Description

Technical Field

[0001] This application relates to the field of photography, and more specifically, to camera modules and their motors. Background Technology

[0002] Camera modules are indispensable components in electronic devices such as mobile phones and tablets, used to meet shooting needs. To ensure shooting quality, camera modules are usually equipped with optical autofocus (AF) or optical image stabilization (OIS). The realization of optical image stabilization and optical autofocus both rely on motors driving the movement of the lens components.

[0003] As consumers' demands for image quality continue to rise, the image stabilization performance of camera modules is becoming increasingly crucial. For example, during video recording, device shake can cause blurry images, severely reducing the quality of the video. Especially in telephoto shooting mode, even minor device shake can be significantly amplified, causing violent shaking in the footage. Furthermore, when using digital zoom, the image shake problem is further exacerbated, seriously affecting the shooting experience.

[0004] Therefore, designing motors and camera modules with good image stabilization performance has become an urgent need in the current market.

[0005] Furthermore, miniaturization and thinning are inevitable development trends in electronic devices such as mobile phones and tablets. The design of camera modules also needs to meet the characteristics of small size to adapt to the miniaturization trend in electronic devices such as mobile phones and tablets.

Detailed Implementation

[0068] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0069] Camera modules are required to meet the demands of small size while simultaneously fulfilling diverse functionalities such as optical image stabilization and autofocus. To achieve this, various components are needed. Theoretically, this leads to an increasing number of components, making the camera module's structure more complex and its overall size and weight difficult to control within a defined range—a situation that contradicts the requirement for a small size.

[0070] like Figures 1 to 14 and Figures 15 to 17 As shown, a camera module and a motor 10 for the camera module according to an embodiment of this application are illustrated.

[0071] Specifically, such as Figure 14 As shown, 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 light-sensing 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, so as to realize the functions of autofocus and optical image stabilization.

[0072] The photosensitive component 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 emitted from the lens assembly 20. In one specific example, the photosensitive chip is fixed to the side of the chip circuit board facing the lens assembly 20. The at least one electronic component can be implemented as a passive electronic device such as a capacitor or resistor, or an active electronic device such as a diode or a memory chip, and the at least one electronic component can be disposed on the 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 via at least one lead.

[0073] In some examples of this application, the camera module further includes a light filter assembly disposed on the light-sensing path of the photosensitive component 30, allowing the camera module to filter out unwanted stray light (e.g., infrared light). For example, the light filter assembly is disposed between the lens assembly 20 and the photosensitive component 30. In one specific example, the light filter assembly includes a bracket and a filter element. The bracket is supported on the chip circuit board, and the filter element is fixed to the bracket.

[0074] The motor 10 has four sides, which, in this application, are defined as a first side, a second side, a third side, and a fourth side in a counterclockwise direction. Correspondingly, the four sides of each component of the motor 10 are consistent with the four sides defined for 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 for the lens assembly 20. In this application, two mutually perpendicular axes perpendicular to the optical axis L are defined as a first axis and a 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. Correspondingly, the first axis direction D1 and the second axis direction D2 are respectively perpendicular to the optical axis direction D, and the first axis direction D1 and the second axis direction D2 are mutually perpendicular.

[0075] The motor 10 includes a fixed component 11, a movable component 12, a drive component 13, a support component 14, a magnetic attraction component 15, a sensing component 16, and a conductive component 17. The movable component 12 carries the lens assembly 20 and is movably disposed within the fixed component 11. The drive component 13 drives the movable component 12 to move relative to the fixed component 11. The support component 14 supports and guides the components within the movable component 12. The magnetic attraction component 15 attracts the components within the movable component 12 to ensure its motion stability. The sensing component 16 acquires positional change information of the components within the movable component 12. The conductive component 17 is connected to the drive component 13 to enable electrical conduction in the drive component 13.

[0076] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the fixing assembly 11 includes a base 111 and a top cover 112, wherein the top cover 112 and the base 111 are interlocked and fixed together to form a receiving cavity 101 located between the base 111 and the top cover 112. The receiving cavity 101 is used to accommodate other components. The base 111 and the movable assembly 12 form a carrier assembly 110 for supporting the lens assembly 20.

[0077] In this embodiment, the base 111 includes a base body 1111 and three base sidewalls extending upward from three sides of the base body 1111. The base body 1111 mainly provides bottom support. The three base sidewalls are a first base sidewall 1112, a second base sidewall 1113, and a third base sidewall 1114. The first base sidewall 1112, the second base sidewall 1113, and the third base sidewall 1114 are located on the first, second, and third sides of the motor 10, respectively. The first base sidewall 1112 and the third base sidewall 1114 are arranged opposite each other and are located on both sides of the second base sidewall 1113. Specifically, the first base sidewall 1112 and the third base sidewall 1114 are opposite each other in the second axial direction D2.

[0078] It is worth mentioning that in this application, the base 111 does not have a sidewall on the fourth side, which can reduce the lateral dimension of the motor 10 to a certain extent.

[0079] The movable component 12 includes an image stabilization carrier 121 and a focusing carrier 123. The image stabilization carrier 121 is movably mounted within the receiving cavity 101 of the fixed component 11. More specifically, the image stabilization carrier 121 is movably mounted within the base 111. The image stabilization carrier 121 is configured to move relative to the fixed component 11 along a first axial direction D1 and a second axial direction D2, thereby causing the focusing carrier 123 to move along the first axial direction D1 and the second axial direction D2. The focusing carrier 123 is movably mounted within the image stabilization carrier 121 and configured to mount a lens assembly 20 therein. In other words, the lens assembly 20 is fixed to the focusing carrier 123; the image stabilization carrier 121 indirectly carries the lens assembly 20 through the focusing carrier 123; and the focusing carrier 123 moves together with the image stabilization carrier 121 relative to the base 111 in a direction perpendicular to the optical axis. The focusing carrier 123 is also configured to move relative to the image stabilizing carrier 121 along a set optical axis direction D.

[0080] In one embodiment of this application, such as Figure 2As shown, the movable component 12 further includes a frame 122 disposed between the image stabilization carrier 121 and the base 111. The frame 122 and the image stabilization carrier 121 are adapted to move relative to the base 111 along a first axial direction D1 perpendicular to the optical axis, thereby causing the focusing carrier 123 and the lens assembly 20 to move relative to the base 111 along the first axial direction D1 perpendicular to the optical axis. The image stabilization carrier 121 is adapted to move relative to the frame 122 along a second axial direction D2 perpendicular to the optical axis, thereby causing the focusing carrier 123 and the lens assembly 20 to move relative to the base 111 along the second axial direction D2 perpendicular to the optical axis. The arrangement of the frame 122 decomposes the movement of the image stabilization carrier 121 relative to the base 111 into two perpendicular movements, thereby reducing the risk of the image stabilization carrier 121 rotating around the optical axis relative to the base 111 and achieving more precise image stabilization.

[0081] It should be understood that in other embodiments of this application, the image stabilization carrier 121 may be designed to move relative to the frame 122 and the base 111 along a first axial direction D1 perpendicular to the optical axis, thereby driving the focusing carrier 123 and the lens assembly 20 to move relative to the frame 122 and the base 111 along the first axial direction D1 perpendicular to the optical axis; the image stabilization carrier 121 and the frame 122 may be designed to move relative to the base 111 along a second axial direction D2 perpendicular to the optical axis, thereby driving the focusing carrier 123 and the lens assembly 20 to move relative to the base 111 along the second axial direction D2 perpendicular to the optical axis.

[0082] In one embodiment of this application, at least a portion of the frame 122 is housed within the image stabilization carrier 121 to reduce the additional height space occupied by the frame 122, thereby reducing the height of the camera module to a certain extent. Specifically, the image stabilization carrier 121 has a lower receiving groove 1213, which is recessed upward from the bottom surface of the image stabilization carrier 121. At least a portion of the frame 122 is housed within the lower receiving groove 1213. In one example of this application, the bottom surface of the frame 122 does not extend beyond the bottom surface of the image stabilization carrier 121, structurally manifested as follows: the bottom surface of the frame 122 is flush with or higher than the bottom surface of the image stabilization carrier 121.

[0083] It's worth noting that the height dimension of a camera module has a significant impact on its overall performance. Therefore, any design that reduces the height of the camera module is crucial for its application. For example, camera modules are used in mobile phones, and when installed, their height is aligned with the phone's thickness. However, with the market demand for thinner and lighter phones, which are becoming increasingly thinner (approximately 0.5 cm), the available height space for the camera module is extremely limited. Therefore, the height of the camera module should be minimized as much as possible during its design.

[0084] It should also be understood that in other embodiments of this application, the active component 12 may not include the frame 122, and the anti-shake carrier 121 may be directly mounted on the base 111.

[0085] The drive assembly 13 is used to drive the focusing carrier 123 to move relative to the image stabilization carrier 121 along the optical axis direction D, and to drive the image stabilization carrier 121 to move relative to the base 111 in a direction perpendicular to the optical axis direction D.

[0086] Accordingly, in one embodiment of this application, as Figure 2 As shown, the driving assembly 13 includes an image stabilization driving assembly 1310 and a focus driving assembly 1320. The image stabilization driving assembly 1310 is configured to drive the image stabilization carrier 121 to move relative to the fixed assembly 11 along the first axis direction D1 and the second axis direction D2, and through the image stabilization carrier 121, drive the focus carrier 123 and the lens assembly 20 to move along the first axis direction D1 and the second axis direction D2, thereby performing optical image stabilization. The focus driving assembly 1320 is configured to drive the focus carrier 123 to move relative to the image stabilization carrier 121 along the optical axis direction D, thereby driving the lens assembly 20 to move relative to the image stabilization carrier 121 along the optical axis direction D, thereby performing autofocus. It is worth mentioning that in some embodiments, the focusing carrier 123 is fixed to all the optical lenses of the lens assembly 20, thereby realizing the optical focusing function; in other embodiments, the focusing carrier 123 is fixed only to some 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 component 30, thereby realizing the optical focusing function.

