[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2024-0073891, filed on June 5, 2024, with the Korean Intellectual Property Office, and Korean Patent Application No. 10-2024-0138443, filed on October 11, 2024, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

[0003] The following disclosure relates to a reflection module and a camera module including the reflection module. Background Technology

[0004] Camera modules used in mobile devices have been manufactured to offer performance comparable to that of a typical camera.

[0005] For example, camera modules used in mobile devices may include reflective elements. Because reflective elements bend the path of light, the light path can be sufficiently extended without increasing the thickness of the mobile device, thereby improving the performance of the camera module.

[0006] When optical image stabilization (OIS) is performed on a camera module, the reflector can be configured to rotate while mounted on another component. In the example, the camera module may include a ball bearing that supports the rotation of the reflector. The ball bearing acts similarly to a wheel and can assist the movement of the reflector with relatively small force. However, depending on the mounting position of the ball bearing, it may be significantly affected by forces that impede the drive, which could in turn hinder smooth operation. Utility Model Content

[0060] The features described herein may be embodied in various forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein are provided merely to illustrate some of the many possible ways in which the methods, apparatus, and / or systems described herein will be apparent upon understanding the disclosure of this application. In this document, the use of the term “may” (e.g., regarding what an example or implementation may include or implement) with respect to an example or implementation means that there exists at least one example or implementation that includes or implements such a feature, and that all examples or implementations are not limited thereto.

Figure 3 This is a schematic exploded perspective view of an exemplary camera module according to one or more embodiments. Figure 4A It is along Figure 1 A cross-sectional view taken from line I-I'.

[0065] A camera module 100 according to one or more embodiments may include a reflection module 2000, a lens module 3000, an image sensor module 4000, and a housing 1100 and an outer casing 1300 that house the aforementioned components.

[0066] The reflection module 2000 can be configured to change the direction of travel of incident light incident on the camera module 100. Therefore, the reflection module 2000 may include a reflective member 2100 for reflecting incident light.

[0067] Reference Figure 2 and Figure 4A The reflective member 2100 of the reflective module 2000 can reflect incident light incident in the thickness direction (Y-axis direction) of the camera module 100 to the length direction (Z-axis direction) of the camera module 100.

[0068] The lens module 3000 may include multiple lenses that refract incident light passing through the reflection module 2000. The multiple lenses may be arranged in the longitudinal direction (hereinafter referred to as the optical axis direction) (Z-axis direction) of the camera module 100.

[0069] Reference Figure 3 The image sensor module 4000 may include an image sensor 4100 and a printed circuit board (hereinafter referred to as a sensor substrate) 4200 on which the image sensor 4100 is mounted.

[0070] Incident light passing through lens module 3000 can be incident on image sensor 4100, and image sensor 4100 can convert incident light into electrical signals.

[0071] One or more baffles (not shown) can be placed between the lens module 3000 and the image sensor 4100 to reduce flare. The baffles can be arranged within the interior space of the housing 1100 described below.

[0072] In addition, the image sensor module 4000 may also include an optical filter 4300, which filters light that passes through the lens module 3000 and is incident on the image sensor 4100. In this example, the optical filter 4300 may be an infrared cutoff filter.

[0073] Figure 6 It is a perspective view of a housing according to one or more embodiments.

[0074] Reference Figure 6 The housing 1100 may have an internal space. Within the internal space of the housing 1100, the reflection module 2000 and the lens module 3000 may be arranged sequentially in the direction of the incident light's travel.

[0075] The image sensor module 4000 can be disposed behind the lens module 3000. The image sensor module 4000 can be connected to the outer surface of the housing 1100, so that the imaging surface of the image sensor 4100 is exposed to the internal space of the housing 1100.

[0076] In this way, when the reflection module 2000 and the lens module 3000 are arranged in a single housing 1100, the number of parts can be reduced, thus facilitating assembly and eliminating the need for separate alignment of the optical axes of the reflection module 2000 and the lens module 3000.

[0077] However, this is merely an example, and unlike those shown in the accompanying drawings, the reflection module 2000 and the lens module 3000 can be housed in separate housings. The housings containing the reflection module 2000 and the lens module 3000 can be connected to each other.

[0078] According to one embodiment, a printed circuit board (hereinafter referred to as a main substrate) 5000 on which drive coils and the like are mounted can be arranged on the outer surface of the housing 1100.

[0079] Figure 7 It is a perspective view of the main substrate according to one or more embodiments, and Figure 8 This is a perspective view showing a main substrate connected to a housing according to one or more embodiments.

[0080] According to an embodiment, the main substrate 5000 may be bent in some portions to be arranged on multiple surfaces of the housing 1100. For example, the main substrate 5000 may be configured to cover the side surfaces of the housing 1100.

