[0002] This application claims priority to Korean Patent Application No. 10-2021-0114943, filed on August 30, 2021, with the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

[0003] The following description relates to a camera, and more specifically, to a small camera used in a mobile device. Background Technology

[0004] Camera modules for use in mobile devices such as smartphones and tablets have been developed with reduced thickness. Furthermore, folding cameras using optical path alteration components such as prisms or mirrors have emerged to provide high magnification. To achieve low F-numbers and high resolution in folding cameras, the aperture of the lens may need to be at least a certain level or larger in size, and therefore, lenses with a portion of their aperture removed can be used (e.g., cut lenses).

[0005] A lens module, including a lens barrel and a lens housed within the lens barrel, may also include connecting members, such as a retaining ring for securing the lens. The retaining ring may be disposed on one side of the lens and may secure the lens to the lens barrel. Typically, the retaining ring may be disposed within the inner circumferential surface of the lens barrel or outside the outer circumferential surface. When the retaining ring is disposed within the lens barrel, the thickness of the lens barrel may increase due to the retaining ring; and when the retaining ring is disposed outside the lens barrel, the thickness of the entire lens assembly may increase due to the retaining ring. Reducing the thickness of the lens barrel is important in mobile devices, and it is necessary to eliminate or minimize the increase in lens barrel thickness caused by the retaining ring. Summary of the Invention

[0006] The summary portion of this invention is intended to provide a brief overview of the chosen inventive concepts, which will be further described in the detailed description portion below. This summary portion is not intended to identify key or essential features of the claimed subject matter, nor is it intended to help determine the scope of the claimed subject matter.

[0007] In one general aspect, the lens module includes: a lens barrel; a lens housed within the lens barrel; and a connecting member coupled to the lens barrel and disposed on one side of the lens to secure the lens to the lens barrel. The width of the lens in a first direction perpendicular to the optical axis is less than the width of the lens in a second direction perpendicular to the optical axis and intersecting the first direction. The lens barrel is configured to at least partially expose the connecting member in the first direction and at least partially overlap with the connecting member in the second direction.

[0008] The width of the connecting member in the first direction may be the same as or substantially the same as the width of the lens barrel in the first direction.

[0009] The lens barrel may include at least a first recess defined by a surface recessed from the object-side end surface of the lens barrel toward the image side, and the first recess is configured to partially accommodate a connecting member.

[0010] The lens barrel may include a first side portion defining the width of the lens barrel in a first direction and a second side portion defining the width of the lens barrel in a second direction. The first side portion may include a first recess configured to at least partially expose the connecting member in the first direction, and the second side portion may overlap with the connecting member in the second direction.

[0011] The connecting member may include a first portion defining the width of the connecting member in a first direction and a second portion defining the width of the connecting member in a second direction, the first portion being at least partially exposed in the first direction and the second portion being at least partially overlapping the lens barrel in the second direction.

[0012] When the connecting member and the lens barrel are connected to each other, the connecting member or the lens barrel may define a groove that connects to the connecting surface between the lens barrel and the connecting member.

[0013] The lens module may include an adhesive component disposed in the groove.

[0014] A lens may include linear portions that are opposite each other in a first direction and curved portions that are opposite each other in a second direction.

[0015] The connecting member may include a first part corresponding to the linear portion and a second part corresponding to the curved portion. Each of the first parts of the connecting member may contact the lens barrel in a direction parallel to the optical axis, and each of the second parts of the connecting member may contact the lens barrel in a direction perpendicular to the optical axis.

[0016] The lens barrel may include at least a first recess defined by a surface recessed from the object-side end surface of the lens barrel toward the image side, and each of the first recesses may accommodate at least a portion of one of the first portions of the connecting member.

[0017] Each of the second parts may be at least partially defined by a second recess defined by a surface recessed from the object-side end surface of the corresponding second part toward the image side.

