Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2024-0064153, filed on May 16, 2024, with the Korean Intellectual Property Office, and Korean Patent Application No. 10-2024-0174926, filed on November 29, 2024, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

[0003] This disclosure relates to a reflection module and a camera module including a reflection module. Background Technology

[0004] Recently, camera modules that bend the path of light by placing a reflective component in front of the lens module have been adopted in mobile devices.

[0005] Additionally, the camera module can have a shake correction function to compensate for camera shake during image capture, thereby improving resolution. This shake correction function can be achieved through the biaxial rotation of the reflective component.

[0006] In this case, since the reflector is set in a rotatable state, there may be a problem that the reflector tilts to one side when the camera module is off. Utility Model Content

[0007] This summary portion is provided to briefly introduce the selection of concepts, which will be further described in the detailed description portion below. This summary portion is not intended to identify key or essential features of the claimed subject matter, nor is it intended to help determine the scope of the claimed subject matter.

[0008] In one general aspect, the reflective module includes: a housing; a support disposed within the housing and configured to be rotatable relative to the housing; a first magnetic portion disposed on a surface of the support; and a second magnetic portion disposed on a surface of the housing and facing the first magnetic portion, wherein attractive and repulsive forces act between the first and second magnetic portions.

[0009] The gap between the first magnetic part and the second magnetic part can change as the support rotates.

[0010] The bracket can also be configured to rotate about at least two axes as rotation axes, the at least two axes being perpendicular to the direction in which the first magnetic part and the second magnetic part face each other and are perpendicular to each other.

[0011] The location of the attractive force can be closer to the center of rotation of the support than the location of the repulsive force.

[0012] The first magnetic part may include a first magnetic body and a third magnetic body both disposed on the support, and the second magnetic part may include a second magnetic body disposed on the housing, wherein each of the first magnetic body, the second magnetic body and the third magnetic body may be a magnet.

[0013] One surface of the first magnetic body and one surface of the second magnetic body can face each other, and one surface of the third magnetic body and one surface of the second magnetic body can face each other. The one surface of the first magnetic body and one surface of the second magnetic body facing each other can have different polarities, and the one surface of the third magnetic body and one surface of the second magnetic body facing each other can have the same polarity.

[0014] The distance between one surface of the first magnetic body and one surface of the second magnetic body can be smaller than the distance between one surface of the third magnetic body and one surface of the second magnetic body.

[0015] The size of the portion of one surface of the first magnetic body and the portion of one surface of the second magnetic body facing each other can be larger than the size of the portion of one surface of the third magnetic body and the portion of one surface of the second magnetic body facing each other.

[0016] The magnitude of attractive force can be greater than the magnitude of repulsive force.

[0017] The first magnetic part may include a first magnetic body and a third magnetic body both disposed on the support, and the second magnetic part may include a second magnetic body disposed on the housing. The first magnetic body may be a magnetic yoke, and each of the second and third magnetic bodies may be a magnet. An attractive force may act between the first and second magnetic bodies, and a repulsive force may act between the third and second magnetic bodies.

[0018] The first magnetic part may include a first magnetic body disposed on the support, and the second magnetic part may include a second magnetic body disposed on the housing. Each of the first magnetic body and the second magnetic body may be a magnet. A surface of the first magnetic body and a surface of the second magnetic body may face each other, and the number of polarities of a surface of the first magnetic body and the number of polarities of a surface of the second magnetic body facing the surface of the first magnetic body may be different from each other.

[0019] The first portion of one surface of the first magnetic body and the second surface of the second magnetic body facing each other can have opposite polarities, the second portion of one surface of the first magnetic body and the second surface of the second magnetic body facing each other can have the same polarity, and the size of the first portion can be larger than the size of the second portion.

[0020] The reflective module may further include: a third magnetic portion disposed on another surface of the support; and a fourth magnetic portion disposed on another surface of the housing and facing the third magnetic portion, wherein a repulsive force may act between the third magnetic portion and the fourth magnetic portion.

[0021] The directions in which the first and second magnetic parts face each other can be perpendicular to the directions in which the third and fourth magnetic parts face each other.

[0022] The reflective module may also include a first spherical component disposed between the housing and the support.

[0023] The first magnetic portion may include a first magnetic body disposed on the support, the second magnetic portion may include a second magnetic body disposed on the housing, and each of the first and second magnetic bodies may have an annular shape surrounding the first spherical member.

[0024] The first guide groove can be formed in the bracket, the second guide groove can be formed in the housing, and the first ball member can be configured to make three-point contact with the first guide groove and three-point contact with the second guide groove.

[0025] In another general aspect, the camera module includes: a housing; a bracket disposed within the housing and configured to be rotatable relative to the housing; an optical component coupled to the bracket; a support portion disposed within the housing between the housing and the bracket and configured to rotatably support the bracket; a first magnetic portion disposed on the bracket; and a second magnetic portion disposed on the housing and facing the first magnetic portion, wherein a repulsive force acts between the first magnetic portion and the second magnetic portion.

[0026] In addition to the repulsive force acting between the first magnetic part and the second magnetic part, the attractive force can also act between the first magnetic part and the second magnetic part, and the location of the attractive force can be closer to the rotation center of the support than the location of the repulsive force.

[0027] The camera module may further include: a first driver, including a first magnet disposed on a bracket and a first coil facing the first magnet; and a second driver, including a second magnet disposed on a bracket and a second coil facing the second magnet.

[0028] The camera module may also include a first lens module, which is coupled to the bracket and has a first optical axis, wherein the optical components may be reflective components, and a first magnetic portion and a second magnetic portion may face each other in the direction of the first optical axis.

[0029] In another general aspect, the reflective module includes: a housing; a bracket disposed within the housing and configured to be rotatable relative to the housing from an initial position to perform jitter correction; a first magnetic portion disposed on a surface of the bracket; and a second magnetic portion disposed on a surface of the housing and facing the first magnetic portion, wherein the first and second magnetic portions are configured to return the bracket to its initial position after jitter correction is performed.

[0030] Both attractive and repulsive forces can act between the first and second magnetic parts in the direction in which they face each other.

[0031] The support can also be configured to rotate about at least two axes as rotation axes to perform jitter correction, the at least two axes being perpendicular to the direction in which the first magnetic portion and the second magnetic portion face each other and being perpendicular to each other, and the location where the attractive force acts can be closer to the rotation center of the support than the location where the repulsive force acts.

[0032] As the stent rotates away from its initial position during jitter correction, the gap between the first and second magnetic parts can be reduced on one side of the stent's rotation center, thereby increasing the repulsive force on one side of the stent during jitter correction. This increased repulsive force can then be used to return the stent to its initial position after jitter correction is performed.

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

[0058] The following detailed embodiments are provided to help the reader gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein, except for operations that must occur in a specific order, as will become apparent upon understanding the disclosure of this application. Furthermore, for clarity and conciseness, descriptions of features well-known in the art may be omitted.

[0059] The features described herein may be implemented in various forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein are provided merely to illustrate some of the many possible ways in which the methods, apparatuses, and / or systems described herein will become apparent upon understanding the disclosure of this application.

[0060] 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.

[0061] As used herein, the term “and / or” includes any one of the associated listed items and any combination of any two or more items.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] This disclosure relates to a reflection module and a camera module including the reflection module, and the camera module can be installed in a portable electronic device such as a mobile communication terminal, a smartphone, or a tablet PC.

[0066] Figure 1 This is a perspective view of a camera module according to an embodiment of the present disclosure, and Figure 2 yes Figure 1 An exploded stereoscopic view of the camera module.

[0067] Reference Figure 1 and Figure 2 According to embodiments of the present disclosure, the camera module 1 may include a reflection module 300 and a housing 100.

[0068] The reflection module 300 may be disposed within the housing 100 and includes a reflection member 310 having a reflective surface.

[0069] The reflection module 300 can be rotatably configured relative to at least two different axes for jitter correction. For example, the reflection module 300 can rotate about three axes perpendicular to each other. As another example, the reflection module 300 can rotate about two axes perpendicular to each other.

[0070] In an embodiment, camera module 1 may further include a first lens module 210.

[0071] The first lens module 210 includes at least one lens, and the at least one lens has a first optical axis (Y-axis). The first optical axis (Y-axis) can be... Figure 2 It extends vertically. The first optical axis (Y-axis) may pass through the center of at least one lens of the first lens module 210.

[0072] In one embodiment, the first lens module 210 includes at least one lens and a first lens barrel 211. The at least one lens may be disposed in the first lens barrel 211, and the first lens barrel 211 may be connected to the reflection module 300.

[0073] Alternatively, the first lens module 210 may include only one lens, and it is also possible for the at least one lens to be coupled to the reflection module 300.

[0074] The first lens module 210 can be positioned in front of the reflection module 300. Here, "in front" can mean that it is positioned relative to the reflection module 300 along the positive first optical axis (Y-axis) direction (+Y-axis direction). For example, the first lens module 210 can be positioned above the reflection module 300 along the first optical axis (Y-axis) direction.

[0075] The first lens module 210 can be connected to the reflection module 300. For example, the first lens barrel 211 of the first lens module 210 can be connected to the bracket 330 of the reflection module 300.

