AI Technical Summary
Conventional camera devices using the Module Tilt method for image stabilization face limitations in the movement of movable parts due to high resistance and performance dispersion caused by the PCB structure, particularly in compensating for rotational shake.
The camera device incorporates a system with a first substrate, an image sensor, a camera module with a lens, and driving units for rotating the camera module about multiple axes. This system uses elastic members instead of PCBs to reduce resistance and enhance movement alignment between the lens and image sensor.
The solution enables effective shake correction in three axes (yawing, pitching, and rolling) and five axes (including x-axis and y-axis shifts), reducing current consumption and minimizing the influence of camera shake during video shooting.

Abstract
Description
Technical Field
[0001] This embodiment relates to a camera device.
Background Art
[0002] With the widespread popularization of various mobile terminals and the normalization of wireless Internet services, consumer requirements related to mobile terminals have diversified, and various types of additional devices are attached to mobile terminals.
[0003] Among them, a typical one is a camera device that captures a subject in a photo or video. On the other hand, in recent camera devices, an image stabilization function for preventing the phenomenon of video shaking due to the photographer's hand shake has been applied.
[0004] One of the methods for performing the image stabilization function is the Module Tilt method. In a conventional camera device using the Module Tilt method, electrical signals of generally 20 or more image sensors are connected to a fixed part via a PCB (Printed Circuit Board) for the movement of the image sensor.
[0005] By the way, in this case, there is a problem that restrictions occur on the movement of the movable part, and a large resistance (load) also acts on the movement of the movable part. In addition, due to the dispersion of the Young's modulus of the raw materials inside the PCB and the PCB processing tolerance, the dispersion of the elastic coefficient is large, and additional work is required to reduce the performance dispersion.
[0006] In particular, since the PCB structure has high strength in the radial direction, the structure with high resistance to rotational drive is difficult to apply for compensation in the Rolling direction, that is, compensation for rotational shake.

The holes can be formed with a diameter that does not interfere with the wire 420. The holes can be formed at the corner portions of the housing 210. The holes can include a plurality of holes. The holes can be formed at each of the four corner portions of the housing 210. However, in a modification, the holes can be formed as grooves with closed bottoms. In this case, the lower ends of the wires 420 can be fixed to the housing 210.
[0074] The camera device 10A can include a coil 220. The coil 220 can be arranged in the housing 210. The coil 220 can face the magnet 320. The coil 220 can be coupled to the inner surface of the third substrate 230. The coil 220 can be electrically connected to the third substrate 230. When a current is applied to the coil 220, an electric field can be formed around the coil 220. When a current is applied to the coil 220, either the coil 220 or the magnet 320 can move relative to the other by the electromagnetic interaction between the coil 220 and the magnet 320. In this embodiment, when a current is applied to the coil 220, the magnet 320 can move. However, in a modified example, the positions of the coil 220 and the magnet 320 can be arranged opposite to each other.
[0075] The coil 220 can include a first coil 221. The first coil 221 can face the first magnet 321. The first coil 221 can be electrically separated from the second coil 222 and the third coil 223. The first coil 221 can receive an applied current separately from the second coil 222 and the third coil 223. The first coil 221 can be controlled separately from the second coil 222 and the third coil 223. When a current is applied to the first coil 221, no current may be applied to the second coil 222 and the third coil 223. Also, when a current is applied to the first coil 221, a current can be applied to the second coil 222 and the third coil 223. When no current is applied to the first coil 221, a current can be applied to the second coil 222 and the third coil 223. Of course, no current may be applied to all of the first to third coils 221, 222, 223. That is, the first to third coils 221, 222, 223 can be individually controlled. The first to third coils 221, 222, 223 can be independently controlled. In other words, the direction and amount of the current applied to each of the first to third coils 221, 222, 223 can be individually controlled. The first coil 221 can rotate the camera module 600 about a first axis perpendicular to the optical axis by interaction with the magnet 320. The first coil 221 can tilt the camera module 600 about a first axis perpendicular to the optical axis by interaction with the magnet 320. The camera module 600 can be pivotally driven about a first axis perpendicular to the optical axis. At this time, the first axis can be the x-axis.
[0076] As shown in FIG. 17(b), the first coil 221 can rotate the camera module 600 to one side about the x-axis by the interaction with the magnet 320 (see b in FIG. 17(b)). More specifically, when a positive current is applied to the first-1 coil 221-1, an upward electromagnetic interaction force (b1) is generated between the first-1 coil 221-1 and the first-1 magnet 321-1, and when a positive current is applied to the first-2 coil 221-2, a downward electromagnetic interaction force (b2) is generated between the first-2 coil 221-2 and the first-2 magnet 321-2, so that the camera module 600 can rotate to one side about the x-axis (b). However, it is not limited that the same-direction currents are applied to the first-1 coil 221-1 and the first-2 coil 221-2, and currents in other directions can be applied in a modified example. Also, currents in opposite directions can be applied to the first-1 coil 221-1 and the first-2 coil 221-2.