[0087] Furthermore, in one embodiment of this application, the image stabilization drive assembly 1310 is configured to drive the image stabilization carrier 121 to move relative to the fixing assembly 11 along the first axis direction D1, thereby causing the frame 122, the focusing carrier 123, and the lens assembly 20 to move along the first axis direction D1; it is also configured to drive the image stabilization carrier 121 to move relative to the frame 122 and the fixing assembly 11 along the second axis direction D2, thereby causing the focusing carrier 123 and the lens assembly 20 to move along the second axis direction D2.

[0088] It should be understood that in other embodiments of this application, the image stabilization drive component 1310 may be configured to drive the image stabilization carrier 121 to move relative to the frame 122 along the first axis direction D1, thereby causing the focusing carrier 123 and the lens assembly 20 to move along the first axis direction D1; and may also be configured to drive the image stabilization carrier 121 to move relative to the fixing component 11 along the second axis direction D2, thereby causing the frame 122, the focusing carrier 123 and the lens assembly 20 to move along the second axis direction D2.

[0089] It is worth mentioning that, in this application, the focusing drive assembly 1320 and the focusing carrier 123 for autofocus are disposed inside the image stabilization drive assembly 1310 and the image stabilization carrier 121 for optical image stabilization. This design helps to improve the accuracy of autofocus, the flexibility of the optical image stabilization component arrangement, and the accuracy of optical image stabilization. The terms "inner" and "outer" in this application are defined relative to the optical axis of the lens assembly 20; the direction closer to the optical axis is called "inner," and the direction relatively farther from the optical axis is called "outer."

[0090] Specifically, the focusing function has certain requirements for both focusing speed and focusing accuracy. A key factor in achieving good focusing performance is the ability to quickly and accurately adjust the lens position to ensure sharp imaging. In this application, the focusing carrier 123, which moves during autofocus, is housed within the image stabilization carrier 121, which moves during optical image stabilization. During autofocus, only the focusing carrier 123 needs to be moved to move the lens assembly 20. This results in a relatively small weight of the components that the focusing drive assembly 1320 needs to drive. Consequently, the focusing drive assembly 1320 can quickly adjust the position of the lens assembly 20, and the lens assembly 20 can respond more quickly to the drive of the focusing drive assembly 1320, thus achieving fast focusing.

[0091] Furthermore, the focusing motion stroke of the lens assembly 20 is relatively large. The focusing drive component 1320 for autofocus only needs to move the focusing carrier 123 to move the lens assembly 20, which helps to achieve a longer motion stroke for the lens assembly 20. Moreover, thanks to the relatively small weight of the components driven by the focusing drive component 1320, the focusing drive component 1320 can more precisely control the movement of the lens assembly 20, which helps to improve focusing accuracy.

[0092] The image stabilization drive assembly 1310 for optical image stabilization can be designed to surround the outer periphery of the image stabilization carrier 121, which allows for more flexible arrangement of the image stabilization drive assembly 1310. Furthermore, since the stabilization travel is shorter than the focusing travel, the image stabilization drive assembly 1310 can more easily control the movement of the lens assembly 20, helping to improve the accuracy of optical image stabilization and reduce over-compensation or under-compensation.

[0093] The image stabilization drive assembly 1310 is mounted on the outside 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 focus drive assembly 1320 is mounted on the outside of the focus carrier 123. Specifically, the focus drive assembly 1320 is mounted between the focus carrier 123 and the image stabilization carrier 121, or between the focus carrier 123 and the base 111.

[0094] In the embodiments of this application, the driving of the image stabilization carrier 121, the frame 122, and the focusing carrier 123 is achieved through the cooperation of magnets and coils. Accordingly, as Figure 2 , Figure 12 and Figure 13 As shown, 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 this application, the first axial direction D1 is defined as the direction in which the first image stabilization coil 132 and the first image stabilization magnet 131 are arranged opposite each other, and the second axial direction D2 is the direction in which the second image stabilization coil 134 and the second image stabilization magnet 133 are arranged opposite each other.

[0095] Accordingly, in one embodiment of this application, as Figure 2 and Figure 13As shown, the first image stabilization coil 132 and the first image stabilization magnet 131 are opposite each other along the first axial direction D1. The first image stabilization coil 132 and the first image stabilization magnet 131 drive the image stabilization carrier 121 to move relative to the base 111 along the first axial direction D1, thereby causing the frame 122, the focusing carrier 123, and the lens assembly 20 to move relative to the base 111 along the first axial direction D1 via the image stabilization carrier 121. Figure 2 and Figure 12 As shown, the second image stabilization coil 134 and the second image stabilization magnet 133 are opposite each other in the second axial direction D2. The second image stabilization coil 134 and the second image stabilization magnet 133, being opposite each other in the second axial direction D2, drive the image stabilization carrier 121 to move relative to the frame 122 and the base 111 along the second axial direction D2, thereby causing the focusing carrier 123 and the lens assembly 20 to move relative to the frame 122 and the base 111 along the second axial direction D2. Figure 2 and Figure 13 As shown, the focusing drive assembly 1320 includes a focusing coil 136 and a focusing magnet 135. In one embodiment of this application, the focusing coil 136 and the focusing magnet 135 are opposite each other in a first axial direction D1, for driving the focusing carrier 123 to move along the optical axis direction D.

[0096] Specifically, the focusing drive assembly 1320 is a moving magnet structure. A moving magnet structure means that under the interaction of a coil and a magnet, the magnet moves relative to the coil, thereby driving a component fixed to the magnet to move. Specifically, the first image stabilization coil 132 and the first image stabilization magnet 131 are disposed on the second side of the image stabilization carrier 121; the second image stabilization coil 134 and the second image stabilization magnet 133 are disposed on the first side of the image stabilization carrier 121. Correspondingly, the first image stabilization coil 132 and the first image stabilization magnet 131 are located on the second side of the motor 10; the second image stabilization coil 134 and the second image stabilization magnet 133 are located on the first side of the motor 10. In one embodiment of this application, the first anti-shake magnet 131 is fixed to the second side of the anti-shake carrier 121, the first anti-shake coil 132 is fixed to the second base sidewall 1113 of the base 111; the second anti-shake magnet 133 is fixed to the first side of the anti-shake carrier 121, and the second anti-shake coil 134 is fixed to the first base sidewall 1112 of the base 111.

[0097] The first stabilizing magnet 131 has only one magnetic pole (N or S pole) facing the first stabilizing coil 132. The second stabilizing magnet 133 has only one magnetic pole (N or S pole) facing the second stabilizing 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 setting direction of the first anti-shake coil 132 and the first anti-shake magnet 131), so that the first anti-shake magnet 131 moves closer to or further away from the first anti-shake coil 132. Correspondingly, since the first anti-shake magnet 131 is fixed to the anti-shake carrier 121 and the first anti-shake coil 132 is fixed to the base 111, the anti-shake carrier 121 moves relative to the base 111 along the relative setting direction of the first anti-shake coil 132 and the first anti-shake magnet 131 under the drive of the first anti-shake magnet 131, and drives the frame 122 to move relative to the base 111 along the relative setting 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 setting direction of the second anti-shake coil 134 and the second anti-shake magnet 133), so that the second anti-shake magnet 133 moves closer to or further away from the second anti-shake coil 134. Correspondingly, since the second anti-shake magnet 133 is fixed to the anti-shake carrier 121 and the second anti-shake coil 134 is fixed to the base 111, the anti-shake carrier 121 moves relative to the frame 122 and the base 111 along the relative setting direction of the second anti-shake coil 134 and the second anti-shake magnet 133 under the drive of the second anti-shake magnet 133.

[0098] It should be understood that in other embodiments of this application, the first image stabilization coil 132 and the first image stabilization magnet 131 may be designed to drive the image stabilization carrier 121 to move relative to the frame 122 and the base 111 along the first axis direction D1, and drive the focusing carrier 123 and the lens assembly 20 to move relative to the base 111 along the first axis direction D1 through the image stabilization carrier 121; the second image stabilization coil 134 and the second image stabilization magnet 133 are designed to drive the image stabilization carrier 121 to move relative to the base 111 along the second axis direction D2, and then 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 image stabilization carrier 121.

[0099] When the first stabilization coil 132 is energized, the stabilization carrier 121 moves relative to the base 111 and the frame 122 along the relative arrangement direction of the first stabilization coil 132 and the first stabilization magnet 131, driven by the first stabilization magnet 131. When the second stabilization coil 134 is energized, the stabilization carrier 121 moves relative to the base 111 along the relative arrangement direction of the second stabilization coil 134 and the second stabilization magnet 133, driven by the second stabilization magnet 133, and drives the frame 122 to move relative to the base 111 along the relative arrangement direction of the first stabilization coil 132 and the first stabilization magnet 131.

[0100] More specifically, the first stabilizing magnet 131 can be designed to be at least partially embedded in the stabilizing carrier 121, and / or the first stabilizing coil 132 can be at least partially embedded in the base 111, to reduce the lateral space occupied by the first stabilizing coil 132 and the first stabilizing magnet 131, thereby reducing the lateral dimension of the motor 10, and thus reducing the lateral dimension of the camera module. The second stabilizing magnet 133 can be designed to be at least partially embedded in the stabilizing carrier 121, and / or the second stabilizing coil 134 can be at least partially embedded in the base 111, to reduce the lateral space occupied by the second stabilizing coil 134 and the second stabilizing magnet 133, thereby reducing the lateral dimension of the motor 10, and thus reducing the lateral dimension of the camera module.

