Description

Technical Field

[0001] The embodiments relate to lens driving devices and camera devices and optical devices, each including a lens driving device. Background Technology

[0002] It is difficult to apply the technology of voice coil motors (VCMs) used in existing general camera modules to ultra-small, low-power camera modules, and therefore, research on this topic has been actively conducted.

[0003] The demand for and production of electronic products such as smartphones and mobile phones equipped with cameras have increased. Cameras for mobile phones are trending towards higher resolution and miniaturization. Consequently, actuators have also been miniaturized, increased in diameter, and made multifunctional. To achieve high-resolution cameras for mobile phones, it is necessary to improve the performance of cameras for mobile phones and their additional functions, such as autofocus, image stabilization, and zoom. Summary of the Invention

[0004] Technical issues

[0005] The embodiments provide lens driving devices, camera devices, and optical devices that can prevent or suppress the breakage of support members and ensure the reliability of OIS operation.

[0006] means for solving problems

[0007] The lens driving device according to the embodiment includes a base, an elastic member connected to the base, a circuit board disposed on the base, a housing disposed on the circuit board, a coil frame disposed in the housing, an upper elastic member connecting both the upper portion of the coil frame and the upper portion of the housing, and a support member having a first end connected to the upper elastic member, wherein the elastic member includes a first connector connected to the base and electrically connected to the circuit board, a second connector connected to a second end of the support member, and a connector connecting the first connector to the second connector.

[0008] The second end of the support member may be movable and positioned below the circuit board. The connector may include at least one bent portion.

[0009] The width of the connector can be less than the length of the first connector in the direction perpendicular to the optical axis and the diameter of the second connector, and the width of the connector can be the length of the connector in the direction perpendicular to the direction in which the connector extends.

[0010] The base may include a clearance portion configured to avoid spatial interference with the second connector and the support member. The base may include a groove for the first connector to be disposed therein, and the base may include an inclined surface disposed at the bottom surface of the groove of the base and at a position corresponding to the first end of the connector that is connected to the first connector.

[0011] The lens driving device may further include: a first magnet disposed on the housing; a first coil disposed on a coil holder and configured to move the coil holder along the optical axis through interaction with the first magnet; and a second coil configured to move the housing in a direction perpendicular to the optical axis through interaction with the first magnet. The second coil may be positioned closer to the elastic member than to the upper elastic member. The elastic modulus of the elastic member may be higher than that of the upper elastic member.

[0012] The first connector may include a first connection region connected to a first region of the base and a second connection region connected to a second region of the base, and the connector may include a first connector connected to the first connection region and a second connector connected to the second connection region. The connector may include a third connector that connects portions of the first and second connectors to each other to the second connector. The elastic member may be a leaf spring. A first end of a support member may be attached to the upper elastic member via solder or conductive adhesive, and a second end of the support member may be attached to the second connector via solder or conductive adhesive. The circuit board may include pads attached to the first connector via solder or conductive adhesive.

[0013] According to another embodiment, a lens driving device includes a base, an elastic member connected to the base, a circuit board disposed on the base, a housing disposed on the circuit board, a coil frame disposed in the housing, a first magnet disposed in the housing, a first coil disposed on the coil frame, an upper elastic member connecting both the upper portion of the coil frame and the upper portion of the housing, a support member connecting the upper elastic member to the elastic member, and a second coil oriented to face the first magnet in the optical axis direction and configured to move the housing by interacting with the first magnet, wherein the second coil is positioned closer to the elastic member than to the upper elastic member, and one end of the support member connected to the elastic member is movable.

[0014] Invention Effects

[0015] As is evident from the above description, the implementation is configured such that the lower end of the support member that supports the OIS moving unit is connected or coupled to the elastic member, so that even when a heavy lens module is installed, the impact or stress applied to the support member can be dispersed by the elastic member.

[0016] Furthermore, the implementation method can prevent or suppress the breakage of the support components and ensure the reliability of OIS operation.

[0017] Furthermore, since this embodiment is constructed such that the lower end of the support member can move up and down with the aid of an elastic member, the breakage of the OIS moving unit caused by external impact can be reduced.

[0018] Furthermore, since this embodiment is constructed such that both the upper and lower ends of the support member are movable, the degree of tilting or the tilting can be reduced or suppressed when the OIS moving unit tilts. Attached Figure Description

[0053] In the following description of the embodiments, the embodiments will be clearly explained by reference to the accompanying drawings. In the following description of the embodiments, it will be understood that when an element such as a layer (film), region, pattern, or structure is referred to as being "above" or "below" another element, the element may be located "directly" above or below the other element, or may be formed "indirectly" such that intermediate elements may also be present. Furthermore, it will be understood that the criteria for "above" or "below" are determined based on the accompanying drawings.

[0054] In the accompanying drawings, for clarity and convenience, layer dimensions may be exaggerated, omitted, or shown schematically. Additionally, the dimensions of constituent elements may not accurately reflect their actual dimensions. Throughout the drawings, the same reference numerals will be used to refer to the same or similar parts as much as possible.

[0055] In the following description, the lens driving device according to an embodiment will be described with reference to the accompanying drawings. For ease of description, although the lens driving device according to the embodiment is described using a Cartesian coordinate system (x, y, z), the lens driving device may also be described using other coordinate systems, and the embodiment is not limited thereto. In the various drawings, the X-axis direction and the Y-axis direction refer to directions perpendicular to the optical axis, i.e., the Z-axis. The Z-axis direction, which is the direction of the optical axis, can be defined as "one of the first direction, the second direction, and the third direction", the X-axis direction can be defined as "the other one of the first direction to the third direction", and the Y-axis direction can be defined as "the remaining one of the first direction to the third direction".

[0056] The X-axis (or Y-axis) can be referred to as the "first horizontal axis," and the direction of the X-axis (or Y-axis) can be referred to as the "first horizontal direction." Furthermore, the Y-axis (or X-axis) can be referred to as the "second horizontal axis," and the direction of the Y-axis (or X-axis) can be referred to as the "second horizontal direction." For example, the direction of the optical axis can be the direction of the optical axis or a direction parallel to the optical axis. Additionally, the direction of the first axis can be a direction parallel to the first axis, and the direction of the second axis can be a direction parallel to the second axis.

[0057] For example, the optical axis can be the optical axis of a lens mounted on the lens barrel. Alternatively, the optical axis can be an axis perpendicular to the imaging area (or sensor surface) of the image sensor and extending through the center of the imaging area. In the following text, the term "terminal" may be used interchangeably with "pad," "electrode," or "conductive layer." Furthermore, the term "opening" may be used interchangeably with "cavity" or "hole."

[0058] In the following text, the lens drive device may be alternatively referred to as a lens moving unit, voice coil motor (VCM), actuator, or lens moving device. The term "coil" may be used interchangeably with "coil unit," and the term "elastic member" may be used interchangeably with "elastic unit" or "spring." Furthermore, the term "camera device" may be used interchangeably with "camera," "actuator," "camera module," "imager," or "imaging device."

[0059] The lens driving device according to an embodiment of the present invention is capable of performing an "autofocus function". Here, the "autofocus function" is used to automatically focus the image of the object onto the surface of the image sensor.

[0060] Furthermore, the lens driving device according to the embodiment can perform a "shake correction" function. Here, the "shake correction" function can be used to prevent the outline of the captured image from becoming blurred due to vibrations caused by the user's hand shaking when capturing a still image.

[0062] Reference Figures 1 to 18b The lens driving device 100 may include a fixing unit, an AF moving unit, and an OIS moving unit. Furthermore, the lens driving device 100 may include a driving unit configured to move the AF moving unit and / or the OIS moving unit.

[0063] The lens drive device 100 may include elastic members 150 and 160 that connect the moving unit to the fixed unit, and a support member 220 connected to the elastic members 150 and 160 and configured to support the OIS moving unit relative to the fixed unit.

[0064] The fixing unit can be a component that is stationary relative to AF operation or OIS (optical image stabilization) operation. The fixing unit can be a part or component that cannot move along the optical axis or in a direction perpendicular to the optical axis.

[0065] The AF shift unit can be a component or element that can move along the optical axis during autofocus operation. The OIS shift unit can be a component or element that can move in a direction perpendicular to the optical axis for image stabilization.

[0066] The fixing unit may include at least one of the base 210 or the cover member 300.

[0067] The AF moving unit may include a coil holder 110. The AF moving unit may include components connected to the coil holder 110. The OIS moving unit may include an AF moving unit and a housing 140. The OIS moving unit may include components connected to the housing 140.

[0068] The driving unit may include a first driving unit comprising a first coil 120 and a first magnet 130 for movement of the AF (Action Focusing) moving unit. Furthermore, the driving unit may include a second driving unit comprising a first magnet 130 and a second coil 230 for movement of the OIS (Optical Interference Focusing) moving unit. The first magnet 130 may be a shared magnet for both AF and OIS operations. In another embodiment, the first magnet 130 may be used for AF operations and may be provided with a separate magnet configured to interact with the second coil 230 for OIS operations.

[0069] The elastic member may include an upper elastic member 150 and an elastic member 60. The elastic member may also include a lower elastic member 160.

[0070] The lens drive device 100 may include a first position sensor 170 for AF feedback operation. Furthermore, the lens drive device 100 may include a circuit board 190 electrically connected to the first position sensor. The lens drive device 100 may include a second magnet 180. The lens drive device may include a third magnet 185. The lens drive device 100 may also include a capacitor 195 disposed on or mounted on the circuit board 190.

[0071] To perform feedback operations for shaky hand correction, the lens drive device 100 may include a second position sensor 240. The lens drive device 100 may include a circuit board 250 electrically connected to the second coil 230.

[0072] The coil holder 110 is movable along the optical axis. The coil holder 110 may be disposed in the housing 140. The coil holder 110 may be disposed in the cover member 300. For example, the coil holder 110 is movable along the optical axis OA or a first direction (e.g., the Z-axis direction) by means of the electromagnetic interaction between the first coil 120 and the first magnet 130.

[0073] Reference Figures 3a to 3bThe coil holder 110 may have an opening 102 for mounting a lens or lens barrel therein. For example, the opening 102 in the coil holder 110 may be a through hole formed through the coil holder 110 along the optical axis, and the opening 102 may have a circular, elliptical, or polygonal shape, but is not limited thereto. The opening 102 in the coil holder 110 may correspond to, face, or overlap with the opening 303 in the cover member 300 in the optical axis direction.

[0074] A lens can be directly disposed within the opening 102 in the coil holder 110. In another embodiment, a lens barrel for mounting or connecting at least one lens can be connected to or mounted in the opening 102 of the coil holder 110. The lens or lens barrel can be connected to the inner peripheral surface of the coil holder 110. Alternatively, the outer peripheral surface of the lens barrel (or lens) and the inner peripheral surface of the coil holder 110 can be threaded to engage with each other.

[0075] The coil frame 110 may include first side portions 110b1 to 110b4 spaced apart from each other and second side portions 110c1 to 110c4 spaced apart from each other. Each of the second side portions 110c1 to 110c4 can connect two adjacent first side portions to each other. For example, the horizontal or lateral length of each of the first side portions 110b1 to 110b4 of the coil frame 110 may be different from the horizontal or lateral length of each of the second side portions 110c1 to 110c4 of the coil frame 110.

[0076] The coil holder 110 may include a protrusion 115 disposed or formed on its outer surface. The protrusion 115 may be disposed on at least one of the side portions 110b1 to 110b4 and 110c1 to 110c4 of the coil holder 110. The protrusion 115 may project in a direction parallel to a line extending through the center of the opening 102 in the coil holder 110 and parallel to the optical axis. For example, the protrusion 115 may project in a direction perpendicular to the outer surface of the side portions 110b1 to 110b4 and 110c1 to 110c4.

[0077] The protrusion 115 of the coil holder 110 corresponds to the groove 25a of the housing 140, and the protrusion 115 of the coil holder 110 can be inserted into or disposed in the groove 25a in the housing 140 so that the coil holder 110 suppresses or prevents the rotation of the coil holder 110 around the optical axis from exceeding a predetermined range.

[0078] Furthermore, the protrusion 115 can be used as a stop to minimize or prevent direct collision between the lower surface of the coil holder 110 and the base 210, the second coil 230, or the circuit board 250, even when the coil holder 110 moves beyond a predetermined range along the optical axis direction (e.g., along the direction from the upper elastic member 150 toward the lower elastic member 160) due to external impacts, etc.

[0079] The coil holder 110 may have a first clearance groove 112a formed in its upper surface to avoid spatial interference with the first frame connector 153 of the upper resilient member 150. For example, the first clearance groove 112a may be provided on at least one of the second side portions 110c1 to 110c4 of the coil holder 110. In another embodiment, the first clearance groove 112a may be provided on at least one of the first side portions 110b1 to 110b4 of the coil holder 110.

[0080] The upper surface of the coil holder 110 may be provided with a guide portion 111 for guiding the installation position of the upper elastic member 150. For example... Figure 3a As illustrated, for example, the guide portion 111 of the coil holder 110 may be disposed in the first clearance groove 112a to guide the path along which the first frame connector 153 of the upper elastic member 150 extends. For example, the guide portion 111 may protrude from the bottom surface of the first clearance groove 112a along the optical axis. The lens drive device 100 may include a damper (not shown) or shock absorber disposed between the guide portion 111 of the coil holder 110 and the frame connector 153, and connected to or in contact with both the guide portion 111 of the coil holder 110 and the frame connector 153.

[0081] The coil holder 110 may include a stop 116 protruding from the upper surface of the coil holder 110.

[0082] The stop portion 116 of the coil holder 110 can be used to prevent the upper surface of the coil holder 110 from directly colliding with the inner side of the upper plate of the cover member 300, even when the coil holder 110 moves beyond a specified range due to external impact or the like while the coil holder 110 is moving in the first direction to perform the autofocus function.

[0083] The coil holder 110 may include a first connector 113 intended to be connected and secured to the upper resilient member 150. Figure 3aEach of the first connectors 113 in the coil holder 110 shown may be configured to have a protruding shape. In another embodiment, each of the first connectors 113 in the coil holder 110 may be configured to have a grooved or flat surface. The coil holder 110 may include a second connector 117 that is coupled to and secured to the lower resilient member 160. Figure 3b In one embodiment, the second connector 117 of the coil holder 110 may have the form of a protrusion. In another embodiment, the second connector of the coil holder 110 may have the form of a groove or a flat surface.

[0084] The outer surface of the coil holder 110 may be provided with a seating groove 105 for the first coil 120 to be seated, inserted, or disposed therein. The seating groove 105 may be in the form of a groove recessed from the outer surface of the first side portion 110b-1 and the second side portion 110b-2 of the coil holder 110, and may have a shape corresponding to the shape of the first coil 120 or the shape of a closed curve (e.g., the shape of a loop).

[0085] When the first coil 120 is connected to the lower elastic members 160-1 to 160-2, in order to suppress the separation of the first coil 120 and guide the two ends of the first coil 120, the lower surfaces of the two first side portions or the two second side portions of the coil holder 110 positioned opposite to the coil holder 110 may have one or more guide grooves 116a and 116b formed therein.

[0086] The coil holder 110 may include a seating groove 180a in which a second magnet 180 of the coil holder 110 is seated, inserted, or disposed. The seating groove 180a may be recessed from the outer surface of the coil holder 110. The coil holder 110 may include a seating groove 185a in which a third magnet 185 is seated, inserted, fixed, or disposed. The seating groove 185a may have a structure that is recessed from the outer surface of the coil holder 110. The seating groove 185a may have an opening that is open at at least one of the upper or lower surfaces of the coil holder 110.

[0087] For example, each of the seating recesses 180a and 185a in the coil holder 110 may have at least one opening that is open at least one of the upper or lower surfaces of the coil holder 110. In another embodiment, each of the seating recesses 180a and 185a may not have at least one opening that is open at least one of the upper or lower surfaces of the coil holder 110.

[0088] The mounting grooves 180a and 185a in the coil holder 110 can be positioned above the mounting groove 105 in which the first coil 120 is disposed, and can be connected to or abut against the mounting groove 105. In another embodiment, the mounting grooves 180a and 185a and the mounting groove 105 can be spaced apart from each other.

[0089] For example, the seating recesses 180a and 185a may be provided on two first side portions (e.g., 110b1 and 110b3) of the coil holder 110 that are positioned facing each other or opposite each other.

[0090] Since the second magnet 180 and the third magnet 185 are disposed in the sitting grooves 180a and 185a in two first side portions (e.g., 110b1 and 110b3) formed in the coil frame 110 and positioned opposite each other, weight balance between the second magnet 180 and the third magnet 185 can be achieved. Furthermore, the influence on the AF driving force caused by the magnetic field interference between the first magnet 130 and the second magnet 180 can be offset by the influence on the AF driving force caused by the magnetic field interference between the first magnet 130 and the third magnet 185, thereby improving the accuracy of AF operation.

[0091] The coil holder 110 may have threads 11 on its inner circumferential surface for connection to a lens or lens barrel. The threads 11 may be formed in the inner circumferential surface of the coil holder 110 while it is held by a clamp or similar device. The upper surface of the coil holder 110 may have clamping grooves 15a and 15b formed therein. For example, clamping grooves 15a and 15b may be provided at two first side portions (e.g., 110b2 and 110b4) of the coil holder 110 positioned opposite each other. In another embodiment, clamping grooves may be provided at the upper surfaces of two second side portions of the coil holder 110 positioned opposite each other. The clamping grooves 15a and 15b can be used as foreign object collectors configured to collect foreign objects. In another embodiment, the threaded portion on the inner circumferential surface of the coil holder 110 may be omitted, and the clamping grooves 15a and 15b may be omitted.

