Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2025-0053171, filed on April 23, 2025, with the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

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

[0004] Camera modules are used in portable electronic devices, including smartphones. In particular, foldable camera modules are equipped with reflective modules that include reflective elements.

[0005] When external magnetic devices, such as vibration motors, are installed in portable electronic devices, including smartphones, the external magnetic field may affect the operation of internal components such as sensors, coils, and magnets, causing magnetic interference problems.

[0006] Magnetic interference issues can lead to problems such as focusing errors in camera modules or reduced image stabilization performance.

[0007] As a result, the installation of external magnetic devices is restricted.

[0008] The above information is presented as background information and is intended to aid in understanding this disclosure. No determination or assertion is made as to whether any of the above content can be used as prior art with respect to this disclosure. Summary of the Invention

[0009] The summary portion of this invention is intended to provide a brief overview of the chosen 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.

[0010] In one general aspect, the reflective module includes: a rotating support portion supported on a housing in a first direction, the rotating support portion being rotatable relative to the housing; a reflective bracket supported on the rotating support portion in a second direction different from the first direction, the reflective bracket being rotatable relative to the rotating support portion; and a reflective member coupled to the reflective bracket.

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

[0048] In the following description, although examples of this disclosure will be described in detail with reference to the accompanying drawings, it should be noted that the examples are not limited thereto.

[0049] The following detailed embodiments are provided to aid the reader in gaining a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein, except for operations that must occur in a specific order, as will become apparent upon understanding this disclosure. Furthermore, for clarity and brevity, descriptions of features well-known in the art may be omitted.

[0050] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein are provided merely to illustrate some of the many possible ways in which the methods, apparatuses, and / or systems described herein will be apparent upon understanding this disclosure.

[0051] 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.

[0052] As used herein, the term “and / or” includes any one of the associated listed items and any combination of any two or more items; similarly, “at least one” includes any one of the associated listed items and any combination of any two or more items.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] Due to manufacturing techniques and / or tolerances, the shapes shown in the accompanying drawings may vary. Therefore, the examples described herein are not limited to the specific shapes shown in the accompanying drawings, but include shape variations that occur during manufacturing.

[0057] It should be noted that in this document, the term "may" is used relative to examples, such as regarding what an example may include or implement, meaning that there exists at least one example that includes or implements such a feature, but not all examples are limited to this.

[0058] The features of the examples described herein can be combined in various ways that will become apparent upon understanding this disclosure. Furthermore, although the examples described herein have multiple configurations, other configurations that will become apparent upon understanding this disclosure are also possible.

[0059] This disclosure relates to a reflective module mounted on a camera module, and the camera module can be mounted on a portable electronic device such as a mobile communication terminal, a smartphone, and a tablet PC.

[0060] Figure 1 This is a perspective view of a camera module 100 according to an embodiment of the present disclosure, and Figure 2 This is an exploded perspective view of a camera module 100 according to an embodiment of the present disclosure.

[0061] Reference Figure 1 and 2 According to embodiments of the present disclosure, the camera module 100 may include at least one lens module and a housing 1100.

[0062] Camera module 100 may include at least one lens module. In one embodiment, the at least one lens module may include a first lens module 2000. In another embodiment, in addition to the first lens module 2000, the at least one lens module may also include a second lens module 4000. Light incident on camera module 100 from an external object may pass through the first lens module 2000 and the second lens module 4000 to be incident on image sensor 5000.

[0063] The first lens module 2000 may have a first optical axis O1, and the second lens module 4000 may have a second optical axis O2.

[0064] The first optical axis O1 and the second optical axis O2 may not be parallel. For example, the first lens module 2000 and the second lens module 4000 may be arranged such that the first optical axis O1 and the second optical axis O2 intersect. The first optical axis O1 and the second optical axis O2 may be approximately perpendicular, but the angle between them is not limited to this.

[0065] Lenses included in at least one of the first lens module 2000 and the second lens module 4000 can be configured to be movable relative to the image sensor 5000. For example, a lens included in the first lens module 2000 can be configured to move along a first optical axis O1. In another embodiment, a lens included in the second lens module 4000 can be configured to move along a second optical axis O2. When the lenses included in each lens module move, optical image stabilization (OIS) or autofocus (AF) functions of the camera module 100 can be performed. For example, the camera module 100 can perform an autofocus function by moving the lens of the second lens module 4000 in the direction of the second optical axis O2.

[0066] A lens included in at least one of the first lens module 2000 and the second lens module 4000 can be fixedly positioned relative to the housing 1100. For example, in the camera module 100, a lens included in the first lens module 2000 can be fixed relative to the housing 1100, and a lens included in the second lens module 4000 can be configured to be movable in the direction of the second optical axis O2.

