Description

Focus anti-shake motor, camera module and electronic equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on April 2, 2024, with application number 202410397632.X and application name “A focus anti-shake motor, camera module and electronic equipment”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the field of camera technology, and in particular to a focus anti-shake motor, a camera module and electronic equipment. Background Art

[0003] With the popularization and development of electronic devices, taking photos and videos have become one of the common functions of electronic devices. In particular, electronic devices with optical image stabilization and autofocus functions are becoming more and more popular among users.

[0004] As user demands for photos and videos increase, the anti-shake drive mechanism bears a heavier load. The lens's own gravity can cause the lens to deflect in the direction of the anti-shake travel, affecting the industrial design (ID). Therefore, the anti-shake drive mechanism requires a larger electromagnetic drive force, resulting in a larger overall size. Summary of the Invention

[0005] The purpose of this application is to provide a focus anti-shake motor, a camera module and an electronic device, which are used to reduce the driving force required by the anti-shake drive mechanism and reduce the overall size of the anti-shake drive mechanism and the focus anti-shake motor.

[0006] According to a first aspect of an embodiment of the present application, a focus anti-shake motor is provided, comprising a focus base, a focus carrier, an anti-shake carrier, an anti-shake drive mechanism and a focus drive mechanism. The focus carrier is arranged on the focus base and is movably connected to the focus base along a first direction, and the focus carrier has a receiving space. The anti-shake carrier is arranged in the receiving space and is movably connected to the focus carrier in a plane perpendicular to the first direction. The anti-shake drive mechanism is arranged in the receiving space and is respectively connected to the focus carrier and the anti-shake carrier, and is used to drive the anti-shake carrier to move relative to the focus carrier in a direction perpendicular to the first direction. The focus drive mechanism is respectively connected to the focus base and the focus carrier, and is used to drive the focus carrier to move relative to the focus base in the first direction. The first direction is the stacking direction of the focus base, the focus carrier and the anti-shake carrier.

[0007] In the related art, the focus carrier is located inside the anti-shake carrier, and the anti-shake drive mechanism drives the anti-shake carrier and the focus carrier to move together. At this time, the components that need to move in the anti-shake stroke direction include the anti-shake carrier, the focus carrier, the lens mounted on the focus carrier, and the variable aperture, and their total gravity is relatively large. In order to prevent the lens from being offset in the anti-shake stroke direction due to its own gravity, affecting the appearance of the industrial design. Therefore, during the anti-shake movement, the anti-shake drive mechanism needs to provide a greater driving force to overcome some forces, such as gravity, and thus achieve anti-shake movement. Therefore, the required size of the anti-shake drive mechanism is relatively large, which in turn leads to the overall size of the product with the anti-shake drive mechanism being relatively large.

[0008] In the embodiment of the present application, the anti-shake carrier is arranged in the accommodating space of the focus carrier, and the focus carrier does not move in a direction perpendicular to the first direction. That is, during the anti-shake movement, the anti-shake drive mechanism does not need to drive the focus carrier to move. The maximum driving force that the anti-shake drive mechanism needs to provide is relatively small, the required size of the anti-shake drive mechanism is relatively small, and the overall size of the product with the anti-shake drive mechanism is relatively small. In addition, in some solutions, a portion of the anti-shake drive mechanism is fixed to the focus base. When the focus drive mechanism drives the focus carrier to move relative to the focus base in the first direction, the portion of the anti-shake drive mechanism connected to the focus carrier moves accordingly, thereby generating eccentricity, which affects the anti-shake accuracy. In the present application, the anti-shake drive mechanism is connected to the focus carrier and the anti-shake carrier respectively. When the focus drive mechanism drives the focus carrier to move relative to the focus base in the first direction, it drives the anti-shake carrier and the anti-shake drive mechanism to move together. That is, the anti-shake drive mechanism does not generate eccentric movement, thereby improving the anti-shake accuracy.

[0009] In an optional embodiment, the anti-shake carrier is a frame structure, and the two adjacent frames of the frame structure are a first frame and a second frame. The focus anti-shake motor includes two anti-shake drive mechanisms, namely a first anti-shake drive mechanism and a second anti-shake drive mechanism. The first anti-shake drive mechanism is connected to the first frame and the focus carrier, respectively. The second anti-shake drive mechanism is connected to the second frame and the focus carrier, respectively. The first anti-shake drive mechanism and the second anti-shake drive mechanism are respectively connected to the two adjacent frames of the anti-shake carrier, thereby respectively driving the anti-shake carrier to move in different directions on a plane perpendicular to the first direction, thereby realizing anti-shake displacement of the anti-shake carrier on the plane.

[0010] In an optional embodiment, the focus anti-shake motor further includes an intermediate sliding plate. The intermediate sliding plate is located on the side of the anti-shake carrier facing the focus base, and is stacked with the anti-shake carrier within the accommodation space. In a second direction, the intermediate sliding plate is movably connected to the focus carrier, and the anti-shake carrier abuts the intermediate sliding plate. A first anti-shake drive mechanism is used to drive the anti-shake carrier and the intermediate sliding plate to move relative to the focus carrier. In a third direction, the anti-shake carrier is movably connected to the intermediate sliding plate, and a second anti-shake drive mechanism is used to drive the anti-shake carrier to move relative to the intermediate sliding plate. The second direction is perpendicular to the first direction, and the third direction is perpendicular to both the first and second directions. In the first direction, the anti-shake carrier abuts the intermediate sliding plate. When the first anti-shake drive mechanism drives the anti-shake carrier in the second direction, it also drives the intermediate sliding plate to move relative to the focus carrier. In the third direction, the anti-shake carrier is movably connected to the intermediate sliding plate, and the second anti-shake drive mechanism drives the anti-shake carrier to move relative to the intermediate sliding plate, and thereby relative to the focus carrier. This achieves anti-shake displacement of the anti-shake carrier in the plane encompassing the second and third directions.

[0011] In an optional embodiment, the focus carrier includes an anti-shake base and an upper cover. The anti-shake base is disposed on the focus base. The upper cover is located on a side of the anti-shake carrier facing away from the anti-shake base. The upper cover is disposed on the anti-shake base and connected to the anti-shake base. The anti-shake base and the upper cover define a storage space. The anti-shake drive mechanism includes an upper anti-shake drive mechanism and a lower anti-shake drive mechanism. The upper anti-shake drive mechanism is located between the upper cover and the anti-shake carrier and is connected to the upper cover and the anti-shake carrier, respectively. The lower anti-shake drive mechanism is located between the anti-shake base and the anti-shake carrier and is connected to the anti-shake base and the anti-shake carrier, respectively. Both the anti-shake carrier and the anti-shake drive mechanism are disposed in the storage space defined by the anti-shake base and the upper cover. In a first direction, the upper cover can limit the anti-shake carrier and the anti-shake drive mechanism to prevent the anti-shake carrier from leaving the storage space. The upper and lower anti-shake drive mechanisms are disposed on either side of the anti-shake carrier, respectively, to increase the driving force of the anti-shake drive mechanism on the anti-shake carrier.

