Summary of the Invention
[0003] Technical issues
[0004] The embodiments provide a camera device and optical instrument capable of achieving a stable and desired holding force and performing stable OIS operation.
[0005] Technical solution
[0006] A camera device according to an embodiment includes: a fixed unit; a movable unit including an image sensor and a lens; a tilt guide unit disposed between the fixed unit and the movable unit; and an elastic member connecting the fixed unit to the movable unit, wherein the elastic member includes a first connecting portion connected to the movable unit, a second connecting portion connected to the fixed unit, and a connecting portion connecting the first connecting portion to the second connecting portion, wherein the tilt guide unit is pushed toward the movable unit by the elastic member, and wherein the movable unit tilts about a first axis perpendicular to the optical axis or a second axis perpendicular to the optical axis and intersecting the first axis.
[0007] The tilting guide unit may include an opening, and the moving unit may include an extension connected to the first connecting portion, with at least a portion of the extension disposed in the opening in the tilting guide unit.
[0008] The first connecting portion may have a height difference with the second connecting portion in the optical axis direction, and the height difference may be less than the length of the extension portion in the optical axis direction.
[0009] The moving unit may include a sensor base and a circuit board disposed on the sensor base, and an image sensor disposed on the circuit board. The tilting guide unit may include an opening, and the sensor base may include an extension that extends through the opening in the tilting guide and is coupled to a first coupling portion. The fixing unit may include an opening through which the extension and the first coupling portion are exposed.
[0010] At least a portion of the extension may be disposed in an opening in the fixing unit. The fixing unit may include a receiving portion recessed from its lower surface, and a second connecting portion may be disposed in the receiving portion. The camera device may include a shielding member disposed on the lower surface of the fixing unit to cover the opening in the fixing unit, and the shielding member being spaced apart from the elastic member.
[0011] The elastic member can be a leaf spring. The elastic member can have a restoring force, which can be a force that pulls the moving unit toward the fixed unit. The image sensor can be positioned closer to the first connecting portion than to the second connecting portion.
[0012] The tilting guide unit may include a first boss disposed on the upper surface of the tilting guide unit along a first axis and a second boss disposed on the lower surface of the tilting guide unit along a second axis, and the first connecting portion may be positioned higher than the lowest end of the second boss. The second connecting portion may be positioned lower than the lowest end of the second boss.
[0013] A camera device according to another embodiment includes: a fixed unit; a movable unit including a sensor base, an image sensor disposed on the sensor base, and a lens; a tilt guide unit disposed between the fixed unit and the movable unit and including an opening; and an elastic member disposed below the tilt guide unit and connecting the fixed unit to the movable unit, wherein the sensor base includes an extension extending through the opening of the tilt guide unit and connected to the elastic member, and the movable unit is tilted about a first axis perpendicular to the optical axis or a second axis perpendicular to the optical axis and intersecting the first axis. The elastic member includes a first connecting portion connected to the extension of the sensor base, a second connecting portion connected to the fixed unit, and a connecting portion connecting the first connecting portion to the second connecting portion, and the image sensor is positioned closer to the first connecting portion than to the second connecting portion.
[0014] A camera device according to another embodiment includes: a fixed unit; a movable unit including an image sensor and a lens disposed on the image sensor; a tilt guide unit disposed between the fixed unit and the movable unit; and an elastic member including a first connecting portion connected to the movable unit, a second connecting portion connected to the fixed unit, and a connecting portion connecting the first connecting portion to the second connecting portion, wherein the second connecting portion is positioned lower than the first connecting portion, the tilt guide unit is pushed toward the movable unit by the elastic member, and the movable unit is tilted about a first axis perpendicular to the optical axis or a second axis perpendicular to the optical axis and intersecting the first axis.
[0015] Beneficial effects
[0016] In this implementation, an elastic member is used instead of a magnetic material to generate the holding force for pressing the tilting guide unit that supports the OIS moving unit.
[0017] In this implementation, the use of an elastic member prevents magnetic field interference between the magnetic material and the driving magnet, thereby achieving a stable and desired holding force.
[0018] In this implementation, the selection of the axis for tilting the module can be easy and free due to the use of elastic members, and a linear holding force can be achieved relative to the stroke or displacement of the OIS moving unit.
[0019] The implementation method can reduce the space required to tilt the sensor base, which serves as the OIS moving unit, for shaky compensation and reduce the size of the camera device.
[0020] The implementation method can reduce the number of parts and lighten the weight of the camera device.
[0021] Furthermore, in the implementation, since the OIS moving unit is tilted using a tilting guide unit, the OIS moving unit can be tilted stably, precisely, and accurately compared to examples that only use ball members or shaft members, thereby improving the reliability of OIS operation.

[0067] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.
[0068] In the following description of the embodiments, it will be understood that when each element is referred to as "on" or "below" another element, the element may be directly on or below the other element, or may be indirectly configured such that one or more intermediate elements are also present. Additionally, when an element is referred to as "on" or "below," it may include both "below" and "on" the element.
[0069] Furthermore, the terms “first,” “second,” “upper / upper part / above,” and “lower / lower part / below” are used herein only to distinguish one object or element from another, and do not necessarily require or relate to any physical or logical relationship or order between such objects or elements. Wherever possible, the same reference numerals will be used throughout the accompanying drawings to refer to the same parts.
[0070] Furthermore, the terms "comprising," "including," and "having" as described herein should be interpreted as not excluding other elements, but rather including such other elements, because the corresponding element may be inherent unless otherwise specified. Additionally, the term "corresponding to" as described herein may encompass at least one of the meanings of "facing" and "overlapping."
[0071] In the following description, a camera device according to an embodiment and an optical instrument including the camera device will be described with reference to the accompanying drawings. For ease of description, the camera device according to the embodiment will be described using a Cartesian coordinate system (x, y, z), but the embodiment is not limited to this, and other coordinate systems may be used for description. In the corresponding drawings, the X-axis and Y-axis may be axes perpendicular to the Z-axis, where the Z-axis is the optical axis (OA) direction.
[0072] Alternatively, the Z-axis direction, which serves as the optical axis OA, can be defined as one of a first direction, a second direction, and a third direction; the X-axis direction can be defined as another of the first to third directions; and the Y-axis direction can be defined as the remaining one of the first to third directions. For example, the first direction can be a direction perpendicular to the imaging area of the image sensor.
[0073] Furthermore, the X-axis (or Y-axis) can be referred to as the "first horizontal axis," the direction of the X-axis (or Y-axis) can be referred to as the "first horizontal direction," the Y-axis (or X-axis) can be referred to as the "second horizontal axis," and the direction of the Y-axis (or X-axis) can be referred to as the "second horizontal direction." For example, the direction of the optical axis can be the direction of the optical axis or a direction parallel to the optical axis. Additionally, the direction of the first axis can be a direction parallel to the first axis, and the direction of the second axis can be a direction parallel to the second axis.
[0074] Alternatively, for example, the optical axis can be the optical axis of a lens mounted in the lens barrel. Alternatively, for example, the optical axis can be an axis perpendicular to the image capture area of the image sensor and extending through the center of the image capture area. In the following text, the term "terminal" may be alternatively referred to as a pad, electrode, or conductive layer.
[0075] Furthermore, in the implementation, in the connection between the boss and the hole used to connect the two configurations to each other, one configuration can be a connecting boss (or a connecting hole), and the other configuration can be a connecting hole (or a connecting boss) corresponding to that configuration.
[0076] The camera device according to the embodiment can perform image stabilization and autofocus functions. Image stabilization can be a function that moves the lens in a direction perpendicular to the optical axis or tilts the lens relative to the optical axis to eliminate vibrations (or movements) caused by the user's hand tremors. Autofocus can be a function that automatically focuses on the object by moving the lens along the optical axis according to the distance to the object, thereby enabling the image sensor to obtain a clear image of the object. In the following text, "camera device" may be alternatively referred to as "camera," "actuator," "camera module," "image capture device," or "shooting device."

[0078] Reference Figures 1 to 11d The camera device 200 may include a fixed unit, a movable unit, and a support unit configured to support the movable unit relative to the fixed unit. The movable unit may include an AF movable unit and an OIS movable unit 100. The OIS movable unit 100 may alternatively be referred to as a "moving unit," "shaking unit," or "motion unit."
[0079] The fixing unit can be a fixed element. That is, the fixing unit may not move along the optical axis. Alternatively, the fixing unit may not move or tilt in a direction perpendicular to the optical axis. In addition, the configuration connected to the fixing unit can also be a fixing unit.
[0080] The fixing unit may include a housing 210. The fixing unit may include a cover member 300. For example, the fixing unit may include a configuration disposed on or connected to the housing 210 or the cover member 300. For example, the fixing unit may include at least one of a magnet 310 or a motion suppression portion 80 disposed on the housing 210.
[0081] The AF moving unit can move relative to the fixed unit along the optical axis. For example, the AF moving unit may include a spool 110. In another embodiment, the AF moving unit may also include a configuration (e.g., a magnet 130) coupled to the spool 110. In another embodiment, the AF moving unit may also include a lens module 400 coupled to the spool 110 (see...). Figure 17 ).
[0082] OIS mobile unit 100 (see also) Figure 2aThe OIS moving unit can move left or right and / or tilt relative to the fixed unit about a first axis (e.g., pitch) intersecting the optical axis. Additionally, the OIS moving unit can move left or right and / or tilt relative to the fixed unit about a second axis (e.g., yaw) intersecting the optical axis. For example, the first axis can be perpendicular to the optical axis direction, and the second axis can be perpendicular to both the optical axis direction and the first axis. For example, the first axis can intersect the X-axis or the Y-axis. For example, the second axis can intersect the X-axis or the Y-axis. For example, the first axis and the second axis can be perpendicular to each other. In another embodiment, for example, the first axis can be one of the X-axis and the Y-axis, and the second axis can be the other of the X-axis and the Y-axis.
[0083] For example, the OIS motion unit 100 may include an AF motion unit. Additionally, the OIS motion unit may include an image sensor 810. The OIS motion unit 100 may include a circuit board 800 on which the image sensor 810 is disposed. Furthermore, the OIS motion unit 100 may include a sensor base 270 on which at least a portion of the circuit board 800 is disposed. Additionally, the OIS motion unit may include a retainer 140 coupled to the sensor base 270.
[0084] The OIS moving unit 100 may be referred to as the first moving unit (or first motion unit), and the AF moving unit may alternatively be referred to as the second moving unit (or second motion unit). For example, the first moving unit may include the sensor base 270 and the circuit board 800.
[0085] Alternatively, for example, the OIS movement unit 100 may include a configuration that is disposed on or coupled to at least one of the holder 140, the sensor base 270, or the circuit board 800. For example, the OIS movement unit 100 may include a filter 610 disposed on the holder 140.
[0086] For example, the OIS motion unit 100 may include at least one of the following: an image sensor 810, sensors 170 and 240, coils 120 and 230, circuit element 815, or controller 830 disposed on a circuit board 800.
[0087] Additionally, the OIS motion unit 100 may include a motion module (or tilt module). For example, the motion module (or tilt module) may include a lens module 400 and an image sensor 810. Furthermore, for example, the motion module (or tilt module) may include a sensor base 270. Additionally, for example, the motion module (or tilt module) may also include at least one of a retainer 140 or a circuit board 800. For example, the motion module (or tilt module) may tilt about a first axis or a second axis. For example, the motion module may be alternatively referred to as a "mover".
[0088] The support unit can support the OIS moving unit relative to the fixed unit. For example, the support unit may include a tilting guide unit 60. In another embodiment, the support unit may also include a rolling member (e.g., a ball member) or a sliding member (e.g., a shaft). Additionally, the support unit may include an elastic member 30 that connects the OIS moving unit to the fixed unit.
[0089] A portion (or end) of the elastic member 30 may be coupled to the OIS moving unit (e.g., sensor base 270), and another portion (another end) of the elastic member 30 may be coupled to the fixed unit (e.g., housing 210).
[0090] The spool 110 is configured to receive a lens or lens barrel and may be disposed in the retainer 140. Alternatively, the spool 110 may be disposed in the cover member 300. The spool 100 may be disposed in the cover member 300. The spool 110 may be alternatively referred to as a "lens retainer" or "lens carrier".
[0091] The spool 110 can move along the optical axis. For example, the spool 110 can move along a first direction (e.g., the z-axis direction) through the electromagnetic interaction between the coil 120 and the magnet 130. The coil 120 and the magnet 130 can be an AF drive unit configured to move or drive the AF movement unit. Alternatively, the spool 110 can be included in the OIS movement unit 100, and the spool 110 can tilt or rotate by a predetermined angle about a first axis or a second axis.
[0092] Reference Figure 5 The spool 110 may include an opening 101 for attachment to the lens module 400. The opening 101 may be a hole or hollow portion formed by passing through the spool 110 along the optical axis. The shape of the opening 101 in the spool 110 may match the shape of the lens module 400 to which it is mounted or attached, and may be, but is not limited to, circular, elliptical or polygonal.
[0093] although Figure 1Although not shown, the spool 110 may include at least one stop disposed on at least one of its upper or lower surfaces. The stop of the spool 110 may protrude from the upper (or lower) surface of the spool 110 in a first direction or an upward (or downward) direction, and may prevent the upper (or lower) surface of the spool 110 from directly colliding with the inner surface of the upper plate 301 of the cover member 300 (or the lower portion of the retainer 140).
[0094] The spool 110 may include a mounting portion 115 configured to allow a magnet 130 to be mounted or disposed thereon. For example, the mounting portion 115 may be a recess recessed from the outer surface of the spool 110.
[0095] Reference Figure 6 The spool 110 may include a plurality of side surfaces 110A to 110D or an outer surface. For example, the spool 110 may include a first side surface 110A, a second side surface 110B, a third side surface 110C, and a fourth side surface 110D.
[0096] For example, the second side surface 110B may face the first side surface 110A or may be opposite to the first side surface 110A relative to the optical axis OA. The third side surface 110C and the fourth side surface 110D may be located between the first side surface 110A and the second side surface 110B. For example, the fourth side surface 110D may face the third side surface 110C or may be opposite to the third side surface 110C relative to the optical axis OA. Figure 6 In the illustration, spool 110 is shown to include four side surfaces, but in another embodiment, the spool may include three, five, or more side surfaces.
[0097] For example, the seating portion 115 may be formed on the first side surface 110A of the spool. For example, the lower portion of the seating portion 115 may be closed instead of leading to the lower surface of the spool 110. Additionally, the upper portion of the seating portion 115 may be closed instead of leading to the upper surface of the spool 110. In another embodiment, for example, the seating portion 115 may include an opening leading to at least one of the upper or lower surfaces of the spool 110.
[0098] The spool 110 may include a receiving portion 112 configured to receive at least a portion of the rolling member 21. For example, at least a portion of the receiving portion 112 may be disposed on a first side surface 110A of the spool 110. The receiving portion 112 may be a recess that is recessed from the outer surface of the spool 110 (e.g., the first side surface 110A). The receiving portion 112 may alternatively be referred to as a "receiving recess," "recess," or "guide recess." A lubricant (e.g., grease) may be disposed in the receiving portion 112 of the spool 110 to reduce friction with the rolling member 21.
[0099] For example, the spool 110 may include a first receiving portion 112A configured to receive a rolling member 21A and a second receiving portion 112B configured to receive a rolling member 21B. For example, a seating portion 115 may be disposed between the first receiving portion 112A and the second receiving portion 112B.
[0100] For example, the first receiving portion 112A (or the second receiving portion 112B) may include an opening leading to the upper surface of the spool 110. In another embodiment, the upper portions of the receiving portions 112A and 112B may be closed instead of leading to the upper surface of the spool 110. For example, the lower portions of the receiving portions 112A and 112B may be closed instead of leading to the lower surface of the spool 110. For example, the receiving portion 112 may be formed to extend along the optical axis. For example, the receiving portion 112 may extend along the optical axis to form between the upper and lower surfaces of the spool 110.
[0101] For example, when viewed from above, the shape of the receiving portion 112 may be, but is not limited to, a triangle, and the shape of the receiving portion may be a polygon (e.g., a quadrilateral or a pentagon). Alternatively, for example, when viewed from above, the receiving portion 112 may have a “V-shaped” or “U-shaped” shape.
[0102] The magnet 130 can be disposed on, connected to, or fixed to the spool 110. For example, the magnet 130 can be disposed on or connected to the first side surface 110A of the spool 110. For example, the magnet 130 can be disposed in or connected to the seating portion 115 of the spool 110. For example, the magnet 130 can be disposed between the first rolling member 21A and the second rolling member 21B.
[0103] The magnet 130 may have a shape corresponding to the first side surface 110A of the spool 110, such as a cuboid shape. In another embodiment, for example, at least one of the opposite ends of the magnet 130 may be tapered. For example, the magnet 130 may include a first side surface 13A facing the coil 120 and a second side surface 13B opposite to the first side surface 13A. The first side surface 13A of the magnet 130 may be exposed from the first side surface 110A of the spool 110.
[0104] Furthermore, to enhance the electromagnetic force, magnet 130 can be a quadrupole magnet. For example, magnet 130 may include two N poles and two S poles. For example, magnet 130 may include a first magnet having N and S poles, a second magnet having S and N poles, and a partition wall disposed between the first magnet and the second magnet. The partition wall, as a substantially non-magnetic portion, may include a section with almost no polarity, which may be filled with air or made of a non-magnetic material, and may be referred to as a "neutral region". For example, the first magnet and the second magnet may face each other along the optical axis, and the first magnet and the second magnet may be arranged to face different polarities along the optical axis.
[0105] In another embodiment, magnet 130 may be a bipolar magnet having two different polarities and an interface naturally formed between the different polarities. For example, in another embodiment, magnet 130 may include an N pole and a S pole. For example, magnet 130 may be a bipolar magnet having N poles and S poles separated or arranged along the optical axis. In another embodiment, magnet 130 may be a bipolar magnet having N poles and S poles separated in a direction perpendicular to the optical axis.
[0106] Retainer 140 may be disposed in cover member 300. Retainer 140 may be disposed in housing 210. Retainer 140 may include a cavity configured to receive spool 110. Retainer 140 may include an opening 30A corresponding to an opening 101 in spool 110. For example, opening 30A may be a through-hole or hollow portion configured to expose at least a portion of spool 110 (or lens module 400). Alternatively, for example, opening 30A in retainer 140 may expose the image capture area of image sensor 810. Retainer 140 may alternatively be referred to as "housing". For example, opening 30A may be located in the center or central region of retainer 140. For example, opening 30A in retainer 140 may be a through-hole or hollow portion formed through retainer 140 along the optical axis. The opening 30A in the retainer 140 may have a shape corresponding to the shape of the spool 110, such as, but not limited to, a polygonal shape (e.g., a quadrilateral or an octagonal shape) or a circular shape (or an elliptical shape), and may have various shapes.
[0107] The retainer 140 may include a plurality of side portions 41A to 41D. The retainer 140 may include a corner located between two adjacent side portions and connecting the two adjacent side portions to each other. The retainer 140 may include a first side portion 41A corresponding to or opposite to a first side surface 110A of the spool 110, a second side portion 41B corresponding to or opposite to a second side surface 110B of the spool 110, a third side portion 41C corresponding to or opposite to a third side surface 110C of the spool 110, and a fourth side portion 41D corresponding to or opposite to a fourth side surface 110D of the spool 110.
