Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2025-0052528, filed on April 22, 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 a reflection module and a camera module including a reflection module. Background Technology

[0004] Mobile devices may include a foldable camera module in which a reflective element is positioned in front of a lens to bend the path of light. Because such a foldable camera module can extend the path of light without increasing the thickness of the mobile device, it enables high-magnification zoom capabilities.

[0005] In this foldable camera module, optical image stabilization can be achieved through the dual-axis rotation of the reflector. For example, the reflector can rotate about any two of the roll, pitch, and yaw axes.

[0006] The camera module may be equipped with a spherical component for supporting the rotating reflector. The spherical component can move along the direction of rotation or act as a rotation axis while rotating in situ. However, since the spherical component is typically located between adjacent components, there is a possibility that it may detach due to various factors.

[0007] 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

[0008] 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.

[0009] In one general aspect, the reflective module includes: a reflective member including a reflective surface configured to change the propagation path of light from a first optical axis direction to a second optical axis direction; a reflective bracket on which the reflective member is mounted, the reflective bracket being rotatable together with the reflective member about a first rotation axis parallel to the second optical axis direction, wherein the reflective bracket rotates about the first rotation axis relative to a mating member; and a first hinge member disposed between the reflective bracket and the mating member, at least a portion of the first hinge member being resilient to support rotation of the reflective bracket about the first rotation axis.

[0050] 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.

[0051] 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.

[0052] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein are provided merely to illustrate some of the many possible ways in which the methods, apparatuses, and / or systems described herein will become apparent upon understanding this disclosure.

[0053] Throughout this specification, when an element such as a layer, region, or substrate is described as being "on," "connected to," or "attached to" another element, the element may be directly "on," directly "connected to," or directly "attached to" the other element, or there may be one or more other elements between the element and the other element. Conversely, when an element is described as being "directly on," "directly connected to," or "directly attached to" another element, there are no other elements between the element and the other element.

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

[0055] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited by these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, first part, first region, first layer, or first section mentioned in these examples may also be referred to as a second component, second part, second region, second layer, or second section.

[0056] Spatial relative terms such as “above,” “above,” “below,” and “under” may be used herein for descriptive convenience to describe the relationship of one element relative to another, as shown in the accompanying drawings. In addition to covering the orientation depicted in the drawings, these spatial relative terms are intended to also cover different orientations of the device in use or operation.

[0059] 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.

[0060] 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.

[0061] This disclosure relates to camera modules. The camera modules disclosed herein can be installed on portable electronic devices such as mobile communication terminals, smartphones, tablet PCs, etc.

[0062] Figure 1 This is a perspective view of a camera module according to an embodiment of the present disclosure. Figure 2A It is along Figure 1 The cross-sectional view taken from line I-I'. Figure 2B It is along Figure 1 The cross-sectional view taken from line II-II'. Figure 3 yes Figure 1 A schematic exploded stereoscopic view of the camera module.

[0063] Camera module 1 may include a housing 100 and optical elements disposed within the housing 100. The optical elements may include lenses for refracting light and reflective members for reflecting light. The reflective member may be a prism. The lens and reflective member may be arranged in combination with other components. For example, the lens may be configured as a first lens module 200 and a second lens module 400, and the reflective member may be configured as a reflective module 300.

[0064] The reflection module 300 can be located between the first lens module 200 and the second lens module 400 to bend the optical path. For example, light passing through the first lens module 200 can be reflected by the reflection module 300 and incident on the second lens module 400. For example, the optical axes of the first lens module 200 and the second lens module 400 can be different from each other and can be approximately perpendicular to each other.

[0065] Reference Figure 2A and Figure 2B The first lens module 200 and the reflection module 300 can be arranged along a first optical axis (Y-axis direction). The first optical axis (Y-axis direction) can correspond to the height direction of the camera module 1. The first lens module 200 can be connected to the upper side of the reflection module 300. Therefore, when performing optical image stabilization, the first lens module 200 can move together with the reflection module 300. The reflection module 300 and the second lens module 400 can be arranged along a second optical axis (Z-axis direction). The second optical axis (Z-axis direction) can correspond to the length direction of the camera module 1. The second lens module 400 can be spaced apart from the reflection module 300. The second lens module 400 can be configured to move when performing focus adjustment.

[0066] Although omitted in the accompanying drawings, camera module 1 may also include an image sensor disposed as an optical element within housing 100. Light incident on camera module 1 can ultimately reach the image sensor and can be converted into an electrical signal. The image sensor may be disposed within housing 100 such that its imaging surface faces the second lens module 400.

[0067] The camera module 1 may include a shield 500 attached to the housing 100. Since the housing 100 has a box shape that opens upwards, the shield 500 can be attached to the housing 100 to cover the open upper portion of the housing 100, thereby protecting the components. Furthermore, the shield 500 can shield electromagnetic waves.

[0068] The shield 500 may include an opening 510 for allowing light to enter the camera module 1. A first lens module 200 may be disposed in the opening 510, and light may enter the first lens module 200.

