Description

Technical Field

[0001] This invention relates to the field of camera technology, and more particularly to a focusing and image stabilization motor, a camera module, and an electronic device. Background Technology

[0002] With the popularization and development of electronic devices, taking photos and videos has become one of the most commonly used functions. Electronic devices with optical image stabilization and autofocus are increasingly favored by users.

[0003] As users' demands for photography and videography increase, the load on the image stabilization drive mechanism becomes heavier. Its own weight can cause the lens to shift in the stabilization travel direction, affecting the industrial design (ID). Therefore, the image stabilization drive mechanism needs to be designed with a larger electromagnetic driving force, resulting in a larger overall size. Summary of the Invention

[0004] The purpose of this application is to provide a focusing and image stabilization motor, a camera module, and an electronic device, which reduces the driving force required by the image stabilization drive mechanism and reduces the overall size of the image stabilization drive mechanism and the focusing and image stabilization motor.

[0005] A first aspect of this application provides a focusing and image stabilization motor, including a focusing base, a focusing carrier, an image stabilization carrier, an image stabilization drive mechanism, and a focusing drive mechanism. The focusing carrier is disposed on the focusing base and movably connected to the focusing base along a first direction, and the focusing carrier has a receiving space. The image stabilization carrier is disposed within the receiving space and movably connected to the focusing carrier in a plane perpendicular to the first direction. The image stabilization drive mechanism is disposed within the receiving space and connected to both the focusing carrier and the image stabilization carrier, and is used to drive the image stabilization carrier to move relative to the focusing carrier along a direction perpendicular to the first direction. The focusing drive mechanism is connected to both the focusing base and the focusing carrier, and is used to drive the focusing carrier to move relative to the focusing base along the first direction. The first direction is the stacking direction of the focusing base, the focusing carrier, and the image stabilization carrier.

[0006] In related technologies, the focusing carrier is located inside the image stabilization carrier, and the image stabilization drive mechanism drives both the image stabilization carrier and the focusing carrier to move together. In this case, the components that need to move in the image stabilization stroke include the image stabilization carrier, the focusing carrier, the lens mounted on the focusing carrier, and the variable aperture, resulting in a significant total weight. To prevent the lens from shifting in the image stabilization stroke due to its own weight, thus affecting the industrial design, the image stabilization drive mechanism needs to provide greater driving force during the image stabilization process to overcome forces such as gravity, thereby achieving image stabilization. Therefore, the required size of the image stabilization drive mechanism is relatively large, leading to a larger overall size for products incorporating the image stabilization drive mechanism.

[0007] In this embodiment, the image stabilization carrier is disposed within the accommodating space of the focusing carrier, and the focusing carrier does not move in a direction perpendicular to the first direction. That is, during image stabilization, the image stabilization drive mechanism does not need to drive the focusing carrier, the maximum driving force required by the image stabilization drive mechanism is smaller, the required size of the image stabilization drive mechanism is smaller, and the overall size of the product with the image stabilization drive mechanism is smaller. Furthermore, in some solutions, a portion of the image stabilization drive mechanism is fixed to the focusing base. When the focusing drive mechanism drives the focusing carrier to move relative to the focusing base along the first direction, the portion of the image stabilization drive mechanism connected to the focusing carrier moves accordingly, resulting in eccentricity and affecting image stabilization accuracy. In this application, the image stabilization drive mechanism is connected to both the focusing carrier and the image stabilization carrier. When the focusing drive mechanism drives the focusing carrier to move relative to the focusing base along the first direction, it causes the image stabilization carrier and the image stabilization drive mechanism to move together. That is, the image stabilization drive mechanism does not produce eccentric movement, thereby improving image stabilization accuracy.

[0008] In one optional embodiment, the image stabilization carrier is a frame structure, with two adjacent side frames forming a first side frame and a second side frame. The focusing and image stabilization motor includes two image stabilization drive mechanisms: a first image stabilization drive mechanism and a second image stabilization drive mechanism. The first image stabilization drive mechanism is connected to both the first side frame and the focusing carrier. The second image stabilization drive mechanism is connected to both the second side frame and the focusing carrier. The first and second image stabilization drive mechanisms are respectively connected to the two adjacent side frames of the image stabilization carrier, thereby driving the image stabilization carrier to move in different directions on a plane perpendicular to a first direction, thus achieving image stabilization displacement of the image stabilization carrier on that plane.

[0009] In one optional embodiment, the focusing and image stabilization motor further includes an intermediate sliding plate. The intermediate sliding plate is located on the side of the image stabilization carrier facing the focusing base, and the intermediate sliding plate and the image stabilization carrier are stacked within a receiving space. Along a second direction, the intermediate sliding plate is movably connected to the focusing carrier, and the image stabilization carrier abuts against the intermediate sliding plate. A first image stabilization drive mechanism is used to drive the image stabilization carrier and the intermediate sliding plate to move relative to the focusing carrier. Along a third direction, the image stabilization carrier is movably connected to the intermediate sliding plate, and a second image stabilization drive mechanism is used to drive the image stabilization 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 this case, in the first direction, the image stabilization carrier abuts against the intermediate sliding plate, and when the first image stabilization drive mechanism drives the image stabilization carrier to move along the second direction, it causes the intermediate sliding plate to move together relative to the focusing carrier. In the third direction, the image stabilization carrier is movably connected to the intermediate sliding plate, and the second image stabilization drive mechanism drives the image stabilization carrier to move relative to the intermediate sliding plate, and thus relative to the focusing carrier. This achieves image stabilization displacement of the image stabilization carrier in the planes of the second and third directions.

[0010] In one optional embodiment, the focusing carrier includes an image stabilization base and a top cover. The image stabilization base is disposed on the focusing base. The top cover is located on the side of the image stabilization carrier opposite to the image stabilization base. The top cover is disposed on the image stabilization base and connected to the image stabilization base. The image stabilization base and the top cover enclose a receiving space. The image stabilization drive mechanism includes an upper image stabilization drive mechanism and a lower image stabilization drive mechanism. The upper image stabilization drive mechanism is located between the top cover and the image stabilization carrier and is connected to both the top cover and the image stabilization carrier. The lower image stabilization drive mechanism is located between the image stabilization base and the image stabilization carrier and is connected to both the image stabilization base and the image stabilization carrier. Both the image stabilization carrier and the image stabilization drive mechanism are disposed within the receiving space enclosed by the image stabilization base and the top cover. In a first direction, the top cover can limit the movement of the image stabilization carrier and the image stabilization drive mechanism, preventing the image stabilization carrier from leaving the receiving space. The upper and lower image stabilization drive mechanisms are respectively disposed on both sides of the image stabilization carrier, which can increase the driving force of the image stabilization drive mechanism on the image stabilization carrier.