[0076] The first lens module 210 and the reflection module 300 are disposed in the housing 100.

[0077] In one embodiment, the camera module 1 may further include a second lens module 220. A reflection module 300 is disposed between the first lens module 210 and the second lens module 220. The second lens module 220 includes multiple lenses and has a second optical axis (Z-axis). The multiple lenses are arranged along the second optical axis (Z-axis). The second optical axis (Z-axis) may pass through the center of the multiple lenses of the second lens module 220.

[0078] The first optical axis (Y-axis) of the first lens module 210 and the second optical axis (Z-axis) of the second lens module 220 can be perpendicular to each other.

[0079] The first lens module 210 includes one or more lenses, and the second lens module 220 includes multiple lenses.

[0080] When viewed along the first optical axis (Y-axis), one or more lenses of the first lens module 210 may be circular. When viewed along the second optical axis (Z-axis), at least one lens of the plurality of lenses of the second lens module 220 may be non-circular. For example, a non-circular lens may have different lengths in two directions perpendicular to and perpendicular to each other, both of the second optical axis (Z-axis). In an embodiment, in a non-circular lens, the length in the first axis (X-axis) direction, which is perpendicular to both the first optical axis (Y-axis) and the second optical axis (Z-axis), is longer than the length in the first optical axis (Y-axis) direction.

[0081] The first lens module 210 and the reflection module 300 can be configured to rotate together for jitter correction. The second lens module 220 can move in the direction of the second optical axis (Z-axis) for focus adjustment.

[0082] The camera module 1 may also include an image sensor module (not shown). The image sensor module may be located behind the second lens module 220. When the camera module 1 does not include the second lens module 220, the image sensor module may be located behind the reflection module 300.

[0083] The image sensor module may include a sensor housing, an image sensor, and a printed circuit board, and may also include an infrared blocking filter.

[0084] An infrared blocking filter can be mounted on the sensor housing. The infrared blocking filter blocks light in the infrared region from passing through the second lens module.

[0085] The printed circuit board is connected to the sensor housing, and the image sensor is mounted on the printed circuit board.

[0086] Light passing through the second lens module 220 is received by the image sensor module (e.g., an image sensor).

[0087] The camera module 1 may also include a housing 110. The housing 110 is connected to the housing 100 to cover the upper part of the housing 100. The housing 110 has an opening, and the first lens module 210 may be disposed in the opening.

[0088] At least a portion of the first lens module 210 may be configured to protrude outside the housing 100 and the outer casing 110.

[0089] In this embodiment, the reflection module 300, the first lens module 210, and the second lens module 220 are all disposed in a housing 100, but the first housing in which the reflection module 300 is disposed and the second housing in which each lens module is disposed can be disposed as separate components.

[0090] In this case, the first housing can be regarded as a component of the reflection module 300.

[0091] In this embodiment, the reflective member 310 and the first lens module 210 are described as being connected to the bracket 330, but only one of the reflective member 310 and the first lens module 210 may be connected to the bracket 330. In this case, the reflective member 310 or the first lens module 210 connected to the bracket 330 may be referred to as an optical member.

[0092] Figure 3 It is an exploded perspective view of the reflector module and the housing, and Figure 4 It is observed from different directions. Figure 3 The view.

[0093] in addition, Figure 5 It is a 3D diagram of the reflection module, and Figure 6 It is observed from different directions. Figure 5 The view.

[0094] in addition, Figure 7 This is an exploded 3D view of the reflector module and the housing. Figure 8 yes Figure 7 A bottom view of the reflection module, and Figure 9 yes Figure 7 A plan view of the shell.

[0095] Reference Figures 3 to 9 The reflection module 300 includes a reflection component 310 and a bracket 330.

[0096] The reflecting member 310 has a reflective surface that reflects light passing through the first lens module 210. For example, the reflecting member 310 may be a prism or a mirror.

[0097] When the reflecting member 310 is a prism, the reflecting member 310 can have any shape obtained by dividing a rectangular solid (or cube) in half along a diagonal direction. The prism includes an incident surface on which light is incident, a reflecting surface that reflects light passing through the incident surface, and an exiting surface from which light reflected from the reflecting surface is emitted.

[0098] The reflective member 310 is mounted on the bracket 330. The first lens module 210 may be disposed in front of the reflective member 310. In this embodiment, the first lens module 210 may be mounted on the bracket 330.

[0099] The bracket 330 is rotatably mounted in the housing 100.

[0100] The bracket 330 can rotate about a first axis (X-axis) that is perpendicular to both the first optical axis (Y-axis) and the second optical axis (Z-axis). For example, the bracket 330 can rotate about the first axis (X-axis) relative to the housing 100 as a rotation axis. In this case, the first lens module 210 can rotate together with the bracket 330. The first axis (X-axis) can also be referred to as the first rotation axis.

[0101] The bracket 330 can rotate about the second optical axis (Z-axis) as a rotation axis. For example, the bracket 330 can rotate about the second optical axis (Z-axis) relative to the housing 100. In this case, the first lens module 210 can rotate together with the bracket 330. The second optical axis (Z-axis) can also be referred to as the second rotation axis.

[0102] The bracket 330 can rotate about a first optical axis (Y-axis) as a rotation axis. For example, the bracket 330 can rotate relative to the housing 100 about the first optical axis (Y-axis) as a rotation axis. In this case, the first lens module 210 can also rotate together with the bracket 330. The first optical axis (Y-axis) can also be referred to as the third rotation axis.

[0103] The reflection module 300 may also include a first driver 400. The bracket 330 can be rotated about a first axis (X-axis) via the first driver 400.

[0104] The first actuator 400 includes a first magnet 410 and a first coil 420. The bracket 330 can be rotated relative to the housing 100 about a first axis (X-axis) as a rotation axis by the first actuator 400. Since the first lens module 210 is disposed in the bracket 330, the first lens module 210 can also rotate together with the bracket 330.

[0105] The first magnet 410 can be mounted on the bracket 330. For example, the first magnet 410 can be mounted on the first side surface 331 of the bracket 330. The first side surface 331 of the bracket 330 can be the side surface of the bracket 330 facing the housing 100 in the second optical axis (Z axis) direction.

[0106] The first magnet 410 can be magnetized such that a surface (e.g., the surface facing the first coil 420) has both an N pole and a S pole. In an embodiment, the surface of the first magnet 410 facing the first coil 420 may be provided with an N pole, a neutral region, and an S pole arranged sequentially in the direction of the first optical axis (Y-axis).

[0107] The first coil 420 can be configured to face the first magnet 410. In an embodiment, the first coil 420 can be configured to face the first magnet 410 in the direction of the second optical axis (Z axis).

[0108] The first coil 420 is disposed on the substrate 900, and the substrate 900 is mounted on the housing 100, such that the first magnet 410 and the first coil 420 face each other in the direction of the second optical axis (Z axis).

[0109] The housing 100 may be provided with a through hole penetrating the housing 100 in the direction of the second optical axis (Z axis), and the first coil 420 may be disposed in the through hole to directly face the first magnet 410.

[0110] In the jitter correction, the first magnet 410 is a movable component mounted on the bracket 330 and rotating, and the first coil 420 is a fixed component fixed to the substrate 900.

[0111] When power is applied to the first driver 400, the first driver 400 can generate the driving force required to rotate the bracket 330 about a first axis (X-axis) as a rotation axis. For example, the first driver 400 can generate a driving force in the direction of a first optical axis (Y-axis).

[0112] The reflection module 300 may also include a second driver 500. The bracket 330 can be rotated about a second optical axis (Z-axis) via the second driver 500.

[0113] The second actuator 500 includes a second magnet 510 and a second coil 520. The bracket 330 can be rotated relative to the housing 100 about a second optical axis (Z-axis) as a rotation axis by the second actuator 500. Since the first lens module 210 is disposed in the bracket 330, the first lens module 210 can also rotate together with the bracket 330.

[0114] The second magnet 510 can be mounted on the bracket 330. For example, the second magnet 510 can be mounted on the second side surface 332 of the bracket 330. The second side surface 332 of the bracket 330 can be the side surface of the bracket 330 facing the housing 100 in the first axis (X-axis) direction.

[0115] The second side surface 332 of the bracket 330 can be a plane perpendicular to the first side surface 331 of the bracket 330.

[0116] The second magnet 510 can be magnetized such that a surface (e.g., the surface facing the second coil 520) has both an N pole and a S pole. In an embodiment, the surface of the second magnet 510 facing the second coil 520 may be provided with an N pole, a neutral region, and an S pole arranged sequentially in the direction of the first optical axis (Y-axis).

[0117] The second coil 520 can be configured to face the second magnet 510. In one embodiment, the second coil 520 can be configured to face the second magnet 510 in the direction of the first axis (X-axis).

[0118] The second coil 520 is disposed on the substrate 900, and the substrate 900 is mounted on the housing 100, such that the second magnet 510 and the second coil 520 face each other in the first axis (X-axis) direction.

[0119] The housing 100 is provided with a through hole penetrating the housing 100 in the first axis (X-axis) direction, and the second coil 520 is disposed in the through hole to directly face the second magnet 510.

