[0077] In the following description, embodiments will become apparent with reference to the accompanying drawings. In the description of embodiments, it should be understood that when an element such as a layer (film), region, pattern, or structure is referred to as being "on" or "below" another element such as a substrate, layer (film), region, pad, or pattern, the terms "on" or "below" mean that the element is "directly" on or below the other element, or "indirectly" formed, although intermediate elements may also be present. Furthermore, it should be understood that the standard for "on" or "below" is based on the accompanying drawings. Additionally, the same reference numerals will denote the same elements through the description of the drawings.

[0078] In the following description, a lens driving device according to an embodiment will be described with reference to the accompanying drawings. For ease of description, a Cartesian coordinate system (x, y, z) will be used to describe the lens driving device according to the embodiment, but any other coordinate system may be used, and the embodiment is not limited to this coordinate system. In the drawings, the x-axis and y-axis are directions orthogonal to the z-axis, and the z-axis is the optical axis direction. The z-axis direction, which is the optical axis direction, may be referred to as the "first direction," the x-axis direction may be referred to as the "second direction," and the y-axis direction may be referred to as the "third direction."

[0079] A "shake compensation device" used in a small camera module installed in a mobile device (e.g., a smartphone or tablet PC) is a device configured to prevent the outline of a captured image from being blurred due to vibrations caused by the user's hand shaking when the image is captured.

[0080] In addition, an "autofocus device" is a device used to automatically focus the image of the subject onto the surface of an image sensor.

[0081] "Autofocus function" is defined as follows: by moving the lens module along the optical axis according to the distance to the subject to adjust the distance to the image sensor, the subject is focused onto the image sensor in order to obtain a sharp image of the subject. The term "autofocus" can be used interchangeably with "AF (autofocus)".

[0082] The “shake compensation function” mentioned below is defined as follows: moving or tilting the lens module in a direction orthogonal to the optical axis to eliminate shake (movement) caused by external forces in the image sensor. The term “shake compensation” can be used interchangeably with “optical image stabilization (OIS)”.

[0083] The image stabilization device and the autofocus device can be configured in various ways. According to an embodiment, the lens driving device can perform image stabilization and / or autofocus operations by moving an optical module consisting of at least one lens along a first direction or by moving the optical module relative to a plane defined by a second direction and a third direction orthogonal to the first direction.

[0084] Figure 1 yes Figure 1 An exploded perspective view of the lens driving device 100 shown, and Figure 2 yes Figure 1 An assembly perspective view of the lens drive unit excluding the cover component 300.

[0085] Reference Figure 1 and Figure 2 The lens driving device 100 includes a bobbin 110, a first coil 120, a magnet 130, a housing 140, an upper elastic member 150, a lower elastic member 160, and a sensing coil 170.

[0086] In addition, the lens drive device 100 may also include a support member 220, a second coil 230, an optical image stabilization (OIS) position sensor 240, and a circuit board 250.

[0087] In addition, the lens driving device 100 may also include a base 210 and a cover member 300.

[0088] First, the cover component 300 will be described.

[0089] The cover member 300 houses the spool 110, the first coil 120, the magnet 130, the housing 140, the upper elastic member 150, the lower elastic member 160, the sensing coil 170, the support member 220, the second coil 230, the OIS position sensor 240, and the circuit board 250 in a receiving space defined between the cover member and the base 210.

[0090] The cover member 300 may be in the form of a box with an open bottom and top portion and side walls, and the bottom of the cover member 300 may be coupled to the top of the base 210. The top portion of the cover member 300 may have a polygonal shape, such as a rectangular shape, an octagonal shape, etc.

[0091] The cover member 300 may have a central control area formed in its upper portion to expose a lens (not shown) coupled to the cable spool 110 to external light. Additionally, the hollow area in the cover member 300 may be provided with a window made of a light-transmitting material to prevent foreign objects (e.g., dust or moisture) from entering the interior of the camera module.

[0092] The cover member 300 may be formed of a non-magnetic material (e.g., SUS) to prevent the cover member from adhering to the magnet 130, but may be formed of a magnetic material to serve as a bonding agent.

[0093] Next, the spool 110 will be described.

[0094] Figure 3 It shows Figure 1Perspective view of the spool 110 shown.

[0095] Reference Figure 3 The spool 110 is located inside the housing 140 and can move in the first direction by the electromagnetic interaction between the coil 120 and the magnet 130.

[0096] Although not shown, the spool 110 may include a lens barrel (not shown) in which at least one lens is disposed, and the lens barrel may be coupled within the spool 110 in any of a variety of ways.

[0097] The spool 110 may have a hollow region for mounting a lens or lens barrel. The hollow region of the spool 110 may have the same shape as the lens or lens barrel to be mounted therein, and may have, for example, a circular shape, an elliptical shape, or a polygonal shape, but is not limited thereto.

[0098] The spool 110 may include: at least one upper support protrusion 113 disposed on the upper surface and coupled and fixed to the inner frame 151 of the upper elastic member 150; and at least one lower support protrusion (not shown) disposed on the lower surface and coupled and fixed to the inner frame 161 of the lower elastic member 160.

[0099] The spool 110 may have an upper avoidance groove 112, which is formed on the upper surface of the spool 110 in a region corresponding to or aligned with the frame connection portion 153 of the upper elastic member 150. Furthermore, the spool 110 may have a lower avoidance groove (not shown), which is formed on the lower surface of the spool 110 in a region corresponding to or aligned with the connection portion 163 of the lower elastic member 160. In another embodiment, the connection portion of the upper elastic member and the spool is designed not to interfere with each other; in this case, the upper and / or lower avoidance grooves on the spool may not be provided.

[0100] The spool 110 may have at least one groove (not shown) formed in its outer peripheral surface, in which a first coil 120 is disposed. The first coil 120 may be placed or positioned in the groove. Alternatively, the first coil 120 may be directly wound in the groove to rotate clockwise or counterclockwise about the optical axis OA. The shape and number of grooves may correspond to the shape and number of coils disposed on the outer peripheral surface of the spool 110. In another embodiment, the spool 110 may not have a coil placement groove, and the first coil 120 may be directly wound around the outer peripheral surface of the spool 110, or may be wound and secured.

[0101] Next, the first coil 120 will be described.

[0102] The first coil 120 may be a drive coil disposed on the outer peripheral surface of the tube 110 to electromagnetically interact with a magnet 130 disposed on the housing 140. A drive signal (e.g., a drive current) may be applied to the first coil 120 to generate an electromagnetic force due to the interaction between the first coil 120 and the magnet 130.

[0103] According to Fleming's left-hand rule, the autofocus (AF) movable unit can be moved in a first direction by the electromagnetic force caused by the interaction between the first coil 120 and the magnet 130. The movement of the AF movable unit in the first direction can be controlled by controlling the drive signal applied to the first coil 120 to adjust the strength and / or direction of the electromagnetic force. Thus, the autofocus function can be performed.

[0104] The movable AF unit may include a bobbin 110 elastically supported by an upper elastic member 150 and a lower elastic member 160, and components mounted in the bobbin 110 to move together with the bobbin 110. For example, the movable AF unit may include the bobbin 110, a first coil 120, and a lens (not shown) mounted in the bobbin 110.

[0105] The first coil 120 can be wound around the outer peripheral surface of the spool 110 to rotate clockwise or counterclockwise around the optical axis OA. In another embodiment, the first coil 120 can be implemented in the form of a coil loop wound clockwise or counterclockwise around an axis orthogonal to the optical axis OA, and the number of coil loops can be the same as the number of magnets 130, but is not limited thereto.

[0106] The first coil 120 may be electrically connected to at least one of the upper elastic member 150 or the lower elastic member 160 to receive a drive signal.

[0107] Next, the housing 140 will be described.

[0108] The housing 140 can support the magnet 130 and the sensing coil 170, and house the spool 110 in the housing 140 such that the spool 110 can move in a first direction by the electromagnetic force caused by the interaction between the first coil 120 and the magnet 130.

[0109] Figure 4 It shows Figure 1 The first exploded perspective view of the housing 140 and the magnet 130 shown, and Figure 5 It shows Figure 1 The second exploded perspective view of the housing 140 and the magnet 130 shown.

[0110] Reference Figure 4 and Figure 5The housing 140 may include a plurality of sides 141 and 142, which may be integrally hollow columnar in shape to form a hollow region therein. For example, the housing 140 may include a plurality of sides 141 and 142, each side 141 and 142 forming a polygonal (e.g., rectangular or octagonal) or circular hollow region therein.

[0111] The housing 140 may include an upper surface 401 and sides. The sides of the housing 140 may include a plurality of sides 141 and 142, and the upper surface of the sides may define the upper surface 401 of the housing 140.

[0112] For example, housing 140 may include a first side 141 spaced apart from each other and a second side 142 spaced apart from each other.

[0113] For example, the length of each first side 141 of the housing 140 may be greater than the length of each second side 142. For example, the first side 141 of the housing 140 may correspond to the side of the housing 140, and the second side 142 of the housing 140 may correspond to the corner of the housing 140.

[0114] The magnet 130 can be set or mounted on the first side 141 of the housing 140.

[0115] Each second side 142 of the housing 140 may be located between two adjacent first sides and connect the first sides 141 to each other.

[0116] The support member 220 may be disposed on the second side 142 of the housing 140.

[0117] For example, the support member 220 may pass through the through holes 147 respectively provided in the second side portion 142 and may be coupled to the outer frame 152 of the upper elastic member 150. For example, the through holes 147 may be formed in the second side portion 142 of the housing 142 and on the upper surface of the housing 140 adjacent to the second side portion 142.

[0118] The first side 141 of the housing 140 can be interconnected with the second side 142 of the housing 140, and can include a plane of a certain depth. Each first side 141 of the housing 140 can have an area that is the same as or larger than the area of ​​the corresponding magnet 130.

[0119] The housing 140 may include a magnet mounting portion 141a for accommodating a magnet 130 and a sensing coil mounting groove 141b for winding or accommodating a sensing coil 170.

[0120] The magnet mounting portion 141a may be disposed at the lower inner end of at least one first side portion 141 of the housing 140. For example, the magnet mounting portion 141a may be disposed at the lower inner end of each first side portion 141, and each magnet 130 may be inserted into and fixed to the corresponding magnet mounting portion in the magnet mounting portion 141a.

