111.

[0165] It is worth mentioning that the first anti-shake magnet 131 moves in the relative arrangement direction relative to the first anti-shake coil 132, and assuming that the first anti-shake magnet 131 exceeds the first magnetic attraction member 1511 in the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132 after movement, at this time, the first anti-shake magnet 131 and the first magnetic attraction member 1511 will generate a magnetic attraction force (component) in the movement direction, which will make the first anti-shake magnet 131 close to the first magnetic attraction member 1511 in the movement direction, thereby becoming the resistance of the anti-shake carrier 121 relative to the base 111 movement, therefore, in order to reduce the influence of the resistance generated between the first anti-shake magnet 131 and the first magnetic attraction member 1511 in the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132 after movement, the size of the first magnetic attraction member 1511 in the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132 is greater than the size of the first anti-shake magnet 131 in the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132.

[0166] Preferably, the size of the first magnetic attraction member 1511 in the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132 is greater than or equal to the sum of the size of the first anti-shake magnet 131 in the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132 and the movement stroke of the first anti-shake magnet 131 in the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132, so that the first anti-shake magnet 131 does not exceed the first magnetic attraction member 1511 in the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132 during the driving process of the first anti-shake magnet 131, which is manifested as: the orthographic projection of the first anti-shake magnet 131 in the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132 does not exceed the first magnetic attraction member 1511.

[0167] In an embodiment of the present application, the first anti-shake magnet 131 moves along the first axis direction D1, that is, the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132 is the first axis direction D1. Accordingly, the size of the first magnetic attraction member 1511 in the first axis direction D1 is greater than the size of the first anti-shake magnet 131 in the first axis direction D1, as Figure 7As shown. Preferably, the dimension of the first magnetic member 1511 in the first axial direction D1 is greater than or equal to the sum of the dimension of the first anti-shake magnet 131 in the first axial direction D1 and the travel distance of the first anti-shake magnet 131 in the first axial direction D1. Thus, during the movement of the first anti-shake magnet 131 relative to the first anti-shake coil 132 in the first axial direction D1, the first anti-shake magnet 131 never exceeds the first magnetic member 1511 in the first axial direction D1. This is manifested in that the orthographic projection of the first anti-shake magnet 131 in the optical axis direction D does not exceed the first magnetic member 1511 in the first axial direction D1.

[0168] Similarly, if the second stabilizing magnet 133 moves relative to the second stabilizing coil 134 in a relative setting direction, and assuming that after its movement, the second stabilizing magnet 133 extends all or part of its movement direction relative to the second stabilizing coil 134 beyond the second magnetic attractor 1512, then the second stabilizing magnet 133 and the second magnetic attractor 1512 will generate a magnetic attraction force (component force) along this movement direction. This magnetic attraction force will cause the second stabilizing magnet 133 to move closer to the second magnetic attractor 1512 along this movement direction, thus becoming a resistance to the movement of the second stabilizing carrier 121 relative to the base 111. Therefore, in this application, in order to reduce the influence of the resistance generated between the second stabilizing magnet 133 and the second magnetic attractor 1512 along the movement direction of the second stabilizing magnet 133 relative to the second stabilizing coil 134 after its movement, the size of the second magnetic attractor 1512 in the movement direction of the second stabilizing magnet 133 relative to the second stabilizing coil 134 is designed to be larger than the size of the second stabilizing magnet 133 in the movement direction of the second stabilizing coil 134.

[0169] Preferably, the dimension of the second magnetic chuck 1512 in the direction of movement of the second anti-shake magnet 133 relative to the second anti-shake coil 134 is greater than or equal to the sum of the dimension of the second anti-shake magnet 133 in the direction of movement of the second anti-shake coil 134 and the travel distance of the second anti-shake magnet 133 in the direction of movement of the second anti-shake coil 134. This ensures that the second anti-shake magnet 133 never exceeds the second magnetic chuck 1512 in the direction of movement of the second anti-shake coil 134 during its driving process. Specifically, the orthographic projection of the second anti-shake magnet 133 on the optical axis direction D does not exceed the second magnetic chuck 1512 in the direction of movement of the second anti-shake coil 134.

[0170] In an embodiment of the present application, the second anti-shake magnet 133 moves along the second axial direction D2, i.e., the moving direction of the second anti-shake magnet 133 relative to the second anti-shake coil 134 is the second axial direction D2. Accordingly, the size of the second magnetic attraction member 1512 in the second axial direction D2 is greater than the size of the second anti-shake magnet 133 in the second axial direction D2, as shown in Figure 7 Preferably, the size of the second magnetic attraction member 1512 in the second axial direction D2 is greater than or equal to the sum of the size of the second anti-shake magnet 133 in the second axial direction D2 and the moving stroke of the second anti-shake magnet 133 in the second axial direction D2, so that the second anti-shake magnet 133 does not exceed the second magnetic attraction member 1512 in the second axial direction D2 during the movement of the second anti-shake magnet 133 relative to the second anti-shake coil 134 in the second axial direction D2, which is manifested as that the orthographic projection of the second anti-shake magnet 133 in the optical axis direction D on the second axial direction D2 does not exceed the second magnetic attraction member 1512.

[0171] It is worth mentioning that if the first magnetic attraction member 1511 is uniform in structure, when the first anti-shake magnet 131 is driven to move far away from the first anti-shake coil 132 (inward), the driving force between the first anti-shake magnet 131 and the first anti-shake coil 132 is greatly reduced, while the magnetic restoring force of the part of the first magnetic attraction member 1511 outside the first anti-shake magnet 131 relative to the magnetic attraction force of the first anti-shake magnet 131 is still great, making it difficult for the first anti-shake magnet 131 to resist the magnetic restoring force of the first magnetic attraction member 1511 relative to the magnetic attraction force of the first anti-shake magnet 131, resulting in limited stroke of the first anti-shake magnet 131 and the anti-shake carrier 121.

