[0045] In one or more examples, the camera module can reduce or prevent the drive magnet (the main component of the drive device) from separating due to external shocks and vibrations.

[0046] The camera module in the exemplary embodiments can be mounted on an electronic device. For example, by way of example only, the camera module can be mounted on a portable terminal, a laptop computer, a virtual reality (VR) device, VR glasses, etc. However, the electronic devices on which the camera module can be mounted are not limited to the above-described devices. For example, the camera module can be mounted on a portable electronic device such as a portable game console.

[0047] The exemplary camera module can be configured to address the problem of separation of the drive device due to external impact, drop impact, or vibration. For example, the camera module can be configured to address the problem of the drive magnet of the drive device separating from the movable part due to impact or vibration. Additionally, the camera module in the exemplary embodiment can be configured to reduce damage caused by collisions between internal components.

[0048] To address the aforementioned problems, a camera module according to one or more embodiments may include a reinforcing member integrated with a lens barrel and a movable frame. The reinforcing member may be integrated with the lens barrel or movable frame via insertion injection or double injection. The reinforcing member may be configured to support a drive magnet. For example, the main body portion of the reinforcing member may extend along the length of the drive magnet and may contact the surface of the drive magnet.

[0049] The reinforcing member according to one or more embodiments can be configured to reduce deformation or damage to the lens barrel and the movable frame. For example, the reinforcing member can increase the stiffness of the lens barrel and the movable frame by means of one or more protrusions extending from the main body in different directions.

[0050] In the following, exemplary embodiments of the camera module will be described in detail with reference to the accompanying drawings.

[0051] First, refer to Figures 1 to 8 Describes a camera module according to one or more embodiments.

[0052] A camera module 10 according to one or more embodiments may include a housing 100, a lens barrel support 300, a lens barrel 400, a drive device 500, and a reinforcing member 710. However, the components of the camera module 10 are not limited to the above-described components. For example, the camera module 10 may also include a substrate 540 on which an image sensor 560 is mounted.

[0053] The housing 100 can be configured to house the main components of the camera module 10. For example, the housing 100 can house the lens barrel support 300, the lens barrel 400, and the drive device 500 within a housing space 102 formed therein. The housing space 102 can be formed in an open shape along the optical axis C. The housing space 102 allows the lens barrel support 300 and the lens barrel 400 to move. For example, the housing space 102 can be formed to have a large size, making it possible for the lens barrel support 300 and the lens barrel 400 to move in the direction of the optical axis C or in a direction intersecting the optical axis C.

[0054] The housing 100 can be configured to house the drive device 500. For example, one side of the housing 100 can be open, or a support structure of a predetermined shape can be formed on one side of the housing 100 to house a portion of a component of the drive device 500 (e.g., a drive coil). However, the aforementioned support structure is not necessarily formed on one side of the housing 100. For example, a portion of a component of the drive device 500 can be secured to the housing 100 by fastening or adhesive means. Furthermore, since the term "housing 100" as used herein can encompass all components configured to house the lens barrel support 300 and the lens barrel 400, the term can also refer to components or techniques configured to house another type of component or technique.

[0055] The term is replaced by another term. For example, the housing 100 in the exemplary embodiment may be the same component as the outer shell, container, or support portion 5.

[0056] The lens barrel support 300 can be configured to be coupled to the lens barrel 400. For example, the lens barrel support 300 may include an opening 302 for connection to the lens barrel 400. The opening 302 may have a shape and size substantially the same as the cross-section of the lens barrel 400. Therefore, the lens...

[0057] The lens barrel 400 can be securely fixed to the opening 302 of the lens barrel support 300. However, the connection between the lens barrel support 300 and the lens barrel 400 is not limited to a connection by insertion. For example, for

[0058] To securely connect the lens barrel support 300 and the lens barrel 400, adhesive can be injected into the connection between the lens barrel support 300 and the lens barrel 400, or alternatively, a heat source such as a laser can be used to fuse the lens barrel support 300 and the lens barrel 400 together.

[0059] The lens barrel support 300 may include a component that supports or accommodates a portion of a component of the drive device 500 (e.g., a drive magnet). For example, a mounting portion 304 accommodating a portion of the drive device 500 may be formed on a side surface of the lens barrel support 300. The mounting portion 304 may be sized to accommodate the drive magnet of the drive device 500. However, the mounting portion 304 need not be formed on a side surface of the lens barrel support 300.

[0060] On the surface. Meanwhile, the lens barrel support 300 described herein may include all components configured to be integrally driven with the lens barrel 4000, and is not limited to this terminology. For example, in an exemplary embodiment...

[0061] The lens barrel support 300 can be the same as the lens support and lens holder.

[0062] The lens barrel 400 may include lenses L. For example, the lens barrel 400 may include one or more lenses L arranged sequentially along the optical axis C. The lens barrel 400 may be configured to...

[0063] The incident light is imaged onto the image sensor 560. As a specific example, light incident through lens L of the lens barrel 4005 can be imaged onto the image sensor 560.

[0064] This includes devices for adjusting the amount of incident light. For example, the lens barrel 400 may also include an aperture stop (not shown) disposed on the object side of the foremost lens or between the lenses. Meanwhile, Figure 1 The lens barrel 400 shown can have an almost cylindrical shape, but the external shape of the lens barrel 400...

[0065] The shape is not limited to a cylindrical shape. For example, the lens barrel 400 can be configured to have a hexahedral shape.