[0121] The magnet mounting portion 141a of the housing 140 can be formed as a groove corresponding to the size of the magnet 130. An opening can be formed in the bottom surface of the magnet mounting portion 141a of the housing 140 facing the second coil 240, and the bottom surface of the magnet 130 fixed to the magnet mounting portion 141a can face the second coil 230.

[0122] The sensing coil mounting groove 141b in the housing 140 can be formed in such a way that it is recessed from the outer surface of at least one of the first side portion 141 or the second side portion 142 of the housing 140, and can be formed from one end of the first side portion 141 and / or the second side portion 142 to the other end. For example, the sensing coil mounting groove 141b in the housing 140 can be provided in the upper end of the outer surface of the first side portion 141 and the second side portion 142.

[0123] For example, the sensing coil mounting groove 141b in the housing 140 may be spaced apart from the upper surface 401 of the housing 140, and may be disposed in the upper end of the outer surface of the first side 141 and the second side 142, but is not limited thereto.

[0124] The depth of the sensing coil mounting groove 141b can be greater than or equal to the thickness of the sensing coil 170 wound therein. For example, the sensing coil 170 disposed in the sensing coil mounting groove 141b may not protrude from the outer surface of the first and second sides of the housing 140. This is to prevent the sensing coil 170 disposed in the sensing coil mounting groove 141b from separating outward from the sensing coil mounting groove 141b.

[0125] The sensing coil mounting groove 141b can be disposed above the magnet mounting portion 141a of the magnet 130. For example, the sensing coil mounting groove 141b may not overlap with the magnet mounting portion 141a in a direction orthogonal to the optical axis OA, but it is not limited thereto.

[0126] The first side portion 141 of the housing 140 can be configured to be parallel to the side surface of the cover member 300. Furthermore, the area of ​​the first side portion 141 of the housing 140 can be larger than the area of ​​the second side portion 142.

[0127] The second side 142 of the housing 140 may have a through hole 147 therein, the through hole 147 defining a path through which the support member 220 passes. For example, the housing 140 may include a through hole 147 formed from the top of the second side 142. The number of through holes 147 may be the same as the number of support members.

[0128] To prevent the sensing coil 170 disposed in the sensing coil mounting groove 141b from separating from the housing 140, the housing 140 may include a protrusion 144 that protrudes from the upper surface 401 in a first direction. The protrusion 144 may be disposed on the sensing coil mounting groove 141b and may prevent the sensing coil 170, which is wound around the upper end of the side of the housing 140, from separating outward from the side of the housing 140.

[0129] For example, the protrusion 144 of the housing 140 may include: first protrusions 144a1 to 144a4, which are disposed on the upper end or upper surface of the first side portion 141 of the housing 140; and second protrusions 144b1 to 144b4, which are disposed on the upper end or upper surface of the second side portion 142.

[0130] The first protrusions 144a1 to 144a4 may be spaced apart from each other, and the second protrusions 144b1 to 144b4 may be spaced apart from each other. In addition, the first protrusions 144a1 to 144a4 and the second protrusions 144b1 to 144b4 may be spaced apart from each other.

[0131] For example, each of the first protrusions 144a1 to 144a4 may be configured to be aligned with the center of the upper surface of the corresponding first side 141, and each of the second protrusions 144b1 to 144b4 may be configured to be aligned with the center of the upper surface of the corresponding second side 142.

[0132] For example, the outer peripheral surfaces of each of the first protrusions 144a1 to 144a4 may be linear or linear in the longitudinal direction, and the outer peripheral surfaces of each of the second protrusions 144b1 to 144b4 may have a curved or bent shape in the longitudinal direction.

[0133] For example, the sensing coil mounting groove 141b may be spaced apart from the lower ends of the first protrusions 144a1 to 144a4 and the lower ends of the second protrusions 144b1 to 144b4, but is not limited thereto.

[0134] In another embodiment, the sensing coil mounting groove 141b can contact the lower ends of the first protrusions 144a1 to 144a4 and the lower ends of the second protrusions 144b1 to 144b4.

[0135] Stops 412a and 412b can be provided on the upper surface of the protrusion 144 of the housing 140 to prevent contact with... Figure 1 The inner surface of the cover member 300 shown is directly impacted.

[0136] For example, the housing 140 may include: a first stop 412a that protrudes from the upper surface of each of the first protrusions 144a1 to 144a4 in a first direction; and a second stop 412b that protrudes from the upper surface of each of the second protrusions 144b1 to 144b4 in a first direction.

[0137] For example, the first stop 412a can be configured to be aligned with the center of the corresponding first protrusion and can be linear or linear in the longitudinal direction, and the second stop 412b can be configured to be aligned with the center of the corresponding second protrusion and can have a curved or bent shape in the longitudinal direction.

[0138] At least one recess may be provided in the upper surface of the housing 140 between the protrusions 144a1 to 144a4 and the protrusions 144b1 to 144b4.

[0139] For example, the upper surfaces of the sides 141 and 142 of the housing 140 may include a first section S1 and a second section S2.

[0140] The protrusion 144 of the housing 140 may correspond to the first section S1 of the upper surface 401 of the housing 140, and the protrusion 144 may expose the second section S2 of the remaining part of the upper surface 401 of the housing 140 other than the first section S1.

[0141] Additionally, the recess in the housing 140 may correspond to the second section S2 of the upper surface 401 of the housing 140, and the second section S2 of the upper surface 401 of the housing 140 may be an open or exposed outer surface and / or inner surface of the side (e.g., 141) of the housing 140.

[0142] For example, the first section S1 of the housing 140 may have a structure that protrudes relative to the second section S2, and the second section S2 may have a structure that is recessed relative to the first section S1. Then, the second section S2 may have a structure that is open to the outer and / or inner surfaces of the respective sides 141 and 142 of the housing 140.

[0143] The sensing coil mounting groove 141b may include a first groove 144-1 disposed in the corresponding first side 141 and a second groove 144-2 disposed in the corresponding second side 142.

[0144] Assuming that, based on the through hole 147, the side of the housing 140 facing the hollow region is referred to as the "inner side" and the opposite side is referred to as the "outer side", then the second groove 144-2 of the sensing coil mounting groove 141b can be located outside the through hole 147 through which the support member 220 passes.

[0145] For example, compared to the through hole 147, the second groove 144-2 of the sensing coil mounting groove 141b can be located further away from the optical axis OA or through the center of the hollow region of the housing 140 and parallel to the optical axis OA, forming a virtual straight line.

[0146] For example, the first distance between the virtual straight line passing through the center of the hollow region of the housing 140 and parallel to the optical axis OA and the second groove 144-2 of the sensing coil mounting groove 141b can be greater than the second distance between the through hole 147 and the virtual straight line passing through the center of the hollow region of the housing 140 and parallel to the optical axis OA.

[0147] A portion of the second side 142 of the housing 140 may be disposed between the second groove 144-2 and the through hole 147 so that the support member 220 and the sensing coil 170 can be spaced apart from each other.

[0148] The recess or groove 402 may be provided in the side of the second groove 144-2 provided in the corresponding second side 142.

[0149] The housing 140 may include at least one upper support protrusion 143 disposed at the upper end or upper surface of the housing 140 for coupling to the outer frame 152 of the upper elastic member 150.

[0150] The upper support protrusion 143 of the housing 140 may be formed on the upper surface of at least one of the first side portion 141 or the second side portion 142 of the housing 140.

[0151] For example, the upper support protrusion 143 may be provided on the second region S2 of the upper surface 401 of the housing 140, located between the first protrusions 144a1 to 144a4 and the second protrusions 144b1 to 144b4.

[0152] In addition, the housing 140 may include a lower support protrusion 145 disposed on the lower surface of the housing 140 for coupling and securing to the outer frame 162 of the lower elastic member 160.

[0153] To define the path through which the support member 220 passes and to ensure that the space is filled with gel-type silicone to act as a damper, the housing 140 may include a groove 142a formed in the second side 142. That is, the groove 142a in the housing 140 may be filled with damping silicone resin.

[0154] To prevent the housing 140 from colliding with the cover member 300 when the housing 140 moves along the second direction and / or the third direction, the housing 140 may include at least one stop (not shown) that protrudes from the outer surface of each of the first sides 141 along the second direction or the third direction.

[0155] To prevent the bottom surface of housing 140 from colliding with base 210 and / or circuit board 250, which will be described below, housing 140 may also include a stop (not shown) protruding from its lower surface. By providing stops formed on the upper surface 401 and lower surface of housing 140, housing 140 can be spaced downwards from base 210 and upwards from cover member 300 to maintain the height of housing 140 in the optical axis OA direction without vertical interference. Therefore, housing 140 can be offset upwards in a second direction and a third direction, which are the longitudinal and transverse directions in a plane orthogonal to the optical axis OA.

[0156] Next, magnets 130 (130-1 to 130-4) will be described.

[0157] The magnet 130 can be disposed on the housing 140 such that at least a portion of the magnet overlaps with the first coil 120 in a direction orthogonal to the optical axis OA. For example, the magnet 130 can be inserted into or disposed in the mounting portion 141a of the housing 140.

[0158] The magnet 130 may be spaced apart from the sensing coil 170 mounted on the housing 140, and a portion of the housing 140 may be disposed between the sensing coil and the magnet 130.

[0159] The magnet 130 can be positioned below the sensing coil 170.

[0160] For example, in order to reduce interference between magnet 130 and sensing coil 170, magnet 130 and sensing coil 170 can be arranged so that they do not overlap each other in the direction of optical axis OA at their initial positions. However, the implementation is not limited to this, and in another implementation, they can be arranged to overlap each other.

[0161] For example, a sensing coil 170 may be disposed on the outer surface of the first side 141 and the second side 142 of the housing 140, and a magnet 130 may be disposed on the inner surface of the corresponding first side 141 of the housing 140.

[0162] In another embodiment, each of the magnets 130 may be disposed on the outer surface of the corresponding first side 141 of the housing 140, spaced apart from the sensing coil 170.

[0163] The magnet 130 may have a shape corresponding to the shape of the first side 141 of the housing 140, for example, a cuboid shape, but is not limited thereto.

