Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of priority from Korean Patent Application No. 10-2021-0026523 filed in the Korean Intellectual Property Office on February 26, 2021, the disclosure of which is incorporated herein in its entirety by reference for all purposes. Technical Field

[0003] The following description relates to a camera module including an optical path changing unit. Background Art

[0004] A camera module for telephoto or long focal length imaging may be formed to have a relatively large size. For example, the size or length of the telephoto camera module may be greater than the size and length of the wide-angle camera module. A camera module for telephoto imaging or long focal length imaging may include a plurality of bodies. For example, the telephoto camera module may include a first body accommodating a lens and a second body including an image sensor. The first body and the second body of the camera module may be coupled together by a fastening unit. For example, in a camera module mounted on a portable terminal, in consideration of the lightweight and assembly convenience of the camera module, an adhesive may be used to couple the first body and the second body together. However, since the use of an adhesive to couple between the first body and the second body may cause an inflow of the adhesive, the performance of the camera module may be impaired.

[0040] Throughout the drawings and detailed description, the same reference numerals will be understood to refer to the same elements, features, and structures. For purposes of clarity, illustration, and convenience, the drawings may not be drawn to scale, and the relative sizes, proportions, and depictions of elements in the drawings may be exaggerated. DETAILED DESCRIPTION

[0041] The following specific embodiments are provided to help the reader obtain a comprehensive understanding of the method, device and / or system described herein. However, various changes, modifications and equivalents of the method, device and / or system described herein will be apparent after understanding the disclosure of the application. For example, except for the operations that must occur in a specific order, the order of the operations described herein is merely an example, and is not limited to the order set forth in this article, but changes that will be apparent after obtaining an understanding of the disclosure of the application can be made. In addition, for greater clarity and brevity, the description of features known in the art may be omitted.

[0042] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways to implement the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0043] It should be noted herein that the use of the term "may" with respect to an embodiment or example (e.g., with respect to what an embodiment or example may include or implement) means that there is at least one embodiment or example that includes or implements such feature, rather than all embodiments and examples being limited thereto.

[0044] Throughout the specification, when an element such as a layer, region, or substrate is described as being "on," "connected to," or "coupled to" another element, the element may be directly "on," "connected to," or "coupled to" another 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 coupled to" another element, there are no other elements between the element and the other element. Furthermore, hereinafter, a transverse section means a cut surface in a direction intersecting the optical axis, and a longitudinal section means a cut surface in a direction parallel to the optical axis.

[0045] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0046] Although the terms "first", "second" and "third" may be used herein to describe various members, components, regions, layers or parts, these members, components, regions, layers or parts are not limited by these terms. More specifically, these terms are only used to distinguish one member, component, region, layer or part from another member, component, region, layer or part. Therefore, without departing from the teachings of the examples described herein, the first member, first component, first region, first layer or first part mentioned in the examples may also be referred to as the second member, second component, second region, second layer or second part.

[0047] Spatially relative terms such as "above", "higher", "below", and "lower" may be used herein for descriptive convenience to describe the relationship of one element relative to another element as shown in the accompanying drawings. In addition to covering the orientations depicted in the accompanying drawings, these spatially relative terms are intended to also cover different orientations of the device in use or operation. For example, if the device in the accompanying drawings is flipped, an element described as being "above" or "higher" relative to another element will be "below" or "lower" relative to the other element. Therefore, depending on the spatial orientation of the device, the term "above" covers both "above" and "below" orientations. The device may also be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.

[0048] The terms used herein are only used to describe various examples and are not intended to limit the present disclosure. Unless the context clearly indicates otherwise, the articles "a", "an" and "the" are intended to include plural forms as well. The words "include", "comprise" and "have" illustrate the presence of stated features, numbers, operations, components, elements and / or combinations thereof, but do not exclude the presence or addition of one or more other features, numbers, operations, components, elements and / or combinations thereof.

[0049] Due to manufacturing techniques and / or tolerances, the shapes shown in the drawings may vary. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include shape variations that occur during manufacturing.

[0050] The features of the examples described herein can be combined in various ways, which will be apparent after obtaining an understanding of the disclosure of the present application. In addition, although the examples described herein have multiple configurations, it will be apparent after obtaining an understanding of the disclosure of the present application that other configurations are also possible.

[0051] The camera module described herein may be installed on a portable electronic product. For example, the camera module may be installed on a portable phone, a laptop computer, etc. However, the scope of use of the camera module according to the examples disclosed herein is not limited to the above-mentioned electronic devices. For example, the camera module may be installed in any electronic device that requires screen shooting and video shooting (such as motion detection, image shooting, facial recognition, iris recognition, virtual reality implementation, augmented reality implementation, etc.).

[0052] The camera module disclosed herein may be configured to have a long focal length. For example, the camera module may be configured to accommodate a telephoto optical imaging system. The camera module may be configured to be separable into multiple bodies for ease of manufacturing and assembly. For example, the camera module may include a first body and a second body, wherein the first body has a lens module and the second body has an image sensor, so that an optical axis alignment operation between the lens module and the image sensor is possible. However, the separable configuration of the camera module is not limited to the first body and the second body. For example, the camera module may also be configured in the form of a first body including an optical path changing unit, a second body including a lens module, and a third body including an image sensor.

[0053] The camera module may be configured to be mounted on a thin portable terminal. For example, a cross-section of the camera module may be formed to have a substantially rectangular shape. As another example, a cross-section of the first body and a cross-section of the second body may be formed to have a substantially rectangular shape. In more detail, in the cross-sections of the first body and the second body, a length in a horizontal direction may be greater than a length in a vertical direction. In addition, the camera module may include a lens or a lens module in which a length in a first direction intersecting the optical axis and a length in a second direction intersecting the optical axis are different.