[0081] In the example, refer to Figure 6 The housing 1100 may include through holes 1101, 1103, 1105 and 1107, and the drive coils mounted on the main substrate 5000 and the image sensor 4100 may be exposed to the internal space of the housing 1100 through the through holes 1101, 1103, 1105 and 1107.

[0082] The outer casing 1300 can be attached to the housing 1100 to cover the open upper portion of the housing 1100. In an embodiment, the outer casing 1300 may include a metallic material to serve as a shield.

[0083] Reference Figure 2 The housing 1300 may include an opening 1310 through which light passes. Light can be incident on the reflective module 2000 through the opening 1310.

[0084] According to one or more embodiments, the camera module 100 may substantially have optical image stabilization (OIS) and autofocus (AF) functions.

[0085] In one implementation, to compensate for jitter (e.g., hand tremors), the reflection module 2000 can be configured to rotate about two axes (X-axis and Y-axis). Additionally, to adjust the focus, the lens module 3000 can be configured to be movable in the optical axis direction (Z-axis direction).

[0086] Therefore, the reflection module 2000 and the lens module 3000 can be arranged in the housing 1100 via a spherical component. The movement of the reflection module 2000 and the lens module 3000 can be a relative movement with respect to the housing 1100.

[0087] In the example, the camera module 100 according to one or more embodiments may also have a zoom function. The zoom function can be achieved by moving the lens module 3000 in the optical axis direction (Z-axis direction), and for this purpose, the lens module 3000 may include a plurality of independently drivable lens barrels.

[0088] Figure 9 This is a perspective view of a reflection module 2000 according to one or more embodiments. Figure 10A This is an exploded perspective view of a reflection module 2000 according to one or more embodiments. Figure 10B From and Figure 10A Exploded stereoscopic views of the 2000 reflection module observed from different angles. Figure 11 It is along Figure 9The cross-sectional view taken from line III-III'. Figure 12 This is a bottom-view perspective view of a reflection module 2000 according to one or more embodiments, and Figure 13 This is a bottom view of a reflection module 2000 (supporting part 2300) according to one or more embodiments.

[0089] According to an embodiment, the reflection module 2000 may include a reflection bracket 2200 and a support portion 2300. A reflection member 2100 is disposed on the reflection bracket 2200, and the reflection bracket 2200 is supported on the support portion 2300. The support portion 2300 may be rotatably supported by the housing 1100, which also rotatably supports the reflection bracket 2200.

[0090] According to an embodiment, the reflecting member 2100 may be configured as a prism including an incident surface 2110, a reflecting surface 2120, and an exiting surface 2130. However, this is only an example, and in this example, the reflecting member 2100 may be configured as a mirror.

[0091] When the direction of incident light is defined as the first optical axis OA1, which is parallel to the thickness direction (Y-axis direction) of camera module 100, the first optical axis OA1 can pass through the center of incident surface 2110. Furthermore, when the optical axis direction (Z-axis direction) of camera module 100 is defined as the second optical axis OA2, the second optical axis OA2 can pass through the center of exit surface 2130.

[0092] The reflecting surface 2120 may be disposed at an angle relative to the incident surface 2110 and the exit surface 2130. In the example, the first optical axis OA1 and the second optical axis OA2 may intersect approximately at the center of the reflecting surface 2120. The reflecting surface 2120 may change the direction of travel of incident light incident in the direction of the first optical axis OA1 to the direction of the second optical axis OA2.

[0093] In a non-limiting example, the incident surface 2110 and the exit surface 2130 of the reflecting member 2100 may have curvature. (See reference...) Figure 11 The incident surface 2110 may have a convex shape, and the exit surface 2130 may have a concave shape. However, the shapes of the incident surface 2110 and the exit surface 2130 are not limited to the shapes described above.

[0094] Since the incident surface 2110 and the exit surface 2130 can have curvature, the reflecting member 2100 can be used as a lens. Therefore, when the incident surface 2110 and the exit surface 2130 of the reflecting member 2100 have curvature, some lenses can be omitted from the lens module 3000, thereby reducing the size of the camera module 100.

[0095] Reference Figure 10ASpacers SP1 and SP2 can be provided on the object side of the incident surface 2110 and the image side of the exit surface 2130, respectively. For example, spacer SP1 can be provided between the reflector 2100 and the housing 1300, and spacer SP2 can be provided between the reflector 2100 and the housing 1100.

[0096] Spacers SP1 and SP2 may include openings through which incident light passes and light-blocking portions disposed along the periphery of the openings. The light-blocking portions may be black-coated portions and may cover the periphery of the effective areas of the incident surface 2110 and the exit surface 2130 to block light from passing through the corresponding areas.

[0097] According to the implementation, the reflection module 2000 can be configured to rotate about two axes (X-axis and Y-axis) perpendicular to the optical axis (Z-axis).

[0098] In one embodiment, the reflector bracket 2200 can rotate about a first axis (X-axis) while being supported by the support portion 2300, and the support portion 2300 can rotate together with the reflector bracket 2200 about a second axis (Y-axis) while being supported by the housing 1100. The first axis (X-axis) and the second axis (Y-axis) can be perpendicular to each other.

