[0111] When a certain component is described as being “connected” or “coupled” to another component, it should be understood that the certain component may be directly connected or coupled to the other component, or other components may be disposed between the certain component and the other component. On the other hand, when a certain component is described as being “directly connected” or “directly coupled” to another component, it should be understood that no other components are disposed between the certain component and the other component.

[0112] The terms used in this application are only used to describe specific embodiments and are not intended to limit the present disclosure. Unless the context clearly provides otherwise, singular expressions include plural expressions. In this application, it should be understood that terms such as "including" or "having" are intended to indicate the presence of features, numbers, steps, operations, components, parts, or combinations thereof described in this specification, but do not exclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

For example, terms defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning in the context of the relevant art, and should not be interpreted in an ideal or overly formal sense unless clearly defined in the present application.

[0114] Hereinafter, various embodiments will be described in detail with reference to the accompanying drawings, and the same or corresponding components are given the same reference numerals regardless of the reference numerals, and overlapping descriptions of the same or corresponding components will be omitted.

[0115] Figure 1 is a perspective view of a camera module according to an embodiment, Figure 2 is an exploded perspective view of a camera module according to an embodiment, and Figure 3 It is along Figure 1 Cross-sectional view along line AA'.

[0116] In the following, a view along a line corresponds to a view along the corresponding cutting surface.

[0117] Reference Figure 1 and Figure 2 , the camera module 1000 according to the embodiment may include a cover CV, a first camera actuator 1100, a second camera actuator 1200, and a circuit board 1300. Here, the first camera actuator 1100 may be used interchangeably with the "first actuator", and the second camera actuator 1200 may be used interchangeably with the "second actuator".

[0118] The cover CV may cover the first camera actuator 1100 and the second camera actuator 1200. The coupling strength between the first camera actuator 1100 and the second camera actuator 1200 may be increased by the cover CV.

[0119] In addition, the cover CV may be made of a material that blocks electromagnetic waves. Therefore, the first camera actuator 1100 and the second camera actuator 1200 in the cover CV may be easily protected.

[0120] In addition, the first camera actuator 1100 may be an optical image stabilizer (OIS) actuator. For example, the first camera actuator 1100 may move an optical member in a direction perpendicular to an optical axis (an axis of incident light).

[0121] The first camera actuator 1100 may include a fixed focal length lens disposed in a predetermined lens barrel (not shown). The fixed focal length lens may also be referred to as a “single focal length lens” or a “single lens”.

[0122] The first camera actuator 1100 can change the optical path. In an embodiment, the first camera actuator 1100 can change the optical path vertically by an internal optical component (e.g., a prism or a mirror). For example, the optical component can change the light from a first direction (X-axis direction) to a third direction (Z-axis direction). Alternatively, the optical component can change the light from a first axis to a second axis. Through this configuration, even when the thickness of the mobile terminal is reduced, a lens having a focal length greater than the thickness of the mobile terminal is disposed in the mobile terminal by a change in the optical path, so that auto focus (AF), zoom, and OIS functions can be performed.

[0123] However, the present disclosure is not limited thereto, and the first camera actuator 1100 may change the optical path vertically or a plurality of times at a predetermined angle.

[0124] The second camera actuator 1200 may be disposed at a rear end portion of the first camera actuator 1100. The second camera actuator 1200 may be coupled to the first camera actuator 1100. In addition, the mutual coupling may be performed by various methods.

[0125] In addition, the second camera actuator 1200 may be a zoom actuator or an AF actuator. For example, the second camera actuator 1200 may support one or more lenses to perform an AF function or a zoom function by moving the lenses according to a predetermined control signal of the controller.

[0126] Additionally, the lens or lenses may be independently or individually movable along the optical axis.

[0127] The circuit board 1300 may be provided at a rear end portion of the second camera actuator 1200. The circuit board 1300 may be electrically connected to the second camera actuator 1200 and the first camera actuator 1100. In addition, a plurality of circuit boards 1300 may be provided.

[0128] The camera module according to the embodiment may include one or more camera modules. For example, the plurality of camera modules may include a first camera module and a second camera module.

[0129] In addition, the first camera module may include one or more actuators. For example, the first camera module may include a first camera actuator 1100 and a second camera actuator 1200.

[0130] In addition, the second camera module may include an actuator (not shown) disposed in a predetermined housing (not shown) and capable of driving the lens unit. The actuator may be a voice coil motor, a microactuator, a silicon actuator, etc. and may be applied in various methods such as an electrostatic method, a thermal method, a dual piezoelectric chip method, and an electrostatic force method, but the present disclosure is not limited thereto. In addition, in the specification, the camera actuator may be referred to as an "actuator" or the like. In addition, a camera module including a plurality of camera modules may be installed in various electronic devices such as a mobile terminal. In addition, the actuator may be a device for moving or tilting a lens or an optical member. However, hereinafter, the actuator will be described as including a lens or an optical member. In addition, the actuator may be referred to as a "lens transfer device", a "lens moving device", an "optical member transfer device", an "optical member moving device", or the like.

[0131] Reference Figure 3 , a camera module according to an embodiment may include a first camera actuator 1100 for performing an OIS function and a second camera actuator 1200 for performing a zoom function and an AF function.

[0132] Light may enter the camera module or the first camera actuator through an opening area positioned in the upper surface of the first camera actuator 1100. That is, light may enter the first camera actuator 1100 along an optical axis direction (e.g., based on the X-axis direction of the incident light), and the optical path may be changed by an optical member (e.g., from the X-axis direction to the Z-axis direction). In addition, light may pass through the second camera actuator 1200 and may be incident on the image sensor IS positioned at one end of the second camera actuator 1200 (path). In this specification, the Z-axis direction or the third direction will be described as the optical axis direction as follows.

[0133] In this specification, the lower surface refers to a surface in the first direction. In addition, the first direction is the X-axis direction in the drawings and can be used interchangeably with the second axis direction, etc. The second direction is the Y-axis direction in the drawings and can be used interchangeably with the first axis direction, etc. The second direction is a direction perpendicular to the first direction. In addition, the third direction is the Z-axis direction in the drawings and can be used interchangeably with the third axis direction, etc. In addition, the third direction is perpendicular to both the first direction and the second direction. Here, the third direction (Z-axis direction) corresponds to the optical axis direction, and the first direction (X-axis direction) and the second direction (Y-axis direction) are directions perpendicular to the optical axis. In addition, hereinafter, the optical axis direction is the third direction (Z-axis direction) in the description of the second camera actuator 1200, and the description will be based on this below.

[0134] In addition, in the present specification, the inside may be a direction from the cover (CV) toward the first camera actuator, and the outside may be the opposite direction of the inside. That is, the first camera actuator and the second camera actuator may be positioned at the inside of the cover CV, and the cover CV may be positioned at the outside of the first camera actuator or the second camera actuator.

[0135] In addition, through this configuration, the camera module according to the embodiment can solve the space limitation of the first camera actuator and the second camera actuator by changing the optical path. That is, according to the change of the optical path, the camera module according to the embodiment can extend the optical path while minimizing the thickness of the camera module. In addition, it should be understood that the second camera actuator can provide a high magnification by controlling the focus in the extended optical path, etc.

[0136] In addition, the camera module according to the embodiment may implement OIS by controlling an optical path through the first camera actuator, thereby minimizing the occurrence of a decentering or tilting phenomenon and providing the best optical characteristics.

[0137] In addition, the second camera actuator 1200 may include an optical system and a lens driving unit. For example, at least one of a first lens assembly, a second lens assembly, and a third lens assembly may be provided in the second camera actuator 1200.

[0138] In addition, the second camera actuator 1200 may include coils and magnets to perform a high-magnification zoom function and an auto focus function.

[0139] For example, the first lens assembly and the second lens assembly may be moving lenses that each move through the coil, the magnet, and the guide pin, and the third lens assembly may be a fixed lens, but the present disclosure is not limited thereto. For example, the third lens assembly may perform the function of a focuser through which light forms an image at a specific position, and the first lens assembly may perform the function of a converter for re-forming the image formed by the third lens assembly as a focuser at another position. At the same time, since the distance to the object or image varies greatly, the first lens assembly may be in a state where the magnification changes greatly, and thus the first lens assembly as a converter may play an important role in the focal length or magnification change of the optical system. At the same time, the imaging point of the image formed by the first lens assembly as a converter may be slightly different depending on the position of the first lens assembly. Therefore, the second lens assembly may perform a position compensation function for the image formed by the converter. For example, the second lens assembly may perform the function of a compensator for accurately forming the imaging point of the image formed by the first lens assembly at the actual position of the image sensor as a converter. For example, the first lens assembly and the second lens assembly may be driven by the electromagnetic force generated by the interaction between the coil and the magnet. The above description can be applied to the lens assembly to be described below. In addition, the first lens assembly to the third lens assembly can be moved along the optical axis direction, that is, along the third direction. In addition, the first lens assembly to the third lens assembly can be moved independently or in relation to each other along the third direction. In the present disclosure, the first lens assembly and the second lens assembly can be moved along the optical axis direction. In addition, the third lens assembly can be positioned at the front end of the first lens assembly or at the rear end of the second lens assembly. In addition, the third lens assembly may not move along the optical axis direction. That is, the third lens assembly may be a fixed unit. In addition, the first lens assembly and the second lens assembly may be a mobile unit.

[0140] Meanwhile, when the OIS actuator and the AF / zoom actuator are provided according to an embodiment of the present disclosure, magnetic field interference with the AF / zoom magnet can be prevented when the OIS is driven. Since the first driving magnet of the first camera actuator 1100 is provided in a manner separated from the second camera actuator 1200, magnetic field interference between the first camera actuator 1100 and the second camera actuator 1200 can be prevented. In this specification, OIS may be used interchangeably with terms such as hand shake correction, optical image stabilizer, optical image correction, shake correction, and the like.

In addition, the first driving unit 1150 includes a driving magnet 1151, a driving coil 1152, a Hall sensor portion 1153, a first plate portion 1154, and a yoke portion 1155.

[0144] First, the first camera actuator 1100 may include a shield case (not shown). The shield case (not shown) may be positioned at the outermost side of the first camera actuator 1100 to surround a rotating unit 1140 and a first driving unit 1150 to be described below.

[0145] The shielding cover (not shown) may block or reduce electromagnetic waves generated from the outside. That is, the shielding cover (not shown) may reduce the occurrence of a malfunction in the rotating unit 1140 or the first driving unit 1150.

[0146] The first housing 1120 may be positioned inside a shield case (not shown). When the shield case is not present, the first housing 1120 may be positioned at the outermost side of the first camera actuator.

[0147] In addition, the first housing 1120 may be positioned at the inner side of a first plate portion 1154 to be described below. The first housing 1120 may be fastened by being fitted into a shield case (not shown) or engaged with the shield case.

[0148] The first housing 1120 may include a first housing side portion 1121, a second housing side portion 1122, a third housing side portion 1123, and a housing wall portion 1124. A detailed description of this will be given below.

[0150] In addition, the first camera actuator 1100 may further include a plate CP disposed at the outer side of the first member 1126. The plate CP may prevent foreign matter from passing through the first member 1126 and the like and flowing into the second member 1131a. In addition, the plate CP may be formed of a magnetic material. Therefore, since the plate CP has magnetism, a magnetic force may not be generated relative to the first magnetic portion 1143 and the second magnetic portion 1142 having polarity for pressing. That is, the generation of a magnetic force that interferes with the driving (pressing) of the first magnetic portion 1143 and the second magnetic portion 1142 may be reduced.

[0151] When the plate CP is a magnetic portion, the plate CP may be referred to as a magnetic member, a magnetic portion, a covering plate, a metal member, a metal plate, or the like.

[0152] The mover 1130 includes a holder 1131 and an optical member 1132 seated on the holder 1131 .

[0153] The retainer 1131 may be seated on the receiving portion 1125 of the first housing 1120. The retainer 1131 may include first to fourth retainer outer surfaces corresponding to the first housing side portion 1121, the second housing side portion 1122, the third housing side portion 1123, and the first member 1126, respectively. For example, the first to fourth retainer outer surfaces may correspond to or face the inner surface of the first housing side portion 1121, the inner surface of the second housing side portion 1122, the inner surface of the third housing side portion 1123, and the inner surface of the first member 1126, respectively.

[0154] In addition, the retainer 1131 may include a second member 1131a disposed in the fourth seating groove. The second member 1131a may be coupled to the retainer 1131 by passing through the first member 1126. The second member 1131a and the retainer 1131 may be coupled by any of various coupling members or coupling members. A detailed description of this will be given below.

[0155] The optical member 1132 may be seated on the holder 1131. To this end, the holder 1131 may have a seating surface, and the seating surface may be formed by a receiving groove. In an embodiment, the optical member 1132 may be formed by a mirror or a prism. Hereinafter, the optical member 1132 is illustrated as a prism, but may also be formed by a plurality of lenses. Alternatively, the optical member 1132 may include a plurality of lenses and a prism or a mirror. In addition, the optical member 1132 may include a reflector disposed therein. However, the present disclosure is not limited thereto.

[0156] In addition, the optical member 1132 can reflect light reflected from the outside (e.g., an object) into the camera module. That is, the optical member 1132 can reduce the space restriction on the first camera actuator and the second camera actuator by changing the path of the reflected light. Therefore, it should be understood that the camera module can provide a wide range of magnifications by extending the optical path while minimizing the thickness of the camera module.

[0157] Additionally, the second member 1131a may be coupled to the retainer 1131. The second member 1131a may be disposed at the outer side of the retainer 1131 and the inner side of the housing. In addition, the second member 1131a may be seated in an additional groove positioned in the retainer 1131 in an area other than the fourth seating groove located on the outer surface of the fourth retainer. Therefore, the second member 1131a may be coupled to the retainer 1131, and at least a portion of the first member 1126 may be positioned between the second member 1131a and the retainer 1131. For example, at least a portion of the first member 1126 may be disposed in a space formed between the second member 1131a and the retainer 1131. In addition, as described above, the second member 1131a may pass through a hole (a first through hole and a second through hole to be described below) formed in the first member 1126.

[0158] In addition, the second member 1131a may have a structure separated from the holder 1131. With this configuration, the assembly of the first camera actuator can be easily performed as will be described below. Alternatively, the second member 1131a may be formed integrally with the holder 1131, but will be described below as a separate structure.

[0159] The rotating unit 1140 includes an inclined guide portion 1141 , and second and first magnetic portions 1142 and 1143 having surfaces with the same polarity facing each other to press the inclined guide portion 1141 .

[0160] The inclined guide portion 1141 may be coupled to the mover 1130 and the first housing 1120. Specifically, the inclined guide portion 1141 may be disposed between the holder 1131 and the first member 1126. Therefore, the inclined guide portion 1141 may be coupled to the mover 1130 and the first housing 1120 of the holder 1131. However, unlike the above description, in an embodiment, the inclined guide portion 1141 may be disposed between the first member 1126 and the holder 1131. Specifically, the inclined guide portion 1141 may be positioned between the first member 1126 and the fourth seating groove of the holder 1131. For example, at least a portion of the inclined guide portion 1141 may be positioned in the fourth seating groove.

[0161] The second member 1131a, the first member 1126, the inclined guide portion 1141 and the retainer 1131 can be arranged in sequence along the third direction (Z-axis direction). In addition, the second magnetic portion 1142 and the first magnetic portion 1143 can be seated in the first groove gr1 formed in the second member 1131a and the second groove gr2 formed in the first member 1126, respectively. In an embodiment, the first groove gr1 and the second groove gr2 may have different positions from the first groove and the second groove described above in other embodiments. However, the first groove gr1 is positioned in the second member 1131a and moves integrally with the retainer and the second member 1131a, and the second groove gr2 is positioned on the first member 1126 corresponding to the first groove gr1 and is connected to the first housing 1120. Therefore, these terms will be used in an interchangeable manner. In addition, the first groove and the second groove may be grooves as described above. Alternatively, the first groove and the second groove may also be replaced by the form of holes.

[0162] In addition, the tilt guide portion 1141 may be disposed adjacent to the optical axis. Therefore, the actuator according to the embodiment may easily change the optical path according to the tilt of the first axis and the second axis to be described below.

[0163] The inclined guide portion 1141 may include a first protrusion disposed to be spaced apart from each other in a first direction (X-axis direction) and a second protrusion disposed to be spaced apart from each other in a second direction (Y-axis direction). In addition, the first protrusion and the second protrusion may protrude in opposite directions. A detailed description of this will be given below.

[0164] In addition, as described above, the second magnetic portion 1142 may be positioned in the second member 1131 a . In addition, the first magnetic portion 1143 may be positioned in the first member 1126 .

[0165] The second magnetic portion 1142 and the first magnetic portion 1143 may have surfaces with the same polarity facing each other. For example, the second magnetic portion 1142 may be a magnet with an N pole, and the first magnetic portion 1143 may be a magnet with an N pole. Alternatively, the second magnetic portion 1142 may be a magnet with an S pole, and the first magnetic portion 1143 may be a magnet with an S pole. For example, as described above, the first pole surface of the first magnetic portion 1143 and the second pole surface of the second magnetic portion 1142 facing the first pole surface may have the same polarity.

[0166] Due to the above polarity, the second magnetic part 1142 and the first magnetic part 1143 can generate a repulsive force therebetween. With this configuration, the above repulsive force can be applied to the second member 1131a or the retainer 1131 coupled to the second magnetic part 1142 and the first member 1126 or the first shell 1120 coupled to the first magnetic part 1143. In this case, the repulsive force applied to the second member 1131a can be transmitted to the retainer 1131 coupled to the second member 1131a. Therefore, the inclined guide part 1141 disposed between the second member 1131a and the first member 1126 can be pressed by the repulsive force. In addition, the repulsive force can also be transmitted to the shell and the mover. Therefore, the shell and the mover can be pressed by the repulsive force. That is, the repulsive force can correspond to the holding force of the position between the shell and the mover. That is, the repulsive force can keep the position of the inclined guide part 1141 between the retainer 1131 and the first shell 1120 (or the first member 1126). With this configuration, the position between the mover 1130 and the first housing 1120 can be maintained even during the X-axis tilt or the Y-axis tilt. In addition, the tilt guide portion can be in close contact with the first member 1126 and the holder 1131 by the repulsive force between the first magnetic portion 1143 and the second magnetic portion 1142. That is, the repulsive force generated by the first magnetic portion 1143 and the second magnetic portion 1142 can be a holding force for the position between the holder 1131 and the first housing 1120.

[0167] The first driving unit 1150 includes a driving magnet 1151, a driving coil 1152, a Hall sensor portion 1153, a first plate portion 1154, and a yoke portion 1155. A description of this will be given below. In addition, the yoke portion 1155 may be referred to as a "first yoke portion" in the first camera actuator. In addition, the yoke portion in the second camera actuator may be referred to as a "second yoke portion".

[0168] Figure 6a is a perspective view of a first housing of a first camera actuator according to an embodiment, Figure 6b The first housing of the first camera actuator is in contact with Figure 6a Stereoscopic images in different directions, Figure 6c is a front view of a first housing of a first camera actuator according to an embodiment, Figure 6d is a rear view of a first housing of a first camera actuator according to an embodiment, and Figure 6e is a top view of a first housing of a first camera actuator according to an embodiment.

