Description

Technical Field

[0001] This application relates to the field of camera modules, and more particularly to a driving device, an assembly method thereof, and a camera module. Background Technology

[0002] With the popularization of mobile electronic devices, the technology of camera modules used in mobile electronic devices to help users acquire images (such as videos or pictures) has developed and progressed rapidly. In recent years, camera modules have been widely used in many fields such as medical care, security, and industrial production.

[0003] With changing and evolving market demands, consumers are increasingly requiring diverse features in camera modules. For example, they require image stabilization and autofocus to improve image quality. Optical autofocus (AF) refers to the function of linearly moving a lens mount or image sensor along the optical axis to create a sharp image at the image sensor (CMOS, CCD, etc.) located behind the lens. Optical image stabilization (OIS) refers to the function of adaptively moving the lens mount or image sensor in a direction that compensates for lens shake, thereby improving image sharpness. Motors are an indispensable component of high-performance camera modules. During operation, the motor drives the lens to move, enabling optical autofocus and image stabilization during shooting.

[0004] To meet increasingly diverse market demands, the optical components (e.g., image sensors, optical lenses) of camera modules in terminal devices are becoming larger and heavier, placing higher demands on the driving force of motors.

[0005] Specifically, as terminal devices evolve towards miniaturization and thinner designs, current terminal devices (e.g., mobile phones) face significant limitations in the size of camera modules. However, to provide sufficient driving force for optical components, the volume occupied by the motor must increase along with the size and weight of the optical components it drives. With the size of the camera module constrained by the miniaturization of terminal devices, while optical components are trending towards larger size and greater weight, the driving force provided by existing motors cannot be increased accordingly.

[0006] Furthermore, to achieve better optical autofocus and optical image stabilization, a large driving stroke is required for the optical components. However, without increasing the size of the motor, it is difficult to improve the driving force of existing motors. With limited driving force, the heavier the optical components, the shorter the stroke that the motor can drive the optical components to move, which will affect the focusing and image stabilization capabilities.

[0007] Furthermore, the heavier the optical components, the slower the motor drives them, and the longer it takes for the components to reach their intended positions, which also affects focusing and image stabilization. To meet the required driving speed of the motor for the optical components, the motor structure needs to be modified, leading to a more complex structure, an increased number of parts, and a tendency for the overall thickness of the device to increase. Summary of the Invention

[0008] One advantage of this application is that it provides a driving device, an assembly method thereof, and a camera module. The driving device of the camera module avoids the unexpected movement of the driven object during the driving process by arranging the various parts of its elastic components in a specific pattern, thereby reducing the tilt tolerance of the driving device and improving the assembly accuracy of the camera module.

[0009] Another advantage of this application is that it provides a driving device, its assembly method, and a camera module. In the driving device, the focusing elastic part of the elastic member is arranged in a rotationally symmetrical manner relative to the optical axis set by the optical lens. During the process of driving the object to move along the Z-axis for optical focusing, the focusing elastic part can suppress the object from translating along the X-axis and Y-axis, and can also suppress the object from rotating along the Z-axis. In this way, the flatness of the elastic member is improved, thereby reducing the tilt tolerance of the driving device and improving the assembly accuracy of the camera module.

[0010] Another advantage of this application is that it provides a driving device, its assembly method, and a camera module. In the driving device, the anti-shake elastic portion of the elastic member is arranged in an axisymmetric manner with respect to the X-axis and Y-axis. During the process of driving the object to move along the X-axis and Y-axis in a plane perpendicular to the optical axis, the anti-shake elastic portion can suppress the outer carrier from rotating around the Z-axis. In this way, the flatness of the elastic member is improved, thereby reducing the tilt tolerance of the driving device and improving the assembly accuracy of the camera module.

[0011] Another advantage of this application is that it provides a driving device, its assembly method, and a camera module. The driving device can be assembled sequentially along the optical axis during the assembly process, which not only simplifies the assembly method of the driving device and saves costs, but also reduces the assembly tolerance of the driving device during the assembly process and improves the assembly accuracy of the driving device.

[0012] One advantage of this application is that it provides a driving device and a camera module, wherein the driving device can provide a large placement space for the driving component of its driving part, thereby increasing the volume of the driving component of the driving part and improving the driving force that the driving part can provide.

[0013] Another advantage of this application is that it provides a driving device and a camera module, wherein the driving device mainly increases the placement space of the driving component by reasonably arranging the driving component (e.g., coil) and the guide support structure of the driving part, which can improve the driving force of the driving part without adding components, thereby simplifying the design scheme for improving the driving force of the driving part and avoiding complicating the structure of the driving part.

[0014] Another advantage of this application is that it provides a driving device and a camera module, wherein by reasonably arranging the driving components and guide support structure of the driving unit, not only can the driving force of the driving unit be improved, but also the mutual interference between the components of the guide support structure and other components can be avoided.

[0015] Another advantage of this application is that it provides a driving device and a camera module, wherein the driving device avoids the unexpected movement of the driven object during the driving process by arranging the various parts of its elastic members in a specific pattern, thereby reducing the tilt tolerance of the driving device and improving the assembly accuracy of the camera module.

[0100] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0101] Exemplary camera module

[0102] Figure 1 This is a schematic diagram of a camera module according to an embodiment of this application, as shown below. Figure 1 As shown, a camera module according to an embodiment of this application is illustrated, comprising: a photosensitive component 710, an optical lens (not shown in the figure), and a driving component, wherein the optical lens is held on the photosensitive path of the photosensitive component 710 so that the photosensitive component 710 can receive light projected from the optical lens for imaging, and the driving component is used to drive the target object (photosensitive chip 712 and / or optical lens) to move in order to achieve optical focusing and / or optical image stabilization.

[0103] In this embodiment, the photosensitive component 710 includes a circuit board 711, a photosensitive chip 712 electrically connected to the circuit board 711, and a filter element 713 held on the photosensitive path of the photosensitive chip 712. The circuit board 711 forms the mounting substrate of the photosensitive component 710. The circuit board 711 can be implemented as a printed circuit board (PCB), a software-defined board, or a reinforced flexible printed circuit board (PFC). Furthermore, in some examples, a reinforcing plate (not shown) can be provided below the circuit board 711. For example, a steel sheet can be provided below the circuit board 711 to strengthen the circuit board 711 and improve the heat dissipation performance of the photosensitive component 710.

[0104] The circuit board 711 includes a circuit board body, a connecting strip, and a connector portion (wherein the connecting strip and the connector portion are not shown in the figure). The connecting strip portion connects the circuit board body and the connector portion to achieve electrical conduction between the circuit board body and the connector portion.

[0105] The photosensitive chip 712 includes a photosensitive area for receiving imaging light to achieve imaging and a non-photosensitive area surrounding the photosensitive area. The photosensitive chip 712 is electrically connected to the circuit board 711 through photosensitive chip 712 pads located in the non-photosensitive area.

[0106] The specific implementation of the photosensitive chip 712 being electrically connected to the circuit board 711 is not limited to this application. For example, the photosensitive chip 712 can be electrically connected to the circuit board body of the circuit board 711 through wire bonding (gold wire bonding), soldering, flip-chip (FC), redistribution layer (RDL), etc. In the embodiments of this application, the surface of the circuit board 711 facing the optical lens is defined as the front surface of the circuit board 711, and the side opposite to the front surface of the circuit board 711 is defined as the bottom surface or back surface of the circuit board 711. The photosensitive chip 712 can be fixed to the front surface of the circuit board 711 or the back surface of the circuit board 711.

[0107] Accordingly, in some embodiments of this application, the photosensitive chip 712 is fixed to the front side of the circuit board body by an adhesive medium. The circuit board body has a groove or through hole (circuit board through hole) located in its central region, and the photosensitive chip 712 is fixedly installed in the groove or through hole of the circuit board body. That is, the photosensitive chip 712 is housed in the groove or through hole of the circuit board body to make reasonable use of the height space occupied by the circuit board 711, reduce the impact of the thickness of the circuit board 711 on the thickness of the photosensitive component 710, and reduce the height of the camera module.

[0108] A filter element 713, held on the light-sensitive path of the photosensitive chip 712, is used to filter the imaging light entering the photosensitive chip 712. In some embodiments of this application, the photosensitive assembly 710 further includes a filter element holder 714 disposed on the circuit board 711, the filter element 713 being mounted on the filter element holder 714 and corresponding to at least a portion of the light-sensitive area of ​​the photosensitive chip 712, so as to be held on the light-sensitive path of the photosensitive chip 712. Specifically, the filter element 713 can be fixed to the filter element holder 714 by means of upside-down mounting, that is, the filter element 713 is mounted on the side of the filter element holder 714 away from the optical lens, or the filter element 713 can be mounted on the side of the filter element holder 714 closer to the optical lens.

[0109] The method of combining the filter element bracket 714 with the circuit board 711 is not limited to this application. In one specific embodiment of this application, the filter element bracket 714 is formed separately to create a structure independent of the circuit board 711. The filter element bracket 714 is attached to the circuit board 711 with an adhesive and can be used to support other components. In another specific embodiment of this application, the filter element bracket 714 and the circuit board 711 are integrally formed at a predetermined position on the circuit board body through a molding process. In yet another specific embodiment of this application, the filter element bracket 714 is mounted on the circuit board 711 via a molding base. Specifically, the molding base is integrally formed at a predetermined position on the circuit board body through a molding process, and the filter element bracket 714 is fixed to the molding base, thereby mounting the filter element bracket 714 to the circuit board body.

[0110] In some embodiments of this application, the photosensitive assembly 710 further includes an electronic component 715 electrically connected to the circuit board 711. The molding base has a receiving cavity to enclose at least a portion of the circuit board 711 and the electronic component 715 within the receiving cavity, thereby reducing the contamination of the photosensitive chip 712 by dust or other contaminants that may be carried on the surface of the circuit board 711 and / or the electronic component 715. In some embodiments of this application, the molding base not only encloses at least a portion of the circuit board 711 and the electronic component 715 within the receiving cavity, but also encloses at least a portion of the non-photosensitive area of ​​the photosensitive chip 712 within the receiving cavity.

[0111] In other examples of this application, the specific implementation in which the filter element 713 is held on the light-sensing path of the photosensitive chip 712 is not limited to this application. For example, the filter element 713 may be implemented as a filter film and coated on the surface of a certain optical lens of the optical lens to achieve the effect of filtering light.

[0112] In this embodiment, the photosensitive component 710 further includes an electrical connector (not shown in the figure) electrically connected to the circuit board 711 to realize the electrical connection between the camera module and an external device. Specifically, the electrical connector is connected to the connector portion to electrically connect to the circuit board 711.

[0113] In this embodiment, the optical lens includes a lens barrel and at least one optical lens mounted within the lens barrel. The optical lens has an optical axis, and the optical lenses are arranged along the direction defined by the optical axis. Those skilled in the art will understand that the resolving power of the optical lens is proportional to the number of optical lenses within a certain range; that is, the higher the resolving power, the more optical lenses are used. In specific implementations, the optical lens can be implemented as a one-piece lens or a split lens. When the optical lens is implemented as a one-piece lens, it includes a lens barrel in which all the optical lenses are mounted; while when the optical lens is implemented as a split lens, it is assembled from at least two lens units.

[0114] In some embodiments of this application, the driving component is used to drive the optical lens and / or the photosensitive chip 712 to move, thereby achieving optical focusing and / or optical image stabilization. Correspondingly, in some embodiments of this application, the driving component only has a lens driving device, and the driving component drives the optical lens to move through the lens driving device to achieve optical focusing and / or optical image stabilization. In some embodiments of this application, the driving component only has a chip driving device, and the driving component drives the photosensitive chip 712 to move through the chip driving device to achieve optical focusing and / or optical image stabilization. In some embodiments of this application, the driving component has both a lens driving device and a chip driving device, and the driving component achieves optical focusing and / or optical image stabilization by driving the corresponding driven object to move through either the lens driving device or the chip driving device; or, optical focusing and / or optical image stabilization are achieved by driving the optical lens and the photosensitive chip 712 to move through the lens driving device and the chip driving device, respectively.

[0115] In this embodiment, the implementation of optical focusing and optical image stabilization is further illustrated by establishing a spatial coordinate system. The direction set by the optical axis is defined as the Z-axis direction (i.e., the direction set by the Z-axis), a first preset direction perpendicular to the plane containing the optical axis is defined as the X-axis direction (i.e., the direction set by the X-axis), and a second preset direction perpendicular to the plane containing the optical axis is defined as the Y-axis direction (i.e., the direction set by the Y-axis). In this embodiment, the X-axis and Y-axis directions are perpendicular to each other, and the Z-axis direction is perpendicular to the plane containing the X-axis and Y-axis directions. In other words, the X-axis, Y-axis, and Z-axis constitute a three-dimensional Cartesian coordinate system.

[0116] In this embodiment, the driving component can achieve optical focusing by driving the optical lens and / or the photosensitive component 710 to move along the Z-axis, and achieve optical image stabilization by driving the optical lens and / or the photosensitive component 710 to move along the X-axis and Y-axis. Alternatively, the driving component can achieve optical focusing by driving the optical lens and / or the photosensitive component 710 to rotate around the Z-axis, and achieve optical image stabilization by driving the optical lens and / or the photosensitive component 710 to rotate around the X-axis and Y-axis.

[0117] For ease of explanation and understanding, the following uses the lens drive device as an example to illustrate the structure and method for achieving optical focusing and optical image stabilization. The drive device 720 mentioned below specifically refers to the lens drive device.

[0118] like Figures 2 to 4 As shown in this embodiment, the driving device 720 includes a fixed portion 721 having a receiving cavity 7201, a movable portion 722 suspended within the receiving cavity 7201, and a driving portion 723 for driving the movable portion 722 to move relative to the fixed portion 721. The movable portion 722 is adapted to mount an optical lens therein. During the process of the driving portion 723 driving the movable portion 722 to move relative to the fixed portion 721, the optical lens mounted on the movable portion 722 is driven to move along the Z-axis direction or along a plane perpendicular to the Z-axis, thereby realizing the optical focusing and optical image stabilization functions of the camera module.

[0119] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, the fixing part 721 includes an upper cover 7212 and a base 7211 that snap together to form the receiving cavity 7201, which are used to accommodate the movable part 722 and the driving part 723. This not only protects the various components in the driving device 720 from being damaged by impact, but also prevents dust, dirt or stray light from entering the interior of the driving device 720.

[0120] Both the upper cover 7212 and the base 7211 are provided with openings corresponding to the optical lens, so that light reflected by the object can enter the optical lens through the openings provided in the upper cover 7212 and reach the photosensitive component 710.

[0121] like Figures 3 to 5 As shown, the base 7211 includes a base body 72111 and base supports 72112 disposed on the base body 72111. The base supports 72112 extend integrally upwards along the peripheral area of ​​the base body 72111, forming a mounting surface with a height difference between the base supports 72112 and the surface of the base body 72111. The number of base supports 72112 is at least two, and preferably, the base supports 72112 are disposed opposite to each other on the base body 72111, and are centrally symmetrical about the longitudinal central axis of the base body 72111. In a specific example of this application, the base supports 72112 are located at the four corners of the base body 72111, extending integrally upwards along the four corner areas of the base body 72111, and are symmetrically distributed.

[0122] In the embodiments of this application, the specific formation method of the base support column 72112 is not limited to this application. The base support column 72112 can be integrally formed with the base body 72111 through injection molding, or it can be further formed on the already formed base body 72111 through injection molding.

