Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2021-0175103, filed on December 8, 2021, with the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

[0003] The following description pertains to the camera module. Background Technology

[0004] Cameras have been largely adopted in portable electronic devices such as smartphones, tablet PCs, and laptop PCs, and cameras in mobile devices have added features such as autofocus (AF), optical image stabilization (OIS), and zoom.

[0005] However, in order to achieve various functions, the structure of camera modules has become more complex and the size of camera modules has increased, resulting in an increase in the size of portable electronic devices in which camera modules are installed.

[0006] Furthermore, when directly moving a lens or image sensor for optical image stabilization, not only the weight of the lens or image sensor itself needs to be considered, but also the weight of other components to which the lens or image sensor is attached. Consequently, a predetermined level or more driving force is required, leading to increased power consumption.

[0007] Furthermore, to achieve both autofocus (AF) and zoom functions, it is necessary to ensure that the predetermined length or greater allows multiple lens barrels to move a long distance along the optical axis, and it is also necessary to prevent misalignment of the optical axes between the multiple lens barrels. However, it is difficult to achieve such a structure in a very small and compact camera design. Summary of the Invention

The drawings may not be drawn to scale, and for clarity, illustration, and convenience, the relative dimensions, scale, and descriptions of elements in the drawings may be exaggerated. Detailed Implementation

[0059] The following detailed description is provided to aid the reader in fully understanding the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents to the methods, apparatus, and / or systems described herein will be apparent to those skilled in the art. The sequences of operations described herein are merely illustrative, except for those that must occur in a specific order, and are not limited to those set forth herein; rather, changes that will be apparent to those skilled in the art are permissible. Furthermore, for clarity and conciseness, descriptions of functions and structures well-known to those skilled in the art may be omitted.

[0060] The features described herein may be implemented in various forms and should not be construed as limited to the examples described herein. Rather, the embodiments described herein have been provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art.

[0061] In this document, it should be noted that the term “may” is used in relation to examples or implementations. For example, when referring to what an example or implementation may include or implement, it means that there exists at least one example or implementation that includes or implements such a feature, but all examples and implementations are not limited thereto.

[0062] Throughout the specification, when an element such as a layer, region, or substrate is described as being “on,” “connected to,” or “attached to” another element, it may be directly “on,” directly “connected to,” or directly “attached to” that other element, or there may be one or more other elements in between. Conversely, when an element is described as being “directly” “on,” directly “connected to,” or directly “attached to” another element, there cannot be other elements in between.

[0063] As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more.

[0064] 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 the examples may also be referred to as a second component, second part, second region, second layer, or second section.

[0065] 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 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” that other element or “below” it relative to other elements. Thus, depending on the spatial orientation of the device, the term “above” covers both “above” and “below” orientations. 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.

[0066] 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” describe the presence of features, numbers, operations, components, elements, and / or combinations thereof stated, but do not exclude the presence or addition of one or more other features, numbers, operations, components, elements, and / or combinations thereof.

[0067] The shapes shown in the accompanying drawings may vary due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the accompanying drawings, but include shape variations that occur during manufacturing.

[0068] It will be apparent upon understanding the disclosure of this application that the features of the examples described herein can be combined in various ways. Furthermore, although the examples described herein have multiple configurations, it will be apparent upon understanding the disclosure of this application that other configurations are also possible.

[0069] For purposes of clarity, illustration and convenience, the accompanying drawings may not be drawn to scale, and the relative dimensions, scale and depiction of elements in the drawings may be exaggerated.

[0070] The example will be described in detail below with reference to the accompanying drawings.

[0071] Figure 1 It is a 3D diagram of a portable electronic device based on an example.

[0072] refer to Figure 1 The portable electronic device 1 may be a portable electronic device such as a mobile communication terminal, a smartphone, or a tablet personal computer (PC) in which multiple camera modules 500 and 1000 are installed.

[0073] In this example, multiple camera modules 500 and 1000 can be installed in the portable electronic device 1. Although in Figure 1 The diagram shows multiple camera modules 500 and 1000 arranged in a horizontal alignment, but they can also be arranged in a vertical alignment or a diagonal alignment.

[0074] The portable electronic device 1 may consist only of a camera module 1000 with zoom functionality.

[0075] At least one of the plurality of camera modules 500 and 1000 may be camera module 1000 according to the example in this disclosure, which will be referred to below including Figure 2 The accompanying drawings illustrate the use of a variety of figures. Specifically, in the case where the portable electronic device has a dual-camera module, according to the examples in this disclosure, at least one of the two camera modules can be provided as camera module 1000.

[0076] Based on various examples, camera modules and portable electronic devices including such camera modules can be implemented to have functions such as autofocus, zoom, and optical image stabilization, while having a simple structure and reduced size. Furthermore, power consumption can be minimized.

[0077] A camera module 1000 with zoom function can be installed in a portable electronic device 1 to capture images of objects.

[0078] The camera module 1000 may include a plurality of lenses, and the optical axis (z-axis) of each lens may be oriented in a direction perpendicular to the thickness direction of the portable electronic device 1 (y-axis direction, or the direction from the front surface to the rear surface of the portable electronic device 1 or the opposite direction).

[0079] As an example, the optical axis (z-axis) of each of the multiple lenses included in the camera module 1000 can be formed in the width or length direction of the portable electronic device 1.

[0080] Therefore, although the camera module 1000 has functions such as autofocus (AF), zoom, and optical image stabilization (OIS), the thickness of the portable electronic device 1 can remain unchanged. Thus, the portable electronic device 1 can have a small thickness.

[0081] When using two camera modules, the light entrances in the two camera modules can be arranged as close to each other as possible.

[0082] The first camera module 1000 and the second camera module 500 can have different perspectives.

[0083] The first camera module 1000 can be configured to have a relatively narrow field of view (e.g., a telephoto camera), and the second camera module 500 can be configured to have a relatively wide field of view (e.g., a wide-angle camera). The first camera module 1000 can be, as will be referred to below, including... Figure 2 The attached diagram describes the camera module.

[0084] As an example, the first camera module 1000 may be configured to have a field of view in the range of 9° to 35°, and the second camera module 500 may be configured to have a field of view in the range of 60° to 120°.

[0085] By designing the two camera modules to have different perspectives as described above, images of objects can be captured at various depths, and the captured images can be combined or superimposed to achieve various images.

[0086] The camera module 1000 may have AF, zoom, and OIS functions. Specifically, the camera module 1000 can achieve high-performance zoom by implementing multiple lens modules that can move along the optical axis over a long distance.

[0087] Because the camera module 1000, which includes AF, zoom, OIS and other functions, needs to include various components, the camera module 1000 may have a larger size than a typical camera module.

[0088] The increased size of the camera module 1000 may cause problems in reducing the size of the portable electronic device 1 in which the camera module 1000 is mounted.

[0089] For example, a camera module may have an increased number of stacked lenses for zoom functionality. When multiple lenses are stacked along the thickness of a portable electronic device, the thickness of the device may also increase depending on the number of stacked lenses. Therefore, unless the thickness of the portable electronic device is increased, it may not be possible to effectively ensure the number of stacked lenses, leading to a deterioration in zoom performance.

[0090] Furthermore, to achieve AF, zoom, and OIS functions, actuators are required to move multiple lens groups either along or perpendicular to the optical axis. When the optical axis (z-axis) of the lens groups is formed along the thickness direction of the portable electronic device, the actuators for moving the lens groups also need to be mounted along the thickness direction of the portable electronic device. Therefore, the thickness of the portable electronic device may increase.

[0091] However, since the camera module 1000 is arranged such that the optical axis (z-axis) of each of the multiple lenses is perpendicular to the thickness direction of the portable electronic device 1, the portable electronic device 1 can have a small thickness even though the camera module 1000 with AF, zoom and OIS functions is installed in the portable electronic device 1.

[0092] Figure 2 It is based on a stereoscopic view of the example camera module, and Figure 3 When only the cover is removed from the camera module Figure 2 An exploded 3D diagram.

[0093] refer to Figure 2 and Figure 3 The camera module 1000 may include a reflection module 1100, a lens module 1200, and an image sensor module 1300 disposed in the housing 1010.

[0094] The reflection module 1100 can be configured to change the direction of light propagation. For example, the direction of light incident from above through the opening 1031 of the cover 1030 of the camera module 1000 can be changed by the reflection module 1100 so that the light is directed toward the lens module 1200. For this purpose, the reflection module 1100 may include a light path changing member 1110 that changes the path of light (e.g., reflects light). The light path changing member 1110 can be variously applied, such as a mirror, prism, or beam splitter.

[0095] For example, the path of light incident on camera module 1000 in the thickness direction (y-axis direction) can be changed by reflection module 1100 to be approximately aligned with the optical axis direction (z-axis direction). Then, the light with its changed path is incident on lens module 1200.

[0096] Lens module 1200 may include multiple lenses through which light whose propagation direction is altered by reflection module 1100 passes. Lens module 1200 may include a first lens module 1210, a second lens module 1220, and a third lens module 1230. Although this example includes three lens modules, the number of lens modules is generally two or more.

