Description

Technical Field

[0001] The present invention relates to a camera actuator and a camera module including the camera actuator. Background Technology

[0002] A camera is a device used to take photos or videos of a subject and is mounted on portable devices, drones, vehicles, etc. Camera modules may have image stabilization (IS) functions to correct or prevent image shake caused by user movement to improve image quality, autofocus functions to align the focal length of the lens by automatically adjusting the distance between the image sensor and the lens, and zoom functions to capture remote subjects by increasing or decreasing the magnification of remote subjects through zoom lenses.

[0003] Meanwhile, the more pixels an image sensor has, the higher the resolution and the smaller the size of each pixel. However, smaller pixels receive less light in the same amount of time. Therefore, as the number of camera pixels increases, image shake caused by hand tremors when slowing down the shutter speed in dark environments may become more severe. A representative image stabilization (IS) technology is the optical image stabilizer (OIS) technique, which corrects motion by altering the light path.

[0004] According to general OIS technology, camera motion can be detected by gyroscope sensors, and the lens can be tilted or moved according to the detected motion, or the camera module including the lens and image sensor can be tilted or moved. When the lens or the camera module including the lens and image sensor is tilted or moved to achieve OIS, it is necessary to additionally ensure the space around the lens or camera module for tilting or moving.

[0005] Meanwhile, the actuators for OIS can be positioned around the lens. In this case, the actuators for OIS may include actuators responsible for tilting around two axes perpendicular to the Z-axis (which is the optical axis), namely, an actuator responsible for tilting along the X-axis and an actuator responsible for tilting along the Y-axis.

[0006] However, due to the need for ultra-thin and ultra-small camera modules, there are significant space constraints in setting up actuators for OIS, and it may be difficult to ensure sufficient space in which the lens, or the camera module itself including the lens and image sensor, can be tilted or moved to achieve OIS. Furthermore, as the number of pixels in the camera increases, it is preferable to increase the size of the lens to increase the amount of light received; however, the space occupied by the actuators for OIS may limit the ability to increase the size of the lens.

[0007] Furthermore, when zoom, AF, and OIS functions are all included in a camera module, there is a problem of magnetic field interference caused by the OIS magnet and the AF or zoom magnet being set close to each other.

[0008] In addition, there are issues such as differences in torque due to different postures and the need to improve energy efficiency. Summary of the Invention

[0116] Figure 1 This is a perspective view of the camera module according to an embodiment. Figure 2 This is an exploded perspective view of the camera module according to an embodiment. Figure 3 It is along Figure 1 The sectional view taken by line A-A' in the middle.

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

[0118] The cover CV can cover the first camera actuator 1100 and the second camera actuator 1200. The bonding force between the first camera actuator 1100 and the second camera actuator 1200 can be increased by the cover CV.

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

[0120] Furthermore, the first camera actuator 1100 may be an optical image stabilizer (OIS) actuator. For example, the first camera actuator 1100 may move optical components in a direction perpendicular to the optical axis.

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

[0122] The first camera actuator 1100 can alter the optical path. In an embodiment, the first camera actuator 1100 can vertically alter the optical path via internal optical components (e.g., prisms or mirrors). With this configuration, even when the thickness of the mobile terminal is reduced, a lens with a greater thickness than the mobile terminal can be configured by altering the optical path, thus enabling magnification and autofocus (AF) and OIS functions.

[0123] However, the present invention is not limited thereto, and the first camera actuator 1100 can change the optical path vertically or at a predetermined angle multiple times.

[0124] The second camera actuator 1200 can be located at the rear end of the first camera actuator 1100. The second camera actuator 1200 can be coupled to the first camera actuator 1100. In addition, they can be coupled to each other in various ways.

[0125] Furthermore, the second camera actuator 1200 can be a zoom actuator or an AF actuator. For example, the second camera actuator 1200 can support one or more lenses and perform AF or zoom functions by moving the lenses according to predetermined control signals from the control unit.

[0126] In addition, one or more lenses can move independently or individually along the optical axis.

[0127] Circuit board 1300 may be disposed on the rear end of the second camera actuator 1200. Circuit board 1300 may be electrically connected to the second camera actuator 1200 and the first camera actuator 1100. Furthermore, multiple circuit boards 1300 may be present. Circuit board 1300 may include an image sensor, etc., and may include a connector for electrical connection to a processor of another external camera module or terminal.

[0128] The camera module according to the embodiments can be formed as a single camera module or multiple camera modules. For example, multiple camera modules may include a first camera module and a second camera module. Furthermore, in this invention, the camera module may be referred to as a "camera device," "camera equipment," "camera assembly," "imaging device," "imaging unit," "imaging apparatus," "imaging module," etc. Additionally, the camera actuators (e.g., a first camera actuator and a second camera actuator) described below are components for moving (or rotating) a lens or optical component, and may or may not include a lens or optical component. The following description will be based on the concept that the camera actuator includes a lens or optical component. Furthermore, the concepts of "lens driving device," "lens unit," "driving device," "driving unit," etc., can also be used as concepts including a camera actuator and a lens (or optical component).

[0129] Furthermore, the first camera module may include a single actuator or multiple actuators. For example, the first camera module may include a first camera actuator 1100 and a second camera actuator 1200.

[0130] Furthermore, the second camera module may include an actuator (not shown) disposed in a predetermined housing (not shown) and capable of driving the lens section. The actuator may be a voice coil motor, a micro-actuator, a silicon actuator, etc., and can be applied to various methods, such as electrostatic, thermal, dual-mode, and electrostatic force methods, but the present invention is not limited thereto. Additionally, in the specification, the camera actuator may be referred to as an actuator, etc. Furthermore, a camera module composed of multiple camera modules can be installed in various electronic devices, such as mobile terminals.

[0131] refer to Figure 3 According to the embodiments, the camera module may include a first camera actuator 1100 for performing OIS functions and a second camera actuator 1200 for performing zoom and AF functions.

[0132] Light can enter the camera module or the first camera actuator through an opening in the upper surface of the first camera actuator 1100. In other words, light can enter the first camera actuator 1100 along the optical axis (e.g., the X-axis) and its path can be altered by optical components in the vertical axis direction (e.g., the Z-axis). Furthermore, light can pass through the second camera actuator 1200 and can enter the image sensor IS (PATH) located at one end of the second camera actuator 1200.

[0133] In this specification, the bottom surface refers to one side in the first direction. Furthermore, the first direction is the X-axis direction in the figure, and can be interchanged with the second axis direction, etc. The second direction is the Y-axis direction in the figure, and can be interchanged with the first axis direction. The second direction is perpendicular to the first direction. Furthermore, the third direction is the Z-axis direction in the figure, and can be interchanged with the third axis direction. Furthermore, the third direction is perpendicular to both the first and second directions. Here, the third direction (Z-axis direction) corresponds to the optical axis direction, while the first direction (X-axis direction) and the second direction (Y-axis direction) are directions perpendicular to the optical axis and can be tilted by the second camera actuator. Furthermore, in the following description of the first camera actuator 1100 and the second camera actuator 1200, the optical axis direction is the third direction (Z-axis direction), and the following description will be based on this.

[0134] Furthermore, in the specification, the inner side can be the direction from the cover CV toward the first camera actuator, and the outer side can be the opposite direction to the inner side. In other words, the first camera actuator and the second camera actuator can be located inside the cover CV, and the cover CV can be located outside the first camera actuator or the second camera actuator.

[0135] Furthermore, with this configuration, the camera module according to the embodiment can overcome the spatial limitations of the first and second camera actuators by changing the optical path. In other words, the camera module according to the embodiment can minimize the thickness of the camera module while extending the optical path in response to changes in the optical path. Furthermore, it should be understood that the second camera actuator can also provide a wide range of magnification by controlling the focus, etc., in the extended optical path.

[0136] Furthermore, the camera module according to the embodiment can achieve OIS by controlling the optical path with a first camera actuator, thereby minimizing the occurrence of eccentricity or tilt and providing optimal optical characteristics.

[0137] Furthermore, the second camera actuator 1200 may include an optical system and a lens drive unit. For example, the second camera actuator 1200 may include one or more of a first lens assembly, a second lens assembly, a third lens assembly, and a guide pin.

[0138] In addition, the second camera actuator 1200 may include a coil and a magnet, and perform high-magnification zoom function.

[0139] For example, the first and second lens assemblies can be movable lenses that move via coils, magnets, and guide pins, while the third lens assembly can be a fixed lens; however, the invention is not limited to these. For instance, the third lens assembly can function as a focuser, through which light forms an image at a specific location, while the first lens assembly can function as a zoomor, used to re-form the image formed by the third lens assembly (i.e., the focuser) at another location. Simultaneously, the first lens assembly can be in a state of large magnification variation because the distance to the subject or the image distance changes significantly, and the first lens assembly (i.e., the zoomor) can play a crucial role in the focal length or magnification variation of the optical system. Furthermore, the imaging point of the image formed by the first lens assembly (i.e., the zoomor) may vary slightly depending on the location. Therefore, the second lens assembly can perform a position compensation function for the image formed by the zoomor. For example, the second lens assembly can function as a compensator to accurately form an image at the actual location of the image sensor using the imaging point of the image formed by the first lens assembly as a variable. For example, the first and second lens assemblies can be driven by electromagnetic forces generated by the interaction between the coil and the magnet. The above description applies to the lens assembly described below. Furthermore, the first to third lens assemblies can move upwards along the optical axis, i.e., upwards along the third axis. Additionally, the first to third lens assemblies can move upwards along the third axis independently or dependently on each other.

[0140] Furthermore, when the OIS actuator and the AF or zoom actuator are configured according to embodiments of the present invention, magnetic field interference with the AF magnet or zoom magnet can be prevented during OIS operation. Since the first driving magnet of the first camera actuator 1100 is separately disposed 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 can be used interchangeably with terms such as hand shake correction, optical image stabilization, optical image correction, and shake correction.

[0141] Figure 4 This is a perspective view of the first camera actuator according to an embodiment, and Figure 5 This is an exploded perspective view of the first camera actuator according to an embodiment.

[0142] refer to Figure 4 and Figure 5 According to an embodiment, the first camera actuator 1100 includes a first housing 1120, a mover 1130, a rotating part 1140, a first driving part 1150, and a fastening member 1131a.

[0143] The mover 1130 may include a retainer 1131 and an optical component 1132 disposed on the retainer 1131. In addition, the mover 1130 may also include the fastening component 1131a described above, and may be coupled with the fastening component 1131a to rotate integrally.

[0144] In addition, the rotating part 1140 may include a tilting guide part 1141 and a first magnetic body 1142 and a second magnetic body 1143 with different polarities to press the tilting guide part 1141.

[0145] In addition, the first drive unit 1150 includes a first drive magnet 1151, a first drive coil 1152, a Hall sensor unit 1153, a first plate unit 1154, and a yoke unit 1155.

[0146] First, the first camera actuator 1100 may include a shield (not shown). The shield (not shown) may be located on the outermost side of the first camera actuator 1100 and positioned around the rotating part 1140 and the first drive part 1150, as will be described below.

[0147] The shield (not shown) can block or reduce electromagnetic waves generated from the outside. In other words, the shield (not shown) can reduce the occurrence of malfunctions in the rotating part 1140 or the first drive part 1150.

[0148] The first housing 1120 may be located inside the shield (not shown). When there is no shield, the first housing 1120 may be located on the outermost side of the first camera actuator.

[0149] Furthermore, the first housing 1120 may be located inside the first plate portion 1154, which will be described below. The first housing 1120 may be fastened by fitting to or mating with a shield (not shown).

[0150] The first housing 1120 may include a first housing side 1121, a second housing side 1122, a third housing side 1123, a fourth housing side 1124, and a fifth housing side 1126. These will be described in detail below.

[0151] In particular, the fifth housing side portion 1126 may be integrally formed with the first housing 1120 or separately formed from the first housing 1120. In this specification, the following description will be given based on the premise that the fifth housing side portion 1126 and the first housing 1120 are integrally formed. Furthermore, a fastening member 1131a may pass through the fifth housing side portion 1126. Its description will be given below.

[0152] The mover 1130 includes a retainer 1131 and an optical component 1132 disposed on the retainer 1131.

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

[0154] Furthermore, the retainer 1131 may include a fastening member 1131a disposed in the fourth mounting recess. A detailed description thereof will be given below.

[0155] Optical component 1132 can be mounted on holder 1131. For this purpose, holder 1131 can have a mounting surface, and the mounting surface can be formed by a receiving groove. In embodiments, optical component 1132 can be formed as a mirror or prism. Although described below based on a prism, optical component 1132 can also consist of multiple lenses as in the embodiments described above. Alternatively, optical component 1132 can consist of multiple lenses and prisms or mirrors. Furthermore, optical component 1132 may include a reflector disposed therein. However, the invention is not limited thereto.

[0156] Furthermore, optical component 1132 can reflect light reflected from the outside (e.g., the subject) into the camera module. In other words, optical component 1132 can overcome the spatial limitations of the first and second camera actuators by altering the optical path of the reflected light. As described above, it should be understood that the camera module can also provide a wide range of magnifications by minimizing thickness while extending the optical path.

[0157] The fastening member 1131a can be coupled to the retainer 1131. The fastening member 1131a can be disposed on the outside of the retainer 1131, and at least a portion of the fastening member 1131a can be disposed on the inside of the housing. Furthermore, the fastening member 1131a can be disposed in a groove other than the fourth mounting groove in a region located on the fourth outer surface of the retainer 1131. In this case, the fastening member 1131a and the retainer 1131 can be joined by an adhesive member. For example, the adhesive member can be made of a material such as epoxy resin. Therefore, the fastening member 1131a can be joined to the retainer 1131, and at least a portion of the fifth housing side 1126 can be located between the fastening member 1131a and the retainer 1131. For example, at least a portion of the fifth housing side 1126 can pass through the space formed between the fastening member 1131a and the retainer 1131.

[0158] Furthermore, the fastening member 1131a can be formed in a structure separate from the retainer 1131. With this configuration, the first camera actuator can be easily assembled, as will be described below. Alternatively, the fastening member 1131a can be formed integrally with the retainer 1131, but will be described below as having a separate structure.

[0159] The rotating part 1140 includes a tilting guide part 1141 and a first magnetic body 1142 and a second magnetic body 1143 with different polarities to press the tilting guide part 1141.

[0160] The tilting guide portion 1141 can be coupled to the aforementioned mover 1130 and first housing 1120. Specifically, the tilting guide portion 1141 can be disposed between the retainer 1131 and the fifth housing side portion 1126. Therefore, the tilting guide portion 1141 can be coupled to the mover 1130 of the retainer 1131 and the first housing 1120. However, unlike the above description, in this embodiment, the tilting guide portion 1141 can be disposed between the fifth housing side portion 1126 and the retainer 1131. Specifically, the tilting guide portion 1141 can be disposed between the fifth housing side portion 1126 and the fourth mounting groove of the retainer 1131.

[0161] The fastening member 1131a, the fifth housing side portion 1126, the tilting guide portion 1141, and the retainer 1131 can be sequentially arranged in the third third direction (Z-axis direction) (relative to the outermost side). Furthermore, the first magnetic body 1142 and the second magnetic body 1143 are respectively disposed in the first groove gr1 formed in the fastening member 1131a and the second groove gr2 formed in the fifth housing side portion 1126. In this embodiment, the first groove gr1 and the second groove gr2 may have different positions than those described in the other embodiment above. However, the first groove gr1 is located in the fastening member 1131a and moves integrally with the retainer, while the second groove gr2 is located in the fifth housing side portion 1126 corresponding to the first groove gr1 and engages with the first housing 1120. Therefore, these terms will be used interchangeably. Furthermore, the second groove gr2 can be located between the first groove gr1 and the tilting guide portion 1141.