[0108] The first side portion 41A (or the first side surface or the first outer surface) of the retainer 140 can be positioned relative to the optical axis and opposite to the second side portion 41B (or the second side surface or the second outer surface) of the retainer 140, and the third side portion 41C (or the third side surface or the third outer surface) of the retainer 140 can be positioned relative to the optical axis and opposite to the fourth side portion 41D (or the fourth side surface or the fourth outer surface) of the retainer 140. Each of the first side portions 41A to the fourth side portions 41D of the retainer 140 can be arranged parallel to a corresponding side plate in the side plate 302 of the cover member 300.
[0109] Reference Figure 7a and Figure 7b The retainer 140 may include a mounting portion 142A on which the coil 120 is disposed. For example, the mounting portion 142A may be disposed on or formed on a first side portion 41A of the retainer 140. For example, the mounting portion 142A may be a through-hole formed through the first side portion 41A of the retainer 140. Since the mounting portion 142A is a through-hole, a portion of the retainer 140 may not be inserted between the coil 120 and the magnet 130, which can increase the electromagnetic force between the magnet 130 and the coil 120. In addition, since a portion of the retainer 140 may not be inserted between the position sensor 170 and the magnet 130, the output of the position sensor 170 can be increased, and the sensitivity of the position sensor 170 can be improved. Furthermore, since a portion of the retainer 140 is not inserted between the coil 120 and the magnet 130, the size of the camera device can be reduced. In another embodiment, the seating portion 142A may be a recess that is recessed from the outer surface (or inner surface) of the first side portion 41A of the retainer 140.
[0110] The holder 140 may include a recess 142 in which at least a portion of the circuit board 800, such as at least a portion of the second substrate 802, is disposed. Because at least a portion of the second substrate 802 is disposed in the recess 142 of the holder 140, the second substrate 802 and the magnetic material 82 may not protrude excessively from the outer surface of the first side portion 41A of the holder 140. That is, the second substrate 802 and the magnetic material 82 may protrude less than the sum of the thickness of the second substrate 802 and the thickness of the magnetic material 82 relative to the outer surface of the first side portion 41A of the holder 140. This prevents an increase in the size of the camera device 200 in the direction perpendicular to the optical axis.
[0111] The retainer 140 may include a receiving portion 116 configured to allow at least another portion of the rolling member 21 to be disposed or received therein. For example, at least a portion of the receiving portion 116 may be disposed on a first side portion 41A of the retainer 140. The receiving portion 116 may be a recess that is recessed from an inner surface of the retainer 140 (e.g., the inner surface of the first side portion 41A). The receiving portion 116 may alternatively be referred to as a “receiving recess,” a “recess,” or a “guide recess.” At least a portion of the receiving portion 116 of the retainer 140 may correspond to, be opposite to, or overlap with the receiving portion 112 of the spool 110.
[0112] For example, the retainer 140 may include a first receiving portion 116A and a second receiving portion 116B, the first receiving portion 116A being configured to receive at least another portion of the first rolling members 21A (B1 and B2), and the second receiving portion 116B being configured to receive at least another portion of the second rolling members 21B (B3 and B4). For example, the seating portion 142A of the retainer 140 may be disposed between the first receiving portion 116A and the second receiving portion 116B of the retainer 140.
[0113] For example, the first receiving portion 116A (or the second receiving portion 116B) may include an opening leading to the upper surface of the retainer 140. In another embodiment, the upper portion of the receiving portion 116 may be closed instead of leading to the upper surface of the retainer 140. For example, the lower portion of the receiving portion 116 may be closed instead of leading to the lower surface of the retainer 140. For example, the receiving portion 116 may be formed to extend along an optical axis. For example, the receiving portion 116 may extend along an optical axis to be formed between the upper and lower surfaces of the retainer 140. For example, when viewed from above, the shape of the receiving portion 116 of the retainer 140 may be, but is not limited to, a triangle, and the shape of the receiving portion may be polygonal (e.g., quadrilateral or pentagonal). Alternatively, for example, when viewed from above, the receiving portion 116 may have a “V” or “U” shape.
[0114] For example, when viewed along the optical axis or from above, the receiving portion 116 may be opposite to or overlap with the upper plate 301 of the cover member 300. For example, at least a portion of the upper plate 301 of the cover member 300 may cover the receiving portion 116.
[0115] The camera assembly 200 may include a rolling member 21 disposed between the linear shaft 110 and the retainer 140. The rolling member 21 may alternatively be referred to as a "ball member", "ball" or "ball bearing".
[0116] At least a portion of the rolling member 21 can contact the spool 110 and the retainer 140, and can roll or rotate between the spool 110 and the retainer 140 to support the movement of the spool 110 in the optical axis direction. When the spool 110 moves along the optical axis direction, the rolling member 21 can reduce the friction between the spool 110 and the retainer 140. Due to the rolling or rotating of the rolling member 21, the spool 110 can slide along the optical axis direction while in contact with the rolling member 21.
[0117] For example, the rolling member 21 can be made of metal, plastic or resin, but is not limited to these. The rolling member 21 can have a circular shape and a diameter large enough to support the movement of the spool 110 in the optical axis direction.
[0118] For example, the rolling member 21 may be disposed between the outer surface of the spindle 110 and the inner surface of the retainer 140. For example, the rolling member 21 may be disposed between the first side surface 110A of the spindle 110 and the first side portion 41A of the retainer 140. For example, the rolling member 21 may be disposed between the receiving portion 112 of the spindle 110 and the receiving portion 116 of the retainer 140. For example, at least a portion of the rolling member 21 may contact the receiving portion 112 of the spindle 110, and at least another portion of the rolling member 21 may contact the receiving portion 116 of the retainer 140.
[0119] Rolling member 21 may include at least one ball member. For example, rolling member 21 may include two or more ball members B1 to B4. For example, rolling member 21 may include a first rolling member 21A and a second rolling member 21B, the first rolling member 21A being disposed between a first receiving portion 112A of the spindle 110 and a first receiving portion 116A of the retainer 140, and the second rolling member 21B being disposed between a second receiving portion 112B of the spindle 110 and a second receiving portion 116B of the retainer 140. For example, the first rolling member 21A may include at least one ball. For example, the first rolling member 21A may include multiple balls B1 and B2. The second rolling member 21B may include at least one ball. For example, the second rolling member 21B may include multiple balls B3 and B4.
[0120] In another embodiment, each of the first rolling member 21A and the second rolling member 21B may include a ball. In another embodiment, each of the first rolling member 21A and the second rolling member 21B may include three or more balls. For example, each of the first rolling member 21A and the second rolling member 21B may include a top ball located at the uppermost side, a bottom ball located at the lowermost side, and at least one intermediate ball located between the top ball and the bottom ball. For example, the diameter of the top ball may be larger than the diameter of the intermediate ball, and the diameter of the bottom ball may be larger than the diameter of the intermediate ball. Alternatively, for example, the diameters of the top ball and the bottom ball may be equal to each other. In another embodiment, the diameters of the top ball, the bottom ball, and the intermediate ball may be equal to each other. For example, each of the first rolling member 21A and the second rolling member 21B may include a first ball (top ball), a second ball (bottom ball), and a third ball (intermediate ball) arranged along the optical axis, wherein the diameter of the first ball may be larger than the diameter of the third ball. Alternatively, the diameter of the second ball may be larger than the diameter of the third ball. For example, the diameters of the first ball and the third ball may be equal to each other. In another embodiment, the diameter of the first sphere may be larger than the diameter of the second sphere. In another embodiment, the diameter of the first sphere may be smaller than the diameter of the second sphere. In yet another embodiment, the diameters of the first sphere, the second sphere, and the third sphere may be equal to each other. For example, each of the diameters of the first and second spheres may be between 0.85 mm and 0.95 mm, and the diameter of the third sphere may be between 0.75 mm and 0.85 mm.
[0121] In another embodiment, each of the first rolling member 21A and the second rolling member 21B may include four balls, wherein the diameter of the top ball and the diameter of the bottom ball may be between 0.85 mm and 0.95 mm, and the diameter of each of the two intermediate balls may be between 0.75 mm and 0.85 mm.
[0122] When viewed from above, the coil 120 and the magnet 130 can be positioned between the first rolling member 21A and the second rolling member 21B. Therefore, when the spool 110 moves along the optical axis, tilting of the spool 110 can be prevented, the rolling member 21 can stably support the spool 110, and the reliability of autofocus can be improved.
[0123] In another embodiment, each of the first rolling member 21A and the second rolling member 21B may be in the form of a shaft or a roller. Another embodiment may include a sliding member (e.g., a shaft or roller) instead of ball members 21A and 21B.
[0124] The camera device 200 may include a magnetic material 82 configured such that an attractive force acts between the magnet 130 and the magnetic material. For example, the attractive force may act between the magnetic material 82 and the magnet 130 in a direction perpendicular to the optical axis (or a second direction). For example, the magnetic material 82 may be disposed on the holder 140. In another embodiment, the magnetic material 82 may be disposed on the housing 210.
[0125] The magnetic material 82 can be a material bonded to the magnet. For example, the magnetic material 82 can be a metallic material. Alternatively, for example, the magnetic material 82 can be a magnetic metallic material. Alternatively, for example, the magnetic material 82 can be a magnet. The magnetic material 82 can be alternatively referred to as a "magnetic yoke" or a "metal plate". The magnetic material 82 can be used to enhance or increase the electromagnetic force between the magnet 130 and the coil 120.
[0126] Since the magnet 130 is disposed on the spool 110 and the magnetic material 82 is disposed on the holder 140, the spool 110 can be pulled toward the holder 140, on which the magnetic material 82 is disposed, by the attraction between the magnetic material 82 and the magnet 130. Due to the attraction between the magnetic material 82 and the magnet 130, the spool 110 and the holder 140 can press against the rolling member 21 and stably support the spool 110. The magnetic material 82 and the magnet 130 can be a "pressing unit" or a "pressing member". When the spool 110 is moved along the optical axis by the pressing unit, contact can be maintained between the spool 110 and the rolling member 21, and between the holder 140 and the rolling member 21. That is, the rolling member 21 can stably support the spool 110 against the holder 140 due to the attraction between the magnet 130 and the magnetic material 82.
[0127] In another embodiment, the magnet 130 may be disposed on the holder 140, and the coil 120 may be disposed on the spool 110. For example, the magnetic material 82 may be disposed on the holder 140 together with the magnet 130. For example, the magnet 130 may be disposed between the magnetic material 82 and the coil 120. In another embodiment, the magnetic material 82 may be disposed on the spool 110 together with the coil 120, while facing the magnet 130 disposed on the holder 140. In addition, the camera device 200 according to another embodiment may also include an energizing member, such as a conductive member, configured to electrically connect the coil 120 disposed on the spool 110 to the second substrate 802 of the circuit board 800.
[0128] Reference Figure 7bThe holder 140 may include a seating portion 45A on which the filter 610 is seated or disposed. The seating portion 45A may be disposed on or formed on the lower surface of the holder 140. For example, the seating portion 45A may be a recessed portion from the lower surface of the holder 140. For example, the seating portion 45A may include a bottom surface 5A and a side surface 5B, the bottom surface 5A having a stepped portion formed from the lower surface of the holder 140 along the optical axis direction, and the side surface 5B connecting the lower surface of the holder 140 to the bottom surface 5A of the seating portion 45A. For example, the opening 30A may be formed through the bottom surface 5A of the seating portion 45A.
[0129] The retainer 140 may include a recessed portion 45B disposed or formed on a corner region of the inner surface of the seating portion 45A. The recessed portion 45B may have a recessed structure in a direction from the optical axis toward the corner region of the inner surface of the seating portion 45A. The recessed portion 45B may prevent adhesives (e.g., UV epoxy resin) configured to attach or bond the filter 610 to the seating portion 45A from overflowing from the seating portion 45A.
[0130] The retainer 140 may include a recess 46 configured to avoid spatial interference with the circuit element 815. For example, the recess 46 may be disposed or formed on the lower surface of the retainer 140. For example, the recess 46 may be recessed from the lower surface of the retainer 140. For example, the recess 46 may correspond to, be opposite to, or overlap with the circuit element 815 in the optical axis direction. For example, the recess 46 may be located between the seat portion 45A and one side of the lower surface of the retainer 140. For example, the recess 46 may include a first recess 46A and a second recess 46B positioned relative to the seat portion 45A or the filter 610. In another embodiment, the recess 46 may include four recesses disposed between the opening 30A and the four sides of the retainer 140.
[0131] The retainer 140 may include a recess 47 corresponding to the protrusion 216 of the sensor base 270. The protrusion 216 of the sensor base 270 and the recess 47 in the retainer 140 can serve as guides to facilitate the assembly of the sensor base 270 and the retainer 140, and can increase the connection area between the sensor base 270 and the retainer 140 to improve the connection force between the sensor base and the retainer.
[0132] For example, the recess 47 may be recessed from the lower surface of the retainer 140. For example, the recess 47 may be provided or formed on a corner or corner region of the lower surface of the retainer 140. The recess 47 in the retainer 140 may have a shape corresponding to the protrusion 216 of the sensor base 270. Additionally, the retainer 140 may include a recess 48 or a hole corresponding to the boss 17 of the sensor base 270. For example, the boss 17 of the sensor base 270 may be inserted into or coupled to the recess 48 in the retainer 140. For example, the recess 48 may be provided or formed on the bottom surface of the recess 47 in the retainer 140. For example, the recess 48 may be recessed from the bottom surface of the recess 47 in the retainer 140.
[0133] In another embodiment, the retainer 140 may include a protrusion protruding from the lower surface of the retainer 140 instead of a recess 47, and the sensor base 270 may include a recess recessing from the upper surface of the sensor base 270 and engaging with the protrusion of the retainer 140 instead of a protrusion 216. Furthermore, in another embodiment, a boss 17 may be formed on the retainer 140, and a recess 48 may be formed in the sensor base 270.
[0134] The camera assembly 200 may include a filter 610 disposed on or coupled to the retainer 140. For example, the filter 610 may be disposed below the retainer 140. The filter 610 may be disposed between the lens module 400 and the image sensor 810. For example, the filter 610 may be coupled to the lower surface of the retainer 140. For example, the filter 610 may be disposed on the mounting portion 45A of the retainer 140.
[0135] Filter 610 can be used to block specific frequency band components of light passing through lens module 400 from incident on image sensor 810. For example, filter 610 can be an infrared cutoff filter. For example, filter 610 can be configured to be parallel to a plane perpendicular to the optical axis OA. Filter 610 can be attached to retainer 140 (or mounting portion 45A) via adhesive (not shown). For example, the edge region of filter 610 can be attached to the bottom surface of mounting portion 45A.
[0136] For example, the adhesive may be epoxy resin, thermosetting adhesive, or UV-curing adhesive. For example, at least a portion of the filter 610 may correspond to, be opposite to, or overlap with the lens module 400 and / or image sensor 810 in the optical axis direction.
[0137] The sensor base 270 may be disposed below the holder 140. The sensor base 270 may be disposed within the housing 210. The sensor base 270 may be disposed below the filter 610. For example, the sensor base 270 may be disposed below the image sensor 810. For example, the sensor base 270 may be disposed below the circuit board 800.
[0138] The sensor base 270 can be coupled to the retainer 140. The sensor base 270 can alternatively be referred to as a "retainer". Additionally, the retainer 140 can be referred to as a "first housing" (or "first retainer"), and the sensor base 270 can be referred to as a "second housing" (or "second retainer"). Furthermore, the retainer 140 and the sensor base 270 may not be referred to separately and may alternatively be referred to by a single term, such as "housing" (or "retainer"). In another embodiment, the sensor base 270 and the retainer 140 can be integrally formed.
[0139] For example, the sensor base 270 may include a protrusion 216 projecting from its upper surface. The protrusion 216 may alternatively be referred to as a "pillar portion." For example, the protrusion 216 may correspond to, be opposite to, or overlap with a recess 47 in the holder 140 in the optical axis direction. At least a portion of the protrusion 216 of the sensor base 270 may be inserted into the recess 47 in the holder 140. For example, at least a portion of the protrusion 216 may be coupled to the recess 47 in the holder 140. For example, at least a portion of the protrusion 216 may be coupled to the recess 47 in the holder 140 via an adhesive.
[0140] For example, the sensor base 270 may include a body 270A and a protrusion 216 projecting from the upper surface of the body 270A. For example, the body 270A may have a shape corresponding to the first substrate 801 of the circuit board 800. For example, the body 270A may have a polyhedral shape, such as a hexahedral shape. For example, the protrusion 216 may be disposed on a corner region of the upper surface of the body 270A. For example, the protrusion 216 may include four protrusions 216A to 216D disposed on four corner regions of the upper surface of the body 270A. Additionally, for example, the retainer 140 may include four recesses 47 corresponding to the four protrusions 216A to 216D. In another embodiment, the housing 210 may include at least one protrusion disposed on at least one corner region of the four corner regions of the upper surface of the body 270A, and the retainer 140 may include at least one recess 48 corresponding to at least one protrusion of the housing 210.
[0141] The sensor base 270 or body 270A may include side portions 51A to 51D, which correspond to, are opposite to, or overlap with the side portions 41A to 41D of the holder 140. The sensor base 270 may include corners disposed between the side portions 51A to 51D. For example, the sensor base 270 may include a first corner to a fourth corner.
[0142] The camera device 200 may include a gyroscope sensor (not shown) disposed on a circuit board 800. For example, the gyroscope sensor may be disposed on a first substrate 801 of the circuit board 800. For example, the gyroscope sensor may be disposed on the lower surface of the first substrate 801, coupled to, or fixed to the lower surface of the first substrate 801. For example, the gyroscope sensor may output rotational angular velocity information caused by the motion of the camera device 200. For example, the gyroscope sensor may be implemented as a 2-axis or 3-axis gyroscope sensor or an angular velocity sensor. For example, the gyroscope sensor may be electrically connected to or conductively connected to the first substrate 801.
[0143] In another embodiment, the sensor base 270 may include a receiving portion configured to allow a gyroscope sensor to be disposed therein, or to avoid spatial interference with the gyroscope sensor. For example, the receiving portion may be a through-hole formed along the optical axis through the sensor base 270, or a recessed portion from the upper surface of the sensor base 270 or the upper surface of the body 270A. In this case, the receiving portion may include an opening leading to the outer surface of the sensor base 270.
[0144] The sensor base 270 may include a receiving portion 255 in which the controller 830 is disposed, or the controller 830 is received within the receiving portion 255. The receiving portion 255 may be a recess that extends from the upper surface of the sensor base 270 or the upper surface of the body 270A. In another embodiment, the receiving portion 255 may be a through hole formed along the optical axis through the sensor base 270 or the body 270A.
[0145] The sensor base 270 may include a mounting portion 274 configured to allow a coil 230 to be disposed thereon. The mounting portion 274 may be disposed on or formed on the upper surface of the sensor base 270. For example, the mounting portion 274 may be a recessed portion from the upper surface of the sensor base 270. For example, the sensor base 270 may include a first mounting portion 274A and a second mounting portion 274B, the first mounting portion 274A being configured to allow a first coil unit 230A to be disposed on or mounted thereon, and the second mounting portion 274B being configured to allow a second coil unit 230B to be disposed on or mounted thereon.
[0146] For example, the first seating portion 274A may be formed adjacent to or abutting any of the protrusions 216A to 216D (e.g., 216C) of the sensor base 270. For example, the first seating portion 274A may be a recess formed in the upper surface of the sensor base 270 adjacent to the third protrusion 216C of the sensor base 270. For example, the first seating portion 274A may include an opening leading to the outer surface of a side portion (e.g., 51B and 51D) adjacent to the third protrusion 216C of the sensor base 270. In another embodiment, the first seating portion 274A may be spaced apart from the outer surface of the side portions (e.g., 51B and 51D) of the sensor base 270 and may not include an opening leading to the outer surface of the side portions 51B and 51D.
