[0036] Throughout the accompanying drawings and detailed embodiments, the same reference numerals refer to the same elements. For purposes of clarity, illustration, and convenience, the drawings may not be drawn to scale, and the relative dimensions, scale, and depiction of elements in the drawings may be exaggerated. Detailed Implementation

[0037] The following detailed embodiments are provided to help the reader gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein, except for operations that must occur in a specific order, as will become apparent upon understanding the disclosure of this application. Furthermore, for clarity and conciseness, descriptions of features well-known in the art may be omitted.

[0038] The features described herein may be implemented in various forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein are provided merely to illustrate some of the many possible ways in which the methods, apparatuses, and / or systems described herein will become apparent upon understanding the disclosure of this application.

[0039] 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.

[0040] As used herein, the term “and / or” includes any one of the associated listed items and any combination of any two or more items.

[0041] 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.

[0042] Spatial relative terms such as “above,” “above,” “below,” and “under” may be used herein for descriptive convenience to describe the relationship of one element relative to another, as shown in the accompanying drawings. In addition to covering the orientation depicted in the drawings, these spatial relative terms are intended to also cover different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “above” another element would be located “below” or “under” that other element. Thus, depending on the spatial orientation of the device, the term “above” covers both orientations of “above” and “below”. The device may also be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0043] The terminology used herein is for the purpose of describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the terms “a,” “an,” and “the” are intended to include the plural form as well. The terms “comprising,” “including,” and “having” indicate the presence of the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not preclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0044] This disclosure relates to camera modules, which can be installed in portable electronic devices such as mobile communication terminals, smartphones, and tablet PCs.

[0045] Figure 1 This is a perspective view of a camera module according to an embodiment of the present disclosure. Figure 2 yes Figure 1 An exploded stereoscopic view of the camera module. Figure 3 yes Figure 1 The camera module has had its stereoscopic image removed from the casing, and Figure 4 It is shown Figure 3 A 3D view of the first lens module in a decomposed state.

[0046] Reference Figures 1 to 4 The camera module may include a first lens module 2100, a reflection module 3000, a second lens module 2200, and a housing 1000.

[0047] The first lens module 2100 may include at least one lens and a first lens barrel 2110. The at least one lens may have a first optical axis (X-axis) and be mounted in the first lens barrel 2110. The first optical axis (X-axis) may be relative to... Figure 4 It extends in the vertical direction.

[0048] The first lens module 2100 can be disposed in front of the reflection module 3000. Here, "in front of the reflection module 3000" can refer to the direction relative to the reflection module 3000 in the positive first optical axis (X-axis) direction (+X-axis direction). For example, the first lens module 2100 can be disposed higher than the reflection module 3000 in the direction of the first optical axis (X-axis).

[0049] The first lens module 2100 can be connected to the reflection module 3000. For example, the first lens module 2100 can be connected to the bracket 3200 of the reflection module 3000 (see...). Figure 5 ) connection.

[0050] The reflection module 3000 may include a reflection member 3100 (see...) Figure 5 The reflecting member 3100 may include a reflective surface that reflects light passing through the first lens module 2100. For example, the reflecting member 3100 may be a prism or a mirror. The reflecting member 3100 may be coupled to the bracket 3200.

[0051] The first lens module 2100 and the reflection module 3000 can be housed in the housing 1000.

[0052] In one embodiment, the camera module may further include a second lens module 2200. The reflection module 3000 may be disposed between the first lens module 2100 and the second lens module 2200. The second lens module 2200 may include multiple lenses and a second lens barrel 2210 (see...). Figure 12 Multiple lenses may have a second optical axis (Z-axis) and be mounted in the second lens barrel 2210.

[0053] The first optical axis (X-axis) of the first lens module 2100 and the second optical axis (Z-axis) of the second lens module 2200 can be perpendicular to each other.

[0054] The first lens module 2100 may include one or more lenses, and the second lens module 2200 may include multiple lenses.

[0055] When viewed along the first optical axis (X-axis), one or more lenses of the first lens module 2100 may be circular. When viewed along the second optical axis (Z-axis), at least one lens of the plurality of lenses of the second lens module 2200 may be non-circular (this feature is not shown in the figures). For example, a non-circular lens may have different lengths in two directions perpendicular to the second optical axis (Z-axis) and perpendicular to each other. In an embodiment, the length of the non-circular lens in the third axis (Y-axis) direction, which is perpendicular to both the first optical axis (X-axis) and the second optical axis (Z-axis), may be longer than the length of the non-circular lens in the first optical axis (X-axis) direction.

[0056] Although the camera module is described in the specification as including a first lens module 2100 and a second lens module 2200, the camera module is not limited thereto, and the camera module may also be configured to include only one of the first lens module 2100 and the second lens module 2200.

[0057] In one embodiment, the first lens module 2100 and the reflective member 3100 can be configured to rotate together for jitter correction. That is, the first lens module 2100 and the reflective member 3100 can rotate together about two axes perpendicular to each other.