[0162] Furthermore, the tilt guide 1141 can be disposed adjacent to the optical axis. Therefore, the actuator according to this embodiment can easily change the optical path according to the tilt of the first axis and the tilt of the second axis, as will be described below.

[0163] The tilting guide 1141 may include a first protrusion spaced apart from each other in a first direction (X-axis direction) and a second protrusion spaced apart from each other in a second direction (Y-axis direction). Furthermore, the first and second protrusions may protrude in opposite directions. A detailed description will follow.

[0164] Furthermore, as described above, the first magnetic body 1142 may be located in the fastening member 1131a. Furthermore, the second magnetic body 1143 may be located in the fifth housing side portion 1126.

[0165] The first magnetic body 1142 and the second magnetic body 1143 can have the same polarity. For example, the first magnetic body 1142 can be a magnet with an N pole, and the second magnetic body 1143 can be a magnet with an N pole. Alternatively, the first magnetic body 1142 can be a magnet with an S pole, and the second magnetic body 1143 can be a magnet with an S pole.

[0166] For example, the second pole surface of the second magnetic body 1143 and the first pole surface of the first magnetic body 1142 facing the second pole surface can have the same polarity. In other words, the first magnetic body 1142 and the second magnetic body 1143 can generate a force that pushes each other, and for this purpose, they can have various materials, functions, etc.

[0167] For example, the first magnetic body 1142 and the second magnetic body 1143 can generate a repulsive force between them due to the aforementioned polarity. With this configuration, the repulsive force can be applied to the fastening member 1131a or retainer 1131 coupled to the first magnetic body 1142, and to the fifth housing side 1126 or first housing 1120 coupled to the second magnetic body 1143. At this time, the repulsive force applied to the fastening member 1131a can be transmitted to the retainer 1131 coupled to the fastening member 1131a. Therefore, the inclined guide portion 1141 provided between the fastening member 1131a and the fifth housing side 1126 can be tightly pressed by the repulsive force. In other words, this repulsive force can maintain the position of the inclined guide portion 1141 between the retainer 1131 and the first housing 1120 (or the fifth housing side 1126). With this configuration, the position between the mover 1130 and the first housing 1120 can be maintained even when the X-axis or Y-axis is tilted. Furthermore, through the repulsive force between the second magnetic body 1143 and the first magnetic body 1142, the tilting guide portion can make close contact with the fifth housing side portion 1126 and the retainer 1131.

[0168] The first drive unit 1150 includes a first drive magnet 1151, a first drive coil 1152, a Hall sensor unit 1153, a first plate unit 1154, and a yoke unit 1155. These will be described below.

[0169] Figure 6a This is a perspective view of the first housing of the first camera actuator according to an embodiment. Figure 6b Is with Figure 6a Perspective views in different directions, and Figure 6cThis is a front view of the first housing of the first camera actuator according to an embodiment.

[0170] refer to Figures 6a to 6c According to this embodiment, the first housing 1120 may include a first housing side portion 1121 to a fifth housing side portion 1126. The first housing side portion 1121 and the second housing side portion 1122 may be configured to face each other. Furthermore, the third housing side portion 1123 and the fourth housing side portion 1124 may be configured to face each other.

[0171] Furthermore, the third housing side 1123 and the fourth housing side 1124 may be disposed between the first housing side 1121 and the second housing side 1122.

[0172] The third housing side 1123 and the fourth housing side 1124 can contact the first housing side 1121, the second housing side 1122, and the fourth housing side 1124. Furthermore, the third housing side 1123 can be the bottom surface of the first housing 1120. Furthermore, the fourth housing side 1124 can be the upper surface of the first housing 1120. Moreover, the above description can also be applied to descriptions of orientation in the same manner.

[0173] Furthermore, the first housing side portion 1121 may include a first housing hole 1121a. A first coil, which will be described below, may be located in the first housing hole 1121a.

[0174] Furthermore, the second housing side portion 1122 may include a second housing hole 1122a. Additionally, the second coil, as described below, may be located within the second housing hole 1122a.

[0175] Furthermore, the first housing side 1121 and the second housing side 1122 can be the side surfaces of the first housing 1120.

[0176] The first and second coils can be coupled to the first plate. In one embodiment, the first and second coils can be electrically connected to the first plate to allow current to flow. This current is an element of electromagnetic force, through which the second camera actuator can tilt relative to the X-axis.

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

[0178] The third coil, as described below, can be disposed in the third housing hole 1123a. Furthermore, the third coil can be electrically connected to the first plate portion that contacts the first housing 1120, and the third coil and the first plate portion can be coupled together. Therefore, the third coil can be electrically connected to the first plate portion to receive current from the first plate portion. This current is an element of electromagnetic force, by which the second camera actuator can tilt relative to the Y-axis.

[0179] The fifth housing side portion 1126 can be disposed between the first housing side portion 1121 and the fourth housing side portion 1124. Therefore, the fifth housing side portion 1126 can be located above the third housing side portion 1123. For example, the fifth housing side portion 1126 can be located on one side. The fifth housing side portion 1126 and the retainer can be sequentially positioned relative to a third direction.

[0180] The fourth housing side 1124 can be disposed between the first housing side 1121 and the second housing side 1122, and can contact the first housing side 1121, the second housing side 1122 and the third housing side 1123.

[0181] Furthermore, the fourth housing side portion 1124 may include a fourth housing aperture 1124a. The fourth housing aperture 1124a may be located above the optical component. Therefore, light can pass through the fourth housing aperture 1124a and can be incident on the optical component.

[0182] Furthermore, the first housing 1120 may include a receiving portion 1125 formed by the first housing side portion 1121 to the fifth housing side portion 1126. Fastening members, tilting guides, movers, etc., may be located as components in the receiving portion 1125.

[0183] In one embodiment, the fifth housing side 1126 may be located between the first housing side 1121 and the second housing side 1122. Furthermore, the fifth housing side 1126 may be located between the third housing side 1123 and the fourth housing side 1124.

[0184] Furthermore, the fifth housing side 1126 may be located above the third housing side 1123 and may contact the first housing side to the third housing side.

[0185] Furthermore, the fifth housing side portion 1126 includes a second receiving groove, in which a second protrusion of the tilting guide is disposed. The second receiving groove PH2 may be located in the inner surface 1126s1 of the fifth housing side portion 1126. The inner surface 1126s1 of the fifth housing side portion 1126 may protrude inward between the through holes 1126a and 1126b of the fifth housing side portion 1126. Therefore, in the fifth housing side portion 1126, the protrusion of the tilting guide (e.g., the second protrusion) is arranged adjacent to the prism in the fourth receiving groove so that the protrusion, serving as the tilting reference axis, is positioned close to the center of gravity of the mover 1130. Therefore, when the retainer tilts, the torque required to move the mover 1130 to tilt can be minimized. Therefore, the current consumption for the drive coil can also be minimized, thereby reducing the power consumption of the camera actuator.

[0186] Furthermore, the fifth housing side portion 1126 may include through holes 1126a and 1126b. Multiple through holes may exist, and the housing may consist of a first through hole 1126a and a second through hole 1126b.

[0187] The first and second extensions of the fastening member, described below, can pass through the first through hole 1126a and the second through hole 1126b, respectively. Therefore, the fastening member and the fifth housing side can be joined. In other words, the first housing and the mover can be joined together.

[0188] The second receiving groove PH2 can be located between the first through hole 1126a and the second through hole 1126b. With this configuration, the bonding force between the tilt guide 1141 and the fifth housing side 1126 can be improved, thereby preventing the reduction in tilting accuracy caused by the movement of the tilt guide 1141 in the first housing.

[0189] Furthermore, the second groove gr2 can be located in the outer surface 1126s2 of the fifth housing side portion 1126. A second magnetic body can be disposed in the second groove gr2. Furthermore, the outer surface 1126s2 of the fifth housing side portion 1126 can face the inner surface of the fastening member or the member base portion. Furthermore, the first magnetic body disposed on the fastening member and the second magnetic body of the fifth housing side portion 1126 can face each other and generate the aforementioned repulsive force. Therefore, since the fifth housing side portion 1126 presses the tilting guide inward or presses the retainer by the repulsive force, even when current is injected into the coil, the mover can be separated from the third housing side portion in the first housing by a predetermined distance. In other words, the bonding force between the mover, the housing, and the tilting guide portion can be maintained.

[0190] Furthermore, multiple additional grooves may exist in the outer surface 1126s2 of the fifth housing side 1126. This is to facilitate the manufacturing of the first housing in the process.

[0191] Furthermore, when the fifth housing side portion 1126 is integrally formed with the first housing 1120, the bonding force between the fifth housing side portion 1126 and the first housing 1120 can be improved, thereby enhancing the reliability of the camera actuator. Additionally, when the fifth housing side portion 1126 and the first housing 1120 are formed separately, the ease of assembly and manufacturing of the fifth housing side portion 1126 and the first housing 1120 can be improved.

[0192] Furthermore, in an embodiment, the fifth housing side portion 1126 may include a first through hole 1126a and a second through hole 1126b. Additionally, the first through hole 1126a and the second through hole 1126b may be arranged side-by-side in a second direction (Y-axis direction) to overlap each other.

[0193] Furthermore, the fifth housing side portion 1126 may include an upper member UA located above the first through hole 1126a and the second through hole 1126b, and a lower member BA located below the first through hole 1126a and the second through hole 1126b. Therefore, the first through hole 1126a and the second through hole 1126b may be located at the center of the fifth housing side portion 1126. In other words, the fifth housing side portion 1126 may include a connecting member MA located in the side portion of the first through hole 1126a and the second through hole 1126b. In other words, the upper member UA and the lower member BA can be connected to each other via the connecting member MA. Furthermore, multiple lower members BA may exist to form the first and second through holes, and the multiple lower members BA are spaced apart from each other in a second direction (Y-axis direction).

[0194] Therefore, the fifth housing side portion 1126 can have an upper member UA, thereby increasing rigidity. For example, the rigidity of the fifth housing side portion 1126 can be increased compared to the case where the upper member UA is not present. For example, in this embodiment, the rigidity may be N / μm. Therefore, the reliability of the first camera actuator according to the embodiment can be improved.

[0195] Furthermore, the fifth housing side 1126 may further include a first protrusion and a second protrusion. The first protrusion may contact the first housing side, and the second protrusion may contact the second housing side. The first protrusion may extend from one end of the outer surface 1126s2 of the fifth housing side in a third direction (Z-axis direction). The second protrusion may extend from the other end of the outer surface 1126s2 of the fifth housing side in a third direction (Z-axis direction). In other words, the first and second protrusions may extend toward the retainer.

[0196] Furthermore, the fifth housing side portion 1126 may have an internal thickness Id1 greater than the external thickness Id2. The thickness can be the length in the third direction (Z-axis direction). With this configuration, damage to the fifth housing side portion 1126 can be suppressed even when the second protrusion of the tilting guide is placed in the second receiving groove PH2 formed in the inner surface 1126s1 of the fifth housing side portion 1126. In other words, the reliability of the camera actuator can be improved.

[0197] Figure 7 This is a perspective view of the optical components of the first camera actuator according to an embodiment.

[0198] The optical component 1132 can be mounted on the holder. The optical component 1132 can be a right-angle prism that serves as a reflector, but the invention is not limited thereto.

[0199] In one embodiment, the optical component 1132 may have a protrusion (not shown) on a portion of its outer surface. The optical component 1132 can be easily coupled to the retainer via the protrusion (not shown). Alternatively, the retainer may have a groove or a protrusion, which can also be coupled to the optical component 1132.

[0200] Furthermore, the bottom surface 1132b of the optical component 1132 can be disposed on the mounting surface of the retainer. Therefore, the bottom surface 1132b of the optical component 1132 can correspond to the mounting surface of the retainer. In an embodiment, the bottom surface 1132b can be formed as an inclined surface, similar to the mounting surface of the retainer. Therefore, the prism moves according to the movement of the retainer, while preventing the optical component 1132 from separating from the retainer due to movement.

[0201] Furthermore, a groove can be formed in the bottom surface 1132b of the optical component 1132, and an adhesive member can be applied so that the optical component 1132 can be bonded to the retainer. Alternatively, an adhesive member can be applied to the groove or protrusion of the retainer, and thus the retainer can also be bonded to the optical component 1132.

[0202] Furthermore, as described above, the optical component 1132 can be configured to reflect light reflected from the outside (e.g., an object) back to the camera module. As in the embodiment, the optical component 1132 can also be configured as a single mirror. Furthermore, the optical component 1132 can overcome the spatial limitations of the first and second camera actuators by altering the optical path of the reflected light. As described above, it should be understood that the camera module can also provide a wide range of magnifications by minimizing its thickness while extending the optical path. Furthermore, it should be understood that the camera actuator including the camera module according to the embodiment can also provide a wide range of magnifications by minimizing its thickness while extending the optical path.

[0203] Figure 8a This is a perspective view of the holder of the first camera actuator according to an embodiment. Figure 8b This is a bottom view of the holder of the first camera actuator according to an embodiment. Figure 8c This is a front view of the holder of the first camera actuator according to an embodiment. Figure 8d This is a rear view of the fastening member of the first camera actuator according to an embodiment, and Figure 8e This is a bottom view of the fastening member of the first camera actuator according to an embodiment.

[0204] refer to Figures 8a to 8eThe retainer 1131 may include a mounting surface 1131k on which the optical component 1132 is mounted. The mounting surface 1131k may be an inclined surface. In addition, the retainer 1131 may include a jaw portion on the upper part of the mounting surface 1131k. Furthermore, the jaw portion of the retainer 1131 may engage with a protrusion (not shown) of the optical component 1132.

[0205] The retainer 1131 may include multiple outer surfaces. For example, the retainer 1131 may include a first retainer outer surface 1131S1, a second retainer outer surface 1131S2, a third retainer outer surface 1131S3, and a fourth retainer outer surface 1131S4.

[0206] The outer surface 1131S1 of the first retainer can be positioned to face the outer surface 1131S2 of the second retainer. In other words, the outer surface 1131S1 of the first retainer can be symmetrically arranged with respect to the outer surface 1131S2 of the second retainer with respect to the first direction (X-axis direction).

[0207] The outer surface 1131S1 of the first retainer can be positioned to correspond to the side of the first housing. In other words, the outer surface 1131S1 of the first retainer can be positioned to face the side of the first housing. Furthermore, the outer surface 1131S2 of the second retainer can be positioned to correspond to the side of the second housing. In other words, the outer surface 1131S2 of the second retainer can be positioned to face the side of the second housing.

[0208] Furthermore, the outer surface 1131S1 of the first retainer may include a first mounting groove 1131S1a. Furthermore, the outer surface 1131S2 of the second retainer may include a second mounting groove 1131S2a. The first mounting groove 1131S1a and the second mounting groove 1131S2a may be symmetrically arranged with respect to the first direction (X-axis direction).

[0209] Furthermore, the first mounting groove 1131S1a and the second mounting groove 1131S2a can be configured to overlap in the second direction (Y-axis direction). Additionally, the first magnet 1151a can be disposed in the first mounting groove 1131S1a, and the second magnet 1151b can be disposed in the second mounting groove 1131S2a. The first magnet 1151a and the second magnet 1151b can also be symmetrically arranged relative to the first direction (X-axis direction). It should be understood from the specification that the first to third magnets can be joined to the housing via a yoke or adhesive member.

[0210] As described above, due to the positions of the first and second mounting grooves, as well as the first and second magnets, the electromagnetic force generated by each magnet can be coaxially provided to the first retainer outer surface S1131S1 and the second retainer outer surface S1131S2. For example, the region of the first retainer outer surface S1131S1 to which the electromagnetic force is applied (e.g., the portion with the strongest electromagnetic force) and the region of the second retainer outer surface S1131S2 to which the electromagnetic force is applied (e.g., the portion with the strongest electromagnetic force) can be located on an axis parallel to the second direction (Y-axis direction). Therefore, X-axis tilting can be performed accurately.

