[0092] Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings.

[0093] In the following description of the embodiments, it will be understood that when each element is mentioned as being "on" or "under" another element, the element may be located "directly" on or under the other element, or may be formed "indirectly" with intermediate elements also present. Additionally, when an element is referred to as "on" or "under," "under" and "on" may be included based on that element.

[0094] Furthermore, relational terms such as "first," "second," "above / upper part / above," and "below / lower part / below" are used only to distinguish one object or element from another, and do not necessarily require or involve any physical or logical relationship or order between these objects or elements. Additionally, the same reference numerals will be used as much as possible in all figures to refer to the same or similar parts.

[0095] Furthermore, the terms "comprising," "including," and "having" mean that an element may be inherent, unless otherwise stated. Therefore, the terms should be interpreted as not excluding other elements, but rather including those other elements. Additionally, the term "corresponding" can mean at least one of "relative" or "overlapping."

[0096] For ease of description, the lens moving device according to the embodiment will be described using a Cartesian coordinate system (x, y, z). However, other different coordinate systems may be used, and this disclosure is not limited thereto. In the figures, the x-axis and y-axis directions are directions perpendicular to the z-axis direction, which is the optical axis direction. The z-axis direction, which is the optical axis direction, may be referred to as the "first direction," the x-axis direction as the "second direction," and the y-axis direction as the "third direction." Furthermore, the optical axis direction may be defined as the optical axis direction of the lens connected to the lens moving device.

[0097] A "shake compensation function" for small camera modules in mobile devices, such as smartphones or tablets, can be the following: moving the lens in a direction perpendicular to the optical axis or tilting the lens relative to the optical axis to counteract vibrations (or movements) caused by the user's hand tremors. The term "shake compensation" is also used interchangeably with "optical image stabilization (OIS)".

[0098] Additionally, the "autofocus function" can be the following: to move the lens along the optical axis according to the distance from the object to automatically focus on the object, so as to acquire a clear image of the object on the image sensor.

[0099] The lens moving device according to the embodiment can perform an autofocus operation to move an optical module including at least one lens along a first direction.

[0100] Furthermore, in the following description, the term "terminal" may be referred to as a pad, electrode, conductive layer, or bonding portion. Additionally, in the following description, the term "through-hole" may be referred to as a "hole".

[0101] In the following text, "lens moving device" may be used in place of "voice coil motor", "lens moving motor" or "actuator".

[0102] Figure 1 This is a perspective view of the lens moving device 100 according to the embodiment. Figure 2 yes Figure 1 An exploded view of the lens moving device 100. Figure 3 This is a plan view of the lens moving device 100, in which the cover member 300 has been removed.

[0103] Reference Figures 1 to 3 The lens moving device 100 may include a winding frame 110, a first coil 120, a housing 140, a first magnet 130-1, a second magnet 130-2, a third magnet 130-3, an upper elastic member 150, a lower elastic member 160, and a second coil 230.

[0104] The lens moving device 100 may also include a dummy component 135.

[0105] The lens moving device 100 may also include at least one of a base 210, a support member 220, and a circuit board 250.

[0106] Additionally, the lens moving device 100 may also include a circuit board 190 and a first position sensor 170 configured to perform AF feedback drive.

[0107] Furthermore, the lens moving device 100 may also include a sensing magnet 180 configured to sense the magnetic force of the first position sensor 170. Additionally, the lens moving device 100 may also include a balancing magnet 185 configured to reduce the effect of the magnetic field of the sensing magnet 180.

[0108] In addition, the lens moving device 100 may also include a second position sensor 240 (see Figure 9b The second position sensor 240 is configured to perform optical image stabilization (OIS) feedback drive. Additionally, the lens moving device 100 may also include a cover member 300.

[0109] The implementation can provide a lens moving device including an OIS function that can reduce or prevent magnetic field interference between magnets included in two adjacent lens moving units mounted in a dual-camera module.

[0110] In addition, the implementation can maintain a balance between the electromagnetic force generated in the X-axis direction perpendicular to the optical axis (OA) and the electromagnetic force generated in the Y-axis direction in order to perform the OIS function, thereby preventing the lens moving unit from tilting in the X-axis direction or the Y-axis direction.

[0111] In addition, the implementation method can reduce the number of OIS magnets and the size of the OIS magnets, thereby reducing the weight of the OIS moving unit and thus reducing current consumption.

[0112] First, the winding frame 110 will be described.

[0113] The winding frame 110 is disposed inside the housing 140, and the winding frame 110 can move along the optical axis (OA) or a first direction (e.g., the Z-axis direction) due to the electromagnetic interaction between the first coil 120 and the first magnet 130-1 and the second magnet 130-2.

[0114] Figure 4a It is a three-dimensional view showing the winding frame 110, the first coil unit 120-1, the second coil unit 120-2, and the sensing magnet 180. Figure 4b This is a three-dimensional view showing the connection of the winding frame 110, the first coil unit 120-1, the second coil unit 120-2, and the sensing magnet 180.

[0115] Reference Figure 4a and Figure 4b The winding frame 110 may have an opening in which a lens or lens barrel is mounted. For example, the opening of the winding frame 110 may be a through hole formed through the winding frame 110, and the shape of the opening of the winding frame 110 may be circular, elliptical, or polygonal. However, this disclosure is not limited thereto.

[0116] The lens can be directly mounted in the opening of the winding frame 110. However, this disclosure is not limited thereto. In another embodiment, a lens barrel to which at least one lens is mounted or coupled can be coupled to or mounted in the opening of the winding frame 110. The lens or lens barrel can be coupled to the inner circumferential surface 110a of the winding frame 110 in various ways.

[0117] The winding frame 110 may include first side portions (or first sides) spaced apart from each other and second side portions (or second sides) spaced apart from each other. Each second side portion may connect two adjacent first side portions to each other. For example, the first side portions of the winding frame 110 may be referred to as "side portions", and the second side portions of the winding frame 110 may be referred to as "corner portions or corners".

[0118] The first mounting recess 41, in which the first coil unit 120-1 is mounted, seated, or arranged, can be provided in one side portion (e.g., the first side portion) of the side portion of the winding frame 110. The second mounting recess 42, in which the second coil unit 120-2 is mounted, seated, or arranged, can be provided in another side portion (e.g., the second side portion) of the side portion of the winding frame 110.

[0119] For example, the first seated recess 41 and the second seated recess 42 can be provided in two opposite side portions of the side portion of the winding frame 110. The first seated recess 41 and the second seated recess 42 can be recessed from the outer surface of the two side portions of the winding frame 110 and can have a shape that conforms to the shape of the first coil unit 120-1 and the second coil unit 120-2.

[0120] In another embodiment, a first protrusion on which a first coil unit 120-1 is mounted or wound may be provided on one side portion of the winding frame 110, and a second protrusion on which a second coil unit 120-2 is mounted or wound may be provided on another side portion of the side portion of the winding frame 110.

[0121] The winding frame 110 may include a first recess 180a disposed in another side portion (e.g., a fourth side portion) of the side portion of the winding frame 110, such that the sensing magnet 180 is mounted or disposed in the first recess. For example, the fourth side portion of the winding frame 110 may be a side portion in which the first coil unit 120-1 or the second coil unit 120-2 is not disposed.

[0122] Furthermore, the winding frame 110 may include a second recess disposed in another side portion (e.g., a third side portion) of the side portion of the winding frame 110, such that the balancing magnet 185 is mounted or disposed in the second recess. For example, the third side portion of the winding frame 110 may be a side portion that does not have the first coil unit 120-1 or the second coil unit 120-2 disposed thereon and is opposite to the third side portion of the winding frame 110.

[0123] The winding frame 110 may include a protrusion 111 disposed on a corner portion of the winding frame 110. The protrusion 111 may protrude in a direction parallel to a line that extends through the center of the opening of the winding frame 110 and is perpendicular to the optical axis. However, this disclosure is not limited thereto.

[0124] The protrusion 111 of the winding frame 110 can correspond to the recess 145 of the housing 140. The protrusion 111 can be inserted into or arranged in the recess 145 of the housing 140 and can prevent or prevent the winding frame 110 from moving or rotating about the optical axis while deviating from a predetermined range.

[0125] An avoidance recess 122a may be provided in the upper surface of the corner portion of the winding frame 110, which is configured to avoid spatial interference with the first frame connection portion 153 of the upper elastic member 150.

[0126] Despite Figure 4a As not shown, the winding frame 110 may include a first stop protruding from the upper surface of the winding frame 110 and a second stop protruding from the lower surface of the winding frame 110. The first and second stops of the winding frame 110 can prevent the upper surface of the winding frame 110 from directly colliding with the interior of the upper plate of the cover member 30, and can prevent the lower surface of the winding frame 110 from directly colliding with the base 210, the second coil 230 and / or the circuit board 250, even if the winding frame 110 deviates from a predetermined range due to external impact while moving in the first direction to perform the autofocus function.

[0127] The winding frame 110 may have a first connecting portion on its upper surface, which is configured to be connected to and fixed to the upper elastic member 150, and the winding frame 110 may have a second connecting portion on its lower surface, which is configured to be connected to and fixed to the lower elastic member 160.

[0128] For example, in Figure 4a and Figure 4b In this embodiment, the first and second connecting portions of the winding frame 110 may be flat. However, this disclosure is not limited thereto. In another embodiment, each of the first and second connecting portions of the winding frame 110 may have a recessed or protruding shape.

[0129] Next, the first coil 120 will be described.

[0130] The first coil 120 includes a first coil unit 120-1 and a second coil unit 120-2 arranged in two opposite side portions of the side portion of the winding frame 110. Here, the coil unit may be referred to as a coil, a coil section, a coil block, or a coil loop.

[0131] For example, the first coil unit 120-1 may be arranged in the first seating recess 41 of the winding frame 110, and the second coil unit 120-2 may be arranged in the second seating recess 42 of the winding frame 110. However, this disclosure is not limited thereto. In another embodiment, each of the first coil unit 120-1 and the second coil unit 120-2 may be wound on at least one protrusion provided on the side portion of the winding frame 110, or may be mounted on at least one protrusion provided on the side portion of the winding frame 110.

[0132] Each of the first coil unit 120-1 and the second coil unit 120-2 may include at least one of an elliptical shape, an orbital shape, and a closed curve shape. For example, each of the first coil unit 120-1 and the second coil unit 120-2 may have the shape of a coil loop wound around an axis that extends through the center of the opening of the winding frame 110 and is perpendicular to the optical axis.

[0133] For example, each of the first coil unit 120-1 and the second coil unit 120-2 may have a first portion 3a, a second portion 3b arranged below the first portion 3a, and a third portion 3c configured to connect the first portion 3a and the second portion 3b to each other, and each of the first coil unit 120-1 and the second coil unit 120-2 may form a closed curve through the first portion 3a to the third portion 3c.

[0134] The third part 3c may include a first connecting part 3c1 and a second connecting part 3c2. The first connecting part 3c1 is configured to connect one end of the first part 3b1 to one end of the second part 3b, and the second connecting part 3c2 is configured to connect the other end of the first part 3b1 to the other end of the second part 3b.

[0135] For example, the first part 3a can be called the "first straight part", the second part 3b can be called the "second straight part", the third part 3c can be called the "bent part", the first connecting part 3c1 can be called the first bent part, and the second connecting part 3c2 can be called the second bent part.

[0136] The first coil 120 may include a connection portion (not shown), a connecting coil, or a connecting wire disposed between the first coil unit 120-1 and the second coil unit 120-2, so as to connect the first coil unit 120-1 and the second coil unit 120-2 to each other.

[0137] One end of the connecting portion of the first coil 120 can be connected to one end of the first coil unit 120-1, and the other end of the connecting portion of the first coil 120 can be connected to one end of the second coil unit 120-2. That is, the first coil unit 120-1 and the second coil unit 120-2 can be connected in series with each other through the connecting portion of the first coil 120.

[0138] The connection portion of the first coil 120 can be opposite to the third magnet 130-3, and can be arranged between the third magnet 130-3 and the winding frame 110.

[0139] Alternatively, in another embodiment, the connecting portion of the first coil 120 may be arranged between the fourth side portion of the winding frame 110 and the fourth side portion of the housing 140. For example, the connecting portion of the first coil 120 may be opposite to the dummy member 135 and may be disposed between the dummy member 135 and the winding frame 110.

[0140] In another embodiment, the first coil unit 120-1 and the second coil unit 120-2 may be separated from or spaced apart from each other.

[0141] When a drive signal (e.g., drive current) is applied to the first coil 120, an electromagnetic force is generated through the electromagnetic interaction between the first coil 120 and the first magnet 130-1 and the second magnet 130-3, and the winding frame 110 can move along the optical axis (OA) direction by the generated electromagnetic force.

[0142] At the initial position of the AF moving unit, the winding frame 110 can move in the vertical direction (e.g., the Z-axis direction), which is referred to as bidirectional drive of the AF moving unit. Alternatively, at the initial position of the AF moving unit, the winding frame 110 can move only in one of the upward and downward directions, which is referred to as unidirectional drive of the AF moving unit.

[0143] Reference Figure 10b At the initial position of the AF moving unit, the first coil unit 120-1 may be opposite to or overlap with the first magnet 130-1 in a direction perpendicular to the optical axis and in a direction from the optical axis to the first coil unit 120-1 (or the center of the first coil unit 120-1), but may not be opposite to or overlap with the third magnet 130-3.

[0144] At the initial position of the AF moving unit, the second coil unit 120-2 may be opposite to or overlap with the second magnet 130-2 in a direction perpendicular to the optical axis and in a direction from the optical axis to the second coil unit 120-2 (or the center of the second coil unit 120-2), but may not be opposite to or overlap with the third magnet 130-3.

[0145] The AF moving unit may include a winding frame 110 and components coupled to the winding frame 110. For example, the AF moving unit may include the winding frame 110, a first coil 120, a sensing magnet 180, and / or a balancing magnet. Additionally, the AF moving unit may also include a lens mounted in the winding frame 110.

[0146] The initial position of the AF moving unit can be its original position when no power is applied to the first coil 120, or the position of the AF moving unit caused by the elastic deformation of the upper elastic member 150 and the lower elastic member 160 solely due to the weight of the AF moving unit. Alternatively, the initial position of the AF moving unit (e.g., the winding frame 110) can be the position of the AF moving unit when gravity acts along the direction from the winding frame 110 to the base 210, or when gravity acts along the direction from the base 210 to the winding frame 110.

[0147] Next, the sensing magnet 180 will be described.

[0148] The sensing magnet 180 can be arranged in one of the side portions of the winding frame 110 where the first coil unit 120-1 and the second coil unit 120-2 are not arranged. For example, the sensing magnet 180 can be arranged in the first recess 180a of the winding frame 110.

[0149] When the lens moving device 100 includes a balancing magnet 185, the balancing magnet 185 can be arranged on another side portion of the side portion of the winding frame 110 where the first coil unit 120-1 and the second coil unit 120-2 are not arranged. For example, the balancing magnet 185 can be arranged in a second recess (not shown) of the winding frame 110.

[0150] The balancing magnet 185 can counteract the magnetic field effect of the sensing magnet 180 and can be balanced with the sensing magnet 180 in weight, thereby enabling precise AF operation.

[0151] The interface between the N and S poles of the sensing magnet 180 (and / or the balancing magnet 185) can be parallel to a direction perpendicular to the optical axis. However, this disclosure is not limited thereto. For example, in another embodiment, the interface between the N and S poles can be parallel to the optical axis.

[0152] For example, the sensing magnet 180 may be a unipolar magnetized magnet having a single N pole and a single S pole. However, this disclosure is not limited thereto. In another embodiment, the sensing magnet may be a bipolar magnetized magnet.

[0153] The sensing magnet 180 can move along the optical axis direction OA together with the winding frame 110 due to the interaction between the first coil unit 120-1 and the first magnet 130-1, and the interaction between the second coil unit and the second magnet 130-2. The first position sensor 170 can sense the strength of the magnetic field of the sensing magnet 180 moving along the optical axis direction, and can output an output signal based on the sensing result.

[0154] For example, the controller 830 of the camera module 200 or the controller 780 of the terminal 200A can detect the displacement of the winding frame 110 along the optical axis based on the output signal output from the first position sensor 170.

[0155] In another embodiment, the sensing magnet 180 and / or the balancing magnet 185 can be omitted, the first position sensor can be mounted to the winding frame instead of the housing, and the winding frame 2110 and the first position sensor move along the optical axis due to the interaction between the first coil 2120 and the first magnet 130, thereby the first position sensor can sense the strength of the magnetic field of the first magnet and can output an output signal based on the sensing result.

[0156] Next, the housing 140 will be described.

[0157] The housing 140 receives at least a portion of the winding frame 110 therein and supports the first magnet 130-1, the second magnet 130-2, the third magnet 130-3 and the dummy member 135.

[0158] For example, the OIS moving unit (or lens moving unit) may include an AF moving unit and a housing 140. For example, the OIS moving unit (or lens moving unit) may include components (e.g., 130-1 to 130-3, 135, 190, and 170) mounted to the housing 140.

[0159] For example, the OIS moving unit (or lens moving unit) can be moved by OIS driven by the electromagnetic force caused by the interaction between the first magnet 130-1 to the third magnet 130-3 and the second coil 230.

[0160] Figure 5a It is a perspective view of the housing 140, the first magnet 130-1, the second magnet 130-2, the third magnet 130-3, and the dummy component 135, and Figure 5b This is a perspective view of the housing 140, the first position sensor 170, and the circuit board 190.

[0161] Reference Figure 5a and Figure 5b The housing 140 can be disposed inside the cover member 300 and between the cover member 300 and the winding frame 110. The housing 140 can receive the winding frame 110 therein.

[0162] The outer surface of the housing 140 can be spaced apart from the inner surface of the side plate of the cover member 300, and the housing 140 can be moved in the space between the housing 140 and the cover member 300 by OIS drive.

[0163] The housing 140 may typically have a hollow column shape that includes an opening or a hollow portion.

[0164] For example, housing 140 may have a polygonal (e.g., quadrilateral or octagonal) or circular opening. For example, the opening of housing 140 may be a through hole in which winding frame 110 is received.

[0165] The housing 140 may include a plurality of side portions 141-1 to 141-4 and a plurality of corner portions 142-1 to 142-4.

[0166] For example, the housing 140 may include first side portions 141-1 to fourth side portions 141-4 and first corner portions 142-1 to fourth corner portions 142-4.

[0167] The first side portions 141-1 to the fourth side portions 141-4 of the housing 140 may be spaced apart from each other. Each of the corner portions 142-1 to 142-4 of the housing 140 may be arranged or positioned between two adjacent side portions 141-1 and 141-2, between two adjacent side portions 141-2 and 141-3, between two adjacent side portions 141-3 and 141-4, or between two adjacent side portions 141-4 and 141-1, and each of the corner portions 142-1 to 142-4 of the housing 140 may connect the side portions 141-1 to 141-4 to each other.

[0168] For example, corner portions 142-1 to 142-4 of housing 140 may be located at the corners of housing 140. For example, the number of side portions of housing 140 may be four, and the number of corner portions of housing 140 may be four. However, this disclosure is not limited thereto.

[0169] Each of the side portions 141-1 to 141-4 of the housing 140 can be arranged parallel to the corresponding side plate in the side plate of the cover member 300.

[0170] The horizontal length of each of the side portions 141-1 to 141-4 of the housing 140 may be greater than the horizontal length of each of the corner portions 142-1 to 142-4 of the housing 140. However, this disclosure is not limited thereto.

[0171] The first side portion 141-1 and the second side portion 141-2 of the housing 140 may be positioned opposite or facing each other, and the third side portion 141-3 and the fourth side portion 141-4 may be positioned opposite or facing each other. Each of the third side portion 141-3 and the fourth side portion 141-4 of the housing 140 may be positioned between the first side portion 141-1 and the second side portion 141-2.

[0172] The housing 140 may have a stop 144 provided on its upper portion, upper end or upper surface to prevent direct collision with the inner surface of the upper plate of the cover member 300.

[0173] For example, a stop 144 may be provided on the upper surface (e.g., the first surface 51a) of each of the corner portions 142-1 to 142-4 of the housing 140. However, this disclosure is not limited thereto.

[0174] Additionally, the housing 140 may have a guide protrusion 146 on the upper part, upper end, or upper surface of each of its corner portions 142-1 to 142-4, the guide protrusion 146 being configured to guide a damper coated on the support member 220.

[0175] The housing 140 may have at least one first connecting portion on its upper portion, upper end, or upper surface, which is connected to the first outer frame 152 of the upper elastic member 150. In addition, the housing 140 may have at least one second connecting portion on its lower portion, lower end, or lower surface, which is connected to and fixed to the second outer frame 162 of the lower elastic member 160.

[0176] Each of the first and second connecting portions of the housing 140 may be a plane, a recess, or a protrusion.

[0177] By heat fusion or the use of adhesive, the first connecting portion of the housing 140 can be connected to the hole 152a of the first outer frame 152 of the upper elastic member 150, and the second connecting portion of the housing 140 can be connected to the hole 162a of the second outer frame 162 of the lower elastic member 160.

[0178] The housing 140 may include a first seating portion 141a and a second seating portion 141b. The first seating portion 141a is disposed in one of two side portions (e.g., the first side portion 141-1) positioned opposite each other, such that a first magnet 130-1 is disposed in the first seating portion 141a. The second seating portion 141b is disposed in the other side portion 141-2 of the two side portions, such that a second magnet 130-2 is disposed in the second seating portion 141b.

[0179] Additionally, the housing 140 may include a third seating portion 141c and a fourth seating portion 141d. The third seating portion 141c is disposed in one of two other side portions (e.g., the third side portion 141-3) that are positioned opposite each other, such that the third magnet 130-3 is arranged in the third seating portion 141c. The fourth seating portion 141d is disposed in the other side portion 141-4 of the other two side portions, such that the dummy member 135 is arranged in the fourth seating portion 141d.

[0180] Each of the first seating portion 141a to the third seating portion 141c of the housing 140 may be disposed in the inner surface of a corresponding side portion of the side portion of the housing 140. However, this disclosure is not limited thereto. Each of the first seating portion 141a to the third seating portion 141c of the housing 140 may be disposed in the outer surface of a corresponding side portion of the side portion of the housing 140.

[0181] Each of the first seating portion 141a to the third seating portion 141c of the housing 140 may be a recess, such as a concave recess, having a shape corresponding to or consistent with a corresponding one of the first magnets 130-1 to the third magnets 130-3. However, this disclosure is not limited thereto.

[0182] For example, a first opening opposite to the first coil unit 120-1 (or the second coil unit 141b) and a second opening opposite to the third coil unit 230-1 (or the fourth coil unit 230-2) are formed in the first seating portion 141a (or the second seating portion 141b) of the housing 140. The openings are provided to facilitate the mounting of the magnet 130. In another embodiment, at least one of the first and second openings may be omitted.

[0183] A first opening opposite to the outer surface of the winding frame 110 and a second opening opposite to the fifth coil unit 230-3 can be formed in the third seating portion 141c of the housing 140. However, this disclosure is not limited thereto. In another embodiment, at least one of the first and second openings can be omitted.

