[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2025-0008289, filed on January 20, 2025, with the Korean Intellectual Property Office, 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] The camera module may have a structure in which the lens is disposed on the upper side of the reflecting member.

[0005] To avoid a reduction in resolution in this type of front-lens camera module, when image stabilization is performed, the rotation center (e.g., yaw axis) of the reflector can be aligned with the optical axis of the lens (hereinafter referred to as the front lens) located on the upper side of the reflector.

[0006] Meanwhile, a pivoting structure can be used to align the yaw axis of the reflector with the optical axis of the front lens, but the pivoting structure may have limitations in correcting minor jitter.

[0046] Throughout the accompanying drawings and detailed embodiments, unless otherwise described, the same reference numerals refer to the same elements. 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

[0047] In the following description, although examples of this disclosure will be described in detail with reference to the accompanying drawings, it should be noted that the examples are not limited thereto.

[0048] The following detailed embodiments are provided to aid the reader in gaining 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 this disclosure. 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 this disclosure. Furthermore, for clarity and brevity, descriptions of features well-known in the art may be omitted.

[0049] 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, apparatuses, and / or systems described herein will become apparent upon understanding this disclosure.

[0050] 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.

[0051] As used herein, the term “and / or” includes any one of the associated listed items and any combination of any two or more items; similarly, “at least one” includes any one of the associated listed items and any combination of any two or more items.

[0052] 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.

[0053] 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.

[0054] 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 the plural form 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.

[0055] Due to manufacturing techniques and / or tolerances, the shapes shown in the accompanying drawings may vary. 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.

[0056] It should be noted that in this document, the term "may" is used relative to examples, such as regarding what an example may include or implement, meaning that there exists at least one example that includes or implements such a feature, but not all examples are limited to this.

[0057] The features of the examples described herein can be combined in various ways that will become apparent upon understanding this disclosure. Furthermore, although the examples described herein have multiple configurations, other configurations that will become apparent upon understanding this disclosure are also possible.

[0058] Throughout this specification, the X direction, Y direction, and Z direction refer to the directions parallel to the X-axis, Y-axis, and Z-axis, respectively, as shown in the accompanying drawings. Furthermore, unless otherwise stated, the X direction is a concept that includes both the +X-axis and -X-axis directions; this also applies to the Y and Z directions.

[0059] Throughout the specification, the phrase "two directions (or axes) that are parallel or perpendicular to each other" also includes cases where the two directions (or axes) are substantially parallel or substantially perpendicular. For example, the phrase "the first axis and the second axis are perpendicular to each other" means that the first axis and the second axis form an angle of 90 degrees or close to 90 degrees.

[0060] One aspect of this disclosure is to provide a camera module that can compensate for even minute shakes.

[0061] Figure 1 This is a perspective view of a camera module according to one or more embodiments of the present disclosure, and Figure 2 This is a perspective view showing the configuration structure of a camera module according to one or more embodiments of the present disclosure.

[0062] The camera module 1000 according to one or more embodiments of this disclosure can be installed on a portable electronic device such as a smartphone.

[0063] Reference Figure 1 The X-axis, Y-axis, and Z-axis directions can correspond to the width, height, and length directions of the camera module 1000, respectively.

[0064] In one or more embodiments of this disclosure, the height direction (Y-axis direction) of the camera module 1000 may correspond to the thickness direction of the portable electronic device on which the camera module 1000 is mounted. Therefore, the length direction (Z-axis direction) of the camera module 1000 may be relatively unconstrained by the space of the portable electronic device.

[0065] Reference Figure 2 The camera module 1000 may include a first lens module 1100, a reflection module 1200, and a second lens module 1300.

[0066] Light reflected from an external object can sequentially pass through the first lens module 1100, the reflection module 1200, and the second lens module 1300, and can eventually reach the image sensor (not shown).

[0067] The first lens module 1100 may include one or more lenses stacked in the direction of the first optical axis OA1. The direction of the first optical axis OA1 may be parallel to the height direction (Y-axis direction) of the camera module 1000.

[0068] The second lens module 1300 may include multiple lenses stacked in the direction of the second optical axis OA2. The direction of the second optical axis OA2 may be parallel to the length direction (Z-axis direction) of the camera module 1000 and perpendicular to the direction of the first optical axis OA1.

[0069] In one or more embodiments of this disclosure, the second lens module 1300 may include the same number of lenses as the first lens module 1100, or a greater number of lenses than the first lens module 1100. As described above, since the longitudinal direction (Z-axis direction) of the camera module 1000 does not affect the thickness of the portable electronic device, the second lens module 1300 can ensure a sufficient number of lenses.

[0070] The reflection module 1200 may include a reflection member 1210 that alters the path of the incident light (see [reference]). Figure 3 For example, the reflecting member 1210 can be configured as a prism or a mirror.

[0071] The reflective member 1210 can change the path of the incident light from the direction of the first optical axis OA1 to the direction of the second optical axis OA2. The reflective surface of the reflective member 1210 can be set at an angle relative to both the direction of the first optical axis OA1 and the direction of the second optical axis OA2, for example, at an angle of approximately 45 degrees (°) relative to the first optical axis OA1 and the second optical axis OA2.