[0101] The focusing coil 136 and the focusing magnet 135 are disposed on the fourth side of the focusing carrier 123. Correspondingly, the focusing coil 136 and the focusing magnet 135 are located on the fourth side of the motor 10. In one embodiment of this 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 image stabilization carrier 121.

[0102] In one modified embodiment of this 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.

[0103] Furthermore, the focusing magnet 135 may be designed to be at least partially embedded in the focusing carrier 123, and / or the focusing coil 136 may be at least partially embedded in the image stabilization carrier 121, in order to reduce the lateral space occupied by the focusing drive assembly 1320, thereby reducing the lateral size of the motor 10.

[0104] As described above, in this application, both the focusing drive assembly 1320 and the image stabilization drive assembly 1310 are moving magnet structures. Accordingly, the focusing magnet 135 is mounted on the focusing carrier 123; the first image stabilization magnet 131 and the second image stabilization magnet 133 are mounted on the image stabilization carrier 121; the focusing coil 136 is mounted on the image stabilization carrier 121 or the base 111; the first image stabilization coil 132 and the second image stabilization coil 134 are mounted on the base 111. This arrangement facilitates subsequent wiring of the focusing coil 136, the first image stabilization coil 132, and the second image stabilization coil 134, enabling electrical conduction of the focusing coil 136, the first image stabilization coil 132, and the second image stabilization coil 134. Specifically, on the one hand, the mounting carrier of the focusing coil 136 (i.e., the image stabilization carrier 121 or the base 111) is similar to or the same as the mounting carrier of the first image stabilization coil 132 and the second image stabilization coil 134 (i.e., the base 111), making the wiring of the focusing coil 136, the first image stabilization coil 132, and the second image stabilization coil 134 more convenient. On the other hand, the image stabilization carrier 121 and the base 111 are closer to the outer side of the motor 10 than the focusing carrier 123, facilitating the outward extension of the conductive structure of the focusing coil 136, the first image stabilization coil 132, and the second image stabilization coil 134.

[0105] In this application, the motor 10 is not provided with a drive component 13 on at least one side, and correspondingly, the camera module is not provided with a drive component 13 on at least one side. In this way, when the camera module is installed on a terminal mobile device, if the terminal mobile device is provided with other camera modules, the side of the camera module of this application that is not provided with a drive component 13 can be adjacent to other camera modules to avoid magnetic interference between multiple camera modules.

[0106] It is worth mentioning that in this application, the magnets and coils of the drive component 13 are arranged relative to each other in the lateral direction. On the one hand, compared with the arrangement of magnets and coils in the optical axis direction D, the height of the motor 10 can be reduced to a certain extent. On the other hand, since two adjacent pairs of magnets-coils are arranged in different lateral directions, for example, the first anti-shake coil 132 and the first anti-shake magnet 131 are arranged in the first axial direction D1, and the second anti-shake coil 134 and the second anti-shake magnet 133 are arranged in the second axial direction D2, compared with all the magnets-coils being arranged in the vertical direction, it can avoid affecting the magnetic field of the other pair of magnets-coils in the other direction when one pair of magnets-coils moves relative to each other in one direction.

[0107] Furthermore, in this application, such as Figure 2As shown, the focusing drive component 1320 and the image stabilization drive component 1310 are respectively arranged on different sides of the motor 10, namely, the fourth side, the second side and the first side. On the one hand, this can avoid mutual interference between the focusing drive component 1320 and the image stabilization drive component 1310 to a certain extent, which helps to ensure their respective driving stability. On the other hand, it increases the space for each magnet to be placed and the overall magnetic field is more evenly distributed, which helps to improve the image stabilization and focusing effect.

[0108] It is also worth mentioning that, in one embodiment of this application, the lower surface of the focusing drive assembly 1320 of the motor 10 for driving the lens assembly 20 to autofocus is at a relatively low height. Specifically, the bottom surface of the focusing magnet 135 of the focusing drive assembly 1320 is lower than the bottom surface of the first image stabilizing magnet 131 and / or the bottom surface of the second image stabilizing magnet 133 of the image stabilizing drive assembly 1310; the bottom surface of the focusing coil 136 of the focusing drive assembly 1320 is lower than the bottom surface of the first image stabilizing coil 132 and / or the second image stabilizing coil 134 of the image stabilizing drive assembly 1310. This not only helps to reduce the height of the motor 10, thereby reducing the height of the camera module, but also increases the focusing motion travel, thereby improving the focusing function of the camera module.

[0109] It should be understood that the larger the dimensions of the focusing magnet 135 and the focusing coil 136 in the height direction of the motor 10, the greater the driving force and the longer the driving stroke that the focusing drive assembly 1320 can provide. However, increasing the dimensions of the focusing magnet 135 and the focusing coil 136 in the height direction of the motor 10 may lead to an increase in the height of the motor 10. In this application, the dimensions of the focusing magnet 135 and the focusing coil 136 in the height direction of the motor 10 are increased by extending them downwards, thereby increasing the focusing motion stroke and improving the focusing function of the camera module. Furthermore, it is possible to avoid increasing the height of the motor 10. Moving the focusing magnet 135 and the focusing coil 136 downwards as a whole can also reduce the height of the motor 10.

[0110] In the embodiments of this application, such as Figure 2As shown, the support assembly 14 includes three support portions, namely 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 image stabilization carrier 121; the third support portion 143 is configured to support and guide the focusing carrier 123. The first support portion 141 is disposed on the upper side of the frame 122, located between the frame 122 and the image stabilization carrier 121; the second support portion 142 is disposed on the lower side of the frame 122, located between the image stabilization carrier 121 and the base 111.

[0111] like Figure 2 , Figure 10 and Figure 11 As shown, the first support portion 141 includes three balls 1410, which are disposed between the frame 122 and the anti-shake carrier 121, so that the anti-shake carrier 121 can move relative to the frame 122 with a small frictional force; the second support portion 142 includes another three balls 1410, which are disposed between the frame 122 and the base 111, so that the frame 122 can move relative to the base 111 with a small frictional force.

[0112] In one example of this application, such as Figure 2 , Figure 5 and Figure 6 As shown, the frame 122 is L-shaped, including a first side 1221 and a second side 1222. The second side 1222 is angled relative to the first side 1221. Accordingly, the frame 122 has a corner 1223 located between the first side 1221 and the second side 1222. The corner 1223 is located between the first side and the second side of the motor 10; the first side 1221 extends along the second axial direction D2 between the first side and the third side of the motor 10, and the end of the first side 1221 is close to the third side of the motor 10; the second side 1222 extends along the first axial direction D1 between the second side and the fourth side of the motor 10, 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 axial direction D2; the length direction of the second side 1222 is consistent with the first axial direction D1.

[0113] The three ball bearings 1410 of the first support portion 141 are respectively disposed on the upper side of the end of the first side 1221, the upper side of the corner 1223, and the upper side of the end of the second side 1222 of the L-shaped frame 122. The three ball bearings 1410 of the second support portion 142 are respectively disposed on the lower side of the end of the first side 1221, the lower side of the corner 1223, and the lower side of the end of the second side 1222 of the L-shaped frame 122.

[0114] Specifically, the frame 122 has three ball grooves on the side facing the anti-shake carrier 121 (i.e., the upper side of the frame 122) and the side facing the base 111 (i.e., the lower side of the frame 122). The three ball grooves on the side of the frame 122 facing the anti-shake carrier 121 are frame top surface ball grooves 1224, which are respectively located on the upper side of the end of the first side 1221, the upper side of the corner 1223, and the upper side of the end of the second side 1222. The three ball grooves on the side of the frame 122 facing the base 111 are frame bottom surface ball grooves 1225, which are respectively located on the lower side of the end of the first side 1221, the lower side of the corner 1223, and the lower side of the end of the second side 1222.

[0115] On the side of the base 111 facing the frame 122 (i.e., the upper side of the base 111), three ball grooves are also provided at corresponding positions (i.e., positions opposite to the three frame bottom ball grooves 1225 in the optical axis direction D), which are called base ball grooves 1115; the dimensions of the three base ball grooves 1115 are respectively larger than the dimensions of the three frame bottom ball grooves 1225 at the corresponding positions, such as... Figure 10 As shown. More specifically, the dimension of the base ball groove 1115 in its length direction is larger than the dimension of the corresponding frame bottom ball groove 1225.

[0116] In particular, in one embodiment of this application, such as Figure 7 and Figure 10As shown, the base ball groove 1115 extends along the first axial direction D1, meaning the length direction of the base ball groove 1115 is the first axial direction D1. The dimension of the base ball groove 1115 in the first axial direction D1 is larger than the dimension of the frame bottom ball groove 1225. This has the advantage of allowing the portion of the frame 122 where the ball 1410 is located to be designed to be smaller, thereby reducing the overall size of the frame 122. Furthermore, the dimension of the frame bottom ball groove 1225 also extends along the first axial direction D1. That is, both the frame bottom ball groove 1225 and the base ball groove 1115 are elongated ball grooves extending along the first axial direction D1, but the dimension of the frame bottom ball groove 1225 in the first axial direction D1 is shorter. This helps to keep the ball 1410 rolling, reducing the risk of the ball 1410 becoming stuck and subject to sliding friction.

