Description

TECHNICAL FIELD

[0001] Embodiments relate to a lens moving device, a camera module including the same, and an optical apparatus. BACKGROUND

[0002] The voice coil motor (VCM) technology used in existing general camera modules is difficult to apply to micro-sized camera modules intended to present low power consumption, and related research has been actively conducted.

[0003] The demand for and production of electronic products such as smartphones and camera-equipped phones are increasing. The camera resolution of the phone is increasing and the size is decreasing, and accordingly, the actuator thereof is becoming smaller, larger in diameter, and multifunctional. In order to implement a high-resolution phone camera, performance improvement of the phone camera and additional functions such as auto focus, shutter shake improvement, zoom function, etc. are also required.

[0004] In addition, due to the increasing demand for functionality enhancement and high resolution of the phone, the size of the image sensor and the aperture of the lens installed on the camera module are increasing. Due to the increase in the lens aperture, when the phone is vibrated and impacted, the stress received by the OIS wire included in the voice coil motor of the camera module increases, causing the OIS wire to deform and break, and thus causing a running failure or degradation of the oscillation of the OIS of the camera module. SUMMARY

[0072] The lens moving device according to the embodiment can perform an "autofocus function". Here, the "autofocus function" is used to automatically focus the image of the subject onto the surface of the image sensor.

[0073] Furthermore, the lens moving device according to the embodiment can perform a "shake correction function". Here, the "shake correction function" can be used to prevent the outline of the captured image from becoming blurred due to vibrations caused by the user's hand tremors when capturing still images.

[0074] Figure 1 This is an exploded perspective view of the lens moving device 100 according to an embodiment. Figure 2 It is Figure 1 The image shows a perspective view of the lens moving device 100 after the cover member 300 has been removed, after assembly.

[0075] Reference Figure 1 and Figure 2 The lens moving device 100 includes a coil 110, a first coil 120, a first magnet 130, a housing 140, an upper elastic member 150, a lower elastic member 160, a base 210, a support member 220, a second coil 230, and a circuit board 250.

[0076] In addition, to implement AF feedback, the lens moving device 100 may also include a first position sensor 170, a circuit board 190, and a second magnet 180. The circuit board 250 may be referred to as the "first circuit board", and the circuit board 190 may be referred to as the "second circuit board".

[0077] To perform the hand shake correction function, the lens moving device 100 may also include a second position sensor 240.

[0078] In addition, the lens moving device 100 may also include a third magnet 185 and a cover member 300.

[0079] In addition, the lens moving device 100 may also include a capacitor 195 mounted on a circuit board 190.

[0080] First, the spool 110 will be described.

[0081] The spool 110 can be disposed in the housing 140 so that it is movable in the optical axis OA direction or a first direction (e.g., the Z-axis direction) by means of the electromagnetic interaction between the first coil 120 and the first magnet 130.

[0082] Figure 3a yes Figure 1 The perspective view of the spool 110, the second magnet 180, and the third magnet 185 shown. Figure 3b The first coil 120 connected to the spool 110 is shown.

[0083] Reference Figure 3a and 3b The spool 110 may have an opening for mounting a lens or lens barrel. In one example, the opening of the spool 110 may be a through hole extending through the spool 110 along the optical axis, and may be circular, elliptical, or polygonal, but is not limited thereto.

[0084] The lens can be directly mounted in the opening in the tube 110, but the invention is not limited thereto. In another embodiment, the tube to which at least one lens is mounted or connected can be connected to or mounted in the opening in the tube 110. The lens or tube can be connected to the inner circumferential surface of the tube 110 in any various manner.

[0085] The spool 110 may include first side portions 110b-1 spaced apart from each other and second side portions 110b-2 spaced apart from each other. Each second side portion 110b-2 may connect two adjacent first side portions 110b-1 to each other. In one example, the horizontal or lateral length of each of the first side portions 110b-1 of the spool 110 may be different from the horizontal or lateral length of each of the second side portions 110b-2. In one example, the horizontal length of each of the first side portions 110b-1 may be longer than the horizontal length of each of the second side portions 110b-2, but the invention is not limited thereto. In another embodiment, the former may be equal to or shorter than the latter.

[0086] The spool 110 may include a protrusion 115 disposed on its outer surface.

[0087] In one example, the protrusion 115 may be provided on the outer surface of each of the second side portions 110b-2 of the bobbin 110, but the invention is not limited thereto. The protrusion 115 may protrude in a direction parallel to a line extending through the center of the opening in the bobbin 110 and perpendicular to the optical axis, but the invention is not limited thereto.

[0088] The protrusion 115 of the spool 110 can correspond to the groove 25a in the housing 140, and can be inserted into or disposed in the groove 25a in the housing 140 in order to minimize or prevent the rotation of the spool 110 about the optical axis from exceeding a predetermined range.

[0089] Furthermore, when the spool 110 moves beyond a predetermined range in the optical axis direction (e.g., from the upper elastic member 150 to the lower elastic member 160) due to external impacts, the protrusion 115 can be used as a stop to minimize or prevent direct collision between the lower surface of the spool 110 and the base 210, the second coil 230, or the circuit board 250.

[0090] The spool 110 may have a first escape groove 112a formed in its upper surface to avoid spatial interference with the first frame connection portion 153 of the upper elastic member 150. In one example, the first escape groove 112a may be provided in each of the second sides 110b-2 of the spool 110, but the invention is not limited thereto.

[0091] The spool 110 may have a guide portion 111 on its upper surface to guide the upper elastic member 150 to the installation position. For example... Figure 3a As shown, in one example, the guide portion 111 of the spool 110 may be disposed in the first escape groove 112a to guide the frame connection portion 153 of the upper elastic member 150 to extend along a predetermined path. In one example, the guide portion 111 may protrude from the bottom surface of the first escape groove 112a in the optical axis direction.

[0092] In addition, dampers (refer to) Figure 11 The DA5 can be disposed between the guide portion 111 and the first frame connection portion 153 of the upper elastic member 150.

[0093] The spool 110 may include a stop 116 protruding from its upper surface.

[0094] When the spool 110 moves beyond the specified range due to external impact or other reasons while moving in the first direction to perform the autofocus function, the stop 116 of the spool 110 can be used to prevent the upper surface of the spool 110 from directly colliding with the inner side of the upper plate of the cover member 300.

[0095] To connect and secure the spool 110 to the upper elastic member 150, the spool 110 may include a first connecting portion 113 formed thereon on its upper portion or upper surface. In one example, in Figure 3a In the diagram, the first connecting portion 113 of the spool 110 is shown as a protrusion, but the invention is not limited thereto. In another embodiment, the first connecting portion 113 of the spool 110 may be formed as a groove or a plane.

[0096] Furthermore, in order to connect and secure the spool 110 to the lower elastic member 160, the spool 110 may include a second connecting portion 117 formed thereon on its lower portion or lower surface. Figure 3b In the diagram, the second connecting portion 117 of the spool 110 is shown as a protrusion, but the invention is not limited thereto. In another embodiment, the second connecting portion 117 of the spool 110 may be formed as a groove or a flat surface.

[0097] The spool 110 may have a placement groove 105 formed in its outer surface to allow the first coil 120 to be placed, inserted, or disposed therein. The placement groove 105 may be recessed from the outer surface of each of the first side portion 110b-1 and the second side portion 110b-2 of the spool 110 and may have a closed curve shape (e.g., annular) that conforms to the shape of the first coil 120.

[0098] Additionally, to prevent the coil 120 from separating when it is connected to the lower elastic members 160-1 and 160-2, and to guide the two ends of the coil 120, guide grooves 116a and 116b can be formed in two of the sides 110b-1 and 110b-2 of the bobbin 110. In one example, guide grooves 116a and 116b can be formed in the lower surface of the two first sides 110b-1 of the bobbin 110 at opposite positions, or in the lower surface of the two second sides 110b-2 of the bobbin 110 at opposite positions.

[0099] In addition, the spool 110 may have a mounting groove 180a formed in its outer surface to allow the second magnet 180 to be mounted, inserted, fixed or set therein.

[0100] The placement groove 180a in the spool 110 may be recessed from the outer surface of the spool 110 and may include, but is not limited to, an opening formed in at least one of the upper and lower surfaces of the spool 110.

[0101] In addition, the spool 110 may have a mounting groove 185a formed in its outer surface to allow the third magnet 185 to be mounted, inserted, fixed or set therein.

[0102] The placement groove 185a in the spool 110 may be recessed from the outer surface of the spool 110 and may have an opening formed in at least one of the upper and lower surfaces of the spool 110, but is not limited thereto.

[0103] Each of the placement slots 180a and 185a in the coil 110 may be located above the placement slot 105 where the first coil 120 is disposed, and may be connected to or continuous with the placement slot 105, but is not limited thereto. In another embodiment, the two placement slots may be spaced apart from each other.

[0104] The placement groove 180a in the spool 110 can be formed in one of the first side portions 110b-1 of the spool 110, and the placement groove 185a in the spool 110 can be formed in the other of the first side portions 110b-2 of the spool 110.

[0105] In one example, the placement slots 180a and 185a may be formed in two first sides of the line cylinder 110 that face each other or are opposite to each other.

[0106] Because the second magnet 180 and the third magnet 185 are disposed in the mounting slots 180a and 185a in the two first sides of the tube 110 at opposite positions, the weight balance of the second magnet 180 and the third magnet 185 can be achieved, and the influence on the AF driving force caused by the magnetic field interference between the first magnet 130 and the second magnet 180 can be canceled out by the influence on the AF driving force caused by the magnetic field interference between the first magnet 130 and the third magnet 185, thereby improving the accuracy of autofocus (AF) operation.

[0107] The spool 110 may have threads 11 on its inner circumferential surface for connection to a lens or lens barrel. The threads 11 are formed on the inner circumferential surface of the spool 110 while it is held in place by clamps or the like. The spool 110 may have clamping grooves 15a and 15b formed in its upper surface. In one example, the clamping grooves 15a and 15b may be formed in the upper surface of two first sides 110b-1 or two second sides 110b-1 at opposite positions on the spool 110, but the invention is not limited thereto. The clamping grooves 15a and 15b can also be used as foreign object collectors for collecting foreign objects.

[0108] Next, the first coil 120 will be described.

[0109] The first coil 120 is disposed on the spool 110. In one example, the first coil 120 may be disposed on the outer surface of the spool 110. In another example, the first coil 120 may move together with the spool 110 in the optical axis direction.

[0110] The first coil 120 may be disposed below the second magnet 180 and the third magnet 185, but the invention is not limited thereto. In one example, the first coil 120 may be disposed below the protrusion 115 of the tube 110, but the invention is not limited thereto.

[0111] In one example, the first coil 120 may not overlap with the second magnet 180 and the third magnet 185 in a direction perpendicular to the optical axis, but the invention is not limited thereto. In another embodiment, the first coil may overlap with at least a portion of each of the second magnet 180 and the third magnet 185 in a direction perpendicular to the optical axis.

[0112] In one example, a first coil 120 may be disposed in a mounting slot 105 in a coil 110, a second magnet 180 may be inserted into or disposed in a mounting slot 180a in a coil 110, and a third magnet 185 may be inserted into or disposed in a mounting slot 185a in a coil 110. The first magnet 180 and the second magnet 185 may be disposed inside the first coil 120.

[0113] Each of the second magnet 180 and the third magnet 185 disposed on the spool 110 may be spaced apart from the first coil 120 in the direction of the optical axis OA, but the invention is not limited thereto. In another embodiment, each of the second magnet 180 and the third magnet 185 disposed on the spool 110 may contact the first coil 120, or overlap a portion of the first coil 120 in a direction perpendicular to the optical axis.

[0114] The first coil 120 may be wound around the outer surface of the bobbin 110 in the winding direction about the optical axis OA. In one example, the first coil 120 may have the shape of a closed curve around the outer surface of the bobbin 110, such as a ring.

[0115] The first coil 120 can be directly wound around the outer surface of the spool 110, but the present invention is not limited thereto. In another embodiment, the first coil 120 can be wound around the spool 110 using a coil loop, or it can be implemented as a coil block with an angled ring.

[0116] Power or a drive signal can be supplied to the first coil 120. The power or drive signal supplied to the first coil 120 can be a DC signal or an AC signal, or a signal that includes both DC and AC components, and can be voltage-type or current-type.

[0117] When a drive signal (e.g., drive current) is provided to the first coil 120, an electromagnetic force can be generated through electromagnetic interaction with the first magnet 130, and the coil 110 can move in the direction of the optical axis (OA) by the generated electromagnetic force.

[0118] At the initial position of the AF operating unit, the spool 110 can move up or down, which is called the bidirectional drive of the AF operating unit.

[0119] Alternatively, at the initial position of the AF operating unit, the spool 110 can move upwards, which is referred to as the unidirectional drive of the AF operating unit.

[0120] At the initial position of the AF operation unit, the first coil 120 can be configured to correspond to or overlap with the first magnet 130 disposed in the housing 140 in a direction parallel to a line extending through the optical axis OA perpendicular to it.

[0121] In one example, the AF operating unit may include a spool 110 and components connected to the spool 110 (e.g., a first coil 120, a second magnet 180, and a third magnet 185). The AF operating unit may further include a lens or lens barrel connected to the spool 110.

[0122] The initial position of the AF operating unit can be the original position of the AF operating unit when no power is applied to the first coil 1120, or the position of the AF operating unit caused by the elastic deformation of the upper elastic member 150 and the lower elastic member 160 due to the weight of the AF operating unit.

[0123] In addition, the initial position of the spool 110 can be the position of the AF operating unit when gravity acts in the direction from the spool 110 to the base 210 or when gravity acts in the direction from the base 210 to the spool 110.

[0124] Next, the second magnet 180 and the third magnet 185 will be described.

[0125] Because the second magnet 180 provides the magnetic field detected by the first position sensor 170, the second magnet 180 can be called a "sensing magnet", and because the third magnet 185 eliminates the influence of the magnetic field of the sensing magnet 180 and establishes a weight balance with the sensing magnet 180, the third magnet 185 can be called a "balancing magnet".

[0126] The second magnet 180 can be disposed in the mounting slot 180a in the spool 110, thereby facing the first position sensor 170. In one example, at the initial position of the spool 110, the second magnet 180 may overlap with the first position sensor 170 in a direction parallel to a line perpendicular to and extending through the optical axis, but the invention is not limited thereto. In another embodiment, at the initial position of the spool 110, the second magnet 180 and the first position sensor 170 may not overlap each other in a direction parallel to a line perpendicular to and extending through the optical axis.

[0127] The second magnet 180 facing the first position sensor 170 may be exposed from the mounting groove 180a at a portion of one of its surfaces, but the invention is not limited thereto. In another embodiment, the second magnet 180 facing the first position sensor 170 may not be exposed from the mounting groove 180a at a portion of one of its surfaces.

[0128] In one example, each of the second magnet 180 and the third magnet 185 may be a bipolar magnet or a quadrupole magnet comprising two N poles and two S poles.

[0129] Each of the second magnet 180 and the third magnet 185 may include a first magnet portion 17a, a second magnet portion 17b, and a partition wall 17c disposed between the first magnet portion 17a and the second magnet portion 17b. Here, the partition wall 17c may be referred to as a "non-magnetic partition wall".

[0130] The first magnet portion 17a may include an N pole, a S pole, and a first interface portion between the N pole and the S pole. The first interface portion may be a portion of a region that is substantially non-magnetic and has almost no polarity, and may be a portion that is naturally formed to form a magnet consisting of an N pole and an S pole.

[0131] The second magnet portion 17b may include an N pole, a S pole, and a second interface portion between the N pole and the S pole. The second interface portion may be a portion that is substantially non-magnetic and has a nearly non-polar region, and may be a portion that is naturally formed to form a magnet consisting of an N pole and an S pole.

[0132] The partition wall 17c can separate or isolate the first magnet portion 17a and the second magnet portion 17b, and can be a substantially non-magnetic or polarized portion. In one example, the partition wall can be a non-magnetic material, air, etc. The non-magnetic partition wall can be referred to as a "neutral region" or "neutral segment".

[0133] The partition wall 17c can be an artificially formed portion when the first magnet portion 17a and the second magnet portion 17b are magnetized, and the width of the partition wall 17c can be larger than the width of the first interface portion (or the width of the second interface portion). Here, the width of the partition wall 17c can be the length of the partition wall 17c in the direction from the first magnet portion 17a to the second magnet portion 17b. The width of the first interface portion (or the second interface portion) can be the length of the first interface portion in the direction from the N pole to the S pole of each of the first magnet portion 17a and the second magnet portion 17b.

[0134] In one example, the first magnet portion 17a and the second magnet portion 17b may be configured to face each other in the optical axis direction. In one example, the partition wall 17c may be parallel to a line perpendicular to the optical axis and extending through the optical axis.

[0135] In another embodiment, each of the second and third magnets may be a unipolar magnetized magnet having an N pole and an S pole.

[0136] In one example, each of the second magnet 180 and the third magnet 185 disposed on the tube 110 can be configured such that the interface between the N pole and the S pole is parallel to a direction perpendicular to the optical axis OA. In one example, the N pole and the S pole of each of the second magnet 180 and the third magnet 185 can face each other in the optical axis direction.

[0137] In one example, each surface of the second magnet 180 and the third magnet 185 facing the first position sensor 170 can be divided into N poles and S poles, but the invention is not limited thereto.

[0138] In another embodiment, for example, the interface between the N pole and the S pole of each of the second magnet 180 and the third magnet 185 disposed on the tube 110 can be parallel to the optical axis OA.