[0169] Reference Figures 6a to 6e , the first housing 1120 according to the embodiment may include the first housing side portion 1121 to the third housing side portion 1123. In addition, the first member 1126 may be integrally formed by being coupled to the first housing 1120. Therefore, the first member 1126 may be a component included in the first housing 1120. Alternatively, the first housing 1120 may include the first member 1126.

[0170] The first housing side portion 1121 and the second housing side portion 1122 may be arranged to face each other. In addition, the first member 1216a and the housing wall portion 1124 may be arranged to face each other. In addition, the housing wall portion 1124 may also be similarly applied to a structure of a camera actuator in which the first member and the second member are not present. That is, even in a structure in which the mover is tilted within the housing, the fixed housing may include the housing wall portion.

[0171] In addition, the third case side portion 1123 may be disposed between the first case side portion 1121 and the second case side portion 1122 .

[0172] The third case side portion 1123 may be in contact with the first case side portion 1121 and the second case side portion 1122. In addition, the third case side portion 1123 may be a lower surface of the first case 1120. In addition, the above-described contents may also be applied to the description of directions in the same manner.

[0173] In addition, the first case side portion 1121 may include a first case hole 1121 a. A first coil to be described below may be positioned in the first case hole 1121 a.

[0174] In addition, the second housing side portion 1122 may include a second housing hole 1122a. In addition, a second coil 1152b to be described below may be positioned in the second housing hole 1122a.

[0175] In addition, the first case side portion 1121 and the second case side portion 1122 may be side surfaces of the first case 1120 .

[0176] The first coil and the second coil may be coupled to the first plate portion. In an embodiment, the first coil and the second coil may be electrically connected to the first plate portion so that current may flow through the first plate portion. The current is an element of the electromagnetic force capable of tilting the second camera actuator relative to the X-axis.

[0177] In addition, the third case side portion 1123 may include a third case hole 1123 a .

[0178] The third coil to be described below may be positioned in the third housing hole 1123a. In addition, the third coil 1152c may be electrically connected to the first plate portion in contact with the first housing 1120, and the third coil 1152c and the first plate portion may be coupled. Thus, the third coil may be electrically connected to the first plate portion to receive current from the first plate portion. Current is an element of the electromagnetic force capable of tilting the second camera actuator relative to the Y axis.

[0179] The first member 1126 may be seated between the first housing side portion 1121 and the third housing side portion 1123. Therefore, the first member 1126 may be positioned on the third housing side portion 1123. For example, the first member 1126 may be positioned at one side of the third housing side portion 1123. The first member 1126 and the retainer may be positioned sequentially along the third direction.

[0180] In addition, the first housing 1120 may include a receiving portion 1125 formed by the first housing side portion 1121 and the third housing side portion 1123. The first member 1126, the second member 1131a, and the mover 1130 as components may be positioned in the receiving portion 1125. The mover, the tilt guide, etc. may be positioned in the receiving portion 1125.

[0181] In addition, the first housing 1120 may further include a housing wall portion 1124 facing the first member 1126. In addition, the housing wall portion 1124 may be disposed between the first housing side portion 1121 and the second housing side portion 1122 and may contact the first housing side portion 1121, the second housing side portion 1122, and the third housing side portion 1123.

[0182] In addition, the housing wall portion 1124 can be positioned at the end of the first housing side portion 1121 and the end of the second housing side portion 1122. That is, a plurality of housing wall portions 1124 can be provided. In addition, a plurality of housing wall portions 1124 can be positioned on the first housing side portion 1121 and the second housing side portion 1122. A plurality of housing wall portions 1124 can be spaced apart from each other in the second direction (Y-axis direction). Therefore, the light reflected from the optical member 1132 can be moved to the second camera actuator positioned at the rear end of the first housing through the separation region. That is, the separation region provides a path for light movement.

[0183] In addition, the housing wall portion 1124 may include a protrusion, a groove, or the like for providing easy connection with another camera actuator (second camera actuator) adjacent to the housing wall portion 1124. With this configuration, the connection strength between the housing wall portion 1124 having an opening providing the optical path and another component can be improved while providing the optical path, thereby suppressing movement of the opening due to separation or the like to minimize changes in the optical path.

[0184] More specifically, the housing wall portion 1124 may be provided on a side portion corresponding to the emission surface of the optical member. In addition, the housing wall portion 1124 may be positioned between the first housing side portion 1121 and the second housing side portion 1122, and positioned at the end of the first housing side portion 1121 and the end of the second housing side portion 1122 in the optical axis direction. Therefore, the housing wall portion 1124 may be positioned at the rear end portion of the accommodating portion 1125 in the optical axis direction. In addition, the housing wall portion 1124 may be positioned at the rear end portion of the optical member in the optical axis direction (Z-axis direction).

[0185] In addition, the shell wall portion 1124 may overlap with the holder in the optical axis direction (Z-axis direction). In addition, at least a portion of the shell wall portion 1124 may overlap with the holder in the optical axis direction. Here, the optical axis direction (Z-axis direction) may correspond to the moving direction of the reflected light. In addition, the optical axis direction may correspond to a direction perpendicular to the emitting surface of the optical member. Therefore, for the anti-shake function, even when the mover, i.e., the holder, is tilted, the amount of movement may be limited by the shell wall portion 1124. In addition, the shell wall portion 1124 and the holder may collide with each other so that no impact occurs in the first member or the second member. Therefore, the reliability of the first member and the second member may be improved.

[0186] In addition, the housing wall portion 1124 may be formed integrally with the housing 1120. In addition, a portion of the housing wall portion 1124 may be made of an elastic material. In addition, an elastic member may be additionally provided on the housing wall portion 1124. Therefore, the impact applied to the retainer 1131 due to the collision between the housing wall portion 1124 and the retainer 1131 may be reduced.

[0187] In addition, according to an embodiment, the shell wall portion 1124 may include a wall portion 1124a facing (or corresponding to) the rear surface of the holder (or the emitting surface of the optical component) and a shell extension portion 1124b extending from the wall portion 1124a to the upper portion of the holder.

[0188] The wall portion 1124a may overlap with the holder in the optical axis direction (Z-axis direction). In addition, the housing extension 1124b may overlap with the holder in the first direction.

[0189] The wall portion 1124a may serve as a stopper for the tilting of the holder in the first direction or the second direction. That is, when the holder is tilted, the holder and the wall portion 1124a may collide with each other or may contact each other.

[0190] In addition, when the retainer moves in the first direction or performs a second axis tilt (e.g., vertical drive), the housing extension 1124b may collide with the retainer or may contact the retainer. That is, the housing extension 1124b can be used as a stopper for the movement of the retainer in the first direction. In addition, the third housing side portion 1123 can also perform a stopper function.

[0191] In addition, as described above, the first member 1126 may be a component coupled to the first housing 1120 and included in the first housing 1120. For example, the first member 1126 may be a structure integrally formed with or separated from the first housing 1120. Hereinafter, the first member 1126 will be described as a structure separated from the first housing 1120.

[0192] In addition, the first member 1126 may be disposed in the first housing 1120. Alternatively, the first member 1126 may be positioned in the first housing 1120.

[0193] In addition, the first member 1126 may be coupled to the first housing 1120. In an embodiment, the first member 1126 may be positioned between the first housing side portion 1121 and the second housing side portion 1122. In addition, the first member 1126 may be positioned on the third housing side portion 1123 and coupled to the first housing side portion to the third housing side portion.

[0194] In addition, the first stopper member 1121b may be positioned on the inner surface of the first housing side portion 1121. In addition, the second stopper member 1122b may be positioned on the inner surface of the second housing side portion 1122.

[0195] The first stop member 1121b and the second stop member 1122b can be positioned symmetrically about the first direction (X-axis direction). The first stop member 1121b and the second stop member 1122b can extend along the first direction (X-axis direction). With this configuration, even when the first member 1126 moves into the first housing 1120, the position of the first member 1126 can be maintained by the first stop member 1121b and the second stop member 1122b. In other words, the first stop member 1121b and the second stop member 1122b can maintain the position of the first member 1126 at one side of the first housing 1120.

[0196] In addition, the first stopper member 1121b and the second stopper member 1122b can fix the position of the first member 1126 to fix the position of the tilt guide portion between the first member 1126 and the mover, thereby eliminating factors causing errors such as vibration. Therefore, the first camera actuator according to the embodiment can accurately perform X-axis tilt and Y-axis tilt.

[0197] In addition, the spacing distance L2 between the first stopper member 1121b and the second stopper member 1122b in the second direction (Y-axis direction) may be less than the maximum length L1 of the first member 1126 in the second direction (Y-axis direction). Therefore, the first member 1126 may be assembled or inserted into the side surface of the first housing 1120 and coupled to the first housing 1120. In addition, the retainer may be assembled to the first housing 1120 along the first direction. In addition, as described above, the first member 1126 may be coupled to the first housing 1120 along the side surface of the first housing 1120, i.e., along the optical axis direction. In addition, the second member may be assembled or inserted into the first housing 1120 along the optical axis direction. Therefore, the second member may pass through the first member 1126. Thereafter, the plate may also be disposed on the first member 1126.

[0198] In addition, the first member 1126 includes a second protrusion groove PH2, in which the second protrusion of the inclined guide portion is seated. The second protrusion groove PH2 can be positioned in the inner surface 1126S1 of the first member 1126. As will be described below, the content of the first protrusion groove can be applied to the second protrusion groove PH2 in the same manner. For example, a plurality of second protrusion grooves PH2 can be formed, and the plurality of second protrusion grooves can have a structure that has the same or different contact points as the contact points of the second protrusion of the inclined guide portion. For example, the number of second protrusion grooves PH2 is two, and the second protrusion groove PH2 can have a 4-point or 8-point contact structure. That is, the second protrusion groove PH2 can have a plurality of inclined surfaces. In addition, the second protrusion groove PH2 can also be a hemispherical groove.

[0199] In addition, in the first member 1126, the protrusion (e.g., the second protrusion) of the tilt guide portion is disposed adjacent to the optical member (prism) in the fourth seating groove, so that the protrusion as the tilt reference axis is disposed adjacent to the center of gravity of the mover 1130. Therefore, when the holder is tilted, the moment for moving the mover 1130 for tilting can be minimized. Therefore, the current consumption for driving the coil can be minimized, thereby reducing the power consumption of the camera actuator.

[0200] In addition, the first member 1126 may include through holes 1126a and 1126b. A plurality of through holes may be formed, and the plurality of through holes may include the first through hole 1126a and the second through hole 1126b.

[0201] The first extension and the second extension of the second member described below can pass through the first through hole 1126a and the second through hole 1126b, respectively. Therefore, the holding force between the second member and the first member can be generated by the repulsive force between the first magnetic part and the second magnetic part. That is, even when the mover is tilted, the position between the first shell and the mover can be maintained.

[0202] The second protrusion groove PH2 may be positioned between the first through hole 1126a and the second through hole 1126b. With this configuration, the coupling strength between the tilt guide portion 1141 and the first member 1126 may be increased, thereby preventing a decrease in tilt accuracy caused by movement of the tilt guide portion 1141 in the first housing.

[0203] In addition, the second groove gr2 can be positioned on the outer surface 1126S2 of the first member 1126. The first magnetic part can be seated in the second groove gr2. In addition, the outer surface 1126S2 of the first member 1126 can be opposite to or facing the inner surface of the second member or the base part of the member. In addition, the second magnetic part seated on the second member and the first magnetic part of the first member 1126 can face each other and generate the above-mentioned repulsive force. Therefore, since the first member 1126 presses the inclined guide part inward or toward the retainer by the repulsive force, the mover can be spaced apart from the third shell side part in the first shell by a predetermined distance even if no current is injected into the coil. That is, the holding force for maintaining the position between the mover, the shell and the inclined guide part can be generated by the first magnetic part and the second magnetic part.

[0204] In addition, when the first member 1126 is integrally formed with the first housing 1120, the coupling strength between the first member 1126 and the first housing 1120 can be improved, thereby improving the reliability of the camera actuator. In addition, when the first member 1126 is separately formed from the first housing 1120, the ease of assembly and manufacturing of the first member 1126 and the first housing 1120 can be improved.

[0205] In addition, in an embodiment, the first member 1126 may include the first through hole 1126a and the second through hole 1126b as described above. In addition, the first through hole 1126a and the second through hole 1126b may be arranged side by side along the second direction (Y-axis direction) and may overlap each other.

[0206] In addition, the first member 1126 may include an upper member UA positioned above the first through hole 1126a and the second through hole 1126b and a lower member BA positioned below the first through hole 1126a and the second through hole 1126b. Therefore, the first through hole 1126a and the second through hole 1126b may be positioned in the middle of the first member 1126. That is, the first member 1126 may include a connecting member MA positioned at the side portion of the first through hole 1126a and the side portion of the second through hole 1126b. That is, the upper member UA and the lower member BA may be connected by the connecting member MA. In addition, a plurality of lower members BA may be formed to form the first through hole and the second through hole, and the plurality of lower members BA may be spaced apart from each other in the second direction (Y-axis direction).

[0207] Therefore, the first member 1126 may have an upper member UA, thereby improving the rigidity. For example, the rigidity of the first member 1126 may be increased compared to a case where the upper member UA does not exist. For example, in an embodiment, the unit of the rigidity may be N / μm. Therefore, the reliability of the first camera actuator according to an embodiment may be improved.

[0208] In addition, the first coupling groove 1126k may be positioned in the outer surface 1126S2 of the first member 1126. The first coupling groove 1126k may be positioned at an edge of the outer surface 1126S2 of the first member 1126. In particular, the first coupling groove 1126k may be positioned at ends (e.g., left and right sides) of the outer surface 1126S2 of the first member 1126 and positioned adjacent to the first housing side portion 1121.

[0209] The first coupling groove 1126k may be positioned to correspond to or face the second coupling groove 1121m of the first housing side portion 1121 and the second coupling groove 1122m of the second housing side portion 1122. In an embodiment, the first coupling groove 1126k may be positioned to correspond to (or face) the second coupling groove 1121m of the first housing side portion 1121 and the second coupling groove 1122m of the second housing side portion 1122. The second coupling grooves 1121m and 1122m may be adjacent to the outer surface 1126S2 of the first member 1126 and positioned on the same side surface.

[0210] In an implementation, a plurality of first coupling grooves 1126k and a plurality of second coupling grooves 1121m and 1122m may be formed and may be symmetrically positioned in the first direction or the second direction.

[0211] The coupling member may be applied to the first coupling groove 1126k and the second coupling grooves 1121m and 1122m. That is, the coupling member may be applied between the first housing side portion (or the second housing side portion) and the first member 1126, thereby increasing the coupling strength between the first housing 1120 and the first member 1126. The coupling member may include epoxy resin or the like, but is not limited to the material.

[0212] In addition, the first member 1126 may further include a first protrusion 1126c and a second protrusion 1126d. The first protrusion 1126c may contact the first housing side portion 1121, and the second protrusion 1126d may contact the second housing side portion 1122. The first protrusion 1126c may extend from one end of the outer surface 1126S2 of the first member along a third direction (Z-axis direction). The second protrusion 1126d may extend from the other end of the outer surface 1126S2 of the first member along a third direction (Z-axis direction). In other words, the first protrusion and the second protrusion may extend toward the retainer.

[0213] The position of the first protrusion may be maintained by the first stopper member 1121b, and the position of the second protrusion may be maintained by the second stopper member 1122b. Therefore, the reliability of the camera actuator according to the embodiment may be improved.

[0214] In addition, as described above, the housing wall portion 1124 according to the embodiment may include the wall portion 1124 a and the housing extension 1124 b .

[0215] The housing wall portion 1124 or the wall portion 1124a may overlap the first through hole 1126a and the second through hole 1126b of the first member 1126 in the optical axis direction (Z-axis direction). For example, the housing wall portion 1124 or the wall portion 1124a may partially overlap the first through hole 1126a and the second through hole 1126b of the first member 1126 in the optical axis direction (Z-axis direction).

[0216] In addition, the second protrusion groove PH2 may be positioned between adjacent wall portions 1124a. In addition, the housing wall portion 1124 or the wall portion 1124a may not overlap with the second protrusion groove PH2 in the optical axis direction (Z-axis direction).

[0217] With this configuration, it is possible to increase the effective area of ​​light emitted after being reflected by the optical member positioned between adjacent wall portions 1124a.

[0218] In addition, the distance between adjacent housing extensions 1124b (the spacing distance in the second direction) can be reduced in the optical axis direction. With this configuration, the amount of light incident on the optical member can be increased. In addition, the housing extension 1124b can be fully used as a stopper for the tilt of the retainer.

[0219] In addition, the third housing hole 1123a may be positioned between adjacent housing extensions 1124b. That is, the third housing hole 1123a and the housing extensions 1124b do not overlap each other in the first direction (X-axis direction) and may be misaligned.

[0220] Figure 7 is a perspective view of optical components of a first camera actuator according to an embodiment.

[0221] The optical member 1132 may be seated on the holder. The optical member 1132 may be a right angle prism as a reflector, but is not limited thereto.

[0222] In an embodiment, the optical member 1132 may have a protrusion (not shown) located on a portion of its outer surface. The optical member 1132 may be easily coupled to the holder through the protrusion (not shown). In addition, the holder may be coupled to the optical member 1132 through a groove or a protrusion.

[0223] In addition, the lower surface 1132b of the optical member 1132 may be seated on the seating surface of the holder. Therefore, the lower surface 1132b of the optical member 1132 may correspond to the seating surface of the holder. In addition, the lower surface 1132b of the optical member 1132 may be a reflective surface. In addition, the upper surface of the optical member 1132 may be an incident surface through which light is incident. In addition, the rear surface of the optical member 1132 may be an emission surface through which light is output.

[0224] In addition, in an embodiment, the lower surface 1132b may be formed of an inclined surface in the same manner as the seating surface of the holder. Therefore, the optical member 1132 may be prevented from being separated from the holder when the prism moves according to the movement of the holder.

[0225] In addition, a groove is formed on the lower surface 1132b of the optical member 1132, and a bonding member is applied to the groove, and thus the optical member 1132 can be coupled to the holder. Alternatively, the holder can also be coupled to the optical member 1132 by applying a bonding member to the groove or protrusion of the holder.

[0226] In addition, the protrusion of the holder may face the housing wall portion to be described below. In addition, the protrusion of the holder may overlap with the optical member 1132 in the optical axis direction. Therefore, in an embodiment, the protrusion of the holder may not overlap with the housing wall portion in the optical axis direction.

[0227] In addition, as described above, the optical member 1132 may have a structure capable of reflecting light reflected from the outside (e.g., an object) into the camera module. As in an embodiment, the optical member 1132 may be formed by a single mirror. In addition, the optical member 1132 can solve the space limitations of the first camera actuator and the second camera actuator by changing the path of the reflected light. Therefore, it should be understood that the camera module can provide a wide range of magnifications by extending the optical path while minimizing the thickness of the camera module. In addition, it should be understood that the camera module including the camera actuator according to the embodiment can provide a wide range of magnifications by extending the optical path while minimizing the thickness.

[0228] Figure 8a is a perspective view of a holder of a first camera actuator according to an embodiment, Figure 8b is a bottom view of a holder of a first camera actuator according to an embodiment, Figure 8c is a front view of a holder of a first camera actuator according to an embodiment, Figure 8d is a rear view of a second member of a first camera actuator according to an embodiment, and Figure 8e is a bottom view of a second member of a first camera actuator according to an embodiment.