[0054] The camera module may be configured to facilitate the connection or combination between the separated bodies. For example, the camera module may include a protrusion for forming a combination space between the first body and the second body. The combination space may be formed differently depending on the longitudinal direction of the body. For example, the size of the combination space in the lateral direction of the first body and the second body may be wider than the size of the combination space in the longitudinal direction of the first body and the second body. This configuration is advantageous for thinning the camera module because the vertical height of the camera module can be significantly reduced.

[0055] The first body may be configured to receive or include a lens module and a first optical path changing unit. For example, a space for accommodating the lens module and the first optical path changing unit may be formed in the first body. The first body may include a first connecting portion configured to be connected to the second body. For example, a first connecting portion may be formed in a portion of the first body facing the second body. A first window may be formed in the first connecting portion. The first window may enable light to move from the first body toward the second body. For example, light refracted by the lens module may be projected in the direction of the second body through the first window. The first connecting portion may be formed to have different lengths in the horizontal direction and the vertical direction. For example, the length of the first connecting portion in a first direction intersecting with the optical axis passing through the first window may be configured to be different from the length of the first connecting portion in a second direction intersecting with the optical axis and the first direction.

[0056] The lens module may include a lens barrel and one or more lenses. For example, the lens module may include a lens barrel and four or more lenses accommodated in the lens barrel. The lens module may include a lens configured in such a manner that a length in a first direction intersecting the optical axis and a length in a second direction intersecting the optical axis and the first direction are different. For example, a lens disposed in the frontmost position in the lens module may be configured such that a length in a first direction intersecting the optical axis and a length in a second direction intersecting the optical axis and the first direction are different from each other.

[0057] The first optical path changing unit is configured to convert the path of light incident in the camera module. For example, the first optical path changing unit may refract or reflect the path of light incident in the height direction of the camera module in the longitudinal direction of the camera module. The first optical path changing unit may be disposed on one side of the lens module. For example, the first optical path changing unit may be disposed on the object side of the lens module.

[0058] The second body may be configured to include an image sensor. For example, the second body may accommodate a substrate on which an image sensor is mounted or may be connected to a substrate on which an image sensor is mounted. The second body may include a second connecting portion configured to be connected to the first body. For example, a second connecting portion may be formed in a portion of the second body facing the first body. A second window may be formed in the second connecting portion. The second window may be formed to have a size substantially the same as or similar to that of the first window and may be configured to face the first window. The second connecting portion may be formed to have different lengths in the horizontal direction and the vertical direction. In detail, the distance from the first side of the second window to the first side of the second connecting portion parallel to the first side of the second window may be different from the distance from the second side of the second window adjacent to the first side of the second window to the second side of the second connecting portion parallel to the second side of the second window.

[0059] The second body may include a configuration for substantially contacting the first body. For example, a protrusion may be formed on the second coupling portion of the second body. The protrusion may be configured to contact the first coupling portion of the first body. For example, the protrusion may be formed to extend in a direction from the second coupling portion to the first coupling portion. The protrusion may be configured to form a space between the first body and the second body. For example, the cross-sectional area of ​​the protrusion may be smaller than the cross-sectional area of ​​the first coupling portion and the cross-sectional area of ​​the second coupling portion. The protrusion may be formed at the edge of the second window. For example, the protrusion may be formed along the four sides of the second window. However, the protrusion does not have to be formed on each of the four sides of the second window. For example, the protrusion may be formed only on two or three sides of the second window.

[0060] The second body may also include components other than the image sensor and the substrate. For example, the second body may also include a filter component. The filter component may be disposed on the second window. The filter component may be configured to block light of a specific wavelength. For example, the filter component may be configured to block infrared rays. However, the light blocked by the filter component is not limited to infrared rays. The filter component may be formed to have a shape similar to that of the second window. For example, the filter component may be formed in a rectangular shape. For example, the length of a first side of the filter component may be greater than the length of a second side of the filter component intersecting with the first side. The filter component may be arranged to be surrounded by a protrusion. For example, a protrusion may be formed along the edge of the filter component to close at least three sides of the filter component.

[0061] The camera module may further include a form of an adhesive member for coupling the first body and the second body to each other. The adhesive member may be formed in an adhesive space formed between the first body and the second body.

[0062] Figure 1 is a partially exploded perspective view of a camera module according to an example.

[0063] refer to Figure 1 , the camera module 10 according to the example may include a first body 100 and a second body 200. However, the configuration of the camera module 10 is not limited to the first body 100 and the second body 200. For example, the camera module 10 may further include a substrate configured to be coupled to the second body 200.

[0064] The first body 100 may be configured to be coupled or combined to the second body 200. For example, the first coupling portion 120 may be formed on one side or one end of the first body 100. The first coupling portion 120 may be formed to have a shape substantially the same as or similar to a cross-section of the first body 100. However, the shape of the first coupling portion 120 is not limited to the cross-sectional shape of the first body 100. A first window 110 may be formed in the first coupling portion 120. The first window 110 may serve as a passage through which light incident into the first body 100 is projected onto the second body 200.

[0065] The first body 100 may be configured to enable the camera module 10 to be thinned. For example, a length L2 of the first body 100 in the height direction may be smaller than a length L1 of the first body 100 in the width direction. The first body 100 may be configured to accommodate a long focus optical imaging system (e.g., a telephoto optical imaging system). For example, a length L3 of the first body 100 in the direction of the optical axis C2 may have a relatively large size (e.g., twice or more the size of L1).

[0066] The first body 100 may include a configuration for refracting light reflected from an object. For example, the first body 100 may include a lens module 300. However, the configuration of the first body 100 is not limited to the lens module 300. For example, the first body 100 may further include a first optical path changing unit 512.

[0067] The first optical path changing unit 512 may be configured to convert an optical path of light incident in the camera module 10. For example, the first optical path changing unit 512 may refract or reflect a path of light incident along the optical axis C1 in the direction of the optical axis C2. The first optical path changing unit 512 may be disposed on one side of the lens module 300. For example, the first optical path changing unit 512 may be disposed on the object side of the lens module 300. The first optical path changing unit 512 may have a form capable of reflecting or refracting light. For example, the first optical path changing unit 512 may be a prism or a reflector.