[0211] The first magnet 1151a can be disposed in the first mounting groove 1131S1a, and the second magnet 1151b can be disposed in the second mounting groove 1131S2a.

[0212] The third retainer outer surface 1131S3 may be an outer surface that contacts the first retainer outer surface 1131S1 and the second retainer outer surface 1131S2 and extends in a second direction (Y-axis direction) from one side of each of the first retainer outer surfaces 1131S1 and the second retainer outer surface 1131S2. Furthermore, the third retainer outer surface 1131S3 may be located between the first retainer outer surface 1131S1 and the second retainer outer surface 1131S2. The third retainer outer surface 1131S3 may be the bottom surface of the retainer 1131. In other words, the third retainer outer surface 1131S3 may be positioned facing the side of the third housing.

[0213] Furthermore, the outer surface 1131S3 of the third retainer may include a third mounting groove 1131S3a. The third magnet 1151c may be disposed in the third mounting groove 1131S3a. The outer surface 1131S3 of the third retainer may be positioned facing the side portion 1123 of the third housing.

[0214] Furthermore, the third housing hole 1123a can at least partially overlap with the third mounting groove 1131S3a in the first direction (X-axis direction). Therefore, the third magnet 1151c in the third mounting groove 1131S3a and the third coil 1152c in the third housing hole 1123a can be positioned facing each other. Moreover, the third magnet 1151c and the third coil 1152c generate electromagnetic force, enabling the second camera actuator to perform Y-axis tilting.

[0215] Furthermore, X-axis tilt can be achieved by multiple magnets (first magnet 1151a and second magnet 1151b), while Y-axis tilt can be achieved by only the third magnet 1151c.

[0216] In an embodiment, the third mounting groove 1131S3a may have a wider width than the first mounting groove 1131S1a or the second mounting groove 1131S2a. With this configuration, Y-axis tilting can be performed via current control similar to X-axis tilting.

[0217] Furthermore, at least one of the first mounting groove 1131S1a, the second mounting groove 1131S2a, and the third mounting groove 1131S3a may at least partially overlap with the tilting guide in a first direction (X-axis direction) or a second direction (Y-axis direction) corresponding to the first magnet 1151a, the second magnet 1151b, and the third magnet 1151c, as will be described below. For example, the first protrusion of the tilting guide may overlap with the first mounting groove 1131S1a and the second mounting groove 1131S2a in the second direction (Y-axis direction). Furthermore, a portion of the base of the tilting guide may overlap with the first mounting groove 1131S1a and the second mounting groove 1131S2a in the second direction (Y-axis direction). Additionally, at least a portion of the tilting guide may overlap with the third mounting groove 1131S3a in the first direction (X-axis direction). With this configuration, tilting can be performed as described below.

[0218] The fourth retainer outer surface 1131S4 may be an outer surface that contacts the first retainer outer surface 1131S1 and the second retainer outer surface 1131S2 and extends from the first retainer outer surface 1131S1 and the second retainer outer surface 1131S2 along a first direction (X-axis direction). Furthermore, the fourth retainer outer surface 1131S4 may be located between the first retainer outer surface 1131S1 and the second retainer outer surface 1131S2. In other words, the fourth retainer outer surface 1131S4 may be positioned facing the fifth housing side.

[0219] The outer surface 1131S4 of the fourth retainer may include a fourth mounting groove 1131S4a. An inclined guide portion 1141 may be located within the fourth mounting groove 1131S4a. Furthermore, the fastening member 1131a and the fifth housing side portion 1126 may be located within the fourth mounting groove 1131S4a. Additionally, the fourth mounting groove 1131S4a may include multiple regions. These multiple regions may include a first region AR1, a second region AR2, and a third region AR3.

[0220] The fastening member 1131a may be located in the first region AR1. Specifically, the member base portion of the fastening member 1131a may be located in the first region AR1. In other words, the first region AR1 may overlap with the fastening member 1131a in the first direction (X-axis direction). In this case, the first region AR1 may be located above the outer surface 1131S4 of the fourth retainer. In other words, the first region AR1 may correspond to the region located above the fourth mounting groove 1131S4a. In this case, the first region AR1 may not be a region within the fourth mounting groove 1131S4a.

[0221] The fifth housing side portion 1126 can be located within the second region AR2. In other words, the second region AR2 can overlap with the fifth housing side portion 1126 in the first direction (X-axis direction).

[0222] Furthermore, the second region AR2 can be located on the outer surface 1131S4 of the fourth retainer, just like the first region. In other words, the second region AR2 can correspond to the region located on the upper part of the fourth mounting groove 1131S4a.

[0223] The tilting guide can be located in the third region AR3. In particular, the base of the tilting guide can be located in the third region AR3. In other words, the third region AR3 can overlap with the tilting guide (e.g., the base) in the first direction (X-axis direction).

[0224] Furthermore, the second region AR2 can be located between the first region AR1 and the third region AR3.

[0225] Furthermore, a fastening member may be disposed in the first region AR1, and a first groove gr1 may be located in the fastening member 1131a. In an embodiment, the fastening member 1131a may include a first groove gr1 formed in the inner surface 1131aas. Additionally, a first magnetic body may be disposed in the first groove gr1 as described above. In other words, the first magnetic body may also be located in the first region AR1.

[0226] Furthermore, as described above, the fifth housing side can be disposed in the second region AR2. The first groove gr1 can be positioned facing the second groove gr2. For example, the first groove gr1 can at least partially overlap with the second groove gr2 in the third direction (Z-axis direction).

[0227] Furthermore, the repulsive force generated by the second magnetic body can be transmitted to the fourth mounting groove 1131S4a of the retainer 1131 through the fastening member. Therefore, the retainer can apply force to the inclined guide in the same direction as the repulsive force generated by the second magnetic body.

[0228] The fifth housing side may include a second groove gr2 formed on its outer surface facing the first groove gr1. Furthermore, as described above, the fifth housing side may include a second receiving groove formed on its inner surface. Additionally, a second protrusion may be disposed within the second receiving groove.

[0229] Furthermore, like the second magnetic body, the repulsive force generated by the first and second magnetic bodies can be applied to the side of the fifth housing. Therefore, the side of the fifth housing and the fastening member can be pressed against the inclined guide portion provided between the side of the fifth housing and the retainer 1131 by the repulsive force.

[0230] The tilt guide 1141 can be set in the third region AR3.

[0231] Furthermore, the first receiving groove PH1 can be located in the fourth placement groove 1131S4a. Additionally, the first protrusion of the tilting guide 1141 can be received in the first receiving groove PH1. Therefore, the first protrusion PR1 can contact the first receiving groove. The maximum diameter of the first receiving groove PH1 can correspond to the maximum diameter of the first protrusion PR1. This can also be applied in the same way to the second receiving groove and the second protrusion PR2. In other words, the maximum diameter of the second receiving groove can correspond to the maximum diameter of the second protrusion PR2. Therefore, the second protrusion can contact the second receiving groove. With this configuration, the first axis tilt can be easily performed relative to the first protrusion, and the second axis tilt can be easily performed relative to the second protrusion, thereby increasing the tilt radius.

[0232] Furthermore, in the embodiments, multiple first receiving grooves PH1 may exist. For example, either the first receiving groove PH1 or the second receiving groove PH2 may include a 1-1 receiving groove PH1a and a 1-2 receiving groove PH1b. The first receiving groove PH1 will be described below as including the 1-1 receiving groove PH1a and the 1-2 receiving groove PH1b. Furthermore, the following description can also be applied to the second receiving groove PH2 in the same manner. For example, the second receiving groove PH2 may include a 2-1 receiving groove and a 2-2 receiving groove; the description of the 1-1 receiving groove can be applied to the 2-1 receiving groove, and the description of the 1-2 receiving groove can be applied to the 2-2 receiving groove.

[0233] Receiving grooves PH1a (1-1) and PH1b (1-2) can be arranged side by side in the first direction (X-axis direction). Receiving grooves PH1a (1-1) and PH1b (1-2) can have the same maximum area.

[0234] Multiple first receiving grooves PH1 can have different numbers of inclined surfaces. For example, a first receiving groove PH1 can include a groove bottom surface and an inclined surface. In this case, multiple receiving grooves can have different numbers of inclined surfaces. Furthermore, the bottom surfaces of the receiving grooves can also have different areas.

[0235] For example, 1-1 receiving groove PH1a may include a first groove bottom surface LS1 and a first inclined surface CS1. 1-2 receiving groove PH1b may include a second groove bottom surface LS2 and a second inclined surface CS2.

[0236] In this case, the first groove bottom surface LS1 and the second groove bottom surface LS2 can have different areas. The area of ​​the first groove bottom surface LS1 can be smaller than the area of ​​the second groove bottom surface LS2.

[0237] Furthermore, the number of first inclined surfaces CS1 that contact the bottom surface LS1 of the first groove can be different from the number of second inclined surfaces CS2. For example, the number of first inclined surfaces CS1 can be greater than the number of second inclined surfaces CS2.

[0238] With this configuration, the assembly tolerance of the first protrusion disposed in the first receiving groove PH1 can be easily compensated. For example, since the number of first inclined surfaces CS1 is greater than the number of second inclined surfaces CS2, the first protrusion can contact more inclined surfaces, and therefore the position of the first protrusion in the 1-1 receiving groove PH1a can be maintained more accurately.

[0239] In contrast, in the 1-2 receiving groove PH1b, since the number of inclined surfaces in contact with the first protrusion is less than the number of inclined surfaces in the 1-1 receiving groove PH1b, the position of the first protrusion can be easily adjusted.

[0240] In this embodiment, the second inclined surfaces CS2 can be spaced apart from each other in the second direction (Y-axis direction). Furthermore, the bottom surface LS2 of the second groove can extend in the first direction (X-axis direction), and the first protrusion can be easily moved in the first direction (X-axis direction) while in contact with the second inclined surfaces CS2. In other words, the position of the first protrusion can be easily adjusted within the 1-2 receiving grooves PH1.

[0241] Furthermore, in this embodiment, the first region AR1, the second region AR2, and the third region AR3 may have different heights in the first direction (X-axis direction). In this embodiment, the first region AR1 may have a greater height than the second region AR2 and the third region AR3 in the first direction (X-axis direction). Therefore, a step may be provided between the first region AR1 and the second region AR2.

[0242] Furthermore, the fastening member 1131a may include a first groove gr1. In other words, the first engaging groove gr1 may be located on the inner surface of the member base portion 1131aa. Furthermore, the aforementioned first magnetic body may be disposed in the first groove gr1. Moreover, depending on the number of first magnetic bodies, multiple first fastening grooves gr1 may exist. In other words, the number of first fastening grooves gr1 may correspond to the number of first magnetic bodies.

[0243] Furthermore, the area of ​​the first groove gr1 can be different from the area of ​​the second groove. For example, the area of ​​the first groove gr1 can be larger than the area of ​​the second groove. Therefore, the center of gravity can move adjacent to the tilting guide. Thus, the difference in driving force due to posture differences can be reduced, and the current consumption for rotation can be minimized.

[0244] In addition, the fastening member 1131a may include a member base portion 1131aa, a first extension portion 1131ab, and a second extension portion 1131ac.

[0245] The component base portion 1131aa may be located on the outermost side of the first camera actuator. The component base portion 1131aa may be located on the outer side of the fifth housing side portion. In other words, the fifth housing side portion may be located between the component base portion 1131aa and the tilting guide portion.

[0246] The first extension 1131ab can extend from the edge of the component base portion 1131aa along a third direction (Z-axis direction). Furthermore, the first extension 1131ab can be bent and then extended in a second direction (Y-axis direction). For example, the first extension 1131ab can extend in the opposite direction to the direction toward the first groove gr1. In other words, the first extension 1131ab can extend from the component base portion 1131aa toward the retainer 1131. The same applies to the second extension 1131ac. Furthermore, the second extension 1131ac can extend from the edge of the component base portion 1131aa along a third direction (Z-axis direction). In an embodiment, the first extension 1131ab and the second extension 1131ac can be located on the edge of the component base portion 1131aa in the second direction (Y-axis direction). Furthermore, the first extension 1131ab and the second extension 1131ac can be disposed between the upper component and the lower component.

[0247] Therefore, the fastening member 1131a can have a groove formed by the first extension 1131ab and the second extension 1131ac. In other words, the groove can be located between the first extension 1131ab and the second extension 1131ac. Therefore, the first extension 1131ab and the second extension 1131ac can be connected to each other only through the member base portion 1131aa. With this configuration, the fastening member 1131a can continuously receive the repulsive force generated by the first magnetic body disposed in the center of the member base portion 1131aa, particularly in the first groove gr1.

[0248] Furthermore, since the fastening member 1131a is combined with the retainer and moves when tilted along the X-axis and Y-axis, the rigidity of the fastening member 1131a can be greater than that of the side of the fifth housing.

[0249] Furthermore, as described above, the fifth housing side according to the embodiment may have an upper member and a lower member, thereby increasing rigidity. This configuration reduces the rigidity difference between the fastening member and the fifth housing side. Therefore, when the fastening member 1131a and the retainer 1131 coupled to the fastening member 1131a are tilted together along the X-axis or Y-axis, the fastening member 1131a may have a small distance adjacent to the fifth housing side and may contact the fifth housing side. Therefore, as described above, due to the improved rigidity of the fifth housing side, the fifth housing side can easily function as a stop. In other words, the reliability of the camera actuator can be improved.

[0250] Furthermore, the first extension 1131ab can be spaced apart from the second extension 1131ac in the second direction (Y-axis direction) to form a separation space. The fifth housing side and the inclined guide can be disposed in the separation space. In addition, the second magnetic body and the first magnetic body can be located in the separation space.

[0251] Furthermore, the first extension 1131ab and the second extension 1131ac can have the same length in the third direction (Z-axis direction). Therefore, the bonding force, weight, etc. are formed in a balanced manner, so the retainer can be tilted accurately without tilting to one side.

[0252] Furthermore, the first extension 1131ab and the second extension 1131ac can be bonded to the retainer. It should be understood in this specification that bonding can refer to bonding via adhesive members other than the aforementioned protrusions and grooves. In an embodiment, the first extension 1131ab and the second extension 1131ac may include outwardly opening bonding grooves 1131L. Adhesive members (e.g., epoxy resin) can be applied through the bonding grooves 1131L, and the first extension 1131ab and the second extension 1131ac can be easily bonded to the outer surface of the retainer or the fourth retainer. However, it should be understood in this specification that the position of the protrusions and grooves for bonding can also be changed.

[0253] Figure 9a This is a perspective view of the tilt guide portion of the first camera actuator according to an embodiment. Figure 9b In the context of Figure 9a Perspective views from different directions, Figure 9c It is along Figure 9a The sectional view taken by line F-F' in the middle.

[0254] The tilting guide 1141 according to this embodiment may include a base BS, a first protrusion PR1 protruding from a first surface 1141a of the base BS, and a second protrusion PR2 protruding from a second surface 1141b of the base BS. Furthermore, depending on the structure, the first and second protrusions may be formed on opposing surfaces, but the following description will be based on the accompanying drawings. It should also be understood that the first and second protrusions PR1 and PR2 may be integrally formed with the base BS, and as shown, the first and second protrusions PR1 and PR2 may have a spherical shape, like a ball. For example, in the tilting guide 1141, the base BS may include grooves at positions corresponding to the first and second protrusions PR1 and PR2. Furthermore, a ball may be inserted into the groove of the base BS. Additionally, the tilting guide 1141 may also have a structure in which the aforementioned protrusions (first or second protrusions), the groove of the base BS, and the ball inserted into the groove are combined in various ways.

[0255] First, the base BS may include a first surface 1141a and a second surface 1141b opposite to the first surface 1141a. In other words, the first surface 1141a may be spaced apart from the second surface 1141b in a third direction (Z-axis direction), and the first surface 1141a and the second surface 1141b may be outer surfaces that are opposite or facing each other in the inclined guide portion 1141. For example, the first surface 1141a is the surface adjacent to the retainer, and the second surface 1141b is the surface adjacent to the side of the fifth housing.

