Also, the lens driving device 100 may further include a cover member 300 .

The cover member 300 will be described.

The cover member 300 accommodates the other components 110 , 120 , 130 , 140 , 150 , 160 , 220 , 230 , and 250 in an accommodation space formed together with the base 210 .

The cover member 300 may have a box shape with an open lower portion and include a top plate and side plates, and a lower portion of the cover member 300 may be coupled to the base 210 . The top plate of the cover member 300 may have a polygonal shape, for example, a quadrangle or an octagon.

The cover member 300 may have an opening on the upper plate through which a lens (not shown) coupled to the bobbin 110 is exposed to external light. The material of the cover member 300 may be a non-magnetic material such as SUS in order to prevent sticking to the magnet 130, but it may be formed of a magnetic material and act as a yoke function to increase the electromagnetic force due to the interaction between the first coil 120 and the magnet 130.

Next, the bobbin 110 will be described.

The bobbin 110 may be equipped with a lens or lens barrel and is disposed within the housing 140 . The bobbin 110 may have a structure having an opening for mounting a lens or a lens barrel. The shape of the opening may be circular, elliptical, or polygonal, but is not limited thereto.

3 is a perspective view of the bobbin 110.

Referring to FIG. 3 , the bobbin 110 may include a plurality of side parts (eg, 110b-1 and 110b-2).

For example, the bobbin 110 may include first side portions 110b-1 corresponding to or opposite to the magnet and second side portions 110b-2 disposed between the first side portions 110b-2.

For example, the horizontal length of the side surface of the first side part 110b-2 of the bobbin 110 may be longer than the horizontal length of the side surface of the second side part 110b-2, but is not limited thereto, and both may be the same.

The bobbin 110 may include a first stopper 114 protruding in a first direction from an upper surface. The first stopper 114 of the bobbin 110 may play a role of preventing the upper surface of the bobbin 110 from directly colliding with the inner side of the upper plate of the cover member 300 even when the bobbin 110 moves in the first direction for the auto focusing function, even if the bobbin 110 moves beyond a prescribed range due to an external impact or the like.

The bobbin 110 may include at least one protrusion 25 protruding from the side surface (or outer surface) of the second side portion 110b-2. For example, the bobbin 110 may have four protrusions 25 provided on the four second side parts 110b-2, but is not limited thereto. In another embodiment, the bobbin 110 may include two protrusions disposed on the two second side parts 110b-2 facing each other.

The bobbin 110 may include a second stopper (not shown) protruding from the lower surface, and the second stopper may serve to prevent the lower surface of the bobbin 110 from directly colliding with the base 210, the second coil 230, or the circuit board 250 even if the bobbin 110 moves beyond a prescribed range due to an external impact when the bobbin 110 moves in the first direction for the auto focusing function.

The bobbin 110 may have at least one seating groove 16 for disposing or installing the first coil 120 on its side surface. For example, the seating groove 16 may be provided on the first side parts 110b-1 and the second side parts 110b-2 of the bobbin 110, but is not limited thereto.

The shape and number of the seating grooves 16 of the bobbin 110 may correspond to the shape and number of the first coils 120 disposed on the sides of the bobbin 110 .

In addition, the bobbin 110 may include a first groove 12a and a second groove 12b provided on at least one of the first and second side parts 110b-1 and 110b-2 and spaced apart from each other.

For example, the first groove 12a may be provided on any one of the two first side parts 110b-1 of the bobbin 110 facing each other, and the second groove 12b may be provided on the other of the two first side parts 110b-1 of the bobbin 110 facing each other.

The first groove 12a and the second groove 12b of the bobbin 110 may be located on or above the first coil 120 disposed on the bobbin 110, and may be connected to the mounting groove 16.

The first part extending from one end of the first coil 120 disposed on the side of the bobbin 110 may be disposed in the first groove 12a, and the second part extending from the other end of the first coil 120 disposed on the side of the bobbin 110 may be disposed in the second groove 12b.

At this time, the first part of the first coil 120 may extend to the upper surface of the bobbin 110 to be connected to the first outer frame 151 of the first upper spring 150-1, and the second part of the first coil 120 may extend to the upper surface of the bobbin 110 to be connected to the second outer frame 151 of the second upper spring 150-2.

In the embodiment, the first coil 120 extends to the upper surface of the bobbin 110 for electrical connection with the two upper springs, but is not limited thereto. In another embodiment, the above-described first and second grooves may be located below the coil 120, and the first and second portions of the coil may extend to the lower surface of the bobbin 110, and may be electrically connected to the two lower springs.

In another embodiment, the bobbin 110 may not have the mounting groove 16, and the first coil 120 may be directly wound on and fixed to side parts of the bobbin 110.

In addition, a first upper protrusion 113 coupled to the hole 151a of the first inner frame 151 of the first elastic part 150 may be provided on the upper surface of the bobbin 110 .

The bobbin 110 may have a first lower protrusion (not shown) coupled to and fixed to the hole 161a of the second elastic part 160 on its lower surface.