[0068] Next, we will refer to Figure 2 The lens module 300 included in the first body 100 is described.

[0069] refer to Figure 2 , the lens module 300 may include one or more lenses 310. For example, the lens module 300 may include four or more lenses. However, the number of lenses included in the lens module 300 is not limited to four. For example, the lens module 300 may include 3 or less lenses, or 5 or more lenses.

[0070] The lens module 300 may be configured to have different lengths in a first direction and a second direction intersecting the optical axis C2. For example, a length LMx of the lens module 300 in the first direction may be greater than a length LMy of the lens module 300 in the second direction.

[0071] The lens module 300 may include lenses 310 having different lengths in a first direction and a second direction intersecting the optical axis C2. For example, one or more lenses 310 included in the lens module 300 may have a length Lx in the first direction intersecting the optical axis C2 and a length Ly in the second direction intersecting the optical axis C2, and the length Lx and the length Ly are different from each other, such as Figure 2 However, not all lenses included in the lens module 300 are formed in the form of one or more lenses 310. For example, some lenses 320 included in the lens module 300 may have a circular shape centered on the optical axis C2, such as Figure 2 shown.

[0072] Will refer to it again Figure 1 The second body 200 of the camera module 10 is described.

[0073] like Figure 1 As shown, the second body 200 may be configured to be coupled or combined to the first body 100. For example, the second coupling portion 220 may be formed on one side or one end of the second body 200. The second coupling portion 220 may be formed to have a shape substantially the same as or similar to the cross-section of the second body 200. However, the shape of the second coupling portion 220 is not limited to the cross-sectional shape of the second body 200. A second window 210 may be formed in the second coupling portion 220. The second window 210 may serve as a passage through which light projected from the first window 110 of the first body 100 is incident into the interior of the second body 200.

[0074] The second body 200 may be configured to enable thinning of the camera module 10. For example, a length L5 of the second body 200 in the height direction may be smaller than a length L4 of the second body 200 in the width direction.

[0075] The second body 200 may include a configuration for forming an image of light reflected from an object. For example, the second body 200 may include an image sensor 610. However, the configuration of the second body 200 is not limited to the image sensor 610. For example, the second body 200 may further include a substrate 600 on which the image sensor 610 is mounted.

[0076] The camera module 10 may further include a configuration capable of forming a separation space or an adhesion space between the first body 100 and the second body 200. For example, the camera module 10 may further include a protrusion 230 formed on the second body 200. The protrusion 230 may be formed at an edge of the second window 210. For example, the protrusion 230 may be formed to surround four sides of the second window 210. The protrusion 230 may be formed to have a predetermined height h toward the first body 100. The height h of the protrusion 230 may be increased or decreased as needed.

[0077] Next, we will refer to Figure 3A Exemplary shapes of the first coupling portion 120 of the first body 100 and the second coupling portion 220 of the second body 200 are described in more detail.

[0078] The first and second coupling portions 120 and 220 may be formed on the first and second bodies 100 and 200, respectively. For example, the first coupling portion 120 may be formed on one side or one end of the first body 100, and the second coupling portion 220 may be formed on one side or one end of the second body 200.

[0079] The first coupling portion 120 and the second coupling portion 220 may be configured to face each other. For example, in a coupled state of the first body 100 and the second body 200, the first coupling portion 120 and the second coupling portion 220 may be configured to face each other at a predetermined distance. A configuration for enabling light to be projected or incident may be formed in the first coupling portion 120 and the second coupling portion 220. For example, a first window 110 and a second window 210 may be formed in the first coupling portion 120 and the second coupling portion 220, respectively.

[0080] The first coupling portion 120 and the second coupling portion 220 may be configured to have different horizontal and vertical lengths. For example, the lateral length FBx of the first coupling portion 120 may be greater than the longitudinal length FBy, and the lateral length SBx of the second coupling portion 220 may be greater than the longitudinal length SBy.

[0081] The size or area of ​​the first coupling portion 120 and the second coupling portion 220 may be substantially the same or similar. For example, the lateral length FBx of the first coupling portion 120 may be substantially the same or similar to the lateral length SBx of the second coupling portion 220, and the longitudinal length FBy of the first coupling portion 120 may be substantially the same or similar to the longitudinal length SBy of the second coupling portion 220. However, the size or area of ​​the first coupling portion 120 and the second coupling portion 220 need not be the same or similar. For example, the size or area of ​​the first coupling portion 120 may be greater than the size or area of ​​the second coupling portion 220.

[0082] The first coupling portion 120 and the second coupling portion 220 may have different areas or sizes according to the first direction and the second direction intersecting the optical axis C2. For example, a distance D1y from the first side 110a of the first window 110 to a first side 120a of the first coupling portion 120 adjacent to the first side 110a may be different from a distance D1x from the second side 110b of the first window 110 to a second side 120b of the first coupling portion 120 adjacent to the second side 110b. As another example, a distance D2y from the first side 210a of the second window 210 to a first side 220a of the second coupling portion 220 adjacent to the first side 210a may be different from a distance D2x from the second side 210b of the second window 210 to a second side 220b of the second coupling portion 220 adjacent to the second side 210b.

[0083] An adhesive member may be applied or formed on the first coupling portion 120 and the second coupling portion 220. However, in the case where the adhesive member is directly applied to the first coupling portion 120 and the second coupling portion 220, the adhesive member may penetrate into the interior of the first body 100 through the first window 110 and may contaminate the lens of the lens module, or the adhesive member may penetrate into the interior of the second body 200 through the second window 210 and may contaminate the image sensor 610. Therefore, the camera module 10 further includes a configuration for solving the above-mentioned problems. For example, the camera module 10 may further include a protrusion 230 formed on the second body 200.