[0058] For example, the first lens module 2100 and the reflective member 3100 can rotate together about the first optical axis (X-axis) as the rotation axis, and can also rotate together about the third axis (Y-axis) which is perpendicular to both the first optical axis (X-axis) and the second optical axis (Z-axis) as the rotation axis.

[0059] In one embodiment, the second lens module 2200 can be moved in the direction of the second optical axis (Z-axis) to adjust the focus.

[0060] The camera module may also include an image sensor module 8000.

[0061] The image sensor module 8000 may include a sensor housing 8300, an image sensor 8100, and a printed circuit board 8200, and may also include an infrared blocking filter (not shown in the figures).

[0062] An infrared blocking filter can be mounted on the sensor housing 8300. The infrared blocking filter can be used to block light in the infrared region from reaching the image sensor 8100.

[0063] The printed circuit board 8200 can be connected to the sensor housing 8300, and the image sensor 8100 can be mounted on the printed circuit board 8200.

[0064] Light passing through the second lens module 2200 can be received by the image sensor module 8000 (e.g., image sensor 8100).

[0065] The camera module may also include a housing 1100. The housing 1100 may be attached to the housing 1000 to cover the upper part of the housing 1000. The housing 1100 may have an opening, and the first lens module 2100 may be disposed in the opening.

[0066] At least a portion of the first lens module 2100 may be configured to protrude outside the housing 1000.

[0067] Figure 5 This is a perspective view of a reflection module according to an embodiment of the present disclosure. Figure 6 yes Figure 5 An exploded stereoscopic view of the reflection module, and Figure 7 yes Figure 6 A bottom-view stereoscopic view of the reflective module.

[0068] Reference Figures 5 to 7 The reflection module 3000 may include a reflection component 3100, a bracket 3200, and a guide component 3300.

[0069] The reflecting member 3100 may have a reflective surface that reflects light that has passed through the first lens module 2100. For example, the reflecting member 3100 may be a prism or a mirror.

[0070] When the reflecting member 3100 is a prism, the reflecting member 3100 can be a rectangular solid or a cube that is divided into two halves in the diagonal direction. The prism can include an incident surface into which light enters, a reflecting surface that reflects light that has passed through the incident surface, and an exiting surface into which light reflected from the reflecting surface exits.

[0071] The reflective member 3100 can be mounted on the bracket 3200. The first lens module 2100 can be disposed in front of the reflective member 3100. In this embodiment, the first lens module 2100 can be mounted on the bracket 3200.

[0072] The bracket 3200 is disposed on the guide member 3300 and configured to rotate relative to the guide member 3300. The guide member 3300 is disposed in the housing 1000 and configured to rotate relative to the housing 1000.

[0073] The guide member 3300 can rotate about a first optical axis (X-axis) as a rotation axis. For example, the guide member 3300 can rotate relative to the housing 1000 about the first optical axis (X-axis) as a rotation axis. The first lens module 2100 and the bracket 3200 can also rotate together with the guide member 3300 about the first optical axis (X-axis) as a rotation axis. The first optical axis (X-axis) can also be referred to as the first rotation axis.

[0074] The bracket 3200 can rotate about a third axis (Y-axis) that is perpendicular to both the first optical axis (X-axis) and the second optical axis (Z-axis). For example, the bracket 3200 can rotate relative to the guide member 3300 about the third axis (Y-axis). The first lens module 2100 can rotate together with the bracket 3200 about the third axis (Y-axis). The third axis (Y-axis) can also be referred to as the second axis of rotation.

[0075] A first driving section 4000 can be configured to rotate the reflection module 3000. The first driving section 4000 may include a first magnet 4100 and a first coil 4200. The guide member 3300 can rotate relative to the housing 1000 about a first optical axis (X-axis) as a rotation axis. Since the bracket 3200 and the first lens module 2100 can be mounted on the guide member 3300, the bracket 3200 and the first lens module 2100 can also rotate together with the guide member 3300 about the first optical axis (X-axis) as a rotation axis.

[0076] The first magnet 4100 can be mounted on the guide member 3300. As an example, the first magnet 4100 can be mounted on a surface of the guide member 3300. This surface of the guide member 3300 can be the surface of the guide member 3300 facing the housing 1000 in the direction of the first optical axis (X-axis). For example, this surface of the guide member 3300 can be the lower surface of the guide member 3300.

[0077] The first magnet 4100 may include two magnets spaced apart from each other. The two magnets may be tilted relative to each other in a plane perpendicular to the first optical axis (X-axis).

[0078] Each of the two magnets in the first magnet 4100 can be magnetized such that its surface facing the first coil 4200 can have both a first polarity P1 and a second polarity P2. The first polarity P1 and the second polarity P2 are opposite to each other, such that when the first polarity P1 is the N pole, the second polarity P2 is the S pole.

[0079] In an embodiment, one of the two magnets of the first magnet 4100 (hereinafter referred to as magnet 1-1) may have a surface facing the first coil 4200, the surface facing the first coil 4200 having a first polarity P1 and a second polarity P2 and a neutral region N1 formed between the first polarity P1 and the second polarity P2 (see [link to relevant documentation]). Figure 8 ).

