[0002] This application claims the benefit of priority to Korean Patent Application No. 10 - 2020 - 0169869, filed on December 7, 2020, 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 module having an optical image stabilization function. Background art

[0004] The camera module is configured to enable clear imaging. For example, the camera module includes an image stabilization unit that can correct the shaking of the lens module caused by an external impact. The image stabilization unit is configured to move the lens module in a direction intersecting the optical axis. For example, the image stabilization unit can significantly reduce the shaking of the lens module by applying a driving force on one side or the other side of the lens module.

[0005] A camera module having an image stabilization function is configured such that the lens module can move. For example, the lens module of the above - mentioned camera module can move in a direction intersecting the optical axis. However, excessive movement of the lens module may cause a collision between the lens module and the housing that houses the lens module, and thus the camera module may fail. For example, when the camera module is shaken excessively by a user or an impact is applied to the camera module, the lens module may be damaged, or the camera module may be damaged.

For clarity, illustration, and convenience, the drawings may not be drawn to scale, and the relative dimensions, proportions, and depictions of elements in the drawings may be exaggerated. Detailed Description

[0034] The following specific embodiments are provided to assist the reader in obtaining a comprehensive understanding of the methods, apparatuses, and / or systems described in this application. However, various changes, modifications, and equivalents of the methods, apparatuses, and / or systems described in this application will be apparent after understanding the disclosure of this application. For example, the order of operations described in this application is merely exemplary and, except for operations that must occur in a specific order, is not limited to the order set forth in this application and may be changed, which will be apparent after understanding the disclosure of this application. Additionally, descriptions of well-known features in the art may be omitted for greater clarity and conciseness.

[0035] The features described in this application may be implemented in different forms and should not be construed as limited to the examples described in this application. Rather, the examples described in this application are provided only to illustrate some of the many possible ways of implementing the methods, apparatuses, and / or systems described in this application that will be apparent after understanding the disclosure of this application.

[0036] It should be noted that in this application, the use of the phrase "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 in which such a feature is included or implemented, and not all embodiments and examples are so limited.

[0037] 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," directly "connected to," or directly "coupled to" the other element, or there may be one or more other elements intervening between the element and the other element. In contrast, when an element is described as being "directly on," "directly connected to," or "directly coupled to" another element, there are no other elements intervening between the element and the other element.

[0038] As used in this application, the phrase "and / or" includes any one of the associated listed items and any combination of any two or more of them.

[0039] Although terms such as "first", "second", and "third" may be used in this application to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited by these terms. Rather, these terms are only used to distinguish one component, part, region, layer, or section from another. Thus, without departing from the teachings of the examples described in this application, the first component, first part, first region, first layer, or first section mentioned in these examples may also be referred to as the second component, second part, second region, second layer, or second section.

[0040] Spatial relative terms such as "above", "upper", "below", and "lower" may be used in this application for convenience of description to describe the relationship of one element relative to another as shown in the figures. In addition to covering the orientations depicted in the figures, 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 figures is flipped, an element described as "above" or "upper" relative to another element will be "below" or "lower" relative to that other element. Thus, depending on the spatial orientation of the device, the term "above" covers both the orientations of "above" and "below". The device may also be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used in this application should be interpreted accordingly.

[0041] The terms used in this application are only for describing various examples and are not intended to limit the disclosure. Unless the context clearly indicates otherwise, the articles "a", "an", and "the" are intended to also include the plural forms. The terms "comprising", "including", and "having" specify the presence of the 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.

[0042] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the figures may occur. Thus, the examples described in this application are not limited to the specific shapes shown in the figures, but include shape variations that occur during manufacturing.

[0043] The features of the examples described in this application may be combined in various ways that will be apparent after obtaining an understanding of the disclosure of this application. In addition, although the examples described in this application have various configurations, other configurations that will be apparent after obtaining an understanding of the disclosure of this application are also possible.

[0044] One aspect of the present disclosure is to provide a camera module configured to significantly reduce movement of a lens module caused by an external impact while providing an optical image stabilization function.

[0045] The camera module described herein can be mounted on a portable electronic product. For example, the camera module can be mounted on a portable phone, a laptop computer, etc. In addition, the scope of use of the camera module is not limited to the above-described electronic devices. For example, the camera module can be mounted on all electronic devices that require screen imaging and video recording, such as motion detection, image capture, face recognition, iris recognition, virtual reality implementation, and augmented reality implementation.

[0046] The camera module includes an optical image stabilization (OIS) function to reduce a decrease in resolution caused by hand shake. For example, the camera module is configured to drive the lens module in a direction intersecting the optical axis. In the case where the camera module includes the OIS function, the lens module can be driven in a direction intersecting the optical axis, and thus, the lens module may be damaged due to collision with the housing due to an external impact, or noise may be generated due to rapid movement of the lens module.

[0047] The camera module described herein can be configured to prevent the above problems. For example, the camera module can perform optical image stabilization (OIS) through a locus movement of the lens module. Specifically, the camera module can perform OIS by rotating the lens module around a plurality of axes. Therefore, in the camera module, since the lens module does not move in a direction facing the housing, noise and damage caused by collision between the lens module and the housing can be reduced.

[0048] According to an example, the camera module includes a lens module, a movable member and a fixed member that enable the lens module to move in a direction intersecting the optical axis, and a driving unit that provides a driving force required to drive the movable member.

[0049] A plurality of movable members can be configured. For example, the movable member can include a first movable member and a second movable member. The first movable member is configured to rotate around a virtual first axis intersecting the optical axis of the lens module, and the second movable member is configured to rotate around a virtual second axis intersecting the optical axis of the lens module.

[0050] The fixed member is configured to support one or more movable members. For example, the fixed member can support the second movable member so that the rotation of the second movable member is smoothly performed.

[0051] The driving unit may include a plurality of driving units. For example, the driving unit may include a first driving unit that provides a driving force required to rotate the first movable member and a second driving unit that provides a driving force required to rotate the second movable member. In addition, the driving unit may include one or more driving magnets. For example, the first driving unit may include a first driving magnet disposed on the first movable member. The second driving unit may include a second driving magnet disposed on the second movable member.

[0052] The first driving unit and the second driving unit may be arranged to generate driving forces in directions intersecting each other. For example, the first driving unit may be arranged to generate a driving force in a direction on the first side of the lens module, and the second driving unit may be arranged to generate a driving force in a direction on the second side of the lens module. However, the arrangement of the first driving unit and the second driving unit is not limited to the above configuration. For example, the arrangement of the first driving unit and the second driving unit may be changed within a range where image stabilization can be achieved by the driving forces of the first driving unit and the second driving unit.

[0053] The driving unit may further include driving coils. For example, the first driving unit may further include a first driving coil, and the second driving unit may further include a second driving coil. The driving coils may be arranged to face the driving magnets. For example, the first driving coil may be arranged to face the first driving magnet, and the second driving coil may be arranged to face the second driving magnet. The driving coils may be disposed on a member that houses the movable member and the fixed member. For example, the driving coils may be directly or indirectly disposed in a housing configured to house the movable member and the fixed member.

[0054] The virtual first axis and the virtual second axis may be formed in different directions. For example, the virtual first axis may be formed in the first short axis direction or the first width direction of the fixed member. The virtual second axis may be formed in the second short axis direction or the second width direction of the fixed member. As another example, the virtual first axis may be formed in the first long axis direction or the first diagonal direction of the fixed member, and the virtual second axis may be formed in the second long axis direction or the second diagonal direction of the fixed member.