[0072] Reference Figure 2 The camera module 1000 may include a housing 1010 in which a first lens module 1100, a reflection module 1200, and a second lens module 1300 are disposed.

[0073] The housing 1010 may have an internal space, and the reflection module 1200 and the second lens module 1300 may be housed within the internal space of the housing 1010. The first lens module 1100 may be coupled to the housing 1010 to cover the internal space housing the reflection module 1200.

[0074] In addition, the main substrate 1070 can be attached to the side surface of the housing 1010, and the image sensor can be disposed on the other side surface of the housing 1010.

[0075] Meanwhile, the shield 1030 can be attached to the housing 1010. For example, the shield 1030 can be attached to the housing 1010 to cover most of the components disposed in the housing 1010. The shield 1030 can be used to protect the components disposed in the housing 1010.

[0076] The shield 1030 may include an opening 1031. The first lens module 1100 may be exposed to the outside through the opening 1031, and therefore, light reflected from an external object may be incident on the first lens module 1100.

[0077] Figure 3 This is an exploded perspective view of a camera module according to one or more embodiments of the present disclosure.

[0078] Reference Figure 3 The first lens module 1100 may include a first lens barrel 1110 and a first lens support 1130. One or more lenses stacked in the direction of the first optical axis OA1 are installed in the first lens barrel 1110, and the first lens barrel 1110 is installed on the first lens support 1130.

[0079] The first lens barrel 1110 can be configured to pass through the opening 1031, and since the first lens barrel 1110 is equipped with a lens, light reflected from an external object can be incident on the lens.

[0080] The first lens holder 1130 can be configured to cover the open upper part of the housing 1010, which houses the internal space of the reflection module 1200. The first lens barrel 1110 can be mounted on the first lens holder 1130 so that the reflection module 1200 is aligned with the optical axis (first optical axis OA1).

[0081] The first lens bracket 1130 can be connected to the housing 1010. Therefore, the first lens module 1100 can be a fixed component.

[0082] Meanwhile, the light-blocking member 1150 can be disposed below the first lens bracket 1130. The light-blocking member 1150 can block unwanted light from entering the reflection module 1200 through the first lens module 1100.

[0083] The light-blocking member 1150 may include an opening in the direction of the first optical axis OA1 to allow incident light to pass through, and a peripheral portion that is blackened by an attached film, coating, etc. For example, the light-blocking member 1150 may be formed of plastic or metal.

[0084] A camera module 1000 according to one or more embodiments of this disclosure may have optical image stabilization. For example, the camera module 1000 may correct for shake by rotating (tilting) a reflection module 1200. The reflection module 1200 may rotate about a first axis (X-axis) and a second axis (Y-axis) perpendicular to the first axis (X-axis). The first axis (X-axis) may be perpendicular to both the first optical axis OA1 and the second optical axis OA2, and the second axis (Y-axis) may be an axis parallel to the first optical axis OA1.

[0085] The first axis (X-axis) and the second axis (Y-axis) can intersect each other. For example, the first axis (X-axis) and the second axis (Y-axis) can intersect at the center of the reflective surface of the reflective member 1210.

[0086] Figure 4A , Figure 4B , Figure 5A and Figure 5B This is an exploded perspective view of a reflection module according to one or more embodiments of the present disclosure. Figure 6 This is an exploded perspective view of a reflective bracket according to one or more embodiments of the present disclosure, and Figure 8 This is a perspective view showing a reflective bracket supported on a rotating bearing according to one or more embodiments of the present disclosure.

[0087] Reference Figure 3 The reflection module 1200 may include a reflection bracket 1220 in which a reflection member 1210 is disposed and a rotating bearing portion 1230 in which the reflection bracket 1220 is disposed.

[0088] The reflector bracket 1220 can rotate about a first axis (X-axis) as a rotation axis. The rotation of the reflector bracket 1220 about the first axis (X-axis) can be a relative rotation with respect to the rotating support part 1230. Since the reflector member 1210 is disposed in the reflector bracket 1220, the reflector member 1210 can rotate together with the reflector bracket 1220.

[0089] The rotating support portion 1230 can rotate about a second axis (Y-axis) as a rotation axis. The rotation of the rotating support portion 1230 about the second axis (Y-axis) can be a relative rotation with respect to the housing 1010. Since the reflector bracket 1220 is disposed in the rotating support portion 1230, the reflector bracket 1220 can rotate together with the rotating support portion 1230. Similarly, the reflector member 1210 disposed in the reflector bracket 1220 can also rotate together.

[0090] The first axis (X-axis) and the second axis (Y-axis) can pass through the rotating bearing section 1230.

[0091] The reflection module 1200 may include a first drive unit that provides driving force to the reflection bracket 1220.

[0092] The first driving unit may include a first magnet 1241a disposed in the reflective bracket 1220 and a first coil 1241b disposed in the housing 1010 facing the first magnet 1241a. The first coil 1241b may be disposed in the housing 1010 via the main substrate 1070.