[0092] The first coil 120 can be disposed on, connected to or fixed to the coil frame 110. For example, the first coil 120 can be disposed on or connected to the outer surface of the coil frame 110.

[0093] The first coil 120 may be disposed below the second magnet 180 and the third magnet 185. For example, the first coil 120 may be disposed below the protrusion 115 of the coil holder 110. For example, at least a portion of the first coil 120 may not overlap with the second magnet 180 and the third magnet 185 in a direction perpendicular to the optical axis. In another embodiment, at least a portion of the first coil 120 may overlap with the second magnet 180 and the third magnet 185 in a direction perpendicular to the optical axis.

[0094] For example, the first coil 120 can be disposed in the sitting groove 105 in the coil holder 110, the second magnet 180 can be inserted into or disposed in the sitting groove 180a in the coil holder 110, and the third magnet 185 can be inserted into or disposed in the sitting groove 185a in the coil holder 110.

[0095] Each of the second magnet 180 and the third magnet 185 disposed on the coil holder 110 may not overlap with the first coil 120 in the direction of the optical axis OA. In another embodiment, each of the second magnet 180 and the third magnet 185 disposed on the coil holder 110 may abut against the first coil 120, or may overlap with the first coil 120 in a direction perpendicular to the optical axis.

[0096] For example, when viewed from above or along the optical axis, the first coil 120 may be positioned outside the second magnet 180 (or the third magnet 185). In another embodiment, when viewed from above or along the optical axis, the first coil 120 may be positioned inside the second magnet 180 (or the third magnet 185).

[0097] The first coil 120 can be wound around the outer surface of the coil frame 110 in the direction of rotation about the optical axis OA. The first coil 120 can be directly wound around the outer surface of the coil frame 110. The first coil 120 can be wound around the outer surface of the coil frame 110 about the optical axis OA, which is the axis of rotation.

[0098] In another embodiment, the first coil 120 may be coupled to a coil ring coupled to the coil holder 110. In yet another embodiment, the first coil 120 may be in the form of a coil block and may be coupled or fixed to the outer surface of the coil holder 110 via adhesive.

[0099] In another embodiment, the first coil may be in the form of a coil loop wound around an axis perpendicular to the optical axis or perpendicular to the outer surface of the coil holder 110.

[0100] A power signal or a drive signal can be supplied to the coil 120. The power signal or drive signal supplied to the first coil 120 can be a DC signal, an AC signal, or a signal containing both DC and AC components, and can be voltage-type or current-type.

[0101] When a drive signal (e.g., drive current) is supplied to the first coil 120, an electromagnetic force can be generated by the electromagnetic interaction with the first magnet 130, thereby causing the coil frame 110 to move along the direction of the optical axis OA by means of the generated electromagnetic force.

[0102] At the initial position of the AF moving unit, the coil holder 110 can move upward or downward, which is referred to as bidirectional drive of the AF moving unit. Alternatively, at the initial position of the AF moving unit, the coil holder 110 can move upward, which is referred to as unidirectional drive of the AF moving unit.

[0103] At the initial position of the AF moving unit, the first coil 120 can be configured to correspond to, face, or overlap with the first magnet 130 disposed on the housing 140 in a direction parallel to a line perpendicular to the optical axis OA and extending through the optical axis.

[0104] For example, the AF moving unit may include components (e.g., a first coil 120, a second magnet 180, and a third magnet 185) connected to the coil holder 110.

[0105] The initial position of the AF moving unit can be the initial position of the AF moving unit when no power is applied to the first coil 1120. In other words, the initial position of the AF moving unit can be the position where the AF moving unit is located due to the elastic deformation of the upper elastic member 150 and the lower elastic member 160 solely due to the weight of the AF moving unit. Furthermore, the initial position of the coil frame 110 can be the position where the AF moving unit is located when gravity acts in the direction from the coil frame 110 to the base 210, or when gravity acts in the direction from the base 210 to the coil frame 110.

[0106] Since the second magnet 180 provides a magnetic field, which is detected by the first position sensor 170, the second magnet 180 can be referred to as a sensing magnet. The third magnet 185, which can be referred to as a "balancing member," "weight balancing member," "weight member," or "balancing magnet," counteracts the influence of the magnetic field of the sensing magnet 180 and establishes weight balance relative to the sensing magnet 180. In another embodiment, the lens driving device 100 may include a "balancing member" or "weight member" as a non-magnetic body instead of the third magnet 185 to achieve weight balance.

[0107] At the initial position of the coil holder 110, the second magnet 180 may be positioned to correspond with, face, or overlap with the first position sensor 170 in a direction perpendicular to the optical axis OA or in a direction parallel to a line perpendicular to the optical axis and extending through the optical axis. In another embodiment, at the initial position of the coil holder 110, the second magnet 180 may be positioned not to correspond with, face, or overlap with the first position sensor 170 in a direction perpendicular to the optical axis OA or in a direction parallel to a line perpendicular to the optical axis and extending through the optical axis.

[0108] The second magnet 180 facing the first position sensor 170 may be exposed from the seating recess 180a at a portion of one surface of the second magnet 180. In another embodiment, the second magnet 180 facing the first position sensor 170 may not be exposed from the seating recess 180a at a portion of one surface of the second magnet 180.

[0109] For example, each of the second magnet 180 and the third magnet 185 disposed on the coil frame 110 can be configured such that the interface between the N pole and the S pole is parallel to a direction perpendicular to the optical axis OA. For example, each surface of the second magnet 180 and the third magnet 185 facing the first position sensor 170 can be divided into an N pole and an S pole. In another embodiment, each of the second magnet 180 and the third magnet 185 disposed on the coil frame 110 can be configured such that the interface surface between the N pole and the S pole is parallel to the optical axis OA.

[0110] For example, each of the second magnet 180 and the third magnet 185 may be a unipolar magnetized magnet or a bipolar magnetized magnet having one N pole and one S pole. In another embodiment, each of the second magnet 180 and the third magnet 185 may be a bipolar magnetized magnet or a quadrupole magnetized magnet having two N poles and two S poles.

[0111] Each of the second magnet 180 and the third magnet 185 may include a first magnet portion 17a, a second magnet portion 17b, and a partition wall 17c disposed between the first magnet portion 17a and the second magnet portion 17b. Here, the partition wall 17c may also be alternatively referred to as a "non-magnetic partition wall." The first magnet portion 17a may include an N pole, a S pole, and a first interface portion located between the N pole and the S pole. The first interface portion may be a portion of a region that is substantially non-magnetic and has almost no polarity, and the first interface portion may be a portion that is naturally formed to form a magnet consisting of an N pole and an S pole. The second magnet portion 17b may include an N pole, an S pole, and a second interface surface located between the N pole and the S pole. The second interface portion may be a portion of a region that is substantially non-magnetic and has almost no polarity, and the second interface portion may be a portion that is naturally formed to form a magnet consisting of an N pole and an S pole. The partition wall 17c may separate or isolate the first magnet portion 17a and the second magnet portion 17b from each other, and the partition wall 17c may be a portion that is substantially non-magnetic or non-polar. For example, the partition wall can be a non-magnetic material, air, etc. A non-magnetic partition wall can be referred to as a "neutral zone" or "neutral region".

[0112] The partition wall 17c may be an artificially formed portion 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 interface portion (or the width of the second interface portion). Here, the width of the partition wall 17c may be the length of the partition wall 17c in the direction from the first magnet portion 17a toward the second magnet portion 17b. The width of the first interface portion (or the second interface portion) may be equal to the length of each of the first magnet portion 17a and the second magnet portion 17b from the N pole toward the S pole.

[0113] The second magnet 180 can move along the optical axis together with the coil frame 110. The first position sensor 170 can detect the strength or force of the magnetic field of the second magnet 180 moving along the optical axis and can output an output signal corresponding to the detection result.

[0114] For example, the strength or force of the magnetic field detected by the first position sensor 170 can change based on the displacement of the coil holder 110 in the optical axis direction. Therefore, the first position sensor 170 can output an output signal proportional to the detected magnetic field strength. The output from the first position sensor 170 can be used to detect the displacement of the coil holder 110 in the optical axis direction.

[0115] In another embodiment, the first position sensor 170 may be disposed on the coil holder 110, and the second magnet 180 may be disposed on the housing 140. Alternatively, the first position sensor 170 may be disposed on the coil holder 110 to detect the magnetic field strength of the first magnet 130, and the second magnet 180 and the third magnet 185 may be omitted.

[0116] The housing 140 can be disposed within the cover member 300. The housing 140 can accommodate the coil holder 110 therein. The housing 140 can be disposed on the upper portion of the base 210. The housing 140 can be disposed on the circuit member 231 or the circuit board 250.

[0117] The housing 140 may be spaced apart from the fixing unit. For example, the housing 140 may be spaced apart from the cover member 300, the circuit member 231, the circuit board 250, and / or the base 210. The housing 140 may support the first magnet 130, the first position sensor 170, and the circuit board 190.

[0118] Reference Figure 4a and Figure 4b The housing 140 can be constructed as a hollow cylinder. For example, the housing 140 can have a polygonal (e.g., rectangular or octagonal) or circular opening 201 or cavity. The opening 201 in the housing 140 can be a through hole formed through the housing 140 along the optical axis.

[0119] The housing 140 may include a side portion 141 and a corner portion 142. For example, the side portion 141 may include a plurality of side portions 141-1 to 141-4. The corner portion 142 may include a plurality of corner portions 142-1 to 142-4.

[0120] For example, housing 140 may include first side portions 141-1 to fourth side portions 141-4 spaced apart from each other and first corner portions 142-1 to fourth corner portions 142-4 spaced apart from each other. Each corner portion of corner portion 142 of housing 140 may be disposed or positioned between two adjacent side portions 141-1 and 141-2, 141-2 and 141-3, 141-3 and 141-4, and 141-4 and 141-1, so as to connect side portions 141-1 to 141-4 to each other.

[0121] For example, corner portions 142 may be located at corners or edges of housing 140. For example, housing 140 may have four side portions and four corner portions. In another embodiment, housing 140 may have five or more side portions (or corner portions).

[0122] The side portions of the housing 140 may correspond to the side plates 302 of the cover member 300. Each of the side portions 141-1 to 141-4 of the housing 140 may be configured to be parallel to a corresponding side plate of the cover member 300.

[0123] For example, side portions 141-1 to 141-4 of the housing 140 may respectively face or correspond to the first side portions 110b1 to 110b4 of the coil frame 110, and corner portions 142-1 to 142-4 of the housing 140 may respectively face or correspond to the second side portions 110c1 to 110c4 of the coil frame 110. A first magnet 130 may be disposed on the housing 140. For example, the first magnet 130 may be disposed on at least one corner portion of the corner portions 142-1 to 142-4 of the housing 140. In another embodiment, the first magnet 130 may be disposed on at least one side portion of the side portions 141-1 to 141-4 of the housing 140.

[0124] For example, the housing 140 may include a seating portion 141a (or receiving portion) disposed or formed on a corner or corner portion 142 of the housing 140. The first magnet 130 may be disposed on the seating portion 141a of the housing 140.

[0125] For example, the seating portion 141a of the housing 140 may be disposed at the lower portion or lower end of at least one of the corner portions 142-1 to 142-4 of the housing 140. For example, the seating portion 141a in the housing 140 may be formed in the inner portion of the lower portion or lower end of each of the four corner portions 142-1 to 142-4. Each seating portion 141a in the housing 140 may include a groove or recess having a shape corresponding to the first magnet 130.

[0126] A first opening may be formed in the lower surface of the mounting portion 141a in the housing 140 facing the second coil 230 to facilitate the mounting of the first magnet 130. The lower surface 11c of the first magnet 130, which is fixed to or disposed on the mounting portion 141a of the housing 140, may be exposed through the first opening in the mounting portion 141a.

[0127] In another embodiment, the seating portion 141a may include a second opening formed on the side surface of the seating portion 141a of the housing 140 facing the first coil 120. Here, the first surface 11a of the first magnet 130 fixed to the seating portion 141a in the housing 140 or disposed in the seating portion 141a in the housing 140 may be exposed through the second opening in the seating portion 141a.

[0128] The housing 140 may have clearance grooves 41 formed in the upper surface of each corner portion to avoid spatial interference with at least a portion of the first frame connector 153 of the upper resilient member 150. For example, the clearance grooves 41 in the housing 140 may be recessed from the upper surface of the housing 140. For example, the clearance grooves 41 may be positioned closer to the center of the housing 140 than the stop 145 or the adhesive injection hole 146. For example, the clearance grooves 41 may be positioned further inward than the stop 145 of the housing 140 in a direction toward the center of the housing 140, and the adhesive injection hole 146 may be positioned opposite the clearance grooves 41 relative to the stop 145.

[0129] The housing 140 may include a recess 25a that corresponds to or faces the protrusion 115 of the coil holder 110. For example, the recess 25a may be provided or formed at at least one of the corner portions 142-1 to 142-4 of the housing 140.

[0130] The recess 25a in the housing 140 can be positioned at the sitting portion 141a in the housing 140. For example, the recess 25a in the housing 140 can be formed in the bottom surface of the clearance recess 41. For example, the bottom surface of the recess 25a can be positioned below the bottom surface of the clearance recess 41, and the sitting recess 141a in the housing 140 can be positioned below the bottom surface of the clearance recess 41. The recess 25a in the housing 140 and the protrusion 115 of the coil holder 110 can be opposite to or overlap each other in the optical axis direction, and the recess 25a in the housing 140 can be used as a stop to prevent the coil holder 110 from moving downward beyond a predetermined range.

[0131] For example, the first magnet 130 can be fixed to the seating portion 141a by means of an adhesive. For example, the housing 140 may include at least one adhesive injection hole 146 through which adhesive is applied to the first magnet 130. For example, the adhesive injection hole 146 may be provided or formed at at least one corner portion 142-1 to 142-4 of the housing 140. In another embodiment, the adhesive injection hole may be provided on at least one side portion 141-1 to 141-4 of the housing 140.

[0132] The adhesive injection hole 146 may be a through hole formed in the optical axis direction through the housing (or corner portions 142-1 to 142-4). For example, the number of adhesive injection holes 146 may be one, two or more. For example, the adhesive injection hole 146 may include two adhesive injection holes 146a and 146b spaced apart from each other.

[0133] The adhesive injection hole 146 can be connected to or communicate with the seating recess 141a in the housing 140, and the adhesive injection hole 146 can expose at least a portion of the first magnet 130 (e.g., at least a portion of the upper surface of the magnet 130). Because the adhesive injection hole 146 exposes at least a portion of the first magnet 130 (e.g., at least a portion of the upper surface of the magnet 130), adhesive can be effectively applied to the first magnet 130, and thus the connection or fixing force between the first magnet 130 and the housing 140 can be improved.

[0134] For example, the housing 140 may have a recess 22A disposed around the adhesive injection hole 146. The recess 22A may be recessed from the upper surface of the housing 140. The adhesive injection hole 146 may be formed in the bottom of the recess 22A. The recess 22A may be used to receive adhesive and allow adhesive to be slowly injected into the adhesive injection hole 146 and thus uniformly applied to the sitting portion 141a.

[0135] The lower surface 11c of the first magnet 130 fixed to the seat portion 141a of the housing 140 or disposed on the seat portion 141a of the housing 140 can be exposed through the second opening in the seat portion 141a.

[0136] The housing 140 may include at least one stop 147a protruding from the outer surface of the side portions 141-1 to 141-4, and the at least one stop 147a may be used to prevent the outer surface of the housing 140 from directly colliding with the side plate of the cover member 300 when the housing 140 moves in a direction perpendicular to the optical axis.

[0137] The housing 140 has a mounting recess 14a (or seating recess) configured to receive a circuit board 190, a mounting recess 14b (or seating recess) configured to receive a position sensor 170, and a mounting recess 14c (or seating recess) configured to receive a capacitor 195. The mounting recess 14a in the housing 140 may be formed in the upper portion or upper end of one of the side portions 141-1 to 141-4 of the housing 140 (e.g., 141-1). In another embodiment, the mounting recess 14a may be provided on a corner portion of the corner portion of the housing 140.

[0138] To facilitate mounting of the circuit board 190, the mounting recess 14a in the housing 140 may have a recessed structure—open at its upper surface and having side and bottom surfaces—and an opening formed in its inner surface to expose the interior of the housing 140. The mounting recess 14a in the housing 140 may have a shape corresponding to or conforming to the shape of the circuit board 190. For example, a mounting recess 14b may be formed in the inner surface of the first side portion 141-1 of the housing 140 and may be connected to the mounting recess 14a.

[0139] The mounting groove 14c in the housing 140 may be formed in a portion of the mounting groove 14b, and a protrusion or bulge may be provided between the mounting groove 14b and the mounting groove 14c to separate or isolate the capacitor 195 from the first position sensor 170. This is done to position the capacitor 195 and the position sensor 170 close to each other and to reduce the path length for the electrical connection between the capacitor 195 and the position sensor 170, thereby reducing noise caused by a long path.

[0140] Capacitor 195 can be disposed or mounted on the first surface 19a of circuit board 190.

[0141] The capacitor 195 may be configured to have a chip shape. 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 alternatively be referred to as a "capacitive element" or a "condenser".

[0142] In another embodiment, the capacitor may be included in the circuit board 190. For example, the circuit board 190 may include a capacitor comprising 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.

