Description

Technical Field

[0001] This invention relates to the field of camera module technology, and more particularly to lens driving devices and camera modules. Background Technology

[0002] With the trend of mobile terminals becoming thinner and lighter, the structure of the camera module configured on them also needs to be miniaturized. However, at the same time, the imaging quality of the camera module is required to be improved. Improving the imaging quality of the camera module not only requires increasing the size of its photosensitive chip and the components that are adapted to it, but also requires increasing the driving force of the driving structure.

[0003] In the camera module structure, the drive structure is mainly used to drive the optical lens to achieve focusing and image stabilization in order to capture clearer images. For most high-pixel camera modules, the drive structure is an essential component. As the size of the image sensor increases, the size of the corresponding optical lens also increases. Since the optical lens is set inside the drive structure, the size of the drive structure also increases accordingly.

[0004] How to increase the size of the image sensor while miniaturizing the overall structure of the camera module, especially ensuring that the driving force provided by the driving structure can drive the optical lens to achieve focusing and image stabilization functions, while also making effective use of the internal space of the driving structure and reducing the size of the driving structure, is a problem that engineers urgently need to solve.

[0005] To address the aforementioned issues, this solution provides a split optical lens driving assembly and camera module structure, which can effectively solve some or most of the problems mentioned above. While increasing the size of the photosensitive chip to improve the imaging quality of the camera module, it can also achieve miniaturization of the driving structure. Summary of the Invention

[0011] Another object of the present invention is to provide an optical lens driving assembly and its camera module, which provides a carrier extension bracket on the focusing part carrier of the drive motor, such that the bracket extends into the space formed by the first lens part and the third lens part to provide support for the second lens part.

[0012] Another object of the present invention is to provide an optical lens drive assembly and its camera module, which makes full use of the internal space of the drive assembly by extending the extension bracket of the focusing carrier of the drive motor from the four corners of the motor and extending into the upper surface of the third lens part through the reserved side wall channel on the lens barrel edge of the first lens part and the third lens part.

[0013] Another objective of the present invention is to provide an optical lens driving assembly and its camera module, which achieves miniaturization of the overall driving structure by reserving a clearance groove on the lower surface of the focusing carrier, so that the third lens mounting part on the image stabilization carrier is partially disposed in the clearance groove, thereby reserving the position of the third lens mounting part.

[0014] Another objective of the present invention is to provide an optical lens driving assembly and a camera module thereof, which fixes the third lens part on the third lens mounting part formed on the image stabilization carrier by forming a third lens mounting part on the bottom surface of the image stabilization carrier, thereby ensuring the stability of the third lens part mounting.

[0015] Another object of the present invention is to provide an optical lens drive assembly and its camera module, which prevents excessive movement of the focusing part carrier by forming a limiting space for the focusing part on the carrier of the image stabilization part.

[0048] The present invention will now be further described in conjunction with specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0049] In the description of this invention, it should be noted that directional terms such as "center," "lateral," "longitudinal," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection, a contact connection, or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0053] As a crucial imaging component in camera modules, the image sensor plays a vital role in the module's structure. Increasing the size of the image sensor can effectively improve the image quality of the camera module. To meet the trend of thinner and lighter mobile devices, existing camera modules also need to achieve miniaturization in their overall structure. The increase in image sensor size, especially with the gradual increase in the image sensor's sensor area, will lead to an increase in the size and weight of the corresponding optical lens. The drive structure is mainly used to drive the optical lens to achieve focusing and image stabilization functions. In conventional solutions, as the size of the optical lens increases, the drive structure needs to provide greater driving force to achieve the lens's focusing and image stabilization functions.

[0054] To enable the drive structure to provide greater driving force, the structure of the drive structure itself needs to be improved. In the existing technology, the driving force of the drive structure mainly comes from the interaction force generated between the magnet and the coil. While increasing the volume of the magnet or the number of turns of the coil can provide greater driving force, it will increase the volume of the drive structure and generate more heat and increase energy consumption during the operation of the drive structure.

[0055] In this embodiment, in some of the described embodiments, an orthogonal coordinate system (X, Y, Z) is used for explanation. The Z direction is the optical axis direction, which is the front-to-back direction. The X and Y directions, which are orthogonal to the Z-axis, are taken as the orthogonal directions of the optical axis. The X direction is the up-down direction (or left-to-right direction), and the Y direction is the left-to-right direction (or up-down direction). The plane orthogonal to the optical axis is the plane formed by the X and Y directions. "Radial" is the direction orthogonal to the Z-axis, and "axial" refers to the corresponding arrangement between two orthogonal planes of the Z-axis, which includes not only directions parallel to the Z-axis but also directions close to being parallel to the Z-axis, such as in... Figure 8 As shown, in this application, the direction of the optical axis is the direction of the Z-axis, and the direction perpendicular to the optical axis is the X / Y direction.