[0172] Based on this, the present application proposes to provide an opening in the outer part (the part close to the first anti-shake magnet 131) of the first magnetic attraction member 1511 to reduce the magnetic restoring force of the first magnetic attraction member 1511 relative to the first anti-shake magnet 131 during the process of driving the first anti-shake magnet 131 to move away from the first anti-shake coil 132 (inward).

[0173] Correspondingly, in an embodiment of the present application, as shown in Figure 17As shown, the first magnetic attraction member 1511 has a first opening 1501. The center of the first opening 1501 is offset from the center of the first magnetic attraction member 1511 towards the first OIS magnet 131 relative to the movement direction of the first OIS magnet 131 relative to the first OIS coil 132. In this way, when the first OIS magnet 131 is in the initial position, i.e. not driven to move, the center of the first OIS magnet 131 is substantially aligned with the center of the first opening 1501, the magnetic attraction force between the portion of the first magnetic attraction member 1511 corresponding to the first OIS magnet 131 in the optical axis direction D and the first OIS magnet 131 is substantially equal to the magnetic attraction force between the other portions of the first magnetic attraction member 1511 and the first OIS magnet 131, both of which can substantially cancel each other out. When the first OIS magnet 131 moves away from or towards the first OIS coil 132, the magnetic attraction force between the first magnetic attraction member 1511 and the first OIS magnet 131 will form a magnetic restoring force on the first OIS magnet 131, which helps to reset the OIS carrier 121. The direction of the magnetic restoring force is opposite to the direction of the driving force formed by the magnetic attraction force between the first OIS magnet 131 and the first OIS coil 132.

[0174] When the first OIS magnet 131 is too far away from the first OIS coil 132, the driving force formed by the first OIS magnet 131 and the first OIS coil 132 decreases. Since the first magnetic attraction member 1511 has the first opening 1501 on the side away from the movement direction of the first OIS magnet 131, the magnetic attraction restoring force between the first magnetic attraction member 1511 and the first OIS magnet 131 on the first OIS magnet 131 can reduce the resistance of the driving force formed by the magnetic attraction force between the first OIS magnet 131 and the first OIS coil 132.

[0175] Similarly, if the second magnetic attraction member 1512 has uniform structure everywhere, when the second OIS magnet 133 is driven to move far away from the second OIS coil 134 (inward), the driving force between the second OIS magnet 133 and the second OIS coil 134 decreases to a large extent, while the magnetic attraction restoring force on the second OIS magnet 133 formed by the portion of the second magnetic attraction member 1512 outside the second OIS magnet 133 and the second OIS magnet 133 is still large, making it difficult for the second OIS magnet 133 to resist the magnetic attraction restoring force formed by the second magnetic attraction member 1512 and the second OIS magnet 133, resulting in limited travel of the second OIS magnet 133 and the OIS carrier 121.

[0176] Therefore, the second magnetic attraction member 1512 is provided with a second opening 1502. The center of the second opening 1502 is offset from the center of the second magnetic attraction member 1512 towards the second anti-shake magnet 133 in the direction of movement of the second anti-shake magnet 133 relative to the second anti-shake coil 134. In this way, when the second anti-shake magnet 133 is in the initial position, i.e. not driven to move, the center of the second anti-shake magnet 133 is substantially aligned with the center of the second opening 1502, and the magnetic attraction force between the part of the second magnetic attraction member 1512 corresponding to the second anti-shake magnet 133 in the optical axis direction D and the second anti-shake magnet 133 is substantially equal to the magnetic attraction force between the other part of the second magnetic attraction member 1512 and the second anti-shake magnet 133, and the two can substantially cancel each other out. When the second anti-shake magnet 133 moves away from or approaches the second anti-shake coil 134, the magnetic attraction force between the second magnetic attraction member 1512 and the second anti-shake magnet 133 will form a magnetic return force on the second anti-shake magnet 133, which helps to reset the anti-shake carrier 121. The direction of the magnetic return force is opposite to the direction of the driving force formed by the magnetic attraction force between the second anti-shake magnet 133 and the second anti-shake coil 134.

[0177] Correspondingly, in an embodiment of the present application, as shown in Figure 17 the second magnetic attraction member 1512 is provided with a second opening 1502. The center of the second opening 1502 is offset from the center of the second magnetic attraction member 1512 towards the second anti-shake magnet 133 in the direction of movement of the second anti-shake magnet 133 relative to the second anti-shake coil 134. In this way, when the second anti-shake magnet 133 is in the initial position, i.e. not driven to move, the center of the second anti-shake magnet 133 is substantially aligned with the center of the second opening 1502, and the magnetic attraction force between the part of the second magnetic attraction member 1512 corresponding to the second anti-shake magnet 133 in the optical axis direction D and the second anti-shake magnet 133 is substantially equal to the magnetic attraction force between the other part of the second magnetic attraction member 1512 and the second anti-shake magnet 133, and the two can substantially cancel each other out. When the second anti-shake magnet 133 moves away from or approaches the second anti-shake coil 134, the magnetic attraction force between the second magnetic attraction member 1512 and the second anti-shake magnet 133 will form a magnetic return force on the second anti-shake magnet 133, which helps to reset the anti-shake carrier 121. The direction of the magnetic return force is opposite to the direction of the driving force formed by the magnetic attraction force between the second anti-shake magnet 133 and the second anti-shake coil 134.

[0178] When the second anti-shake magnet 133 is too far away from the second anti-shake coil 134, the driving force formed by the second anti-shake magnet 133 and the second anti-shake coil 134 decreases. Since the second magnetic attraction member 1512 has the second opening 1502 on the side away from the movement direction of the second anti-shake magnet 133, the magnetic attraction return force between the second magnetic attraction member 1512 and the second anti-shake magnet 133 can reduce the resistance of the magnetic attraction force between the second anti-shake magnet 133 and the second anti-shake coil 134 to the driving force.

