[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2021-0141305, filed on October 21, 2021, with the Korean Intellectual Property Office, and Korean Patent Application No. 10-2022-0122721, filed on September 27, 2022, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

[0003] This disclosure relates to camera modules. Background Technology

[0004] In recent years, camera modules have been used in mobile communication terminals such as tablet PCs or laptops and smartphones.

[0005] The camera module includes actuators with autofocus (AF) and optical image stabilization (OIS) to generate high-resolution images.

[0006] For example, autofocus can be performed by moving the lens module in the direction of the optical axis, and optical image stabilization can be performed by moving the lens module in a direction perpendicular to the optical axis.

[0007] However, due to the improved performance of the camera module, the lens module may also have increased weight. Furthermore, the weight of the drive components used to move the lens module makes it difficult to precisely control the drive force used to perform optical image stabilization.

For purposes of clarity, illustration, and convenience, the drawings may not be drawn to scale, and the relative dimensions, scale, and depiction of elements in the drawings may be exaggerated. Detailed Implementation

[0075] The following detailed embodiments are provided to help the reader gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents to the methods, apparatus, and / or systems described herein will become apparent upon understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein, except for operations that must occur in a specific order, as will become apparent upon understanding the disclosure of this application. Furthermore, for clarity and conciseness, descriptions of features well-known in the art may be omitted.

[0076] The features described herein may be implemented in various forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein are provided merely to illustrate some of the many possible ways in which the methods, apparatuses, and / or systems described herein will become apparent upon understanding the disclosure of this application.

[0077] Throughout this specification, when an element such as a layer, region, or substrate is described as being "on," "connected to," or "attached to" another element, the element may be directly "on," directly "connected to," or directly "attached to" the other element, or there may be one or more other elements between the element and the other element. Conversely, when an element is described as being "directly on," "directly connected to," or "directly attached to" another element, there are no other elements between the element and the other element.

[0078] As used herein, the term “and / or” includes any one of the associated listed items and any combination of any two or more items.

[0079] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited by these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, first part, first region, first layer, or first section mentioned in these examples may also be referred to as a second component, second part, second region, second layer, or second section.

[0080] Spatial relative terms such as “above,” “above,” “below,” and “below” may be used herein for descriptive convenience to describe the relationship of one element relative to another, as shown in the accompanying drawings. In addition to covering the orientation depicted in the drawings, these spatial relative terms are intended to also cover different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “above” another element would be located “below” or “below” that other element. Thus, depending on the spatial orientation of the device, the term “above” covers both orientations of “above” and “below”. The device may also be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0081] The terminology used herein is for the purpose of describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the articles “a,” “an,” and “the” are intended to include the plural form as well. The terms “comprising,” “including,” and “having” indicate the presence of the stated features, numbers, operations, components, elements, and / or combinations thereof, but do not preclude the presence or addition of one or more other features, numbers, operations, components, elements, and / or combinations thereof.

[0082] Figure 1 This is a perspective view of a camera module according to an embodiment of the present disclosure. Figure 2 yes Figure 1 A schematic exploded stereoscopic view of the camera module.

[0083] The camera module 1 according to embodiments of this disclosure can be mounted on a portable electronic device. The portable electronic device can be a portable electronic device such as a mobile communication terminal, a smartphone, or a tablet personal computer (PC).

[0084] Reference Figure 1 and Figure 2 According to embodiments of the present disclosure, the camera module 1 may include a lens module 100, an autofocus (AF) housing 200, an optical image stabilization (OIS) housing 300, a moving frame 400, and a sensor substrate 800.

[0085] The lens module 100 may include a lens barrel 110 and a carrier portion 130. At least one lens may be disposed in the lens barrel 110. When multiple lenses are disposed in the lens barrel 110, the multiple lenses may be mounted in the lens barrel 110 along the optical axis (Z-axis).

[0086] The lens barrel 110 can be connected to the carrier portion 130. The carrier portion 130 may include a hollow portion passing through the carrier portion 130 in the optical axis (Z-axis) direction, and the lens barrel 110 can be inserted into the hollow portion and fixed to the carrier portion 130. Therefore, when the carrier portion 130 moves, the lens barrel 110 can move together with the carrier portion 130.

[0087] The lens module 100 can be housed in the AF housing 200. In one embodiment, the lens module 100 can be a movable member that moves in the direction of the optical axis (Z-axis) during autofocus (AF).

[0088] According to embodiments of the present disclosure, the camera module 1 may include a first drive portion 500 to move the lens module 100.

[0089] The lens module 100 can perform autofocus by moving relative to the AF housing 200 in the optical axis (Z axis) direction by the first drive part 500.

[0090] The AF housing 200 can be positioned on one side of the OIS housing 300 in the optical axis (Z-axis) direction, and the movable frame 400 can be positioned on the other side of the OIS housing 300 in the optical axis (Z-axis) direction. Furthermore, the movable frame 400 can be connected to a portion of the sensor substrate 800 on which the image sensor S is mounted.

[0091] In embodiments of this disclosure, one or both of the AF housing 200 and the moving frame 400 may be moving members that move in a plane perpendicular to the optical axis (Z-axis) during optical image stabilization (OIS).

[0092] According to embodiments of the present disclosure, the camera module 1 may include a second drive portion 600 for moving the AF housing 200 (see [link]). Figure 9 ) and the third drive section 700 for the mobile frame 400 (see Figure 12 ).

[0093] Optical image stabilization can be performed by the movement of the AF housing 200 relative to the OIS housing 300 in a plane perpendicular to the optical axis (Z-axis) by the second drive portion 600. The lens module 100 can be housed in the AF housing 200, and the lens module 100 can therefore also move with the AF housing 200 when the AF housing 200 moves.

[0094] Furthermore, the movable frame 400 can perform optical image stabilization by moving relative to the OIS housing 300 in a plane perpendicular to the optical axis (Z-axis) via the third drive portion 700. The movable frame 400 can move together with the image sensor S.

[0095] In other words, the image sensor S can be moved by the third drive section 700 in a direction perpendicular to the orientation of the imaging surface of the image sensor S. For example, the image sensor S can perform optical image stabilization by moving in a direction perpendicular to the optical axis (Z-axis) or rotating about the optical axis (Z-axis).

[0096] The housing 930 can be attached to the OIS housing 300 to protect the components in the camera module 1.

[0097] The housing 930 may include a protrusion 931 projecting toward the first ball unit B1 described below. The protrusion 931 may serve as a stop and buffer to limit the range of motion of the first ball unit B1.

[0098] In the camera module 1 according to an embodiment of the present disclosure, the lens module 100 can be a moving member during autofocus (AF), and the AF housing 200 can be a fixed member during autofocus (AF) and a moving member during optical image stabilization (OIS). Furthermore, the moving frame 400 (or image sensor S) can be a fixed member during autofocus (AF) and a moving member during optical image stabilization (OIS).

[0099] In this specification, the orientation of the imaging surface of the image sensor S can be referred to as the optical axis (Z-axis) direction. That is, the image sensor S can move in a direction perpendicular to the optical axis (Z-axis).

[0100] In this specification, when the image sensor S moves in a direction parallel to the imaging surface, it can be understood that the image sensor S moves in a direction perpendicular to the optical axis (Z-axis).

[0101] Furthermore, when the image sensor S moves in the first axis direction (or X-axis direction) or the second axis direction (or Y-axis direction), it can be understood that the image sensor S moves in a direction perpendicular to the optical axis (Z-axis).

[0102] Furthermore, for convenience, the rotation of the image sensor S about the optical axis (Z-axis) has already been described above. However, when the image sensor S rotates, the axis of rotation does not need to be aligned with the optical axis (Z-axis). For example, the image sensor S can rotate about any axis perpendicular to the direction in which the imaging surface of the image sensor S is oriented, that is, any axis parallel to the optical axis (Z-axis).

[0103] Furthermore, the first axial direction (or X-axis direction) and the second axial direction (or Y-axis direction) can be examples of two directions perpendicular to the optical axis (Z-axis) and intersecting each other. In this specification, the first axial direction (X-axis direction) and the second axial direction (Y-axis direction) can be understood as two directions perpendicular to the optical axis (Z-axis) and intersecting each other.

Figure 4 This is a side view of the load-bearing part and the AF housing. Figure 5 This is the front view of the supporting part. Figure 6 This is a 3D view of the AF housing. Figure 7 This is a view showing the first spherical unit disposed in the AF housing.

[0105] The following description is for reference. Figures 3 to 7 It describes the movement of the lens module in the direction of the optical axis (Z-axis).

[0106] First, refer to Figure 3 The lens module 100 may include a lens barrel 110 and a support portion 130 connected to the lens barrel 110. Alternatively, the lens barrel 110 and the support portion 130 may be integrally formed with each other.

[0107] The support portion 130 may include a hollow portion passing through the support portion 130 in the optical axis (Z-axis) direction, and the lens barrel 110 may be inserted into the hollow portion to be fixed to the support portion 130. Therefore, the lens barrel 110 and the support portion 130 can move together in the optical axis (Z-axis) direction.

[0108] The AF housing 200 may have an internal space and may have the shape of a quadrilateral box including an open top and an open bottom. The support portion 130 may be disposed in the internal space of the AF housing 200.

[0109] The first drive section 500 can generate a driving force in the optical axis (Z-axis) direction to move the bearing section 130 in the optical axis (Z-axis) direction.

[0110] The first drive section 500 may include a first magnet 510 and a first coil 530. The first magnet 510 and the first coil 530 may be arranged to face each other in a direction perpendicular to the optical axis (Z-axis).

[0111] The first magnet 510 may be provided on the support portion 130. For example, the first magnet 510 may be provided on one side of the support portion 130.

[0112] One side of the support portion 130 may protrude further in the optical axis (Z-axis) direction than other portions of the support portion 130. For example, the support portion 130 may include a first guide portion 131 that protrudes further in the optical axis (Z-axis) direction than other portions of the support portion 130, and the first magnet 510 may be disposed on the first guide portion 131. Therefore, by reducing the height of other portions of the support portion 130 while ensuring mounting space for the first magnet 510 to ensure driving force, the camera module 1 can have a smaller height (or can be manufactured to be thinner).

[0113] A rear yoke (not shown) may be disposed between the support portion 130 and the first magnet 510. The rear yoke can improve the driving force by preventing magnetic flux leakage from the first magnet 510.

[0114] The first magnet 510 can be magnetized such that one of its surfaces (e.g., the surface facing the first coil 530) has both an N pole and a S pole. For example, the N pole, the neutral region, and the S pole can be sequentially located on one surface of the first magnet 510 facing the first coil 530 in the optical axis (Z-axis) direction.