[0011] In one optional embodiment, the upper stabilization drive mechanism includes a first coil and a first magnet. The first coil is connected to the side of the upper cover facing the stabilization carrier, and the first magnet is connected to the side of the stabilization carrier facing the upper cover. The lower stabilization drive mechanism includes a second coil and a second magnet. The second coil is connected to the side of the stabilization base facing the stabilization carrier, and the second magnet is connected to the side of the stabilization carrier facing the stabilization base. The first coil and the second coil are located on opposite sides of the first magnet and the second magnet, respectively. By fully utilizing the magnetic fields of the first magnet and the second magnet on both sides in the first direction, the driving force of the upper and lower stabilization drive mechanisms is increased, thereby reducing the size of the stabilization drive mechanism. 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 stabilization carrier, the two sets of forces can weaken each other, reducing the tendency of the stabilization carrier to move in the first direction. Furthermore, the first coil, which requires power to operate, is connected to the top cover. When the first magnet drives the anti-shake carrier to perform anti-shake movement, the top cover does not need to move with the anti-shake carrier, meaning the first coil does not need to move, facilitating power supply. Similarly, the second coil, which also requires power to operate, is connected to the anti-shake base. When the second magnet drives the anti-shake carrier to perform anti-shake movement, the anti-shake base also does not need to move with the anti-shake carrier, meaning the second coil also does not need to move, facilitating power supply.

[0012] In one optional embodiment, a first groove is formed on the surface of the image stabilization carrier facing the top cover. A first magnet is located within the first groove. A second groove is formed on the surface of the image stabilization carrier facing the image stabilization base. A second magnet is located within the second groove. The first groove accommodates the first magnet, thereby limiting the first magnet and preventing it from detaching from the image stabilization carrier. The second groove accommodates the second magnet, thereby limiting the second magnet and preventing the first magnet from detaching from the image stabilization carrier. Furthermore, by placing the first magnet within the first groove and the second magnet within the second groove, the total thickness of the first magnet, the image stabilization carrier, and the second magnet in the first direction can be reduced, thereby reducing the size of the focusing and image stabilization motor.

[0013] In one optional embodiment, the image stabilization carrier includes a first plastic component and a first magnetically conductive sheet. The first magnetically conductive sheet is embedded within the first plastic component. A portion of the first magnetically conductive sheet forms the bottom of a first groove and a second groove. Under magnetic force, the first magnet and the second magnet exert a mutual force on the first magnetically conductive sheet, further ensuring the connection stability between the first magnet, the second magnet, and the image stabilization carrier, and reducing the occurrence of the image stabilization drive mechanism detaching from the image stabilization carrier.

[0014] In one optional embodiment, the first magnet and the second magnet are connected as a single structural component. A through-hole is formed on the anti-shake carrier. The single structural component is embedded within the through-hole. The first magnet and the second magnet being a single structural component facilitates the installation of the anti-shake drive mechanism and the anti-shake carrier.

[0015] In one optional embodiment, the focusing and image stabilization motor further includes a first moving member. The first moving member is located on the side of the image stabilization carrier facing the image stabilization base and is disposed between the image stabilization base and the image stabilization carrier. In a plane perpendicular to the first direction, the image stabilization carrier is movably connected to the image stabilization base via the first moving member. Exemplarily, the first moving member can be a ball bearing, a superslipper, or a sliding column. By using the first moving member disposed between the focusing carrier and the image stabilization carrier, the resistance during relative movement between the focusing carrier and the image stabilization carrier is reduced, thereby reducing the power required from the image stabilization drive mechanism and thus reducing the size of the image stabilization drive mechanism.

[0016] In one optional embodiment, the image stabilization carrier includes four corners. The focusing and image stabilization motor includes a plurality of first moving parts, and the plurality of first moving parts are disposed between at least three corners of the image stabilization carrier and the image stabilization base. The first moving parts distributed at the three corners of the image stabilization carrier provide support for the image stabilization carrier, ensuring that the image stabilization carrier does not directly contact the image stabilization base, thereby reducing the friction between the image stabilization base and the image stabilization carrier.

[0017] In one optional embodiment, the focusing and image stabilization motor further includes a second magnetic sheet. Along a first direction, the second magnetic sheet and the image stabilization carrier are stacked on the image stabilization base. The second magnetic sheet is connected to the image stabilization base. The second magnetic sheet is used to attract a second magnet. At this time, the second magnetic sheet is connected to the image stabilization base, and the second magnet is connected to the image stabilization carrier. When there is an attraction force between the second magnet and the second magnetic sheet, the image stabilization carrier and the image stabilization base exert a force that brings them closer together, thereby pressing down on the first moving member disposed between the focusing carrier and the image stabilization carrier, preventing the first moving member from detaching from the focusing carrier and the image stabilization carrier.

[0018] In one optional embodiment, the focusing base includes a bottom and a side portion connected together, and the focusing drive mechanism includes a focusing coil and a focusing magnet. The focusing coil is disposed on and connected to the focusing carrier. The focusing magnet is disposed on and connected to the side portion. Along a first direction, the focusing magnet drives the focusing coil and the focusing carrier to move relative to the side portion. The focusing stabilization motor also includes a drive chip. The drive chip is connected to the focusing carrier and electrically connected to the focusing coil. Both the drive chip and the focusing coil are disposed on the focusing carrier, meaning that the drive chip and the focusing coil do not move relative to each other, facilitating the electrical connection between the focusing coil and the drive chip. Furthermore, in the first direction, the thicknesses of the focusing coil, the focusing magnet, and the focusing carrier overlap, thereby reducing the thickness of the focusing stabilization motor.

[0019] In another alternative embodiment, the focusing base includes a connected bottom and a side portion, and the focusing drive mechanism includes a focusing coil and a focusing magnet. The focusing coil is disposed on and connected to the side portion. The focusing magnet is disposed on and connected to the focusing carrier. Along a first direction, the focusing coil drives the focusing magnet and the focusing carrier to move relative to the side portion. Disposing the focusing coil on the side portion, where movement in the first direction is not required, facilitates power supply to the focusing coil.

[0020] In one optional embodiment, the focusing and image stabilization motor further includes at least one second moving member located on the side of the focusing carrier facing the focusing carrier and disposed between the focusing carrier and the side. By using the second moving member disposed between the focusing carrier and the side, the frictional resistance during relative movement between the focusing carrier and the image stabilization carrier is reduced, thereby reducing the power required from the focusing drive mechanism and consequently reducing the size of the focusing drive mechanism.

