Description

Technical Field

[0001] Embodiments relate to a lens driving device, and a camera module and an optical device including the same. Background Art

[0002] A voice coil motor (VCM) technology used in a conventional general camera module is difficult to apply to a miniature camera module intended to exhibit low power consumption, and research related thereto has been actively conducted.

[0003] The demand and production of electronic products such as smart phones and mobile phones equipped with cameras are increasing. The resolution of cameras for mobile phones is increasing and the size is decreasing, so their actuators are also becoming smaller, larger in diameter, and more functional. In order to realize high-resolution mobile phone cameras, improvements in the performance and additional functions of mobile phone cameras (e.g., auto focus, anti-shutter shake, and zoom in and out) are required.

[0077] Reference Figures 1 to 17 The lens driving device 100 may include a housing 140, a bobbin 110 disposed in the housing 140, an upper elastic member 150 combined with at least one of the housing 140 and the bobbin 110, a support member 220 combined with the upper elastic member 150 and supporting the housing 140, and a damper 87 disposed between the housing 140 and the support member 220 and including at least a portion combined with, in contact with, or attached to the housing 140 and the support member 220.

[0078] The lens driving device 100 may further include a first coil 120 and a magnet 130 to move the bobbin 110 in the optical axis direction. The lens driving device 100 may further include a lower elastic member 160 spaced apart from the upper elastic member 150 and combined with at least one of the housing 140 and the bobbin 110. The lens driving device 100 may further include a dummy member 11 disposed on the housing 140. The lens driving device 100 may include at least one of a base 210 and a cover member 300.

[0079] The lens driving device 100 may further include a first position sensor 170 for AF feedback driving and a sensing magnet 180. The lens driving device 100 may further include a capacitor 175 conductively connected to the first position sensor 170.

[0080] The lens driving device 100 may further include a second circuit board 250 conductively connected to the support member 220. The lens driving device 100 may include a second coil 230 corresponding to, facing or overlapping the magnet 130 to move the housing 140. The lens driving device 100 may further include a second position sensor 240 conductively connected to the second circuit board 250 for OIS feedback driving. The lens driving device 100 may further include a terminal member 27 conductively connected to the support member 220 and the second circuit board 250.

[0081] Reference Figures 1 to 3b , the bobbin 110 may be disposed inside the housing 140. For example, the bobbin 110 may be disposed in a hollow portion (or through hole) 140A of the housing 140.

[0082] The bobbin 110 may move in the optical axis direction or the first direction. For example, the bobbin 110 may move in the optical axis OA direction or the first direction (eg, Z-axis direction) through electromagnetic interaction between the first coil 120 and the magnet 130 .

[0083] The bobbin 110 may have an opening 25A for mounting the lens module 400. For example, the lens module 400 may include at least one of at least one lens and a lens barrel.

[0084] For example, the opening 25A of the wire barrel 110 may be in the form of a through hole penetrating the wire barrel 110 , and the shape of the opening of the wire barrel 110 may be circular, elliptical, or polygonal, but is not limited thereto.

[0085] The bobbin 110 may include first side portions 110a1 to 110a4 spaced apart from each other and second side portions 110b1 to 110b4 spaced apart from each other. Each of the second side portions 110b1 to 110b4 may connect two adjacent first side portions to each other. For example, the first side portions 110a1 to 110a4 of the bobbin 110 may be described as "side portions", and the second side portions 110b1 to 110b4 of the bobbin 110 may be described as "corner portions" or "corners".

[0086] A placement portion for placing the first coil may be provided on the side (or side) of the bobbin 110. For example, a first placement portion 41 for installing, placing or setting the first coil unit 120-1 may be provided on one of the sides of the bobbin 110 (e.g., the first side 110a1), and a second placement portion 42 for installing, placing or setting the second coil unit 120-2 may be provided on any other side of the side of the bobbin 110 (e.g., the second side 110a2).

[0087] For example, the first seating portion 41 and the second seating portion 42 may be disposed on both side portions 110 a 1 and 110 a 2 of the bobbin 110 disposed to each other.

[0088] Each of the first and second seating portions 41 and 42 may include at least one protrusion protruding from the outer surface of the bobbin 110 , but is not limited thereto. In another embodiment, each of the first and second seating portions may be in the form of a groove recessed from the outer surface of the bobbin 110 .

[0089] The first coil unit 120 - 1 may be combined with the first seating portion 41 , and the second coil unit 120 - 2 may be combined with or wound around the second seating portion 42 .

[0090] The bobbin 110 may include a groove for installing or setting the sensing magnet 180. For example, the bobbin 110 may include a groove 18a or a hole provided on another side (e.g., the third side 110a3) of the side thereof to install or set the sensing magnet 180. For example, the third side 110a3 of the bobbin 110 may be a side of the first coil unit 120-1 or the second coil unit 120-2 where the first coil 120 is not provided.

[0091] A protrusion 116 for placing the sensing magnet 180 may be formed on the third side portion 110a3 of the bobbin 110 so that it protrudes in a direction perpendicular to the optical axis. A groove 18a may be formed on the protrusion 116. For example, the groove 18a may be formed on the lower surface of the protrusion 116, but the present invention is not limited thereto. In another embodiment, the groove may be formed on at least one of the upper surface and the side surface of the protrusion 116. For example, the protrusion 116 may include an opening 17A to expose at least a portion of the sensing magnet 180.

[0092] Furthermore, similar to the protrusion 111 of the bobbin 110 , the protrusion 116 can suppress or prevent the bobbin 110 from rotating about the optical axis beyond a certain range.

[0093] The wire barrel 110 may include protrusions 111 provided at the corner portions 110b1 to 110b4. The protrusions 111 may protrude in a direction parallel to a straight line passing through the optical axis OA and perpendicular to the optical axis direction, but are not limited thereto.

[0094] The protrusion 111 of the bobbin 110 corresponds to the groove 145 of the housing 140 and may be inserted or disposed in the groove 145 of the housing 140 , and suppresses or prevents the bobbin 110 from moving or rotating beyond a certain range about the optical axis.

[0095] An escape groove 112a may be provided on the upper surface of the bobbin 110 to avoid spatial interference with the first frame connection portion 153 of the upper elastic member 150. A second escape groove 112b may be provided on the lower surface of the bobbin 110 to avoid spatial interference with the second frame connection portion 163 of the lower elastic member 160. For example, the first and second escape grooves 112a and 112b may be provided on the corner portions 110b1 to 110b4 of the bobbin 110, but are not limited thereto, and may be provided on at least one of the side portion and the corner portion of the bobbin 110.

[0096] The bobbin 110 may include a first stopper 114 protruding from an upper surface thereof. Figure 3b Although not shown in the drawings, the bobbin 110 may include a second stopper protruding from the lower surface 10B thereof.

[0097] When the wire drum 110 moves in the first direction for the automatic focusing function, even if the wire drum 110 moves beyond a specific range due to external impact, etc., the first stopper 114 and the second stopper 110 of the wire drum 110 can prevent the upper surface of the wire drum 110 from directly colliding with the inner side of the upper plate 301 of the cover member 300, and prevent the lower surface of the wire drum 110 from directly colliding with the second circuit board 250.

[0098] A first coupling portion 113 may be provided on the upper surface of the bobbin 110 to be engaged and fixed with the upper elastic member 150 , and a second coupling portion 117 may be provided on the lower surface 10B of the bobbin 110 to be coupled with the lower elastic member 160 .

[0099] For example, in Figure 3a and Figure 3b In the embodiment, the first and second coupling portions 113 and 117 of the bobbin 110 may be in a protrusion shape, but are not limited thereto, and in another embodiment, the first and second coupling portions of the bobbin 110 may be in a groove or plane shape.

[0100] In addition, when the first coil unit 120-1 and the second coil unit 120-2 are connected or combined with the upper elastic member 150 by a conductive adhesive member such as solder, the bobbin 110 may include guide grooves 9A to 9D formed on the upper surfaces of its two side portions 110a1 and 110a2 located on opposite sides of each other to prevent the first coil unit 120-1 and the second coil unit 120-2 from being separated from the bobbin and to guide the two ends of the first coil unit 120-1 and the second coil unit 120-2.

[0101] For example, one end of the first coil unit 120-1 may pass through the guide groove 9A and be combined with the third upper elastic member 150-3, and the other end of the first coil unit 120-1 may pass through the guide groove 9B and be combined with the first upper elastic member 150-1. In addition, for example, one end of the second coil unit 120-2 may pass through the guide groove 9C and be combined with the third upper elastic member 150-3, and the other end of the second coil unit 120-2 may pass through the guide groove 9D and be combined with the second upper elastic member 150-2.

[0102] Next, the first coil 120 will be described.

[0103] The first coil 120 may be disposed on the bobbin 110 or may be combined with the bobbin 110 .

[0104] The first coil 120 includes a first coil unit 120-1 and a second coil unit 120-2 disposed on two opposite sides (eg, 110a, 110b) of the bobbin 110. Here, the coil unit may be expressed as a "coil portion", "coil block" or "coil ring".

[0105] For example, the first coil unit 120 - 1 may be disposed at or combined with the first seating portion 41 of the bobbin 110 , and the second coil unit 120 - 2 may be disposed at or combined with the second seating portion 42 of the bobbin 110 .

[0106] Each of the first coil unit 120-1 and the second coil unit 120-2 may include at least one of an elliptical shape and a closed curve shape. For example, each of the first coil unit 120-1 and the second coil unit 120-2 is in the form of a coil ring that is rotated and wound around an axis that passes through the center of the opening 25A of the bobbin 110 and is perpendicular to the optical axis OA.

[0107] For example, each of the first coil unit 120-1 and the second coil unit 120-2 includes a first portion 3a, a second portion 3b disposed below the first portion 3a, and a connecting portion 3c connecting the first portion 3a and the second portion 3b, and a closed curve may be formed by the first portion 3a, the second portion 3b, and the third portion 3c. For example, each of the first coil unit 120-1 and the second coil unit 120-2 may include a central hole 3d.

[0108] The third portion 3c includes a first connection portion 3c1 connecting one end of the first portion 3a and one end of the second portion 3b and a second connection portion 3c2 connecting the other end of the first portion 3a and the other end of the second portion 3b.

[0109] For example, the first portion 3a may be represented as a "first straight portion", the second portion 3b may be represented as a "second straight portion", and the third portion 3c may be represented as a "curved portion", the first connecting portion 3c1 may be represented as a first curved portion, and the second connecting portion 3c2 may be represented as a second curved portion.

[0110] For example, the first coil unit 120-1 and the second coil unit 120-2 may be connected in series. For example, the first coil unit 120-1 and the second coil unit 120-2 may be connected in series with each other through the upper elastic member 160, but is not limited thereto. The two coil units may be connected in series with each other through at least one of the upper elastic member and the lower elastic member.

[0111] In another embodiment, the first coil unit and the second coil unit may be connected in series with each other via a connecting coil or a connecting portion. For example, one end of the connecting coil may be directly connected to one end of the first coil unit, and the other end of the connecting coil may be connected to one end of the second coil unit.

[0112] In another embodiment, the first coil unit 120 - 1 and the first coil unit 120 - 2 may be conductively separated from each other or spaced apart from each other and may be driven individually.

[0113] In another embodiment, the first coil may have a closed curve, for example, a ring shape, wound around the outer circumferential surface of the bobbin 110 with respect to the optical axis (or the central axis).

[0114] When a driving signal (e.g., a driving current) is provided to the first coil 120, an electromagnetic force may be formed by the electromagnetic interaction between the first coil 120 and the magnet 130, and the bobbin 110 may be moved in the optical axis direction OA by the electromagnetic force. For example, the bobbin 110 may be moved by the electromagnetic force between the first coil unit 120-1 and the first magnet unit 130-1 and the electromagnetic force between the second coil unit 120-2 and the second magnet unit 130-2.

[0115] Depending on the initial position of the AF movable unit, the bobbin 110 can move in an upward or downward direction (e.g., Z-axis direction), which is referred to as bidirectional driving of the AF movable unit. Alternatively, at the initial position of the AF movable unit, the bobbin 110 can move in an upward direction, which is referred to as unidirectional driving of the AF movable unit.

[0116] In the initial position of the AF movable unit, the first coil unit 120-1 may face or overlap the first magnet unit 130-1 in the first horizontal direction 201, but may not face or overlap the third magnet unit 130-3. For example, the first horizontal direction may be a direction perpendicular to the optical axis OA and from the optical axis OA toward the first coil unit 120-1.

[0117] In the initial position of the AF movable unit, the second coil unit 120 - 2 may face or overlap the second magnet unit 130 - 2 in the first horizontal direction, but may not face or overlap the third magnet unit 130 - 3 .

[0118] The AF movable unit may include the bobbin 110 and a component combined with the bobbin 110. For example, the AF movable unit may include the bobbin 110, the first coil 120, and the sensing magnet 180. In addition, the AF movable unit may further include a lens module 400 mounted on the bobbin 110.

[0119] Also, the initial position of the AF movable unit is the initial position of the AF movable unit in a state where power is not supplied to the first coil 120, or the position where the AF operating unit is located due to elastic deformation of the upper elastic member 150 and the lower elastic member 160 only due to the weight of the AF operating unit.

[0120] In addition, the initial position of the bobbin 110 may be a position where the AF operation unit is located when gravity acts in a direction from the bobbin 110 toward the base 210 or when gravity acts in a direction from the base 210 toward the bobbin 110 .

[0121] The sensing magnet 180 provides a magnetic field for sensing by the first position sensor 170. The sensing magnet 180 may be disposed on the bobbin or combined with the bobbin 110. For example, the sensing magnet 180 may be disposed on the protrusion 116 of the bobbin 110. For example, the sensing magnet 180 may be combined with the protrusion 116 of the bobbin 110. For example, at least a portion of the sensing magnet 180 may be disposed in the groove 18a of the protrusion 116, and may be combined with the groove 18a using an adhesive or the like. The sensing magnet 180 may be disposed to correspond to or face the first position sensor 170 in the optical axis direction OA.

[0122] At least a portion of one side (e.g., the lower surface) of the sensing magnet 180 corresponding to the first position sensor 170 may be exposed to the outside of the groove 18a of the bobbin 110, but is not limited thereto. In another embodiment, the side of the sensing magnet 180 facing the first position sensor 170 may not be exposed from the bobbin 110.

[0123] For example, the boundary surface of the N pole and the S pole of the sensing magnet 180 disposed on the bobbin 110 may be parallel to the direction perpendicular to the optical axis OA. For example, the N pole and the S pole of the sensing magnet 180 may face each other in the optical axis direction, but is not limited thereto.

[0124] In another embodiment, the sensing magnet may be disposed such that its N pole and S pole face each other in a direction perpendicular to the optical axis. For example, in another embodiment, the boundary surface between the N pole and S pole of the sensing magnet 180 disposed on the bobbin 110 may be parallel to the optical axis OA.

[0125] For example, the sensing magnet 180 may be a monopolar magnet having one N pole and one S pole, but is not limited thereto. In another embodiment, the sensing magnet 180 may be a bipolar magnet or a quadrupole magnet including two N poles and two S poles.