[0115] Another surface of the first magnet 510 (e.g., another surface opposite to one surface) can be magnetized to have both an S pole and a N pole. For example, the S pole, the neutral region, and the N pole can be sequentially located on the other surface of the first magnet 510 in the optical axis (Z-axis) direction, such that the S pole on the other surface is opposite to the N pole on one surface, and the N pole on the other surface is opposite to the S pole on one surface.

[0116] The first coil 530 can be configured to face the first magnet 510. For example, the first coil 530 can be configured to face the first magnet 510 in a direction perpendicular to the optical axis (Z-axis).

[0117] The first coil 530 can be disposed on the autofocus (AF) substrate 810, and the AF substrate 810 can be mounted in the AF housing 200 such that the first magnet 510 and the first coil 530 face each other in a direction perpendicular to the optical axis (Z-axis). The AF substrate 810 can be a component of the sensor substrate 800 described below.

[0118] One side of the AF housing 200 may protrude further in the optical axis (Z-axis) direction than other parts of the AF housing 200. For example, the AF housing 200 may include a second guide portion 230 that protrudes further in the optical axis (Z-axis) direction than other parts of the AF housing 200, and the AF substrate 810 may be mounted on the second guide portion 230.

[0119] In addition, such as Figure 4 and Figure 6 As shown, the second guide portion 230 may have a receiving space for accommodating the first guide portion 131.

[0120] Therefore, by reducing the height of other parts of the AF housing 200 while ensuring space for mounting the first drive section 500 to ensure driving force, the camera module 1 can be made to be very thin.

[0121] During autofocus, the first magnet 510 may be a moving member mounted on the support portion 130 and moving together with the support portion 130 in the optical axis (Z axis) direction, and the first coil 530 may be a fixed member mounted on the AF substrate 810.

[0122] When electricity is applied to the first coil 530, the carrier 130 can move in the optical axis (Z-axis) direction by the electromagnetic force generated between the first magnet 510 and the first coil 530.

[0123] The lens barrel 110 can be mounted on the support portion 130, and therefore the lens barrel 110 can also move in the optical axis (Z axis) direction by the movement of the support portion 130.

[0124] The first ball unit B1 can be disposed between the support portion 130 and the AF housing 200. For example, the first ball unit B1 can be disposed between the first guide portion 131 of the support portion 130 and the second guide portion 230 of the AF housing 200.

[0125] The first spherical unit B1 may include a first spherical group BG1 and a second spherical group BG2. The first spherical group BG1 and the second spherical group BG2 may be spaced apart from each other in a direction perpendicular to the optical axis (Z-axis).

[0126] The first ball group BG1 and the second ball group BG2 may each include multiple balls arranged in the optical axis (Z-axis) direction. When the support unit 130 moves in the optical axis (Z-axis) direction, the multiple balls can roll in the optical axis (Z-axis) direction.

[0127] The first magnetic yoke 550 may be disposed in the AF housing 200. The first magnetic yoke 550 may be disposed facing the first magnet 510. For example, the first coil 530 may be disposed on one surface of the AF substrate 810, and the first magnetic yoke 550 may be disposed on the other surface of the AF substrate 810.

[0128] The first magnet 510 and the first yoke 550 can generate an attractive force between each other. For example, the attractive force can act between the first magnet 510 and the first yoke 550 in a direction perpendicular to the optical axis (Z-axis).

[0129] Due to the attraction between the first magnet 510 and the first yoke 550, the first ball unit B1 can remain in contact with the support portion 130 and the AF housing 200.

[0130] Guide grooves can be formed in the opposing surfaces of the support portion 130 and the AF housing 200. For example, a first guide groove portion G1 can be formed on one of the opposing surfaces of the support portion 130 and the AF housing 200, and a second guide groove portion G2 can be formed on the other opposing surface of the support portion 130 and the AF housing 200. The first guide groove portion G1 and the second guide groove portion G2 can be spaced apart from each other in a direction perpendicular to the optical axis (Z-axis) (e.g., the first axis (X-axis) direction).

[0131] The first guide groove portion G1 and the second guide groove portion G2 can extend in a direction parallel to the optical axis (Z axis) and are formed in the first guide portion 131 of the support portion 130 and the second guide portion 230 of the AF housing 200.

[0132] The first guide groove portion G1 and the second guide groove portion G2 can extend in a direction parallel to the optical axis (Z-axis). The first ball group BG1 can be disposed in the first guide groove portion G1, and the second ball group BG2 can be disposed in the second guide groove portion G2.

[0133] The first guide groove portion G1 may include a first guide groove g1 formed in the first guide portion 131 of the support portion 130 and a second guide groove g2 formed in the second guide portion 230 of the AF housing 200; and the second guide groove portion G2 may include a third guide groove g3 formed in the first guide portion 131 of the support portion 130 and a fourth guide groove g4 formed in the second guide portion 230 of the AF housing 200. Each of the first guide groove g1 to the fourth guide groove g4 may extend in a direction parallel to the optical axis (Z-axis).

[0134] The first guide groove g1 and the second guide groove g2 can be arranged to face each other in a direction perpendicular to the optical axis (Z-axis) (e.g., the second axis (Y-axis) direction), and the first ball group BG1 can be arranged in the space between the first guide groove g1 and the second guide groove g2.

[0135] Among the multiple balls included in the first ball group BG1, the outermost ball in the direction parallel to the optical axis (Z axis) can contact the first guide groove g1 and the second guide groove g2 at two points respectively.

[0136] That is, among the multiple balls included in the first ball group BG1, the outermost ball in the direction parallel to the optical axis (Z axis) can make contact with the first guide groove g1 at two points and can make contact with the second guide groove g2 at two points.

[0137] The first ball group BG1, the first guide groove g1, and the second guide groove g2 can be used as main guides for guiding the movement of the lens module 100 in the optical axis (Z-axis) direction.

[0138] Furthermore, the third guide groove g3 and the fourth guide groove g4 can be arranged to face each other in a direction perpendicular to the optical axis (Z-axis) (e.g., the second axis (Y-axis) direction), and the second ball group BG2 can be arranged in the space between the third guide groove g3 and the fourth guide groove g4.

[0139] Among the multiple balls included in the second ball group BG2, the outermost ball in the direction parallel to the optical axis (Z-axis) can make contact with two points of one of the third guide groove g3 and the fourth guide groove g4, and can make contact with the other point of the third guide groove g3 and the fourth guide groove g4.

[0140] For example, among the multiple balls included in the second ball group BG2, the outermost ball in the direction parallel to the optical axis (Z-axis) can make point contact with the third guide groove g3 and two-point contact with the fourth guide groove g4. Alternatively, the outermost ball in the direction parallel to the optical axis (Z-axis) can make two-point contact with the third guide groove g3 and one-point contact with the fourth guide groove g4. The second ball group BG2, the third guide groove g3, and the fourth guide groove g4 can be used as auxiliary guides for guiding the movement of the lens module 100 in the direction of the optical axis (Z-axis).

[0141] The first ball group BG1 and the second ball group BG2 can be spaced apart from each other in a direction perpendicular to the optical axis (Z-axis) (e.g., the X-axis direction). The number of balls included in the first ball group BG1 and the number of balls included in the second ball group BG2 can be different from each other.

[0142] For example, the first ball group BG1 may include three or more balls arranged in a direction parallel to the optical axis (Z-axis), and the number of balls included in the second ball group BG2 may be less than the number of balls included in the first ball group BG1.

[0143] The number of balls included in the first group of balls BG1 and the second group of balls BG2 can be varied, provided that the number of balls included in the first group of balls BG1 is different from the number of balls included in the second group of balls BG2. In the following description, for ease of description, this specification describes an embodiment in which the first group of balls BG1 includes three balls and the second group of balls BG2 includes two balls.

[0144] Among the three balls included in the first ball group BG1, the two outermost balls positioned in a direction parallel to the optical axis (Z-axis) may have the same diameter, and the ball positioned between the two outermost balls may have a smaller diameter than the two outermost balls.

[0145] For example, among the multiple spheres included in the first sphere group BG1, the two outermost spheres positioned in a direction parallel to the optical axis (Z-axis) may have a first diameter, and a sphere positioned between the two outermost spheres may have a second diameter. The first diameter may be larger than the second diameter.

[0146] The two balls included in the second ball group BG2 can have the same diameter. For example, the two balls included in the second ball group BG2 can have a third diameter.

[0147] Furthermore, the first diameter and the third diameter can be identical to each other. In this document, identical diameter can refer to both the same diameter due to manufacturing errors and physically identical diameters.

[0148] The distance between the centers of the outermost balls in the first ball group BG1, which are arranged in a direction parallel to the optical axis (Z-axis), may be different from the distance between the centers of the outermost balls in the second ball group BG2, which are arranged in a direction parallel to the optical axis (Z-axis).

[0149] For example, the distance between the centers of two balls with a first diameter included in the first ball group BG1 can be greater than the distance between the centers of two balls with a third diameter included in the second ball group BG2.

[0150] The center point CP of the attraction force acting between the first magnet 510 and the first yoke 550 should be located within the support area A defined by connecting the contact points of the first ball group BG1 and the second ball group BG2 with the support portion 130 (or AF housing 200), so that when the support portion 130 moves in the optical axis (Z-axis) direction, it moves parallel to the optical axis (Z-axis) direction (i.e., to prevent the support portion 130 from tilting).

[0151] If the center point of the attractive force CP is outside the support area A, the support part 130 may shift during its movement, which could lead to the risk of the support part 130 tilting. Therefore, it is necessary to make the support area A as wide as possible.

[0152] In embodiments of this disclosure, each dimension (e.g., diameter) of some of the plurality of balls included in the first ball unit B1 may be intentionally larger than each dimension (e.g., diameter) of the other balls. In this case, the larger ball among the plurality of balls may intentionally come into contact with the support portion 130 (or the AF housing 200).

[0153] Reference Figure 7 In the first ball group BG1, two of the three balls may have a larger diameter than the third ball, and each of the two balls in the first ball group BG1 may contact the support portion 130 or the AF housing 200. Furthermore, the two balls in the second ball group BG2 may have the same diameter, and each of the two balls in the second ball group BG2 may contact the support portion 130 or the AF housing 200.

[0154] Therefore, as Figure 7 As shown, when viewed in the direction of the second axis (Y-axis), the first ball group BG1 and the second ball group BG2 can make contact with the AF housing 200 (or the support portion 130) at four points. Furthermore, the support area A defined by connecting the contact points together can have a trapezoidal shape.

[0155] Therefore, the support region A can be made wider, and the center point CP of the attraction force acting between the first magnet 510 and the first yoke 550 can thus be stably located within the support region A. This ensures the driving stability of the camera module during autofocus.