[0055] The first movable member, the second movable member, and the fixed member may be sequentially arranged in the optical axis direction. For example, the first movable member, the second movable member, and the fixed member may be sequentially arranged from the object side toward the imaging surface (or image sensor). Specifically, the second movable member may be disposed below the first movable member, and the fixed member may be disposed below the second movable member. However, the arrangement order of the first movable member, the second movable member, and the fixed member is not limited to the above form. For example, the second movable member, the first movable member, and the fixed member may also be arranged in sequence.

[0056] The camera module may further include a support member. For example, the camera module may include a first support member disposed between the first movable member and the second movable member and a second support member disposed between the second movable member and the fixed member.

[0057] The support member may be configured such that the first movable member and the second movable member can perform a rotational movement. For example, the first support member may enable the first movable member to perform a relative rotational movement with respect to the second movable member. The second support member may enable the second movable member to perform a relative rotational movement with respect to the fixed member. The support member may be assembled into a groove of the movable member. For example, the first support member may be assembled into a first groove of the first movable member, and the second support member may be assembled into a second groove of the second movable member. The support member may be in substantially rolling contact with the movable member. For example, one end of the support member may be formed with a curved surface so that the movable member can perform a rotational movement. The support member may extend in the optical axis direction.

[0058] The support member may be formed to facilitate bending deformation. For example, grooves for enabling the support member to bend and deform may be respectively formed in some regions of the first support member and the second support member.

[0059] According to another example, the camera module includes a lens module, a fixed member, a movable member, and a driving unit, where the fixed member and the movable member enable the lens module to move in a direction intersecting the optical axis, and the driving unit provides a driving force required to drive the movable member.

[0060] The lens module includes one or more lenses disposed along the optical axis. For example, the lens module may include four or more lenses. However, the number of lenses constituting the lens module is not limited to four. For example, the lens module may include three or fewer lenses or five or more lenses, and these lenses are sequentially arranged in ascending numerical order along the optical axis from the object side of the optical imaging system toward the imaging surface of the camera module, where the first lens is closest to the object side of the camera module and the last lens is closest to the imaging surface. The lenses may be spaced apart from each other by a predetermined distance along the optical axis. The lens module may be configured to rotate about a virtual first axis intersecting the optical axis.

[0061] The movable member is configured to support the lens module. For example, the movable member may support the lens module to achieve the trajectory or rotational movement of the lens module. In addition, the movable member may be configured to rotate in a direction different from the direction of the lens module. For example, the movable member may be configured to rotate about a virtual second axis intersecting the optical axis.

[0062] The fixed member is configured to support the movable member. For example, the fixed member may support the movable member such that the trajectory or rotational movement of the movable member can be smoothly performed.

[0063] The driving unit may include a plurality of driving units. For example, the driving unit may include a first driving unit that provides a driving force required to rotate the lens module and a second driving unit that provides a driving force required to rotate the movable member. In addition, the driving unit may include one or more driving magnets. For example, the first driving unit may include a first driving magnet provided on the lens module, and the second driving unit may include a second driving magnet provided on the movable member.

[0064] The first driving unit and the second driving unit may be arranged to generate driving forces in directions intersecting each other. The first driving unit may generate a driving force such that the lens module rotates about a virtual first axis, and the second driving unit may generate a driving force such that the movable member rotates about a virtual second axis.

[0065] The first driving magnet and the second driving magnet may be formed on a plurality of different side surfaces of the lens module and the movable member. For example, the first driving magnet may be formed on the first side and the second side of the lens module respectively, and the second driving magnet may be formed on the first side and the second side of the movable member respectively. One of the first driving magnets provided on the first side and the second side of the lens module may generate a driving force in the same direction as one of the second driving magnets provided on the first side and the second side of the lens module. For example, the first side of the lens module may be a portion in the same direction as the first side of the movable member, but the second side of the lens module and the second side of the movable member may be portions in different directions.

[0066] The driving unit may further include driving coils. For example, the first driving unit may further include a first driving coil, and the second driving unit may further include a second driving coil. The driving coils may be arranged to face the driving magnets. For example, the first driving coil may be arranged to face the first driving magnet, and the second driving coil may be arranged to face the second driving magnet. The driving coils may be provided on a member that receives the movable member and the fixed member. For example, the driving coils may be directly or indirectly provided in a housing configured to receive the movable member and the fixed member.

[0067] The virtual first axis and the virtual second axis may be formed in different directions. For example, the virtual first axis may be formed in the first minor axis direction or the first width direction of the fixed member, and the virtual second axis may be formed in the second minor axis direction or the second width direction of the fixed member. As another example, the virtual first axis may be formed in the first major axis direction or the first diagonal direction of the fixed member, and the virtual second axis may be formed in the second major axis direction or the second diagonal direction of the fixed member.

[0068] The camera module may further include a support member. For example, the camera module may include a first support member disposed between the first movable member and the second movable member, and a second support member disposed between the second movable member and the fixed member.

[0069] The support member may be configured such that the first movable member and the second movable member can perform rotational movement. For example, the first support member may enable the first movable member to perform relative rotational movement with respect to the second movable member. The second support member may enable the second movable member to perform relative rotational movement with respect to the fixed member. The support member may be assembled into a groove of the movable member. For example, the first support member may be assembled into a first groove of the first movable member, and the second support member may be assembled into a second groove of the second movable member. The support member may be in substantially rolling contact with the movable member. For example, one end of the support member may be formed with a curved surface so that the movable member can perform rotational movement. The support member may extend in the optical axis direction.

[0070] Hereinafter, examples will be described in detail based on the drawings.

[0071] First, reference will be made to Figures 1 to 6 Describe a camera module according to an example.

[0072] As Figure 1 shown, the camera module 10 according to the example may include a lens module 100, a first movable member 200, a second movable member 300, a first support member 380, a fixed member 400, a second support member 480, a first driving unit 500, and a second driving unit 600. However, the configuration of the camera module 10 is not limited to these components. For example, the camera module 10 may further include a first substrate 710, a second substrate 720, an image sensor 730, a housing 800, a shielding cover 900, etc.

[0073] The lens module 100 may include a lens 110, a lens barrel 120, and a barrel bracket 130. However, the configuration of the lens module 100 is not limited to the above components. For example, the lens barrel 120 and the barrel bracket 130 may be integrally formed, or the barrel bracket 130 may be omitted from the configuration of the lens module 100. The lens module 100 may include one or more lenses 110. For example, the lens module 100 may include five or more lenses 110. However, the configuration of the lens module 100 is not limited to five lenses 110. For example, the lens module 100 may include four or fewer lenses 110 or six or more lenses 110. The lens barrel 120 may be configured to align a plurality of lenses 110 in the direction of the optical axis C. For example, the lens barrel 120 may align the optical axis C of the lenses 110 by contact coupling with the lenses 110. The barrel bracket 130 is configured to receive the lens barrel 120. The barrel bracket 130 may be formed to facilitate the coupling between the lens module 100 and other components. For example, the barrel bracket 130 may be formed in the shape of a small planar body that facilitates contact coupling with other components.

[0074] The first movable member 200 is configured to be coupled to the lens module 100. For example, the first movable member 200 may be coupled to the barrel bracket 130 of the lens module 100. The first movable member 200 may be configured to enable rotational driving. For example, the first movable member 200 may be configured to rotate about a virtual first axis P1 that intersects the optical axis C in a state where the first movable member 200 is coupled to the lens module 100. The first movable member 200 may be formed to be coupled to some components of the first driving unit 500. For example, on one side of the first movable member 200, a first receiving portion 210 may be formed, and the first driving magnet 510 of the first driving unit 500 may be disposed in the first receiving portion 210. The first receiving portion 210 may be configured to accommodate the first driving magnet 510. For example, the internal space of the first receiving portion 210 may be formed to have substantially the same dimensions and shape as the dimensions and shape of the first driving magnet 510.