[0123] In this embodiment, the movable part 722 is disposed within the fixed part 721 and can move within the receiving cavity 7201 of the fixed part 721 under the action of the driving part 723. The movable part 722 includes an outer carrier 7222 and an inner carrier 7221 movably mounted on the outer carrier 7222. The inner carrier 7221 is adapted to mount the optical lens therein; in other words, the optical lens is adapted to be mounted on the inner carrier 7221. In this embodiment, the inner carrier 7221 can be driven to move relative to the outer carrier 7222 independently, or it can move together with the outer carrier 7222 under the drive of the outer carrier 7222. Further, by driving the outer carrier 7222 or the inner carrier 7221 to move, the optical lens can be moved to achieve optical focusing or optical image stabilization functions.

[0124] Specifically, in some other embodiments of this application, when the outer carrier 7222 remains stationary and the inner carrier 7221 is driven to move relative to the outer carrier 7222, the inner carrier 7221 can drive the optical lens to move in a direction set along the optical axis to achieve the optical focusing function of the camera module; when the outer carrier 7222 is driven to move relative to the base 7211, the outer carrier 7222 can drive the inner carrier 7221 and the optical lens to move in a plane perpendicular to the optical axis to achieve the optical image stabilization function of the camera module. In other embodiments of this application, when the outer carrier 7222 remains stationary and the inner carrier 7221 is driven to move relative to the outer carrier 7222, the inner carrier 7221 can drive the optical lens to move in a plane perpendicular to the optical axis to achieve the optical image stabilization function of the camera module; when the outer carrier 7222 is driven to move relative to the base 7211, the outer carrier 7222 can drive the inner carrier 7221 and the optical lens to move along the direction set by the optical axis to achieve the optical focusing function of the camera module.

[0125] It is worth mentioning that, in some embodiments of this application, the lens barrel and the inner carrier 7221 of the optical lens have an integrated structure. That is, the inner carrier 7221 not only functions as the lens barrel for accommodating multiple optical lenses, but also acts as a carrier to move the optical lens. Furthermore, the integrated structure of the lens barrel and the inner carrier 7221 can reduce the overall lateral dimension of the driving device 720, thereby reducing the lateral dimension of the camera module.

[0126] like Figures 2 to 7 As shown in the embodiment of this application, the driving device 720 further includes an elastic member 724 disposed in the receiving cavity 7201 of the fixed part 721, which is adapted to drive the movable part 722 back to its original position (i.e., the position when it is not driven by the driving part 723, or the position before it is driven by the driving part 723). The movable part 722 is movably suspended in the receiving cavity 7201 by the elastic member 724.

[0127] The elastic member 724 includes a first elastic component 7241 and a second elastic component 7242 extending between the inner carrier 7221 and the outer carrier 7222. The first elastic component 7241 and the second elastic component 7242 are disposed opposite to each other on opposite sides of the movable portion 722. Figure 5 , Figure 6 and Figure 8As shown. The first elastic component 7241 is located on the light-incident side of the optical lens, and the second elastic component 7242 is located on the light-outceasing side of the optical lens, so as to repositionably suspend the optical lens and the movable part 722 within the receiving cavity 7201 of the fixed part 721.

[0128] Specifically, the first elastic component 7241 has a sheet-like structure and includes a focusing elastic portion 72411 and an image stabilization elastic portion 72412, which extend in a plane perpendicular to the optical axis.

[0129] In some embodiments of this application, optical image stabilization is achieved by driving the inner carrier 7221 to move relative to the outer carrier 7222, and optical focusing is achieved by driving the outer carrier 7222 to move relative to the fixed portion 721. Accordingly, the focusing elastic portion 72411 is disposed on the outer periphery of the image stabilization elastic portion 72412, the image stabilization elastic portion 72412 extending between the inner carrier 7221 and the outer carrier 7222, and the focusing elastic portion 72411 extending between the outer carrier 7222 and the base 7211 of the fixed portion 721. The driving portion 723 is adapted to drive the inner carrier 7221 to move relative to the outer carrier 7222 in a plane perpendicular to the optical axis for optical image stabilization, and the driving portion 723 is adapted to drive the outer carrier 7222 to move the inner carrier 7221, which carries the optical lens, along a direction set by the optical axis for optical focusing.

[0130] In other embodiments of this application, optical focusing is achieved by driving the inner carrier 7221 to move relative to the outer carrier 7222, and optical image stabilization is achieved by driving the outer carrier 7222 to move relative to the fixed portion 721. Accordingly, the image stabilization elastic portion 72412 is disposed on the outer periphery of the focusing elastic portion 72411, the focusing elastic portion 72411 extends between the inner carrier 7221 and the outer carrier 7222, and the image stabilization elastic portion 72412 extends between the outer carrier 7222 and the base 7211 of the fixed portion 721. The driving portion 723 is adapted to drive the inner carrier 7221 to move relative to the outer carrier 7222 along a direction set by the optical axis for optical focusing, and the driving portion 723 is adapted to drive the outer carrier 7222 to move the inner carrier 7221 carrying the optical lens in a plane perpendicular to the optical axis for optical image stabilization.

[0131] When the drive unit 723 drives the inner carrier 7221 to move along the direction set by the optical axis (i.e., the Z-axis direction), the focusing elastic portion 72411 deforms to accumulate elastic force; when the drive unit 723 stops driving, the elastic force of the focusing elastic portion 72411 is released, driving the inner carrier 7221 back to its original position. When the drive unit 723 drives the outer carrier 7222 to move along the X-axis and Y-axis directions in a plane perpendicular to the optical axis, the image stabilization elastic portion 72412 deforms to accumulate elastic force; when the drive unit 723 stops driving, the elastic force of the image stabilization elastic portion 72412 is released, driving the outer carrier 7222 back to its original position.

[0132] It is worth mentioning that, in order to avoid collisions between the inner carrier 7221 and the outer carrier 7222 or the fixing part 721 during the movement of the optical lens, which could lead to deformation or damage of the optical lens and a decrease in image quality, in this embodiment, the inner carrier 7221 is provided with first protrusions for anti-collision on its top and bottom surfaces. Preferably, the first protrusions are made of a material with an elastic modulus lower than that of the inner carrier 7221, such as silicone. The first protrusions can be integrally molded onto the inner carrier 7221 by injection molding or fixed to the inner carrier 7221 by adhesive bonding; this is not limited to this application.

[0133] Similarly, a second protrusion for anti-collision can be provided on the top and bottom surfaces of the outer carrier 7222. The surface of the second protrusion protrudes from the surface of the elastic member 724 to avoid the elastic member 724 from colliding with the base 7211 or the top cover 7212 of the fixing part 721 during the movement of the outer carrier 7222, which would cause damage to the elastic member 724.

[0134] The focusing elastic portion 72411 has a focusing elastic inner contour portion, a focusing elastic outer contour portion, and a focusing elastic deformation portion extending between the focusing elastic inner contour portion and the focusing elastic outer contour portion, wherein the focusing elastic inner contour portion is fixed to the inner carrier 7221, and the focusing elastic outer contour portion is fixed to the outer carrier 7222.

[0135] Accordingly, in a specific example of this application, both the inner carrier 7221 and the outer carrier 7222 have elastic mechanism mounting positions on their top surfaces. The focusing elastic inner contour is fixed to the elastic mechanism mounting position on the top surface of the inner carrier 7221, and the focusing elastic outer contour is fixed to the elastic mechanism mounting position on the top surface of the outer carrier 7222. The focusing elastic deformation portion extends outward from the focusing elastic inner contour to the focusing elastic outer contour, so that the inner carrier 7221 is suspended and disposed within the outer carrier 7222 by the focusing elastic deformation portion. The deformation of the focusing elastic deformation portion reserves a certain amount of movement space for the inner carrier 7221 and provides a certain amount of restoring force for the inner carrier 7221.

[0136] The focusing elastic deformation portion extends bently from the focusing elastic outer contour portion to the focusing elastic inner contour portion, so as to reserve sufficient space for the movement of the inner carrier 7221. This not only ensures the large movement stroke of the inner carrier 7221, but also reduces the driving resistance of the inner carrier 7221 and improves the optical focusing sensitivity of the camera module. It is understood that the longer the focusing elastic deformation portion, the more bends it undergoes, the smaller its deformation after deformation, and the easier it is to return to its original position after being stretched.

[0137] Specifically, in this embodiment, the focusing elastic portion 72411 is arranged in a rotationally symmetrical manner relative to the optical axis. This is because the K-value (elastic coefficient) of the axisymmetrically designed elastic element differs significantly in the X-axis and Y-axis directions, resulting in a larger displacement of the inner carrier 7221 in either the X-axis or Y-axis direction. The rotationally symmetrical elastic element can suppress this displacement. Furthermore, since the elastic coefficient (K-value) of the rotationally symmetrical focusing elastic portion 72411 is consistent in the X-axis and Y-axis directions, when the inner carrier 7221 moves along the Z-axis, the rotationally symmetrical focusing elastic portion 72411 can, to a certain extent, suppress the rotational movement of the inner carrier 7221 around the Z-axis. Even further, the large K-values ​​of the focusing elastic portion 72411 in both the X-axis and Y-axis directions further reduce the amplitude of the rotation of the inner carrier 7221 around the Z-axis. It is understandable that the rotationally symmetrical layout allows the focusing elastic portion 72411 to further improve the flatness of the first elastic component 7241, thereby reducing the tilt tolerance of the driving device 720 and improving the assembly accuracy of the camera module.

[0138] In this embodiment, the focusing elastic portion 72411 includes at least two focusing elastic units distributed in a rotationally symmetrical pattern with respect to the optical axis. The at least two focusing elastic units are independent of each other, that is, the focusing elastic portion 72411 is a split structure, and the number of focusing elastic units is not limited by this application.

[0139] In a specific example of this application, the focusing elastic portion 72411 includes a first focusing elastic unit 7100 and a second focusing elastic unit 7200, wherein the first focusing elastic unit 7100 and the second focusing elastic unit 7200 are rotationally symmetrical with respect to the optical axis, such as... Figure 9 As shown. The first focusing elastic unit 7100 includes a first focusing elastic inner contour portion 7110 fixed to the inner carrier 7221, a first focusing elastic outer contour portion 7130 fixed to the outer carrier 7222, and a first focusing elastic deformation portion 7120 extending between the first focusing elastic inner contour portion 7110 and the first focusing elastic outer contour portion 7130. The second focusing elastic unit 7200 includes a second focusing elastic inner contour portion 7210 fixed to the inner carrier 7221, a second focusing elastic outer contour portion 7230 fixed to the outer carrier 7222, and a second focusing elastic deformation portion 7220 extending between the second focusing elastic inner contour portion 7210 and the second focusing elastic outer contour portion 7230.

[0140] In a specific example of this application, the first focusing elastic inner contour portion 7110 and the second focusing elastic inner contour portion 7210 form a hollow annular structure, such that when the first focusing elastic unit 7100 is fixedly sleeved on the inner carrier 7221, the central region of the annular structure can correspond to the optical lens. The first focusing elastic outer contour portion 7130 and the second focusing elastic outer contour portion 7230 are respectively disposed along opposite sides of the driving device 720. The first focusing elastic deformation portion 7120 and / or the second focusing elastic deformation portion 7220 include a plurality of bent segments extending along the X-axis direction set by the X-axis or the Y-axis direction set by the Y-axis, to provide a certain restoring force for the movement of the inner carrier 7221, wherein each bent segment includes at least two straight segments and a curved segment connecting the two straight segments.

[0141] It is worth mentioning that the focusing elastic deformation part may, but is not limited to, be implemented as at least two spring wires connected between the focusing elastic outer contour part and the focusing elastic inner contour part. When the driving part 723 generates a driving force to drive the inner carrier 7221 to move, the focusing elastic deformation part is driven to generate a reaction damping force that is balanced with the driving force, so that the inner carrier 7221 is stably held at a certain position along the optical axis to realize the optical focusing function of the camera module.

[0142] In this embodiment, the anti-shake elastic portion 72412 has an anti-shake elastic inner contour portion, an anti-shake elastic outer contour portion, and an anti-shake elastic deformation portion extending between the anti-shake elastic inner contour portion and the anti-shake elastic outer contour portion, wherein the anti-shake elastic inner contour portion is fixed to the outer carrier 7222, and the anti-shake elastic outer contour portion is fixed to the base 7211 of the fixing portion 721.

[0143] Accordingly, in a specific example of this application, the top surface of the base support 72112 of the base 7211 is provided with an elastic mechanism mounting position. The anti-shake elastic inner contour is fixed to the elastic mechanism mounting position on the top surface of the outer carrier 7222, and the anti-shake elastic outer contour is fixed to the elastic mechanism mounting position on the top surface of the base support 72112. The anti-shake elastic deformation portion extends outward from the anti-shake elastic inner contour to the anti-shake elastic outer contour, so that the outer carrier 7222 is suspended on the base 7211 by the anti-shake elastic deformation portion. The deformation of the anti-shake elastic deformation portion reserves a certain amount of movement space for the outer carrier 7222 and provides a certain amount of restoring force for the outer carrier 7222.

[0144] The image stabilization elastic deformation portion extends bently from the outer contour of the image stabilization elasticity to the inner contour of the image stabilization elasticity, so as to reserve sufficient space for the movement of the outer carrier 7222. This not only ensures the large movement stroke of the outer carrier 7222, but also reduces the driving resistance of the inner carrier 7221 and improves the optical image stabilization sensitivity of the camera module. It is understood that the longer the length of the image stabilization elastic deformation portion, the more bends it has, the smaller its deformation after deformation, and the easier it is to return to its original position after being stretched.

[0145] Specifically, the anti-shake elastic deformation part includes a plurality of interconnected bent segments extending in the X direction and a plurality of interconnected bent segments extending in the Y direction. The plurality of interconnected bent segments extending in the X direction and the plurality of interconnected bent segments extending in the Y direction are interconnected to generate corresponding restoring forces in the X and Y directions after the anti-shake elastic deformation part is stretched in the X and Y directions, so that the outer carrier 7222 returns to its original position under the action of the anti-shake elastic unit (i.e., the position of the outer carrier 7222 before it is driven to move by the driving part 723).

[0146] In one specific example of this application, one end of a plurality of interconnected bent segments extending along the X direction is connected to the inner contour of the image stabilizing elasticity, and one end of a plurality of interconnected bent segments extending along the Y direction is connected to the outer contour of the image stabilizing elasticity. In another specific example of this application, one end of a plurality of interconnected bent segments extending along the X direction is connected to the outer contour of the image stabilizing elasticity, and one end of a plurality of interconnected bent segments extending along the Y direction is connected to the inner contour of the image stabilizing elasticity. This is not limited to the application itself.

[0147] Specifically, in this embodiment, the image stabilization elastic portion 72412 is arranged in an axisymmetric manner relative to the optical axis. This is because the rotationally symmetrical design of the elastic element results in a smaller K value in the direction of rotation along the Z-axis, which makes it easier for the outer carrier 7222 to generate rotational motion around the Z-axis during translational movement along the X and Y axes. The axisymmetric image stabilization elastic portion 72412 effectively improves the above problem. When the outer carrier 7222 moves along the X and Y axes, the axisymmetric image stabilization elastic portion 72412 can suppress the rotational motion of the outer carrier 7222 around the Z-axis. It is understood that the axisymmetric arrangement allows the image stabilization elastic portion 72412 to further improve the flatness of the first elastic component 7241, thereby reducing the tilt tolerance of the drive device 720 and improving the assembly accuracy of the camera module.