[0093] The reflector bracket 1220 may include an extension 1221 extending from the rear surface of the reflector bracket 1220 between the rotating support portion 1230 and the housing 1010. A first magnet 1241a may be disposed on the extension 1221.

[0094] The first coil 1241b may be disposed on a side surface of the facing extension 1221 of the housing 1010. A first through hole 1011a may be disposed on a side surface of the housing 1010 to expose the first coil 1241b to the interior space of the housing 1010. The first magnet 1241a and the first coil 1241b may face each other directly through the first through hole 1011a.

[0095] The first magnet 1241a and the first coil 1241b can generate a driving force to rotate the reflective bracket 1220 about the first axis (X-axis) as the rotation axis.

[0096] For example, the side of the first magnet 1241a facing the first coil 1241b may include an N pole (or S pole), a neutral region, and an S pole (or N pole) arranged along the rotation direction (Y-axis direction) of the reflector bracket 1220. Therefore, the reflector bracket 1220 can rotate about the first axis (X-axis) as the rotation axis through the electromagnetic interaction between the first magnet 1241a and the first coil 1241b.

[0097] The first position sensor 1241c, which detects and provides feedback on the position of the reflective bracket 1220, can be mounted on the main substrate 1070 together with the first coil 1241b.

[0098] For example, the first position sensor 1241c can be configured as a Hall sensor. The first position sensor 1241c is configured to face the neutral region of the first magnet 1241a, and the position of the reflector 1220 can be detected by detecting the change in magnetic flux driven by the reflector 1220.

[0099] In addition, a drive circuit element (driver IC) that provides a drive signal to the first coil 1241b can be disposed on the main substrate 1070.

[0100] Figure 9A It is along Figure 1 The cross-sectional view taken by line I-I', and Figure 9B and Figure 9CThis is a diagram showing a reflective bracket rotating about a first axis according to one or more embodiments of the present disclosure.

[0101] The reflector bracket 1220 can be mounted on the rotating support portion 1230, and a plurality of ball components (hereinafter referred to as the first ball group) 1251 are inserted between the reflector bracket 1220 and the rotating support portion 1230.

[0102] The first ball assembly 1251 can support the rotation of the reflector bracket 1220 with the first axis (X-axis) as the rotation axis.

[0103] One side of the reflective support 1220 and the rotating support 1230, in which the first ball assembly 1251 is inserted, can be rounded. For example, one side of the reflective support 1220 and the rotating support 1230, in which the first ball assembly 1251 is inserted, can be shaped to correspond to the side surface of a cylinder with a different radius and a central axis that serves as the rotation axis of the reflective support 1220.

[0104] Multiple first guide rails 1223 may be spaced apart on one side of the reflector bracket 1220 in the direction of the first axis (X-axis). Furthermore, multiple second guide rails 1233 may be disposed on one side of the rotating support portion 1230, facing the multiple first guide rails 1223. A first ball assembly 1251 may be disposed between the facing first guide rails 1223 and second guide rails 1233.

[0105] Reference Figure 6 The first ball assembly 1251 may include a first ball member 1251a and a second ball member 1251b with different diameters. For example, the first ball member 1251a may have a larger diameter than the second ball member 1251b.

[0106] The first spherical component 1251a and the second spherical component 1251b can each be provided in multiples. For example, the number of first spherical components 1251a can be greater than the number of second spherical components 1251b.

[0107] The first ball group 1251 may include a subgroup G', which includes one or more first ball members 1251a and second ball members 1251b. The subgroup G' may be arranged spaced apart from each other in the first axis (X-axis) direction and is disposed between the first guide rail 1223 and the second guide rail 1233 facing each other.

[0108] In one or more embodiments of this disclosure, subgroup G' may include two first ball members 1251a and one second ball member 1251b. For example, subgroup G' may include a first ball member 1251a, a second ball member 1251b, and a first ball member 1251a aligned along the length of the first guide rail 1223 and the second guide rail 1233.

[0109] The first ball component 1251a can contact the first guide rail 1223 and the second guide rail 1233 respectively. The first ball component 1251a can roll along the first guide rail 1223 and the second guide rail 1233, while simultaneously contacting the first guide rail 1223 and the second guide rail 1233 respectively.

[0110] The first guide rail 1223 and the second guide rail 1233 can be arc-shaped with the first axis (X-axis) as the center. Therefore, the first ball member 1251a can roll along the arc-shaped trajectory centered on the first axis (X-axis).

[0111] The second ball component 1251b can contact the two first ball components 1251a respectively, and roll together with the first ball components 1251a along an arc-shaped trajectory centered on the first axis (X-axis). In detail, the second ball component 1251b can not contact the first guide rail 1223 and the second guide rail 1233.

[0112] The reflector bracket 1220 can rotate about a first axis (X-axis) along the rolling direction of the first ball member 1251a and the second ball member 1251b.