[0164] The magnet 130 can be formed as a single unit and can be configured such that its surface facing the first coil 120 serves as the S pole and its opposing surface serves as the N pole. However, this disclosure is not limited thereto, and the polarity of the magnet can be reversed.

[0165] At least two magnets 130 may be disposed on the housing 140 and may be arranged facing each other. For example, magnets 130 may have a generally rectangular flat surface, or alternatively may have a triangular or rhomboid shape.

[0166] For example, magnet 130 can be disposed on two first sides facing each other in the first side 141 of housing 140.

[0167] Next, the upper elastic member 150, the lower elastic member 160, and the support member 200 will be described.

[0168] Upper elastic member 150 and lower elastic member 160 elastically support the bobbin 110. Upper elastic member 150 is connected to the upper part of bobbin 110 and the upper part of housing 140 to support the upper part of bobbin 110 and housing 140. Lower elastic member 160 is connected to the lower part of bobbin 110 and the lower part of housing 140 to support the lower part of bobbin 110 and housing 140.

[0169] At least a portion of the upper elastic member 150 may be disposed on the upper surface of the sides 141 and 142 of the housing 140, between the protrusions 144a1 to 144a4 and 144b1 to 144ab. For example, at least a portion of the upper elastic member 150 may be disposed on the upper surface of the first side 141 of the housing 140, between the first protrusions 144a1 to 144a4 and the second protrusions 144b1 to 144b4.

[0170] For example, a portion of the outer frame 152 of the upper elastic member 150 may be disposed on the upper surface of the first side portion 141 of the housing 140, between the first protrusion and the second protrusion.

[0171] A portion 901, in which the first coupling portion 510 and the frame connection portion 153 of the upper elastic member 150 are connected to each other, can be provided on the upper surface of the first side portion 141 of the housing 140 between the first protrusions 144a1 to 144a4 and the second protrusions 144b1 to 144b4.

[0172] Additionally, at least a portion of the upper elastic member 150 may be disposed in at least one recess in the upper surface of the housing 140. The at least one recess in the housing 140 may open to the outer surface and / or inner surface of the side portion of the housing 140, and at least a portion of the upper elastic member 150 disposed in the at least one recess may be exposed to the outer surface of the side portion of the housing 140.

[0173] Additionally, for example, at least one recess in the housing 140 may be provided in the same side of the housing 140 where the magnet 130 is provided, but this disclosure is not limited thereto. In another embodiment, at least one recess in the housing 140 may be provided in a side of the housing 140 different from the side where the magnet 130 is provided.

[0174] Additionally, at least one recess in the housing 140 may be configured to be adjacent to at least one side of the upper surface of the housing 140.

[0175] At least a portion of the outer frame of the upper elastic member 150 may be disposed in at least one recess in the housing 140. The sensing coil 170 may be spaced apart from the upper elastic member 150 disposed in the recess in the housing 140, and at least a portion of the outer frame of the upper elastic member 150 disposed in at least one recess may overlap with the sensing coil 170 in the optical axis direction.

[0176] For example, at least one recess in the housing 140 may include a bottom and a side surface, the sensing coil 170 may be disposed below the bottom of the recess in the housing 140, and at least a portion of the upper elastic member 150 may be configured to contact the bottom of the recess.

[0177] The upper support protrusion 143 may be disposed on the bottom of at least one recess in the housing 140 so as to be coupled to the outer frame of the upper elastic member 150.

[0178] The depth of the bottom of at least one recess in the housing 140 may be greater than or equal to the height of at least a portion of the upper elastic member 150 disposed on the bottom of the recess, in order to prevent the upper elastic member 150 from separating. That is, based on the bottom of the recess in the housing 140, the height of the upper end or upper surface of the upper elastic member 150 disposed in the recess may be less than or equal to the height of the upper end or upper surface of the protrusion of the housing 140.

[0179] The support member 220 can movably support the housing 140 relative to the base 210 in a direction orthogonal to the optical axis OA, and can electrically connect at least one of the upper elastic member 150 or the lower elastic member 160 to the circuit board 250. For example, the support member 220 can electrically connect the upper elastic member 150 to the circuit board 250.

[0180] Upper elastic member 150 is not limited to Figure 2 The upper elastic member 150 is shown, and regarding the following description... Figure 20 The description of the upper elastic member 1600 shown can be applied to the upper elastic member 150.

[0181] For example, refer to Figure 20 According to another embodiment, the upper elastic member may include an outer frame 1610 coupled to the upper part of the housing 140, an inner frame 1620 coupled to the upper part of the spool 110, and a frame connecting portion 1630 connecting the outer frame 1610 and the inner frame 1620 to each other.

[0182] The outer frame 1610 may include a first outer frame 1611, a second outer frame 1612, a third outer frame 1613, and a fourth outer frame 1614.

[0183] The first outer frame 1611 can be connected to the inner frame 1620 via the frame connection portion 1630, and the second outer frame 1612 can be spaced apart from the frame connection portion 1630 and the inner frame 1620 of the first outer frame 1611.

[0184] The first external coil 1611 and the third external coil 1613 can be electrically connected to the first coil 120, and the second external coil 1612 and the fourth external coil 1614 can be electrically connected to the sensing coil 170.

[0185] The first outer portion 1611, the second outer portion 1612, the third outer portion 1613, and the fourth outer portion 1614 may be located at the corner of the housing 140, for example, on the second side portion 142. For example, the first outer portion 1611, the second outer portion 1612, the third outer portion 1613, and the fourth outer portion 1614 may extend along the side surface of the corner portion of the housing 140.

[0186] The inner frame 1620 may include a first inner portion 1621 and a second inner portion 1622 that are coupled to the coil 110 and spaced apart from each other. The first inner portion 1621 may be electrically connected to one end of the first coil 120, and the second inner portion 1622 may be electrically connected to the other end of the first coil.

[0187] The inner frame 1620 may include a first inner coupling portion 6211 coupled to a first side of the spool 110, a second inner coupling portion 6212 coupled to a second side of the spool 110, and a third inner coupling portion 6213 coupled to a third side of the spool 110.

[0188] Additionally, the inner frame 1620 may also include a virtual portion 1625 connecting the first inner coupling portion 6211 and the second inner coupling portion 6212 to each other. Furthermore, the inner frame 1620 may also include a virtual portion 1625 connecting the second inner coupling portion 6212 and the third inner coupling portion 6212 to each other.

[0189] The frame connecting portion 1630 may include a first connecting portion 1631, a second connecting portion 1632, a third connecting portion 1633, and a fourth connecting portion 1634 spaced apart from each other.

[0190] The first outer part 1611 can be connected to the first inner part 1621 through the first connecting part 1631 and the second connecting part 1632, the third outer part 1613 can be connected to the second inner part 1622 through the third connecting part 1633 and the fourth connecting part 1634, and the fourth outer part 1614 can be spaced apart from the frame connecting part 1630 and the inner frame 1620.

[0191] The second outer 1612 and the fourth outer 1614 may not be coupled to the drum 110, but may be coupled only to the housing 140.

[0192] like Figure 18 As shown, the leads of the sensing coil 170 can be coupled to the outer frame 1610 via solder element 1912. Furthermore, as... Figure 19 As shown, the leads of the first coil 120 can be coupled to the inner frame 1620 via solder element 1222.

[0193] Figure 6 It shows Figure 1 An assembly perspective view of the upper elastic member 150, lower elastic member 160, base 210, support member 220, second coil 230 and circuit board 250 shown.

[0194] Reference Figure 6 The upper elastic member 150 can be divided into two or more pieces.

[0195] For example, the upper elastic member 150 may include a first upper elastic member 150-1, a second upper elastic member 150-2, a third upper elastic member 150-3, and a fourth upper elastic member 150-4 that are electrically isolated from and spaced apart from each other. For example, the separate first upper elastic member 150-1, second upper elastic member 150-2, third upper elastic member 150-3, and fourth upper elastic member 150-4 may be arranged symmetrically about the center point of the spool 110 or housing 140 in the xy plane. Here, "point symmetry" refers to the symmetry in which the two shapes overlap when rotated 180 degrees about a center point of rotation.

[0196] Any one of the first upper elastic member 150-1, the second upper elastic member 150-2, the third upper elastic member 150-3, and the fourth upper elastic member 150-4 can be electrically connected to a corresponding support member 220 among the support members 220. For example, each of the first upper elastic member 150-1, the second upper elastic member 150-2, the third upper elastic member 150-3, and the fourth upper elastic member 150-4 can be directly connected to a corresponding support member among the first support member 220-1, the second support member 220-2, the third support member 220-3, and the fourth support member 220-4.

[0197] Each of the first upper elastic member 150-1, the second upper elastic member 150-2, the third upper elastic member 150-3, and the fourth upper elastic member 150-4 may include an inner frame 151 connected to the spool 110, an outer frame 152 connected to the housing 140, and a frame connection portion 153 connecting the outer frame 152 and the inner frame 151 to each other.

[0198] For example, the inner frame 151 may be provided with a through hole 151a, and the upper support protrusion 113 of the spool 110 is coupled to the through hole 151a, and the outer frame 152 may be provided with a through hole 152a, and the upper support protrusion 143 of the housing 140 is coupled to the through hole 152a.

[0199] Two upper elastic members selected from the first upper elastic member 150-1 to the fourth upper elastic member 150-4 can be connected to both ends of the first coil 120. For example, the inner frames of the two upper elastic members selected from the first upper elastic member 150-1 to the fourth upper elastic member 150-4 can be electrically connected to both ends of the first coil 120.

[0200] Furthermore, two other upper elastic members selected from the first upper elastic member 150-1 to the fourth upper elastic member 150-4 can be connected to both ends of the sensing coil 170. For example, the outer frames of two upper elastic members selected from the first upper elastic member 150-1 to the fourth upper elastic member 150-4 can be electrically connected to both ends of the sensing coil 170.

[0201] For example, the front end portion of the sensing coil 170 can be directly joined to the outer frame of any one of the first upper elastic member 150-1 to the fourth upper elastic member 150-4 by welding, and the rear end portion of the sensing coil 170 can be directly joined to the outer frame of any other one of the first upper elastic member 150-1 to the fourth upper elastic member 150-4.