[0080] The remaining one of the two magnets of the first magnet 4100 (hereinafter referred to as magnet 1-2) may have a surface facing the first coil 4200, the surface facing the first coil 4200 having a second polarity P2 and a first polarity P1 and a neutral region N1 formed between the second polarity P2 and the first polarity P1 (see...). Figure 8 Therefore, the polarity of magnet 1-2 is arranged in the opposite direction to that of magnet 1-1.

[0081] Magnets 1-1 and 1-2 can be configured such that the distance between them decreases in the negative direction (-Z-axis direction) of the second optical axis (Z-axis).

[0082] For example, the distance between the N pole (P1) of the surface of magnet 1-1 facing the first coil 4200 and the S pole (P2) of the surface of magnet 1-2 facing the first coil 4200 can be less than the distance between the S pole (P2) of the surface of magnet 1-1 facing the first coil 4200 and the N pole (P1) of the surface of magnet 1-2 facing the first coil 4200 (the reverse is also possible).

[0083] The first coil 4200 can be positioned facing the first magnet 4100. In an embodiment, the first coil 4200 can be positioned facing the first magnet 4100 in the direction of the first optical axis (X-axis).

[0084] The first coil 4200 is disposed on the substrate 9000, and the substrate 9000 is mounted on the housing 1000, such that the first magnet 4100 and the first coil 4200 face each other in the direction of the first optical axis (X-axis).

[0085] The housing 1000 may have a through hole penetrating the housing 1000 in the direction of the first optical axis (X-axis), and the first coil 4200 may be disposed in the through hole such that the first coil 4200 directly faces the first magnet 4100 in the direction of the first optical axis (X-axis).

[0086] The first coil 4200 may include two coils. The two coils may be tilted relative to each other in a plane perpendicular to the first optical axis (X-axis).

[0087] During jitter correction, the first magnet 4100 is a movable member mounted on the guide member 3300 and rotates together with the guide member 3300, and the first coil 4200 is a fixed member fixed to the substrate 9000.

[0088] When power is applied to the first drive section 4000, the first drive section 4000 can generate a driving force to rotate the guide member 3300 about the first optical axis (X-axis).

[0089] The first ball component B1 can be disposed between the guide component 3300 and the housing 1000.

[0090] The first ball component B1 may include a first ball BC forming the rotation axis of the guide component 3300 and a plurality of guide balls BG supporting the rotation of the guide component 3300.

[0091] The guide member 3300 can be supported at three points by a first ball BC and multiple guide balls BG.

[0092] A virtual line extending in the direction of the first optical axis (X-axis) of the first lens module 2100 can pass through the first sphere BC.

[0093] The attractive force can act between the guide member 3300 and the housing 1000. In one embodiment, the first traction yoke 4400 can be positioned facing the first magnet 4100 in the direction of the first optical axis (X-axis).

[0094] The first traction yoke 4400 may be disposed on the substrate 9000. For example, the first coil 4200 may be disposed on the inner or upper surface of the substrate 9000, and the first traction yoke 4400 may be disposed on the outer or lower surface of the substrate 9000.

[0095] The first magnet 4100 and the first traction yoke 4400 can generate an attractive force between each other. For example, the first traction yoke 4400 can be made of a magnetic material. The attractive force acts between the first magnet 4100 and the first traction yoke 4400 in the direction of the first optical axis (X-axis).

[0096] The first ball component B1 can be kept in contact with the guide component 3300 and the housing 1000 by the attraction generated between the first magnet 4100 and the first traction yoke 4400.

[0097] The first guide groove g1 and the second guide groove g2 can be formed on the surfaces of the guide member 3300 and the housing 1000 that face each other in the direction of the first optical axis (X-axis). The first ball BC can be disposed in the first guide groove g1, and a plurality of guide balls BG can be disposed in the second guide groove g2.

[0098] The first ball BC forms a three-point contact with the first guide groove g1 of the guide member 3300, and also forms a three-point contact with the first guide groove g1 of the housing 1000.

[0099] The first ball BC can be disposed between the first guide groove g1 of the guide member 3300 and the first guide groove g1 of the housing 1000 to form the rotation axis of the guide member 3300.

[0100] In an implementation, each of the plurality of guide balls BG may make point contact with the second guide groove g2 of the guide member 3300 and with the second guide groove g2 of the housing 1000.

[0101] In another embodiment, each of the plurality of guide balls BG may make two-point contact with the second guide groove g2 of the guide member 3300 and one-point contact with the second guide groove g2 of the housing 1000 (and vice versa).

[0102] A second drive section 5000 can be provided to rotate the bracket 3200 relative to the guide member 3300. The second drive section 5000 includes a second magnet 5100 and a second coil 5200. The bracket 3200 can be rotated about a third axis (Y-axis) via the second drive section 5000. Since the first lens module 2100 is disposed in the bracket 3200, the first lens module 2100 can be rotated together with the bracket 3200 about the third axis (Y-axis) via the second drive section 5000.

