Description

Technical Field

[0001] The present invention relates to camera actuators and camera devices including the camera actuators. Background Technology

[0002] A camera is a device that captures images of a subject or moving images and is mounted in portable devices, drones, vehicles, etc. To improve image quality, camera devices may have image stabilization functions that correct or prevent image shake caused by user movement, autofocus (AF) functions that automatically adjust the distance between the image sensor and the lens to adjust the focal length of the lens arrangement, and zooming functions that use zoom lenses to increase or decrease the magnification of the subject to capture images of distant subjects.

[0003] Meanwhile, as the number of pixels in an image sensor increases, the resolution increases, and the pixel size decreases. With the smaller size, the amount of light received by a pixel in the same amount of time decreases. Therefore, as the number of pixels in a camera increases, image shake caused by camera shakiness due to slower shutter speeds in dark environments may become more severe. Optical image stabilization (OIS), which corrects motion by altering the optical path, is a typical image stabilization technique.

[0004] According to conventional OIS technology, camera motion can be detected using a gyroscope or similar device, and then the lens or camera module, including the lens and image sensor, can be tilted or moved based on the detected motion. When tilting or moving the lens or camera module, including the lens and image sensor, additional space needs to be ensured around the lens or camera module for tilting or movement.

[0005] Meanwhile, the actuator for OIS can be positioned around the lens. In this case, the actuator for OIS may include an actuator responsible for tilting relative to two axes perpendicular to the optical axis.

[0006] However, due to the recent demand for ultra-thin and ultra-compact camera devices, there are already many space constraints on the arrangement of actuators for OIS, etc., and it may be difficult to ensure sufficient space for lenses or camera modules including lenses and image sensors for OIS tilting or movement. Furthermore, as the number of camera pixels increases, it is preferable to increase the size of the lenses to increase the amount of light received, but there may be limitations on increasing the size of the lenses due to the space occupied by the actuators used for OIS.

[0007] Furthermore, when the camera module has all the functions of zoom, AF, and OIS, there is a problem that the magnets used for OIS and the magnets used for AF or zoom are arranged closely together, which can cause magnetic field interference. Summary of the Invention

[0112] Because this invention allows for various variations and has many embodiments, specific embodiments will be illustrated and described in the accompanying drawings. However, this is not intended to limit the invention to the specific embodiments, and it is to be understood that all variations, equivalents, and alternatives falling within the spirit and scope of this invention are covered herein.

[0113] Although the terms “second,” “first,” etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, a second element may be referred to as a first element, and a first element may be similarly referred to as a second element without departing from the scope of the invention. The term “and / or” includes any one or any combination of the plurality of associated listed items.

[0114] When a component is described as being “connected” or “coupled” to another component, it is understood that the component can be directly connected to or coupled to another component, or that other components may exist in between. Conversely, when a component is described as being “directly connected” or “directly coupled” to another component, it is understood that no intervening component exists.

[0115] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms are intended to include the plural forms unless the context clearly indicates otherwise. It should be further understood in this specification that the terms “comprising,” “including,” “including,” and / or “comprising” as used herein specify the presence of stated features, numbers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, numbers, steps, operations, elements, components, and groups thereof.

[0116] Unless otherwise defined, all terms used herein, including technical and scientific terms, shall have the same meaning as commonly understood by one of skill in the art. Terms, such as those defined in common dictionaries, shall be interpreted as having the meaning consistent with their meaning in the context of the relevant art, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0117] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Components that are the same or corresponding to each other will be indicated by the same or corresponding reference numerals, regardless of the symbols in the drawings, and redundant descriptions will be omitted.

[0118] Figure 1 This is a perspective view of a camera module according to an embodiment. Figure 2a The diagram shows the shield can coming from... Figure 1 The perspective view of the removed state in the camera module shown in the diagram, and Figure 2b The diagram is in Figure 2a The diagram shows a plan view of the camera module.

[0119] refer 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 protective cover 1210.

[0120] refer to Figure 1 , 2a As with all of 2b, the first camera module 1000A may include a single actuator or multiple actuators. For example, the first camera module 1000A may include a first camera actuator 1100 and a second camera actuator 1200.

[0121] The first camera actuator 1100 can be electrically connected to the first set of circuit boards 1410, the second camera actuator 1200 can be electrically connected to the second set of circuit boards 1420, and, although not shown in the figures, the second set of circuit boards 1420 can also be electrically connected to the first set of circuit boards 1410. The second camera module 1000B can be electrically connected to the third set of circuit boards 1430.

[0122] The first camera actuator 1100 may be a zoom actuator or an autofocus (AF) actuator. For example, the first camera actuator 1100 may support a single lens or multiple lenses and perform AF or zoom functions by moving the lenses according to control signals from a predetermined control unit.

[0123] The second camera actuator 1200 can be an optical image stabilization (OIS) actuator.

[0124] The second camera module 1000B may include a lens disposed in a predetermined lens barrel (not shown). The lens may include a fixed focal length lens. A fixed focal length lens may be referred to as a "single focal length lens" or "single lens".

[0125] The second camera module 1000B can be housed in a predetermined housing (not shown) and may include an actuator (not shown) for driving the lens section. The actuator may be a voice coil motor, a micro actuator, a silicone actuator, etc., and can be applied in various ways such as electrostatic, thermal, bimorph, and electrostatic force methods, but the present invention is not limited thereto.

[0126] Next, Figure 3a It is a diagram. Figure 2a The diagram shows a perspective view of the first camera module, and... Figure 3b The diagram is in Figure 3a The figure shows a side cross-sectional view of the first camera module.

[0127] refer to Figure 3a The first camera module 1000A may include a first camera actuator 1100 that performs zoom and AF functions, and a second camera actuator 1200 disposed on one side of the first camera actuator 1100 and performing OIS functions.

[0128] refer to Figure 3b The first camera actuator 1100 may include an optical system and a lens drive unit. For example, at least one of the first lens assembly 1110, the second lens assembly 1120, the third lens assembly 1130, and the guide pin 50 may be disposed in the first actuator 1100.

[0129] In addition, the first camera actuator 1100 may include a drive coil 1140 and a drive magnet 1160 to perform high magnification scaling.

[0130] For example, the first lens assembly 1110 and the second lens assembly 1120 can be movable lenses moved by the drive coil 1140, the drive magnet 1160, and the guide pin 50, and the third lens assembly 1130 can be a fixed lens, but the invention is not limited thereto. For example, the third lens assembly 1130 can function as a focuser, collecting light to form an image at a specific location, and the first lens assembly 1110 can function as a variator, re-forming an image at another location through the third lens assembly 1130. Simultaneously, the first lens assembly 1110 can be in a state of large magnification variation because the distance to the subject or the image distance is greatly changed, and the first lens assembly 1110, as a variator, can play an important role in changing the focal length or magnification of the optical system. Furthermore, the image points formed by the first lens assembly 1110 as a variator can vary slightly depending on the position. Therefore, the second lens assembly 1120 can perform a position compensation function on the image formed by the variator. For example, the second lens assembly 1120 can perform the function of a compensator, which is used to accurately form an image formed by the first lens assembly 1110 as a changer at the actual location of the image sensor 1190.

[0131] For example, the first lens assembly 1110 and the second lens assembly 1120 can be driven by electromagnetic force generated by the interaction between the drive coil 1140 and the drive magnet 1160.

[0132] Furthermore, the predetermined image sensor 1190 can be configured to be perpendicular to the optical axis of the collimated light.

[0133] Next, details of the second camera actuator 1200 will be referenced. Figure 4 describe.

[0134] Furthermore, the camera module according to the embodiment can use a camera actuator to control the optical path to implement OIS, and accordingly, it can minimize the occurrence of downsloping or tilting phenomena and achieve optimal optical properties.

[0135] because Figures 1 to 3a and Figure 3b The description is intended to illustrate the overall structure and operating principle of the camera module according to embodiments of the present invention, and the embodiments of the present invention are not limited to those described herein. Figures 1 to 3a and Figure 3b The detailed configuration is shown in the diagram.

[0136] Furthermore, when the OIS actuator and the AF or zoom actuator are configured according to an embodiment of the present invention, magnetic field interference with the AF or zoom magnet can be prevented when OIS is executed. Because the drive magnet of the second camera actuator 1200 is separately configured from the first camera actuator 1100, magnetic field interference between the first camera actuator 1100 and the second camera actuator 1200 can be prevented. In this specification, OIS can be used interchangeably with terms such as hand-shake correction, optical image stabilization, optical image correction, and shake correction.

[0137] The control method and detailed structure of the second actuator according to an embodiment of the present invention will be described in more detail below.

[0138] Figure 4 This is a perspective view illustrating a second camera actuator according to an embodiment, and Figure 5 This is an exploded perspective view illustrating a second camera actuator according to an embodiment.

[0139] refer to Figure 4 and Figure 5 The second camera actuator 1200 according to an embodiment includes a protective cover 1210, a housing 1220, a mover 1230, a guide 1240, and a drive 1250. Furthermore, it should be understood that the components are not assembled along the lines illustrated in the exploded perspective view (e.g., double-dotted lines).

[0140] First, the mover 1230 includes a retainer 1231 and an optical component 1232 disposed on the retainer 1231. The guide portion 1240 includes a support portion 1241, a first elastic portion 1242 connecting the support portion 1241 to the housing 1220, and a second elastic portion 1243 connecting the support portion 1241 to the mover 1230. The guide portion 1240 can be tilted relative to two axes using the first elastic portion 1242 and the second elastic portion 1243. In an embodiment, the guide portion 1240 can be rotated relative to a first direction (X-axis direction) using the first elastic portion 1242 (to correspond to tilting along the second axis). Furthermore, the guide portion 1240 can be rotated relative to a second direction (Y-axis direction) using the second elastic portion 1243 (to correspond to tilting along the first axis). Additionally, the drive portion 1250 includes a drive magnet 1251, a drive coil 1252, a Hall sensor portion 1253, a coupling portion 1254, and a substrate portion 1255. Each component will be described below.

[0141] The protective cover 1210 may be positioned in a region of the second camera actuator 1200 (e.g., at the outermost point) to surround the guide portion 1240 and the drive portion 1250, which will be described below.

[0142] The protective cover 1210 can block or reduce electromagnetic waves generated from the outside. Therefore, it can reduce the occurrence of malfunctions in the guide section 1240 or the drive section 1250.

[0143] The housing 1220 can be disposed within the protective cover 1210. Furthermore, the housing 1220 can be positioned inside the base plate portion 1255. The housing 1220 can be secured to the protective cover 1210 by being inserted into or aligned with it.

[0144] The housing 1220 may include a plurality of housing sides. In an embodiment, the housing 1220 may include a first housing side to a fifth housing side. Details thereto will be described below.

[0145] The housing 1220 may include a receiving portion 1226, which is a cavity between a plurality of housing sides.

[0146] The mover 1230 includes a retainer 1231 and an optical component 1232 disposed on the retainer 1231.

[0147] The retainer 1231 can be housed in the receiving portion 1226 of the housing 1220. The retainer 1231 may include a first retainer outer surface to a fourth retainer outer surface corresponding to the first housing side, the second housing side, the third housing side, and the fourth housing side, respectively. Details will be described below.

[0148] Optical component 1232 can be mounted on holder 1231. For this purpose, holder 1231 may include a mounting surface, and the mounting surface may be formed by a receiving portion. Optical component 1232 may include a reflective portion disposed therein. However, the invention is not limited thereto. Furthermore, optical component 1232 can reflect light reflected from the outside (e.g., an object) into the camera module. In other words, optical component 1232 can overcome the spatial limitations of the first and second camera actuators by changing the path of the reflected light. Therefore, it should be understood that the camera module can also provide a wide range of magnifications by increasing the optical path while minimizing thickness.

[0149] Optical component 1232 may include a reflecting component, such as a prism or mirror. The optical component may further include at least one lens in front of or behind the reflecting component.

[0150] The guide portion 1240 may be disposed within the housing 1220. Furthermore, as described above, the guide portion 1240 may utilize the first elastic portion 1242 and the second elastic portion 1243 to perform a first axis tilt and a second axis tilt on the mover 1230. Details will be described below.

[0151] 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.

[0152] The driving magnet 1251 may include multiple magnets. In an embodiment, the driving magnet 1251 may include a first magnet 1251a, a second magnet 1251b, and a third magnet 1251c.

[0153] The first magnet 1251a, the second magnet 1251b, and the third magnet 1251c can be positioned on the outer surface of the retainer 1231, respectively. Furthermore, the first magnet 1251a and the second magnet 1251b can be positioned facing each other. Additionally, the third magnet 1251c can be positioned on the bottom surface of the outer surface of the retainer 1231. Details will be described below.

[0154] The drive coil 1252 may include multiple coils. In an embodiment, the drive coil 1252 may include a first coil 1252a, a second coil 1252b, and a third coil 1252c.

[0155] The first coil 1252a can be positioned opposite the first magnet 1251a. Therefore, as described above, the first coil 1252a can be positioned in the first housing hole 1221a of the first housing side portion 1221.

[0156] Furthermore, the second coil 1252b can be positioned opposite the second magnet 1251b. Therefore, as described above, the second coil 1252b can be positioned in the second housing hole 1222a of the second housing side portion 1222.

[0157] The first coil 1252a can be positioned facing the second coil 1252b. That is, the first coil 1252a and the second coil 1252b can be symmetrically positioned relative to a first direction. This can be similarly applied to the first magnet 1251a and the second magnet 1251b. Due to this configuration, precise X-axis tilting can be performed without tilting to one side through 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.

[0158] The third coil 1252c can be positioned opposite the third magnet 1251c. Therefore, as described above, the third coil 1252c can be positioned in the third housing hole 1223a of the third housing side 1223. The third coil 1252c and the third magnet 1251c generate electromagnetic force to perform Y-axis tilting of the mover 1230 and the guide 1240 based on the housing 1220.

[0159] In this case, the X-axis tilt is a tilt relative to the X-axis (or a tilt relative to the reference axis serving as the X-axis), and the Y-axis tilt is a tilt relative to the Y-axis (or a tilt relative to the reference axis serving as the Y-axis). Furthermore, the first direction in the figures is the X-axis direction and can be used interchangeably with the first axis direction, first axis, etc. The second direction in the figures is the Y-axis direction and can be used interchangeably with the second axis direction, second axis, etc. The second direction is perpendicular to the first direction. Furthermore, the third direction in the figures is the Z-axis direction and can be used interchangeably with the third axis direction, etc. Furthermore, the third direction is perpendicular to both the first and second directions. In addition, in this invention, the first direction (X-axis direction) corresponds to the direction of the optical axis of light incident on the second camera actuator, and the second direction (Y-axis direction) and the third direction (Z-axis direction) are directions perpendicular to the optical axis and can be tilted by the second camera actuator. The third direction can correspond to the direction from the guide to the optical member or holder. Furthermore, the bottom surface refers to one side in the first direction, and within the housing, the third housing side can be the bottom surface, which can be inwardly directed toward the center of the camera actuator and outwardly directed toward the opposite direction. In this invention, the invention should be understood based on the above. However, since the second camera actuator allows light to pass through the optical components to the image sensor of the first camera actuator, the optical axis will be described based on the third direction, i.e., the Z-axis direction. In the first camera actuator described below, it should be understood that the optical axis can also be changed to the Z-axis. Furthermore, because the second camera actuator performs rotation relative to the first and second directions perpendicular to the third direction that serves as the optical axis, it is capable of performing OIS (Optical Image Switching) functions.

[0160] The Hall sensor unit 1253 may include multiple Hall sensors. In an embodiment, the Hall sensor unit 1253 may 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 may be positioned inside a first coil 1252a or a second coil 1252b. The first Hall sensor 1253a and the second Hall sensor 1253b can detect changes in magnetic flux inside the first coil 1252a or the second coil 1252b. Therefore, position sensing between the first magnet 1251a and the second magnet 1251b and the first Hall sensor 1253a and the second Hall sensor 1253b can be performed. A camera actuator according to an embodiment can use this to control X-axis tilt.

