[0070] Since the present invention allows various changes and has many embodiments, specific embodiments will be illustrated and described in the accompanying drawings. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that all changes, equivalents and alternatives falling within the spirit and technical scope of the present invention are included in the present invention.

[0071] Although the terms "second", "first", etc. may be used to describe various elements in this article, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, without departing from the scope of the present invention, the second element may be referred to as the first element, and the first element may be similarly referred to as the second element. The term "and / or" includes any combination or any combination of a plurality of associated enumerated items.

[0072] When an element is referred to as being "connected" or "coupled" to another element, it should be understood that the element may be directly connected or coupled to the other element, or other elements may exist between the element and the other element. Conversely, when an element is referred to as being "directly connected" or "directly coupled" to another element, it should be understood that there are no intermediate elements.

[0073] The terms used in this application are only used to describe specific embodiments and are not intended to limit the present invention. Unless the context clearly indicates otherwise, singular expressions include plural expressions. In this application, the terms "including" and "having" are intended to indicate the presence of the features, numbers, steps, movements, components, parts or combinations thereof described in the specification, and are not intended to exclude the presence or addition of one or more other features or numbers, steps, movements, components, parts or combinations thereof.

Terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and will not be interpreted in an idealized or overly formal sense unless explicitly defined herein.

[0075] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings, and components identical or corresponding to each other will be denoted by identical or corresponding reference numerals regardless of the numerals of the drawings, and redundant descriptions will be omitted.

[0076] Figure 1 is a perspective view illustrating a camera module according to an embodiment, Figure 2 is an exploded perspective view illustrating a camera module according to an embodiment, and Figure 3 It is a diagram showing the Figure 1View of the camera module along line AA'.

[0077] Reference Figure 1 and Figure 2 , the camera module 1000 according to the embodiment may include a cover member CV, a first camera actuator 1100, a second camera actuator 1200, and a circuit substrate 1300. In this case, 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.

[0078] The cover CV may cover the first camera actuator 1100 and the second camera actuator 1200. A coupling force between the first camera actuator 1100 and the second camera actuator 1200 may be improved by the cover CV.

[0079] In addition, the cover CV may be formed 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.

[0080] In addition, the first camera actuator 1100 may be an optical image stabilization (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).

[0081] 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".

[0082] The first camera actuator 1100 may change the optical path. In an embodiment, the first camera actuator 1100 may change the optical path in a vertical direction using an internal optical member (e.g., a prism or a mirror). Due to this configuration, even when the thickness of the mobile terminal is reduced, a lens having a thickness greater than that of the mobile terminal may be provided in the mobile terminal by changing the optical path, and thus a magnification function, an auto focus (AF) function, a zoom function, and an OIS function may be performed.

[0083] However, the present invention is not limited thereto, and the first camera actuator 1100 may change the optical path a plurality of times in a vertical direction or at a specific angle.

[0084] The second camera actuator 1200 may be disposed on 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 coupling between the first camera actuator and the second camera actuator may be implemented in one of various ways.

[0085] 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 a single or multiple lenses and may perform an AF function or a zoom function by moving the lenses according to a control signal of a predetermined control unit.

[0086] In addition, a single lens or a plurality of lenses are independently or individually moved along the optical axis direction.

[0087] The circuit substrate 1300 may be provided on a rear end portion of the second camera actuator 1200. The circuit substrate 1300 may be electrically connected to the second camera actuator 1200 and the first camera actuator 1100. In addition, the circuit substrate 1300 may be provided as a plurality of circuit substrates 1300.

[0088] The camera module according to the embodiment may be provided as a single camera module or a plurality of camera modules. For example, the plurality of camera modules may include a first camera module and a second camera module.

[0089] In addition, the first camera module may include a single actuator or a plurality of actuators. For example, the first camera module may include a first camera actuator 1100 and a second camera actuator 1200.

[0090] In addition, the second camera module may be provided in a predetermined housing (not shown) and may include an actuator (not shown) capable of driving the lens portion. The actuator may be a voice coil motor, a microactuator, a silicon actuator, etc., and the actuator may be applied in various ways such as an electrostatic type, a thermal method, a bimorph method, and an electrostatic force method, and the present invention is not limited thereto. In addition, in this specification, the camera actuator may be referred to as an actuator, etc. In addition, a camera module configured as a plurality of camera modules may be installed in one of various electronic devices such as a mobile terminal. In addition, the actuator may be a device that moves or tilts the lens and the optical member. However, hereinafter, the actuator will be described as a concept including a lens or an optical member. In addition, the actuator may be referred to as a "lens transmission device", "lens moving device", "optical member transmission device", "optical member moving device", etc.

[0091] Reference Figure 3 , a camera module according to an embodiment may include a first camera actuator 1100 that performs an OIS function and a second camera actuator 1200 that performs a zoom function and an AF function.

[0092] Light may enter the camera module or the first camera actuator through an aperture area positioned on the upper surface of the first camera actuator 1100. That is, light enters the first camera actuator 1100 along the optical axis direction (e.g., along the X-axis direction based on the incident light), and the optical path may be changed to a vertical direction (e.g., Z-axis direction) by an optical member. In addition, light may pass through the second camera actuator 1200 and may enter the image sensor IS (path) positioned on one end of the second camera actuator 1200. In this specification, as will be described below, the Z-axis direction or the third direction will be described as the optical axis direction.

[0093] In this specification, the lower surface is a side portion 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. The second direction is 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. In addition, the third direction is a direction perpendicular to both the first direction and the second direction. In this case, the third direction (Z-axis direction) corresponds to the direction of the optical axis, and the first direction (X-axis direction) and the second direction (Y-axis direction) are directions perpendicular to the optical axis. In addition, hereinafter, in the description of the first camera actuator and the second camera actuator, the optical axis direction is the third direction (Z-axis direction), and the first camera actuator and the second camera actuator will be described based on this.

[0094] In addition, in this specification, the term "inward" is a direction from the cover CV toward the first camera actuator, and the term "outward" may be a direction opposite to "inward." That is, the first camera actuator and the second camera actuator may be positioned inward from the cover CV, and the cover CV may be positioned outward from the first camera actuator or the second camera actuator.

[0095] In addition, due to this configuration, in the camera module according to the embodiment, the optical path can be changed to relieve the space limitation of the first camera actuator and the second camera actuator. That is, in the camera module according to the embodiment, as the optical path is changed, the thickness of the camera module can be minimized, and thus the optical path can be extended. In addition, it should be understood that the second camera actuator can also provide a wider range of magnifications by controlling the focus in the increased optical path, etc.

[0096] In addition, the camera module according to the embodiment can implement the OIS function by controlling the optical path using the first camera actuator, and thus the occurrence of decentering or tilting phenomenon can be minimized and optimal optical characteristics can be obtained.

[0097] In addition, the second camera actuator 1200 may include an optical system and a lens driving part. For example, at least one of the first lens assembly, the second lens assembly, and the third lens assembly may be provided in the second camera actuator 1200.

[0098] In addition, the second camera actuator 1200 may include a coil and a magnet to perform a high-magnification zoom function and an AF function.

[0099] For example, each of the first lens assembly and the second lens assembly may be a mobile lens that is moved using a coil, a magnet, and a guide pin, and the third lens assembly may be a fixed lens, but the present invention is not limited thereto. For example, the third lens assembly may perform the function of a focuser that collects light to form an image at a specific position, and the first lens assembly may perform the function of a converter that re-forms the image formed by the third lens assembly as a concentrator at another position. At the same time, because the distance to the object or the image distance varies to a large extent, the first lens assembly may be in a state where the magnification varies greatly, and the first lens assembly as a converter may play an important role in changing the focal length or magnification of the optical system. At the same time, the imaging point of the image formed by the first lens assembly as a converter may vary slightly according to the position. 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 that is used to accurately form an image formed by the first lens assembly as a converter at the actual position of the image sensor. For example, each of the first lens assembly and the second lens assembly may be driven by an electromagnetic force generated by the interaction between the coil and the magnet. The above content can be applied to the lens assembly to be described below. In addition, the first lens assembly to the third lens assembly can move along the optical axis direction, that is, the third direction. In addition, the first lens assembly to the third lens assembly can move independently of each other or in combination with each other along the third direction. In the present invention, the first lens assembly and the second lens assembly can move along the optical axis direction. In addition, the third lens assembly can be positioned on the front end portion of the first lens assembly or the rear end portion 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 can be a fixed part. In addition, each of the first lens assembly and the second lens assembly can be a moving part.

[0100] Meanwhile, when the OIS actuator and the AF / zoom actuator are provided according to an embodiment of the present invention, magnetic field interference with the AF / zoom magnet can be prevented when the OIS function is performed. Since the first driving magnet of the first camera actuator 1100 is provided separately 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 stabilization, optical image correction, and shake correction.

[0101] Figure 4a is a perspective view illustrating a first camera actuator according to an embodiment, and Figure 4b is an exploded perspective view illustrating a first camera actuator according to an embodiment.

[0102] Reference Figure 4a and Figure 4b , the first camera actuator 1100 according to the embodiment includes a first housing 1120, a mover 1130, a rotating portion 1140, a first driving portion 1150, a first member 1126, and a second member 1131a.