[0056] This solution provides an optical lens driving component 1, such as... Figures 1 to 4As shown, an optical lens drive assembly 1 includes an optical lens 10 and a drive motor 20. The optical lens 10 is a split optical lens, which includes multiple lens sections. In this application, the optical lens 10, i.e., the split optical lens, has an optical axis. Along the optical axis from the image side to the object side, there are sequentially a first lens section 11, a second lens section 12, and a third lens section 13. The first lens section 11, the second lens section 12, and the third lens section 13 form the imageable optical system in this application. The first lens section 11 includes a first lens barrel 111 and at least one first lens group 112. The second lens section 12 includes a second lens barrel 121 and at least one second lens group 122. The third lens section 13 includes a third lens barrel 131 and at least one third lens group 132. The lens group includes at least one lens and more lens combinations, not specifically a plurality of structures. In one specific embodiment, the optical lens has eight elements, including four first elements 112, two second elements 122, and two third elements 132. The number of elements is not limited to this arrangement. In another modified embodiment, the first element 112 has five elements, the second element 122 has one element, and the third element 132 has two elements. These are two examples of how to arrange the number of elements in a split-type lens. In other embodiments, the number of elements is not limited to these two arrangements. Along the optical axis, from the object side to the imaging side, the sensitivity of the optical elements decreases sequentially. In optical design, it is desirable to optimize optical performance by moving the structured stop backward, preferably to the position of the third or fourth element. This also results in a smaller aperture for the corresponding element, facilitating the formation and assembly of external dark objects. Therefore, it is preferable to have the first lens section 11 with a small outer diameter lens group, and the second lens section 12 and the third lens section 13 with relatively large outer diameter lens groups. Furthermore, since the three lens components are pre-assembled separately and ultimately assembled into a single unit, the inner and outer diameters of the lens components exhibit different sized correspondences. In this application, the diameter of the lens in the first lens group 111 is smaller than the diameters of the second lens group 121 and the third lens group 131. Specifically, the inner diameter of the first lens component 11 is much smaller than the inner diameter of the second lens group 12, and the inner diameter of the second lens group 12 is smaller than the inner diameter of the third lens group 13. This ensures that the inner diameter of each lens group is compatible with the image of the optical imaging system, guaranteeing the imaging accuracy of the optical system. Simultaneously, the outer diameters of the first lens barrel 111 and the third lens barrel 131 are larger than that of the second lens barrel 121, facilitating the pre-assembly of the first lens barrel 111 and the third lens barrel 131. This also facilitates the active calibration assembly of the second lens barrel 121, allowing for improved imaging accuracy of the optical system through active calibration of the relative positional relationship of at least one lens group.

[0057] According to one aspect of this application, an optical lens drive motor 20 is provided, such as... Figures 1 to 8As shown, the drive motor 20 includes a protective housing 21, a focusing section 22, an image stabilization section 23, a conducting section 24, a holding section 25, a base 26, and a support section 27. The protective housing 21 houses other components within its internal space, providing corresponding protection for the internal components of the drive motor 20. The focusing section 22 houses the optical lens section and, under its driving force, drives the optical lens to move along the optical axis. The focusing section 22 is disposed inside the image stabilization section 23, which drives the optical lens 10 and the focusing section 22 to move in a direction perpendicular to the optical axis. In some optional embodiments, the holding section 25 of the optical lens drive motor 20 elastically connects the focusing section 22 and the image stabilization section 23 to hold the focusing section 22 inside the image stabilization section 23. Due to the elasticity of the holding section 25, the focusing section 22 can return to its initial position after focusing. The drive motor 20 also includes a conductive section 24, which mainly ensures the continuity of the drive motor's circuitry. This section primarily connects the focusing unit 22, the image stabilization unit 23, and the external power supply to ensure circuit stability during the operation of the drive motor 20. The base 26 is positioned below the image stabilization unit 23. A support section 27 is provided between the base 26 and the image stabilization unit 23. The support section 27 is located within a reserved area between the image stabilization unit 23 and the base 26 to provide support for the image stabilization unit 23. In some embodiments, the support section 27 slides or rolls against the image stabilization unit 23 during horizontal movement relative to the base 26, reducing resistance during the movement of the image stabilization unit 23 relative to the base 26.

[0058] like Figures 5 to 8 As shown, the focusing unit 22 is mainly used to drive the second lens unit 12 to move along the optical axis, so as to make the camera module form a clear image. The focusing unit mainly includes a focusing carrier 221, a focusing coil 222, a magnet 223, and an image stabilization carrier 231. The second lens unit 12 is fixed to the focusing carrier 221, the focusing coil 221 is disposed on the side wall of the focusing carrier 221, and the magnet 223 is disposed on the image stabilization carrier 231 and faces the focusing coil 221. In this application, the focusing carrier 221 further includes a carrier body 2221, an extension bracket 2222, a coil mounting position 2223, and a clearance groove 2224. The extension bracket 2222 is disposed on the carrier body 2221, extends inward and / or upward from the carrier body 2221 and carries the second lens unit 12, thereby placing the second lens unit 12 above the third lens unit 13.

