[0077] 1 and 2, the lens driving device 100 includes a bobbin 110, a first coil 120, a first magnet 130, a housing 140, an upper elastic member 150, a lower elastic member 160, a base 210, a support member 220, a second coil 230, and a circuit board 250.

[0078] In addition, for AF feedback driving, the lens driving device 100 may further include a first position sensor 170, a circuit board 190, and a second magnet 180.

[0079] In addition, the lens driving device 100 may further include a second position sensor 240 to perform a camera shake correction function.

[0080] In addition, the lens driving device 100 may further include a third magnet 185 and a cover member 300.

[0081] In addition, the lens driving device 100 may further include a capacitor 195 mounted on the circuit board 190 .

[0082] First, the bobbin 110 will be described. The bobbin 110 is disposed inside the housing 140 and can move in an optical axis (OA) direction or a first direction (eg, Z-axis direction) by electromagnetic interaction between the first coil 120 and the first magnet 130.

[0083] 3A shows a perspective view of the bobbin 110, the second magnet 180 and the third magnet 185 shown in FIG. 1, and FIG. 3B shows the first coil 120 coupled to the bobbin 110. As shown in FIG.

[0084] 3A and 3B, the bobbin 110 may have an opening for mounting a lens or a lens barrel. For example, the opening of the bobbin 110 may be a through hole passing through the bobbin 110 in the optical axis direction, and the shape of the opening of the bobbin 110 may be, but is not limited to, a circle, an ellipse, or a polygon.

[0085] A lens is directly attached to the opening of the bobbin 110, but is not limited thereto, and in other embodiments, a lens barrel to which at least one lens is attached or coupled may be coupled or attached to the opening of the bobbin 110. The lens or lens barrel may be coupled to the inner peripheral surface of the bobbin 110 in various ways.

[0086] The bobbin 110 may include first sides 110b-1 and second sides 110b-2 spaced apart from each other, and each of the second sides 110b-2 may connect two adjacent first sides to each other. For example, the horizontal or lateral length of each of the first sides 110b-1 of the bobbin 110 may be different from the horizontal or lateral length of each of the second sides 110b-2. For example, the horizontal length of the first side 110b-1 may be greater than the horizontal length of the second side 110b-2, but is not limited thereto, and in other embodiments, the former may be equal to or less than the latter.

[0087] The bobbin 110 may include a protrusion 115 disposed on an outer surface.

[0088] For example, but not limited to, the protrusion 115 is disposed on the outer surface of the second side portion 110b-2 of the bobbin 110. The protrusion 115 can protrude in a direction parallel to a straight line that passes through the center of the opening of the bobbin 110 and is perpendicular to the optical axis, but is not limited to this.

[0089] The protrusion 115 of the bobbin 110 can be inserted or positioned within the groove 25a of the housing 140 in correspondence with the groove 25a of the housing 140, thereby suppressing or preventing the bobbin 110 from rotating more than a certain range around the optical axis.

[0090] In addition, the protrusion 115 can act as a stopper that suppresses or prevents the lower surface of the bobbin 110 from directly colliding with the base 210, the second coil 230, or the circuit board 250 even if the bobbin 110 moves more than a specified range in the optical axis direction (e.g., the direction from the upper elastic member 150 toward the lower elastic member 160) due to an external impact, etc.

[0091] A first escape groove 112a may be provided on the upper surface of the bobbin 110 to avoid spatial interference with the first frame connecting portion 153 of the upper elastic member 150. For example, the first escape groove 112a may be disposed on the second side portion 110b-2 of the bobbin 110, but is not limited thereto.

[0092] A guide portion 111 for guiding the installation position of the upper elastic member 150 may be provided on the upper surface of the bobbin 110. For example, as illustrated in Fig. 3A, the guide portion 111 of the bobbin 110 may be disposed in a first escape groove 112a to guide the path through which the frame connecting portion 153 of the upper elastic member 150 passes. For example, the guide portion 111 may protrude in the optical axis direction from a bottom surface of the first escape groove 112a.

[0093] In addition, a damper may be disposed between the guide portion 111 and the first frame connecting portion 153 of the upper elastic member 150.

[0094] The bobbin 110 may include a stopper 116 protruding from a top surface.

[0095] The stopper 116 of the bobbin 110 can prevent the top surface of the bobbin 110 from directly colliding with the inside of the top plate of the cover member 300 even if the bobbin 110 moves beyond a specified range due to an external impact or the like when the bobbin 110 moves in a first direction for the autofocusing function.

[0096] The bobbin 110 may include a first coupling portion 113 formed on the upper portion or upper surface of the bobbin 110 to be coupled and fixed to the upper elastic member 150. For example, the first coupling portion 113 of the bobbin 110 in Fig. 3A is in the form of a protrusion, but is not limited thereto, and in other embodiments, the first coupling portion 113 of the bobbin 110 may be in the form of a groove or a flat surface.

[0097] In addition, the bobbin 110 may include a second coupling portion 117 formed on the lower portion or bottom surface of the bobbin 110 to be coupled and fixed to the lower elastic member 160. In FIG. 3B, the second coupling portion 117 of the bobbin 110 is in the form of a protrusion, but is not limited thereto, and in other embodiments, the second coupling portion of the bobbin 110 may be in the form of a groove or a flat surface.

[0098] A seating groove 105 in which the first coil 120 is seated, inserted or disposed may be provided on an outer surface of the bobbin 110. The seating groove 105 may have a groove structure recessed from the outer surfaces of the first and second side portions 110b-1 and 110b-2 of the bobbin 110, and may have a shape that matches the shape of the first coil 120, such as a closed curve shape (e.g., a ring shape).

[0099] In addition, when the coil 120 is connected to the lower elastic members 160-1 and 160-2, in order to prevent the coil 120 from coming off and to guide both ends of the coil 120, guide grooves 116a and 116b may be provided on the lower surfaces of the two first side portions 110b-1 or the two second side portions 110b-2 located on opposite sides of the bobbin 110.

[0100] In addition, the bobbin 110 may have a seating groove 180a on an outer surface thereof in which the second magnet 180 is seated, inserted, fixed or disposed.

[0101] The seating groove 180a of the bobbin 110 may have a structure recessed from the outer surface of the bobbin 110, and may have an opening on at least one of the upper surface or the lower surface of the bobbin 110, but is not limited thereto.

[0102] In addition, a seating groove 185a may be provided on the outer surface of the bobbin 110 for seating, inserting, fixing or disposing the third magnet 185 therein.

[0103] The seating groove 185a of the bobbin 110 may have a structure recessed from the outer surface of the bobbin 110, and may have an opening on at least one of the upper surface or the lower surface of the bobbin 110, but is not limited thereto.

[0104] Each of the seating grooves 180a, 185a of the bobbin 110 may be located above the seating groove 105 in which the first coil 120 is disposed, and may be connected or in contact with the seating groove 105, but is not limited thereto, and in other embodiments, the two may be spaced apart from each other.

[0105] The seating groove 180a of the bobbin 110 may be provided on one of the first sides 110b-1 of the bobbin 110, and the seating groove 185a of the bobbin 110 may be provided on the other of the first sides 110b-2 of the bobbin 110.

[0106] For example, the seating grooves 180a, 185a may be disposed on two first sides of the bobbin 110 facing each other or on two first sides located on opposite sides.

[0107] The second magnet 180 and the third magnet 185 are disposed in the seating grooves 180a, 185a provided on the two first sides located on opposite sides of the bobbin 110, so that the weights of the second magnet 180 and the third magnet 185 can be balanced, and the influence of the AF driving force due to the magnetic field interference between the first magnet 130 and the second magnet 180 and the influence of the AF driving force due to the magnetic field interference between the first magnet 130 and the third magnet 185 can be offset each other, thereby improving the accuracy of the AF (Auto Focusing) drive in this embodiment.

[0108] The bobbin 110 may have a screw thread 11 on its inner circumferential surface for coupling with a lens or a lens barrel. The screw thread 11 may be formed on the inner circumferential surface of the bobbin 110 in a state where the bobbin 110 is fixed by a jig or the like, and the bobbin 110 may have jig fixing grooves 15a and 15b on its upper surface. For example, the jig fixing grooves 15a and 15b may be provided on the upper surfaces of two first side portions 110b-1 or two second side portions 110b-1 located on opposite sides of the bobbin 110, but are not limited thereto. The jig fixing grooves 15a and 15b may function as a foreign matter collector for collecting foreign matter.

[0109] Next, the first coil 120 will be described. The first coil 120 is disposed on the outer surface of the bobbin 110 . The first coil 120 is disposed below the second and third magnets 180, 185, but is not limited thereto. For example, the first coil 120 is disposed below the protruding portion 115 of the bobbin 110, but is not limited thereto.

[0110] For example, but not limited to, the first coil 120 does not overlap the second and third magnets 180, 185 in a direction perpendicular to the optical axis. In other embodiments, the first coil may overlap at least a portion of each of the second and third magnets 180, 185 in a direction perpendicular to the optical axis.

[0111] For example, the first coil 120 may be positioned in the mounting groove 105 of the bobbin 110, the second magnet 180 may be inserted or positioned in the mounting groove 180a of the bobbin 110, and the third magnet 185 may be inserted or positioned in the mounting groove 185a of the bobbin 110.

[0112] Each of the second magnet 180 and the third magnet 185 arranged on the bobbin 110 may be separated from the first coil 120 in the optical axis (OA) direction, but is not limited to this. In other embodiments, each of the second magnet 180 and the third magnet 185 arranged on the bobbin 110 may be in contact with the first coil 120 or overlap with a portion of the first coil 120 in a direction perpendicular to the optical axis.

[0113] The first coil 120 may cover the outer surface of the bobbin 110 in a direction rotating around the optical axis (OA). For example, the first coil 120 may have a closed curve wound around the outer surface of the bobbin 110, for example, a ring shape.

[0114] The first coil 120 may be wound directly on the outer surface of the bobbin 110, but is not limited to this. According to other embodiments, the first coil 120 may be wound on the bobbin 110 using a coil ring, or may be provided as an angular ring-shaped coil block.

[0115] A power source or a drive signal may be provided to the first coil 120. The power source or drive signal provided to the first coil 120 may be a DC signal or an AC signal, or may include a DC signal and an AC signal, and may be in the form of a voltage or a current.

[0116] When a driving signal (e.g., a driving current) is supplied, the first coil 120 can generate an electromagnetic force through electromagnetic interaction with the first magnet 130, and the bobbin 110 can move in the optical axis (OA) direction due to the generated electromagnetic force.

[0117] At the initial position of the AF movable part, the bobbin 110 can move in the upward or downward direction, which is called bidirectional driving of the AF movable part.

[0118] Or, at the initial position of the AF movable part, the bobbin 110 can move in the upward direction, which is called unidirectional driving of the AF movable part.

[0119] In the initial position of the AF movable part, the first coil 120 may be arranged to correspond to or overlap with the first magnet 130 arranged in the housing 140 in a direction perpendicular to the optical axis (OA) and parallel to a line passing through the optical axis.

[0120] For example, the AF movable part may include a bobbin 110 and a configuration (e.g., a first coil 120, a second and a third magnet 180, 185) coupled to the bobbin 110. The AF movable part may further include a lens or a lens barrel coupled to the bobbin 110.

[0121] Furthermore, the initial position of the AF movable part may be the initial position of the AF movable part when no power is applied to the first coil 120, or it may be the position where the AF movable part is placed as the upper and lower elastic members 150, 160 are elastically deformed solely by the weight of the AF movable part.

[0122] In addition, the initial position of the bobbin 110 may be a position where the AF movable part is located when gravity acts from the bobbin 110 toward the base 210, or conversely, when gravity acts from the base 210 toward the bobbin 110.

[0123] Next, the second and third magnets 180, 185 will be described.

[0124] The second magnet 180 may be referred to as a "sensing magnet" in that it provides a magnetic field for the first position sensor 170 to sense, and the third magnet 185 may be referred to as a "balancing magnet" in that it offsets the magnetic field effect of the sensing magnet 180 and balances the weight with the sensing magnet 180.

[0125] The second magnet 180 may be disposed in the seating groove 180a of the bobbin 110 and disposed to face the first position sensor 170. For example, but not limited to, the second magnet 180 may overlap the first position sensor 170 in a direction perpendicular to the optical axis and parallel to a line passing through the optical axis at the initial position of the bobbin 110. In other embodiments, the second magnet 180 and the first position sensor 170 may not overlap in a direction perpendicular to the optical axis and parallel to a line passing through the optical axis at the initial position of the bobbin 110.

[0126] A portion of any one of the surfaces of the second magnet 180 facing the first position sensor 170 may be exposed from the seating groove 180a, but is not limited to this, and in other embodiments, a portion of any one of the surfaces of the second magnet 180 facing the first position sensor 170 may not be exposed from the seating groove 180a.

[0127] For example, each of the second and third magnets 180, 185 can be an anodized magnet including two north poles and two south poles or a four-pole magnet.

[0128] Each of the second and third magnets 180, 185 may include a first magnet portion 17a, a second magnet portion 17b, and a partition wall 17c disposed between the first magnet portion 17a and the second magnet portion 17b. Here, the partition wall 17c may also be expressed as a "non-magnetic partition wall."

[0129] The first magnet portion 17a may include an N pole, an S pole, and a first boundary between the N pole and the S pole. The first boundary is a portion that is substantially non-magnetic and may include a section with almost no polarity, and may be a naturally occurring portion that forms a magnet with one N pole and one S pole.

[0130] The second magnet portion 17b may include an N pole, an S pole, and a second interface between the N pole and the S pole. The second interface may be a portion that is substantially non-magnetic and may include a section with almost no polarity, and may be a naturally occurring portion that forms a magnet with one N pole and one S pole.

[0131] The partition 17c separates or isolates the first magnet part 17a and the second magnet part 17b and may be a part that is substantially non-magnetic and has almost no polarity. For example, the partition may be a non-magnetic material or air. The non-magnetic partition may be referred to as a "neutral zone" or a "neutral area."

[0132] The partition wall 17c is a portion that is artificially formed when the first magnet portion 17a and the second magnet portion 17b are magnetized, and the width of the partition wall 17c may be greater than the width of the first boundary portion (or the width of the second boundary portion). Here, the width of the partition wall 17c may be the length in the direction from the first magnet portion 17a toward the second magnet portion 17b. The width of the first boundary portion (or the second boundary portion) may be the length of the first boundary portion in the direction from the north pole to the south pole of each of the first and second magnet portions 17a, 17b.

[0133] For example, the first magnet portion 17a and the second magnet portion 17b may be disposed to face each other in the optical axis direction. For example, the partition wall 17c may be parallel to a line that passes through the optical axis and perpendicular to the optical axis.

[0134] In another embodiment, each of the second and third magnets may be a monopole magnet having one north pole and one south pole.

[0135] For example, the boundary surface between the north pole and the south pole of each of the second and third magnets 180, 185 disposed on the bobbin 110 may be parallel to a direction perpendicular to the optical axis (OA). For example, the north pole and the south pole of each of the second and third magnets 180, 185 may face each other in the optical axis direction.

[0136] For example, each surface of the second and third magnets 180 and 185 facing the first position sensor 170 is divided into a north pole and a south pole, but is not limited thereto.

[0137] For example, in another embodiment, the interface between the north pole and the south pole of each of the second and third magnets 180, 185 disposed on the bobbin 110 may be parallel to the optical axis (OA).

[0138] The second magnet 180 can move in the optical axis direction together with the bobbin 110, and the first position sensor 170 can sense the magnetic field strength or magnetic force of the second magnet 180 moving in the optical axis direction and output an output signal according to the sensed result.

[0139] For example, the strength of the magnetic field or the magnetic force sensed by the first position sensor 170 may change in response to the displacement of the bobbin 110 in the optical axis direction, and the first position sensor 170 may output an output signal proportional to the strength of the sensed magnetic field, and the displacement of the bobbin 110 in the optical axis direction may be sensed using the output signal of the first position sensor 170.

[0140] Next, the housing 140 will be described. The housing 140 accommodates the bobbin 110 therein, and supports the first magnet 130 , the first position sensor 170 , and the circuit board 190 .

[0141] 4A shows a perspective view of the housing 140, the circuit board 190, the first position sensor 170, and the capacitor 195 shown in FIG. 1, and FIG. 4B shows a combined perspective view of the housing 140, the first magnet 130, the circuit board 190, the first position sensor 170, and the capacitor 195.

[0142] 4A and 4B, the housing 140 may be generally in the shape of a hollow column. For example, the housing 140 may have a polygonal (e.g., rectangular or octagonal) or circular opening, and the opening of the housing 140 may be in the form of a through-hole that penetrates the housing 140 in the optical axis direction.

[0143] The housing 140 may include a number of side portions 141-1 to 141-4 and corner portions 142-1 to 142-4.

[0144] For example, the housing 140 may include first to fourth side portions 141-1 to 141-4 and first to fourth corner portions 142-1 to 142-4 that are spaced apart from one another.

[0145] For example, the first and second sides 141-1, 141-2 of the housing 140 may face or be opposite each other, and the third and fourth sides 141-3, 141-4 of the housing 140 may face or be opposite each other.

[0146] Each of the corner portions 142-1 to 142-4 of the housing 140 can be disposed or positioned between two adjacent side portions (141-1 and 141-2, 141-2 and 141-3, 141-3 and 141-4, 141-4 and 141-1) and can connect the side portions 141-1 to 141-4 to each other.

[0147] For example, the corner portions 142-1 to 142-4 may be located at corners or edges of the housing 140. For example, the number of sides of the housing 140 is four, and the number of corner portions is four, but is not limited thereto, and may be five or more.

[0148] Each of the side portions 141-1 to 141-4 of the housing 140 can be disposed so as to be parallel to a corresponding one of the side plates 302 of the cover member 300.

[0149] For example, sides 141-1 to 141-4 of housing 140 may correspond to or face a first side 110b-1 of bobbin 110, and corners 142-1 to 142-4 of housing 140 may correspond to or face a second side 110b-2 of bobbin 110.

[0150] The first magnets 130 may be disposed or installed at the corners 142-1 to 142-4 of the housing 140.

[0151] For example, the corners or corner portions 142-1 to 142-4 of the housing 140 may be provided with a seating portion 141a or a receiving portion for receiving the magnet 130.

[0152] The seating portion 141a of the housing 140 may be provided at the lower portion or the lower end of at least one of the corner portions 142-1 to 142-4 of the housing 140.

[0153] For example, the seating portion 141a of the housing 140 may be provided on the lower portion or inside the lower end of each of the four corner portions 142-1 to 142-4.

[0154] The seating portion 141a of the housing 140 is formed as a groove having a shape corresponding to the first magnet 130, for example, a concave groove, but is not limited thereto.

[0155] For example, a first opening may be formed on a side of the mounting portion 141a of the housing 140 facing the first coil 120, and a second opening may be formed on a bottom surface of the mounting portion 141a of the housing 140 facing the second coil 230, to facilitate attachment of the first magnet 130.

[0156] For example, the first surface 11a of the first magnet 130 fixed or disposed in the mounting portion 141a of the housing 140 may be exposed through a first opening of the mounting portion 141a. Also, the lower surface of the first magnet 130 fixed or disposed in the mounting portion 141a of the housing 140 may be exposed through a second opening of the mounting portion 141a.

[0157] In order to avoid spatial interference with the first frame connecting portion 153 of the upper elastic member 150, the housing 140 may include escape grooves 41 provided on the upper surfaces of the corner portions 142-1 to 142-4.

[0158] For example, the escape groove 41 of the housing 140 may be recessed from the top surface of the housing 140 and may be located closer to the center of the housing 140 than the stopper 145 or the adhesive injection hole 147. For example, the escape groove 41 may be located on the inside toward the center of the housing 140 based on the stopper 145 of the housing 140, and the adhesive injection holes 146a, 146b may be located on the opposite outside.