[0067] In the camera module 100, a reflection module 3000 can be configured to change the direction of light emitted from the first lens module 2000 to a direction parallel to the second optical axis O2. For example, referring to... Figure 2 The reflection module 3000, which alters the path of light, can be positioned between the first lens module 2000 and the second lens module 4000. In other words, the camera module 100 may include the reflection module 3000 positioned along the optical path from the first lens module 2000 to the second lens module 4000.

[0068] The reflective module 3000 can be housed within the interior space of the housing 1100 and can alter the path of light incident on the reflective module 3000. Here, the reflective module 3000 can be understood to include at least some of the following: a reflective member 3100 that alters the path of light, components that support and drive the reflective member 3100, and a housing 1100 that houses these components.

[0069] The reflective member 3100 of the reflective module 3000 can be configured to change the path of light by refracting or reflecting light. For example, the reflective member 3100 of the reflective module 3000 can be a prism or a mirror that changes the light path by refracting or reflecting light.

[0070] The reflective member 3100 can alter the path of light emitted from the first lens module 2000 so that it is guided to the second lens module 4000. For example, the reflective member 3100 can change the path of light incident along the first optical axis O1 to a direction that is approximately parallel to the second optical axis O2.

[0071] The reflective member 3100 can be configured to rotate or move within the housing 1100. The optical path can be appropriately altered depending on the rotation or movement of the reflective member 3100. The camera module 100 can perform optical image stabilization (OIS) by rotating or moving the reflective member 3100.

[0072] The reflective member 3100 can be configured to have multiple rotation axes and be rotatable in different directions. For example, the reflective member 3100 can rotate about a first rotation axis R1 parallel to the first optical axis O1, or the reflective member 3100 can rotate about a second rotation axis R2 perpendicular to both the first optical axis O1 and the second optical axis O2. When the reflective member 3100 rotates about the second rotation axis R2, the reflective surface 3130 of the reflective member 3100 (see...) Figure 5 It can be tilted, thereby changing the path of light to be approximately parallel to the second optical axis O2.

[0073] In the following description, the direction parallel to the first optical axis O1 can be referred to as the "first (Z-axis) direction", the direction parallel to the second optical axis O2 can be referred to as the "second (Y-axis) direction", and the direction perpendicular to both the first optical axis O1 and the second optical axis O2 can be referred to as the "third (X-axis) direction".

[0074] The camera module 100 may include a reflection module 3000 and an image sensor 5000, on which light passing through multiple lens modules is incident. The image sensor 5000 can convert the incident light into image information. The image sensor 5000 may be configured such that its light-collecting surface faces the exiting surface of the second lens module 4000, and can generate an electrical signal corresponding to the light incident from the second lens module 4000.

[0075] The image sensor 5000 can be housed inside the housing 1100 or disposed outside the housing 1100.

[0076] The filter unit 6000 may be disposed in front of the image sensor 5000 to filter at least a portion of the light incident from the lens module. The filter unit 6000 may include a filter capable of blocking light of a specific wavelength.

[0077] The housing 1100 may have an internal space capable of accommodating at least one of the reflective module 3000, a plurality of lens modules, or an image sensor 5000. The housing 1100 may be formed of a material with predetermined rigidity to protect the components housed therein. The housing 1100 may be a box-shaped member with an open top. However, the material and shape of the housing 1100 are not limited thereto.

[0078] The camera module 100 may include a shield 1200 covering the upper part of the housing 1100. The shield 1200 may cover the open upper part of the housing 1100 to protect the components inside the housing 1100 from the influence of the external environment.

[0079] In the camera module 100 according to an embodiment, some of the plurality of lens modules may be disposed outside the housing 1100, while other lens modules may be disposed inside the housing 1100. For example, such as Figure 1 or Figure 2 As shown, the first lens module 2000 can be coupled to the outside of the housing 1100 and disposed on top of the reflection module 3000, while the second lens module 4000 can be disposed inside the housing 1100. In this case, the exit surface of the lens included in the first lens module 2000 can be configured to face the incident surface 3110 of the reflection member 3100 included in the reflection module 3000 (see...). Figure 4 ).

[0080] When some lens modules are disposed outside the housing 1100, the camera module 100 may also include components for the structural or optical stability of the lens modules disposed outside the housing 1100. For example, the camera module 100 may also include a cover 1300 capable of shielding the space between the first lens module 2000 and the housing 1100.