[0075] The second movable member 300 may be disposed between the first movable member 200 and the fixed member 400. For example, the second movable member 300 may be located above the fixed member 400 and below the first movable member 200. The second movable member 300 may support the first movable member 200 so that the first movable member 200 can rotate. For example, the second movable member 300 may support the first movable member 200 through the first support member 380 so that the first movable member 200 can rotate. The second movable member 300 may be coupled to the first support member 380. For example, a coupling groove into which the first support member 380 will be inserted may be formed in one surface of the second movable member 300.

[0076] The second movable member 300 can be configured to enable rotational driving. For example, the second movable member 300 can be configured to rotate about a virtual second axis P2 that intersects the optical axis C. As a reference, the second axis P2 can be formed in a direction that intersects the first axis P1. In addition, the second movable member 300 can be formed to be coupled to some components of the second driving unit 600. For example, on one side of the second movable member 300, a second receiving portion 310 can be formed, and a second driving magnet 610 of the second driving unit 600 can be disposed on the second receiving portion 310. The second receiving portion 310 can be configured to accommodate the second driving magnet 610. For example, the internal space of the second receiving portion 310 can be formed to have dimensions and a shape that are substantially the same as those of the second driving magnet 610.

[0077] The first support member 380 is disposed between the first movable member 200 and the second movable member 300. As described above, the first support member 380 can support the first movable member 200 so that the first movable member 200 can rotate. In addition, the first support member 380 can be formed to have a predetermined height. For example, the first support member 380 can be formed to have a predetermined height in the direction of the optical axis C so that the first movable member 200 and the second movable member 300 can be disposed with a predetermined interval therebetween.

[0078] The first support member 380 can be coupled to the first movable member 200 and the second movable member 300. For example, one end of the first support member 380 can be in contact with or coupled to the first movable member 200, and the other end thereof can be coupled to the second movable member 300. The first support member 380 can be formed at intervals in one direction. For example, two first support members 380 can be formed at intervals in the minor axis direction or the width direction of the second movable member 300. Alternatively, two first support members 380 can be formed at intervals in the minor axis direction or the width direction of the fixed member 400.

[0079] The first support member 380 can be configured to enable the first movable member 200 to rotate smoothly. For example, one end of the first support member 380 can be formed to have a substantially curved surface that is in line contact with or in rolling contact with the fitting groove of the first movable member 200. The contact point or coupling point between the first support member 380 and the first movable member 200 can be substantially located on the virtual first axis P1. Therefore, the first movable member 200 can rotate about the contact point with the first support member 380. As another example, the first support member 380 can cause the first movable member 200 to rotate by elastic deformation. For example, the first support member 380 can be formed of a material that is easily elastically deformed by an external force, or can be provided with such as Figure 1The formed groove 382 is shown to facilitate bending deformation by an external force.

[0080] The fixing member 400 is disposed below the second movable member 300 and configured to support the second movable member 300. For example, the fixing member 400 may support the second movable member 300 such that the second movable member 300 can rotate via the second supporting member 480. The fixing member 400 may be configured to be coupled to the housing 800. For example, the fixing member 400 may be fixed to the inner side of the housing 800 without movement.

[0081] The second supporting member 480 is disposed between the second movable member 300 and the fixing member 400. The second supporting member 480 may support the second movable member 300 such that the second movable member 300 can rotate as described above. The second supporting member 480 may be formed to have a predetermined height. For example, the second supporting member 480 may be formed to have a predetermined height in the direction of the optical axis C such that the second movable member 300 and the fixing member 400 can be disposed at a predetermined interval.

[0082] The second supporting member 480 may be coupled to the second movable member 300 and the fixing member 400. For example, one end of the second supporting member 480 may contact or be coupled to the second movable member 300, while the other end thereof may be coupled to the fixing member 400. The second supporting members 480 may be formed at intervals in one direction. For example, two second supporting members 480 may be formed at intervals in the minor axis direction or the width direction of the fixing member 400.

[0083] The second supporting member 480 may be formed to enable the second movable member 300 to rotate smoothly. For example, one end of the second supporting member 480 may be formed to have a substantially curved surface and may be in line contact or rolling contact with the fitting groove of the second movable member 300. The contact point or the coupling point between the second supporting member 480 and the fixing member 400 may be substantially located on the virtual second axis P2. Thus, the second movable member 300 may rotate about the contact point with the second supporting member 480. As another example, the second supporting member 480 may rotate the second movable member 300 by elastic deformation. For example, the second supporting member 480 may be formed of a material that is easily elastically deformed by an external force, or as Figure 7 shown is provided with a groove 482 to facilitate bending deformation by an external force.

[0084] The first movable member 200, the second movable member 300, and the fixed member 400 may be sequentially arranged along the direction of the optical axis C. For example, the second movable member 300 may be disposed below the first movable member 200, and the fixed member 400 may be disposed below the second movable member 300. The first movable member 200, the second movable member 300, and the fixed member 400 may be arranged at a predetermined interval. For example, the first movable member 200 and the second movable member 300 are arranged at a first interval so that the first movable member 200 can rotate, and the second movable member 300 and the fixed member 400 may be arranged at a second interval so that the second movable member 300 can rotate. The first interval and the second interval may have the same size. However, the first interval and the second interval do not necessarily have to be formed to have the same size. The first movable member 200, the second movable member 300, and the fixed member 400 may have substantially the same size and shape. For example, the first movable member 200, the second movable member 300, and the fixed member 400 may be formed into a substantially quadrilateral frame shape. However, the shapes of the first movable member 200, the second movable member 300, and the fixed member 400 are not limited to the quadrilateral shape.

[0085] The first driving unit 500 may provide the driving force required to rotationally drive the first movable member 200. For example, the first driving unit 500 may provide a driving force to one side of the first movable member 200 to achieve the rotational driving of the first movable member 200. The first driving unit 500 may include a first driving magnet 510 and a first driving coil 520. The first driving magnet 510 may be disposed on the first movable member 200, and the first driving coil 520 may be disposed on the housing 800 or the first substrate 710. The first driving magnet 510 and the first driving coil 520 may be arranged to face each other. For example, the first driving coil 520 may be disposed on one side of the housing 800 to be closest to and face the first driving magnet 510.

[0086] The second driving unit 600 may provide the driving force required to rotationally drive the second movable member 300. For example, the second driving unit 600 may provide a driving force to one side of the second movable member 300 to enable the second movable member 300 to rotate. The second driving unit 600 may include a second driving magnet 610 and a second driving coil 620. The second driving magnet 610 may be disposed on the second movable member 300, and the second driving coil 620 may be disposed on the housing 800 or the first substrate 710. The second driving magnet 610 and the second driving coil 620 may be arranged to face each other. For example, the second driving coil 620 may be disposed on one side of the housing 800 to be closest to and face the second driving magnet 610.

[0087] The first driving unit 500 and the second driving unit 600 may be arranged to generate driving forces in directions intersecting each other. For example, the first driving unit 500 may be arranged near the first side of the lens module 100, and the second driving unit 600 may be arranged near the second side of the lens module 100. As another example, the first driving magnet 510 and the first driving coil 520 of the first driving unit 500 are arranged substantially parallel to the first axis P1, and the second driving magnet 610 and the second driving coil 620 of the second driving unit 600 are arranged substantially parallel to the second axis P2. Accordingly, the first driving unit 500 and the second driving unit 600 can rotate the lens module 100 in different directions to perform image stabilization.