[0018] In another general aspect, the lens module includes: a lens barrel; a lens housed within the lens barrel; and a connecting member connected to the lens barrel, disposed on one side of the lens, and configured to secure the lens to the lens barrel. The connecting member has a first portion that contacts the lens barrel in a direction parallel to the optical axis and a second portion that contacts the lens barrel in a direction perpendicular to the optical axis.

[0019] In another general aspect, the camera module includes: an optical path changing member configured to change the direction of light travel; a lens module disposed on one side of the optical path changing member and configured to move in the direction of the optical axis; and an image sensor.

[0030] 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

[0031] The following detailed embodiments are provided to help the reader gain a full understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents to the methods, apparatus, and / or systems described herein will be apparent to those skilled in the art. Except for operations that must occur in a specific order, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be obvious to those skilled in the art can be made. Furthermore, for clarity and brevity, descriptions of functions and structures known to those skilled in the art may be omitted.

[0032] The features described herein may be implemented in various forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to make this disclosure comprehensive and complete, and to fully convey the scope of this disclosure to those skilled in the art.

[0033] In this document, it should be noted that the use of the word "may" (e.g., what an example or embodiment may include or implement) with respect to examples or embodiments means that there exists at least one example or embodiment that includes or implements such a feature, but not all examples or embodiments are limited thereto.

[0034] 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.

[0035] As used herein, the term “and / or” includes any one of the associated listed items and any combination of any two or more items.

[0036] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, first assembly, first region, first layer, or first part mentioned in the examples may also be referred to as a second component, second assembly, second region, second layer, or second part.

[0037] Spatial relative terms such as “above,” “above,” “below,” and “below” 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 during 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 “below” that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses 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 spatial relative terms used herein should be interpreted accordingly.

[0038] 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 articles “a,” “an,” and “the” are intended to include plural forms as well. The terms “comprising,” “including,” and “having” indicate the presence of stated features, numbers, operations, components, elements, and / or combinations thereof, but do not preclude the presence or addition of one or more other features, numbers, operations, components, elements, and / or combinations thereof.

[0039] The shapes shown in the accompanying drawings may vary due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the accompanying drawings, but include shape variations that occur during manufacturing.

[0040] The features of the examples described herein can be combined in various ways, as will be apparent upon gaining an understanding of the disclosure of this application. Furthermore, although the examples described herein have multiple configurations, other configurations will be apparent upon gaining an understanding of the disclosure of this application.

[0041] The accompanying drawings may not be drawn to scale, and for clarity, illustration, and convenience, the relative dimensions, scale, and depiction of elements in the drawings may be exaggerated.

[0042] In the example, the X direction, Y direction, and Z direction can refer to the directions parallel to the X-axis, parallel to the Y-axis, and parallel to the Z-axis, respectively, as shown in the accompanying drawings. Furthermore, the X direction can include both the +X-axis and -X-axis directions, and unless otherwise stated, this also applies to the Y and Z directions.

[0043] In the examples, the concept of two directions (or axes) being parallel or perpendicular to each other can also include examples where two directions (or axes) are substantially parallel or substantially side by side. For example, the concept of a first axis and a second axis being perpendicular to each other can indicate that the first axis and the second axis can form an angle of 90 degrees or close to 90 degrees.

[0044] In the example, "configured as" means that the component includes the structure necessary to implement a certain function.

[0045] This disclosure is not limited to the specific examples, and it should be understood that various modifications may be made without departing from the spirit and scope of this disclosure.

[0046] Figure 1 This is a perspective view showing a camera module 1000 according to an example.

[0047] The camera module 1000 may include a housing 1100, a lens module 1200 disposed in the housing 1100, and an image sensor module 1300. The lens module 1200 may include at least one lens, and light passing through the at least one lens can reach the image sensor of the image sensor module 1300.

[0048] In this example, lens module 1200 may be disposed within housing 1100 and configured to move along the optical axis. In this example, camera module 1000 may include two or more lens modules. For example, camera module 1000 may also include an additional lens module 1200'. The focal length can be adjusted based on the movement of the two lens modules 1200 and 1200'. In this example, at least one of the two or more lens modules may be disposed within housing 1100 and configured to move along the optical axis. When the two or more lens modules are independently driven along the optical axis, the magnification can be adjusted.