[0179] It is also worth mentioning that, in an embodiment of the present application, the first magnetic attraction member 1511 and the second magnetic attraction member 1512 are respectively arranged on one side of the ball 1410 close to the middle, i.e. on one side of the ball 1410 arranged at the corner 1223 of the frame 122, for example, the first magnetic attraction member 1511 is arranged on one side of the ball 1410 arranged at the corner 1223 of the frame 122 in the second side of the base 111; the second magnetic attraction member 1512 is arranged on one side of the ball 1410 arranged at the corner 1223 of the frame 122 in the first side of the base 111. On the one hand, this is conducive to the overall magnetic attraction force applied to the anti-shake carrier 121 being located close to the ball 1410 arranged at the corner 1223 of the frame 122, thereby maintaining the adsorption stability of the anti-shake carrier 121 on the base 111 and reducing the risk of overturning of the anti-shake carrier 121; such an arrangement also provides space for arranging the sensing assembly 16 below the first anti-shake magnet 131 and the second anti-shake magnet 133, for example, the first side of the base 111 away from the ball 1410 arranged at the corner 1223 of the frame 122 can be arranged with components of the sensing assembly 16, and the second side of the base 111 away from the ball 1410 arranged at the corner 1223 of the frame 122 can be arranged with components of the sensing assembly 16.

[0180] In an embodiment of the present application, as shown in Figure 7 The anti-shake magnetic attraction piece 151 further comprises a magnetic attraction connecting member 1513 connected between the first magnetic attraction member 1511 and the second magnetic attraction member 1512, so that the first magnetic attraction member 1511 and the second magnetic attraction member 1512 can be installed together to simplify installation. It should be understood that in other embodiments of the present application, the anti-shake magnetic attraction piece 151 can not be provided with the magnetic attraction connecting member 1513.

[0181] As shown in Figure 9 The sensing assembly 16 comprises a focus sensing element 163, a first anti-shake sensing element 161 and a second anti-shake sensing element 162. The focus sensing element 163 is used to obtain position change information of the focus carrier 123 relative to the anti-shake carrier 121; the first anti-shake sensing element 161 and the second anti-shake sensing element 162 are used to obtain position change information of the anti-shake carrier 121 relative to the base 111.

[0182] In an embodiment of the present application, the focus sensing element 163 is opposite to the focus magnet 135, and the position change information of the focus magnet 135 is obtained by obtaining the magnetic field change information of the focus magnet 135, so as to obtain the position change information of the focus carrier 123 fixed by the focus magnet 135, and mainly obtain the position change information of the focus carrier 123 relative to the anti-shake carrier 121 along the optical axis direction D.

[0183] Further, the focus sensing element 163 is fixed to the anti-shake carrier 121, and can be arranged in the focus coil 136, for example, in the middle of the focus coil 136.

[0184] The first anti-shake sensing element 161 is arranged opposite to the bottom surface of the first anti-shake magnet 131, and the position change information of the first anti-shake magnet 131 is obtained by obtaining the magnetic field change information of the first anti-shake magnet 131, so as to obtain the position change information of the anti-shake carrier 121 fixed by the first anti-shake magnet 131, and mainly obtain the position change information of the anti-shake carrier 121 relative to the base 111 along the first axis direction D1.

[0185] Further, the first anti-shake sensing element 161 is located below the first anti-shake magnet 131 and is fixed to the base 111, and can be arranged on the side of the first magnetic attraction member 1511 away from the ball 1410 arranged at the corner 1223 of the frame 122.

[0186] The second anti-shake sensing element 162 is arranged opposite to the bottom surface of the second anti-shake magnet 133, and the position change information of the second anti-shake magnet 133 is obtained by obtaining the magnetic field change information of the second anti-shake magnet 133, so as to obtain the position change information of the anti-shake carrier 121 fixed by the second anti-shake magnet 133, and mainly obtain the position change information of the anti-shake carrier 121 relative to the base 111 along the second axis direction D2.

[0187] Further, the second anti-shake sensing element 162 is located below the second anti-shake magnet 133 and is fixed to the base 111, and can be arranged on the side of the second magnetic attraction member 1512 away from the ball 1410 arranged at the corner 1223 of the frame 122.

[0188] The focus sensing element 163, the first anti-shake sensing element 161 and the second anti-shake sensing element 162 can be a Hall sensor, an inductive encoder chip (i.e., an IC chip), or an inductive encoder chip matched with a capacitor, or a TMR.

[0189] As Figure 9As shown, the conductive assembly 17 includes an anti-shake circuit board 171, a focusing circuit board 172, and a base conductive insert 173. The base conductive insert 173 is embedded in the base 111 and includes a coil conductive insert group 1731 and a lead-out conductive insert group 1732. The coil conductive insert group 1731 is spaced apart from the lead-out conductive insert group 1732 in the optical axis direction D, and the coil conductive insert group 1731 is located above the lead-out conductive insert group 1732.

[0190] The lead-out conductive insert group 1732 is embedded in the base body 1111, one end is electrically connected to the anti-shake circuit board 171, and the other end is located on one side of the motor 10, and a pin group is formed by extending outward from the base 111, which is used for electrical connection with other components of the camera module, such as the photosensitive assembly 30. In an embodiment of the present application, the pin group is located on the first side of the motor 10.

[0191] The coil conductive insert group 1731 is embedded in the sidewall of the base 111, and both ends are exposed, one end is electrically connected to the first anti-shake coil 132 and the second anti-shake coil 134, and the other end is connected to the anti-shake circuit board 171, thereby being electrically connected to the lead-out conductive insert group 1732 through the anti-shake circuit board 171.