[0139] The second magnet 180 can move together with the bobbin 110 in the optical axis direction, and the first position sensor 170 can detect the magnetic field strength or magnetic force of the second magnet 180 moving in the optical axis direction, and can output an output signal corresponding to the detection result.

[0140] In one example, the magnetic field strength or magnetic force detected by the first position sensor 170 can change according to the displacement of the spool 110 in the optical axis direction. The first position sensor 170 can output an output signal proportional to the detected magnetic field strength, and the output signal from the first position sensor 170 can be used to detect the displacement of the spool 110 in the optical axis direction.

[0141] Next, the housing 140 will be described.

[0142] The housing 140 houses the bobbin 110 and supports the first magnet 130, the first position sensor 170, and the circuit board 190.

[0143] Figure 4a yes Figure 1 The diagram shows a perspective view of the housing 140, circuit board 190, first position sensor 170, and capacitor 195. Figure 4b This is a perspective view of the assembled housing 140, first magnet 130, circuit board 190, first position sensor 170, and capacitor 195.

[0144] Reference Figure 4a and Figure 4bThe housing 140 can be formed as a hollow column. In one example, the housing 140 can be formed with polygonal (e.g., rectangular or octagonal) or circular openings, and the openings in the housing 140 can be formed as through holes penetrating the housing 140 in the optical axis direction.

[0145] The housing 140 may include a plurality of sides 141-1 to 141-4 and corners 142-1 to 142-4.

[0146] In one example, housing 140 may include first to fourth side portions 141-1 to 141-4 spaced apart from each other and first to fourth corner portions 142-1 to 142-4 spaced apart from each other.

[0147] In one example, the first side 141-1 and the second side 141-2 of the housing 140 may face each other or be located in opposite positions, and the third side 141-3 and the fourth side 141-4 of the housing 140 may face each other or be located in opposite positions.

[0148] Each of the corner portions 142-1 to 142-4 of the housing 140 may be disposed or located between two adjacent side portions 141-1 and 141-2, 141-2 and 141-3, 141-3 and 141-4, 141-4 and 141-1, such that the side portions 141-1 to 141-4 are connected to each other.

[0149] In one example, corners 142-1 to 142-4 may be located at the corners of housing 140. In one example, housing 140 has four sides and four corners, but the invention is not limited thereto. The number of sides or corners may be five or more.

[0150] Each of the sides 141-1 to 141-4 of the housing 140 can be configured to be parallel to the corresponding side plate in the side plate 302 of the cover member 300.

[0151] In one example, the sides 141-1 to 141-4 of the housing 140 may correspond to or face the first side 110b-1 of the spool 110, and the corners 142-1 to 142-4 of the housing 140 may correspond to or face the second side 110b-2 of the spool 110.

[0152] The first magnet 130 may be disposed or mounted on the corners 142-1 to 142-4 of the housing 140.

[0153] In one example, the housing 140 may have a placement portion 141a or a storage portion formed in its corners or corner portions 142-1 to 142-4 to house the magnet 130 therein.

[0154] The mounting portion 141a in the housing 140 may be provided in the lower part or lower end of at least one of the corner portions 142-1 to 142-4 of the housing 140.

[0155] In one example, the mounting portion 141a in the housing 140 may be formed in the lower part or the inner side of the lower end of each of the four corner portions 142-1 to 142-4.

[0156] The placement portion 141a in the housing 140 may be formed as a groove corresponding to the first magnet 130, for example, a recessed groove shape, but the present invention is not limited thereto.

[0157] In one example, a first opening may be formed in the side surface of the mounting portion 141a in the housing 140 facing the first coil 120, and a second opening may be formed in the lower surface of the mounting portion 141a in the housing 140 facing the second coil 230, so as to facilitate the mounting of the first magnet 130.

[0158] In one example, the first surface 11a of the first magnet 130 fixed to or disposed in the mounting portion 141a in the housing 140 may be exposed through a first opening in the mounting portion 141a. Furthermore, the lower surface of the first magnet 130 fixed to or disposed in the mounting portion 141a in the housing 140 may be exposed through a second opening in the mounting portion 141a.

[0159] The housing 140 may have escape grooves 41 formed in the upper surfaces of the corners 142-1 to 142-4 to avoid spatial interference with the first frame connection 153 of the upper elastic member 150.

[0160] In one example, the escape groove 41 in the housing 140 may be recessed from the upper surface of the housing 140 and may be closer to the center of the housing 140 than the stop 145 or the adhesive injection holes 146a and 146b. In another example, the escape groove 41 may be located more inwardly than the stop 145 of the housing 140 in the direction toward the center of the housing 140, and the adhesive injection holes 146a and 146b may be located more outwardly than the escape groove 41.

[0161] The housing 140 may have recesses 25a formed in corners 142-1 to 142-4 to correspond to or face the protrusions 115 of the spool 110. The recesses 25a in the housing 140 may be located above the mounting portion 141a in the housing 140. In one example, the recesses 25a in the housing 140 may be formed in the bottom surface of the escape groove 41. In one example, the bottom surface of the recesses 25a may be located lower than the bottom surface of the escape groove 41, and the mounting groove 141a may be located lower than the bottom surface of the escape groove 41.

[0162] The first magnet 130 can be fixed to the mounting portion 141a with an adhesive, but the present invention is not limited thereto.

[0163] In one example, the housing 140 may have one or more adhesive injection holes 146a and 146b formed in the corners 142-1 to 142-4 to receive the injected adhesive. One or more adhesive injection holes 146a and 146b may be recessed from the upper surface of the corners 142-1 to 142-4.

[0164] One or more adhesive injection holes 146a and 146b may be through holes formed through corners 142-1 to 142-4. The adhesive injection holes 146a and 146b may be connected to or communicate with a mounting groove 141a in the housing 140 and may expose at least a portion of the first magnet 130 (e.g., at least a portion of the upper surface of the magnet 130). Because the adhesive injection holes 146a and 146b expose at least a portion of the first magnet 130 (e.g., at least a portion of the upper surface of the magnet 130), adhesive can be effectively applied to the first magnet 130, and thus the bonding force between the first magnet 130 and the housing 140 can be increased.

[0165] The housing 140 may include at least one stop 147a protruding from the outer surface of the sides 141-1 to 141-4. When the housing 140 moves in a direction perpendicular to the optical axis, at least one stop 147a can prevent the housing 140 from colliding with the side plate 302 of the cover member 300.

[0166] To prevent the lower surface of housing 140 from colliding with base 210 and / or circuit board 250, housing 140 may also include a stop (not shown) protruding from its lower surface.

[0167] The housing 140 may have a mounting groove 14a (or placement groove) for housing the circuit board 190, a mounting groove 14b (or placement groove) for housing the first position sensor 170, and a mounting groove 14c (or placement groove) for housing the capacitor 195.

[0168] The mounting groove 14a in the housing 140 may be formed in the upper part or upper end of one of the side portions 141-1 to 141-4 of the housing 140 (e.g., 141-1).

[0169] To facilitate the mounting of the circuit board 190, the mounting groove 14a in the housing 140 may be formed with an opening on its upper surface and having a side surface, a bottom surface, and an opening into the inside of the housing 140. The mounting groove 14a in the housing 140 may have a shape that corresponds to or is consistent with the shape of the circuit board 190.

[0170] The mounting groove 14b in the housing 140 can be formed in the inner surface of the first side portion 141-1 of the housing 140 and can be connected to the mounting groove 14a.

[0171] The mounting groove 14c in the housing 140 can be disposed on one side of the mounting groove 14b, and a protrusion or projection can be disposed between the mounting groove 14b and the mounting groove 14c to separate or isolate the capacitor 195 from the first position sensor 170. This is to arrange the capacitor 195 and the position sensor 170 close to each other, thereby reducing the length of the path used for the electrical connection between the capacitor 195 and the position sensor 170, and thus reducing the amount of noise caused by the long path.

[0172] Capacitor 195 can be set or mounted on the first surface 19b of circuit board 190.

[0173] The capacitor 195 can be a chip type, in which case the chip may include a first terminal corresponding to one end of the capacitor 195 and a second terminal corresponding to the other end of the capacitor 195. The capacitor 195 may be referred to as a "capacitive element" or "capacitor".

[0174] In another embodiment, the capacitor may be implemented as being included in the circuit board 190. In one example, the circuit board 190 may include a capacitor comprising a first conductive layer, a second conductive layer, and an insulating layer (e.g., a dielectric layer) disposed between the first conductive layer and the second conductive layer.

[0175] Capacitor 195 can be connected in parallel to two terminals (e.g., B1 and B2) of circuit board 190 that provides power (or drive signal) to position sensor 170 from the outside.

[0176] Alternatively, capacitor 195 can be connected in parallel to the terminals of the first position sensor 170, which are electrically connected to the first terminal B1 and the second terminal B2 of the circuit board 190.

[0177] In one example, one end of capacitor 195 (or the first terminal of capacitor chip) can be electrically connected to the first terminal B1 of circuit board 190, while the other end of capacitor 195 (or the terminal of capacitor chip) can be electrically connected to the second terminal B2 of circuit board 190.

[0178] Since capacitor 195 is electrically connected in parallel to the first terminal B1 and the second terminal B2 of circuit board 190, capacitor 195 can be used as a smoothing circuit to remove ripple components in the power signals GND and VDD provided from the outside to the first position sensor 170, thereby providing the first position sensor 170 with a stable and consistent power signal.

[0179] Because capacitor 195 is electrically connected in parallel to the first terminal B1 and the second terminal B2 of circuit board 190, the first position sensor 170 can be protected from high-frequency noise, ESD, etc. introduced from the outside.

[0180] In addition, capacitor 195 can prevent overcurrent caused by high-frequency noise, ESD, etc. introduced from the outside from being applied to the first position sensor 170, and can prevent the calibration value of the displacement of the spool 110 obtained based on the signal output from the first position sensor 170 from being reset due to overcurrent.

[0181] Furthermore, to facilitate the installation of the first position sensor 170, the mounting groove 14b in the housing 140 may have an opening at its upper part. The mounting groove 14b may have an opening formed on the inner surface of the first side portion 141-1 of the housing 140 to increase the sensitivity of the first position sensor 170. The mounting groove 14b in the housing 140 may have a shape corresponding to or consistent with the shape of the first position sensor 170.

[0182] In one example, the circuit board 190 can be secured in a mounting groove 14a within the housing 140 using an adhesive member. The adhesive member can be, for example, epoxy resin or double-sided adhesive tape, but the invention is not limited thereto.

[0183] The corners 142-1 to 142-4 of the housing 140 may be provided with support members 220-1 to 220-4.

[0184] The corners 142-1 to 142-4 of the housing 140 may be provided with holes 147 that define a path through which the support members 220-1 to 220-4 extend. In one example, the housing 140 may include holes 147 formed through the upper portion of the corners 142-1 to 142-4 of the housing 140. The number of holes 147 in the housing 140 may be equal to the number of support members.

[0185] In another embodiment, the housing may have an escape structure to avoid spatial interference with the support members 220-1 to 220-4. In one example, the housing of another embodiment may have an escape structure in which holes 147 are recessed from the outer surface of the corners or at least a portion of each of the holes 147 is open.

[0186] One end of each of the support members 220 may be connected or engaged to the upper elastic member 150 through the hole 147. In one example, one end of each of the support members 220 may be connected to the first outer frame of the upper elastic member 150 through the hole 147.

[0187] In one example, the diameter of the hole 147 may gradually increase in the direction from the upper surface to the lower surface of the housing 140 to facilitate the application of a damper, but the invention is not limited thereto. In another embodiment, the diameter of the hole 147 may be constant.

[0188] In order not only to limit the path through which the support members 220-1 to 220-4 extend, but also to avoid spatial interference between the support members 220-1 to 220-4 and the corners 142-1 to 142-4 of the housing 140, escape grooves 148a may be formed in the outer surfaces 148 of the corners 142-1 to 142-4. Each of the escape grooves 148a may connect to a hole 147 in the housing 140 and may have a semi-circular or semi-elliptical shape, but the invention is not limited thereto. The lower part or lower end of each of the escape grooves 148a may connect to the lower surface of the housing 140.

[0189] In one example, the diameter of the escape groove 148a may gradually decrease downwards, but the invention is not limited thereto.

[0190] In addition, in order to prevent the housing 140 from directly colliding with the inner surface of the upper plate 301 of the cover member 300, the housing 140 may be provided with a stop member 145 at its upper part, upper end or upper surface.

[0191] In one example, the stop 145 may be provided on the upper surface of each of the corners 142-1 to 142-4 of the housing 140, but the invention is not limited thereto. In another embodiment, the stop 145 may be provided on each of the sides of the housing 140.

[0192] In addition, to prevent the lower surface of the housing 140 from colliding with the base 210 and / or the circuit board 250, the housing 140 may also be provided with a stop (not shown) at its lower part, lower end or lower surface.

[0193] In addition, the guide protrusion 146 may be formed on the corner of the upper surface of the corners 142-1 to 142-4 of the housing 140 to prevent damper overflow.

[0194] In one example, each of the holes 147 in the housing 140 may be located between the corner of the upper surface of the corresponding corner of the corner 142-1 to 142-4 of the housing 140 (e.g., guide protrusion 146) and the stop 145.

[0195] The housing 140 may have at least one first connecting portion 143 provided at its upper part, upper end or upper surface, which is connected to the first outer frame 152 of the upper elastic member 150.

[0196] The first connecting portion 143 of the housing 140 may be provided on at least one of the side portions 141-1 to 141-4 or on at least one of the corner portions 142-1 to 142-4 of the housing 140.

[0197] The housing 140 may have a second connecting portion 149 at its lower part, lower end or lower surface that is connected to or fixed to the second outer frame 162 of the lower elastic member 160.

[0198] In one example, each of the first connecting portion 143 and the second connecting portion 149 of the housing 140 may be in the form of a protrusion, but the invention is not limited thereto. In another embodiment, each of the first connecting portion and the second connecting portion may be formed as a groove or a plane.

[0199] In one example, using an adhesive member or heat fusion, the first connecting portion 143 of the housing 140 can be connected to the hole 152a in the first outer frame 152 of the upper elastic member 150, and using an adhesive member or heat fusion, the second connecting portion 149 of the housing 140 can be connected to the hole 162a in the second outer frame 162 of the lower elastic member 160.

[0200] In order to avoid spatial interference with the portion of the second outer frame 162-1 to 162-3 of the lower elastic member 160 that intersects with the second frame connection portion 163, the escape groove 44a may be formed in the lower surface of at least one of the side portions 141-1 of the housing 140.

[0201] Next, the first magnet 130 will be described.

[0202] The first magnet 130 may be disposed on at least one of the corners (or corners 142-1 to 142-4) of the housing 140. In one example, the first magnet 130 may be disposed on each of the corners of the housing 140.

[0203] At the initial position of the AF operation unit, the first magnet 130 may be disposed in the housing 140 such that at least a portion thereof overlaps with the first coil 120 in a direction parallel to a line extending through and perpendicular to the optical axis OA.

[0204] In one example, the first magnet 130 may be inserted into or disposed in the placement portion 141a in the corresponding corner of the corners 141-1 to 141-4 of the housing 140.

[0205] In another embodiment, the first magnet 130 may be disposed on the outer surface of each of the corners 141-1 to 141-4 of the housing 140.

[0206] The first magnet 130 may have a polyhedral shape that is easy to place on each of the corners of the housing 140.

[0207] In one example, the area of ​​the first surface 11a of the first magnet 130 may be larger than the area of ​​its second surface 11b. The first surface 11a of the first magnet 130 may be a surface facing the first coil 120 (or the outer surface of the spool 110), and the second surface 11b of the first magnet 130 may be a surface opposite to the first surface 11a.

[0208] In one example, the length of the second surface 11b of the first magnet 130 in the lateral direction may be shorter than the length of its first surface 11a in the lateral direction.

[0209] In one example, the lateral direction of the first surface 11a of the first magnet 130 can be a direction perpendicular to the direction from the lower surface of the first magnet 130 to its upper surface, or it can be a direction perpendicular to the optical axis direction.

[0210] In one example, the lateral direction of the second surface 11b of the first magnet 130 can be a direction perpendicular to the direction from the lower surface of the first magnet 130 to its upper surface, or it can be a direction perpendicular to the optical axis direction.

[0211] In one example, the first magnet 130 may include a portion of its length in the lateral direction that gradually decreases from the center of the housing 140 toward the corners 142-1, 142-2, 142-3 or 142-4 of the housing 140.

[0212] In one example, the first magnet 130 may include a portion whose length in the lateral direction decreases in the direction from the first surface 11a to the second surface 11b. In one example, the lateral direction of the first magnet 130 may be a direction parallel to the first surface 11a of the first magnet 130.

[0213] The first magnet 130 may include a plurality of magnets 130-1 to 130-4 disposed in the housing 140.

[0214] Each of the plurality of magnets 130-1 to 130-4 can be integrally formed and can be configured such that a first surface 11a facing the coil 120 is the S pole and a second surface 11b is the N pole. However, the invention is not limited thereto. In another embodiment, each of the plurality of magnets 130-1 to 130-4 can be configured such that the first surface 11a is the N pole and the second surface 11b is the S pole.

[0215] The first magnet can be positioned or mounted on the corner of the housing 140 such that at least two of them face each other.

