Description

Technical Field

[0001] The present invention relates to a camera actuator and a camera device including the same.

Background Art

[0002] A camera is a device that captures a subject in a photograph or video, and is mounted on a portable device, a drone, a vehicle, etc. The camera device has an image stabilization (IS) function that corrects or prevents image blur caused by the movement of the user to improve the quality of the video, an autofocusing (AF) function that automatically adjusts the distance between the image sensor and the lens to align the focal length of the lens, and a zooming function that increases or decreases the magnification of a distant subject through a zoom lens for shooting.

[0003] On the other hand, as the image sensor has a higher resolution and a smaller pixel size as the number of pixels increases, the amount of light received in the same time decreases as the pixel size decreases. Therefore, in a darker environment, the shutter speed becomes slower in a higher pixel camera, and the image blur phenomenon due to camera shake appears more severely. As a typical example of the image stabilization IS technology, there is an optical image stabilizer (OIS) technology that corrects movement by changing the optical path.

[0004] According to the general OIS technology, the movement of the camera is sensed through a gyro sensor or the like, and based on the sensed movement, the lens can be tilted or moved, or the camera module including the lens and the image sensor can be tilted or moved. When the lens or the camera module including the lens and the image sensor tilts or moves for OIS, an additional space for tilting or moving needs to be secured around the lens or the camera module.

[0005] On the other hand, actuators for OIS may be positioned around the lens. In this case, the actuators for OIS may include actuators responsible for tilting along two axes perpendicular to the optical axis.

[0006] However, due to the need for ultra-slim and ultra-compact camera devices, there are significant spatial constraints for placing actuators for OIS, and it may be difficult to ensure sufficient space for the lens or the camera module itself, including the lens and image sensor, to tilt or move for OIS. Also, while it is preferable for higher-resolution cameras to have larger lenses to increase the amount of light received, the space occupied by the OIS actuators may limit how large the lens can be.

[0007] Furthermore, if the camera device includes zooming, autofocus, and optical image stabilization (OIS) functions, there is a problem where the magnets for OIS and those for AF or zoom are placed close together, causing magnetic field interference.

[0038] While the present invention can be modified in various ways and has a variety of embodiments, specific embodiments will be illustrated and explained in the drawings. However, this should not be understood as limiting the present invention to specific embodiments, but rather as including all modifications, equivalents, or substitutes that fall within the spirit and technical scope of the present invention.

[0039] Terms including ordinal numbers, such as "second," "first," etc., can be used to describe a variety of components, but the components are not limited by the terms. The terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the second component may be named the first component, and similarly, the first component may be named the second component. The terms "and" and / or include a combination of multiple related described items or any of the multiple related described items.

[0040] When it is mentioned that one component is "linked" or "connected" to another component, it should be understood that it may be directly linked or connected to the other component, but there may also be other components in between. Conversely, when it is mentioned that one component is "directly linked" or "directly connected" to another component, it should be understood that there are no other components in between.

[0041] The terminology used in this application is used solely to describe specific embodiments and is not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this application, terms such as “includes” or “having” are intended to specify the existence of features, figures, stages, operations, components, parts, or combinations thereof described in the specification, and should be understood not to preemptively exclude the possibility of the existence or addition of one or more other features, figures, stages, operations, components, parts, or combinations thereof.

[0042] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as those generally understood by a person of ordinary skill in the art to which this invention pertains. Terms as defined in commonly used dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art, and not in an ideal or overly formal sense unless expressly defined herein.

[0043] The embodiments will be described in detail below with reference to the attached drawings. Regardless of the reference numerals used in the drawings, identical or corresponding components will be assigned the same reference numerals, and redundant explanations will be omitted.

[0044] Figure 1 is a perspective view of a camera module according to an embodiment, Figure 2a is a perspective view of the camera module shown in Figure 1 with the shield can removed, and Figure 2b is a plan view of the camera module shown in Figure 2a.

[0045] Referring to Figure 1, the camera module 1000 may include one or more camera modules. For example, the camera module 1000 may include a first camera module 1000A and a second camera module 1000B. The first camera module 1000A and the second camera module 1000B may be covered by a predetermined shield can 1210.

[0046] Referring to Figures 1, 2a, and 2b together, the first camera module 1000A can include one or more actuators. For example, the first camera module 1000A can include a first camera actuator 1100 and a second camera actuator 1200.

[0047] The first camera actuator 1100 may be electrically connected to the first group of circuit boards 1410, and the second camera actuator 1200 may be electrically connected to the second group of circuit boards 1420. Although not shown, the second group of circuit boards 1420 may also be electrically connected to the first group of circuit boards 1410. The second camera module 1000B may be electrically connected to the third group of circuit boards 1430.

[0048] The first camera actuator 1100 may be a zoom actuator or an autofocus (AF) actuator. For example, the first camera actuator 1100 may support one or more lenses and move the lenses according to a control signal from a predetermined control unit to perform an autofocus function or a zoom function.

[0049] The second camera actuator 1200 may be an OIS (Optical Image Stabilizer) actuator.

[0050] The second camera module 1000B may include a lens positioned in a predetermined lens barrel (not shown). The lens may be a fixed focal length lens. A fixed focal length lens may also be referred to as a "single focal length lens" or "single lens".

[0051] The second camera module 1000B is housed in a predetermined housing (not shown) and may include an actuator (not shown) capable of driving the lens. The actuator may be a voice coil motor, a microactuator, a silicon actuator, etc., and may be applied in a variety of ways, such as electrostatic, thermal, bimorph, or electrostatic force.

[0052] Next, Figure 3a is a perspective view of the first camera module shown in Figure 2a, and Figure 3b is a side cross-sectional view of the first camera module shown in Figure 3a.

[0053] Referring to Figure 3a, the first camera module 1000A may include a first camera actuator 1100 that performs zooming and autofocus functions, and a second camera actuator 1200 positioned on one side of the first camera actuator 1100 that performs OIS functions.

[0054] Referring to Figure 3b, the first camera actuator 1100 may include an optical system and a lens drive unit. For example, the first actuator 1100 may have at least one of the following: a first lens assembly 1110, a second lens assembly 1120, a third lens assembly 1130, and a guide pin 50.

[0055] Furthermore, the first camera actuator 1100 is equipped with a drive coil 1140 and a drive magnet 1160, enabling it to perform a high-magnification zooming function.

[0056] For example, the first lens assembly 1110 and the second lens assembly 1120 may be moving lenses that move via a drive coil 1140, a drive magnet 1160, and a guide pin 50, and the third lens assembly 1130 may be a fixed lens, but is not limited to this. For example, the third lens assembly 1130 can perform the function of a focator that focuses light at a specific position, and the first lens assembly 1110 can perform the function of a variator that re-images the image formed by the third lens assembly 1130 (which is the focator) to another location. On the other hand, the first lens assembly 1110 may experience large changes in magnification due to changes in the distance to the subject or the distance to the image, and the first lens assembly 1110, as a variator, can play an important role in the change of focal length or magnification of the optical system. On the other hand, the image point formed by the first lens assembly 1110 (which is the variator) may differ slightly depending on the position. In response to this, the second lens assembly 1120 can perform a position compensation function for the image formed by the variator. For example, the second lens assembly 1120 can perform a compensator function, which involves precisely imaging the image point formed by the first lens assembly 1110, which is a magnifier, onto the actual position of the image sensor 1190.

[0057] For example, the first lens assembly 1110 and the second lens assembly 1120 can be driven by an electromagnetic force resulting from the interaction between the drive coil 1140 and the drive magnet 1160.

[0058] Furthermore, a predetermined image sensor 1190 may be arranged perpendicular to the optical axis direction of parallel light.

[0059] Next, a detailed explanation of the second camera actuator 1200 will be provided in Figure 4 and subsequent figures.

[0060] Furthermore, the camera module according to the embodiment can implement OIS through control of the optical path via a camera actuator, thereby minimizing the occurrence of descent and tilt phenomena and exhibiting optimal optical characteristics.

[0061] Figures 1 to 3a, b and their accompanying descriptions are intended to illustrate the overall structure and operating principle of a camera module according to an embodiment of the present invention; therefore, the embodiment of the present invention is not limited to the detailed configurations shown in Figures 1 to 3a, b.

[0062] On the other hand, when the OIS actuator and the AF or zoom actuator are arranged according to the embodiment of the present invention, magnetic field interference with the AF or zoom magnet can be prevented when the OIS is driven. Since the drive magnet of the second camera actuator 1200 is arranged separately from the first actuator 1100, magnetic field interference between the first actuator 1100 and the second actuator 1200 can be prevented. In this specification, OIS may be used interchangeably with terms such as image stabilization, optical image stabilization, optical image correction, and shake correction.

[0063] The control method and detailed structure of the second actuator according to one embodiment of the present invention will be described in more detail below.

[0064] Figure 4 is a perspective view of the second camera actuator according to the embodiment, and Figure 5 is an exploded perspective view of the second camera actuator according to the embodiment.

[0065] Referring to Figures 4 and 5, the second camera actuator 1200 according to the embodiment includes a shield can 1210, a housing 1220, a mover 1230, a guide section 1240, and a drive section 1250. It should be understood that the components are not assembled along the lines shown in this exploded perspective view (e.g., the dashed lines).

[0066] First, the mover 1230 includes a holder 1231 and an optical member 1232 mounted on the holder 1231. The guide section 1240 includes a support section 1241, a first elastic section 1242 connecting the support section 1241 and the housing 1220, and a second elastic section 1243 connecting the support section 1241 and the mover 1230. The guide section 1240 can perform tilt around two axes through the first elastic section 1242 and the second elastic section 1243. In one embodiment, the guide section 1240 can rotate with respect to a first direction (X-axis direction) by the first elastic section 1242 (corresponding to tilt around the second axis). The guide section 1240 can also rotate with respect to a second direction (Y-axis direction) by the second elastic section 1243 (corresponding to tilt around the first axis). The drive unit 1250 also includes a drive magnet 1251, a drive coil 1252, a Hall sensor unit 1253, a coupling unit 1254, and a substrate unit 1255. Each component will be described below.

[0067] The shield can 1210 can be positioned in one area of ​​the second camera actuator 1200 (for example, the outermost area) and can surround the guide section 1240 and the drive section 1250, which will be described later.

[0068] Such a shielding can 1210 can block or reduce electromagnetic waves generated externally. Consequently, the occurrence of malfunctions in the guide section 1240 or the drive section 1250 may be reduced.

[0069] The housing 1220 can be located inside the shield can 1210. Alternatively, the housing 1220 can be located inside the substrate portion 1255. The housing 1220 can be inserted into or joined with the shield can 1210 and fastened together.

[0070] The housing 1220 may include multiple housing sides. For example, the housing 1220 may include a first to fifth housing side. A detailed explanation of this will follow later.

[0071] The housing 1220 may include a dwelling section 1226, which is a cavity, between multiple housing sides.

[0072] The mover 1230 includes a holder 1231 and an optical element 1232 that is mounted on the holder 1231.

[0073] The holder 1231 can be mounted in the housing portion 1226 of the housing 1220. The holder 1231 may include outer surfaces of the first to fourth holders corresponding to the first, second, third, and fourth housing sides, respectively. A detailed explanation of this will follow later.

[0074] The optical element 1232 can be mounted on the holder 1231. For this purpose, the holder 1231 may have a mounting portion, which may be formed by a housing portion. The optical element 1232 may include, but is not limited to, a reflective portion located inside. The optical element 1232 can reflect light reflected from the outside (e.g., an object) into the camera module. In other words, the optical element 1232 can improve the spatial limitations of the first and second camera actuators by altering the path of the reflected light. It should be understood that this also allows the camera module to provide a wide range of magnification by extending the light path while minimizing its thickness.

[0075] Such optical components 1232 may include reflective members such as prisms or mirrors. The optical components may further include at least one lens before or after the reflective member.

[0076] The guide section 1240 may be positioned within the housing 1220. Furthermore, as mentioned above, the guide section 1240 allows the mover 1230 to tilt along its first and second axes via the first elastic section 1242 and the second elastic section 1243. A more detailed explanation of this will follow later.

[0077] The drive unit 1250 includes a drive magnet 1251, a drive coil 1252, a Hall sensor unit 1253, a coupling unit 1254, and a substrate unit 1255.

[0078] The drive magnet 1251 can include multiple magnets. In one embodiment, the drive magnet 1251 can include a first magnet 1251a, a second magnet 1251b, and a third magnet 1251c.

[0079] The first magnet 1251a, the second magnet 1251b, and the third magnet 1251c can each be positioned on the outer surface of the holder 1231. The first magnet 1251a and the second magnet 1251b can be positioned facing each other. The third magnet 1251c can be positioned on the bottom surface of the outer surface of the holder 1231. A more detailed explanation of this will follow later.

[0080] The drive coil 1252 may include multiple coils. For example, the drive coil 1252 may include a first coil 1252a, a second coil 1252b, and a third coil 1252c.

[0081] The first coil 1252a can be positioned opposite the first magnet 1251a. This allows the first coil 1252a to be positioned in the first housing hole 1221a of the first housing side portion 1221, as described above.

[0082] Furthermore, the second coil 1252b can be positioned opposite the second magnet 1251b. This allows the second coil 1252b to be located in the second housing hole 1222a of the second housing side portion 1222, as described above.

[0083] The first coil 1252a can be positioned opposite the second coil 1252b. That is, the first coil 1252a can be positioned symmetrically with respect to the first direction relative to the second coil 1252b. This can also be applied equally to the first magnet 1251a and the second magnet 1251b. With such a configuration, the electromagnetic force between the first coil 1252a and the first magnet 1251a and the electromagnetic force between the second coil 1252b and the second magnet 1251b can accurately cause X-axis tilting without tilting to one side.

[0084] The third coil 1252c can be positioned opposite the third magnet 1251c. This allows the second coil 1252c to be positioned in the third housing hole 1223a of the third housing side 1223, as described above. The third coil 1252c generates an electromagnetic force with the third magnet 1251c, enabling the mover 1230 and guide section 1240 to perform Y-axis tilting with respect to the housing 1220.

[0085] Here, X-axis tilting means tilting with the X-axis as the reference (or reference axis), and Y-axis tilting means tilting with the Y-axis as the reference (or reference axis). The first direction is the X-axis direction in the drawing and can be used interchangeably with the second axis direction, second axis, etc. The second direction is the Y-axis direction in the drawing and can be used interchangeably with the first axis direction, first axis, etc. The second direction is perpendicular to the first direction. The third direction is the Z-axis direction in the drawing and can be used interchangeably with the third axis direction, etc. The third direction is perpendicular to both the first and second directions. In this invention, the first direction (X-axis direction) corresponds to the direction of the optical axis with respect to the light incident on the second camera actuator, and the second direction (Y-axis direction) and the third direction (Z-axis direction) are perpendicular to the optical axis and can be tilted by the second camera actuator. Such a third direction may correspond to the direction from the guide part toward the optical member or holder. Furthermore, the bottom surface refers to one side in the first direction, and in the housing, the third housing side may be the bottom surface, the inside is the direction toward the center of the camera actuator, and the outside may be the opposite direction. This specification should be understood based on the above. However, since the second camera actuator moves light to the image sensor in the first camera actuator through the optical member, the optical axis will be described with reference to the third direction, i.e., the Z-axis direction. It should be understood that the optical axis can be changed to the Z-axis within the first camera actuator, as will be described later. In addition, since the second camera actuator performs rotation in the first and second directions perpendicular to the third direction, which is the optical axis, it can perform OIS (Optical Isolation System) functionality.