[0256] The tilting guide 1141 may include a first protrusion PR1 extending to one side of the first surface 1141a. According to an embodiment, the first protrusion PR1 may protrude from the first surface 1141a toward the retainer. Multiple first protrusions PR1 may be present, and the multiple first protrusions PR1 may include 1-1 protrusion PR1a and 1-2 protrusions PR1b.

[0257] Protrusions 1-1 PR1a and 1-2 PR1b can be arranged side-by-side in the second direction (Y-axis direction). In other words, protrusions 1-1 PR1a and 1-2 PR1b can overlap in the second direction (Y-axis direction). Furthermore, in the embodiment, protrusions 1-1 PR1a and 1-2 PR1b can be equally divided by virtual lines VL1 or VL2 extending in the first direction (X-axis direction) or the second direction (Y-axis direction) or by a surface.

[0258] Furthermore, protrusions PR1a (1-1) and PR1b (1-2) can have curvature, for example, a hemispherical shape. Therefore, the center of the first protrusion PR1 can be located on the first surface 1141a. Thus, rotation (Y-axis tilt) of the tilting guide can be performed relative to the first surface 1141a.

[0259] Furthermore, an alignment groove can be provided in the first surface 1141a. The alignment groove can be provided on one side of the first surface 1141a and can provide the assembly position or assembly direction of the tilt guide 1141 during assembly.

[0260] Furthermore, the tilting guide 1141 may include a second protrusion PR2 extending to one side of the second surface 1141b. According to an embodiment, the second protrusion PR2 may protrude from the second surface 1141b into the housing. Additionally, in an embodiment, multiple second protrusions PR2 may be present, and the multiple second protrusions PR2 may include 2-1 protrusions PR2a and 2-2 protrusions PR2b. Similarly, since the center of the second protrusion PR2 may be located on the second surface 1141b, rotation (X-axis tilt) of the tilting guide may be performed relative to the second surface 1141b.

[0261] Protrusions 2-1 PR2a and 2-2 PR2b can be arranged side-by-side in a first direction (X-axis direction). In other words, protrusions 2-1 PR2a and 2-2 PR2b can overlap in the first direction (X-axis direction). Furthermore, in an embodiment, protrusions 2-1 PR2a and 2-2 PR2b can be equally divided by virtual lines VL1' or VL2' extending in the first direction (X-axis direction) or the second direction (Y-axis direction) or by a surface.

[0262] Protrusions 2-1 PR2a and 2-2 PR2b may have curvature, for example, a hemispherical shape. Furthermore, protrusions 2-1 PR2a and 2-2 PR2b may contact the fastening member 1131a at points spaced apart from the second surface 1141b of the base BS.

[0263] Protrusions 1-1 PR1a and 1-2 PR1b can be located in the region between protrusions 2-1 PR2a and 2-2 PR2b in the second direction. According to an embodiment, protrusions 1-1 PR1a and 1-2 PR1b can be located in the center of the separation space between protrusions 2-1 PR2a and 2-2 PR2b in the first direction. With this configuration, the actuator according to the embodiment can have an X-axis tilt angle within the same range relative to the X-axis. In other words, the tilt guide 1141 can provide a range in which the retainer can be tilted (e.g., negative / positive range) about protrusions 1-1 PR1a and 1-2 PR1b in the same way relative to the Y-axis.

[0264] Furthermore, protrusions 2-1 PR2a and 2-2 PR2b can be located in the region between protrusions 1-1 PR1a and 1-2 PR1b in the second direction. According to an embodiment, protrusions 2-1 PR2a and 2-2 PR2b can be located at the center of the separation space between protrusions 1-1 PR1a and 1-2 PR1b in the first direction. With this configuration, the actuator according to the embodiment can have an X-axis tilt angle within the same range relative to the X-axis. In other words, the actuator can provide a range in which the tilt guide 1141 and the retainer can be tilted (e.g., negative / positive range) about protrusions 2-1 PR2a and 2-2 PR2b in the same way relative to the X-axis.

[0265] Specifically, the first surface 1141a may include a first outer line M1, a second outer line M2, a third outer line M3, and a fourth outer line M4. The first outer line M1 and the second outer line M2 may face each other, and the third outer line M3 and the fourth outer line M4 may also face each other. Furthermore, the third outer line M3 and the fourth outer line M4 may be located between the first outer line M1 and the second outer line M2. Additionally, the first outer line M1 and the second outer line M2 may be perpendicular to the first direction (X-axis direction), but the third outer line M3 and the fourth outer line M4 may be parallel to the first direction (X-axis direction).

[0266] In this configuration, the first protrusion PR1 can be located on the second virtual line VL2. Here, the first virtual line VL1 is the line that bisects the first outer line M1 and the second outer line M2. Alternatively, the first virtual line VL1 and the third virtual line VL1' are the lines that bisect the base BS in the second direction (Y-axis direction). Therefore, the tilt guide 1141 can be easily tilted along the Y-axis via the first protrusion PR1. Furthermore, since the tilt guide 1141 is tilted along the Y-axis relative to the second virtual line VL2, rotational force can be applied evenly to the tilt guide 1141. Therefore, X-axis tilting can be performed precisely, improving the reliability of the device.

[0267] Furthermore, protrusions PR1a (1-1) and PR1b (1-2) can be arranged symmetrically with respect to the first virtual line VL1 and the second virtual line VL2. Alternatively, protrusions PR1a (1-1) and PR1b (1-2) can be arranged symmetrically with respect to the first center point C1. With this configuration, when tilted along the Y-axis, the supporting force supported by the first protrusion PR1 can be applied evenly above and below the second virtual line VL2. Therefore, the reliability of the tilting guide can be improved. Here, the second virtual line VL2 is the line that bisects the third outer line M3 and the fourth outer line M4. Alternatively, the second virtual line LV2 and the fourth virtual line LV2' are the lines that bisect the base BS in the first direction (X-axis direction).

[0268] Furthermore, the first center point C1 can be the intersection of the first virtual line VL1 and the second virtual line VL2. Alternatively, the first center point C1 can be located at a point corresponding to (e.g., overlapping with) the center of gravity in a third direction, depending on the shape of the inclined guide 1141.

[0269] Furthermore, the second surface 1141b may include a fifth outer line M1', a sixth outer line M2', a seventh outer line M3', and an eighth outer line M4'. The fifth outer line M1' and the sixth outer line M2' may face each other, and the seventh outer line M3' and the eighth outer line M4' may also face each other. Additionally, the seventh outer line M3' and the eighth outer line M4' may be located between the fifth outer line M1' and the sixth outer line M2'. Furthermore, the fifth outer line M1' and the sixth outer line M2' may be perpendicular to the first direction (X-axis direction), but the seventh outer line M3' and the eighth outer line M4' may be parallel to the first direction (X-axis direction).

[0270] Furthermore, since the tilt guide 1141 tilts relative to the third virtual line VL1' along the X-axis, rotational force can be applied evenly to the tilt guide 1141. Therefore, X-axis tilting can be performed precisely, improving the reliability of the device.

[0271] Furthermore, protrusions PR2a (2-1) and PR2b (2-2) can be symmetrically arranged on the third virtual line VL1' relative to the fourth virtual line VL2'. Alternatively, protrusions PR2a (2-1) and PR2b (2-2) can be symmetrically arranged relative to the second center point C1'. With this configuration, when the X-axis is tilted, the supporting force supported by the second protrusion PR2 can be applied equally to the left and right sides of the tilt guide relative to the third virtual line VL1'. Therefore, the reliability of the tilt guide can be improved. Here, the third virtual line VL1' is the line that equally bisects the fifth outer line M1' and the sixth outer line M2'. Furthermore, the second center point C1' can be the intersection of the third virtual line VL1' and the fourth virtual line VL2'. Alternatively, the second center point C1' can also be a point corresponding to the center of gravity, depending on the shape of the tilt guide 1141.

[0272] Furthermore, the distance between protrusions 1-1 PR1a and 1-2 PR1b in the second direction (Y-axis direction) can be greater than the length of the second protrusion PR2 in the second direction (Y-axis direction). Therefore, when tilted along the Y-axis relative to protrusions 1-1 PR1a and 1-2 PR1b, the drag generated by the second protrusion PR2 can be minimized.

[0273] Accordingly, the distance between protrusions 2-1 PR2a and 2-2 PR2b in the first direction (X-axis direction) can be greater than the length of the first protrusion PR1 in the first direction (X-axis direction). Therefore, when tilted along the X-axis relative to protrusions 2-1 PR2a and 2-2 PR2b, the resistance generated by the first protrusion PR1 can be minimized.

[0274] Figure 10 This is a view showing the first drive section of the first camera actuator according to an embodiment.

[0275] refer to Figure 10 The first driving unit 1150 includes a first driving magnet 1151, a first driving coil 1152, a Hall sensor unit 1153, a first plate unit 1154, and a yoke unit 1155.

[0276] Furthermore, as described above, the first driving magnet 1151 may include a first magnet 1151a, a second magnet 1151b, and a third magnet 1151c to provide driving force via electromagnetic force. Each of the first magnet 1151a, the second magnet 1151b, and the third magnet 1151c may be disposed adjacent to the outer surface of the retainer 1131. For example, each of the first magnet 1151a, the second magnet 1151b, and the third magnet 1151c may be located in a groove on the outer surface of the retainer 1131.

[0277] Furthermore, the first drive coil 1152 may include multiple coils. In an embodiment, the first drive coil 1152 may include at least one coil, and the at least one coil may be positioned to correspond to at least one magnet of the first drive magnet described above. For example, the first drive coil 1152 may include a first coil 1152a, a second coil 1152b, and a third coil 1152c.

[0278] The first coil 1152a can be positioned relative to the first magnet 1151a. Therefore, as described above, the first coil 1152a can be located in the first housing hole 1121a of the first housing side portion 1121. Furthermore, the second coil 1152b can be positioned relative to the second magnet 1151b. Therefore, as described above, the second coil 1152b can be located in the second housing hole 1122a of the second housing side portion 1122.

[0279] According to the embodiment, the second camera actuator can provide optimal optical characteristics by controlling the rotation of the mover 1130 along the first axis (X-axis direction) or the second axis (Y-axis direction) by the electromagnetic force between the first drive magnet 1151 and the first drive coil 1152, thereby minimizing the occurrence of eccentricity or tilt when implementing OIS.

[0280] Furthermore, according to embodiments, an ultra-thin and ultra-small camera actuator and a camera module including the camera actuator can be provided. The camera actuator can implement OIS through the tilt guide 1141 of the rotating part 1140 disposed between the first housing 1120 and the mover 1130, thereby eliminating the size limitation of the actuator.

[0281] The first plate portion 1154 may include a first plate side portion 1154a, a second plate side portion 1154b, and a third plate side portion 1154c.

[0282] The first plate side portion 1154a and the second plate side portion 1154b can be configured to face each other. In addition, the third plate side portion 1154c can be located between the first plate side portion 1154a and the second plate side portion 1154b.

[0283] Furthermore, the first plate side portion 1154a may be located between the first housing side portion and the shielding cover, and the second plate side portion 1154b may be located between the second housing side portion and the shielding cover. Furthermore, the third plate side portion 1154c may be located between the third housing side portion and the shielding cover, and may be the bottom surface of the first plate portion 1154.

[0284] The first plate side portion 1154a can be coupled to and electrically connected to the first coil 1152a. Furthermore, the first plate side portion 1154a can be coupled to and electrically connected to the first Hall sensor 1153a.

[0285] The second plate side portion 1154b can be coupled to and electrically connected to the second coil 1152b. It should be understood that the second plate side portion 1154b can also be coupled to and electrically connected to the first Hall sensor.

[0286] The third plate side portion 1154c can be coupled to and electrically connected to the third coil 1152c. Furthermore, the third plate side portion 1154c can be coupled to and electrically connected to the second Hall sensor 1153b.

[0287] The yoke 1155 may include a first yoke 1155a, a second yoke 1155b, and a third yoke 1155c. The first yoke 1155a may be located in a first mounting groove and engaged with a first magnet 1151a. Furthermore, the second yoke 1155b may be located in a second mounting groove and engaged with a second magnet 1151b. Furthermore, the third yoke 1155c may be located in a third mounting groove and engaged with a third magnet 1151c. The first yokes 1155a to the third yokes 1155c facilitate the placement of the first magnet 1151a to the third magnet 1151c in the first to third mounting grooves and their engagement with the housing.

[0288] Figure 11a This is a perspective view of the first camera actuator according to an embodiment. Figure 11b It is along Figure 11a The sectional view taken by line P-P' in the middle. Figure 11c yes Figure 11b A magnified view of part of K1, Figure 11d yes Figure 11b A magnified view of part of K2, and Figure 11e It is along Figure 11a The sectional view taken by line Q-Q' in the middle.

[0289] refer to Figures 11a to 11e The first coil 1152a can be located on the side portion 1121 of the first housing, and the first magnet 1151a can be located on the outer surface 1131S1 of the first holder of the holder 1131. Therefore, the first coil 1152a and the first magnet 1151a can be arranged opposite to each other. The first magnet 1151a can at least partially overlap with the first coil 1152a in the second direction (Y-axis direction).

[0290] Furthermore, the second coil 1152b can be located on the side portion 1122 of the second housing, and the second magnet 1151b can be located on the outer surface 1131S2 of the second retainer of the retainer 1131. Therefore, the second coil 1152b and the second magnet 1151b can be arranged opposite to each other. The second magnet 1151b can at least partially overlap with the second coil 1152b in the second direction (Y-axis direction).

[0291] Furthermore, the first coil 1152a and the second coil 1152b can overlap in the second direction (Y-axis direction), and the first magnet 1151a and the second magnet 1151b can overlap in the second direction (Y-axis direction).

[0292] With this configuration, the electromagnetic force applied to the outer surfaces of the retainers (the outer surfaces of the first and second retainers) can be located on an axis parallel to the second direction (the Y-axis direction), thereby precisely and accurately performing X-axis tilting.

[0293] Furthermore, the second protrusions PR2a and PR2b of the tilting guide 1141 can contact the fifth housing side 1126 of the first housing 1120. The second protrusion PR2 can be disposed in a second receiving groove PH2 formed in a side surface of the fifth housing side 1126. Moreover, when X-axis tilting is performed, the second protrusions PR2a and PR2b can be tilted reference axes (or rotation axes). Therefore, the tilting guide 1141 and the mover 1130 can move in a second direction.

[0294] Furthermore, as described above, the first Hall sensor 1153a can be disposed on the outer side for electrical connection and engagement with the first plate portion 1154. However, the present invention is not limited to these locations.

[0295] Furthermore, the third coil 1152c can be located on the third housing side 1123, and the third magnet 1151c can be located on the third retainer outer surface 1131S3 of the retainer 1131. The third coil 1152c and the third magnet 1151c can at least partially overlap in the first direction (X-axis direction). Therefore, the strength of the electromagnetic force between the third coil 1152c and the third magnet 1151c can be easily controlled.

[0296] As described above, the tilt guide 1141 may be located on the fourth outer surface 1131S4 of the retainer 1131. Furthermore, the tilt guide 1141 may be disposed in the fourth mounting groove 1131S4a on the outer surface of the fourth retainer. As described above, the fourth mounting groove 1131S4a may include the first region, the second region, and the third region described above.

[0297] The fastening member 1131a may be disposed in the first region, and the fastening member 1131a may include a first groove gr1 formed in its inner surface. Furthermore, as described above, a first magnetic body 1142 may be disposed in the first groove gr1, and the repulsive force RF2 generated by the first magnetic body 1142 can be transmitted through the fastening member 1131a to the fourth placement groove 1131S4a (RF2') of the retainer 1131. Therefore, the retainer 1131 can apply force to the inclined guide 1141 in the same direction as the repulsive force RF2 generated by the first magnetic body 1142.