[0097] The autofocus (AF) function and zoom function can be achieved by moving at least one of the multiple lens modules 1210, 1220 and 1230 in the optical axis direction (z-axis direction).

[0098] All three lens modules 1210, 1220 and 1230 can be moved in the optical axis direction, or any one of the three lens modules 1210, 1220 and 1230 (e.g. lens module 1230) can be fixed so as not to move in the optical axis direction, and the autofocus (AF) function and zoom function can be implemented by moving the lens modules (e.g. lens modules 1210 and 1220).

[0099] Image sensor module 1300 may include image sensor 1310 that converts light passing through multiple lenses into electrical signals (e.g., see image sensor 1310). Figure 5 ) and a printed circuit board 1320 on which an image sensor 1310 is mounted.

[0100] Image sensor module 1300 may include a filter 1340 for filtering light incident upon it after passing through lens module 1200 (e.g., see...). Figure 5 Filter 1340 can be an infrared cutoff filter.

[0101] Inside the housing 1010, the reflection module 1100 can be positioned in front of the lens module 1200 and the image sensor module 1300 can be positioned behind the lens module 1200.

[0102] Inside the housing 1010, there may be a motherboard 1070 that supplies power to the first drive unit 1140 of the reflection module 1100 and the second drive unit 1240 of the lens module 1200, a printed circuit board 1320 that sends and receives control signals to the image sensor 1310 of the image sensor module 1300, and a single terminal 1325 that connects to both the printed circuit board 1320 and the motherboard 1070.

[0103] Figure 4A and Figure 4B It is a stereoscopic view of the camera module based on other examples.

[0104] refer to Figure 4A In addition to the housing being set separately for each module, according to another example, camera module 1001 can have the same basic structure as camera module 1000.

[0105] In the following text, for the purpose of describing various examples, different reference numerals (e.g., “1000” in the examples and “1001” or “1002” in other examples) may be used for the corresponding camera modules, but all camera modules indicated by those reference numerals fall within the scope of the camera module indicated by “1000” according to this example.

[0106] That is, both camera module 1000 and camera module 1001 according to this example include a reflection module 1100, a lens module 1200 and an image sensor module 1300. However, in the above-mentioned camera module 1000 according to the example, the reflection module 1100, the lens module 1200 and the image sensor module 1300 can all be disposed in a single housing 1010, or only the image sensor module 1300 can be disposed separately.

[0107] Conversely, in camera module 1001 according to another example, reflection module 1100 and lens module 1200 can be disposed in separate housings. That is, reflection module 1100 can be disposed in first housing 1010a, and lens module 1200 can be disposed in second housing 1010b.

[0108] The image sensor module 1300 can be disposed together with the lens module 1200 in the second housing 1010b, or it can be disposed separately in the third housing 1010c.

[0109] When the first housing 1010a to the third housing 1010c are aligned sequentially in the optical axis direction (z-axis direction), they can be connected to each other in various ways, for example, by bonding them together with adhesive or by mechanically connecting them together by using hooks.

[0110] The cover 1030 can cover the entire upper part of the first housing 1010a to the third housing 1010c that are connected to each other. Although not shown, the cover 1030 can also be provided individually for each housing or selectively cover only two housings together.

[0111] This example covers structures in which housing 1010 is of an integral type and structures in which housing 1010 includes multiple housings 1010a, 1010b, and 1010c separately provided for corresponding modules. In the following detailed description of each component, it will be substantially assumed that housing 1010 has an integral structure; however, even if the housing is not explicitly described as being of a separable type, structures in which the housing has separable structures fall within the scope of this disclosure.

[0112] For further reference Figure 4B Except for the additional optical path alteration component 1410 disposed in the housing 1010, the camera module 1002, according to another example, can have the same basic structure as the camera module 1000.

[0113] That is, both camera modules 1000 and 1002 include a reflection module 1100, a lens module 1200, and an image sensor module 1300. However, in the camera module 1000, a single reflection module 1100 can be housed in a single housing 1010.

[0114] Conversely, camera module 1002 may include a first reflection module 1100 and one or more second reflection modules 1400 capable of further altering the optical path.

[0115] OIS functionality can be provided in any of the multiple reflection modules 1100 and 1400, or each of the reflection modules 1100 and 1400 can be responsible for a portion of the OIS functionality such that the OIS functionality is shared by the reflection modules 1100 and 1400. For example, the optical path changing member 1110 of the first reflection module 1100 can be driven to rotate relative to a first axis perpendicular to the optical axis, and the optical path changing member 1410 of the second reflection module 1400 can be driven to rotate relative to a second axis perpendicular to both the optical axis and the first axis.

[0116] Light incident on camera module 1002 can be incident on image sensor module 1300 after its optical path is changed at least twice by reflection modules 1100 and 1400.

[0117] For further reference Figures 5 to 15 The camera module 1000 may include a reflection module 1100, a lens module 1200, and an image sensor module 1300 disposed in the housing 1010.

[0118] The reflection module 1100, the lens module 1200, and the image sensor module 1300 can be arranged sequentially from one side to the other within the housing 1010.

[0119] The housing 1010 may have an internal space in which the reflection module 1100, the lens module 1200 and the image sensor module 1300 are arranged.

[0120] For example, as shown in the accompanying drawings, both the reflection module 1100 and the lens module 1200 can be arranged within the interior space of the housing 1010. However, the configuration of the housing 1010 is not limited to this. For example, as described above, separate housings in which the reflection module 1100 and the lens module 1200 are respectively arranged can be connected to each other.

[0121] The housing 1010 can be covered by the cover 1030 so that light is blocked and the interior space of the housing 1010 is not visible.

[0122] The cover 1030 may have an opening 1031 to allow light to pass through it, and the propagation direction of the light incident through the opening 1031 may be changed by the reflection module 1100 so that the light is incident on the lens module 1200. The cover 1030 may be configured as a whole to completely cover the housing 1010, or it may be configured to cover separate components of the reflection module 1100 and the lens module 1200 respectively.

[0123] The reflection module 1100 may include a light path changing component 1110. The light path changing component 1110 may be a prism, beam splitter, mirror, etc.

[0124] After passing through multiple lenses (e.g., lenses included in three lens modules 1210, 1220 and 1230), the light incident on the lens module 1200 can be converted by the image sensor 1310 and stored as an electrical signal.

[0125] The reflection module 1100 can be disposed in the front part of the interior space of the housing 1010, that is, near the opening 1031 through which incident light passes, and the lens module 1200 can be disposed in the rear part of the interior space of the housing 1010, that is, near the image sensor 1310 in which light forms an image.

[0126] The space for arranging the lens module 1200 can be separated by a first protruding wall 1009 in the housing 1010. The first protruding wall 1009 can protrude from the side wall of the housing 1010 toward the interior space on both sides of the housing 1010.

[0127] The reflective module 1100 may include a rotating bracket 1120, and the housing 1010 and the rotating bracket 1120 facing each other may be configured to have a first magnetic material 1151 and a second magnetic material 1153 on their respective facing surfaces, and the rotating bracket 1120 may be supported by the housing 1010 by the magnetic force between the first magnetic material 1151 and the second magnetic material 1153 (attached to the housing 1010).

[0128] The first magnetic material 1151 and the second magnetic material 1153 can be a traction yoke and a traction magnet. For example, the first magnetic material 1151 and the second magnetic material 1153 can be selectively a traction yoke and a traction magnet, or both the first magnetic material 1151 and the second magnetic material 1153 can be traction magnets.

[0129] The first spherical component 1131, the rotating plate 1130, and the second spherical component 1133 can be disposed between the inner wall surface of the housing 1010 and the rotating support 1120.

[0130] A damper 1050 can be installed in the first protruding wall 1009 of the housing 1010.

[0131] The damper 1050 can be fitted into the first protruding wall 1009 of the housing 1010.

[0132] For example, such as Figure 29AAs shown, each of the dampers 1050 may include a frame 1051 fitted into the first protruding wall 1009 and an extension 1052 extending from the frame 1051. Damping material 1053 may be disposed on the extension 1052 to protrude toward the rotating support 1120 in the optical axis direction.

[0133] The damping material 1053 can be inserted into the through hole 1055 provided in the extension portion 1052 or can be attached to the extension portion 1052 using an adhesive. As long as the damping material 1053 is elastic, it can be any material, such as polyurethane, silicone, epoxy, or polyethylene.

[0134] Each of the first protruding walls 1009 of the housing 1010 may have an insertion recess 1019 into which a frame 1051 is fitted. A hook-shaped frame 1051 may be fitted downwards into the first protruding wall 1009 from above, and the hook-shaped frame 1051 may be engaged by the upper portion of the first protruding wall 1009 for fixation without movement (press-fit or sliding connection). Furthermore, an adhesive may be applied between the frame 1051 and the housing 1010 to further connect the frame 1051 and the housing 1010 to each other by bonding.