[0156] However, even if the two balls in the second ball group BG2 are manufactured to have the same diameter, due to manufacturing errors, the two balls in the second ball group BG2 may not have exactly the same diameter physically. In this case, only one of the two balls in the second ball group BG2 can contact the AF housing 200 (or the support portion 130).

[0157] Therefore, the support area A defined by connecting the first ball group BG1 and the second ball group BG2 to the contact point of the bearing portion 130 (or AF housing 200) may have a triangular shape.

[0158] Even when the support area A has a triangular shape, the support area A can be made wider by using the outermost ball among the three balls of the first ball group BG1 in the direction parallel to the optical axis (Z axis), thereby ensuring the driving stability of the camera module during autofocus.

[0159] In addition to ensuring drive stability during autofocus, it may also be important for the camera module 1 to have a small height (or be manufactured to be thin) in the optical axis (Z-axis) direction. When the camera module 1 simply has a small height in the optical axis (Z-axis) direction, the support region A may also have a small height in the optical axis (Z-axis) direction.

[0160] In other words, when the camera module 1 simply has a small height in the optical axis (Z-axis) direction, there is a risk that the driving stability of the camera module 1 may be problematic during autofocus.

[0161] Therefore, in the camera module 1 according to the embodiments of the present disclosure, the lengths of the first guide groove portion G1 and the second guide groove portion G2 in the optical axis (Z-axis) direction may be different from each other. For example, the length of the first guide groove portion G1 in the optical axis (Z-axis) direction may be longer than the length of the second guide groove portion G2 in the optical axis (Z-axis) direction.

[0162] Reference Figure 7 The protruding portions protruding toward the first ball group BG1 and the second ball group BG2 can be disposed on the second guide portion 230 of the AF housing 200. The protruding portions may include a first protruding portion 231 protruding toward the first ball group BG1 in the optical axis (Z-axis) direction and a second protruding portion 233 protruding toward the second ball group BG2 in the optical axis (Z-axis) direction.

[0163] The first protrusion 231 and the second protrusion 233 may protrude from the bottom surface of the second guide portion 230 of the AF housing 200 in the optical axis (Z-axis) direction. The lengths of the first protrusion 231 and the second protrusion 233 in the optical axis (Z-axis) direction may be different from each other. For example, the length of the second protrusion 233 in the optical axis (Z-axis) direction may be longer than the length of the first protrusion 231 in the optical axis (Z-axis) direction.

[0164] Therefore, the second guide groove g2 and the fourth guide groove g4 formed in the second guide portion 230 of the AF housing 200 by the first protrusion 231 and the second protrusion 233 can have different lengths in the optical axis (Z-axis) direction. For example, the length of the second guide groove g2 disposed therein in the first ball group BG1 in the optical axis (Z-axis) direction can be longer than the length of the fourth guide groove g4 disposed therein in the optical axis (Z-axis) direction.

[0165] In the main guide and the auxiliary guide, the length of the first guide groove portion G1 corresponding to the main guide can be longer than the length of the second guide groove portion G2 corresponding to the auxiliary guide, and therefore the camera module 1 can have a smaller size, while the support area A has a larger height in the optical axis (Z axis) direction.

[0166] With this configuration, the camera module 1 can achieve its slim profile by having a small height in the optical axis (Z-axis) direction while ensuring drive stability during autofocus.

[0167] Reference Figure 2 In this embodiment, a secondary magnetic yoke 590 may be provided to face the first magnet 510. The secondary magnetic yoke 590 may be fixed to the AF housing 200. For example, the secondary magnetic yoke 590 may be provided on the AF substrate 810 to face the first magnet 510.

[0168] The first coil 530 and the secondary yoke 590 can be disposed on one surface of the AF substrate 810, and the first yoke 550 can be disposed on the other surface of the AF substrate 810.

[0169] In another example, a guide hole can be formed through the AF substrate 810, and a secondary yoke 590 can be disposed in the guide hole to face the first magnet 510. In this case, the secondary yoke 590 can be mounted on the first yoke 550 to face the first magnet 510 through the guide hole.

[0170] The secondary yoke 590 can be positioned closer to the primary guide than to the secondary guide. For example, the secondary yoke 590 can be positioned closer to the first ball group BG1 (i.e., closer to the ball group containing more balls) than to the second ball group BG2.

[0171] The secondary yoke 590 can be made of a material that can generate an attractive force with the first magnet 510.

[0172] Therefore, the resultant force of the attraction between the first magnet 510 and the first yoke 550 and the attraction between the first magnet 510 and the secondary yoke 590 can be positioned closer to the main guide than the auxiliary guide.

[0173] The support area A can be closer to the main guide in the optical axis (Z-axis) direction and have a greater height, and therefore the center point of the attraction force CP can be more stably positioned within the support area A.

[0174] A buffer member can be disposed on one or both surfaces of the support portion 130 and the AF housing 200 that face each other in a direction parallel to the optical axis (Z-axis). The support portion 130 can move relative to the AF housing 200, and therefore, there is a risk that the surfaces of the support portion 130 and the AF housing 200 facing each other in a direction parallel to the optical axis (Z-axis) may collide with each other during the movement of the support portion 130. However, by disposing of a resilient buffer member on one or both surfaces of the support portion 130 and the AF housing 200 that face each other in a direction parallel to the optical axis (Z-axis), the impact and noise from such collisions can be mitigated.

[0175] Furthermore, a buffer member may be provided on one or two surfaces of the support portion 130 and the housing 930 that face each other in a direction parallel to the optical axis (Z-axis). The support portion 130 can move relative to the housing 930, and therefore, there is a risk that the surfaces of the support portion 130 and the housing 930 facing each other in a direction parallel to the optical axis (Z-axis) may collide with each other during the movement of the support portion 130. However, by providing a resilient buffer member on one or two surfaces of the support portion 130 and the housing 930 that face each other in a direction parallel to the optical axis (Z-axis), the impact and noise from such collisions can be mitigated.

[0176] According to the embodiments of the present disclosure, the camera module 1 can detect the position of the support portion 130 in the optical axis (Z-axis) direction.

[0177] For this purpose, a first position sensor 570 can be provided. The first position sensor 570 can be disposed on the AF substrate 810 so as to face the first magnet 510. The first position sensor 570 can be a Hall sensor.

[0178] Figure 8 This is an exploded perspective view of the AF housing and the optical image stabilization (OIS) housing in a camera module according to an embodiment of the present disclosure. Figure 9 This is an exploded 3D view of the second drive section. Figure 10 These are three-dimensional views of the OIS housing, as well as enlarged views of the fifth guide groove and the second ball unit.

[0179] First, refer to Figure 8 The support portion 130 can be accommodated in the AF housing 200, and the AF housing 200 can be disposed in the OIS housing 300.

[0180] The OIS housing 300 may include a main body portion 310 therein housing the lens module 100 (see...). Figure 2 ).

[0181] The first guide portion 131 of the support portion 130 and the second guide portion 230 of the AF housing 200 can each protrude further in the optical axis (Z axis) direction than the other portions of the support portion 130 and the second guide portion 230, and thus a receiving space can be provided in the OIS housing 300 to fix the mounting of the first guide portion 131 and the second guide portion 230.

[0182] In other words, such as Figure 8 As shown, the stepped portion 330 can be provided on one side of the OIS housing 300 to provide a receiving space for the second guide portion 230.

[0183] The mounting space for the first guide portion 131 and the second guide portion 230 can be fixed by the step portion 330.

[0184] Therefore, even when the first guide portion 131 of the support portion 130 and the second guide portion 230 of the AF housing 200 protrude in the optical axis (Z-axis) direction, a protrusion can be provided in the OIS housing 300. As a result, the overall height of the camera module 1 does not need to be increased.

[0185] The AF housing 200 can be disposed within the OIS housing 300 and can move relative to the OIS housing 300 in a plane perpendicular to the optical axis (Z-axis).

[0186] The lens module 100 can be disposed within the AF housing 200, and when the AF housing 200 moves, the lens module 100 can also move in a plane perpendicular to the optical axis (Z-axis). Therefore, the lens module 100 can move in a plane perpendicular to the optical axis (Z-axis) to perform optical image stabilization during image capture.

[0187] The second drive section 600 can generate a driving force in a direction perpendicular to the optical axis (Z-axis) to move the AF housing 200 in a direction perpendicular to the optical axis (Z-axis), or to rotate the AF housing 200 about the optical axis (Z-axis) or any axis parallel to the optical axis (Z-axis) as the rotation axis of the AF housing 200.

[0188] The second drive section 600 may include a first sub-drive section 610 and a second sub-drive section 630. The first sub-drive section 610 may generate a driving force in the direction of a first axis (X-axis), and the second sub-drive section 630 may generate a driving force in the direction of a second axis (Y-axis).

[0189] The first sub-drive section 610 may include a second magnet 611 and a second coil 613. The second magnet 611 and the second coil 613 may be arranged to face each other in the optical axis (Z-axis) direction.

[0190] The second magnet 611 can be disposed in the OIS housing 300. The second magnet 611 may include multiple magnets. For example, the second magnet 611 may include two magnets, and the two magnets may be symmetrically spaced apart from each other with respect to the optical axis (Z-axis).

[0191] For example, the second magnet 611 may include two magnets spaced apart from each other in the direction in which the second magnet 611 generates driving force (e.g., the direction of the first axis (X-axis)).

[0192] A mounting groove 350 for accommodating the second magnet 611 can be formed in the upper surface of the OIS housing 300 (see [link]). Figure 2 The second magnet 611 can be inserted into the mounting slot 350, thereby preventing an increase in the overall height of the camera module 1 due to the thickness of the second magnet 611.

[0193] The second magnet 611 can be magnetized such that one of its surfaces (e.g., the surface facing the second coil 613) has both a N pole and a S pole. For example, the N pole, neutral region, and S pole can be sequentially located on one surface of the second magnet 611 facing the second coil 613 in the direction of the first axis (X-axis). The second magnet 611 can be elongated in the direction of the second axis (Y-axis).

[0194] Another surface of the second magnet 611 (e.g., another surface opposite to one surface) can be magnetized to have both an S pole and a N pole. For example, the S pole, the neutral region, and the N pole can be sequentially located on the other surface of the second magnet 611 in the direction of the first axis (X-axis), such that the S pole on the other surface is opposite to the N pole on one surface, and the N pole on the other surface is opposite to the S pole on one surface.

[0195] The second coil 613 can be configured to face the second magnet 611. For example, the second coil 613 can be configured to face the second magnet 611 in the optical axis (Z-axis) direction.