[0084] The protrusion 230 is configured to form a separation space or an adhesive space between the first coupling portion 120 and the second coupling portion 220. In addition, the protrusion 230 may be formed along the edge of the second window 210 to block the adhesive member from penetrating through the second window 210. In addition, the protrusion 230 is configured to surround the edge of the first window 110 in a coupled state between the first body 100 and the second body 200, and may also prevent the adhesive member from penetrating through the first window 110.

[0085] The protrusion 230 may form a space in which an adhesive member may be filled or formed between the first body 100 and the second body 200. For example, an adhesive member may be formed in the first coupling portion 120 and the second coupling portion 220 in an area (hatched portion) formed outside the protrusion 230.

[0086] The protrusion 230 may be formed to have a predetermined thickness (PTx, PTy). Regardless of the horizontal direction and the vertical direction of the second body 200, the thickness PTx and PTy of the protrusion 230 may be constant. For example, the horizontal thickness PTx of the protrusion 230 and the longitudinal thickness PTy of the protrusion 230 may be substantially the same. However, the horizontal thickness PTx of the protrusion 230 and the longitudinal thickness PTy of the protrusion 230 are not necessarily the same. For example, the horizontal thickness PTx of the protrusion 230 may be thinner than the longitudinal thickness PTy, so that sufficient bonding space can be formed outside the protrusion 230.

[0087] Reference Figure 3B and Figure 3C The second bodies 200 - 1 and 200 - 2 according to other examples are described.

[0088] First, refer to Figure 3B The second body 200 - 1 is described.

[0089] refer to Figure 3B , the second body 200-1 may be configured to limit a space in which an adhesive member may be formed. In more detail, an area (hatched portion) in which an adhesive member may be formed may be formed only between the second side 220b of the second coupling portion 220 and the second side 230b of the protrusion 230. In the second body 200-1 according to the first modified form, since it is not necessary to form a space in which an adhesive member may be formed between the first side 220a of the second coupling portion 220 and the first side 230a of the protrusion 230, the height SBy of the second body 200-1 may be reduced.

[0090] Next, we will refer to Figure 3C The second body 200 - 2 is described.

[0091] The second body 200-2 may further include a filter member 700 disposed on the second window 210. The filter member 700 may be formed to be larger than the second window 210. Therefore, the opening of the second window 210 may be completely blocked by the filter member 700. The filter member 700 may block the inflow of impurities or block the transmission of light of a specific wavelength. For example, the filter member 700 may be configured to block the transmission of infrared rays.

[0092] The second body 200-2 may be different from the above-described second bodies 200 and 200-1 in the shape of the protrusion 230-2. For example, the protrusion 230-2 may be formed to surround three sides of the second window 210 or three sides of the filter member 700. In detail, the protrusion 230-2 may not be formed on the first side 710 of the filter member 700.

[0093] In the second body 200-2, an adhesive member may be formed on the outside of the protrusion 230-2 and the outside of the filter member 700. In detail, the adhesive member may be filled or injected into a space (hatched portion) formed between the first side 220a of the second coupling portion 220 and the first side 710 of the filter member 700 and between the second side 220b of the second coupling portion 220 and the second side 230b of the protrusion 230-2.

[0094] In the second body 200-2, the protrusion 230-2 formed between the first side 220a of the second coupling portion 220 and the first side 710 of the filter member 700 may be omitted. Therefore, the height SBy of the second body 200-2 may be reduced. In addition, in the second body 200-2, since the adhesive member may fill the space between the first side 220a of the second coupling portion 220 and the first side 710 of the filter member 700, the bonding force between the first body 100 and the second body 200-2 may be improved.

[0095] Reference Figures 4 to 5B A coupling form of the camera module 10 according to an example is described.

[0096] The camera module 10 may include a first body 100 and a second body 200. The first body 100 and the second body 200 may be disposed in a direction intersecting the optical axis C1. The first body 100 and the second body 200 may be connected. For example, the first body 100 and the second body 200 may be firmly coupled together by an adhesive member 800.

[0097] A space in which the adhesive member 800 may be filled or injected may be formed between the first body 100 and the second body 200. For example, a relatively large space may be formed between the first coupling portion 120 of the first body 100 and the second coupling portion 220 of the second body 200, such as Figure 5A and Figure 5B The above-mentioned space may be formed by the first coupling part 120, the second coupling part 220, and the protrusion 230. For example, the space in which the adhesive member 800 is accommodated may be surrounded by the first coupling part 120, the second coupling part 220, and the protrusion 230.

[0098] The protrusion 230 may be configured to spatially connect the first window 110 of the first body 100 and the second window 210 of the second body 200 to each other. Therefore, light projected through the first window 110 may be incident on the image sensor 610 through the second window 210 without any interference. The protrusion 230 may be configured to block the inflow of the adhesive member 800. For example, the protrusion 230 is formed outside the first window 110 and the second window 210 to block the adhesive member 800 from extending through the first window 110 and the second window 210.

[0099] In the camera module 10 configured as described above, since the first body 100 and the second body 200 are formed to extend longitudinally in the optical axis C2 direction of the lens module 300, an optical imaging system having a long focal length can be implemented. In addition, in the camera module 10, since the connection between the first body 100 and the second body 200 is formed by the adhesive member 800 having a predetermined curing time, optical axis alignment between the first body 100 and the second body 200 is possible even in a combined state of the first body 100 and the second body 200. In addition, in the camera module 10, since a relatively large space for injecting or filling the adhesive member 800 is formed between the first body 100 and the second body 200, the combining reliability between the first body 100 and the second body 200 can be improved.

[0100] Next, we will refer to Figures 6 to 9 Camera modules according to other examples are described.

[0101] refer to Figure 6 and Figure 7 , the camera module 12 may include a housing 202. For example, the camera module 12 may include a housing 202 configured to be coupled to the filter member 700. However, the configuration of the camera module 12 is not limited to the housing 202. For example, the camera module 12 may further include an optical path changing unit and a lens module, such as Figure 8 and Fig. 9 shown.