[0081] In the following text, reference will be made to Figures 3 to 11B Detailed description of the reflection module 3000. Figure 3 This is a 3D view of the 3000 reflection module. Figure 4 This is an exploded 3D view of the reflection module 3000. Figure 5 This is an exploded stereoscopic view of the reflective module 3000 as viewed from another direction. Figure 6 It is along Figure 3 A partial sectional view taken from line I-I'. Figure 7 It is along Figure 3 A partial sectional view taken from line II-II'. Figure 8 This is the right-side view of the reflection module 3000. Figure 9 This is the left side view of the reflection module 3000. Figure 10 This is a reference diagram relating to the connection between housing 1100 and circuit board 7000. Figure 11A and Figure 11B This is a reference diagram relating to the positions of the drive coil and the position sensor. (Reference) Figures 3 to 11B The described reflection module 3000 corresponds to the above-mentioned reflection module 3000, therefore, redundant descriptions can be omitted.

[0082] Reference Figure 3 The reflection module 3000 can be housed within the housing 1100 and may include a reflection member 3100 capable of altering the optical path. The reflection member 3100 may include an incident surface 3110 and an exit surface 3120, through which light can enter from the first lens module 2000 via the incident surface 3110 and exit via the exit surface 3120.

[0083] The reflective member 3100 can be configured to move within the housing 1100. For example, the reflective member 3100 can rotate about different axes of rotation.

[0084] The reflection module 3000 may include a reflection member 3100 capable of changing the optical path, a reflection bracket 3200 that flexibly supports the reflection member 3100, and a rotating bearing part 3300.

[0085] The reflective member 3100 can change the path of light by refracting or reflecting incident light.

[0086] The reflecting member 3100 may include an incident surface 3110 on which light is incident, a reflecting surface 3130 on which light is reflected, and an exiting surface 3120 from which reflected light is emitted. For example, light incident on the incident surface 3110 in a first direction may be reflected by the reflecting surface 3130 and emitted in a second direction. Here, the first direction may be approximately parallel to the first optical axis O1 of the first lens module 2000, and the second direction may be approximately parallel to the second optical axis O2 of the second lens module 4000.

[0087] The reflective member 3100 can be disposed on the reflective bracket 3200. The reflective bracket 3200 can support, rotate, or move the reflective member 3100. For example, the reflective bracket 3200 can have a support portion 340 supported by a rotating bearing portion 3300, and can rotate about a second rotation axis R2 passing through the support portion 340. Therefore, the reflective member 3100 disposed on the reflective bracket 3200 can also rotate.

[0088] The reflector module 3000 may further include a rotating support portion 3300 that movably or rotatably supports the reflector bracket 3200. The rotating support portion 3300 may be configured to rotatably support the reflector bracket 3200 and simultaneously rotate or move relative to the housing 1100. For example, the reflector bracket 3200 is rotatably supported on the rotating support portion 3300, and the support portion 340 forms a rotation axis inserted between the reflector bracket 3200 and the rotating support portion 3300. Furthermore, the rotating support portion 3300 may be supported on the housing 1100, and at least one ball member (i.e., a first ball member 3410) is inserted between the rotating support portion 3300 and the housing 1100, and thus the rotating support portion 3300 may rotate relative to the housing 1100 about a first rotation axis R1 formed by the first ball member 3410.

[0089] In the reflection module 3000 according to the embodiment, the first rotation axis R1 and the second rotation axis R2 may be different from each other. For example, the first rotation axis R1 and the second rotation axis R2 may be substantially perpendicular.

[0090] The first rotation axis R1 can pass through the incident surface 3110 and the reflecting surface 3130 of the reflecting member 3100. The second rotation axis R2 can be substantially parallel to the reflecting surface 3130 of the reflecting member 3100. For example, the second rotation axis R2 can be disposed on the reflecting surface 3130 or parallel to the reflecting surface 3130 at a predetermined distance.

[0091] In the reflection module 3000, the first rotation axis R1 and the second rotation axis R2 can be configured to intersect at a single point. Here, the point where the first rotation axis R1 and the second rotation axis R2 intersect can be located on or near the reflective surface 3130 of the reflection member 3100.

[0092] When the incident surface 3110 of the reflective module 3000 is parallel to the upper surface of the housing 1100, the incident surface 3110 of the reflective member 3100 can be approximately perpendicular to the first optical axis O1 of the first lens module 2000, and the exit surface 3120 of the reflective member 3100 can be approximately perpendicular to the second optical axis O2 of the second lens module 4000. In this case, the first rotation axis R1 of the reflective module 3000 can be approximately the same as the first optical axis O1, and the second rotation axis R2 of the reflective module 3000 can be perpendicular to both the first optical axis O1 and the second optical axis O2. Furthermore, similar to the intersection of the first rotation axis R1 and the second rotation axis R2, the intersection of the first optical axis O1 and the second optical axis O2 can be located on the reflective surface 3130 of the reflective member 3100.