[0012] In one optional embodiment, the upper anti-shake drive mechanism includes a first coil and a first magnet. The first coil is connected to the side of the upper cover facing the anti-shake carrier, and the first magnet is connected to the side of the anti-shake carrier facing the upper cover. The lower anti-shake drive mechanism includes a second coil and a second magnet. The second coil is connected to the side of the anti-shake base facing the anti-shake carrier, and the second magnet is connected to the side of the anti-shake carrier facing the anti-shake base. The first coil and the second coil are located on either side of the first magnet and the second magnet, respectively, fully utilizing the magnetic fields of the first magnet and the second magnet on both sides of the first direction to increase the driving force of the upper and lower anti-shake drive mechanisms, thereby reducing the size of the anti-shake drive mechanisms. In addition, along the first direction, the direction of the force generated by the first coil and the first magnet is opposite to the direction of the force generated by the second coil and the second magnet. Therefore, after both the first magnet and the second magnet are connected to the anti-shake carrier, the two sets of forces can weaken each other, reducing the anti-shake carrier's tendency to move in the first direction. Furthermore, the first coil, which requires power to operate, is connected to the upper cover. When the first magnet drives the anti-shake carrier for anti-shake movement, the upper cover does not need to move with the carrier, meaning the first coil does not need to move, facilitating power supply. Similarly, the second coil, which requires power to operate, is connected to the anti-shake base. When the second magnet drives the anti-shake carrier for anti-shake movement, the anti-shake base does not need to move with the carrier, meaning the second coil does not need to move either, facilitating power supply.

[0013] In an optional embodiment, a first groove is provided on the surface of the anti-shake carrier facing the upper cover. The first magnet is located in the first groove. A second groove is provided on the surface of the anti-shake carrier facing the anti-shake base. The second magnet is located in the second groove. The first groove accommodates the first magnet, thereby limiting the first magnet and preventing it from detaching from the anti-shake carrier. The second groove accommodates the second magnet, thereby limiting the second magnet and preventing it from detaching from the anti-shake carrier. In addition, by arranging the first magnet in the first groove and the second magnet in the second groove, the total thickness of the first magnet, the anti-shake carrier and the second magnet in the first direction can be reduced, thereby reducing the size of the focus anti-shake motor.

[0014] In one optional embodiment, the anti-shake carrier includes a first plastic component and a first magnetic conductive sheet. The first magnetic conductive sheet is embedded in the first plastic component. A portion of the first magnetic conductive sheet forms the bottom of the first and second grooves. Under the action of magnetic force, the first and second magnets, respectively, exert a force toward each other with the first magnetic conductive sheet, further ensuring the stability of the connection between the first and second magnets and the anti-shake carrier, and reducing the possibility of the anti-shake drive mechanism detaching from the anti-shake carrier.

[0015] In one optional embodiment, the first magnet and the second magnet are connected to form an integral structural component. A through hole is defined on the anti-shake carrier, extending through the anti-shake carrier. The integral structural component is embedded in the through hole. The first and second magnets are an integral structural component, facilitating the installation of the anti-shake drive mechanism and the anti-shake carrier.

[0016] In an optional embodiment, the focus anti-shake motor further includes a first moving part. The first moving part is located on the side of the anti-shake carrier facing the anti-shake base, and is disposed between the anti-shake base and the anti-shake carrier. In a plane perpendicular to the first direction, the anti-shake carrier is movably connected to the anti-shake base via the first moving part. Exemplarily, the first moving part may be a ball, an ultra-sliding ball, or a sliding column. By providing the first moving part between the focus carrier and the anti-shake carrier, the resistance to relative movement between the focus carrier and the anti-shake carrier is reduced, thereby reducing the power required by the anti-shake drive mechanism, and thereby reducing the size of the anti-shake drive mechanism.

[0017] In one optional embodiment, the anti-shake carrier includes four corners. The focus anti-shake motor includes multiple first moving parts, and these first moving parts are arranged between at least three corners of the anti-shake carrier and the anti-shake base. The first moving parts distributed at the three corners of the anti-shake carrier support the anti-shake carrier, ensuring that the anti-shake carrier does not directly contact the anti-shake base, thereby reducing friction between the anti-shake base and the anti-shake carrier.

[0018] In an optional embodiment, the focus anti-shake motor further includes a second magnetic conductive sheet. Along the first direction, the second magnetic conductive sheet and the anti-shake carrier are stacked on the anti-shake base. The second magnetic conductive sheet is connected to the anti-shake base. The second magnetic conductive sheet is used to adsorb with the second magnet. At this time, the second magnetic conductive sheet is connected to the anti-shake base, and the second magnet is connected to the anti-shake carrier. When there is an adsorption force between the second magnet and the second magnetic conductive sheet, there is a force between the anti-shake carrier and the anti-shake base, thereby pressing the first moving part arranged between the focus carrier and the anti-shake carrier to prevent the first moving part from being separated from between the focus carrier and the anti-shake carrier.

[0019] In an optional embodiment, the focusing base includes a bottom and a side that are connected to each other, and the focusing drive mechanism includes a focusing coil and a focusing magnet. The focusing coil is arranged on the focusing carrier and is connected to the focusing carrier. The focusing magnet is arranged on the side and is connected to the side. Along the first direction, the focusing magnet is used to drive the focusing coil and the focusing carrier to move relative to the side. The focus anti-shake motor also includes a driving chip. The driving chip is connected to the focusing carrier and is electrically connected to the focusing coil. The driving chip and the focusing coil are both arranged on the focusing carrier, that is, the driving chip and the focusing coil will not produce relative movement, which facilitates the electrical connection between the focusing coil and the driving chip. In addition, in the first direction, the thickness of the focusing coil, the focusing magnet, and the focusing carrier overlap, thereby reducing the thickness of the focus anti-shake motor.

[0020] In another optional embodiment, the focusing base includes a bottom and a side portion connected to each other, and the focusing drive mechanism includes a focusing coil and a focusing magnet. The focusing coil is arranged on the side portion and connected to the side portion. The focusing magnet is arranged on the focusing carrier and connected to the focusing carrier. Along a first direction, the focusing coil is used to drive the focusing magnet and the focusing carrier to move relative to the side portion. The focusing coil is arranged on the side portion that does not need to move in the first direction to facilitate powering the focusing coil.

[0021] In an optional embodiment, the focus and anti-shake motor further includes at least one second moving member, located on the side of the side portion facing the focus carrier and disposed between the focus carrier and the side portion. This second moving member disposed between the focus carrier and the side portion reduces frictional resistance during relative motion between the focus carrier and the anti-shake carrier, thereby reducing the power required by the focus drive mechanism and thereby reducing the size of the focus drive mechanism.