[0120] When jitter correction is performed, the second magnet 510 is a movable component mounted on the bracket 330 and rotating, and the second coil 520 is a fixed component fixed to the substrate 900.

[0121] When power is applied to the second driver 500, the second driver 500 can generate the driving force required to rotate the bracket 330 about the second optical axis (Z-axis) as a rotation axis. For example, the second driver 500 can generate a driving force in the direction of the first optical axis (Y-axis).

[0122] The reflection module 300 may also include a third driver 600. The bracket 330 can be rotated about a first optical axis (Y-axis) via the third driver 600.

[0123] The third actuator 600 includes a third magnet 610 and a third coil 620. The bracket 330 can be rotated relative to the housing 100 about a first optical axis (Y-axis) as a rotation axis by the third actuator 600. Since the first lens module 210 is disposed in the bracket 330, the first lens module 210 can also rotate together with the bracket 330.

[0124] The third magnet 610 can be mounted on the bracket 330. For example, the third magnet 610 can be mounted on the third side surface 333 of the bracket 330. The third side surface 333 of the bracket 330 can be the side surface of the bracket 330 facing the housing 100 in the first axis (X-axis) direction.

[0125] The third side surface 333 of the bracket 330 may be perpendicular to the first side surface 331 of the bracket 330. In addition, the second side surface 332 and the third side surface 333 of the bracket 330 may be spaced apart from each other in the first axis (X-axis) direction.

[0126] The third magnet 610 can be magnetized such that a surface (e.g., the surface facing the third coil 620) has both an N pole and a S pole. In an embodiment, the surface of the third magnet 610 facing the third coil 620 may be provided with an N pole, a neutral region, and an S pole arranged sequentially in the direction of the second optical axis (Z axis).

[0127] The third coil 620 can be configured to face the third magnet 610. In an embodiment, the third coil 620 can be configured to face the third magnet 610 in the direction of the first axis (X-axis).

[0128] The third coil 620 is disposed on the substrate 900, and the substrate 900 is mounted on the housing 100, such that the third magnet 610 and the third coil 620 face each other in the first axis (X-axis) direction.

[0129] The housing 100 is provided with a through hole penetrating the housing 100 in the first axis (X-axis) direction, and the third coil 620 can be disposed in the through hole to directly face the third magnet 610.

[0130] In the jitter correction, the third magnet 610 is a movable component mounted on the bracket 330 and rotating, and the third coil 620 is a fixed component fixed to the substrate 900.

[0131] When power is applied to the third driver 600, the third driver 600 can generate the driving force required to rotate the bracket 330 about the first optical axis (Y-axis) as a rotation axis. For example, the third driver 600 can generate a driving force in the direction of the second optical axis (Z-axis).

[0132] The support portion can be disposed between the bracket 330 and the housing 100. The support portion can rotatably support the bracket 330.

[0133] In one embodiment, the support portion may be a first ball member B1. The first ball member B1 may be disposed between the bracket 330 and the housing 100 to form the rotation center of the bracket 330.

[0134] The intersection of three mutually perpendicular rotation axes can be formed within the support portion. For example, the rotation center of the bracket 330 can be formed in the first ball member B1.

[0135] The first spherical component B1 can be in the shape of a sphere. For example, the first spherical component B1 can be a single sphere.

[0136] The support 330 can be pivotally supported and rotated by the first ball member B1. For example, the support 330 can rotate freely while supported by the first ball member B1. In an embodiment, the support 330 can rotate about three axes of rotation that are perpendicular to each other.

[0137] The virtual plane obtained by extending the neutral region of the first magnet 410 in the direction of the second optical axis (Z axis) can pass through the first spherical member B1.

[0138] The virtual plane obtained by extending the neutral region of the second magnet 510 in the direction of the first axis (X-axis) can pass through the first spherical member B1.

[0139] The virtual plane obtained by extending the neutral region of the third magnet 610 in the direction of the first axis (X-axis) can pass through the first spherical member B1.

[0140] In one embodiment, the first magnet 410 and the first coil 420 may be spaced apart from the first ball member B1 in the direction of the second optical axis (Z-axis). When the first magnet 410 and the first coil 420 generate a driving force in the direction of the first optical axis (Y-axis), the support 330 may rotate about the rotation axis (e.g., the first axis (X-axis)) formed by the first ball member B1.

[0141] In one embodiment, the second magnet 510 and the second coil 520 may be spaced apart from the first ball member B1 in the direction of the first axis (X-axis). When the second magnet 510 and the second coil 520 generate a driving force in the direction of the first optical axis (Y-axis), the support 330 may rotate about the rotation axis (e.g., the second optical axis (Z-axis)) formed by the first ball member B1.

[0142] In one embodiment, the third magnet 610 and the third coil 620 may be spaced apart from the first ball member B1 in the first axis (X-axis) direction. When the third magnet 610 and the third coil 620 generate a driving force in the second optical axis (Z-axis) direction, the support 330 may rotate about the rotation axis (e.g., the first optical axis (Y-axis)) formed by the first ball member B1.

[0143] Although not shown in the accompanying drawings, the support portion may be configured as a protrusion extending from the housing 100 toward the bracket 330. In this case, the end of the protrusion (e.g., the portion that contacts the bracket 330) may be curved. For example, the end of the protrusion may be hemispherical or spherical in shape. When the support portion is a protrusion extending from the housing 100, a guide groove for receiving the protrusion may be formed in the bracket 330.

[0144] In another embodiment, the support portion may also be configured as a protrusion projecting from the bracket 330 toward the housing 100. In this case, the end of the protrusion (e.g., the portion that contacts the housing 100) may be curved. For example, the end of the protrusion may be hemispherical or spherical. When the support portion is a protrusion projecting from the bracket 330, a guide groove for receiving the protrusion may be formed in the housing 100.

[0145] The first guide groove g1 and the second guide groove g2 can be formed in the opposing surfaces of the bracket 330 and the housing 100 (e.g., the opposing surfaces in the direction of the first optical axis (Y-axis)). For example, the first guide groove g1 can be formed in the bracket 330, and the second guide groove g2 can be formed in the housing 100. The first guide groove g1 and the second guide groove g2 can be opposing each other in the direction of the first optical axis (Y-axis).

[0146] The first ball component B1 can be disposed between the first guide groove g1 and the second guide groove g2 to form the rotation axis of the support 330.

[0147] Each of the first guide groove g1 and the second guide groove g2 can make contact with the first ball component B1 at three points.

[0148] In one embodiment, the housing 100 may include a protrusion 101. The protrusion 101 may protrude from the inner bottom surface of the housing 100 in the direction of a first optical axis (Y-axis). A second guide groove g2 may be formed in the upper surface of the protrusion 101.

[0149] The attraction force can act between the housing 100 and the support 330. For example, a first magnetic portion 710 can be disposed on one of the housing 100 and the support 330, and a second magnetic portion 730 can be disposed on the other of the housing 100 and the support 330.

[0150] In an embodiment, the first magnetic portion 710 may include a first magnetic body 711 disposed on the support 330, and the second magnetic portion 730 may include a second magnetic body 731 disposed on the housing 100.

[0151] The first magnetic body 711 and the second magnetic body 731 can face each other in the direction of the first optical axis (Y axis).

[0152] In one embodiment, the first magnetic body 711 may be disposed on the lower surface of the bracket 330, and the second magnetic body 731 may be disposed on the upper surface of the protrusion 101 of the housing 100.

[0153] The planar shapes of the first magnetic body 711 and the second magnetic body 731 may include curves.

[0154] In one embodiment, the first magnetic body 711 may have a closed curve shape surrounding the first guide groove g1. Additionally, the second magnetic body 731 may have a closed curve shape surrounding the second guide groove g2.

[0155] The attraction can act between the first magnetic body 711 and the second magnetic body 731.

[0156] In an embodiment, each of the first magnetic body 711 and the second magnetic body 731 may be a magnet.

[0157] One surface of the first magnetic body 711 and one surface of the second magnetic body 731 may face each other in the direction of the first optical axis (Y axis), and the polarity of the first magnetic body 711 and the polarity of the second magnetic body 731 may be opposite to each other.

[0158] Figure 10 and Figure 11 This is a partial cutaway 3D view of the reflection module. Figure 12 This is a view illustrating the attractive and repulsive forces acting between the support and the housing according to an embodiment.

[0159] The first magnetic portion 710 further includes a third magnetic body 713. In an embodiment, the first magnetic portion 710 includes a first magnetic body 711 and a third magnetic body 713, and the second magnetic portion 730 includes a second magnetic body 731.

[0160] The first magnetic body 711 can be disposed on the bracket 330, the second magnetic body 731 can be disposed on the housing 100, and the third magnetic body 713 can be disposed on the bracket 330. That is to say, the first magnetic body 711 and the third magnetic body 713 can both be disposed on the bracket 330, and the second magnetic body 731 can be disposed on the housing 100.

[0161] exist Figures 10 to 12 In the embodiment shown, each of the first magnetic body 711, the second magnetic body 731, and the third magnetic body 713 may be a magnet.