[0093] Although the camera module 100 shakes under the action of external force, causing light to be incident in a direction deviating from the first optical axis O1, the reflective member 3100 can be rotated appropriately to change the direction of light travel to be approximately parallel to the second optical axis O2.

[0094] The reflective module 3000 may also include support members that allow the reflective bracket 3200 to be supported by the rotating support portion 3300. For example, the support members may be configured as a pair of magnetic members facing each other and applying a magnetic force, and the reflective bracket 3200 may be supported on the rotating support portion 3300 by the magnetic attraction or repulsion force generated by the pair of magnetic members.

[0095] A pair of magnetic components can be defined as a first magnetic component 3240 and a second magnetic component 3340, and can be independently disposed on the reflective support 3200 and the rotating bearing portion 3300, respectively. For example, as Figure 4 and Figure 5As shown, the first magnetic component 3240 and the second magnetic component 3340 may include a traction yoke disposed on the reflective support 3200 and a traction magnet disposed on the rotating support portion 3300. In this case, the traction magnet and the traction yoke generate a magnetic force that attracts each other, and due to the magnetic force, the reflective support 3200 can be supported on the rotating support portion 3300, and the support portion 340 is inserted between the reflective support 3200 and the rotating support portion 3300.

[0096] However, the configuration of the first magnetic member 3240 and the second magnetic member 3340 is not limited to those described above. For example, the traction magnet and the traction yoke can be respectively disposed on the reflective support 3200 and the rotating bearing 3300. Alternatively, both the first magnetic member 3240 and the second magnetic member 3340 can be configured as magnets.

[0097] The support member is not limited to the magnetic member described above, and may include any material capable of flexibly supporting the reflector bracket 3200 on the rotating bearing portion 3300.

[0098] A sensing magnet can be installed on the reflection module 3000. The first sensing magnet 121 can be installed on the rotating support 3300, and the second sensing magnet 221 can be installed on the reflection bracket 3200.

[0099] The first sensing magnet 121 may be configured to alternately have N poles and S poles in the second direction, and the second sensing magnet 221 may be configured to alternately have N poles and S poles in the first direction.

[0100] The first sensing magnet 121 and the second sensing magnet 221 can be disposed on the reflection module 3000 to face the housing 1100 respectively along a third direction perpendicular to both the first and second directions, thereby improving external magnetic field interference.

[0101] The first sensing magnet 121 and the second sensing magnet 221 can be configured to face the surface of the housing 1100 on an imaginary line extending through the second rotation axis R2.

[0102] The first sensing magnet 121 and the second sensing magnet 221 can be arranged such that a surface of the housing 1100 facing the first sensing magnet 121 in a third-party direction is the same as a surface of the housing 1100 facing the second sensing magnet 221 in a third-party direction.

[0103] Therefore, there is no limitation on setting external magnetic devices on the opposite sides of the portion of the first sensing magnet 121 and the second sensing magnet 221 arranged in a third direction relative to the reflection module 3000, thereby improving external magnetic field interference.

[0104] Similarly, there is no restriction on setting an external magnetic device on the opposite side of the portion of the second lens module 4000 that is set along the second direction relative to the portion of the reflection module 3000, thereby improving external magnetic field interference.

[0105] Although the first sensing magnet 121 and the second sensing magnet 221 are arranged on the same surface of the reflection module 3000, the center of gravity of the reflection module 3000 may remain unchanged.

[0106] The first sensing magnet 121 and the second sensing magnet 221 can be disposed on the reflection module 3000 as a single unit rather than multiple units.

[0107] In an embodiment, the reflection module 3000 may include a driving magnet for driving the reflection bracket 3200 and the rotating support portion 3300. For example, as Figure 3 As shown, the reflection module 3000 may include a first driving magnet 111 that drives the rotating support portion 3300 and a second driving magnet 211 that drives the reflection bracket 3200.

[0108] The first driving magnet 111 and the second driving magnet 211 can respectively face the first driving coil 112 and the second driving coil 212 disposed in the housing 1100, and the rotating support 3300 can rotate through the electromagnetic interaction between the first driving magnet 111 and the first driving coil 112. In addition, the reflective bracket 3200 can rotate through the electromagnetic interaction between the second driving magnet 211 and the second driving coil 212.