[0202] Additionally, the outer frame 152 of each of the first upper elastic member 150-1 to the fourth upper elastic member 150-4 may be connected to at least one of the support members 220-1 to 220-4. For example, each of the outer frames 152 of the first upper elastic member 150-1 to the fourth upper elastic member 150-4 may be connected to one end of a corresponding one of the support members 220-1 to 220-4.

[0203] The frame connection portion 153 of the upper elastic member 150 can be bent at least once to form a pattern with a predetermined shape. The upward and / or downward movement of the spool 110 in the first direction can be elastically supported by the positional change and slight deformation of the frame connection portion 153 of the upper elastic member 150.

[0204] The outer frame 152 of each of the first upper elastic member 150-1 to the fourth upper elastic member 150-4 may include a first coupling portion 510 coupled to the housing 140, a second coupling portion 520 coupled to the corresponding support member 220, and a connecting portion 530 connecting the first coupling portion 510 and the second coupling portion 520 to each other.

[0205] For example, one end of each support member 220-1 to 220-4 can be directly coupled to the second coupling portion 520 of the outer frame 152 of the upper elastic member 150 by welding or using a conductive adhesive member (e.g., conductive epoxy resin).

[0206] The first coupling portion 510 of the upper elastic member 150 is connected to the frame connection portion 153 at one end and has a through hole 152a, to which the upper support protrusion 143 of the housing 140 is coupled.

[0207] The connecting portion 530 of the outer frame 152 of each of the first upper elastic member 150-1 to the fourth upper elastic member 150-4 can be straightened or bent at least once, and the width of the connecting portion 530 can be less than the width of the frame connecting portion 153 of the upper elastic member 150.

[0208] Since the width of the connecting portion 530 is smaller than the width of the frame connecting portion 153 of the upper elastic member 150, the connecting portion 530 can be easily moved in the first direction, which can distribute the stress applied to the upper elastic member 150 and the stress applied to the support member 220.

[0209] For example, the second coupling portion 520 of the upper elastic member 150 may include a through hole through which the support member 220 passes, but is not limited thereto.

[0210] The lower elastic member 160 may include an inner frame 161 coupled to the lower support protrusion of the spool 110, an outer frame 162 coupled to the lower support protrusion of the housing 140, and a frame connection portion 163 connecting the inner frame 161 and the outer frame to each other.

[0211] exist Figure 6 In the middle, the lower elastic member 160 is not divided, but in another embodiment it can be divided into two or more pieces.

[0212] The sensing coil 170 will be described next.

[0213] The sensing coil 170 is disposed on the side of the housing 140, for example, on sides 141 and 142 of the housing 140. For example, the sensing coil 170 can be directly wound in the sensing coil mounting groove 141b disposed in the first side 141 and the second side 142 of the housing 140, so as to rotate clockwise or counterclockwise around the optical axis OA. For example, the sensing coil 170 can be directly wound on the housing 140 in a ring shape.

[0214] When the sensing coil is implemented as a coil block and attached to the upper end of the housing 140, manual operation is required to position and attach the sensing coil. In this case, it is not easy to implement the sensing coil in block form to match the shape of the upper surface of the housing, and since the sensing coil is attached to the housing by manual operation, the reliability of the adhesion between the sensing coil and the housing may be deteriorated. In addition, since the sensing coil is positioned adjacent to the upper elastic member at the upper end of the housing, the installation of the upper elastic member may be restricted, and the joining and welding operations with the upper elastic member are not easy.

[0215] On the other hand, in the embodiment, since the sensing coil 170 is directly wound in the sensing coil mounting groove 141b provided in the first side 141 and the second side 142 of the housing 140, there is no need for manual operation to place and engage the sensing coil 170 to the upper end of the housing 140. This can prevent the engagement reliability between the sensing coil 170 and the housing 140 and between the sensing coil 170 and the upper elastic member 150 from deteriorating.

[0216] In addition, since the sensing coil 170 is located below the upper elastic member 150, there is no space restriction when the upper elastic member 150 is installed on the upper end of the housing 140.

[0217] Since each of the front and rear portions of the sensing coil 170 is configured to contact the area of ​​the first sidewall 141 or the second sidewall 142 of the housing 140 and is joined to the area of ​​the outer frame 152 of the upper elastic member 150 by welding, this embodiment ensures that welding is easy to achieve.

[0218] The drive signal applied to the first coil 120 can be an alternating current (AC) signal (e.g., alternating current). For example, the AC signal can be a sinusoidal signal or a pulse signal (e.g., a pulse width modulation (PWM) signal). Alternatively, in another embodiment, the drive signal applied to the first coil 120 can include both an AC signal (e.g., alternating current) and a direct current (DC) signal (e.g., direct current). Applying an AC signal to the first coil 120 is used to generate an electromotive force or induced voltage in the sensing coil 170 through interactive induction.

[0219] The first coil 120 can move together with the bobbin 110 in a first direction in response to a drive signal via an electromagnetic force caused by the electromagnetic interaction between the current flowing in the first coil 120 and the magnet 130.

[0220] As the first coil 120 moves along the first direction, the distance between the first coil 120 and the sensing coil 170 changes. As the distance changes, an induced voltage can be generated in the sensing coil 170. For example, as the distance decreases, the induced voltage generated in the sensing coil 170 increases. Conversely, as the distance increases, the induced voltage generated in the sensing coil 170 decreases.

[0221] The displacement of the first coil 120 and the drum 110 can be detected based on the voltage induced in the sensing coil 170, and the displacement of the drum 110 or the feedback control of the drive signal can be realized based on the detected displacement.

[0222] The sensing coil 170 can be disposed below the upper elastic member 150 and above the magnet 130. The upper elastic member 150 is disposed on the upper surface of the housing 140, and the magnet 130 is disposed on the housing 140.

[0223] At least a portion of the sensing coil 170 disposed on the housing 140 may overlap with the protrusion 144 of the housing 140 in a first direction, but this disclosure is not limited thereto. In another embodiment, at least a portion of the sensing coil 170 may not overlap with the protrusion 144 of the housing 140.

[0224] Next, the support member 220 will be described.

[0225] Multiple support members 220 can be provided, and the multiple support members 220-1 to 220-4 can be configured to correspond to the second side 142 of the housing 140. For example, each of the multiple support members 220-1 to 220-4 can be configured to be adjacent to one of the corresponding four second side 142, and one end of the support member 220 can be engaged to the outer frame 152 of the upper elastic member 150 provided on the corresponding second side. Alternatively, in another embodiment, the support member 220 can be provided on the first side 141 of the housing 140 in the form of a leaf spring.

[0226] Multiple support members 220-1 to 220-4 may define a path through which a drive signal is transmitted from circuit board 250 to first coil 120, and the multiple support members 220-1 to 220-4 may also define a path through which an induced voltage output from sensing coil 170 is transmitted to circuit board 250.

[0227] Multiple support members 220-1 to 220-4 can be implemented by members capable of providing elastic support force (e.g., leaf springs, coil springs, suspension wires, etc.). Alternatively, in another embodiment, the support member 220 can be integrally formed with the upper elastic member.

[0228] Multiple support members 220-1 to 220-4 may be spaced apart from the housing 140 and may be directly connected to the connection portion 530 of the outer frame 153 of the upper elastic member 150, rather than being fixed to the housing 140.

[0229] The connecting portion 530 of the outer frame 153 of the upper elastic member 150 is spaced apart from the housing 140, so it can be easily moved along the first direction.

[0230] Since the support members 220-1 to 220-4 according to the embodiment are directly connected to the connecting portion 530, which can be easily moved in the first direction, the support members can move more easily in the first direction than ordinary support members fixed to the housing 140, which can improve the accuracy of hand tremor compensation. In particular, stress caused by drops and other types of impacts can be dispersed, and deformation and breakage of the support members 220-1 to 220-4 caused thereby can be suppressed.

[0231] The first upper elastic member 150-1 to the fourth upper elastic member 150-4 can be electrically connected to the circuit board 250 through the support members 220-1 to 220-4.

[0232] For example, the two ends of the first coil 120 can be connected to the inner frame 151 of the first upper elastic member 150-1 and the second upper elastic member 150-2, and can be electrically connected to the circuit board 250 through the first upper elastic member 150-1, the second upper elastic member 150-2, and the support members 220-2 and 220-3.

[0233] In addition, the two ends of the sensing coil 170 can be connected to the inner frame 151 of the third upper elastic member 150-3 and the fourth upper elastic member 150-4, and can be electrically connected to the circuit board 250 through the third upper elastic member 150-3, the fourth upper elastic member 150-4 and the support members 220-1 to 220-4.

[0234] Support members 220-1 to 220-4 may be located within the annular sensing coil 170.

[0235] Next, the base 210, the circuit board 250, and the second coil 230 will be described.

[0236] The base 210 may include a hollow region corresponding to the hollow region of the spool 110 and / or the hollow region of the housing 140, and the base 210 may have a shape that matches or corresponds to the shape of the cover member 300, for example, a rectangular shape.

[0237] Figure 7 It shows Figure 1 An exploded perspective view of the base 210, the second coil 230, and the circuit board 250 shown.

[0238] Reference Figure 7 The base 210 may include a step 211 to which an adhesive may be applied when engaging and securing the cover member 300. Here, the step 211 may guide the cover member 300 coupled to its upper side and may be coupled to the end of the cover member 300 in a surface contact manner.

[0239] A support portion 255 can be formed on the surface of the base 210 facing the circuit board 250 on which the terminals 251 are formed, thereby having dimensions corresponding to the dimensions of the base surface. The support portion 255 of the base 210 can be formed without the step portion 211 so as to have a specific cross section from the outer surface of the base 210 and can be used to support the terminal surface 253 of the circuit board 250.

[0240] The edge of the base 210 may have a groove 212. When the edge of the cover member 300 has a protruding shape, the protrusion of the cover member 300 may be fastened to the groove 212 in the base 210.

[0241] Additionally, the upper surface of the base 210 may be provided with mounting grooves 215-1 and 215-2, and the OIS position sensor 240 may be disposed in the mounting grooves 215-1 and 215-2. According to an embodiment, the base 210 may be provided with two mounting grooves 215-1 and 215-2, and the OIS position sensor 240 may be disposed in the mounting grooves 215-1 and 215-2 of the base 210 to sense the degree of movement of the housing 140 in the second and third directions. For this purpose, the virtual line connecting the centers of the mounting grooves 215-1 and 215-2 of the base 210 and the center of the base 210 may intersect each other. For example, the angle formed by the virtual line connecting the centers of the mounting grooves 215-1 and 215-2 of the base 210 and the center of the base 210 may be 90°, but is not limited to this.