[0192] The anti-shake circuit board 171 is fixed to the base 111 and electrically connected to the anti-shake driving assembly 1310. The first anti-shake sensing element 161, the second anti-shake sensing element 162, and the anti-shake magnetic suction piece 151 are all fixed to the base 111 by being fixed to the anti-shake circuit board 171. The first anti-shake sensing element 161 and the second anti-shake sensing element 162 are also electrically connected to the anti-shake circuit board 171, and are electrically connected to other components of the camera module, such as the photosensitive assembly 30, through the electrical connection between the anti-shake circuit board 171 and the base conductive insert 173.

[0193] The focusing circuit board 172 is electrically connected to the focusing driving assembly 1320. Specifically, one end of the focusing circuit board 172 is fixed to the anti-shake carrier 121 and is electrically connected to the focusing coil 136 and the focusing sensing element 163; the other end of the focusing circuit board 172 is fixed to the base 111 and is electrically connected to the base conductive insert 173, thereby being electrically connected to other components of the camera module, such as the photosensitive assembly 30, through the base conductive insert 173.

[0194] It is worth mentioning that, since the anti-shake carrier 121 moves relative to the base 111 in the direction D perpendicular to the optical axis, the middle part of the focusing circuit board 172 used for connecting both ends needs to be deformed to reduce the resistance to the movement of the anti-shake carrier 121 relative to the base 111.

[0195] Correspondingly, in an embodiment of the present application, the focusing circuit board 172 comprises a conductive fixed part 1721, a conductive movable part 1722, and a conductive connecting part 1723. The conductive connecting part 1723 is connected between the conductive fixed part 1721 and the conductive movable part 1722.

[0196] The conductive movable part 1722 is one end of the focusing circuit board 172, is fixed to the outer surface of the side wall of the anti-shake carrier 121, is located at the fourth side of the motor 10, and is electrically connected with the focusing coil 136 and the focusing sensing element 163. The focusing magnetic sheet 152 and the focusing coil 136 are respectively arranged on both sides of the conductive movable part 1722. The focusing coil 136 and the focusing sensing element 163 are fixed and electrically connected to one side (inner side) of the conductive movable part 1722, so that the focusing coil 136 and the focusing sensing element 163 are fixed to the anti-shake carrier 121 through the fixing of the conductive movable part 1722; the focusing magnetic sheet 152 is fixed to the other side (outer side) of the conductive movable part 1722, so that the focusing magnetic sheet 152 is fixed to the anti-shake carrier 121 through the fixing of the conductive movable part 1722.

[0197] The conductive fixed part 1721 is the other end of the focusing circuit board 172, is fixed to the third base side wall 1114 of the base 111, is located at the third side of the motor 10, and is connected with the base conductive insert 173, so as to be electrically connected with other components of the camera module, such as the photosensitive assembly 30, through the base conductive insert 173.

[0198] The conductive movable part 1722 and the conductive fixed part 1721 extend in the vertical direction, and the conductive connecting part 1723 is bent in the horizontal direction with respect to the conductive fixed part 1721 and the conductive movable part 1722, respectively. Correspondingly, the conductive connecting part 1723 extends on the top surface of the base 111. Specifically, one end of the conductive connecting part 1723 is bently connected with the conductive movable part 1722 at the fourth side of the motor 10, the conductive connecting part 1723 extends from the fourth side of the motor 10 to the first side, to the second side, to the third side, and the other end of the conductive connecting part 1723 is bently connected with the conductive fixed part 1721 at the third side of the motor 10.

[0199] Accordingly, in an embodiment of the present application, at least part of the focusing circuit board 172 (i.e. the conductive connection portion 1723) extends above the base 111 in a horizontal direction.

[0200] The conductive movable portion 1722 is adjacent to the conductive fixed portion 1721, and is located at the fourth side and the third side of the motor 10, respectively. The conductive connection portion 1723 extends in a meandering manner from a portion of the fourth side, the first side, the second side and the third side of the top of the motor 10, so that the length of the conductive connection portion 1723 is increased, thereby reducing the influence of the focusing circuit board 172 on the optical image stabilization function.

[0201] In a variant embodiment of the present application, as shown in FIGS. 20 to Figure 22 As shown, the focusing circuit board 172 only includes the conductive movable portion 1722 and the conductive connection portion 1723, and does not include the conductive fixed portion 1721 located at the third bottom side wall 1114 of the base 111. The focusing circuit board 172 extends at least partially above the carrier assembly 110 in a horizontal direction. In the present application, the part of the focusing circuit board 172 extending above the carrier assembly 110 in a horizontal direction is defined as the conductive connection portion 1723.

[0202] In this variant embodiment, the conductive connection portion 1723 extends along at least two sides of the carrier assembly 110, for example, the conductive connection portion 1723 extends along the fourth side, the first side, the second side and the third side of the motor in sequence. The fourth side of the motor is provided with the focusing drive assembly 1320. The third side of the motor is not provided with the anti-shake drive assembly 1310. Accordingly, the conductive connection portion 1723 extends along the circumference of the motor from the side provided with the focusing drive assembly 1320 to the side not provided with the anti-shake drive assembly 1310; more specifically, the conductive connection portion 1723 extends along the circumference of the motor from the side provided with the focusing coil 136 to the side not provided with the anti-shake coil and the anti-shake magnet.

[0203] The conductive connection portion 1723 includes a first end portion 1710, a second end portion 1720 and an intermediate extension portion 1730 between the first end portion 1710 and the second end portion 1720. The first end portion 1710 of the conductive connection portion 1723 is fixed to the top surface of the sidewall of the anti-shake carrier 121, located at the fourth side of the motor 10, and connected to the conductive movable portion 1722. The second end portion 1720 forms one end of the focusing circuit board 172, is fixed to the top surface of the third base sidewall 1114 of the base 111, located at the third side of the motor 10, and connected to the base conductive insert 173, so as to be electrically connected to other components of the camera module, such as the photosensitive assembly 30, through the base conductive insert 173. At least part of the base conductive insert 173 extends from the base body 1111 to the third base sidewall 1114, and then to the second end portion 1720 of the conductive connection portion 1723. Further, at least part of the portion where the base conductive insert 173 is connected to the second end portion 1720 of the conductive connection portion 1723 extends in the horizontal direction, which on one hand can increase the contact area with the conductive connection portion 1723, and on the other hand facilitates exposing a sufficient area outside the base 111 to form an electrical connection end.