[0184] The fourth seating portion 141d of the housing 140 may include a first opening configured to open toward the outer surface of the fourth side portion 141-4 of the housing 140 and a second opening configured to open toward the lower surface of the fourth side portion of the housing 140. However, this disclosure is not limited thereto. In another embodiment, at least one of the first and second openings may be omitted.

[0185] For example, a side surface of a magnet 130-1, 130-2, or 130-3 fixed to a mounting portion 141a, 141b, or 141c of the housing 140, or disposed in a mounting portion 141a, 141b, or 141c of the housing 140, may be exposed through a first opening in a mounting portion 141a, 141b, or 141c. Additionally, a lower surface of a magnet 130-1, 130-2, or 130-3 fixed to a mounting portion 141a, 141b, or 141c of the housing 140, or disposed in a mounting portion 141a, 141b, or 141c of the housing 140, may be exposed through a second opening in a mounting portion 141a, 141b, or 141c.

[0186] A side surface of the dummy member 135 fixed to the seat portion 141d of the housing 140 or disposed in the seat portion 141d of the housing 140 may be exposed to the outer surface of the fourth side portion 141-4 of the housing 140 through the first opening, and the lower surface of the dummy member 135 may be exposed through the second opening.

[0187] For example, the first magnet 130-1, the second magnet 130-2, and the third magnet 130-3, as well as the dummy component 135, can be fixed to the seating portions 141a to 141d respectively using adhesive.

[0188] Support members 220-1 to 220-4 may be arranged at the corner portions 142-1 to 142-4 of the housing 140. A hole 147a is provided in the corner portions 142-1 to 142-4 of the housing 140, which defines the path of extension of the support members 220-1 to 220-4.

[0189] For example, housing 140 may include a hole 147a formed through the upper portion of corner portions 142-1 to 142-4.

[0190] In another embodiment, the holes provided in the corner portions 142-1 to 142-4 of the housing 140 may be recessed from the outer surface of the corner portion of the housing 140, and at least a portion of each hole may be open toward the outer surface of the corresponding corner portion. The number of holes 147a in the housing 140 may be equal to the number of support members.

[0191] The housing 140 may be provided with at least one stop (not shown) protruding from the outer surface of the side portions 141-1 to 141-4 of the housing 140. The at least one stop can prevent the housing 140 from colliding with the cover member 300 when the cover member 300 moves in a direction perpendicular to the optical axis.

[0192] To prevent the lower surface of the housing 140 from colliding with the base 210 and / or the circuit board 250, the housing 140 may also be provided with a stop (not shown) protruding from the lower surface of the housing 140.

[0193] To ensure the extension path of the support members 220-1 to 220-4 and to ensure the space to be filled with silicone resin that can be used as a damper, the housing may have a recess 148 in the lower portion or lower end of its corner portions 142-1 to 142-4. For example, the recess 148 of the housing 140 and the hole 147a of the housing 140 may be connected to each other. For example, the lower end of the hole 147a of the housing 140 may be open toward the recess 148 of the housing 140.

[0194] The housing 140 may have a first recess 14a configured to receive a circuit board 190 and a second recess 14b configured to receive a first position sensor 170 in its fourth side portion 141-1.

[0195] To facilitate the installation of the circuit board 190, the first recess 14a of the housing 140 may be open at the upper part of the housing 140 and may have a shape that corresponds to or is consistent with the shape of the circuit board 190.

[0196] The second recess 14b may have an opening configured to open into the interior of the housing 140 and may abut or connect to the first recess 14a. However, this disclosure is not limited thereto. The second recess 14b may have a shape corresponding to or consistent with the shape of the first position sensor 170.

[0197] Next, the first magnet 130-1, the second magnet 130-2, and the third magnet 130-3 will be described.

[0198] The first magnet 130-1, the second magnet 130-2, and the third magnet 130-3 can be arranged at the housing 140 in a spaced-apart manner. For example, each of the first magnet 130-1 to the third magnet 130-3 can be arranged between the winding frame 110 and the housing 140.

[0199] The first magnet 130-1, the second magnet 130-2, and the third magnet 130-3 can be arranged on the side portion of the housing 140.

[0200] The first magnet 130-1 and the second magnet 130-2 can be arranged at two opposite side portions 141-1 and 141-2 of the side portions 141-1 to 141-4 of the housing 140, respectively.

[0201] For example, a first magnet 130-1 may be arranged at a first side portion 141-1 of the housing 140, and a second magnet 130-2 may be arranged at a second side portion 141-2 of the housing 140 opposite to the first side portion 141-1. For example, a third magnet 130-3 may be arranged at a third side portion 141-3 of the housing 140.

[0202] For example, each of the first magnet 130-1 to the third magnet 130-3 may be arranged in a corresponding one of the first seating portions 141a to the third seating portions 141c of the housing 140.

[0203] The first coil unit 120-1 and the second coil unit 120-2 for AF drive are arranged on two opposite side portions of the winding frame 110, and no coil unit for AF drive is arranged between the winding frame 110 and the third magnet 130-3. Additionally, no coil unit for AF drive is arranged between the winding frame 110 and the dummy member 135.

[0204] In addition, for OIS driving, the third coil unit 230-1 to the fifth coil unit 230-3 and the first magnet 130-1 to the third magnet 130-3 correspond to each other in the optical axis direction, and there is no second coil 230 for OIS driving arranged between the dummy member 135 and the circuit board 250.

[0205] For example, the first magnet 130-1 may include a first surface opposite to the first coil unit 120-1, and the first surface of the first magnet 130-1 may include two poles, namely an N pole and a S pole, and a first partition 11c positioned between the two poles. For example, the first partition 11c may be a non-magnetic partition.

[0206] For example, the first magnet 130-1 may include a second surface opposite to the third coil unit 230-1 in the optical axis direction, and the second surface of the first magnet 130-1 may include two poles, namely the N pole and the S pole.

[0207] For example, the second magnet 130-2 may include a first surface opposite to the second coil unit 120-2, and the first surface of the second magnet 130-2 may include two poles, namely an N pole and a S pole, and a second partition 12c positioned between the two poles. For example, the second partition 12c may be a non-magnetic partition.

[0208] For example, the second magnet 130-2 may include a second surface opposite to the fourth coil unit 230-2 in the optical axis direction, and the second surface of the second magnet 130-2 may include two poles, namely the N pole and the S pole.

[0209] For example, the third magnet 130-3 may include a first surface opposite to a side portion of the winding frame 110, which is opposite to a side portion 141-3 of the housing 140 on which the third magnet 130-3 is arranged, and the first surface of the third magnet 130-3 may include two poles, namely an N pole and an S pole.

[0210] Additionally, for example, the third magnet 130-3 may include a second surface opposite to the fifth coil unit 230-3 in the optical axis direction, and the second surface of the third magnet 130-3 may include two poles, namely an N pole and a S pole, and a third partition 13c positioned between the two poles. For example, the third partition 13c may be a non-magnetic partition 13c.

[0211] At the initial position of the AF moving unit, the first magnet 130-1 can overlap with the first coil unit 120-1 in a direction perpendicular to the optical axis and in a direction from the optical axis to the first coil unit 120-1 (or the center of the first coil unit 120-1).

[0212] At the initial position of the AF moving unit, the second magnet 130-2 can overlap with the second coil unit 120-2 in a direction perpendicular to the optical axis and in a direction from the optical axis to the second coil unit 120-2 (or the center of the second coil unit 120-2).

[0213] At the initial position of the AF moving unit, the third magnet 130-3 can be perpendicular to the optical axis and in the direction from the third side portion 141-3 to the fourth side portion 141-4 of the housing 140, and not opposite to or overlapping with the first coil unit 120-1 and the second coil unit 120-2.

[0214] For example, each of the first magnet 130-1 to the third magnet 130-3 may be arranged in a corresponding one of the first seating portions 141a to the third seating portions 141c of the housing 140.

[0215] The first magnet 130-1 may overlap with the second magnet 130-2 in a direction perpendicular to the optical axis and in a direction from the first side portion 141-1 to the second side portion 141-2 of the housing 140, and may not overlap with the third magnet 130-3.

[0216] Each of the first magnet 130-1 to the third magnet 130-3 may have a polyhedral shape, which can be easily seated or arranged in a corresponding one of the first seating portions 141a to the third seating portions 141c of the housing 140. For example, each of the first magnet 130-1 to the third magnet 130-3 may have a flat shape. However, this disclosure is not limited thereto.

[0217] Each of the first magnet 130-1 to the third magnet 130-3 can be a quadrupole magnet comprising two N poles and two S poles. Here, a quadrupole magnet can be referred to as a bipolar magnetized magnet. The first magnet 130-1 to the third magnet 130-3 will be described later.

[0218] The dummy member 135 may be disposed at the fourth side portion 141-4 of the housing 140. The dummy member 135 may be a non-magnetic material. However, this disclosure is not limited thereto. In another embodiment, the dummy member may include a magnetic material. For example, the dummy member 135 may be a metal or an insulator.

[0219] The dummy member 135 may have the same mass as the third magnet 130-3. However, this disclosure is not limited thereto. For weight balance, the dummy member 135 may be arranged at the side portion 141-1, which is positioned opposite the side portion 141-3 where the third magnet 130-3 is arranged.

[0220] At the initial position of the AF moving unit, the dummy member 135 can be in a direction perpendicular to the optical axis and in the direction from the third side portion 141-3 to the fourth side portion 141-4 of the housing 140, and not opposite to or overlapping with the first coil unit 120-1 and the second coil unit 120-2.

[0221] The dummy component 135 can overlap with the third magnet 130-3 in a direction perpendicular to the optical axis and in the direction from the third side portion 141-3 to the fourth side portion 141-4 of the housing 140.

[0222] For example, the dummy component 135 may not overlap with the first magnet 130-1 and the second magnet 130-2 in the direction from the third side portion 141-3 to the fourth side portion 141-4 of the housing 140.

[0223] Additionally, at least a portion of the dummy member 135 may overlap with the position sensor 170 in a direction perpendicular to the optical axis and in a direction from the third side portion 141-3 to the fourth side portion 141-4 of the housing 140. However, this disclosure is not limited thereto. In another embodiment, the two may not overlap each other.

[0224] When the dummy component 135 includes a magnetic material, the magnitude of the magnetism of the dummy component 135 can be smaller than the magnitude of the magnetism of the third magnet 130-3. Since the lens moving units are arranged such that the dummy components included in the lens moving units are adjacent to each other, the camera module according to the embodiment is able to reduce magnetic field interference between magnets included in two adjacent lens moving units.

[0225] For example, dummy component 135 may include tungsten, and tungsten may account for more than 95% of the total weight of dummy component 135. For example, dummy component 135 may be a tungsten alloy.

[0226] The dummy component 135 may have a polyhedral shape, such as a cuboid shape. However, this disclosure is not limited thereto. The dummy component 135 may have any shape of various shapes. For example, the dummy component 135 may be rounded or curved at its side edges.

[0227] Next, the circuit board 190 and the first position sensor 170 will be described.

[0228] The first position sensor 170 and the circuit board 190 are arranged on one side of the side portion of the housing 140. For example, the first position sensor 170 and the circuit board 190 may be arranged on the fourth side portion 141-4 of the housing 140 where the dummy member 135 is arranged. This arrangement is provided to avoid spatial interference between the first magnet 130-1 to the third magnet 130-3 and the circuit board 190 on which the first position sensor 170 is mounted.

[0229] For example, circuit board 190 may be arranged at the first recess 14a of housing 140, and first position sensor 170 may be arranged or mounted on circuit board 190.

[0230] At the initial position of the AF moving unit, at least a portion of the first position sensor 170 may overlap with the sensing magnet 180 in a direction perpendicular to the optical axis and in the direction from the optical axis to the first position sensor 170. However, this disclosure is not limited thereto.

[0231] The first position sensor 170 can be disposed on the first surface of the circuit board 190. Here, the first surface of the circuit board 190 mounted to the housing 140 can be the surface opposite to the interior of the housing 140 (or the outer surface of the winding frame 110).

[0232] The first position sensor 170 can be configured as a driver integrated circuit (IC) that includes a Hall sensor, or it can be implemented simply as a position sensor such as a Hall sensor.

[0233] When the first position sensor 170 is implemented as a Hall sensor, it may include two input terminals and two output terminals. Each of the input and output terminals of the first position sensor 170 may be connected to a corresponding one of the first to fourth pads of the circuit board 190.

[0234] For example, circuit board 190 can be a printed circuit board or an FPCB.

[0235] For example, the first to fourth terminals of circuit board 190 can be connected to upper springs 150-1 to 150-4 respectively, and can be connected to circuit board 250 via support members 220-1 to 220-4. The first position sensor 170 can be connected to circuit board 250. For example, the two input terminals and two output terminals of the first position sensor 170 can be connected to the terminals of circuit board 250 via circuit board 190, upper springs 150-1 to 150-4, and support members 220-1 to 220-4.

[0236] In the case where the first position sensor 170 is a driver IC that includes a Hall sensor, the first position sensor may include four terminals configured to transmit and receive clock signal SCL, data signal SDA, and power signals VCC and GND, and two terminals configured to provide drive signals to the first coil 120.

[0237] Next, the upper elastic member 150, the lower elastic member 160, the support member 220, the second coil 230, the circuit board 250, and the base 210 will be described.

[0238] Figure 6 This is a plan view of the upper elastic member 150. Figure 7 This is a view showing the electrical connections between the upper elastic member 150, the first position sensor 170, and the support member 220. Figure 8 This is a bottom view of the lower elastic member 160 and the housing 140. Figure 9a This is a separate perspective view of the base 210, the second coil 230, and the circuit board 250. Figure 9bAnother embodiment including a second position sensor 240 is shown.

[0239] Reference Figures 6 to 9a The upper elastic member 150 can be connected to the upper part, upper surface, or upper end of the winding frame 110, and can also be connected to the upper part, upper surface, or upper end of the housing 140. The elastic member 160 can be connected to the lower part, lower surface, or lower end of the winding frame 110, and can also be connected to the lower part, lower surface, or lower end of the housing 140.

[0240] The upper elastic member 150 and the lower elastic member 160 can constitute an elastic member. The elastic member can be connected to the winding frame and the housing. The elastic member can elastically support the winding frame 110 relative to the housing 140.

[0241] The upper elastic member 150 may include a plurality of upper springs 150-1 to 150-4, which are separated from each other. Figure 6 The image shows four upper springs that are separated from each other. However, this disclosure is not limited thereto. In another embodiment, the number of upper springs may be two or more.

[0242] For example, the first upper spring 150-1 can be arranged on the first corner portion 142-1 and the fourth side portion 141-4 of the housing 140.

[0243] For example, the second upper spring 150-2 can be arranged on the fourth side portion 141-4 and the second corner portion 142-2 of the housing 140.

[0244] For example, the third upper spring 150-3 can be arranged on the second corner portion 142-2, the second side portion 141-2 and the third corner portion 142-3 of the housing 140.

[0245] For example, the fourth upper spring 150-4 can be arranged on the fourth corner portion 142-4, the first side portion 141-1, and the first corner portion 142-1 of the housing 140.

[0246] At least one of the first upper spring 150-1 to the fourth upper spring 150-4 may further include: a first inner frame 151 connected to the winding frame 110, a first outer frame 152 connected to the housing 140, and a first frame connecting portion 153 configured to connect the first inner frame 151 and the first outer frame 152 to each other. In another embodiment, the inner frame may be referred to as the "inner portion", the outer frame 152 may be referred to as the "outer portion", and the frame connecting portion may be referred to as the "connecting portion".

[0247] For example, each of the first upper spring 150-1 and the second upper spring 150-2 may include a first outer frame 152 and may not include a first inner frame and a first frame connecting portion. Each of the third upper spring 150-3 and the fourth upper spring 150-4 may include a first inner frame 151, a first outer frame 152, and a first frame connecting portion 153. However, this disclosure is not limited thereto.

[0248] For example, the first inner frame 151 may be provided with a hole 151a, into which the first connecting portion of the winding frame 110 is connected. Alternatively, for example, the first outer frame 152 may be provided with a hole 152a, into which the first connecting portion of the housing 140 is connected.

[0249] The first outer frame 152 of the first upper spring 150-1 to the fourth upper spring 150-4 may have contact portions P1 to P4 respectively connected to terminals of the circuit board 190.

[0250] The first outer frame 152 of each of the first upper springs 150-1 to the fourth upper springs 150-4 may include: a first connecting portion 510 connected to a corresponding one of the support members 220-1 to 220-4, a second connecting portion 520 connected to a corresponding corner portion of the corner portion of the housing 140, and a connecting portion 530 configured to connect the first connecting portion 510 and the second connecting portion 520 to each other.

[0251] For example, the connecting portion 530 may include: a first connecting portion 530-1 configured to connect a first region of the first connecting portion 510 to the second connecting portion 520; and a second connecting portion 530-2 configured to connect a second region of the first connecting portion 510 to the second connecting portion 520. The connecting portion 530 may include a portion that is bent or folded at least once.

[0252] The lower elastic member 160 may include two lower springs. However, this disclosure is not limited thereto. In another embodiment, the lower elastic member may include a single lower spring or three or more lower springs.

[0253] For example, each of the first lower spring 160-1 and the second lower spring 160-2 may include: a second inner frame 161, which is coupled or fixed to the lower portion, lower surface, or lower end of the winding frame 110; a second outer frame 162, which is coupled or fixed to the lower portion, lower surface, or lower end of the housing 140; and a second frame connecting portion 163, which is configured to connect the second inner frame 161 and the second outer frame 162 to each other.

[0254] Each of the first frame connecting portion 153 of the upper elastic member 150 and the second frame connecting portion 163 of the lower elastic member 160 can be configured to bend or flex (or distort) at least once to form a predetermined pattern. The upward and / or downward movement of the winding frame 110 along the first direction can be flexibly (or elastically) supported by positional changes and minor deformations of the first frame connecting portion 153 and the second frame connecting portion 163.

[0255] The second inner frame 161 may be provided with a hole 161a, and the second connecting part of the winding frame 110 is connected to the hole 161a. The second outer frame 162 may be provided with a hole 162a, and the second connecting part of the housing 140 is connected to the hole 162a.

[0256] Each of the upper springs 150-1 to 150-4 and the lower springs 160-1 and 160-2 can be implemented as a leaf spring; however, this disclosure is not limited thereto. Each of the upper and lower springs can be implemented as a coil spring, etc. In addition, for the upper and lower springs, "spring" can be referred to as "elastic element".

[0257] In order to absorb or reduce the vibration of the winding frame 110, the lens moving device 100 may also include a first damper (not shown) arranged between each of the upper springs 150-1 to 150-4 and the winding frame 110 (or housing 140).

[0258] For example, a first damper (not shown) may be arranged in the space between the first frame connection portion 153 of each of the upper springs 150-1 to 150-4 and the winding frame 110.

[0259] Additionally, for example, the lens moving device 100 may also include a second damper (not shown) disposed between the second frame connection portion 163 of the lower elastic member 160 and the winding frame 110 (or housing 140).

[0260] Additionally, for example, the lens moving device 100 may also include a third damper (not shown) arranged between the support member 220 and the hole 147a of the housing 140.

[0261] Additionally, for example, the lens moving device 100 may also include a fourth damper (not shown) arranged at one end of the first connecting portion 510 and the support member 220, and may also include a fifth damper (not shown) arranged at the other end of the support member 220 and the circuit board 250.

[0262] Alternatively, for example, a damper (not shown) may be arranged between the inner surface of the housing 140 and the outer surface of the winding frame 110.

[0263] Next, the support member 220 will be described.

[0264] The support member 220 can support the housing 140 so that it can move relative to the base 210 in a direction perpendicular to the optical axis. The support member 220 can connect at least one of the upper elastic member 150 and the lower elastic member 160 to the circuit board 250.

[0265] The support member 220 may include a plurality of support members 220-1 to 220-4.

[0266] For example, the support members may include a first support member 220-1 to a fourth support member 220-4 corresponding to the corner portions 142-1 to 142-4 of the housing 140.

[0267] Each of the first support member 220-1 to the fourth support member 220-4 can be arranged at a corresponding one of the first corner portions 142-1 to the fourth corner portions 142-4 of the housing 140, and a corresponding one of the first upper spring 150-1 to the fourth upper spring 150-4 can be connected to the circuit board 250.

[0268] For example, each of the first support member 220-1 to the fourth support member 220-4 can connect a corresponding one of the first upper spring 150-1 to the fourth upper spring 150-4 to a corresponding terminal of the circuit board 250.

[0269] The first support member 220-1 to the fourth support member 220-4 may be spaced apart from the housing 140, rather than fixed to the housing 140, and one end of each of the first support member 220-1 to the fourth support member 220-4 may be directly connected or coupled to the first connecting portion 510 of the corresponding one of the first upper springs 150-1 to the fourth upper springs 150-4 by welding.

[0270] Additionally, the other end of each of the first support members 220-1 to the fourth support member 220-4 can be directly connected or coupled to the circuit board 250 by soldering. For example, the other end of each of the first support members 220-1 to the fourth support member 220-4 can be directly connected or coupled to the lower surface of the circuit board 250. In another embodiment, the other end of each of the support members 220-1 to 220-4 can be coupled to the circuit member 231 or the base 210 of the second coil 230.

[0271] For example, each of the first support members 220-1 to the fourth support member 220-4 may extend through a hole 147a formed in a corresponding one of the corner portions 142-1 to 142-4 of the housing 140. However, this disclosure is not limited thereto. In another embodiment, the support member may be arranged adjacent to the boundary between the side portions 141-1 to 141-4 of the housing 140 and the corner portion 142, and may not extend through the corner portions 142-1 to 142-4 of the housing 140.

[0272] The first coil 120 can be connected to the lower elastic member 150.

[0273] In the case where the first coil unit 120-1 and the second coil unit 120-2 are connected to each other (Case 1), one end of the first coil unit 120-1 may be connected or coupled to the second inner frame 161 of one of the first lower springs 160-1 to the fourth lower spring 160-4 (e.g., 160-2), and one end of the second coil unit 120-2 may be connected or coupled to the second inner frame 161 of the other of the first lower springs 160-1 to the fourth lower spring 160-4 (e.g., 160-4).

[0274] When the first position sensor 170 is implemented as a position sensor, such as a Hall sensor, in CASE1, the two lower springs (e.g., 160-2 and 160-4) connected to the first coil unit 120-1 and the second coil unit 120-2 can be connected to the terminals of the circuit board 250, and separate drive signals can be provided to the first coil unit 120-1 and the second coil unit 120-2 through the circuit board 250.

[0275] When the first position sensor 170 is configured in CASE1 as a driver integrated circuit (IC) including a Hall sensor, two lower springs (e.g., 160-2 and 160-4) connected to the first coil unit 120-1 and the second coil unit 120-2 can be connected to the first position sensor 170, and a single drive signal can be provided to the first coil unit 120-1 and the second coil unit 120-2 through the first position sensor 170.