[0148] In this embodiment, the image stabilization elastic portion 72412 includes at least two image stabilization elastic units distributed in an axisymmetric pattern relative to the optical axis. The at least two image stabilization elastic units are independent of each other, that is, the image stabilization elastic portion 72412 is a split structure, and the number of image stabilization elastic units is not limited by this application.

[0149] In a specific example of this application, the number of image stabilization elastic units is 74. Correspondingly, the image stabilization elastic portion 72412 includes four image stabilization elastic units, which are distributed in an axially symmetrical pattern relative to the X and Y axes. Specifically, the image stabilization elastic portion 72412 includes a first image stabilization elastic unit 7300, a second image stabilization elastic unit 7400, a third image stabilization elastic unit 7500, and a fourth image stabilization elastic unit 7600 arranged sequentially in a clockwise direction, as follows... Figure 9 As shown. The first image stabilization elastic unit 7300 and the fourth image stabilization elastic unit 7600 are symmetrically distributed with respect to the X-axis, the second image stabilization elastic unit 7400 and the third image stabilization elastic unit 7500 are symmetrically distributed with respect to the X-axis, the first image stabilization elastic unit 7300 and the second image stabilization elastic unit 7400 are symmetrically distributed with respect to the Y-axis, and the third image stabilization elastic unit 7500 and the fourth image stabilization elastic unit 7600 are symmetrically distributed with respect to the Y-axis. The first image stabilization elastic unit 7300, the second image stabilization elastic unit 7400, the third image stabilization elastic unit 7500 and the fourth image stabilization elastic unit 7600 are arranged in an axially symmetrical pattern.

[0150] The first anti-shake elastic unit 7300, the second anti-shake elastic unit 7400, the third anti-shake elastic unit 7500 and the fourth anti-shake elastic unit 7600 are located at the four corners of the drive device 720, so that the outer carrier 7222 is subjected to more symmetrical forces under the action of the four anti-shake elastic units, thereby enabling the outer carrier 7222 to be stably suspended on the base 7211.

[0151] More specifically, the first stabilization elastic unit 7300 includes a first stabilization elastic inner contour portion 7310 fixed to the outer carrier 7222, a first stabilization elastic outer contour portion 7330 fixed to the base 7211, and a first stabilization elastic deformation portion 7320 integrally connecting the first stabilization elastic inner contour portion 7310 and the first stabilization elastic outer contour portion 7330; the second stabilization elastic unit 7400 includes a second stabilization elastic inner contour portion 7410 fixed to the outer carrier 7222, a second stabilization elastic outer contour portion 7430 fixed to the base 7211, and a second stabilization elastic deformation portion 742 integrally connecting the second stabilization elastic inner contour portion 7410 and the second stabilization elastic outer contour portion 7430. 0; The third anti-shake elastic unit 7500 includes a third anti-shake elastic inner contour portion 7510 fixed to the outer carrier 7222, a third anti-shake elastic outer contour portion 7530 fixed to the base 7211, and a third anti-shake elastic deformation portion 7520 integrally connecting the third anti-shake elastic inner contour portion 7510 and the third anti-shake elastic outer contour portion 7530; The fourth anti-shake elastic unit 7600 includes a fourth anti-shake elastic inner contour portion 7610 fixed to the outer carrier 7222, a fourth anti-shake elastic outer contour portion 7630 fixed to the base 7211, and a fourth anti-shake elastic deformation portion 7620 integrally connecting the fourth anti-shake elastic inner contour portion 7610 and the fourth anti-shake elastic outer contour portion 7630, such as Figure 9 As shown.

[0152] It is worth mentioning that the first focusing elastic outline portion 7130 and the second focusing elastic outline portion 7230 in the two focusing elastic units are respectively arranged on opposite sides of the driving device 720 along the X-axis direction or the Y-axis direction. This arrangement allows the focusing elastic portion 72411 and the image stabilization elastic portion 72412 to make full use of the spatial position of the lens driving device, and avoids interference between the focusing elastic portion 72411 and the image stabilization elastic portion 72412, thereby affecting the driving effect.

[0153] In summary, the first elastic component 7241 includes the focusing elastic portion 72411 and the image stabilization elastic portion 72412. The focusing elastic portion 72411 is arranged in a rotationally symmetrical manner about the Z-axis, and the image stabilization elastic portion 72412 is arranged in an axially symmetrical manner with respect to the X and Y axes. This method prevents unintended movement of the driven object during the movement of the driven object. Specifically, on the one hand, when the driving unit 723 drives the inner carrier 7221 to move along the Z-axis for optical focusing, the focusing elastic portion 72411 can suppress translational movement of the inner carrier 7221 along the X and Y axes, and also suppress rotational movement of the inner carrier 7221 along the Z-axis. On the other hand, when the driving unit 723 drives the outer carrier 7222 to move along the X and Y axes for optical image stabilization, the image stabilization elastic portion 72412 can suppress rotational movement of the outer carrier 7222 about the Z-axis.

[0154] It is worth mentioning that, in some embodiments of this application, the focusing elastic portion 72411 and the image stabilization elastic portion 72412 are completely separate to avoid interference between them, which would affect the driving effect. In other embodiments of this application, at least a portion of the focusing elastic portion 72411 and the image stabilization elastic portion 72412 are interconnected. This simplifies the installation of the driving device 720 and improves the flatness of the first elastic component 7241, thereby reducing the tilt tolerance of the driving device 720 and improving the assembly accuracy of the camera module.

[0155] Accordingly, in some embodiments of this application, the first elastic component 7241 further includes an elastic connecting portion 72413 connecting the focusing elastic portion 72411 and the image stabilization elastic portion 72412. One end of the elastic connecting portion 72413 is connected to the focusing elastic portion 72411, and the other end of the elastic connecting portion 72413 is connected to the image stabilization elastic portion 72412, such as... Figure 9As shown. The elastic connecting portion 72413 includes multiple bent segments along the X-axis or Y-axis direction. The extension direction of the multiple bent segments of the elastic connecting portion 72413 is perpendicular to the extension direction of the bent segments of the adjacent focusing elastic deformation portion. In a specific example of this application, the multiple bent segments of the elastic connecting portion 72413 extend along the X-axis direction, and the bent segments of the adjacent focusing elastic deformation portion extend along the Y-axis direction. This arrangement provides more extension space for the bent segments of the elastic connecting portion 72413 and the focusing elastic deformation portion, allowing for more bent segments to be provided in both. This arrangement also avoids interference between the elastic connecting portion 72413 and the focusing elastic deformation portion.

[0156] In some embodiments of this application, the two focusing elastic units of the focusing elastic portion 72411 are interconnected with at least two image stabilization elastic units of the image stabilization elastic portion 72412, and the elastic connection portion 72413 includes a first elastic connection unit 7700 and a second elastic connection unit 7800, wherein the first elastic connection unit 7700 and the second elastic connection unit 7800 are arranged symmetrically with respect to the Z-axis.

[0157] In a specific example of this application, the first image stabilization elastic unit 7300 is connected to the first focusing elastic unit 7100, the third image stabilization elastic unit 7500 is connected to the second focusing elastic unit 7200, the first elastic connection unit 7700 is disposed between the first image stabilization elastic unit 7300 and the first focusing elastic unit 7100, and the second elastic connection unit 7800 is disposed between the third image stabilization elastic unit 7500 and the second focusing elastic unit 7200.

[0158] In this specific example, one end of the first elastic connection unit 7700 is connected to the first image stabilization elastic inner contour 7310, and the other end of the first elastic connection unit 7700 is connected to the first focusing elastic inner contour 7110; one end of the second elastic connection unit 7800 is connected to the second image stabilization elastic inner contour 7410, and the other end of the second elastic connection unit 7800 is connected to the second focusing elastic inner contour 7210. Through the first elastic connection unit 7700 and the second elastic connection unit 7800, two image stabilization elastic units and two focusing elastic units arranged at opposite angles are interconnected. This arrangement not only simplifies the installation of the first elastic component 7241 but also provides the first elastic component 7241 with circuit conduction functionality, making the circuit conduction of the drive device 720 simpler.

[0159] In another specific example of this application, the elastic connection portion 72413 further includes a third elastic connection unit and a fourth elastic connection unit, which are arranged symmetrically with respect to the Z-axis. The third elastic connection unit is connected between the first focusing elastic unit 7100 and the second image stabilization elastic unit 7400, and the fourth elastic connection unit is connected between the second focusing elastic unit 7200 and the fourth image stabilization elastic unit 7600.

[0160] In a specific example of this application, one end of the third elastic connecting unit is connected to the second image stabilization elastic inner contour 7410, and the other end of the third elastic connecting unit is connected to the first focusing elastic inner contour 7110; one end of the fourth elastic connecting unit is connected to the fourth image stabilization elastic inner contour 7610, and the other end of the fourth elastic connecting unit is connected to the second focusing elastic inner contour 7210. This arrangement divides the first elastic component 7241 into two parts, ensuring good consistency of the first elastic component 7241 and allowing the entire plane of the first elastic component 7241 to be installed in the lens drive device with a small tilt tolerance.

[0161] It is worth mentioning that, in this embodiment, the focusing elastic inner contour portion is fixedly mounted to the top surface of the inner carrier 7221 by adhesive bonding or thermal riveting, and the focusing elastic outer contour portion is fixedly mounted to the top surface of the outer carrier 7222 by adhesive bonding or thermal riveting; the image stabilizing elastic inner contour portion is fixedly mounted to the top surface of the outer carrier 7222 by adhesive bonding or thermal riveting, and the image stabilizing elastic outer contour portion is fixedly mounted to the top surface of the base support 72112 by adhesive bonding or thermal riveting. The top surfaces of the elastic mechanism mounting positions corresponding to the focusing elastic inner contour portion, the focusing elastic outer contour portion, the image stabilizing elastic inner contour portion, and the image stabilizing elastic outer contour portion are on the same plane, so that the first elastic component 7241 can be mounted on a flat mounting plane.

[0162] It is also worth mentioning that, in the embodiments of this application, the focusing elastic portion 72411 and the image stabilization elastic portion 72412 in the first elastic component 7241 are both implemented as springs. The image stabilization function of the optical lens is realized by replacing the traditional suspension wire with the image stabilization elastic portion 72412 implemented as a spring. The image stabilization elastic portion 72412 can generate a force on the object to reset it, so as to ensure that the outer carrier 7222 and the base 7211 maintain a relatively stable state.

[0163] The anti-shake elastic portion 72412, as part of the first elastic component 7241, is disposed on the top of the outer carrier 7222 (or the inner carrier 7221) and the base 7211, extending between and connecting the outer carrier 7222 and the base 7211. This arrangement allows the drive device 720 to be assembled sequentially along the optical axis during assembly, which not only simplifies the assembly of the drive device 720 and saves costs, but also reduces the assembly tolerance of the drive device 720 during assembly, resulting in higher precision of the drive device 720.

[0164] In this embodiment, the second elastic component 7242 has a sheet-like structure. The second elastic component 7242 includes a second elastic inner contour portion 72421 fixed to the inner carrier 7221, a second elastic outer contour portion 72423 fixed to the outer carrier 7222, and a second elastic deformation portion 72422 extending between the second elastic inner contour portion 72421 and the second elastic outer contour portion 72423. Figure 6As shown. The bottom surfaces of the inner carrier 7221 and the outer carrier 7222 are provided with elastic mechanism mounting positions. The second elastic outer contour portion 72423 is fixed to the elastic mechanism mounting position on the bottom surface of the outer carrier 7222, and the second elastic inner contour portion 72421 is fixed to the elastic mechanism mounting position on the bottom surface of the inner carrier 7221. This arrangement causes the inner carrier 7221 to be clamped between the focusing elastic portion 72411 of the first elastic component 7241 and the second elastic component 7242, thereby suspending the inner carrier 7221 within the outer carrier 7222.

[0165] Specifically, the second elastic outer contour portion 72423 and the second elastic inner contour portion 72421 of the second elastic component 7242 can be fixed to the outer carrier 7222 and the inner carrier 7221 by means of, but not limited to, bonding or thermal riveting. The second elastic inner contour portion 72421 forms a hollow annular structure, and the second elastic outer contour portion 72423 is disposed at the four corners of the outer carrier 7222 and connected to the second elastic inner contour portion 72421 through the second elastic deformation portion 72422. In a specific example of this application, the second elastic component 7242 is arranged in a rotationally symmetrical manner around the optical axis.

[0166] It is worth mentioning that, in this embodiment of the application, the first elastic component 7241 and the second elastic component 7242 of the elastic member 724 are respectively fixed to the top and bottom surfaces of the inner carrier 7221 and the outer carrier 7222 to support and limit the movement of the inner carrier 7221 and the outer carrier 7222. This not only helps to improve the structural stability of the driving device 720, but also enables the inner carrier 7221 and the outer carrier 7222 to move within a certain stroke range.

[0167] It is also worth mentioning that, in one specific example of this application, the first elastic component 7241 has a split structure, while the second elastic component 7242 has an integral structure. This ensures that when the second elastic component 7242 is installed on the outer carrier 7222, it maintains good consistency, resulting in smaller installation tolerances across its entire plane. The first elastic component 7241 is used to achieve circuit conduction. In another specific example of this application, both the first elastic component 7241 and the second elastic component 7242 are configured as split structures, allowing both to be used for circuit conduction and simplifying the electrical connection method of the drive device 720.

[0168] In this embodiment, the driving unit 723 can drive the inner carrier 7221 to move independently, or it can drive the inner carrier 7221 and the outer carrier 7222 to move together. The driving unit 723 includes a magnet 7233, a focusing coil 7232, and an image stabilization coil 7231, such as... Figure 7 As shown. In a specific example of this application, the magnet 7233 is disposed on the outer carrier 7222, the focusing coil 7232 is disposed on the inner carrier 7221 and corresponds to the magnet 7233, and the image stabilization coil 7231 is disposed on the fixing part 721 and corresponds to the magnet 7233.

[0169] Specifically, the magnet 7233 and the focusing coil 7232 correspond to each other in a first direction. The focusing coil 7232 interacts with the magnet 7233 to generate electromagnetic force, which drives the inner carrier 7221 to move along the direction set by the optical axis to achieve optical focusing. Figure 3 and Figure 10 As shown, the image stabilization coil 7231 is disposed on the base 7211 of the fixing part 721. The magnet 7233 and the image stabilization coil 7231 correspond to each other in a second direction, wherein the first direction is perpendicular to the second direction. The image stabilization coil 7231 and the magnet 7233 interact to generate an electromagnetic force, which is used to drive the outer carrier 7222 to move in a plane perpendicular to the optical axis, so as to achieve the optical image stabilization function.

[0170] More specifically, the focusing coil 7232 is disposed on the outer side wall of the inner carrier 7221. The specific structure and formation of the focusing coil 7232 are not limited to this application. In one specific example of this application, the focusing coil 7232 is wound in multiple turns and multiple layers around the outer side wall of the inner carrier 7221; in another specific example of this application, the focusing coil 7232 is pre-processed into a hollow planar coil, and the focusing coil 7232 can be flatly attached to the outer side wall of the inner carrier 7221.

[0171] It is worth mentioning that, in the embodiments of this application, such as Figure 14As shown, the outer side wall of the inner carrier 7221 is provided with columnar protrusions 72211, which extend outward from the side wall of the inner carrier 7221. In a specific example of this application, the number of columnar protrusions 72211 is 72, and they are provided on opposite sides of the inner carrier 7221. The end of the focusing coil 7232 can be wound around the columnar protrusions 72211, that is, one end (the starting end) of the focusing coil 7232 is wound around one of the columnar protrusions 72211, the main body of the focusing coil 7232 is wound around the outer periphery of the inner carrier 7221, and the other end (the ending end) of the focusing coil 7232 is wound around another columnar protrusion 72211. In a specific example of this application, the columnar protrusion 72211 has a T-shaped structure, that is, the thickness of the top (outer end) of the columnar protrusion 72211 is thicker than that of other positions, in order to prevent the focusing coil 7232 from falling off during the winding process.