[0162] In addition, each of the first magnetic body 711, the second magnetic body 731 and the third magnetic body 713 may have a ring shape.

[0163] One surface of the first magnetic body 711 and one surface of the second magnetic body 731 can be arranged to face each other in the direction of the first optical axis (Y axis), and each of the surfaces of the first magnetic body 711 and the second magnetic body 731 facing each other can have a polarity.

[0164] The polarities of a surface of the first magnetic body 711 and a surface of the second magnetic body 731 facing each other can be opposite. For example, when a surface of the first magnetic body 711 has a first polarity, a surface of the second magnetic body 731 can have a second polarity.

[0165] The first polarity and the second polarity are opposite polarities, and when the first polarity is the N pole, the second polarity can be the S pole.

[0166] Therefore, the attractive force can act between the first magnetic body 711 disposed on the support 330 and the second magnetic body 731 disposed on the housing 100. The attractive force can act in the direction of the first optical axis (Y-axis).

[0167] One surface of the third magnetic body 713 and one surface of the second magnetic body 731 are arranged to face each other in the direction of the first optical axis (Y axis), and the surface of the third magnetic body 713 facing the surface of the second magnetic body 731 may have a polarity.

[0168] The polarity of one surface of the third magnetic body 713 and the polarity of one surface of the second magnetic body 731 can be the same. For example, when one surface of the second magnetic body 731 has a second polarity, one surface of the third magnetic body 713 can also have a second polarity.

[0169] Therefore, the repulsive force can act between the third magnetic body 713 disposed on the support 330 and the second magnetic body 731 disposed on the housing 100. The repulsive force can act in the direction of the first optical axis (Y-axis).

[0170] The location of the attractive force can be closer to the first spherical member B1 (i.e., the intersection of multiple rotation axes) than the location of the repulsive force.

[0171] For example, the first magnetic body 711 can be positioned closer to the first spherical member B1 than the third magnetic body 713.

[0172] Therefore, in the reflection module 300 according to the embodiments of the present disclosure, not only an attractive force but also a repulsive force is generated between the bracket 330 and the housing 100.

[0173] When the distance between the second magnet 731 and the third magnet 713 decreases due to the rotation of the bracket 330 during jitter correction, the repulsive force between the second magnet 731 and the third magnet 713 increases, thereby causing the bracket 330 to return to its initial position without applying power to the reflective module 300.

[0174] Here, the initial position refers to the state in which the support 330 does not rotate around the second optical axis (Z-axis) and the first axis (X-axis), for example, the state in which the first magnetic body 711 (or the third magnetic body 713) and the second magnetic body 731 are parallel to each other.

[0175] In other words, the reflection module 300 according to the embodiments of this disclosure can reduce the power consumption for positioning the bracket 330 by mechanically realizing the centering structure of the bracket 330.

[0176] Therefore, the position of the bracket 330 can be adjusted without separate power consumption when jitter correction is not required (e.g., when no power is supplied to the reflection module 300).

[0177] In this way, both attractive and repulsive forces can be generated between the first magnetic part 710 and the second magnetic part 730.

[0178] Since the first magnetic part 710 is disposed on the bracket 330 and the second magnetic part 730 is disposed on the housing 100, both attractive and repulsive forces can be generated between the bracket 330 and the housing 100.

[0179] In addition, the magnitude of the attractive force between the support 330 and the housing 100 can be greater than the magnitude of the repulsive force between the support 330 and the housing 100.

[0180] Therefore, the first ball component B1 can remain in contact with the bracket 330 and the housing 100.

[0181] The distance d1 between the first magnetic body 711 and the second magnetic body 731 may be different from the distance d2 between the third magnetic body 713 and the second magnetic body 731.

[0182] For example, the distance d1 between one surface of the first magnetic body 711 and one surface of the second magnetic body 731 in the direction of the first optical axis (Y axis) can be smaller than the distance d2 between one surface of the third magnetic body 713 and one surface of the second magnetic body 731 in the direction of the first optical axis (Y axis).

[0183] Therefore, the magnitude of the attractive force acting between the first magnetic body 711 and the second magnetic body 731 can be greater than the magnitude of the repulsive force acting between the third magnetic body 713 and the second magnetic body 731.

[0184] Although it has been described that the first magnetic body 711 and the third magnetic body 713 are disposed on the bracket 330 and the second magnetic body 731 is disposed on the housing 100, in another embodiment, the first magnetic body 711 and the third magnetic body 713 may be disposed on the housing 100 and the second magnetic body 731 may be disposed on the bracket 330.

[0185] Reference Figure 10 The rear yoke by can be disposed between the first magnetic body 711 and the support 330. In an embodiment, the other surface of the first magnetic body 711 (i.e., the surface of the first magnetic body 711 opposite to the surface facing one surface of the second magnetic body 731) can contact the rear yoke by. The rear yoke by can prevent magnetic field leakage of the first magnetic body 711, which is a magnet.

[0186] The rear yoke by can be disposed between the second magnetic body 731 and the housing 100. In an embodiment, the other surface of the second magnetic body 731 (i.e., the surface of the second magnetic body 731 opposite to the surface facing one surface of the first magnetic body 711) can contact the rear yoke by. The rear yoke by can prevent magnetic field leakage of the second magnetic body 731, which is a magnet.

[0187] The rear yoke by can be disposed between the third magnetic body 713 and the support 330. In an embodiment, the other surface of the third magnetic body 713 (i.e., the surface of the third magnetic body 713 opposite to the surface facing one surface of the second magnetic body 731) can contact the rear yoke by. The rear yoke by can prevent magnetic field leakage of the third magnetic body 713, which is a magnet.

[0188] Figure 13 This is a view illustrating the attractive and repulsive forces acting between the support and the housing according to another embodiment.

[0189] Figure 13 The embodiment shown differs in size from the first magnetic body 711 and the third magnetic body 713. Figure 12 The implementation shown is illustrated.

[0190] exist Figure 13 In the embodiment shown, each of the first magnetic body 711, the second magnetic body 731, and the third magnetic body 713 may be a magnet.

[0191] One surface of the first magnetic body 711 and one surface of the second magnetic body 731 are arranged to face each other in the direction of the first optical axis (Y axis), and each of the first magnetic body 711 and the second magnetic body 731 may have a polarity.

[0192] Here, the polarity of one surface of the first magnetic body 711 and the polarity of one surface of the second magnetic body 731 facing the first magnetic body 711 can be opposite to each other. For example, when one surface of the first magnetic body 711 has a first polarity, one surface of the second magnetic body 731 can have a second polarity.

[0193] Here, the first polarity and the second polarity are opposite, and when the first polarity is the N pole, the second polarity can be the S pole. Therefore, an attractive force can act between the first magnetic body 711 disposed on the support 330 and the second magnetic body 731 disposed on the housing 100.

[0194] One surface of the third magnetic body 713 and one surface of the second magnetic body 731 are arranged to face each other in the direction of the first optical axis (Y axis), and one surface of the third magnetic body 713 may have a polarity.

[0195] Here, the polarity of one surface of the third magnetic body 713 and the polarity of one surface of the second magnetic body 731 facing the same surface of the third magnetic body 713 can be the same. For example, when one surface of the second magnetic body 731 has a second polarity, one surface of the third magnetic body 713 can also have a second polarity.

[0196] Therefore, the repulsive force can act between the third magnetic body 713 disposed on the support 330 and the second magnetic body 731 disposed on the housing 100.

[0197] The dimensions of the portions of the first magnetic body 711 and the second magnetic body 731 that face each other may be different from the dimensions of the portions of the third magnetic body 713 and the second magnetic body 731 that face each other.

[0198] For example, the size of the portion of one surface of the first magnetic body 711 and the portion of one surface of the second magnetic body 731 facing each other can be larger than the size of the portion of one surface of the third magnetic body 713 and the portion of one surface of the second magnetic body 731 facing each other.

[0199] In other words, the size of the opposite polarity parts facing each other can be larger than the size of the same polarity parts facing each other.

[0200] The length l1 of the portion of one surface of the first magnetic body 711 and the portion of one surface of the second magnetic body 731 facing each other may be different from the length l2 of the portion of one surface of the third magnetic body 713 and the portion of one surface of the second magnetic body 731 facing each other.

[0201] For example, the length l1 of the portion of one surface of the first magnetic body 711 and the portion of one surface of the second magnetic body 731 facing each other can be greater than the length l2 of the portion of one surface of the third magnetic body 713 and the portion of one surface of the second magnetic body 731 facing each other. Here, lengths l1 and l2 are lengths in a direction perpendicular to the first optical axis (Y-axis).

[0202] Therefore, the magnitude of the attractive force acting between the first magnetic body 711 and the second magnetic body 731 can be greater than the magnitude of the repulsive force acting between the third magnetic body 713 and the second magnetic body 731.

[0203] Figure 14 This is a bottom view of a bracket according to another embodiment, and Figure 15 It includes Figure 14 A partial sectional perspective view of the reflective module of the bracket.

[0204] Reference Figure 14 and Figure 15 ,and Figure 12The implementation shown differs from the one in that it has a structure for generating attractive and repulsive forces between the support 330 and the housing 100.