[0229] Reference Figures 8a to 8e , the holder 1131 may include a seating surface 1131o on which the optical member 1132 is seated. The seating surface 1131o may be an inclined surface. In addition, the holder 1131 may include a stepped portion on the seating surface 1131o. In addition, the stepped portion of the holder 1131 may be coupled to a protrusion (not shown) of the optical member 1132.

[0230] The holder 1131 may include a plurality of outer surfaces. For example, the holder 1131 may include a first holder outer surface 1131S1, a second holder outer surface 1131S2, a third holder outer surface 1131S3, and a fourth holder outer surface 1131S4.

[0231] The first holder outer surface 1131S1 may be positioned to face the second holder outer surface 1131S2. That is, the first holder outer surface 1131S1 may be disposed symmetrically with the second holder outer surface 1131S2 with respect to the first direction (X-axis direction).

[0232] The first retainer outer surface 1131S1 can be positioned to correspond to the first housing side portion. That is, the first retainer outer surface 1131S1 can face the first housing side portion. In addition, the second retainer outer surface 1131S2 can be positioned to correspond to the second housing side portion. That is, the second retainer outer surface 1131S2 can be positioned to face the second housing side portion.

[0233] In addition, the first holder outer surface 1131S1 may include a first seating groove 1131S1a. In addition, the second holder outer surface 1131S2 may include a second seating groove 1131S2a. The first seating groove 1131S1a and the second seating groove 1131S2a may be symmetrically disposed with respect to the first direction (X-axis direction).

[0234] In addition, the first seating groove 1131S1a and the second seating groove 1131S2a can be arranged to overlap each other in the second direction (Y-axis direction). In addition, the first magnet 1151a can be arranged in the first seating groove 1131S1a, and the second magnet 1151b can be arranged in the second seating groove 1131S2a. The first magnet 1151a and the second magnet 1151b can also be arranged symmetrically about the first direction (X-axis direction). In this specification, it should be understood that the first magnet to the third magnet can be connected to the housing by a yoke or a combining member. The polarity of the first magnet and the polarity of the second magnet can be positioned opposite to each other. For example, the N pole and the S pole of the first magnet can be arranged in sequence along the third direction, and the S pole and the N pole of the second magnet can be arranged in sequence along the third direction. As a modified example, by adjusting the current injection or current direction of the first coil and the second coil, the polarity of the first magnet and the polarity of the second magnet can be positioned to be the same.

[0235] As described above, due to the positions of the first and second seating grooves and the first and second magnets, the electromagnetic force generated by each magnet is coaxially provided to the first holder outer surface S1131S1 and the second holder outer surface 1131S2. For example, the area applied to the first holder outer surface S1131S1 (e.g., the part where the electromagnetic force is the strongest) and the area applied to the second holder outer surface S1131S2 (e.g., the part where the electromagnetic force is the strongest) can be positioned on an axis parallel to the second direction (Y-axis direction). Therefore, the X-axis tilt can be accurately performed.

[0236] The first magnet 1151a may be disposed in the first seating groove 1131S1a, and the second magnet 1151b may be disposed in the second seating groove 1131S2a.

[0237] The third retainer outer surface 1131S3 may be in contact with the first retainer outer surface 1131S1 and the second retainer outer surface 1131S2, and may be an outer surface extending from one side of the first retainer outer surface 1131S1 and the second retainer outer surface 1131S2 along the second direction (Y-axis direction). In addition, the third retainer outer surface 1131S3 may be positioned between the first retainer outer surface 1131S1 and the second retainer outer surface 1131S2. The third retainer outer surface 1131S3 may be the lower surface of the retainer 1131. That is, the third retainer outer surface 1131S3 may be positioned to face the third shell side portion.

[0238] In addition, the third holder outer surface 1131S3 may include a third seating groove 1131S3a. The third magnet may be positioned in the third seating groove 1131S3a. The third holder outer surface 1131S3 may be positioned to face the third housing side portion 1123.

[0239] In addition, at least a portion of the third housing hole 1123a may overlap with the third seating groove 1131S3a in the first direction (X-axis direction). Therefore, the third magnet in the third seating groove 1131S3a and the third coil in the third housing hole 1123a may be positioned to face each other. In addition, the third magnet and the third coil may generate an electromagnetic force so that the second camera actuator may perform Y-axis tilt.

[0240] In addition, the X-axis tilt may be performed by a plurality of magnets (the first magnet and the second magnet), while the Y-axis tilt may be performed only by the third magnet.

[0241] In an embodiment, the third seating groove 1131S3a may have a larger space than the first seating groove 1131S1a or the second seating groove 1131S2a. Through this configuration, the Y-axis tilt may be performed using current control similar to that of the X-axis tilt.

[0242] The fourth retainer outer surface 1131S4 may be in contact with the first retainer outer surface 1131S1 and the second retainer outer surface 1131S2, and may be an outer surface extending from one side of the first retainer outer surface 1131S1 and the second retainer outer surface 1131S2 along the first direction (X-axis direction). In addition, the fourth retainer outer surface 1131S4 may be positioned between the first retainer outer surface 1131S1 and the second retainer outer surface 1131S2. That is, the fourth retainer outer surface 1131S4 may be positioned to face the first member.

[0243] The fourth retainer outer surface 1131S4 may include a fourth seating groove 1131S4a. The inclined guide portion 1141 may be positioned in the fourth seating groove 1131S4a. In addition, the second member 1131a and the first member 1126 may be positioned in the fourth seating groove 1131S4a. In addition, the fourth seating groove 1131S4a may include a plurality of regions. The fourth seating groove 1131S4a may include a first region AR1, a second region AR2, and a third region AR3.

[0244] The second member 1131a may be positioned in the first area AR1. That is, the first area AR1 may overlap with the second member 1131a in the first direction (X-axis direction). In particular, the first area AR1 may be an area where the member base portion of the second member 1131a is positioned. In this case, the first area AR1 may be positioned on the fourth retainer outer surface 1131S4. That is, the first area AR1 may correspond to an area positioned above the fourth seating groove 1131S4a. In this case, the first area AR1 may not be an area in the fourth seating groove 1131S4a.

[0245] The first member 1126 may be positioned in the second area AR2. That is, the second area AR2 may overlap with the first member 1126 in the first direction (X-axis direction).

[0246] In addition, like the first area, the second area AR2 may be positioned on the fourth holder outer surface 1131S4. That is, the second area AR2 may correspond to an area positioned above the fourth seating groove 1131S4a.

[0247] The inclined guide portion may be positioned in the third area AR3. Specifically, the base of the inclined guide portion may be positioned in the third area AR3. That is, the third area AR3 may overlap with the inclined guide portion (eg, the base) in the first direction (X-axis direction).

[0248] In addition, the second area AR2 may be positioned between the first area AR1 and the third area AR3.

[0249] In addition, the second member may be disposed in the first area AR1, and the second member 1131a may include a first groove gr1. In an embodiment, the second member 1131a may include a first groove gr1 formed on the inner surface 1131aas. In addition, the second magnetic portion may be disposed in the first groove gr1 as described above.

[0250] In addition, as described above, the first member may be disposed in the second area AR2. The first groove gr1 may be positioned to face the second groove gr2. For example, at least a portion of the first groove gr1 may overlap with the second groove gr2 in the third direction (Z-axis direction).

[0251] In addition, the repulsive force generated by the second magnetic part may be transferred through the second member to the fourth seating groove 1131S4a of the holder 1131. Therefore, the holder may apply a force to the inclined guide portion in the same direction as the repulsive force generated by the second magnetic part.

[0252] The first member may include a second groove gr2 facing the first groove gr1 formed in the outer surface thereof. In addition, the first member may include a second protrusion groove formed on the inner surface thereof as described above. In addition, the second protrusion may be seated in the second protrusion groove.

[0253] In addition, similar to the second magnetic part, the repulsive force generated by the first magnetic part and the second magnetic part may be applied to the first member. Therefore, the first member and the second member may press the inclined guide part provided between the first member and the holder 1131 by the repulsive force.

[0254] The inclined guide portion 1141 may be provided in the third area AR3.

[0255] In addition, the first protrusion groove PH1 can be positioned in the fourth seating groove 1131S4a. In addition, the first protrusion of the inclined guide portion 1141 can be accommodated in the first protrusion groove PH1. Therefore, the first protrusion PR1 can be in contact with the first protrusion groove. The maximum diameter of the first protrusion groove PH1 can correspond to the maximum diameter of the first protrusion PR1. This can be applied to the second protrusion groove and the second protrusion PR2 in the same manner. That is, the maximum diameter of the second protrusion groove can correspond to the maximum diameter of the second protrusion PR2. Therefore, the second protrusion can be in contact with the second protrusion groove. With this configuration, the first axis tilting can be easily performed based on the first protrusion, the second axis tilting can be easily performed based on the second protrusion, and the radius of the tilting can be improved.

[0256] In addition, in an embodiment, a plurality of first protrusion grooves PH1 may be formed. For example, any one of the first protrusion groove PH1 and the second protrusion groove PH2 may include a first-first protrusion groove PH1a and a first-second protrusion groove PH1b. Hereinafter, the first protrusion groove PH1 including the first-first protrusion groove PH1a and the first-second protrusion groove PH1b will be described. In addition, the following description may also be applied to the second protrusion groove PH2 in the same manner. For example, the second protrusion groove PH2 may include a second-first protrusion groove and a second-second protrusion groove, wherein the description of the first-first protrusion groove may be applied to the second-first protrusion groove, and the description of the first-second protrusion groove may be applied to the second-second protrusion groove.

[0257] The first-first protrusion groove PH1a and the first-second protrusion groove PH1b may be disposed side by side in the first direction (X-axis direction).The first-first protrusion groove PH1a and the first-second protrusion groove PH1b may have the same maximum area or different maximum areas.

[0258] The plurality of first protrusion grooves PH1 may have different numbers of inclined surfaces. For example, the first protrusion groove PH1 may include a groove lower surface and an inclined surface. In this case, the plurality of protrusion grooves may have different numbers of inclined surfaces. In addition, the area of ​​the lower surface of the protrusion groove may also be different.

[0259] For example, the first-first protrusion groove PH1a may include a first groove lower surface LS1 and a first inclined surface CS1. The first-second protrusion groove PH1b may include a second groove lower surface LS2 and a second inclined surface CS2.

[0260] In this case, the first groove lower surface LS1 and the second groove lower surface LS2 may have different areas. The area of ​​the first groove lower surface LS1 may be smaller than the area of ​​the second groove lower surface LS2.

[0261] In addition, the number of the first inclined surfaces CS1 contacting the first groove lower surface LS1 may be different from the number of the second inclined surfaces CS2. For example, the number of the first inclined surfaces CS1 may be greater than the number of the second inclined surfaces CS2.

[0262] With this configuration, it is possible to easily compensate for the assembly tolerance of the first protrusion seated in the first protrusion groove PH1. For example, since the number of the first inclined surfaces CS1 is greater than the number of the second inclined surfaces CS2, the first protrusion can contact more inclined surfaces, thereby more accurately maintaining the position of the first protrusion in the first-first protrusion groove PH1a.

[0263] Different from this, in the first-second protrusion groove PH1b, the number of inclined surfaces contacting the first protrusion may be smaller than that of the first-first protrusion groove PH1a, thereby easily adjusting the position of the first protrusion.

[0264] In an embodiment, the second inclined surfaces CS2 may be arranged to be spaced apart from each other in the second direction (Y-axis direction). In addition, the second groove lower surface LS2 may extend in the first direction (X-axis direction) so that the first protrusion may be easily moved in the first direction (X-axis direction) in a state of contact with the second inclined surface CS2. That is, the position of the first protrusion in the first-second protrusion groove PH1b may be easily adjusted. In addition, a lubricating member may be applied to the first protrusion groove PH1.

[0265] In addition, in this embodiment, the first area AR1, the second area AR2, and the third area AR3 may have different heights in the first direction (X-axis direction). In an embodiment, the first area AR1 may have a height greater than that of the second area AR2 and the third area AR3 in the first direction (X-axis direction). Therefore, a step portion may be positioned between the first area AR1 and the second area AR2.

[0266] In addition, the second member 1131a may include a first groove gr1. That is, the first groove gr1 may be positioned in the inner surface of the member base portion 1131aa. In addition, the second magnetic portion described above may be seated in the first groove gr1. In addition, a plurality of first grooves gr1 may be formed according to the number of second magnetic portions. That is, the number of first grooves gr1 may correspond to the number of second magnetic portions.

[0267] In addition, the second member 1131a may include a member base portion 1131aa, a first extension portion 1131ab, and a second extension portion 1131ac.

[0268] The member base portion 1131aa may be positioned at the outermost portion of the first camera actuator. The member base portion 1131aa may be positioned at the outer side of the first member. That is, the first member may be positioned between the member base portion 1131aa and the tilt guide portion.

[0269] The first extension portion 1131ab can extend from the edge of the component base portion 1131aa along the third direction (Z-axis direction). That is, the first extension portion 1131ab can extend from the component base portion 1131aa toward the retainer 1131. This also applies to the second extension portion 1131ac in the same manner. In addition, the second extension portion 1131ac can extend from the edge of the component base portion 1131aa along the third direction (Z-axis direction). In an embodiment, the first extension portion 1131ab and the second extension portion 1131ac can be positioned at the edge of the component base portion 1131aa along the second direction (Y-axis direction). In addition, the first extension portion 1131ab and the second extension portion 1131ac can be arranged between the upper member and the lower member.

[0270] Therefore, the second member 1131a may have a groove formed by the first extension 1131ab and the second extension 1131ac. That is, the groove may be positioned between the first extension 1131ab and the second extension 1131ac. Therefore, the first extension 1131ab and the second extension 1131ac may be connected only by the member base portion 1131aa. With this configuration, the second member 1131a may continuously receive the repulsive force generated by the second magnetic portion seated at the center of the member base portion 1131aa, particularly seated in the first groove gr1.

[0271] In addition, the first extension portion 1131ab can be spaced apart from the second extension portion 1131ac in the second direction (Y-axis direction) to form a separation space. The first member and the inclined guide portion can be seated in the separation space. In addition, the second magnetic portion and the first magnetic portion can be positioned in the separation space.

[0272] In addition, the first extension portion 1131ab and the second extension portion 1131ac may have the same length in the third direction (Z-axis direction). Therefore, the coupling strength, weight, etc. may be formed in a balanced manner so that the tilting of the holder may be accurately performed without tilting to one side.

[0273] In addition, the first extension 1131ab and the second extension 1131ac can be connected to the retainer. In the present specification, it should be understood that the connection can be performed by a coupling member other than the protrusion and groove structure described above. In an embodiment, the first extension 1131ab and the second extension 1131ac may include a third coupling groove 1131k formed in a third direction (Z-axis direction). In addition, a coupling protrusion 1131m may be positioned in the area where the first extension 1131ab and the second extension 1131ac in the fourth seating groove 1131S4a overlap in the third direction (Z-axis direction). The coupling protrusion 1131m may be positioned to correspond to the third coupling groove 1131k.

[0274] For example, a bonding member, such as epoxy resin, may be applied to the third coupling groove 1131k. In addition, the coupling protrusion 1131m may be inserted into the third coupling groove 1131k of the first extension 1131ab and the second extension 1131ac. With this configuration, the second member 1131a and the retainer 1131 may be coupled. In addition, the repulsive force applied to the second member 1131a may be transmitted to the retainer 1131 through this coupling.

[0275] However, as mentioned above, it will be appreciated that the positions of the protrusion and groove structures may also vary relative to each other.

[0276] Figure 9a is a perspective view of a tilt guide unit of a first camera actuator according to an embodiment, Figure 9b The first camera actuator is a tilt guide unit in contact with Figure 9a Stereoscopic images in different directions, and Fig.9c It is along Figure 9a View of the tilt guiding unit of the first camera actuator along line FF'.

[0277] The inclined guide portion 1141 according to the embodiment may include a base BS, a first protrusion PR1 protruding from a first surface 1141a of the base BS, and a second protrusion PR2 protruding from a second surface 1141b of the base BS. In addition, the first protrusion and the second protrusion may have opposite surfaces according to the structure, but will be described below based on the drawings. In addition, it should be understood that the first protrusion PR1 and the second protrusion PR2 may be formed integrally with the base BS, and as illustrated in the drawings, the first protrusion PR1 and the second protrusion PR2 may have a spherical shape similar to a spherical piece. In addition, the first protrusion PR1 and the second protrusion PR2 may not be a protrusion shape, but may be a spherical piece shape.

[0278] First, the base BS may include a first surface 1141a and a second surface 1141b opposite to the first surface 1141a. That is, the first surface 1141a may be spaced apart from the second surface 1141b in a third direction (Z-axis direction), and the first surface 1141a and the second surface 1141b may be outer surfaces opposite to or facing each other in the inclined guide portion 1141.

[0279] The inclined guide portion 1141 may include a first protrusion PR1 extending to one side on the first surface 1141a. According to an embodiment, the first protrusion PR1 may protrude from the first surface 1141a toward the holder. A plurality of first protrusions PR1 may be formed, and the plurality of first protrusions PR1 may include a first-first protrusion PR1a and a first-second protrusion PR1b.

[0280] The first-first protrusion PR1a and the first-second protrusion PR1b may be positioned side by side in the first direction (X-axis direction). That is, the first-first protrusion PR1a and the first-second protrusion PR1b may overlap in the first direction (X-axis direction). In addition, in an embodiment, the first-first protrusion PR1a and the first-second protrusion PR1b may be bisected by a virtual line extending in the first direction (X-axis direction).

[0281] In addition, each of the first-first protrusion PR1a and the first-second protrusion PR1b may have a predetermined curvature and have, for example, a hemispherical shape. In addition, the first-first protrusion PR1a and the first-second protrusion PR1b may contact the first groove of the housing at a point farthest from the first surface 1141a of the base BS.

[0282] In addition, the inclined guide portion 1141 may include a second protrusion PR2 extending to one side on the second surface 1141b. According to an embodiment, the second protrusion PR2 may protrude from the second surface 1141b toward the housing. In addition, in an embodiment, a plurality of second protrusions PR2 may be formed, and the plurality of second protrusions PR2 may include a second-first protrusion PR2a and a second-second protrusion PR2b.

[0283] The second-first protrusion PR2a and the second-second protrusion PR2b may be positioned side by side in the second direction (Y-axis direction). That is, the second-first protrusion PR2a and the second-second protrusion PR2b may overlap in the second direction (Y-axis direction). In addition, in an embodiment, the second-first protrusion PR2a and the second-second protrusion PR2b may be bisected by a virtual line extending in the second direction (Y-axis direction).

[0284] Each of the second-first protrusion PR2a and the second-second protrusion PR2b may have a curvature and have, for example, a hemispherical shape. In addition, the second-first protrusion PR2a and the second-second protrusion PR2b may contact the second member 1131a at a point spaced apart from the second surface 1141b of the base BS.

[0285] The first-first protrusion PR1a and the first-second protrusion PR1b can be positioned in the area between the second-first protrusion PR2a and the second-second protrusion PR2b in the second direction. According to an embodiment, the first-first protrusion PR1a and the first-second protrusion PR1b can be positioned at the center of the separation space between the second-first protrusion PR2a and the second-second protrusion PR2b in the second direction. With this configuration, the actuator according to the embodiment can have an angle of inclination of the X-axis in the same range relative to the X-axis. That is, the inclined guide portion 1141 can also provide the following range (e.g., positive / negative range): within this range, the retainer can be tilted along the X-axis relative to the X-axis based on the first-first protrusion PR1a and the first-second protrusion PR1b.