[0103] The second magnet 5100 can be mounted on the bracket 3200. As an example, the second magnet 5100 can be mounted on the side surface of the bracket 3200.

[0104] The second magnet 5100 can be magnetized such that the surface of the second magnet 5100 facing the second coil 5200 has both an N pole and a S pole. In an embodiment, the surface of the second magnet 5100 facing the second coil 5200 may have an N pole, a neutral region, and an S pole arranged sequentially in the direction of the first optical axis (X-axis).

[0105] The second magnet 5100 may have a shape having a length extending in the direction of the third axis (Y-axis). For example, the second magnet 5100 may be formed such that its length in the direction of the third axis (Y-axis) is longer than its length in the direction of the first optical axis (X-axis).

[0106] The second coil 5200 can be disposed on the substrate 9000, and the substrate 9000 can be mounted on the housing 1000, such that the second magnet 5100 and the second coil 5200 face each other in the direction of the second optical axis (Z axis).

[0107] The second coil 5200 may have a shape that extends in the direction of the third axis (Y-axis). For example, the second coil 5200 may be formed such that its length in the direction of the third axis (Y-axis) is longer than its length in the direction of the first optical axis (X-axis).

[0108] The housing 1000 may have a through hole penetrating the housing 1000 in the direction of the second optical axis (Z axis), and the second coil 5200 may be disposed in the through hole such that the second coil 5200 directly faces the second magnet 5100 in the direction of the second optical axis (Z axis).

[0109] During jitter correction, the second magnet 5100 is a movable component mounted on the bracket 3200 and rotating together with the bracket 3200, and the second coil 5200 is a fixed component fixed to the substrate 9000.

[0110] When power is applied to the second drive section 5000, the second drive section 5000 can generate a driving force to make the bracket 3200 rotate about the third axis (Y-axis) as a rotation axis.

[0111] The second ball component B2 can be disposed between the support 3200 and the guide component 3300. The second ball component B2 can be disposed between the support 3200 and the guide component 3300 to form the rotation axis of the support 3200.

[0112] The second spherical component B2 includes a plurality of spheres spaced apart from each other in the direction of the third axis (Y-axis).

[0113] When viewed in the direction of the third axis (Y-axis), a portion of the reflective surface of the reflective member 3100 can overlap with the second spherical member B2.

[0114] Virtual lines of multiple spheres extending through the second sphere member B2 in the direction of the third axis (Y-axis) can pass through the reflective surface of the reflective member 3100.

[0115] The attractive force can act between the support 3200 and the guide member 3300. In one embodiment, the first traction magnet 5300 can be disposed on one of the support 3200 and the guide member 3300, and the second traction yoke 5400 can be disposed on the other of the support 3200 and the guide member 3300. In another embodiment, the first traction magnet 5300 can be disposed on both the support 3200 and the guide member 3300.

[0116] A surface of the first traction magnet 5300 (e.g., the surface facing the second traction yoke 5400) can be magnetized to have an N pole, a neutral region, and an S pole arranged sequentially in the direction of the third axis (Y axis).

[0117] The first traction magnet 5300 and the second traction yoke 5400 can face each other in the direction of the second optical axis (Z axis).

[0118] The first traction magnet 5300 and the second traction yoke 5400 can generate an attractive force between each other. For example, the second traction yoke 5400 can be made of a magnetic material. The attractive force acts between the first traction magnet 5300 and the second traction yoke 5400 in the direction of the second optical axis (Z-axis).

[0119] The second ball component B2 can be kept in contact with the bracket 3200 and the guide component 3300 by the attraction generated between the first traction magnet 5300 and the second traction yoke 5400.

[0120] The third guide groove g3 can be formed in the surfaces of the support 3200 and the guide member 3300 that face each other in the direction of the second optical axis (Z axis).

[0121] The second ball component B2 can be disposed between the third guide groove g3 of the bracket 3200 and the third guide groove g3 of the guide component 3300 to form the rotation axis of the bracket 3200.

[0122] The reflective module 3000 may further include a stop 7100. The stop 7100 may be coupled to the guide member 3300 to cover at least a portion of the bracket 3200. For example, the stop 7100 may cover at least a portion of the upper surface of the bracket 3200. The stop 7100 and the bracket 3200 may be spaced apart from each other in the direction of the first optical axis (X-axis).

[0123] Since the stop 7100 is spaced apart from the bracket 3200, the bracket 3200 can be prevented from separating from the guide member 3300 due to external impact or other interference without interfering with the rotation of the bracket 3200.

[0124] A resilient buffer member 7200 can be connected to a stop member 7100. The buffer member 7200 can be disposed on any one or both of the two surfaces of the stop member 7100 facing the support 3200.

[0125] Figure 8 This is a diagram illustrating a first position sensing portion according to an embodiment of the present disclosure.

[0126] The camera module can detect the position of the guide member 3300. For this purpose, a first position sensing part 4500 is provided. The first position sensing part 4500 includes a first sensing magnet 4510 and a first position sensor 4520.