[0021] In one optional embodiment, a first groove and a second groove are formed on the side of the focusing carrier facing the side portion. At least one second moving member includes a first sliding post and a second sliding post. A portion of the first sliding post is disposed within the first groove, and another portion of the first sliding post abuts against the focusing carrier. A portion of the second sliding post is disposed within the second groove, and another portion of the second sliding post abuts against the focusing carrier. The first sliding post is accommodated by the first groove on the side portion, and the first sliding post abuts against the focusing carrier, thereby limiting the first sliding post by the first groove and the focusing carrier, preventing the first sliding post from disengaging from the focusing carrier and the side portion. Similarly, the second groove accommodates the second sliding post, and the portion of the second sliding post outside the second groove also abuts against the focusing carrier, thereby limiting the second sliding post by the second groove and the focusing carrier, preventing the second sliding post from disengaging from the focusing carrier and the side portion.

[0022] In one optional embodiment, a third and a fourth slide groove are formed on the side of the focusing carrier facing the side. A portion of the first slide post is located within the third slide groove, and a portion of the second slide post is located within the fourth slide groove. The third slide groove on the focusing carrier further limits the movement of the first slide post. Similarly, the fourth slide groove on the focusing carrier further limits the movement of the second slide post.

[0023] In one optional embodiment, the third slide groove is V-shaped, and the fourth slide groove is U-shaped. There is a gap between the second sliding post and the wall of the fourth slide groove, either facing away from or towards the third slide groove. The third slide groove is V-shaped, and its width decreases significantly with depth. In this case, the other part of the first sliding post is positioned within the V-shaped groove, ensuring that the first sliding post abuts against the 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. Furthermore, the fourth slide groove is U-shaped, and its width decreases less with depth. There is a gap between the second sliding post and the wall of the fourth slide groove, either facing away from or towards the third slide groove, providing installation allowance, thereby ensuring that when the focusing carrier is mounted to the side, the other part of the second sliding post can be installed in the fourth slide groove.

[0024] In one optional embodiment, the focusing and image stabilization motor further includes at least one elastic element. One end of the elastic element is connected to the focusing carrier, and the other end is connected to the image stabilization carrier. The elastic deformation direction of the elastic element is perpendicular to a first direction. When the image stabilization drive mechanism drives the image stabilization carrier to move in a plane perpendicular to the first direction, the elastic element undergoes elastic deformation. When the image stabilization drive mechanism stops working, the force generated by the elastic deformation of the elastic element pushes the image stabilization carrier to reset, thereby achieving centering of the image stabilization carrier. In addition, the elastic element can provide anti-torsional force to the image stabilization carrier, hindering the rotation of the image stabilization carrier.

[0025] In one optional embodiment, the focusing and image stabilization motor includes four elastic elements, and the image stabilization carrier includes four corner portions, with the four elastic elements correspondingly disposed on the four corner portions. By having four elastic elements correspondingly disposed on the four corner portions, the elastic deformation of these four elastic elements increases the force pushing the image stabilization carrier to return to its original position, ensuring the centering of the image stabilization carrier. Furthermore, the four elastic elements increase the torsional strength of the image stabilization carrier, further hindering its rotation.

[0026] In one optional embodiment, the image stabilization carrier includes a first plastic part and a protrusion. The protrusion is disposed on the side of the first plastic part opposite to the focusing base and is connected to the first plastic part. The elastic member includes a first connecting portion, an elastic portion, and a second connecting portion. The first connecting portion is connected to the focusing carrier. The elastic portion is connected to the first connecting portion. The second connecting portion is connected to the elastic portion and has a mounting hole. One end of the protrusion extends into the mounting hole and abuts against or connects with the second connecting portion. The relative fixation of the second connecting portion and the image stabilization carrier is achieved through the cooperation of the protrusion and the second connecting portion. When the focusing carrier and the image stabilization carrier move relative to each other, the first connecting portion and the second connecting portion move relative to each other. At this time, the elastic portion deforms. When the image stabilization drive mechanism stops working, the elastic portion pushes the second connecting portion to reset, thereby driving the image stabilization carrier to reset, thereby achieving the centering of the image stabilization carrier.

[0027] In one optional embodiment, the focusing carrier includes a second plastic component and a metal bracket. The metal bracket is embedded within the second plastic component, with one end of the metal bracket protruding from the second plastic component away from the focusing base. The focusing and image stabilization motor includes a circuit board and an elastic element. The circuit board is disposed on and connected to the focusing base. The end of the metal bracket facing the focusing base is electrically connected to the circuit board. The elastic element includes at least one of a conductive spring and a conductive suspension wire. The elastic element is electrically connected to the end of the metal bracket away from the focusing base, and the elastic element is also used for electrical connection with a variable aperture.

[0028] The elastic element connects the variable aperture and the metal bracket, supplying power to the circuit board. Current is then transmitted to the metal bracket, which is electrically connected to the circuit board, and through the elastic element, power the variable aperture. When the focus stabilization motor is used in a camera module, the variable aperture is mounted on the stabilization carrier. As the stabilization carrier moves the variable aperture relative to the focus carrier, the elastic element deforms to prevent the connection between the metal bracket and the elastic element, and between the elastic element and the variable aperture, ensuring stable power supply. Additionally, the metal bracket increases the rigidity of the focus carrier, ensuring its mechanical strength.

[0029] In one optional embodiment, the circuit board includes a first flexible plate and a second flexible plate. The first flexible plate is disposed on one side of the focusing carrier and connected to a metal support. Along a first direction, the second flexible plate is disposed between the focusing base and the focusing carrier, with a first end connected to the first flexible plate and a second end connected to the focusing base. When the focusing carrier moves relative to the focusing base, the elastic deformation of the second flexible plate causes the first end of the second flexible plate to move with the focusing carrier, while the second end remains connected to the focusing base. This ensures that during the movement of the focusing carrier, power is supplied to the second end of the second flexible plate, and the current is transmitted through the first flexible plate to the metal support and elastic element, thereby powering the variable aperture.

[0030] It is understood that the first flexible board and the second flexible board can be a single flexible circuit board. Of course, the first flexible board and the second flexible board can also be flexible circuit boards, and the two flexible circuit boards can be connected.