[0216] In one example, two pairs of magnets 130-1 and 130-3, and 130-2 and 130-4, configured such that each pair of magnets faces each other, can be disposed on the corners 142-1 to 142-4 of the housing 140. In this case, the planar shape of each of the plurality of magnets 130-1 to 130-4 in the horizontal direction can be polygonal, such as a triangle, pentagon, hexagon, or rhombus.

[0217] In another embodiment, a pair of magnets facing each other may be disposed only at the two opposite corners of the housing 140.

[0218] In another embodiment, the magnet may not be located at the corner of the housing 140, but rather on the side of the housing 140. The circuit board 190, the first position sensor 170, and the capacitor 195 may be located at one of the corners of the housing 140. The sensing magnet may be located on the outer surface of the tubing 110 corresponding to the first position sensor 170. In yet another embodiment, a plurality of magnets may be located on the side of the housing 140, and each magnet may be a polyhedral shape suitable for being located on the side of the housing, such as a cube or cuboid, but the invention is not limited thereto.

[0219] Figure 5 yes Figure 2 The image shows a cross-sectional view of the lens moving device 100 taken along the AB direction. Figure 6 yes Figure 2 The shown lens moving device 100 is a cross-sectional view taken along the CD direction.

[0220] Reference Figure 5 and Figure 6 Each of the second magnet 180 and the third magnet 185 may not overlap with the first coil 120 in a direction perpendicular to the optical axis OA or in a direction parallel to a line perpendicular to and extending through the optical axis, but the invention is not limited thereto. In another embodiment, each of the second magnet 180 and the third magnet 185 may overlap with the first coil 120.

[0221] Furthermore, at the initial position of the AF operation unit, the second magnet 180 may overlap or align with the third magnet 185 in a direction perpendicular to the optical axis OA or in a direction parallel to a line perpendicular to the optical axis and extending through the optical axis, but the invention is not limited thereto. In another embodiment, the second magnet 180 and the third magnet 185 may not overlap each other.

[0222] Furthermore, at the initial position of the AF operation unit, the first position sensor 170 may overlap with the second magnet 180 and the third magnet 185 in a direction perpendicular to the optical axis OA or in a direction parallel to a line perpendicular to the optical axis and extending through the optical axis, but the invention is not limited thereto. In another embodiment, the first position sensor 170 may not overlap with at least one of the second magnet 180 and the third magnet 185.

[0223] Furthermore, the first position sensor 170 may not overlap with the first magnet 130 in a direction perpendicular to the optical axis OA or in a direction parallel to a line that is perpendicular to the optical axis and extends through the optical axis.

[0224] In one example, the first position sensor 170 may not overlap with the first magnet 130 in the direction from the first position sensor 170 toward the first coil 120 or in the direction perpendicular to the optical axis and oriented from the first side 141-1 of the housing 140 toward the center of the housing 140.

[0225] Next, the circuit board 190 and the first position sensor 170 will be described.

[0226] The circuit board 190 may be mounted on or connected to the housing 140.

[0227] In one example, circuit board 190 may be disposed on or connected to a side 141-1 of housing 140. First position sensor 170 may be disposed on or mounted on circuit board 190. In one example, circuit board 190 may be disposed in mounting slot 14a in housing 140.

[0228] In one example, circuit board 190 may be disposed between the first corner 142-1 and the second corner 142-2 of housing 140, and the first terminal B1 to the fourth terminal B4 of circuit board 190 may be electrically connected to the first position sensor 170.

[0229] In one example, the circuit board 190 may not overlap with the corner (e.g., the first corner 142-1) (or bend) of the connecting housing 140 and the imaginary line of the optical axis OA. This is to prevent spatial interference between the support member 220 and the circuit board 190.

[0230] Figure 7a This is an enlarged view of circuit board 190 and the first position sensor 170. Figure 7b It is shown Figure 7a A diagram showing the structure of an embodiment of the first position sensor 170.

[0231] Reference Figure 7a and Figure 7b The circuit board 190 may include terminals B1 to B6 that are electrically connected to external terminals or external devices.

[0232] The first position sensor 170 can be disposed on the first surface 19b of the circuit board 190, and terminals B1 to B6 can be disposed on the second surface 19a of the circuit board 190. However, the present invention is not limited thereto.

[0233] In another embodiment, the first position sensor 170 and terminals B1 to B6 may be disposed on one of the first and second surfaces of the circuit board 180. In yet another embodiment, the first position sensor 170 may be disposed on one of the first and second surfaces of the circuit board 180, and terminals B1 to B6 may be disposed on the other of the first and second surfaces of the circuit board 180.

[0234] Here, the second surface 19a of the circuit board 190 can be the surface of the circuit board 190 opposite to the first surface 19b. In one example, the second surface 19a of the circuit board 190 can be the surface of the circuit board 190 facing the spool 110.

[0235] The circuit board 190 may include a main body S1 and an extension S2 located below the main body S1. The main body S1 may be referred to as the "upper end" and the extension S2 may be referred to as the "lower end".

[0236] The extension S2 can extend downward from the main body S1.

[0237] The main body S1 may have a form that protrudes from the side surfaces 16a and 16b of the extension S2. In one example, the side surfaces 16a and 16b of the extension S2 may be surfaces that connect the first surface 19b of the extension S2 and the second surface 19a of the extension S2.

[0238] The main body S1 may include a first extension region A1 extending toward a first corner 142-1 of the housing 140 and a second extension region A2 extending toward a second corner 142-2 of the housing 140.

[0239] In one example, the first extension region A1 may extend or protrude from the first side surface 16a of the extension S2, and the second extension region A2 may extend or protrude from the second side surface 16b of the extension S2.

[0240] In one example, Figure 7a In the diagram, the length of the first extension region A1 in the lateral direction is shown to be longer than the length of the second extension region A2 in the lateral direction, but the invention is not limited thereto. In another embodiment, the length of the first extension region A1 in the lateral direction may be equal to or shorter than the length of the second extension region A2 in the lateral direction.

[0241] In one example, the length of the main body S1 of the circuit board 190 in the lateral direction may be longer than the length of the extension S2 in the lateral direction.

[0242] In one example, the first terminals B1 to the fourth terminals B4 of the circuit board 190 can be disposed on the second surface 19a of the main body S1, thereby being spaced apart from each other. In another example, the four terminals B1 to B4 can be arranged in a row in the lateral direction of the circuit board 190.

[0243] The first terminal B1 and the second terminal B2 can be disposed adjacent to each end of the main body S1 of the circuit board 190. That is, each of the first terminal B1 and the second terminal B2 can be disposed adjacent to one of the corresponding ends of the main body S1 of the circuit board 190.

[0244] In one example, the first terminal B1 of the circuit board 190 may be located at one end of the circuit board 190 (e.g., the upper end), the second terminal B1 may be located at the other end of the circuit board 190, the third terminal B3 may be located between the first terminal B1 and the second terminal B2, and the fourth terminal B4 may be located between the third terminal B3 and the first terminal B1.

[0245] The first terminal B1 of the circuit board 190 can be disposed in the first extension area A1 of the main body S1 of the circuit board 190, and the second terminal B2 can be disposed in the second extension area A2 of the extension S1 of the circuit board 190.

[0246] The first terminal B1 to the fourth terminal B4 can be positioned closer to the upper surface 19c than the lower surface of the circuit board 190.

[0247] In one example, the first terminal B1 to the fourth terminal B4 can be formed to be continuous with the second surface 19a of the main body S1 of the circuit board 190 and the upper surface 19c that is continuous with the second surface 19a.

[0248] Furthermore, in one example, at least one of the first terminal B1 to the fourth terminal B4 may include a groove 7a or a via formed in the upper surface 19c of the circuit board 190.

[0249] In one example, each of the third terminal B3 and the fourth terminal B4 may include a curved portion recessed from the upper surface 19c of the circuit board 190, such as a semi-circular conductive portion or a groove 7a.

[0250] The groove 7a is used to increase the contact area between the solder and terminals B3 and B4, thereby increasing adhesion and improving soldering efficiency.

[0251] The fifth terminal B5 and the sixth terminal B6 of the circuit board 190 can be disposed on the second surface 19a of the extension S2 of the circuit board 190, thereby being spaced apart from each other.

[0252] The circuit board 190 may have a recess 8a or a hole formed between the fifth terminal B5 and the sixth terminal B6. The recess 8a may be recessed from the lower surface of the circuit board 190 and may open to both the first surface 19b and the second surface 19a of the circuit board 190.

[0253] The spacing between the fifth terminal B5 and the sixth terminal B6 can be shorter than the spacing between two adjacent terminals from the first terminal B1 to the fourth terminal B4. When performing soldering for electrical connection with external equipment, the groove 8a prevents solder from being applied to the portion between the fifth terminal B5 and the sixth terminal B6, thereby preventing an electrical short circuit between the fifth terminal B5 and the sixth terminal B6.

[0254] Furthermore, in one example, at least one of the fifth terminal B5 and the sixth terminal B6 may include a groove 7b or a conductive portion formed in the lower surface of the circuit board 190.

[0255] In one example, each of the fifth terminal B5 and the sixth terminal B6 may include a curved portion recessed from the lower surface of the circuit board 190, such as a semi-circular conduction portion or a groove.

[0256] The groove 7b is used to increase the contact area between the solder and the fifth terminal B5 and the sixth terminal B6, thereby increasing adhesion and improving welding efficiency.

[0257] The circuit board 190 may include a groove 90a formed between the second terminal B2 and the third terminal B3, and a groove 90b formed between the first terminal B1 and the fourth terminal B4. Here, grooves 90a and 90b may be referred to as "escape grooves".

[0258] Each of the first groove 90a and the second groove 90b can be recessed from the upper surface 19c of the circuit board 190 and can open to the first surface 19b and the second surface 19a of the circuit board 190.

[0259] The first groove 90a in the circuit board 190 can be formed to avoid spatial interference with the first outer frame 151 of the third upper elastic unit 150-3, and the second groove 90b in the circuit board 190 can be formed to avoid spatial interference with the first outer frame 151 of the fourth upper elastic unit 150-4.

[0260] In one example, board 190 can be implemented as a printed circuit board or an FPCB.

[0261] The circuit board 190 may include circuit patterns or wiring (not shown) for electrically connecting the first to sixth terminals B1 to B6 to the first position sensor 170.

[0262] The first position sensor 170 can detect the magnetic field or magnetic field strength of the second magnet 180 installed on the line cylinder 110 during the movement of the line cylinder 110, and can output an output signal corresponding to the detection result.

[0263] The first position sensor 170 can be mounted on a circuit board 190 disposed in the housing 140 and can be fixed to the housing 140. In one example, the first position sensor 170 can be disposed in a mounting slot 14b in the housing 190 and can move with the housing 140 during hand shake correction.

[0264] The first position sensor 170 may be disposed on the first surface 19b of the circuit board 190. In another embodiment, the first position sensor 170 may be disposed on the second surface 19a of the circuit board 190.

[0265] The first position sensor 170 may include a Hall sensor 1061 and a driver 1062.

[0266] In one example, the Hall sensor 1061 may be made of silicon-based material, and the output VH of the Hall sensor 1061 may increase as the ambient temperature rises. In one example, the ambient temperature may be the temperature of the lens moving device, such as the temperature of the circuit board 190, the temperature of the Hall sensor 1061, or the temperature of the driver 1062.

[0267] In another embodiment, the Hall sensor 1061 may be made of GaAs, and the output VH of the Hall sensor 1061 may decrease as the ambient temperature increases. In another embodiment, the output of the Hall sensor 1061 may have a slope of approximately -0.06% / °C relative to the ambient temperature.

[0268] The first position sensor 170 may further include a temperature sensing element 1063 capable of detecting ambient temperature. The temperature sensing element 1063 may output a temperature detection signal Ts corresponding to the ambient temperature detection result of the first position sensor 170 to the driver 1062.

[0269] In one example, the Hall sensor 1061 of the first position sensor 190 can generate an output VH corresponding to the detection result of the magnetic force intensity of the second magnet 180. In one example, the intensity of the output of the first position sensor 190 can be proportional to the intensity of the magnetic force of the second magnet 180.

[0270] The driver 1062 can output a drive signal dV for driving the Hall sensor 1061 and a drive signal Id1 for driving the first coil 120.

[0271] In one example, by using a data communication protocol such as I2C communication, driver 1062 can receive clock signal SCL, data signal SDA, and power signals VDD and GND from controller 830 or 780.

[0272] Here, the second power signal VDD can be a predetermined voltage used to drive the driver 1062. The first power signal GND can be ground voltage or 0V, but the invention is not limited thereto. In another embodiment, the first power signal GND can be a voltage lower than the second power signal. In one example, each of the first and second power signals can be a DC voltage and / or an AC voltage, but the invention is not limited thereto.

[0273] The driver 1062 can use the clock signal SCL and the power signals VDD and GND to generate a drive signal dV for driving the Hall sensor 1061 and a drive signal Id1 for driving the first coil 120.

[0274] The first position sensor 170 may include four terminals for transmitting and receiving clock signal SCL, data signal SDA, and power signals VDD and GND, as well as two terminals for providing drive signals to the first coil 120.

[0275] Additionally, the driver 1062 can receive the output VH of the Hall sensor 1061 and can send the clock signal SCL and data signal SDA corresponding to the output VH of the Hall sensor 1061 to the controller 830 or 780 via data communication using a protocol, such as I2C communication.

[0276] In addition, the driver 1062 can receive the temperature detection signal Ts detected by the temperature sensing element 1063 and send the temperature detection signal Ts to the controller 830 or 780 by using data communication protocols, such as I2C communication.

[0277] The controller 830 or 780 can perform temperature compensation on the output VH from the Hall sensor 1061 based on the change in ambient temperature detected by the temperature sensing element 1063 of the first position sensor 170.

[0278] In one example, when the drive signal dV or bias signal from the Hall sensor 1061 is 1mA, the output VH of the Hall sensor 1061 from the first position sensor 170 can be from -20mV to +20mV, but the present invention is not limited thereto.

[0279] When temperature compensation is performed on the output VH of the Hall sensor 1061, which has a negative slope relative to the change in ambient temperature, the output VH of the Hall sensor 1061 of the first position sensor 170 can be from 0mV to +30mV, but the present invention is not limited thereto.

[0280] When the output of the Hall sensor 1061 from the first position sensor 170 is plotted in the xy coordinate system, the range of the output of the Hall sensor 1061 from the first position sensor 170 appears in the first quadrant (e.g., 0mV to +30mV) for the following reasons.

[0281] Because the outputs of Hall sensor 1061 in the first quadrant of the xy coordinate system and in the third quadrant of the xy coordinate system shift in opposite directions according to changes in ambient temperature, the accuracy and reliability of the Hall sensors may decrease when both the first and third quadrants are used as the AF operating control area. Therefore, to accurately compensate for changes in ambient temperature, a specific range in the first quadrant can be set to the output range of the Hall sensor 1061 from the first position sensor 170.

[0282] The first position sensor 170 may include first to fourth terminals for transmitting and receiving two power signals VDD and GND, a clock signal SCL and a data signal SDA, and fifth and sixth terminals for providing drive signals to the first coil 120.

[0283] Each of the first to fourth terminals of the first position sensor 170 can be electrically connected to a corresponding terminal of the first terminal B1 to the fourth terminal B4 of the circuit board 190, and each of the fifth and sixth terminals of the first position sensor 170 can be electrically connected to a corresponding terminal of the fifth terminal B5 and the sixth terminal B6 of the circuit board 190.

[0284] In another embodiment, the first position sensor 170 may be implemented as a single position detection sensor, such as a Hall sensor. In this case, the first position sensor 170 may include two input terminals for receiving electrical signals and two output terminals for outputting signals, and can provide drive signals to the first coil 120 from the outside via the circuit board 250.

[0285] The first terminals B1 to the fourth terminals B4 of the circuit board 190 can be electrically connected to terminals 251-1 to 251-n (n is a natural number greater than 1 (n>1)) via the upper elastic units 150-1 to 150-4 and the support members 220-1 to 220-4, thereby the first position sensor 170 can be electrically connected to terminals 251-1 to 251-n (n=4) of the circuit board 250.

[0286] In one example, each of the upper elastic units 150-1 to 150-4 can be directly connected to a corresponding terminal among the first to fourth terminals of the circuit board 180, thereby being electrically connected to that terminal. Furthermore, one end of each of the support members 220-1 to 220-4 can be directly connected to a corresponding upper elastic unit among the upper elastic units 150-1 to 150-4 via a conductive adhesive member, such as solder, and the other end of each of the support members 220-1 to 220-4 can be directly connected to the circuit board 250.

[0287] Furthermore, the fifth terminal B5 and the sixth terminal B6 of the circuit board 190 can be connected to the lower elastic units 160-1 and 160-2, and the first position sensor 170 can be electrically connected to the first coil 120 via the lower elastic units 160-1 and 160-2.

[0288] In one example, the fifth terminal B5 of the circuit board 190 can be connected to the first lower elastic unit 160-1, and the sixth terminal B6 of the circuit board 190 can be connected to the second lower elastic unit 160-2.

[0289] The lens moving device 100 is configured such that a first position sensor 170 is disposed in the housing 140, and a second magnet 180 is disposed on the spool 110. In another embodiment, the first position sensor may be disposed on the spool, and the second magnet may be disposed in the housing. In this case, a circuit board may be disposed on the spool, and a third magnet may be disposed in the housing.

[0290] Next, the upper elastic member 150, the lower elastic member 160, and the support member 220 will be described.