[0088] The first substrate 710 may be connected to the first driving unit 500 and the second driving unit 600. For example, the first substrate 710 may be electrically connected to the first driving coil 520 of the first driving unit 500 and the second driving coil 620 of the second driving unit 600. The first substrate 710 may enable the control of the first driving unit 500 and the second driving unit 600. For example, the first substrate 710 is electrically connected to the second substrate 720 on which a control device is provided, and may transmit the control signal of the second substrate 720 to the first driving unit 500 and the second driving unit 600. The first substrate 710 may be configured to bend and deform. For example, the first substrate 710 may be formed of a flexible material. The first substrate 710 may be arranged on the housing 800. For example, the first substrate 710 may be arranged in the housing 800 such that the first driving coil 520 and the second driving coil 620 may be arranged in the openings 802 and 804 of the housing 800.

[0089] The second substrate 720 may be arranged on one side of the housing 800. For example, the second substrate 720 may be arranged below the housing 800. The second substrate 720 may include an image sensor 730 that converts an optical signal into an electrical signal. In addition, the second substrate 720 may further include passive components required to drive the image sensor 730 and the like. The second substrate 720 may be electrically connected to the first substrate 710. For example, the second substrate 720 may be electrically connected to the first substrate 710 through a separate member. A connector 740 connecting the camera module 10 and an electronic device (e.g., a portable terminal) may be arranged on the second substrate 720.

[0090] The housing 800 can be configured to accommodate the lens module 100, the first movable member 200, the second movable member 300, the fixed member 400, the first driving unit 500, and the second driving unit 600. For example, the housing 800 can be formed in a polyhedral shape with an accommodation space to accommodate the above components. However, the shape of the housing 800 is not limited to a polyhedron. The housing 800 can be formed to allow the setting of the first driving unit 500 and the second driving unit 600. For example, openings 802 and 804 can be formed in two different sides of the housing 800 such that the first driving coil 520 and the second driving coil 620 face the first driving magnet 510 and the second driving magnet 610.

[0091] The shield 900 can be configured to protect the main components of the camera module 10 from harmful electromagnetic waves or external impacts. For example, the shield 900 is configured to surround the outside of the housing 800. Therefore, failures of the first driving unit 500 and the second driving unit 600 due to harmful electromagnetic waves can be prevented. In addition, the shield 900 can reduce damage to the lens module 100, the first movable member 200, the second movable member 300, the fixed member 400, the first driving unit 500, the second driving unit 600, and the housing 800 due to external impacts.

[0092] The camera module 10 configured as described above has a thin structure as Figure 2 shown, and thus can be easily mounted on a portable terminal.

[0093] Next, according to an example, the operating state of the camera module will be described with reference to Figures 3 to 6 the following.

[0094] According to an example, the camera module 10 can perform image stabilization through the rotational movement or the locus movement of the lens module 100.

[0095] As an example, as Figure 3 and Figure 4 shown, the camera module 10 can correct jitter acting in the direction of the second axis P2 by rotating the lens module 100 and the first movable member 200 about the virtual first axis P1.

[0096] The rotational driving of the lens module 100 and the first movable member 200 can be performed by the first driving unit 500. For example, when jitter in the direction of the second axis P2 is detected, the control device of the camera module 10 can drive the first driving unit 500 to rotate the lens module 100 and the first movable member 200.

[0097] The first driving unit 500 can cause the lens module 100 and the first movable member 200 to rotate about a virtual first axis P1. For example, due to the interaction between the first driving magnet 510 and the first driving coil 520, the first movable member 200 can rotate clockwise or counterclockwise. The first movable member 200 can rotate about the connection point between the first movable member 200 and the first supporting member 380, or about the groove 382 of the first supporting member 380. The above connection point between the first movable member 200 and the first supporting member 380 or the groove 382 can be substantially formed on the first axis P1. The lens module 100 moves integrally with the first movable member 200. Therefore, when the first movable member 200 is driven, the lens module 100 can rotate in the same direction as the first movable member 200.

[0098] As another example, as Figure 5 and Figure 6 shown, the camera module 10 can correct jitter acting in the direction of the first axis P1 by rotating the lens module 100 and the first movable member 200 and the second movable member 300 about a virtual second axis P2.

[0099] The rotational driving of the lens module 100 and the first movable member 200 and the second movable member 300 can be performed by the second driving unit 600. For example, when jitter in the direction of the first axis P1 is detected, the control device of the camera module 10 can rotate the second movable member 300 by driving the second driving unit 600.

[0100] The second driving unit 600 can cause the second movable member 300 to rotate about a virtual second axis P2. For example, due to the interaction between the second driving magnet 610 and the second driving coil 620, the second movable member 300 can rotate clockwise or counterclockwise. The second movable member 300 can rotate about the connection point between the second movable member 300 and the second supporting member 480 or the groove 482 of the second supporting member 480. As described above, the connection point between the second movable member 300 and the second supporting member 480 or the groove 482 can be substantially formed on the second axis P2. The lens module 100 and the first movable member 200 are disposed on the second movable member 300, and thus when the second movable member 300 rotates, they can rotate in the same direction as the second movable member 300.

[0101] As another example, the camera module 10 causes the lens module 100 to rotate simultaneously about a virtual first axis P1 and a second axis P2 to correct jitter in the directions of the first axis P1 and the second axis P2. Specifically, through the movement of the first movable member 200 rotated by the first driving unit 500 and the movement of the second movable member 300 rotated by the second driving unit 600, the lens module 100 can rotate about the first axis P1 and the second axis P2. For example, the lens module 100 can rotate about the first axis P1 by the first driving unit 500 and simultaneously rotate about the second axis P2 by the second driving unit 600. As another example, the lens module 100 rotates about the first axis P1 by the first driving unit 500 and then rotates about the second axis P2 by the second driving unit 600. The rotation amounts of the lens module 100 by the first driving unit 500 and the second driving unit 600 can increase or decrease in proportion to the amount of jitter applied to the camera module 10.

[0102] When the lens module 100 rotates about the virtual first axis P1 and the second axis P2, the camera module 10 configured as described above performs image stabilization, thereby suppressing the collision phenomenon between the lens module 100 and the housing 800 and reducing the collision sound.

[0103] Reference will be made to Figures 7 to 12 describe a camera module according to another example.

[0104] First, reference will be made to Figure 7 describe the configuration of the camera module 12.

[0105] According to the example, the camera module 12 may include a lens module 100, a first movable member 200, a second movable member 300, a first support member 380, a fixed member 400, a second support member 480, a first driving unit 500, and a second driving unit 600. However, the configuration of the camera module 12 is not limited to these components. For example, the camera module 12 may further include a first substrate 710, a second substrate 720, an image sensor 730, a housing 800, a shield 900, etc.

[0106] The lens module 100 may include a lens 110, a lens barrel 120, and a barrel bracket 130. However, the configuration of the lens module 100 is not limited to the above components. For example, the lens barrel 120 and the barrel bracket 130 may be integrally formed, or the barrel bracket 130 may be omitted from the configuration of the lens module 100. The lens module 100 may include one or more lenses 110. For example, the lens module 100 may include five or more lenses 110. However, the configuration of the lens module 100 is not limited to five lenses 110. For example, the lens module 100 may include four or fewer lenses 110 or six or more lenses 110. The lens barrel 120 may be configured to align a plurality of lenses 110 in the direction of the optical axis C. For example, the lens barrel 120 may align the optical axis C of the lens 110 by contact coupling with the lens 110. The barrel bracket 130 is configured to receive the lens barrel 120. The barrel bracket 130 may be formed to facilitate the coupling between the lens module 100 and other components. For example, the barrel bracket 130 may be formed in the shape of a small planar body that facilitates contact coupling with other components.