[0159] Corner portions 142-1 to 142-4 of housing 140 may be provided with grooves 25a corresponding to or facing protrusions 115 of bobbin 110. Groove portion 25a of housing 140 may be located on seating portion 141a of housing 140. For example, groove portion 25a of housing 140 may be formed on a bottom surface of escape groove 41. For example, the bottom surface of groove portion 25a may be located lower than the bottom surface of escape groove 41, and seating groove 141a of housing 140 may be located lower than the bottom surface of escape groove 41.

[0160] The first magnet 130 is fixed to the seating portion 141a by, but not limited to, an adhesive.

[0161] For example, at least one adhesive injection hole 146a, 146b for injecting an adhesive may be provided in each of the corners 142-1 to 142-4 of the housing 140. The at least one adhesive injection hole 146a, 146b may be recessed from an upper surface of the corners 142-1 to 142-4.

[0162] At least one adhesive injection hole 146a, 146b may include a through hole penetrating the corner portions 142-1 to 142-4, and the adhesive injection holes 146a, 146b may be connected or communicated with the seating groove 141a of the housing 140 and may expose at least a portion of the first magnet 130 (e.g., at least a portion of the upper surface of the magnet 130). Since the adhesive injection holes 146a, 146b expose at least a portion of the first magnet 130 (e.g., at least a portion of the upper surface of the magnet 130), the adhesive may be well applied to the first magnet 130, thereby improving the fixing force between the first magnet 130 and the housing 140.

[0163] The housing 140 may have at least one stopper 147a protruding from the outer surface of the side portions 141-1 to 141-4, and the at least one stopper 147a may prevent the housing 140 from colliding with the side plate 302 of the cover member 300 when the housing 140 moves in a direction perpendicular to the optical axis.

[0164] In order to prevent the lower surface of the housing 140 from colliding with the base 210 and / or the circuit board 250, the housing 140 may further include a stopper (not shown) protruding from the lower surface.

[0165] The housing 140 may have a mounting groove 14a (or seating groove) for accommodating the circuit board 190, a mounting groove 14b (or seating groove) for accommodating the first position sensor 170, and a mounting groove 14c (or seating groove) for accommodating the capacitor 195.

[0166] The mounting groove 14a of the housing 140 may be provided on the upper portion or the upper end of any one of the side portions 141-1 to 141-4 (for example, 141-1) of the housing 140.

[0167] To facilitate mounting of the circuit board 190, the mounting groove 14a of the housing 140 may be in the form of a groove with an open top and sides and a bottom, and may have an opening that opens to the inside of the housing 140. The shape of the mounting groove 14a of the housing 140 may correspond to or match the shape of the circuit board 190.

[0168] The mounting groove 14b of the housing 140 may be provided on an inner surface of the first side portion 141-1 of the housing 140 and may be connected to the mounting groove 14a.

[0169] The mounting groove 14c of the housing 140 may be disposed on one side of the mounting groove 14b, and a protrusion or projection may be provided between the mounting groove 14b and the mounting groove 14c to separate or space the capacitor 195 and the first position sensor 170. This is to reduce the length of the path for the electrical connection between the capacitor 195 and the position sensor 170 by positioning the capacitor 195 and the position sensor 170 adjacent to each other, thereby reducing noise due to an increase in the path.

[0170] The capacitor 195 may be disposed or mounted on the first side 19b of the circuit board 190.

[0171] The capacitor 195 may be in the form of a chip, and in this case, the chip may include a first terminal corresponding to one end of the capacitor 195 and a second terminal corresponding to the other end of the capacitor 195. The capacitor 195 may be referred to as a "capacitive element" or a condenser.

[0172] In other embodiments, a capacitor can be implemented as included in circuit board 190. For example, circuit board 190 may include a capacitor including a first conductive layer, a second conductive layer, and an insulating layer (e.g., a dielectric layer) disposed between the first and second conductive layers.

[0173] The capacitor 195 may be electrically connected in parallel to the first and second terminals B1 and B2 of the circuit board 190 for providing power or a driving signal to the position sensor 170 from the outside.

[0174] Alternatively, the capacitor 195 may be electrically connected in parallel to the terminals of the first position sensor 170 that are electrically connected to the first and second terminals B 1 and B 2 of the circuit board 190 .

[0175] For example, one end of the capacitor 195 (or a first terminal of the capacitor chip) may be electrically connected to a first terminal B1 of the circuit board 190, and the other end of the capacitor 195 (or a terminal of the capacitor chip) may be electrically connected to a second terminal B2 of the circuit board 190.

[0176] The capacitor 195 is electrically connected in parallel to the first and second terminals B1 and B2 of the circuit board 190, and can act as a smoothing circuit to remove ripple components contained in the power signal (GND, VDD) provided to the first position sensor 170 from the outside, thereby providing a stable and constant power signal to the first position sensor 170.

[0177] The capacitor 195 may be electrically connected in parallel to the first and second terminals B1 and B2 of the circuit board 190 to protect the first position sensor 170 from high-frequency noise or ESD that may flow in from the outside.

[0178] In addition, the capacitor 195 can prevent overcurrent caused by external high-frequency noise or ESD from being applied to the first position sensor 170, and can prevent a calibration value for the displacement of the bobbin 110 obtained based on the output signal of the first position sensor 170 from being reset due to the overcurrent.

[0179] In addition, to facilitate mounting of the first position sensor 170, the mounting groove 14b of the housing 140 may have an open top, and to enhance sensing sensitivity, the mounting groove 14b may have an opening that opens to an inner surface of the first side portion 141-1 of the housing 140. The mounting groove 14b of the housing 140 may have a shape that corresponds to or matches the shape of the first position sensor 170.

[0180] For example, the circuit board 190 may be fixed to the mounting groove 14a of the housing 140 by an adhesive member. For example, the adhesive member may be, but is not limited to, epoxy or double-sided tape.

[0181] At the corner portions 142-1 to 142-4 of the housing 140, support members 220-1 to 220-4 may be disposed.

[0182] Holes 147 that form paths through which the support members 220-1 to 220-4 pass may be provided in the corner portions 142-1 to 142-4 of the housing 140. For example, the housing 140 may include holes 147 that pass through the upper portions of the corner portions 142-1 to 142-4.

[0183] In another embodiment, the holes provided in the corners 142-1 to 142-4 of the housing 140 may be recessed from the outer surface of the corners of the housing 140, and at least a portion of the holes may be open to the outer surface of the corners. The number of holes 147 of the housing 140 may be the same as the number of the support members.

[0184] One end of the support member 220 may be connected or bonded to the upper elastic member 150 through the hole 147. For example, one end of the support member 220 may be coupled to a first outer frame of the upper elastic member 150 through the hole 147.

[0185] For example, the diameter of the hole 147 may be gradually increased from the top to the bottom of the housing 140 to facilitate application of the damper, but is not limited thereto, and in other embodiments, the diameter of the hole 147 may be constant.

[0186] In order to form paths through which the support members 220-1 to 220-4 pass as well as to avoid spatial interference between the support members 220-1 to 220-4 and the corner portions 142-1 to 142-4 of the housing 140, escape grooves 148a may be provided on outer surfaces 148 of the corner portions 142-1 to 142-4. The escape grooves 148a may be connected to the holes 147 of the housing 140 and may have a hemispherical or inverse elliptical shape, but are not limited thereto. A lower portion or a lower end of the escape grooves 148a may be connected to the lower surface of the housing 140.

[0187] For example, but not limited to, the diameter of the escape groove 148a may be gradually reduced from the top to the bottom.

[0188] In addition, in order to prevent the housing 140 from directly colliding with the inner surface of the upper plate 301 of the cover member 300, a stopper 145 may be provided on the upper portion, upper end, or upper surface of the housing 140.

[0189] For example, the stoppers 145 are disposed on the upper surfaces of the corner portions 142-1 to 142-4 of the housing 140, but are not limited thereto. In other embodiments, the stoppers 145 may be disposed on the sides of the housing 140.

[0190] In order to prevent the lower surface of the housing 140 from colliding with the base 210 and / or the circuit board 250, a stopper (not shown) may be provided on the lower portion, bottom end, or bottom surface of the housing 140.

[0191] In addition, guide protrusions 146 may be provided at the corners of the upper surface of the corner portions 142-1 to 142-4 of the housing 140 to prevent the dampers from spilling out.

[0192] For example, the hole 147 of the housing 140 may be located between the stopper 145 and a corner (eg, the guide protrusion 146) of the upper surface of the corner portions 142-1 to 142-4 of the housing 140.

[0193] The housing 140 may have at least one first coupling portion 143 on its upper portion, upper end, or upper surface, which is coupled to the first outer frame 152 of the upper elastic member 150 .

[0194] The first coupling portion 143 of the housing 140 may be disposed on at least one of the side portions 141-1 to 141-4 or the corner portions 142-1 to 142-4 of the housing 140.

[0195] A second coupling portion 149 coupled and fixed to a second outer frame 162 of the lower elastic member 160 may be provided on a lower portion, a lower end, or a lower surface of the housing 140 .

[0196] For example, each of the first and second coupling portions 143, 149 of the housing 140 may be in the form of a protrusion, but is not limited thereto, and in other embodiments may be in the form of a groove or a flat surface.

[0197] For example, the first connecting portion 143 of the housing 140 and the hole 152a of the first outer frame 152 of the upper elastic member 150 can be connected using an adhesive or heat sealing, and the second connecting portion 149 of the housing 140 and the hole 162a of the second outer frame 162 of the lower elastic member 160 can be connected.

[0198] In order to avoid spatial interference between the second outer frames 162-1 to 162-3 of the lower elastic member 160 and the portion where the second frame connecting portion 163 meets, at least one lower surface of the side portion 141-1 of the housing 140 may be provided with an escape groove 44a.

[0199] Next, the first magnet 130 will be described. The first magnet 130 may be disposed at at least one of the corners (or corner portions 142-1 to 142-4) of the housing 140. For example, the first magnet 130 may be disposed at each of the corners of the housing 140.

[0200] In the initial position of the AF movable part, the first magnet 130 can be disposed in the housing 140 so as to be perpendicular to the optical axis (OA) and at least partially overlap with the first coil 120 in a direction parallel to a line passing through the optical axis (OA).

[0201] For example, the first magnet 130 may be inserted or disposed in one of the seating portions 141a corresponding to the corner portions 141-1 to 141-4 of the housing 140.

[0202] In another embodiment, the first magnet 130 may be disposed on the outer surfaces of the corner portions 141-1 to 141-4 of the housing 140.

[0203] The first magnet 130 may have a polyhedral shape that is easy to fit in the corners of the housing 140 .

[0204] For example, the area of ​​the first surface 11a of the first magnet 130 may be larger than the area of ​​the second surface 11b. The first surface 11a of each of the first magnets 130 may be a surface facing one of the surfaces of the first coil 120 (or the outer surface of the bobbin 110), and the second surface 11b may be the surface opposite to the first surface 11a.

[0205] For example, the lateral length of the second surface 11b of the first magnet 130 may be smaller than the lateral length of the first surface 11a.

[0206] For example, the lateral direction of the first surface 11a of the first magnet 130 may be a direction perpendicular to the direction from the bottom surface to the top surface of the first magnet 130 on the first surface 11a of the first magnet 130, or a direction perpendicular to the optical axis direction on the first surface 11a of the first magnet 130.

[0207] For example, the lateral direction of the second surface 11b of the first magnet 130 may be a direction perpendicular to the direction from the bottom surface to the top surface of the first magnet 130 on the second surface 11b of the first magnet 130, or a direction perpendicular to the optical axis direction on the second surface 11b of the first magnet 130.

[0208] For example, the first magnet 130 may include a portion whose lateral length gradually decreases from the center of the housing 140 toward the corner portion 142-1, 142-2, 142-3, or 142-4 of the housing 140.

[0209] For example, the first magnet 130 may include a portion where the lateral length of the first magnet 130 decreases from the first surface 11a toward the second surface 11b. For example, the lateral direction of the first magnet 130 may be a direction parallel to the first surface 11a of the first magnet 130.

[0210] The first magnet 130 may include a plurality of magnets 130-1 to 130-4 disposed in a housing 140.

[0211] Each of the multiple magnets 130-1 to 130-4 may be integrally configured and may be arranged such that the first surface 11a facing the first coil 120 is an S pole and the second surface 11b is an N pole. However, this is not limiting, and in other embodiments, each of the multiple magnets 130-1 to 130-4 may be arranged such that the first surface 11a is an N pole and the second surface 11b is an S pole.

[0212] The first magnets may be arranged or installed at the corners of the housing 140 such that at least two of them face each other.

[0213] For example, two pairs of magnets (130-1 and 130-3, 130-2 and 130-4) facing each other in an intersecting manner may be disposed at corner portions 142-1 to 142-4 of the housing 140. In this case, the horizontal planar shape of each of the magnets 130-1 to 130-4 may be a polygon such as a triangle, a pentagon, a hexagon, or a rhombus.

[0214] In other embodiments, a pair of opposing magnets may be disposed at only two opposing corners of the housing 140 .

[0215] In yet other embodiments, the magnets may be disposed on the sides of the housing 140 rather than at the corners of the housing 140. For example, other embodiments may include multiple magnets disposed on the sides of the housing 140, each of which may be shaped as a polyhedron suitable for being disposed on the side of a housing, such as, but not limited to, a regular cube or rectangular hexahedron.

[0216] 5 is a cross-sectional view of the lens driving device 100 shown in FIG. 2 taken along the line AB, and FIG. 6 is a cross-sectional view of the lens driving device 100 shown in FIG. 2 taken along the line CD.

[0217] 5 and 6, each of the second and third magnets 180, 185 may not overlap with the first coil 120 in a direction perpendicular to the optical axis (OA) or in a direction parallel to a line perpendicular to the optical axis and passing through the optical axis, but is not limited thereto. In other embodiments, each of the second and third magnets 180, 185 may overlap with the first coil 120.

[0218] In addition, in the initial position of the AF movable part, the second magnet 180 is overlapped or aligned with the third magnet 185 in a direction perpendicular to the optical axis (OA) or in a direction parallel to a line perpendicular to the optical axis and passing through the optical axis, but is not limited thereto, and in other embodiments, the two may not overlap each other.

[0219] In addition, in the initial position of the AF movable part, the first position sensor 170 overlaps with the second and third magnets 180, 185 in a direction perpendicular to the optical axis (OA) or in a direction parallel to a line perpendicular to the optical axis and passing through the optical axis, but is not limited thereto. In other embodiments, the first position sensor 170 may not overlap with at least one of the second and third magnets 180, 185.

[0220] Furthermore, the first position sensor 170 may not overlap the first magnet 130 in a direction perpendicular to the optical axis (OA) or in a direction parallel to a line perpendicular to and passing through the optical axis.

[0221] For example, the first position sensor 170 may not overlap the first magnet 130 in a direction from the first position sensor 170 toward the first coil 120 or in a direction perpendicular to the optical axis from the first side 141-1 of the housing 140 toward the center of the housing 140.

[0222] Next, the circuit board 190 and the first position sensor 170 will be described.

[0223] The circuit board 190 may be disposed on or coupled to the housing 140 .

[0224] For example, the circuit board 190 may be disposed or coupled to any one side 141-1 of the housing 140. The first position sensor 170 may be disposed or mounted on the circuit board 190. For example, the circuit board 190 may be disposed in the mounting groove 14a of the housing 140.

[0225] For example, the circuit board 190 may be disposed between the first corner portion 142-1 and the second corner portion 142-2 of the housing 140, and the first to fourth terminals B1 to B4 of the circuit board 190 may be electrically connected to the first position sensor 170.

[0226] For example, the circuit board 190 may not overlap an imaginary line connecting a corner portion (e.g., the first corner portion 142-1) (or a corner) of the housing 140 and the optical axis (OA). This is to prevent spatial interference between the support member 220 and the circuit board 190.

[0227] FIG. 7A is an enlarged view of a circuit board 190 and a first position sensor 170, and FIG. 7B is a configuration diagram according to an embodiment of the first position sensor 170 shown in FIG. 7A.

[0228] 7A and 7B, a circuit board 190 may include terminals B1 to B6 for electrically connecting to an external terminal or an external device.

[0229] The first position sensor 170 may be disposed on the first surface 19b of the circuit board 190, and the terminals B1 to B6 are disposed on the second surface 19a of the circuit board 190, but is not limited thereto.

[0230] In other embodiments, the first position sensor 170 and the terminals B1-B6 may be disposed on either the first or second surface of the circuit board 190. In still other embodiments, the first position sensor 170 may be disposed on either the first or second surface of the circuit board 190, and the terminals B1-B6 may be disposed on the remaining one of the first and second surfaces of the circuit board 190.

[0231] Here, the second surface 19a of the circuit board 190 may be the surface opposite to the first surface 19b of the circuit board 190. For example, the second surface 19a of the circuit board 190 may be any one surface of the circuit board 190 facing the bobbin 110.

[0232] The circuit board 190 may include a main body portion S1 and an extension portion S2 located below the main body portion S1. The main body portion S1 may be alternatively referred to as an "upper end portion," and the extension portion S2 may be alternatively referred to as a "lower end portion."

[0233] The extension portion S2 may extend downwardly from the main body portion S1. The main body S1 may be in a form that protrudes from the side surfaces 16a and 16b of the extension S2. For example, the side surfaces 16a and 16b of the extension S2 may be surfaces that connect the first surface 19b and the second surface 19a of the extension S2.

[0234] The main body portion S1 may include a first extension region A1 extending in a direction toward a first corner portion 142-1 of the housing 140 and a second extension region A2 extending in a direction toward a second corner portion 142-2 of the housing 140.

[0235] For example, the first extension region A1 can extend or protrude from the first side surface 16a of the extension portion S2, and the second extension region A2 can extend or protrude from the second side surface 16b of the extension portion S2.

[0236] For example, in FIG. 7A, the lateral length of the first extension region A1 is greater than the lateral length of the second extension region A2, but this is not limited thereto, and in other embodiments, the lateral length of the first extension region A1 may be the same as or smaller than the lateral length of the second extension region A2.

[0237] For example, the lateral length of the main body portion S1 of the circuit board 190 may be greater than the lateral length of the extension portion S2.

[0238] For example, the first to fourth terminals B1 to B4 of the circuit board 190 may be disposed spaced apart from one another on the second surface 19a of the main body portion S1. For example, the four terminals B1 to B4 may be arranged in a line in the lateral direction of the circuit board 190.

[0239] The first terminal B1 and the second terminal B2 may be disposed adjacent to both ends of the body portion S1 of the circuit board 190. That is, the first terminal B1 and the second terminal B2 may be disposed adjacent to a corresponding one of both ends of the body portion S1 of the circuit board 190.

[0240] For example, the first terminal B1 of the circuit board 190 may be disposed at one end (e.g., one end of the upper end) of the circuit board 190, the second terminal B1 may be disposed at the other end of the circuit board 190, the third terminal B3 may be disposed between the first terminal B1 and the second terminal B2, and the fourth terminal B4 may be disposed between the third terminal B3 and the first terminal B1.

[0241] The first terminal B1 of the circuit board 190 can be arranged in a first extension area A1 of the main body portion S1 of the circuit board 190, and the second terminal B2 can be arranged in a second extension area A2 of the main body portion S1 of the circuit board 190.

[0242] The first to fourth terminals B1 to B4 can be disposed so as to be located closer to the upper surface 19c of the circuit board 190 than to the lower surface of the circuit board 190.

[0243] For example, the first to fourth terminals B1 to B4 can be formed so as to contact the second surface 19a and the upper surface 19c of the main body portion S1 of the circuit board 190 that contacts the second surface 19a.

[0244] Furthermore, for example, at least one of the first to fourth terminals B1 to B4 may include a groove 7a or a via formed on the upper surface 19c of the circuit board 190.

[0245] For example, the third terminal B3 and the fourth terminal B4 may include a curved portion recessed from the upper surface 19c of the circuit board 190, such as a semicircular via or groove 7a.

[0246] Such grooves 7a can increase the contact area between the solder and the terminals B3, B4, improving adhesion and solderability.