[0103] The mover 1130 may include a holder 1131 and an optical member 1132 installed in the holder 1131. In addition, the rotating part 1140 may include an inclined guide part 1141, and a second magnetic part 1142 and a first magnetic part 1143 having the same polarity or different polarities to press the inclined guide part 1141. For example, in the first magnetic part 1143 and the second magnetic part 1142, the polarities of the surfaces facing each other may be the same. In addition, the first driving part 1150 includes a driving magnet 1151, a driving coil 1152, a Hall sensor part 1153, a first substrate part 1154, and a yoke part 1155.

[0104] First, the first camera actuator 1100 may include a protective cover (not shown). The protective cover (not shown) may be positioned at the outermost portion of the first camera actuator 1100 and positioned to surround a rotating portion 1140 and a first driving portion 1150 to be described below.

[0105] Such a protective cover (not shown) can block or reduce electromagnetic waves generated from the outside. That is, the protective cover (not shown) can reduce the number of malfunctions that occur in the rotating part 1140 or the first driving part 1150.

[0106] The first housing 1120 may be positioned in a protective cover (not shown). When the protective cover is not present, the first housing 1120 may be positioned at the outermost portion of the first camera actuator.

[0107] In addition, the first housing 1120 may be positioned inside a first base plate portion 1154 to be described below. The first housing 1120 may be fitted to a protective cover (not shown) or engaged with the protective cover to be fastened to the protective cover.

[0108] The first case 1120 may include a first case side portion 1121, a second case side portion 1122, a third case side portion 1123, and a fourth case side portion 1124. Details thereof will be described below.

[0109] The first member 1126 may be disposed in the first housing 1120. The second member 1131a may pass through some areas of the first member 1126. The first member 1126 may be disposed in the housing. The first member 1126 may be combined with or separated from the first housing 1120.

[0110] The mover 1130 includes a holder 1131 and an optical member 1132 installed in the holder 1131 .

[0111] The holder 1131 may be installed in the receiving portion 1125 of the first housing 1120. The holder 1131 may include first to fourth holder 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 holder 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.

[0112] In addition, the holder 1131 may include a second member 1131a disposed in the fourth mounting groove. The second member 1131a may pass through the first member 1126 and may be coupled to the holder 1131. Details thereof will be described below.

[0113] The optical member 1132 may be mounted in the holder 1131. To this end, the holder 1131 may have a mounting surface, and the mounting 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, although the optical member 1132 is described based on a prism, it may be provided as a plurality of lenses as in the above-described embodiment. Alternatively, the optical member 1132 may be formed by a plurality of lenses and a prism or a mirror. In addition, the optical member 1132 may include a reflecting portion provided therein. However, the present invention is not limited thereto.

[0114] In addition, the optical member 1132 can reflect light reflected from the outside (e.g., an object) into the camera module. In other words, the optical member 1132 can relieve the space limitation of the first camera actuator and the second camera actuator by changing the optical path of the reflection. Therefore, it should be understood that the camera module can also provide a high magnification by extending the optical path while minimizing the thickness of the camera module.

[0115] In addition, the second member 1131a can be coupled to the retainer 1131. The second member 1131a can be disposed outside the retainer 1131 and inside the housing. In addition, the second member 1131a can be mounted in an additional groove positioned in an area other than the fourth mounting groove in the outer surface of the fourth retainer in the retainer 1131. Therefore, the second member 1131a can be coupled to the retainer 1131, and at least a portion of the first member 1126 can be positioned between the second member 1131a and the retainer 1131. For example, at least a portion of the first member 1126 can be disposed in a space formed between the second member 1131a and the retainer 1131. In addition, as described above, the second member 1131a can pass through a hole formed in the first member 1126.

[0116] In addition, the second member 1131a may be formed in a structure separate from the holder 1131. Due to this configuration, the first camera actuator may be easily assembled as will be described below. Alternatively, the second member 1131a may be formed integrally with the holder 1131, but the second member 1131a will be described below as a separate structure.

[0117] The rotating portion 1140 includes an inclined guide portion 1141 , and a second magnetic portion 1142 and a first magnetic portion 1143 having the same polarity to press the inclined guide portion 1141 .

[0118] 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 retainer 1131 and the first member 1126. Therefore, the inclined guide portion 1141 may be coupled to the mover 1130 of the retainer 1131 and the first housing 1120. However, unlike the above, in the present embodiment, the inclined guide portion 1141 may be disposed between the first member 1126 and the retainer 1131. Specifically, the inclined guide portion 1141 may be positioned between the first member 1126 and the fourth mounting groove of the retainer 1131. For example, at least a portion of the inclined guide portion 1141 may be positioned in the fourth mounting groove.

[0119] The second member 1131a, the first member 1126, the inclined guide portion 1141 and the retainer 1131 can be arranged in sequence in the third direction (Z-axis direction). In addition, the second magnetic portion 1142 and the first magnetic portion 1143 can be installed in the first groove gr1 formed in the second member 1131a and the second groove gr2 formed in the first member 1126, respectively. In the present embodiment, the positions of the first groove gr1 and the second groove gr2 can be different from the positions of the first groove and the second groove. 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 in the first member 1126 to correspond to the first groove gr1, and the second groove gr2 is connected to the first shell 1120. Therefore, these terms can be described interchangeably with each other. In addition, the first groove and the second groove can be grooves as described above. Alternatively, each of the first groove and the second groove can be replaced by the type of hole.

[0120] 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 first axis tilt and the second axis tilt which will be described below.

[0121] 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 to each other. The first protrusion and the second protrusion may include a plurality of protrusions, a spherical portion, or a rolling member.

[0122] In addition, as described above, the first 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.

[0123] The second magnetic portion 1142 and the first magnetic portion 1143 may have the same polarity. For example, the second magnetic portion 1142 may be a magnet having an N pole, and the first magnetic portion 1143 may be a magnet having an N pole. Conversely, the second magnetic portion 1142 may be a magnet having an S pole, and the first magnetic portion 1143 may be a magnet having an S pole.

[0124] For example, a first pole surface of the first magnetic portion 1143 and a second pole surface of the second magnetic portion 1142 facing the first pole surface may have the same polarity.

[0125] The second magnetic part 1142 and the first magnetic part 1143 can generate a repulsive force between them due to polarity. Due to this configuration, the repulsive force can be applied to the second member 1131a or the retainer 1131 connected to the second magnetic part 1142 and the first member 1126 or the first shell 1120 connected 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 connected to the second member 1131a. Therefore, the inclined guide part 1141 set between the second member 1131a and the first member 1126 can be pressed by the repulsive force. In other words, the repulsive force can maintain the state in which the inclined guide part 1141 is positioned between the retainer 1131 and the first shell 1120 (or the first member 1126). Due to this configuration, the relative position between the mover 1130 and the first shell 1120 can be maintained even when performing X-axis tilt or Y-axis tilt. In addition, the inclined guide portion can be in close contact with the first member 1126 and the retainer 1131 by the repulsive force between the first magnetic portion 1143 and the second magnetic portion 1142. In other words, the repulsive force generated by the first magnetic portion 1143 and the second magnetic portion 1142 can be a force for maintaining the relative position between the retainer 1131 and the first shell 1120.

[0126] The first driving part 1150 includes a driving magnet 1151, a driving coil 1152, a Hall sensor part 1153, a first substrate part 1154 and a yoke part 1155. The contents thereof will be described below. In addition, the yoke part 1155 in the first camera actuator may be referred to as a "first yoke part". In addition, the yoke part in the second camera actuator may be referred to as a "second yoke part".

[0127] Figure 5a is a perspective view illustrating a first camera actuator according to an embodiment, Figure 5b It is a diagram showing the Figure 5a a view of the first camera actuator of line PP', and Figure 5c It is a diagram showing the Figure 5a View of the first camera actuator along line QQ'.

[0128] Reference Figure 5a to Figure 5c , a third coil 1152a may be positioned in the first housing side portion 1121, and a third magnet 1151a may be positioned on the first holder outer surface 1131S1 of the holder 1131. Therefore, the third coil 1152a and the third magnet 1151a may be positioned to face each other. At least a portion of the third magnet 1151a may overlap with the third coil 1152a in the second direction (Y-axis direction).

[0129] In addition, a fourth coil 1152b may be positioned in the second housing side portion 1122, and a fourth magnet 1151b may be positioned on the second holder outer surface 1131S2 of the holder 1131. Therefore, the fourth coil 1152b and the fourth magnet 1151b may be positioned to face each other. At least a portion of the fourth magnet 1151b may overlap with the fourth coil 1152b in the second direction (Y-axis direction).

[0130] In addition, the third coil 1152a and the fourth coil 1152b may overlap in the second direction (Y-axis direction), and the third magnet 1151a and the fourth magnet 1151b may overlap in the second direction (Y-axis direction).

[0131] Due to this configuration, the electromagnetic force applied to the outer surfaces of the holder (the first holder outer surface and the second holder outer surface) is applied along an axis parallel to the second direction (Y-axis direction), and thus X-axis tilting can be performed accurately and precisely.

[0132] 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 installed in the second protrusion groove PH2 formed in one side surface of the first member 1126. In addition, when the X-axis tilt is performed, 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.

[0133] In addition, the first hall sensor 1153a may be positioned externally for electrical connection and coupling with the first substrate portion 1154 as described above. However, the present invention is not limited to such a position.

[0134] In addition, a fifth coil 1152c may be positioned in the third housing side portion 1123, and a fifth magnet 1151c may be positioned on the third holder outer surface 1131S3 of the holder 1131. At least a portion of the fifth coil 1152c and the fifth magnet 1151c may overlap in the first direction (X-axis direction). Therefore, the strength of the electromagnetic force between the fifth coil 1152c and the fifth magnet 1151c may be easily controlled.