[0069] Figure 4A This is a top view of the housing according to an embodiment of the present disclosure. Figure 4B This is a side view of the housing according to an embodiment of the present disclosure. Figure 5 This is a perspective view of a housing (to which a substrate is attached) according to an embodiment of the present disclosure.

[0070] As described above, the optical element can be configured to be movable within the housing 100. For example, a hinge member can be disposed between the reflection module 300 and the housing 100, and a ball member can be disposed between the second lens module 400 and the housing 100. The hinge member and the ball member enable relative movement of the optical element relative to the housing 100.

[0071] Reference Figure 4A The housing 100 may include a receiving groove HG'2 for assembling a hinge member within the space where the reflection module 300 is housed. Furthermore, the housing 100 may include a ball guide groove BG' for inserting a ball member into the space where the second lens module 400 is housed. The number of ball guide grooves BG' may be set to correspond to the number of ball members disposed between the second lens module 400 and the housing 100.

[0072] Further reference Figure 4B The housing 100 may include through-holes TH in its side and bottom surfaces. A driving unit for driving the reflection module 300 and the second lens module 400 may be disposed in the through-hole TH. For example, the driving unit may include a driving magnet and a driving coil disposed facing each other, and the driving magnet and the driving coil may face each other through the through-hole TH.

[0073] Reference Figure 5 The substrate 600 can be attached to the outer surface of the housing 100. For example, at least a portion of the substrate 600 can be formed of a flexible material and can be disposed on multiple surfaces of the housing 100.

[0074] As described above, a portion of the drive unit can be mounted on the substrate 600. For example, a drive coil can be mounted on the substrate 600 and attached to the housing 100 via the substrate 600. Furthermore, position sensors and the like can also be mounted on the substrate 600.

[0075] Camera module 1 has focus adjustment and optical image stabilization functions. As described above, the focus adjustment function can be implemented through the second lens module 400, and the optical image stabilization function can be implemented through the reflection module 300. When optical image stabilization is performed, the first lens module 200 connected to the reflection module 300 can also move together.

[0076] First, the components related to the focus adjustment function of camera module 1 will be described.

[0077] Figure 6 Is with Figure 1 An exploded perspective view of the components related to the focus adjustment function of the camera module. Figure 7A and Figure 7B The position of the second lens barrel is shown during focus adjustment.

[0078] The second lens module 400 may include a second lens barrel 410 on which multiple lenses are mounted. The second lens barrel 410 may have multiple lenses mounted in the second optical axis direction (Z-axis direction).

[0079] The second lens barrel 410 can move relative to the housing 100 in the second optical axis direction (Z-axis direction).

[0080] The second lens module 400 may include a drive unit (hereinafter referred to as the AF drive unit) that generates a driving force to move the second lens barrel 410.

[0081] The AF drive unit may include an AF drive magnet 421 and an AF drive coil 423 arranged facing each other.

[0082] The AF drive unit may include at least one AF drive magnet 421 and at least one AF drive coil 423. The number of AF drive magnets 421 and AF drive coils 423 may be corresponding.

[0083] The AF driving magnet 421 can be disposed on the side surface of the second lens barrel 410, and the AF driving coil 423 can be disposed in the housing 100 facing the AF driving magnet 421. The AF driving coil 423 can be mounted on the substrate 600 and disposed in the through hole TH of the housing 100 facing the AF driving magnet 421.

[0084] The AF drive magnet 421 and AF drive coil 423 can generate a driving force in the second optical axis direction (Z-axis direction). The second lens barrel 410 can be moved along the second optical axis direction (Z-axis direction) by this driving force. When the second lens barrel 410 moves along the second optical axis direction (Z-axis direction), the distance between the multiple lenses and the image sensor mounted in the housing 100 can be changed, thereby performing focus adjustment of the camera module 1.

[0085] The AF drive unit may also include a position sensor 425 for sensing the position of the second lens barrel 410. The position sensor 425 may be disposed in the housing 100 together with the AF drive coil 423 in a state of being mounted on the substrate 600, and may face the AF drive magnet 421 through the through hole TH. For example, the position sensor 425 may be a Hall sensor.

[0086] The AF drive coil 423 and the position sensor 425 can be fixedly disposed in the housing 100, while the AF drive magnet 421 can be disposed in the second lens barrel 410 and thus can move together with the second lens barrel 410. The position sensor 425 can sense changes in the magnetic field formed by the AF drive magnet 421 to sense the position of the second lens barrel 410.

[0087] Multiple ball components 430 can be disposed between the second lens barrel 410 and the housing 100 to help the second lens barrel 410 move smoothly.

[0088] The multiple spherical components 430 can be configured in three or more. For example, the multiple spherical components 430 can consist of four spherical components (first spherical components to fourth spherical components). The four spherical components 430 can be divided into two groups to support one side and the other side of the second lens barrel 410, and the one side and the other side can be arranged relative to each other based on the second optical axis (Z axis).