[0291] Figure 8 It is shown Figure 1 The view of the upper elastic member 150 shown. Figure 9 It is shown Figure 1 The view shown is of the lower elastic member 160. Figure 10 This is a perspective view of the assembled upper elastic member 150, lower elastic member 160, base 210, support member 220, second coil 230, and circuit board 250. Figure 11 This is a view showing the connection between the first to fourth terminals B1 to B4 of the circuit board 190 and the upper elastic units 150-1 to 150-4. Figure 12 This is a view showing the connection between the fifth terminal B5 and the sixth terminal B6 of the circuit board 190 and the lower elastic units 160-1 and 160-2. Figure 13a This is an exploded perspective view of the second coil 230, circuit board 250, base 210, and second position sensor 240. Figure 13b yes Figure 13aA partial enlarged view of the base 210 shown. Figure 14 This is a perspective view of the base 210-1 according to another embodiment. Figure 15 This is a bottom view of the second coil 230 and the circuit board 190. Figure 16 This is a bottom view of the second coil 230, circuit board 250, and solder 39A. Figure 17 yes Figure 1 Bottom view of the lens moving device 100 shown.

[0292] Reference Figures 8 to 17 The upper elastic member 150 can be connected to the upper part, upper end or upper surface of the spool 110, and the lower elastic member 160 can be connected to the lower part, lower end or lower surface of the spool 110.

[0293] In one example, the upper elastic member 150 may be connected to the upper part, upper end or upper surface of the spool 110 and the upper part, upper end or upper surface of the housing 140, and the lower elastic member 160 may be connected to the lower part, lower end or lower surface of the spool 110 and the lower part, lower end or lower surface of the housing 140.

[0294] The upper elastic member 150 and the lower elastic member 160 can elastically support the spool 110 relative to the housing 140.

[0295] The support member 220 can support the housing 140 such that the housing 140 is movable relative to the base 210 in a direction perpendicular to the optical axis, and at least one of the upper elastic member 150 and the lower elastic member 160 can be electrically connected to the circuit board 250.

[0296] Reference Figure 8 The upper elastic member 150 may include a plurality of upper elastic units 150-1 to 150-4 that are electrically insulated from each other. Although Figure 10 Four upper elastic units electrically insulated from each other are shown, but the number of upper elastic units is not limited to four. In another embodiment, the number of upper elastic units may be three or more.

[0297] Each of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 can be directly connected to the corresponding terminal of the first terminal B1 to the fourth terminal B4 of the circuit board 190, thereby electrically connecting to that terminal.

[0298] A portion of each of the plurality of upper elastic units may be disposed on a first side 141-1 of the housing 140 on which the circuit board 190 is disposed, and at least one upper elastic unit may be disposed on each of the remaining second side 141-2 to fourth side 141-4 of the housing 140 other than the first side 141-1.

[0299] Each of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 may include a first outer frame 152 connected to the housing 140.

[0300] In one example, each of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 may be disposed at a corresponding corner of the corner of the housing 140, and may include a first outer frame 152 connected to the corresponding corner of the corner of the housing 140.

[0301] At least one of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 may further include a first inner frame 151 connected to the bobbin 110 and a first frame connecting portion 153 that interconnects the first inner frame 151 and the first outer frame 152.

[0302] exist Figure 8 In the embodiments, each of the first upper elastic unit 150-1 and the second upper elastic unit 150-2 may include only the first outer frame, without including the first inner frame or the first frame connection portion, and a portion of each of the first upper elastic unit 150-1 and the second upper elastic unit 150-2 may be spaced apart from the bobbin 110.

[0303] Each of the third upper elastic unit 150-3 and the fourth upper elastic unit 150-4 may include a first inner frame 151, a first outer frame and a first frame connecting portion 153, but the present invention is not limited thereto.

[0304] In one example, the first inner frame 151 of each of the third upper elastic unit 150-3 and the fourth upper elastic unit 150-4 may be formed with a hole 151a for connecting with the first connecting portion 113 of the bobbin 110, but the invention is not limited thereto. In one example, the hole 152a in the first inner frame 151 may be formed with at least one slit 51a for the entry of an adhesive member between the first connecting portion 113 of the bobbin 110 and the hole 151a.

[0305] The first outer frame 152 of each of the first upper elastic member 150-1 to the fourth upper elastic member 150-4 may be formed with a hole 152a for connection with the first connecting portion 143 of the housing 140.

[0306] The first outer frame 151 of each of the first upper elastic units 150-1 to the fourth upper elastic units 150-4 may include a main body portion connected to the housing 140 and connecting terminals P1 to P4 connected to corresponding terminals of the first terminals B1 to the fourth terminals B4 of the circuit board 190. Here, connecting terminals P1 to P4 may be referred to as "extensions". In one example, a support member 220 may be connected to the main body portion of the first outer frame 151.

[0307] The first outer frame 151 of each of the first upper elastic units 150-1 to the fourth upper elastic units 150-4 may include a first connecting portion 520 connected to the housing 140, a second connecting portion 510 connected to the corresponding support members of the support members 220-1 to 220-4, a connecting portion 530 interconnecting the first connecting portion 520 and the second connecting portion 510, and extension portions P1 to P4 connected to the first connecting portion 520 and extending to the first side portion 141-1 of the housing 140.

[0308] In one example, the main body of each of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 may be the first connecting portion 520, or may include the first connecting portion 520. Furthermore, in one example, the main body of each of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 may also include at least one of the second connecting portion 510 and the connecting portion 530.

[0309] In one example, using solder or conductive adhesive, one end of the first support member 220-1 can be connected to the second connection portion 510 of the first upper elastic unit 150-1, one end of the second support member 220-2 can be connected to the second connection portion 510 of the second upper elastic unit 150-1, one end of the third support member 220-3 can be connected to the second connection portion 510 of the third upper elastic unit 150-3, and one end of the fourth support member 220-4 can be connected to the second connection portion 510 of the fourth upper elastic unit 150-4.

[0310] The second connecting portion 510 may have a hole 52 to allow the corresponding support member of support members 220-1 to 220-4 to pass through the hole 52. One end of the corresponding support member of support members 220-1 to 220-4 passing through the hole 52 can be connected by a conductive adhesive member or solder 901 (see reference). Figure 10 It is directly connected to the second connecting part 510, and the second connecting part 510 and the corresponding support members in the support members 220-1 to 220-4 can be electrically connected to each other.

[0311] In one example, the second connection 510 may include a hole 52 and a region surrounding the hole 52, wherein solder 901 is provided for connection to the corresponding support members in support members 220-1 to 220-4.

[0312] The first connecting portion 520 may include at least one connecting region (e.g., 5a or 5b) that is connected to the housing 140 (e.g., corner portions 142-1 to 142-4).

[0313] In one example, the connection area (e.g., 5a or 5b) of the first connection portion 520 may be formed with at least one hole 152a for connection to the first connection portion 143 of the housing 140.

[0314] In one example, each of the connecting regions 5a and 5b may be formed with one or more holes, and each of the corner portions 142-1 to 142-4 of the housing 140 may be provided with one or more first connecting portions corresponding to the holes.

[0315] In one example, in order to support the housing 140 in a balanced state, the connection regions 5a and 5b of the first connection portions 520 of the first upper elastic unit 150-1 to the fourth upper elastic unit 150-4 may be formed symmetrically based on reference lines (e.g., 501 and 502), but the invention is not limited thereto.

[0316] Furthermore, the first connecting portions 143 of the housing 140 can be symmetrically arranged based on reference lines (e.g., 501 and 502). Two first connecting portions 143 can be arranged on each side of each reference line, but the invention is not limited thereto.

[0317] Each of reference lines 501 and 502 may be a line extending between the center point 101 and one of the corners 142-1 to 142-4 of the housing 140. In one example, each of reference lines 501 and 502 may be a line extending through the center point 101 and two corners 142-1 to 142-4 of the housing 140 that face each other in the diagonal direction of the housing 140.

[0318] Here, center point 101 can be the center of housing 140, the center of bobbin 110, or the center of upper elastic member 150. Center point 101 can be the spatial center of the aforementioned components 140, 110, or 150.

[0319] Furthermore, in one example, the corner of each of the corners of the housing 140 may be aligned with the center of the corresponding corner of the housing 140 or a corresponding corner.

[0320] exist Figure 8 In one embodiment, each of the connection regions 5a and 5b of the first connection portion 520 of the first outer frame 152 is configured to have a hole 152a, but the invention is not limited thereto. In another embodiment, each of the connection regions may be formed in any of a variety of shapes suitable for connection with the housing 140, such as a groove shape.

[0321] In one example, the hole 152a in the first connection portion 520 may form at least one slit 52a for the adhesive member to enter between the first connection portion 143 of the housing 140 and the hole 152a.

[0322] The connecting part 530 can interconnect the second connecting part 510 and the first connecting part 520.

[0323] In one example, the connecting part 530 can interconnect the connecting parts 5a and 5b of the second connecting part 510 with the connecting parts 520 of the first connecting part 520.

[0324] In one example, the connecting portion 530 may include a first connecting portion 530a that interconnects a first connecting region 5a of a first connecting portion 520 of each of the first upper elastic units 150-1 to the fourth upper elastic units 150-4 with a second connecting portion 510, and a second connecting portion 530b that interconnects a second connecting region 5b of a first connecting portion 520 with a second connecting portion 510.

[0325] In one example, the first outer frame 151 may include a connection area 5c that directly interconnects the first connection area 5a and the second connection area 5b, but the invention is not limited thereto.

[0326] Each of the first connecting portion 530a and the second connecting portion 530b may include a bent portion or a curved portion that is bent at least once, but the invention is not limited thereto. In another embodiment, each of the first connecting portion and the second connecting portion may be linear.

[0327] The width of the connecting portion 530 may be smaller than the width of the first connecting portion 520. Furthermore, the width of the connecting portion 530 may be smaller than the width (or diameter) of the first connecting portion. In another embodiment, the width of the connecting portion 530 may be equal to the width of the first connecting portion 520, and may also be equal to the width (or diameter) of the first connecting portion.

[0328] In one example, the first connecting portion 520 may contact the upper surface of the corner portions 142-1 to 142-4 of the housing 140 and may be supported by the corner portions 142-1 to 142-4 of the housing 140. In another example, the connecting portion 530 may not be supported by the upper surface of the housing 140 and may be spaced apart from the housing 140. Additionally, to prevent oscillations caused by vibration, a damper may be filled in the space between the connecting portion 530 and the housing 140 (see...). Figure 11 (DA3).

[0329] The width of each of the first connecting portion 530a and the second connecting portion 530b can be smaller than the width of the first connecting portion 520, so that the connecting portion 530 can be easily moved along the first direction. Therefore, the stress applied to the upper elastic units 150-1 to 150-4 and the stress applied to the support members 220-1 to 220-4 can be dispersed.

[0330] Each of the first extension P1 and the second extension P2 of the first outer frame of the first upper elastic unit 150-1 and the second upper elastic unit 150-2 can extend from the first connecting portion 520 (e.g., the first connecting area 5a) to the corresponding terminal of the first terminal B1 and the second terminal B2 of the circuit board 190 located at the first side portion 141-1 of the housing 140.

[0331] The first connecting portion 520 of the third upper elastic unit 150-3 may further include at least one connecting region 6a or 6b connected to at least one of the fourth side portion 141-4 and the second corner portion 142-2 of the housing 140.

[0332] Furthermore, the first connecting portion 520 of the fourth upper elastic unit 150-4 may also include at least one connecting region 6c or 6d connected to at least one of the third side portion 141-3 and the first corner portion 142-1 of the housing 140.

[0334] One end of each of the first extension P1 to the fourth extension P4 can be connected to the corresponding terminal of the first terminal B1 to the fourth terminal B4 of the circuit board 190 by solder or conductive adhesive.

[0335] Each of the first extension P1 and the second extension P2 may be linear, but the invention is not limited thereto. In another embodiment, each of the first extension and the second extension may include a bend or a curve.

[0336] To facilitate connection with the corresponding terminals in the third terminal B3 and the fourth terminal B4 of the circuit board 190, each of the third extension P3 and the fourth extension P4 may include a bend or a flexure.

[0337] The first outer frame of the third upper elastic unit 150-3 may also include a first extension frame 154-1, which is connected to both the first connecting part 520 and the extension part P3, and is located on the fourth side part 141-4 and the second corner part 142-2 of the housing 140.

[0338] In order to increase the connection force between the first extension frame 154 and the housing 140 and thus prevent the third upper elastic unit 150-3 from tilting up, the first extension frame 154-1 may include at least one connection area 6a or 6b connected to the housing 140, each of the connection areas 6a and 6b may be formed with a hole for connecting to the first connection portion 143 of the housing 140.

[0339] The first outer frame of the fourth upper elastic unit 150-4 may also include a second extension frame 154-2, which is connected to both the first connecting part 520 and the extension part P4, and is located on the third side part 141-3 and the first corner part 142-1 of the housing 140.

[0340] In order to increase the connection force between the second extension frame 154-2 and the housing 140 and thus prevent the fourth upper elastic unit 150-4 from tilting up, the second extension frame 154-2 may include at least one connection region 6c or 6d connected to the housing 140, each of the connection regions 6c and 6d may be formed with a hole for connecting to the first connection portion 143 of the housing 140.

[0341] Although Figure 8 In the diagram, each of the third upper elastic unit 150-3 and the fourth upper elastic unit 150-4 is shown to include two first frame connecting portions, but the invention is not limited thereto. The number of first frame connecting portions may be one, three or more.

With the aid of extensions P1 to P4, the upper elastic units 150-1 to 150-4 can be easily connected to the first to fourth terminals B1 to B4 provided on the main body portion S1 of the circuit board 190.

[0343] Because the four terminals B1 to B4 provided at the main body S1 of the circuit board 190 provided on the first side 141-1 of the housing 140 are directly electrically connected to the first to fourth upper elastic units 150-1 to 150-4, a portion of the first outer frame 151 of each of the first to fourth upper elastic units 150-1 to 150-4 can be provided on the first side 141-1 of the housing 140.

[0344] Each of the upper elastic units 150-1 to 150-4 may be disposed on or connected to the corresponding corner of the corner 142-1 to 142-4 of the housing 140, and may include extensions P1 to P4 extending to the first side 141-1 of the housing 140.

[0345] Reference Figure 11Each of the extensions P1 to P4 of the upper elastic units 150-1 to 150-4 can be directly connected to the corresponding terminal of the four terminals B1 to B4 provided at the main body S1 of the circuit board 190 via a conductive adhesive member 71, such as solder or conductive epoxy resin.

In one example, the second part 1b of the third extension P3 may extend from the inner surface of the housing 140 to the outer surface of the housing 140.

[0356] A portion of the third extension P3 of the third upper elastic unit 150-3 (e.g., the second part 1b) may be located in the first groove 90a in the circuit board 190, or may extend through the first groove 90a.

[0357] The fourth extension (or "fourth connecting terminal") P4 of the fourth upper elastic unit 150-4 may include at least two bending regions 2c and 2d.

[0368] The width of each of the connecting frames 164-1 to 164-4 may be smaller than the width of each of the second outer frames 162-1 to 162-3, but the invention is not limited thereto.

[0369] To avoid spatial interference with the second coil 230 and the first magnet 130, the connecting frames 164-1 to 164-4 can be located outside the coil units 230-1 to 230-4 and the magnets 130-1 to 130-4. Here, the outside of the coil units 230-1 to 230-4 and the magnets 130-1 to 130-4 can be the opposite side of the area where the coil units 230-1 to 230-4 and the magnets 130-1 to 130-4 are located, relative to the area where the center of the bobbin 110 or the center of the housing 140 is located.

[0370] Furthermore, in one example, the connecting frames 164-1 to 164-4 may be arranged so as not to overlap with the coil units 230-1 to 230-4 and / or the magnets 130-1 to 130-4 in the optical axis direction, but the invention is not limited thereto.

[0375] Support members 220-1 to 220-4 may be spaced apart from the housing 140, rather than being fixed to the housing 140. One end of each of the support members 220-1 to 220-4 may be directly connected or linked to the second connecting portion 510 of the corresponding upper elastic unit in the upper elastic units 150-1 to 150-4, while the other end of each of the support members 220-1 to 220-4 may be directly connected or linked to the circuit board 250.

[0376] In one example, support members 220-1 to 220-4 may pass through holes 147 formed in the corners 142-1 to 142-4 of the housing 140, but the invention is not limited thereto.

The electrical signal GND can be provided to the first position sensor 170 through the second terminal 251-2 of circuit board 250, the second support member 220-2, the second upper elastic unit 150-2, and the second terminal B2 of circuit board 190.

[0388] Furthermore, in one example, the clock signal SCL can be provided to the first position sensor 170 via the third terminal 251-3 of circuit board 250, the third support member 220-3, the third upper elastic unit 150-3, and the third terminal B3 of circuit board 190. The data signal SDA can be provided to the first position sensor 170 via the fourth terminal 251-4 of circuit board 250, the fourth support member 220-4, the fourth upper elastic unit 150-4, and the fourth terminal B4 of circuit board 190.

[0390] The second outer frame 162-1 of the first lower elastic unit 160-1 may include a first joint 81a, wherein the fifth terminal B5 of the circuit board 190 is connected to the first joint 81a by solder or a conductive adhesive member. Furthermore, the second outer frame 162-1 of the second lower elastic unit 160-2 may include a second joint 81b, wherein the sixth terminal B5 of the circuit board 190 is connected to the second joint 81b by solder or a conductive adhesive member.

