[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2025-0051104, filed on April 18, 2025, with the Korean Intellectual Property Office, and Korean Patent Application No. 10-2026-0040858, filed on March 6, 2026, 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] Recently, camera modules have been used in mobile communication terminals such as smartphones, tablet PCs, and laptop computers. These camera modules are equipped with actuators that have focus adjustment capabilities in order to generate high-resolution images.

[0005] As the thickness of mobile communication terminals gradually decreases, the thickness of camera modules used in mobile communication terminals also needs to be reduced accordingly.

[0006] However, due to the various factors required to capture high-resolution images, it is difficult to reduce the thickness of the camera module.

[0007] In particular, when the thickness of the camera module is reduced, it becomes difficult to ensure operational stability during focus adjustment. Summary of the Invention

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

[0051] 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 of 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.

[0052] The features described herein may be implemented in different 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, apparatus, and / or systems described herein will be apparent upon understanding the disclosure of this application.

[0053] 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.

[0054] As used herein, the term “and / or” includes any one of the associated listed items and any combination of any two or more items.

[0055] 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.

[0056] Spatial relative terms such as “above,” “above,” “below,” and “under” 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 “under” 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.

[0057] 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 terms “a,” “an,” and “the” are intended to include plural expressions as well. The terms “comprising,” “including,” and “having” indicate the presence of the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not preclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0058] In this specification, the optical axis (Z-axis) direction may refer to the direction in which the optical axis (Z-axis) of the lens module 200 extends upward and downward, or the direction in which it is parallel to the optical axis (Z-axis).

[0059] The first axis (X-axis) direction can refer to the direction perpendicular to the optical axis (Z-axis) direction, and the second axis (Y-axis) direction can refer to the direction perpendicular to both the optical axis (Z-axis) direction and the first axis (X-axis) direction.

[0060] This disclosure relates to a camera module that can be installed in a portable electronic device such as a mobile communication terminal, a smartphone, or a tablet PC.

[0061] Figure 1 This is a perspective view illustrating a camera module according to an embodiment of the present disclosure, and Figure 2 yes Figure 1 An exploded stereoscopic view of the camera module.

[0062] Reference Figure 1 and Figure 2 According to an embodiment of the present disclosure, the camera module 1 includes an optical module and a housing 110.

[0063] In this specification, the optical module may be understood to include either or both of the lens module 200 and the image sensor module 700. For example, in one embodiment, the optical module may refer to the lens module 200, and in another embodiment, the optical module may refer to the image sensor module 700.

[0064] The lens module 200 includes one or more lenses 210 and a lens barrel 220 that houses one or more lenses 210.

[0065] The lens barrel 220 may have a hollow cylindrical shape, and one or more lenses 210 may be disposed within the lens barrel 220.

[0066] When multiple lenses 210 are provided, the multiple lenses 210 can be installed in the lens barrel 220 in the direction of the optical axis (Z axis).

[0067] The camera module 1 may also include an OIS carrier 330. In this case, the lens barrel 220 may be attached to the OIS carrier 330. For reference, "OIS" can refer to optical image stabilization.

[0068] The OIS support 330 can move relative to the housing 110 in a direction perpendicular to the optical axis (Z-axis). Since the lens barrel 220 is connected to the OIS support 330, the lens barrel 220 can move together with the OIS support 330 in a direction perpendicular to the optical axis (Z-axis).

[0069] In other words, the lens module 200 and the OIS carrier 330 can move in a direction perpendicular to the optical axis (Z-axis) to perform image stabilization during image capture.

[0070] The camera module 1 may also include an AF support unit 300. The AF support unit 300 is disposed in the housing 110 and is movable relative to the housing 110 in the optical axis (Z-axis) direction. The lens module 200 and the OIS support unit 330 may be disposed in the AF support unit 300. Therefore, the lens module 200, the OIS support unit 330, and the AF support unit 300 can move together in the optical axis (Z-axis) direction.

[0071] In other words, the focus can be adjusted by changing the distance between the lens module 200 and the image sensor 710.

[0072] For reference, "AF" can refer to autofocus.

[0073] The housing 110 has an open shape at the top and bottom. The AF support 300 is disposed in the internal space of the housing 110, and the lens module 200 and the OIS support 330 can be accommodated in the AF support 300.

[0074] The outer casing 120 is attached to the housing 110 to surround the outer surface of the housing 110 and to protect the internal components of the camera module 1.

[0075] The image sensor module 700 is a device that converts light incident through the lens module 200 into electrical signals.

[0076] As an example, the image sensor module 700 may include an image sensor 710 and a printed circuit board 720 connected to the image sensor 710, and may also include an infrared filter (not shown).

[0077] An infrared filter can be used to block light in the infrared region from passing through the lens module 200 and incident onto it.

[0078] Image sensor 710 converts incident light through lens module 200 and filter into electrical signals. For example, image sensor 710 may be a charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) device.

[0079] The image sensor 710 has an imaging surface on which light passing through the lens module 200 is received.

[0080] The electrical signal converted by the image sensor 710 is output as an image through the display unit of the portable electronic device.

[0081] The image sensor 710 is fixed to the printed circuit board 720 and electrically connected to the printed circuit board 720 via wire bonding.

[0082] The image sensor module 700 is located below the housing 110.

[0083] The stop 130 is connected to the AF support portion 300. The stop 130 is connected to the AF support portion 300 so as to cover at least a portion of the upper surface of the OIS support portion 330.

[0084] The stop 130 can prevent the OIS carrier 330 from separating from the AF carrier 300 due to external impact or other interference.

[0085] The resilient buffer member 131 can be attached to each corner portion of the stop member 130.

[0088] Figures 8 to 10 yes Figure 3 Plan view of the first and second actuators.

[0089] The camera module 1 may include a first actuator 400. The lens module 200 may be moved in the direction of the optical axis (Z-axis) via the first actuator 400.

[0090] For example, the first actuator 400 can generate a driving force in the optical axis (Z-axis) direction to move the AF support 300 in the optical axis (Z-axis) direction. Since the lens module 200 and the OIS support 330 are disposed in the AF support 300, the AF support 300, the lens module 200 and the OIS support 330 can move together in the optical axis (Z-axis) direction by the driving force of the first actuator 400.

[0091] The first actuator 400 includes an AF magnet 410 and an AF coil 430. The AF magnet 410 and the AF coil 430 can be arranged to face each other in a direction perpendicular to the optical axis (Z-axis). For example, the AF magnet 410 and the AF coil 430 can face each other in the direction of the first axis (X-axis).

[0092] One of the AF magnet 410 and the AF coil 430 may be disposed on the AF support portion 300, and the other of the AF magnet 410 and the AF coil 430 may be disposed on the housing 110. In the following description, an embodiment based on the AF magnet 410 being disposed on the AF support portion 300 will be given.

[0093] The AF magnet 410 is mounted on the AF support portion 300. As an example, the AF magnet 410 may be mounted on the side surface of the AF support portion 300 facing the first axis (X-axis).

[0094] The AF magnet 410 can be magnetized such that one surface of the AF magnet 410 (e.g., the surface facing the AF coil 430) has both a N pole and a S pole. As an example, the N pole, the neutral region, and the S pole can be sequentially arranged on one surface of the AF magnet 410 facing the AF coil 430 in the optical axis (Z-axis) direction.

[0095] In this specification, the first polarity may refer to the N pole or the S pole, and the second polarity may refer to the polarity opposite to the first polarity.

[0096] The AF coil 430 is configured to face the AF magnet 410. For example, the AF coil 430 may be configured to face the AF magnet 410 in a direction perpendicular to the optical axis (Z-axis) (in this embodiment, the first axis (X-axis) direction).

[0097] An AF coil 430 is disposed on a substrate 140, and the substrate 140 is mounted on a housing 110, such that the AF magnet 410 and the AF coil 430 face each other in a direction perpendicular to the optical axis (Z-axis). As an example, the AF coil 430 may be disposed on one surface of the substrate 140. The substrate 140 is mounted on a side surface of the housing 110, such that the AF magnet 410 and the AF coil 430 face each other in a direction perpendicular to the optical axis (Z-axis).

[0098] An opening is provided in the side surface of the housing 110, and the AF coil 430 provided on the substrate 140 can directly face the AF magnet 410 through the opening.

[0099] In an embodiment, the housing 110 includes a first side surface 111, a second side surface 112, a third side surface 113, and a fourth side surface 114. Each side surface may extend from the bottom surface of the housing 110 in the direction of the optical axis (Z-axis).

[0100] The first side surface 111 and the second side surface 112 are disposed opposite to each other, and the third side surface 113 and the fourth side surface 114 are disposed opposite to each other.

[0101] The first side surface 111 and the second side surface 112 are perpendicular to the third side surface 113 and the fourth side surface 114.

[0102] The AF coil 430 is disposed on the first side surface 111, and the opening is disposed on the first side surface 111.

[0103] During focus adjustment, the AF magnet 410 is a moving member mounted on the AF support 300 and moving together with the AF support 300 in the optical axis (Z axis) direction, and the AF coil 430 is a fixed member fixed to the substrate 140.