[0059] The coil mounting position 2223 is disposed on the outer side of the carrier body 2221, located in the middle region of the side of the carrier body 2221. Specifically, the coil mounting position 2223 may be an annular groove formed in the middle of the outer side of the carrier body 2221. In some embodiments, the annular groove may be integrally formed with the carrier body 2221, that is, the coil mounting position 2223 is formed directly on the mold during the injection molding process of the carrier body 2221. The focusing coil 222 is wound around the coil mounting position 2223 formed on the carrier body 2221, and interacts with the magnet 223 surrounding the outside of the focusing coil 222 to drive the focusing part 22 to move along the direction of the optical axis.

[0060] like Figure 12 As shown, the extension bracket 2222 further includes a support portion 22221 and an extension portion 22222. The extension portion 22222 extends from the focusing carrier body 2221 along its upper and / or inner direction. In some preferred embodiments, the extension portion 22222 extends from the four corners or four sides of the focusing carrier body 2221 along its upper and / or inner direction. In some optional embodiments, the extension portion 2222 forms a certain height difference with the upper end surface 2221 of the carrier body to facilitate the installation of the second lens portion 12. The second lens portion 12, which protrudes above the motor carrier, is more conducive to active calibration and reduces the motor shoulder height. One end of the extension 22222 is connected to the carrier body 2221, and the other end is connected to the support part 22221. The support part 22221 is used to support the second lens part 12 and is bonded and fixed to the second lens part 12. In a specific embodiment, the support part 22221 can be a ring-shaped structure. The outer side of the ring-shaped structure is fixed to the extension 22222, that is, the extension 22222 supports the support part 22221 on the upper surface of the carrier body 2221, so that the support part 22221 and the carrier body 2221 have a certain height difference. The upper surface of the support part 22221 is the mounting position of the second lens part 12. The upper surface of the support part 22221 is a horizontal ring-shaped structure, which is bonded and fixed to the lower surface of the second lens barrel 121 of the second lens part 12 and maintains a distance from the upper surface of the carrier body 2221.

[0061] like Figures 3 to 4As shown, the drive motor 20 and the optical lens 10 together constitute the optical lens drive assembly 1 of this application. The optical lens 10 is a split-type optical lens, comprising multiple optical lens sections. In a specific embodiment of this application, the optical lens 10 consists of a first lens section 11, a second lens section 12, and a third lens section 13 sequentially along the optical axis. The first lens section 11 and the third lens section 13 are fixedly connected, with the first lens section 11 fixed above the third lens section 13, i.e., the lower end face of the first lens barrel 111 is fixed to the upper end face of the third lens barrel 131. At least one sidewall channel is formed at the fixing points of the first lens section 11 and the third lens section 13. In this application, two or four sidewall channels are preferred, facilitating external clamping of the second lens section 121 during assembly and maintaining a balanced clamping force. A receiving space is formed between the first lens section 11 and the third lens section 13, and the second lens section 12 is disposed within this receiving space. The second lens portion 12 is fixed to the focusing carrier 221. The connection position of the first lens portion 11 and the third lens portion 13 forms a sidewall channel, which communicates with the accommodating space. The focusing carrier 221 further includes an extension bracket 2222, which extends through the sidewall channel into the accommodating space and is fixed to the second lens portion 12, thus positioning the second lens portion 12 between the first lens portion 11 and the third lens portion 13. Under the focusing drive of the focusing unit 22, the second lens portion 12 can be driven to move along the optical axis within the accommodating space to perform focusing or zooming movements. The third lens portion 13 is disposed inside the image stabilization unit 23 and is fixed to the image stabilization unit 23. The third lens section 13 is fixedly connected to the first lens section 11, and the second lens section 12 is fixed to the focusing section 22. The focusing section 22 is housed inside the image stabilization section 23 and is held inside the image stabilization section 23 by the holding section 25. The image stabilization section 23 can drive the first lens section 11, the second lens section 12, and the third lens section 13 to move synchronously along a direction perpendicular to the optical axis.

[0062] In one specific embodiment, the light-incident aperture of the second lens barrel 121 of the second lens section 12 is larger than the light-outcident aperture. At the same time, the inner lower surface of the second lens barrel 121 serves as the support surface of the second lens group 122, which can reduce the risk of generating stray light and make subsequent assembly easier.

[0063] In one specific embodiment, in order to allow light to pass through the second lens section 12, a through hole is formed on the support section 22221. The diameter of the through hole is larger than the diameter of the light-passing hole of the second lens section 12, so that light passes through the second lens section 12 and enters the third lens section 13. The inner diameter of the support section 22221 is larger than the diameter of the light-entry hole of the third lens section 13, and also larger than the diameter of the light-exit hole of the second lens section 12. This can reduce the risk of stray light being generated between the two lens groups, and at the same time, allow the support section 22221 to avoid the light path diffusion path of the optical lens 10 it is located in.