[0086] The Hall sensor unit 1253 can include multiple Hall sensors. In one embodiment, the Hall sensor unit 1253 can include a first Hall sensor 1253a, a second Hall sensor 1253b, and a third Hall sensor 1253c. The first Hall sensor 1253a and the second Hall sensor 1253b can be located inside the first coil 1252a or the second coil 1252b. The first Hall sensor 1253a and the second Hall sensor 1253b can sense changes in magnetic flux inside the first coil 1252a or the second coil 1252b. This enables position sensing between the first and second magnets 1251a and 1251b and the first Hall sensor 1253a and the second Hall sensor 1253b. The camera actuator according to this embodiment can control X-axis tilt through this.

[0087] Furthermore, the third Hall sensor 1253c can be positioned inside the third coil 1252c. The third Hall sensor 1253c can sense changes in magnetic flux inside the third coil 1252c. This allows for position sensing between the third magnet 1251c and the third Hall sensor 1253c. The camera actuator according to this embodiment can control Y-axis tilt through this.

[0088] The connecting portion 1254 may include a first connecting member 1254a, a second connecting member 1254b, and a third connecting member 1254c.

[0089] The first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c can each be positioned in a mounting groove formed on the outer surface of the holder 1231. The first connecting member 1254a and the second connecting member 1254b can be positioned facing each other. The third connecting member 1254c can be positioned on the bottom surface of the outer surface of the holder 1231 (e.g., the outer surface of the third holder).

[0090] Furthermore, the first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c can each be positioned between the first magnet 1251a to the third magnet 1251c and the holder 1231.

[0091] The first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c can be yokes. Accordingly, the first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c can each be connected to the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c, respectively.

[0092] Furthermore, the first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c are each positioned within the first mounting groove, the second mounting groove, and the third mounting groove, and can be easily bonded to the first mounting groove, the second mounting groove, and the third mounting groove through adhesive members injected through grooves formed in the first mounting groove, the second mounting groove, and the third mounting groove.

[0093] As a result, the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c can be easily connected to the holder 1231 by the first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c.

[0094] The first magnet 1251a, the second magnet 1251b, and the third magnet 1251c can each be positioned on the outer surface of the holder 1231. The first magnet 1251a and the second magnet 1251b can be positioned facing each other. The third magnet 1251c can be positioned on the bottom surface of the outer surface of the holder 1231. A more detailed explanation of this will follow later.

[0095] The substrate portion 1255 can be located below the drive unit 1250. The substrate portion 1255 can be electrically connected to the drive coil 1252 and the Hall sensor portion 1253. For example, the substrate portion 1255 can be connected to the drive coil 1252 and the Hall sensor portion 1253 and the SMT. However, it is not limited to this configuration.

[0096] The substrate portion 1255 is located between the shield can 1210 and the housing 1220, and can be coupled to the shield can 1210 and the housing 1220. As described above, various coupling methods are possible. Through the aforementioned coupling, the drive coil 1252 and the Hall sensor portion 1253 can be positioned within the outer surface of the housing 1220.

[0097] Such a substrate portion 1255 may include circuit boards with electrically connectable wiring patterns, such as rigid PCBs, flexible PCBs, and rigid-flexible PCBs. However, it is not limited to these types.

[0098] Figure 6a is a perspective view of the housing according to the embodiment, Figure 6b is a side view of the fourth housing side seen from the housing according to the embodiment, Figure 6c is a side view of the fifth housing side seen, Figure 6d is a side view of the first housing side and the second housing side seen, Figure 6e is a top view of the housing according to the embodiment, and Figure 6f is a bottom view of the housing according to the embodiment.

[0099] Referring to Figures 6a to 6g, the housing 1220 may include a first housing side 1221, a second housing side 1222, a third housing side 1223, a fourth housing side 1224, and a fifth housing side 1225.

[0100] The first housing side 1221 and the second housing side 1222 may be positioned opposite each other, or they may be positioned corresponding to each other with respect to a first direction. Additionally, the third housing side 1223 may be positioned on the bottom surface of the housing 1220. The fourth housing side 1224 and the fifth housing side 1225 may be positioned opposite each other and located between the first housing side 1221 and the second housing side 1222. Furthermore, the fourth housing side 1224 and the fifth housing side 1225 may be positioned corresponding to each other with respect to a first direction.

[0101] The third housing side portion 1223 can be in contact with the first housing side portion 1221, the second housing side portion 1222, the fourth housing side portion 1224, and the fifth housing side portion 1225.

[0102] The first housing side portion 1221 may include a first housing hole 1221a. A first coil, described later, can be located in the first housing hole 1221a.

[0103] The first housing side portion 1221 may include a first coupling projection (not shown). Through the first coupling projection (not shown), the first housing side portion 1221 can be easily coupled to the substrate portion.

[0104] Furthermore, the first housing side portion 1221 may include a first mounting projection 1221c. The first mounting projection 1221c may be located on the upper or lower part of the first housing side portion 1221. The first mounting projection 1221c can easily support the substrate portion. This may improve the bonding force between the first housing side portion and the substrate portion.

[0105] Furthermore, the second housing side portion 1222 may include a second housing hole 1222a. A second coil, which will be described later, can be positioned in the second housing hole 1222a.

[0106] The first housing hole 1221a and the second housing hole 1222a can be positioned opposite each other. For example, the first housing hole 1221a and the second housing hole 1222a can be arranged symmetrically with respect to a first direction (X-axis direction) or a third direction (Z-axis direction). The first coil and the second coil can be electrically connected and coupled to a substrate located outside the housing 1220 through the first housing hole 1221a and the second housing hole 1222a. The first coil and the second coil can be electrically connected to the substrate and current can flow. Such current is an element of electromagnetic force that allows the second camera actuator to tilt with respect to the X-axis.

[0107] The second housing side portion 1222 may include a second coupling projection (not shown). The second housing side portion 1222 can be easily coupled to the substrate portion through the second coupling projection (not shown).

[0108] Furthermore, the second housing side portion 1222 may include a second mounting projection 1222c. The second mounting projection 1222c can be located on the upper or lower part of the second housing side portion 1222. The second mounting projection 1222c can easily support the substrate portion. This may improve the bonding force between the second housing side portion and the substrate portion.

[0109] Furthermore, the third housing side portion 1223 may include a third housing hole 1223a. A third coil, described later, can be located in the third housing hole 1223a. The third coil can be coupled to the substrate portion. In one embodiment, the third coil can be electrically connected to the substrate portion 1255 so that current can flow. Such current is an element of electromagnetic force that allows the second camera actuator to tilt with respect to the Y-axis.

[0110] The third housing side portion 1223 may include a third coupling projection (not shown). Through the third coupling projection (not shown), the third housing side portion 1223 can be easily coupled to the substrate portion.

[0111] The fourth housing side 1224 can be in contact with the first housing side 1221, the second housing side 1222, and the third housing side 1223. In particular, the fourth housing side 1224 may be positioned on the third housing side 1223. The lower surface of the fourth housing side 1224 may be in contact with the upper surface of the third housing side 1223, and the fourth housing side 1224 may be supported by the third housing side 1223. The fourth housing side 1224 may not be positioned in the path of light.

[0112] The fourth housing side portion 1224 can include a coupling hole CH. This allows the fourth housing side portion 1224 to include the inner surface CHS of the coupling hole CH. Furthermore, the fourth housing side portion 1224 can include a projection CHP located on the inner surface CHS.

[0113] The protruding portion CHP can be positioned on the bisector in the second direction (Y-axis direction) at the fourth housing side portion 1224. The coupling hole CH can be positioned to correspond to the first support portion of the support portion described later. In one embodiment, the coupling hole CH can overlap with the first support portion of the support portion in the third direction (Z-axis direction).

[0114] Furthermore, a first support portion may be attached to the coupling hole CH. Accordingly, the first support portion and the fourth housing side portion 1224 can be coupled to each other.

[0115] In the coupling hole CH, the protrusion CHP can be positioned on the surface CHS facing the second direction (Y-axis direction). That is, if the protrusion CHP is positioned on the surface CHS' facing the first direction (X-axis direction) in the coupling hole CH, the relative first support can be easily inserted into and coupled to the coupling hole CH.

[0116] The fifth housing side 1225 may be positioned opposite the fourth housing side 1224. The fifth housing side 1225 may include an opening 1225a. This allows light that has passed through or been reflected by the optical member to move through the opening 1225a.

[0117] Furthermore, the fifth housing side portion 1225 may include a housing projection 1225b. The housing projection 1225b may protrude outward. The housing 1220 can be coupled to the first camera actuator located on the outside via the housing projection 1225b. This may improve the reliability of the camera module.

[0118] Furthermore, the fifth housing side portion 1225 may include a patterned portion (not shown) having a pattern around the housing projection 1225b. The patterned portion (not shown) may be positioned with a step inside the housing projection 1225b. That is, the patterned portion (not shown) may be located inside the housing projection 1225b.

[0119] An adhesive may be applied to the patterned portion (not shown). Consequently, the contact area between the adhesive and the fifth housing side portion 1225 on the patterned portion (not shown) may increase. This may increase the coupling force between the second actuator (or housing 1220) and the first actuator.

[0120] Furthermore, the housing 1220 may include a accommodating section 1226 formed inward by the first to fifth housing sides 1221 to 1225. A mover 1230 and a guide section 1240 can be located in the accommodating section 1226.

[0121] Figure 7a is a perspective view of the mover according to the embodiment, Figure 7b is a perspective view of the holder according to the embodiment, Figure 7c is a side view of the mover according to the embodiment, and Figure 7d is a bottom view of the mover according to the embodiment.

[0122] Referring to Figures 7a to 7d, the mover 1230 according to the embodiment may include a holder 1231 and an optical member 1232 mounted on the holder 1231.

[0123] First, the optical element 1232 can be mounted on the holder 1231. As mentioned above, such an optical element 1232 may be a prism or a mirror, but is not limited to these.

[0124] Furthermore, the holder 1231 may include a mounting portion 1231k to which the optical member 1232 is attached. The mounting portion 1231k may be an inclined surface. Also, the holder 1231 may include a stepped portion SP at its lower part. In the holder 1231, the stepped portion SP can prevent the optical member 1232 from moving. Through this, light incident from the upper part can travel along the third direction (Z-axis direction) by passing through the optical member 1232 and the opening on the side of the fifth housing mentioned above.

[0125] Furthermore, the holder 1231 may have multiple outer surfaces. For example, the holder 1231 may have a first holder outer surface 1231S1, a second holder outer surface 1231S2, a third holder outer surface 1231S3, and a fourth holder outer surface 1231S4.

[0126] The outer surface 1231S1 of the first holder can be positioned to face the outer surface 1231S2 of the second holder. That is, the outer surface 1231S1 of the first holder can be positioned symmetrically with respect to the first direction (X-axis direction) with respect to the outer surface 1231S2 of the second holder.

[0127] The outer surface 1231S1 of the first holder can be positioned to face the side portion 1221 of the first housing. The outer surface 1231S2 of the second holder can be positioned to face the side portion 1222 of the second housing.

[0128] Furthermore, the outer surface 1231S1 of the first holder may include a first mounting groove 1231S1a. The outer surface 1231S2 of the second holder may include a second mounting groove 1231S2a. The first mounting groove 1231S1a and the second mounting groove 1231S2a may be arranged symmetrically with respect to the first direction (X-axis direction).

[0129] Furthermore, the first mounting groove 1231S1a may be used to arrange the first connecting member and the first magnet, which will be described later, and the second connecting member and the second magnet 1251b may be used to arrange the second mounting groove 1231S2a. The first magnet and the second magnet may also be arranged symmetrically with respect to the first direction (X-axis direction). In addition, the first connecting member and the second connecting member may also be arranged symmetrically with respect to the first direction (X-axis direction).

[0130] Furthermore, the first magnet and the second magnet may overlap in the second direction, and the first and second connecting members may overlap in the second direction. As mentioned above, depending on the positions of the first and second mounting grooves and the first and second magnets, the electromagnetic force induced by the magnets may be provided coaxially to the outer surface 1231S1 of the first holder and the outer surface 1231S2 of the second holder. For example, the region applied to the outer surface S1231S1 of the first holder (e.g., the part where the electromagnetic force is strongest) and the region applied to the outer surface S1231S1 of the second holder (e.g., the part where the electromagnetic force is strongest) may be located on an axis parallel to the second direction (Y-axis direction). This allows for accurate X-axis tilting.

[0131] Furthermore, the outer surfaces 1231S1 of the first holder and 1231S2 of the second holder may include additional grooves (not shown). These grooves (not shown) can reduce the weight of the holder 1231, minimizing energy consumption during uniaxial or biaxial tilt. That is, the intensity of the current applied to the first, second, and third coils can be minimized, thereby improving energy efficiency. Additionally, the aforementioned grooves (not shown) may be arranged symmetrically with respect to the first direction (X-axis direction). This prevents the center of gravity of the holder 1231 from concentrating on one side, allowing the tilt to be performed with a uniform force.

[0132] The outer surface 1231S3 of the third holder is in contact with the outer surface 1231S1 of the first holder and the outer surface 1231S2 of the second holder, and may be an outer surface that extends in the second direction (Y-axis direction) between the outer surface 1231S1 of the first holder and the outer surface 1231S2 of the second holder. As a result, the outer surface 1231S3 of the third holder can be located between the outer surface 1231S1 of the first holder and the outer surface 1231S2 of the second holder.

[0133] Furthermore, the outer surface 1231S3 of the third holder can be the bottom surface of the holder 1231. The outer surface 1231S3 of the third holder can be positioned to face the side portion 1223 of the third housing. Furthermore, the outer surface 1231S3 of the third holder can be in contact with the side portion 1223 of the third housing.

[0134] Furthermore, the outer surface 1231S3 of the third holder may include a third mounting groove 1231S3a. A third magnet 1251c may be placed in the third mounting groove 1231S3a. Also, the third housing hole 1223a may overlap with the third mounting groove 1231S3a in the first direction (X-axis direction) at least partially. Accordingly, the third magnet 1251c in the third mounting groove 1231S3a and the third coil 1252c in the third housing hole 1223a can be positioned to face each other. Then, the third magnet 1251c and the third coil 1252c generate an electromagnetic force, enabling the camera actuator to perform Y-axis tilting.

[0135] Furthermore, while X-axis tilt can be achieved by multiple magnets (first and second magnets 1251a and 1251b), Y-axis tilt can be achieved solely by the third magnet 1251c. In one embodiment, the width of the third mounting groove 1231S3a may differ from that of the first mounting groove 1231S1a or the second mounting groove 1231S2a. For example, the width of the third mounting groove 1231S3a may be larger than that of the first mounting groove 1231S1a or the second mounting groove 1231S2a. With such a configuration, Y-axis tilt can be performed using current control similar to that of X-axis tilt.

[0136] The outer surface 1231S3 of the third holder may further include an additional groove 1231S3b. Through such grooves 1231S3b, the weight of the holder 1231 can be reduced, minimizing energy consumption during uniaxial or biaxial tilt. That is, the intensity of the current applied to the first, second, and third coils can be minimized, thereby improving energy efficiency.

[0137] Furthermore, there may be multiple additional grooves 1231S3b on the outer surface 1231S3 of the third holder, and if there are multiple grooves, they may be arranged symmetrically with respect to the first direction (X-axis direction).

[0138] The outer surface 1231S4 of the fourth holder is in contact with the outer surface 1231S1 of the first holder and the outer surface 1231S2 of the second holder, and may be an outer surface extending from the outer surface 1231S3 of the third holder in the first direction (X-axis direction). Furthermore, the outer surface 1231S4 of the fourth holder can be located between the outer surface 1231S1 of the first holder and the outer surface 1231S2 of the second holder.