[0126] For example, the sensing magnet 180 includes a first magnet portion having an N pole and an S pole, a second magnet portion having an S pole and an N pole, and a partition wall disposed between the first magnet portion and the second magnet portion. For example, the partition wall may be a "non-magnetic partition wall". For example, the first magnet portion may be disposed on the second magnet portion, and the N pole (or S pole) of the first magnet portion may be disposed to face the S pole (or N pole) of the second magnet portion. For example, the first magnet portion and the second magnet portion may be located on opposite sides of each other in the optical axis direction in a state where a partition portion is disposed between them, and may be arranged so that opposite polarities face each other. For example, the length in the optical axis direction of the first magnet portion may be different from the length in the optical axis direction of the second magnet portion. For example, the length in the optical axis direction of the first magnet portion may be greater than the length in the optical axis direction of the second magnet portion. In another embodiment, the length in the optical axis direction of the first magnet portion may be less than or equal to the length in the optical axis direction of the second magnet portion.

[0127] For example, by changing the optical axis length of the N / S pole of the first magnet portion and the optical axis length of the S / N pole of the second magnet portion of the sensing magnet 180, the magnetic field value (or magnetic force) detected by the position sensor 170 can have an N pole (+), an S pole (-), or a mixture of N and S poles.

[0128] For example, the contents described later regarding the magnet 130 implemented as a dipole magnet may be applied or applied by analogy to a sensing magnet.

[0129] The shape of the sensing magnet 180 may be a cylinder, a column, a semi-cylindrical shape, or a polyhedron (eg, a hexahedron), but is not limited thereto.

[0130] For example, the length of the sensing magnet 180 in the optical axis direction may be greater than the length of the sensing magnet 180 in the direction perpendicular to the optical axis. In another embodiment, the length of the sensing magnet 180 in the optical axis direction may be equal to or less than the length in the direction perpendicular to the optical axis.

[0131] When the sensing magnet 180 has a cylindrical or cylindrical shape, the magnetic field distribution of the sensing magnet 180 detected by the first position sensor 170 may be uniform, which may improve the sensitivity of the first position sensor 170 .

[0132] For example, the cross-sectional shape of the sensing magnet 180 cut in a direction perpendicular to the optical axis may be circular, elliptical, or polygonal (eg, triangular or square).

[0133] In another embodiment, the first position sensor may be provided on the bobbin 110 , and the sensing magnet may be provided on the housing 140 to correspond to, face, or overlap the first position sensor in a direction perpendicular to the optical axis.

[0134] In another embodiment, the sensing magnet may be disposed on the bobbin 110 , and the first position sensor may be disposed on the base 210 to correspond to, face, or overlap the sensing magnet in the optical axis direction.

[0135] In another embodiment, the sensing magnet may be disposed on the second circuit board 250 or the base 210 , and the first position sensor may be disposed on the bobbin 110 .

[0136] In another embodiment, the lens driving device 100 may include a balancing magnet disposed on the bobbin 110 to offset the magnetic field influence of the sensing magnet 180 and balance the weight of the sensing magnet 180. For example, the balancing magnet may be disposed opposite to the sensing magnet 180 based on the optical axis.

[0137] Reference Figures 4a to 4c The housing 140 accommodates at least a portion of the bobbin 110 therein. The housing 140 is configured to support the magnet 130. For example, the housing 140 may support the magnet units 130-1 to 130-3 of the magnet 130 and the dummy member 11.

[0138] The housing 140 may be denoted as an “OIS movable unit”. The OIS movable unit may be moved together with the AF movable unit by an electromagnetic force generated by the interaction between the magnet 130 and the second coil 230. For example, the housing 140 may be disposed inside the cover member 300. For example, the housing 140 may be disposed between the cover member 300 and the bobbin 110.

[0139] The outer surface of the housing 140 may be spaced apart from the inner surface of the side plate 302 of the cover member 300. Since there is a separation space between the housing 140 and the cover member 300, the housing 140 may move in a direction perpendicular to the optical axis by the electromagnetic force between the magnet 130 and the second coil 230.

[0140] The housing 140 may include an opening or hollow portion 140A. For example, the housing may have a hollow cylindrical shape. For example, the housing may have a polygonal (eg, square or octagonal) or circular opening 140A.

[0141] The housing 140 may include a side portion and a corner portion. For example, 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. For example, the housing 140 may include a first side portion 141-1 to a fourth side portion 141-4 and a first corner portion 142-1 to a fourth corner portion 142-4. For example, the first side portion 141-1 to the fourth side portion 141-4 may be spaced apart from each other. Each of the corner portions 142-1 to 142-4 of the housing 140 may be disposed on or between two adjacent side portions, and the side portions 141-1 to 141-4 may be connected.

[0142] For example, the corner portions 142-1 to 142-4 may be located at corner portions or edges of the housing 140. For example, the number of side portions of the housing 140 is four and the number of corner portions is four, but the number is not limited thereto.

[0143] Each of the side portions 141 - 1 to 141 - 4 of the housing 140 may be disposed in parallel with a corresponding one of the side plates 302 of the cover member 300 .

[0144] 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, but is not limited thereto. For example, the first side portion 141-2 and the second side portion 141-2 of the housing 140 may be disposed opposite to each other, and the third side portion 141-3 and the fourth side portion 141-4 may be disposed opposite to each other. Each of the third side portion 141-3 and the fourth side portion 141-4 of the housing 140 may be located between the first side portion 141-2 and the second side portion 141-2.

[0145] In order to prevent the cover member 300 from directly colliding with the inner surface of the upper plate 301, the housing 140 may include a stopper 144 disposed on an upper portion, an upper end or an upper surface thereof. For example, the stopper 144 may protrude upward from the upper surface of the housing 140 and may be disposed or arranged on at least one of the side and corner portions of the housing 140.

[0146] In addition, the housing 140 may include protrusions 61 or steps provided on the corner portions 142-1 to 142-4 of the housing 140 to guide the damper 88 (see FIG. 14A ) contacting the upper elastic member 150. Fig.18 ) placement and prevents damper 88 from overflowing.

[0147] The housing 140 may include at least one first coupling portion 143 disposed or formed on an upper portion, an upper end portion, or an upper surface thereof and coupled with the upper elastic member 150 (eg, the first outer frame 152 ).

[0148] In addition, the housing 140 may include at least one second coupling portion 148 disposed or formed on a lower portion, a lower end, or a lower surface thereof and coupled and fixed to the lower elastic member 160 (eg, the second outer frame 162 ).

[0149] For example, the first coupling portion 143 of the housing 140 may be a protrusion, but in another embodiment, the first coupling portion may be a groove or a flat surface. For example, the second coupling portion 148 of the housing 140 may be a groove, but in other embodiments, it may be a protrusion or a flat surface.

[0150] For example, the first coupling portion 143 of the shell 140 and the hole 152a of the first outer frame 152 of the upper elastic member 150 can be coupled using heat welding or an adhesive, and the second coupling portion 148 of the shell 140 and the hole 162a of the second outer frame 162 of the lower elastic member 160 can be coupled using heat welding or an adhesive.

[0151] The housing 140 may include a placement portion for placing or arranging the magnet 130. For example, the housing 140 may include a first placement portion 141a and a second placement portion 141b, the first placement portion 141a being disposed at one of two side portions disposed opposite to each other (e.g., the first side portion 141-1) for placing the first magnet unit 130-1, and the second placement portion 141b being disposed at the other of the two side portions (e.g., 141-2) for placing the second magnet unit 130-2. For example, the housing 140 may include a third placement portion 141c and a fourth placement portion 141d, the third placement portion 141c being disposed at one of the other two side portions (e.g., the fourth side portion 141-4) for placing the third magnet unit 130-3, and the fourth placement portion 141d being disposed at the other of the other two side portions (e.g., 141-3) for placing the dummy member 11.

[0152] Each of the first to third seating portions 141a to 141c of the shell 140 may be disposed on an inner side surface of a corresponding one of the side portions of the shell 140, but is not limited thereto. In another embodiment, it may be disposed on an outer side surface of a corresponding one of the side portions of the shell 140.

[0153] Each of the first to third seating portions 141 a to 141 c of the housing 140 is formed as a groove having a shape corresponding to or matching a corresponding one of the first to third magnets 130 - 1 to 130 - 3 , but is not limited thereto.

[0154] For example, the first placement portion 141a (or the second placement portion 141b) of the housing 140 may have a first opening facing the first coil unit 120-1 and a second opening exposing the lower portion or lower end of the first magnet unit 130-1. For example, the second placement portion 141b of the housing 140 may have a first opening facing the second coil unit 120-2 and a second opening exposing the lower portion or lower end of the second magnet unit 130-2. In addition, for example, the third placement portion 141b of the housing 140 has a first opening opening toward the outer surface of the bobbin 110 and a second opening exposing the lower portion and lower end of the third magnet unit 130-3. In another embodiment, each of the first to third placement portions of the housing 140 may include at least one of the first opening and the second opening.

[0155] For example, a side surface of at least one of the first to third magnet units 130-1 to 130-3 may be exposed from the outer side surface of the housing 140. For example, the first magnet unit 130-1 and the second magnet unit 130-2 may not be exposed to the outer side surface of the housing 140, but the third magnet unit 130-3 may be exposed to the outer side surface of the housing 140. Fig.11 As shown, the width W2 of the third magnet unit 130-3 may be greater than the width of each of the first magnet unit 130-1 and the second magnet unit 130-2, and by exposing the third magnet 130-3 from the side of the housing 140 where the third magnet unit 130-3 is disposed, the size of the housing 140 may be avoided from being increased.

[0156] A length W2 of the third magnet unit 130 - 3 in the width direction may be greater than a length W1 of the first magnet unit 130 - 1 in the width direction or / and a length of the second magnet unit 130 - 2 in the width direction ( W2 > W1 ).

[0157] In another embodiment, the first to third magnet units may not be exposed to the outer side of the housing 140 .

[0158] The fourth seating portion 141d of the housing 140 may include at least one seating portion for mounting the dummy member 11. For example, the fourth seating portion 141d may include two seating portions on which the two dummy members 11A and 11B are disposed.

[0159] For example, a lower end or a lower surface of at least one of the first to third magnet units 130 - 1 to 130 - 4 and the dummy member 11 may protrude in a direction from the lower surface of the housing 140 toward the second circuit board 250 .

[0160] At least a portion of the dummy member 11 fixed to or disposed on the seating portion 141d of the housing 140 may be exposed to the outside of the housing 140. For example, the lower end of the dummy member 11 may be exposed to the outside of the seating portion 141d of the housing 140. For example, the lower end or lower surface of the dummy member 11 may protrude from the lower surface of the housing 140 toward the second circuit board 250. For example, the first to third magnet units 130-1 to 130-3 and the dummy member 11 may be fixed to the seating portions 141a to 141d by an adhesive.

[0161] The support members 220-1 to 220-4 may be provided at the corners 142-1 to 142-4 of the housing 140. The corners 142-1 to 142-4 of the housing 140 may include holes 147 through which at least a portion of the support members 220-1 to 220-4 pass. In another embodiment, the support members may be provided at the sides of the housing 140.

[0162] For example, the housing 140 may include a hole 147 penetrating through upper portions of the corner portions 142 - 1 to 142 - 4 .

[0163] At least one of the support members 220-1 to 220-4 may be provided at least one of the corner portions 142-1 to 142-4 of the housing 140. For example, at least one support member may be provided at each of the corner portions 142-1 to 142-4 of the housing 140. For example, two support members 20A and 20B may be provided at each of the corner portions 142-1 and 142-4 of the housing 140, and two holes 147A and 147B may be formed at each corner portion of the housing 140.

[0164] For example, the hole 147 may be a through hole that penetrates the housing 140 in the optical axis direction. For example, at least a portion of the support member 220 may penetrate the hole 147 of the housing 140. One end of the support member 220 may be connected or joined to the upper elastic member 150 by solder or conductive adhesive 902. For example, an edge of one end of the support member 220 may protrude from the solder 902 (see Fig.21 In another embodiment, the end of one end of the support member 220 may be located inside the solder 902 and may not protrude outside the solder 902 .

[0165] For example, in order to easily apply the damper, the diameter of the hole 147 may gradually increase in a direction from the upper surface of the housing 140 to the lower surface of the housing 140, but is not limited thereto, and in another embodiment, the diameter of the hole 147 may be uniform.

[0166] In another embodiment, the hole 147 of the housing 140 may include an opening partially open to the outside (or the outer side of the housing 140). In another embodiment, the housing 140 may include a groove or an escape portion for the support member 220 to pass through instead of the hole 147.

[0167] In another embodiment, the hole may be recessed from the outer side of the corner portion of the housing 140, and at least a portion of the hole may be open to the outer side of the corner portion. The number of holes 147 in the housing 140 may be equal to the number of support members.

[0168] The housing 140 may include at least one stopper 149 protruding from the outer side of the side portions 141-1 to 141-4, and the at least one stopper 149 may be configured to prevent the outer side of the housing 140 from directly colliding with the cover member 300 when the housing 140 moves in a direction perpendicular to the optical axis direction.

[0169] The housing 140 may include a groove 145 formed at a position corresponding to the protrusion 111 of the bobbin 110. For example, the groove 145 may be formed at the inner surface of at least one of the corner portions 142-1 to 142-4 of the housing 140. The groove portion 145 may be open at the top, and the groove portion 145 may have an opening formed at one side facing the outer surface of the corner portion of the bobbin 110.

[0170] The housing 140 may include a groove 14A (or placement groove) for placing or accommodating the circuit board 190. The housing 140 may include a groove 14B (or placement groove) for placing or accommodating the first position sensor 170. The groove 14A of the housing 140 may be disposed on any one of the sides 141-1 to 141-4 of the housing 140 (e.g., 141-3). For example, in order to facilitate the installation of the circuit board 190, the groove 14A of the housing 140 may be open at the top and have an opening open to the inner side of the housing 140. The groove 14B of the housing 140 may be disposed on the inner side of the third side 143-2 of the housing 140 and may be connected or communicated with the groove 14A. For example, a capacitor 174 may be disposed in the groove 14B of the housing 140.

[0171] Reference Figure 5a , the housing 140 may include a protrusion 70 protruding from the outer side surface 62A of the corner portions 142-1 to 142-4 in a direction perpendicular to the optical axis. For example, the protrusion 70 may be provided at each corner portion of the housing 140. For example, the protrusion 70 may protrude in a direction perpendicular to the optical axis and from the optical axis toward the corner portions 142-1 to 142-4 of the housing 140 (e.g., a diagonal direction).

[0172] For example, when viewed in the optical axis direction or from the top, the shape of the protrusion 70 may be a polygon, such as a trapezoid. For example, when viewed in the optical axis direction or from the top, the horizontal length of the protrusion 70 may decrease in the diagonal direction.

[0173] The protrusion 70 may include a hole 147 through which at least a portion of the support member 220 passes. The hole 147 may be a through hole that penetrates the protrusion 70 in the optical axis direction.

[0174] For example, the number of holes 147 may be equal to the number of support members 220 provided at each corner portion of the housing 140. For example, the protrusion 70 may include two holes 147A and 147B spaced apart from each other. In another embodiment, the protrusion 70 may include one hole, and the two support members may be arranged to be spaced apart from each other in the one hole.