[0031] In one optional embodiment, the second flexible plate is L-shaped or U-shaped. In this case, with the distance between the two ends of the second flexible plate being the same, the L-shaped or U-shaped structure has a longer length, thus having better deformation capability. This ensures that when the focusing carrier and focusing base move, the force required for the second flexible plate to deform accordingly is smaller, thereby reducing the maximum driving force required by the focusing drive mechanism and reducing the volume of the focusing drive mechanism.

[0032] In one optional embodiment, the focusing drive mechanism is connected to the first sidewall of the focusing carrier. A first flexible plate is connected to the portion of the second sidewall of the focusing carrier facing the first sidewall. The first and second sidewalls are adjacent to each other. The focusing drive mechanism and the first flexible plate are located on different sidewalls of the focusing carrier, facilitating installation. Furthermore, when the focusing drive mechanism drives the focusing carrier to move relative to the focusing base, its force is mainly concentrated on the first sidewall connected to the focusing drive mechanism. The first flexible plate is connected to the portion of the second sidewall facing the first sidewall. That is, the reaction force exerted by the first and second flexible plates on the focusing carrier is located close to the force exerted by the focusing drive mechanism on the focusing carrier, thereby reducing the tilting arm and torque of the reaction force.

[0033] A second aspect of this application provides a camera module including the aforementioned focus-stabilization motor and variable aperture. The variable aperture is connected to the image stabilization carrier. The camera module described above has the same technical effects as the focus-stabilization motor provided in the foregoing embodiments, and will not be repeated here.

[0034] A third aspect of this application provides an electronic device, including a housing and the aforementioned camera module. The camera module is disposed within the housing. The electronic device described above has the same technical effects as the camera module provided in the foregoing embodiments, and will not be repeated here. Attached Figure Description

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

[0057] This application provides an electronic device 100, such as... Figure 1 As shown, the electronic device 100 may include a camera module 200 and a housing 300. The camera module 200 is disposed within the housing 300, which protects the camera module 200. The camera module 200 may have a photo-taking function. The electronic device 100 may be a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR headset, virtual reality (VR) glasses, or VR headset, etc., that has a camera module 200. This application embodiment does not impose any special limitations on the specific form of the above-described electronic device 100.

[0058] The outer casing 300 has a light-transmitting hole 301 for exposing part of the camera module 200. The camera module 200 is used to collect ambient light entering the electronic device 100 through the light-transmitting hole 301.

[0059] The structure of the camera module 200 is illustrated below with examples. In some embodiments of this application, such as... Figure 2 As shown, the camera module 200 may include a housing 02. The housing 02 has a cavity (not shown in the figure). The housing 02 also has an opening 021 communicating with the cavity. The housing 02 is used to protect the internal components.

[0060] like Figure 3AAs shown, the camera module 200 may include a lens 03. The lens 03 may include one or more optical lenses. These optical lenses can be convex or concave lenses, allowing the lens 03 with these optical lenses to utilize the refraction principle of the optical lenses to converge the light from the subject onto the focal plane of the camera module 200 for imaging. Multiple optical lenses are arranged sequentially along the optical axis OO of the lens 03.

[0061] Continue as Figure 3A As shown, the camera module 200 may also include a variable aperture 04. The variable aperture 04 is located on the light-incident side of the lens 03. An 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] Furthermore, continue as Figure 3A As shown, the camera module 200 may also include a focus and image stabilization motor 01. For ease of explanation, the direction parallel to the optical axis OO is designated as the Z-axis, and two mutually perpendicular directions, both perpendicular to the optical axis OO, are designated as the X-axis and Y-axis, both located in the XY plane. Hereinafter, the Z-axis direction will be described as the first direction, the X-axis direction as the second direction, and the Y-axis direction as the third direction. Figure 3B (along Figure 2 As shown in the cross-sectional view obtained along the P1-P2 direction, the variable aperture 04 and lens 03 are respectively connected to the focus and image stabilization motor 01 (as shown in the cross-sectional view obtained along the P1-P2 direction). Figure 3A (As shown) connection. At this time, the focusing and image stabilization motor 01 can drive the lens 03 and the variable aperture 04 to move along the first direction Z to achieve autofocus (AF). In addition, the focusing and image stabilization 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 related technologies, such as Figure 4 As shown, the camera module houses the focus actuator 31 inside the image stabilization actuator 32. This means the image stabilization drive mechanism (not shown) needs to drag the image stabilization actuator 32 and the focus actuator 31 together. At this time, the components that need to move in the direction perpendicular to the first direction Z include the image stabilization actuator 32, the focus actuator 31, the lens 03 mounted on the focus actuator 31, and the variable aperture 04, resulting in a significant total weight. The image stabilization drive mechanism requires a large driving force. Furthermore, to prevent the lens 03 from shifting in the direction perpendicular to the first direction Z due to its own weight, thus affecting the industrial design, additional components (such as springs or magnetic components, not shown) are needed to provide a counterforce that can counteract gravity (e.g., ...). Figure 4(In the Y direction). During image stabilization, the stabilization motor needs to provide greater driving force to overcome forces such as gravity, spring reaction force, or magnetic attraction force, thereby achieving image stabilization. Therefore, the required size of the stabilization drive mechanism is relatively large, resulting in a larger overall size of the camera module with the stabilization drive mechanism.

[0064] To address the aforementioned problems, in some embodiments of this application, such as... Figure 5 As shown, the aforementioned focusing and image stabilization motor 01 may include a focusing base 11, a focusing carrier 12, an image stabilization carrier 13, and an image stabilization drive mechanism 14. The focusing carrier 12 may be disposed on the focusing base 11 and movably connected to the focusing base 11 along a first direction Z. The focusing carrier 12 has a receiving space 121. The image stabilization carrier 13 is disposed within the receiving space 121 and movably connected to the focusing carrier 12 in an XY plane perpendicular to the first direction Z. The first direction Z is the stacking direction of the focusing base 11, the focusing carrier 12, and the image stabilization carrier 13. The image stabilization drive mechanism 14 is disposed within the receiving space 121 and connected to both the focusing carrier 12 and the image stabilization carrier 13. The image stabilization drive mechanism 14 drives the image stabilization carrier 13 to move relative to the focusing carrier 12 along a direction perpendicular to the first direction Z (i.e., the direction in the XY plane) to achieve optical image stabilization.