[0127] When the guide member 3300 rotates around the first optical axis (X-axis) as a rotation axis, the position of the guide member 3300 can be detected by the first position sensing part 4500.

[0128] The first sensing magnet 4510 may be disposed on a surface (e.g., the lower surface) of the guide member 3300. Furthermore, the first sensing magnet 4510 may be spaced apart from the first magnet 4100. For example, the first sensing magnet 4510 may be spaced apart from magnets 1-1 and 1-2 of the first magnet 4100.

[0129] In one embodiment, the first sensing magnet 4510 may be spaced apart from the first sphere BC in the direction of the second optical axis (Z axis).

[0130] The first sensing magnet 4510 can be magnetized such that a surface (e.g., the lower surface) can have both N poles and S poles. In an embodiment, a surface of the first sensing magnet 4510 can have N poles, a neutral region, and S poles arranged sequentially in the direction of a third axis (Y-axis).

[0131] A virtual line extending through the neutral region of the first sensing magnet 4510 in the direction of the second optical axis (Z-axis) can pass through the first sphere BC.

[0132] The N pole of the first sensing magnet 4510 can be closer to the N pole of magnet 1-1 instead of the S pole of magnet 1-1, and the S pole of the first sensing magnet 4510 can be closer to the S pole of magnet 1-2 instead of the N pole of magnet 1-2.

[0133] In other words, the first sensing magnet 4510 can be configured such that the N pole of the first sensing magnet 4510 is adjacent to the N pole of magnet 1-1, and the S pole of the first sensing magnet 4510 is adjacent to the S pole of magnet 1-2.

[0134] Since the camera module according to the embodiments of this disclosure includes a separate first sensing magnet 4510 for position sensing of the guide member 3300, the size of the first coil 4200 facing the first magnet 4100 can be increased. Therefore, the magnitude of the driving force generated by the first driving portion 4000 can be increased.

[0135] The first position sensor 4520 can be disposed at a location that detects position changes of the first sensing magnet 4510. In one embodiment, the first sensing magnet 4510 and the first position sensor 4520 can be disposed facing each other in the direction of the first optical axis (X-axis). In another embodiment, when viewed in the direction of the first optical axis (X-axis), the first sensing magnet 4510 and the first position sensor 4520 can be spaced apart from each other in the direction of the second optical axis (Z-axis).

[0136] The first position sensor 4520 can be located at a position spaced apart from the first coil 4200. The first position sensor 4520 can be a Hall sensor.

[0137] When power is applied to the first coil 4200, the position of the guide member 3300 detected by the first position sensor 4520 may exhibit errors due to Hall coupling caused by the magnetic field of the first coil 4200. However, since the camera module according to the embodiment of the present disclosure has a first position sensor 4520 spaced apart from the first coil 4200, the accuracy of position sensing of the guide member 3300 can be improved.

[0138] In one embodiment, the first position sensor 4520 may be spaced apart from the first ball BC in the direction of the second optical axis (Z axis).

[0139] The housing 1000 may have a through hole penetrating the housing 1000 in the direction of the first optical axis (X-axis), and a substrate 9000 covering the through hole may be disposed on the lower surface of the housing 1000. The first position sensor 4520 may be disposed in the through hole on the upper surface of the substrate 9000, such that the first position sensor 4520 directly faces the first sensing magnet 4510 in the direction of the first optical axis (X-axis).

[0140] Figure 9 This is a diagram illustrating a second position sensing portion according to an embodiment of the present disclosure.

[0141] The camera module can detect the position of the bracket 3200. For this purpose, a second position sensing part 5500 is provided. The second position sensing part 5500 includes a second sensing magnet 5510 and a second position sensor 5520.

[0142] When the bracket 3200 rotates around the third axis (Y-axis), the position of the bracket 3200 can be detected by the second position sensing part 5500.

[0143] The second sensing magnet 5510 can be disposed on the side surface of the bracket 3200. Furthermore, the second sensing magnet 5510 can be spaced apart from the second magnet 5100. For example, the second sensing magnet 5510 can be spaced apart from the second magnet 5100 in the direction of the first optical axis (X-axis).

[0144] The surface of the second sensing magnet 5510 may have a polarity opposite to that of the adjacent portion of the second magnet 5100.

[0145] In one embodiment, the surface of the second magnet 5100 may have an N pole, a neutral region, and an S pole arranged sequentially from top to bottom along the first optical axis (X-axis). In this case, the polarity of the surface of the second sensing magnet 5510 may vary depending on the placement of the second sensing magnet 5510.

[0146] For example, such as Figure 9 As shown, when the second sensing magnet 5510 is positioned below the second magnet 5100 in the direction of the first optical axis (X-axis), the surface of the second sensing magnet 5510 may have an N pole.

[0147] In another example, when the second sensing magnet 5510 is positioned above the second magnet 5100 in the direction of the first optical axis (X-axis), the surface of the second magnet 5100 may have an S pole.