[0242] The second coil 230 can be disposed on the upper side of the circuit board 250, and the OIS position sensor 240 can be disposed on the lower side of the circuit board 250.

[0243] The OIS position sensor 240 can sense the displacement of the housing 140 relative to the base 210 in a direction orthogonal to the optical axis OA (e.g., the Z-axis) (e.g., the X-axis or Y-axis). For example, the OIS position sensor 240 can sense the change in the magnetic force of the magnet 130 caused by the movement of the housing 140, and can output a signal based on the sensing result.

[0244] The OIS position sensor 240 may include a first OIS position sensor 240a and a second OIS position sensor 240b, which are arranged orthogonally to each other to sense the displacement of the housing 140 in a direction orthogonal to the optical axis OA.

[0245] The circuit board 250 can be disposed on the upper surface of the base 210 and can have a hollow region corresponding to the hollow region of the spool 110, the hollow region of the housing 140, and / or the hollow region of the base 210. The shape of the outer peripheral surface of the circuit board 250 can have a shape that matches or corresponds to the shape of the upper surface of the base 210, for example, a rectangular shape.

[0246] The circuit board 250 may have at least one terminal surface 253 on which a plurality of terminals 251 or pins are formed, which bend from the upper surface and receive electrical signals from the outside.

[0247] exist Figure 7In this embodiment, the second coil 230 is disposed in a circuit component 231 separate from the circuit board 250, but this disclosure is not limited thereto. In another embodiment, the second coil 230 may be implemented in the form of a ring coil block, in the form of an FP coil, or in the form of a circuit pattern formed on the circuit board 250.

[0248] A through-hole 230a can be formed in the circuit component 231 in which the second coil 230 is formed. The support component 220 can be electrically connected to the circuit board 250 through the through-hole 230a.

[0249] The second coil 230 is disposed on the circuit board 250 facing the magnet 130 disposed in the housing 140.

[0250] A total of four second coils 230 may be provided on the four sides of the circuit board 250, but this disclosure is not limited thereto. Only two second coils may be provided in the second direction and the third direction respectively, or more than four second coils may be provided.

[0251] Shake compensation can be performed when the housing 140 moves upward in a second direction and / or a third direction by the interaction of the magnets 130 and the second coil 230, which are arranged to face each other.

[0252] OIS position sensors 240a and 240b can be provided as Hall sensors, or any other sensor capable of sensing the strength of a magnetic field can be used. For example, OIS position sensors 240a and 240b can be implemented as a driver that includes a Hall sensor, or they can be implemented simply as position detection sensors themselves, such as Hall sensors.

[0253] OIS position sensors 240a and 240b can sense the displacement of housing 140 and can use the sensed displacement to perform OIS feedback operations.

[0254] Multiple terminals 251 can be disposed on the terminal surface 253 of the circuit board 250.

[0255] For example, a plurality of terminals 251 disposed on the terminal surface 253 of the circuit board 250 can receive external power to supply power to the first coil 120, the second coil 230 and the OIS position sensor 240, can receive the induced voltage output from the sensing coil 170 to output the voltage to the outside, and can receive the output signal from the OIS position sensor 240 to output the signal to the outside.

[0256] According to the embodiment, the circuit board 250 may be formed by an FPCB, but is not limited thereto, and the terminals of the circuit board 250 may be formed directly on the surface of the base 210 using a surface electrode method or the like.

[0257] The circuit board 250 may include through holes 250a1 and 250a2 through which the support member 220 can pass. The support member 220 may be electrically connected to a corresponding circuit pattern that may be disposed on the lower surface of the circuit board 250 through the through holes 250a1 and 250a2 in the circuit board 250 by means of soldering or the like.

[0258] In another embodiment, the circuit board 250 may not include through holes 250a1 and 250a2, and the support member 220 may be electrically connected to a circuit pattern or pad formed on the upper surface of the circuit board 250 by soldering or the like.

[0259] The circuit board 250 may also include a through hole 250b, with an upper support protrusion 217 of the base 210 coupled to the through hole 250b.

[0260] Figure 8 It shows Figure 2 The side perspective view of the lens driving device shown is shown. Figure 9 It shows along Figure 2 The lens drive device shown is a cross-sectional view taken along line I-I'. Figure 10 It shows along Figure 2 The lens drive device shown is a cross-sectional view taken along line II-II'.

[0261] Reference Figures 8 to 10 The sensing coil 170 is directly wound in the sensing coil mounting groove 141b provided in the first side surface 141 and the second side surface 142 of the housing 140.

[0262] In the initial position, the sensing coil 170 may not overlap with the magnet 130 in a direction orthogonal to the first direction. This is to reduce interference between the magnet 130 and the sensing coil 170.

[0263] The initial position can be the initial position of the AF movable unit when no power is applied to the first coil 120, or it can be the position where the AF movable unit is positioned such that the upper elastic member 150 and the lower elastic member 160 are elastically deformed only by the weight of the AF movable unit. The AF movable unit may include a bobbin 110 and constituent elements mounted in the bobbin 110.

[0264] Furthermore, at the initial position, the sensing coil 170 can be spaced a predetermined distance from the first coil 120 in the first direction, and can avoid overlapping with the first coil 120 in a direction orthogonal to the first direction. Maintaining the predetermined distance between the first coil and the sensing coil 170 in the first direction ensures the linearity of the induced voltage in the sensing coil 170 induced by the current of the first coil 120.

[0265] In the initial position, the sensing coil 170 may overlap with the magnet 130 in the first direction, but this disclosure is not limited thereto. In another embodiment, the two may not overlap in the first direction.

[0266] The sensing coil 170 can be directly wound around the side of the housing 140, such that at least a portion of it is located outside the support member 220. For example, the outer side of the support member 220 can be opposite to the center of the hollow region of the housing 140.

[0267] The support member 220 can be located between the first coil 120 and the sensing coil 170 in a direction orthogonal to the optical axis OA.

[0268] The sensing coil 170 may include a first portion 170-1 disposed on the outer surface of the first side portion 141 (see...) Figure 8 ), and a second portion 170-2 disposed on the outer surface of the second side portion 142 (see Figure 8 ).

[0269] For example, each first portion 170-1 of the sensing coil 170 may be linear, and each second portion 170-2 may be curved.

[0270] The second portion 170-2 of the sensing coil 170 may be located outside the support member 220. For example, each second portion 170-2 of the sensing coil 170 may be located outside the corresponding support member among the support members 220-1 to 220-4.

[0271] The distance from the center of housing 140 to each of the support members 220-1 to 220-4 is less than the distance from the center of housing 140 to each of the second portions 170-2 of sensing coil 170. For example, the distance from the center of housing 140 to any one of the support members (e.g., 220-1) may be less than the distance from the center of housing to the second portion 170-2 of sensing coil 170 corresponding to the support member (e.g., 220-1).

[0272] The sensing coil 170 does not overlap with the frame connection portion 153 of each of the first upper elastic members 150-1 to the fourth upper elastic members 150-4 in the first direction. Therefore, assuming the number of turns is the same, the length of the sensing coil 170 can be increased.

[0273] At least a portion of the outer frame 152 of the upper elastic member 150 may be disposed on the second section S2 of the upper surface 401 of the housing 140 exposed through the protrusion 144. Thus, the sensing coil 170 may overlap with the outer frame 152 of each of the first upper elastic members 150-1 to the fourth upper elastic members 150-4 in the first direction.

[0274] For example, at least a portion of the first coupling portion 510 of the outer frame 152 of each of the first upper elastic member 150-1 to the fourth upper elastic member 150-4 may overlap with the sensing coil 170 in the first direction.

[0275] For example, the portion 901 where the first coupling portion 510 and the frame connection portion 153 of the first upper elastic member 150-1 to the fourth upper elastic member 150-4 are connected to each other can overlap with the sensing coil 170 in the first direction.

[0276] Since the upper elastic member 150 can be disposed on the upper surface of the housing 140 such that its outer frame 152 overlaps with the sensing coil 170 in the first direction, there is no space restriction when the upper elastic member 150 is disposed on the housing, and the upper elastic member 150 can be disposed with increased degrees of freedom.

[0277] Since the sensing coil 170 is wound directly around the side of the housing 140, such that its second portion 170-2 is located outside the support members 220-1 to 220-4, according to the embodiment, the sensing coil 170 can be wound on the upper end of the outer surface of the first side 141 and the second side 142 of the housing 140, and the length of the sensing coil 170 wound around the housing 140 once can be increased. To achieve a sensing coil 170 with a predetermined resistance value, the number of turns in the housing 140 can be reduced as the length of the sensing coil 170 wound once increases. Then, as the number of turns of the sensing coil 170 decreases, the area of ​​the housing 140 required for the sensing coil 170 can be reduced, and the area for mounting the magnet 130 can be increased, which allows for an increase in the size of the magnet that can be mounted in the housing 140.

[0278] For example, the resistance of the sensing coil may be affected by temperature changes, and the sensing current may change due to these changes in resistance. Since the effect of this temperature-induced change in sensing current can cause AF drive malfunctions, temperature compensation is required. This temperature compensation can be easily performed by making the resistance of the sensing coil equal to or greater than a predetermined resistance value (e.g., 30Ω). This implementation allows for a sufficient resistance value to facilitate temperature compensation using a small number of turns.

[0279] Therefore, by ensuring space in the housing 140 where a magnet 130 of a larger size can be placed, this embodiment can increase the electromagnetic force generated by the interaction with the magnet 130.

[0280] Figure 11 It is shown Figure 8 A top view of the arrangement of the sensing coil 170 shown.

[0281] Reference Figure 11 Since the sensing coil 170 is wound around the housing 140, the bent portion 302 of the sensing coil 170 is located outside the support member 220-1. Therefore, compared with the case where the bent portion of the sensing coil 170 is located inside the support member 220-1, the length of one turn of the sensing coil 170 can be increased.

[0282] As described above, in the embodiment, since the sensing coil 170 is directly wound on the outer surfaces of the first side 141 and the second side 142 of the housing 140, the reliability of the engagement between the sensing coil 170 and the housing 140 or between the sensing coil 170 and the upper elastic member 150 can be prevented from deteriorating.