[0161] Furthermore, a third Hall sensor 1253c can be positioned inside the third coil 1252c. The third Hall sensor 1253c can detect changes in the magnetic flux inside the third coil 1252c. Therefore, position sensing between the third magnet 1251c and the third Hall sensor 1253c can be performed. A camera actuator according to an embodiment can use this to control Y-axis tilt.

[0162] The coupling portion 1254 may include a first coupling member 1254a, a second coupling member 1254b, and a third coupling member 1254c.

[0163] Each of the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be positioned in one of the placement grooves formed in the outer surface of the retainer 1231. Furthermore, the first coupling member 1254a and the second coupling member 1254b can be positioned facing each other. Additionally, the third coupling member 1254c can be positioned on the bottom surface (e.g., the outer surface of the third retainer) of the outer surface of the retainer 1231.

[0164] Furthermore, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can all be positioned between the first magnet 1251a to the third magnet 1251c and the retainer 1231.

[0165] The first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be yokes. Therefore, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be coupled to the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c, respectively.

[0166] Furthermore, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be respectively disposed in the first placement groove, the second placement groove, and the third placement groove, and can be easily coupled to the first placement groove, the second placement groove, and the third placement groove using an adhesive member injected through the groove formed in the first placement groove, the second placement groove, and the third placement groove.

[0167] Therefore, the first magnet 1251a, the second magnet 1251b and the third magnet 1251c can be easily coupled to the retainer 1231 via the first coupling member 1254a, the second coupling member 1254b and the third coupling member 1254c respectively.

[0168] Each of the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c can be positioned in one of the outer surfaces of the retainer 1231. Furthermore, the first magnet 1251a and the second magnet 1251b can be positioned facing each other. Additionally, the third magnet 1251c can be positioned on the bottom surface of one of the outer surfaces of the retainer 1231. Details will be described below.

[0169] The substrate portion 1255 can be positioned below the drive portion 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 coupled to the drive coil 1252 and the Hall sensor portion 1253 using surface mount technology (SMT). However, the present invention is not limited to this configuration.

[0170] The substrate portion 1255 can be positioned between the protective cover 1210 and the housing 1220 and coupled to the protective cover 1210 and the housing 1220. The coupling method can be performed differently as described above. Furthermore, through the above coupling, the drive coil 1252 and the Hall sensor portion 1253 can be positioned inside the outer surface of the housing 1220.

[0171] The substrate portion 1255 may include a circuit board having an electrically connectable wiring pattern, such as a rigid printed circuit board (rigid PCB), a flexible PCB, a rigid-flexible PCB, etc. However, the present invention is not limited to such types.

[0172] Figure 6a This is a perspective view of the housing according to an embodiment. Figure 6b This is a side view of the fourth housing side portion of the housing according to an embodiment, and... Figure 6c This is a side view of the fifth shell side shown in the figure. Figure 6d This is a side view of the first and second housing sides. Figure 6e This is a top view of the housing according to an embodiment, and Figure 6f This is a bottom view of the housing according to an embodiment.

[0173] refer to Figures 6a to 6f 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.

[0174] The first housing side portion 1221 and the second housing side portion 1222 can be arranged facing each other. In other words, the first housing side portion 1221 and the second housing side portion 1222 can be positioned corresponding to each other in a first direction. Furthermore, the third housing side portion 1223 can be provided on the bottom surface of the housing 1220. The fourth housing side portion 1224 and the fifth housing side portion 1225 can be arranged facing each other and disposed between the first housing side portion 1221 and the second housing side portion 1222. Furthermore, the fourth housing side portion 1224 and the fifth housing side portion 1225 can be positioned corresponding to each other in a first direction.

[0175] The third housing side 1223 can contact the first housing side 1221, the second housing side 1222, the fourth housing side 1224, and the fifth housing side 1225.

[0176] The first housing side portion 1221 may include a first housing hole 1221a. The first coil, which will be described below, may be positioned in the first housing hole 1221a.

[0177] The first housing side portion 1221 may include a first coupling protrusion (not shown). The first housing side portion 1221 may be easily coupled to the substrate portion using the first coupling protrusion (not shown).

[0178] Furthermore, the first housing side portion 1221 may include a first mounting protrusion 1221c. The first mounting protrusion 1221c may be positioned in the upper or lower portion of the first housing side portion 1221. The first mounting protrusion 1221c can easily support the substrate portion. Therefore, the coupling force between the first housing side portion and the substrate portion can be increased.

[0179] Furthermore, the second housing side portion 1222 may include a second housing hole 1222a. Additionally, the second coil, which will be described below, may be positioned within the second housing hole 1222a.

[0180] The first housing hole 1221a and the second housing hole 1222a can be positioned facing each other. For example, the first housing hole 1221a and the second housing hole 1222a can be symmetrically arranged with respect to a first direction (X-axis direction) or a third direction (Z-axis direction). Furthermore, the first coil and the second coil can be electrically connected and coupled to a substrate portion disposed outside the part 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 portion, and current can flow through it. This current is a component of electromagnetic force, through which the second camera actuator can perform tilting relative to the X-axis.

[0181] The second housing side portion 1222 may include a second coupling protrusion (not shown). The second housing side portion 1222 may be easily coupled to the substrate portion using the second coupling protrusion (not shown).

[0182] Furthermore, the second housing side portion 1222 may include a second mounting protrusion 1222c. The second mounting protrusion 1222c may be positioned in the upper or lower portion of the second housing side portion 1222. The second mounting protrusion 1222c can easily support the substrate portion. Therefore, the coupling force between the second housing side portion and the substrate portion can be increased.

[0183] Furthermore, the third housing side portion 1223 may include a third housing hole 1223a. A third coil, which will be described below, may be positioned in the third housing hole 1223a. The third coil may be coupled to the substrate portion. In an embodiment, the third coil may be electrically connected to the substrate portion 1255, and current may flow through it. This current is a component of an electromagnetic force, by which the second camera actuator can perform tilting relative to the Y-axis.

[0184] The third housing side portion 1223 may include a third coupling protrusion (not shown). The third housing side portion 1223 may be easily coupled to the substrate portion using the third coupling protrusion (not shown).

[0185] The fourth housing side 1224 can contact the first housing side 1221, the second housing side 1222, and the third housing side 1223. Specifically, the fourth housing side 1224 can be disposed on the third housing side 1223. The lower surface of the fourth housing side 1224 can contact one of the upper surfaces of the third housing side 1223, and the fourth housing side 1224 can be supported by the third housing side 1223. The fourth housing side 1224 may not be positioned in the optical path.

[0186] The fourth housing side portion 1224 may include a coupling hole CH. Therefore, the fourth housing side portion 1224 may include an inner surface CHS of the coupling hole CH. In addition, the fourth housing side portion 1224 may include a protrusion CHP positioned on the inner surface CHS.

[0187] The protrusion CHP can be positioned on the bisector of the fourth housing side 1224 in the second direction (Y-axis direction). Furthermore, the coupling hole CH can be positioned corresponding to the first support portion of the support portion, which will be described below. In an embodiment, the coupling hole CH can overlap with the first support portion of the support portion in the third direction (Z-axis direction).

[0188] Furthermore, the first support portion can be disposed in the coupling hole CH. Therefore, the first support portion and the fourth housing side portion 1224 can be coupled to each other.

[0189] In the coupling hole CH, the protrusion CHP can be positioned on one of the surfaces CHS facing in the second direction (Y-axis direction). That is, compared with the case where the protrusion CHP is positioned on the surface CHS' facing in the first direction (X-axis direction) in the coupling hole CH, the first support can be easily inserted into the coupling hole CH and coupled to the coupling hole CH.

[0190] The fifth housing side 1225 may be configured to face the fourth housing side 1224. The fifth housing side 1225 may include an opening 1225a. Therefore, light passing through or reflected by the optical component can move through the opening 1225a.

[0191] Furthermore, the fifth housing side portion 1225 may include a housing protrusion 1225b. The housing protrusion 1225b may protrude outwards. The housing 1220 can be coupled to a first camera actuator disposed externally using the housing protrusion 1225b. Therefore, the reliability of the camera module can be improved.

[0192] Furthermore, the fifth housing side portion 1225 may include a protrusion 1225b and a patterned portion (not shown) having a pattern surrounding the housing protrusion 1225b. The patterned portion (not shown) may be positioned further inwardly stepped than the housing protrusion 1225b. That is, the patterned portion (not shown) may be positioned further inwardly than the housing protrusion 1225b.

[0193] An adhesive member can be applied to the patterned portion (not shown). Therefore, the contact area between the adhesive member and the fifth housing side portion 1225 can be increased on the patterned portion (not shown). Consequently, the coupling force between the second actuator (or housing 1220) and the first actuator can be increased.

[0194] Furthermore, the housing 1220 may include a receiving portion 1226 formed therein by the first housing side portion 1221 to the fifth housing side portion 1225. The mover 1230 and the guide portion 1240 may be positioned in the receiving portion 1226.

[0195] Figure 7a This is a perspective view of the mobile device according to an embodiment, and Figure 7b This is a perspective view illustrating a retainer according to an embodiment. Figure 7c The illustration is a side view of the mobile device according to an embodiment, and Figure 7d This is a bottom view of the mobile device according to an embodiment.

[0196] refer to Figures 7a to 7d The mover 1230 according to the embodiment may include a retainer 1231 and an optical component 1232 disposed on the retainer 1231.

[0197] First, the optical component 1232 can be mounted on the holder 1231. The optical component 1232 can be a prism, a mirror, etc., as described above, but is not limited to these.

[0198] Furthermore, the retainer 1231 may include a mounting surface 1231k on which the optical member 1232 is mounted. The mounting surface 1231k may be an inclined surface. Additionally, the retainer 1231 may include a jaw portion SP at its lower portion. The jaw portion SP in the retainer 1231 can prevent movement of the optical member 1232. Therefore, light incident from the upper portion can pass through the optical member 1232 and the opening on the side of the fifth housing and move in the third direction (Z-axis direction).

[0199] In addition, the retainer 1231 may include a plurality of outer surfaces. For example, the retainer 1231 may include a first retainer outer surface 1231S1, a second retainer outer surface 1231S2, a third retainer outer surface 1231S3, and a fourth retainer outer surface 1231S4.

[0200] The outer surface 1231S1 of the first retainer can be positioned to face the outer surface 1231S2 of the second retainer. That is, the outer surface 1231S1 of the first retainer and the outer surface 1231S2 of the second retainer can be symmetrically arranged with respect to the first direction (X-axis direction).

[0201] The outer surface 1231S1 of the first retainer can be positioned to face the side 1221 of the first housing. Furthermore, the outer surface 1231S2 of the second retainer can be positioned to face the side 1222 of the second housing.

[0202] Additionally, the outer surface 1231S1 of the first retainer may include a first mounting groove 1231S1a. Furthermore, the outer surface 1231S2 of the second retainer may include a second mounting groove 1231S2a. The first mounting groove 1231S1a and the second mounting groove 1231S2a may be symmetrically arranged relative to a first direction (X-axis direction).

[0203] Furthermore, the first coupling member and the first magnet, as described below, can be disposed in the first mounting groove 1231S1a, and the second coupling member and the second magnet 1251b can be disposed in the second mounting groove 1231S2a. The first magnet and the second magnet can also be symmetrically arranged relative to the first direction (X-axis direction). Furthermore, the first coupling member and the second coupling member can also be symmetrically arranged relative to the first direction (X-axis direction).

[0204] Furthermore, the first magnet and the second magnet can overlap in the second direction, and the first coupling member and the second coupling member can also overlap in the second direction. As described above, due to the positions of the first and second mounting slots and the first and second magnets, the electromagnetic force induced by the magnets can be coaxially provided to the outer surfaces 1231S1 and 1231S2 of the first holder. For example, the region of the outer surface S1231S1 of the first holder on which the electromagnetic force is applied (e.g., the part where the electromagnetic force is strongest) and the region of the outer surface S1231S1 of the second holder on which the electromagnetic force is applied (e.g., the part where the electromagnetic force is strongest) can be positioned on an axis parallel to the second direction (Y-axis direction). Therefore, X-axis tilting can be performed precisely.

[0205] Furthermore, the outer surfaces 1231S1 and 1231S2 of the first and second retainers may additionally include grooves (not shown). Due to these grooves (not shown), the weight of the retainer 1231 is reduced, and therefore, energy consumption can be minimized when performing one-axis or two-axis tilting. That is, the amount of current applied to the first, second, and third coils can be minimized, and correspondingly, energy efficiency can be improved. Furthermore, the aforementioned grooves (not shown) can be symmetrically arranged relative to the first direction (X-axis direction). Therefore, the center of gravity of the retainer 1231 is prevented from shifting to one side, and tilting can thus be performed with a uniform force.

[0206] The third retainer outer surface 1231S3 may be an outer surface that contacts the first retainer outer surface 1231S1 and the second retainer outer surface 1231S2 and extends between the first retainer outer surface 1231S1 and the second retainer outer surface 1231S2 in a second direction (Y-axis direction). Therefore, the third retainer outer surface 1231S3 may be positioned between the first retainer outer surface 1231S1 and the second retainer outer surface 1231S2.

[0207] Furthermore, the outer surface 1231S3 of the third retainer can be the bottom surface of the retainer 1231. The outer surface 1231S3 of the third retainer can be positioned to face the side portion 1223 of the third housing. Furthermore, the outer surface 1231S3 of the third retainer can contact the side portion 1223 of the third housing.

[0208] Furthermore, the outer surface 1231S3 of the third holder may include a third mounting groove 1231S3a. A third magnet 1251c may be disposed in the third mounting groove 1231S3a. Additionally, at least a portion of the third housing hole 1223a may overlap the third mounting groove 1231S3a in a first direction (X-axis direction). Therefore, the third magnet 1251c in the third mounting groove 1231S3a and the third coil 1252c in the third housing hole 1223a may be positioned facing each other. Furthermore, the third magnet 1251c and the third coil 1252c generate electromagnetic force, and thus the camera actuator can perform Y-axis tilting.

[0209] Furthermore, although X-axis tilting is performed by multiple magnets (first magnet 1251a and second magnet 1251b), Y-axis tilting can be performed by only the third magnet 1251c. In an embodiment, the area of ​​the third mounting slot 1231S3a may differ from the area of ​​the first mounting slot 1231S1a or the second mounting slot 1231S2a. For example, the area of ​​the third mounting slot 1231S3a may be larger than the area of ​​the first mounting slot 1231S1a or the second mounting slot 1231S2a. Due to this configuration, Y-axis tilting can be performed by current control similar to the current control used to perform X-axis tilting.

[0210] The outer surface 1231S3 of the third retainer may additionally include a groove 1231S3b. Due to the groove 1231S3b, the weight of the retainer 1231 is reduced, and therefore, energy consumption can be minimized when performing one-axis tilting or two-axis tilting. That is, the amount of current applied to the first coil, the second coil, and the third coil can be minimized, and correspondingly, energy efficiency can be improved.

[0211] Furthermore, additional grooves 1231S3b can be provided as a plurality of grooves 1231S3b in the outer surface 1231S3 of the third retainer, and when a plurality of grooves 1231S3b are present, the plurality of grooves 1231S3b can be symmetrically arranged relative to the first direction (X-axis direction).

[0212] The fourth retainer outer surface 1231S4 may be an outer surface that contacts the first retainer outer surface 1231S1 and the second retainer outer surface 1231S2 and extends from the third retainer outer surface 1231S1 in a first direction (X-axis direction). Furthermore, the fourth retainer outer surface 1231S4 may be positioned between the first retainer outer surface 1231S1 and the second retainer outer surface 1231S2.

Figure 8k This is a perspective view of the guide portion according to another embodiment.