[0298] A fifth housing side portion 1126 may be provided in the second region. The fifth housing side portion 1126 may include a second groove gr2 facing the first groove gr1. Furthermore, the fifth housing side portion 1126 may include a second receiving groove PH2 provided on the surface opposite to the second groove gr2. Additionally, a repulsive force RF1 generated by the second magnet 1143 may be applied to the fifth housing side portion 1126. Therefore, the fifth housing side portion 1126 and the fastening member 1131a can be pressed against the tilting guide portion 1141 provided between the fifth housing side portion 1126 and the retainer 1131 by the generated repulsive forces RF1 and RF2'. Therefore, even after tilting the retainer along the X-axis or Y-axis by applying current to the first coil and the second coil or the third coil 1152c, the connection between the retainer 1131, the first housing 1120, and the tilting guide portion 1141 can be maintained.

[0299] The tilt guide 1141 can be disposed in the third region. As described above, the tilt guide 1141 may include a first protrusion PR1 and a second protrusion PR2. In this case, the first protrusion PR1 and the second protrusion PR2 may also be disposed on the second surface and the first surface of the base, respectively. As described above, and even in other embodiments described below, the first protrusion PR1 and the second protrusion PR2 may also be located on the facing surfaces of the base in various ways.

[0300] The first receiving groove PH1 can be located in the fourth placement groove 1131S4a. Furthermore, the first protrusion PR1 of the tilting guide 1141 can be received in the first receiving groove PH1. Therefore, the first protrusion PR1 can contact the first receiving groove PH1. The maximum diameter of the first receiving groove PH1 can correspond to the maximum diameter of the first protrusion PR1. This can also be applied in the same way to the second receiving groove PH2 and the second protrusion PR2. In other words, the maximum diameter of the second receiving groove PH2 can correspond to the maximum diameter of the second protrusion PR2. Furthermore, the second protrusion PR2 can therefore contact the second receiving groove PH2. With this configuration, a first axis tilt can be easily performed relative to the first protrusion PR1, and a second axis tilt can be easily performed relative to the second protrusion PR2, thereby improving the tilt radius.

[0301] Furthermore, the tilt guide 1141 can be arranged side-by-side with the fastening member 1131a and the fifth housing side portion 1126 in the third direction (Z-axis direction), and thus the tilt guide 1141 and the optical member 1132 can partially overlap in the first direction (X-axis direction). More specifically, in the embodiment, the first protrusion PR1 can overlap with the optical member 1132 in the first direction (X-axis direction). Furthermore, at least a portion of the first protrusion PR1 can overlap with the third coil 1152c or the third magnet 1151c in the first direction (X-axis direction). In other words, in the camera actuator according to this embodiment, each protrusion serving as the tilting central axis can be arranged adjacent to the center of gravity of the mover 1130. Therefore, the tilt guide can be arranged adjacent to the center of gravity of the retainer. Therefore, the camera actuator according to this embodiment can minimize the torque value for the tilt retainer, and can also minimize the current consumption applied to the coil portion, etc., for the tilt retainer, thereby improving power consumption and device reliability.

[0302] Furthermore, the first magnetic body 1142 and the second magnetic body 1143 may not overlap with the third coil 1152c or the optical component 1132 in the first direction (X-axis direction). In other words, in the embodiment, the first magnetic body 1142 and the second magnetic body 1143 may be configured to be spaced apart from the third coil 1152c or the optical component 1132 in the third direction (Z-axis direction). Furthermore, the first magnetic body 1142 and the second magnetic body 1143 may be configured to be spaced apart from the tilt guide 1141 in a direction opposite to the third direction. Therefore, the third coil 1152c can minimize the magnetic force received from the first magnetic body 1142 and the second magnetic body 1143. Therefore, the camera actuator according to the embodiment can easily perform vertical drive (Y-axis tilt) and minimize power consumption.

[0303] Furthermore, as described above, the second Hall sensor 1153b disposed within the third coil 1153c can detect changes in magnetic flux, thereby performing position sensing between the third magnet 1151c and the second Hall sensor 1153b. In this case, the offset voltage of the second Hall sensor 1153b can change according to the influence of the magnetic field formed by the first magnetic body 1142 and the second magnetic body 1143.

[0304] In the first camera actuator according to the embodiment, the fastening member 1131a, the first magnetic body 1142, the second magnetic body 1143, the fifth housing side portion 1126, the tilt guide portion 1141, and the retainer 1131 can be arranged sequentially. However, since the first magnetic body can be located on the fastening member and the second magnetic body can be located on the fifth housing side portion, the fastening member, the fifth housing side portion, the tilt guide portion, and the retainer can be arranged sequentially.

[0305] Furthermore, in the embodiment, the separation distance between the first magnetic body 1142 and the second magnetic body 1143 and the holder 1131 (or optical component 1132) in a third direction can be greater than the separation distance with the tilt guide 1141. Therefore, the second Hall sensor 1153b below the holder 1131 can also be configured to be spaced apart from the first magnetic body 1142 and the second magnetic body 1143 by a predetermined distance. Thus, the influence of the magnetic field formed by the first magnetic body 1142 and the second magnetic body 1143 in the second Hall sensor 1153b can be minimized, thereby preventing the Hall voltage from concentrating to a positive or negative value and saturating. In other words, with this configuration, the Hall electrode can have a range within which Hall calibration can be performed. In addition, temperature also affects the electrodes of the Hall sensor, and the resolution of the camera lens varies with temperature, but in the embodiment, by preventing the Hall voltage from concentrating to a positive or negative value, the resolution of the lens can also be compensated in response to this, thereby easily preventing a reduction in resolution.

[0306] Furthermore, circuitry for compensating for the offset of the output (i.e., Hall voltage) of the second Hall sensor 1153b can be easily designed.

[0307] In addition to the first protrusion PR1 and the second protrusion PR2, the inclined guide portion 1141 can be positioned relative to the base into the fourth mounting groove 1131S4a. In other words, the length of the base BS in the third direction (Z-axis direction) can be less than the length of the fourth mounting groove 1131S4a in the third direction (Z-axis direction). With this configuration, miniaturization can be easily achieved.

[0308] Furthermore, 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 located between the outer surface of the fourth retainer and the fifth housing side portion 1126. In other words, at least a portion of the second protrusion PR2 can be located in a direction opposite to the third direction (Z-axis direction) from the retainer 1131. In other words, the retainer 1131 can be spaced a predetermined distance from the end of the second protrusion PR2 (the portion that contacts the second receiving groove) in the third direction (Z-axis direction).

[0309] The fifth housing side 1126 may have an inwardly extending and bent structure. Furthermore, a portion of the fastening member 1131a may be located within a groove formed by the extended and bent structure of the fifth housing side 1126. With this configuration, the fastening member 1131a can be located inside the fifth housing side 1126, thereby improving space efficiency and achieving miniaturization. Moreover, even when performing actuation via electromagnetic force (tilting or rotation of the mover 1130), the fastening member 1131a does not protrude outside the fifth housing side 1126, thus preventing contact with surrounding equipment. Therefore, reliability can be improved.

[0310] Furthermore, a predetermined separation space may exist between the first magnetic body 1142 and the second magnetic body 1143. In other words, the first magnetic body 1142 and the second magnetic body 1143 may be opposite each other with the same polarity.

[0311] Furthermore, as described above, the first drive unit can rotate and drive the mover 1130 within the first housing relative to a first direction (X-axis direction) or a second direction (Y-axis direction). In this case, the drive magnet in the first drive unit may include at least one magnet, and the drive coil may also include at least one coil. In this case, at least a portion of the at least one magnet may overlap with the tilt guide 1141 in the first direction (X-axis direction) or the second direction (Y-axis direction). Furthermore, at least a portion of the at least one coil may also overlap with the tilt guide 1141 in the first direction (X-axis direction) or the second direction (Y-axis direction).

[0312] The first magnet 1151a and the second magnet 1151b can overlap in the second direction (Y-axis direction), and the tilting guide 1141 can be located in the region between the first magnet 1151a and the second magnet 1151b in the second direction (Y-axis direction).

[0313] A portion of the tilting guide portion 1141 may be located between the first magnet 1151a and the second magnet 1151b, and may overlap with the first magnet 1151a and the second magnet 1151b in the second direction (Y-axis direction).

[0314] For example, the first protrusion PR1 of the tilt guide 1141 may overlap with the first magnet 1151a and the second magnet 1151b in the second direction (Y-axis direction). In this case, the first protrusion PR1 may be located between the mover 1130 and the base BS of the tilt guide 1141.

[0315] Therefore, the separation distance between the first magnet 1151a and the second magnet 1151b and the tilt guide 1141 in the third direction (Z-axis direction) can be reduced. In other words, the first magnet 1151a and the second magnet 1151b can be disposed adjacent to the tilt guide 1141. Therefore, the center of gravity of the holder 1131 on which the first magnet 1151a and the second magnet 1151b are disposed, or the mover 1130 including the holder 1131, can be disposed adjacent to the tilt guide 1141. In other words, the center of gravity of the holder 1131 or the mover 1130 including the holder 1131 can be adjacent to the tilt guide 1141 having a rotating shaft or rotating surface for rotational drive, thus reducing the variation in torque or energy (e.g., current) consumed for tilting at a specific angle according to the posture of the camera actuator or camera module. In other words, the effects caused by different postures can be reduced. Therefore, the camera actuator and camera module according to the embodiment can perform tilting drive more accurately. Furthermore, since the aforementioned shift in the center of gravity becomes closer to the axis of rotation or the surface of rotation, the electromagnetic force that causes the mover (or retainer) to rotate can be reduced. In other words, the energy efficiency of driving the camera actuator or camera module can be improved. In other words, the first drive unit can be disposed adjacent to the tilt guide unit 1141. In this case, the first drive unit refers to the first drive magnet and the first drive coil, each of which will be described below.

[0316] Furthermore, the base BS of the tilting guide 1141 can at least partially overlap with the first magnet 1151a and the second magnet 1151b in the second direction (Y-axis direction). Therefore, the first magnet 1151a and the second magnet 1151b can be positioned closer to the tilting guide 1141. However, when the first magnet 1151a and the second magnet 1151b are located in front of the rotation axis or the rotation surface, the electromagnetic force required for tilting in the second direction (Y-axis direction) increases. Therefore, the centers of the first magnet 1151a and the second magnet 1151b (the points that divide the two magnets equally in the third direction) can be positioned spaced apart from the first protrusion PR1 in the third direction (Z-axis direction) and do not overlap in the second direction (Y-axis direction). Furthermore, the centers of the first magnet 1151a and the second magnet 1151b (the points that divide the two magnets equally in the third direction) can be located at the rear end of the first protrusion PR1, i.e., towards the third direction (Z-axis direction).

[0317] Accordingly, the base BS of the tilt guide 1141 can at least partially overlap with the first coil 1152a and the second coil 1152b in the second direction (Y-axis direction). Therefore, like the first and second magnets described above, the first coil 1152a and the second coil 1152b can be positioned closer to the tilt guide 1141. This reduces the electromagnetic force required for tilting and minimizes the effects of posture differences.

[0318] Furthermore, the third magnet disposed on the outer surface of the third holder can at least partially overlap with the first protrusion PR1 in the first direction (X-axis direction). Therefore, the center of gravity of the holder 1131 or the mover 1130 including the holder 1131 can move further toward the tilt guide 1141. Therefore, as described above, the effects of posture differences can be reduced. Therefore, the camera actuator and camera module according to the embodiment can perform tilt drive more accurately. Furthermore, since the aforementioned movement of the center of gravity becomes closer to the axis of rotation or plane of rotation, the electromagnetic force that rotates the mover (or holder) can be reduced. In other words, the energy efficiency of driving the camera actuator or camera module can be improved. The description of the third magnet can also be applied to the third coil in the same manner. In other words, the third coil can at least partially overlap with the first protrusion PR1 in the first direction.

[0319] According to an embodiment, the center of gravity of the retainer 1131 or the mover 1130 including the retainer 1131 can be positioned to overlap with the first protrusion PR1 in a third direction (Z-axis direction). Therefore, the increase in electromagnetic force variation due to differences in rotation direction or posture can be suppressed. Thus, the camera actuator and camera module according to the embodiment can accurately perform tilting.

[0320] Furthermore, as described above, the mover 1130 may include a fastening member 1131a passing through one side of the housing (e.g., the fifth housing side) and may be coupled to the housing via the fastening member 1131a. Additionally, a first groove gr1 may be present in the fastening member 1131a, and a first magnet 1142 may be located in the first groove gr1.

[0321] Furthermore, the second groove gr2 can be located on one side of the housing, for example, on the outer surface of the fifth housing side. The second groove gr2 can be positioned facing the first groove gr1 of the fastening member 1131a. Additionally, the second magnetic body 1143 can be located in the second groove gr2. Therefore, the mover 1130 and the fastening member 1131a, which is coupled to the mover 1130 and integrally performs the first and second axis tilting, are coupled to the first magnetic body 1142, and the first magnetic body 1142 and the second magnetic body 1143 are located at the front end of the tilting guide 1141, thus the center of gravity of the mover 1130 and the fastening member 1131a can be positioned closer to the tilting guide 1141 as described above. Therefore, torque variations due to posture differences can be reduced, and the electromagnetic force required for tilting can be minimized. In this case, the second magnetic body 1143 can be located in the third direction between the first magnetic body 1142 and the mover 1130.

[0322] Furthermore, the fastening member 1131a can be made of a non-magnetic material and metal. Additionally, the fastening member 1131a can have a protruding region 1131aap that protrudes in a direction opposite to the third direction (Z-axis direction), thus allowing the aforementioned center of gravity to be positioned closer to the tilting guide 1141. Furthermore, the first magnetic body 1142 and the second magnetic body 1143 can be configured to at least partially overlap with the first protrusion PR1 in the third direction (Z-axis direction), thereby minimizing the effects of posture differences.

[0323] Furthermore, the first magnetic body 1142 and the second magnetic body 1143 may have different lengths in the first direction (X-axis direction) or the second direction (Y-axis direction), thereby further reducing the variation of electromagnetic force due to posture differences.

[0324] Furthermore, the mover 1130 according to this embodiment may include a retainer 1131 and an optical component 1132. Additionally, as described above, the first driving magnet and the first driving coil may be disposed on a portion of the outer surface of the retainer 1131. In this case, the retainer 1131 may include a first sidewall and a second sidewall. Here, the first sidewall may be a first retainer outer surface, a second retainer outer surface, and a third retainer outer surface where the magnet or coil is positioned adjacent to it. Furthermore, the second sidewall may be a fourth retainer outer surface where the inclined guide 1141 is located.

[0325] Based on this, the first sidewall can be configured to be perpendicular to the second sidewall. Furthermore, the second sidewall may include a cavity in which the inclined guide portion 1141 is disposed. In this case, the cavity may correspond to the third region AR3 and may be a region formed by a fourth outer recess as the space in which the inclined guide portion 1141 is disposed. Furthermore, at least a portion of the cavity according to this embodiment may overlap with at least a portion of the first driving magnet or the first driving coil in a direction perpendicular to the optical axis. For example, the cavity may overlap with at least a portion of the first magnet and the second magnet of the first driving magnet in a second direction. Furthermore, the cavity may overlap with at least a portion of the first coil and the second coil of the first driving coil in a second direction. Furthermore, the cavity may overlap with the third magnet of the first driving magnet in a first direction. Furthermore, the cavity may overlap with the third coil of the first driving coil in a first direction.

[0326] Furthermore, at least a portion of the cavity can contact at least a portion of the tilt guide 1141. In other words, since the tilt guide 1141 can be disposed in the third region AR3, and the tilt guide 1141 is in close contact with the housing and retainer by repulsive force, at least a portion of the tilt guide 1141 can contact the cavity. In other words, at least a portion of the tilt guide 1141 can be located within the cavity.