[0276] In another embodiment (case 2) in which the first coil unit 120-1 and the second coil unit 120-2 are separated from each other, the first coil unit 120-1 may be connected or coupled to the second inner frame of two of the first lower springs 160-1 to the fourth lower springs 160-4 (e.g., 160-1 and 160-2), and the second coil unit 120-2 may be connected or coupled to the second inner frame of the other two of the first lower springs 160-1 to the fourth lower springs 160-4 (e.g., 160-3 and 160-4).

[0277] When the first position sensor 170 is implemented as a position sensor, such as a Hall sensor, in CASE2, the first lower spring 160-1 to the fourth lower spring 160-4 can be connected to the circuit board 250. For example, the first lower spring 160-1 to the fourth lower spring 160-4 can be connected to the terminals of the circuit board 250, and a single drive signal (e.g., drive current) can be provided to the first coil unit 120-1 and the second coil unit 120-2 through the circuit board 250.

[0278] When the first position sensor 170 is configured in CASE2 as a driver integrated circuit (IC) including a Hall sensor, the first lower spring 160-1 to the fourth lower spring 160-4 can be connected to the first position sensor 170, and a single drive signal (e.g., drive current) can be provided to the first coil unit 120-1 and the second coil unit 120-2 through the first position sensor 170.

[0279] The support member 220 can be implemented as an elastic support member such as a suspension wire, leaf spring, or coil spring. Alternatively, in another embodiment, the support member 220 can be integrally formed with the upper elastic member 150.

[0280] Next, the base 210, the circuit board 250, and the second coil 230 will be described.

[0281] Reference Figure 9a The base 210 can be arranged below the winding frame 110 (or housing 140).

[0282] The base 210 may have an opening corresponding to the opening of the winding frame 110 and / or the opening of the housing 140, and may be formed in a shape that is consistent with or corresponds to the shape of the cover member 300, such as a quadrilateral.

[0283] The support portion 255 or the support portion may be provided in the area of ​​the base 210 opposite to the terminals 251 of the circuit board 250. The support portion 255 of the base 210 may support the terminal portion of the terminal surface 253 of the circuit board 250 on which the terminals 251 are formed.

[0284] The base 210 may have a concave recess 212 in each of its corner portions to avoid spatial interference with the connection of one of the support members 220-1 to 220-4 to the other end of the circuit board 250.

[0285] Additionally, the base 210 may have a protrusion 19 on its upper surface around its opening, which is connected to the opening of the circuit board 250 and the opening 231a of the circuit member 231.

[0286] Additionally, the base 210 may have a mounting portion (not shown) on its lower surface, in which a filter 610 of the camera module 200 is mounted.

[0287] The circuit board 250 is disposed on the upper surface of the base 210 and may have openings corresponding to the openings of the winding frame 110, the housing 140, and / or the base 210. The circuit board 250 may be formed in a shape that is consistent with or corresponds to the shape of the upper surface of the base 210, such as a quadrilateral.

[0288] The circuit board 250 may have at least one terminal surface 253 that bends from the upper surface of the circuit board 250, and a plurality of terminals 251 or pins configured to receive electrical signals from the outside are provided on the terminal surface 253. For example, the circuit board 250 may include two terminal surfaces arranged on two opposite sides of the upper surface of the circuit board 250. However, this disclosure is not limited thereto.

[0289] Drive signals can be provided to the first coil 120 and the second coil 230 through multiple terminals 251 disposed on the terminal surface 253 of the circuit board 250. In addition, drive signals can be provided to the first position sensor 170 through the terminals 251 of the circuit board 250, and the output signals of the first position sensor 170 can be received and output. Drive signals can be provided to the second position sensor 240, and the output signals of the second position sensor 240 can be received and output.

[0290] The drive signal provided to the first coil 120 and / or the second coil 230 can be a DC signal or an AC signal, and can be in the form of current or voltage.

[0291] The circuit board 250 may be an FPCB. However, this disclosure is not limited thereto. The terminals of the circuit board 250 may be formed directly on the surface of the base 210 using a surface electrode scheme or the like.

[0292] To avoid spatial interference with the support members, the circuit board 250 may include holes 250a extending through the support members 220-1 to 220-4. The position and number of holes 250a may correspond to or be consistent with the position and number of support members 220-1 to 220-4.

[0293] In another embodiment, the circuit board 250 may have an avoidance recess in its corner portion instead of a hole 250a.

[0294] For example, support members 220-1 to 220-4 may extend through holes 250a in the circuit board 250 and may be connected via solder to a circuit pattern disposed on the lower surface of the circuit board 250. However, this disclosure is not limited thereto.

[0295] In another embodiment, the circuit board 250 may not have holes, and the support members 220-1 to 220-4 may be connected via solder to a circuit pattern or pad disposed on the upper surface of the circuit board 250.

[0296] In another embodiment, support members 220-1 to 220-4 may be connected to circuit member 231, and circuit member 231 may connect support members 220-1 to 220-4 to circuit board 250.

[0297] The second coil 230 can be arranged below the winding frame 110 (or housing) and on the upper surface of the circuit board 250.

[0298] The second coil 230 may include a third coil unit 230-1 corresponding to the first magnet 130-1 arranged in the housing 140, a fourth coil unit 230-2 corresponding to the second magnet 130-2, and a fifth coil unit 230-3 corresponding to the third magnet 130-3.

[0299] For example, the third coil unit 230-1 may be opposite to or overlap with the first magnet 130-1 in the optical axis direction, the fourth coil unit 230-2 may be opposite to or overlap with the second magnet 130-2 in the optical axis direction, and the fifth coil unit 230-3 may be opposite to or overlap with the third magnet 130-3 in the optical axis direction.

[0300] Each of the third coil unit 230-1 to the fifth coil unit 230-3 may have a closed curve shape, such as a ring shape, including a central hole, and the central hole may be formed to face the optical axis direction.

[0301] For example, the third coil unit 230-1 and the fourth coil unit 230-2 can be arranged to face each other in the direction from the first magnet 130-1 to the second magnet 130-2.

[0302] Additionally, for example, each of the third coil unit 230-1 and the fourth coil unit 230-2 may not overlap with the fifth coil unit 230-3 in the direction from the first magnet 130-1 to the second magnet 130-2.

[0303] For example, the second coil 230 may also include a quadrilateral circuit member 231, with the third coil unit 230-1 to the fifth coil unit 230-3 formed at the quadrilateral circuit member 231.

[0304] Here, circuit component 231 can be referred to as a "substrate," and substrate 231 may include a second coil 230. Alternatively, for example, first coil unit 120-1 can be referred to as a first coil. Second coil unit 120-2 can be referred to as a second coil, and second coil 230 can be referred to as a third coil. In this case, substrate 231 may include a third coil.

[0305] For example, circuit component 231 may include four sides 23a to 23d (see Figure 11 It may include an opening 231a corresponding to the opening of the housing 140, the opening of the circuit board 250 and / or the opening of the base 210.

[0306] Each of the third coil unit 230-1 to the fifth coil unit 230-3 may be arranged on one of the three sides of the circuit member 231, and no coil unit may be arranged on the remaining side of the circuit member 231.

[0307] For example, each of the third coil unit 230-1 and the fifth coil unit 230-2 may be arranged parallel to one of the opposing first and second sides of the circuit member 231, and the fifth coil unit 230-3 may be arranged parallel to the third or fourth side of the circuit member 231.

[0308] To avoid spatial interference with support members 220-1 to 220-4, a hole 230a can be provided in the corner of circuit member 231, and support members 220-1 to 220-4 can extend through the hole 230a of circuit member 231. In another embodiment, the circuit member can have a recess at its corner instead of a hole to avoid spatial interference with the support member.

[0309] The third coil unit 230-1 to the fifth coil unit 230-3 can be connected to the circuit board 250. For example, each of the third coil unit 230-1 to the fifth coil unit 230-3 can be connected to a corresponding terminal of the circuit board 250.

[0310] The circuit board 250 may include a bonding portion or pad connected to the third coil unit 230-1 to the fifth coil unit 230-3, and the bonding portion or pad of the circuit board 250 may be connected to the terminals of the circuit board 250.

[0311] In Figure 9, the third coil unit 230-1 to the fifth coil unit 230-3 may be formed at the circuit component 231 instead of at the circuit board 250. However, this disclosure is not limited thereto. In another embodiment, each of the third coil unit 230-1 to the fifth coil unit 230-3 may be configured as a ring coil block or an FP coil. In yet another embodiment, each of the third coil unit 230-1 to the fifth coil unit 230-3 may be configured as a circuit pattern formed on the circuit board 250.

[0312] Circuit board 250 and circuit member 231 are separate components mentioned separately. However, this disclosure is not limited thereto. In another embodiment, circuit board 250 and circuit member 231 may be collectively referred to as "circuit member". In this case, the other end of each of the support members may be connected to the "circuit member" (e.g., the lower surface of the circuit member).

[0313] Reference Figure 9b The lens moving device 100 may further include a second position sensor 240 for OIS feedback driving. The second position sensor 240 may include a first sensor 240a and a second sensor 240b.

[0314] Each of the first sensor 240a and the second sensor 240b can be a Hall sensor, and any sensor can be used as long as it can sense the magnitude of the magnetic field. For example, each of the first sensor 240a and the second sensor 240b can be configured as a driver that includes a Hall sensor, or it can be implemented simply as a position sensor such as a Hall sensor.

[0315] For example, the first sensor 240a and the second sensor 240b can be arranged or mounted on the lower surface of the circuit board 250, and seating recesses 215-1 and 215-2 can be provided in the upper surface of the base 210, and the first sensor 240a and the second sensor 240b can be arranged in the seating recesses 215-1 and 215-2 of the base 210. However, this disclosure is not limited thereto. In another embodiment, the first sensor and the second sensor can be arranged on the upper surface of the circuit board 250.

[0316] The first sensor 240a can be arranged to be opposite to or overlap with one of the first magnet 130-1 and the second magnet 130-2 in the optical axis direction.

[0317] The second sensor 240b can be arranged opposite to or overlapping the third magnet 130-3 in the optical axis direction.

[0318] The first sensor 240a and the second sensor 240b can be connected to the terminals of the circuit board 250. For example, a drive signal can be provided to the first sensor 240a and the second sensor 240b through the terminals of the circuit board 250, and the first output of the first sensor 240a and the second output of the second sensor 240b can be output through the terminals of the circuit board 250.

[0319] The controller 830 of the camera module 200 or the controller 780 of the terminal 200A can use the first output of the first sensor 240a and the second output of the second sensor 240b to sense or detect the displacement of the OIS moving unit.

[0320] For example, the first sensor 240a and the second sensor 240b may be arranged or mounted on the lower surface of the circuit board 250, and may be arranged in the seating recesses 215-1 and 215-2 of the base 210. However, this disclosure is not limited thereto.

[0321] The first sensor 240a and the second sensor 240b can sense the displacement of the OIS moving unit along a direction perpendicular to the optical axis OA.

[0322] Due to the interaction between the first magnet 130-1 and the third coil unit 230-1, the interaction between the second magnet 130-2 and the fourth coil unit 230-2, and the interaction between the third magnet 130-3 and the fifth coil unit 230-3, the OIS moving unit (e.g., housing 140) can move along a direction perpendicular to the optical axis OA, such as along the X-axis and / or Y-axis, thereby enabling hand shake compensation.

[0323] Next, the cover component 300 will be described.

[0324] The cover member 300 can accommodate the OIS moving unit, the upper elastic member 150, the lower elastic member 160, the second coil 230, the circuit board 250, the support member 220, and the second position sensor 240 in a receiving space formed together with the base 210.

[0325] The cover member 300 can be formed in the shape of a box, the lower part of the cover member 300 is open, and the cover member 300 includes a top plate and side plates. The lower part of the cover member 300 can be connected to the upper part of the base 210. The shape of the top plate of the cover member 300 can be polygonal, such as quadrilateral or octagonal.

[0326] The cover member 300 may have an opening in its upper plate through which a lens (not shown) connected to the winding frame 110 is exposed to external light. The cover member 300 may be made of a non-magnetic material such as SUS to prevent the magnet 130 from attracting the cover member. The cover member 300 may be made of metal. However, this disclosure is not limited thereto. The cover member may be made of plastic. Additionally, the cover member 300 may be connected to the ground of the second retainer 800 of the camera module 200. The cover member 300 may block electromagnetic interference (EMI).

[0328] Reference Figures 10a to 14 The first magnet 130-1 and the second magnet 130-2 may have the same length, width, and height. However, this disclosure is not limited thereto. Additionally, the third coil unit 230-1 and the fourth coil unit 230-2 may have the same length, width, and height. However, this disclosure is not limited thereto.

[0329] Reference Figure 12 and Figure 13 The length L1, width W1, and height H1 of the first magnet 130-1, the length L2, width W2, and height H2 of the second magnet 130-2, and the length L3, width W3, and height H3 of the dummy member 135 will be described. Additionally, the lengths M1 and M2, widths K1 and K2, and heights (length or thickness in the optical axis direction) of the third coil unit 230-1 to the fifth coil unit 230-3 will also be described.

[0330] Here, the lengths L1 and L2 of the first magnet 130-1 to the third magnet 130-3 can be the lengths of the first magnet 130-1 to the third magnet 130-3 in the longitudinal direction, and the length L3 of the dummy member 135 can be the length of the dummy member 135 in the longitudinal direction. Additionally, the widths W1 and W2 of the first magnet 130-1 to the third magnet 130-3 can be the lengths of the first magnet 130-1 to the third magnet 130-3 in the width direction, and the width W3 of the dummy member 135 can be the length of the dummy member 135 in the width direction.

[0331] Here, the width direction can be perpendicular to the longitudinal direction and can be the direction of the smaller length of each of parts 130-1 to 130-3 and 135. In addition, the width of each of parts 130-1 to 130-3 and 135 can be referred to as the “thickness” of each of parts 130-1 to 130-3 and 135.

[0332] For example, the lengths L1 and L2 of the first magnet 130-1 to the third magnet 130-3 can be the lengths of the first surfaces of the first magnet 130-1 to the third magnet 130-3 in the longitudinal direction opposite to the winding frame 110. Additionally, the length L3 of the dummy member 135 can be the length of the first surface of the dummy member 135 in the longitudinal direction opposite to the winding frame 110.

[0333] Additionally, for example, the widths W1, W2, and W3 of the first magnet 130-1 to the third magnet 130-3 and the dummy member 135 can be the distance from the first surface of the members 130-1 to 130-3 and 135 opposite to the winding frame 110 to the second surface of the members 130-1 to 130-3 and 135 opposite to the first surface.

[0334] Additionally, for example, the heights H1 and H2 of the first magnet 130-1 to the third magnet 130-3 and the height H3 of the dummy member 135 can be the length of the component in the optical axis direction.

[0335] Additionally, for example, heights H1, H2, and H3 can be the lengths in the vertical direction of the first surfaces of components 130-1 to 130-3 and 135 opposite to the winding frame 110. Additionally, for example, heights H1, H2, and H3 can be the distances from the lower surface to the upper surface of the first surfaces of components 130-1 to 130-3 and 135.

[0336] Each of the lengths M1 and M2 of the third coil unit 230-1 to the fifth coil unit 230-3 can be the length in the longitudinal direction of the corresponding one of the first magnet 130-1 to the third magnet 130-3 or in a direction parallel to that longitudinal direction. For example, M1 and M2 can be the lengths of the third coil unit 230-1 to the fifth coil unit 230-3 in the longitudinal direction, and each of M1 and M2 can be the length between the outermost ends of each of the third coil unit 230-1 to the fifth coil unit 230-3.

[0337] In addition, the lengths X1, X2 and Y1 of the third coil unit 230-1 to the fifth coil unit 230-3 can be the lengths between the outermost ends of the inner portion (or inner surface) of each of the third coil unit 230-1 to the fifth coil unit 230-3.

[0338] In addition, each of the widths K1 and K2 of the third coil unit 230-1 to the fifth coil unit 230-3 can be the length in the width direction of the corresponding one of the first magnets 130-1 to the third magnet, or in a direction parallel to that width direction.

[0339] The height of each of the third coil units 230-1 to the fifth coil units 230-3 may be its length in the optical axis direction, and the heights of the third coil units 230-1 to the fifth coil units 230-3 may be the same. However, this disclosure is not limited thereto. In another embodiment, the height of at least one of the third coil units 230-1 to the fifth coil units 230-3 may be different from the other heights.

[0340] The length L1 of the first magnet 130-1 can be less than the lengths M1 and X1 of the third coil unit 230-1 (L1 < M1, X1). The length W1 of the first magnet 130-1 in the width direction can be less than the length K1 of the third coil unit 230-1 in the width direction (W1 < K1).

[0341] In addition, the length of the second magnet 130-2 can be less than the lengths M1 and X2 of the fourth coil unit 230-2. The length of the second magnet 130-2 in the width direction can be less than the length of the fourth coil unit 230-2 in the width direction.

[0342] The length L2 of the third magnet 130-3 can be less than the lengths M2 and Y1 of the fifth coil unit 230-3 (L2 < M2, Y1). The length W2 of the third magnet 130-3 in the width direction can be less than the length K2 of the fifth coil unit 230-3 in the width direction (W2 < K2). In another embodiment, W2 and K2 can be equal to each other.

[0343] The length M2 of the fifth coil unit 230-3 in the longitudinal direction can be greater than the length M1 of the third coil unit 230-1 in the longitudinal direction and / or the length of the fourth coil unit 230-2 in the longitudinal direction (M2 > M1). In addition, the length Y1 of the fifth coil unit 230-3 can be greater than the length X1 of the third coil unit 230-1 and / or the length X2 of the fourth coil unit 230-2 (Y1 > X1, X2).

[0344] In addition, for example, the length X1 of the third coil unit 230-1 and the length X2 of the fourth coil unit 230-2 can be equal to each other (X1 = X2).

[0345] The length L2 of the third magnet 130-3 can be greater than the length L1 of the first magnet 130-1 and / or the length of the second magnet 130-2 (L2 > L1).

[0346] Since M2 > M1 and L2 > L1, the first electromagnetic force generated by the fifth coil unit 230-3 and the third magnet 130-3 can be greater than the second electromagnetic force generated by the third coil unit 230-1 and the first magnet 130-1, and can be greater than the third electromagnetic force generated by the fourth coil unit 230-2 and the second magnet 130-2. As a result, this embodiment can reduce the difference between the first electromagnetic force in the X-axis direction and the sum of the second and third electromagnetic forces in the Y-axis direction, thereby improving the reliability in OIS operation.

[0347] In another embodiment, M2 = M1 and L2 = L1.

[0348] For example, L1:L2 = 1:1 to 1:1.5. Alternatively, for example, L1:L2 = 1:1.2 to 1:1.4.

[0349] Furthermore, the length K2 of the fifth coil unit 230-3 in the width direction may be greater than the length K1 of the third coil unit 230-1 in the width direction and / or the length of the fourth coil unit 230-2 in the width direction (K2>K1). However, this disclosure is not limited thereto. In another embodiment, the two may be equal to each other.

[0350] The length W2 of the first magnet 130-1 in the width direction may be greater than the length W1 of the first magnet 130-1 in the width direction and / or the length of the second magnet 130-2 in the width direction (W2>W1). However, this disclosure is not limited thereto. In another embodiment, W2 = W1.

[0351] For example, W1 can be the length in a direction perpendicular to the optical axis and one surface of the first magnet 130-1 (or the second magnet 130-2), and W2 can be the length in a direction perpendicular to the optical axis and one surface of the third magnet 130-3.

[0352] Since W2 > W1, this implementation can reduce the difference between the first electromagnetic force in the X-axis direction and the sum of the second and third electromagnetic forces in the Y-axis direction, thereby improving the reliability of OIS operation.

[0353] The height H2 of the third magnet 130-3 can be equal to the height H1 of the first magnet 130-1 and / or the height of the second magnet 130-2 (H2 = H1). Here, H1 and H2 can be the lengths of magnets 130-1 to 130-3 along the optical axis. Alternatively, H1 can be the distance from the lower surface to the upper surface of the first magnet 130-1 (or the second magnet 130-2), and H2 can be the distance from the lower surface to the upper surface of the third magnet 130-3.

[0354] That is, the length of the third magnet 130-3 in the optical axis direction can be equal to the length of the first magnet 130-1 in the optical axis direction and / or the length of the second magnet 130-2 in the optical axis direction.

[0355] Alternatively, for example, the length of the first magnet 130-1 in the optical axis direction and the length of the second magnet 130-2 in the optical axis direction can be equal to each other.

[0356] Reference Figure 11 Each of the third coil unit 230-1 to the fifth coil unit 230-3 may have an annular shape including an opening in the optical axis direction.

[0357] The length L3 of the dummy member 135 can be less than the length L2 of the third magnet 130-3 in the longitudinal direction (L3 < L2), and the length W3 of the dummy member 135 in the width direction can be less than the length W2 of the third magnet 130-3 in the width direction (W3 < W2).

[0358] Since W3 < W2, this embodiment can ensure sufficient space for arranging the circuit board 190 and the first position sensor 170, thereby preventing spatial interference between the circuit board 190 and the first position sensor 170 and the dummy member 135.

[0359] In another embodiment, W3 = W2 and L2 = L3.

[0360] In addition, the first distance in the optical axis direction between the first magnet 130-1 and the third coil unit 230-1, the second distance in the optical axis direction between the second magnet 130-2 and the fourth coil unit 230-2, and the third distance in the optical axis direction between the third magnet 130-3 and the fifth coil unit 230-2 can be equal to each other. However, the present disclosure is not limited thereto.

[0361] In another embodiment, the third distance can be less than the first distance and / or the second distance. Since the third distance is less than the first distance and / or the second distance, the difference between the electromagnetic force generated in the X-axis direction and the electromagnetic force generated in the Y-axis direction can be further reduced compared to the case where the first distance to the third distance are equal to each other.

[0362] The height H3 of the dummy member 135 can be less than or equal to the height H2 of the third magnet 130-3. However, the present disclosure is not limited thereto. In another embodiment, the height H3 of the dummy member 135 can be greater than the height H2 of the third magnet 130-3.

[0363] Referring to Figure 10a , for example, the height of the upper surface of the dummy member 135 arranged at the housing 140 can be less than the height of the upper surface of the position sensor 170 and can be greater than the height of the lower surface of the position sensor 170. Alternatively, the height of the upper surface of the dummy member 135 can be less than or equal to the height of the lower surface of the position sensor 170.

[0364] For example, at the initial position of the bobbin 110, the height of the upper surface of the dummy member 135 arranged at the housing 140 can be less than the height of the upper surface of the sensing magnet 180 and can be greater than the height of the lower surface of the sensing magnet 180. Alternatively, at the initial position of the bobbin 110, the height of the upper surface of the dummy member 135 can be less than or equal to the height of the lower surface of the sensing magnet 180.

[0365] For example, the height of the upper surface of the dummy member 135 may be less than the height of the upper surface of the third magnet 130-3. However, this disclosure is not limited thereto. In another embodiment, the height of the upper surface of the dummy member 135 may be greater than or equal to the height of the upper surface of the third magnet 130-3.