[0214] First, refer to Figure 8a According to an embodiment, the guide portion 1240 may include a support portion 1241, a first elastic portion 1242, and a second elastic portion 1243. The positions of the first elastic portion 1242 and the second elastic portion 1243 may be changed, and the invention will be described based on the accompanying drawings in this specification.

[0215] According to the embodiment, the support portion 1241 can be coupled to the mover and the housing using a first elastic portion and a second elastic portion. Furthermore, the support portion 1241 can move relative to a first direction (X-axis direction). However, the support portion 1241 does not move relative to a second direction (Y-axis direction). Details will be described below.

[0216] Furthermore, the first elastic portion 1242 can be disposed between the support portion 1241 and the mover, and can connect the support portion 1241 and the mover. The first elastic portion 1242 can be disposed in a first direction (X-axis direction) and can include a first pattern positioned between the first support portion and the coupling hole. The first elastic portion 1242 can perform second axis tilting (or movement in a second direction) based on the first pattern.

[0217] Furthermore, a second elastic portion 1243 may be disposed between the support portion 1241 and the housing, and may connect the support portion 1241 and the housing. The second elastic portion 1243 may include a second pattern disposed in a second direction (Y-axis direction). The second elastic portion 1243 may perform a first axis tilt (or movement in the first direction) based on the second pattern. Details will be described below.

[0218] In an embodiment, the first elastic portion 1242 may be disposed in a direction perpendicular to the second elastic portion 1243.

[0219] refer to Figures 8b to 8dAccording to the embodiment, the support portion 1241 can be configured to be separate from the mover and the housing in a third direction (Z-axis direction). Therefore, the support portion 1241 can be used to perform two-axis tilting at a desired angle.

[0220] In addition, 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).

[0221] The first support portion SA1 can extend in a first direction (X-axis direction). For example, in the first support portion SA1, in the XY plane, the length in the first direction (X-axis direction) can be greater than the length in the second direction (Y-axis direction).

[0222] The second support portion SA2 can extend in a second direction (Y-axis direction). For example, in the second support portion SA2, in the XY plane, the length in the second direction (Y-axis direction) can be greater than the length in the first direction (X-axis direction).

[0223] In an embodiment, the length L2 of the first support portion SA1 in the second direction (Y-axis direction) may be less than the length L1 of the second support portion SA2 in the second direction (Y-axis direction).

[0224] The first support portion SA1 can be positioned on the second support portion SA2. In other words, the second support portion SA2 can be positioned below the first support portion SA1. Furthermore, the first support portion SA1 can be supported by the second support portion SA2. According to the embodiment, the first support portion SA1 and the second support portion SA2 can be coupled to each other. For example, the first support portion SA1 and the second support portion SA2 can be integrally formed.

[0225] The first support portion SA1 can be positioned in the second direction (Y-axis direction) without overlapping the virtual line IV1 that divides the mover or the second support portion SA2 equally. In other words, the first support portion SA1 can be configured to be separate from the virtual line IV1 in the second direction (Y-axis direction). Alternatively, the first support portion SA1 can be configured to be displaced from the virtual line IV1 in the second direction (Y-axis direction).

[0226] The first support portion SA1 can contact the upper surface SA2u of the second support portion SA2. Furthermore, the first support portion SA1 may include a first coupling protrusion PP1 disposed on a side surface SA1s. At least a portion of the first coupling protrusion PP1 may overlap the aforementioned dashed line IV1 in a third direction (Z-axis direction). Due to this configuration, the first elastic portion can be coupled to the support portion 1241 using the first coupling protrusion PP1 and rotate simultaneously.

[0227] The first coupling protrusion PP1 can be coupled to the first elastic portion, which will be described below. In an embodiment, the first coupling protrusion PP1 can contact a side surface SA1s and an upper surface SA2u of the second support portion SA2.

[0228] The first coupling protrusion PP1 can be positioned on a bisector or region of a side surface SA1s of the first support portion SA1 in the third direction (Z-axis direction). Therefore, the supporting force of the first coupling protrusion PP1 for the first elastic portion can be applied evenly to the support portion, that is, the phenomenon of the supporting force being concentrated on one side of the support portion can be prevented.

[0229] As described above, the second support SA2 can be connected to the first support SA1 and the first coupling protrusion PP1 on the upper surface SA2u.

[0230] Furthermore, the second support portion SA2 may include a second coupling protrusion PP2 disposed on the lower surface SA2b. The second coupling protrusion PP2 may protrude downward from the lower surface SA2b of the second support portion SA2. Additionally, the second coupling protrusion PP2 may be coupled to a coupling hole in the second elastic portion, which will be described below. Therefore, the second elastic portion may be positioned below the support portion 1241 and the locator to easily support the locator and the support portion 1241.

[0231] Furthermore, the second coupling protrusion PP2 can be provided as one or more second coupling protrusions PP2. Moreover, the second coupling protrusions PP2 can be symmetrically arranged relative to the first direction (X-axis direction). Due to this configuration, the coupling force between the support portion 1241 and the mover can be prevented from being concentrated on one side of the second support portion SA2 by the second elastic portion.

[0232] Furthermore, the second coupling protrusion PP2 can be positioned in the central portion of the second support SA2 in the third direction (Z-axis direction). Due to this configuration, force can be uniformly applied to the support 1241 through the second coupling protrusion PP2.

[0233] Furthermore, according to the embodiment, as described above, the first elastic portion 1242 can be coupled to a side surface of the support portion, specifically, to a side surface SA1s of the first support portion. Additionally, the first elastic portion can be coupled to the lower surface of the mobilizer.

[0234] Furthermore, the second elastic portion 1243 can be coupled to the lower surface of the support portion, specifically, to the lower surface SA2b of the second support portion SA2. Additionally, the second elastic portion 1243 can be coupled to the housing.

[0235] Furthermore, a side surface of the first support portion SA1S and the lower surface SA2b of the second support portion SA2 can be perpendicular to each other. Therefore, the first elastic portion and the second elastic portion can tilt relative to each other in a direction perpendicular to each other, and ultimately, the mover can tilt relative to the two axes.

[0236] refer to Figure 8e and Figure 8f As described above, the first elastic portion 1242 according to the embodiment can be coupled to the first support portion SA1. The length of the first elastic portion 1242 in the first direction (X-axis direction) can be greater than its length in the second direction (Y-axis direction). Furthermore, at least a portion of the first elastic portion 1242 can overlap the aforementioned virtual line IV1 (see...). Figure 8c Therefore, in the first elastic part 1242, the 1-1 coupling region 1242b, which will be described below, can rotate or move relative to the first direction (X-axis direction) or the virtual line. Thus, the support portion connected to the first elastic part 1242, the second elastic part, and the mover can move in response to the movement of the 1-1 coupling region 1242b.

[0237] First, the first elastic portion 1242 may include a first pattern PT1 disposed in a first direction (X-axis direction). The first pattern PT1 may be a groove or a hole. Hereinafter, the first pattern PT1 will be described based on the hole in the accompanying drawings. The first pattern 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 in the first direction (X-axis direction).

[0238] The first pattern PT1 can be symmetrically arranged relative to the second direction (Y-axis direction). Therefore, the reliability of the first elastic part 1242 can be improved even during rotation through the first pattern PT1.

[0239] The first elastic portion 1242 may have a first pattern region 1242a, a 1-1 coupling region 1242b, and a 1-2 coupling region 1242c formed in a third direction (Z-axis direction).

[0240] The first pattern region 1242a may be a region in which the first pattern PT1 is disposed. The first pattern region 1242A may be a region extending in a first direction (X-axis direction) and corresponding to the first pattern PT1.

[0241] Furthermore, the 1-1 coupling region 1242b and the 1-2 coupling region 1242c can be partitioned by the first pattern region 1242a.

[0242] The 1-1 coupling region 1242b can be positioned between the first pattern region 1242a and the mover. In other words, the 1-1 coupling region 1242b can be coupled to the first support.

[0243] The 1-2 coupling region 1242c can be positioned between the first patterned region 1242a and the housing (e.g., the fourth housing side). In other words, the 1-2 coupling region 1242c can be positioned in the coupling hole of the fourth housing side.

[0244] Because the first pattern region 1242A includes the first pattern PT1, the rigidity of the first pattern region 1242A can be less than the rigidity of each of the 1-1 coupling regions 1242b and 1-2 coupling regions 1242c. Therefore, the 1-1 coupling regions 1242b and 1-2 coupling regions 1242c can be folded along the first pattern region 1242a. That is, the 1-1 coupling regions 1242b and 1-2 coupling regions 1242c can be moved.

[0245] Furthermore, in the first pattern region 1242a, the hole as the first pattern PT1 is provided in the first direction (X-axis direction), and therefore the 1-1 coupling region 1242b and the 1-2 coupling region 1242c can rotate relative to the first direction (X-axis direction).

[0246] The 1-1 coupling region 1242b can be coupled to the first support portion. The 1-1 coupling region 1242b may include a 1-1 elastic hole 1242h1 and a 1-1 elastic groove 1242p1.

[0247] The 1-1 elastic hole 1242h1 can be configured to be separate from the 1-1 elastic groove 1242p1 in the 1-1 coupling region 1242b. An adhesive member can be applied to the 1-1 elastic hole 1242h1. Furthermore, the 1-1 coupling region 1242b can be coupled to the support via the adhesive member.

[0248] Furthermore, the 1-1 elastic groove 1242p1 can be positioned at the lower part of the 1-1 coupling region 1242b. Therefore, the lower part of the 1-1 coupling region 1242b can be opened due to the 1-1 elastic groove 1242p1. This facilitates the manufacturing of the 1-1 coupling region 1242b, and the 1-1 coupling region 1242b and the support can be easily coupled simultaneously. For example, the 1-1 coupling region 1242b and the support can be coupled by insertion. Furthermore, a downward load is applied, thus increasing the coupling force between the components.

[0249] Adhesive components can be applied in the elastic groove 1-1242p1.

[0250] The 1-2 coupling region 1242c can be coupled to the protrusion of the coupling hole on the side of the fourth housing. The 1-2 coupling region 1242c may include 1-2 elastic holes 1242h2 and 1-2 elastic grooves 1242p2.

[0251] The 1-2 elastic holes 1242h2 can be configured to be separate from the 1-2 elastic grooves 1242p2 in the 1-2 coupling region 1242c. An adhesive member can be disposed in the 1-2 elastic holes 1242h2. Furthermore, the 1-2 coupling region 1242c can be coupled to the fourth housing side via the adhesive member.

[0252] Furthermore, the 1-2 resilient grooves 1242p2 can be positioned in the lower part of the 1-2 coupling regions 1242c. Therefore, the lower part of the 1-2 coupling regions 1242c may be opened due to the 1-2 resilient grooves 1242p2. This facilitates the manufacturing of the 1-2 coupling regions 1242c and allows for easy coupling of both the 1-2 coupling regions 1242c and the support portion. For example, the 1-2 coupling regions 1242c and the support portion can be coupled by insertion. Furthermore, a downward load is applied, thus increasing the coupling force between the components. Additionally, adhesive members can be applied in the 1-2 resilient grooves 1242p2.

[0253] refer to Figures 8g to 8h As described above, the second elastic portion 1243 according to the embodiment can be coupled to the second support portion SA2. The length of the second elastic portion 1243 in the second direction (Y-axis direction) can be greater than its length in the first direction (X-axis direction).

[0254] The second elastic section 1243 can be equally divided by the aforementioned virtual line IV1 (see...). Figure 8c In other words, the bisector of the second elastic part 1243 in the second direction (Y-axis direction) can correspond to the aforementioned virtual line.

[0255] Furthermore, in the second elastic portion 1243, the 2-1 coupling region 1243b, which will be described below, can rotate or move relative to the second direction (Y-axis direction). Therefore, the locator connected to the second elastic portion 1243 can move in response to the movement of the 2-2 coupling region 1243c.

[0256] First, the second elastic portion 1243 may include a second pattern PT2 disposed in the second direction (Y-axis direction). The second pattern PT2 may be a groove or a hole. Hereinafter, the second pattern PT2 will be described based on the hole as shown in the accompanying drawings. The second pattern 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 in the second direction (Y-axis direction). The second pattern PT2 may be positioned between the lower surface of the mover and the second support portion.

[0257] The second pattern PT2 can be symmetrically arranged relative to the first direction (X-axis direction). Therefore, when rotation is performed through the second pattern PT2, the load applied to the second elastic part 1243 is uniform, and thus the reliability of the second elastic part 1243 can be improved.

[0258] The second elastic portion 1243 may have a second pattern region 1243a, a 2-1 coupling region 1243b, and a 2-2 coupling region 1243c formed in a third direction (Z-axis direction).

[0259] The second pattern region 1243A may be a region in which the second pattern PT2 is disposed. The second pattern region 1243a may be a region extending in the second direction (Y-axis direction) and corresponding to the second pattern PT2.

[0260] Furthermore, the 2-1 coupling region 1243b and the 2-2 coupling region 1243c can be partitioned by the second patterned region 1243a. First, the 2-1 coupling region 1243b can be positioned between the second patterned region 1243a and the fourth housing side. In other words, the 2-1 coupling region 1243b can be coupled to the second support portion.

[0261] The 2-2 coupling region 1243c can be positioned between the second pattern region 1243a and the mover. In other words, the 2-2 coupling region 1243c can be positioned between the fifth housing side and the mover.

[0262] Because the second pattern region 1243A includes the second pattern PT2, the rigidity of the second pattern region 1243A can be less than the rigidity of each of the 2-1 coupling regions 1243b and 2-2 coupling regions 1243c. Therefore, the 2-1 coupling regions 1243b and 2-2 coupling regions 1243c can be folded along the first pattern region 1243a. That is, the 2-1 coupling regions 1243b and 2-2 coupling regions 1243c can be moved.

[0263] Furthermore, in the second pattern region 1243A, the hole as the second pattern PT2 is provided in the first direction (X-axis direction), and therefore the 2-1 coupling region 1243b and the 2-2 coupling region 1243c can rotate relative to the second direction (Y-axis direction).

[0264] 2-1 The coupling region 1243b can be coupled to the second support. 2-1 The coupling region 1243b may include 2-1 the elastic hole 1243h1.

[0265] The 2-1 elastic hole 1243h1 can be coupled to the aforementioned second coupling protrusion PP2. That is, the 2-1 elastic hole 1243h1 can be positioned to correspond to the second coupling protrusion PP2. Therefore, the 2-1 elastic hole 1243h1 can be symmetrically positioned relative to either the first direction (X-axis direction) or the third direction (Z-axis direction). An adhesive member can be applied to the 2-1 elastic hole 1243h1. Furthermore, the 2-1 coupling region 1243b can be coupled to the second support portion via an adhesive member.

[0266] The 2-2 coupling region 1243c can be coupled to the lower surface of the mover. The 2-2 coupling region 1243c may include the 2-2 elastic hole 1243h2, the 2-3 elastic hole 1243h3, and the 2-4 elastic hole 1243h4.

[0267] In the 2-2 coupling region 1243c, the 2-2 elastic hole 1243h2 can be coupled to the locator protrusion at the lower part of the locator. An adhesive member can be applied to the 2-2 elastic hole 1243h2. Furthermore, the 2-2 coupling region 1243c can be coupled to the locator via an adhesive member.

[0268] The 2-3 resilient hole 1243h3 can be positioned to correspond to the third mounting slot in the lower part of the mover. Furthermore, the 2-3 resilient hole 1243h3 can be positioned to correspond to the third magnet in the third mounting slot. Due to this configuration, the 2-3 resilient hole 1243h3 can prevent a reduction in the electromagnetic force generated between the third magnet and the third coil.

[0269] Furthermore, the 2-4 elastic holes 1243h4 can simultaneously reduce the weight of the second elastic part 1243 and the influence of the first and second magnets disposed in the first and second mounting slots. That is, the 2-4 elastic holes 1243h4 can prevent the generation of magnetic forces between the second elastic part 1243 and the first or second magnet. Therefore, more precise and effective biaxial tilting can be performed.