[0065] At this time, the focusing carrier 12 does not need to move relative to the focusing base 11 in the XY plane. In other words, the image stabilization drive mechanism 14 does not need to drive the focusing carrier 12. That is, during optical image stabilization, the focusing carrier 12 does not need to move relative to the focusing base 11. The total force required to drive the image stabilization drive mechanism 14 is relatively small, and the maximum driving force required is also relatively small. Furthermore, the gravity of the focusing carrier 12 does not participate in the image stabilization travel offset, reducing the total gravity of components that may be offset in the XY plane. Therefore, the additional counterforce required to counteract this gravity (such as springs or magnetic components) can be smaller. During image stabilization, the maximum driving force required by the image stabilization motor is smaller, resulting in a smaller required motor size. Consequently, the overall size of the lens module 03 with the image stabilization drive mechanism 14 is relatively large.

[0066] In some designs, a portion of the image stabilization drive mechanism 14 is fixed to the focusing base 11. When the focusing drive mechanism 15 drives the focusing carrier 12 to move relative to the focusing base 11 along the first direction Z, the portion of the image stabilization drive mechanism 14 connected to the focusing carrier 12 moves accordingly, resulting in eccentricity and affecting the image stabilization accuracy.

[0067] To solve the above problems, continue as follows Figure 5As shown, the aforementioned focusing and image stabilization motor 01 may include a focusing drive mechanism 15. The focusing drive mechanism 15 can be connected to both the focusing base 11 and the focusing carrier 12, and is used to drive the focusing carrier 12 to move relative to the focusing base 11 along a first direction Z to achieve autofocus. The image stabilization drive mechanism 14 is connected to both the focusing carrier 12 and the image stabilization carrier 13. When the focusing drive mechanism 15 drives the focusing carrier 12 to move relative to the focusing base 11 along the first direction Z, it will cause the image stabilization carrier 13 to move together with the image stabilization drive mechanism 14. That is, the image stabilization drive mechanism 14 will not produce eccentric movement, thereby improving image stabilization accuracy.

[0068] Furthermore, such as Figure 6 As shown, the image stabilization carrier 13 can be a frame structure, with two adjacent borders of the frame structure being a first border 131A and a second border 131B. Continuing as... Figure 5 As shown, the focusing and image stabilization motor 01 may include two image stabilization drive mechanisms 14, namely a first image stabilization drive mechanism 14A and a second image stabilization drive mechanism 14B. The first image stabilization drive mechanism 14A is connected to the first frame 131A (as shown in the image). Figure 6 (As shown) and the focusing carrier 12 are connected. The second image stabilization drive mechanism 14B is connected to the second frame 131B (as shown) Figure 6 (As shown) and the focusing carrier 12 are connected. The first image stabilization drive mechanism 14A and the second image stabilization drive mechanism 14B are respectively connected to the two adjacent frames of the image stabilization carrier 13, thereby driving the image stabilization carrier 13 to move in different directions on the XY plane perpendicular to the first direction Z, thereby realizing the image stabilization displacement of the image stabilization carrier 13 on this plane.

[0069] Continue as Figure 5As shown, the focusing carrier 12 may include an image stabilization base 122 and an upper cover 123. The image stabilization base 122 is disposed on the focusing base 11. The upper cover 123 is located on the side of the image stabilization carrier 13 opposite to the image stabilization base 122. The upper cover 123 covers the image stabilization base 122 and is connected to the image stabilization base 122. The image stabilization base 122 and the upper cover 123 enclose a receiving space 121. The image stabilization drive mechanism 14 may include an upper image stabilization drive mechanism 141 and a lower image stabilization drive mechanism 142. The upper image stabilization drive mechanism 141 is located between the upper cover 123 and the image stabilization carrier 13. The upper image stabilization drive mechanism 141 is connected to both the upper cover 123 and the image stabilization carrier 13. The lower image stabilization drive mechanism 142 is located between the image stabilization base 122 and the image stabilization carrier 13. The lower image stabilization drive mechanism 142 is connected to both the image stabilization base 122 and the image stabilization carrier 13. Both the stabilization carrier 13 and the stabilization drive mechanism 14 are disposed in the receiving space 121 enclosed by the stabilization base 122 and the upper cover 123, in the first direction Z. By controlling the driving directions of the upper stabilization drive mechanism 141 and the lower stabilization drive mechanism 142, the driving directions of the upper stabilization drive mechanism 141 and the lower stabilization drive mechanism 142 are made to have the same directional component, thereby increasing the driving force of the stabilization drive mechanism 14 on the stabilization carrier 13.

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

[0071] In addition, continue as Figure 5As shown, the upper image stabilization 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 image stabilization carrier 13, and the first magnet 1412 is connected to the side of the image stabilization carrier 13 facing the upper cover 123. The lower image stabilization drive mechanism 142 includes a second coil 1421 and a second magnet 1422. The second coil 1421 is connected to the side of the image stabilization base 122 facing the image stabilization carrier 13, and the second magnet 1422 is connected to the side of the image stabilization carrier 13 facing the image stabilization 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. Both sides of the first magnet 1412 generate a magnetic field. At this time, the first coil 1411 and the second coil 1421 are located within the magnetic fields on either side of the first magnet 1412, and thus both coils can generate a driving force using the magnetic field of the first magnet 1412. Similarly, both sides of the second magnet 1422 generate magnetic fields. Therefore, the first coil 1411 and the second coil 1421 are located within the magnetic fields on either side of the second magnet 1422, and thus both coils can generate a driving force using the magnetic field of the second magnet 1422. This increases the driving force of the upper anti-shake drive mechanism 141 and the lower anti-shake drive mechanism 142, thereby reducing the size of the anti-shake drive mechanism 14.

[0072] Furthermore, along the first direction Z, the first coil 1411 and the first magnet 1412 will also generate forces that move closer or further apart. Similarly, the second coil 1421 and the second magnet 1422 will also generate forces that move closer or further apart. 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. Thus, after both the first magnet 1412 and the second magnet 1422 are connected to the image stabilization carrier 13, the two sets of forces can weaken each other, reducing the tendency of the image stabilization carrier 13 to move in the first direction Z, and preventing the focus accuracy from being affected by the movement of the image stabilization carrier 13 in the first direction Z. 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, meaning the first coil 1411 does not need to move, facilitating the supply of power to the first coil 1411. Similarly, the second coil 1421, which also 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, meaning the second coil 1421 also does not need to move, facilitating the supply of power to the second coil 1421.