[0327] Figure 12a This is a perspective view of the first camera actuator according to an embodiment. Figure 12b It is along Figure 12a The sectional view taken by line S-S' in the middle. Figure 12c yes Figure 12b An example diagram of the motion of the first camera actuator shown.

[0328] refer to Figures 12a to 12c Y-axis tilting can be performed in the first camera actuator according to the embodiment. In other words, OIS can be implemented by rotation in a first direction (X-axis direction).

[0329] In an embodiment, the third magnet 1151c disposed below the retainer 1131 can tilt or rotate the mover 1130 and the fastening member 1131a relative to the second direction (Y-axis direction) by generating an electromagnetic force with the third coil 1152c.

[0330] Specifically, the repulsive force between the first magnetic body 1142 and the second magnetic body 1143 can be transmitted to the fastening member 1131a and the fifth housing side 1126, and ultimately to the inclined guide portion 1141 disposed between the fifth housing side 1126 and the retainer 1131. Therefore, as described above, the inclined guide portion 1141 can be pressed by the mover 1130 and the first housing 1120 through the aforementioned repulsive force.

[0331] Furthermore, protrusions PR1a (1-1) and PR1b (1-2) may be spaced apart in the second direction (Y-axis direction) and supported by a first receiving groove PH1 formed in the fourth placement groove 1131S4a of the retainer 1131. Additionally, in this embodiment, the tilting guide 1141 may rotate or tilt about the first protrusion PR1 protruding toward the retainer 1131 (e.g., in a third direction), i.e., relative to the second direction (Y-axis direction), with the first protrusion PR1 protruding toward the retainer 1131 serving as a reference axis (or rotation axis).

[0332] For example, OIS can be achieved by using the first electromagnetic forces F1A and F1B between the third magnet 1151c disposed in the third mounting groove and the third coil portion 1152c disposed on the side of the third plate, causing the mover 1130 to rotate in the X-axis direction or in the opposite direction (X1→X1a or X1b) by a first angle θ1. The first angle θ1 can be in the range of ±1° to ±3°. However, the present invention is not limited thereto.

[0333] In the first camera actuator according to various embodiments, the electromagnetic force can move the actuator by generating a force in said direction, or move the actuator in said direction even when a force is generated in another direction. In other words, the direction of the electromagnetic force refers to the direction in which the force generated by the magnet and the coil moves the actuator.

[0334] Furthermore, the first magnetic body 1142 and the second magnetic body 1143 may have different lengths in the first direction (X-axis direction).

[0335] In this embodiment, the area of ​​the first magnetic body 1142, which is coupled to the fastening member 1131a and tilted together with the mover 1130, can be larger than the area of ​​the second magnetic body 1143. For example, the length of the first magnetic body 1142 in the first direction (X-axis direction) can be greater than the length of the second magnetic body 1143 in the first direction (X-axis direction). Furthermore, the length of the first magnetic body 1142 in the second direction (Y-axis direction) can be greater than the length of the second magnetic body 1143 in the second direction (Y-axis direction). Additionally, the second magnetic body 1143 can be located between the two ends of the first magnetic body 1142 on a virtual straight line extending upwards from a third party.

[0336] With this configuration, even when the magnetic material on one side (e.g., the second magnetic body) is tilted, forces other than vertical forces due to tilting can be easily prevented. In other words, even when the second magnetic body is tilted vertically together with the mover 1130, the mover 1130 may not receive forces (e.g., repulsive or attractive forces) against the tilt from the second magnetic body 1143. Therefore, driving efficiency can be improved.

[0337] Figure 13a It is along Figure 12a The sectional view taken by line R-R' in the middle. Figure 13b yes Figure 13a An example diagram of the motion of the first camera actuator shown.

[0338] refer to Figure 13a And 13B, can perform X-axis tilting. In other words, OIS can be achieved by tilting or rotating the mover 1130 in the Y-axis direction.

[0339] In an embodiment, the first magnet 1151a and the second magnet 1151b disposed on the retainer 1131 can generate electromagnetic force with the first coil 1152a and the second coil 1152b in the first direction (X-axis direction), thereby tilting or rotating the tilting guide 1141, the mover 1130 and the fastening member 1131a relative to the first direction (X-axis direction).

[0340] Specifically, the repulsive force between the first magnetic body 1142 and the second magnetic body 1143 can be transmitted to the fifth housing side 1126 and the retainer 1131, and ultimately to the inclined guide portion 1141 between the retainer 1131 and the fifth housing side 1126. Therefore, the inclined guide portion 1141 can be pressed by the mover 1130 and the first housing 1120 through the aforementioned repulsive force.

[0341] Furthermore, the second protrusion PR2 can be supported by the fifth housing side 1126. In this case, in the embodiment, the tilting guide 1141 can rotate or tilt about the second protrusion PR2 protruding toward the retainer 1131, i.e., relative to the first direction (X-axis direction), with the second protrusion PR2 protruding toward the retainer 1131 serving as a reference axis (or rotation axis). In other words, the tilting guide 1141 can rotate or tilt about the second protrusion PR2 protruding toward the fifth housing side 1126, i.e., in the second direction (Y-axis direction), with the second protrusion PR2 protruding toward the fifth housing side 1126 serving as a reference axis (or rotation axis).

[0342] For example, OIS can be achieved by using second electromagnetic forces F2A and F2B between the first magnet 1151a and the second magnet 1151b disposed in the first mounting groove and the first coil portion 1152a and the second coil portion 1152b disposed on the first plate side and the second plate side, causing the mover 1130 to rotate by a second angle θ2 (Y1→Y1a or Y1b) in the Y-axis direction or in the direction opposite to the Y-axis direction. The second angle θ2 can be in the range of ±1° to 3°. However, the present invention is not limited thereto.

[0343] Furthermore, as described above, the electromagnetic force generated by the first magnet 1151a and the second magnet 1151b, as well as the first coil portion 1152a and the second coil portion 1152b, can act in a third direction or in the opposite direction. For example, the electromagnetic force can be generated from the left side of the mover 1130 in the third direction (Z-axis direction), and can act from the right side of the mover 1130 in the opposite direction (Z-axis direction). Therefore, the mover 1130 can rotate relative to the first direction. Alternatively, the mover 1130 can move along the second direction.

[0344] As described above, the second camera actuator according to the embodiment can control the mover 1130 to rotate in a first direction (X-axis direction) or a second direction (Y-axis direction) by the electromagnetic force between the first drive magnet in the holder and the first drive coil disposed in the first housing, thereby providing optimal optical characteristics and minimizing the occurrence of eccentricity or tilt when implementing OIS. Furthermore, as described above, "Y-axis tilt" refers to rotation or tilt in the first direction (X-axis direction), and "X-axis tilt" refers to rotation or tilt in the second direction (Y-axis direction).

[0345] Figure 14 This is a perspective view of the first camera actuator according to an embodiment.

[0346] According to another embodiment, the first camera actuator includes a shield (not shown), a first housing 1120, a mover 1130, a rotating part 1140, and a first drive part 1150. The contents described above can be applied in the same manner, except as described below.

[0347] In the first camera actuator according to the embodiment, the connection and position of the housing 1120 and the mover 1130 may differ from those in the embodiments described above. For example, in the first camera actuator according to the above embodiments, the mover 1130 may be positioned within the housing 1120 by the repulsive force between the first magnetic body and the second magnetic body. In the first camera actuator according to this embodiment, the connection force between the housing 1120, the tilting guide 1141, and the mover 1130 may be provided by an attractive force.

[0348] More specifically, the rotating part 1140 includes a tilting guide 1141, a first magnetic body 1142 having a bonding force with the tilting guide 1141, and a second magnetic body 1143 located in the tilting guide 1141 or the housing (especially the side of the third housing). However, the first magnetic body 1142 and the second magnetic body 1143 may be located in the mover 1130, the tilting guide 1141, and the housing 1120, and may provide a bonding force between the housing 1120, the tilting guide 1141, and the mover 1130.

[0349] The tilt guide 1141 can be combined with the aforementioned mover 1130 and first housing 1120. The tilt guide 1141 can be configured adjacent to the optical axis. Therefore, the actuator according to the embodiment can easily change the optical path according to the first axis tilt and the second axis tilt, which will be described below.

[0350] The tilting guide 1141 may include a first protrusion spaced apart from each other in a first direction (X-axis direction) and a second protrusion spaced apart from each other in a second direction (Y-axis direction). Furthermore, the first and second protrusions may protrude in opposite directions. A detailed description will follow.

[0351] The first magnetic element 1142 may be located in the outer surface of the retainer 1131. In an embodiment, the first magnetic element 1142 may be located on the fourth retainer outer surface of the retainer 1131. Furthermore, the second magnetic element 1143 may be located in the housing hole 1124a of the fourth housing side portion 1124. Unlike the fourth housing hole described above, in this embodiment, a groove may be formed.

[0352] With this configuration, the tilting guide 1141 can be pressed between the retainer 1131 and the housing 1120 by the magnetic force (attraction force) between the first magnetic body 1142 and the second magnetic body 1143. Therefore, the tilting guide 1141 and the retainer 1131 in the housing 1120 can be spaced apart from the bottom surface of the housing in the receiving portion 1125. In other words, the tilting guide 1141 and the retainer 1131 can be combined with the housing 1120. However, as described above, the first magnetic body 1142 and the second magnetic body 1143 can be magnets, yokes, etc., having different or the same polarity, and can be made of materials that have attractive or repulsive forces on each other.

[0353] Figure 15 This is a perspective view of a first camera actuator according to another embodiment. Figure 16 It is along Figure 15 The sectional view taken by line B-B' in the middle. Figure 17 It is along Figure 15 The sectional view taken by line C-C' in the figure.

[0354] refer to Figures 15 to 17 The first coil portion 1152a may be located on the first housing side portion 1121, and the first magnet 1151a may be located on the first retainer outer surface 1131S1 of the retainer 1131. Therefore, the first coil portion 1152a and the first magnet 1151a may be positioned opposite or facing each other. At least a portion of the first magnet 1151a may overlap with the first coil portion 1152a in the second direction (Y-axis direction).

[0355] Furthermore, the second coil portion 1152b may be located on the second housing side portion 1122, and the second magnet 1151b may be located on the second retainer outer surface 1131S2 of the retainer 1131. Therefore, the second coil portion 1152b and the second magnet 1151b may be positioned opposite or facing each other. At least a portion of the second magnet 1151b may overlap with the second coil portion 1152b in the second direction (Y-axis direction).

[0356] Furthermore, the first coil portion 1152a and the second coil portion 1152b overlap in the second direction (Y-axis direction), and the first magnet 1151a and the second magnet 1151b overlap in the second direction (Y-axis direction). With this configuration, the electromagnetic force applied to the outer surface of the holder (the outer surface of the first holder and the outer surface of the second holder) can be located on an axis parallel to the second direction (Y-axis direction), thereby enabling precise and accurate X-axis or Y-axis tilting.

[0357] Furthermore, the first protrusion PR1 of the tilt guide 1141 can contact the first protrusion groove of the first housing 1120. Additionally, when X-axis tilting is performed, the first protrusion PR1 can be a tilted reference axis (or rotation axis). Therefore, the tilt guide 1141 and the mover 1130 can move in the left-right direction.

[0358] Furthermore, the second protrusion PR2 of the tilt guide 1141 can contact the second protrusion groove of the retainer 1131. Additionally, when performing Y-axis tilting, the second protrusion PR2 can be a tilted reference axis (or rotation axis). Therefore, the mover 1130 can tilt relative to the Y-axis, i.e., it can move upwards and downwards.

[0359] As described above, the tilting guide 1141 may be located between the fourth retainer outer surface 1131S4 of the retainer 1131 and the fourth housing side of the housing 1120.

[0360] Figure 18 This is a view showing the first drive section of a first camera actuator according to another embodiment. Figure 19 It is shown Figure 18 A view of the driving magnet, driving coil, yoke, and mover. Figure 20 This is a view showing the drive coil according to an embodiment.

[0361] refer to Figures 18 to 20 According to an embodiment, the first drive unit 1150 includes a drive magnet 1151, a drive coil 1152, a yoke 1153, a Hall sensor unit (not shown), and a first plate unit 1154. The first drive unit 1150 can move, rotate, or tilt the mover 1130.

[0362] The driving magnet 1151 may include a plurality of magnets. In an embodiment, the driving magnet 1151 may include a first magnet 1151a and a second magnet 1151b.

[0363] Each of the first magnet 1151a and the second magnet 1151b may be located on the outer surface of the holder 1131. Furthermore, the first magnet 1151a and the second magnet 1151b may be positioned facing each other. A detailed description of this will be given below.

[0364] The drive coil 1152 may include a plurality of coils. In an embodiment, the drive coil 1152 may include a first coil portion 1152a and a second coil portion 1152b.

[0365] The first coil portion 1152a can be positioned corresponding to the first magnet 1151a. In other words, the first coil portion 1152a can be configured to face the first magnet 1151a. Therefore, as described above, the first coil portion 1152a can be located in the first housing hole 1121a of the first housing side portion 1121.

[0366] Furthermore, the second coil portion 1152b can be positioned corresponding to the second magnet 1151b. In other words, the second coil portion 1152b can be configured to face the second magnet 1151b. Therefore, as described above, the second coil portion 1152b can be located in the second housing hole 1122a of the second housing side portion 1122.

[0367] Furthermore, the first coil portion 1152a can be positioned facing the second coil portion 1152b. In other words, the first coil portion 1152a can be symmetrically arranged with respect to the first direction (X-axis direction) and the second coil portion 1152b. This can also be applied in the same way to the first magnet 1151a and the second magnet 1151b. In other words, the first magnet 1151a and the second magnet 1151b can be symmetrically arranged with respect to the first direction (X-axis direction). Furthermore, the first coil portion 1152a, the second coil portion 1152b, the first magnet 1151a, and the second magnet 1151b can be configured to at least partially overlap in the second direction (Y-axis direction). With this configuration, X-axis tilting or Y-axis tilting can be accurately performed by the electromagnetic force between the first coil portion 1152a and the first magnet 1151a, and the electromagnetic force between the second coil portion 1152b and the second magnet 1151b, without tilting to one side. Here, X-axis tilting refers to tilting relative to the X-axis, and Y-axis tilting refers to tilting relative to the Y-axis.

[0368] A yoke 1153 may be located between the drive magnet 1151 and the retainer 1131. The yoke 1153 is located on the first and second outer surfaces of the retainer 1131 to facilitate easy engagement of the drive magnet with the retainer 1131. For example, the yoke 1153 may include a first yoke 1153a and a second yoke 1153b, and the yoke may be disposed in a mounting groove located on the outer surface of the retainer and may have an attractive force with the drive magnet 1151. In other words, the yoke 1153 can improve the engagement force between the drive magnet 1151 and the retainer 1131.

[0369] The Hall sensor unit (not shown) may include multiple Hall sensors. In an embodiment, the Hall sensor unit (not shown) may include a first Hall sensor (not shown) and a second Hall sensor (not shown). The first Hall sensor (not shown) may be located inside or outside the first coil unit 1152a or the second coil unit 1152b. The first Hall sensor (not shown) can detect changes in magnetic flux inside the first coil unit 1152a or the second coil unit 1152b. Therefore, position sensing between the first magnet 1151a and the second magnet 1251b and the first Hall sensor (not shown) can be performed. Therefore, the first camera actuator according to this embodiment can control the tilt of the X-axis or the Y-axis. The sensor unit may consist of multiple sensors.