[0196] The second coil 613 may have a hollow ring shape and may extend in the direction of the second axis (Y-axis). The second coil 613 may include a number of coils corresponding to the number of magnets included in the second magnet 611.

[0197] The second coil 613 can be disposed on the first optical image stabilization (OIS) substrate 830. The first OIS substrate 830 can be a component of the sensor substrate 800 described below. A portion of the first OIS substrate 830 can be mounted in the AF housing 200 such that the second magnet 611 and the second coil 613 face each other in the optical axis (Z-axis) direction, and other portions of the first OIS substrate 830 can be mounted in the OIS housing 300 or the outer casing 930.

[0198] The AF housing 200 may include a body portion 210 therein for accommodating the lens module 100 and a flange portion 250 extending from the body portion 210 in a direction perpendicular to the optical axis (Z-axis).

[0199] The AF housing 200 may include a through-hole 251. For example, the through-hole 251 may pass through the flange portion 250 of the AF housing 200 in the optical axis (Z-axis) direction. A second coil 613 may be disposed in the through-hole 251 of the AF housing 200 to prevent an increase in the overall height of the camera module 1 due to the thickness of the second coil 613.

[0200] The upper part of the through hole 251 in the AF housing 200 can be covered by the first OIS substrate 830.

[0201] During optical image stabilization, the second magnet 611 can be a fixed member fixed to the OIS housing 300, and the second coil 613 can be a movable member mounted on the first OIS substrate 830 and the AF housing 200 to move together with the AF housing 200.

[0202] When power is applied to the second coil 613, the AF housing 200 can move in the direction of the first axis (X-axis) by the electromagnetic force generated between the second magnet 611 and the second coil 613.

[0203] The second magnet 611 and the second coil 613 can generate a driving force in a direction perpendicular to the direction in which the second magnet 611 and the second coil 613 face each other (or the optical axis direction) (e.g., the first axis (X-axis) direction).

[0204] The second sub-drive section 630 may include a third magnet 631 and a third coil 633. The third magnet 631 and the third coil 633 may be arranged to face each other in the optical axis (Z-axis) direction.

[0205] The third magnet 631 may be disposed in the OIS housing 300. The third magnet 631 may include multiple magnets. For example, the third magnet 631 may include two magnets, and the two magnets may be spaced apart from each other in the direction of the first axis (X-axis).

[0206] For example, the third magnet 631 may include two magnets spaced apart from each other in a direction perpendicular to the direction in which the third magnet 631 generates a driving force (e.g., the direction of the first axis (X-axis)).

[0207] A mounting groove 350 for housing the third magnet 631 can be formed in the upper surface of the OIS housing 300. The third magnet 631 can be inserted into the mounting groove 350, thereby preventing an increase in the overall height of the camera module 1 due to the thickness of the third magnet 631.

[0208] The third magnet 631 can be magnetized such that one of its surfaces (e.g., the surface facing the third coil 633) has both an S pole and a N pole. For example, the S pole, neutral region, and N pole can be sequentially located on one surface of the third magnet 631 facing the third coil 633 in the direction of the second axis (Y-axis). The third magnet 631 can be elongated in the direction of the first axis (X-axis).

[0209] Another surface of the third magnet 631 (e.g., another surface opposite to one surface) can be magnetized to have both an N pole and a S pole. For example, the N pole, the neutral region, and the S pole can be sequentially located on the other surface of the third magnet 631 in the direction of the second axis (Y-axis), such that the N pole on the other surface is opposite to the S pole on one surface, and the S pole on the other surface is opposite to the N pole on one surface.

[0210] The third coil 633 can be configured to face the third magnet 631. For example, the third coil 633 can be configured to face the third magnet 631 in the optical axis (Z-axis) direction.

[0211] The third coil 633 may have a hollow ring shape and may extend in the direction of the first axis (X-axis). The third coil 633 may include a number of coils corresponding to the number of magnets included in the third magnet 631.

[0212] The third coil 633 can be disposed on the first OIS substrate 830. The first OIS substrate 830 can be a component of the sensor substrate 800 described below. A portion of the first OIS substrate 830 can be mounted in the AF housing 200 such that the third magnet 631 and the third coil 633 face each other in the optical axis (Z-axis) direction, and other portions of the first OIS substrate 830 can be mounted in the OIS housing 300 or the outer casing 930.

[0213] The AF housing 200 may include a through-hole 251. For example, the through-hole 251 may pass through the flange portion 250 of the AF housing 200 in the optical axis (Z-axis) direction. A third coil 633 may be disposed in the through-hole 251 of the AF housing 200 to prevent an increase in the overall height of the camera module 1 due to the thickness of the third coil 633.

[0214] The upper part of the through hole 251 in the AF housing 200 can be covered by the first OIS substrate 830.

[0215] During optical image stabilization, the third magnet 631 may be a fixed member fixed to the OIS housing 300, and the third coil 633 may be a movable member mounted on the first OIS substrate 830 and the AF housing 200 to move together with the AF housing 200.

[0216] When power is applied to the third coil 633, the AF housing 200 can move in the direction of the second optical axis (Y axis) by the electromagnetic force generated between the third magnet 631 and the third coil 633.

[0217] The third magnet 631 and the third coil 633 can generate a driving force in a direction perpendicular to the direction in which the third magnet 631 and the third coil 633 face each other (or the optical axis direction) (e.g., the direction of the second axis (Y axis)).

[0218] The AF housing 200 can be rotated about the optical axis (Z-axis) or any axis parallel to the optical axis (Z-axis) by the first sub-drive portion 610 and the second sub-drive portion 630.

[0219] The second magnet 611 and the third magnet 631 can be arranged perpendicularly to each other on a plane perpendicular to the optical axis (Z-axis), and the second coil 613 and the third coil 633 can also be arranged perpendicularly to each other on a plane perpendicular to the optical axis (Z-axis).

[0220] During optical image stabilization, the second coil 613 and the third coil 633 can move together with the AF housing 200, and the first OIS substrate 830 on which the second coil 613 and the third coil 633 are mounted can thus support the movement of the second coil 613 and the third coil 633. See below for reference. Figures 18 to 20 Describe this configuration.

[0221] The second spherical unit B2 can be located between the AF housing 200 and the OIS housing 300.

[0222] The second ball unit B2 can be configured to contact each of the AF housing 200 and the OIS housing 300.

[0223] The second ball unit B2 can be used to guide the movement of the AF housing 200 during optical image stabilization processing. The second ball unit B2 can also be used to maintain the gap between the AF housing 200 and the OIS housing 300.

[0224] When a driving force is generated in the first axis (X-axis) direction, the second ball unit B2 can roll in the first axis (X-axis) direction. Therefore, the second ball unit B2 can guide the movement of the AF housing 200 in the first axis (X-axis) direction.

[0225] Furthermore, when a driving force is generated in the second axis (Y-axis) direction, the second ball unit B2 can roll in the second axis (Y-axis) direction. Therefore, the second ball unit B2 can guide the movement of the AF housing 200 in the second axis (Y-axis) direction.

[0226] The second ball unit B2 may include multiple balls disposed between the AF housing 200 and the OIS housing 300.

[0227] Reference Figure 8 and Figure 10 The fifth guide groove g5 for the second ball unit B2 can be formed in one or both of the surfaces of the AF housing 200 and the OIS housing 300 that face each other in the optical axis (Z-axis) direction. The number of fifth guide grooves g5 can correspond to the number of balls included in the second ball unit B2.

[0228] For example, the fifth guide groove g5 can be formed in one or both of the lower surface of the AF housing 200 and the upper surface of the OIS housing 300.

[0229] The second ball unit B2 can be set in the fifth guide groove g5 and assembled between the AF housing 200 and the OIS housing 300.

[0230] The fifth guide groove g5 can be polygonal or circular. The size of the fifth guide groove g5 can be larger than the diameter of the plurality of spheres included in the second spherical unit B2. For example, the cross-section of the fifth guide groove g5 in a plane perpendicular to the optical axis (Z-axis) can have a size larger than the diameter of the plurality of spheres included in the second spherical unit B2.

[0231] The specific shape of the fifth guide groove g5 is not limited, as long as its size is greater than the diameter of the multiple spheres included in the second sphere unit B2.

[0232] Therefore, the multiple balls included in the second ball unit B2 can roll in a direction perpendicular to the optical axis (Z axis) while being housed in the fifth guide groove g5.

[0233] The support pad can be disposed in the AF housing 200 and the OIS housing 300, and at least a portion of the support pad disposed in the OIS housing 300 can form the bottom surface of the fifth guide groove g5. Therefore, the plurality of balls included in the second ball unit B2 can roll contact with the support pad.

[0234] The support pad can be integrally connected to the AF housing 200 and OIS housing 300 via injection molding. In this case, the support pad can be integrally formed with the AF housing 200 and OIS housing 300 by injecting resin material into the mold while the support pad is fixed in the mold.

[0235] The support pad can be made of stainless steel.

[0236] When a driving force is generated in the first axis (X-axis) direction, the AF housing 200 can move in the first axis (X-axis) direction, and when a driving force is generated in the second axis (Y-axis) direction, the AF housing 200 can move in the second axis (Y-axis) direction.

[0237] Furthermore, by creating deviations in one or both of the magnitudes of the driving force generated in the first axis (X-axis) direction and the driving force generated in the second axis (Y-axis) direction, the AF housing 200 can rotate about the optical axis (Z-axis) or any axis parallel to the optical axis (Z-axis).

[0238] According to the embodiments of the present disclosure, the camera module 1 can detect the position of the AF housing 200 in a direction perpendicular to the optical axis (Z-axis).

[0239] For this purpose, a second position sensor 615 and a third position sensor 635 can be provided. The second position sensor 615 can be disposed on the first OIS substrate 830 facing the second magnet 611, and the third position sensor 635 can be disposed on the first OIS substrate 830 facing the third magnet 631. The second position sensor 615 and the third position sensor 635 can be Hall sensors.

[0240] The third position sensor 635 may include two Hall sensors. For example, the third magnet 631 may include two magnets spaced apart from each other in a direction perpendicular to the direction in which the third magnet 631 generates a driving force (e.g., the direction of the second axis (Y-axis)) (e.g., the direction of the first axis (X-axis)), and the third position sensor 635 may include two Hall sensors facing the two magnets.

[0241] Whether the AF housing 200 rotates can be detected by two Hall sensors facing the two magnets of the third magnet 631.

[0242] Rotational force can be intentionally generated by using the deviation generated in the driving force of the first sub-drive portion 610 and the driving force of the second sub-drive portion 630, the resultant force of the first sub-drive portion 610 and the second sub-drive portion 630, the two magnets included in the second sub-drive portion 630, or any other suitable technique.