[0270] Furthermore, the length L4 of the 2-1 coupling region 1243b in the third direction (Z-axis direction) can be less than the length L3 of the 2-2 coupling region 1243c in the third direction (Z-axis direction). Therefore, the second elastic part 1243 can easily support the load of the mover through the 2-2 coupling region 1243c.

[0271] refer to Figure 8iAs described above, the rigidity of the second patterned region 1243a of the second elastic portion 1243 is less than the rigidity of each of the other regions 1243b and 1243c, and therefore the first axis tilt can be performed based on the second patterned region 1243a. That is, the first axis tilt of the 2-2 coupling region 1243c of the second elastic portion 1243 can be performed, and the first axis tilt of the mover disposed on the 2-2 coupling region 1243c can also be performed.

[0272] refer to Figure 8j As described above, the rigidity of the first patterned region 1242a of the first elastic portion 1242 is less than the rigidity of each of the other regions 1242b and 1242c, and a second axis tilt can be performed based on the first patterned region 1242a. That is, a second axis tilt can be performed on the 1-1 coupling region 1242b of the first elastic portion 1242, and a first axis tilt can also be performed on the mover disposed on the 1-1 coupling region 1242b.

[0273] refer to Figure 8k In the support portion 1241' of the guide portion 1240 according to another embodiment, a plurality of first support portions SA1a and SA1b may be provided. That is, the plurality of first support portions SA1a and SA1b may be configured to face each other based on the aforementioned virtual line.

[0274] Therefore, the coupling force between the first elastic part 1242 and the first support parts SA1a and SA1b can be increased. Therefore, even when the first elastic part 1242 is tilted more than the second elastic part 1243, two-axis tilting can be easily performed.

[0275] Figure 9 This is a view of the drive unit according to an embodiment.

[0276] refer to Figure 9 As described 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.

[0277] Furthermore, as described above, the driving magnet 1251 may include a first magnet 1251a, a second magnet 1251b, and a third magnet 1251c that provide driving force via electromagnetic force. Each of the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c may be positioned in one of the outer surfaces of the retainer 1231.

[0278] Furthermore, the drive coil 1252 may include multiple coils. In an embodiment, the drive coil 1252 may include a first coil 1252a, a second coil 1252b, and a third coil 1252c.

[0279] The first coil 1252a can be positioned opposite the first magnet 1251a. Therefore, as described above, the first coil 1252a can be positioned in the first housing hole 1221a of the first housing side 1221. Furthermore, the second coil 1252b can be positioned opposite the second magnet 1251b. Therefore, as described above, the second coil 1252b can be positioned in the second housing hole 1222a of the second housing side 1222.

[0280] When OIS is implemented by controlling the mover 1230 to rotate in a first direction (X-axis direction) or a second direction (Y-axis direction) using the electromagnetic force between the drive magnet 1251 and the drive coil 1252, the second camera actuator according to the embodiment is able to minimize the occurrence of downsloping or tilting phenomena to provide optimal optical properties.

[0281] Furthermore, according to the embodiment, since OIS is achieved using a guide portion 1240 disposed between the housing 1220 and the mover 1230, the size limitation of the actuator is resolved, and thus it is possible to provide an ultra-thin and ultra-small camera actuator and a camera module including the camera actuator.

[0282] The coupling portion 1254 may include a first coupling member 1254a, a second coupling member 1254b, and a third coupling member 1254c.

[0283] Furthermore, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can all be positioned between the first magnet 1251a to the third magnet 1251c and the retainer 1231.

[0284] The first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be yokes. Therefore, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be coupled to the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c, respectively.

[0285] Furthermore, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be respectively disposed in the first placement groove, the second placement groove, and the third placement groove, and can be easily coupled to the first placement groove, the second placement groove, and the third placement groove respectively by an adhesive member injected through the groove formed in the first placement groove, the second placement groove, and the third placement groove.

[0286] 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.

[0287] The first substrate side portion 1255a and the second substrate side portion 1255b can be configured to face each other. Furthermore, the third substrate side portion 1255c can be positioned between the first substrate side portion 1255a and the second substrate side portion 1255b.

[0288] Furthermore, the first substrate side portion 1255a can be positioned between the first housing side portion and the protective cover, and the second substrate side portion 1255b can be positioned between the second housing side portion and the protective cover. Additionally, the third substrate side portion 1255c can be positioned between the third housing side portion and the protective cover and can be the bottom surface of the substrate portion 1255.

[0289] The first substrate side portion 1255a can be coupled and electrically connected to the first coil 1252a. Furthermore, the first substrate side portion 1255a can be coupled and electrically connected to the first Hall sensor 1253a.

[0290] The second substrate side portion 1255b can be coupled and electrically connected to the second coil 1252b. Furthermore, it should be understood that the second substrate side portion 1255b can also be coupled and electrically connected to the second Hall sensor 1253b.

[0291] Furthermore, the first substrate side portion 1255a and the second substrate side portion 1255b can extend in the third direction (Z-axis direction). Therefore, the first substrate side portion 1255a and the second substrate side portion 1255b can have a region extending from the fifth housing side portion in the third direction (Z-axis direction).

[0292] Furthermore, the third substrate side portion 1255c can be coupled and electrically connected to the third coil 1252c. Additionally, the third substrate side portion 1255c can be coupled and electrically connected to the third Hall sensor 1253c.

[0293] Figure 10 This is a perspective view illustrating the state in which the protective cover and substrate are removed from the second camera actuator according to an embodiment. Figure 11a It is along Figure 10 A cross-sectional view of line BB' in the diagram. Figure 11b It is along Figure 10 The cross-sectional view of line CC' in the diagram, and Figure 11c It is along Figure 10 The cross-sectional view of line DD' in the diagram.

[0294] refer to Figure 10 and 11a Up to 11c, the first coil 1252a can be positioned on the first housing side 1221, and the first magnet 1251a and the first coupling member 1254a can be positioned on the first retainer outer surface 1231S1 of the retainer 1231.

[0295] Furthermore, the first coil 1252a and the first magnet 1251a can be positioned relative to each other. At least a portion of the first magnet 1251a can overlap the first coil 1252a in the second direction (Y-axis direction). Additionally, at least a portion of the first coupling member 1254a can overlap the first coil 1252a in the second direction (Y-axis direction).

[0296] Furthermore, the second coil 1252b can be positioned on the second housing side 1222, and the second magnet 1251b and the second coupling member 1254b can be positioned on the second retainer outer surface 1231S2 of the retainer 1231. Therefore, the second coil 1252b and the second magnet 1251b can be positioned opposite each other. At least a portion of the second magnet 1251b can overlap the second coil 1252b in the second direction (Y-axis direction). Similarly, at least a portion of the second coupling member 1254b can overlap the second coil 1252b in the second direction (Y-axis direction).

[0297] Furthermore, the first coil 1252a and the second coil 1252b can overlap in the second direction (Y-axis direction), and the first magnet 1251a and the second magnet 1251b can overlap in the second direction (Y-axis direction). With this configuration, the electromagnetic force applied to the outer surfaces of the retainer (the outer surfaces of the first and second retainers) is positioned along an axis parallel to the second direction (Y-axis direction), and thus X-axis tilting can be performed precisely and accurately.

[0298] Furthermore, as described above, the first Hall sensor 1253a and the second Hall sensor 1253b can be positioned externally for electrical connection and coupling to the substrate portion 1255. However, the positions of the first Hall sensor 1253a and the second Hall sensor 1253b are not limited thereto.

[0299] Furthermore, the third coil 1252c can be positioned on the third housing side 1223, and the third magnet 1251c can be positioned on the third retainer outer surface 1231S3 of the retainer 1231. At least a portion of the third coil 1252c and the third magnet 1251c can overlap in the first direction (X-axis direction). Therefore, the magnitude of the electromagnetic force between the third coil 1252c and the third magnet 1251c can be easily controlled.

[0300] As described above, the guide portion 1240 can be positioned between the retainer 1231 and the fourth housing side portion 1224.

[0301] Furthermore, at least a portion of the first elastic portion 1242 may be configured to overlap with lines that divide the mover 1230 equally in the second direction (Y-axis direction). That is, the first elastic portion 1242 may be positioned in the central portion of the retainer 1231 of the mover 1230.

[0302] Therefore, in the first elastic part 1242, the support part coupled to the 1-1 coupling region can move in the second direction (Y-axis direction) based on the first pattern region in which the first pattern PT1 is positioned, or can perform its first axis tilt.

[0303] In the guide portion 1240, the first elastic portion 1242 can be coupled to a protrusion CHP positioned on one surface of the coupling hole CH of the housing 1220. In the first elastic portion 1242, the elastic groove 1242p1 and the protrusion CHP positioned in the 1-2 coupling region can be coupled to each other.

[0304] Furthermore, the 1-2 elastic groove 1242p2 located in the 1-1 coupling region can be coupled to the first coupling protrusion PP1 of the support portion 1241. Therefore, the housing 1220, the first elastic portion 1242, and the support portion 1241 can be coupled to each other. Additionally, the support portion 1241 can be coupled to the second coupling protrusion PP2 of the support portion 1241 via the second elastic portion 1243. Furthermore, the second elastic portion 1243 can be coupled to the mover protrusion of the mover via the 2-2 coupling region. Therefore, all of the housing 1220, the guide portion 1240, and the mover 1230 can be coupled, and the tilting of the two axes of the mover can be performed by the first elastic portion 1241 and the second elastic portion 1242.

[0305] Furthermore, the lower surfaces of the 1-1 elastic groove 1242p1 and the 1-2 elastic groove 1242p2 can be coplanar.

[0306] Furthermore, the 1-2 elastic holes 1242h2 and the 1-1 elastic hole 1242h1 can be arranged side by side in the third direction (Z-axis direction). Therefore, the coupling force can be further increased.

[0307] Figure 12 The diagram is in Figure 11a An exemplary view of the movement of the second camera actuator illustrated in the figure, and Figure 13 The diagram is in Figure 11b and Figure 11c An exemplary view of the movement of the second camera actuator is shown in the figure.

[0308] refer to Figure 12 It can perform Y-axis tilting. That is, rotation can be performed in the first direction (X-axis direction) to implement OIS.

[0309] In this embodiment, the third magnet 1251c and the third coil 1252c disposed in the lower part of the retainer 1231 can generate an electromagnetic force to tilt or rotate the mover 1230 in a first direction (X-axis direction). That is, by means of the electromagnetic force, the retainer 1231 and the second elastic part 1243 coupled to the retainer 1231 can move in the first direction (X-axis direction).

[0310] More specifically, the 2-2 coupling region of the second elastic part 1243 and the mover 1230 can rotate in the first direction (X-axis direction) based on the second pattern region.

[0311] In other words, the mover 1230 can rotate or tilt based on a second pattern or a second pattern area used as a reference axis (or rotation axis).

[0312] For example, the mover 1230 is rotated by a first angle θ1 (X1->X1a or X1->X1b) in the X-axis direction by the first electromagnetic forces F1A and F1B between the third magnet 1251c disposed in the third mounting slot and the third coil 1252c disposed on the side of the third substrate. The first angle θ1 can be in the range of ±1° to ±3°. However, the present invention is not limited thereto.

[0313] refer to Figure 13 It can perform X-axis tilt. That is, rotation can be performed in the second direction (Y-axis direction) to implement OIS.

[0314] OIS can be implemented when the mover 1230 tilts or rotates in the Y-axis direction (or tilts in the X-axis direction).

[0315] In this embodiment, the first magnet 1251a and the second magnet 1251b disposed in the retainer 1231, together with the first coil 1252a and the second coil 1252b, can generate an electromagnetic force to tilt or rotate in the second direction (Y-axis direction). That is, through the aforementioned electromagnetic force, the retainer 1231 and the guide portion 1240 coupled to the retainer 1231 can rotate or move in the second direction (Y-axis direction).

[0316] Specifically, in the guide portion 1240, the 1-1 coupling region of the first elastic portion 1242, the support portion 1241, the second elastic portion 1243 and the mover 1231 can rotate or tilt in the second direction (X-axis tilt) based on the first pattern or the first pattern region of the first elastic portion 1242, which serves as a reference axis (or rotation axis).

[0317] For example, OIS can be achieved when the mover 1230 is rotated in the Y-axis direction (Y1->Y1a or Y1->Y1b) by a second angle θ2 through the second electromagnetic forces F2A and F2B between the first magnet 1251a and the second magnet 1251b disposed in the first mounting slot and the first coil 1252a and the second coil 1252b disposed on the sides of the second and second substrates. The second angle θ2 can be in the range of ±1° to ±3°. However, the present invention is not limited thereto.

[0318] As described above, when OIS is achieved by controlling the guide 1240 and the mover 1230 to rotate in a first direction (X-axis direction) or a second direction (Y-axis direction) using the electromagnetic force between the drive magnet in the retainer and the drive coil disposed in the housing, the second camera actuator according to the embodiment can minimize downsloping or tilting phenomena to provide optimal optical properties. Furthermore, as described above, the term "Y-axis tilt" corresponds to rotation or tilt in the first direction (X-axis direction), and the term "X-axis tilt" corresponds to rotation or tilt in the second direction (Y-axis direction).

[0319] Figure 14 This is a perspective view illustrating a second camera actuator according to another embodiment, and Figure 15 This is an exploded perspective view illustrating a second camera actuator according to another embodiment.

[0320] refer to Figure 14 and Figure 15 The second camera actuator 1200 according to an embodiment includes a protective cover 1210, a housing 1220, a mover 1230, a rotating plate 1240, and a drive unit 1250. Furthermore, it should be understood that the components are not assembled along lines illustrated in the exploded perspective view (e.g., double-dotted lines). In the second camera actuator 1200 according to another embodiment, the protective cover 1210, housing 1220, mover 1230, and drive unit 1250 described above correspond to the protective cover 1210, housing 1220, mover 1230, and drive unit 1250 described below, and the above can be applied. Furthermore, although the rotating plate 1240 described below differs from the guide unit 1240 that performs X-axis and Y-axis tilting, the rotating plate 1240 is capable of performing tilting actuation in the same manner. Furthermore, other components besides the rotating plate and the components coupled to the guide unit can be applied in the same way to this embodiment and the other embodiment.

[0321] First, the mover 1230 includes a retainer 1231, an optical component 1232 disposed on the retainer 1231, and a cover 1233 covering the rotating plate 1240 and coupled to the retainer 1231. The rotating plate 1240 can be positioned between the retainer 1231 and the cover 1233 and can be coupled to the mover 1230 and the housing 1220. Furthermore, the rotating plate 1240 can tilt relative to two axes. In an embodiment, the rotating plate 1240 can rotate in a first direction (X-axis direction) (corresponding to tilting along a second axis). Furthermore, the rotating plate 1240 can rotate in a second direction (Y-axis direction) (corresponding to tilting along the first axis). Additionally, 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. The components will be described below.

[0322] The protective cover 1210 can be positioned in a region (e.g., the outermost part) of the second camera actuator 1200 to surround the rotating plate 1240 and the drive section 1250, which will be described below.

[0323] The protective cover 1210 can block or reduce electromagnetic waves generated from the outside. Therefore, it is possible to reduce the occurrence of malfunctions in the rotating plate 1240 or the drive unit 1250.

[0324] The housing 1220 can be disposed within the protective cover 1210. Furthermore, the housing 1220 can be positioned inside the base plate portion 1255. The housing 1220 can be secured to the protective cover 1210 by being inserted into or aligned with it.

[0325] The housing 1220 may include a plurality of housing sides. In an embodiment, the housing 1220 may include a first housing side to a fifth housing side. Details thereto will be described below.

[0326] The housing 1220 may include a receiving portion 1226, which is a cavity between a plurality of housing sides.