[0107] The first movable member 200 is configured to be coupled to the lens module 100. For example, the first movable member 200 may be coupled to the barrel bracket 130 of the lens module 100. The first movable member 200 may be configured to enable rotational driving. For example, the first movable member 200 may be configured to rotate about a virtual first axis P1 that intersects the optical axis C in a state where the first movable member 200 is coupled to the lens module 100. The first movable member 200 may be formed to be coupled to some components of the first driving unit 500. For example, first receiving portions 210 (212, 214) may be formed on the first side and the second side of the first movable member 200, and first driving magnets 510 (512, 514) of the first driving unit 500 may be disposed in the first receiving portions 210 (212, 214). The first receiving portions 210 (212, 214) may be configured to accommodate the first driving magnets 510 (512, 514). For example, the internal space of the first receiving portions 210 (212, 214) may be formed to have dimensions and a shape that are substantially the same as the dimensions and shape of the first driving magnets 510 (512, 514).

[0108] The second movable member 300 may be disposed between the first movable member 200 and the fixed member 400. For example, the second movable member 300 may be located above the fixed member 400 and below the first movable member 200 at the same time. The second movable member 300 may support the first movable member 200 such that the first movable member 200 can rotate. For example, the second movable member 300 may support the first movable member 200 such that the first movable member 200 can rotate through the first support member 380. The second movable member 300 may be coupled to the first support member 380. For example, a coupling groove into which the first support member 380 is fitted may be formed in one surface of the second movable member 300.

[0109] The second movable member 300 may be configured such that rotational driving can be performed. For example, the second movable member 300 may be configured to rotate about a virtual second axis P2 that intersects the optical axis C. As a reference, the second axis P2 may be formed in a direction intersecting the first axis P1. The second movable member 300 may be formed to be coupled to some components of the second driving unit 600. For example, on the first side and the second side of the second movable member 300, second receiving portions 310 (312, 314) may be formed, and second driving magnets 610 (612, 614) of the second driving unit 600 may be disposed in the second receiving portions 310 (312, 314). The second receiving portions 310 (312, 314) may be configured to accommodate the second driving magnets 610 (612, 614). For example, the internal space of the second receiving portions 310 (312, 314) may be formed to have dimensions and a shape substantially the same as those of the second driving magnets 610 (612, 614). The second receiving portions 310 (312, 314) may be formed at positions that do not overlap with the first receiving portions 210 (212, 214). For example, the second receiving portion 312 is formed side by side with the first receiving portion 212 to face the same side of the lens module 100. The second receiving portion 314 and the first receiving portion 214 may be formed to face different sides of the lens module 100.

[0110] The first support member 380 is disposed between the first movable member 200 and the second movable member 300. As described above, the first support member 380 may support the first movable member 200 such that the first movable member 200 can rotate. In addition, the first support member 380 may be formed to have a predetermined height. For example, the first support member 380 may be formed at a predetermined height in the direction of the optical axis C such that the first movable member 200 and the second movable member 300 can be disposed at a predetermined interval.

[0111] The first support member 380 may be coupled to the first movable member 200 and the second movable member 300. For example, one end of the first support member 380 may contact or be coupled to the first movable member 200, while the other end thereof may be coupled to the second movable member 300. Additionally, the first support members 380 may be formed at intervals in one direction. For example, two first support members 380 may be formed at intervals in the longitudinal axis direction or the diagonal direction of the second movable member 300. Alternatively, two first support members 380 may be formed at intervals in the longitudinal axis direction or the diagonal direction of the fixed member 400.

[0112] The first support member 380 may be formed to enable the first movable member 200 to rotate smoothly. For example, one end of the first support member 380 may be formed to have a substantially curved surface that is in line contact or rolling contact with the fitting groove of the first movable member 200. The contact point or coupling point between the first support member 380 and the first movable member 200 may be substantially located on the virtual first axis P1. Thus, the first movable member 200 may rotate about the contact point with the first support member 380. As another example, the first support member 380 may cause the first movable member 200 to rotate through elastic deformation. For example, the first support member 380 may be formed of a material that is easily elastically deformed by an external force, or provided with grooves 382 formed as shown Figure 7 so as to facilitate bending deformation by an external force.

[0113] The fixed member 400 is disposed below the second movable member 300 and configured to support the second movable member 300. For example, the fixed member 400 may support the second movable member 300 such that the second movable member 300 can rotate via the second support member 480. Additionally, the fixed member 400 may be configured to be coupled to the housing 800. For example, the fixed member 400 may be fixed to the inside of the housing 800 without moving therein.

[0114] The second support member 480 is disposed between the second movable member 300 and the fixed member 400. The second support member 480 may support the second movable member 300 such that the second movable member 300 can rotate as described above. The second support member 480 may be formed to have a predetermined height. For example, the second support member 480 may be formed at a predetermined height in the direction of the optical axis C such that the second movable member 300 and the fixed member 400 can be disposed at a predetermined interval.

[0115] The second support member 480 may be coupled to the second movable member 300 and the fixed member 400. For example, one end of the second support member 480 may contact or be coupled to the second movable member 300, and the other end thereof may be coupled to the fixed member 400. In addition, the second support members 480 may be formed at intervals in one direction. For example, two second support members 480 may be formed at intervals in the major axis direction or the diagonal direction of the fixed member 400.

[0116] The second support member 480 may be formed so as to smoothly perform the rotational driving of the second movable member 300. For example, one end of the second support member 480 may be formed to have a substantially curved surface that is in line contact or rolling contact with the fitting groove of the second movable member 300. The contact point or coupling point between the second support member 480 and the fixed member 400 may be substantially located on the virtual second axis P2. Accordingly, the second movable member 300 may rotate about the contact point with the second support member 480. As another example, the second support member 480 may rotate the second movable member 300 by elastic deformation. For example, the second support member 480 may be formed of a material that is easily elastically deformed by an external force, or provided with a groove 482 to facilitate bending deformation by an external force.

[0117] The first movable member 200, the second movable member 300, and the fixed member 400 may be sequentially arranged in the direction of the optical axis C. For example, the second movable member 300 may be disposed below the first movable member 200, and the fixed member 400 may be disposed below the second movable member 300. The first movable member 200, the second movable member 300, and the fixed member 400 may be arranged at a predetermined interval. For example, the first movable member 200 and the second movable member 300 are arranged at a first interval so that the first movable member 200 can rotate, and the second movable member 300 and the fixed member 400 may be arranged at a second interval so that the second movable member 300 can rotate. The first interval and the second interval may have the same size. However, the first interval and the second interval do not necessarily have the same size. The first movable member 200, the second movable member 300, and the fixed member 400 may be formed to have substantially the same size and shape. For example, the first movable member 200, the second movable member 300, and the fixed member 400 may be formed to have a substantially quadrilateral frame shape. However, the shapes of the first movable member 200, the second movable member 300, and the fixed member 400 are not limited to the quadrilateral shape.

[0118] The first driving unit 500 can provide the driving force required to rotationally drive the first movable member 200. For example, the first driving unit 500 can provide a driving force to one side of the first movable member 200 so as to rotationally drive the first movable member 200. The first driving unit 500 may include a first driving magnet 510 (512, 514) and a first driving coil 520 (522, 524). The first driving magnet 510 (512, 514) may be disposed on the first movable member 200, and the first driving coil 520 (522, 524) may be disposed on the housing 800 or the first substrate 710. The first driving magnet 510 (512, 514) and the first driving coil 520 (522, 524) may be arranged to face each other. For example, the first driving coil 520 (522, 524) may be disposed in the first opening 802 and the second opening 804 of the housing 800 so as to be closest to the first driving magnet 510 (512, 514) and face the first driving magnet 510 (512, 514).