[0172] Specifically, the magnet 7233 and the focusing coil 7232 are disposed opposite to each other on the inner sidewall of the outer carrier 7222. In a specific example of this application, the inner sidewall of the outer carrier 7222 has openings facing the optical axis and facing the photosensitive component 710. The side of the magnet 7233 near the optical axis and the side near the photosensitive component 710 are not blocked by the outer carrier 7222, so that the side of the magnet 7233 near the optical axis can directly face the focusing coil 7232, and the side of the magnet 7233 near the photosensitive component 710 can directly face the image stabilization coil 7231.

[0173] The number of magnets 7233 is at least three, that is, the number of magnets 7233 is greater than or equal to 73. At least one of the three magnets 7233 can interact with the focusing coil 7232 to generate a driving force along the Z-axis direction. At least two of the three magnets 7233 can interact with the image stabilization coil 7231 to generate a driving force along the X-axis direction and the Y-axis direction.

[0174] In one specific example of this application, the number of magnets 7233 is four. The four magnets 7233 can be disposed at the four sides of the outer carrier 7222, or at the four corners of the outer carrier 7222; this is not limited to this application. In this specific example, the side of the magnet 7233 facing the focusing coil 7232 is the N pole, and the side away from the focusing coil 7232 is the S pole.

[0175] In particular, in one embodiment of this application, the magnet 7233 has an asymmetric structure, thereby allowing the direction of the magnetic field of the magnet 7233 to be identified. Specifically, as... Figure 16 As shown, each of the four magnets 7233 has a beveled edge 72331, which extends between two sides and forms an angle with each of the two sides that is not equal to 90 degrees. The beveled edge 72331 is formed only at one corner of the magnet 7233, making the magnet 7233 have an asymmetrical structure. Because the beveled edge 72331 is asymmetrically arranged on the magnet 7233, making the magnet 7233 have an asymmetrical structure, the beveled edge 72331 can indicate the direction of the magnetic field of the magnet 7233, so that the direction of the magnetic field of the magnet 7233 can be easily confirmed during the assembly of the drive device 720, thereby facilitating the assembly of the drive device 720.

[0176] Furthermore, due to the asymmetrical structure of the beveled edge 72331, the magnetic field generated by the magnet 7233 is also asymmetrical, which is detrimental to the stability of the drive device 720. Therefore, in this embodiment, one end of the magnet 7233 with the beveled edge 72331 is designated as the head of the magnet 7233, and the other end of the magnet 7233 without the beveled edge 72331 and opposite to the head is designated as the tail of the magnet 7233. The four magnets 7233 are respectively arranged end-to-end on the four sides of the outer carrier 7222. In other words, the four magnets 7233 are arranged in the same direction around the four sides of the outer carrier 7222. This makes the magnetic field generated by the four magnets 7233 relatively regular, reducing the instability caused by the beveled edge 72331.

[0177] Specifically, the anti-shake coil 7231 is disposed on the upper surface of the base body 72111, and the anti-shake coil 7231 and the magnet 7233 are disposed opposite each other along the second direction (e.g., the height direction). The number of anti-shake coils 7231 is at least two, and the anti-shake coils 7231 and the magnet 7233 interact to generate driving forces along the X-axis and Y-axis directions, thereby driving the outer carrier 7222 to move along the X-axis and Y-axis directions. In a specific example of this application, the number of anti-shake coils 7231 is four, and the four anti-shake coils 7231 are disposed opposite each other to the four magnets 7233. The four anti-shake coils 7231 can be disposed at the four sides of the base body 72111, or at the four corners of the base body 72111; this is not limited to this application.

[0178] In this embodiment, to improve the stability of the drive device 720 during optical image stabilization and thus improve image quality, the drive device 720 further includes a guide support mechanism 725 disposed between the fixed part 721 and the movable part 722. In one specific example of this application, optical image stabilization is achieved by driving the outer carrier 7222 to move. The guide support mechanism 725 is disposed between the outer carrier 7222 and the base body 72111, so that the guide support mechanism 725 can always guide and support the outer carrier 7222 during the movement of the outer carrier 7222 relative to the base 7211, allowing the outer carrier 7222 to move smoothly. In another specific example of this application, optical image stabilization is achieved by driving the inner carrier 7221 to move. The guide support mechanism 725 is disposed between the inner carrier 7221 and the base 7211. This application does not limit this.

[0179] The guide support mechanism 725 is disposed between the base 7211 and the outer carrier 7222 (or the inner carrier 7221), ensuring constant frictional contact between the base 7211 and the guide support mechanism 725, and between the outer carrier 7222 (or the inner carrier 7221) and the guide support mechanism 725. When the anti-shake coil 7231 is energized, the anti-shake coil 7231 interacts with the magnet 7233, driving the outer carrier 7222 (or the inner carrier 7221) to move along the X-axis and Y-axis directions. During this process, the anti-shake elastic part 72412 deforms. When the anti-shake coil 7231 is de-energized, the anti-shake elastic part 72412 returns to its original shape and drives the outer carrier 7222 to reset.

[0180] Specifically, the guide support mechanism 725 is implemented as a mechanism with a track-ball structure. The guide support mechanism 725 includes a track 7251 disposed between the movable part 722 and the fixed part 721, and balls 7252 disposed within the track 7251. Figure 2 and Figure 6 As shown. Since the ball bearing 7252 is set inside the track 7251, the movement trajectory of the ball bearing 7252 is restricted within the track 7251. The ball bearing 7252 can move within the track 7251 according to a preset movement pattern, thereby providing a certain movement space for the movement of the outer carrier 7222.

[0181] More specifically, the track 7251 includes a lower track and an upper track, wherein the lower track is disposed on the top surface of the base body 72111 of the base 7211, and the upper track is disposed on the bottom surface of the outer carrier 7222, the positions of the upper track and the lower track corresponding to each other. The ball bearing 7252 is accommodated between the upper track and the lower track and is allowed to move along the lower track and the upper track, thus the ball bearing 7252 is movably held between the outer carrier 7222 and the base 7211, and assembled between the outer carrier 7222 and the base 7211 in such a way that the outer carrier 7222 is suspended within the base 7211.

[0182] Furthermore, the upper track and the lower track extend perpendicularly to each other, forming a cross shape. The perpendicularity of the lengths of the upper and lower tracks prevents interference when the outer carrier 7222 moves along the X-axis and Y-axis. In one specific example of this application, the upper track extends along the X-axis and the lower track extends along the Y-axis; in another specific example of this application, the upper track extends along the Y-axis and the lower track extends along the X-axis.

[0183] On the same horizontal plane, the upper or lower track has both tracks extending along the X-axis and tracks extending along the Y-axis. That is, the lower track on the top surface of the base body 72111 of the base 7211 has both tracks extending along the X-axis and tracks extending along the Y-axis; the upper track on the bottom surface of the outer carrier 7222 has both tracks extending along the X-axis and tracks extending along the Y-axis. This arrangement prevents the ball bearings from rotating during optical image stabilization, thus avoiding impact on the driving effect. Furthermore, tracks 7251 with different extension directions are located on adjacent sides of the base body 72111 of the base 7211, providing a larger mounting space for the image stabilization coil 7231. Even further, the guide support mechanism 725 is disposed on the side of the base 7211, and the length direction of the track 7251 extends along the direction of the side of the base body 72111.

[0184] The number of tracks 7251 is not limited by this application. In one specific example, the number of tracks 7251 is 74, and each track 7251 contains at least one ball bearing 7252. The 74 tracks 7251 are respectively arranged on the four sides of the base 7211 near the four corners of the base body 72111. The extension directions of two adjacent tracks 7251 are perpendicular to each other. When one of the four tracks 7251 extends along the X-axis, its adjacent track 7251 extends along the Y-axis, and its opposite track extends along the X-axis. Similarly, when one of the four tracks 7251 extends along the Y-axis, its adjacent track extends along the X-axis, and its opposite track extends along the Y-axis. Alternatively, the four tracks are centrally symmetrical about the Z-axis.

[0185] In this embodiment, the driving device 720 further includes an electrical connection member 726, such as... Figure 2 As shown. The electrical connection member 726 is disposed on the base 7211 of the fixing part 721 and electrically connected to the elastic member 724, so as to provide working power to the focusing coil 7232 and the image stabilization coil 7231 through the electrical connection member 726 and the elastic member 724. Figure 11 and Figure 12 As shown, the electrical connection member 726 includes an upper end 7261, a middle part 7262, and a lower end 7263. The upper end 7261, the middle part 7262, and the lower end 7263 are interconnected to achieve an electrical connection with an external power supply device through the electrical connection member 726, thereby providing power to the drive device 720.

[0186] Specifically, in this embodiment, the middle portion 7262 of the electrical connection member 726 is disposed within the base body 72111, and the upper end portion 7261 of the electrical connection member 726 extends integrally upward from the base support 72112 (e.g., Figure 11 and Figure 12 As shown), the lower end 7263 of the electrical connection member 726 extends downward from the base body 72111 (as shown). Figure 13 As shown), it enables electrical communication with electronic devices external to the drive device 720. The middle portion 7262 of the electrical connection member 726 includes a plurality of electrical connection elements, at least one of the plurality of electrical connection elements of the middle portion 7262 of the electrical connection member 726 integrally extends upward to the top of the base support 72112 to form the upper end portion 7261 of the electrical connection member 726; at least one of the plurality of electrical connection elements of the middle portion 7262 of the electrical connection member 726 integrally extends downward from the base body 72111 to form the lower end portion 7263 of the electrical connection member 726.

[0187] Accordingly, in this embodiment, the focusing elastic portion 72411 of the first elastic component 7241 further includes a conductive end, wherein the conductive end extends outward from the inner contour of the focusing elastic portion. In a specific example of this application, there are two conductive ends, the positions of which correspond to the columnar protrusions 72211 of the inner carrier 7221, and the conductive ends are electrically connected to the focusing coil 7232 wound on the columnar protrusions 72211 of the inner carrier 7221.

[0188] The number of upper ends 7261 of the electrical connection member 726 is at least two, and the upper ends 7261 of the at least two electrical connection members 726 are electrically connected to the image stabilization elastic outer contour, so that the electrical energy provided by the external power supply device can pass sequentially through the lower end 7263, the middle part 7262, the upper end 7261, the image stabilization elastic part 72412, and the focusing elastic part 72411 of the electrical connection member 726 to the focusing coil 7232, thereby driving the inner carrier 7221.

[0189] In one specific example of this application, the number of upper ends 7261 of the electrical connection members 726 is four, respectively disposed on the four base supports 72112. In one specific example of this application, only the upper ends 7261 of the four electrical connection members 726 that simultaneously connect the image stabilization elastic portion 72412 and the focusing elastic portion 72411 achieve circuit conduction. Of course, it is understood that all four upper ends 7261 of the electrical connection members 726 can achieve circuit conduction, and this application does not limit this.

[0190] In one specific example of this application, the first elastic component 7241 has a split structure, while the second elastic component 7242 has an integral structure. The two electrical connection points of the focusing coil 7232 are electrically connected to the first elastic component 7241 to achieve electrical conduction of the focusing coil 7232. In another specific example of this application, the first elastic component 7241 and the second elastic component 7242 both have split structures. The two electrical connection points of the focusing coil 7232 can achieve circuit conduction by being electrically connected to either the first elastic component 7241 or the second elastic component 7242. In another specific example of this application, the first elastic component 7241 has an integral structure, the second elastic component 7242 has an integral structure, and the two electrical connection points of the focusing coil 7232 cannot be simultaneously electrically connected to the first elastic component 7241. Therefore, the two electrical connection points of the focusing coil 7232 need to be electrically connected to the first elastic component 7241 and the second elastic component 7242 respectively to realize the electrical conduction of the focusing coil 7232.

[0191] The formation method of the electrical connection member 726 is not limited to this application. In one specific example of this application, the electrical connection member 726 is integrally formed into the base 7211 by an insert injection molding process. That is, the middle part 7262 of the electrical connection member 726 is integrally formed into the base body 72111, the upper end 7261 of the electrical connection member 726 is integrally formed into the base support 72112, and the lower end 7263 of the electrical connection member 726 extends downward from the base body 72111 and is exposed outside the base body 72111. In another specific example of this application, the electrical connection member 726 is formed onto the surface of the base 7211 by attachment.

[0192] In this embodiment of the application, the driving device 720 further includes a magnetically conductive member 727, such as... Figure 12As shown. The magnetically conductive component 727 and the magnet 7233 are arranged opposite each other along a predetermined direction (e.g., the height direction). The formation method of the magnetically conductive component 727 is not limited to this application. In one specific example of this application, the magnetically conductive component 727 is integrally formed on the base body 72111 of the base 7211 by an insert injection molding process; in another specific example of this application, the magnetically conductive component 727 is fixed to the base body 72111 of the base 7211 by adhesive, so that the magnetically conductive component 727 can be opposite to the magnet 7233.

[0193] The magnetically conductive component 727 and the electrical connection component 726 should avoid mutual interference, which can be achieved in various ways. For example, the magnetically conductive component 727 can be disposed at the upper or lower end of the middle portion 7262 of the electrical connection component 726 to avoid interference between them. The magnetically conductive component 727 and the electrical connection component 726 can use different materials to avoid mutual interference. For example, the magnetically conductive component 727 can be made of a magnetically conductive material so that it can generate a magnetic attraction with the magnet 7233, while the electrical connection component 726 can be made of a non-magnetically conductive material that enables signal conduction. This achieves independence between the magnetically conductive function and the electrical connection function of the drive device 720 and simplifies assembly.

[0194] The magnetically conductive component 727 is disposed at the corner of the base 7211, so that one magnetically conductive component 727 can simultaneously correspond to two adjacent magnets 7233. Through the magnetic attraction between the magnetically conductive component 727 and the magnets 7233, the guide support mechanism 725 can always be clamped between the base 7211 and the outer carrier 7222 (or the inner carrier 7221). During the optical image stabilization process, the guide support mechanism 725 can always maintain frictional contact with the base 7211 and the outer carrier 7222 (or the inner carrier 7221). Furthermore, the magnetically conductive component 727 and the magnet 7233 generate a magnetic attraction force along the Z-axis to maintain the stability of the movement of the outer carrier 7222 (or the inner carrier 7221), maintain the centering effect of the outer carrier 7222 (or the inner carrier 7221), and effectively prevent the outer carrier 7222 (or the inner carrier 7221) from falling off due to the shaking or inversion of the camera module.

[0195] In this embodiment, the driving device 720 further includes a position sensing element 728, such as... Figure 10As shown. The position sensing element 728 is disposed opposite to the magnet 7233 on the base 7211. When the outer carrier 7222 moves, the relative position of the position sensing element 728 and the magnet 7233 changes. Based on the strength of the magnetic field of the magnet 7233 sensed by the position sensing element 728, the position of the outer carrier 7222 can be determined, and the current of the anti-shake coil 7231 can be adjusted to move the outer carrier 7222 to the desired position. In this embodiment, the position sensing element 728 can be a Hall element, a driver integrated circuit (driver IC), or a tunneling magnetoresistive (TMR) element.