[0022] In an optional embodiment, a first slide groove and a second slide groove are provided on the side of the side facing the focus carrier. At least one second moving part includes a first slide post and a second slide post. A portion of the first slide post is arranged in the first slide groove, and another portion of the first slide post abuts the focus carrier. A portion of the second slide post is arranged in the second slide groove, and another portion of the second slide post abuts the focus carrier. The first slide post is accommodated by the first slide groove on the side, and the first slide post abuts the focus carrier, and then the first slide post is limited by the first slide groove and the focus carrier to prevent the first slide post from being separated from between the focus carrier and the side. Similarly, the second slide groove accommodates the second slide post, and the portion of the second slide post located outside the second slide groove also abuts the focus carrier, and then the second slide post is limited by the second slide groove and the focus carrier to prevent the second slide post from being separated from between the focus carrier and the side.

[0023] In one optional embodiment, a third and fourth slide grooves are provided on one side of the focus carrier facing the side. Another portion of the first slide post is located within the third slide groove, and another portion of the second slide post is located within the fourth slide groove. The third slide groove provided on the focus carrier further restrains the first slide post. Similarly, the fourth slide groove provided on the focus carrier further restrains the second slide post.

[0024] In an optional embodiment, the third slide groove is V-shaped, and the fourth slide groove is U-shaped. There is a gap between the second slide post and the groove wall of the fourth slide groove that is away from or toward the third slide groove. The third slide groove is V-shaped, and the width of the V-shaped groove decreases greatly along the groove depth direction. At this time, the other part of the first slide post is set in the V-shaped groove to ensure that the first slide post abuts against the groove wall of the V-shaped groove, thereby ensuring that the focusing carrier moves relative to the focusing base along the extension direction of the V-shaped groove. In addition, the fourth slide groove is U-shaped, and the width of the U-shaped groove decreases less along the groove depth direction. There is a gap between the second slide post and the groove wall of the fourth slide groove that is away from or toward the third slide groove, providing installation margin, thereby ensuring that when the focusing carrier is installed with the side, the other part of the second slide post can be installed in the fourth slide groove.

[0025] In an optional embodiment, the focus anti-shake motor further includes at least one elastic member, one end of the elastic member being connected to the focus carrier and the other end being connected to the anti-shake carrier, with the elastic member elastically deforming in a direction perpendicular to the first direction. When the anti-shake drive mechanism drives the anti-shake carrier to move in a plane perpendicular to the first direction, the elastic member elastically deforms. When the anti-shake drive mechanism stops operating, the force generated by the elastic deformation of the elastic member resets the anti-shake carrier, thereby centering the anti-shake carrier. Furthermore, the elastic member can provide anti-torsion force to the anti-shake carrier, hindering its rotation.

[0026] In one optional embodiment, the focus stabilization motor includes four elastic members, and the stabilization carrier includes four corners, with the four elastic members correspondingly positioned at each corner. The four elastic members correspondingly positioned at the four corners, and thus the elastic deformation of the four elastic members, increase the force pushing the stabilization carrier back to its original position, ensuring the stabilization carrier's centering. Furthermore, the four elastic members increase the stabilization carrier's torsional strength, further hindering its rotation.

[0027] In an optional embodiment, the anti-shake carrier includes a first plastic part and a boss. The boss is arranged on the side of the first plastic part away from the focusing base and is connected to the first plastic part. The elastic part includes a first connecting part, an elastic part and a second connecting part. The first connecting part is connected to the focusing carrier. The elastic part is connected to the first connecting part. The second connecting part is connected to the elastic part and is provided with a mounting hole. One end of the boss extends into the mounting hole and abuts or connects with the second connecting part. The boss cooperates with the second connecting part to achieve relative fixation of the second connecting part and the anti-shake carrier. When the focusing carrier and the anti-shake carrier move relative to each other, the first connecting part and the second connecting part are driven to move relative to each other. At this time, the elastic part is deformed. When the anti-shake drive mechanism stops working, the elastic part pushes the second connecting part to reset, thereby driving the anti-shake carrier to reset, thereby achieving the centering of the anti-shake carrier.

[0028] In an optional embodiment, the focus carrier includes a second plastic part and a metal bracket. The metal bracket is embedded in the second plastic part, and the end of the metal bracket facing away from the focus base protrudes from the second plastic part. The focus anti-shake motor includes a circuit board and an elastic member. The circuit board is arranged on the focus base and connected to the focus base. The end of the metal bracket facing the focus base is electrically connected to the circuit board. The elastic member includes at least one of a conductive spring and a conductive suspension wire. The elastic member is electrically connected to the end of the metal bracket facing away from the focus base, and the elastic member is used to be electrically connected to the variable aperture.

[0029] The elastic member connects the variable aperture to the metal bracket. By supplying power to the circuit board, the current is transmitted to the metal bracket, which is electrically connected to the circuit board. This current is then carried through the elastic member, which in turn powers the variable aperture. When the focus and anti-shake motor is used in a camera module, the variable aperture is mounted on the anti-shake carrier. When the anti-shake carrier drives the variable aperture to move relative to the focus carrier, the elastic member deforms itself, preventing disconnection between the metal bracket and the elastic member, and between the elastic member and the variable aperture, thereby ensuring stable power supply. The metal bracket also increases the rigidity of the focus carrier, ensuring its mechanical strength.

[0030] In an optional embodiment, the circuit board includes a first flexible board and a second flexible board. The first flexible board is arranged on one side of the focusing carrier and is connected to the metal bracket. Along the first direction, the second flexible board is arranged between the focusing base and the focusing carrier, and the first end of the second flexible board is connected to the first flexible board, and the second end of the second flexible board is connected to the focusing base. When the focusing carrier moves relative to the focusing base, the elastic deformation of the second flexible board causes the first end of the second flexible board to move with the focusing carrier, while the second end is still connected to the focusing base, thereby ensuring that during the movement of the focusing carrier, power is supplied to the second end of the second flexible board, and the current is transmitted through the first flexible board to the metal bracket and the elastic member, thereby powering the variable aperture.

[0031] It is understood that the first flexible board and the second flexible board can be flexible circuit boards of an integrated structure. Of course, the first flexible board and the second flexible board can also both be flexible circuit boards, and the two flexible circuit boards can be connected.

[0032] In one optional embodiment, the second flexible plate is L-shaped or U-shaped. In this case, if the distance between the two ends of the second flexible plate is the same, the L-shaped or U-shaped structure is longer, thereby having better deformation capability. This ensures that when the focus carrier and focus base move, the force required to deform the second flexible plate is small, thereby reducing the maximum driving force required by the focus drive mechanism and reducing the size of the focus drive mechanism.