[0089] Multiple ball components 430 can be inserted between ball guide grooves BG and BG' formed in the second lens barrel 410 and housing 100, respectively.

[0090] Multiple ball components 430 can be individually accommodated in ball guide grooves BG and BG' to roll along ball guide grooves BG and BG'. For example, ball guide grooves BG and BG' can have length in the second optical axis direction (Z-axis direction), and multiple ball components 430 can roll in ball guide grooves BG and BG' in the second optical axis direction (Z-axis direction).

[0091] The second lens barrel 410 can be in close contact with the housing 100, and has a plurality of ball members 430 therebetween. For example, a traction magnet 441 can be disposed in the second lens barrel 410, and a traction yoke 443 can be disposed in the housing 100 facing the traction magnet 441. The traction magnet 441 and the traction yoke 443 can generate an attractive force in a direction facing each other (e.g., in the first optical axis direction (Y-axis direction) of the figure). By means of this attractive force, the second lens barrel 410 can be supported on the housing 100 in the first optical axis direction (Y-axis direction).

[0092] The traction magnet 441 and the traction yoke 443 can be configured to be biased toward one side or the other relative to the second optical axis (Z axis).

[0093] For example, when the traction magnet 441 and the traction yoke 443 are configured to be biased to one side relative to the second optical axis (Z-axis), one side of the second lens barrel 410 can become the main guide. Conversely, when the traction magnet 441 and the traction yoke 443 are configured to be biased to the other side relative to the second optical axis (Z-axis), the other side of the second lens barrel 410 can become the main guide.

[0094] In this case, the cross-sectional shapes of the ball guide grooves BG and BG' located on one side of the second lens barrel 410 can be different from those of the ball guide grooves BG and BG' located on the other side of the second lens barrel 410. Some ball guide grooves BG and BG' may have different cross-sectional shapes than the rest.

[0095] Reference Figure 7A and Figure 7B The housing 100 may be provided with a stop 110 to restrict the movement of the second lens barrel 410.

[0096] The stop member 110 can be respectively disposed on the front side and the rear side of the second lens barrel 410. The second lens barrel 410 can move to a maximum position in the direction away from the image sensor (-Z direction) to collide with the stop member 110 disposed on the front side of the second lens barrel 410, and can move to a maximum position in the direction close to the image sensor (+Z direction) to collide with the stop member 110 disposed on the rear side of the second lens barrel 410.

[0097] The stop 110 may include a damper 111 for absorbing shock and noise. The damper 111 may be arranged to protrude toward the second lens barrel 410, and the second lens barrel 410 may collide with the damper 111.

[0098] Next, the configuration related to the optical image stabilization function of camera module 1 will be described.

[0099] Figure 8 It shows in Figure 1 The rotating axis in the optical imaging image stabilization process of the camera module.

[0100] The first lens module 200 and the reflection module 300 rotate about two rotation axes (hereinafter referred to as the first rotation axis A1 and the second rotation axis A2) to perform optical image stabilization of the camera module 1.

[0101] The first rotation axis A1 and the second rotation axis A2 can be perpendicular to each other. For example, the first rotation axis A1 can be formed parallel to the second optical axis (Z axis), and the second rotation axis A2 can be formed perpendicular to the first optical axis (Y axis) and the second optical axis (Z axis).

[0102] In this specification, rolling rotation or rolling means the rotational movement of the first lens module 200 and the reflection module 300 about the first rotation axis A1, and pitch rotation or pitch means the rotational movement of the first lens module 200 and the reflection module 300 about the second rotation axis A2.

[0103] Figure 9 This is an exploded perspective view of the reflector bracket and the rotating guide. Figure 10 This is a cross-sectional view of the first lens barrel and the reflecting member perpendicular to the first axis of rotation. Figure 11A and Figure 11B This illustrates the rotation of the first lens barrel and the reflecting component around the first rotation axis, and Figure 12 An embodiment in which the damper is disposed separately from the first hinge member is shown.

[0104] The first lens module 200 may include a first lens barrel 210 on which one or more lenses are mounted. The first lens barrel 210 may be equipped with one or more lenses in the first optical axis direction (Y-axis direction).

[0105] The first lens barrel 210 can be mounted in the reflection module 300. For example, the first lens barrel 210 can be mounted together with the reflection member 310 in the reflection bracket 320. Since the first lens barrel 210 and the reflection member 310 can be mounted together in the reflection bracket 320, the optical axis can be easily aligned. The first lens barrel 210 and the reflection member 310 can be arranged in the reflection bracket 320 in the direction of the first optical axis (Y-axis direction).

[0106] A spacer SP can be disposed between the first lens barrel 210 and the reflecting member 310. The spacer SP can also be mounted in the reflecting bracket 320. The spacer SP can have an entrance aperture through which light passes. Therefore, light can pass through the first lens module 200 and be incident on the reflecting member 310.