[0099] The reflective member 2100 disposed in the reflective bracket 2200 can rotate together with the reflective bracket 2200. Therefore, the reflective member 2100 can rotate about the first axis (X-axis) and the second axis (Y-axis).

[0100] The first ball component 2410 can be disposed between the reflector bracket 2200 and the support portion 2300 to support the rotation of the reflector bracket 2200 relative to the support portion 2300.

[0101] In one embodiment, the first ball member 2410 may include a plurality of ball members spaced apart from each other in the first axis (X-axis) direction and with the reflective member 2100 inserted therebetween.

[0102] The first ball component 2410 can rotate in situ while being fixed in place relative to the reflector bracket 2200 and the support portion 2300, forming a first axis (X-axis). The first axis (X-axis) can pass through the first ball component 2410.

[0103] The reflector bracket 2200 and the support portion 2300 may include receiving recesses 2221 and 2321 for receiving the first ball member 2410. Each of the receiving recesses 2221 and 2321 may be arranged to be spaced apart from each other in a first axial direction (X-axis direction) and may be provided in a number corresponding to the number of the first ball members 2410.

[0104] In one embodiment, the reflector 2200 may include a first receiving recess 2221 to receive a portion of the first spherical member 2410, and the support portion 2300 may include a second receiving recess 2321 disposed facing the first receiving recess 2221 and receiving another portion of the first spherical member 2410. In an example, the first receiving recess 2221 and the second receiving recess 2321 may face each other in the optical axis direction (Z-axis direction).

[0105] The first spherical member 2410 may be supported at three points or two points by the first receiving recess 2221 and the second receiving recess 2321. That is, the first receiving recess 2221 and the second receiving recess 2321 may each include three or two inclined surfaces.

[0106] In one embodiment, the first receiving recess 2221 and the second receiving recess 2321 may each include three inclined surfaces, allowing the first ball member 2410 to rotate in situ. Furthermore, the first receiving recess 2221 or the second receiving recess 2321 may include two inclined surfaces to overcome defects caused by tolerances.

[0107] The reflector bracket 2200 can be supported on the support portion 2300 by magnetic force (magnetic attraction). Therefore, a pair of magnetic components that generate magnetic attraction can be provided on the reflector bracket 2200 and the support portion 2300.

[0108] Reference Figure 11 A pair of magnetic components may include a traction magnet 2340 disposed in the support portion 2300 and a traction yoke 2240 inserted in the reflective bracket 2200.

[0109] A pair of magnetic components can generate a magnetic attraction in the direction in which they face each other. For example, a pair of magnetic components can face each other in the optical axis direction (Z-axis direction), and a magnetic attraction can be generated between them in the optical axis direction (Z-axis direction). Therefore, the reflective support 2200 can be supported on the bearing portion 2300 in the optical axis direction (Z-axis direction).

[0110] In the example, the direction in which the reflector 2200 is supported by the support portion 2300 can match the direction in which the reflector 2200 and the support portion 2300 face each other, and the first ball member 2410 is inserted between the reflector 2200 and the support portion 2300. Therefore, the first ball member 2410 can support the rotation of the reflector 2200 without disengaging from between the reflector 2200 and the support portion 2300.

[0111] The reflection module 2000 may include a first drive unit that provides driving force to rotate the reflection bracket 2200.

[0112] The first drive unit may include a first drive magnet 2231 and a first drive coil 2232 arranged facing each other. The reflector 2200 may rotate about a first axis (X-axis) by the electromagnetic interaction between the first drive magnet 2231 and the first drive coil 2232.

[0113] In one embodiment, the first driving magnet 2231 can be disposed in the reflective bracket 2200, and the first driving coil 2232 can be disposed in the housing 1100. However, in another embodiment, the positions of the first driving magnet 2231 and the first driving coil 2232 can be interchanged.

[0114] The reflector bracket 2200 may include an extension 2210 extending from the reflector bracket 2200 and located between the support portion 2300 and the housing 1100, and the first drive magnet 2231 may be disposed on the extension 2210.

[0115] The first drive coil 2232 can be mounted on the main substrate 5000 and can be disposed on one surface of the housing 1100. The first drive coil 2232 can be exposed to the interior space of the housing 1100 through a through hole 1101 formed in the housing 1100, and can therefore directly face the first drive magnet 2231.

[0116] In this embodiment, the first driving magnet 2231 and the first driving coil 2232 can face each other in the optical axis direction (Z-axis direction).

[0117] The first driving magnet 2231 can be magnetized in a second axial direction (Y-axis direction), which is approximately the rotation direction of the reflector 2200. For example, a surface of the first driving magnet 2231 facing the first driving coil 2232 may include an N-pole (S-pole) region, a neutral region, and an S-pole (N-pole) region in the second axial direction (Y-axis direction).