[0104] When power is applied to the AF coil 430, the AF support 300 can move in the direction of the optical axis (Z axis) by the electromagnetic force generated between the AF magnet 410 and the AF coil 430.

[0105] Since the lens module 200 and the OIS support 330 are housed in the AF support 300, the lens module 200 and the OIS support 330 also move in the optical axis (Z-axis) direction through the movement of the AF support 300.

[0106] The first guide unit G1 is disposed between the AF support part 300 and the housing 110. The first guide unit G1 can guide the movement of the AF support part 300.

[0107] The first guide unit G1 includes a first support guide g1 and a second support guide g2 spaced apart from each other in a direction perpendicular to the optical axis (Z-axis) (in this embodiment, the second axis (Y-axis) direction).

[0108] In this embodiment, the first guiding unit G1 may include a plurality of balls. When the AF bearing portion 300 moves in the optical axis (Z-axis) direction, the plurality of balls may roll in the optical axis (Z-axis) direction.

[0109] For example, the first support guide g1 and the second support guide g2 may each include one or more balls.

[0110] The first support guide g1 can be used as the main guide for the movement of the lens module 200 in the optical axis (Z axis) direction.

[0111] The second support guide g2 can be used as an auxiliary guide to support the movement of the lens module 200 in the optical axis (Z-axis) direction.

[0112] The second support guide g2 can be positioned between the opposite ends of the first support guide g1 in the optical axis (Z-axis) direction.

[0113] The first yoke 470 may be disposed on the housing 110. The first yoke 470 may be disposed at a position spaced apart from the AF magnet 410 in the first axis (X-axis) direction. For example, the AF coil 430 may be disposed on one surface of the substrate 140, and the first yoke 470 may be disposed on the other surface of the substrate 140.

[0114] The AF magnet 410 and the first yoke 470 can generate an attractive force between them. For example, the first yoke 470 can be made of a magnetic material. The attractive force acts between the AF magnet 410 and the first yoke 470 in a direction perpendicular to the optical axis (Z-axis) (in this embodiment, the first axis (X-axis) direction).

[0115] Therefore, the AF support 300 and housing 110 can remain in contact with the first guide unit G1 by the attraction generated between the AF magnet 410 and the first yoke 470.

[0116] The first guide groove gr1 can be formed in either or both of the AF support 300 and the housing 110.

[0117] For example, the first guide groove gr1 can be formed in each of the surfaces of the AF support portion 300 and the housing 110 that face each other.

[0118] The first guide groove gr1 extends in the direction of the optical axis (Z-axis). The first support guide g1 and the second support guide g2 are disposed in the first guide groove gr1.

[0119] The first support guide g1 and the second support guide g2 are spaced apart from each other in a direction perpendicular to the optical axis (Z-axis) (in this embodiment, the second axis (Y-axis) direction). The first support guide g1 includes a plurality of balls arranged in the optical axis (Z-axis) direction. The second support guide g2 includes fewer balls than the first support guide g1.

[0120] For example, the first support guide g1 includes two or more balls arranged in the optical axis (Z-axis) direction, and the second support guide g2 includes fewer balls than the first support guide g1. The number of balls can be varied, as long as the number of balls in the first support guide g1 is different from the number of balls in the second support guide g2.

[0121] In an embodiment, on the side surface of the AF support portion 300, the AF magnet 410 may be offset toward one side of the AF support portion 300 along the longitudinal direction of the AF magnet 410 (e.g., the direction of the first axis (X-axis)).

[0122] For example, refer to Figure 5 The AF magnet 410 can be configured to be closer to the first support guide g1 (main guide) than the second support guide g2 (auxiliary guide).

[0123] In this embodiment, the auxiliary yoke 471 may be disposed at a position facing the AF magnet 410. The auxiliary yoke 471 may be fixedly disposed relative to the housing 110. For example, the auxiliary yoke 471 may be disposed on the substrate 140 so as to face the AF magnet 410.

[0124] The auxiliary yoke 471 can be set in the hole of the AF coil 430.

[0125] The auxiliary yoke 471 can be positioned closer to the main guide than the auxiliary guide. For example, the auxiliary yoke 471 can be positioned closer to the first support guide g1 (main guide) with a larger number of balls than the second support guide g2 (auxiliary guide) with a smaller number of balls.

[0126] The auxiliary yoke 471 is made of a material that can generate an attractive force with the AF magnet 410.

[0127] Therefore, the combined force of the attraction generated between the AF magnet 410 and the first yoke 470 and the attraction generated between the AF magnet 410 and the auxiliary yoke 471 can be set to be closer to the main guide than the auxiliary guide.

[0128] In this embodiment, the camera module 1 can detect the position of the AF support 300 in the direction of the optical axis (Z axis).

[0129] For this purpose, a first position sensor 450 is provided. The first position sensor 450 is disposed on the substrate 140 so as to face the AF magnet 410. The first position sensor 450 may be a Hall sensor.

[0130] The camera module 1 can perform image stabilization during image capture by moving the lens module 200 in a direction perpendicular to the optical axis (Z-axis). To this end, the camera module 1 includes a second actuator 500 that moves the lens module 200 in a direction perpendicular to the optical axis (Z-axis).

[0131] The lens module 200 and the OIS carrier 330 can move together in a direction perpendicular to the optical axis (Z-axis) by the driving force generated by the second actuator 500.

[0132] For example, the lens module 200 and the OIS carrier 330 can move together in the first axis (X-axis) direction and the second axis (Y-axis) direction.

[0133] The second actuator 500 includes a first image stabilization actuator 510 and a second image stabilization actuator 520. The first image stabilization actuator 510 can generate a driving force in the direction of a first axis (X-axis), and the second image stabilization actuator 520 can generate a driving force in the direction of a second axis (Y-axis).

[0134] The first image stabilization actuator 510 includes a first OIS magnet 511 and a first OIS coil portion 512. The first OIS magnet 511 and the first OIS coil portion 512 may be arranged to face each other in the direction of a first axis (X-axis).

[0135] One of the first OIS magnet 511 and the first OIS coil portion 512 may be disposed on the OIS support portion 330, and the other of the first OIS magnet 511 and the first OIS coil portion 512 may be disposed on the housing 110. Hereinafter, an embodiment based on the first OIS magnet 511 being disposed on the OIS support portion 330 will be described.

[0136] The first OIS magnet 511 can be provided on the OIS support portion 330. For example, the first OIS magnet 511 can be mounted on the side surface of the OIS support portion 330.

[0137] The first OIS magnet 511 can be magnetized such that one of its surfaces has both an N pole and a S pole. As an example, the N pole, the neutral region, and the S pole can be sequentially arranged along the second axis (Y-axis) on one surface of the first OIS magnet 511. The first OIS magnet 511 has a shape having length in the second axis (Y-axis) direction.

[0138] Another surface of the first OIS magnet 511 can be magnetized to have a polarity opposite to that of one surface of the first OIS magnet 511.

[0139] The first OIS coil portion 512 can be configured to face the first OIS magnet 511. For example, the first OIS coil portion 512 can be configured to face the first OIS magnet 511 in the first axis (X-axis) direction.

[0140] The first OIS coil portion 512 can be disposed on the second side surface 112 of the housing 110. An opening can be disposed in the second side surface 112 of the housing 110.

[0141] The first OIS coil portion 512 may include two coils spaced apart from each other, and the two coils of the first OIS coil portion 512 may each have a perforated annular shape.

[0142] In an embodiment, the first OIS coil portion 512 may include a first sub-coil 512a and a second sub-coil 512b. The first sub-coil 512a and the second sub-coil 512b may be spaced apart from each other in the direction of the second axis (Y-axis).

[0143] Therefore, a separation space 512c can be formed between the first sub-coil 512a and the second sub-coil 512b (see [link]). Figures 8 to 10 ).

[0144] One of the two coils of the first OIS coil portion 512 can be configured to face the N pole on one surface of the first OIS magnet 511, and the other of the two coils of the first OIS coil portion 512 can be configured to face the S pole on one surface of the first OIS magnet 511.

[0145] For example, the polarity of the first OIS magnet 511 facing the first sub-coil 512a and the polarity of the first OIS magnet 511 facing the second sub-coil 512b can be different from each other.

[0146] Due to the polarity arrangement of the first OIS magnet 511 and the arrangement of the first OIS coil portion 512, magnetic field leakage can be prevented, and thus sufficient driving force can be generated even under low power conditions.

[0147] In this embodiment, the first OIS magnet 511 is configured as a single magnet, but the first OIS magnet 511 may also be configured to include multiple magnets. In this case, one surface of each of the multiple magnets may be configured to have a polarity.

[0148] During image stabilization, the first OIS magnet 511 is a movable component mounted on the OIS carrier 330, and the first OIS coil portion 512 is a fixed component fixed to the housing 110.

[0149] The first OIS magnet 511 and the first OIS coil portion 512 can generate a driving force in the direction in which the first OIS magnet 511 and the first OIS coil portion 512 face each other (e.g., the direction of the first axis (X-axis)).