[0066] The driving device 500 can be configured to drive the lens barrel support 300 and the lens barrel 400. For example, the driving device 500 can drive the lens barrel support 300 and the lens barrel 400 in the direction of the optical axis C. The driving device 500 may include a driving magnet 510 and a driving coil 520. However, the components of the driving device 500 are not limited to the driving magnet 510 and the driving coil 520.

[0067] The driving device 500 can be disposed in the housing 100 and the lens barrel support 300. For example, a driving magnet 510 can be disposed on the lens barrel support 300, and a driving coil 520 can be disposed on the housing 100. The driving magnet 510 and the driving coil 520 can be arranged opposite each other. For example, the driving magnet 510 can be disposed on one surface of the lens barrel support 300, and the driving coil 520 can be disposed on the inner surface of the housing 100 opposite to the driving magnet 510. Meanwhile, in the accompanying drawings, a single driving magnet 510 and a single driving coil 520 can be disposed separately in the lens barrel support 300 and the housing 100, but if necessary, two or more driving magnets 510 and two or more driving coils 520 can be disposed in the lens barrel support 300 and the housing 100.

[0068] The drive device 500 can be securely fixed to the lens barrel support 300 and the housing 100. For example, the drive magnet 510 can be integrated with the lens barrel support 300, or it can be securely fixed to the lens barrel support 300 via a reinforcing member 710. The drive coil 520 can be fixed to the housing 100 via a substrate. For example, the drive coil 520 can be attached to the inner surface of the housing 100 via a flexible substrate. As another example, the drive coil 520 can be integrated with the housing 100 via a molded interconnect device (MID) method.

[0069] The reinforcing member 710 can be integrated with the lens barrel support 300. For example, the reinforcing member 710 can be integrated with the lens barrel support 300 by insertion injection or double injection. The reinforcing member 710 can be configured to increase the stiffness of the lens barrel support 300. For example, the reinforcing member 710 can be formed of a material with high strength and stiffness, thereby increasing the stiffness of weak parts of the lens barrel support 300. The reinforcing member 710 can be configured to support the drive magnet 510. For example, as... Figure 2 As shown, the reinforcing member 710 can be configured to support one surface of the drive magnet 510.

[0070] In the following text, reference will be made to Figure 3 The structure of the reinforcing member 710 is described in more detail.

[0071] In a non-limiting example, the reinforcing member 710 may be formed of a material having predetermined elasticity and stiffness. For example, the reinforcing member 710 may be formed of a metallic material. However, the material of the reinforcing member 710 is not limited to metal. The reinforcing member 710 may include a main body portion 712, a first protrusion 714, and a second protrusion 716. However, the components of the reinforcing member 710 are not limited to the main body portion 712, the first protrusion 714, and the second protrusion 716. For example, a third protrusion may also be formed on the side surface of the reinforcing member 710. The main body portion 712, the first protrusion 714, and the second protrusion 716 of the reinforcing member 710 may be integrated together with each other through a series of processes. For example, the reinforcing member 710 may be rapidly formed by a stamping process in a single process. However, the method of forming the reinforcing member 710 is not limited to a stamping process.

[0072] The main body portion 712 can be configured to increase the torsional stiffness of the lens barrel support 300. For example, the main body portion 712 can extend in a plane direction parallel to the optical axis C, and can prevent or reduce torsional deformation of the lens barrel support 300. The main body portion 712 can be formed to have a considerable length. For example, the length TD of the main body portion 712 can be greater than or equal to the length ML of the drive magnet 510. As another example, the length TD of the main body portion 712 can be less than or equal to the length BHL of the lens barrel support 300 in one lateral direction. However, the length TD of the main body portion 712 is not limited to the above dimensional relationships. The main body portion 712 can have a predetermined height Th. For example, the height Th of the main body portion 712 can be greater than or equal to the height Mh of the drive magnet 510. As another example, the height Th of the main body portion 712 can be less than the height BHh of the lens barrel support 300. However, the height Th of the main body portion 712 is not limited to the above dimensional relationships.

[0073] A groove 7122 can be formed in the main body portion 712. The groove 7122 can increase the bonding force between the main body portion 712 and the lens holder 300. Specifically, a portion of the lens holder 300 can be inserted into the groove 7122 of the main body portion 712, or a portion of the lens holder 300 can be integrated by double injection molding, thereby increasing the bonding force between the main body portion 712 and the lens holder 300.

[0074] A first protrusion 714 may be formed on one end of the main body portion 712. For example, the first protrusion 714 may be formed at the upper end of the main body portion 712. The first protrusion 714 may be formed to extend to one side. For example, the first protrusion 714 may extend in a direction opposite to the driving magnet 510 or the driving coil 520. In one or more examples, the first protrusion 714 may be formed as a single first protrusion 714 or multiple first protrusions 714. The first protrusions 714 may be formed with a predetermined distance between them. For example, two first protrusions 714 may be formed with a predetermined distance between them along the length of the main body portion 712. Meanwhile, in Figure 3 In the middle, two first protrusions 714 can be formed on the main body 712, but if necessary, the number of first protrusions 714 can be increased to three or more.

[0075] The first protrusion 714 can be configured to reduce separation between the drive magnet 510 and the lens barrel support 300. For example, the first protrusion 714 can be in close contact with the rear and upper surfaces of the drive magnet 510 together with the main body portion 712, and can reduce separation between the drive magnet 510 and the lens barrel support 300. The first protrusion 714 can be configured to align with the position of the drive magnet 510. For example, the first protrusion 714 can be configured to contact one side (e.g., the upper surface) of the drive magnet 510, and can be aligned with the position of the drive magnet 510 in the optical axis direction.