[0366] The height of the lower surface of the dummy member 135 may be less than the height of the lower surface of the third magnet 130-3. However, this disclosure is not limited thereto. In another embodiment, the height of the lower surface of the dummy member 135 may be greater than or equal to the height of the lower surface of the third magnet 130-3.

[0367] Reference Figure 10c The height of the upper surface of the dummy member 135 may be less than the height of the upper surface of the second magnet 130-2 (or the first magnet 130-1). However, this disclosure is not limited thereto. In another embodiment, the height of the upper surface of the dummy member 135 may be greater than or equal to the height of the upper surface of the second magnet 130-2 (or the first magnet 130-1).

[0368] Furthermore, the height of the lower surface of the dummy member 135 may be less than the height of the lower surface of the second magnet 130-2 (or the first magnet 130-1). However, this disclosure is not limited thereto. In another embodiment, the height of the lower surface of the dummy member 135 may be greater than or equal to the height of the lower surface of the second magnet 130-2 (or the first magnet 130-1).

[0369] The implementation includes three magnets 130-1 to 130-3 and three coil units 230-1 to 230-3 corresponding to these magnets for OIS, in order to reduce magnetic field interference between magnets included in the adjacent lens moving device of a dual-camera module or more camera modules.

[0370] Two of the three magnets 130-1 to 130-3, 130-1 and 130-2, can perform AF operation based on their interaction with the first coil unit 120-1 and the second coil unit 120-2, and can simultaneously perform OIS operation in the Y-axis direction based on their interaction with the third coil unit 230-1 and the fourth coil unit 230-2.

[0371] Another magnet 130-3 of the three magnets 130-1 to 130-3 can perform OIS operation only in the X-axis direction based on its interaction with the fifth coil unit 230-3.

[0372] Since the dummy component 135 is arranged opposite to the third magnet 130-3, this embodiment can prevent oscillations caused by weight eccentricity during OIS operation.

[0373] Each of the first magnet 130-1 to the third magnet 130-3 can be a unipolar magnetized magnet having a single N pole and a single S pole. For example, each of the first magnet 130-1 and the second magnet 130-2 can be arranged such that the first surface of each of the two magnets opposite to the first coil 120 (or the outer surface of the winding frame 110) has an N pole, and the second surface of each of the two magnets opposite to the first surface has an S pole. However, this disclosure is not limited thereto. Each magnet can be arranged to have opposite poles. The positions of the S pole and N pole of the first magnet 130-1 and the second magnet 130-2 can be set such that an electromagnetic force is generated due to the interaction between the first magnet 130-1 and the second magnet 130-2, depending on the arrangement of the first coil 120.

[0374] Additionally, for example, the third magnet 130-3 can be arranged such that a first surface of the third magnet 130-3 opposite to the outer surface of the winding frame 110 has an N pole, and a second surface of the third magnet 130-3 opposite to the first surface has an S pole. However, this disclosure is not limited thereto. Magnets can be arranged to have opposite poles.

[0375] Alternatively, in another embodiment, each of the first magnet 130-1 to the third magnet 130-3 may be configured such that the N pole and the S pole are arranged in the direction of the optical axis.

[0376] Figure 15 A first magnet 130-1a, a second magnet 130-2a, and a third magnet 130-3a according to another embodiment are shown. Figure 15 and Figure 12 The same reference numerals in the accompanying drawings indicate the same parts, and descriptions of the same parts will be given briefly or omitted.

[0377] Reference Figure 15 The first magnet 130-1a may include a first magnet portion 11a, a second magnet portion 11b, and a first partition portion 11c disposed between the first magnet portion 11a and the second magnet portion 11b.

[0378] The second magnet 130-2a may include a third magnet portion 12a, a fourth magnet portion 12b, and a second partition portion 12c disposed between the third magnet portion 12a and the fourth magnet portion 12b.

[0379] The third magnet 130-3a may include a fifth magnet portion 13a, a sixth magnet portion 13b, and a third partition portion 13c disposed between the fifth magnet portion 13a and the sixth magnet portion 13b. Here, the first partition portion 11c may be referred to as the "first non-magnetic partition portion", the second partition portion 12c may be referred to as the "second non-magnetic partition portion", and the third partition portion 13c may be referred to as the "third non-magnetic partition portion".

[0380] For example, the first magnet portion 11a and the second magnet portion 11b may be spaced apart from each other in the optical axis direction, the third magnet portion 12a and the fourth magnet portion 12b may be spaced apart from each other in the optical axis direction, and the fifth magnet portion 13a and the sixth magnet portion 13b may be spaced apart from each other in the optical axis direction.

[0381] The first magnet portion 11a may include an N pole, a S pole, and a first boundary surface 21a between the N pole and the S pole, and the second magnet portion 11b may include an N pole, a S pole, and a second boundary surface 21b between the N pole and the S pole.

[0382] Additionally, each of the third magnet portion 12a and the fourth magnet portion 12b may include an N pole, a S pole, and a boundary surface between the N pole and the S pole. Furthermore, each of the fifth magnet portion 13a and the sixth magnet portion 13b may include an N pole, a S pole, and a boundary surface between the N pole and the S pole.

[0383] The first boundary surface 21a may be a substantially non-magnetic portion, may include portions with a small polarity, and may be a naturally occurring portion to form a magnet composed of N and S poles.

[0384] The first dividing portion 11c may be a portion that separates or isolates the first magnet portion 11a and the second magnet portion 11b from each other and is substantially non-magnetic, and may be a portion with a small polarity. For example, the first dividing portion 11c may be a non-magnetic material or air. This dividing portion may be referred to as a "neutral region".

[0385] The first partition 11c is an artificially formed portion when the first magnet portion 11a and the second magnet portion 11b are magnetized. The width W11 of the first partition 11c may be greater than the width of each of the first boundary surface 21a and the second boundary surface 21b.

[0386] Here, the width W11 of the first partition 11c can be the length of the non-magnetic partition 11c in the direction from the first magnet portion 11a to the second magnet portion 11b. Alternatively, the width W11 of the first partition 11c can be the length of the first partition 11c in the optical axis direction.

[0387] For example, the width W11 of the first partition 11c can be from 0.2 mm to 0.5 mm. Alternatively, the width W11 of the first partition 11c can be from 0.3 mm to 0.4 mm.

[0388] The first magnet portion 11a and the second magnet portion 11b can be arranged such that opposite poles are opposite to each other in the direction of the optical axis.

[0389] For example, the N pole of the first magnet portion 11a and the S pole of the second magnet portion 11b can be arranged opposite to the first coil unit 120-1. However, this disclosure is not limited thereto. The opposite arrangement is also possible.

[0390] The description of the boundary surface 21a of the first magnet portion 11a and the boundary surface 21b of the second magnet portion 11b can be applied to the boundary surfaces of each of the third to sixth magnet portions 12a, 12b, 13a and 13b. Additionally, the description of the first partition 11c can be applied to the second partition 12c and the third partition 13c.

[0391] Each of the first to third partitions 11c, 12c and 13c may extend in a horizontal direction or in a direction perpendicular to the optical axis.

[0392] The first magnet portion 11a, the first partition portion 11c, and the second magnet portion 11b can be arranged sequentially along the optical axis. The third magnet portion 12a, the second partition portion 12c, and the fourth magnet portion 12b can be arranged sequentially along the optical axis. In addition, the fifth magnet portion 13a, the third partition portion 13c, and the sixth magnet portion 13b can be arranged sequentially along the optical axis.

[0393] For example, the first magnet portion 11a can be arranged on the first partition portion 11c, and the second magnet portion 11b can be arranged below the first partition portion 11c. Additionally, the third magnet portion 12a can be arranged on the second partition portion 12c, and the fourth magnet portion 12b can be arranged below the second partition portion 12c. The fifth magnet portion 13a can be arranged on the third partition portion 13c, and the sixth magnet portion 13b can be arranged below the third partition portion 13c.

[0394] For example, each of the first to third partitions 11c, 12c and 13c may be parallel to a straight line perpendicular to the optical axis, and the boundary surface 21a or 21b of each of the first to sixth magnet portions 11a, 11b, 12a, 12b, 13a and 13b may be parallel to the optical axis.

[0395] For example, in each of the first magnet 130-1 to the third magnet 130-3, the N pole and S pole in the form of bipolar magnetization can be arranged in the direction of the optical axis.

[0396] The first magnet 130-1a can be positioned inside the region of the third coil unit 230-1 and can overlap with the third coil unit 230-1 in the optical axis direction.

[0397] The second magnet 130-2a can be positioned inside the region of the fourth coil unit 230-2 and can overlap with the fourth coil unit 230-2 in the optical axis direction.

[0398] The third magnet 130-3a can be positioned inside the region of the fifth coil unit 230-3 and can overlap with the fifth coil unit 230-3 in the optical axis direction.

[0399] A portion of the third coil unit 230-1 may simultaneously overlap with the first polarity portion of the first magnet portion 11a, the first separator 11c, and the second polarity portion of the second magnet portion 11b in the optical axis direction. Here, the first polarity portion may be an N pole or an S pole, and the second polarity portion may be a polarity portion having a polarity opposite to that of the first polarity portion.

[0400] A portion of the fourth coil unit 230-2 may simultaneously overlap with the first polar portion of the third magnet portion 12a, the second partition portion 12c, and the second polar portion of the fourth magnet portion 12b in the optical axis direction.

[0401] A portion of the fifth coil unit 230-3 may simultaneously overlap with the first polar portion of the fifth magnet portion 13a, the third partition portion 13c, and the second polar portion of the sixth magnet portion 13b in the optical axis direction.

[0402] In another embodiment, each of the first magnet and the second magnet can be Figure 12 A monopole magnetized magnet, and the third magnet can be Figure 15 A bipolar magnetized magnet.

[0403] Figure 16a A first magnet 130-1a, a second magnet 130-2a, and a third magnet 130-3b according to yet another embodiment are shown. Figure 16b Is Figure 16a Side view of the component shown. Figure 16c yes Figure 16a A plan view of the first magnet 130-1a, the second magnet 130-2a, the third magnet 130-3b, and the third coil units 230-1 to the fifth coil units 230-3. Figure 16d It includes Figure 16a A cross-sectional view of the lens moving device of the third magnet 130-3b in the CD direction, and Figure 16e It shows Figure 16a The magnetic field lines of the third magnet 130-3b relative to the fifth coil unit 230-3 and the magnetic field lines of the first magnet 130-1a relative to the third coil unit 230-1.

[0404] Figure 16a and Figure 15 The same reference numerals in the accompanying drawings indicate parts, and descriptions of the same parts will be given briefly or omitted.

[0405] Reference Figures 16a to 16e The third magnet 130-3b may include a fifth magnet portion 1013a, a sixth magnet portion 1013b, and a third partition portion 1013c disposed between the fifth magnet portion 1013a and the sixth magnet portion 1013b.

[0406] The definition of boundary surfaces 21a and 21b can apply to boundary surface 22a of the fifth magnet portion 1013a and boundary surface 22b of the sixth magnet portion 1013b. The third partition 1013c is an artificially formed portion when the fifth magnet portion 1013a and the sixth magnet portion 1013b are magnetized. The width W12 of the third partition 1013c can be greater than the width of each of the boundary surfaces 22a and 22b. Here, the width W12 of the third partition 1013c can be the length of the third partition 1013c in the direction from the fifth magnet portion 1013a to the sixth magnet portion 1013b.

[0407] For example, the width W12 of the third partition 1013c can be 0.2 mm to 0.5 mm. Alternatively, the width W12 of the third partition 1013c can be 0.3 mm to 0.4 mm.

[0408] The fifth magnet portion 1013a and the sixth magnet portion 1013b can be arranged such that opposite magnetic poles are opposite each other in a direction perpendicular to the optical axis OA and face the third magnet 130-3b from the optical axis OA.

[0409] For example, the N and S poles of the sixth magnet portion 1013b can be arranged opposite to the outer surface of the third side portion 141-3 of the winding frame 110 corresponding to the housing 140. However, this disclosure is not limited thereto. The opposite arrangement is possible.

[0410] The third partition 1013c can extend in the optical axis direction or the vertical direction.

[0411] The fifth magnet portion 1013a, the third partition portion 1013c, and the sixth magnet portion 1013b can be arranged sequentially in a direction perpendicular to the optical axis OA and in a direction from the third magnet 130-3b to the optical axis OA.

[0412] For example, the fifth magnet portion 1013a may be arranged to the left (or right) of the third partition portion 1013c, and the sixth magnet portion 1013b may be arranged to the right (or left) of the third partition portion 1013c.

[0413] For example, the third partition 1013c may be parallel to the optical axis, and the boundary surface 22a of the fifth magnet portion 1013a and the boundary surface 22b of the sixth magnet portion 1013b may be parallel to the direction perpendicular to the optical axis.

[0414] The separation or isolation direction of the third partition 1013c may be perpendicular to the separation or isolation direction of each of the first partition 1011c and the second partition 1012c.

[0415] The length W21 of the third magnet 130-3b in the width direction can be greater than the length W1 of the first magnet 130-1a in the width direction and / or the length of the second magnet 130-2 in the width direction (W21>W1). Since W21>W1, this embodiment can reduce the difference between the first electromagnetic force in the X-axis direction and the sum of the second and third electromagnetic forces in the Y-axis direction, thereby improving the reliability in OIS operation.

[0416] The height H21 of the third magnet 130-3b can be less than the height H1 of the first magnet 130-1a and / or the height H21 of the second magnet 130-2a.

[0417] That is, the length of the third magnet 130-3b in the optical axis direction can be less than the length of the first magnet 130-1a in the optical axis direction and / or the length of the second magnet 130-2a in the optical axis direction.

[0418] According to Figure 16e The direction of the magnetic field lines of the third magnet 130-3b shown remains unchanged even if the height H21 of the third magnet 130-3b decreases (e.g., H21).

[0419] ​​Since H21 < H1, this embodiment can reduce the weight of the lens moving device, thereby reducing the power consumption for AF driving and / or OIS driving. In another embodiment, H21 = H1.

[0420] In addition, for example, the height of the upper surface of the third magnet 130-3b may be greater than or equal to the height of the boundary line between the second magnet portion 11b and the first partition portion 11c of the first magnet 130-1a, and may be less than or equal to the height of the upper surface of the first magnet portion 11a.

[0421] In addition, for example, H21:H1 = 0.3:1 to 1:1. When H21 / H1 is less than 0.3, the first electromagnetic force generated by the fifth coil unit 230-3 and the third magnet 130-3b may be excessively reduced, whereby the difference between the electromagnetic force in the X-axis direction and the electromagnetic force in the Y-axis direction may increase, and thus the reliability in OIS driving may decrease.

[0422] When H21 / H1 is greater than 1, the first electromagnetic force in the X-axis direction may increase, whereby the difference between the electromagnetic force in the X-axis direction and the electromagnetic force in the Y-axis direction may increase, and thus the reliability of OIS driving may decrease.

[0423] Alternatively, for example, H21:H1 = 0.5:1 to 0.8:1.

[0424] Referring to 16C, each of the third coil unit 230-1 to the fifth coil unit 230-3 may have an annular shape including a hole that is open in the optical axis direction.

[0425] The length R1 of the hole of the fifth coil unit 230-3 in the direction perpendicular to the longitudinal direction of the fifth coil unit 230-3 may be less than the length R2 (R1 < R2) of the hole of the second coil unit 230-3 in the direction perpendicular to the longitudinal direction of the third coil unit 230-1. In addition, R1 may be less than the length of the hole of the fourth coil unit 230-2 in the direction perpendicular to the longitudinal direction of the fourth coil unit 230-2.

[0426] Since the first magnet 130-1a and the third magnet 130-3b are different from each other in the magnetization direction, the two have different distributions on the magnetic lines of force. When R2 > R1 is set in consideration of the different distributions on the magnetic lines of force, the electromagnetic force between the first magnet 130-1a and the third coil unit 230-1, the electromagnetic force between the second magnet 130-2a and the fourth coil unit 230-2, and the electromagnetic force between the third magnet 130-3b and the fifth coil unit 230-3 can be increased.

[0427] In addition, the number of coil windings at the fifth coil unit 230-3 (hereinafter referred to as the "first winding number") can be greater than the number of coil windings at the third coil unit 230-1 (hereinafter referred to as the "second winding number") and / or the number of coil windings at the fourth coil unit 230-2 (hereinafter referred to as the "third winding number"), thereby reducing the difference between the electromagnetic force in the X-axis direction and the electromagnetic force in the Y-axis direction.

[0428] Alternatively, for example, the number of second windings and the number of third windings may be equal to each other. However, this disclosure is not limited thereto. In another embodiment, the number of first windings and the number of second windings (or the number of third windings) may be equal to each other.

[0429] Reference Figure 16d The height of the upper surface of the dummy member 135 may be greater than or equal to the height of the upper surface of the third magnet 130-3b. However, this disclosure is not limited thereto. In another embodiment, the height of the upper surface of the dummy member 135 may be less than the height of the upper surface of the third magnet 130-3b.

[0430] The height of the lower surface of the dummy member 135 may be less than the height of the lower surface of the third magnet 130-3b. However, this disclosure is not limited thereto. In another embodiment, the height of the lower surface of the dummy member 135 may be greater than the height of the lower surface of the third magnet 130-3b.

[0431] In addition, the height of the upper surface of the dummy component 135 can be less than the height of the upper surface of the second magnet 130-2a (or the first magnet 130-1a), and can be greater than the height of the lower surface of the second magnet 130-2a (or the first magnet 130-1a).

[0432] Furthermore, the height of the lower surface of the dummy member 135 may be less than the height of the lower surface of the second magnet 130-2a (or the first magnet 130-1a). However, this disclosure is not limited thereto. In another embodiment, the height of the lower surface of the dummy member 135 may be greater than the height of the lower surface of the second magnet 130-2a (or the first magnet 130-1a).

[0433] The implementation includes three magnets 130-1a, 130-2a and 130-3b and three coil units 230-1 to 230-3 corresponding to these magnets for OIS, in order to reduce magnetic field interference between magnets included in the adjacent lens moving device of a dual-camera module or more camera modules.

[0434] Each of the first magnet 130-1a and the second magnet 130-2a may have a magnetization direction in which two magnet portions 11a and 11b are arranged above and below the partition 11c, or two magnet portions 12a and 12b are arranged above and below the partition 12c. Furthermore, the first portion 3a and the second portion 3b of each of the first coil unit 120-1 and the second coil unit 120-2 may be arranged opposite to the two magnet portions 11a and 11b or the two magnet portions 12a and 12b. In this arrangement, the electromagnetic force between the first magnet 130-1a and the first coil unit 120-1, and the electromagnetic force between the second magnet 130-2a and the second coil unit 120-2, can be increased, thereby reducing current consumption.

[0435] Typically, the electromagnetic force in the X-axis direction resulting from the interaction between one magnet and one coil unit is less than the electromagnetic force in the Y-axis direction resulting from the interaction between two magnets and two coil units. The difference between the electromagnetic forces in the X-axis and Y-axis directions can cause malfunctions in the OIS drive.

[0436] The implementation can be constructed as follows to reduce the difference between the electromagnetic force in the X-axis direction and the electromagnetic force in the Y-axis direction.

[0437] The magnetization directions of the two magnetic portions 1013a and 1013b of the third magnet 130-3b are formed to be perpendicular to the magnetization directions of the two magnetic portions 11a and 11b or the two magnetic portions 12a and 12b of each of the first magnet 130-1a and the second magnet 130-2a.

[0438] For example, the third magnet 130-3b can be arranged on the fifth coil unit 230-3 such that the third partition 1013c, which separates the two magnet parts 1013a and 1013b of the third magnet 130-3b from each other, is perpendicular to the fifth coil unit 230-3.

[0439] For example, the third magnet 130-3b can be arranged such that the third partition 1013c is parallel to the optical axis.

[0440] Alternatively, for example, the third magnet 130-3b can be arranged such that the N pole of one of the two magnet portions 1013a and 1013b of the third magnet 130-3b and the S pole of the other magnet are opposite to the fifth coil unit 230-3 in the optical axis direction.

[0441] On the other hand, the first magnet 130-1a can be arranged on the third coil unit 230-1 such that the first dividing portion 11c is parallel to the third coil unit 230-1, and the second magnet 130-2a can be arranged on the fourth coil unit 230-2 such that the second dividing portion 12c is parallel to the fourth coil unit 230-2.

[0442] Alternatively, for example, the first magnet 130-1a and the second magnet 130-2a can be arranged such that the first partition 11c and the second partition 12c are parallel to the optical axis direction.

[0443] Alternatively, for example, the N pole and S pole of one of the two magnetic portions 11a and 11b of the first magnet 130-1a may both be opposite to the third coil unit 230-1 in the optical axis direction, and the N pole and S pole of one of the two magnetic portions 12a and 12b of the second magnet 130-2a may both be opposite to the fourth coil unit 230-2 in the optical axis direction.

[0444] Furthermore, the length L2 of the third magnet 130-3b can be greater than the length L1 of the first magnet 130-1a and / or the length of the second magnet 130-2a, and the length M2 of the fifth coil unit 230-3 in the longitudinal direction can be greater than the length M1 of the third coil unit 230-1 and / or the length of the fourth coil unit 230-2. Therefore, the difference between the electromagnetic force in the X-axis direction and the electromagnetic force in the Y-axis direction can be reduced.

[0445] Reference Figure 16d The magnetic field lines of the third magnet 130-3b relative to the fifth coil unit 230-3 are different in direction from the magnetic field lines of the first magnet 130-1a relative to the third coil unit 230-1.

[0446] Since the arrangement of the second magnet 130-2a is the same as or similar to that of the first magnet 130-1a, the magnetic field lines of the second magnet 130-2a relative to the fourth coil unit 230-2 can be the same as or similar to the magnetic field lines of the first magnet 130-1a relative to the third coil unit 230-1.

[0447] The first electromagnetic force generated by the magnetic field lines MF2 of the fifth coil unit 230-3 and the third magnet 130-3b can be greater than the second electromagnetic force generated by the magnetic field lines MF1 of the third coil unit 230-1 and the first magnet 130-1a.

[0448] Furthermore, the first electromagnetic force generated by the magnetic field lines MF2 of the fifth coil unit 230-3 and the third magnet 130-3b can be greater than the third electromagnetic force generated by the magnetic field lines MF1 of the fourth coil unit 230-2 and the second magnet 130-2a.

[0449] Since the first electromagnetic force is greater than each of the second and third electromagnetic forces, it can be designed such that the sum of the second and third electromagnetic forces is almost equal to the first electromagnetic force. Therefore, this embodiment can reduce the difference between the electromagnetic force in the X-axis direction and the electromagnetic force in the Y-axis direction during OIS driving.

[0450] Figure 16f It shows that due to Figure 16a The simulation results show the electromagnetic force Fy in the Y-axis direction caused by the interaction between the first magnet 130-1 and the second magnet 130-2a and the third coil unit 230-1 and the fourth coil unit 230-2, and the electromagnetic force Fx in the X-axis direction caused by the interaction between the third magnet 130-3b and the fifth coil unit 230-3. Figure 16f The linearity in the X-axis direction and the linearity in the Y-axis direction are also shown.