[0033] In an optional embodiment, the focus drive mechanism is connected to the first side wall of the focus carrier. The first flexible plate is connected to the portion of the second side wall of the focus carrier facing the first side wall. The first side wall and the second side wall are adjacent to each other. The focus drive mechanism and the first flexible plate are respectively located on different side walls of the focus carrier, which is convenient for installation and arrangement. In addition, when the focus drive mechanism drives the focus carrier to move relative to the focus base, its force is mainly concentrated on the first side wall connected to the focus drive mechanism. The first flexible plate is connected to the portion of the second side wall facing the first side wall. In other words, the position of the reaction force exerted by the first flexible plate and the second flexible plate on the focus carrier is close to the position of the force exerted by the focus drive mechanism on the focus carrier, so as to reduce the tipping arm and torque of the reaction force.

[0034] A second aspect of the present application provides a camera module comprising the aforementioned focus and anti-shake motor and a variable aperture. The variable aperture is connected to an anti-shake carrier. This camera module has the same technical effects as the focus and anti-shake motor provided in the aforementioned embodiment and will not be further described here.

[0035] In a third aspect of the embodiments of the present application, an electronic device is provided, comprising a housing and the aforementioned camera module. The camera module is disposed within the housing. The aforementioned electronic device has the same technical effects as the camera module provided in the aforementioned embodiments, and will not be further described here.

[0056] In the drawings of the embodiments of the present application, components are represented by straight line guide lines with arrows; parts are represented by only straight line guide lines; hollow structures such as cavities and openings are represented by curved line guide lines.

[0057] An embodiment of the present application provides an electronic device 100. As shown in FIG1 , the electronic device 100 may include a camera module 200 and a housing 300. The camera module 200 is disposed in the housing 300, and the housing 300 may protect the camera module 200. The camera module 200 may have a photo-taking function. The electronic device 100 may be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, an in-vehicle device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses or a VR helmet, etc., having a camera module 200. The embodiment of the present application does not impose any special restrictions on the specific form of the above-mentioned electronic device 100.

[0058] The housing 300 is provided with a light-transmitting hole 301 for exposing a portion of the camera module 200 . The camera module 200 is used to collect ambient light entering the interior of the electronic device 100 through the light-transmitting hole 301 .

[0059] The following illustrates the structure of the camera module 200. In some embodiments of the present application, as shown in FIG2 , the camera module 200 may include a housing 02 . The housing 02 has a cavity (not shown). The housing 02 also has an opening 021 that communicates with the cavity. The housing 02 is used to protect internal components.

[0060] As shown in Figure 3A, the camera module 200 may include a lens 03. The lens 03 may include one or more optical lenses. The optical lenses may be convex lenses or concave lenses, so that the lens 03 with the optical lenses can use the refraction principle of optical lenses to converge the light of the subject onto the focal plane of the camera module 200 for imaging. The multiple optical lenses are arranged in sequence along the optical axis OO of the lens 03.

[0061] Continuing with FIG3A , the camera module 200 may further include a variable aperture 04 . The variable aperture 04 is located on the light-entering side of the lens 03 . The opening 021 is used to expose the variable aperture 04 . The variable aperture 04 can adjust the amount of external light entering the lens 03 .

[0062] 3A , the camera module 200 may further include a focus anti-shake motor 01. For ease of explanation, the direction parallel to the optical axis OO is the Z axis, and the two directions perpendicular to each other and both perpendicular to the optical axis OO are the X axis and the Y axis, respectively, and the X axis and the Y axis are both located in the XY plane. Below, the Z axis direction is the first direction, the X axis direction is the second direction, and the Y axis direction is the third direction for explanation. As shown in FIG3B (a cross-sectional view obtained along the P1-P2 direction in FIG2 ), the variable aperture 04 and the lens 03 are respectively connected to the focus anti-shake motor 01 (as shown in FIG3A ). At this time, the focus anti-shake motor 01 can drive the lens 03 and the variable aperture 04 to move along the first direction Z to achieve auto focus (AF). In addition, the focus anti-shake motor 01 can also drive the lens 03 and the variable aperture 04 to move in the XY plane to achieve optical image stabilization (OIS).

[0063] However, in the related art, as shown in Figure 4, the camera module sets the focus actuator 31 inside the anti-shake actuator 32. That is, the anti-shake drive mechanism (not shown in the figure) needs to drag the anti-shake actuator 32 and the focus actuator 31 to move together. At this time, the components that need to move in the direction perpendicular to the first direction Z include the anti-shake actuator 32, the focus actuator 31, the lens 03 mounted on the focus actuator 31, and the variable aperture 04, and their total gravity is relatively large. The driving force required by the anti-shake drive mechanism is relatively large. In addition, in order to prevent the lens 03 from being offset in the direction perpendicular to the first direction Z due to its own gravity, affecting the industrial design of the appearance. Therefore, it is necessary to add other components (such as springs or magnetic components, not shown in the figure) to provide a reaction force that can offset gravity (for example, the Y direction in Figure 4). During the anti-shake movement, the anti-shake motor needs to provide a larger driving force to overcome some forces, such as gravity and spring reaction force or magnetic reaction force, thereby achieving anti-shake movement. Therefore, the required anti-shake driving mechanism is relatively large in size, which leads to the overall size of the camera module with the anti-shake driving mechanism being relatively large.

[0064] To address the aforementioned issues, in some embodiments of the present application, as shown in FIG5 , the aforementioned focus and anti-shake motor 01 may include a focus base 11, a focus carrier 12, an anti-shake carrier 13, and an anti-shake drive mechanism 14. The focus carrier 12 may be mounted on the focus base 11 and movably connected to the focus base 11 along a first direction Z. The focus carrier 12 has a receiving space 121. The anti-shake carrier 13 is mounted within the receiving space 121 and movably connected to the focus carrier 12 in an XY plane perpendicular to the first direction Z. The first direction Z is the stacking direction of the focus base 11, the focus carrier 12, and the anti-shake carrier 13. The anti-shake drive mechanism 14 is mounted within the receiving space 121 and connected to the focus carrier 12 and the anti-shake carrier 13, respectively. The anti-shake drive mechanism 14 is configured to drive the anti-shake carrier 13 to move relative to the focus carrier 12 in a direction perpendicular to the first direction Z (i.e., in the XY plane) to achieve optical image stabilization.

[0065] At this time, the focus carrier 12 does not need to move relative to the focus base 11 on the XY plane, that is, the anti-shake drive mechanism 14 does not need to drive the focus carrier 12 to move, that is, when optical image stabilization is performed, the focus carrier 12 does not need to move relative to the focus base 11. The total gravity required to drive the anti-shake drive mechanism 14 is relatively small, and the maximum driving force required to be provided by the anti-shake drive mechanism 14 is relatively small. Moreover, the gravity of the focus carrier 12 does not participate in the anti-shake stroke offset, reducing the total gravity of components that may be directional offset in the XY plane, and the reaction force required to be provided by other components (such as springs or magnetic components) that need to be added to offset this gravity can be relatively small. During the anti-shake movement, the maximum driving force required to be provided by the anti-shake motor is relatively small, the required size of the anti-shake motor is relatively small, and the overall size of the lens 03 module with the anti-shake drive mechanism 14 is relatively large.