[0107] The reflection module 300 may include a reflection member 310, a reflection bracket 320, and a rotation guide 330.

[0108] The reflecting member 310 can be disposed on the reflecting bracket 320. The reflecting member 310 can be a light reflecting member and can be configured as a prism having an incident surface, a reflecting surface and an exit surface.

[0109] The reflective member 310 can change the optical axis of the incident light from the first optical axis (Y-axis) to the second optical axis (Z-axis). To this end, the incident surface of the reflective member 310 can be perpendicular to the first optical axis (Y-axis), the exit surface can be perpendicular to the second optical axis (Z-axis), and the reflective surface can be tilted at approximately 45 degrees relative to both the first optical axis (Y-axis) and the second optical axis (Z-axis).

[0110] The reflector bracket 320 and the rotation guide 330 are movable (rotatable) relative to the housing 100. Specifically, the reflector bracket 320 can rotate relative to the rotation guide 330 and the housing 100 based on a first rotation axis A1, and the reflector bracket 320 and the rotation guide 330 can rotate relative to the housing 100 based on a second rotation axis A2.

[0111] The reflection module 300 may include a drive unit (hereinafter referred to as the OIS drive unit) that generates a driving force for rotating the reflection bracket 320 and the rotation guide 330.

[0112] The OIS drive unit may include an OIS drive magnet 341 and an OIS drive coil 343 arranged facing each other. The OIS drive magnet 341 and the OIS drive coil 343 can provide a driving force for rotating the reflection module 300 about a first rotation axis A1 and a second rotation axis A2.

[0113] The OIS driving magnet 341 can be disposed on the reflector bracket 320. For example, the OIS driving magnet 341 can be disposed on the side surface of the reflector bracket 320.

[0114] Furthermore, the OIS driving magnet 341 may include multiple magnets. For example, the OIS driving magnet 341 may include four magnets.

[0115] In an embodiment, based on the accompanying drawings, the four magnets can be configured with two magnets on each of the two sides of the reflective bracket 320 spaced apart along the X-axis, and the reflective member 310 is located between the two sides of the reflective bracket 320.

[0116] Based on the accompanying drawings (e.g., Figure 9 The protrusions 321 protruding in the X-axis direction can be spaced apart from each other on both sides of the reflective support 320. For example, the protrusions 321 can be spaced apart in the second optical axis direction (Z-axis direction). Four magnets can be disposed on the protrusions 321.

[0117] The OIS driving magnet 341 can be magnetized so that the surface facing the OIS driving coil 343 has both N and S poles. For example, the surface of the OIS driving magnet 341 facing the OIS driving coil 343 can be provided with N pole, neutral region and S pole in sequence in the first optical axis direction (Y axis direction).

[0118] The number of OIS drive coils 343 can be set to correspond to the number of OIS drive magnets 341. For example, the OIS drive coils 343 can include four coils, and the four coils can be arranged in a one-to-one manner facing the four magnets.

[0119] The OIS drive coil 343 can be mounted on the substrate 600 and can be disposed in the housing 100. The OIS drive coil 343 can be disposed in the through hole TH of the housing 100 and can directly face the OIS drive magnet 341.

[0120] When power is supplied to the OIS drive coil 343, the OIS drive magnet 341 and the OIS drive coil 343 can generate the driving force required to rotate around the first rotation axis A1, and also generate the driving force required to rotate around the second rotation axis A2.

[0121] For example, the OIS drive unit can rotate the reflector bracket 320 and the rotation guide 330 by adjusting the driving force formed by the four magnets constituting the OIS drive magnet 341 and the four coils constituting the OIS drive coil 343. For example, the directions of the driving force formed by the diagonally spaced pairs of magnets and coils can be opposite to each other.

[0122] The reflection module 300 may also include a position sensor 345 for sensing the position of the reflection bracket 320.

[0123] The position sensor 345 can be mounted on the substrate 600 together with the OIS drive coil 343, and can be disposed in the housing 100. The position sensor 345 and the OIS drive coil 343 can be mounted on the same surface of the substrate 600, and the position sensor 345 can also directly face the OIS drive magnet 341 through the through hole TH.

[0124] Position sensor 345 can sense changes in the magnetic field generated by OIS-driven magnet 341 to sense the position of reflective bracket 320. For example, position sensor 345 can be a Hall sensor.

[0125] The OIS drive coil 343 and position sensor 345 can be fixedly mounted on the housing 100, while the OIS drive magnet 341 can be mounted on the reflector bracket 320 and thus can rotate together with the reflector bracket 320. Therefore, the position sensor 345 can sense changes in the magnetic field formed by the OIS drive magnet 341 to sense the position of the reflector bracket 320.

[0126] In another embodiment, the position sensor 345 and the OIS drive coil 343 can be mounted on different surfaces of the substrate 600. In this case, the sensing magnet 346 can be disposed on the reflective support 320 to face the position sensor 345.