[0109] In the camera module 100, the driving magnet and the driving coil can be respectively disposed on components that move relative to each other. For example, the first driving magnet 111 can be disposed on the rotating support 3300, and the first driving coil 112 can be disposed on the housing 1100. The second driving magnet 211 can be disposed on the reflector bracket 3200, and the second driving coil 212 can be disposed on the housing 1100.

[0110] The first driving magnet 111 can be disposed on the rotating support 3300 parallel to the first sensing magnet 121, and the second driving magnet 211 can be disposed on the reflective bracket 3200 parallel to the second sensing magnet 221.

[0111] The first driving magnet 111 can be disposed on the same surface of the rotating bearing portion 3300 on the same surface on which the first sensing magnet 121 is disposed, and the second driving magnet 211 can be disposed on the same surface of the reflective bracket 3200 on the same surface on which the second sensing magnet 221 is disposed.

[0112] The first driving magnet 111 may be disposed on the rotating support portion 3300 adjacent to or spaced apart from the first sensing magnet 121. Similarly, the second driving magnet 211 may be disposed on the reflective bracket 3200 adjacent to or spaced apart from the second sensing magnet 221.

[0113] The positions of the first driving magnet 111 and the first sensing magnet 121 can be interchanged, and similarly, the positions of the second driving magnet 211 and the second sensing magnet 221 can be interchanged.

[0114] The polarity direction of the first driving magnet 111 and the polarity direction of the first sensing magnet 121 can be the same, and similarly, the polarity directions of the second driving magnet 211 and the second sensing magnet 221 can also be the same.

[0115] The size of the first driving magnet 111 can be larger than the size of the first sensing magnet 121, and similarly, the size of the second driving magnet 211 can be larger than the size of the second sensing magnet 221.

[0116] The first driving magnet 111 and the second driving magnet 211 can be arranged on the surface of the reflective module 3000 facing the housing 1100 in a third direction. Therefore, the driving magnets, driving coils, and yokes do not need to be arranged in the second direction and the first direction of the reflective module 3000. Thus, the design difficulty can be reduced and the degree of freedom in arrangement can be increased.

[0117] In addition to being arranged parallel to the first sensing magnet 121 and the second sensing magnet 221 on one surface of the reflection module 3000, multiple driving magnets can also be arranged on another surface of the reflection module 3000 facing the housing 1100 in a third-party direction.

[0118] The housing 1100 may include a position sensor capable of detecting the amount of movement of the sensing magnet. For example, the housing 1100 may include a first position sensor 122 facing the first sensing magnet 121. Similarly, the housing 1100 may include a second position sensor 222 facing the second sensing magnet 221.

[0119] When the incident surface 3110 of the reflective module 3000 is parallel to the upper surface of the housing 1100, each position sensor can be configured to face the neutral region of the sensing magnet. Here, the neutral region of the sensing magnet can refer to the boundary between the two polarities (i.e., the N pole and the S pole).

[0120] The reflection module 3000 may also include a yoke for flux concentration. For example, the yoke may be positioned to face the first drive coil 112, and a first drive magnet 111 may be inserted between the yoke and the first drive coil 112. The yoke may also be positioned to face the first sensing magnet 121.

[0121] However, the configuration of the drive unit of the drive reflection module 3000 is not limited to the above configuration, and can be any configuration that allows the movement of the reflection bracket 3200 and the rotation of the bearing 3300.

[0122] The rotating support 3300 included in the reflection module 3000 will be described in more detail below.

[0123] The reflective module 3000 may include a rotating support portion 3300 rotatable relative to the housing 1100. The rotating support portion 3300 is rotatable relative to the housing 1100 and rotatably supports the reflective bracket 3200 and the reflective member 3100. For example, the rotating support portion 3300 is configured to rotate about a first rotation axis R1, and therefore, the reflective member 3100 can also rotate together with the rotating support portion 3300 about the first rotation axis R1.

[0124] At least one ball member that rotatably supports the rotating bearing portion 3300 may be disposed between the rotating bearing portion 3300 and the housing 1100.

[0125] At least one ball component may include a first ball component 3410 forming a rotation axis of the rotating support portion 3300 and a guide ball component 3420 facilitating stable rotation of the rotating support portion 3300.

[0126] The first ball component 3410 can be rotated in situ to form a first rotation axis R1, while being fixed in place relative to the housing 1100. Therefore, the first rotation axis R1 can pass through the first ball component 3410.

[0127] The first rotation axis R1 can be approximately aligned with the first optical axis O1 of the first lens module 2000 facing the reflection module 3000. Therefore, an imaginary line extending along the first optical axis O1 can pass through the first spherical member 3410.