[0247] The fifth terminal B5 and the sixth terminal B6 of the circuit board 190 may be disposed on the second surface 19a of the extension portion S2 of the circuit board 190 at a distance from each other.

[0248] The circuit board 190 may have a groove 8a or a hole provided between the fifth terminal B5 and the sixth terminal B6. The groove 8a may be recessed from the lower surface of the circuit board 190 and may be open to both the first surface 19b and the second surface 19a of the circuit board 190.

[0249] The distance between the fifth terminal B5 and the sixth terminal B6 may be smaller than the distance between any two adjacent terminals among the first to fourth terminals B1 to B4. However, the groove 8a prevents solder from being formed between the fifth terminal B5 and the sixth terminal B6 during soldering for electrical connection to the outside, thereby preventing an electrical short circuit between the fifth terminal B5 and the sixth terminal B6.

[0250] For example, at least one of the fifth and sixth terminals B5 and B6 may include a groove 7b or a via formed on the lower surface of the circuit board 190.

[0251] For example, the fifth terminal B5 and the sixth terminal B6 may include curved portions recessed from the bottom surface of the circuit board 190, such as semicircular vias or grooves.

[0252] The grooves 7b increase the contact area between the solder and the fifth and sixth terminals B5 and B6, improving adhesion and solderability.

[0253] The circuit board 190 may include a groove 90a disposed between the second terminal B2 and the third terminal B3, and a groove 90b disposed between the first terminal B1 and the fourth terminal B4. Here, the grooves 90a and 90b may be alternatively expressed as "escape grooves."

[0254] Each of the first groove 90a and the second groove 90b may be recessed from the upper surface 19c of the circuit board 190 and may be open to both the first surface 19b and the second surface 19a of the circuit board 190.

[0255] The first groove 90a of the circuit board 190 can be formed to avoid spatial interference with the first outer frame 151 of the third upper elastic unit 150-3, and the second groove 90b of the circuit board 190 can be formed to avoid spatial interference with the first outer frame 151 of the fourth upper elastic unit 150-4.

[0256] For example, the circuit board 190 may be a printed circuit board, or FPCB.

[0257] The circuit board 190 may include a circuit pattern or wiring (not shown) for electrically connecting the first to sixth terminals B1 to B6 and the first position sensor 170.

[0258] The first position sensor 170 can sense the magnetic field or the strength of the magnetic field of the second magnet 180 attached to the bobbin 110 as the bobbin 110 moves, and can output an output signal according to the sensed result.

[0259] The first position sensor 170 may be mounted on a circuit board 190 disposed in the housing 140 and fixed to the housing 140. For example, the first position sensor 170 may be disposed in the mounting groove 14b of the housing 140 and may move together with the housing 140 during image stabilization.

[0260] The first position sensor 170 may be disposed on the first surface 19b of the circuit board 190. In other embodiments, the first position sensor 170 may be disposed on the second surface 19a of the circuit board 190.

[0261] The first position sensor 170 may include a Hall sensor 61 and a Driver 62 .

[0262] For example, the Hall sensor 61 may be made of silicon, and as the ambient temperature increases, the output (VH) of the Hall sensor 61 may increase. For example, the ambient temperature may be the temperature of the lens driving device, for example, the temperature of the circuit board 190, the temperature of the Hall sensor 61, or the temperature of the driver 62.

[0263] In another embodiment, the Hall sensor 61 is made of GaAs, and the output (VH) of the Hall sensor 61 may decrease with respect to the ambient temperature. For example, in another embodiment, the output of the Hall sensor 61 may have a slope of about -0.06% / °C with respect to the ambient temperature.

[0264] The first position sensor 170 may further include a temperature sensing element 63 capable of sensing an ambient temperature. The temperature sensing element 63 may output a temperature sensing signal (Ts) to the driver 62 in accordance with a result of measuring the ambient temperature of the first position sensor 170.

[0265] For example, the Hall sensor 61 of the first position sensor 170 may generate an output (VH) according to the result of sensing the strength of the magnetic force of the second magnet 180. For example, the magnitude of the output of the first position sensor 170 may be proportional to the strength of the magnetic force of the second magnet 180.

[0266] The driver 62 can output a drive signal (dV) for driving the Hall sensor 61 and a drive signal (Id1) for driving the first coil 120.

[0267] For example, the driver 62 can receive a clock signal (SCL), a data signal (SDA), and a power supply signal (VDD, GND) from the control units 830 and 780 using data communication using a protocol, such as I2C communication.

[0268] Here, the first power signal (GND) may be a ground voltage or 0 [V], and the second power signal (VDD) may be a preset voltage for driving the driver 62, and may be a DC voltage and / or an AC voltage, but is not limited thereto.

[0269] The driver 62 can generate a drive signal (dV) for driving the Hall sensor 61 and a drive signal (Id1) for driving the first coil 120 using a clock signal (SCL) and a power supply signal (VDD, GND).

[0270] The first position sensor 170 may include four terminals for transmitting and receiving a clock signal (SCL), a data signal (SDA), and a power supply signal (VDD, GND), and two terminals for providing a driving signal to the first coil 120.

[0271] The driver 62 also receives the output (VH) of the Hall sensor 61 and can transmit a clock signal (SCL) and a data signal (SDA) related to the output (VH) of the Hall sensor 61 to the control units 830 and 780 using data communication using a protocol, for example, I2C communication.

[0272] Furthermore, the driver 62 can receive a temperature sensing signal (Ts) measured by the temperature sensing element 63 and transmit the temperature sensing signal (Ts) to the control unit 830, 780 using data communication using a protocol, for example, I2C communication.

[0273] The control unit 830 , 780 may perform temperature compensation for the output (VH) of the Hall sensor 61 based on the change in the ambient temperature measured by the temperature sensing element 63 of the first position sensor 170 .

[0274] For example, when the drive signal (dV) or bias signal of the Hall sensor 61 is 1 [mA], the output (VH) of the Hall sensor 61 of the first position sensor 170 may be −20 [mV] to +20 [mV].

[0275] In the case of temperature compensation for the output (VH) of the Hall sensor 61 having a negative slope with respect to the ambient temperature change, the output (VH) of the Hall sensor 61 of the first position sensor 170 may be 0 [mV] to +30 [mV].

[0276] When the output of the Hall sensor 61 of the first position sensor 170 is displayed on the xy coordinate system, the output range of the Hall sensor 61 of the first position sensor 170 is set to the first quadrant (e.g., 0 [mV] to +30 [mV]) for the following reason.

[0277] Since the output of the Hall sensor 61 in the first quadrant of the xy coordinate system and the output of the Hall sensor 61 in the third quadrant move in opposite directions according to the change in the ambient temperature, when both the first and third quadrants are used in the AF drive control section, the accuracy and reliability of the Hall sensor are reduced. Therefore, in order to accurately compensate according to the change in the ambient temperature, a certain range of the first quadrant can be set as the output range of the Hall sensor 61 of the first position sensor 170.

[0278] The first position sensor 170 may include first to fourth terminals for two power signals (VDD, GND), a clock signal (SCL), and data (SDA), and fifth and sixth terminals for providing a drive signal to the first coil 120.

[0279] The first to fourth terminals of the first position sensor 170 may be electrically connected to corresponding ones of the first to fourth terminals B1 to B4 of the circuit board 190, and the fifth and sixth terminals of the first position sensor 170 may be electrically connected to corresponding ones of the fifth and sixth terminals B5 and B6 of the circuit board 190.

[0280] In another embodiment, the first position sensor 170 may be realized as a single position detection sensor such as a Hall sensor. In this case, the first position sensor 170 may include two input terminals for receiving a power signal and two output terminals for outputting an output signal, and a driving signal may be provided to the first coil 120 from the outside via the circuit board 250.

[0281] The first to fourth terminals B1 to B4 of the circuit board 190 may be electrically connected to the terminals (251-1 to 251-n, n>1, a natural number) of the circuit board 250 by the upper elastic units 150-1 to 150-4 and the support members 220-1 to 220-4, and thus the first position sensor 170 may be electrically connected to the terminals (251-1 to 251-n, for example, n=4) of the circuit board 250.

[0282] In addition, the fifth and sixth terminals B5 and B6 of the circuit board 190 may be coupled to the lower elastic units 160-1 and 160-2, and the first position sensor 170 may be electrically connected to the first coil 120 through the lower elastic units 160-1 and 160-2.

[0283] For example, the fifth terminal B5 of the circuit board 190 may be coupled to the first lower elastic unit 160-1, and the sixth terminal B6 of the circuit board 190 may be coupled to the second lower elastic unit 160-2.

[0284] Next, the upper elastic member 150, the lower elastic member 160, and the support member 220 will be described.

[0285] 8 shows the upper elastic member 150 shown in FIG. 1, FIG. 9 shows the lower elastic member 160 shown in FIG. 1, FIG. 10 shows a perspective view of the upper elastic member 150, the lower elastic member 160, the base 210, the support member 220, the second coil 230, and the circuit board 250, FIG. 11 shows the connection between the first to fourth terminals B1 to B4 of the circuit board 190 and the upper elastic units 150-1 to 150-4, and FIG. 12 shows the connection between the fifth and sixth terminals B1 to B4 of the circuit board 190 and the upper elastic units 150-1 to 150-4. 13 shows an exploded perspective view of the second coil 230, the circuit board 250, the base 210, and the second position sensor 240, FIG. 14 is a bottom view of the second coil 230 and the circuit board 190, FIG. 15 is a bottom view of the circuit board combined with the second coil 230, and FIG. 16 is a bottom view of the second coil 230, the circuit board 250, the solder 39A, and the adhesive members 290-1 to 290-4.

[0286] 8 to 16, the upper elastic member 150 may be coupled to the upper portion, upper end, or upper surface of the bobbin 110, and the lower elastic member 160 may be coupled to the lower portion, lower end, or lower surface of the bobbin 110.

[0287] For example, the upper elastic member 150 may be coupled to the upper portion, upper end, or upper surface of the bobbin 110 and the upper portion, upper end, or upper surface of the housing 140, and the lower elastic member 160 may be coupled to the lower portion, lower end, or lower surface of the bobbin 110 and the lower portion, lower end, or lower surface of the housing 140.

[0288] The upper elastic member 150 and the lower elastic member 160 can elastically support the bobbin 110 with respect to the housing 140 .

[0289] The support member 220 can support the housing 140 movably in a direction perpendicular to the optical axis relative to the base 210 , and can electrically connect at least one of the upper and lower elastic members 150 and 160 to the circuit board 250 .

[0290] 8, the upper elastic member 150 may include a plurality of upper elastic units 150-1 to 150-4 that are electrically isolated from one another. Although four electrically isolated upper elastic units are illustrated in FIG. 10, the number of the upper elastic units is not limited thereto and may be three or more.

[0291] Each of the first to fourth upper elastic units 150-1 to 150-4 may be directly coupled to a corresponding one of the first to fourth terminals B1 to B4 of the circuit board 190 to be electrically connected thereto.

[0292] A portion of each of the multiple upper elastic units may be arranged on the first side 141-1 of the housing 140 on which the circuit board 190 is arranged, and at least one upper elastic unit may be arranged on each of the remaining second to fourth sides 141-2 to 141-4 of the housing 140 excluding the first side 141-1.

[0293] Each of the first to fourth upper elastic units 150 - 1 to 150 - 4 may include a first outer frame 152 coupled to the housing 140 .

[0294] At least one of the first to fourth upper elastic units 150-1 to 150-4 may further include a first inner frame 151 coupled to the bobbin 110, and a first frame connection part 153 connecting the first inner frame 151 and the first outer frame 152.

[0295] In the embodiment of FIG. 8, each of the first and second upper elastic units 150-1, 150-2 may include only a first outer frame and not a first inner frame and not a first frame connection portion, and each of the first and second upper elastic units 150-1, 150-2 may be separated from the bobbin 110.

[0296] Each of the third and fourth upper elastic units 150-3 and 150-4 may include, but is not limited to, a first inner frame 151, a first outer frame, and a first frame connecting portion 153.

[0297] For example, but not limited to, the first inner frame 151 of the third and fourth upper elastic units 150-3 and 150-4 is provided with a hole 151a for coupling with the first coupling portion 113 of the bobbin 110. For example, the hole 152a of the first inner frame 151 may have at least one cutout 51a for an adhesive material to penetrate between the first coupling portion 113 of the bobbin 110 and the hole 151a.

[0298] The first outer frames 152 of the first to fourth upper elastic members 150-1 to 150-4 may have holes 152a for being coupled to the first coupling portion 143 of the housing 140. As shown in FIG.

[0299] The first outer frame 151 of each of the first to fourth upper elastic units 150-1 to 150-4 may include a main body portion coupled to the housing 140, and connecting terminals P1 to P4 coupled to corresponding ones of the first to fourth terminals B1 to B4 of the circuit board 190. Here, the connecting terminals P1 to P4 may be alternatively expressed as "extensions." For example, the support member 220 may be coupled to the main body portion of the first outer frame 151.

[0300] The first outer frame 151 of each of the first to fourth upper elastic units 150-1 to 150-4 may include a first connecting portion 520 connected to the housing 140, a second connecting portion 510 connected to a corresponding one of the support members 220-1 to 220-4, a connecting portion 530 connecting the first connecting portion 520 and the second connecting portion 510, and extension portions P1 to P4 connected to the second connecting portion 510 and extending to the first side portion 141-1 of the housing 140.

[0301] Each of the main body portions of the first to fourth upper elastic units 150-1 to 150-4 may include a first coupling portion 520. In addition, each of the main body portions of the first to fourth upper elastic units 150-1 to 150-4 may further include at least one of a second coupling portion 510 and a connecting portion 530.

[0302] For example, one end of the first support member 220-1 may be connected to the second connecting portion 510 of the first upper elastic unit 150-1, one end of the second support member 220-2 may be connected to the second connecting portion 510 of the second upper elastic unit 150-1, one end of the third support member 220-3 may be connected to the second connecting portion 510 of the third upper elastic unit 150-3, and one end of the fourth support member 220-4 may be connected to the second connecting portion 510 of the fourth upper elastic unit 150-4 by solder or a conductive adhesive member.

[0303] The second coupling part 510 may have holes 52 through which the support members 220-1 to 220-4 pass. One ends of the members 220-1 to 220-4 passing through the holes 52 may be directly coupled to the second coupling part 510 by a conductive adhesive member or solder (901, see FIG. 10), and the second coupling part 510 and the support members 220-1 to 220-4 may be electrically connected.

[0304] For example, the second coupling portion 510 is a region where the solder 901 is disposed for coupling with the support members 220-1 to 220-4, and may include the hole 52 and a region around the hole 52.

[0305] The first coupling portion 520 may include at least one coupling region (eg, 5a, 5b) coupled to the housing 140 (eg, corner portions 142-1 to 142-4).

[0306] For example, the coupling region (eg, 5 a , 5 b ) of the first coupling portion 520 may include at least one hole 152 a coupled to the first coupling portion 143 of the housing 140 .

[0307] For example, each of the coupling regions 5a and 5b may have one or more holes, and the corners 142-1 to 142-4 of the housing 140 may be provided with one or more first coupling portions corresponding thereto.

[0308] For example, in order to support the housing 140 in a balanced manner without leaning to either side, the connection regions 5a, 5b of the first connection portion 520 of the first to fourth upper elastic units 150-1 to 150-4 may be symmetrical with respect to a reference line (e.g., 501, 502), but is not limited to this.

[0309] In addition, the first coupling parts 143 of the housing 140 may be symmetrical with respect to a reference line (eg, 501, 502), and two are provided on each side of the reference line, but the number is not limited thereto.

[0310] The reference lines 501 and 502 may be straight lines passing through the center point 101 and any of the corners of the corner portions 142-1 to 142-4 of the housing 140. For example, the reference lines 501 and 502 may be straight lines passing through the center point 101 and two corners of the corner portions 142-1 to 142-4 of the housing 140 that face each other in the diagonal direction of the housing 140.

[0311] Here, the center point 101 may be the center of the housing 140, the center of the bobbin 110, or the center of the upper elastic member 150. The center point 101 may be the spatial center of said structure 140, 110, or 150.

[0312] Also for example, the corners of the housing 140 may be aligned or correspond to the centers of the corners of the housing 140 .

[0313] In the embodiment of FIG. 8, each of the coupling regions 5a, 5b of the first coupling portion 520 is implemented to include a hole 152a, but is not limited thereto, and in other embodiments, the coupling regions may be implemented in various shapes sufficient to couple with the housing 140, such as, for example, a groove shape.

[0314] For example, the hole 152a of the first coupling portion 520 may have at least one cutout 52a through which an adhesive material can be seeped between the first coupling portion 143 of the housing 140 and the hole 152a.

[0315] The connecting part 530 may connect the second connecting part 510 and the first connecting part 520 to each other.

[0316] For example, the connecting portion 530 may connect the connecting regions 5 a, 5 b of the second connecting portion 510 and the first connecting portion 520 .

[0317] For example, the connecting portion 530 may include a first connecting portion 530a connecting the first connecting region 5a of the first connecting portion 520 of each of the first to fourth upper elastic units 150-1 to 150-4 to the second connecting portion 510, and a second connecting portion 530b connecting the second connecting region 5b of the first connecting portion 520 to the second connecting portion 510.

[0318] For example, the first outer frame 151 may include, but is not limited to, a connecting region 5c that directly connects the first connecting region 5a and the second connecting region 5b.

[0319] Each of the first and second connecting portions 530a, 530b may include a bent portion that is bent at least once or a curved portion that is bent at least once, but is not limited thereto, and may be a straight line in other embodiments.

[0320] The width of the connecting portion 530 may be smaller than the width of the first connecting portion 520. Also, the width of the connecting portion 530 may be smaller than the width (or diameter) of the first connecting portion. In other embodiments, the width of the connecting portion 530 may be the same as the width of the first connecting portion 520, or may be the same as the width (or diameter) of the first connecting portion.

[0321] For example, first coupling part 520 may come into contact with upper surfaces of corner parts 142-1 to 142-4 of housing 140 and may be supported by corner parts 142-1 to 142-4 of housing 140. For example, connecting part 530 may not be supported by the upper surface of housing 140 and may be spaced apart from housing 140. Also, a damper (not shown) may be filled in a space between connecting part 530 and housing 140 to prevent oscillation due to vibration.

[0322] The width of each of the first and second connecting parts 530a, 530b may be narrower than the width of the first joining part 520, thereby making it easier for the connecting part 530 to move in the first direction and thereby dispersing the stress applied to the upper elastic units 150-1 to 150-4 and the stress applied to the support members 220-1 to 220-4.

[0323] Each of the first and second extension portions P1, P2 of the first outer frames of the first and second upper elastic units 150-1, 150-2 may extend from the first coupling portion 520 (e.g., the first coupling area 5a) toward a corresponding one of the first and second terminals B1, B2 of the circuit board 190 located on the first side 141-1 of the housing 140.

[0324] The first coupling portion 520 of the third upper elastic unit 150-3 may further include at least one coupling region 6a, 6b coupled to at least one of the fourth side portion 141-4 and the second corner portion 142-2 of the housing 140.

[0325] In addition, the first coupling portion 520 of the fourth upper elastic unit 150-4 may further include at least one coupling region 6c, 6d coupled to at least one of the third side portion 141-3 and the first corner portion 142-1 of the housing 140.

[0326] Each of the third and fourth extension portions P3, P4 of the first outer frames of the third and fourth upper elastic units 150-3, 150-4 may extend from the first coupling portion 520 (e.g., coupling areas 6b, 6d) toward a corresponding one of the third and fourth terminals B3, B4 of the circuit board 190 located on the first side 141-1 of the housing 140.

[0327] One end of each of the first to fourth extension portions P1 to P4 may be coupled to a corresponding one of the first to fourth terminals B1 to B4 of the circuit board 190 by soldering or a conductive adhesive member.