[0127] Reference Figure 9 The sensing magnet 346 can be disposed on the rear surface of the reflector bracket 320 (the surface connecting the two side surfaces of the reflector bracket 320). One or more sensing magnets 346 can be disposed. Based on the accompanying drawings, when two sensing magnets 346 are disposed, the two sensing magnets 346 can be spaced apart in the X-axis direction, with the first rotation axis A1 located between them. Two position sensors 345 can also be disposed, each facing one of the two sensing magnets 346.

[0128] The position sensor 345 can be fixedly mounted in the housing 100, while the sensing magnet 346 can rotate together with the reflective bracket 320, so that the position sensor 345 can sense the change in the magnetic field formed by the sensing magnet 346 to sense the position of the reflective bracket 320.

[0129] A hinge member (hereinafter referred to as the first hinge member) 350 supporting the rotation of the reflector bracket 320 may be disposed between the reflector bracket 320 and the rotation guide 330.

[0130] The first hinge member 350 may be made of a rigid and elastic material to support the rotation of the reflector bracket 320. Therefore, at least a portion of the first hinge member 350 may deform or bend.

[0131] The reflector bracket 320 and the rotation guide 330 can be spaced apart by the first hinge member 350. Therefore, the reflector bracket 320 can rotate relative to the rotation guide 330.

[0132] In an embodiment, based on the accompanying drawings, the first hinge member 350 may include two hinge members spaced apart in the X-axis direction, and the reflective member 310 is located between the two hinge members.

[0133] In this embodiment, the first hinge member 350 may be disposed between the OIS driving magnets 341. On both sides of the reflective bracket 320, the OIS driving magnets 341 may be spaced apart in the second optical axis direction (Z-axis direction), and the first hinge member 350 may be disposed between the OIS driving magnets 341.

[0134] The first hinge component 350 may include a first base 351 disposed on the reflector bracket 320, a second base 352 disposed on the rotation guide 330, and a hinge portion (or hinge shaft) 353 connecting the first base 351 and the second base 352.

[0135] The first base 351 and the second base 352 can be fixed to the reflector bracket 320 and the rotating guide 330 respectively by adhesives or the like.

[0136] The reflector bracket 320 and the rotating guide 330 may be respectively provided with receiving grooves HG1 and HG'1, and the first base 351 and the second base 352 are respectively assembled into receiving grooves HG1 and HG'1. The receiving groove HG1 of the reflector bracket 320 and the receiving groove HG'1 of the rotating guide 330 may be arranged to face each other.

[0137] The receiving groove HG1 of the reflector bracket 320 and the receiving groove HG'1 of the rotary guide 330 can be arranged to face each other between the protrusions 321. Therefore, a portion of the rotary guide 330 can be located between the protrusions 321.

[0138] Adhesive can be applied to receiving grooves HG1 and HG'1, and the first base 351 and the second base 352 can be fixed to receiving grooves HG1 and HG'1 respectively by adhesive.

[0139] Based on the accompanying drawings, the first base 351 and the second base 352 can be configured to face each other in the X-axis direction, with a hinge portion 353 therebetween.

[0140] The hinge portion 353 may have an elongated profile that extends between the first base 351 and the second base 352 in a direction parallel to the first rotation axis A1, and may be one or more, wherein the first rotation axis A1 may be the rotation axis of the reflector bracket 320.

[0141] The hinge portion 353 can be formed to have a thickness that is relatively thinner than the thickness of each of the first base 351 and the second base 352, thereby possessing elasticity.

[0142] By bending the hinge portion 353, the reflector bracket 320 can rotate about the first rotation axis A1 at a predetermined angle. In this case, the first base 351 can rotate together with the reflector bracket 320. For example, the first base 351 can rotate relative to the second base 352 via the hinge portion 353.

[0143] When the reflector bracket 320 rotates around the first rotation axis A1, the gap between the first base 351 and the second base 352 can change.

[0144] For example, when the reflector bracket 320 rotates clockwise relative to the drawing (hereinafter referred to as the first direction), the first base 351 can move closer to the second base 352 at the lower end of the left hinge member and the upper end of the right hinge member, while moving further away from the second base 352 at the upper end of the left hinge member and the lower end of the right hinge member (see Figure 1). Figure 11B Conversely, when the reflector bracket 320 rotates counterclockwise relative to the drawing (hereinafter referred to as the second direction), the first base 351 can move closer to the second base 352 at the upper end of the left hinge member and the lower end of the right hinge member, while moving further away from the second base 352 at the lower end of the left hinge member and the upper end of the right hinge member (see Figure 1). Figure 11A ).

[0145] When the reflector bracket 320 rotates to its maximum angle around the first rotation axis A1 in either the first or second direction, the first base 351 and the second base 352 can contact each other, thereby limiting the rotation range of the reflector bracket 320. In this case, the first hinge member 350 can be used as a stop. Furthermore, the first hinge member 350 can be formed of an elastic material and therefore can be used as a damper to absorb shocks and noise.