[0049] In the example, camera module 1000 may include a light path alteration member 1400 configured to change the direction of light travel. For example, the light path alteration member 1400 may be implemented by a prism or a mirror. Light incident on camera module 1000 along the Y-axis can be folded by the light path alteration member 1400 and guided to lens module 1200. Through the light path alteration member 1400, camera module 1000 can have a reduced thickness and can provide a long overall track length, thereby providing an image with high magnification.

[0050] In the following text, reference will be made to Figures 2 to 9 Examples describing lens modules 1200 and 1200'. (See reference...) Figures 2 to 9 The described lens modules 100 and 200 can be applied to Figure 1 The camera module 1000.

[0051] In the following description, when describing a lens module or an element included in a lens module, the optical axis direction may refer to the direction of light travel. The optical axis direction may include an object-side direction and an image-side direction, and the object-side direction may refer to the direction from the lens module toward the object, while the image-side direction may refer to the direction from the lens module toward the image sensor. For example, the optical axis direction may be parallel to the Z-axis, the object-side direction may refer to the +Z direction, and the image-side direction may refer to the -Z direction.

[0052] Figure 2 This is a perspective view showing the lens module 100 according to the example. Figure 3 It is shown Figure 2 An exploded perspective view of the lens module 100 shown. Figure 4 It is along Figure 2 The sectional view taken by line I-I' in the middle. Figure 5 It is along Figure 2 The sectional view taken by line II-II' in the diagram. In the following description, reference will be made to... Figures 2 to 5 Describe an exemplary embodiment.

[0053] In the example, lens module 100 may include lens barrel 110, lens 120 disposed in lens barrel 110, and connecting member 130 configured to fix lens 120 to lens barrel 110. Lens module 100 may also include other elements besides those shown.

[0054] exist Figures 3 to 5 A single lens 120 may be disposed in the lens barrel 110, but its configuration is not limited to this. Lenses other than the lens 120 shown may be disposed in the lens barrel 110.

[0055] The connecting member 130 may be configured as a ring defining an entrance aperture corresponding to the optical axis O and extending along the edge of the lens 120. The connecting member 130 may at least partially contact the lens 120 and may be fixed and coupled to the lens barrel 110, thereby fixing the lens 120 to the lens barrel 110.

[0056] In the example, the lens barrel 110 may be configured to overlap a portion of the connecting member 130 in a direction perpendicular to the optical axis O, and may be configured to expose another portion of the connecting member 130 in the same direction. In this example, the configuration of exposing the connecting member 130 in a predetermined direction may mean that the lens barrel 110 may be configured not to cover the connecting member 130 in that predetermined direction, such that a portion of the connecting member 130 is visible when the lens module 100 is viewed along said predetermined direction.

[0057] In the example, the lens barrel 110 can be configured to at least partially expose the connecting member 130 in a first direction A1 perpendicular to the optical axis O. In the example, the lens barrel 110 can overlap with the connecting member 130 in a second direction A2 perpendicular to the optical axis O and intersecting the first direction A1. For example, refer to... Figure 4 and Figure 5 The connecting member 130 may partially overlap with the lens barrel 110 in the X direction and may be partially exposed in the Y direction.

[0058] In the example, lens module 100 can be configured such that the width of lens module 100 in a first direction A1 is smaller than its width in a second direction A2 intersecting the first direction A1. For example, the width of lens module 100 in the Y direction can be smaller than its width in the X direction. Therefore, the overall thickness of camera module 1000 can be reduced. In the following examples, the first direction A1 may correspond to the relatively small width of lens module 100 and may be referred to as the minor axis direction. The second direction A2 may correspond to the relatively large width of lens module 100 and may be referred to as the major axis direction. The minor axis direction A1 and the major axis direction A2 can be used to define the length of elements included in lens module 100 (e.g., lens barrel 110, lens 120, and connecting member 130).