[0205] exist Figure 14 and Figure 15 In the embodiment shown, the first magnetic body 711 may be a magnetic yoke, and each of the second magnetic body 731 and the third magnetic body 713 may be a magnet.

[0206] One surface of the first magnetic body 711 and one surface of the second magnetic body 731 can be arranged to face each other in the direction of the first optical axis (Y axis), and one surface of the second magnetic body 731 can have a polarity (first polarity or second polarity).

[0207] Therefore, the attractive force can act between the first magnetic body 711 disposed on the support 330 and the second magnetic body 731 disposed on the housing 100.

[0208] One surface of the third magnetic body 713 and one surface of the second magnetic body 731 can be arranged to face each other in the direction of the first optical axis (Y axis), and one surface of the third magnetic body 713 can have a polarity.

[0209] Here, the polarity of one surface of the third magnetic body 713 and the polarity of one surface of the second magnetic body 731 facing the surface of the third magnetic body 713 can be the same. For example, when one surface of the second magnetic body 731 has a first polarity, one surface of the third magnetic body 713 can also have a first polarity. Alternatively, when one surface of the second magnetic body 731 has a second polarity, one surface of the third magnetic body 713 can also have a second polarity.

[0210] Therefore, the repulsive force can act between the third magnetic body 713 disposed on the support 330 and the second magnetic body 731 disposed on the housing 100.

[0211] The distance between a surface of the first magnetic body 711 and a surface of the second magnetic body 731 facing each other may be different from the distance between a surface of the third magnetic body 713 and a surface of the second magnetic body 731 facing each other.

[0212] For example, the distance between a surface of the first magnetic body 711 and a surface of the second magnetic body 731 facing each other in the direction of the first optical axis (Y axis) can be smaller than the distance between a surface of the third magnetic body 713 and a surface of the second magnetic body 731 facing each other in the direction of the first optical axis (Y axis).

[0213] Therefore, the magnitude of the attractive force acting between the first magnetic body 711 and the second magnetic body 731 can be greater than the magnitude of the repulsive force acting between the third magnetic body 713 and the second magnetic body 731.

[0214] Figure 16 This is a view illustrating the attractive and repulsive forces acting between the support and the housing according to another embodiment.

[0215] and Figure 15 Compared to the implementation shown, Figure 16 The embodiments shown differ in size between the first magnetic body 711 and the third magnetic body 713.

[0216] exist Figure 16 In the embodiment shown, the first magnetic body 711 may be a magnetic yoke, and each of the second magnetic body 731 and the third magnetic body 713 may be a magnet.

[0217] The dimensions of the portions of the first magnetic body 711 and the second magnetic body 731 that face each other may be different from the dimensions of the portions of the third magnetic body 713 and the second magnetic body 731 that face each other.

[0218] For example, the size of the portion of one surface of the first magnetic body 711 and the portion of one surface of the second magnetic body 731 facing each other can be larger than the size of the portion of one surface of the third magnetic body 713 and the portion of one surface of the second magnetic body 731 facing each other.

[0219] In other words, the size of the part where the attractive force acts can be larger than the size of the part where the repulsive force acts.

[0220] The length l1 of the portion of one surface of the first magnetic body 711 and the portion of one surface of the second magnetic body 731 facing each other may be different from the length l2 of the portion of one surface of the third magnetic body 713 and the portion of one surface of the second magnetic body 731 facing each other.

[0221] For example, the length l1 of the portion of one surface of the first magnetic body 711 and the portion of one surface of the second magnetic body 731 facing each other can be greater than the length l2 of the portion of one surface of the third magnetic body 713 and the portion of one surface of the second magnetic body 731 facing each other. Here, lengths l1 and l2 are lengths in a direction perpendicular to the first optical axis (Y-axis).

[0222] Therefore, the magnitude of the attractive force acting between the first magnetic body 711 and the second magnetic body 731 can be greater than the magnitude of the repulsive force acting between the third magnetic body 713 and the second magnetic body 731.

[0223] Figure 17This is a view illustrating the attractive and repulsive forces acting between the support and the housing according to another embodiment.

[0224] Reference Figure 17 ,and Figure 12 The implementation shown differs from the one in that it has a structure for generating attractive and repulsive forces between the support 330 and the housing 100.

[0225] The first magnetic portion 710 includes a first magnetic body 711, and the second magnetic portion 730 includes a second magnetic body 731. The first magnetic body 711 may be disposed on the bracket 330, and the second magnetic body 731 may be disposed on the housing 100.

[0226] exist Figure 17 In the embodiment shown, each of the first magnetic body 711 and the second magnetic body 731 may be a magnet.

[0227] One surface of the first magnetic body 711 and one surface of the second magnetic body 731 can be arranged to face each other in the direction of the first optical axis (Y axis).

[0228] The number of polarities of one surface of the first magnetic body 711 and the number of polarities of one surface of the second magnetic body 731 facing the first magnetic body 711 can be different from each other.

[0229] In one embodiment, the first magnetic body 711 may be a polarized magnet, wherein a surface of the first magnetic body 711 facing a surface of the second magnetic body 731 has multiple polarities. That is, multiple polarities including opposite polarities can be formed on a surface of the first magnetic body 711 facing a surface of the second magnetic body 731. The second magnetic body 731 may be a unipolar magnet, wherein a surface of the second magnetic body 731 facing a surface of the first magnetic body 711 has a single polarity.

[0230] For example, a surface of the first magnetic body 711 facing a surface of the second magnetic body 731 is magnetized to have a first polarity and a second polarity, and a surface of the second magnetic body 731 facing a surface of the first magnetic body 711 is magnetized to have a polarity (first polarity or second polarity).

[0231] In one embodiment, a surface of the first magnetic body 711 facing a surface of the second magnetic body 731 has a first polarity in the portion closer to the first spherical member B1 (i.e., the intersection of the plurality of rotation axes) and a second polarity in the portion farther away from the first spherical member B1. Additionally, a surface of the second magnetic body 731 facing a surface of the first magnetic body 711 has a second polarity.

[0232] Therefore, the region where the attraction is generated can be the inner region of the facing portions of one surface of the first magnetic body 711 and one surface of the second magnetic body 731, and the region where the repulsive force is generated can be the outer region of the facing portions of one surface of the first magnetic body 711 and one surface of the second magnetic body 731.

[0233] Despite Figure 17 Not shown, but on one surface of the first magnetic body 711 facing one surface of the second magnetic body 731, the length of the portion having the first polarity in the direction perpendicular to the first optical axis (Y-axis) may be greater than the length of the portion having the second polarity in the direction perpendicular to the first optical axis (Y-axis).

[0234] Furthermore, despite Figure 17 Not shown, but the size of the portion of one surface of the first magnetic body 711 and one surface of the second magnetic body 731 that faces each other and has opposite polarities may be larger than the size of the portion of one surface of the first magnetic body 711 and one surface of the second magnetic body 731 that faces each other and has the same polarity.

[0235] Therefore, the magnitude of the attractive force acting between the first magnetic part 710 and the second magnetic part 730 can be greater than the magnitude of the repulsive force acting between the first magnetic part 710 and the second magnetic part 730.

[0236] When a surface of the first magnetic body 711 facing a surface of the second magnetic body 731 has multiple polarities, the length or dimension of the portion having each polarity can be measured by applying a ferrofluid to one surface of the first magnetic body 711. For example, since a neutral region is formed between the first and second polarities, the ferrofluid will not adhere to the neutral region, but only to the portions having the first and second polarities. Therefore, the length or dimension of the portions having the first and second polarities can be measured by measuring the portions to which the ferrofluid adheres.

[0237] Figure 18 This is a view illustrating the attractive and repulsive forces acting between the support and the housing according to another embodiment.

[0238] Reference Figure 18 ,and Figure 17 The implementation shown differs from the one in that it has a structure for generating attractive and repulsive forces between the support 330 and the housing 100.

[0239] The first magnetic portion 710 includes a first magnetic body 711 and a third magnetic body 713, and the second magnetic portion 730 includes a second magnetic body 731.

[0240] The first magnetic body 711 can be disposed on the bracket 330, the second magnetic body 731 can be disposed on the housing 100, and the third magnetic body 713 can be disposed on the bracket 330. That is to say, the first magnetic body 711 and the third magnetic body 713 can both be disposed on the bracket 330, and the second magnetic body 731 can be disposed on the housing 100.

[0241] The first magnetic body 711 and the third magnetic body 713 may be spaced apart from each other along the second optical axis (Z-axis). In an embodiment, the first magnetic body 711 may be positioned closer to the first spherical member B1 (i.e., the intersection of the plurality of rotation axes) than the third magnetic body 713. Figure 18 In the embodiment shown, the first magnetic body 711 may be a magnetic yoke, and each of the second magnetic body 731 and the third magnetic body 713 may be a magnet.

[0242] One surface of the first magnetic body 711 and one surface of the second magnetic body 731 can be arranged to face each other in the direction of the first optical axis (Y axis), and one surface of the second magnetic body 731 can have a polarity (first polarity or second polarity).