[0148] Since the camera module according to the embodiments of this disclosure includes a separate second sensing magnet 5510 for position sensing of the bracket 3200, the size of the second coil 5200 facing the second magnet 5100 can be increased. Therefore, the magnitude of the driving force generated by the second driving portion 5000 can be increased.

[0149] The second position sensor 5520 can be set at the location where the position change of the second sensing magnet 5510 is detected.

[0150] In one embodiment, the second position sensor 5520 may be configured such that at least a portion of the second position sensor 5520 faces the space between the second magnet 5100 and the second sensing magnet 5510 in the direction of the first optical axis (X-axis). The space between the second magnet 5100 and the second sensing magnet 5510 can function as a neutral region because it is positioned between different polarities.

[0151] The second position sensor 5520 may be spaced apart from the second coil 5200. For example, the second position sensor 5520 may be spaced apart from the second coil 5200 in the direction of the first optical axis (X-axis).

[0152] The second position sensor 5520 can be a Hall sensor.

[0153] Magnetic field lines can pass through the upper part of the second coil 5200 in one direction along the first optical axis (X-axis), and magnetic field lines can pass through the lower part of the second coil 5200 in another direction opposite to the first optical axis (X-axis).

[0154] Furthermore, magnetic field lines can pass through the upper part of the second position sensor 5520 (e.g., the portion of the second position sensor 5520 adjacent to the lower part of the second coil 5200) in the direction of the first optical axis (X-axis) along the other direction, and magnetic field lines can also pass through the lower part of the second position sensor 5520 in the direction of the first optical axis (X-axis) along the other direction.

[0155] When power is applied to the second coil 5200, the position of the bracket 3200 detected by the second position sensor 5520 may exhibit errors due to Hall coupling caused by the magnetic field of the second coil 5200. However, since the camera module according to the embodiment of this disclosure has a second position sensor 5520 spaced apart from the second coil 5200, the accuracy of position sensing of the guide member 3300 can be improved.

[0156] Figure 10 This is a diagram illustrating a first modified example of the second position sensing portion according to an embodiment of the present disclosure.

[0157] exist Figure 10 In some embodiments, the second position sensing portion 5500 may include a second position sensor 5520, and may not include a second position sensor 5520. Figure 9 The first position sensing magnet 5510 in the embodiment is a separate sensing magnet.

[0158] like Figure 10 As shown, a portion of the second magnet 5100 of the second drive portion 5000 can be used to generate driving force, and another portion of the second magnet 5100 can be used for position sensing.

[0159] The surface of the second magnet 5100 may have two identical polarities (e.g., a first polarity) and one opposite polarity (e.g., a second polarity). The second coil 5200 may face either of the two first polarities and the second polarity. Furthermore, the second position sensor 5520 may be configured such that at least a portion of it is positioned between the remaining one of the two first polarities and the second polarity.

[0160] In one embodiment, the surface of the second magnet 5100 may have N poles, a neutral region, an S pole, another neutral region, and another N pole arranged sequentially from top to bottom along the first optical axis (X-axis). The areas of the uppermost and lowermost poles along the first optical axis (X-axis) can vary depending on the location of the second position sensor 5520.

[0161] For example, when the second position sensor 5520 is positioned below the second magnet 5100 in the direction of the first optical axis (X-axis), the area of ​​the lowest polarity of the second magnet 5100 in the direction of the first optical axis (X-axis) can be smaller than the area of ​​the adjacent opposite polarity.

[0162] When the second position sensor 5520 is positioned above the second magnet 5100 in the first optical axis (X-axis) direction, the area of ​​the uppermost polarity of the second magnet 5100 in the first optical axis (X-axis) direction can be smaller than the area of ​​the adjacent opposite polarity.

[0163] exist Figure 10 In this embodiment, the surface area of ​​the second magnet 5100 facing the second coil 5200 can be relatively large, thereby increasing the magnitude of the driving force generated by the second driving part 5000.

[0164] The second position sensor 5520 is spaced apart from the second coil 5200 in the direction of the first optical axis (X-axis), and at least a portion of the second position sensor 5520 can be configured to face the neutral region of the second magnet 5100.

[0165] exist Figure 10 In this embodiment, since the second position sensor 5520 is spaced apart from the second coil 5200, the accuracy of position sensing of the bracket 3200 can be improved.

[0166] Figure 11 This is a diagram illustrating a second modified example of the second position sensing portion according to an embodiment of the present disclosure.

[0167] exist Figure 11 In one embodiment, the second position sensing portion 5500 may include a second sensing magnet 5510 and a second position sensor 5520.

[0168] The second sensing magnet 5510 may be spaced apart from the second magnet 5100. For example, the second sensing magnet 5510 may be spaced apart from the second magnet 5100 in the direction of the first optical axis (X-axis).

[0169] The surface of the second sensing magnet 5510 may have both an N pole and a S pole. In an embodiment, the surface of the second sensing magnet 5510 may have an S pole, a neutral region, and an N pole arranged sequentially on a first optical axis (X-axis).