[0117] Furthermore, the two frame bottom ball grooves 1225 provided on the frame 122 along the first axis direction D1 are guide grooves with lateral guiding function, with a V-shaped or approximately V-shaped cross section, and the width gradually decreases from top to bottom in the depth direction, used to restrict the rolling direction of the ball 1410; the other frame bottom ball groove 1225 is a support groove without lateral guiding function, with a U-shaped cross section, and the width is consistent in the depth direction, not restricting the rolling direction of the ball 1410; similarly, the two base ball grooves 1115 provided on the base 111 along the first axis direction D1 are guide grooves with lateral guiding function, with a V-shaped or approximately V-shaped cross section, and the width gradually decreases from top to bottom in the depth direction, used to restrict the rolling direction of the ball 1410; the other base ball groove 1115 is a support groove without lateral guiding function, with a U-shaped cross section, and the width is consistent in the depth direction, not restricting the rolling direction of the ball 1410.

[0118] Correspondingly, the anti-shake carrier 121 also has three ball grooves at corresponding positions on the side facing the frame 122 (i.e., positions opposite to the three frame top surface ball grooves 1224 in the optical axis direction D), which are three carrier ball grooves 1211; the dimensions of the three carrier ball grooves 1211 are respectively larger than the dimensions of the three frame top surface ball grooves 1224. More specifically, the dimension of the carrier ball groove 1211 in its length direction is larger than the dimension of the corresponding frame top surface ball groove 1224.

[0119] In particular, such as Figure 8As shown, the carrier ball groove 1211 extends along the second axial direction D2, that is, the length direction of the carrier ball groove 1211 is the second axial direction D2. The dimension of the carrier ball groove 1211 in the second axial direction D2 is larger than that of the frame top surface ball groove 1224. The advantage of this is that the portion of the frame 122 where the ball 1410 is located can be designed to be smaller, thereby reducing the size of the frame 122. Furthermore, the frame top surface ball groove 1224 also extends along the second axial direction D2, that is, both the frame top surface ball groove 1224 and the carrier ball groove 1211 are elongated ball grooves extending along the second axial direction D2, but the dimension of the frame top surface ball groove 1224 in the second axial direction D2 is shorter. This is beneficial for keeping the ball 1410 rolling, thereby reducing the risk of the ball 1410 getting stuck and becoming subject to sliding friction.

[0120] Furthermore, the two frame top surface ball grooves 1224 provided on the frame 122 along the second axis direction D2 are guide grooves with lateral guiding function, with a V-shaped or approximately V-shaped cross section, and the width 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, with a U-shaped cross section, and the width is consistent 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 second axis direction D2 are guide grooves with lateral guiding function, with a V-shaped or approximately V-shaped cross section, and the width 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, with a U-shaped cross section, and the width is consistent in the depth direction, and does not restrict the rolling direction of the ball 1410.

[0121] Furthermore, 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. Even further, if the frame top surface ball groove 1224 and frame bottom surface ball groove 1225 on the frame 122 have a length direction, they are also vertically arranged.

[0122] It should be understood that in other embodiments of this application, the base ball groove 1115 can be designed to extend along the second axis direction D2, that is, 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 larger than that of the frame bottom ball groove 1225. The advantage of this is that the portion of the frame 122 where the ball 1410 is located can be designed to be smaller, thereby reducing the size of the frame 122. Furthermore, the frame bottom ball groove 1225 also extends along the second axis direction D2, that is, both the frame bottom ball groove 1225 and the base ball groove 1115 are elongated 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. This helps to keep the ball 1410 rolling, reducing the risk of the ball 1410 becoming stuck and subject to sliding friction.

[0123] Furthermore, in other embodiments of this application, the two frame bottom ball grooves 1225 provided on the frame 122 along the second axis direction D2 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 bottom ball groove 1225 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 base ball grooves 1115 provided on the base 111 along the second axis direction D2 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 base ball groove 1115 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.

[0124] In other embodiments of this application, the carrier ball groove 1211 can be designed to extend along the first axial direction D1, that is, the length direction of the carrier ball groove 1211 is the first axial direction D1, and the size of the carrier ball groove 1211 in the first axial direction D1 is larger than that of the frame top surface ball groove 1224. The advantage of this is that the portion of the frame 122 where the ball 1410 is located can be designed to be smaller, thereby reducing the size of the frame 122. Furthermore, the frame top surface ball groove 1224 also extends along the first axial direction D1, that is, both the frame top surface ball groove 1224 and the carrier ball groove 1211 are elongated ball grooves extending along the first axial direction D1, but the frame top surface ball groove 1224 is shorter in the first axial direction D1. This helps to keep the ball 1410 rolling, reducing the risk of the ball 1410 getting stuck and causing sliding friction.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] It is also worth mentioning that in an embodiment where the frame 122 is not provided in the active component 12, the ball bearing 1410 and the cross ball bearing groove can be provided between the anti-shake carrier 121 and the base 111, so that support and guidance in two directions can be achieved through a single layer of the ball bearing 1410.

[0129] In an embodiment of the present application, the third support portion 143 is disposed on the side where the focusing drive assembly 1320 is located. In this way, the acting point of the force generated by the focusing drive assembly 1320 is closer to the third support portion 143, thereby reducing the tilting moment generated during focusing. The moment for the focusing carrier 123 to tilt or shift is smaller, making it difficult for the focusing carrier 123 to tilt during the focusing process, and thus ensuring the clarity of the image and the accuracy of focusing. Moreover, since the tilt of the focusing carrier 123 is reduced, the focusing drive assembly 1320 can respond to the focusing instruction faster and achieve fast and accurate focusing. Correspondingly, in an embodiment of the present application, the focusing drive assembly 1320 and the third support portion 143 are disposed on the fourth side of the focusing carrier 123.

[0130] In an embodiment of the present application, as Figures 2 to 4 shown, the third support portion 143 includes two guide rods, where the two guide rods are the first guide rod 1420 and the 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 focusing carrier 123 and are respectively disposed on both sides of the focusing magnet 135. The length extension directions of the first guide rod 1420 and the second guide rod 1430 are consistent with the optical axis direction D. The lengths of the first guide rod 1420 and the second guide rod 1430 are greater than the height of the focusing carrier 123, and even greater than the movement stroke of the focusing carrier 123 along the optical axis direction D, so that the focusing carrier 123 can be supported within the movement stroke.

[0131] 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 Figure 10 shown, the anti-shake carrier 121 includes a carrier insert 1212 embedded therein, and at least a part of the carrier insert 1212 horizontally extends out of the anti-shake carrier 121 from the bottom side 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.

[0132] More specifically, at least a part of the carrier insert 1212 is a vertical part, which is 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 part of the carrier insert 1212 is in a "mouth" shape, as Figure 9As shown. The "mouth" - shaped structure of the vertical part of the carrier insert 1212 makes the middle hollow, which can be used to accommodate components such as the focusing coil 136 and the focusing sensing element 163. It should be understood that the side wall of the anti - shake carrier 121 for installing the focusing coil 136 may be provided with through - holes so that the focusing coil 136 is accommodated in the through - holes of this side wall of the anti - shake carrier 121.

[0133] 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 by other means. For example, they can be fixed to the anti - shake carrier 121 by other means, or fixed to other parts of the anti - shake carrier 121, or fixed to the focusing carrier 123.

[0134] 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, during the injection molding process of the anti - shake carrier 121, the first guide rod 1420 and the second guide rod 1430 are embedded into 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 can reduce the height of the first guide rod 1420 and the second guide rod 1430, and further reduce the height of the motor 10. Further, the carrier insert 1212 can be removed to further reduce the height of the motor 10.

[0135] 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 are integrally injection - molded with the anti - shake carrier 121 by insert injection molding process. Of course, a connecting structure can also 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 are integrally injection - molded with the anti - shake carrier 121 by insert injection molding process to improve the parallelism between the first guide rod 1420 and the second guide rod 1430.

[0136] Two guide rod grooves are provided between the focusing carrier 123 and the image stabilizing carrier 121. The two guide rod grooves are 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 selectively fitted tightly with the first guide rod groove 1231 and the second guide rod groove 1232, i.e., a tight fit, or it can be loosely fitted with the first guide rod groove 1231 and the second guide rod groove 1232, i.e., a certain degree of mobility.

[0137] In particular, such as Figure 10 As shown, the first guide rod groove 1231 is located on the side of the motor 10 without the L-shaped frame. Correspondingly, the first guide rod groove 1231 is located at a position on the motor 10 where the ball bearing 1410 is not installed, for example, at the corner between the third and fourth sides of the motor 10, and is a guide groove with lateral guiding function, the width of which gradually decreases from the inside to the outside in the depth direction; the second guide rod groove 1232 has a basically consistent width from the inside to the outside in the depth direction and does not have lateral guiding function.

[0138] It is worth mentioning that the L-shaped frame 122 and the ball bearing 1410 are configured with a V-shaped first guide groove 1231, providing installation space. Specifically, compared to a quadrilateral frame, the L-shaped frame 122 has an open corner, which provides installation space for the V-shaped first guide groove 1231, which requires a larger installation space. Correspondingly, in order not to increase the lateral dimension of the motor 10, the second guide groove 1232, which is opposite to the first guide groove 1231 in the second axial direction D2, can be a guide groove without lateral guiding function. Accordingly, the two guide grooves are arranged such that one of them is a V-shaped guide groove with guiding function, and the other is a guide groove without lateral guiding function. Furthermore, in order to reduce the space occupied by the guide groove, the second guide groove 1232 on the side closer to the ball bearing 1410 is set as a semi-open groove with a flat bottom surface, making its size smaller.

[0139] It is worth mentioning that the contact points, number, and area between the first guide rod 1420 and the second guide rod 1430 and the guide rod groove affect the wear degree of the focusing carrier 123. This application reduces the wear of the focusing carrier 123 due to long-term movement by designing the contact points and number of the first guide rod 1420 and the second guide rod 1430 with the guide rod groove, thereby improving the durability and reliability of the focusing carrier 123, and consequently improving the durability and reliability of the motor 10.