[0391] In one example, the second outer frame 162-1 of the first lower elastic unit 160-1 may include a first hole (or a first groove) 82a, wherein the fifth terminal B5 of the circuit board 190 is inserted into or disposed in the first hole 82a, and the second outer frame 162-1 of the second lower elastic unit 160-2 may include a second hole (or a second groove) 82b, wherein the sixth terminal B6 of the circuit board 190 is inserted into or disposed in the second hole 82b.

[0392] In one example, a first hole 82a may be formed in the first joint portion 81a of the first lower elastic unit 160-1, and a second hole 82b may be formed in the second joint portion 81b of the second lower elastic unit 160-2.

[0393] In one example, each of the first hole 82a and the second hole 82b may be formed through the second outer frame 161-1 and may have an opening that opens to one side of the second outer frame 161-1, but the invention is not limited thereto. In another embodiment, the opening that opens to one side of the second outer frame 161-1 may not be formed.

Therefore, the connection area can be increased, and thus the connection force between the terminal and the joint can be increased, and the soldering efficiency between the terminal and the joint can be improved.

[0395] Reference Figure 12 One end (e.g., lower end or lower surface) of each of the fifth terminal B5 and the sixth terminal B6 can be located lower than the lower end or lower surface of the second outer frame 162-1 of the first lower elastic unit 160-1 and the second lower elastic unit 160-2. Figure 12 In the bottom view shown, the lower surface of each of the fifth terminal B5 and the sixth terminal B6 is shown positioned lower than the lower end or lower surface of the second outer frame 162-1. This is to improve the welding efficiency between one end of each of the fifth terminal B5 and the first joint 81a and the second joint 81b of the first lower elastic unit 160-1 and the second lower elastic unit 160-2.

[0396] Additionally, refer to Figure 12 The housing 140 may have a recess 31 recessed from the lower surface of the first side portion 141-1. In one example, the bottom surface of the recess 31 in the housing 140 may have a height difference relative to the lower surface of the housing 140 in the optical axis direction. In another example, the bottom surface of the recess 31 in the housing 140 may be located at a higher position than the lower surface of the housing 140.

[0397] The groove 31 in the housing 140 can overlap with the first joint 81a and the second joint 81b of the first lower elastic unit 160-1 and the second lower elastic unit 160-2 in the optical axis direction.

[0398] Furthermore, the groove 31 in the housing 140 may overlap with the holes 82a and 82b in the second outer frame 162-1 of the first lower elastic unit 160-1 and the second lower elastic unit 160-2 in the optical axis direction, but the invention is not limited thereto. In another embodiment, the groove may not overlap with these holes.

[0399] By utilizing the recess 31 in the housing 140, the exposure area of ​​the fifth terminal B5 and the sixth terminal B6 of the circuit board 190 exposed from the housing 140 can be increased, and space can be ensured for setting solder or conductive adhesive components, thereby improving soldering efficiency and reducing the length of solder protruding downward from the lower surface of the second outer frame 162-1. Therefore, spatial interference with the second coil 230, circuit board 250, or base 210 located below the lower elastic unit can be minimized or prevented.

[0400] Furthermore, the lower surface 11c of the first magnet 130 disposed on the mounting portion 141a of the housing 140 can be located at a lower position than the lower surfaces of the second outer frames 162-1 to 162-3 of the first lower elastic unit 162-1 and the second lower elastic unit 162-2. This is to reduce the spacing between the second coil 230 and the first magnet 130, thereby increasing the electromagnetic force used for OIS operation.

[0401] In another embodiment, the lower surface of the first magnet 130 may be located at a position that is higher than or at the same height as the lower surfaces of the second outer frame 162-1 to 162-3 or the lower surface of the housing 140.

[0402] In order to separate the first magnet 130 from the second coil 230 and the circuit board 250, the other end of the support member 220 can be connected to the circuit board 250 (or circuit member 231) at a position lower than the lower surface 11c of the first magnet 130.

[0403] Each of the upper elastic member 150, the lower elastic member 160, and the support member 220 can be implemented as a conductive member that provides elastic support.

[0404] In one example, each of the upper elastic member 150 and the lower elastic member 160 may be implemented as a leaf spring, and the support member 220 may be implemented as a suspension wire, leaf spring, or coil spring. In another embodiment, the support member 220 may be integrally formed with the upper elastic member 150.

[0405] In order to absorb and reduce the vibration of the bobbin 110, the lens moving device 100 may include a damper disposed between the upper elastic member 150 (or the lower elastic member 160) and the bobbin 110 and / or between the upper elastic member 150 (or the lower elastic member 160) and the housing 140.

[0406] In one example, damper DA1 (reference) Figure 11The damper DA2 can be disposed in the space between the frame connection portion 153 or 163 of the upper elastic member 150 (or lower elastic member 160) and the bobbin 110. In another embodiment, the damper DA2 can be disposed in the space between the frame connection portion 153 or 163 of the upper elastic member 150 (or lower elastic member 160) and the housing 140.

[0407] In addition, in one example, the damper DA3 may be disposed between the connection 530 of the outer frame 152 of the upper elastic member 150 and the housing 140.

[0408] Furthermore, in one example, a damper may be disposed at one end of each of the support members 220-1 to 220-4. In one example, damper DA4 may be disposed in a hole 147 in the housing 140.

[0409] Figure 11 Some dampers are shown on the upper elastic member 150-1, the spool 110, the housing 140, and the support member 220-1. Other dampers can be similarly applied to the other upper elastic members 150-2 to 150-4, the spool 110, the housing 140, and the other support members 220-2 to 220-4.

[0410] Alternatively, this embodiment may include Figure 11 At least one of the dampers DA1 to DA5 shown.

[0411] Next, the base 210, the circuit board 250, and the second coil 230 will be described.

[0412] Reference Figure 13a The base 210 may have an opening C3 corresponding to the opening in the spool 110 and / or the opening in the housing 140, and may have a shape consistent with or corresponding to the shape of the cover member 300, such as a rectangle. In one example, the opening C3 in the base 210 may be a through hole formed through the base 210 along the optical axis.

[0413] The base 210 may include a step 211 coated with an adhesive for bonding the cover member 300 to the base 210. In this case, the step 211 may guide the connection of the cover member 300 to the upper side plate 302 of the base, and the lower end of the side plate 302 of the cover member 300 may contact the step 211. The step 211 of the base 210 may be joined and fixed to the lower end of the side plate 302 of the cover member 300 by an adhesive or the like.

[0414] A support portion (or retaining portion) 255 may be disposed in the region of the base 210 facing the terminal members 253 on which the circuit board 250 is disposed. The support portion 255 may support the terminal members 253 of the circuit board 250. In one example, the support portion 255 may be formed as a recessed groove from the outer surface of the base 210, but the invention is not limited thereto. In another embodiment, the support portion may be formed as a flat surface coplanar with the outer surface of the base 210, or it may be formed as a protrusion.

[0415] A protrusion 48 or projection extending or protruding towards the outer surface of the base 210 may be formed on the side surface of the circuit board 250. The protrusion 250 may protrude from the outer surface of the circuit board 250 towards the outer surface of the base 210. A groove 28 or connecting groove having a shape corresponding to the shape of the protrusion 48 of the circuit board 250 may be formed in the outer surface of the base 210 at a position corresponding to the position of the protrusion 48 of the circuit board 250. The protrusion 48 of the circuit board 250 may be disposed, connected, or placed in the groove 28 in the base 210.

[0416] Reference Figure 13a and Figure 13b The base 210 may include corner areas (or “edge areas”) 212 corresponding to the corners of the cover member 300. In one example, the base 210 may include four corner areas 212.

[0417] The base 210 may include a corner area 212, which has a first surface 21A. The first surface 21A has a first height difference H1 with the upper surface 21 of the base 210 in the optical axis direction.

[0418] The corner area 212 of the base 210 may be provided with a step portion 212A to avoid spatial interference with the elastic connection portion 25 (25-1 to 25-4) of the circuit board 250.

[0419] Due to the stepped portion 212A, each of the elastic connecting portions 25-1 to 25-4 may have a uniform gap with the base 210, thereby enabling OIS operation.

[0420] In one example, corner area 212 may be the area of ​​base 210 that includes corner 20A of base 210 and is adjacent to corner 20A.

[0421] The step portion 212A may include a first surface 21A, which has a first height difference H1 with the upper surface 21 of the base 210 in the optical axis OA direction. In one example, the upper surface 21 of the base 210 may be a surface that faces and contacts or is in close contact with the lower surface of the circuit board 250.

[0422] In one example, from the lower surface 22 of the base 210 (refer to...) Figure 17 The distance from the base 210 to the first surface 21A can be shorter than the distance from the lower surface 22 of the base 210 to the upper surface 21 of the base 210.

[0423] In addition, the step portion 212A may also include a second surface 21B, which has a second height difference H2 with the upper surface 21 of the base 210 in the direction of the optical axis OA.

[0424] The distance from the lower surface 22 of the base 210 to the second surface 21B of the base 210 can be shorter than the distance from the lower surface 22 of the base 210 to the upper surface 21 of the base 210.

[0425] Furthermore, the distance from the lower surface 22 of the base 210 to the second surface 21B of the base 210 can be longer than the distance from the lower surface 22 of the base 210 to the first surface 21A of the base 210.

[0426] In one example, the first height difference H1 can be greater than the second height difference H2 (H1 > H2).

[0427] In one example, each of the first surface 21A and the second surface 21B may be parallel to the upper surface 21 or the lower surface 22 of the base 210, but the invention is not limited thereto. In another embodiment, each of the first surface 21A and the second surface 21B may not be parallel to the upper surface 21 or the lower surface 22 of the base 210. Each of the first surface 21A and the second surface 21B may be a plane, but the invention is not limited thereto. In another embodiment, at least one of the first surface and the second surface may be a curved surface, or may include a curved surface.

[0428] Furthermore, the step portion 212A may also include a third surface 21C that interconnects the first surface 21A and the second surface 21B of the base 210. Additionally, the step portion 212A may also include a fourth surface 21D that interconnects the second surface 21B of the base 210 with the upper surface 21 of the base 210.

[0429] In one example, each of the third surface 21C and the fourth surface 21D of the base 210 may be perpendicular to the upper surface 21 of the base 210, but the invention is not limited thereto. In another embodiment, each of the third surface and the fourth surface of the base 210 may be an inclined surface that is tilted at a predetermined angle relative to the upper surface 21 of the base 210.

[0430] like Figure 13bAs shown, the first surface 21A can be disposed in the middle of the corner area 212, and the second surface 21B can be disposed on each side of the first surface 21A. In one example, the step portion 212A may include a first surface 21A and a second surface 2B, the second surface 2B including a second-1 surface 21B1 and a second-2 surface 21B2, the second-1 surface 21B1 being located on one side of the first surface 21A, and the second-2 surface 21B2 being located on the other side of the first surface 21A.

[0431] In another embodiment, the corner area 212 of the base 210 may be provided with at least one first surface and at least one second surface.

[0432] The stepped portion 212A may overlap with each of the elastic connecting portions 25-1 to 25-4 of the circuit board 250, which will be described later, in the optical axis direction.

[0433] The step portion 212A can be used to prevent or avoid spatial interference between the support members 220-1 to 220-4, the elastic connection portions 25-1 to 25-4, the adhesive member (or solder 902) for connecting the support members 220-1 to 220-4 to the elastic connection portions 25-1 to 25-4, and the base 210.

[0434] In addition, the damper can be disposed between the step portion 212A and each of the elastic connection portions 25-1 to 25-4, and the step portion 212A can be used to accommodate or support the damper.

[0435] In addition, such as Figure 17 As shown, since the corner area 212 of the base 210 does not have an opening structure, foreign objects generated during the soldering of the circuit board 250 to the support member 220 can be collected by means of the step portion 212A, and the performance and reliability of the image sensor of the camera module can be prevented from being degraded due to foreign objects.

[0436] Furthermore, in the case of a lens moving device with an opening structure at the corner of the base 210, additional steps may be required to block or seal the opening structure, which could increase manufacturing costs. However, this embodiment avoids the increase in manufacturing costs caused by such additional steps.

[0437] In another embodiment, a groove recessed from the upper surface 21 of the base 210 may be formed in the corner area 212 of the base 210 instead of the step portion 212A.

[0438] Figure 14A base 210-1 according to another embodiment is shown. The corner area 212 of the base 210-1 may include a step portion 212A and a guide portion 218, which protrudes from a first surface 21A of the step portion 212A in an upward direction or optical axis direction to surround the corner area 212.

[0439] The corner area 212 can be located inside the guide section 218.

[0440] The upper surface or upper end of the guide portion 218 may be located higher than the second surface 21B of the step portion 212A. In one example, the upper surface or upper end of the guide portion 218 may be located higher than the upper surface of the base 210-1. In one example, the upper surface or upper end of the guide portion 218 may be located higher than the upper surface of each of the elastic connecting portions 25-1 to 25-4.

[0441] The guide portion 218 can guide the placement or setting of the second damper 310A, which will be described later. Each of the resilient connecting portions 25-1 to 26-4 can be disposed inside the guide portion 218.

[0442] In addition, the base 210 may have mounting grooves 215-1 and 215-2 formed in its upper surface to allow the second position sensor 240 to be mounted therein.

[0443] In one example, the first mounting groove 215-1 in the base 210 may be formed adjacent to the escape portion 212-3 provided at one corner of the base 210, and the second mounting groove 215-2 in the base 210 may be formed adjacent to another escape portion 212-4 provided at another corner of the base 210.

[0444] In one example, a first mounting groove 215-1 in the base 210 may be formed in the upper surface of the base 210, thereby located between the escape portion 212-3 and the protrusion 19, and a second mounting groove 215-2 may be formed in the upper surface of the base 210, thereby located between another escape portion 212-4 and the protrusion 19.

[0445] In addition, in one example, the base 210 may have a mounting portion (not shown) formed in its lower surface to allow the filter 610 of the camera module 200 to be mounted therein.

[0446] Additionally, the base 210 may have a protrusion 19 arranged around the opening C3 on its upper surface for connecting to the opening C2 in the circuit board 250 and the opening C1 in the circuit component 231.

[0447] The protrusion 19 of the base 210 may have the same shape as the opening C3, such as a circle, but the invention is not limited thereto. In one example, the protrusion 19 may have a single circular shape, but the invention is not limited thereto. The protrusion may include multiple portions spaced apart from each other.

[0448] The base 210 may include a protrusion 32 that protrudes from its upper surface to connect to a connection groove 33 in the circuit board 250.

[0449] In one example, the connecting groove 33 in the circuit board 250 may be formed in the inner surface of the circuit board 250 defined by the opening C2, thereby recessing from the inner surface of the circuit board 250. Furthermore, the protrusion 32 of the base 210 may correspond to or face the connecting groove 33 in the circuit board 250 in the optical axis direction. The protrusion 32 may have a shape corresponding to or consistent with the shape of the connecting groove 33 in the circuit board 250. In one example, the protrusion 32 may be continuous with the outer surface of the protrusion 19 of the base 210.

[0450] The second coil 230 can be disposed on the circuit board 250, and the OIS position sensors 240a and 240b can be disposed in the mounting slots 215-1 and 215-2 in the base 210 located below the circuit board 250.

[0451] The second position sensor 240 may include a first OIS position sensor 240a and a second OIS position sensor 240b. OIS position sensors 240a and 240b can detect the displacement of the OIS operation unit in a direction perpendicular to the optical axis. Here, the OIS operation unit may include an AF operation unit and components mounted to the housing 140.

[0452] In one example, the OIS operation unit may include an AF operation unit and a housing 140. In some embodiments, the OIS operation unit may include a first magnet 130.

[0453] The circuit board 250 can be disposed on the upper surface 21 of the base 210, and can be formed with an opening C2 corresponding to the opening in the spool 110, the opening in the housing 140 and / or the opening C3 in the base 210. The opening C2 in the circuit board 250 can be a through hole.

[0454] The circuit board 250 may include: a body 252 disposed on the upper surface 21 of the base 210 and having an opening C2 formed thereon; and at least one terminal portion 253 extending from the body 252 by bending.

[0455] The main body 252 may have a shape that is consistent with or corresponds to the shape of the upper surface of the base 210, such as a rectangle.

[0456] Terminal portion 253 can be bent and extended from the upper surface of body 252 to the outer surface of base 210. Terminal portion 253 may include a plurality of terminals 251-1 to 251-n (n is a natural number greater than 1 (n>1)) or pins for receiving electrical signals from the outside.

[0457] In one example, refer to Figure 15 The circuit board 250 may include two terminal portions 253 facing each other or located in opposite positions. However, the invention is not limited thereto, and the number of terminal portions 253 may be one or more.

[0458] The second coil 230 can be positioned below the tube 110.

[0459] In one example, the second coil 230 may be disposed below the housing 140. Alternatively, in another example, the second coil 230 may be disposed below the lower elastic member 160. The second coil 230 may also be disposed on the circuit board 250.

[0460] The second coil 230 may include coil units corresponding to or facing the magnets 130-1 to 130-4 disposed in the housing 140. In one example, coil units 230-1 to 230-4 may be disposed on a circuit board 250.

[0461] In one example, the second coil units 230-1 to 230-4 may face or overlap with the magnets 130-1 to 130-4 disposed on the corners 142-1 to 142-4 of the housing 140 in the optical axis direction.

[0462] In one example, the second coil 230 may include a circuit member 231 and a plurality of coil units 230-1 to 230-4 formed on the circuit member 231. Here, the circuit member 231 may be referred to as a "board", "circuit board" or "coil board". In another embodiment, the circuit member 231 may be removed, and the second coil 230 may include coil units 230-1 to 230-4.

