The first driving unit 500 may move the lens module 200 to focus on a subject. For example, the first driver 500 may generate a driving force in the direction of an optical axis (Z-axis) to move the carrier 400 . Since the lens module 200 is disposed in the carrier 400 , the carrier 400 and the lens module 200 may be moved together in the direction of the optical axis (Z-axis) by the driving force of the first driving unit 500 .

The first driving unit 500 includes a first magnet 510 and a first coil 530 . The first magnet 510 and the first coil 530 may be disposed to face each other in a direction perpendicular to the optical axis (Z-axis).

The first magnet 510 is mounted on the carrier 400 . For example, the first magnet 510 may be mounted on one side of the carrier 400 .

One surface of the first magnet 510 (eg, a surface facing the first coil 530) may be magnetized to have both an N pole and an S pole. For example, an N pole, a neutral region, and an S pole may be sequentially provided on one surface of the first magnet 510 facing the first coil 530 along the optical axis (Z-axis) direction.

The other surface (eg, the opposite surface of one surface) of the first magnet 510 may be magnetized to have both an S pole and an N pole. For example, an S pole, a neutral region, and an N pole may be sequentially provided on the other surface of the first magnet 510 along the optical axis (Z-axis) direction.

The first coil 530 is disposed to face the first magnet 510 . For example, the first coil 530 may be disposed to face the first magnet 510 in a direction perpendicular to the optical axis (Z-axis).

A first ball member B1 is disposed between the carrier 400 and the housing 110 . For example, the first ball member B1 may be disposed between the carrier 400 and the housing 110 to reduce friction when the carrier 400 moves.

The first ball member B1 includes a plurality of balls disposed along the optical axis (Z-axis) direction. The plurality of balls may roll in the direction of the optical axis (Z-axis) when the carrier 400 moves in the direction of the optical axis (Z-axis).

A first yoke 570 is disposed in the housing 110 . The first yoke 570 may be disposed at a position facing the first magnet 510 . For example, the first coil 530 may be disposed on one surface of the substrate 750 and the first yoke 570 may be disposed on the other surface of the substrate 750 .

The first magnet 510 and the first yoke 570 may generate an attractive force between them. For example, the first yoke 570 may be made of a magnetic material. An attractive force acts between the first magnet 510 and the first yoke 570 in a direction perpendicular to the optical axis (Z-axis).

The first ball member B1 may come into contact with the carrier 400 and the housing 110 by the attractive force of the first magnet 510 and the first yoke 570 .

Guide grooves may be disposed on surfaces where the carrier 400 and the housing 110 face each other. For example, the carrier 400 may have a first guide groove 410 and the housing 110 may have a second guide groove 120 .

The first guide groove 410 and the second guide groove 120 each extend in the direction of the optical axis (Z-axis). The first ball member (B1) is disposed between the first guide groove 410 and the second guide groove 120.

Some of the plurality of balls of the member B1 (eg, a first ball group BG1 to be described later) are disposed.

Among the plurality of balls included in the first ball group BG1, the outermost balls in a direction parallel to the optical axis (Z-axis) are in two-point contact with the first groove g1 and the third groove g3, respectively. can

That is, among the plurality of balls included in the first ball group BG1, the outermost balls in a direction parallel to the optical axis (Z-axis) each have two points of contact with the first groove g1 and a third groove g3 can be in two-point contact with

The first ball group BG1 , the first groove g1 , and the third groove g3 may function as main guides for guiding movement of the carrier 400 in the optical axis (Z-axis) direction.

The second groove g2 and the fourth groove g4 are disposed to face each other in a direction perpendicular to the optical axis (Z-axis) direction, and the first ball is disposed in the space between the second groove g2 and the fourth groove g4. Some of the plurality of balls of the member B1 (eg, a second ball group BG2 described later) are disposed.

Among the plurality of balls included in the second ball group BG2, the outermost balls in a direction parallel to the optical axis (Z-axis) are in two-point contact with any one of the second groove g2 and the fourth groove g4. and can make one-point contact with the other.

For example, among the plurality of balls included in the second ball group BG2, the outermost balls in a direction parallel to the optical axis (Z-axis) are in contact with the second groove g2 at one point, and the fourth groove g4 can be in two-point contact with (and vice versa).

The second ball group BG2 , the second groove g2 , and the fourth groove g4 may function as auxiliary guides supporting movement of the carrier 400 in the optical axis (Z-axis) direction.

The first ball member B1 includes a first ball group BG1 and a second ball group BG2, and the first ball group BG1 and the second ball group BG2 are each in the optical axis (Z-axis) direction. It includes a plurality of balls arranged along.

The first ball group BG1 and the second ball group BG2 are spaced apart from each other in a direction perpendicular to the optical axis (Z-axis) (eg, X-axis direction). The number of balls in the first ball group BG1 and the number of balls in the second ball group BG2 may be different (see FIG. 6).