[0066] In some embodiments, a portion of the anti-shake drive mechanism 14 is fixed to the focus base 11. When the focus drive mechanism 15 drives the focus carrier 12 to move relative to the focus base 11 along the first direction Z, the portion of the anti-shake drive mechanism 14 connected to the focus carrier 12 moves accordingly, thereby causing eccentricity and affecting the anti-shake accuracy.

[0067] To address the aforementioned issues, as further illustrated in FIG5 , the aforementioned focus and anti-shake motor 01 may include a focus drive mechanism 15. The focus drive mechanism 15 may be connected to the focus base 11 and the focus carrier 12, respectively, to drive the focus carrier 12 to move relative to the focus base 11 in a first direction Z to achieve autofocus. The anti-shake drive mechanism 14 is connected to the focus carrier 12 and the anti-shake carrier 13, respectively. When the focus drive mechanism 15 drives the focus carrier 12 to move relative to the focus base 11 in the first direction Z, it also drives the anti-shake carrier 13 and the anti-shake drive mechanism 14 to move together. This means that the anti-shake drive mechanism 14 does not produce eccentric motion, thereby improving anti-shake accuracy.

[0068] Furthermore, as shown in FIG6 , the anti-shake carrier 13 may be a frame structure, and the two adjacent frames of the frame structure are a first frame 131A and a second frame 131B. Continuing with FIG5 , the focus anti-shake motor 01 may include two anti-shake drive mechanisms 14, namely a first anti-shake drive mechanism 14A and a second anti-shake drive mechanism 14B. The first anti-shake drive mechanism 14A is respectively connected to the first frame 131A (as shown in FIG6 ) and the focus carrier 12. The second anti-shake drive mechanism 14B is respectively connected to the second frame 131B (as shown in FIG6 ) and the focus carrier 12. The first anti-shake drive mechanism 14A and the second anti-shake drive mechanism 14B are respectively connected to the two adjacent frames of the anti-shake carrier 13, thereby respectively driving the anti-shake carrier 13 to move in different directions on the XY plane perpendicular to the first direction Z, thereby realizing anti-shake displacement of the anti-shake carrier 13 on the plane.

[0069] Continuing with Figure 5, the focus carrier 12 may include an anti-shake base 122 and an upper cover 123. The anti-shake base 122 is disposed on the focus base 11. The upper cover 123 is located on the side of the anti-shake carrier 13 facing away from the anti-shake base 122. The upper cover 123 is mounted on the anti-shake base 122 and connected to the anti-shake base 122. The anti-shake base 122 and the upper cover 123 enclose a receiving space 121. The anti-shake drive mechanism 14 may include an upper anti-shake drive mechanism 141 and a lower anti-shake drive mechanism 142. The upper anti-shake drive mechanism 141 is located between the upper cover 123 and the focus carrier 13. The upper anti-shake drive mechanism 141 is connected to the upper cover 123 and the focus carrier 13, respectively. The lower anti-shake drive mechanism 142 is located between the anti-shake base 122 and the focus carrier 13. The lower anti-shake drive mechanism 142 is connected to the anti-shake base 122 and the focus carrier 13, respectively. The anti-shake carrier 13 and the anti-shake drive mechanism 14 are both disposed in the accommodation space 121 enclosed by the anti-shake base 122 and the upper cover 123 , in the first direction Z. By controlling the driving directions of the upper anti-shake drive mechanism 141 and the lower anti-shake drive mechanism 142 , the driving directions of the upper anti-shake drive mechanism 141 and the lower anti-shake drive mechanism 142 have the same directional components, thereby increasing the driving force of the anti-shake drive mechanism 14 on the anti-shake carrier 13 .

[0070] It is understood that the first anti-shake drive mechanism 14A may include an upper anti-shake drive mechanism 141 and a lower anti-shake drive mechanism 142. The second anti-shake drive mechanism 14B may also include an upper anti-shake drive mechanism 141 and a lower anti-shake drive mechanism 142.

[0071] Continuing with FIG5 , the upper anti-shake drive mechanism 141 may include a first coil 1411 and a first magnet 1412. The first coil 1411 is connected to the side of the upper cover 123 facing the anti-shake carrier 13, and the first magnet 1412 is connected to the side of the anti-shake carrier 13 facing the upper cover 123. The lower anti-shake drive mechanism 142 includes a second coil 1421 and a second magnet 1422. The second coil 1421 is connected to the side of the anti-shake base 122 facing the anti-shake carrier 13, and the second magnet 1422 is connected to the side of the anti-shake carrier 13 facing the anti-shake base 122. Along the first direction Z, the first coil 1411 and the second coil 1421 are located on either side of the first magnet 1412 and the second magnet 1422, respectively. A magnetic field is generated on both sides of the first magnet 1412. At this point, the first coil 1411 and the second coil 1421 are located within the magnetic field of the first magnet 1412, respectively. Consequently, the first coil 1411 and the second coil 1421 can utilize the magnetic field of the first magnet 1412 to generate a driving force. Similarly, a magnetic field is generated on both sides of the second magnet 1422. At this point, the first coil 1411 and the second coil 1421 are located within the magnetic field of the second magnet 1422, respectively. Consequently, the first coil 1411 and the second coil 1421 can utilize the magnetic field of the second magnet 1422 to generate a driving force. This improves the driving force of the upper and lower anti-shake drive mechanisms 141 and 142, thereby reducing the size of the anti-shake drive mechanism 14.

[0072] Moreover, along the first direction Z, the first coil 1411 and the first magnet 1412 will also generate a force that moves them closer to or away from each other. Similarly, the second coil 1421 and the second magnet 1422 will also generate a force that moves them closer to or away from each other. By controlling the magnitude and direction of the current in the first coil 1411 and the second coil 1421, the direction of the force generated by the first coil 1411 and the first magnet 1412 can be made opposite to the direction of the force generated by the second coil 1421 and the second magnet 1422. Then, after the first magnet 1412 and the second magnet 1422 are both connected to the anti-shake carrier 13, the two sets of forces can weaken each other, reducing the movement tendency of the anti-shake carrier 13 in the first direction Z, and preventing the anti-shake carrier 13 from moving in the first direction Z and affecting the focusing accuracy. Furthermore, the first coil 1411, which requires power to operate, is connected to the upper cover 123. When the first magnet 1412 drives the anti-shake carrier 13 to perform anti-shake movement, the upper cover 123 does not need to move with the anti-shake carrier 13, that is, the first coil 1411 does not need to move, thus facilitating power supply to the first coil 1411. Similarly, the second coil 1421, which requires power to operate, is connected to the anti-shake base 122. When the second magnet 1422 drives the anti-shake carrier 13 to perform anti-shake movement, the anti-shake base 122 also does not need to move with the anti-shake carrier 13, that is, the second coil 1421 does not need to move, thus facilitating power supply to the second coil 1421.