[0143] Capacitor 195 can be conductively connected in parallel to the first terminal B1 and the second terminal B2 of circuit board 190, supplying an electrical signal (or drive signal) to position sensor 170 from the outside through the first terminal B1 and the second terminal B2. For example, capacitor 195 can be conductively connected in parallel to the first terminal B1 and the second terminal B2 of circuit board 190. Alternatively, capacitor 195 can be conductively connected in parallel to the terminals of the first position sensor 170, which are conductively connected to the first terminal B1 and the second terminal B2 of circuit board 190.

[0144] For example, one end of capacitor 195 (or the first terminal of capacitor chip) can be conductively connected to the first terminal B1 of circuit board 190, and the other end of capacitor 195 (or the terminal of capacitor chip) can be conductively connected to the second terminal B2 of circuit board 190. Since capacitor 195 is conductively connected to the first terminal B1 and the second terminal B2 of circuit board 190, capacitor 195 can be used as a smoothing circuit to eliminate ripple components contained in the power signals GND and VDD supplied from the outside to the first position sensor 170, and therefore capacitor 195 can supply a stable and consistent power signal to the first position sensor 170.

[0145] Furthermore, since capacitor 195 is conductively connected to the first terminal B1 and the second terminal B2 of circuit board 190, the first position sensor 170 can be protected from externally introduced high-frequency noise, ESD, etc. Additionally, capacitor 195 can prevent overcurrent caused by externally introduced high-frequency noise, ESD, etc., from being applied to the first position sensor 170, and capacitor 195 can prevent the calibration value of the coil frame 110 obtained based on the signal output from the first position sensor 170 from being reset due to overcurrent.

[0146] The mounting recess 14b of the housing 140 may be open at its upper portion to facilitate the mounting of the first position sensor 170, and the mounting recess 14b may have an opening formed in the inner surface of the first side portion 141-1 of the housing 140 to improve the sensitivity of the position sensor 170. The mounting recess 14b in the housing 140 may have a shape corresponding to or conforming to the shape of the first position sensor 170.

[0147] For example, an adhesive component can be used to secure the circuit board 190 in the mounting recess 14a within the housing 140. The adhesive component can be epoxy resin or double-sided adhesive tape.

[0148] The corner portions 142-1 to 142-4 of the housing 140 may each be provided with support members 220A to 220D. The housing 140 may have a hole 147 through which at least a portion of the support member 220 extends. The hole 147 may define the path through which the support member 220 passes. For example, the hole 147 may be provided at the corner portions 142-1 to 142-4 of the housing 140. For example, the housing 140 may have a hole 147 formed through the upper portion of the corner portions 142-1 to 142-4. For example, the number of holes 147 in the housing 140 may be equal to the number of support members 220.

[0149] In another embodiment, the housing 140 may include a clearance portion configured to avoid spatial interference with the support member 220. Here, the clearance portion may have a structure recessed from the outer surface of a corner portion of the housing 140. At least a portion of the clearance portion may be exposed from the outer surface of the corner portion.

[0150] At least a portion or one end (or upper end) of the support member 220 may be connected or coupled to the upper elastic member 150 through the hole 147 in the housing 140.

[0151] For example, to facilitate the application or reception of a damper, the orifice 147 may have a portion whose diameter gradually increases in the direction from the upper surface of the housing 140 toward the lower surface. In another embodiment, the diameter of the orifice 147 may be constant.

[0152] Not only to limit the path through which the support member 220 extends, but also to avoid spatial interference between the support member 220 and the corner portions 142-1 to 142-4 of the housing 140, clearance grooves 148a may be formed in the outer surfaces 148 of the corner portions 142-1 to 142-4, respectively. Each clearance groove 148a may connect to a hole 147 in the housing 140. The clearance groove 148a may be positioned below the hole 147 in the housing 140. Each clearance groove 148a may have a semi-circular or semi-elliptical segment, but this disclosure is not limited thereto. The lower portion or lower end of the clearance groove 148a may connect to the lower surface of the housing 140. In another embodiment, the clearance groove 148a may be spaced apart from the lower surface of the housing 140. For example, the clearance groove 148a may have a portion whose diameter gradually increases in the direction from the upper portion of the housing 140 toward the lower portion. For example, housing 140 may include a protrusion 149 projecting from the outer surface 148 of corner portion 142 (see [reference]). Figure 17b The hole 147 can be formed through the protrusion 149. For example, the support member 220 can extend through the protrusion 149 of the housing 140.

[0153] To prevent direct collision between the housing 140 and the inner surface of the upper plate 301 of the cover member 300, the housing 140 may include a stop portion 145 protruding from the upper portion, upper end, or upper surface of the housing 140. For example, the stop portion 145 may be provided on the upper surface of at least one of the corner portions 142-1 to 142-4 of the housing 140. In another embodiment, the stop portion 145 may be provided on at least one of the side portions 141-1 to 141-4 of the housing 140.

[0154] To prevent the lower surface of housing 140 from colliding with base 210 and / or circuit board 250, housing 140 may also include a stop (not shown) provided at the lower portion, lower end, or lower surface of housing 140.

[0155] The housing 140 may include a guide protrusion 144 disposed on a corner portion 142. The guide protrusion 144 may be formed at the edge of the upper surface of the corner portion 142 of the housing 140. The guide protrusion 144 may prevent the damper 97 disposed in the hole 147 in the housing 140 (see Figure 6a and Figure 6b Overflow. For example, the hole 147 in the housing 140 may be located between the edge of the upper surface of the corner portion 142 of the housing 140 and the stop portion 145.

[0156] The housing 140 may include a first connector 143 disposed on the upper portion, upper end, or upper surface of the housing and connected to the upper elastic member 150. The first connector 143 may be connected to a first outer frame 152 of the upper elastic member 150. The first connector 143 of the housing 140 may be disposed on at least one of the side portion 141 or the corner portion 142 of the housing 140. The housing 140 may include a second connector 149 disposed on the lower portion, lower end, or lower surface of the housing 140 and connected to the lower elastic member 160. The second connector 149 may be connected to a second outer frame 162 of the lower elastic member 160.

[0157] For example, each of the first connector 143 and the second connector 149 of the housing 140 may have a protruding shape. In another embodiment, at least one of the first connector 143 and the second connector 149 may have a groove or a flat surface shape. For example, the first connector 143 of the housing 140 may be bonded to a hole 152a in the first outer frame 152 of the upper resilient member 150 using an adhesive member (e.g., solder) or by thermal fusion, and the second connector 149 of the housing 140 may be bonded to a hole 162a in the second outer frame 162 of the lower resilient member 160 using an adhesive member (e.g., solder) or by thermal fusion.

[0158] In order to avoid spatial interference with the portion of the second outer frame 162-1 to 162-3 of the lower elastic member 160 that is connected to the second frame connector 163, a clearance groove 44a may be formed in the lower surface of the side portion 141 of the housing 140.

[0159] The first magnet 130 may be disposed on or attached to the housing 140. For example, the first magnet 130 may be disposed on a corner (or corner portion 142) of the housing 140. In another embodiment, the first magnet 130 may be disposed on a side portion 141 of the housing 140.

[0160] For example, the first magnet 130 may include a plurality of magnet units 130-1 to 130-4. Although in Figure 2 The first magnet 130 has four magnet units, but in another embodiment, the first magnet 130 may have two, three, five or more magnet units. For example, multiple magnet units 130-1 to 130-4 may be respectively disposed at the corners of the housing 140.

[0161] At the initial position of the AF moving unit, the first magnet 130 can be disposed on the housing 140 such that at least a portion of the first magnet 130 overlaps with the first coil 120 in a direction parallel to a line perpendicular to the optical axis OA and extending through the optical axis OA. For example, the first magnet 130 can be inserted into or disposed on the sitting portion 141a of the housing 140. In another embodiment, the first magnet 130 can be disposed on the outer or inner surface of the corner portion 142.

[0162] Reference Figure 15 and Figure 16 The first magnet 130 may be in the form of a polyhedron that can be easily seated on a corner portion of the housing 140. For example, the surface area of ​​the first surface 11a of the first magnet 130 may be greater than the surface area of ​​the second surface 11b of the first magnet 130. The first surface 11a of the first magnet 130 may be a surface facing the first coil 120 (or the outer surface of the coil holder 110), and the second surface 11b may be a surface opposite to the first surface 11a. For example, the lateral length of the second surface 11b of the first magnet 130 in the lateral direction may be less than the lateral length of the first surface 11a of the first magnet 130 in the lateral direction.

[0163] For example, the lateral direction of the first surface 11a of the first magnet 130 can be such that it is perpendicular to the direction from the lower surface of the first magnet 130 toward the upper surface, or it can be perpendicular to the optical axis on the first surface 11a of the first magnet 130. Similarly, the lateral direction of the second surface 11b of the first magnet 130 can be such that it is perpendicular to the direction from the lower surface of the first magnet 130 toward the upper surface, or it can be perpendicular to the optical axis on the second surface 11b of the first magnet 130.

[0164] For example, the first magnet 130 may include a portion Q2 in which its lateral length L2 gradually decreases in the direction from the center of the housing 140 toward the corner portions 142-1, 142-2, 142-3, or 142-4 of the housing. For example, the first magnet 130 may include a portion Q2 in which the lateral length L2 of the first magnet 130 decreases in the direction from the first surface 11a of the first magnet 130 toward the second surface 11b. For example, the lateral direction of the first magnet 130 may be parallel to the first surface 11a of the first magnet 130.

[0165] Each of the magnet units 130-1 to 130-4 can be integrally formed and can be oriented such that the first surface 11a facing the first coil 120 is the S pole and the second surface 11b is the N pole. In another embodiment, each of the magnet units 130-1 to 130-4 can be oriented such that the first surface 11a is the N pole and the second surface 11b is the S pole.

[0166] For example, the first magnet 130 may be disposed or mounted on a corner portion of the housing 140 such that at least two magnet units are opposite each other. For example, two pairs of magnet units, each pair opposite each other, are disposed on corner portions 142-1 to 142-4 of the housing. Here, the horizontal surface of each magnet unit in magnet units 130-1 to 130-4 may have a polygonal shape, such as a triangle, pentagon, hexagon, or rhombus.

[0167] In another embodiment, a pair of opposing magnet units may be disposed only on two opposing corner portions of the housing 140. In another embodiment, the first magnet may be disposed on two opposing side portions of the housing 140. In yet another embodiment, the first magnet may be disposed on all four side portions of the housing 140. In yet another embodiment, the first magnet may be disposed on three side portions of the housing 140.

[0168] Despite Figure 1 In the illustrated embodiment, the first magnet 130 is disposed on the housing 140. However, in another embodiment, the first magnet 130 may be disposed on or connected to the coil holder 110, and the first coil 120 may be disposed on or connected to the housing 140. Alternatively, the first coil 120 may be disposed on or connected to the circuit board 190.

[0169] Reference Figure 5 , Figure 6a and Figure 6bEach of the second magnet 180 and the third magnet 185 may not overlap with the first coil 120 in a direction perpendicular to the optical axis OA or in a direction parallel to a line perpendicular to the optical axis OA and extending through the optical axis. In another embodiment, each of the second magnet 180 and the third magnet 185 may overlap with the first coil 120.

[0170] The second magnet 180 may overlap 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 extending through the optical axis. In another embodiment, the second magnet 180 may not overlap with the third magnet 185.

[0171] At the initial position of the AF moving unit, the first position sensor 170 may overlap with the second magnet 180 and 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 extending through the optical axis. In another embodiment, the first position sensor 170 may not overlap with at least one of the second magnet 180 and the third magnet 185.

[0172] Furthermore, 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 extending through the optical axis. For example, the first position sensor 170 may not overlap with the first magnet 130 in a direction opposite to the optical axis or in a direction perpendicular to the outer surface of the first side portion 141-1 of the housing 140.

[0173] The circuit board 190 may be disposed on or attached to the housing 140. For example, the circuit board 190 may be disposed on a side portion (e.g., 141-1) of the housing 140.

[0174] The first position sensor 170 may be disposed on the housing 140. For example, the circuit board 190 may be disposed in the mounting recess 14a in the housing 140. For example, the first position sensor 170 may be disposed on or mounted on the circuit board 190. For example, the first position sensor 170 may be connected to the circuit board 190 via conductive adhesive or solder. The first position sensor 170 may be conductively connected to the circuit board 190 via conductive adhesive or solder.

[0175] The circuit board 190 can be disposed between the first corner portion 142-1 and the second corner portion 142-2 of the housing 140. For example, the circuit board 190 may not overlap with the imaginary line connecting the corner portion (e.g., the first corner portion 142-1) or the corner of the housing 140 to the optical axis OA. This is done to prevent spatial interference between the support member 220 and the circuit board 190.

[0176] Reference Figure 7a and Figure 7b The circuit board 190 may include a plurality of terminals B1 to B6. The terminals B1 to B6 of the circuit board 190 may be electrically connected to the first position sensor 170.

[0177] The first position sensor 170 can be disposed on the first surface 19a of the circuit board 190, and terminals B1 to B6 can be disposed on the second surface 19b of the circuit board 190. Here, the second surface 19b of the circuit board 190 can be the surface opposite to the first surface 19a of the circuit board 190. For example, the first surface 19a of the circuit board 190 can be the surface of the circuit board 190 facing the coil holder 110. The second surface 19b of the circuit board 190 can be the surface facing the side plate 302 of the cover member 300. In another embodiment, terminals can be disposed on the first surface 19a of the circuit board 190.

[0178] The circuit board 190 may include a body portion S1 and an extension portion S2 positioned below the body portion S1. The body portion S1 may be alternatively referred to as the "upper portion", and the extension portion S2 may be alternatively referred to as the "lower portion". The extension portion S2 may extend downward from the body portion S1.

[0179] The body portion S1 may have a form that protrudes relative to 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 19a of the extension portion S2 to the second surface 19b. 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.

[0180] For example, the first extension region A1 may extend or protrude from the first side surface 16a of the extension portion S2, and the second extension region A2 may extend or protrude from the second side surface 16b of the extension portion S2.

[0181] For example, although in Figure 7a The lateral length of the first extension region A1 is shown to be greater than the lateral length of the second extension region A2, but this disclosure is not limited thereto. In another embodiment, the lateral length of the first extension region A1 may be equal to or less than the lateral length of the second extension region A2. 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.

[0182] For example, the first terminals B1 to the fourth terminals B4 of the circuit board 190 can be arranged spaced apart from each other on the first surface 19b. For example, the four terminals B1 to B4 can be arranged in a straight line in the lateral direction of the circuit board 190 or in a direction parallel to the circuit board 190.

[0183] The first terminal B1 and the second terminal B2 can be disposed adjacent to the two ends of the body portion S1 of the circuit board 190. In other words, each of the first terminal B1 and the second terminal B2 can be disposed adjacent to a corresponding end of the two ends of the body portion S1 of the circuit board 190. For example, the first terminal B1 of the circuit board 190 can be disposed on one end of the circuit board 190 (e.g., a side portion of the upper end), and the second terminal B2 can be disposed on the other end of the circuit board 190. The third terminal B3 can be disposed between the first terminal B1 and the second terminal B2, and the fourth terminal B4 can be disposed between the third terminal B3 and the first terminal B1. The first terminal B1 of the circuit board 190 can be disposed in a first extension region A1 of the body portion S1 of the circuit board 190, and the second terminal B2 can be disposed in a second extension region A2 of the body portion S1 of the circuit board 190.

[0184] The first terminals B1 to the fourth terminals B4 can be positioned closer to the upper surface 19c than to the lower surface of the circuit board 190. For example, the first terminals B1 to the fourth terminals B4 can be positioned on the upper side of the second surface 19b of the circuit board 190. For example, the first terminals B1 to the fourth terminals B4 can be formed to contact the upper surface 19c of the body portion S1 of the circuit board 190.

[0185] For example, at least one of the first terminals B1 to the fourth terminals B4 may include a recess or via 7a formed in the upper surface 19c of the circuit board 190. For example, each of 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 semi-circular via or recess 7a. With the help of the recess 7a, the contact area between the solder and the terminals B3 and B4 is increased, thereby improving adhesion and solderability.

[0186] For example, the fifth terminal B5 and the sixth terminal B6 can be positioned spaced apart from the second surface 19b of the extension S2 of the circuit board 190. The fifth terminal B5 and the sixth terminal B6 of the circuit board 190 can be disposed below the first terminals B1 to the fourth terminals B4 of the circuit board 190. For example, the fifth terminal B5 and the sixth terminal B6 can be disposed below the first position sensor 170.

[0187] The circuit board 190 may have a recess 8a or a hole disposed between the fifth terminal B5 and the sixth terminal B6. The recess 8a may be recessed from the lower surface of the circuit board 190 and may be open at both the first surface 19b and the second surface 19a of the circuit board 190.

[0188] The distance between the fifth terminal B5 and the sixth terminal B6 can be less than the distance between two adjacent terminals from the first terminal B1 to the fourth terminal B4. Therefore, since solder is not applied to the portion between the fifth terminal B5 and the sixth terminal B6 by means of the groove 8a, an electrical short circuit between the fifth terminal B5 and the sixth terminal B6 can be prevented.

[0189] For example, at least one of the fifth terminal B5 and the sixth terminal B6 may include a recess 7b or a via formed in the lower surface of the circuit board 190. For example, the fifth terminal B5 and the sixth terminal B6 may include a curved portion recessed from the lower surface of the circuit board 190, such as a semi-circular via or recess. The recess 7b increases the contact area between the solder and the fifth terminal B5 and the sixth terminal B6, thereby improving adhesion and solderability.