[0147] For example, the second seating portion 274B may be formed adjacent to or abutting against another of the protrusions 216A to 216D of the sensor base 270 (e.g., 216D). For example, the second seating portion 274B may be a recess formed in the upper surface of the sensor base 270 adjacent to the fourth protrusion 216D of the sensor base 270. For example, the second seating portion 274B may include an opening leading to the outer surface of a side portion (e.g., 51B and 51C) adjacent to the fourth protrusion 216D of the sensor base 270. In another embodiment, the second seating portion 274B may be spaced apart from the outer surface of the side portions (e.g., 51B and 51C) of the sensor base 270 and may not include an opening leading to the outer surface of the side portions 51B and 51C.
[0148] In another embodiment, the mounting portion 274 of the sensor base 270 can be formed at a position corresponding to the location where the coil 230 is disposed. In another embodiment, each of the mounting portions 274A and 274B can be in the form of a through hole. For example, at least one of the first mounting portion 274A and the second mounting portion 274B can be a hole or through hole formed through the sensor base 270 along the optical axis direction. In this case, a portion of the sensor base 270 may not be inserted between the coil 230 and the magnet 310, which can increase the electromagnetic force between the magnet 310 and the coil 230. In addition, a portion of the sensor base 270 may not be inserted between the position sensor 240 and the magnet 310, which can increase the output of the position sensor 240 and improve the sensitivity of the position sensor 240. Furthermore, since a portion of the sensor base 270 is not inserted between the position sensor 240 and the magnet 310, the height of the camera device can be reduced. In another embodiment, each of the seating portions 274A and 274B may be an avoidance portion that avoids spatial interference with the entire coil 230.
[0149] The sensor base 270 may include a recess 29 in which at least a portion of the tilting guide unit 60 (e.g., a boss 65) is disposed or received. The recess 29 may be formed in the lower surface of the sensor base 270. For example, the recess 29 may be recessed from the lower surface of the sensor base 270. The number of recesses 29 may be equal to the number of bosses 65 of the tilting guide unit 60.
[0150] For example, recess 29 may include two recesses 29A and 29B spaced apart from each other. For example, the two recesses 29A and 29B may be configured to be spaced apart from each other in the first axial direction (see...). Figure 13a An extension 217 of the sensor base 270 may be disposed between two recesses 29A and 29B of the sensor base 270.
[0151] The recess 29 may contact the boss 65 of the tilting guide unit 60 at at least one point. For example, the recess 29 may include a bottom surface and at least one side surface connected to the bottom surface. The at least one side surface may be a tilted surface. For example, the recess 29 may include a bottom surface and a plurality of tilted surfaces. The tilted surfaces of the recess 29 may have the same shape. In another embodiment, at least one of the tilted surfaces of the recess 29 may have a different shape than the other tilted surfaces.
[0152] Reference Figure 7a The protrusion 216 of the sensor base 270 may have a recess 212A, into which at least a portion of the first substrate 801 of the circuit board 800 is inserted or disposed. For example, a corner of the first substrate 801 may be inserted into or connected to the recess 212A in the protrusion 216 of the sensor base 270. For example, the recess 212A may be formed in the side surface of the protrusion 216 opposite to the corner of the circuit board 800. In addition, at least one corner of the circuit board 800 may have a recess 83 configured to be inserted into or connected to the recess 212A in the protrusion 216. The recess 212A of the protrusion 216 of the sensor base 270 can be used as a connection guide for connecting the first substrate 801 and the sensor base 270, and can be used to suppress the rotation of the first substrate 801 and / or separation from the sensor base 270.
[0153] The sensor base 270 may include an extension 217 extending from the lower portion or lower surface of the sensor base 270. The extension 217 may protrude from the lower surface of the sensor base 270. The extension 217 may protrude from the lower surface of the sensor base 270 in a downward direction.

[0154] The extension portion 217 may have a cylindrical, tubular, or polyhedral shape. The lower surface of the extension portion 217 may include a flat surface for attachment to the elastic member 30. The extension portion 217 and the sensor base 270 may be integrally formed with each other. In another embodiment, the extension portion 217 may have a structure configured to attach to the sensor base 270.
[0155] The sensor base 270 may include an adhesive portion 219 disposed on the lower surface of the sensor base 270. The adhesive portion 219 may be disposed around the extension portion 217. The adhesive portion 219 may be disposed around the upper end of the extension portion 217. The adhesive portion 219 may be disposed corresponding to, opposite to, or overlapping with the opening 60A in the tilt guide unit 60. Foreign matter or contaminants may adhere to the adhesive portion 219. The adhesive portion 219 may be formed of an adhesive material to which foreign matter or contaminants are bonded or adhered. Foreign matter or contaminants introduced through the opening 60A in the tilt guide unit 60 may adhere to the adhesive portion 219. Therefore, the adhesive portion 219 can be used to prevent foreign matter or contaminants from being introduced into the image sensor 810. The adhesive portion 219 may include a avoidance portion configured to avoid spatial interference with the recess 29.
[0156] In another embodiment, a recess can be formed in the lower surface of the sensor base 270 where the adhesive portion 219 is provided, and the adhesive portion 219 can be formed by providing adhesive material in the recess of the sensor base 270. Here, the recess in the sensor base 270 can facilitate the application of adhesive material.

For example, a rigid printed circuit board may include a plurality of conductive layers (or circuit patterns) spaced apart from each other along the optical axis and an insulating layer disposed between two adjacent conductive layers. For example, a flexible circuit board may include a conductive layer (or circuit pattern), a first insulating layer disposed on the conductive layer, and a second insulating layer disposed below the conductive layer. In another embodiment, the flexible circuit board may include a first conductive layer, a second conductive layer, a first insulating layer disposed between the first and second conductive layers, a second insulating layer disposed on the first conductive layer, and a third insulating layer disposed below the second conductive layer.
[0163] Image sensor 810 may be disposed on sensor base 270. Image sensor 810 may be disposed on circuit board 800. Image sensor 810 may be disposed on first substrate 801. Image sensor 810 may be configured to correspond to, be opposite to, or overlap with lens module 400 and / or filter 610 in the optical axis direction. For example, image sensor 810 may be disposed on the upper surface of circuit board 800. For example, image sensor 810 may be disposed on the upper surface of first substrate 801.
[0164] Image sensor 810 may include a sensor surface configured to detect light. For example, the sensor surface may include an image capture region. Here, the image capture region may alternatively be referred to as an effective region, a light receiving region, or an active region. For example, the image capture region may include a plurality of pixels thereon that form an image. The image capture region may correspond to, be opposite to, or overlap with lens module 400 and / or filter 610 in the optical axis direction.
[0165] Image sensor 810 may be conductively connected to or electrically connected to first substrate 801. For example, image sensor 810 may be conductively connected to first substrate 801 via a conductive member, such as a wire (not shown). For example, the first substrate 801 of circuit board 800 may include at least one pad or terminal (not shown) conductively connected to a wire that is conductively connected to image sensor 810. For example, the pad or terminal conductively connected to the wire may be disposed on the upper surface of first substrate 801.
[0166] The camera device 200 may include circuit elements 815 disposed on the first substrate 801. For example, the circuit elements 815 may include at least one of passive elements (e.g., capacitors or resistors), active elements (e.g., sensors, memory, or driver ICs), or circuit patterns. For example, to avoid spatial interference with the image sensor 810, the circuit elements 815 may be disposed between the image sensor 810 and the edge (e.g., side) of the first substrate 801.
[0167] The camera device 200 may include a controller 830 disposed on a circuit board 800. For example, the controller 830 may be a driver IC. For example, the controller 830 may be disposed on a first substrate 801. For example, the controller 830 may be disposed below the first substrate 801. For example, the controller 830 may be disposed on the lower surface of the first substrate 801, coupled to, or fixed to the lower surface of the first substrate 801. For example, the controller 830 may be electrically connected to or electrically connected to the first substrate 801.
[0168] For example, controller 830 may be electrically connected to or electrically connected to coil 120, and may supply a drive signal to the first coil 120. Controller 830 may be electrically connected to or electrically connected to coil units 230A and 230B of coil 230, may supply a first drive signal to the first coil unit 230A, and may supply a second drive signal to the second coil unit 230B.
[0169] The controller 830 may be electrically connected to or electrically connected to the position sensor 170. Additionally, the controller 830 may be electrically connected to or electrically connected to the position sensor 240. For example, the controller 830 may receive an output signal from the position sensor 170 and may use the output signal from the position sensor 170 to control a drive signal (e.g., drive current) supplied to the coil 120.
[0170] For example, controller 830 can receive an output signal from position sensor 240 and use the output signal from position sensor 240 to control a drive signal (e.g., drive current) supplied to coil 230. For example, controller 830 can receive an output signal from first sensor 240A and use the output signal from first sensor 240A to control a first drive signal (e.g., first drive current) supplied to first coil unit 230A. Additionally, controller 830 can receive an output signal from second sensor 240B and use the output signal from second sensor 240B to control a second drive signal (e.g., second drive current) supplied to second coil unit 230B.
[0171] Coils 120 and 230 may be disposed on, connected to, or fixed to circuit board 800. For example, coil 120 may be electrically connected to or connected to circuit board 800 (e.g., second substrate 802) via conductive adhesive or solder. For example, coil 230 may be electrically connected to or connected to circuit board 800 (e.g., first substrate 801) via conductive adhesive or solder.
[0172] The first coil unit 230A and the second coil unit 230B can be disposed on or connected to the first substrate 801, and can be electrically connected to or conductively connected to the first substrate 801. (Refer to...) Figure 7b For example, the first coil unit 230A and the second coil unit 230B may be disposed on the lower surface of the first substrate 801, connected to or fixed to the lower surface of the first substrate 801. For example, the first coil unit 230A and the second coil unit 230B may be disposed between the first substrate 801 and the sensor base 270.
[0173] For example, the first coil unit 230A and the second coil unit 230B can be arranged adjacent to two adjacent corners of the four corners of the first substrate 801. For example, for diagonal drive, the first coil unit 230A can be arranged adjacent to one corner of the first substrate 801 corresponding to the protrusion 216C of the sensor base 270 (or one corner of the sensor base 270), and the second coil unit 230B can be arranged adjacent to another corner of the first substrate 801 corresponding to the protrusion 216D of the sensor base 270 (or another corner of the sensor base 270). For example, the first coil unit 230A can be arranged adjacent to the protrusion 216C of the sensor base 270, and the second coil unit 230B can be arranged adjacent to the protrusion 216D of the sensor base 270.
[0174] In another embodiment, the first coil unit 230A and the second coil unit 230B may be disposed adjacent to two adjacent sides of the four sides of the first substrate 801.
[0175] The coil 120 can move the AF moving unit (e.g., a spool) along the optical axis direction through interaction with the magnet 130. The coil 120 can be disposed on the holder 140. The coil 120 can be disposed on the second substrate 902.
[0176] The coil 120 can be configured to correspond to, be opposite to, or overlap with the magnet 130 in a direction perpendicular to the optical axis. For example, the coil 120 can be disposed on the holder 140 so as to correspond to, be opposite to, or overlap with the magnet 130 in a second direction (e.g., the X-axis direction) or in a direction from the first side portion 41A to the second side portion 41B of the holder 140. For example, the coil 120 can be disposed on the first side portion 41A of the holder 140. The coil 120 can also be disposed in the seating portion 142A of the holder 140.
[0177] For example, coil 120 may include a hollow portion or a hole. For example, coil 120 may have an annular shape or a closed curved shape. For example, coil 120 may have an annular shape wound around a straight line that is an axis, perpendicular to the optical axis OA, and perpendicular to the outer surface of the first side portion 41A of retainer 140. For example, coil 120 may have an annular shape configured such that its length in the transverse direction (or a third direction) is greater than its length in the longitudinal direction (or optical axis direction).
[0178] A drive signal can be applied to coil 120 to generate an electromagnetic force through electromagnetic interaction with magnet 130. For example, a drive signal from circuit board 800 or controller 830 can be applied to coil 120. The drive signal supplied to coil 120 can be DC and can be in the form of voltage or current. Alternatively, in another embodiment, for example, the drive signal supplied to coil 120 can include at least one of DC signal or AC signal.
[0179] The coil 120, to which a drive signal has been supplied, can electromagnetically interact with the magnet 130 disposed on the spool 110, and the AF moving unit can be moved in a first direction by the electromagnetic force generated by the electromagnetic interaction between the coil 120 and the magnet 130. The magnitude and / or direction of the drive signal (e.g., drive current) can be adjusted by the controller 830, thereby controlling the movement of the AF moving unit in the first direction and thus enabling the autofocus function to be performed.
[0180] For AF feedback drive, camera device 200 may include position sensor 170. Position sensor 170 can detect the position or displacement of spool 110 in the optical axis direction. For example, position sensor 170 can detect magnet 130 disposed on spool 110. In another embodiment, a sensing magnet separate from magnet 130 and opposite to position sensor 170 may be disposed on spool, and position sensor 170 can detect sensing magnet or the magnetic field of sensing magnet to detect displacement of spool.
[0181] For example, position sensor 170 may be disposed on holder 140. For example, position sensor 170 may be disposed on the first side portion 41A of holder 140. For example, position sensor 170 may be disposed in the seating portion 142A of holder 140. For example, position sensor 170 may be disposed in the hollow portion of coil 120. In another embodiment, position sensor 170 may be disposed outside the hollow portion of coil 120.
[0182] For example, position sensor 170 can be coupled to circuit board 800. For example, position sensor 170 can be coupled to circuit board 800 via conductive adhesive or solder. For example, position sensor 170 can be electrically connected to or connected to second substrate 802 via conductive adhesive or solder.
[0183] For example, the position sensor 170 may be disposed on the first surface of the second substrate 802, coupled to or fixed to the first surface of the second substrate 802. For example, the position sensor 170 may correspond to, be opposite to or overlap with the magnet 130 in a direction perpendicular to the optical axis or in a second direction.
[0184] The position sensor 170 can detect the displacement of the spool 110 in the optical axis direction. For example, the position sensor 170 can detect the magnetic field or magnetic field strength of the magnet 130 mounted on the spool 110 based on the movement of the spool 110, and can output an output signal.
[0185] For example, position sensor 170 may be a Hall sensor. In this case, position sensor 170 may include two input terminals and two output terminals, applying drive signals to the two input terminals and outputting output signals from the two output terminals. Circuit board 800 may be electrically connected to the two input terminals and the two output terminals of position sensor 170. Circuit board 800 or controller 830 may supply drive signals to the two input terminals of position sensor 170, and output signals from the two output terminals of position sensor 170 may be transmitted to circuit board 800 or controller 830.
[0186] In another embodiment, the position sensor 170 may be implemented as a driver IC that includes a Hall sensor. For example, when the position sensor 170 is a driver IC that includes a Hall sensor, the position sensor 170 can transmit data to and receive data from the outside via data communication using a protocol such as I2C communication.
[0187] For example, when position sensor 170 is a driver IC including a Hall sensor, position sensor 170 may include a first terminal and a second terminal for inputting power or a drive signal, a third terminal for a clock signal, a fourth terminal for a data signal, and a fifth and a sixth terminal configured to supply a drive signal to coil 120. The first to sixth terminals of position sensor 170 may be electrically connected to or conductively connected to circuit board 800.
[0188] The coil 230 can tilt the OIS moving unit about the first axis or the second axis, or rotate the OIS moving unit by a predetermined angle due to its interaction with the magnet 310 disposed on the housing 210, which is a fixed unit.
[0189] The coil 230 may be opposite, correspond to, or overlap with the magnet 310 in the optical axis direction. The coil 230 may include a first coil unit 230A and a second coil unit 230B. The first coil unit 230A corresponds to, is opposite to, or overlaps with the first magnet unit 310A in the optical axis direction, and the second coil unit 230B corresponds to, is opposite to, or overlaps with the second magnet unit 310B in the optical axis direction. For example, the coil 230 may not overlap with the magnet 310 in a direction perpendicular to the optical axis.
[0190] For example, coil 230 can be configured to be lower than coil 120. For example, first coil unit 230A can be disposed in first mounting portion 274A of sensor base 270, and second coil unit 230B can be disposed in second mounting portion 274B of sensor base 270.
[0191] For example, each of the first coil unit 230A and the second coil unit 230B may include a hollow portion or a hole. For example, each of the first coil unit 230A and the second coil unit 230B may have an annular shape or a closed curved shape. For example, each of the first coil unit 230A and the second coil unit 230B may have an annular shape that is wound around a straight line that is parallel to the optical axis OA and perpendicular to the upper surface of the sensor base 270 or the upper surface of the body 270A.
[0192] For example, refer to Figure 13a The first coil unit 230A may have an annular shape configured such that its length in the transverse direction (or in the direction parallel to the second axis) is greater than its length in the longitudinal direction (or in the direction parallel to the first axis). For example, the second coil unit 230B may have an annular shape configured such that its length in the longitudinal direction (or in the direction parallel to the first axis) is greater than its length in the transverse direction (or in the direction parallel to the second axis).
[0193] For OIS feedback drive, camera device 200 may include position sensor 240. Position sensor 240 can detect displacement or angular displacement of OIS moving unit 100 caused by tilting or rotating OIS moving unit. Position sensor 240 can detect magnetic field of magnet 310.
[0194] For example, the position sensor 240 may include a first sensor 240A and a second sensor 240B. For example, at least a portion of the first sensor 240A may correspond to, be opposite to, or overlap with the first magnet unit 310A in the optical axis direction. For example, the center of the first sensor 240A may overlap with the first magnet unit 310A in the optical axis direction. For example, the first sensor 240A may detect the first magnet unit 310A (or the magnetic field of the first magnet unit 310A). For example, the first sensor 240A may detect the tilt angle of the OIS movement unit 100 relative to the second axis. In another embodiment, the first sensor 240A may not overlap with the first magnet unit 310A and the second magnet unit 310B in the optical axis direction.
[0195] At least a portion of the second sensor 240B may correspond to, be opposite to, or overlap with the second magnet unit 310B in the optical axis direction. For example, the center of the second sensor 240B may overlap with the second magnet unit 310B in the optical axis direction. For example, the second sensor 240B may detect the second magnet unit 310B (or the magnetic field of the second magnet unit 310B). For example, the second sensor 240B may detect the tilt angle of the OIS moving unit 100 relative to the first axis. In another embodiment, the second sensor 240B may not overlap with the second magnet unit 310B in the optical axis direction.
[0196] For example, the first sensor 240A and the second sensor 240B can be disposed on the first substrate 801 of the circuit board 800, connected to or fixed to the first substrate 801 of the circuit board 800. For example, the first sensor 240A and the second sensor 240B can be electrically connected to or electrically connected to the first substrate 801.
[0197] For example, the first sensor 240A may be disposed in the hollow portion (or hole) of the first coil unit 230A, and the second sensor 240B may be disposed in the hollow portion (or hole) of the second coil unit 230B. In another embodiment, the first sensor 240A may be disposed outside the hollow portion (or hole) of the first coil unit 230A, and the second sensor 240B may be disposed outside the hollow portion (or hole) of the second coil unit 230B.
[0198] For example, each of the first sensor 240A and the second sensor 240B may be a Hall sensor including a first input terminal and a second input terminal, as well as a first output terminal and a second output terminal. For example, the first input terminal and the second input terminal, as well as the first output terminal and the second output terminal of the first sensor 240A may be electrically connected to or connected to the first substrate 801, and the first input terminal and the second input terminal, as well as the first output terminal and the second output terminal of the second sensor 240B may be electrically connected to or connected to the first substrate 801.