[0328] Each of the first and second extensions P1 and P2 may have a straight line shape, but is not limited thereto, and may include a bent or curved portion in other embodiments.

[0329] To facilitate coupling with a corresponding one of the third and fourth terminals B3, B4 of the circuit board 190, the third and fourth extensions P3, P4 may include bent or curved portions.

[0330] The first outer frame of the third upper elastic unit 150-3 may further include a first extension frame 154-1 connected between the first connecting portion 520 and the extension portion P3 and positioned at the fourth side portion 141-4 and the second corner portion 142-2 of the housing 140.

[0331] In order to strengthen the bonding force with the housing 140 and prevent the third upper elastic unit 150-3 from floating, the first extension frame 154-1 may include at least one bonding area 6a, 6b to be bonded to the housing 140, and the bonding area 6a, 6b may have a hole for bonding to the first bonding portion 143 of the housing 140.

[0332] The first outer frame of the fourth upper elastic unit 150-4 may further include a second extension frame 154-2 connected between the first connecting portion 520 and the extension portion P4 and positioned at the third side portion 141-3 and the first corner portion 142-1 of the housing 140.

[0333] In order to strengthen the bonding force with the housing 140 and prevent the fourth upper elastic unit 150-4 from floating, the second extension frame 154-2 may include at least one bonding area 6c, 6d to be bonded to the housing 140, and the bonding area 6c, 6d may have a hole for bonding to the first bonding portion 143 of the housing 140.

[0334] In FIG. 8, each of the third upper elastic unit 150-3 and the fourth upper elastic unit 150-4 includes two first frame connecting parts, but is not limited thereto, and the number of the first frame connecting parts may be one or three or more.

[0335] As described above, each of the first to fourth upper elastic units may include extension portions P1 to P4 arranged on the first side portion 141-1 of the housing 140, and the upper elastic units 150-1 to 150-4 may be easily coupled to the first to fourth terminals B1 to B4 provided on the main body portion S1 of the circuit board 190 via the extension portions P1 to P4.

[0336] Since the four terminals B1 to B4 provided on the main body portion S1 of the circuit board 190 arranged on the first side portion 141-1 of the housing 140 are directly electrically connected to the first to fourth upper elastic units 150-1 to 150-4, a portion of the first outer frame 151 of each of the first to fourth upper elastic units 150-1 to 150-4 can be arranged on the first side portion 141-1 of the housing 140.

[0337] Each of the upper elastic units 150-1 to 150-4 may be disposed or coupled to a corresponding one of the corner portions 142-1 to 142-4 of the housing 140, and may include extension portions P1 to P4 extending to the first side portion 141-1 of the housing 140.

[0338] Referring to FIG. 11, each of the extension portions P1 to P4 of the upper elastic units 150-1 to 150-4 can be directly coupled to a corresponding one of the four terminals B1 to B4 provided on the main body portion S1 of the circuit board 190 by a conductive adhesive member 71 such as solder.

[0340] A portion of the third upper elastic unit 150-3 may be disposed in the first groove 90a of the first circuit board 190, and an end of the portion of the third upper elastic unit 150-3 may be coupled to the third terminal B3 of the circuit board 190.

[0341] A portion of the fourth upper elastic unit 150-4 may be disposed in the second groove 90b of the first circuit board 190, and an end of the portion of the fourth upper elastic unit 150-4 may be coupled to the fourth terminal B4 of the circuit board 190.

[0342] The third extension portion P3 of the third upper elastic unit 150-3 can pass through the first groove 90a of the circuit board 190 and extend toward the third terminal B3 of the circuit board 190, and be bent at least twice.

[0343] In addition, the fourth extension portion P4 of the fourth upper elastic unit 150-4 may pass through the second groove 90b of the circuit board 190 and extend toward the fourth terminal B4 of the circuit board 190, and be bent at least twice.

[0344] The third extension portion P3 (or the "third connecting terminal") of the third upper elastic unit 150-3 may include at least two bending regions 2a, 2b.

[0345] For example, the third extension portion P3 of the third upper elastic unit 150-3 may include a first portion 1a extending from the first connecting portion 520 (e.g., connecting region 6b) of the third upper elastic unit 150-3, a first bending region 2a (or a "first bending portion") folded at the first portion 1a, a second portion 1b extending at the first bending region 2a, a second bending region 2b (or a "second bending portion") folded at the second portion 1b, and a third portion 1c extending in the direction of the third terminal B3 at the second bending region 2b.

[0346] For example, the second portion 1b of the third extension portion P3 (or the third connecting terminal) is bent from the first portion 1a, and the third portion 1c is bent from the second portion 1b.

[0347] The second portion 1b of the third extension portion P3 may be disposed between the first folding region 2a and the second folding region 2b to connect the first and second folding regions 2a, 2b.

[0348] For example, each of the first portion 1a and the third portion 1c of the third extension portion P3 may extend in a direction from the second corner portion 142-2 of the housing 140 toward the first corner portion 141-1. For example, the second portion 1b of the third extension portion P3 may extend from the inner surface of the housing 140 toward the outer surface of the housing 140.

[0349] A part of the third extension portion P3 of the third upper elastic unit 150-3 (eg, the second portion 1b) can be positioned within the first groove 90a of the circuit board 190 or pass through the first groove 90a.

[0350] The fourth extension portion P4 (or the "fourth connecting terminal") of the fourth upper elastic unit 150-4 may include at least two bending regions 2c and 2d.

[0351] For example, the fourth extension portion P4 of the fourth upper elastic unit 150-4 may include a fourth portion 1d extending from the first connecting portion 520 (e.g., connecting region 6d) of the fourth upper elastic unit 150-4, a third bending region 2c (or a "third bending portion") folded at the fourth portion 1d, a fifth portion 1e extending from the third bending region 2c, a fourth bending region 2d (or a "fourth bending portion") folded at the fifth portion 1e, and a sixth portion 1f extending from the fourth bending region 2d in the direction of the fourth terminal B4.

[0352] For example, the fifth portion 1e of the fourth extension portion P4 (or the fourth connecting terminal) is bent at the fourth portion 1d, and the sixth portion 1f is bent at the fifth portion 1e.

[0353] The fifth portion 1e of the fourth extension portion P4 may be disposed between the third folding region 2c and the fourth folding region 2d to connect the third and fourth folding regions 2c, 2d.

[0354] For example, each of the fourth portion 1d and the sixth portion 1f of the fourth extension portion P4 may extend in a direction from the first corner portion 142-1 toward the second corner portion 141-2 of the housing 140. For example, the fifth portion 1e of the fourth extension portion P4 may extend from the inner surface of the housing 140 toward the outer surface thereof.

[0355] A part of the fourth extension portion P4 of the fourth upper elastic unit 150-4 (eg, the fifth portion 1e) can be positioned within the second groove 90b of the circuit board 190 or pass through the second groove 90b.

[0356] Referring to FIG. 9, the lower elastic member 160 may include a plurality of lower elastic units 160-1, 160-2.

[0357] For example, each of the first and second lower elastic units 160-1, 160-2 may include a second inner frame 161 coupled or fixed to the lower part, lower surface, or lower end of the bobbin 110, second outer frames 162-1 to 162-3 coupled or fixed to the lower part, lower surface, or lower end of the housing 140, and a second frame connection portion 163 connecting the second inner frame 161 and the second outer frames 162-1 to 162-3 to each other.

[0358] The second inner frame 161 may be provided with a hole 161a for coupling to the second coupling portion 117 of the bobbin 110, and the second outer frames 162-1 to 162-3 may be provided with a hole 162a for coupling to the second coupling portion 149 of the housing 140.

[0359] For example, but not limited to, each of the first and second lower elastic units 160-1 and 160-2 may include three second outer frames 162-1 to 162-3 and two second frame connecting parts 163 coupled to the housing 140. In other embodiments, each of the first and second lower elastic units may include one or more second outer frames and one or more second frame connecting parts.

[0360] Each of the first and second lower elastic units 160-1 and 160-2 may include connection frames 164-1 and 164-2 that connect the second outer frames 162-1 to 162-3 to each other.

[0361] The width of each of the connecting frames 164-1, 164-2 may be smaller than the width of each of the second outer frames 162-1 to 162-3, but is not limited to this.

[0362] The connection frames 164-1 and 164-2 may be located outside the coil units 230-1 to 230-4 and the magnets 130-1 to 130-4 based on the coil units 230-1 to 230-4 and the magnets 130-1 to 130-4 to avoid spatial interference with the second coil 230 and the first magnet 130. In this case, the outside of the coil units 230-1 to 230-4 and the magnets 130-1 to 130-4 may be the opposite side of the region where the center of the bobbin 110 or the center of the housing 140 is located based on the coil units 230-1 to 230-4 and the magnets 130-1 to 130-4.

[0363] Also, for example, the connecting frames 164-1, 164-2 may be positioned so as not to overlap with the coil units 230-1 to 230-4 and / or magnets 130-1 to 130-4 in the optical axis direction, but this is not limited thereto, and in other embodiments, at least a portion of the connecting frames 164-1, 164-2 may be aligned with or overlap with the coil units 230-1 to 230-4 and / or magnets 130-1 to 130-4 in the optical axis direction.

[0364] The upper elastic units 150-1 to 150-4 and the lower elastic units 160-1 and 160-2 are made of leaf springs, but are not limited thereto and may be realized by coil springs, etc. The "elastic unit (e.g., 150 or 160)" expressed above may be expressed as a "spring", the "outer frame (e.g., 152 or 162)" may be expressed as an "outer part", the "inner frame (e.g., 151 or 161)" may be expressed as an "inner part", and the support member (e.g., 220) may be expressed as a wire.

[0365] Next, the support members 220-1 to 220-4 will be described. The support members 220-1 to 220-4 may be disposed at the corner portions 142-1 to 142-4 of the housing 140, and may connect the upper elastic units 150-1 to 150-4 and the circuit board 250 to each other.

[0366] Each of the support members 220-1 to 220-4 can be coupled to a corresponding one of the first to fourth upper elastic units 150-1 to 150-4, and can electrically connect a corresponding one of the first to fourth upper elastic units 150-1 to 150-4 to a corresponding one of the terminals (251-1 to 251-n, for example, n=4) of the circuit board 250.

[0367] The support members 220-1 to 220-4 may be spaced apart from the housing 140, and may not be fixed to the housing 140, but one end of the support members 220-1 to 220-4 may be directly connected or coupled to the second coupling portion 510 of the upper elastic units 150-1 to 150-4. In addition, the other end of the support members 220-1 to 220-4 may be directly connected or coupled to the circuit board 250.

[0368] For example, but not limited to, the support members 220-1 to 220-4 may pass through holes 147 provided in the corner portions 142-1 to 142-4 of the housing 140. In other embodiments, the support members may be disposed adjacent to the boundary lines between the side portions 141-1 to 141-4 and the corner portions 142-1 to 142-4 of the housing 140 and may not pass through the corner portions 142-1 to 142-4 of the housing 140.

[0369] The first coil 120 may be electrically connected to the first and second lower elastic units 160-1 and 160-2.

[0370] For example, the first coil 120 may be directly connected or coupled to a corresponding one of the second inner frames of the first and second lower elastic units 160-1 and 160-2. For example, the second inner frame 161 of the first lower elastic unit 160-1 may include a first bonding portion 43a coupled to one end of the first coil 120, and the second inner frame 161 of the second lower elastic unit 160-2 may include a second bonding portion 43b coupled to the other end of the first coil 120. Each of the first and second bonding portions 43a and 43b may be provided with a groove 8a for guiding the coil 120.

[0371] The first support member 220-1 may be disposed at a first corner portion 142-1 of the housing 140 and may be coupled to the second coupling portion 510 of the first upper elastic unit 150-1.

[0372] The second support member 220-2 may be disposed at the second corner portion 142-2 of the housing 140 and may be coupled to the second coupling portion 510 of the second upper elastic unit 150-2.

[0373] The third support member 220-3 may be disposed in a third corner portion 142-3 of the housing 140 and may be coupled to the second coupling portion 510 of the third upper elastic unit 150-3.

[0374] The fourth support member 220-4 may be disposed at a fourth corner portion 142-4 of the housing 140 and may be coupled to the second coupling portion 510 of the fourth upper elastic unit 150-4.

[0375] The first terminal B1 of the circuit board 190 may be electrically connected to the first support member 220-1, the second terminal B2 of the circuit board 190 may be electrically connected to the second support member 220-2, the third terminal B3 of the circuit board 190 may be electrically connected to the third support member 220-3, and the fourth terminal B4 of the circuit board 190 may be electrically connected to the fourth support member 220-4.

[0376] Each of the first to fourth support members 220-1 to 220-4 may be electrically connected to a corresponding one of the first to fourth terminals (eg, 251-1 to 251-n, n=4) of the circuit board 250.

[0377] For example, power signals (VDD, GND) may be provided to the first and second support members 220-1 and 220-2 through the first and second terminals 251-1 and 251-2 of the circuit board 250.

[0378] For example, power signals (VDD, GND) may be provided to the first and second terminals B1, B2 of the circuit board 190 via the first and second support members 220-1, 220-2 and the first and second upper elastic units 150-1, 150-2. The first position sensor 170 may receive the power signals (VDD, GND) via the first and second terminals B1, B2 of the circuit board 190.

[0379] For example, the first terminal B1 of the circuit board 190 may be either the VDD terminal or the GND terminal, and the second terminal B2 of the circuit board 190 may be the remaining one of the VDD terminal and the GND terminal.

[0380] In addition, a clock signal (SCL) and a data signal (SDA) can be provided to the third and fourth support members 220-3 and 220-4 via the third and fourth terminals 251-3 and 251-4 of the circuit board 250.

[0381] A clock signal (SCL) and a data signal (SDA) may be provided to the third and fourth terminals B3 and B4 of the circuit board 190 via the third and fourth support members 220-3 and 220-4 and the third and fourth upper elastic units 150-3 and 150-4. The first position sensor 170 may receive the clock signal (SCL) and the data signal (SDA) via the third and fourth terminals B3 and B4 of the circuit board 190.

[0382] For example, a power signal (VDD) may be provided to the first position sensor 170 via a first terminal 251-1 of the circuit board 250, the first support member 220-1, the first upper elastic unit 150-1, and a first terminal B1 of the circuit board 190. A power signal (GND) may be provided to the first position sensor 170 via a second terminal 251-2 of the circuit board 250, the second support member 220-2, the second upper elastic unit 150-2, and a second terminal B2 of the circuit board 190.

[0383] For example, a clock signal (SCL) may be provided to the first position sensor 170 via the third terminal 251-3 of the circuit board 250, the third support member 220-3, the third upper elastic unit 150-3, and the third terminal B3 of the circuit board 190. A data signal (SDA) may be provided to the first position sensor 170 via the fourth terminal 251-4 of the circuit board 250, the fourth support member 220-4, the fourth upper elastic unit 150-4, and the fourth terminal B4 of the circuit board 190.

[0384] Each of the fifth and sixth terminals B5 and B6 of the circuit board 190 is connected or coupled to a corresponding one of the second outer frames 162-1 of the first and second lower elastic units 160-1 and 160-2.

[0385] The second outer frame 162-1 of the first lower elastic unit 160-1 may include a first bonding portion 81a to which the fifth terminal B5 of the circuit board 190 is coupled by soldering or a conductive adhesive member. Also, the second outer frame 162-1 of the second lower elastic unit 160-2 may include a second bonding portion 81b to which the sixth terminal B5 of the circuit board 190 is coupled by soldering or a conductive adhesive member.

[0386] For example, the second outer frame 162-1 of the first lower elastic unit 160-1 may have a first hole 82a (or a first groove) into which the fifth terminal B5 of the circuit board 190 is inserted or positioned, and the second outer frame 162-1 of the second lower elastic unit 160-2 may have a second hole 82b (or a second groove) into which the sixth terminal B6 of the circuit board 190 is inserted or positioned.

[0387] For example, each of the first and second holes 82a, 82b may penetrate the second outer frame 161-1 and have an opening that is open to one side of the second outer frame 161-1, but is not limited to this, and in other embodiments, it may not have an opening that is open to one side of the second outer frame 161-1.

[0388] When the fifth terminal B5 (or the sixth terminal B6) of the circuit board 190 is inserted into the first groove 82a (or the second groove 82b) of the second outer frame 162-1 of the first lower elastic unit 160-1, the fifth terminal B5 (or the sixth terminal B6) is bonded to the first bonding portion 81a (or the second bonding portion 81b) provided with the first groove 82a (or the second groove 82b) by soldering or a conductive adhesive member, thereby increasing the bonding area and improving the bonding strength and solderability between the two.

[0389] 12, one end (e.g., lower end or lower surface) of each of the fifth and sixth terminals B5, B6 may be located lower than the lower end or lower surface of the second outer frame 162-1 of the first and second lower elastic units 160-1, 160-2. Since FIG. 12 is a bottom view, it may be expressed that the lower surface of each of the fifth and sixth terminals B5, B6 is located lower than the lower end or lower surface of the second outer frame 162-1. This is to improve solderability between one end of each of the fifth and sixth terminals B5, B6 and the first and second bonding parts 81a, 81b of the first and second lower elastic units 160-1, 160-2.

[0390] 12, the housing 140 may include a groove 31 recessed from a lower surface of the first side portion 141-1. For example, a bottom surface of the groove 31 of the housing 140 may have a step with the lower surface of the housing 140 in the optical axis direction. For example, the bottom surface of the groove 31 of the housing 140 may be positioned higher than the lower surface of the housing 140.

[0391] The groove 31 of the housing 140 may overlap the first and second bonding portions 81a and 81b of the first and second lower elastic units 160-1 and 160-2 in the optical axis direction.

[0392] In addition, the groove 31 of the housing 140 overlaps with the holes 82a, 82b of the second outer frame 162-1 of the first and second lower elastic units 160-1, 160-2 in the optical axis direction, but is not limited to this and in other embodiments, the two may not overlap.

[0393] The groove 31 of the housing 140 can increase the area over which the fifth and sixth terminals B5, B6 of the circuit board 190 are exposed from the housing 140, thereby providing space for soldering or conductive adhesive members to be seated, thereby improving solderability, and reducing the degree to which the solder protrudes below the underside of the second outer frame 162-1, thereby suppressing or preventing spatial interference with the second coil 230, the circuit board 250, or the base 210 arranged below the lower elastic unit.

[0394] In addition, the lower surface 11c of the first magnet 130 arranged in the mounting portion 141a of the housing 140 may be located lower than the lower surfaces of the second outer frames 162-1 to 162-3 of the first and second lower elastic units 160-1 and 160-2, but is not limited to this. In other embodiments, the lower surface 11c of the first magnet 130 may be higher or the same height as the lower surfaces of the second outer frames 162-1 to 162-3 or the lower surface of the housing 140.

[0395] In order to space the first magnet 130 apart from the second coil 230 and the circuit board 250, the other end of the support member 220 may be coupled to the circuit board 250 (or the circuit member 231) at a position lower than the lower surface 11c of the first magnet 130.

[0396] The support member 220 may be realized by a conductive and elastically supported member, for example, a suspension wire, a leaf spring, a coil spring, etc. In another embodiment, the support member 220 may be integrally formed with the upper elastic member 150.

[0397] Next, the base 210, the circuit board 250, the second coil 230, and the adhesive member 290 will be described.

[0398] 13, the base 210 may have an opening (C3) corresponding to the opening of the bobbin 110 or / and the opening of the housing 140, and may have a shape, for example, a rectangular shape, that matches or corresponds to the cover member 300. For example, the opening (C3) of the base 210 may be in the form of a through-hole that penetrates the base 210 in the optical axis direction.

[0399] The base 210 may include a locking portion 211 to which an adhesive may be applied when adhesively fixing the cover member 300. At this time, the locking portion 211 may guide the side plate 302 of the cover member 300 to be coupled to the upper side, and a lower end of the side plate 302 of the cover member 300 may come into contact with the locking portion 211. The locking portion 211 of the base 210 and the lower end of the side plate 302 of the cover member 300 may be adhered and fixed by an adhesive or the like.