[0196] The specific location of the position sensing element 728 is not limited to this application. In one specific example, the position sensing element 728 is disposed within the anti-shake coil 7231, and the top surface of the position sensing element 728 is not higher than the top surface of the anti-shake coil 7231. This reduces the height of the drive device 720 and protects the position sensing element 728 from impacts during movement. In another specific example, the position sensing element 728 is disposed on the bottom surface of the base 7211, such as... Figure 13 As shown.

[0197] The position sensing element 728 is electrically connected to the electrical connection member 726. The specific implementation of the electrical connection between the position sensing element 728 and the electrical connection member 726 is not limited to this application. In a specific example of this application, the base body 72111 of the base 7211 has an opening at the location of the position sensing element 728 as a mounting position for the position sensing element 728, allowing the position sensing element 728 to be directly connected to the electrical connection member 726 through this opening. Furthermore, as the height of the mounting position of the position sensing element 728 decreases, the height of the mounting position of the anti-shake coil 7231 can also decrease accordingly. This arrangement not only simplifies the circuit conduction method of the driving device 720 but also further reduces the height of the driving device 720. In summary, the camera module based on the embodiments of this application is explained, wherein the driving device 720 of the camera module is provided with an elastic member 724 including a focusing elastic part 72411 and an image stabilization elastic part 72412. The focusing elastic part 72411 and the image stabilization elastic part 72412 are arranged in a specific pattern to avoid the driven object from moving unexpectedly during the process of driving the driven object to move. In this way, the tilt tolerance of the driving device 720 is reduced and the assembly accuracy of the camera module is improved.

[0198] Figure 17 This is a schematic diagram of a camera module according to an embodiment of this application, as shown below. Figure 17 As shown, a camera module according to an embodiment of this application is illustrated, comprising: a photosensitive component 810, an optical lens (not shown in the figure), and a driving component, wherein the optical lens is held on the light-sensing path of the photosensitive component 810 so that the photosensitive component 810 can receive light projected from the optical lens for imaging, and the driving component is used to drive the target object (photosensitive chip 812 and / or optical lens) to move in order to achieve optical focusing and / or optical image stabilization.

[0199] In this embodiment, the photosensitive component 810 includes a circuit board 811, a photosensitive chip 812 electrically connected to the circuit board 811, and a filter element 813 held on the photosensitive path of the photosensitive chip 812. The circuit board 811 forms the mounting substrate of the photosensitive component 810. The circuit board 811 can be implemented as a printed circuit board (PCB), a software-defined board, or a reinforced flexible printed circuit board (PFC). Furthermore, in some examples, a reinforcing plate (not shown) can be provided below the circuit board 811. For example, a steel sheet can be provided below the circuit board 811 to strengthen the circuit board 811 and improve the heat dissipation performance of the photosensitive component 810.

[0200] The circuit board 811 includes a circuit board body, a connecting strip, and a connector portion (wherein the connecting strip and the connector portion are not shown in the figure). The connecting strip portion connects the circuit board body and the connector portion to achieve electrical conduction between the circuit board body and the connector portion.

[0201] The photosensitive chip 812 includes a photosensitive area for receiving imaging light to achieve imaging and a non-photosensitive area surrounding the photosensitive area. The photosensitive chip 812 is electrically connected to the circuit board 811 through photosensitive chip 812 pads located in the non-photosensitive area.

[0202] The specific implementation of the photosensitive chip 812 being electrically connected to the circuit board 811 is not limited to this application. For example, the photosensitive chip 812 can be electrically connected to the circuit board body of the circuit board 811 through wire bonding (gold wire bonding), soldering, flip-chip (FC), redistribution layer (RDL), etc. In the embodiments of this application, the surface of the circuit board 811 facing the optical lens is defined as the front surface of the circuit board 811, and the side opposite to the front surface of the circuit board 811 is defined as the bottom surface or back surface of the circuit board 811. The photosensitive chip 812 can be fixed to the front surface of the circuit board 811 or the back surface of the circuit board 811.

[0203] Accordingly, in some embodiments of this application, the photosensitive chip 812 is fixed to the front side of the circuit board body by an adhesive medium. The circuit board body has a groove or through hole (circuit board through hole) located in its central region, and the photosensitive chip 812 is fixedly installed in the groove or through hole of the circuit board body. That is, the photosensitive chip 812 is housed in the groove or through hole of the circuit board body to make reasonable use of the height space occupied by the circuit board 811, reduce the impact of the thickness of the circuit board 811 on the thickness of the photosensitive component 810, and reduce the height of the camera module.

[0204] A filter element 813, held on the light-sensitive path of the photosensitive chip 812, is used to filter the imaging light entering the photosensitive chip 812. In some embodiments of this application, the photosensitive assembly 810 further includes a filter element holder 814 disposed on the circuit board 811. The filter element 813 is mounted on the filter element holder 814 and corresponds to at least a portion of the light-sensitive area of ​​the photosensitive chip 812, so as to be held on the light-sensitive path of the photosensitive chip 812. Specifically, the filter element 813 can be fixed to the filter element holder 814 by means of upside-down mounting, that is, the filter element 813 is mounted on the side of the filter element holder 814 away from the optical lens, or the filter element 813 can be mounted on the side of the filter element holder 814 closer to the optical lens.

[0205] The method of combining the filter element bracket 814 with the circuit board 811 is not limited to this application. In one specific embodiment of this application, the filter element bracket 814 is formed separately to create a structure independent of the circuit board 811. The filter element bracket 814 is attached to the circuit board 811 with an adhesive and can be used to support other components. In another specific embodiment of this application, the filter element bracket 814 and the circuit board 811 are integrally formed at a predetermined position on the circuit board body through a molding process. In yet another specific embodiment of this application, the filter element bracket 814 is mounted on the circuit board 811 via a molding base. Specifically, the molding base is integrally formed at a predetermined position on the circuit board body through a molding process, and the filter element bracket 814 is fixed to the molding base, thereby mounting the filter element bracket 814 to the circuit board body.

[0206] In some embodiments of this application, the photosensitive assembly 810 further includes an electronic component 815 electrically connected to the circuit board 811. The molding base has a receiving cavity to enclose at least a portion of the circuit board 811 and the electronic component 815 within the receiving cavity, thereby reducing the contamination of the photosensitive chip 812 by dust or other contaminants that may be carried on the surface of the circuit board 811 and / or the electronic component 815. In some embodiments of this application, the molding base not only encloses at least a portion of the circuit board 811 and the electronic component 815 within the receiving cavity, but also encloses at least a portion of the non-photosensitive area of ​​the photosensitive chip 812 within the receiving cavity.

[0207] In other examples of this application, the specific implementation in which the filter element 813 is held on the light-sensing path of the photosensitive chip 812 is not limited to this application. For example, the filter element 813 may be implemented as a filter film and coated on the surface of a certain optical lens of the optical lens to achieve the effect of filtering light.

[0208] In this embodiment, the photosensitive component 810 further includes an electrical connector (not shown in the figure) electrically connected to the circuit board 811 to realize the electrical connection between the camera module and an external device. Specifically, the electrical connector is connected to the connector portion to electrically connect to the circuit board 811.

[0209] In this embodiment, the optical lens includes a lens barrel and at least one optical lens mounted within the lens barrel. The optical lens has an optical axis, and the optical lenses are arranged along the direction defined by the optical axis. Those skilled in the art will understand that the resolving power of the optical lens is proportional to the number of optical lenses within a certain range; that is, the higher the resolving power, the more optical lenses are used. In specific implementations, the optical lens can be implemented as a one-piece lens or a split lens. When the optical lens is implemented as a one-piece lens, it includes a lens barrel in which all the optical lenses are mounted; while when the optical lens is implemented as a split lens, it is assembled from at least two lens units.

[0210] In some embodiments of this application, the driving component is used to drive the optical lens and / or the photosensitive chip 812 to move, thereby achieving optical focusing and / or optical image stabilization. Correspondingly, in some embodiments of this application, the driving component only has a lens driving device, and the driving component drives the optical lens to move through the lens driving device to achieve optical focusing and / or optical image stabilization. In some embodiments of this application, the driving component only has a chip driving device, and the driving component drives the photosensitive chip 812 to move through the chip driving device to achieve optical focusing and / or optical image stabilization. In some embodiments of this application, the driving component has both a lens driving device and a chip driving device, and the driving component achieves optical focusing and / or optical image stabilization by driving the corresponding driven object to move through either the lens driving device or the chip driving device; or, optical focusing and / or optical image stabilization are achieved by driving the optical lens and the photosensitive chip 812 to move through the lens driving device and the chip driving device, respectively.

[0211] In this embodiment, the implementation of optical focusing and optical image stabilization is further illustrated by establishing a spatial coordinate system. The direction set by the optical axis is defined as the Z-axis direction (i.e., the direction set by the Z-axis), a first preset direction perpendicular to the plane containing the optical axis is defined as the X-axis direction (i.e., the direction set by the X-axis), and a second preset direction perpendicular to the plane containing the optical axis is defined as the Y-axis direction (i.e., the direction set by the Y-axis). In this embodiment, the X-axis and Y-axis directions are perpendicular to each other, and the Z-axis direction is perpendicular to the plane containing the X-axis and Y-axis directions. In other words, the X-axis, Y-axis, and Z-axis constitute a three-dimensional Cartesian coordinate system.

[0212] In this embodiment, the driving component can achieve optical focusing by driving the optical lens and / or the photosensitive component 810 to move along the Z-axis, and achieve optical image stabilization by driving the optical lens and / or the photosensitive component 810 to move along the X-axis and Y-axis. Alternatively, the driving component can achieve optical focusing by driving the optical lens and / or the photosensitive component 810 to rotate around the Z-axis, and achieve optical image stabilization by driving the optical lens and / or the photosensitive component 810 to rotate around the X-axis and Y-axis.

[0213] For ease of explanation and understanding, the following uses the lens drive device as an example to illustrate the structure and method for achieving optical focusing and optical image stabilization. The drive device 820 mentioned below specifically refers to the lens drive device.

[0214] like Figures 18 to 20As shown in this embodiment, the driving device 820 includes a fixed part 821 having a receiving cavity 8201, a movable part 822 suspended within the receiving cavity 8201, and a driving part 823 for driving the movable part 822 to move relative to the fixed part 821. The movable part 822 is adapted to mount an optical lens therein. During the process of the driving part 823 driving the movable part 822 to move relative to the fixed part 821, the optical lens mounted on the movable part 822 is driven to move along the Z-axis direction or along a plane perpendicular to the Z-axis, so as to realize the optical focusing and optical image stabilization functions of the camera module.

[0215] In the embodiments of this application, such as Figure 19 and Figure 20 As shown, the fixing part 821 includes an upper cover 8212 and a base 8211 that snap together to form the receiving cavity 8201, which are used to accommodate the movable part 822 and the driving part 823. This not only protects the various components in the driving device 820 from being damaged by impact, but also prevents dust, dirt or stray light from entering the interior of the driving device 820.

[0216] Both the upper cover 8212 and the base 8211 are provided with openings corresponding to the optical lens, so that light reflected by the object can enter the optical lens through the openings provided in the upper cover 8212 and reach the photosensitive component 810.

[0217] like Figures 19 to 21 As shown, the base 8211 includes a base body 82111 and base supports 82112 disposed on the base body 82111. The base supports 82112 extend integrally upwards along the peripheral area of ​​the base body 82111, forming a mounting surface with a height difference between the base supports 82112 and the surface of the base body 82111. The number of base supports 82112 is at least two, and preferably, the base supports 82112 are disposed opposite to each other on the base body 82111, and are centrally symmetrical about the longitudinal central axis of the base body 82111. In a specific example of this application, the base supports 82112 are located at the four corners of the base body 82111, extending integrally upwards along the four corner areas of the base body 82111, and are symmetrically distributed.

[0218] In this application embodiment, the specific formation method of the base support column 82112 is not limited to this application. The base support column 82112 can be integrally formed with the base body 82111 through injection molding, or it can be further formed on the already formed base body 82111 through injection molding.

[0219] In this embodiment, the movable part 822 is disposed within the fixed part 821 and can move within the receiving cavity 8201 of the fixed part 821 under the action of the driving part 823. The movable part 822 includes an outer carrier 8222 and an inner carrier 8221 movably mounted on the outer carrier 8222. The inner carrier 8221 is adapted to mount the optical lens therein; in other words, the optical lens is adapted to be mounted on the inner carrier 8221. In this embodiment, the inner carrier 8221 can be driven to move relative to the outer carrier 8222 independently, or it can move together with the outer carrier 8222 under the drive of the outer carrier 8222. Further, by driving the outer carrier 8222 or the inner carrier 8221 to move, the optical lens can be moved to achieve optical focusing or optical image stabilization functions.

[0220] Specifically, in some other embodiments of this application, when the outer carrier 8222 remains stationary and the inner carrier 8221 is driven to move relative to the outer carrier 8222, the inner carrier 8221 can drive the optical lens to move in a direction set along the optical axis to achieve the optical focusing function of the camera module; when the outer carrier 8222 is driven to move relative to the base 8211, the outer carrier 8222 can drive the inner carrier 8221 and the optical lens to move in a plane perpendicular to the optical axis to achieve the optical image stabilization function of the camera module. In other embodiments of this application, when the outer carrier 8222 remains stationary and the inner carrier 8221 is driven to move relative to the outer carrier 8222, the inner carrier 8221 can drive the optical lens to move in a plane perpendicular to the optical axis to achieve the optical image stabilization function of the camera module; when the outer carrier 8222 is driven to move relative to the base 8211, the outer carrier 8222 can drive the inner carrier 8221 and the optical lens to move along the direction set by the optical axis to achieve the optical focusing function of the camera module.

[0221] It is worth mentioning that, in some embodiments of this application, the lens barrel and the inner carrier 8221 of the optical lens have an integrated structure. That is, the inner carrier 8221 not only functions as the lens barrel for accommodating multiple optical lenses, but also acts as a carrier to move the optical lens. Furthermore, the integrated structure of the lens barrel and the inner carrier 8221 can reduce the overall lateral dimension of the driving device 820, thereby reducing the lateral dimension of the camera module.

[0222] like Figures 18 to 22 As shown in the embodiment of this application, the driving device 820 further includes an elastic member 824 disposed in the receiving cavity 8201 of the fixed part 821, which is adapted to drive the movable part 822 back to its original position (i.e., the position when it is not driven by the driving part 823, or the position before it is driven by the driving part 823). The movable part 822 is movably suspended in the receiving cavity 8201 by the elastic member 824.

[0223] The elastic member 824 includes a first elastic component 8241 and a second elastic component 8242 extending between the inner carrier 8221 and the outer carrier 8222. The first elastic component 8241 and the second elastic component 8242 are disposed opposite to each other on opposite sides of the movable part 822. Figure 21 and Figure 23 As shown. The first elastic component 8241 is located on the light-incident side of the optical lens, and the second elastic component 8242 is located on the light-outceasing side of the optical lens, so as to repositionably suspend the optical lens and the movable part 822 within the receiving cavity 8201 of the fixed part 821.

[0224] Specifically, the first elastic component 8241 has a sheet-like structure and includes a focusing elastic portion 82411 and an image stabilization elastic portion 82412, which extend in a plane perpendicular to the optical axis.