[0073] In some embodiments, as shown in FIG7 (a cross-sectional view taken along the N1-N2 direction in FIG6 ), a first groove 131 is provided on the surface of the anti-shake carrier 13 facing the upper cover 123 (as shown in FIG5 ). The first magnet 1412 is located in the first groove 131. A second groove 132 is provided on the surface of the anti-shake carrier 13 facing the anti-shake base 122 (as shown in FIG5 ). The second magnet 1422 is located in the second groove 132. The first magnet 1412 is accommodated by the first groove 131, thereby limiting the position of the first magnet 1412 and preventing it from detaching from the anti-shake carrier 13. The second magnet 1422 is accommodated by the second groove 132, thereby limiting the position of the second magnet 1422 and preventing it from detaching from the anti-shake carrier 13. In addition, the first magnet 1412 is set in the first groove 131 and the second magnet 1422 is set in the second groove 132. This can reduce the thickness of the focus anti-shake motor in the first direction Z after the first magnet 1412, the anti-shake carrier 13, and the second magnet 1422 are assembled, thereby reducing the size of the focus anti-shake motor 01.

[0074] Continuing with FIG7 , the anti-shake carrier 13 may include a first plastic component 133 and a first magnetic conductive sheet 134. The first magnetic conductive sheet 134 is embedded within the first plastic component 133. A portion of the first magnetic conductive sheet 134 forms the bottom 111 of the first and second grooves 131 and 132. The first magnet 1412 and the second magnet 1422 each have magnetic attraction with the first magnetic conductive sheet 134, further ensuring the connection stability between the first magnet 1412 and the second magnet 1422 and the anti-shake carrier 13, thereby reducing the possibility of the anti-shake drive mechanism 14 being separated from the anti-shake carrier 13.

[0075] In other embodiments, as shown in Figure 8 (a cross-sectional view taken along the N1-N2 direction in Figure 6 ), the first magnet 1412 and the second magnet 1422 are connected to form an integral structural component. A through hole 135 is defined in the anti-shake carrier 13, extending through the anti-shake carrier 13. The integral structural component is embedded in the through hole 135. The first magnet 1412 and the second magnet 1422 are an integral structural component, facilitating the installation of the anti-shake drive mechanism 14 and the anti-shake carrier 13.

[0076] Continuing with FIG9 , the focus anti-shake motor 01 may further include a first moving part 16. The first moving part 16 is located on the side of the anti-shake carrier 13 facing the anti-shake base 122. As shown in FIG3B , the first moving part 16 is disposed between the anti-shake base 122 and the anti-shake carrier 13. In the XY plane perpendicular to the first direction Z, the anti-shake carrier 13 is movably connected to the anti-shake base 122 via the first moving part 16. For example, the first moving part 16 may be a ball, an ultra-sliding ball, or a sliding column. By disposing the first moving part 16 between the focus carrier 12 and the anti-shake carrier 13, the contact area between the focus carrier 12 and the anti-shake carrier 13 can be reduced, thereby reducing the resistance during relative movement between the focus carrier 12 and the anti-shake carrier 13, thereby reducing the power required to be provided by the anti-shake drive mechanism 14, and thereby reducing the size of the anti-shake drive mechanism 14.

[0077] Continuing with FIG9 , the anti-shake carrier 13 may be a frame structure having four frames, with adjacent frames intersecting to form four corners 136. The focus anti-shake motor 01 may include multiple first moving parts 16, with these first moving parts 16 disposed between at least three corners 136 of the anti-shake carrier 13 and the anti-shake base 122. The first moving parts 16 distributed at the three corners 136 of the anti-shake carrier 13 provide support for the anti-shake carrier 13, ensuring that the anti-shake carrier 13 does not directly contact the anti-shake base 122, thereby reducing friction between the anti-shake base 122 and the anti-shake carrier 13.

[0078] In the embodiment shown in FIG. 9 , first moving parts 16 are disposed between the four corners 136 of the anti-shake carrier 13 and the anti-shake base 122 .

[0079] Continuing with FIG9 , the focus anti-shake motor 01 may further include a second magnetic conductive sheet 17. Along the first direction Z, the second magnetic conductive sheet 17 and the anti-shake carrier 13 are stacked on the anti-shake base 122. The second magnetic conductive sheet 17 is connected to the anti-shake base 122. The second magnetic conductive sheet 17 is used to be adsorbed with the second magnet 1422. At this time, the second magnetic conductive sheet 17 is connected to the anti-shake base 122, and the second magnet 1422 is connected to the anti-shake carrier 13. When there is an adsorption force between the second magnet 1422 and the second magnetic conductive sheet 17, there is a force that brings the anti-shake carrier 13 and the anti-shake base 122 closer to each other, thereby pressing the first moving part 16 arranged between the focus carrier 12 and the anti-shake carrier 13 to prevent the first moving part 16 from being separated from between the focus carrier 12 and the anti-shake carrier 13.

[0080] The embodiments shown in Figures 3B and 9 above are based on the example of the anti-shake carrier 13 and the focus carrier 12 both abutting against the first moving member 16. In other embodiments of the present application, as shown in Figure 10 , the focus anti-shake motor 01 may further include an intermediate sliding plate 18. The intermediate sliding plate 18 is located on the side of the anti-shake carrier 13 facing the focus base 11 and is stacked with the anti-shake carrier 13 within the accommodating space 121. Along the second direction X, the intermediate sliding plate 18 is movably connected to the focus carrier 12, abutting the anti-shake carrier 13 against the intermediate sliding plate 18. The first anti-shake drive mechanism 14A (shown in Figure 5 ) is used to drive the anti-shake carrier 13 and the intermediate sliding plate 18 to move relative to the focus carrier 12. Along the third direction Y, the anti-shake carrier 13 is movably connected to the intermediate sliding plate 18, and the second anti-shake drive mechanism 14B is used to drive the anti-shake carrier 13 to move relative to the intermediate sliding plate 18. The second direction X is perpendicular to the first direction Z, and the third direction Y is perpendicular to both the first direction Z and the second direction X. At this time, in the first direction Z, the anti-shake carrier 13 abuts the intermediate sliding plate 18. When the first anti-shake driving mechanism 14A drives the anti-shake carrier 13 to move in the second direction X, it drives the intermediate sliding plate 18 to move relative to the focus carrier 12. In the third direction Y, the anti-shake carrier 13 is movably connected to the intermediate sliding plate 18, and the second anti-shake driving mechanism 14B drives the anti-shake carrier 13 to move relative to the intermediate sliding plate 18, and then relative to the focus carrier 12. This achieves anti-shake displacement of the anti-shake carrier 13 in the plane containing the second direction X and the third direction Y.