[0204] The conductive movable portion 1722 forms the other end of the focusing circuit board 172, extends in the vertical direction, is fixed to the outer surface of the sidewall of the anti-shake carrier 121, and is located at the fourth side of the motor 10, and is electrically connected to the focusing coil 136 and the focusing sensing element 163. The focusing magnetic sheet 152 and the focusing coil 136 are respectively arranged on the two sides of the conductive movable portion 1722. The focusing coil 136 and the focusing sensing element 163 are fixed and electrically connected to one side (inner side) of the conductive movable portion 1722, so that the focusing coil 136 and the focusing sensing element 163 are fixed to the anti-shake carrier 121 through the fixing of the conductive movable portion 1722; the focusing magnetic sheet 152 is fixed to the other side (outer side) of the conductive movable portion 1722, so that the focusing magnetic sheet 152 is fixed to the anti-shake carrier 121 through the fixing of the conductive movable portion 1722.

[0205] It is worth mentioning that if the conductive movable part 1722 and the conductive connecting part 1723 are formed by bending a whole piece of circuit board, due to the influence of bending resilience, the conductive connecting part 1723 and the conductive movable part 1722 have a mutual trend of moving away from each other, which is that the conductive connecting part 1723 has a trend of upwarping and the conductive movable part 1722 has a trend of outward warping. Based on this, in this variant embodiment, the conductive movable part 1722 and the first end part 1710 of the conductive connecting part 1723 are not integrally formed, but are connected together by welding, bonding or the like. In this way, to a certain extent, the first end part 1710 of the conductive connecting part 1723 can be prevented from being affected by bending resilience to upwarp, and the conductive movable part 1722 can be prevented from being affected by bending resilience to outward warp. Specifically, the bottom surface of the first end part 1710 of the conductive connecting part 1723 and the top surface of the conductive movable part 1722 are connected together by welding, bonding or the like. In an example of the present application, the first end part 1710 of the conductive connecting part 1723 is fixed to the top surface of the side wall of the fourth side of the anti-shake carrier 121 and protrudes from the anti-shake carrier 121 in the horizontal direction, so that the first end part 1710 of the conductive connecting part 1723 has sufficient area to fully contact and connect with the conductive movable part 1722.

[0206] It should be understood that in other embodiments of the present application, the conductive movable part 1722 and the conductive connecting part 1723 can be designed to be integrally formed by bending a whole piece of circuit board.

[0207] At least part of the conductive connecting part 1723 corresponds to the chamfered corner part of the motor 10, which is a chamfered corner turning part 1724, forming an obtuse angle turning to avoid too small turning angle, which helps to reduce the resistance when the anti-shake carrier 121 moves relative to the base 111, and at the same time, can reduce the risk of cracking of the conductive connecting part 1723 at the turning, thereby reducing the risk of damage at the corner of the focusing circuit board 172.

[0208] Correspondingly, the conductive connecting part 1723 extends between different sides of the motor and forms a bevel corner turning part 1724 between the parts extending on different sides. The horizontal outer edge line located on one side of the motor and the horizontal outer edge line located on the other side of the motor in the bevel corner turning part 1724 form an obtuse angle with the horizontal outer edge line between them; for example, in the bevel corner turning part 1724 located at the fourth corner of the motor, the horizontal outer edge line between the horizontal outer edge line located on the fourth side of the motor and the horizontal outer edge line located on the first side of the motor forms an obtuse angle with the horizontal outer edge line located on the fourth side of the motor and the horizontal outer edge line located on the first side of the motor respectively; in the bevel corner turning part 1724 located at the first corner of the motor, the horizontal outer edge line between the horizontal outer edge line located on the first side of the motor and the horizontal outer edge line located on the second side of the motor forms an obtuse angle with the horizontal outer edge line located on the first side of the motor and the horizontal outer edge line located on the second side of the motor respectively; in the bevel corner turning part 1724 located at the second corner of the motor, the horizontal outer edge line between the horizontal outer edge line located on the second side of the motor and the horizontal outer edge line located on the third side of the motor forms an obtuse angle with the horizontal outer edge line located on the second side of the motor and the horizontal outer edge line located on the third side of the motor respectively.

[0209] It is worth mentioning that the conductive connecting part 1723 can be made of a flexible circuit board, which can be a piece of flexible circuit board or a plurality of flexible circuit boards cut from a flexible circuit board; the conductive connecting part 1723 can also be directly formed by a plurality of conductive metal wires, and the conductive metal wires are wrapped with insulating materials to avoid short circuit.

[0210] Correspondingly, in an embodiment of the present application, the conductive connecting part 1723 includes at least two parts spaced in the circumferential direction. The conductive connecting part 1723 further includes at least one connecting flap 1726, wherein the connecting flap 1726 is located between each adjacent two parts spaced in the circumferential direction. Further, the connecting flap 1726 is located at the corner of the motor, which is the intersection of different sides of the motor, for example, the intersection of the first side and the second side of the motor is the first corner of the motor, the intersection of the second side and the third side of the motor is the second corner of the motor, the intersection of the third side and the fourth side of the motor is the third corner of the motor, and the intersection of the fourth side and the first side of the motor is the fourth corner of the motor.

[0211] In an embodiment of the present application, the conductive connection portion 1723 includes a conductive connection wire 1725, and a gap is provided in the conductive connection wire 1725 of the conductive connection portion 1723, so that one complete conductive connection wire 1725 is divided into a plurality of (two or more) conductive connection wires 1725. The conductive connection portion 1723 further includes a connecting joint 1726 provided at the plurality of conductive connection wires 1725, so that the plurality of conductive connection wires 1725 move or deform together.