[0077] As shown in FIG. 18(b), the first coil 221 can rotate the camera module 600 to the other side about the x-axis by the interaction with the magnet 320 (see e in FIG. 18(b)). More specifically, when a reverse current is applied to the first-1 coil 221-1, a downward electromagnetic interaction force (e1) is generated between the first-1 coil 221-1 and the first-1 magnet 321-1, and when an upward current is applied to the first-2 coil 221-2, an upward electromagnetic interaction force (e2) is generated between the first-2 coil 221-2 and the first-2 magnet 321-2, so that the camera module 600 can rotate to the other side about the x-axis (e).
[0078] The first coil 221 can include a plurality of coils. The first coil 221 can include a first-1 coil 221-1 and a first-2 coil 221-2. The first-1 coil 221-1 can face the first-1 magnet 321-1. The first-2 coil 221-2 can face the first-2 magnet 321-2. The first-1 coil 221-1 can be arranged between the second-1 coil 222-1 and the second-2 coil 222-2. The first-2 coil 221-2 can be arranged between the second-3 coil 222-3 and the second-4 coil 222-4. The first-1 coil 221-1 and the first-2 coil 221-2 can be electrically connected. Thereby, the first-1 coil 221-1 and the first-2 coil 221-2 can be controlled integrally. However, in other examples, the first-1 coil 221-1 and the first-2 coil 221-2 can be electrically separated. The first-1 coil 221-1 and the first-2 coil 221-2 can receive the application of current individually. In this case, the first-1 coil 221-1 and the first-2 coil 221-2 can be controlled individually. That is, the direction and amount of the current applied to each of the first-1 coil 221-1 and the first-2 coil 221-2 can be controlled individually.
[0079] The coil 220 can include a second coil 222. The second coil 222 can face the first magnet 321. The second coil 222 can be electrically separated from the first coil 221. The second coil 222 and the first coil 221 can receive the application of current individually. The second coil 222 and the first coil 221 can be controlled individually. The second coil 222 can rotate the camera module 600 about a second axis perpendicular to the optical axis and the first axis by the interaction with the magnet 320. The second coil 222 can tilt the camera module 600 about a second axis perpendicular to the optical axis and the first axis by the interaction with the magnet 320. The camera module 600 can be pivotally driven about a second axis perpendicular to the optical axis and the first axis. At this time, the second axis can be the y-axis.
[0080] As shown in FIG. 17(a), the second coil 222 can rotate the camera module 600 to one side about the y-axis due to the interaction with the magnet 320 (see a in FIG. 17(a)). More specifically, when a positive current is applied to the second-1 coil 222-1, an upward electromagnetic interaction force (a1) is generated between the second-1 coil 222-1 and the first-1 magnet 321-1. When a positive current is applied to the second-3 coil 222-3, an upward electromagnetic interaction force (a1) is generated between the second-3 coil 222-3 and the first-2 magnet 321-2. When a reverse current is applied to the second-2 coil 222-2, a downward electromagnetic interaction force (a2) is generated between the second-2 coil 222-2 and the first-1 magnet 321-1. When a reverse current is applied to the second-4 coil 222-4, a downward electromagnetic interaction force (a2) is generated between the second-4 coil 222-4 and the first-2 magnet 321-2, and the camera module 600 can rotate to one side about the y-axis (a). The electromagnetic interaction force (a1) between the second-1 coil 222-1 and the first-1 magnet 321-1 and the electromagnetic interaction force (a1) between the second-3 coil 222-3 and the first-2 magnet 321-2 are in the same direction. The electromagnetic interaction force (a2) between the second-2 coil 222-2 and the first-1 magnet 321-1 and the electromagnetic interaction force (a2) between the second-4 coil 222-4 and the first-2 magnet 321-2 are in the same direction, but the electromagnetic interaction force (a1) between the second-1 coil 222-1 and the first-1 magnet 321-1 and the electromagnetic interaction force (a2) between the second-2 coil 222-2 and the first-1 magnet 321-1 can be in different directions. As an example, the electromagnetic interaction force (a1) between the second-1 coil 222-1 and the first-1 magnet 321-1 and the electromagnetic interaction force (a1) between the second-3 coil 222-3 and the first-2 magnet 321-2 can be upward, and the electromagnetic interaction force (a2) between the second-2 coil 222-2 and the first-1 magnet 321-1 and the electromagnetic interaction force (a2) between the second-4 coil 222-4 and the first-2 magnet 321-2 can be downward.It is described that currents in different directions are applied to the second - 1 coil 222 - 1 and the second - 2 coil 222 - 2. However, in a modified example, the winding directions of the coils can be arranged in opposite directions to each other, and currents in the same direction can be applied.
