Description

[Technical field]

[0001] The embodiments relate to a lens driving device, and a camera module and an optical device including the lens driving device. [Background technology]

[0002] Camera modules for ultra-compact size and low power consumption have been intensively researched because it is difficult to apply the voice coil motor (VCM) technology used in existing general camera modules.

[0003] The demand and production of electronic products such as smartphones and mobile phones equipped with cameras is increasing. Mobile phone cameras are becoming smaller and higher resolution, and as a result, actuators are becoming smaller, larger in diameter, and more multi-functional. To realize high-resolution mobile phone cameras, there is a demand for improved performance of mobile phone cameras and additional functions such as autofocusing, improved shutter vibration, and zoom functions.

[0004] In addition, in accordance with the trend toward improved functionality and higher pixel counts in mobile phones, the size of image sensors and the diameter of lenses mounted on camera modules are increasing. When vibrations and shocks occur to mobile phones as the diameter of lenses increases, stress on the OIS wires included in the voice coil motors of camera modules increases, causing deformation and breakage of the OIS wires, which can result in the inability to drive the OIS of the camera module and oscillation problems. Summary of the Invention [Problem to be solved by the invention]

[0005] The embodiments provide a lens driving device capable of relaxing or reducing stress on a support member, and a camera module and an optical device including the same. [Means for solving the problem]

[0007] The connecting elastic portion may extend from a corner of the body.

[0008] The base may include a stepped portion including a first surface forming a first step with respect to an upper surface of the base on which the body is disposed, and the connecting elastic portion may be spaced apart from the first surface of the stepped portion and overlap the first surface of the stepped portion in the optical axis direction.

[0009] The step portion may be formed in a corner region of the base, and the base may include a guide portion that protrudes upward from the first surface or in the optical axis direction and surrounds the corner region.

[0010] The circuit board may include a terminal portion extending from the body and including a terminal, and the connecting elastic portion may electrically connect the support member and the terminal.

[0011] A length of the connecting elastic part in the optical axis direction may be smaller than a length of the body in the optical axis direction.

[0012] The connecting portion may include a portion whose width decreases in a direction from the body toward the support member.

[0013] The elastic connecting portion may be a leaf spring. The lens driving device may include a first damper disposed between the elastic connection portion and the body, and connecting the elastic connection portion and the body.

[0030] FIG. 1 is an exploded perspective view of a lens driving device 100 according to an embodiment, and FIG. 2 is an assembled perspective view of the lens driving device 100 without a cover member 300 of FIG.

[0031] 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.

[0032] 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. The circuit board 250 may be referred to as a "first circuit board," and the circuit board 190 may be referred to as a "second circuit board."

[0033] In addition, the lens driving device 100 may further include a second position sensor 240 to achieve a camera shake correction function.

[0034] In addition, the lens driving device 100 may further include a third magnet 185 and a cover member 300.

[0035] In addition, the lens driving device 100 may further include a capacitor 195 mounted on the circuit board 190 .

[0036] First, the bobbin 110 will be described. The bobbin 110 is disposed inside the housing 140 and can move in the direction of the optical axis OA or in a first direction (eg, the Z-axis direction) by electromagnetic interaction between the first coil 120 and the first magnet 130.

[0037] FIG. 3a is 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.

[0038] 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.

[0039] A lens may be directly attached to the opening of the bobbin 110, but is not limited thereto. In another embodiment, 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.

[0040] 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 the same as or less than the latter.

[0041] The bobbin 110 may have a protrusion 115 formed on an outer surface.

[0042] For example, but not limited to, the protrusion 115 may be disposed on the outer surface of the second side 110b2 of the bobbin 110. The protrusion 115 may protrude in a direction parallel to a straight line perpendicular to the optical axis while passing through the center of the opening of the bobbin 110.

[0043] The protrusion 115 of the bobbin 110 corresponds to the groove 25a of the housing 140 and can be inserted or positioned within the groove 25a of the housing 140, thereby suppressing or preventing the bobbin 110 from rotating beyond a certain range around the optical axis.

[0044] 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 in the optical axis direction (e.g., from the upper elastic member 150 toward the lower elastic member 160) more than a specified range due to external impact, etc.

[0045] 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 110b2 of the bobbin 110, but is not limited thereto.

[0046] A guide portion 111 for guiding the mounting 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.

[0047] In addition, a damper (see DA5 in FIG. 11) may be disposed between the guide part 111 and the first frame connecting part 153 of the upper elastic member 150.

[0048] The bobbin 110 may include a stopper 116 protruding from a top surface.

[0049] The stopper 116 of the bobbin 110 can serve to prevent the upper surface of the bobbin 110 from directly colliding with the inside of the upper 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.

[0050] 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, in Fig. 3a, the first coupling portion 113 of the bobbin 110 has a protrusion shape, but is not limited thereto, and in other embodiments, the first coupling portion 113 of the bobbin 110 may have a groove shape or a flat shape.

[0051] 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 has a protrusion shape, but is not limited thereto, and in other embodiments, the second coupling portion of the bobbin 110 may have a groove shape or a flat shape.

[0052] The outer surface of the bobbin 110 may be provided with a seating groove 105 in which the first coil 120 is seated, inserted, or disposed. The seating groove 105 may have a groove structure recessed from the outer surfaces of the first and second sides 110b-1 and 110b-2 of the bobbin 110, and may have a shape that matches the shape of the first coil 120, i.e., a closed curve shape (e.g., a ring shape).

[0053] In addition, in order to prevent the coil 120 from coming off and to guide both ends of the coil 120 when the coil 120 is connected to the lower elastic members 160-1 and 160-2, two of the sides 110b-1 and 110b-2 of the bobbin 110 may be provided with guide grooves 116a and 116b. For example, the guide grooves 116a and 116b may be provided on the lower surfaces of the two first sides 110b-1 or the two second sides 110b-2 located on opposite sides of the bobbin 110.

[0054] In addition, the outer surface of the bobbin 110 may be provided with a seating groove 180a in which the second magnet 180 is seated, inserted, fixed, or disposed.

[0055] 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 that is open to at least one of the upper surface or the lower surface of the bobbin 110, but is not limited thereto.

[0056] In addition, the bobbin 110 may have a seating groove 185a on an outer surface thereof in which the third magnet 185 is seated, inserted, fixed, or disposed.

[0057] 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 that is open to at least one of the upper surface or the lower surface of the bobbin 110, but is not limited thereto.

[0058] 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 to 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.

[0059] 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.

[0060] For example, the seating grooves 180a, 185a may be disposed on two opposing first sides of the bobbin 110 or on two opposing first sides.

[0061] Since the second magnet 180 and the third magnet 185 are disposed in seating grooves 180a, 185a provided on two first sides located on opposite sides of the bobbin 110, the weight of the second magnet 180 and the third magnet 185 can be balanced, and the influence of the AF driving force due to magnetic field interference between the first magnet 130 and the second magnet 180 and the influence of the AF driving force due to magnetic field interference between the first magnet 130 and the third magnet 185 can be offset each other, thereby improving the accuracy of AF (Auto Focusing) driving in this embodiment.

[0062] The bobbin 110 may have a thread 11 on its inner circumferential surface for coupling with a lens or a lens barrel. The thread 11 may be formed on the inner circumferential surface of the bobbin 110 while the bobbin 110 is fixed by a jig or the like, and the bobbin 110 may have jig fixing grooves 15a, 15b on its upper surface. For example, the jig fixing grooves 15a, 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, 15b may also function as a foreign matter collector for collecting foreign matter.

[0063] Next, the first coil 120 will be described. The first coil 120 is disposed on the bobbin 110. For example, the first coil 120 may be disposed on an outer surface of the bobbin 110. For example, the first coil 120 may move together with the bobbin 110 in the optical axis direction.

[0064] The first coil 120 may be disposed below the second and third magnets 180 and 185, but is not limited thereto. For example, the first coil 120 may be disposed below the protruding portion 115 of the bobbin 110, but is not limited thereto.

[0065] For example, the first coil 120 may not overlap the second and third magnets 180, 185 in a direction perpendicular to the optical axis, but is not limited thereto. 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.

[0066] For example, the first coil 120 may be disposed within the seating groove 105 of the bobbin 110, the second magnet 180 may be inserted or disposed within the seating groove 180a of the bobbin 110, and the third magnet 185 may be inserted or disposed within the seating groove 185a of the bobbin 110. The first and second magnets 180, 185 may be disposed inside the first coil 120.

[0067] Each of the second magnet 180 and the third magnet 185 arranged on the bobbin 110 may be spaced apart from the first coil 120 in the direction of the optical axis OA, 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.

[0068] The first coil 120 may surround the outer surface of the bobbin 110 in a direction rotating about 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.

[0069] 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 a polygonal ring-shaped coil block.

[0070] 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 have a form of voltage or current.

[0071] When a driving signal (e.g., a driving current) is supplied to the first coil 120, an electromagnetic force can be generated through electromagnetic interaction with the first magnet 130, and the bobbin 110 can move in the direction of the optical axis OA due to the generated electromagnetic force.

[0072] In the initial position of the AF actuator, the bobbin 110 can move upward or downward, which is called bidirectional driving of the AF actuator.

[0073] Or, at the initial position of the AF operating part, the bobbin 110 can move upward, which is called unidirectional driving of the AF operating part.

[0074] In the initial position of the AF operating unit, the first coil 120 may be disposed to correspond to or overlap with the first magnet 130 disposed in the housing 140 in a direction perpendicular to the optical axis OA and parallel to a line passing through the optical axis.

[0075] For example, the AF operating unit may include a bobbin 110 and components (e.g., the first coil 120, the second and third magnets 180, 185) coupled to the bobbin 110. The AF operating unit may further include a lens or lens barrel coupled to the bobbin 110.

[0076] The initial position of the AF operating part may be the initial position of the AF operating part when no power is applied to the first coil 1120, or the position where the AF operating part is placed as the upper and lower elastic members 150, 160 are elastically deformed solely by the weight of the AF operating part.

[0077] In addition, the initial position of the bobbin 110 may be a position where the AF operating part is located when gravity acts in a direction from the bobbin 110 to the base 210, or conversely, when gravity acts in a direction from the base 210 to the bobbin 110.

[0078] Next, the second and third magnets 180, 185 will be described.

[0079] The second magnet 180 can 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 can 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.

[0080] 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, at the initial position of the bobbin 110, 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, but is not limited to this. In other embodiments, at the initial position of the bobbin 110, 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.

[0081] A portion of any one surface of the second magnet 180 facing the first position sensor 170 may be exposed from the seating groove 180a, but this is not limited to this, and in other embodiments, a portion of any one surface of the second magnet 180 facing the first position sensor 170 may not be exposed from the seating groove 180a.

[0082] 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.

[0083] Each of the second and third magnets 180 and 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 be alternatively expressed as a "non-magnetic partition wall."

[0084] 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.

[0085] 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 is a portion that is substantially non-magnetic and may include a section that has almost no polarity, and may be a naturally occurring portion that forms a magnet consisting of one N pole and one S pole.

[0086] The partition 17c separates or isolates the first magnet portion 17a and the second magnet portion 17b, and may be a portion 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 expressed as a "neutral zone" or a "neutral area."

[0087] 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 N pole to the S pole of each of the first and second magnet portions 17a and 17b.

[0088] 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 is perpendicular to the optical axis.

[0089] In another embodiment, each of the second and third magnets can be a monopole magnet having one north pole and one south pole.

[0090] For example, the boundary surface between the N pole and the S pole of each of the second and third magnets 180, 185 arranged on the bobbin 110 may be parallel to a direction perpendicular to the optical axis OA. For example, the N pole and the S pole of each of the second and third magnets 180, 185 may face each other in the optical axis direction.

[0091] For example, the surfaces of the second and third magnets 180 and 185 facing the first position sensor 170 may be divided into a north pole and a south pole, but are not limited thereto.

[0092] 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.

[0093] 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 based on the sensed result.

[0094] For example, the magnetic field strength or magnetic force sensed by the first position sensor 170 may change depending on 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.

[0095] 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 .

[0096] 4a is 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 is 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.

[0097] 4a and 4b, the housing 140 may have an overall hollow columnar shape. 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 have a through-hole shape penetrating the housing 140 in the optical axis direction.

[0098] The housing 140 may include a number of side portions 141-1 to 141-4 and corner portions 142-1 to 142-4.

[0099] 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.

[0100] 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.

[0101] Each of the corner portions 142-1 to 142-4 of the housing 140 may be disposed or located between two adjacent sides 141-1 and 141-2, 141-2 and 141-3, 141-3 and 141-4, or 141-4 and 141-1, and the sides 141-1 to 141-4 may be connected to each other.

[0102] For example, the corner portions 142-1 to 142-4 may be located at corners or edge portions of the housing 140. For example, the housing 140 has four sides and four corner portions, but is not limited thereto and may have five or more sides and four corner portions.

[0103] Each of the side portions 141 - 1 to 141 - 4 of the housing 140 may be disposed parallel to a corresponding one of the side plates 302 of the cover member 300 .