[0286] In addition, the second-first protrusion PR2a and the second-second protrusion PR2b can be positioned in the area between the first-first protrusion PR1a and the first-second protrusion PR1b in the first direction. According to an embodiment, the second-first protrusion PR2a and the second-second protrusion PR2b can be positioned at the center of the separation space between the first-first protrusion PR1a and the first-second protrusion PR1b in the first direction. With this configuration, the actuator according to the embodiment can have an angle of Y-axis inclination in the same range relative to the Y-axis. That is, the inclined guide portion 1141 and the retainer can similarly provide the following range (e.g., positive / negative range): within this range, the Y-axis inclination can be performed relative to the Y-axis based on the second-first protrusion PR2a and the second-second protrusion PR2b.

[0287] Specifically, the first surface 1141a may include a first outer line M1, a second outer line M2, a third outer line M3, and a fourth outer line M4. The first outer line M1 and the second outer line M2 may face each other, and the third outer line M3 and the fourth outer line M4 may face each other. In addition, the third outer line M3 and the fourth outer line M4 may be positioned between the first outer line M1 and the second outer line M2. In addition, the first outer line M1 and the second outer line M2 may be perpendicular to the first direction (X-axis direction), but the third outer line M3 and the fourth outer line M4 may be parallel to the first direction (X-axis direction).

[0288] In this case, the first protrusion PR1 can be positioned on the first virtual line VL1. Here, the first virtual line VL1 is a line that bisects the first outer line M1 and the second outer line M2. Alternatively, the first virtual line VL1 and the third virtual line VL1' are lines that bisect the base BS in the second direction (Y-axis direction). Therefore, the tilting guide portion 1141 can easily perform X-axis tilting through the first protrusion PR1. In addition, since the tilting guide portion 1141 performs X-axis tilting relative to the first virtual line VL1, the rotational force can be uniformly applied to the tilting guide portion 1141. Therefore, the X-axis tilting can be accurately performed and the reliability of the device can be improved.

[0289] In addition, the first-first protrusion PR1a and the first-second protrusion PR1b can be symmetrically arranged about the first virtual line VL1 and the second virtual line VL2. Alternatively, the first-first protrusion PR1a and the first-second protrusion PR1b can be symmetrically positioned based on the first center point. With this configuration, when performing X-axis tilting, the supporting force supported by the first protrusion PR1 can be applied to the upper side and the lower side in the same manner relative to the second virtual line VL2. Therefore, the reliability of the tilting guide part can be improved. Here, the second virtual line VL2 is a line that bisects the third outer line M3 and the fourth outer line M4. Alternatively, the second virtual line VL2 and the fourth virtual line VL2' are lines that bisect the base BS in the first direction (X-axis direction).

[0290] In addition, the first center point may be an intersection point of the first virtual line VL1 and the second virtual line VL2 Alternatively, according to the shape of the inclination guide portion 1141, the second center point may be a point corresponding to the center of gravity.

[0291] In addition, the second surface 1141b may include a fifth outer line M1', a sixth outer line M2', a seventh outer line M3', and an eighth outer line M4'. The fifth outer line M1' and the sixth outer line M2' may face each other, and the seventh outer line M3' and the eighth outer line M4' may face each other. In addition, the seventh outer line M3' and the eighth outer line M4' may be positioned between the fifth outer line M1' and the sixth outer line M2'. In addition, the fifth outer line M1' and the sixth outer line M2' may be perpendicular to the first direction (X-axis direction), but the seventh outer line M3' and the eighth outer line M4' may be parallel to the first direction (X-axis direction).

[0292] In addition, since the tilt guide portion 1141 performs Y-axis tilt with respect to the fourth virtual line VL2', the rotation force may be uniformly applied to the tilt guide portion 1141. Therefore, the Y-axis tilt may be accurately performed and the reliability of the device may be improved.

[0293] In addition, the second-first protrusion PR2a and the second-second protrusion PR2b can be symmetrically arranged on the fourth virtual line VL2' relative to the third virtual line VL1'. Alternatively, the second-first protrusion PR2a and the second-second protrusion PR2b can be symmetrically positioned based on the second center point. With this configuration, when performing Y-axis tilting, the supporting force supported by the second protrusion PR2 can be applied to the upper side and the lower side in the same manner relative to the fourth virtual line VL2'. Therefore, the reliability of the tilting guide part can be improved. Here, the third virtual line VL1' is a line that bisects the fifth outer line M1' and the sixth outer line M2'. In addition, the second center point can be the intersection of the third virtual line VL1' and the fourth virtual line VL2'. Alternatively, according to the shape of the tilting guide part 1141, the second center point can be a point corresponding to the center of gravity.

[0294] In addition, the distance DR2 between the first-first protrusion PR1a and the first-second protrusion PR1b in the first direction (X-axis direction) may be greater than the length of the second protrusion PR2 in the first direction (X-axis direction). Therefore, when X-axis tilting is performed based on the first-first protrusion PR1a and the first-second protrusion PR1b, resistance due to the second protrusion PR2 may be minimized.

[0295] Correspondingly, the distance ML2 between the second-first protrusion PR2a and the second-second protrusion PR2b in the second direction (Y-axis direction) may be greater than the length of the first protrusion PR1 in the second direction (Y-axis direction). Therefore, when Y-axis tilting is performed based on the second-first protrusion PR2a and the second-second protrusion PR2b, the resistance caused by the first protrusion PR1 may be minimized.

[0296] Fig.10 is a view illustrating a first driving unit of a first camera actuator according to an embodiment.

[0297] Reference Fig.10 , the first driving unit 1150 includes a driving magnet 1151 , a driving coil 1152 , a hall sensor portion 1153 , a first plate portion 1154 , and a yoke portion 1155 .

[0298] In addition, as described above, the driving magnet 1151 may include the first magnet 1151a, the second magnet 1151b, and the third magnet 1151c providing the driving force generated by the electromagnetic force. The first magnet 1151a, the second magnet 1151b, and the third magnet 1151c may each be positioned on the outer surface of the holder 1131.

[0299] In addition, the driving coil 1152 may include a plurality of coils. In an embodiment, the driving coil 1152 may include a first coil 1152a, a second coil 1152b, and a third coil 1152c.

[0300] The first coil 1152a can be positioned to face the first magnet 1151a. Therefore, as described above, the first coil 1152a can be positioned in the first housing hole 1121a of the first housing side portion 1121. In addition, the second coil 1152b can be positioned to face the second magnet 1151b. Therefore, as described above, the second coil 1152b can be positioned in the second housing hole 1122a of the second housing side portion 1122.

[0301] According to an embodiment, the second camera actuator can control the mover 1130 to rotate along the first axis (X-axis direction) or the second axis (Y-axis direction) by driving the electromagnetic force between the magnet 1151 and the coil 1152, thereby minimizing the occurrence of eccentricity or tilt when implementing OIS and providing optimal optical characteristics.

[0302] In addition, according to an embodiment, an ultra-thin and ultra-small camera actuator and a camera module including the same may be provided by implementing OIS with the aid of the inclined guide portion 1141 of the rotating unit 1140 disposed between the first housing 1120 and the mover 1130 to solve the size limitation of the actuator.

[0303] The first board portion 1154 may include a first board side portion 1154a, a second board side portion 1154b, and a third board side portion 1154c. The first board side portion 1154a corresponds to the second sub-board to be described below. The second board side portion 1154b corresponds to the third sub-board to be described below. In addition, the third board side portion 1154c corresponds to the first sub-board to be described below.

[0304] The first plate side portion 1154a and the second plate side portion 1154b may be disposed to face each other. In addition, the third plate side portion 1154c may be positioned between the first plate side portion 1154a and the second plate side portion 1154b.

[0305] In addition, the first plate side portion 1154a can be positioned between the first shell side portion and the shielding cover, and the second plate side portion 1154b can be positioned between the second shell side portion and the shielding cover. In addition, the third plate side portion 1154c can be positioned between the third shell side portion and the shielding cover, and can be the lower surface of the first plate portion 1154.

[0306] The first board side portion 1154a may be coupled to and electrically connected to the first coil 1152a. In addition, the first board side portion 1154a may be coupled to and electrically connected to the first Hall sensor 1153a.

[0307] The second plate side portion 1154b may be coupled to and electrically connected to the second coil 1152b. It should be understood that the second plate side portion 1154b may also be coupled to and electrically connected to the first Hall sensor.

[0308] The third plate side portion 1154c may be coupled to and electrically connected to the third coil 1152c. In addition, the third plate side portion 1154c may be coupled to and electrically connected to the second Hall sensor 1153b.

[0309] The yoke portion 1155 may include a third yoke 1155a, a fourth yoke 1155b, and a fifth yoke 1155c. The third yoke 1155a may be positioned in the first seating groove and coupled to the first magnet 1151a. In addition, the fourth yoke 1155b may be positioned in the second seating groove and coupled to the second magnet 1151b. In addition, the fifth yoke 1155c may be positioned in the third seating groove and coupled to the third magnet 1151c. The third yokes 1155a to the fifth yokes 1155c allow the first magnet 1151a to the third magnet 1151c to be easily seated in the first seating groove to the third seating groove and coupled to the housing.

[0310] Fig.11a is a perspective view of a first camera actuator according to an embodiment, Fig.11b It is along Fig.11a a view of the first camera actuator of line PP', and Fig.11c It is along Fig.11a View of the first camera actuator along line QQ'.

[0311] Reference Figures 11a to 11c , the first coil 1152a can be positioned on the first housing side portion 1121, and the first magnet 1151a can be positioned on the first holder outer surface 1131S1 of the holder 1131. Therefore, the first coil 1152a and the first magnet 1151a can be positioned to face each other. At least a portion of the first magnet 1151a can overlap with the first coil 1152a in the second direction (Y-axis direction).

[0312] In addition, the second coil 1152b can be positioned on the second housing side portion 1122, and the second magnet 1151b can be positioned on the second holder outer surface 1131S2 of the holder 1131. Therefore, the second coil 1152b and the second magnet 1151b can be positioned to face each other. At least a portion of the second magnet 1151b can overlap with the second coil 1152b in the second direction (Y-axis direction).

[0313] In addition, the first coil 1152a and the second coil 1152b may overlap in the second direction (Y-axis direction), and the first magnet 1151a and the second magnet 1151b may overlap in the second direction (Y-axis direction).

[0314] With this configuration, the electromagnetic force applied to the outer surfaces of the holder (the first holder outer surface and the second holder outer surface) can be positioned on an axis parallel to the second direction (Y-axis direction), and thus X-axis tilting can be performed accurately and precisely.

[0315] In addition, the second protrusions PR2a and PR2b of the tilt guide portion 1141 may contact the first member 1126 of the first housing 1120. The second protrusion PR2 may be seated in a second protrusion groove PH2 formed in one side surface of the first member 1126. In addition, when performing X-axis tilting, the second protrusions PR2a and PR2b may be a reference axis (or rotation axis) of the tilt. Therefore, the tilt guide portion 1141 and the mover 1130 may move in the second direction.

[0316] In addition, as described above, the first hall sensor 1153a may be positioned outside to be electrically connected and coupled to the first plate portion 1154. However, the present disclosure is not limited to this position.

[0317] In addition, the third coil 1152c can be positioned on the third housing side portion 1123, and the third magnet 1151c can be positioned on the third holder outer surface 1131S3 of the holder 1131. At least a portion of the third coil 1152c and the third magnet 1151c can overlap in the first direction (X-axis direction). Therefore, the strength of the electromagnetic force between the third coil 1152c and the third magnet 1151c can be easily controlled.

[0318] As described above, the inclined guide portion 1141 may be positioned on the fourth holder outer surface 1131S4 of the holder 1131. In addition, the inclined guide portion 1141 may be seated in the fourth seating groove 1131S4a of the fourth holder outer surface. As described above, the fourth seating groove 1131S4a may include the first area AR1, the second area AR2, and the third area AR3.

[0319] The second member 1131a may be disposed in the first area AR1, and the second member 1131a may include a first groove gr1 formed on an inner surface of the second member 1131a. In addition, as described above, the second magnetic portion 1142 may be disposed in the first groove gr1, and the repulsive force RF2 generated by the second magnetic portion 1142 may be transmitted to the fourth seating groove 1131S4a of the retainer 1131 through the second member 1131a (RF2'). Therefore, the retainer 1131 may apply a force to the inclined guide portion 1141 in the same direction as the repulsive force RF2 generated by the second magnetic portion 1142.

[0320] The first member 1126 may be disposed in the second area AR2. The first member 1126 may include a second groove gr2 facing the first groove gr1. In addition, the first member 1126 may include a second protrusion groove PH2 disposed on a surface corresponding to the second groove gr2. In addition, the repulsive force RF1 generated by the first magnetic portion 1143 may be applied to the first member 1126. Therefore, the first member 1126 and the second member 1131a may press the inclined guide portion 1141 disposed between the first member 1126 and the retainer 1131 by the repulsive forces RF1 and RF2' generated. Therefore, even after the retainer is tilted relative to the X-axis or Y-axis by the current applied to the first coil and the second coil or the third coil 1152c, the connection (or position) between the retainer 1131, the first shell 1120 and the inclined guide portion 1141 can be maintained.

[0321] The inclined guide portion 1141 may be disposed in the third area AR3. As described above, the inclined guide portion 1141 may include a first protrusion PR1 and a second protrusion PR2. In this case, the first protrusion PR1 and the second protrusion PR2 may also be disposed on the first surface 1141a and the second surface 1141b of the base BS, respectively. As described above, even in another embodiment to be described below, the first protrusion PR1 and the second protrusion PR2 may be differently positioned on the surface facing the base.

[0322] The first protrusion groove PH1 can be positioned in the fourth seating groove 1131S4a. In addition, the first protrusion PR1 of the tilting guide portion 1141 can be accommodated in the first protrusion groove PH1. Therefore, the first protrusion PR1 can be in contact with the first protrusion groove PH1. The maximum diameter of the first protrusion groove PH1 can correspond to the maximum diameter of the first protrusion PR1. This can be applied to the second protrusion groove PH2 and the second protrusion PR2 in the same manner. With this configuration, the first axis tilting can be easily performed based on the first protrusion PR1, the second axis tilting can be easily performed based on the second protrusion PR2, and the radius of the tilting can be improved.

[0323] In addition, the tilt guide portion 1141 can be arranged side by side with the second member 1131a and the first member 1126 in the third direction (Z-axis direction), and thus the tilt guide portion 1141 can overlap with the optical member 1132 in the first direction (X-axis direction). More specifically, in an embodiment, the first protrusion PR1 can overlap with the optical member 1132 in the first direction (X-axis direction). In addition, at least a portion of the first protrusion PR1 can overlap with the third coil 1152c or the third magnet 1151c in the first direction (X-axis direction). That is, in the camera actuator according to the embodiment, each protrusion as the central axis of the tilt can be positioned adjacent to the center of gravity of the mover 1130. Therefore, the tilt guide portion can be positioned adjacent to the center of gravity of the holder. Therefore, the camera actuator according to the embodiment can minimize the moment value for tilting the holder, and also minimize the consumption of the current applied to the coil, etc. to tilt the holder, thereby improving power consumption and improving device reliability.

[0324] In addition, the second magnetic portion 1142 and the first magnetic portion 1143 may not overlap with the third coil 1152c or the optical member 1132 in the first direction (X-axis direction). That is, in an embodiment, the second magnetic portion 1142 and the first magnetic portion 1143 may be arranged to be spaced apart from the third coil 1152c or the optical member 1132 in the third direction (Z-axis direction). Therefore, the magnetic force transmitted from the second magnetic portion 1142 and the first magnetic portion 1143 to the third coil 1152c can be minimized. Therefore, the camera actuator according to the embodiment can easily perform vertical drive (Y-axis tilt) and can minimize power consumption.

[0325] In addition, as described above, the second Hall sensor 1153b positioned at the inner side of the third coil 1152c can detect changes in magnetic flux, and thus can perform position sensing between the third magnet 1151c and the second Hall sensor 1153b. In this case, the offset voltage of the second Hall sensor 1153b can be changed according to the influence of the magnetic field generated by the second magnetic part 1142 and the first magnetic part 1143.

[0326] The first camera actuator according to the embodiment includes the second member 1131a, the second magnetic portion 1142, the first magnetic portion 1143, the first member 1126, the tilt guide portion 1141, and the holder 1131, which may be arranged in sequence based on the outermost surface thereof. However, since the second magnetic portion is positioned in the second member and the first magnetic portion is positioned in the first member, the second member, the first member, the tilt guide portion, and the holder may be arranged in sequence.

[0327] In addition, in an embodiment, the distance between the second magnetic portion 1142 and the first magnetic portion 1143 and the holder 1131 (or the optical member 1132) in the third direction may be greater than the distance from the inclined guide portion 1141. Therefore, the second Hall sensor 1153b below the holder 1131 may also be arranged to be spaced a predetermined distance from the second magnetic portion 1142 and the first magnetic portion 1143. Therefore, the influence of the magnetic field generated by the second magnetic portion 1142 and the first magnetic portion 1143 on the second Hall sensor 1153b can be minimized, thereby preventing the Hall voltage from being concentrated to a positive or negative value and saturated. That is, this configuration can allow the Hall electrode to have a range in which Hall calibration can be performed. In addition, the temperature is also affected by the electrode of the Hall sensor, and the resolution of the camera lens varies according to the temperature, but in an embodiment, the situation where the Hall voltage is concentrated to a positive or negative value can be prevented to compensate for the lens resolution accordingly, thereby easily preventing the reduction of the resolution.

[0328] In addition, a circuit for compensating for an offset relative to the output of the second Hall sensor 1153b (ie, the Hall voltage) can be easily designed.

[0329] In addition, according to an embodiment, some areas of the inclined guide portion 1141 may be positioned at the outer side of the fourth holder outer surface relative to the fourth holder outer surface of the holder 1131 .

[0330] In addition to the first protrusion PR1 and the second protrusion PR2, the inclined guide portion 1141 can be seated in the fourth seating groove 1131S4a based on the base. That is, the length of the base in the third direction (Z-axis direction) can be smaller than the length of the fourth seating groove 1131S4a in the third direction (Z-axis direction). With this configuration, miniaturization can be achieved.

[0331] In addition, the maximum length of the inclined guide portion 1141 in the third direction (Z-axis direction) can be greater than the length of the fourth seating groove 1131S4a in the third direction (Z-axis direction). Therefore, as described above, the end of the second protrusion PR2 can be positioned between the outer surface of the fourth retainer and the first member 1126. That is, at least a portion of the second protrusion PR2 can be positioned in a direction opposite to the third direction (Z-axis direction) compared to the retainer 1131. That is, the retainer 1131 can be spaced a predetermined distance from the end of the second protrusion PR2 (the portion in contact with the second protrusion groove) in the third direction (Z-axis direction).

[0332] In addition, the front surface 1131aes of the second member 1131a according to the embodiment may be spaced apart from the front surface 1126es of the first member 1126. In particular, the front surface 1131aes of the second member 1131a according to the embodiment may be positioned from the front surface 1126es of the first member 1126 along the third direction (Z-axis direction). Alternatively, the front surface 1131aes of the second member 1131a according to the embodiment may be positioned at the inner side of the front surface 1126es of the first member 1126. To this end, the first member 1126 may have a structure extending inwardly and bending. In addition, some areas of the second member 1131a may be positioned in a groove formed by the above-mentioned extending and bending structure of the first member 1126.