[0451] exist Figure 16f In this configuration, the resistance of each of the third coil unit 230-1 to the fifth coil unit 230-3 can be from 6 ohms to 8 ohms. Each of the first magnet 130-1a to the third magnet 130-3b can be an N45H or N45SH magnet to an N50H or N50SH magnet. Figure 16f In the simulation, each of the first magnet 130-1a to the third magnet 130-3b is an N48H magnet.

[0452] Reference Figure 16f The ratio of Fx to Fy (Fx / Fy) is 0.88:1. That is, it can be seen that the deviation between Fx and Fy is less than 12%. Based on the simulation results, this implementation can reduce the difference between the electromagnetic force in the X-axis direction and the electromagnetic force in the Y-axis direction when OIS is driven, thereby ensuring reliability in OIS driving.

[0453] Furthermore, when each of the travel in the X-axis direction and the travel in the Y-axis direction has a range of -150 μm to 150 μm, a linearity of 10 nm or less in each of the linearities in the X-axis and Y-axis directions is satisfactory. The linearity in the X-axis direction can represent the deviation between the trend line of travel in the X-axis direction and the travel in the X-axis direction. The linearity in the Y-axis direction can represent the deviation between the trend line of travel in the Y-axis direction and the travel in the Y-axis direction. In the simulation, the trend line of travel in the X-axis direction is y = 0.0015x + 0.003, and the trend line of travel in the Y-axis direction is y = 0.0018x - 7E - 0.6. It is assumed that the stiffness of each of the upper elastic member 150 and the lower elastic member 160 is 70 mN / mm, and the weight of the lens mounted in the winding frame 110 is 150 mg.

[0454] Furthermore, the lens moving device 100 according to the above embodiment may further include a lens and / or lens barrel mounted in the winding frame 110. Additionally, the lens moving device 100 according to the embodiment may also include an image sensor. Furthermore, the lens moving device 100 may also include a circuit board on which the image sensor is mounted. Additionally, the lens moving device 100 may also include a filter configured to filter light passing through the lens and provide the filtered light to the image sensor. Furthermore, the lens moving device 100 may also include a motion sensor or a controller.

[0455] Figure 17a yes Figure 11 A cross-sectional view of the first dashed portion 60A of the third coil unit 230-1. Figure 17b The first path 55a and the second path 55b of the third coil unit 230-1 are shown. Figure 18a yes Figure 11 The cross-sectional view of the second dashed portion 60B of the fifth coil unit 230-3, and Figure 18b The first passage 56a and the second passage 56b of the fifth coil unit 230-3 are shown. The description of the third coil unit 230-1 in Figure 17 can be applied to the structure and shape of the fourth coil unit 230-2.

[0456] Reference Figure 11 and Figures 17a to 18b The second coil 230 may be formed on the substrate 231, and the substrate 231 may include a first side portion 23a and a second side portion 23b opposite to each other, a third side portion 23c and a fourth side portion 23d opposite to each other, and an opening 231a.

[0457] The third coil unit 230-1 can be arranged in a first region Re1 located between the first side 23a of the circuit member 231 and the opening 231a of the circuit member 231, and can have a first number of turns (or a first number of windings).

[0458] The fourth coil unit 230-2 can be arranged in the second region Re2 located between the second side 23b of the circuit member 231 and the opening 231a of the circuit member 231, and can have a second number of turns (or a second number of windings).

[0459] The fifth coil unit 230-3 can be arranged in the third region Re3 located between the third side 23b of the circuit member 231 and the opening 231a of the circuit member 231, and can have a third number of turns (or a third number of windings). Here, each of the first side 23a to the fourth side 23d of the circuit member 231 can correspond to one of the first side portions 141-1 to the fourth side portions 141-4 of the housing 140.

[0460] Reference Figure 17a The third coil unit 230-1 may include a first wire having multiple turns.

[0461] The third coil unit 230-1 may have a first pattern PA1 comprising a continuous spiral, an ellipse, and / or a track shape.

[0462] The fourth coil unit 230-2 may have the same shape as the third coil unit 230-1. That is, the fourth coil unit 230-2 may include a second wire with multiple turns.

[0463] For example, the fourth coil unit 230-2 may have a second pattern that includes a continuous spiral and / or track shape. For example, the second pattern may be the same as the first pattern PA1.

[0464] Reference Figure 18a The fifth coil unit 230-3 may include a third wire with multiple turns.

[0465] For example, the fifth coil unit 230-3 may have a third pattern PA2 that includes a continuous spiral and / or track shape.

[0466] A first pattern PA1 can be formed in the first region Re1 of the substrate 231, a second pattern can be formed in the second region Re2 of the substrate 231, and a third pattern PA2 can be formed in the third region Re3 of the substrate 231.

[0467] For example, each of the first pattern PA1 to the third pattern PA2 may be made of a conductor. For example, each of the first pattern PA1 to the third pattern PA2 may be made of a conductive metal, such as copper, gold, aluminum, silver, or an alloy including at least one of them.

[0468] The width A2 of the third wire of the fifth coil unit 230-3 is smaller than the width A1 of the first wire of the third coil unit 230-1 and the width A1 of the second wire of the fourth coil unit 230-2.

[0469] For example, the width A2 (or line width) of the third pattern PA2 of the fifth coil unit 230-3 is smaller than the width A1 (or line width) of the first pattern PA1 of the third coil unit 230-2 and the width A1 (or line width) of the second pattern of the fourth coil unit 230-1 (A2). <A1)。

[0470] Here, the width of each of the first pattern PA1 to the third pattern PA2 can be the length of each of the first pattern PA1 to the third pattern PA2 in the width direction perpendicular to its longitudinal direction.

[0471] The width of the first line of the third coil unit 230-1 and the width of the second line of the fourth coil unit 230-2 can be equal to each other. For example, the width A1 of the first pattern PA1 of the third coil unit 230-1 can be equal to the width of the second pattern of the fourth coil unit 230-2.

[0472] The ratio of A2 to A1 (A2:A1) can be from 1:1.2 to 1:2.

[0473] When the value obtained by dividing A1 by A2 (A1 / A2) is less than 1.2, the difference between the number of turns of the fifth coil unit 230-3 and the number of turns of the third coil unit 230-1 (or the fourth coil unit 230-2) decreases, making it impossible to reduce the difference between the electromagnetic force in the Y-axis direction and the electromagnetic force in the X-axis direction. The electromagnetic force in the Y-axis direction is generated by the interaction between the first magnet 130-1 and the second magnet 130-2 and the third coil unit 230-1 and the fourth coil unit 230-2, while the electromagnetic force in the X-axis direction is generated by the interaction between the third magnet 130-3 and the fifth coil unit 230-3. Therefore, the reliability in OIS driving may be reduced.

[0474] If the value obtained by dividing A1 by A2 (A1 / A2) is greater than 2, the resistance of the fifth coil unit 230-3 may increase, thereby increasing the power consumption, or the magnitude of the drive signal of the fifth coil unit 230-3 may increase.

[0475] For example, the ratio of A2 to A1 (A2:A1) can be from 1:1.25 to 1:1.5.

[0476] For example, the width A1 of each of the first and second patterns PA1 can be 24 μm to 30 μm, and the width A2 of the third pattern PA2 can be 15 μm to 20 μm.

[0477] The height (or thickness) of the third coil unit 230-1 and the height (or thickness) of the fourth coil unit 230-2 can be equal to each other. For example, the height of the first pattern PA1 and the height T1 of the second pattern can be equal to each other.

[0478] Additionally, the height T2 (or thickness) of the third pattern PA2 can be equal to the height T1 (or thickness) of each of the first and second patterns PA1 (T2 = T1). For example, T2 = T1 = 45 μm to 50 μm. Here, T1 can be the length of each of the first and second patterns PA1 in the optical axis direction, and T2 can be the length of the third pattern PA2 in the optical axis direction.

[0479] The width of each of the wires in the third coil unit 230-1 to the fifth coil unit 230-3 may be less than the height (or thickness) of each of the third coil unit 230-1 to the fifth coil unit 230-3.

[0480] The widths A1 and A2 of the first pattern PA1 to the third pattern PA2 can be smaller than the heights T1 and T2 (or thicknesses) (A1, A2) of the first pattern PA1 to the third pattern PA2. <T1,T2)。

[0481] Figures 17 and 18 show that each of the third coil unit 230-1 to the fifth coil unit 230-3 has a double-layer structure. However, this disclosure is not limited thereto. In another embodiment, each of the third coil unit 230-1 to the fifth coil unit 230-3 may have a single-layer structure or a three-layer or more-layer structure.

[0482] For example, each of the first pattern PA1 of the third coil unit 230-1 and the second pattern of the fourth coil unit 230-2 can be a spiral pattern with a first number of turns.

[0483] Each of the third coil unit 230-1 to the fifth coil unit 230-3 may include a first layer 11 or layer 21 and a second layer 12 or layer 22 arranged on the first layer 11 or layer 21.

[0484] For example, each of the first and second patterns PA1 may include a first layer 11 having a continuous spiral, elliptical, and / or track shape and a second layer 12 arranged on the first layer 11, the second layer having a continuous spiral, elliptical, and / or track shape.

[0485] Alternatively, for example, the third pattern PA2 of the fifth coil unit 230-3 can be a spiral pattern with a second number of turns that is greater than the first number of turns.

[0486] For example, the third pattern PA2 may include a first layer 21 having a continuous spiral, elliptical and / or track shape and a second layer 22 arranged on the first layer 21, the second layer having a continuous spiral, elliptical and / or track shape.

[0487] The width of the third line of each of the first layer 21 and the second layer 22 of the fifth coil unit 230-3 may be smaller than the width of the first line of each of the first and second layers of the third coil unit 230-1 and the width of the second line of each of the first and second layers of the fourth coil unit 230-2.

[0488] The width A2 of each of the first layer 21 and the second layer 22 of the third pattern PA2 is less than the width of each of the first layer 11 and the second layer 12 of each of the first and second patterns PA1.

[0489] The third coil unit 230-1 may include multiple lines arranged in the first region Re1 in the direction from the first side 23a to the second side 23b or in the direction from the third coil unit 230-1 to the fourth coil unit 230-2.

[0490] The first layer 11 of the first pattern PA1 may include multiple first lines R1 to Rn arranged in the first region Re1 in the direction from the first side 23a to the second side 23b or in the direction from the third coil unit 230-1 to the fourth coil unit 230-2.

[0491] Additionally, the second layer 12 of the first pattern PA1 may include multiple second lines Q1 to Qn arranged in the first region Re1 in the direction from the first side 23a to the second side 23b or in the direction from the third coil unit 230-1 to the fourth coil unit 230-2.

[0492] The fourth coil unit 230-2 may include multiple lines arranged in the first region Re1 in the direction from the first side 23a to the second side 23b or in the direction from the third coil unit 230-1 to the fourth coil unit 230-2.

[0493] The first and second layers of the second pattern may include multiple lines (e.g., R1 to Rn and Q1 to Qn) arranged in the second region Re2 in the direction from the first side 23a to the second side 23b of the substrate 231 or in the direction from the third coil unit 230-1 to the fourth coil unit 230-2.

[0494] The fifth coil unit 230-3 may include multiple lines arranged in the third region Re3 in the direction from the third side 23c to the fourth side 23d or in the direction perpendicular to the direction from the third coil unit 230-1 to the fourth coil unit 230-2.

[0495] Additionally, the first layer 21 of the third pattern PA2 may include multiple first lines S1 to Sm arranged in the third region Re3 in the direction from the third side 23c to the fourth side 23d or in the direction perpendicular to the direction from the third coil unit 230-1 to the fourth coil unit 230-2.

[0496] The second layer La22 of the third pattern PA2 may include multiple second lines P1 to Pm arranged in the third region Re3 in the direction from the third side 23c to the fourth side 23d or in the direction perpendicular to the direction from the third coil unit 230-1 to the fourth coil unit 230-2. The "line" may be referred to as a "conductive line" or a "coil pattern line".

[0497] For example, the second lines Q1 to Qn or the second lines P1 to Pm of each of the first patterns PA1 to the third patterns PA2 can be arranged on the first lines R1 to Rn or the first lines S1 to Sm.

[0498] The width of each of the first lines R1 to Rn and the first lines S1 to Sm can be greater than the distance between the first lines R1 to Rn and the first lines S1 to Sm, and the width of each of the second lines Q1 to Qn and the second lines P1 to Pm can be greater than the distance between the second lines Q1 to Qn and the second lines P1 to Pm.

[0499] For example, the width of each of the first lines R1 to Rn and the first lines S1 to Sm can be greater than the shortest distance between the first lines R1 to Rn and the first lines S1 to Sm, and the width of each of the second lines Q1 to Qn and the second lines P1 to Pm can be greater than the shortest distance between the second lines Q1 to Qn and the second lines P1 to Pm.

[0500] For example, the number of the first lines R1 to Rn (n>1, n is a natural number) and the number of the second lines Q1 to Qn (n>1, n is a natural number) in each of the first and second patterns PA1 can be equal to each other.

[0501] In addition, for example, the first lines R1 to Rn (n>1, n is a natural number) and the second lines Q1 to Qn (n>1, n is a natural number) can be aligned with each other in the optical axis direction or can overlap with each other. However, the present disclosure is not limited thereto.

[0502] For example, the number of the first lines S1 to Sm (m>n>1, m is a natural number) and the number of the second lines P1 to Pm (m>n>1, m is a natural number) in the third pattern PA2 can be equal to each other. In addition, for example, the first lines S1 to Sm (m>n>1, m is a natural number) and the second lines P1 to Pm (m>n>1, m is a natural number) in the third pattern PA2 can be aligned with each other in the optical axis direction or can overlap with each other. However, the present disclosure is not limited thereto.

[0503] The distance B1 between the first lines R1 to Rn in each of the first and second patterns PA1 is less than the width A1 of each of the first lines R1 to Rn (B1<A1). In addition, the distance B1 between the second lines Q1 to Qn in each of the first and second patterns PA1 is less than the width A1 of each of the second lines Q1 to Qn (B1<A1).

[0504] The distance B1 between the first lines S1 to Sm in the third pattern PA2 is less than the width A2 of each of the first lines S1 to Sm (B1<A2). In addition, the distance B1 between the second lines P1 to Pm is less than the width A2 of each of the second lines P1 to Pm (B1<A2). For example, B1 can be 10 μm to 13 μm.

[0505] The width of each of the first lines R1 to Rn and the width of each of the second lines Q1 to Qn in each of the first and second patterns PA1 can be equal to each other. However, the present disclosure is not limited thereto. In another embodiment, the width of each of the first lines R1 to Rn and the width of each of the second lines Q1 to Qn can be different from each other.

[0506] The width of each of the first lines S1 to Sm and the width of each of the second lines P1 to Pm in the third pattern PA2 can be equal to each other. However, the present disclosure is not limited thereto. In another embodiment, the width of each of the first lines S1 to Sm and the width of each of the second lines P1 to Pm can be different from each other.

[0507] The width of each of the first lines S1 to Sm of the third pattern PA2 may be less than the width of each of the first lines R1 to Rn and the width of each of the second lines Q1 to Qn of the first and second patterns PA1.

[0508] The width of each of the second lines P1 to Pm of the third pattern PA2 may be less than the width of each of the first lines R1 to Rn and the width of each of the second lines Q1 to Qn of each of the first and second patterns PA1.

[0509] For example, the first length d1 of the first pattern PA1 (or second pattern) of the third coil unit 230-1 (or the fourth coil unit 230-2) in the width direction may be equal to the second length d2 of the third pattern PA2 of the fifth coil unit 230-2 in the width direction. However, this disclosure is not limited thereto.

[0510] d1 can be the distance between the opposite outermost ends of each of the third coil unit 230-1 and the fourth coil unit 230-2, and d2 can be the distance between the opposite outermost ends of the fifth coil unit 230-3. For example, d1 can be the length of the central portion of each of the third coil unit 230-1 and the fourth coil unit 230-2, and d2 can be the length of the central portion of the fifth coil unit 230-3. d1 and d2 can be the lengths of the third coil unit 230-1 to the fifth coil unit 230-3 in the width direction. Alternatively, for example, d1 and d2 can be the lengths in the direction from the sides 23a, 23b, and 23c of the circuit member 231 where the first and second coil units are arranged to the opening 231a.

[0511] For example, the first length can be the distance between the opposite outermost ends of the spiral patterns of each of the first and second patterns PA1, and the second length can be the distance between the opposite outermost ends of the spiral patterns of the third pattern PA2.

[0512] For example, d1 could be Figure 17a The distance between the opposite outermost ends of the outermost lines Rn or Qn in the first line R1 to Rn (or the second line Q1 to Qn). Alternatively, for example, d2 could be... Figure 18a The distance between the opposite outermost ends of the outermost lines Sm or Pm in the first line S1 to Sm (or the second line P1 to Pm).

[0513] In another embodiment, the width d2 of the fifth coil unit 230-3 may be greater than the width d1 of the third coil unit 230-1 (or the fourth coil unit 230-2). For example, the second length d2 of the third pattern PA2 in the width direction may be greater than the first length d1 of the first pattern PA1 (or the second pattern) in the width direction.

[0514] In another embodiment, the width d2 of the fifth coil unit 230-3 may be smaller than the width d1 of the third coil unit 230-1 (or the fourth coil unit 230-2). For example, the second length d2 of the third pattern PA2 in the width direction may be smaller than the first length d1 of the first pattern PA1 (or the second pattern) in the width direction.

[0515] For example, the second coil 230 may include a first dielectric layer 71, a first layer 11 and a second layer 21 arranged on the first dielectric layer 71 for the third coil units 230-1 to the fifth coil units 230-3, a second dielectric layer 73 arranged on the first layer 11 and a second layer 21, a second layer 12 and a second layer 22 arranged on the second dielectric layer 73, and a third dielectric layer 75 arranged on the second layer 12 and a third layer 22.

[0516] Each of the first dielectric layer 71 and the third dielectric layer 75 may include a polymeric organic compound or a resin. For example, each of the first dielectric layer 71 and the third dielectric layer 75 may include polyimide and a solder resist.

[0517] The second dielectric layer 73 may include a polymeric organic compound or a resin. For example, the second dielectric layer 73 may include polyimide and epoxy bonds.

[0518] The fourth dielectric layer 72 may be disposed between the first lines R1 to Rn or the first lines S1 to Sm of each of the first patterns PA1 to the third patterns PA2, and the fifth dielectric layer 74 may be disposed between the second lines Q1 to Qn or the second lines P1 to Pm of each of the first patterns PA1 to the third patterns PA2.

[0519] Each of the third coil units 230-1 to the fifth coil units 230-3 may include at least one path 55a and 55b or 56a and 56b, the paths 55a and 55b being configured to interconnect the first layer 11 and the second layer 12, and the paths 56a and 56b being configured to interconnect the first layer 21 and the second layer 22, the first layer 11 or the second layer 22 and the second layer 12 or the second layer 22 may be interconnected with each other (e.g., in parallel) through at least one path 55a and 55b or 56a and 56b.

[0520] Each of the third coil unit 230-1 and the fourth coil unit 230-2 may have a first passage 55a configured to connect one end of one of the first wires R1 to Rn (e.g., R1) to one end of one of the second wires Q1 to Qn (e.g., Q1).

[0521] Additionally, each of the third coil unit 230-1 and the fourth coil unit 230-2 may have a second passage 55b configured to connect one end of the other of the first wires R1 to Rn (e.g., Rn) and one end of the other of the second wires Q1 to Qn (e.g., Qn).

[0522] The first passage 55a and the second passage 55b of each of the third coil unit 230-1 and the fourth coil unit 230-2 may pass through or penetrate the dielectric layer 73. However, this disclosure is not limited thereto.

[0523] The first passage 55a and the second passage 55b of each of the third coil unit 230-1 and the fourth coil unit 230-2 can connect the first wires R1 to Rn and the second wires Q1 to Qn to each other. Here, "passage" can be referred to as "contact", "connecting electrode" or "connecting pattern".

[0524] Additionally, the fifth coil unit 230-3 may have a first passage 56a configured to connect one end of one of the first wires S1 to Sm (e.g., S1) and one end of one of the second wires P1 to Pm (e.g., P1).

[0525] Additionally, the fifth coil unit 230-3 may have a second passage 56b configured to connect one end of the other of the first wires S1 to Sm (e.g., Sm) and one end of the other of the second wires P1 to Pm (e.g., Pm).

[0526] The first passage 55a and the second passage 55b of the fifth coil unit 230-3 can pass through or penetrate the dielectric layer 73. However, this disclosure is not limited thereto. The first passage and the second passage of the fifth coil unit 230-3 can interconnect the first wires S1 to Sm and the second wires P1 to Pm.

[0527] A portion of each of the first pattern PA1 to the third pattern PA2 may be opened or exposed from at least one of the first dielectric layer 71 and the third dielectric layer 75, and the exposed portion may be connected to a corresponding terminal of the circuit board 250.

[0528] For example, a portion of the first layer 11 or layer 21 of each of the first patterns PA1 to the third patterns PA2 may be opened or exposed from the third dielectric layer 75, and the exposed portion may be connected to a corresponding terminal of the circuit board 250.

[0529] For example, a portion of the first layer 11 of each of the first and second patterns PA1 and a portion of the first layer 21 of the third pattern PA2 can be opened or exposed from the third dielectric layer 75, and the exposed portion can be connected to the corresponding terminal of the circuit board 250.

[0530] Since the width A2 of each of the first lines S1 to Sm and the second lines P1 to Pm of the fifth coil unit 230-3 is smaller than the width A1 of each of the first lines R1 to Rn and the second lines Q1 to Qn of the third coil unit 230-1 (or the fourth coil unit 230-2), the number of turns (or windings) of the fifth coil unit 230-3 can be greater than the number of turns (or windings) of each of the third coil unit 230-1 and the fourth coil unit 230-2 when the third coil unit 230-1 to the fifth coil unit 230-3 are formed in the same space. Therefore, the difference between the electromagnetic force generated in the X-axis direction and the electromagnetic force generated in the Y-axis direction can be reduced.

[0531] For example, the ratio of the number of turns (“first number of turns”) of each of the third coil unit 230-1 and the fourth coil unit 230-2 to the number of turns (“second number of turns”) of the fifth coil unit 230-3 can be from 1:1.1 to 1:2. However, this disclosure is not limited thereto.

[0532] If the value obtained by dividing the second number of turns by the first number of turns is less than 1.1, it is impossible to reduce the difference between the electromagnetic force in the Y-axis direction and the electromagnetic force in the X-axis direction, which may reduce the reliability of the OIS drive.

[0533] If the value obtained by dividing the second number of turns by the first number of turns is greater than 2, the resistance of the fifth coil unit 230-3 may increase, thereby increasing the power consumption, or the magnitude of the drive signal of the fifth coil unit 230-3 may increase.