[0135] 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 installed in the fourth mounting groove 1131S4a of the fourth holder outer surface. As described above, the fourth mounting groove 1131S4a may include the first area AR1, the second area AR2, and the third area AR3.

[0136] The second member 1131a may be disposed in the first area AR1, and the second member 1131a may include a first groove gr1 formed in the 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 mounting groove 1131S4a (RF2') of the retainer 1131 through the second member 1131a. 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.

[0137] 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 in 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 using the repulsive forces RF1 and RF2' generated. Therefore, the connection between the retainer 1131, the first housing 1120 and the inclined guide portion 1141 may be maintained, even after the X-axis tilt or Y-axis tilt of the retainer is performed using a current applied to the third coil and the fourth coil or the fifth coil 1152c.

[0138] 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 protruding portion PR1 and a second protruding portion PR2. In this case, the first protruding portion PR1 and the second protruding portion PR2 may also be disposed on the second surface 1141b and the first surface 1141a of the base BS, respectively. As described above, in other embodiments to be described below, the first protruding portion PR1 and the second protruding portion PR2 may be positioned on surfaces facing each other on the base BS in various ways.

[0139] The first protrusion groove PH1 can be positioned in the fourth mounting groove 1131S4a. In addition, the first protrusion PR1 of the inclined guide portion 1141 can be accommodated in the first protrusion groove PH1. Therefore, the first protrusion PR1 can contact the first protrusion groove PH1. The maximum diameter of each first protrusion groove in the first protrusion groove PH1 can correspond to the maximum diameter of each first protrusion in the first protrusion PR1. This can also be applied to the second protrusion groove PH2 and the second protrusion PR2. That is, the maximum diameter of each second protrusion groove in the second protrusion groove PH2 can correspond to the maximum diameter of each second protrusion in the second protrusion PR2. In addition, the second protrusion PR2 can contact the second protrusion groove PH2. Due to this configuration, the first axis tilting centered on the first protrusion PR1 and the second axis tilting centered on the second protrusion PR2 can be easily performed, and the radius of the tilting can be increased.

[0140] In addition, the tilt guide portion 1141 can be arranged in parallel with the second member 1131a and the first member 1126 in the third direction (Z-axis direction), and therefore, 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 fifth coil 1152c or the fifth magnet 1151c in the first direction (X-axis direction). That is, each protrusion as the tilt center axis in the camera actuator according to the embodiment 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 of the holder tilting, and the consumption of the current applied to the coil portion, etc. to tilt the holder, and thus the power consumption can be reduced and the reliability of the device can be improved.

[0141] In addition, the second magnetic portion 1142 and the first magnetic portion 1143 may not overlap with the fifth coil 1152c or the optical member 1132 in the first direction (X-axis direction). In other words, in an embodiment, the second magnetic portion 1142 and the first magnetic portion 1143 may be arranged to be spaced apart from the fifth coil 1152c or the optical member 1132 in the third direction (Z-axis direction). Therefore, in the fifth coil 1152c, the magnetic force received from the second magnetic portion 1142 and the first magnetic portion 1143 can be minimized. Therefore, the camera actuator according to the embodiment can easily perform vertical drive (Y-axis tilt) and minimize power consumption.

[0142] In addition, as described above, the second Hall sensor 1153b positioned inside the fifth coil 1153c can detect changes in magnetic flux to perform relative position sensing between the fifth magnet 1151c and the second Hall sensor 1153b. In this case, the offset voltage of the second Hall sensor 1153b can change according to the influence of the magnetic field formed by the second magnetic portion 1142 and the first magnetic portion 1143.

[0143] In the first camera actuator according to the embodiment, 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 may be sequentially arranged in the third direction. 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 sequentially arranged.

[0144] In addition, in an embodiment, in the third direction, the separation distance between the second magnetic portion 1142 and the first magnetic portion 1143 and the holder 1131 (or the optical member 1132) can be greater than the separation distance between the second magnetic portion 1142 and the first magnetic portion 1143 and the inclined guide portion 1141. Therefore, the second Hall sensor 1153b below the holder 1131 can 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 formed by the second magnetic portion 1142 and the first magnetic portion 1143 on the second Hall sensor 1153b can be minimized to prevent the Hall voltage from being concentrated and saturated to a positive voltage or a negative voltage. That is, this configuration allows the Hall electrode to have a range for performing Hall calibration. In addition, the temperature is also affected by the electrode of the Hall sensor, and the resolution of the camera lens will change according to the temperature, but in an embodiment, since the Hall voltage is prevented from being concentrated to a positive voltage or a negative voltage, the resolution of the lens is also corrected accordingly, and the resolution can be easily prevented from decreasing.

[0145] In addition, a circuit for compensating for the offset of the output power (ie, the Hall voltage) of the second Hall sensor 1153b can be easily designed.

[0146] In addition, according to an embodiment, a partial area of ​​the inclined guide portion 1141 may be positioned outside the fourth holder outer surface of the holder 1131 .

[0147] In addition to the first protruding portion PR1 and the second protruding portion PR2, the inclined guide portion 1141 can be installed in the fourth installation groove 1131S4a based on the base BS. In other words, the length of the base BS in the third direction (Z-axis direction) can be smaller than the length of the fourth installation groove 1131S4a in the third direction (Z-axis direction). Due to this configuration, miniaturization can be facilitated.

[0148] 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 mounting 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 relative to the retainer 1131 in a direction opposite to the third direction (Z-axis direction). In other words, 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).

[0149] 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 on the front surface 1126es of the first member 1126 toward the third direction (Z-axis direction). Alternatively, the front surface 1131aes of the second member 1131a according to the embodiment may be positioned inside the front surface 1126es of the first member 1126. To this end, the first member 1126 may have a structure extending inward and bending. In addition, a partial area of ​​the second member 1131a may be positioned in a groove formed in the extended and bent structure of the first member 1126.

[0150] Due to this configuration, the second member 1131a is positioned inside the first member 1126, and thus space efficiency can be improved and miniaturization can be achieved. In addition, even when driving (tilting or rotation of the mover 1130) is performed by electromagnetic force, the second member 1131a does not protrude outward from the first member 1126, and thus the second member 1131a can be prevented from contacting surrounding elements. Therefore, its reliability can be improved.

[0151] In addition, a predetermined separation space may exist between the second magnetic portion 1142 and the first magnetic portion 1143. In other words, the second magnetic portion 1142 and the first magnetic portion 1143 may have the same polarity and may face each other.

[0152] Figure 6ais a perspective view illustrating a first camera actuator according to an embodiment, Figure 6b It is a diagram showing the Figure 6a a view of the first camera actuator in line SS', and Figure 6c It's a picture. Figure 6b An exemplary view of the movement of the first camera actuator shown in FIG.

[0153] Reference Figures 6a to 6c , Y-axis tilt may be performed in the first camera actuator according to the embodiment. That is, rotation may be performed along the first direction (X-axis direction) to implement the OIS function.

[0154] In an embodiment, the fifth magnet 1151c disposed in the lower portion of the holder 1131 may generate an electromagnetic force with the fifth coil 1152c to tilt or rotate the mover 1130 with respect to the second direction (Y-axis direction).

[0155] Specifically, the repulsive force between the second magnetic portion 1142 and the first magnetic portion 1143 is transmitted to the second member 1131a and the first member 1126, and is finally transmitted to the inclined guide portion 1141 provided 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 due to the repulsive force.

[0156] In addition, the second protruding portion PR2 may be supported by the first member 1126. In this case, in an embodiment, the inclined guide portion 1141 may be rotated or tilted relative to the second protruding portion PR2 protruding toward the first member 1126 as a reference axis (or rotation axis), that is, rotated or tilted relative to the second direction (Y-axis direction). In other words, the inclined guide portion 1141 may be rotated or tilted along the first direction (X-axis direction) relative to the second protruding portion PR2 protruding toward the first member 1126 as a reference axis (or rotation axis).

[0157] For example, when the mover 1130 rotates by a first angle θ1 in the X-axis direction (X1→X1a) by first electromagnetic forces F1A and F1B between the fifth magnet 1151c disposed in the third mounting groove and the fifth coil 1152c disposed on the third substrate side portion, the OIS function may be implemented.

[0158] On the contrary, when the mover 1130 rotates by a first angle θ1 in a direction opposite to the X-axis direction (X1→X1b) by the first electromagnetic forces F1A and F1B between the fifth magnet 1151c set in the third mounting groove and the fifth coil 1152c set on the side portion of the third substrate, the OIS function can be implemented.

[0159] The first angle θ1 may be ±1° to ±3°. However, the present invention is not limited thereto.

[0160] In the first camera actuator according to various embodiments below, the electromagnetic force may be generated in the described direction to move the mover, or the electromagnetic force may move the mover even when the electromagnetic force is generated in another direction. That is, the direction of the electromagnetic force described is 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 be applied in the third direction or in the direction opposite to the third direction.

[0161] In addition, the center MC1 of the second magnetic portion 1142 and the center MC2 of the first magnetic portion 1143 can be arranged side by side in the third direction (Z-axis direction). In other words, the center line TL1 connecting the center MC1 of the second magnetic portion 1142 and the center MC2 of the first magnetic portion 1143 can be parallel to the third direction (Z-axis direction).