[0113] According to one or more embodiments of this disclosure, the rotation of the reflector bracket 1220 is supported by the rolling motion of the first ball assembly 1251 located away from the first axis (X-axis), and the occurrence of sliding friction can be significantly reduced.

[0114] When the first ball component 1251a contacts the first guide rail 1223 and the second guide rail 1233 respectively, a gap can be set between the reflective bracket 1220 and the rotating bearing part 1230.

[0115] The first ball assembly 1251 is located between the two opposing sides of the reflective bracket 1220 and the rotating support 1230, which can be separated from each other by the first ball member 1251a, and the rotating support 1230 can rotate without interfering with the rotation of the reflective bracket 1220.

[0116] At the same time, refer to Figure 5A and Figure 5B The first ball group 1251' may include a plurality of first ball members 1251a. For example, the first ball group 1251' may include four first ball members 1251a.

[0117] Four first ball components 1251a can be disposed between the first guide rail 1223 disposed on the reflector bracket 1220 and the second guide rail 1233' disposed on the rotating bearing part 1230.

[0118] In one or more embodiments of this disclosure, the first guide rail 1223 and the second guide rail 1233' may be provided in different numbers. For example, the first guide rail 1223 may face two second guide rails 1233'. For example, the two second guide rails 1233' may be provided spaced apart from each other in the length direction of the first guide rail 1223.

[0119] The intermediate protrusion 1233a can be disposed between the second guide rails 1233' spaced apart along the length direction of the first guide rail 1223, so as to separate the second guide rails 1233' from each other.

[0120] According to one or more embodiments of this disclosure, the first ball member 1251a may be disposed in units of two on the first guide rail 1223, and the first ball member 1251a may be disposed in units of one on each of the second guide rails 1233'. The first ball members 1251a disposed on the first guide rail 1223 may be spaced apart from each other in the length direction of the first guide rail 1223, so as to be disposed on the two second guide rails 1233' facing the first guide rail 1223 respectively. In addition, the first ball members 1251a may be disposed on the second guide rails 1233' while being separated from each other by intermediate protrusions 1233a.

[0121] Figure 10 It is along Figure 1 A cross-sectional view taken from line II-II'.

[0122] The reflector bracket 1220 can be supported on the rotating support portion 1230 in the direction facing the rotating support portion 1230, and the first ball assembly 1251 is inserted between the reflector bracket 1220 and the rotating support portion 1230.

[0123] For this purpose, a pair of magnetic components (hereinafter referred to as the first magnetic component and the second magnetic component) 1261 and 1263 can be respectively disposed on one side of the reflective support 1220 facing each other between the first ball group 1251 and on one side of the rotating bearing part 1230.

[0124] In one or more embodiments of this disclosure, one of the first magnetic member 1261 and the second magnetic member 1263 may be configured as a traction magnet, and the other of the first magnetic member 1261 and the second magnetic member 1263 may be configured as a traction yoke, and the first magnetic member 1261 and the second magnetic member 1263 may be configured to face each other.

[0125] For example, the first magnetic member 1261 disposed in the reflector bracket 1220 may be a traction yoke, and the first magnetic member 1261 may be part of the reinforcing member 1222 inserted into the reflector bracket 1220, which will be described later. The second magnetic member 1263 disposed in the rotating bearing portion 1230 may be a traction magnet, and the second magnetic member 1263 may be magnetized such that the side facing the first magnetic member 1261 has a north pole and a south pole.

[0126] The first magnetic member 1261 and the second magnetic member 1263 can generate an attractive force in the direction they face. The direction in which the first magnetic member 1261 and the second magnetic member 1263 face each other can be a direction that intersects (but is not perpendicular to) both the first axis (X-axis) and the second axis (Y-axis). The first magnetic member 1261 and the second magnetic member 1263 can face each other in an inclined direction relative to both the first axis (X-axis) and the second axis (Y-axis).

[0127] The reflector bracket 1220 can be tightly supported on the rotating support portion 1230 in a direction that intersects (but is not perpendicular to) both the first axis (X-axis) and the second axis (Y-axis) by the attractive force generated between the first magnetic member 1261 and the second magnetic member 1263. Therefore, the first ball assembly 1251 can be held in a state where it is sandwiched between the reflector bracket 1220 and the rotating support portion 1230.

[0128] In one or more embodiments of this disclosure, the reflector bracket 1220 may be supported on the rotating support portion 1230 by a plurality of first ball members 1251a that respectively contact the reflector bracket 1220 and the rotating support portion 1230.

[0129] The first magnetic member 1261 and the second magnetic member 1263 can be disposed within a support region connecting the support points formed by a plurality of first spherical members 1251a. For example, the point of application of the attractive force generated between the first magnetic member 1261 and the second magnetic member 1263 can be located within a support region having a quadrilateral shape.

[0130] Reference Figures 4A to 5B as well as Figure 6 The reflector bracket 1220 may include a reinforcing member 1222 inserted into the reflector bracket 1220. For example, the reinforcing member 1222 may be embedded in the reflector bracket 1220.