[0135] The damping material 1053 can be configured to be fitted into a through hole 1055 provided in the extension portion 1052 (or, the damping material 1053 can be attached to one or both surfaces of the extension portion 1052 by using an adhesive), and the damping material 1053 can be configured to protrude from one or both surfaces of the extension portion 1052. The damping material 1053 can then be used as a damper to absorb vibrations of the rotating support 1120 or as a stop to limit the movement distance of the rotating support 1120.

[0136] The damper 1050 can be used to limit the range of motion of the rotating support 1120 or to absorb the vibration of the rotating support 1120. A space can be provided between the damper 1050 and the rotating support 1120 to allow the rotating support 1120 to rotate smoothly.

[0137] The reflection module 1100 can change the path of light incident upon it through the opening 1031. When capturing images or recording videos, images may be blurry or videos may be shaky due to user hand tremors, etc. In such cases, the reflection module 1100 can correct user hand tremors, etc., by moving the rotating bracket 1120 on which the optical path changing component 1110 is mounted.

[0138] For example, when a user's hand shakes while taking an image or recording a video, the shaking can be compensated by providing a relative displacement corresponding to the shaking to the rotating bracket 1120.

[0139] Furthermore, since the OIS function can be implemented by moving the relatively lightweight rotating bracket 1120, power consumption can be minimized.

[0140] That is, in order to achieve the OIS function, optical image stabilization can be performed by moving the rotating bracket 1120 in which the optical path changing component 1110 is set, without moving the lens module including multiple lenses or image sensors, to change the direction of light propagation.

[0141] The reflection module 1100 may include a rotating bracket 1120, an optical path changing component 1110, and a first driving unit 1140. The rotating bracket 1120 is positioned in a supporting manner and faces the housing 1010. The optical path changing component 1110 is installed in the rotating bracket 1120. The first driving unit 1140 moves the rotating bracket 1120. A rotating plate 1130 may be arranged between the housing 1010 and the rotating bracket 1120.

[0142] The light path changing component 1110 can change the direction of light propagation. For example, the light path changing component 1110 can be a mirror, prism, beam splitter, etc. that reflects light (for ease of explanation, the light path changing component 1110 is shown as a prism in the accompanying drawings related to the exemplary embodiment).

[0143] The optical path alteration component 1110 can be fixed to the rotating bracket 1120. The rotating bracket 1120 can have a mounting surface 1123 on which the optical path alteration component 1110 is mounted.

[0144] The mounting surface 1123 of the rotating bracket 1120 can be an inclined surface that alters the path of light. For example, the mounting surface 1123 can be a surface inclined at an angle ranging from 30° to 60° relative to the optical axis (z-axis) of each of the plurality of lenses. The inclined surface of the rotating bracket 1120 can face the light passing through the incident opening 1031 of the cover 1030.

[0145] The rotating bracket 1120 on which the optical path changing component 1110 is mounted can be movably housed within the interior space of the housing 1010. For example, the rotating bracket 1120 can be housed within the housing 1010 to be able to rotate about a first axis and about a second axis. Here, both the first and second axes can be perpendicular to the optical axis (z-axis), and the first and second axes can be perpendicular to each other. For example, the first axis can be parallel to the x-axis shown in the figures, and the second axis can be parallel to the y-axis shown in the figures.

[0146] The rotating bracket 1120 can be arranged in a supporting manner while facing the housing 1010, wherein the first ball member 1131 and the second ball member 1133 are inserted between the rotating bracket 1120 and the housing 1010, the first ball member 1131 being aligned along a first axis and the second ball member 1133 being aligned along a second axis such that the rotating bracket 1120 can rotate smoothly using each of the first axis and the second axis as a rotation axis.

[0147] As an example, the accompanying drawings show two first ball members 1131 arranged spaced apart from each other along a first axis and two second ball members 1133 arranged spaced apart from each other along a second axis. The rotating support 1120 can be rotated relative to the first and second axes by means of a first drive unit 1140 described below.

[0148] The first ball member 1131 and the second ball member 1133 can be respectively disposed on the front and rear surfaces of the rotating plate 1130. Alternatively, the first ball member 1131 and the second ball member 1133 can be disposed on the rear and front surfaces of the rotating plate 1130 by reversing their positions. That is, the first ball member 1131 can be aligned along a second axis, and the second ball member 1133 can be aligned along a first axis. For ease of explanation, the following description will be based on the structure shown in the accompanying drawings. The rotating plate 1130 can be disposed between the rotating support 1120 and the inner surface of the housing 1010.

[0149] The rotating bracket 1120 can be supported by the housing 1010 via the rotating plate 1130 by the magnetic force between the first magnetic material 1151 disposed on the rotating bracket 1120 and the second magnetic material 1153 disposed on the housing 1010.

[0150] The rotating bracket 1120 may include a first extension 1129 extending on both sides of the rotating bracket 1120 in a direction toward the surface supported by the housing 1010 (e.g., the optical axis direction).

[0151] The rotating plate 1130 can be arranged to be positioned between the first extensions 1129 disposed on both sides of the rotating support 1120. The housing 1010 may include a recessed portion 1018 recessed in the optical axis direction (z-axis direction) on its inner surface to ensure space for easy movement of the first extensions 1129.

[0152] According to this structure, as will be described below, it is possible to ensure a space for easily arranging two first-1 magnets 1141a and 1143a and two first-2 magnets 1145a and 1147a that are arranged parallel to each other on the side surface of the rotating bracket 1120, and it is also possible to provide a space in which the zoom driver can become long enough by positioning the rotating bracket 1120 and the rotating plate 1130 to partially overlap each other in the optical axis direction (z-axis direction).

[0153] The rotating bracket 1120 may include a recessed portion 1128 and a second extension portion 1127, wherein the recessed portion 1128 is in the direction in which the optical path changing member 1110 is mounted toward the image sensor (e.g., toward the first protruding wall 1009 of the housing 1010) to minimize the space thus occupied in the optical axis direction (z-axis direction), and the second extension portion 1127 protrudes toward the image sensor in the optical axis direction (z-axis direction) while the optical path changing member 1110 is mounted in a portion other than the recessed portion 1128.

[0154] Then, the groove portion 1128 may face the first protruding wall 1009 of the housing 1010 in the optical axis direction (z-axis direction), and the second extension portion 1127 may be partially arranged at the same position as the first protruding wall 1009 in the optical axis direction (z-axis direction) (i.e., the second extension portion 1127 and the first protruding wall 1009 may be arranged to overlap each other in the x-axis direction), or the second extension portion 1127 may be arranged to be adjacent to the first protruding wall 1009 in the optical axis direction (z-axis direction).

[0155] The second extension 1127 can be configured to be smaller in the x-axis direction than the distance between the ends of the opposing first protruding walls 1009 that protrude from both sides of the housing 1010 inside the housing 1010. That is, the width of the second extension 1127 in the x-axis direction can be smaller than the distance between the ends of the opposing first protruding walls 1009 in the x-axis direction, and therefore, the second extension 1127 can be arranged between the opposing first protruding walls 1009.

[0156] By providing recessed portions 1128 on both sides of the rotating bracket 1120 as described above, the rotating bracket 1120 can occupy a substantially minimal space in the optical axis direction (z-axis direction), and the rotating bracket 1120 can be arranged at the same position as the first protruding wall 1009 in the optical axis direction (z-axis direction), or arranged to be adjacent to the first protruding wall 1009 in the optical axis direction (z-axis direction). Therefore, it is possible to additionally provide space in which the zoom driver can become sufficiently long.

[0157] Guide grooves 1132 and 1134 may be provided in the front and rear surfaces of the rotating plate 1130 to insert the first ball member 1131 and the second ball member 1133 therein, and guide grooves 1132 and 1134 may include a first guide groove 1132 in which the first ball member 1131 is partially inserted and a second guide groove 1134 in which the second ball member 1133 is partially inserted.

[0158] The housing 1010 may have a third guide groove 1021 in which a first ball member 1131 is partially inserted, and the rotating bracket 1120 may have a fourth guide groove 1121 in which a second ball member 1133 is partially inserted.

[0159] The first guide groove 1132, the second guide groove 1134, the third guide groove 1021 and the fourth guide groove 1121 mentioned above can be hemispherical or polygonal (polyhedral or pyramidal) in shape, so that the first spherical component 1131 and the second spherical component 1133 can be rotated easily.

[0160] The first ball member 1131 and the second ball member 1133 can be used as bearings by rolling or sliding in the first guide groove 1132, the second guide groove 1134, the third guide groove 1021 and the fourth guide groove 1121.

[0161] like Figure 13 and Figure 15 As shown, the first ball member 1131a and the second ball member 1133a can be fixedly disposed on two surfaces of the rotating plate 1130 or disposed on a corresponding surface of the housing 1010 and the rotating support 1120 facing the rotating plate 1130.

[0162] The first drive unit 1140 can generate a driving force that allows the rotating bracket 1120 to rotate relative to two axes.