[0102] The housing 202 may be configured such that the length in the first direction intersecting the optical axis C and the length in the second direction intersecting the optical axis C are different. For example, the length SBx of the housing 202 in the first direction may be greater than the length SBy of the housing 202 in the second direction. The housing 202 may be configured to accommodate the main components of the camera module 12. For example, the housing 202 may be configured to accommodate the image sensor 610. However, the components accommodated in the housing 202 are not limited to the image sensor 610. The housing 202 may be configured to allow light to be incident. For example, a window 210-3 may be formed on one surface of the housing 202 so that light refracted by the lens module can be projected onto the image sensor 610.

[0103] The window 210-3 may be formed to have a substantially rectangular shape. For example, the lengths of the first side 212 and the third side 216 of the window 210-3 may be less than the lengths of the adjacent second side 214 and the fourth side 218. The window 210-3 may be formed to be biased toward one side of the housing 202. For example, the window 210-3 may be formed to be biased toward one side of the housing 202 in the second direction. For example, the distances W1, W2, and W3 from the first side 212 to the third side 216 of the window 210-3 to the edges 202a, 202b, and 202c adjacent thereto may be greater than the distance W4 from the fourth side 218 to the fourth edge 202d of the housing 202 adjacent thereto.

[0104] The image sensor 610 may be disposed inside the housing 202. The image sensor 610 may be formed to be biased toward one side of the housing 202. For example, the image sensor 610 may be formed to be biased toward one side of the housing 202 in the second direction.

[0105] The housing 202 may be configured to stably fix the position of the filter member 700. For example, a step 240 on which the filter member 700 is to be mounted may be formed on one surface of the housing 202. The step 240 may be formed along an edge of the window 210-3.

[0106] The housing 202 may be configured to reduce the phenomenon of the adhesive member being introduced through the window 210-3. For example, the protrusion 230-3 may be formed on one surface of the housing 202 along the edge of the window 210-3. The protrusion 230-3 may be configured to surround different sides of the filter member 700. For example, the protrusion 230-3 may be formed to surround the second side 720, the third side 730, and the fourth side 740 of the filter member 700. The protrusion 230-3 may be configured to open one side of the filter member 700 or a portion of the filter member 700. For example, the protrusion 230-3 may be configured to expose a considerable portion of the first side 710 of the filter member 700 to the outside thereof.

[0107] The filter member 700 may be disposed in the housing 202. For example, the filter member 700 may be disposed on one surface of the housing 202 on which the window 210-3 is formed. The filter member 700 may be disposed to close the window 210-3. For example, the size of the filter member 700 may be set to completely cover the window 210-3 of the housing 202 so that foreign matter or adhesive members do not flow through the window 210-3.

[0108] The filter member 700 may be configured such that the length in the first direction intersecting the optical axis C is different from the length in the second direction intersecting the optical axis C. For example, the length FLx of the filter member 700 in the first direction may be greater than the length FLy of the filter member 700 in the second direction.

[0109] The filter member 700 may be stably positioned on one surface of the housing 202. For example, the filter member 700 may be disposed on the step 240 of the housing 202 to stably maintain the coupling position with the housing 202. The filter member 700 may be disposed to be biased toward one side of the housing 202. For example, the filter member 700 may be disposed to be biased toward one side of the housing 202 in the second direction. For example, the distance from the first side 710 of the filter member 700 to the fourth edge 202d of the housing 202 may be less than the distance from the third side 730 of the filter member 700 to the second edge 202b of the housing 202. The distance from the second side 720 of the filter member 700 to the first edge 202a of the housing 202 may be substantially equal to the distance from the fourth side 740 of the filter member 700 to the third edge 202c of the housing 202. As another example, the distance from the first side 710 of the filter member 700 to the fourth edge 202d of the housing 202 may be smaller than the distance from the second side 720 to the fourth side 740 of the filter member 700 to the edges 202a, 202b and 202c of the housing 202 adjacent thereto.

[0110] Similar to the protrusion 230-3, the filter member 700 may be configured to block the inflow of the adhesive member 800. For example, the first side 710 of the filter member 700 may be used as a structure for blocking the adhesive member 800 from flowing into the interior of the window 210-3. The filter member 700 may be formed to have a predetermined thickness Ft. For example, the thickness Ft of the filter member 700 may be greater than the depth Df of the step 240, which is the depth from one surface (e.g., the front surface) of the housing 202 to the bottom surface of the step 240. The deviation between the thickness Ft of the filter member 700 and the depth Df of the step 240 may be maintained at 50 μm or less. If the deviation between the thickness Ft of the filter member 700 and the depth Df of the step 240 exceeds 50 μm, the size reduction or thinning of the camera module 12 may be hindered due to the thickness of the filter member 700.

[0111] The adhesive member 800 may be applied to one surface of the housing 202. The adhesive member 800 may be configured to combine the housing 202 with other components of the camera module 12 or to reduce a flare phenomenon. For example, the adhesive member 800 may be configured to combine the housing 202 with the main body of the camera module 12. As another example, the adhesive member 800 may be applied to the first side 710 of the filter member 700 to block light from flowing in through the first side 710 of the filter member 700.

[0112] The camera module may have Figure 8 and Fig. 9 As an example, the camera module 12a may further include a first optical path changing unit 512a and a lens module 300, such as Figure 8As another example, the camera module 12b may include a first optical path changing unit 512a, a second optical path changing unit 512b, and a lens module 300, as shown in FIG. Fig. 9 shown.

[0113] In the following, reference will be made to Figures 10 to 17B A camera module according to another example is described.

[0114] refer to Figures 10 to 17B , the camera module 14 according to the example may include a first body 100-3 and a second body 200-3. However, the configuration of the camera module 14 is not limited to the first body 100-3 and the second body 200-3. For example, the camera module 14 may further include a shielding member 900 configured to cover the opening surface of the first body 100-3 and the side surface of the first body 100-3.