[0243] Therefore, the attractive force can act between the first magnetic body 711 disposed on the support 330 and the second magnetic body 731 disposed on the housing 100.

[0244] One surface of the third magnetic body 713 and one surface of the second magnetic body 731 can be arranged to face each other in the direction of the first optical axis (Y axis).

[0245] The number of polarities on the surface of the third magnetic body 713 facing the surface of the second magnetic body 731 may be different from the number of polarities on the surface of the second magnetic body 731 facing the surface of the third magnetic body 713.

[0246] In an embodiment, the third magnetic body 713 may be a polarized magnet, wherein a surface of the third magnetic body 713 facing a surface of the second magnetic body 731 has multiple polarities. That is, multiple polarities including opposite polarities can be formed on a surface of the third magnetic body 713 facing a surface of the second magnetic body 731. The second magnetic body 731 may be a unipolar magnet, wherein a surface of the second magnetic body 731 facing a surface of the third magnetic body 713 has a single polarity.

[0247] For example, a surface of the third magnetic body 713 facing a surface of the second magnetic body 731 is magnetized to have both a first polarity and a second polarity, and a surface of the second magnetic body 731 facing a surface of the third magnetic body 713 is magnetized to have one polarity (either a first polarity or a second polarity).

[0248] Therefore, both attractive and repulsive forces act between the third magnetic body 713 and the second magnetic body 731.

[0249] In one embodiment, the surface of the third magnetic body 713 facing one surface of the second magnetic body 731 has a first polarity in the portion closer to the first spherical member B1 (i.e., the intersection of the plurality of rotation axes) (i.e., the portion closer to the first magnetic body 711), and a second polarity in the portion farther away from the first spherical member B1 (i.e., the portion farther away from the first magnetic body 711). Additionally, the surface of the second magnetic body 731 facing one surface of the third magnetic body 713 has a second polarity.

[0250] Therefore, the region in which an attractive force is generated can be the inner region of the portion of one surface of the third magnetic body 713 and one surface of the second magnetic body 731 facing each other, and the region in which a repulsive force is generated can be the outer region of the portion of one surface of the third magnetic body 713 and one surface of the second magnetic body 731 facing each other.

[0251] Despite Figure 18 Not shown in the figure, but in the embodiment, the distance between a surface of the first magnetic body 711 and a surface of the second magnetic body 731 facing each other may be different from the distance between a surface of the third magnetic body 713 and a surface of the second magnetic body 731 facing each other.

[0252] For example, the distance between a surface of the first magnetic body 711 and a surface of the second magnetic body 731 facing each other in the direction of the first optical axis (Y axis) can be smaller than the distance between a surface of the third magnetic body 713 and a surface of the second magnetic body 731 facing each other in the direction of the first optical axis (Y axis).

[0253] Therefore, the magnitude of the attractive force acting between the support 330 and the housing 100 can be greater than the magnitude of the repulsive force acting between the support 330 and the housing 100.

[0254] In an embodiment, the sum of the length of the surface of the first magnetic body 711 facing one surface of the second magnetic body 731 in a direction perpendicular to the first optical axis (Y-axis) and the length of the portion of the third magnetic body 713 with first polarity on the surface of the second magnetic body 731 facing one surface in a direction perpendicular to the first optical axis (Y-axis) can be greater than the length of the portion of the third magnetic body 713 with second polarity on the surface of the second magnetic body 731 facing one surface in a direction perpendicular to the first optical axis (Y-axis).

[0255] In an embodiment, the sum of the size of the surface of the first magnetic body 711 facing one surface of the second magnetic body 731 and the size of the portion of the third magnetic body 713 having a first polarity facing one surface of the second magnetic body 731 can be greater than the size of the portion of the third magnetic body 713 having a second polarity facing one surface of the second magnetic body 731.

[0256] Figure 19 This is a view illustrating the attractive and repulsive forces acting between the support and the housing according to another embodiment.

[0257] Reference Figure 19 The first magnetic portion 710 includes a first magnetic body 711 and a third magnetic body 713, and the second magnetic portion 730 includes a second magnetic body 731 and a fourth magnetic body 733.

[0258] The first magnetic body 711 can be disposed on the support 330, the second magnetic body 731 can be disposed on the housing 100, the third magnetic body 713 can be disposed on the support 330, and the fourth magnetic body 733 can be disposed on the housing 100. That is, each of the first magnetic body 711 and the third magnetic body 713 can be disposed on the support 330, and each of the second magnetic body 731 and the fourth magnetic body 733 can be disposed on the housing 100.

[0259] The first magnetic body 711 can be positioned closer to the first spherical member B1 (i.e., the intersection of multiple rotation axes) than the third magnetic body 713. Additionally, the second magnetic body 731 can be positioned closer to the first spherical member B1 than the fourth magnetic body 733.

[0260] exist Figure 19 In the embodiments shown, each of the first magnetic body 711, the second magnetic body 731, the third magnetic body 713, and the fourth magnetic body 733 may be a magnet.

[0261] One surface of the first magnetic body 711 and one surface of the second magnetic body 731 are arranged to face each other in the direction of the first optical axis (Y axis), and each of the surfaces of the first magnetic body 711 and the second magnetic body 731 facing each other can have a polarity.

[0262] Here, the polarity of one surface of the first magnetic body 711 and the polarity of one surface of the second magnetic body 731 facing the first magnetic body 711 can be opposite to each other. For example, when the surface of the first magnetic body 711 facing the second magnetic body 731 has a first polarity, the surface of the second magnetic body 731 facing the first magnetic body 711 can have a second polarity.

[0263] The first polarity and the second polarity are opposite polarities, and when the first polarity is the N pole, the second polarity can be the S pole.

[0264] Therefore, the attractive force can act between the first magnetic body 711 disposed on the support 330 and the second magnetic body 731 disposed on the housing 100.

[0265] A surface of the third magnetic body 713 and a surface of the fourth magnetic body 733 are arranged to face each other in the direction of the first optical axis (Y axis), and each of the surfaces of the third magnetic body 713 and the fourth magnetic body 733 facing each other can have a polarity.

[0266] Here, the polarity of one surface of the third magnetic body 713 and the polarity of one surface of the fourth magnetic body 733 facing the surface of the third magnetic body 713 can be the same. For example, when one surface of the third magnetic body 713 facing the surface of the fourth magnetic body 733 has a second polarity, the surface of the fourth magnetic body 733 facing the surface of the third magnetic body 713 can also have a second polarity.

[0267] Therefore, the repulsive force can act between the third magnetic body 713 disposed on the support 330 and the fourth magnetic body 733 disposed on the housing 100.

[0268] The distance between a surface of the first magnetic body 711 and a surface of the second magnetic body 731 facing each other may be different from the distance between a surface of the third magnetic body 713 and a surface of the fourth magnetic body 733 facing each other.

[0269] For example, the distance between a surface of the first magnetic body 711 and a surface of the second magnetic body 731 facing each other in the direction of the first optical axis (Y axis) can be less than the distance between a surface of the third magnetic body 713 and a surface of the fourth magnetic body 733 facing each other in the direction of the first optical axis (Y axis).

[0270] Therefore, the magnitude of the attractive force acting between the first magnetic body 711 and the second magnetic body 731 can be greater than the magnitude of the repulsive force acting between the third magnetic body 713 and the fourth magnetic body 733.

[0271] Figure 20 This is a view illustrating the attractive and repulsive forces acting between the support and the housing according to another embodiment.

[0272] and Figure 19 Compared to the implementation shown, Figure 20The embodiments shown differ in the dimensions of the first magnetic body 711, the second magnetic body 731, the third magnetic body 713, and the fourth magnetic body 733.

[0273] The dimensions of a surface of the first magnetic body 711 and a surface of the second magnetic body 731 facing each other may be different from the dimensions of a surface of the third magnetic body 713 and a surface of the fourth magnetic body 733 facing each other.

[0274] For example, the size of a surface of the first magnetic body 711 and the second magnetic body 731 facing each other can be larger than the size of a surface of the third magnetic body 713 and the fourth magnetic body 733 facing each other.

[0275] In other words, the area where surfaces with opposite polarities face each other can be larger than the area where surfaces with the same polarity face each other.

[0276] The length of a surface of the first magnetic body 711 and the second magnetic body 731 facing each other may be different from the length of a surface of the third magnetic body 713 and the fourth magnetic body 733 facing each other.

[0277] For example, the length of one surface of the first magnetic body 711 and one surface of the second magnetic body 731 facing each other can be greater than the length of one surface of the third magnetic body 713 and one surface of the fourth magnetic body 733 facing each other. Here, the length is the length in the direction perpendicular to the first optical axis (Y-axis).

[0278] Therefore, the magnitude of the attractive force acting between the first magnetic body 711 and the second magnetic body 731 can be greater than the magnitude of the repulsive force acting between the third magnetic body 713 and the fourth magnetic body 733.

[0279] Figure 21 This is a bottom view of the bracket according to another embodiment.

[0280] Reference Figure 21 The first magnetic body 711 and the third magnetic body 713 set on the bracket 330 can have different shapes.