[0139] Figure 8a is a perspective view of the guide portion according to the embodiment, Figure 8b is a perspective view of the support portion according to the embodiment, Figure 8c is a side view of the support portion according to the embodiment, Figure 8d is a top view of the support portion according to the embodiment, Figure 8e is a perspective view of the first elastic portion according to the embodiment, Figure 8f is a plan view of the first elastic portion according to the embodiment, Figure 8g is a perspective view of the second elastic portion according to the embodiment, Figure 8h is a plan view of the second elastic portion according to the embodiment, Figure 8i is a diagram illustrating the movement of the first elastic portion of the guide portion according to the embodiment, Figure 8j is a diagram illustrating the movement of the second elastic portion of the guide portion according to the embodiment, and Figure 8k is a perspective view of the guide portion according to another embodiment.

[0140] First, referring to Figure 8a, the guide portion 1240 according to the embodiment may include a support portion 1241, a first elastic portion 1242, and a second elastic portion 1243. The first elastic portion 1242 and the second elastic portion 1243 are movable, but this specification will be described with reference to the drawings.

[0141] The support portion 1241 in this embodiment can be connected to the mover and housing through a first elastic portion and a second elastic portion. The support portion 1241 can move with reference to a first direction (X-axis direction). However, the support portion 1241 does not move with reference to a second direction (Y-axis direction). A detailed explanation of this will be given later.

[0142] Furthermore, the first elastic portion 1242 is positioned between the support portion 1241 and the mover, enabling the support portion 1241 and the mover to connect with each other. The first elastic portion 1242 may have a first pattern positioned along a first direction (X-axis direction) and located between the first support portion and the coupling hole. The first elastic portion 1242 can tilt (or move in the second direction) on a second axis with respect to the first pattern.

[0143] Furthermore, the second elastic portion 1243 is positioned between the support portion 1241 and the housing, thereby connecting the support portion 1241 and the housing to each other. The second elastic portion 1243 may have a second pattern positioned along a second direction (Y-axis direction). The second elastic portion 1243 can tilt (or move in the first direction) along the first axis with respect to the second pattern. A more detailed explanation of this will follow later.

[0144] In one embodiment, the first elastic portion 1242 may be arranged perpendicular to the second elastic portion 1243.

[0145] Referring to Figures 8b to 8d, the support portion 1241 in this embodiment can be positioned apart from the mover and housing in a third direction (Z-axis direction). Accordingly, biaxial tilt can be performed at a desired angle through the support portion 1241.

[0146] Furthermore, the support portion 1241 may include a first support portion SA1 extending in a first direction (X-axis direction) and a second support portion SA2 extending in a second direction (Y-axis direction).

[0147] The first support portion SA1 may be extended in the first direction (X-axis direction). For example, the length of the first support portion SA1 in the first direction (X-axis direction) on a plane (XY) may be greater than the length in the second direction (Y-axis direction).

[0148] The second support portion SA2 may be extended in a second direction (Y-axis direction). For example, the length of the second support portion SA2 in the second direction (Y-axis direction) on a plane (XY) may be greater than its length in the first direction (X-axis direction).

[0149] As an example, the length L2 of the first support part SA1 in the second direction (Y-axis direction) may be smaller than the length L1 of the second support part SA2 in the second direction (Y-axis direction).

[0150] The first support portion SA1 may be located above the second support portion SA2, or the second support portion SA2 may be located below the first support portion SA1. The first support portion SA1 may be supported by the second support portion SA2. The first support portion SA1 and the second support portion SA2 according to the embodiment may be joined together. For example, the first support portion SA1 and the second support portion SA2 may be formed integrally.

[0151] The first support part SA1 does not have to coincide with the imaginary line IV1 that bisects the mover or the second support part SA2 in the second direction (Y-axis direction). That is, the first support part SA1 may be positioned at a distance from the imaginary line IV1 in the second direction (Y-axis direction). Alternatively, the first support part SA1 may be positioned offset from the imaginary line IV1 in the second direction (Y-axis direction).

[0152] The first support portion SA1 can contact the upper surface SA2u of the second support portion SA2. The first support portion SA1 may also include a first connecting projection PP1 positioned on one side surface SA1s. At least a portion of the first connecting projection PP1 may overlap with the aforementioned imaginary line IV1 in the third direction (Z-axis direction). With this configuration, the first elastic portion is coupled to the support portion 1241 through the first connecting projection PP1, and the first elastic portion can be rotated.

[0153] The first connecting projection PP1 can be connected to the first elastic portion, which will be described later. In one example, the first connecting projection PP1 can be in contact with one side surface SA1s and the upper surface SA2u of the second support portion SA2.

[0154] The first connecting projection PP1 can be positioned on one side SA1s of the first support portion SA1 in the third direction (Z-axis direction) on the bisector or region. Accordingly, the supporting force on the first elastic portion by the first connecting projection PP1 can be applied uniformly to the support portion, that is, the phenomenon of supporting force concentrating on one side of the support portion can be prevented.

[0155] As described above, the second support part SA2 can be connected to the first support part SA1 and the first connecting projection PP1 at its upper surface SA2u.

[0156] Furthermore, the second support portion SA2 may include a second connecting projection PP2 positioned on its lower surface SA2b. The second connecting projection PP2 may protrude downward from the lower surface SA2b of the second support portion SA2. The second connecting projection PP2 can then connect to a connecting hole in the second elastic portion, which will be described later. Accordingly, the second elastic portion is positioned below the support portion 1241 and the mover, allowing it to easily support the support portion 1241 and the mover.

[0157] Furthermore, there may be at least one second connecting projection PP2. The second connecting projection PP2 may be arranged symmetrically with respect to the first direction (X-axis direction). With this configuration, the second elastic portion prevents the bonding force between the support portion 1241 and the mover from concentrating on one side of the second support portion SA2.

[0158] Furthermore, the second connecting projection PP2 can be centrally located in the third direction (Z-axis direction) on the second support portion SA2. With this configuration, force can be applied uniformly to the support portion 1241 through the second connecting projection PP2.

[0159] Furthermore, according to the embodiment, the first elastic portion 1242 can be coupled to one side of the support portion, particularly to one side SA1s of the first support portion, as described above. In addition, the first elastic portion can be coupled to the lower side of the mover.

[0160] Furthermore, the second elastic portion 1243 can be coupled to the lower surface of the support portion, particularly the lower surface SA2b of the second support portion SA2. In addition, the second elastic portion 1243 can be coupled to the housing.

[0161] Furthermore, one side surface SA1s of the first support and the lower surface SA2b of the second support SA2 can be perpendicular to each other. This allows the first and second elastic parts to tilt relative to directions perpendicular to each other, and ultimately the mover can also be tilted on two axes.

[0162] Referring to Figures 8e to 8f, the first elastic portion 1242 according to the embodiment can be coupled to the first support portion SA1 as described above. The length of the first elastic portion 1242 in the first direction (X-axis direction) may be greater than the length in the second direction (Y-axis direction). Also, the first elastic portion 1242 may overlap at least partially with the aforementioned imaginary line (see Figure 8c, IV1). As a result, the first elastic portion 1242 can rotate or move with respect to the first direction (X-axis direction) or the imaginary line, with respect to the 1-1 coupling region 1242b described later. Accordingly, the support portion, the second elastic portion, and the mover connected to the first elastic portion 1242 can move in accordance with the movement of the 1-1 coupling region 1242b.

[0163] First, the first elastic portion 1242 may include a first pattern PT1 arranged along a first direction (X-axis direction). The first pattern PT1 may be a groove or a hole. Hereinafter, it will be described as a hole as shown in the drawing. Such first patterns PT1 may be arranged side by side in the first direction (X-axis direction). In other words, multiple holes may be arranged side by side along the first direction (X-axis direction).

[0164] The first pattern PT1 can be arranged symmetrically with respect to the second direction (Y-axis direction). This can improve the reliability of the first elastic part 1242 even when rotating through the first pattern PT1.

[0165] The first elastic portion 1242 may consist of a first pattern region 1242a, a 1-1 bonding region 1242b, and a 1-2 bonding region 1242c along the third direction (Z-axis direction).

[0166] The first pattern region 1242a may be the region where the first pattern PT1 is placed. The first pattern region 1242a may be a region that extends in the first direction (X-axis direction) corresponding to the first pattern PT1.

[0167] Furthermore, the first-to-first bonding region 1242b and the first-to-second bonding region 1242c can be demarcated by the first pattern region 1242a.

[0168] The first-to-first bonding region 1242b can be located between the first pattern region 1242a and the mover. Alternatively, the first-to-first bonding region 1242b can be bonded to the first support.

[0169] The first-to-second bonding region 1242c can be located between the first pattern region 1242a and the housing (e.g., the fourth housing side). Alternatively, the first-to-second bonding region 1242c can be located within the bonding hole of the fourth housing side.

[0170] Because the first pattern region 1242a has the first pattern PT1, its relative stiffness to the first-to-first bonding region 1242b and the first-to-second bonding region 1242c may be small. As a result, the first-to-first bonding region 1242b and the first-to-second bonding region 1242c can be folded relative to the first pattern region 1242a. In other words, the first-to-first bonding region 1242b and the first-to-second bonding region 1242c can move.

[0171] Furthermore, in the first pattern region 1242a, the holes that are the first pattern PT1 are arranged along the first direction (X-axis direction), and the 1-1 bonding region 1242b and the 1-2 bonding region 1242c can rotate with respect to the first direction (X-axis direction).

[0172] The first-first bonding region 1242b can be bonded to the first support. The first-first bonding region 1242b may include a first-first elastic hole 1242h1 and a first-first elastic groove 1242p1.

[0173] The first-first elastic hole 1242h1 can be positioned at a distance from the first-first elastic groove 1242p1 in the first-first bonding region 1242b. An adhesive can be applied to the first-first elastic hole 1242h1. The first-first bonding region 1242b can then be bonded to the support by the adhesive.

[0174] Furthermore, the first-first elastic groove 1242p1 can be located below the first-first coupling region 1242b. This allows the lower part of the first-first coupling region 1242b to be opened by the first-first elastic groove 1242p1. Consequently, the manufacturing of the first-first coupling region 1242b becomes easier, and the coupling between the first-first coupling region 1242b and the support can be easily achieved. For example, the coupling between the first-first coupling region 1242b and the support can be achieved by insertion. In addition, the coupling force of the element can be improved by applying a load to the lower part.

[0175] The adhesive material can be applied to the first elastic groove 1242p1.

[0176] The first-to-second bonding region 1242c can be coupled to the protrusion of the bonding hole on the side of the fourth housing. The first-to-second bonding region 1242c may include the first-to-second elastic hole 1242h2 and the first-to-second elastic groove 1242p2.

[0177] The first-to-second elastic holes 1242h2 can be spaced apart from the first-to-second elastic grooves 1242p2 in the first-to-second bonding region 1242c. An adhesive can be applied to the first-to-second elastic holes 1242h2. The adhesive can then bond the first-to-second bonding region 1242c to the fourth housing side.

[0178] Furthermore, the first-to-second elastic groove 1242p2 can be located below the first-to-second bonding region 1242c. This allows the lower part of the first-to-second bonding region 1242c to be open due to the first-to-second elastic groove 1242p2. Consequently, the manufacturing of the first-to-second bonding region 1242c becomes easier, and the bonding between the first-to-second bonding region 1242c and the support portion can be facilitated. For example, the bonding between the first-to-second bonding region 1242c and the support portion can be achieved by insertion. Furthermore, the bonding force of the element can be improved by applying a load to the lower part. In addition, an adhesive member can be applied to the first-to-second elastic groove 1242p2.

[0179] Referring to Figures 8g to 8h, the second elastic portion 1243 according to the embodiment can be connected to the second support portion SA2 as described above. The length of the second elastic portion 1243 in the second direction (Y-axis direction) may be greater than the length in the first direction (X-axis direction).

[0180] The second elastic portion 1243 can be bisected by the aforementioned imaginary line (see Figure 8c, IV1). In other words, the line of bisector in the second direction (Y-axis direction) of the second elastic portion 1243 can correspond to the aforementioned imaginary line.

[0181] Furthermore, the second elastic portion 1243 can rotate or move with respect to the second direction (Y-axis direction) of the second-first bonding region 1243b, which will be described later. Accordingly, the mover connected to the second elastic portion 1243 can move in accordance with the movement of the second-second bonding region 1243c.

[0182] First, the second elastic portion 1243 may include a second pattern PT2 arranged along the second direction (Y-axis direction). The second pattern PT2 may be a groove or a hole. Hereinafter, it will be described as a hole as shown in the drawing. Such second patterns PT2 may be arranged side by side in the second direction (Y-axis direction). In other words, multiple holes may be arranged side by side along the second direction (Y-axis direction). Such second patterns PT2 may be located between the lower surface of the mover and the second support portion.

[0183] The second pattern PT2 can be arranged symmetrically with respect to the first direction (X-axis direction). This ensures that the load applied to the second elastic part 1243 is uniform during rotation through the second pattern PT2, thereby improving the reliability of the second elastic part 1243.

[0184] The second elastic portion 1243 may consist of a second pattern region 1243a, a 2-1 bonding region 1243b, and a 2-2 bonding region 1243c along the third direction (Z-axis direction).

[0185] The second pattern region 1243a may be the region where the second pattern PT2 is placed. The second pattern region 1243a may be a region that extends in the second direction (Y-axis direction) corresponding to the second pattern PT2.

[0186] Furthermore, the second-first bonding region 1243b and the second-second bonding region 1243c may be demarcated by the second pattern region 1243a. First, the second-first bonding region 1243b can be located between the second pattern region 1243a and the fourth housing side. Alternatively, the second-first bonding region 1243b can be bonded to the second support.

[0187] The second-to-second bonding region 1243c can be located between the second pattern region 1243a and the mover. Alternatively, the second-to-second bonding region 1243c can be located between the fifth housing sides.

[0188] The second pattern region 1243a may have a smaller relative stiffness to the second-first bond region 1243b and the second-second bond region 1243c because it has the second pattern PT2. As a result, the second-first bond region 1243b and the second-second bond region 1243c can be folded relative to the first pattern region 1243a. In other words, the second-first bond region 1243b and the second-second bond region 1243c can move.

[0189] Furthermore, in the second pattern region 1243a, the holes of the second pattern PT2 are arranged along the first direction (X-axis direction), allowing the second-first bonding region 1243b and the second-second bonding region 1243c to rotate with respect to the second direction (Y-axis direction).

[0190] The second-first bonding region 1243b can be bonded to the second support. The second-first bonding region 1243b may contain the second-first elastic hole 1243h1.

[0191] The second-first elastic hole 1243h1 can be connected to the second connecting projection PP2 described above. That is, the second-first elastic hole 1243h1 can be positioned corresponding to the second connecting projection PP2. As a result, the second-first elastic hole 1243h1 can be positioned symmetrically with respect to the first direction (X-axis direction) or the third direction (Z-axis direction). An adhesive member can be applied to the second-first elastic hole 1243h1. Then, the second-first connecting region 1243b can be connected to the second support portion by the adhesive member.

[0192] The second-second bonding region 1243c can bond to the lower surface of the mover. The second-second bonding region 1243c can contain the second-second elastic hole 1243h2, the second-third elastic hole 1243h3, and the second-fourth elastic hole 1243h4.

[0193] The second-second elastic hole 1243h2 can be coupled to the lower mover projection of the mover at the second-second bonding region 1243c. An adhesive can be applied to the second-second elastic hole 1243h2, and the second-second bonding region 1243c can then be coupled to the mover by the adhesive.

[0194] The second and third elastic holes 1243h3 can be positioned corresponding to the third mounting groove at the bottom of the mover. Alternatively, the second and third elastic holes 1243h3 can be positioned corresponding to the third magnet mounted in the third mounting groove. This configuration prevents a reduction in the electromagnetic force generated between the third magnet and the third coil.

[0195] Furthermore, the second-to-fourth elastic holes 1243h4 reduce the weight of the second elastic section 1243 and reduce the influence of the first and second magnets positioned in the first and second mounting grooves. In other words, the generation of magnetic force between the second elastic section 1243 and the first or second magnet can be prevented through the second-to-fourth elastic holes 1243h4. This allows for more accurate and efficient two-axis tilting.