[0190] The circuit board 190 may include a recess 90a formed between the second terminal B2 and the third terminal B3, and a recess 90b formed between the first terminal B1 and the fourth terminal B4. Here, recesses 90a and 90b may alternatively be referred to as “avoidance recesses”. Each of the first recess 90a and the second recess 90b may be recessed from the upper surface 19c of the circuit board 190 and may be open at both the first surface 19a and the second surface 19b of the circuit board 190. The first recess 90a in 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 recess 90b in 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.

[0191] For example, circuit board 190 can be implemented as a printed circuit board or an FPCB.

[0192] The circuit board 190 may include circuit patterns or wires (not shown) for electrically connecting the first terminal B1 to the sixth terminal B6 to the first position sensor 170.

[0193] The first position sensor 170 can detect the displacement or position of the coil holder 110 in the optical axis direction. For example, the first position sensor 170 can detect the magnetic field or magnetic field strength of the second sensing magnet 180 mounted on the coil holder 110 during the movement of the coil holder 110, and the first position sensor 170 can output an output signal corresponding to the detection result.

[0194] The first position sensor 170 may be disposed on the housing 140. The first position sensor 170 may be disposed on the circuit board 190. The first position sensor 170 may be disposed on a first surface 19a of the circuit board 190. In another embodiment, the first position sensor 170 may be disposed on a second surface 19b of the circuit board 190. For example, the first position sensor 170 may be disposed in a mounting recess 14b in the housing 190 and may move with the housing 140 during hand tremor correction.

[0195] The first position sensor 170 may be a driver IC (integrated circuit) including a Hall sensor. For example, the first position sensor 170 may include a Hall sensor 61 and a driver 62.

[0196] For example, the Hall sensor 61 can be made of silicon, and the output VH of the Hall sensor 61 can increase with increasing ambient temperature. For example, the ambient temperature can be the temperature of the lens drive device, such as the temperature of the circuit board 190, the temperature of the Hall sensor 61, or the temperature of the driver 62. In another embodiment, the Hall sensor 61 can be made of GaAs, and the output VH of the Hall sensor 61 can decrease with increasing ambient temperature. In another embodiment, the output of the Hall sensor 61 can have a slope of approximately -0.06% relative to the ambient temperature.

[0197] The first position sensor 170 may further include a temperature sensing element 63 capable of detecting ambient temperature. The temperature sensing element 63 may output a temperature detection signal Ts corresponding to the ambient temperature detection result of the first position sensor 170 to the driver 62.

[0198] For example, the Hall sensor 61 of the first position sensor 190 can generate an output VH corresponding to the detection result of the magnetic force intensity of the second magnet 180. For example, the intensity of the output of the first position sensor 190 can be proportional to the detected magnetic force intensity of the second magnet 180.

[0199] The driver 62 can output a drive signal dV for driving the Hall sensor 61 and a drive signal Id1 for driving the first coil 120. For example, the driver 62 can receive a clock signal SCL, a data signal SDA, and power signals VDD and GND via data communication using a protocol such as I2C communication. Here, although the first power signal GND can be ground voltage or 0 V and the second power signal VDD can be a predetermined voltage for driving the driver 62, and the first power signal GND and the second power signal VDD can be DC voltage and / or AC voltage, this disclosure is not limited thereto.

[0200] The driver 62 can use the clock signal SCL and the power signals VDD and GND to generate a drive signal dV for driving the Hall sensor 61 and a drive signal Id1 for driving the first coil 120.

[0201] Furthermore, the driver 62 can receive the output VH of the Hall sensor 61, and can use protocols such as I2C communication to send the clock signal SCL and data signal SDA related to the output VH of the Hall sensor 61 to the controllers 830 and 780 via data communication. Additionally, the driver 62 can receive the temperature detection signal Ts, which is the detection result of the temperature sensing element 63, and can use protocols such as I2C communication to send the temperature detection signal Ts to the controllers 830 and 780 via data communication.

[0202] Controllers 830 and 780 can perform temperature compensation on the output VH from Hall sensor 61 based on changes in ambient temperature detected by the temperature sensing element 63 of the first position sensor 170. For example, when the drive signal dV or bias signal of Hall sensor 61 is 1 mA, the output VH of Hall sensor 61 of the first position sensor 170 can be -20 mV to +20 mV. In the case of temperature compensation for the output VH of Hall sensor 61 having a negative gradient with respect to changes in ambient temperature, the output VH of Hall sensor 61 of the first position sensor 170 can be 0 mV to +30 mV.

[0203] When the output of the Hall sensor 61 of the first position sensor 170 is plotted on the xy coordinate system, the output range of the Hall sensor 61 of the first position sensor 170 is represented in the first quadrant (e.g., 0 mV ~ +30 mV) for the following reason.

[0204] Because the outputs of Hall sensor 61 in the first quadrant of the xy coordinate system and Hall sensor 61 in the third quadrant of the xy coordinate system shift in opposite directions according to changes in ambient temperature, the accuracy and reliability of the Hall sensors may decrease when both the first and third quadrants are used as the AF operation control area. Therefore, in order to accurately compensate for changes in ambient temperature, a specific range in the first quadrant can be considered as the output range of Hall sensor 61 of the first position sensor 170.

[0205] The first position sensor 170 may include a first terminal and a second terminal for two power signals VDD and GND, a third terminal for a clock signal SCL, a fourth terminal for data SDA, and a fifth terminal and a sixth terminal for providing a drive signal to the first coil 120.

[0206] Each of the first to fourth terminals of the first position sensor 170 can be electrically connected to a corresponding one of the first to fourth terminals B1 to B4 of the circuit board 190. Each of the fifth and sixth terminals of the first position sensor 170 can be electrically connected to a corresponding one of the fifth terminal B5 and the sixth terminal B6 of the circuit board 190.

[0207] In the first terminal B1 to the fourth terminal B4 of the circuit board 190, two terminals can be configured for two power signals VDD and GND, another terminal can be configured for a clock signal SCL, and the remaining terminal can be configured for data SDA.

[0208] For example, the first terminal B1 and the second terminal B2 of the circuit board 190 can be configured for two power signals VDD and GND of the first position sensor 170, and one of the third terminal B3 and the fourth terminal B4 can be configured for a clock signal SCL. The other of the third terminal B3 and the fourth terminal B4 can be configured for data SDA, and the fifth terminal B5 and the sixth terminal B6 can be configured to provide a drive signal to the first coil 120.

[0209] In another embodiment, the first position sensor 170 may be implemented as a single position detection sensor, such as a Hall sensor.

[0210] The first terminals B1 to the fourth terminals B4 of the circuit board 190 can be conductively connected to the upper elastic units 150-1 to 150-4 and the support members 220A to 220D. The first terminals B1 to the fourth terminals B4 of the circuit board 190 can also be conductively connected to terminals 251-1 to 251-n (where n is a natural number greater than 1) of the circuit board 250 via the upper elastic units 150-1 to 150-4 and the support members 220A to 220D. Therefore, the first position sensor 170 can be conductively connected to terminals 251-1 to 251-n (n=4) of the circuit board 250.

[0211] The first position sensor 170 can be electrically connected to the first coil 120. The first position sensor 170 can supply a drive signal or power to the first coil 120. For example, the first coil 120 can be electrically connected to the fifth terminal B5 to the sixth terminal B6 of the circuit board 190. For example, the first position sensor 170 can supply a drive signal or power to the first coil 120 through the fifth terminal B5 and the sixth terminal B6.

[0212] For example, the fifth terminal B5 and the sixth terminal B6 of the circuit board 190 can be connected to or coupled to the lower elastic units 160-1 and 160-2. For example, the fifth terminal B5 and the sixth terminal B6 of the circuit board 190 can be conductively connected to the lower elastic units 160-1 and 160-2 via solder or conductive adhesive. For example, the first coil 120 can be conductively connected to the lower elastic units 160-1 and 160-2. The fifth terminal and the sixth terminal of the first position sensor 170 can be conductively connected to the first coil 120 via the lower elastic units 160-1 and 160-2.

[0213] For example, one end of the first coil 120 may be electrically connected to the first lower elastic unit 160-1, and the other end of the first coil 120 may be electrically connected to the first lower elastic unit 160-1. For example, the fifth terminal B5 of the circuit board 190 may be connected or electrically connected to the first lower elastic unit 160-1. The sixth terminal B6 of the circuit board 190 may be connected or electrically connected to the second lower elastic unit 160-2.

[0214] Reference Figures 8 to 14 The upper elastic member 150 can be connected to the upper part, upper end, or upper surface of the coil frame 110. The lower elastic member 160 can be connected to the lower part, lower end, or lower surface of the coil frame 110.

[0215] The upper elastic member 150 can be connected to the upper portion, upper end, or upper surface of the coil frame 110 and the upper portion, upper end, or upper surface of the housing 140, and the lower elastic member 160 can be connected to the lower portion, lower end, or lower surface of the coil frame 110 and the lower portion, lower end, or lower surface of the housing 140. At least one of the upper elastic member 150 and the lower elastic member 160 can elastically support the coil frame 140 relative to the housing 140.

[0216] The support member 220 can support the housing 140 to allow the housing 140 to move in a direction perpendicular to the optical axis. The support member 220 can be coupled to the upper elastic member 150. The support member 220 can be electrically connected to the upper elastic member 150. The support member 220 can electrically connect at least one of the upper elastic member 150 or the lower elastic member 160 to the circuit board 250. The support member 220 can electrically connect the upper elastic member 150 to the elastic member 60.

[0217] Reference Figure 8 The upper elastic member 150 may include a plurality of upper elastic units 150-1 to 150-4 electrically isolated from each other. The number of upper elastic units in the upper elastic member 150 may be four. However, in another embodiment, the number of upper elastic units may be one, two, three, five, or more.

[0218] Each of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 can be directly coupled to and thus electrically connected to one of the corresponding first terminals B1 to the fourth terminals B4.

[0219] A portion of each of the plurality of upper elastic units 150-1 to 150-4 may be disposed on the first side portion 141-1 of the housing 140 on which the circuit board 190 is disposed. At least one upper elastic unit may be disposed on each of the remaining second side portions 141-2 to fourth side portions 141-4 of the housing 140 other than the first side portion 141-1.

[0220] At least one of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 may include a first outer frame 152 connected to the housing 140. At least one of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 may also include a first inner frame 151 connected to the coil holder 110 and a first frame connector 153 connecting the first inner frame 151 to the first outer frame 152.

[0221] exist Figure 8 In the illustrated embodiment, each of the first upper elastic unit 150-1 and the second upper elastic unit 150-2 may include only the first outer frame, excluding the first inner frame and the first frame connector, and each of the first upper elastic unit 150-1 and the second upper elastic unit 150-2 may be spaced apart from the coil frame 110. In another embodiment, at least one of the first upper elastic unit 150-1 and the second upper elastic unit 150-2 may include the first inner frame, the first outer frame, and the first frame connecting portion.

[0222] Each of the third upper elastic unit 150-3 and the fourth upper elastic unit 150-4 may include a first inner frame 151, a first outer frame 152 and a first frame connector 153.

[0223] In another embodiment, at least one of the first upper spring unit 150-1 to the fourth upper spring unit 150-4 may include the first outer frame 152, but may not include the first inner frame 151 and the first frame connector 153.

[0224] For example, each of the first inner frames 151 of the third upper elastic unit 150-3 and the fourth upper elastic unit 150-4 may be provided with a hole 151a for connection with the first connector 113 of the coil frame 110. For example, the hole 151a in the first inner frame 151 may have at least one slit 51a located between the first connector 113 and the hole 151a, through which the adhesive member enters.

[0225] Each of the first outer frames 152 of the first upper elastic member 150-1 to the fourth upper elastic member 150-4 may have a hole 152a therein for connection with the first connector 143 of the housing 140.

[0226] The first outer frame 151 of each of the first upper elastic units 150-1 to the fourth upper elastic units 150-4 may include a body portion connected to the housing 140 and connecting terminals P1 to P4 connected to a corresponding one of the first terminals B1 to the fourth terminals B4 of the circuit board 190. Here, the connecting terminals P1 to P4 may alternatively be referred to as "extension portions".

[0227] The upper elastic member 150 may include a first connector 520 connected to the housing 140, a second connector 510 connected to the support member 220, and a connector 530 connecting the first connector 520 to the second connector 510. For example, the first outer frame 151 may include the first connector 520, the second connector 510, and the connector 530.

[0228] For example, the second connector 510 can be connected via solder 901A (see...) Figure 10 It can be attached to a portion (e.g., the lower end) of the support member 220 using a conductive adhesive or other conductive adhesive.

[0229] In addition, the first outer frame 151 may include extensions P1 to P4 that are connected to the first connector 520 and extend to the first side portion 141-1 of the housing 140.

[0230] The body portion of each of the first upper elastic units 150-1 to the fourth upper elastic units 150-4 may include a first connector 520. The body portion of each of the first upper elastic units 150-1 to the fourth upper elastic units 150-4 may also include at least one of a second connector 510 and a connector 530.

[0231] For example, one end of the first support member 220A can be connected to the second connector 510 of the first upper elastic unit 150-1 using solder 901A or conductive adhesive. One end of the second support member 220B can be connected to the second connector 510 of the second upper elastic unit 150-1 using solder 901A or conductive adhesive. One end of the third support member 220C can be connected to the second connector 510 of the third upper elastic unit 150-3 using solder 901A or conductive adhesive. One end of the fourth support member 220D can be connected to the second connector 510 of the fourth upper elastic unit 150-4 using solder 901A or conductive adhesive.

[0232] The second connector 510 may include a clearance portion 52 corresponding to, facing, or overlapping with the support member 220 in the optical axis direction. The clearance portion 52 may have the form of a groove formed by recessing a portion of the second connector 510. One end of a corresponding support member in the support member 220 may be connected via conductive adhesive or solder 910A (see [link to documentation]). Figure 10 The support member 220 is directly connected to the second connector 510, and the second connector 510 and the support member 220 can be electrically connected to each other. In another embodiment, the clearance portion 52 can be a through hole formed through the second connector 510 along the optical axis. One end of the support member 220 can be positioned in the through hole in the second connector 510, or can extend through the through hole in the second connector 510.

[0233] For example, the second connector 510 may include a connection area that is attached to the support member 220 via solder 901A or conductive adhesive. For example, the connection area of ​​the second connector 510 may include the clearance portion 52 and the area surrounding the clearance portion 52.

[0234] The first connector 520 may include at least one connection region (e.g., 5a, 5b) that is connected to the housing (e.g., corner portion 142). For example, the connection region (e.g., 5a, 5b) of the first connector 520 may have at least one hole 152a that is connected to the first connector 143 of the housing 140.

[0235] For example, each of the connection regions 5a and 5b may have at least one hole therein, and each corner portion of the corner portion 142 of the housing 140 may be correspondingly provided with at least one first connector 143.

[0236] For example, in order to support the housing 140 in a balanced state so that it does not tilt to either side, the connection regions 5a and 5b of the first connectors 520 of the first upper elastic units 150-1 to the fourth upper elastic units 150-4 can be symmetrically arranged based on reference lines (e.g., 501 and 502). In another embodiment, the connection regions of the first connectors 520 can be asymmetrical with each other based on reference lines (e.g., 501 and 502).

[0237] Furthermore, the first connector 143 of the housing 140 may be symmetrically arranged based on reference lines (e.g., 501 and 502). In another embodiment, the first connector 143 may be asymmetrical based on reference lines 501 and 502.

[0238] Each of reference lines 501 and 502 may be a line extending between the center point 101 of housing 140 and one of the corners of corner portions 142-1 to 142-4 of housing 140. For example, each of reference lines 501 and 502 may be a line extending through the center point 101 and two corners of corner portions 142-1 to 142-4 of housing 140 that are opposite each other in the diagonal direction of housing 140.

[0239] Here, center point 102 can be the center of opening 102 in coil holder 110, the center of opening 201 in housing 140, or the center of upper elastic member 150. For example, the corner of each corner portion in the corner portion of housing 140 can be aligned with or correspond to the center of a corresponding corner portion in the corner portion of housing 140.

[0240] exist Figure 8 In the illustrated embodiment, each of the connection regions 5a and 5b of the first connector 520 may have an aperture 152a. In another embodiment, each connection region of the first connector 520 may be implemented with various shapes suitable for connection to the housing 140, such as a recessed shape. For example, the aperture 152a in the first connector 520 may have at least one slit 52a that allows adhesive to flow between the first connector 143 of the housing 140 and the aperture 152a.

[0241] The connector 530 of the upper elastic member 150 can connect the second connector 510 to the first connector 520. For example, the connector 530 can connect the second connector 510 to the connection areas 5a and 5b of the first connector 520.

[0242] For example, connector 530 may include a first connector 530a and a second connector 530b, the first connector 530a connecting a first connection region 5a of a first connector 520 of each of the first upper elastic units 150-1 to the fourth upper elastic units 150-4 to a second connector 510, and the second connector 530b connecting a second connection region 5b of the first connector 520 to the second connector 510. Although in Figure 8 In one embodiment, the number of connectors 530 provided on a corner portion of the housing 140 is two, but in another embodiment, the number of connectors 530 provided on a corner portion of the housing 140 can be one.

[0243] For example, the first outer frame 151 of at least one of the first upper elastic units 150-1 to the fourth upper elastic units 150-4 may include a connection region 156 configured to directly connect the first connection region 5a to the second connection region 5b. In another embodiment, the first outer frame 151 may not include the connection region 156.

[0244] Each of connectors 530, 530a, and 530b may include a bent portion or a bent portion that has been bent at least once. In another embodiment, the connector may be linear.

[0245] The width of connector 530 may be smaller than the width of first connector 520. Furthermore, the width of connector 530 may be smaller than the width (or diameter) of the first connector. In another embodiment, the width of connector 530 may be equal to the width of the first connector 520, or may be equal to the width (or diameter) of the first connector.