[0327] The mover 1230 includes a retainer 1231 and an optical component 1232 disposed on the retainer 1231.

[0328] The retainer 1231 can be housed in the receiving portion 1226 of the housing 1220. The retainer 1231 may include a first retainer outer surface to a fourth retainer outer surface corresponding to the first housing side, the second housing side, the third housing side, and the fourth housing side, respectively. Details will be described below.

[0329] Optical component 1232 can be mounted on holder 1231. For this purpose, holder 1231 may include a mounting surface, and the mounting surface may be formed by a receiving portion. Optical component 1232 may include a reflective portion disposed therein. However, the invention is not limited thereto. Furthermore, optical component 1232 can reflect light reflected from the outside (e.g., an object) into the camera module. In other words, optical component 1232 can overcome the spatial limitations of the first and second camera actuators by changing the path of the reflected light. Therefore, it should be understood that the camera module can also provide a wide range of magnifications by increasing the optical path while minimizing thickness.

[0330] Optical component 1232 may be formed as a prism, mirror, etc., having at least one lens formed thereon.

[0331] The rotating plate 1240 can be disposed in the mover 1230. Furthermore, the rotating plate 1240 can be surrounded by and coupled to the mover 1230 by the plate cover 1233 and the retainer 1231. Additionally, the rotating plate 1240 can be coupled to the housing 1220 via a second protrusion.

[0332] The rotating plate 1240 may include a first protrusion projecting upward and downward (e.g., toward the third housing side and the protective cover) and a second protrusion projecting toward the housing (e.g., toward the first housing side and the second housing side). The mover 1230 may use the first and second protrusions to perform a first axis tilt and a second axis tilt. Details will be described below.

[0333] 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.

[0334] The driving magnet 1251 may include multiple magnets. In an embodiment, the driving magnet 1251 may include a first magnet 1251a, a second magnet 1251b, and a third magnet 1251c.

[0335] Each of the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c can be positioned in one of the outer surfaces of the retainer 1231. Furthermore, the first magnet 1251a and the second magnet 1251b can be positioned facing each other. Additionally, the third magnet 1251c can be positioned on the bottom surface of one of the outer surfaces of the retainer 1231. Details will be described below.

[0336] The drive coil 1252 may include multiple coils. In an embodiment, the drive coil 1252 may include a first coil 1252a, a second coil 1252b, and a third coil 1252c.

[0337] The first coil 1252a can be positioned opposite the first magnet 1251a. Therefore, as described above, the first coil 1252a can be positioned in the first housing hole 1221a of the first housing side portion 1221.

[0338] Furthermore, the second coil 1252b can be positioned opposite the second magnet 1251b. Therefore, as described above, the second coil 1252b can be positioned in the second housing hole 1222a of the second housing side portion 1222.

[0339] The first coil 1252a can be positioned facing the second coil 1252b. That is, the first coil 1252a and the second coil 1252b can be symmetrically positioned relative to a first direction. This can be similarly applied to the first magnet 1251a and the second magnet 1251b. Due to this configuration, precise X-axis tilting can be performed without tilting to one side through 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.

[0340] The third coil 1252c can be positioned opposite the third magnet 1251c. Therefore, as described above, the third coil 1252c can be positioned in the third housing hole 1223a of the third housing side 1223. The third coil 1252c and the third magnet 1251c generate electromagnetic force to perform Y-axis tilting of the mover 1230 and the guide 1240 based on the housing 1220.

[0341] In this case, the X-axis tilt is a tilt relative to the X-axis (or a tilt relative to the reference axis serving as the X-axis), and the Y-axis tilt is a tilt relative to the Y-axis (or a tilt relative to the reference axis serving as the Y-axis). Furthermore, the first direction in the figures is the X-axis direction and can be used interchangeably with the second axis direction, the second axis, etc. The second direction in the figures is the Y-axis direction and can be used interchangeably with the first axis direction, the first axis, etc. The second direction is a direction perpendicular to the first direction. Furthermore, the third direction in the figures is the Z-axis direction and can be used interchangeably with the third axis direction, etc. Furthermore, the third direction is a direction perpendicular to both the first and second directions. In addition, in this invention, the first direction (X-axis direction) corresponds to the direction of the optical axis of light incident on the second camera actuator, and the second direction (Y-axis direction) and the third direction (Z-axis direction) are directions perpendicular to the optical axis and can be tilted by the second camera actuator. The third direction can correspond to the direction from the rotating plate to the optical component or holder. Furthermore, the bottom surface refers to one side in the first direction, and within the housing, the third housing side can be the bottom surface, pointing inward toward the center of the camera actuator, and outward in the opposite direction. This invention should be understood based on the above. However, in the first camera actuator described below, it should be understood that the optical axis can also be changed to the Z-axis.

[0342] The Hall sensor unit 1253 may include multiple Hall sensors. In an embodiment, the Hall sensor unit 1253 may 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 may be positioned inside the first coil 1252a or the second coil 1252b. The first Hall sensor 1253a and the second Hall sensor 1253b can detect changes in magnetic flux inside the first coil 1252a or the second coil 1252b. Therefore, position sensing between the first magnet 1251a and the second magnet 1251b and the first Hall sensor 1253a and the second Hall sensor 1253b can be performed. A camera actuator according to an embodiment can use this to control X-axis tilt.

[0343] Furthermore, a third Hall sensor 1253c can be positioned inside the third coil 1252c. The third Hall sensor 1253c can detect changes in the magnetic flux inside the third coil 1252c. Therefore, position sensing between the third magnet 1251c and the third Hall sensor 1253c can be performed. A camera actuator according to an embodiment can use this to control Y-axis tilt.

[0344] The coupling portion 1254 may include a first coupling member 1254a, a second coupling member 1254b, and a third coupling member 1254c.

[0345] Each of the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be positioned in one of the placement grooves formed in the outer surface of the retainer 1231. Furthermore, the first coupling member 1254a and the second coupling member 1254b can be positioned facing each other. Additionally, the third coupling member 1254c can be positioned on the bottom surface (e.g., the outer surface of the third retainer) of the outer surface of the retainer 1231.

[0346] Furthermore, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can all be positioned between the first magnet 1251a to the third magnet 1251c and the retainer 1231.

[0347] The first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be yokes. Therefore, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be coupled to the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c, respectively.

[0348] Furthermore, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be respectively disposed in the first placement groove, the second placement groove, and the third placement groove of the retainer 1231, and can be easily coupled to the first placement groove, the second placement groove, and the third placement groove using an adhesive member injected through the groove formed in the first placement groove, the second placement groove, and the third placement groove.

[0349] Therefore, the first magnet 1251a, the second magnet 1251b and the third magnet 1251c can be easily coupled to the retainer 1231 via the first coupling member 1254a, the second coupling member 1254b and the third coupling member 1254c respectively.

[0350] Each of the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c can be positioned in one of the outer surfaces of the retainer 1231. Furthermore, the first magnet 1251a and the second magnet 1251b can be positioned facing each other. Additionally, the third magnet 1251c can be positioned on the bottom surface of one of the outer surfaces of the retainer 1231. Details will be described below.

[0351] The substrate portion 1255 can be positioned below the drive portion 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 coupled to the drive coil 1252 and the Hall sensor portion 1253 using surface mount technology (SMT). However, the present invention is not limited to this configuration.

[0352] The substrate portion 1255 can be positioned between the protective cover 1210 and the housing 1220 and coupled to the protective cover 1210 and the housing 1220. The coupling method can be performed differently as described above. Furthermore, through the above coupling, the drive coil 1252 and the Hall sensor portion 1253 can be positioned inside the outer surface of the housing 1220.

[0353] The substrate portion 1255 may include a circuit board having an electrically connectable wiring pattern such as a rigid printed circuit board (rigid PCB), a flexible PCB, a rigid-flexible PCB, etc. However, the present invention is not limited to such types.

[0354] Figure 16a This is a perspective view of a housing according to another embodiment. Figure 16b The diagram is in Figure 16a A side view of the shell observed in direction KD, and Figure 16c This is a side view of the fifth shell side shown in the figure. Figure 16d This is a side view of the first and second housing sides. Figure 16e The illustration shows a top view of the housing according to another embodiment, and Figure 16f This is a bottom view of the housing according to another embodiment. Figure 16g This is a perspective view of the side of the fourth housing shown in the diagram, and Figure 16h This is a view of the inner surface of the fourth housing side.

[0355] refer to Figures 16a to 16h 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.

[0356] The first housing side portion 1221 and the second housing side portion 1222 can be arranged facing each other. Furthermore, the third housing side portion 1223 can be disposed on the bottom surface of the housing 1220. The fourth housing side portion 1224 and the fifth housing side portion 1225 can be arranged facing each other and disposed between the first housing side portion 1221 and the second housing side portion 1222.

[0357] The third housing side 1223 can contact the first housing side 1221, the second housing side 1222, the fourth housing side 1224, and the fifth housing side 1225.

[0358] The first housing side portion 1221 may include a first housing hole 1221a. The first coil, which will be described below, may be positioned in the first housing hole 1221a.

[0359] The first housing side portion 1221 may include a first coupling protrusion (not shown). The first housing side portion 1221 may be easily coupled to the substrate portion using the first coupling protrusion (not shown).

[0360] Furthermore, the first housing side portion 1221 may include a first mounting protrusion 1221c. This first mounting protrusion 1221c can be positioned in the upper or lower portion of the first housing side portion 1221. The first mounting protrusion 1221c can easily support the substrate portion. Therefore, the coupling force between the first housing side portion and the substrate portion can be increased.

[0361] Furthermore, the first housing side portion 1221 and the second housing side portion 1222 may include a second protruding receiving groove G2 formed inward from the side surface or protruding in the third direction. The second protruding receiving groove G2 includes a 2-1 protruding receiving groove G2a and a 2-2 protruding receiving groove G2b, and the invention will be described below based on them. First, the first housing side portion 1221 may include a 2-1 protruding receiving groove G2a formed inward from the side surface.

[0362] A 2-1 protrusion receiving groove G2a may be provided in the surface where the first housing side 1221 contacts the fourth housing side 1224. This 2-1 protrusion receiving groove G2a may be positioned to correspond to the 1-1 protrusion receiving groove G1a of the fourth housing side 1224, which will be described below.

[0363] The second protrusion, which will be described below, can be positioned between the 2-1 protrusion receiving groove G2a and the 1-1 protrusion receiving groove G1a. Therefore, the rotating plate, the housing 1220, and the mover 1230 can be coupled to each other.

[0364] Furthermore, the second housing side portion 1222 may include a second housing hole 1222a. Additionally, the second coil, which will be described below, may be positioned within the second housing hole 1222a.

[0365] The first housing hole 1221a and the second housing hole 1222a can be positioned facing each other. For example, the first housing hole 1221a and the second housing hole 1222a can be symmetrically arranged with respect to a first direction (X-axis direction) or a third direction (Z-axis direction). Furthermore, the first coil and the second coil can be electrically connected and coupled to a substrate component disposed outside the component 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 portion, and current can flow through it. This current is a component of electromagnetic force, through which the second camera actuator can perform tilting relative to the X-axis.

[0366] The second housing side portion 1222 may include a second coupling protrusion (not shown). The second housing side portion 1222 may be easily coupled to the substrate portion using the second coupling protrusion (not shown).

[0367] Furthermore, the second housing side portion 1222 may include a second mounting protrusion 1222c. The second mounting protrusion 1222c may be positioned in the upper or lower portion of the second housing side portion 1222. The second mounting protrusion 1222c can easily support the substrate portion. Therefore, the coupling force between the second housing side portion and the substrate portion can be increased.

[0368] Furthermore, the second housing side portion 1222 may include a 2-2 protrusion receiving groove formed inward from the side surface. The 2-2 protrusion receiving groove G2b may be disposed in the surface of the second housing side portion 1222 that contacts the fourth housing side portion 1224. The 2-2 protrusion receiving groove G2b may be positioned to correspond to the 1-2 protrusion receiving groove G1b of the fourth housing side portion 1224.

[0369] The second protrusion, which will be described below, can be positioned between the 2-2 protrusion receiving groove G2b and the 1-2 protrusion receiving groove G1b. Therefore, the rotating plate, the housing 1220, and the mover 1230 can be coupled to each other.

[0370] Furthermore, the third housing side portion 1223 may include a third housing hole 1223a. A third coil, which will be described below, may be positioned in the third housing hole 1223a. The third coil may be coupled to the substrate portion. In an embodiment, the third coil may be electrically connected to the substrate portion 1255, and current may flow through it. This current is a component of an electromagnetic force, by which the second camera actuator can perform tilting relative to the Y-axis.

[0371] The third housing side portion 1223 may include a third coupling protrusion (not shown). The third housing side portion 1223 may be easily coupled to the substrate portion using the third coupling protrusion (not shown).

[0372] The fourth housing side 1224 can contact the first housing side 1221, the second housing side 1222, and the third housing side 1223. Specifically, the fourth housing side 1224 can be disposed on the third housing side 1223. The lower surface of the fourth housing side 1224 can contact the upper surface of the third housing side 1223, and the fourth housing side 1224 can be supported by the third housing side 1223. The fourth housing side 1224 may not be positioned in the optical path.

[0373] The fourth housing side portion 1224 may include a first housing base 1224a, a first housing extension 1224b, and a second housing extension 1224c.

[0374] The first housing extension 1224b and the second housing extension 1224c may extend from the first housing base 1224a in a third direction (Z-axis direction). In particular, the first housing extension 1224b and the second housing extension 1224c extend from the first housing base 1224a toward the fifth housing side 1225.

[0375] The first housing base 1224a can be positioned opposite the fifth housing side 1225. Furthermore, the first housing base 1224a can be set apart from the cover by a predetermined distance, as will be described below, and can face the cover.

[0376] The first housing extension 1224b and the second housing extension 1224c can be positioned at the end of the first housing base 1224a in the second direction (Y-axis direction) and can extend in the third direction (Z-axis direction).

[0377] The first housing extension 1224b and the second housing extension 1224c can contact the first housing side 1221 and the second housing side 1222, respectively.

[0378] Furthermore, the fourth housing side portion 1224 may include a first protrusion receiving groove G1 in its inner surface. The first protrusion receiving groove G1 may include a 1-1 protrusion receiving groove G1a and a 1-2 protrusion receiving groove G1b.

[0379] 1-1 The protrusion receiving groove G1a can be positioned in the surfaces where the first housing extension 1224b and the first housing side 1221 contact each other. Furthermore, 1-2 the protrusion receiving groove G1b can be positioned in the surfaces where the second housing extension 1224c and the second housing side 1222 contact each other.

[0380] The second protrusion, as described below, can be positioned within the 1-1 protrusion receiving groove G1a and the 1-2 protrusion receiving groove G1b. Furthermore, the 1-1 protrusion receiving groove G1a and the 1-2 protrusion receiving groove G1b can be arranged side-by-side in the second direction (Y-axis direction). That is, the 1-1 protrusion receiving groove G1a and the 1-2 protrusion receiving groove G1b can overlap in the second direction (Y-axis direction). Therefore, the second protrusion positioned within the 1-1 protrusion receiving groove G1a and the 1-2 protrusion receiving groove G1b can rotate based on the second direction (Y-axis direction). In other words, tilting along one axis can be performed by the second protrusion.

[0381] As described above, the 1-1 protrusion receiving groove G1a can be positioned to correspond to the 2-1 protrusion receiving groove G2a. Furthermore, as described above, the 1-2 protrusion receiving groove G1b can be positioned to correspond to the 2-2 protrusion receiving groove G2b.

[0382] The fifth housing side 1225 may be configured to face the fourth housing side 1224. The fifth housing side 1225 may include an opening 1225a. Therefore, light passing through or reflected by the optical component can move through the opening 1225a.