[0196] Furthermore, the length L4 of the second-first bonding region 1243b in the third direction (Z-axis direction) may be smaller than the length L3 of the second-second bonding region 1243c in the third direction (Z-axis direction). Accordingly, the second elastic portion 1243 can easily support the load of the mover through the second-second bonding region 1243c.

[0197] Referring to Figure 8i, as mentioned above, since the second pattern region 1243a of the second elastic portion 1243 has lower rigidity compared to the other regions 1243b and 1243c, the first axial tilt can be performed with respect to the second pattern region 1243a. That is, the second-second coupling region 1243c of the second elastic portion 1243 is tilted by the first axis, and the mover positioned on the second-second coupling region 1243c can also be tilted by the first axis.

[0198] Referring to Figure 8j, as mentioned above, since the first pattern region 1242a of the first elastic portion 1242 has lower relative stiffness to the other regions 1242b and 1242c, a second axial tilt can be performed with respect to the first pattern region 1242a. That is, the 1-1 coupling region 1242b of the first elastic portion 1242 is tilted by the second axis, and the mover positioned on the 1-1 coupling region 1242b can also be tilted by the second axis.

[0199] Referring to Figure 8k, in the support portion 1241' of the guide portion 1240 according to other embodiments, there may be multiple first support portions SA1a and SA1b. That is, there are multiple first support portions SA1a and SA1b, and they may be arranged to face each other with respect to the aforementioned imaginary line.

[0200] Consequently, the bonding force between the first elastic portion 1242 and the first support portions SA1a and SA1b can be improved. As a result, even if the first elastic portion 1242 tilts more components than the second elastic portion 1243, it can easily perform biaxial tilt.

[0201] Figure 9 is a diagram illustrating the drive unit according to an embodiment.

[0202] Referring to Figure 9, as mentioned above, the drive unit 1250 includes a drive magnet 1251, a drive coil 1252, a Hall sensor unit 1253, a coupling unit 1254, and a substrate unit 1255.

[0203] Furthermore, as mentioned above, the drive magnet 1251 may include a first magnet 1251a, a second magnet 1251b, and a third magnet 1251c that provide driving force by electromagnetic force. The first magnet 1251a, the second magnet 1251b, and the third magnet 1251c can each be located on the outer surface of the holder 1231.

[0204] Furthermore, the drive coil 1252 may include multiple coils. For example, the drive coil 1252 may include a first coil 1252a, a second coil 1252b, and a third coil 1252c.

[0205] The first coil 1252a can be positioned opposite the first magnet 1251a. This allows the first coil 1252a to be located in the first housing hole 1221a of the first housing side 1221, as described above. The second coil 1252b can be positioned opposite the second magnet 1251b. This allows the second coil 1252b to be located in the second housing hole 1222a of the second housing side 1222, as described above.

[0206] The second camera actuator according to this embodiment controls the rotation of the mover 1230 in a first direction (X-axis direction) or a second direction (Y-axis direction) by the electromagnetic force between the drive magnet 1251 and the drive coil 1252, thereby minimizing the occurrence of descent and tilt phenomena when OIS is implemented and providing the best possible optical characteristics.

[0207] Furthermore, according to the embodiment, by realizing OIS through the guide portion 1240 of the guide portion positioned between the housing 1220 and the mover 1230, the size limitations of the actuator can be overcome, and an ultra-slim, ultra-compact camera actuator and a camera module including the same can be provided.

[0208] The connecting portion 1254 may include a first connecting member 1254a, a second connecting member 1254b, and a third connecting member 1254c.

[0209] Furthermore, the first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c can each be positioned between the first magnet 1251a to the third magnet 1251c and the holder 1231.

[0210] The first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c can be yokes. Accordingly, the first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c can each be connected to the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c, respectively.

[0211] Furthermore, the first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c are each positioned within the first mounting groove, the second mounting groove, and the third mounting groove, and can be easily bonded to the first mounting groove, the second mounting groove, and the third mounting groove through adhesive members injected through grooves formed in the first mounting groove, the second mounting groove, and the third mounting groove.

[0212] The substrate portion 1255 may include a first substrate side portion 1255a, a second substrate side portion 1255b, and a third substrate side portion 1255c.

[0213] The first substrate side portion 1255a and the second substrate side portion 1255b may be arranged to face each other. The third substrate side portion 1255c may be located between the first substrate side portion 1255a and the second substrate side portion 1255b.

[0214] Furthermore, the first substrate side portion 1255a can be located between the first housing side portion and the shield can, and the second substrate side portion 1255b can be located between the second housing side portion and the shield can. Also, the third substrate side portion 1255c can be located between the third housing side portion and the shield can, and may be the bottom surface of the substrate portion 1255.

[0215] The first substrate side portion 1255a can be coupled to the first coil 1252a and electrically connected. Furthermore, the first substrate side portion 1255a can be coupled to the first Hall sensor 1253a and electrically connected.

[0216] The second substrate side portion 1255b may be electrically connected by coupling with the second coil 1252b. It should also be understood that the second substrate side portion 1255b may be electrically connected by coupling with the second Hall sensor 1253b.

[0217] Furthermore, the first substrate side portion 1255a and the second substrate side portion 1255b can be extended in a third direction (Z-axis direction). This allows the first substrate side portion 1255a and the second substrate side portion 1255b to have regions that extend from the fifth housing side portion in the third direction (Z-axis direction).

[0218] Furthermore, the third substrate side portion 1255c can be electrically connected by coupling with the third coil 1252c. Also, the third substrate side portion 1255c can be electrically connected by coupling with the third Hall sensor 1253c.

[0219] Figure 10 is a perspective view of the second camera actuator in an embodiment in which the shield can and substrate have been removed, Figure 11a is a cross-sectional view taken at BB' in Figure 10, Figure 11b is a cross-sectional view taken at CC' in Figure 10, and Figure 11c is a cross-sectional view taken at DD' in Figure 10.

[0220] Referring to Figures 10 and 11a to 11c, the first coil 1252a can be located on the first housing side 1221, and the first magnet 1251a and the first coupling member 1254a can be located on the first holder outer surface 1231S1 of the holder 1231.

[0221] Furthermore, the first coil 1252a and the first magnet 1251a can be positioned facing each other. The first magnet 1251a can overlap the first coil 1252a in the second direction (Y-axis direction) at least partially. Also, the first connecting member 1254a can overlap the first coil 1252a in the second direction (Y-axis direction) at least partially.

[0222] Furthermore, the second coil 1252b can be located on the side portion 1222 of the second housing, and the second magnet 1251b and the second coupling member 1254b can be located on the outer surface 1231S2 of the second holder 1231. This allows the second coil 1252b and the second magnet 1251b to be positioned opposite each other. The second magnet 1251b can overlap the second coil 1252b in the second direction (Y-axis direction) at least partially. Also, the second coupling member 1254b can overlap the second coil 1252b in the second direction (Y-axis direction) at least partially.

[0223] Furthermore, the first coil 1252a and the second coil 1252b may overlap in the second direction (Y-axis direction), and the first magnet 1251a and the second magnet 1251b may overlap in the second direction (Y-axis direction). With this configuration, the electromagnetic force applied to the outer surfaces of the holder (outer surface of the first holder and outer surface of the second holder) is located on an axis parallel to the second direction (Y-axis direction), allowing for accurate and precise X-axis tilt.

[0224] Furthermore, as described above, the first Hall sensor 1253a and the second Hall sensor 1253b can be located on the outside for electrical connection and coupling with the substrate portion 1255. However, they are not limited to such positions.

[0225] Furthermore, the third coil 1252c can be located on the side portion 1223 of the third housing, and the third magnet 1251c can be located on the outer surface 1231S3 of the holder 1231. The third coil 1252c and the third magnet 1251c can overlap at least partially in the first direction (X-axis direction). Accordingly, the strength of the electromagnetic force between the third coil 1252c and the third magnet 1251c can be easily controlled.

[0226] As described above, the guide portion 1240 can be positioned between the holder 1231 and the fourth housing side portion 1224.

[0227] Furthermore, the first elastic portion 1242 can be positioned so as to overlap at least partially with a line that bisects the mover 1230 in the second direction (Y-axis direction). In other words, the first elastic portion 1242 can be located in the center of the holder 1231 of the mover 1230.

[0228] As a result, the support portion connected to the 1-1 connecting region can move in the second direction (Y-axis direction) or tilt along the first axis, with reference to the first pattern region where the first pattern PT1 is located in the first elastic portion 1242.

[0229] In the guide portion 1240, the first elastic portion 1242 can connect with the protrusion CHP located on one surface of the coupling hole CH of the housing 1220. In the first elastic portion 1242, the first-first elastic groove 1242p1 located in the first-second coupling region and the protrusion CHP can connect with each other.

[0230] Furthermore, the first-second elastic groove 1242p2 located in the first-first bonding region can be connected to the first bonding projection PP1 of the support portion 1241. This allows the housing 1220, the first elastic portion 1242, and the support portion 1241 to be connected to each other. In addition, the support portion 1241 can be connected to the second bonding projection PP2 of the support portion 1241 through the second elastic portion 1243. The second elastic portion 1243 can then be connected to the mover projection of the mover through the second-second bonding region. As a result, the housing 1220, the guide portion 1240, and the mover 1230 are all connected, and the mover can be tilted biaxially by the first elastic portion 1241 and the second elastic portion 1242.

[0231] Furthermore, the lower surfaces of the first-first elastic groove 1242p1 and the first-second elastic groove 1242p2 can be the same plane.

[0232] Furthermore, the first-to-second elastic hole 1242h2 and the first-to-first elastic hole 1242h1 can be aligned in the third direction (Z-axis direction). This can further improve the bonding force. Figure 12 is an illustrative diagram of the movement of the second camera actuator shown in Figure 11a, and Figure 13 is an illustrative diagram of the movement of the second camera actuator shown in Figures 11b and 11c.

[0233] Referring to Figure 12, Y-axis tilt can be performed. That is, OIS can be realized by rotating in the first direction (X-axis direction).

[0234] In one embodiment, the third magnet 1251c, positioned at the bottom of the holder 1231, forms an electromagnetic force with the third coil 1252c, causing the mover 1230 to tilt or rotate in the first direction (X-axis direction). That is, the aforementioned electromagnetic force allows the holder 1231 and the holder 1231 and the second elastic part 1243 to move in the first direction (X-axis direction).

[0235] More specifically, the 2-2 bonding region of the second elastic portion 1243 and the mover 1230 can rotate in the first direction (X-axis direction) with respect to the second pattern region.

[0236] In other words, the mover 1230 can rotate or tilt using the second pattern or the second pattern region as the reference axis (or axis of rotation).

[0237] For example, OIS implementation can be achieved by first electromagnetic forces F1A and F1B between the third magnet 1251c positioned in the third mounting groove and the third coil 1252c positioned on the side of the third substrate, causing the mover 1230 to rotate in the X-axis direction by a first angle θ1 (X1->X1a or X1->X1b). The first angle θ1 may be ±1° to ±3°, but is not limited to this.

[0238] Referring to Figure 13, an X-axis tilt can be performed. That is, rotation in the second direction (Y-axis direction) can be used to realize OIS.

[0239] OIS implementation can be achieved while the mover 1230 tilts or rotates in the Y-axis direction (or tilts along the X-axis).

[0240] In one embodiment, the first magnet 1251a and the second magnet 1251b, positioned on the holder 1231, each form an electromagnetic force with the first coil 1252a and the second coil 1252b, respectively, causing the guide portion 1240 and the mover 1230 to tilt or rotate in the second direction (Y-axis direction). That is, the aforementioned electromagnetic force allows the holder 1231 and the guide portion 1240 coupled to the holder 1231 to rotate or move in the second direction (Y-axis direction).

[0241] Specifically, the first-to-first coupling region of the first elastic portion 1242, the support portion 1241, the second elastic portion 1243, and the mover 1231 of the guide portion 1240 can rotate or tilt (X-axis tilt) in a second direction with the first pattern or first pattern region of the first elastic portion 1242 as the reference axis (or rotation axis).

[0242] For example, the second electromagnetic forces F2A and F2B between the first and second magnets 1251a and 1251b positioned in the first mounting groove and the first and second coil sections 1252a and 1252b positioned on the sides of the first and second substrates can cause the mover 1230 to rotate by a second angle θ2 in the Y-axis direction (Y1->Y1a or Y1->Y1b) while OIS is realized. The second angle θ2 can be ±1° to ±3°, but is not limited to this.

[0243] Thus, the second camera actuator according to this embodiment minimizes the occurrence of descent and tilt phenomena when OIS is implemented and provides the best optical characteristics by controlling the rotation of the guide section 1240 and mover 1230 in a first direction (X-axis direction) or a second direction (Y-axis direction) by the electromagnetic force between the drive magnet in the holder and the drive coil arranged in the housing. Furthermore, as mentioned above, "Y-axis tilt" corresponds to rotation or tilt in the first direction (X-axis direction), and "X-axis tilt" corresponds to rotation or tilt in the second direction (Y-axis direction).

[0244] FIG. 14 is a perspective view of a second camera actuator according to another embodiment, and FIG. 15 is an exploded perspective view of the second camera actuator according to another embodiment.

[0245] Referring to FIGS. 14 and 15, the second camera actuator 1200 according to the embodiment includes a shield can 1210, a housing 1220, a mover 1230, a rotating plate 1240, and a driving unit 1250. It should be understood that the components are not assembled along the lines (e.g., two-dot chain lines) shown in this exploded perspective view. The shield can 1210, housing 1220, mover 1230, and driving unit 1250 described above for the second camera actuator 1200 according to another embodiment correspond to the shield can 1210, housing 1220, mover 1230, and driving unit 1250 to be described later, and the foregoing content may be applicable. Further, although the rotating plate 1240 to be described later is different from the guide unit 1240 that performs X-axis tilt and Y-axis tilt, the tilt driving can be performed identically. Further, other components can be applied identically in the embodiment and other embodiments except for the configuration coupled to the rotating plate and the guide unit.

[0246] First, the mover 1230 includes a holder 1231, an optical member 1232 mounted on the holder 1231, and a plate cover 1233 that covers the optical member 1232 and the rotating plate 1240 and is coupled to the holder 1231. The rotating plate 1240 is positioned between the holder 1231 and the plate cover 1233 and can be coupled to the mover 1230 and the housing 1220. And the rotating plate 1240 can perform tilts with respect to two axes. As an example, the rotating plate 1240 can rotate in the first direction (X-axis direction) (corresponding to the second-axis tilt). Also, the rotating plate 1240 can rotate in the second direction (Y-axis direction) (corresponding to the first-axis tilt). Also, the driving unit 1250 includes a driving magnet 1251, a driving coil 1252, a hall sensor unit 1253, a coupling unit 1254, and a substrate unit 1255. Each component will be described below.

[0247] The shield can 1210 can be located in an area (e.g., the outermost side) of the second camera actuator 1200 and can be positioned to surround the rotation plate 1240 and the drive unit 1250 described later.

[0248] Such a shield can 1210 can block or reduce electromagnetic waves generated externally. Accordingly, the occurrence of malfunction in the rotation plate 1240 or the drive unit 1250 can be reduced.

[0249] The housing 1220 can be located inside the shield can 1210. Also, the housing 1220 can be located inside the substrate portion 1255. The housing 1220 and the shield can 1210 can be inserted into or aligned with each other and fastened.

[0250] The housing 1220 can include a plurality of housing side portions. As an example, the housing 1220 can include a first housing side portion to a fifth housing side portion. A detailed description thereof will be given later.

[0251] The housing 1220 can include a housing portion 1226 which is a cavity between a plurality of housing side portions.

[0252] The mover 1230 includes a holder 1231 and an optical member 1232 attached to the holder 1231.