[0150] When power is applied to the first OIS coil portion 512, the OIS carrier portion 330 and the lens module 200 can move in the direction of the first axis (X-axis) by the electromagnetic force generated between the first OIS magnet 511 and the first OIS coil portion 512.

[0151] The first OIS magnet 511 can be positioned at a location spaced apart from the AF magnet 410 in the first axis (X-axis) direction.

[0152] Furthermore, the two coils of the first OIS coil portion 512 can be positioned at a location spaced apart from the AF magnet 410 in the first axis (X-axis) direction. For example, the first sub-coil 512a and the second sub-coil 512b can be positioned spaced apart from the AF magnet 410 in the first axis (X-axis) direction.

[0153] When viewed in the first axis (X-axis) direction, the center of the AF magnet 410 in the second axis (Y-axis) direction can be spaced apart from the separation space 512c between the two coils of the first OIS coil portion 512 in the second axis (Y-axis) direction.

[0154] In other words, when viewed in the first axis (X-axis) direction, the center of the AF magnet 410 in the second axis (Y-axis) direction may not overlap with the separation space 512c between the two coils of the first OIS coil section 512.

[0155] For example, the separation space 512c is formed between the first sub-coil 512a and the second sub-coil 512b, and when viewed in the direction of the first axis (X-axis), the center of the AF magnet 410 in the direction of the second axis (Y-axis) can be set to be spaced apart from the separation space 512c in the direction of the second axis (Y-axis).

[0156] Reference Figure 8 The distance D1 between the separation space 512c between the first sub-coil 512a and the second sub-coil 512b and a surface of the second OIS magnet 521, which will be described later, in the second axis (Y-axis) direction can be less than the distance D2 between the center of the AF magnet 410 and a surface of the second OIS magnet 521 in the second axis (Y-axis) direction.

[0157] When viewed along the first axis (X-axis), the center of the AF magnet 410 and the center of the first OIS magnet 511 can be spaced apart from each other along the second axis (Y-axis).

[0158] The distance D2 between the center of the AF magnet 410 and a surface of the second OIS magnet 521 in the second axis (Y-axis) direction can be greater than the distance D3 between the center of the first OIS magnet 511 and a surface of the second OIS magnet 521 in the second axis (Y-axis) direction.

[0159] The center of the first OIS magnet 511 can be located in the neutral region between the N pole and the S pole on one surface of the first OIS magnet 511.

[0160] Reference Figure 9 The distance D4 between the center of the AF magnet 410 and the first support guide g1 in the second axis (Y axis) direction may be different from the distance D5 between the separation space 512c between the first sub-coil 512a and the second sub-coil 512b of the first OIS coil portion 512 and the first support guide g1 in the second axis (Y axis) direction.

[0161] For example, the distance D4 between the center of the AF magnet 410 and the first support guide g1 in the second axis (Y-axis) direction can be smaller than the distance D5 between the separation space 512c between the first sub-coil 512a and the second sub-coil 512b of the first OIS coil portion 512 and the first support guide g1 in the second axis (Y-axis) direction. That is, the center of the AF magnet 410 can be set closer to the first support guide g1 than the separation space 512c. Therefore, the operational stability during focus adjustment can be improved by setting the AF magnet 410 closer to the first support guide g1.

[0162] Reference Figure 10 The distance D6 between the center of the AF magnet 410 and the third side surface 113 of the housing 110 in the second axis (Y axis) direction may be different from the distance D7 between the separation space 512c between the first sub-coil 512a and the second sub-coil 512b of the first OIS coil portion 512 and the third side surface 113 of the housing 110 in the second axis (Y axis) direction.

[0163] For example, the distance D6 between the center of the AF magnet 410 and the third side surface 113 of the housing 110 in the second axis (Y-axis) direction can be less than the distance D7 between the partition space 512c between the first sub-coil 512a and the second sub-coil 512b of the first OIS coil portion 512 and the third side surface 113 of the housing 110 in the second axis (Y-axis) direction. That is, the center of the AF magnet 410 can be set closer to the third side surface 113 of the housing 110 than the partition space 512c.

[0164] Here, the third side surface 113 of the housing 110 can refer to the surface of the housing 110 that is closer to the AF magnet 410 among the side surfaces of the housing 110 that are perpendicular to the AF magnet 410.

[0165] Alternatively, the third side surface 113 of the housing 110 may refer to the side surface of the housing 110 opposite to the side surface of the housing 110 on which the second image stabilization actuator 520 is disposed. Alternatively, the third side surface 113 of the housing 110 may refer to the side surface of the housing 110 on which no coil is disposed.

[0166] The ratio of the length of the first OIS magnet 511 in the second axis (Y-axis) direction to the length of the AF magnet 410 in the second axis (Y-axis) direction is greater than or equal to 0.5 and less than or equal to 1.

[0167] When viewed along the first axis (X-axis), the center of the AF magnet 410 and the center of the lens barrel 220 can be spaced apart from each other along the second axis (Y-axis).

[0168] When viewed along the optical axis (Z-axis), the center of the AF magnet 410 can be positioned at a location spaced apart from the center of the imaging surface of the image sensor 710 along the first axis (X-axis) and the second axis (Y-axis).

[0169] The second image stabilization actuator 520 includes a second OIS magnet 521 and a second OIS coil portion 522. The second OIS magnet 521 and the second OIS coil portion 522 may be arranged to face each other in the direction of the second axis (Y-axis).

[0170] One of the second OIS magnet 521 and the second OIS coil portion 522 may be disposed on the OIS support portion 330, and the other of the second OIS magnet 521 and the second OIS coil portion 522 may be disposed on the housing 110. Hereinafter, an embodiment in which the second OIS magnet 521 is disposed on the OIS support portion 330 will be described.

[0171] The second OIS magnet 521 can be disposed on the OIS support portion 330. For example, the second OIS magnet 521 can be mounted on the other side surface of the OIS support portion 330 where the AF magnet 410 and the first OIS magnet 511 are not mounted.

[0172] The side surface on which the first OIS magnet 511 is mounted and the other side surface on which the second OIS magnet 521 is mounted can be perpendicular to each other.

[0173] The second OIS magnet 521 can be magnetized such that one of its surfaces has both an S pole and a N pole. As an example, an S pole, a neutral region, and an N pole can be sequentially arranged on one surface of the second OIS magnet 521 along the first axis (X-axis). The second OIS magnet 521 has a shape having length in the first axis (X-axis) direction.

[0174] Another surface of the second OIS magnet 521 can be magnetized to have a polarity opposite to that of one surface of the second OIS magnet 521.

[0175] The second OIS coil portion 522 is configured to face the second OIS magnet 521. For example, the second OIS coil portion 522 may be configured to face the second OIS magnet 521 in the direction of the second axis (Y-axis).

[0176] The second OIS coil portion 522 can be disposed on the fourth side surface 114 of the housing 110. An opening is provided in the fourth side surface 114 of the housing 110.

[0177] The second OIS coil portion 522 may include two coils spaced apart from each other, and the two coils of the second OIS coil portion 522 may each have a perforated annular shape.

[0178] In one embodiment, the second OIS coil portion 522 includes a third sub-coil 522a and a fourth sub-coil 522b. The third sub-coil 522a and the fourth sub-coil 522b are spaced apart from each other in the direction of the first axis (X-axis).

[0179] One of the two coils of the second OIS coil portion 522 can be configured to face the N pole on one surface of the second OIS magnet 521, and the other of the two coils of the second OIS coil portion 522 can be configured to face the S pole on one surface of the second OIS magnet 521.

[0180] For example, the polarity of the second OIS magnet 521 facing the third sub-coil 522a and the polarity of the second OIS magnet 521 facing the fourth sub-coil 522b can be different from each other.

[0181] Due to the polarity arrangement of the second OIS magnet 521 and the arrangement of the second OIS coil portion 522, magnetic field leakage can be prevented, and thus sufficient driving force can be generated even under low power conditions.

[0182] In this embodiment, the second OIS magnet 521 is configured as a single magnet, but the second OIS magnet 521 may also be configured to include multiple magnets. In this case, one surface of each of the multiple magnets may be configured to have a polarity.

[0183] The first OIS coil portion 512 and the second OIS coil portion 522 can be disposed on the substrate 140. For example, the first OIS coil portion 512 and the second OIS coil portion 522 can be disposed on the substrate 140 so as to face the first OIS magnet 511 and the second OIS magnet 521 respectively.

[0184] The substrate 140 is mounted on the side surface of the housing 110, and the first OIS coil portion 512 and the second OIS coil portion 522 can directly face the first OIS magnet 511 and the second OIS magnet 521 respectively through corresponding openings provided in the housing 110.

[0185] During image stabilization, the second OIS magnet 521 is a movable component mounted on the OIS carrier 330, and the second OIS coil portion 522 is a fixed component fixed to the housing 110.

[0186] The second OIS magnet 521 and the second OIS coil portion 522 can generate a driving force in the direction in which the second OIS magnet 521 and the second OIS coil portion 522 face each other (e.g., the direction of the second axis (Y axis)).