[0199] For example, the first substrate 801 or the controller 830 can supply or apply a first drive signal to the first input terminal and the second input terminal of the first sensor 240A. The first sensor 240A can output a first output signal, and the first output signal can be transmitted to the first substrate 801 or the controller 830. The first output signal can be output to the first output terminal and the second output terminal of the first sensor 240A.
[0200] For example, the first substrate 801 or the controller 830 can supply or apply a second drive signal to the first input terminal and the second input terminal of the second sensor 240B. The second sensor 240B can output a second output signal, and the second output signal can be transmitted to the first substrate 801 or the controller 830. The second output signal can be output to the first output terminal and the second output terminal of the second sensor 240B.
[0201] The controller 830 can use the first output signal from the first sensor 240A and the output signal from the second sensor 240B to control the first drive signal supplied to the first coil unit 230A and the second drive signal supplied to the second coil unit 230B.
[0202] In another embodiment, each of the first sensor 240A and the second sensor 240B may be a driver IC that includes a Hall sensor. The description of the embodiment in which the position sensor 170 is a driver IC that includes a Hall sensor can be applied or similarly applied to embodiments in which each of the first sensor 240A and the second sensor 240B is a driver IC that includes a Hall sensor.
[0203] The camera device 200 may include a magnetic material 82 disposed opposite to at least one of the coil 120 or the magnet 130. For example, the magnetic material 82 may be disposed on the holder 140 or on the second substrate 802 of the circuit board 800. For example, the magnetic material 82 may be disposed corresponding to, opposite to, or overlapping the magnet 130 in a second direction. Additionally, for example, the magnetic material 82 may be disposed corresponding to, opposite to, or overlapping the coil 120 in a second direction. For example, the coil 120 may be disposed on a first surface of the second substrate 802 facing the magnet 130, and the magnetic material 82 may be disposed on a second surface of the second substrate 802 opposite to the first surface of the second substrate 802. The magnetic material 82 may be bonded, attached, or fixed to the second substrate 802 via an adhesive.
[0204] The camera device 200 may include a heat dissipation member (not shown) connected to at least one of the circuit board 800 or the sensor base 270. For example, the heat dissipation member may be disposed below the circuit board 800. For example, the heat dissipation member 280 may be disposed between the circuit board 800 and the sensor base 270. The heat dissipation member may be a plate-shaped member with a predetermined thickness and rigidity. In addition, the heat dissipation member can dissipate heat generated from the heat source of the circuit board 800 to the outside and can improve heat dissipation efficiency. For example, the heat dissipation member may be a metal material or a metal plate.
[0205] Reference Figure 10a and Figure 10b The housing 210 may include a cavity configured to receive the OIS moving unit 100. For example, the housing 210 may have a shape corresponding to the OIS moving unit 100, such as the holder 140 or the sensor base 270, such as, but not limited to, a polygonal shape (e.g., a quadrilateral or octagonal shape) or a circular shape (or an elliptical shape), and may have various shapes. The housing 210 may alternatively be referred to as a “base” or a “frame”.
[0206] The housing 210 may include a plurality of side portions 71A to 71D corresponding to the side portions 41A to 41D of the retainer 140 or the side portions 51A to 51D of the sensor base 270. The housing 210 may include a corner located between two adjacent side portions.
[0207] Additionally, the housing 210 may include a lower portion 42 (or lower plate) located below the side portions 71A to 71D. The lower portion 42 may be connected to the lower side of each of the side portions 71A to 71D. For example, the lower portion 42 may be alternatively referred to as a "bottom portion," "bottom surface," or "body." For example, the side portions 71A to 71D may project upward from the lower portion 42.
[0208] The housing 210 has a first side portion 71A that corresponds to, is opposite to, or overlaps with the first side portion 41A of the retainer 140, a second side portion 71B that corresponds to, is opposite to, or overlaps with the second side portion 41B of the retainer 140, a third side portion 71C that corresponds to, is opposite to, or overlaps with the third side portion 41C of the retainer 140, and a fourth side portion 71D that corresponds to, is opposite to, or overlaps with the fourth side portion 41D of the retainer 140.
[0209] The first side portion 71A (or the first side surface or the first outer surface) of the housing 210 may be positioned relative to the second side portion 71B (or the second side surface or the second outer surface) of the housing 210, and the third side portion 71C (or the third side surface or the third outer surface) of the housing 210 may be positioned relative to the fourth side portion 71D (or the fourth side surface or the fourth outer surface) of the housing 210. For example, each of the first side portions 71A to the fourth side portions 71D of the housing 210 may be arranged parallel to a corresponding side plate in the side plate 302 of the cover member 300.
[0210] The housing 210 may include a stepped portion 411 disposed on the lower portion of at least one of the side portions 71A to 71D. For example, the stepped portion 411 may protrude from the outer surface of each of the side portions 71A to 71D of the housing 210 in a direction perpendicular to the optical axis. For example, the stepped portion 411 may be opposite to or overlap with the side plate 302 of the cover member 300 in the optical axis direction. For example, the stepped portion 411 may be attached to the side plate 302 of the cover member 300 via an adhesive.
[0211] The housing 210 may include seating portions 141A and 141B on which the magnet 310 is disposed. For example, each of the seating portions 141A and 141B may be a recess formed in the lower portion 42 of the housing 210. In another embodiment, each of the seating portions 141A and 141B may be a through hole formed through the lower portion 42 of the housing 210.
[0212] The housing 210 may include a first mounting portion 141A on which a first magnet unit 310A is disposed, and a second mounting portion 141B on which a second magnet unit 310B is disposed. For example, the first mounting portion 141A may be disposed or formed in a first region of the lower portion 42 of the housing 210, which is adjacent to one of the four corners of the housing 210. For example, one corner of the housing 210 may be a corner corresponding to or adjacent to the protrusion 216C of the sensor base 270.
[0213] For example, the second seating portion 141B may be disposed or formed in a second region of the lower portion 42 of the housing 210, which is adjacent to another corner of the four corners of the housing 210. For example, the other corner of the housing 210 may be a corner corresponding to or adjacent to the protrusion 216D of the sensor base 270.
[0214] In another embodiment, the first and second seating portions may be positioned at locations corresponding to the locations where coil units 230A and 230B and magnet units 310A and 310B are disposed. For example, in another embodiment, the first seating portion may be formed adjacent to a first side portion (or a second side portion) of the housing 210, and the second seating portion may be formed adjacent to a third side portion (or a fourth side portion) of the housing 210.
[0215] The magnet 310 may be disposed on or attached to the housing 210. For example, the magnet 310 may include a first magnet unit 310A and a second magnet unit 310B disposed on the lower portion 42 of the housing 210. For example, the magnet 310 may be disposed below the coil 230.
[0216] For example, the first magnet unit 310A can be configured to correspond to, be opposite to, or overlap with the first coil unit 230A in the optical axis direction. The second magnet unit 310B can be configured to correspond to, be opposite to, or overlap with the second coil unit 230B in the optical axis direction.
[0217] For example, the first magnet unit 310A and the second magnet unit 310B can be configured to be misaligned with each other in the direction of the first axis (or parallel to the first axis) or the direction of the second axis (or parallel to the second axis). For example, when viewed from above or along the optical axis, the first magnet unit 310A and the second magnet unit 310B can be configured on the housing 210 to not overlap each other in the direction parallel to the first axis or parallel to the second axis. For example, the first magnet unit 310A and the second magnet unit 310B can be configured on the lower portion 42 of the housing 210 to not overlap each other in the direction parallel to the first axis or parallel to the second axis.
[0218] In another embodiment, the first magnet unit and the second magnet unit may be configured to be misaligned with each other in a first horizontal direction (or X-axis direction) or a second horizontal direction (or Y-axis direction). For example, in another embodiment, when viewed from above, the first magnet unit may be configured to overlap with the first horizontal axis (or X-axis), and the second magnet unit may be configured to overlap with the second horizontal axis (or X-axis).
[0219] Each of the first magnet unit 310A and the second magnet unit 310B can be a bipolar magnet comprising an N pole and a S pole. For example, each of the first magnet unit 310A and the second magnet unit 310B can be a magnet having N poles and S poles separated or arranged along the optical axis. For example, the N pole (or S pole) of each of the first magnet unit 310A and the second magnet unit 310B can be located above its S pole (or N pole).
[0220] For example, the first surface of magnet 310 facing or opposite coil 230 in the optical axis direction may have an S pole (or N pole). The second surface of magnet 310 opposite to the first surface may have an N pole (or S pole).
[0221] exist Figure 2a and Figure 2b In one embodiment, coil 230 and magnet 310 face each other in the optical axis direction. However, in another embodiment, coil 230 and magnet 310 may be arranged to face each other in a direction perpendicular to the optical axis direction (e.g., a second or third direction). In this case, magnet units 310A and 310B may be disposed on two adjacent side portions 71A to 71D of the housing 210, and coil units 230A and 230B may be disposed on a moving unit (e.g., holder 140) facing magnet units 310A and 310B in a direction perpendicular to the optical axis. In this case, circuit board 800 may include an additional substrate (or extension area) connected to the first substrate 801 and configured to allow coil units 230A and 230B to be disposed thereon. In another embodiment, the position sensor 240 may be disposed together with the coil 230 on two side portions of the housing 210, and may be disposed on or connected to an additional substrate (or extension area) of the circuit board 800. In another embodiment, magnet units 310A and 310B may be disposed on two adjacent corners of the housing 210.
[0222] Reference Figure 10a and Figure 13a The camera device 200 may include a yoke 380 disposed on a magnet 310. The yoke 380 may reduce or suppress leakage flux from the magnet 310, increase the electromagnetic force between the magnet 310 and the coil 230, and enhance the driving force for OIS operation. The yoke 380 may be made of a material adhered to the magnet. For example, the yoke 380 may be made of a metallic material. Alternatively, for example, the yoke 380 may be made of a magnetic metallic material. Alternatively, for example, the yoke 380 may be a magnetic material, such as a magnet.
[0223] A yoke 380 may be disposed on the housing 210. For example, the yoke 380 may be disposed between the housing 210 and the magnet 310. For example, the yoke 380 may be disposed in the seating portions 141A and 141B of the housing 210. For example, the yoke 380 may face the magnet 310 or the coil 230. For example, the yoke 380 may be disposed on a second surface (e.g., the lower surface) of the magnet 310, which is opposite to the first surface (e.g., the upper surface) of the magnet 310 facing the coil 230. The yoke 380 may contact or be attached to the magnet 310. For example, the yoke 380 may be adhered to the magnet 310.
[0224] For example, the yoke 380 can be coupled to the housing 210 by insert injection molding. When the yoke 380 and the housing 210 are coupled to each other by insert injection molding, at least a portion of the yoke 380 can be located in the housing 210, and at least another portion of the yoke 380 can be exposed from the housing 210 and can be coupled or attached to the magnet 310.
[0225] In another embodiment, the yoke 380 can be disposed in the seating portions 141A and 141B of the housing 210 by an adhesive. The yoke 380 may include a first yoke 380A disposed on the first magnet unit 310A and a second yoke 380B disposed on the second magnet unit 310B. For example, the first yoke 380A may be disposed in the first seating portion 141A of the housing 210, and the second yoke 380B may be disposed in the second seating portion 141B of the housing 210. Since the magnet 310 can be adhered to the yoke 380, the assemblability between the magnet 310 and the housing 210 can be improved or the assembly between the magnet 310 and the housing 210 can be facilitated when the magnet 310 is assembled to the housing 210.
[0226] In another embodiment, each of the first magnet unit 310A and the second magnet unit 310B may be a magnet having an N pole and a S pole separated or arranged in a direction perpendicular to the optical axis. In another embodiment, each of the first magnet unit 310A and the second magnet unit 310B may be a magnet including two N poles and two S poles. Electromagnetic forces can be generated between the first magnet unit 310A and the second magnet unit 310B and the first coil unit 230A and the second coil unit 230B, and the generated electromagnetic forces can cause the first axis or the second axis of the OIS moving unit to tilt.
[0227] In another embodiment, Figure 6The positions of the magnet 310 and the coil 230 can be interchanged. For example, the magnet 310 can be disposed on the moving unit 100 (e.g., the sensor base 270), and the coil 230 can be disposed on the fixed unit (e.g., the housing 210). In this case, Figure 13aA magnetic yoke may be disposed on the sensor base 270. For example, the magnetic yoke may be disposed on the upper surface of the magnet 310. A camera device according to another embodiment may include a circuit board (referred to as a "second circuit board") arranged separately from the circuit board 800 (referred to as the "first circuit board") and disposed on a fixing unit (e.g., housing 210). A coil 230 may be disposed on or connected to the second circuit board. The coil 230 may be electrically connected to or conductively connected to the second circuit board. For example, the second circuit board may be disposed below the housing 210. The coil 230 may be disposed on a sitting portion 141 of the housing 140, wherein the sitting portion 141 may be a through-hole formed through the lower portion 42 of the housing 140. A position sensor 240 may be disposed on or connected to the second circuit board. For example, a first sensor 240A may be disposed in the hollow portion of the first coil unit 230A, and a second sensor 240B may be disposed in the hollow portion of the second coil unit 230B. The position sensor 240 may be electrically connected to or conductively connected to the second circuit board. According to another embodiment, the camera device may include a controller (referred to as a "second controller") separate from the controller 830 (referred to as a "first controller"). The second controller may be disposed on a second circuit board. The second controller may be electrically connected to or electrically coupled to the second circuit board. For example, the second controller may be a driver IC. For example, the second controller may be disposed on a first surface of the second circuit board, coupled to, or fixed to the first surface of the second circuit board. The first surface of the second circuit board may be a surface facing the magnet 310 or the OIS movement unit, such as a lens module. A second coil 230 may be disposed on the first surface of the second circuit board. The second controller may be electrically connected to or electrically coupled to the coil 230. A drive signal may be supplied to the coil 230. For example, the second controller may be electrically connected to coil units 230A and 230B, may supply a first drive signal to the first coil unit 230A, and may supply a second drive signal to the second coil unit 230B. The second controller may be electrically connected to or electrically coupled to a position sensor 240. For example, the second controller may supply power or a drive signal to the position sensor 240. For example, the second controller may supply power or a drive signal to each of the first sensor 240A and the second sensor 240B. The controller 830 can receive an output signal from the position sensor 240 and can use the output signal from the position sensor 240 to control a drive signal (e.g., drive current) supplied to the coil 230. For example, the second controller can receive an output signal from the first sensor 240A and can use the output signal from the first sensor 240A to control a first drive signal (e.g., a first drive current) supplied to the first coil unit 230A.Additionally, the second controller can receive the output signal from the second sensor 240B and can use the output signal from the second sensor 240B to control the second drive signal (e.g., a second drive current) supplied to the second coil unit 230B. The second circuit board may include terminal units. The terminal units may include multiple terminals. For example, multiple terminals of the second circuit board may be exposed from the side plate 302 of the cover member 300. At least one of the multiple terminals may be electrically connected to or electrically connected to the second controller.
[0228] Additionally, according to another embodiment, the second circuit board may include a first substrate disposed on the housing 210 and a second substrate (or an extended substrate) extending from the first substrate. A connector may be disposed on the second substrate. In the second circuit board according to another embodiment, the terminal unit may be omitted, and the second controller may be electrically connected to or connected to the connector of the second circuit board. Alternatively, in another embodiment, the second controller may be omitted, and the coil 230 or the position sensor 240 may be electrically connected to or connected to the connector of the second circuit board. The connector of the second circuit board may be coupled to or connected to another external connector of the camera device 200 or connected to an external device. The connector of the second circuit board that connects to another external connector of the camera device may correspond to a fixed unit that does not move during OIS operation.
[0229] The fixing unit (e.g., housing 210) may include a receiving portion 49 in which at least a portion of the resilient member 30 is received or disposed. The receiving portion 49 may be recessed from the lower surface of the fixing unit (e.g., housing 210).
[0230] For example, at least a portion of the elastic member 30 may be connected to the receiving portion 49. The receiving portion 49 may be disposed on or formed in the lower surface 210A of the housing 210. The receiving portion 49 may be disposed on or formed in the lower portion 42 of the housing 210. The receiving portion 49 may be disposed on or formed in the lower surface 210A of the lower portion 42 of the housing 210. The receiving portion 49 may be disposed around the opening 18 in the housing 210. The receiving portion 49 may be formed in the region of the lower surface 210A of the lower portion 420 of the housing 210 adjacent to the opening 18 in the housing 210.
[0231] For example, the receiving portion 49 may be a recess that is recessed from the lower surface of the lower portion 42 of the housing 210. For example, the receiving portion 49 may include a bottom surface 49A that is stepped relative to the lower surface 210A of the housing 210 and a side surface (or sidewall) 49B disposed between the bottom surface 49A and the lower surface 210A of the housing 210.
[0232] The receiving portion 49 may correspond to, be opposite to, or overlap with the second connecting portion 32 of the elastic member 30. The second connecting portion 32 of the elastic member 30 may be disposed within the receiving portion 49. The second connecting portion 32 of the elastic member 30 may be connected to the receiving portion 49. The second connecting portion 32 may be connected to the receiving portion 49 via an adhesive. The second connecting portion 32 of the elastic member 30 may be connected to the bottom surface 49A of the receiving portion 49. A groove 79A may be formed in the bottom surface 49A to allow the adhesive to flow easily through it. Additionally, the groove 79A may inhibit the introduction of adhesive into the opening 60A in the housing 210.
[0233] At least one boss 4A configured to connect with the through hole 3A in the second connecting portion 32 of the elastic member 30 may be formed on the bottom surface 49A of the receiving portion 49.
[0234] The housing 210 may include a seating portion 69 in which at least a portion of the tilting guide unit 60 is disposed, or at least a portion of the tilting guide unit 60 is received in the seating portion 69. For example, the seating portion 69 may be a recess that is recessed from the bottom surface of the housing 210 or the upper surface of the lower portion 42.
[0235] For example, the seating portion 69 may have a shape corresponding to or consistent with the shape of the tilting guide unit 60. For example, the seating portion 69 may include a bottom surface 69A and a side surface 69B, the bottom surface 69A having a stepped portion formed along the optical axis from the upper surface of the lower portion 42 of the housing 210, and the side surface 69B connecting the bottom surface 69A to the upper surface of the lower portion 42. The side surface 69B may be referred to as a "partition wall" or "sidewall". For example, the bottom surface 69A of the seating portion 69 may be positioned lower than the upper surface of the lower portion 42 of the housing 210. In another embodiment, the seating portion 69 may be omitted.
[0236] Because the housing 210 has a seating portion 69 on its upper surface of the lower portion 42, in which at least a portion of the tilting guide unit 60 is inserted or disposed, the lower portion 42 of the housing 210 may include a partition wall 69B (or guide portion) surrounding the tilting guide unit 60. The tilting guide unit 60 may be spaced apart from the partition wall 69B of the housing 210, and the partition wall 69B may be configured to surround the tilting guide unit 60. The partition wall 69B of the housing 210 may prevent the tilting guide unit 60 from separating from or displacing from the housing 210. In another embodiment, at least a portion of the tilting guide unit 60 may contact the partition wall 69B of the housing 210.
[0237] For example, at least a portion of the first magnet unit 310A may correspond to, be opposite to, or overlap with the tilting guide unit 60 in a direction parallel to the first axis. Additionally, at least a portion of the second magnet unit 310B may correspond to, be opposite to, or overlap with the tilting guide unit 60 in a direction parallel to the second axis.