[0212] In another embodiment of the present application, the plurality of conductive connection wires 1725 in the conductive connection portion 1723 are arranged in the circumferential direction of the motor.

[0213] The number of the conductive connection wires 1725 is set according to requirements. In consideration of the fact that the focus sensing element 163 also needs to be conductive through the focus circuit board 172, in some embodiments, the conductive connection portion 1723 includes at least two conductive connection wires 1725, for example, two, four or six conductive connection wires 1725, which is related to the specific model of the focus sensing element 163 and the connection mode of the focus sensing element 163 and the focus coil 136.

[0214] In another embodiment of the present application, the plurality of conductive connection wires 1725 in the conductive connection portion 1723 are arranged in parallel, more specifically, the straight line portions corresponding to each other in the radial direction of the plurality of conductive connection wires 1725 are parallel to each other, and the curved line portions corresponding to each other in the radial direction of the plurality of conductive connection wires 1725 are concentric circles.

[0215] In some embodiments, the conductive connection portion 1723 further includes a glue layer and an insulating layer, the insulating layer is wrapped outside the conductive connection wire 1725 (i.e., the conductive metal wire), and the glue layer is located between the conductive metal wire and the insulating layer and is used to bond and fix the two. The provision of the insulating layer and the glue layer can increase the structural strength of the conductive metal wire. In some embodiments, the insulating layer is formed of a polyimide film.

[0216] It should be understood that, in the present application, the height dimension of the conductive connection portion 1723 in the optical axis direction D is much smaller than the width dimension and the length dimension of the conductive connection portion 1723 in the horizontal direction, the conductive connection portion 1723 is horizontally arranged above the base 111 in a flat shape, the height is small, and the height of the motor 10 is not increased too much. Even if the motor original height space is used to arrange the conductive connection portion 1723 by reducing part of the material of the anti-shake carrier 121 or the base 111, the height of the motor 10 is not increased. In particular, the plane where the conductive connection portion 1723 is located is perpendicular or close to perpendicular to the plane where the anti-shake coil is located. The conductive connection portion 1723 extends on the top surface of the base 111 and is located above the anti-shake coil. At this time, because the conductive connection portion 1723 is horizontally arranged, the height of the motor 10 is less affected, which is beneficial to realize the shoulder height and miniaturization of the motor 10 and the camera module. Assuming that the conductive connection portion 1723 is vertically arranged, when it is located above the anti-shake coil, the height of the motor 10 is significantly increased, and when it is located outside the anti-shake coil, the transverse dimension of the motor 10 is increased.

[0217] The orthographic projection of the conductive connection portion 1723 in the optical axis direction D at least partially overlaps the first anti-shake coil 132 and the second anti-shake coil 134. Further, the orthographic projection of the conductive connection portion 1723 in the optical axis direction D does not exceed the first anti-shake coil 132 and the second anti-shake coil 134 in the width direction. In this way, the conductive connection portion 1723 can occupy less additional transverse dimension (beyond the anti-shake carrier 121 and the anti-shake coil).

[0218] The orthographic projection of the conductive connection portion 1723 in the optical axis direction D does not overlap the focusing carrier 123 at all, so as to avoid interference between the focusing carrier 123 and the focusing circuit board 172 when the focusing carrier 123 moves along the optical axis direction D.

[0219] The orthographic projection of the conductive connection portion 1723 in the optical axis direction D at least partially overlaps the anti-shake carrier 121 and the base 111. The area of the portion of the orthographic projection of the conductive connection portion 1723 that overlaps the base 111 is greater than the area of the portion that overlaps the anti-shake carrier 121. In other words, most of the area of the conductive connection portion 1723 is above the base 111. In this way, the risk of the anti-shake carrier 121 hitting the focusing circuit board 172 and causing the focusing circuit board 172 to deform or be damaged after the anti-shake carrier 121 is separated from the base 111 due to accidental impact on the motor can be reduced.

[0220] In the present application, the conductive connecting portion 1723 needs to have a small elastic coefficient (K value) in the horizontal direction, so that the conductive connecting portion 1723 can be deformed under the action of a small force, thereby reducing the resistance to lateral deformation and the influence on the anti-shake function. In the optical axis direction D, i.e. the height direction, the conductive connecting portion 1723 needs to have a large elastic coefficient (K value), so that the part of the conductive connecting portion 1723 away from the conductive movable portion 1722 and the conductive fixed portion 1721 is not prone to sag, thereby reducing the friction between the conductive connecting portion 1723 and the base 111.

[0221] It should be understood that it is difficult to keep the K value of the conductive connecting portion 1723 small in the horizontal direction and not low in the optical axis direction D, so a protrusion can be provided on the top surface of the base 111 corresponding to the position of the conductive connecting portion 1723, thereby avoiding direct contact between the conductive connecting portion 1723 and the top surface of the base 111. This can reduce the vibration, wear or deformation of the conductive connecting portion 1723.

[0222] Correspondingly, in an embodiment of the present application, the top surface of the base 111 is provided with at least one top surface protrusion 1116, and at least part of the conductive connecting portion 1723 is supported by the top surface protrusion 1116, so as to avoid the part of the conductive connecting portion 1723 away from the conductive movable portion 1722 and the conductive fixed portion 1721 from sagging and contacting and rubbing with the base 111. The conductive connecting portion 1723 is basically suspended above the base 111 under the support of the top surface protrusion 1116.

[0223] In the embodiment of the present application, the conductive connecting portion 1723 is not provided with the conductive fixed portion 1721, and the middle extension portion 1730 of the conductive connecting portion 1723 is supported by the top surface protrusion 1116, so as to reduce the risk of the part of the conductive connecting portion 1723 away from the first end portion 1710 and the second end portion 1720 from sagging and directly contacting with the base 111, so as to cope with the vibration, wear and deformation of the focusing circuit board 172.