[0400] A support portion 255 may be provided in a region of the base 210 facing the terminal surface 253 on which the terminals 251-1 to 251-n of the circuit board 250 are provided. The support portion 255 may support the terminal surface 253 of the circuit board 250 on which the terminals 251-1 to 251-n of the circuit board 250 are formed. For example, the support portion 255 may be in the form of a groove recessed from the outer surface of the base 210, but is not limited thereto, and in other embodiments, the support portion 255 may be in the same plane as the outer surface of the base 210 or in a protruding form.

[0401] A protrusion 48 or projection extending or protruding toward an outer surface of the base 210 may be formed on a side of the circuit board 250, and a groove 28 or coupling groove having a shape corresponding to a position corresponding to the protrusion 48 of the circuit board 250 may be formed on the outer surface of the base 210. The protrusion 48 of the circuit board 250 may be disposed, coupled, or seated in the groove 28 of the base 210.

[0402] The base 210 may include escape portions 212-1 to 212-4 for avoiding spatial interference with the support member 220.

[0403] For example, the base 210 may have escape portions 212-1 to 212-4 in corner regions corresponding to the corners of the cover member 300. The escape portions 212-1 to 212-4 may be in the form of grooves, holes, or the like for avoiding spatial interference with the support members 220-1 to 220-4 and the adhesive member (or solder 902).

[0404] For example, the escape portions 212-1 to 212-4 of the base 210 may be recessed from the outer surfaces of the corners of the base 210 toward the center of the base 210. The escape portions 212-1 to 212-4 of the base 210 may be open to the upper and lower surfaces of the base 210.

[0405] For example, the recesses 212-1 to 212-4 of the base 210 may expose a partial area (e.g., a first area or a corner area) of the lower surface of the circuit board 250. In other embodiments, the recesses of the base 210 may expose a partial area (e.g., a first area or a corner area) of the lower surface of the circuit member 231.

[0406] The adhesive member 290 can connect the inner surfaces of the corners of the cover member 300 and the recesses 212-1 to 212-4 of the base 210 to each other.

[0407] For example, the adhesive member 290 may be disposed on a portion of the lower surface of the circuit board 250 (eg, a first region or a corner region).

[0408] For example, the adhesive member 290 may be disposed on at least one of the escape portions 212-1 to 212-4, a partial region (e.g., a first region or a corner region) of the lower surface of the circuit board 250, and a partial region of the lower surface of the base 210 adjacent to the escape portions 212-1 to 212-4. For example, the partial region of the lower surface of the base 210 may include the stepped portion 320. In still another embodiment, for example, the partial region of the lower surface of the base 210 may include the stepped portion 320 and a region of the lower surface of the base 210 adjacent to the stepped portion 320.

[0409] In addition, the upper surface of the base 210 may be provided with seating grooves 215-1 and 215-2 in which the second position sensor 240 may be disposed.

[0410] For example, the first mounting groove 215-1 of the base 210 may be formed adjacent to any one of the escape portions 212-3 provided at any one of the corners of the base 210, and the second mounting groove 215-2 of the base 210 may be formed adjacent to another one of the escape portions 212-4 provided at another one of the corners of the base 210.

[0411] For example, the first mounting groove 215-1 of the base 210 may be formed on the upper surface of the base 210 located between any one of the escape portions 212-3 and the protrusion 19, and the second mounting groove 215-2 may be formed on the upper surface of the base 210 located between any other one of the escape portions 212-4 and the protrusion 19.

[0412] For example, a seat (not shown) on which the filter 610 of the camera module 200 is installed may be formed on the lower surface of the base 210 .

[0413] In addition, a protrusion 19 for coupling with the opening (C2) of the circuit board 250 and the opening (C1) of the circuit member 231 may be provided on the upper surface around the opening (C3) of the base 210.

[0414] The protrusion 19 of the base 210 may have the same shape as the opening (C3), for example, a circular shape, but is not limited thereto. For example, the protrusion 19 may have a single circular shape, but is not limited thereto, and may include multiple portions spaced apart from each other.

[0415] The base 210 may have a protrusion 32 protruding from an upper surface thereof to be coupled to a coupling groove 33 of the circuit board 250 .

[0416] For example, the coupling groove 33 of the circuit board 250 may be formed on an inner surface of the circuit board 250 formed by the opening (C2) and may be recessed from the inner surface of the circuit board 250. Also, the protrusion 32 of the base 210 may correspond to or face the coupling groove 33 of the circuit board 250 in the optical axis direction, and the protrusion 32 may have a shape corresponding to or matching with the coupling groove 33 of the circuit board 250. For example, the protrusion 32 may contact an outer surface of the protruding portion 19 of the base 210.

[0417] The second coil 230 may be disposed on the upper portion of the circuit board 250 , and the OIS position sensors 240 a and 240 b may be disposed in the seating grooves 215 - 1 and 215 - 2 of the base 210 located below the circuit board 250 .

[0418] The second position sensor 240 may include first and second OIS position sensors 240a and 240b, and the OIS position sensors 240a and 240b may detect the displacement of the OIS movable part in a direction perpendicular to the optical axis. Here, the OIS movable part may include an AF movable part and components attached to the housing 140.

[0419] For example, the OIS moving part may include an AF moving part and a housing 140, and may further include a first magnet 130 depending on the embodiment.

[0420] The circuit board 250 is disposed on the upper surface of the base 210 and may include an opening (C2) corresponding to the opening of the bobbin 110, the opening of the housing 140, and / or the opening (C3) of the base 210. The opening (C2) of the circuit board 250 may be in the form of a through hole.

[0421] The shape of the circuit board 250 may be a shape that matches or corresponds to the top surface of the base 210, for example, a rectangular shape.

[0422] The circuit board 250 may be bent from the top surface to have at least one terminal surface 253 on which a plurality of terminals (251-1 to 251-n, n is a natural number greater than 1) or pins are provided to receive electrical signals from the outside.

[0423] For example, referring to FIG. 14, a circuit board 250 may include, but is not limited to, two terminal surfaces 253-1, 253-2 facing or opposite each other, and the number of terminal surfaces 253 may be one or more.

[0424] The second coil 230 may be disposed below the bobbin 110. For example, the second coil 230 may be disposed below the housing 140.

[0425] The second coil 230 is disposed on the upper part of the circuit board 250 in correspondence with or facing the magnets 130-1 to 130-4 disposed in the housing 140.

[0426] The second coil 230 may include coil units 230-1 to 230-4 that face the magnets 130-1 to 130-4 arranged in the corner portions 142-1 to 142-4 of the housing 140 in the optical axis direction or that overlap with the magnets 130-1 to 130-4 in the optical axis direction.

[0427] For example, the second coil 230 may include a circuit member 231 and a plurality of coil units 230-1 to 230-4 formed on the circuit member 231. Here, the circuit member 231 may be expressed as a "substrate," a "circuit board," a "coil board," or the like. In other embodiments, the second coil 230 may omit the circuit member 231 and include the coil units 230-1 to 230-4.

[0428] The shape of the circuit member 231 may be a shape that matches or corresponds to the top surface of the base 210 or the circuit board 250, for example, a rectangular shape.

[0429] For example, the four coil units 230-1 to 230-4 may be disposed or formed at corners or corner regions of a polygonal (e.g., rectangular) circuit member 231. Each of the coil units 230-1 to 230-4 may have a shape corresponding to or matching the shape of the magnets 130-1 to 130-4 corresponding to the optical axis direction.

[0430] For example, each of the coil units 230-1 to 230-4 may have a closed curve shape, such as a ring shape, rotating around the optical axis when viewed from above.

[0431] Each of the coil units 230-1 to 230-4 may be in the form of a coil block formed of a fine pattern (FP) coil, but is not limited thereto.

[0432] In an embodiment in which the magnet is disposed on the side of the housing 140, the coil unit of the second coil can be arranged parallel to a side of the circuit member 231 and can have a shape that corresponds to or matches the shape of the magnet disposed on the side of the housing.

[0433] For example, the second coil 230 may include, but is not limited to, two coil units 230-1, 230-3 for the second direction and two coil units 230-2, 230-4 for the third direction.

[0434] For example, coil units 230-1 and 230-3 may be disposed in two corner regions of circuit member 231 facing each other in a first diagonal direction of circuit member 231, and coil units 230-2 and 230-4 may be disposed in two other corner regions of circuit member 231 facing each other in a second diagonal direction of circuit member 231.

[0435] The first diagonal direction and the second diagonal direction may be directions perpendicular to each other. For example, the first diagonal direction may be the X-axis direction, and the second diagonal direction may be the Y-axis direction.

[0436] The coil units 230-1 and 230-3 for the second direction may have electromagnetic forces acting in the same direction due to interaction with the magnets 130-1 and 130-3 corresponding to the optical axis direction, and the coil units 230-2 and 230-4 for the third direction may have electromagnetic forces acting in the same direction due to interaction with the magnets 130-2 and 130-4 corresponding to the optical axis direction.

[0437] In other embodiments, the second coil 230 may include only one coil unit for the second direction and one coil unit for the third direction, or may include four or more coil units.

[0438] The second coil 230 may be electrically connected to the circuit board 250. For example, the second coil 230 may be electrically connected to a terminal 251 of the circuit board 250.

[0439] The second coil 230 may be provided with a power source or a drive signal from the circuit board 250. The power source or drive signal provided to the second coil 230 may be a DC signal or an AC signal, or may include a DC signal and an AC signal, and may be in the form of a current or a voltage.

[0440] Interaction between the magnets 130-1 to 130-4 and the second coils 230-1 to 230-4 to which driving signals are provided may cause the housing 140 to move in a second and / or third direction, e.g., the X-axis and / or Y-axis directions, thereby enabling image stabilization.

[0441] 14 to 16, the second coil 230 may include terminals 30A to 30D for receiving drive signals from the circuit board 250. As shown in FIG.

[0442] For example, the circuit member 231 may include four terminals 30A to 30D. For example, the four terminals 30A to 30D may be disposed or provided on the lower surface of the circuit member 231.

[0443] For example, the four terminals 30A-30D may be formed adjacent to at least one side of the circuit member 231. For example, the two terminals 30B, 30D of the circuit member 231 may be disposed on the lower surface of the circuit member 231 adjacent to a first side of the circuit member 231 and may be located between the third coil unit 230-1 and the fourth coil unit 230-4.

[0444] The remaining two terminals 30A, 30C of the circuit member 231 may be disposed on the lower surface of the circuit member 231 adjacent to the second side surface of the circuit member 231 and may be located between the first coil unit 230-2 and the second coil unit 230-2. For example, the first side surface and the second side surface of the circuit member 231 may be located opposite to each other.

[0445] The first coil unit 230-1 and the third coil unit 230-3 may be connected in series to each other, and the second coil unit 230-2 and the fourth coil unit 230-4 may be connected in series to each other.

[0446] For example, one end of the first coil unit 230-1 may be electrically connected to the first terminal 30A of the circuit member 231, one end of the third coil unit 230-1 may be electrically connected to the second terminal 30B of the circuit member 231, and the other end of the first coil unit 230-1 and the other end of the third coil unit 230-3 may be electrically connected to each other. For example, the other end of the first coil unit 230-1 and the other end of the third coil unit 230-3 may be electrically connected to each other via a first conductive pattern or a first wiring formed in the circuit member 231.

[0447] For example, one end of the second coil unit 230-1 may be electrically connected to the third terminal 30C of the circuit member 231, one end of the fourth coil unit 230-4 may be electrically connected to the fourth terminal 30D of the circuit member 231, and the other end of the third coil unit 230-3 and the other end of the fourth coil unit 230-4 may be electrically connected to each other. For example, the other end of the third coil unit 230-3 and the other end of the fourth coil unit 230-4 may be electrically connected to each other via a second conductive pattern or a second wiring formed in the circuit member 231.

[0448] The circuit board 250 may include pads 27a to 27d for electrically connecting to the coil units 230-1 to 230-4. Here, the pads 27a to 27d may be alternatively expressed as "terminals" or "bonding parts".

[0449] The circuit board 250 may include pads 27a to 27d that correspond to or face the first to fourth terminals 30A to 30D of the circuit member 231 in the optical axis direction.

[0450] For example, the pads 27a-27d of the circuit board 250 may be disposed or provided on the lower surface of the circuit board 250. Each of the pads 27a-27d of the circuit board 250 may have a groove that exposes a portion of a corresponding one of the terminals 30A-30D of the circuit member 231. Each of the pads 27a-27d of the circuit board 250 and the corresponding terminals 30A-30D of the circuit member 231 may be bonded to each other by a conductive adhesive member or solder 39A, and thus electrically connected to each other.

[0451] For example, the pads 27a to 27d of the circuit board 250 may be disposed or formed on the lower surface of the circuit board 250 adjacent to at least one side surface of the circuit board 250 on which the terminal surface 253 is not formed.

[0452] For example, the two coil units 230-1, 230-3 for the second direction may be connected in series with each other, one end of the series-connected coil units 230-1, 230-3 may be electrically connected to the first pad 27a of the circuit board 250, and the other end of the series-connected coil units 230-1, 230-3 may be electrically connected to the second pad 27b of the circuit board 250.

[0453] For example, the two coil units 230-2, 230-4 for the third direction may be connected in series with each other, one end of the series-connected coil units 230-2, 230-4 may be electrically connected to the third pad 27c of the circuit board 250, and the other end of the series-connected coil units 230-2, 230-4 may be electrically connected to the fourth pad 27d of the circuit board 250.

[0454] The first and second pads 27a, 27b of the circuit board 250 may be electrically connected to two corresponding terminals among the terminals 251-1 to 251-n of the circuit board 250, and a first driving signal may be provided to the coil units 230-1, 230-3 connected in series via the two corresponding terminals of the circuit board 250.

[0455] The third and fourth pads 27c, 27d of the circuit board 250 may be electrically connected to two other corresponding terminals among the terminals 251-1 to 251-n of the circuit board 250, and a second driving signal may be provided to the coil units 230-2, 230-4 connected in series via the other two corresponding terminals of the circuit board 250.

[0456] In FIG. 13, the coil units 230-1 to 230-4 are realized in the form of a circuit pattern formed on a circuit member 231 separate from the circuit board 250, for example, in the form of an FP coil, but are not limited thereto.

[0457] In another embodiment, the coil units 230-1 to 230-4 may be realized in the form of a ring-shaped coil block with the circuit member 231 omitted.

[0458] In still another embodiment, the coil units 230-1 to 230-4 may be realized in the form of a circuit pattern, for example, an FP coil, directly formed on the circuit board 250. In this case, the circuit board 250 may be alternatively expressed as a "circuit member", and the circuit member may include a substrate portion on which the coil units 230-1 to 230-4 are formed and a terminal portion on which the terminals are formed, and the description of the circuit board 250 may be applied or mutatis mutandis to the substrate portion, and the description of the terminal portions 253, 253-1, and 253-2 of the circuit board 250 may be applied or mutatis mutandis to the terminal portion.

[0459] As described above, at least one of the circuit member 231 and / or the circuit board 250 may have a hole or an escape groove formed therein to avoid spatial interference with the support member 220 .

[0460] The circuit member 231 may be provided with an escape groove 24 to avoid spatial interference with the fifth and sixth terminals B5 and B6 of the circuit board 190. For example, the escape groove 24 may be formed on any one side of the circuit member 231 to correspond to, face or overlap with the fifth and sixth terminals B5 and B6 of the circuit board 190 in the optical axis direction. For example, the escape groove 24 may be disposed between the first coil unit 230-1 and the fourth coil unit 230-4.

[0461] Although the circuit board 250 and the circuit member 231 are shown as separate components, the present invention is not limited thereto, and in other embodiments, the circuit board 250 and the circuit member 231 may be collectively referred to as the "circuit member" or "substrate." In this case, the other end of the support member field may be coupled to the "circuit member (e.g., the bottom surface of the circuit member)."

[0462] To avoid spatial interference with the support member 220, the corners of the circuit member 231 may be provided with escape grooves 23 through which the support member 220 can pass. Circuit members according to other embodiments may have holes or through holes instead of escape grooves.

[0463] Each of the OIS position sensors 240a, 240b may be a Hall sensor, and any sensor capable of detecting magnetic field strength may be used. For example, each of the OIS position sensors 240a, 240b may be realized as a position detection sensor such as a Hall sensor alone, or may be realized in the form of a driver including a Hall sensor. When the OIS position sensors 240a, 240b are in the form of a driver including a Hall sensor, the description of FIG. 7B may be applied or may be applied mutatis mutandis.

[0464] Each of the OIS position sensors 240a, 240b can sense the strength of the magnetic field of the magnets 130-1 to 130-4 as the OIS movable part moves in a direction perpendicular to the optical axis, and output a signal according to the sensed result. The displacement of the OIS movable part can be sensed using the output signal of each of the OIS position sensors 240a, 240b, and the control units 830, 780 can perform OIS feedback image stabilization using the output signal of the OIS position sensors 240a, 240b.

[0465] For example, the first OIS position sensor 240a may be overlapped on a first line connecting a first corner of the circuit board 250 and the center of the opening (C2) of the circuit board 250. The second OIS position sensor 240b may be overlapped on a second line connecting a second corner of the circuit board 250 and the center of the opening (C2) of the circuit board 250.

[0466] For example, the center of the first OIS position sensor 240a may be aligned with or overlapped by a first line, and the center of the second OIS position sensor 240b may be aligned with or overlapped by a second line, and the first line and the second line may be perpendicular to each other.

[0467] Terminals 251-1 to 251-n can be provided on a terminal surface 253 of the circuit board 250.

[0468] Signals (SCL, SDA, VDD, GND) for data communication with the first position sensor 170 can be transmitted and received via a plurality of terminals 251-1 to 251-n provided on a terminal surface 253 of the circuit board 250, driving signals can be supplied to the OIS position sensors 240a, 240b, and signals output from the OIS position sensors 240a, 240b can be received and output externally.

[0469] According to the embodiment, the circuit board 250 is provided as a flexible printed circuit board (FPCB), but is not limited thereto. The terminals of the circuit board 250 may be directly formed on the surface of the base 210 using a surface electrode method or the like.

[0470] The circuit board 250 may include holes 250a through which the support members 220-1 to 220-4 pass. The positions and number of the holes 250a may correspond to or match the positions and number of the support members 220-1 to 220-4. For example, the holes 250a may be formed adjacent to corners of the circuit board 250 corresponding to each of the support members 220-1 to 220-4, and may correspond to or face the escape grooves 23 of the circuit members 231 in the optical axis direction.

[0471] Each of the support members 220-1 to 220-4 may pass through a hole 250a of the circuit board 250 and be coupled to the pads 31-1 to 31-4 (or circuit patterns) formed on the lower surface of the circuit board 250 via solder or a conductive adhesive member, etc.

[0472] The circuit board 250 may include four pads 31-1 to 31-4 coupled to the support members 220-1 to 220-4, and each of the four pads 31-1 to 31-4 of the circuit board 250 may be electrically connected to a corresponding one of the terminals 251-1 to 251-n of the circuit board 250.

[0473] For example, the pads 31-1 to 31-4 of the circuit board 250 may be formed adjacent to or in contact with the holes 250a of the circuit board 250. For example, the pads 31-1 to 31-4 may be formed to cover the holes 250a of the circuit board 250.

[0474] In other embodiments, the circuit board 250 may not have holes through which the support members pass, and the support members 220-1 to 220-4 may be electrically connected to circuit patterns or pads formed on the upper surface of the circuit board 250 via soldering, a conductive adhesive, etc.

[0475] Or in other embodiments, the support members 220-1 to 220-4 may connect the elastic units 150-1 to 150-4 to the circuit member 231, and may also electrically connect the elastic units 150-1 to 150-4 to the circuit member 231, and the support members 220-1 to 220-4 may be electrically connected to the circuit board 250 via the circuit member 231.