[0162] In addition, the bisector TL2 that bisects the second protruding portion PR2 and corresponds to the third direction (Z-axis direction) may be parallel to the center line TL1. In other words, the bisector TL2 may be a line that bisects the second protruding portion PR2 in the first direction (X-axis direction), and may be set as a plurality of bisectors TL2.

[0163] In an embodiment, the bisector TL2 can be set 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. Due to this configuration, the separation distance from the bisector TL2 to the fifth coil 1152c or the fifth magnet 1151c increases, and thus the two-axis tilting of the retainer can be performed more accurately. In addition, when no current is applied to the coil, the position of the retainer can also be maintained.

[0164] More specifically, since the center MC1 of the second magnetic portion 1142 and the center MC2 of the first magnetic portion 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 portion 1142 and the first magnetic portion 1143 can be applied spaced apart from the bisector TL2 corresponding to the optical axis in the first direction (X-axis direction). In addition, the force generates momentum on the mover 1130. However, when the center MC1 of the second magnetic portion 1142 and the center MC2 of the first magnetic portion 1143 are positioned on the bisector TL2, there is a problem that the positions of the tilt guide portion and the second magnetic portion 1142 cannot be maintained when calibration is performed after tilting is performed. That is, in the camera actuator according to the embodiment, since the center MC1 of the second magnetic portion 1142 and the center MC2 of the first magnetic portion 1143 are not set on the bisector TL2, the positions of the tilt guide portion and the second magnetic portion 1142 can be maintained after tilting or rotating.

[0165] In another example, 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).

[0166] 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.

[0167] Therefore, the separation distance from the bisector TL2 to the fifth coil 1152c or the fifth magnet 1151c increases, and the two-axis tilting of the holder can be performed more accurately. In addition, when no current is applied to the coil, the position of the holder can also be maintained.

[0168] In addition, the lengths of the second magnetic portion 1142 and the first magnetic portion 1143 in the first direction (X-axis direction) may be different.

[0169] In an embodiment, the area of ​​the second magnetic portion 1142 coupled to the second member 1131a and tilted 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 between virtual straight lines extending from the two ends of the second magnetic portion 1142 along the third direction.

[0170] Due to this configuration, when tilting or rotating is performed, even when one magnetic part (e.g., the second magnetic part) is tilted, it is easy to prevent the generation of forces other than the vertical force due to the tilt. That is, even when the second magnetic part is tilted vertically together with the mover 1130, the second magnetic part cannot receive a force (e.g., a repulsive force or an attractive force) applied to resist the tilt from the first magnetic part 1143. Therefore, the driving efficiency can be improved.

[0171] Figure 7a It is a diagram showing the Figure 6a a view of the first camera actuator in line RR', and Figure 7b It's a picture. Figure 7a Schematic view of the movement of the first camera actuator shown in .

[0172] Reference Figure 7a and Figure 7b , X-axis tilting can be performed. That is, the mover 1130 can be tilted or rotated along the Y-axis direction to achieve the OIS function.

[0173] In an embodiment, the third magnet 1151a and the fourth magnet 1151b disposed in the holder 1131 may generate electromagnetic force with the third coil 1152a and the fourth coil 1152b, respectively, to tilt or rotate the tilt guide portion 1141 and the mover 1130 relative to the first direction (X-axis direction).

[0174] 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 due to the repulsive force.

[0175] In addition, the first-first protrusion portion PR1a and the first-second protrusion portion 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 mounting groove 1131S4a of the holder 1131. In addition, in an embodiment, the tilt guide portion 1141 may be rotated or tilted relative to the first protrusion portion PR1 protruding toward the holder 1131 (for example, in the third direction) as a reference axis (or rotation axis), that is, rotated or tilted relative to the first direction (X-axis direction).

[0176] For example, when the mover 1130 is rotated along the Y-axis direction (Y1→Y1a) by a second angle θ2 by the second electromagnetic force F2A and F2B between the third magnet 1151a and the fourth magnet 1151b disposed in the first mounting groove and the third coil 1152a and the fourth coil 1152b disposed on the first substrate side portion and the second substrate side portion, the OIS function can be implemented. In addition, when the mover 1130 is rotated along the Y-axis direction (Y1→Y1b) by a second electromagnetic force F2A and F2B between the third magnet 1151a and the fourth magnet 1151b disposed in the first mounting groove and the third coil 1152a and the fourth coil 1152b disposed on the first substrate side portion and the second substrate side portion, the OIS function can be implemented. The second angle θ2 may be ±1° to ±3°. However, the present invention is not limited thereto.

[0177] In addition, as described above, the electromagnetic force generated by the third magnet 1151a and the fourth magnet 1151b and the third coil 1152a and the fourth coil 1152b can be applied in the third direction or in the direction opposite to the third direction. For example, the electromagnetic force can be generated from the left side portion of the mover 1130 in the third direction (Z-axis direction) and applied from the right side portion of the mover 1130 in the direction opposite to the third direction (Z-axis direction). Therefore, the mover 1130 can rotate relative to the first direction. Alternatively, the mover 1130 can move in the second direction.

[0178] As described above, the first actuator according to the embodiment can control the mover 1130 to rotate in the first direction (X-axis direction) or the second direction (Y-axis direction) through the electromagnetic force between the driving magnet in the holder and the driving coil set in the first shell, so as to minimize the occurrence of eccentricity or tilt when realizing the OIS function and provide the best optical characteristics. In addition, as described above, the term "Y-axis tilt" is a rotation or tilt along the first direction (X-axis direction), and the term "X-axis tilt" is a rotation or tilt along the second direction (Y-axis direction).

In addition, the second camera actuator 1200 may further include a second protective cover (not shown) and an elastic portion (not shown).

[0181] A second protective cover (not shown) is positioned on an area (e.g., the outermost portion) of the second camera actuator 1200 to surround the components (lens portion 1220, second housing 1230, second driving portion 1250, base portion 1260, second substrate portion 1270, and image sensor IS) to be described below.

[0182] The second protective cover (not shown) may block or reduce electromagnetic waves generated from the outside. Therefore, the occurrence of malfunction in the second driving part 1250 may be reduced.

[0183] The lens portion 1220 may be positioned in a second protective cover (not shown). The lens portion 1220 may be moved in a third direction (Z-axis direction or optical axis direction). Thus, an AF function or a zoom function may be performed.

[0184] In addition, the lens portion 1220 may be positioned in the second housing 1230. Therefore, at least a portion of the lens portion 1220 may be moved in the second housing 1230 in the optical axis direction or the third direction (Z-axis direction).

[0185] Specifically, the lens portion 1220 may include a lens group 1221 and a moving assembly 1222 .

[0186] First, the lens group 1221 may include at least one lens. In addition, the lens group 1221 may be provided as a plurality of lens groups 1221 , but will be described based on one lens group 1221 .

[0187] The lens group 1221 may be coupled to the moving assembly 1222 , and may be moved in a third direction (Z-axis direction) by an electromagnetic force generated by a first magnet 1252 a and a second magnet 1252 b coupled to the moving assembly 1222 .

[0188] 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 arranged on the rear end portion of the third lens group 1221c.

[0189] The first lens group 1221a may be fixedly coupled to the second-first housing. In other words, the first lens group 1221a may not move along the optical axis direction.

[0190] 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 first lens assembly 1222a and the second lens group 1221b may move to adjust magnification.

[0191] The third lens group 1221c may be coupled to the second lens assembly 1222b to move in a third direction or an optical axis direction. The third lens group 1221c may move to adjust a focus or perform AF.

[0192] However, the present invention is not limited to such a number of lens groups, and the fourth lens group 1221d described above may not exist, or an additional lens group may be provided in addition to the fourth lens group 1121d.

[0193] The moving assembly 1222 may include an aperture area surrounding the lens group 1221. The moving assembly 1222 can be used interchangeably with the lens assembly. In addition, the moving assembly 1222 can be coupled to the lens group 1221 in one of various ways. In addition, the moving assembly 1222 may include grooves in the side surface of the moving assembly 1222, and may be coupled to the first magnet 1252a and the second magnet 1252b through these grooves. A coupling member or the like may be applied in the grooves.

[0194] In addition, an elastic portion (not shown) may be coupled to each of the upper end portion and the rear end portion of the moving assembly 1222. Therefore, the moving assembly 1222 may be supported by the elastic portion (not shown) when moving in the third direction (Z-axis direction). In other words, the position of the moving assembly 1222 may be maintained in the third direction (Z-axis direction). The elastic portion (not shown) may be formed by one of various elastic elements, such as a leaf spring.

[0195] The moving assembly 1222 can be positioned in the second housing 1230, and can include a first lens assembly 1222a and a second lens assembly 1222b. In addition, the moving assembly 1222 can be set as a plurality of moving assemblies 1222, and at least one moving assembly 1222 can move along the optical axis direction. In the following, at least one of the first lens assembly 1222a and the second lens assembly 1222b may include a lens holder having a lens, a side plate in which spherical portions B1 and B2 are seated, a track portion having a wing-shaped portion extending from the side plate, and a bonding member AM disposed between the track portion and the lens holder. The bonding member AM can be cured by light (e.g., ultraviolet (UV) light) after active alignment or optical axis alignment. For example, the bonding member AM may include epoxy resin, etc. The details will be described below.

[0196] The area of ​​the second lens assembly 1222b where the third lens group is installed can be positioned on the rear end of the first lens assembly 1222a. In other words, the area of ​​the second lens assembly 1222b where the third lens group 1221c is installed can be positioned between the area of ​​the first lens assembly 1222a where the second lens group 1221b is installed and the image sensor.