[0115] The first body 100-3 and the second body 200-3 are configured to be coupled together. For example, the first body 100-3 and the second body 200-3 may be coupled by a fastening member such as a protrusion and a groove. However, the coupling structure between the first body 100-3 and the second body 200-3 is not limited to fastening by a protrusion and a groove. For example, the first body 100-3 and the second body 200-3 may be securely coupled by an adhesive member.

[0116] The first body 100-3 may include a configuration for accommodating the second body 200-3. For example, a receiving portion 130 for accommodating the second body 200-3 may be formed on one side of the first body 100-3. The receiving portion 130 may be configured to limit the position of the second body 200-3 relative to the first body 100-3. For example, the receiving portion 130 may be configured to contact different sides 203, 204, and 206 of the second body 200-3. For example, the receiving portion 130 is formed to surround the three side surfaces 203, 204, and 206 of the second body 200-3 to contact the three side surfaces 203, 204, and 206, while not contacting the fourth side surface 208 of the second body 200-3. However, the inner surface 132 of the receiving portion 130 does not have to be configured to contact the three side surfaces 203, 204, and 206 of the second body 200-3. For example, the inner surface 132 of the receiving portion 130 may be formed to have a predetermined distance from the three side surfaces 203 , 204 , and 206 of the second body 200 - 3 .

[0117] Will refer to Fig.11 The first body 100 - 3 of the camera module 14 is described in detail.

[0118] The first body 100 - 3 may be configured to accommodate main components of the camera module 14. For example, the first body 100 - 3 may be configured to accommodate the lens module 300, the first optical path conversion module 510, and the second optical path conversion module 520.

[0119] The first body 100-3 may include a configuration for accommodating the lens module 300, the first optical path conversion module 510, and the second optical path conversion module 520. For example, the first body 100-3 may include a first housing 140. The first housing 140 may be formed of a material having a predetermined rigidity. For example, the first housing 140 may be formed of a metal material. However, the material of the first housing 140 is not limited to metal. For example, in order to reduce the weight of the camera module 14, the first housing 140 may also be formed of a plastic material.

[0120] The first optical path conversion module 510, the lens module 300, and the second optical path conversion module 520 may be sequentially disposed in the first housing 140. In detail, the first optical path conversion module 510 may be disposed on the object side of the lens module 300, and the second optical path conversion module 520 may be disposed on the image side of the lens module 300. The circuit board 150 may be disposed on the first housing 140. For example, the circuit board 150 may be configured to supply electrical signals and currents required to drive the first optical path conversion module 510 and the lens module 300, and may be disposed on the outer periphery of the first housing 140.

[0121] The first housing 140 may include a configuration capable of driving the lens module 300. For example, a guide groove 146 that enables the lens module 300 to move in one direction may be formed at the bottom of the first housing 140. Fig.10 Not shown, but related to Fig.12 A ball bearing similar to the illustrated ball bearing may be disposed in the guide groove 146 to reduce frictional resistance between the first housing 140 and the lens module 300 .

[0122] The first optical path conversion module 510 may be configured to convert the path of light incident in the camera module 14. For example, the first optical path conversion module 510 may be configured to reflect or refract the path of light incident along the first optical axis C1 in the direction of the second optical axis C2 intersecting the first optical axis C1.

[0123] The lens module 300 may be configured to form an image of light incident in the camera module 14 on an image sensor. For example, the lens module 300 may include one or more lenses. The lens module 300 may be configured to enable the camera module 14 to perform autofocus (AF) or focus magnification adjustment (zoom). For example, the lens module 300 may be movable in the direction of the second optical axis C2.

[0124] The second optical path conversion module 520 may be configured to convert the optical path of light emitted from the lens module 300. For example, the second optical path conversion module 520 may be configured to reflect or refract the path of light emitted along the second optical axis C2 in the direction of the third optical axis C3 intersecting the second optical axis C2.

[0125] The first body 100-3 may also include configurations other than the above configurations, or may be configured to have a coupling relationship with other configurations. For example, a substrate 600 on which an image sensor is mounted and a connection substrate 620 connected to the circuit board 150 may be additionally provided on one side of the first body 100-3.

[0126] Next, we will refer to Fig.12 The first optical path conversion module 510 is described.

[0127] The first optical path conversion module 510 may include a first optical path changing unit 512. The first optical path changing unit 512 may be configured to change the optical path. For example, the first optical path changing unit 512 may reflect or refract the path of light incident along the first optical axis C1 in the direction of the second optical axis C2. The first optical path changing unit 512 may be configured as a prism or a reflector. However, the shape of the first optical path changing unit 512 is not limited to a prism and a reflector. For example, the first optical path changing unit 512 may also be configured in different forms within a range in which light may be refracted or reflected.

[0128] The first optical path conversion module 510 may include a first movable member 514 and a second movable member 516. In addition, the first optical path conversion module 510 may further include a first driving unit 410.

[0129] The first movable member 514 may be coupled to the first optical path changing unit 512. For example, one surface of the first movable member 514 may include a receiving portion 5140 configured to accommodate the first optical path changing unit 512. The first movable member 514 may be coupled to the second movable member 516. For example, the second movable member 516 may be disposed on a rear surface of the first movable member 514. The ball bearing 5182 may be disposed between the first movable member 514 and the second movable member 516. For example, the ball bearing 5182 may be accommodated in a groove 5148 formed in the rear surface of the first movable member 514. The groove 5148 may be formed in a shape other than a hemisphere. For example, the groove 5148 may be formed in the form of a hexagonal pyramid, a quadrangular pyramid, a truncated hexagonal pyramid, or a truncated quadrangular pyramid shape engraved in the first movable member 514. Since the groove 5148 having the above-described shape has a relatively small area (point contact or line contact) that is substantially in contact with the ball bearing 5182, the rotational movement of the ball bearing 5182 can be smooth.