[0131] A portion of the reinforcing member 1222 may be exposed to the outside of the reflective support 1220. This exposed portion of the reinforcing member 1222 may face the second magnetic member 1263. For example, a portion of the reinforcing member 1222 may correspond to a first magnetic member 1261 that generates an attractive force with the second magnetic member 1263.

[0132] The reinforcing member 1222 can be used to concentrate the magnetic flux of the first magnet 1241a. In addition, the reinforcing member 1222 can also be used to dissipate the heat generated from the first magnet 1241a.

[0133] Meanwhile, the reflection module 1200 may include an auxiliary member 1270, which is connected to the rotating support portion 1230 to surround a portion of the reflection bracket 1220.

[0134] In one or more embodiments of this disclosure, auxiliary members 1270 may be arranged in a pair, spaced apart from each other on both sides of the reflector bracket 1220 in the direction of the first axis (X-axis). The auxiliary members 1270 may be fitted into connecting grooves 1232 provided in the rotating support portion 1230, while surrounding both sides of the reflector bracket 1220. The auxiliary members 1270 may be positioned at a distance from the reflector bracket 1220 so as not to interfere with the rotation of the reflector bracket 1220 relative to the rotating support portion 1230.

[0135] Figure 7 This is a perspective view of a rotating bearing portion according to one or more embodiments of the present disclosure. Figure 11 This is an exploded perspective view of the rotating bearing portion according to one or more embodiments of the present disclosure, and Figure 12 This is a diagram of the bottom surface of a housing according to one or more embodiments of the present disclosure.

[0136] The reflection module 1200 may include a second drive unit that provides driving force to the rotating bearing 1230.

[0137] The second drive unit may include a second magnet 1243a disposed in the rotating bearing portion 1230 and a second coil 1243b disposed in the housing 1010 facing the second magnet 1243a. The second coil 1243b may be disposed in the housing 1010 via the main substrate 1070.

[0138] The rotating support portion 1230 may include two side surfaces 1231a and 1231b, which have rounded shapes and are spaced apart from each other in the direction of a first axis (X-axis), with the reflective member 1210 located between them. For example, the two side surfaces 1231a and 1231b of the rotating support portion 1230 may have shapes corresponding to portions of the side surfaces of a cylinder having an arbitrary radius and a central axis (Y-axis) (the second axis (Y-axis) is the rotation axis of the rotating support portion 1230).

[0139] In one or more embodiments of this disclosure, the second magnet 1243a may be disposed on one of the two side surfaces 1231a and 1231b of the rotating bearing portion 1230 (the first side surface) 1231a, and the third magnet 1245a may be disposed on the other side surface 1231b of the two side surfaces 1231a and 1231b of the rotating bearing portion 1230 (the second side surface) 1231b.

[0140] The second coil 1243b can be disposed on one side surface of the housing 1010, and this side surface of the housing 1010 faces the side surface 1231a on which the second magnet 1243a is disposed. The side surface of the housing 1010 on which the second coil 1243b is disposed can be a different surface from the side surface of the housing 1010 on which the first coil 1241b is disposed.

[0141] The second through hole 1011b can be provided in a side surface of the housing 1010 where the second coil 1243b is provided, so as to expose the second coil 1243b to the internal space of the housing 1010. The second magnet 1243a and the second coil 1243b can face each other directly through the second through hole 1011b.

[0142] In another embodiment, the second coil 1243b can be disposed on the two side surfaces of the housing 1010 that face the two side surfaces 1231a and 1231b of the rotating bearing portion 1230, and can face the second magnet 1243a and the third magnet 1245a.

[0143] The second magnet 1243a and the second coil 1243b can generate a driving force to make the rotating bearing 1230 rotate about the second axis (Y-axis) as the rotation axis.

[0144] For example, the side of the second magnet 1243a facing the second coil 1243b may include an N pole, a neutral region, and an S pole arranged along the rotation direction (Z-axis direction) of the rotating support portion 1230. (See reference...) Figure 5A and Figure 5B The second magnet 1243a may include an N pole (or S pole), a neutral region, an S pole (or N pole), and another neutral region along the rotation direction (Z-axis direction) of the rotating support portion 1230. Therefore, the rotating support portion 1230 can rotate about the second axis (Y-axis) via the electromagnetic interaction between the second magnet 1243a and the second coil 1243b. Furthermore, the second magnet 1243a can also function as a sensing magnet for sensing the position of the rotating support portion 1230 by having a tripolar polarity.

[0145] The second position sensor 1243c, which detects and provides feedback on the position of the rotating bearing 1230, can be mounted on the main substrate 1070 together with the second coil 1243b.

[0146] For example, the second position sensor 1243c may be equipped with a drive circuit element (driver IC) that includes a Hall sensor function. The second position sensor 1243c is configured to face the neutral region of the second magnet 1243a, and the position of the rotating support 1230 can be detected by detecting changes in magnetic flux based on the drive of the rotating support 1230.