[0118] The first driving unit may further include a first yoke (not shown) facing the first driving magnet 2231, and a first driving coil 2232 inserted between the first driving magnet 2231 and the first yoke.

[0119] The first yoke can be disposed on the other side of the housing 1100, which is the surface of the housing 1100 opposite to the surface on which the first drive coil 2232 is disposed. In the example, the first yoke can be configured as a magnetic component and can concentrate the magnetic flux of the first drive magnet 2231.

[0120] Additionally, the first drive unit may include a first position sensing unit (or sensor) for detecting the position of the reflector bracket 2200. The first position sensing unit may include a first sensing magnet 2235 and a first position sensor 2233 arranged facing each other. In this example, the first position sensor 2233 may be configured as a Hall sensor and may detect changes in magnetic flux to detect the amount of movement of the reflector bracket 2200.

[0121] The first sensing magnet 2235 can be disposed together with the first driving magnet 2231 on the extension 2210 of the reflector bracket 2200. The first sensing magnet 2235 can be disposed in the second axial direction (Y-axis direction) and spaced apart from the first driving magnet 2231.

[0122] Additionally, one surface of the first sensing magnet 2235 facing the first position sensor 2233 may include an N-pole (S-pole) region, a neutral region, and an S-pole (N-pole) region in the second axial direction (Y-axis direction).

[0123] In an embodiment, the first driving magnet 2231 and the first sensing magnet 2235 may be configured such that the same polarity regions (N pole and N pole or S pole and S pole) are adjacent to each other.

[0124] The first position sensor 2233 can be disposed on the main substrate 5000. The first position sensor 2233 can be configured to face the neutral region of the first sensing magnet 2235 when the reflective bracket 2200 is in the middle position.

[0125] According to the implementation method, since the first position sensor 2233 is spaced apart from the first drive coil 2232, the first position sensor 2233 can be less affected by the magnetic field of the first drive coil 2232, thereby improving the sensing accuracy.

[0126] The second ball component 2420 can be disposed between the support portion 2300 and the housing 1100 to support the rotation of the support portion 2300 relative to the housing 1100.

[0127] In one embodiment, the second ball component 2420 may include a single pivot ball 2421 and a guide ball 2422 spaced apart from the pivot ball 2421.

[0128] The pivot ball 2421 can rotate in situ while remaining in a fixed position relative to the support portion 2300 and the housing 1100, forming a second axis (Y-axis). The second axis (Y-axis) can pass through the pivot ball 2421.

[0129] The support portion 2300 and the housing 1100 may include receiving recesses 2322 and 1122 for receiving the pivot ball 2421.

[0130] In one embodiment, the support portion 2300 may include a third receiving recess 2322 that receives a portion of the pivot ball 2421, and the housing 1100 may include a fourth receiving recess 1122 that is disposed facing the third receiving recess 2322 and receives another portion of the pivot ball 2421. For example, the third receiving recess 2322 and the fourth receiving recess 1122 may face each other in the second axial direction (Y-axis direction).

[0131] The pivot ball 2421 can be supported at three points by the third receiving recess 2322 and the fourth receiving recess 1122. The third receiving recess 2322 and the fourth receiving recess 1122 can each include three inclined surfaces, so that the pivot ball 2421 can rotate in place.

[0132] The guide ball 2422 can be spaced apart from the second axis (Y-axis) which is the rotation axis of the support part 2300, and can support the rotation of the support part 2300 relative to the second axis (Y-axis).

[0133] The guide ball 2422 may include two ball components spaced apart from each other in a generally first axial direction (X-axis direction).

[0134] The support portion 2300 and the housing 1100 may include guide recesses 2323 and 1123 for accommodating guide balls 2422. The guide recesses 2323 and 1123 may be spaced apart in a first axial direction (X-axis direction) and may be provided in a number corresponding to the number of guide balls 2422.

[0135] In one embodiment, the support portion 2300 may include a first guide recess 2323 that accommodates a portion of the guide ball 2422, and the housing 1100 may include a second guide recess 1123 that is configured to face the first guide recess 2323 and accommodate another portion of the guide ball 2422. For example, the first guide recess 2323 and the second guide recess 1123 may face each other in a second axial direction (Y-axis direction).

[0136] The first guide recess 2323 and the second guide recess 1123 can extend generally in the rotational direction of the support portion 2300. For example, the first guide recess 2323 and the second guide recess 1123 can extend along an arc of a circle based on the second axis (Y-axis) (curved shape), or they can extend in the normal direction of the circle (straight shape). Therefore, the guide ball 2422 can guide the rotation of the support portion 2300 while being accommodated in the first guide recess 2323 and the second guide recess 1123.

[0137] In an embodiment, the first guide recess 2323 and the second guide recess 1123 may each have a flat bottom surface, and the guide ball 2422 may contact the flat bottom surfaces of the first guide recess 2323 and the second guide recess 1123.