[0059] Reference Figure 2 and Figure 4 In the example, the width W31 of the connecting member 130 in the minor axis direction A1 can be the same as or substantially the same as the width W11 of the lens barrel 110 in the minor axis direction A1. Therefore, the width of the lens module 100 in the minor axis direction A1 does not need to be increased due to the connecting member 130, and the thickness of the camera module 1000 can be reduced.

[0060] Reference Figure 3 In this example, the lens barrel 110 may include a first recess 111 configured to receive the connecting member 130. In this example, the lens barrel 110 may include a first recessed surface 113 recessed from the object-side end surface 112 toward the image side. The first recessed surface 113 and surfaces extending from both ends of the first recessed surface 113 to the object-side end surface 112 may define the first recess 111. A portion of the connecting member 130 may be disposed in the first recess 111 and may be exposed along its minor axis direction A1.

[0061] Reference Figure 3 In this example, the lens barrel 110 may include a first side portion 114 defining the width of the lens barrel 110 in the minor axis direction A1 and a second side portion 115 defining the width of the lens barrel 110 in the major axis direction A2. The first side portion 114 of the lens barrel 110 may be disposed on both sides in the minor axis direction A1 relative to the optical axis O, while the second side portion 115 of the connecting member 130 may be disposed on both sides in the major axis direction A2 relative to the optical axis O. The first side portion 114 may be disposed along the major axis direction A2 of the lens 120, and the second side portion 115 may be disposed along the minor axis direction A1 of the lens 120.

[0062] In this example, the lens barrel 110 may be configured to at least partially expose the connecting member 130 in the minor axis direction A1. For example, the first side 114 may include a first recess 111, and the connecting member 130 may be exposed through the first recess 111 in the minor axis direction A1. In this example, the lens barrel 110 may be configured to overlap with the connecting member 130 in the major axis direction A2. For example, the second side 115 of the lens barrel 110 may be configured to surround the outer peripheral surface of the connecting member 130.

[0063] Reference Figure 3 The connecting member 130 may include a first portion 131 defining the width of the connecting member 130 in the minor axis direction A1 and a second portion 132 defining the width of the connecting member 130 in the major axis direction A2. The first portion 131 of the connecting member 130 may be disposed on both sides in the minor axis direction A1 relative to the optical axis O, and the second portion 132 of the connecting member 130 may be disposed on both sides in the major axis direction A2 relative to the optical axis O.

[0064] Reference Figure 2 , Figure 4 and Figure 5The first portion 131 of the connecting member 130 may be at least partially exposed in the minor axis direction A1 through the first recess 111 of the lens barrel 110. The second portion 132 of the connecting member 130 may at least partially overlap with the lens barrel 110 in the major axis direction A2, and may not be exposed in the major axis direction A2.

[0065] Reference Figure 3 In this example, the width of lens 120 in a first direction A1 perpendicular to the optical axis O can be configured to be smaller than its width in a second direction A2 intersecting the optical axis O and the first direction A1. For example, the width of lens 120 in the Y direction can be smaller than the width of lens 120 in the X direction. Hereinafter, the first direction A1 may be referred to as the minor axis direction, and the second direction A2 may be referred to as the major axis direction.

[0066] In the example, lens 120 may have a cut-out shape. For example, the edge of lens 120 may include linear portions 121 opposite each other in the minor axis direction A1 and curved portions 122 opposite each other in the major axis direction A2. The width of lens 120 in the major axis direction A2 may correspond to the distance between the two curved portions 122, and the width of lens 120 in the minor axis direction A1 may correspond to the distance between the two linear portions 121.

[0067] In the example, lens 120 may include an optical unit 123 that exhibits optical properties and a flange unit 124 extending outwardly from the optical unit 123. The flange unit 124 may not exhibit optical properties and may be configured to secure lens 120 to lens barrel 110. For example, see reference... Figure 5 The lower surface of the connecting member 130 can contact the flange unit 124.