[0175] For example, the protrusion 70 may include a recess 65 for accommodating the damper 87. For example, the recess 65 may be recessed from the upper surface 60B of the protrusion 70. For example, the recess 65 may include a bottom surface 65A having a step from the upper surface 60B of the protrusion 70 and a side surface 65B disposed between the bottom surface 65A and the upper surface 60B of the protrusion 70 and connecting the bottom surface 65A and the upper surface 60B of the protrusion 70.

[0176] For example, the hole 147 may be disposed within the recess 65 of the protrusion 70. For example, the hole 147 may be formed in the bottom surface 65A of the recess 65 of the protrusion 70. For example, the hole 147 may penetrate the bottom surface 65A of the recess 65 of the protrusion 70.

[0177] In another embodiment, the protrusion 70 may not include the recess 65 , and the damper 87 may be provided on the upper surface 60B of the protrusion 70 .

[0178] The housing 140 may include a first surface 60A to which the upper elastic member 150 (e.g., the first outer frame 152 or the first coupling portion 91) contacts, is attached, or is coupled. For example, the first coupling portion 143 may be formed on the first surface 60A of the housing 140. For example, the first coupling portion 143 may protrude from the first surface 60A of the housing 140. For example, the stopper 144 may be formed on the first surface 60A of the housing 140. For example, the stopper 144 may protrude from the first surface 60A of the housing 140. For example, the first surface 60A may be set lower than the upper surface of the first coupling portion 113, the upper surface of the stopper 144, and the upper surface of the upper elastic member 150.

[0179] For example, the housing 140 may include a second surface 60B disposed lower than the first surface 60B. For example, the second surface may be an upper surface 60B of the protrusion 70. Alternatively, in another embodiment, the second surface of the housing 140 may be a bottom surface 65A of the protrusion 70.

[0180] For example, the first surface 60A and the second surface 60B of the housing 140 may be disposed or formed on the corner portions 142-1 to 142-4 of the housing 140. For example, the first surface 60A of the housing 140 may have the same height as the upper surfaces of the side portions 141-1 to 141-4 of the housing 140. In another embodiment, the first surface 60A of the housing 140 may be disposed lower or higher than the upper surfaces of the side portions 141-1 to 141-4 of the housing 140.

[0181] For example, there may be a step between the first surface 60A and the second surface 60B in the optical axis direction. For example, the second surface 60B may be located below the first surface 60A. For example, the second surface 60B may be arranged to be lower than the first surface 60A. In addition, the first surface 60A may be arranged to be closer to the center or the optical axis OA of the housing 140 than the second surface 60B. The second surface 60B may be located outside the first surface 60A.

[0182] The housing 140 may include a third surface 60C disposed lower than the first surface 60A and higher than the second surface 60B. For example, the third surface 60C may be disposed or formed on the corner portions 142 - 1 to 142 - 4 of the housing 140 .

[0183] The third surface 67C may be located between the first surface 60A and the second surface 60B. For example, among the first surface 60A to the third surface 60C, the first surface 60A may be disposed closest to the center or optical axis of the housing 140, the second surface 60B may be disposed farthest from the center or optical axis of the housing 140, and the third surface 60C may be located in the middle of the first surface 60A and the second surface 60B.

[0184] A damper 88 in contact with, attached to, or combined with the upper elastic member 150 (e.g., the first outer frame 152 or the connecting portion 93) may be provided on the third surface 60C. The housing 140 may include a protrusion 61 (or a guide protrusion) protruding from the third surface 60C. For example, the protrusion 61 may be provided at an edge of the third surface 60C. For example, the protrusion 61 may be used to prevent the damper 88 from overflowing to the outside of the outer side surface of the housing 140.

[0185] Reference Figure 5a , the housing 140 includes a first side surface 62A located between the second surface 60B and the third surface 60C and connecting the second surface 60B and the protrusion 61. In an embodiment where the protrusion 61 is omitted, the first side surface 62A of the housing 140 may connect the second surface 60B and the third surface 60C.

[0186] Reference Figure 5b , the protrusion 70 may include a lower surface 60D opposite to the upper surface 60B. In addition, the housing 140 includes a second side surface 62B located between the lower surface 60D of the protrusion and the lower surface 80A of the housing 140 and connecting the lower surface 60D of the protrusion 70 and the lower surface 80A of the housing 140. The first side surface 62A and the second side surface 62B of the housing 140 may have a step in the diagonal direction. The second side surface 62B may be arranged closer to the optical axis OA than the first side surface 62A.

[0187] Reference Figure 5bThe housing 140 may include a fourth surface 80A to which the lower elastic member 160 (eg, the second outer frame 162) contacts, is attached or combined. The fourth surface 80A may be located below the first surface 60A, the second surface 60B, and the third surface 60C of the housing 140.

[0188] For example, the upper surface of the housing 140 may include the first surface 60A and the second surface 60B of the housing 140. Or, for example, the lower surface of the housing 140 may include the fourth surface 80A of the housing 140. In another embodiment, the third surface 60C of the housing 140 may be omitted.

[0189] For example, the protrusion 70 may overlap the second coupling portion 92 of the upper elastic member 150 in the optical axis direction or the first direction. For example, the protrusion 70 may overlap at least a portion of the connection portion 93 of the upper elastic member 150 in the optical axis direction or the first direction.

[0190] The magnet 130 may be disposed at the housing 140 or coupled to the housing 140 .

[0191] The magnet 130 may include a plurality of magnet units.

[0192] For example, the magnet 130 may include first, second, and third magnet units 130-1, 130-2, and 130-3 disposed spaced apart from each other on the housing 140. For example, each of the first to third magnet units 130-1 to 130-3 may be disposed between the bobbin 110 and the housing 140.

[0193] For example, the first magnet unit 130-1, the second magnet unit 130-2, and the third magnet unit 130-3 may be disposed on the side of the housing 140. For example, the first magnet unit 130-1 and the second magnet unit 130-2 are disposed on two sides 141-1 and 141-2 that are opposite to each other among the sides 141-1 to 141-4 of the housing 140. For example, the third magnet unit 130-3 may be disposed on one side of the housing 140 where the first magnet unit 130-1 and the second magnet unit 130-2 are not disposed. For example, the third magnet unit 130-3 may be disposed on the fourth side 141-4 of the housing 140.

[0194] Since the first coil unit 120-1 and the second coil unit 120-2 for AF driving are disposed on two sides of the bobbin 110 facing each other, no coil unit for AF driving may be disposed between the bobbin 110 and the third magnet unit 130-3. In addition, no coil unit for AF driving may be disposed between the bobbin 110 and the dummy member 11.

[0195] In addition, for OIS driving, the first to third coil units 230 - 1 to 230 - 3 of the second coil 230 and the first to third magnet units of the magnet 130 may correspond to, face, or overlap each other, and the second coil 230 may not be disposed between the dummy member 11 and the base 210 .

[0196] In another embodiment, the first magnet unit and the second magnet unit can be arranged on two corner portions of the shell 140 opposite to each other, and the third magnet unit can be arranged on one of the other two corner portions of the shell 140 opposite to each other, and the dummy component can be arranged on the other corner portion of the other two corner portions.

[0197] Another embodiment may include a magnet mounting member. The magnet mounting member may be provided separately from the housing 140, but is not limited thereto, and in other embodiments, may be integrally formed with the housing 140.

[0198] For example, the magnet mounting member may be in the form of a frame, the frame may be coupled with the housing 140 , and the magnet 130 may be mounted or coupled to the frame.

[0199] In the initial position of the AF movable unit, the magnet 130 is disposed on the housing 140 such that at least a portion of the magnet 130 overlaps the first coil 120 in a direction parallel to a straight line perpendicular to and passing through the optical axis OA.

[0200] Each of the first to third magnet units 130-1 to 130-3 may be in the shape of a polyhedron (e.g., a hexahedron). For example, each of the first to third magnet units may have a cross-sectional shape in a direction perpendicular to the optical axis, such as a triangle, square, pentagon, rhombus, or trapezoid, but is not limited thereto.

[0201] Each of the first to third magnet units 130-1 to 130-3 may be a monopolar magnet, but is not limited thereto. In another embodiment, each of the first to third magnet units 130-1 to 130-3 may be a bipolar magnet or a quadrupole magnet including two N poles and two S poles.

[0202] For example, the sensing magnet 180 may not overlap with the first coil 120 in the optical axis direction. In another embodiment, the sensing magnet may overlap with the first coil 120 in the optical axis direction.

[0203] The dummy member 11 may be disposed corresponding to or facing the third magnet unit 130-3 on the housing 140. The dummy member 11 may alternatively be expressed as a "weight balancing member," "balancing member," "weight compensating member," or "weight member."

[0204] For example, the dummy member 11 may be disposed on the third side portion 141 - 3 of the housing 140 .

[0205] The dummy member 11 may be made of a material that is not affected by a magnet, may be made of a non-magnetic material, or may be a non-magnet, but is not limited thereto. In another embodiment, the dummy member 11 may be a magnetic material or may include a magnet.

[0206] The dummy member 11 serves to balance the weight of the three magnet units 130 - 1 to 130 - 4 provided on the housing 140 .

[0207] For example, the dummy member 11 may have the same mass as the third magnet unit 130 - 3 In another embodiment, the weight of the dummy member 11 may have an error with the weight of the third magnet unit 130 - 3 within a range causing an OIS operation error due to weight imbalance.

[0208] The dummy component 11 may include at least one dummy portion 11A and 11B. For example, the dummy component 11 may include one dummy portion or two or more dummy portions. For example, the dummy component 11 may include a first dummy portion 11A and a second dummy portion 11B that are spaced apart from each other.

[0209] For example, at least a portion of the protrusion 111 of the bobbin 110 may be disposed between the first dummy portion 11A and the second dummy portion 11B. Alternatively, for example, at least a portion of the sensing magnet 180 may be disposed between the first dummy portion 11A and the second dummy portion 11B.

[0210] For example, the first dummy portion 11A and the second dummy portion 11B may have symmetrical shapes or the same shape and may be symmetrically arranged with respect to the sensing magnet 180. In another embodiment, the first dummy portion 11A and the second dummy portion 11B may be asymmetrically arranged with respect to the sensing magnet 180.

[0211] At least a portion of the dummy member 11 may overlap the third magnet unit 130 - 3 in a direction perpendicular to the optical axis and from the third corner portion 142 - 3 of the housing 140 to the fourth corner portion 142 - 4 of the housing 140 .

[0212] For example, the dummy member 11 may not overlap with the second coil 230 in the optical axis direction. Since the dummy member 11 does not affect the OIS driving, the lens driving device may not include a coil unit corresponding to the dummy member.

[0213] For example, when the dummy member 11 includes a magnetic material, the magnetic strength of the dummy member 11 may be less than the magnetic strength of the third magnet unit 130-3. For example, the dummy member 11 may include tungsten, and tungsten may account for more than 95% of the total weight, but is not limited thereto. For example, the dummy member 11 may be a tungsten alloy.

[0214] For example, the dummy member 11 may have a polyhedral shape, such as a cuboid. In other embodiments, it may be formed into various shapes capable of weight compensation. For example, the dummy member 11 may include a rounded portion or a curved surface at its side edge.

[0215] The housing 140 may include a groove 14B to avoid spatial interference with the sensing magnet 180, the protrusion 116 of the bobbin 110, and the first position sensor 170. For example, the groove 14B may be formed on the inner surface of the third side portion 141-3 of the housing 140. In addition, the groove 14B may be located between the first dummy portion 11A and the second dummy portion 11B.

[0216] Figures 11 to 13 For example, each of the first magnet unit 130-1 and the second magnet unit 130-2 includes a first magnet portion 33A, a second magnet portion 33B, and a partition wall 33C disposed between the first magnet portion 33A and the second magnet portion 33B. Here, the partition wall 33C may alternatively be expressed as a "non-magnetic barrier wall". The partition wall 33C is configured to separate or isolate the first magnet portion 33A and the second magnet portion 33B, and may be a portion that is substantially non-magnetic and has almost no polarity. For example, the partition wall 33C may be made of a non-magnetic material, air, or the like. The non-magnetic partition wall may be expressed as a "neutral zone" or a "neutral region"

[0217] For example, the second magnet unit 130-2 may have the same structure as the first magnet unit 130-1, and the description of the first magnet unit 130-1 may be applicable or applicable by analogy to the second magnet unit 130-2. In another embodiment, each of the first magnet unit 130-1 and the second magnet unit 130-2 may be a unipolar magnetized magnet including one N pole and one S pole.

[0218] The third magnet unit 130-3 may be a monopolar magnet including one N pole and one S pole. In another embodiment, the third magnet unit 130-3 may be a bipolar magnet including a first magnet portion, a first magnet portion, and a partition wall disposed between the first magnet portion and the first magnet portion.

[0219] When viewed from the top side, the first magnet unit 130 - 1 may be located inside a region of the first coil unit 230 - 1 , and may overlap with the first coil unit 230 - 1 in the optical axis direction.

[0220] When viewed from the top side, the second magnet unit 130-2 may be located inside the region of the second coil unit 230-2 and may overlap with the second coil unit 230-2 in the optical axis direction.

[0221] When viewed from the top side, the third magnet unit 130-3 may be located inside the region of the third coil unit 230-3 and may overlap with the third coil unit 230-3 in the optical axis direction.

[0222] For example, the first magnet unit 130-1 and the second magnet unit 130-2 may have the same length, width, and height. In another embodiment, the first magnet unit 130-1 and the second magnet unit 130-2 may have different lengths, widths, or heights.

[0223] In addition, for example, the first coil unit 230-1 and the second coil unit 230-2 may have the same length, width, and height. In another embodiment, the first coil unit 230-1 and the second coil unit 230-2 may have different lengths, widths, or heights. For example, in each of the structures 130, 230, and 11, the width may be shorter than the length. Additionally, the width of each component (130, 230, and 11) may alternatively be referred to as the "thickness" of each of the components 130-1 to 130-3 and 135. Further, for example, the heights H1, H2, and H3 of each of the structures 130, 230, and 11 may be the lengths of each structure in the optical axis direction.

[0224] The heights of the first coil unit 230-1 to the third coil unit 230-3 may be equal. In another embodiment, at least one of the heights of the first coil unit 230-1 to the third coil unit 230-3 may be different from the heights of the remaining coil units among them. For example, the height T11 of the first coil unit 230-1 may be equal to the height of the second coil unit 230-2, and the height T12 of the third coil unit 230-3 may be greater than the height T11 of the first coil unit 230-1 (T12 > T11). In another embodiment, the height T12 of the third coil unit 230-3 may be less than the height T11 of the first coil unit 230-1.

[0225] For example, the lengths L1, L2 in the length direction of each of the magnet units 130-1, 130-2, and 130-3 may be less than the lengths M1, M2 in the length direction of the respective coil units 230-1, 230-2, and 230-3 corresponding to the respective magnet units (L1 < M1, L2 < M2). In another embodiment, L1 and M1 may be equal to each other, and L2 and M2 may be equal to each other.