[0081] In some embodiments, as shown in Figure 9 , the focus base 11 may include a bottom portion 111 and a side portion 112 connected to each other, and the focus drive mechanism 15 (as shown in Figure 5 ) may include a focus coil 151 and a focus magnet 152. The focus coil 151 is disposed on and connected to the focus carrier 12. The focus magnet 152 is disposed on and connected to the side portion 112. The focus magnet 152 is used to drive the focus coil 151 and the focus carrier 12 to move relative to the side portion 112 along the first direction Z. The focus anti-shake motor 01 may also include a driver chip 19. The driver chip 19 is connected to the focus carrier 12 and electrically connected to the focus coil 151. The driver chip 19 and the focus coil 151 are both disposed on the focus carrier 12, meaning that the driver chip 19 and the focus coil 151 do not move relative to each other, facilitating electrical connection between the focus coil 151 and the driver chip 19. In addition, in the first direction Z, the thicknesses of the focus coil 151 , the focus magnet 152 , and the focus carrier 12 overlap, thereby reducing the thickness of the focus anti-shake motor 01 .

[0082] In other embodiments, as shown in FIG11 , a focus coil 151 is disposed on and connected to the side portion 112. A focus magnet 152 is disposed on and connected to the focus carrier 12. The focus coil 151 is used to drive the focus magnet 152 and the focus carrier 12 to move relative to the side portion 112 along the first direction Z. Placing the focus coil 151 on the side portion 112 that does not need to move in the first direction Z facilitates powering the focus coil 151.

[0083] Continuing with FIG9 , the focus anti-shake motor 01 may further include a focus position sensor 20. The focus position sensor 20 is disposed within the focus coil 151 and is used to detect the relative position of the focus coil 151 and the focus magnet, that is, to detect the relative position of the focus carrier 12 and the focus base 11. The focus anti-shake motor 01 may further include an anti-shake position sensor 21. The anti-shake position sensor 21 is disposed within the second coil 1421 and is used to detect the relative position of the anti-shake coil and the second magnet, that is, to detect the relative position of the anti-shake carrier 13 and the focus carrier 12.

[0084] Continuing with FIG9 , the focus and anti-shake motor 01 may further include at least one second moving member 22, located on the side of the side portion 112 facing the focus carrier 12. The second moving member 22 is disposed between the focus carrier 12 and the side portion 112. The second moving member 22 disposed between the focus carrier 12 and the side portion 112 reduces frictional resistance during relative motion between the focus carrier 12 and the anti-shake carrier 13, thereby reducing the power required from the focus drive mechanism 15 and thereby reducing the size of the focus drive mechanism 15.

[0085] In addition, as shown in Figure 9, the side portion 112 is provided with a first slide groove 1121 and a second slide groove 1122 on the side facing the focus carrier 12. The at least one second moving part 22 may include a first slide post 221 and a second slide post 222. A portion of the first slide post 221 is arranged in the first slide groove 1121, and another portion of the first slide post 221 abuts against the focus carrier 12. A portion of the second slide post 222 is arranged in the second slide groove 1122, and another portion of the second slide post 222 abuts against the focus carrier 12. The first slide post 221 is accommodated by the first slide groove 1121 of the side portion 112, and the first slide post 221 abuts against the focus carrier 12, and then the first slide post 221 is limited by the first slide groove 1121 and the focus carrier 12 to prevent the first slide post 221 from being separated from between the focus carrier 12 and the side portion 112. Similarly, the second slide groove 1122 accommodates the second slide column 222, and the part of the second slide column 222 located outside the second slide groove 1122 also abuts against the focusing carrier 12, thereby limiting the second slide column 222 through the second slide groove 1122 and the focusing carrier 12, preventing the second slide column 222 from separating from between the focusing carrier 12 and the side 112.

[0086] On this basis, as further shown in FIG9 , a third slide groove 124 and a fourth slide groove 125 are defined on the side of the focus carrier 12 facing the side portion 112. The other portion of the first slide post 221 is located within the third slide groove 124, while the other portion of the second slide post 222 is located within the fourth slide groove 125. The third slide groove 124 defined on the focus carrier 12 further constrains the first slide post 221. Similarly, the fourth slide groove 125 defined on the focus carrier 12 further constrains the second slide post 222.

[0087] Continuing with FIG9 , the third chute 124 is a V-shaped groove. That is, in a plane parallel to the depth of the third chute 124, the side walls of the third chute 124 form a V-shape. The fourth chute 125 is a U-shaped groove. That is, in a plane parallel to the depth of the fourth chute 125, the side walls of the fourth chute 125 form a U-shape. A gap exists between the second slide post 222 and the groove wall of the fourth chute 125 facing away from or toward the third chute 124. The third chute 124 is a V-shaped groove, and its width decreases significantly along its depth. At this point, the other portion of the first slide post 221 is positioned within the V-shaped groove, ensuring that the first slide post 221 abuts against the groove wall, thereby ensuring that the focus carrier 12 moves relative to the focus base 11 along the direction of the V-shaped groove. Furthermore, the fourth chute 125 is a U-shaped groove, and its width decreases minimally along its depth. There is a gap between the second slide column 222 and the groove wall of the fourth groove 125 away from or toward the third groove 124, providing installation margin, thereby ensuring that when the focusing carrier 12 and the side portion 112 are installed, the other part of the second slide column 222 can be installed in the fourth groove 125.

[0088] Of course, it is understandable that one of the first sliding groove 1121 and the second sliding groove 1122 can also be a V-shaped groove, and the other can be a U-shaped groove.

[0089] In the embodiment shown in FIG9 , the second moving member 22 is taken as a sliding column. In other embodiments of the present application, the second moving member 22 may also be a ball.

[0090] In order to further improve the appearance ID of the camera module 200 and enable the lens 03 to be centered in the XY plane when powered off, as shown in Figure 9, the focus anti-shake motor 01 may also include at least one elastic member 23, one end of the elastic member 23 is connected to the focus carrier 12, and the other end is connected to the anti-shake carrier 13, and the elastic deformation direction of the elastic member 23 is perpendicular to the first direction Z. When the anti-shake drive mechanism 14 drives the anti-shake carrier 13 to move on a plane perpendicular to the first direction Z, the elastic member 23 will undergo elastic deformation. When the anti-shake drive mechanism 14 stops working, the force generated by the elastic deformation of the elastic member 23 pushes the anti-shake carrier 13 to reset, thereby achieving the centering of the anti-shake carrier 13. In addition, the elastic member 23 can provide anti-torsion force to the anti-shake carrier 13, hindering the rotation of the anti-shake carrier 13.

[0091] For example, as shown in Figure 9 , the focus anti-shake motor 01 may include four elastic members 23, and the anti-shake carrier 13 may include four corners 136. The four elastic members 23 are disposed one-to-one on the four corners 136. The four elastic members 23, disposed one-to-one on the four corners 136, and their elastic deformation, increase the force pushing the anti-shake carrier 13 back to its original position, ensuring the centering of the anti-shake carrier 13. Furthermore, the four elastic members 23 increase the anti-torsion strength of the anti-shake carrier 13, further hindering its rotation.