[0225] In some embodiments of this application, optical image stabilization is achieved by driving the inner carrier 8221 to move relative to the outer carrier 8222, and optical focusing is achieved by driving the outer carrier 8222 to move relative to the fixed part 821. Accordingly, the focusing elastic part 82411 is disposed on the outer periphery of the image stabilization elastic part 82412, the image stabilization elastic part 82412 extends between the inner carrier 8221 and the outer carrier 8222, and the focusing elastic part 82411 extends between the outer carrier 8222 and the base 8211 of the fixed part 821. The driving part 823 is adapted to drive the inner carrier 8221 to move relative to the outer carrier 8222 in a plane perpendicular to the optical axis for optical image stabilization, and the driving part 823 is adapted to drive the outer carrier 8222 to move the inner carrier 8221 carrying the optical lens along the direction set by the optical axis for optical focusing.

[0226] In other embodiments of this application, optical focusing is achieved by driving the inner carrier 8221 to move relative to the outer carrier 8222, and optical image stabilization is achieved by driving the outer carrier 8222 to move relative to the fixed part 821. Accordingly, the image stabilization elastic part 82412 is disposed on the outer periphery of the focusing elastic part 82411, the focusing elastic part 82411 extends between the inner carrier 8221 and the outer carrier 8222, and the image stabilization elastic part 82412 extends between the outer carrier 8222 and the base 8211 of the fixed part 821. The driving part 823 is adapted to drive the inner carrier 8221 to move relative to the outer carrier 8222 along a direction set by the optical axis for optical focusing, and the driving part 823 is adapted to drive the outer carrier 8222 to move the inner carrier 8221 carrying the optical lens in a plane perpendicular to the optical axis for optical image stabilization.

[0227] When the drive unit 823 drives the inner carrier 8221 to move along the direction set by the optical axis (i.e., the Z-axis direction), the focusing elastic portion 82411 deforms to accumulate elastic force; when the drive unit 823 stops driving, the elastic force of the focusing elastic portion 82411 is released, driving the inner carrier 8221 back to its original position. When the drive unit 823 drives the outer carrier 8222 to move along the X-axis and Y-axis directions in a plane perpendicular to the optical axis, the image stabilization elastic portion 82412 deforms to accumulate elastic force; when the drive unit 823 stops driving, the elastic force of the image stabilization elastic portion 82412 is released, driving the outer carrier 8222 back to its original position.

[0228] It is worth mentioning that, in order to avoid collisions between the inner carrier 8221 and the outer carrier 8222 or the fixing part 821 during the movement of the optical lens, which could lead to deformation or damage of the optical lens and a decrease in image quality, in this embodiment, the inner carrier 8221 is provided with first protrusions for anti-collision on its top and bottom surfaces. Preferably, the first protrusions are made of a material with an elastic modulus lower than that of the inner carrier 8221, such as silicone. The first protrusions can be integrally molded onto the inner carrier 8221 by injection molding or fixed to the inner carrier 8221 by adhesive bonding; this is not limited to this application.

[0229] Similarly, a second protrusion for anti-collision can be provided on the top and bottom surfaces of the outer carrier 8222. The surface of the second protrusion protrudes from the surface of the elastic member 824 to avoid the elastic member 824 from colliding with the base 8211 or the top cover 8212 of the fixing part 821 during the movement of the outer carrier 8222, which would cause damage to the elastic member 824.

[0230] The focusing elastic portion 82411 has a focusing elastic inner contour portion, a focusing elastic outer contour portion, and a focusing elastic deformation portion extending between the focusing elastic inner contour portion and the focusing elastic outer contour portion, wherein the focusing elastic inner contour portion is fixed to the inner carrier 8221, and the focusing elastic outer contour portion is fixed to the outer carrier 8222.

[0231] Accordingly, in a specific example of this application, both the inner carrier 8221 and the outer carrier 8222 have elastic mechanism mounting positions on their top surfaces. The focusing elastic inner contour is fixed to the elastic mechanism mounting position on the top surface of the inner carrier 8221, and the focusing elastic outer contour is fixed to the elastic mechanism mounting position on the top surface of the outer carrier 8222. The focusing elastic deformation portion extends outward from the focusing elastic inner contour to the focusing elastic outer contour, so that the inner carrier 8221 is suspended within the outer carrier 8222 by the focusing elastic deformation portion. The deformation of the focusing elastic deformation portion reserves a certain amount of movement space for the inner carrier 8221 and provides a certain amount of restoring force for the inner carrier 8221.

[0232] The focusing elastic deformation portion extends bently from the focusing elastic outer contour portion to the focusing elastic inner contour portion, so as to reserve sufficient space for the movement of the inner carrier 8221. This not only ensures the large movement stroke of the inner carrier 8221, but also reduces the driving resistance of the inner carrier 8221 and improves the optical focusing sensitivity of the camera module. It is understood that the longer the focusing elastic deformation portion, the more bends it has, and the smaller its deformation after deformation, making it easier to return to its original position after being stretched.

[0233] Specifically, in this embodiment, the focusing elastic portion 82411 is arranged in a rotationally symmetrical manner relative to the optical axis. This is because the K-value (elastic coefficient) of the axisymmetrically designed elastic element differs significantly in the X-axis and Y-axis directions, resulting in a larger displacement of the inner carrier 8221 in either the X-axis or Y-axis direction. The rotationally symmetrical elastic element can suppress this displacement. Furthermore, since the elastic coefficient (K-value) of the rotationally symmetrical focusing elastic portion 82411 is consistent in the X-axis and Y-axis directions, when the inner carrier 8221 moves along the Z-axis, the rotationally symmetrical focusing elastic portion 82411 can, to a certain extent, suppress the rotational movement of the inner carrier 8221 around the Z-axis. Even further, the large K-values ​​of the focusing elastic portion 82411 in both the X-axis and Y-axis directions further reduce the amplitude of the rotation of the inner carrier 8221 around the Z-axis. It is understandable that the rotationally symmetrical layout allows the focusing elastic portion 82411 to further improve the flatness of the first elastic component 8241, thereby reducing the tilt tolerance of the driving device 820 and improving the assembly accuracy of the camera module.

[0234] In this embodiment, the focusing elastic portion 82411 includes at least two focusing elastic units distributed in a rotationally symmetrical pattern with respect to the optical axis. The at least two focusing elastic units are independent of each other, that is, the focusing elastic portion 82411 is a split structure, and the number of focusing elastic units is not limited by this application.

[0235] In a specific example of this application, the focusing elastic portion 82411 includes a first focusing elastic unit 8100 and a second focusing elastic unit 8200, wherein the first focusing elastic unit 8100 and the second focusing elastic unit 8200 are rotationally symmetrical with respect to the optical axis, as shown below. Figure 24As shown. The first focusing elastic unit 8100 includes a first focusing elastic inner contour portion 8110 fixed to the inner carrier 8221, a first focusing elastic outer contour portion 8130 fixed to the outer carrier 8222, and a first focusing elastic deformation portion 8120 extending between the first focusing elastic inner contour portion 8110 and the first focusing elastic outer contour portion 8130. The second focusing elastic unit 8200 includes a second focusing elastic inner contour portion 8210 fixed to the inner carrier 8221, a second focusing elastic outer contour portion 8230 fixed to the outer carrier 8222, and a second focusing elastic deformation portion 8220 extending between the second focusing elastic inner contour portion 8210 and the second focusing elastic outer contour portion 8230.

[0236] In a specific example of this application, the first focusing elastic inner contour portion 8110 and the second focusing elastic inner contour portion 8210 form a hollow annular structure, such that when the first focusing elastic unit 8100 is fixedly sleeved on the inner carrier 8221, the central region of the annular structure can correspond to the optical lens. The first focusing elastic outer contour portion 8130 and the second focusing elastic outer contour portion 8230 are respectively disposed along opposite sides of the driving device 820. The first focusing elastic deformation portion 8120 and / or the second focusing elastic deformation portion 8220 include a plurality of bent segments extending along the X-axis direction set by the X-axis or the Y-axis direction set by the Y-axis, to provide a certain restoring force for the movement of the inner carrier 8221, wherein each bent segment includes at least two straight segments and a curved segment connecting the two straight segments.

[0237] It is worth mentioning that the focusing elastic deformation part may, but is not limited to, be implemented as at least two spring wires connected between the focusing elastic outer contour part and the focusing elastic inner contour part. When the driving part 823 generates a driving force to drive the inner carrier 8221 to move, the focusing elastic deformation part is driven to generate a reaction damping force that is balanced with the driving force, so that the inner carrier 8221 is stably held at a certain position along the optical axis to realize the optical focusing function of the camera module.

[0238] In this embodiment, the anti-shake elastic portion 82412 has an anti-shake elastic inner contour portion, an anti-shake elastic outer contour portion, and an anti-shake elastic deformation portion extending between the anti-shake elastic inner contour portion and the anti-shake elastic outer contour portion, wherein the anti-shake elastic inner contour portion is fixed to the outer carrier 8222, and the anti-shake elastic outer contour portion is fixed to the base 8211 of the fixing portion 821.

[0239] Accordingly, in a specific example of this application, the top surface of the base support 82112 of the base 8211 is provided with an elastic mechanism mounting position. The anti-shake elastic inner contour is fixed to the elastic mechanism mounting position on the top surface of the outer carrier 8222, and the anti-shake elastic outer contour is fixed to the elastic mechanism mounting position on the top surface of the base support 82112. The anti-shake elastic deformation part extends outward from the anti-shake elastic inner contour to the anti-shake elastic outer contour, so that the outer carrier 8222 is suspended on the base 8211 by the anti-shake elastic deformation part. The deformation of the anti-shake elastic deformation part reserves a certain amount of movement space for the outer carrier 8222 and provides a certain amount of restoring force for the outer carrier 8222.

[0240] The image stabilization elastic deformation portion extends bently from the outer contour of the image stabilization elasticity to the inner contour of the image stabilization elasticity, so as to reserve sufficient space for the movement of the outer carrier 8222. This not only ensures the large movement stroke of the outer carrier 8222, but also reduces the driving resistance of the inner carrier 8221 and improves the optical image stabilization sensitivity of the camera module. It is understood that the longer the length of the image stabilization elastic deformation portion, the more bends it has, the smaller its deformation after deformation, and the easier it is to return to its original position after being stretched.

[0241] Specifically, the anti-shake elastic deformation part includes a plurality of interconnected bent segments extending in the X direction and a plurality of interconnected bent segments extending in the Y direction. The plurality of interconnected bent segments extending in the X direction and the plurality of interconnected bent segments extending in the Y direction are interconnected to generate corresponding restoring forces in the X and Y directions after the anti-shake elastic deformation part is stretched in the X and Y directions, so that the outer carrier 8222 returns to its original position under the action of the anti-shake elastic unit (i.e., the position of the outer carrier 8222 before it is driven to move by the driving part 823).

[0242] In one specific example of this application, one end of a plurality of interconnected bent segments extending along the X direction is connected to the inner contour of the image stabilizing elasticity, and one end of a plurality of interconnected bent segments extending along the Y direction is connected to the outer contour of the image stabilizing elasticity. In another specific example of this application, one end of a plurality of interconnected bent segments extending along the X direction is connected to the outer contour of the image stabilizing elasticity, and one end of a plurality of interconnected bent segments extending along the Y direction is connected to the inner contour of the image stabilizing elasticity. This is not limited to the application itself.

[0243] Specifically, in this embodiment, the image stabilization elastic portion 82412 is arranged in an axisymmetric manner relative to the optical axis. This is because the rotationally symmetrical design of the elastic element results in a smaller K value in the direction of rotation along the Z-axis, which makes it easier for the outer carrier 8222 to generate rotational motion around the Z-axis during translational movement along the X and Y axes. The axisymmetric image stabilization elastic portion 82412 effectively improves the above problem. When the outer carrier 8222 moves along the X and Y axes, the axisymmetric image stabilization elastic portion 82412 can suppress the rotational motion of the outer carrier 8222 around the Z-axis. It is understood that the axisymmetric arrangement allows the image stabilization elastic portion 82412 to further improve the flatness of the first elastic component 8241, thereby reducing the tilt tolerance of the drive device 820 and improving the assembly accuracy of the camera module.

[0244] In this embodiment, the image stabilization elastic portion 82412 includes at least two image stabilization elastic units distributed in an axisymmetric pattern relative to the optical axis. The at least two image stabilization elastic units are independent of each other, that is, the image stabilization elastic portion 82412 is a split structure, and the number of image stabilization elastic units is not limited by this application.

[0245] In a specific example of this application, the number of image stabilization elastic units is 84. Correspondingly, the image stabilization elastic portion 82412 includes a first image stabilization elastic unit 8300, a second image stabilization elastic unit 8400, a third image stabilization elastic unit 8500, and a fourth image stabilization elastic unit 8600 arranged sequentially in a clockwise direction, as follows: Figure 24 As shown. The first image stabilization elastic unit 8300 and the fourth image stabilization elastic unit 8600 are symmetrically distributed with respect to the X-axis, the second image stabilization elastic unit 8400 and the third image stabilization elastic unit 8500 are symmetrically distributed with respect to the X-axis, the first image stabilization elastic unit 8300 and the second image stabilization elastic unit 8400 are symmetrically distributed with respect to the Y-axis, and the third image stabilization elastic unit 8500 and the fourth image stabilization elastic unit 8600 are symmetrically distributed with respect to the Y-axis. The first image stabilization elastic unit 8300, the second image stabilization elastic unit 8400, the third image stabilization elastic unit 8500 and the fourth image stabilization elastic unit 8600 are arranged in an axially symmetrical pattern.

[0246] The first anti-shake elastic unit 8300, the second anti-shake elastic unit 8400, the third anti-shake elastic unit 8500 and the fourth anti-shake elastic unit 8600 are located at the four corners of the driving device 820, so that the outer carrier 8222 is subjected to more symmetrical forces under the action of the four anti-shake elastic units, thereby enabling the outer carrier 8222 to be stably suspended on the base 8211.

[0247] More specifically, the first stabilization elastic unit 8300 includes a first stabilization elastic inner contour portion 8310 fixed to the outer carrier 8222, a first stabilization elastic outer contour portion 8330 fixed to the base 8211, and a first stabilization elastic deformation portion 8320 integrally connecting the first stabilization elastic inner contour portion 8310 and the first stabilization elastic outer contour portion 8330; the second stabilization elastic unit 8400 includes a second stabilization elastic inner contour portion 8410 fixed to the outer carrier 8222, a second stabilization elastic outer contour portion 8430 fixed to the base 8211, and a second stabilization elastic deformation portion 842 integrally connecting the second stabilization elastic inner contour portion 8410 and the second stabilization elastic outer contour portion 8430. 0; The third anti-shake elastic unit 8500 includes a third anti-shake elastic inner contour portion 8510 fixed to the outer carrier 8222, a third anti-shake elastic outer contour portion 8530 fixed to the base 8211, and a third anti-shake elastic deformation portion 8520 integrally connecting the third anti-shake elastic inner contour portion 8510 and the third anti-shake elastic outer contour portion 8530; The fourth anti-shake elastic unit 8600 includes a fourth anti-shake elastic inner contour portion 8610 fixed to the outer carrier 8222, a fourth anti-shake elastic outer contour portion 8630 fixed to the base 8211, and a fourth anti-shake elastic deformation portion 8620 integrally connecting the fourth anti-shake elastic inner contour portion 8610 and the fourth anti-shake elastic outer contour portion 8630, such as Figure 24 As shown.

[0248] It is worth mentioning that the first focusing elastic outline portion 8130 and the second focusing elastic outline portion 8230 in the two focusing elastic units are respectively arranged on opposite sides of the driving device 820 along the X-axis direction or the Y-axis direction. This arrangement allows the focusing elastic portion 82411 and the image stabilization elastic portion 82412 to make full use of the spatial position of the lens driving device, and avoids interference between the focusing elastic portion 82411 and the image stabilization elastic portion 82412, thereby affecting the driving effect.