[0226] For example, the lengths W1 and W2 in the width direction of each of the magnet units 130-1, 130-2, and 130-3 may be less than the lengths in the width direction of each of the coil units 230-1, 230-2, and 230-3 corresponding to each magnet unit (W1 < K1, W2 < K2). In another embodiment, W1 and K2 may be equal to each other, and W2 and K2 may be equal to each other.

[0227] For example, the length M2 in the length direction of the third coil unit 230-3 may be greater than the length M1 in the length direction of the first coil unit 230-1 and / or the length in the length direction of the second coil unit 230-2 (M2 > M1). Additionally, for example, the length L2 in the length direction of the third magnet unit 130-3 may be greater than the length L1 in the length direction of the first magnet unit 130-1 and / or the length in the length direction of the second magnet unit 130-2 (L2 > L1).

[0228] Since M2 > M1 and L2 > L1, the first electromagnetic force generated by the third coil unit 230-3 and the third magnet unit 130-3 may be greater than the second electromagnetic force generated by the first coil unit 230-1 and the first magnet unit 130-1 and the third electromagnetic force generated by the second coil unit 230-2 and the second magnet unit 130-2. Therefore, in an embodiment, 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 can be reduced, and the reliability of the OIS operation can be improved.

[0229] In another embodiment, M2 and M1 may be equal to each other. Additionally, in another embodiment, L2 and L1 may be equal to each other.

[0230] Furthermore, for example, the length K2 in the width direction of the third coil unit 230-3 may be greater than the length K1 in the width direction of the first coil unit 230-1 and / or the length in the width direction of the second coil unit 230-2 (K2 > K1). In another embodiment, K2 and K1 may be equal to each other.

[0231] For example, the length W2 in the width direction of the third magnet unit 130-3 may be greater than the length W1 in the width direction of the first magnet unit 130-1 and / or the length in the width direction of the second magnet unit 130-2 (W2 > W1). Since W2 > W1, in an embodiment, 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 can be reduced, and the reliability of the OIS operation can be improved. In another embodiment, W1 and W2 may be equal to each other.

[0232] For example, the third magnet unit 130-3 may include a portion whose width decreases from the lower surface to the upper surface of the third magnet unit 130-3.

[0233] For example, the height H2 of the third magnet unit 130-3 may be less than the height H1 of the first magnet unit 130-1 and / or the height of the second magnet unit 130-2 (H2 < H1). For example, the length of the first magnet unit 130-1 in the optical axis direction may be equal to the length of the second magnet unit 130-2 in the optical axis direction. Since H2 < H1, in an embodiment, the weight of the lens driving device can be reduced and the power consumption of the AF driving and / or OIS driving can be reduced. In another embodiment, H2 and H1 may be equal to each other.

[0234] For example, the lengths L32 and L33 in the length direction of the dummy member 11 may be less than the length L2 in the length direction of the third magnet unit 130-3. For example, the length W31 in the width direction of the dummy member 11 may be less than the length W2 in the width direction of the third magnet unit 130-3 (W31 < W2).

[0235] For example, the length L32 of the first dummy member 11 and the length L33 of the second dummy portion 11B may be equal to each other, but not limited thereto. In other embodiments, the two may be different from each other. Additionally, the length in the width direction of the first dummy portion 11A and the length in the width direction of the second dummy portion 11B may be equal to each other, but not limited thereto. In other embodiments, the two may be different from each other.

[0236] Since W31 < W2, in an embodiment, sufficient space (e.g., the groove 14B of the housing 140) can be ensured to avoid spatial interference with the protruding portion 116 of the bobbin 110, and spatial interference between the protruding portion 116 (or the sensing magnet 180) and the dummy member 11 can be prevented. In another embodiment, W31 and W2 may be equal to each other.

[0237] In addition, the first separation distance in the optical axis direction between the first magnet unit 130-1 and the first coil unit 230-1, the second separation distance in the optical axis direction between the second magnet unit 130-2 and the second coil unit 230-2, and the third separation distance in the optical axis direction between the third magnet unit 130-3 and the third coil unit 230-3 may be equal to each other.

[0238] In other embodiments, the third separation distance may be smaller than the first separation distance and / or the second separation distance. And because the third separation distance is smaller than the first separation distance and / or the second separation distance, compared with the case where the first separation distance to the third separation distance are equal to each other, in another embodiment, the difference between the electromagnetic force generated in the X-axis direction and the electromagnetic force generated in the Y-axis direction may be further reduced.

[0239] For example, the height H3 of the dummy member 11 may be less than or equal to the height H2 of the third magnet unit 130 - 3 . In another embodiment, the height H3 of the dummy member 11 may be less than the height H2 of the third magnet unit 130 - 3 .

[0240] For example, the number of turns of the first coil unit 230-1 of the second coil 230 may be equal to the number of turns of the second coil unit 230-1. In another embodiment, the number of turns of the first coil unit 230-1 may be different from the number of turns of the second coil unit 230-2.

[0241] In addition, for example, the number of turns of the first coil unit 230-1 may be smaller than the number of turns of the second coil unit 230-2. The number of turns of the second coil unit 230-2 may be smaller than the number of turns of the third coil unit 230-2.

[0242] For example, the sum of the number of turns of the first coil unit 230-1 and the number of turns of the second coil unit 230-2 may be greater than the number of turns of the third coil unit 230-3. Here, the number of turns may be the total number of turns of the coil that rotates or winds in a circular shape. In another embodiment, the sum of the number of turns of the first coil unit 230-1 and the number of turns of the second coil unit 230-2 may be equal to or less than the number of turns of the third coil unit 230-3.

[0243] For example, the width of the single strand of the first coil unit 230 - 1 may be equal to the width of the single strand of the second coil unit 230 - 2 .

[0244] For example, the width of the single strand of the third coil unit 230-3 may be less than the width of the single strand of the first coil unit 230-1 (or the second coil unit 2320-2). In another embodiment, the width of the single strand of the third coil unit 230-3 may be equal to the width of the single strand of the first coil unit 230-1 (or the second coil unit 2320-2). In another embodiment, the width of the single strand of the third coil unit 230-3 may be greater than the width of the single strand of the first coil unit 230-1 (or the second coil unit 2320-2).

[0245] Embodiments may include three magnet units 130 - 1 to 130 - 3 and three OIS coils corresponding to the three magnet units 130 - 1 to 130 - 3 to reduce magnetic field interference between magnet units in adjacent lens driving devices in more than two camera devices.

[0246] Among the three magnet units 130-1 to 130-3, two magnet units 130-1 and 130-2 are configured to perform an AF operation for moving the bobbin 110 by interacting with the first coil unit 120-1 and the second coil unit 130-2 of the first coil 120, and perform an OIS operation for moving the housing 140 in one direction of the X-axis direction and the Y-axis direction by interacting with the first coil unit 230-1 and the second coil unit 230-2 of the second coil 230. In addition, among the three magnet units 130-1 to 130-3, the remaining magnet unit 130-3 is configured to perform an OIS operation for moving the housing 140 in the other direction of the X-axis direction and the Y-axis direction.

[0247] Since each of the first and second magnet units 130-1 and 130-2 is composed of a quadrupole magnet, in an embodiment, the electromagnetic force with a corresponding one of the first and second coil units 230-1 and 230-2 may be increased, and thus current consumption required for OIS driving may be reduced.

[0248] In addition, in the embodiment, by disposing the dummy member 11 at the opposite side of the third magnet unit 130 - 3 , oscillation due to weight eccentricity during the OIS operation may be prevented.

[0249] Generally, a first electromagnetic force generated by the interaction between a single magnet unit and a single OIS coil unit is smaller than a second electromagnetic force generated by the interaction between two magnet units and two OIS coil units, and the difference between the first and second electromagnetic forces may cause a malfunction of OIS driving.

[0250] The number of turns of the third coil unit 230-3 (hereinafter referred to as the "first number of turns") can be greater than the number of turns of the first coil unit 230-1 (hereinafter referred to as the "second number of turns") or / and the number of turns of the second coil unit 230-2 (hereinafter referred to as the "third number of turns"), thereby reducing the difference between the electromagnetic force generated in the X-axis direction and the electromagnetic force generated in the Y-axis direction.

[0251] In addition, the length L2 of the third magnet unit 130-3 may be greater than the length L1 of the first magnet unit 130-1 and / or the length of the second magnet unit 130-2, and the length M2 of the three coil units 230-3 may be greater than the length M1 of the first coil unit 230-1 and / or the length of the second coil unit 230-2. Thus, in an embodiment, the difference between the electromagnetic force generated in the X-axis direction and the electromagnetic force generated in the Y-axis direction may be reduced.

[0252] In another embodiment, the third magnet unit 130-3 and the dummy member 11 may be omitted. Another embodiment may replace the first coil 120 with a ring-shaped first coil surrounding the outer surface of the bobbin 110 about the optical axis.

[0253] In another embodiment, the third magnet unit 130-3 and the dummy component 11 can be omitted, and the third magnet unit 130-3 and the dummy component 11 can be replaced by a third magnet unit and a fourth magnet unit. At this time, each of the third magnet unit and the fourth magnet unit can have a structure that is the same as or similar to the first magnet unit 130-1. In another embodiment, a magnet unit corresponding to or facing the first coil can be provided on at least one of the corners of the housing 140 (e.g., each corner).

[0254] In another embodiment, the driving magnet for AF operation may include four magnet units disposed on the side or corner of the housing 140 instead of the three magnet units 130-1 to 130-3 and the dummy member 11. In another embodiment, the AF driving magnet may include two magnet units disposed on both sides or both corners of the housing 140. In another embodiment, the coil 120 may be disposed on the housing 140, and the magnet 130 may be disposed on the bobbin 110.

[0255] Next, the first position sensor 170 , the first circuit board 190 , and the capacitor 175 will be described.

[0256] Reference Figure 2 and Figure 4a , the first circuit board 190 may be disposed on the housing 140, or coupled to the housing 140. For example, the first circuit board 190 may be disposed on a side portion 141-3 of the housing 140. In another embodiment, the first circuit board 190 may be disposed on a corner portion of the housing 140. For example, the first circuit board 190 may be disposed in a groove 14A of the housing 140. For example, the first circuit board 190 may be disposed between two corner portions 142-2 and 142-3 of the housing 140. The first circuit board 190 may include terminals 3A to 3F conductively connected to the first position sensor 179.

[0257] For example, the terminals 3A to 3F may be disposed on at least one of the first surface and the second surface of the first circuit board 190. For example, the first surface of the circuit board 190 may be a surface of the first circuit board 190 facing the bobbin 110. And the second surface of the first circuit board 190 may be an opposite surface of the first surface of the first circuit board 190. For example, the first terminal 3A to the fourth terminal 3D may be disposed on the second surface of the first circuit board 190, and the fifth terminal 3E and the sixth terminal 3F may be disposed on the first surface of the first circuit board 190. For example, the first circuit board 190 may be a printed circuit board or an FPCB.

[0258] The first position sensor 170 may be disposed on the housing 140. For example, the first position sensor 170 may be disposed on one side portion (e.g., 141-3) of the housing 140, or may be coupled to one side portion of the housing 140. For example, in another embodiment, the first position sensor 170 may be disposed on one corner portion of the housing 140.

[0259] In another embodiment, the positions of the sensing magnet 180 and the first position sensor 170 may be arranged relative to each other. For example, the sensing magnet may be provided on the housing, and the first position sensor 170 may be provided on the bobbin 110. In this case, the first circuit board may be provided on the bobbin 110 together with the first position sensor, and a conductive pattern conductively connecting the first position sensor and the upper elastic member 150 may be directly formed on the bobbin 110 instead of the first circuit board.

[0260] For example, the first position sensor 170 may be disposed or mounted on the first circuit board 190. For example, the first position sensor 170 may be disposed or mounted on a first surface of the first circuit board 190.

[0261] The first position sensor 170 may detect the sensing magnet 180 provided on the bobbin 110 according to the movement of the bobbin 110. For example, the first position sensor 170 may detect the intensity of the magnetic field of the sensing magnet 180 and output an output signal according to the result of the detection.

[0262] For example, the first position sensor 170 may include a Hall sensor and a driver. For example, the Hall sensor of the first position sensor 170 may output an output signal (e.g., an output voltage) according to the result of detecting the strength of the magnetic force of the sensing magnet 180. For example, the magnitude of the output signal of the first position sensor 170 may be proportional to the strength of the detected magnetic force of the sensing magnet 180. For example, the driver of the first position sensor 170 may output a drive signal for driving the Hall sensor and a drive signal for driving the first coil 120.

[0263] In addition, for example, the driver of the first position sensor 170 can receive a clock signal, a data signal, and a power signal from the controller 830 or 780 using data communication using a protocol (e.g., I2C communication). For example, the power signal may include a first power signal and a second power signal. For example, the first power signal may be a ground voltage or 0. The second power signal may be a preset voltage for driving the driver, and may be a DC voltage or / and an AC voltage.

[0264] The first position sensor 170 includes a first terminal for a clock signal, a second terminal for a data signal, third and fourth terminals for a power signal, and fifth and sixth terminals for providing a driving signal to the first coil 120 .

[0265] The first position sensor 170 may be conductively connected to the first circuit board 190. For example, each of the first to fourth terminals of the first position sensor 170 may be conductively connected to a corresponding one of the first to fourth terminals 3A to 3D of the first circuit board 190.

[0266] The first coil 120 may be conductively connected to the first circuit board 190 and the first position sensor 170. For example, each of the fifth terminal and the sixth terminal of the first position sensor 170 may be conductively connected to a corresponding one of the fifth terminal 3E and the sixth terminal 3F of the first circuit board 190. For example, the fifth terminal 3E of the first circuit board 190 may be bonded to the fifth upper elastic member 150-5 by solder or a conductive adhesive member, and may be conductively connected to the fifth upper elastic member 150-5. The sixth terminal 3F of the first circuit board 190 may be bonded to the sixth upper elastic member 150-6 by solder or a conductive adhesive member, and may be conductively connected to the sixth upper elastic member 150-6.

[0267] The first circuit board 190 can provide a power signal to the first position sensor 170 through the first terminal 3A to the fourth terminal 3D, and can send and receive clock signals and data signals. In addition, the first circuit board 190 can provide a driving signal to the first coil 120 through the fifth terminal 3E and the sixth terminal 3F.

[0268] The lens driving device 100 may include a capacitor 175 conductively connected to the first position sensor 170. For example, the capacitor 175 may be disposed or mounted on the first circuit board 190.

[0269] Capacitor 175 may be in the form of a chip, in which case the chip may include a first terminal as one end of capacitor 175 and a second terminal as the other end of capacitor 175. Capacitor 175 may also be alternatively denoted as a "capacitive element" or a capacitor.

[0270] In another embodiment, the capacitor may be integrally formed with the first circuit board 190 such that it is included in the first circuit board 190. For example, the first circuit board 190 may include a capacitor having a first conductive layer, a second conductive layer, and an insulating layer (e.g., a dielectric layer) disposed between the first conductive layer and the second conductive layer.