[0076] The second protrusion 716 may be formed on one end of the main body portion 712. For example, the second protrusion 716 may be formed at the lower end of the main body portion 712. The second protrusion 716 may be formed to extend to one side. For example, the second protrusion 716 may be formed to be oriented or extend in a direction opposite to the extending direction of the first protrusion 714. In the example, the second protrusion 716 may be formed continuously in the length direction of the main body portion 712. However, the number of second protrusions 716 formed on the main body portion 712 is not limited to such a number. Figure 3 As shown in the example. For example, if needed, two or more second protrusions 716 may be formed along the length of the main body portion 712 at a certain distance from each other.

[0077] The second protrusion 716 can extend to a predetermined size. For example, the extension length D2 of the second protrusion 716 can be less than the extension length D1 of the first protrusion 714. However, the extension length D2 of the second protrusion 716 does not necessarily have to be less than the extension length D1 of the first protrusion 714. For example, the extension length D2 of the second protrusion 716 can be increased or decreased within the range where double injection between the reinforcing member 710 and the lens holder 300 is possible.

[0078] The second protrusion 716 can improve the rigidity of the lens barrel support 300. For example, the second protrusion 716 can extend in a direction intersecting with the main body portion 712 and can prevent warping of the main body portion 712 and deformation of the lens barrel support 300 due to external impact.

[0079] If necessary, the reinforcing member 710 according to the exemplary embodiment can be modified. (Refer to...) Figure 4 and Figure 5 Describe the modified form of the reinforcing member 710.

[0080] First, refer to Figure 4 Describe the reinforcing member based on the first modified example.

[0081] The reinforcing member 710a, according to the modified example, can be configured to... Figure 2 The reinforcing members 710 shown have substantially similar shapes. For example, reinforcing member 710a may include a main body portion 712, one or more first protrusions 714 and second protrusions 716. However, the components of reinforcing member 710a according to the modified example are not limited to the main body portion 712, the first protrusions 714 and the second protrusions 716.

[0082] The reinforcing member 710a according to the modified example can differ from the reinforcing member 710 described above in terms of the shape of the main body portion 712. For example, the main body portion 712 of the reinforcing member 710a according to the modified example can be configured to improve the bonding force with the driving magnet 510. As a specific example, one or more holes 7124 can be formed in accordance with the following... Figure 4 In the main body portion 712 of the reinforcing member 710a shown in the modified example, the hole 7124 in the main body portion 712 can improve the bonding force between the reinforcing member 710a and the driving magnet 510. For example, the hole 7124 in the main body portion 712 can provide space in which the adhesive member 730 can be applied, thereby improving the bonding force between the reinforcing member 710a and the driving magnet 510. As another example, the hole 7124 in the main body portion 712 can provide space in which the lens barrel support 300 can directly contact the driving magnet 510, making it possible to perform double injection molding of the lens barrel support 300 and the driving magnet 510. The latter form can increase the connection force between the lens barrel support 300 and the reinforcing member 710a and the driving magnet 510.

[0083] In the following description, reference will be made to Figure 5 Describe the reinforcing member according to the second modified example.

[0084] The reinforcing member 710b, according to the modified example, can be configured to... Figure 3The reinforcing members 710 shown have substantially similar shapes. For example, reinforcing member 710b may include a main body portion 712, one or more first protrusions 714 and second protrusions 716. However, the components of reinforcing member 710b according to the modified example are not limited to the main body portion 712, the first protrusions 714 and the second protrusions 716.

[0085] According to the modified example, the reinforcing member 710b can be similar in shape to the second protrusion 716. Figure 3 The aforementioned reinforcing member 710 and Figure 4 The reinforcing member 710a shown is distinguished. For example, as Figure 5 As shown, the second protrusion 716 of the reinforcing member 710b according to the modified example can be formed to be longer in a direction away from the center of the main body portion 712 (e.g., the bisecting line TC of the main body portion 712). As a specific example, the length D21 of the second protrusion 7162 formed at the center of the main body portion 712 can be less than the length D22 of the adjacent second protrusion 7164, and the length D22 of the second protrusion 7164 can be less than the length D23 of the second protrusion 7166 formed at the outermost portion. The second protrusion 716 formed as described above can effectively reduce the moment of inertia acting on the reinforcing member 710b and the lens barrel support 300.

[0086] The camera module 10 according to one or more embodiments may further include reinforcing members other than those described above. For example, the camera module 10 may also include a second reinforcing member with a different shape and a [missing information - likely a specific type of reinforcing member]. Figure 2 The first reinforcing member 710 is shown in the shape shown. Reference will be made below. Figure 6 The shape of the second reinforcing member is described in more detail.

[0087] like Figure 6 As shown, the second reinforcing member 720 can be formed in a shape similar to the cross-sectional shape of the lens barrel support 300. For example, the cross-sectional shape of the second reinforcing member 720 can be almost annular. As another example, the second reinforcing member 720 can have an annular shape extending in the circumferential direction of the lens barrel support 300. However, the cross-sectional shape of the second reinforcing member 720 is not limited to an annular shape or a ring shape.