[0187] When power is applied to the second OIS coil portion 522, the lens module 200 and the OIS carrier portion 330 can move in the direction of the second axis (Y axis) by the electromagnetic force generated between the second OIS magnet 521 and the second OIS coil portion 522.

[0188] The first OIS magnet 511 and the second OIS magnet 521 are arranged perpendicularly to each other on a plane perpendicular to the optical axis (Z-axis), and the first OIS coil portion 512 and the second OIS coil portion 522 are also arranged perpendicularly to each other on a plane perpendicular to the optical axis (Z-axis).

[0189] The second guide unit G2 is disposed between the OIS support section 330 and the AF support section 300.

[0190] In this embodiment, the second guiding unit G2 may include a plurality of balls. When the OIS carrier 330 moves in a direction perpendicular to the optical axis (Z-axis), the plurality of balls may roll in the same direction.

[0191] The second guiding unit G2 includes three or more balls.

[0192] The second yoke 514 and the third yoke 524 are disposed on the AF support portion 300. The second yoke 514 and the third yoke 524 are configured to face the first OIS magnet 511 and the second OIS magnet 521 respectively in the optical axis (Z axis) direction.

[0193] Therefore, an attractive force is generated between the second yoke 514 and the first OIS magnet 511 in the optical axis (Z-axis) direction, and an attractive force is generated between the third yoke 524 and the second OIS magnet 521 in the optical axis (Z-axis) direction.

[0194] Therefore, the OIS support portion 330 and the AF support portion 300 can remain in contact with the second guide unit G2 by the attraction generated between the second yoke 514 and the first OIS magnet 511 and the attraction generated between the third yoke 524 and the second OIS magnet 521.

[0195] The second yoke 514 and the third yoke 524 can each be magnetic.

[0196] The second guide groove gr2 can be formed in either or both of the OIS support section 330 and the AF support section 300.

[0197] For example, the second guide groove gr2 can be formed in either or both of the surfaces of the OIS support portion 330 and the AF support portion 300 that face each other.

[0198] Multiple second guide slots gr2 are formed to correspond to multiple balls of the second guide unit G2.

[0199] The second guide unit G2 is housed in the second guide groove gr2 and inserted between the OIS support portion 330 and the AF support portion 300.

[0200] The size of the second guide groove gr2 is larger than the diameter of each of the plurality of balls in the second guide unit G2. For example, the planar shape of the second guide groove gr2 can be circular or polygonal.

[0201] In this embodiment, the camera module 1 can detect the position of the OIS carrier 330 in a direction perpendicular to the optical axis (Z-axis).

[0202] For this purpose, a second position sensor 513 and a third position sensor 523 are provided. The second position sensor 513 may be disposed on the substrate 140 facing the first OIS magnet 511, and the third position sensor 523 may be disposed on the substrate 140 facing the second OIS magnet 521. The second position sensor 513 and the third position sensor 523 may be Hall sensors.

[0203] Either or both of the second position sensor 513 and the third position sensor 523 may include two Hall sensors.

[0204] For example, the second position sensor 513 may include two Hall sensors configured to face the first OIS magnet 511. One of the two Hall sensors may be disposed in a hole in the first sub-coil 512a, and the other of the two Hall sensors may be disposed in a hole in the second sub-coil 512b.

[0205] The rotation of the OIS carrier 330 can be detected by two Hall sensors facing the first OIS magnet 511.

[0206] Since the first OIS coil portion 512 includes two coils facing the first OIS magnet 511, the first OIS coil portion 512 can be controlled to counteract the rotational force applied to the OIS bearing portion 330.

[0207] Reference Figure 7 One surface of the second OIS magnet 521 may have a first polarity 521a and a second polarity 521b spaced apart from each other in the direction of the first axis (X-axis). The first polarity 521a may be an N pole or a S pole, and the second polarity 521b may have a polarity opposite to that of the first polarity 521a.

[0208] The area of ​​the first polarity 521a may be different from the area of ​​the second polarity 521b. For example, the area of ​​the first polarity 521a may be larger than the area of ​​the second polarity 521b.

[0209] The lengths of the first polarity 521a and the second polarity 521b in the first axis (X-axis) direction can be different. For example, the length of the first polarity 521a in the first axis (X-axis) direction can be greater than the length of the second polarity 521b in the first axis (X-axis) direction.

[0210] The third sub-coil 522a of the second OIS coil portion 522 can be configured to face the first polarity 521a of the second OIS magnet 521, and the fourth sub-coil 522b of the second OIS coil portion 522 can be configured to face the second polarity 521b of the second OIS magnet 521.

[0211] The lengths of the third sub-coil 522a and the fourth sub-coil 522b in the first axis (X-axis) direction can be different. For example, the length of the third sub-coil 522a in the first axis (X-axis) direction can be greater than the length of the fourth sub-coil 522b in the first axis (X-axis) direction.

[0212] The third position sensor 523 can be located at a position spaced apart from the center of the third sub-coil 522a. For example, the third position sensor 523 can be located at a position spaced apart from the center of the third sub-coil 522a in the direction of the first axis (X-axis).

[0213] The position of the third position sensor 523 in the first axis (X-axis) direction can be set between the center of the third sub-coil 522a and the center of the fourth sub-coil 522b. That is, the third position sensor 523 can be set between the center of the third sub-coil 522a and the center of the fourth sub-coil 522b.

[0214] The third position sensor 523 can be configured to face one of the first polarities 521a and 521b of the second OIS magnet 521. For example, the third position sensor 523 can be configured to face the polarity with the larger length (or larger area) of the first polarity 521a and the second polarity 521b of the second OIS magnet 521.

[0215] In an embodiment, the third position sensor 523 may be configured to face the first polarity 521a of the second OIS magnet 521.

[0216] Furthermore, the third position sensor 523 can be configured to be spaced apart from the center C1 of the first polarity 521a of the second OIS magnet 521. Therefore, the third position sensor 523 can face the portion of the second OIS magnet 521 that is spaced apart from the center C1 of the first polarity 521a in the first axis (X-axis) direction.

[0217] In an embodiment, the center of the third position sensor 523 may be positioned spaced apart from the center C1 of the first polarity 521a of the second OIS magnet 521 in the direction of the first axis (X-axis). Here, the direction in which the center of the third position sensor 523 is spaced apart from the center C1 of the first polarity 521a of the second OIS magnet 521 in the direction of the first axis (X-axis) may be towards the second polarity 521b of the second OIS magnet 521.

[0218] For example, the third position sensor 523 may face the first polarity 521a of the second OIS magnet 521, and the center of the third position sensor 523 may be located between the center C1 of the first polarity 521a of the second OIS magnet 521 and the center C2 of the second polarity 521b of the second OIS magnet 521.

[0219] In this embodiment, the third position sensor 523 may be positioned to face the center C3 of the OIS support 330. For example, when viewed in the second axis (Y-axis) direction, the center C3 of a side surface of the OIS support 330 on which the second OIS magnet 521 is disposed may overlap with the third position sensor 523 in the first axis (X-axis) direction.

[0220] During image stabilization, the OIS carrier 330 can move along the first axis (X-axis) and the second axis (Y-axis) while being supported by the second guide unit G2.

[0221] In this situation, since the multiple balls of the second guide unit G2 can roll in various directions perpendicular to the optical axis (Z-axis), the OIS carrier 330 may rotate due to various unexpected factors (such as the deviation between the driving force of the first image stabilization actuator 510 and the driving force of the second image stabilization actuator 520).

[0222] In this case, an error may occur in the position of the OIS carrier 330 detected by the third position sensor 523.

[0223] In the camera module 1 according to an embodiment of the present disclosure, the length of the third sub-coil 522a is greater than the length of the fourth sub-coil 522b, and the third position sensor 523 is disposed at a position spaced apart from the center of the third sub-coil 522a.

[0224] Furthermore, the third position sensor 523 is configured to face a polarity with a greater length (e.g., the first polarity 521a) on one surface of the second OIS magnet 521, and the third position sensor 523 is configured to be biased from the center of the first polarity 521a toward the second polarity 521b.

[0225] Therefore, the third position sensor 523 can be positioned closer to the center of the OIS support 330 (preferably, the third position sensor 523 is positioned facing the center of the OIS support 330). Thus, even if unexpected rotation occurs in the OIS support 330, errors in the position of the OIS support 330 (position in the second axis (Y-axis) direction) detected by the third position sensor 523 can be prevented.

[0226] In other words, even when the OIS support 330 rotates, the distance between the second OIS magnet 521 and the third position sensor 523 can remain unchanged, or even if the distance between the second OIS magnet 521 and the third position sensor 523 changes, the change can be very small.

[0227] Therefore, the position of the OIS support 330 detected by the third position sensor 523 is not affected by the rotation of the OIS support 330.

[0230] For example, the first support guide g1 may have a cylindrical or semi-cylindrical shape extending in the direction of the optical axis (Z-axis).

[0231] The first axial support guide g1 can be fixed to one of the AF bearing part 300 and the housing 110.