[0170] The polarity of a portion of the surface of the second sensing magnet 5510 may be the same as the polarity of the surface of the second magnet 5100, which is disposed adjacent to that portion of the second sensing magnet 5510. Therefore, the polarity of the surface of the second sensing magnet 5510 can be configured differently depending on the arrangement of the polarity of one surface of the second magnet 5100.

[0171] In one embodiment, the surface of the second magnet 5100 may have an N pole, a neutral region, and an S pole arranged sequentially from top to bottom along the first optical axis (X-axis). In this case, the surface of the second sensing magnet 5510 may have an S pole, a neutral region, and an N pole arranged sequentially from top to bottom along the first optical axis (X-axis).

[0172] exist Figure 11 In this embodiment, since a separate second sensing magnet 5510 is included for position sensing of the bracket 3200, the size of the second coil 5200 facing the second magnet 5100 can be increased. Therefore, the magnitude of the driving force generated by the second driving portion 5000 can be increased.

[0173] The second position sensor 5520 may be disposed facing the second sensing magnet 5510. In an embodiment, the second position sensor 5520 may be configured such that at least a portion of the second position sensor 5520 faces the neutral region of the surface of the second sensing magnet 5510.

[0174] The second position sensor 5520 may be spaced apart from the second coil 5200. For example, the second position sensor 5520 may be spaced apart from the second coil 5200 in the direction of the first optical axis (X-axis).

[0175] The second position sensor 5520 can be a Hall sensor.

[0176] exist Figure 11 In this embodiment, since the second position sensor 5520 is spaced apart from the second coil 5200, the accuracy of position sensing of the bracket 3200 can be improved.

[0177] Figure 12 and Figure 13 This is a perspective view showing a second lens module separate from the camera module according to an embodiment of the present disclosure.

[0178] Reference Figure 12 and Figure 13 The second lens module 2200 can be positioned between the reflection module 3000 and the image sensor module 8000.

[0179] The second lens module 2200 can be moved in the direction of the second optical axis (Z axis) to adjust the focus.

[0180] In one embodiment, the second lens module 2200 includes a second lens barrel 2210 and a support portion 2220. Multiple lenses can be disposed in the second lens barrel 2210, and the second lens barrel 2210 can be connected to the support portion 2220.

[0181] The camera module may include a third drive section 6000 to move the second lens module 2200 in the direction of the second optical axis (Z-axis).

[0182] The third drive section 6000 includes a third magnet 6100 and a third coil 6200. The third magnet 6100 and the third coil 6200 can be arranged to face each other in a direction perpendicular to the second optical axis (Z-axis).

[0183] The third magnet 6100 is mounted on the second lens module 2200. For example, the third magnet 6100 may be disposed on the side surface of the second lens module 2200 (e.g., the side surface of the support portion 2220).

[0184] In one embodiment, the second lens module 2200 includes a side surface and another side surface spaced apart from each other in the direction of the third axis (Y-axis). The third magnet 6100 may be disposed on one side surface of the second lens module 2200.

[0185] The third magnet 6100 can be magnetized such that the surface of the third magnet 6100 facing the third coil 6200 has both N poles and S poles. For example, the surface of the third magnet 6100 facing the third coil 6200 can have N poles, a neutral region, and S poles arranged sequentially in the direction of the second optical axis (Z axis).

[0186] The third coil 6200 is configured to face the third magnet 6100. For example, the third coil 6200 may be configured to face the third magnet 6100 in a direction perpendicular to the second optical axis (Z-axis) (e.g., in the third axis (Y-axis) direction).

[0187] The third coil 6200 is disposed on the substrate 9000, and the substrate 9000 is mounted on the housing 1000, such that the third magnet 6100 and the third coil 6200 face each other in the direction of the third axis (Y axis).

[0188] The housing 1000 may have a through hole penetrating the housing 1000 in the third axis (Y-axis) direction, and the third coil 6200 disposed on the substrate 9000 may directly face the third magnet 6100 through the through hole in the third axis (Y-axis) direction.

[0189] During focus adjustment, the third magnet 6100 is a moving member mounted on the second lens module 2200 and moving together with the second lens module 2200 in the direction of the second optical axis (Z axis), and the third coil 6200 is a fixed member fixed to the substrate 9000.

[0190] When power is applied to the third coil 6200, the second lens module 2200 can move in the direction of the second optical axis (Z-axis) by the electromagnetic force generated between the third magnet 6100 and the third coil 6200.

[0191] The third spherical component B3 is disposed between the second lens module 2200 and the housing 1000, and the second lens module 2200 can be guided by the third spherical component B3 to move in the direction of the second optical axis (Z-axis). The third spherical component B3 includes a plurality of spheres.

[0192] The second traction magnet 6300 can be disposed on the lower surface of the second lens module 2200, and the third traction yoke 6400 can be disposed on the inner bottom surface of the housing 1000. In another embodiment, the second traction magnet 6300 can be disposed on both the second lens module 2200 and the housing 1000.