[0064] Specifically, in this application, the number of extension portions 22222 of the focusing carrier extension bracket 2222 is multiple. In a specific embodiment, the number of extension portions 22222 is at least three, which are evenly arranged on the upper surface of the focusing carrier to ensure the flatness of the second lens portion 12. The extension bracket extends upward and / or inward along the corner or edge of the carrier body 2221 to a certain height and extends into the accommodating space formed by the first lens portion 11 and the third lens portion 13. After the first lens portion 11 and the third lens portion 13 are fixed, at least one sidewall channel is formed on the side of the connection between the first lens portion 11 and the third lens portion 13. The extension portion 22222 extends into the accommodating space through the sidewall channel formed by the first lens portion 11 and the third lens portion 13. One end of the extension portion 22222 is connected and fixed to the support portion 22221, and the second lens portion 12 is disposed on the upper end surface of the support portion 22221, so that the second lens portion 12 can move along the direction of the optical axis in the accommodating space to focus or zoom under the action of the focusing portion 22.

[0065] In this application, such as Figure 3 As shown, the second lens section 12 is located in the internal space formed by the second lens section 11 and the third lens section 13. The extension bracket of the carrier body 2221 extends into the accommodating space through a side wall channel reserved at the lens barrel end of the first lens section 11 and the third lens section 13, and is fixed to the second lens section 12 through the bearing part 222221 on the extension bracket 2222. The side wall channel reserved at the lens barrel end of the first lens section 11 and the third lens section 13 is used to avoid the extension part 22222 so that it can extend into the accommodating space. The side wall channel also has a certain height, which is mainly used to reserve the distance for the carrier body 2221 to move along the optical axis so that the second lens section 12 can be adjusted in position within the limited space.

[0066] In one specific embodiment, the height of the sidewall channel exceeds 520 μm to provide sufficient travel for the focusing carrier 221 and the second lens section 12. In the specific embodiments involved in this application, applicable to large image plane optical designs, when the number of elements in the first lens group of the first lens section 11 is greater than 3 (image plane + focal length conditions), the focusing travel (or movable travel) of the focusing section 22 or the second lens section 12 using the design scheme of this application is ≤360 μm, while under similar specifications, using an integrated lens design scheme, the required focusing travel is ≥370 μm. This application achieves clear imaging by only driving a portion of the lens or lens group of the optical lens 10 to move, while also reducing the driving force requirements for the focusing unit 22. In addition to simplifying the structural design of the focusing unit 22, the extension bracket 2222 is used to fix the second lens unit 12 within the accommodating space formed by the first lens unit 11 and the third lens unit 13, so that the second lens unit 12 is positioned above the third lens unit 13 and above the drive motor 20, thereby achieving a low shoulder height and miniaturization of the overall drive motor 20 structure. At the same time, the first lens unit 11 fixed above the third lens unit 13, the second lens unit 12 fixed on the extension bracket, and the third lens unit 13 form a complete optical system. Through the reasonable design of the extension bracket and lens barrel, the optical performance of the lens is reasonably optimized and the risk of stray light is reduced.

[0067] In one specific embodiment, the focusing unit 22 may further include a position sensing element, which may be disposed on the side of the carrier body 2221. The position sensing element is mainly used to sense the position of the focusing carrier 221 and feed its position information back to the control center. The control center adjusts the current in the focusing coil 222 in real time according to the information fed back by the position sensing element, including the magnitude and direction of the current, so as to quickly adjust the position of the focusing carrier 221 in the imaging to obtain a clearer image. As for the specific shape and the position of the position sensing element, it can be set according to the specific requirements of the drive motor 20, which will not be described in detail here.