[0236] Figure 20 It is along Figure 12 The cross-sectional view taken from line XX-XX'.

[0237] Reference Figures 12 to 15 According to another embodiment of the present disclosure, the camera module 2 includes an optical module and a housing 110.

[0238] The optical module can be understood to include either or both of the lens module 200 and the image sensor module 700. For example, in one embodiment, the optical module may refer to the lens module 200, while in another embodiment, the optical module may refer to the image sensor module 700.

[0239] The camera module 2 may also include an AF support unit 300. In this case, the lens barrel 220 can be connected to the AF support unit 300.

[0240] The AF support unit 300 can move relative to the housing 110 in the optical axis (Z-axis) direction. Since the lens barrel 220 is connected to the AF support unit 300, the lens barrel 220 can move together with the AF support unit 300 in the optical axis (Z-axis) direction.

[0241] In other words, the focus can be adjusted by changing the distance between the lens module 200 and the image sensor 710.

[0242] Camera module 2 may also include an OIS support unit 230. The OIS support unit 230 is disposed in housing 110 and is movable relative to housing 110 in a direction perpendicular to the optical axis (Z-axis). Lens module 200 and AF support unit 300 may be disposed in OIS support unit 230. Therefore, lens module 200, AF support unit 300 and OIS support unit 230 may move together in a direction perpendicular to the optical axis (Z-axis).

[0243] In other words, the lens module 200, the AF support unit 300, and the OIS support unit 230 can move in a direction perpendicular to the optical axis (Z-axis) to perform image stabilization during image capture.

[0244] The housing 110 may have a plate shape. However, this disclosure is not limited thereto, and the housing 110 may also be configured as shown in the reference. Figures 1 to 11 The described embodiment features a box shape with an open upper portion and an open lower portion.

[0245] The OIS support unit 230 can be disposed in the housing 110, and the lens module 200 and the AF support unit 300 can be accommodated in the OIS support unit 230.

[0246] The outer casing 120 is attached to the housing 110 to surround the outer surface of the housing 110 and to protect the internal components of the camera module 2.

[0247] Although not shown in the accompanying drawings, camera module 2 includes, as referenced... Figures 1 to 11 The image sensor module 700 in the described embodiment.

[0248] The image sensor module 700 is located below the housing 110.

[0249] Camera module 2 may also include a reference Figures 1 to 11 The stop member 130 of the described embodiment. The stop member 130 is coupled to the OIS support portion 230 so as to cover at least a portion of the upper surface of the AF support portion 300.

[0250] The camera module 2 may include a first actuator 400. The lens module 200 may be moved in the direction of the optical axis (Z-axis) via the first actuator 400.

[0251] For example, the first actuator 400 can generate a driving force in the optical axis (Z-axis) direction to move the AF support 300. Since the lens module 200 is connected to the AF support 300, the AF support 300 and the lens module 200 can move together in the optical axis (Z-axis) direction by the driving force of the first actuator 400.

[0252] The first actuator 400 includes an AF magnet 410 and an AF coil 430. The AF magnet 410 and the AF coil 430 can be arranged to face each other in a direction perpendicular to the optical axis (Z-axis). For example, the AF magnet 410 and the AF coil 430 can face each other in the direction of the first axis (X-axis).

[0253] One of the AF magnet 410 and the AF coil 430 may be disposed on the AF support portion 300, and the other of the AF magnet 410 and the AF coil 430 may be disposed on the housing 110. In the following description, an embodiment based on the AF magnet 410 being disposed on the AF support portion 300 will be given.

[0254] The AF magnet 410 is mounted on the AF support portion 300. As an example, the AF magnet 410 may be mounted on a side surface 301 of the AF support portion 300.

[0255] The AF magnet 410 can be magnetized such that one surface of the AF magnet 410 (e.g., the surface facing the AF coil 430) has both a N pole and a S pole. As an example, the N pole, the neutral region, and the S pole can be sequentially arranged on one surface of the AF magnet 410 facing the AF coil 430 in the optical axis (Z-axis) direction.

[0256] In this specification, the first polarity may refer to the N pole or the S pole, and the second polarity may refer to the polarity opposite to the first polarity.

[0257] The AF coil 430 is configured to face the AF magnet 410. For example, the AF coil 430 may be configured to face the AF magnet 410 in a direction perpendicular to the optical axis (Z-axis).

[0258] The AF coil 430 is disposed on the connecting substrate 600, and a portion of the connecting substrate 600 is mounted on the OIS carrier 230, such that the AF magnet 410 and the AF coil 430 face each other in a direction perpendicular to the optical axis (Z-axis).

[0259] During focus adjustment, the AF magnet 410 is a movable member mounted on the AF support 300 and moving together with the AF support 300 in the optical axis (Z-axis) direction, and the AF coil 430 is a fixed member fixed to the connecting substrate 600. For reference, the AF coil 430 can be a movable member during image stabilization.

[0260] When power is applied to the AF coil 430, the AF support 300 can move in the direction of the optical axis (Z axis) by the electromagnetic force generated between the AF magnet 410 and the AF coil 430.

[0261] Since the lens module 200 is connected to the AF support 300, the lens module 200 also moves in the optical axis (Z-axis) direction by moving the AF support 300.

[0262] The first guide unit G1 is disposed between the AF support section 300 and the OIS support section 230. The first guide unit G1 can guide the movement of the AF support section 300.

[0263] The first guide unit G1 includes a first support guide g1 and a second support guide g2 spaced apart from each other in a direction perpendicular to the optical axis (Z-axis).

[0264] In this embodiment, the first guiding unit G1 may include a plurality of balls. When the AF bearing portion 300 moves in the optical axis (Z-axis) direction, the plurality of balls may roll in the optical axis (Z-axis) direction.

[0265] For example, the first support guide g1 may include a plurality of balls.

[0266] In another embodiment, the first support guide g1 may have an axial shape having length in the optical axis (Z-axis) direction (see [reference]). Figure 11 For example, the first support guide g1 may have a cylindrical or semi-cylindrical shape extending in the direction of the optical axis (Z-axis).

[0267] The shaft-shaped first support guide g1 can be fixed to the AF bearing part 300 or the OIS bearing part 230.

[0268] Furthermore, the second support guide g2 may include a protrusion projecting from either or both of the AF support portion 300 and the OIS support portion 230. The surface of the protrusion may have a curved surface. For example, the protrusion may have a hemispherical shape. Alternatively, the second support guide g2 may be configured to include one or more spheres.

[0269] The first support guide g1 can be used as a main guide for the lens module 200 to move in the direction of the optical axis (Z axis).

[0270] The second support guide g2 can be used as an auxiliary guide to support the movement of the lens module 200 in the optical axis (Z-axis) direction.

[0271] The second support guide g2 can be positioned between the opposite ends of the first support guide g1 in the optical axis (Z-axis) direction.

[0272] The first yoke 470 is disposed on the OIS support portion 230. The first yoke 470 may be disposed at a position spaced apart from the AF magnet 410 in the first axis (X-axis) direction. The first yoke 470 may be disposed on the connecting substrate 600.

[0273] The AF magnet 410 and the first yoke 470 can generate an attractive force therebetween. For example, the first yoke 470 can be made of a magnetic material. The attractive force acts between the AF magnet 410 and the first yoke 470 in a direction perpendicular to the optical axis (Z-axis) (e.g., the first axis (X-axis) direction).

[0274] The first guide groove gr1 can be formed in either or both of the AF support portion 300 and the OIS support portion 230.

[0275] For example, the first guide groove gr1 can be formed in either the surface of the AF support portion 300 or the surface of the OIS support portion 230, which are facing each other.

[0276] The first guide groove gr1 extends in the direction of the optical axis (Z-axis). The first support guide g1 is disposed in the first guide groove gr1.

[0277] The first support guide g1 and the second support guide g2 are spaced apart from each other in a direction perpendicular to the optical axis (Z-axis) (e.g., the first axis (X-axis) direction). The first support guide g1 includes a plurality of balls disposed in the optical axis (Z-axis) direction. The second support guide g2 includes a smaller number of protrusions (or balls) than the number of balls included in the first support guide g1.

[0278] For example, the first support guide g1 includes two or more balls arranged in the direction of the optical axis (Z-axis), and the second support guide g2 includes fewer protrusions (or balls) than the number of balls included in the first support guide g1.

[0279] The first support guide g1 may be disposed in the corner region of the camera module 2. The corner region may refer to the portion where two surfaces perpendicular to each other intersect. However, in this specification, the corner region is not limited to a point geometrically defined as a corner, but may refer to a region within a predetermined range including the portion (or surrounding portion) adjacent to the corner.

[0280] According to embodiments of this disclosure, when viewed along the optical axis (Z-axis), the camera module 2 may have a quadrilateral shape including four corner regions. A first support guide g1 may be disposed in one of the four corner regions.

[0281] Reference Figure 16The AF support portion 300 includes one side surface 301 and another side surface 302. The side surface 301 and the other side surface 302 can be surfaces perpendicular to each other.