[0463] The circuit component 231 may have a shape that is consistent with or corresponds to the shape of the upper surface of the base 210 (or circuit board 250), such as a rectangle.

[0464] In one example, four coil units 230-1 to 230-4 may be disposed or formed at the corners or corner areas of a polygonal (e.g., rectangular) circuit member 231. Each of the coil units 230-1 to 230-4 may have a shape corresponding to or consistent with the shape of the magnets 130-1 to 130-4 in the optical axis direction.

[0465] In one example, when viewed from above, each of the coil units 230-1 to 230-4 may have the shape of a closed curve that rotates about the optical axis, such as a ring.

[0466] Each of the coil units 230-1 to 230-4 may be implemented as a coil block composed of fine pattern (FP) coils, but the invention is not limited thereto.

[0467] In an embodiment where the magnet is disposed on the side of the housing 140, the coil unit of the second coil may be disposed parallel to the side of the circuit member 231 and may have a shape that corresponds to or is consistent with the shape of the magnet disposed on the side of the housing.

[0468] In one example, the second coil 230 may include two coil units 230-1 and 230-3 for the second direction and two coil units 230-2 and 230-4 for the third direction, but the invention is not limited thereto.

[0469] In one example, two coil units 230-1 and 230-3 may be disposed in two corner areas of the circuit member 231 facing each other in the first diagonal direction of the circuit member 231, and the remaining two coil units 230-2 and 230-4 may be disposed in the remaining two corner areas of the circuit member 231 facing each other in the second diagonal direction of the circuit member 231.

[0470] The first diagonal direction and the second diagonal direction can be perpendicular to each other. In one example, the first diagonal direction can be the X-axis direction, and the second diagonal direction can be the Y-axis direction.

[0471] In one example, coil units 230-1 and 230-3 for the second direction can generate electromagnetic forces in the same direction due to their interaction with corresponding magnets 130-1 and 130-3 in the optical axis direction. Furthermore, coil units 230-2 and 230-4 for the third direction can also generate electromagnetic forces in the same direction due to their interaction with corresponding magnets 130-2 and 130-4 in the optical axis direction.

[0472] In another embodiment, the second coil 230 may include a coil unit for a second direction and a coil unit for a third direction, or may include four or more coil units.

[0473] The second coil 230 can be electrically connected to the circuit board 250. In one example, the second coil 230 can be electrically connected to terminal 251 of the circuit board 250.

[0474] Power or drive signals can be supplied from circuit board 250 to the second coil 230. The power or drive signals supplied to the second coil 230 can be DC signals, AC signals, or signals including both DC and AC components, and can be current-type or voltage-type.

[0475] Due to the interaction between magnets 130-1 to 130-4 and second coils 230-1 to 230-4 that are provided with drive signals, housing 140 moves upward in a second direction and / or a third direction, for example, in the X-axis direction and / or the Y-axis direction, thereby enabling hand shaking correction.

[0476] Reference Figure 15 and Figure 16 The second coil 230 may include terminals 30A to 30D to receive drive signals from the circuit board 250.

[0477] In one example, circuit member 231 may include four terminals 30A to 30D. In one example, the four terminals 30A to 30D may be arranged or disposed on the lower surface of circuit member 231. Here, the lower surface of circuit member 231 may be the surface facing the upper surface of circuit board 250.

[0478] In one example, four terminals 30A to 30D may be formed adjacent to at least one side surface of the circuit member 231. In another example, two terminals 30B and 30D of the circuit member 231 may be disposed on the lower surface of the circuit member 231 adjacent to the first side surface of the circuit member 231, and may be located between the third coil unit 230-1 and the fourth coil unit 230-4.

[0479] The remaining two terminals 30A and 30C of the circuit member 231 may be disposed on the portion of the lower surface of the circuit member 231 adjacent to the second side surface of the circuit member 231, and may be located between the first coil unit 230-2 and the second coil unit 230-2. In one example, the first side surface and the second side surface of the circuit member 231 may face each other or may be located in opposite positions.

[0480] In one example, the first coil unit 230-1 and the third coil unit 230-4 can be connected in series with each other, and the second coil unit 230-2 and the fourth coil unit 230-4 can be connected in series with each other.

[0481] In one example, one end of the first coil unit 230-1 may be electrically connected to the first terminal 30A of the circuit member 231, one end of the third coil unit 230-3 may be electrically connected to the second terminal 30B of the circuit member 231, and the other ends of the first coil unit 230-1 and the third coil unit 230-3 may be electrically connected to each other. In another example, the other ends of the first coil unit 230-1 and the third coil unit 230-3 may be electrically connected to each other via a first conductive pattern or a first wiring formed in the circuit member 231.

[0482] Furthermore, in one example, one end of the second coil unit 230-1 can be electrically connected to the third terminal 30C of the circuit member 231, one end of the fourth coil unit 230-4 can be connected to the fourth terminal 30D of the circuit member 231, and the other ends of the third coil unit 230-3 and the fourth coil unit 230-4 can be electrically connected to each other. In one example, the other ends of the third coil unit 230-3 and the fourth coil unit 230-4 can be electrically connected to each other via a second conductive pattern or a second wiring formed in the circuit member 231.

[0483] The circuit board 250 may include pads 27a to 27d for electrical connection to coil units 230-1 to 230-4. Here, pads 27a to 28d may be referred to as “terminals” or “joints”.

[0484] The circuit board 250 may include pads 27a to 27d that correspond to or face the first terminal 30A to the fourth terminal 30D of the circuit member 231 in the optical axis direction.

[0485] In one example, pads 27a to 27d of the circuit board 250 may be arranged or disposed on the lower surface of the circuit board 250, but the invention is not limited thereto. In another embodiment, pads may also be formed on at least one of the upper and lower surfaces of the circuit board 250.

[0486] Each of the pads 27a to 27d of the circuit board 250 may be formed with a recess to expose a portion of the corresponding terminals of the terminals 30A to 30D of the circuit component 231. Each of the pads 27a to 27d of the circuit board 250 may be connected and electrically connected to the corresponding terminals of the terminals 30A to 30D of the circuit component 231 by means of a conductive adhesive member or solder 39A.

[0487] In one example, pads 27a to 27d of the circuit board 250 may be disposed or formed on a portion of the lower surface of the circuit board 250 adjacent to at least one side surface of the circuit board 250 where the unformed terminal portion 253 is located.

[0488] In one example, two pads 27a and 27c may be disposed on the lower surface of the circuit board 250 adjacent to the first outer surface 33-1 of the circuit board 250, and the remaining two pads 27b and 27d may be disposed on the lower surface of the circuit board 250 adjacent to the second outer surface 33-2 of the circuit board 250, with the first outer surface 33-1 and the second outer surface 33-2 located opposite to each other. Furthermore, a terminal portion 253 may be disposed on each of the third outer surface 33-3 and the fourth outer surface 33-4 of the circuit board 250, with the third outer surface 33-3 and the fourth outer surface 33-4 located opposite to each other.

[0489] In one example, the two coil units 230-1 and 230-3 for the second direction can be connected in series with each other. One end of each of the coil units 230-1 and 230-3 connected in series with each other can be electrically connected to the first pad 27a of the circuit board 250, and the other end of each of the coil units 230-1 and 230-3 connected in series with each other can be electrically connected to the second pad 27b of the circuit board 250.

[0490] Furthermore, in one example, the two coil units 230-2 and 230-4 for the third direction can be connected in series with each other. One end of each of the coil units 230-2 and 230-4 connected in series with each other can be electrically connected to the third pad 27c of the circuit board 250, and the other end of each of the coil units 230-2 and 230-4 connected in series with each other can be electrically connected to the fourth pad 27d of the circuit board 250.

[0491] The first pad 27a and the second pad 27b of the circuit board 250 can be electrically connected to two corresponding terminals of terminals 251-1 to 251-n of the circuit board 250, and can provide a first drive signal to the coil units 230-1 and 230-3 connected in series with each other through the two corresponding terminals of the circuit board 250.

[0492] The third pad 27c and the fourth pad 27d of the circuit board 250 can be electrically connected to the corresponding two terminals of the terminals 251-1 to 251-n of the circuit board 250, and can provide a second drive signal to the coil units 230-2 and 230-4 connected in series with each other through the two corresponding terminals of the circuit board 250.

[0493] In another embodiment, terminals of circuit member 231 may be formed on the inner peripheral surface of circuit member 231 defined by opening C1 and / or on the portion of the lower surface of circuit member 231 adjacent to the inner peripheral surface. Furthermore, pads of circuit board 250 may be formed on the inner peripheral surface of body 252 of circuit board 250 defined by opening C2 and / or on the portion of the lower surface of body 252 of circuit board 250 adjacent to the inner peripheral surface.

[0494] Although Figure 13a The diagram shows a circuit pattern formed at a circuit member 231 that is separately disposed from the circuit board 250 for each of the coil units 230-1 to 230-4, such as an FP coil, but the invention is not limited thereto.

[0495] In another embodiment, circuit component 231 can be removed, and coil units 230-1 to 230-4 can be implemented as a ring coil block.

[0496] In another embodiment, the coil units 230-1 to 230-4 can be implemented as circuit patterns directly formed on the circuit board 250, such as in the form of FP coils. In this case, the circuit board 250 can be referred to as a "circuit component" or a "board". In this case, the other end of each of the support components can be connected to the circuit component (e.g., the lower surface of the circuit component), and the circuit component can include a board portion (or body) with coil units 230-1 to 230-4 formed thereon and a terminal portion with terminals formed thereon. The description of the circuit board 250 can be applied to the board portion, and the description of the terminal portion 253 of the circuit board 250 can be applied to the terminal portion.

[0497] Furthermore, as described above, at least one of the circuit components 231 and / or the circuit board 250 may be formed with holes or escape slots to avoid spatial interference with the support component 220.

[0498] To avoid spatial interference with the support member 220, an escape portion 23 can be formed at the corner of the circuit member 231. The escape portion 23 can be formed by chamfering the corner of the circuit member 231.

[0499] In one example, since the escape portion 23 is used to avoid spatial interference with the elastic connections 25-1 to 25-4 described later, the circuit component 231 can avoid overlapping with the elastic connections 25-1 to 25-4 in the optical axis direction by means of the escape portion 23.

[0500] In another embodiment, the escape portion of the circuit component can be formed in the shape of an escape groove.

[0501] The circuit component 231 may be formed with an escape slot 24 to avoid spatial interference with the fifth terminal B5 and the sixth terminal B6 of the circuit board 190. In one example, the escape slot 24 may be formed on one side of the circuit component 231, thereby corresponding to, facing, or overlapping the fifth terminal B5 and the sixth terminal B6 of the circuit board 190 in the optical axis direction. In one example, the escape slot 24 may be disposed between the first coil unit 230-1 and the fourth coil unit 230-4.

[0502] Each of the OIS position sensors 240a and 240b can be a Hall sensor. Any sensor of various types can be used, as long as it is capable of detecting magnetic field strength. In one example, each of the OIS position sensors 240a and 240b can be implemented as a single position detection sensor, such as a Hall sensor, or can be implemented as a driver including a Hall sensor. In the case where each of the OIS position sensors 240a and 240b is implemented as a driver including a Hall sensor, a reference can be applied. Figure 7b The description.

[0503] During the movement of the OIS operating unit in a direction perpendicular to the optical axis, each of the OIS position sensors 240a and 240b can detect the magnetic field strength of magnets 130-1 to 130-4 and can output an output signal corresponding to the detection result. The displacement of the OIS operating unit can be detected using the output signals from each of the OIS position sensors 240a and 240b, and the controller 830 or 780 can perform OIS feedback hand shakiness correction using the output signals from the OIS position sensors 240a and 240b.

[0504] In one example, the first OIS position sensor 240a may overlap with a first line extending from a first corner of the circuit board 250 to the center of the opening C2 in the circuit board 250. The second OIS position sensor 240b may overlap with a second line extending from a second corner of the circuit board 250 to the center of the opening C2 in the circuit board 250.

[0505] In one example, the center of the first OIS position sensor 240a may be aligned with or overlap with the first line, and the center of the second OIS position sensor 240b may be aligned with or overlap with the second line. The first line and the second line may be perpendicular to each other.

[0506] The terminal portion 253 of the circuit board 250 may be provided with terminals 251-1 to 251-n.

[0507] Multiple terminals 251-1 to 251-n mounted on the terminal section 253 of the circuit board 250 can send or receive signals SCL, SDA, VDD and GND to communicate data with the first position sensor 190, and can provide drive signals to the OIS position sensors 240a and 240b and output signals to the outside.

[0508] In this embodiment, the circuit board 250 may be implemented as a flexible printed circuit board (FPCB). Alternatively, the terminals of the circuit board 250 may be formed directly on the surface of the base 210 using methods such as surface electrodes.

[0509] Since the embodiment is configured such that the drive signal is provided directly from the first position sensor 170 to the first coil 120, the number of support members can be reduced and the electrical connection structure can be simplified compared to the case where the drive signal is provided directly to the first coil 120 through the circuit board 250.

[0510] In addition, since the first position sensor 170 can be implemented as a driver IC capable of measuring temperature, the output from the Hall sensor can be compensated so that the output variation that varies with temperature can be minimized, or the output can have a constant slope relative to temperature variation, thereby improving the accuracy of AF operation regardless of temperature variation.

[0511] The receiving space formed by the cover member 300 and the base 210 contains the wire spool 110, the first coil 120, the first magnet 130, the housing 140, the upper elastic member 150, the lower elastic member 160, the first position sensor 170, the second magnet 180, the circuit board 190, the support member 220, the second coil 230, the second position sensor 240, and the circuit board 250.

[0512] The cover member 300 can be formed in the shape of a box having an open lower portion and including an upper plate 301 and a side plate 302. The lower portion of the cover member 300 (e.g., the lower portion of the side plate 302) can be connected to the base 210 (e.g., step 211 and / or escape portions 212-1 to 212-4). The upper plate 301 of the cover member 300 can be circular or polygonal, such as rectangular or octagonal, but the invention is not limited thereto.

[0513] The cover member 300 may have an opening 303 formed in its upper plate 301 to expose the lens (not shown) connected to the coil 110 to external light. The cover member 300 may be made of a non-magnetic material such as SUS to prevent it from being attracted to the first magnet 130. Alternatively, the cover member 300 may be made of a magnetic material to serve as a yoke for increasing the electromagnetic force between the first coil 120 and the first magnet 130.

[0514] To reduce the length of the path for transmitting power signals GND and VDD to the first position sensor 170, the following structure can be provided.

[0515] First, the first terminal B1 and the second terminal B2 of the circuit board 190, which is provided with power signals GND and VDD, are electrically connected to the first support member 220-1 and the second support member 220-1, which are disposed on the two corners 142-1 and 142-2 adjacent to the first side 141-1 of the housing 140 on which the first position sensor 170 is disposed, thereby shortening the path.

[0516] Furthermore, the first terminal B1 and the second terminal B2 of the circuit board 190 are disposed on the main body S1 of the circuit board 190, thereby shortening the path.

[0517] Furthermore, the first terminal B1 of the circuit board 190 is disposed on one end of the circuit board 190, such that the first terminal B1 overlaps with the first corner 142-1 of the housing 140 in the optical axis direction, and the second terminal B2 of the circuit board 190 is disposed on the other end of the circuit board 190, such that the second terminal B2 overlaps with the second corner 142-2 of the housing 140 in the optical axis direction, thereby shortening the path.

[0518] Furthermore, the distance between the first terminal B1 of the circuit board 190 and the first support member 220-1 (e.g., the shortest distance) is shorter than the distance between the third terminal B3 of the circuit board 190 and the first support member 220-1 (e.g., the shortest distance) and the distance between the fourth terminal B4 of the circuit board 190 and the first support member 220-1 (e.g., the shortest distance).

[0519] Furthermore, the spacing distance (e.g., the shortest spacing distance) between the second terminal B2 of the circuit board 190 and the second support member 220-2 is shorter than the spacing distance (e.g., the shortest spacing distance) between the third terminal B3 of the circuit board 190 and the second support member 220-2, and the spacing distance (e.g., the shortest spacing distance) between the fourth terminal B4 of the circuit board 190 and the second support member 220-1.

[0520] Because of the path shortening caused by the above configuration, the length of each of the first extension P1 and the second extension P2 can be reduced, thereby reducing the path resistance (e.g., the resistance of the first upper elastic unit 150-1 and the second upper elastic unit 150-2).

[0521] Furthermore, each of the first upper elastic unit 150-1 connected to the first terminal B1 of the circuit board 190 and the second upper elastic unit 150-2 connected to the second terminal B2 includes a first outer frame connected to the housing 140, but does not include the first inner frame 151 or the first frame connection portion, thereby reducing its resistance compared to the second upper elastic unit 150-3 and the fourth upper elastic unit 150-4.

[0522] In the embodiment with the above structure, since the path length of the power signals GND and VDD to the first position sensor 170 is reduced, the resistance of the path (e.g., the resistance of the first upper elastic unit 150-1 and the second upper elastic unit 150-2) can be reduced, thereby preventing the power signals GND and VDD from attenuating, reducing power consumption, and reducing the driving voltage of the driver IC of the first position sensor 170.

[0523] In an embodiment, in order to facilitate welding for electrically connecting the upper elastic units 150-1 to 150-4 to the first extension P1 to the fourth extension P4 and thereby improve welding efficiency, the first terminal P1 to the sixth terminal P6 can be provided on the second surface 19a of the circuit board 190.