[0146] The above description of the first hinge member 350 can also be applied to other hinge members described below, and can be directly applied or appropriately modified according to each embodiment.

[0147] Reference Figure 12 Damper members DP1 and DP2 can be separately provided from the first hinge member 350. Damper members DP1 and DP2 can be formed of elastic material and can serve as stops to limit the rotation range of the reflector bracket 320 while also mitigating impacts.

[0148] Damper components DP1 and DP2 can be respectively disposed on the bottom surface of the reflector bracket 320 and on a surface of the rotation guide 330 facing the bottom surface of the reflector bracket 320 in the first optical axis direction (Y-axis direction). Figure 11A and Figure 11B As shown, when the reflector bracket 320 rotates about the first rotation axis A1, the damper member DP1 and the damper member DP2 can come into contact with each other. For example, when the reflector bracket 320 rotates, the damper member DP1 and the damper member DP2 can come into contact first, and then the first base 351 and the second base 352 of the first hinge member 350 can come into contact.

[0149] Figure 13 This is an exploded perspective view of the rotating guide and the housing. Figure 14This is a cross-sectional view of the first lens barrel and the reflecting member perpendicular to the second axis of rotation, and Figure 15A and Figure 15B The diagram shows the first lens barrel and the reflecting component rotating about the second rotation axis.

[0150] As described above, the rotation guide 330 can rotate relative to the housing 100 based on the second rotation axis A2.

[0151] Between the rotary guide 330 and the housing 100, a hinge member (hereinafter referred to as the second hinge member) 370 that supports the rotation of the rotary guide 330 may be provided.

[0152] The second hinge member 370 may be made of a rigid and elastic material to support the rotation of the rotary guide 330. Therefore, at least a portion of the second hinge member 370 may deform or bend.

[0153] The rotation guide 330 is spaced apart from the housing 100 by the second hinge member 370. Therefore, the rotation guide 330 can rotate relative to the housing 100.

[0154] In an embodiment, the second hinge member 370 may be provided as one, and the center of the second hinge member 370 may be located approximately on the second optical axis (Z-axis).

[0155] In this embodiment, the center of the second hinge member 370 may be approximately located on the second optical axis (Z-axis), and a pair of magnetic members 361 and 363 may be provided on each side of the second hinge member 370. For example, the pair of magnetic members 361 and 363 may be a traction magnet 361 provided on the rotation guide 330 and a traction yoke 363 provided on the housing 100. The traction yoke 363 can be provided by being inserted into the housing 100.

[0156] The pair of magnetic components 361 and 363 can be configured to generate a magnetic attraction in a direction facing each other. For example, magnetic components 361 and 363 can face each other in a first optical axis direction (Y-axis direction) and generate an attraction in the first optical axis direction (Y-axis direction).

[0157] The rotating guide 330 can be supported on the housing 100 by the magnetic attraction generated by the magnetic components 361 and 363.

[0158] The second hinge component 370 may include a first base 371 disposed on the rotation guide 330, a second base 372 disposed on the housing 100, and a hinge portion (or hinge shaft) 373 connecting the first base 371 and the second base 372.

[0159] The first base 371 and the second base 372 can be fixed to the rotating guide 330 and the housing 100 respectively by adhesives or the like.

[0160] The rotating guide 330 and the housing 100 may be respectively provided with receiving grooves HG2 and HG2', and the first base 371 and the second base 372 are respectively inserted into receiving grooves HG2 and HG2'. The receiving groove HG2 of the rotating guide 330 and the receiving groove HG'2 of the housing 100 may be arranged to face each other.

[0161] Adhesive can be applied to receiving grooves HG2 and HG'2, and the first base 371 and the second base 372 can be fixed to receiving grooves HG2 and HG'2 respectively by adhesive.

[0162] Based on the accompanying drawings, the first base 371 and the second base 372 can be configured to face each other in the Y-axis direction, with a hinge portion 373 therebetween.

[0163] The hinge portion 373 may have an elongated profile that extends between the first base 371 and the second base 372 in a direction parallel to the second rotation axis A2, and may be one or more, wherein the second rotation axis A2 may be the rotation axis of the rotation guide 330.

[0164] The hinge portion 373 can be formed to have a thickness that is relatively thinner than the thickness of each of the first base 371 and the second base 372 in order to be flexible.

[0165] The rotation guide 330 can rotate by a predetermined angle about the second rotation axis A2 relative to the hinge portion 373, which is the center. In this case, the first base 371 can rotate together with the rotation guide 330. For example, the first base 371 can rotate relative to the second base 372 via the hinge portion 373.

[0166] When the rotating guide 330 rotates relative to the second rotating axis A2, the gap between the first base 371 and the second base 372 can be changed.