[0282] The AF support portion 300 includes a first corner portion 320 located at the intersection of one side surface 301 and another side surface 302, and a first guide groove gr1 provided therein may be formed in the first corner portion 320.

[0283] The AF support portion 300 may have a shape in which the protrusion extends along the optical axis (Z-axis) below the bottom surface of the AF support portion 300 at the first corner portion 320. That is, the first corner portion 320 of the AF support portion 300 has a longer length in the optical axis (Z-axis) direction than other portions of the AF support portion 300. In the following text, the protrusion is defined as the extension portion 310.

[0284] Reference Figure 15 and Figure 20 The receiving portion 116 can be formed in the bottom surface of the housing 110. The receiving portion 116 can be disposed at a position facing the extension portion 310 in the optical axis (Z-axis) direction.

[0285] The receiving portion 116 may have a groove shape recessed in the bottom surface of the housing 110 or a hole shape passing through the bottom surface of the housing 110.

[0286] The support portion 116a may be formed in the bottom surface of the housing 110 adjacent to the receiving portion 116 to prevent the first support guide g1 from separating from the first guide groove gr1. The height of the support portion 116a in the optical axis (Z-axis) direction may be less than the height of the bottom surface of the housing 110 in the optical axis (Z-axis) direction.

[0287] A protrusion 121 can be formed in the housing 120, protruding toward the first support guide g1. The protrusion 121 can be a portion that protrudes downward from one surface of the housing 120 in the optical axis (Z-axis) direction. The protrusion 121 can face the first support guide g1 in the optical axis (Z-axis) direction to prevent the first support guide g1 from separating from the first guide groove gr1.

[0288] A portion of the first guide groove gr1 can be formed in the extension portion 310. Therefore, the first guide groove gr1 can have sufficient length in the optical axis (Z-axis) direction, and the two balls included in the first support guide g1 can be stacked and disposed in the first guide groove gr1 in the optical axis (Z-axis) direction.

[0289] In an embodiment, the second support guide g2 may refer to a protrusion that protrudes from the inner surface of the OIS support portion 230 toward the other side surface 302 of the AF support portion 300.

[0290] The second support guide g2 can contact the other side surface 302 of the AF bearing part 300.

[0291] In this embodiment, the second support guide g2 may have a length in the direction of the optical axis (Z-axis). For example, when cut in a direction perpendicular to the optical axis (Z-axis), the second support guide g2 may be configured as an axis with a hemispherical cross-section.

[0292] Alternatively, in another embodiment, the second support guide g2 is a plurality of protrusions disposed in the direction of the optical axis (Z-axis).

[0293] Camera module 2 may also include a first magnetic body 411 and a second magnetic body 472.

[0294] In one embodiment, one of the first magnetic body 411 and the second magnetic body 472 may be a magnet, and the other of the first magnetic body 411 and the second magnetic body 472 may be a magnetic yoke. In another embodiment, both the first magnetic body 411 and the second magnetic body 472 may be magnets.

[0295] In the following description, an embodiment in which the first magnetic body 411 mounted on the other side surface 302 of the AF support 300 is a magnet and the second magnetic body 472 is a yoke will be described.

[0296] The first magnetic body 411 can be disposed on another side surface 302 of the AF support part 300.

[0297] The second magnetic body 472 can be configured to face the first magnetic body 411 in a direction perpendicular to the optical axis (Z-axis) (e.g., in the second axis (Y-axis) direction). In an embodiment, the second magnetic body 472 can be disposed on the OIS support portion 230.

[0298] The attraction can act between the first magnetic body 411 and the second magnetic body 472.

[0299] Reference Figure 19 The first attractive force Fa acts between the AF magnet 410 and the first yoke 470 in the first axis (X-axis) direction, and the second attractive force Fb acts between the first magnet 411 and the second magnet 472 in the second axis (Y-axis) direction.

[0300] Therefore, the direction of the first attractive force Fa acting between the AF magnet 410 and the first yoke 470 and the direction of the second attractive force Fb acting between the first magnetic body 411 and the second magnetic body 472 can be perpendicular to each other.

[0301] like Figure 19 As shown, the resultant force Fc of the first attraction Fa and the second attraction Fb acts in the diagonal direction, and the direction of the resultant force Fc can be toward the first support guide g1.

[0302] Therefore, the first support guide g1 can stably support the AF bearing part 300.

[0303] Figure 21 It is shown in Figure 12 A diagram of the rotational torque generated in the camera module.

[0304] The AF magnet 410 and the first magnet 411 can be positioned at different distances from the first support guide g1, and therefore, uneven rotational torque can act on the first support guide g1.

[0305] In this embodiment, the distance between the AF magnet 410 and the first support guide g1 can be less than the distance between the first magnet 411 and the first support guide g1. That is, the AF magnet 410 can be positioned closer to the first support guide g1, which serves as the main guide, than the first magnet 411.

[0306] Reference Figure 21 The first distance d1 between the center of the AF magnet 410 and the center of the first support guide g1 can be shorter than the second distance d2 between the center of the first magnet 411 and the center of the first support guide g1. This arrangement assumes that the dimensions of the AF magnet 410 and the first magnet 411 are the same, and that the dimensions of the first yoke 470 and the second magnet 472 are the same.

[0307] Since the first attractive force Fa and the second attractive force Fb act at positions spaced apart from the first support guide g1, a rotational torque can be applied to the first support guide g1 through the first attractive force Fa and the second attractive force Fb. In this case, assuming that the magnitudes of the first attractive force Fa and the second attractive force Fb are approximately the same, when the second distance d2 is greater than the first distance d1, the rotational torque generated by the second attractive force Fb can act more strongly on the first support guide g1 than the rotational torque generated by the first attractive force Fa.

[0308] Therefore, the AF support 300 and the lens module 200 can be as follows: Figure 21 Rotate clockwise as shown.

[0309] Since the AF carrier 300 is supported by the second support guide g2, the AF carrier 300 and the lens module 200 can ultimately move in the optical axis (Z-axis) direction while being supported by the first support guide g1 and the second support guide g2.

[0310] In another embodiment, the AF magnet 410 and the first magnetic body 411 can be configured such that the first distance d1 between the center of the AF magnet 410 and the center of the first support guide g1 can be the same as the second distance d2 between the center of the first magnetic body 411 and the center of the first support guide g1, and by making the dimensions of the AF magnet 410 and the first magnetic body 411 and / or the dimensions of the first yoke 470 and the second magnetic body 472 different from each other, an uneven rotational torque can be caused.

[0311] Furthermore, the position of the second support guide g2 can be changed according to the rotation direction of the AF support 300 and the lens module 200, so that as the AF support 300 and the lens module 200 rotate, the AF support 300 presses against the second support guide g2.

[0312] Figure 22 yes Figure 15 Exploded perspective view of the housing, OIS support, and second actuator. Figure 23 yes Figure 15 Exploded perspective view of the housing, OIS support, and second actuator.

[0313] Figure 24 and Figure 25 yes Figure 15 A plan view of the first actuator and the first image stabilization actuator.

[0314] In this embodiment, the camera module 2 can detect the position of the AF support 300 in the direction of the optical axis (Z axis).

[0315] For this purpose, a first position sensor 450 is provided. The first position sensor 450 is disposed on the connecting substrate 600 facing the AF magnet 410. The first position sensor 450 may be a Hall sensor.

[0316] Reference Figure 22 The camera module 2 can perform image stabilization during image capture by moving the lens module 200 in a direction perpendicular to the optical axis (Z-axis). For this purpose, the camera module 2 includes a second actuator 500 that moves the lens module 200 in a direction perpendicular to the optical axis (Z-axis).

[0317] Driven by the second actuator 500, the lens module 200, the AF support 300, and the OIS support 230 can move together in a direction perpendicular to the optical axis (Z-axis).

[0318] For example, the lens module 200, the AF support 300, and the OIS support 230 can move together in the first axis (X-axis) direction and the second axis (Y-axis) direction.

[0319] The second actuator 500 includes a first image stabilization actuator 510 and a second image stabilization actuator 520. The first image stabilization actuator 510 can generate a driving force in the direction of a first axis (X-axis), and the second image stabilization actuator 520 can generate a driving force in the direction of a second axis (Y-axis).

[0320] The first image stabilization actuator 510 includes a first OIS magnet 511 and a first OIS coil portion 512. The first OIS magnet 511 and the first OIS coil portion 512 may be configured to face each other in the optical axis (Z-axis) direction.

[0321] One of the first OIS magnet 511 and the first OIS coil portion 512 may be disposed on the OIS support portion 230, and the other of the first OIS magnet 511 and the first OIS coil portion 512 may be disposed on the housing 110. Hereinafter, an embodiment based on the first OIS magnet 511 being disposed on the OIS support portion 230 will be described.

[0322] The first OIS magnet 511 can be provided on the OIS support portion 230. For example, the first OIS magnet 511 can be mounted on the lower surface of the OIS support portion 230.

[0323] The first OIS magnet 511 can be magnetized such that one of its surfaces has both an N pole and a S pole. As an example, the N pole, the neutral region, and the S pole can be sequentially arranged on one surface of the first OIS magnet 511 along a first axis (X-axis). The first OIS magnet 511 has a shape having length in the second axis (Y-axis) direction.