[0147] Figure 13A This is a plan view of a reflection module according to one or more embodiments of the present disclosure, and Figure 13B and Figure 13C This is a diagram showing a rotating bearing portion rotating about a second axis according to one or more embodiments of the present disclosure.

[0148] The rotating bearing portion 1230 may be disposed in the housing 1010, and a plurality of ball members (hereinafter referred to as the second ball group) 1253 are inserted between the rotating bearing portion 1230 and the housing 1010.

[0149] The second ball assembly 1253 can support the rotation of the rotating bearing part 1230 with the second axis (Y-axis) as the rotation axis.

[0150] The bottom surface of the rotating bearing 1230 and the bottom surface of the housing 1010 can face each other, and the second ball assembly 1253 is located between them.

[0151] Multiple first guide grooves 1234 can be disposed on the bottom surface of the rotating bearing portion 1230, and multiple second guide grooves 1014 can be disposed on the bottom surface of the housing 1010, facing the multiple first guide grooves 1234. A second ball assembly 1253 can be disposed between the first guide grooves 1234 and the second guide grooves 1014 facing each other.

[0152] The second ball assembly 1253 may include four ball components 1253a, 1253b, 1253c, and 1253d, which are spaced apart from each other in the circumferential direction of a circle centered on the second axis (Y-axis). For example, two of the four ball components 1253a and 1253b may be disposed on the side surface 1231a of the rotating support portion 1230 where the second magnet 1243a is disposed, and the other two ball components 1253c and 1253d may be disposed on the side surface 1231b of the rotating support portion 1230 where the third magnet 1245a is disposed.

[0153] Four ball components 1253a, 1253b, 1253c, and 1253d can contact the first guide groove 1234 and the second guide groove 1014, respectively. The four ball components 1253a, 1253b, 1253c, and 1253d can roll along the first guide groove 1234 and the second guide groove 1014, while simultaneously contacting the first guide groove 1234 and the second guide groove 1014, respectively.

[0154] For example, the first guide groove 1234 and the second guide groove 1014 can be portions of a circle centered on the second axis (Y-axis) and having an arbitrary radius r. The first guide groove 1234 and the second guide groove 1014 can also be the shape of an arc centered on the second axis (Y-axis). Alternatively, the first guide groove 1234 and the second guide groove 1014 can be the shape of a straight line having a length in the tangential direction of the aforementioned circle. For example, the first guide groove 1234 and the second guide groove 1014 can be the shape extending approximately along the rotation direction of the rotating bearing portion 1230.

[0155] Multiple first guide slots 1234 can be spaced apart from each other in the circumferential direction of a circle with arbitrary radius r centered on the second axis (Y-axis).

[0156] The rotating bearing 1230 can rotate about the second axis (Y-axis) in the direction in which the four ball members 1253a, 1253b, 1253c and 1253d roll.

[0157] According to one or more embodiments of this disclosure, the rotation of the rotating bearing 1230 is supported by the rolling motion of the second ball group 1253 disposed away from the second axis (Y axis), and the occurrence of sliding friction can be significantly reduced.

[0158] Meanwhile, when the four ball components 1253a, 1253b, 1253c and 1253d contact the first guide groove 1234 and the second guide groove 1014 respectively, a gap can be provided between the rotating bearing part 1230 and the housing 1010.

[0159] The bottom surfaces of the rotating bearing portion 1230 and the housing 1010, which face each other and are located between the second ball group 1253, can be separated from each other by four ball members 1253a, 1253b, 1253c and 1253d, and the housing 1010 can rotate without interfering with the rotation of the rotating bearing portion 1230.

[0160] Figure 14 It is along Figure 1 The cross-sectional view taken from line III-III'.

[0161] The rotating bearing portion 1230 can be supported on the housing 1010 in the direction facing the housing 1010, and the second ball assembly 1253 is located between the rotating bearing portion 1230 and the housing 1010.

[0162] The rotating bearing portion 1230 can face the housing 1010 in the second axis (Y-axis) direction, and the second ball group 1253 is located between the rotating bearing portion 1230 and the housing 1010. Magnetic members can be provided in the rotating bearing portion 1230 and the housing 1010 to generate an attractive force in the second axis (Y-axis) direction.

[0163] In one or more embodiments of this disclosure, the rotating support portion 1230 may have a second magnet 1243a and a third magnet 1245a disposed on the side surface of the rotating support portion 1230, and the housing 1010 may have a third magnetic member 1265 disposed at a position facing the second magnet 1243a and the third magnet 1245a respectively in the direction of the second axis (Y axis).

[0164] Reference Figure 14 The second magnet 1243a and the third magnet 1245a can be disposed on two side surfaces 1231a and 1231b of the rotating bearing portion 1230, which are spaced apart from each other in the first axis (X-axis) direction. The third magnetic member 1265 can be disposed as a pair of traction yokes spaced apart from each other in the first axis (X-axis) direction on the bottom surface of the housing 1010, so as to generate an attractive force with the second magnet 1243a and the third magnet 1245a.

[0165] The second magnet 1243a and the third magnet 1245a can be set to be the same magnet.