[0073] In some embodiments, such as Figure 7 (along Figure 6 As shown in the cross-sectional view obtained along the N1-N2 direction, the anti-shake carrier 13 faces the upper cover 123 (as shown in the cross-sectional view obtained along the N1-N2 direction). Figure 5 A first groove 131 is formed on the surface of the image (as shown). A first magnet 1412 is located in the first groove 131. The image stabilization carrier 13 faces the image stabilization base 122 (as shown). Figure 5 A second groove 132 is formed on the surface of the image stabilization motor (as shown). 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 first magnet 1412 and preventing it from detaching from the image stabilization carrier 13. The second magnet 1422 is accommodated by the second groove 132, thereby limiting the second magnet 1422 and preventing it from detaching from the image stabilization carrier 13. In addition, by placing the first magnet 1412 in the first groove 131 and the second magnet 1422 in the second groove 132, the thickness of the focusing and image stabilization motor in the first direction Z can be reduced after the first magnet 1412, the image stabilization carrier 13, and the second magnet 1422 are assembled, thereby reducing the size of the focusing and image stabilization motor 01.

[0074] Continue as Figure 7 As shown, the image stabilization carrier 13 may include a first plastic part 133 and a first magnetic sheet 134. The first magnetic sheet 134 is embedded in the first plastic part 133. A portion of the first magnetic sheet 134 is the bottom 111 of the first groove 131 and the second groove 132. The first magnet 1412 and the second magnet 1422 have magnetic attraction with the first magnetic sheet 134, which further ensures the connection stability between the first magnet 1412 and the second magnet 1422 and the image stabilization carrier 13, and reduces the occurrence of the image stabilization drive mechanism 14 disengaging from the image stabilization carrier 13.

[0075] In other embodiments, such as Figure 8 (along Figure 6 As shown in the cross-sectional view along the N1-N2 direction, the first magnet 1412 and the second magnet 1422 are connected as a single structural component. A through hole 135 is provided on the anti-shake carrier 13. The single structural component is embedded within the through hole 135. The fact that the first magnet 1412 and the second magnet 1422 are a single structural component facilitates the installation of the anti-shake drive mechanism 14 and the anti-shake carrier 13.

[0076] continue Figure 9 As shown, the focus stabilization motor 01 may further include a first moving member 16. The first moving member 16 is located on the side of the stabilization carrier 13 facing the stabilization base 122. Figure 3BAs shown, the first moving member 16 is disposed between the image stabilization base 122 and the image stabilization carrier 13. In the XY plane perpendicular to the first direction Z, the image stabilization carrier 13 is movably connected to the image stabilization base 122 via the first moving member 16. Exemplarily, the first moving member 16 can be a ball bearing, a superslipper, or a sliding column. By disposing of the first moving member 16 between the focusing carrier 12 and the image stabilization carrier 13, the contact area between the focusing carrier 12 and the image stabilization carrier 13 can be reduced, thereby reducing the resistance during relative movement between the focusing carrier 12 and the image stabilization carrier 13, thus reducing the power required from the image stabilization drive mechanism 14, and consequently reducing the size of the image stabilization drive mechanism 14.

[0077] Continue as Figure 9 As shown, the image stabilization carrier 13 can be a frame structure with four sides and four corners 136 where adjacent sides intersect. The focusing and image stabilization motor 01 can include multiple first moving parts 16, and the multiple first moving parts 16 are disposed between at least three corners 136 of the image stabilization carrier 13 and the image stabilization base 122. The first moving parts 16 distributed at the three corners 136 of the image stabilization carrier 13 provide support for the image stabilization carrier 13, ensuring that the image stabilization carrier 13 does not directly contact the image stabilization base 122, thereby reducing the friction between the image stabilization base 122 and the image stabilization carrier 13.

[0078] The above are as follows Figure 9 In the embodiment shown, a first moving member 16 is provided between each of the four corners 136 of the anti-shake carrier 13 and the anti-shake base 122.

[0079] Continue as Figure 9 As shown, the focusing and image stabilization motor 01 may further include a second magnetic sheet 17. Along the first direction Z, the second magnetic sheet 17 and the image stabilization carrier 13 are stacked on the image stabilization base 122. The second magnetic sheet 17 is connected to the image stabilization base 122. The second magnetic sheet 17 is used to attract the second magnet 1422. At this time, the second magnetic sheet 17 is connected to the image stabilization base 122, and the second magnet 1422 is connected to the image stabilization carrier 13. When there is an attraction force between the second magnet 1422 and the second magnetic sheet 17, the image stabilization carrier 13 and the image stabilization base 122 have a force that brings them closer together, thereby pressing down on the first moving member 16 disposed between the focusing carrier 12 and the image stabilization carrier 13, preventing the first moving member 16 from detaching from the focusing carrier 12 and the image stabilization carrier 13.

[0080] The above are as follows Figure 3B as well as Figure 9 In the embodiments shown, both the image stabilization carrier 13 and the focusing carrier 12 are in contact with the first moving member 16. In other embodiments of this application, the following approach may also be used. Figure 10As shown, the focusing and image stabilization motor 01 may further include an intermediate sliding plate 18. The intermediate sliding plate 18 is located on the side of the image stabilization carrier 13 facing the focusing base 11, and the intermediate sliding plate 18 and the image stabilization carrier 13 are stacked in the receiving space 121. Along the second direction X, the intermediate sliding plate 18 is movably connected to the focusing carrier 12, and the image stabilization carrier 13 abuts against the intermediate sliding plate 18. The first image stabilization drive mechanism 14A (as shown) Figure 5 (As shown) This is used to drive the image stabilization carrier 13 and the intermediate sliding plate 18 to move relative to the focusing carrier 12. Along the third direction Y, the image stabilization carrier 13 is movably connected to the intermediate sliding plate 18, and the second image stabilization drive mechanism 14B is used to drive the image stabilization carrier 13 to move relative to the intermediate sliding plate 18. Wherein, 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 image stabilization carrier 13 abuts against the intermediate sliding plate 18. When the first image stabilization drive mechanism 14A drives the image stabilization carrier 13 to move along the second direction X, it causes the intermediate sliding plate 18 to move together relative to the focusing carrier 12. Along the third direction Y, the image stabilization carrier 13 is movably connected to the intermediate sliding plate 18, and the second image stabilization drive mechanism 14B drives the image stabilization carrier 13 to move relative to the intermediate sliding plate 18, and thus relative to the focusing carrier 12. This achieves image stabilization displacement of the image stabilization carrier 13 in the planes containing the second direction X and the third direction Y.