[0092] Of course, it is understandable that in other embodiments of the present application, the number of elastic members 23 may also be other numbers, such as 1, 2, 3, etc.

[0093] As shown in Figure 13, the anti-shake carrier 13 may include a first plastic component 133 and a boss 137. The boss 137 is disposed on the side of the first plastic component 133 facing away from the focus base 11 and is connected to the first plastic component 133. The elastic component 23 may include a first connecting portion 231, an elastic portion 232, and a second connecting portion 233. The first connecting portion 231 is connected to the focus carrier 12. The elastic portion 232 is connected to the first connecting portion 231. The second connecting portion 233 is connected to the elastic portion 232, and a mounting hole 2331 is defined in the second connecting portion 233. One end of the boss 137 extends into the mounting hole 2331 and abuts or connects with the second connecting portion 233. The boss 137 cooperates with the second connecting portion 233 to secure the second connecting portion 233 relative to the anti-shake carrier 13. When the focus carrier 12 and the anti-shake carrier 13 move relative to each other, the first connecting portion 231 and the second connecting portion 233 are driven to move relative to each other. At this point, the relaxed elastic portion 232 deforms. When the electronic device stops recording, the anti-shake drive mechanism 14 stops providing driving force. The elastic portion 232 then pushes the second connecting portion 233 back into place, which in turn drives the anti-shake carrier 13 back into place, ultimately centering the anti-shake carrier 13.

[0094] Continuing with FIG9 , the focus anti-shake motor 01 may include a circuit board 24. The circuit board 24 is disposed on the focus base 11, and the circuit board 24 is connected to the focus base 11. As shown in FIG12 , the focus carrier 12 may include a second plastic part 126 and a metal bracket 127. As shown in FIG13 , the metal bracket 127 is embedded in the second plastic part 126, and one end of the metal bracket 127 facing away from the focus base 11 protrudes from the second plastic part 126. One end of the metal bracket 127 facing the focus base 11 is electrically connected to the circuit board 24. The elastic member 23 includes at least one of a conductive spring and a conductive suspension wire. The elastic member 23 is electrically connected to one end of the metal bracket 127 facing away from the focus base 11, and the elastic member 23 is used to be electrically connected to the variable aperture 04 (as shown in FIG3A ). The elastic member 23 connects the variable aperture 04 to the metal bracket 127. By supplying power to the circuit board 24, the current is transmitted to the metal bracket 127, which is electrically connected to the circuit board 24. This current is then transmitted through the elastic member 23, thereby powering the variable aperture 04. When the focus and anti-shake motor 01 is used in a camera module, the variable aperture 04 is mounted on the anti-shake carrier 13. When the anti-shake carrier 13 drives the variable aperture 04 to move relative to the focus carrier 12, the elastic member 23 deforms itself, preventing disconnection between the metal bracket 127 and the elastic member 23, and between the elastic member 23 and the variable aperture 04, thereby ensuring stable power supply. Furthermore, the metal bracket 127 increases the rigidity of the focus carrier 12, ensuring its mechanical strength.

[0095] Of course, the aforementioned driver chip 19, first coil 1411, second coil 1421, anti-shake position sensor 21, focus coil 151, and focus position sensor 20 can all be electrically connected to the metal bracket 127. By supplying power to the circuit board 24, current is transmitted through the metal bracket 127 to the driver chip 19, and then transmitted through the driver chip 19 to the first coil 1411, second coil 1421, focus coil 151, anti-shake position sensor 21, or focus position sensor 20. Alternatively, the metal bracket 127 can directly transmit current to the first coil 1411, second coil 1421, focus coil 151, anti-shake position sensor 21, or focus position sensor 20, thereby providing power to the first coil 1411, second coil 1421, focus coil 151, anti-shake position sensor 21, and focus position sensor 20.

[0096] As shown in Figure 14, the circuit board 24 may include a first flexible board 241 and a second flexible board 242. Continuing with Figure 9, the first flexible board 241 is positioned on one side of the focus carrier 12 and connected to the metal bracket 127 (shown in Figure 13). Along the first direction Z, the second flexible board 242 is positioned between the focus base 11 and the focus carrier 12. The first end of the second flexible board 242 is connected to the first flexible board 241, and the second end of the second flexible board 242 is connected to the focus base 11. When the focus carrier 12 moves relative to the focus base 11, the elastic deformation of the second flexible board 242 causes the first end of the second flexible board 242 to move with the focus carrier 12, while the second end remains connected to the focus base 11. This ensures that during the movement of the focus carrier 12, current is supplied to the second end of the second flexible board 242, transmitting current through the first flexible board 241 to the metal bracket 127 and the elastic member 23, thereby powering the variable aperture 04.

[0097] It is understood that the first flexible board 241 and the second flexible board 242 can be an integral flexible circuit board 24. Of course, the first flexible board 241 and the second flexible board 242 can also both be flexible circuit boards 24, and the two flexible circuit boards 24 can be connected.

[0098] Continuing with FIG14 , the second flexible plate 242 is L-shaped or U-shaped. In this case, while the distance between the two ends of the second flexible plate 242 is the same, the L-shaped or U-shaped structure is longer, thereby providing better deformation capability. This ensures that when the focus carrier 12 and the focus base 11 move, the force required to deform the second flexible plate 242 is smaller, thereby reducing the maximum driving force required by the focus drive mechanism 15 and reducing the size of the focus drive mechanism 15.

[0099] 14 , the second flexible plate 242 may include a first portion 2421 and a second portion 2422 . The first portion 2421 is L-shaped, and the second portion 2422 is U-shaped. The first portion 2421 and the second portion 2422 are an integrated structure.

[0100] In other embodiments of the present application, the second flexible board 242 may also include only the first portion 2421 . Alternatively, the second flexible board 242 may also include only the second portion 2422 .

[0101] Continuing with FIG9 , the focus drive mechanism 15 is connected to the first side wall 128 of the focus carrier 12. The first flexible plate 241 is connected to the portion of the second side wall 129 of the focus carrier 12 that faces the first side wall 128. The first side wall 128 and the second side wall 129 are adjacent to each other. The focus drive mechanism 15 and the first flexible plate 241 are located on different side walls of the focus carrier 12, respectively, for ease of installation. Furthermore, when the focus drive mechanism 15 drives the focus carrier 12 to move relative to the focus base 11, the force acting on the focus carrier 12 is primarily concentrated on the first side wall 128 where the focus carrier 12 connects to the focus drive mechanism 15. The first flexible plate 241 is connected to the portion of the second side wall 129 that faces the first side wall 128. In other words, the reaction force exerted by the first and second flexible plates 241 and 242 on the focus carrier 12 is applied close to the position where the focus drive mechanism 15 exerts its force on the focus carrier 12, thereby reducing the tipping arm and moment of the reaction force.

[0102] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