[0140] In one embodiment of this application, such as Figure 2As shown, the focusing carrier 123 has at least three contact positions formed on its sidewall, namely a first contact position 102, a second contact position 103, and a third contact position 104. In the relative 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 side of the focusing drive assembly 1320 opposite 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 than 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.

[0141] In one embodiment of this application, the first guide rod 1420 abuts against the first contact position 102 and the second contact position 103, and the second guide rod 1430 abuts against the third contact position 104.

[0142] Accordingly, in one embodiment of this application, the number of contact points between the focusing carrier 123 and the first guide rod 1420 is at least two, namely the first contact point 102 and the second contact point 103. The number of contact points between the focusing carrier 123 and the second guide rod 1430 is at least one, namely the third contact point 104.

[0143] Specifically, the focusing carrier 123 has contact protrusions 1233 at two opposite ends in the height direction of the first guide rod groove 1231; the first guide rod 1420 contacts the contact protrusions 1233 at the two opposite ends in the height direction of the first guide rod groove 1231; the contact protrusions 1233 at the two opposite ends in the height direction of the first guide rod groove 1231 form the first contact position 102 and the second contact position 103. The focusing carrier 123 has a contact protrusion 1233 in the middle of the height direction of the second guide rod groove 1232, the second guide rod 1430 contacts the contact protrusion 1233 in the middle of the height direction of the second guide rod groove 1232, and the contact protrusion 1233 in the middle of the height direction of the second guide rod groove 1232 forms the third contact position 104.

[0144] Correspondingly, along the optical axis direction D, the height of the third contact position 104 is higher than the height of the second contact position 103 and lower than the height of the first contact position 102; the first contact position 102, the second contact position 103, and the third contact position 104 form a triangular positional 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 image stabilization carrier 121, reducing the risk of the focusing carrier 123 tipping over.

[0145] Since the second guide rod 1430 only needs to abut against one contact point, its length can be shorter than that of the first guide rod 1420. This helps maintain the parallelism of the second guide rod 1430 and provides more space for the installation of other components.

[0146] It is worth mentioning that the third support portion 143 can also be implemented in other ways to achieve triangular support. The third support portion 143 can be implemented as a combination of a guide rod and a slider, or a combination of a guide rod and a ball bearing 1410, or a combination of a slider and a ball bearing 1410. The component in the third support portion 143 that abuts against the first contact position 102 can be a guide rod, a slider, or a ball bearing 1410; the component that abuts against the second contact position 103 can be a guide rod, a slider, or a ball bearing 1410; and the component that abuts against the third contact position 104 can be a guide rod, a slider, or a ball bearing 1410.

[0147] like Figure 2 As shown, the magnetic attachment assembly 15 includes an image stabilization magnetic attachment piece 151 and a focusing magnetic attachment piece 152. The image stabilization magnetic attachment piece 151 is used to attract the image stabilization carrier 121; the focusing magnetic attachment piece 152 is used to attract the focusing carrier 123. Specifically, the image stabilization magnetic attachment piece 151 is used to attract the image stabilization carrier 121 to the frame 122 and the base 111; the focusing magnetic attachment piece 152 is used to attract the focusing carrier 123 to the image stabilization frame 122.

[0148] The focusing magnetic chuck 152 is located on the side of the focusing coil 136 opposite to the focusing magnet 135. The focusing magnetic chuck 152 is magnetically conductive and can attract the focusing magnet 135. The magnetic attraction between the focusing magnetic chuck 152 and the focusing magnet 135 brings the focusing carrier 123 and the image stabilization carrier 121 closer together. The focusing carrier 123 is tightly supported by the third support portion 143, which improves driving stability and prevents the focusing carrier 123 and the image stabilization carrier 121 from falling off. In other words, the magnetic attraction between the focusing magnetic chuck 152 and the focusing magnet 135 causes the focusing carrier 123 to be adsorbed onto the side wall of the image stabilization carrier 121.

[0149] It is worth mentioning that, in this application, it is desirable that the resultant force of the magnetic attraction between the focusing carrier 123 and the image stabilizing carrier 121 is biased towards the side where the first contact position 102 and the second contact position 103 are located. More specifically, it is desirable that the resultant force of the magnetic attraction between the focusing carrier 123 and the image stabilizing carrier 121 is biased towards the side where the first contact position 102 and the second contact position 103 in the length direction of the focusing magnet 135 relative to the side where the third contact position 104 is located, so that the focusing carrier... 123 is less likely to tip over relative to the image stabilization carrier 121, that is, it is less likely to deflect relative to the image stabilization carrier 121 with the first contact position 102 and the second contact position 103 as the axis of rotation. For this reason, this application has made a specific design to the focusing magnetic accumulator 152 that affects the magnetic field of the focusing carrier 123. For example, the overlapping area of ​​the focusing magnetic accumulator 152 with the focusing magnet 135 in the relative arrangement direction of the focusing magnet 135 and the focusing coil 136 is biased towards the first contact position 102. 2 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 accumulator 152 and the focusing magnet 135 is biased towards the side where the first contact position 102 and the second contact position 103 are located, thereby causing the resultant force of the magnetic attraction between the focusing carrier 123 and the image stabilization carrier 121 to be biased towards the side where the first contact position 102 and the second contact position 103 are located, and at the same time, biased towards the first guide rod 1420 and the groove with lateral guide The first guide rod groove 1231, which has a V-shaped function, improves the stability of the focusing carrier 123 supported on the side wall of the image stabilization carrier 121, making the focusing carrier 123 less likely to tip over relative to the image stabilization carrier 121. That is, it is less likely to deflect relative to the image stabilization carrier 121 with the first contact position 102 and the third contact position 104 as the axis of rotation, or with the second contact position 103 and the third contact position 104 as the axis of rotation, thereby reducing the risk of the focusing carrier 123 tipping over.

[0150] In one embodiment of this application, the positional relationship between the focusing magnetic accumulator 152 and the focusing magnet 135 is further manifested as follows: the focusing magnetic accumulator 152 is eccentrically positioned relative to the focusing magnet 135, that is, the center of the focusing magnetic accumulator 152 is not aligned with the center of the focusing magnet 135. Specifically, the center of the focusing magnetic accumulator 152 is offset relative to the center of the focusing magnet 135 towards the first contact position 102 and the second contact position 103 in the relative arrangement direction of the first guide rod 1420 and the second guide rod 1430. Further, this is manifested as follows: the distance between the center of the focusing magnetic accumulator 152 and the first contact position 102 in the relative setting direction of the first guide rod 1420 and the second guide rod 1430 is less than the distance between the center of the focusing magnetic accumulator 152 and the third contact position 104 in the relative setting direction of the first guide rod 1420 and the second guide rod 1430; the distance between the focusing magnetic accumulator 152 and the second contact position 103 in the relative setting direction of the first guide rod 1420 and the second guide rod 1430 is less than the distance between the focusing magnetic accumulator 152 and the third contact position 104 in the relative setting direction of the first guide rod 1420 and the second guide rod 1430; or further, this is manifested as follows: the distance between the center of the focusing magnetic accumulator 152 and the first contact position 102 in the relative setting direction 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 in the relative setting direction of the first guide rod 1420 and the second guide rod 1430. The distance between the center of the focusing magnetic accumulator 152 and the second contact position 103 in the relative setting direction 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 relative setting direction of the first guide rod 1420 and the second guide rod 1430; the distance between the center of the focusing magnetic accumulator 152 and the third contact position 104 in the relative setting direction 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 relative setting direction of the first guide rod 1420 and the second guide rod 1430.

[0151] 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.

[0152] 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.

[0153] It is worth mentioning that the first anti-shake magnet 131 moves relative to the first anti-shake coil 132 in a relatively set direction. Assuming that after the first anti-shake magnet 131 moves, it extends all or part of its movement direction relative to the first anti-shake coil 132 beyond the first magnetic attractor 1511, the first anti-shake magnet 131 and the first magnetic attractor 1511 will generate a magnetic attraction force (component force) along the movement direction. This magnetic attraction force will cause the first anti-shake magnet 131 to move closer to the first magnetic attractor 1511 along the movement direction, thus becoming a resistance to the movement of the anti-shake carrier 121 relative to the base 111. Therefore, in this application, in order to reduce the influence of the resistance generated between the first anti-shake magnet 131 and the first magnetic attractor 1511 along the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132 after the first anti-shake magnet 131 moves, the size of the first magnetic attractor 1511 in the movement direction of the first anti-shake magnet 131 relative to the first anti-shake coil 132 is designed to be larger than the size of the first anti-shake magnet 131 in the movement direction of the first anti-shake coil 132.

[0154] Preferably, the dimension of the first magnetic chuck 1511 in the direction of movement 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 dimension of the first anti-shake magnet 131 in the direction of movement of the first anti-shake coil 132 and the travel distance of the first anti-shake magnet 131 in the direction of movement of the first anti-shake coil 132. This ensures that the first anti-shake magnet 131 never exceeds the first magnetic chuck 1511 in the direction of movement of the first anti-shake coil 132 during its driving process. Specifically, the orthographic projection of the first anti-shake magnet 131 on the optical axis direction D does not exceed the first magnetic chuck 1511 in the direction of movement of the first anti-shake magnet 131 relative to the first anti-shake coil 132.

[0155] In one embodiment of this application, the first anti-shake magnet 131 moves along the first axial direction D1, that is, the direction of movement of the first anti-shake magnet 131 relative to the first anti-shake coil 132 is the first axial direction D1. Correspondingly, the dimension of the first magnetic member 1511 in the first axial direction D1 is larger than the dimension of the first anti-shake magnet 131 in the first axial direction D1, such 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.