A thread for coupling with a lens or a lens barrel may be provided on an inner surface of the bobbin 110 . A thread may be formed on the inner surface of the bobbin 110 in a state in which the bobbin 110 is fixed by a jig or the like, and a groove 15 for fixing a jig may be provided on the upper surface of the bobbin 110. For example, the groove 15 for fixing the jig may be provided on the upper surface of the two protrusions 25 facing each other, but is not limited thereto.

Next, the first coil 120 will be described.

The first coil 120 is disposed on the outer surface of the bobbin 110 and may be a driving coil that electromagnetically interacts with the magnet 130 disposed on the housing 140 .

A driving signal (eg, a driving current or voltage) may be applied to the first coil 120 to generate electromagnetic force by interaction with the magnet 130 .

The driving signal applied to the first coil 120 may be a DC signal. For example, the driving signal may be in the form of current or voltage.

Alternatively, the driving signal applied to the first coil 120 may include a DC signal and/or an AC signal. For example, the AC signal may be a sine wave signal or a pulse signal (eg, a Pulse Width Modulation (PWM) signal).

The AF movable unit may move in a first direction, for example, an upper direction (+Z axis direction) or a lower direction (−Z axis direction) by the electromagnetic force generated by the interaction between the first coil 120 and the magnet 130. By controlling the intensity or/and polarity (e.g., the direction in which current flows) of the driving signal applied to the first coil 120 to adjust the intensity or/and direction of the electromagnetic force due to the interaction between the first coil 120 and the magnet 130, the movement of the AF movable unit in the first direction can be controlled, thereby performing the auto focusing function.

The AF movable part may include the bobbin 110 elastically supported by the first elastic part 150 and the second elastic part 160, and components mounted on the bobbin 110 and moving together with the bobbin 110. For example, the AF moving unit may include the bobbin 110 and the first coil 120 . Also, for example, the AF movable unit may further include a lens (not shown) mounted on the bobbin 110 .

The first coil 120 may be disposed on the bobbin 110 to have a closed loop shape. For example, the first coil 120 may be wound or disposed on the outer surfaces of the side parts 110b-1 and 110b-2 of the bobbin 110 so as to be wound clockwise or counterclockwise around the optical axis.

In another embodiment, the first coil 120 may be implemented in the form of a coil ring wound or disposed in a clockwise or counterclockwise direction around an axis perpendicular to the optical axis OA, and the number of coil rings may be the same as the number of magnets 130, but is not limited thereto.

The first coil 120 may be electrically connected to at least one of the first elastic part 150 and the second elastic part 160, and may be electrically connected to the circuit board 250 through the first elastic part 150 or the second elastic part 160 and the support part 220.

For example, the first coil 120 may be connected to the first inner frame 151 of the second and fourth upper springs 150-2 and 150-4 by a conductive adhesive member such as solder, and may be electrically connected to the circuit board 250 by the second and fourth support parts 220-2 and 220-4.

Next, the housing 140 will be described.

The housing 140 accommodates the bobbin 110 on the inside of which the first coil 120 is mounted or disposed.

4 is a perspective view of the housing 140, and FIG. 5 is a perspective view of the first elastic part 150, the second elastic part 150, the support part 220, the second coil 230, the circuit board 250, and the base 250.

Referring to FIGS. 4 and 5 , the housing 140 may have an opening column shape as a whole and may include a plurality of side parts forming an opening.

For example, the housing 140 may include side parts 141-1 to 141-4 spaced apart from each other and corner parts 142-1 to 142-4 spaced apart from each other.

For example, the housing 140 is located between the first side part 141-1, the second side part 141-2, the third side part 141-3, the fourth side part 141-4, the first corner part 142-1 located between the first side part 141-1 and the second side part 141-2, and between the second side part 141-2 and the third side part 141-3. It may include a second corner portion 142-2, a third corner portion 142-3 located between the third side portion 141-3 and the fourth side portion 141-4, and a fourth corner portion 142-4 located between the fourth side portion 141-4 and the first side portion 141-1.

The side parts 141-1 to 141-4 of the housing 140 may correspond to the first side parts 110b-1 of the bobbin 110, and the corner parts 142-1 to 142-4 of the housing 140 may correspond to the second side parts 110b-2 of the bobbin 110, but are not limited thereto.

Magnets 130; 130-1 to 130-4 may be disposed or installed on at least one of the side parts 141-1 to 141-4 of the housing 140, and support parts 220; 220-1 to 220-4 may be disposed on corner parts 142-1 to 142-4 of the housing 140.

The housing 140 may include mounting portions 141a provided on inner surfaces of the side parts 141-1 to 141-4 to support or accommodate the magnets 130-1 to 130-4.

The side portions 141-1 to 141-4 of the housing 140 may have grooves or holes 63 for injecting adhesive for attaching the magnets 130-1 to 130-4 to the seating portion 141a of the housing 140. For example, the hole 63 may be a through hole.

