Abstract

Claims (61)

1 . A camera actuator comprising:

a housing;

a mover on which a reflective member is disposed;

a guide part disposed between the housing and the mover; and

a driving part configured to drive the mover,

wherein the guide part includes a support part, a first elastic part coupled to the support part and the mover, and a second elastic part coupled to the support part and the housing,

wherein the first elastic part supports the mover to enable tilting with respect to a first axis,

wherein the second elastic part supports the mover to enable tilting with respect to a second axis perpendicular to the first axis,

wherein the first elastic part is disposed between the support part and the mover in a third direction, and connects the support part and the mover to each other,

wherein the second elastic part is interposed between the support part and the mover in the third direction, and serves to connect the support part to the mover,

wherein the first elastic part and the second elastic part are spaced apart from each other in the third direction and are physically separated from each other, and

wherein the third direction is a direction from the guide part toward the mover and is perpendicular to a direction of the first axis and a direction of the second axis.

2 . The camera actuator of claim 1 , wherein the first elastic part and the second elastic part are disposed in directions perpendicular to each other.

3 . The camera actuator of claim 1 , wherein the support part includes:

a first support part extending in the direction of the second axis; and

a second support part extending in the direction of the first axis.

4 . The camera actuator of claim 3 , wherein the first support part is disposed apart from a line, which bisects the mover in the first axis direction, in the first axis direction.

5 . The camera actuator of claim 3 ,

wherein the first elastic part includes a first pattern disposed in the second axis direction, and;

wherein the second elastic part includes a second pattern disposed in the first axis direction.

6 . The camera actuator of claim 5 ,

wherein the housing includes a coupling hole facing the first support part,

wherein the first elastic part is coupled to the first support part and the coupling hole, and

wherein the first pattern is disposed between the first support part and the coupling hole.

7 . The camera actuator of claim 6 , wherein the first pattern is symmetrically disposed with respect to the first axis direction.

8 . The camera actuator of claim 6 ,

wherein the first elastic part further includes a first pattern region, a 1-1 coupling region, and a 1-2 coupling region disposed in the third direction,

wherein the first pattern is disposed in the first pattern region,

wherein the 1-1 coupling region is disposed between the first pattern region and the mover, and

wherein the 1-2 coupling region is disposed between the first pattern region and the housing.

9 . The camera actuator of claim 5 ,

wherein the second elastic part is coupled to the second support part and a lower surface of the mover; and

wherein the second pattern is disposed between the second support part and the lower surface of the mover.

10 . The camera actuator of claim 9 , wherein the second pattern is symmetrically disposed with respect to the first direction.

11 . The camera actuator of claim 8 ,

wherein the second elastic part further includes a second pattern region, a 2-1 coupling region, and a 2-2 coupling region in the third direction,

wherein the second pattern is disposed in the second pattern region,

wherein the 2-1 coupling region is coupled to the second support part between the second pattern and the housing, and

wherein the 2-2 coupling region is disposed between the second pattern region and the mover.

12 . The camera actuator of claim 5 ,

wherein each of the first pattern and the second pattern is provided as at least one of a groove and a hole, and

wherein the support part is disposed apart from the mover and the housing in the third direction.

13 . The camera actuator of claim 1 ,

wherein the driving part includes driving magnets and driving coils,

wherein the driving magnets include a first magnet, a second magnet, and a third magnet,

wherein the driving coils include a first coil, a second coil, and a third coil,

wherein the first magnet and the second magnet are symmetrically disposed with respect to the first axis on the mover,

wherein the first coil and the second coil are symmetrically disposed with respect to the first axis between the housing and the mover,

wherein the third magnet is disposed on a bottom surface of the mover, and

wherein the third coil is disposed on a bottom surface of the housing.

14 . A camera actuator comprising:

a housing;

a mover on which a reflective member is disposed; and

a guide part disposed between the housing and the mover and supporting the mover to enable tilting with respect to a first axis and a second axis,

wherein the guide part includes a support part, a first elastic part coupled to a first surface of the support part and a lower side of the mover, and a second elastic part coupled to a second surface of the support part and the housing,

wherein the first surface and the second surface of the support part are perpendicular to each other,

wherein one surface of the first elastic part coupled to the first surface of the support part is perpendicular to one surface of the second elastic part coupled to the second surface of the support part,

wherein the first elastic part is disposed between the support part and the mover in a third direction, and connects the support part and the mover to each other,

wherein the second elastic part is interposed between the support part and the mover in the third direction, and serves to connect the support part to the mover,

wherein the first elastic part and the second elastic part are spaced apart from each other in the third direction and are physically separated from each other, and

wherein the third direction is a direction from the guide part toward the mover and is perpendicular to a direction of the first axis and a direction of the second axis.