[0246] For example, the first connector 520 may contact the upper surface of the corner portions 142-1 to 142-4 of the housing 140, and the first connector 520 may be supported thereon. For example, the connector 530 may not be supported by the upper surface of the housing 140, and the connector 530 may be spaced apart from the housing 140. Furthermore, to prevent oscillations caused by vibration, the space between the connector 530 and the housing 140 may be filled with a damper (not shown), and the damper may contact at least a portion of the connector 530 and the housing 140.

[0247] The width of each of connectors 530, 530a, and 530b may be smaller than the width of the first connector 520, thereby allowing connector 530 to move easily in the first direction. Therefore, the stress applied to the upper elastic elements 150-1 to 150-4 and the stress applied to the support members 220A to 220D can be dispersed.

[0248] Each of the first extension portion P1 and the second extension portion P2 of the first outer frame of the first upper elastic unit 150-1 and the second upper elastic unit 150-2 can extend from the first connector 520 (e.g., the first connection area 5a) toward the corresponding one of the first terminal B1 and the second terminal B2 of the circuit board 190 located at the first side portion 141-1 of the housing 140.

[0249] The first connector 520 of the third upper elastic unit 150-3 may further include at least one connection region 6a, 6b connected to at least one of the fourth side portion 141-4 and the second corner portion 142-2 of the housing 140.

[0250] The first connector 520 of the fourth upper elastic unit 150-4 may also include at least one connection region 6c, 6d connected to at least one of the second side portion 141-2 and the first corner portion 142-1 of the housing 140.

[0251] Each of the third extension portion P3 and the fourth extension portion P4 of the first outer frame of the third upper elastic unit 150-3 and the fourth upper elastic unit 150-4 can extend from the first connector 520 (e.g., connection areas 6b, 6d) toward the corresponding one of the third terminal B3 and the fourth terminal B4 of the circuit board 190 located at the first side portion 141-1 of the housing 140.

[0252] One end of each of the first extension portion P1 to the fourth extension portion P4 may be connected to a corresponding one of the first terminals B1 to the fourth terminals B4 of the circuit board 190 via solder or conductive adhesive. For example, each of the first extension portion P1 and the second extension portion P2 may have a linear shape. For example, to facilitate connection to a corresponding one of the third terminal B3 and the fourth terminal B4 of the circuit board 190, each of the third extension portion P3 and the fourth extension portion P4 may include a bent portion or a curved portion.

[0253] The first outer frame of the third upper elastic unit 150-3 may also include a first extension frame 154-1, which is connected to both the first connector 520 and the extension portion P3, and is positioned at the fourth side portion 141-4 and the second corner portion 142-2 of the housing 140.

[0254] To increase the connection force between the first extension frame 154-1 and the housing 140 so as to prevent the third upper elastic unit 150-3 from being lifted, the first extension frame 154-1 may include at least one connection region 6a, 6b connected to the housing 140, and each of the connection regions 6a and 6b may have a hole for connection to the first connector 143 of the housing 140.

[0255] The first outer frame of the fourth upper elastic unit 150-4 may also include a second extension frame 154-2, which is connected to both the first connector 520 and the extension portion P4, and is positioned at the second side portion 141-2 and the first corner portion 142-1 of the housing 140.

[0256] To improve the connection force between the second extension frame 154-2 and the housing 140 and thus prevent the fourth upper elastic unit 150-4 from being lifted, the second extension frame 154-2 may include at least one connection region 6c, 6d connected to the housing 140, and each of the connection regions 6c, 6d may have a hole for connection to the first connector 143 of the housing 140.

[0257] Despite Figure 8 In the present disclosure, each of the third upper elastic unit 150-3 and the fourth upper elastic unit 150-4 includes two first frame connectors, but the present disclosure is not limited thereto, and the number of first frame connectors may be one, three or more.

[0258] As described above, each of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 may include extensions P1 to P4 disposed on the first side portion 141-1 of the housing 140. With the aid of the extensions P1 to P4, each of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 can be easily connected to the first terminal B1 to the fourth terminal B4 disposed on the body portion S1 of the circuit board 190.

[0259] Since the four terminals B1 to B4 located at the body portion S1 of the circuit board 190—which is located on the first side portion 141-1 of the housing 140—are electrically and directly connected to the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4, a portion of the first outer frame 151 of each of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 can be located on the first side portion 141-1 of the housing 140.

[0260] Each of the upper elastic units 150-1 to 150-4 may be disposed on a corresponding corner portion 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.

[0261] Each of the extensions P1 to P4 of each of the upper elastic units 150-1 to 150-4 can be directly connected to one of the four terminals B1 to B4 provided on the body portion S1 of the circuit board 190 via a conductive adhesive 71 such as solder.

[0262] The first outer frame 151 of the first upper elastic unit 150-1 can be disposed on the first corner portion 142-1 of the housing 140, and the first outer frame 151 of the second upper elastic unit 150-2 can be disposed on the second corner portion 142-2 of the housing 140, the first outer frame 151 of the third upper elastic unit 150-3 can be disposed on the third corner portion 142-3 of the housing 140, and the first outer frame 151 of the fourth upper elastic unit 150-4 can be disposed on the fourth corner portion 142-4 of the housing 140.

[0263] A portion of the third upper elastic unit 150-3 may be disposed in the first groove 90a in the first circuit board 190, and the end of this portion of the third upper elastic unit 150-3 may be connected to the third terminal B3 of the circuit board 190.

[0264] A portion of the fourth upper elastic unit 150-4 may be disposed in the second groove 90b in the first circuit board 190, and the end of this portion of the fourth upper elastic unit 150-4 may be connected to the fourth terminal B4 of the circuit board 190.

[0265] The third extension portion P3 of the third upper elastic unit 150-3 can extend through the first groove 90a in the circuit board 190 toward the third terminal B3 of the circuit board 190, and the third extension portion P3 of the third upper elastic unit 150-3 can be bent at least twice.

[0266] The fourth extension P4 of the fourth upper elastic unit 150-4 can extend through the second groove 90b in the circuit board 190 toward the fourth terminal B4 of the circuit board 190, and the fourth extension P4 of the fourth upper elastic unit 150-4 can be bent at least twice.

[0267] The third extension portion (or "third connection terminal") P3 of the third upper elastic unit 150-3 may include at least two bending regions 2a and 2b. 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 connector 520 (e.g., connection region 6b) of the third upper elastic unit 150-3, a first bending region (or "first bending portion") 2a bent at the edge of the first portion 1a, a second portion 1b extending from the first bending region 2a, a second bending region (or "second bending portion") 2b bent at the edge of the second portion 1b, and a third portion 1c extending from the second bending region 2b toward the third terminal B3.

[0268] For example, the second portion 1b of the third extension (or the third connecting terminal) P3 can be bent at the edge of the first portion 1a, and the third portion 1c can be bent at the edge of the second portion 1b. The second portion 1b of the third extension P3 can be disposed between the first bending region 2a and the second bending region 2b, and the second portion 1b of the third extension P3 can connect the first bending region 2a and the second bending region 2b to each other. For example, each of the first portion 1a and the third portion 1c of the third extension P3 can extend from the second corner portion 142-2 of the housing 140 toward the first corner portion 141-1. For example, the second portion 1b of the third extension P3 can extend from the inner surface of the housing 140 toward the outer surface. A portion of the third extension P3 of the third upper elastic unit 150-3 (e.g., the second portion 1b) can be positioned in the first groove 90a in the circuit board 190 or can extend through the first groove 90a.

[0269] The fourth extension portion (or "fourth connecting terminal") P4 of the fourth upper elastic unit 150-4 may include at least two bending regions 2c and 2d. 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 connector 520 (e.g., connecting region 6d) of the fourth upper elastic unit 150-4, a third bending region (or "third bending portion") 2c bent at the edge of the fourth portion 1d, a fifth portion 1e extending from the third bending region 2c, a fourth bending region (or "fourth bending portion") 2d bent at the edge of the fifth portion 1e, and a sixth portion 1f extending from the fourth bending region 2d toward the fourth terminal B4. For example, the fifth portion 1e of the fourth extension portion (or fourth connecting terminal) P4 may be bent at the edge of the fourth portion 1d, and the sixth portion 1f may be bent at the edge of the fifth portion 1e. The fifth part 1e of the fourth extension P4 can be set between the third bending region 2c and the fourth bending region 2d so as to connect the third bending region 2c and the fourth bending region 2d to each other.

[0270] For example, each of the fourth portion 1d and the sixth portion 1f of the fourth extension P4 may extend from the first corner portion 142-1 of the housing 140 toward the second corner portion 141-2. For example, the fifth portion 1e of the fourth extension P4 may extend from the inner surface of the housing 140 toward the outer surface. A portion of the fourth extension P4 of the fourth upper elastic unit 150-4 (e.g., the fifth portion 1e) may be positioned in the second recess 90b in the circuit board 190 or may extend through the second recess 90b.

[0271] Reference Figure 9The lower elastic member 160 can be connected to both the coil frame 110 and the housing 140. The lower elastic member 160 can be connected to both the lower portion, lower surface or lower end of the coil frame 110 and the lower portion, lower surface or lower end of the housing 140.

[0272] The lower elastic member 160 may include a plurality of lower elastic units 160-1 and 160-2. For example, each of the first lower elastic unit 160-1 and the second lower elastic unit 160-2 may include: a second inner frame 161, which is coupled or fixed to the lower portion, lower surface or lower end of the coil frame 110; a second outer frame 162-1 to 162-3, which is coupled or fixed to the lower portion, lower surface or lower end of the housing 140; and a second frame connector 163, which connects the second inner frame 161 to the second outer frames 162-1 to 162-3.

[0273] The second inner frame 161 may have a hole 161a for connecting with the second connector 117 of the coil holder 110, and the second outer frames 162-1 to 162-3 may have holes 162a for connecting with the second connector 149 of the housing 140.

[0274] For example, although each of the first lower elastic unit 160-1 and the second lower elastic unit 160-2 may include three second outer frames 162-1 to 162-3 coupled to the housing 140 and two second frame connectors 163, this disclosure is not limited thereto. In another embodiment, each of the first lower elastic unit and the second lower elastic unit may include at least one second outer frame and at least one second frame connector.

[0275] Each of the first lower elastic unit 160-1 and the second lower elastic unit 160-2 may include connecting frames 164-1 and 164-2 that connect the second outer frames 162-1 and 162-3 to each other. Although the width of each connecting frame in connecting frames 164-1 and 164-2 may be smaller than the width of the second outer frames 162-1 to 162-3, this disclosure is not limited thereto. Based on the coil units 230-1 to 230-4 and the magnet units 130-1 to 130-4, connecting frames 164-1 and 164-2 may be positioned outside the coil units 230-1 to 230-4 and the magnet units 130-1 to 130-4 to avoid spatial interference with the second coil 230 and the first magnet 130. Here, the outer side of coil units 230-1 to 230-4 and magnet units 130-1 to 130-4 can be the side opposite to the center of coil frame 110 or housing 140 based on coil units 230-1 to 230-4 and magnet units 130-1 to 130-4.

[0276] For example, although connecting frames 164-1 and 164-2 may be positioned so as not to overlap with coil units 230-1 to 230-4 and / or magnet units 130-1 to 130-4 in the optical axis direction, this disclosure is not limited thereto. In another embodiment, at least a portion of connecting frames 164-1 and 164-2 may be aligned with or overlap with coil units 230-1 to 230-4 and / or magnet units 130-1 to 130-4 in the optical axis direction.

[0277] Each of the upper elastic units 150-1 to 150-4 and the lower elastic units 160-1 and 160-2 can be implemented as a leaf spring. In another embodiment, the upper and lower elastic units can be implemented as coil springs or the like. The "elastic unit (e.g., 150 or 160)" mentioned above can be alternatively referred to as a "spring," and the "outer frame (e.g., 152 or 162)" can be alternatively referred to as an "outer part." Furthermore, the "inner frame (e.g., 151 or 161)" can be alternatively referred to as an "inner part," and the "support member (e.g., 220)" can be alternatively referred to as a "linear member."

[0278] The elastic member 60 may be disposed on or attached to the fixing unit. The elastic member 60 may be disposed on the base 210. The elastic member 60 may be attached to the base 210. The elastic member 60 may be fixed to the base 210. For example, the elastic member 60 may be attached or fixed to the base 210 via an adhesive. In another embodiment, the elastic member 60 may be integrally formed with the base 210. In another embodiment, the elastic member 60 may be integrally formed with the base 210 by insert injection molding. In another embodiment, at least a portion of the elastic member 60 may be disposed in the base, and at least another portion of the elastic member 60 may be exposed or open from the base 210.

[0279] The elastic member can be alternatively referred to as a "shock absorber," "elastic part," "connecting elastic part," "elastic unit," "connecting elastic unit," or "spring part." The elastic member 60 can be provided on the corner portion of the base 210.

[0280] The elastic member 60 can be an elastic body. For example, the elastic member 60 can be a spring, a leaf spring, or a suspension spring.

[0281] At least a portion of the elastic member 60 may be coupled to the base 210, and at least another portion of the elastic member 60 may be coupled to the support member 220. The elastic member 60 may be electrically connected to the circuit board 250. The elastic member 60 may be connected via solder 80 (see...) Figure 17d (or conductive adhesive) is conductively connected to the circuit board 250.

[0282] The elastic member 60 can be positioned above the lower surface of the base 210. The elastic member 60 can also be positioned below the circuit board 250.

[0283] Reference Figure 17b The resilient member 60 may include a first connector 61 coupled to the base 210. The resilient member 60 may include a second connector 62 coupled to the support member 220. The resilient member 60 may include a connector 63 connecting the first connector 61 to the second connector 62. The first connector 61 may be alternatively referred to as the "first part," the second connector 62 may be alternatively referred to as the "second part," and the connector 63 may be alternatively referred to as the "third part." The first connector 61 may be electrically connected to the circuit board 250. The first connector 61 may be connected via solder 80 (see...). Figure 17d The connection is electrically attached to the circuit board 250 via solder 80 or conductive adhesive. For example, at least one of the connection areas 61A and 61B can be connected via solder 80 (see [link to solder 80]). Figure 17d (or conductive adhesive) is conductively connected to the circuit board 250.

[0284] The second connector 62 may have a hole 62A through which the support member 220 extends. The hole 62A may be a through hole formed through the second connector 62. The diameter of the hole 62A may be equal to or greater than the diameter of the support member 220. The second connector 62 may include a region of the elastic member 60 adjacent to the hole 62A for solder or conductive adhesive to be disposed therein.

[0285] The first connector 61 may include at least one connection region 61A and 61B connected to the base 210. For example, the first connector 61 may include multiple connection regions. For example, the first connector 61 may include a first connection region 61A connected to one region of a corner portion of the base 210 and a second connection region 61B connected to another region of the corner portion of the base 210. For example, the first connection region 61A may be located on one side of the second connector 62 (or support member 220), and the second connection region 61B may be located on the opposite side of the second connector 62 (or support member 220). For example, the second connector 62 (or support member 220) may be located between the first connection region 61A and the second connection region 61B.

[0286] In another embodiment, the first connector 61 may include a single connection area.

[0287] To support the housing 140 while maintaining balance and preventing eccentricity, the connection regions 61A and 61B of the first connector 61 may have a shape symmetrical with respect to the second connector 62 (or support member 220). Alternatively, the connection regions 61A and 61B of the first connector 61 may be symmetrical with respect to the second connector 62 (or support member 220). In another embodiment, the connection regions 61A and 61B of the first connector 610 may be asymmetrical with respect to the second connector 62 (or support member 220).

[0288] In another embodiment, at least one of the connection regions of the first connector 61 may have a hole through which the first connector 61 is connected to the base 210.

[0289] Connector 63 can be bent or folded at least once. Connector 63 may include at least one bent portion. For example, connector 63 may have a serrated shape, at least one bending area, or at least one folded area.

[0290] Connector 63 can connect the connection area of ​​the first connector 61 to the second connector 62. For example, connector 63 may include a first connector 63A connected to the first connection area 61A of the first connector 61, a second connector 63B connecting the first connector 63A to the second connector 62, and a third connector 63C connecting the second connection area 61B to the portion where the first connector 63A and the second connector 63B are connected.

[0291] In another embodiment, the third connector 63C (or the first connector 63A) may be omitted, and connector 63 may include the first connector 63A (or the third connector 63C) and the second connector 63B. In yet another embodiment, the second connector 63B may be omitted, and the first connection area 61A and the second connection area 61B may be directly connected to the second connector 62.

[0292] The optical axis OA can be positioned closer to the second connector 62 than to the connector 63. For example, the shortest distance between the optical axis OA and the second connector 62 can be less than the shortest distance between the optical axis OA and the connector 63. For example, the shortest distance between the optical axis OA and the support member 220 can be less than the shortest distance between the optical axis OA and the connector 63.

[0293] In another embodiment, the shortest distance between the optical axis OA and the second connector 62 can be equal to or greater than the shortest distance between the optical axis OA and the connector 53. For example, the shortest distance between the optical axis OA and the support member 220 can be equal to or greater than the shortest distance between the optical axis OA and the connector 63.

[0294] Reference Figure 17b The width K4 of connector 63 can be less than the length of the first connector 61 in the direction perpendicular to the optical axis. For example, the width K4 of connector 63 can be less than the minimum length of the first connector 61 in the direction perpendicular to the optical axis. The width K4 of connector 63 can be less than the lateral length K1 of the first connector 61. The width K4 of connector 63 can be less than the longitudinal length K2 of the first connector 61. The width K4 of connector 63 can be less than the diameter K3 of the second connector 62.