[0163] As an example, the first drive unit 1140 may include a plurality of magnets 1141a, 1143a, 1145a and 1147a and a plurality of coils 1141b, 1143b, 1145b and 1147b arranged to face the plurality of magnets 1141a, 1143a, 1145a and 1147a.

[0164] Furthermore, multiple magnets 1141a, 1143a, 1145a, and 1147a can be individually disposed on two side surfaces of the rotating bracket 1120, i.e., on surfaces parallel to the yz plane. In this way, multiple magnets 1141a, 1143a, 1145a, and 1147a and multiple coils 1141b, 1143b, 1145b, and 1147b can be arranged on the side surfaces of the rotating bracket 1120 and on the side surfaces of the housing 1010 facing the rotating bracket 1120, and the multiple magnets 1141a, 1143a, 1145a, and 1147a and multiple coils 1141b, 1143b, 1145b, and 1147b are not arranged on the bottom or top surface of the housing 1010. Therefore, the overall thickness (i.e., the length in the y-axis direction) of the camera module 1000 can be reduced, referring to... Figure 1 This is advantageous in that the camera module 1000 can be easily installed even when the portable electronic device 1 has a small thickness.

[0165] As will be described below, all of the plurality of magnets 1241a and 1243a and the plurality of coils 1241b and 1243b included in the second drive unit 1240 may also be disposed on the side surface of the housing 1010, which also helps to reduce the overall thickness (i.e., the length in the y-axis direction) of the camera module 1000.

[0166] like Figure 1 As shown, the camera module 1000 can be arranged such that the bottom surface of the housing 1010 faces the display (screen) of the portable electronic device 1. When the first drive unit 1140 or the second drive unit 1240 is disposed on the side surface of the housing 1010, the magnetic flux leakage in the direction toward the display (screen) can be suppressed as much as possible, thereby minimizing the impact of the magnetic flux on the function of the portable electronic device 1.

[0167] Among the multiple magnets, one of the first-1 magnets 1141a and 1143a and one of the first-2 magnets 1145a and 1147a can be arranged parallel to each other on a side surface of the rotating support 1120. The first-1 magnets 1141a and 1143a and the first-2 magnets 1145a and 1147a can be magnetized such that their coil-facing surfaces have N and S poles in directions perpendicular to each other. For example, the first-1 magnets 1141a and 1143a can be magnetized to have N and S poles along the optical axis direction (z-axis direction), and the first-2 magnets 1145a and 1147a can be magnetized to have N and S poles along the y-axis direction perpendicular to the optical axis (z-axis).

[0168] When electricity is applied to multiple coils 1141b, 1143b, 1145b and 1147b, a rotating support 1120 on which multiple magnets 1141a, 1143a, 1145a and 1147a are mounted can rotate relative to a first axis (x-axis) and a second axis (y-axis) by the electromagnetic force between the multiple magnets 1141a, 1143a, 1145a and 1147a and the multiple coils 1141b, 1143b, 1145b and 1147b.

[0169] Multiple coils 1141b, 1143b, 1145b, and 1147b can be mounted on housing 1010. As an example, multiple coils 1141b, 1143b, 1145b, and 1147b can be mounted on housing 1010 while multiple coils 1141b, 1143b, 1145b, and 1147b are mounted on motherboard 1070.

[0170] That is, multiple coils 1141b, 1143b, 1145b and 1147b can be disposed on the main board 1070, the main board 1070 can be attached to the outer surface of the housing 1010, and the multiple coils 1141b, 1143b, 1145b and 1147b can be exposed to the interior of the housing 1010 through through holes 1010-1 and 1010-2 to face the multiple magnets 1141a, 1143a, 1145a and 1147a.

[0171] Here, although the motherboard 1070 is shown in the accompanying drawings as an integral unit, such that the coils for the reflection module 1100 and the coils for the lens module 1200 are both mounted thereon, the motherboard 1070 may be configured to have two or more separate boards on which the coils for the reflection module 1100 and the coils for the lens module 1200 are mounted respectively.

[0172] A closed-loop control method can be used. In the closed-loop control method, the position of the rotating bracket 1120 can be detected when the rotating bracket 1120 rotates, and feedback related to the detected position can be given.

[0173] For closed-loop control, position detection sensors 1141c, 1143c, 1145c, and 1147c may be required. Each of the position detection sensors 1141c, 1143c, 1145c, and 1147c can be a Hall sensor, a TMR sensor, a magnetic sensor, etc.

[0174] Position detection sensors 1141c, 1143c, 1145c and 1147c can be arranged inside or outside coils 1141b, 1143b, 1145b and 1147b respectively, and can be mounted on motherboard 1070 together with coils 1141b, 1143b, 1145b and 1147b respectively.

[0175] Position detection sensors 1141c, 1143c, 1145c and 1147c can interact with any or both of the first-1 magnets 1141a and 1143a and the first-2 magnets 1145a and 1147a, which are driving magnets, or they can interact with a separately provided sensing magnet 1149a.

[0176] The motherboard 1070 may be equipped with a gyroscope sensor (not shown) that senses jitter factors such as the user's hand tremors, and may be equipped with a driver integrated circuit (IC) (not shown) that provides drive signals to multiple coils 1141b, 1143b, 1145b and 1147b.

[0177] When the rotating support 1120 rotates relative to the first axis (x-axis), the rotating plate 1130 can rotate while being supported by the first ball members 1131 arranged along the first axis (x-axis) (in this case, the rotating support 1120 does not move relative to the rotating plate 1130).

[0178] When the rotating support 1120 rotates relative to the second axis (y-axis), the rotating support 1120 can rotate by moving on the second ball member 1133 arranged along the second axis (y-axis) (in this case, since the rotating plate 1130 does not rotate, the rotating support 1120 can move relative to the rotating plate 1130).

[0179] That is, when rotating relative to the first axis (x-axis), the rotating plate 1130 can rotate together with the rotating support 1120, and when rotating relative to the second axis (y-axis), the rotating plate 1130 can rotate separately from the rotating support 1120.

[0180] When rotated relative to the first axis (x-axis), the first ball member 1131 can form a rotation axis, and when rotated relative to the second axis (y-axis), the second ball member 1133 can form a rotation axis.

[0181] This is because, as shown in the attached figure, when the rotating bracket 1120 rotates relative to the first axis (x-axis), the second ball members 1133 aligned on the second axis (y-axis) can remain stationary while they are inserted into the guide groove, and when the rotating bracket 1120 rotates relative to the second axis (y-axis), the first ball members 1131 aligned on the first axis (x-axis) can remain stationary while they are inserted into the guide groove.

[0182] This document describes the reflection module 1100 based on the following assumption: the rotating bracket 1120, which is provided with the optical path changing member 1110, rotates in a supported state via the ball member 1131 or 1133, wherein the ball member 1131 or 1133 is aligned in one direction on one surface of the housing 1010, but the configuration of the rotating bracket 1120 is not limited to this.

[0183] For example, the rotating bracket 1120 can 1) be able to rotate while suspended from the housing by a spring, 2) be rotatably fixed to the housing by a hinge-type rotating member, 3) be pivotally mounted on the housing so as to be able to rotate relative to an axis, or 4) be able to rotate while supported by the housing by a ball member that moves by sliding or rotating along a curved ball guide.

[0184] Figure 9 It is a perspective view of the housing of the camera module, where the reflection module and lens module are connected to the camera module, based on the example. Figure 10 This is a perspective view of the housing of a camera module, based on another example, in which the reflection module and lens module are connected to the camera module.

[0185] refer to Figure 9 and Figure 10 They disclosed how to implement AF, zoom, and OIS functions in the camera module 1000.

[0186] Light whose path has been altered by the reflection module 1100 can then be incident on the lens module 1200. The incident light can then be incident on the three lens modules 1210, 1220, and 1230 along the optical axis (z-axis) to achieve AF or zoom functionality.

[0187] refer to Figure 9 For example, two rear lens modules 1210 and 1220 can be responsible for zoom function, and a front lens module 1230 can be responsible for autofocus function.

[0188] Or, refer to Figure 10 The two rear lens modules 1210 and 1220 can be responsible for zoom and autofocus functions, and a front lens module 1230 can be arranged as a fixed component. For example, the two rear lens modules 1210 and 1220 can be combined together to be responsible for zoom function, and the last lens module 1210 can be responsible for autofocus function.

[0189] The configuration of the three lens modules 1210, 1220 and 1230 is not limited to this, and they can be combined in various ways to handle zoom and autofocus functions individually or together.

[0190] The space for one front lens module 1230 and two rear lens modules 1210 and 1220 can be separated by the second protruding wall 1008. However, the configuration of the three lens modules 1210, 1220 and 1230 is not limited to this, and they can all be arranged in the same space or in different separated spaces.

[0191] For further reference Figures 16 to 20 The lens module 1200, which enables AF and zoom functions, and the first lens module 1210 and the second lens module 1220 are driven by the second drive unit 1240.