The side parts 141 - 1 to 141 - 4 of the housing 140 may be disposed parallel to the side plates of the cover member 300 . A hole 147a through which the support part 220 passes may be provided in the corner parts 142-1 to 142-4 of the housing 140.

For example, in order to easily apply the damper, the diameter of the hole 147a may gradually increase from the lower surface to the upper surface of the housing 140, but is not limited thereto, and in other embodiments, the diameter of the hole 147a may be constant.

In addition, in order to prevent direct collision with the inner surface of the cover member 300, a stopper 144 may be provided on the upper surface of the housing 140. For example, the stopper 144 may have a structure protruding upward from the upper surface of at least one of the side parts 141-1 to 141-4 of the housing 140, but is not limited thereto. In another embodiment, the stopper of the housing 140 may be disposed at at least one of the corner portions.

In addition, when the first elastic part 150 is disposed on the upper surface of the housing 140, the first elastic part 150 guides the installation position of the first outer frame 152 and prevents direct collision with the inner surface of the cover member 300. The housing 140 may have a second guide part 146 on the upper surface.

The housing 140 may include at least one second upper protrusion 143 provided on an upper surface of at least one of the corner parts 142-1 to 142-4 to be coupled with the holes 152a and 152b of the first outer frame 152 of the first elastic part 150.

The second upper protrusion 143 may be disposed on at least one of one side and the other side of the second guide part 146 of the housing 140 .

In addition, the housing 140 may include at least one second lower protrusion (not shown) provided on the lower surface of the side parts 141-1 to 142-4 or/and the corner parts 142-1 to 142-4 to be coupled to and fixed to the hole 162a of the second outer frame 162 of the second elastic part 160.

In order to secure a path through which the support part 220 passes, as well as to secure a space for filling silicon that can act as a damper, the housing 140 may have a lower portion of the corner parts 142-1 to 142-4. It may be provided with a groove 142a. For example, damping silicon may be filled in the recess 142a of the housing 140 .

The housing 140 may include a stopper 149 provided on an outer surface of at least one of the side parts 141-1 to 141-4. The stopper 149 is to prevent direct collision between the outer surface of the side parts 141-1 to 141-4 of the housing 140 and the inner surface of the side plate of the cover member 300 when the housing 140 moves in the second direction and/or the third direction.

In order to prevent the bottom surface of the housing 140 from colliding with the base 210, the second coil 230, and/or the circuit board 250 to be described later, the housing 140 may further include a stopper (not shown) protruding from the lower surface.

The housing 140 may include grooves 145 provided on inner surfaces of the corner portions 142-1 to 142-4 to correspond to the protruding portion 25 of the bobbin 110.

Next, the magnet 130 will be described.

In the initial position of the bobbin 110, the magnet 130 overlaps the first coil 120 in at least a portion in a direction perpendicular to the optical axis OA or in a second direction or a third direction. For example, the magnet 130 may be inserted or disposed in the seating portion 141a of the housing 140 .

Here, the initial position of the bobbin 110 is the initial position of the AF movable part (e.g., bobbin) in a state where power or a driving signal is not applied to the first coil 120, and the first elastic part 150 and the second elastic part 160 may be a position where the AF movable part is placed as it is elastically deformed only by the weight of the AF movable part.

In addition, the initial position of the bobbin 110 is when gravity acts in the direction from the bobbin 110 to the base 210, or, conversely, when gravity acts in the direction from the base 210 to the bobbin 110, the AF movable part may be placed.

In another embodiment, the magnet 130 may be disposed on the outer surface of the side parts 141-1 to 141-4 of the housing 140. Alternatively, in another embodiment, the magnet 130 may be disposed on the inner or outer surfaces of the corner portions 142-1 to 142-4 of the housing 140.

The shape of the magnet 130 may be a rectangular parallelepiped shape corresponding to the side parts 141-1 to 141-4 of the housing 140, but is not limited thereto, and the surface facing the first coil 120 may be formed to correspond to or match the curvature of the corresponding surface of the first coil 120.

The magnet 130 may be a unipolar magnetized magnet arranged such that a first surface facing the first coil 120 has an N pole and a second surface opposite to the first surface has an S pole. However, it is not limited thereto, and it is also possible to configure the polarity reversely. Alternatively, in another embodiment, each of the first and second surfaces of the magnet 130 may be divided into an N pole and an S pole.

Alternatively, in another embodiment, the magnet 130 may be an anode magnetized magnet divided into two in a direction perpendicular to the optical axis. In this case, the magnet 130 may be implemented with ferrite, alnico, or rare earth magnet.

For example, the magnet 130 may include a first magnet part, a second magnet part, and a non-magnetic barrier rib. The first magnet part and the second magnet part may be spaced apart from each other, and the non-magnetic barrier rib may be positioned between the first magnet part and the second magnet part.

The non-magnetic barrier rib is a portion that is substantially non-magnetic and may include a section having little polarity, and may be filled with air or made of a non-magnetic material.