[0193] The second traction magnet 6300 can be positioned closer to one side surface of the second lens module 2200 in the third axis (Y-axis) direction. That is, the second traction magnet 6300 can be positioned closer to one side surface of the second lens module 2200 in the third axis (Y-axis) direction, rather than the other side surface of the second lens module 2200. In other words, the second traction magnet 6300 can be positioned between one side surface of the second lens module 2200 and the second optical axis (Z-axis) in the third axis (Y-axis) direction.

[0194] The second traction magnet 6300 and the third traction yoke 6400 can be arranged to face each other in the direction of the first optical axis (X-axis).

[0195] The second traction magnet 6300 and the third traction yoke 6400 can generate an attractive force between them. For example, an attractive force is generated between the second traction magnet 6300 and the third traction yoke 6400 in the direction of the first optical axis (X-axis).

[0196] Due to the attraction generated between the second traction magnet 6300 and the third traction yoke 6400, the third ball component B3 can remain in contact with the second lens module 2200 and the housing 1000.

[0197] Some of the spheres in the third sphere component B3 may be positioned closer to one side surface of the second lens module 2200 than the other side surface of the second lens module 2200 in the third axis (Y-axis) direction, and the remaining spheres in the third sphere component B3 may be positioned closer to the other side surface of the second lens module 2200 than one side surface of the second lens module 2200 in the third axis (Y-axis) direction.

[0198] The number of balls in the third spherical member B3 disposed between one side surface of the second lens module 2200 and the second optical axis (Z-axis) can be greater than the number of balls in the third spherical member B3 disposed between the other side surface of the second lens module 2200 and the second optical axis (Z-axis).

[0199] In one embodiment, the third spherical component B3 may include three spheres. Two of the three spheres may be disposed between one side surface of the second lens module 2200 and the second optical axis (Z-axis), and the remaining one of the three spheres may be disposed between the other side surface of the second lens module 2200 and the second optical axis (Z-axis).

[0200] Two spheres positioned between a side surface of the second lens module 2200 and the second optical axis (Z-axis) can be spaced apart in the direction of the second optical axis (Z-axis).

[0201] The fourth guide groove g4 and the fifth guide groove g5 can be formed in the surfaces of the second lens module 2200 and the housing 1000 that face each other. For example, the fourth guide groove g4 can be formed in one side of the surfaces of the second lens module 2200 and the housing 1000 that face each other, and the fifth guide groove g5 can be formed in the other side of the surfaces of the second lens module 2200 and the housing 1000 that face each other.

[0202] The fourth guide groove g4 and the fifth guide groove g5 can be spaced apart from each other in the direction of the third axis (Y-axis).

[0203] The fourth guide groove g4 and the fifth guide groove g5 can extend in a direction parallel to the second optical axis (Z axis).

[0204] Some of the balls in the third ball component B3 are disposed in the fourth guide groove g4, and the remaining balls in the third ball component B3 are disposed in the fifth guide groove g5.

[0205] The number of contact points between some of the balls in the third ball component B3 and the fourth guide groove g4 is greater than the number of contact points between the remaining balls in the third ball component B3 and the fifth guide groove g5.

[0206] The fourth guide groove g4 is positioned closer to the second lens module 2200 than the fifth guide groove g5, and a side surface of the third magnet 6100 is disposed thereon.

[0207] The second traction magnet 6300 can be positioned closer to the fourth guide slot g4 instead of the fifth guide slot g5.

[0208] In this implementation, the camera module can detect the position of the second lens module 2200. For this purpose, a third position sensor 6500 is provided. The third position sensor 6500 can be located at the position of the third magnet 6100 facing the third drive section 6000 (e.g., in the direction facing the third axis (Y-axis)).

[0209] Therefore, when the second lens module 2200 moves in the direction of the second optical axis (Z axis), the position of the second lens module 2200 can be detected by the third position sensor 6500.

[0210] The third position sensor 6500 can be a Hall sensor.

[0211] Although not shown in the accompanying drawings, at least one lens (hereinafter referred to as the corrective lens) may be connected to the reflective member 3100 of the reflective module 3000. The corrective lens may have positive refractive power.

[0212] In one embodiment, the exit surface of the reflective member 3100 of the reflective module 3000 and the object side of the corrective lens can be connected to each other.

[0213] Therefore, when the reflection module 3000 rotates, the correction lens can also rotate together with the reflection module 3000.

[0214] As in the embodiments of this disclosure, when a corrective lens with positive refractive power is disposed behind the reflective member 3100 of the reflective module 3000, errors in the optical path that occur during jitter correction can be compensated, and high-quality images can be captured.

[0215] While this disclosure includes specific examples, it will be apparent upon understanding this disclosure that various changes in form and detail may be made to these examples without departing from the spirit and scope of the claims and their equivalents. The description of features or aspects in each example should be considered applicable to similar features or aspects in other examples. Suitable results may still be achieved if the described techniques are performed in a different order, and / or if components in the described system, architecture, device, or circuit are combined in different ways and / or replaced or supplemented by other components or their equivalents.