[0104] For example, the sides 141-1 to 141-4 of the housing 140 may correspond to or face the first side 110b1 of the bobbin 110, and the corners 142-1 to 142-4 of the housing 140 may correspond to or face the second side 110b2 of the bobbin 110.

[0105] The first magnets 130 may be disposed or attached to the corners 142-1 to 142-4 of the housing 140.

[0106] For example, a seating portion 141a or a receiving portion for receiving the magnet 130 may be provided at the corners or corner portions 142-1 to 142-4 of the housing 140.

[0107] The seating portion 141a of the housing 140 may be provided at a lower portion or a lower end of at least one of the corner portions 142-1 to 142-4 of the housing 140.

[0108] For example, the seating portions 141a of the housing 140 may be provided on the lower portions or inside the lower ends of the four corner portions 142-1 to 142-4.

[0109] The seating portion 141a of the housing 140 may be formed as a groove having a shape corresponding to the first magnet 130, for example, a concave groove, but is not limited thereto.

[0110] For example, a first opening may be formed on a side of the seating portion 141a of the housing 140 facing the first coil 120, and a second opening may be formed on a bottom surface of the seating portion 141a of the housing 140 facing the second coil 230, to facilitate attachment of the first magnet 130.

[0111] For example, the first surface 11a of the first magnet 130 fixed or disposed on the seating portion 141a of the housing 140 may be exposed through a first opening of the seating portion 141a. Also, the lower surface of the first magnet 130 fixed or disposed on the seating portion 141a of the housing 140 may be exposed through a second opening of the seating portion 141a.

[0112] In order to avoid spatial interference with the first frame connecting portion 153 of the upper elastic member 150, the housing 140 may have escape grooves 41 formed on the upper surfaces of the corner portions 142-1 to 142-4.

[0113] For example, the escape groove 41 of the housing 140 may have a shape 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 holes 146a, 146b. 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.

[0114] 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.

[0115] The first magnet 130 may be fixed to the seat 141a by an adhesive, but is not limited thereto.

[0116] 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 have a recessed shape from the upper surface of the corners 142-1 to 142-4.

[0117] 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, and thus the fixing force between the first magnet 130 and the housing 140 may be improved.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] In order to easily mount the circuit board 190, the mounting groove 14a of the housing 140 may have a groove shape with an open top, 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.

[0123] 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.

[0124] 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 them adjacent to each other, thereby reducing noise due to an increase in the path.

[0125] The capacitor 195 may be disposed or mounted on the first surface 19 b of the circuit board 190 .

[0126] The capacitor 195 may have a chip type. Here, 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 alternatively referred to as a "capacitive element" or a "condenser".

[0127] In another embodiment, the capacitor may be embodied as being included in the circuit board 190. For example, the 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 conductive layer and the second conductive layer.

[0128] The capacitor 195 may be electrically connected in parallel to two terminals (eg, B1 and B2) of the circuit board 190 for providing power (or a driving signal) to the position sensor 170 from the outside.

[0129] 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 .

[0130] 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.

[0131] The capacitor 195 is electrically connected in parallel to the first and second terminals B1 and B2 of the circuit board 190, and can thus act as a smoothing circuit to remove ripple components contained in the power signals GND and 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.

[0132] The capacitor 195 is electrically connected in parallel to the first and second terminals B1 and B2 of the circuit board 190, thereby protecting the first position sensor 170 from high-frequency noise or ESD that may flow in from the outside.

[0133] 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 by the output signal of the first position sensor 170 from being reset due to the overcurrent.

[0134] In addition, for easy installation of the first position sensor 170, the mounting groove 14b of the housing 140 may be open at the top, and for increasing sensing sensitivity, the mounting groove 14b may have an opening that opens to the 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.

[0135] 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 adhesive tape.

[0136] At the corners 142-1 to 142-4 of the housing 140, support members 220-1 to 220-4 may be disposed.

[0137] Holes 147 forming paths through which the support members 220-1 to 220-4 pass may be provided in the corners 142-1 to 142-4 of the housing 140. For example, the housing 140 may include holes 147 penetrating upper portions of the corners 142-1 to 142-4. The number of holes 147 in the housing 140 may be the same as the number of the support members.

[0138] In another embodiment, an escape structure may be provided to avoid spatial interference with the support members 220-1 to 220-4. For example, the housing in another embodiment may have an escape structure in which the outer surface of the corner portion is recessed or at least a portion of the hole 147 is open.

[0139] 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.

[0140] 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.

[0141] In order to form paths through which the support members 220-1 to 220-4 pass and 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 semicircular or semi-elliptical shape, but are not limited thereto. A lower portion or a lower end of the escape groove 148a may be connected to the lower surface of the housing 140.

[0142] For example, the diameter of the escape groove 148a may be gradually decreased from the top to the bottom, but is not limited thereto.

[0143] 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.

[0144] For example, the stoppers 145 may be disposed on the upper surfaces of the corners 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.

[0145] In addition, a stopper (not shown) may be provided on the lower portion, bottom end, or bottom surface of the housing 140 to prevent the bottom surface of the housing 140 from colliding with the base 210 and / or the circuit board 250.

[0146] In addition, the corners of the upper surface of the corner portions 142-1 to 142-4 of the housing 140 may be provided with guide protrusions 146 to prevent the dampers from overflowing.

[0147] For example, the hole 147 of the housing 140 may be located between the corners (eg, the guide protrusions 146 ) of the upper surfaces of the corner portions 142 - 1 to 142 - 4 of the housing 140 and the stoppers 145 .

[0148] At least one first coupling portion 143 coupled to a first outer frame 152 of the upper elastic member 150 may be provided on the upper portion, upper end, or upper surface of the housing 140 .

[0149] 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.

[0150] 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 .

[0151] For example, each of the first and second coupling portions 143, 149 of the housing 140 may have a protrusion shape, but is not limited thereto, and may have a groove shape or a flat shape in other embodiments.

[0152] 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 may 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 may be connected.

[0153] 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.

[0154] 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.

[0155] In the initial position of the AF operating unit, the first magnet 130 may be disposed in the housing 140 such that the first magnet 130 at least partially overlaps with the first coil 120 in a direction perpendicular to the optical axis OA and parallel to a line passing through the optical axis OA.

[0156] For example, the first magnet 130 may be inserted or disposed within a corresponding one of the seating portions 141a among the corner portions 141-1 to 141-4 of the housing 140.

[0157] In another embodiment, the first magnet 130 may be disposed on the outer surfaces of the corners 141-1 to 141-4 of the housing 140.

[0158] The first magnet 130 may have a polyhedral shape that is easy to seat on the corner portion of the housing 140.

[0159] 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 side of the first coil 120 (or the outer surface of the bobbin 110), and the second surface 11b may be a surface opposite to the first surface 11a.

[0160] For example, the length of the second surface 11b of the first magnet 130 in the lateral direction may be smaller than the length of the first surface 11a in the lateral direction.

[0161] 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.

[0162] 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.

[0163] 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.

[0164] For example, the first magnet 130 may include a portion whose length in the lateral direction of the first magnet 130 decreases in the direction from the first surface 11a to 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.

[0165] The first magnet 130 may include a plurality of magnets 130-1 to 130-4 disposed in a housing 140.

[0166] 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 a limitation, 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.

[0167] The first magnets may be disposed or attached to the corners of the housing 140 such that at least two of the first magnets face each other.

[0168] For example, two pairs of magnets 130-1 and 130-3, and 130-2 and 130-4 facing each other to intersect with each other may be disposed at corner portions 142-1 to 142-4 of the housing 140. Here, the horizontal planar shape of each of the plurality of magnets 130-1 to 130-4 may be a polygon such as a triangle, a pentagon, a hexagon, or a rhombus.

[0169] In other embodiments, opposing pairs of magnets may be disposed only at two opposing corners of the housing 140 .

[0170] In another embodiment, the magnet may be disposed on a side of the housing 140 instead of a corner of the housing 140, and the circuit board 190, the first position sensor 170, and the capacitor 195 may be disposed at one of the corners of the housing 140, and the sensing magnet may be disposed on the outer surface of the bobbin 110 corresponding to the first position sensor 170. Also, for example, in another embodiment, a plurality of magnets may be disposed on the side of the housing 140, and each of the magnets may have a polyhedral shape suitable for being disposed on the side of the housing, for example, a cube or a rectangular parallelepiped shape, but is not limited thereto.

[0171] 5 is a cross-sectional view of the lens driving device 100 shown in FIG. 2 taken along the AB direction, and FIG. 6 is a cross-sectional view of the lens driving device 100 shown in FIG. 2 taken along the CD direction.

[0172] 5 and 6, the second and third magnets 180, 185 may not overlap 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 this is not limited thereto. In other embodiments, the second and third magnets 180, 185 may overlap the first coil 120.

[0173] In addition, in the initial position of the AF operating unit, the second magnet 180 may overlap or be 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. In other embodiments, the two may not overlap each other.

[0174] In addition, in the initial position of the AF operating unit, the first position sensor 170 may overlap 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 another embodiment, the first position sensor 170 may not overlap with at least one of the second and third magnets 180, 185.

[0175] Also, the first position sensor 170 may not overlap with the first magnet 130 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.

[0176] 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.

[0177] Next, the circuit board 190 and the first position sensor 170 will be described.

[0178] The circuit board 190 may be disposed in or coupled to the housing 140 .

[0179] 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.

[0180] 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.

[0181] For example, the circuit board 190 may not overlap an imaginary line connecting a corner portion (e.g., a 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.

[0182] FIG. 7a is an enlarged view of the circuit board 190 and the first position sensor 170, and FIG. 7b is a diagram showing an embodiment of the first position sensor 170 shown in FIG. 7a.

[0183] 7a and 7b, a circuit board 190 may include terminals B1 to B6 for electrically connecting to an external terminal or an external device.

[0184] The first position sensor 170 may be disposed on the first surface 19b of the circuit board 190, and the terminals B1 to B6 may be disposed on the second surface 19a of the circuit board 190, but are not limited thereto.

[0185] In another embodiment, the first position sensor 170 and the terminals B1 to B6 may be disposed on either the first or second surface of the circuit board 180. In yet another embodiment, the first position sensor 170 may be disposed on either the first or second surface of the circuit board 180, and the terminals B1 to B6 may be disposed on the other surface of the circuit board 180.

[0186] 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.

[0187] The circuit board 190 may include a body portion S1 and an extension portion S2 located below the body portion S1. The body portion S1 may be alternatively expressed as an "upper end portion," and the extension portion S2 may be alternatively expressed as a "lower end portion."

[0188] An extension S2 may extend downwardly from the body portion S1. The body portion S1 may have a shape that protrudes based on the side surfaces 16a and 16b of the extension portion S2. For example, the side surfaces 16a and 16b of the extension portion S2 may be surfaces that connect the first surface 19b of the extension portion S2 and the second surface 19a of the extension portion S2.

[0189] The 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.

[0190] 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.

[0191] 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.

[0192] For example, the lateral length of the body portion S1 of the circuit board 190 may be greater than the lateral length of the extension portion S2.

[0193] For example, the first to fourth terminals B1 to B4 of the circuit board 190 may be spaced apart from each other on the second surface 19a of the 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.

[0194] 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.

[0195] For example, the first terminal B1 of the circuit board 190 may be arranged at one end of the circuit board 190 (e.g., one end of the upper end), the second terminal B1 may be arranged at the other end of the circuit board 190, the third terminal B3 may be arranged between the first terminal B1 and the second terminal B2, and the fourth terminal B4 may be arranged between the third terminal B3 and the first terminal B1.

[0196] The first terminal B1 of the circuit board 190 may be disposed in a first extension area A1 of the body portion S1 of the circuit board 190, and the second terminal B2 may be disposed in a second extension area A2 of the body portion S1 of the circuit board 190.

[0197] The first to fourth terminals B1 to B4 may be disposed so as to be located closer to the upper surface 19c of the circuit board 190 than to the lower surface thereof.

[0198] For example, the first to fourth terminals B1 to B4 may be formed to contact the second surface 19a and the upper surface 19c of the body portion S1 of the circuit board 190 adjacent to the second surface 19a.

[0199] 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, for example.

[0200] 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.

[0201] Such grooves 7a increase the contact area between the solder and the terminals B3, B4, thereby improving adhesive strength and solderability.

[0202] 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.

[0203] The circuit board 190 may have a groove 8a or a hole between the fifth terminal B5 and the sixth terminal B6. The groove 8a may have a recessed shape from the bottom surface of the circuit board 190 and may be open on both the first surface 19b and the second surface 19a of the circuit board 190.

[0204] 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, and 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.

[0205] Also, 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.

[0206] For example, the fifth terminal B5 and the sixth terminal B6 may include a curved portion recessed from the bottom surface of the circuit board 190, such as a semicircular via or groove.

[0207] The grooves 7b increase the contact area between the solder and the fifth and sixth terminals B5, B6, thereby improving adhesive strength and solderability.

[0208] 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."

[0209] Each of the first groove 90a and the second groove 90b may have a shape recessed from the upper surface 19c of the circuit board 190 and may be open on both the first surface 19b and the second surface 19a of the circuit board 190.