[0167] For example, when the rotation guide 330 rotates in the first direction, the first base 371 can be close to the second base 372 on the front side of the hinge member (right side in the figure) based on the hinge portion 373, and the first base 371 can be away from the second base 372 on the rear side of the hinge member (left side in the figure) (see...). Figure 15AConversely, when the rotation guide 330 rotates in the second direction, the first base 371 can be close to the second base 372 on the rear side of the hinge member (left side in the figure) based on the hinge portion 373, and the first base 371 can be away from the second base 372 on the front side of the hinge member (right side in the figure) (see...). Figure 15B ).

[0168] When the rotation guide 330 is rotated to its maximum extent about the second rotation axis A2 in either the first or second direction, the first base 371 and the second base 372 may collide with each other. The second hinge member 370 may be formed of an elastic material, and may also function as a damper to absorb shock and noise even when they collide with each other.

[0169] Reference Figure 13 Damper members DP3 and DP4 can be disposed separately from the second hinge member 370 within the housing 100. Damper members DP3 and DP4 can be disposed in the form of a frame attached to and inserted into the housing 100. Damper members DP3 and DP4 can be made of an elastic material to mitigate impacts while serving as stops to limit the rotational range of the rotational guide 330.

[0170] Damper members DP3 and DP4 can be configured to protrude from the bottom surface of housing 100 toward reflector bracket 320 or rotary guide 330, and include a third damper member DP3 disposed on the front side (right side in the figure) of the second hinge member 370 and a fourth damper member DP4 disposed on the rear side (left side in the figure) of the second hinge member 370. (Refer to...) Figure 14 The third damper component DP3 may protrude toward the bottom surface of the reflector bracket 320, and the fourth damper component DP4 may protrude toward the bottom surface of the rotation guide 330.

[0171] like Figure 15A As shown, when the rotation guide 330 rotates in the first direction, the reflector bracket 320 can contact the third damper member DP3, and as... Figure 15B As shown, when the rotation guide 330 rotates in the second direction, the rotation guide 330 can contact the fourth damper member DP4. The bottom surface of the rotation guide 330 may be provided with a protrusion 331 protruding toward the fourth damper member DP4, and the protrusion 331 of the rotation guide 330 can contact the fourth damper member DP4.

[0172] Figure 16 This is an exploded perspective view of a reflection module according to another embodiment. Figure 17 This is a cross-sectional view of the first lens barrel and the reflecting member perpendicular to the first axis of rotation. Figure 18A and Figure 18B The diagram illustrates the rotation of the first lens barrel and the reflecting component around the first rotation axis, and... Figure 19 A modified example of the first hinge component is shown.

[0173] According to another embodiment of this disclosure, the position of the first hinge member 350 disposed between the reflector bracket 320 and the rotation guide 330 can be changed.

[0174] In one embodiment, the first hinge member 350 may be disposed on the bottom surface side of the reflector bracket 320.

[0175] The first hinge member 350 can be configured as one, and the center of the first hinge member 350 can be approximately located on the first rotation axis A1.

[0176] The first base 351 of the first hinge member 350 can be assembled into a receiving groove HG1 disposed on the bottom surface of the reflector bracket 320, and the second base 352 can be assembled into a receiving groove HG'1 disposed on a surface of the rotation guide 330 facing the bottom surface of the reflector bracket 320. The hinge portion 353 can connect the first base 351 and the second base 352, and can have an elongated profile extending in the direction of the first rotation axis A1.

[0177] For example, when the reflector bracket 320 rotates in the first direction, the first base 351 can be positioned on the right side of the second base 352 relative to the hinge portion 353, and the first base 351 can be positioned on the left side of the second base 352 (see...). Figure 18B Conversely, when the reflector bracket 320 rotates in the second direction, the first base 351 can be positioned on the left side closer to the second base 352 relative to the hinge portion 353, and the first base 351 can be positioned on the right side further away from the second base 352 (see [link]). Figure 18A ).

[0178] As described above, the first hinge member 350 can itself have a damper function.

[0179] Reference Figure 19 The first hinge member 350 may include protrusions 351a and 352a, which are formed to protrude from the first base 351 and the second base 352 toward each other, respectively.

[0180] The protrusions 351a and 352a may include a first protrusion 351a disposed on a first base 351, and a second protrusion 352a disposed on a second base 352 to face the first protrusion 351a.

[0181] Protrusions 351a and 352a may be provided on both sides based on the hinge portion 353. Preferably, protrusions 351a and 352a may be provided in the corners of the first base 351 and the second base 352, respectively.

[0182] Protrusions 351a and 352a may extend in the direction of the first rotation axis A1, similar to hinge portion 353. Protrusions 351a and 352a may extend from the first base 351 and the second base 352 respectively in a direction facing each other, but may be configured to be unconnected, spaced apart, and to contact or move away from each other depending on the rotation direction of the reflector bracket 320. When the reflector bracket 320 rotates to its maximum extent, protrusions 351a and 352a may perform the functions of a stop and a damper by first contacting each other.

[0183] As described above, damper components DP1 and DP2 can be disposed separately from the first hinge component 350 between the reflector bracket 320 and the rotation guide 330.