For example, the first ball group BG1 includes three or more balls disposed along the optical axis (Z-axis) direction, and the second ball group BG2 has a greater number of balls included in the first ball group BG1. Contains fewer balls.

The number of balls belonging to each ball member may be changed under the premise that the number of balls belonging to the first ball group BG1 and the number of balls belonging to the second ball group BG2 are different. Hereinafter, for convenience of description, an embodiment in which the first ball group BG1 includes three balls and the second ball group BG2 includes two balls will be described.

Among the three balls included in the first ball group (BG1), the two balls disposed on the outermost side in a direction parallel to the optical axis (Z-axis) have the same diameter as each other, and one ball disposed between them is on the outermost side. It may be smaller in diameter than the balls placed.

For example, among the plurality of balls included in the first ball group BG1, two balls disposed at the outermost side in a direction parallel to the optical axis (Z-axis) have a first diameter, and one ball disposed between them has a first diameter. It has 2 diameters, the first diameter being larger than the second diameter.

The two balls included in the second ball group BG2 may have the same diameter. For example, two balls included in the second ball group BG2 have a third diameter.

Also, the first diameter and the third diameter may be the same. Here, the fact that the diameters are the same may mean not only physically the same case, but also include errors in manufacturing.

Among the plurality of balls included in the first ball group (BG1), the distance between the centers of the outermost balls in a direction parallel to the optical axis (Z-axis) and the plurality of balls included in the second ball group (BG2) The distances between the centers of the outermost balls in a direction parallel to the optical axis (Z-axis) are different.

For example, the distance between the centers of the two balls having the first diameter is greater than the distance between the centers of the two balls having the third diameter.

When the carrier 400 moves in the direction of the optical axis (Z-axis), in order to move in parallel to the direction of the optical axis (Z-axis) (that is, to prevent tilt from occurring), the first magnet 510 and the second 1 The center point CP of the force acting between the yokes 570 should be located within the support area A connecting the contact points of the first ball member B1 and the carrier 400 or the housing 110. do.

When the action center point CP of the attraction moves out of the support area A, the position of the carrier 400 is distorted during the movement of the carrier 400, so there is a concern that a tilt may occur. Therefore, it is necessary to form the support area A as wide as possible.

One embodiment of the present invention intentionally forms a size (eg, diameter) of some of the plurality of balls of the first ball member (B1) smaller than the size (eg, diameter) of the other balls. In this case, large-sized balls among a plurality of balls may be intentionally brought into contact with the carrier 400 or the housing 110 .

Referring to FIG. 6, since the diameters of two of the three balls of the first ball group BG1 are greater than the diameter of the other ball, the two balls of the first ball group BG1 are respectively carrier 400. ) and contact with the housing 110. Also, since the two balls of the second ball group BG2 have the same diameter, the two balls of the second ball group BG2 contact the carrier 400 and the housing 110, respectively.

Therefore, as shown in FIG. 6, when viewed from the direction of the second axis (Y-axis), the first ball member B1 is in contact with the carrier 400 or the housing 110 at four points. Also, the support area A connecting the contact points to each other may have a quadrangular shape (eg, trapezoidal shape).

Therefore, the support area A can be formed relatively wide, and thus, the center point CP of the attractive force acting between the first magnet 510 and the first yoke 570 can be stably established. ) can be placed within. Therefore, driving stability during focus adjustment can be ensured.

Meanwhile, even if the two balls of the second ball group BG2 are manufactured to have the same diameter, the two balls of the second ball group BG2 may not physically have exactly the same diameter due to errors in manufacturing. In this case, any one of the two balls of the second ball group BG2 may contact the carrier 400 or the housing 110.

Accordingly, the support area A connecting the contact points where the first ball member B1 contacts the carrier 400 or the housing 110 may have a triangular shape.

Even if the support area (A) has a triangular shape, since the support area (A) can be formed widely by the outermost balls in a direction parallel to the optical axis (Z-axis) among the three balls of the first ball group (BG1), the focal point Driving stability during adjustment can be ensured.

Apart from ensuring driving stability during focus adjustment, reducing the height in the direction of the optical axis (Z-axis) of the camera module 1 (i.e. slimming) is also an important issue. When the height in the Z-axis direction is reduced, the height of the support area A in the optical axis (Z-axis) direction may also be reduced.

Therefore, when simply reducing the height of the camera module 1 in the optical axis (Z-axis) direction, there is a concern that a problem may occur in driving stability during focus adjustment.

Accordingly, in the camera module 1 according to an embodiment of the present invention, the third and fourth grooves g3 and g4 may have different lengths in the optical axis (Z-axis) direction. For example, the length of the third groove g3 in the optical axis (Z-axis) direction may be longer than the length of the fourth groove g4 in the optical axis (Z-axis) direction.