[0210] The first groove 90a of the circuit board 190 may 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 may be formed to avoid spatial interference with the first outer frame 151 of the fourth upper elastic unit 150-4.

[0211] For example, the circuit board 190 can be a printed circuit board or FPCB.

[0212] 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.

[0213] 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 according to the movement of the bobbin 110, and can output an output signal according to the sensed result.

[0214] 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 a mounting groove 14b of the housing 190 and may move together with the housing 140 during image stabilization.

[0215] The first position sensor 170 may be disposed on the first surface 19b of the circuit board 190. In another embodiment, the first position sensor 170 may be disposed on the second surface 19a of the circuit board 190.

[0216] The first position sensor 170 is a Hall sensor. 1061 , and Driver 1062 may include.

[0217] For example, Hall sensors 1061 The Hall sensor can be made of silicon, and the more the ambient temperature increases, the 1061 The output VH of the lens driver can be increased. For example, the ambient temperature can be increased by increasing the temperature of the lens driver, such as the temperature of the circuit board 190, the Hall sensor 1061 Temperature or driver 1062 The temperature can be.

[0218] In another embodiment, a Hall sensor 1061 The Hall sensor can be made of GaAs and can be switched on and off depending on the ambient temperature. 1061 The output VH of the Hall sensor can be decreased. 1061 The output of the may have a slope of about -0.06% / °C with respect to ambient temperature.

[0219] The first position sensor 170 is a temperature sensing element capable of sensing the ambient temperature. 1063 The temperature sensing element may further include: 1063 The temperature detection signal Ts based on the result of measuring the ambient temperature of the first position sensor 170 is output to the driver. 1062 can be output to.

[0220] For example, the first position sensor 190 is a Hall sensor. 1061may 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 190 may be proportional to the strength of the magnetic force of the second magnet 180.

[0221] driver 1062 Hall sensor 1061 and a drive signal Id1 for driving the first coil 120.

[0222] For example, data communication using a protocol, such as I2C communication, 1062 can receive a clock signal SCL, a data signal SDA, and power signals VDD and GND from the control units 830 and 780.

[0223] Here, the second power supply signal VDD is the driver 1062 The first power signal GND may be a ground voltage or 0V, but is not limited thereto, and in other embodiments, may be a voltage lower than the second power signal. For example, the first and second power signals may be DC voltages and / or AC voltages, but is not limited thereto.

[0224] driver 1062 The Hall sensor is driven by the clock signal SCL and the power supply signals VDD and GND. 1061 and a drive signal Id1 for driving the first coil 120.

[0225] The first position sensor 170 may include four terminals for transmitting and receiving a clock signal SCL, a data signal SDA, and power signals VDD and GND, and two terminals for providing a driving signal to the first coil 120.

[0226] Also, the driver 1062 Hall sensor 1061 The output VH of the Hall sensor is received, and data communication using a protocol, for example, I2C communication, is used. 1061 The clock signal SCL and the data signal SDA for the output VH can be transmitted to the control units 830 and 780.

[0227] Also, the driver 1062 is a temperature sensing element 1063 and transmits the temperature sensing signal Ts to the control unit 830, 780 using data communication using a protocol, for example, I2C communication.

[0228] The control unit 830 and 780 controls the temperature sensing element of the first position sensor 170. 1063 Based on the ambient temperature change measured by the Hall sensor 1061 It is possible to perform temperature compensation for the output VH of the inverter.

[0229] For example, Hall sensors 1061 When the drive signal dV or the bias signal is 1 [mA], the Hall sensor of the first position sensor 170 1061 The output VH can be in the range of -20 [mV] to +20 [mV], but is not limited to this.

[0230] And the Hall sensor has a negative slope with respect to the ambient temperature change. 1061 In the case of temperature compensation for the output VH of the first position sensor 170, the Hall sensor 1061 The output VH can be in the range of 0 [mV] to +30 [mV], but is not limited to this.

[0231] 1st position sensor 170 Hall sensor 1061 When the output of the Hall sensor of the first position sensor 170 is displayed in the xy coordinate system,1061 The reason for setting the output range to the first quadrant (e.g., 0 [mV] to +30 [mV]) is as follows.

[0232] The Hall effect of the first quadrant of the xy coordinate system changes with the ambient temperature. 1061 Output of the Hall sensor in the third quadrant 1061 Since the outputs of the first and third quadrants move in opposite directions, the accuracy and reliability of the Hall sensor may be reduced if both the first and third quadrants are used as AF drive control sections. Therefore, in order to accurately compensate for changes in ambient temperature, a certain range of the first quadrant is set to the Hall sensor of the first position sensor 170. 1061 The output range can be:

[0233] The first position sensor 170 may include first to fourth terminals for two power supply signals VDD, GND, a clock signal SCL, and a data signal SDA, and fifth and sixth terminals for providing a driving signal to the first coil 120.

[0234] 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.

[0235] In another embodiment, the first position sensor 170 may be implemented as a single position detection sensor such as a Hall sensor, etc. In this case, the first position sensor 170 may include two input terminals to which a power signal is input and two output terminals to which an output signal is output, and a driving signal may be provided to the first coil 120 from the outside via the circuit board 250.

[0236] The first to fourth terminals B1 to B4 of the circuit board 190 may be electrically connected to terminals 251-1 to 251-n (n is a natural number greater than 1, n>1) of the circuit board 250 by the upper elastic units 150-1 to 150-4 and the support members 220-1 to 220-4, thereby allowing the first position sensor 170 to be electrically connected to terminals 251-1 to 251-n (e.g., n=4) of the circuit board 250.

[0237] For example, each of the upper elastic units 150-1 to 150-4 may be directly coupled and electrically connected to a corresponding one of the first to fourth terminals of the circuit board 180. Also, one end of each of the support members 220-1 to 220-4 may be directly coupled to a corresponding one of the upper elastic units 150-1 to 150-4 by a conductive adhesive member such as solder, and the other end of each of the support members 220-1 to 220-4 may be directly coupled to the circuit board 250.

[0238] 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.

[0239] 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.

[0240] In the lens driving device 100, the first position sensor 170 is disposed in the housing 140 and the second magnet 180 is disposed in the bobbin 110, but in other embodiments, the first position sensor may be disposed in the bobbin and the second magnet may be disposed in the housing. In this case, the circuit board may be disposed in the bobbin and the third magnet may be disposed in the housing.

[0241] Next, the upper elastic member 150, the lower elastic member 160, and the support member 220 will be described.

[0245] The upper elastic member 150 and the lower elastic member 160 can elastically support the bobbin 110 with respect to the housing 140 .

[0246] 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 .

[0247] 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 shown in FIG. 10, the number of the upper elastic units is not limited thereto, and may be three or more in other embodiments.

[0248] 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.

[0249] 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.

[0250] 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 .

[0251] For example, each of the first to fourth upper elastic units 150-1 to 150-4 may be disposed at a corresponding one of the corner portions of the housing 140 and may include a first outer frame 152 coupled to the corresponding one of the corner portions of the housing 140.

[0252] 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.

[0253] In the embodiment of FIG. 8, each of the first and second upper elastic units 150-1, 150-2 may have only a first outer frame and may not have a first inner frame and a first frame connecting portion, and each of the first and second upper elastic units 150-1, 150-2 may be separated from the bobbin 110.

[0254] Each of the third and fourth upper elastic units 150-3 and 150-4 may include a first inner frame 151, a first outer frame, and a first frame connecting portion 153, but is not limited thereto.

[0255] For example, the first inner frame 151 of the third and fourth upper elastic units 150-3 and 150-4 may have a hole 151a for being coupled to the first coupling portion 113 of the bobbin 110, but is not limited thereto. 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.

[0256] 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.

[0257] The first outer frame 151 of each of the first to fourth upper elastic units 150-1 to 150-4 may include a 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 expressed as "extensions". For example, the support member 220 may be coupled to the body portion of the first outer frame 151.

[0258] Each of the first outer frames 151 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 first connecting portion 520 and extending to the first side portion 141-1 of the housing 140.

[0259] For example, the "body portion" of each of the first to fourth upper elastic units 150-1 to 150-4 may be or include the first connecting portion 520. Also, for example, the "body portion" of each of the first to fourth upper elastic units 150-1 to 150-4 may further include at least one of the second connecting portion 510 and the connecting portion 530.

[0260] For example, by means of solder or a conductive adhesive, one end of the first support member 220-1 may be coupled to the second coupling portion 510 of the first upper elastic unit 150-1, one end of the second support member 220-2 may be coupled to the second coupling portion 510 of the second upper elastic unit 150-1, one end of the third support member 220-3 may be coupled to the second coupling portion 510 of the third upper elastic unit 150-3, and one end of the fourth support member 220-4 may be coupled to the second coupling portion 510 of the fourth upper elastic unit 150-4.

[0261] The second coupling part 510 may have holes 52 through which the supporting members 220-1 to 220-4 pass. One ends of the supporting 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 supporting members 220-1 to 220-4 may be electrically connected.

[0262] 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.

[0263] 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).

[0264] 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 .

[0265] 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 have one or more first coupling portions corresponding thereto.

[0266] For example, in order to support the housing 140 evenly without leaning to one side, the coupling regions 5a, 5b of the first coupling 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 thereto.

[0267] In addition, the first coupling portions 143 of the housing 140 may be symmetrical with respect to a reference line (e.g., 501, 502), and two may be provided on each side of the reference line, but the number is not limited thereto.

[0268] The reference lines 501 and 502 may be straight lines passing through the center point 101 and any one 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 that face each other in a diagonal direction of the housing 140 among the corner portions 142-1 to 142-4 of the housing 140.

[0269] Here, the center point 101 can 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 can be the spatial center of the structure 140, 110, or 150.

[0270] Also, for example, the corners of the housing 140 may be aligned or correspond to the center of the corners of the housing 140 .

[0271] In the embodiment of FIG. 8, each of the coupling regions 5a, 5b of the first coupling portion 520 of the first outer frame 152 is embodied to include a hole 152a, but this is not limited thereto, and in other embodiments, the coupling regions may be embodied in various shapes sufficient to couple with the housing 140, such as a groove shape.

[0272] For example, the hole 152a of the first coupling portion 520 may have at least one cutout 52a for allowing an adhesive material to penetrate between the first coupling portion 143 of the housing 140 and the hole 152a.

[0273] The connecting part 530 may connect the second connecting part 510 and the first connecting part 520 to each other.

[0274] For example, the connecting part 530 may connect the connecting regions 5 a , 5 b of the second connecting part 510 and the first connecting part 520 .

[0275] 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.

[0276] 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.

[0277] 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 in other embodiments, may have a straight line shape.

[0278] The width of the connecting portion 530 may be smaller than the width of the first coupling portion 520. Also, the width of the connecting portion 530 may be smaller than the width (or diameter) of the first coupling portion. In other embodiments, the width of the connecting portion 530 may be the same as the width of the first coupling portion 520, or may be the same as the width (or diameter) of the first coupling portion.

[0279] For example, the first coupling part 520 may come into contact with the upper surfaces of the corner parts 142-1 to 142-4 of the housing 140 and may be supported by the corner parts 142-1 to 142-4 of the housing 140. For example, the connecting part 530 may not be supported by the upper surface of the housing 140 and may be spaced apart from the housing 140. Also, in order to prevent oscillation due to vibration, a damper (see DA3 in FIG. 11) may be filled in the space between the connecting part 530 and the housing 140.

[0280] The width of each of the first and second connecting parts 530a, 530b may be smaller than the width of the first joining part 520, thereby allowing the connecting part 530 to move easily in the first direction, 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.

[0281] 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.

[0282] 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.

[0283] 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 second side portion 141-2 and the first corner portion 142-1 of the housing 140.

[0284] 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.

[0285] 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 solder or a conductive adhesive member.

[0286] Each of the first and second extensions P1 and P2 may have a straight line shape, but is not limited thereto, and in other embodiments may include a bent or curved portion.

[0287] For easy 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 a bent or curved portion.

[0288] The first outer frame of the third upper elastic unit 150-3 is connected between the first connecting portion 520 and the extension portion P3, and may further include a first extension frame 154-1 located at the fourth side portion 141-4 and the fourth corner portion 142-4 of the housing 140.

[0289] In order to strengthen the bonding force with the housing 140 and prevent the third upper elastic unit 150-3 from floating up, 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 areas 6a, 6b may have holes for bonding to the first bonding portion 143 of the housing 140.

[0290] The first outer frame of the fourth upper elastic unit 150-4 is connected between the first connecting portion 520 and the extension portion P4, and may further include a second extension frame 154-2 located at the second side portion 141-2 and the first corner portion 142-1 of the housing 140.

[0291] In order to strengthen the bonding force with the housing 140 and prevent the fourth upper elastic unit 150-4 from floating up, 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 areas 6c, 6d may have holes for bonding to the first bonding portion 143 of the housing 140.

[0292] 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.

[0294] Since the four terminals B1 to B4 provided on the 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 each of the first outer frames 151 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.

[0295] 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.