[0130] The first movable member 514 may be rotatable. For example, the first movable member 514 may be rotated based on two ball bearings 5182 respectively provided in the two grooves 5148. For example, the first movable member 514 may be rotated around an imaginary axis P1 connecting the centers of the ball bearings 5182.

[0131] The first movable member 514 may be coupled to the first driving unit 410. For example, receiving portions 5142 and 5144 for accommodating some components of the first driving unit 410 may be formed on both sides of the first movable member 514. The receiving portions 5142 and 5144 may be formed to have different sizes. For example, the second receiving portion 5144 may be formed to have a larger size than the first receiving portion 5142. However, the receiving portions 5142 and 5144 are not limited to Fig.12 The above-mentioned dimensional relationships or shapes shown.

[0132] A magnet 517 may be provided on the rear surface of the first movable member 514. The magnet 517 may be securely fitted into a fixing groove 5147 formed on the rear surface of the first movable member 514 so as not to be separated from the first movable member 514. The magnet 517 may be configured to prevent separation and position change of the first movable member 514. The magnet 517 applies an attractive force using a yoke (not shown) of the first housing 140 to reduce the position change of the first movable member 514 or the phenomenon that the first movable member 514 is separated from the first housing 140.

[0133] The second movable member 516 may be configured so that the first movable member 514 can rotate smoothly. For example, the second movable member 516 may be provided on the rear surface of the first movable member 514 to stably support the ball bearing 5182, which is the center of rotational movement of the first movable member 514.

[0134] The second movable member 516 may be configured to be rotatable. For example, the second movable member 516 may be rotated based on two ball bearings 5184 provided in the groove 5162. In more detail, the second movable member 516 may be rotated around an imaginary axis P2 connecting the centers of the ball bearings 5184.

[0135] The first driving unit 410 may be configured to provide a driving force required for the rotational movement of the first optical path changing unit 512. For example, the first driving unit 410 may provide a driving force required for the rotational movement of the first movable member 514 or a driving force required for the rotational movement of the second movable member 516.

[0136] The first driving unit 410 may include a first driving unit portion 412 and a second driving unit portion 414. The first driving unit portion 412 may provide a driving force required for the rotational movement of the first movable member 514, and the second driving unit portion 414 may provide a driving force required for the rotational movement of the second movable member 516. However, the configuration of the first driving unit 410 is not limited to including the first driving unit portion 412 and the second driving unit portion 414. For example, the first driving unit 410 may further include a magnet 416 for generating a magnetic force of a predetermined magnitude.

[0137] The first driving unit portion 412 may include a driving magnet 4122 and a driving coil 4124. However, the configuration of the first driving unit portion 412 is not limited to the driving magnet 4122 and the driving coil 4124. For example, the first driving unit portion 412 may also include a first detection sensor 4126. The driving magnet 4122 may be disposed on the first movable member 514, and the driving coil 4124 may be disposed on the first housing 140. In detail, the driving magnet 4122 is disposed in a receiving portion 5142 formed on a side surface of the first movable member 514, and the driving coil 4124 may be disposed on a surface of the circuit board 150 or the first housing 140 facing the driving magnet 4122.

[0138] The second driving unit portion 414 may include a driving magnet 4142 and a driving coil 4144. However, the configuration of the second driving unit portion 414 is not limited to the driving magnet 4142 and the driving coil 4144. For example, the second driving unit portion 414 may also include a second detection sensor 4146. The driving magnet 4142 may be provided on the first movable member 514, and the driving coil 4144 may be provided on the first housing 140. For example, the driving magnet 4142 may be provided in a receiving portion 5144 formed on a side surface of the first movable member 514, and the driving coil 4144 may be provided on one surface of the circuit board 150 or the first housing 140 facing the driving magnet 4142.

[0139] The first optical path conversion module 510 configured as described above may perform optical image stabilization of the camera module 14. For example, the first optical path conversion module 510 rotates the first movable member 514 by the driving force of the first driving unit part 412, or rotates the second movable member 516 by the driving force of the second driving unit part 414, thereby finely adjusting the path of light incident through the first optical path changing unit 512. In addition, the first optical path conversion module 510 detects the position of the first optical path changing unit 512 through the detection sensors 4126 and 4146 configured to detect the magnetic force of the magnet 416, and may adjust the position of the first optical path changing unit 512 based on the detected position information.

[0140] Next, we will refer to Fig.13 The lens module 300 is described.

[0141] The lens module 300 may include a lens 310, a lens barrel 320, and a barrel holder 330. However, the configuration of the lens module 300 is not limited thereto. For example, the lens module 300 may be configured to further include components other than the above configuration, or may be configured to be coupled to other components. For example, the lens module 300 may further include a second driving unit 420.

[0142] The lens module 300 may be configured to facilitate thinning of the camera module 14. For example, the lens 310 may be formed to have a length Lx in a first direction intersecting the second optical axis C2 and a length Ly in a second direction intersecting the second optical axis C2, and the length Lx and the length Ly are different from each other. As another example, the lens barrel 320 may be formed to have a length LMx in a first direction intersecting the second optical axis C2 and a length LMy in a second direction intersecting the second optical axis C2, and the length LMx and the length LMy are different from each other.

[0143] The lens module 300 may include one or more lenses 310. For example, the lens module 300 may include four or more lenses 310. However, the number of lenses constituting the lens module 300 is not limited to four.

[0144] The lens barrel 320 is configured to receive the lens 310. For example, the lens barrel 320 may be configured to accommodate all lenses included in the camera module 14.

[0145] The barrel holder 330 may be configured to be coupled to the lens barrel 320. For example, the barrel holder 330 may include a receiving portion 332 for accommodating a portion of the lens barrel 320 or a substantial portion of the lens barrel 320. The barrel holder 330 is configured to support the lens barrel 320. For example, the barrel holder 330 may support the lens barrel 320 so that the lens barrel 320 is stably positioned inside the first housing 140. The barrel holder 330 may be configured to be movable in the direction of the second optical axis C2. For example, the barrel holder 330 may be movable in the direction of the second optical axis C2 inside the first housing 140 via a ball bearing 340 assembled in the groove 334.