[0281] In one embodiment, the first magnetic body 711 may have a closed curve shape that completely surrounds the first guide groove g1, and the third magnetic body 713 may have an open curve shape that partially surrounds the first guide groove g1. That is, the third magnetic body 713 may have a shape in which the closed curve shape surrounding the first guide groove g1 is cut into a plurality of open curve segments that partially surround the first guide groove g1.

[0282] For example, when viewed in the direction of the first optical axis (Y-axis), the first magnetic body 711 may have a closed curve shape that completely surrounds the first guide groove g1, and the third magnetic body 713 may be a combination of multiple magnetic bodies having an open curve segment shape that partially surrounds the first guide groove g1.

[0283] Figure 22 This is a view showing the repulsive force acting on the reflective module.

[0284] Reference Figure 22 The repulsive force can act between the support 330 and the housing 100. For example, the repulsive force can act in the direction of the second optical axis (Z-axis).

[0285] The reflection module 300 includes a third magnetic part 750 and a fourth magnetic part 770.

[0286] The third magnetic portion 750 may include a plurality of fifth magnetic bodies 751, and the plurality of fifth magnetic bodies 751 may be spaced apart from each other. Each of the plurality of fifth magnetic bodies 751 may be a magnet.

[0287] The fourth magnetic portion 770 may include a plurality of sixth magnetic bodies 771, and the plurality of sixth magnetic bodies 771 may be spaced apart from each other. Each of the plurality of sixth magnetic bodies 771 may be a magnet.

[0288] The third magnetic part 750 can be disposed on the bracket 330, and the fourth magnetic part 770 can be disposed on the housing 100. The third magnetic part 750 and the fourth magnetic part 770 can be arranged to face each other.

[0289] like Figure 22 As shown, the plurality of fifth magnetic bodies 751 of the third magnetic portion 750 may be spaced apart from each other in the direction of the first axis (X-axis) and may be disposed on the first side surface 331 of the support 330. The first magnet 410 may be disposed between the plurality of fifth magnetic bodies 751.

[0290] The plurality of sixth magnetic bodies 771 of the fourth magnetic part 770 may be spaced apart from each other in the direction of the first axis (X axis) and may be disposed on the housing 100.

[0291] The plurality of fifth magnetic bodies 751 of the third magnetic part 750 and the plurality of sixth magnetic bodies 771 of the fourth magnetic part 770 can face each other in the direction of the second optical axis (Z axis).

[0292] Furthermore, the surfaces of the plurality of fifth magnetic bodies 751 and the plurality of sixth magnetic bodies 771 facing each other can be configured to have the same polarity.

[0293] Therefore, a repulsive force acts between the third magnetic part 750 and the fourth magnetic part 770.

[0294] Reference Figure 22 Each of the plurality of fifth magnetic bodies 751 may be a polarized magnet, wherein each of its surfaces has both a first polarity and a second polarity. Additionally, each of the plurality of sixth magnetic bodies 771 may be a polarized magnet, wherein each of its surfaces has both a first polarity and a second polarity.

[0295] In another embodiment, each of the plurality of fifth magnetic bodies 751 may be a monopole magnet, wherein each of its surfaces has a polarity. Additionally, each of the plurality of sixth magnetic bodies 771 may also be a monopole magnet, wherein each of its surfaces has a polarity.

[0296] When the bracket 330 rotates around the first optical axis (Y-axis) as a rotation axis during jitter correction, the distance between some of the fifth magnetic bodies 751 of the third magnetic portion 750 located on one side of the first magnet 410 and some of the sixth magnetic bodies 771 of the fourth magnetic portion 770 located on one side of the first magnet 410 decreases, resulting in an increase in the repulsive force between some of the fifth magnetic bodies 751 and some of the sixth magnetic bodies 771, thereby causing the bracket 330 to return to its initial position when no power is applied to the reflective module 300.

[0297] Here, the initial position refers to the state in which the support 330 does not rotate around the first optical axis (Y-axis), for example, the state in which the third magnetic part 750 and the fourth magnetic part 770 are parallel to each other.

[0298] In other words, the reflection module 300 according to the embodiments of this disclosure can reduce the power consumption for positioning the bracket 330 by mechanically realizing the centering structure of the bracket 330.

[0299] Therefore, the position of the bracket 330 can be adjusted without separate power consumption when jitter correction is not required (e.g., when no power is applied to the reflector module 300).

[0300] As mentioned above, Figure 22 An embodiment is shown in which a plurality of fifth magnetic bodies 751 of the third magnetic portion 750 are spaced apart from each other in the direction of the first axis (X-axis) and are disposed on the first side surface 331 of the support 330.

[0301] Alternatively, the plurality of fifth magnetic bodies 751 of the third magnetic portion 750 may also be spaced apart from each other in the direction of the second optical axis (Z-axis) and may be disposed on the second side surface 332 or the third side surface 333 of the support 330 (see Figure 6In this case, the plurality of fifth magnetic bodies 751 of the third magnetic part 750 and the plurality of sixth magnetic bodies 771 of the fourth magnetic part 770 can face each other in the direction of the first axis (X-axis).

[0302] In addition, the second magnet 510 or the third magnet 610 can be disposed among multiple fifth magnets 751.

[0303] The reflection module 300 can detect the position of the bracket 330. For this purpose, multiple position sensors are provided. The multiple position sensors include a first position sensor 430, a second position sensor 530, and a third position sensor 630.

[0304] Reference Figure 5 and Figure 6 The first position sensor 430 can be configured to face the first magnet 410. The second position sensor 530 can be configured to face the second magnet 510. The third position sensor 630 can be configured to face the third magnet 610.

[0305] The first position sensor 430, the second position sensor 530, and the third position sensor 630 can be disposed on the substrate 900.

[0306] When the bracket 330 rotates around the first axis (X-axis) as the rotation axis, the position of the bracket 330 can be detected by the first position sensor 430.

[0307] When the bracket 330 rotates around the second optical axis (Z-axis) as the rotation axis, the position of the bracket 330 can be detected by the second position sensor 530.

[0308] When the bracket 330 rotates around the first optical axis (Y-axis) as the rotation axis, the position of the bracket 330 can be detected by the third position sensor 630.

[0309] Each of the first position sensor 430, the second position sensor 530, and the third position sensor 630 may be a Hall sensor.

[0310] Reference Figure 2 The spacer 212 can be disposed on the lower surface of the first lens module 210 (i.e., the lower surface of the first lens barrel 211 facing the reflecting member 310). The spacer 212 has an entrance hole through which light passes, and the entrance hole can be non-circular. For example, the entrance hole can be elliptical, similar to a racetrack. That is, the inner surface of the spacer 212 forming the entrance hole can include two planes extending parallel to each other and two curved surfaces connecting the two planes to each other.

[0311] The inner surface of the spacer 212 may have a corrugated shape, in which concave and convex shapes are repeated to prevent flare caused by stray light.

[0312] Reference Figure 7 The reflective module 300 and the housing 100 may each include a first stop 340 and a first stop 102. The first stop 340 and the first stop 102 may each protrude from the surfaces of the bracket 330 and the housing 100 that face each other in the direction of the first optical axis (Z axis).

[0313] In one embodiment, the first stop 340 may be disposed on the lower surface of the bracket 330, and the first stop 102 may be disposed on the upper surface of the protrusion 101 of the housing 100.

[0314] The first stop 340 of the bracket 330 and the first stop 102 of the housing 100 can face each other in the direction of the first optical axis (Y axis).

[0315] Therefore, the rotation range of the bracket 330 can be limited by the first stop members 340 and 102, and thus, the first magnetic part 710 disposed on the bracket 330 and the second magnetic part 730 disposed on the housing 100 can be prevented from colliding with each other.

[0316] In addition, when the camera module 1 is subjected to external impact, damage to the bracket 330 can be prevented by allowing the first stop members 340 and 102 to contact each other.

[0317] An elastic buffer member (not shown) can be connected to the first stops 340 and 102. Therefore, it can buffer impacts.

[0318] Although the first stop 340 and the first stop 102 are described as being disposed on the bracket 330 and the housing 100 respectively, the first stop 340 or the first stop 102 may also be formed on only one of the bracket 330 and the housing 100.

[0319] Reference Figure 2 The reflective module 300 may include a second stop 350. The second stop 350 may be coupled to the housing 100 to cover at least a portion of the bracket 330. For example, the second stop 350 may cover at least a portion of the upper surface of the bracket 330.

[0320] The second stop 350 and the bracket 330 may be spaced apart from each other in the direction of the first optical axis (Y-axis). In addition, the second stop 350 and the bracket 330 may be spaced apart from each other in the direction of the first axis (X-axis).

[0321] Therefore, the bracket 330 can be prevented from separating from the housing 100 due to external impacts and other disturbances without hindering the rotation of the bracket 330.

[0322] A resilient buffer member 351 can be connected to the second stop member 350. The buffer member 351 can be disposed on either or both of one surface and the other surface of the second stop member 350. One surface of the second stop member 350 can be the surface facing the housing 110 in the first optical axis (Y-axis) direction, and the other surface of the second stop member 350 can be the surface facing the bracket 330 in the first optical axis (Y-axis) direction.