[0088] The second reinforcing member 720 can be formed in a way that does not affect the shape and form of the lens holder 300. For example, the inner diameter Ri of the second reinforcing member 720 can be larger than the radius Rh of the opening 302 formed in the lens holder 300. That is, the size of the opening 302 formed in the lens holder 300 can remain constant regardless of the presence or absence of the second reinforcing member 720. The second reinforcing member 720 may include a protrusion 724 projecting in the radial direction or the outer direction of the lens holder 300. The protrusion 724 can improve the stiffness of the second reinforcing member 720 and the stiffness of the lens holder 300.

[0089] The second reinforcing member 720 can be formed of a material having predetermined elasticity and stiffness. For example, the second reinforcing member 720 can be formed of a metallic material. However, the material of the second reinforcing member 720 is not limited to metal. The second reinforcing member 720 can be integrated with the lens barrel support 300. For example, the second reinforcing member 720 can be integrated with the lens barrel support 300 by injection molding or double injection molding.

[0090] The second reinforcing member 720 can be configured to increase the rigidity of the lens barrel support 300. For example, the second reinforcing member 720 can be integrated with the lens barrel support 300 and can maintain the opening 302 of the lens barrel support 300 to have a constant size and shape, and can reduce damage and deformation of the lens barrel support 300 due to external impact.

[0091] In the following text, reference will be made to Figure 7 Describe the modified form of the lens barrel support.

[0092] The camera module 10 according to the exemplary embodiment may include a lens holder 300a having a form different from the lens holder 300 of the example described above. However, the shapes of the lens holders 300 and 300a included in the camera module 10 according to the exemplary embodiment are not limited to... Figure 1 and Figure 7 The shape shown.

[0093] The lens barrel support 300a according to the modified example may include Figures 3 to 5 The first reinforcing members 710, 710a and 710b shown are as follows: Figure 6 The second reinforcing member 720 is shown. For example, the lens barrel support 300a according to the modified example may include... Figure 3 The first reinforcing member 710 shown and Figure 6 The second reinforcing member 720 is shown. As another example, the lens barrel support 300a according to the modified example may include... Figure 4 The first reinforcing member 710a shown and Figure 6The second reinforcing member 720 is shown. As another example, the lens barrel support 300a according to the modified example may include... Figure 5 The first reinforcing member 710b shown and Figure 6 The second reinforcing member 720 is shown. However, the modifications to the lens barrel support 300a are not limited to the above combinations.

[0094] like Figure 7 As shown, the lens barrel support 300a according to the modified example may include a first reinforcing member 710, 710a or 710b and a second reinforcing member 720 stacked in the vertical direction. The first reinforcing member 710, 710a or 710b and the second reinforcing member 720 may be integrated into the lens barrel support 300a. For example, the first reinforcing member 710, 710a or 710b and the second reinforcing member 720 may be integrated with the lens barrel support 300a by insertion injection or double injection.

[0095] In the example, Figure 7 The illustrated lens barrel support 300a may include a first reinforcing member 710, 710a, or 710b and a second reinforcing member 720, but the number of the first reinforcing members 710, 710a, or 710b and the second reinforcing member 720 included in the lens barrel support 300a is not limited to one. For example, the lens barrel support 300a may include two first reinforcing members 710, 710a, or 710b and one second reinforcing member 720, or one first reinforcing member 710, 710a, or 710b and two second reinforcing members 720. Furthermore, in the lens barrel support 300a according to the previous example, the two first reinforcing members 710, 710a, or 710b may be symmetrically arranged about the optical axis C, and in the lens barrel support 300a according to the later example, the two second reinforcing members 720 may be vertically symmetrically arranged about the driving magnet 510.

[0096] The first reinforcing member 710, 710a, or 710b and the second reinforcing member 720 may be connected or coupled to each other to improve the rigidity of the lens barrel support 300a. For example, the first reinforcing member 710, 710a, or 710b and the second reinforcing member 720 may be integrated by processes such as, but not limited to, welding and bonding. As another example, the first reinforcing member 710, 710a, or 710b and the second reinforcing member 720 may be securely connected by insertion. However, the first reinforcing member 710, 710a, or 710b and the second reinforcing member 720 need not be physically connected or coupled to each other. For example, the first reinforcing member 710, 710a, or 710b and the second reinforcing member 720 may be disposed in the lens barrel support 300a with a predetermined distance between them.

[0097] Since the lens barrel support 300a configured as described above may have a structure in which multiple reinforcing members 710, 710a or 710b and 720 support the lens barrel support 300a in the shape and form, the breakage or deformation of the lens barrel support 300a due to external impact and drop impact can be significantly reduced.

[0098] In the following description, reference will be made to Figure 8 Describe the connection configuration of camera module 10.

[0099] Camera module 10 can be configured in such a way that the aforementioned components are as follows: Figure 8 The components shown are combined into one unit. Additionally, as... Figure 8 As shown, the camera module 10 can be configured to have a relatively small height. Therefore, the camera module 10 according to the exemplary embodiment can be easily installed in a thin, small terminal such as a smartphone.

[0100] The camera module 10 according to the exemplary embodiment can reduce the separation of the drive magnet 510 and the breakage of the lens barrel support 300 due to rapid movement and vibration of the lens barrel support 300 and the lens barrel 400. Specifically, in the camera module 10 according to the exemplary embodiment, since the drive magnet 510 is firmly fixed to the lens barrel support 300 by the first reinforcing member 710, the separation of the drive magnet 510 due to external impact and drop impact can be significantly reduced. Furthermore, since the camera module 10 according to the exemplary embodiment has a structure in which one or more reinforcing members 710, 710a or 710b and 720 can improve the stiffness of the lens barrel support 300, the breakage of the lens barrel support 300 can be significantly reduced.