[0370] The first plate portion 1154 may be disposed below the first drive portion 1150. The first plate portion 1154 may be electrically connected to the drive coil 1152 and the Hall sensor portion (not shown). For example, current can be applied to the drive coil 1152 through the first plate portion 1154, so the mover 1130 may tilt towards the X-axis or Y-axis. For example, the first plate portion 1154 may be combined with the drive coil 1152 and the Hall sensor portion (not shown) via SMT. However, the present invention is not limited to this method.

[0371] The first circuit board portion 1154 can be located between the shield (not shown) and the first housing 1120 and coupled to both the shield and the first housing 1120. The coupling method can be performed differently as described above. Furthermore, the drive coil 1152 and the Hall sensor portion (not shown) can be coupled to the outer surface of the first housing 1120.

[0372] The first circuit board portion 1154 may include a circuit board with an electrically connectable wiring pattern, such as a rigid PCB, a flexible PCB, or a rigid-flex PCB. However, the present invention is not limited to these types.

[0373] More specifically, the drive coil 1152 according to the embodiment may include a first coil portion 1152a and a second coil portion 1152b. The first coil portion 1152a and the second coil portion 1152b may overlap in a second direction (Y-axis direction). Furthermore, the first coil portion 1152a may include a plurality of coils, which are spaced apart from each other in a first direction (X-axis direction). The first coil portion 1152a may include a 1-1 coil 1152a1 and a 1-2 coil 1152a2. The 1-1 coil 1152a1 and the 1-2 coil 1152a2 may be arranged side-by-side in the first direction (X-axis direction).

[0374] Furthermore, the second coil section 1152b may include a plurality of coils spaced apart from each other in a first direction (X-axis direction). The second coil section 1152b may include a 2-1 coil 1152b1 and a 2-2 coil 1121b2. The 2-1 coil 1152b1 and the 2-2 coil 1121b2 may be arranged side by side in the first direction (X-axis direction).

[0375] Coil 1-1 1152a1 can be configured to overlap with coil 2-1 1152b1 in the second direction (Y-axis direction). Furthermore, coil 1-2 1152a2 can be configured to overlap with coil 2-2 1152b2 in the second direction (Y-axis direction).

[0376] Furthermore, coil 1-1 (1152a1) and coil 2-2 (1152b2) can be arranged diagonally or offset from each other relative to retainer 1131 or mover 1130.

[0377] In this embodiment, coil 1-1 (1152a1) and coil 1152b2 (2-2) can generate electromagnetic forces in different directions. Furthermore, coil 1-2 (1152a2) and coil 1152b1 (2-1) can generate electromagnetic forces in different directions. Additionally, coil 1-1 (1152a1) and coil 1152a2 (1-2) can generate electromagnetic forces in the same or different directions. Furthermore, coil 2-1 (2-1) and coil 1152b2 (2-2) can generate electromagnetic forces in the same or different directions.

[0378] Furthermore, the 1-1 coil 1152a1 may include a 1-1 winding portion that rotates from one end to the other end, and the 1-2 coil 1152a2 may include a 1-2 winding portion that rotates from one end to the other end.

[0379] Furthermore, the 2-1 coil 1152b1 may include a 2-1 winding portion that rotates from one end to the other, and the 2-2 coil 1152b2 may include a 2-2 winding portion that rotates from one end to the other.

[0380] In this embodiment, each of the 1-1 winding portion and the 2-2 winding portion can be wound from one end to the other relative to the second direction in either a clockwise or counterclockwise direction. Furthermore, each of the 1-2 winding portion and the 2-1 winding portion can be wound from one end to the other relative to the second direction (Y-axis direction) in the other direction, either clockwise or counterclockwise.

[0381] For example, winding portions 1-1 and 2-2 can be wound clockwise (CW) from one end to the other relative to the second direction (Y-axis direction). Furthermore, each of winding portions 1-2 and 2-1 can be wound counterclockwise (VCW) from one end to the other relative to the second direction (Y-axis direction).

[0382] Furthermore, in the embodiments, coil 1152a1 (1-1) may include end OP1 (1-1) and the other end EP1 (1-1). Furthermore, coil 1152a2 (1-2) may include end OP2 (1-2) and the other end EP2 (1-2). Furthermore, coil 1152b1 (2-1) may include end OP3 (2-1) and the other end EP3 (2-1). Furthermore, coil 1152b2 (2-2) may include end OP2 (2-2) and the other end EP2 (2-1).

[0383] Therefore, the 1-1 winding portion can be electrically connected between end OP1 and the other end EP1 of 1-1, and can be wound from end OP1 to the other end EP1 of 1-1 in either a clockwise or counterclockwise direction relative to the second direction (Y-axis direction). Furthermore, the 1-2 winding portion can be electrically connected between end OP2 and the other end EP2 of 1-2, and can be wound from end OP2 to the other end EP2 of 1-2 in either a clockwise or counterclockwise direction relative to the second direction (Y-axis direction). Furthermore, the 2-1 winding portion can be electrically connected between end OP3 and the other end EP3 of 2-1, and can be wound from end OP3 to the other end EP3 of 2-1 in either a clockwise or counterclockwise direction relative to the second direction (Y-axis direction). Furthermore, the 2-2 winding portion can be electrically connected between the 2-2 end OP4 and the 2-2 other end EP4, and can be wound from the 2-2 end OP4 to the 2-2 other end EP4 in either a clockwise or counterclockwise direction relative to the second direction (Y-axis direction).

[0384] The following description will be based on the fact that the 1-1 winding section and the 2-2 winding section are wound clockwise (CW) and the 2-1 winding section and the 1-2 winding section are wound counterclockwise (VCW).

[0385] Furthermore, according to this embodiment, the direction of the current flowing in the 1-1 winding section can be the same as the direction of the current flowing in the 2-2 winding section relative to the second direction. Additionally, the directions of the magnetic forces generated by the first magnet and the second magnet can be opposite to each other. Therefore, the directions of the electromagnetic force generated from the 1-1 winding section and the electromagnetic force generated from the 2-2 winding section can be opposite.

[0386] Furthermore, according to this embodiment, the direction of the current flowing in the 1-2 winding section can be the same as the direction of the current flowing in the 2-1 winding section relative to the second direction. Additionally, the directions of the magnetic forces generated by the first magnet and the second magnet can be opposite to each other. Therefore, the directions of the electromagnetic force generated from the 1-2 winding section and the electromagnetic force generated from the 2-1 winding section can be opposite.

[0387] Furthermore, end OP1 (1-1) and end OP4 (2-2) can be electrically connected to each other to form a first node N1. Additionally, the other end EP1 (1-1) and the other end EP4 (2-2) can be electrically connected to each other to form a second node N2. Two closed-loop circuits can be formed relative to the first node N1 and the second node N2. In other words, the closed-loop circuit can have a structure where current can be applied to the first node N1 and the applied current can be output through the second node N2.

[0388] Furthermore, OP2 at end 1-2 and OP3 at end 2-1 can be electrically connected to each other to form a third node N3. Additionally, EP2 at the other end 1-2 and EP3 at the other end 2-1 can be electrically connected to each other to form a fourth node N4. Two closed-loop circuits can be formed relative to the third node N3 and the fourth node N4. In other words, the closed circuit can have a structure where current can be applied to the third node N3 and the applied current can be output through the fourth node N4.

[0389] Furthermore, in this embodiment, the current applied to the first node N1 and the current applied to the third node can be applied in the same direction. In other words, when the current applied to the first node N1 is positive (+), the current applied to the third node is also positive (+), and when the current applied to the first node N1 is negative (-), the current applied to the third node is also negative (-). Therefore, the electromagnetic force generated from coil 1-1 1152a1 and the electromagnetic force generated from coil 2-2 1152b2 can be in opposite directions. Furthermore, the electromagnetic force generated from coil 1-2 1152a2 and the electromagnetic force generated from coil 2-1 1152b1 can be in opposite directions.

[0390] As described above, coil 1-1 (1152a1) and coil 1152b2 (2-2) form a channel and can receive the same current to move the mover. In other words, this can be beneficial for tilt control of the mover. Similarly, coil 1-2 (1152a2) and coil 1152b1 (2-1) also form a channel and can receive the same current to move the mover. In other words, this can be beneficial for tilt control of the mover.

[0391] Furthermore, in the first camera actuator according to the embodiment, the multiple coils of the drive coil are arranged in a pattern of symmetry, particularly in the first direction (X-axis direction), thereby minimizing the effects caused by posture differences. Moreover, in the case of asymmetrical coils, since the deviation of current change compared to the degree of tilt increases, the current control for drive can be performed linearly compared to multiple asymmetrically arranged coils. In other words, control is advantageous.

[0392] Figure 21This is a view showing the first drive of the drive coil according to an embodiment, and Figure 22 This is a view showing the motion of the first driven mover.

[0393] refer to Figure 21 and 22 In the camera module according to this embodiment, for example, the first magnet and the second magnet of the first camera actuator can be located on the outer surface of the holder by a vertical magnetization method. For example, in the embodiment, the N pole and the S pole of each of the first magnet and the second magnet can be positioned facing the first coil portion and the second coil portion. For example, the N pole can be located in the third direction compared to the S pole. For example, each of the N pole and the S pole of the first magnet 1151a can be configured to correspond to the region in the first coil portion where the current flows in the X-axis direction or the opposite direction.

[0394] In this embodiment, magnetic forces DM1 and DM2 can be applied from the N pole of the first magnet in a direction opposite to the second direction (Y-axis direction), and when current DE1 flows from the 1-1 coil 1152a1 corresponding to the N pole along the first direction (X-axis direction), electromagnetic force DEM1 can act in a direction opposite to the third direction (Z-axis direction) according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule). Therefore, since the 1-1 coil 1152a1 is attached to the housing and its position is fixed, the upper part of the retainer can be moved in the third direction (Z-axis direction) by electromagnetic force DEM1. The electromagnetic forces, etc., will be described below based on the N pole of each magnet.

[0395] Furthermore, in this embodiment, when a magnetic force can be applied from the N pole of the first magnet in a direction opposite to the second direction (Y-axis direction) and current DE2 flows from the 1-2 coil 1152a2 corresponding to the N pole in a direction opposite to the first direction (X-axis direction), the electromagnetic force DEM2 can act in the Z-axis direction according to the interaction of the electromagnetic forces. At this time, since the 1-2 coil 1152a2 is fixed to the side of the housing, the lower part of the retainer can be moved in the direction opposite to the Z-axis direction by the electromagnetic force DEM2.

[0396] Furthermore, in the embodiment, when magnetic forces DM3 and DM4 can be applied from the N pole of the second magnet along the second direction (Y-axis direction) and current DE3 flows from the 2-1 coil 1152b1 corresponding to the N pole in the direction opposite to the first direction (X-axis direction), the electromagnetic force DEM3 can act in the direction opposite to the third direction (Z-axis direction) according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule). Therefore, since the 2-1 coil 1152b1 is attached to the housing and its position is fixed, the upper part of the retainer can be moved in the third direction (Z-axis direction) by the electromagnetic force DEM3.

[0397] Furthermore, in this embodiment, when magnetic forces DM3 and DM4 can be applied from the N pole of the second magnet along the second direction (Y-axis direction) and current DE4 flows from the 2-2 coil 1152b2 corresponding to the N pole along the first direction (X-axis direction), the electromagnetic force DEM4 can act in the Z-axis direction according to the interaction of electromagnetic forces. At this time, since the 2-2 coil 1152b2 is fixed to the side of the housing, the lower part of the retainer can be moved in the opposite direction to the Z-axis direction by the electromagnetic force DEM4.

[0398] Therefore, Y-axis tilt can be performed by electromagnetic forces DEM1 to DEM4. In other words, OIS can be achieved by rotating in the first direction (X-axis direction).

[0399] In an embodiment, the third magnet 1151c disposed below the retainer 1131 together with the third coil 1152c forms an electromagnetic force to cause the mover 1130 to tilt or rotate in the first direction (X-axis direction).

[0400] Specifically, the tilting guide portion 1141 can be connected to the first housing 1120 and the mover 1130 via a first magnetic body 1142 in the first housing 1120 and a second magnetic body 1143 in the mover 1130. In addition, the first protrusions PR1 can be spaced apart from each other in a first direction (X-axis direction) and supported by the first housing 1120.

[0401] Furthermore, the tilt guide 1141 can rotate or tilt about a second protrusion PR2 protruding toward the mover 1130, which is a reference axis (or rotation axis). In other words, the tilt guide 1141 can perform Y-axis tilting about the second protrusion PR2, which serves as a reference axis.

[0402] For example, the mover 1130 can tilt upwards about the second protrusion PR2, which serves as a reference axis. In other words, OIS can be achieved by rotating the mover 1130 in the X-axis direction by a first angle θ (X1→X1b (or X1a)) using electromagnetic forces DEM1 to DEM4. The first angle θ can be in the range of ±1° to ±3°. However, the invention is not limited thereto.

[0403] As described above, the optical component can move in a direction that is different from or the same as the direction in which the electromagnetic force is generated.

[0404] Figure 23 This is a view showing the second drive of the drive coil according to an embodiment, and Figure 24 This is a view showing the movement of the mover generated by the second drive.

[0405] refer to Figure 23 and 24Except as described below, the content described above in the first action may be applied in the same manner.

[0406] In this embodiment, when magnetic forces DM1 and DM2 are applied from the N pole of the first magnet in a direction opposite to the second direction (Y-axis direction) and current DE1 flows from the 1-1 coil 1152a1 corresponding to the N pole in a direction opposite to the first direction (X-axis direction), the electromagnetic force DEM1 acts in the third direction (Z-axis direction) according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule). Therefore, since the 1-1 coil 1152a1 is attached to the housing and its position is fixed, the upper part of the retainer can be moved in the direction opposite to the third direction (Z-axis direction) by the electromagnetic force DEM1.

[0407] Furthermore, in this embodiment, when magnetic forces DM1 and DM2 can be applied from the N pole of the first magnet in a direction opposite to the second direction (Y-axis direction) and current DE2 flows from the 1-2 coil 1152a2 corresponding to the N pole in the first direction (X-axis direction), the electromagnetic force DEM2 can act in a direction opposite to the Z-axis direction based on the interaction of electromagnetic forces. At this time, since the 1-2 coil 1152a2 is fixed to the side of the housing, the lower part of the retainer can move in the Z-axis direction by the electromagnetic force DEM2.

[0408] Furthermore, in the embodiment, when magnetic forces DM3 and DM4 can be applied from the N pole of the second magnet in the second direction (Y-axis direction) and current DE3 flows from the 2-1 coil 1152b1 corresponding to the N pole in the first direction (X-axis direction), the electromagnetic force DEM3 can act in the third direction (Z-axis direction) according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule). Therefore, since the 2-1 coil 1152b1 is attached to the housing and its position is fixed, the upper part of the retainer can be moved in the opposite direction to the third direction (Z-axis direction) by the electromagnetic force DEM3.

[0409] Furthermore, in this embodiment, when magnetic forces DM3 and DM4 can be applied from the N pole of the second magnet along the second direction (Y-axis direction) and current DE4 flows from the 2-2 coil 1152b2 corresponding to the N pole in the opposite direction to the first direction (X-axis direction), the electromagnetic force DEM4 can act in the Z-axis direction according to the interaction of electromagnetic forces. At this time, since the 2-2 coil 1152b2 is fixed to the side of the housing, the lower part of the retainer can move in the Z-axis direction by the electromagnetic force DEM4.

[0410] Therefore, Y-axis tilt can be performed by electromagnetic forces DEM1 to DEM4. In other words, OIS can be achieved by rotating in the first direction (X-axis direction).

[0411] In an embodiment, the third magnet 1151c disposed below the retainer 1131 together with the third coil 1152c forms an electromagnetic force to cause the mover 1130 to tilt or rotate in the first direction (X-axis direction).

[0412] The tilting guide portion 1141 can be connected to the first housing 1120 and the mover 1130 via the first magnetic body 1142 in the first housing 1120 and the second magnetic body 1143 in the mover 1130. In addition, the first protrusions PR1 can be spaced apart from each other in the first direction (X-axis direction) and supported by the first housing 1120.