[0138] In other words, the guide ball 2422 can roll on the bottom surfaces of the guide recesses 2323 and 1123, while being supported by a point on each of the first guide recess 2323 and the second guide recess 1123. In this example, since the guide recesses 2323 and 1123 do not restrict the side surfaces of the guide ball 2422, the rolling of the guide ball 2422 can be smooth.

[0139] According to the embodiment, the angle θ between the guide balls 2422 centered on the pivot ball 2421 can be 90° or less, preferably an acute angle. Angle θ can be defined as the angle formed by two lines connecting the center of each of the guide balls 2422 and the center of the pivot ball 2421. The angle θ between the guide balls 2422 can be set within a rotation range (degrees) according to the rotation range of the support portion 2300. When the support portion 2300 rotates, the guide balls 2422 can change position within the space defined by the guide recesses 2323 and 1123, but regardless of the position of the guide balls 2422, the angle θ between the guide balls 2422 centered on the pivot ball 2421 can remain a constant acute angle.

[0140] The support portion 2300 can be supported by the housing 1100 by magnetic force (magnetic attraction). Therefore, a pair of magnetic members that generate magnetic attraction can be provided in the support portion 2300 and the housing 1100. The pair of magnetic members can be arranged to face each other in the direction between the housing 1100 and the reflecting member 2100.

[0141] A pair of magnetic components may include a traction magnet 2350 disposed in the support portion 2300 and a traction yoke 1160 inserted into the housing 1100.

[0142] A pair of magnetic components can generate a magnetic attraction in the direction in which they face each other. For example, a pair of magnetic components can face each other in the second axial direction (Y-axis direction) and can generate a magnetic attraction between them in the second axial direction (Y-axis direction). Therefore, the support portion 2300 can be supported in the housing 1100 in the second axial direction (Y-axis direction).

[0143] In the example, the orientation of the support portion 2300 supported in the housing 1100 can match the orientation of the support portion 2300 and the housing 1100 facing each other and the orientation of the second ball member 2420 inserted between the support portion 2300 and the housing 1100. Therefore, the second ball member 2420 will not detach from the support portion 2300 and the housing 1100, and can support the rotation of the support portion 2300.

[0144] According to the embodiment, the traction magnet 2350 disposed on the support portion 2300 can be positioned within a support region T having a generally triangular shape defined by the second ball member 2420. Similarly, the traction yoke 1160 disposed on the housing 1100 facing the traction magnet 2350 can also be positioned within the support region T defined by the second ball member 2420.

[0145] Preferably, when the support portion 2300 rotates about the second axis (Y-axis), both the traction magnet 2350 and the traction yoke 1160 can be continuously positioned within the support region T defined by the second ball member 2420. However, this does not necessarily mean that the traction magnet 2350 and the traction yoke 1160 are completely located within the support region T, and may include examples where a portion of them is located within the support region T.

[0146] Reference Figure 13 In this embodiment, when the support portion 2300 rotates about the second axis (Y-axis), the center of the magnetic attraction formed by the traction magnet 2350 and the traction yoke 1160 can be located within the support region T. The center of the magnetic attraction formed by the traction magnet 2350 and the traction yoke 1160 can be approximately aligned with the geometric center CP of the traction magnet 2350. Therefore, when the support portion 2300 rotates about the second axis (Y-axis), the center of the magnetic attraction can be consistently located within the support region T.

[0147] When the center of the magnetic attraction formed by the traction magnet 2350 and the traction yoke 1160 is constantly located within the support region T defined by the second ball member 2420 during the rotation of the support portion 2300, the support portion 2300 can rotate stably.

[0148] In one embodiment, the traction magnet 2350 can be configured such that its geometric center CP is spaced approximately from the pivot ball 2421 along the optical axis (Z-axis direction). Therefore, the rotation center of the support portion 2300 and the center of magnetic attraction that presses the support portion 2300 against the housing 1100 can be approximately located along the optical axis (Z-axis).

[0149] Additionally, refer to again Figure 13The traction magnet 2350 can be configured to be closer to the pivot ball 2421 in the second ball member 2420 than the guide ball 2422 in the second ball member 2420 defining the support region T. For example, the distance between the geometric center CP of the traction magnet 2350 and the pivot ball 2421 can be shorter than the distance between the geometric center CP of the traction magnet 2350 and the guide ball 2422.

[0150] When the support portion 2300 rotates, the shape of the support region T defined by the second ball member 2420 can change. For example, since the guide ball 2422 supports the rotation of the support portion 2300 while rolling within the guide recesses 2323 and 1123, the position of the guide ball 2422 can be changed within the guide recesses 2323 and 1123. In the example, the pivot ball 2421 can form the rotation axis of the support portion 2300 while rotating in situ while being accommodated in the receiving recesses 2322 and 1122.