[0333] With this configuration, since the second member 1131a is positioned at the inner side of the first member 1126, it is possible to improve space efficiency and achieve miniaturization. In addition, even when driving (tilting or rotation of the mover 1130) by electromagnetic force is performed, the second member 1131a does not protrude to the outside of the first member 1126, and thus can block contact with nearby devices. Therefore, reliability can be improved.

[0334] In addition, a predetermined separation space may exist between the second magnetic portion 1142 and the first magnetic portion 1143. That is, the second magnetic portion 1142 and the first magnetic portion 1143 may face each other with the same polarity.

[0335] Fig.12a is a perspective view of a first camera actuator according to an embodiment, Figure 12b It is along Fig.12a a view of the first camera actuator in line SS', and Fig.12c It shows Figure 12b An exemplary view of the movement of the first camera actuator illustrated in FIG.

[0336] Reference Figures 12a to 12c , the Y-axis tilt can be performed by the first camera actuator according to the embodiment. That is, OIS can be implemented by rotating the first camera actuator in the first direction (X-axis direction).

[0337] In an implementation, the third magnet 1151 c disposed under the holder 1131 may generate an electromagnetic force with the third coil 1152 c to tilt or rotate the mover 1130 with respect to the second direction (Y-axis direction).

[0338] Specifically, the repulsive force between the second magnetic portion 1142 and the first magnetic portion 1143 may be transmitted to the second member 1131a and the first member 1126, and finally to the inclined guide portion 1141 disposed between the first member 1126 and the retainer 1131. Therefore, the inclined guide portion 1141 may be pressed by the mover 1130 and the first housing 1120 by the above-mentioned repulsive force.

[0339] In addition, the second protrusion PR2 may be supported by the first member 1126. In this case, in an embodiment, the tilting guide portion 1141 may be rotated or tilted based on the second protrusion PR2 protruding toward the first member 1126, that is, rotated or tilted in the second direction (Y-axis direction), and the second protrusion PR2 is a reference axis (or rotation axis). That is, the tilting guide portion 1141 may be rotated or tilted in the first direction (X-axis direction) based on the second protrusion PR2 protruding toward the first member 1126, and the second protrusion PR2 is a reference axis (or rotation axis).

[0340] For example, OIS may be implemented by rotating the mover 1130 by a first angle θ1 in the X-axis direction (X1→X1a) by first electromagnetic forces F1A and F1B between a third magnet 1151c disposed in a third seating groove and a third coil 1152c disposed on a third plate side portion.

[0341] Conversely, OIS may be achieved by rotating the mover 130 by a first angle θ1 in a direction opposite to the X-axis direction (X1→X1b) by first electromagnetic forces F1A and F1B between a third magnet 1151c disposed in a third seating groove and a third coil 1152c disposed on a third plate side portion.

[0342] The first angle θ1 may be in the range of ±1° to ±3°. However, the present disclosure is not limited thereto.

[0343] Hereinafter, in the first camera actuator according to various embodiments, the electromagnetic force may move the mover by generating a force in the direction, or may move the mover in the direction even when generating a force in another direction. That is, the direction of the electromagnetic force refers to the direction of the force generated by the magnet and the coil to move the mover. For example, the first electromagnetic forces F1A and F1B may act in the third direction or in the direction opposite to the third direction.

[0344] In addition, the center MC1 of the second magnetic portion 1142 and the center MC2 of the first magnetic portion 1143 may be arranged side by side in the third direction (Z-axis direction). That is, the center line TL1 connecting the center MC1 of the second magnetic portion 1142 and the center MC2 of the first magnetic portion 1143 may be parallel to the third direction (Z-axis direction).

[0345] In addition, the bisector TL2 that bisects the second protrusion PR2 and corresponds to the third direction (Z-axis direction) may be parallel to the center line TL1 (or bisector). That is, the bisector TL2 may be a line that bisects the second protrusion PR2 in the first direction (X-axis direction), and a plurality of bisectors TL2 may be formed.

[0346] In an embodiment, the bisector TL2 can be arranged to be spaced apart from the center line TL1 in the first direction (X-axis direction). The bisector TL2 can be positioned above the center line TL1. With this configuration, since the separation distance between the third coil 1152c and the third magnet 1151c can be increased, the holder can perform two-axis tilting more accurately. In addition, when no current is applied to the coil, the position of the holder can be maintained equally.

[0347] More specifically, since the center MC1 of the second magnetic part 1142 and the center MC2 of the first magnetic part 1143 are spaced apart from the bisector TL2 in the first direction (X-axis direction), the force (e.g., repulsive force) between the second magnetic part 1142 and the first magnetic part 1143 can act at a certain distance spaced apart from the bisector TL2 corresponding to the optical axis in the first direction (X-axis direction). In addition, momentum is generated in the mover 1130 by this force. However, when the center MC1 of the second magnetic part 1142 and the center MC2 of the first magnetic part 1143 are positioned on the bisector TL2, there is a problem that the position of the tilt guide part and the second magnetic part 1142 is not maintained after tilting during calibration. That is, in the camera actuator according to the embodiment, since the center MC1 of the second magnetic part 1142 and the center MC2 of the first magnetic part 1143 are not set on the bisector TL2, the position of the tilt guide part and the second magnetic part 1142 can be maintained after tilting or rotating.

[0348] In another embodiment, the center MC1 of the second magnetic portion 1142 and the center MC2 of the first magnetic portion 1143 may be disposed to be spaced apart from each other in the first direction (X-axis direction).

[0349] In addition, the center MC1 of the second magnetic portion 1142 and the center MC2 of the first magnetic portion 1143 may not be positioned on the bisector TL2. For example, the center MC1 of the second magnetic portion 1142 and the center MC2 of the first magnetic portion 1143 may be positioned above the bisector TL2.

[0350] Therefore, since the separation distance between the third coil 1152c and the third magnet 1151c increases, the holder can perform two-axis tilting more accurately. In addition, when no current is applied to the coil, the position of the holder can be equally maintained.

[0351] In addition, the second magnetic portion 1142 and the first magnetic portion 1143 may have different lengths in the first direction (X-axis direction).

[0352] In an embodiment, the area of ​​the second magnetic portion 1142 coupled to the second member 1131a and tilted together with the mover 1130 may be greater than the area of ​​the first magnetic portion 1143. For example, the length of the second magnetic portion 1142 in the first direction (X-axis direction) may be greater than the length of the first magnetic portion 1143 in the first direction (X-axis direction). In addition, the length of the second magnetic portion 1142 in the second direction (Y-axis direction) may be greater than the length of the first magnetic portion 1143 in the second direction (Y-axis direction). In addition, the first magnetic portion 1143 may be positioned in a virtual straight line extending the two ends of the second magnetic portion 1142 along a third direction.

[0353] With this configuration, when tilting or rotating, even when the magnetic part (e.g., the second magnetic part) at one side is tilted, it is possible to easily prevent the generation of forces other than the vertical force due to the tilt. That is, even when the second magnetic part is vertically tilted together with the mover 1130, the second magnetic part may not receive a force (e.g., a repulsive force or an attractive force) resisting the tilt from the first magnetic part 1143. Therefore, the driving efficiency can be improved.

[0354] Fig.13a It is along Fig.12a a view of the first camera actuator in line RR', and Fig.13b yes Fig.13a An exemplary view of the movement of the first camera actuator illustrated in FIG.

[0355] Reference Fig.13a and Fig.13b , X-axis tilting may be performed. That is, OIS may be implemented by tilting or rotating the mover 1130 in the Y-axis direction.

[0356] In an embodiment, the first and second magnets 1151a and 1151b disposed on the holder 1131 may form electromagnetic forces with the first and second coils 1152a and 1152b, respectively, and tilt or rotate the tilt guide portion 1141 and the mover 1130 relative to the first direction (X-axis direction).

[0357] Specifically, the repulsive force between the second magnetic portion 1142 and the first magnetic portion 1143 may be transmitted to the first member 1126 and the retainer 1131 and finally to the inclined guide portion 1141 disposed between the retainer 1131 and the first member 1126. Therefore, the inclined guide portion 1141 may be pressed by the mover 1130 and the first housing 1120 by the above-mentioned repulsive force.

[0358] In addition, the first-first protrusion PR1a and the first-second protrusion PR1b may be spaced apart from each other in the first direction (X-axis direction) and supported by the first protrusion groove PH1 formed in the fourth seating groove 1131S4a of the holder 1131. In addition, in an embodiment, the tilt guide portion 1141 may be rotated or tilted based on the first protrusion PR1 protruding toward the holder 1131 (for example, in the third direction), that is, rotated or tilted in the first direction (X-axis direction), the first protrusion PR1 being a reference axis (or rotation axis).

[0359] For example, OIS can be achieved by rotating the mover 1130 in the Y-axis direction at a second angle θ2 (Y1→Y1a) by means of a second electromagnetic force F2A and F2B between the first magnet 1151a and the second magnet 1151b disposed in the first seating groove and the first coil 1152a and the second coil 1152b disposed on the first plate side portion and the second plate side portion. In addition, OIS can be achieved by rotating the mover 1130 in the Y-axis direction at a second angle θ2 (Y1→Y1b) by means of a second electromagnetic force F2A and F2B between the first magnet 1151a and the second magnet 1151b disposed in the first seating groove and the first coil 1152a and the second coil 1152b disposed on the first plate side portion and the second plate side portion. The second angle θ2 may be in the range of ±1° to ±3°. However, the present disclosure is not limited thereto.

[0360] In addition, as described above, the electromagnetic force generated by the first magnet 1151a and the second magnet 1151b and the first coil 1152a and the second coil 1152b can act in a third direction or in a direction opposite to the third direction. For example, the electromagnetic force can be generated at the left side of the mover 1130 in the third direction (Z-axis direction) and act on the right side of the mover 1130 in a direction opposite to the third direction (Z-axis direction). Therefore, the mover 1130 can rotate relative to the first direction. Alternatively, the mover 130 can move in the second direction.

[0361] As described above, the second camera actuator according to the embodiment can control the mover 1130 to rotate along the first axis (X-axis direction) or the second axis (Y-axis direction) through the electromagnetic force between the driving magnet in the holder and the driving coil provided in the first shell, thereby minimizing the occurrence of eccentricity or tilt when implementing OIS and providing optimal optical characteristics. In addition, as described above, "Y-axis tilt" means rotating or tilting in the first direction (X-axis direction), and "X-axis tilt" means rotating or tilting in the second direction (Y-axis direction).

[0363] Reference Fig.14 and Fig.16 According to the embodiment, the second camera actuator 1200 may include a lens unit 1220, a second housing 1230, a second driving unit 1250, a rear end optical unit 1260, a second plate unit 1270, a coupling member 1280, a stopper unit ST, and a yoke unit YK. In addition, the second camera actuator 1200 may further include a second shielding case (not shown), an elastic unit (not shown), and a coupling member (not shown).

[0364] A second shield cover (not shown) can be positioned in a region (e.g., the outermost portion) of the second camera actuator 1200 and positioned to surround the components to be described below (the lens unit 1220, the second housing 1230, the second drive unit 1250, the rear end optical unit 1260, the second board unit 1270, and the image sensor).

[0365] In addition, the second camera actuator 1200 may be a component separate from the image sensor and the base component to be described below, or a concept including the image sensor and the base component. Hereinafter, the main board or circuit board 1300 separate from the second camera actuator 1200 will be described as including the image sensor and the base component.

[0366] The second shielding case (not shown) may block or reduce electromagnetic waves generated from the outside, thereby reducing the occurrence of malfunctions in the second driving unit 1250.

[0367] The lens unit 1220 may be positioned in a second shield case (not shown). The lens unit 1220 may be movable in a third direction (Z-axis direction or optical axis direction). Therefore, the above-mentioned AF function and zoom function may be performed.

[0368] In addition, the lens unit 1220 can be positioned in the second housing 1230. Therefore, at least a portion of the lens unit 1220 can be moved in the second housing 1230 along the optical axis direction or the third direction (Z-axis direction). In addition, the second housing 1230 (or the second-second housing) may further include a foreign body prevention member disposed on the outer surface of the corresponding side portion along the first direction (X-axis direction). In order to seat the foreign body prevention member in the second housing 1230, the second housing 1230 may further include an additional groove. Therefore, the durability and reliability of the second camera actuator can be improved. In addition, the foreign body prevention member can suppress the separation of the second-first housing.

[0369] Specifically, the lens unit 1220 may include a lens group 1221 and a moving assembly 1222 .

[0370] First, the lens group 1221 may include at least one lens. In addition, although a plurality of lens groups 1221 may be formed, hereinafter, description will be made based on one lens group.

[0371] The lens group 1221 may be coupled to the moving assembly 1222 to move in a third direction (Z-axis direction) by an electromagnetic force generated by a fourth magnet 1252 a and a fifth magnet 1252 b coupled to the moving assembly 1222 .

[0372] In an embodiment, the lens group 1221 may include a first lens group 1221a, a second lens group 1221b, and a third lens group 1221c. The first lens group 1221a, the second lens group 1221b, and the third lens group 1221c may be arranged in sequence in the optical axis direction. In addition, the lens group 1221 may further include a fourth lens group 1221d. The fourth lens group 1221d may be disposed at the rear end portion of the third lens group 1221c.

[0373] The first lens group 1221a may be fixedly coupled to the second-first housing. That is, the first lens group 1221a may not move in the optical axis direction.

[0374] The second lens group 1221b may be coupled to the first lens assembly 1222a to move in a third direction or an optical axis direction. The magnification adjustment may be performed by moving the first lens assembly 1222a and the second lens group 1221b.

[0375] The third lens group 1221c may be coupled to the second lens assembly 1222b to move in a third direction or optical axis direction. Focus adjustment or auto-focusing may be performed by moving the third lens group 1221c.

[0376] However, the present disclosure is not limited to the number of lens groups, and the fourth lens group 1221d may not exist, or an additional lens group other than the fourth lens group 1121d may be provided.

[0377] The moving assembly 1222 may include an opening area around the lens group 1221. The moving assembly 1222 may be used interchangeably with the lens assembly. In addition, the moving assembly 1222 may be coupled to the lens group 1221 by various methods. In addition, the moving assembly 1222 may include a groove in the side surface of the moving assembly 1222 and may be coupled to the fourth magnet 1252a and the fifth magnet 1252b by the groove. A coupling member or the like may be applied to the groove.

[0378] In addition, the moving assembly 1222 can be connected to an elastic unit (not shown) at the upper end and the rear end of the moving assembly 1222. Therefore, the moving assembly 1222 can be supported by the elastic unit (not shown) while moving in the third direction (Z-axis direction). In other words, the position of the moving assembly 1222 can be maintained in the third direction (Z-axis direction). The elastic unit (not shown) can be formed by various elastic elements such as leaf springs.

[0379] The moving assembly 1222 may be positioned in the second housing 1230 and may include a first lens assembly 1222a and a second lens assembly 1222b.

[0380] The area where the third lens group is seated in the second lens assembly 1222b can be positioned at the rear end of the first lens assembly 1222a. That is, the area where the third lens group 1221c is seated in the second lens assembly 1222b can be positioned between the area where the second lens group 1221b is seated in the first lens assembly 1222a and the image sensor.

[0381] Each of the first lens assembly 1222a and the second lens assembly 1222b can be seated at the inner side of the second-second housing. For example, the recessed portion in which the spherical piece is disposed in the first lens assembly 1222a can be positioned to face the first side portion. In addition, the recessed portion in which the spherical piece is disposed in the second lens assembly 1222b can be positioned to face the second side portion. A detailed description of this will be given below.

[0382] In addition, a second driving magnet may be seated on the outer surface of the first lens assembly 1222a and the second lens assembly 1222b. For example, the fifth magnet 1252b may be seated on the outer surface of the second lens assembly 1222b. The fourth magnet 1252a may be seated on the outer surface of the first lens assembly 1222a.

[0383] The second housing 1230 may be disposed between the lens unit 1220 and a second shield cover (not shown). In addition, the second housing 1230 may be disposed to surround the lens unit 1220.

[0384] The second housing 1230 may include a second-first housing 1231 and a second-second housing 1232. The second-first housing 1231 may be coupled to the first lens group 1221a and may also be coupled to the first camera actuator described above. The second-first housing 1231 may be positioned in front of the second-second housing 1232.

[0385] The second-first housing 1231 can be used interchangeably with the “first sub-housing” in the second housing. In addition, the second-second housing 1232 can be used interchangeably with the “second sub-housing” in the second housing. In addition, the second camera actuator or the second housing 1230 may include a coupling member BM (see FIG. 1 ) disposed between the first sub-housing and the second sub-housing. Fig.17a ). A detailed description of this will be given below.

[0386] In addition, the second-second housing 1232 may be positioned at a rear end portion of the second-first housing 1231. The lens unit 1220 may be seated inside the second-second housing 1232.

[0387] A hole may be formed in a side portion of the second housing 1230 (or the second-second housing 1232 ), and the fourth coil 1251 a and the fifth coil 1251 b may be disposed in the hole. The hole may be positioned to correspond to the above-mentioned groove of the moving component 1222 .

[0388] In an embodiment, the second housing 1230 (particularly, the second-second housing 1232) may include a first side portion 1232a and a second side portion 1232b. The first side portion 1232a and the second side portion 1232b may be positioned to correspond to each other. For example, the first side portion 1232a and the second side portion 1232b may be symmetrically arranged about a third direction. A second drive coil 1251 may be positioned on the first side portion 1232a and the second side portion 1232b. In addition, the second board unit 1270 may be seated on the outer surface of the first side portion 1232a and the second side portion 1232b. That is, a first plate 1271 may be positioned on the outer surface of the first side portion 1232a, and a second plate 1272 may be positioned on the outer surface of the second side portion 1232b.

[0389] In addition, as another example, a first guide groove and a second guide groove facing a recess of the first lens assembly 1222a (wherein a seating groove of the first spherical member and the second spherical member is seated) may be positioned in the first side portion. In addition, a first guide groove and a second guide groove facing a recess of the second lens assembly 1222b may be positioned in the second side portion. In this case, there may be a structure in which a separate member (e.g., a guide unit) including the first guide groove and the second guide groove is connected to the second-second housing 1232. However, in an embodiment, an integrated structure in which the first guide groove and the second guide groove are formed in the second-second housing 1232 will be described. In addition, as another example, the first guide unit and the second guide unit may be positioned to correspond to each other. For example, the first guide unit and the second guide unit may be positioned to face each other relative to a third direction (Z-axis direction). In addition, the first guide unit and the second guide unit may overlap each other at least partially in the second direction (Y-axis direction).

[0390] The first guide unit and the second guide unit may include at least one groove (e.g., a guide groove) or a recess. In addition, the first spherical member B1 or the second spherical member B2 may be seated in the groove or the recess. Therefore, the first spherical member B1 or the second spherical member B2 may move in the guide groove of the first guide unit or the guide groove of the second guide unit along the third direction (Z-axis direction).

[0391] Alternatively, the first spherical member B1 or the second spherical member B2 may move in the third direction along a track formed at an inner side of the first side portion 1232 a of the second housing 1230 or a track formed at an inner side of the second side portion 1232 b of the second housing 1230 .