[0253] The holder 1231 can be attached to the housing portion 1226 of the housing 1220. The holder 1231 can include a first holder outer surface to a fourth holder outer surface corresponding to the first housing side portion, the second housing side portion, the third housing side portion, and the fourth housing side portion, respectively. A detailed description thereof will be given later.

[0254] The optical element 1232 can be mounted on the holder 1231. For this purpose, the holder 1231 may have a mounting portion, which may be formed by a housing portion. The optical element 1232 may include, but is not limited to, a reflective portion located inside. The optical element 1232 can reflect light reflected from the outside (e.g., an object) into the camera module. In other words, the optical element 1232 can improve the spatial limitations of the first and second camera actuators by altering the path of the reflected light. It should be understood that this also allows the camera module to provide a wide range of magnification by extending the light path while minimizing its thickness.

[0255] Such optical components 1232 may consist of a prism or mirror, which comprises at least one lens.

[0256] The rotating plate 1240 can be positioned inside the mover 1230. The rotating plate 1240 can be connected to the mover 1230 by being surrounded by the plate cover 1233 and holder 1231 of the mover 1230. The rotating plate 1240 can also be connected to the housing 1220 through a second projection.

[0257] The rotating plate 1240 may include first projections extending upward and downward from the base (e.g., the third housing side and the shield can) and second projections extending toward the housing (e.g., the first housing side and the second housing side). The first and second projections enable the mover 1230 to perform first and second axis tilts. A more detailed explanation of this will follow later.

[0258] The drive unit 1250 includes a drive magnet 1251, a drive coil 1252, a Hall sensor unit 1253, a coupling unit 1254, and a substrate unit 1255.

[0259] The drive magnet 1251 can include multiple magnets. In one embodiment, the drive magnet 1251 can include a first magnet 1251a, a second magnet 1251b, and a third magnet 1251c.

[0260] The first magnet 1251a, the second magnet 1251b, and the third magnet 1251c can each be positioned on the outer surface of the holder 1231. The first magnet 1251a and the second magnet 1251b can be positioned facing each other. The third magnet 1251c can be positioned on the bottom surface of the outer surface of the holder 1231. A more detailed explanation of this will follow later.

[0261] The drive coil 1252 may include multiple coils. For example, the drive coil 1252 may include a first coil 1252a, a second coil 1252b, and a third coil 1252c.

[0262] The first coil 1252a can be positioned opposite the first magnet 1251a. This allows the first coil 1252a to be positioned in the first housing hole 1221a of the first housing side portion 1221, as described above.

[0263] Furthermore, the second coil 1252b can be positioned opposite the second magnet 1251b. This allows the second coil 1252b to be located in the second housing hole 1222a of the second housing side portion 1222, as described above.

[0264] The first coil 1252a can be positioned opposite the second coil 1252b. That is, the first coil 1252a can be positioned symmetrically with respect to the first direction relative to the second coil 1252b. This can also be applied equally to the first magnet 1251a and the second magnet 1251b. With such a configuration, the electromagnetic force between the first coil 1252a and the first magnet 1251a and the electromagnetic force between the second coil 1252b and the second magnet 1251b can accurately cause X-axis tilting without tilting to one side.

[0265] The third coil 1252c can be positioned opposite the third magnet 1251c. This allows the second coil 1252c to be positioned in the third housing hole 1223a of the third housing side 1223, as described above. The third coil 1252c generates an electromagnetic force with the third magnet 1251c, enabling the mover 1230 and the rotating plate 1240 to perform Y-axis tilting relative to the housing 1220.

[0266] Here, X-axis tilting means tilting with the X-axis as the reference (or reference axis), and Y-axis tilting means tilting with the Y-axis as the reference (or reference axis). The first direction is the X-axis direction in the drawing and can be used interchangeably with the second axis direction, second axis, etc. The second direction is the Y-axis direction in the drawing and can be used interchangeably with the first axis direction, first axis, etc. The second direction is perpendicular to the first direction. The third direction is the Z-axis direction in the drawing and can be used interchangeably with the third axis direction, etc. The third direction is perpendicular to both the first and second directions. In this invention, the first direction (X-axis direction) corresponds to the direction of the optical axis with respect to the light incident on the second camera actuator, and the second direction (Y-axis direction) and the third direction (Z-axis direction) are perpendicular to the optical axis and can be tilted by the second camera actuator. Such a third direction can correspond to the direction toward the optical member or holder by the rotating plate. Furthermore, the bottom surface refers to one side in the first direction, and in the housing, the third housing side may be the bottom surface, with the inside being the direction toward the center of the camera actuator and the outside being the opposite direction. This specification should be understood based on the above. However, it should be understood that the optical axis can be changed to the Z axis within the first camera actuator, which will be described later.

[0267] The Hall sensor unit 1253 can include multiple Hall sensors. In one embodiment, the Hall sensor unit 1253 can include a first Hall sensor 1253a, a second Hall sensor 1253b, and a third Hall sensor 1253c. The first Hall sensor 1253a and the second Hall sensor 1253b can be located inside the first coil 1252a or the second coil 1252b. The first Hall sensor 1253a and the second Hall sensor 1253b can sense changes in magnetic flux inside the first coil 1252a or the second coil 1252b. This enables position sensing between the first and second magnets 1251a and 1251b and the first Hall sensor 1253a and the second Hall sensor 1253b. The camera actuator according to this embodiment can control X-axis tilt through this.

[0268] Also, the third Hall sensor 1253c can be located inside the third coil 1252c. The third Hall sensor 1253c can sense the change in magnetic flux inside the third coil 1252c. Thereby, position sensing between the third magnet 1251c and the third Hall sensor 1253c can be performed. The camera actuator according to the embodiment can control the Y-axis tilt through this.

[0269] The coupling portion 1254 can include a first coupling member 1254a, a second coupling member 1254b, and a third coupling member 1254c.

[0270] The first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be respectively located in mounting grooves formed on the outer surface of the holder 1231. And the first coupling member 1254a and the second coupling member 1254b can be positioned to face each other. Also, the third coupling member 1254c can be located on the bottom surface (e.g., the outer surface of the third holder) of the outer surface of the holder 1231.

[0271] Also, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be respectively located between the first magnet 1251a to the third magnet 1251c and the holder 1231.

[0272] The first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be yokes. Accordingly, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be respectively coupled to the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c.

[0273] Furthermore, the first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c are each positioned within the first mounting groove, second mounting groove, and third mounting groove of the holder 1231, and can be easily bonded to the first mounting groove, second mounting groove, and third mounting groove through adhesive members injected through grooves formed in the first mounting groove, second mounting groove, and third mounting groove.

[0274] As a result, the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c can be easily connected to the holder 1231 by the first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c.

[0275] The first magnet 1251a, the second magnet 1251b, and the third magnet 1251c can each be positioned on the outer surface of the holder 1231. The first magnet 1251a and the second magnet 1251b can be positioned facing each other. The third magnet 1251c can be positioned on the bottom surface of the outer surface of the holder 1231. A more detailed explanation of this will follow later.

[0276] The substrate portion 1255 can be located below the drive unit 1250. The substrate portion 1255 can be electrically connected to the drive coil 1252 and the Hall sensor portion 1253. For example, the substrate portion 1255 can be connected to the drive coil 1252 and the Hall sensor portion 1253 and the SMT. However, it is not limited to this configuration.

[0277] The substrate portion 1255 is located between the shield can 1210 and the housing 1220, and can be coupled to the shield can 1210 and the housing 1220. As described above, various coupling methods are possible. Through the aforementioned coupling, the drive coil 1252 and the Hall sensor portion 1253 can be positioned within the outer surface of the housing 1220.

[0278] Such a substrate portion 1255 may include circuit boards with electrically connectable wiring patterns, such as rigid PCBs, flexible PCBs, and rigid-flexible PCBs. However, it is not limited to these types.

[0279] Figure 16a is a perspective view of a housing according to another embodiment, Figure 16b is a side view of the housing as seen from KD in Figure 16a, Figure 16c is a side view of the fifth housing side, Figure 16d is a side view of the first and second housing sides, Figure 16e is a top view of a housing according to another embodiment, Figure 16f is a bottom view of a housing according to another embodiment, Figure 16g is a perspective view of the fourth housing side, and Figure 16h is a drawing illustrating the inner surface of the fourth housing side.

[0280] Referring to Figures 16a to 16i, the housing 1220 may include a first housing side 1221, a second housing side 1222, a third housing side 1223, a fourth housing side 1224, and a fifth housing side 1225.

[0281] The first housing side 1221 and the second housing side 1222 may be positioned opposite each other. The third housing side 1223 may be positioned on the bottom surface of the housing 1220. The fourth housing side 1224 and the fifth housing side 1225 may be positioned opposite each other and located between the first housing side 1221 and the second housing side 1222.

[0282] The third housing side portion 1223 can be in contact with the first housing side portion 1221, the second housing side portion 1222, the fourth housing side portion 1224, and the fifth housing side portion 1225.

[0283] The first housing side portion 1221 may include a first housing hole 1221a. A first coil, described later, can be located in the first housing hole 1221a.

[0284] The first housing side portion 1221 may include a first coupling projection (not shown). Through the first coupling projection (not shown), the first housing side portion 1221 can be easily coupled to the substrate portion.

[0285] Furthermore, the first housing side portion 1221 may include a first mounting projection 1221c. The first mounting projection 1221c may be located on the upper or lower part of the first housing side portion 1221. The first mounting projection 1221c can easily support the substrate portion. This may improve the bonding force between the first housing side portion and the substrate portion.

[0286] Furthermore, the first housing side portion 1221 and the second housing side portion 1222 can include a second projection accommodating groove G2 formed on the side so as to bulge inward or in a third direction. The second projection accommodating groove G2 includes a 2-1 projection accommodating groove G2a and a 2-2 projection accommodating groove G2b, which will be described below based on these. First, the first housing side portion 1221 can include a 2-1 projection accommodating groove G2a formed on the side so as to be inward.

[0287] The second-first projection accommodating groove G2a may be positioned on the surface where the first housing side portion 1221 is in contact with the fourth housing side portion 1224. The second-first projection accommodating groove G2a may be positioned in correspondence with the first-first projection accommodating groove G1a of the fourth housing side portion 1224, which will be described later.

[0288] A second projection, described later, can be fitted between the second-first projection receiving groove G2a and the first-first projection receiving groove G1a. This allows the rotating plate, housing 1220, and mover 1230 to be connected to each other.

[0289] Furthermore, the second housing side portion 1222 may include a second housing hole 1222a. A second coil, which will be described later, can be positioned in the second housing hole 1222a.

[0290] The first housing hole 1221a and the second housing hole 1222a can be positioned opposite each other. For example, the first housing hole 1221a and the second housing hole 1222a can be arranged symmetrically with respect to a first direction (X-axis direction) or a third direction (Z-axis direction). The first coil and the second coil can be electrically connected and coupled to a substrate located outside the housing 1220 through the first housing hole 1221a and the second housing hole 1222a. The first coil and the second coil can be electrically connected to the substrate and current can flow. Such current is an element of electromagnetic force that allows the second camera actuator to tilt with respect to the X-axis.

[0291] The second housing side portion 1222 may include a second coupling projection (not shown). The second housing side portion 1222 can be easily coupled to the substrate portion through the second coupling projection (not shown).

[0292] Furthermore, the second housing side portion 1222 may include a second mounting projection 1222c. The second mounting projection 1222c can be located on the upper or lower part of the second housing side portion 1222. The second mounting projection 1222c can easily support the substrate portion. This may improve the bonding force between the second housing side portion and the substrate portion.

[0293] Furthermore, the second housing side portion 1222 may include a second-second projection accommodating groove G2b formed on the inside of its side surface. The second-second projection accommodating groove G2b may be located on the surface where the second housing side portion 1222 contacts the fourth housing side portion 1224. The second-second projection accommodating groove G2b may be located corresponding to the first-second projection accommodating groove G1b of the fourth housing side portion 1224.

[0294] A second projection, described later, can be fitted between the second-second projection housing groove G2b and the first-second projection housing groove G1b. This allows the rotating plate, housing 1220, and mover 1230 to be connected to each other.

[0295] Furthermore, the third housing side portion 1223 may include a third housing hole 1223a. A third coil, described later, can be located in the third housing hole 1223a. The third coil can be coupled to the substrate portion. In one embodiment, the third coil can be electrically connected to the substrate portion 1255 so that current can flow. Such current is an element of electromagnetic force that allows the second camera actuator to tilt with respect to the Y-axis.

[0296] The third housing side portion 1223 may include a third coupling projection (not shown). Through the third coupling projection (not shown), the third housing side portion 1223 can be easily coupled to the substrate portion.

[0297] The fourth housing side 1224 can be in contact with the first housing side 1221, the second housing side 1222, and the third housing side 1223. In particular, the fourth housing side 1224 may be positioned on the third housing side 1223. The lower surface of the fourth housing side 1224 may be in contact with the upper surface of the third housing side 1223, and the fourth housing side 1224 may be supported by the third housing side 1223. The fourth housing side 1224 may not be positioned in the path of light.

[0298] The fourth housing side portion 1224 may include the first housing base 1224a, the first housing extension 1224b, and the second housing extension 1224c.

[0299] The first housing extension 1224b and the second housing extension 1224c may be extended in a third direction (Z-axis direction) from the first housing base 1224a. In particular, the first housing extension 1224b and the second housing extension 1224c may be extended toward the fifth housing side 1225 from the first housing base 1224a.

[0300] The first housing base 1224a can be positioned to face the fifth housing side portion 1225. Alternatively, the first housing base 1224a can be positioned at a predetermined distance from and facing the plate cover described later.

[0301] The first housing extension 1224b and the second housing extension 1224c are located at their respective ends in the second direction (Y-axis direction) on the first housing base 1224a and can be extended in the third direction (Z-axis direction).

[0302] The first housing extension 1224b and the second housing extension 1224c can contact the first housing side 1221 and the second housing side 122, respectively.

[0303] Furthermore, the fourth housing side portion 1224 may include a first projection accommodating groove G1 on its inner surface. The first projection accommodating groove G1 may include a 1-1 projection accommodating groove G1a and a 1-2 projection accommodating groove G1b.

[0304] The 1-1 projection accommodating groove G1a can be located on the surface where the first housing extension 1224b and the first housing side portion 1221 are in contact with each other. The 1-2 projection accommodating groove G1b can be located on the surface where the second housing extension 1224c and the second housing side portion 1222 are in contact with each other.

[0305] The first projection groove G1a and the first projection groove G1b can accommodate the second projection, which will be described later. The first projection groove G1a and the first projection groove G1b can be arranged side by side in the second direction (Y-axis direction). That is, the first projection groove G1a and the first projection groove G1b can overlap in the second direction (Y-axis direction). Consequently, the second projection, which is mounted in the first projection groove G1a and the first projection groove G1b, can rotate with respect to the second direction (Y-axis direction). That is, the second projection can perform a uniaxial tilt.

[0306] As described above, the 1-1 projection housing groove G1a can be positioned corresponding to the 2-1 projection housing groove G2a. And, as described above, the 1-2 projection housing groove G1b can be positioned corresponding to the 2-2 projection housing groove G2b.

[0307] The fifth housing side 1225 may be positioned opposite the fourth housing side 1224. The fifth housing side 1225 may include an opening 1225a. This allows light that has passed through or been reflected by the optical member to move through the opening 1225a.

[0308] Furthermore, the fifth housing side portion 1225 may include a housing projection 1225b. The housing projection 1225b may protrude outward. The housing 1220 can be coupled to the first camera actuator located on the outside via the housing projection 1225b. This may improve the reliability of the camera module.

[0309] Furthermore, the fifth housing side portion 1225 may include a patterned portion (not shown) having a pattern around the housing projection 1225b. The patterned portion (not shown) may be positioned with a step inside the housing projection 1225b. That is, the patterned portion (not shown) may be located inside the housing projection 1225b.