[0296] Referring to FIG. 11, each extension portion P1 to P4 of the upper elastic units 150-1 to 150-4 can be directly coupled to a corresponding one of four terminals B1 to B4 provided on the body portion S1 of the circuit board 190 by a conductive adhesive member 71 such as solder or conductive epoxy.

[0299] 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 a portion of the fourth upper elastic unit 150-4 may be coupled to the fourth terminal B4 of the circuit board 190.

[0300] The third extension portion P3 of the third upper elastic unit 150-3 may pass through the first groove 90a of the circuit board 190 and extend toward the third terminal B3 of the circuit board 190, and may be bent at least twice.

[0301] 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 may be bent at least twice.

[0302] 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 and 2b.

[0303] 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”) bent at the first portion 1a, a second portion 1b extending from the first bending region 2a, a second bending region 2b (or a “second bending portion”) bent at the second portion 1b, and a third portion 1c extending from the second bending region 2b toward the third terminal B3.

[0304] For example, the second portion 1b of the third extension portion P3 (or the third connecting terminal) may be bent from the first portion 1a, and the third portion 1c may be bent from the second portion 1b.

[0305] The second portion 1b of the third extension portion P3 is disposed between the first folding region 2a and the second folding region 2b, and can connect the first and second folding regions 2a, 2b.

[0306] For example, the first portion 1a and the third portion 1c of the third extension portion P3 may each extend in a direction from the second corner portion 142-2 toward the first corner portion 141-1 of the housing 140. For example, the second portion 1b of the third extension portion P3 may extend in a direction from the inner surface of the housing 140 toward the outer surface.

[0307] A part of the third extension portion P3 of the third upper elastic unit 150-3 (eg, the second portion 1b) may be positioned within the first groove 90a of the circuit board 190 or may pass through the first groove 90a.

[0308] 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.

[0309] 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”) bent 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”) bent 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.

[0310] For example, the fifth portion 1e of the fourth extension portion P4 (or the fourth connecting terminal) may be bent at the fourth portion 1d, and the sixth portion 1f may be bent at the fifth portion 1e.

[0311] The fifth portion 1e of the fourth extension portion P4 is disposed between the third bending region 2c and the fourth bending region 2d, and can connect the third and fourth bending regions 2c and 2d.

[0312] For example, the fourth portion 1d and the sixth portion 1f of the fourth extension portion P4 may each extend in a direction from the first corner portion 142-1 to 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.

[0313] A part of the fourth extension portion P4 of the fourth upper elastic unit 150-4 (eg, the fifth portion 1e) may be positioned within the second groove 90b of the circuit board 190 or may pass through the second groove 90b.

[0314] Referring to FIG. 9, the lower elastic member 160 may include a plurality of lower elastic units 160-1, 160-2.

[0316] The second inner frame 161 may be provided with a hole 161a for being coupled 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 being coupled to the second coupling portion 149 of the housing 140.

[0317] 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 portions 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 portions.

[0318] Each of the first and second lower elastic units 160-1 and 160-2 may include connection frames 164-1 to 164-4 that connect the second outer frames 162-1 to 162-3 to each other.

[0319] The width of each of the connecting frames 164-1 to 164-4 may be smaller than the width of each of the second outer frames 162-1 to 162-3, but is not limited to this.

[0320] The connection frames 164-1 to 164-4 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. Here, 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.

[0321] Also, for example, the connecting frames 164-1 to 164-4 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 to this, and in other embodiments, at least a portion of the connecting frames 164-1 to 164-4 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.

[0322] The upper elastic units 150-1 to 150-4 and the lower elastic units 160-1 and 160-2 may be formed of leaf springs, but are not limited thereto and may be formed of 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.

[0323] 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.

[0324] Each of the support members 220-1 to 220-4 may be coupled to a corresponding one of the first to fourth upper elastic units 150-1 to 150-4, and may electrically connect the 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 (e.g., n=4) of the circuit board 250.

[0325] The support members 220-1 to 220-4 may be spaced apart from the housing 140 and are not fixed to the housing 140, and 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.

[0326] 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.

[0327] The first coil 120 may be electrically connected to the first and second lower elastic units 160-1 and 160-2.

[0328] For example, the coil 120 may be directly connected or coupled to 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 may be provided with a groove 18a for guiding the coil 120.

The second support member 220-2 may be disposed at a 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. The third support member 220-3 may be disposed at 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. 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.

[0330] The first terminal B1 of the circuit board 190 may be electrically connected to the first support member 220-1 by the first upper elastic unit 150-1, the second terminal B2 of the circuit board 190 may be electrically connected to the second support member 220-2 by the second upper elastic unit 150-2, the third terminal B3 of the circuit board 190 may be electrically connected to the third support member 220-3 by the third upper elastic unit 150-3, and the fourth terminal B4 of the circuit board 190 may be electrically connected to the fourth support member 220-4 by the fourth upper elastic unit 150-4.

[0331] The first to fourth support members 220-1 to 220-4 may be electrically connected to corresponding ones of the first to fourth terminals (eg, 251-1 to 251-n, n=4) of the circuit board 250, respectively.

[0332] For example, power signals VDD and GND may be provided to the first and second support members 220-1 and 220-2 through first and second terminals (eg, 251-1 and 251-2) of the circuit board 250.

[0333] For example, power signals VDD and GND may be provided to the first and second terminals B1 and B2 of the circuit board 190 via the first and second support members 220-1 and 220-2 and the first and second upper elastic units 150-1 and 150-2. The first position sensor 170 may receive the power signals VDD and GND via the first and second terminals B1 and B2 of the circuit board 190.

[0334] For example, the first terminal B1 of the circuit board 190 may be either a VDD terminal or a GND terminal, and the second terminal B2 of the circuit board 190 may be the remaining terminal of the VDD terminal and the GND terminal.

[0335] Also, a clock signal SCL and a data signal SDA may be provided to the third and fourth support members 220-3 and 220-4 via third and fourth terminals (eg, 251-3 to 251-4) of the circuit board 250.

[0336] 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.

[0337] 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 supporting 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 supporting member 220-2, the second upper elastic unit 150-2, and a second terminal B2 of the circuit board 190.

[0338] In addition, 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.

[0339] 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.

[0340] 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 solder 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 solder or a conductive adhesive member.

[0341] 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.

[0342] For example, the first hole 82a may be provided in the first bonding portion 81a of the first lower elastic unit 160-1, and the second hole 82b may be provided in the second bonding portion 81b of the second lower elastic unit 160-2.

[0343] For example, each of the first and second holes 82a, 82b may penetrate the second outer frame 161-1 and may have an opening that opens to one side of the second outer frame 161-1, but is not limited to this, and in other embodiments, the holes may not have an opening that opens to one side of the second outer frame 161-1.

[0344] 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 coupled to the first bonding portion 81a (or the second bonding portion 81b) provided with the first groove 82a (or the second groove 82b) by solder or a conductive adhesive member, thereby increasing the bonding area and improving the bonding strength and solderability between the two.

[0345] 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 can 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.

[0346] 12, the housing 140 may include a groove 31 recessed from a bottom surface of the first side portion 141-1. For example, the bottom surface of the groove 31 of the housing 140 may have a step with respect to the bottom 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 bottom surface of the housing 140.

[0347] 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.

[0348] In addition, the groove 31 of the housing 140 may overlap the holes 82a and 82b of the second outer frame 162-1 of the first and second lower elastic units 160-1 and 160-2 in the optical axis direction, but is not limited thereto. In other embodiments, they may not overlap.

[0349] The groove 31 in the housing 140 can increase the area of ​​the fifth and sixth terminals B5, B6 of the circuit board 190 exposed from the housing 140, can secure space for the solder or conductive adhesive material to be seated, can improve solderability, can reduce the degree to which the solder protrudes below the underside of the second outer frame 162-1, and can suppress or prevent spatial interference with the second coil 230, circuit board 250, or base 210 arranged below the lower elastic unit.

[0350] In addition, the lower surface 11c of the first magnet 130 disposed on the seating 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. This is to reduce the distance between the second coil 230 and the first magnet 130 to improve the electromagnetic force for driving the OIS.

[0351] In other embodiments, the lower surface of the first magnet 130 may be higher than or equal to the lower surfaces of the second outer frames 162-1 to 162-3 or the lower surface of the housing 140.

[0352] In order to space the first magnet 130 away 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.

[0353] Each of the upper elastic member 150, the lower elastic member 160, and the support member 220 may be a member that has conductivity and can be supported by elasticity.

[0354] For example, the upper and lower elastic members 150, 160 may be implemented as leaf springs, and the support member 220 may be implemented as 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.

[0355] In order to absorb and cushion the vibrations of the bobbin 110, the lens driving device 100 may be provided with a damper disposed between the upper elastic member 150 (or the lower elastic member 160) and the bobbin 110, or / and between the upper elastic member 150 (or the lower elastic member 160) and the housing 140.

[0356] For example, the damper DA1 (see FIG. 11) may be disposed in a space between the frame connecting parts 153, 163 of the upper elastic member 150 (or the lower elastic member 160) and the bobbin 110. Alternatively, for example, the damper DA2 may be disposed in a space between the frame connecting parts 153, 163 of the upper elastic member 150 (or the lower elastic member 160) and the housing 140.

[0357] Also, for example, the damper DA3 may be disposed between the connection portion 530 of the outer frame 152 of the upper elastic member 150 and the housing 140.

[0358] Also, for example, the dampers may be disposed at one end of the support members 220-1 to 220-4. For example, the damper DA4 may be disposed in the hole 147 of the housing 140.

[0359] FIG. 11 is a diagram showing a portion of the damper disposed on the upper elastic member 150-1, the bobbin 110, the housing 140, and the support member 220-1, and the damper can be similarly applied to the other upper elastic members 150-2 to 150-4, the bobbin 110, the housing 140, and the other support members 220-2 to 220-4.

[0360] Also, the embodiment may include at least one of the dampers DA1 to DA5 in FIG.

[0361] Next, the base 210, the circuit board 250, and the second coil 230 will be described.

[0362] 13a, 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 have a through-hole shape that penetrates the base 210 in the optical axis direction.

[0363] The base 210 may include a step portion 211 to which an adhesive is applied when adhesively fixing the cover member 300. Here, the step portion 211 may guide the side plate 302 of the cover member 300 coupled to the upper side, and a lower end of the side plate 302 of the cover member 300 may contact the step portion 211. The step portion 211 of the base 210 and the lower end of the side plate 302 of the cover member 300 may be adhered or fixed by an adhesive or the like.

[0364] A support portion 255 may be provided in a region of the base 210 facing the terminal portion 253 having the terminals 251-1 to 251-n of the circuit board 250. The support portion 255 may support the terminal portion 253 of the circuit board 250. For example, the support portion 255 may have a groove shape recessed from the outer surface of the base 210, but is not limited thereto, and in other embodiments, the support portion 255 may be flush with the outer surface of the base 210 or may have a protruding shape.

[0365] A protrusion or projection 48 extending or protruding toward an outer surface of the base 210 may be formed on a side of the circuit board 250. The protrusion 250 may protrude from the outer surface of the circuit board 250 toward the outer surface of the base 210. A groove or coupling groove 28 having a corresponding shape may be formed on the outer surface of the base 210 at a position corresponding to the protrusion 48 of the circuit board 250. The protrusion 48 of the circuit board 250 may be disposed, coupled, or seated in the groove 28 of the base 210.

[0366] 13a and 13b, the base 210 may include corner regions (or "corner regions") 212 that correspond to the corners of the cover member 300. For example, the base 210 may include four corner regions 212.

[0367] The base 210 may include a corner region 212 in which a first surface 21A is formed that forms a first step H1 with respect to an upper surface 21 of the base 210 in the direction of the optical axis OA.

[0368] The corner region 212 of the base 210 may be provided with a step portion 212A for avoiding spatial interference with the elastic connecting portions 25 (25-1 to 25-4) of the circuit board 250.

[0369] Due to the step portion 212A, a certain gap can be present between the connecting elastic portions 25-1 to 25-4 and the base 210, thereby enabling the OIS to be driven.

[0370] For example, corner region 212 can be a region of base 210 that includes and is adjacent to corner 20A of base 210.

[0371] The step portion 212A may include a first surface 21A that forms a first step H1 in the direction of the optical axis OA with respect to the upper surface 21 of the base 210. For example, the upper surface 21 of the base 210 may be a surface that faces and contacts or is in close contact with the lower surface of the circuit board 250.

[0372] For example, the distance from the lower surface 22 of the base 210 (see FIG. 17) to the first surface 21A of the base 210 may be smaller than the distance from the lower surface 22 of the base 210 to the upper surface 21 of the base 210.

[0373] Moreover, the step portion 212A may further include a second surface 21B that forms a second step H2 with respect to the upper surface 21 of the base 210 in the direction of the optical axis OA.

[0374] The distance from the lower surface 22 of the base 210 to the second surface 21B of the base 210 may be smaller than the distance from the lower surface 22 of the base 210 to the upper surface 21 of the base 210.

[0375] In addition, the distance from the lower surface 22 of the base 210 to the second surface 21B of the base 210 may be greater than the distance from the lower surface 22 of the base 210 to the first surface 21A of the base 210.