[0156] 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. 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.

[0157] In one embodiment of this application, the second anti-shake magnet 133 moves along the second axial direction D2, that is, the direction of movement of the second anti-shake magnet 133 relative to the second anti-shake coil 134 is the second axial direction D2. Correspondingly, the dimension of the second magnetic member 1512 in the second axial direction D2 is larger than the dimension of the second anti-shake magnet 133 in the second axial direction D2, such as... Figure 7 As shown. Preferably, the dimension of the second magnetic member 1512 in the second axial direction D2 is greater than or equal to the sum of the dimension of the second anti-shake magnet 133 in the second axial direction D2 and the travel distance of the second anti-shake magnet 133 in the second axial direction D2. Thus, during the movement of the second anti-shake magnet 133 relative to the second anti-shake coil 134 in the second axial direction D2, the second anti-shake magnet 133 never exceeds the second magnetic member 1512 in the second axial direction D2. This is manifested in that the orthographic projection of the second anti-shake magnet 133 in the optical axis direction D does not exceed the second magnetic member 1512 in the second axial direction D2.

[0158] It is also worth mentioning that the first magnetic member 1511 and the second magnetic member 1512 are respectively disposed on one side near the middle ball bearing 1410, that is, near the side of the ball bearing 1410 disposed at the corner 1223 of the frame 122. For example, the first magnetic member 1511 is disposed on the second side of the base 111 near the side of the ball bearing 1410 disposed at the corner 1223 of the frame 122; the second magnetic member 1512 is disposed on the first side of the base 111 near the side of the ball bearing 1410 disposed at the corner 1223 of the frame 122. On the one hand, this arrangement helps to ensure that the overall magnetic attraction force applied to the anti-shake carrier 121 is located near the ball bearing 1410 located 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 the anti-shake carrier 121 tipping over. This arrangement also provides space for setting the sensing component 16 below the first anti-shake magnet 131 and the second anti-shake magnet 133. For example, a component of the sensing component 16 can be set on the side of the first side of the base 111 away from the ball bearing 1410 located at the corner 1223 of the frame 122, and a component of the sensing component 16 can be set on the side of the second side of the base 111 away from the ball bearing 1410 located at the corner 1223 of the frame 122.

[0159] In one embodiment of this application, such as Figure 7As shown, the image stabilization magnetic clasp 151 further includes a magnetic connector 1513, which connects the first magnetic clasp 1511 and the second magnetic clasp 1512, allowing the first magnetic clasp 1511 and the second magnetic clasp 1512 to be installed together, thus simplifying installation. It should be understood that in other embodiments of this application, the image stabilization magnetic clasp 151 may not include the magnetic connector 1513.

[0160] like Figure 9 As shown, the sensing component 16 includes a focus sensing element 163, a first image stabilization sensing element 161, and a second image stabilization sensing element 162. The focus sensing element 163 is used to acquire position change information of the focus carrier 123 relative to the image stabilization carrier 121; the first image stabilization sensing element 161 and the second image stabilization sensing element 162 are used to acquire position change information of the image stabilization carrier 121 relative to the base 111.

[0161] In one embodiment of this application, the focusing sensing element 163 is opposite to the focusing magnet 135. By acquiring the magnetic field change information of the focusing magnet 135, the position change information of the focusing magnet 135 is acquired, thereby acquiring the position change information of the focusing carrier 123 fixed to the focusing magnet 135. The main acquisition information is the position change information of the focusing carrier 123 relative to the image stabilization carrier 121 along the optical axis direction D.

[0162] Furthermore, the focus sensing element 163 is fixed to the image stabilization carrier 121 and may be disposed in the focus coil 136, for example, in the middle of the focus coil 136.

[0163] The first anti-shake sensing element 161 is disposed opposite to the bottom surface of the first anti-shake magnet 131. By acquiring the magnetic field change information of the first anti-shake magnet 131, the position change information of the first anti-shake magnet 131 is acquired, thereby acquiring the position change information of the anti-shake carrier 121 fixed to the first anti-shake magnet 131. The main acquisition information is the position change information of the anti-shake carrier 121 relative to the base 111 along the first axis direction D1.

[0164] Furthermore, the first anti-shake sensing element 161 is located below the first anti-shake magnet 131 and fixed to the base 111. It can be disposed on the side of the first magnetic suction member 1511 away from the ball 1410 disposed at the corner 1223 of the frame 122.

[0165] The second anti-shake sensing element 162 is disposed opposite to the bottom surface of the second anti-shake magnet 133. By acquiring the magnetic field change information of the second anti-shake magnet 133, the position change information of the second anti-shake magnet 133 is acquired, thereby acquiring the position change information of the anti-shake carrier 121 fixed to the second anti-shake magnet 133. The main acquisition information is the position change information of the anti-shake carrier 121 relative to the base 111 along the second axis direction D2.

[0166] Furthermore, the second anti-shake sensing element 162 is located below the second anti-shake magnet 133 and is fixed to the base 111. It can be set on the side of the second magnetic member 1512 away from the ball 1410 set at the corner 1223 of the frame 122.

[0167] The focus sensing element 163, the first image stabilization sensing element 161, and the second image stabilization sensing element 162 may be a Hall sensor, an inductive encoder chip (i.e., an IC chip), or an inductive encoder chip combined with a capacitor, or a TMR.

[0168] like Figure 9 As shown, the conductive component 17 includes an image stabilization circuit board 171, a focusing circuit board 172, and a base conductive insert 173. The base conductive insert 173 is embedded within 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 and the lead-out conductive insert group 1732 are spaced apart along the optical axis direction D, with the coil conductive insert group 1731 located above the lead-out conductive insert group 1732.

[0169] The conductive insert assembly 1732 is embedded in the base body 1111, with one end electrically connected to the image stabilization circuit board 171 and the other end located on one side of the motor 10. It extends outward from the base 111 to form a pin group, which is used for electrical connection with other components of the camera module, such as the photosensitive component 30. In one embodiment of this application, the pin group is located on the first side of the motor 10.

[0170] The coil conductive insert assembly 1731 is embedded in the side wall of the base 111, with both ends 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 electrically connecting the conductive insert assembly 1732 through the anti-shake circuit board 171.

[0171] The image stabilization circuit board 171 is fixed to the base 111 and electrically connected to the image stabilization drive assembly 1310. The first image stabilization sensing element 161, the second image stabilization sensing element 162, and the image stabilization magnetic plate 151 are all fixed to the base 111 by fixing to the image stabilization circuit board 171. The first image stabilization sensing element 161 and the second image stabilization sensing element 162 are also electrically connected to the image stabilization 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 image stabilization circuit board 171 and the conductive insert 173 of the base.

[0172] The focusing circuit board 172 is electrically connected to the focusing drive assembly 1320. Specifically, one end of the focusing circuit board 172 is fixed to the image stabilization carrier 121 and 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 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.

[0173] It is worth mentioning that, since the image stabilization carrier 121 will move relative to the base 111 in the direction perpendicular to the optical axis D, the middle part of the focusing circuit board 172 used to connect the two ends needs to be deformable, so as to reduce the resistance to the movement of the image stabilization carrier 121 relative to the base 111.

[0174] Accordingly, in one embodiment of this application, the focusing circuit board 172 includes a conductive fixing part 1721, a conductive movable part 1722, and a conductive connecting part 1723. The conductive connecting part 1723 is connected between the conductive fixing part 1721 and the conductive movable part 1722.

[0175] The conductive movable part 1722 is one end of the focusing circuit board 172, fixed to the outer surface of the side wall of the image stabilization carrier 121, located on the fourth side of the motor 10, and electrically connected to the focusing coil 136 and the focusing sensing element 163. The focusing magnetic chuck 152 and the focusing coil 136 are respectively disposed 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 image stabilization carrier 121 by fixing to the conductive movable part 1722; the focusing magnetic chuck 152 is fixed to the other side (outer side) of the conductive movable part 1722, so that the focusing magnetic chuck 152 is fixed to the image stabilization carrier 121 by fixing to the conductive movable part 1722.

[0176] The conductive fixing part 1721 is the other end of the focusing circuit board 172, and is fixed to the third base side wall 1114 of the base 111, located on the third side of the motor 10, and connected to the base conductive insert 173, thereby electrically connecting to other components of the camera module, such as the photosensitive component 30, through the base conductive insert 173.

[0177] The conductive movable part 1722 and the conductive fixed part 1721 extend vertically, and the conductive connecting part 1723 is bent horizontally relative 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 bent and connected to the conductive movable part 1722 on the fourth side of the motor 10, and the conductive connecting part 1723 extends from the fourth side of the motor 10 to the first side, then to the second side, and then to the third side. The other end of the conductive connecting part 1723 is bent and connected to the conductive fixed part 1721 on the third side of the motor 10.

[0178] Accordingly, in one embodiment of this application, at least a portion of the focusing circuit board 172 (i.e., the conductive connection portion 1723) extends horizontally above the base 111.

[0179] The conductive movable part 1722 is adjacent to the conductive fixed part 1721 and is located on the fourth and third sides of the motor 10, respectively. The conductive connecting part 1723 extends meanderingly on a portion of the fourth side, the first side, the second side, and the third side of the top of the motor 10, thereby increasing the length of the conductive connecting part 1723 and reducing the impact of the focusing circuit board 172 on the optical image stabilization function.

[0180] In one modified embodiment of this application, such as Figures 15 to 17 As shown, the focusing circuit board 172 includes only a conductive movable part 1722 and a conductive connection part 1723, and does not have a conductive fixing part 1721 located on the third base sidewall 1114 of the base 111. The focusing circuit board 172 extends at least partially above the carrier assembly 110 in a horizontal direction. In this application, the portion of the focusing circuit board 172 extending horizontally above the carrier assembly 110 is defined as the conductive connection part 1723.