[0128] The first ball member 3410 can be accommodated in the first receiving recess 1120 of the housing 1100. To ensure the position of the first ball member 3410, the first receiving recess 1120 can be configured to support the first ball member 3410 at at least three points. For example, the first receiving recess 1120 can have at least three inclined surfaces, and the first ball member 3410 can make point contact with each inclined surface and be supported by each inclined surface. Therefore, the first ball member 3410 can be supported by the first receiving recess 1120 at at least three points. In addition, a recess 3321 facing the first receiving recess 1120 and having the same shape can be provided on the rotating support portion 3300. Therefore, the first ball member 3410 can rotate in situ while being clamped between the rotating support portion 3300 and the housing 1100, thereby forming a first rotating shaft R1.

[0129] At least one guide ball component 3420 can be provided. For example, such as Figure 3 and Figure 4 As shown, the reflection module 3000 may include a first ball member 3410 and two guide ball members 3420 spaced apart from each other. The guide ball members 3420 may roll relative to the housing 1100 or the rotating support 3300 and may support the rotation of the rotating support 3300 while maintaining a predetermined distance from the bottom surface of the housing 1100.

[0130] The guide ball member 3420 can be received in a guide recess of the housing 1100. This guide recess is referred to as the first guide recess 1130. The guide ball member 3420 can be supported at one or two points in the first guide recess 1130. The guide ball member 3420 is movable along the first guide recess 1130. The first guide recess 1130 can be configured to extend in the circumferential direction of the first rotation axis R1. Alternatively, the first guide recess 1130 can be configured to extend in the tangential direction based on the circumference of the first rotation axis R1.

[0131] Meanwhile, another guide recess accommodating the guide ball member 3420 can be provided on the lower surface of the rotating support portion 3300. This guide recess is referred to as the second guide recess 2230. When the guide ball member 3420 is supported on the first guide recess 1130 at two points, the guide ball member 3420 can be supported on the second guide recess 2230 at one point, and when the guide ball member 3420 is supported on the first guide recess 1130 at one point, the guide ball member 3420 can be supported on the second guide recess 2230 at two points.

[0132] The guide ball component 3420 can rotate the bearing portion 3300 by rolling support, and is sandwiched between the second guide recess 2230 of the rotating bearing portion 3300 and the first guide recess 1130 of the housing 1100.

[0133] The driving force for rotating the rotating bearing portion 3300 can be generated by the first driving unit 110. For example, the first driving unit 110 may include a first driving magnet 111 and a yoke disposed on the rotating bearing portion 3300, and a first driving coil 112 disposed on the housing 1100. The driving force can be generated by the electromagnetic interaction between the first driving magnet 111 and the first driving coil 112.

[0134] The first driving magnet 111 and the first driving coil 112 can be configured to face each other in a third direction. Here, the third direction can be perpendicular to both the first direction and the second direction.

[0135] The first drive coil 112 can be disposed in the housing 1100. Multiple first drive coils 112 can be disposed to face multiple drive magnets. In addition, the first drive coil 112 can be disposed to face the yoke, and the first drive magnet 111 is inserted between the first drive coil 112 and the yoke.

[0136] The first driving magnet 111 can be configured such that its surface facing the first driving coil 112 has an N pole, a neutral region and an S pole in the rotation direction of the rotating bearing portion 3300.

[0137] The first driving unit 110 may include a magnetic yoke facing the first driving magnet 111. For example, as Figure 3 and Figure 4 As shown, the magnetic yoke can be configured to face the first drive coil 112, and the first drive magnet 111 is inserted between the magnetic yoke and the first drive coil 112.

[0138] The yoke can be configured as a magnetic component. Therefore, the yoke can be used to focus the magnetic field lines generated by the first driving magnet 111.

[0139] The first sensing unit 120 may include a first sensing magnet 121 and a first position sensor 122 for detecting the position of the first sensing magnet 121. For example, the first position sensor 122 may include a Hall sensor as a magnetic sensor. The first position sensor 122 can detect the amount of movement of the first sensing magnet 121 by detecting the change in magnetic flux passing through the first position sensor 122.

[0140] When one surface of the reflective module 3000 is parallel to one surface of the housing 1100 in a third-direction orientation, the first position sensor 122 can be configured to face the neutral region of the first sensing magnet 121. That is, the first position sensor 122 can be configured to face the boundary region between the N pole and the S pole of the first sensing magnet 121 to effectively detect the displacement of the first sensing magnet 121.

[0141] Multiple first position sensors 122 can be arranged, and the signals detected by each first position sensor 122 can be compared with each other to more accurately detect position changes of the first sensing magnet 121.