[0184] Damper members DP1 and DP2 can be provided on both sides of the first hinge member 350 (or relative to the first rotation axis A1). The damper members DP1 and DP2 on one side and the damper members DP1 and DP2 on the other side can be spaced apart in the X-axis direction relative to the first hinge member 350 (or relative to the first rotation axis A1).

[0185] The damper components DP1 and DP2 include a first damper component DP1 disposed on the reflector bracket 320 and a second damper component DP2 disposed on the rotation guide 330. The first damper component DP1 may be disposed at a corner adjacent to the bottom surface of the reflector bracket 320, and the second damper component DP2 may be disposed in the rotation guide 330 so as to face the first damper component DP1 in the first optical axis direction (Y-axis direction).

[0186] The gap formed between the first damper member DP1 and the second damper member DP2 in the first optical axis direction (Y-axis direction) can be equal to or narrower than the gap formed between the first base 351 and the second base 352 in the first optical axis direction (Y-axis direction). Therefore, when the reflector bracket 320 rotates, the first damper member DP1 and the second damper member DP2 can contact first, and then the first base 351 and the second base 352 of the first hinge member 350 can contact.

[0187] Figure 20 This is a cross-sectional view of the first lens barrel and the reflecting member perpendicular to the second axis of rotation, and Figure 21A and Figure 21BThe diagram shows the first lens barrel and the reflecting component rotating about the second rotation axis.

[0188] According to another embodiment of this disclosure, the ball component 380 may be disposed between the rotation guide 330 and the housing 100.

[0189] The ball member 380 may include a plurality of ball members, such as two ball members, which are spaced apart from each other in the direction of the second rotation axis A2 and may form the second rotation axis A2. For example, the second rotation axis A2 may pass through the ball member 380. The rotation guide 330 may be supported by the ball member 380 and may rotate about the second rotation axis A2 relative to the housing 100.

[0190] The rotary guide 330 and the housing 100 may each be provided with a receiving groove BG3 and a receiving groove BG'3 for accommodating the ball member 380. The receiving groove BG3 of the rotary guide 330 and the receiving groove BG'3 of the housing 100 may be arranged to face each other, and the ball member 380 may be assembled between the receiving groove BG3 and the receiving groove BG'3.

[0191] In an embodiment, the rotation guide 330 may include an extension 333 extending along the X-axis in its main body portion, such as the mounting reflector bracket 320, and a receiving groove BG3 of the rotation guide 330 may be disposed in the extension 333. The housing 100 may include a protruding wall 130 at a position corresponding to the extension 333 of the rotation guide 330, and a receiving groove BG'3 of the housing 100 may be disposed in the protruding wall 130. The extension 333 of the rotation guide 330 may be supported by the protruding wall 130 of the housing 100, and a ball member 380 is therein.

[0192] In some receiving grooves BG3 and BG'3, the ball member 380 may be supported at three points, and the ball member 380 may rotate in situ while being fixed in position within the receiving grooves BG3 and BG'3. In the remaining receiving grooves BG3 and BG'3, the ball member 380 may be supported at two points.

[0193] According to another embodiment of this disclosure, the rotation guide 330 can be in close contact with the housing 100, with a ball member 380 therebetween. A pair of magnetic members 361 and 363 can be arranged to face each other on the rotation guide 330 and the housing 100. The pair of magnetic members 361 and 363 can generate an attractive force in a first optical axis direction (Y-axis direction) facing each other, and the rotation guide 330 can be supported on the housing 100 by the attractive force. For example, the pair of magnetic members 361 and 363 can be a traction magnet 361 disposed on the rotation guide 330 and a traction yoke 363 disposed on the housing 100. The traction yoke 363 can be disposed and inserted into the housing 100.

[0194] According to another embodiment, the first rotation axis A1 corresponding to the rolling axis may be supported by the first hinge member 350, and the second rotation axis A2 corresponding to the pitch axis may be supported by the ball member 380.

[0195] When rotating about the rolling axis, the reflective support 320 can move relative to the rotation guide 330 along the first optical axis direction (Y-axis direction). Therefore, when the rolling rotation is supported by a ball member, there is a risk of the ball member detaching because the gap between the receiving grooves in which the ball member is received widens. According to an embodiment of this disclosure, since the rolling rotation is supported by the first hinge member 350, the detachment of the ball member can be prevented.

[0196] On the other hand, when rotating about the pitch axis, the rotation guide 330 can move relative to the housing 100 along the second optical axis direction (Z-axis direction). Therefore, when the ball member 380 is supported by rotation, the possibility of the ball member 380 disengaging is low because the gap between the receiving grooves in which the ball member 380 is housed does not widen significantly.

[0197] This disclosure provides a camera module with improved drive stability during optical imaging image stabilization.

[0198] According to one or more embodiments of this disclosure, drive stability during optical imaging stabilization can be improved because there is no need to worry about the separation of the ball component.