[0283] Furthermore, since the sensing coil 170 is disposed below and spaced apart from the upper elastic member 150, in this embodiment, the upper elastic member 150 is disposed at the upper end of the housing 140 without any space restriction.

[0284] In addition, since the sensing coil 170 is disposed outside the support member 220, the length of the outermost periphery of the sensing coil 170 can be maximized to achieve a sensing coil 170 with a predetermined resistance using a small number of turns, and the size of the magnet 130 that can be disposed on the housing 140 can be increased to increase the electromagnetic force for AF or OIS drive.

[0285] Figure 12 It shows the result of Figure 8 The top view of part II, indicated by the dashed line. Figure 13 It shows the result of Figure 8 The dashed line indicates the side perspective view of part II.

[0286] To ensure the linearity of the induced voltage in the sensing coil 170 induced by the current through the first coil 120, it may be necessary to set the distance between the first coil 120 and the sensing coil 170 in the first direction to be equal to or greater than a predetermined distance.

[0287] According to the embodiment, the sensing coil 170 is disposed on the upper end of the sides 141 and 142 of the housing 140 adjacent to the upper surface 401 of the housing 140, such that the distance between the first coil 120 and the sensing coil 170 can be equal to or greater than a predetermined distance in the first direction.

[0288] When the sensing coil 170 is disposed on the upper ends of the sides 141 and 142 of the housing 140, the sensing coil 170 can be separated upward from the housing 140. The protrusion 144 of the housing 140 in this embodiment can be used to prevent the sensing coil 170 disposed on the upper ends of the sides of the housing 140 from separating upward.

[0289] Unlike this embodiment, when the protrusion 144 of the housing 140 is provided on the front edge of the upper surface of the housing 140 corresponding to or aligned with the sensing coil 140 provided on the housing 140, the space for providing the upper elastic member 150 on the upper surface of the elastic member 140 can be limited. Therefore, this embodiment can overcome the space limitations related to the installation of the upper elastic member 150 by providing the protrusion 144 so that the second section S2 of the upper surface 401 of the housing 140 can be exposed and the outer frame 152 of the upper elastic member 150 can be provided on the second section S2 of the upper surface 401 of the housing 140.

[0290] A portion 501 on the side of the housing 140 may be disposed between the upper elastic member 150 and the sensing coil 170 to prevent interference or contact between the upper elastic member 150 and the sensing coil 170.

[0291] Here, the distance d1 between the lower surface of the upper elastic member 150 and the upper surface of the sensing coil 170 can be in the range of 0.05 mm to 1 mm. When the distance d1 is less than 0.05 mm, interference or contact may occur between the upper elastic member 150 and the sensing coil 170. For example, the distance d1 between the lower surface of the upper elastic member 150 and the upper surface of the sensing coil 170 can be in the range of 0.05 mm to 0.1 mm. When the distance d1 exceeds 1 mm, the distance between the first coil 120 and the sensing coil 170 in the first direction may not be sufficiently ensured, making it impossible to ensure the linearity of the induced voltage of the sensing coil 170.

Figure 15 yes Figure 14 The exploded perspective view of the lens driving device shown is as follows.

[0293] In the following text, the direction toward the center of the lens drive device will be referred to as the "inner side", and the direction away from the center of the lens drive device will be referred to as the "outer side".

[0294] In the following text, any one of the AF coil unit 1220, the driving magnet unit 1320, and the OIS coil unit 1420 may be referred to as the "first driving unit," another may be referred to as the "second driving unit," and the remaining one may be referred to as the "third driving unit." The embodiment will be described assuming that the AF coil unit 1220 is located on the bobbin 1210, the driving magnet unit 1320 is located on the housing 1310, and the OIS coil unit 1420 is located on the base 1500; however, the AF coil unit 1220, the driving magnet unit 1320, and the OIS coil unit 1420 can be arranged interchangeably. Furthermore, at least one of the AF coil unit 1220 and the OIS coil unit 1420 can be replaced by an additional magnet unit. That is, the first to third driving units can be arranged in any other configuration, as long as they can selectively interact electromagnetically with each other.

[0295] In the following text, any one of the AF coil unit 1220, OIS coil unit 1420 and sensing coil unit 1910 may be referred to as the "first coil unit", another may be referred to as the "second coil unit" and the remainder may be referred to as the "third coil unit".

[0296] In the following text, any one of the upper elastic member 1600, the lower elastic member 1700, and the lateral support member 1800 may be referred to as the "first support member", another may be referred to as the "second support member", and yet another may be referred to as the "third support member".

[0298] The cover member 1100 can accommodate the housing 1310 and the spool 1210 within its internal space. The cover member 1100 can be coupled to the base 1500. The cover member 1100 can form the appearance of a lens drive device. The cover member 1100 can be in the form of a hexahedron with an open bottom. However, this disclosure is not limited thereto.

[0299] For example, the cover member 1100 can be formed of a metallic material. More specifically, the cover member 1100 can be formed of a metal plate. In this case, the cover member 1100 can block electromagnetic interference (EMI). Due to this feature of the cover member 1100, the cover member 1100 can be referred to as an "EMI shield". The cover member 1100 can prevent electromagnetic waves generated outside the lens driving device from entering the cover member 1100. Furthermore, the cover member 1100 can prevent electromagnetic waves generated inside the cover member 1100 from being emitted to the outside of the cover member 1100. However, the material of the cover member 1100 is not limited to this.

The cover member 1100 may be mounted on the base 1500 such that the inner surface of the cover member is in close contact with a portion or all of the side surface of the base 1500. A first mover 1200, a second mover 1300, a stator 1400, and support members 1600, 1700, and 1800 may be located within the internal space defined by the cover member 1100 and the base 1500. With this structure, the cover member 1100 can protect the internal components from external impacts and prevent the ingress of external contaminants. However, this disclosure is not limited thereto, and the lower end of the side plate 1120 of the cover member 1100 can be directly coupled to a printed circuit board located below the base 1500.

[0301] The cover member 1100 may include an opening 1130 formed in the upper plate 1110 to expose the lens module. The opening 1130 may be configured to correspond to the shape of the lens module. The size of the opening 1130 may be larger than the diameter of the lens module, allowing the lens module to be assembled through the opening 1130. Simultaneously, light introduced through the opening 1130 can pass through the lens module. Here, the light passing through the lens module can be captured as an image in the image sensor.

[0302] The first mover 1200 may include a bobbin 1210 and an AF coil section 1220. The first mover 1200 may include a bobbin 1210 coupled to a lens module.

That is, the lens receiving portion 1211 may be threadedly engaged to the lens module. An adhesive may be applied between the lens module and the spool 1210. Here, the adhesive may be an epoxy resin that is cured by ultraviolet (UV) light or heat. That is, the lens module and the spool 1210 may be bonded to each other by UV-curable epoxy resin and / or heat-curable epoxy resin.

[0307] The spool 1210 may include a first drive unit coupling portion 1212 on which an AF coil unit 1220 is disposed. The first drive unit coupling portion 1212 may be integrally formed with the outer surface of the spool 1210. Alternatively, a plurality of first drive unit coupling portions 1212 may be formed continuously along the outer surface of the spool 1210, or may be spaced apart from each other at predetermined intervals. For example, the first drive unit coupling portion 1212 may be formed such that a portion of the outer surface of the spool 1210 is recessed to correspond to the shape of the AF coil unit 1220. Here, the AF coil unit 1220 may be directly wound onto the first drive unit coupling portion 1212. As a modification, the first drive unit coupling portion 1212 may be formed with an opening on its upper or lower side. Here, the AF coil unit 1220 may be pre-wound and then inserted and coupled to the first drive unit coupling portion 1212 through the opening side.

[0308] The spool 1210 may include an upper coupling portion 1213 coupled to the upper elastic member 1600. The upper coupling portion 1213 may be coupled to the inner frame 1620 of the upper elastic member 1600. In one example, a protrusion (not shown) of the upper coupling portion 1213 may be inserted into and coupled to a groove or hole (not shown) in the inner frame 1620 of the upper elastic member 1600. Here, the protrusion of the upper coupling portion 1213 may be thermally fused while inserted into the hole in the inner frame 1620 to secure the upper elastic member 1600.

[0309] The spool 1210 may include a lower coupling portion coupled to the lower elastic member 1700. The lower coupling portion may be coupled to the inner frame 1720 of the lower support member 1700. In one example, a protrusion (not shown) of the lower coupling portion may be inserted into and coupled to a groove or hole (not shown) in the inner frame 1720 of the lower support member 1700. Here, the protrusion of the lower coupling portion may be thermally fused while inserted into the hole in the inner frame 1720 to secure the lower support member 1700.

[0310] The AF coil unit 1220 may be located on the spool 1210. The AF coil unit 1220 may be coupled to the spool 1210. The AF coil unit 1220 may be guided by the first drive unit coupling portion 1212 and wound around the outer surface of the spool 1210. Alternatively, in another embodiment, the AF coil unit 1220 may include four independent coils, such that two adjacent coils are arranged at a 90° angular distance on the outer surface of the spool 1210. The AF coil unit 1220 may face the drive magnet unit 1320. The AF coil unit 1220 may be configured to electromagnetically interact with the drive magnet unit 1320. The AF coil unit 1220 may move the spool 1210 relative to the housing 1310 through electromagnetic interaction with the drive magnet unit 1320.

[0311] The AF coil unit 1220 may include a pair of leads 1221 for providing voltage. Here, the pair of leads 1221 of the AF coil unit 1220 can be connected to a first interior 1621 and a second interior 1622, respectively. That is, the AF coil unit 1220 can receive voltage through the upper elastic member 1600. With this structure, an electromagnetic field can be formed around the AF coil unit 1220 when voltage is supplied to it. The leads 1221 of the AF coil unit 1220 can be coupled to the first interior 1621 and the second interior 1622. Thus, the AF coil unit 1220 can be electrically connected to the first exterior 1611 and the third exterior 1613. In this case, voltage can be supplied to the AF coil unit 1220 from the substrate 1410 through the first support portion 1810 coupled to the first exterior 1611 and the third support portion 1830 coupled to the third exterior 1613. More specifically, the current supplied to the terminal 1412 of the substrate 1410 can be supplied to the AF coil unit 1220 by passing sequentially through the first support portion 1810, the first outer portion 1611, the first connecting portion 1631 and the second connecting portion 1632, and the first inner portion 1621. Additionally, the current supplied to the AF coil unit 1220 can be transmitted to the terminal 1412 of the substrate 1410 through the second inner portion 1622, the third connecting portion 1633 and the fourth connecting portion 1634, the third outer portion 1613, and the third support portion 1830.