In the embodiment, the number of magnets 130 is four, but is not limited thereto, and the number of magnets 130 may be at least two, and the first surface of the magnet 130 facing the first coil 120 may be a plane, but is not limited thereto and may be a curved surface.

At least two or more magnets 130 may be disposed on side surfaces of the housing 140 facing each other, and may be disposed facing each other.

A plane of each of the magnets 130-1 to 130-4 may have a substantially quadrangular shape, or may have a triangular or rhombus shape.

In another embodiment, the housing 140 may be omitted, and the magnets 130-1 to 130-4 may be disposed on the cover member 300. In another embodiment, the housing 140 may not be omitted, and the magnets 130-1 to 130-4 may be disposed on the cover member 300.

Alternatively, in another embodiment, the magnets 130-1 to 130-4 may be disposed on inner surfaces of the side plates of the cover member 300.

Next, the first elastic part 150, the second elastic part 160, and the support part 220 will be described.

The first elastic part 150 and the second elastic part 160 are coupled to the bobbin 110 and the housing 140 and support the bobbin 110 .

As described above, the housing 140 may move in the second and/or third directions due to the interaction between the magnet 130 and the second coil 230 corresponding to each other, and thus hand shake correction may be performed.

The position sensor 240 may detect the strength of the magnetic field of the magnet 130 disposed on the housing 140 as the housing 140 moves in a direction perpendicular to the optical axis, and output signals (e.g., output voltage) according to the detected result.

Referring to FIG. 7 , the circuit board 250 may include a plurality of pad parts 41 to 44 disposed on an upper surface thereof. Here, in the pad parts 41 to 44 of the circuit board 250, the term pad part may be used instead of the term “bonding part, electrode part, lead part, or terminal part”.

For example, each of the plurality of pad parts 41 to 44 may be positioned adjacent to a corresponding one of the holes 250a of the circuit board 250 .

Each of the plurality of pad parts 41 to 44 may be located lower than the upper surface of the circuit board 250 . For example, a step d1 may exist between the upper surfaces of the plurality of pad parts 41 to 44 and the upper surface of the circuit board 250 in the optical axis direction. For example, the step d1 may be 35 mm to 40 mm. For example, the step d1 may be 37.5 mm.

The circuit board 250 may include an exposure area 14a exposing the plurality of pad parts 41 to 44 . An upper surface of the exposure region 14a may be positioned on the same plane as an upper surface of the pad portion (eg, 41 ) exposed by the exposure region 14a.

For example, the upper surface of the exposed region 14a may be positioned lower than the upper surface of the circuit board 250, and a step may exist between the upper surface of the exposed region 14a and the upper surface of the circuit board 250 in the optical axis direction.

The exposed area 14a of the circuit board 250 may contact the grooves 71a to 71d of the circuit board 250, and may be exposed or open to the side of the circuit board 250 or the grooves 71a to 71d. Since the exposed region 14a may be exposed or opened to the side of the circuit board 250, solder may well permeate into the pad portions 41 to 44 of the circuit board 250 through the exposed region 14a during soldering, so that solderability may be improved.

The circuit board 250 may include a plurality of grooves 71a to 71d provided on a side surface.

The grooves 71a to 71d have the form of a via hole or a groove in which the side of the circuit board 250 is open, but is not limited thereto, and may have a through hole or through via form in another embodiment.

Referring to FIG. 9 , the circuit member 231 may include a plurality of pad parts 35a to 35d disposed on a lower surface corresponding to the plurality of pad parts 41 to 44 of the circuit board 250 . In the pad parts 35a to 35 of the circuit member 231, the term pad part may be used instead of the term “bonding part, electrode part, lead part, or terminal part”.

Each of the pad parts 35a to 35d of the circuit member 231 may contact or be adjacent to a corresponding one of the escape grooves 230a of the circuit member 231 .

Each of the pad parts 35a to 35d of the circuit member 231 may be positioned higher than a lower surface of the circuit member 231 . For example, a step d2 may exist between the lower surfaces of the plurality of pad parts 35a to 35d and the lower surface of the circuit member 231 in the optical axis direction. For example, the level difference d2 may be 35 mm to 40 mm. For example, the step d2 may be 37.5 mm.

A portion of each of the pad parts 35a to 35d of the circuit member may overlap a corresponding one of the plurality of pad parts 41 to 44 in the optical axis direction. Other portions of the pad portions 41 to 44 of the circuit board 250 that do not overlap with the pad portions 35a to 35d of the circuit member 231 in the optical axis direction may be exposed from the circuit member 231 by the escape groove 230a. This is to couple the pad parts 41 to 44 and the pad parts 35a to 35d through soldering.

Between the pad portions 41 to 44 of the circuit board 250 and the pad portions 35a to 35d of the circuit member 231 due to the step d1 between the upper surface of the pad portions 41 to 44 of the circuit board 250 and the upper surface of the circuit board 250 and the step d2 between the pad portions 35a to 35d of the circuit member 231 and the lower surface of the circuit member 231. Separation distance or space size may increase.