[0068] Reference Figure 3 In the example, the first portion 131 of the connecting member 130 may extend along the linear portion 121 of the lens 120, and the second portion 132 of the connecting member 130 may extend along the curved portion 122 of the lens 120. For example, the first portion 131 of the connecting member 130 may extend in the long axis direction A2, while the second portion 132 may extend in a circumferential direction relative to the optical axis O. Therefore, the overall shape of the connecting member 130 may be provided in a cut (or track) form similar to that of the lens 120.

[0069] In the example, the first side 114 of the lens barrel 110 may be provided in the form of a flat panel along the linear portion 121 of the lens 120, and the second side 115 may be provided in the form of a curved panel along the curved portion 122. Therefore, the overall shape of the lens barrel 110 may be provided in a cut (or track) form similar to that of the lens 120.

[0070] Reference Figure 4 The outer surface of the first portion 131 of the connecting member 130 may be the same as or substantially the same as the outer surface of the lens barrel 110. (Refer to...) Figure 5 The second portion 132 of the connecting member 130 can be disposed on the inner side of the lens barrel 110. That is, the outer surface of the second portion 132 can contact the inner surface of the lens barrel 110. For example, the width W32 of the second portion 132 of the connecting member 130 in the long axis direction A2 can be smaller than the width W12 of the second side portion 115 of the lens barrel 110 in the long axis direction A2.

[0071] Reference Figure 4 and Figure 5 In this example, a portion of the connecting member 130 may contact the lens barrel 110 in a direction parallel to or substantially parallel to the optical axis O. Another portion of the connecting member 130 may contact the lens barrel 110 in a direction perpendicular to or substantially perpendicular to the optical axis O. In this example, the configuration in which the connecting member 130 and the lens barrel 110 contact each other in a predetermined direction indicates that the connecting surfaces (or contact surfaces) between the elements may point in a predetermined direction. For example, the configuration in which the connecting member 130 and the lens barrel 110 contact each other in the Z direction indicates that the normal to the connecting surface between the connecting member 130 and the lens barrel 110 may be parallel to the Z direction.

[0072] In the example, the portion (or first portion 131) defining the width of the connecting member 130 in the minor axis direction A1 can contact the lens barrel 110 in a direction parallel to or substantially parallel to the optical axis O. For example, refer to Figure 4 The first connecting surface 133 between the lens barrel 110 and the connecting member 130 may be perpendicular to the Z-axis. In the example shown, the first connecting surface 133 between the lens barrel 110 and the connecting member 130 may extend along the minor axis direction A1 (Y direction), but its configuration is not limited to this. In another example, the first connecting surface 133 may include an inclined surface. For example, the first connecting surface 133 may extend in a direction between the Z and Y directions.

[0073] In the example, the portion (or second portion 132) defining the width of the connecting member 130 in the long axis direction A2 can contact the lens barrel 110 in a direction perpendicular to or substantially perpendicular to the optical axis O. (Refer to...) Figure 5 The second connecting surface 134 between the lens barrel 110 and the connecting member 130 can be perpendicular to the X-axis. In the example shown, the second connecting surface 134 between the lens barrel 110 and the connecting member 130 can extend in the optical axis O direction (Z direction), but its configuration is not limited to this. In another example, the second connecting surface 134 can include an inclined surface. For example, the second connecting surface 134 can extend in a direction between the X and Z directions.

[0074] In the example, the connecting member 130 or the lens barrel 110 may be configured to define a groove 135 between the lens barrel 110 and the connecting member 130 when the connecting member 130 and the lens barrel 110 are connected to each other. (See reference...) Figure 5 A groove 135 may be formed between the connecting member 130 and the lens barrel 110. In this example, an adhesive member 140 may be disposed in the groove 135. The adhesive member 140 may be configured to secure the connecting member 130 to the lens barrel 110. The adhesive member 140 may liquid fill the groove 135, may cure, and may secure the connecting member 130 to the lens barrel 110.

[0075] Reference Figure 5 In the example, the groove 135 can be connected to the second coupling surface 134 between the coupling member 130 and the lens barrel 110. A portion of the adhesive member 140 filling the groove 135 can penetrate into the second coupling surface 134 and can further strengthen the connection between the coupling member 130 and the lens barrel 110.