[0166] In one or more embodiments of this disclosure, the second magnet 1243a and the third magnet 1245a may have an N pole (or S pole), a neutral region, an S pole (or N pole), a neutral region and an N pole (or S pole) along the length direction, and an N pole and an S pole along the width direction. However, in another embodiment, the third magnet 1245a may be a magnet different from the second magnet 1243a.

[0167] The second magnet 1243a and the third magnet 1245a can generate an attractive force in the direction of the second axis (Y-axis) facing the third magnetic member 1265. The rotating support portion 1230 can be supported in close contact with the housing 1010 by the attractive force generated between the rotating support portion 1230 and the housing 1010. Therefore, the second ball assembly 1253 can be held between the rotating support portion 1230 and the housing 1010.

[0168] Meanwhile, within the housing 1010, the yoke 1244 can be positioned facing the second magnet 1243a, and the second coil 1243b is located between the yoke 1244 and the second magnet 1243a. In addition to the third magnetic member 1265, the second magnet 1243a can also generate an attractive force with the yoke 1244.

[0169] The yoke 1244 can be configured to cover the side of the main substrate 1070 opposite to the side of the main substrate 1070 on which the second coil 1243b, etc., is mounted. Therefore, the yoke 1244 can face the second magnet 1243a in the first axis (X-axis) direction, and the second magnet 1243a and the yoke 1244 can generate an attractive force in the first axis (X-axis) direction (which is the direction in which the second magnet 1243a and the yoke 1244 face each other).

[0170] In one or more embodiments of this disclosure, the force F1 generated by the second magnet 1243a and the yoke 1244 in the first axis (X-axis) direction and the force F2 generated by the second magnet 1243a and the third magnetic member 1265 in the second axis (Y-axis) direction can act on a side surface 1231a of the rotating support portion 1230. Therefore, a side surface 1231a of the rotating support portion 1230 can be supported on the housing 1010 in a diagonal direction (which is the direction of the resultant force of the two forces).

[0171] The magnitude of the force acting on a side surface 1231a of the rotating bearing portion 1230 where the second magnet 1243a is provided can be greater than the magnitude of the force acting on a side surface 1231b of the rotating bearing portion 1230 where the third magnet 1245a is provided.

[0172] Therefore, among the four ball members 1253a, 1253b, 1253c and 1253d disposed between the aforementioned rotating bearing portion 1230 and the housing 1010, the two ball members 1253a and 1253b disposed near the second magnet 1243a can be used as main guide members, and the two ball members 1253c and 1253d disposed near the third magnet 1245a can be used as auxiliary guide members.

[0173] Figure 15 This is an exploded perspective view of a lens module according to one or more embodiments of the present disclosure.

[0174] Reference Figure 15 The second lens module 1300 may include a second lens barrel 1310 and a second lens support 1330. Multiple lenses stacked in the direction of the second optical axis OA2 are installed in the second lens barrel 1310, and the second lens barrel 1310 is installed on the second lens support 1330.

[0175] However, in another embodiment, the second lens barrel 1310 can be omitted, and multiple lenses can be directly mounted on the second lens holder 1330.

[0176] In another embodiment, the second lens holder 1330 may be omitted, and multiple second lens barrels 1310 may be provided. One or more lenses may be mounted in multiple second lens barrels 1310, and the multiple second lens barrels 1310 may be arranged along the direction of the second optical axis OA2.

[0177] Refer again Figure 15 The second lens holder 1330 can be accommodated within the interior space of the housing 1010 to be movable in the direction of the second optical axis OA2. Hereinafter, the direction of the second optical axis OA2 can be described as the direction of the third axis (Z-axis). The third axis (Z-axis) can be an axis perpendicular to both the first axis (X-axis) and the second axis (Y-axis).

[0178] The second lens module 1300 may include a lens module drive unit that provides driving force to the second lens holder 1330.

[0179] The lens module driving unit may include a driving magnet 1341a disposed in the second lens holder 1330 and a driving coil 1341b disposed in the housing 1010 facing the driving magnet 1341a. The driving coil 1341b may be disposed in the housing 1010 via the main substrate 1070.

[0180] The driving magnet 1341a can be disposed on one or both side surfaces of the second lens holder 1330. The driving coil 1341b can be disposed on one side surface of the housing 1010, with this side surface of the housing 1010 facing one or both side surfaces of the second lens holder 1330 on which the driving magnet 1341a is disposed. A third through hole 1011c can be disposed in the side surface of the housing 1010 on which the driving coil 1341b is disposed, so as to expose the driving coil 1341b to the internal space of the housing 1010. The driving magnet 1341a and the driving coil 1341b can directly face each other through the third through hole 1011c.

[0181] The driving magnet 1341a and the driving coil 1341b can generate a driving force to move the second lens holder 1330 in the direction of the third axis (Z axis).