[0376] For example, the first step H1 may be larger than the second step H2 (H1>H2).

[0377] For example, each of the first surface 21A and the second surface 21B may be parallel to the upper surface 21 or the lower surface 22 of the base 210, but is not limited thereto, and in other embodiments, the two may not be parallel to each other. Each of the first surface 21A and the second surface 21B may be flat, but is not limited thereto, and in other embodiments, at least one of the first surface and the second surface may be or include a curved surface.

[0378] In addition, the step portion 212A may further include a third surface 21C connecting the first surface 21A and the second surface 21B of the base 210. In addition, the step portion 212A may further include a fourth surface 21D connecting the second surface 21B of the base 210 and the upper surface 21 of the base 210.

[0379] For example, each of the third surface 21C and the fourth surface 21D of the base 210 may be perpendicular to the top surface 21 of the base 210, but is not limited to this, and in other embodiments, each of the third surface 21C and the fourth surface 21D of the base 210 may be an inclined surface inclined at a certain angle with respect to the top surface 21 of the base 210.

[0380] 13b, the first surface 21A may be disposed in the center of the corner region 212, and the second surfaces 21B may be disposed on both sides of the first surface 21A. For example, the step portion 212A may have one first surface 21A and a second surface 2B including a 2-1 surface 21B1 located on one side of the first surface 21A and a 2-2 surface 21B2 located on the other side of the first surface 21A.

[0381] In other embodiments, the corner region 212 of the base 210 may include at least one first surface and at least one second surface.

[0382] The step portion 212A can overlap in the optical axis direction with the elastic connecting portions 25-1 to 25-4 of the circuit board 250, which will be described later.

[0383] The role of the step portion 212A is to leave or avoid spatial interference between the base 210 and the supporting members 220-1 to 220-4, the connecting elastic portions 25-1 to 25-4, and the adhesive members (or solder 902) that connect the supporting members 220-1 to 220-4 and the connecting elastic portions 25-1 to 25-4.

[0384] In addition, a damper may be disposed between the step portion 212A and the connecting elastic portions 25-1 to 25-4, and the step portion 212A may play a role in accommodating or supporting the damper.

[0385] In addition, as shown in FIG. 17, since the corner region 212 of the base 210 is not an open structure, the step portion 212A may collect foreign matter generated during a soldering process between the circuit board 250 and the support member 220, thereby preventing the foreign matter from deteriorating the performance and reliability of the image sensor of the camera module.

[0386] In addition, in a lens driving device having an open corner structure of the base 210, additional processes may be required to close or seal such open structure, which may increase process costs, but the embodiment can reduce process costs due to such additional processes.

[0387] In another embodiment, instead of the step 212A, a groove recessed from the upper surface 21 of the base 210 may be formed in the corner region 212 of the base 210.

[0388] FIG. 14 shows a base 210-1 according to another embodiment, in which the corner region 212 of the base 210-1 may include a step portion 212A and a guide portion 218 that protrudes upward or in the optical axis direction from the first surface 21A of the step portion 212A and surrounds the corner region 212.

[0389] The corner region 212 can be located inside the guide portion 218 .

[0390] An upper surface or an upper end of the guide portion 218 may be positioned higher than the second surface 21B of the stepped portion 212A. Also, for example, the upper surface or an upper end of the guide portion 218 may be positioned higher than the upper surface of the base 210-1. Also, for example, the upper surface or an upper end of the guide portion 218 may be positioned higher than the upper surfaces of the connecting elastic portions 25-1 to 25-4.

[0391] The guide portion 218 can guide the seating or placement of the second damper 310A, which will be described later. The connecting elastic portions 25-1 to 26-4 can be disposed inside the guide portion 218.

[0392] 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 is disposed.

[0393] For example, the first seating groove 215-1 of the base 210 may be formed adjacent to one escape portion 212-3 provided at any corner of the base 210, and the second seating groove 215-2 of the base 210 may be formed adjacent to another escape portion 212-4 provided at the other corner of the base 210.

[0394] For example, the first seating groove 215-1 of the base 210 may be formed on the upper surface of the base 210 located between any of the escape portions 212-3 and the protrusion 19, and the second seating groove 215-2 may be formed on the upper surface of the base 210 located between the other escape portion 212-4 and the protrusion 19.

[0395] Also, for example, a seat (not shown) on which the filter 610 of the camera module 200 is mounted may be formed on the lower surface of the base 210 .

[0396] 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.

[0397] 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 parts spaced apart from each other.

[0398] 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 .

[0399] 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 have a shape 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.

[0400] The second coil 230 may be disposed on the top of the circuit board 250 , and the OIS position sensors 240 a , 240 b may be disposed in the seating grooves 215 - 1 , 215 - 2 of the base 210 located below the circuit board 250 .

[0401] 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 operating unit in a direction perpendicular to the optical axis. Here, the OIS operating unit may include an AF operating unit and components mounted in the housing 140.

[0402] For example, the OIS operating portion may include an AF operating portion and a housing 140, and in some embodiments, the OIS operating portion may include a first magnet 130.

[0403] The circuit board 250 is disposed on the upper surface 21 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 have the form of a through-hole.

[0404] The circuit board 250 is disposed on the upper surface 21 of the base 210 and may include a body 252 in which an opening C2 is formed, and at least one terminal portion 253 bent and extending from the body 252.

[0405] The shape of the body 252 may have a shape that matches or corresponds to the top surface of the base 210, for example, a rectangular shape.

[0406] The terminal unit 253 may be bent from an upper surface of the body 252 to extend to an outer surface of the base 210. The terminal unit 253 may include a plurality of terminals 251-1 to 251-n (n is a natural number less than 1) or pins that receive an electrical signal from the outside.

[0407] For example, referring to FIG. 15, the circuit board 250 may include two terminal portions 253 facing or located on opposite sides of each other, but is not limited thereto, and the number of terminal portions 253 may be one or more.

[0408] The second coil 230 may be disposed below the bobbin 110 .

[0409] For example, the second coil 230 may be disposed below the housing 140. Also, for example, the second coil 230 may be disposed below the lower elastic member 160. The second coil 230 may be disposed on the circuit board 250.

[0410] The second coil 230 may include coil units corresponding to or facing the magnets 130-1 to 130-4 arranged in the housing 140. For example, the coil units 230-1 to 230-4 may be arranged on the circuit board 250.

[0411] For example, the second coil units 230-1 to 230-4 may 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 may overlap with the magnets 130-1 to 130-4 in the optical axis direction.

[0412] 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.

[0413] The shape of the circuit member 231 may have a shape that matches or corresponds to the top surface of the base 210 (or the circuit board 250), for example, a rectangle.

[0414] 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.

[0415] For example, each of the coil units 230-1 to 230-4 can have a closed curve shape, such as a ring shape, rotating around the optical axis when viewed from above.

[0416] Each of the coil units 230-1 to 230-4 may have a coil block shape formed of a fine pattern (FP) coil, but is not limited thereto.

[0417] 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 disposed 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.

[0418] For example, the second coil 230 may include, but is not limited to, two second direction coil units 230-1, 230-3 and two third direction coil units 230-2, 230-4.

[0419] For example, two coil units 230-1, 230-3 may be arranged in two corner regions of the circuit member 231 facing in a first diagonal direction of the circuit member 231, and the other two coil units 230-2, 230-4 may be arranged in the other two corner regions of the circuit member 231 facing in a second diagonal direction of the circuit member 231.

[0420] The first diagonal direction and the second diagonal direction may be 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.

[0421] For example, the second direction coil units 230-1 and 230-3 can act in the same direction due to the electromagnetic forces generated by the interaction with the magnets 130-1 and 130-3 corresponding to the optical axis direction, and the third direction coil units 230-2 and 230-4 can act in the same direction due to the electromagnetic forces generated by the interaction with the magnets 130-2 and 130-4 corresponding to the optical axis direction.

[0422] 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.

[0423] 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.

[0424] 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.

[0425] Interaction between the magnets 130-1 to 130-4 and the second coils 230-1 to 230-4 to which driving signals are provided allows the housing 140 to move in a second direction and / or a third direction, for example, the X-axis direction and / or the Y-axis direction, thereby performing camera shake correction.

[0426] 15 and 16, the second coil 230 may include terminals 30A to 30D for receiving a driving signal from a circuit board 250. As shown in FIG.

[0427] 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 a lower surface of the circuit member 231. Here, the lower surface of the circuit member 231 may be a surface facing the upper surface of the circuit board 250.

[0428] 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 and 30D of the circuit member 231 may be disposed on the lower surface of the circuit member 231 adjacent to the 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.

[0429] The other two terminals 30A, 30C of the circuit member 231 may be disposed on the underside of the circuit member 231 adjacent to the second side 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 and the second side of the circuit member 231 may face each other or be located on opposite sides.

[0430] For example, the first coil unit 230-1 and the third coil unit 230-4 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.

[0431] 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 230-3 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.

[0432] Also, 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.

[0433] 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 expressed as "terminals" or "bonding parts".

[0434] 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.

[0435] For example, pads 27a-27d of circuit board 250 may be disposed or provided on the underside of circuit board 250, but are not limited to this, and in other embodiments, the pads may be formed on at least one of the upper and lower surfaces of circuit board 250.

[0436] Each of the pads 27a-27d of the circuit board 250 may have a groove that exposes 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 may be electrically connected to each other.

[0437] 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 of the circuit board 250 on which the terminal portion 253 is not formed.

[0438] For example, the two pads 27a, 27c may be disposed on the underside of the circuit board 250 adjacent to the first outer side 33-1 of the circuit board 250, and the other two pads 27b, 27d may be disposed on the underside of the circuit board 250 adjacent to the second outer side 33-2 of the circuit board 250, and the first outer side 33-1 and the second outer side 33-2 may be located on opposite sides to each other. Also, the terminal portion 253 may be disposed on the third and fourth outer sides 33-3, 33-4 of the circuit board 250, and the third outer side 33-3 and the fourth outer side 33-4 may be located on opposite sides to each other.

[0439] For example, two second direction coil units 230-1, 230-3 may be connected in series with each other, one end of the serially connected coil units 230-1, 230-3 may be electrically connected to a first pad 27a of the circuit board 250, and the other end of the serially connected coil units 230-1, 230-3 may be electrically connected to a second pad 27b of the circuit board 250.

[0440] Also, for example, two third direction coil units 230-2, 230-4 may be connected in series with each other, one end of the serially 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 serially connected coil units 230-2, 230-4 may be electrically connected to the fourth pad 27d of the circuit board 250.

[0441] 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.

[0442] 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 two other corresponding terminals of the circuit board 250.

[0443] In another embodiment, the terminals of the circuit member 231 may be formed on an inner circumferential surface of the circuit member 231 defined by the opening C1 and / or on a lower surface of the circuit member 231 adjacent to the inner circumferential surface. Also, the pads of the circuit board 250 may be formed on an inner circumferential surface of the body 252 of the circuit board 250 defined by the opening C2 and / or on a lower surface of the body 252 of the circuit board 250 adjacent to the inner circumferential surface.

[0444] In FIG. 13a, the coil units 230-1 to 230-4 are embodied 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.

[0445] In another embodiment, the coil units 230-1 to 230-4 may be embodied in the form of a ring-shaped coil block with the circuit member 231 omitted.

[0446] In still another embodiment, the coil units 230-1 to 230-4 may be embodied 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 expressed as a "circuit member" or a "board". In this case, the other end of the support member may be coupled to a "circuit member (e.g., a lower surface of the circuit member)", and the circuit member may include a board portion (or body) on which the coil units 230-1 to 230-4 are formed and a terminal portion on which the terminals are formed. The description of the circuit board 250 may be applied or mutatis mutandis to the board portion, and the description of the terminal portion 253 of the circuit board 250 may be applied or mutatis mutandis to the terminal portion.

[0447] Also, 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 .

[0448] In order to avoid spatial interference with the support member 220 , the corners of the circuit member 231 may be provided with escape portions 23 , and the escape portions 23 may have the form of chamfers at the corners of the circuit member 231 .

[0449] For example, since the escape portion 23 must avoid spatial interference with the connecting elastic portions 25-1 to 25-4 described later, the escape portion 23 ensures that the circuit member 231 does not overlap at least the connecting elastic portions 25-1 to 25-4 in the optical axis direction.

[0450] In other embodiments, the relief portion of the circuit member may have the form of a relief groove.

[0451] The circuit member 231 may include an escape groove 24 for avoiding 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 so as 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.

[0452] Each of the OIS position sensors 240a, 240b may be a Hall sensor, and any sensor capable of detecting the strength of a magnetic field may be used. For example, each of the OIS position sensors 240a, 240b may be implemented as a position detection sensor such as a Hall sensor alone, or may be implemented in the form of a driver including a Hall sensor. When the OIS position sensors 240a, 240b have the form of a driver including a Hall sensor, the description of FIG. 7b may be applied or mutatis mutandis.