[0068] In some embodiments, such as Figures 3 to 10As shown, the drive motor 20 also includes an image stabilization unit 23, which is mainly used to drive the optical lens to move along a direction perpendicular to the optical axis, i.e., the X / Y direction, in order to correct the shake of the optical lens. The focusing unit 22 is housed inside the image stabilization unit 23. Specifically, the focusing carrier 221 is housed inside the image stabilization carrier 231. The focusing carrier 221 is connected to the image stabilization carrier 231 through the holding part 25. Furthermore, through the centering and holding function of the holding part 25, the second lens part 121 fixed to the focusing carrier 221 is kept in alignment with the optical axis relative to the first lens part 111 and the third lens part 131. The retaining part 25 is an elastic component. In one specific embodiment, the retaining part 25 is a spring-loaded structure, with one end connected to the focusing carrier 221 and the other end connected to the image stabilization carrier 231. Through the action of the retaining part 25, the focusing carrier 221 is suspended inside the image stabilization carrier 231. The retaining part 25 includes an upper spring 251 and a lower spring 252. The upper spring 251 is disposed on the upper end surface of the image stabilization carrier 231 and connected to the upper end surface of the focusing carrier 221. The lower spring 252 is disposed on the lower end surface of the image stabilization carrier 231 and connected to the upper end surface of the focusing carrier 221. The lower end face of body 221 is connected to the upper spring 251 and the lower spring 252, which act as retaining members to hold the focusing carrier 221 inside the image stabilization carrier 213. The springs also facilitate the connection between the focusing unit 22 and the image stabilization unit 23, ensuring a stable connection between the two components. Furthermore, when the focusing unit 22 drives the second lens unit 12 to adjust its position along the optical axis under the action of a driving force, after the driving force disappears, the elastic restoring force of the upper spring 251 and the lower spring 252 causes the focusing unit 22 to drive the second optical lens unit back to its initial position. In other optional embodiments, the retaining member 25 can also be made of other materials, such as shape memory alloy metal, which not only facilitates the connection between the focusing unit 22 and the image stabilization unit 23 but also provides a restoring force to the focusing unit 22, allowing it to drive the second lens unit 12 back to its pre-adjustment position. In another specific embodiment, the retaining part 25 can be a ball and magnetic yoke structure, that is, the focusing carrier 221 and the image stabilizing carrier 231 are in contact through the ball structure, and the ball is restricted in the ball groove formed by the focusing carrier 221 and the image stabilizing carrier 231 by the magnetic yoke and other structures, and the resetting is achieved by the mutual attraction of the magnetic yoke and the magnet.

[0069] This application provides a specific structure for an image stabilization unit 23, which includes an image stabilization carrier 231, an image stabilization coil 232, a magnet 223, an image stabilization controller 234, a position sensor 235, and a fastener 236. The image stabilization carrier 231 has an internal accommodating space for housing a focusing carrier 221 on which a second lens section 12 is mounted. The magnet 223 is disposed on the side of the image stabilization carrier 231, surrounding the side of the carrier. The image stabilization carrier 231 has mounting positions for the magnet 223, with at least one magnet mounting position 2312 integrally formed on the side wall of the image stabilization carrier 231. The image stabilization coil 232 is disposed on the lower end face of the magnet 223, and the upper surface of the image stabilization coil 232 is parallel to the lower surface of the magnet 223. The position sensor 235 is configured to sense the position of the image stabilization unit 23 and feed back the position information of the image stabilization unit 23 to the image stabilization controller 234. The controller 234 is disposed on the image stabilization unit 23 and is mainly used to control the distance of movement of the image stabilization unit 23 based on the information fed back by the position sensor 235, so as to correct the shaking during the shooting process and obtain a clear image. In a specific embodiment of this application, the position sensor 235 includes an X-direction sensor 2351 and a Y-direction sensor 2352. The position sensor 235 can be located in the middle of the stabilization coil 232 or in other positions, as long as it can detect the horizontal position of the stabilization unit 23. Its specific location is not limited here. The fastener 236 is located on the outer surface of the stabilization carrier 231 and is mainly used to fix the magnet 223 onto the stabilization carrier 231. In this solution, to reduce the weight of the stabilization unit 23 and lower the driving force requirement for it, a mounting position for the magnet 223 is reserved on the stabilization carrier 231. The portion of the stabilization carrier 231 for mounting the magnet 223 is reserved, and the magnet 223 is subsequently fixed onto the stabilization carrier 231 using methods such as adhesive bonding. In another embodiment, the fastener 236 can be an injection molded part. That is, during the injection molding process of the anti-shake carrier 231, the magnet 223 is directly integrally formed with the anti-shake carrier 231. Setting the fastener 236 as an injection molded part can simplify the process of fixing the magnet 223 to the anti-shake carrier 231 and reduce the cost in the manufacturing process.

[0070] In one specific embodiment, the focusing part 22 and the image stabilization part 23 of the drive motor 20 adopt a shared magnet structure, that is, the magnet 223 of the focusing part 22 and the magnet 223 of the image stabilization part 23 are the same set of magnets, and the magnet 223 is disposed on the image stabilization carrier 231 of the image stabilization part 23.