[0243] The fifth guide groove g5 may have a polygonal or circular shape, and its size is larger than the diameter of the plurality of balls included in the second ball unit B2. The plurality of balls included in the second ball unit B2 disposed in the fifth guide groove g5 may roll freely in a direction perpendicular to the optical axis (Z axis).

[0244] Therefore, the AF housing 200 can rotate about the optical axis (Z-axis) or any axis parallel to the optical axis (Z-axis) while being supported by the second ball unit B2.

[0245] Furthermore, when the camera module 1 requires linear motion without rotation, the unexpected rotational force can be counteracted by controlling the driving force of the first sub-drive section 610 and / or the driving force of the second sub-drive section 630.

[0246] A second and a third magnetic yoke (not shown) may be disposed in the AF housing 200. The second and third magnetic yokes can provide attractive forces such that the AF housing 200 and the OIS housing 300 remain in contact with the second spherical unit B2.

[0247] The second and third magnetic yokes can be fixed to the AF housing 200. For example, the second and third magnetic yokes can be disposed on the first OIS substrate 830, and the first OIS substrate 830 can be connected to the AF housing 200.

[0248] The second coil 613 and the third coil 633 can be disposed on one surface of the first OIS substrate 830, and the second magnetic yoke and the third magnetic yoke can be disposed on the other surface of the first OIS substrate 830.

[0249] The second magnetic yoke can be configured to face the second magnet 611 in the optical axis (Z-axis) direction, and the third magnetic yoke can be configured to face the third magnet 631 in the optical axis (Z-axis) direction.

[0250] The attractive force can act between the second yoke and the second magnet 611 and between the third yoke and the third magnet 631 in the direction of the optical axis (Z-axis).

[0251] Therefore, the AF housing 200 can be pressed against the OIS housing 300, and thus the AF housing 200 and the OIS housing 300 can remain in contact with the second ball unit B2.

[0252] The second and third magnetic yokes can each be made of materials that generate attractive forces between the second and third magnetic yokes and the second magnet 611 and the third magnet 631. For example, the second and third magnetic yokes can each be made of magnetic materials.

[0253] Figure 11 This is an exploded perspective view of the OIS housing and moving frame in a camera module according to an embodiment of the present disclosure. Figure 12 This is an exploded 3D view of the third drive section. Figure 13 It is an exploded 3D view of the moving frame. Figure 14 and Figure 15 It is a partially exploded 3D view of the moving frame. Figure 16 It is a 3D view of the moving frame. Figure 17 This is a bottom view of the moving frame.

[0254] First, refer to Figure 11 The movable frame 400 can be housed in the OIS housing 300. The OIS housing 300 can have sidewalls extending downward in the optical axis (Z-axis) direction, and thus have a receiving space for accommodating the movable frame 400.

[0255] The AF housing 200 can be positioned on one side of the OIS housing 300 in the optical axis (Z-axis) direction, and the movable frame 400 can be positioned on the other side of the OIS housing 300 in the optical axis (Z-axis) direction.

[0256] The movable frame 400 can move relative to the OIS housing 300 in a direction perpendicular to the optical axis (Z-axis), or rotate about the optical axis (Z-axis) or any axis parallel to the optical axis (Z-axis) as its rotation axis. That is, the movable frame 400 can be a movable component that moves during optical image stabilization.

[0257] For example, the movable frame 400 can move in the direction of the first axis (X-axis) or the second axis (Y-axis) and rotate about the optical axis (Z-axis) or any axis parallel to the optical axis (Z-axis) as its rotation axis.

[0258] The movable frame 400 can have a quadrilateral plate shape with a central opening in the optical axis (Z-axis) direction.

[0259] Infrared cut-off filter 450 (see) Figure 13 The sensor substrate 800 can be mounted on the upper surface of the movable frame 400. The sensor substrate 800 can be mounted on the lower surface of the movable frame 400.

[0260] The third ball unit B3 can be positioned between the OIS housing 300 and the movable frame 400.

[0261] The third ball unit B3 can be configured to contact each of the OIS housing 300 and the movable frame 400.

[0262] When the movable frame 400 moves or rotates relative to the OIS housing 300, the third ball unit B3 can roll between the OIS housing 300 and the movable frame 400 to support the movement of the movable frame 400.

[0263] Reference Figure 2The image sensor S can be mounted on the sensor substrate 800. A portion of the sensor substrate 800 can be connected to the movable frame 400, and another portion of the sensor substrate 800 can be connected to the OIS housing 300.

[0264] The image sensor S can be mounted on a portion of the sensor substrate 800 that is connected to the movable frame 400.

[0265] A portion of the sensor substrate 800 may be coupled to the movable frame 400, and thus a portion of the sensor substrate 800 may also move or rotate with the movable frame 400 when the movable frame 400 moves or rotates.

[0266] Therefore, the image sensor S can move or rotate in a plane perpendicular to the optical axis (Z-axis) to perform optical image stabilization during image capture.

[0267] The third drive section 700 can generate a driving force in a direction perpendicular to the optical axis (Z-axis) to move the moving frame 400 in a direction perpendicular to the optical axis (Z-axis), or to rotate the moving frame 400 about the optical axis (Z-axis) or any axis parallel to the optical axis (Z-axis) as the rotation axis of the moving frame 400.

[0268] The third drive section 700 may include a third sub-drive section 710 and a fourth sub-drive section 730. The third sub-drive section 710 may generate a driving force in the direction of the first axis (X-axis), and the fourth sub-drive section 730 may generate a driving force in the direction of the second axis (Y-axis).

[0269] The third sub-drive section 710 may include a fourth magnet 711 and a fourth coil 713. The fourth magnet 711 and the fourth coil 713 may be arranged to face each other in the optical axis (Z-axis) direction.

[0270] The fourth magnet 711 may be disposed in the OIS housing 300. The fourth magnet 711 may include multiple magnets. For example, the fourth magnet 711 may include two magnets, and the two magnets may be symmetrically spaced apart from each other with respect to the optical axis (Z-axis).

[0271] For example, the fourth magnet 711 may include two magnets spaced apart from each other in the direction in which the fourth magnet 711 generates driving force (i.e., the direction of the first axis (or X-axis)).

[0272] A mounting groove 370 for housing the fourth magnet 711 can be formed on the lower surface of the OIS housing 300. The fourth magnet 711 can be inserted into the mounting groove 370, thereby preventing an increase in the overall height of the camera module 1 due to the thickness of the fourth magnet 711.

[0273] The fourth magnet 711 can be magnetized such that one of its surfaces (e.g., the surface facing the fourth coil 713) has both a N pole and a S pole. For example, the N pole, neutral region, and S pole can be sequentially located on one surface of the fourth magnet 711 facing the fourth coil 713 in the first axis (X-axis) direction. The fourth magnet 711 can be elongated in the second axis (Y-axis) direction.

[0274] Another surface of the fourth magnet 711 (e.g., another surface opposite to one surface) can be magnetized to have both an S pole and a N pole. For example, the S pole, the neutral region, and the N pole can be sequentially located on the other surface of the fourth magnet 711 in the direction of the first axis (X-axis), such that the S pole on the other surface is opposite to the N pole on one surface, and the N pole on the other surface is opposite to the S pole on one surface.

[0275] The fourth coil 713 can be configured to face the fourth magnet 711. For example, the fourth coil 713 can be configured to face the fourth magnet 711 in the optical axis (Z-axis) direction.

[0276] The fourth coil 713 may have a hollow ring shape and may extend in the direction of the second axis (Y-axis). The fourth coil 713 may include a number of coils corresponding to the number of magnets included in the fourth magnet 711.

[0277] The fourth coil 713 can be installed in the movable frame 400.

[0278] During optical image stabilization, the fourth magnet 711 can be a fixed member fixed to the OIS housing 300, and the fourth coil 713 can be a movable member mounted in the movable frame 400 and moving together with the movable frame 400.

[0279] When electricity is applied to the fourth coil 713, the movable frame 400 can move in the direction of the first axis (X-axis) by the electromagnetic force generated between the fourth magnet 711 and the fourth coil 713.

[0280] The fourth magnet 711 and the fourth coil 713 can generate a driving force in a direction perpendicular to the direction in which the fourth magnet 711 and the fourth coil 713 face each other (or the optical axis direction) (e.g., the first axis (X-axis) direction).

[0281] The fourth sub-drive section 730 may include a fifth magnet 731 and a fifth coil 733. The fifth magnet 731 and the fifth coil 733 may be arranged to face each other in the optical axis (Z-axis) direction.

[0282] The fifth magnet 731 may be disposed in the OIS housing 300. The fifth magnet 731 may include multiple magnets. For example, the fifth magnet 731 may include two magnets, and the two magnets may be spaced apart from each other in the direction of the first axis (X-axis).

[0283] For example, the fifth magnet 731 may include two magnets spaced apart from each other in a direction perpendicular to the direction in which the fifth magnet 731 generates a driving force (e.g., the first axis (X-axis direction)).

[0284] A mounting groove 370 for housing the fifth magnet 731 can be formed in the lower surface of the OIS housing 300. The fifth magnet 731 can be inserted into the mounting groove 370, thereby preventing an increase in the overall height of the camera module 1 due to the thickness of the fifth magnet 731.

[0285] The fifth magnet 731 can be magnetized such that one of its surfaces (e.g., the surface facing the fifth coil 733) has both an S pole and a N pole. For example, the S pole, neutral region, and N pole can be sequentially located on one surface of the fifth magnet 731 facing the fifth coil 733 in the direction of the second axis (Y-axis). The fifth magnet 731 can be elongated in the direction of the first axis (X-axis).

[0286] Another surface of the fifth magnet 731 (e.g., another surface opposite to one surface) can be magnetized to have both an N pole and a S pole. For example, the N pole, the neutral region, and the S pole can be sequentially located on the other surface of the fifth magnet 731 in the direction of the second axis (Y-axis), such that the N pole on the other surface is opposite to the S pole on one surface, and the S pole on the other surface is opposite to the N pole on one surface.

[0287] The fifth coil 733 can be configured to face the fifth magnet 731. For example, the fifth coil 733 can be configured to face the fifth magnet 731 in the optical axis (Z-axis) direction.

[0288] The fifth coil 733 may have a hollow ring shape and may extend in the direction of the first axis (X-axis). The fifth coil 733 may include a number of coils corresponding to the number of magnets included in the fifth magnet 731.

[0289] The fifth coil 733 can be installed in the movable frame 400.

[0290] During optical image stabilization, the fifth magnet 731 can be a fixed member fixed to the OIS housing 300, and the fifth coil 733 can be a movable member mounted in the movable frame 400 and moving together with the movable frame 400.