[0524] If the first terminals B1 to the sixth terminals B6 are located on the first surface 19b of the circuit board 190, soldering may be difficult to perform, thus degrading soldering efficiency. In addition, foreign matter (e.g., contaminants) generated by soldering may be introduced into the lens moving device 100, causing the lens moving device to malfunction.

[0525] Since the third terminal B3 and the fourth terminal B4 are disposed between the first terminal B1 and the second terminal B2, and the circuit board 190 extends or protrudes to the first corner 142-1 and the second corner 142-2 of the housing 140 to shorten the path, a portion of each of the third upper elastic unit 150-3 and the fourth upper elastic unit 150-3 (e.g., each of the third extension P3 and the fourth extension P4) can pass through the circuit board 190 and connect to the corresponding terminals in the third terminal B3 and the fourth terminal B4.

[0526] The fifth terminal B5 and the sixth terminal B6 of the circuit board 190 can be disposed on the extension S2 of the circuit board 190 to facilitate connection with the lower elastic units 160-1 and 160-2.

[0527] In this embodiment, since the magnetic field interference between the first magnet 180 and the second magnet 185 and the first magnet 130 is mitigated, the reduction of the AF driving force due to magnetic field interference can be prevented, thereby obtaining the desired AF driving force without the need for a separate magnetic yoke.

[0528] As described above, the embodiments can reduce the number of support members, and therefore the size of the lens moving device can be reduced.

[0529] Furthermore, by reducing the number of support components, the resistance of the support components can be reduced, thereby reducing power consumption and improving the sensitivity of OIS operation.

[0530] Furthermore, although the number of support members is reduced, the thickness of the support members can be increased to achieve the predetermined elasticity. Due to the increased thickness of the support members, the impact of external impacts on the OIS operating unit can be reduced.

[0531] Figure 18a yes Figure 13a The perspective view of the circuit board 250 shown. Figure 18b yes Figure 18a Enlarged view of the elastic connection portions 25-1 to 25-4 of the circuit board 250 shown.

[0532] Reference Figure 18a and Figure 18b The circuit board 250 may include resilient connecting portions 25-1 to 25-4 connected to the support member 220. The resilient connecting portions 25-1 to 25-4 may extend from the corner area of ​​the circuit board 250 and the other end of the support member 220-1 to 220-4 may be connected thereto.

[0533] The elastic connecting parts 25-1 to 25-4 can be referred to as "buffer parts", "elastic parts" or "spring parts".

[0534] The flexible connecting parts 25-1 to 25-4 can be provided on the corners or corner areas of the main body 252 of the circuit board 250.

[0535] The flexible connecting portions 25-1 to 25-4 can extend from the body 252 of the circuit board 250 to the support members 220-1 to 220-4, and can be connected to the other end of the support members 220-1 to 220-4 by solder 902 or conductive adhesive member.

[0536] The circuit board 250 may include an escape portion 125A formed at a corner or corner area of ​​the body 252 to avoid spatial interference with the support member 220. In one example, the escape portion 125A may be formed by chamfering the corner or corner area of ​​the body 252, but the invention is not limited thereto. The escape portion of the circuit board 250 may be formed into any shape among various shapes that avoid interference with the support member 220.

[0537] The circuit board 250 may have an external connection surface (or a fifth external surface) 33-5 at the corner or corner area of ​​its body 252 for interconnecting two adjacent external surfaces 33-1 and 33-3, 33-2 and 33-3, 33-2 and 33-4, and 33-4 and 33-1.

[0538] The flexible connecting parts 25-1 to 25-4 can extend and protrude from the outer connecting surface 33-5.

[0539] In one example, each of the resilient connecting portions 25-1 to 25-4 may include a connecting portion 60A and a connecting portion 60B, with the other end of the corresponding support member of the support members 220-1 to 220-4 connected to the connecting portion 60A, and the connecting portion 60B connecting the first connecting portion 60A to the body 252 of the circuit board 250. The connecting portion 60B may extend from the body 252 to connect to the connecting portion 60A and may be referred to as an "extension".

[0540] The connecting part 60A can be referred to as the "first part", and the connecting part 60B can be referred to as the "second part".

[0541] The elastic connecting portions 25-1 to 25-4 can be elastic members. In one example, similar to the upper elastic member 150 and the lower elastic member 160, the elastic connecting portions 25-1 to 25-4 can be implemented as leaf springs, but the invention is not limited thereto.

[0542] The elastic connecting portions 25-1 to 25-4 may include conductive material, and the support members 220-1 to 220-4 may be electrically connected to the terminals 251 of the circuit board 250.

[0543] Each of the elastic connecting portions 25-1 to 25-4 may be formed with a hole 250a to allow a corresponding support member of support members 220-1 to 220-5 to pass through the hole 250a. In one example, the hole 250a for the corresponding support member of support members 220-1 to 220-5 to pass through may be formed in the connecting portion 60A. The hole 250a may be a through hole formed through the connecting portion 60A.

[0544] In one example, the connector 60A may include a hole 250a. Additionally, in one example, the connector 60A may include a portion of the resilient connector 25-1 to 25-4 adjacent to the hole 250a, representing a portion of the resilient connector 25-1 to 25-4 where a solder or conductive adhesive member is disposed.

[0545] The connecting portion 60B may be formed as a bend or fold at least once. The connecting portion 60B may include a zigzag segment, at least one bent segment, or at least one folded segment.

[0546] In one example, the connecting portion 60B may include: a first connecting portion 61 (or "first extension") extending or protruding from a region of the corner of the body 252; a second connecting portion (or "second extension") extending or protruding from another region of the corner of the body 252 and connected to the first connecting portion 61; and a third connecting portion 63 (or "third extension") connected to at least one of the first connecting portion 61 and the second connecting portion 62 and connected to the connecting portion 60A.

[0547] In one example, the first connection 61 may extend from a first region 37-1 of the outer connection surface 33-5 adjacent to one of the two adjacent outer surfaces (e.g., 33-1 and 33-3) of the outer surface of the body 252 (e.g., 33-3).

[0548] In one example, the first connecting portion 61 may be linear, such as a straight line. In another embodiment, the first connecting portion may be a curve that bends at least once. In one example, the first connecting portion may include a zigzag segment, at least one curved segment, or at least one bent segment. In yet another embodiment, the first connecting portion may be linear, including curved segments and straight segments.

[0549] Furthermore, in one example, the second connection portion 62 may extend from the second region 37-2 of the outer connection surface 33-5 adjacent to another of the two adjacent outer surfaces (e.g., 33-1 and 33-3) on the outer surface of the body 252, and may be connected to the first connection portion 61.

[0550] In one example, the second connecting portion 62 can be linear, such as a straight line. In another embodiment, the second connecting portion can be a curve that bends at least once. In one example, the second connecting portion can include a zigzag segment, at least one curved segment, or at least one bent segment. In yet another embodiment, the second connecting portion can be linear, including curved segments and straight segments.

[0551] In one example, the third connecting part 63 can connect the portion where the first connecting part 61 and the second connecting part 62 intersect to the connecting part 60A.

[0552] In one example, the third connecting portion 63 can be linear, such as a straight line. In another embodiment, the third connecting portion can be a curve that bends at least once. In one example, the third connecting portion can include a zigzag segment, at least one curved segment, or at least one bent segment. In yet another embodiment, the third connecting portion can be linear, including curved segments and straight segments.

[0553] In one example, a single contact can be formed between the connecting part 60A and the connecting part 60B through the third connecting part 63.

[0554] In one example, the other end of each of the support members 220-1 to 220-4 connected to the connecting portion 60A may be located between the corner or corner area of ​​the connecting portion 60B and the main body 252. In another example, the other end of each of the support members 220-1 to 220-4 connected to the connecting portion 60A may be located inside the connecting portion 60B.

[0555] In one example, each of the elastic connecting portions 25-1 to 25-4 may include a portion whose width increases from one end of the connecting portion 60B to the connecting portion 60A and then decreases. One end of the connecting portion 60B may be the portion where the connecting portion 60B intersects with the body 252.

[0556] The connecting part 60B may include a portion whose width gradually decreases from the corner or corner area of ​​the main body 252 toward the corresponding support members 220-1 to 220-4.

[0557] In one example, the width W1 of the first connecting portion 61 can be equal to the width W2 of the second connecting portion 62. This is to allow the elastic connecting portions 25-1 to 25-4 to support the OIS operating unit in a balanced state. In one example, the first connecting portion 61 and the second connecting portion 62 can be symmetrical about each other with respect to the third connecting portion 63. In another example, the widths of the first connecting portion 61 and the second connecting portion 62 can be symmetrical about each other with respect to the third connecting portion 63.

[0558] In another embodiment, the width W1 of the first connecting portion 37-1 may be different from the width W2 of the second connecting portion 37-2. In one example, the width W1 of the first connecting portion 37-1 may be smaller than the width W2 of the second connecting portion 37-2. In another embodiment, the width W1 of the first connecting portion 37-1 may be larger than the width W2 of the second connecting portion 37-2.

[0559] The first connecting portion 61 may include a portion whose width decreases from one end of the first connecting portion 61 (or the corner of the main body 252) toward the support member 220. Furthermore, the second connecting portion 62 may include a portion whose width decreases from one end of the second connecting portion 62 (or the corner of the main body 252) toward the support member 220.

[0560] The width W1 of the first connecting portion 61 can gradually decrease from one end of the first connecting portion 61 to the other end of the first connecting portion 61.

[0561] One end of the first connecting part 61 can be a part connected to the main body 252 of the circuit board 250, and the other end of the first connecting part 61 can be a part connected to the second connecting part 62 (and / or the third connecting part 64).

[0562] In one example, the width of one end of the first connecting portion 61 may be larger than the width of the other end of the first connecting portion 61, but the invention is not limited thereto. In another embodiment, the two widths may be equal to each other.

[0563] The width W2 of the second connecting portion 62 can gradually decrease from one end of the second connecting portion 62 to the other end of the second connecting portion 62.

[0564] One end of the second connecting part 62 can be a part connected to the main body 252 of the circuit board 250, and the other end of the second connecting part 62 can be a part connected to the first connecting part 61 (and / or the third connecting part 64).

[0565] In one example, the width of one end of the second connecting portion 62 may be larger than the width of the other end of the second connecting portion 62, but the invention is not limited thereto. In another embodiment, the two widths may be the same.

[0566] In another example, the width of one end of the first connecting portion 61 may be larger than the width of the other end of the first connecting portion 61, and the width of one end of the second connecting portion 62 may be larger than the width of the other end of the second connecting portion 62. The reason why the width of one end of each of the first connecting portion 61 and the second connecting portion 62 is set to be larger than the width of the other end of each of the first connecting portion 61 and the second connecting portion 62 is to enable the elastic connecting portions 25-1 to 25-4 to be stably supported by the body 252 of the circuit board 250, thereby increasing the elastic force of the elastic connecting portion in the optical axis direction and reducing the elastic force of the elastic connecting portion in the direction perpendicular to the optical axis, thereby stably supporting the large-diameter lens.

[0567] In one example, the width W3 of the third connecting portion 63 can be larger than the width W1 of the first connecting portion 61 and the width W2 of the second connecting portion 62 (W3 > W1 and W3 > W2). As described later, the first damper 310 can be disposed between the third connecting portion 63 and the main body 252 (e.g., escape portion 125A) to interconnect the third connecting portion 63 and the main body 252. Since the width W3 is larger than the widths W1 and W2 (W3 > W1 and W3 > W2), the contact area between the third connecting portion 63, the main body 252 and the first damper 310 can be increased, thereby reducing the quality factor (Q) used to determine the resonant frequency of the frequency response characteristics based on OIS operation. Due to the reduced quality factor, the gain value of the frequency response characteristics at the first resonant frequency can be reduced, and the second and third resonant frequencies can have high values, thereby reducing the oscillation phenomenon of the OIS operation unit, improving the accuracy of OIS feedback operation, and thus improving the imaging quality of the camera module.

[0568] In another embodiment, the width W3 of the third connecting portion 63, the width W1 of the first connecting portion 61, and the width W2 of the second connecting portion 62 may be equal to each other. In another embodiment, the width W3 of the third connecting portion 63 may be smaller than at least one of the width W1 of the first connecting portion 61 and the width W2 of the second connecting portion 62.

[0569] Here, the width of each of the first connecting portion 61 to the third connecting portion 63 can be the length of each of the first connecting portion 61 to the third connecting portion 63 in a direction perpendicular to its length direction (or extension direction).

[0570] The width of the connecting portion 60A can be equal to the width W3 of the third connecting portion 63. In one example, the width of the connecting portion 60A can be larger than the width W1 of the first connecting portion 61 and the width W2 of the second connecting portion 62. This is because the connecting portion 60A has a hole 250a that connects to the other end of the corresponding support member in the support members 220-1 to 220-4, and a sufficiently large area is required to connect to the UI support member in the support members 220-1 to 220-4 via solder 902 or conductive adhesive. Furthermore, this is to ensure the contact area between the connecting portion 60A and the first damper 310.

[0571] In another embodiment, the width of the connecting portion 60A may be larger than the width of the third connecting portion 64. In yet another embodiment, the width of the connecting portion 60A may be smaller than the width of the third connecting portion 64.

[0572] In one example, the widths W1, W2, and W3 of the elastic connection 25-1 can be larger than the width W11 of the connection 530 of the outer frame 152 of the upper elastic member 150 (see reference). Figure 10 ).

[0573] The thickness T1 of each of the elastic connecting parts 25-1 to 25-4 can be smaller than the thickness T2 of the body 252 of the circuit board 250 (T1 < T2).

[0574] The thickness T1 of each of the elastic connecting parts 25-1 to 25-4 can be the length of each of the elastic connecting parts 25-1 to 25-4 in the optical axis direction, and the thickness of the main body 252 can be the length of the main body 252 in the optical axis direction.

[0575] In one example, the spring constant of each of the elastic connections 25-1 to 25-4 may be greater than the spring constant of the upper elastic member 150.

[0576] In one example, the spring constant of each of the elastic connections 25-1 to 25-4 in the direction perpendicular to the optical axis (e.g., the X-axis direction or the Y-axis direction) may be greater than the spring constant of the upper elastic member 150 in the direction perpendicular to the optical axis.

[0577] In another example, the spring constant of each of the elastic connections 25-1 to 25-4 in the optical axis direction (e.g., the Z-axis direction) may be greater than the spring constant of the upper elastic member 150 in the optical axis direction.

[0578] The elastic connecting parts 25-1 to 25-4, the connecting part 60A, the connecting part 60B, the first connecting part 61, the second connecting part 62 or the third connecting part 63 may be referred to as "buffer parts", "elastic parts", "spring parts" or "suspension parts".

[0579] In typical lens moving devices where the support member is directly connected to the main body of the circuit board, the circuit component of the second coil, or the base, the large-diameter lens applies significant stress and fatigue load to the support member. Furthermore, in this case, because one end of the support member is connected to the upper elastic member while the other end is fixed to the main body of the circuit board, the circuit component of the second coil, or the base, which serves as a fixing part, stress concentrates at the other end of the support member, leading to deformation of the support member.

[0580] By reducing the spring constant of the upper elastic member, the stress applied to the support member can be reduced. However, this may increase the posture difference of the OIS operating unit due to gravity.

[0581] In addition, when the spring constant of the upper elastic member is reduced in order to reduce stress, the shape freedom of the upper elastic member may be reduced, which may cause the frequency response characteristics of OIS operation to deteriorate and the OIS operation unit to oscillate.

[0582] However, in this embodiment, by means of the elastic connection portions 25-1 to 25-4 of the elastic members, each of which is directly connected to the other end of the corresponding support member in the support member 220, the stress applied to the support member due to the large-diameter lens can be dispersed and the fatigue accumulation of the support member can be eliminated.

[0583] That is, since the connecting portion 60A of each of the elastic connecting portions 25-1 to 25-4 is spaced apart from the main body 252, each of the support members 220-1 to 220-4 connected to the connecting portion 60A according to the embodiment can be easily moved in the first direction. Compared with ordinary support members fixed to the main body of the circuit board, the support members 220-1 to 220-4 according to the embodiment can be moved more easily in the first direction. Therefore, the accuracy of hand tremor correction is improved, stress can be dispersed relative to drops and impacts, and thus deformation and breakage of the support members 220-1 to 220-4 can be prevented.

[0584] Furthermore, since each of the elastic connecting portions 25-1 to 25-4 has a shape that bends at least once, the total length of each of the elastic connecting portions 25-1 to 25-4 can be increased. Therefore, this embodiment can disperse the stress applied to the upper elastic member 150 and / or the support member 220, and can prevent damage to the elastic connecting portions caused by impacts and stresses applied to the upper elastic member 150 and / or the support member 220.

[0585] Furthermore, in this embodiment, since the elastic constant of each of the elastic connecting portions 25-1 to 25-4 is greater than the elastic constant of the upper elastic member, the strength of the elastic connecting portions 25-1 to 25-4 can be increased, and thus the posture difference of the OIS operating unit caused by gravity can be reduced.

[0586] Furthermore, since the third connecting portion 63 forms a single contact between the connecting portion 60A and the connecting portion 60B, the elastic connecting portions 25-1 to 25-4 can move more easily in the first direction, and the stress applied to the upper elastic member 150 and / or the support member 220 caused by the impact can be more effectively dispersed.

[0587] Furthermore, as described above, because the strength of the elastic connecting portions 25-1 to 25-4 is increased, this embodiment can increase the second resonant frequency of the frequency response characteristics based on OIS operation, thereby preventing oscillation of the OIS operation unit during OIS operation. In one example, the frequency response characteristics based on OIS operation can be the frequency response characteristics with respect to the output signal output from the second position sensor 240.