[0312] like Figure 19 As shown, the lead 1221 of the AF coil unit 1220 can be coupled to the inner frame 1620 via solder element 1222. However, the coupling between the AF coil unit 1220 and the inner frame 1620 is not limited to soldering, and any other coupling method can be applied as long as it provides electrical continuity.

[0313] The second mover 1300 can be moved to compensate for hand tremors. The second mover 1300 can be located outside the first mover 1200, facing the first mover 1200. The second mover 1300 can move the first mover 1200, or can move together with the first mover 1200. The second mover 1300 can be movably supported by a stator 1400 and / or a base 1500 located below it. The second mover 1300 can be located within the internal space of the cover member 1100.

[0314] The second mover 1300 may include a housing 1310 and a drive magnet unit 1320. The second mover 1300 may include a housing 1310 located outside the coil 1210. In addition, the second mover 1300 may include a drive magnet unit 1320 positioned facing the AF coil unit 1220 and fixed to the housing 1310.

[0315] At least a portion of the housing 1310 may be formed to have a shape corresponding to the shape of the inner surface of the cover member 1100. Specifically, the outer surface of the housing 1310 may be formed to have a shape corresponding to the shape of the inner surface of the side plate 1120 of the cover member 1100. As an example, the housing 1310 may be in the form of a hexahedron including four sides. However, the housing 1310 may have any other shape, as long as it can be disposed within the cover member 1100. The housing 1310 may be formed of an insulating material and, considering production volume, may be formed as an injection-molded article.

[0316] The housing 1310 may be located outside the bobbin 1210. The housing 1310 may be provided with a drive magnet unit 1320. The housing 1310 may be located above the base 1500. The housing 1310 may be movable for OIS actuation and may be spaced apart from the cover member 1100 by a specific distance. However, in the AF model, the housing 1310 may be fixed to the base 1500. Alternatively, in the AF model, the housing 1310 may be omitted, and the drive magnet unit 1320 may be fixed to the cover member 1100. The upper support member 1600 may be coupled to the upper part of the housing 1310. The housing 1310 may be spaced apart from the bobbin 1210. However, in this case, a portion of the bobbin 1210 and a portion of the housing 1310 may come into contact with each other due to movement of the bobbin 1210.

[0317] The housing 1310 may include a first side surface portion 1301, a second side surface portion 1302, and a third side surface portion 1303 arranged continuously.

[0319] The upper and lower sides of the housing 1310 may be open to accommodate the first mover 1200, thereby allowing it to move in the vertical direction. The housing 1310 may include an internal space 1311 having open upper and lower sides. The bobbin 1210 may be movably disposed within the internal space 1311. That is, the internal space 1311 may have a shape corresponding to the shape of the bobbin 1210. Furthermore, the inner peripheral surface of the housing 1310 forming the internal space 1311 may be spaced apart from the outer peripheral surface of the bobbin 1210.

[0320] The housing 1310 may include a second drive unit coupling portion 1312, which is formed on a side surface of the housing with a shape corresponding to the shape of the drive magnet unit 1320, so as to accommodate the drive magnet 1320. The second drive unit coupling portion 1312 can accommodate and fix the drive magnet unit 1320. The drive magnet unit 1320 can be fixed to the second drive unit coupling portion 1312 using an adhesive (not shown). Meanwhile, the second drive unit coupling portion 1312 can be located on the inner peripheral surface of the housing 1310. This is advantageous from the perspective of the electromagnetic interaction between the second drive unit coupling portion and the AF coil unit 1220 located inside the drive magnet unit 1320. Additionally, as an example, the second drive unit coupling portion 1312 can have an open bottom shape. In this case, it is advantageous from the perspective of the electromagnetic interaction between the OIS coil unit 1420 located below the drive magnet unit 1320 and the drive magnet unit 1320. In this example, four second drive unit coupling portions 1312 may be provided. The drive magnet unit 1320 can be coupled to each of the four second drive unit coupling sections 1312.

[0321] The housing 1310 may include an upper coupling portion 1313 coupled to the upper elastic member 1600. The upper coupling portion 1313 may be coupled to the outer frame 1610 of the upper support member 1600. As an example, a protrusion of the upper coupling portion 1313 may be inserted into and coupled to a groove or hole (not shown) in the outer frame 1610 of the upper elastic member 1600. Here, the protrusion of the upper coupling portion 1313 is thermally fused while inserted into the hole in the outer frame 1610 to secure the upper support member 1600.

[0322] The housing 1310 may include a lower coupling portion coupled to the lower elastic member 1700. The lower coupling portion may be coupled to the outer frame 1710 of the lower elastic member 1700. As an example, a protrusion of the lower coupling portion may be inserted into and coupled to a groove or hole (not shown) in the outer frame 1710 of the lower elastic member 1700. Here, the protrusion of the lower coupling portion may be thermally fused while inserted into the hole in the outer frame 1710 to secure the lower elastic member 1700.

[0323] The drive magnet unit 1320 can be accommodated within the internal space of the cover member 1100. The drive magnet unit 1320 can face the AF coil unit 1220. The drive magnet unit 1320 can move the AF coil unit 1220 through electromagnetic interaction with it. The drive magnet unit 1320 can be located within the housing 1310. The drive magnet unit 1320 can be fixed to the second drive unit coupling portion 1312 of the housing 1310. The drive magnet unit 1320 can be disposed within the housing 1310 such that four magnets are arranged independently of each other, and two adjacent magnets form a 90-degree angle. That is, the drive magnet unit 1320 can effectively utilize the internal volume by means of magnets equidistantly mounted on the four side surfaces of the housing 1310. Additionally, the drive magnet unit 1320 can be bonded to the housing 1310 using an adhesive. However, this disclosure is not limited thereto.

[0324] As an example, stator 1400 may include substrate 1410 and OIS coil unit 1420. Stator 1400 may include substrate 1410 located between OIS coil unit 1420 and base 1500. In addition, stator 1400 may include OIS coil unit 1420 facing drive magnet 1320.

As an example, substrate 1410 may provide voltage to AF coil unit 1220 via lateral support member 1800 and upper elastic member 1600. Furthermore, substrate 1410 may be electrically connected to sensing coil unit 1910 via lateral support member 1800 and upper elastic member 1600.

[0326] As an example, substrate 1410 may include a main body portion 1411, a terminal portion 1412, and a through hole 1413. Substrate 1410 may include a terminal portion 1412 extending from one side of the main body portion 1411 and bent downward.

The OIS coil unit 1420 can be located on the substrate 1410. The OIS coil unit 1420 can be located between the base 1500 and the housing 1310. The OIS coil unit 1420 can face the driving magnet unit 1320. When a voltage is applied to the OIS coil unit 1420, the driving magnet unit 1320 and the housing 1310 to which the driving magnet unit 1320 is fixed can move together through the interaction between the OIS coil unit 1420 and the driving magnet unit 1320.

[0328] The OIS coil unit 1420 can be formed from a thin (FP) coil mounted on the substrate 1410. In this case, the OIS coil unit can be effective in miniaturizing the lens driving device (reducing the height in the z-axis direction, which is the optical axis direction).

[0329] As an example, the OIS coil unit 1420 can be configured to minimize interference with the OIS sensor unit 1920 located below it. The OIS coil unit 1420 can be positioned so as not to overlap with the OIS sensor unit 1920 in the vertical direction.

[0330] The OIS coil unit 1420 may include a coupling portion 1421 coupled to a lateral support member 1800. The coupling portion 1421 of the OIS coil unit 1420 may be coupled to the lateral support member 1800. For example, the coupling portion 1421 may be formed as a through-hole, and the lateral support member 1800, formed of a wire, may pass through the coupling portion 1421. The portion of the lateral support member 1800 that has passed through the coupling portion 1421 may be coupled to the OIS coil unit 1420 by soldering.

The foreign object collector may be located on the upper surface of the base 1500 and may include an adhesive material to collect foreign objects in the interior space defined by the cover member 1100 and the base 1500.

[0336] The base 1500 may include a sensor mounting section 1530 to which an OIS sensor unit 1920 is coupled. That is, the OIS sensor unit 1920 may be mounted on the sensor mounting section 1530. Here, the OIS sensor unit 1920 can sense the magnetic field of the drive magnet unit 1320 coupled to the housing 1310, thereby detecting horizontal movement or tilting of the housing 1310. As an example, two sensor mounting sections 1530 may be provided. Each of the two sensor mounting sections 1530 may be provided with an OIS sensor unit 1920. In this case, the OIS sensor unit 1920 may include a first axis sensor and a second axis sensor arranged to sense both the x-axis and y-axis movements of the housing 1310.

[0337] Support members 1600, 1700, and 1800 may interconnect any two or more of the first mover 1200, second mover 1300, stator 1400, and base 1500. Support members 1600, 1700, and 1800 elastically interconnect any two or more of the first mover 1200, second mover 1300, stator 1400, and base 1500 to support the respective elements so that they can move relative to each other. Support members 1600, 1700, and 1800 may be configured such that at least a portion thereof is elastic. In this case, support members 1600, 1700, and 1800 may be referred to as "elastic members" or "springs."

[0338] For example, support members 1600, 1700, and 1800 may include an upper elastic member 1600, a lower elastic member 1700, and a lateral support member 1800.

[0343] The upper elastic member 1600 may include a first support unit and a second support unit. Here, the first support unit may be coupled to both the housing 1310 and the bobbin 1210, while the second support unit may not be coupled to the bobbin 1210, but may only be coupled to the housing 1310. That is, the first support unit may include, for example, a first outer portion 1611, a first inner portion 1621, and a first connecting portion 1631. Additionally, the second support unit may include a second outer portion 1612.

[0344] The outer frame 1610 may include a first outer portion 1611 and a second outer portion 1612 spaced apart from each other.

[0355] In one embodiment, the inner frame 1620 can be configured as a structure divided into two parts by a virtual spring.