[0224] The top surface protrusion 1116 can be formed on the top surface of the base 111 by integrally forming with the base 111, bonding parts, or directly applying glue, etc. Preferably, the top surface protrusion 1116 is directly formed by applying glue, i.e. the glue after curing forms the top surface protrusion 1116. On the one hand, the height of the top surface protrusion 1116 directly formed by applying glue can be controlled to be lower, on the other hand, when a plurality of top surface protrusions 1116 are provided, it is also helpful to maintain the consistency of the plurality of top surface protrusions 1116, and the surface of the top surface protrusion 1116 formed by curing of the glue is generally smoother and has smaller friction. And the top surface protrusion 1116 formed by curing of the glue has a certain elasticity, which can play a certain role in vibration reduction and deformation buffering. The glue is preferably UV (ultraviolet) curing glue.

[0225] It should be understood that in other embodiments of the present application, the top surface protrusion 1116 can not be provided.

[0226] It is worth mentioning that in the embodiment of the present application, the focusing circuit board 172 includes the conductive fixed part 1721, the motor further includes a first pressing part 191 and a second pressing part 192. The first pressing part 191 is provided on the outer side of the conductive fixed part 1721, a part thereof extends in the vertical direction as a first vertical part 1911, and is located on the outer side of the conductive fixed part 1721, and another part thereof is bent in the horizontal direction relative to the part extending in the vertical direction as a first horizontal part 1912, and is located above the conductive connecting part 1723, and can exert pressure on the part where the conductive connecting part 1723 is connected with the conductive fixed part 1721 to a certain extent, preventing the conductive connecting part 1723 from being upwardly warped relative to the conductive fixed part 1721. The second pressing part 192 is provided on the outer side of the conductive movable part 1722, a part thereof extends in the vertical direction as a second vertical part 1921, and is located on the outer side of the conductive movable part 1722, and another part thereof is bent in the horizontal direction relative to the part extending in the vertical direction as a second horizontal part 1922, and is located above the conductive connecting part 1723, and can exert pressure on the part where the conductive connecting part 1723 is connected with the conductive movable part 1722 to a certain extent, preventing the conductive connecting part 1723 from being upwardly warped relative to the conductive movable part 1722.

[0227] In addition, in an embodiment of the present application, the first pressing member 191 and the second pressing member 192 are connected to the conductive connecting portion 1723 and spaced apart from the top surface of the base in the height direction of the motor, so that the conductive connecting portion 1723, especially the region of the conductive connecting portion 1723 adjacent to the first pressing member 191 and the second pressing member 192, is suspended relative to the top surface of the base to a certain extent.

[0228] It is worth mentioning that, in an embodiment of the present application, the side of the conductive fixed portion 1721 and the first pressing member 191 is opposite to the side of the second anti-shake coil 134 and the second anti-shake magnet 133; the side of the conductive movable portion 1722 and the second pressing member 192 is opposite to the side of the first anti-shake coil 132 and the first anti-shake magnet 131. When the anti-shake carrier 121 is driven along the second axis direction D2 to the side (i.e., the third side) of the conductive fixed portion 1721 of the motor, especially when it is driven to the farthest stroke in the second axis direction D2, due to the constraint of the first pressing member 191 to the outer side of the conductive fixed portion 1721 and the constraint of the first pressing member 191 to the upper side of the conductive connecting portion 1723, the part of the conductive connecting portion 1723 opposite to the first horizontal portion 1912 in the optical axis direction D (i.e., the first deformable corresponding portion 17231) is bent upwards, as shown in Figure 18 , and generates a rebound force that drives the anti-shake carrier 121 to move along the second axis direction D2 to the side (i.e., the first side) opposite to the side where the first pressing member 191 is located, which helps to improve the speed of the anti-shake carrier 121 returning to its initial position (i.e., the position when it is not driven, approximately centered), thereby helping to improve the response speed of the anti-shake.

[0229] When the anti-shake carrier 121 is driven along the first axis direction D1 to the side (i.e., the fourth side) of the conductive movable portion 1722 of the motor, especially when it is driven to the farthest stroke in the first axis direction D1, due to the constraint of the second pressing member 192 to the outer side of the conductive movable portion 1722 and the constraint of the second pressing member 192 to the upper side of the conductive connecting portion 1723, the part of the conductive connecting portion 1723 opposite to the second horizontal portion 1922 in the optical axis direction D is bent upwards, as shown in Figure 19 , and generates a rebound force that drives the anti-shake carrier 121 to move along the first axis direction D1 to the side (i.e., the second side) opposite to the side where the second pressing member 192 is located, which helps to improve the speed of the anti-shake carrier 121 returning to its initial position (i.e., the position when it is not driven, approximately centered), thereby helping to improve the response speed of the anti-shake.

[0230] Correspondingly, in an embodiment of the present application, the part of the conductive connecting portion 1723 opposite to the first horizontal portion 1912 in the optical axis direction D forms a first deformable corresponding portion 17231 adapted to elastically deform, and the first horizontal portion 1912 is spaced apart from the first deformable corresponding portion 17231 in the optical axis direction D, which is structurally manifested as that the distance between the first horizontal portion 1912 and the top surface of the base 111 in the optical axis direction D is greater than the thickness (i.e. the size in the optical axis direction D) of the first deformable corresponding portion 17231 to provide a deformation space for the first deformable corresponding portion 17231. The part of the conductive connecting portion 1723 opposite to the second horizontal portion 1922 in the optical axis direction D forms a second deformable corresponding portion 17232 adapted to elastically deform, and the second horizontal portion 1922 is spaced apart from the second deformable corresponding portion 17232 in the optical axis direction D, which is structurally manifested as that the distance between the second horizontal portion 1922 and the top surface of the base 111 in the optical axis direction D is greater than the thickness (i.e. the size in the optical axis direction D) of the second deformable corresponding portion 17232 to provide a deformation space for the second deformable corresponding portion 17232.