[0181] In this modified 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 sequentially along the fourth side, first side, second side, and third side of the motor. The focusing drive assembly 1320 is disposed on the fourth side of the motor. The image stabilization drive assembly 1310 is not disposed on the third side of the motor. Accordingly, the conductive connection portion 1723 extends circumferentially along the motor from the side where the focusing drive assembly 1320 is disposed to the side where the image stabilization drive assembly 1310 is not disposed; more specifically, the conductive connection portion 1723 extends circumferentially along the motor from the side where the focusing coil 136 is disposed to the side where the image stabilization coil and image stabilization magnet are not disposed.

[0182] The conductive connection portion 1723 includes a first end portion 1710, a second end portion 1720, and an intermediate extension portion 1730 located 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 side wall of the image stabilization carrier 121, located on 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 side wall 1114 of the base 111, located on the third side of the motor 10, and connected to the base conductive insert 173, thereby electrically connecting to other components of the camera module, such as the photosensitive assembly 30, through the base conductive insert 173. At least a portion of the base conductive insert 173 extends from the base body 1111 to the third base side wall 1114, and further extends to the second end portion 1720 of the conductive connection portion 1723. Furthermore, at least a portion of the portion where the base conductive insert 173 connects to the second end 1720 of the conductive connection portion 1723 extends horizontally. This increases the contact area with the conductive connection portion 1723 and ensures that a sufficient area is exposed outside the base 111 to form an electrical connection end.

[0183] The conductive movable part 1722 forms the other end of the focusing circuit board 172, extends vertically, is fixed to the outer surface of the side wall of the image stabilization carrier 121, and is located on 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 chuck 152 and the focusing coil 136 are respectively disposed 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 image stabilization carrier 121 by fixing to the conductive movable part 1722; the focusing magnetic chuck 152 is fixed to the other side (outer side) of the conductive movable part 1722, so that the focusing magnetic chuck 152 is fixed to the image stabilization carrier 121 by fixing to the conductive movable part 1722.

[0184] It is worth mentioning that if the conductive movable part 1722 and the conductive connecting part 1723 are formed by bending a single piece of circuit board, due to the influence of bending springback, the conductive connecting part 1723 and the conductive movable part 1722 tend to move away from each other, manifested as: the conductive connecting part 1723 tending to warp upwards, and the conductive movable part 1722 tending to warp outwards. Based on this, in this modified embodiment, the first end 1710 of the conductive movable part 1722 and the conductive connecting part 1723 are not integrally formed, but are connected together by welding, bonding, or other methods. This can, to a certain extent, prevent the first end 1710 of the conductive connecting part 1723 from warping upwards due to bending springback, and the conductive movable part 1722 from warping outwards due to bending springback. Specifically, the bottom surface of the first end 1710 of the conductive connecting part 1723 and the top surface of the conductive movable part 1722 are connected together by welding, bonding, or other methods. In one example of this application, the first end portion 1710 of the conductive connection portion 1723 is fixed to the top surface of the sidewall on the fourth side of the anti-shake carrier 121 and extends beyond the anti-shake carrier 121 in the horizontal direction, so that the first end portion 1710 of the conductive connection portion 1723 has sufficient area to fully contact and connect with the conductive movable portion 1722.

[0185] It should be understood that in other embodiments of this application, the conductive active part 1722 and the conductive connection part 1723 may be designed to be integrally formed by bending a single piece of circuit board.

[0186] At least a portion of the conductive connection 1723 corresponds to the beveled portion of the motor 10, forming a beveled corner transition portion 1724, which creates an obtuse angle transition to avoid the transition angle being too small. This helps to reduce the resistance when the image stabilization carrier 121 moves relative to the base 111. At the same time, it can reduce the risk of the conductive connection 1723 cracking at the transition point, thereby reducing the risk of the focusing circuit board 172 being damaged at the corner.

[0187] Accordingly, the conductive connection portion 1723 extends between different sides of the motor, and forms a beveled angle transition portion 1724 between the portions extending on different sides. In the beveled angle transition portion 1724, the horizontal outer edge line on one side of the motor and the horizontal outer edge line on the other side of the motor each form an obtuse angle with the horizontal outer edge line between them; for example, in the beveled angle transition portion 1724 located at the fourth corner of the motor, the horizontal outer edge line between the fourth side of the motor and the first side of the motor forms an obtuse angle with both the fourth side and the first side of the motor; in the beveled angle transition portion 1724 located at the first corner of the motor... In section 24, the horizontal outer edge line between the first side of the motor and the second side of the motor forms obtuse angles with both the first and second side of the motor, respectively; in the oblique angle turning portion 1724 at the second corner of the motor, the horizontal outer edge line between the second and third side of the motor forms obtuse angles with both the second and third side of the motor, respectively.

[0188] It is worth mentioning that the conductive connection part 1723 can be made of a flexible circuit board, which can be a single flexible circuit board or multiple flexible circuit boards cut from a single flexible circuit board; the conductive connection part 1723 can also be directly formed from multiple conductive metal wires, with the conductive metal wires wrapped with insulating material to avoid short circuits.

[0189] Accordingly, in one embodiment of this application, the conductive connection portion 1723 includes at least two portions spaced apart in the circumferential direction. The conductive connection portion 1723 also includes at least one flap 1726, wherein the flap 1726 is located between every two adjacent portions spaced apart in the circumferential direction. Further, the flap 1726 is located at a corner of the motor, the corner of the motor being the intersection of different sides of the motor. For example, the intersection of the first and second sides of the motor is the first corner of the motor, the intersection of the second and third sides of the motor is the second corner of the motor, the intersection of the third and fourth sides of the motor is the third corner of the motor, and the intersection of the fourth and first sides of the motor is the fourth corner of the motor.

[0190] In one embodiment of this application, the conductive connection portion 1723 includes conductive connecting lines 1725, and the conductive connecting lines 1725 of the conductive connection portion 1723 have gaps, so that a complete conductive connecting line 1725 is divided into multiple (two or more) conductive connecting lines 1725. The conductive connection portion 1723 also includes a connecting band 1726 disposed on the multiple conductive connecting lines 1725, so that the multiple conductive connecting lines 1725 can move or deform together.

[0191] In one embodiment of this application, multiple conductive connecting lines 1725 in the conductive connecting portion 1723 are arranged in the circumferential direction of the motor.

[0192] The number of conductive connecting lines 1725 is set according to requirements. Considering that the focus sensing element 163 also needs to conduct electricity through the focus circuit board 172, in some embodiments, the conductive connection part 1723 includes at least two conductive connecting lines 1725, for example, two, four or six conductive connecting lines 1725. This is related to the specific model of the focus sensing element 163 and the connection method between the focus sensing element 163 and the focus coil 136.

[0193] In another embodiment of this application, the multiple conductive connecting lines 1725 in the conductive connecting portion 1723 are arranged in parallel. More specifically, the straight sections of the multiple conductive connecting lines 1725 that correspond to each other in the radial direction are parallel to each other, and the curved sections that correspond to each other in the radial direction are concentric circles.

[0194] In some embodiments, the conductive connection portion 1723 further includes an adhesive layer and an insulating layer. The insulating layer covers the outside of the conductive connection wire 1725 (i.e., the conductive metal wire), and the adhesive layer is located between the conductive metal wire and the insulating layer and is used to bond and fix the two together. The presence of the insulating layer and the adhesive layer can increase the structural strength of the conductive metal wire. In some embodiments, the insulating layer is formed of a polyimide film.

[0195] It should be understood that in this application, the height of the conductive connection portion 1723 in the optical axis direction D is much smaller than its width and length in the horizontal direction. The conductive connection portion 1723 is flat and horizontally disposed above the base 111, with a small height, which will not excessively increase the height of the motor 10. Furthermore, by reducing some material of the image stabilization carrier 121 or the base 111, the conductive connection portion 1723 can be arranged within the original height space of the motor, thus achieving the goal of not increasing the motor height. In particular, the plane of the conductive connection portion 1723 is perpendicular or nearly perpendicular to the plane of the image stabilization coil. While extending on the top surface of the base 111, the conductive connection portion 1723 is also located above the image stabilization coil. In this case, because of the horizontal arrangement of the conductive connection portion 1723, its impact on the height of the motor 10 is minimal, which is beneficial for achieving a smaller and more compact design for both the motor 10 and the camera module. Assuming the conductive connection 1723 is vertically arranged, when it is above the anti-shake coil, it will significantly increase the height of the motor 10, and when it is outside the anti-shake coil, it will increase the lateral dimension of the motor 10.

[0196] The orthographic projection of the conductive connection portion 1723 on the optical axis direction D at least partially overlaps with the first anti-shake coil 132 and the second anti-shake coil 134. It can also be further configured such that the orthographic projection of the conductive connection portion 1723 on the optical axis direction D does not exceed the first anti-shake coil 132 and the second anti-shake coil 134 in its width direction. This can reduce the amount of extra (exceeding the anti-shake carrier 121 and the anti-shake coil) lateral dimension occupied by the conductive connection portion 1723.

[0197] The orthographic projection of the conductive connection portion 1723 on the optical axis direction D does not overlap with 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.

[0198] The orthographic projection of the conductive connection portion 1723 in the optical axis direction D at least partially overlaps with the image stabilization carrier 121 and the base 111, wherein the area of ​​the portion of the conductive connection portion 1723 overlapping with the base 111 in the orthographic projection in the optical axis direction D is larger than the area of ​​the portion overlapping with the image stabilization carrier 121. In other words, most of the area of ​​the conductive connection portion 1723 is located above the base 111. This reduces the risk that, in the event of an accidental impact to the motor, the image stabilization carrier 121 may detach from the base 111 and impact the focusing circuit board 172, causing deformation or damage to the focusing circuit board 172.