[0356] In this embodiment, by coupling the first inner coupling portion 6211, the second inner coupling portion 6212, and the third inner coupling portion 6213 with the aid of the virtual portion 1625, the operability of the upper support member 1600 can be improved and its deformation can be prevented. In addition, the flatness of the assembly of the spool 1210 can be improved, thereby preventing tilting defects and defective strokes during autofocus drive.

[0362] As an example, the lower elastic member 1700 can be integrally formed. However, this disclosure is not limited thereto. In a modified example, the lower elastic member 1700 can be divided into a pair of members and, for example, can be used to supply voltage to the AF coil unit 1220.

[0363] The lateral support member 1800 can be coupled to the upper support member 1600 and the base plate 1410. The lateral support member 1800 can be electrically connected to the upper support member 1600 and the base plate 1410. The lateral support member 1800 can elastically support the housing 1310 relative to the base 1500. The lateral support member 1800 can be coupled to the stator 1400 and / or the base 1500 on one side, and can be coupled to the upper support member 1600 and / or the housing 1310 on the other side. The lateral support member 1800 can be coupled to the stator 1400 and the upper support member 1600. The lateral support member 1800 can be coupled to the stator 1400 on one side and to the upper support member 1600 on the other side. With this structure, the lateral support member 1800 can elastically support the second mover 1300 relative to the stator 1400, such that the second mover 1300 can move or tilt in the horizontal direction. As an example, the lateral support member 1800 may include multiple lines. Alternatively, as a modification, the lateral support member 1800 may include multiple leaf springs. On the other hand, the lateral support member 1800 may be integrally formed with the upper elastic member 1600.

[0364] The lateral support member 1800 may include a first support portion 1810, a second support portion 1820, a third support portion 1830, and a fourth support portion 1840. The lateral support member 1800 may include a first support portion 1810 coupled to a first exterior 1611.

[0365] The lateral support member 1800 or the upper elastic member 1600 may include an impact-absorbing portion (not shown) for absorbing shocks. The impact-absorbing portion may be disposed on at least one of the lateral support member 1800 and the upper elastic member 1600. The impact-absorbing portion may be a separate component such as a shock absorber. Alternatively, the impact-absorbing portion may be implemented by changing the shape of a portion of either the lateral support member 1800 or the upper elastic member 1600.

[0366] A sensor unit may be provided for at least one of autofocus feedback and image stabilization feedback. The sensor unit may sense the position or movement of either the first mover 1200 or the second mover 1300.

[0367] As an example, the sensor unit may include an AF sensor unit and an OIS sensor unit 1920. The AF sensor unit can sense the vertical movement of the spool 1210 relative to the housing 1310 to provide information for AF feedback. The OIS sensor 1920 can provide information for OIS feedback by sensing the horizontal movement or tilt of the second mover 1300.

[0368] The AF sensor unit may include a sensing coil unit 1910, a high-frequency current application unit (not shown), and a voltage sensing unit (not shown).

[0369] The sensing coil unit 1910 may be located on the housing 1310. The sensing coil unit 1910 may be located around the upper part of the housing 1310. The sensing coil unit 1910 may be placed along the upper end of the housing 1310. For example, the sensing coil unit 1910 may be in the form of a closed curve, but is not limited thereto. The sensing coil unit 1910 may be spaced apart from the AF coil unit 1220. Using this structure, when a voltage is applied to the AF coil unit 1220, an induced voltage can be generated in the sensing coil unit 1910. The voltage induced in the sensing coil unit 1910 varies depending on the distance between the sensing coil unit 1910 and the AF coil unit 1220. That is, the voltage induced in the sensing coil unit 1910 can vary depending on the distance between the sensing coil unit 1910 and the AF coil unit 1220. In an embodiment, the movement and / or position of the spool 1210 can be detected by measuring the voltage induced in the sensing coil unit 1910 using the above-described characteristics. The movement and / or position of the spool 1210 detected in this way can be used for the autofocus feedback function.

[0370] The sensing coil unit 1910 can be electrically connected to the second external component 1612 and the fourth external component 1614. In this case, the sensing coil unit 1910 and the substrate 1410 can be electrically connected to each other via the second support portion 1820 coupled to the second external component 1612 and the fourth support portion 1840 coupled to the fourth external component 1614. Using this structure, the induced voltage induced in the sensing coil unit 1910 by the high-frequency current supplied to the AF coil unit 1220 can be measured. In addition, the induced current induced in the sensing coil unit 1910 by the high-frequency current supplied to the AF coil unit 1220 can be transmitted to the terminal portion 1412 of the substrate 1410 via the second external component 1612 and the second support portion 1820. Alternatively, the induced current induced in the sensing coil unit 1910 by the high-frequency current supplied to the AF coil unit 1220 can be transmitted to the terminal portion 1412 of the substrate 1410 via the fourth external component 1614 and the fourth support portion 1840.

[0371] like Figure 18 As shown, the lead 1911 of the sensing coil unit 1910 can be coupled to the outer frame 1610 using solder element 1912. However, the coupling between the sensing coil unit 1910 and the outer frame 1610 is not limited to soldering, and any type of coupling that secures the two can be applied.

[0372] The high-frequency current application unit can apply a high-frequency current to the AF coil unit 1220. That is, the high-frequency current application unit can apply a high-frequency current, such as a pulsed current, to the AF coil unit 1220. Here, the high-frequency current applied to the AF coil unit 1220 can induce a voltage in the sensing coil unit 1910 without affecting the movement of the spool 1210. In other words, the high-frequency current application unit can generate an induced voltage in the sensing coil unit 1910 by applying a high-frequency current to the AF coil unit 1220 without affecting the autofocus drive of the spool 1210. The high-frequency current application unit can provide high-frequency current to the AF coil unit 1220 according to a predetermined time interval.

[0373] The voltage sensing unit can sense the voltage induced in the sensing coil unit 1910. That is, the voltage sensing unit can sense the voltage induced in the sensing coil unit 1910, and the sensed value can be sent to the controller so that the controller can determine the position of the drum 1210.

[0374] The operation of the camera module according to this embodiment will be described below.

[0375] First, the autofocus function of the camera module according to this embodiment will be described. When voltage is supplied to the AF coil unit 1220, the AF coil unit 1220 moves relative to the drive magnet unit 1320 through the electromagnetic interaction between the AF coil unit 1220 and the drive magnet unit 1320. Here, the spool 1210 coupled to the AF coil unit 1220 moves integrally with the AF coil unit 1220. That is, the spool 1210, to which the lens module is coupled, moves up and down relative to the housing 1310. This movement of the spool 1210 causes the lens module to move closer to or further away from the image sensor, thereby performing focus adjustment for the subject.

[0376] On the other hand, autofocus feedback can be applied to achieve more precise autofocus functionality of the camera module according to this embodiment. A voltage is induced in the sensing coil unit 1910 mounted on the housing 1310 by a high-frequency current applied to the AF coil unit 1220. Furthermore, the value of the voltage induced in the sensing coil unit 1910 can change when the spool 1210 moves relative to the housing 1310 by the drive current applied to the AF coil unit 1220. Here, the supply of high-frequency current to the AF coil unit 1220 can be performed at predetermined time intervals. Meanwhile, the voltage sensing unit senses the value of the voltage induced in the sensing coil unit 1910 and sends this value to the controller. The controller determines whether to perform additional movement of the spool 1210 based on the received voltage value. Since this processing is performed in real time, the autofocus functionality of the camera module according to this embodiment can be performed more precisely through autofocus feedback.

[0377] The image stabilization function of the camera module according to this embodiment will be described. When voltage is supplied to the OIS coil unit 1420, the drive magnet unit 1320 moves relative to the OIS coil unit 1420 through the electromagnetic interaction between the OIS coil unit 1420 and the drive magnet unit 1320. Here, the housing 1310 coupled to the drive magnet unit 1320 moves integrally with the drive magnet unit 1320. That is, the housing 1310 moves in the horizontal direction relative to the base 1500. At the same time, the housing 1310 can be tilted relative to the base 1500. This movement of the housing 1310 causes the lens module to move relative to the image sensor in a direction parallel to the direction in which the image sensor is placed (a direction orthogonal to the optical axis of the lens module), thereby enabling the image stabilization function to be executed.

[0378] On the other hand, hand shake compensation feedback can be applied to more accurately implement the hand shake compensation function of the camera module according to this embodiment. An OIS sensor 1920 mounted on the base 1500 senses the magnetic field of the drive magnet unit 1320 fixed to the housing 1310. Furthermore, when the housing 1310 moves relative to the base 1500, the amount of the magnetic field sensed by the OIS sensor 1920 changes. Simultaneously, a pair of OIS sensors 1920 sense the amount or position of the housing 1310 in the horizontal direction (x-axis and y-axis directions) in the manner described above, and send the sensed values ​​to the controller. The controller determines whether to perform additional movement of the housing 1310 based on the received sensed values. Since the above processing is performed in real time, the hand shake compensation function of the camera module according to this embodiment can be executed more accurately through hand shake compensation feedback.

For example, the second holder 800 can be electrically connected to the circuit board 250 or 1410 of the lens drive device, and the controller 820 mounted on the second holder 800 can be electrically connected to the second position sensor 240 or OIS sensor unit 1920 and the second coil 230 or OIS coil unit 1420 via the circuit board 250 or 1410.

[0395] The controller 830 can output a drive signal capable of performing hand shakiness compensation to the OIS movable unit of the lens drive device based on the output signal provided from the second position sensor 240 or the OIS sensor unit 1920 of the lens drive device.

[0396] Connector 840 can be electrically connected to second retainer 800 and may include a port for electrical connection to an external device.

[0397] Furthermore, the lens driving device 100 according to this embodiment may include an optical instrument whose purpose is to form an image of an object in space using the properties of light, such as reflection, refraction, absorption, interference, or diffraction, which increase visibility; to record and reproduce images through the lens; or to perform optical measurement or image propagation or transmission, etc. For example, the optical instrument according to this embodiment can be applied to mobile phones, cellular phones, smartphones, portable smart devices, digital cameras, laptop computers, digital broadcasting terminals, personal digital assistants (PDAs), navigation systems, etc., but is not limited thereto, and any device used for capturing images or photographs can be used.