[0295] The diameter K3 can be the maximum length of the second connector 62 in the direction perpendicular to the optical axis. The width K4 can be the shortest distance between the two outer surfaces of the connector 63 that are positioned opposite each other in the direction perpendicular to the optical axis. Alternatively, the width K4 can be the length of the connector 63 in the direction perpendicular to the direction in which the connector 63 extends. Alternatively, the width K4 can be the length of the connector 63 in the width direction.

[0296] Length K1 can be the length of the first connector 61 in the longitudinal direction. Alternatively, K1 can be the maximum length of the first connector 61 in the direction perpendicular to the optical axis. Length K2 can be the length of the first connector 61 in the width direction. Alternatively, K2 can be the minimum length of the first connector 61 in the direction perpendicular to the optical axis.

[0297] Since K4 < K1, K4 < K2, or K4 < K3 are true, the elastic modulus of the elastic member 60 can be reduced. Therefore, the elastic member 60 can disperse the stress applied to the support member 220 from the lens with a large diameter, thereby preventing stress-induced breakage of the support member 220.

[0298] The thickness t1 of the first connector 61, the thickness of the second connector 62, and the thickness of the connector 63 can be the same. The thickness t1 can be the length of each of the first connector 61, the second connector 62, and the connector 63 in the optical axis direction. For example, the thickness t1 can be less than the width K4.

[0299] The elastic member 60 may include a plurality of elastic elements 60A to 60D spaced apart from each other. The plurality of elastic elements 60A to 60D may be respectively disposed on the corner portions of the base 210. Each of the plurality of elastic elements 60A to 60D may be disposed on or connected to a corresponding corner portion of the corner portion of the base 210. The descriptions of the first connector 61, the second connector 62, and the third connector 63 may be applied to each of the elastic elements 60A to 60D with or without modification.

[0300] Support member 220 can support the OIS moving unit (e.g., housing 140) relative to the fixed unit (e.g., base 210) such that the OIS moving unit (e.g., housing 140) can move in a direction perpendicular to the optical axis. Support member 220 can be coupled to upper elastic member 150 and elastic member 60. One end (or upper end) of support member 220 can be coupled to upper elastic member 150 (e.g., second connector 510). One end (or upper end) of support member 220 can be coupled to upper elastic member 150 (e.g., second connector 510) via solder 901A or conductive adhesive. The other end (or lower end) of support member 220 can be coupled to elastic member 60 (e.g., second connector 62). The other end (or lower end) of support member 220 can be coupled to elastic member 60 (e.g., second connector 62) via solder 902A or conductive adhesive.

[0301] The support member 220 can electrically connect the upper elastic member 150 to the elastic member 60. The support member 220 can electrically connect the upper elastic member 150, the elastic member 60, and the circuit board 250 to each other.

[0302] The support member 220 may include a plurality of support members 220A to 220D spaced apart from each other. The support member 220 may be disposed on a corner portion 142 of the housing 140. Each of the support members 220A to 220D may be disposed on a corresponding corner portion among the corner portions 142-1 to 142-4 of the housing 140. The support members 220A to 220D may electrically connect the upper elastic units 150-1 to 150-4 to the elastic units 60A to 60D, respectively.

[0303] One end of each of the support members 220A to 220D can be connected to a corresponding one of the first upper elastic units 150-1 to the fourth upper elastic units 150-4, and the other end of each of the support members 220A to 220D can be connected to a corresponding elastic unit of the elastic units 60A to 60D.

[0304] Each of the support members 220A to 220D can be electrically connected to a corresponding terminal of the circuit board 250 from terminals 251-1 to 251-n (n is a natural number greater than 1) via a corresponding elastic unit of elastic units 60A to 60D.

[0305] Support members 220A to 220D may be spaced apart from housing 140 and may not be directly connected or fixed to housing 140. One end of each support member 220A to 220D may be directly connected or connected to the second connector 510 of upper elastic member 150.

[0306] For example, at least a portion (or upper portion) of the support member 220 may extend through a hole 147 formed in corner portions 142-1 to 142-4 of the housing 140. In another embodiment, the support member may be positioned adjacent to the boundary line between the side portion 141 and the corner portion 142 of the housing 140, and the support member may not extend through the corner portion 142 of the housing 140.

[0307] The first coil 120 can be electrically connected to the lower elastic member 160. The first coil 120 can be electrically connected to the first lower elastic unit 160-1 and the second lower elastic unit 160-2 via solder or conductive adhesive.

[0308] The first coil 120 can be directly connected or coupled to a corresponding second inner frame of the second inner frame 161 of the first lower elastic unit 160-1 and the second lower elastic unit 160-2 via solder or conductive adhesive. For example, the second inner frame 161 of the first lower elastic unit 160-1 may include a first coupling 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 coupling portion 43b coupled to the other end of the first coil 120. Each of the first coupling portion 43a and the second coupling portion 43b may have a groove 8a for guiding the coil 120.

[0309] The first support member 220A can be disposed on the first corner portion 142-1 of the housing 140 and can be connected to the first upper elastic unit 150-1. The first support member 220A can be connected to the first elastic member 60A. The second support member 220B can be disposed on the second corner portion 142-2 of the housing 140 and can be connected to the second upper elastic unit 150-2. The second support member 220B can be connected to the second elastic member 60B. The third support member 220C can be disposed on the third corner portion 142-3 of the housing 140 and can be connected to the third upper elastic unit 150-3. The third support member 220C can be connected to the third elastic member 60C. The fourth support member 220D can be disposed on the fourth corner portion 142-4 of the housing 140 and can be connected to the fourth upper elastic unit 150-4. The fourth support member 220D can be connected to the fourth elastic member 60D.

[0310] The first terminal B1 of the circuit board 190 is electrically connected to the first support member 220A, and the second terminal B2 of the circuit board 190 is electrically connected to the second support member 220B. The third terminal B3 of the circuit board 190 is electrically connected to the third support member 220C, and the fourth terminal B4 of the circuit board 190 is electrically connected to the fourth support member 220D.

[0311] Each of the first support member 220A to the fourth support member 220D can be electrically connected to a corresponding terminal of the terminals 251-1 to 251-n (n is a natural number greater than 1) of the circuit board 250.

[0312] For example, power signals VDD and GND can be supplied to the first support member 220A and the second support member 220B through the first and second terminals (e.g., 251-1 and 251-2) of circuit board 250. Power signals VDD and GND can be supplied to the first terminal B1 and the second terminal B2 of circuit board 190 through the first upper elastic unit 150-1 and the second upper elastic unit 150-2. The first position sensor 170 can receive power signals VDD and GND through the first terminal B1 and the second terminal B2 of circuit board 190.

[0313] For example, the first terminal B1 of the circuit board 190 can be one of the VDD terminal and the GND terminal, and the second terminal B2 of the circuit board 190 can be the other of the VDD terminal and the GND terminal.

[0314] Furthermore, the clock signal SCL and the data signal SDA can be supplied to the third support member 220C and the fourth support member 220D through the third terminal 251-3 and the fourth terminal 251-4 of the circuit board 250, and the clock signal SCL and the data signal SDA can be supplied to the third terminal B3 and the fourth terminal B4 of the circuit board 190 through the third upper elastic unit 150-3 and the fourth upper elastic unit 150-4. The first position sensor 170 can receive the clock signal SCL and the data signal SDA through the third terminal B3 and the fourth terminal B4 of the circuit board 190.

[0315] For example, the power signal VDD can be supplied to the first position sensor 170 through the first terminal 251-1 of the circuit board 250, the first support member 220A, the first upper elastic unit 150-1, and the first terminal B1 of the circuit board 190. The power signal GND can be supplied to the first position sensor 170 through the second terminal 251-2 of the circuit board 250, the second support member 220B, the second upper elastic unit 150-2, and the second terminal B2 of the circuit board 190.

[0316] For example, the clock signal SCL can be supplied to the first position sensor 170 through the third terminal 251-3 of circuit board 250, the third support member 220C, the third upper elastic unit 150-3, and the third terminal B3 of circuit board 190. The data signal SDA can be supplied to the first position sensor 170 through the fourth terminal 251-4 of circuit board 250, the fourth support member 220D, the fourth upper elastic unit 150-4, and the fourth terminal B4 of circuit board 190.

[0317] Each of the fifth terminal B5 and the sixth terminal B6 of the circuit board 190 can be connected or coupled to the second outer frame 162-1 of the corresponding one of the first lower elastic unit 160-1 and the second lower elastic unit 160-2.

[0318] The second outer frame 162-1 of the first lower elastic unit 160-1 may include a first connecting portion 81a, to which the fifth terminal B5 of the circuit board 190 is connected via solder or conductive adhesive. The second outer frame 162-1 of the second lower elastic unit 160-2 may include a second connecting portion 81b, to which the sixth terminal B6 of the circuit board 190 is connected via solder or conductive adhesive.

[0319] For example, the second outer frame 162-1 of the first lower elastic unit 160-1 may include a first hole (or first groove) 82a in which the fifth terminal B5 of the circuit board 190 is inserted or disposed, and the second outer frame 162-1 of the second lower elastic unit 160-2 may include a second hole (or second groove) 82b in which the sixth terminal B6 of the circuit board 190 is inserted or disposed.

[0320] For example, although each of the first hole 82a and the second hole 82b can be formed through the second outer frame 162-1 and can have an opening at one side of the second outer frame 162-1, this disclosure is not limited thereto. In another embodiment, each of the first hole 82a and the second hole 82b may not have an opening at one side of the second outer frame 162-1.

[0321] Since 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) in the second outer frame 162-1 of the first lower elastic unit 160-1, the fifth terminal B5 (or the sixth terminal B6) is connected to the first bonding portion 81a (or the second bonding portion 81b) in which the first groove 82a (or the second groove 82b) is formed via solder or conductive adhesive, the connection area can be increased, thereby increasing the connection force between the terminal and the bonding portion and improving the solderability between the terminal and the bonding portion.

[0322] Reference Figure 12 One end (e.g., lower end or lower surface) of each of the fifth terminal B5 and the sixth terminal B6 can be positioned below the lower end or lower surface of the second outer frame 162-1 of the first lower elastic unit 160-1 and the second lower elastic unit 160-2. Because Figure 12 The view is from below, so the lower surface of each of the fifth terminal B5 and the sixth terminal B6 can be shown positioned below the lower end or lower surface of the second outer frame 162-1. This is done to improve the solderability between one end of each of the fifth terminal B5 and the sixth terminal B6 and the first connecting portion 81a of the first lower elastic unit 160-1 and the second connecting portion 81b of the second lower elastic unit 160-2.

[0323] Reference Figure 12 The housing 140 may have a recess 31 that is recessed from the lower surface of the first side portion 141-1. For example, the bottom surface of the recess 31 in the housing 140 may have a height difference relative to the lower surface of the housing 140 in the optical axis direction. For example, the bottom surface of the recess 31 in the housing 140 may be positioned higher than the lower surface of the housing 140.

[0324] The groove 31 in the housing 140 can overlap with the first connecting portion 81a of the first lower elastic unit 160-1 and the second connecting portion 81b of the second lower elastic unit 160-2 in the optical axis direction. Furthermore, the groove 31 in the housing 140 can overlap with the holes 82a and 82b in the second outer frame 162-1 of the first lower elastic unit 160-1 and the second lower elastic unit 160-2 in the optical axis direction.

[0325] By means of the recess 31 in the housing 140, the surface area of ​​the fifth terminal B5 and the sixth terminal B6 of the circuit board 190 exposed through the housing can be increased, and space for mounting solder or conductive adhesive can be ensured. Therefore, solderability can be improved and the distance that the solder protrudes downward from the lower surface of the second outer frame 162-1 can be reduced, thereby suppressing or preventing spatial interference with the second coil 230, circuit board 250 or base 210 located below the lower elastic unit.

[0326] The lower surface 11c of the first magnet 130 disposed in the seating groove 141a in the housing 140 can be positioned lower than the lower surface of the housing 140 and the lower surfaces of the second outer frames 162-1 to 162-3 of the first lower elastic unit 160-1 and the second lower elastic unit 160-2. In another embodiment, the height of the lower surface 11c of the first magnet 130 can be higher than or equal to the height of the lower surface 11c of the housing 140.

[0327] In order to separate the first magnet 130 from the second coil 230 and the circuit board 250, the other end of the support member 220 can be connected to the elastic member 60 at a level below the lower surface 11c of the first magnet 130.

[0328] In embodiments where the lower surface 11c of the first magnet 130 is positioned at a level equal to or higher than the lower surface 11c of the housing 140, the other end of the support member 220 may be connected to the elastic member 60 at a level lower than the lower surface of the housing 140 or the lower elastic member 160.

[0329] Each of the upper elastic member 150, lower elastic member 160, elastic member 60, and support member 220 may include a conductive material. Each of the upper elastic member 150, lower elastic member 160, elastic member 60, and support member 220 may include a metallic material. Each of the upper elastic member 150, lower elastic member 160, elastic member 60, and support member 220 may be a non-magnetic material.

[0330] Each support member in support member 220 can be implemented as a member capable of supporting an object. For example, each support member in support member 220 can be a suspension wire or a helical spring. In another embodiment, each support member in support member 220 can be a helical spring formed from wound wire.

[0331] Reference Figure 13a , Figure 13b , Figure 17a and Figure 17c The base 210 may be disposed below the cover member 300 or the housing 140. The base 210 may be spaced apart from the housing 140. The base 210 may be disposed below the lower elastic member 160. The base 210 may be disposed below the circuit board 250.

[0332] The base 210 may have an opening 401 corresponding to the opening 102 in the coil holder 110 and / or the opening 201 in the housing 140. The base 210 may have a shape corresponding to or consistent with the cover member 300, such as a square shape. For example, the opening 401 in the base 210 may be a through hole formed through the base 210 in the optical axis direction.

[0333] The base 210 may include a stepped portion (or protrusion) 211 to which adhesive is applied when the cover member 300 is fixed to the base 210 by adhesive. Here, the stepped portion 211 may guide the side plate 302 of the cover member 300, which is connected to the upper side of the base. The lower end of the side plate 302 of the cover member 300 may contact the stepped portion 211. The stepped portion 211 of the base 210 may be bonded or connected to the lower end of the side plate 302 of the cover member 300 via adhesive.

[0334] A support portion 255 may be provided in the area of ​​the base 210 facing the terminal member 253—where terminals 151-1 to 251-n of the circuit board 250 are located. The support portion 255 can support the terminal member 253 of the circuit board 250 where terminals 251-1 to 251-n of the circuit board 250 are formed. (See reference...) Figure 13bFor example, the support portion 255 may include a protrusion (or "protrusion") projecting downward from the lower surface 210B of the base 210. For example, the support portion 255 may have the form of a groove recessed from the outer surface of the base 210. In another embodiment, the support portion 255 may not be recessed from the outer surface of the base 210. The base 210 may include the same number of support portions as the terminal member 253.

[0335] The base 210 may have at least one seating groove 215-1 and 215-2 disposed or formed in the upper surface 210A of the base 210. The second position sensor 240 may be disposed in the seating groove 215-1 and 215-2 in the base 210. For example, each of the first sensor 240a and the second sensor 240b may be disposed in a corresponding one of the two seating grooves 215-1 and 215-2 of the base 210.

[0336] The upper surface of the base 210 surrounding the opening 401 may be provided with a protrusion 19, which connects to the opening 50A in the circuit board 250 and the opening 230A in the circuit component 231. For example, the protrusion 19 may protrude upward from the upper surface of the base 210.

[0337] The base 210 may include a clearance portion 212 configured to avoid spatial interference with the support member 220 and / or the elastic member 60. The clearance portion 212 may be located at a corner of the base 210. The clearance portion 212 may be a recessed groove from the outer surface of the base 210. The clearance portion 212 may be open at the upper and lower surfaces of the base 210. The clearance portion 212 may have a shape formed by chamfering the corner of the base 210. The clearance portion 212 may overlap with the support member 220 in the optical axis direction. The clearance portion 212 may overlap with at least a portion of the elastic member 60, such as the second connector 62, in the optical axis direction. The clearance portion 212 may overlap with at least a portion of the connector 63 of the elastic member 60 in the optical axis direction. At least a portion of the elastic member 60 may overlap with the clearance portion 212 in a direction perpendicular to the optical axis. The clearance portion 212 may include a plurality of clearance portions 212A to 212D disposed on the corner portion of the base 210. With the aid of the clearance portion 212, the elastic member 60 can be easily bent or moved, thereby making it easy to disperse the stress applied from the support member 220.

[0338] The base 210 may include a connector 217 connected to the first connector 61. The connector 217 may be in the form of a recess. For example, the connector 217 may be a recess formed from the upper surface 210A of the base 210. For example, the connector 217 may be formed at a corner portion of the base 210. The connector 217 may be adjacent to or abut against the clearance portion 212. The base 210 may include the connector 217 corresponding to the connection regions 61A and 61B of the first connector 61 of the elastic member 60.

[0339] The connector 217 of the base 210 may include a bottom surface 217A having a height difference relative to the upper surface 210A of the base 210, and a side surface 217B disposed between the bottom surface 217A and the upper surface 210A. The connector 217 of the base 210 may include an opening opening toward the clearance portion 212. The first connector 61 may be disposed in a groove 217 in the base 210 and may be connected to the groove 217. For example, an adhesive may be disposed in the groove 217, and the first connector 61 may be connected to the groove 217 in the base via the adhesive.