[0271] For example, the capacitor 175 may be connected in parallel with the two terminals of the first position sensor 170 to which power is supplied. Alternatively, for example, the capacitor 175 is connected in parallel with the third terminal and the fourth terminal (e.g., 3C, 3D) of the first circuit board 190, and the third terminal and the fourth terminal are conductively connected to the two terminals of the first position sensor 170 to which power is supplied.

[0272] For example, one end of capacitor 175 (or the first terminal of the capacitor chip) can be conductively connected to the third terminal 3C of the circuit board 190, and the other end of capacitor 175 (or the second terminal of the capacitor chip) can be conductively connected to the fourth terminal 3D of the circuit board 190.

[0273] The capacitor 175 is conductively connected in parallel with the third terminal 3C and the fourth terminal 3D of the first circuit board 190. The capacitor 175 can be used as a smoothing circuit to remove ripples included in the power signal supplied from the outside to the first position sensor 170. Therefore, a stable and uniform power signal can be provided to the first position sensor 170.

[0274] The capacitor 175 is electrically connected in parallel with the third terminal 3C and the fourth terminal 3D of the circuit board 190. Thus, the first position sensor 170 can be protected from noise of high frequency components or ESD (electrostatic discharge) from the outside.

[0275] Reference Figure 6a and Figure 6b , the lens driving device 100 may include an elastic member combined with at least one of the bobbin 110 and the housing 140. The elastic member may elastically support the bobbin 110 relative to the fixing unit (e.g., the housing 140). For example, the elastic member may include at least one of an upper elastic member 150 and a lower elastic member 160.

[0276] For example, the upper elastic member 150 may be combined with the bobbin 110 and the housing 140. For example, the upper elastic member 150 may be combined with the upper portion, upper surface, or upper end of the bobbin 110 and the upper portion, upper surface, or upper end of the housing 140. For example, the lower elastic member 160 may be combined with the bobbin 110 and the housing 140. For example, the lower elastic member 160 may be combined with the lower portion, lower surface, or lower end of the bobbin 110 and the lower portion, lower surface, or lower end of the housing 140.

[0277] The upper elastic member 150 may include a plurality of upper elastic members. For example, the upper elastic member 150 may include a plurality of upper elastic members 150-1 to 150-7 that are conductively separated from each other. For example, the plurality of upper elastic members 150-1 to 150-7 may be disposed to be spaced apart from each other.

[0278] Figure 6a Seven conductively separated upper elastic members are shown, but the number is not limited thereto, and in another embodiment, the upper elastic member may include one or more than two upper elastic members.

[0279] At least one of the first to seventh upper elastic members 150-1 to 150-7 may include a first inner frame 151 coupled to the bobbin 110. At least one of the first to seventh upper elastic members 150-1 to 150-7 may include a first outer frame 152 coupled to the housing 140. At least one of the first to seventh upper elastic members 150-1 to 150-7 may include a first frame connection portion 153 connecting the first inner frame 151 and the first outer frame 152. The elastic member may alternatively be expressed as a "spring" or an "elastic unit", the inner frame may be expressed as an "inner", the outer frame may be expressed as an "outer", and the frame connection portion may be expressed as a "connection portion".

[0280] For example, the first inner frame 151 of the upper elastic member 150 may include a hole 151a for coupling with the first coupling portion 113 of the bobbin 110. For example, the first outer frame 152 of the upper elastic member 150 may include a hole 152a for coupling with the first coupling portion 143 of the housing 140.

[0281] For example, at least one of the holes 151a and 152a of the first inner frame 151 and the first outer frame 152 may include at least one slit through which the adhesive member enters into the space between the first coupling parts 113 and 143 and the holes 151a and 152a.

[0282] For example, the first outer frame 152 includes a first coupling portion 91 coupled to the housing 140 , a second coupling portion 92 coupled to the support member 220 , and a connection portion 93 connecting the first coupling portion 91 and the second coupling portion 92 .

[0283] The first coupling portion 91 may include at least one coupling region (eg, corner portions 142-1 to 142-4) coupled with the housing 140. For example, the coupling region of the first coupling portion 91 may include at least one hole 152a coupled with the first coupling portion 143 of the housing 140.

[0284] For example, the coupling area may have more than one hole, and more than one first coupling portion may be provided in the corner portions 142-1 to 142-4 of the housing 140 corresponding to the coupling area. Figure 6a In the embodiment of FIG. 1 , the combining area of ​​the first combining portion 91 is implemented to include a hole 152 a , but in other embodiments, the combining area has various shapes sufficient to be combined with the housing 140 , for example, a groove shape, etc.

[0285] The second coupling portion 292 may be coupled to one end of the support member 220. For example, the second coupling portion 292 may have a hole 92A through which the support member 220 passes. One end of the support member 220 passing through the hole 92A may be directly coupled to the second coupling portion 92 through a conductive adhesive member or solder 902 (see Figure 7a ), and the second bonding portion 92 and the support member 220 may be conductively connected to each other. For example, the second bonding portion 92 is a region in which the solder 902 is disposed to bond with the support member 220, and may include the hole 92A and the region around the hole 92A.

[0286] In an embodiment where two supporting members are provided at one corner of the housing 140, the first outer frame 151 may include two second coupling portions 92-1 and 92-2. For example, the second coupling portion 92 may include a 2-1 coupling portion 92-1 coupled to one of the two supporting members and a 2-2 coupling portion 92-2 coupled to the other of the two supporting members.

[0287] The connecting portion 93 may connect the first combining portion 91 and the second combining portion 92. For example, the connecting portion 93 may connect the combining regions of the second combining portion 92 and the first combining portion 91.

[0288] For example, the connecting portion 93 is a first connecting portion connecting the first connecting portion 91 and the 2-1 connecting portion 92-1 and a second connecting portion connecting the first connecting portion 91 and the 2-2 connecting portion 92-2. The connecting portion 93 may include a bent portion bent at least once or a bent portion bent at least once. In another embodiment, the connecting portion may have a straight line shape.

[0289] For example, the first coupling portion 91 may contact the upper surface (eg, the first surface 60A) of the corner portions 142-1 to 142-4 of the housing 140 and may be supported by the corner portions 142-1 to 142-4. For example, the second coupling portion 92 may not be supported by the housing 140 and may be spaced apart from the housing 140.

[0290] The lens driving device 100 may include a damper 88 disposed in the hollow space between the connecting portion 93 and the housing 140 to prevent oscillation caused by vibration. For example, the damper 88 may contact, attach or combine with at least a portion of the housing 140 (e.g., the third surface 60C) and the connecting portion 93.

[0291] The upper elastic member 150 may include at least one first outer frame 152 coupled with at least one corner portion of the plurality of corner portions 142 - 1 to 142 - 4 of the case 140 .

[0292] For example, at least one of the plurality of upper elastic members may be disposed at the plurality of corner portions 142 - 1 to 142 - 4 of the housing 140 .

[0293] For example, the first to sixth upper elastic members 150 - 1 to 150 - 6 may include a first outer frame 152 disposed at corner portions 142 - 1 to 142 - 4 of the case 140 .

Each of the engaging portions 41 to 44 and the first coil 120 may be bonded to the first coil 120 by solder or a conductive adhesive 901 (see Figure 2 ) are combined with each other and are conductively connected.

[0302] For the first to fourth joining portions 41 to 44, the term "joining portion" may be replaced with a pad portion, a connection terminal, a solder portion, or an electrode portion. The first coil unit 120-1 and the second coil unit 120-2 may be connected in series through the fifth to seventh upper elastic members 150-5 to 150-7.

[0303] For example, each of the fifth to sixth upper elastic members 150 - 5 to 150 - 6 may be bonded and conductively connected to a corresponding one of the fifth to sixth terminals 3E to 3F of the first circuit board 190 by solder or a conductive adhesive.

[0315] For example, the bobbin 110 may include a protrusion 115 corresponding to the first frame connection portion 153 of the upper elastic member 150 and protruding from the upper surface of the bobbin 110. For example, a recess for accommodating the damper 85 may be formed on the protrusion 115. In addition, the first frame connection portion 153 may include a protrusion 53A protruding in a direction perpendicular to the optical axis. The protrusion 53A may protrude toward the protrusion 115 of the bobbin 110. For example, a hole 53B may be formed on the protrusion 54A to increase the contact area with the damper 85.

The support member 220 may conductively connect at least one of the upper elastic member 150 or the lower elastic member 160 to the second circuit board 250.

[0318] For example, the support member 220 may be combined with the upper elastic member 150 by solder or a conductive adhesive and may be conductively connected to the upper elastic member 150. The support member 220 may be conductively connected to the second circuit board 250.

[0321] The support member 220 may include a plurality of support members 220 - 1 to 220 - 6 .

[0322] For example, at least one supporting member may be provided at each corner portion 142-1 to 142-4 of the housing 140. For example, two supporting members may be provided at each corner portion 142-1 to 142-4 of the housing 1400. For example, the lens driving device 100 may include a total of eight lines.

In another embodiment, two support members may be provided at at least one of the corners of the housing 140, and one support member may be provided at at least another of the corners of the housing 140.

[0324] In another embodiment, for example, two support members may be provided at each of the two corners of the housing 140, and one support member may be provided at each of the two corners of the housing 140. For example, two support members may be provided at each of the two corners of the housing facing each other in the first diagonal direction, and one support member may be provided at each of the two corners of the housing facing each other in the second diagonal direction. The first diagonal direction and the second diagonal direction may be directions intersecting each other. For example, the first diagonal direction and the second diagonal direction may be perpendicular to each other.

[0325] For example, each of the first to fourth supporting members 220 - 1 to 220 - 4 may be bonded and conductively connected to a corresponding one of the first to fourth upper elastic members 150 - 1 to 150 - 4 by solder or the conductive adhesive 902 .

[0326] For example, each of the fifth and sixth supporting members 220 - 5 and 220 - 6 may be bonded and conductively connected to a corresponding one of the fifth and sixth upper elastic members 150 - 5 and 150 - 6 by solder or the conductive adhesive 902 .

[0327] For example, the fifth upper elastic member 220-5 may include two wires 220-5A and 220-5B, and at least one of the two wires 220-5A and 220-5B may be conductively connected to the second circuit board 250. The sixth upper elastic member 220-6 may include two wires 220-6A and 220-6B, and at least one of the two wires 220-6A and 220-6B may be conductively connected to the circuit board 250.

[0328] For example, each of the first to fourth supporting members 220-1 to 220-4 may be conductively connected to a corresponding one of the first to fourth terminals 3A to 3D of the first circuit board through the first to fourth upper elastic members 150-1 to 150-4.

[0329] For example, each of the fifth and sixth supporting members 220-5 and 220-6 may be conductively connected to a corresponding one of the fifth and sixth terminals 3E and 3F of the first circuit board 190 through the fifth to seventh upper elastic members 150-5 to 150-7.

[0330] For example, the other end of the support member 220 may be soldered or conductively bonded to the conductive adhesive 903 (see Fig.19 ) is bonded to and conductively connected to the terminal member 27. For example, the other end of the support member 220 may be located inside the solder 903 and may not be exposed to the outside of the solder (see Fig.21 In another embodiment, for example, the other end of the support member 220 may protrude to the outside of the solder 903 and be exposed to the outside of the solder 903 .

[0331] For example, the terminal member 27 may be conductively connected to the second circuit board 250 , and the support member 220 may be conductively connected to the second circuit board 250 through the terminal member 27 .

[0332] Each of the support members 220-1 to 220-6 may be conductively connected to a corresponding one of the terminal members 27A to 27F. For example, the support members 220-1 to 220-6 may conductively connect the upper elastic members 150-1 to 150-6 and the terminal portions 27A to 27F.

[0333] The support members 220-1 to 220-6 may be spaced apart from the housing 140 and not fixed to the housing 140, but one ends of the support members 220-1 to 220 may be directly coupled or connected to the second coupling portions 92 of the upper elastic members 150-1 to 150-6, respectively, by solder or a conductive adhesive 902.

[0334] For example, the first position sensor 170 may be conductively connected to the second circuit board 250 through the upper elastic member 150 , the support member 220 , and the terminal member 27 .

[0335] In another embodiment, the terminal member 27 may be omitted, and the other end of the support member 220 may be directly connected or bonded to the second circuit board 250 using solder or a conductive adhesive. For example, the other end of the support member 220 may be directly connected or bonded to the lower surface of the second circuit board 250. In another embodiment, the other end of the support member 220 may be bonded to the base 210, and a wiring or circuit pattern may be formed on the base 210 to conductively connect the other end of the support member 220 with the second circuit board 250.

[0336] In another embodiment, the support member 220 may be integrally formed with the upper elastic member 150 .

[0337] Reference Figures 8 to 9c , the second circuit board 250 is disposed below the housing 140 and / or the bobbin 110. Alternatively, for example, the second circuit board 250 may be disposed below the lower elastic member 160. Alternatively, for example, the second circuit board 250 may be disposed below the housing 140. For example, the second circuit board 250 may be disposed on the base 210.

[0338] For example, the second circuit board 250 may include a body 252 disposed on the upper surface of the base 210 and an opening 24A or a hollow portion formed on the body 252 .

[0339] The opening 24A of the second circuit board 250 corresponds to at least one of the opening 25A of the bobbin 110 , the opening 140A of the housing 140 , and / or the opening 28A of the base 210 .

[0340] For example, when viewed from the top side, the shape of the body 252 of the second circuit board 250 may match or correspond to the upper surface of the base 210 , for example, may be a square.

[0341] The second circuit board 250 may include a terminal portion 253 extending from the body 252. The terminal portion 253 may be bent from the body 252 and extend to the side (or outer side) of the base 210. The body 252 may be referred to as an "upper portion" or a first portion, and the terminal portion 253 may be referred to as an "extension portion" or a second portion.

[0342] The terminal part 253 of the second circuit board 250 may include a plurality of terminals 251 which receive an electrical signal from the outside or output an electrical signal to the outside.

[0343] For example, the second circuit board 250 may include two terminal portions disposed on both sides of the body 252 facing each other. However, in another embodiment, the second circuit board 250 may include more than one terminal portion disposed at at least one or more sides of the body 252.

[0344] A driving signal may be provided to each of the first position sensor 170, the second position sensor 240, and the second coil 230 through a plurality of terminals 251 provided on a terminal portion 253 of the second circuit board 250. The terminal portion 253 of the second circuit board 250 may receive an output signal of each of the first position sensor 170 and the second position sensor 240. Alternatively, in another embodiment, a driving signal may be supplied to the first coil 120 through the terminal 251.

[0345] For example, each of the first position sensor 170 and the second position sensor 240 may be conductively connected to a corresponding one of the terminals 251 of the second circuit board 250 .

[0346] The second circuit board 250 may be implemented as a PCB or an FPCB. In another embodiment, the terminal may be directly formed on the surface of the base 210 instead of the second circuit board 250 using a surface electrode method or the like.

[0347] The second circuit board 250 may include an escape portion 23A through which the support member 220 passes, so as to avoid spatial interference with the support member 220. Figure 8 In the embodiment, the avoidance portion 23A may be formed at the corner of the body 252, and the avoidance portion 23A may have a cutout shape or a groove shape. In another embodiment, the avoidance portion of the second circuit board 250 may be in the form of a hole or a through hole, and the support member may pass through the hole or through hole of the second circuit board. In another embodiment, the second circuit board 250 may not have the avoidance portion, and the support members 220-1 to 220-4 may be conductively connected to the circuit pattern or pad formed on the upper surface of the second circuit board 250 by solder or the like.