[0151] Therefore, when the traction magnet 2350 is positioned close to the pivot ball 2421, although the shape of the support region T changes continuously according to the rotation of the support portion 2300, the possibility that the traction magnet 2350 is located within the support region T defined by the second ball member 2420 can be increased. Thus, the rotation of the support portion 2300 can be supported more stably.

[0152] The reflection module 2000 may include a second drive unit that provides driving force to rotate the support portion 2300.

[0153] The second drive unit may include a second drive magnet 2331 and a second drive coil 2332 arranged facing each other. The support portion 2300 may rotate about a second axis (Y-axis) based on the electromagnetic interaction between the second drive magnet 2331 and the second drive coil 2332.

[0154] In one embodiment, the second driving magnet 2331 may be disposed in the support portion 2300, and the second driving coil 2332 may be disposed in the housing 1100. However, this is only an example, and in another embodiment, the positions of the second driving magnet 2331 and the second driving coil 2332 may be interchanged.

[0155] The second driving magnet 2331 may be disposed on the side surface of the support portion 2300. For example, the second driving magnet 2331 may include two magnets, which may be respectively arranged on opposite sides of the support portion 2300.

[0156] According to the embodiment, the second driving magnet 2331 can be disposed on different sides of the second ball member 2420 and the support portion 2300. Therefore, the dimensions of the second driving magnet 2331 and the second driving coil 2332 can be increased, and since the distance from the rotation center to the driving center can be increased, the driving force and driving efficiency can be improved.

[0157] In this example, the second drive coil 2332 can be mounted on the main substrate 5000 and disposed within the housing 1100. In this example, the second drive coil 2332 may include two coils corresponding one-to-one with the second drive magnet 2331, and the two coils may be arranged on opposite sides of the housing 1100, respectively, opposite to the opposite sides of the support portion 2300. The second drive coil 2332 can be exposed to the internal space of the housing 1100 through a through-hole 1103 formed in the housing 1100, thereby directly facing the second drive magnet 2331.

[0158] In this embodiment, the second driving magnet 2331 and the second driving coil 2332 may face each other in the first axial direction (X-axis direction).

[0159] The second driving magnet 2331 can be magnetized in the optical axis direction (Z-axis direction), which is approximately the rotation direction of the support portion 2300. In the example, a surface of the second driving magnet 2331 facing the second driving coil 2332 may include an N-pole (S-pole) region, a neutral region, and an S-pole (N-pole) region in the optical axis direction (Z-axis direction).

[0160] The second drive unit may include a second position sensing unit (or sensor) for detecting the position of the carrier 2300. The second position sensing unit may include a second sensing magnet 2335 and a second position sensor 2333 arranged facing each other. In a non-limiting example, the second position sensor 2333 may be configured as a Hall sensor and may detect changes in magnetic flux to detect the amount of movement of the carrier 2300.

[0161] The second sensing magnet 2335 can be disposed together with the second driving magnet 2331 on one side or the opposite side of the support portion 2300. The second sensing magnet 2335 can be spaced apart from the second driving magnet 2331 in the optical axis direction (Z-axis direction).

[0162] Additionally, one surface of the second sensing magnet 2335 facing the second position sensor 2333 may include an N-pole (S-pole) region, a neutral region, and an S-pole (N-pole) region in the optical axis direction (Z-axis direction).

[0163] In an embodiment, the second driving magnet 2331 and the second sensing magnet 2335 can be arranged such that the same polarity regions (N pole and N pole or S pole and S pole) are adjacent to each other.

[0164] The second position sensor 2333 can be disposed on the main substrate 5000. When the support portion 2300 is in the middle position, the second position sensor 2333 can be disposed facing the neutral region of the second sensing magnet 2335.

[0165] According to the embodiment, the second position sensor 2333 can be positioned separately from the second drive coil 2332, and therefore, the second position sensor 2333 can be less affected by the magnetic field of the second drive coil 2332, thereby improving the sensing accuracy.

[0166] The reflection module 2000 may include auxiliary components 2500 to prevent collisions between the reflection module 2000 and adjacent structures.

[0167] The auxiliary member 2500 can be attached to the opposite side of the support portion 2300 to surround a portion of the reflector bracket 2200. Therefore, even in the event of an impact, separation of the reflector bracket 2200 and the support portion 2300 can be prevented.

[0168] The auxiliary component 2500 may include a damper. The damper can collide with the opposite portion before colliding with the injection-molded product, thereby absorbing the impact and noise caused by the collision.

[0169] In addition, according to one or more embodiments, the buffer member 1500 may be disposed between the housing 1100 and the support portion 2300.

[0170] Figure 14 This is an exploded perspective view of the housing and the support portion according to one or more embodiments, and Figure 15 It is along Figure 9 A cross-sectional view taken from line IV-IV'.