[0534] For example, the ratio of the number of turns in each of the third coil unit 230-1 and the fourth coil unit 230-2 to the number of turns in the fifth coil unit 230-3 can be from 1:1.1 to 1:1.5. For example, the number of turns in each of the third coil unit 230-1 and the fourth coil unit 230-2 can be 30, and the number of turns in the fifth coil unit 230-3 can be 34. However, this disclosure is not limited thereto.

[0535] Furthermore, since the number of turns of the fifth coil unit 230-3 is greater than the number of turns of each of the third coil unit 230-1 and the fourth coil unit 230-2, the first electromagnetic force generated by the fifth coil unit 230-3 and the third magnet 130-3 can be greater than the second electromagnetic force generated by the third coil unit 230-1 and the first magnet 130-1, and can also be greater than the third electromagnetic force generated by the fourth coil unit 230-2 and the second magnet 130-2. Therefore, this embodiment can reduce the difference between the first electromagnetic force in the X-axis direction and the sum of the second and third electromagnetic forces in the Y-axis direction, thereby improving the reliability of OIS operation.

[0536] Each of the third coil unit 230-1 and the fourth coil unit 230-2 may include a first straight portion, a second straight portion, a first curved portion, and a second curved portion, wherein the first curved portion is configured to connect one end of each straight portion of the first straight portion and one end of a corresponding straight portion of the second straight portion to each other, and the second curved portion is configured to connect the other end of each straight portion of the first straight portion to the other end of a corresponding straight portion of the second straight portion.

[0537] The fifth coil unit 230-3 may include a third straight portion, a fourth straight portion, a third curved portion, and a fourth curved portion. The third curved portion is configured to connect one end of each straight portion in the third straight portion to one end of a corresponding straight portion in the fourth straight portion. The fourth curved portion is configured to connect the other end of each straight portion in the third straight portion to the other end of a corresponding straight portion in the fourth straight portion.

[0538] The width of each straight segment in the first straight section and the width of each straight segment in the second straight section can be equal to each other, and the width of each straight segment in the third straight section and the width of each straight segment in the fourth straight section can be equal to each other. Alternatively, the width of each straight segment in the third or fourth straight section can be less than the width of each straight segment in the first or second straight section.

[0539] For example, the width of each straight portion in the first straight portion, the width of each straight portion in the second straight portion, the width of each curved portion in the first curved portion, and the width of each curved portion in the second curved portion can be A1 as described above, and the width of each straight portion in the third straight portion, the width of each straight portion in the fourth straight portion, the width of each curved portion in the third curved portion, and the width of each curved portion in the fourth curved portion can be A2 as described above. The descriptions of A1 and A2, as well as the description of the relationship between A1 and A2, can be applied equivalently.

[0540] The distances between the first straight sections, the distances between the first curved sections, the distances between the second straight sections, the distances between the second curved sections, the distances between the third straight sections, the distances between the third curved sections, the distances between the fourth straight sections, and the distances between the fourth curved sections can be as described in B1 above. The description in B1 can be applied.

[0541] The width A2 of the pattern of the fifth coil unit 230-3 of the OIS coil in the X-axis direction is configured to be smaller than the width A1 of the patterns of the third coil unit 230-1 and the fourth coil unit 230-2 of the OIS coil in the Y-axis direction. Therefore, this embodiment can reduce the difference between the electromagnetic force in the Y-axis direction and the electromagnetic force in the X-axis direction, thereby suppressing the dynamic tilt of the lens moving device caused by OIS operation.

[0542] The lens moving device 100 according to the above embodiments can be implemented as a camera module or an optical instrument, or can be used in camera modules or optical instruments in various fields.

[0543] For example, the lens moving device 100 according to the embodiment can be included in an optical instrument configured to use optical properties such as reflection, refraction, absorption, interference, and diffraction to form an image of an object in space to enhance the eye's visual power, record or reproduce an image formed by the lens, perform optical measurements, or transmit or propagate an image. For example, the optical instrument according to the embodiment may include a smartphone or portable terminal equipped with a camera.

[0544] Figure 19This is an exploded perspective view of the camera module 200 according to the embodiment.

[0545] Reference Figure 19 The camera module 200 may include a lens or lens barrel 400, a lens moving device 100, an adhesive member 612, a filter 610, a first retainer 600, a second retainer 800, an image sensor 810, a motion sensor 820, a controller 830, and a connector 840. Figure 19 The lens moving device 100 may be a lens moving device according to a previous embodiment.

[0546] The lens or lens barrel 400 can be installed in the winding frame 110 of the lens moving device 100.

[0547] The first retainer 600 may be arranged below the base 210 of the lens moving device 100. The filter 610 may be mounted to the first retainer 600, and the first retainer 600 may have a protrusion 500 on which the filter 610 sits.

[0548] The adhesive member 612 can connect or bond the base 210 of the lens moving device 100 to the first retainer 600. In addition to its adhesive function, the adhesive member 612 can also be used to prevent foreign objects from entering the lens moving device 100.

[0549] For example, the adhesive component 612 can be epoxy resin, thermosetting adhesive, or UV-curing adhesive.

[0550] Filter 610 can be used to prevent specific frequency band components of light passing through lens barrel 400 from incident on image sensor 810. Filter 610 can be an infrared cutoff filter; however, this disclosure is not limited thereto. In this case, filter 610 can be arranged parallel to the xy plane.

[0551] An opening can be formed in the region of the first retainer 600 where the filter 610 is mounted, through which light passing through the filter 610 is incident on the image sensor 810.

[0552] The second retainer 800 may be arranged below the first retainer 600, and the image sensor 810 may be mounted on the second retainer 600. The image sensor 810 is the area on which light passing through the filter 610 is incident to form an image included in the light.

[0553] The second holding member 800 may be provided with various circuits, components and controllers to convert the image formed on the image sensor 810 into an electrical signal and transmit the electrical signal to an external device.

[0554] The second retainer 800 can be implemented as a circuit board on which an image sensor can be mounted, on which a circuit pattern can be formed, and on which various components can be connected to each other.

[0555] The image sensor 810 can receive an image including light incident through the lens moving device 100, and can convert the received image into an electrical signal.

[0556] The filter 610 and the image sensor 810 can be arranged to be spaced apart from each other in a first direction opposite to each other.

[0557] The motion sensor 820 can be mounted on the second retainer 800 and can be connected to the controller 830 via a circuit pattern provided on the second retainer 800.

[0558] The motion sensor 820 outputs information about rotational angular velocity based on the motion of the camera module 200. The motion sensor 820 can be implemented as a two-axis or three-axis gyroscope sensor or an angular velocity sensor.

[0559] The controller 830 is mounted or disposed on the second retainer 800. The second retainer 800 may be connected to the lens moving device 100. For example, the second retainer 800 may be connected to the circuit board 190 of the lens moving device 100.

[0560] For example, a drive signal or power supply can be provided to the first coil 120 via the second holding member 800, and a drive signal or power supply can be provided to the second coil 230 via the second holding member 800.

[0561] For example, drive signals can be provided to the first position sensor 170 and the second position sensor 240 via the second retainer 800. The output signals of the first position sensor 170 and the second position sensor 240 can be sent to the second retainer 800. The output signals of the first position sensor 170 and the second position sensor 240 can be received by the controller 830.

[0562] Connector 840 can be connected to second retainer 800 and can have a port for connection to external devices.

[0563] Figure 20 This is a perspective view of a camera module 1000 according to another embodiment.

[0564] Reference Figure 20The camera module 1000 can be a dual-camera module, which includes a first camera module 100-1 with a first lens moving device and a second camera module 100-2 with a second lens moving device.

[0565] Each of the first camera module 100-1 and the second camera module 100-2 may be an autofocus (AF) camera module or an optical image stabilization (OIS) camera module.

[0566] An AF camera module is a camera module that can only perform autofocus, while an OIS camera module is a camera module that can perform both autofocus and optical image stabilization (OIS).

[0567] For example, the first lens moving device can be Figure 1 The embodiment 100 shown. The second lens moving device can be Figure 1 The embodiment 100 shown is a lens moving device for AF or a lens moving device for OIS.

[0568] The camera module 1000 may further include a circuit board 1100 on which a first camera module 100-1 and a second camera module 100-2 are mounted. Figure 20 In this embodiment, the first camera module 100-1 and the second camera module 100-2 are arranged side-by-side on a single circuit board 1100. However, this disclosure is not limited thereto. In another embodiment, the circuit board 1100 may include a first circuit board and a second circuit board that are separate from each other, the first camera module 100-1 may be arranged on the first circuit board, and the second camera module 100-2 may be arranged on the second circuit board.

[0569] The first camera module 100-1 can be arranged on the circuit board 1100 such that the dummy component 135 of the first lens moving device 100 of the first camera module 100-1 is positioned adjacent to the second camera module 100-2. This reduces magnetic field interference between the first magnet 130-1 to the third magnet 130-3 of the first camera module 100-1 and the magnets included in the second lens moving device of the second camera module 100-2. Therefore, the reliability of AF driving and / or OIS driving of each of the first camera module 100-1 and the second camera module 100-2 can be ensured.

[0570] Figure 21a Is Figure 20 A schematic diagram of embodiment 1000-1 of the camera module shown is provided. Figure 21bThe first lens moving device 100a and the second lens moving device 100b in Figure 21A are... Figure 3 A cross-sectional view along the AB direction.

[0571] Reference Figure 21a and Figure 21b The camera module 1000-1 may include a first camera module 100-1 having a first lens moving device 100a and a second camera module 100-2 having a second lens moving device 100b.

[0572] For example, each of the first camera module 100-1 and the second camera module 100-2 can be Figure 19 The camera module 200 shown is shown.

[0573] The first lens moving device 100a can be Figure 2 The embodiment 100 shown may also be configured such that the balancing magnet 185 is drawn from... Figure 2 The implementation shown is omitted.

[0574] The second lens moving device 100b can be Figure 2 The illustrated embodiment 100 is configured such that the balancing magnet 185 is drawn from... Figure 2 The embodiments shown omit certain devices. However, this disclosure is not limited thereto. For example, the second lens moving device 100b may be arranged adjacent to the first lens moving device 100a, and the second winding frame on which the lens is arranged may be moved along the optical axis or in a direction perpendicular to the optical axis.

[0575] Each of the first lens moving device 100 and the second lens moving device 100b may include: a housing 140 or 140A, the housing 140 or 140A including a first side portion and a second side portion opposite to each other, and a third side portion and a fourth side portion opposite to each other; a winding frame 110 or 110A disposed in the housing 140 or 140A; a first magnet 130-1 or 130-1A disposed at the first side portion of the housing 140 or 140A; and a second magnet 130-2 or 130-2A disposed at the second side portion of the housing 140 or 140A; A third magnet 130-3 or 130-3A is disposed on the third side portion of the housing 140 or 140A; a dummy member 135 or 135A is arranged on the fourth side portion of the housing 140 or 140A; and a first coil 120 includes a first coil unit 120-1 and a second coil unit 120-2, the first coil unit 120-1 being arranged at the winding frame 110 or 110A opposite to the first magnet 130-1 or 130-1A, and the second coil unit 120-2 being arranged at the winding frame 110 or 110A opposite to the second magnet 130-2 or 130-2A. The fourth side portion of the housing 140 of the first lens moving device 100a may be arranged adjacent to the fourth side portion or the third side portion of the housing 140A of the second lens moving device 100b. Furthermore, when viewed from above, the dummy component 135 of the first lens moving device 100a can be arranged between the third magnet 130-3 of the first lens moving device 100a and the dummy component 135A of the second lens moving device 100b.

[0576] For example, the first lens moving device 100a may include a "first lens moving unit," which includes a first winding frame 110, a first coil 120, a first magnet 130-1, a second magnet 130-2, a third magnet 130-3, a first dummy member 135, a first housing 140, an upper elastic member 150, a lower elastic member 160, a second coil 230, and a base 210.

[0592] For example, the fourth magnet 130-1A can be arranged between the second winding frame 110A (e.g., the first side of the second winding frame 110A) and the second housing 140A. For example, the fourth magnet 130-1A can be arranged at the second housing 140A to correspond to the first side of the second winding frame 110A.

[0593] The fifth magnet 130-2A can be arranged on the second side of the second winding frame 110A opposite to the first side of the second winding frame 110A, and the fifth magnet 130-2A can be arranged to be spaced apart from or adjacent to the second side of the second winding frame 110A.

[0594] For example, the fifth magnet 130-2A can be arranged between the second winding frame 110A (e.g., the second side of the second winding frame 110A) and the second housing 140A. For example, the fifth magnet 130-2A can be arranged at the second housing 140A to correspond to the second side of the second winding frame 110A.

[0595] The sixth magnet 130-3A can be arranged at the third side of the second winding frame 110A adjacent to the first side of the second winding frame 110A, and the sixth magnet 130-3A can be arranged to be spaced apart from or adjacent to the third side of the second winding frame 110A.

[0596] For example, the sixth magnet 130-3A can be arranged between the second winding frame 110A (e.g., the third side of the second winding frame 110A) and the second housing 140A. For example, the sixth magnet 130-3A can be arranged at the second housing 140A to correspond to the third side of the second winding frame 110A.

[0597] The first dummy component 135 may be arranged at the fourth side of the first winding frame 110 opposite to the third side of the first winding frame 110, and the first dummy component 135 may be arranged to be spaced apart from or adjacent to the fourth side of the first winding frame 110.

[0599] The first coil 120 of the first lens moving device 100a may include a first coil unit 120-1 arranged between the first winding frame 110 and the first magnet 130-1 and a second coil unit 120-2 arranged between the first winding frame 110 and the second magnet 130-2.

[0600] The first coil 120 of the second lens moving device 100b may include a third coil unit 120-1 arranged between the second winding frame 110A and the fourth magnet 130-1A and a fourth coil unit 120-2 arranged between the second winding frame 110A and the fifth magnet 130-2A.

[0601] The description of the first magnet 130-1 can be applied to the fourth magnet 130-1A, the description of the second magnet 130-2 can be applied to the fifth magnet 130-2A, and the description of the third magnet 130-3 can be applied to the sixth magnet 130-3A. Additionally, the description of the first dummy member 135 can be applied to the second dummy member 135A.

[0602] The first dummy member 135 and the second dummy member 135A can be arranged to overlap each other in the direction from the third magnet 130-3 to the sixth magnet 130-3A.

[0603] Alternatively, when viewed from above, the first dummy member 135 and the second dummy member 135A may be arranged to overlap each other in the direction from the first winding frame 110 (e.g., the fourth side) to the second winding frame 110A (e.g., the fourth side).

[0604] For example, the distance D11 between the first dummy component 135 and the second dummy component 135A can be less than the distance D12 (D11) between the magnet 130-2 (or magnet 130-1) of the first lens moving device 100a and the magnet 130-1A (or magnet 130-2A) of the second lens moving device 100b. <D12)。

[0605] Each of D11 and D12 can be a distance in a first horizontal direction. Here, the first horizontal direction can be the direction from the first winding frame 110 (e.g., the fourth side of the first winding frame 110) to the second winding frame 110A (e.g., the fourth side of the second winding frame 110A). Alternatively, the first horizontal direction can be the direction from the fourth side portion of the first housing 140 to the fourth side portion of the second housing 140A. The first horizontal direction can also be the direction from the third magnet 130-3 to the sixth magnet 130-3A.

[0606] Additionally, for example, the distance D11 can be less than the distance D13 (D11) between the magnet 130-3 of the first lens moving device 100a and the second dummy member 135A of the second lens moving device 100b. <D13)。

[0607] Additionally, for example, the distance D11 can be less than the distance D14 (D11) between the magnet 130-1 (or magnet 130-2) of the first lens moving device 100a and the second dummy member 135A of the second lens moving device 100b. <D14)。

[0608] Since D11 is smaller than D12, D13 and D14, the influence of magnetic field interference between the magnets 130-1 and 130-2 of the first lens moving device 100a and the second magnets 130-1A and 130-2A of the second lens moving device 100b on the AF driving force and OIS driving force can be reduced.

[0609] Additionally, the first position sensor 170 of the first lens moving device 100a and the first position sensor 170A of the first lens moving device 100b can be arranged at one of the corresponding locations in the fourth side portion of the first housing 140 and the fourth side portion of the second housing 140A, which are adjacent to each other.

[0610] The sensing magnet 180 (hereinafter referred to as "first sensing magnet") of the first lens moving device 100a may be arranged at a side portion (or a side surface) of the first winding frame 110 that corresponds to or is opposite to the fourth side portion of the first housing 140, for example, at the fourth side of the first winding frame 110.

[0611] The sensing magnet 180A (hereinafter referred to as the "second sensing magnet") of the second lens moving device 100b can be arranged at a side portion (or a side surface) of the second winding frame 110A that corresponds to or is opposite to the fourth side portion of the second housing 140A, for example, at the fourth side portion of the second winding frame 110A.

[0612] For example, the magnets 130-1 and 130-2 of the first lens moving device 100a and the magnets 130-1 and 130-2 of the second lens moving device 100b may overlap each other in the direction from the fourth side portion 141-4 of the first housing 140 (or the fourth side portion of the first winding frame 110) to the fourth side portion 141-4 of the second housing 140A (or the fourth side portion of the second winding frame 110A). However, this disclosure is not limited thereto.

[0613] For example, the coil units 120-1 and 120-2 of the first lens moving device 100a may overlap with the coil units 120-1 and 120-2 of the second lens moving device 100b in the direction from the fourth side portion 141-4 of the first housing 140 (or the fourth side portion of the first winding frame 110) to the fourth side portion 141-4 of the second housing 140A (or the fourth side portion of the second winding frame 110A). However, this disclosure is not limited thereto.

[0614] For example, the first sensing magnet 180 of the first lens moving device 100a may overlap with the second sensing magnet 180 of the second lens moving device 100b in the direction from the fourth side portion 141-4 of the first housing 140 (or the fourth side of the first winding frame 110) to the fourth side portion 141-4 of the second housing 140A (or the fourth side of the second winding frame 110A). However, this disclosure is not limited thereto. In another embodiment, the two may not overlap each other.

[0615] Additionally, for example, the magnet 130-3 of the first lens moving device 100a and the magnet 130-3A of the second lens moving device 100b may overlap each other in the direction from the fourth side portion 141-4 of the first housing 140 (or the fourth side of the first winding frame 110) to the fourth side portion 141-4 of the second housing 140A (or the fourth side of the second winding frame 110A).

[0616] Additionally, for example, the first dummy member 135 of the first lens moving device 100a and the second dummy member 135A of the second lens moving device 100b may overlap each other in the direction from the fourth side portion 141-4 of the first housing 140 (or the fourth side portion of the first winding frame 110) to the fourth side portion 141-4 of the second housing 140A (or the fourth side portion of the second winding frame 110A).

[0617] For example, the first dummy component 135 can be arranged between the magnet 130-3 of the first lens moving device 100a and the magnet 130-3A of the second lens moving device 100b.

[0618] For example, the first dummy component 135 may be arranged between the first winding frame 110 and the second winding frame 110A. Alternatively, for example, the second dummy component 135A may be arranged between the first winding frame 110 and the second winding frame 110A.

[0619] The second coil 230 of the first lens moving device 100a may include a coil unit 230-1 arranged below the magnet 130-1, a coil unit 230-2 arranged below the second magnet 130-2, and a coil unit 230-3 arranged below the third magnet 130-3.

[0620] Additionally, the second coil 230 of the second lens moving device 100b may include a coil unit 230-1 disposed below the magnet 130-1A, a coil unit 230-2 disposed below the second magnet 130-2A, and a coil unit 230-3 disposed below the third magnet 130-3A.

[0621] In another embodiment, the second lens moving device 100b may have the same... Figure 18a Different magnet arrangements. For example, a second lens moving device according to another embodiment may include magnets arranged at at least one of the four side portions 141-1 to 141-4 of the second housing 140A. For example, the second lens moving device may include four magnets arranged at the four side portions 141-1 to 141-4 of the second housing 140A. However, this disclosure is not limited thereto.

[0622] According to another embodiment, the second lens moving device may include magnets arranged at at least one of the four corners 142-1 to 142-4 of the second housing 140A. For example, the second lens moving device may include four magnets arranged at the four corners 142-1 to 142-4 of the second housing 140A. However, this disclosure is not limited thereto.

[0623] According to another embodiment, the camera module may include a first housing 140, a first winding frame 110 disposed in the first housing 140, magnets 130-1 to 130-3 disposed between the first housing 140 and the first winding frame 110, a coil 120 disposed between the magnets 130-1 to 130-3 and the first winding frame 110, and a dummy member 135 disposed between the first housing 140 and the first winding frame 110.

[0624] Additionally, the second lens moving unit may include a second housing 140A, a second winding frame 110a disposed in the second housing 140A, magnets 130-1A to 130-3A disposed between the second housing 140A and the second winding frame 110a, and a coil 120 disposed between the magnets 130-1A to 130-3A and the second winding frame 110a.

[0625] The magnets 130-1 to 130-3 of the first lens moving unit may include a first magnet 130-1 arranged at a first side of the first housing 140, a second magnet 130-2 arranged at a second side of the first housing 140 opposite to the first side of the first housing 140, and a third magnet 130-3 arranged at a third side of the first housing 140 adjacent to the first side of the first housing 140.

[0626] The dummy component 135 of the first lens moving unit can be arranged between the first winding frame 110 and the second winding frame.

[0627] Figure 22 This is a schematic diagram of a camera module 1000-2 according to another embodiment.

[0628] Figure 22The camera module 1000-2 includes: a first camera module 100-1 containing a first lens moving device 100a, a second camera module 100-2 containing a second lens moving device 100b, and a third camera module 100-3 containing a third lens moving device 100c. The first camera module 100-1, the second camera module 100-2, and the third camera module 100-3 can be arranged side by side.

[0629] exist Figure 22 The present invention describes an embodiment having a triple structure including three camera modules. However, this disclosure is not limited thereto. In another embodiment, two camera modules may be included ( Figure 19 (100-1 and 100-2). In yet another embodiment, four or more camera modules may be included, as shown in Figure 22.

[0630] For example, each of the first camera module 100-1, the second camera module 100-2, and the third camera module 100-3 can be Figure 19 The camera module 200 shown, and each of the first lens moving device 100a, the second lens moving device 100b, and the third lens moving device 100c can be Figure 2 The embodiment 100 shown may be configured such that from Figure 2 The embodiment shown omits the balancing magnet 185.

[0631] Since the first lens moving device 100a, the second lens moving device 100b, and the third lens moving device 100c can be arranged side by side adjacent to each other, and Figure 18b The description of d1 can be applied to the distance between these lens moving devices. The fourth side portion of one housing and the third side portion of the other housing of two adjacent lens moving devices can be arranged adjacent to each other.

[0632] For example, the fourth side portion 141-4 of the housing of the first lens moving device 100a and the third side portion 141-3 of the housing of the second lens moving device 100b can be arranged adjacent to each other.

[0633] Furthermore, the fourth side portion 141-4 of the housing of the second lens moving device 100b and the third side portion 141-3 of the housing of the third lens moving device 100c can be arranged adjacent to each other.