[0197] The first lens assembly 1222a and the second lens assembly 1222b may be mounted inside the second-second housing. For example, the recess in which the spherical member of the first lens assembly 1222a is disposed may be positioned to face the first side portion. In addition, the recess in which the spherical member of the second lens assembly 1222b is disposed may be positioned to face the second side portion. The details will be described below.

[0198] In addition, the second driving magnet can be installed on the outer surface of the first lens assembly 1222a and the outer surface of the second lens assembly 1222b. For example, the second magnet 1252b can be installed on the outer surface of the second lens assembly 1222b. The first magnet 1252a can be installed on the outer surface of the first lens assembly 1222a.

[0199] The second housing 1230 may be disposed between the lens portion 1220 and the second protective cover (not shown). In addition, the second housing 1230 may be disposed to surround the lens portion 1220.

[0200] 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. The second-first housing 1231 may be positioned in front of the second-second housing 1232.

[0201] In addition, the second-second housing 1232 may be positioned on a rear end portion of the second-first housing 1231. The lens portion 1220 may be installed in the second-second housing 1232.

[0202] Holes may be formed in the side portion of the second housing 1230 (or the second-second housing 1232 ). The first coil 1251 a and the second coil 1251 b may be disposed in the holes. The holes may be positioned to correspond to the grooves of the moving component 1222 .

[0203] 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 relative to a third direction. The second drive coil 1251 may be positioned on the first side portion 1232a and the second side portion 1232b. In addition, the second substrate portion 1270 may be mounted on each of the outer surface of the first side portion 1232a and the outer surface of the second side portion 1232b. In other words, the first substrate 1271 may be positioned on the outer surface of the first side portion 1232a, and the second substrate 1272 may be positioned on the outer surface of the second side portion 1232b.

[0204] In addition, as another example, the first guide groove and the second guide groove of the recess facing the first lens assembly 1222a (the mounting groove in which the first spherical member and the second spherical member are mounted) can be positioned in the first side portion. In addition, the first guide groove and the second guide groove of the recess facing the second lens assembly 1222b can be positioned in the second side portion. In this case, a separate component (e.g., a guide portion) including the first guide groove and the second guide groove can be connected to the second-second shell 1232. However, the present embodiment will be described with reference to the integrated structure in which the first guide groove and the second guide groove are formed in the second-second shell 1232. In addition, in Figure 27 to Figure 3 8, a structure in which the second housing (or second-second housing) is separated from the first guide groove and the second guide groove will be described.

[0205] In addition, similar to another example, the first guide portion and the second guide portion can be positioned to correspond to each other. For example, the first guide portion and the second guide portion can be positioned to be opposite to each other in the third direction (Z-axis direction). In addition, at least a portion of the first guide portion and the second guide portion can overlap in the second direction (Y-axis direction).

[0206] Each of the first guide portion and the second guide portion 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 installed 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 portion or the guide groove of the second guide portion along the third direction (Z-axis direction).

[0207] Alternatively, the first ball B1 or the second ball B2 may move in the third direction along a track formed inside the first side portion 1232 a of the second housing 1230 or a track formed inside the second side portion 1232 b of the second housing 1230 .

[0208] Therefore, the first lens assembly 1222a and the second lens assembly 1222b may move in the third direction.

[0209] According to an embodiment, each of the first spherical members B1 may be disposed on the first lens assembly 1222a or the second lens assembly 1222b. Each of the second spherical members B2 may be disposed below 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.

[0210] In addition, the second-second shell 1232 may include first guide grooves GG1a and GG2a facing the first recess RS1. In addition, the second-second shell 1232 may include second guide grooves GG1b and GG2b facing the second recess RS2. The first guide grooves GG1a and GG2a and the second guide grooves GG1b and GG2b may be grooves extending in a third direction (Z-axis direction). In addition, the first guide grooves GG1a and GG2a and the second guide grooves GG1b and GG2b may be grooves having different shapes. For example, the first guide grooves GG1a and GG2a may be grooves whose side surfaces are inclined, and the second guide grooves GG1b and GG2b may be grooves whose side surfaces are perpendicular to the lower surface.

[0211] The first magnet and the first coil can be positioned on the first side portion. In addition, the second magnet and the second coil can be positioned on the second side portion. In addition, the second magnet 1252b can be positioned to face the second coil 1251b. In addition, the first magnet 1252a can be positioned to face the first coil 1251a.

[0212] The elastic part (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, as described above, the first elastic member (not shown) and the second elastic member (not shown) may be formed by a leaf spring. In addition, the first elastic member (not shown) and the second elastic member (not shown) may provide elasticity for movement of the moving assembly 1222. However, the present invention is not limited to such positioning of the elastic part, and the elastic part may be provided at various positions.

[0213] In addition, the second driving part 1250 can provide a driving force for moving the lens part 1220 along a third direction (Z-axis direction). The second driving part 1250 may include a second driving coil 1251 and a second driving magnet 1252. In addition, the second driving part 1250 may also include a second Hall sensor part. The second Hall sensor part 1253 may include at least one fourth Hall sensor 1253a, and may be positioned on the inside or outside of the second driving coil 1251.

[0214] The moving component may move in the third direction (Z-axis direction) by the electromagnetic force generated between the second driving coil 1251 and the second driving magnet 1252 .

[0215] The second driving coil 1251 may include a first coil 1251a and a second coil 1251b. The first coil 1251a and the second coil 1251b may be disposed in a hole formed in a side portion of the second housing 1230. The first coil 1251a and the second coil 1251b may be electrically connected to the second substrate portion 1270. Therefore, the first coil 1251a and the second coil 1251b may receive current through the second substrate portion 1270.

[0216] The second driving magnet 1252 may include a first magnet 1252a and a second magnet 1252b. The first magnet 1252a and the second magnet 1252b may be disposed in a groove of the moving component 1222 and may be positioned to correspond to the first coil 1251a and the second coil 1251b.

[0217] The base portion 1260 may be positioned between the lens portion 1220 and the image sensor IS. Components such as filters may be fixed to the base portion 1260. In addition, the base portion 1260 may be provided to surround the image sensor. Due to this configuration, the image sensor is protected from foreign matter, etc., and thus the reliability of the device may be improved. However, in some of the following drawings, description will be made without the base portion 1260. However, the present invention may not be limited to this structure.

[0218] In addition, the second camera actuator 1200 may be a zoom actuator or an AF actuator. For example, the second camera actuator supports one or more lenses and may perform at least one of an AF function and a zoom function by moving the lenses according to a control signal of a predetermined control unit.

[0219] In addition, the second camera actuator may be a fixed zoom actuator or a continuous zoom actuator. For example, the second camera actuator may move the lens group 1221.

[0220] In addition, the second camera actuator may be formed by a plurality of lens assemblies. For example, in the second camera actuator, 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. The above contents may be applied hereto. Therefore, the second camera actuator may use the second driving portion to perform a high-power zoom function. For example, the first lens assembly 1222a and the second lens assembly 1222b may be moving lenses moved by the second driving portion and the guide pin (not shown), and the third lens assembly (not shown) may be a fixed lens, but the present invention is not limited thereto. For example, the third lens assembly (not shown) may perform the function of a focuser that collects light to form an image at a specific position, and the first lens assembly may perform the function of a converter that re-forms the image formed by the third lens assembly (not shown) at another position. At the same time, because the distance to the object or the image distance varies to a large extent, the first lens assembly may be in a state where the magnification varies greatly, and the first lens assembly as a converter may play an important role in changing the focal length or magnification of the optical system. At the same time, the imaging point of the image formed by the first lens assembly as a converter may vary slightly depending on the position. 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 image formed by the first lens assembly as a converter at the actual position of the image sensor. However, the configuration of the present embodiment will be described based on the following drawings.

[0221] The image sensor may be positioned inside or outside the second camera actuator. In an embodiment, as illustrated, the image sensor may be positioned outside the second camera actuator. For example, the image sensor may be positioned on a circuit substrate. The image sensor may receive light and convert the received light into an electrical signal. In addition, the image sensor may be formed in the form of a plurality of pixels of an array type. In addition, the image sensor may be positioned on an optical axis.

[0222] The second substrate portion 1270 may be in contact with each of the side portions of the second shell. For example, the second substrate portion 1270 may be positioned on the second shell, in particular, on each of the outer surface of the first side portion (first side surface) and the outer surface of the second side portion (second side surface) of the second-second shell, and the second substrate portion 1270 may be in contact with each of the first side surface and the second side surface.

[0223] The stopper portion ST includes a first stopper ST1 disposed on one end portion in the second-second housing 1232 and a second stopper ST2 disposed on the other end portion in the second-second housing 1232. The first stopper ST1 and the second stopper ST2 may be sequentially disposed in the optical axis direction.

[0224] In addition, the first stopper ST1 may be provided as a plurality of first stoppers ST1 disposed on the moving path of the first lens assembly and the moving path of the second lens assembly. For convenience, the first-first stopper ST1a and the first-second stopper ST1b will be described. Similarly, the second stopper ST2 may be provided as a plurality of second stoppers ST2 disposed on the moving path of the first lens assembly and the moving path of the second lens assembly. In addition, the second-first stopper ST2a and the second-second stopper ST2b will be described.

[0225] The first-first stopper ST1a and the second-first stopper ST2a may be positioned on a moving path of the first lens assembly. The second-second stopper ST1b and the second-second stopper ST2b may be positioned on a moving path of the second lens assembly.

[0226] 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.