[0249] In summary, the first elastic component 8241 includes the focusing elastic portion 82411 and the image stabilization elastic portion 82412. The focusing elastic portion 82411 is arranged in a rotationally symmetrical manner about the Z-axis, and the image stabilization elastic portion 82412 is arranged in an axially symmetrical manner with respect to the X and Y axes. This method prevents unintended movement of the driven object during the movement of the driven object. Specifically, on the one hand, when the driving unit 823 drives the inner carrier 8221 to move along the Z-axis for optical focusing, the focusing elastic portion 82411 can suppress translational movement of the inner carrier 8221 along the X and Y axes, and also suppress rotational movement of the inner carrier 8221 along the Z-axis. On the other hand, when the driving unit 823 drives the outer carrier 8222 to move along the X and Y axes for optical image stabilization, the image stabilization elastic portion 82412 can suppress rotational movement of the outer carrier 8222 about the Z-axis.

[0250] It is worth mentioning that, in some embodiments of this application, the focusing elastic portion 82411 and the image stabilization elastic portion 82412 are completely separate to avoid interference between them, which would affect the driving effect. In other embodiments of this application, at least a portion of the focusing elastic portion 82411 and the image stabilization elastic portion 82412 are interconnected. This simplifies the installation of the driving device 820 and improves the flatness of the first elastic component 8241, thereby reducing the tilt tolerance of the driving device 820 and improving the assembly accuracy of the camera module.

[0251] Accordingly, in some embodiments of this application, the first elastic component 8241 further includes an elastic connecting portion 82413 connecting the focusing elastic portion 82411 and the image stabilization elastic portion 82412. One end of the elastic connecting portion 82413 is connected to the focusing elastic portion 82411, and the other end of the elastic connecting portion 82413 is connected to the image stabilization elastic portion 82412, such as... Figure 24As shown. The elastic connecting portion 82413 includes multiple bent segments along the X-axis or Y-axis direction. The extension direction of the multiple bent segments of the elastic connecting portion 82413 is perpendicular to the extension direction of the bent segments of the adjacent focusing elastic deformation portion. In a specific example of this application, the multiple bent segments of the elastic connecting portion 82413 extend along the X-axis direction, and the bent segments of the adjacent focusing elastic deformation portion extend along the Y-axis direction. This arrangement provides more extension space for the bent segments of the elastic connecting portion 82413 and the focusing elastic deformation portion, allowing for more bent segments to be provided in both. This arrangement also avoids interference between the elastic connecting portion 82413 and the focusing elastic deformation portion.

[0252] In some embodiments of this application, the two focusing elastic units of the focusing elastic portion 82411 are interconnected with at least two image stabilization elastic units of the image stabilization elastic portion 82412, and the elastic connection portion 82413 includes a first elastic connection unit 8700 and a second elastic connection unit 8800, wherein the first elastic connection unit 8700 and the second elastic connection unit 8800 are arranged symmetrically with respect to the Z-axis.

[0253] In a specific example of this application, the first image stabilization elastic unit 8300 is connected to the first focusing elastic unit 8100, the third image stabilization elastic unit 8500 is connected to the second focusing elastic unit 8200, the first elastic connection unit 8700 is disposed between the first image stabilization elastic unit 8300 and the first focusing elastic unit 8100, and the second elastic connection unit 8800 is disposed between the third image stabilization elastic unit 8500 and the second focusing elastic unit 8200.

[0254] In this specific example, one end of the first elastic connection unit 8700 is connected to the first image stabilization elastic inner contour portion 8310, and the other end of the first elastic connection unit 8700 is connected to the first focusing elastic inner contour portion 8110; one end of the second elastic connection unit 8800 is connected to the second image stabilization elastic inner contour portion 8410, and the other end of the second elastic connection unit 8800 is connected to the second focusing elastic inner contour portion 8210. Through the first elastic connection unit 8700 and the second elastic connection unit 8800, two image stabilization elastic units and two focusing elastic units arranged at opposite angles are interconnected. This arrangement not only simplifies the installation of the first elastic component 8241 but also provides the first elastic component 8241 with circuit conduction functionality, making the circuit conduction of the drive device 820 simpler.

[0255] In another specific example of this application, the elastic connection portion 82413 further includes a third elastic connection unit and a fourth elastic connection unit, which are arranged symmetrically about the Z-axis. The third elastic connection unit is connected between the first focusing elastic unit 8100 and the second image stabilization elastic unit 8400, and the fourth elastic connection unit is connected between the second focusing elastic unit 8200 and the fourth image stabilization elastic unit 8600.

[0256] In a specific example of this application, one end of the third elastic connecting unit is connected to the second image stabilization elastic inner contour 8410, and the other end of the third elastic connecting unit is connected to the first focusing elastic inner contour 8110; one end of the fourth elastic connecting unit is connected to the fourth image stabilization elastic inner contour 8610, and the other end of the fourth elastic connecting unit is connected to the second focusing elastic inner contour 8210. This arrangement divides the first elastic component 8241 into two parts, ensuring good consistency of the first elastic component 8241 and allowing the entire plane of the first elastic component 8241 to be installed in the lens drive device with a small tilt tolerance.

[0257] It is worth mentioning that, in this embodiment, the focusing elastic inner contour portion is fixedly mounted to the top surface of the inner carrier 8221 by adhesive bonding or thermal riveting, and the focusing elastic outer contour portion is fixedly mounted to the top surface of the outer carrier 8222 by adhesive bonding or thermal riveting; the image stabilizing elastic inner contour portion is fixedly mounted to the top surface of the outer carrier 8222 by adhesive bonding or thermal riveting, and the image stabilizing elastic outer contour portion is fixedly mounted to the top surface of the base support 82112 by adhesive bonding or thermal riveting. The top surfaces of the elastic mechanism mounting positions corresponding to the focusing elastic inner contour portion, the focusing elastic outer contour portion, the image stabilizing elastic inner contour portion, and the image stabilizing elastic outer contour portion are on the same plane, so that the first elastic component 8241 can be mounted on a flat mounting plane.

[0258] It is also worth mentioning that, in the embodiments of this application, the focusing elastic portion 82411 and the image stabilization elastic portion 82412 in the first elastic component 8241 are both implemented as springs. The image stabilization function of the optical lens is realized by replacing the traditional suspension wire with the image stabilization elastic portion 82412 implemented as a spring. The image stabilization elastic portion 82412 can generate a force on the object to be acted upon, so as to ensure that the outer carrier 8222 and the base 8211 maintain a relatively stable state.

[0259] The anti-shake elastic portion 82412, as part of the first elastic component 8241, is disposed on the top of the outer carrier 8222 (or the inner carrier 8221) and the base 8211, extending between and connecting the outer carrier 8222 and the base 8211. This arrangement allows the drive device 820 to be assembled sequentially along the optical axis during assembly, which not only simplifies the assembly of the drive device 820 and saves costs, but also reduces the assembly tolerance of the drive device 820 during assembly, resulting in higher precision of the drive device 820.

[0260] In this embodiment, the second elastic component 8242 has a sheet-like structure. The second elastic component 8242 includes a second elastic inner contour portion 82421 fixed to the inner carrier 8221, a second elastic outer contour portion 82423 fixed to the outer carrier 8222, and a second elastic deformation portion 82422 extending between the second elastic inner contour portion 82421 and the second elastic outer contour portion 82423. Figure 25As shown. The bottom surfaces of the inner carrier 8221 and the outer carrier 8222 are provided with elastic mechanism mounting positions. The second elastic outer contour portion 82423 is fixed to the elastic mechanism mounting position on the bottom surface of the outer carrier 8222, and the second elastic inner contour portion 82421 is fixed to the elastic mechanism mounting position on the bottom surface of the inner carrier 8221. This arrangement causes the inner carrier 8221 to be clamped between the focusing elastic portion 82411 of the first elastic component 8241 and the second elastic component 8242, thereby suspending the inner carrier 8221 within the outer carrier 8222.

[0261] Specifically, the second elastic outer contour portion 82423 and the second elastic inner contour portion 82421 of the second elastic component 8242 can be fixed to the outer carrier 8222 and the inner carrier 8221 by means of, but not limited to, bonding or thermal riveting. The second elastic inner contour portion 82421 forms a hollow annular structure, and the second elastic outer contour portion 82423 is disposed at the four corners of the outer carrier 8222, and is connected to the second elastic inner contour portion 82421 through the second elastic deformation portion 82422. In a specific example of this application, the second elastic component 8242 is arranged in a rotationally symmetrical manner around the optical axis.

[0262] It is worth mentioning that, in this embodiment of the application, the first elastic component 8241 and the second elastic component 8242 of the elastic member 824 are respectively fixed to the top and bottom surfaces of the inner carrier 8221 and the outer carrier 8222 to support and limit the movement of the inner carrier 8221 and the outer carrier 8222. This not only helps to improve the structural stability of the driving device 820, but also enables the inner carrier 8221 and the outer carrier 8222 to move within a certain stroke range.

[0263] It is also worth mentioning that, in one specific example of this application, the first elastic component 8241 has a split structure, while the second elastic component 8242 has an integral structure. This ensures that when the second elastic component 8242 is installed on the outer carrier 8222, it maintains good consistency, resulting in smaller installation tolerances across its entire plane. The first elastic component 8241 is used to achieve circuit conduction. In another specific example of this application, both the first elastic component 8241 and the second elastic component 8242 are configured as split structures, allowing both to be used for circuit conduction and simplifying the electrical connection method of the driving device 820.

[0264] In this embodiment, the driving unit 823 can drive the inner carrier 8221 to move independently, or it can drive the inner carrier 8221 and the outer carrier 8222 to move together. The driving unit 823 includes at least one magnet 8233, at least one first coil 8231, and at least one second coil 8232, such as... Figure 22 As shown. In a specific example of this application, the magnet 8233 is disposed on the outer carrier 8222, the first coil 8231 is disposed on the fixing part 821 and corresponds to the magnet 8233, and the second coil 8232 is disposed on the inner carrier 8221 and corresponds to the magnet 8233.

[0265] The second coil 8232 is adapted to drive the inner carrier 8221 to move relative to the outer carrier 8222 along the direction set by the optical axis for optical focusing. Specifically, the magnet 8233 and the second coil 8232 correspond to each other in a first direction, and the second coil 8232 interacts with the magnet 8233 to generate an electromagnetic force to drive the inner carrier 8221 to move along the direction set by the optical axis to achieve the optical focusing function.

[0266] The first coil 8231 is adapted to drive the outer carrier 8222 to move the inner carrier 8221, which carries the optical lens, in a plane perpendicular to the optical axis for optical image stabilization. Specifically, as... Figure 19 and Figure 26 As shown, the first coil 8231 is disposed on the base 8211 of the fixing part 821. The magnet 8233 and the first coil 8231 correspond to each other in a second direction, wherein the first direction is perpendicular to the second direction. The first coil 8231 and the magnet 8233 interact to generate electromagnetic force to drive the outer carrier 8222 to move in a plane perpendicular to the optical axis, so as to realize the optical image stabilization function.

[0267] It is worth mentioning that, in the embodiments of this application, the driving device mainly increases the placement space of the driving components by reasonably arranging the driving components (e.g., the first coil 8231) of the driving part 823 and the guide support structure 825 which plays a supporting and guiding role as described below. This can increase the driving force of the driving part 823 without adding components, thereby simplifying the design scheme for increasing the driving force of the driving part 823 and avoiding complicating the structure of the driving part 823.

[0268] In this embodiment, the first coil 8231 extends along the direction set by the edge of the fixing part 821 on the fixing part 821, and the extension direction of the guide support structure 825 on the fixing part is consistent with the extension direction of the first coil 8231. This arrangement can provide a larger placement space for the first coil 8231, so that the first coil 8231 can be designed to be as large as possible, so as to generate a greater driving force during the interaction between the first coil 8231 and the magnet 8233.

[0269] In a specific example of this application, the first coil 8231 is located on the side of the fixing part 821. Specifically, the first coil 8231 is disposed on the base 8211, the base 8211 having a first side 8202, a second side 8203, a third side 8204, and a fourth side 8205 that mutually enclose a rectangle, as shown below. Figure 26 As shown. The first side 8202 and the third side 8204 extend along the X-axis direction set by the X-axis, and the second side 8203 and the fourth side 8205 extend along the Y-axis direction set by the Y-axis.

[0270] The number of first coils 8231 is at least two. The first coils 8231 interact with the magnets 8233 to generate driving forces along the X-axis and Y-axis, thereby driving the outer carrier 8222 to move along the X-axis and Y-axis. In a specific example of this application, the number of first coils 8231 is four. The four first coils 8231 are arranged opposite to the four magnets 8233, and the four first coils 8231 are arranged on the four sides of the base body 82111.

[0271] Accordingly, at least one first coil 8231 includes four first coils 8231, which are located on the first side 8202, the second side 8203, the third side 8204 and the fourth side 8205 respectively and extend along the first side 8202, the second side 8203, the third side 8204 and the fourth side 8205 respectively.

[0272] The second coil 8232 is disposed on the outer side wall of the inner carrier 8221. The specific structure and formation of the second coil 8232 are not limited to this application. In one specific example of this application, the second coil 8232 is wound in multiple turns and multiple layers on the outer side wall of the inner carrier 8221; in another specific example of this application, the second coil 8232 is pre-processed into a hollow planar coil, and the second coil 8232 can be flatly attached to the outer side wall of the inner carrier 8221.

[0273] It is worth mentioning that, in the embodiments of this application, such as Figure 30 As shown, the outer wall of the inner carrier 8221 is provided with columnar protrusions 82211, which extend outward from the side wall of the inner carrier 8221. In a specific example of this application, the number of columnar protrusions 82211 is 82, and they are provided on opposite sides of the inner carrier 8221. The end of the second coil 8232 can be wound around the columnar protrusions 82211, that is, one end (the starting end) of the second coil 8232 is wound around one of the columnar protrusions 82211, the main body of the second coil 8232 is wound around the outer periphery of the inner carrier 8221, and the other end (the ending end) of the second coil 8232 is wound around another columnar protrusion 82211. In a specific example of this application, the columnar protrusion 82211 has a T-shaped structure, that is, the top (outer end) of the columnar protrusion 82211 is thicker than the other parts, in order to prevent the second coil 8232 from falling off during the winding process.

[0274] Specifically, the magnet 8233 and the second coil 8232 are disposed opposite to each other on the inner sidewall of the outer carrier 8222. In a specific example of this application, the inner sidewall of the outer carrier 8222 has openings facing the optical axis and facing the photosensitive component 810. The side of the magnet 8233 near the optical axis and the side near the photosensitive component 810 are not blocked by the outer carrier 8222, so that the side of the magnet 8233 near the optical axis can directly face the second coil 8232, and the side of the magnet 8233 near the photosensitive component 810 can directly face the first coil 8231.

[0275] The number of magnets 8233 is at least three, that is, the number of magnets 8233 is greater than or equal to 83. At least one of the three magnets 8233 can interact with the second coil 8232 to generate a driving force along the Z-axis direction. At least two of the three magnets 8233 can interact with the first coil 8231 to generate a driving force along the X-axis direction and the Y-axis direction.

[0276] In one specific example of this application, the number of magnets 8233 is four. The four magnets 8233 can be disposed at the four sides of the outer carrier 8222, or at the four corners of the outer carrier 8222; this is not limited to this application. In this specific example, the side of the magnet 8233 facing the second coil 8232 is the N pole, and the side away from the second coil 8232 is the S pole.