[0238] The housing 210 may include a recess 55 in which at least a portion of the boss 66 of the tilting guide unit 60 is disposed, or at least a portion of the boss 66 is received in the recess 55. The recess 55 in the housing 210 may be formed in the upper surface of the lower portion 42 of the housing 210. For example, the recess 55 may be recessed from the upper surface of the lower portion 42 of the housing 210. For example, the recess 55 may be formed in the bottom surface 69A of the sitting portion 69 of the housing 210. For example, the recess 55 may be recessed from the bottom surface 69A of the sitting portion 69 of the housing 210. The number of recesses 55 in the housing 210 may be equal to the number of bosses 66 of the tilting guide unit 60.
[0239] For example, recess 55 may include two recesses 55A and 55B spaced apart from each other. For example, the two recesses 55A and 55B may be spaced apart from each other in a second axial direction. For example, the direction in which recesses 55A and 55B in housing 210 are spaced apart from each other may intersect or be perpendicular to the direction in which two recesses 29A and 29B in sensor base 270 are spaced apart from each other. For example, receiving portion 49 may be disposed between the two recesses 55A and 55B in housing 210. Recess 55 in housing 210 may contact the boss 66 of tilting guide unit 60 at at least one point. For example, recess 55 may include a bottom surface and at least one side surface connected to the bottom surface. At least one side surface of recess 55 may be a tilted surface. For example, recess 55 may include a bottom surface and multiple tilted surfaces. The tilted surfaces of recess 55 may have the same shape. In another embodiment, at least one tilted surface of recess 55 may have a different shape than the other tilted surfaces.
[0240] The fixing unit (e.g., housing 210) may include an opening 18, in which at least a portion of the moving module (or tilting module) is disposed or extends through the opening 18. For example, housing 210 may include an opening 18, in which at least a portion of the sensor base 270 is disposed or extends through the opening 18.
[0241] The opening 18 exposes the extension 217 of the sensor base 270. The opening 18 exposes the first connecting portion 31 of the elastic member 30. In addition, the opening 18 exposes at least a portion of the connecting portion 33 of the elastic member 30.
[0242] For example, opening 18 may be provided in the seating portion 69. For example, opening 18 may be formed in the bottom surface 69A of the seating portion 69. Opening 18 may be formed through the bottom surface 69A of the seating portion 69. Opening 18 may be formed through the lower surface 210A of the lower portion 420. Opening 18 is necessary for the assembly of the elastic member 30 with the extension 217 of the sensor base 210. For example, opening 18 may be formed in the lower surface of the lower portion 42 of the housing 210. The shape of opening 18 in housing 210 may correspond to or be the same as the shape of the extension 217 of sensor base 270. Opening 18 in housing 210 may serve as an assembly passage for connecting the elastic member 30 to the extension 217 of sensor base 270. Therefore, the dimensions of opening 18, such as diameter, may be larger than the dimensions of the first connecting portion 31 of the elastic member 30. In this case, the size of the connecting member 31 can be the length of the connecting portion 31 in the direction perpendicular to the optical axis (the length in the transverse or longitudinal direction) or the diameter of the first connecting portion 31.
[0243] The moving module (or tilting module) may include at least a portion (or "extension") disposed in or extending through an opening 18 in the housing 210. At least a portion (or extension) of the moving module (or tilting module) may be connected to or coupled to the elastic member 30. For example, at least a portion (or extension) of the moving module (or tilting module) may be coupled to or connected to a first coupling portion 31 of the elastic member 30.
[0244] An extension 217 of the sensor base 270 may extend through an opening 60A in the tilting guide unit 60. The extension 217 of the sensor base 270 may be disposed within a fixing unit (e.g., housing 210). The extension 217 of the sensor base 270 may be connected to or coupled to an elastic member 30. For example, the extension 217 of the sensor base 270 may be connected to or coupled to a first coupling portion 31 of the elastic member 30. For example, the extension 217 of the sensor base 270 may include at least one boss 219 configured to couple to the elastic member 30 (e.g., the first coupling portion 31). The first coupling portion 31 of the elastic member 30 may include at least one through-hole 2A configured to couple to the boss 219 of the sensor base 270. In another embodiment, the first coupling portion 31 of the elastic member 30 may include a hole or recess instead of a through-hole 2A. In another embodiment, the extension 217 of the sensor base 270 may extend through an opening 18 in the housing 210.
[0245] While the sensor base 270 may include four bosses, in another embodiment, the number of bosses in the sensor base 270 may be one to three, or five or more. Additionally, the number of through holes 2A in the elastic member 30 may be equal to the number of bosses 219 in the sensor base 270. In another embodiment, the extension 217 of the sensor base 270 may include a recess or a hole, and the first connecting portion 31 of the elastic member 30 may include a boss.
[0246] Reference Figure 4a At least a portion of the extension 217 of the sensor base 270 may be disposed in the opening 18 in the housing 210. At least a portion of the extension 217 of the sensor base 270 may be exposed through the opening 18 in the housing 210.
[0247] The housing 210 may include a protrusion 215 projecting in a direction perpendicular to the optical axis. For example, the protrusion 215 may project from a side portion of the housing 210. For example, the protrusion 215 may project from the outer surface of the fourth side portion 71D of the housing 210. For example, the protrusion 215 may be formed by at least a portion of the fourth side portion 71D projecting in a direction parallel to a straight line extending through and perpendicular to the optical axis. For example, the protrusion 215 may include a recess 16A (or cavity) in which at least a portion of the fourth substrate 804 is disposed or received. For example, the recess 16A in the protrusion 215 may include an upwardly opening.
[0248] Reference Figure 10aThe recess 16A in the protrusion 215 may be provided with connecting recesses 215A and 215B for inserting, connecting, or fixing the motion-suppressing portion 80. For example, connecting recesses 215A and 215B may be formed in the inner surfaces of two facing faces of the recess 16A in the protrusion 215. For example, connecting recesses 215A and 215B may extend along the optical axis. For example, to facilitate insertion or connection of the motion-suppressing portion 80 from above, each of the connecting recesses 215A and 215B may include an opening leading to the upper surface of the protrusion 215.
[0249] The maximum length of the protrusion 215 in the optical axis direction can be less than the maximum length of the housing 210 in the optical axis direction. In this configuration, space for the outward extension of the circuit board 800 can be easily ensured, and a compact camera device can be achieved.
[0250] The camera device 200 may include a motion suppression portion 80 connected to at least a portion of the housing 210. The motion suppression portion 80 may suppress movement or displacement of at least a portion of the fourth substrate 804 to suppress deformation of the shape of at least a portion of the fourth substrate 804.
[0251] Reference Figure 7c , Figure 8 and Figure 11a The fourth substrate 804 of the circuit board 800 may include a first portion 804A (or "first region") connected to the first substrate 801, a second portion 804B connected to and bent from the first portion 804A, and a third portion 804C connected to and bent from the second portion 804B. In another embodiment, at least one of the first portion 804A or the second portion 804B may be omitted.
[0252] For example, the first portion 804B may extend in a direction parallel to the first substrate 801. For example, the second portion 804B may be bent from the first portion 804B and may extend from the first portion 804B in an upward direction. For example, the third portion 804C may extend from the second portion 804B in a direction opposite to that of the first portion 804A.
[0253] For example, the fourth substrate 804 may include a first bent portion 804D connecting the first portion 804A and the second portion 804B to each other. Additionally, the fourth substrate 804 may include a second bent portion 804E connecting the second portion 804B and the third portion 804C to each other. The first bent portion 804D and the second bent portion 804E may be at an angle, and for example, the first portion 804A and the second portion 804B may be perpendicular to each other. In another embodiment, the first bent portion 804D and the second bent portion 804E may be circular. In another embodiment, the interior angle between the first portion 804A and the second portion 804B may be an acute angle or an obtuse angle.
[0254] The first bending portion 804D and the second bending portion 804E can prevent the length of the camera device 200 from increasing in the direction perpendicular to the optical axis. Furthermore, since the first bending portion 804D and the second bending portion 804E are located between the upper surface of the camera device 200 (e.g., the upper surface of the cover member 300) and the lower surface of the camera device 200 (e.g., the lower surface of the housing 210), an increase in the length of the camera device 200 in the optical axis direction can be prevented, thereby enabling miniaturization of the camera device.
[0255] For example, the third portion 804C may take the form of a plate or plane perpendicular to the optical axis. For example, the third portion 804C may include a zigzag or meandering shape. For example, the third portion 804C may include at least one bent or curved region. For example, the bent or curved region of the third portion 804C may bend upwards in a second or third direction perpendicular to the optical axis. Alternatively, the bent or curved region of the third portion 804C may extend in a direction perpendicular to the optical axis. For example, when viewed from above, the third portion 804C may include regions having a U-shaped or V-shaped shape.
[0256] For example, the third portion 804C may be spaced apart from the housing 210. For example, the third portion 804C may be spaced apart from the protrusion 215 of the housing 210. In another embodiment, for example, at least a portion of the third portion 804C may contact the protrusion 215 of the housing 210.
[0257] At least a portion of the second portion 804B of the fourth substrate 804 may be disposed in the protrusion 215 of the housing 210. At least a portion of the second portion 804B of the fourth substrate 804 may be disposed in the recess 16A of the protrusion 215 of the housing 210. For example, at least a portion of the first portion 804A of the fourth substrate 804 may be disposed in the recess 16A of the protrusion 215 of the housing 210. The third portion 804C of the fourth substrate 804 may be located outside the protrusion 215 of the housing 210. For example, the third portion 804C of the fourth substrate 804 may be positioned higher than the protrusion 215 of the housing 210. The lower surface of the third portion 804C of the fourth substrate 804 may be positioned higher than the upper surface of the protrusion 215 of the housing 210.
[0258] Reference Figure 7a The sensor base 270 may include a recess 273, which is formed in the portion where the fourth substrate 804 and the first substrate 801 are connected or joined to each other, for example, at a position corresponding to the first portion 804A of the fourth substrate 804. The recess 273 may be configured to be adjacent to or abut against the outer surface of the fourth substrate 804 disposed thereon on the fourth side portion 51D of the sensor base 270. The recess 273 may be used to prevent the first portion 804A of the fourth substrate 804 from being damaged due to friction with the sensor base 270.
[0259] Connector 805 can be coupled or connected to another external connector of camera device 200 or to an external device. Connector 805 connected to another external connector can correspond to a fixed unit that does not move during OIS. Since the third portion 804C of the fourth substrate 804 includes at least one bent or flexed area, it can flexibly support camera device 200 or OIS moving unit and buffer external impacts. That is, the third portion 804C of the fourth substrate 804 can be used as a spring configured to buffer impacts. In addition, since the third portion 804C of the fourth substrate 804 can be used to flexibly support OIS moving unit 100, the driving force or driving power required to perform OIS can be reduced.
[0260] The camera device 200 may include a reinforcing member 70 disposed on at least a portion of the fourth substrate 804, connected to or attached to at least a portion of the fourth substrate 804. The reinforcing member 70 may be disposed on at least one of a first portion 804A or a second portion 804B of the fourth substrate 804, connected to or attached to at least one of the first portion 804A or the second portion 804B of the fourth substrate 804. For example, the reinforcing member 70 may be disposed on at least a portion of the first portion 804A and at least a portion of the second portion 804B of the fourth substrate 804, connected to or attached to at least a portion of the first portion 804A and at least a portion of the second portion 804B of the fourth substrate 804.
[0261] For example, the reinforcing member 70 may be disposed on the lower surface of the first portion 804A and the lower surface of the second portion 804B of the fourth substrate 804, and may be connected to or attached to the lower surfaces of the first portion 804A and the second portion 804B of the fourth substrate 804. For example, the reinforcing member 70 may include a first region 70A and a second region 70B, wherein the first region 70A is disposed on the first portion 804A and is connected to or attached to the first portion 804A, and the second region 70B is disposed on the second portion 804B and is connected to or attached to the second portion 804B. The second region 70B may be bent upward from the first region 70A. For example, a bent portion may be formed between the first region 70A and the second region 70B.
[0262] For example, the area of the second region 70B can be larger than the area of the first region 70A. In another embodiment, the two can be equal, or the area of the second region 70B can be smaller than the area of the first region 70A.
[0263] For example, the reinforcing member 70 may be spaced apart from the third portion 804C of the fourth substrate 804. For example, the second region 70B of the reinforcing member 70 may be spaced apart from the third portion 804C of the fourth substrate 804. In another embodiment, at least a portion of the second region 70B of the reinforcing member 70 may contact the third portion 804C of the fourth substrate 804.
[0264] In another embodiment, the reinforcing member 70 may be disposed on the upper surface of the first portion 804A and the upper surface of the second portion 804B of the fourth substrate 804, and may be coupled to or attached to the upper surface of the first portion 804A and the upper surface of the second portion 804B of the fourth substrate 804. For example, in another embodiment, the reinforcing member 70 may include a first region disposed on the upper surface of the first portion 804A of the fourth substrate 804 and a second region disposed on the upper surface of the second portion 804B of the fourth substrate.
[0265] In another embodiment, the reinforcing member 70 may be disposed on at least a portion of the second portion 804B and at least a portion of the third portion 804C of the fourth substrate 804, and connected to or attached to at least a portion of the second portion 804B and at least a portion of the third portion 804C of the fourth substrate 804. For example, in another embodiment, the reinforcing member 70 may be disposed on the second portion 804B and the third portion 804C of the fourth substrate 804, and connected to or attached to the second portion 804B and the third portion 804C of the fourth substrate 804. For example, the reinforcing member 70 may include a first region disposed on the second portion 804B of the fourth substrate 804, connected to or attached to the second portion 804B of the fourth substrate 804, and a second region disposed on the third portion 804C, connected to or attached to the third portion 804C, and a bent portion may be formed between the first region and the second region. The first region of the reinforcing member 70 may be disposed on the lower surface (or upper surface) of the second part 804B, and the second region of the reinforcing member 70 may be disposed on the lower surface (or upper surface) of the third part 804C.
[0266] The reinforcing member 70 can prevent the fourth substrate 804 from being damaged, deformed, or broken due to impact or external force. Additionally, the reinforcing member 70 can be used to suppress deformation and restore the shape of the fourth substrate 804 when it is subjected to force due to the tilt of the OIS moving unit 100. For example, the reinforcing member 70 may comprise at least one of a metallic material or an injection molding material.
[0267] For example, the reinforcing member 70 may be disposed in the recess 16A in the protrusion 215 of the housing 210. For example, at least a portion of the reinforcing member 70 may contact the recess 16A in the protrusion 215 of the housing 210. For example, the reinforcing member 70 may not be attached to the housing 210 (e.g., the protrusion 215). In another embodiment, for example, the reinforcing member 70 may be attached to the housing 210 (e.g., the protrusion 215) via an adhesive.
[0268] The reinforcing member 70 may include an opening 73. The opening 73 in the reinforcing member 70 may open or expose at least a portion of the fourth substrate 804 of the circuit board 800. For example, the opening 73 may open or expose at least a portion of each of the first portion 804A (or “first region”) and the second portion 804B (or “second region”) of the fourth substrate 804. The opening 73 in the reinforcing member 70 may be a hole, a through-hole, or a hollow portion.
[0269] An opening 73 may be formed in at least one of the first region 70A or the second region 70B of the reinforcing member 70. For example, an opening 73 may be formed in each of the first region 70A and the second region 70B of the reinforcing member 70. Additionally, an opening 73 may open or expose at least a portion of the first bent portion 804D. In another embodiment, an opening 73 may be formed only in one of the first region 70A and the second region 70B of the reinforcing member 70. In another embodiment, an opening 73 may not expose the first bent portion 804D. An opening 73 may reduce the elastic modulus of the second substrate 802 of the circuit board 800 connected to the reinforcing member 70, thereby facilitating the movement of the OIS moving unit during OIS operation. That is, an opening 73 may reduce the elasticity of the circuit board 800 supporting the OIS moving unit, such as the second substrate 802, thereby facilitating OIS operation with less driving force and reducing power consumption. Here, the driving force may be the force generated by the interaction between the coil 230 and the magnet 310. In another embodiment, the reinforcing member 70 may not have an opening 73.
[0270] The motion suppression portion 80 can be connected to the protrusion 215 of the housing 210. For example, the motion suppression portion 80 can be connected to the connecting recesses 215A and 215B in the protrusion 215 of the housing 210. At least a portion of the second portion 804B of the fourth substrate 804 can be disposed between the motion suppression portion 80 and the inner surface of the protrusion 215 of the housing 210. For example, at least a portion of the reinforcing member 70 can be disposed between the motion suppression portion 80 and the inner surface of the protrusion 215 of the housing 210. The motion suppression portion 80 can be spaced apart from the circuit board 800 in a second direction (X-axis direction) or a third direction (Y-axis direction). For example, the motion suppression portion 80 can be spaced apart from the circuit board 800 in the optical axis direction or in a direction perpendicular to the optical axis direction. That is, the motion suppression portion 80 can be used to maintain the shape of the bent portions 804D and 804E of the fourth substrate 804, which is a flexible substrate. For example, the motion suppression portion 80 can be formed by injection molding a non-magnetic material or resin. In another embodiment, the motion suppression portion 80 may contact at least a portion of the fourth substrate 804 of the circuit board 800.
[0271] The movement or movement of at least a portion of the second portion 804B of the fourth substrate 804 disposed in the recess 16A in the protrusion 215 can be restricted by the motion suppression portion 80, and the second portion 804B can be suppressed or prevented from moving out of the recess 16A in the protrusion 215. This can suppress or prevent the OIS moving unit from being affected by the restoring force of the fourth substrate 804 when performing OIS, thereby enabling accurate OIS performance and improving the reliability of OIS operation. The motion suppression portion 80 can be alternatively referred to as a "clamping member".
[0272] The cover member 300 can form a receiving space with the housing 210, and the OIS moving unit can be disposed in the receiving space. For example, the cover member 300 can take the form of a box-shaped piece with an open lower portion. For example, the cover member 300 can include an upper plate 301 and a side plate 302 connected to the upper plate 301.
[0273] The lower end of the side plate 302 of the cover member 300 can be connected to the housing 210. The upper plate 301 of the cover member 300 can be polygonal (e.g., quadrilateral or octagonal) or circular. The upper plate 301 of the cover member 300 may include an opening 303 configured to expose a lens (not shown) to external light. The opening 303 may be a through-hole formed along the optical axis through the upper plate 301 of the cover member 300. For example, the cover member 300 may include multiple side plates. The material of the cover member 300 can be a non-magnetic material. In another embodiment, the cover member 300 may be made of a magnetic material. For example, the material of the cover member 300 may be an injection-molded material, such as resin or metal.
[0274] The cover member 300 may include an opening 304 disposed or formed in the side plate 302 to avoid spatial interference with the protrusion 215 of the housing 210. For example, the protrusion 215 of the housing 210 may extend through the opening 304 of the cover member 300 and may protrude from the side plate 302 of the cover member 300.
[0275] The cover member 300 may include a protrusion 305 disposed above the opening 304 and protruding from the side plate 302. For example, the protrusion 305 may be plate-shaped. For example, the protrusion 305 of the cover member 300 may be disposed on the protrusion 215 of the housing 210. For example, the protrusion 305 may be disposed above the recess 16A in the protrusion 215 of the housing 210. For example, the protrusion 305 may be disposed above the motion suppression portion 80. For example, the protrusion 305 may overlap with the motion suppression portion 80 in the optical axis direction. In addition, for example, the protrusion 305 may overlap with the first portion 804A of the fourth substrate 804 in the optical axis direction. The protrusion 305 may suppress or prevent separation of the motion suppression portion 80 and may protect the motion suppression portion 80 and the fourth substrate 804 from impact.