[0071] Specifically, the image stabilization unit 23 provided in this application can drive the optical lens 10 to adjust its position in the X / Y direction to achieve shake correction during shooting. In the image stabilization unit 23, the image stabilization carrier 231 has a bumper 2311, a magnet mounting position 2312, a limiting body 2313, a first ball groove 2314, and a Hall position sensing position 2315. Specifically, the bumper 2311 is disposed on the upper surface of the image stabilization carrier 231. The bumper 2311 can be at least one small protrusion extending upward from the four corners of the image stabilization carrier 231, mainly used to prevent the focusing unit 22 from hitting the motor housing due to excessive movement during drop or collision. At least two limiting bodies 2313 are disposed on the inner side of the image stabilization carrier 231. The limiting bodies 2313 extend from the inner side of the image stabilization carrier 231 and have a certain width, which can fix the third lens part 13 inside the limiting bodies 2313, so that the third lens part 13 is fixedly disposed with the image stabilization carrier 231. When the image stabilization carrier 231 moves along the X / Y direction under the action of driving force, it can drive the third lens part 13 to move synchronously in the X / Y direction. Since the image stabilization part 23 drives the optical lens to move relative to the drive motor base 26 along the X / Y direction, in order to reduce the friction between the drive motor base 26 and the image stabilization carrier 231, a corresponding support part 27 is provided between the two. The support part 27 is mainly used to support the image stabilization carrier 231 on the upper surface of the base 26 to reduce the friction between the two relative to each other. In one specific embodiment, the support 27 can be a ball bearing 271, and there can be multiple balls bearing 271. They are disposed between the base 26 and the image stabilization carrier 231. The lower surface of the image stabilization carrier 231 is provided with a first ball bearing groove 2314, and the corresponding base 26 is provided with a corresponding second ball bearing groove 264. The first ball bearing groove 2314 and the second ball bearing groove form a space for receiving the balls bearing 271. The balls bearing 271 are confined within the track formed by the first ball bearing groove 2314 and the second ball bearing groove 264. Under the action of the driving force, the image stabilization carrier 231 moves relative to the base 26 along the pre-designed ball bearing groove, thereby realizing the position adjustment of the optical lens in the X / Y direction.

[0072] Specifically, such as Figure 10As shown, the image stabilization unit 23 needs to drive the lens parts of the split optical lens to move synchronously. A limiting body 2313 is provided on the corresponding image stabilization carrier 231. There can be multiple limiting bodies 2313, which are located on the inner side of the image stabilization carrier 231. The number of limiting bodies 2313 is at least three. In one specific embodiment, the number of limiting bodies is four. Each limiting body 2313 includes a horizontal portion 23131 and a vertical portion 23132. The horizontal portion 23131 extends horizontally along the inner side of the image stabilization carrier for a certain distance. One end of the vertical portion 23132 is connected to the horizontal portion 23131 and extends upward along the optical axis. An abutment groove 2224 is provided on the inner side of the focusing carrier body 2221 near the second lens portion 12. The abutment groove is located at the four corners of the focusing carrier body 2221. It can be used to prevent excessive movement of the focusing carrier 221 and to reserve installation space for the third lens portion 13. In this solution, the abutment groove 2224 on the focusing carrier 221 is located at the four corners of the image stabilization carrier 231. The abutment groove 2224 at least accommodates part of the third lens mounting portion. A receiving space is formed between the image stabilization carrier 231, the horizontal portion 23131, and the vertical portion 23132. The abutment groove 2224 on the focusing carrier 221 corresponds to the receiving space, so that part of the focusing carrier 221 is restricted inside the limiting body 2313. When assembling the focusing carrier 221 and moving it along the optical axis, it helps to ensure the collimation of its focusing. The third lens section 13 is fixed to a limiting body 2313 disposed on the image stabilization carrier 221. In some optional embodiments, the third lens section 13 is supported by the vertical portion 23132 of the limiting body 2313. Furthermore, the outer side of the limiting body 2313 near the optical axis of the lens is fixed to the third lens section 13, so that the third lens section 13 is fixedly connected to the image stabilization unit 23. In some optional embodiments, a plurality of magnets 223 are disposed on the side of the image stabilization carrier 231, and the image stabilization coil 232 is disposed on the base 26 and located below the magnets 223. A driving force is generated between the magnets 223 and the image stabilization coil 232. When the image stabilization unit 23 moves under the action of the driving force, it will drive the first lens section 11, the second lens section 12 and the third lens section 13 to move synchronously, so as to realize the position adjustment of the entire optical lens in the X / Y direction.

[0073] In this application, the drive motor 20 also includes a base 26, such as Figure 11As shown, the base 26 has a light-transmitting hole 261, the center of which is aligned with the optical axis of the optical lens 10. The base 26 also includes a position sensor mounting position 262, a controller mounting position 263, a second ball bearing groove 264, and an image stabilization coil mounting position 265. The image stabilization coil mounting position 265 is located on the upper surface of the base 26. The image stabilization coil 232 is connected to the base 26 via the reserved mounting position of the image stabilization coil 265. The position sensor mounting position 262 is disposed on the base 26 and is set to a low position. A recessed structure on the upper surface of the base 26 is used to accommodate the position sensor 235 inside the recess. The controller mounting position 263 is disposed on the base 26 and is positioned below the recess on the upper surface of the base 26 to accommodate the anti-shake controller 234 of the anti-shake unit 23 inside. This recessed structure design, which accommodates the position sensor 235 and the anti-shake controller 234 of the anti-shake unit 23 inside the base 26, can fully utilize the space of the base 26 and reduce the overall height of the drive motor 20. The placement of position 263 on base 26 is not restricted, as long as it does not interfere with the position of position sensor mounting position 262. The upper surface of base 26 has a second ball groove 264, which corresponds to a first ball groove 2314 on the lower surface of the anti-shake carrier 231. The first ball groove 231 and the second ball groove 2314 form a confining space for the ball 271, thus confining the ball 271 within the formed space. The shape of the ball groove can be hemispherical or bowl-shaped. In another embodiment… In this example, the shape of the ball groove can be V-shaped, and the specific shape of the ball track is not limited here. The ball 271 is confined within the ball groove formed by the first ball groove 2314 and the second ball groove 264 to provide support for the anti-shake carrier 231. Under the action of the driving force, the anti-shake carrier 231 can be adjusted in position relative to the base 26 in the X / Y direction. Due to the supporting effect of the ball 271, the frictional force between the anti-shake carrier 231 and the base 26 can be reduced, thereby reducing the requirement for the anti-shake driving force.