[0171] The buffer member 1500 can protrude from the bottom surface of the housing 1100 toward the bottom surface of the support portion 2300 that faces the bottom surface of the housing 1100. That is, the buffer member 1500 can protrude in a second axial direction (Y-axis direction), which is the thickness direction of the camera module 100.

[0172] In some embodiments, the cushioning member 1500 may be part of the housing 1100. In one example, the cushioning member 1500 may be integrally formed with the housing 1100 by insert injection molding. (See also...) Figure 15The rigid support frame 1150 can be inserted into the bottom surface of the housing 1100, and the buffer member 1500 can be attached to the rigid support frame 1150 and disposed in the housing 1100.

[0173] The buffer member 1500 can be used to absorb vibrations and noise caused by driving or impact. The buffer member 1500 can be formed of a flexible material that can be elastically deformed, and by way of example only, it can include materials such as urethane, rubber, silicone and sponge.

[0174] Refer again Figure 14 The buffer member 1500 may be disposed in the receiving portion 2360, which is disposed on the bottom surface of the supporting portion 2300. The buffer member 1500 may be disposed in the receiving portion 2360 with a small gap between it and the inner surface defining the receiving portion 2360.

[0175] The buffer member 1500 may be spaced apart from the rotation axis (or pivot ball 2421) of the support portion 2300 inserted therebetween in the first axial direction (X-axis direction).

[0176] The buffer member 1500 may function as a stop that limits the maximum amount of rotation of the load-bearing part 2300 relative to the housing 1100.

[0177] The buffer member 1500 can be spaced apart from the inner surface of the defining receiving portion 2360 in the optical axis direction (Z-axis direction). When the bearing portion 2300 rotates about the second axis (Y-axis), the buffer member 1500 can deform while making contact with some of the inner surface facing the optical axis direction (Z-axis direction). Therefore, the rotation range of the bearing portion 2300 can be limited, and the impact and noise caused by the rotation of the bearing portion 2300 can be reduced.

[0178] Additionally, the buffer member 1500 may have a gap between itself and the bottom surface of the receiving portion 2360 in the second axial direction (Y-axis direction). In this example, the gap between the buffer member 1500 and the receiving portion 2360 in the second axial direction (Y-axis direction) may be narrower than the gap between the support portion 2300 and the housing 1100 in the second axial direction (Y-axis direction). Therefore, when an impact is applied to the camera module 100 in the second axial direction (Y-axis direction), the support portion 2300 may first collide with the buffer member 1500, and direct collision with the housing 1100 may be prevented.

[0179] Figure 16 It is an exploded perspective view of a lens module according to one or more embodiments, and Figure 17 It is a bottom-view exploded perspective view of a lens module according to one or more embodiments.

[0180] Reference Figure 16 and Figure 17 The lens module 3000 may include a plurality of lens barrels 3110 and 3120 and a lens holder 3200 disposed therein, one of the plurality of lens barrels 3110 and 3120. The lens holder 3200 may be movably disposed within the internal space of the housing 1100.

[0181] Multiple lens barrels 3110 and 3120 may each include one or more lenses arranged or disposed in the optical axis direction (Z-axis direction).

[0182] In an embodiment, the plurality of lens barrels 3110 and 3120 may include a first lens barrel 3110 fixedly disposed in the internal space of the housing 1100 and a second lens barrel 3120 disposed to be movable relative to the housing 1100.

[0183] The second lens barrel 3120 can be connected to the lens holder 3200, and can move together with the lens holder 3200 relative to the housing 1100 and the first lens barrel 3110 in the optical axis direction (Z-axis direction) along the optical axis.

[0184] The lens holder 3200 may include two side surfaces arranged parallel to each other. The two side surfaces of the lens holder 3200 may extend from opposite sides of the second lens barrel 3120 in the optical axis direction (Z-axis direction). In the example, the two side surfaces of the lens holder 3200 may extend between the first lens barrel 3110 and the housing 1100, and a portion of the first lens barrel 3110 may be located between the two side surfaces of the lens holder 3200.

[0185] The third ball member 3430 may be located between the lens support 3200 and the housing 1100 to support the movement of the lens support 3200 relative to the housing 1100. In the example, the third ball member 3430 may be located between the two sides of the lens support 3200 and the housing 1100.

[0186] In one embodiment, the third spherical member 3430 may include a plurality of spherical members supporting a first and second side of the lens holder 3200, the plurality of spherical members being arranged on opposite sides of the second lens barrel 3120 based on an optical axis (Z-axis). In one example, the first and second sides of the lens holder 3200 may be supported by a plurality of spherical members spaced apart from each other in the optical axis direction (Z-axis direction). As another example, the first side of the lens holder 3200 may be supported by a plurality of spherical members, and the second side of the lens holder 3200 may be supported by a single spherical member.

[0187] Reference Figure 17 The lens holder 3200 and the housing 1100 may include guide recesses 3221 and 1124 for receiving the third ball member 3430.