[0119] The second driving unit 600 can provide the driving force required to rotationally drive the second movable member 300. For example, the second driving unit 600 can provide a driving force to one side of the second movable member 300 so that the second movable member 300 can rotate. The second driving unit 600 may include a second driving magnet 610 (612, 614) and a second driving coil 620 (622, 624). The second driving magnet 610 (612, 614) may be disposed on the second movable member 300, and the second driving coil 620 may be disposed on the housing 800 or the first substrate 710. In addition, the second driving magnet 610 (612, 614) and the second driving coil 620 (622, 624) may be arranged to face each other. For example, the second driving coil 620 (622, 624) may be disposed in the first opening 802 and the third opening 806 so as to be closest to the second driving magnet 610 (612, 614) and face the second driving magnet 610 (612, 614).

[0120] The first driving unit 500 and the second driving unit 600 may be arranged to generate driving forces in directions intersecting each other. For example, the first driving unit 500 may be disposed adjacent to the first side and the second side of the lens module 100, and the second driving unit 600 may be disposed adjacent to the first side and the third side of the lens module 100. As another example, the first driving magnet 510 and the first driving coil 520 of the first driving unit 500 may be disposed on one side of the first axis P1, and the second driving magnet 610 and the second driving coil 620 of the second driving unit 600 may be disposed on one side of the second axis P2. Therefore, the first driving unit 500 and the second driving unit 600 can rotate the lens module 100 in different directions to perform image stabilization of the camera module.

[0121] Parts of the first driving unit 500 and the second driving unit 600 may be arranged to provide driving forces to the same side of the lens module 100. For example, the first driving magnet 512 of the first driving unit 500 and the second driving magnet 612 of the second driving unit 600 may be arranged to face the same side, e.g., the first side of the lens module 100, respectively, and the first driving coil 522 of the first driving unit 500 and the second driving coil 622 of the second driving unit 600 interact with the first driving magnet 512 and the second driving magnet 612 to provide a driving force to the first side of the lens module 100.

[0122] The first substrate 710 may be connected to the first driving unit 500 and the second driving unit 600. For example, the first substrate 710 may be electrically connected to the first driving coil 520 of the first driving unit 500 and the second driving coil 620 of the second driving unit 600. The first substrate 710 may enable control of the first driving unit 500 and the second driving unit 600. For example, the first substrate 710 is electrically connected to the second substrate 720 provided with a control device and may transmit the control signals of the second substrate 720 to the first driving unit 500 and the second driving unit 600. The first substrate 710 may be configured to bend and deform. For example, the first substrate 710 may be formed of a flexible material. The first substrate 710 may be provided on the housing 800. For example, the first substrate 710 may be provided on the housing 800 such that the first driving coil 520 and the second driving coil 620 may be provided in the openings 802, 804, 806 of the housing 800.

[0123] The second substrate 720 may be provided on one side of the housing 800. For example, the second substrate 720 may be provided below the housing 800. The second substrate 720 may include an image sensor 730 for converting an optical signal into an electrical signal. In addition, the second substrate 720 may further include passive components and the like required to drive the image sensor 730. The second substrate 720 may be electrically connected to the first substrate 710. For example, the second substrate 720 may be electrically connected to the first substrate 710 through a separate component. A connector 740 connecting the camera module 12 and an electronic device (e.g., a portable terminal) may be provided on the second substrate 720.

[0124] The housing 800 can be configured to accommodate the lens module 100, the first movable member 200, the second movable member 300, the fixed member 400, the first driving unit 500, and the second driving unit 600. For example, the housing 800 can be formed to have a polyhedral shape that has an accommodation space to accommodate the above components. However, the shape of the housing 800 is not limited to a polyhedron. The housing 800 can be formed to allow the setting of the first driving unit 500 and the second driving unit 600. For example, the openings 802, 804, and 806 can be formed in two different side surfaces of the housing 800 in such a way that the first driving coil 520 and the second driving coil 620 can be set to face the first driving magnet 510 and the second driving magnet 610.

[0125] The shielding cover 900 can be configured to protect the main components of the camera module 12 from harmful electromagnetic waves or external impacts. For example, the shielding cover 900 can be configured to surround the outside of the housing 800 to prevent the first driving unit 500 and the second driving unit 600 from malfunctioning due to harmful electromagnetic waves. In addition, the shielding cover 900 can reduce damage to the lens module 100, the first movable member 200, the second movable member 300, the fixed member 400, the first driving unit 500, the second driving unit 600, and the housing 800.

[0126] As Figure 8 shown, the camera module 12 configured as described above has a thin structure and can therefore be easily mounted on a portable terminal.

[0127] Next, according to an example, the operating state of the camera module will be described with reference to Figures 9 to 12 the following.

[0128] According to an example, the camera module 12 can perform image stabilization through the rotational movement or the locus movement of the lens module 100.

[0129] As an example, as Figure 9 and Figure 10 shown, the camera module 12 is configured to rotate the lens module 100 and the first movable member 200 about a virtual first axis P1, thereby correcting the shake acting in the direction of the second axis P2.

[0130] The rotational driving of the lens module 100 and the first movable member 200 can be performed by the first driving unit 500. For example, when shake in the direction of the second axis P2 is detected, the control device of the camera module 12 drives the first driving unit 500 to rotate the lens module 100 and the first movable member 200.

[0131] The first driving unit 500 can cause the lens module 100 and the first movable member 200 to rotate about a virtual first axis P1. For example, due to the interaction between the first driving magnet 510 and the first driving coil 520, the first movable member 200 can rotate clockwise or counterclockwise. The first movable member 200 can rotate about the connection point between the first movable member 200 and the first support member 380 or the groove 382 of the first support member 380. The connection point between the first movable member 200 and the first support member 380 or the groove 382 can be substantially formed on the first axis P1. The lens module 100 moves integrally with the first movable member 200, and thus when the first movable member 200 is driven, the lens module 100 rotates in the same direction as the first movable member 200.

[0132] As another example, as Figure 11 and Figure 12 shown, the camera module 12 can be configured to cause the lens module 100 and the movable members 200 and 300 to rotate about a virtual second axis P2, and can correct the shake acting in the direction of the first axis P1.

[0133] The rotational driving of the lens module 100 and the movable members 200 and 300 can be performed by the second driving unit 600. For example, when shake in the direction of the first axis P1 is detected, the control device of the camera module 12 can cause the second movable member 300 to rotate by driving the second driving unit 600.

[0134] The second driving unit 600 can cause the second movable member 300 to rotate about a virtual second axis P2. For example, due to the interaction between the second driving magnet 610 and the second driving coil 620, the second movable member 300 can rotate clockwise or counterclockwise. In addition, the second movable member 300 can rotate about the joint point between the second movable member 300 and the second support member 480 or the groove 482 of the second support member 480. The connection point between the second movable member 300 and the second support member 480 or the groove 482 can be substantially formed on the second axis P2. The lens module 100 and the first movable member 200 are provided on the second movable member 300, and thus can rotate in the same direction together with the second movable member 300.

[0135] As another example, the camera module 12 causes the lens module 100 to rotate simultaneously about a virtual first axis P1 and a second axis P2 to correct for jitter in the directions of the first axis P1 and the second axis P2. Specifically, the lens module 100 can rotate about the first axis P1 and the second axis P2 by the movement of a first movable member 200 rotated by a first driving unit 500 and the movement of a second movable member 300 rotated by a second driving unit 600. For example, the lens module 100 can rotate about the first axis P1 by the first driving unit 500 while rotating about the second axis P2 by the second driving unit 600. As another example, the lens module 100 can rotate about the first axis P1 by the first driving unit 500 and then rotate about the second axis P2 by the second driving unit 600. The amount of rotation of the lens module 100 by the first driving unit 500 and the second driving unit 600 can increase or decrease in proportion to the amount of jitter applied to the camera module 12.