[0453] Each of the OIS position sensors 240a and 240b can detect the strength of the magnetic field of the magnets 130-1 to 130-4 caused by the movement of the OIS operating unit in a direction perpendicular to the optical axis, and output an output signal according to the detected result. The displacement of the OIS operating unit can be detected using the output signals of the OIS position sensors 240a and 240b, and the control units 830 and 780 can perform OIS feedback camera shake correction using the output signals of the OIS position sensors 240a and 240b.

[0454] For example, the first OIS position sensor 240a may overlap 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 overlap a second line connecting a second corner of the circuit board 250 and the center of the opening C2 of the circuit board 250.

[0455] For example, the center of the first OIS position sensor 240a can be aligned with or overlap a first line, and the center of the second OIS position sensor 240b can be aligned with or overlap a second line, and the first line and the second line can be perpendicular to each other.

[0456] The terminal portion 253 of the circuit board 250 may be provided with terminals 251-1 to 251-n.

[0457] Signals SCL, SDA, VDD, and GND for data communication with the first position sensor 190 can be transmitted and received via a plurality of terminals 251-1 to 251-n provided on the terminal portion 253 of the circuit board 250, drive 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 to the outside.

[0458] According to an embodiment, the circuit board 250 may be a flexible printed circuit board (FPCB). 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.

[0459] Since the embodiment has a structure in which a 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 in which a driving signal is provided directly to the first coil 120 via the circuit board 250.

[0460] In addition, since the first position sensor 170 can be implemented as 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 constant slope due to temperature changes, thereby improving the accuracy of AF operation regardless of temperature changes.

[0461] 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.

[0462] The cover member 300 may have a box shape with 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 step 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 a circle or a polygon, for example, a rectangle or an octagon, but is not limited thereto.

[0463] The cover member 300 may have an opening 303 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 it may also 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.

[0464] In order to reduce the length of a path through which the power signals GND and VDD are transmitted to the first position sensor 170, the following configuration may be provided.

[0465] First, the first and second terminals B1, B2 of the circuit board 190, to which the power signals GND, VDD are provided, are electrically connected to the first and second support members 220-1, 220-1 arranged at two corner portions 142-1, 142-2 adjacent to the first side portion 141-1 of the housing 140 in which the first position sensor 170 is arranged, thereby reducing the number of paths.

[0466] In addition, the first and second terminals B1 and B2 of the circuit board 190 are disposed in the body portion S1 of the circuit board 190, thereby reducing the number of paths.

[0467] In addition, the first terminal B1 of the circuit board 190 is disposed at one end of the circuit board 190 so that it 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 disposed at the other end of the circuit board 190 so that it overlaps with the second corner portion 142-2 of the housing 140 in the optical axis direction, thereby reducing the number of paths.

[0468] In addition, 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.

[0469] 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.

[0470] By reducing the path 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).

[0471] In addition, 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 each have a first outer frame that is coupled to the housing 140, but do not have a first inner frame 151 and a first frame connection portion, so that resistance can be reduced compared to the second and fourth upper elastic units 150-3 and 150-4.

[0472] For the reasons described above, the embodiment reduces the length of the path through which the power signals GND and 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 and 150-2), thereby preventing the power signals GND and VDD from decreasing, reducing power consumption, and reducing the operating voltage of the driver IC of the first position sensor 170.

[0473] In the embodiment, the first to sixth terminals P1 to P6 may be disposed on the second surface 19a of the circuit board 190 to facilitate soldering for electrical connection with the first to fourth extension portions P1 to P4 of the upper elastic units 150-1 to 150-4 and improve solderability.

[0474] 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 may deteriorate, and foreign matter (e.g., contaminants) caused by the solder may flow into the interior of the lens driving device 100, which may cause the lens driving device to malfunction.

[0475] 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.

[0476] The fifth and sixth terminals B5, B6 of the circuit board 190 may be disposed on the extension S2 of the circuit board 190 for easy coupling with the lower elastic units 160-1, 160-2.

[0477] In the embodiment, the magnetic field interference between the first and second magnets 180, 185 and the first magnet 130 is reduced, so that the reduction in the AF driving force caused by the magnetic field interference can be prevented, and thus the desired AF driving force can be obtained without providing a separate yoke.

[0478] 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 driving device.

[0479] 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.

[0480] In addition, instead of reducing the number of support members, the thickness of the support members can be increased to obtain the same elastic force, and by increasing the thickness of the support members, the effect of external impacts on the OIS operating part can be reduced.

[0481] FIG. 18a is a perspective view of the circuit board 250 of FIG. 13a, and FIG. 18b is an enlarged view of the elastic connecting portions 25-1 to 25-4 of the circuit board 250 of FIG. 18a.

[0482] 18a and 18b, the circuit board 250 may include elastic connection parts 25-1 to 25-4 coupled to the support member 220. The elastic connection parts 25-1 to 25-4 may extend from corner regions of the circuit board 250 and be coupled to other ends of the support members 220-1 to 220-4.

[0483] The elastic connecting portions 25-1 to 25-4 may be alternatively expressed as "buffer portions", "elastic portions", or "spring portions".

[0484] The elastic connection parts 25-1 to 25-4 may be disposed at the corners or corner regions of the body 252 of the circuit board 250.

[0485] The elastic connection parts 25-1 to 25-4 may extend from the body 252 of the circuit board 250 to the supporting members 220-1 to 220-4, and may be coupled to the other ends of the supporting members 220-1 to 220-4 by solder 902 or a conductive adhesive member.

[0486] The circuit board 250 may have a recess 125A formed at a corner or corner region of the body 252 to avoid spatial interference with the support member 220. For example, the recess 125A may have a shape in which the corner or corner region of the body 252 is chamfered, but is not limited thereto, and the recess of the circuit board 250 may be embodied in various shapes that allow the support member 220 to escape.

[0487] A connecting outer surface 33-5 (or a fifth outer surface) may be formed at a corner or corner region of the body 252 of the circuit board 250, connecting two adjacent outer surfaces 33-1 and 33-3, 33-2 and 33-3, 33-2 and 33-4, and 33-4 and 33-1 of the circuit board 250.

[0488] The connecting elastic portions 25-1 to 25-4 can extend and protrude from the connecting outer surface 33-5.

[0489] For example, the elastic connection parts 25-1 to 25-4 may include a coupling part 60A to which the other ends of the support members 220-1 to 220-4 are coupled, and a connecting part 60B that connects the first coupling part 60A to the body 252 of the circuit board 250. The connecting part 60B may extend from the body 252 and be coupled to the coupling part 60A, and the connecting part 60B may be alternatively expressed as an "extension part."

[0490] The coupling portion 60A may be alternatively expressed as a "first portion," and the connecting portion 60B may be alternatively expressed as a "second portion."

[0491] The connecting elastic parts 25-1 to 25-4 may be elastic members. For example, the connecting elastic parts 25-1 to 25-4 may have the shape of a leaf spring like the upper elastic member 150 and the lower elastic member 160, but are not limited thereto.

[0492] The elastic connecting parts 25-1 to 25-4 may include a conductive material and may electrically connect the supporting members 220-1 to 220-4 and the terminals 251 of the circuit board 250.

[0493] The connecting elastic parts 25-1 to 25-4 may have holes 250a through which the supporting members 220-1 to 220-5 pass. For example, the coupling part 60A may have holes 250a through which the supporting members 220-1 to 220-5 pass. The holes 250a may be through holes that pass through the coupling part 60A.

[0494] For example, the coupling portion 60A may include a hole 250a, and may include a portion of the elastic connecting portions 25-1 to 25-4 adjacent to the hole 250a in which the solder or conductive adhesive member is disposed.

[0495] The connecting portion 60B may have a shape that is bent or folded at least once. The connecting portion 60B may include a zigzag shape, at least one curved section, or a bent section.

[0496] For example, connecting portion 60B may include a first connecting portion (or “first extension portion”) 61 extending or protruding from one region of the corner of body 252, a second connecting portion (or “second extension portion”) 62 extending or protruding from another region of the corner of body 252 and connected to first connecting portion 61, and a third connecting portion (or “third extension portion”) 63 connected to at least one of first connecting portion 61 and second connecting portion 62 and connected to coupling portion 60A.

[0497] For example, the first connecting portion 61 may extend from a first region 37-1 of a connecting outer surface 33-5 adjacent to one (eg, 33-3) of two adjacent outer surfaces (eg, 33-1, 33-3) of the body 252.

[0498] For example, the first connecting part 61 may have a line shape, and may have a straight line shape. In other embodiments, the first connecting part may have a curved line shape that bends one or more times. For example, the first connecting part may have a zigzag shape, and may include at least one curved or bent section. In yet other embodiments, the first connecting part may have a line shape that includes a curved portion and a straight portion.

[0499] Also, for example, the second connecting portion 62 may extend from the second region 37-2 of the connecting outer surface 33-5 adjacent to the other one (e.g., 33-1) of the two adjacent outer surfaces (e.g., 33-1, 33-3) of the body 252, and may be connected to the first connecting portion 61.

[0500] For example, the second connecting part 62 may have a line shape, and may have a straight line shape. In other embodiments, the second connecting part may have a line shape that is curved and bent one or more times. For example, the second connecting part may have a zigzag shape, and may include at least one curved or bent section. In yet other embodiments, the second connecting part may have a line shape that includes a curved section and a straight section.

[0501] For example, the third connecting portion 63 may connect between the joining portion 60A and the portion where the first connecting portion 61 and the second connecting portion 62 meet.

[0502] For example, the third connecting part 63 may have a line shape, and may have a straight line shape. In other embodiments, the third connecting part may have a curved line shape that bends one or more times. For example, the third connecting part may have a zigzag shape, and may include at least one curved or bent section. In yet other embodiments, the third connecting part may have a line shape that includes a curved portion and a straight portion.

[0503] For example, the third connecting portion 63 may form a single contact between the coupling portion 60A and the connecting portion 60B.

[0504] For example, the other end of each of the supporting members 220-1 to 220-4 coupled to the coupling portion 60A may be located between the connecting portion 60B and a corner or corner region of the body 252. Or, for example, the other end of each of the supporting members 220-1 to 220-4 coupled to the coupling portion 60A may be located inside the connecting portion 60B.

[0505] For example, the connecting elastic parts 25-1 to 25-4 may include a portion where the width increases and then decreases from one end of the connecting part 60B to the joining part 60A. One end of the connecting part 60B may be a portion where the connecting part 60B and the body 252 meet.

[0506] The connecting portion 60B may include a portion whose width decreases in a direction from a corner or corner region of the body 252 toward the supporting members 220-1 to 220-4.

[0507] For example, the width W1 of the first connecting portion 61 may be the same as the width W2 of the second connecting portion 62. This is so that the connecting elastic portions 25-1 to 25-4 support the OIS operating portion in a balanced manner. For example, the first connecting portion 61 and the second connecting portion 62 may have shapes symmetrical to each other with respect to the third connecting portion 63. For example, the width of the first connecting portion 61 may be symmetrical to the width of the second connecting portion 62 with respect to the third connecting portion 63.

[0508] In other embodiments, the width W1 of the first connecting portion 37-1 may be different from the width W2 of the second connecting portion 37-2. For example, the width W1 of the first connecting portion 37-1 may be smaller than the width W2 of the second connecting portion 37-2. In other embodiments, the width W1 of the first connecting portion 37-1 may be larger than the width W2 of the second connecting portion 37-2.

[0509] The first connecting portion 61 may include a portion whose width decreases from one end of the first connecting portion 61 (or a corner of the body 252) toward the support member 220. In addition, the second connecting portion 62 may include a portion whose width decreases from one end of the second connecting portion 62 (or a corner of the body 252) toward the support member 220.

[0510] The width W1 of the first connecting portion 61 may gradually decrease in a direction from one end of the first connecting portion 61 to the other end of the first connecting portion 61.

[0511] One end of the first connecting portion 61 may be a portion connected to the body 252 of the circuit board 250, and the other end of the first connecting portion 61 may be a portion connected to the second connecting portion 62 (or / and the third connecting portion 64).

[0512] For example, the width of one end of the first connecting portion 61 may be greater than the width of the other end of the first connecting portion 61, but is not limited to this, and in other embodiments, the two may be the same.

[0513] The width W2 of the second connecting portion 62 may gradually decrease in a direction from one end of the second connecting portion 62 to the other end of the second connecting portion 62.

[0514] One end of the second connecting portion 62 may be a portion connected to the body 252 of the circuit board 250, and the other end of the second connecting portion 62 may be a portion connected to the first connecting portion 61 (or / and the third connecting portion 64).

[0515] For example, the width of one end of the second connecting portion 62 may be greater than the width of the other end of the second connecting portion 62, but is not limited to this, and in other embodiments, the two may be the same.

[0516] Also, for example, the width of one end of the first connecting portion 61 may be larger than the width of the other end of the first connecting portion 61, and the width of one end of the second connecting portion 62 may be larger than the width of the other end of the second connecting portion 62. This is because, by making the width of one end of each of the first and second connecting portions 61, 62 relatively larger than the width of the other end of each of the first and second connecting portions 61, 62, the connecting elastic portions 25-1 to 25-4 can be stably supported by the body 252 of the circuit board 250, and the elastic force of the connecting elastic portions in the optical axis direction can be increased and the elastic force of the connecting elastic portions in the direction perpendicular to the optical axis can be decreased, thereby stably supporting a large-diameter lens.