[0081] In some embodiments, continue as follows Figure 9 As shown, the focusing base 11 may include a bottom 111 and a side 112 connected to each other, and a focusing drive mechanism 15 (such as...) Figure 5 The focusing motor 151 (shown) may include a focusing coil 151 and a focusing magnet 152. The focusing coil 151 is disposed on and connected to the focusing carrier 12. The focusing magnet 152 is disposed on and connected to the side portion 112. Along the first direction Z, the focusing magnet 152 drives the focusing coil 151 and the focusing carrier 12 to move relative to the side portion 112. The focusing stabilization motor 01 may also include a drive chip 19. The drive chip 19 is connected to the focusing carrier 12 and electrically connected to the focusing coil 151. Both the drive chip 19 and the focusing coil 151 are disposed on the focusing carrier 12, meaning that the drive chip 19 and the focusing coil 151 will not move relative to each other, facilitating the electrical connection between the focusing coil 151 and the drive chip 19. In addition, in the first direction Z, the thicknesses of the focusing coil 151, the focusing magnet 152, and the focusing carrier 12 overlap, thereby reducing the thickness of the focusing stabilization motor 01.

[0082] In other embodiments, such as Figure 11As shown, a focusing coil 151 is disposed on and connected to the side portion 112. A focusing magnet 152 is disposed on and connected to the focusing carrier 12. Along the first direction Z, the focusing coil 151 drives the focusing magnet 152 and the focusing carrier 12 to move relative to the side portion 112. Distributing the focusing coil 151 on the side portion 112, where movement in the first direction Z is not required, facilitates power supply to the focusing coil 151.

[0083] Continue as Figure 9 As shown, the focus-stabilization 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-stabilization motor 01 may further include a stabilization position sensor 21. The stabilization position sensor 21 is disposed within the second coil 1421 and is used to detect the relative position of the stabilization coil and the second magnet, that is, to detect the relative position of the stabilization carrier 13 and the focus carrier 12.

[0084] Continue as Figure 9 As shown, the focus stabilization 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. By disposing of the second moving member 22 between the focus carrier 12 and the side portion 112, the frictional resistance during relative movement between the focus carrier 12 and the stabilization carrier 13 is reduced, the power required from the focus drive mechanism 15 is reduced, and the size of the focus drive mechanism 15 is reduced.

[0085] In addition, continue as Figure 9 As shown, the side portion 112 has a first groove 1121 and a second groove 1122 on the side facing the focusing carrier 12. At least one second moving member 22 may include a first sliding post 221 and a second sliding post 222. A portion of the first sliding post 221 is disposed in the first groove 1121, and the other portion of the first sliding post 221 abuts against the focusing carrier 12. A portion of the second sliding post 222 is disposed in the second groove 1122, and the other portion of the second sliding post 222 abuts against the focusing carrier 12. The first groove 1121 of the side portion 112 accommodates the first sliding post 221, and the first sliding post 221 abuts against the focusing carrier 12, thereby limiting the first sliding post 221 through the first groove 1121 and the focusing carrier 12, preventing the first sliding post 221 from disengaging from the focusing carrier 12 and the side portion 112. Similarly, the second slide groove 1122 accommodates the second slide post 222, and the part of the second slide post 222 located outside the second slide groove 1122 also abuts against the focusing carrier 12. Thus, the second slide groove 1122 and the focusing carrier 12 limit the second slide post 222, preventing the second slide post 222 from detaching from the focusing carrier 12 and the side portion 112.

[0086] On this basis, continue as Figure 9 As shown, the focusing carrier 12 has a third sliding groove 124 and a fourth sliding groove 125 on the side facing the side portion 112. A portion of the first sliding post 221 is located within the third sliding groove 124, and a portion of the second sliding post 222 is located within the fourth sliding groove 125. The third sliding groove 124 on the focusing carrier 12 further limits the movement of the first sliding post 221. Similarly, the fourth sliding groove 125 on the focusing carrier 12 further limits the movement of the second sliding post 222.

[0087] Furthermore, continue as Figure 9 As shown, the third slide groove 124 is a V-shaped groove. That is, on a plane parallel to the groove depth direction of the third slide groove 124, the sidewalls of the third slide groove 124 form a V-shape. The fourth slide groove 125 is a U-shaped groove. That is, on a plane parallel to the groove depth direction of the fourth slide groove 125, the sidewalls of the fourth slide groove 125 form a U-shape. There is a gap between the second sliding post 222 and the groove wall of the fourth slide groove 125, either facing away from or towards the third slide groove 124. The third slide groove 124 is a V-shaped groove, and the width of the V-shaped groove decreases significantly along the groove depth direction. At this time, another part of the first sliding post 221 is placed in the V-shaped groove to ensure that the first sliding post 221 abuts against the groove wall of the V-shaped groove, thereby ensuring that the focusing carrier 12 moves relative to the focusing base 11 along the extension direction of the V-shaped groove. In addition, the fourth slide groove 125 is a U-shaped groove, and the width of the U-shaped groove decreases less along the groove depth direction. Furthermore, there is a gap between the second sliding column 222 and the fourth sliding groove 125, which is away from or towards the groove wall of the third sliding groove 124, to provide installation allowance, thereby ensuring that when the focusing carrier 12 is installed with the side part 112, the other part of the second sliding column 222 can be installed in the fourth sliding groove 125.

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

[0089] The above are as follows Figure 9 The illustrated embodiment uses a slide bar as an example for the second moving member 22. In other embodiments of this application, the second moving member 22 may also be a ball bearing.

[0090] To further improve the appearance ID of the camera module 200 and achieve power-off centering of the lens 03 in the XY plane, as follows... Figure 9As shown, the focusing and image stabilization motor 01 may further include at least one elastic element 23. One end of the elastic element 23 is connected to the focusing carrier 12, and the other end is connected to the image stabilization carrier 13. The elastic deformation direction of the elastic element 23 is perpendicular to the first direction Z. When the image stabilization drive mechanism 14 drives the image stabilization carrier 13 to move in a plane perpendicular to the first direction Z, the elastic element 23 will undergo elastic deformation. When the image stabilization drive mechanism 14 stops working, the force generated by the elastic deformation of the elastic element 23 pushes the image stabilization carrier 13 to reset, thereby achieving the centering of the image stabilization carrier 13. In addition, the elastic element 23 can provide anti-torsional force to the image stabilization carrier 13, hindering the rotation of the image stabilization carrier 13.

[0091] For example, continue as follows Figure 9 As shown, the focusing and image stabilization motor 01 may include four elastic elements 23, and the image stabilization carrier 13 may include four corner portions 136, with the four elastic elements 23 correspondingly disposed on the four corner portions 136. By having four elastic elements 23 correspondingly disposed on the four corner portions 136, the elastic deformation of the four elastic elements 23 increases the force pushing the image stabilization carrier 13 to return to its original position, ensuring the centering of the image stabilization carrier 13. Furthermore, the four elastic elements 23 increase the torsional strength of the image stabilization carrier 13, further hindering its rotation.