[0136] When the lens module 100 rotates about the virtual first axis P1 and the second axis P2, the camera module 12 configured as described above performs jitter correction, thereby suppressing the collision phenomenon between the lens module 100 and the housing 800 and reducing the collision sound. Further, according to this example, the camera module 12 is configured such that the first driving unit 500 and the second driving unit 600 provide driving forces to a plurality of sides of the lens module 100, thereby performing image anti-shake quickly and accurately.

[0137] According to another example, reference will be made to Figures 13 to 16 describe the camera module.

[0138] According to the example, the camera module 14 may include a lens module 100, a movable member 300, a first support member 380, a fixed member 400, a second support member 480, a first driving unit 500, and a second driving unit 600. However, the configuration of the camera module 14 is not limited to these members. For example, the camera module 14 may further include a first substrate 710, a second substrate 720, an image sensor 730, a housing 800, a shield 900, and the like.

[0139] The lens module 100 may include a lens 110, a lens barrel 120, and a barrel bracket 130. However, the configuration of the lens module 100 is not limited to the above components. For example, the lens barrel 120 and the barrel bracket 130 may be integrally formed, or the barrel bracket 130 may be omitted from the configuration of the lens module 100. The lens module 100 may include one or more lenses 110. For example, the lens module 100 may include five or more lenses 110. However, the configuration of the lens module 100 is not limited to five lenses 110. For example, the lens module 100 may include four or fewer lenses 110 or six or more lenses 110. The lens barrel 120 may be configured to align a plurality of lenses 110 in the direction of the optical axis C. For example, the lens barrel 120 may align the optical axis C of the lens 110 by contact coupling with the lens 110. The barrel bracket 130 is configured to receive the lens barrel 120. The barrel bracket 130 may be formed to facilitate the coupling between the lens module 100 and other components. For example, the barrel bracket 130 may be formed in the shape of a small planar body that facilitates contact coupling with other components.

[0140] The lens module 100 may be configured to enable rotational driving. For example, the lens module 100 may be configured to rotate about a virtual first axis P1 that intersects the optical axis C. The lens module 100 may be formed in combination with some components of the first driving unit 500. For example, a first receiving portion 132 on which the first driving magnet 510 of the first driving unit 500 may be provided may be formed on one side of the lens module 100. The first receiving portion 132 may be configured to accommodate the first driving magnet 510. For example, the internal space of the first receiving portion 132 may be formed to have substantially the same dimensions and shape as the dimensions and shape of the first driving magnet 510.

[0141] A movable member 300 may be provided between the lens module 100 and the fixed member 400. The movable member 300 may support the lens module 100 so as to enable rotational driving of the lens module 100. For example, the movable member 300 may support the lens module 100 that rotates through the first support member 380. In addition, the movable member 300 may be coupled to the first support member 380. For example, a coupling groove into which the first support member 380 is assembled may be formed in one surface of the movable member 300.

[0142] The movable member 300 can be configured to enable rotational driving. For example, the movable member 300 can be configured to rotate about a virtual second axis P2 that intersects the optical axis C. As a reference, the second axis P2 can be formed in a direction that intersects the first axis P1. In addition, the movable member 300 can be formed to be coupled to some components of the second driving unit 600. For example, on one side of the movable member 300, a second receiving portion 310 can be formed, and the second driving magnet 610 of the second driving unit 600 can be disposed on the second receiving portion 310. The second receiving portion 310 can be configured to accommodate the second driving magnet 610. For example, the internal space of the second receiving portion 310 can be formed to have dimensions and a shape that are substantially the same as those of the second driving magnet 610.

[0143] The first support member 380 is disposed between the lens module 100 and the second movable member 300. As described above, the first support member 380 can support the lens module 100 so that the lens module 100 can rotate. In addition, the first support member 380 can be formed to have a predetermined height. For example, the first support member 380 can be formed at a predetermined height in the direction of the optical axis C so that the lens module 100 and the second movable member 300 can be disposed at a predetermined interval.

[0144] The first support member 380 can be coupled to the lens module 100 and the movable member 300. For example, one end of the first support member 380 can contact or be coupled to the lens module 100, and the other end of the first support member 380 can be coupled to the movable member 300. In addition, the first support member 380 can be formed at intervals in one direction. For example, two first support members 380 can be formed at intervals in the short-axis direction or the width direction of the movable member 300. Alternatively, two first support members 380 can be formed at intervals in the short-axis direction or the width direction of the fixed member 400.

[0145] The first support member 380 can be formed such that the lens module 100 can rotate smoothly. For example, one end of the first support member 380 can be formed to have a substantially curved surface that is in line contact or rolling contact with the fitting groove of the lens module 100. The contact point or coupling point between the first support member 380 and the lens module 100 can be substantially located on the virtual first axis P1. Therefore, the lens module 100 can rotate about the contact point with the first support member 380. As another example, the first support member 380 can cause the lens module 100 to rotate by elastic deformation. For example, the first support member 380 can be formed of a material that is easily elastically deformed by an external force, or is provided with a groove 382 formed as shown in Figure 13 order to facilitate bending deformation by an external force.

[0146] The fixed member 400 is disposed below the movable member 300 and configured to support the movable member 300. For example, the fixed member 400 may support the movable member 300 such that the movable member 300 can rotate via the second support member 480. In addition, the fixed member 400 may be configured to be coupled to the housing 800. For example, the fixed member 400 may be fixed to the inside of the housing 800 without movement.

[0147] The second support member 480 is disposed between the movable member 300 and the fixed member 400. The second support member 480 may support the movable member 300 such that the movable member 300 can rotate as described above. In addition, the second support member 480 may be formed to have a predetermined height. For example, the second support member 480 may be formed in the direction of the optical axis C with a predetermined height such that the movable member 300 and the fixed member 400 can be disposed at a predetermined interval.

[0148] The second support member 480 may be coupled to the movable member 300 and the fixed member 400. For example, one end of the second support member 480 may contact or be coupled to the movable member 300, and the other end of the second support member 480 may be coupled to the fixed member 400. In addition, the second support member 480 may be formed at intervals in one direction. For example, two second support members 480 may be formed at intervals in the minor axis direction or the width direction of the fixed member 400.

[0149] The second support member 480 may be formed such that the movable member 300 can rotate smoothly. For example, one end of the second support member 480 may be formed to have a substantially curved surface that is in line contact or rolling contact with the fitting groove of the movable member 300. The contact point or the coupling point between the second support member 480 and the fixed member 400 may be substantially located on the virtual second axis P2. Thus, the movable member 300 can rotate about the contact point with the second support member 480. As another example, the second support member 480 may cause the movable member 300 to rotate by elastic deformation. For example, the second support member 480 may be formed of a material that is easily elastically deformed by an external force, or provided with a groove 482 formed as shown in Figure 13 order to facilitate bending deformation by an external force.

[0150] The lens module 100, the movable member 300, and the fixed member 400 may be sequentially arranged in the direction of the optical axis C. For example, the movable member 300 may be disposed below the lens module 100, and the fixed member 400 may be disposed below the movable member 300. In addition, the lens module 100, the movable member 300, and the fixed member 400 may be arranged at a predetermined interval. For example, the lens module 100 and the movable member 300 may be arranged at a first interval so that the lens module 100 can rotate, and the movable member 300 and the fixed member 400 may be arranged at a second interval so that the movable member 300 can be rotationally driven. The first interval and the second interval may have the same size. However, the first interval and the second interval do not necessarily have the same size. The movable member 300 and the fixed member 400 may be formed to have substantially the same size and shape. For example, the movable member 300 and the fixed member 400 may be formed to have a substantially quadrilateral frame shape. However, the shapes of the movable member 300 and the fixed member 400 are not limited to the quadrilateral shape.