[0323] Alternatively, the buffer member 351 may also be disposed on the side surface of the second stop member 350. The side surface of the second stop member 350 may be the surface facing the bracket 330 in the direction of the second optical axis (Z axis).

[0324] Figure 23 This is a perspective view showing the second lens module separated from the camera module according to an embodiment of the present disclosure, and Figure 24 yes Figure 23 A bottom-view stereoscopic view of the second lens module.

[0325] Reference Figure 23 The second lens module 220 can be disposed between the reflection module 300 and the image sensor module (not shown).

[0326] The second lens module 220 can be moved in the direction of the second optical axis (Z axis) to adjust the focus.

[0327] In one embodiment, the second lens module 220 includes multiple lenses and a second lens barrel 221. The multiple lenses can be disposed within the second lens barrel 221.

[0328] The camera module 1 may include a fourth driver 800 to move the second lens module 220 in the direction of the second optical axis (Z axis).

[0329] The fourth driver 800 includes a fourth magnet 810 and a fourth coil 820. The fourth magnet 810 and the fourth coil 820 may be arranged to face each other in a direction perpendicular to the second optical axis (Z-axis) (i.e., in the first axis (X-axis) direction).

[0330] A fourth magnet 810 is disposed on the second lens module 220. For example, the fourth magnet 810 may be disposed on a side surface of the second lens module 220.

[0331] In one embodiment, the fourth magnet 810 may include two magnets, and one magnet may be mounted on each of one side surface and the other side surface of the second lens module 220. The one side surface and the other side surface of the second lens module 220 may be spaced apart from each other in the direction of the first axis (X-axis).

[0332] The fourth magnet 810 can be magnetized such that a surface (e.g., the surface facing the fourth coil 820) has both an N pole and a S pole. For example, a surface of the fourth magnet 810 facing the fourth coil 820 can be provided with an N pole, a neutral region, and an S pole arranged sequentially in the direction of the second optical axis (Z axis).

[0333] The fourth coil 820 is configured to face the fourth magnet 810. For example, the fourth coil 820 may be configured to face the fourth magnet 810 in a direction perpendicular to the second optical axis (Z-axis) (i.e., in the direction of the first axis (X-axis)).

[0334] A fourth coil 820 is disposed on a substrate 900, and the substrate 900 is mounted on a housing 100 such that the fourth magnet 810 and the fourth coil 820 face each other in the first axis (X-axis) direction. In an embodiment, the fourth coil 820 may include two coils spaced apart from each other in the first axis (X-axis) direction, each coil facing a corresponding one of the two magnets of the fourth magnet 810.

[0335] The housing 100 may be provided with a through hole penetrating the housing 100, and the fourth coil 820 provided on the substrate 900 may directly face the fourth magnet 810 through the through hole.

[0336] When adjusting the focus, the fourth magnet 810 is a moving member that is mounted on the second lens module 220 and moves together with the second lens module 220 in the direction of the second optical axis (Z axis), and the fourth coil 820 is a fixed member that is fixed to the substrate 900.

[0337] When power is applied to the fourth coil 820, the second lens module 220 can move in the direction of the second optical axis (Z axis) by the electromagnetic force generated between the fourth magnet 810 and the fourth coil 820.

[0338] The second spherical component B2 can be disposed between the second lens module 220 and the housing 100, and the second lens module 220 can be guided by the second spherical component B2 and can move in the direction of the second optical axis (Z axis). The second spherical component B2 includes a plurality of spheres.

[0339] A traction magnet 840 is disposed on the lower surface of the second lens module 220, and a traction yoke (not shown) may be disposed on the inner bottom surface of the housing 100. In another embodiment, the traction magnet 840 may be disposed on both the second lens module 220 and the housing 100.

[0340] The traction magnet 840 can be disposed close to one side surface of the second lens module 220. That is, the traction magnet 840 can be disposed closer to one side surface of the second lens module 220 in the first axis (X-axis) direction than the other side surface of the second lens module 220. In addition, the traction magnet 840 can be disposed between one side surface of the second lens module 220 and the second optical axis (Z-axis).

[0341] The traction magnet 840 and the traction yoke can be arranged to face each other in the direction of the first optical axis (Y axis).

[0342] The traction magnet 840 and the traction yoke can generate an attractive force between them. For example, the attractive force acts between the traction magnet 840 and the traction yoke in the direction of the first optical axis (Y-axis).

[0343] The second ball component B2 can be kept in contact with the second lens module 220 and the housing 100 by the attraction between the traction magnet 840 and the traction yoke.

[0344] Some of the spheres in the second spherical component B2 may be disposed near one side surface of the second lens module 220 along the first axis (X-axis), and the remaining spheres in the second spherical component B2 may be disposed near the other side surface of the second lens module 220 along the first axis (X-axis). The number of spheres disposed between one side surface of the second lens module 220 and the second optical axis (Z-axis) may be greater than the number of spheres disposed between the other side surface of the second lens module 220 and the second optical axis (Z-axis).

[0345] In an embodiment, the second spherical component B2 may include at least three spheres. When the second spherical component B2 includes three spheres, two of the three spheres may be disposed between one side surface of the second lens module 220 and the second optical axis (Z-axis), and the remaining one of the three spheres may be disposed between the other side surface of the second lens module 220 and the second optical axis (Z-axis).

[0346] Two spheres positioned between a side surface of the second lens module 220 and the second optical axis (Z-axis) can be spaced apart from each other in the direction of the second optical axis (Z-axis).

[0347] The third guide groove g3 and the fourth guide groove g4 can be formed in at least one of the mutually facing surfaces of the second lens module 220 and the housing 100. For example, the third guide groove g3 can be formed in the lower surface of the second lens module 220 near one side surface of the second lens module 220, and the fourth guide groove g4 can be formed in the lower surface of the second lens module 220 near the other side surface of the second lens module 220.

[0348] The third guide groove g3 and the fourth guide groove g4 can be spaced apart from each other in a direction perpendicular to the second optical axis (Z axis) (e.g., in the direction of the first axis (X axis)).

[0349] The third guide groove g3 and the fourth guide groove g4 extend in a direction parallel to the second optical axis (Z axis).

[0350] Some of the balls in the second ball component B2 are disposed in the third guide groove g3, and the remaining balls in the second ball component B2 are disposed in the fourth guide groove g4.

[0351] The number of contact points between some of the balls in the second ball component B2 and the third guide groove g3 is greater than the number of contact points between the remaining balls in the second ball component B2 and the fourth guide groove g4.

[0352] The third guide groove g3 is positioned closer to one side surface of the second lens module 220 than the fourth guide groove g4, and the fourth guide groove g4 is positioned closer to the other side surface of the second lens module 220 than the third guide groove g3.

[0353] The traction magnet 840 can be configured to be closer to the third guide groove g3 than the fourth guide groove g4.

[0354] In this embodiment, camera module 1 can detect the position of second lens module 220. For this purpose, a fourth position sensor 830 is provided. The fourth position sensor 830 can be located at a position facing the fourth magnet 810 of the fourth driver 800 (e.g., at a position facing the fourth magnet 810 in the first axis (X-axis) direction).

[0355] Therefore, when the second lens module 220 moves in the direction of the second optical axis (Z axis), the position of the second lens module 220 can be detected by the fourth position sensor 830.

[0356] The fourth position sensor 830 can be a Hall sensor.

[0357] The second lens module 220 may also include a light-shielding plate 223. The light-shielding plate 223 may be connected to the second lens module 220.

[0358] One side surface and the other side surface of the second lens module 220 can be formed to extend away from the second lens module 220 in the direction of the second optical axis (Z-axis). A portion of one side surface of the second lens module 220 and a portion of the other side surface of the second lens module 220 can face each other in the direction of the first axis (X-axis). A space can be formed between a portion of one side surface of the second lens module 220 and a portion of the other side surface of the second lens module 220 that face each other in the direction of the first axis (X-axis).

[0359] The light-shielding plate 223 can be disposed in the space between a portion of one side surface of the second lens module 220 and a portion of the other side surface of the second lens module 220, which are facing each other in the first axis (X-axis) direction.

[0360] The light shield 223 prevents undesirable reflections of light passing through the second lens module 220 within the housing 100. Therefore, flare phenomena can be suppressed.

[0361] The camera module 1 may also include a third stop 860. The third stop 860 may be coupled to the housing 100 and may cover at least a portion of the second lens module 220.

[0362] In one embodiment, the third stop 860 may be configured to face the upper surface of the second lens module 220 in the first optical axis (Y-axis) direction. One side and the other side of the third stop 860 may be bent and extended in the first optical axis (Y-axis) direction to face the second lens module 220 in the second optical axis (Z-axis) direction.

[0363] The elastic buffer member 861 can be connected to the third stop member 860. For example, the buffer member 861 can be installed on one side and the other side of the third stop member 860 facing the second lens module 220 in the direction of the second optical axis (Z axis).

[0364] Additionally, the buffer member (not shown) may be mounted on either or both of the surfaces of the third stop 860 and the second lens module 220, which face each other in the first optical axis (Y-axis) direction.