[0192] Lens module 1200 may include two lens modules configured to be movable in the optical axis direction (z-axis direction) within the internal space of housing 1010: a first lens module 1210 and a second lens module 1220. The two lens modules 1210 and 1220 may then be moved relative to housing 1010 in the optical axis direction (z-axis direction) by a second drive unit 1240.

[0193] The first lens module 1210 and the second lens module 1220 can be configured to move approximately in the optical axis direction (z-axis direction) to achieve AF function or zoom function.

[0194] Therefore, the second drive unit 1240 can generate a driving force that allows each of the first lens module 1210 and the second lens module 1220 to move in the optical axis direction (z-axis direction). That is, the second drive unit 1240 can move each of the first lens module 1210 and the second lens module 1220 individually in the optical axis direction (z-axis direction) to achieve AF function or zoom function.

[0195] The first lens module 1210 and the second lens module 1220 can be mounted on the bottom surface of the housing 1010 in a supported manner. For example, the first lens module 1210 and the second lens module 1220 can each be individually supported by the bottom surface of the housing 1010 via a ball member or a shaft.

[0196] The first lens module 1210 is disposed in the housing 1010 so that it can move in the optical axis direction (z-axis direction). As an example, a first axis 1215a and a third spherical member 1215b may be disposed between the first lens module 1210 and the bottom surface of the housing 1010.

[0197] The first lens module 1210 can move in the optical axis direction (z-axis direction) on the first axis 1215a and the third ball member 1215b. The first axis 1215a is fixedly arranged to extend in the optical axis direction (z-axis direction) on one side of the bottom surface of the housing 1010, and the third ball member 1215b is arranged to move by rolling in the optical axis direction (z-axis direction) on the other side of the bottom surface of the housing 1010.

[0198] The first lens module 1210 can be configured to move by sliding on the first axis 1215a and by rolling of the third ball member 1215b.

[0199] The first shaft 1215a and the third ball member 1215b can be arranged in the fifth guide grooves 1013a and 1013b, which are provided on both sides of the bottom surface of the housing 1010 and extend in the optical axis direction (z-axis direction).

[0200] The first shaft 1215a can be pressed and supported by stops 1060-1061 in the stops 1060 described below to secure it to the 5-1 guide groove 1013a, or it can be secured by bonding with a separate adhesive. Furthermore, the third ball member 1215b can be moved by rolling within the 5-2 guide groove 1013b.

[0201] The first shaft 1215a and the third ball component 1215b can be accommodated in the fifth guide grooves 1013a and 1013b and arranged between the first lens module 1210 and the housing 1010.

[0202] The fifth guide grooves 1013a and 1013b can be formed to extend in the optical axis direction (z-axis direction). Each of the fifth guide grooves 1013a and 1013b can have a cross-section of various shapes, such as circular, V-shaped and polygonal.

[0203] The sixth guide grooves 1214a and 1214b, into which the first shaft 1215a and the third ball member 1215b are inserted, can be provided in the lower surface of the first lens module 1210 facing the bottom surface of the housing 1010. Each of the sixth guide grooves 1214a and 1214b can have a cross-section of various shapes, such as circular, V-shaped and polygonal.

[0204] As will be described below, the first bearing member 1218 supporting the first shaft 1215a can be arranged at two points spaced apart from each other in the optical axis direction (z-axis direction) in the 6-1 guide groove 1214a.

[0205] The two first bearing components 1218 can be bonded to the 6-1 guide groove 1214a using an adhesive, or they can be integrally manufactured with the first lens module 1210 by inserting the two first bearing components 1218 into a mold during the manufacture of the first lens module 1210.

[0206] Sliding friction can occur between the first shaft 1215a and the first bearing member 1218.

[0207] The two first bearing members 1218 can be arranged in the 6-1 guide groove 1214a, spaced apart from each other in the optical axis direction (z-axis direction) to contact the first shaft 1215a on both sides.

[0208] The first shaft 1215a can contact only the two first bearing members 1218 without contacting the 6-1 guide groove 1214a, thereby reducing the friction caused when the first lens module 1210 moves by sliding.

[0209] Therefore, the first lens module 1210 can form a three-point support structure by contacting a first contact point CS1 of a third spherical member 1215b, and by contacting the second contact points CS2 and third contact points CS3 of two first bearing members 1218 spaced apart in the optical axis direction (z-axis direction) with the first shaft 1215a (see...). Figure 23 ).

[0210] The first lens module 1210 can be pressed toward the bottom of the housing 1010 to maintain contact between the housing 1010 and the third ball member 1215b, and between the housing 1010 and the first shaft 1215a.

[0211] Therefore, the third magnetic material 1016 and the fourth magnetic material 1216 can optionally be disposed on the bottom surface of the housing 1010 and the lower surface of the first lens module 1210 facing the bottom surface of the housing 1010, respectively, and the first lens module 1210 can be pressed towards the bottom surface of the housing 1010 by the magnetic force between the third magnetic material 1016 and the fourth magnetic material 1216. The magnetic force can be generated between the third magnetic material 1016 and the fourth magnetic material 1216 in a direction perpendicular to the optical axis (e.g., the y-axis direction).

[0212] The third magnetic material 1016 and the fourth magnetic material 1216 can be a traction yoke and a traction magnet. For example, the third magnetic material 1016 and the fourth magnetic material 1216 can optionally be a traction yoke and a traction magnet, or both the third magnetic material 1016 and the fourth magnetic material 1216 can be traction magnets.

[0213] The third magnetic material 1016 can be disposed on the bottom surface of the housing 1010 to extend along the optical axis (z-axis direction) along the moving path of the first lens module 1210, and the fourth magnetic material 1216 can be disposed on the lower surface of the first lens module 1210 to face the third magnetic material 1016. Considering the moving path of the first lens module 1210, the third magnetic material 1016 can be configured to extend sufficiently in the optical axis (z-axis direction) to continuously face the fourth magnetic material 1216.

[0214] The third magnetic material 1016 can be attached to the outer surface of the housing 1010 and exposed to the interior space of the housing 1010 through a magnetic material hole 1016a provided at the bottom of the housing 1010. Alternatively, the third magnetic material 1016 can be attached to the inner bottom surface of the housing 1010 or inserted into the bottom surface of the housing 1010.

[0215] After the first lens module 1210 moves along the optical axis (z-axis direction), it can form a stable three-point support structure at any position.

[0216] That is, such as Figures 23 to 25 As shown, the first lens module 1210 can move in the optical axis direction (z-axis direction). Figure 23 Approximately the middle position in Figure 24 The leftmost position in the middle and Figure 25 (The rightmost position in the middle).

[0217] Furthermore, the center MC4 of the magnetic force caused by the fourth magnetic material 1216 can be located within the triangle formed by the first contact point CS1 where the first lens module 1210 contacts the third ball member 1215b, and the second contact point CS2 and the third contact point CS3, which are the two points where the first lens module 1210 contacts the first axis 1215a.

[0218] The center of the magnetic force exerted by the fourth magnetic material 1216 can be, for example, the geometric center of the surface of the fourth magnetic material 1216 facing the third magnetic material 1016. Figure 23 As seen, the geometric center of the fourth magnetic material 1216 can refer to the approximate centroid of the fourth magnetic material 1216 in the xz plane.

[0219] The coil 1241b for driving the first lens module 1210 can be disposed on one of the opposite side surfaces of the housing 1010. In this case, electromagnetic force acts on one side surface of the first lens module 1210. Therefore, in order to easily drive the first lens module 1210, the third magnetic material 1016 and the fourth magnetic material 1216 can be disposed biased toward one side surface of the housing 1010, that is, the side where the coil 1241b is located, rather than the center of the housing 1010.

[0220] In order to increase the size of each of the magnets 1241a to improve the driving force, the first lens module 1210 may have a first support portion 1219 by extending the portion in which the magnets 1241a are mounted toward the second lens module 1220 in the optical axis direction (z-axis direction).

[0221] In addition, in order to increase the size of each of the magnets 1243a to improve the driving force, the second lens module 1220 may also have a second support portion 1229 by extending the portion of the first lens module 1210 in the optical axis direction (z-axis direction) into which the magnets 1243a are mounted.

[0222] The first support portion 1219 and the second support portion 1229 can extend in opposite directions.

[0223] The second lens module 1220 can be arranged in the housing 1010 so that it is movable in the optical axis direction (z-axis direction). As an example, the second lens module 1220 can be arranged in front of the first lens module 1210 in the optical axis direction (z-axis direction).

[0224] A second axis 1225a and a fourth ball component 1225b may be disposed between the second lens module 1220 and the bottom surface of the housing 1010.

[0225] The second lens module 1220 can move in the optical axis direction (z-axis direction) while being supported by the second shaft 1225a and the fourth ball member 1225b. The second shaft 1225a is fixedly arranged to extend in the optical axis direction (z-axis direction) on the other side of the bottom surface of the housing 1010, and the fourth ball member 1225b is arranged to move by rolling in the optical axis direction (z-axis direction) on one side of the bottom surface of the housing 1010.

[0226] That is, the second lens module 1220 can be configured to move by sliding on the second axis 1225a and by rolling of the fourth ball member 1225b.