[0151] The first driving unit 500 may provide the driving force required to rotationally drive the lens module 100. For example, the first driving unit 500 may provide a driving force to one side of the lens module 100 so that the lens module 100 can be rotationally driven. The first driving unit 500 may include a first driving magnet 510 and a first driving coil 520. The first driving magnet 510 may be disposed on the lens module 100, and the first driving coil 520 may be disposed on the housing 800 or the first substrate 710. The first driving magnet 510 and the first driving coil 520 may be arranged to face each other. For example, the first driving coil 520 may be disposed on one side of the housing 800 to be closest to the first driving magnet 510 and face the first driving magnet 510.

[0152] The second driving unit 600 may provide the driving force required to rotationally drive the movable member 300. For example, the second driving unit 600 may provide a driving force to one side of the movable member 300 so that the movable member 300 can rotate. The second driving unit 600 may include a second driving magnet 610 and a second driving coil 620. The second driving magnet 610 may be disposed on the movable member 300, and the second driving coil 620 may be disposed on the housing 800 or the first substrate 710. In addition, the second driving magnet 610 and the second driving coil 620 may be arranged to face each other. For example, the second driving coil 620 may be disposed on one side of the housing 800 to be closest to the second driving magnet 610 and face the second driving magnet 610.

[0153] The first driving unit 500 and the second driving unit 600 may be arranged to generate driving forces in directions intersecting each other. For example, the first driving unit 500 may be arranged near the first side of the lens module 100, and the second driving unit 600 may be arranged near the second side of the lens module 100. As another example, the first driving magnet 510 and the first driving coil 520 of the first driving unit 500 may be arranged substantially parallel to the first axis P1, and the second driving magnet 610 and the second driving coil 620 of the second driving unit 600 may be arranged substantially parallel to the second axis P2. Accordingly, the first driving unit 500 and the second driving unit 600 may drive the lens module 100 to rotate in different directions to perform image stabilization.

[0154] The first substrate 710 may be connected to the first driving unit 500 and the second driving unit 600. For example, the first substrate 710 may be electrically connected to the first driving coil 520 of the first driving unit 500 and the second driving coil 620 of the second driving unit 600. The first substrate 710 may enable control of the first driving unit 500 and the second driving unit 600. For example, the first substrate 710 may be electrically connected to the second substrate 720 provided with a control device to transmit the control signal of the second substrate 720 to the first driving unit 500 and the second driving unit 600. The first substrate 710 may be configured to bend and deform. For example, the first substrate 710 may be formed of a flexible material. The first substrate 710 may be arranged on the housing 800. For example, the first substrate 710 may be arranged on the housing 800 such that the first driving coil 520 and the second driving coil 620 are arranged in the openings 802 and 804 of the housing 800.

[0155] The second substrate 720 may be arranged on one side of the housing 800. For example, the second substrate 720 may be arranged below the housing 800. The second substrate 720 may include an image sensor 730 for converting an optical signal into an electrical signal. In addition, the second substrate 720 may further include passive components and the like required to drive the image sensor 730. The second substrate 720 may be electrically connected to the first substrate 710. For example, the second substrate 720 may be electrically connected to the first substrate 710 through a separate member. A connector 740 for connecting the camera module 14 and an electronic device (e.g., a portable terminal) may be arranged on the second substrate 720.

[0156] The housing 800 can be configured to accommodate the lens module 100, the movable member 300, the fixed member 400, the first driving unit 500, and the second driving unit 600. For example, the housing 800 can be formed in a polyhedral shape having an accommodation space to accommodate the above components. However, the shape of the housing 800 is not limited to a polyhedron. The housing 800 can be formed to allow the first driving unit 500 and the second driving unit 600 to be provided. For example, openings can be formed in two different side surfaces of the housing 800 such that the first driving coil 520 and the second driving coil 620 can face the first driving magnet 510 and the second driving magnet 610.

[0157] The shield 900 can be configured to protect the main components of the camera module 14 from harmful electromagnetic waves or external impacts. For example, the shield 900 is configured to surround the outside of the housing 800 to prevent the first driving unit 500 and the second driving unit 600 from malfunctioning due to harmful electromagnetic waves. In addition, the shield 900 can reduce damage to the lens module 100, the movable member 300, the fixed member 400, the first driving unit 500, the second driving unit 600, and the housing 800 due to external impacts.

[0158] As Figure 14 shown, the camera module 14 configured as above has a thin structure and can thus be easily mounted on a portable terminal.

[0159] Next, according to another example, the operating state of the camera module will be described with reference to Figures 15 to 18 the following.

[0160] According to the example, the camera module 14 can perform image stabilization through the rotational movement or the locus movement of the lens module 100.

[0161] As an example, as Figure 15 and Figure 16 shown, the camera module 14 can correct the shake acting in the direction of the second axis P2 by rotating the lens module 100 about the virtual first axis P1.

[0162] The rotational driving of the lens module 100 can be performed by the first driving unit 500. For example, when shake in the direction of the second axis P2 is detected, the control device of the camera module 14 can drive the first driving unit 500 to rotate the lens module 100.

[0163] The first driving unit 500 can rotate the lens module 100 about a virtual first axis P1. For example, due to the interaction between the first driving magnet 510 and the first driving coil 520, the lens module 100 can rotate clockwise or counterclockwise. The lens module 100 can rotate about a connection point with the first support member 380 or the groove 382 of the first support member 380. The connection point between the lens module 100 and the first support member 380 or the groove 382 can be substantially formed on the first axis P1.

[0164] As another example, as Figure 17 and Figure 18 shown, the camera module 14 can correct jitter acting in the direction of the first axis P1 by rotating the lens module 100 and the movable member 300 about a virtual second axis P2.

[0165] The rotational driving of the lens module 100 and the movable member 300 can be performed by the second driving unit 600. For example, when jitter in the direction of the first axis P1 is detected, the control device of the camera module 14 can drive the second driving unit 600 to rotate the movable member 300.

[0166] The second driving unit 600 can rotate the movable member 300 about a virtual second axis P2. For example, due to the interaction between the second driving magnet 610 and the second driving coil 620, the movable member 300 can rotate clockwise or counterclockwise. In addition, the movable member 300 can rotate about a connection point with the second support member 480 or the groove 482 of the second support member 480. The connection point between the movable member 300 and the second support member 480 or the groove 482 can be substantially formed on the second axis P2. The lens module 100 is disposed on the second movable member 300, and thus when the movable member 300 is driven to rotate, the lens module 100 can rotate in the same direction as the movable member 300.

[0167] As another example, the camera module 14 may correct jitters in the directions of the first axis P1 and the second axis P2 by rotating the lens module 100 simultaneously about the virtual first axis P1 and the second axis P2. Specifically, the lens module 100 may rotate about the first axis P1 and the second axis P2 by the movement of the first movable member 200 rotated by the first driving unit 500 and the movement of the movable member 300 rotated by the second driving unit 600. For example, the lens module 100 may rotate about the first axis P1 by the first driving unit 500 and simultaneously rotate about the second axis P2 by the second driving unit 600. As another example, the lens module 100 may rotate about the first axis P1 by the first driving unit 500 and then rotate about the second axis P2 by the second driving unit 600. The rotation amounts of the lens module 100 by the first driving unit 500 and the second driving unit 600 may increase or decrease in proportion to the amount of jitter applied to the camera module 14.

[0168] When the lens module 100 rotates about the virtual first axis P1 and the second axis P2, the camera module 14 configured as above performs image stabilization. Accordingly, collisions between the lens module 100 and the housing can be suppressed, and collision sounds can be reduced. In addition, in the case of the camera module 14, according to this example, the number of components required to perform the image stabilization function can be simplified, and thus the manufacturing cost of the camera module 14 can be reduced.

[0169] As described above, according to the example, the camera module can significantly reduce damage to the lens module or failure of the camera module due to external shocks.