[0076] In the example, the groove 135 may be formed between the portion (second portion 132) defining the length of the connecting member 130 in the long axis direction A2 and the lens barrel 110. (See reference...) Figure 5 The second part 132 may include a second recessed surface 136 recessed from the object-side end surface 130a of the connecting member 130 toward the image-side. The second recessed surface 136 may partially form the bottom surface of the groove 135.

[0077] The second portion 132 of the connecting member 130 and the lens barrel 110 may each include inclined surfaces 137 and 116 that partially define the groove 135. For example, see reference... Figure 5The second portion 132 of the connecting member 130 may include an inclined surface 137 extending from the second recessed surface 136 toward the object side. The second side portion 115 of the lens barrel 110 may include an inclined surface 116 that is connected to the connecting member 130 to the second connecting surface 134 and extends toward the object side.

[0078] In the example, the connecting member 130 may include a second recess 139 defined at least partially by a third recessed surface 138 recessed from the object-side end surface 130a toward the image-side. The second recess 139 may connect to a groove 135 and may provide space in which a needle-shaped adhesive filling device may be disposed for injecting the adhesive member 140 into the groove 135. In the example, the second recess 139 may be formed in a portion (second portion 132) defining the length of the connecting member 130 in the long axis direction A2. See also... Figure 5 The second concave surface 136 can be recessed downward from the third concave surface 138.

[0079] Figure 6 This is a perspective view showing the lens module 200 according to the example. Figure 7 It is shown Figure 6 An exploded perspective view of the lens module 200 shown. Figure 8 It is along Figure 6 The sectional view taken from line III-III' in the middle. Figure 9 It is along Figure 6 The sectional view taken by line IV-IV' in the diagram. (Refer to...) Figure 6 to Figure 9 Describe an exemplary embodiment.

[0080] In the example, lens module 200 may include lens barrel 210, lens 220 disposed in lens barrel 210, and connecting member 230 configured to fix lens 220 to lens barrel 210. Lens module 200 may also include elements other than those shown.

[0081] exist Figures 7 to 9 A single lens 220 may be disposed in the lens barrel 210, but its configuration is not limited to this. Lenses other than the lens 220 shown may be disposed in the lens barrel 210.

[0082] The connecting member 230 may be provided in the form of a ring that defines an entrance aperture corresponding to the optical axis O and extends along the edge of the lens 220. The connecting member 230 may at least partially contact the lens 220 and may be fixed and coupled to the lens barrel 210, thereby fixing the lens 220 to the lens barrel 210.

[0083] In the example, the lens barrel 210 can be configured to overlap a portion of the connecting member 230 in a direction perpendicular to the optical axis O, and can be configured to expose another portion of the connecting member 230 in the same direction. In this example, the configuration of exposing the connecting member 230 in a predetermined direction can mean that the lens barrel 210 can be configured not to cover the connecting member 230 in that predetermined direction, such that a portion of the connecting member 230 is visible when the lens module 200 is viewed along that predetermined direction.

[0084] In the example, the lens barrel 210 can be configured to at least partially expose the connecting member 230 in a first direction A1 perpendicular to the optical axis O. In the example, the lens barrel 210 can overlap with the connecting member 230 in a second direction A2 perpendicular to the optical axis O and intersecting the first direction A1. For example, refer to... Figure 8 and Figure 9 The connecting member 230 may partially overlap with the lens barrel 210 in the X direction and may be partially exposed in the Y direction.

[0085] In the example, lens module 200 can be configured such that its width in a first direction A1 is smaller than its width in a second direction A2 intersecting the first direction A1. For example, the width of lens module 200 in the Y direction can be smaller than its width in the X direction. Therefore, the overall thickness of lens module 200 can be reduced. In the following examples, the first direction A1 may correspond to the relatively small width of lens module 200 and may be referred to as the minor axis direction. The second direction A2 may correspond to the relatively large width of lens module 200 and may be referred to as the major axis direction. The minor axis direction A1 and the major axis direction A2 can be used to define the lengths of elements included in lens module 200 (e.g., lens barrel 210, lens 220, and connecting member 230).