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

[0093] like Figure 13 As shown, the image stabilization carrier 13 may include a first plastic part 133 and a protrusion 137. The protrusion 137 is disposed on the side of the first plastic part 133 opposite to the focusing base 11 and is connected to the first plastic part 133. The elastic member 23 may include a first connecting part 231, an elastic part 232, and a second connecting part 233. The first connecting part 231 is connected to the focusing carrier 12. The elastic part 232 is connected to the first connecting part 231. The second connecting part 233 is connected to the elastic part 232, and a mounting hole 2331 is provided on the second connecting part 233. One end of the protrusion 137 extends into the mounting hole 2331 and abuts or connects with the second connecting part 233. Through the cooperation of the protrusion 137 and the second connecting part 233, the relative fixation of the second connecting part 233 and the image stabilization carrier 13 is achieved. When the focusing carrier 12 and the image stabilization carrier 13 move relative to each other, the first connecting part 231 and the second connecting part 233 move relative to each other. At this time, the elastic part 232, which is in a relaxed state, will deform. When the electronic device stops recording, the image stabilization drive mechanism 14 stops providing driving force. At this time, the elastic part 232 can push the second connecting part 233 to reset, thereby driving the image stabilization carrier 13 to reset, and thus achieving the centering of the image stabilization carrier 13.

[0094] Continue as Figure 9As shown, the focus stabilization motor 01 may include a circuit board 24. The circuit board 24 is mounted on the focus base 11 and connected to the focus base 11. For example... Figure 12 As shown, the focusing carrier 12 may include a second plastic part 126 and a metal support 127. For example... Figure 13 As shown, a metal bracket 127 is embedded within a second plastic component 126, with one end of the metal bracket 127 protruding from the second plastic component 126 away from the focusing base 11. The end of the metal bracket 127 facing the focusing base 11 is electrically connected to a circuit board 24. An elastic element 23 includes at least one of a conductive spring and a conductive suspension wire. The elastic element 23 is electrically connected to the end of the metal bracket 127 away from the focusing base 11, and the elastic element 23 is used to connect with a variable aperture 04 (such as...). Figure 3A (As shown) Electrical connection. The elastic element 23 connects the variable aperture 04 and the metal bracket 127. By supplying power to the circuit board 24, current is transmitted to the metal bracket 127, which is electrically connected to the circuit board 24. The elastic element 23 then supplies current to the variable aperture 04. When the focus stabilization motor 01 is applied to the camera module, the variable aperture 04 is mounted on the stabilization carrier 13. When the stabilization carrier 13 moves the variable aperture 04 relative to the focus carrier 12, the elastic element 23 deforms itself, preventing the connection between the metal bracket 127 and the elastic element 23, and between the elastic element 23 and the variable aperture 04, thus ensuring stable power supply. Furthermore, the metal bracket 127 also 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, image stabilization position sensor 21, focusing coil 151, and focusing 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 by the driver chip 19 to the first coil 1411, second coil 1421, focusing coil 151, image stabilization position sensor 21, or focusing position sensor 20. Alternatively, the metal bracket 127 can directly transmit current to the first coil 1411, second coil 1421, focusing coil 151, image stabilization position sensor 21, or focusing position sensor 20. This achieves power supply to the first coil 1411, second coil 1421, focusing coil 151, image stabilization position sensor 21, and focusing position sensor 20.

[0096] like Figure 14 As shown, circuit board 24 may include a first flexible board 241 and a second flexible board 242. Continuing as... Figure 9 As shown, the first flexible plate 241 is disposed on one side of the focusing carrier 12 and is connected to the metal bracket 127 (as shown). Figure 13(As shown) Connection. Along the first direction Z, the second flexible plate 242 is disposed between the focusing base 11 and the focusing carrier 12, and the first end of the second flexible plate 242 is connected to the first flexible plate 241, and the second end of the second flexible plate 242 is connected to the focusing base 11. When the focusing carrier 12 moves relative to the focusing base 11, the elastic deformation of the second flexible plate 242 causes the first end of the second flexible plate 242 to move with the focusing carrier 12, while the second end remains connected to the focusing base 11, thereby ensuring that during the movement of the focusing carrier 12, power is supplied to the second end of the second flexible plate 242, and the current is transmitted through the first flexible plate 241 to the metal bracket 127 and the elastic element 23, thereby supplying power to the variable aperture 04.

[0097] It is understood that the first flexible plate 241 and the second flexible plate 242 can be a single flexible circuit board 24. Of course, the first flexible plate 241 and the second flexible plate 242 can also both be flexible circuit boards 24, and the two flexible circuit boards 24 can be connected to each other.

[0098] Continue as Figure 14 As shown, the second flexible plate 242 is L-shaped or U-shaped. In this case, with the distance between the two ends of the second flexible plate 242 being the same, the L-shaped or U-shaped structure has a longer length, thus having better deformation capability. This ensures that when the focusing carrier 12 and the focusing base 11 move, the force required for the second flexible plate 242 to deform accordingly is smaller, thereby reducing the maximum driving force required by the focusing drive mechanism 15 and reducing the volume of the focusing drive mechanism 15.

[0099] For example, continue as follows Figure 14 As shown, the second flexible plate 242 may include a first part 2421 and a second part 2422, wherein the first part 2421 is L-shaped and the second part 2422 is U-shaped. The first part 2421 and the second part 2422 are an integrated structure.

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

[0101] Continue as Figure 9As shown, the focusing drive mechanism 15 is connected to the first sidewall 128 of the focusing carrier 12. The first flexible plate 241 is connected to the portion of the second sidewall 129 of the focusing carrier 12 facing the first sidewall 128. The first sidewall 128 and the second sidewall 129 are adjacent to each other. The focusing drive mechanism 15 and the first flexible plate 241 are located on different sidewalls of the focusing carrier 12 for easy installation. Furthermore, when the focusing drive mechanism 15 drives the focusing carrier 12 to move relative to the focusing base 11, the force on the focusing carrier 12 is mainly concentrated on the first sidewall 128 where the focusing carrier 12 connects to the focusing drive mechanism 15. The first flexible plate 241 is connected to the portion of the second sidewall 129 facing the first sidewall 128. That is, the reaction force exerted by the first flexible plate 241 and the second flexible plate 242 on the focusing carrier 12 is located close to the force exerted by the focusing drive mechanism 15 on the focusing carrier 12, thereby reducing the tilting arm and torque of the reaction force.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