[0383] Furthermore, the fifth housing side portion 1225 may include a housing protrusion 1225b. This housing protrusion 1225b may protrude outwards. The housing 1220 can be coupled to a first camera actuator disposed externally using the housing protrusion 1225b. Therefore, the reliability of the camera module can be improved.

[0384] Furthermore, the fifth housing side portion 1225 may include a protrusion 1225b and a patterned portion (not shown) having a pattern surrounding the housing protrusion 1225b. This patterned portion (not shown) may be positioned further inwardly stepped than the housing protrusion 1225b. That is, the patterned portion (not shown) may be positioned further inward than the housing protrusion 1225b.

[0385] An adhesive member can be applied to the patterned portion (not shown). Therefore, the contact area between the adhesive member and the fifth housing side portion 1225 can be increased on the patterned portion (not shown). Consequently, the coupling force between the second actuator (or housing 1220) and the first actuator can be increased.

[0386] Furthermore, the housing 1220 may include a receiving portion 1226 formed internally by the first housing side 1221 to the fifth housing side 1225. The mover 1230 and the rotating plate 1240 may be positioned in the receiving portion 1226.

[0387] Figure 17a The illustration is a perspective view of a mobile device according to another embodiment, and Figure 17bThis is a perspective view illustrating a retainer according to another embodiment. Figure 17c and Figure 17d The illustration is a side view of the mobile device according to an embodiment, and Figure 17e This is a bottom view of a mover according to another embodiment.

[0388] refer to Figures 17a to 17e The mover 1230 according to the embodiment may include a retainer 1231, an optical component 1232 disposed on the retainer 1231, and a cover 1233 covering the rotating plate 1240 and coupled to the retainer 1231.

[0389] First, the optical component 1232 can be mounted on the holder 1231. The optical component 1232 can be a prism, a mirror, etc., as described above, but is not limited to these.

[0390] Furthermore, the retainer 1231 may include a mounting surface 1231k on which the optical member 1232 is mounted. The mounting surface 1231k may be an inclined surface. Additionally, the retainer 1231 may include a jaw portion SP at its lower portion. The jaw portion SP in the retainer 1231 can prevent movement of the optical member 1232. Therefore, light incident from the upper portion can pass through the optical member 1232 and the opening on the side of the fifth housing and move in the third direction (Z-axis direction).

[0391] In addition, the retainer 1231 may include a plurality of outer surfaces. For example, the retainer 1231 may include a first retainer outer surface 1231S1, a second retainer outer surface 1231S2, a third retainer outer surface 1231S3, and a fourth retainer outer surface 1231S4.

[0392] The outer surface 1231S1 of the first retainer can be positioned to face the outer surface 1231S2 of the second retainer. That is, the outer surface 1231S1 of the first retainer and the outer surface 1231S2 of the second retainer can be symmetrically arranged with respect to the first direction (X-axis direction).

[0393] The outer surface 1231S1 of the first retainer can be positioned to face the side 1221 of the first housing. Furthermore, the outer surface 1231S2 of the second retainer can be positioned to face the side 1222 of the second housing.

[0394] Furthermore, the outer surface 1231S1 of the first retainer may include a first mounting groove 1231S1a. Furthermore, the outer surface 1231S2 of the second retainer may include a second mounting groove 1231S2a. The first mounting groove 1231S1a and the second mounting groove 1231S2a may be symmetrically arranged relative to a first direction (X-axis direction).

[0395] Furthermore, the first coupling member and the first magnet, as described below, can be disposed in the first mounting groove 1231S1a, and the second coupling member and the second magnet 1251b can be disposed in the second mounting groove 1231S2a. The first magnet and the second magnet can also be symmetrically arranged relative to the first direction (X-axis direction). Furthermore, the first coupling member and the second coupling member can also be symmetrically arranged relative to the first direction (X-axis direction).

[0396] Furthermore, the first magnet and the second magnet can overlap in the second direction, and the first coupling member and the second coupling member can also overlap in the second direction. As described above, due to the positions of the first and second mounting slots and the first and second magnets, the electromagnetic force induced by the magnets can be coaxially provided to the outer surfaces 1231S1 and 1231S2 of the first holder. For example, the region of the outer surface S1231S1 of the first holder on which the electromagnetic force is applied (e.g., the part where the electromagnetic force is strongest) and the region of the outer surface S1231S1 of the second holder on which the electromagnetic force is applied (e.g., the part where the electromagnetic force is strongest) can be positioned on an axis parallel to the second direction (Y-axis direction). Therefore, X-axis tilting can be precisely performed.

[0397] Furthermore, the outer surfaces 1231S1 and 1231S2 of the first and second retainers may additionally include grooves (not shown). Due to these grooves (not shown), the weight of the retainer 1231 is reduced, and therefore, energy consumption can be minimized when performing one-axis or two-axis tilting. That is, the amount of current applied to the first, second, and third coils can be minimized, and correspondingly, energy efficiency can be improved. Furthermore, the aforementioned grooves (not shown) can be symmetrically arranged relative to the first direction (X-axis direction). Therefore, the center of gravity of the retainer 1231 is prevented from shifting to one side, and tilting can thus be performed with a uniform force.

[0398] The third retainer outer surface 1231S3 may be an outer surface that contacts the first retainer outer surface 1231S1 and the second retainer outer surface 1231S2, and extends in a second direction (Y-axis direction) between the first retainer outer surface 1231S1 and the second retainer outer surface 1231S2. Therefore, the third retainer outer surface 1231S3 may be positioned between the first retainer outer surface 1231S1 and the second retainer outer surface 1231S2.

[0399] Furthermore, the outer surface 1231S3 of the third retainer can be the bottom surface of the retainer 1231. The outer surface 1231S3 of the third retainer can be positioned to face the side portion 1223 of the third housing. Furthermore, the outer surface 1231S3 of the third retainer can contact the side portion 1223 of the third housing.

[0400] Furthermore, the outer surface 1231S3 of the third holder may include a third mounting groove 1231S3a. A third magnet 1251c may be disposed in the third mounting groove 1231S3a. Additionally, at least a portion of the third housing hole 1223a may overlap the third mounting groove 1231S3a in a first direction (X-axis direction). Therefore, the third magnet 1251c in the third mounting groove 1231S3a and the third coil 1252c in the third housing hole 1223a may be positioned facing each other. Furthermore, the third magnet 1251c and the third coil 1252c generate electromagnetic force, and thus the camera actuator can perform Y-axis tilting.

[0401] Furthermore, although X-axis tilting is performed by multiple magnets (first magnet 1251a and second magnet 1251b), Y-axis tilting can be performed by only the third magnet 1251c.

[0402] In an embodiment, the area of ​​the third mounting slot 1231S3a may differ from the area of ​​the first mounting slot 1231S1a or the second mounting slot 1231S2a. For example, the area of ​​the third mounting slot 1231S3a may be larger than the area of ​​the first mounting slot 1231S1a or the second mounting slot 1231S2a. Due to this configuration, Y-axis tilting can be performed by current control similar to that used to perform X-axis tilting.

[0403] The outer surface 1231S3 of the third retainer may additionally include a groove 1231S3b. Due to the groove 1231S3b, the weight of the retainer 1231 is reduced, and therefore, energy consumption can be minimized when performing one-axis tilting or two-axis tilting. That is, the amount of current applied to the first coil, the second coil, and the third coil can be minimized, and correspondingly, energy efficiency can be improved.

[0404] Furthermore, additional grooves 1231S3b can be provided as a plurality of grooves 1231S3b in the outer surface 1231S3 of the third retainer, and when a plurality of grooves 1231S3b are present, the plurality of grooves 1231S3b can be symmetrically arranged relative to the first direction (X-axis direction).

[0405] The fourth retainer outer surface 1231S4 may be an outer surface that contacts the first retainer outer surface 1231S1 and the second retainer outer surface 1231S2, and extends from the third retainer outer surface 1231S3 in a first direction (X-axis direction). Furthermore, the fourth retainer outer surface 1231S4 may be positioned between the first retainer outer surface 1231S1 and the second retainer outer surface 1231S2.

[0406] The outer surface 1231S4 of the fourth retainer may include a receiving groove PG.

[0407] The rotating plate can be placed in the receiving groove PG. That is, the receiving groove PG can accommodate the rotating plate.

[0408] In an embodiment, the receiving groove PG may include a first receiving groove PG1 and a second receiving groove PG2. The first receiving groove PG1 may receive the base of the rotating plate, a first base protrusion, and a second base protrusion. Furthermore, the second receiving groove PG2 may receive a first extended protrusion.

[0409] The length of each of the second receiving grooves PG2 can differ from the length of the first receiving groove PG1 in a third direction. Therefore, the rotating plate in the first receiving groove PG1 can be maintained in the mover 1230. Furthermore, both the accuracy and reliability of the camera actuator according to the embodiment can be improved.

[0410] The first receiving groove PG1 may include a first receiving area PG1a, a second receiving area PG1b, and a third receiving area PG1c in which the base is disposed.

[0411] In one embodiment, the first protrusion may be disposed in the first receiving region PG1a and the second receiving region PG1b. Furthermore, the base of the rotating plate may be disposed in the third receiving region PG1c.

[0412] The first receiving area PG1a and the second receiving area PG1b can be positioned above and below the third receiving area PG1c, respectively. Furthermore, the first receiving area PG1a and the second receiving area PG1b can be positioned along the bisectors of the third receiving area PG1c in the second direction (Y-axis direction). In other words, the first receiving area PG1a and the second receiving area PG1b can be positioned at the central portion of the third receiving area PG1c.

[0413] The second receiving groove PG2 can be positioned adjacent to the first receiving groove PG1, and, as described above, is provided as a plurality of second receiving grooves PG2. The second receiving groove PG2 can be positioned above the first receiving region PG1a and below the second receiving region PG1b. In an embodiment, the second receiving groove PG2 may include 2-1 receiving groove PG2a and 2-2 receiving groove PG2b.

[0414] 2-1 The receiving groove PG2a can be positioned above the first receiving area PG1a. Furthermore, 2-2 the receiving groove PG2b can be positioned below the second receiving area PG1b.

[0415] Receiving grooves PG2a (2-1) and PG2b (2-2) can be positioned to overlap in a first direction (X-axis direction). Furthermore, receiving grooves PG2a (2-1) and PG2b (2-2) can be positioned on the bisector of a third receiving region PG1c in a second direction (Y-axis direction). In other words, receiving grooves PG2a (2-1) and PG2b (2-2) can be positioned corresponding to the central portion of the third receiving region PG1c. Due to this configuration, when tilting (e.g., bi-axial tilting) is performed by the first protrusion, the force applied between the rotating plate and the mover 1230 may not be concentrated on one side. In other words, the tilting of the mover 1230 is not biased to one side, and thus the tilting accuracy can be improved. Furthermore, force imbalance can be resolved to improve the reliability of the assembly.

[0416] Furthermore, the outer surface 1231S4 of the fourth retainer may include a coupling groove 1231S4h. A coupling protrusion 1233p may be disposed in the coupling groove 1231S4h. Accordingly, the retainer 1231 and the cover 1233 may be coupled. In addition, the retainer 1231 and the cover 1233 may surround the rotating plate.

[0417] The coupling groove 1231S4h can be configured to be separate from the receiving groove PG. Furthermore, the coupling groove 1231S4h can be positioned at the edge of the outer surface 1231S4 of the fourth retainer. Therefore, even when biaxial tilting is performed by the first and second protrusions positioned at the edge of the outer surface 1231S4 of the fourth retainer, the coupling force between the retainer 1231 and the cover 1233 can be easily maintained.

[0418] In one embodiment, the third receiving region PG1c can be positioned in the central portion of the outer surface 1231S4 of the fourth retainer. Furthermore, the first receiving region PG1a can be positioned above the third receiving region PG1c. Additionally, the second receiving region PG1b can be positioned below the third receiving region PG1c.

[0419] Furthermore, the 2-1 receiving groove PG2a can be positioned above the first receiving area PG1a. In other words, the first receiving area PG1a can be positioned between the 2-1 receiving groove PG2a and the third receiving area PG1c.

[0420] Furthermore, the 2-2 receiving groove PG2b can be positioned below the second receiving area PG1b. In other words, the second receiving area PG1b can be positioned between the 2-2 receiving groove PG2b and the third receiving area PG1c.

[0421] In an embodiment, the length W1 of the third receiving region PG1c in the second direction can be greater than the length W2 of the first receiving region PG1a or the second receiving region PG1b, or the length W3 of the second receiving groove PG2 in the second direction. Due to this configuration, when the retainer 1231 and the cover 1233 are tilted, the rotational force can be effectively transmitted to the rotating plate through the base of the rotating plate. Therefore, resistance is minimized, and thus the efficiency of the drive unit can be improved.

[0422] Furthermore, the length W2 of the first receiving area PG1a or the second receiving area PG1b in the second direction can be greater than the length W3 of the second receiving groove PG2 in the second direction. Therefore, it is easy to prevent the rotating plate in the receiving groove PG from separating from the retainer 1231 and the cover 1233.

[0423] Figure 17f The illustration is a perspective view of a cover plate according to another embodiment, and Figure 17g This is a side view of a cover according to another embodiment. Figure 17h The illustration shows a top view of a cover according to another embodiment, and Figure 17i This is a side view of the cover according to another embodiment.

[0424] refer to Figures 17f to 17i As described above, the cover 1233 can be coupled to the retainer 1231.

[0425] The cover 1233 may include a plate groove 1233g. In addition, the cover 1233 may surround the rotating plate through the plate groove 1233g.

[0426] In an embodiment, the plate groove 1233g may include a first plate groove 1233g1 and a second plate groove 1233g2. The first plate groove 1233g1 may accommodate the base of the rotating plate, a first base protrusion, and a second base protrusion. In addition, the second plate groove 1233g2 may accommodate a first extended protrusion.

[0427] The length of each of the second plate slots 1233g2 can differ from the length of the first plate slot 1233g1 in a third direction. Therefore, the rotating plate in the first plate slot 1233g1 can be maintained in the mover 1230. Furthermore, both the accuracy and reliability of the camera actuator according to the embodiment can be improved.

[0428] The first plate groove 1233g1 may include a first plate region 1233g1a, a second plate region 1233g1b, and a third plate region 1233g1c.

[0429] The first protrusion can be placed in the first plate region 1233g1a and the second plate region 1233g1b. Furthermore, the base of the rotating plate can be placed in the third plate region 1233g1c.

[0430] The first plate region 1233g1a and the second plate region 1233g1b can be positioned above and below the third plate region 1233g1c. Furthermore, the first plate region 1233g1a and the second plate region 1233g1b can be positioned along the bisectors 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 positioned at the central portion of the third plate region 1233g1c.

[0431] The second plate groove 1233g2 can be positioned adjacent to the first plate groove 1233g1, and as described above, can be provided as a plurality of second plate grooves 1233g2. The second plate grooves 1233g2 can be positioned above the first plate region 1233g1a and below the second plate region 1233g1b. In an embodiment, the second plate groove 1233g2 may include 2-1 plate grooves 1233g2a and 2-2 plate grooves 1233g2b.

[0432] 2-1 Plate groove 1233g2a can be positioned above the first plate area 1233g1a. Furthermore, 2-2 Plate groove 1233g2b can be positioned below the second plate area 1233g1b.

[0433] Plate grooves 2-1 (1233g2a) and 2-2 (1233g2b) can be positioned to overlap in a first direction (X-axis direction). Furthermore, plate grooves 2-1 (1233g2a) and 2-2 (1233g2b) can be positioned on the bisectors of the third plate region 1233g1c in a second direction (Y-axis direction). In other words, plate grooves 2-1 (1233g2a) and 2-2 (1233g2b) can be positioned corresponding to the central portion of the third plate region 1233g1c. Due to this configuration, when tilting (e.g., bi-axial tilting) is performed by the first protrusion, the force applied to the rotating plate and the mover 1230 may not be concentrated on one side. In other words, the tilting of the mover 1230 is not biased to one side, and thus the tilting accuracy can be improved. Furthermore, force imbalance can be resolved to improve the reliability of the assembly.