[0081] As shown in FIG. 17(a), the second coil 222 can rotate the camera module 600 in the other direction about the y - axis (see d in FIG. 17(a)) by the interaction with the magnet 320. More specifically, when a current in the reverse direction is applied to the second - 1 coil 222 - 1, a downward electromagnetic interaction force (d1) is generated between the second - 1 coil 222 - 1 and the first - 1 magnet 321 - 1. When a current in the reverse direction is applied to the second - 3 coil 222 - 3, a downward electromagnetic interaction force (d1) is generated between the second - 3 coil 222 - 3 and the first - 2 magnet 321 - 2. When a current in the forward direction is applied to the second - 2 coil 222 - 2, an upward electromagnetic interaction force (d2) is generated between the second - 2 coil 222 - 2 and the first - 1 magnet 321 - 1. When a current in the forward direction is applied to the second - 4 coil 222 - 4, an upward electromagnetic interaction force (d2) is generated between the second - 4 coil 222 - 4 and the first - 2 magnet 321 - 2, and the camera module 600 can rotate in the other direction (d) about the y - axis.
[0082] The second coil 222 can include a plurality of coils. The second coil 222 can include coils 222-1, 222-2, 222-3, and 222-4. Coil 222-1 can face magnet 321-1. Coil 222-1 can be arranged on one side of coil 221-1. Coil 222-2 can face magnet 321-1. Coil 222-2 can be arranged on the other side of coil 221-1. Coil 222-3 can face magnet 321-2. Coil 222-3 can be arranged on one side of coil 221-2. Coil 222-4 can face magnet 321-2. Coil 222-4 can be arranged on the other side of coil 221-2.
[0083] Coils 222-1, 222-2, 222-3, and 222-4 can be electrically connected. Thereby, coils 222-1, 222-2, 222-3, and 222-4 can be controlled integrally. However, in other examples, coils 222-1, 222-2, 222-3, and 222-4 can all be electrically separated. In this case, coils 222-1, 222-2, 222-3, and 222-4 can be controlled individually. That is, the direction and amount of current applied to each of coils 222-1, 222-2, 222-3, and 222-4 can be controlled individually. In yet another example, coil 222-1 and coil 222-3 are electrically connected, coil 222-2 and coil 222-4 are electrically connected, and coil 222-1 and coil 222-2 can be electrically separated.
[0084] The coil 220 may include a third coil 223. The third coil 223 can face the second magnet 322. The third coil 223 can be electrically separated from the first coil 221 and the second coil 222. The third coil 223 can receive an applied current separately from any one or more of the first coil 221 and the second coil 222. The third coil 223 can be individually controlled from any one or more of the first coil 221 and the second coil 222.
[0085] As shown in FIG. 17(c), the third coil 223 can rotate the camera module 600 to one side about the optical axis by the interaction with the magnet 320 (see c in FIG. 17(c)). More specifically, when a positive current is applied to the third - 1 coil 223 - 1, an electromagnetic interaction force (c1) in the first direction is generated between the third - 1 coil 223 - 1 and the second - 1 magnet 322 - 1. When a positive current is applied to the third - 2 coil 223 - 2, an electromagnetic interaction force (c2) in the second direction is generated between the third - 2 coil 223 - 2 and the second - 2 magnet 322 - 2, and the camera module 600 can rotate (c) about the z - axis to one side. At this time, the first direction and the second direction are each the tangent direction of a circle centered on the optical axis and can be symmetric with each other along the optical axis. Although it has been described that positive currents are applied to each of the third - 1 coil 223 - 1 and the third - 2 coil 223 - 2, in a modified example, currents in different directions can be applied to the third - 1 coil 223 - 1 and the third - 2 coil 223 - 2. At this time, the required electromagnetic interaction force can be induced according to the arrangement direction of the second - 1 magnet 322 - 1 and the second - 2 magnet 322 - 2 or the winding direction of the third - 1 coil 223 - 1 and the third - 2 coil 223 - 2.
[0086] As shown in FIG. 17(c), the third coil 223 can rotate the camera module 600 in the other direction about the optical axis by the interaction with the magnet 320 (see f in FIG. 17(c)). More specifically, when a current in the reverse direction is applied to the first third coil 223-1, an electromagnetic interaction force (f1) in the third direction is generated between the first third coil 223-1 and the first second magnet 322-1. When a current in the reverse direction is applied to the second third coil 223-2, an electromagnetic interaction force (f2) in the fourth direction is generated between the second third coil 223-2 and the second second magnet 322-2, and the camera module 600 can rotate (f) in the other direction about the z-axis. At this time, the third direction and the fourth direction are each a tangential direction of a circle centered on the optical axis and can be symmetric with each other along the optical axis. Also, the third direction can be the opposite direction of the first direction, and the fourth direction can be the opposite direction of the second direction.