[0199] In this application, the conductive connection portion 1723 needs to have a small elastic coefficient (K value) in the horizontal direction so that it can deform under a small force, thereby reducing the resistance to lateral deformation and minimizing its impact on the anti-shake function. However, in the optical axis direction D, i.e., the height direction, the conductive connection portion 1723 needs to have a large elastic coefficient (K value) so that the portion of the conductive connection portion 1723 away from the conductive movable portion 1722 and the conductive fixed portion 1721 is less likely to sag, thereby reducing the friction between the conductive connection portion 1723 and the base 111.

[0200] It is understandable that maintaining a low K value for the conductive connection 1723 in the horizontal direction while ensuring a high K value in the optical axis direction D is challenging. Therefore, a protrusion can be provided on the top surface of the base 111 corresponding to the conductive connection 1723 to prevent direct contact between the conductive connection 1723 and the top surface of the base 111. This reduces vibration, wear, or deformation of the conductive connection 1723.

[0201] Accordingly, in one embodiment of this application, at least one top surface protrusion 1116 is provided on the top surface of the base 111, and at least a portion of the conductive connection portion 1723 is supported on the top surface protrusion 1116 to prevent the conductive connection portion 1723 from falling and rubbing against the base 111 in the portion away from the conductive movable portion 1722 and the conductive fixed portion 1721. The conductive connection portion 1723 is substantially suspended above the base 111 under the support of the top surface protrusion 1116.

[0202] In embodiments of this application where the conductive connection portion 1723 does not have the conductive fixing portion 1721, the intermediate extension portion 1730 of the conductive connection portion 1723 is supported on the top surface protrusion 1116 to reduce the risk of the conductive connection portion 1723 falling off in the portion away from the first end 1710 and the second end 1720 and coming into direct contact with the base 111, in order to cope with the vibration, wear and deformation of the focusing circuit board 172.

[0203] The top surface protrusion 1116 can be formed on the top surface of the base 111 by integral molding with the base 111, bonding components, or directly applying adhesive. Preferably, the top surface protrusion 1116 is formed directly by applying adhesive, that is, the cured adhesive forms the top surface protrusion 1116. On the one hand, the height of the top surface protrusion 1116 formed directly by applying adhesive can be controlled to be relatively low. On the other hand, when multiple top surface protrusions 1116 are provided, it also helps to maintain the consistency of multiple top surface protrusions 1116, and the surface of the top surface protrusion 1116 formed by adhesive curing is usually relatively smooth with low friction. In addition, the top surface protrusion 1116 formed by adhesive curing has a certain degree of elasticity, which can play a role in vibration damping and deformation buffering to a certain extent. The adhesive is preferably an adhesive suitable for UV light (ultraviolet light) curing.

[0204] It should be understood that in other embodiments of this application, the top surface protrusion 1116 may not be provided.

[0205] It is worth mentioning that, in the embodiment of the focusing circuit board 172 of this application that includes the conductive fixing part 1721, the motor further includes a first pressing member 191 and a second pressing member 192. The first pressing member 191 is disposed on the outside of the conductive fixing part 1721, with a portion extending vertically and another portion bent horizontally relative to the portion extending vertically, and connected above the conductive connecting part 1723. It can apply pressure to the portion where the conductive connecting part 1723 is connected to the conductive fixing part 1721 to a certain extent, preventing the conductive connecting part 1723 from tilting upward relative to the conductive fixing part 1721. The second pressure member 192 is disposed on the outside of the conductive movable part 1722. A portion extends vertically, and another portion bends horizontally relative to the portion extending vertically, and is connected above the conductive connection part 1723. It can apply pressure to the portion where the conductive connection part 1723 is connected to the conductive movable part 1722 to a certain extent, preventing the conductive connection part 1723 from tilting upward relative to the conductive movable part 1722.

[0206] Furthermore, the first pressure member 191 and the second pressure member 192 are connected to the conductive connection portion 1723 and are spaced apart from the top surface of the base in the height direction of the motor, which can ensure to a certain extent that the conductive connection portion 1723 is suspended relative to the top surface of the base, especially the area of ​​the conductive connection portion 1723 adjacent to the first pressure member 191 and the second pressure member 192 is suspended relative to the top surface of the base.

[0207] It is worth mentioning that the second pressing member 192 and the focusing magnetic absorbing piece 152 can be the same component. In other words, the second pressing member 192 can be used as the focusing magnetic absorbing piece 152, or the focusing magnetic absorbing piece 152 can be used as the second pressing member. Accordingly, the focusing magnetic absorbing piece 152 is disposed on the outside of the conductive movable part 1722, with a portion extending vertically and another portion bent horizontally relative to the vertically extending portion, and connected above the conductive connecting part 1723. It can apply pressure to the portion where the conductive connecting part 1723 is connected to the conductive movable part 1722 to a certain extent, preventing the conductive connecting part 1723 from tilting upward relative to the conductive movable part 1722.

[0208] It is also worth mentioning that, in this embodiment, the focusing coil 136, the focusing sensing element 163, the first image stabilization coil 132, the second image stabilization coil 134, the first image stabilization sensing element 161, and the second image stabilization sensing element 162 are centrally connected through the base conductive insert 173, and are respectively connected to the base conductive insert 173 through an electrical connection structure that does not interfere with each other in the longitudinal space. The complexity of the conductive circuit is low. In particular, the first image stabilization coil 132, the second image stabilization coil 134, the first image stabilization sensing element 161, and the second image stabilization sensing element 162 are connected to the base conductive insert 173 through a relatively simple structure, and the conduction pressure of the conductive circuit is low.

[0209] Specifically, in this application, the focusing coil 136 and the focusing sensing element 163 are connected to the base conductive insert 173 through the focusing circuit board 172. More specifically, the outgoing conductive insert group 1732 connected to the base conductive insert 173 does not occupy the electrical connection structure between the first image stabilization coil 132, the second image stabilization coil 134, the first image stabilization sensing element 161 and the second image stabilization sensing element 162 and the outgoing conductive insert group 1732 of the base conductive insert 173.

[0210] The first anti-shake coil 132 is electrically connected to a portion of the coil conductive insert group 1731 in the base conductive insert 173, and then electrically connected to the output conductive insert group 1732 through the anti-shake circuit board 171 connected to the coil conductive insert group 1731; the second anti-shake coil 134 is electrically connected to another portion of the coil conductive insert group 1731 in the base conductive insert 173, and then electrically connected to the output conductive insert group 1732 through the anti-shake circuit board 171 connected to the coil conductive insert group 1731; wherein, the portion of the coil conductive insert group 1731 electrically connected to the first anti-shake coil 132 and the portion electrically connected to the second anti-shake coil 134 are spatially spaced apart and do not cross each other.

[0211] The first image stabilization sensing element 161 and the second image stabilization sensing element 162 are directly mounted at different positions on the image stabilization circuit board 171 and are electrically connected to the image stabilization circuit board 171, and then electrically connected to the lead-out conductive insert group 1732 of the base conductive insert 173 through the image stabilization circuit board 171. Since the first image stabilization sensing element 161 and the second image stabilization sensing element 162 are directly mounted at different positions on the image stabilization circuit board 171, the electrical connection structure between the first image stabilization sensing element 161 and the image stabilization circuit board 171 and the electrical connection structure between the second image stabilization sensing element 162 and the image stabilization circuit board 171 do not interfere with each other spatially.

[0212] The electrical connection structures between the first image stabilization sensing element 161 and the image stabilization circuit board 171, and between the first image stabilization coil 132 and the image stabilization circuit board 171, are spatially independent. Similarly, the electrical connection structures between the first image stabilization sensing element 161 and the image stabilization circuit board 171, and between the second image stabilization coil 134 and the image stabilization circuit board 171, are also spatially independent. The electrical connection structures between the second image stabilization sensing element 162 and the image stabilization circuit board 171, and between the first image stabilization coil 132 and the image stabilization circuit board 171, are also spatially independent.

[0213] It is worth mentioning that in this application, the focusing circuit board 172 is located on the fourth side of the image stabilization carrier 121, that is, on the side without a base sidewall, and on the upper side of the base 111 and the outer side of the sidewall of the base 111, close to the outer side of the motor 10. This facilitates electrical connection with the base conductive insert 173. It is not necessary to additionally set a transverse conductive structure that guides the motor 10 from its internal position near the center through multiple layers of internal structure to the sidewall of the base 111 to electrically connect the focusing circuit board 172 to the base conductive insert 173.

[0214] The portion of the coil conductive insert assembly 1731 used for electrically connecting the first anti-shake coil 132 and the portion used for electrically connecting the second anti-shake coil 134 are also located near the outside of the motor 10, facilitating electrical connection with the anti-shake circuit board 171.

[0215] Specifically, the portion of the coil conductive insert assembly 1731 used for electrically connecting the first image stabilization coil 132, the portion of the coil conductive insert assembly 1731 used for electrically connecting the second image stabilization coil 134, the conductive fixing portion 1721 in the focusing circuit board 172, and the conductive moving portion 1722 in the focusing circuit board 172 are respectively disposed on different sides of the motor 10, namely, the second side, the first side, the third side, and the fourth side, and extend in the vertical direction without interfering with each other.

[0216] In summary, the camera module and the motor 10 for the camera module according to the embodiments of this application have been explained. The motor 10 can reduce its height while achieving optical image stabilization and autofocus, thereby reducing the height of the camera module.