[0277] In this embodiment, to improve the stability of the drive device 820 during optical image stabilization and enhance image quality, the drive device 820 further includes a guide support structure 825 disposed between the fixed part 821 and the movable part 822. In one specific example of this application, optical image stabilization is achieved by driving the outer carrier 8222 to move. The guide support structure 825 is disposed between the outer carrier 8222 and the base body 82111, so that the guide support structure 825 can always guide and support the outer carrier 8222 during its movement relative to the base 8211, allowing the outer carrier 8222 to move smoothly. In another specific example of this application, optical image stabilization is achieved by driving the inner carrier 8221 to move. The guide support structure 825 is disposed between the inner carrier 8221 and the base 8211. This application does not limit this specific embodiment.

[0278] The guide support structure 825 is disposed between the base 8211 and the outer carrier 8222 (or the inner carrier 8221), ensuring constant frictional contact between the base 8211 and the guide support structure 825, and between the outer carrier 8222 (or the inner carrier 8221) and the guide support structure 825. When the first coil 8231 is energized, the first coil 8231 interacts with the magnet 8233, driving the outer carrier 8222 (or the inner carrier 8221) to move along the X-axis and Y-axis directions. During this process, the anti-shake elastic part 82412 deforms. When the first coil 8231 is de-energized, the anti-shake elastic part 82412 returns to its original shape and drives the outer carrier 8222 to reset.

[0279] Specifically, the guide support structure 825 is implemented as a mechanism with a track-ball bearing structure. The guide support structure 825 includes a track disposed between the movable part 822 and the fixed part 821, and balls disposed within the track, such as... Figure 18 and Figure 25 As shown. Since the balls are set inside the track, the movement trajectory of the balls is restricted within the track. The balls can move within the track according to a preset movement pattern, thus providing a certain amount of movement space for the movement of the outer carrier 8222.

[0280] More specifically, the track includes a lower track and an upper track, wherein the lower track is disposed on the top surface of the base body 82111 of the base 8211, and the upper track is disposed on the bottom surface of the outer carrier 8222, the positions of the upper track and the lower track corresponding to each other. The ball bearing is accommodated between the upper track and the lower track and is allowed to move along the lower track and the upper track, thus the ball bearing is movably held between the outer carrier 8222 and the base 8211, and assembled between the outer carrier 8222 and the base 8211 in such a way that the outer carrier 8222 is suspended within the base 8211.

[0281] In this embodiment of the application, the guide support structure 825 includes a first guide support unit 8251, a second guide support unit 8252, a third guide support unit 8253 and a fourth guide support unit 8254, which are respectively corresponding to the four first coils. The first guide support unit 8251 includes a first lower rail 82511 recessed in the first side 8202 of the base 8211, a first upper rail 82512 recessed in the outer carrier and corresponding to the first lower rail 82511, and at least one first ball bearing 82513 mounted between the first upper rail 82512 and the first lower rail 82511; the second guide support unit 8252 includes a second lower rail 82521 recessed in the second side 8203 of the base 8211, a second upper rail 82522 recessed in the outer carrier and corresponding to the second lower rail 82521, and at least one second ball bearing 82523 mounted between the second upper rail 82522 and the second lower rail 82521; The third guide support unit 8253 includes a third lower track 82531 recessed in the third side 8204 of the base 8211, a third upper track 82532 recessed in the outer carrier and corresponding to the third lower track 82531, and at least one third ball bearing 82533 mounted between the third upper track 82532 and the third lower track 82531; the fourth guide support unit 8254 includes a fourth lower track 82541 recessed in the fourth side 8205 of the base 8211, a fourth upper track 82542 recessed in the outer carrier and corresponding to the fourth lower track 82541, and at least one fourth ball bearing 82543 mounted between the fourth upper track 82542 and the fourth lower track 82541.

[0282] It is worth mentioning that the guide support structure 825 of the drive device cooperates with the first coil 8231 of the drive part 823. By reasonably arranging the drive components of the drive part 823, not only can the driving force of the drive part 823 be improved, but also the mutual interference between the components of the guide support structure 825 and other components can be avoided.

[0283] Specifically, the first coil and the track, which extend in the same direction, are disposed on the same side of the base 8211 along that direction. For example, the first coil extending in the X-axis direction and its corresponding track are both disposed on the X-axis side of the base 8211, and the first coil extending in the Y-axis direction and its corresponding track are both disposed on the Y-axis side of the base 8211. This avoids the track extending inward and interfering with the second elastic component.

[0284] In this embodiment, the extension direction of the lower track of each guide support unit of the guide support structure 825 is consistent with the extension direction of the corresponding first coil 8231. Accordingly, the at least one first coil 8231 includes a first sub-coil, a second sub-coil, a third sub-coil, and a fourth sub-coil. The extension direction of the first lower track 82511 is consistent with the extension direction of the first sub-coil, the extension direction of the second lower track 82521 is consistent with the extension direction of the second sub-coil, the extension direction of the third lower track 82531 is consistent with the extension direction of the third sub-coil, and the extension direction of the fourth lower track 82541 is consistent with the extension direction of the fourth sub-coil.

[0285] The upper and lower rails of each guide support unit of the guide support structure 825 extend perpendicularly to each other, forming a cross shape. The perpendicularity of the extension directions of the upper and lower rails prevents mutual interference when the outer carrier 8222 moves along the X-axis and Y-axis.

[0286] Accordingly, the extension direction of the first upper track 82512 is perpendicular to the extension direction of the first lower track 82511, the extension direction of the second lower track 82521 is perpendicular to the extension direction of the second upper track 82522, the extension direction of the third lower track 82531 is perpendicular to the extension direction of the third upper track 82532, and the extension direction of the fourth lower track 82541 is perpendicular to the extension direction of the fourth upper track 82542.

[0287] The guide support structure 825 has upper or lower tracks in each guide support unit that extend along both the X-axis and the Y-axis. Specifically, the lower track on the top surface of the base body 82111 of the base 8211 has both X-axis and Y-axis extensions; similarly, the upper track on the bottom surface of the outer carrier 8222 has both X-axis and Y-axis extensions. This arrangement prevents the ball bearings from rotating during optical image stabilization, thus avoiding interference with the driving effect. Furthermore, tracks with different extension directions are located on adjacent sides of the base 8211 to provide a larger mounting space for the first coil 8231.

[0288] The first lower track 82511, the second lower track 82521, the third lower track 82531, and the fourth lower track 82541 are rotationally symmetrical with respect to the optical axis. The first upper track 82512, the second upper track 82522, the third upper track 82532, and the fourth upper track 82542 are rotationally symmetrical with respect to the optical axis.

[0289] In this embodiment, the driving device 820 further includes an electrical connection member 826, such as... Figure 18 As shown. The electrical connection member 826 is disposed on the base 8211 of the fixing part 821 and electrically connected to the elastic member 824, so as to provide working power to the second coil 8232 and the first coil 8231 through the electrical connection member 826 and the elastic member 824. Figure 27 and Figure 28 As shown, the electrical connection member 826 includes an upper end 8261, a middle part 8262, and a lower end 8263. The upper end 8261, the middle part 8262, and the lower end 8263 are interconnected to achieve an electrical connection with an external power supply device through the electrical connection member 826, thereby providing power to the drive device 820.

[0290] Specifically, in this embodiment, the middle portion 8262 of the electrical connection member 826 is disposed within the base body 82111, and the upper end portion 8261 of the electrical connection member 826 extends integrally upward from the base support 82112 (e.g., Figure 27 and Figure 28 As shown), the lower end 8263 of the electrical connection member 826 extends downward from the base body 82111 (as shown). Figure 29As shown), it enables electrical communication with electronic devices external to the drive device 820. The middle portion 8262 of the electrical connection member 826 includes a plurality of electrical connection elements, at least one of the plurality of electrical connection elements of the middle portion 8262 of the electrical connection member 826 integrally extends upward to the top of the base support 82112 to form the upper end portion 8261 of the electrical connection member 826; at least one of the plurality of electrical connection elements of the middle portion 8262 of the electrical connection member 826 integrally extends downward from the base body 82111 to form the lower end portion 8263 of the electrical connection member 826.

[0291] Accordingly, in this embodiment, the focusing elastic portion 82411 of the first elastic component 8241 further includes a conductive end, wherein the conductive end extends outward from the inner contour of the focusing elastic portion. In a specific example of this application, there are two conductive ends, the positions of which correspond to the columnar protrusions 82211 of the inner carrier 8221, and the conductive ends are electrically connected to the second coil 8232 wound around the columnar protrusions 82211 of the inner carrier 8221.

[0292] The number of upper ends 8261 of the electrical connection member 826 is at least two, and the upper ends 8261 of the at least two electrical connection members 826 are electrically connected to the image stabilization elastic outer contour, so that the electrical energy provided by the external power supply device can pass sequentially through the lower end 8263, the middle part 8262, the upper end 8261, the image stabilization elastic part 82412, and the focusing elastic part 82411 of the electrical connection member 826 to the second coil 8232, thereby driving the inner carrier 8221.

[0293] In one specific example of this application, the number of upper ends 8261 of the electrical connection members 826 is four, respectively disposed on the four base supports 82112. In one specific example of this application, only the upper ends 8261 of the four electrical connection members 826 that simultaneously connect the image stabilization elastic portion 82412 and the focusing elastic portion 82411 achieve circuit conduction. Of course, it is understood that all four upper ends 8261 of the electrical connection members 826 can achieve circuit conduction, and this application does not limit this.

[0294] In one specific example of this application, the first elastic component 8241 has a split structure, the second elastic component 8242 has an integral structure, and the two electrical connection points of the second coil 8232 are electrically connected to the first elastic component 8241 to achieve electrical conduction of the second coil 8232. In another specific example of this application, the first elastic component 8241 has a split structure, the second elastic component 8242 has a split structure, and the two electrical connection points of the second coil 8232 can achieve circuit conduction by being electrically connected to the first elastic component 8241, or by being electrically connected to the second elastic component 8242. In another specific example of this application, the first elastic component 8241 has an integral structure, the second elastic component 8242 has an integral structure, and the two electrical connection points of the second coil 8232 cannot be simultaneously electrically connected to the first elastic component 8241. Therefore, the two electrical connection points of the second coil 8232 need to be electrically connected to the first elastic component 8241 and the second elastic component 8242 respectively to realize the electrical conduction of the second coil 8232.

[0295] The formation method of the electrical connection member 826 is not limited to this application. In one specific example of this application, the electrical connection member 826 is integrally formed into the base 8211 by an insert injection molding process. That is, the middle part 8262 of the electrical connection member 826 is integrally formed into the base body 82111, the upper end 8261 of the electrical connection member 826 is integrally formed into the base support 82112, and the lower end 8263 of the electrical connection member 826 extends downward from the base body 82111 and is exposed outside the base body 82111. In another specific example of this application, the electrical connection member 826 is formed onto the surface of the base 8211 by an attachment method.

[0296] In this embodiment of the application, the driving device 820 further includes a magnetically conductive member 827, such as... Figure 28 As shown. The magnetically conductive component 827 and the magnet 8233 are arranged opposite each other along a predetermined direction (e.g., the height direction). The formation method of the magnetically conductive component 827 is not limited to this application. In one specific example of this application, the magnetically conductive component 827 is integrally formed into the base body 82111 of the base 8211 by an insert injection molding process; in another specific example of this application, the magnetically conductive component 827 is fixed to the base body 82111 of the base 8211 by adhesive, so that the magnetically conductive component 827 can be opposite to the magnet 8233.

[0297] The magnetically conductive component 827 and the electrical connection component 826 should avoid mutual interference, which can be achieved in various ways. For example, the magnetically conductive component 827 can be located at the upper or lower end of the middle portion 8262 of the electrical connection component 826 to avoid interference between them. The magnetically conductive component 827 and the electrical connection component 826 can be made of different materials to avoid mutual interference. For example, the magnetically conductive component 827 can be made of a magnetically conductive material to generate a magnetic attraction between it and the magnet 8233, while the electrical connection component 826 can be made of a non-magnetically conductive material that enables signal conduction. This achieves independence between the magnetically conductive function and the electrical connection function of the drive device 820 and simplifies assembly.

[0298] The magnetically conductive component 827 is disposed at the corner of the base 8211, so that one magnetically conductive component 827 can simultaneously correspond to two adjacent magnets 8233. Through the magnetic attraction between the magnetically conductive component 827 and the magnets 8233, the guide support structure 825 can always be clamped between the base 8211 and the outer carrier 8222 (or the inner carrier 8221). During the optical image stabilization process, the guide support structure 825 can always maintain frictional contact with the base 8211 and the outer carrier 8222 (or the inner carrier 8221). Furthermore, the magnetically conductive component 827 and the magnet 8233 generate a magnetic attraction force along the Z-axis to maintain the stability of the movement of the outer carrier 8222 (or the inner carrier 8221), maintain the centering effect of the outer carrier 8222 (or the inner carrier 8221), and effectively prevent the outer carrier 8222 (or the inner carrier 8221) from falling off due to the shaking or inversion of the camera module.

[0299] In this embodiment, the driving device 820 further includes a position sensing element 828, such as... Figure 26As shown. The position sensing element 828 is disposed opposite to the magnet 8233 on the base 8211. When the outer carrier 8222 moves, the relative position of the position sensing element 828 and the magnet 8233 changes. Based on the strength of the magnetic field of the magnet 8233 sensed by the position sensing element 828, the position of the outer carrier 8222 can be determined, and the current of the first coil 8231 can be adjusted to move the outer carrier 8222 to the desired position. In this embodiment, the position sensing element 828 can be a Hall element, a driver integrated circuit (driver IC), or a tunnel magnetoresistive (TMR) element.

[0300] The specific location of the position sensing element 828 is not limited to this application. In one specific example, the top surface of the position sensing element 828 is not higher than the top surface of the first coil 8231. This reduces the height of the driving device 820 and protects the position sensing element 828 from collisions during movement. In another specific example, the position sensing element 828 is disposed on the bottom surface of the base 8211, such as... Figure 29 As shown.

[0301] The position sensing element 828 is electrically connected to the electrical connection member 826. The specific implementation of the electrical connection between the position sensing element 828 and the electrical connection member 826 is not limited to this application. In a specific example of this application, the base body 82111 of the base 8211 has an opening at the location of the position sensing element 828 as a mounting position for the position sensing element 828, allowing the position sensing element 828 to be directly connected to the electrical connection member 826 through this opening. Furthermore, as the height of the mounting position of the position sensing element 828 decreases, the height of the mounting position of the first coil 8231 can also decrease accordingly. This arrangement not only simplifies the circuit conduction method of the driving device 820 but also further reduces the height of the driving device 820.

[0302] In summary, the camera module based on the embodiments of this application is explained, wherein the driving device 820 mainly increases the placement space of the driving part 823 by reasonably arranging the driving part 823 and the guide support structure 825, thereby increasing the driving force of the driving part 823 without adding components, simplifying the design scheme for increasing the driving force of the driving part 823, and avoiding structural complexity of the driving part 823.

A first elastic component 7241 is mounted on the top surface of the 21, the top surface of the outer carrier 7222, and the top surface of the base 7211.

The focusing elastic portion 72411 and the image stabilizing elastic portion 72412 extend in a height plane perpendicular to the optical axis. The focusing elastic portion 72411 is arranged in a rotationally symmetrical manner with respect to the optical axis, and the image stabilizing elastic portion 72412 is arranged in an axially symmetrical manner with respect to the optical axis.