Therefore, when soldering the pad parts 41 to 44 of the circuit board 250 and the pad parts 35a to 35d of the circuit member 231, the solder can penetrate well between the pad parts 41 to 44 of the circuit board 250 and the pad parts 35a to 35d of the circuit member 231, and the solderability can be improved.

For example, the second surface 26b of the stepped portion 26 has a second step T2 with the lower surface of the base 210 in the direction from the lower surface 21a to the upper surface 21b of the base 210, and may be parallel to the lower surface 26a of the base 210.

For example, the second step T2 may be smaller than the first step T1 (T2 < T1), and the second surface 26b of the stepped portion 26 may be positioned between the first surface 26a and the lower surface 26a of the base 210.

The base 210 may have a hole 22a disposed or positioned on the second surface 26b of the stepped portion 26 . The hole 22a may pass through the upper surface 21b of the base 210 and the second surface 26b of the stepped portion 26, and some of the terminals 81a to 81d may be exposed or opened from the upper surface 21b of the base 210 through the hole 22a.

Next, the terminals 81a to 81d will be described.

The terminals 81a to 81d are disposed or mounted on the lower, lower, or lower surface of the base 210. The number of terminals may match the number of supports, but is not limited thereto. Terminals The terminals 81a to 81d may be expressed as terminal members or terminal units.

For example, the embodiment may include first to fourth terminals 81a to 81d corresponding to the first to fourth supporters 220-1 to 220-4.

For example, the first to fourth terminals 81a to 81d may be disposed at four corners or four corner portions of the base 210 .

11 is a perspective view of the first terminal 81a and the first support part 220-1.

The description of the first terminal 81a described in FIG. 11 may be equally applied to the remaining second to third terminals.

Referring to FIG. 11 , the first terminal 81a may include a first coupling portion 310 and a second coupling portion 320 . The first coupler 310 may be referred to as a “first connector” or a “first part”, and the second coupler 320 may be referred to as a “second connector” or a “second part”.

The second coupling portion 320 may be disposed between the base 210 and the circuit board 250 , and the first coupling portion 310 may be disposed lower than the second coupling portion 320 .

For example, the second coupling part 320 may be positioned at the same height as or lower than the upper surface of the base 210 .

The upper surface of the second coupling part 320 may be exposed to the upper surface of the base 210 and the lower surface of the first coupling part 310 may be exposed to the lower surface of the base 210 .

The area of the first coupler 310 (eg, the area of the upper surface) may be greater than the area of the second coupler 320 (eg, the area of the top surface).

For example, the length of the first coupling portion 310 in the direction from the first corner portion 91a to the second corner portion 91b of the base 210 may be longer than the length of the second coupling portion in the direction from the first corner portion 91a to the second corner portion 91b.

The first coupling part 310 may be located below the lower surface of the base 210 and may be located above the first holder 600 and the second holder 800 of the camera module 200 (see FIG. 18).

The first terminal 81a may include a connection portion 315 connecting the first coupling portion 310 and the second coupling portion 320 . The connection part 315 may also be expressed as a "third connector" or a "third part".

The connecting portion 315 may have a bent form that is bent or bent from the first coupling portion 310 . The connection part 315 may be integrally formed with the first coupling part 310 and the second coupling part 320, but is not limited thereto. In another embodiment, the connection part may be assembled to the base 210 as a separate configuration from the first coupling part 310 and the second coupling part 320, and may be disposed on the side of the base 210.

The first coupling part 310 may include a hole 305 through which the support part (eg, 220-1) passes and a hole 311 coupled to the protrusion 28 of the stepped part 26 of the base 210.

The hole 305 of the first coupling part 310 may be a through hole. The hole 305 of the first coupler 310 may correspond to the hole 210a of the base 210, and may overlap with the hole 210a of the base 210 in the direction of the optical axis or from the lower surface 21a to the upper surface 21b of the base 210.

One end of the support part (eg, 220-1) may be coupled to the first coupling part 510 of the first outer frame 151 of the upper spring (eg, 150-1).

In addition, the other end of the support part (eg, 220-1) may pass through the hole 305 of the terminal (eg, 81a) and be coupled to the lower surface of the first coupling part 310 by solder 902 (see FIG. 14).

For example, the lens driving device 100 may further include solder 902 for coupling the other end of the support part (eg, 220-1) passing through the hole 305 and the lower surface of the first coupler 310 to each other.

The hole 311 of the first coupling portion 310 is coupled to the protrusion 28 of the base 210 to improve the coupling force between the base 210 and the terminals 81a to 81d, as well as to improve the solderability between the first coupling portion 310 and the support.

As the area of the first coupling portion 310 increases, heat is well conducted to the periphery of the first coupling portion 310 during soldering, so soldering between the support portion (e.g., 220-1) and the hole 305 of the first coupling portion 310 may not work well. The hole 311 of the first coupling portion 310 may suppress conduction of heat during soldering, thereby improving solderability between the support portion (eg, 220-1) and the hole 305 of the first coupling portion 310.