[0634] For example, the fourth side portion of the housing of the first lens moving device 100a and the third side portion of the housing of the second lens moving device 100b can be arranged adjacent to each other and parallel to each other, and the fourth side portion of the housing of the second lens moving device 100b and the third side portion of the housing of the third lens moving device 100c can be arranged adjacent to each other and parallel to each other.

[0635] The dummy component of one of two adjacent lens moving devices and the third magnet 135 of the other lens moving device can be arranged adjacent to each other.

[0636] For example, the distance D1 between the dummy component of one of two adjacent lens moving devices and the third magnet 135 of the other lens moving device can be smaller than the distance D2 (D1) between the first magnet 130-1 (or second magnet 130-2) of one of the two adjacent lens moving devices and the first magnet 130-1 (or second magnet 130-2) of the other lens moving device. <D2)。

[0637] Additionally, for example, the distance D1 can be less than the distance D3 (D1) between the third magnet 130-3 of one of two adjacent lens moving devices and the third magnet 130-3 of the other lens moving device. <D3)。

[0638] Additionally, for example, the distance D1 can be less than the distance D4 (D1) between the first magnet 130-1 (or the second magnet 130-2) of one of two adjacent lens moving devices and the third magnet 130-3 of the other lens moving device. <D4)。

[0639] Since D1 is smaller than D2 to D4, the influence of magnetic field interference between magnets included in two adjacent lens moving devices on the AF driving force and OIS driving force can be reduced, thus ensuring the reliability of AF operation and OIS operation.

[0640] Additionally, the position sensor of one of two adjacent lens moving devices (e.g., 100-1 and 100-2 or 100-2 and 100-3) and the third magnet 130-3 of the other lens moving device can be arranged at corresponding positions in one of the adjacent third side portions and fourth side portions of the two adjacent housings.

[0641] Additionally, the sensing magnet of one of the two adjacent lens moving devices can be arranged on the side portion (or side surface) of the winding frame corresponding to or opposite the fourth side portion, which is one of the third and fourth side portions of two adjacent housings.

[0642] The sensing magnet of the other lens moving device in two adjacent lens moving devices can be arranged on a side portion (or side surface) of the winding frame that corresponds to or is opposite to a fourth side portion positioned opposite to the third side portion, the fourth side portion being one of the adjacent third side portion and the fourth side portion.

[0643] For example, in the direction from the fourth side portion of one of the two adjacent housings to the third side portion of the other housing, the first magnet 130-1 and the second magnet 130-2 are arranged in one housing, and the first magnet 130-1 and the second magnet 130-2 arranged in the other housing may not overlap each other.

[0644] For example, in the direction from the fourth side portion of one of the two adjacent housings to the third side portion of the other housing, the first coil unit 120-1 and the second coil unit 120-2 of one of the two adjacent lens moving devices may not overlap with the first coil unit 120-1 and the second coil unit 120-2 of the other of the two adjacent lens moving devices.

[0645] For example, in the direction from the fourth side portion of one of the two adjacent housings to the third side portion of the other housing, the sensing magnet 180 of one of the two adjacent lens moving devices may overlap with the sensing magnet 180 of the other of the two adjacent lens moving devices. However, this disclosure is not limited thereto. In another embodiment, they may not overlap each other.

[0646] Additionally, for example, in the direction from the fourth side portion of one of the two adjacent housings to the third side portion of the other housing, the two third magnets 130-3 of the two adjacent lens moving devices can overlap each other.

[0647] For example, in the direction from the fourth side portion of one of the two adjacent housings to the third side portion of the other housing, the two dummy members 135 of the two adjacent lens moving devices can overlap each other.

[0648] exist Figure 22 In this embodiment, the dummy component and the third magnet are arranged on the side portions of two adjacent housings. Therefore, embodiment 1000-2 can reduce the impact of magnetic field interference between the first magnet 130-1 and the second magnet 130-3 included in adjacent lens moving devices on the AF driving force and OIS driving force, thereby ensuring the reliability of AF operation and OIS operation.

[0649] When comparing Figure 21a Implementation methods and Figure 22 When implementing the method, Figure 21aThe distance between the two third magnets 130-3 and 130-3A of the two camera modules (e.g., 100-1 and 100-2) is greater than Figure 22 The distance between the two third magnets 130-3 of two adjacent camera modules (e.g., 100-1 and 100-2). Thus, in Figure 21a The reduction effect of magnetic field interference in the proposed implementation method can be even better.

[0650] Figure 23a Showing the direction Figure 22 The simulation results of the force applied by the third magnet 130-3 and the sensing magnet 180 of the camera module 1000-2, and Figure 23b It shows Figure 22 Simulation results of the stroke change (displacement) of the third magnet 130-3 and sensing magnet 180 of the camera module. Figure 23a and Figure 23b In the text, OIS represents magnets 130-1 and 130-2, and Smagnet represents sensing magnet.

[0651] Figure 23a and Figure 23b Simulation results of force and stroke variations at the initial position of the lens moving device in each camera module are shown. Here, the initial position of the lens moving device can be the original position of the OIS moving unit when no drive signal is provided to the first coil 120 and the second coil 230, or the position of the OIS moving unit where the upper elastic member 150, lower elastic member 160, and support member 220 elastically deform only due to the weight of the OIS moving unit. Alternatively, the initial position can be the position of the OIS moving unit when gravity acts in the direction from the winding frame 110 to the base 210, or when gravity acts in the direction from the base 210 to the winding frame 110.

[0652] Assume the spring constant of the OIS is 60 mN / mm in the X and Y axes, and 500 mN / mm in the Z axis. Assume the distance between two adjacent camera modules is 0.75 mm, the length of each camera module in the horizontal and vertical directions is 12 mm, and the thickness of each camera module is 3.3 mm.

[0653] Reference Figure 23aAs can be seen, the force applied to the third magnet 130-3 of each of the camera modules 100-1 to 100-3 due to magnetic field interference is less than 0.5 mN in both the positive (+) and negative (-) directions. Additionally, it can be seen that the force applied to the sensing magnet 180 of each of the camera modules 100-1 to 100-3 due to magnetic field interference is less than 0.5 mN in both the positive (+) and negative (-) directions.

[0654] Here, "less than 0.5mN" is merely an analysis error based on simulation. Therefore, it can be estimated that the force exerted on the third magnet 130-3 and sensing magnet 180 of each of the camera modules 100-1 to 100-3 due to magnetic field interference is essentially negligible.

[0655] For example, the force applied to the third magnet 130-3 of a camera module may include the force applied to magnets 130-1, 130-2 and 130-3 and the sensing magnet 180 included in each of the first camera modules 100-1 to the third camera modules 100-3, excluding the force applied to the third magnet 130-3 of the camera module.

[0656] Additionally, the force applied to the sensing magnet 180 of a camera module may include the force applied to the sensing magnet 180 included in magnets 130-1, 130-2, and 130-3, as well as in each of the first camera modules 100-1 to the third camera modules 100-3, excluding the force applied to the sensing magnet 180 of the camera module.

[0657] Reference Figure 23b As can be seen, the travel variation of the third magnet 130-3 in each of the camera modules 100-1 to 100-3 caused by magnetic field interference is less than 5 μm from the initial position in the positive (+) direction and the negative (-) direction.

[0658] Additionally, it can be observed that the travel variation of the sensing magnet 180 in each of the camera modules 100-1 to 100-3 due to magnetic field interference is less than 2 μm from the initial position in the positive (+) and negative (-) directions.

[0659] The travel variation of less than 5 μm for the third magnet 130-3 and less than 2 μm for the sensing magnet 180 are merely analytical errors based on simulation. Therefore, it can be estimated that the travel variation of the third magnet 130-3 and the sensing magnet 180 in each of the camera modules 100-1 to 100-3 due to magnetic field interference is essentially negligible.

[0660] based on Figure 23a and Figure 23b The simulation results can ensure the reliability of the camera module's AF and OIS operations according to the implementation method.

[0661] Furthermore, since the first lens moving device 100a, the second lens moving device 100b, and the third lens moving device 100c are arranged in the same direction, they can use the same coordinate axis, and therefore, since different coordinate axes are used, it is not necessary to correct the position information of the gyroscope sensor. Figure 21a and Figure 21b In this process, the first lens moving device 100a and the second lens moving device 100b use different coordinate axes. Since they are arranged in a left-right symmetrical manner, and therefore, due to the use of different coordinate axes, it is necessary to correct the position information of the gyroscope sensor.

[0662] Figure 24 This is a schematic diagram of a camera module 1000-3 according to yet another embodiment.

[0663] Reference Figure 24 The camera module 1000-3 may include a first camera module 100-1 containing a first lens moving device 100a and a second camera module 100-4 containing a second lens moving device 100d.

[0665] The second lens moving device 100d can be a closed-loop autofocus (CLAF) lens moving device, and the second camera module 100-4 can include a CLAF lens moving device instead. Figure 19 The lens moving device 100 of the camera module 200 shown.

[0666] Figure 25 It shows Figure 24 An embodiment of the second lens moving device 100d.

[0667] Reference Figure 25 The second lens moving device 100d may include a winding frame 1110, a coil 1120, a first magnet 1130-1, a second magnet 1130-2, a housing 1140, an upper elastic member 1150, a lower elastic member 1160, a circuit board 1190, a position sensor 1170, and a sensing magnet 1180.

[0668] Additionally, the second lens moving device 100d may include a balancing magnet 1185, a cover member 1300, and a base 1210.

[0669] The winding frame 1110 may have an opening in which a lens or lens barrel is mounted.

[0670] Coil 1120 may be arranged on the outer surface of winding frame 1110. For example, coil 1120 may have a closed, curved shape, such as a loop, wherein the coil is wound around the outer peripheral surface of winding frame 1100 in the direction of rotation about the optical axis. However, this disclosure is not limited thereto. In another embodiment, coil 1120 may include a first coil unit opposite to first magnet 1130-1 and a second coil unit opposite to second magnet 1130-2. Each of the first and second coil units may be a coil loop or a loop-shaped coil block and may be fixed to the outer surface of winding frame 1110. The first and second coil units may be connected to each other.

[0671] The sensing magnet 1180 can be disposed on one side portion (or one side surface) of the winding frame 1110, and the balancing magnet 1185 can be disposed on another side portion (or another side surface) of the winding frame 1110 opposite to the aforementioned one side portion. The balancing magnet 1185 can counteract or reduce the influence of electromagnetic forces formed by magnetic field interference between the sensing magnet 1180 and the first magnet 130-1 and the second magnet 130-2.

[0672] The winding frame 1110 may have a first seating recess in one side portion, in which the sensing magnet 1180 is seated, and the winding frame 1110 may have a second seating recess in the other side portion, in which the balancing magnet 1185 is seated.

[0673] The sensing magnet 1180 can be arranged inside the coil 1120 in a state where it is arranged in the first seating recess, and the balancing magnet 1185 can be arranged inside the coil 1120 in a state where it is arranged in the second seating recess. Here, the interior of the coil 1120 can be the side of the coil 1120 facing the center of the winding frame 1110.

[0674] The housing 1140 may include an opening configured to receive a winding frame 1110, at which a coil 1120 is disposed, wherein the winding frame 1110 may be disposed inside the housing 1140.

[0675] For example, housing 1140 may include first side portions 1141-1 to fourth side portions 1141-4 spaced apart from each other, and first corner portions to fourth corner portions spaced apart from each other. The first side portions 1141-1 and second side portions 1141-2 of housing 1140 may be opposite to each other. The third side portions 1141-3 and fourth side portions 1141-4 of housing 1140 may be located between the first side portions 1141-1 and the second side portions 1141-2 of housing 1140, and may be opposite to each other.

[0676] The first magnet 1130-1 can be arranged at the first side portion 1141-1 of the housing 1140, and the second magnet 1130-2 can be arranged at the second side portion 1141-2 of the housing 1140.

[0679] For example, circuit board 1190 may be arranged on the outer surface of the fourth side portion 1141-4 of housing 1140, and position sensor 1170 may be arranged or mounted on circuit board 1190.

[0680] The sensing magnet 1180 can be arranged on the side portion 1110-4 (or side surface) of the winding frame 1110, which corresponds to or is opposite to the fourth side portion 1141-4 of the housing 1140.

[0681] The balancing magnet 1185 can be arranged on the side portion 1110-3 (or side surface) of the winding frame 1110, which corresponds to or is opposite to the third side portion 1141-3 of the housing 1140.

[0682] In another embodiment, the circuit board 1190 and the position sensor 1170 may be arranged on the third side portion 1141-3 of the housing 1140, the sensing magnet 1180 may be arranged on the side portion (or side surface) of the winding frame 1110 corresponding to the third side portion 1141-3 of the housing 1140, and the balancing magnet 1185 may be arranged on the side portion 1110-4 of the winding frame 1110 corresponding to the fourth side portion 1141-4 of the housing 1140.

[0683] The winding frame 1110 can be moved along the optical axis by the electromagnetic force generated by the electromagnetic interaction between the coil 1120 and the first magnet 1130-1 and the second magnet 1130-2. The position sensor 1170 can sense the change in the magnetic field strength of the sensing magnet 1180 mounted to the winding frame 1110 due to the movement of the winding frame 1110, and can output an output signal (e.g., an output voltage) based on the sensing result. The position sensor 1170 can be a Hall sensor or a driver IC including a Hall sensor and a driver.

[0684] The upper elastic member 1150 may be connected to the upper portion, upper surface, or upper end of the winding frame 1110, and to the upper portion, upper surface, or upper end of the housing 1140. For example, the upper elastic member 1150 may include at least one upper spring.

[0685] The lower elastic member 1160 may be connected to the lower portion, lower surface, or lower end of the winding frame 1110, and also to the lower portion, lower surface, or lower end of the housing 1140. For example, the lower elastic member 1160 may include at least one lower spring.

[0686] For example, at least one of the upper elastic member 1150 and the lower elastic member 1160 may include two or more springs that are separate from each other.

[0687] The coil 1120 can be connected to at least one of the upper elastic member 1150 and the lower elastic member 1160. In addition, at least one of the upper elastic member 1150 and the lower elastic member 1160 can be connected to the circuit board 1190.

[0688] The circuit board 1190 may include multiple terminals for external connection. The position sensor 1170 may be connected to a corresponding terminal of the multiple terminals of the circuit board 1190.

[0689] The coil 1120 can be connected to a corresponding terminal of a plurality of terminals of the circuit board 1190 via the upper elastic member 1150 or the lower elastic member 1160.

[0690] The base 1210 may be arranged below the housing 1140. For example, the base 1210 may be arranged below the lower elastic member 1160.

[0691] The cover member 1300 can be formed in the shape of a box. The lower portion of the cover member 1300 is open, and the cover member 1300 includes a top plate and side plates. The cover member 1300 can cover the housing 1140 and the winding rack 1110. The lower portion of the cover member 1300 can be connected to the lower portion of the base 1210. The base 1210 and the cover member 1300 can form a receiving space for the winding rack 1110 and the housing 1140.

[0692] The base 1210 may have an opening corresponding to the opening of the winding frame 1110 and / or the opening of the housing 1140.

[0693] The housing 1140 may have guide recesses 1148 in its first to fourth corner portions, the guide portion 1216 of the base 1210 is inserted into the guide recesses 1148, and the guide portion 1216 of the base 1210 may be fastened or connected to the guide recesses 1148 using adhesive members such as epoxy resin or silicone resin (not shown).

[0694] Reference Figure 24 and Figure 25 The first lens moving device 100a and the second lens moving device 100b can be arranged adjacent to each other, and Figure 21a and Figure 21b The description of d1 can be applied to the distance between the first lens moving device 100a and the second lens moving device 100b.

[0695] The first lens moving device 100a may include: a first housing 140, the first housing 140 including a first side portion and a second side portion opposite to each other, and a third side portion and a fourth side portion opposite to each other; a first winding frame 110 disposed in the first housing 140; a first magnet 130-1 disposed at the first side portion of the first housing 140; a second magnet 130-3 disposed at the second side portion of the first housing 140; a third magnet 130-3 disposed at the third side portion of the first housing 140; a dummy member 135 and a first coil sensor 170 disposed at the fourth side portion of the first housing 140; a first coil 120, the first coil 120 including a first coil unit 120-1 disposed at the first winding frame 110 opposite to the first magnet 130-1, and a first winding frame 110 The second coil unit 120-2 is arranged opposite to the second magnet 130-2; and the sensing magnet 180 (or the fourth magnet) is arranged opposite to the first position sensor 170 at the first winding frame.

[0696] The second lens moving device 100d may include: a second winding frame 1110; a coil 1120 disposed on the second winding frame 1110; a first magnet 1130-1 and a second magnet 1130-2 opposite to the coil 1120; a position sensor 1170; and a sensing magnet 1180 (or a third magnet) disposed on the second winding frame 1110 opposite to the position sensor 1170. Additionally, when viewed from above, a first dummy member 135 of the first lens moving device 100a may be disposed between the third magnet 130-3 of the first lens moving device 100a and the sensing magnet 1180 of the second lens moving device 100d.

[0697] The fourth side portion 141-4 of the first housing 140 of the first lens moving device 100a and the third side portion 1141-3 of the second housing 1140 of the second lens moving device 100d can be arranged adjacent to each other.

[0698] For example, the fourth side portion 141-4 of the first housing 140 and the third side portion 1141-3 of the second housing 1140 may be arranged parallel to each other. However, this disclosure is not limited thereto.

[0699] The dummy component 135 of the first lens moving device 100a and the balancing magnet 1185 of the second lens moving device 100d can be arranged at a corresponding location in the fourth side portion 141-4 of the first housing 140 and the third side portion 1141-3 of the second housing 1140, wherein the fourth side portion 141-4 and the third side portion 1141-3 are positioned adjacent to each other.

[0700] For example, the distance D21 between the dummy component 135 and the balancing magnet 1185 can be smaller than the distance D22 between the first magnet 130-1 (or the second magnet 130-2) of the first lens moving device 100a and the first magnet 1130-1 (or the second magnet 1130-2) of the second lens moving device 100d. <D22)。

[0701] Additionally, for example, the distance D21 can be less than the distance D23 (D21) between the third magnet 130-3 of the first lens moving device 100a and the balancing magnet 1185 of the second lens moving device 100d. <D23)。

[0702] Additionally, for example, the distance D21 can be less than the distance D24 (D21) between the first magnet 130-1 (or the second magnet 130-2) of the first lens moving device 100a and the balancing magnet 1185 of the second lens moving device 100d. <D24)。

[0703] Since D21 is smaller than D22, D23 and D24, the influence of magnetic field interference between the first magnet 130-1 and the second magnet 130-2 of the first lens moving device 100a and the first magnet 1130-1 and the second magnet 1130-2 of the second lens moving device 100d on the AF driving force and OIS driving force can be reduced.

[0704] For example, the first magnet 130-1 and the second magnet 130-2 of the first lens moving device 100a and the first magnet 1130-1 and the second magnet 1130-2 of the second lens moving device 100d may not overlap with each other in the direction from the fourth side portion 141-4 of the first housing 140 to the third side portion 1141-3 of the second housing 1140.

[0705] For example, the sensing magnet 180 of the first lens moving device 100a may overlap with the balancing magnet 1185 of the second lens moving device 100d in the direction from the fourth side portion 141-4 of the first housing 140 to the third side portion 1141-3 of the second housing 1140. However, this disclosure is not limited thereto. In another embodiment, the two may not overlap each other.

[0706] According to another embodiment, the second lens moving device may have the same... Figure 24 and Figure 25 Different magnet arrangements. For example, as Figure 24 and Figure 25 A modification of the second lens moving device according to another embodiment may include a magnet arranged at at least one of the four side portions of the housing of the second lens moving device. For example, the second lens moving device according to another embodiment may include four magnets arranged at the four side portions of the housing. However, this disclosure is not limited thereto.

[0707] In addition, as Figure 24 and Figure 25 The modification can be achieved using the following steps. According to another embodiment, the second lens moving device may include magnets arranged at at least one of the four corners of the housing of the second lens moving device. For example, according to another embodiment, the second lens moving device may include four magnets arranged at the four corners of the housing. However, this disclosure is not limited thereto.

[0708] Figure 26a An example arrangement of the magnets, sensing magnets, and balancing magnets of the two adjacent lens moving devices of the dual cameras is shown.

[0709] Reference Figure 26aThe dual cameras may include a first camera module 10-1 and a second camera module 10-2. The first camera module 10-1 includes a first lens moving device 10a for OIS, and the second camera module 10-2 includes a second lens moving device 10b for CLAF.

[0710] The fourth side portion of the first housing (not shown) of the first lens moving device 10a for OIS and the fourth side portion of the second housing (not shown) of the second lens moving device 10b for CLAF can be arranged adjacent to each other.

[0711] The first lens moving device 10a for OIS may include four magnets DM1 to DM4, a first sensing magnet SM1, and a first balancing magnet BM1.

[0712] The four magnets DM1 to DM4 can be arranged on the first side portion to the fourth side portion of the first housing. The first sensing magnet SM1 can be arranged on a side portion (or a side surface) of the winding frame corresponding to the first corner of the first housing. The first corner of the first housing is adjacent to the fourth side portion of the first housing. The first balancing magnet BM1 can be arranged on a side portion of the winding frame opposite to the side portion where the first sensing magnet SM1 is arranged.

[0713] The second lens moving device 10b for CLAF may include two magnets DM11 and DM12 disposed at a first side portion and a second side portion of the second housing, a second balancing magnet BM2 disposed at a side portion of the winding frame opposite to a fourth side portion of the second housing, and a second sensing magnet SM2 disposed at another side portion of the winding frame corresponding to or opposite to a third side portion of the second housing, the third side portion of the second housing being opposite to the fourth side portion of the second housing. The positions of the second balancing magnet BM2 and the second sensing magnet SM2 may be interchanged (reversed).

[0714] exist Figure 26aIn this configuration, the OIS magnet is positioned at one of the fourth side portions of the first housing and the fourth side portion of the second housing. Consequently, the second balancing magnet (or second sensing magnet) of the second lens moving device 10b for the CLAF is subjected to significant magnetic field interference due to the magnet DM4 of the first lens moving device 10a for the OIS. Furthermore, due to the magnetic field interference between the magnet DM4 of the first lens moving device 10a for the OIS and the magnets DM11 and DM12 of the second lens moving device 10b for the CLAF, the reliability of the AF operation and OIS operation of the first lens moving device 10a for the OIS, and the AF operation of the second lens moving device 10b for the CLAF, may be degraded.

[0715] Figure 26b Another example of the arrangement of magnets, sensing magnets, and balancing magnets for the adjacent lens moving devices of the dual cameras is shown.

[0716] To reduce reference Figure 26a The described effects of magnetic field interference can be mitigated by arranging magnets DM21 to DM24, sensing magnet SM3, and balancing magnet BM3 in the first lens moving device 10c for OIS, as follows: Figure 26b As shown in the image.