[0476] In this embodiment, since the driving signal is provided directly from the first position sensor 170 to the first coil 120, the number of supporting members can be reduced and the electrical connection structure can be simplified compared to the case where the driving signal is provided directly to the first coil 120 via the circuit board 250.

[0477] In addition, since the first position sensor 170 can be realized by a driver IC capable of measuring temperature, the output of the Hall sensor can be compensated to have minimal change due to temperature changes, or the output of the Hall sensor can be compensated to have a certain slope due to temperature changes, thereby improving the accuracy of AF driving regardless of temperature changes.

[0478] The cover member 300 accommodates the bobbin 110, the first coil 120, the first magnet 130, the housing 140, the upper elastic member 150, the lower elastic member 160, the first position sensor 170, the second magnet 180, the circuit board 190, the support member 220, the second coil 230, the second position sensor 240, and the circuit board 250 within an accommodation space formed together with the base 210.

[0479] The cover member 300 may be in the form of a box having an open bottom and including an upper plate 301 and a side plate 302, and the bottom of the cover member 300 (e.g., the bottom of the side plate 302) may be coupled to the base 210 (e.g., the locking portion 211 and / or the escape portions 212-1 to 212-4). The shape of the upper plate 301 of the cover member 300 may be, but is not limited to, a circle or a polygon, for example, a rectangle or an octagon.

[0480] The cover member 300 may have an opening on an upper plate 301 for exposing a lens (not shown) coupled to the bobbin 110 to external light. The material of the cover member 300 may be a non-magnetic material such as SUS to prevent the cover member 300 from sticking to the first magnet 130, but the cover member 300 may be made of a magnetic material to function as a yoke for improving the electromagnetic force between the first coil 120 and the first magnet 130.

[0481] In order to reduce the length of a path through which the power signals (GND, VDD) are transmitted to the first position sensor 170, the following configuration may be provided.

[0482] First, the first and second terminals B1, B2 of the circuit board 190, to which power signals (GND, VDD) are provided, are electrically connected to the first and second support members 220-1, 220-1 arranged on the first side 141-1 of the housing 140 in which the first position sensor 170 is arranged and the two adjacent corners 142-1, 142-2, thereby reducing the number of paths.

[0483] Furthermore, the first and second terminals B1 and B2 of the circuit board 190 are disposed in the main body portion S1 of the circuit board 190, thereby reducing the number of paths.

[0484] In addition, the first terminal B1 of the circuit board 190 is arranged at one end of the circuit board 190 so that the first terminal B1 of the circuit board 190 overlaps with the first corner portion 142-1 of the housing 140 in the optical axis direction, and the second terminal B2 of the circuit board 190 is arranged at the other end of the circuit board 190 so that the second terminal B2 of the circuit board 190 overlaps with the second corner portion 142-2 of the housing 140 in the optical axis direction, thereby reducing the number of paths.

[0485] Furthermore, the distance (e.g., the shortest distance) between the first terminal B1 of the circuit board 190 and the first support member 220-1 is smaller than the distance (e.g., the shortest distance) between the third terminal B3 of the circuit board 190 and the first support member 220-1 and the distance (e.g., the shortest distance) between the fourth terminal B4 of the circuit board 190 and the first support member 220-1.

[0486] In addition, the distance (e.g., the shortest distance) between the second terminal B2 of the circuit board 190 and the second support member 220-2 is smaller than the distance (e.g., the shortest distance) between the third terminal B3 of the circuit board 190 and the second support member 220-2 and the distance (e.g., the shortest distance) between the fourth terminal B4 of the circuit board 190 and the second support member 220-1.

[0487] As the path is shortened for the reasons described above, the length of each of the first and second extension parts P1, P2 can be reduced, thereby reducing the resistance of the path (e.g., the resistance of the first and second upper elastic units 150-1, 150-2).

[0488] In addition, each of the first upper elastic unit 150-1 connected to the first terminal B1 of the circuit board 190 and the second upper elastic unit 150-2 connected to the second terminal B2 has a first outer frame coupled to the housing 140 but does not have a first inner frame 151 and a first frame connection portion, thereby reducing resistance compared to the second and fourth upper elastic units 150-3 and 150-4.

[0489] For the reasons described above, the embodiment can reduce the length of the path through which the power supply signals (GND, VDD) are transmitted to the first position sensor 170, thereby reducing the resistance of the path (e.g., the resistance of the first and second upper elastic units 150-1, 150-2), thereby preventing a decrease in the power supply signals (GND, VDD), reducing power consumption, and reducing the operating voltage of the driver IC of the first position sensor 170.

[0490] In the embodiment, in order to facilitate soldering for electrical connection with the first to fourth extension portions P1 to P4 of the elastic units 150-1 to 150-4 and improve solderability, the first to sixth terminals B1 to B6 can be arranged on the second surface 19a of the circuit board 190.

[0491] If the first to sixth terminals B1 to B6 were to be arranged on the first surface 19b of the circuit board 190, soldering would become difficult, the solderability would deteriorate, and foreign matter (e.g., contaminants) caused by the soldering could flow into the inside of the lens driving device 100, which could induce malfunction of the lens driving device.

[0492] The third and fourth terminals B3, B4 are disposed between the first terminal B1 and the second terminal B2, and since the circuit board 190 has a structure that extends or protrudes to the first corner portion 142-1 and the second corner portion 142-2 of the housing 140 to reduce the path, a portion of each of the third upper elastic unit 150-3 and the fourth upper elastic unit 150-3 (e.g., the third extension portion P3 or the fourth extension portion P4) can pass through the circuit board 190 and be coupled to the third and fourth terminals B3, B4.

[0493] The fifth and sixth terminals B5, B6 of the circuit board 190 may be disposed on the extension S2 of the circuit board 190 to facilitate coupling with the lower elastic units 160-1, 160-2.

[0494] In the embodiment, the magnetic field interference between the second and third magnets 180, 185 and the first magnet 130 is mitigated, so that the reduction in the AF driving force caused by the magnetic field interference can be prevented, and therefore, the desired AF driving force can be obtained without providing a separate yoke.

[0495] As described above, the embodiment can reduce the number of support members, and the reduction in the number of support members can reduce the size of the lens driver.

[0496] Furthermore, since the number of supporting members is reduced, the resistance of the supporting members can be reduced, current consumption can be reduced, and the sensitivity of the OIS drive can be improved.

[0497] In addition, the thickness of the support members can be increased to obtain the same elastic force while reducing the number of support members, and the increased thickness of the support members can reduce the effect of external impacts on the OIS moving parts.

[0498] 17 is a perspective view of base 210, FIG. 18A is an enlarged view of dotted line portion 11 of base 210 in FIG. 17, and FIG. 18B is a bottom view of FIG. 18A.

[0499] 17 to 18B, the base 210 may have recesses 212-1 to 212-4 formed at the four corners.

[0500] For example, the escape portions 212-1 to 212-4 may be in the form of a recess, a groove, a hole, or a through hole, but are not limited thereto, and may be in the form of a chamfer in other embodiments.

[0501] An escape groove 17 may be formed in a region of the upper surface of the base 210 that corresponds to or overlaps with the solder 9A shown in Fig. 16 in the optical axis direction. For example, the base 210 may have, but is not limited to, four escape grooves 17 corresponding to the solder 39A.

[0502] For example, the escape groove 17 can avoid spatial interference between the solder 39A formed on the underside of the circuit board 250 by soldering and the upper surface of the base 210, thereby preventing damage to the solder 39A, the circuit board 250, and / or the base 210.

[0503] The base 210 may include corners corresponding to the corners 142-1 to 142-4 of the housing 140 in the optical axis direction. For example, the base 210 may include four corners, and the dotted line portion 11 in FIG. 17 may correspond to any one of the corners of the base 210.

[0504] Each of the escape portions 212-1 to 212-4 can be formed in a corresponding one of the corner portions 11 of the base 210.

[0505] Referring to FIG. 18A, for example, the diameter (R) of the escape portions 212-1 to 212-4 may increase from the center 201 of the base 210 toward the corners of the base 210.

[0506] For example, the center 201 of the base 210 may be the spatial center of the base 210. For example, the center 201 of the base 210 may be the center of the opening (C3) of the base 210.

[0507] For example, there may be a gradual increase in diameter (R) of the base 210 in a direction 203 from a center 201 of the base 210 towards an imaginary corner 203 of the base 210 .

[0508] For example, the imaginary corner 203 may be an intersection point between the first straight line 202A and the second straight line 202B. For example, the first straight line 202A may be an imaginary straight line that is parallel to and located on the same plane as any one of the side surfaces 213A of the base 210 adjacent to any one of the escape portions (e.g., 212-2) of the base 210. For example, the second straight line 202B may be an imaginary straight line that is parallel to and located on the same plane as the other side surface 213B of the base 210 adjacent to any one of the escape portions (e.g., 212-2) of the base 210.

[0509] In other embodiments, the escape portions 212-1 to 212-4 may include portions having a constant diameter (R).

[0510] In FIG. 18A, the escape portion (e.g., 212-2) of the base 210 may be in the form of a groove having a curved or bent shape, but is not limited thereto, and it is sufficient if it has a shape suitable for avoiding the support member 220 and for being joined to the inner surface of the corner of the cover member 300 by the adhesive member 290.

[0511] The base 210 may include a groove 310 formed in an upper surface 210A of the base 210 around the recess 212-2. The groove 310 of the base 210 may be located below a lower surface of the circuit board 250. For example, the groove 310 may be disposed between the circuit board 250 and the base 210.

[0512] The groove 310 of the base 210 may alternatively be expressed as an "adhesive discharge groove", an "discharge groove", a "guide groove", an "adhesive discharge guide groove", or a "step portion".

[0513] The groove 310 of the base 210 serves to suppress or block the adhesive member 290 from flowing through the hole 250 a of the circuit board 250 toward one end of the member 220 .

[0514] The groove 310 of the base 210 may be a recess or a groove, for example, recessed from the upper surface 210A of the base 210. Here, the upper surface 210A of the base 210 may be a surface that corresponds to or faces the lower surface of the circuit board 250 in the optical axis direction. For example, the upper surface 210A of the base 210 may be a surface that contacts the lower surface of the circuit board 250.

[0515] The groove 310 of the base 210 may be spaced from the outer surface 311 of the corner portion 11 of the base 210 formed by the recess 212-2 or the recess 212-2.

[0516] For example, the groove 310 of the base 210 may include a bottom surface 10A having a step with the top surface 210A of the base 210 in the optical axis direction, a first sidewall (10B or "first side") connecting one side of the bottom surface 10A to the top surface 210A of the base 210, and a second sidewall (10C or "second side") connecting the other side of the bottom surface 10A to the top surface 210A of the base 210.

[0517] Alternatively, for example, the groove 310 may include a first surface 10A having a step with the upper surface 210A of the base 210, and second surfaces 10B, 10C connecting the first surface 10A and the upper surface 210A of the base 210.

[0518] For example, the bottom surface 10A may be located lower than the top surface 210A of the base 210. For example, the height of the bottom surface 10A based on the bottom surface 210B of the base 210 may be lower than the height of the top surface 210A of the base 210. For example, the first side wall 10B and the second side wall 10B may face each other or be opposed to each other.

[0519] For example, the bottom surface 10A may be parallel to the top surface 210A of the base 210, a first interior angle between the first side wall 10B and the bottom surface 10A may be a right angle, and a second interior angle between the second side wall 10C and the bottom surface 10A may be a right angle, but is not limited thereto. In other embodiments, each of the first interior angle and the second interior angle may be an obtuse angle or an acute angle.

[0520] For example, one end of the groove 310 may be open to one outer surface 213A of the base 210 adjacent to the escape portion 212-2, and the other end of the groove 310 may be open to another outer surface 213B of the base 210 adjacent to the escape portion 212-2.

[0521] For example, the groove 310 may have at least one of a first opening HO1 opening to one outer side surface 213A of the base 210 adjacent to the escape portion 212-2 and a second opening HO2 opening to another outer side surface 213B of the base 210 adjacent to the escape portion 212-2. This is to allow the adhesive member 290 to escape to the outside of the base 210 through the first opening HO1 and the second opening HO2.

[0522] The distance from one end (or the first opening HO1) of the groove 310 to the other end (or the second opening HO2) may be greater than the width of the groove 310 (or the width of the bottom surface 10A).

[0523] For example, the shape of the groove 310 can correspond to or match the shape of the outer surface 311 of the corner or relief of the base 210 .

[0524] The shape of the outer surface 311 of the corner portion of the base 210 may include at least one curved or rounded portion. For example, referring to Fig. 18A, the shape of the outer surface 311 of the corner portion of the base 210 may include three curved or rounded portions, and may be symmetrical with respect to the curved and rounded portions located in the middle, but is not limited thereto.

[0525] For example, the base 210 may have a partition 330 between the groove 310 and the escape portion 212-2. The partition 330 may function to prevent or block the adhesive member 290 from penetrating into the hole 250a of the circuit board 250.

[0526] Although not limited thereto, a portion of the adhesive member 290 may be disposed or remain in the groove 310 of the base 210. In other embodiments, a portion of the adhesive member 290 may not be disposed or remain in the groove 310 of the base 210.

[0527] 18B and 18C, a step portion 320 having a step with the lower surface 210B of the base 210 in the optical axis direction may be formed on the lower surface of the corner portion of the base 210 adjacent to the escape portions 212-1 to 212-4. The step portion 320 may be alternatively expressed as a "groove" or a "groove portion".

[0528] For example, the step portion 320 may be formed on the lower surface of the base 210 around the escape portions 212-1 to 212-4, or the step portion 320 may be formed to cover at least a portion of the escape portions 212-1 to 212-4.

[0529] For example, the step portion 320 may be disposed between the lower surface of the base 210 and the adhesive member 290 .

[0530] For example, the step portion 320 may include a first surface 321 having a step H2 with the lower surface 210B of the base 210 in the optical axis direction, and a second surface 322 connecting the first surface 321 and the lower surface 210B of the base 210.

[0531] First surface 321 of step portion 320 may be located higher than bottom surface 210B of base 210. For example, the length in the optical axis direction from top surface 210A of base 210 to first surface 321 of step portion 320 may be smaller than the length in the optical axis direction from top surface 210A of base 210 to bottom surface 210B of base 210.

[0532] For example, the distance from the upper surface 210A of the base 210 to the bottom surface 10A of the groove 310 (or the depth H1 of the groove) may be smaller than or equal to the step H2 of the stepped portion 320 (H1≦H2). In other embodiments, H1>H2 may be satisfied. For example, H2 may be the height of the first surface 321 with respect to the lower surface of the base 210.

[0533] For example, first surface 321 of step portion 320 may contact escape portions 212-1 to 212-4. Or, for example, first surface 321 of step portion 320 may contact outer surface 311 of corner portion 11 of base 210 formed by escape portion 212-2.

[0534] For example, the step portion 320 may overlap the groove 310 of the base 210 in the optical axis direction.

[0535] For example, one end of the step portion 320 may contact one outer surface 213A of the base 210 adjacent to the escape portion (e.g., 212-2), and the other end of the step portion 320 may contact another outer surface 213B of the base 210 adjacent to the escape portion (e.g., 212-2). This is to increase the contact area between the step portion 320 of the base 210 and the adhesive member 290 to improve the adhesive force between the base 210 and the cover member 300, and to lengthen the flow path of the adhesive member 290 to prevent the adhesive member 290 from penetrating the upper surface of the circuit board 250 and flowing into the upper part of the hole 250a of the circuit board 250.

[0536] In another embodiment, at least one of the ends of the step portion 320 may be spaced apart from the outer surfaces 213A, 213B of the base 210 adjacent to the recess (eg, 212-2) without contacting them.

[0537] For example, the width W2 of the first surface 321 of the stepped portion 320 may be greater than the width W1 of the groove 310 of the base 210. This is to increase the contact area between the stepped portion 320 of the base 210 and the adhesive member 290 to improve the adhesive force between the base 210 and the cover member 300, and to prevent the adhesive member 290 from penetrating the upper surface of the circuit board 250 and flowing into the upper part of the hole 250a of the circuit board 250 by making the flow path of the adhesive member 290 complex and long.

[0538] In the embodiment, the step portion 320 of the base 210 has a double step structure having one step, but is not limited thereto. In other embodiments, the step portion of the base may have a triple step structure having two or more steps based on the lower surface of the base.

[0539] In yet another embodiment, instead of the stepped portion 320, a groove having the shape and structure of the groove 310 described above may be formed on the underside of the base 210, and the description of the groove 310 may be applied mutatis mutandis.

[0540] In other embodiments, the base may include at least one of the groove 310 and the step 320 .

[0541] The adhesive member 290 may include a plurality of adhesive members 290-1 to 290-4.

[0542] Each of the adhesive members 290-1 to 290-2 can join a corresponding one of the escape portions 212-1 to 212-4 of the base 210 to a corresponding one of the corners of the side plate 302 of the cover member 300.

[0543] As shown in FIG. 16, for example, at least some of the adhesive members 290-1 to 290-4 may have a curved or rounded shape, but is not limited thereto.

[0544] The adhesive member 290 may be an insulating adhesive, such as, but not limited to, epoxy, epoxy bond, or silicone.

[0545] The description of any one of the escape portions 212-2, groove 310, and step portion 320 formed in any one of the corner portions of the base 210 shown in Figures 18A to 19B can also be applied to the escape portions 212-1, 212-3, 212-4, groove 31, and step portion 320 formed in the remaining corner portions of the base 210.

[0546] The shape of the escape portions 212-1 to 212-4 may include at least one curved or rounded portion. For example, referring to Fig. 18A, the shape of the escape portions 212-1 to 212-4 may include three curved or rounded portions and may have a symmetrical shape with respect to the central curved portion, but is not limited thereto.

[0547] The coupling of the second coil 230, the circuit board 250, the support member 220, and the base 210 may be carried out as follows.

[0548] First, the upper elastic member 150 and the lower elastic member 160 are coupled to the bobbin 110 to which the first coil 120, the second and third magnets 180, 185 are coupled, the housing 140 to which the first magnet 130, the circuit board 190, the first position sensor 170, and the capacitor 195 are mounted, and electrical connection is made between the upper and lower elastic members 150, 160 and the circuit board 190 by soldering or the like.

[0549] Next, the base 210, the circuit board 250, and the second coil 230 are joined together.

[0550] Next, the support member 220 is passed through the hole 250a of the circuit board 250 and the escape groove 23 of the second coil 230, and one end of the member 220 is connected to the upper elastic member 150 by soldering or the like, and the other end of the support member 220 is connected to the pads 31-1 to 31-4 formed on the lower surface of the circuit board 250. Then, the combined assembly is placed inside the cover member 300.

[0551] 19A shows a bottom view of the lens driving device 100 before the adhesive members 290-1 to 290-4 are applied, and FIG. 19B shows a bottom view of the support member 220 coupled to the step portion 320 of the base 210 and the lower surface of the circuit board 250. As shown in FIG.

[0552] 19A and 19B, adhesive members 290-1 to 290-3 may be disposed on escape portions 212-1 to 212-4 of base 210, a region (e.g., a first region) of the underside of circuit board 250 exposed by escape portions 212-1 to 212-4, solder 902 connecting the other ends of support members 220-1 to 220-4 to pads 27a to 27d of circuit board 250, and the inner surfaces (or inner surfaces) of corners 305-1 to 305-4 of cover member 300.

[0553] For example, the adhesive members 290-1 to 290-4 may also be disposed on an area (e.g., a first area) of the underside of the base 210 adjacent to the escape portions 212-1 to 212-4 of the base 210. In addition, for example, the adhesive members 290-1 to 290-4 may be disposed on an area of ​​the inner surface of the side plate of the cover member 300 adjacent to the inner surfaces of the corners 305-1 to 305-4 of the cover member 300.

[0554] Since the bottom of the hole 250a of the circuit board 250 is sealed or blocked by the solder 902, the adhesive material 290 does not flow into the inside of the hole 250a through the bottom of the hole 250a of the circuit board 250 or the lower opening of the hole 250a.