[0227] The second shaft 1225a and the fourth ball member 1225b can be arranged in the seventh guide grooves 1014a and 1014b, which are provided on both sides of the bottom surface of the housing 1010 and extend in the optical axis direction (z-axis direction).

[0228] The second shaft 1225a can be pressed and supported by the stop 1062 in the stop 1060 described below to secure it to the 7-1 guide groove 1014a, or it can be secured by bonding with a separate adhesive. The fourth ball member 1225b can be moved by rolling in the 7-2 guide groove 1014b.

[0229] The second shaft 1225a and the fourth ball component 1225b can be accommodated in the seventh guide grooves 1014a and 1014b and arranged between the second lens module 1220 and the housing 1010.

[0230] The seventh guide grooves 1014a and 1014b can be formed to extend in the optical axis direction (z-axis direction). Each of the seventh guide grooves 1014a and 1014b can have a cross-section of various shapes, such as circular, V-shaped and polygonal.

[0231] The eighth guide grooves 1224a and 1224b, into which the second shaft 1225a and the fourth ball member 1225b are inserted, can be provided on the lower surface of the second lens module 1220 facing the bottom of the housing 1010. Each of the eighth guide grooves 1224a and 1224b can have a cross-section of various shapes, such as circular, V-shaped and polygonal.

[0232] The second bearing member 1228 supporting the second shaft 1225a can be arranged at two points spaced apart from each other in the optical axis direction (z-axis direction) in the guide groove 1224a of the 8-1.

[0233] The two second bearing components 1228 can be bonded to the 8-1 guide groove 1224a using an adhesive, or they can be integrally manufactured with the second lens module 1220 by inserting the two second bearing components 1228 into a mold during the manufacture of the second lens module 1220.

[0234] Sliding friction can occur between the second shaft 1225a and the second bearing member 1228.

[0235] Two second bearing members 1228 can be arranged in the 8-1 guide groove 1224a, spaced apart from each other in the optical axis direction (z-axis direction) to contact the second shaft 1225a on both sides.

[0236] The second shaft 1225a can contact only the two second bearing members 1228 without contacting the 8-1 guide groove 1224a, thereby reducing the friction caused when the second lens module 1220 moves by sliding.

[0237] Therefore, the second lens module 1220 can form a three-point support structure by contacting the fourth contact point CS4 of a fourth ball component 1225b, and by contacting the fifth contact point CS5 and the sixth contact point CS6 of two second bearing components 1228 spaced apart from each other in the optical axis direction (z-axis direction) with the second shaft 1225a.

[0238] The second lens module 1220 can be pressed toward the bottom of the housing 1010 to maintain contact between the housing 1010 and the fourth ball member 1225b, and between the housing 1010 and the second shaft 1225a.

[0239] Therefore, the fifth magnetic material 1017 and the sixth magnetic material 1226 can optionally be disposed on the bottom surface of the housing 1010 and the lower surface of the second lens module 1220 facing the bottom surface of the housing 1010, respectively, and the second lens module 1220 can be pressed against the bottom surface of the housing 1010 by the magnetic force between the fifth magnetic material 1017 and the sixth magnetic material 1226. The magnetic force can be generated between the fifth magnetic material 1017 and the sixth magnetic material 1226 in a direction perpendicular to the optical axis (e.g., the y-axis direction).

[0240] The fifth magnetic material 1017 and the sixth magnetic material 1226 can be a traction yoke and a traction magnet. For example, the fifth magnetic material 1017 and the sixth magnetic material 1226 can optionally be a traction yoke and a traction magnet, or both the fifth magnetic material 1017 and the sixth magnetic material 1226 can be traction magnets.

[0241] A fifth magnetic material 1017 can be disposed on the bottom surface of the housing 1010 to extend along the optical axis (z-axis direction) along the movement path of the second lens module 1220, and a sixth magnetic material 1226 can be disposed on the lower surface of the second lens module 1220 to face the fifth magnetic material 1017. Considering the movement path of the second lens module 1220, the fifth magnetic material 1017 can be arranged to extend sufficiently along the optical axis (z-axis direction) to continuously face the sixth magnetic material 1226.

[0242] The fifth magnetic material 1017 can be attached to the outer surface of the housing 1010 and exposed to the interior space of the housing 1010 through a magnetic material hole 1017a provided at the bottom of the housing 1010. Alternatively, the fifth magnetic material 1017 can be attached to the inner bottom surface of the housing 1010 or inserted into the bottom surface of the housing 1010.

[0243] The third magnetic material 1016 and the fifth magnetic material 1017, which are configured to extend along the moving path of the first lens module 1210 on the bottom surface of the housing 1010 in the optical axis direction (z-axis direction), can be set individually or as a whole (in the figures, only the third magnetic material 1016 and the fifth magnetic material 1017 are shown individually for convenience).

[0244] Furthermore, the second lens module 1220 can form a stable three-point support structure at any position after being moved in the optical axis direction (z-axis direction).

[0245] That is, such as Figures 23 to 25 As shown, the second lens module 1220 can move in the optical axis direction (z-axis direction). Figure 23 Approximately the middle position in Figure 24 The leftmost position in the middle and Figure 25 (The rightmost position in the middle).

[0246] The center of the magnetic force caused by the sixth magnetic material 1226, MC6, can be located within the triangle formed by the fourth contact point CS4 where the second lens module 1220 contacts the fourth ball member 1225b, and the fifth contact point CS5 and the sixth contact point CS6, which are the two points where the second lens module 1220 contacts the second axis 1225a.

[0247] The center of the magnetic force exerted by the sixth magnetic material 1226 can be, for example, the geometric center of the surface of the sixth magnetic material 1226 facing the fifth magnetic material 1017. (As from...) Figure 23 As seen, the geometric center of the sixth magnetic material 1226 can refer to the approximate centroid of the sixth magnetic material 1226 in the XZ plane.

[0248] The coil 1243b for driving the second lens module 1220 can be disposed on one of the opposite side surfaces of the housing 1010. In this case, electromagnetic force acts on one side surface of the second lens module 1220. Therefore, in order to easily drive the second lens module 1220, the fifth magnetic material 1017 and the sixth magnetic material 1226 can be disposed biased toward one side surface of the housing 1010, that is, the side where the coil 1243b is located, rather than the center of the housing 1010.

[0249] As described above, the first lens module 1210 and the second lens module 1220 can move along the optical axis (z-axis direction) on different spherical components and axes. This is to enable each of the first lens module 1210 and the second lens module 1220 to move a long distance along the optical axis (z-axis direction) to achieve a long stroke, and to provide a long support portion to stably drive each of the lens modules.

[0250] like Figure 17 As shown, the 5-1 guide groove 1013a and 5-2 guide groove 1013b for the first lens module 1210 and the 7-1 guide groove 1014a and 7-2 guide groove 1014b for the second lens module 1220 can be arranged parallel to each other in the bottom surface of the housing 1010, and the first shaft 1215a and the second shaft 1225a can be arranged in the 5-1 guide groove 1013a and the 7-1 guide groove 1014a respectively.

[0251] In the camera module 1000, each of the first lens module 1210 and the second lens module 1220 can move a long distance in the optical axis direction (z-axis direction) to achieve zoom functionality. Therefore, the first axis 1215a, the 5-2nd guide groove 1013b, the second axis 1225a, and the 7-2nd guide groove 1014b can be arranged to overlap each other considerably in a direction perpendicular to the optical axis (z-axis).

[0252] The housing 1010 may include a trough-shaped dust collector DT disposed on its inner surface to collect foreign matter that may be generated therein or may flow into it from the outside, and the dust collector DT may be filled with a sticky adhesive material to easily collect foreign matter.

[0253] A first driving unit 1140 and a second driving unit 1240, respectively used to drive the reflection module 1100 and the lens module 1200, can be disposed in the housing 1010. The first driving unit 1140 has been described in detail above, and the second driving unit 1240 may include a plurality of coils 1241b and 1243b for driving a plurality of lens modules 1200 including the first lens module 1210 and the second lens module 1220.

[0254] As an example, the second drive unit 1240 may include a plurality of magnets 1241a and 1243a, and a plurality of coils 1241b and 1243b arranged to face the plurality of magnets 1241a and 1243a.

[0255] The first lens module 1210 and the second lens module 1220 need to move a long distance in the optical axis direction (z-axis direction) to realize a zoom camera. Therefore, magnets 1241a and 1243a can be magnetized with two or more poles to have at least N pole and S pole in sequence in the optical axis direction (z-axis direction), and coils 1241b and 1243b can include at least two coils 1241b and at least two coils 1243b.

[0256] When electricity is applied to the multiple coils 1241b and 1243b, each of the first lens module 1210 and the second lens module 1220, on which multiple magnets 1241a and 1243a are individually mounted, can move independently in the optical axis direction (z-axis direction) through the electromagnetic force between the multiple magnets 1241a and 1243a and the multiple coils 1241b and 1243b. This enables zoom or autofocus control.