[0087] The third coil 223 can include a plurality of coils. The third coil 223 can include a first third coil 223-1 and a second third coil 223-2. The first third coil 223-1 can face the first second magnet 322-1. The second third coil 223-2 can face the second second magnet 322-2. The first third coil 223-1 and the second third coil 223-2 can be electrically connected. Thereby, the first third coil 223-1 and the second third coil 223-2 can be controlled integrally. However, in other examples, the first third coil 223-1 and the second third coil 223-2 can be electrically separated. In this case, the first third coil 223-1 and the second third coil 223-2 can be controlled individually. That is, the direction and amount of the current applied to each of the first third coil 223-1 and the second third coil 223-2 can be controlled individually.

[0099] The magnet 320 can include a first magnet 321. The first magnet 321 can be arranged on each of the first side surface and the second side surface of the camera module 600. The upper and lower polarities of the surface of the first magnet 321 facing the coil 220 can be different. The first magnet 321 can be a single magnet having two poles. However, as a modification, the first magnet 321 can be a north-pole magnetized magnet in a form in which two single magnets having two poles overlap. The upper part of the first magnet 321 can be an N pole, and the lower part can be an S pole. However, in a modification, the upper part of the first magnet 321 can be an S pole, and the lower part can be an N pole. The first magnet 321 can face the first coil 221 and the second coil 222. The horizontal width of the first magnet 321 can correspond to the combined width of the first coil 221 and the second coil 222.
[0100] The first magnet 321 can include a first-1 magnet 321-1 and a first-2 magnet 321-2. The first-1 magnet 321-1 can be arranged on the first side surface of the camera module 600. The first-2 magnet 321-2 can be arranged on the second side surface of the camera module 600.

[0102] The second magnet 322 can be a single magnet with two poles. However, as a modification, the second magnet 322 can be a positively magnetized magnet in a form where two single magnets with two poles overlap. One side portion of the second magnet 322 can be an N pole, and the other side portion can be an S pole. However, in a modification, one side portion of the second magnet 322 can be an S pole, and the other side portion can be an N pole.

[0104] The camera device 10A can include an upper elastic member 410. A part of the upper elastic member 410 can be coupled to the holder 310. The upper elastic member 410 can be fixed to the protrusion 312 of the holder 310 by an adhesive. The upper elastic member 410 can connect the holder 310 and the wire 420. The upper elastic member 410 can be elastic at least in part. The upper elastic member 410 can include a leaf spring.
[0105] As shown in FIGS. 17 and 18, in this embodiment, a contact support structure can be applied to the central portion of the lower surface of the camera module 600. At this time, the upper elastic member 410 provided with a leaf spring is formed to be offset bent after the base 110 is assembled, so that a preload structure in which the entire camera module 600 receives a force in the direction of the base 110 is formed, and the posture difference sag due to gravity can be prevented. This embodiment has a structure in which the upper elastic member 410 is offset bent and a pre-load is applied in the product assembly state. In this embodiment, even if a change in the gravitational direction occurs, the preload, which is a vertical resistance, is sufficiently large compared to the weight of the camera module 600, and the camera module 600 does not sag due to the posture difference. Referring to FIG. 15, an offset bending structure that generates a height difference (see a in FIG. 15) existing between the first coupling portion 411 and the second coupling portion 412 of the upper elastic member 410 can be confirmed. In this embodiment, the offset bending shape of the upper elastic member 410 can be maintained in any of the postures in which the camera module 600 photographs upward, the camera module 600 photographs downward, and the camera module 600 photographs sideways. In other words, the offset bending shape of the upper elastic member 410 can be maintained in any of the postures in which the lens 625 of the camera module 600 is disposed above the image sensor 695, the lens 625 of the camera module 600 is disposed below the image sensor 695, and the centers of the lens 625 and the image sensor 695 of the camera module 600 are disposed at the same height. Thereby, the posture difference sag of the camera module 600 can be prevented. Due to the preload of the upper elastic member 410, a frictional force (F) acts between the camera module 600 and the protruding portion 121-1 of the elastic member 120, whereby the posture difference sag can be prevented. However, the offset bending amount of the upper elastic member 410 can change according to the posture.
[0106] The upper elastic member 410 can include a first coupling portion 411. The first coupling portion 411 can be coupled to the holder 310.