[0555] 20A shows a flow path 24 of the adhesive material when the adhesive material is applied to the escape portion of a base 21A that does not include the groove 310 and the step portion 320 of the base 210 according to the embodiment. The base 21A may have the same structure as the base 210 except for the groove 310 and the step portion 320.

[0556] 20A, the adhesive material applied to the escape portion of the base 21A may overflow inside the circuit board 250, and as a result, the adhesive material may flow onto the upper surface of the corner portion of the circuit board 250 through a gap between the lower surface of the circuit board 250 and the upper surface of the base 21A, and may flow into the upper portion of the hole 250a of the circuit board 250 or into the upper opening of the hole 250a to fill the hole 250a. Arrows 24 in FIG. 20A indicate the flow path of the adhesive material in FIG. 20A.

[0557] Fig. 21A shows a break in the support member that occurred in the actual product in the case of Fig. 20A. Fig. 21A shows the upper surface side of a corner portion of circuit board 250, and shows the state in which the support member has been broken and removed.

[0558] 21A, in the case of Fig. 20A, the hole 250a and a region of the support member 220 located within the hole 250a may be bonded or bonded to each other by the adhesive material flowing into the hole 250a. The arrow in Fig. 21A indicates the adhesive material flowing into the hole 250a.

[0559] The length of the support member coupled between the upper elastic member 150 and the circuit board 250 in the effective optical axis direction may be reduced, and the brittleness of the support member may increase, which may weaken its reliability in the event of an external impact and cause the member to break, ultimately causing the lens driving device to become unable to operate due to the breakage of the support member.

[0560] Fig. 20B shows a flow path 25 of adhesive material 290 when adhesive material 290 is applied to escape portions 212-1 to 212-4 of base 210 according to the embodiment, and Fig. 21B shows that no breakage of the support member occurs in an actual product in the case of Fig. 20B. Arrows 25 in Fig. 20B show the flow path of the adhesive material in Fig. 20B, and Fig. 21B shows the upper surface side of a corner portion of circuit board 250 according to the embodiment.

[0561] 18A to 20B and 21B, the base 210 of the embodiment has a step portion 320 having two or more steps, which makes the flow path of the adhesive material 290 complex and long, thereby preventing the adhesive material from overflowing or penetrating the upper surface of the circuit board 250.

[0562] In addition, the base 210 of the embodiment has a groove 310, which allows the adhesive material 290 that has overflowed or permeated the upper surface of the circuit board 250 to circulate or be discharged outside the outer surfaces 213A, 213B of the base 210 through the groove 310, thereby preventing or blocking the adhesive material 290 from flowing into the upper part of the hole 250a of the circuit board 250 or into the upper opening of the hole 250a.

[0563] 22A shows the positional relationship between the groove 310 of the base 210 and the first groove 41A of the circuit board 250, and FIG. 22B shows the positional relationship between the groove 310 of the base 210 and the second groove 41B of the circuit board 250. As shown in FIG.

[0564] 22A, the circuit board 250 may include a first groove 41A formed in a first side surface 51A of the circuit board 253 where the terminal portion 253 is bent.

[0565] For example, the first groove 41A of the circuit board 250 may be formed adjacent to or in contact with the terminal portion 253. The circuit board 250 may include four first grooves 41A, but is not limited to this, and in other embodiments, the number of first grooves 41A may be two or more.

[0566] For example, the first groove 41A of the circuit board 250 can serve to allow the terminal portion 253 to be easily bent.

[0567] The shape of the first groove 41A may be a semicircle, an inverse ellipse, or a curved shape, but is not limited thereto, and may also be a polygonal shape.

[0568] For example, the groove 310 of the base 210 and the first groove 41A of the circuit board 250 do not have to overlap each other in the optical axis direction.

[0569] For example, the first groove 41A can be disposed between the terminal portion 253 and a corner of the circuit board 250.

[0570] For example, the first groove 41A of the circuit board 250 may be located on the opposite side of the support member 220 (or the corner 60 of the circuit board 250) from the groove 310 of the base 210.

[0571] For example, the first opening HO1 of the groove 310 in the base 210 can be located closer to the support member 220 (or the corner 60 of the circuit board 250) than the first groove 41A of the circuit board 250.

[0572] The first groove 41A of the circuit board 250 allows the first region 210A1 of the upper surface 210A of the base 210 to be exposed.

[0573] For example, the groove 310 of the base 210 and the first region 210A1 of the upper surface 210A of the base 210 do not have to overlap each other in the optical axis direction.

[0574] For example, the first region 210A1 can be spaced apart from the groove 310 of the base 210.

[0575] The first region 210A1 of the upper surface 210A of the base 210 may be located on the opposite side to the support member 220 (or the corner 60 of the circuit board 250) with respect to the groove 310 of the base 210.

[0576] The first opening HO1 of the groove 310 in the base 210 may be located closer to the support member 220 (or the corner 60 of the circuit board 250) than the first region 210A1 of the top surface 210A of the base 210.

[0577] 22B, the circuit board 250 may include a second groove 41B formed in a second side surface 51B adjacent to the first side surface 51A. A corner 60 may be where the first side surface 51A meets the second side surface 51B. The circuit board 250 may include, but is not limited to, four second grooves, and in other embodiments, there may be five or more second grooves.

[0578] The shape of the second groove 41B may be, but is not limited to, a semicircle, an inverse ellipse, or a curved shape, and may also be a polygon.

[0579] For example, after producing multiple circuit boards connected by bridges, a single circuit board 250 according to the embodiment is produced by cutting the bridges, and the second groove 41B may be the portion where the bridges are connected.

[0580] For example, the groove 310 of the base 210 and the second groove 41B of the circuit board 250 do not have to overlap with each other in the optical axis direction.

[0581] For example, the second grooves 41B can be disposed between the terminals 30A to 30D of the circuit board 250 and the corners 60 of the circuit board 250.

[0582] The second groove 41B of the circuit board 250 may be located on the opposite side of the support member 220 (or the corner 60 of the circuit board 250) with respect to the groove 310 of the base 210.

[0583] For example, the second opening HO2 of the groove 310 in the base 210 can be located closer to the support member 220 (or the corner 60 of the circuit board 250) than the second groove 41B of the circuit board 250.

[0584] The second groove 41B of the circuit board 250 allows the second region 210A2 on the upper surface of the base 210 to be exposed.

[0585] For example, the groove 310 of the base 210 and the second region 210A2 of the upper surface 210A of the base 210 do not have to overlap with each other in the optical axis direction.

[0586] The second region 210A2 of the upper surface of the base 210 may be located on the opposite side of the support member 220 (or the corner 60 of the circuit board 250) with respect to the groove 310 of the base 210.

[0587] The second opening HO2 of the groove 310 of the base 210 may be located closer to the support member 220 (or the corner 60 of the circuit board 250) than the second region 210A2 of the top surface 210A of the base 210.

[0588] The adhesive material 290 that flows into the first region 210A1 and / or the second region 210A2 of the upper surface 210A of the base 210 and flows into the gap between the upper surface of the base 210 and the lower surface of the circuit board 250 can flow out or be discharged outside the outer surface of the base 210 through the groove 310 of the base 210.

[0589] FIG. 23A shows another embodiment of the positional relationship between the groove 310 of the base 210 and the first groove 42A of the circuit board 250, and FIG. 23B shows another embodiment of the positional relationship between the groove 310 of the base 210 and the second groove 42B of the circuit board 250.

[0590] The first groove 42A in FIG. 23A may be a modified version of the first groove 41A in FIG. 22A, and the second groove 42B in FIG. 23B may be a modified version of the second groove 41B in FIG. 22B.

[0591] For example, each of the first groove 42A and the second groove 42B may have a shape including, but not limited to, a semicircular shape, an inverse elliptical shape, or a curved shape, and may also have a polygonal shape.

[0592] For example, a portion of the groove 310 of the base 210 and the first groove 42A of the circuit board 250 can overlap with each other in the optical axis direction, and another portion of the groove 310 of the base 210 and the second groove 42B of the circuit board 250 can overlap with each other in the optical axis direction.

[0593] For example, the first groove 42A can be arranged between the terminal portion 253 and the corner 60 of the circuit board 250, and the second groove 42B can be arranged between the terminals 30A to 30D of the circuit board 250 and the corner 60 of the circuit board 250.

[0594] The first groove 42A may expose a portion (or one end) of the groove 310 of the base 210, and the second groove 42B may expose another portion (or the other end) of the groove 310 of the base 210.

[0595] One end of the first groove 42A can extend to the escape portions 122-1 to 122-4 of the base 210, and one end of the second groove 42B can extend to the escape portions 122-1 to 122-4 of the base 210.

[0596] Since at least a portion of the groove 310 of the base 210 is exposed by the first groove 42A and the second groove 42B, the adhesive material flowing into the first region 210A3 of the upper surface 210A of the base 210 exposed by the first groove 42A and / or the second region 210A4 of the base 210 exposed by the second groove 42B can easily flow into the groove 310 of the base 210 and flow out or be released outside the outer surface of the base 210, thereby improving the release effect of the adhesive material.

[0597] Fig. 24 shows a second coil 230A including a circuit member 231A according to another embodiment. Referring to Fig. 24, the circuit member 231A may have through holes 23A through which the support members 220-1 to 220-4 pass. The contents described with reference to Figs. 13 to 23B may be applied or mutatis mutandis to the embodiment of Fig. 24.

[0598] Meanwhile, the lens driving device according to the above-described embodiments can be used in various fields, for example, in a camera module or an optical device.

[0601] The lens barrel 400 can be attached to the bobbin 110 of the lens driving device 100 .

[0602] The first holder 600 may be disposed under the base 210 of the lens driving device 100. The filter 610 is mounted on the first holder 600, and the first holder 600 may include a protrusion 500 on which the filter 610 is seated.

[0603] The adhesive member 612 may couple or attach the base 210 of the lens driving device 100 to the first holder 600. The adhesive member 612 may also serve to prevent foreign matter from entering the inside of the lens driving device 100 in addition to the above-mentioned adhesive function.

[0604] For example, the adhesive member 612 can be an epoxy, a heat curable adhesive, a UV curable adhesive, or the like.

[0605] The filter 610 may function to block light of a specific frequency band from passing through the lens barrel 400 from entering the image sensor 810. The filter 610 may be, but is not limited to, an infrared blocking filter. In this case, the filter 610 may be disposed parallel to the xy plane.

[0606] An opening may be formed in the portion of the first holder 600 where the filter 610 is mounted so that light passing through the filter 610 can be incident on the image sensor 810 .

[0607] The second holder 800 is disposed under the first holder 600, and an image sensor 810 may be mounted on the second holder 800. The image sensor 810 is a portion where light passing through the filter 610 is incident and an image contained in the light is formed.

[0608] The second holder 800 may include various circuits, elements, controllers, etc. for converting an image formed on the image sensor 810 into an electrical signal and transmitting the signal to an external device.

[0609] The second holder 800 may be realized as a circuit board on which an image sensor may be mounted, a circuit pattern may be formed, and various elements may be coupled. The first holder 600 may be alternatively referred to as a "holder" or a "sensor base", and the second holder 800 may be alternatively referred to as a "substrate" or a "circuit board".

[0610] The image sensor 810 may receive an image contained in light incident through the lens driving device 100 and convert the received image into an electrical signal.

[0611] The filter 610 and the image sensor 810 may be disposed apart from each other and facing each other in a first direction.

[0612] The motion sensor 820 may be mounted on the second holder 800 and electrically connected to the control unit 830 via a circuit pattern provided on the second holder 800 .

[0613] The motion sensor 820 outputs rotational angular velocity information according to the movement of the camera module 200. The motion sensor 820 may be realized by a two-axis or three-axis gyro sensor, or an angular velocity sensor.

[0614] The controller 830 may be mounted on the second holder 800 and electrically connected to the second position sensor 240 and the second coil 230 of the lens driving device 100 .

[0615] For example, the second holder 800 may be electrically connected to the circuit board 250 of the lens driving device 100, and the control unit 830 mounted on the second holder 800 may be electrically connected to the second position sensor 240 and the second coil 230 via the circuit board 250.

[0616] The control unit 830 can transmit a clock signal (SCL), a data signal (SDA), and a power supply signal (VDD, GND) for I2C communication with the first position sensor 170, and can receive the clock signal (SCL) and the data signal (SDA) from the first position sensor 170.

[0617] In addition, the control unit 830 can control a drive signal that can perform image stabilization for the OIS movable part of the lens driving device 100 based on the output provided from the second position sensor 240 of the lens driving device 100, etc.

[0618] The connector 840 is electrically connected to the second holder 800 and may include a port for electrically connecting to an external device.

[0619] In addition, the lens driving device 100 according to the embodiment may be included in an optical instrument that aims to enhance the eyesight by forming an image of an object in space using the characteristics of light such as reflection, refraction, absorption, interference, diffraction, etc., or aims to record and reproduce an image by a lens, or aims to optically measure, propagate or transmit an image, etc. For example, the optical instrument according to the embodiment may be a mobile phone, a smart phone, a portable smart device, a digital camera, a laptop computer, a digital broadcasting terminal, a PDA (Personal Digital Assistant), a PMP (Portable Multimedia Player), a navigation system, etc., but is not limited thereto and may be any device for taking images or photographs.

[0620] FIG. 26 shows a perspective view of a portable terminal 200A according to an embodiment, and FIG. 27 shows a configuration diagram of the portable terminal shown in FIG.

[0621] Referring to Figures 26 and 27, a portable terminal (200A, hereinafter referred to as the "terminal") may include a main body 850, a wireless communication unit 710, an A / V input unit 720, a sensing unit 740, an input / output unit 750, a memory unit 760, an interface unit 770, a control unit 780, and a power supply unit 790.

[0693] In this embodiment, the second magnet 1610 may be prevented from being exposed to UV beams and heat conduction may be blocked due to the shape of the upper elastic member 1510. In this embodiment, the upper surface 1611 of the second magnet 1610, which would be open if there was no first region 1514 of the upper elastic member 1510, may be closed by the first region 1514.

[0694] In this embodiment, a UV beam can be used to harden the epoxy that fixes the lens module 1020 to the bobbin 1210. Also, a UV beam can be used to fix the upper elastic member 1510 to the bobbin 1210. The UV beam for hardening the epoxy that fixes the lens module 1020 to the bobbin 1210 can be irradiated after the cover 1100 is assembled. Also, the UV beam for fixing the upper elastic member 1510 to the bobbin 1210 can be irradiated before the cover 1100 is assembled. The first region 1514 of the upper elastic member 1510 can prevent the UV beam from affecting the magnetic force of the second magnet 1610 both before and after the cover 1100 is assembled.

[0695] The first region 1514 of the upper elastic member 1510 may extend from the inner part 1511 of the upper elastic member 1510 in a direction opposite to the connecting part 1513 of the upper elastic member 1510.

[0696] In this embodiment, a gap may be formed between the first region 1514 of the upper elastic member 1510 and the second magnet 1610 in the optical axis direction without the bobbin 1210 being disposed therebetween. If the lens driving device 1010 has a sufficient height in the optical axis direction, a part of the bobbin 1210 is disposed between the first region 1514 of the upper elastic member 1510 and the second magnet 1610, but since the lens driving device 1010 according to this embodiment has a minimized length in the optical axis direction due to a requirement for an ultra-thin shape, it may be impossible to dispose a part of the bobbin 1210 above the second magnet 1610. An adhesive may be disposed in the gap.

[0697] In this embodiment, an adhesive that is cured by UV can fix the lens to the bobbin 1210. If the first region 1514 of the upper elastic member 1510 of this embodiment does not exist, a problem may occur in which the characteristics of the second magnet 1610 change due to heat generated by a UV beam irradiated from above to harden the adhesive for fixing the lens. That is, the first region 1514 of the elastic member 1510 according to this embodiment can prevent the UV beam from being irradiated to the second magnet 1610, thereby preventing a thermal demagnetization phenomenon of the second magnet 1610. The UV beam can be irradiated in a state where the cover 1100 is assembled. Alternatively, the UV beam can be irradiated in a state where the cover 1100 is not assembled.

[0698] In the modified example, the upper surface 1611 of the second magnet 1610 may come into contact with the first region 1514 of the upper elastic member 1510. When the height of the lens driving device 1010 in the optical axis direction is further reduced, the upper surface 1611 of the second magnet 1610 and the first region 1514 of the upper elastic member 1510 may come into contact with each other without creating a gap between them as in the modified example. Even in this case, the first region 1514 of the upper elastic member 1510 may prevent the UV beam from being irradiated onto the second magnet 1610, thereby preventing the characteristic change phenomenon of the second magnet 1610.

[0699] In this embodiment, the upper elastic member 1510 may be disposed on an upper surface 1211 of the bobbin 1210. The upper surface 1211 of the bobbin 1210 may be disposed at a higher position than an upper surface 1611 of the second magnet 1610, so that the second magnet 1610 may not protrude above the bobbin 1210.

[0751] The operation of the camera device according to the second embodiment of the present invention will be described below.

[0752] The autofocus function of the camera apparatus according to the second embodiment of the present invention will be described. When power is supplied to the first coil 1220, the first coil 1220 moves relative to the first magnet 1320 due to electromagnetic interaction between the first coil 1220 and the first magnet 1320. At this time, the bobbin 1210 to which the first coil 1220 is coupled moves together with the first coil 1220. That is, the bobbin 1210 to which the lens module 1020 is coupled moves in the optical axis direction relative to the housing 1310. Such movement of the bobbin 1210 results in the lens module 1020 moving closer to or farther away from the image sensor 1060, so in this embodiment, power is supplied to the first coil 1220 to perform focus adjustment on the subject. Meanwhile, the above-mentioned focus adjustment can be automatically performed according to the distance of the subject.

[0753] In the camera apparatus according to this embodiment, autofocus feedback control can be performed to achieve a more precise autofocus function. The sensor 1630 disposed in the housing 1310 senses the magnetic field of the second magnet 1610 disposed in the bobbin 1210. Therefore, when the bobbin 1210 moves relative to the housing 1310, the amount of the magnetic field sensed by the sensor 1630 changes. In this manner, the sensor 1630 senses the amount of movement of the bobbin 1210 in the optical axis direction or the position of the bobbin 1210, and transmits the sensed value to the controller. The controller determines whether to perform additional movement of the bobbin 1210 according to the received sensed value. Since this process occurs in real time, the autofocus function of the camera apparatus according to this embodiment can be performed more precisely through the autofocus feedback control.

[0754] The image stabilization function of the camera device according to the present embodiment will be described. When power is supplied to the second coil 1430, the first magnet 1320 moves relative to the second coil 1430 due to electromagnetic interaction between the second coil 1430 and the first magnet 1320. At this time, the housing 1310 to which the first magnet 1320 is coupled moves together with the first magnet 1320. That is, the housing 1310 moves in a direction perpendicular to the horizontal optical axis relative to the base 1410. However, at this time, tilt of the housing 1310 may be induced relative to the base 1410. Meanwhile, the bobbin 1210 moves together with the housing 1310 with respect to the horizontal movement of the housing 1310. Therefore, such movement of the housing 1310 results in the lens module 1020 coupled to the bobbin 1210 moving in a direction parallel to the direction in which the image sensor 1060 is placed relative to the image sensor 1060. That is, in this embodiment, the camera shake correction function can be performed by supplying power to the second coil 1430.

[0755] In the camera apparatus according to the present embodiment, a camera shake correction feedback control can be performed to achieve a more precise camera shake correction function. The OIS sensor 1650 disposed in the base 1410 detects the magnetic field of the first magnet 1320 disposed in the housing 1310. Therefore, when the housing 1310 moves relative to the base 1410, the amount of the magnetic field detected by the OIS sensor 1650 changes. In this manner, the pair of OIS sensors 1650 detect the amount of movement or position of the housing 1310 in the horizontal x-axis and y-axis directions and transmit the detection value to the controller. The controller determines whether to perform additional movement of the housing 1310 according to the received detection value. Since this process occurs in real time, the camera shake correction function of the camera apparatus according to the present embodiment can be performed more precisely through the camera shake correction feedback control.