[0074] In one specific embodiment, a conductive portion 24 of a drive motor 20 is provided, such as... Figures 7 to 8As shown, the conductive part 24 can be a flexible circuit board 241, which can be bent arbitrarily. In this application, the flexible circuit board 241 is disposed on at least two sides of the image stabilization carrier 231, and includes at least one end face and one side wall. The end face refers to the top and bottom end faces of the image stabilization carrier, and the side wall refers to the four side walls of the image stabilization carrier. It includes a connecting part 2411, a focusing part flexible circuit board 2412, and an image stabilization conductive flexible circuit board 2413. The focusing part flexible circuit board 2412 is disposed on the top or bottom end face of the image stabilization carrier 231. The plane on which the focusing part flexible circuit board 2412 is located is a first plane. One end of the focusing part flexible circuit board 2412 is conductive to at least one upper spring 251 or lower spring 252 of the focusing carrier 221 of the focusing part 22. Furthermore, the spring and the focusing part flexible circuit board 2412 can be conductive through the terminal of the focusing carrier 221. The other end of the focusing section flexible plate 2412 is connected to the connecting portion 2411. To make reasonable use of the internal space of the module, the connecting portion 2411 can be a bent structure, that is, one end of the bent structure is connected to the focusing section flexible plate 2412, and the other end is connected to the image stabilization section connecting flexible plate 2413. The plane on which the image stabilization section flexible plate 2413 is located is the second plane. In a specific embodiment, the connecting portion 2411 can be a right-angled bend, connecting the focusing section flexible plate 2412 and the image stabilization section flexible plate 2413 located on different sides of the image stabilization carrier 231. Specifically, the planes on which the focusing flexible plate 2412 and the image stabilization flexible plate 2413 are located are perpendicular to each other. That is, the focusing flexible plate 2412 is located on the top or bottom end face of the image stabilization carrier 231, and the image stabilization flexible plate 2413 is located on the side wall of the image stabilization carrier 231. The first plane and the second plane are approximately perpendicular. The focusing flexible plate 2413 extends on the second plane to the base 26 and is connected to the base 26, thereby ensuring the continuity of the internal wiring of the drive motor 20. The image stabilization flexible plate 2413 is connected to the pre-reserved terminal on the base 26, thereby ensuring the continuity of the internal wiring of the drive motor 20. In one embodiment, the image stabilization flexible plate 2413 may extend along multiple side walls of the image stabilization carrier 231, with at least two side walls being perpendicular to each other. Because the flexible circuit board itself has a certain degree of flexibility, while connecting the circuitry of the focusing section 22 and the image stabilization section 23 to external circuitry, it can also reduce the resistance when the focusing section 22 moves relative to the image stabilization section 23. The extensions of the focusing section flexible circuit board 2412, the connecting portion 2411, and the image stabilization section flexible circuit board 2413 on multiple side walls or end faces are reserved with a certain bending allowance or movable gap to ensure sufficient travel when the image stabilization carrier 231 moves relative to the base 26, reducing the reaction force during motor reset. In another embodiment, the connecting portion 24 can also be a spring-loaded structure, which can also serve as a conductor while simultaneously achieving elastic reset of the spring itself.