[0348] The second circuit board 250 may be bonded and conductively connected to the second coil 230 using solder or a conductive adhesive, and may include at least one pad E1 to E6 or at least one terminal.

[0349] For example, the second circuit board 250 includes two pads E1 and E2 conductively connected to the first coil unit 230-1 of the second coil 230, two pads E3 and E4 conductively connected to the second coil unit 230-2, and two pads E5 and E6 conductively connected to the third coil unit 230-3. For example, six pads E1 to E6 conductively connected to the second coil 230 may be provided on the lower surface of the second circuit board 250. In an embodiment in which the second coil 230 is provided on the upper surface of the second circuit board 250, pads conductively connected to the second coil 230 may be provided on the upper surface of the second circuit board 250.

[0350] The second circuit board 250 may include pads Q1 to Q6 or terminals conductively connected to the terminal member 27 by solder or a conductive adhesive.

[0351] For example, the second circuit board 250 may include a plurality of pads Q1 to Q6 , and each of the plurality of pads Q1 to Q6 may be coupled to and conductively connected to a corresponding one of the plurality of terminal portions 27A to 27E.

[0352] The pads Q1 to Q6 may be provided on at least one of the lower surface of the second circuit board 250 or the upper surface of the second circuit board 250. For example, the pads Q1 to Q6 may include at least one of a first portion provided on the lower surface of the second circuit board 250 and a second portion provided on the upper surface of the second circuit board 250. In addition, the pads Q1 to Q6 may further include a third portion connecting the first portion and the second portion. For example, the third portion of the pads Q1 to Q6 may be provided on the outer side of the second circuit board 250.

[0353] For example, the pads Q1 to Q6 may be arranged to contact the edge of the second circuit board 250 or the side of the second circuit board 250. For example, the pads Q1 to Q6 may be arranged at the corner portion of the second circuit board 250. For example, the pads Q1 to Q6 may be formed on the edge of the second circuit board 250 adjacent to the avoidance portion 23A of the second circuit board 250. In addition, each of the pads Q1 to Q6 may be placed in contact with a corresponding one of the terminal members 27A to 27F. At least a portion of each of the pads Q1 to Q6 may overlap with a corresponding one of the terminal members 27A to 27F in the optical axis direction or the first direction.

[0354] Reference Figure 8 and Figures 14 to 17 , the base 210 may be disposed below the second circuit board 250. In addition, the base 210 may be disposed below the housing 140 and / or the bobbin 110.

[0355] The base 210 may have an opening 28A corresponding to the opening 25A of the bobbin 110 or / and the opening 140A of the housing 140. The base 210 may have a shape matching or corresponding to the cover member 300, for example, the base 210 may have a square shape.

[0356] A support portion 255 or a holding portion may be provided in an area of ​​the base 210 facing the terminal 251 of the second circuit board 250. The support portion 255 of the base 210 may support the terminal portion 253 of the second circuit board 250 on which the terminal 251 is formed. For example, the support portion 255 may be in the form of a groove recessed from the outer surface of the base 210.

[0357] The base 210 may be formed with an escape portion 212 at a corner or corner region thereof to avoid spatial interference with the support member 220. For example, the escape portion 212 may be in the form of a hole or a through hole. Fig.14 In one embodiment, the escape portion 212 may be a through hole formed in the step portion 30 of the base 210, but in another embodiment, the escape portion may be formed by cutting or removing a corner or corner area of ​​the base 210 where the step portion 30 is omitted. In another embodiment, the escape portion may be in the form of a recess or groove.

[0358] The base 210 may include a first surface 210A that contacts or supports the body 252 of the second circuit board 250. For example, a lower surface of the second circuit board 250 (or the body 252) may contact the first surface 210A of the base 210.

[0359] The base 210 may include a second surface 210B having a step difference with the first surface 210A in the optical axis direction. For example, the second surface 210B may be located below the first surface 210A. For example, the second surface 210B may be closer to the lower surface of the base 210 than the first surface 210A. For example, the second surface 210B may be located between the opening 28A of the base 210 and the outer side surface of the base 210.

[0360] The second coil 230 may be disposed on the base 210. For example, the second coil 230 may be disposed on the upper surface of the base 210. For example, the second coil 230 may be disposed between the base 210 and the second circuit board 250. For example, the second coil 230 may be disposed on the second surface 210B of the base 210. For example, the second coil 230 may be in contact with the second surface 210B of the base 210.

[0361] The base 210 may include a first region in which the second coil 230 is disposed and a second region in which the second coil 230 is not disposed.

[0362] For example, the first area of ​​the base 210 may alternatively be expressed as a "receiving portion" or a "receiving area". For example, the first area of ​​the base 210 may be expressed as a "settling portion". The first area of ​​the base 210 may be grooves 213A to 213C or recesses. For example, the grooves 213A to 213C of the base 210 are recessed from the first surface 210A of the base 210. For example, the bottom surface of the grooves 213A to 213C of the base 210 may be the second surface 210B of the base 210. The outer surface of the base 210 may include an open area.

[0363] For example, the first region of the base 210 may include a bottom surface (eg, 210B) located lower than the uppermost surface of the base 210. In addition, the first region of the base 210 may include a protrusion 215, a protruding region, or a protrusion disposed on the bottom surface 210B.

[0364] At least a portion of the second coil 210 may be disposed in the first region of the base 210. The second circuit board 250 may be disposed on the first region of the base 210, and the lower surface of the second circuit board 250 may be spaced apart from the bottom surface 210B of the first region of the base 210. The first region of the base 210 may include a protrusion 215, a protruding region, or a protrusion that protrudes higher than the bottom surface 210B. For example, the protrusion 215 may protrude from the second surface 210B of the base 210.

[0365] For example, the protrusion 215, the protruding area or the protrusion of the first area of ​​the base 210 can be arranged in the hollow part (or the center hole) of the coil units 230-1 to 230-3 of the second coil 230. For example, the base 210 may include three grooves 213A to 213C to accommodate the three coil units 230-1 to 230-3. For example, the depth of each groove 213A, 213B and 213C may be greater than the length in the optical axis direction of the coil units 230-1 to 230-3 of the second coil 230. This prevents the second circuit board 250 combined with the coil unit from rising or separating from the first surface 210A of the base 210, and this also prevents the weakening of the bonding force between the second circuit board 250 and the base 210.

[0366] In another embodiment, the depth of the grooves 213A, 213B, and 213C may be equal to the length in the optical axis direction of the coil units 230-1 to 230-3 of the second coil 230. In another embodiment, the depth of the grooves 213A, 213B, and 213C may be less than the length in the optical axis direction of the coil units 230-1 to 230-3 of the second coil 230. For example, the depth of the grooves 213A, 213B, and 213C may be the distance from the first surface 30A of the base 210 to the bottom surface 210B of the grooves 213A to 213C.

[0367] The base 210 may include a third surface 30A below the first surface 210A. The third surface 30A may be provided at a corner of the base 210. For example, the third surface 30A may be the upper surface of the step portion 30 of the base 210. For example, the third surface 30A may be provided adjacent to the escape portion 212 of the base 210. For example, the third surface 30A may be located at a position higher than the lower surface of the base 210. For example, the third surface 30A may be located at a position lower than the second surface 210B. In another embodiment, the third surface 30A may be higher than the second surface 210B or may have the same height.

[0368] For example, the first surface 210A, the second surface 210B and the third surface 30A may be parallel to each other. In addition, for example, the first surface 210A, the second surface 210B and the third surface 30A may be perpendicular to the optical axis. In another embodiment, at least one of the first to third surfaces may not be parallel to the other surfaces.

[0369] The base 210 may further include a groove 213D formed on the first surface 210A and recessed from the first surface 210A. The groove 213D may be formed in other regions of the first surface 210A of the base 210 except for the regions where the other grooves 213A to 213C are formed.

[0370] For example, the base 210 may be an injection molded material. By forming the groove 213D in other regions of the base 210, it is possible to prevent the thickness of other regions of the base 210 from being formed abnormally thick.

[0371] The base 210 may include a step 211, and when the cover member 300 is fixed to the base by an adhesive, an adhesive may be applied to the step 211. At this time, the step 211 may be formed on the outer surface of the base 210. The step 211 is configured to guide the side plate 302 of the cover member 300. The step 211 faces the lower end of the side plate 302 of the cover member 300. For example, the step 211 and the side plate 302 of the cover member 300 may be bonded to each other using an adhesive. In addition, a placement portion (not shown) on which the filter 610 of the camera device 200 is mounted may be formed on the lower surface of the base 210.

[0372] A guide protrusion 217 may be formed at an edge of the upper surface of the base 210 and protrudes from the upper surface (e.g., the first surface 210A) of the base 210. The guide protrusion 217 is used to guide the body 252 of the second circuit board 250 and support the side of the body 252 to prevent the body 252 from falling off the base 210.

[0373] For example, the second coil 230 may be disposed between a lower surface of the second circuit board 250 and an upper surface (eg, the first surface 210A) of the base 210 .

[0374] The second coil 230 may include a plurality of coil units. For example, the second coil 230 may include first to third coil units 230-1 to 230-3.

[0375] For example, the first coil unit 230-1 may face or overlap the first magnet unit 130-1 in the optical axis direction, the second coil unit 230-2 may face or overlap the second magnet unit 130-2 in the optical axis direction, and the third coil unit 230-3 may face or overlap the third magnet unit 130-3 in the optical axis direction.

[0376] For example, three magnets 130-1 to 130-3 can be set on three of the four sides of the shell 140, and the first coil unit 230-1 to the third coil unit 230-3 can be set on three sides or three sides of the base 210 corresponding to or facing the magnets 130-1 to 130-3 in the optical axis direction.

[0377] In another embodiment, three magnets may be disposed on three of the four corners of the housing 140, and the first to third coil units may be disposed on the three corners of the base 210 corresponding to or facing the magnets 130-1 to 130-3 in the optical axis direction.

[0378] Each of the first to third coil units 230 - 1 to 230 - 5 may be hollow or a closed curve having a central hole, for example, a ring shape, and the central hole may be formed to face the optical axis direction.

[0379] For example, each of the first coil unit 230-1 to the third coil unit 230-3 can be in the form of a winding coil, a coil bundle, a coil body or a coil block, rather than a fine pattern (FP) coil. Due to problems such as resistance during manufacturing, the FP coil cannot ensure a sufficient number of coil turns, and the number of coil turns is limited. Therefore, the electromagnetic force caused by the interaction with the magnet 130 can be reduced or weakened. In a structure in which two supporting members are provided at each corner of the housing 140 according to an embodiment, sufficient electromagnetic force is required to overcome the restoring force of the supporting member, but in the case of using the FP coil, such sufficient electromagnetic force cannot be ensured.

[0380] On the other hand, the winding coil has no limitation on the number of turns of the coil, and can have 1.5 times or more the number of turns of the FP coil. For example, under the condition of the same resistance, the winding coil can ensure 1.5 times or more the number of turns compared with the FP coil.

[0381] Thus, the embodiment can ensure a sufficient number of turns of the second coil 230 and, when OIS driving is performed, ensure a sufficient electromagnetic force to overcome the restoring force of the support member 220 .

[0382] In another embodiment, the second coil 230 may be implemented as a fine pattern (FP) coil.

[0383] The protrusion 215 of the base 210 may be coupled, inserted into, or disposed in the hollow portions (or center holes) of the coil units 230 - 1 to 230 - 3 of the second coil 230 .

[0384] For example, the height of the protrusion 215 may be lower than or equal to the height of the upper surface or upper end of the second coil 230 (or the coil units 230-1 to 230-3). The height of the protrusion 215 may be less than or equal to the length of the coil units 230-1 to 230-3 in the optical axis direction. The height of the protrusion 215 may be the protruding height of the protrusion 215.

[0385] For example, the upper surface of the protrusion 215 may be lower than or equal to the first surface 210A of the base 210. This is because if the height of the protrusion 215 is higher than the first surface 210A of the upper surface of the base 210, the lower surface of the second circuit board 250 and the first surface 210A of the base 210 may rise or separate.

[0386] For example, the first to third coil units 230 - 1 to 230 - 3 may be fixed or attached to the lower surface of the second circuit board 250 using solder or a conductive adhesive and may be conductively connected to the second circuit board.

[0387] The second position sensor 240 may be conductively connected to the second circuit board 250. The second position sensor 240 may be disposed or mounted on the second circuit board 250. The second position sensor 240 may be disposed on the base 210. The base 210 may include a placement portion 214 (214A, 214B) on which the second position sensor 240 is disposed or placed. For example, the placement portions 214A and 214B may be in the form of a groove or a hole. For example, the placement portions 214A and 214B may be disposed in the grooves 213A and 213C of the base 210. For example, the placement portions 214A and 214B may be formed in the protrusion 215 of the base 210.

[0388] For example, the second position sensor 240 may be disposed between the second circuit board and the base 210. For example, the second position sensor 240 may be fixed or attached to the lower surface of the second circuit board 250 using solder or a conductive adhesive and may be conductively connected to the second circuit board 250.

[0389] The second position sensor 240 may include a first sensor 240A and a second sensor 240B spaced apart from each other. For example, the first sensor 240A and the second sensor 240B may be disposed between the second circuit board 250 and the base 210. For example, the first sensor 240A and the second sensor 240B may be disposed between the lower surface of the second circuit board 250 and the upper surface 30 of the base 210.

[0390] The second position sensor 240 can detect the displacement or position of the housing 140 in a direction perpendicular to the optical axis. For example, when the housing 140 moves in a direction perpendicular to the optical axis, the second position sensor 240 can detect the magnetic field of the magnet 130 and output an output signal. The output signal of the second position sensor 240 can be used to detect the displacement (or position) of the housing 140 in a direction perpendicular to the optical axis.

[0391] Each of the first sensor 240A and the second sensor 240B may be a Hall sensor, and any sensor capable of detecting magnetic field strength may be used. For example, each of the first sensor 240A and the second sensor 240B may be implemented as a position detection sensor such as a Hall sensor or may be implemented as a driver IC including a Hall sensor.

[0392] For example, the first sensor 240A may be disposed in the central hole of the first coil unit 230-1, and the second sensor 240B may be disposed in the central hole of the third coil unit 230-3. In another embodiment, the first sensor 240A may be located outside the central hole of the first coil unit 230-1, and the second sensor 240B may be located outside the central hole of the third coil unit 230-3.

[0393] For example, the first sensor 240A may correspond to, face, or overlap the first magnet unit 130 - 1 in the optical axis direction, and the second sensor 240B may correspond to, face, or overlap the third magnet unit 130 - 3 in the optical axis direction.

[0394] For example, the first sensor 240A can detect the first magnet unit 130-1 (or the strength of the magnetic field of the first magnet unit) and output a first output signal. The second sensor 240B can detect the third magnet unit 130-3 (or the strength of the magnetic field of the third magnet unit) and output a second output signal. The first output signal and the second output signal can be used to detect the displacement (or position) of the OIS movable unit in a direction perpendicular to the optical axis. Here, the OIS movable unit may include an AF movable unit and a component mounted on the housing 140.