[0276] Reference Figure 4g The cover member 300 may include a boss 311 protruding from the upper plate 301. In this case, the boss 311 of the cover member 300 may protrude from the inner surface of the upper plate 301 toward the spool 110 or the rolling member 21. For example, the boss 311 of the cover member 300 may be opposite to or overlap with the receiving portion 116 of the spool 110 in the optical axis direction. At least a portion of the boss 311 of the cover member 300 may be inserted into or disposed in the receiving portion 116 of the spool 110. The boss 311 of the cover member 300 may be disposed on the rolling member 21.
[0277] For example, the cover member 300 may include a first boss 311A that corresponds to, is opposite to, or overlaps with the first receiving portion 116A of the first rolling member 21A or the spool 110. For example, the cover member 300 may include a second boss 311B that corresponds to, is opposite to, or overlaps with the second receiving portion 116B of the second rolling member 21B or the spool 110. For example, the boss 311 of the cover member 300 may include a recess recessed from the upper surface of the upper plate 301 of the cover member 330. In another embodiment, the boss of the cover member 300 may not include a recess. Because the cover member 300 is provided with a boss 311, this embodiment can prevent the rolling member 21 from separating from the receiving portion 116 of the spool 110. Additionally, the boss 311 of the cover member 300 can serve as a stop configured to prevent the spool 110 from moving further upward within a limited range. In another embodiment, the boss 311 may not be formed on the cover member 300.
[0278] Next, the support unit will be described.
[0279] The support unit can be disposed between the fixed unit and the OIS moving unit 100. The support unit can be disposed between the sensor base 270 and the housing 210, and can support the sensor base 270 relative to the housing 210.
[0280] The support unit may include a tilt guide unit 60 disposed between the OIS moving unit (e.g., sensor base 270) and the fixed unit (e.g., housing 210). The tilt guide unit 60 can guide the tilt of the OIS moving unit 100.
[0281] The tilting guide unit 60 may alternatively be referred to as a drive plate, "mover", "mover plate", "drive plate", "plate", "rotating plate", "tilting plate", "moving plate" or "support plate".
[0282] The tilt guide unit 60 is capable of tilting or rotating about a first axis or a second axis by a predetermined angle. For example, the tilt guide unit 60 may be disposed between the lower portion (or lower surface) of the sensor base 270 and the lower portion 42 of the housing 210. For example, at least a portion of the tilt guide unit 60 may be disposed in the mounting portion 69 of the housing 210. Since the tilt guide unit 60 is disposed in the mounting portion 69 of the housing 210, the length or height of the camera device 200 in the optical axis direction can be reduced.
[0283] The tilting guide unit 60 may be plate-shaped. The tilting guide unit 60 may include a body. The body of the tilting guide unit 60 may alternatively be referred to as a main body or "plate portion". When viewed from above, the shape of the body of the tilting guide unit 60 may be polygonal (e.g., quadrilateral), circular, or elliptical. When viewed from above, the shape of the body of the tilting guide unit 60 may be quadrilateral, and the corner (or edge) portions of the body may be rounded.
[0284] For example, the length of the tilting guide unit 60 in the horizontal direction perpendicular to the optical axis (e.g., in the lateral or longitudinal direction) can be greater than the length of the tilting guide unit 60 in the optical axis direction.
[0285] The tilting guide unit 60 may include a first guide member disposed on a first surface (or upper surface) 6A opposite to the OIS moving unit (e.g., sensor base 270) and a second guide member disposed on a second surface (or lower surface) 6B opposite to the fixed unit (e.g., housing 210). One or more first guide members may be provided, and one or more second guide members may be provided. For example, a first axis may be formed by the first guide member, and a second axis may be formed by the second guide member. For example, the first guide member may include a plurality of first guide members spaced apart from each other in a direction parallel to the first axis. The second guide member may include a plurality of second guide members spaced apart from each other in a direction parallel to the second axis. For example, the first axis may be formed by a plurality of first guide members, and the second axis may be formed by a plurality of second guide members.
[0286] The first guide member can be a "boss", "protrusion", "spherical member" or "ball", and the second guide member can be a "boss", "protrusion", "spherical member" or "ball".
[0287] Reference Figure 9a and Figure 9b The tilting guide unit 60 may include a first boss 65 connected to or in contact with the sensor base 270 and a second boss 66 connected to or in contact with the housing 210. The first boss 65 may be disposed on a first surface 6A (e.g., the upper surface) of the tilting guide unit 60, and the second boss 66 may be disposed on a second surface 6B (or lower surface) of the tilting guide unit 60 opposite to the first side 6A. For example, the first boss 65 may protrude from the first surface 6A (e.g., the upper surface) of the tilting guide unit 60, and the second boss 66 may protrude from the second surface 6B (e.g., the lower surface) of the tilting guide unit 60.
[0288] The first boss 65 may alternatively be referred to as an "upper boss (or front boss)" or "first protrusion," and the second boss 66 may alternatively be referred to as a "lower boss (or rear boss)" or "second protrusion." The number of each of the first boss 65 and the second boss 66 may be one, two, three, or more. At least a portion of the first boss 65 may be disposed in a recess 29 in the sensor base 270. The first boss 65 may include at least two bosses 65A and 65B. For example, 1-1 boss 65A and 1-2 boss 65B may be spaced apart from each other in a first axial direction. Each of the two bosses 65A and 65B may be inserted into and disposed in a corresponding one of the first recess 29A and the second recess 29B in the sensor base 270. In another embodiment, the two bosses 65A and 65B may be spaced apart from each other in a first horizontal direction or an X-axis direction.
[0289] At least a portion of the second boss 66 may be disposed in the recess 55 in the housing 210. The second boss 66 may include at least two bosses 66A and 66B. For example, 2-1 bosses 66A and 2-2 bosses 66B may be spaced apart from each other in the second axial direction. Each of the two bosses 66A and 66B may be inserted into and disposed in a corresponding one of the first recess 55A and the second recess 55B in the housing 210. In another embodiment, the two bosses 66A and 66B may be spaced apart from each other in the second horizontal direction or the Y-axis direction.
[0290] In another embodiment, the two protrusions 65A and 65B of the tilting guide unit 60 can be spaced apart from each other in the second axial direction, the first recess 29A and the second recess 29B in the sensor base 270 can be spaced apart from each other in the second axial direction, the two protrusions 66A and 66B of the tilting guide unit 60 can be spaced apart from each other in the first axial direction, and the first recess 55A and the second recess 55B in the housing 210 can be spaced apart from each other in the first axial direction.
[0291] For example, each of the first boss 65 and the second boss 66 may have a curved shape, a hemispherical shape, a dome shape, or a polyhedral shape, but this disclosure is not limited thereto. For example, the shape of the first boss 65 when viewed from the front or above and the shape of the second boss 66 when viewed from the rear or below may be circular, elliptical, or polygonal.
[0292] The tilt guide unit 60 may include an opening 60A that corresponds to, is opposite to, or overlaps with the extension 217 of the sensor base 270 or the elastic member 30. For example, the opening 60A in the tilt guide unit 60 may correspond to, be opposite to, or overlap with the extension 217 of the sensor base 270 in the optical axis direction. The weight of the tilt guide unit 60 can be reduced by the opening 60A, which can result in a lighter camera device 200.
[0293] For example, the opening 60A in the tilt guide unit 60 can be provided at a position corresponding to the extension 217 to avoid spatial interference with the extension 217 of the sensor base 2170. Alternatively, the opening 60A in the tilt guide unit 60 can be configured to avoid spatial interference with the extension 217 of the elastic member 30.
[0294] For example, the opening 60A in the tilting guide unit 60 can be a through hole or a hollow portion. For example, the opening 60A can be formed through the tilting guide unit 60 in the first direction (Z-axis direction) or the optical axis direction. For example, at least a portion of the opening 60A in the tilting guide unit 60 can have a shape corresponding to the extension 217 of the sensor base 270. For example, the opening 60A can have a circular shape, an elliptical shape, and a polygonal shape, such as a quadrilateral shape.
[0295] When viewed from above, the opening 60A in the tilt guide unit 60 can be located between the bosses 65A and 65B of the tilt guide unit 60. When viewed from below, the opening 60A in the tilt guide unit 60 can be located between the bosses 66A and 66B of the tilt guide unit 60.
[0296] For example, the length of the opening 60A in the tilting guide unit 60 in the lateral (or longitudinal) direction may be longer than the length or diameter of the extension 217 of the sensor base 270 in the lateral (or longitudinal) direction. In another embodiment, the length of the opening 60A in the lateral (or longitudinal) direction may be equal to the length or diameter of the extension 217 of the sensor base 270 in the lateral (or longitudinal) direction.
[0297] At least a portion of the extension 217 of the sensor base 270 may be disposed in the opening 60A in the tilt guide unit 60. For example, the extension 217 of the sensor base 270 may overlap with the opening 60A in the tilt guide unit 60 in the optical axis direction. Alternatively, for example, at least a portion of the extension 217 of the sensor base 270 may overlap with the tilt guide unit 60 in a direction perpendicular to the optical axis direction. This can reduce the length or height of the camera device 200 in the optical axis direction. For example, at least a portion of the opening 60A may be disposed between the two bosses 65A and 65B of the first boss 65 of the tilt guide unit 60. Additionally, at least a portion of the opening 60A may be disposed between the bosses 66A and 66B of the second boss 66 of the tilt guide unit 60.
[0298] For example, the tilt guide unit 60 can be made of injection-molded material. For example, the tilt guide unit 60 can be made of plastic, resin, or ceramic material. In another embodiment, the tilt guide unit 60 can include a metallic material, such as SUS. Additionally, the tilt guide unit 60 can be made of a non-magnetic material. In another embodiment, the tilt guide unit 60 can be made of a magnetic material.
[0299] The bosses 65A and 65B of the first boss 65 and the bosses 66A and 66B of the second boss 66 can be arranged side by side in directions that intersect or are perpendicular to each other. The first boss 65 of the tilting guide unit 60 can cause the OIS moving unit to rotate, pivot, or tilt by a predetermined angle about a first axis. The second boss 66 of the tilting guide unit 60 can cause the OIS moving unit to rotate, pivot, or tilt about a second axis.
[0300] In another embodiment, at least one of the first boss 65 or the second boss 66 of the tilting guide unit 60 may be omitted, and a rolling member or a ball member may be provided in place of the omitted boss.
[0301] Reference Figure 9c and Figure 9d According to another embodiment, the tilting guide unit 60-1 may include a first recess 75 and omit the first boss 65, and may include a second recess 76 and omit the second boss 66. Additionally, the support unit may include a first ball member in place of the first boss 65, and may include a second ball member in place of the second boss 66. For example, the first ball member may include two or more first ball members 65A1 and 65B1, and the second ball member may include two or more ball members 66A1 and 66B1.
[0302] The first recess 75 may be disposed or formed in the first surface 6A of the tilting guide unit 60-1. The first surface 6A may be a surface opposite to or facing the sensor base 270. The recess 75 may be recessed from the first surface 6A of the tilting guide unit 60-1. For example, the tilting guide unit 60-1 may include first recesses 75A and 75B, with at least a portion of the first ball member 65A1 and at least a portion of the first ball member 65B1 respectively disposed in the first recesses 75A and 75B. For example, the first recesses 75A and 75B may be spaced apart from each other in the first axial direction. For example, the first ball members 65A1 and 65B1 may be spaced apart from each other in the first axial direction.
[0303] In another embodiment, the first ball members 65A1 and 65B1 may be arranged to be spaced apart from each other in the second axial direction, and the first recesses 75A and 75B may be arranged to be spaced apart from each other in the second axial direction.
[0304] In another embodiment, the first ball members 65A1 and 65B1 and the first recesses 75A and 75B may be arranged to be spaced apart from each other in a first horizontal direction (or a second horizontal direction).
[0305] Furthermore, the second recess 76 in the tilting guide unit 60-1 can be provided or formed in the second surface 6B of the tilting guide unit 60-1. The second surface 6B can be a surface opposite to or facing the housing 210. Alternatively, the second surface 6B can be a surface opposite to the first surface 6A of the tilting guide unit 60-1. The second recess 76 can be recessed from the second surface 6B of the tilting guide unit 60.
[0306] For example, the tilting guide unit 60-1 may include second recesses 76A and 76B, with at least a portion of the second ball member 66A1 and at least a portion of the second ball member 66B1 respectively disposed in the second recesses 76A and 76B. For example, the second recesses 76A and 76B may be spaced apart from each other in a second axial direction. For example, the second ball members 66A1 and 66B1 may be spaced apart from each other in a second axial direction. In another embodiment, the second ball members 66A1 and 66B1 may be spaced apart from each other in a first axial direction, and the second recesses 76A and 76B may be spaced apart from each other in a first axial direction. In another embodiment, the second ball members 66A1 and 66B1 and the second recesses 76A and 76B may be spaced apart from each other in a second horizontal direction (or a first horizontal direction).
[0307] The description of the shape of the recess 29 in the sensor base 270 or the recess 55 in the housing 210 can be applied, or similarly applied, to the shape of the first recess 75 and the second recess 76 in the tilting guide unit 60-1.
[0308] Lubricant can be provided on the first boss 66 of the tilt guide unit 60 and in the recess 29 of the sensor base 270, or in the second boss 66 of the tilt guide unit 60 and in the recess 55 of the housing 210, in order to reduce friction and protect the tilt guide unit 60.
[0309] The first boss 65 of the tilt guide unit 60 can slide in the recess 29 in the sensor base 270, and the second boss 66 can slide in the recess 55 in the housing 210. This reduces the friction between the tilt guide unit 60 and the sensor base 270, and / or the friction between the tilt guide unit 60 and the housing 210, and also reduces the current or power consumption required for OIS operation.
[0310] The rolling member 21 may not overlap with the tilting guide unit 60 in the optical axis direction. For example, as Figure 4c As shown, the rolling member 21 may not overlap with the tilting guide unit 60 in a direction perpendicular to the optical axis.
[0311] For example, the direction in which the first rolling member 21A and the second rolling member 21B are spaced apart from each other may intersect with the direction in which the bosses 65A and 65B of the tilting guide unit 60 are spaced apart from each other. For example, the direction in which the first rolling member 21A and the second rolling member 21B are spaced apart from each other may not be parallel or perpendicular to the direction in which the bosses 65A and 65B of the tilting guide unit 60 are spaced apart from each other.
[0312] For example, the direction in which the first rolling member 21A and the second rolling member 21B are spaced apart from each other may intersect with the direction in which the bosses 66A and 66B of the tilting guide unit 60 are spaced apart from each other. For example, the direction in which the first rolling member 21A and the second rolling member 21B are spaced apart from each other may not be parallel or perpendicular to the direction in which the bosses 66A and 66B of the tilting guide unit 60 are spaced apart from each other.
[0313] For example, when viewed from above, the distance between the bosses 65A and 65B of the tilting guide unit 60 can be less than the distance between the first rolling member 21A and the second rolling member 21B. In another embodiment, the distance between the bosses 65A and 65B of the tilting guide unit 60 can be equal to or greater than the distance between the first rolling member 21A and the second rolling member 21B.
[0314] For example, when viewed from above, the distance between bosses 66A and 66B of the tilting guide unit 60 can be less than the distance between the first rolling member 21A and the second rolling member 21B. In another embodiment, the distance between bosses 66A and 66B of the tilting guide unit 60 can be equal to or greater than the distance between the first rolling member 21A and the second rolling member 21B.
[0315] The support unit may include an elastic member 30 configured to connect the OIS moving unit (e.g., sensor base 270) to a fixed unit (e.g., housing 210). The elastic member 30 may be an elastic element, a spring, a coil spring, a suspension wire, or a leaf spring. For example, the elastic member 30 may be made of an elastic material. For example, the elastic member 30 may be made of metal. For example, the elastic member 30 may be subjected to a restoring force such as tension (or contraction).
[0316] For example, at least another portion of the elastic member 30 may be coupled to or connected to the housing 210. For example, at least another portion of the elastic member 30 may be coupled to or connected to the lower portion 42 of the housing 210. For example, at least another portion of the elastic member 30 may be coupled to or connected to the receiving portion 49 of the housing 210.
[0317] Figure 12a This is a cross-sectional perspective view of the camera assembly. Figure 12b yes Figure 12a Enlarged view of the area indicated by the dashed line. Figure 12c yes Figure 4a A magnified view of a section of the cross-section, and Figure 12d yes Figure 4f A magnified view of a portion of the cross-sectional view.
[0318] Reference Figures 11a to 12d The elastic member 30 may include a first connecting portion 31 connected to or coupled to the movable unit 100, a second connecting portion 32 connected to or coupled to the fixed unit, and a connecting portion 33 connecting the first connecting portion 31 to the second connecting portion 32. For example, the first connecting portion 31 may be connected to or coupled to an extension 217 of the sensor base 270. For example, the second connecting portion 32 may be connected to or coupled to a receiving portion 49 of the housing 210. The first connecting portion 31 may be alternatively referred to as the "first portion" or "first region," the second connecting portion 32 may be alternatively referred to as the "second portion" or "second region," and the connecting portion 33 may be alternatively referred to as the "third portion" or "third region."
[0319] The elastic member 30 may alternatively be referred to as a "buffer," "elastic part," "connecting elastic part," "elastic unit," "connecting elastic unit," or "spring part." The elastic member 30 may be an elastic body. For example, the elastic member 30 may be a spring, a leaf spring, or a suspension spring.
[0320] The first connecting portion 31 may include a connecting area or a body. In another embodiment, the first connecting portion 31 may include a plurality of connecting areas or connecting portions spaced apart from each other.
[0321] The second connecting portion 32 may include multiple connecting regions or connecting portions 32A and 32B. In another embodiment, the number of connecting regions of the second connecting portion 32 may be three or more. In another embodiment, the connecting regions of the second connecting portion 32 may be connected to each other. For example, the second connecting portion 32 may include a connecting region or body surrounding the opening 18 in the housing 210. To balance the restoring force of the elastic member 30, the connecting regions 32A and 32B may have symmetrical shapes. To balance the restoring force, the connecting regions 32A and 32B may be arranged symmetrically to each other.
[0322] The connecting portion 33 may have at least one bend or be at an angle. The connecting portion 63 may include at least one bend. For example, the connecting portion 63 may have a zigzag shape, with at least one bending area or at least one bend area.
[0323] The connecting portion 33 may include multiple connecting portions. Although in Figure 11bThe figure shows four connecting portions, but the number of connecting portions 33 is not limited to this. In another embodiment, the number of connecting portions 33 can be one, two, or more. Multiple connecting portions can have a shape symmetrical about the first connecting portion 31. Furthermore, multiple connecting portions can be arranged symmetrically about the first connecting portion 31. Therefore, the restoring force of the elastic member 30 can act symmetrically on the OIS moving unit, thereby preventing the OIS moving unit from accidentally tilting due to the elastic member 30.
[0324] The width K1 of the connecting portion 33 can be smaller than the width K2 of the second connecting portion 32. The width K1 of the connecting portion 33 can be its width in a direction perpendicular to the longitudinal direction of the connecting portion 33. The longitudinal direction of the connecting portion 33 can be the direction in which the connecting portion 33 extends to connect the first connecting portion 31 to the second connecting portion 32. The width K2 of the second connecting portion 31 can be its length in a direction perpendicular to the optical axis. The width K1 of the connecting portion 33 can be smaller than the width or diameter of the first connecting portion 310.
[0325] Despite Figures 11a to 12b The figure shows a single elastic member 30, but in another embodiment, the camera device 200 may include two or more elastic members spaced apart from each other. Each elastic member may include a first connecting portion 31, a second connecting portion 32, and a connecting portion 33.