[0291] When electricity is applied to the fifth coil 733, the moving frame 400 can move in the direction of the second optical axis (Y axis) by the electromagnetic force generated between the fifth magnet 731 and the fifth coil 733.

[0292] The fifth magnet 731 and the fifth coil 733 can generate a driving force in a direction perpendicular to the direction in which the fifth magnet 731 and the fifth coil 733 face each other (or the optical axis direction) (e.g., the direction of the second axis (Y axis)).

[0293] The movable frame 400 can be rotated by the third sub-drive section 710 and the fourth sub-drive section 730.

[0294] For example, rotational force can be generated by controlling the driving force of the third sub-drive section 710 and the driving force of the fourth sub-drive section 730, thereby causing the moving frame 400 to rotate.

[0295] The fourth magnet 711 and the fifth magnet 731 can be arranged perpendicularly to each other on a plane perpendicular to the optical axis (Z-axis), and the fourth coil 713 and the fifth coil 733 can also be arranged perpendicularly to each other on a plane perpendicular to the optical axis (Z-axis).

[0296] The third ball unit B3 can be positioned between the OIS housing 300 and the movable frame 400.

[0297] The third ball unit B3 can be configured to contact each of the OIS housing 300 and the movable frame 400.

[0298] The third ball unit B3 can be used to guide the movement of the moving frame 400 during optical image stabilization processing. Furthermore, the third ball unit B3 can be used to maintain the gap between the OIS housing 300 and the moving frame 400.

[0299] When a driving force is generated in the first axis (X-axis) direction, the third ball unit B3 can roll in the first axis (X-axis) direction. Therefore, the third ball unit B3 can guide the movement of the moving frame 400 in the first axis (X-axis) direction.

[0300] Furthermore, when a driving force is generated in the second axis (Y-axis) direction, the third ball unit B3 can roll in the second axis (Y-axis) direction. Therefore, the third ball unit B3 can guide the movement of the moving frame 400 in the second axis (Y-axis) direction.

[0301] The third ball unit B3 may include multiple balls disposed between the OIS housing 300 and the movable frame 400.

[0302] A sixth guide groove g6, in which the third ball unit B3 is disposed, can be formed in one or both of the surfaces of the OIS housing 300 and the movable frame 400 that face each other in the optical axis (Z-axis) direction. The number of sixth guide grooves g6 can correspond to the number of balls included in the third ball unit B3.

[0303] For example, the sixth guide groove g6 can be formed in one or both of the lower surface of the OIS housing 300 and the upper surface of the moving frame 400.

[0304] The third ball unit B3 can be set in the sixth guide groove g6 and assembled between the OIS housing 300 and the moving frame 400.

[0305] The sixth guide groove g6 can be polygonal or circular. The size of the sixth guide groove g6 can be larger than the diameter of the plurality of spheres included in the third spherical unit B3. For example, the cross-sectional dimension of the sixth guide groove g6 in a plane perpendicular to the optical axis (Z-axis) can be larger than the diameter of the plurality of spheres included in the third spherical unit B3.

[0306] The specific shape of the sixth guide groove g6 is not limited, as long as its size is greater than the diameter of the multiple spheres included in the third sphere unit B3.

[0307] Therefore, the multiple balls included in the third ball unit B3 can roll in a direction perpendicular to the optical axis (Z axis) while being housed in the sixth guide groove g6.

[0308] When a driving force is generated in the first axis (X-axis) direction, the moving frame 400 can move in the first axis (X-axis) direction.

[0309] Furthermore, when a driving force is generated in the second axis (Y-axis) direction, the moving frame 400 can move in the second axis (Y-axis) direction.

[0310] Furthermore, the movable frame 400 can rotate by creating a deviation in one or both of the magnitude of the driving force generated in the first axis (X-axis) direction and the magnitude of the driving force generated in the second axis (Y-axis) direction.

[0311] A portion of the sensor substrate 800 can be connected to the movable frame 400, and the image sensor S can be mounted on the sensor substrate 800. As a result, the image sensor S can also move or rotate when the movable frame 400 moves or rotates.

[0312] Simultaneously, a protrusion protruding toward the sensor substrate 800 can be provided on the movable frame 400. For example, the protrusion can be provided on the lower surface of the movable frame 400, and the protrusion can be connected to the second movable portion 851 of the sensor substrate 800 (see...). Figure 20Therefore, a gap can be formed between the main body of the moving frame 400 (excluding the protrusion) and the sensor substrate 800 in the optical axis (Z-axis) direction, thereby preventing interference between the moving frame 400 and the sensor substrate 800 when the moving frame 400 moves in the XY plane.

[0313] Although the protrusion has been described as being disposed on the lower surface of the movable frame 400, this configuration is merely an example, and the protrusion may also be disposed on the upper surface of the sensor substrate 800.

[0314] Figure 22 The positional relationship between the first spherical unit B1, the second spherical unit B2, and the third spherical unit B3 is shown.

[0315] Refer to together Figure 8 and Figure 22 The support portion 130 may include a first guide portion 131 protruding in the optical axis (Z-axis) direction, and the AF housing 200 may include a second guide portion 230 protruding in the optical axis (Z-axis) direction. The first guide portion 131 may be accommodated in the second guide portion 230, and the second guide portion 230 may be disposed in the stepped portion 330 of the OIS housing 300.

[0316] A fifth guide groove g5 may be formed in the upper surface of the OIS housing 300, and a sixth guide groove g6 may be formed in the lower surface of the OIS housing 300. The stepped portion 330 of the OIS housing 300 may have a stepped shape on the upper surface of the OIS housing 300, and the first guide portion 131 and the second guide portion 230 disposed on the stepped portion 330 of the OIS housing 300 may extend in the optical axis (Z-axis) direction to the area below the upper surface of the OIS housing 300.

[0317] In other words, the lower surface of the second guide portion 230 in the AF housing 200 can be located below the second spherical unit B2 disposed on the upper surface of the OIS housing 300 in the optical axis (Z axis) direction.

[0318] Furthermore, the lower surface of the second guide portion 230 in the AF housing 200 can be located below the third spherical unit B3 disposed on the lower surface of the OIS housing 300 in the optical axis (Z axis) direction.

[0319] Furthermore, the first ball unit B1 can be disposed between the first guide portion 131 and the second guide portion 230, and among the plurality of balls included in the first ball unit B1, the ball disposed at the lowest position in the optical axis (Z axis) direction can therefore be located below the upper surface of the OIS housing 300 in the optical axis (Z axis) direction.

[0320] Furthermore, when viewed from the first axis (X-axis) direction, the center of the sphere located at the bottom in the optical axis (Z-axis) direction among the multiple spheres included in the first sphere unit B1 can be located between the center of the second sphere unit B2 and the center of the third sphere unit B3.

[0321] According to the embodiments of the present disclosure, the camera module 1 can detect the position of the moving frame 400 in a direction perpendicular to the optical axis (Z-axis).

[0322] For this purpose, a fourth position sensor 715 and a fifth position sensor 735 can be provided. The fourth position sensor 715 can be disposed in the movable frame 400 facing the fourth magnet 711, and the fifth position sensor 735 can be disposed in the movable frame 400 facing the fifth magnet 731. The fourth position sensor 715 and the fifth position sensor 735 can be Hall sensors.

[0323] The fifth position sensor 735 may include two Hall sensors. For example, the fifth magnet 731 may include two magnets spaced apart from each other in a direction perpendicular to the direction in which the fifth magnet 731 generates a driving force (e.g., the direction of the second axis (Y-axis)), and the fifth position sensor 735 may include two Hall sensors facing the two magnets.

[0324] The rotation of the moving frame 400 can be detected by two Hall sensors facing the fifth magnet 731.

[0325] Rotational force can be intentionally generated by using the deviation generated in the driving force of the third sub-drive section 710 and the driving force of the fourth sub-drive section 730, the resultant force of the third sub-drive section 710 and the fourth sub-drive section 730, the two magnets and two coils included in the fourth sub-drive section 730, or any other suitable technique.

[0326] The sixth guide groove g6 may have a polygonal or circular shape, and its size is larger than the diameter of the plurality of balls included in the third ball unit B3. The plurality of balls included in the third ball unit B3 disposed in the sixth guide groove g6 may roll freely in a direction perpendicular to the optical axis (Z axis).

[0327] Therefore, the movable frame 400 can rotate about the optical axis (Z-axis) or any axis parallel to the optical axis (Z-axis) while being supported by the third ball unit B3.

[0328] Furthermore, when the camera module 1 requires linear motion without rotation, the unexpected rotational force can be counteracted by controlling the driving force of the third sub-drive section 710 and / or the driving force of the fourth sub-drive section 730.

[0329] Reference Figures 13 to 17The fourth coil 713 and the fifth coil 733 can be disposed within the movable frame 400, and a wiring pattern 410 can also be disposed within the movable frame 400. The wiring pattern 410 can be connected to the fourth coil 713 and the fifth coil 733. Furthermore, the wiring pattern 410 of the movable frame 400 can also be connected to the sensor substrate 800. Therefore, the fourth coil 713 and the fifth coil 733 can receive power through the wiring pattern 410 disposed within the movable frame 400.

[0330] That is, the camera module 1 according to the embodiments of the present disclosure may not include a separate printed circuit board for supplying power to the third drive section 700, and power may be supplied to the third drive section 700 by including wiring pattern 410 in the moving frame 400 itself.

[0331] The wiring pattern 410 can be integrally attached to the movable frame 400 by insertion injection molding. For example, the wiring pattern 410 can be manufactured integrally with the movable frame 400 by injecting resin material into the mold while the wiring pattern 410 is being set in the mold.

[0332] According to embodiments of the present disclosure, the camera module 1 may undergo at least two injections during the manufacturing of the movable frame 400.

[0333] When the pattern width is minimized to reduce its size, the rigidity of the wiring pattern 410 may be insufficient, and therefore it is difficult to fix the position of the wiring pattern 410 during insertion injection.

[0334] Therefore, a primary injection molded product (e.g., a first frame 420) integral with the wiring pattern 410 can be manufactured by a primary insertion injection molding process, and a secondary injection molded product (e.g., a second frame 440) integral with the primary injection molded product can be manufactured by a second insertion injection molding process, thereby manufacturing a movable frame 400 having the wiring pattern 410 therein.

[0335] Because two insertion injection molding processes are performed, a boundary line BL (see [reference needed]) can be formed between the first frame 420 (i.e., the primary injection molded product) and the second frame 440 (i.e., the secondary injection molded product). Figure 16 ).

[0336] The fourth coil 713, the fifth coil 733, the fourth position sensor 715, and the fifth position sensor 735 can be mounted in the first frame 420 (i.e., the master injection molded product). The fourth coil 713, the fifth coil 733, the fourth position sensor 715, and the fifth position sensor 735 can be connected to the wiring pattern 410 located in the first frame 420.