[0517] For example, the width W3 of the third connection part 63 may be larger than the width W1 of the first connection part 61 and the width W2 of the second connection part 62 (W3>W1, W3>W2). As described below, the first damper 310 may be disposed between the third connection part 63 and the body 252 (e.g., the escape part 125A) to connect the second connection part 63 and the body 252 to each other. Here, since W3>W1 and W3>W2, the contact area between the third connection part 63, the body 252, and the first damper 310 may be increased, and thus the quality factor (Q) that determines the resonance frequency of the frequency response characteristic due to the OIS drive may be reduced. Since the quality factor is reduced, the gain value of the frequency response characteristic at the first resonance frequency may be reduced, and the second resonance frequency and the third resonance frequency may have high values, thereby improving the oscillation phenomenon of the OIS operating part, improving the accuracy of the OIS feedback operation, and improving the image quality of the camera module.

[0518] In another embodiment, the width W3 of the third connecting portion 63, the width W1 of the first connecting portion 61, and the width W2 of the second connecting portion 62 may be the same as each other. In yet another embodiment, the width W3 of the third connecting portion 63 may be smaller than at least one of the width W1 of the first connecting portion 61 and the width W2 of the second connecting portion 62.

[0519] Here, the width of each of the first to third connecting portions 61 to 63 may be a length in a direction perpendicular to the longitudinal direction (or extension direction) of each of the first to third connecting portions 61 to 63.

[0520] The width of the coupling portion 60A may be the same as the width W3 of the third connecting portion 63. For example, the width of the coupling portion 60A may be larger than the width W1 of the first connecting portion 61 and the width W2 of the second connecting portion 62. This is because holes 250a to be coupled to the other ends of the support members 220-1 to 220-4 are formed in the coupling portion 60A, and a sufficient area must be secured for coupling to the support members 220-1 to 220-4 by solder 902 or a conductive adhesive member. This is also to secure a contact area between the coupling portion 60A and the first damper 310.

[0521] In other embodiments, the width of the coupling portion 60A may be greater than the width of the third connecting portion 64. In yet other embodiments, the width of the coupling portion 60A may be less than the width of the third connecting portion 64.

[0522] For example, the widths W1, W2, and W3 of the connecting elastic portion 25-1 may be greater than the width W11 of the connecting portion 530 of the outer frame 152 of the upper elastic member 150 (see FIG. 10).

[0523] The thickness T1 of the elastic connecting parts 25-1 to 25-4 may be smaller than the thickness T2 of the body 252 of the circuit board 250 (T1 <T2)。

[0524] The thickness T1 of the connecting elastic parts 25-1 to 25-4 may be the length of the connecting elastic parts 25-1 to 25-4 in the optical axis direction, and the thickness of the body 252 may be the length of the body 252 in the optical axis direction.

[0525] For example, the spring constant of the connecting elastic parts 25-1 to 25-4 may be greater than the spring constant of the upper elastic member 150.

[0526] For example, the spring constant of the connecting elastic parts 25-1 to 25-4 in a direction perpendicular to the optical axis direction (for example, the X-axis direction or the Y-axis direction) may be greater than the spring constant of the upper elastic member 150 in a direction perpendicular to the optical axis direction.

[0527] Alternatively, for example, the spring constant of the connecting elastic parts 25-1 to 25-4 in the optical axis direction (for example, the Z-axis direction) may be greater than the spring constant of the upper elastic member 150 in the optical axis direction.

[0528] The connecting elastic parts 25-1 to 25-4, the joining part 60A, the connecting part 60B, or the first connecting part 61, the second connecting part 62, or the third connecting part 63 may alternatively be expressed as "shock absorbing parts", "elastic parts", "spring parts", or "suspension parts".

[0529] In a general lens driving device in which a support member is directly connected to a body of a circuit board, a circuit member of a second coil, or a base, stress and fatigue accumulation applied to the support member may increase due to a large diameter lens. In addition, in this case, one end of the support member is connected to an upper elastic member, while the other end of the support member is fixed to a fixed part, the body of a circuit board, a circuit member of a second coil, or a base, so that the stress is concentrated at the other end of the support member, causing deformation of the support member.

[0530] By decreasing the spring constant of the upper elastic member, the stress applied to the support member can be decreased, but this may cause a problem of increasing the positional difference of the OIS operating part due to gravity.

[0531] Furthermore, in order to reduce the spring constant of the upper elastic member in order to reduce stress, the freedom of design of the upper elastic member is reduced, which may result in poor frequency response characteristics of the OIS drive, and may cause oscillation of the OIS operating part.

[0532] However, in the embodiment, by providing elastic connecting parts 25-1 to 25-4 which are elastic members directly connected to the other end of support member 220, the stress applied to the members due to the large diameter lens can be dispersed, and the accumulation of fatigue in the support members can be eliminated.

[0533] That is, since the coupling portion 60A of the connecting elastic parts 25-1 to 25-4 is spaced from the body 252, the supporting members 220-1 to 220-4 coupled to the coupling portion 60A according to the embodiment can easily move in the first direction. The supporting members 220-1 to 220-4 according to the embodiment can move more easily in the first direction than a general supporting member fixed to the body of a circuit board, thereby improving the accuracy of image stabilization and dispersing stress upon dropping and impact, thereby suppressing deformation and breakage of the supporting members 220-1 to 220-4.

[0534] In addition, since the connecting elastic parts 25-1 to 25-4 have a shape that is bent one or more times, the overall length of the connecting elastic parts 25-1 to 25-4 can be increased, and as a result, the embodiment can distribute the stress applied to the upper elastic member 150 and / or the support member 220 and prevent the connecting elastic parts from breaking due to the stress applied to the upper elastic member 150 and / or the support member 220 due to an impact.

[0535] In addition, since the spring constant of the elastic connectors 25-1 to 25-4 in the embodiment is greater than the spring constant of the upper elastic member, the strength of the elastic connectors 25-1 to 25-4 can be increased, thereby improving the positional difference of the OIS operating part caused by gravity.

[0536] In addition, since a single contact is formed between the coupling portion 60A and the connecting portion 60B by the third connecting portion 63, the ease of movement of the connecting elastic portions 25-1 to 25-4 in the first direction can be further improved, and the distribution of stress applied to the upper elastic member 150 and / or the support member 220 due to an impact can be further improved.

[0537] In addition, as described above, by increasing the strength of the elastic connectors 25-1 to 25-4, the embodiment can increase the secondary resonance frequency of the frequency response characteristics caused by the OIS drive, thereby suppressing the oscillation of the OIS operating part during the OIS drive. For example, the frequency response characteristics caused by the OIS drive can be the frequency response characteristics for the output signal output from the second position sensor 240.

[0538] Fig. 19a is a perspective view of a body 252-1 according to another embodiment of the circuit board 250 of Fig. 18a, and Fig. 19b is an enlarged view of the escape portion 125A1 of the body 252-1 of Fig. 19a. In Figs. 19a and 19b, the same reference numerals as in Figs. 18a and 18b denote the same components, and descriptions of the same components will be simplified or omitted.

[0539] 19a and 19b, the escape portion 125A1 of the body 252-1 of the circuit board 250 may be formed with an extension portion 41A extending toward the connecting elastic portions 25-1 to 25-4.

[0540] The body 252-1 may include an extension 41A extending toward the connecting elastic parts 25-1 to 25-4. For example, the extension 41A may at least partially overlap the first surface 21A of the step part 212A of the base 210 in the optical axis direction. The first damper 310 may connect the extension 41A of the body 252-1 and the connecting elastic parts 25-1 to 25-4 to each other.

[0541] The extension portion 41A may protrude from the connecting outer surface 33-5 toward the connecting elastic portions 25-1 to 25-4. For example, the extension portion 41A may protrude from the connecting outer surface 33-5 toward the coupling portion 60A of the connecting elastic portions 25-1 to 25-4.

[0542] The extension portion 41A can be alternatively expressed as a "protrusion" or a "damper guide portion."

[0543] The extension portion 41A can be separated from the connecting elastic portions 25-1 to 25-4.

[0544] The width W21 of the extension 41A may decrease in a direction from the extension 41A (or the center of the opening C2 of the circuit board 250) toward the coupling portion 60B. The width W21 of the extension 41A may be the length of the extension 41A in a direction perpendicular to the direction from the extension 41A (or the center of the opening C2 of the circuit board 250) toward the coupling portion 60B.

[0545] One end of the extension portion 41A may be provided with a hole 41B or a groove for increasing a contact area with the first damper 310. Here, one end of the extension portion 41A may be adjacent to and spaced from the coupling portion 60A.

[0546] For example, the hole 41B may have a recessed shape from the coupling portion 60A toward the extension portion 41A. Also, the hole 41B may have an opening toward the coupling portion 60A and may have a shape corresponding to a part of the coupling portion 60B.

[0547] For example, the hole 41B can overlap at least a portion with the first surface 21A of the step portion 212A of the base 210 in the optical axis direction.

[0548] At least a portion of each of the elastic connecting portions 25-1 to 25-4 can be disposed in the hole 41B through the opening of the hole 41B.

[0549] For example, at least a portion of the coupling portion 60B may be disposed within the hole 41B, and an outer surface of the extension portion 41A formed by the hole 41B may face at least a portion of the coupling portion.

[0550] For example, the shape of hole 41B viewed from above may be semicircular or semi-elliptical, but is not limited thereto, and in other embodiments, the shape of the hole viewed from above may be a polygon such as a square or a triangle.

[0551] For example, when compared with FIGS. 18a and 18b, the extension part 41A can reduce the separation distance between the body 252-1 and the connecting elastic parts 25-1 to 25-4, and thus the first damper 310 can be easily applied to the body 252-1 and the connecting elastic parts 25-1 to 25-4.

[0552] For example, the separation distance d1 between the extension part 41A and the coupling part 60A may be smaller than the separation distance d2 between the extension part 41A and the connecting part 60B (d1 < d2). Also, for example, the separation distance d1 between the extension part 41A and the coupling part 60A may be smaller than the widths W1, W2, and W3 of the connecting part 60B. This is for easily applying the first damper 310 to the body 252-1 and the connecting elastic parts 25-1 to 25-4. For example, d1 can be the maximum separation distance between the extension part 41A and the coupling part 60A.

[0553] In other embodiments, the separation distance between the extension part 41A and the coupling part 60A may be the same as or greater than the separation distance between the extension part 41A and the connecting part 60B. Or, the separation distance between the extension part 41A and the coupling part 60A may be the same as or greater than the width of the connecting part 60B.

[0554] FIG. 20a shows a modified example 25-1A of the connecting elastic part 25-1 in FIG. 18b.

[0555] In FIG. 20a, the same reference numerals as in FIGS. 18a and 18b indicate the same configurations, and the descriptions of FIGS. 18a and 18b can be applied or quasi-applied to the same configurations. Although FIG. 20a shows a single connecting elastic part, the description thereof can be similarly applied to the other three connecting elastic parts.

[0556] Referring to FIG. 20a, the connection elastic part 25-1A may include a coupling part 60A1 and a connecting part 60B1. Compared with the connection elastic part 25-1 of FIG. 18b, the connecting part 60B1 of the connection elastic part 25-1A of FIG. 20a may include the first and second connecting parts 61 and 62, and the third connecting part 653 may be omitted. The coupling part 60A1 may be provided at a portion where the first and second connecting parts 61 and 62 meet. For example, the hole 250a may be formed at a portion where the first and second connecting parts 61 and 62 meet. The circuit board 250 may include the escape part 125A of FIG. 18a, and the description of the escape part 125A of FIG. 18a may be applied or mutatis mutandis to the escape part 125A of FIG. 20a.

[0557] FIG. 20b shows a variation 252-2 of the body 252 of the circuit board 250 of FIG. 20a.

[0558] Referring to FIG. 20b, the fuselage 252-2 of FIG. 20b may include an extension 41A1 extending toward the coupling portion 60A1.

[0559] The extension portion 41A1 may protrude from the connecting outer surface 33-5 toward the connecting elastic portion 25-1A. For example, the extension portion 41A1 may extend or protrude from the connecting outer surface 33-5 toward the coupling portion 60A1.

[0560] One end of the extension portion 41A1 may not have a hole as shown in FIG. 19b, but is not limited to this. In other embodiments, one end of the extension portion may have a groove or hole to increase the contact area with the damper.

[0561] The relationship between the width of the extension 41A1, d1, d2, W1, W2, and W3 described in FIG. 19b can be applied or mutatis mutandis to the embodiment of FIG. 20b.

[0562] FIG. 20c shows a modified example 25-1B of the connecting elastic portion 25-1 of FIG. 18b.

[0563] In Fig. 20c, the same reference numerals as in Fig. 18a and 18b indicate the same components, and the explanations of Fig. 18a and 18b can be applied mutatis mutandis to the same components. Fig. 20c shows a single connecting elastic part, but the explanations therefor can be applied to the other three connecting elastic parts in the same manner.

[0564] 20c, the second connecting portion 62 may be omitted in the connecting elastic part 25-1 of FIG.