[0717] The first lens moving device 10c may include a first housing, the first housing including a first corner and a second corner opposite to each other in the diagonal direction, and a third corner and a fourth corner opposite to each other in the diagonal direction, a first winding frame arranged in the first housing, a coil arranged at the first winding frame, first magnets DM21 to DM24 arranged at the first corner to the fourth corner of the first housing, a position sensor arranged between the first corner and the third corner of the first housing, and a sensing magnet SM3 (or a second magnet) arranged at the first winding frame opposite to the position sensor.

[0718] The second lens moving device 10b may include a second winding frame, a coil arranged on the second winding frame, a first magnet DM11 and a second magnet DM12 opposite to the coil, a position sensor 1170, and a sensing magnet SM2 (or a third magnet) arranged on the second winding frame opposite to the position sensor. The second lens moving device 10b may be arranged adjacent to the second corner and the third corner of the first housing of the first lens moving device 10c, and the directions in which the first magnet DM11 and the second magnet DM12 of the second lens moving device 10b are opposite to each other may correspond to the directions in which the third corner and the second corner of the first housing of the first lens moving device 10c are connected to each other.

[0719] The fourth side portion of the first housing of the first lens moving device 10c and the fourth side portion of the second housing of the second lens moving device 10b can be arranged adjacent to each other. The third side portion of the first housing can be opposite to the fourth side portion of the first housing, and the first side portion and the second side portion of the first housing can be arranged opposite each other between the third side portion and the fourth side portion of the first housing.

[0720] Magnets DM21 to DM24 can be arranged at the corner portions of the first housing of the first lens moving device 10c. Each corner portion of the first housing of the first lens moving device 10c can be arranged at two adjacent side portions among the first side portions to the fourth side portions of the first housing.

[0721] The sensing magnet SM3 can be arranged on the side surface of the winding frame opposite to the first side portion of the first housing, and the balancing magnet BM3 can be arranged on the side portion of the winding frame opposite to the second side portion of the first housing. Furthermore, the positions of the balancing magnet BM3 and the sensing magnet SM3 can be interchanged.

[0722] exist Figure 26b In this configuration, magnets DM21 to DM24 are arranged at the corner portion of the first housing. Consequently, the first and second lens moving devices have different coordinate axes for indicating the OIS driving direction, and therefore the position information values ​​of the gyroscope sensor need to be corrected. As a result, the driving speed of the camera module may be reduced.

[0723] In addition, Figure 26b In this process, a balancing magnet is necessary to counteract the magnetic field interference of the sensing magnet in the first lens moving device 10c.

[0724] In addition, Figure 26b In this design, the position sensor must be positioned on a first side portion of the first housing opposite the side portion of the winding frame where the sensing magnet SM3 is located. However, since the magnet is positioned at a corner adjacent to the first side portion of the first housing, the space available for mounting the position sensor is insufficient. In particular, the integrated AF driver IC, which includes the Hall sensor and the driver, may not be mounted in the first housing because of its large size.

[0725] According to an embodiment, on the other hand, in a camera module comprising two or more lens moving devices, a dummy member 135 is arranged at one of the two adjacent side portions of the two housings of two adjacent lens moving devices, but no magnet for AF or OIS is arranged there. Therefore, the impact on the AF driving force and OIS driving force due to magnetic field interference between magnets contained in two adjacent lens moving devices can be reduced, and thus the reliability of AF operation and OIS operation can be ensured.

[0726] Because this implementation includes three magnets, the cost of the magnets can be reduced.

[0727] Furthermore, since this embodiment includes three magnets, even if a balancing magnet is not arranged on the side portion of the winding frame opposite to the side portion of the winding frame where the sensing magnet is positioned, the third magnet 130-3 is also used as a balancing magnet, thereby achieving the effect of counteracting the magnetic field interference of the sensing magnet.

[0728] Furthermore, in the embodiment, since no magnet is arranged at the fourth side portion 141-4 of the housing, sufficient space can be ensured to install the position sensor in the housing.

[0729] Furthermore, in the embodiments, the magnet is such as Figure 22 With the arrangement shown, there is no need to convert the gyroscope values ​​of the gyroscope sensor, thereby increasing the driving speed of the camera module.

Figure 29 yes Figure 28 Exploded perspective view of the first AF moving part 5200a and the second AF moving part 5200b. Figure 30 This is an exploded perspective view of the OIS moving part 5300.

Figure 34 yes Figure 33 A magnified view of a portion of the image, and Figure 35 yes Figure 27A cross-sectional view when viewed along the XY direction.

[0731] Because two lens modules can be installed, therefore Figure 27 The lens moving device 3100 may be referred to, for example, as a "dual-lens moving device". Furthermore, in the following description, "coil" may refer to a coil unit, and "elastic member" may refer to an elastic unit or a spring.

[0732] Reference Figures 27 to 35 The lens moving device 3100 may include a cover member 3300, a first AF moving member 5200a, a second AF moving member 5200b, an OIS moving member 5300, a stator 5400, a first elastic member 5500a, a second elastic member 5500b, and a sensor 5800.

[0733] In addition, the lens moving device 3100 may also include a support member 3600 and a damper 5700.

[0734] However, in another embodiment, at least one of the cover member 3300, the first AF moving member 5200a, the second AF moving member 5200b, the OIS moving member 5300, the stator 5400, the first elastic member 5500a, the second elastic member 5500b, the support member 3600, the damper 5700, and the sensor 5800 can be omitted from the lens moving device 3100. In particular, the sensor 5800 configured to perform hand tremor compensation feedback control can be omitted.

[0735] In terms of AF driving, the lens moving device 3100 may include a first lens moving unit and a second lens moving unit. The first lens moving unit may, for example, include a first magnet unit, which includes a first AF moving member 5200a and first magnets 3130-1 to third magnets 3130-3.

[0736] In addition, the second lens moving unit may include, for example, a second magnet unit, which includes a second AF moving member 5200b and a fourth magnet 3130-4 to a sixth magnet 3130-6.

[0737] The cover member 3300 can define the appearance of the lens moving device 3100.

[0738] The cover member 3300 may have a hexahedral opening at its lower portion. However, this disclosure is not limited thereto. The cover member 3300 may be made of a non-magnetic material. In the case that the cover member 3300 is made of a non-magnetic material, the magnet 3130 may be affected by the magnetic force of the cover member 3300. The cover member 3300 may be made of a metallic material.

[0739] More specifically, a metal sheet can be used as the cover member 3300. In this case, the cover member 3300 can block electromagnetic interference (EMI). Due to this property of the cover member 3300, the cover member 3300 can be referred to as an "EMI shield".

[0740] The cover member 3300 can prevent electromagnetic waves generated outside the lens moving device from being introduced into the interior of the cover member 3300. In addition, the cover member 3300 can prevent electromagnetic waves generated inside the lens moving device from being released to the exterior of the cover member 3300.

[0741] The cover member 3300 may include an upper plate 3301 and a side plate 3302.

[0742] The cover member 3300 may include an upper plate 3301 and a side plate 3302 that bends and extends from the upper plate 3301. The cover member 3300 may include an upper plate 3301 and a side plate 3302 that extends downward from the outer periphery of the upper plate 3301.

[0743] The cover member 3300 may be connected to the base 3210. For example, a portion of the side plate 3302 of the cover member 3300 may be connected to the base 3210.

[0744] The lower end of the side plate 3302 of the cover member 3300 can be disposed at the stepped portion 3211 of the base 3210. The lower end of the side plate 3302 can be connected to the base 3210. The inner surface of the side plate 3302 of the cover member 3300 can directly contact the outer surface of the base 3210.

[0745] The inner surface of the side plate 3302 of the cover member 3300 can be attached to the base 3210 using an adhesive (not shown). In another example, the cover member 3300 can be directly attached to the upper surface of the circuit board 5010.

[0746] At least one of the first AF moving member 5200a, the second AF moving member 5200b, the OIS moving member 5300, the stator 5400, the first elastic member 5500a, the second elastic member 5500b, and the support member 3600 can be arranged in the internal space defined by the cover member 3300 and the base 3210. In this structure, the cover member 3300 can protect the internal components from external impacts and prevent the penetration of external contaminants. The cover member 3300 can be integrally formed.

[0747] The cover member 3300 may include a first opening 3302a and a second opening 3302b. Each of the first opening 3302a and the second opening 3302b may, for example, be a through hole formed through the upper plate 3301 of the cover member 3300.

[0748] The cover member 3300 may have a first opening 3302a and a second opening 3302b in the upper plate 3301 of the cover member 3300. The first opening 3302a is formed at a position corresponding to the first winding frame 3110a, and the second opening 3302b is formed at a position corresponding to the second winding frame 3110b.

[0749] The openings 3302a and 3302b of the cover member 3300 can be formed in the upper plate 3301 of the cover member 3300 to be spaced apart from each other. The first opening 3302a of the cover member 3300 can expose the first lens module mounted in the first winding frame 3110a, and the second opening 3302b of the cover member 3300 can expose the second lens module mounted in the second winding frame 3110b.

[0750] The first opening 3302a of the cover member 3300 can be formed in a shape corresponding to the shape of the first lens module, and the second opening 3302b of the cover member 3300 can be formed in a shape corresponding to the shape of the second lens module.

[0751] The size (e.g., diameter) of each of the first opening 3302a and the second opening 3302b of the cover member 3300 may be larger than the diameter of a corresponding lens module in the lens module, such that the lens module can be assembled through the openings 3302a and 3302b.

[0752] Light introduced through each of the first opening 3302a and the second opening 3302b of the cover member 3300 can pass through a corresponding lens module in the lens module. After passing through each lens module, the light can then be converted into an electrical signal by an image sensor to obtain an image.

[0753] The first AF moving part 5200a and the second AF moving part 5200b will be described.

[0754] The first AF moving member 5200a is connected to the first lens module, or the first AF moving member 5200a houses the first lens module. The second AF moving member 5200b is connected to the second lens module, or the second AF moving member 5200b houses the second lens module.

[0755] Each of the first AF moving member 5200a and the second AF moving member 5200b can move through interaction with the OIS moving member 5300 and / or the stator 5400. In this case, the first AF moving member 5200a can move integrally with or together with the first lens module to perform an autofocus function, and the second AF moving member 5200b can move integrally with or together with the second lens module. However, the second AF moving member 5200b can also move separately from the first AF moving member 5200a. The direction of movement of the second AF moving member 5200b and the direction of movement of the first AF moving member 5200a can be parallel to each other.

[0756] For example, the outer peripheral surface of the first lens module can be connected to the inner peripheral surface of the first AF moving member 5200a, and the outer peripheral surface of the second lens module can be connected to the inner peripheral surface of the second AF moving member 5200b.

[0757] The first AF moving member 5200a may include a first winding frame 3110a and a component configured to move together with the first winding frame 3110a, and the second AF moving member 5200b may include a second winding frame 3110b and a component configured to move together with the second winding frame 3110b.

[0763] Each of the first winding frame 3110a and the second winding frame 3110b can move relative to the housing 3140 in the direction of the optical axis.

[0764] The first winding frame 3110a can be arranged in the first receiving unit 3011a of the housing 3140 to move along the first optical axis, and the second winding frame 3110b can be arranged in the second receiving unit 3011b of the housing 3140 to move along the second optical axis.

[0765] The first winding frame 3110a may have a first opening 3111a for connection with the first lens module, and the first opening 3111a may be a through hole formed through the center of the first winding frame 3110a.

[0766] The second winding frame 3110b may have a second opening 3111b for connection with the second lens module, and the second opening 3111b may be a through hole formed through the center of the second winding frame 3110b.

[0767] For example, the outer peripheral surface of the first lens module can be connected to the inner peripheral surface of the first winding frame 3110a formed by the first opening 3111a, and the outer peripheral surface of the second lens module can be connected to the inner peripheral surface of the second winding frame 3110b formed by the second opening 3111b.

[0768] For example, the thread corresponding to the thread formed on the outer peripheral surface of the first lens module can be formed on the inner peripheral surface of the first opening 3111a, and the thread corresponding to the thread formed on the outer peripheral surface of the second lens module can be formed on the inner peripheral surface of the second opening 3111b.

[0769] For example, the first lens module can be threaded into the first opening 3111a of the first winding frame 3110a, and the second lens module can be threaded into the second opening 3111b of the second winding frame 3110b.

[0770] For example, an adhesive can be applied between the first lens module and the first winding frame 3110a, and between the second lens module and the second winding frame 3110b. In this case, the adhesive can be an epoxy resin that is cured by at least one of ultraviolet (UV) light, heat, and laser.

[0773] The first winding frame 3110a may have a first drive unit connection portion 3212a on its outer surface, and the first coil 3120a may be arranged at the first drive unit connection portion 3212a or connected to the first drive unit connection portion 3212a.

[0777] For example, the first drive unit connection portion 3212a may be continuously formed along the outer surface of the first winding frame 3110a, and the second drive unit connection portion 3212b may be continuously formed along the outer surface of the second winding frame 3110b.

[0778] For example, a first coil 3120a may be wound around a first drive unit connection portion 3212a, and a second coil 3120b may be wound around a second drive unit connection portion 3212b. In another example, the first drive unit connection portion 3212a may include a plurality of first drive unit connection portions spaced apart from each other, and the first coil 3120a may include a plurality of coil units arranged at the plurality of first drive unit connection portions. Furthermore, the second drive unit connection portion 3212b may include a plurality of second drive unit connection portions spaced apart from each other, and the second coil 3120b may include a plurality of coil units arranged at the plurality of second drive unit connection portions.

[0780] For example, the first connecting portion 3113a of the first winding frame 3110a can be connected to the second connecting hole 3151a formed in the inner portion 3512a of the first upper elastic member 5510a, and the first connecting portion 3113b of the second winding frame 3110b can be connected to the second connecting hole 3151b formed in the inner portion 3512b of the second upper elastic member 5510b.

[0781] The first connecting portion 3113a of the first winding frame 3110a may be formed by a recess in a portion of the upper surface of the first winding frame 3110a, and the first connecting portion 3113b of the second winding frame 3110b may be formed by a recess in a portion of the upper surface of the second winding frame 3110b.

[0782] In order to connect with the first upper elastic member 5510a and the second upper elastic member 5510b, each of the first connecting portion 3113a of the first winding frame 3110a and the first connecting portion 3113b of the second winding frame 3110b may contain an adhesive in itself.

[0783] The first connecting portion 3113a of the first winding frame 3110a may be formed at a position corresponding to the second connecting hole 3151a formed in the inner portion 3512a of the first upper elastic member 5510a. The first connecting portion 3113b of the second winding frame 3110b may be formed at a position corresponding to the second connecting hole 3151b formed in the inner portion 3512b of the second upper elastic member 5510b.

[0785] Furthermore, the first connecting portion 3113a or 3113b of each of the first winding frame 3110a and the second winding frame 3110b may be a recess. However, this disclosure is not limited thereto. In another embodiment, each connecting portion may be a protrusion or have a planar shape.

[0786] A second connecting portion (not shown) for connecting with the inner portion 3522a of the first lower elastic member 5520a may be formed on the lower surface of the first winding frame 3110a, and a second connecting portion (not shown) for connecting with the inner portion 3522b of the second lower elastic member 5520b may be formed on the lower surface of the second winding frame 3110b.

[0787] For example, the second connecting portion of the first winding frame 3110a can be connected to the third connecting hole 3161a formed in the inner portion 3522a of the first lower elastic member 5520a, and the second connecting portion of the second winding frame 3110b can be connected to the third connecting hole 3161b formed in the inner portion 3522b of the second lower elastic member 5520b.

The second connecting portion of the second winding frame 3110b can be formed in a shape corresponding to the shape of the third connecting hole 3161b formed in the inner portion 3522b of the second lower elastic member 5520b.

[0792] In another embodiment, at least one of the drive unit connection portion 3212a or 3212b, the first connection portion 3113a or 3113b, and the second connection portion can be omitted from each of the first winding frame 3110a and the second winding frame 3110b.

[0793] The first coil 3120a can be arranged at the first winding frame 3110a, and the second coil 3120b can be arranged at the second winding frame 3110b. For example, the first coil 3120a can be arranged on the outer surface of the first winding frame 3110a, and the second coil 3120b can be arranged on the outer surface of the second winding frame 3110b.

[0794] The first coil 3120a can be opposite to the first magnet unit 3130a, and the second coil 3120b can be opposite to the second magnet unit 3130b.

[0795] When a first drive signal (e.g., a first current) is provided to the first coil 3120a, the first coil 3120a and the first winding frame 3110a can move in the direction of the first optical axis (OA1) due to the electromagnetic interaction between the first coil 3120a and the first magnet unit 3130a.

[0796] Furthermore, when a second drive signal (e.g., a second current) is provided to the second coil 2120b, the second coil 3120b and the second winding frame 3120b can move in the direction of the second optical axis (OA2) due to the electromagnetic interaction between the second coil 3120b and the second magnet unit 3130b.

[0797] For example, the first coil 3120a can be a single integrated coil, and the second coil 3120b can be a single integrated coil.

[0798] In another example, the first coil 3120a may include a plurality of coil units spaced apart from each other, and the second coil 3120b may include a plurality of coil units spaced apart from each other.

[0799] For example, the first coil 3120a may include four coil units spaced apart from each other, and these four coil units may be arranged on the outer surface of the first winding frame 3110a such that the angle between two adjacent coil units is 90 degrees. Similarly, for example, the second coil 3120b may include four coil units spaced apart from each other, and these four coil units may be arranged on the outer surface of the second winding frame 3110b such that the angle between two adjacent coil units is 90 degrees.

[0800] The first coil 3120a may include a pair of first leads for providing a first power or a first drive signal, and the second coil 3120b may include a pair of second leads for providing a second power or a second drive signal.

[0801] For example, the pair of first leads of the first coil 3120a can be connected to the first upper elastic unit 3510a and the second upper elastic unit 3510b of the first upper elastic member 5510a. Furthermore, the pair of second leads of the second coil 3120b can be connected to the third upper elastic unit 3510c and the fourth upper elastic unit 3510d of the second upper elastic member 5510b.

[0802] The first coil 3120a can receive a first power or a first drive signal via the first upper elastic member 5510a, and the second coil 3120b can receive a second power or a second drive signal via the second upper elastic member 5510b.

[0803] For example, the first coil 3120a can receive a first power or a first drive signal via the circuit board 3250, the support member 3600 and the first upper elastic member 5510a, and the second coil 3120b can receive a second power or a second drive signal via the circuit board 3250, the support member 3600 and the second upper elastic member 5510b.

[0804] Reference Figure 28 The OIS moving part 5300 can receive at least a portion of the first AF moving part 5200a and the second AF moving part 5200b.

[0805] The OIS moving member 5300 can move the first AF moving member 5200a and the second AF moving member 5200b, or the OIS moving member 5300 can move together with the first AF moving member 5200a and the second AF moving member 5200b. The OIS moving member 5300 can move through interaction with the stator 5400.

[0806] The OIS moving part 5300 can be moved to perform the hand shake compensation function. When moving to perform the hand shake compensation function, the OIS moving part 5300 can move together with the AF moving parts 5200a and 5200b.

[0807] OIS moving part 5300 may include housing 3140 and magnet 3320. However, at least one of housing 3140 and magnet 3320 may be omitted from OIS moving part 5300 or may be changed.

[0814] For example, for OIS actuation, the outer surface of housing 3140 can be spaced apart from the inner surface of side plate 3302 of cover member 3300. In other words, for OIS actuation, housing 3140 can move in the space between housing 3140 and cover member 3300.

[0815] The upper elastic members 5510a and 5510b can be connected to the upper part, upper end or upper surface of the housing 3140, and the lower elastic members 5520a and 5520b can be connected to the lower part, lower end or lower surface of the housing 3140.

[0816] The housing 3140 can be integrally formed. That is, in this embodiment, the OIS moving member 1300 can be controlled individually, while the first moving member 5200a and the second AF moving member 5200b for AF drive can be controlled separately.

[0817] In other words, in this embodiment, the first lens module and the second lens module can move independently during AF driving and move together during OIS driving. This embodiment eliminates mutual interference between magnets in the dual VCN structure used for OIS.

[0818] In one embodiment, each of the housing 3140, the base 3210, and the circuit board 3250 may be integrally formed.

[0825] The inner surface of the first receiving unit 3011a formed by the first through hole can be positioned to be spaced apart from the outer surface of the first winding frame 3110a, and the inner surface of the second receiving unit 3011b formed by the second through hole can be positioned to be spaced apart from the outer surface of the second winding frame 3110b.

[0826] The first winding frame 3110a may have a first protruding portion or a first stop portion 3115a protruding outward from the outer surface of the first winding frame 3110a (see...). Figure 29 Furthermore, the second winding frame 3110b may have a second protruding portion or a second stop portion 3115b protruding outward from the outer surface of the second winding frame 3110b (see...). Figure 29 ).

[0827] The first protrusion 3115a of the first winding frame 3110a and / or the second protrusion 3115b of the second winding frame 3110b may contact the housing 3140 or the first recess 3146a formed on the upper surface of the housing 3140 (see...). Figure 30 The first winding frame 3110a and / or the second recessed portion 3146b serve as stops for mechanically restricting the movement of the first winding frame 3110a in the direction of the first optical axis (OA1) and for mechanically restricting the movement of the second winding frame 3110b in the direction of the second optical axis (OA2).

[0828] The connecting unit 3011c of the housing 3140 can be arranged between the first winding frame 3110a and the second winding frame 3110b.

In this structure, even if the damper 5700 coated on the connecting portions 3514a and 3514b of the upper elastic members 5510a and 5510b flows downward, the recessed portion 3319 of the housing 3140 can still receive the damper.

[0852] The housing 3140 may have a through hole 3147 in each corner or corner portion of the housing 3140, through which the support member 3600 extends. The through hole 3147 may be formed through at least a portion of each corner or corner portion of the housing 3140.

[0853] Magnet 3320 can be arranged at housing 3140. Magnet 3320 can be arranged outside the first coil 3120a and the second coil 3120b.

[0854] Magnet 3320 can be positioned opposite the first coil 3120a and the second coil 3120b in a direction perpendicular to the optical axes OA1 and OA2.

[0857] The magnet 3320 may include a first magnet unit 3130a disposed in a first receiving unit 3011a of the housing 3140 and a second magnet unit 3130b disposed in a second receiving unit 3011b of the housing 3140.

[0858] The first magnet unit 3130a can move the first winding frame 3110a in the direction of the first optical axis (OA1) by interacting with the first coil 3120a, and the second magnet unit 3130b can move the second winding frame 3110b in the direction of the second optical axis (OA2) by interacting with the second coil 3120b.

[0859] The first magnet unit 3130a may be arranged around the first winding frame 3110a and may be arranged opposite to the first coil 3120a. The second magnet unit 3130b may be arranged around the second winding frame 3110b and may be arranged opposite to the second coil 3120b.

[0864] In other words, when the magnet is located near the connecting unit 3011c of the housing 3140 at the side portions 3014d and 3015d of the housing 3140, errors may occur in the autofocusing operation of the first AF moving member and / or the autofocusing operation of the second AF moving member due to magnetic field interference between the magnets. This is because the distance between the magnets located at the side portions 3014d and 3015d of the housing 3140 is very small.