[0227] 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 the fact that the movable distance (stroke) of the first lens assembly is smaller than the movable distance (stroke) of the second lens assembly.

[0228] For example, the second yoke portion or yoke portion YK may be disposed outside the second driving portion. The second yoke portion YK may include a first yoke YK1 and a second yoke YK2.

[0229] 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 to correspond to each other with respect to the optical axis.

[0230] The first yoke YK1 can be positioned adjacent to the first coil 1251a. The second yoke YK2 can be positioned adjacent to the second coil 1251b. The first coil 1251a and the second coil 1251b can be positioned between the first yoke YK1 and the second yoke YK2. In addition, the first yoke YK1, the first coil 1251a, the second coil 1251b and the second yoke YK2 can be arranged in sequence in one direction (e.g., the second direction). The first yoke YK1 can generate an attraction force with the first magnet. In addition, the second yoke YK2 can generate an attraction force with the second magnet. Therefore, the posture of the first lens assembly and the second lens assembly can be maintained.

[0231] In addition, the thickness of the first yoke YK1 and the thickness of the second yoke YK2 can vary in some areas. Due to this configuration, the magnetic force generated by the first magnet and the second magnet or the first coil and the second coil can be suppressed from affecting other magnets or coils. For example, the first yoke YK1 can suppress the magnetic force generated by the first magnet from being applied to the second magnet and the second coil.

[0232] Reference Fig.11a , Fig.11b and Fig.11c 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 relative to the 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 substrate portion may be mounted on each of the outer surface of the first side portion 1232a and the outer surface of the second side portion 1232b. The second substrate portion may be positioned outside the drive coil and electrically connected to the drive coil.

[0233] For example, the first substrate portion may be positioned on an outer surface of the first side portion 1232a, and the second substrate portion may be positioned on an outer surface of the second side portion 1232b.

[0234] In addition, first guide grooves GG1a and GG1b in which the first spherical member and the second spherical member are installed may be formed in the inner surface of the first side portion 1232a. The first guide grooves GG1a and GG1b may face the first groove and the second groove. Similarly, second guide grooves GG2a and GG2b in which the first spherical member and the second spherical member are installed may be positioned in the inner surface of the second side portion 1232b. The first guide grooves GG1a and GG1b may face the first groove and the second groove.

[0235] In addition, the first side portion 1232a may include a first side hole 1232ah. The first magnet may be positioned in the first side hole 1232ah. In addition, the length of the first side hole 1232ah may be less than the length of the first coil in the first direction.

[0236] In addition, the second side portion 1232b may include a second side hole 1232bh. The second magnet may be disposed in the second side hole 1232bh. In addition, the length of the second side hole 1232bh may be smaller than the length of the second coil in the first direction.

[0237] In addition, the second-second housing 1232 may include a housing hole 1232h provided in any one of the upper and lower portions thereof. The housing hole 1232h may be used to facilitate coupling, or the first and second lens assemblies may be inspected (eg, visually inspected).

[0238] In addition, the first guide grooves GG1a and GG1b positioned in 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 first guide groove GG1b may have a flat structure. The second guide grooves GG2a and GG2b may be similarly applicable. The first spherical member and the second spherical member are installed in the inclined groove and the flat structure, and thus the first lens assembly or the second lens assembly may move in the optical axis direction.

[0239] Reference Fig.12 and Fig.13 In the camera device according to the present embodiment, an electromagnetic force DEM1 is generated between the first magnet 1252a and the first coil 1251a, and thus the first lens assembly 1222a can move along a track positioned on the inner surface of the shell, in a direction parallel to the optical axis direction, i.e., in a third direction (Z-axis direction) or in a direction opposite to the third direction, using the first spherical member B1 and the second spherical member B2.

[0240] Specifically, in the camera device according to the embodiment, the first magnet 1252a can be provided in the first lens assembly 1222a in a manner such as vertical magnetization. For example, in the embodiment, both the N pole and the S pole of the first magnet 1252a can be positioned to face the first coil 1251a. Therefore, each of the N pole and the S pole of the first magnet 1252a can be provided to correspond to a region in which a current flows in the first coil 1251a in the X-axis direction or in a direction opposite to the X-axis direction.

[0241] In an embodiment, when a magnetic force is applied from the N pole of the first magnet 1252a in a direction opposite to the second direction (Y-axis direction) and a current DE1 flows from the first coil 1251a corresponding to the N pole in a direction opposite to the first direction (X-axis direction), an electromagnetic force DEM1 can be applied along a third direction (Z-axis direction) according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule).

[0242] In addition, in an embodiment, when a magnetic force is applied from the S pole of the first magnet 1252a toward the second direction (Y-axis direction) and current DE1 flows from the first coil 1251a corresponding to the S pole toward the first direction (X-axis direction), an electromagnetic force DEM1 can be applied along the Z-axis direction according to the interaction of electromagnetic forces.

[0243] In this case, since the first coil 1251a is fixed to the side portion of the second housing, the first lens assembly 1222a provided with the first magnet 1252a can be moved 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 be moved in a direction opposite to the direction of the electromagnetic force applied to the second driving coil. In addition, the direction of the electromagnetic force can be changed according to the current of the coil and the magnetic force of the magnet.

[0244] Therefore, the first lens assembly 1222a can move along a track positioned on the inner surface of the housing and in a direction (two directions) parallel to the third direction or the optical axis direction using the first spherical member B1 and the second spherical member B2. In this case, the electromagnetic force DEM1 can be controlled to be proportional to the current DE1 applied to the first coil 1251a.

[0245] 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 installed. 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 installed. The length of each first recess in the first recess RS1 can be preset in the optical axis direction (Z-axis direction). In addition, the length of the second recess RS2 can be preset in the optical axis direction (Z-axis direction). Therefore, the moving distance of each of the first spherical member B1 and the second spherical member B2 in one recess along the optical axis direction can be adjusted. In other words, the first recess RS1 or the second recess RS2 can be a stopper for the first spherical member B1 or the second spherical member B2.

[0246] In addition, in the camera device according to the embodiment, the second magnet 1252b can be provided in the second lens assembly 1222b in a manner such as vertical magnetization or the like. For example, in the embodiment, both the N pole and the S pole of the second magnet 1252b can be positioned to face the second coil 1251b. Therefore, each of the N pole and the S pole of the second magnet 1252b can be provided to correspond to a region where a current flows in the second coil 1251b in the X-axis direction or in a direction opposite to the X-axis direction.

[0247] In an embodiment, when a magnetic force DM2 is applied from the N pole of the second magnet 1252b toward the second direction (Y-axis direction) and a current DE2 flows from the second coil 1251b corresponding to the N pole toward the first direction (X-axis direction), an electromagnetic force DEM2 can be applied along a third direction (Z-axis direction) according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule).

[0248] In addition, in an embodiment, when a magnetic force is applied from the S pole of the second magnet 1252b in a direction opposite to the second direction (Y-axis direction) and a current DE2 flows from the second coil 1251b corresponding to the S pole in a direction opposite to the first direction (X-axis direction), an electromagnetic force DEM2 can be applied along the Z-axis direction according to the interaction of electromagnetic forces.

[0249] In this case, since the second coil 1251b is fixed to the side portion of the second shell, the second lens assembly 1222b on which the second magnet 1252b is disposed can be moved in a direction opposite to the Z-axis direction by the electromagnetic force DEM2 according to the current direction. 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 use the second spherical piece B2 to move along the track positioned on the inner surface of the second shell in a direction parallel to the third direction (Z-axis direction). In this case, the electromagnetic force DEM2 can be controlled to be proportional to the current DE2 applied to the second coil 1251b.

[0250] Reference Fig.14 In the camera device according to the embodiment, the second driving part can provide driving forces F3A, F3B, F4A and F4B for moving the first lens assembly 1222a and the second lens assembly 1222b of the lens part 1220 in the third direction (Z-axis direction). The second driving part may include the second driving coil 1251 and the second driving magnet 1252 as described above. In addition, the lens part 1220 may be moved in the third direction (Z-axis direction) by generating an electromagnetic force between the second driving coil 1251 and the second driving magnet 1252.

[0251] In this case, the first coil 1251a and the second coil 1251b may be disposed in holes formed in side portions (e.g., first side portions and second side portions) of the second housing 1230. In addition, the second coil 1251b may be electrically connected to the first substrate 1271. The first coil 1251a may be electrically connected to the second substrate 1272. Therefore, each of the first coil 1251a and the second coil 1251b may receive a drive signal (e.g., current) from a drive driver on the circuit substrate of the circuit substrate 1300 through the second substrate portion 1270.

[0252] In this case, the first lens assembly 1222a equipped with the first magnet 1252a can be moved along the third direction (Z-axis direction) by the electromagnetic forces F3A and F3B between the first coil 1251a and the first magnet 1252a. In addition, the second lens group 1221b installed on the first lens assembly 1222a can also be moved along the third direction.

[0253] In addition, the second lens assembly 1222b equipped with the second magnet 1252b can be moved along the third direction (Z-axis direction) by the electromagnetic forces F4A and F4B between the second coil 1251b and the second magnet 1252b. In addition, the third lens group 1221c installed on the second lens assembly 1222b can also be moved along the third direction.

[0254] Therefore, as described above, as the second lens group 1221b and the third lens group 1221c move, the focal length or magnification of the optical system can be changed. In an embodiment, as the second lens group 1221b moves, the magnification can be changed. In other words, zooming can be performed. In addition, as the third lens group 1221c moves, the focus can be adjusted. In other words, AF can be performed. Due to this configuration, the second camera actuator can be a fixed zoom actuator or a continuous zoom actuator.