[0565] In yet another variant, the first connecting portion 62 in FIG. 18b can be omitted, and the connecting elastic portion according to yet another variant can also include a coupling portion 60A, a second connecting portion 62, and a third connecting portion 63.

[0566] FIG. 20d shows a variation of the fuselage 252 of FIG. 20c. The body 252-1 of Fig. 20d may include the extension 41A of Fig. 19b, and the extension 41A may have a hole 41B formed therein. The description of the extension 41A and the hole 41B of Fig. 19b may be applied or mutatis mutandis to the modified example of Fig. 20d.

[0567] FIG. 20e shows a connecting elastic portion 25-1C according to another embodiment. Referring to FIG. 20e, the elastic connection part 25-1C may include a connection part 60A2 connected to the support members 220-1 to 220-4, and a connection part 60B3 extending from the body 252 and connected to the connection part 60A2.

[0568] For example, the connecting portion 60B3 can extend or protrude from one region of a corner of the fuselage 252. For example, the connecting portion 60B3 can extend from a central region of the corner of the fuselage 252 toward the coupling portion 60A2.

[0569] For example, the connecting portion 60B3 can protrude from the connecting side 33-5.

[0570] For example, the other ends of the support members 220-1 to 220-4 coupled to the coupling portion 60A2 may be positioned outside the connecting portion 60B3.

[0571] For example, the width W31 of the connecting portion 60B3 may gradually decrease from one end of the connecting portion 60B3 toward the other end of the connecting portion 60B3.

[0572] One end of the connecting portion 60B3 may be connected to the body 252 of the circuit board 250, and the other end of the connecting portion 60B3 may be connected to the coupling portion 60A2.

[0573] Also, for example, the width of one end of the connecting portion 60B3 may be larger than the width of the other end of the connecting portion 60B3. This is because, by making the width of one end of the connecting portion 60B3 relatively larger than the width of the other end of the connecting portion 60B3, the connecting elastic portion 25-1C can be stably supported on the body 252 of the circuit board 250, and the elastic force of the connecting elastic portion 25-1C in the optical axis direction can be increased and the elastic force of the connecting elastic portion 25-1C in the direction perpendicular to the optical axis can be decreased, thereby making it possible to stably support a lens with a large diameter.

[0574] 18a to 20b may be disposed to be rotationally symmetrical with respect to the center of the body 252, 252-1 of the circuit board 250. For example, the center of the body 252, 252-1 may be the center of the opening C2 of the circuit board 250 or the optical axis.

[0575] For example, the elastic connection parts shown in FIGS. 18a to 20b may be arranged to be rotationally symmetrical by 90 degrees with respect to the center of the body 252, 252-1 of the circuit board 250.

[0576] The embodiments of Figures 18a to 20e show one connecting elastic part formed at one corner of the body 252, 252-1 of the circuit board 250, but are not limited to this. In other embodiments, two or more connecting elastic parts may be provided at one corner of the body 252, 252-1 of the circuit board 250, and the description of the connecting elastic parts of Figures 18a to 20e may be applied or mutatis mutandis to each connecting elastic part.

[0577] For example, the number of connecting elastic parts may be the same as the number of support members disposed at one corner of the housing, at one corner of the body 252, 252-1.

[0578] For example, an embodiment may include two support members disposed at any one corner of the housing 140, and any one corner of the body may have two connecting elastic portions corresponding to the two support members, and each of the two connecting elastic portions may be coupled to a corresponding one of the two support members.

[0579] FIG. 21a is a partial perspective view of a connecting elastic part 25-1, a body 252 of a circuit board 250, a base 210, a first damper 310, and a second damper 310A according to an embodiment, and FIG. 21b is a cross-sectional view taken along the EF direction of FIG. 21a.

[0580] 21a and 21b, the first damper 310 may be disposed between the body 252 (eg, the escape portion 125A) of the circuit board 250 and the connecting elastic portion 25-1 to connect the two.

[0581] For example, a portion of the first damper 310 may be disposed, attached, or coupled to the body 252 (e.g., the escape portion 125A) of the circuit board 250, and another portion of the first damper 310 may be disposed, attached, or coupled to the connecting elastic portion 25-1.

[0582] For example, the other portion of the first damper 310 may be disposed, attached, or coupled to the third connecting portion 63 .

[0583] Also, for example, another portion of the first damper 310 may be in contact with or attached to a portion of the support member 220-1 adjacent to the hole 250a of the connecting elastic portion 25-1.

[0584] Also, the second damper 310A may be disposed between the connecting elastic part 25-1 and the corner region 212 of the base 210, and may connect the two to each other.

[0585] The second damper 310A may be disposed between the connecting elastic part 25-1 and the step part 212A of the base 210, and may connect the connecting elastic part 25-1 and the step part 212A to each other.

[0586] For example, the second damper 310A may be disposed between the connecting elastic portion 25-1 and the first surface 21A of the step portion 212A of the base 210, and may connect the connecting elastic portion 25-1 and the first surface 21A to each other.

[0587] For example, the second damper 310A may be disposed on the stepped portion 212A of the base 210. For example, the second damper 310A may be disposed on at least one of the first surface 21A and the second surface 21B of the stepped portion 212A.

[0588] Also, for example, the second damper 310A can be disposed on at least one of the third surface 21C and the fourth surface 21D of the step portion 212A.

[0589] 14, the second damper 310A may be disposed on an inner surface of a corner region of the cover member 300 corresponding to or facing the corner region 212 of the base 210. Alternatively, in the lens driving device including the base 210-1 shown in FIG. 14, the second damper 310A may be disposed on an inner surface of the guide portion 218 of the base 210. Here, the second damper 310A may contact the inner surface of the guide portion 218 of the base 210.

[0590] Also, at least one of the first damper 310 and the second damper 310A may be disposed in the hole 250a of the elastic connection part 25-1. The second damper 310A may be disposed to contact the solder 902.

[0591] FIG. 21a explains the connecting elastic part 25-1, but the explanation of the first and second dampers 310, 310A in FIG. 21a and FIG. 221b can be applied or mutatis mutandis to the connecting elastic parts 25-1A, 25-1B, 25-1C according to other embodiments or modified examples.

[0592] FIG. 22a is a partial perspective view of a connecting elastic part 25-1, a body 252-1 of a circuit board 250, a base 210-1, a first damper 310, and a second damper 310A according to an embodiment, and FIG. 22b is a cross-sectional view taken along the GH direction of FIG. 22a.

[0593] 22a and 22b, the first damper 310 may be disposed between the extension portion 41A of the body 252-1 of the circuit board 250 and the connecting elastic portion 25-1.

[0594] For example, a portion of the first damper 310 may be disposed, attached, or coupled to the extension portion 41A of the body 252-1 of the circuit board 250, and another portion of the first damper 310 may be disposed, attached, or coupled to the connecting elastic portion 25-1.

[0595] For example, a portion of the first damper 310 may be disposed, attached, or coupled to a hole 41B of the extension 41A. The first damper 310 may be disposed, attached, or coupled to a side of the extension 41A formed by the hole 41B.

[0596] For example, another portion of the first damper 310 in Fig. 22a may be disposed, attached or coupled to the third connecting portion 63. Also, another portion of the first damper 310 in Fig. 22a may be in contact with or attached to a part of the support member 220-1 adjacent to the hole 250a of the connecting elastic portion 25-1.

[0597] The description of the second damper 310 in Figures 21a and 21b may be applied mutatis mutandis to the second damper 310 in Figures 22a and 22b. However, the second damper 310 in Figures 22a and 22b may be disposed between the extension 41A and the corner region 212 of the base 210. For example, the second damper 310 in Figures 22a and 22b may be disposed between the extension 41A and the step 212A. Also, for example, the second damper 310 in Figures 22a and 22b may be disposed between at least one of the first surface 21A and the second surface 21B of the step 212A and the lower surface of the extension 41A.

[0598] FIG. 22a describes the connecting elastic part 25-1, but the description of the first and second dampers 310, 310A in FIG. 22a and FIG. 22b can be applied or mutatis mutandis to the connecting elastic parts 25-1A, 25-1B, 25-1C according to other embodiments or modified examples.

[0599] The first and second dampers 310 and 310A can absorb vibrations of the OIS operating portion caused by driving the OIS, thereby making it possible to suppress oscillation of the OIS operating portion.

[0600] For example, the first and second dampers 310, 310A can reduce the gain at the first and second resonant frequencies of the frequency response characteristics due to OIS driving, thereby suppressing oscillation of the OIS operating portion.

[0601] Furthermore, the second dampers 310A are arranged so as to be uniformly distributed between the connecting elastic portion 25-1 and the corner region 212 of the base 210, thereby making it possible to suppress oscillation caused by the OIS drive and to increase the response speed of the OIS drive.

[0602] FIG. 23 is a cross-sectional view of a portion of a body 252 and a connecting elastic part 25-1 of a circuit board 250 according to an embodiment.

[0603] The body 252 of the circuit board 250 may include a first conductive layer 59-1 disposed on the top surface 21 of the base 210, and a second conductive layer 59-2 disposed on the first conductive layer 59-1.

[0604] The body 252 may also include a first insulating layer 58-1 disposed between the first conductive layer 59-1 and the second conductive layer 59-2 to electrically isolate the first conductive layer 59-1 and the second conductive layer 59-2.

[0605] Body 252 may also include a second insulating layer 58-2 disposed on second conductive layer 59-2, and a third insulating layer 58-3 disposed below first conductive layer 59-1.

[0606] The first conductive layer 59-1 may include a first metal, and the second conductive layer 59-2 may include a second metal, for example, the first metal and the second metal may be different metals.

[0607] For example, the first metal can include at least one of copper (Cu), gold (Au), silver (Ag), or nickel (Ni), and the second metal can be, for example, an alloy including at least one of the first metals, such as a copper alloy.

[0608] In other embodiments, the first metal and the second metal may be formed from the same material.

[0609] Each of the first to third insulating layers 58-1 to 58-3 may be made of an insulating material, for example, polyimide or a coverlay.

[0610] For example, the connecting elastic portion 25-1 may be a portion of the first conductive layer 59-1 of the body 252 that extends or protrudes from the body 252.

[0611] For example, the connecting elastic portion 25-1 may include a 1-1 conductive layer 59-1A, and the 1-1 conductive layer 59-1A may be a portion of the first conductive layer 59-1 of the body 252 that extends or protrudes from the body 252.

[0612] For example, the elastic connection part 25-1 may include a first insulating layer 58-1A disposed on the first conductive layer 59-1A. The first insulating layer 58-1A may be a portion of the first insulating layer 58-1 that extends or protrudes from the body 252.

[0613] Since a portion of the first conductive layer 59-1 serves as the elastic connection portion 25-1, the first conductive layer 59-1 may be made of an electrically conductive material that can serve as an elastic member.

[0614] For example, the first conductive layer 59-1 may be made of the same material as the upper elastic member 150 (or / and the lower elastic member 160).

[0615] For example, the 1-1 conductive layer 59-1A may be made of the same material as the upper elastic member 150 (or / and the lower elastic member 150).

[0616] For example, each of the lower surface and the upper surface of the 1-1 conductive layer 59-1A may be located lower than the lower surface of the second conductive layer 59-2 of the body 252.

[0617] For example, with respect to the lower surface of the body 252, the height H11 of the lower surface of the 1-1 conductive layer 59-1A may be smaller than the height H12 of the lower surface of the second conductive layer 59-2 of the body 252 (H11 <H12)。

[0618] The circuit board 250 may include a hole 250a penetrating the 1-1 conductive layer 59-1A and the 1-1 insulating layer 58-1A.

[0619] The other end of the support member (eg, 220-1) can be coupled to the 1-1 conductive layer 59-1A through the hole 250a by the solder 902.

[0620] For example, the other end of the support member (e.g., 220-1) may be coupled to the lower surface of the 1-1 conductive layer 59-1A through the hole 250a by the solder 902. In another embodiment, the 1-1 insulating layer 58-1A may be omitted, and the solder may be disposed on the upper surface of the 1-1 conductive layer 59-1A, and the 1-1 conductive layer 59-1A and the support member 220-1 may be coupled to each other by the solder. In this case, a portion of the third insulating layer 58-3 may be disposed under the 1-1 conductive layer 59-1A.

[0621] At least one of the first conductive layer 59-1 and the second conductive layer 59-2 of the body 252 may include a circuit pattern, a wiring, or a conductive pattern.

[0622] 23, the 1-1 conductive layer 59-1A and the first conductive layer 59-1 of the body 252 may be electrically connected to each other. Also, the first conductive layer 59-1 and the second conductive layer 59-2 of the body 252 may be electrically connected to each other through a via or a contact via. For example, the via or the contact via may penetrate the first insulating layer to electrically connect the first conductive layer 59-1 and the second conductive layer 59-2.

[0623] The extension 41A of the body 252-1 of Fig. 19b and the extension 41A1 of the body 252-2 of Fig. 20b may have the same configuration as the body 252 described above. For example, each of the extensions 41A and 41A1 may include first and second conductive layers 59-1 and 59-2.