[0434] Furthermore, the cover 1233 may include a coupling protrusion 1233p positioned on its inner surface. The coupling protrusion 1233p may be inserted into the coupling groove 1231S4h. Thus, the retainer 1231 and the cover 1233 may be coupled. Additionally, the retainer 1231 and the cover 1233 may surround the rotating plate.

[0435] The coupling protrusion 1233p can be configured to be separate from the plate groove 1233g. Furthermore, the coupling recess 1231S4h can be positioned at the edge of the cover 1233. Therefore, even when biaxial tilting is performed by the first and second protrusions positioned at the edge of the cover 1233, the coupling force between the retainer 1231 and the cover 1233 can be easily maintained.

[0436] In this embodiment, the third plate region 1233g1c can be positioned in the central portion of the cover 1233. Furthermore, the first plate region 1233g1a can be positioned above the third plate region 1233g1c. Additionally, the second plate region 1233g1b can be positioned below the third plate region 1233g1c.

[0437] Furthermore, the 2-1 plate groove 1233g2a can be positioned above the first plate region 1233g1a. In other words, the first plate region 1233g1a can be positioned between the 2-1 plate groove 1233g2a and the third plate region 1233g1c.

[0438] Furthermore, the 2-2 plate groove 1233g2b can be positioned below the second plate region 1233g1b. In other words, the second plate region 1233g1b can be positioned between the 2-2 plate groove 1233g2b and the third plate region 1233g1c.

[0439] The first plate groove 1233g1 can correspond to the first receiving groove PG1, and the second plate groove 1233g2 can correspond to the second receiving groove PG2. Therefore, in the embodiment, the length of the third plate region 1233g1c in the second direction can be greater than the lengths of the first plate region 1233g1a, the second plate region 1233g1b, or the second plate groove 1233g2 in the second direction. Due to this configuration, when the retainer 1231 and the plate cover 1233 are tilted, the rotational force can be effectively transmitted to the rotating plate through the base of the rotating plate. Therefore, resistance is minimized, and thus the efficiency of the drive unit can be improved.

[0440] Furthermore, the length of the first plate region 1233g1a or the second plate region 1233g1b in the second direction can be greater than the length of the second plate groove 1233g2 in the second direction. Therefore, it is easy to prevent the rotating plate in the plate groove 1233g from separating from the retainer 1231 and the plate cover 1233.

[0441] Figure 18a The illustration is a perspective view of a rotating plate according to another embodiment, and Figure 18b This is a perspective view of a rotating plate according to another embodiment. Figure 18c The diagram is along Figure 18a A cross-sectional view of the rotating plate of line AA' in the diagram, and Figure 18d This is a top view of a rotating plate according to another embodiment.

[0442] The rotating plate 1240 according to an embodiment may include a base BS, a first protrusion PR1 disposed on an upper surface and a lower surface of the base BS facing each other in a first direction (X-axis direction), and a second protrusion PR2 disposed on a side surface of the base BS facing each other in a second direction (Y-axis direction). Depending on the structure, the surfaces on which the first and second protrusions are formed may be opposite each other; however, in this specification, the invention will be described based on the above.

[0443] In an embodiment, the base BS may have a quadrilateral shape on a plane. In the base BS, the length in the second direction (Y-axis direction) may be greater than the length in the first direction (X-axis direction). However, the base BS is not limited to this and can be formed in one of various shapes.

[0444] As described above, the first protrusion PR1 can be symmetrically positioned on the upper and lower surfaces of the base BS in the first direction (X-axis direction). For example, the first protrusion PR1 may include a 1-1 protrusion on the upper surface of the base BS and a 1-2 protrusion on the lower surface of the base BS. However, in the following description, the invention will be based on the first protrusion.

[0445] One of the first protrusions PR1 may include a first base protrusion PRB1 disposed above (or below) the base BS.

[0446] Furthermore, the first protrusion PR1 may include a first extended protrusion PRP1 disposed between the first base protrusion PRB1 and the base BS. The first extended protrusion PRP1 may be disposed on the first base protrusion PRB1.

[0447] Each of the first base protrusion PRB1 and the first extended protrusion PRP1 can have a circular shape in the YZ plane. Therefore, the rotating plate 1240 can easily perform tilting (second axis tilting) relative to the first direction (X-axis direction).

[0448] The first protrusion PR1 can be positioned on the bisector VL1 of the base BS in the third direction (Z-axis direction). Furthermore, the starting points C1 and C2 of the first protrusion PR1 can be positioned on the bisector VL1 of the base BS in the third direction (Z-axis direction). Therefore, when tilting is performed, the force applied to the base BS is uniform, and thus the reliability of the component can be improved.

[0449] As described above, the second protrusion PR2 can be positioned symmetrically on two side surfaces of the base BS in the second direction (Y-axis direction). For example, the second protrusion PR2 may include a 2-1 protrusion on one side surface of the base BS and a 2-2 protrusion on the other side surface of the base BS. However, the invention will be described below based on the second protrusion.

[0450] The second protrusion PR2 may include a second base protrusion PRB2 disposed on the side surface of the base BS.

[0451] Furthermore, the second protrusion PR2 may include a second extended protrusion PRP2 disposed between the second base protrusion PRB2 and the base BS. The second extended protrusion PRP2 may be disposed on the second base protrusion PRRB2.

[0452] Each of the second base protrusion PRB2 and the second extension protrusion PRP2 can have a circular shape in the XZ plane. Therefore, the rotating plate 1240 can easily perform tilting (first axis tilting) relative to the second direction (Y-axis direction).

[0453] The second protrusion PR2 can be positioned on the bisector of the base BS in the first direction (X-axis direction). Furthermore, the starting point of the second protrusion PR2 can be positioned on the bisector of the base BS in the third direction (Z-axis direction). Therefore, when tilting is performed, the force applied to the base BS is uniform, and thus the reliability of the component can be improved.

[0454] Furthermore, as described above, the first protrusion PR1 can be provided as a plurality of first protrusions PR1 that may overlap in the first direction (X-axis direction). Furthermore, as described above, the second protrusion PR2 can be provided as a plurality of second protrusions PR2 that may overlap in the second direction (Y-axis direction). Therefore, the camera actuator according to the embodiment can perform precise tilting.

[0455] Furthermore, the length W4 of the base BS in the second direction (Y-axis direction) can be greater than the length r1 of the first base protrusion PRB1 and the length r2 of the first extension protrusion PRP1 in the second direction (Y-axis direction). As described above, since each of the first base protrusion PRB1 and the first extension protrusion PRP1 has a circular shape in the plane, the lengths r1 and r2 in the second direction (Y-axis direction) can be diameters, and the invention will be described based on this. Due to this configuration, rotational force can be effectively transmitted to the rotating plate through the base of the rotating plate. Therefore, resistance is minimized, and thus the efficiency of the drive unit can be improved.

[0456] Furthermore, the first protrusion PR1 can contact the lubrication member applied in the second receiving groove PG2 and the second plate groove 1223G2. The second protrusion PR2 can contact the lubrication member applied in the first protrusion receiving groove G1 and the second protrusion receiving groove G2.

[0457] Furthermore, according to the embodiment, the diameter r1 of the first base protrusion PRB1 can be larger than the diameter r2 of the first extended protrusion PRP1. Therefore, the rotating plate 1240 can be separated from the retainer and the cover in the first direction (X-axis direction) without being separated by the first base protrusion PRB1.

[0458] Furthermore, the length h1 of the base BS in the first direction (X-axis direction) can be greater than the length h2 of the second base protrusion PRB2 and the length h3 of the second extension protrusion PRP2 in the first direction (X-axis direction). As described above, since each of the second base protrusion PRB2 and the second extension protrusion PRP2 has a circular shape in the plane, the lengths h2 and h3 in the first direction (X-axis direction) can be diameters, and the present invention will be described based on this. Furthermore, with the above configuration, rotational force can be effectively transmitted to the rotating plate through the base of the rotating plate. Therefore, resistance is minimized, and thus the efficiency of the drive unit can be improved.

[0459] Furthermore, according to the embodiment, the diameter h2 of the second base protrusion PRB2 can be larger than the diameter h3 of the second extension protrusion PRP2. Therefore, the rotating plate 1240 can be separated from the retainer and the plate cover in the second direction (Y-axis direction) without being separated by the second base protrusion PRB2.

[0460] Figure 19 This is a view of the drive unit according to another embodiment.

[0461] refer to Figure 19 As described 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.

[0462] Furthermore, as described above, the driving magnet 1251 may include a first magnet 1251a, a second magnet 1251b, and a third magnet 1251c that provide driving force via electromagnetic force. Each of the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c may be positioned in one of the outer surfaces of the retainer 1231.

[0463] Furthermore, the drive coil 1252 may include multiple coils. In an embodiment, the drive coil 1252 may include a first coil 1252a, a second coil 1252b, and a third coil 1252c.

[0464] The first coil 1252a can be positioned opposite the first magnet 1251a. Therefore, as described above, the first coil 1252a can be positioned in the first housing hole 1221a of the first housing side 1221. Furthermore, the second coil 1252b can be positioned opposite the second magnet 1251b. Therefore, as described above, the second coil 1252b can be positioned in the second housing hole 1222a of the second housing side 1222.

[0465] When OIS is implemented by controlling the mover 1230 to rotate in a first direction (X-axis direction) or a second direction (Y-axis direction) using the electromagnetic force between the drive magnet 1251 and the drive coil 1252, the second camera actuator according to the embodiment is able to minimize the occurrence of downsloping or tilting phenomena to provide optimal optical properties.

[0466] Furthermore, according to the embodiment, since OIS is achieved using a rotating plate 1240 of a guide portion disposed between the housing 1220 and the mover 1230, the size limitation of the actuator is solved, and thus it is possible to provide an ultra-thin and ultra-small camera actuator and a camera module including the camera actuator.

[0467] The coupling portion 1254 may include a first coupling member 1254a, a second coupling member 1254b, and a third coupling member 1254c.

[0468] Furthermore, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can all be positioned between the first magnet 1251a to the third magnet 1251c and the retainer 1231.

[0469] The first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be yokes. Therefore, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be coupled to the first magnet 1251a, the second magnet 1251b, and the third magnet 1251c, respectively.

[0470] Furthermore, the first coupling member 1254a, the second coupling member 1254b, and the third coupling member 1254c can be respectively disposed in the first placement groove, the second placement groove, and the third placement groove, and can be easily coupled to the first placement groove, the second placement groove, and the third placement groove by an adhesive member injected through the groove formed in the first placement groove, the second placement groove, and the third placement groove.

[0471] 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.

[0472] The first substrate side portion 1255a and the second substrate side portion 1255b can be configured to face each other. Furthermore, the third substrate side portion 1255c can be positioned between the first substrate side portion 1255a and the second substrate side portion 1255b.

[0473] Furthermore, the first substrate side portion 1255a can be positioned between the first housing side portion and the protective cover, and the second substrate side portion 1255b can be positioned between the second housing side portion and the protective cover. Additionally, the third substrate side portion 1255c can be positioned between the third housing side portion and the protective cover and can be the bottom surface of the substrate portion 1255.

[0474] The first substrate side portion 1255a can be coupled to and electrically connected to the first coil 1252a. Furthermore, the first substrate side portion 1255a can be coupled to and electrically connected to the first Hall sensor 1253a.

[0475] The second substrate side portion 1255b can be coupled and electrically connected to the second coil 1252b. Furthermore, it should be understood that the second substrate side portion 1255b can also be coupled and electrically connected to the second Hall sensor 1253b.

[0476] Furthermore, the first substrate side portion 1255a and the second substrate side portion 1255b can extend in the third direction (Z-axis direction). Therefore, the first substrate side portion 1255a and the second substrate side portion 1255b can have a region extending from the fifth housing side portion in the third direction (Z-axis direction).

[0477] Furthermore, the third substrate side portion 1255c can be coupled and electrically connected to the third coil 1252c. Additionally, the third substrate side portion 1255c can be coupled and electrically connected to the third Hall sensor 1253c.

[0478] Figure 20 This is a perspective view illustrating the state in which the protective cover and substrate are removed from the second camera actuator according to an embodiment. Figure 21a It is along Figure 20 A cross-sectional view of line BB' in the diagram. Figure 21b It is along Figure 20 The cross-sectional view of line CC' in the diagram, and Figure 21c It is along Figure 20 The cross-sectional view of line DD' in the diagram.

[0479] refer to Figure 20 and Figures 21a to 21c The first coil 1252a can be positioned on the first housing side 1221, and the first magnet 1251a and the first coupling member 1254a can be positioned on the first retainer outer surface 1231S1 of the retainer 1231.

[0480] Furthermore, the first coil 1252a and the first magnet 1251a can be positioned relative to each other. At least a portion of the first magnet 1251a can overlap the first coil 1252a in the second direction (Y-axis direction). Additionally, at least a portion of the first coupling member 1254a can overlap the first coil 1252a in the second direction (Y-axis direction).

[0481] Furthermore, the second coil 1252b can be positioned on the second housing side 1222, and the second magnet 1251b and the second coupling member 1254b can be positioned on the second retainer outer surface 1231S2 of the retainer 1231. Therefore, the second coil 1252b and the second magnet 1251b can be positioned opposite each other. At least a portion of the second magnet 1251b can overlap the second coil 1252b in the second direction (Y-axis direction). Similarly, at least a portion of the second coupling member 1254b can overlap the second coil 1252b in the second direction (Y-axis direction).

[0482] Furthermore, the first coil 1252a and the second coil 1252b can overlap in the second direction (Y-axis direction), and the first magnet 1251a and the second magnet 1251b can overlap in the second direction (Y-axis direction). Due to this configuration, the electromagnetic force applied to the outer surfaces of the retainer (the outer surfaces of the first and second retainers) is positioned along an axis parallel to the second direction (Y-axis direction), and thus X-axis tilting can be performed precisely and accurately.

[0483] Furthermore, as described above, the first Hall sensor 1253a and the second Hall sensor 1253b can be positioned externally for electrical connection and coupling to the substrate portion 1255. However, the positions of the first Hall sensor 1253a and the second Hall sensor 1253b are not limited thereto.

[0484] Furthermore, the third coil 1252c can be positioned on the third housing side 1223, and the third magnet 1251c can be positioned on the third retainer outer surface 1231S3 of the retainer 1231. At least a portion of the third coil 1252c and the third magnet 1251c can overlap in the first direction (X-axis direction). Therefore, the magnitude of the electromagnetic force between the third coil 1252c and the third magnet 1251c can be easily controlled.

[0485] As described above, the rotating plate 1240 can be positioned between the fourth outer surface 1231S4 of the retainer 1231 and the plate cover 1233 (or the fourth housing side 1224).

[0486] A first receiving groove PG1, positioned in the central portion in the second direction (Y-axis direction), and a second receiving groove PG2, positioned above and below the first receiving groove PG1, can be disposed in the outer surface 1231S4 of the fourth retainer. That is, the rotating plate 1240 can be disposed in the receiving groove PG of the outer surface 1231S4 of the fourth retainer. In other words, the rotating plate 1240 can be positioned in the first receiving groove PG1 and the second receiving groove PG2.

[0487] Furthermore, the rotating plate 1240 can be positioned in the first plate groove 1233g1 and the second plate groove 1233g2. However, a portion of the second protrusion PR2 can be positioned in the aforementioned first protrusion receiving groove and second protrusion receiving groove.

[0488] Furthermore, the base BS can be positioned within the third receiving region PG1c and the third plate region 1233g1c. Additionally, the first base protrusion PRB1 of the first protrusion PR1 can be positioned within the first receiving region PG1a and the first plate region 1233g1a. Furthermore, the first base protrusion PRB1 of the first protrusion PR1 can be positioned within the second receiving region PRG1b and the second plate region 1233g1b.