[0257] Multiple magnets 1241a and 1243a can be individually mounted on the first lens module 1210 and the second lens module 1220, respectively. As an example, the first magnet 1241a can be mounted on the side surface of the first lens module 1210, and the second magnet 1243a can be mounted on the side surface of the second lens module 1220.

[0258] Multiple coils 1241b and 1243b can be mounted on housing 1010 to face multiple magnets 1241a and 1243a respectively.

[0259] Since the multiple magnets 1241a and 1243a disposed on the first lens module 1210 and the second lens module 1220 can be arranged separately on the opposite side surfaces of the first lens module 1210 and the second lens module 1220, the multiple coils 1241b and 1243b can also be arranged separately on the opposite side walls of the housing 1010 to face the multiple magnets 1241a and 1243a.

[0260] As an example, multiple coils 1241b and 1243b can be mounted on the motherboard 1070, and the motherboard 1070 can be attached to the outer surface of the housing 1010 such that the multiple coils 1241b and 1243b are exposed to the interior of the housing 1010 through through holes 1010-3 and 1010-4.

[0261] A closed-loop control method can be used. In this method, when the first lens module 1210 and the second lens module 1220 move, their positions can be detected, and feedback related to the detected positions can be provided. For closed-loop control, position detection sensors 1241c and 1243c may be required. Each of the position detection sensors 1241c and 1243c can be a Hall sensor, a TMR angle sensor, a general-purpose TMR sensor, etc.

[0262] Position detection sensors 1241c and 1243c can be arranged inside or outside coils 1241b and 1243b, respectively, and can be mounted on the motherboard 1070 together with coils 1241b and 1243b, respectively. Considering that each of the first lens module 1210 and the second lens module 1220 moves a very long distance, multiple position detection sensors 1241c and multiple position detection sensors 1243c can be arranged to be spaced apart from each other in the optical axis direction (z-axis direction).

[0263] Figure 18A and Figure 18B These are perspective views of various examples of structures in which the lens module or lens barrel, connected to the bracket, is supported by a housing, according to the examples. Figure 19 A perspective view of the shaft and bearing components according to the example is shown.

[0264] refer to Figure 18A The first lens module 1210 or the second lens module 1220 can be guided by the first shaft 1215a or the second shaft 1225a and the third ball member 1215b or the fourth ball member 1225b to move within the housing 1010 in the optical axis direction (z-axis direction). The first bearing member 1218 or the second bearing member 1228 that contacts the first shaft 1215a or the second shaft 1225a can be arranged on the first lens module 1210 or the second lens module 1220.

[0265] For ease of explanation, only the first lens module 1210, the first shaft 1215a, the third ball component 1215b, and the first bearing component 1218 will be described below.

[0266] The first shaft 1215a may be a component fixed to the housing 1010, and the third ball component 1215b may be configured to move in a rolling manner.

[0267] Therefore, when the first lens module 1210 moves in the optical axis direction (z-axis direction), one side of the first lens module 1210 can move on the first axis 1215a, thereby generating sliding friction, and the other side of the first lens module 1210 can move on the third ball member 1215b, thereby generating rolling friction.

[0268] Since one side of the first lens module 1210 moves by sliding on the first axis 1215a, the camera module may also include a first bearing member 1218 to reduce friction and noise.

[0269] In the example, each of the first bearing members 1218 can be a linear bearing. For example, the first bearing member 1218 can have a cylindrical or hemispherical sleeve shape, and a plurality of ball bearings 1218a can be arranged on the inner circumferential surface of the sleeve. The plurality of ball bearings 1218a can be arranged along the optical axis (z-axis). Similarly, the second bearing member 1228 can have a cylindrical or hemispherical sleeve shape, and a plurality of ball bearings 1228a can be arranged on the inner circumferential surface of the sleeve. The plurality of ball bearings 1228a can be arranged along the optical axis (z-axis).

[0270] The first axis 1215a can be arranged to contact the first bearing member 1218. For example, the two first bearing members 1218 can be arranged to be spaced apart from each other in the optical axis direction (z-axis direction) on the lower surface of the first lens module 1210, and each of the two first bearing members 1218 can contact the first axis 1215a.

[0271] The first shaft 1215a is inserted into the 6-1 guide groove 1214a, which can be disposed in the first lens module 1210, and the two first bearing members 1218 can be arranged in the 6-1 guide groove 1214a to be fixed to the first lens module 1210.

[0272] Alternatively, the first bearing component 1218 can be integrally connected to the first lens module 1210 via injection molding. In this case, the first bearing component 1218 can be manufactured as an integral part of the first lens module 1210 by injecting resin material into the mold while the first bearing component 1218 is fixed in the mold.

[0273] Therefore, when the first lens module 1210 moves in the optical axis direction (z-axis direction), the first bearing member 1218 can reduce the friction between the first lens module 1210 and the first shaft 1215a.

[0274] The coating material can be applied to the surface of the first shaft 1215a.

[0275] The coating material can be a solid lubricant mixed with a resin material binder such as polyamide-imide or epoxy resin, and optionally, in addition to lubrication and sliding effects, various types of additives can be added to the coating material to impart wear resistance, rust prevention and other functions.

[0276] The solid lubricant mixed with the binder may be at least one of Teflon, molybdenum (MOS2), polytetrafluoroethylene (PTFE, fluoropolymer) and graphite.

[0277] refer to Figure 18BThe first lens module 1210 may include a lens barrel 1210B having a lens therein and a support 1210H surrounding the lens barrel 1210B. (See reference...) Figure 16 and Figure 17 The description is that all components in the first lens module 1210 can be housed in the bracket 1210H, and the movement of the bracket 1210H can be guided while the bracket 1210H is supported on the housing 1010 by the first shaft 1215a and the third ball member 1215b.

[0278] exist Figure 18B In the example, the first shaft 1215a is inserted into the sixth-first guide groove 1214a, which can be provided in the bracket 1210H, and the first bearing member 1218 can be arranged in the sixth-first guide groove 1214a to be fixed to the bracket 1210H.

[0279] Alternatively, the first bearing component 1218 can be integrally connected to the bracket 1210H via injection molding. In this case, the first bearing component 1218 can be manufactured as an integral part of the bracket 1210H by injecting resin material into the mold while the first bearing component 1218 is fixed in the mold.

[0280] The upper and lower sides of the lens barrel 1210B assembled into the bracket 1210H can be configured to be thin to reduce the thickness, and therefore, the reinforcing member 1210M made of a metallic material (e.g., a non-magnetic metal) can be configured on the bracket 1210H in a shape surrounding the lens barrel 1210B to increase rigidity.

[0281] The reinforcing member 1210M can be provided individually or integrally to surround the upper and lower sides of the lens barrel 1210B. The reinforcing member 1210M can be attached to the lens barrel 1210B using adhesives or the like, or it can be integrally provided with the lens barrel 1210B by insertion injection.

[0282] In this document, the first lens module 1210 is described as an integrally arranged structure for most of the structural description. However, as referenced... Figure 18B As described, the first lens module 1210 may include a lens barrel 1210B having a lens therein and a support 1210H surrounding the lens barrel 1210B.

[0283] Figure 20 This is a perspective view illustrating an example of a structure for supporting a lens module or lens barrel connected to a bracket on a housing, according to another example. Figure 21 A perspective view of a shaft and bearing assembly based on another example is shown.

[0284] refer to Figure 20 and Figure 21Each of the first bearing components 1218 may be an oilless bearing having a cylindrical sleeve shape.

[0285] The first shaft 1215a can be assembled into the first bearing component 1218.

[0286] The first lens module 1210 may have a guide hole 1214c into which a first shaft 1215a is inserted, and a first bearing member 1218 may be disposed in the guide hole 1214c to be fixed to the first lens module 1210. For example, two first bearing members 1218 may be fixed in the guide hole 1214c while being spaced apart from each other in the optical axis direction (z-axis direction), and each of the two first bearing members 1218 may contact the first shaft 1215a. Similarly, the second lens module 1220 may have a guide hole 1224c into which a second shaft 1225a is inserted, and a second bearing member 1228 may be disposed in the guide hole 1224c to be fixed to the second lens module 1220.

[0287] Alternatively, the first bearing component 1218 can be integrally connected to the first lens module 1210 via injection molding. In this case, the first bearing component 1218 can be manufactured as an integral part of the first lens module 1210 by injecting resin material into the mold while the first bearing component 1218 is fixed in the mold.

[0288] Therefore, when the first lens module 1210 moves in the optical axis direction (z-axis direction), the friction between the first lens module 1210 and the first axis 1215a can be reduced.

[0289] Figure 22 This is a perspective view showing a structure for supporting a lens module on a housing, according to another example.

[0290] In the above example, the first lens module 1210 can move along the first axis 1215a in the optical axis direction (z-axis direction), and the second lens module 1220 can move along the second axis 1225a in the optical axis direction (z-axis direction). Conversely, in Figure 22 In the example shown, the first lens module 1210 and the second lens module 1220 can both move along an axis 1235 in the optical axis direction (z-axis direction).