[0395] For example, the first sensor 240A and the second sensor 240B may not overlap with the second coil 230 (eg, the first to third coil units 230 - 1 to 230 - 4 ) in the optical axis direction.

[0396] For example, the first sensor 240A and the second sensor 240B may be conductively connected to the terminal 251 of the second circuit board 250. For example, a driving signal may be supplied to each of the first sensor 240A and the second sensor 240B through the terminal 251 of the second circuit board 250, and a first output signal of the first sensor 240A and a second output signal of the second sensor 240B may be output through the terminal 251 of the second circuit board 250.

[0397] The controller 830 of the camera apparatus 200 or the controller 780 of the portable terminal 200A may sense or detect the displacement of the OIS movable unit using the first output signal of the first sensor 240A and the second output signal of the second sensor 240B.

[0398] Through the interaction between the first to third magnet units 130-1 to 130-3 and the first to third coil units 230-1 to 230-3, the OIS movable unit (e.g., housing 140) can move in a direction perpendicular to the optical axis (e.g., in the x-axis and / or y-axis direction). Thus, hand shake correction can be performed.

[0399] The base 210 may include a side and a corner (or corner). For example, the base 210 may include four sides and four corners. The three grooves 213A to 213C may be formed on three of the four sides of the base 210, and the groove 213D may be formed on the remaining side. The corners of the base 210 may correspond to or face the corners 142-1 to 142-4 of the housing 140 in the optical axis direction.

[0400] The above-mentioned avoidance portion 212 may be formed at a corner portion of the base 210, and the third surface 30A may be formed at a corner portion of the base 210. For example, the base 210 may include a step portion 30, and the step portion 30 includes a first surface 210A and a third surface 30A having a step difference in the optical axis direction. For example, the step portion 30 may be a region of a corner portion of the base 210. For example, the avoidance portion 212 may be formed at the step portion 30 of the base 210. For example, the avoidance portion 212 may penetrate the step portion 30 in the optical axis direction. For example, the avoidance portion 212 may overlap with the support member 220 in the optical axis direction.

For example, the terminal member 27 may be disposed at a corner portion (or corner) of the base 210. In another embodiment, the terminal member may be disposed on a side portion of the base 210. For example, the terminal member 27 may be disposed at a step portion 30 of the base 210 or may be combined with the step portion 30.

For example, the terminal member 27 may include as many terminals as the number of the support members. The terminal member 27 may include a conductive material, for example, a conductive metal.

[0406] The terminal member 27 includes a first portion 50A coupled to the support member 220 by solder or a conductive adhesive, a second portion 51A coupled to the second circuit board 250 by solder or a conductive adhesive, and a third portion 51B connecting the first portion 50A and the second portion 51A. The first portion 50A may be expressed as a "first coupling portion", the second portion 51A may be expressed as a "second coupling portion", and the third portion 51B may be expressed as a "connecting portion". In addition, the first portion 50A may alternatively be expressed as a "main body", and the second portion 51A and the third portion 51B may alternatively be expressed as an "extension portion 50B".

[0407] One end of the extension 50B may be conductively connected to the second circuit board 250. For example, one end of the extension 50B may be combined and conductively connected to the pads Q1 to Q6 of the second circuit board 250 using solder or a conductive adhesive. For example, the extension 50B of each of the plurality of terminals 27A to 27F may be combined and conductively connected to a corresponding one of the pads Q1 to Q6 of the second circuit board 250 using solder or a conductive adhesive.

[0408] The first portion 50A of the terminal member 27 may include a bonding area for bonding with the support member 220.

[0412] The first portion 50A of the terminal member 27 may be disposed between the first surface 30A of the base 210 and the lower surface 210C of the base 210 (see Fig.19 (or bottom)). For example, the first portion 50A of the terminal member 27 may be disposed on the step portion 30 of the base 210. For example, the first portion 50A of the terminal member 27 may be disposed on or coupled to the lower surface 30B of the step portion 30 of the base 210. For example, the lower surface 30B of the step portion 30 may be disposed higher than the lower surface 210C of the base 210 and disposed lower than the first surface 210A of the base 210.

[0413] In another embodiment, the first portion 50A of the terminal member 27 may be disposed on or coupled to the upper surface (or third surface 30A) of the step portion 30 of the base 210. For example, the upper surface 30A of the terminal member 27 may be disposed higher than the lower surface of the base 210 and lower than the first surface 210A of the base 210.

[0414] For example, the lower surface of the first portion 50A of the terminal member 27 may be set to be lower than the lower surface of the coil unit (e.g., 230-2) of the second coil 230. For example, the upper surface of the first portion 50A of the terminal member 27 may be set to be lower than the lower surface of the coil units 230-1 to 230-3 of the second coil 230. In another embodiment, for example, the lower surface (or upper surface) of the first portion 50A of the terminal member 27 may be located on the same plane as the lower surface of the coil units 230-1 to 230-3 of the second coil 230. In another embodiment, for example, the lower surface (or upper surface) of the first portion 50A of the terminal member 27 may be set to be higher than the lower surface of the coil units 230-1 to 230-3 of the second coil 230.

[0415] The first portion 50A of the terminal member 27 may be disposed on or bonded to the step portion 30 of the base 210. For example, the first portion 50A of the terminal member 27 may be disposed on or bonded to the lower surface 30B of the step portion 30 of the base 210. At least a portion of the first portion 50A of the terminal member 27 may be exposed from the lower surface 30B of the step portion 30 of the base 210. The other end of the support member 220 may be bonded to at least a portion of the first portion 50A of the terminal member 27 exposed from the lower surface 30B of the step portion 30 using solder 903 or a conductive adhesive.

[0416] In another embodiment, the first portion 50A of the terminal member 27 may be disposed on or coupled to the upper surface 30A of the step portion 30 .

[0417] The first portion 50A of the terminal member 27 may be disposed lower than the second circuit board 250. For example, the first portion 50A of the terminal member 27 may be disposed lower than the lower surface of the second circuit board 250.

[0418] A portion of the extension 50B may be connected to the first portion 50A. Another portion of the extension 50B may be exposed from the first surface 210A of the base 210, and the exposed other portion of the extension 50B may be attached to the pads (Q1 to Q6) of the second circuit board 250 by solder or a conductive adhesive. For example, the base 210 may expose the second portion 51A of the terminal member 27. For example, referring to Figure 8 , an opening 29 may be formed in the first surface 210A of the base 210 to expose the second portion 51A of the terminal member 27. For example, openings 29A to 29F may be formed at the first surface 210A of the base 210 to expose the second portions 51A of the terminals 27A to 27F of the terminal member 27.

[0419] Reference Fig.9cAnother portion of the exposed extension portion 50B of each of the terminals 27A to 27F may be disposed adjacent to a corresponding one of the pads Q1 to Q6. For example, the extension portion 50B may include at least one bent portion or folded portion.

[0420] For example, the width (or area) of the second portion 51A may be smaller than the width (or area) of the first portion 50A. The width (or area) of the third portion 51B may be smaller than the width (or area) of the first portion 50A. For example, the third portion 51B may include a portion having a width smaller than the width of the second portion 51A.

[0421] exist Fig.15 In the embodiment, the plurality of terminals 27A to 27F are spaced apart from each other, but in another embodiment, two or more of the plurality of terminals may be connected to each other or formed as one body.

[0422] In the embodiment, since the first portion 50A of the terminal member 27 combined with the support member 220 is set lower than the lower surface of the second circuit board 250, the length of the support member 220 in the optical axis direction can be increased. As the length of the support member 220 increases, the resistance of the support member 220 can be increased, and the intensity of the current flowing through the support member 220 can be reduced. Therefore, in the embodiment, the reduction in the reliability of the OIS operation due to the reduction in the OIS wire diameter in order to reduce power consumption can be prevented.

[0423] exist Figure 2 In the embodiment of the present invention, the second coil 230 includes three coil units, but in the embodiment where the magnet 130 includes four magnet units, the second coil 230 may include four coil units. Two of the four coil units may be disposed opposite to each other in the X-axis direction perpendicular to the optical axis (e.g., the Z-axis), and the remaining two of the four coil units may be disposed opposite to each other in the Y-axis direction.

[0424] exist Figure 2 In the embodiment of the present invention, the second coil 230 is disposed below the second circuit board 250, but in another embodiment, the second coil may be disposed on the second circuit board 250. For example, in another embodiment, the second coil may be disposed below the housing 140 and / or the bobbin 110. For example, in another embodiment, the second coil may be in the form of a coil block formed by an FP (fine pattern) coil. Alternatively, the second coil may include a circuit member having a hollow portion (or hole) corresponding to the hollow portion 24A of the circuit board 250 and a plurality of coil units formed on the circuit member. Here, the circuit member may be expressed as a "substrate", "circuit board" or "coil board".

[0425] The cover member 300 may accommodate the OIS movable unit, the upper elastic member 150 , the lower elastic member 160 , the second coil 230 , the base 210 and the terminal member 27 , the second circuit board 250 , the support member 220 , and the second position sensor 240 in an accommodation space formed together with the base 210 .

[0426] The cover member 300 may have a box form with an opening at the bottom thereof, and include an upper plate 301 and a side plate 302, and the lower portion of the side plate 302 of the cover member 300 is a step 211 of the base 210 that may be coupled. The shape of the upper plate 301 of the cover member 300 may be a polygon, for example, a square or an octagon.

[0427] The cover member may include an opening 303 formed at the upper plate 301 to expose the lens module 400 combined with the bobbin 110 to external light. The material of the cover member 300 may be a non-magnetic material such as SUS to avoid adhesion to the magnet 130. The cover member 300 may be formed of a metal plate, but is not limited thereto, and may also be formed of plastic. In addition, the cover member 300 may be connected to a ground terminal of the second circuit board 250 of the lens driving device or / and a ground portion of the circuit board 800 of the camera device 200. The cover member 300 may block electromagnetic interference (EMI).

[0429] Reference Figures 18 to 20 The damper 88 may be disposed between the housing 140 and the upper elastic member 150 (eg, the first outer frame 152 or the connecting portion 93). The damper 88 may contact, combine or attach to the housing 140 and the upper elastic member 150 (eg, the first outer frame 152 or the connecting portion 93).

[0430] The damper 88 may reduce vibration of the upper elastic member 150. For example, the damper 88 may reduce vibration of the first outer frame 152 or the connection portion 93. For example, when performing an OIS operation, the damper 88 may reduce vibration of the housing 140 coupled to the first outer frame 152. For example, the damper 88 may be spaced apart from the first inner frame 151. For example, the damper 88 may be spaced apart from the first frame connection portion 153. For another example, the damper 88 may be spaced apart from the support member 220. For another example, the damper 88 may be spaced apart from the second coupling portion 92.

[0431] For example, the damper 88 may be disposed at a corner portion 142 of the housing 140. In another embodiment, the damper 88 may be disposed on a side portion 141 of the housing 140.

[0432] For example, the damper 87 may be disposed between the side (or outer side) of the housing 140 and the support member 220 , and may be in contact with, coupled to, or attached to the side (or outer side) of the housing 140 and the support member 220 .

[0433] For example, the damper 87 may be disposed below the damper 88. For example, the uppermost portion of the damper 87 may be disposed below the lowermost portion of the damper 88. For example, the damper 87 may be spaced apart from the damper 88.

[0434] For example, the damper 87 may be spaced apart from the upper elastic member 150. For example, the damper 87 may be spaced apart from the lower elastic member 160. For example, the damper 87 may be spaced apart from the first outer frame 152. For example, the damper 87 may be spaced apart from the second coupling portion 92. For another example, the damper 87 may be spaced apart from one end of the support member 220 coupled to the second coupling portion 92. In addition, for example, the damper 87 may be spaced apart from the terminal member 27. For example, the damper 87 may be spaced apart from the other end of the support member 220 coupled to the terminal member 27. The damper 87 may be disposed between one end of the support member 220 and the other end of the support member 220.

[0435] The damper 87 may be disposed on the protrusion 70 of the housing 140. For example, the damper 87 may be in contact with, coupled to, or attached to the protrusion 70 of the housing 140. For example, the damper 87 may be disposed within the recess 65 of the protrusion 70 of the housing 140. For example, at least a portion of the damper 87 may be disposed within at least one hole 147 of the protrusion 70.

[0436] For example, the damper 87 may be disposed at a corner portion 142 of the housing 140. In another embodiment, the damper 87 may be disposed on a side portion 141 of the housing 140.

[0437] Hereinafter, the position of the damper 87 or the relative position of any structure compared with the damper 87 will be described.

[0438] For example, the damper 87 may be disposed closer to the lower surface 80A of the housing 140 (or the lowest portion of the housing 140) than the upper surface (or the first surface 60A) of the housing 140. In another embodiment, for example, when indicating the relative position of the damper 87, the upper surface of the housing 140 may be the highest portion of the housing 140, and the lower surface of the housing 140 may be the lowest portion of the housing 140.

[0439] For example, a first separation distance D1 between the damper 87 and the lower surface 80A of the housing 140 is smaller than a second separation distance D2 between the damper 87 and the upper surface (or the first surface 60A) of the housing 140 (D1 < D2). For example, the first separation distance D1 is the distance in the optical axis direction between a virtual line (or an extension line) parallel to the lower surface 80A of the housing 140 (or the lowermost part of the housing 140) and the lowermost part of the damper 87. The second separation distance D2 is the distance in the optical axis direction between a virtual line (or an extension line) parallel to the upper surface of the housing 140 (or the first surface 60A) and the uppermost part of the damper 87.

[0440] For example, the damper 87 may be arranged to be closer to the lower elastic member 160 than the upper elastic member 150. For example, a third separation distance in the optical axis direction between the damper 87 and the lower elastic member 160 is smaller than a fourth separation distance in the optical axis direction between the damper 87 and the upper elastic member 150 (e.g., the second coupling part 92). For example, the third separation distance may be the distance in the optical axis direction between a virtual line (or an extension line) parallel to the upper surface of the lower elastic member 160 and the lowermost part of the damper 87. For example, the fourth separation distance may be the distance in the optical axis direction between the uppermost part of the damper 87 and the lower surface of the upper elastic member 150 (e.g., the second coupling part 92).

[0441] For example, the damper 87 is arranged to be closer to the second coupling part 148 of the housing 140 coupled to the second outer frame 162 than the first coupling part 143 of the housing 140 coupled to the first outer frame 152.

[0442] For example, a fifth separation distance in the optical axis direction between the damper 87 and the second coupling part 148 of the housing 140 is smaller than a sixth separation distance in the optical axis direction between the damper 87 and the first coupling part 143. For example, the fifth separation distance may be the distance in the optical axis direction between the lowermost part of the damper 87 and a virtual line (or an extension line) parallel to the lowermost part of the first coupling part 143. For example, the sixth separation distance may be the distance in the optical axis direction between the uppermost part of the damper 87 and a virtual line (or an extension line) parallel to the uppermost part of the first coupling part 143.