[0324] Another surface of the first OIS magnet 511 can be magnetized to have a polarity opposite to that of one surface of the first OIS magnet 511.

[0325] The first OIS magnet 511 may include two magnets spaced apart from each other in the direction of the second axis (Y axis).

[0326] The first OIS coil portion 512 can be configured to face the first OIS magnet 511. For example, the first OIS coil portion 512 can be configured to face the first OIS magnet 511 in the optical axis (Z-axis) direction.

[0327] The first OIS coil portion 512 may include two coils spaced apart from each other, and the two coils of the first OIS coil portion 512 may each have a perforated annular shape.

[0328] In an embodiment, the first OIS coil portion 512 may include a first sub-coil 512a and a second sub-coil 512b. The first sub-coil 512a and the second sub-coil 512b may be spaced apart from each other in the direction of the second axis (Y-axis).

[0329] Therefore, a separation space 512c can be formed between the first sub-coil 512a and the second sub-coil 512b in the direction of the second axis (Y-axis) (see...). Figure 24 and Figure 25 ).

[0330] One of the two coils of the first OIS coil portion 512 can be configured to face one of the two magnets of the first OIS magnet 511, and the other of the two coils of the first OIS coil portion 512 can be configured to face the other of the two magnets of the first OIS magnet 511.

[0331] During image stabilization, the first OIS magnet 511 is a movable component mounted on the OIS carrier 230, and the first OIS coil portion 512 is a fixed component fixed to the housing 110.

[0332] The first OIS magnet 511 and the first OIS coil portion 512 can generate a driving force in a direction perpendicular to the direction in which the first OIS magnet 511 and the first OIS coil portion 512 face each other (e.g., the direction of the first axis (X-axis)).

[0333] When power is applied to the first OIS coil portion 512, the OIS carrier portion 230, the AF carrier portion 300, and the lens module 200 can move in the direction of the first axis (X-axis) by the electromagnetic force generated between the first OIS magnet 511 and the first OIS coil portion 512.

[0334] When viewed along the optical axis (Z-axis), the first OIS magnet 511 can be positioned at a location spaced apart from the AF magnet 410 along the first axis (X-axis).

[0335] Furthermore, when viewed along the optical axis (Z-axis), the two coils of the first OIS coil portion 512 can be positioned at a distance from the AF magnet 410 along the first axis (X-axis). For example, the first sub-coil 512a and the second sub-coil 512b can be positioned at a distance from the AF magnet 410 along the first axis (X-axis).

[0336] Here, when viewed in the direction of the optical axis (Z-axis), the center of the AF magnet 410 in the direction of the second axis (Y-axis) can be spaced apart from the separation space 512c between the two coils of the first OIS coil portion 512 in the direction of the second axis (Y-axis).

[0337] The distance between the center of the AF magnet 410 and the first support guide g1 in the second axis (Y axis) direction can be less than the distance between the separation space 512c between the first sub-coil 512a and the second sub-coil 512b and the first support guide g1 in the second axis (Y axis) direction.

[0338] Since the first OIS magnet 511 includes two magnets spaced apart from each other in the direction of the second axis (Y axis), a separation space can also be formed between the two magnets.

[0339] The relationship between the position of the center of the AF magnet 410 in the second axis (Y-axis) and the position of the separation space between the two magnets in the second axis (Y-axis) is the same as that described above for the separation space 512c between the first sub-coil 512a and the second sub-coil 512b.

[0340] In other words, the separation space between the center of the AF magnet 410 and the two magnets of the first OIS magnet 511 can be spaced apart in the direction of the second axis (Y axis).

[0341] The distance between the center of the AF magnet 410 and the first support guide g1 in the second axis (Y axis) direction can be less than the distance between the separation space between the two magnets of the first OIS magnet 511 and the distance between the first support guide g1 in the second axis (Y axis) direction.

[0342] In other words, the center of the AF magnet 410 can be set closer to the first support guide g1 than the separation space between the two magnets of the first OIS magnet 511.

[0343] The distance between the center of the AF magnet 410 and a side surface of the housing 110 in the second axis (Y-axis) direction may be different from the distance between the separation space 512c between the two coils of the first OIS coil portion 512 and a side surface of the housing 110 in the second axis (Y-axis) direction.

[0344] For example, the distance between the center of the AF magnet 410 and a side surface of the housing 110 in the second axis (Y-axis) direction can be less than the distance between the partition space 512c between the two coils of the first OIS coil portion 512 and a side surface of the housing 110 in the second axis (Y-axis) direction.

[0345] Here, a side surface of housing 110 may refer to the surface of housing 110 that is closest to AF magnet 410 among the side surfaces of housing 110 that are perpendicular to AF magnet 410.

[0346] Alternatively, one side surface of housing 110 may refer to the side surface of housing 110 opposite to the side on which the second image stabilization actuator 520 is disposed.

[0347] The ratio of the length of the first OIS magnet 511 in the second axis (Y-axis) direction to the length of the AF magnet 410 in the second axis (Y-axis) direction is greater than or equal to 0.5 and less than or equal to 1.

[0348] When viewed along the first axis (X-axis), the center of the AF magnet 410 and the center of the lens barrel 220 can be spaced apart from each other along the second axis (Y-axis).

[0349] When viewed along the optical axis (Z-axis), the center of the AF magnet 410 can be positioned at a location spaced apart from the center of the imaging surface of the image sensor 710 along the first axis (X-axis) and the second axis (Y-axis).

[0350] The second image stabilization actuator 520 includes a second OIS magnet 521 and a second OIS coil portion 522. The second OIS magnet 521 and the second OIS coil portion 522 may be arranged to face each other in the optical axis (Z-axis) direction.

[0351] One of the second OIS magnet 521 and the second OIS coil portion 522 may be disposed on the OIS support portion 230, and the other of the second OIS magnet 521 and the second OIS coil portion 522 may be disposed on the housing 110. Hereinafter, an embodiment in which the second OIS magnet 521 is disposed on the OIS support portion 230 will be described.

[0352] The second OIS magnet 521 can be provided on the OIS support portion 230. For example, the second OIS magnet 521 can be mounted on the lower surface of the OIS support portion 230.

[0353] The second OIS magnet 521 can be magnetized such that one of its surfaces has both an S pole and a N pole. As an example, an S pole, a neutral region, and an N pole can be sequentially arranged on one surface of the second OIS magnet 521 along the second axis (Y-axis). The second OIS magnet 521 has a shape having length in the first axis (X-axis) direction.

[0354] Another surface of the second OIS magnet 521 can be magnetized to have a polarity opposite to that of one surface of the second OIS magnet 521.

[0355] The second OIS coil portion 522 is configured to face the second OIS magnet 521. For example, the second OIS coil portion 522 may be configured to face the second OIS magnet 521 in the optical axis (Z-axis) direction.

[0356] The coil of the second OIS coil section 522 can have a ring shape with holes.

[0357] The first OIS coil portion 512 and the second OIS coil portion 522 may be disposed on a substrate (not shown). For example, the first OIS coil portion 512 and the second OIS coil portion 522 may be disposed on a substrate (not shown) so as to face the first OIS magnet 511 and the second OIS magnet 521, respectively.

[0358] The substrate (not shown) can be mounted on the lower surface of the housing 110, and the first OIS coil portion 512 and the second OIS coil portion 522 can directly face the first OIS magnet 511 and the second OIS magnet 521 respectively through the openings provided in the housing 110.

[0359] Alternatively, the first OIS coil portion 512 and the second OIS coil portion 522 can be disposed on a printed circuit board 720 on which the image sensor 710 is mounted (see [link]). Figure 2 ).

[0360] During image stabilization, the second OIS magnet 521 is a movable component mounted on the OIS carrier 230, and the second OIS coil portion 522 is a fixed component fixed to the housing 110.

[0361] The second OIS magnet 521 and the second OIS coil portion 522 can generate a driving force in a direction perpendicular to the direction in which the second OIS magnet 521 and the second OIS coil portion 522 face each other (e.g., the direction of the second axis (Y-axis)).

[0362] When power is applied to the second OIS coil portion 522, the lens module 200 and the OIS carrier portion 230 can move in the direction of the second axis (Y axis) by the electromagnetic force generated between the second OIS magnet 521 and the second OIS coil portion 522.

[0363] The first OIS magnet 511 and the second OIS magnet 521 are arranged perpendicularly to each other on a plane perpendicular to the optical axis (Z-axis), and the first OIS coil portion 512 and the second OIS coil portion 522 are also arranged perpendicularly to each other on a plane perpendicular to the optical axis (Z-axis).

[0364] The second guide unit G2 is disposed between the OIS support section 230 and the housing 110.

[0365] In this embodiment, the second guiding unit G2 may include a plurality of balls. When the OIS carrier 230 moves in a direction perpendicular to the optical axis (Z-axis), the plurality of balls may roll in the direction perpendicular to the optical axis (Z-axis).