[0392] Therefore, the first lens assembly 1222a and the second lens assembly 1222b may move in the third direction.

[0393] According to an embodiment, the first spherical member B1 may be disposed on an upper portion of the first lens assembly 1222a or the second lens assembly 1222b. In addition, the second spherical member B2 may be disposed on a lower portion of the first lens assembly 1222a or the second lens assembly 1222b. For example, the first spherical member B1 may be positioned above the second spherical member B2. Therefore, at least a portion of the first spherical member B1 may overlap with the second spherical member B2 in the first direction (X-axis direction) according to the position.

[0394] In addition, the second-second shell 1232 may include guide grooves GG1a and GG2a facing the first recess RS1. In addition, the second-second shell 1232 may include guide grooves GG1b and GG2b facing the second recess RS2. The guide grooves GG1a and GG2a and the guide grooves GG1b and GG2b may be grooves extending in a third direction (Z-axis direction). In addition, the guide grooves GG1a and GG2a and the guide grooves GG1b and GG2b may be grooves having different shapes. For example, the guide grooves GG1a and GG2a may be grooves having inclined side surfaces, and the guide grooves GG1b and GG2b may be grooves having side surfaces perpendicular to their lower surfaces.

[0395] The fourth magnet and the fourth coil may be positioned on the first side portion. In addition, the fifth magnet and the fifth coil may be positioned on the second side portion. In addition, the fifth magnet 1252b may be positioned to face the fifth coil 1251b. In addition, the fourth magnet 1252a may be positioned to face the fourth coil 1251a.

[0396] The elastic unit (not shown) may include a first elastic member (not shown) and a second elastic member (not shown). The first elastic member (not shown) may be coupled to the upper surface of the moving assembly 1222. The second elastic member (not shown) may be coupled to the lower surface of the moving assembly 1222. In addition, the first elastic member (not shown) and the second elastic member (not shown) may be formed by a leaf spring as described above. In addition, the first elastic member (not shown) and the second elastic member (not shown) may provide elasticity for moving the moving assembly 1222. However, the present disclosure is not limited to the above-mentioned positions, and the elastic unit may be provided at various positions.

[0397] In addition, the second drive unit 1250 can provide a driving force for moving the lens unit 1220 along a third direction (Z-axis direction). The second drive unit 1250 may include a second drive coil 1251 and a second drive magnet 1252. In addition, the second drive unit 1250 may also include a second Hall sensor portion. The second Hall sensor portion 1253 may include at least one fourth Hall sensor 1253a and may be positioned at the inner side or outer side of the second drive coil 1251.

[0398] The moving component may be moved in the third direction (Z-axis direction) by the electromagnetic force generated between the second driving coil 1251 and the second driving magnet 1252 .

[0399] The second driving coil 1251 may include a fourth coil 1251a and a fifth coil 1251b. The fourth coil 1251a and the fifth coil 1251b may be disposed in a hole formed in a side portion of the second housing 1230. In addition, the fourth coil 1251a and the fifth coil 1251b may be electrically connected to the second board unit 1270. Therefore, the fourth coil 1251a and the fifth coil 1251b may receive current, etc. through the second board unit 1270.

[0400] The second driving magnet 1252 may include a fourth magnet 1252a and a fifth magnet 1252b. The fourth magnet 1252a and the fifth magnet 1252b may be disposed in the above-mentioned groove of the moving component 1222 and positioned to correspond to the fourth coil 1251a and the fifth coil 1251b.

[0401] The rear end optical unit 1260 may include a lens such as glass.

[0402] The base unit or base member of the circuit board can be positioned between the lens unit 1220 and the image sensor IS. Components such as filters can be fixed to the base member. In addition, the base member can be arranged to surround the above-mentioned image sensor. With this configuration, the reliability of the device can be improved because the image sensor is protected from foreign matter, etc. However, some of the following drawings will be described with the above description removed. However, the present disclosure may not be limited to this structure.

[0403] In addition, the second camera actuator 1200 may be a zoom actuator and an AF actuator. For example, the second camera actuator 1200 may support one lens or a plurality of lenses and perform at least one of an AF function and a zoom function by moving the lens according to a predetermined control signal of the controller.

[0404] In addition, the second camera actuator can be a fixed zoom or a continuous zoom. For example, the second camera actuator can provide movement of the lens group 1221.

[0405] In addition, the second camera actuator may be formed by a plurality of lens assemblies. For example, in addition to the first lens assembly 1222a and the second lens assembly 1222b, at least one of a third lens assembly (not shown) and a guide pin (not shown) may be provided in the second camera actuator. In this regard, the above contents may be applied. Therefore, the second camera actuator may perform a high-power zoom function through a second drive unit. For example, the first lens assembly 1222a and the second lens assembly 1222b may be a moving lens that moves through a second drive unit and a guide pin (not shown), and the third lens assembly (not shown) may be a fixed lens, but the present disclosure is not limited thereto. For example, the third lens assembly (not shown) may perform the function of a focuser through which light forms an image at a specific position, and the first lens assembly may perform the function of a converter for causing the image formed by the third lens assembly (not shown) as a focuser to be reformed at another position. At the same time, because the distance to the object or image varies greatly, the first lens assembly can be in a state where the magnification varies greatly, and the first lens assembly as a converter can play an important role in the focal length or magnification variation of the optical system. At the same time, the imaging point of the image formed by the first lens assembly as a converter can be slightly different depending on the position of the first lens assembly. Therefore, the second lens assembly can perform a position compensation function for the image formed by the converter. For example, the second lens assembly can perform the function of a compensator for accurately forming the imaging point of the image formed by the first lens assembly at the actual position of the image sensor. However, the configuration of the embodiment will be described with reference to the following drawings.

[0406] The image sensor may be positioned at the inside or outside of the second camera actuator. In an embodiment, as illustrated, the image sensor may be positioned at the outside of the second camera actuator. For example, the image sensor may be positioned on a circuit board. The image sensor may receive light and convert the received light into an electrical signal. In addition, the image sensor may include a plurality of pixels in an array. In addition, the image sensor may be positioned on an optical axis.

[0407] The second plate unit 1270 may be in contact with the side portion of the second shell. For example, the second plate unit 1270 may be positioned on the outer surface (first side surface) of the first side portion and the outer surface (second side surface) of the second side portion of the second shell, in particular the second-second shell, and may be in contact with the first side surface and the second side surface.

[0408] The stopper unit ST includes a first stopper ST1 disposed at one end of the second-second housing 1232 and a second stopper ST2 disposed at the other end of the second-second housing 1232. The first stopper ST1 and the second stopper ST2 may be sequentially arranged along the optical axis direction.

[0409] In addition, a plurality of first stops ST1 may be provided and the plurality of first stops ST1 may be respectively provided on the moving path of the first lens assembly and the moving path of the second lens assembly. For convenience, the first stop ST1 will be described as a first-first stop ST1a and a first-second stop ST1b. Similarly, a plurality of second stops ST2 may be provided and the plurality of second stops ST2 may be respectively provided on the moving path of the first lens assembly and the moving path of the second lens assembly. In addition, the second stop ST2 will be described as a second-first stop ST2a and a second-second stop ST2b.

[0410] The first-first stopper ST1a and the second-first stopper ST2a may be positioned on a moving path of the first lens assembly. The first-second stopper ST1b and the second-second stopper ST2b may be positioned on a moving path of the second lens assembly.

[0411] The first-first stopper ST1a and the first-second stopper ST1b may overlap in the second direction. Alternatively, the first-first stopper ST1a and the first-second stopper ST1b may be misaligned in the second direction.

[0412] In addition, the second-first stopper ST2a and the second-second stopper ST2b may be positioned so as to be misaligned in the second direction. The distance between the first-first stopper ST1a and the second-first stopper ST2a in the third direction may be smaller than the distance between the first-second stopper ST1b and the second-second stopper ST2b. This is a configuration that reflects that the movable distance (stroke) of the first lens assembly is smaller than the movable distance (stroke) of the second lens assembly.

[0413] In an embodiment, the second yoke unit or yoke unit YK may be disposed at an outer side of the second driving unit, and for example, the yoke unit YK may be disposed at an outer side of the fourth coil and the fifth coil. The second yoke unit may include a first yoke YK1 and a second yoke YK2.

[0414] The first yoke YK1 and the second yoke YK2 may be disposed opposite to each other. For example, the first yoke YK1 and the second yoke YK2 may be positioned corresponding to each other with respect to the optical axis.

[0415] The first yoke YK1 can be positioned adjacent to the fourth coil 1251a. The second yoke YK2 can be positioned adjacent to the fifth coil 1251b. The fourth coil 1251a and the fifth coil 1251b can be positioned at the inner side of the first yoke YK1 and the second yoke YK2. In addition, the first yoke YK1, the fourth coil 1251a, the fifth coil 1251b and the second yoke YK2 can be arranged in sequence along a direction (e.g., the second direction). The first yoke YK1 can generate an attraction force with the fourth magnet. In addition, the second yoke YK2 can generate an attraction force with the fifth magnet. Therefore, the posture maintenance of the first lens assembly and the second lens assembly can be performed.

[0416] In addition, the thickness of the first yoke YK1 and the thickness of the second yoke YK2 can vary in some areas. With this configuration, the influence of the magnetic force generated by the fourth magnet and the fifth magnet or the fourth coil and the fifth coil on another magnet or coil can be suppressed. For example, the first yoke YK1 can suppress the magnetic force generated by the fourth magnet from being applied to the fifth magnet and the fifth coil.

[0417] Reference Figures 17a to 17f , in the second camera actuator according to the embodiment, the first sub-housing 1231 may include a fixed lens. In addition, as described above, the second sub-housing 1232 may be arranged to be parallel to the first sub-housing 1231 in the optical axis direction or the third direction (Z-axis direction). In this case, a lens assembly that moves in the optical axis direction may be arranged in the second sub-housing 1232, but a fixed lens that does not move in the optical axis direction may be arranged in the first sub-housing 1231. In addition, the first sub-housing 1231 and the second sub-housing 1232 may be connected by a connecting member BM provided between the first sub-housing 1231 and the second sub-housing 1232.

[0418] Specifically, the first sub-shell 1231 may include a retainer portion HP and a wing portion WP extending outwardly from the retainer portion HP. The wing portion WP may be arranged to surround a portion of the outer surface of the retainer portion HP. In addition, the retainer portion HP and the wing portion WP may have an integral structure or a separate structure. Hereinafter, the integral structure will be described.

[0419] In addition, the length of the holder portion HP in the first direction or the second direction may be smaller than the length of the wing portion WP in the first direction or the second direction.

[0420] In addition, the holder portion HP may include a first holder portion HP1 disposed above the wing portion WP and a second holder portion HP2 disposed below the wing portion WP. For example, the first holder portion HP1, the wing portion WP, and the second holder portion HP2 may be sequentially disposed along the optical axis direction.

[0421] The length LT1 of the first retainer part HP1 in the optical axis direction may be different from the length LT2 of the second retainer part HP2 in the optical axis direction. The length LT1 of the first retainer part HP1 in the optical axis direction may be smaller than the length LT2 of the second retainer part HP2 in the optical axis direction. With this configuration, the coupling strength between the first sub-housing 1231 and the second sub-housing can be increased, and active alignment can be easily performed to tilt the first sub-housing 1231. Therefore, the resolution of the camera module can be improved.

[0422] In addition, the second housing or the second camera actuator may further include a preventing member at least partially overlapping the second holder portion HP2 and the second sub housing. Figure 17q ) can be arranged in the second sub-housing 1232 (see Figure 17g ) on the outer surface and overlaps with the second retainer portion HP2 in the first direction. Figure 17q ) can overlap with the second sub-shell at least partially in the first direction (X-axis direction). With this configuration, even when the second holder portion HP2 and the second sub-shell are separated by a predetermined distance in the optical axis direction, foreign matter can be easily prevented from flowing into the first sub-shell or the second sub-shell. In addition, the preventing member TP (see Figure 17q ) can block light.

[0423] The wing portion WP may include one surface WPS1 and another surface WPS2. The one surface WPS1 and another surface WPS2 of the wing portion WP may be sequentially arranged along the optical axis direction and positioned to face each other. In addition, the other surface WPS2 may include stopper support portions WPR1 and WPR2 extending along the optical axis direction or a third direction (Z-axis direction). At least one stopper support may be formed.

[0424] In an embodiment, the stopper support portion may include a first stopper support portion WPR1 and a second stopper support portion WPR2. The first stopper support portion WPR1 and the second stopper support portion WPR2 may be spaced apart from each other along the second direction. The second holder portion HP2 may be positioned between the first stopper support portion WPR1 and the second stopper support portion WPR2. For example, the first stopper support portion WPR1 and the second stopper support portion WPR2 may be symmetrically arranged about the first sub-housing 1231 or the optical axis.

[0425] The first stopper support portion WPR1 and the second stopper support portion WPR2 may have different lengths in the optical axis direction. For example, the length HE1 of the first stopper support portion WPR1 in the optical axis direction may be greater than the length HE2 of the second stopper support portion WPR2 in the optical axis direction. For example, the length of the stopper support portion may be changed differently depending on the contact point with the first lens assembly or the second lens assembly. In an embodiment, the moving distance of the second lens assembly in the optical axis direction may be relatively long compared to the moving distance of the first lens assembly in the optical axis direction. Therefore, the length of the second stopper support portion WPR2 adjacent to the second lens assembly in the optical axis direction may be less than the length of the first stopper support portion WPR1 in the optical axis direction. Therefore, it can be easily ensured that the stroke or maximum moving distance of the second lens assembly is greater than the stroke or maximum moving distance of the first lens assembly.

[0426] In addition, the other surface WPS2 of the wing-shaped portion WP may face the second sub-housing. In addition, the other surface WPS2 of the wing-shaped portion WP may be spaced apart from the second sub-housing. In an embodiment, at least a portion of the other surface WPS2 of the wing-shaped portion WP may be spaced apart from the second sub-housing.

[0427] In addition, the first holder portion HP1 and the second holder portion HP2 may include a flat portion FLP and a rounded portion ROP. This may be a structure corresponding to the shape of the first lens group 1221a. For example, at least some lenses of the first lens group 1221a may be cut along a plane perpendicular to the first direction. Therefore, the first lens group 1221a may have flat surfaces facing each other or opposite to each other in the first direction. Correspondingly, the first holder portion HP1 and the second holder portion HP2 may also have a flat portion FLP. With this configuration, the optical path can be extended while minimizing the thickness of the camera module.

[0428] Furthermore, the length of the rounded portion ROP of the first holder part HP1 and the length of the rounded portion ROP of the second holder part HP2 may be different or the same. Likewise, the length of the flat portion FLP of the first holder part HP1 and the length of the flat portion FLP of the second holder part HP2 may be different or the same.

[0429] Furthermore, the first holder part HP1 or the second holder part HP2 may have a holder protrusion. Hereinafter, the second holder part HP2 will be described.

[0430] The second holder portion HP2 may include a holder protrusion HP2P disposed at an end portion of the second holder portion along the optical axis direction. The holder protrusion HP2P may be positioned on the rounded portion ROP. For example, the holder protrusion HP2P may be positioned on the rounded portion ROP of the second holder portion HP2. In addition, the holder portion HP or the second holder portion HP2 may have a maximum thickness TK1 at the rounded portion ROP that is greater than the maximum thickness TK2 at the flat portion FLP. With this configuration, the holder portion HP and the first sub-housing 1231 may have improved rigidity. That is, the second camera actuator may have improved durability.

[0431] In addition, the stopper support parts WPR1 and WPR2 may have a concave groove in the second direction (Y-axis direction) or the first direction. With this configuration, the first sub-housing may have a symmetrical structure. For example, the insertion of the first lens group may also be easily performed.

[0432] In addition, in the first sub-housing according to the embodiment, the alignment mark AM and the visual mark VM may be positioned on the wing-shaped portion. For example, the alignment mark AM and the visual mark VM may be positioned on the lower surface WPS2 of the wing-shaped portion in the first sub-housing.

[0433] In addition, in the first sub-housing 1231 according to the embodiment, the edge area of ​​the lower surface WPS2 of the wing-shaped portion WP may have a flat structure. In addition, the inner side of the edge area may be a recess or a groove. Therefore, the coupling member can be easily applied to the edge area. In addition, the movement of the coupling member to the first stoppers ST1a and ST1b positioned at the inner side of the edge area can be suppressed to the maximum extent.

[0434] In addition, the wing portion WP may have a groove Pih corresponding to the pin hole positioned in the edge region. Therefore, the shape of the first sub housing 1231 may be maximally suppressed from being deformed with respect to the optical axis.

[0435] In addition, the upper surface WPS1 of the wing portion WP in the first sub-housing 1231 may also have a flat or planar area. Therefore, the first sub-housing 1231 may be easily moved to the second sub-housing by suction.

[0436] In addition, the second sub-housing 1232 may include side portion grooves 1232cg and 1232dg in an area adjacent to the first sub-housing 1231. Therefore, even when the first sub-housing 1231 is tilted relative to the optical axis for active alignment, contact with the second sub-housing can be suppressed. Therefore, it is possible to easily ensure a movement radius for optical axis alignment, etc. and improve the reliability of the second camera actuator.

[0437] Reference Figure 17g , Figure 17h and Fig.17i As described above, the second housing 1230 (particularly, the second-second housing 1232) may include a first side portion 1232a and a second side portion 1232b. The first side portion 1232a and the second side portion 1232b may be positioned to correspond to each other. For example, the first side portion 1232a and the second side portion 1232b may be symmetrically arranged about a third direction. The second drive coil may be positioned on the first side portion 1232a and the second side portion 1232b. In addition, the second board unit may be seated on the outer surface of the first side portion 1232a and the outer surface of the second side portion 1232b. The second board unit may be positioned at the outside of the drive coil and electrically connected to the drive coil.

[0438] For example, the first plate may be positioned on an outer surface of the first side portion 1232a, and the second plate may be positioned on an outer surface of the second side portion 1232b.

[0439] In addition, the first guide grooves GG1a and GG1b in which the first spherical member and the second spherical member are seated may be positioned in the inner surface of the first side portion 1232a. The first guide grooves GG1a and GG1b may face the above-mentioned first recess and second recess. Similarly, the second guide grooves GG2a and GG2b in which the first spherical member and the second spherical member are seated may be positioned in the inner surface of the second side portion 1232b. The first guide grooves GG1a and GG1b may face the above-mentioned first recess and second recess.

[0440] In addition, the first side portion 1232a may include a first side portion hole 1232ah. The fourth magnet may be positioned in the first side portion hole 1232ah. In addition, the length of the first side portion hole 1232ah in the first direction may be smaller than the length of the first coil in the first direction.

[0441] In addition, the second side portion 1232b may include a second side portion hole 1232bh. The fifth magnet may be positioned in the second side portion hole 1232bh. In addition, the length of the second side portion hole 1232bh in the first direction may be smaller than the length of the fifth coil in the first direction.

[0442] In addition, the second-second housing 1232 may include a housing hole 1232h provided in one of the upper and lower portions of the second-second housing. The coupling can be easily performed through the housing hole 1232h, or the first lens assembly and the second lens assembly can be inspected (e.g., visually inspected).