[0326] The elastic member 30 may be disposed below the tilting guide unit 60. At least a portion of the elastic member 30, such as the connecting portion 33, may be disposed below the opening 60A in the tilting guide portion 60. The elastic member 30 may be opposite to or overlap with the opening 60A in the tilting guide unit 60 in the optical axis direction. For example, the elastic member 30 may not overlap with the tilting guide unit 60 in the optical axis direction. Alternatively, for example, at least a portion of the elastic member 30 may overlap with the tilting guide unit 60 in a direction perpendicular to the optical axis.
[0327] The moving module may include a portion (or "first portion") extending through or disposed within the opening 60A in the tilt guide unit 60. An elastic member 30 may be coupled to the first portion of the moving module. The fixing unit may include an opening 18 in which the first portion of the moving module is disposed. At least a portion of the extension 217 of the sensor base 270 may correspond to, be opposite to, or overlap with the opening 60A in the tilt guide unit 60 in the optical axis direction. For example, the extension 217 may not overlap with the tilt guide unit 60 in the optical axis direction. In another embodiment, a portion of the extension 217 may overlap with the tilt guide unit 60 in the optical axis direction. At least a portion of the extension 217 may be disposed within the opening 60A in the tilt guide unit 60. For example, at least a portion of the extension 217 may extend through the opening 60A in the tilt guide unit 60. For example, at least a portion of the extension 217 may extend through or penetrate the opening 60A in the tilting guide unit 60 and may be connected to the first connection portion 31 of the elastic member 30.
[0328] The end (or lower surface) of the extension 217 of the sensor base 270 may be positioned lower than the lower surface of the tilt guide unit 60. In another embodiment, the end of the extension 217 may be located in the opening 60A in the tilt guide unit 60. In another embodiment, the end (or lower surface) of the extension 217 may be disposed between the upper and lower surfaces of the tilt guide unit 60.
[0329] In one embodiment, the extension 217 may correspond to a portion of the sensor base 270 and may be integrally formed with the sensor base 270. A camera device according to another embodiment may include a connecting member separate from the sensor base 270, instead of the extension 217. In this case, the separate connecting member may be connected to the sensor base 270. For example, the connecting member may be connected to the sensor base 270 by an adhesive. For example, the connecting member may include a first connecting structure (e.g., a boss or recess), and the sensor base 270 may include a second connecting structure (e.g., a recess or boss) for connection to the first connecting structure. For example, one end of the connecting member may be connected to a lower portion (or lower surface) of the sensor base 270, and the other end of the connecting member may be connected to a first connecting portion 31 of the elastic member 30. At least a portion of the connecting member may be disposed in an opening 60A in the tilt guide unit 60. The connecting member may extend through the opening 60A in the tilt guide unit 60 and may be connected to the first connecting portion 31 of the elastic member 30. In this case, the sensor base 270 may not include the portion located in the opening 60A in the tilt guide unit 60.
[0330] In one embodiment, the elastic member 30 can be connected to an extension 217 of the sensor base 270, which extends through an opening 60A in the tilting guide unit 60, and the first connecting portion 31 of the elastic member 30 can not overlap with the tilting guide unit 60 in the optical axis direction. The first connecting portion 31 of the elastic member 30 can overlap with the opening 60A in the tilting guide unit 60 in the optical axis direction. The first connecting portion 31 of the elastic member 30 can overlap with the opening 18 in the housing 210 in the optical axis direction. The second connecting portion 32 of the elastic member 30 can overlap with the tilting guide unit 60 in the optical axis direction.
[0331] The elastic member 30 may not overlap with the tilting guide portion 60 in a direction perpendicular to the optical axis. In another embodiment, the elastic member 30 may overlap with the tilting guide unit 60 in a direction perpendicular to the optical axis. The elastic member 30 may overlap with the housing 210 in a direction perpendicular to the optical axis.
[0332] When viewed from above, the size (e.g., diameter) of the opening 60A in the tilting guide unit 60 can be larger than the size (e.g., diameter or length in the direction perpendicular to the optical axis) of the first connecting portion 31.
[0333] The elastic member 30 connecting the OIS moving unit and the fixed unit can apply a restoring force FR (see...). Figure 12cFor example, a contractile force or a force that pulls the OIS moving unit. The tilting guide unit 60 can be pushed relative to the OIS moving unit 100 by means of the elastic member 30. The tilting guide unit 60 can be in contact or in close contact with the OIS moving unit 100 by means of the elastic member 30. The tilting guide unit 60 can be held in contact with the OIS moving unit 100 by means of the elastic member 30.
[0334] Specifically, the tilting guide unit 60 can be pushed by the OIS moving unit and the fixed unit by means of the elastic member 30. In other words, the tilting guide unit 60 can be pushed to the moving unit by means of the restoring force FR of the elastic member 30.
[0335] In the case where the elastic member 30 is, for example, a leaf spring, the first connecting portion 31 and the second connecting portion 32 can be located at the same height in their normal state before assembly. When the first connecting portion 31 is assembled with the extension portion 217, the first connecting portion 31 can be positioned higher than the second connecting portion 32, thereby generating a restoring force FR to return the first connecting portion 31 to its normal position.
[0336] In other words, a predetermined height difference DP in the optical axis direction can exist between the first connecting portion 31 and the second connecting portion 32 (refer to...). Figure 12c For example, the first connecting portion 31 may be positioned higher than the second connecting portion 32 in the optical axis direction. For example, the first connecting portion 31 may be configured to be lower than the lower surface of the tilting guide unit 60.
[0337] Image sensor 810 can be positioned closer to first connection portion 31 than to second connection portion 32. The optical axis distance between image sensor 810 and first connection portion 31 can be smaller than the optical axis distance between image sensor 810 and second connection portion 31. Filter 610 can be positioned closer to first connection portion 31 than to second connection portion 32. The optical axis distance between filter 610 and first connection portion 31 can be smaller than the optical axis distance between filter 610 and second connection portion 31.
[0338] The first connecting portion 31 may be positioned higher than the lowest end (or lowest point) of the boss 66 of the tilt guide unit 60. In another embodiment, the first connecting portion 31 may be located at a level equal to or lower than the lowest end (or lowest point) of the boss 66 of the tilt guide unit 60.
[0339] The second connecting portion 32 may be positioned lower than the lowest end (or lowest point) of the boss 66 of the tilt guide unit 60. In another embodiment, the second connecting portion 32 may be located at a level equal to or lower than the lowest end (or lowest point) of the boss 66 of the tilt guide unit 60.
[0340] For example, the predetermined height difference DP can be less than the length of the extension 217 in the optical axis direction. For example, the predetermined height difference DP can be less than the length H1 of the tilting guide unit 60 in the optical axis direction. In another embodiment, the height difference DP can be equal to or greater than the length H1 of the tilting guide unit 60 in the optical axis direction. The length H1 can be the distance between the upper and lower surfaces of the body of the tilting guide unit 60.
[0341] The predetermined height difference DP can be used to assist in the preloading of the elastic member 30. The elastic member 30 can generate an elastic restoring force capable of returning the elastic member 30 to its normal position. The restoring force FR can be a force that pulls the OIS moving unit toward the fixed unit. The restoring force FR can also be a force that pulls the first connecting portion 31 toward the second connecting portion 32.
[0342] The predetermined height difference DP can be less than the distance DK between the first connecting portion 31 and the lower surface of the housing 210. In another embodiment, the distance DK can be the distance between the lower surface of the extension portion 217 and the lower surface of the housing 210. The distance DK can be less than the length of the extension portion 217 in the optical axis direction. The distance DK can be equal to or less than the length H1 of the tilting guide unit 60 in the optical axis direction. In another embodiment, the distance DK can be greater than the length H1.
[0343] With the help of the restoring force FR, the tilt guide unit 60 can be made to make close contact with the OIS moving unit and the fixed unit, and stably support the OIS moving unit.
[0344] In addition, since the first connecting portion 310 of the elastic member 30 is connected to the extension portion 217 corresponding to or opposite to the central region of the lower surface of the sensor base 270, the restoring force of the elastic member 30 can be concentrated in the central region of the sensor base 270, thereby efficiently and stably supporting the OIS moving unit.
[0345] With the aid of the restoring force FR of the elastic member 30, the lower surface of the sensor base 270 can push the tilt guide unit 60. The lower portion 42 of the housing 210 can press the tilt guide unit 60 due to the restoring force of the elastic member 30. Therefore, the first boss 65 and the second boss 66 of the tilt guide unit 60 can be in close contact with the sensor base 270 and / or the housing 210. The tilt guide unit 60 can stably support the OIS moving unit 100 relative to the fixed unit due to the restoring force of the elastic member 30, thereby enabling stable OIS operation.
[0346] If the restoring force FR is too low, the tilt guide unit 60 cannot stably support the OIS moving unit 100 relative to the fixed unit. At the same time, if the restoring force FR is too high, the electromagnetic force required for shaky hand compensation between the coil 230 and the magnet 130 may increase significantly, and power consumption may increase.
[0347] The magnitude of the restoring force FR can be controlled based on the distance between the first connecting portion 31 and the second connecting portion 32 in the optical axis direction and / or the width K1 of the connecting portion 33. In order to stably support the OIS moving unit 100 and prevent excessive increase in electromagnetic force and power consumption for hand tremor compensation, the width K1 of the connecting portion 33 can be smaller than the width K2 of the second connecting portion 32.
[0348] Additionally, to stably support the OIS moving unit 100 and prevent excessive increase in electromagnetic force and power consumption for shaky compensation, the first connecting portion 31 can be positioned lower than the lower surface of the tilting guide unit 60. Alternatively, the first connecting portion 31 can be positioned higher than the bottom surface 49A of the receiving portion 49 of the housing 210. The first connecting portion 31 can be positioned lower than the bottom surface 69A of the sitting portion 69 of the housing 210.
[0349] In another embodiment, the first connecting portion 31 may be disposed in the opening 60A in the tilting guide unit 60. In another embodiment, for example, the first connecting portion 31 may overlap with the tilting guide unit 60 in a direction perpendicular to the optical axis.
[0350] In another embodiment, the mounting portion 69 of the housing 210 can be omitted, and a mounting portion corresponding to or the same as the mounting portion 69 of the housing 210 can be formed on the lower surface of the sensor base 270, and the tilting guide unit 60 can be provided in the mounting portion of the sensor base 270.
[0351] In another embodiment, the tilt guide unit 60 can be omitted, and the support unit can include a rolling member, such as a ball member, disposed between the sensor base 270 and the housing 210. In this case, the rolling member can include two first ball members disposed in a direction parallel to the first axis and two second ball members disposed in a direction parallel to the second axis, and the OIS moving unit can tilt or rotate a predetermined angle about the first ball members which serve as the axis, and can tilt or rotate a predetermined angle about the second ball members which serve as the axis, thereby performing hand shake compensation operation.
[0352] Although at least a portion of extension 217 is Figure 12c The image shows the extension portion located in the opening 60A of the tilt guide unit 60. However, in another embodiment, the extension portion may be located outside the tilt guide unit 60, rather than in the center of the lower surface of the sensor base 270. In other words, in another embodiment, at least a portion of the extension portion of the sensor base may be located outside the opening 60A of the tilt guide unit 60, and an elastic member may be located at a position corresponding to the extension portion of the sensor base 270 and connected to the extension portion.
[0353] Reference Figure 13a When viewed from above, the first magnet unit 310A can overlap with the bosses 65A and 65B of the tilting guide unit 60 in the direction in which the bosses 65A and 65B face each other or in the direction of the first axis. Additionally, the second magnet unit 310B can overlap with the bosses 66A and 66B of the tilting guide unit 60 in the direction in which the bosses 66A and 66B face each other or in the direction of the second axis.
[0354] Reference Figure 4e and Figure 4f The tilting guide unit 60 can overlap with the magnet 310 in a direction perpendicular to the optical axis. For example, the first magnet unit 310A can overlap with the tilting guide unit 60 in the first axial direction, and the second magnet unit 310B can overlap with the tilting guide unit 60 in the second axial direction.
[0355] For example, magnet 310 and yoke 380 can be positioned below image sensor 810. For example, magnet 310 can be positioned below filter 610. Additionally, magnet 310 can be positioned below elastic member 30. For example, magnet 310 can be positioned lower than holder 140. For example, magnet 310 can be positioned below sensor base 270. For example, the upper surface of magnet 310 can be positioned lower than the lower surface of sensor base 270. The upper surface of magnet 310 can be positioned lower than the lower surface of holder 140. The upper surface of magnet 310 can be positioned lower than the lower surface of elastic member 30. For example, magnet 310 can be positioned lower than rolling member 21.
[0356] Reference Figure 4f For example, the upper surface of magnet 310, such as the upper surfaces of magnet units 310A and 310B, may be positioned lower than the top end of elastic member 30. In another embodiment, the upper surface of magnet 310 may be positioned higher than the top end of elastic member 30, or may be positioned at the same height as the top end of elastic member 30.
[0357] For example, the upper surface of magnet 310, such as the upper surface of magnet units 310A and 310B, can be positioned higher than the lowest end of elastic member 30. For example, the lowest end of elastic member 30 can be positioned lower than the lower surface of magnet 310, such as the lower surface of magnet units 310A and 310B. In another embodiment, the lowest end of elastic member 30 can be positioned higher than the lower surface of magnet 310, such as the lower surface of magnet units 310A and 310B. In another embodiment, the lowest end of elastic member 30 and the lower surface of magnet units 310A and 310B can be positioned at the same height.
[0358] Reference Figure 10b For example, the first magnet unit 310A and the second magnet unit 310B can have the same shape and size. The first length L1 of the first magnet unit 310A in the second axial direction can be less than the second length L2 of the first magnet unit 310A in the first axial direction. In addition, the first length of the second magnet unit 310B in the first axial direction can be less than the second length of the second magnet unit 310B in the second axial direction.
[0359] The length of the first magnet unit 310A in the optical axis direction can be less than the second length L2 of the first magnet unit 310A. Similarly, the length of the second magnet unit 310B in the optical axis direction can be less than the second length of the second magnet unit 310B. In another embodiment, the length of the first magnet unit 310A (or the second magnet unit 310B) in the optical axis direction can be equal to or greater than the second length L2 of the first magnet unit 310A (or the second magnet unit 310B).
[0360] For example, the first length L1 of the first magnet unit 310A (or the second magnet unit 310B) may be less than the length of the tilting guide unit 60 in the second direction (X-axis direction) or the third direction (Y-axis direction). For example, the first length L1 of the first magnet unit 310A (or the second magnet unit 310B) may be greater than the length M1 between the outer peripheral surface and the inner peripheral surface of the tilting guide unit 60. For example, M1 may be the shortest distance between the outer surface of the tilting guide unit 60 and the opening 60A in the tilting guide unit 60. In another embodiment, L1 may be equal to or less than M1.
[0361] For example, the first length L1 of the first magnet unit 310A (or the second magnet unit 310B) may be less than the length of the opening 60A in the tilting guide unit 60 in the first axial direction or the second axial direction. The first length L1 of the first magnet unit 310A (or the second magnet unit 310B) may be less than the length of the opening 60A in the second direction or the third direction. In another embodiment, L1 may be greater than or equal to the length of the opening 60A in the first axial direction or the second axial direction. Alternatively, L1 may be greater than or equal to the length of the opening 60A in the second direction or the third direction.
[0362] The shortest distance L3 between the first bosses 65A and 65B can be greater than the first length L1. The shortest distance L4 between the second bosses 66A and 66B can be greater than the first length L1. For example, L3 and L4 can be equal to each other. In another embodiment, L3 and L4 can be different from each other. The description of L3 and L4 can be applied or similarly applied to... Figure 9c and Figure 9d The first ball components 65A1 and 65B1 and the second ball components 66A1 and 66B1 are shown in the figure.
[0363] For example, the upper surface of magnet 310 may be positioned lower than the upper surface of the lower portion 42 of housing 210. This ensures sufficient space to avoid spatial interference between magnet 310 and the lower surface of sensor base 270. In another embodiment, the upper surface of magnet 310 and the upper surface of the lower portion 310 of housing 210 may be flush with each other. In another embodiment, the upper surface of magnet 310 may be positioned higher than the upper surface of the lower portion 420 of housing 210. For example, the upper surface of magnet 310 may be positioned lower than the highest point of the first protrusion 65 of tilting guide unit 60.
[0364] When viewed from above or along the optical axis, bosses 65A and 65B, elastic member 30, and first magnet unit 310A can overlap each other in the direction of the first axis. When viewed from above or along the optical axis, bosses 66A and 66B, elastic member 30, and second magnet unit 310B can overlap each other in the direction of the second axis.
[0365] When viewed from above or along the optical axis, the magnet 310 may not overlap with the elastic member 30 in the second direction (X-axis direction) or the third direction (Y-axis direction).
[0366] In another embodiment, when viewed from above or along the optical axis, the magnet 310 may overlap with the elastic member 30 in a second direction (X-axis direction) or a third direction (Y-axis direction).
[0367] Reference Figure 10c and Figure 11d The camera device may include a shielding member 390 that closes the opening 18 in the housing 210. The shielding member 390 may be disposed on the lower surface of the housing 210. The shielding member 390 may be coupled to or attached to the lower surface of the lower portion 42 of the housing 210.
[0368] The shielding member 390 may be attached to the housing 210 via an adhesive (not shown). The shielding member 390 may be attached to the receiving portion 49 of the housing 210 via an adhesive. The shielding member 390 may be spaced apart from the elastic member 30. For example, the shielding member 390 may be spaced apart from the second connecting portion 32 of the elastic member 390. The shielding member 390 may be opposite to or overlap with the elastic member 30 in the optical axis direction.
[0369] The receiving portion 49 may include at least one protrusion 44 projecting from its bottom surface 49A. A shielding member 390 may be disposed on the lower surface of the protrusion 44. An adhesive may be disposed on the lower surface of the protrusion 44, and the shielding member 390 may be attached to the lower surface of the protrusion 44 via the adhesive. At least one boss 6A may be disposed on the lower surface of the protrusion 44. A groove 79B may be formed in the lower surface of the protrusion 44 to facilitate the flow of the adhesive. Additionally, the groove 79B may inhibit the introduction of adhesive into the opening 60A of the housing 210. The shielding member 49 may include a through-hole 9A configured to engage with the lower surface of the protrusion 44. In another embodiment, the through-hole 9A may be a recess or a hole.
[0370] For example, the lower surface of the housing 210 may include a first surface 210A, a second surface stepped relative to the first surface 210A, and a third surface 49A stepped relative to the second surface. The second surface of the lower surface of the housing 210 may be the upper surface of the protrusion 44. When the camera device 200 is viewed from above, the second surface (the lower surface of the protrusion 44) may be positioned higher than the first surface 210A, and the third surface 49A may be positioned higher than the second surface. The second connecting portion 32 may be disposed on or connected to the third surface 49A, and the shielding member 390 may be disposed on or connected to the second surface.
[0371] In another embodiment, the shielding member 390 may be an adhesive strip. For example, the shielding member 390 may be an injection-molded material or a metal material. The shielding member 390 may alternatively be referred to as a "cap," a "sealing member," or a "shielding strip." The shielding member 390 may be spaced apart from the resilient member 30.
[0372] The shielding member 390 can be used to prevent foreign objects from being introduced into the housing 210 through the opening 18 and to protect the extension 217 from impact.
[0373] Figure 13a The electromagnetic forces F1 and F2 generated by the interaction between magnet units 310A and 310B and coil units 230A and 230B are shown, and Figure 13b It shows that due to Figure 13a The movement of the OIS moving unit 100 is caused by electromagnetic force. Figure 13a The electromagnetic force is shown when each of the first magnet unit 310A and the second magnet unit 310B is a bipolar magnet with N and S poles.