[0310] An adhesive may be applied to the patterned portion (not shown). Consequently, the contact area between the adhesive and the fifth housing side portion 1225 on the patterned portion (not shown) may increase. This may increase the coupling force between the second actuator (or housing 1220) and the first actuator.

[0311] Furthermore, the housing 1220 may include a accommodating section 1226 formed inward by the first to fifth housing sides 1221 to 1225. A mover 1230 and a rotating plate 1240 can be located in the accommodating section 1226.

[0312] Figure 17a is a perspective view of a mover according to another embodiment, Figure 17b is a perspective view of a holder according to another embodiment, Figures 17c to 17d are side views of a mover according to another embodiment, and Figure 17e is a bottom view of a mover according to another embodiment.

[0313] Referring to Figures 17a to 17e, the mover 1230 according to the embodiment may include a holder 1231 and a plate cover 1233 that covers the optical member 1232 and rotating plate 1240 mounted on the holder 1231 and connects with the holder 1231.

[0314] First, the optical element 1232 can be mounted on the holder 1231. As mentioned above, such an optical element 1232 may be a prism or a mirror, but is not limited to these.

[0315] Furthermore, the holder 1231 may include a mounting portion 1231k to which the optical member 1232 is attached. The mounting portion 1231k may be an inclined surface. Also, the holder 1231 may include a stepped portion SP at its lower part. In the holder 1231, the stepped portion SP can prevent the optical member 1232 from moving. Through this, light incident from the upper part can travel along the third direction (Z-axis direction) by passing through the optical member 1232 and the opening on the side of the fifth housing mentioned above.

[0316] Furthermore, the holder 1231 may have multiple outer surfaces. For example, the holder 1231 may have a first holder outer surface 1231S1, a second holder outer surface 1231S2, a third holder outer surface 1231S3, and a fourth holder outer surface 1231S4.

[0317] The outer surface 1231S1 of the first holder can be positioned to face the outer surface 1231S2 of the second holder. That is, the outer surface 1231S1 of the first holder can be positioned symmetrically with respect to the first direction (X-axis direction) with respect to the outer surface 1231S2 of the second holder.

[0318] The outer surface 1231S1 of the first holder can be positioned to face the side portion 1221 of the first housing. The outer surface 1231S2 of the second holder can be positioned to face the side portion 1222 of the second housing.

[0319] Furthermore, the outer surface 1231S1 of the first holder may include a first mounting groove 1231S1a. The outer surface 1231S2 of the second holder may include a second mounting groove 1231S2a. The first mounting groove 1231S1a and the second mounting groove 1231S2a may be arranged symmetrically with respect to the first direction (X-axis direction).

[0320] Furthermore, the first mounting groove 1231S1a may be used to arrange the first connecting member and the first magnet, which will be described later, and the second connecting member and the second magnet 1251b may be used to arrange the second mounting groove 1231S2a. The first magnet and the second magnet may also be arranged symmetrically with respect to the first direction (X-axis direction). In addition, the first connecting member and the second connecting member may also be arranged symmetrically with respect to the first direction (X-axis direction).

[0321] Furthermore, the first magnet and the second magnet may overlap in the second direction, and the first and second connecting members may overlap in the second direction. As mentioned above, depending on the positions of the first and second mounting grooves and the first and second magnets, the electromagnetic force induced by the magnets may be provided coaxially to the outer surface 1231S1 of the first holder and the outer surface 1231S2 of the second holder. For example, the region applied to the outer surface S1231S1 of the first holder (e.g., the part where the electromagnetic force is strongest) and the region applied to the outer surface S1231S1 of the second holder (e.g., the part where the electromagnetic force is strongest) may be located on an axis parallel to the second direction (Y-axis direction). This allows for accurate X-axis tilting.

[0322] Furthermore, the outer surfaces 1231S1 of the first holder and 1231S2 of the second holder may include additional grooves (not shown). These grooves (not shown) can reduce the weight of the holder 1231, minimizing energy consumption during uniaxial or biaxial tilt. That is, the intensity of the current applied to the first, second, and third coils can be minimized, thereby improving energy efficiency. Additionally, the aforementioned grooves (not shown) may be arranged symmetrically with respect to the first direction (X-axis direction). This prevents the center of gravity of the holder 1231 from concentrating on one side, allowing the tilt to be performed with a uniform force.

[0323] The outer surface 1231S3 of the third holder is in contact with the outer surface 1231S1 of the first holder and the outer surface 1231S2 of the second holder, and may be an outer surface that extends in the second direction (Y-axis direction) between the outer surface 1231S1 of the first holder and the outer surface 1231S2 of the second holder. As a result, the outer surface 1231S3 of the third holder can be located between the outer surface 1231S1 of the first holder and the outer surface 1231S2 of the second holder.

[0324] Furthermore, the outer surface 1231S3 of the third holder can be the bottom surface of the holder 1231. The outer surface 1231S3 of the third holder can be positioned to face the side portion 1223 of the third housing. Furthermore, the outer surface 1231S3 of the third holder can be in contact with the side portion 1223 of the third housing.

[0325] Furthermore, the outer surface 1231S3 of the third holder may include a third mounting groove 1231S3a. A third magnet 1251c may be placed in the third mounting groove 1231S3a. Also, the third housing hole 1223a may overlap with the third mounting groove 1231S3a in the first direction (X-axis direction) at least partially. Accordingly, the third magnet 1251c in the third mounting groove 1231S3a and the third coil 1252c in the third housing hole 1223a can be positioned to face each other. Then, the third magnet 1251c and the third coil 1252c generate an electromagnetic force, which allows the camera actuator to tilt along the Y axis.

[0326] Furthermore, while X-axis tilt can be achieved by multiple magnets (first and second magnets 1251a and 1251b), Y-axis tilt can be achieved solely by the third magnet 1251c.

[0327] In one example, the width of the third mounting groove 1231S3a may differ from that of the first mounting groove 1231S1a or the second mounting groove 1231S2a. For example, the width of the third mounting groove 1231S3a may be larger than that of the first mounting groove 1231S1a or the second mounting groove 1231S2a. With such a configuration, Y-axis tilt can be performed with current control similar to that of X-axis tilt.

[0328] The outer surface 1231S3 of the third holder may further include an additional groove 1231S3b. Through such grooves 1231S3b, the weight of the holder 1231 can be reduced, minimizing energy consumption during uniaxial or biaxial tilt. That is, the intensity of the current applied to the first, second, and third coils can be minimized, thereby improving energy efficiency.

[0329] Furthermore, there may be multiple grooves 1231S3b on the outer surface 1231S3 of the third holder, and if there are multiple grooves, they may be arranged symmetrically with respect to the first direction (X-axis direction).

[0330] The outer surface 1231S4 of the fourth holder is in contact with the outer surface 1231S1 of the first holder and the outer surface 1231S2 of the second holder, and may be an outer surface extending from the outer surface 1231S3 of the third holder in the first direction (X-axis direction). Furthermore, the outer surface 1231S4 of the fourth holder can be located between the outer surface 1231S1 of the first holder and the outer surface 1231S2 of the second holder.

[0331] The outer surface 1231S4 of the fourth holder can include a receiving groove PG.

[0332] A rotating plate can be fitted into the housing groove PG. In other words, the housing groove PG can accommodate a rotating plate.

[0333] In one embodiment, the accommodating groove PG may include a first accommodating groove PG1 and a second accommodating groove PG2. The first accommodating groove PG1 can accommodate the base of the rotating plate, a first base projection, and a second base projection. The second accommodating groove PG2 can accommodate the first extension projection.

[0334] The second housing groove PG2 may have a different length in the third direction from the first housing groove PG1. This allows the rotating plate in the first housing groove PG1 to be held within the mover 1230. Furthermore, the accuracy and reliability of the camera actuator according to the embodiment can all be improved.

[0335] The first storage groove PG1 may include a first storage area PG1a, a second storage area PG1b, and a third storage area PG1c, in which the base is mounted.

[0336] In one embodiment, the first storage area PG1a and the second storage area PG1b may be fitted with a first protrusion. The third storage area PG1c may be fitted with a base for a rotating plate.

[0337] The first containment area PG1a and the second containment area PG1b can be located at the top and bottom of the third containment area PG1c. Furthermore, the first containment area PG1a and the second containment area PG1b can be located on the bisector of the second direction (Y-axis direction) of the third containment area PG1c. In other words, the first containment area PG1a and the second containment area PG1b can be located in the center of the third containment area PG1c.

[0338] The second accommodating groove PG2 can be positioned adjacent to the first accommodating groove PG1, and as mentioned above, there may be multiple grooves. The second accommodating groove PG2 can be positioned above and below the first accommodating area PG1a and the second accommodating area PG1b, respectively. In one embodiment, the second accommodating groove PG2 may include the second-first accommodating groove PG2a and the second-second accommodating groove PG2b.

[0339] The second-first storage groove PG2a can be located above the first storage area PG1a. The second-second storage groove PG2b can be located below the second storage area PG1b.

[0340] The second-first housing groove PG2a and the second-second housing groove PG2b can be positioned to overlap in the first direction (X-axis direction). Alternatively, the second-first housing groove PG2a and the second-second housing groove PG2b can be positioned on the bisector of the third housing area PG1c in the second direction (Y-axis direction). Or, the second-first housing groove PG2a and the second-second housing groove PG2b can be positioned corresponding to the center of the third housing area PG1c. With such a configuration, when tilting by the first projection (e.g., biaxial tilt), the force applied between the rotating plate and the mover 1230 is not concentrated on one side. In other words, the tilt of the mover 1230 is not biased to one side, which can improve the accuracy of the tilt. Also, the force imbalance is eliminated, which can improve the reliability of the components.

[0341] Furthermore, the outer surface 1231S4 of the fourth holder may include a coupling groove 1231S4h. A coupling projection 1233p may be mounted in the coupling groove 1231S4h. This allows for coupling between the holder 1231 and the plate cover 1233. In addition, the holder 1231 and the plate cover 1233 can surround the rotating plate.

[0342] The coupling groove 1231S4h can be positioned at a distance from the receiving groove PG. Furthermore, the coupling groove 1231S4h can be located at the edge of the outer surface 1231S4 of the fourth holder. This allows the coupling force between the holder 1231 and the plate cover 1233 to be easily maintained even when a biaxial tilt is performed by the first and second protrusions located at the edge of the outer surface 1231S4 of the fourth holder.

[0343] In one embodiment, the third storage area PG1c can be located in the center of the outer surface 1231S4 of the fourth holder. The first storage area PG1a can be located above the third storage area PG1c. The second storage area PG1b can be located below the third storage area PG1c.

[0344] Furthermore, the second-first storage groove PG2a can be located above the first storage area PG1a. In other words, the first storage area PG1a can be located between the second-first storage groove PG2a and the third storage area PG1c.

[0345] Furthermore, the second-second storage groove PG2b can be located below the second storage area PG1b. In other words, the second storage area PG1b can be located between the second-second storage groove PG2b and the third storage area PG1c.

[0346] In one embodiment, the length W1 of the third accommodation area PG1c in the second direction may be greater than the lengths W2 and W3 of the first accommodation area PG1a, the second accommodation area PG1b, or the second accommodation groove PG2 in the second direction. With this configuration, when the holder 1231 and the plate cover 1233 tilt, the rotational force can be efficiently transmitted to the rotating plate through the base of the rotating plate. This can minimize resistance and improve the efficiency of the drive unit.

[0347] Furthermore, the length W2 of the first storage area PG1a or the second storage area PG1b in the second direction may be greater than the length W3 of the second storage groove PG2 in the second direction. This makes it easy to prevent the rotating plate in the storage groove PG from detaching from the holder 1231 and the plate cover 1233.

[0348] Figure 17f is a perspective view of the plate cover according to the embodiment, Figure 17g is a side view of the plate cover according to the embodiment, Figure 17h is a top view of the plate cover according to the embodiment, and Figure 17i is another side view of the plate cover according to the embodiment.

[0349] Referring to Figures 17f to 17i, the plate cover 1233 can be connected to the holder 1231 as described above.

[0350] Such a plate cover 1233 may include a plate groove 1233g, and the plate cover 1233 can surround a rotating plate through the plate groove 1233g.

[0351] In one example, the plate groove 1233g may include a first plate groove 1233g1 and a second plate groove 1233g2. The first plate groove 1233g1 can accommodate the base of the rotating plate, a first base projection, and a second base projection. The second plate groove 1233g2 can accommodate a first extension projection.

[0352] The second plate groove 1233g2 may have a different length in the third direction from the first plate groove 1233g1. This allows the rotating plate in the first plate groove 1233g1 to be held within the mover 1230. Furthermore, the accuracy and reliability of the camera actuator according to the embodiment can all be improved.

[0353] The first plate groove 1233g1 may include a first plate region 1233g1a, a second plate region 1233g1b, and a third plate region 1233g1c.

[0354] A first protrusion may be attached to the first plate region 1233g1a and the second plate region 1233g1b. A base for a rotating plate may be attached to the third plate region 1233g1c.

[0355] The first plate region 1233g1a and the second plate region 1233g1b can be located at the top and bottom of the third plate region 1233g1c. Furthermore, the first plate region 1233g1a and the second plate region 1233g1b can be located on the bisector of the third plate region 1233g1c in the second direction (Y-axis direction). In other words, the first plate region 1233g1a and the second plate region 1233g1b can be located in the center of the third plate region 1233g1c.

[0356] The second plate groove 1233g2 can be positioned adjacent to the first plate groove 1233g1, and as mentioned above, there may be multiple grooves. The second plate groove 1233g2 can be positioned above and below the first plate region 1233g1a and the second plate region 1233g1b, respectively. In an example, the second plate groove 1233g2 may include a 2-1 plate groove 1233g2a and a 2-2 plate groove 1233g2b.

[0357] The second-first plate groove 1233g2a can be located above the first plate region 1233g1a. The second-second plate groove 1233g2b can be located below the second plate region 1233g1b.

[0358] The second-first plate groove 1233g2a and the second-second plate groove 1233g2b can be positioned to overlap in the first direction (X-axis direction). Alternatively, the second-first plate groove 1233g2a and the second-second plate groove 1233g2b can be positioned on the bisector of the third plate region 1233g1c in the second direction (Y-axis direction). Or, the second-first plate groove 1233g2a and the second-second plate groove 1233g2b can be positioned corresponding to the center of the third plate region 1233g1c. With such a configuration, when tilting by the first projection (e.g., biaxial tilt), the force applied between the rotating plate and the mover 1230 is not concentrated on one side. In other words, the tilt of the mover 1230 is not biased to one side, which can improve the accuracy of the tilt. Also, the force imbalance is eliminated, which can improve the reliability of the components.

[0359] Furthermore, the plate cover 1233 may include connecting protrusions 1233p located on its inner surface. The connecting protrusions 1233p can be inserted into connecting grooves 1231S4h. This allows for connection between the holder 1231 and the plate cover 1233. In addition, the holder 1231 and the plate cover 1233 can surround a rotating plate.

[0360] The connecting projection 1233p can be positioned at a distance from the plate groove 1233g. The connecting groove 1231S4h can also be located at the edge of the plate cover 1233. This allows the bonding force between the holder 1231 and the plate cover 1233 to be easily maintained even when biaxial tilt is performed by the first and second projections located at the edge of the plate cover 1233.

[0361] In one example, the third plate region 1233g1c can be located in the center of the plate cover 1233. The first plate region 1233g1a can be located above the third plate region 1233g1c. The second plate region 1233g1b can be located below the third plate region 1233g1c.

[0362] Furthermore, the second-first plate groove 1233g2a can be located above the first plate region 1233g1a. In other words, the first plate region 1233g1a can be located between the second-first plate groove 1233g2a and the third plate region 1233g1c.