[0075] In this application, as Figure 9 As shown, the focusing carrier 221 is housed inside the image stabilization carrier 231. To further protect the components of the drive motor 20, the optical lens drive assembly 1 also includes a protective shell 21. The protective shell 21 has a shell light-transmitting hole 211 and a shell receiving portion 212. The shell light-transmitting hole 211 is mainly used to accommodate the optical lens 10, such that the shape of the light entrance hole of the optical lens 10 and the shape of the shell light-transmitting hole 211 are consistent. The diameter of the shell light-transmitting hole 211 is greater than or equal to the diameter of the light entrance hole of the optical lens 10. The center of 211 is aligned with the optical axis of the optical lens 10, thereby allowing the optical lens 10 to receive more external light. The internal space formed by the motor housing accommodating portion 212 includes the optical lens accommodating portion 2121 and the drive motor accommodating portion 2122, which can accommodate the drive motor 20 and the optical lens 10. The housing accommodating portion 212 is fastened to the base 26, and the space formed between it and the base 26 accommodates the drive motor 20 and the optical lens 10 inside this space, thus providing corresponding protection for the internal components. The bottom surface of the drive motor accommodating portion 2122 is fixed to the side of the base 26 to form a covering space, which covers the components of the drive motor 20, thus providing protection for the internal components. In a specific embodiment, the lens accommodating portion 2121 is a hollow cylinder, used to accommodate the optical lens 10 and the part of the structure protruding from the main body of the drive motor 20 inside it. In order to reserve space for the adjustment of the position of the optical lens 10, the diameter of the lens accommodating portion 2121 is larger than The diameter of the optical lens 10 housed inside, and the specific size of the reserved gap, are determined according to the adjustable stroke of the optical lens 10 in a plane perpendicular to the optical axis; the focusing part 22 and the image stabilization part 23 of the drive motor are placed in the drive motor housing 2122, the main body of the drive motor housing 2122 is a hollow cuboid, and the housing space formed between the cuboid and the base 26 houses the components of the drive motor 20 inside to form protection, and the drive motor housing 2122 is arranged around the drive motor.

[0076] Specifically, such as Figure 9As shown, the optical lens receiving portion 2121 and the drive motor receiving portion 2122 are connected through the upper surface of the drive motor receiving portion 2122. That is, the optical lens receiving portion 2121 has an extended horizontal surface at one end, which is bonded and fixed to the upper surface of the drive motor receiving portion 2122 to form the housing receiving portion 212. In another specific embodiment, the optical lens receiving portion 2121 and the drive motor receiving portion 2122 can be integrally molded. During the injection molding process, the shapes of the optical lens receiving portion 2121 and the drive motor receiving portion 2122 are directly formed in the mold. The two parts are molded into one piece through injection molding, which simplifies the process and the assembly steps. The protective shell can be made of metal, such as iron or alloy, and the material needs to have a certain degree of hardness to provide better protection for the internal components. Specifically, the side of the first lens part 11 and the third lens part 13 is fixed with at least one side wall channel, and the optical lens receiving part 2121 is arranged around the side wall channel. The optical lens receiving part 2121 is arranged around at least a portion of the outer periphery of the first lens part 11 and the second lens part 12.

[0077] In one specific embodiment, to facilitate the movement of the first lens section 11, the second lens section 12, and the third lens section 13, a first gap is formed between the upper surface of the first lens section 11 and the lens receiving section 2121 to facilitate the movement of the optical lens 10; a second gap is formed between the side of the first lens section 11 and the lens receiving section 2121, which is mainly used to allow distance for the optical lens 10 to move in the horizontal direction. The distance of the second gap is greater than the distance of the first gap, and the two gaps are on different planes and are set around the first lens section 11 in different directions; a third gap is formed between the side of the image stabilization section 23 of the drive motor 20 and the motor receiving section 2122, which is mainly used to reserve a movement gap for the image stabilization section 23 to ensure the normal adjustment of the position of the optical lens 10. This housing arrangement can increase the size of the photosensitive chip while ensuring the low shoulder height of the overall drive motor, which is conducive to the miniaturization of the overall structure.

[0078] According to a second aspect of the present invention, a camera module includes:

[0079] The optical lens 10 and drive motor 20 are as described above;

[0080] A photosensitive component, with the base positioned between the photosensitive component and the lens assembly, is used to capture light and form an image.

[0081] The camera module can also be a chip-based image stabilization camera module. The base 26 is further provided with corner protrusions, which are located at the four corners of the lower surface of the base 26 and integrally formed with the base 26. Each corner protrusion has a sensing magnet mounting hole, into which a corresponding sensing element is embedded to sense the position of the photosensitive chip and feed the position information of the photosensitive chip back to the control center. This allows the motor and the photosensitive chip to work together to quickly adjust the positions of the two elements, thereby improving the imaging efficiency of the camera module. Simultaneously, the photosensitive chip and the optical lens can work together to achieve image stabilization with a greater stroke, solving the problem of increased driving force requirements due to the increased size of the photosensitive chip and the increased mass of the optical lens. This also ensures the accuracy of the motor driving the optical lens while addressing the issue of the coordinated movement of the photosensitive chip and the optical lens.

[0082] To address the increased driving force requirements resulting from larger chip sizes, the optical lens drive assembly 1 provided in this application utilizes a split optical lens, dividing the optical lens into a first lens section, a second lens section, and a third lens section. The focusing section of the drive motor drives the second lens section to move along the optical axis within the accommodating space formed by the first and third lens sections, while the image stabilization section of the drive motor drives the entire optical lens to move in a direction perpendicular to the optical axis. This configuration allows for a direct linkage between the motor and the lens, effectively solving the problem of increased driving force requirements due to larger image sensor sizes, and also enabling miniaturization of the overall structure.

[0083] The basic principles, main features, and advantages of this invention have been described above. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