[0231] It can be understood that the present application uses the current reversal of the anti-shake coil to realize the reverse movement of the anti-shake carrier, but when the distance between the anti-shake coil and the anti-shake magnet becomes larger, the magnetic attraction force between the two will become weaker, at which time it is more difficult to attract the anti-shake magnet to the position close to the anti-shake coil. Therefore, the elastic force generated by the bending of the focusing circuit board 172 located on the side opposite to the anti-shake coil pushes the anti-shake carrier 121 back.

[0232] Specifically, the side of the anti-shake magnet facing the anti-shake coil is a single magnetic pole (N or S), and after the anti-shake coil generates the same magnetic pole as the magnetic pole of the side of the anti-shake magnet facing the anti-shake coil after being powered on, the anti-shake coil drives the anti-shake magnet to move away from the anti-shake coil, and after the anti-shake coil generates a magnetic pole opposite to the magnetic pole of the side of the anti-shake magnet facing the anti-shake coil, the anti-shake coil drives the anti-shake magnet to move close to the anti-shake coil. At this time, when the distance between the anti-shake magnet and the anti-shake coil becomes larger, the acting force between the two will become weaker, and the anti-shake coil is insufficient to attract the anti-shake magnet, making it difficult to drive the anti-shake carrier 121 to reset. At this time, the anti-shake magnet is made to move close to the anti-shake coil by bending the focusing circuit board 172 under the pressing member, so as to achieve the resetting effect of the anti-shake carrier 121.

[0233] The first and second deformable corresponding parts 17231 and 17232 of the focusing circuit board 172 need to be bent, so the focusing circuit board 172 is not fixed to the top surface of the base 111, the conductive fixed part 1721 is fixed to the first vertical part 1911, and the conductive movable part 1722 is fixed to the second vertical part 1921.

[0234] The bending directions of the horizontally bent parts of the two pressing parts relative to the vertically extended parts are parallel to the ball grooves on the bottom side of the anti-shake carrier 121 and the ball grooves on the top side of the anti-shake carrier 121. By using the directions of the ball grooves, the elastic force generated by the bending of the focusing circuit board 172 can be well limited to act on the anti-shake carrier 121.

[0235] For example, the first horizontal part 1912 of the first pressing part 191 is bent relative to the first vertical part 1911 along the second axis direction D2, and the second horizontal part 1922 of the second pressing part 192 is bent relative to the second vertical part 1921 along the first axis direction D1.

[0236] When the ball grooves on the top side of the frame 122 (i.e., the frame top surface ball grooves 1224) and the ball grooves on the bottom side of the anti-shake carrier 121 (i.e., the carrier ball grooves 1211) extend along the second axis direction D2, and the ball grooves on the bottom side of the frame 122 (i.e., the frame bottom surface ball grooves 1225) and the ball grooves on the top side of the base 111 (i.e., the base ball grooves 1115) extend along the first axis direction D1, the bending direction of the first horizontal part 1912 of the first pressing part 191 relative to the first vertical part 1911 is consistent with the extending directions of the frame top surface ball grooves 1224 and the carrier ball grooves 1211, and the elastic force provided by the first horizontal part 1912 facilitates the relative sliding of the frame 122 and the anti-shake carrier 121 by the guiding action of the frame top surface ball grooves 1224 and / or the carrier ball grooves 1211, thereby facilitating the resetting of the anti-shake carrier 121 along the second axis direction D2; the bending direction of the second horizontal part 1922 of the second pressing part 192 relative to the second vertical part 1921 is consistent with the extending directions of the frame bottom surface ball grooves 1225 and the base ball grooves 1115, and the elastic force provided by the second horizontal part 1922 facilitates the relative sliding of the base 111 and the anti-shake carrier 121 by the guiding action of the frame bottom surface ball grooves 1225 and / or the base ball grooves 1115, thereby facilitating the resetting of the anti-shake carrier 121 along the first axis direction D1.

[0238] It is worth mentioning that the second pressing piece 192 and the focusing magnetic attraction piece 152 can be the same element, in other words, the second pressing piece 192 can be used as the focusing magnetic attraction piece 152, or the focusing magnetic attraction piece 152 can be used as the second pressing piece. Correspondingly, the focusing magnetic attraction piece 152 is arranged outside the conductive movable part 1722, a part of which extends in the vertical direction, and another part of which is bent in the horizontal direction relative to the part extending in the vertical direction and is connected above the conductive connecting part 1723, which can exert pressure on the part connecting the conductive connecting part 1723 and the conductive movable part 1722 to a certain extent, preventing the conductive connecting part 1723 from being upwardly warped relative to the conductive movable part 1722.

Since the first anti-shake sensing element 161 and the second anti-shake sensing element 162 are directly mounted at different positions of the anti-shake circuit board 171, the electrical connection structure between the first anti-shake sensing element 161 and the anti-shake circuit board 171 and the electrical connection structure between the second anti-shake sensing element 162 and the anti-shake circuit board 171 do not interfere with each other in space.

The electrical connection structure between the second anti-shake sensing element 162 and the anti-shake circuit board 171 and the electrical connection structure between the second anti-shake coil 134 and the anti-shake circuit board 171 do not interfere with each other in space.

[0244] It is worth mentioning that in the present application, the focusing circuit board 172 is located on the fourth side of the anti-shake carrier 121, i.e., the side without the base side wall, and the upper side of the base 111 and the outer side of the side wall of the base 111, close to the outer side of the motor 10, for electrical connection with the base conductive insert 173, without the need to additionally set a transverse conductive structure from the inside of the motor 10 close to the center to the side wall of the base 111 to guide outward through multiple internal structures, so as to electrically connect the focusing circuit board 172 to the base conductive insert 173.

[0245] The part of the coil conductive insert group 1731 for electrically connecting the first anti-shake coil 132 and the part for electrically connecting the second anti-shake coil 134 are also close to the outer side of the motor 10, for electrical connection with the anti-shake circuit board 171.