[0588] Figure 19a It is based on Figure 18a A perspective view of the main body 252-1 of another embodiment of the circuit board 250 shown. Figure 19b yes Figure 19a An enlarged view of the escape section 125A1 of the main body 252-1 shown. Figure 19a and Figure 19b In, with Figure 18a and Figure 18b The same reference numerals denote the same parts, and the descriptions of the same parts are simplified or omitted.

[0589] Reference Figure 19a and Figure 19b The escape portion 125A1 of the main body 252-1 of the circuit board 250 may be provided with an extension portion 41A extending to each of the directional elastic connection portions 25-1 to 25-4.

[0590] The body 252-1 may include an extension 41A extending into each of the resilient connecting portions 25-1 to 25-4. In one example, at least a portion of the extension 41A may overlap with the first surface 21A of the step portion 212A of the base 210 in the optical axis direction. The first damper 310 may connect the extension 41A of the body 252-1 to each of the resilient connecting portions 25-1 to 25-4.

[0591] Extension 41A may protrude from outer connecting surface 33-5 into each of elastic connecting portions 25-1 to 25-4. In one example, extension 41A may protrude from outer connecting surface 33-5 into connection portion 60A of each of elastic connecting portions 25-1 to 25-4.

[0592] The extension 41A may be referred to as a “protrusion” or a “damper guide”.

[0593] The extension 41A may be spaced apart from each of the elastic connecting portions 25-1 to 25-4.

[0594] The width W21 of the extension 41A can gradually decrease from the center of the extension 41A (or the center of the opening C2 in the circuit board 250) toward the connecting portion 60B. The width W21 of the extension 41A can be the length of the extension 41A in a direction perpendicular to the direction from the center of the extension 41A (or the center of the opening C2 in the circuit board 250) toward the connecting portion 60B.

[0595] The extension 41A may have a hole 41B or a groove formed at one end to increase the contact area with the first damper 310. In this case, one end of the extension 41A may be the portion adjacent to and spaced apart from the connecting portion 60A.

[0596] In one example, the hole 41B may be recessed from the connecting portion 60A into the extension portion 41A. Furthermore, the hole 41B may have an opening facing the connecting portion 60A and may have a shape corresponding to a portion of the connecting portion 60B.

[0597] In one example, at least a portion of the hole 41B may overlap with the first surface 21A of the step portion 212A of the base 210 in the optical axis direction.

[0598] At least a portion of each of the elastic connecting parts 25-1 to 25-4 can be disposed in the hole 41B through the opening in the hole 41B.

[0599] In one example, at least a portion of the connecting portion 60B may be disposed in the hole 41B, and the outer surface of the extension 41A defined by the hole 41B may face at least a portion of the connecting portion.

[0600] In one example, when viewed from above, the hole 41B can be semi-circular or semi-elliptical, but the invention is not limited thereto. In another embodiment, when viewed from above, the hole can be polygonal, such as rectangular or triangular.

[0601] In one example, with Figure 18a and Figure 18bCompared with the structure shown, due to the extension part 41A, the spacing distance between the main body 252-1 and each of the elastic connecting parts 25-1 to 25-4 can be reduced, so that the first damper 310 can be easily applied to the main body 252-1 and each of the elastic connecting parts 25-1 to 25-4.

[0602] In one example, the spacing distance d1 between the extension part 41A and the connecting part 60A can be smaller than the spacing distance d2 between the extension part 41A and the connecting part 60B (d1 < d2). In addition, in one example, the spacing distance d1 between the extension part 41A and the connecting part 60A can be smaller than the widths W1, W2, and W3 of the connecting part 60B. The reason is to facilitate the application of the first damper 310 to the main body 252-1 and each of the elastic connecting parts 25-1 to 25-4. In one example, "d1" can be the maximum spacing distance between the extension part 41A and the connecting part 60A.

[0603] In another embodiment, the spacing distance between the extension part 41A and the connecting part 60A can be equal to or greater than the spacing distance between the extension part 41A and the connecting part 60B. Or, the spacing distance between the extension part 41A and the connecting part 60A can be equal to or greater than the width of the connecting part 60B.

[0604] Figure 20a Shows Figure 18b A modified example 25-1A of the shown elastic connecting part 25-1.

[0605] In Figure 20a Among them, the reference numerals identical to those in Figure 18a And Figure 18b Represent the same components, and the descriptions made with reference to Figure 18a And Figure 18b Can be applied to the same components. Although Figure 20a Shows one elastic connecting part, its description can be equally applied to the remaining three elastic connecting parts.

[0606] Referring to Figure 20a , the elastic connecting part 25-1A can include a connecting part 60A1 and a connecting part 60B1. Compared with the elastic connecting part 25-1 shown in Figure 18b , the connecting part 60B1 of the elastic connecting part 25-1A shown in Figure 20a Can include a first connecting part 61 and a second connecting part 62, and the third connecting part 653 can be removed. The connecting part 60A1 can be provided at the intersection of the first connecting part 61 and the second connecting part 62. In one example, a hole 250a can be formed at the intersection of the first connecting part 61 and the second connecting part 62. The circuit board 250 can include Figure 18a The escape part 125A shown, andFigure 18a The description of the escape unit 125A shown can be applied to Figure 20a The escape section 125A is shown.

[0607] Figure 20b yes Figure 20a The circuit board 250 shown is a modified example 252-2 of the main body 252.

[0608] Reference Figure 20b , Figure 20b The main body 252-2 shown may include an extension 41A1 extending toward the connecting portion 60A1.

[0609] The extension 41A1 may protrude from the outer connecting surface 33-5 toward the elastic connecting portion 25-1A. In one example, the extension 41A1 may extend or protrude from the outer connecting surface 33-5 toward the connecting portion 60A1.

[0610] Figure 19b The hole shown may not be formed in one end of the extension 41A1, but the invention is not limited thereto. In another embodiment, the extension may have a groove or hole formed at one end to increase the contact area with the damper.

[0611] Reference Figure 19b The relationship between the width, d1, d2, W1, W2, and W3 of the described extension 41A1 can be applied to Figure 20b Examples of implementations.

[0612] Figure 20c It shows Figure 18b The elastic connection 25-1 shown is a modified example 25-1B.

[0613] exist Figure 20c In, with Figure 18a and Figure 18b The same reference numerals in the accompanying drawings denote the same parts, and refer to... Figure 18a and Figure 18b The description provided can be applied to the same component. Although Figure 20c One elastic connection is shown, but its description can be applied equally to the remaining three elastic connections.

[0614] exist Figure 20c In embodiment 25-1B, it is possible to obtain from Figure 18b The second connecting portion 62 is removed from the elastic connecting portion 25-1 shown. That is, the elastic connecting portion 25-1b may include a connecting portion 60A and a connecting portion 60B2, and the connecting portion 60B2 may include a first connecting portion 61 and a third connecting portion 63.

[0615] In another variation, it can be omitted. Figure 18bThe first connecting portion 62 is shown. In another variation, the elastic connecting portion may include a connecting portion 60A, a second connecting portion 62, and a third connecting portion 63.

[0616] Figure 20d It shows Figure 20c The main body 252 shown is a modified example.

[0617] Figure 20d The main body 252-1 shown may include Figure 19b The extension 41A shown can have a hole 41B formed therein. Figure 19b The description of the extension 41A and the hole 41B shown can be applied to Figure 20d The variation shown is an example of a variation.

[0618] Figure 20e A flexible connecting portion 25-1C according to another embodiment is shown.

[0619] Reference Figure 20e The elastic connection portion 25-1C may include a connecting portion 60A2 and a connecting portion 60B3. The connecting portion 60A2 is connected to each of the support members 220-1 to 220-4, and the connecting portion 60B3 extends from the body 252 and is connected to the connecting portion 60A2.

[0620] In one example, the connecting portion 60B3 may extend or protrude from a corner area of ​​the body 252. In another example, the connecting portion 60B3 may extend from the central area of ​​the corner of the body 252 toward the connecting portion 60A2.

[0621] In one example, the connector 60B3 may protrude from the outer connector surface 33-5.

[0622] In one example, the other end of each of the support members 220-1 to 220-4 connected to the connecting portion 60A2 may be located outside the connecting portion 60B3.

[0623] In one example, the width W31 of the connecting portion 60B3 can gradually decrease from one end of the connecting portion 60B3 to the other end.

[0624] One end of the connecting part 60B3 may be connected to the main body 252 of the circuit board 250, and the other end of the connecting part 60B3 may be connected to the connecting part 60A2.

[0625] Furthermore, in one example, the width of one end of the connector 60B3 can be larger than the width of the other end of the connector 60B3. The reason for setting the width of one end of the connector 60B3 to be larger than the width of the other end of the connector 60B3 is to allow the elastic connector 25-1C to be stably supported by the main body 252 of the circuit board 250, thereby increasing the elastic force of the elastic connector 25-1C in the optical axis direction and reducing the elastic force of the elastic connector 25-1C in the direction perpendicular to the optical axis, thereby stably supporting the large-diameter lens.

[0626] Figures 18a to 20b The elastic connection shown can be configured to be rotationally symmetrical about the center of the body 252 or 252-1 of the circuit board 250. In one example, the center of the body 252 or 252-1 can be the center of the opening C2 of the circuit board 250, or it can be the optical axis.

[0627] In one example Figures 18a to 20b The elastic connection shown can be rotated 90 degrees symmetrically about the center of the main body 252 or 252-1 of the circuit board 250.

[0628] Despite Figures 18a to 20e The illustrated embodiment is configured to provide a resilient connection at each corner of the body 252 or 252-1 of the circuit board 250, but the invention is not limited thereto. In another embodiment, two or more resilient connections may be provided at each corner of the body 252 or 252-1 of the circuit board 250, and Figures 18a to 20e The description of the elastic connection shown can also be applied here.

[0629] In one example, a number of resilient connections may be provided at each of the corners of the main bodies 252 and 252-1, equal to the number of support members provided at each of the corners of the shell.

[0630] In one example, the embodiment may include two support members and two resilient connections. The two support members are disposed at each of the corners of the housing 140, and the two resilient connections are disposed at each of the corners of the main body, corresponding to the support members. Each of the two resilient connections can be connected to a corresponding support member of the two support members.

[0631] Figure 21a This is a partial perspective view of the elastic connection 25-1, the main body 252 of the circuit board 250, the base 210, the first damper 310, and the second damper 310A according to the embodiment. Figure 21b It is along Figure 21a A sectional view taken along the EF direction.

[0632] Reference Figure 21a andFigure 21b The first damper 310 can be disposed between the main body 252 (e.g., escape portion 125A) of the circuit board 250 and the elastic connection portion 25-1 to interconnect the main body and the elastic connection portion.

[0633] In one example, a portion of the first damper 310 may be disposed, attached, or connected to the body 252 of the circuit board 250 (e.g., escape portion 125A), and another portion of the first damper 310 may be disposed, attached, or connected to the resilient connection portion 25-1.

[0634] In one example, another part of the first damper 310 may be set, attached, or connected to the third connection 63.

[0635] Furthermore, in one example, another portion of the first damper 310 may contact or be attached to the portion of the support member 220-1 adjacent to the hole 250a in the resilient connection portion 25-1.

[0636] Furthermore, a second damper 310A may be disposed between the elastic connection 25-1 and the corner area 212 of the base 210 to interconnect the elastic connection and the corner area of ​​the base.

[0637] The second damper 310A can be disposed between the elastic connection 25-1 and the step portion 212A of the base 210 to interconnect the elastic connection 25-1 and the step portion 212A.

[0638] In one example, the second damper 310A may be disposed between the elastic connection 25-1 and the first surface 21A of the step portion 212A of the base 210 to interconnect the elastic connection 25-1 and the first surface 21A.

[0639] In one example, the second damper 310A may be disposed on the step portion 212A of the base 210. In another example, the second damper 310A may be disposed on at least one of the first surface 21A and the second surface 21B of the step portion 212A.

[0640] Furthermore, in one example, the second damper 310A may be disposed on at least one of the third surface 21C and the fourth surface 21D of the step portion 212A.

[0641] Furthermore, the second damper 310A can be disposed on the inner surface of the corner area of ​​the cover member 300, which corresponds to or faces the corner area 212 of the base 210. Alternatively, in Figure 14In the lens moving device shown, including the base 210-1, a second damper 310A may be disposed on the inner surface of the guide portion 218 of the base 210. In this case, the second damper 310A may contact the inner surface of the guide portion 218 of the base 210.

[0642] Furthermore, at least one of the first damper 310 and the second damper 310A may be disposed in the hole 250a in the elastic connection portion 25-1. Additionally, the second damper 310A may be configured to contact the solder 902.

[0643] Although reference Figure 21a Only the elastic connection part 25-1 is described, but Figure 21a and Figure 21b The description of the first damper 310 and the second damper 310A shown can be applied to the elastic connections 25-1A, 25-1B and 25-1C according to another embodiment or variation.

[0644] Figure 22a This is a partial perspective view of the elastic connection 25-1, the main body 252-1 of the circuit board 250, the base 210-1, the first damper 310, and the second damper 310A according to the embodiment. Figure 22b It is along Figure 22a A sectional view taken along the GH direction.

[0645] Reference Figure 22a and Figure 22b The first damper 310 can be disposed between the extension 41A of the main body 252-1 of the circuit board 250 and the elastic connection 25-1.

[0646] In one example, a portion of the first damper 310 may be disposed, attached, or connected to an extension 41A of the body 252-1 of the circuit board 250, and another portion of the first damper 310 may be disposed, attached, or connected to the resilient connection 25-1.

[0647] In one example, a portion of the first damper 310 may be disposed, attached, or connected to a hole 41B in the extension 41A. The first damper 310 may be disposed, attached, or connected to a side surface of the extension 41A defined by the hole 41B.

[0648] In one example Figure 22a Another portion of the first damper 310 shown can be disposed, attached, or connected to the third connection 63. Furthermore, Figure 22a Another portion of the first damper 310 shown may contact or be attached to a portion of the support member 220-1 adjacent to the hole 250a of the elastic connection 25-1.

[0649] Figure 21a and Figure 21b The description of the second damper 310 shown can be applied to Figure 22a and Figure 22b The second damper 310 is shown. However, Figure 22a and Figure 22b The second damper 310 shown can be disposed between the extension 41A and the corner region 212 of the base 210. In one example, Figure 22a and Figure 22b The second damper 310 shown can be disposed between the extension 41A and the stepped portion 212A. Furthermore, in one example, Figure 22a and Figure 22b The second damper 310 shown may be disposed between at least one of the first surface 21A and the second surface 21B of the stepped portion 212A and the lower surface of the extension 41A.

[0650] Although reference Figure 22a Only the elastic connection part 25-1 is described, but Figure 22a and Figure 22b The description of the first damper 310 and the second damper 310A shown can be applied to the elastic connections 25-1A, 25-1B and 25-1C according to another embodiment or variation.

[0651] The first damper 310 and the second damper 310A can absorb the vibration of the OIS operating unit during OIS operation, thereby preventing the OIS operating unit from oscillating.

[0652] In one example, the first damper 310 and the second damper 310A can reduce the gain at each of the first and second resonant frequencies of the frequency response characteristics based on OIS operation, thereby preventing oscillation of the OIS operation unit.

[0653] In addition, the second damper 310A is uniformly and evenly distributed between the elastic connection 25-1 and the corner area 212 of the base 210, thereby preventing oscillations caused by OIS operation and increasing the response speed of OIS operation.

[0654] Figure 23 This is a cross-sectional view of a portion of the main body 252 and a portion of the elastic connection portion 25-1 of the circuit board 250 according to an embodiment.

[0655] The main body 252 of the circuit board 250 may include: a first conductive layer 59-1 disposed on the upper surface 21 of the base 210; and a second conductive layer 59-2 disposed on the first conductive layer 59-1.

[0656] In addition, the main body 252 may include a first insulating layer 58-1, which is disposed between the first conductive layer 59-1 and the second conductive layer 59-2, and electrically insulates the first conductive layer 59-1 and the second conductive layer 59-2 from each other.

[0657] In addition, the main body 252 may include: a second insulating layer 58-2 disposed on the second conductive layer 59-2; and a third insulating layer 58-3 disposed below the first conductive layer 59-1.

[0658] The first conductive layer 59-1 may include a first metal, and the second conductive layer 59-2 may include a second metal. In one example, the first metal and the second metal may be different from each other.

[0659] In one example, the first metal may include at least one of copper (Cu), gold (Au), silver (Ag), and nickel (Ni). In another example, the second metal may be an alloy comprising at least one of the components of the first metal, such as a copper alloy.

[0660] In another embodiment, the first metal and the second metal may be formed from the same material as each other.

[0661] Each of the first insulating layer 58-1 to the third insulating layer 58-3 may be formed of an insulating material, such as polyimide, or may be formed as a coverlay.

[0662] In one example, the elastic connection 25-1 may be part of the first conductive layer 59-1 of the body 252 that extends or protrudes from the body 252.

[0663] In one example, the elastic connection 25-1 may include a first conductive layer 59-1A, and the first conductive layer 59-1A may be part of the first conductive layer 59-1 of the body 252 that extends or protrudes from the body 252.

[0664] In one example, the resilient connection 25-1 may include a first insulating layer 58-1A disposed on the first conductive layer 59-1A. The first insulating layer 58-1A may be a portion of the first insulating layer 58-1 extending from or protruding from the body 252.