The first coupling part 310 may be disposed or positioned below the first surface 26a of the stepped part 26 of the base 210 .

The second coupling portion 320 is connected to one end of the first coupling portion 310 and may be disposed or located below the second surface of the stepped portion 26 of the base 210 .

A part 321 of the second coupling part 320 may be exposed to the upper surface 21b of the base 210 through the hole 22a of the stepped part 26 . Hereinafter, a portion 321 of the second coupling portion 320 is referred to as an exposed area 321 of the second coupling portion 320 .

In addition, the first terminal 81a may further include an extension portion 330 extending from the other end of the first coupling portion 310 .

The extension part 330 may be parallel to the first coupling part 310, may be located on the same plane, and may be inserted into the base 210.

The extension part 330 may improve coupling force between the first terminal 81a and the base 210 .

For example, the first coupling portion 310, the second coupling portion 320, and the extension portion 330 may be integrally formed. For example, it is possible to have a structure in which the terminals 81a to 81d are inserted into the base 210 by using an insert injection method.

For example, the terminals 81a to 81d may be insert-injected into the base 210, and at least a portion of each of the first coupling part 310 and the second coupling part 320 may be inserted or disposed in the base 210.

Also, for example, the terminals 81a to 81d may be insert-injected with the base 210, and the connection part 315 may be disposed within the base.

In another embodiment, the terminal may be attached to or coupled to the lower or upper surface of the base 210 instead of being insert-injected with the base.

12 is a part of a perspective view in which the base 210, the first terminal 81a, and the circuit board 250 are coupled to each other, FIG. 13 shows a bottom view of the circuit board 250, FIG. 14 shows solder 902 for showing the connection between the terminals 81a to 81d and the support parts 220-1 to 220-4, and FIG. 15 shows the pad part of the circuit board 250. 257, and FIG. 16 is a cross-sectional view in the AB direction of the lens driving device 100 shown in FIG.

12 to 16 , a circuit board 250 may be disposed on the upper surface of the base 210, and each of the grooves 71a to 71d of the circuit board 250 may expose a corresponding one of the second coupling parts 320 of the terminals 81a to 81d exposed from the upper surface 21b of the base 210.

In addition, as shown in FIGS. 6 and 7 , each of the grooves 230a of the circuit member 231 may expose a corresponding upper surface of any one of the second coupling parts 320 of the terminals 81a to 81d exposed to the upper surface of the base 210.

The circuit board 250 may include pad portions 257 disposed on upper and lower portions and on side surfaces between the upper and lower portions.

The number of pad parts 257 may be plural, and may be disposed corresponding to the terminals 81a to 81d or disposed at positions corresponding to the terminals 81a to 81d. For example, the four pad parts 247 corresponding to the terminals 81a to 81d may be disposed at four corners or corner parts of the circuit board 250, but are not limited thereto.

In another embodiment, the pad part may be disposed only at two corners or corner portions of the circuit board 250, and may be electrically connected to the two terminals 251 of the circuit board 250 to provide a driving signal to the first coil. For example, the two corners where the pad part is disposed may be corners in a diagonal direction of the circuit board or two corners in contact with one side.

In another embodiment, four pad parts may be disposed at four corners or corner parts of the circuit board 250, the pad parts disposed at the two corners may be soldered to terminals (eg, 81a, 81b), and may be electrically connected to the two terminals 251 of the circuit board 250, but the pad parts disposed at the other two corners may be soldered to terminals (eg, 81a, 81b). However, it may not be electrically connected to the terminals 251 of the circuit board 250 . This is to prevent problems such as mechanical tilt of the lens driving device by soldering all terminals of the four pad parts.

The pad part 257 may be an Au plating layer or a copper plating layer containing Au.

For example, the pad part 257 may be provided in each of the grooves 71a to 71d of the circuit board 250 . Although FIG. 12 shows only the pad part 257 provided in the groove 71a, the description of the pad part 257 of FIG. 12 can be equally applied to the pad parts provided in the other grooves 71b to 71d.

The pad part 257 of the circuit board 257 may be disposed on a top surface of the circuit board 250 , a bottom surface of the circuit board 250 , and a side surface connecting the top surface and bottom surface of the circuit board 250 .

For example, the pad part 257 may be disposed on a side surface of the groove (eg, 71a), an upper surface of the circuit board 250 contacting the side surface of the groove (eg, 71a), and a lower surface of the circuit board 250 contacting the side surface of the groove (eg, 71a).

For example, the pad part 257 of the circuit board 250 includes a first pad 259b disposed below the circuit board 250 contacting the side surface of the groove 71a, a second pad 259a disposed above the circuit board 250 contacting the side surface of the groove 71a, and a third pad disposed on the side surface of the groove 71a and connecting the first pad 259b and the second pad 259a ( 605) may be included.

The third pad 605 may be disposed on a side surface of the circuit board 250 .