[0443] In addition, the first guide grooves GG1a and GG1b positioned on the first side portion 1232a may extend in the third direction. In addition, the first guide grooves GG1a and GG1b may have different shapes. For example, any one of the first guide grooves GG1a may be an inclined groove, and the other guide groove GG1b may be a flat structure. This may also be applied to the second guide grooves GG2a and GG2b in the same manner. The first spherical member and the second spherical member may be seated in the inclined groove and the flat structure so that the first lens assembly or the second lens assembly may move in the optical axis direction.

[0444] Further references Figure 17i to Figure 17o , the second housing 1230 may include a first side portion 1232a, a second side portion 1232b, a third side portion 1232c, a fourth side portion 1232d, a fifth side portion 1232e, and a sixth side portion 1232f.

[0445] As described above, the first side portion 1232a and the second side portion 1232b may be symmetrically arranged about the third direction or the optical axis direction. In addition, the first side portion 1232a and the second side portion 1232b may be positioned to correspond to or face each other in the horizontal direction or the second direction (Y-axis direction).

[0446] The third side portion 1232c and the fourth side portion 1232d may be positioned to correspond to or face each other in the vertical direction or the first direction (X-axis direction). The third side portion 1232c may be a side portion of the second housing 1232 having a flat surface, and the fourth side portion 1232d may be a side portion of the second housing 1232 having a bottom surface.

[0447] In addition, the fifth side portion 1232e and the sixth side portion 1232f may be positioned to correspond to or face each other in the optical axis direction or the third direction (Z-axis direction). Therefore, the fifth side portion 1232e may be a side portion of the second housing 1232 positioned adjacent to the first camera actuator. In addition, the sixth side portion 1232f may be a side portion of the second housing 1232 positioned adjacent to the base or the image sensor.

[0448] In addition, the hole provided at the outer side of the fifth side portion 1232e may be a structure of a protrusion and a groove for coupling with the first actuator.

[0449] The guide grooves GG1 a , GG1 b , GG2 a , and GG2 b may be positioned on an inner surface of the second case 1230 .

[0450] The guide groove may include first guide grooves GG1a and GG1b and second guide grooves GG2a and GG2b. As described above, the first spherical member and the second spherical member may be positioned in the guide groove. That is, the first spherical member and the second spherical member may be positioned between the guide groove and the lens assembly (the first lens assembly and the second lens assembly).

[0451] In addition, outer grooves 1232ag1, 1232ag2, 1232bg1, and 1232bg2 corresponding to the guide grooves GG1a, GG1b, GG2a, and GG2b may be provided on an outer surface of the second housing 1230. That is, the second housing 1230 may include outer grooves 1232ag1, 1232ag2, 1232bg1, and 1232bg2 positioned on an outer surface of the second housing.

[0452] The guide grooves GG1 a , GG1 b , GG2 a , and GG2 b may be positioned on inner surfaces of side portions (first and second side portions) of the second housing 1230 .

[0453] The outer grooves 1232ag1 , 1232ag2 , 1232bg1 , and 1232bg2 may be positioned on outer surfaces of side portions (first side portions and second side portions) of the second housing 1230 .

[0454] In addition, in an embodiment, the guide grooves GG1a, GG1b, GG2a, and GG2b may overlap with the outer grooves 1232ag1, 1232ag2, 1232bg1, and 1232bg2 in the horizontal direction or the second direction (Y-axis direction). For example, the guide grooves GG1a, GG1b, GG2a, and GG2b may overlap with the outer grooves 1232ag1, 1232ag2, 1232bg1, and 1232bg2 in the horizontal direction or the second direction (Y-axis direction) at least partially.

[0455] Therefore, the flatness of the guide groove can be maintained according to the injection of the second shell. Therefore, the first lens assembly and the second lens assembly can be moved along the guide groove along the optical axis through the spherical member (the first spherical member and the second spherical member). That is, since the flatness or flatness of the guide groove is maintained, the occurrence of eccentricity or tilt of the lens of the first lens assembly and the lens of the second lens assembly can be minimized. Therefore, the second camera actuator according to the embodiment can provide optimal optical characteristics.

[0456] In addition, the second housing 1230 may include the side partial holes 1232ah and 1232bh as described above. As described above, the first side portion 1232a may include the first side partial hole 1232ah. In addition, the second side portion 1232b may include the second side partial hole 1232bh. In addition, the fourth magnet may be positioned in the first side partial hole 1232ah. The fifth magnet may be positioned in the second side partial hole 1232bh.

[0457] In addition, the guide grooves GG1a, GG1b, GG2a, and GG2b according to the embodiment may be disposed above or below the side partial holes 1232ah and 1232bh.

[0458] In addition, the outer grooves 1232ag1 , 1232ag2 , 1232bg1 , and 1232bg2 may be disposed above or below the side partial holes 1232ah and 1232bh .

[0459] In an embodiment, as described above, the guide groove may include first guide grooves GG1a and GG1b and second guide grooves GG2a and GG2b facing each other in the optical axis direction. In addition, the side partial hole may include a first side partial hole 1232ah and a second side partial hole 1232bh facing each other in the optical axis direction. In addition, the outer groove may include first outer grooves 1232ag1 and 1232ag2 and second outer grooves 1232bg1 and 1232bg2 facing each other in the optical axis direction. The first outer grooves 1232ag1 and 1232ag2 and the second outer grooves 1232bg1 and 1232bg2 may be symmetrical to each other about the optical axis. Therefore, the flatness described below may be further improved.

[0460] In addition, the first guide groove may include a first-first guide groove GG1a disposed above the first side partial hole 1232ah and a first-second guide groove GG1b disposed below the first side partial hole 1232ah.

[0461] The second guide groove may include a second-second guide groove GG2a disposed above the second side partial hole 1232bh and a second-second guide groove GG2b disposed below the second side partial hole 1232bh.

[0462] The first-first guide groove GG1a may overlap the first-second guide groove GG1b in the first direction or the vertical direction. In addition, the second-first guide groove GG2a may overlap the second-first guide groove GG2b in the first direction or the vertical direction.

[0463] In addition, the first outer groove may include a first-first outer groove 1232ag1 disposed above the first side partial hole 1232ah and a first-second outer groove 1232ag2 disposed below the first side partial hole 1232ah.

[0464] The second outer groove may include a second-first outer groove 1232bg1 disposed above the second side partial hole 1232bh and a second-second outer groove 1232bg2 disposed below the second side partial hole 1232bh.

[0465] The first-first outer groove 1232ag1 may overlap the first-second outer groove 1232ag2 in the first direction or the vertical direction. In addition, the second-first outer groove 1232bg1 may overlap the second-second outer groove 1232bg2 in the first direction or the vertical direction.

[0466] In an embodiment, the first-first guide groove GG1a may overlap with the first-first outer groove 1232ag1 in the horizontal direction. In addition, the first-second guide groove GG1b may overlap with the first-second outer groove 1232ag2 in the horizontal direction. Therefore, the flatness of both the first-first guide groove GG1a and the first-second guide groove GG1b in which the first spherical member and the second spherical member are positioned can be improved.

[0467] In addition, the second-first guide groove GG2a may overlap with the second-first outer groove 1232bg1 in the horizontal direction. In addition, the second-second guide groove GG2b may overlap with the second-second outer groove 1232bg2 in the horizontal direction. Therefore, the flatness of both the second-first guide groove GG2a and the second-second guide groove GG2b in which the first spherical member and the second spherical member are positioned can be improved.

[0468] In addition, the first-first guide groove GG1a, the first-first outer groove 1232ag1, the second-first guide groove GG2a, and the second-first outer groove 1232bg1 can overlap each other in the horizontal direction or the second direction (Y-axis direction). In addition, the first-second guide groove GG1b, the first-second outer groove 1232ag2, the second-second guide groove GG2b, and the second-second outer groove 1232bg2 can overlap each other in the horizontal direction or the second direction (Y-axis direction). With this configuration, the flatness of both the first guide groove and the second guide groove can be improved. That is, the phenomenon that the first guide groove is misaligned with respect to one side or the second guide groove is misaligned with respect to one side can be suppressed.

[0469] In addition, as described above, the first-first guide groove GG1a and the first-second guide groove GG1b may have different shapes. For example, the first-first guide groove GG1a may be formed into a structure having an inclined groove, and the first-second guide groove GG1b may be formed into a structure having a flat surface. In addition, the second-first guide groove GG2a may be formed into a structure having a flat surface, and the second-second guide groove GG2b may be formed into a structure having an inclined groove. Therefore, the first-first guide groove GG1a may have a shape corresponding to the shape of the second-second guide groove GG2b. In addition, the first-second guide groove GG1b may have a shape corresponding to the shape of the second-first guide groove GG2a. As described above, the first guide groove and the second guide groove may have corresponding shapes alternately relative to the optical axis. Therefore, the assemblability of the first lens assembly and the second lens assembly seated in the first guide groove and the second guide groove by the spherical piece can be improved.

[0470] In addition, the side partial holes 1232ah and 1232bh can partially overlap with the outer grooves 1232ag1, 1232ag2, 1232bg1 and 1232bg2 in the horizontal direction or the second direction (Y-axis direction). With this configuration, the area or volume for improving the flatness of the guide groove in the second housing can be optimized.

[0471] In addition, the side partial holes 1232ah and 1232bh may not overlap with the guide grooves GG1a, GG1b, GG2a, and GG2b in the horizontal direction or the second direction (Y-axis direction). Therefore, the separation of the spherical members (first spherical member and second spherical member) disposed in the guide grooves GG1a, GG1b, GG2a, and GG2b can be prevented. In addition, the influence on the rolling motion of the spherical members can be minimized.

[0472] In addition, as described above, the guide grooves GG1a, GG1b, GG2a, and GG2b and the outer grooves 1232ag1, 1232ag2, 1232bg1, and 1232bg2 may be positioned above or below the side partial holes 1232ah and 1232bh to ensure a separation distance from the fourth and fifth magnets positioned in the side partial holes 1232ah and 1232bh. That is, the influence of the fourth and fifth magnets may be minimized.

[0473] In addition, the outer grooves 1232ag1, 1232ag2, 1232bg1 and 1232bg2 may have an inclined surface toward the side portion holes 1232ah and 1232bh. For example, the outer grooves 1232ag1, 1232aga2, 1232bg1 and 1232bg2 may have an inclined surface toward the inner side of the side portion holes 1232ah and 1232bh. Alternatively, the outer grooves 1232ag1, 1232ag2, 1232bg1 and 1232bg2 may have an inclined surface toward the center of the first side portion (or the second side portion). With this configuration, the highly improved flatness of the guide groove can be maintained.

[0474] The outer grooves 1232ag1 , 1232ag2 , 1232bg1 , and 1232bg2 may have the same length or different lengths in the vertical direction (X-axis direction) in the optical axis direction or the third direction (Z-axis direction).

[0475] For example, the length of the first-second outer groove 1232ag2 and the length of the second-second outer groove 1232bg2 may decrease along the optical axis direction. For example, the length of the first-second outer groove 1232ag2 and the second-second outer groove 1232bg2 in the vertical direction in the region adjacent to the first actuator may be greater than the length of the first-second outer groove 1232ag2 and the second-second outer groove 1232bg2 in the vertical direction in the region adjacent to the image sensor.

[0476] In addition, the second housing may include housing protrusions 1232pr1 and 1232pr2 protruding inwardly in the optical axis direction or the third direction (Z-axis direction).

[0477] The housing protrusion may include a first housing protrusion 1232pr1 and a second housing protrusion 1232pr2. The first housing protrusion 1232pr1 may be positioned on the inner surface of the third side portion 1232c. For example, the first housing protrusion 1232pr1 may protrude (or extend) from the inner surface of the third side portion 1232c toward the fourth side portion 1232d or toward the first lens assembly and the second lens assembly.

[0478] In addition, the second housing protrusion 1232pr2 can be positioned on the inner surface of the fourth side portion 1232d. For example, the second housing protrusion 1232 can protrude (or extend) from the inner surface of the fourth side portion 1232d toward the third side portion 1232c or toward the first lens assembly and the second lens assembly.

[0479] The housing protrusion can be positioned at the inner side of the first guide groove and the inner side of the second guide groove. That is, the housing protrusion can be positioned closer to the guide groove than the outer groove.

[0480] With this structure, changes in the shapes of the guide grooves GG1a, GG1b, GG2a, and GG2b of the second housing can be reduced. That is, the flatness of adjacent guide grooves can be maintained by increasing rigidity through the housing protrusion, etc. Therefore, the second camera actuator can provide a more improved straightness for the moving lens assembly. In addition, as described above, the second camera actuator can minimize the occurrence of decentering or tilting and provide optimal optical characteristics.

[0481] The housing protrusions 1232pr1 and 1232pr2 may be positioned between the first guide groove and the second guide groove. Specifically, the first housing protrusion 1232pr1 may be positioned between the first-first guide groove and the second-first guide groove. The second housing protrusion 1232pr2 may be positioned between the first-second guide groove and the second-second guide groove.

[0482] In addition, the first housing protrusion 1232pr1 may overlap the first-first guide groove and the second-first guide groove in the horizontal direction. In addition, the second housing protrusion 1232pr2 may overlap the first-second guide groove and the second-second guide groove in the horizontal direction.

[0483] In addition, the third side portion 1232c and the fourth side portion 1232d may include a side portion groove in an area adjacent to the first actuator. The side portion groove may be provided on each of the third side portion and the fourth side portion. In addition, the side portion grooves may overlap each other in the vertical direction. The third side portion and the fourth side portion may be easily coupled to the second-first housing as a fixed lens assembly by the side portion grooves. In addition, the size of the first lens group in the second-first housing may be ensured. That is, D-shaped cutting, etc. may not be applied to at least some lenses of the first lens group. Therefore, bright light (fno low) may be provided to the image sensor.

[0484] In addition, the second housing 1230 may include a gate groove 1232fh provided on an outer surface facing the side portions (the fifth side portion and the sixth side portion) in the optical axis direction or the third direction (Z-axis direction).

[0485] In an embodiment, the sixth side portion 1232f may include a gate groove 1232fh disposed on an outer surface of the sixth side portion. At least one gate groove 1232fh may be formed. In an embodiment, a plurality of gate grooves 1232fh may be formed. In addition, the gate groove 1232fh may be positioned at an edge of the outer surface of the sixth side portion 1232f.

[0486] For example, the gate groove 1232fh may be positioned to overlap with a lens such as glass in the horizontal direction or the second direction (Y-axis direction).

[0487] In addition, the gate groove 1232fh may overlap with the outer grooves 1232ag1, 1232ag2, 1232bg1, and 1232bg2 in the optical axis direction or the third direction (Z-axis direction). The gate groove 1232fh may be arranged to be misaligned with the guide grooves GG1a, GG1b, GG2a, and GG2b in the optical axis direction or the third direction (Z-axis direction). Alternatively, the gate groove 1232fh may not overlap with the guide grooves GG1a, GG1b, GG2a, and GG2b in the optical axis direction or the third direction (Z-axis direction).

[0488] With this configuration, when an injection solution (eg, resin) is injected into the gate groove 1232fh, changes in the shapes of the guide grooves GG1a, GG1b, GG2a, and GG2b may be minimized according to the flow of the solution.

[0489] In addition, the gate groove 1232fh can be arranged to be spaced apart from the guide grooves GG1a, GG1b, GG2a and GG2b in the horizontal direction or the second direction (Y-axis direction). In addition, the gate groove 1232fh can be positioned at the outer side of the guide grooves GG1a, GG1b, GG2a and GG2b. With this configuration, the injection molding solution can be injected without affecting the guide grooves as much as possible.

[0490] Reference Figure 17p , the first-first stopper ST1a and the second-first stopper ST2a in the second camera actuator may overlap in the optical axis direction or the third direction (Z-axis direction). In addition, a portion of the first lens assembly 1222a may move along the optical axis direction between the first-first stopper ST1a and the second-first stopper ST2a. That is, the maximum moving distance of the first lens assembly may be the first distance DS1 between the first-first stopper ST1a and the second-first stopper ST2a.

[0491] Likewise, the first-second stopper ST1b and the second-second stopper ST2b may overlap each other in the optical axis direction or the third direction (Z-axis direction). In addition, a portion of the second lens assembly 1222b may move along the optical axis direction between the first-second stopper ST1b and the second-second stopper ST2b. That is, the maximum moving distance of the second lens assembly may be the second distance DS2 between the first-second stopper ST1b and the second-second stopper ST2b.

[0492] In this case, the first distance DS1 and the second distance DS2 may be different or the same. In an embodiment, the first distance DS1 may be different from the second distance DS2. In an embodiment, the first distance DS1 may be smaller than the second distance DS2.

[0493] The ratio of the first distance DS1 to the second distance DS2 may be in the range of 1:1.5 to 1:4. That is, the moving distance of the first lens assembly 1222a may be smaller than the moving distance of the second lens assembly 1222b. In addition, the ratio of the moving distance of the first lens assembly to the moving distance of the second lens assembly may be in the range of 1:1.5 to 1:4.

[0494] In addition, since the first lens assembly moves as described above, the camera actuator can perform zooming. In addition, since the second lens assembly moves, the camera actuator can perform AF. Reflecting this, the moving distance for zooming can be smaller than the moving distance (or stroke) for AF.

[0495] In addition, for the difference in moving distance or stroke, the first-first stopper ST1a and the first-second stopper ST1b can be set to be at least partially misaligned in the second direction or the horizontal direction. Therefore, the first-first stopper ST1a and the first-second stopper ST1b can have a separation distance gd1 in the third direction.

[0496] In addition, the second-first stopper ST2a and the second-second stopper ST2b may be disposed to be at least partially misaligned in the second direction or the horizontal direction. Therefore, the second-first stopper ST2a and the second-second stopper ST2b may have a separation distance gd2 in the third direction.

[0497] Reference Figure 17q, in the second camera actuator according to the embodiment, the first sub-housing 1231 may be seated at the front end of the second sub-housing 1232. In this case, as described above, the coupling member BM may be positioned on one surface of the second sub-housing 1232. In addition, all the first lens assembly and the second lens assembly and the driving unit may be mounted in the second sub-housing 1232. In addition, as illustrated, the second board unit may be mounted on the side surface of the second sub-housing 1232. In this state, the first sub-housing 1231 may be seated on the upper surface of the second sub-housing 1232. In addition, active alignment (e.g., optical axis alignment) may be performed by tilting or moving the first sub-housing 1231 relative to the optical axis. Thereafter, curing may be performed on the coupling member. For example, the coupling member may be made of a resin such as epoxy resin. In addition, the above-mentioned curing may be performed when a predetermined amount of heat is applied. Thereafter, the circuit board may be mounted on the rear end of the second sub-housing 1232. Thereafter, the first camera actuator may be mounted at the front end of the second camera actuator and coupled to the second camera actuator. In addition, electrical connection with the first camera actuator and the second camera actuator may be performed by bending a plate of the circuit board. In addition, in any of the above-described assembling operations, the preventing member TP may be provided on the side surface of the second sub housing 1232 .

[0498] More specifically, refer to Figure 17r to Figure 17t , in the second camera actuator according to the embodiment, the first sub housing 1231 may be positioned on an outer surface of the fifth side portion 1232 e of the second sub housing 1232 .