[0086] Reference Figure 6 and Figure 8 In the example, the width W31' of the connecting member 230 in the minor axis direction A1 can be the same as or substantially the same as the width W11' of the lens barrel 210 in the minor axis direction A1. Therefore, the width of the lens module 200 in the minor axis direction A1 does not need to be increased due to the connecting member 230, and the thickness of the camera module on which the lens module 200 is mounted can be reduced.

[0087] Reference Figure 7In the example, the lens barrel 210 may include a first side portion 214 defining the width of the lens barrel 210 in the minor axis direction A1 and a second side portion 215 defining the width of the lens barrel 210 in the major axis direction A2. The first side portion 214 of the lens barrel 210 may be disposed on both sides relative to the optical axis O in the minor axis direction A1, while the second side portion 215 of the connecting member 230 may be disposed on both sides relative to the optical axis O in the major axis direction A2. The first side portion 214 may be disposed along the major axis direction A2 of the lens 220, and the second side portion 215 may be disposed along the minor axis direction A1 of the lens 220.

[0088] In this example, the lens barrel 210 may be configured to at least partially expose the connecting member 230 in the minor axis direction A1. In this example, the lens barrel 210 may be configured to overlap with the connecting member 230 in the major axis direction A2. For example, the connecting member 230 may be configured to partially surround a second side 215 of the lens barrel 210.

[0089] Reference Figure 7 In the example, the connecting member 230 may include a first portion 231 defining the width of the connecting member 230 in the minor axis direction A1, and a second portion 232 defining the width of the connecting member 230 in the major axis direction A2. The first portion 231 of the connecting member 230 may be disposed on both sides in the minor axis direction A1 relative to the optical axis O, and the second portion 232 of the connecting member 230 may be disposed on both sides in the major axis direction A2 relative to the optical axis O.

[0090] Reference Figure 6 , Figure 8 and Figure 9 The first portion 231 of the connecting member 230 may be exposed in the minor axis direction A1 of the lens barrel 210. The second portion 232 of the connecting member 230 may at least partially overlap with the lens barrel 210 in the major axis direction A2, and a portion of the lens barrel 210 may not be exposed in the major axis direction A2.

[0091] Reference Figure 7 In this example, the width of lens 220 in a first direction A1 perpendicular to the optical axis O can be configured to be smaller than its width in a second direction A2 intersecting the optical axis O and the first direction A1. For example, the width of lens 220 in the Y direction can be smaller than its width in the X direction. Hereinafter, the first direction A1 may be referred to as the minor axis direction, and the second direction A2 may be referred to as the major axis direction.

[0092] In the example, lens 220 may have a cut-out shape. For example, the edge of lens 220 may include linear portions 221 opposite each other in the minor axis direction A1 and curved portions 222 opposite each other in the major axis direction A2. The width of lens 220 in the major axis direction A2 may correspond to the distance between the two curved portions 222, and the width of lens 220 in the minor axis direction A1 may correspond to the distance between the two linear portions 221.

[0093] In the example, lens 220 may include an optical unit 223 that exhibits optical properties and a flange unit 224 extending outward from the optical unit 223. The flange unit 224 may not exhibit optical properties and may be configured to secure lens 220 to lens barrel 210. For example, see reference... Figure 9 The lower surface of the connecting member 230 can contact the flange unit 224.

[0094] Reference Figure 7 In the example, the first portion 231 of the connecting member 230 may extend along the linear portion 221 of the lens 220, and the second portion 232 of the connecting member 230 may extend along the curved portion 222 of the lens 220. For example, the first portion 231 of the connecting member 230 may extend along the major axis direction A2, and the second portion 232 may extend along a circumferential direction relative to the optical axis O. Therefore, the overall shape of the connecting member 230 may be provided in a cut (or track) form similar to that of the lens 220.