Vias or grooves may be provided on side surfaces of the grooves 71a to 71d of the circuit board 250, and a part of the pad unit 257 (eg, the third pad 605) may be disposed in the via or groove.

The third pad 605 of the pad part 257 of the circuit board 250 may have a curved shape depressed from a side surface of the groove 71a, for example, a semicircular via shape.

For example, the via may have a radius of 0.1 mm to 0.5 mm, but is not limited thereto. For example, the via may have a radius of 0.2 mm to 0.3 mm. For example, the radius of the via may be 0.2 mm.

When the radius of the via is less than 0.1 mm, the adhesion and solderability between the pad portion 257 of the circuit board 250 and the terminal may be insignificantly improved, and when the radius of the via is greater than 0.5 mm, the pad portion 257 is larger than necessary for soldering compared to the second coupling portion 320 of the terminals 81a to 81d. Therefore, cost may increase and the degree of freedom of the pattern of the circuit board 250 decreases. It can be.

The first pad 259b of the pad part 257 of the circuit board 250 may face the terminal (eg, 81a) in the optical axis direction.

The first pad 259b of the pad portion 257 of the circuit board 250 may contact the exposed region 321 of the second coupling portion 320 of the first terminal 81a.

Referring to FIG. 15 , the circuit board 250 includes a first insulating layer 601, a first conductive layer 602a disposed on the upper surface of the first insulating layer 601, a second insulating layer 603a disposed on the upper surface of the first conductive layer 602a, a second conductive layer 602b disposed on the lower surface of the first insulating layer 601, and a third insulating layer disposed on the lower surface of the second conductive layer 602b. A layer 603a may be included.

Also, for example, a first adhesive layer may be disposed between the first insulating layer 601 and the first conductive layer 602a, and a second adhesive layer may be disposed between the third insulating layer 603a and the second conductive layer 602b.

The first conductive layer 602a may be a patterned metal layer, for example, a Cu plating layer.

The second conductive layer 602b may be a metal layer (eg, a Cu layer) or a patterned metal layer.

For example, the first conductive layer 602a may be patterned to include wires and pads electrically connected to the support parts 220-1 to 220-4, the second coil 230, and the second position sensor 240.

The first to third insulating layers 601, 603a, and 603b may be resin, for example, polyimide, but are not limited thereto.

The first pad 259b may be disposed on the lower surface of the second conductive layer 602b, and the second pad 259a may be disposed on the upper surface of the first conductive layer 602a.

For example, the lower surface of the first pad 259b may be positioned higher than the lower surface of the third insulating layer 603b of the circuit board 250 .

For example, the second pad 259a of the pad unit 257 may be electrically connected to a corresponding one of the terminals 251 of the circuit board 250 by the patterned first conductive layer 602a.

The upper surface of the first conductive layer 602a may include a region 59a exposed from the second insulating layer 603a for contact with the second pad 259a, and the lower surface of the second conductive layer 602b may include a region 59b exposed from the third insulating layer 603b for contact with the first pad 259b.

For example, the first pad 259b may be disposed on the exposed region 59b of the lower surface of the second conductive layer 602b, and the second pad 259a may be disposed on the exposed region 59a of the upper surface of the first conductive layer 602a.

For example, the area of the first pad 259b contacting the exposed region 59b on the lower surface of the second conductive layer 602b may be larger than the area of the second pad 259a contacting the exposed region 59a on the upper surface of the first conductive layer 602a.

The exposed region 14a of the circuit board 250 may be a portion of the patterned first conductive layer 602a exposed by the second insulating layer 603a, and the upper surface of the exposed region 14a may be the upper surface of the patterned first conductive layer 602a.

The pad parts 41 to 44 and the pad part 257 of the circuit board 250 may be spaced apart from each other, electrically separated from each other, and positioned within the exposed region 14a.

For example, a step may exist between the lower surface of the first pad 259 b of the circuit board 250 and the lower surface of the third insulating layer 603 b or between the lower surface of the first pad 259 b and the exposed region 321 of the second coupling part 320 in the direction from the lower surface of the circuit board 250 to the upper surface, and the step difference may be 25.5 mm to 27.5 mm.

The third pad 605 of the pad part 257 may be disposed on the side surface of the first insulating layer 601, connect the second pad 259a and the first pad 259b of the pad part 257, and may be a plating layer. For example, each of the first pad 259b, the second pad 259a, and the third pad 605 of the pad unit 257 may have a thickness of 10 mm to 12 mm.

For example, the third pad 605 of the pad part 257 may be a gold (Au) plating layer, but is not limited thereto.

The exposed region 321 of the second coupling portion 320 of the terminals 81a to 81d and the pad portion 257 of the circuit board 257 may be coupled by a conductive adhesive member or solder, and both may be electrically connected.

An area of the first pad 259b of the pad portion 257 of the circuit board 250 may be larger than that of the second pad 259a, but is not limited thereto.