[0337] The wiring pattern 410 may include a wiring portion 411 and a terminal portion 413. The wiring portion 411 may be located within the first frame 420, and the terminal portion 413 may be exposed outside the first frame 420. Furthermore, the terminal portion 413 may also be exposed outside the second frame 440. The terminal portion 413 of the wiring pattern 410 may be connected to the sensor substrate 800, and thus power can be applied to the fourth coil 713, the fifth coil 733, the fourth position sensor 715, and the fifth position sensor 735 via the wiring pattern 410.

[0338] A sixth guide groove g6, in which the third ball unit B3 is disposed, can be formed in the second frame 440. The third ball unit B3 can be made of ceramic material and the second frame 440 can be made of plastic material, and therefore, there is a risk that the sixth guide groove g6 may be damaged due to their different hardness.

[0339] Therefore, a support pad 430 can be provided on the bottom surface of the sixth guide groove g6 to prevent damage to the sixth guide groove g6, and the support pad 430 can be inserted into the injection molding process during the second insertion injection molding process to become integral with the second frame 440. The support pad 430 can be made of stainless steel.

[0340] The support pad 430 can form the bottom surface of the sixth guide groove g6. Therefore, the third ball unit B3 can roll contact with the support pad 430.

[0341] A fourth and a fifth magnetic yoke (not shown) may be disposed in the movable frame 400. The fourth and fifth magnetic yokes can provide attractive forces such that the OIS housing 300 and the movable frame 400 remain in contact with the third spherical unit B3.

[0342] The fourth and fifth magnetic yokes can be inserted into the injection molding process in the same manner as the wiring pattern 410 to become integral with the first frame 420.

[0343] The fourth and fifth magnetic yokes can be configured to face the fourth magnet 711 and the fifth magnet 731 in the direction of the optical axis (Z axis).

[0344] The attractive force can act between the fourth yoke and the fourth magnet 711 and between the fifth yoke and the fifth magnet 731 in the direction of the optical axis (Z-axis).

[0345] Therefore, the movable frame 400 can be pressed against the OIS housing 300, and the OIS housing 300 and the movable frame 400 can thus remain in contact with the third ball unit B3.

[0346] The fourth and fifth magnetic yokes can each be made of materials that generate attractive forces between the fourth and fifth magnetic yokes and the fourth magnet 711 and the fifth magnet 731. For example, the fourth and fifth magnetic yokes can each be made of magnetic materials.

[0347] Figure 18 This is a perspective view of a sensor substrate according to an embodiment of the present disclosure. Figure 19 This is a plan view of the first optical image stabilization (OIS) substrate of the sensor substrate. Figure 20 This is a bottom view of the second optical image stabilization (OIS) substrate.

[0348] Reference Figure 18 The sensor substrate 800 may include an AF substrate 810, a first OIS substrate 830, and a second OIS substrate 850.

[0349] The first OIS substrate 830 may include a first moving portion 831, a first fixing portion 835, and a first connecting portion 833. The first OIS substrate 830 may be a radio frequency printed circuit board (RF PCB).

[0350] The first moving part 831 can be connected to the AF housing 200. For example, the first moving part 831 can be connected to the flange portion 250 of the AF housing 200. The second coil 613 and the third coil 633 of the second drive part 600 can be disposed on one surface of the first moving part 831, and the second yoke and the third yoke can be disposed on the other surface of the first moving part 831.

[0351] The first moving part 831 may be a moving member that can move together with the AF housing 200 during optical image stabilization. The first moving part 831 may be a rigid printed circuit board (PCB).

[0352] The first fixed portion 835 can be attached to the OIS housing 300 or the outer casing 930. The first fixed portion 835 can be a fixed member that does not move during optical image stabilization. The first fixed portion 835 can be a rigid PCB.

[0353] The first connecting portion 833 can be disposed between the first moving portion 831 and the first fixed portion 835, and can connect the first moving portion 831 and the first fixed portion 835 to each other. The first connecting portion 833 can be a flexible PCB. When the first moving portion 831 moves, the first connecting portion 833 disposed between the first moving portion 831 and the first fixed portion 835 can be bent.

[0354] The first connecting portion 833 may extend along at least a portion of the periphery of the first moving portion 831. The first connecting portion 833 may include a plurality of slits, each slit passing through the first connecting portion 833 in the optical axis direction. The plurality of slits may each be positioned with a gap between the first moving portion 831 and the first fixed portion 835. Therefore, the first connecting portion 833 may include a plurality of bridging members spaced apart from each other by the plurality of slits. The plurality of bridging members may extend along the periphery of the first moving portion 831.

[0355] The first connecting portion 833 may include a first support portion 837 and a second support portion 839. The first connecting portion 833 may be connected to the first movable portion 831 via the first support portion 837. Furthermore, the first connecting portion 833 may be connected to the first fixed portion 835 via the second support portion 839.

[0356] For example, a first support portion 837 may be contacted and connected to a first movable portion 831, and spaced apart from a first fixed portion 835. Furthermore, a second support portion 839 may be contacted and connected to the first fixed portion 835, and spaced apart from the first movable portion 831.

[0357] For example, the first support portion 837 may extend in a first axial direction (or X-axis direction) to connect the plurality of bridging members of the first connecting portion 833 and the first moving portion 831 to each other. In an embodiment, the first support portion 837 may include two support portions disposed opposite to each other in the first axial direction (X-axis direction).

[0358] The second support portion 839 may extend in the second axial direction (Y-axis direction) to connect the plurality of bridging members of the first connecting portion 833 and the first fixing portion 835 to each other. In an embodiment, the second support portion 839 may include a support portion.

[0359] Therefore, the first moving part 831 can move in a direction perpendicular to the optical axis (Z-axis) while being supported by the first connecting part 833, or rotate about the optical axis (Z-axis) or any axis parallel to the optical axis (Z-axis).

[0360] In this embodiment, when the image sensor S moves in the first axial direction (X-axis direction), the plurality of bridging members connected to the first support portion 837 can be bent. Furthermore, when the image sensor S moves in the second axial direction (Y-axis direction), the plurality of bridging members connected to the second support portion 839 can be bent. Additionally, when the image sensor S rotates, the plurality of bridging members connected to the first support portion 837 and the plurality of bridging members connected to the second support portion 839 can be bent together.

[0361] The AF substrate 810 can extend from the first OIS substrate 830 in the optical axis (Z-axis) direction. For example, the AF substrate 810 can be bent in the optical axis (Z-axis) direction from one side of the first OIS substrate 830 (e.g., one side of the first moving portion 831). The AF substrate 810 can be coupled to the AF housing 200, the first coil 530 can be disposed on one surface of the AF substrate 810, and the first magnetic yoke 550 can be disposed on the other surface of the AF substrate 810.

[0362] The second OIS substrate 850 may include a second moving portion 851, a second fixing portion 855, and a second connecting portion 853. The second OIS substrate 850 may be an RF PCB.

[0363] The image sensor S can be mounted on the second movable part 851. The second movable part 851 can be coupled to the lower surface of the movable frame 400. For example, the area of ​​the second movable part 851 can be larger than the area of ​​the image sensor S, and a portion of the second movable part 851 outside the image sensor S can be coupled to the lower surface of the movable frame 400.

[0364] The second moving part 851 may be a moving component that can move together with the moving frame 400 during optical image stabilization. The second moving part 851 may be a rigid PCB.

[0365] The second fixing portion 855 can be attached to the lower surface of the OIS housing 300. The second fixing portion 855 can be a fixed member that does not move during optical image stabilization. The second fixing portion 855 can be a rigid PCB. The second fixing portion 855 can be bent and extended from the first fixing portion 835 of the first OIS substrate 830.

[0366] The second connecting portion 853 can be disposed between the second moving portion 851 and the second fixed portion 855, and can connect the second moving portion 851 and the second fixed portion 855 to each other. The second connecting portion 853 can be a flexible PCB. When the second moving portion 851 moves, the second connecting portion 853 disposed between the second moving portion 851 and the second fixed portion 855 can be bent.

[0367] The second connecting portion 853 may extend along the periphery of the second moving portion 851. The second connecting portion 853 may include a plurality of slits passing through it in the optical axis direction. Each of the plurality of slits may be spaced apart between the second moving portion 851 and the second fixed portion 855. Therefore, the second connecting portion 853 may include a plurality of bridging members spaced apart from each other by the plurality of slits. The plurality of bridging members may extend along the periphery of the second moving portion 851.

[0368] The second connecting portion 853 may include a third support portion 857 and a fourth support portion 859. The second connecting portion 853 can be connected to the second fixed portion 855 via the third support portion 857. Furthermore, the second connecting portion 853 can be connected to the second movable portion 851 via the fourth support portion 859.

[0369] For example, a third support portion 857 may be contacted and connected to the second fixed portion 855, and spaced apart from the second movable portion 851. Furthermore, a fourth support portion 859 may be contacted and connected to the second movable portion 851, and spaced apart from the second fixed portion 855.

[0370] For example, the third support portion 857 may extend in the first axial direction (or the X-axis direction) to connect the plurality of bridging members of the second connecting portion 853 and the second fixing portion 855 to each other. In an embodiment, the third support portion 857 may include two support portions disposed opposite to each other in the first axial direction (X-axis direction).

[0371] The fourth support portion 859 may extend in the second axial direction (Y-axis direction) to connect the plurality of bridging members of the second connecting portion 853 and the second moving portion 851 to each other. In an embodiment, the fourth support portion 859 may include two support portions disposed opposite to each other in the second axial direction (Y-axis direction).

[0372] Therefore, the second moving part 851 can move in a direction perpendicular to the optical axis (Z-axis) while being supported by the second connecting part 853, or rotate about the optical axis (Z-axis) or any axis parallel to the optical axis (Z-axis).

[0373] In this embodiment, when the image sensor S moves in the first axial direction (X-axis direction), the plurality of bridging members connected to the third support portion 857 can be bent. Furthermore, when the image sensor S moves in the second axial direction (Y-axis direction), the plurality of bridging members connected to the fourth support portion 859 can be bent. Additionally, when the image sensor S rotates, the plurality of bridging members connected to the third support portion 857 and the plurality of bridging members connected to the fourth support portion 859 can be bent together.

[0374] The first OIS substrate 830 and the second OIS substrate 850 can be connected to each other. For example, the first fixing portion 835 of the first OIS substrate 830 can be connected to the second fixing portion 855 of the second OIS substrate 850.