[0489] In this embodiment, the bottom surface LS of the first receiving groove PG1 can be configured to be separated from the base BS, the first base protrusion PRB1, and the second base protrusion PRB2 in the third direction (Z-axis direction). Furthermore, the bottom surface of the first plate groove 1233g1 can be configured to be separated from the base BS, the first base protrusion PRB1, and the second base protrusion PRB2 in the third direction (Z-axis direction). Due to this configuration, because the space for the rotating plate 1240 to perform biaxial tilting between the retainer 1231 and the plate cover 1233 is ensured, biaxial tilting can be performed precisely.

[0490] In this embodiment, at least a portion of the side surface SS of the first receiving groove PG1 can overlap the base BS, the first base protrusion PRB1, and the second base protrusion PRB2 in the first direction (X-axis direction). Furthermore, at least a portion of the side surface of the first plate groove 1233g1 can overlap the base BS, the first base protrusion PRB1, and the second base protrusion PRB2 in the first direction (X-axis direction). Using this structure, the rotating plate 1240 can be separated from the retainer 1231 and the plate cover 1233 without being separated in the first direction (X-axis direction) or the second direction (Y-axis direction).

[0491] Furthermore, the second receiving groove PG2 can overlap the first base protrusion PRB1 and the base BS in the third direction (Z-axis direction). Additionally, the second plate groove 1233g2 can overlap the first base protrusion PRB1 and the base BS in the third direction (Z-axis direction).

[0492] Furthermore, the shape of the second receiving groove PG2 can correspond to the shape of the first extended protrusion PRP1. Therefore, the second receiving groove PG2 can have a circular shape on the plane, just like the first extended protrusion PRP1.

[0493] Furthermore, the shape of each of the first protrusion receiving groove G1 and the second protrusion receiving groove G2 can also correspond to the second extended protrusion PRP2. Therefore, each of the first protrusion receiving groove G1 and the second protrusion receiving groove G2 can have a circular shape like the second extended protrusion PRP2.

[0494] The length of the second receiving groove PG2 in the third direction (Z-axis direction) can be less than the length of the first receiving groove PG1 in the third direction (Z-axis direction).

[0495] Furthermore, at least a portion of the second receiving groove PG2 can be separated from the first extended protrusion PRP1 by a predetermined distance. Therefore, it can be ensured that the retainer 1231 and the cover 1233 can perform tilting (first axis tilting) relative to the second direction (Y-axis direction) within the space.

[0496] Furthermore, the first protrusion receiving groove G1 and the second protrusion receiving groove G2 can be separated from the second extended protrusion PRP2 by a predetermined distance. Therefore, it can be ensured that the retainer 1231 and the cover 1233 can perform tilting (second axis tilting) relative to the first direction (X-axis direction) within the space.

[0497] In other words, the separation spaces gg1, gg2, gg3, and gg4 can exist between the base BS and the retainer 1231 or between the base BS and the cover 1233. Therefore, when performing two-axis tilting, since the base BS of the rotating plate 1240 does not contact the retainer 1231 or the cover 1233, two-axis tilting can be easily performed.

[0498] Figure 22 The diagram is in Figure 21a An exemplary view of the movement of the second camera actuator illustrated in the figure, and Figure 23 It is a diagram. Figure 21c An exemplary view of the movement of the second camera actuator illustrated in the figure.

[0499] refer to Figure 22 It can perform Y-axis tilting. That is, rotation can be performed in the first direction (X-axis direction) to implement OIS.

[0500] In an embodiment, the third magnet 1251c and the third coil 1252c disposed at the lower part of the retainer 1231 can generate an electromagnetic force to tilt or rotate the mover 1230 in a first direction (X-axis direction). That is, by means of the aforementioned electromagnetic force, the retainer 1231 and the cover plate 1233 coupled to the retainer 1231 can move in the first direction (X-axis direction).

[0501] Furthermore, the rotating plate 1240 can rotate or tilt based on a second protrusion PR2 (e.g., a second extended protrusion) that extends in the second direction and serves as a reference axis (or rotation axis). That is, the rotating plate 1240 can perform Y-axis tilting (or first axis tilting) based on the second protrusion PR2 that serves as a reference axis.

[0502] For example, OIS can be performed when the mover 1230 is rotated (X1->X1a or X1->X1b) by a first angle θ1 in the X-axis direction by the first electromagnetic forces F1A and F1B between the third magnet 1251c disposed in the third mounting slot and the third coil 1252c disposed on the side of the third substrate. The first angle θ1 can be in the range of ±1° to ±3°. However, the present invention is not limited thereto.

[0503] refer to Figure 23 It can perform X-axis tilt. That is, rotation can be performed in the second direction (Y-axis direction) to implement OIS.

[0504] OIS can be achieved when the mover 1230 tilts or rotates (or tilts the X-axis) in the Y-axis direction.

[0505] In this embodiment, the first magnet 1251a and the second magnet 1251b disposed in the retainer 1231, together with the first coil 1252a and the second coil 1252b, can generate an electromagnetic force to tilt or rotate the rotating plate 1240 and the mover 1230 in a second direction (Y-axis direction). That is, through the aforementioned electromagnetic force, the retainer 1231 and the plate cover 1233 coupled to the retainer 1231 can rotate or move in the second direction (Y-axis direction).

[0506] The rotating plate 1240 can rotate or tilt in a second direction (X-axis tilt) based on the first protrusion PR1 (e.g., the first extended protrusion) which serves as a reference axis (or rotation axis).

[0507] For example, OIS can be achieved when the mover 1230 is rotated in the Y-axis direction (Y1->Y1a or Y1->Y1b) by a second angle θ2 through the second electromagnetic forces F2A and F2B between the first magnet 1251a and the second magnet 1251b disposed in the first mounting slot and the first coil 1252a and the second coil 1252b disposed on the side of the first substrate and the side of the second substrate. The second angle θ2 can be in the range of ±1° to ±3°. However, the present invention is not limited thereto.

[0508] As described above, when OIS is achieved by controlling the rotating plate 1240 and the mover 1230 to rotate in a first direction (X-axis direction) or a second direction (Y-axis direction) using the electromagnetic force between the drive magnet in the holder and the drive coil disposed in the housing, the second camera actuator according to the embodiment can minimize downsloping or tilting phenomena to provide optimal optical properties. Furthermore, as described above, the term "Y-axis tilt" corresponds to rotation or tilt in the first direction (X-axis direction), and the term "X-axis tilt" corresponds to rotation or tilt in the second direction (Y-axis direction).

Figure 27a This is a perspective view of the first lens assembly in the actuator according to an embodiment, as illustrated in Figure 26. Figure 27b The diagram is in Figure 27a The diagram shows a perspective view of the state in which some components have been removed from the first lens assembly.

[0510] Figure 24 This is a perspective view illustrating an AF or zoom actuator according to yet another embodiment of the present invention. Figure 25 The diagram is in Figure 24 The diagram shows a perspective view of the state of some components omitted from the actuator according to an embodiment, and... Figure 26 The diagram is in Figure 24 The figure in the middle is an exploded perspective view of the state of some components of the actuator, which is omitted from the embodiment.

[0511] refer to Figure 24 According to the embodiment, the actuator 2100 may include a base 2020, a circuit board 2040 disposed outside the base 2020, a drive unit 2142, and a third lens assembly 2130.

[0512] Figure 25 It is from Figure 24 The actuator 2100 in the figure omits the perspective view of the base 2020 and the circuit board 2040, and refers to Figure 25 According to the embodiment, the actuator 2100 may include a first guide portion 2210, a second guide portion 2220, a first lens assembly 2110, a second lens assembly 2120, a drive portion 2141, and a drive portion 2142.

[0513] The drive unit 2141 and drive unit 2142 may include a coil or a magnet.

[0514] For example, when the drive unit 2141 and the drive unit 2142 include coils, the drive unit 2141 may include a first coil portion 2141b and a first magnetic yoke 2141a, and the drive unit 2142 may include a second coil portion 2142b and a second magnetic yoke 2142a.

[0515] Alternatively, drive unit 2141 and drive unit 2142 may also include a magnet.

[0516] refer to Figure 26 According to the embodiment, the actuator 2100 may include a base 2020, a first guide 2210, a second guide 2220, a first lens assembly 2110, a second lens assembly 2120, and a third lens assembly 2130.

[0517] 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 lens assembly 2110, a second lens assembly 2120 corresponding to the second guide portion 2220, and a first ball bearing 2117 disposed between the first guide portion 2210 and the first lens assembly 2110 (see...). Figure 27a ), and a second ball (not shown) disposed between the second guide portion 2220 and the second lens assembly 2120.

[0518] In addition, embodiments may include a third lens assembly 2130 disposed in front of the first lens assembly 2110 in the optical axis direction.

[0519] refer to Figure 25 and Figure 26 This embodiment may include: a first guide portion 2210, which is configured to be adjacent to a first sidewall of the base 2020; and a second guide portion 2220, which is configured to be adjacent to a second sidewall of the base 2020.

[0520] The first guide portion 2210 can be disposed between the first lens assembly 2110 and the first sidewall of the base 2020.

[0521] The second guide portion 2220 can be disposed between the second lens assembly 2120 and the second sidewall of the base 2020. The first and second sidewalls of the base 2020 can be arranged to face each other.

[0522] According to the embodiment, since the lens assembly is driven in a state where the first guide 2210 and the second guide 2220, which are precisely and digitally controlled in the base 2020, are coupled, the frictional torque is reduced to reduce frictional resistance, and therefore, when scaling is performed, there are technical effects of increased driving force, reduced power consumption, and improved control characteristics.

[0523] Therefore, according to the embodiments, when scaling is performed, even when the frictional torque is minimized, there is a sophisticated technical effect that significantly improves image quality or resolution by preventing phenomena such as lens downslant, lens tilt, or central axis misalignment between the lens group and the image sensor.

[0524] In particular, according to this embodiment, since the guide rail is not set on the base, and the first guide portion 2210 and the second guide portion 2220, which are formed separately and assembled with the base 2020, are used separately, there is a special technical effect of preventing the occurrence of gradients according to the injection direction.

[0525] In the embodiment, the first guide portion 2210 and the second guide portion 2220 are injected in the X-axis, and therefore the length of the injection can be less than the length of the base 2020. In this case, when a track is provided on each of the first guide portion 2210 and the second guide portion 2220, there is a technical effect that minimizes the occurrence of gradient and reduces the possibility that the straight line of the track is distorted during injection molding.

[0526] More specifically, Figure 27a The diagram is in Figure 26 The figure shows a perspective view of the first lens assembly 2110 in the actuator according to an embodiment. Figure 27b The diagram is in Figure 27a The diagram shows a perspective view of the state in which some components have been removed from the first lens assembly 2110.

The first lens barrel 2112a and the first drive housing 2112b may be a first housing, and the first housing may have the shape of a barrel or a lens barrel. The drive unit 2116 may be a drive magnet, but is not limited thereto, and in some cases, a coil may be provided.

[0529] Furthermore, the second lens assembly 2120 may include a second lens barrel (not shown) in which a second lens (not shown) is disposed, and a second drive housing (not shown) in which a drive unit (not shown) is disposed. The second lens barrel (not shown) and the second drive housing (not shown) may be a second housing, and the second housing may have a lens barrel shape. The drive unit may be a drive magnet, but is not limited thereto, and in some cases, a coil may be provided.

[0530] The drive unit 2116 can correspond to two first tracks 2212.

For example, embodiments may include a first ball 2117 disposed between the first guide 2210 and the first lens assembly 2110, and a second ball (not shown) disposed between the second guide 2220 and the second lens assembly 2120.

[0532] For example, in an embodiment, the first ball 2117 may include a single ball or a plurality of 1-1 balls 2117a disposed on the upper side of the first drive housing 2112b and a single ball or a plurality of 1-2 balls 2117b disposed on the lower side of the first drive housing 2112b.

[0534] According to the embodiment, since the first guide portion includes a 1-1 track and a 1-2 track, the 1-1 track and the 1-2 track guide the first lens assembly 2110, and thus there is a technical effect of improving the accuracy of the alignment of the second lens assembly 2120 with the optical axis when the first lens assembly 2110 moves.

[0535] refer to Figure 27b In one embodiment, the first lens assembly 2110 may include a first assembly groove 2112b1 in which a first ball 2117 is disposed. The second lens assembly 2120 may include a second assembly groove (not shown) in which a second ball is disposed.

[0536] The first component groove 2112b1 of the first lens assembly 2110 can be provided as a plurality of first component grooves 2112b1. In this case, among the plurality of first component grooves 2112b1, the distance between two first component grooves 2112b1 in the optical axis direction can be greater than the thickness of the first lens barrel 2112a.

[0537] In an embodiment, each of the first component grooves 2112b1 of the first lens assembly 2110 may be "V"-shaped. Furthermore, each of the second component grooves (not shown) of the second lens assembly 2120 may be "V"-shaped. The first component grooves 2112b1 of the first lens assembly 2110 may be "U"-shaped or have a shape that contacts each of the first balls 2117 at two or three points, rather than "V"-shaped. The second component grooves (not shown) of the second lens assembly 2120 may be "U"-shaped or have a shape that contacts each of the second balls at two or three points, rather than "V"-shaped.

[0538] refer to Figure 26 and Figure 27aIn one embodiment, the first guide portion 2210, the first ball bearing 2117, and the first component groove 2112b1 may be disposed on a virtual straight line extending from the first sidewall toward the second sidewall. The first guide portion 2210, the first ball bearing 2117, and the first component groove 2112b1 may be disposed between the first sidewall and the second sidewall.

[0541] In an embodiment, the third lens assembly 2130 includes a lens barrel recess 2021r at the upper end of the third lens barrel, and the resulting complex technical effect is that the thickness of the third lens barrel of the third lens assembly 2130 can be maintained constant and the amount of injected material is reduced to improve the accuracy of digital control.

[0542] Furthermore, according to an embodiment, the third lens assembly 2130 may include a housing rib 2021a and a housing recess 2021b in the third housing 2021.

[0543] In one embodiment, the third lens assembly 2130 includes a housing recess 2021b in the third housing 2021, and the resulting complex technical effect is to reduce the amount of injected material to improve the accuracy of digital control, while simultaneously ensuring rigidity by including housing ribs 2021a in the third housing 2021.

[0556] refer to Figure 30 The vehicle 700 in this embodiment may include wheels 13FL and 13FR, which are rotated by a power source; and predetermined sensors. Although the sensors may be camera sensors 2000, the invention is not limited thereto.

[0557] The camera sensor 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 obtain image information by capturing images of the front or surroundings through the camera sensor 2000, use the image information to determine situations where lane lines are not recognized, and generate virtual lane lines when lane lines are not recognized.

[0558] For example, camera sensor 2000 can obtain a frontal image by capturing an image in front of vehicle 700, and processor (not shown) can analyze objects included in the frontal image to obtain image information.

[0559] For example, when images of lanes, adjacent vehicles, obstacles, and median strips, curbs, roadside trees, etc., corresponding to indirect road signs are included in an image captured by the camera sensor 2000, the processor can detect such objects so that they are included in the image information. In this case, the processor can obtain distance information from the objects detected by the camera sensor 2000 to supplement the image information.

[0560] Image information can be information about objects captured in the image. The camera sensor 2000 may include an image sensor and an image processing module.

[0561] The camera sensor 2000 can process still or moving images obtained by an image sensor (e.g., complementary metal-oxide semiconductor (CMOS) or charge-coupled device (CCD)).

[0562] The image processing module can extract necessary information by processing still or moving images obtained through the image sensor and then transmit the extracted information to the processor.

[0563] In this case, the camera sensor 2000 may further include a stereo camera to improve the measurement accuracy of the object and further ensure information such as the distance between the vehicle 700 and the object, but is not limited thereto.