[0101] In the following description, reference will be made to Figures 9 to 16 A camera module according to another exemplary embodiment is described.

[0102] According to an exemplary embodiment, the camera module 12 may include a housing 100, a first movable frame 210, a second movable frame 220, a lens barrel support 300, a lens barrel 400, a first drive device 500, and a second drive device 600. However, the components of the camera module 12 are not limited to the above-described components. For example, the camera module 12 may also include ball supports 810, 820, and 830, a shield 900, and a fixing clip 910.

[0103] The housing 100 can be configured to accommodate a first movable frame 210, a second movable frame 220, a lens barrel support 300, and a lens barrel 400. The housing 100 can accommodate the first movable frame 210 to enable its movement. A ball support 810 can be disposed between the housing 100 and the first movable frame 210. More specifically, the ball support 810 can be disposed between a guide groove 108 of the housing 100 and a recess 218 of the first movable frame 210, allowing smooth movement of the first movable frame 210 in the optical axis C direction. Openings 104 and 105 can be formed in at least three side surfaces of the housing 100. A first drive device 500 and a second drive device 600 can be disposed in openings 104 and 105, respectively. Specifically, the driving magnet 510 and driving coil 520 of the first driving device 500 can be arranged to face each other in the first opening 104, and the driving magnets 612 and 614 and driving coils 622 and 624 of the second driving device 600 can be arranged to face each other in the two second openings 105.

[0104] The first movable frame 210 can be configured to support the second movable frame 220. The first movable frame 210 can support the second movable frame 220, allowing the second movable frame 220 to move. For example, the first movable frame 210 can support the second movable frame 220, allowing the second movable frame 220 to move in a direction intersecting the optical axis C. Friction between the first movable frame 210 and the second movable frame 220 can be reduced by a ball bearing 820. The ball bearing 820 can be disposed between a groove 214 in the first movable frame 210 and a groove 224 in the second movable frame 220. Grooves 214 and 224 can be formed to restrict the direction of movement of the second movable frame 220. For example, grooves 214 and 224 can be formed to extend in a second direction intersecting the optical axis C, such that the direction of movement of the second movable frame 220 can be restricted to a second direction intersecting the optical axis C.

[0105] The first driving device 500 can be disposed on the first movable frame 210. Specifically, the first driving magnet 510 of the first driving device 500 can be disposed on the first side surface of the first movable frame 210. In addition, a ball support member 810 can be disposed on the first side surface of the first movable frame 210. More specifically, the ball support member 810 can be disposed in a groove 218 on the first side surface. The first movable frame 210 can be formed into an open shape with at least two side surfaces open in the direction intersecting the optical axis C. For example, two adjacent side surfaces of the first movable frame 210 can be partially open, so that the second driving magnets 612 and 614 mounted on the lens barrel support 300 can be opposite to the second driving coils 622 and 624.

[0106] The first movable frame 210 can be configured to be driven in a direction different from the driving direction of the lens holder 300 and the second movable frame 220. For example, the first movable frame 210 can be driven in the optical axis C direction by the operation of the first driving device 500. The first movable frame 210 can be configured to accommodate the lens holder 300 and the second movable frame 220. For example, the second movable frame 220 and the lens holder 300 can be sequentially arranged in the optical axis C direction within the internal space of the first movable frame 210. Therefore, when the first movable frame 210 moves in the optical axis C direction, the second movable frame 220 and the lens holder 300 can also move together in the optical axis C direction. Since the lens holder 300 and the second movable frame 220 are movable only within the internal space of the first movable frame 210, the movement of the lens holder 300 and the second movable frame 220 does not affect the driving of the first movable frame 210.

[0107] The second movable frame 220 can support the lens barrel support 300, enabling movement of the lens barrel support 300. For example, the second movable frame 220 can support the lens barrel support 300 so that the lens barrel support 300 can move in a first direction intersecting the optical axis C. A ball support member 830, facilitating easy movement of the lens barrel support 300, can be disposed between the second movable frame 220 and the lens barrel support 300. More specifically, the ball support member 830 can be disposed between a groove 306 in the lens barrel support 300 and a groove 226 in the second movable frame 220. Grooves 226 and 306 can restrict the direction of movement of the lens barrel support 300. For example, grooves 226 and 306 can extend in the first direction intersecting the optical axis C, and can restrict the direction of movement of the lens barrel support 300 to the first direction intersecting the optical axis C.

[0108] The first movable frame 210 and the second movable frame 220 can be configured to support the lens barrel support 300. For example, the second movable frame 220 can be configured to support the lens barrel support 300, and the first movable frame 210 can be configured to support the lens barrel support 300 via the second movable frame 220.

[0109] The lens barrel support 300 can be configured to be coupled to the lens barrel 400. For example, the lens barrel support 300 may include an opening 302 that allows the lens barrel 400 to be inserted into the center of the lens barrel support 300. The opening 302 may be open in the direction of the optical axis C. The center of the opening 302 may coincide with the optical axis C of the lens barrel 400. The lens barrel support 300 can be configured to accommodate a portion of the second drive device 600. For example, the lens barrel support 300 may include mounting grooves 304 on its two side surfaces, respectively, in which second drive magnets 612 and 614 of the second drive device 600 are disposed.

[0110] The lens barrel 400 can be formed in the shape of a truncated cone. However, the shape of the lens barrel 400 is not limited to a truncated cone. For example, the lens barrel 400 can have a cylindrical shape or other shapes. The lens barrel 400 can be configured to house lenses. For example, one or more lenses stacked sequentially along the optical axis C can be disposed in the lens barrel 400.