[0182] For example, the driving magnet 1341a and the driving coil 1341b may face each other in the first axis (X-axis) direction, and the side of the driving magnet 1341a facing the driving coil 1341b may include an N pole (or S pole), a neutral region, and an S pole (or N pole) arranged along the moving direction (Z-axis) of the second lens holder 1330. Therefore, due to the electromagnetic interaction between the driving magnet 1341a and the driving coil 1341b, the second lens holder 1330 may move in the third axis (Z-axis) direction.

[0183] A third position sensor 1341c, which detects and provides feedback on the position of the second lens holder 1330, can be mounted on the main substrate 1070 together with the drive coil 1341b.

[0184] For example, the third position sensor 1341c is configured to face the neutral region of the driving magnet 1341a, and the position of the second lens holder 1330 can be detected by detecting the change in magnetic flux driven by the second lens holder 1330.

[0185] In addition, a drive circuit element (driver IC) that provides a drive signal to the drive coil 1341b can be disposed on the main substrate 1070.

[0186] The second lens holder 1330 can be disposed in the housing 1010, and a plurality of ball components (hereinafter referred to as the third ball group) 1355 are inserted between the second lens holder 1330 and the housing 1010.

[0187] The third ball assembly 1355 can support the second lens support 1330 to translate along the third axis (Z-axis).

[0188] The bottom surface of the second lens holder 1330 and the bottom surface of the housing 1010 can face each other, and the third ball group 1355 is located between them.

[0189] Multiple third guide grooves 1336 may be disposed on the bottom surface of the second lens holder 1330, and multiple fourth guide grooves 1016 may be disposed on the bottom surface of the housing 1010 to face the multiple third guide grooves 1336. A third ball assembly 1355 may be disposed between the third guide grooves 1336 and the fourth guide grooves 1016 facing each other.

[0190] The third ball assembly 1355 may include three or more ball components, and may include, for example, three ball components 1355a, 1355b, and 1355c. Of the three ball components 1355a, 1355b, and 1355c, two ball components 1355a and 1355b may be disposed on one side of the second lens holder 1330, and the remaining ball component 1355c may be disposed on the opposite side of the second lens holder 1330 relative to the third axis (Z-axis). For example, of the three ball components 1355a, 1355b, and 1355c, two ball components 1355a and 1355b may be disposed on the side of the second lens holder 1330 where the driving magnet 1341a is located, while the remaining ball component 1355c may be disposed on the opposite side.

[0191] The three ball components 1355a, 1355b, and 1355c can contact the third guide groove 1336 and the fourth guide groove 1016, respectively. The three ball components 1355a, 1355b, and 1355c can roll along the third guide groove 1336 and the fourth guide groove 1016, and simultaneously contact the third guide groove 1336 and the fourth guide groove 1016, respectively.

[0192] For example, the third guide groove 1336 and the fourth guide groove 1016 can be in the form of a straight line with a length parallel to the third axis (Z axis).

[0193] The second lens support 1330 can move in the direction of the third axis (Z-axis) along the rolling direction of the three ball components 1355a, 1355b and 1355c.

[0194] Meanwhile, when the three ball components 1355a, 1355b and 1355c contact the third guide groove 1336 and the fourth guide groove 1016 respectively, a gap can be provided between the second lens bracket 1330 and the housing 1010.

[0195] The bottom surfaces of the second lens support 1330 and the housing 1010, which are located between the third ball group 1355 and face each other, can be spaced apart from each other by three ball members 1355a, 1355b and 1355c, and the housing 1010 can move without interfering with the movement of the second lens support 1330.

[0196] The second lens support 1330 can be supported on the housing 1010 in the direction facing the housing 1010, and the third ball assembly 1355 is located between the second lens support 1330 and the housing 1010.

The fifth magnetic component 1363 can be configured as a traction yoke and disposed in the housing 1010. The traction magnet can be magnetized such that one surface facing the traction yoke has both N poles and S poles.

[0199] The fourth magnetic member 1361 and the fifth magnetic member 1363 can generate an attractive force in the direction of the second axis (Y-axis), which is the direction in which the fourth magnetic member 1361 and the fifth magnetic member 1363 face each other. The second lens holder 1330 can be supported in the direction of the second axis (Y-axis) by the attractive force generated between the fourth magnetic member 1361 and the fifth magnetic member 1363. Therefore, the third ball assembly 1355 can be held in the state of being inserted between the second lens holder 1330 and the housing 1010.

For example, the point of application of the attractive force between the fourth magnetic member 1361 and the fifth magnetic member 1363 may be located within a support region having a triangular shape.

[0201] In one or more embodiments of this disclosure, the fourth magnetic member 1361 may be configured to be biased toward two of the three ball members 1355a and 1355b. The two ball members 1355a and 1355b disposed relatively close to the fourth magnetic member 1361 may serve as main guides.

[0202] The fifth magnetic member 1363 may have a larger area than the fourth magnetic member 1361. Specifically, the fifth magnetic member 1363 may be formed to have an area that covers the range of motion of the fourth magnetic member 1361, such that an attractive force can be continuously applied between the fourth magnetic member 1361 and the fifth magnetic member 1363 while the second lens support 1330 moves relative to the housing 1010 in the direction of the third axis (Z-axis).