[0095] In the example, the first side 214 of the lens barrel 210 may be provided in the form of a flat panel along the linear portion 221 of the lens 220, and the second side 215 may be provided in the form of a curved panel along the curved portion 222. Therefore, the overall shape of the lens barrel 210 may be provided in a cut (or track) form similar to that of the lens 220.

[0096] Reference Figure 8 The outer surface of the first portion 231 of the connecting member 230 may be the same as or substantially the same as the outer surface of the lens barrel 210. (Refer to...) Figure 9The second portion 232 of the connecting member 230 may include a first extension 232a extending toward the image side, and the first extension 232a may surround the outer circumferential surface of the lens barrel 210 in the circumferential direction. Furthermore, the second side portion 215 of the lens barrel 210 may include a second extension 215a extending toward the object side, and the second extension 215a may contact the inner surface of the connecting member 230. For example, the width W12' of the second portion 232 of the connecting member 230 in the major axis direction A2 may be greater than the width W32' of the second extension 215a of the second side portion 215 of the lens barrel 210 in the major axis direction A2.

[0097] Reference Figure 8 and Figure 9 In this example, a portion of the connecting member 230 may contact the lens barrel 210 in a direction parallel to or substantially parallel to the optical axis O. Another portion of the connecting member 230 may contact the lens barrel 210 in a direction perpendicular to or substantially perpendicular to the optical axis O. In this example, the configuration of the connecting member 230 and the lens barrel 210 contacting each other in a predetermined direction indicates that the connecting surfaces (or contact surfaces) between the elements may point in a predetermined direction. For example, the configuration of the connecting member 230 and the lens barrel 210 contacting each other in the Z direction indicates that the normal to the connecting surface between the connecting member 230 and the lens barrel 210 may be parallel to the Z direction.

[0098] In the example, the portion (or first portion 231) defining the width of the connecting member 230 in the minor axis direction A1 can contact the lens barrel 210 in a direction parallel to or substantially parallel to the optical axis O. For example, refer to Figure 8 The first connecting surface 233 between the lens barrel 210 and the connecting member 230 can be perpendicular to the Z-axis. In the example shown, the first connecting surface 233 between the lens barrel 210 and the connecting member 230 can extend along the minor axis direction A1 (Y direction), but its configuration is not limited to this. In another example, the first connecting surface 233 can include an inclined surface. For example, the first connecting surface 233 can extend in a direction between the Z and Y directions.

[0099] In the example, the portion (or second portion 232) defining the width of the connecting member 230 in the long axis direction A2 can contact the lens barrel 210 in a direction perpendicular to or substantially perpendicular to the optical axis O. (See reference...) Figure 9The second connecting surface 234 between the lens barrel 210 and the connecting member 230 can be perpendicular to the X-axis. In the example shown, the second connecting surface 234 between the lens barrel 210 and the connecting member 230 can extend in the optical axis O direction (Z direction), but its configuration is not limited to this. In another example, the second connecting surface 234 can include an inclined surface. For example, the second connecting surface 234 can extend in a direction between the X and Z directions.

[0100] In the example, the connecting member 230 or the lens barrel 210 may be configured to define a groove 235 between the lens barrel 210 and the connecting member 230 when the connecting member 230 and the lens barrel 210 are connected to each other. (See also...) Figure 9 A groove 235 may be formed between the connecting member 230 and the lens barrel 210. In this example, an adhesive member may be disposed in the groove 235. The adhesive member may be configured to secure the connecting member 230 to the lens barrel 210. The adhesive member may liquid fill the groove 235, may cure, and may secure the connecting member 230 to the lens barrel 210.

[0101] Reference Figure 9 In this example, the groove 235 can be connected to a second connecting surface 234 between the connecting member 230 and the lens barrel 210. A portion of the adhesive member filling the groove 235 can penetrate into the second connecting surface 234 and further strengthen the connection between the connecting member 230 and the lens barrel 210.

[0102] In the example, the groove 235 may be formed between the portion (second portion 232) that defines the length of the connecting member 230 in the long axis direction A2 and the lens barrel 210.

[0103] Based on the above example, a camera module with reduced thickness and high performance can be provided.