[0111] The first driving device 500 may include a first driving magnet 510 and a first driving coil 520. The first driving magnet 510 may be disposed in the first movable frame 210, and the first driving coil 520 may be disposed in the first opening 104 of the housing 100. The first driving magnet 510 and the first driving coil 520 can provide the driving force required to move the first movable frame 210 in the optical axis C direction. Specifically, the first movable frame 210 can move in the optical axis C direction based on the first driving magnet 510 and the first driving coil 520. The first movable frame 210 can move together with the lens barrel 400 housed therein. Therefore, focus adjustment of the camera module 12 can be naturally performed according to the movement of the first movable frame 210 in the optical axis C direction.

[0112] The second driving device 600 may include second driving magnets 612 and 614 and second driving coils 622 and 624. The second driving magnets 612 and 614 may be disposed within the lens barrel support 300, and the second driving coils 622 and 624 may be disposed within the second opening 105 of the housing 100. The second driving magnets 612 and 614 and the second driving coils 622 and 624 can provide the driving force required for the lens barrel support 300 to move in a direction intersecting the optical axis C. Specifically, the second driving magnet 612 and the second driving coil 622 can drive the lens barrel support 300 in a first direction intersecting the optical axis C, and the second driving magnet 614 and the second driving coil 624 can drive the second movable frame 220 and the lens barrel support 300 in a second direction intersecting the optical axis C. Therefore, optical image stabilization of the camera module 12 can be naturally performed by the movement of the lens barrel support 300 driven by the second driving device 600.

[0113] The flexible substrate 630 can be configured to support the first drive coil 520 and the second drive coils 622 and 624. For example, the flexible substrate 630 can fix the first drive coil 520 and the second drive coils 622 and 624 to the outside of the housing 100, such that the first drive coil 520 and the second drive coils 622 and 624 can be opposite to the first drive magnet 510 and the second drive magnets 612 and 614. The flexible substrate 630 can be configured to provide current and control signals to the first drive coil 520 and the second drive coils 622 and 624. For example, the flexible substrate 630 can be connected to an external power supply and an external control device, and can supply current and control signals to the first drive coil 520 and the second drive coils 622 and 624.

[0114] The retaining clip 910 can be configured to prevent the lens barrel support 300 and the second movable frame 220 from separating from the first movable frame 210. For example, the retaining clip 910 can be attached to the first movable frame 210 while the upper part of the lens barrel support 300 is pressed down, thereby preventing the lens barrel support 300 and the second movable frame 220 from separating from the first movable frame 210.

[0115] The shield 900 can be configured to shield the upper portion and portions of the four side surfaces of the housing 100. The shield 900 can be configured to prevent malfunction of the camera module 12 due to harmful electromagnetic waves. For example, the shield 900 can be formed of a metallic material to block magnetic field interference between the first drive device 500 and the second drive device 600 caused by harmful electromagnetic waves.

[0116] A camera module 12 according to one or more embodiments can be configured to reduce deformation of the first movable frame 210 due to external impacts and drop impacts. For example, a camera module 12 according to an exemplary embodiment may also include components to increase the stiffness of the first movable frame 210. Hereinafter, reference will be made to… Figure 10 and Figure 11 The structure of the first movable frame 210 is described in more detail.

[0117] Due to the first driving magnet 510, as Figure 10 As shown, the first drive magnet 510 is disposed on one side of the first movable frame 210, so the weight of the portion on which the first drive magnet 510 is disposed can be heavier than that of the other portions. Therefore, when an external impact is applied to the first movable frame 210, the portion on which the first drive magnet 510 is disposed may deform, or the portion on which the first drive magnet 510 is disposed may be easily damaged.

[0118] Considering the above issues, such as Figure 11As shown, the camera module 12 according to the exemplary embodiment may also include a first reinforcing member 710c disposed in the first movable frame 210.

[0119] In the example, the first reinforcing member 710c may be formed on one side of the first movable frame 210. For example, the first reinforcing member 710c may be formed on the side of the first movable frame 210 on which the first driving magnet 510 is disposed. The first reinforcing member 710c may be integrated with the first movable frame 210. For example, the first reinforcing member 710c may be integrated with the first movable frame 210 by, for example, insertion injection or double injection. The first reinforcing member 710c may be configured to increase the stiffness of the first movable frame 210. For example, the first reinforcing member 710c may be formed of a material with high strength and stiffness, and may increase the stiffness of weak parts of the first movable frame 210. The first reinforcing member 710c may be configured to support the first driving magnet 510. For example, as Figure 11 As shown, the first reinforcing member 710c can be configured to support one surface of the first driving magnet 510.

[0120] In the following text, reference will be made to Figure 12 The structure of the first reinforcing member 710c is described in more detail.

[0121] The first reinforcing member 710c can be formed of a material having predetermined elasticity and stiffness. For example, the first reinforcing member 710c can be formed of a metallic material. However, the material of the first reinforcing member 710c is not limited to metallic. The first reinforcing member 710c may include a first body portion 712, one or more first outward protrusions 714, and first inward protrusions 716. However, the components of the first reinforcing member 710c are not limited to the first body portion 712, the first outward protrusions 714, and the first inward protrusions 716. The first body portion 712, the first outward protrusions 714, and the first inward protrusions 716 of the first reinforcing member 710c can be integrated together with each other through a series of processes. For example, the first reinforcing member 710c can be rapidly formed by a stamping process in a single process. However, the method of forming the first reinforcing member 710c is not limited to a stamping process.