[0142] Magnetic components can be arranged between the rotating bearing portion 3300 and the housing 1100, and can interact to generate a magnetic attraction. These are defined as third magnetic components 4510 and fourth magnetic components 4520, and the magnetic force generated between them is defined as a first magnetic force.

[0143] The third magnetic component 4510 can be disposed on either the housing 1100 or the rotating bearing portion 3300, and the fourth magnetic component 4520 can be disposed on the other of the housing 1100 and the rotating bearing portion 3300.

[0144] At least one of the third magnetic component 4510 and the fourth magnetic component 4520 can be a traction magnet, and both the third magnetic component 4510 and the fourth magnetic component 4520 can be traction magnets.

[0145] The reflective bracket 3200 included in the reflective module 3000 will be described in detail below.

[0146] The reflective module 3000 may include a reflective bracket 3200 rotatable relative to the rotating support 3300. A reflective member 3100 may be fixed to the reflective bracket 3200 and rotatable relative to the rotating support 3300. For example, the reflective bracket 3200 may be configured to rotate about a second rotation axis R2, and therefore, the reflective member 3100 may also rotate together with the reflective bracket 3200 about the second rotation axis R2.

[0147] The support portion 340 can be disposed between the reflector bracket 3200 and the rotating bearing portion 3300 to guide the rotation of the reflector bracket 3200.

[0148] In an embodiment, the support portion 340 may include a plurality of second ball members 3430. For example, as Figure 3 As shown, a plurality of second ball members 3430 may be provided between the reflector bracket 3200 and the rotating bearing portion 3300 to form a second rotation axis R2, which is the rotation axis of the reflector bracket 3200.

[0149] The support portion 340 may include a plurality of second ball members 3430, which may be arranged to be spaced apart from each other in a direction perpendicular to the first rotation axis R1.

[0150] The support portion 340 may include a plurality of second ball members 3430, which may be spaced apart from each other in a direction perpendicular to both the first optical axis O1 of the first lens module 2000 and the second optical axis O2 of the second lens module 4000.

[0151] The support portion 340 may include a plurality of second ball members 3430, which can rotate in situ while being fixed in place relative to the reflective bracket 3200 or the rotating bearing portion 3300, thereby forming a second rotation axis R2. The second rotation axis R2 may pass through the support portion 340.

[0152] In another embodiment, the support portion 340 may include a support protrusion 3440, such as Figure 15A and 15B As shown in the diagram, the support portion 340 may include a second ball member 3430 and a support protrusion 3440. Alternatively, the support portion 340 may include only a plurality of support protrusions 3440.

[0153] The support protrusion 3440 may have a shape different from that of the spherical member. The support protrusion 3440 may protrude and have a curved shape, or it may have a hemispherical shape.

[0154] The reflective member 3100 may be disposed between the support portions 340. In this case, a plane extending from the reflective surface 3130 of the reflective member 3100 may pass through the second spherical member 3430. However, the arrangement of the reflective member 3100 is not limited to the above arrangement. For example, the reflective surface 3130 of the reflective member 3100 may be configured to face at least one of the support portions 340.

[0155] The rotating support portion 3300 or the reflector bracket 3200 may include a plurality of receiving recesses capable of accommodating the support portion 340. For example, the rotating support portion 3300 may include a second receiving recess 3310 disposed on the surface facing the reflector bracket 3200 to accommodate a portion of the support portion 340. Furthermore, the reflector bracket 3200 may include a third receiving recess 3220 disposed on the surface facing the rotating support portion 3300 to accommodate another portion of the support portion 340. The second receiving recess 3310 of the rotating support portion 3300 and the third receiving recess 3220 of the reflector bracket 3200 may be arranged to face each other in a second direction and configured to accommodate the support portion 340 in the second direction. Depending on the number of support portions 340, a plurality of second receiving recesses 3310 and third receiving recesses 3220 may be provided.

[0156] In an embodiment, to precisely align the relative positions of the reflector 3200 and the rotating support 3300, at least one of the plurality of second receiving recesses 3310 and the plurality of third receiving recesses 3220 can be configured to support the second ball member 3430 at at least three points. For example, at least one of the plurality of second receiving recesses 3310 can be a recess with at least three inclined surfaces, while the others can be recesses with at least two inclined surfaces. The second ball member 3430 can be supported in point contact on each inclined surface. Therefore, the second ball member 3430 can be supported at at least three points in the second receiving recess 3310 with three inclined surfaces, and can be supported at two points in the second receiving recess 3310 with two inclined surfaces. According to this support structure, the second ball member 3430 has a degree of freedom in one direction in one of the plurality of second receiving recesses 3310, thereby overcoming tolerance-related defects.