[0188] A third guide recess 3221 having a length in the optical axis direction (Z-axis direction) can be disposed on the first and second sides of the lens holder 3200. In the example, the third guide recess 3221 can be disposed on the bottom surface of both side surfaces of the lens holder 3200. A fourth guide recess 1124 having a length in the optical axis direction (Z-axis direction) can be disposed in the housing 1100. The fourth guide recess 1124 can face the third guide recess 3221, and the third ball member 3430 is located between the fourth guide recess 1124 and the third guide recess 3221.

[0189] The third ball component 3430 can support the movement of the lens holder 3200 while being inserted between the third guide recess 3221 and the fourth guide recess 1124, and rolls in the optical axis direction (Z-axis direction).

[0190] The lens holder 3200 can be supported by the housing 1100 by magnetic force (magnetic attraction). Therefore, a pair of magnetic components that generate magnetic attraction can be provided in the lens holder 3200 and the housing 1100.

[0191] A pair of magnetic components may include a traction magnet 3240 disposed in the lens holder 3200 and a traction yoke (not shown) disposed in the housing 1100.

[0192] A pair of magnetic components can generate a magnetic attraction in a direction facing each other. In this example, the pair of magnetic components can face each other in the second axial direction (Y-axis direction), and a magnetic attraction can be generated between them in the second axial direction (Y-axis direction). Therefore, the lens holder 3200 can be supported in the housing 1100 in the second axial direction (Y-axis direction).

[0193] In the example, the direction in which the lens support 3200 is supported on the housing 1100 can be consistent with the direction in which the lens support 3200 and the housing 1100 face each other and the third ball member 3430 is located between them. Therefore, the third ball member 3430 will not detach from the lens support 3200 and the housing 1100, and can support the movement of the lens support 3200.

[0194] The lens module 3000 may include a third drive unit that provides driving force to move the lens holder 3200.

[0195] The third drive unit may include a third drive magnet 3231 and a third drive coil 3232 arranged facing each other. The lens holder 3200 may move in the optical axis direction (Z-axis direction) based on the electromagnetic interaction between the third drive magnet 3231 and the third drive coil 3232.

[0196] In one embodiment, the third driving magnet 3231 can be disposed in the lens holder 3200, and the third driving coil 3232 can be disposed in the housing 1100. However, in another embodiment, the positions of the third driving magnet 3231 and the third driving coil 3232 can be interchanged.

[0197] The third driving magnet 3231 can be disposed on the side surface of the lens holder 3200. In the example, the third driving magnet 3231 may include two magnets, which can be disposed on both sides of the lens holder 3200 respectively.

[0198] The third drive coil 3232 can be mounted on the main substrate 5000 and disposed within the housing 1100. In this example, the third drive coil 3232 may include two coils corresponding one-to-one with the third drive magnet 3231, and the two coils may be disposed on opposite sides of the housing 1100 opposite to the opposite sides of the lens support 3200. The third drive coil 3232 can be exposed to the internal space of the housing 1100 through a through-hole 1105 formed in the housing 1100, thereby directly facing the third drive magnet 3231.

[0199] In this embodiment, the third driving magnet 3231 and the third driving coil 3232 may face each other in the first axial direction (X-axis direction).

[0200] The third driving magnet 3231 can be magnetized in the optical axis direction (Z-axis direction), which is the direction of movement of the lens support 3200. In the example, a surface of the third driving magnet 3231 facing the third driving coil 3232 can be provided with an N-pole (S-pole) region, a neutral region, and an S-pole (N-pole) region in the optical axis direction (Z-axis direction).

[0201] The third drive unit may include a third position sensor 3233 for detecting the position of the lens holder 3200. In this example, the third position sensor 3233 may be configured as a Hall sensor and may detect changes in magnetic flux to detect the amount of movement of the lens holder 3200.

[0202] The third position sensor 3233 can be disposed on the main substrate 5000, and can be disposed on the inner or outer side of the third drive coil 3232. The third position sensor 3233 can be configured to face the neutral region of the third drive magnet 3231 when the lens holder 3200 is in the middle position.

[0203] The housing 1100 may include at least a pair of stops 1400 that face each other in the optical axis direction (Z-axis direction) and between which the lens module 3000 is located. For example, the stops 1400 may be configured to be fitted into the wall of the housing 1100.

[0204] The stop 1400 may include a damper projecting toward the lens module 3000. The damper may be configured to face the lens holder 3200 in the optical axis direction (Z-axis direction) to prevent direct collision between the lens holder 3200 and the housing 1100. In the example, when the lens holder 3200 has moved to its maximum value, the damper in the stop 1400 may collide with the lens holder 3200 before colliding with the injection-molded product, thereby absorbing vibrations and noise caused by the collision.

[0205] According to one or more embodiments, the driving stability of the reflection module and the optical image stabilization performance of the camera module can be improved.