[0122] The first main body portion 712 can be configured to increase the torsional stiffness of the first movable frame 210. For example, the first main body portion 712 can extend in a plane direction parallel to the optical axis C, and can prevent or reduce torsional deformation of the first movable frame 210. The first main body portion 712 can be formed to a considerably long length. For example, the length TD of the first main body portion 712 can be greater than or equal to the length ML of the first driving magnet 510. However, the length TD of the first main body portion 712 is not limited to the above-described dimensional relationships. The first main body portion 712 can have a predetermined height Th. For example, the height Th of the first main body portion 712 can be greater than or equal to the height Mh of the first driving magnet 510. However, the height Th of the first main body portion 712 is not limited to the above-described dimensional relationships.

[0123] A groove 7122 can be formed in the first main body portion 712. The groove 7122 can increase the bonding force between the first main body portion 712 and the first movable frame 210. Specifically, a portion of the first movable frame 210 can be inserted into the groove 7122 of the first main body portion 712, or a portion of the first movable frame 210 can be integrated by injection molding, thereby increasing the bonding force between the first main body portion 712 and the first movable frame 210.

[0124] A first outward protrusion 714 may be formed on one end of the first main body portion 712. For example, the first outward protrusion 714 may be formed at the upper end of the first main body portion 712. The first outward protrusion 714 may extend to one side. For example, the first outward protrusion 714 may extend in the direction opposite to the first driving magnet 510 or the first driving coil 520. The first outward protrusions 714 may be formed with a predetermined distance between them. For example, two first outward protrusions 714 may be formed with a predetermined distance between them along the length of the first main body portion 712. While two first outward protrusions 714 may be formed on the first main body portion 712 in the accompanying drawings, the number of first outward protrusions 714 may be increased to three or more if necessary.

[0125] The first outward protrusion 714 can be configured to reduce separation between the first driving magnet 510 and the first movable frame 210. For example, the first outward protrusion 714 can be in close contact with the rear and upper surfaces of the first driving magnet 510 together with the first body portion 712, thereby reducing separation between the first driving magnet 510 and the first movable frame 210. The first outward protrusion 714 can be configured to align with the position of the first driving magnet 510. For example, the first outward protrusion 714 can be configured to contact a side surface (e.g., the upper surface) of the first driving magnet 510 and can be aligned with the position of the first driving magnet 510 in the optical axis direction.

[0126] A first inward protrusion 716 may be formed on one end of the first main body portion 712. For example, the first inward protrusion 716 may be formed at the lower end of the first main body portion 712. The first inward protrusion 716 may extend to one side. For example, the first inward protrusion 716 may extend in a direction opposite to the extending direction of the first outward protrusion 714. In the example, the first inward protrusion 716 may be continuously formed along the length of the first main body portion 712. However, the number of first inward protrusions 716 formed on the first main body portion 712 is not limited. Figure 12 As shown in the example. For example, if needed, two or more first inward protrusions 716 may be formed along the length of the first body portion 712 at a certain distance from each other.

[0127] The first inward protrusion 716 can extend to a predetermined size or length. For example, the extension length D2 of the first inward protrusion 716 can be less than the extension length D1 of the first outward protrusion 714. However, the extension length D2 of the first inward protrusion 716 does not necessarily have to be less than the extension length D1 of the first outward protrusion 714. For example, the extension length D2 of the first inward protrusion 716 can be increased or decreased within a range that allows for double injection between the first reinforcing member 710c and the first movable frame 210.

[0128] The first inward protrusion 716 can increase the rigidity of the first movable frame 210. For example, the first inward protrusion 716 can extend in a direction intersecting with the first main body portion 712 and can prevent warping of the first main body portion 712 and deformation of the first movable frame 210 due to external impact.

[0129] Camera module 12 according to one or more embodiments can be configured to reduce deformation of lens barrel support 300 due to external impacts and drop impacts. For example, camera module 12 according to an exemplary embodiment may also include components to increase the stiffness of lens barrel support 300. (See reference...) Figures 13 to 15 The structure of the lens barrel support 300 is described in more detail.

[0130] like Figure 13 As shown, since the second drive magnets 612 and 614, which have a relatively large weight, can be disposed on two adjacent side surfaces of the lens barrel support 300, external impacts or forces may be concentrated on the portions where the second drive magnets 612 and 614 are disposed. Furthermore, external impacts and forces concentrated on the portions where the second drive magnets 612 and 614 are disposed may cause rapid breakage or deformation of the lens barrel support 300.

[0131] The camera module 12 according to one or more embodiments can also be as follows: Figure 14The diagram includes a second reinforcing member 710d disposed in the lens barrel support 300 to solve the above-mentioned problem.

[0132] The second reinforcing member 710d can be formed on at least two side surfaces of the lens barrel support 300. For example, the second reinforcing member 710d can be formed on a first side surface and a second side surface of the lens barrel support 300 on which the second driving magnets 612 and 614 are disposed. The second reinforcing member 710d can be integrated with the lens barrel support 300. For example, the second reinforcing member 710d can be integrated with the lens barrel support 300 by, for example, insertion injection or double injection. The second reinforcing member 710d can be configured to increase the stiffness of the lens barrel support 300. For example, the second reinforcing member 710d can be formed of a material with high strength and stiffness, so that the stiffness of the weak parts of the lens barrel support 300 can be increased. The second reinforcing member 710d can be configured to support the second driving magnets 612 and 614. For example, as Figure 14 As shown, the second reinforcing member 710d can be configured to support a surface of the second drive magnets 612 and 614.