16, the ratio (H3/H1) of the first distance H3 to the second distance H1 may be 1.18 to 1.2, and the ratio (H3/H) of the first distance H3 to the third distance H may be 1.16 to 1.17. For example, the ratio (H3/H) may be 1.1667 and the ratio (H3/H1) may be 1.188.

The first distance H3 may be a distance from the lower surfaces of the upper springs 150-1 to 150-4 to the lower surfaces of the first coupling portions 310 of the terminals 81a to 81d. The second distance H1 may be a distance from the lower surface of the upper springs 150-1 to 150-4 to the lower surface of the circuit member 231. The third distance H may be a distance from the lower surface of the upper springs 150-1 to 150-4 to the lower surface of the circuit board 250.

As the thickness of the mobile phone becomes thinner, the height of the camera module decreases, and as the height of the camera module decreases, the length of the OIS wire (e.g., the above-mentioned support portions 220-1 to 220-4) of the lens driving device becomes shorter, and current consumption may increase due to the decrease in the length of the OIS wire. If the diameter of the OIS wire is reduced to prevent such an increase in current consumption and deterioration in reliability, there is a risk that the OIS wire is disconnected and the reliability of the OIS drive may be deteriorated. .

In the embodiment, the length of the support parts 220-1 to 220-4 can be increased by coupling the support parts 220-1 to 220-4 to the lower surfaces of the terminals 81a to 81d located below the circuit board 250, thereby reducing the intensity of the current flowing through the support parts 220-1 to 220-4, thereby reducing power consumption, and the support parts 220-1 to 220-4 ) can be prevented from deteriorating the reliability of OIS driving due to the reduction in diameter.

When the ratio (H3/H1) is less than 1.18 or the ratio (H3/H) is less than 1.16, the increase in the length of the support parts 220-1 to 220-4 is insignificant, so that the effect of reducing power consumption cannot be obtained, and the reliability of the OIS drive due to the decrease in the diameter of the support parts 220-1 to 220-4 cannot be prevented.

Also, when the ratio (H3/H1) exceeds 1.2 or the ratio (H3/H) exceeds 1.17, the thickness of the lens driving device may increase.

For example, the distance H2 from the lower surface of the upper springs 150-1 to 150-4 to the upper surface of the circuit member 231 may be 1.86 mm.

For example, the height (or thickness in the optical axis direction) of the housing 140 may be 1.3 mm to 2 mm. For example, the height (or thickness in the optical axis direction) of the housing 140 may be 1.4 mm to 1.6 mm. For example, the height (or thickness in the optical axis direction) of the housing 140 may be 1.51 mm.

FIG. 17A shows the connection between the circuit board 25a and the terminal 8a by solder 86, and FIG. 17B shows the connection between the pad part 257 of the circuit board 250 and the terminal 81a according to the embodiment.

Referring to FIG. 17A , the circuit board 25a may include a pad part 58 disposed only on the lower surface. When the pad portion 58 is disposed only on the lower surface of the circuit board 25a, the space between the lower surface of the circuit board 25a and the terminal 8a is narrow, so that solder does not permeate well between the circuit board 25a and the terminal 8a during soldering, resulting in poor solderability, which may cause electrical disconnection between the terminal 8a and the circuit board 250.

Referring to FIG. 17B , the lens driving device 100 according to the embodiment may include a conductive adhesive member or solder 410 coupling the terminals 81a to 81d and the pad part 257 of the circuit board 250.

The solder 410 may be disposed between the second coupling portion 320 (eg, the exposed region 321 ) and the first pad 259b of the pad portion 257 of the circuit board 250 . Also, the solder 410 may be further disposed on the second pad 259a and the third pad 605 .

For example, the solder 410 may be disposed between the first to third pads 259b, 259a, and 605 of the circuit board 250 and the second coupling part 320 (eg, the exposed area 321).

Since the pad unit 257 according to the embodiment includes a first pad 259b disposed under the circuit board 250, a third pad 605 provided on the side surface of the grooves 71a to 71d of the circuit board 250, and a second pad 259a disposed above the circuit board 250, solder is applied to the third pad 605 and the second pad 259 of the circuit board 250 during soldering. a), and as a result, the surface tension of the solder increases, so that the penetration of the solder between the first pad 259b of the circuit board 250 and the exposed regions 231 of the terminals 81a to 81d can increase. As a result, solderability and bonding force between the pad portion 257 of the circuit board 250 and the terminals 81a to 81d can be improved, and thus electrical disconnection between the terminals and the circuit board can be prevented.

In addition, since the third pad 605 of the circuit board 250 has a curved shape, a contact area may be increased, and thus solderability between the pad portion 257 of the circuit board 250 and the terminals 81a to 81d may be improved, and bonding strength may be improved.

The embodiments shown in FIGS. 1 to 17 do not include an AF position sensor for driving AF feedback, but are not limited thereto. In another embodiment, an AF position sensor for driving AF feedback may be further included. In this case, the AF position sensor may be located on the bobbin 110.