[0366] The second guiding unit G2 includes three or more balls.

[0367] The second yoke 514 and the third yoke 524 can be disposed on the housing 110. The second yoke 514 is disposed facing the first OIS magnet 511 in the optical axis (Z-axis) direction, and the third yoke 524 is disposed facing the second OIS magnet 521 in the optical axis (Z-axis) direction.

[0368] Therefore, an attractive force is generated between the second yoke 514 and the first OIS magnet 511 in the optical axis (Z-axis) direction, and an attractive force is generated between the third yoke 524 and the second OIS magnet 521 in the optical axis (Z-axis) direction.

[0369] Therefore, the OIS carrier 230 and housing 110 can be kept in contact with the second guide unit G2 by these attractive forces.

[0370] The second yoke 514 and the third yoke 524 can each be magnetic.

[0371] The second guide groove gr2 can be formed in either or both of the OIS support portion 230 and the housing 110.

[0372] For example, the second guide groove gr2 can be formed in the surfaces of the OIS support portion 230 and the housing 110, which face each other.

[0373] Multiple second guide slots gr2 are formed to correspond to multiple balls of the second guide unit G2.

[0374] The second guide unit G2 is housed in the second guide groove gr2 and inserted between the OIS support portion 230 and the housing 110.

[0375] The size of the second guide groove gr2 is larger than the diameter of each of the plurality of balls in the second guide unit G2. For example, the planar shape of the second guide groove gr2 can be circular or polygonal.

[0376] In this embodiment, the camera module 2 can detect the position of the OIS carrier 230 in a direction perpendicular to the optical axis (Z-axis).

[0377] For this purpose, a second position sensor 513 and a third position sensor 523 are provided. The second position sensor 513 may be disposed on a substrate (not shown) facing the first OIS magnet 511, and the third position sensor 523 may be disposed on a substrate (not shown) facing the second OIS magnet 521. The second position sensor 513 and the third position sensor 523 may be Hall sensors.

[0378] Alternatively, the second position sensor 513 and the third position sensor 523 can be disposed on a printed circuit board 720 on which the image sensor 710 is mounted (see [reference]). Figure 2 ).

[0379] Either or both of the second position sensor 513 and the third position sensor 523 may include two Hall sensors.

[0380] For example, the second position sensor 513 may include two Hall sensors configured to face the first OIS magnet 511. One of the two Hall sensors may be disposed in a hole in the first sub-coil 512a, and the other of the two Hall sensors may be disposed in a hole in the second sub-coil 512b.

[0381] By using two Hall sensors facing the first OIS magnet 511, it is possible to detect whether the OIS carrier 230 is rotating.

[0382] Since the first OIS coil portion 512 includes two coils facing the first OIS magnet 511, the first OIS coil portion 512 can be controlled to counteract the rotational force applied to the OIS bearing portion 230.

[0383] Figure 26 yes Figure 15 A three-dimensional view of the connecting substrate, and Figure 27 yes Figure 15 A plan view of the connecting substrate in the connected state.

[0384] Reference Figure 26 and Figure 27 The AF coil 430 facing the AF magnet 410 can be provided on the OIS support portion 230, which is a movable member. Therefore, the connecting plate 600 on which the AF coil 430 is provided can be configured to support the movement of the OIS support portion 230.

[0385] At least a portion of the connecting substrate 600 may be made of a flexible material. The flexible material may be adapted to support the movement of the OIS support portion 230.

[0386] The connecting substrate 600 can have a shape that can be bent multiple times, and can be disposed in the space between the OIS support portion 230 and the housing 120.

[0387] The connecting substrate 600 may include four parts disposed at different locations between the OIS support portion 230 and the housing 120, and may be bent at the boundaries of the four parts.

[0388] The four parts may include a first part 610, a second part 620, a third part 630, and a fourth part 640. When the connecting substrate 600 is unfolded, the first part 610, the second part 620, the third part 630, and the fourth part 640 may be arranged sequentially along the longitudinal direction of the connecting substrate 600.

[0389] The first part 610 may be disposed on one side surface 301 of the OIS support portion 230 and the AF support portion 300 (see...). Figure 16 and Figure 17 On one of the side surfaces facing.

[0390] AF coil 430 and first position sensor 450 (see Figure 15 and Figure 18 The AF coil 430 and the first position sensor 450 can be disposed on one surface of the first part 610. The AF coil 430 and the first position sensor 450 can face the AF magnet 410 through the opening in the OIS carrier 230.

[0391] The first yoke 470 may be disposed on the surface of the first portion 610 opposite to a surface, and the first yoke 470 may face the AF magnet 410, and the AF coil 430 and the first position sensor 450 are inserted between the first yoke 470 and the AF magnet 410.

[0392] Part 610 can be made of a rigid material to ensure rigidity.

[0393] The second part 620 may be a portion that bends and extends from the first part 610 so as to be set substantially parallel to the first part 610.

[0394] The second portion 620 may be spaced apart from one side surface of the OIS support portion 230 in the first axis (X-axis) direction, and the first portion 610 is inserted between the second portion 620 and one side surface of the OIS support portion 230. Furthermore, the second portion 620 may be spaced apart from the first portion 610 in the first axis (X-axis) direction, and may also be spaced apart from the first yoke 470 in the first axis (X-axis) direction. The second portion 620 may be spaced apart from the housing 120 in the first axis (X-axis) direction on the opposite side of the first portion 610.

[0395] The third part 630 may be a portion that bends and extends from the second part 620 so as to be substantially perpendicular to the first part 610 and the second part 620.

[0396] The third part 630 can be connected in the second axis (Y-axis) direction to the other side surface 302 of the OIS support 230 and the AF support 300 (see...). Figure 16 and 17 The third part 630 is spaced apart from the other side surface facing it. In addition, the third part 630 may also be spaced apart from the second magnetic body 472 disposed on the other side surface of the OIS support part 230 in the direction of the second axis (Y axis).

[0397] The fourth part 640 may be a portion that bends and extends from the third part 630 so as to be set substantially parallel to the third part 630.

[0398] The fourth portion 640 may be spaced apart from the other side surface of the OIS support portion 230 in the second axis (Y-axis) direction, and the third portion 630 is inserted between the fourth portion 640 and the other side surface of the OIS support portion 230, and the fourth portion 640 may also be spaced apart from the third portion 630 in the second axis (Y-axis) direction. At least a portion of the fourth portion 640 may be spaced apart from the housing 120 in the second axis (Y-axis) direction on the side opposite to the third portion 630.

[0399] Although not shown in the accompanying drawings, a connection portion (not shown) configured to receive electrical signals from the outside may be formed on the fourth part 640.

[0400] Reference Figure 27 One end 641 of the fourth part 640 can be connected to the housing 120. That is, the connecting base plate 600 can be fixed at one end in its longitudinal direction to the housing 120, which serves as a fixing member, while elastically supporting the movement of the OIS support part 230.

[0401] In another embodiment, one end 641 of the fourth portion 640 may be connected to the housing 110, which serves as a fixing member.

[0402] As described above, since the first portion 610 of the connecting substrate 600 is disposed on the OIS support portion 230, the connecting substrate 600 and the OIS support portion 230 can move relative to the housing 110 in a direction perpendicular to the optical axis (Z-axis). In the connecting substrate 600, the end 641 of the fourth portion 640 that is connected to the housing 120 (or housing 110) can be a fixed portion, and the remaining portion can be a movable portion.

[0403] The connecting substrate 600 can be configured to be spaced apart from the bottom surface of the housing 110 in the optical axis (Z-axis) direction. With this configuration, interference with the housing 110 can be prevented when the connecting substrate 600 moves together with the OIS support 230.

[0404] The connecting substrate 600 can extend in a curved manner between the OIS support portion 230 and the housing 120, and can be configured to be spaced apart from the housing 120 in order to support the movement of the OIS support portion 230.

[0405] Reference Figure 27 A portion of the fourth portion 640 of the connecting substrate 600 may be spaced apart from the housing 120 by a distance d3 in the second axis (Y-axis) direction, and the second portion 620 may be spaced apart from the housing 120 by a distance d4 in the first axis (X-axis) direction.

[0406] Therefore, when the OIS carrier 230 moves via the second actuator 500, the tension applied to the connecting substrate 600 can be reduced.

[0407] Figure 28 It is shown Figure 15 A plan view showing the positions of the first and second guide units.

[0408] Reference Figure 28 By setting a first guide unit G1 (a first support guide g1 and a second support guide g2) and a second guide unit G2 so that the first guide unit G1 and the second guide unit G2 do not overlap each other in the optical axis (Z-axis) direction, the thickness of the camera module 2 can be minimized. The first guide unit G1 guides the movement of the lens module 200 in the optical axis (Z-axis) direction, and the second guide unit G2 guides the movement of the OIS carrier 230 in the direction perpendicular to the optical axis (Z-axis).

[0409] The first support guide g1 of the first guide unit G1 can be disposed in a corner region of the camera module 2, and the second guide unit G2 can be disposed in one of the remaining corner regions of the camera module 2 other than the corner region.