[0340] Since the first connector 61 is disposed in the groove 217 in the base 210, the connection force between the first connector 61 and the base 210 can be increased, and the warping or rotation of the elastic member 60 in the direction perpendicular to the optical axis can be prevented or suppressed.

[0341] The base 210 may include a protrusion 218 configured to prevent the circuit board 250 from separating from or warping the upper surface of the base 210. The protrusion 218 may be used to guide the assembly of the circuit board 250. The protrusion 218 may protrude from the peripheral edge of the upper surface of the base 210. The peripheral edge of the circuit board 250 may contact the protrusion 218. To facilitate soldering between the first connector 61 and the pads 259 of the circuit board 250, a groove 218A may be formed in a portion of the protrusion 218.

[0342] At least a portion of the protrusion 218 may be positioned adjacent to the groove 217 in the base 210 to prevent the adhesive configured to attach the first connector 61 to the groove 217 from overflowing.

[0343] Connector 63 may be spaced apart from the side surface 217B of the groove 217 in the base 210. For example, the width K4 of connector 63 may be smaller than the width K5 of the groove 217 in the base 210. The width K5 may be the length of the first connector 61 in the longitudinal direction or in the width direction. For example, one end 66 of connector 63 that engages or connects with the first connector 61 may be spaced apart from the side surface 217B of the groove 217. Therefore, spatial interference between connector 63 and base 210 can be avoided, ensuring that a space is constructed to accommodate elastic deformation of connector 63 in the direction perpendicular to the optical axis, and easily dissipating stress applied from support member 220.

[0344] The base 210 may include an inclined surface 217C formed on the bottom surface 217A of the groove 217. The inclined surface 217C may be a chamfered surface. The inclined surface 217C may be disposed between the bottom surface 217A of the groove 217 and the clearance portion 212.

[0345] The inclined surface 217C can be positioned at a location corresponding to one end of the connector 63 that connects to the first connector 61. The inclined surface 217C can be positioned below one end 66 of the connector 63 that meets or connects to the first connector 61. For example, the inclined surface 217C can overlap with one end 66 of the connector 63 that meets or connects to the first connector 61 in the optical axis direction. Based on an imaginary plane parallel to the bottom surface 217A, the angle of the inclined surface 217C can be in the range of 30° to 60°. In another embodiment, the angle of the inclined surface 217C can be in the range of 40° to 50°. In yet another embodiment, the angle of the inclined surface 217C can be 40° to 45°. When the elastic member 60 undergoes elastic deformation in the optical axis direction, the inclined surface 217C can be used to prevent or suppress interference, collision, or friction between the connector 63 of the elastic member 60 and the base 210, thereby preventing breakage of the connector 63.

[0346] The second coil 230 can be configured to face the first magnet 130 in the optical axis direction. For example, the second coil 230 can be located below the housing 140. The second coil 230 can be located below the lower elastic member 160. For example, the second coil 230 can be located on the circuit board 250.

[0347] The second position sensor 240 can be disposed below the circuit board 250. For example, the second position sensor 240 can be disposed between the lower surface of the circuit board 250 and the base 210. For example, the second position sensor 240 can be disposed in the mounting recesses 215-1 and 215-2 in the base located below the circuit board 250.

[0348] For example, the second position sensor 240 can detect the displacement or position of the OIS moving unit (e.g., housing 140). For example, the second position sensor 240 can detect the displacement or position of the first magnet 130. The second position sensor 240 can detect the magnetic field strength of the first magnet 130.

[0349] The second position sensor 240 may include a first sensor 240a and a second sensor 240b. The first sensor 240a and the second sensor 240b can detect the displacement or position of the OIS moving unit in a direction perpendicular to the optical axis.

[0350] The first sensor 240a may face or overlap with one of the first magnet units 130-1 to the fourth magnet unit 130-4 (e.g., 130-3) in the optical axis direction. For example, the first sensor 240a may face or overlap with one of two magnet units (e.g., 130-1 and 130-3) that are opposite each other in the first diagonal direction (or in another embodiment, in the X-axis direction). For example, the first sensor 240a may detect the magnetic field strength of the magnet unit (e.g., 130-3) and may output a first output signal.

[0351] For example, the second sensor 24b may face or overlap with one of two magnet units (e.g., 130-4) that are opposite each other in the second diagonal direction (or, in another embodiment, in the X-axis direction). For example, the second sensor 240b may detect the magnetic field strength of the magnet unit (e.g., 130-4) and may output a second output signal. The first and second output signals can be used to detect the displacement or position of the OIS moving unit.

[0352] The circuit board 250 may be disposed below the housing 140. For example, the circuit board 250 may be disposed on the base 210. The circuit board 250 may be disposed below the circuit member 251. The circuit board 250 may be disposed on the upper surface 210A of the base 210. The circuit board 250 may include openings 50A corresponding to openings 102 in the coil holder 110, openings 201 in the housing 140, and / or openings 401 in the base 210. The openings 50A in the circuit board 250 may be in the form of through holes. The circuit board 250 may have the same or corresponding shape as the upper surface 210A of the base 210, for example, a square shape.

[0353] The circuit board 250 may include a body 252 disposed on the upper surface 210A of the base 210 and at least one terminal member 253 bent at the edge of the body 252. The terminal member 253 may alternatively be referred to as a "terminal portion".

[0354] Terminal member 253 may include a plurality of terminals 251-1 to 251-n (n is a natural number greater than 1) configured to receive electrical signals from the outside. For example, circuit board 250 may include two terminal members positioned opposite each other with body 252 placed therebetween. These two terminal members may be located on two opposite sides of body 252. Terminal member 253 may alternatively be referred to as "terminal portion", "extension portion" or "bent portion".

[0355] The second coil 230 may be disposed below the coil holder 110. The second coil 230 may be disposed below the housing 140. The second coil 230 may correspond to, face, or overlap with the first magnet 130 in the optical axis direction. For example, the second coil 230 may include a plurality of coil units 230-1 to 230-4 corresponding to magnet units 130-1 to 130-4, respectively. The second coil 230 may move the OIS moving unit (e.g., housing 140) in a direction perpendicular to the optical axis by means of the electromagnetic force generated due to its interaction with the first magnet 130. The OIS moving unit may move in a direction perpendicular to the optical axis or may be tilted relative to the optical axis.

[0356] The OIS moving unit may include an AF moving unit and a housing 140. According to an embodiment, the OIS moving unit may also include a first magnet 130. For example, the fixing unit may also include a base 210. Furthermore, the fixing unit may include components coupled to the base 210. For example, the fixing unit may include at least one of a circuit board 250, a second position sensor 240, a second coil 230, and a circuit component 231. The OIS moving unit may be configured to be spaced apart from the fixing unit via a support member 220 and may be supported by the support member 220.

[0357] Each of the multiple coil units 230-1 to 230-4 may face or overlap with a corresponding magnet unit among the magnet units 130-1 to 130-4 in the optical axis direction.

[0358] The second coil 230 can be disposed on the circuit board 250. 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 also be referred to as a "substrate," "circuit board," or "coil board." The circuit member 231 may include an opening 230A that faces or overlaps with an opening 50A in the circuit board 250 or an opening 401 in the base 210. The opening 230A may be formed through the circuit member 231 in the optical axis direction. For example, four coil units may be disposed or formed at the corners or corner regions of the polygonal (e.g., rectangular) circuit member 231.

[0359] For example, the second coil 230 may include two coil units 230-1 and 230-3 for the first diagonal direction and two coil units 230-2 and 230-4 for the second diagonal direction. For example, the two coil units 230-1 and 230-3 may be disposed in two corner regions of the circuit member 231 that are opposite each other in the first diagonal direction, and the remaining two coil units 230-2 and 230-4 may be disposed in two other corner regions of the circuit member 231 that are opposite each other in the second diagonal direction. The first diagonal direction may be a direction intersecting the second diagonal direction. For example, the first diagonal direction may be a direction perpendicular to the second diagonal direction.

[0360] In another embodiment, the second coil 230 may include a coil unit for a first diagonal direction and a coil unit for a second diagonal direction. In another embodiment where the magnet unit is disposed on the side portions 141-1 to 141-4 of the housing 140, the second coil 230 may include two coil units opposite each other in a second direction (X-axis direction) and two coil units opposite each other in a third direction (Y-axis direction).

[0361] A power signal or drive signal from circuit board 250 can be supplied to the second coil 230. The power signal or drive signal supplied to the second coil 230 can be a DC signal or an AC signal, or can include both DC and AC components, and can be current-type or voltage-type.

[0362] By means of the interaction between the magnet units 130-1 to 130-4 and the coil units 230-1 to 230-4 supplied with drive signals, the housing 140 can move in a direction perpendicular to the optical axis, thereby performing hand shakiness correction. For example, the housing 140 can move in a second direction and / or a third direction, such as along the X-axis and / or Y-axis.

[0363] Coil units 230-1 to 230-4 can be electrically connected to corresponding terminals 251-1 to 251-n of circuit board 250 in order to receive drive signals from circuit board 250.

[0364] The circuit board 250 may include pads 27a, 27b, 28a and 27d that are conductively connected to coil units 230-1 to 230-4. Here, pads 27a, 27b, 27c and 27d may alternatively be referred to as “terminals” or “bonding portions”.

[0365] For example, two coil units 230-1 and 230-3 can be connected in series with each other. For example, coil units 230-1 and 230-3 connected in series can be electrically connected at one end to a first pad 27a of circuit board 250 and at the other end to a second pad 27b of circuit board 250. Furthermore, for example, each of additional coil units 230-2 and 230-4 can be connected in series with each other. Coil units 230-2 and 230-4 connected in series can be electrically connected at one end to a third pad 27c of circuit board 250 and at the other end to a fourth pad 27d of circuit board 250.

[0366] The first pad 27a and the second pad 27b of the circuit board 250 can be electrically connected to two corresponding terminals of the circuit board 250, and coil units 230-1 and 230-3, which are connected in series with each other via two corresponding terminals of the circuit board 250, can be provided with a first drive signal. The third pad 27c and the fourth pad 27d of the circuit board 250 can be electrically connected to two other corresponding terminals of the circuit board 250, and coil units 230-2 and 230-4, which are connected in series with each other via two other corresponding terminals of the circuit board 250, can be provided with a second drive signal.

[0367] Reference Figure 13bThe circuit component 231 may include pads 38a to 38d corresponding to pads 27a to 27d of the circuit board 250, respectively. Pad 38a may be electrically connected to one end of coil units 230-1 and 230-3 connected in series with each other (e.g., one end of the first coil unit 230-1), and pad 38b may be electrically connected to the other end of coil units 230-1 and 230-3 connected in series with each other (e.g., one end of the third coil unit 230-3). Pad 38c may be electrically connected to one end of coil units 230-2 and 230-4 connected in series with each other (e.g., one end of the second coil unit 230-2), and pad 38d may be electrically connected to the other end of coil units 230-2 and 230-4 connected in series with each other (e.g., one end of the fourth coil unit 230-4).

[0368] Each of the pads 38a to 38d of the circuit component 231 can be electrically connected to a corresponding pad of the pads 27a to 27d of the circuit board 250. For example, the pads 38a to 38d of the circuit component 231 can be electrically connected to the pads 27a to 27d of the circuit board 250 via solder or conductive adhesive, respectively.

[0369] The base 210 may include a recess 214 (or “avoidance recess”) formed in the upper surface 210A of the base 210 to avoid spatial interference with the solder (or conductive adhesive) that conductively connects the pads 38a to 38d of the circuit components 231 to the pads 27a to 27d of the circuit board 250. The recess 214 may face or overlap with the solder in the optical axis direction. The recess 214 may be recessed from the upper surface 210A of the base 210 and may prevent breakage of the solder or the base 210 due to collision between the base 210 and the solder caused by external impact.

[0370] exist Figure 13a and Figure 13b In this circuit, coil units 230-1 to 230-4 can be formed at a circuit component 231 that is separate from the circuit board 250, and coil units 230-1 to 230-4 can be implemented in the form of a circuit pattern, such as an FP coil.

[0371] The circuit component 231 may have a clearance groove 24 for avoiding spatial interference with the fifth terminal B5 and the sixth terminal B6 of the circuit board 190. The clearance groove 24 may be formed in a side portion of the circuit component 231. For example, the clearance groove 24 may be positioned between the first coil unit 230-1 and the second coil unit 230-2.

[0372] To avoid spatial interference with the support member 220, the circuit member 231 may include a clearance portion 23. The clearance portion 23 may be located at a corner or edge of the circuit member 231. For example, the clearance portion 23 may have the form of a groove formed in the edge of the circuit member 231. For example, the clearance portion 23 may be formed by chamfering the edge of the circuit member 231. In another embodiment, the clearance portion 23 may have the form of a through hole through which the support member 220 extends.

[0373] In another embodiment, circuit component 231 may be omitted, and coil units 230-1 to 230-4 may be implemented as a ring coil block and may be disposed on circuit board 250.

[0374] In another embodiment, circuit component 231 may be omitted, and coil units 230-1 to 230-4 may be integrally formed with circuit board 250. Coil units 230-1 to 230-4 may be implemented as circuit patterns (e.g., FP coils) or conductive layers formed on circuit board 250. In another embodiment, circuit board 250 and circuit component 231 may be collectively referred to as "circuit component" or "substrate".

[0375] Each of the first sensor 240a and the second sensor 240b may be a Hall sensor. Each of the first sensor 240a and the second sensor 240b may be a sensor capable of detecting magnetic field strength. In another embodiment, each of the first sensor 240a and the second sensor 240b may be implemented as a driver IC including a Hall sensor. The terminal member 253 of the circuit board 250 may be provided with terminals 251-1 to 251-n. Signals SCL, SDA, VDD, and GND for data communication with the first position sensor 190 can be transmitted and received via the plurality of terminals 251-1 to 251-n provided on the circuit board 250.

[0376] Drive signals can be supplied to the first sensor 240a and the second sensor 240b via multiple terminals 251-1 to 251-n, and the signals output from the first sensor 240a and the second sensor 240b can be output to the outside via multiple terminals 251-1 to 251-n of the circuit board 250.

[0377] According to one embodiment, circuit board 250 may be a printed circuit board or a flexible printed circuit board. In another embodiment, lens driving device 100 may include a plurality of terminals formed on the surface of base 210 by surface electrode technology in place of circuit board 250 or terminals of circuit board 250.

[0378] The circuit board 250 may include clearance portions 250a for avoiding spatial interference with the support members 220. The clearance portions 250a may be positioned corresponding to, facing, or overlapping the support members 220A to 220D. The number of clearance portions 250a may be equal to the number of support members 220A to 220D. The clearance portions 250a may be positioned adjacent to the edges or corners of the circuit board 250. The clearance portions 250a of the circuit board 250 may have the form of a groove formed in the edge of the body 252 of the circuit board 250. For example, the clearance portions 250a of the circuit board 250 may be formed by chamfering the edge of the body 252 of the circuit board 250. The clearance portions 250a of the circuit board 250 may face or overlap the support members 220 in the optical axis direction. Furthermore, the clearance portion 250a of the circuit board 250 may overlap with the support member 220 in a direction perpendicular to the optical axis. In another embodiment, the clearance portion 250a may be a through hole formed through the circuit board 250.

[0379] The circuit board 250 may include a protrusion (or extension) connected to the base 210. The protrusion 256 may extend outward from the peripheral edge or lateral side of the body 252 of the circuit board 250 toward the outer surface of the base 210. At least a portion of the protrusion 256 may be bent at the edge of the body 252 of the circuit board 250. The base 210 may include a recess 216 for the protrusion 256 of the circuit board 250 to be disposed therein or inserted. The recess 216 may be recessed outward from the outer surface of the base 210. The protrusion 256 of the circuit board 250 may engage with the recess 216 of the base 210.

[0380] The circuit board 250 may include pads 259 electrically connected to the resilient member 60. The pads 259 may be disposed on at least one of the side surface and the bottom surface of the circuit board 250. For example, the pads 259 may be positioned in a corner region of the circuit board 250. In another embodiment, the pads 259 may be positioned on a lateral side of the circuit board 250.

[0381] For example, pad 259 may be positioned as a clearance portion 250a adjacent to circuit board 250. For example, circuit board 250 may include pads 259A to 259D corresponding to elastic units 60A to 60D.

[0382] For example, pad 259 may be formed in a recess recessed from the lateral surface of circuit board 250. Pad 259 may include a first portion (or a first region) disposed on the lower surface of circuit board 250. The first portion of pad 259 may be exposed from the lower surface of circuit board 250. Pad 259 may include a second portion (or a second region) disposed on the lateral surface of circuit board 250. For example, the second portion of pad 259 may be in the form of a via. Alternatively, the second portion of pad 259 may be in the form of a recess recessed from the peripheral edge (or lateral surface) of circuit board 250. In another embodiment, pad 259 may include a third portion (or a third region) disposed on the upper surface of circuit board 250.

[0383] The elastic units 60A to 60D can be electrically connected to the pads 259A to 259D of the circuit board 250 via solder 80 or conductive adhesive, respectively. The solder 80 or conductive adhesive can be disposed on the pads 259 of the circuit board 250 and the first connector 61A of the elastic units 60A to 60D. The solder 80 or conductive adhesive can be connected to the pads 259 of the circuit board 250 and the first connector 61A of the elastic units 60A to 60D.

[0384] The circuit board 250 may include conductive patterns or lines for conductively connecting pads 259A to 259D to terminals 251. Solder 80 or conductive adhesive may be disposed on or attached to at least one of the first, second, or third portions of the pads 259.