[0443] For example, the damper 87 is arranged to be closer to the lower surface 80A of the housing 140 (or the lowermost part of the housing 140) than one end of the support member 220 coupled to the second coupling part 92 of the first outer frame 152. For example, the first separation distance D1 in the optical axis direction between the damper 87 and the lower surface 80A of the housing 140 (or the lowermost part of the housing 140) may be smaller than the separation distance in the optical axis direction between the damper 87 and one end of the support member 220. Here, one end of the support member 220 may be a part of the support member 220 coupled to the second coupling part 92.

[0444] In addition, for example, the damper 87 may be disposed closer to the lower elastic member 160 than one end of the support member 220 coupled to the second coupling portion 92 of the first outer frame 152 .

[0445] For example, the third separation distance between the damper 87 and the lower elastic member 160 in the optical axis direction may be smaller than the separation distance between the damper 87 and one end of the supporting member 220 in the optical axis direction.

[0446] For example, the damper 87 may overlap with the second coupling portion 92 in the optical axis direction. For example, the damper 87 may overlap with one end of the support member 220 coupled to the second coupling portion 92 in the optical axis direction. The second coupling portion 92 may overlap with the terminal member 27 (or the first portion 50A) in the optical axis direction.

[0447] For example, the damper 87 may not overlap with the damper 88 in the optical axis direction. For example, the damper 87 may not overlap with the damper 88 in the direction perpendicular to the optical axis. The damper 87 may overlap with at least a portion of the base 210 in the optical axis direction. In another embodiment, the damper 87 may not overlap with the base 210 in the optical axis direction.

[0448] For example, the protrusion 70 of the housing 140 may be arranged to be closer to the lower surface 80A of the housing 140 (or the lowest part of the housing 140) than the upper surface (or the first surface 60A) of the housing 140. For example, the first distance D3 between the lower surface 80A of the housing 140 (or the lowest part of the housing 140) and the protrusion 70 in the optical axis direction may be smaller than the second distance D4 between the upper surface (or the first surface 60A) of the housing 140 and the protrusion 70 in the optical axis direction. For example, the first distance D3 is the distance between the lowest part (or the lower surface) of the protrusion 70 and an imaginary line (or an extended line) parallel to the lower surface 80A of the housing 140 (or the lowest part of the housing 140) in the optical axis direction. For example, the second distance D4 is the distance between the imaginary line (or an extended line) parallel to the upper surface (or the first surface 60A) of the housing 140 and the upper surface 60B of the protrusion 70 in the optical axis direction.

[0449] For example, the first distance D3 may be greater than or equal to 0 and less than or equal to 0.8 [mm]. Alternatively, for example, the first distance D3 may be 0.45 [mm] to 0.65 [mm]. Alternatively, for example, the first distance D3 may be 0.5 [mm] to 0.6 [mm]. When the first distance D3 is 0, the height of the lower surface (or the lowest portion) of the protrusion 70 may be the same as the height of the lower surface 80A of the housing 140 (or the lowest portion of the housing 140). When the first distance D3 is 0, the damper 87 may be disposed close to the center position of the support member 220, the damping force of the damper 87 may be increased, and the stabilization time associated with the vibration of the housing may be reduced.

[0450] When the first distance D3 is greater than 0.75, the damper 87 can be set close to the joint between the upper elastic member 150 and the support member 220 (for example, 902, which is a fixed portion), and the damping force of the damper 87 can be reduced, and the reduction in the stabilization time associated with the shell vibration can be minimized.

[0451] For example, the second distance D4 may be greater than or equal to 0.85 [mm] and may be less than the reference value. For example, the reference value may be a value obtained by subtracting the length of the protrusion 70 in the optical axis direction from the height (or length) in the optical axis direction from the upper surface 60A (or first surface) of the housing 140 to the lower surface 80A (or the lowermost portion) of the housing 140.

[0452] For example, the length of the protrusion 70 in the optical axis direction may be 0.3 [mm] to 0.55 [mm]. Alternatively, the length of the protrusion 70 in the optical axis direction may be 0.4 [mm] to 0.5 [mm]. Alternatively, the length of the protrusion 70 in the optical axis direction may be 0.45 [mm] to 0.5 [mm].

[0453] For example, the second distance D4 may be 0.9 [mm] to 1.2 [mm]. Alternatively, for example, the second distance D4 may be 0.95 [mm] to 1.15 [mm]. When the second distance D4 is less than 0.85 [mm], the damper 87 may be disposed close to the joint (e.g., 902, which is the fixing portion) between the upper elastic member 150 and the support member 220, thereby reducing the damping force of the damper 87 and minimizing the reduction in the stabilization time associated with the vibration of the housing.

[0454] For example, the difference between the first distance D3 and the second distance D4 may be 0.05 [mm] to 1.45 [mm]. Alternatively, for example, the difference between the first distance D3 and the second distance D4 may be 0.3 [mm] to 0.8 [mm]. Alternatively, for example, the difference between the first distance D3 and the second distance D4 may be 0.45 [mm] to 0.55 [mm].

[0455] For example, the upper surface 60B of the protrusion 70 of the housing 150 is closer to the upper surface (or the first surface 60A) of the housing 140 than the lower surface 80A of the housing 140 (or the lowermost part of the housing 140). For example, the separation distance in the optical axis direction between the upper surface 60B of the protrusion 70 and the lower surface 80A of the housing 140 (or the lowermost part of the housing 140) may be smaller than the separation distance in the optical axis direction between the upper surface 60B of the protrusion 70 and the upper surface (or the first surface 60A) of the housing 140. In other embodiments, the former may be greater than or equal to the latter.

[0456] For example, the separation distance D5 in the optical axis direction between the damper 87 and one end of the support member 220 may be smaller than the separation distance D6 in the optical axis direction between the damper 87 and the other end of the support member 220 (D5 < D6). For example, one end of the support member 220 may be a part of the support member 220 that is joined to the upper elastic member 150 (e.g., the second joint portion 92) by solder 902. For example, the other end of the support member 220 may be another part of the support member 220 that is joined to the terminal member 27 (e.g., the first portion 50A) by solder 903. In another embodiment, the separation distance in the optical axis direction between the damper 87 and one end of the support member 220 may be greater than or equal to the separation distance in the optical axis direction between the damper 87 and the other end of the support member 220.

[0457] For example, the damper 87 may be arranged closer to the lower surface of the magnet 130 than the upper surface or the first surface 60A of the housing 140. For example, the damper 87 may be arranged closer to the upper surface of the magnet 130 than the lower surface of the magnet 130. In another embodiment, the damper 87 may be arranged closer to the lower surface of the magnet 130 than the upper surface of the magnet 130. In another embodiment, the separation distance in the optical axis direction between the upper surface of the magnet 130 and the damper 87 may be equal to the separation distance between the lower surface of the magnet 130 and the damper 87.

[0458] For example, the damper 87 may be arranged closer to the lower surface 80A of the housing 140 than the damper 88. For example, the first separation distance D1 between the damper 87 and the lower surface 80A of the housing 140 may be smaller than the separation distance D11 between the damper 87 and the damper 88 (D1 < D11). For example, D11 may be the distance in the optical axis direction between an imaginary line (or an extension line) parallel to the lower surface (or the lowermost part) of the damper 88 and the uppermost part of the damper 87.

[0459] In another embodiment, the damper 87 may be disposed closer to the damper 88 than the lower surface 80A of the housing 140. In another embodiment, D11 and D1 may be equal to each other.

[0460] For example, the volume of damper 87 may be smaller than the volume of damper 88 , and in other embodiments, the former may be greater than or equal to the latter.

[0461] Furthermore, for example, the contact area between the damper 87 and the housing 140 may be smaller than the contact area between the damper 88 and the housing 140, and in other embodiments, the former may be greater than or equal to the latter.

[0462] The lens driving device according to the comparative example may include a single damper attached to the support member 220 and the upper elastic member 150 (e.g., the second coupling portion 92) together, instead of the damper 87. In the damper according to the comparative example, the damper restraining force applied from the single damper to the support member 220 and the damper restraining force applied from the single damper to the upper elastic member 150 may be mixed. In this way, when the damper restraining force applied to the support member 220 and the damper restraining force applied to the upper elastic member 150 are mixed, it is difficult to accurately control the vibration of the housing 140 during the OIS operation.

[0463] In an embodiment, the damper 88 and the damper 87 are provided to be spaced apart from each other, the damper 88 may control the damper restraining force for the upper elastic member 150, and the damper 87 may control the damper restraining force for the support member 220. That is, in an embodiment, the damper restraining force for each of the upper elastic member 150 and the support member 220 may be independently and individually controlled, and thus, the vibration of the housing 140 may be accurately controlled during the OIS operation.

[0464] Additionally, in an embodiment, the vibration absorption effect of the housing 140 during OIS operation may be maximized by using two independently separated dampers 88 and 87 .

[0465] In addition, in the embodiment, since the damper 87 is disposed between the protrusion 70 of the housing 140 and the support member 220, the contact area between the damper 87 and the housing 140 can be increased, and thus, the vibration reduction effect of the housing 140 can be increased.

[0466] In addition, in an embodiment, since the damper 87 is disposed in a recess 65 formed in the protrusion 70 of the shell 140, the damper 87 can be easily attached to or accommodated in the shell 140, and the damper 87 can be prevented from being separated from the shell 140 due to vibration of the shell 40.

[0467] In addition, in an embodiment, since the damper 87 is disposed in at least one hole 147 formed in the protrusion 70 of the shell 140, the damper 87 can be easily and firmly attached to the support member 220 passing through the hole 147 and the hole 147 of the shell 140, and the damper 87 can be prevented from being separated from the shell 140 due to vibration of the shell 140.

[0468] The damping force of the damper and / or the settling time of the housing vibration may vary based on the relative arrangement positions of the damper and the end of the support member coupled to the upper elastic member. That is, the damping force of the damper for vibration reduction of the housing may vary according to the height at which the damper is disposed between one end of the support member and the other end of the support member, and this may result in a change in the settling time.

[0469] From the perspective of controlling the OIS operation, it may be necessary to control the damping force of the damper and the stabilization time of the housing vibration under the condition that a predetermined driving force is provided.

[0470] Unlike the comparative example in which the damper is disposed closer to one end of the support member coupled to the upper elastic member, in the embodiment, the damper 87 may be disposed closer to the lower surface of the housing 140 than the upper surface of the housing 140. Fig. 20 As shown, the damper 87 can be disposed close to the center of the support member 220, and under the condition of providing a predetermined driving force for the OIS operation, the damping force of the damper in the embodiment is greater than the damping force of the damper in the comparative example, and the stabilization time of the housing vibration in the embodiment can be further reduced. That is, in the embodiment, the damping force of the damper 87 can be increased, and the stabilization time during the OIS operation can be reduced.

[0471] Fig.21 is a cross-sectional view of a lens driving device 100 - 1 according to another embodiment.

[0472] Reference Fig.21 Compared with the lens driving device 100, in the lens driving device 100-1, the arrangement of the second coil 230A and the connection of the other end of the supporting member 220 may be different. Except for the arrangement of the second coil 230A and the connection of the other end of the supporting member 220, the description of the lens driving device 100 may be applied or applied by analogy to the lens driving device 100-1.

[0473] In the lens driving device 100-1, the circuit board 250-1 may be disposed on the base 210-1. The second coil 230A may be disposed on the circuit board 250-1 corresponding to, facing or overlapping the magnet 130 in the optical axis direction, and may be conductively connected to the circuit board 250-1. For example, the second coil 230A may include a plurality of coil units corresponding to a plurality of magnet units of the magnet 130. For example, the second coil 230A may be formed on a circuit member 231 separated from the circuit board 250-1. In another embodiment, the second coil 230A may be in the form of a patterned coil formed on the circuit board 250-1. Alternatively, in another embodiment, the circuit member 231 may be omitted, and the second coil 230A may be implemented in the form of a ring coil block separated from the circuit board 250. A dodge portion may be formed in the circuit member 231 on which the second coil 230A is disposed to avoid spatial interference with the support member 220, and the dodge portion may be a chamfer, a groove or a through hole. In addition to the description of the arrangement of the second coil 230 , the description of the second coil 230 may be applied or analogically applied to the second coil 230A.

[0474] The second position sensor 24001 may be disposed on the circuit board 250-1 and conductively connected to the circuit board 240-1. The description of the second position sensor 240 may be applied or analogically applied to the second position sensor 240-1.

[0475] In the lens driving device 100-1, the terminal member 27 may be omitted, and the other end of the support member 220 may be combined with the circuit board 250-1 by solder 903 or a conductive adhesive, and may be conductively connected to the circuit board 250-1. For example, the other end of the support member 220 may be combined with the lower surface of the circuit board 250-1 by solder 903. The circuit board 250-1 may include a pad 25-1 that is combined with the other end of the support member 220 by solder 903 and conductively connected. The circuit board 250-1 may include an avoidance portion, such as a through hole or a groove, to avoid spatial interference with the support member 220.

[0476] Figures 18 to 20 The descriptions related to D1 to D4 can be applied or applied by analogy to Fig.21 Embodiment of the invention.

[0477] For example, the damper 87 may be disposed closer to the second coil 230A than the upper surface of the housing 140 or the first surface 60A of the housing 140. For example, the seventh separation distance D7 between the damper 87 and the upper surface of the second coil 230A is less than the second separation distance D2 (D7) between the damper 87 and the upper surface of the housing 140 (or the first surface 60A). <D2)。

[0478] For example, the seventh separation distance D7 is the distance in the optical axis direction between a virtual line (or an extension line) parallel to the upper surface of the second coil 230A (or the upper surface of the circuit member 231) and the lowermost part of the damper 87. In other embodiments, D7 may be greater than or equal to D2.

[0479] For example, the damper 87 may be arranged closer to the second coil 230A than the upper elastic member 150. For example, the seventh separation distance D7 between the damper 87 and the second coil 230A is less than the fourth separation distance in the optical axis direction between the damper 87 and the upper elastic member 150 (e.g., the second coupling part 92).

[0480] For example, the separation distance D8 between the damper 87 and the second circuit board 250-1 is greater than the second separation distance (D2) between the damper 87 and the upper surface (or the first surface 60A) of the housing 140 (D8>D2). In other embodiments, D8 may be less than or equal to D2.

[0481] For example, the separation distance D5 in the optical axis direction between the damper 87 and one end of the support member 220 may be less than the separation distance D9 in the optical axis direction between the damper 87 and the other end of the support member 220 (D5<D9). Here, the other end of the support member 220 may be another part where the circuit board 250-1 is coupled to the support member 220 using solder 903. In another embodiment, the separation distance in the optical axis direction between the damper 87 and one end of the support member 220 may be greater than or equal to the separation distance in the optical axis direction between the damper 87 and the other end of the support member 220.

[0482] As described above, in the embodiment, two dampers 88 and 87 spaced apart from each other are provided to absorb and control the vibration of the housing 140 during OIS operation, and the binding force (or damping effect) of the dampers on the elastic member 150 and the support member 220 can be independently controlled. Therefore, the vibration of the housing 140 during OIS operation can be precisely controlled. In addition, in the embodiment, the resonance frequency based on the vibration of the housing 140 during OIS operation, such as the first resonance frequency or the second resonance frequency, can be precisely controlled.