[0133] In the following text, reference will be made to Figure 15 The structure of the second reinforcing member 710d is described in more detail.

[0134] The second reinforcing member 710d can be formed of a material having predetermined elasticity and stiffness. For example, the second reinforcing member 710d can be formed of a metallic material. However, the material of the second reinforcing member 710d is not limited to a metallic material. The second reinforcing member 710d may include a second main body portion 712, a second outward protrusion 714, and a second inward protrusion 716. However, the components of the second reinforcing member 710d are not limited to the second main body portion 712, the second outward protrusion 714, and the second inward protrusion 716. The second main body portion 712, the second outward protrusion 714, and the second inward protrusion 716 of the second reinforcing member 710d can be integrated through a series of processes. For example, the second reinforcing member 710d can be rapidly formed by a stamping process in a single process. However, the method of forming the second reinforcing member 710d is not limited to a stamping process.

[0135] The second main body portion 712 can be configured to improve the torsional stiffness of the lens barrel support 300. For example, the second main body portion 712 can extend in a plane direction parallel to the optical axis C, and can prevent or reduce torsional deformation of the lens barrel support 300. The second main body portion 712 can be formed to a considerably long length. For example, the length TD of the second main body portion 712 can be greater than or equal to the length ML of the second drive magnets 612 and 614. However, the length TD of the second main body portion 712 is not limited to the above-described dimensional relationships. The second main body portion 712 can have a predetermined height Th. For example, the height Th of the second main body portion 712 can be greater than or equal to the height Mh of the second drive magnets 612 and 614. However, the height Th of the second main body portion 712 is not limited to the above-described dimensional relationships.

[0136] One or more holes 7124 may be formed in the second body portion 712. The holes 7124 may increase the bonding force between the lens holder 300 and the second drive magnets 612 and 614. Specifically, adhesive members 730 that increase the bonding force between the lens holder 300 and the second drive magnets 612 and 614 may be injected or coated into the holes 7124 of the second body portion 712.

[0137] The second outward protrusion 714 may be formed on one end of the second main body portion 712. For example, the second outward protrusion 714 may be formed at the upper end of the second main body portion 712. The second outward protrusion 714 may be formed to extend to one side. For example, the second outward protrusion 714 may extend in a direction opposite to that of the second driving magnets 612 and 614 or the second driving coils 622 and 624. The second outward protrusions 714 may be formed to be spaced apart from each other. For example, two second outward protrusions 714 may be formed with a predetermined distance between them along the length of the second main body portion 712. Meanwhile, in Figure 15 In the middle, two second outward protrusions 714 can be formed on the second main body 712, but if needed, the number of second outward protrusions 714 can be increased to three or more.

[0138] The second outward protrusion 714 can be configured to reduce the separation of the second drive magnets 612 and 614 from the lens holder 300. For example, the second outward protrusion 714 can be in close contact with the rear and upper surfaces of the second drive magnets 612 and 614 together with the second body portion 712, thereby preventing the second drive magnets 612 and 614 from separating from the lens holder 300. The second outward protrusion 714 can be configured to align with the position of the second drive magnets 612 and 614. For example, the second outward protrusion 714 can be configured to contact a side surface (e.g., the upper surface) of the second drive magnets 612 and 614, and can be aligned with the position of the second drive magnets 612 and 614 in the optical axis direction.

[0139] The second inward protrusion 716 may be formed on one end of the second main body portion 712. For example, the second inward protrusion 716 may be formed at the lower end of the second main body portion 712. The second inward protrusion 716 may be formed to extend to one side. For example, the second inward protrusion 716 may extend in a direction opposite to the extending direction of the second outward protrusion 714. The second inward protrusion 716 may be continuously formed along the length of the second main body portion 712. However, the number of second inward protrusions 716 formed on the second main body portion 712 is not limited to... Figure 15 As shown in the example. For example, if needed, two or more second inward protrusions 716 may be formed along the length of the second body portion 712 at a certain distance from each other.

[0140] The second inward protrusion 716 can extend to a predetermined size or length. For example, the extension length D2 of the second inward protrusion 716 can be less than the extension length D1 of the second outward protrusion 714. However, the extension length D2 of the second inward protrusion 716 does not necessarily have to be less than the extension length D1 of the second outward protrusion 714. For example, the extension length D2 of the second inward protrusion 716 can be increased or decreased within a range where double injection can be performed between the second reinforcing member 710d and the lens holder 300.

[0141] The second inward protrusion 716 can improve the rigidity of the lens barrel support 300. For example, the second inward protrusion 716 can extend in a direction intersecting with the second main body portion 712, and can prevent warping of the second main body portion 712 and deformation of the lens barrel support 300 due to external impact.

[0142] In the camera module 12 configured as described above, the components (first movable frame 210 and lens barrel support 300) that move in the direction of the optical axis C and in the direction intersecting the optical axis C can have high rigidity through reinforcing members 710c and 710d formed of different materials, which can significantly reduce the breakage or deformation of the movable components due to external impact or drop impact. Therefore, according to the exemplary embodiment, the durability and driving reliability of the camera module 12 can be improved.

[0143] According to the above exemplary embodiments, a camera module that can improve the driving reliability of focus adjustment function or image stabilization function can be provided.

[0144] In addition, camera modules that can withstand external impacts and drop impacts can be provided.