[0385] At least a portion of the circuit board 250 (or circuit member 231) may overlap with the first connector 61 of the elastic member 60 in the optical axis direction. A portion of the circuit board 250 (or circuit member 231) may cover the first connector 61 from above, thereby preventing foreign objects from entering the lens drive device 100.

[0386] In another embodiment, the circuit board (or circuit component 231) may not overlap with the first connector 61 of the elastic component 60 in the optical axis direction.

[0387] In this implementation, since the implementation is configured to supply a drive signal directly from the first position sensor 170 to the first coil 120, the number of support members can be reduced and the conductive connection structure can be simplified compared to the case where a drive signal is supplied directly to the first coil 120 via the circuit board 250.

[0388] Furthermore, since the first position sensor 170 can be implemented as a driver IC capable of detecting temperature, the accuracy of AF operation can be improved, regardless of temperature changes, by compensating the output of the Hall sensor to minimize its response to temperature changes or by compensating the output of the Hall sensor to change linearly with temperature changes.

[0389] The cover member 300, combined with the base 210, defines a receiving space in which the coil frame 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 150 can be accommodated.

[0390] The cover member 300 may include an upper plate 301 and a side plate 302 connected to the upper plate 301. For example, the cover member 300 may have the form of a box that is open at its lower surface. The lower portion of the cover member 300 (e.g., the lower end of the side plate 302) may be attached to the base 210. The upper plate 301 of the cover member 300 may have a polygonal shape, such as a square shape, an octagonal shape, etc.

[0391] The upper plate 301 of the cover member 300 may have an opening 303 that exposes a lens (not shown) coupled to the coil holder 110 to external light. The cover member 300 may be made of a non-magnetic material (e.g., stainless steel) to prevent the cover member 300 from being attracted to the first magnet 130 during OIS operation. In another embodiment, the cover member 300 may be made of a magnetic material and may be used as a magnetic yoke to increase the electromagnetic force between the first coil 120 and the first magnet 130.

[0392] Reference Figures 15 to 16 The first magnet (e.g., 130-1) can be configured such that the lateral length of the first magnet (e.g., 130-1) first increases and then decreases in the direction from the first surface 11a of the first magnet (e.g., 130-1) toward the second surface 11b of the first magnet (e.g., 130-1).

[0393] For example, the first magnet 130 may include a first portion Q1 and a second portion Q2, wherein the lateral length L1 of the first portion Q1 increases in the direction from the first surface 11a of the first magnet 130 toward the second surface 11b of the first magnet (e.g., 130-1), and the lateral length L2 of the second portion Q2 decreases in the direction from the first surface 11a toward the second surface 11b. The first portion Q1 of the first magnet 130 may include or be adjacent to the first surface 11a. The second portion Q2 of the first magnet 130 may include or be adjacent to the second surface 11b.

[0394] The reason for the reduction in the lateral length L2 of the second portion Q2 of the first magnet 130 is that the first magnet 130 is disposed on the corner portions 142-1 to 142-4 of the housing 140. The reason for the increase in the length of the first portion Q1 of the first magnet 130 is to prevent the first magnet 130 disposed in the sitting portion 141a in the housing 140 from separating into the housing 140. Since the lateral length L1 of the first portion Q1 decreases in the direction from the second surface 11b toward the first surface 11a, the magnetic field interference between the first magnet 130 and the second magnet 180, as well as the magnetic field interference between the first magnet 130 and the third magnet 185, can be reduced.

[0395] The length d1 of the first part Q1 in the direction from the first surface 11a to the second surface 11b can be less than the length d2 (d1 < d2) of the second part Q2 of the first magnet 130 in the direction from the first surface 11a to the second surface 11b. This is because when d1 > d2 is true, the surface area of ​​the first surface 11a decreases, and therefore the electromagnetic force generated by the interaction between the first coil 120 and the first magnet 130 decreases, making it impossible to obtain the desired electromagnetic force.

[0396] For example, the first terminals B1 to the fourth terminals B4 of the circuit board 190 can be positioned above the upper surface 11d of the first magnet 130. For example, the fifth terminal B5 and the sixth terminal B6 of the circuit board 190 can be positioned between two magnet units 130-1 and 130-2, which are disposed on two corner portions 142-1 and 142-2 of the housing 140 adjacent to the first side portion 141-1 of the housing 140 where the first position sensor 170 is disposed.

[0397] The upper surface of the first position sensor 170 can be positioned above the upper surface 11d of the first magnet 130, and the lower surface of the first position sensor 170 can be positioned at a level equal to or higher than the upper surface 11d of the first magnet 130. In another embodiment, the lower surface of the first position sensor 170 can be positioned below the upper surface of the first magnet 130.

[0398] The first terminal B1 of the circuit board 190 may overlap with the first magnet 130-1 disposed on 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 may overlap with the first magnet 130-2 disposed on the second corner portion 142-2 of the housing 140 in the optical axis direction. At the initial position of the coil holder 110, the upper surface of the second magnet 180 (and / or the upper surface of the third magnet 185) may be positioned higher than the upper surface 11d of the first magnet 130, and the lower surface of the second magnet 180 (and / or the lower surface of the third magnet 185) may be positioned lower than the upper surface 11d of the first magnet 130. In another embodiment, the lower surface of the second magnet 180 (and / or the lower surface of the third magnet 185) may be positioned at a level higher than or equal to the upper surface 11d of the first magnet 130.

[0399] To reduce the length of the path along which power signals GND and VDD are transmitted to the first position sensor 170, the implementation can be constructed as follows.

[0400] First, since the first terminal B1 and the second terminal B2 of the circuit board 190, to which power signals GND and VDD are supplied, are conductively connected to the first support member 220A and the second support member 220B disposed on the two corner portions 142-1 and 142-2 of the housing 140 adjacent to the first side portion 141-1 where the first position sensor 170 is disposed, the path length can be reduced. Furthermore, since the first terminal B1 and the second terminal B2 of the circuit board 190 are disposed on the body portion S1 of the circuit board 190, the path length can be reduced. Additionally, since the first terminal B1 of the circuit board 190 is disposed at one end of the circuit board 190 to overlap 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 to overlap with the second corner portion 142-2 of the housing 140 in the optical axis direction, the path length can be reduced.

[0401] The distance (e.g., the shortest distance) between the first terminal B1 of the circuit board 190 and the first support member 220A can be less than the distance (e.g., the shortest distance) between the third terminal B3 of the circuit board 190 and the first support member 220A, and the distance (e.g., the shortest distance) between the fourth terminal B4 of the circuit board 190 and the first support member 220A. Furthermore, the distance (e.g., the shortest distance) between the second terminal B2 of the circuit board 190 and the second support member 220B can be less than the distance (e.g., the shortest distance) between the third terminal B3 of the circuit board 190 and the second support member 220B, and the distance (e.g., the shortest distance) between the fourth terminal B4 of the circuit board 190 and the second support member 220B.

[0402] Because the path is reduced for the reasons described above, the length of each of the first extension P1 and the second extension P2 can be reduced, and thus the resistance of the path (e.g., the resistance of the first upper elastic unit 150-1 and the second upper elastic unit 150-2) can be reduced.

[0403] Since each of the first upper elastic unit 150-1 connected to the first terminal B1 of the circuit board 190 and the second upper elastic unit 150-2 connected to the second terminal B2 of the circuit board 190 includes a first outer frame connected to the housing 140, but does not include the first inner frame 151 and the first frame connector, the resistance can be reduced compared to the second upper elastic unit 150-2 and the fourth upper elastic unit 150-4.

[0404] For the reasons described above, because the implementation reduces the length of the path along which the power signals GND and VDD are transmitted to the first position sensor 170, the resistance of the path (e.g., the resistance of the first upper elastic unit 150-1 and the second upper elastic unit 150-2) can be reduced, and therefore the amplitude of the power signals GND and VDD can be prevented from decreasing. Therefore, power consumption can be reduced, and the operating voltage of the driver IC of the first position sensor 170 can be lowered.

[0405] According to the embodiment, in order to facilitate soldering of the first extension portion P1 to the fourth extension portion P4 for conductive connection to the upper elastic units 150-1 to 150-4 and thereby improve solderability, the first terminal P1 to the sixth terminal P6 may be disposed on the first surface 19a of the circuit board 190.

[0406] If the first terminals B1 to the sixth terminals B6 are disposed on the second surface 19b of the circuit board 190, soldering may become difficult and solderability may deteriorate. Furthermore, foreign matter (e.g., contaminants) generated during soldering may enter the lens drive device, leading to malfunction of the lens drive device.

[0407] Because the third terminal B3 and the fourth terminal B4 are disposed between the first terminal B1 and the second terminal B2, and the circuit board 190 extends or protrudes toward 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 150-4 (e.g., the third extension portion P3 or the fourth extension portion P4) can pass through the circuit board 190 and be connected to the corresponding one of the third terminal B3 and the fourth terminal B4. The fifth terminal B5 and the sixth terminal B6 of the circuit board 190 can be disposed on the extension portion S2 of the circuit board 190 to facilitate connection with the lower elastic units 160-1 and 160-2.

[0408] The lens drive unit 100 may include a damper (not shown) disposed between the elastic member 60 and the base 210 (or circuit board 250), and coupled or attached to at least a portion of the elastic member 60 and at least a portion of the base 210. Here, the damper may be made of a material capable of absorbing shocks or vibrations, such as silicone. The damper may absorb or buffer vibrations of the OIS moving unit. The damper may suppress oscillations of the OIS moving unit during OIS operation and may be used to perform stable OIS operation. The damper may contact, couple, or attach to a portion of the support member 220. For example, the damper may contact, couple, or attach to at least one of the second connector 62 or connector 63 of the elastic member 60.

[0409] To achieve high-quality images, the size (e.g., weight) of the lens module mounted on the lens drive can be increased. In an OIS-type lens drive with a heavier lens module mounted on it (e.g., having a weight equal to or greater than 0.4 g), the wire-shaped support member may be subjected to higher stress or load. In particular, in a comparative example where the lower end of the support member 220 is connected to a fixing unit—e.g., base 210 or circuit board 250—the support member may break due to the stress or load transmitted to the lower end of the support member.

[0410] Because the implementation is configured such that the lower end of the support member 220, which is configured to support the OIS moving unit, is connected or coupled to the elastic member 60, even when a heavy lens module is installed, the impact or stress applied to the support member 220 can be dispersed by the elastic member 60, thereby preventing or suppressing the breakage of the support member 220 and ensuring the reliability of OIS operation.

[0411] Furthermore, since the upper end of the support member 220 can move up and down and the lower end of the support member 220 can also move up and down with the help of the elastic member 60, the breakage of the OIS moving unit caused by external impact can be reduced.

[0412] Furthermore, since the elastic member 60 is positioned below the circuit board 250, the length of the support member 220 connected to the elastic member 60 can be increased, thereby increasing the resistance of the support member 220, reducing the current intensity flowing through the support member 220, and thus reducing power consumption. In addition, when the length of the support member 220 is increased, the support member 220 can be easily bent or deformed in a direction perpendicular to the optical axis, thereby reducing the driving force required for OIS operation.

[0413] Furthermore, according to the embodiment, the upper end of the support member 220 connected to the upper elastic member 150 may be movable, and the lower end of the support member 220 connected to the elastic member 60 may also be movable. For example, one end (or upper end) of the support member 220 connected to the upper elastic member 150 may be movable along the optical axis or in a direction perpendicular to the optical axis. For example, the other end (or lower end) of the support member 220 connected to the elastic member 60 may be movable along the optical axis or in a direction perpendicular to the optical axis.

[0414] The second coil 230 can be positioned closer to the elastic member 60 than to the upper elastic member 150. The shortest distance between the second coil 230 and the elastic member 60 can be less than the shortest distance between the second coil 230 and the upper elastic member 150. The second coil 230 can be positioned closer to the lower end of the support member 220 connecting to the elastic member 60 than to the upper end of the support member 220 connecting to the upper elastic member 150. The shortest distance between the second coil 230 and the lower end of the support member 220 connecting to the elastic member 60 can be less than the shortest distance between the second coil 230 and the upper end of the support member 220 connecting to the upper elastic member 150.

[0415] The elastic coefficient of the elastic member 60 may be higher than that of the upper elastic member 150. For example, the elastic coefficient of the elastic member 60 in the Z-axis direction may be higher than that of the upper elastic member 150 in the Z-axis direction. For example, the elastic coefficient of the elastic member 60 in the X-axis direction (or Y-axis direction) may be higher than that of the upper elastic member 150 in the X-axis direction (or Y-axis direction).

[0416] Since the elastic coefficient of the elastic member 60, which is spaced at a shorter distance from the second coil 230 that generates the driving force, is set to be higher than that of the upper elastic member 160, a balance can be established between the elastic force acting on the upper end of the support member 220 and the elastic force acting on the lower end, thereby enabling stable OIS operation.

[0417] In another embodiment, the elastic coefficient of the elastic member 60 can be equal to the elastic coefficient of the upper elastic member 150. For example, the elastic coefficient of the elastic member 60 in the Z-axis direction can be equal to the elastic coefficient of the upper elastic member 150 in the Z-axis direction. The elastic coefficient of the elastic member 60 in the X-axis direction (or Y-axis direction) can be equal to the elastic coefficient of the upper elastic member 150 in the X-axis direction (or Y-axis direction).

[0418] For example, the elastic coefficient of the upper elastic member 150 can be in the range of 60% to 100% of the elastic coefficient of the elastic member 60. For example, the elastic coefficient of the upper elastic member 150 in the Z-axis direction can be in the range of 60% to 100% of the elastic coefficient of the elastic member 60 in the Z-axis direction. For example, the elastic coefficient of the upper elastic member 150 in the Y-axis direction (or X-axis direction) can be in the range of 60% to 100% of the elastic coefficient of the elastic member 60 in the X-axis direction (Y-axis direction).

[0419] Since the elastic coefficient of the upper elastic member 150 is set to 60% to 100% of the elastic coefficient of the elastic member 60, a balance can be established between the elastic force acting on the upper end of the support member 220 and the elastic force acting on the lower end of the support member 220 based on the distance to the second coil 230 that generates the driving force, thereby enabling stable OIS operation to be performed.

[0420] The elastic coefficient of the elastic member 60 in the Z-axis direction can be lower than that in the X-axis direction (or Y-axis direction). In the case of a lens drive device with a heavy lens, the elastic coefficient of the elastic member 60 in the Z-axis direction can be set to be lower than that in the X-axis direction (or Y-axis direction) to adequately withstand stress in the optical axis direction and allow the lens to move easily along the optical axis direction.

[0421] According to the embodiment, since both the upper and lower ends of the support member 220 are movable, when the OIS moving unit tilts, the degree of tilting can be reduced or tilting can be suppressed compared to the comparative example. In other words, it can provide an effect that counteracts the tilting of the OIS moving unit caused by the individual movement of the upper and lower ends of the support member 220.

[0422] The elastic member 60 can be of the leaf spring type, which is advantageous in dispersing impacts and can easily disperse the loads or stresses transmitted or applied to it.

[0423] Furthermore, the elastic member 60 may be conductive and may be used as a conductive member configured to allow current to flow between the support member 220 and the circuit board 250.

[0424] According to the implementation, since the magnetic field interference between the second magnet 180 and the third magnet 185 and the first magnet 130 is reduced, the reduction of the AF driving force caused by the magnetic field interference can be prevented, and therefore the desired AF driving force can be obtained even without the additional magnetic yoke.

[0425] As described above, the implementation method can reduce the number of support members, and therefore the size of the lens drive device can be reduced by means of the reduction in the number of support members. Since the number of support members is reduced and thus the resistance of the support members is reduced, current consumption can be reduced and the sensitivity of OIS operation can be improved.

[0426] Furthermore, since the number of support members is reduced, the thickness of the support members can be increased to achieve the same elasticity, and since the thickness of the support members is increased, the impact of external impacts on the OIS moving unit can be reduced.

For example, the main body 850 may be divided into a front shell 851 and a rear shell 852.

The sensing unit 740 can also generate sensing signals to control the operation of the terminal 200A. When the terminal 200A is, for example, a slider cellular phone, the sensing unit 740 can sense whether the slider cellular phone is on or off. Furthermore, the sensing unit 740 can sense the power supply from the power supply unit 790, the connection between the interface unit 770 and external devices, etc.

For example, display module 751 may include at least one of liquid crystal display, thin-film transistor liquid crystal display, organic light-emitting diode, flexible display, and 3D display.

[0467] The audio output module 752 can output audio data received from the wireless communication unit 710 in, for example, call signal receiving mode, call mode, recording mode, voice recognition mode or broadcast receiving mode, or it can output audio data stored in the memory unit 760.

[0469] The memory unit 760 can temporarily store programs for processing and control of the controller 780, as well as input / output data (e.g., telephone numbers, messages, audio data, still images, moving images, etc.). For example, the memory unit 760 can store images captured by the camera 721, such as pictures or moving images.

[0470] Interface unit 770 serves as a path to connect the lens driving device to an external device connected to terminal 200A. Interface unit 770 can receive power or data from external components and can transmit power or data to corresponding components within terminal 200A, or transmit data from within terminal 200A to external components.

[0472] The controller 780 may include a multimedia module 781 for multimedia playback. The multimedia module 781 may be implemented in the controller 180 or may be implemented separately from the controller 780.

[0473] The controller 780 can perform pattern recognition processing, which can recognize handwritten or drawing input performed on the touch screen as characters and images, respectively.

[0474] Instead of the controller 830 of the camera module 200, the controller 780 of the optical device 200A can send a clock signal SCL, a data signal SDA, and power signals VDD and GND for I2C communication with the first position sensor 170, and can receive the clock signal SCL and the data signal SDA from the first position sensor 170.