[0255] Fig.15 is a schematic diagram illustrating a circuit substrate according to an embodiment.

[0256] Reference Fig.15 As described above, the circuit substrate 1300 according to the embodiment may include a first circuit substrate portion 1310 and a second circuit substrate portion 1320. The first circuit substrate portion 1310 may be positioned below the base and connected to the base. In addition, the image sensor IS may be disposed on the first circuit substrate portion 1310. In addition, the first circuit substrate portion 1310 and the image sensor IS may be electrically connected. That is, the base may be positioned on the rear end portion of the second camera actuator, and the image sensor and the circuit substrate (first circuit substrate portion) may be positioned on the rear end portion of the base. The base may include a filter (e.g., an infrared filter) and the like.

[0257] In addition, the second circuit substrate portion 1320 can be positioned on the side portion of the base. In particular, the second circuit substrate portion 1320 can be positioned on the first side portion of the base. Therefore, the second circuit substrate portion 1320 can be positioned adjacent to the first coil positioned adjacent to the first side portion, and therefore the electrical connection between them can be easily made. In addition, the second circuit substrate portion 1320 can be positioned in the second side portion of the base. As described above, the second circuit substrate portion 1320 can be set to a plurality of second circuit substrate portions 1320. However, the second circuit substrate portion 1320 is not limited thereto, and may also be arranged only on any one of the first side portion and the second side portion.

[0258] In addition, the circuit substrate 1300 may further include a fixing substrate (not shown) positioned on the side surface. Therefore, even when the circuit substrate 1300 is formed of a flexible material, the rigidity of the circuit substrate 1300 may be maintained by the fixing substrate and the coupling to the base.

[0259] The second circuit substrate portion 1320 of the circuit substrate 1300 may be positioned on a side portion of the second driving portion 1250. The circuit substrate 1300 may be electrically connected to the first driving portion and the second driving portion. For example, such electrical connection may be achieved by surface mounting technology (SMT). However, the present invention is not limited to this method.

[0260] The circuit substrate 1300 may include a circuit board having an electrically connectable wiring pattern, such as a rigid printed circuit board (rigid PCB), a flexible PCB, or a rigid-flexible PCB, etc. However, the present invention is not limited to such types.

[0261] In addition, the circuit substrate 1300 may be electrically connected to another camera module in the terminal or a processor in the terminal. Therefore, the camera actuator and the camera device including the camera actuator may transmit and receive various signals in the terminal.

[0264] In addition, the first lens assembly 1222a may include a first lens holder LAH1 that holds and is connected to the second lens group 1221b, a first track portion RP1, and a second bonding member AM1. The first lens holder LAH1 may be connected 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 identical to and can be used interchangeably with the accommodating portion (e.g., the first accommodating portion or the second accommodating portion) to be described below.

[0265] In addition, the first rail portion RP1 may be positioned at one side of the first lens holder LAH1. In addition, the first bonding member AM1 may be positioned between the first rail portion RP1 and the first lens holder LAH1. The first rail portion RP1 and the first lens holder LAH1 may be coupled using the first bonding member AM1.

[0266] In addition, the first rail portion RP1 may include a side plate on which the spherical portion is mounted and a wing portion extending from the side plate. This will be described below.

In addition, the second lens holder LAH2 may include a second lens hole LH2 for accommodating the third lens group 1221c. That is, at least one lens may be disposed in the second lens hole LH2.

[0268] In addition, the second track portion RP2 may be positioned at the other side portion of the second lens holder LAH2. The first track portion RP1 and the second track portion RP2 may be positioned opposite to each other. For example, the first track portion RP1 and the second track portion RP2 may be positioned to face each other.

[0269] In addition, a second bonding member AM2 may be positioned between the second rail portion RP2 and the second lens holder LAH2. The second rail portion RP2 and the second lens holder LAH2 may be coupled using the second bonding member AM2.

[0270] In addition, the second rail portion RP2 may include a side plate on which the spherical portion is mounted and a wing portion extending from the side plate. This will be described below.

[0271] In addition, at least one of the first lens assembly 1222a and the second lens assembly 1222b may have a structure in which a bonding member is provided between the lens holder and the track portion. Hereinafter, the description will be based on the first lens assembly 1222a. Therefore, the description of the first lens assembly may be equally applicable to the second lens assembly. For example, the description of the first track portion may be equally applicable to the second track portion. In addition, the description of the first bonding member may be equally applicable to the second bonding member. In addition, the description of the first lens holder may be equally applicable to the second lens holder.

[0272] In an embodiment, each of the first lens assembly 1222a and the second lens assembly 1222b may include adjacent outer surfaces. The first lens assembly 1222a may include a first outer surface MM1, and the second lens assembly 1222b may include a second outer surface MM2. The first outer surface MM1 may be the lower surface (or rear surface) of the first lens holder LAH1 based on the optical axis direction (Z-axis direction). In addition, the third outer surface MM3 to be described below may be the upper surface (or front surface) of the first lens holder LAH1. In addition, the second outer surface MM2 may be the upper surface (or front surface) of the second lens holder LAH2, and the fourth outer surface MM4 may be the lower surface (or rear surface) of the second lens holder LAH2.

[0273] In addition, at least a portion of each of the first outer surface MM1 and the second outer surface MM2 may overlap in the optical axis direction (Z axis direction). In an embodiment, at least a portion of each of the first to fourth outer surfaces MM1 to MM4 may overlap in the optical axis direction (Z axis direction).

[0274] 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.

[0275] Fig.17 is a perspective view illustrating a first lens holder, a first rail portion, and a first bonding member in a first lens assembly according to a first embodiment, and Fig.18 is a front view illustrating a first lens holder, a first rail portion, and a first bonding member in the first lens assembly according to the first embodiment. Fig.19 is a top view illustrating a first lens holder, a first rail portion, and a first bonding member in a first lens assembly according to a first embodiment, and Fig. 20 It is a diagram showing the Fig.16 A view of the first lens assembly and the second lens assembly at line II'.

[0276] Reference Figures 17 to 19 , in the first lens assembly 1222a according to the first embodiment, the bonding member AM1 may be positioned between the first lens holder LAH1 and the first rail portion RP1.

[0277] In addition, the first rail portion RP1 may include a side plate RPa positioned at the outermost portion and a wing portion RPb extending from the side plate RPa. The contents to be described below may be similarly applied to the second rail portion RP2.

[0278] The side plate RPa may include the first recess RS1 and the second recess RS2 described above, which are located in the outermost surface. In addition, the first magnet 1252a may be positioned on the side plate RPa. In addition, the first coupling yoke 1254a may be positioned on the side plate RPa. The first magnet 1252a may be positioned on the first coupling yoke 1254a. In addition, the first coupling yoke 1254a may be coupled to the outer surface of the side plate RPa. This coupling may be achieved using one of various coupling members.

[0279] The wing portion RPb may be positioned between the side plate RPa and the first lens holder LAH1 and may be in contact with the side plate RPa. In addition, the first bonding member AM1 is positioned between the first lens holder LAH1 and the first track portion RP1. Therefore, in the first lens assembly 1222a, the wing portion RPb may be in contact with the first bonding member AM1.

[0280] The thickness of the first bonding member AM1 may be constant, or may vary in the optical axis direction (Z-axis direction). For example, active alignment or optical axis arrangement of the first lens holder LAH1 may be performed after the first bonding member AM1 is applied to the first lens holder LAH1. In this case, the first lens holder LAH1 may be tilted at a certain angle θ relative to the optical axis. t1 or θ t2 . In this case, the certain angle can be formed in at least one of the first direction (X-axis direction), the second direction (Y-axis direction) and the third direction (Z-axis direction). That is, the first lens holder LAH1 can be moved in a direction perpendicular to the optical axis, or can be moved along the optical axis. Therefore, the optical axis arrangement of the first lens holder LAH can be carried out more easily. Therefore, as described above, the first bonding member AM1 can vary in the optical axis direction (Z-axis direction). In addition, this can also be similarly applied to other embodiments to be described below. In addition, in other embodiments, the thickness of the first bonding member AM1 can vary in the second direction.

[0281] In addition, in the first lens assembly 1222a according to the first embodiment, the first lens holder LAH1 may include a lens holder surface LAH1S1 in contact with the wing-shaped portion RPb. The lens holder surface LAH1S1 may be an outer surface of the first lens holder LAH1. In addition, the lens holder surface LAH1S1 may be positioned between the first lens holder LAH1 and the first bonding member AM1. Alternatively, the lens holder surface LAH1S1 may be a surface of the first lens holder LAH1 facing the wing-shaped portion RPb.

[0282] The lens holder surface of the first lens holder LAH1 may be changed according to the embodiment. In addition, in the present embodiment, the lens holder surface LAH1S1 of the first lens holder LAH1 may include a convex portion protruding outward and a flat portion. In addition, the area of ​​the convex portion of the lens holder surface LAH1S1 of the first lens holder LAH1 may be larger than the area of ​​the concave portion. That is, the lens holder surface LAH1S1 of the first lens holder LAH1 may have a structure in which the central portion is convex. Due to this configuration, the first lens holder LAH1 can be easily adjusted for active alignment. In other words, even when the first lens holder LAH1 is tilted to a large extent between the first lens holder and the side plate RPa, the first lens holder LAH1 is unlikely to contact the side plate RPa. That is, the first lens holder LAH1 can be connected to the first track portion RP1 in a state in which the first lens holder LAH1 is tilted within an increased range.