For example, the horizontal or lateral length of each of the first sides 2110b-1 of the bobbin 2110 may be different from the horizontal or lateral length of each of the second sides 2110b-2. For example, the horizontal length of the first side 2110b-1 may be greater than the horizontal length of the second side 2110b-2, but is not limited thereto, and in other embodiments, the former may be the same or smaller than the latter.

[0768] The bobbin 2110 may include a protrusion 2115 disposed on an outer surface.

[0769] For example, but not limited to, the protrusion 2115 is disposed on the outer surface of the second side portion 2110b-2 of the bobbin 2110. The protrusion 2115 may protrude in a direction parallel to a straight line that passes through the center of the opening of the bobbin 2110 and is perpendicular to the optical axis, but is not limited to this.

[0770] The protrusion 2115 of the bobbin 2110 corresponds to the groove 2025a of the housing 2140 and is inserted or positioned within the groove 2025a of the housing 2140 to suppress or prevent the bobbin 2110 from rotating more than a certain range around the optical axis.

[0771] In addition, the protrusion 2115 can act as a stopper that suppresses or prevents the lower surface of the bobbin 2110 from directly colliding with the base 2210, the second coil 2230, or the circuit board 2250 even if the bobbin 2110 moves more than a specified range in the optical axis direction (e.g., the direction from the upper elastic member 2150 to the lower elastic member 2160) due to an external impact, etc.

[0772] A first escape groove 2112a may be provided on the upper surface of the bobbin 2110 to avoid spatial interference with the first frame connecting portion 2153 of the upper elastic member 2150. For example, the first escape groove 2112a may be disposed on the second side portion 2110b-2 of the bobbin 2110, but is not limited thereto.

For example, as illustrated in Fig. 48A, the guide portion 2111 of the bobbin 2110 may be disposed in a first escape groove 2112a to guide the path through which the frame connecting portion 2153 of the upper elastic member 2150 passes. For example, the guide portion 2111 may protrude in the optical axis direction from a bottom surface of the first escape groove 2112a.

[0774] In addition, a damper may be disposed between the guide portion 2111 and the first frame connecting portion 2153 of the upper elastic member 2150 .

[0775] The bobbin 2110 may include a stopper 2116 protruding from a top surface.

[0776] The stopper 2116 of the bobbin 2110 can prevent the top surface of the bobbin 2110 from directly colliding with the inside of the top plate of the cover member 2300 even if the bobbin 2110 moves beyond a specified range due to an external impact or the like when the bobbin 2110 moves in a first direction for the autofocusing function.

[0777] The bobbin 2110 may include a first coupling portion 2113 formed on the top or upper surface of the bobbin 2110 to be coupled and fixed to the upper elastic member 2150. For example, in FIG. 48A, the first coupling portion 2113 of the bobbin 2110 is in the form of a protrusion, but is not limited thereto, and in other embodiments, the first coupling portion 2113 of the bobbin 2110 may be in the form of a groove or a flat surface.

[0778] The bobbin 2110 may also include a second coupling portion 2117 formed on the lower portion or underside of the bobbin 2110 to be coupled and fixed to the lower elastic member 2160. In FIG. 48B, the second coupling portion 2117 of the bobbin 2110 is in the form of a protrusion, but is not limited thereto, and in other embodiments, the second coupling portion of the bobbin 2110 may be in the form of a groove or a flat surface.

[0779] A seating groove 2105 in which the first coil 2120 is seated, inserted or disposed may be provided on an outer surface of the bobbin 2110. The seating groove 2105 may have a groove structure recessed from the outer surfaces of the first and second sides 2110b-1 and 2110b-2 of the bobbin 2110, and may have a shape that matches the shape of the first coil 2120, such as a closed curve shape (e.g., a ring shape).

[0780] In addition, when the coil 2120 is connected to the lower elastic members 2160-1 and 2160-2, in order to prevent the coil 2120 from coming off and to guide both ends of the coil 2120, guide grooves 2116a and 2116b may be provided on the lower surfaces of the two first side portions 2110b-1 or the two second side portions 2110b-2 located on opposite sides of the bobbin 2110.

[0781] In addition, a seating groove 2180a may be provided on the outer surface of the bobbin 2110, in which the second magnet 2180 is seated, inserted, fixed or disposed.

[0782] The seating groove 2180a of the bobbin 2110 may have a structure recessed from the outer surface of the bobbin 2110, and may have an opening on at least one of the upper surface or the lower surface of the bobbin 2110, but is not limited thereto.

[0783] In addition, a seating groove 2185a may be provided on the outer surface of the bobbin 2110 for seating, inserting, fixing or positioning the third magnet 2185 therein.

[0784] The seating groove 2185a of the bobbin 2110 may have a structure recessed from the outer surface of the bobbin 2110, and may have an opening on at least one of the upper surface or the lower surface of the bobbin 2110, but is not limited thereto.

[0785] Each of the seating grooves 2180a, 2185a of the bobbin 2110 is located above the seating groove 2105 in which the first coil 2120 is disposed, and may be connected or in contact with the seating groove 2105, but is not limited to this, and in other embodiments, the two may be spaced apart from each other.

[0786] The seating groove 2180a of the bobbin 2110 may be provided on one side of the first side 2110b-1 of the bobbin 2110, and the seating groove 2185a of the bobbin 2110 may be provided on the other side of the first side 2110b-2 of the bobbin 2110.

[0787] For example, the seating grooves 2180a, 2185a may be disposed on two first sides of the bobbin 2110 facing each other or on two first sides located on opposite sides.

[0788] The second magnet 2180 and the third magnet 2185 are disposed in the seating grooves 2180a, 2185a provided on the two first sides located on opposite sides of the bobbin 2110, so that the weights of the second magnet 2180 and the third magnet 2185 can be balanced, and the influence of the AF driving force due to the magnetic field interference between the first magnet 2130 and the second magnet 2180 and the influence of the AF driving force due to the magnetic field interference between the first magnet 2130 and the third magnet 2185 can be offset each other, thereby improving the accuracy of the AF (Auto Focusing) drive in this embodiment.

[0789] The bobbin 2110 may have a screw thread 211 for coupling with a lens or a lens barrel on its inner circumferential surface. The screw thread 211 may be formed on the inner circumferential surface of the bobbin 2110 in a state where the bobbin 2110 is fixed by a jig or the like, and the bobbin 2110 may have jig fixing grooves 2015a and 2015b on its upper surface. For example, the jig fixing grooves 2015a and 2015b may be provided on the upper surfaces of two first side portions 2110b-1 or two second side portions 2110b-1 located on opposite sides of the bobbin 2110, but are not limited thereto. The jig fixing grooves 2015a and 2015b may function as a foreign matter collector for collecting foreign matter.

[0790] Next, the first coil 2120 will be described. The first coil 2120 is disposed on the outer surface of the bobbin 2110 .

[0791] The first coil 2120 is disposed below the second and third magnets 2180, 2185, but is not limited to this. For example, the first coil 2120 is disposed below the protruding portion 2115 of the bobbin 2110, but is not limited to this.

[0792] For example, but not limited to, the first coil 2120 does not overlap the second and third magnets 2180, 2185 in a direction perpendicular to the optical axis. In other embodiments, the first coil may overlap at least a portion of each of the second and third magnets 2180, 2185 in a direction perpendicular to the optical axis.

[0793] For example, the first coil 2120 may be positioned in the mounting groove 2105 of the bobbin 2110, the second magnet 2180 may be inserted or positioned in the mounting groove 2180a of the bobbin 2110, and the third magnet 2185 may be inserted or positioned in the mounting groove 2185a of the bobbin 2110.

[0794] Each of the second magnet 2180 and the third magnet 2185 arranged on the bobbin 2110 may be separated from the first coil 2120 in the optical axis (OA) direction, but is not limited to this. In other embodiments, each of the second magnet 2180 and the third magnet 2185 arranged on the bobbin 2110 may be in contact with the first coil 2120 or overlap with a portion of the first coil 2120 in a direction perpendicular to the optical axis.

[0795] The first coil 2120 may cover the outer surface of the bobbin 2110 in a direction rotating about the optical axis (OA). For example, the first coil 2120 may have a closed curve, for example a ring shape, wound around the outer surface of the bobbin 2110.

[0796] The first coil 2120 may be wound directly on the outer surface of the bobbin 2110, but is not limited to this. In other embodiments, the first coil 2120 may be wound around the bobbin 2110 using a coil ring, or may be provided as an angular ring-shaped coil block.

[0797] In another embodiment, the first coil may be in the form of a coil ring wound on a line perpendicular to the optical axis and passing through the optical axis.

[0798] A power source or a drive signal may be provided to the first coil 2120. The power source or drive signal provided to the first coil 2120 may be a DC signal or an AC signal, or may include a DC signal and an AC signal, and may be in the form of a voltage or a current.

[0799] When a driving signal (e.g., a driving current) is supplied, the first coil 2120 can generate an electromagnetic force through electromagnetic interaction with the first magnet 2130, and the generated electromagnetic force can move the bobbin 2110 in the optical axis (OA) direction.

[0800] From the initial position of the AF movable part, the bobbin 2110 can move in an upward or downward direction, which is called bidirectional drive of the AF movable part.

[0801] Alternatively, the bobbin 2110 can move upward from the initial position of the AF movable part, which is called unidirectional driving of the AF movable part.

[0802] In the initial position of the AF movable part, the first coil 2120 may be arranged to correspond to or overlap with the first magnet 2130 arranged in the housing 2140 in a direction perpendicular to the optical axis (OA) and parallel to a line passing through the optical axis.

[0803] For example, the AF movable part may include a bobbin 2110 and a configuration (e.g., a first coil 2120, a second and a third magnet 2180, 2185) coupled to the bobbin 2110. The AF movable part may further include a lens or a lens barrel coupled to the bobbin 2110.

[0804] Furthermore, the initial position of the AF movable part may be the initial position of the AF movable part when no drive signal or power is applied to the first coil 21120, or it may be a position where the AF movable part is placed by the upper and lower elastic members 2150, 2160 being elastically deformed solely by the weight of the AF movable part.

[0805] In addition, the initial position of the bobbin 2110 may be a position where the AF movable part is placed when gravity acts from the bobbin 2110 to the base 2210, or conversely, when gravity acts from the base 2210 to the bobbin 2110.

[0806] Next, the second and third magnets 2180, 2185 will be described.

[0807] The second magnet 2180 may be referred to as a "sensing magnet" in that it provides a magnetic field for the first position sensor 2170 to sense, and the third magnet 2185 may be referred to as a "balancing magnet" in that it offsets the magnetic field effect of the sensing magnet 2180 and balances the weight with the sensing magnet 2180.

[0808] Each of the second and third magnets 2180, 2185 can be disposed on the bobbin 2110 and can move along the optical axis with the bobbin 2110.

[0809] The second magnet 2180 may be disposed in the seating groove 2180a of the bobbin 2110 and disposed to face the first position sensor 2170. For example, but not limited to, the second magnet 2180 may overlap the first position sensor 2170 in a direction perpendicular to the optical axis and parallel to a line passing through the optical axis at the initial position of the bobbin 2110. In other embodiments, the second magnet 2180 and the first position sensor 2170 may not overlap in a direction perpendicular to the optical axis and parallel to a line passing through the optical axis at the initial position of the bobbin 2110.

[0810] A portion of any one of the surfaces of the second magnet 2180 facing the first position sensor 2170 is exposed from the seating groove 2180a, but this is not limited thereto, and in other embodiments, a portion of any one of the surfaces of the second magnet 2180 facing the first position sensor 2170 may not be exposed from the seating groove 2180a.

[0811] For example, each of the second and third magnets 2180, 2185 can be an anodized magnet including two north poles and two south poles or a four-pole magnet.

[0812] Each of the second and third magnets 2180, 2185 may include a first magnet portion 2017a, a second magnet portion 2017b, and a partition wall 2017c disposed between the first magnet portion 2017a and the second magnet portion 2017b. Here, the partition wall 2017c may be alternatively expressed as a "non-magnetic partition wall."

[0813] The first magnet portion 2017a may include an N pole, an S pole, and a first boundary between the N pole and the S pole. The first boundary may include a section that is substantially non-magnetic and has almost no polarity, and may be a naturally occurring portion that forms a magnet consisting of one N pole and one S pole.

[0814] The second magnet portion 2017b may include an N pole, an S pole, and a second interface between the N pole and the S pole. The second interface may include a section that is substantially non-magnetic and has almost no polarity, and may be a naturally occurring portion that forms a magnet consisting of one N pole and one S pole.

[0815] The partition 2017c may be a portion that separates or isolates the first magnet portion 2017a and the second magnet portion 2017b and has substantially no magnetic property and little polarity. For example, the partition may be a non-magnetic material or air. The non-magnetic partition may be referred to as a "neutral zone" or a "neutral area."

[0816] The partition 2017c is a portion that is artificially formed when magnetizing the first magnet portion 2017a and the second magnet portion 2017b, and the width of the partition 2017c may be greater than the width of the first boundary portion (or the width of the second boundary portion). Here, the width of the partition 2017c may be the length in the direction from the first magnet portion 2017a toward the second magnet portion 2017b. The width of the first boundary portion (or the second boundary portion) may be the length of the first boundary portion in the direction from the north pole to the south pole of each of the first and second magnet portions 2017a, 2017b.

[0817] For example, the first magnet portion 2017a and the second magnet portion 2017b may be disposed to face each other in the optical axis direction. For example, the partition wall 2017c may be perpendicular to the optical axis and parallel to a line passing through the optical axis.

[0818] In another embodiment, each of the second and third magnets may be a monopole magnet having one north pole and one south pole.

[0819] For example, the boundary surface between the north pole and the south pole of each of the second and third magnets 2180, 2185 disposed on the bobbin 2110 may be parallel to a direction perpendicular to the optical axis (OA). For example, the north pole and the south pole of each of the second and third magnets 2180, 2185 may face each other in the optical axis direction.

[0820] For example, the surfaces of the second and third magnets 2180 and 2185 facing the first position sensor 2170 are divided into a north pole and a south pole, but are not limited to this.

[0821] For example, in another embodiment, the second and third magnets 2180, 2185 disposed on the bobbin 2110 may each have an interface between the north and south poles parallel to the optical axis (OA).

[0822] The second magnet 2180 can move in the optical axis direction together with the bobbin 2110, and the first position sensor 2170 can sense the magnetic field strength or magnetic force of the second magnet 2180 moving in the optical axis direction and output an output signal according to the sensed result.

[0823] For example, the strength of the magnetic field or the magnetic force sensed by the first position sensor 2170 may change depending on the displacement of the bobbin 2110 in the optical axis direction, and the first position sensor 2170 may output an output signal proportional to the strength of the sensed magnetic field, and the displacement of the bobbin 2110 in the optical axis direction may be sensed using the output signal of the first position sensor 2170.

[0824] Next, the housing 2140 will be described. The housing 2140 accommodates the bobbin 2110 therein and supports the first magnet 2130, the first position sensor 2170, and the circuit board 2190.

[0825] FIG. 49A shows a perspective view of the housing 2140, circuit board 2190, first position sensor 2170, and capacitor 2195 shown in FIG. 46, and FIG. 49B shows a combined perspective view of the housing 2140, first magnet 2130, circuit board 2190, first position sensor 2170, and capacitor 2195.

[0826] 49A and 49B, the housing 2140 may be generally hollow columnar in shape. For example, the housing 2140 may have a polygonal (e.g., rectangular or octagonal) or circular opening, and the opening of the housing 2140 may be a through hole or a hollow that passes through the housing 2140 in the optical axis direction.

[0827] The housing 2140 may include a number of sides 2141-1 through 2141-4 and corners 2142-1 through 2142-4.

[0828] For example, the housing 2140 may include first to fourth side portions 2141-1 to 2141-4 and first to fourth corner portions 2142-1 to 2142-4 that are spaced apart from one another.

[0829] For example, the first and second sides 2141-1, 2141-2 of the housing 2140 may be located opposite or opposite each other, and the third and fourth sides 2141-3, 2141-4 of the housing 2140 may be located opposite or opposite each other.

[0830] Each of the corner portions 2142-1 to 2142-4 of the housing 2140 can be disposed or positioned between two adjacent side portions 2141-1 and 2141-2, 2141-2 and 2141-3, 2141-3 and 2141-4, or 2141-4 and 2141-1, and can connect the sides 2141-1 to 2141-4 to each other.

[0831] For example, the corner portions 2142-1 to 2142-4 may be located at corners or edges of the housing 2140. For example, the housing 2140 may have four sides and four corners, but is not limited thereto, and may have five or more sides and four corners.

[0832] Each of the side portions 2141-1 to 2141-4 of the housing 2140 can be disposed so as to be parallel to a corresponding one of the side plates 2302 of the cover member 2300.

[0833] For example, the sides 2141-1 to 2141-4 of the housing 2140 may correspond to or face the first side 2110b-1 of the bobbin 2110, and the corners 2142-1 to 2142-4 of the housing 2140 may correspond to or face the second side 2110b-2 of the bobbin 2110.

[0834] The first magnets 2130 may be disposed or installed at the corners 2142-1 to 2142-4 of the housing 2140.

[0835] For example, a seating portion 2141a or a receiving portion for receiving the magnet 2130 may be provided at a corner or at the corner portions 2142-1 to 2142-4 of the housing 2140.

[0836] The seating portion 2141a of the housing 2140 may be provided at the lower portion or the lower end of at least one of the corner portions 2142-1 to 2142-4 of the housing 2140.

[0837] For example, the seating portions 2141a of the housing 2140 may be provided on the lower portion or inside the lower end of each of the four corner portions 2142-1 to 2142-4.

[0838] The seating portion 2141a of the housing 2140 is formed with a groove having a shape corresponding to the first magnet 2130, for example, a concave groove, but is not limited thereto.

[0839] For example, a first opening may be formed on a side of the mounting part 2141a of the housing 2140 facing the first coil 2120, and a second opening may be formed on a bottom surface of the mounting part 2141a of the housing 2140 facing the second coil 2230, in order to facilitate attachment of the first magnet 2130.

[0840] For example, a first surface 2011a of the first magnet 2130 fixed or disposed in the mounting part 2141a of the housing 2140 may be exposed through a first opening of the mounting part 2141a. Also, a lower surface of the first magnet 2130 fixed or disposed in the mounting part 2141a of the housing 2140 may be exposed through a second opening of the mounting part 2141a.

[0841] In order to avoid spatial interference with the first frame connecting portion 2153 of the upper elastic member 2150, the housing 2140 may have escape grooves 2041 provided on the upper surfaces of the corner portions 2142-1 to 2142-4.

[0842] For example, the escape groove 2041 of the housing 2140 may be recessed from the top surface of the housing 2140 and may be located adjacent to the center of the housing 2140 more biased than the stopper 2145 or the adhesive injection hole 2147. For example, the escape groove 2041 may be located on the inside toward the center of the housing 2140 based on the stopper 2145 of the housing 2140, and the adhesive injection holes 2146a, 2146b may be located on the opposite outside.

[0843] The corner portions 2142-1 to 2142-4 of the housing 2140 may be provided with grooves 2025a corresponding to or facing the protrusions 2115 of the bobbin 2110. The grooves 2025a of the housing 2140 may be located on the seating portion 2141a of the housing 2140. For example, the grooves 2025a of the housing 2140 may be formed on a bottom surface of the escape groove 2041. For example, the bottom surface of the grooves 2025a may be located lower than the bottom surface of the escape groove 2041, and the seating groove 2141a of the housing 2140 may be located lower than the bottom surface of the escape groove 2041.

[0844] For example, the bottom surface of the groove portion 2025a of the housing 2140 can be located between the upper surfaces (or upper ends) and lower surfaces (or lower ends) of the buffer po...