[0363] Furthermore, the second-to-second plate groove 1233g2b can be located below the second plate region 1233g1b. In other words, the second plate region 1233g1b can be located between the second-to-second plate groove 1233g2b and the third plate region 1233g1c.

[0364] The first plate groove 1233g1 can correspond to the first housing groove PG1, and the second plate groove 1233g2 can correspond to the second housing groove PG2. In this embodiment, the length of the third plate region 1233g1c in the second direction may be greater than the length of the first plate region 1233g1a, the second plate region 1233g1b, or the second plate groove 1233g2 in the second direction. With this configuration, when the holder 1231 and the plate cover 1233 tilt, the rotational force can be efficiently transmitted to the rotating plate through the base of the rotating plate. This can minimize resistance and improve the efficiency of the drive unit.

[0365] Furthermore, the length of the first plate region 1233g1a or the second plate region 1233g1b in the second direction may be greater than the length of the second plate groove 1233g2 in the second direction. This makes it easy to prevent the rotating plate in the plate groove 1233g from detaching from the holder 1231 and the plate cover 1233.

[0366] Figure 18a is a perspective view of a rotating plate according to another embodiment, Figure 18b is a perspective view of a rotating plate according to another embodiment, Figure 18c is a cross-sectional view of the rotating plate cut at AA' in Figure 18a, and Figure 18d is a top view of a rotating plate according to another embodiment.

[0367] The rotating plate 1240 according to the embodiment may include a base BS, a first projection PR1 positioned on the upper and lower surfaces of the base BS facing each other in a first direction (X-axis direction), and a second projection PR2 positioned on the sides of the base BS facing each other in a second direction (Y-axis direction). Depending on the structure, the first projection and the second projection may be formed on opposite surfaces, but this specification will describe them based on the above description.

[0368] In the embodiment, the base BS may have a rectangular shape in a plane. The length of the base BS in the second direction (Y-axis direction) may be greater than the length in the first direction (X-axis direction). However, it is not limited to this, and the base BS can consist of a variety of shapes.

[0369] As described above, the first projection PR1 can be located on the upper and lower surfaces of the base BS, respectively, which are arranged symmetrically in the first direction (X-axis direction). For example, the first projection PR1 may include the 1-1 projection on the upper surface of the base BS and the 1-2 projection on the lower surface of the base BS. However, the following description will focus on the first projection.

[0370] The first projection PR1 may include a first base projection PRB1 positioned on the base BS (upper or lower).

[0371] Furthermore, the first projection PR1 may include a first extension projection PRP1 positioned between the first base projection PRB1 and the base BS. Such a first extension projection PRP1 may be positioned on the first base projection PRb1.

[0372] The first base projection PRB1 and the first extension projection PRP1 may be circular in the plane (YZ). Accordingly, the rotating plate 1240 can easily perform tilt (second axis tilt) with respect to the first direction (X axis direction).

[0373] The first protrusion PR1 can be positioned on the bisector VL1 in the third direction (Z-axis direction) of the base BS. Furthermore, the origin (C1, C2) of the first protrusion PR1 can be positioned on the bisector VL1 in the third direction (Z-axis direction) of the base BS. Consequently, the force applied to the base BS during tilt is uniform, potentially improving the reliability of the element.

[0374] As mentioned above, the second projection PR2 can be located on two sides of the base BS that are symmetrically arranged in the second direction (Y-axis direction). For example, the second projection PR2 may include a second-first projection on one side of the base BS and a second-second projection on the other side of the base BS. However, the following description will focus on the second projection.

[0375] The second projection PR2 may include a second base projection PRB2 positioned on the base BS (on the side).

[0376] Furthermore, the second projection PR2 may include a second extension projection PRP2 positioned between the second base projection PRB2 and the base BS. Such a second extension projection PRP2 may be positioned on the second base projection PRb2.

[0377] The second base projection PRB2 and the second extension projection PRP2 may be circular in the plane (XZ). Accordingly, the rotating plate 1240 can easily perform tilt (first axis tilt) with respect to the second direction (Y axis direction).

[0378] The second projection PR2 can be positioned on the bisector of the base BS in the first direction (X-axis direction). Furthermore, the origin of the second projection PR2 can be positioned on the bisector of the base BS in the third direction (Z-axis direction). Consequently, the force applied to the base BS during tilt is uniform, potentially improving the reliability of the element.

[0379] Furthermore, as mentioned above, the first protrusion PR1 can be multiple and may overlap in the first direction (X-axis direction). Similarly, as mentioned above, the second protrusion PR2 can be multiple and may overlap in the second direction (Y-axis direction). Consequently, the camera actuator according to the embodiment can perform precise tilting.

[0380] Furthermore, the length W4 of the base BS in the second direction (Y-axis direction) may be greater than the lengths r1 and r2 of the first base projection PRB1 and the first extension projection PRP1 in the second direction (Y-axis direction). As mentioned above, since the first base projection PRB1 and the first extension projection PRP1 are circular in a plane, the lengths r1 and r2 in the second direction (Y-axis direction) can be their diameters, and this will be used as the basis for the explanation. With this configuration, rotational force can be efficiently transmitted to the rotating plate through the base of the rotating plate. This minimizes resistance and improves the efficiency of the drive unit.

[0381] Furthermore, the first protrusion PR1 can come into contact with the lubricant applied in the second housing groove PG2 and the second plate groove 1223g2. The second protrusion PR2 can come into contact with the lubricant applied in the first projection housing groove G1 and the second projection housing groove G2.

[0382] Furthermore, the diameter r1 of the first base projection PRB1 in the embodiment may be larger than the diameter r2 of the first extension projection PRP1. Accordingly, the first base projection PRB1 prevents the rotating plate 1240 from separating between the holder and the plate cover in the first direction (X-axis direction).

[0383] Furthermore, the length h1 of the base BS in the first direction (X-axis direction) may be greater than the lengths h2 and h3 of the second base projection PRB2 and the second extension projection PRP2 in the first direction (X-axis direction). As mentioned above, since the second base projection PRB2 and the second extension projection PRP2 are circular in a plane, the lengths h2 and h3 in the first direction (X-axis direction) can be their diameters, and this will be used as the basis for explanation. With the above configuration, rotational force can be efficiently transmitted to the rotating plate through the base of the rotating plate. This minimizes resistance and improves the efficiency of the drive unit.

[0384] Furthermore, the diameter h2 of the second base projection PRB2 in the embodiment may be larger than the diameter h3 of the second extension projection PRP2. Accordingly, the second base projection PRB2 prevents the rotating plate 1240 from separating between the holder and the plate cover in the second direction (Y-axis direction).

[0385] Figure 19 is a diagram illustrating a drive unit according to another embodiment.

[0386] Referring to Figure 19, as mentioned above, the drive unit 1250 includes a drive magnet 1251, a drive coil 1252, a Hall sensor unit 1253, a coupling unit 1254, and a substrate unit 1255.

[0387] Furthermore, as mentioned above, the drive magnet 1251 may include a first magnet 1251a, a second magnet 1251b, and a third magnet 1251c that provide driving force by electromagnetic force. The first magnet 1251a, the second magnet 1251b, and the third magnet 1251c can each be located on the outer surface of the holder 1231.

[0388] Furthermore, the drive coil 1252 may include multiple coils. For example, the drive coil 1252 may include a first coil 1252a, a second coil 1252b, and a third coil 1252c.

[0389] The first coil 1252a can be positioned opposite the first magnet 1251a. This allows the first coil 1252a to be located in the first housing hole 1221a of the first housing side 1221, as described above. The second coil 1252b can be positioned opposite the second magnet 1251b. This allows the second coil 1252b to be located in the second housing hole 1222a of the second housing side 1222, as described above.

[0390] The second camera actuator according to this embodiment controls the rotation of the mover 1230 in a first direction (X-axis direction) or a second direction (Y-axis direction) by the electromagnetic force between the drive magnet 1251 and the drive coil 1252, thereby minimizing the occurrence of descent and tilt phenomena when OIS is implemented and providing the best possible optical characteristics.

[0391] Furthermore, according to the embodiment, by realizing OIS through the rotating plate 1240 of the rotating plate positioned between the housing 1220 and the mover 1230, the size limitations of the actuator can be overcome, and an ultra-slim, ultra-compact camera actuator and a camera module including the same can be provided.

[0392] The connecting portion 1254 may include a first connecting member 1254a, a second connecting member 1254b, and a third connecting member 1254c.

[0393] Furthermore, the first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c can each be positioned between the first magnet 1251a to the third magnet 1251c and the holder 1231.

[0394] The first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c can be yokes. Accordingly, the first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c can each be connected to the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c, respectively.

[0395] Furthermore, the first connecting member 1254a, the second connecting member 1254b, and the third connecting member 1254c are each positioned within the first mounting groove, the second mounting groove, and the third mounting groove, and can be easily bonded to the first mounting groove, the second mounting groove, and the third mounting groove through adhesive members injected through grooves formed in the first mounting groove, the second mounting groove, and the third mounting groove.

[0396] The substrate portion 1255 may include a first substrate side portion 1255a, a second substrate side portion 1255b, and a third substrate side portion 1255c.

[0397] The first substrate side portion 1255a and the second substrate side portion 1255b may be arranged to face each other. The third substrate side portion 1255c may be located between the first substrate side portion 1255a and the second substrate side portion 1255b.

[0398] Furthermore, the first substrate side portion 1255a can be located between the first housing side portion and the shield can, and the second substrate side portion 1255b can be located between the second housing side portion and the shield can. Also, the third substrate side portion 1255c can be located between the third housing side portion and the shield can, and may be the bottom surface of the substrate portion 1255.

[0399] The first substrate side portion 1255a can be coupled to the first coil 1252a and electrically connected. Furthermore, the first substrate side portion 1255a can be coupled to the first Hall sensor 1253a and electrically connected.

[0400] The second substrate side portion 1255b may be electrically connected by coupling with the second coil 1252b. It should also be understood that the second substrate side portion 1255b may be electrically connected by coupling with the second Hall sensor 1253b.

[0401] Furthermore, the first substrate side portion 1255a and the second substrate side portion 1255b may be extended in a third direction (Z-axis direction). In contrast, the first substrate side portion 1255a and the second substrate side portion 1255b may have regions that extend from the fifth housing side portion in a third direction (Z-axis direction).

[0402] Furthermore, the third substrate side portion 1255c can be electrically connected by coupling with the third coil 1252c. Also, the third substrate side portion 1255c can be electrically connected by coupling with the third Hall sensor 1253c.

[0403] Figure 20 is a perspective view of the second camera actuator in an embodiment in which the shield can and substrate have been removed, Figure 21a is a cross-sectional view taken at BB' in Figure 20, Figure 21b is a cross-sectional view taken at CC' in Figure 20, and Figure 21c is a cross-sectional view taken at DD' in Figure 20.

[0404] Referring to Figures 20 and 21a to 21c, the first coil 1252a can be located on the first housing side portion 1221, and the first magnet 1251a and the first coupling member 1254a can be located on the first holder outer surface 1231S1 of the holder 1231.

[0405] Furthermore, the first coil 1252a and the first magnet 1251a can be positioned facing each other. The first magnet 1251a can overlap the first coil 1252a in the second direction (Y-axis direction) at least partially. Also, the first connecting member 1254a can overlap the first coil 1252a in the second direction (Y-axis direction) at least partially.

[0406] Furthermore, the second coil 1252b can be located on the side portion 1222 of the second housing, and the second magnet 1251b and the second coupling member 1254b can be located on the outer surface 1231S2 of the second holder 1231. This allows the second coil 1252b and the second magnet 1251b to be positioned opposite each other. The second magnet 1251b can overlap the second coil 1252b in the second direction (Y-axis direction) at least partially. Also, the second coupling member 1254b can overlap the second coil 1252b in the second direction (Y-axis direction) at least partially.

[0407] Furthermore, the first coil 1252a and the second coil 1252b may overlap in the second direction (Y-axis direction), and the first magnet 1251a and the second magnet 1251b may overlap in the second direction (Y-axis direction). With this configuration, the electromagnetic force applied to the outer surfaces of the holder (outer surface of the first holder and outer surface of the second holder) is located on an axis parallel to the second direction (Y-axis direction), allowing for accurate and precise X-axis tilt.

[0408] Furthermore, as described above, the first Hall sensor 1253a and the second Hall sensor 1253b can be located on the outside for electrical connection and coupling with the substrate portion 1255. However, they are not limited to this position.

[0409] Furthermore, the third coil 1252c can be located on the side portion 1223 of the third housing, and the third magnet 1251c can be located on the outer surface 1231S3 of the holder 1231. The third coil 1252c and the third magnet 1251c can overlap at least partially in the first direction (X-axis direction). Accordingly, the strength of the electromagnetic force between the third coil 1252c and the third magnet 1251c can be easily controlled.

[0410] As described above, the rotating plate 1240 can be positioned between the fourth holder outer surface 1231S4 of the holder 1231 and the plate cover 1233 (or the fourth housing side portion 1224).

[0411] On the outer surface 1231S4 of the fourth holder, a first housing groove PG1 located in the center in the second direction (Y-axis direction) and a second housing groove PG2 located above and below the first housing groove PG1 may be arranged. In other words, a rotating plate 1240 may be mounted in the housing groove PG of the outer surface 1231S4 of the fourth holder. That is, the rotating plate 1240 can be located in the first housing groove PG1 and the second housing groove PG2.

[0412] Furthermore, the rotating plate 1240 can be located in the first plate groove 1233g1 and the second plate groove 1233g2. However, a portion of the second projection PR2 can be located in the aforementioned first projection accommodating groove and second projection accommodating groove.

[0413] Furthermore, the base BS can be located in the third containment area PG1c and the third plate area 1233g1c. The first base projection PRB1 of the first protrusion PR1 can be located in the first containment area PG1a and the first plate area 1233g1a. The first base projection PRB1 of the first protrusion PR1 can also be located in the second containment area PRG1b and the second plate area 1233g1b.

[0414] As an example, the bottom surface LS of the first housing groove PG1 may be spaced apart from the base BS, the first base projection PRB1, and the second base projection PRB2 in a third direction (Z-axis direction). Also, the bottom surface of the first plate groove 1233g1 may be spaced apart from the base BS, the first base projection PRB1, and the second base projection PRB2 in a third direction (Z-axis direction). With this configuration, space is secured between the holder 1231 and the plate cover 1233 for the rotating plate 1240 to perform biaxial tilt, so that biaxial tilt can be performed accurately.

[0415] As an example, the side surface SS of the first housing groove PG1 may overlap at least partially with the base BS, the first base projection PRB1, and the second base projection PRB2 in the first direction (X-axis direction). Similarly, the side surface SS of the first plate groove 1233g1 may overlap at least partially with the base BS, the first base projection PRB1, and the second base projection PRB2 in the first direction (X-axis direction). With this configuration, the rotating plate 1240 can be prevented from separating between the holder 1231 and the plate cover 1233 in the first direction (X-axis direction) or the second direction (Y-axis direction).

[0416] Furthermore, the second housing groove PG2 may overlap with the first base projection PRB1 and base BS in the third direction (Z-axis direction). Also, the second plate groove 1233g2 may overlap with the first base projection PRB1 and base BS in the third direction (Z-axis direction).

[0417] Furthermore, the shape of the second accommodating groove PG2 can correspond to that of the first extension projection PRP1. As a result, the second accommodating groove PG2 can be circular in planar shape, just like the first extension projection PRP1.

[0418] Furthermore, the shapes of the first projection housing groove G1 and the second projection housing groove G2 can correspond to those of the second extension projection PRP2. As a result, the first projection housing groove G1 and the second projection housing groove G2 can be circular in planar shape, just like the second extension projection PRP2.