And, by locating the action center point (CP) of the force acting between the first magnet 510 and the first yoke 570 closer to the third groove, which is the main guide, the height of the camera module 1 in the optical axis direction is increased. Even if it is reduced, it is possible to stably position the action center point (CP) of attraction within the support area (A).

In one embodiment of the present invention, the number of balls belonging to the first ball group BG1 and the number of balls belonging to the second ball group BG2 are configured differently, while the space in which each ball group is accommodated By forming different lengths in the direction of the optical axis (Z-axis), the size of the support area (A) is prevented from being changed, or even if the size of the support area (A) is changed, the center point (CP) of the action of attraction is the support area (A) can be avoided.

In addition, among the main guide and the auxiliary guide, the size of the support area (A) can be increased by configuring the length of the third groove (g3) corresponding to the main guide to be longer than the length of the fourth groove (g4) corresponding to the auxiliary guide. there is.

Meanwhile, in one embodiment, the first magnet 510 may be disposed such that an action center point CP of the force generated between the first yoke 570 and the main guide is closer to the main guide than the auxiliary guide.

For example, on one side of the carrier 400, the first magnet 510 may be disposed eccentrically to one side along the longitudinal direction (eg, the first axial direction (X-axis direction)) of the first magnet 510. .

The center of one side of the carrier 400 and the center of the first magnet 510 may be misaligned. The direction in which the first magnet 510 is eccentric may be toward the main guide.

That is, the first magnet 510 may be disposed closer to the main guide than to the auxiliary guide.

Meanwhile, in another embodiment, an auxiliary yoke 590 may be disposed at a position facing the first magnet 510 . For example, the auxiliary yoke 590 may be disposed on the substrate 750 to face the first magnet 510 .

The auxiliary yoke 590 may be located closer to the main guide than the auxiliary guide. The auxiliary yoke 590 is a material capable of generating an attractive force with respect to the first magnet 510 .

Therefore, the resultant force of the attractive force acting between the first magnet 510 and the first yoke 570 and the attractive force generated between the first magnet 510 and the auxiliary yoke 590 is closer to the main guide than the auxiliary guide. can be located

Since the support area (A) is formed longer in the optical axis (Z-axis) direction as it is closer to the main guide, the resultant force of attraction between the first magnet 510, the first yoke 570 and the auxiliary yoke 590 By arranging it close to the main guide, it is possible to more stably locate the action center point CP in the support area A.

In one embodiment, the camera actuator 10 may detect the position of the carrier 400 in the optical axis (Z-axis) direction.

To this end, a first position sensor 550 is provided. The first position sensor 550 is disposed on the substrate 750 to face the first magnet 510 . The first position sensor 550 may be a hall sensor.

On the other hand, the camera actuator 10 may compensate for shaking during shooting by moving the lens module 200 in a direction perpendicular to the optical axis (Z-axis). To this end, the camera actuator includes a second driving unit 600 that moves the lens module 200 in a direction perpendicular to the optical axis (Z-axis).

It may be relatively moved in another direction perpendicular to the optical axis (Z-axis) with respect to .

For example, the guide frame 300 and the lens module 200 may move together in a direction of a first axis (X axis) perpendicular to the optical axis (Z axis), and the lens module 200 may move relative to the guide frame 300. It may be relatively moved in a second axis (Y axis) direction perpendicular to both the optical axis (Z axis) and the first axis (X axis).

The second driving unit 600 includes a first sub driving unit 610 and a second sub driving unit 630 . The first sub-driver 610 may generate driving force in the first axis (X-axis) direction, and the second sub-driver 630 may generate driving force in the second axis (Y-axis) direction.

The first sub driver 610 includes a second magnet 611 and a second coil 613 . The second magnet 611 and the second coil 613 may be disposed to face each other in the first axis (X-axis) direction.

The second magnet 611 may be disposed on the lens module 200 . For example, the second magnet 611 may be mounted on one side of the OIS frame 250 .

The second magnet 611 may be magnetized so that one surface (eg, a surface facing the second coil 613) has both an N pole and an S pole. For example, an N pole, a neutral region, and an S pole may be sequentially provided on one surface of the second magnet 611 facing the second coil 613 along the second axis (Y axis) direction. The second magnet 611 has a shape having a length in the second axis (Y axis) direction.

The other surface (eg, the opposite surface of one surface) of the second magnet 611 may be magnetized to have both an S pole and an N pole. For example, an S pole, a neutral region, and an N pole may be sequentially provided on the other surface of the second magnet 611 along the second axis (Y axis) direction.

The second coil 613 is disposed to face the second magnet 611 . For example, the second coil 613 may be disposed to face the second magnet 611 in the first axis (X-axis) direction.

The second coil 613 has a donut shape having a hollow shape and a shape having a length in the second axis (Y axis) direction. The second coil 613 may include a plurality of coils. For example, the second coil 613 may include two coils spaced apart from each other in the second axis (Y-axis) direction, and each coil may face the second magnet 611 .