[0374] Reference Figure 13a and Figure 13b The movement of the OIS moving unit is described by the OIS driving unit. The OIS driving unit may include a coil 230 and a magnet 310. Additionally, the OIS driving unit may include a position sensor 240. The AF driving unit may be represented by one of a "first driving unit" and a "second driving unit," and the OIS driving unit may be represented by the other of a "first driving unit" and a "second driving unit."
[0375] For example, the first surface (e.g., the upper surface) of the first magnet unit 310A facing or opposite to the first coil unit 230A in the optical axis direction, and the first surface (e.g., the upper surface) of the second magnet unit 310B facing or opposite to the second coil unit 230B in the optical axis direction, can have opposite polarities. Since the first surface (e.g., the upper surface) of the first magnet unit 310A and the first surface (e.g., the upper surface) of the second magnet unit 310B have opposite polarities, the influence of the magnetic field of the first magnet unit 310A on the second coil unit 230B and the influence of the magnetic field of the second magnet unit on the first coil unit 230A can be canceled, thereby achieving magnetic field balance. Therefore, the unwanted magnetic field influence on the coil units 230A and 230B caused by the two adjacent magnet units 310A and 310B can be suppressed or reduced, thereby improving the performance and reliability of the OIS operation of the camera device 200.
[0376] Furthermore, since the first surface (e.g., the upper surface) of the first magnet unit 310A and the first surface (e.g., the upper surface) of the second magnet unit 310B have opposite polarities, the influence of the magnetic field of the first magnet unit 310A on the second sensor 240B and the influence of the magnetic field of the second magnet unit on the first sensor 240A can be canceled, thereby achieving magnetic field balance. Therefore, the influence of unwanted magnetic fields caused by adjacent magnet units 310A and 310B on sensors 240A and 240B can be suppressed or reduced, thereby improving the reliability of the output of sensors 240A and 240B and improving the performance and reliability of OIS operation.
[0377] Additionally, for example, the second surface (e.g., the lower surface) of the first magnet unit 310A and the second surface (e.g., the lower surface) of the second magnet unit 310B may have opposite polarities. The second surface (e.g., the lower surface) of the first magnet unit 310A may be the opposite surface to the first surface (e.g., the upper surface) of the first magnet unit 310A, and may have a polarity opposite to that of the first surface (e.g., the upper surface) of the first magnet unit 310B. Similarly, the second surface (e.g., the lower surface) of the second magnet unit 310B may be the opposite surface to the first surface (e.g., the upper surface) of the second magnet unit 310B, and may have a polarity opposite to that of the first surface (e.g., the upper surface) of the second magnet unit 310B. For example, the first surface of the first magnet unit 310A may have an N pole (or an S pole), and the first surface of the second magnet unit 310B may have an S pole (or an N pole).
[0378] The first electromagnetic force F1 can be generated by the interaction between the first magnet unit 310A and the first coil unit 230A. For example, the first electromagnetic force F1 can be applied in the optical axis direction, such as the upward or downward direction. The OIS moving unit 100 can tilt about the second axis (or the second boss 66) by the first electromagnetic force F1. For example, the OIS moving unit 100 can tilt about the second axis by the first electromagnetic force F1. Here, tilting about the second axis means that the OIS moving unit tilts about the second axis or rotates about the second axis by a predetermined angle.
[0379] For example, the tilting guide unit 60 can be tilted about the second axis (or the bosses 66A and 66B of the second boss 66) by a first electromagnetic force F1. For example, the tilting guide unit 60 can be tilted about the second axis by the first electromagnetic force F1. For example, in an embodiment where the bosses 66A and 66B are arranged along the direction of the first axis, the tilting guide unit 60 can be tilted about the first axis.
[0380] Reference Figure 4b In order for the OIS moving unit to tilt about the second axis (or the second boss 66 of the tilting guide unit 60), a gap or space must exist between the tilting guide unit 60 and the OIS moving unit (e.g., the sensor base 270) via the first boss 65 of the tilting guide unit 60. For example, a gap or space may exist between the upper surface 6A of the tilting guide unit 60 and the OIS moving unit (e.g., the sensor base 270) in which the tilting guide unit 60 can move. For example, the upper surface 6A of the tilting guide unit 60 may be spaced apart from the OIS moving unit (e.g., the sensor base 270) or the lower surface of the sensor base 270.
[0381] The second electromagnetic force F2 can be generated by the interaction between the second magnet unit 310B and the second coil unit 230B. For example, the second electromagnetic force F2 can be applied in the upward or downward direction.
[0382] The OIS moving unit can be tilted about the first axis (or the first boss 65) by the second electromagnetic force F2. For example, the OIS moving unit can be tilted about the first axis by the second electromagnetic force F2. Here, tilting the first axis means that the OIS moving unit tilts about the first axis or rotates the OIS moving unit about the first axis by a predetermined angle.
[0383] For example, the tilting guide unit 60 can contact the fixed unit (e.g., housing 210) by tilting the first axis or the second axis. In this case, the fixed unit can be used as a stop configured to inhibit the tilting of the OIS moving unit.
[0384] Figure 13c It shows that according to Figure 13aThe modified magnet units 310A and 310B are configured. (Refer to...) Figure 13c The first surface (e.g., the upper surface) of the first magnet unit 310A facing or opposite to the first coil unit 230A in the optical axis direction, and the first surface (e.g., the upper surface) of the second magnet unit 310B facing or opposite to the second coil unit 230B in the optical axis direction, can have the same polarity. For example, each of the first surface of the first magnet unit 310A and the first surface of the second magnet unit 310B can have an N pole (or an S pole), and each of the second surface of the first magnet unit 310A and the second surface of the second magnet unit 310B can have an S pole (or an N pole).
[0385] Figure 13d This is a view illustrating electromagnetic forces F11 and F12 generated by the interaction between magnet units 310A1 and 310B1 and coil units 230A and 230B according to another embodiment.
[0386] Reference Figure 13d The first magnet unit 310A1 may be a magnet having N poles and S poles separated or arranged in the direction of the first axis. The second magnet unit 310B1 may be a magnet having N poles and S poles separated or arranged in the direction of the second axis. For example, the first surface of the first magnet unit 310A1 may include N poles and S poles, and the first surface of the second magnet unit 310B1 may include N poles and S poles.
[0387] The first electromagnetic force F11 generated by the interaction between the first magnet unit 310A1 and the first coil unit 230A can act in a direction different from the optical axis (e.g., the direction of the first axis). The second electromagnetic force F12 generated by the interaction between the second magnet unit 310B1 and the second coil unit 230 can act in a direction different from the optical axis (e.g., the direction of the second axis).
[0388] For example, the first electromagnetic force F11 generated by the interaction between the first magnet unit 310A1 and the first coil unit 230A can act in a direction perpendicular to the optical axis. Additionally, the second electromagnetic force F12 generated by the interaction between the second magnet unit 310B1 and the second coil unit 230B can act in a direction perpendicular to the optical axis. For example, F11 and F12 can act in directions that intersect each other (e.g., directions perpendicular to each other).
[0389] exist Figure 13dIn this embodiment, the first pole of the first magnet unit 310A1 can be positioned closer to the tilting guide unit 60 than the second pole of the first magnet unit 310A1. Similarly, the second pole of the second magnet unit 310B1 can be positioned closer to the tilting guide unit 60 than the first pole of the second magnet unit 310B1. Alternatively, the first pole of the first magnet unit 310A1 can be located internally, and the second pole of the first magnet unit 310A1 can be located externally. Conversely, the first pole of the second magnet unit 310B1 can be located externally, and the second pole of the second magnet unit 310B1 can be located internally. For example, the first pole can be an N pole (or an S pole), and the second pole can be an S pole (or an N pole). In another embodiment, the first magnet unit 310A1 and the second magnet unit 310B1 can be positioned such that their opposite polarities are close to the tilting guide unit 60. Figure 13a The description of the magnetic field balance in the implementation method can be applied or similarly applied to Figure 13d The implementation method.
[0390] In another embodiment, the first magnet unit 310A1 and the second magnet unit 310B1 may be configured such that the same polarity (e.g., N pole or S pole) is close to the tilting guide unit 60.
[0391] The OIS moving unit can be tilted about the second axis (or the second boss 66) by the first electromagnetic force F11. For example, the OIS moving unit can be tilted about the second axis by the first electromagnetic force F11. The OIS moving unit can be tilted about the first axis (or the first boss 65) by the second electromagnetic force F12. For example, the OIS moving unit can be tilted about the first axis by the second electromagnetic force F12.
[0392] exist Figure 13a , Figure 13c and Figure 13d In the middle, the magnetic yoke 380 can be used to increase the electromagnetic forces F1, F2, F11 and F12 (or driving force).
[0393] exist Figures 13a to 13d In this embodiment, the OIS moving unit can be tilted diagonally about a first or second axis via magnet units 310A and 310B, coil units 230A and 230B, and tilting guide unit 60. In another embodiment, the arrangement of magnet units 310A and 310B and coil units 230A and 230B, as well as the axis arrangement caused by the bosses 65 and 66 of the tilting guide unit, can be changed to achieve X-axis tilting or Y-axis tilting.
[0394] In a camera device configured such that the image sensor is fixed and the lens is moved in a direction perpendicular to the optical axis for shake compensation or image shake compensation (“Comparative Example 1”), image distortion may occur. Furthermore, in a camera device configured such that the lens is fixed and the image sensor is moved or tilted for shake compensation or image shake compensation (“Comparative Example 2”), image distortion may occur at the edges or corners of the image sensor. Therefore, in Comparative Example 1 and Comparative Example 2, the image sensor and lens are separate, and only one of the image sensor and lens is moved or tilted, which may cause image distortion during shake compensation, and shake compensation at wide angles may be difficult.
[0395] In one embodiment, for shaky hand compensation, the OIS driving unit can tilt the OIS moving unit 100 about a first axis or a second axis, or can rotate the OIS moving unit within a predetermined angle range. In another embodiment, since the OIS moving unit 100 includes a lens module 400 and an image sensor 810, when OIS is performed, the tilt direction (or rotation direction) and tilt angle (or rotation angle) of the lens module 400 (e.g., a lens or lens barrel) (or spool 110) can be the same as or approximately the same as the tilt direction (or rotation direction) and tilt angle (or rotation angle) of the image sensor 810.
[0396] In this implementation, when OIS is performed, the lens module 400 (or spool 110) and the image sensor 810 can tilt simultaneously or rotate together, thereby obtaining 100% image resolution without image distortion, and hand shake compensation or shakiness compensation at wide angles is possible.
[0397] Furthermore, in this embodiment, since the OIS moving unit, including the lens module 400 (or spool 110) and the image sensor 810, tilts or rotates, image degradation does not occur in the central region or peripheral region of the image sensor (e.g., corners or corner areas of the image sensor) even if camera shake occurs. Therefore, broadband shake compensation is possible in this embodiment. Moreover, since distortion-free image compensation is mechanically possible in this embodiment, the load during image processing is low compared to Comparative Example 1 and Comparative Example 2, thereby reducing current consumption.
[0398] Furthermore, in the implementation, since the tilting guide unit 60 is used to tilt the OIS moving unit, the OIS moving unit can tilt stably, precisely and accurately compared to examples that only use ball members or shaft members, thereby improving the reliability of OIS operation.
[0399] Furthermore, in the implementation, the power consumption required to perform OIS can be reduced by the bent portions 804D and 804E of the circuit board 800 and the third portion 804C of the fourth substrate 804, which is a flexible substrate.
[0400] Furthermore, in the embodiment, since the tilt guide unit 60 is disposed in the sitting portion 69 of the housing 210, and the connecting portion 49 of the housing 210 overlaps with the opening 60A in the tilt guide unit 60, the height or length of the camera device 200 in the optical axis direction can be reduced.
[0401] Furthermore, in the embodiment, since at least a portion of the elastic member 30 is disposed in the opening 60A in the tilting guide unit 60, the restoring force of the elastic member 30 can be reduced, which can increase the holding force or retaining force required to support the OIS moving unit, thereby enabling stable OIS operation.
[0402] Furthermore, in the embodiment, since the first magnet unit 310A and the second magnet unit 310B, which serve as driving magnets for shakiness compensation, are disposed on the lower portion 42 of the housing 210 instead of on the side portions 71A to 71D of the housing 210, the thickness of the side portions 71A to 71D of the housing 210 (or the length of the side portions 71A to 71D of the housing 210 in the direction perpendicular to the optical axis) can be reduced, thereby enabling the large-aperture lens to be mounted to the camera device.
[0403] In a comparative embodiment using a magnetic material that applies attractive or repulsive forces to achieve a holding or retaining force for supporting the OIS moving unit relative to a fixed unit, magnetic field interference can occur between the magnetic material 130 and the driving magnet 310. In this comparative embodiment, the desired stable holding force may not be obtained due to the magnetic field interference. Furthermore, the accuracy or reliability of AF operation may deteriorate due to the magnetic field interference, and the accuracy of OIS operation reliability for shaky hand compensation may also deteriorate.
[0404] In this embodiment, an elastic member 30 configured to generate a holding force is used. Because the restoring force FR of the elastic member 30 is used to generate the holding force, magnetic field interference between the magnetic material and the drive magnet 130 or 310 used to generate the holding force can be prevented, and a stable holding force can be obtained as desired. Therefore, this embodiment allows for stable OIS driving.
[0405] Compared to the comparative embodiment, since the elastic member 30 according to the embodiment can obtain a stable holding force, the linearity of the tilt angle (or displacement of the OIS moving unit) during OIS driving is excellent, and it is suitable for open-loop OIS driving in which the position sensor is omitted. Therefore, in the embodiment, reliable and excellent open-loop OIS driving can be achieved even without the position sensor 240.
[0406] Furthermore, due to the use of the elastic member 30, the axis used for module tilting can be easily and freely selected in the embodiment, and a linear holding force can be achieved relative to the stroke (or displacement) of the OIS moving unit. For example, in the embodiment, the design can facilitate the use of at least one of a first axis, a second axis, an X-axis, or a Y-axis for module tilting.
[0407] Figure 14 This is a perspective view of a camera device 200 including a lens module 400.
[0408] Reference Figure 14 The lens module 400 can be coupled to the spool 100 and can move together with the spool 110 along the optical axis. For example, the lens module 400 may include at least one of a lens or a lens barrel. In an embodiment, the lens module 400 and the image sensor 810 can simultaneously tilt along a first axis or a second axis in the same direction and at the same angle during hand shake compensation or shake compensation.
[0409] Figure 15a The thrusts PR1 and PR2 acting on the tilting guide unit 60 due to the restoring force FR of the elastic member 30 are shown. Figure 15b The first position of the OIS moving unit 100 is shown, and Figure 15c The second position of the OIS moving unit 100 is shown. Figure 15b The initial position of the OIS moving unit is shown without a drive signal being supplied to coil 230.
[0410] Reference Figure 15aThe first connecting portion 31 of the elastic member 30 can be connected to the OIS moving unit (e.g., sensor base 270), and the second connecting portion 32 of the elastic member 30 can be connected to the fixed unit (e.g., housing 210). Due to the restoring force FR of the elastic member 30, the OIS moving unit (e.g., sensor base 270) can be pulled toward the fixed unit (e.g., housing 201). The restoring force FR generates a thrust PR1 that causes the OIS moving unit (e.g., sensor base 270) to push the bosses 65A and 65B of the tilting guide unit 60. Therefore, the thrust PR1 can cause the bosses 65A and 65B of the tilting guide unit 60 to contact or closely contact the OIS moving unit (e.g., sensor base 270).
[0411] Additionally, by means of the restoring force FR, a thrust PR2 can be generated that causes the fixing unit (e.g., housing 210) to push the bosses 66A and 66B of the tilting guide unit 60. Therefore, the thrust PR2 can cause the bosses 66A and 66B of the tilting guide unit 60 to contact or closely contact the fixing unit (e.g., housing 210).
[0412] In other words, the bosses 65A and 65B of the tilting guide unit 60 are maintained in contact with the OIS moving unit by means of the thrust PR1, and the bosses 65A and 65B of the tilting guide unit 60 can be maintained in contact with the fixed unit by means of the thrust PR2. Tilting movement can be performed while the bosses are in contact with the OIS moving unit and the fixed unit.
[0413] Reference Figure 15b and Figure 15c The OIS moving unit 100 can tilt around the second axis at a predetermined angle θ1 by the force F1 caused by the interaction between the first magnet unit 310A and the first coil unit 230A. That is, when the OIS moving unit 100 moves from the first position to the second position, both the image sensor 810 and the lens module 400 can tilt simultaneously by the predetermined angle θ1. Furthermore, when the OIS moving unit 100 moves from the first position to the second position, the tilting guide unit 60 can tilt together with the image sensor 810 and the lens module 400 by the predetermined angle θ1.
[0414] Figure 15d The third position of the OIS moving unit 100 is shown.
[0415] Reference Figure 15dThe OIS moving unit 100 can tilt around the first axis by a predetermined angle θ2 due to the force F2 caused by the interaction between the second magnet unit 310B and the second coil unit 230B. For example, when the OIS moving unit 100 moves from the first position to the third position, the image sensor 810 and the lens module 400 can tilt simultaneously by the predetermined angle θ2.
[0416] The image sensor 810 and the lens module 400 are simultaneously tilted about a first axis or a second axis by force F1 or force F2. Therefore, in this embodiment, 100% image resolution can be obtained without image distortion, and hand shake compensation or shake compensation can be performed at wide angles.
[0417] For example, when viewed from above or along the optical axis, the first axis can be the first diagonal direction of the OIS moving unit 100, and the second axis can be the second diagonal direction of the OIS moving unit 100. For example, the first diagonal direction of the OIS moving unit can be the first diagonal direction of any one of the holder 140, the sensor base 270, and the first substrate 801 of the circuit board 800. Similarly, the second diagonal direction of the OIS moving unit can be the second diagonal direction of any one of the holder 140, the sensor base 270, and the first substrate 801 of the circuit board 800.
[0418] In another embodiment, when viewed from above or along the optical axis, the first axis can be the first diagonal direction of the fixing unit, and the second axis can be the second diagonal direction of the fixing unit. For example, the first diagonal direction of the fixing unit can be the first diagonal direction of the housing 210 or the cover member 300. Additionally, the second diagonal direction of the fixing unit can be the second diagonal direction of the housing 210 or the cover member 300.
[0419] For example, the first diagonal direction of the OIS moving unit 100 (or fixed unit) can be a direction intersecting with a second direction (e.g., the X-axis direction) or a third direction, and the second diagonal direction of the OIS moving unit 100 (or fixed unit) can be a direction intersecting with a second direction (e.g., the X-axis direction) or a third direction. The first diagonal direction and the second diagonal direction of the OIS moving unit 100 can intersect each other. For example, the first diagonal direction and the second diagonal direction of the OIS moving unit 100 can be perpendicular to each other.
[0420] In another embodiment, the first axis may be the first horizontal direction of the OIS moving unit 100 (or fixed unit), and the second axis may be the second horizontal direction of the OIS moving unit 100 (or fixed unit).
[0421] Furthermore, the camera device 200 according to the embodiments may be included in an optical instrument for the purpose of forming an image of an object existing in space using reflection, refraction, absorption, interference, and diffraction as properties of light, for increasing visibility, for recording and reproducing images using a lens, or for optical measurement or image propagation or transmission. For example, the optical instrument according to the embodiments may be a cellular phone, mobile phone, smartphone, portable smart device, digital camera, laptop computer, digital broadcast terminal, personal digital assistant (PDA), portable multimedia player (PMP), navigation device, etc., but is not limited thereto, and may also be any device used for capturing images or pictures.