[0419] The length of the second accommodating groove PG2 in the third direction (Z-axis direction) may be smaller than the length of the first accommodating groove PG1 in the third direction (Z-axis direction).

[0420] Furthermore, the second housing groove PG2 can be separated from the first extension projection PRP1 by a predetermined distance, at least in part. This ensures that there is space for the holder 1231 and the plate cover 1233 to tilt (first axis tilt) with respect to the second direction (Y axis direction).

[0421] Furthermore, the first projection housing groove G1 and the second projection housing groove G2 can be spaced a predetermined distance apart from the second extension projection PRP2. This ensures that there is space for the holder 1231 and the plate cover 1233 to tilt (second axis tilt) with respect to the first direction (X-axis direction).

[0422] In other words, there can be separation spaces gg1, gg2, gg3, and gg4 between the base BS and the holder 1231 or between the base BS and the plate cover 1233. This allows the base BS of the rotating plate 1240 to not come into contact with the holder 1231 or the plate cover 1233 during two-axis tilting, thus facilitating two-axis tilting.

[0423] Figure 22 is an illustrative diagram of the movement of the second camera actuator shown in Figure 21a, and Figure 23 is an illustrative diagram of the movement of the second camera actuator shown in Figure 21c.

[0424] Referring to Figure 22, Y-axis tilt can be performed. That is, OIS can be realized by rotating in the first direction (X-axis direction).

[0425] In one embodiment, a third magnet 1251c positioned at the bottom of the holder 1231 forms an electromagnetic force with the third coil 1252c, causing the mover 1230 to tilt or rotate in a first direction (X-axis direction). That is, the aforementioned electromagnetic force allows the holder 1231 and the plate cover 1233 coupled to the holder 1231 to move in a first direction (X-axis direction).

[0426] The rotating plate 1240 can rotate or tilt with respect to the second projection PR2 (e.g., the second extension projection) extending in the second direction as the reference axis (or axis of rotation). That is, the rotating plate 1240 can perform Y-axis tilt (or first-axis tilt) with respect to the second projection PR2 as the reference axis.

[0427] For example, OIS implementation can be achieved by first electromagnetic forces F1A and F1B between the third magnet 1251c positioned in the third mounting groove and the third coil 1252c positioned on the side of the third substrate, causing the mover 1230 to rotate in the X-axis direction by a first angle θ1 (X1->X1a or X1->X1b). The first angle θ1 may be ±1° to ±3°, but is not limited to this.

[0428] Referring to Figure 23, an X-axis tilt can be performed. That is, rotation in the second direction (Y-axis direction) can be used to realize OIS.

[0429] OIS implementation can be achieved while the mover 1230 tilts or rotates in the Y-axis direction (or tilts along the X-axis).

[0430] In one embodiment, the first magnet 1251a and the second magnet 1251b, positioned on the holder 1231, each form an electromagnetic force with the first coil 1252a and the second coil 1252b, respectively, causing the rotating plate 1240 and the mover 1230 to tilt or rotate in the second direction (Y-axis direction). That is, the aforementioned electromagnetic force allows the holder 1231 and the plate cover 1233 coupled to the holder 1231 to rotate or move in the second direction (Y-axis direction).

[0431] The rotating plate 1240 can rotate or tilt (X-axis tilt) in a second direction with the first projection PR1 (e.g., the first extension projection) as the reference axis (or rotation axis).

[0432] For example, OIS (Optical Inertial Stabilization) can be achieved by the second electromagnetic forces F2A and F2B between the first and second magnets 1251a and 1251b positioned in the first mounting groove and the first and second coil sections 1252a and 1252b positioned on the sides of the first and second substrates, causing the mover 1230 to rotate by a second angle θ2 in the Y-axis direction (Y1->Y1a or Y1->Y1b). The second angle θ2 may be ±1° to ±3°, but is not limited to this.

[0433] Thus, the second camera actuator according to this embodiment controls the rotation of the rotating plate 1240 and the mover 1230 in a first direction (X-axis direction) or a second direction (Y-axis direction) by the electromagnetic force between the drive magnet in the holder and the drive coil arranged in the housing, thereby minimizing the occurrence of descent and tilt phenomena when OIS is implemented and providing the best optical characteristics. Furthermore, as mentioned above, "Y-axis tilt" corresponds to rotation or tilt in the first direction (X-axis direction), and "X-axis tilt" corresponds to rotation or tilt in the second direction (Y-axis direction).

[0435] Figure 24 is a perspective view of an AF or Zoom actuator according to another embodiment of the present invention, Figure 25 is a perspective view of the actuator according to the embodiment shown in Figure 24 with some components omitted, and Figure 26 is an exploded perspective view of the actuator according to the embodiment shown in Figure 24 with some components omitted.

[0436] Referring to Figure 24, the actuator 2100 according to this embodiment may include a base 2020, a circuit board 2040 and drive unit 2142 and a third lens assembly 2130 located outside the base 2020.

[0437] Figure 25 is a perspective view of Figure 24 in which the base 2020 and circuit board 2040 are omitted. Referring to Figure 25, the actuator 2100 according to the embodiment may include a first guide section 2210, a second guide section 2220, a first lens assembly 2110, a second lens assembly 2120, a drive unit 2141, and a drive unit 2142.

[0438] The drive units 2141 and 2142 may include coils or magnets.

[0439] For example, if the drive unit 2141 and the drive unit 2142 include coils, the drive unit 2141 may include a first coil section 2141b and a first yoke 2141a, and the drive unit 2142 may include a second coil section 2142b and a second yoke 2142a.

[0440] Alternatively, the drive unit 2141 and drive unit 2142 may include magnets.

[0441] Referring to Figure 26, the actuator 2100 according to the embodiment may include a base 2020, a first guide portion 2210, a second guide portion 2220, a first lens assembly 2110, a second lens assembly 2120, and a third lens assembly 2130.

[0442] For example, the actuator 2100 according to the embodiment may include a base 2020, a first guide portion 2210 disposed on one side of the base 2020, a second guide portion 2220 disposed on the other side of the base 2020, a first lens assembly 2110 corresponding to the first guide portion 2210, a second lens assembly 2120 corresponding to the second guide portion 2220, a first ball 2117 (see Figure 27a) disposed between the first guide portion 2210 and the first lens assembly 2110, and a second ball (not shown) disposed between the second guide portion 2220 and the second lens assembly 2120.

[0443] Furthermore, the embodiment may include a third lens assembly 2130 positioned in front of the first lens assembly 2110 in the optical axis direction.

[0444] Referring to Figures 25 and 26, the embodiment may include a first guide portion 2210 positioned adjacent to the first side wall of the base 2020 and a second guide portion 2220 positioned adjacent to the second side wall of the base 2020.

[0445] The first guide section 2210 may be positioned between the first lens assembly 2110 and the first side wall of the base 2020.

[0446] The second guide section 2220 may be positioned between the second lens assembly 2120 and the second side wall of the base 2020. The first and second side walls of the base 2020 may be positioned facing each other.

[0447] According to the embodiment, by driving the lens assembly with the precisely numerically controlled first guide section 2210 and second guide section 2220 coupled within the base 2020, friction torque is reduced and frictional resistance is lowered, resulting in technical effects such as improved driving force, reduced power consumption, and improved control characteristics during zooming.

[0448] Accordingly, according to the embodiment, during zooming, friction torque is minimized while preventing phenomena such as lens descent, lens tilt, and misalignment of the lens group and the central axis of the image sensor, thereby significantly improving image quality and resolution.

[0449] In particular, according to this embodiment, by not placing guide rails on the base itself, and instead employing a first guide section 2210 and a second guide section 2220 that are formed and assembled separately from the base 2020, there is a special technical effect that prevents the occurrence of a gradient depending on the injection direction.

[0450] In this embodiment, the first guide section 2210 and the second guide section 2220 are injected along the X-axis, and the length injected may be shorter than the base 2020. In this case, when rails are placed on the first guide section 2210 and the second guide section 2220, the generation of a gradient during injection can be minimized, resulting in a technical effect where the straightness of the rail is less likely to be distorted.

[0451] More specifically, Figure 27a is a perspective view of the first lens assembly 2110 of the actuator according to the embodiment shown in Figure 26, and Figure 27b is a perspective view of the first lens assembly 2110 shown in Figure 27a with some components removed.

[0452] Referring to Figure 26, the embodiment may include a first lens assembly 2110 that moves along a first guide portion 2210 and a second lens assembly 2120 that moves along a second guide portion 2220.

[0453] Referring again to Figure 27a, the first lens assembly 2110 may include a first lens barrel 2112a on which the first lens 2113 is located and a first drive unit housing 2112b on which the drive unit 2116 is located. The first lens barrel 2112a and the first drive unit housing 2112b may be a first housing, and the first housing may be in the shape of a barrel or lens barrel. The drive unit 2116 may be, but is not limited to, a drive magnet, and may optionally be a coil.

[0454] The second lens assembly 2120 may also include a second lens barrel (not shown) on which a second lens (not shown) is arranged, and a second drive unit housing (not shown) on which a drive unit (not shown) is arranged. The second lens barrel (not shown) and the second drive unit housing (not shown) may be a second housing, and the second housing may be in the shape of a barrel or lens barrel. The drive unit may be, but is not limited to, a drive magnet, and may optionally be a coil.

[0455] The drive unit 2116 can correspond to two first rails 2212.

[0456] The embodiment can be driven using one or more balls. For example, the embodiment may include a first ball 2117 positioned between a first guide portion 2210 and a first lens assembly 2110, and a second ball (not shown) positioned between a second guide portion 2220 and a second lens assembly 2120.

[0457] For example, in this embodiment, the first ball 2117 may include one or more first-first balls 2117a positioned on the upper side of the first drive housing 2112b and one or more first-second balls 2117b positioned on the lower side of the first drive housing 2112b.

[0458] In this embodiment, the 1-1 ball 2117a of the first ball 2117 can move along the 1-1 rail 2212a, which is one of the first rails 2212, and the 1-2 ball 2117b of the first ball 2117 can move along the other 1-2 rail 2212b of the first rails 2212.

[0459] According to the embodiment, by having the first guide section comprise a 1-1 rail and a 1-2 rail, the 1-1 rail and the 1-2 rail guide the first lens assembly 2110, thereby providing a technical effect that can improve the accuracy of optical axis alignment with the second lens assembly 2110 when the first lens assembly 2110 moves.

[0460] Referring to Figure 27b, in this embodiment, the first lens assembly 2110 may include a first assembly groove 2112b1 in which the first ball 2117 is positioned. The second lens assembly 2120 may include a second assembly groove (not shown) in which the second ball is positioned.

[0461] The first lens assembly 2110 may have multiple first assembly grooves 2112b1. In this case, with respect to the optical axis direction, the distance between two of the multiple first assembly grooves 2112b1 may be longer than the thickness of the first lens barrel 2112a.

[0462] In the embodiment, the first assembly groove 2112b1 of the first lens assembly 2110 may be V-shaped. Also, the second assembly groove (not shown) of the second lens assembly 2120 may be V-shaped. In addition to being V-shaped, the first assembly groove 2112b1 of the first lens assembly 2110 may be U-shaped or have a shape that contacts the first ball 2117 at two or three points. In addition to being V-shaped, the second assembly groove (not shown) of the second lens assembly 2120 may be U-shaped or have a shape that contacts the second ball at two or three points.

[0463] Referring to Figures 26 and 27a, in the embodiment, the first guide portion 2210, the first ball 2117, and the first assembly groove 2112b1 may be positioned on a virtual straight line from the first side wall to the second side wall. The first guide portion 2210, the first ball 2117, and the first assembly groove 2112b1 may be positioned at the first side wall between the second side walls.

[0464] Next, Figure 28 is a perspective view of the third lens assembly 2130 of the actuator according to the embodiment shown in Figure 26.

[0465] Referring to Figure 28, in this embodiment, the third lens assembly 2130 includes a third housing 2021, a third barrel, and a third lens 2133.

[0466] In this embodiment, the third lens assembly 2130 is provided with a barrel recess 2021r at the upper end of the third barrel, which allows the thickness of the third barrel of the third lens assembly 2130 to be kept constant, resulting in a combination of technical effects that can reduce the amount of injection material and improve the accuracy of numerical control.

[0467] Furthermore, according to the embodiment, the third lens assembly 2130 may be provided with a housing rib 2021a and a housing recess 2021b in the third housing 2021.

[0468] In this embodiment, the third lens assembly 2130 has a combined technical effect: by providing a housing recess 2021b in the third housing 2021, the amount of injection material is reduced and the accuracy of numerical control is improved; and by providing a housing rib 2021a in the third housing 2021, strength is ensured.

[0469] Figure 29 is a perspective view of a mobile terminal to which the camera module according to the embodiment is applied.

[0470] As shown in Figure 29, the mobile terminal 1500 of the embodiment may include a camera module 1000, a flash module 1530, and an autofocus device 1510 provided on the rear.

[0471] The camera module 1000 may include an image capture function and an autofocus function. For example, the camera module 1000 may include an autofocus function that utilizes the image.

[0472] The camera module 1000 processes still images or video frames obtained by the image sensor in shooting mode or video call mode.

[0473] The processed image frame can be displayed on a designated display unit and stored in memory. A camera (not shown) may also be located on the front of the mobile terminal body.

[0474] For example, camera module 1000 may include a first camera module 1000 and a second camera module 1000, and the first camera module 1000A may enable OIS implementation along with AF or zoom functionality.

[0475] The flash module 1530 may include a light-emitting element that emits light internally. The flash module 1530 can be activated by the camera operation of the mobile terminal or by user control.

[0476] The autofocus device 1510 may include one of the packages of surface light emission laser elements as the light-emitting unit.

[0477] The autofocus device 1510 may include a laser-based autofocus function. The autofocus device 1510 may be primarily used in conditions where the autofocus function using the image from the camera module 1000 is impaired, such as close-range shots of 10m or less or in dark environments.

[0478] The autofocus device 1510 may include a light-emitting section containing a vertical cavity surface-emitting laser (VCSEL) semiconductor element and a light-receiving section such as a photodiode that converts light energy into electrical energy.

[0479] Figure 30 is a perspective view of a vehicle to which the camera module according to the embodiment is applied.

[0480] For example, Figure 30 is an external view of a vehicle equipped with a vehicle driving assistance device to which the camera module 1000 according to the embodiment is applied.

[0481] Referring to Figure 30, the vehicle 700 of the embodiment may be equipped with wheels 13FL, 13FR that rotate by a power source, and a predetermined sensor. The sensor may be, but is not limited to, a camera sensor 2000.

[0482] The camera 2000 may be a camera sensor to which the camera module 1000 according to the embodiment is applied. The vehicle 700 of the embodiment can acquire video information through the camera sensor 2000 which captures forward or surrounding video, and can use the video information to determine the lane unidentified situation and generate a virtual lane when it is unidentified.

[0483] For example, the camera sensor 2000 captures images of the area in front of the vehicle 700 to obtain forward-facing video footage, and a processor (not shown) can analyze objects contained in this forward-facing video footage to obtain video information.

[0484] For example, if the video captured by the camera sensor 2000 includes objects such as lanes, adjacent vehicles, obstacles to driving, and indirect road markings such as median strips, curbs, and street trees, the processor can detect these objects and include them in the video information. At this time, the processor can acquire distance information to the objects detected through the camera sensor 2000 and further supplement the video information.

[0485] The video information may be information about objects captured in the video. Such a camera sensor 2000 may include an image sensor and a video processing module.

[0486] The camera sensor 2000 can process still images or videos obtained by an image sensor (e.g., CMOS or CCD).

[0487] The image processing module can process still images or videos acquired through the image sensor, extract necessary information, and transmit the extracted information to the processor.

[0488] At this time, the camera sensor 2000 may include, but is not limited to, a stereo camera to improve the accuracy of object measurement and to secure further information such as the distance between the vehicle 700 and the object.