[0291] For example, one side of the first lens module 1210 and one side of the second lens module 1220 can both be supported by a shaft 1235, the other side of the first lens module 1210 can be supported by a third ball member 1215b, and the other side of the second lens module 1220 can be supported by a fourth ball member 1225b.

[0292] Therefore, sliding friction can occur on one side of the first lens module 1210, and rolling friction can occur on the other side of the first lens module 1210. Furthermore, sliding friction can occur on one side of the second lens module 1220, and rolling friction can occur on the other side of the second lens module 1220.

[0293] One side of the first lens module 1210 can contact the shaft 1235 at one point, and one side of the second lens module 1220 can contact the shaft 1235 at two points.

[0294] The other side of the first lens module 1210 can contact two third ball members 1215b, and the other side of the second lens module 1220 can contact a fourth ball member 1225b.

[0295] Therefore, each of the first lens module 1210 and the second lens module 1220 has a three-point support structure.

[0296] The bearing components of the contact shaft 1235 can be arranged on the first lens module 1210 and the second lens module 1220. For example, the first bearing component 1218 can be arranged on one side of the first lens module 1210, and the second bearing component 1228 can be arranged on one side of the second lens module 1220.

[0297] The number of first bearing members 1218 may differ from the number of second bearing members 1228. For example, one first bearing member 1218 may be arranged on one side of the first lens module 1210, and two second bearing members 1228 may be arranged on one side of the second lens module 1220 to be spaced apart from each other in the optical axis direction (z-axis direction).

[0298] The other side of the first lens module 1210 (the side opposite to the optical axis (z-axis)) can be supported by two third spherical members 1215b spaced apart from each other in the optical axis direction (z-axis direction), and the other side of the second lens module 1220 can be supported by a fourth spherical member 1225b.

[0299] The sixth-1 guide groove 1214a into which the shaft 1235 is inserted can be provided in the lower surface of the first lens module 1210 facing the shaft 1235, and the sixth-2 guide groove 1214b in which the third ball member 1215b is arranged can be provided in the lower surface of the first lens module 1210 facing the third ball member 1215b.

[0300] A first bearing member 1218 can be fixedly arranged in the 6-1 guide groove 1214a. Since the two third ball members 1215b are arranged to be spaced apart from each other in the optical axis direction (z-axis direction) on the other side of the first lens module 1210, the two 6-2 guide grooves 1214b can be arranged in the lower surface of the first lens module 1210 to be spaced apart from each other in the optical axis direction (z-axis direction).

[0301] The 8-1 guide groove 1224a into which the shaft 1235 is inserted can be provided in the lower surface of the second lens module 1220 facing the shaft 1235, and the 8-2 guide groove 1224b in which the fourth ball member 1225b is arranged can be provided in the lower surface of the second lens module 1220 facing the fourth ball member 1225b.

[0302] Two second bearing members 1228 spaced apart from each other in the optical axis direction (z-axis direction) can be fixedly arranged in the 8-1 guide groove 1224a.

[0303] A fourth ball component 1225b can be arranged in the 8-2 guide groove 1224b so that it can be moved in a rolling manner.

[0304] Other configurations of the first bearing member 1218 and the second bearing member 1228 may be the same as those in the example described above, and therefore, a detailed description thereof will not be repeated.

[0305] For further reference Figures 26 to 33 The damper and stop of the lens module of the rotating bracket installed according to the example are disclosed.

[0306] refer to Figure 26 The reflection module 1100 and the lens module 1200 can be arranged in the space separated by the first protruding wall 1009.

[0307] For example, the reflection module 1100 can be arranged in front of the first protruding wall 1009, and the lens module 1200 can be arranged behind the first protruding wall 1009.

[0308] The reflector module 1100 may come into contact with the housing 1010 due to impacts, for example, when the reflector module 1100 rotates for optical image stabilization, and the lens module 1200 may come into contact with the housing 1010, for example, during movement in the optical axis direction to achieve zoom or autofocus functions, or due to external impacts. In such cases, damage or excessive travel makes it difficult to precisely control the position in the optical axis direction.

[0309] Therefore, as described above, the housing 1010 of the camera module may be provided with a damper 1050 that is fitted into an insertion groove 1019 provided in the upper side of the housing 1010 (i.e., the upper side of the first protruding wall 1009).

[0310] The stop member 1060 can be configured to control the movement of the first lens module 1210 and the second lens module 1220 respectively. The stop member 1060 may include a first stop member 1061 that limits the movement distance of the first lens module 1210 and a second stop member 1062 that limits the movement distance of the second lens module 1220.

[0311] A pair of first stop members 1061 can be disposed at both ends of the first shaft 1215a to limit the movement distance of the first lens module 1210, and a pair of second stop members 1062 can be disposed at both ends of the second shaft 1225a to limit the movement distance of the second lens module 1220.

[0312] For example, the first stop 1061 can be arranged to press the two ends of the first shaft 1215a in the y-axis direction, and the second stop 1062 can be arranged to press the two ends of the second shaft 1225a in the y-axis direction.

[0313] The housing 1010 may have a first hook portion 1010d and a second hook portion 1010e, and a first stop 1061 and a second stop 1062 may be fixed to the first hook portion 1010d and the second hook portion 1010e.

[0314] The first stop 1061 and the second stop 1062 may respectively include damping materials 1061c and 1062c on the portions facing the first lens module 1210 and the second lens module 1220 to absorb vibrations when the first lens module 1210 and the second lens module 1220 come into contact with the damping materials 1061c and 1062c.

[0315] The first lens module 1210 and the second lens module 1220 may collide with the cover 1030, and may also move unintentionally in a direction perpendicular to the optical axis due to vibration, external impact, etc.

[0316] Therefore, refer to Figure 28 Multiple third stoppers 1211 and fourth stoppers 1221, made of vibration-absorbing materials, can be arranged on the upper surfaces of the first lens module 1210 and the second lens module 1220 facing the cover 1030. The multiple third stoppers 1211 and fourth stoppers 1221 prevent the first lens module 1210 and the second lens module 1220 from directly contacting the cover 1030, thereby preventing damage to the first lens module 1210 and the second lens module 1220.

[0317] refer to Figure 29B The first stop 1061 and the second stop 1062 may include frames 1061a and 1062a, extension portions 1061b and 1062b, and damping materials 1061c and 1062c. The extension portions 1061b and 1062b extend from the frames 1061a and 1062a in a direction perpendicular to the optical axis (z-axis direction), and the damping materials 1061c and 1062c are respectively disposed on the extension portions 1061b and 1062b.

[0318] Damping materials 1061c and 1062c can be inserted into holes provided in extensions 1061b and 1062b to protrude from both surfaces of extensions 1061b and 1062b, or can be fixedly provided on both surfaces of extensions 1061b and 1062b by using an adhesive.

[0319] Each of frames 1061a and 1062a may be configured as a hook to be engaged with one side end of housing 1010 or the upper portion of protruding wall, and each of extensions 1061b and 1062b and each of damping materials 1061c and 1062c may be clamped between one side of each of the first lens module 1210 and the second lens module 1220 and the side surface or protruding wall of housing 1010.

[0320] Frames 1061a and 1062a can be pressed onto or slidably attached to the side wall or protruding wall of housing 1010 by means of hooks, and can also be fixed by means of adhesive bonding.

[0321] refer to Figures 30 to 33 The stop members 1061 and 1062 can be configured to press the two ends of the shafts 1215a and 1225a.

[0322] That is, stops 1061 and 1062 can be disposed at both ends of shafts 1215a and 1225a to limit the movement distance of the first lens module 1210 and the second lens module 1220 or to absorb the vibration of the first lens module 1210 and the second lens module 1220, and can be fixed to the housing by pressing and mounting from top to bottom and / or by adhesive bonding. Using such fixing force, stops 1061 and 1062 can be used to fix shafts 1215a and 1225a mounted on the bottom of the housing.

[0323] Therefore, the partially cut support portion can be disposed in the end portions of the stops 1061 and 1062 (i.e., the ends of the extension portions 1061b and 1062b) to facilitate contact with the shafts 1215a and 1225a, and the support portion can include an upper support portion 1061d that contacts the upper side of the shafts 1215a and 1225a and a side support portion 1061e that faces the side surfaces of the shafts 1215a and 1225a. Figure 29B ).

[0324] Shafts 1215a and 1225a can be fixed to guide grooves 1013a and 1014a of housing 1010 by using adhesive bonding. This is achieved by applying adhesive (B) to multiple locations around the circumference of shafts 1215a and 1225a. Figure 32 ), or by continuously applying adhesive along the circumference of axes 1215a and 1225a. Figure 33 Shafts 1215a and 1225a can be fixed into guide grooves 1013a and 1014a.

[0325] As illustrated above, based on various examples, the camera module is able to achieve zoom functionality, and even if multiple lens modules move in the optical axis direction to achieve zoom functionality, the optical axes of the multiple lens modules can remain aligned.