[0157] In another embodiment, when the support portion 340 includes a support protrusion 3440 and the support protrusion 3440 is disposed in the rotating support portion 3300, the rotating support portion 3300 may not have a receiving recess. Similarly, if the support protrusion 3440 is disposed on the reflector bracket 3200, the reflector bracket 3200 may not have a receiving recess.

[0158] The driving force for rotating the reflector bracket 3200 can be generated by the second driving unit 210. For example, the second driving unit 210 may include a second driving magnet 211 disposed on the reflector bracket 3200 and a second driving coil 212 disposed on the housing 1100. The driving force can be generated by the electromagnetic interaction between the second driving magnet 211 and the second driving coil 212.

[0159] The second driving magnet 211 and the second driving coil 212 can be configured to face each other in a third direction. The third direction can be perpendicular to both the first and second directions.

[0160] The second drive coil 212 can be disposed on the housing 1100. Multiple second drive coils 212 can be disposed to face multiple drive magnets.

[0161] The second driving magnet 211 can be magnetized in different polarity sequences in the rotation direction of the reflector bracket 3200. For example, the second driving magnet 211 can be magnetized to have an N pole, a neutral region, and an S pole in sequence in the rotation direction of the reflector bracket 3200.

[0162] The second sensing unit 220 may include a second position sensor 222 for detecting the position of the second sensing magnet 221. For example, the second position sensor 222 may include a Hall sensor as a magnetic sensor. The second position sensor 222 can detect the amount of movement of the second sensing magnet 221 by detecting changes in the magnetic flux passing through the second position sensor 222.

[0163] When one surface of the reflective module 3000 is parallel to one surface of the housing 1100 in a third direction, the second position sensor 222 can be configured to face the neutral region of the second sensing magnet 221. That is, the second position sensor 222 can be configured to face the boundary region between the N pole and the S pole of the second sensing magnet 221, thereby effectively detecting the displacement of the second sensing magnet 221.

[0164] Multiple second position sensors 222 can be arranged, and the signals detected by each second position sensor 222 can be compared with each other to more accurately detect position changes of the second sensing magnet 221.

[0165] The reflective support 3200 can be supported on the rotating bearing 3300 by a second magnetic force generated by a pair of magnetic members. The pair of magnetic members may include a first magnetic member 3240 and a second magnetic member 3340.

[0166] The first magnetic component 3240 may be disposed on one of the reflective bracket 3200 and the rotating bearing portion 3300, and the second magnetic component 3340 may be disposed on the other of the reflective bracket 3200 and the rotating bearing portion 3300.

[0167] At least one of the first magnetic component 3240 and the second magnetic component 3340 can be a traction magnet, and both the first magnetic component 3240 and the second magnetic component 3340 can be traction magnets.

[0168] Figure 12 This is a diagram illustrating the structure of a reflection module 3000 according to a second embodiment of the present disclosure. References to the above will be omitted below. Figures 3 to 11B The description given for the first embodiment is the same as that given.

[0169] The second drive unit 210 and the second sensing unit 220 can be disposed on top so that they are away from the lower surface of the housing 1100 in a first direction relative to the first drive unit 110 and the first sensing unit 120.

[0170] The second driving magnet 211 and the second sensing magnet 221 can be arranged parallel to each other in the second direction.

[0171] The second driving magnet 211 and the second sensing magnet 221 can be arranged adjacent to or spaced apart from each other in the reflective bracket 3200.

[0172] When the second driving magnet 211 and the second sensing magnet 221 are configured to be far from the lower surface of the housing 1100 in the first direction relative to the first driving magnet 111 and the first sensing magnet 121, the total length of the reflection module 3000 in the first direction can be increased.

[0173] Figure 13 , Figure 14A and Figure 14B This is a diagram illustrating the structure of a reflection module 3000 according to a third embodiment of the present disclosure. References to the above will be omitted below. Figures 3 to 11B The description given for the first embodiment is the same as that given.

[0174] In the second driving unit 210, only a single second driving magnet 211 can be arranged parallel to the only number of second sensing magnets 221. Similarly, only a single second driving coil 212 can be arranged facing the only number of second driving magnets 211. Furthermore, in the first driving unit 110, only a single first driving magnet 111 can be arranged parallel to the only number of first sensing magnets 121. Similarly, only a single first driving coil 112 can be arranged facing the only number of first driving magnets 111. Therefore, the overall size of the reflection module 3000 can be reduced.

[0175] The reflection module according to one or more embodiments of this disclosure can improve external magnetic field interference.