[0283] In addition, the first bonding member AM1 may overlap with the first lens holder LAH1, the side plate RPa, and the wing portion RPb in the second direction (Y-axis direction).

[0284] In addition, the first adhesive member AM1 may also overlap the spherical portion and the first and second recesses in the second direction. In addition, the first adhesive member AM1 may also overlap the first magnet 1252a and the first coupling yoke 1254a in the second direction.

[0285] Reference Fig. 20 As described above, the second lens assembly 1222b may be positioned on the rear end portion of the first lens assembly 1222a. In addition, like the first lens assembly 1222a, the second lens assembly 1222b may also include a second lens holder LAH2 and a second track portion RP2. In addition, the second magnet 1252b and the second coupling yoke 1254b may be positioned on the side plate of the second track portion RP2.

[0286] In addition, at least one of the first lens assembly 1222a and the second lens assembly 1222b may include a bonding member AM1 or AM2. For example, each of the first lens assembly 1222a and the second lens assembly 1222b may include a first bonding member AM1 and a second bonding member AM2, respectively. Therefore, active alignment of the first lens holder LAH1 of the first lens assembly 1222a may be performed. In addition, active alignment of the second lens holder LAH2 of the second lens assembly 1222b may also be performed. In addition, the first bonding member AM1 and the second bonding member AM2 may be positioned to correspond to each other relative to the optical axis. For example, the first bonding member AM1 and the second bonding member AM2 may be positioned on different sides relative to the optical axis.

[0290] The wing portion RPb may extend from the side plate RPa in the second direction, and may overlap with the first lens holder LAH1 in the first direction (X-axis direction).

[0291] In addition, the wing portion RPb may be provided above or below the first lens holder LAH1. In the present embodiment, the wing portion RPb may be positioned on the first lens holder LAH1.

[0292] In addition, the first bonding member AM1 may be positioned between the wing portion RPb and the lens holder surface LAH1S2 of the first lens holder LAH1. In the present embodiment, the lens holder surface LAH1S2 of the first lens holder LAH1 may correspond to the upper surface of the first lens holder LAH1.

[0293] In addition, the first bonding member AM1 can overlap with the wing portion RPb and the first lens holder LAH1 in the first direction (X-axis direction). Due to this configuration, the length of the first lens assembly in the second direction (Y-axis direction) is reduced, and thus the camera actuator can be miniaturized in one direction.

[0294] In addition, the thickness of the first bonding member AM1 may vary in the second direction or the third direction. As described above, active alignment or optical axis alignment of the first lens holder LAH1 may be performed after the first bonding member AM1 is applied to the first lens holder LAH1. In this case, when active alignment is performed, the thickness of the first bonding member AM1 may also vary to correspond to the movement of the first lens holder LAH1.

[0295] In addition, in the first rail portion RP1, the side plate RPa and the first lens holder LAH1 may be spaced apart from each other by a predetermined distance gap1 in the second direction.

[0296] Reference Fig. 22In the third embodiment, as described above, the first lens assembly 1222a may include a first lens holder LAH1 that holds and is coupled to the second lens group 1221b, a first track portion RP1, and a first bonding member AM1. In addition, 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.

[0297] In the present embodiment, the first rail portion RP1 may include a side plate RPa and a wing portion RPb extending from the side plate RPa in the second direction.

[0298] The wing portion RPb may extend from the side plate RPa in the second direction, and may overlap with the first lens holder LAH1 in the first direction (X-axis direction).

[0299] In addition, the wing portion RPb may be provided above or below the first lens holder LAH1. In the present embodiment, the wing portion RPb may be positioned below the first lens holder LAH1.

[0300] In addition, the first bonding member AM1 may be positioned between the wing portion RPb and the lens holder surface LAH1S3 of the first lens holder LAH1. In the present embodiment, the lens holder surface LAH1S3 of the first lens holder LAH1 may correspond to the lower surface of the first lens holder LAH1.

[0301] In addition, the first bonding member AM1 can overlap with the wing portion RPb and the first lens holder LAH1 in the first direction (X-axis direction). Due to this configuration, the length of the first lens assembly in the second direction (Y-axis direction) is reduced, and thus the camera actuator can be miniaturized in one direction.

[0302] In addition, the thickness of the first bonding member AM1 may vary in the second direction or the third direction. As described above, active alignment or optical axis alignment of the first lens holder LAH1 may be performed after the first bonding member AM1 is applied to the first lens holder LAH1. In this case, when active alignment is performed, the thickness of the first bonding member AM1 may also vary to correspond to the movement of the first lens holder LAH1.

[0303] In addition, in the first rail portion RP1, the side plate RPa and the first lens holder LAH1 may be spaced apart from each other by a predetermined distance gap2 in the second direction.

[0305] Reference Fig.23 and Fig.24a In the fourth embodiment, as described above, the first lens assembly 1222a may include a first lens holder LAH1 that holds and is coupled to the second lens group 1221b, a first track portion RP1, and a first bonding member AM1. In addition, 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.

[0306] In the present embodiment, the first rail portion RP1 may include a side plate RPa and a wing portion RPb extending from the side plate RPa in the second direction.

[0307] The wing portion RPb may be provided on the front end portion or the rear end portion of the first lens holder LAH1. In the present embodiment, the wing portion RPb may be positioned on the front end portion of the first lens holder LAH1.

In an embodiment, the wing portion RPb may include a wing portion hole RPaH. In addition, the first bonding member AM1 may include a member hole AMH.

[0309] The size of the wing hole RPaH may be different from the size of the member hole AMH. For example, the size of the wing hole RPaH may be larger than the size of the member hole AMH. Therefore, it is possible to suppress the shielding of the light provided to the second lens group 1221b.

[0310] In addition, in the wing-shaped portion RPb, the thickness T1 of each of the upper portion and the lower portion may be different from the thickness T2 of the side portion. For example, the thickness T1 of each of the upper portion and the lower portion may be greater than the thickness T2 of the side portion. The thickness of the first bonding member AM1 may also vary according to the region to correspond to the region.

[0311] In addition, the first bonding member AM1 in the present invention may have a closed loop or an open loop. In the present embodiment, the first bonding member AM1 may have a closed loop. In addition, the first bonding member AM1 may have different thicknesses in each direction according to active alignment.

[0312] In addition, the first bonding member AM1 may be in contact with the third outer surface MM3 of the first lens holder LAH1. In addition, the first bonding member AM1 may overlap with the second lens group 1221b disposed on its front end portion in the second direction. Due to this configuration, the second lens group 1221b may be protected. In addition, in the present invention, the first bonding member may absorb some impact. Therefore, a camera actuator with improved reliability may be provided.

[0313] In addition, the wing-shaped portion RPb, the first bonding member AM1 and the first lens holder LAH1 may overlap in the optical axis direction (Z-axis direction). The first bonding member AM1 may also overlap with the second lens group 1221b in the optical axis direction.

[0314] In addition, in the first rail portion RP1, the side plate RPa and the first lens holder LAH1 may be spaced apart from each other by a predetermined distance gap3 in the second direction.

[0315] Reference Figure 24b In the first lens assembly according to the modified embodiment, the first bonding member AM1 may have a disconnected loop. Therefore, when active alignment is performed, the first lens holder LAH1 may be easily tilted.

[0316] Otherwise, the above applies.

[0317] Fig.25 is a top view illustrating a first lens holder, a first rail portion, and a first bonding member in a first lens assembly according to a fifth embodiment, and Fig.26 is a rear view illustrating the first lens holder, the first rail portion, and the first bonding member in the first lens assembly according to the fifth embodiment.

[0318] Reference Fig.25 and Fig.26In the fifth embodiment, as described above, the first lens assembly 1222a may include a first lens holder LAH1 that holds and is coupled to the second lens group 1221b, a first track portion RP1, and a first bonding member AM1. In addition, 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.

[0319] In the present embodiment, the first rail portion RP1 may include a side plate RPa and a wing portion RPb extending from the side plate RPa in the second direction.

[0320] The wing portion RPb may be provided on the front end portion or the rear end portion of the first lens holder LAH1. In the present embodiment, the wing portion RPb may be positioned behind the first lens holder LAH1.

[0321] That is, each of the wing portion RPb and the first bonding member AM1 may include a hole so that light passing through the second lens group 1221b is provided to the rear end portion without being blocked. In an embodiment, the wing portion RPb may include a wing portion hole RPaH. In addition, the first bonding member AM1 may include a member hole AMH.

[0322] The size of the wing hole RPaH may be different from the size of the member hole AMH. For example, the size of the wing hole RPaH may be larger than the size of the member hole AMH. Therefore, it is possible to suppress the shielding of the light provided to the second lens group 1221b.

[0323] In addition, in the wing-shaped portion RPb, the thickness T3 of each of the upper portion and the lower portion may be different from the thickness T4 of the side portion. For example, the thickness T3 of each of the upper portion and the lower portion may be less than the thickness T4 of the side portion. Therefore, the separation of the second lens group 1221b can be suppressed. In addition, the thickness of the first bonding member AM1 may also vary according to the region to correspond to the region.

[0324] In addition, in the present invention, the first bonding member AM1 may have a closed loop or an open loop. In the present embodiment, the first bonding member AM1 may have a closed loop. In addition, the first bonding member AM1 may have different thicknesses in each direction according to active alignment.