[0146] The second driving unit 420 may provide a driving force required for the linear movement of the barrel holder 330. For example, the second driving unit 420 may move the barrel holder 330 in the direction of the second optical axis C2 by using magnetic force. However, the driving force of the second driving unit 420 is not limited to magnetic force.

[0147] The second drive unit 420 may include a drive magnet 422 and a drive coil 424. However, the configuration of the second drive unit 420 is not limited to the drive magnet 422 and the drive coil 424. For example, the second drive unit 420 may further include a position detection sensor 426. The drive magnet 422 and the drive coil 424 may be provided on the lens barrel holder 330 and the first housing 140. For example, the drive magnet 422 may be provided on the mounting portion 336 of the lens barrel holder 330, and the drive coil 424 may be provided on one surface of the first housing 140 or one surface of the circuit board 150 that substantially faces the drive magnet 422.

[0148] The lens module 300 configured as described above can be moved in the second optical axis C2 direction by the driving force of the second driving unit 420, and can enable the camera module 14 to perform autofocus (AF) or focus magnification adjustment (zooming). In addition, since the length of the lens module 300 in the second direction intersecting the second optical axis C2 according to this example is smaller than the length in the first direction, the thickness of the camera module 14 can be reduced.

[0149] Next, we will refer to Fig.14 and Fig.15 The second body 200 - 3 is described.

[0150] The second body 200-3 may include a second shell 202. The second shell 202 is similar to the above reference Figures 6 to 9 The housing 202 described above corresponds to the housing 202. However, the configuration of the second body 200-3 is not limited to the second housing 202. For example, the second body 200-3 may further include an image sensor 610 and a filter member 700.

[0151] The second housing 202 may include a configuration for allowing light reflected or refracted by the second optical path conversion module 520 to be incident. For example, a window 210-3 may be formed in the second housing 202. The window 210-3 may be formed to have a shape similar to that of the image sensor 610. For example, the window 210-3 may be formed to have a rectangular shape. However, the shape of the window 210-3 is not limited to a rectangular shape.

[0152] The window 210-3 may be formed to be biased toward one side of the second housing 202. For example, a distance W1 from the first side 212 of the window 210-3 to the first edge 202a of the second housing 202 may be substantially equal to a distance W3 from the third side 216 of the window 210-3 to the third edge 202c of the second housing 202, but a distance W2 from the second side 214 of the window 210-3 to the second edge 202b of the second housing 202 may be different from a distance W4 from the fourth side 218 of the window 210-3 to the fourth edge 202d of the second housing 202. For example, a distance W4 from the fourth side 218 of the window 210-3 to the fourth edge 202d of the second housing 202 may be less than distances W1, W2, and W3 from the first side 212 to the third side 216 of the window 210-3 to the first edge 202a to the third edge 202c of the second housing 202.

[0153] A protrusion 230-3 may be formed on the second housing 202. In more detail, the protrusion 230-3 may be formed along the first side 212 to the third side 216 of the window 210-3. The protrusion 230-3 may be configured to block impurities or adhesive members from penetrating toward the window 210-3. For example, the protrusion 230-3 may be formed to have a predetermined height to reduce or prevent the phenomenon that impurities or adhesive members are introduced through the window 210-3.

[0154] A filter member 700 may be provided on the second housing 202. The filter member 700 may be configured to completely close the window 210-3. Therefore, the filter member 700 may block impurities or adhesive members from penetrating into the window 210-3. The filter member 700 may be configured to block light of a specific wavelength. For example, the filter member 700 may be configured to block infrared rays. However, the wavelength blocked by the filter member 700 is not limited to infrared rays. The filter member 700 may be provided on the inner side of the protrusion 230-3. For example, three sides 720, 730 and 740 of the filter member 700 may be closed by the protrusion 230-3. One side 710 of the filter member 700 may be configured to be exposed to the outside. For example, the first side 710 of the filter member 700 may be exposed to the outside without being closed by the protrusion 230-3. A predetermined space may be formed between the filter member 700 and the protrusion 230-3. For example, a space G for collecting foreign matter or bonding a member may be formed between the three sides 720, 730, and 740 of the filter member 700 and the protrusion 230-3. However, the space G is not always formed between the three sides 720, 730, and 740 of the filter member 700 and the protrusion 230-3. For example, the space G may be omitted if necessary.

[0155] The above components can be integrally combined through a predetermined process to configure Fig.16The camera module 14 in the form shown. The camera module 14 includes the first body 100-3 and the second body 200-3 as described above. The camera module 14 may also include a shielding member 900 to significantly reduce the influence of external impact or external magnetic field. The shielding member 900 may be configured to surround a substantial portion of the first body 100-3.

[0156] The camera module 14 may further include a configuration connected to an external signal and an external power source. For example, the camera module 14 may further include a substrate 600 and a connection substrate 620.

[0157] The camera module 14 may further include a configuration that enables a secure connection between the first body 100-3 and the second body 200-3. For example, the camera module 14 may further include a configuration such as Fig.17A and Fig. 17B The adhesive member 800 shown. The adhesive member 800 may be formed between the first body 100-3 and the second body 200-3. The protrusion 230-3 and the filter member 700 may prevent the adhesive member 800 from invading or flowing into the window 210-3. For example, the protrusion 230-3 and the filter member 700 may contact a portion of the first body 100 to completely close the gap through which the adhesive member 800 may invading or flowing. Therefore, according to this example, contamination of the lens or image sensor caused by the inflow of the adhesive member 800 may be reduced.

[0158] As described above, according to examples, the performance degradation of the camera module due to the inflow of the adhesive may be reduced.