[0375] In this embodiment, the AF substrate 810, the first OIS substrate 830, and the second OIS substrate 850 are described as a single unit. However, this configuration is merely an example. The AF substrate 810, the first OIS substrate 830, and the second OIS substrate 850 can also be configured as separate components and electrically connected to each other.

[0376] Reference Figure 2 The base 910 can be connected to the lower part of the sensor substrate 800.

[0377] The base 910 can be attached to the sensor substrate 800 to cover the lower part of the sensor substrate 800. The base 910 can be used to prevent external foreign objects from being introduced into the camera module 1 through the gap between the second moving part 851 and the second fixed part 855 of the sensor substrate 800.

[0378] Figure 21 It is along Figure 1 The line XXI-XXI' intercepted in the middle Figure 1 A cross-sectional view of the camera module; and Figure 22 It is along Figure 1 The line XXII-XXII' in the middle is intercepted Figure 1 A cross-sectional view of the camera module.

[0379] Reference Figure 21 and Figure 22 In the camera module 1 according to an embodiment of the present disclosure, the support portion 130 can move relative to the AF housing 200 in the optical axis (Z-axis) direction during autofocus. The lens barrel 110 can be coupled to the support portion 130, and therefore when the support portion 130 moves, the lens barrel 110 can also move together with the support portion 130 in the optical axis (Z-axis) direction.

[0380] During optical image stabilization, the AF housing 200 can move relative to the OIS housing 300 in a direction perpendicular to the optical axis (Z-axis).

[0381] The lens module 100 can be housed in the AF housing 200, and the first ball unit B1 can be disposed between the AF housing 200 and the lens module 100.

[0382] The first ball unit B1 can be disposed in the first guide groove portion G1 and the second guide groove portion G2 so as to have restricted movement in the direction perpendicular to the optical axis (Z-axis) (i.e., the first ball unit B1 can be configured to move in the direction perpendicular to the optical axis (Z-axis)). Therefore, when the AF housing 200 moves in the direction perpendicular to the optical axis (Z-axis), the lens module 100 can also move together with the AF housing 200 in the direction perpendicular to the optical axis (Z-axis).

[0383] Furthermore, during optical image stabilization, the moving frame 400 can move relative to the OIS housing 300 in a direction perpendicular to the optical axis (Z-axis). The sensor substrate 800 on which the image sensor S is mounted can be coupled to the moving frame 400, and when the moving frame 400 moves in a direction perpendicular to the optical axis (Z-axis), the image sensor S can also move together with the moving frame 400 in a direction perpendicular to the optical axis (Z-axis).

[0384] In one embodiment, the AF housing 200 may be disposed on one side of the OIS housing 300 in the optical axis (Z-axis) direction, and the movable frame 400 may be disposed on the other side of the OIS housing 300 in the optical axis (Z-axis) direction.

[0385] The AF housing 200 can move relative to the OIS housing 300 to perform optical image stabilization, and the moving frame 400 can also move relative to the OIS housing 300 to perform optical image stabilization.

[0386] The second drive section 600, which provides driving force to the AF housing 200, and the third drive section 700, which provides driving force to the moving frame 400, can operate independently of each other, and thus either the AF housing 200 or the moving frame 400 can move to perform optical image stabilization.

[0387] Furthermore, both the AF housing 200 and the movable frame 400 can be moved to perform optical image stabilization. In this case, the AF housing 200 and the movable frame 400 can move in opposite directions to each other.

[0388] For example, when the AF housing 200 moves in the positive first axis (X-axis) direction (or +X-axis direction), the moving frame 400 can move in the negative first axis (X-axis) direction (or -X-axis direction). Furthermore, when the AF housing 200 moves in the positive second axis (Y-axis) direction (or +Y-axis direction), the moving frame 400 can move in the negative second axis (Y-axis) direction (or -Y-axis direction).

[0389] As described above, the AF housing 200 and the moving frame 400 can move in opposite directions, thereby maximizing the optical image stabilization effect even when moving a small distance. That is, the optical image stabilization effect can be improved even when the magnitude of the driving force used to move the AF housing 200 and the moving frame 400 is reduced.

[0390] Furthermore, even when the lens module 100 moves in the optical axis (Z-axis) direction during autofocus, the relative positions of the magnet and coil in the second drive section 600 and the relative positions of the magnet and coil in the third drive section 700 do not change, and thus the driving force for optical image stabilization can be precisely controlled.

[0391] Furthermore, even when one or both of the AF housing 200 and the moving frame 400 move in a direction perpendicular to the optical axis (Z-axis) during optical image stabilization, the relative positions of the magnet and coil of the first drive section 500 do not change, and thus the driving force used for autofocus can be precisely controlled.

[0392] Figure 23 This is a schematic exploded perspective view of a camera module according to another embodiment of the present disclosure.

[0393] Figure 23 Another embodiment shown in the reference Figures 1 to 22 The described implementation differs in the shape of the fifth guide groove g5 and the sixth guide groove g6.

[0394] For example, the fifth guide groove g5 can extend in the direction of the first axis (X-axis), and the sixth guide groove g6 can extend in the direction of the second axis (Y-axis). Furthermore, the cross-sections of the fifth guide groove g5 and the sixth guide groove g6 can each have a "V" shape.

[0395] The fifth guide groove g5 can be formed in one or two surfaces of the AF housing 200 and the OIS housing 300 that face each other in the optical axis (Z axis) direction.

[0396] The sixth guide groove g6 can be formed on one or two surfaces of the OIS housing 300 and the moving frame 400 that face each other in the optical axis (Z axis) direction.

[0397] The length direction of the fifth guide groove g5 can be parallel to the short side of the image sensor S. Furthermore, the length direction of the sixth guide groove g6 can be parallel to the long side of the image sensor S.

[0398] The second ball unit B2, disposed in the fifth guide groove g5, can roll in the first axis (X-axis) direction and has restricted movement in directions other than the first axis (X-axis) direction. Furthermore, the third ball unit B3, disposed in the sixth guide groove g6, can roll in the second axis (Y-axis) direction and has restricted movement in directions other than the second axis (Y-axis) direction.

[0399] Therefore, during optical image stabilization, the AF housing 200 can move relative to the OIS housing 300 in the first axis (X-axis) direction, and the moving frame 400 can move relative to the OIS housing 300 in the second axis (Y-axis) direction.

[0400] In other words, Figure 23In another embodiment, optical image stabilization in the first axis (X-axis) direction can be achieved by the movement of the AF housing 200, and optical image stabilization in the second axis (Y-axis) direction can be achieved by the movement of the moving frame 400.

[0401] Figure 24 This is a schematic exploded perspective view of a camera module according to another embodiment of the present disclosure.

[0402] Figure 24 The embodiment shown differs from the embodiment described above in the configuration for supporting the movement of the AF housing 200 and the movable frame 400.

[0403] For example, in Figure 24 In the embodiment shown, a plurality of first suspension lines W1 may be disposed between the AF housing 200 and the OIS housing 300, and a plurality of second suspension lines W2 may be disposed between the OIS housing 300 and the movable frame 400.

[0404] One end of each of the plurality of first suspension wires W1 can be connected to the AF housing 200, and the other end of each of the plurality of first suspension wires W1 can be connected to the OIS housing 300. Therefore, the AF housing 200 can be movably supported by the plurality of first suspension wires W1.

[0405] Furthermore, one end of each of the plurality of second suspension wires W2 can be connected to the OIS housing 300, and the other end of each of the plurality of second suspension wires W2 can be connected to the movable frame 400. Therefore, the movable frame 400 can be movably supported by the plurality of second suspension wires W2.

[0406] Figure 25 This is a schematic cross-sectional view of a camera module according to another embodiment of the present disclosure. Figure 26 yes Figure 25 A three-dimensional view of the second and third drive sections of the camera module.

[0407] Reference Figures 1 to 22 In the described embodiment, the AF housing 200 can be moved by the second drive portion 600, and the moving frame 400 can be moved by the third drive portion 700. The second drive portion 600 may include a second magnet 611, a second coil 613, a third magnet 631, and a third coil 633, and the third drive portion 700 may include a fourth magnet 711, a fourth coil 713, a fifth magnet 731, and a fifth coil 733. That is, the magnets included in the second drive portion 600 and the third drive portion 700 can be configured as individual magnets.

[0408] However, in Figure 25In the embodiment shown, the magnet of the second drive section 600 and the magnet of the third drive section 700 can be the same magnet.

[0409] For example, the first common magnet 650 and the second common magnet 670 can be installed in the OIS housing 300.

[0410] The first common magnet 650 can interact with the second coil 613 to generate a driving force for moving the AF housing 200, and the second common magnet 670 can interact with the third coil 633 to generate a driving force for moving the AF housing 200.

[0411] Furthermore, the first common magnet 650 can interact with the fourth coil 713 to generate a driving force for moving the moving frame 400, and the second common magnet 670 can interact with the fifth coil 733 to generate a driving force for moving the moving frame 400.

[0412] The first common magnet 650 and the second common magnet 670 can each be magnetized to have an N pole, a neutral region, and an S pole in a direction perpendicular to the optical axis (Z axis).

[0413] The second coil 613 and the third coil 633 can be disposed on the AF housing 200. Furthermore, the second coil 613 can face the first common magnet 650 in the first axis (X-axis) direction. The second coil 613 can face either the N pole or the S pole of the first common magnet 650. Therefore, a driving force can be generated in the direction in which the first common magnet 650 and the second coil 613 face each other (e.g., the first axis (X-axis) direction).

[0414] The third coil 633 can face the second common magnet 670 in the direction of the second axis (Y-axis). The third coil 633 can face the N pole or S pole of the second common magnet 670. Therefore, a driving force can be generated in the direction in which the second common magnet 670 and the third coil 633 face each other (e.g., the direction of the second axis (Y-axis)).

[0415] The fourth coil 713 and the fifth coil 733 can be disposed within the movable frame 400. Furthermore, the fourth coil 713 can face the first common magnet 650 in the optical axis (Z-axis) direction. The fourth coil 713 can face the N and S poles of the first common magnet 650. Therefore, a driving force can be generated in a direction perpendicular to the optical axis (Z-axis) direction in which the first common magnet 650 and the fourth coil 713 face each other (e.g., the first axis (X-axis) direction).

[0416] Furthermore, the fifth coil 733 can face the second common magnet 670 in the optical axis (Z-axis) direction. The fifth coil 733 can face the N pole and S pole of the second common magnet 670. Therefore, a driving force can be generated in a direction perpendicular to the optical axis (Z-axis) direction in which the second common magnet 670 and the fifth coil 733 face each other (e.g., the second axis (Y-axis) direction).

[0437] For example, the first drive current I1, the second drive current I2, and the third drive current I3 can be different from each other, and can be generated by a current generating circuit that can adjust the generated current.