[0499] In addition, the connecting member BM can be positioned on the outer surface of the fifth side portion 1232e of the second sub-housing 1232. That is, the connecting member BM can be applied to the outer surface of the fifth side portion 1232e. The connecting member BM can be positioned at the edge of the outer surface of the fifth side portion 1232e. In addition, the connecting groove 1232eg can be positioned at the outermost part of the fifth side portion 1232e. As described above, the connecting groove 1232eg can be positioned to correspond to the protrusion of the first camera actuator. Therefore, the protrusion of the first camera actuator can be accommodated in the connecting groove 1232eg. In addition, the first camera actuator and the second camera actuator can be connected.

[0500] In addition, the coupling member BM may be positioned at the inner side of the coupling groove 1232eg. Therefore, active alignment by the first sub-housing 1231 may be performed before assembly or coupling between the first camera actuator and the second camera actuator. That is, assemblability may be improved and optical performance may be improved.

[0501] In addition, the coupling member BM may be positioned at the outer side of the first stoppers ST1a and ST1b. In addition, the coupling member BM may be positioned at the outer side of the stopper support portions WPR1 and WPR2.

[0502] In addition, the first sub-housing 1231 and the second sub-housing 1232 can be arranged to be spaced a predetermined distance from each other by a coupling member for active alignment. That is, for example, by providing a coupling member BM between the first sub-housing 1231 and the second sub-housing 1232, a separation space can exist between the first sub-housing 1231 and the second sub-housing 1232.

[0503] The second camera actuator may be divided into one area Se1 and another area Se2 with respect to the optical axis OX In this case, the distances between the first sub-housing 1231 and the second sub-housing 1232 in the one area Se1 and another area Se2 may be the same or different.

[0504] In this example, the optical axis OX of the second camera actuator may be parallel to the third direction and parallel to the second sub housing. In this case, the central axis AX of the first sub housing 1231 may correspond to the optical axis OX.

[0505] In this example, a first separation distance gap1 in the optical axis direction in one region Se1 between the wing-shaped portion WP and the second sub-housing 1232 and a second separation distance gap2 in the optical axis direction in another region Se2 between the wing-shaped portion WP and the second sub-housing 1232 may be the same. In addition, a third separation distance gap3 in the optical axis direction between the retainer portion or the second retainer portion and the second sub-housing 1232 may also be the same in one region and another region.

[0506] Reference Figure 17u and Figure 17x In the second camera actuator according to various examples, the central axis AX of the first sub housing 1231 may be inclined at a predetermined angle θ-b, θ-c, θ-d, or θ-e relative to the optical axis OX. In an embodiment, the central axis AX may be a vertical axis that bisects a surface perpendicular to the center of gravity of the first sub housing or perpendicular to the optical axis.

[0507] In addition, as described above, in the second camera actuator, the separation space can be divided into one area Se1 and another area Se2 relative to the optical axis OX. In this case, the distance between the first sub-housing 1231 and the second sub-housing 1232 in one area Se1 and another area Se2 may be the same or different.

[0508] In this example, the optical axis OX of the second camera actuator may be parallel to the third direction and parallel to the second sub housing. In this case, the central axis AX of the first sub housing 1231 may correspond to the optical axis OX.

[0509] In this example, a first separation distance gap1 in the optical axis direction in one region Se1 between the wing-shaped portion WP and the second sub-housing 1232 and a second separation distance gap2 in the optical axis direction in another region Se2 between the wing-shaped portion WP and the second sub-housing 1232 may be different. That is, the first separation distance gap1 and the second separation distance gap2 may be different. In addition, the third separation distance gap3 may also vary in a region other than the optical axis OX.

[0510] In addition, in this example, the predetermined angles θ-b, θ-c, θ-d, and θ-e may not be right angles. That is, one surface of the first sub-housing 1231 may not be perpendicular to the optical axis OX. In addition, the center axis AX of the first sub-housing 1231 may not be parallel to the optical axis OX. That is, the center axis AX of the first sub-housing 1231 may not be parallel to the optical axis OX. Alternatively, the center axis AX of the first sub-housing 1231 may not be aligned with the center axis of the second sub-housing 1232 or may not be parallel to the center axis of the second sub-housing 1232. In addition, in the specification, the center axis of the second sub-housing 1232 corresponding to the optical axis will be described.

[0511] In addition, the parts of the coupling member BM that are separated to the maximum in one direction may have different thicknesses. For example, some areas of the coupling member BM and the remaining areas may have different thicknesses on the XY plane. In addition, in the coupling member BM, the thickness in some areas of the edge and the thickness in the remaining areas of the edge may be different in one direction on the XY plane.

[0512] For example, the thickness of the coupling member BM may vary along the second direction on the XY plane. Alternatively, the thickness of the coupling member BM may vary along the first direction on the XY plane. According to the active alignment, the second camera actuator may have the above-described configuration.

[0513] In addition, the second sub-housing 1232 may include side partial grooves 1232cg and 1232dg in an area adjacent to the first sub-housing 1231. In this case, even when the first sub-housing 1231 is tilted for optical axis alignment, the first sub-housing 1232 may not contact the second sub-housing. That is, the side partial groove 1232cg and the first sub-housing 1231 may be spaced a predetermined distance from each other. Therefore, it is possible to easily ensure a movement radius for optical axis alignment, etc. and improve the reliability of the second camera actuator.

[0514] In addition, the first stoppers ST1a and ST1b connected to the first sub-housing 1231 may be inclined at a predetermined angle with respect to the XY plane. The structure or position of the first stoppers may be determined by the movement or inclination of the first sub-housing 1231.

[0515] In addition, the distance between the first stoppers ST1a and ST1b and the second stopper in the optical axis direction may be different corresponding to the area of ​​the first stoppers ST1a and ST1b. This may be derived from the inclined structure of the first sub-housing 1231 through the first stoppers ST1a and ST1b.

[0516] In the modified example, when the first sub-housing 1231 is tilted for optical axis alignment, the first sub-housing 1231 may contact the second sub-housing in some areas. Therefore, when the optical axis is aligned, the tilt or movement radius of the first sub-housing 1231 may be limited. With this configuration, the assemblability and reliability of the second camera actuator may be improved.

[0517] That is, the fourth separation distance gap4 - the separation distance between the first sub-shell and the second sub-shell in the first direction (X-axis direction) - can also vary in areas other than the optical axis OX. For example, the fourth separation distance gap4 in one area can be different from the fourth separation distance gap4 in another area.

[0518] Reference Fig.18 and Fig.19 In the camera module according to the embodiment, by generating an electromagnetic force DEM1 between the fourth magnet 1252a and the fourth coil 1251a, the first lens assembly 1222a can be moved along a track positioned on the inner surface of the shell through the first spherical part B1 and the second spherical part B2 in a direction parallel to the optical axis, that is, along a third direction (Z-axis direction) or in a direction opposite to the third direction.

[0519] Specifically, in the camera module according to the embodiment, the fourth magnet 1252a may be provided in the first lens assembly 1222a, for example, by a vertical monopole magnetization method. For example, in the embodiment, both the N pole and the S pole of the fourth magnet 1252a may be positioned to face the fourth coil 1251a. Therefore, each of the N pole and the S pole of the fourth magnet 1252a may be provided to correspond to a region where a current flows from the fourth coil 1251a in the X-axis direction or in a direction opposite to the X-axis direction.

[0520] In an embodiment, when a magnetic force is applied from the N pole of the fourth magnet 1252a in a direction opposite to the second direction (Y-axis direction) and a current DE1 flows in the fourth coil 1251a corresponding to the N pole in a direction opposite to the first direction (X-axis direction), the electromagnetic force DEM1 may act in a third direction (Z-axis direction) according to the interaction between the electromagnetic force and the magnetic force (e.g., Fleming's left-hand rule).

[0521] In addition, in an embodiment, when a magnetic force is applied from the S pole of the fourth magnet 1252a along the second direction (Y-axis direction) and the current DE1 flows in the fourth coil 1251a corresponding to the S pole along the first direction (X-axis direction), the electromagnetic force DEM1 can act along the Z-axis direction according to the interaction between the electromagnetic force and the magnetic force.

[0522] At this time, since the fourth coil 1251a is in a state of being fixed to the side portion of the second housing, the first lens assembly 1222a on which the fourth magnet 1252a is disposed can move in a direction opposite to the Z-axis direction by the electromagnetic force DEM1 according to the current direction. That is, the second driving magnet can move in a direction opposite to the electromagnetic force applied to the second driving coil. In addition, the direction of the electromagnetic force can change according to the current of the coil and the magnetic force of the magnet.

[0523] Therefore, the first lens assembly 1222a can be moved in a third direction or a direction parallel to the optical axis direction (in both directions) along the track positioned on the inner surface of the housing by the first spherical member B1 and the second spherical member B2. At this time, the electromagnetic force DEM1 can be controlled to be proportional to the current DE1 applied to the fourth coil 1251a.

[0524] The first lens assembly 1222a or the second lens assembly 1222b may include a first recess RS1 in which the first spherical member B1 is seated. In addition, the first lens assembly 1222a or the second lens assembly 1222b may include a second recess RS2 in which the second spherical member B2 is seated. The length of the first recess RS1 may be preset in the optical axis direction (Z-axis direction). In addition, the length of the second recess RS2 may be preset in the optical axis direction (Z-axis direction). Therefore, the moving distance of the first spherical member B1 and the second spherical member B2 may be adjusted in the optical axis direction in each recess. That is, the first recess RS1 or the second recess RS2 may be a stopper for the first spherical member B1 and the second spherical member B2.

[0525] In addition, in the camera module according to the embodiment, the fifth magnet 1252b can be provided on the second lens assembly 1222b by, for example, a vertical monopole magnetization method. For example, in the embodiment, both the N pole and the S pole of the fifth magnet 1252b can be positioned to face the fifth coil 1251b. Therefore, each of the N pole and the S pole of the fifth magnet 1252b can be provided to correspond to the region where the current flows from the fifth coil 1251b in the X-axis direction or in the direction opposite to the X-axis direction.

[0526] In an embodiment, when a magnetic force DM2 is applied from the N pole of the fifth magnet 1252b along a second direction (Y-axis direction) and a current DE2 flows in the fifth coil 1251b corresponding to the N pole along a first direction (X-axis direction), the electromagnetic force DEM2 may act along a third direction (Z-axis direction) according to the interaction between the electromagnetic force and the magnetic force (e.g., Fleming's left-hand rule).

[0527] In addition, in an embodiment, when a magnetic force is applied from the S pole of the fifth magnet 1252b in a direction opposite to the second direction (Y-axis direction) and the current DE2 flows in the fifth coil 1251b corresponding to the S pole in a direction opposite to the first direction (X-axis direction), the electromagnetic force DEM2 can act along the Z-axis direction according to the interaction between the electromagnetic force and the magnetic force.

[0528] At this time, since the fifth coil 1251b is in a state of being fixed to the side portion of the second shell, the second lens assembly 1222b on which the fifth magnet 1252b is disposed can be moved in a direction opposite to the Z-axis direction by the electromagnetic force DEM2 according to the direction of the current. For example, as described above, the direction of the electromagnetic force can be changed according to the current of the coil and the magnetic force of the magnet. Therefore, the second lens assembly 1222b can be moved in a direction parallel to the third direction (Z-axis direction) along the track located on the inner surface of the second shell through the second spherical piece B2. At this time, the electromagnetic force DEM2 can be controlled to be proportional to the current DE2 applied to the fifth coil 1251b.

[0529] Reference Fig. 20 In the camera module according to the embodiment, the second driving unit may provide driving forces F3A, F3B, F4A, and F4B that move the first lens assembly 1222a and the second lens assembly 1222b of the lens unit 1220 in a third direction (Z-axis direction). As described above, the second driving unit may include a second driving coil 1251 and a second driving magnet 1252. In addition, the lens unit 1220 may be moved in the third direction (Z-axis direction) by an electromagnetic force generated between the second driving coil 1251 and the second driving magnet 1252.

[0530] At this time, the fourth coil 1251a and the fifth coil 1251b may be disposed in holes formed in the side portions (e.g., the first side portion and the second side portion) of the second housing 1230. In addition, the fifth coil 1251b may be electrically connected to the first board 1271. The fourth coil 1251a may be electrically connected to the second board 1272. Therefore, the fourth coil 1251a and the fifth coil 1251b may receive a driving signal (e.g., current) from a driving driver on the circuit board 1300 through the second board unit 1270.

[0531] At this time, the first lens assembly 1222a on which the fourth magnet 1252a is seated can be moved along the third direction (Z-axis direction) by the electromagnetic forces F3A and F3B between the fourth coil 1251a and the fourth magnet 1252a. In addition, the second lens group 1221b seated on the first lens assembly 1222a can also be moved along the third direction.

[0532] In addition, the second lens assembly 1222b on which the fifth magnet 1252b is seated can be moved along the third direction (Z-axis direction) by the electromagnetic forces F4A and F4B between the fifth coil 1251b and the fifth magnet 1252b. In addition, the third lens group 1221c seated on the second lens assembly 1222b can also be moved along the third direction.

[0533] Therefore, as described above, the focal length or magnification of the optical system can be changed by moving the second lens group 1221b and the third lens group 1221c. In an embodiment, the magnification can be changed by moving the second lens group 1221b. That is, zooming can be performed. In addition, the focus can be adjusted by moving the third lens group 1221c. That is, autofocus can be performed. With this configuration, the second camera actuator can be fixed zoom or continuous zoom.

[0534] Fig.21 is a schematic diagram illustrating a circuit board according to an embodiment.

[0535] Reference Fig.21 As described above, the circuit board 1300 according to the embodiment may include a first circuit board unit 1310 and a second circuit board unit 1320. The first circuit board unit 1310 may be positioned below the base and coupled to the base. In addition, the image sensor IS may be disposed on the first circuit board unit 1310.

That is, the base may be positioned at the rear end of the second camera actuator, and the image sensor and the circuit board (first circuit board unit) may be positioned at the rear end of the base. The base may include a filter (e.g., an infrared filter).

[0536] In addition, the second circuit board unit 1320 can be positioned on the side portion of the base. In particular, the second circuit board unit 1320 can be positioned on the first side portion of the base. Therefore, the second circuit board unit 1320 can be positioned adjacent to the fourth coil, which is positioned adjacent to the first side portion for simple electrical connection. In addition, the second circuit board unit 1320 can be positioned on the second side portion of the base. As described above, a plurality of second circuit board units 1320 can be formed. However, the present disclosure is not limited thereto, and the second circuit board unit 1320 can be only arranged on any one of the first side portion and the second side portion.

[0537] In addition, the circuit board 1300 may further include a fixing plate (not shown) positioned on a side surface of the circuit board. Therefore, even when the circuit board 1300 is made of a flexible material, the circuit board 1300 may be coupled to the base while maintaining rigidity through the fixing plate.

[0538] The second circuit board unit 1320 of the circuit board 1300 may be positioned on a side portion of the second drive unit 1250. The circuit board 1300 may be electrically connected to the first drive unit and the second drive unit. For example, the electrical connection may be made by surface mounting technology (SMT). However, the present disclosure is not limited to this method.

[0539] The circuit board 1300 may include a circuit board having a wiring pattern that can be electrically connected, such as a rigid printed circuit board (rigid PCB), a flexible PCB, and a rigid-flexible PCB. However, the present disclosure is not limited to these types.

[0540] In addition, the circuit board 1300 may be electrically connected to another camera module in the terminal or a processor of the terminal. Therefore, the camera actuator and the camera module including the camera actuator may transmit and receive various signals within the terminal.

[0542] Reference Fig. 22 , the first lens assembly 1222a and the second lens assembly 1222b can be arranged to be spaced apart from each other in the optical axis direction (Z axis direction). In addition, the first lens assembly 1222a and the second lens assembly 1222b can be moved along the optical axis direction (Z axis direction) by the second driving unit. For example, an auto focus or zoom function can be performed by moving the first lens assembly 1222a and the second lens assembly 1222b.

[0543] In addition, the first lens assembly 1222a may include a first lens holder LAH1 for holding and coupling the second lens group 1221b. The first lens holder LAH1 may be coupled to the second lens group 1221b. In addition, the first lens holder LAH1 may include a first lens hole LH1 for accommodating the second lens group 1221b. That is, the second lens group 1221b including at least one lens may be disposed in the first lens hole LH1. The first lens holder LAH1 is the same as a housing unit (e.g., a first housing unit or a second housing unit) to be described below and may be used interchangeably with the housing unit.

The first outer surface MM1 may be the lower surface of the first lens holder LAH1 in the optical axis direction (Z-axis direction). In addition, the third outer surface MM3 to be described below may be the upper surface of the first lens holder LAH1. In addition, the second outer surface MM2 may be the upper surface of the second lens holder LAH2, and the fourth outer surface MM4 may be the lower surface of the second lens holder LAH2.

[0547] For example, a coupling member (not shown) may be in contact with at least one of the first outer surface MM1 and the second outer surface MM2.

[0548] Fig.23 is a perspective view of a mobile terminal to which a camera module according to an embodiment is applied.

[0549] like Fig.23 As illustrated in FIG. 1 , the mobile terminal 1500 according to the embodiment may include a camera module 1000 , a flash module 1530 , and an AF device 1510 disposed on a rear surface thereof.

[0550] The camera module 1000 may include an image capturing function and an AF function. For example, the camera module 1000 may include an AF function using an image.

[0551] The camera module 1000 processes image frames of a still image or a moving image obtained by an image sensor in a capture mode or a video call mode.

[0560] Reference Fig.24 The vehicle 700 in the embodiment may include wheels 13FL and 13FR that rotate by a power source and a predetermined sensor. The sensor may be a camera sensor 2000, but the present disclosure is not limited thereto.

[0561] The camera sensor 2000 may be a camera sensor applied to the camera module 1000 according to the embodiment. The vehicle 700 in the embodiment may acquire image information through the camera sensor 2000 for capturing a front image or a surrounding image, use the image information to determine a situation where a lane line is not recognized, and generate a virtual lane line when the lane line is not recognized.

[0562] For example, the camera sensor 2000 may acquire a front image by capturing a view in front of the vehicle 700, and a processor (not shown) may acquire image information by analyzing an object included in the front image.

[0563] For example, when lane lines, adjacent vehicles, obstacles to travel, and objects corresponding to indirect road markings, such as a central divider, a curb, or a tree, are captured in an image captured by the camera sensor 2000, the processor may detect the object and include the detected object in the image information. At this time, the processor may further supplement the image information by acquiring distance information to the object detected by the camera sensor 2000.

[0564] The image information may be information about an object captured in an image. The camera sensor 2000 may include an image sensor and an image processing module.

[0565] The camera sensor 2000 may process a still image or a moving image obtained through an image sensor such as a complementary metal oxide semiconductor (CMOS) or a charge coupled device (CCD).

[0566] The image processing module may process a static image or a moving image acquired by the image sensor to extract necessary information, and transmit the extracted information to the processor.

[0567] At this time, the camera sensor 2000 may include a stereo camera for improving the measurement accuracy of the object and further ensuring information such as the distance between the vehicle 700 and the object, but the present disclosure is not limited thereto.

[0568] Although the embodiments have been mainly described above, these embodiments are only illustrative and do not limit the present disclosure, and it will be understood by those skilled in the art that various modifications and applications not illustrated above are possible without departing from the basic characteristics of the embodiments. For example, each component specifically illustrated in the embodiments can be implemented by modification. In addition, the differences associated with these modifications and applications should be interpreted as being included in the scope of the present disclosure defined in the appended claims.