[0413] Furthermore, the tilt guide 1141 can rotate or tilt about a second protrusion PR2 protruding toward the mover 1130, which is a reference axis (or rotation axis). In other words, the tilt guide 1141 can perform Y-axis tilting about the second protrusion PR2, which serves as a reference axis.

[0414] For example, the mover 1130 can tilt downwards about the second protrusion PR2, which serves as a reference axis. In other words, OIS can be achieved by rotating the mover 1130 in the X-axis direction by a first angle θ (X1→X1a (or X1b)) through electromagnetic forces DEM1 to DEM4. The first angle θ can be in the range of ±1° to ±3°. However, the invention is not limited thereto. Therefore, the mover can tilt vertically through a first action and a second action.

[0415] Figure 25 This is a view showing the third drive of the drive coil according to this embodiment, and Figure 26 This is a view showing the motion of the mover generated by the third drive.

[0416] refer to Figure 25 and 26 Except as described below, the content described above in the first action may be applied in the same manner.

[0417] In this embodiment, when magnetic forces DM1 and DM2 are applied from the N pole of the first magnet in a direction opposite to the second direction (Y-axis direction) and current DE1 flows from the 1-1 coil 1152a1 corresponding to the N pole in a direction opposite to the first direction (X-axis direction), the electromagnetic force DEM1 acts in the third direction (Z-axis direction) according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule). Therefore, since the 1-1 coil 1152a1 is attached to the housing and its position is fixed, the upper part of the retainer can be moved in the direction opposite to the third direction (Z-axis direction) by the electromagnetic force DEM1.

[0418] Furthermore, in this embodiment, when magnetic forces DM1 and DM2 can be applied from the N pole of the first magnet in a direction opposite to the second direction (Y-axis direction) and current DE2 flows from the 1-2 coil 1152a2 corresponding to the N pole in a direction opposite to the first direction (X-axis direction), the electromagnetic force DEM2 can act in the Z-axis direction according to the interaction of electromagnetic forces. At this time, since the 1-2 coil 1152a2 is fixed to the side of the housing, the lower part of the retainer can be moved in the direction opposite to the Z-axis direction by the electromagnetic force DEM2.

[0419] Furthermore, in the embodiment, when magnetic forces DM3 and DM4 can be applied from the N pole of the second magnet in the second direction (Y-axis direction) and current DE3 flows from the 2-1 coil 1152b1 corresponding to the N pole in the direction opposite to the first direction (X-axis direction), the electromagnetic force DEM3 can act in the direction opposite to the third direction (Z-axis direction) according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule). Therefore, since the 2-1 coil 1152b1 is attached to the housing and its position is fixed, the upper part of the retainer can be moved in the third direction (Z-axis direction) by the electromagnetic force DEM3.

[0420] Furthermore, in this embodiment, when magnetic forces DM3 and DM4 can be applied from the N pole of the second magnet in the second direction (Y-axis direction) and current DE4 flows from the 2-2 coil 1152b2 corresponding to the N pole in the opposite direction to the first direction (X-axis direction), electromagnetic force DEM4 can act in the Z-axis direction according to the interaction of electromagnetic forces. At this time, since the 2-2 coil 1152b2 is fixed to the side of the housing, the lower part of the retainer can be moved in the Z-axis direction by electromagnetic force DEM4.

[0421] Therefore, X-axis tilt can be performed by electromagnetic force DEMI to DEM4. In other words, OIS can be achieved by rotating in the second direction (Y-axis direction).

[0422] OIS can be achieved by tilting or rotating the mover 1130 in the Y-axis direction (or tilting it in the X-axis direction).

[0423] In an embodiment, the first magnet and the second magnet disposed in the holder 1131 can form an electromagnetic force together with the first coil portion 1152a and the second coil portion 1152b, respectively, to tilt or move the tilting guide portion and the mover 1130 in the second direction (Y-axis direction).

[0424] The tilting guide 1141 can rotate or tilt (X-axis tilt) around the first protrusion PR1, i.e., the reference axis (or rotation axis), in a second direction.

[0425] For example, the mover 1130 can move toward the side of the housing (particularly toward the side of the first housing) (moving in the left-right direction). Furthermore, OIS can be achieved by rotating the mover 1130 in the Y-axis direction by a second angle θ (Y1→Y1b(Y1a)) via a third action. The second angle θ can be in the range of ±1° to ±3°. However, the invention is not limited thereto.

[0426] Figure 27 This is a view showing the fourth drive of the drive coil according to an embodiment, and Figure 28 This is a view showing the motion of the mover via the fourth drive.

[0427] refer to Figure 27 and 28 Except as described below, the content described above in the first action may be applied in the same manner.

[0428] In this embodiment, when magnetic forces DM1 and DM2 are applied from the N pole of the first magnet in a direction opposite to the second direction (Y-axis direction) and current DE1 flows from the 1-1 coil 1152a1 corresponding to the N pole in the first direction (X-axis direction), the electromagnetic force DEM1 acts in a direction opposite to the third direction (Z-axis direction) according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule). Therefore, since the 1-1 coil 1152a1 is attached to the housing and its position is fixed, the upper part of the retainer can be moved in the third direction (Z-axis direction) by the electromagnetic force DEM1.

[0429] Furthermore, in this embodiment, when magnetic forces DM1 and DM2 are applied from the N pole of the first magnet in a direction opposite to the second direction (Y-axis direction) and current DE2 flows from the 1-2 coil 1152a2 corresponding to the N pole in the first direction (X-axis direction), the electromagnetic force DEM2 can act in a direction opposite to the Z-axis direction based on the interaction of electromagnetic forces. At this time, since the 1-2 coil 1152a2 is fixed to the side of the housing, the lower part of the retainer can be moved in a third direction (Z-axis direction) by the electromagnetic force DEM2.

[0430] Furthermore, in the embodiment, when magnetic forces DM3 and DM4 can be applied from the N pole of the second magnet in the second direction (Y-axis direction), and current DE3 flows from the 2-1 coil 1152b1 corresponding to the N pole in the first direction (X-axis direction), the electromagnetic force DEM3 can act in the third direction (Z-axis direction) according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule). Therefore, since the 2-1 coil 1152b1 is attached to the housing and its position is fixed, the upper part of the retainer can be moved in the opposite direction to the third direction (Z-axis direction) by the electromagnetic force DEM3.

[0431] Furthermore, in the embodiment, when magnetic forces DM3 and DM4 can be applied from the N pole of the second magnet in the second direction (Y-axis direction) and current DE4 flows from the 2-2 coil 1152b2 corresponding to the N pole in the first direction (X-axis direction), the electromagnetic force DEM4 can act in the third direction (Z-axis direction) according to the interaction of the electromagnetic forces. At this time, since the 2-2 coil 1152b2 is in a state of being fixed to the side of the housing, the lower part of the retainer can be moved in the opposite direction to the third direction (Z-axis direction) by the electromagnetic force DEM4.

[0432] Therefore, X-axis tilt can be performed using electromagnetic forces DEM1 to DEM4. In other words, OIS can be achieved by rotating in the second direction (Y-axis direction).

[0433] OIS can be achieved by tilting or rotating the mover 1130 in the Y-axis direction (or tilting it in the X-axis direction).

[0434] In an embodiment, the first magnet and the second magnet disposed in the holder 113 can form an electromagnetic force together with the first coil portion 1152a and the second coil portion 1152b, respectively, so as to tilt or move the tilt guide portion and the mover 1130 in the second direction (Y-axis direction).

[0435] The tilting guide 1141 can rotate or tilt in a second direction (X-axis tilt) about the first protrusion PR1, which serves as a reference axis (or rotation axis).

[0436] For example, the mover 1130 can move toward the side of the housing (particularly toward the side of the second housing) (moving in the left-right direction). Furthermore, OIS can be achieved by rotating the mover 1130 in the Y-axis direction (Y1→Y1a(Y1b)) by a third action. The second angle θ can be in the range of ±1° to ±3°. However, the invention is not limited thereto.

[0437] Figure 29 This is a view showing the fifth drive of the drive coil according to an embodiment, and Figure 30 This is a view showing the sixth drive of the drive coil according to an embodiment.

[0438] refer to Figure 29 In this embodiment, when a magnetic force DM2 is applied from the N pole of the first magnet in a direction opposite to the second direction (Y-axis direction) and a current DE2 flows from the 1-2 coil 1152a2 corresponding to the N pole in a direction opposite to the first direction (X-axis direction), the electromagnetic force DEM2 can act in the Z-axis direction according to the interaction of electromagnetic forces. At this time, since the 1-2 coil 1152a2 is fixed to the side of the housing, the lower part of the retainer can be moved in a direction opposite to the third direction (Z-axis direction) by the electromagnetic force DEM2.

[0439] Furthermore, in the embodiment, when a magnetic force DM3 can be applied from the N pole of the second magnet in the second direction (Y-axis direction) and a current DE3 flows from the 2-1 coil 1152b1 corresponding to the N pole in the direction opposite to the first direction (X-axis direction), the electromagnetic force DEM3 can act in the direction opposite to the third direction (Z-axis direction) according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule). Therefore, since the 2-1 coil 1152b1 is attached to the housing and its position is fixed, the upper part of the retainer can be moved in the third direction (Z-axis direction) by the electromagnetic force DEM3.

[0440] Therefore, Y-axis tilt can be performed by electromagnetic forces DEM2 and DEM3. In other words, OIS can be achieved by rotating in the first and second directions (diagonal rotation). Conversely, diagonal tilt can be performed more easily.

[0441] refer to Figure 30 In this embodiment, when a magnetic force DM1 is applied from the N pole of the first magnet in a direction opposite to the second direction (Y-axis direction) and a current DE1 flows from the 1-1 coil 1152a1 corresponding to the N pole in a first direction (X-axis direction), the electromagnetic force DEM1 acts in a direction opposite to the third direction (Z-axis direction) according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule). Therefore, since the 1-1 coil 1152a1 is attached to the housing and its position is fixed, the upper part of the retainer can be moved in the third direction (Z-axis direction) by the electromagnetic force DEM1.

[0442] Furthermore, in one embodiment, when a magnetic force DM4 can be applied from the N pole of the second magnet in the second direction (Y-axis direction) and a current DE4 flows from the 2-2 coil 1152b2 corresponding to the N pole in the first direction (X-axis direction), the electromagnetic force DEM4 can act in the third direction (Z-axis direction) according to the interaction of the electromagnetic forces. At this time, since the 2-2 coil 1152b2 is fixed to the side of the housing, the lower part of the retainer can be moved in the opposite direction to the third direction (Z-axis direction) by the electromagnetic force DEM4.

[0443] The mover can move along the first axis, along the second axis, or along both the first and second axes through the first to sixth actions described above.

[0444] Furthermore, the description of the first coil section and the second coil section, as in the first driving section according to another embodiment, can also be applied in the same manner to the first driving section according to this embodiment. In other words, according to Figure 5The first camera actuator of the illustrated embodiment may also include a first coil section having coils 1-1 and 1-2, and a second coil section having coils 2-1 and 2-2. Furthermore, refer to... Figures 19 to 30 The description of the driver can also be applied in the same manner according to the embodiments (see Figure 4 and 5 The first camera actuator.

[0445] Figure 31 This is a perspective view of the second camera actuator according to an embodiment. Figure 32 This is an exploded perspective view of the second camera actuator according to an embodiment. Figure 33 It is along Figure 31 The sectional view taken by line D-D' in the middle. Figure 34 It is along Figure 31 The sectional view taken by line E-E' in the middle.

[0446] refer to Figures 31 to 34 The second camera actuator 1200 according to an embodiment may include a lens portion 1220, a second housing 1230, a second drive portion 1250, a base portion (not shown), and a second plate portion 1270. Furthermore, the second camera actuator 1200 may further include a second shield (not shown), an elastic portion (not shown), and an adhesive member (not shown). Additionally, the second camera actuator 1200 according to this embodiment may further include an image sensor IS.

[0447] The second shield (not shown) may be located in a region of the second camera actuator 1200 (e.g., the outermost part) and may be configured to surround the components described below (lens portion 1220, second housing 1230, elastic portion (not shown), second drive portion 1250, base portion (not shown), second plate portion 1270, and image sensor (IS)).

[0448] The second shield (not shown) can block or reduce electromagnetic waves generated from the outside. Therefore, the occurrence of malfunctions in the second drive unit 1250 can be reduced.

[0449] The lens unit 1220 can be located within a second shield (not shown). The lens unit 1220 can move in the third direction (Z-axis direction). Therefore, the AF function described above can be performed.

[0450] Specifically, the lens section 1220 may include a lens assembly 1221 and a spool 1222.

[0451] Lens assembly 1221 may include one or more lenses. Furthermore, multiple lens assemblies 1221 may exist, but the following description will be based on one lens assembly.

[0452] The lens assembly 1221 can be coupled to the bobbin 1222 and can be moved in the third direction (Z-axis direction) by the electromagnetic force generated from the fourth magnet 1252a and the second magnet 1252b coupled to the bobbin 1222.

[0453] The spool 1222 may include an open area surrounding the lens assembly 1221. Furthermore, the spool 1222 can be attached to the lens assembly 1221 by various methods. Additionally, the spool 1222 may include grooves in its side surface, through which it can be attached to the fourth magnet 1252a and the second magnet 1252b. Adhesive components or the like can be applied to the grooves.

[0454] Furthermore, the spool 1222 can be coupled with an elastic portion (not shown) at its upper end and rear end. Therefore, the spool 1222 can be supported by the elastic portion (not shown) while moving in the third direction (Z-axis direction). In other words, when the position of the spool 1222 is maintained, the spool 1222 can be held in the third direction (Z-axis direction). The elastic portion (not shown) can be formed as a leaf spring.

[0455] The second housing 1230 may be disposed between the lens portion 1220 and the second shield (not shown). Furthermore, the second housing 1230 may be configured to surround the lens portion 1220.

[0456] A hole can be formed on the side of the second housing 1230. The fourth coil 1251a and the fifth coil 1251b can be disposed in this hole. This hole can be positioned to correspond to the groove of the spool 1222 described above.

[0457] The fourth magnet 1252a can be positioned to face the fourth coil 1251a. Furthermore, the second magnet 1252b can be positioned to face the fifth coil 1251b.

[0458] The elastic portion (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 attached to the upper surface of the bobbin 1222. The second elastic member (not shown) may be attached to the lower surface of the bobbin 1222. Furthermore, the first elastic member (not shown) and the second elastic member (not shown) may be formed as the leaf spring described above. Additionally, the first elastic member (not shown) and the second elastic member (not shown) can provide elasticity for the movement of the bobbin 1222.

[0459] The second drive unit 1250 can provide driving forces F3 and F4 to move the lens unit 1220 in the third direction (Z-axis direction). The second drive unit 1250 may include a second drive coil 1251 and a second drive magnet 1252.

[0460] The lens section 1220 can be moved in the third direction (Z-axis direction) by the electromagnetic force formed between the second drive coil 1251 and the second drive magnet 1252.

[0461] The second drive coil 1251 may include a fourth coil 1251a and a fifth coil 1251b. The fourth coil 1251a and the fifth coil 1251b may be disposed in holes formed on the side of the second housing 1230. Furthermore, the fourth coil 1251a and the fifth coil 1251b may be electrically connected to the second plate portion 1270. Therefore, the fourth coil 1251a and the fifth coil 1251b can receive current, etc., through the second plate portion 1270.

[0462] The second driving magnet 1252 may include a fourth magnet 1252a and a fifth magnet 1252b. The fourth magnet 1252a and the fifth magnet 1252b may be disposed in the groove of the aforementioned spool 1222 and positioned to correspond to the fourth coil 1251a and the fifth coil 1251b.

[0463] A base portion (not shown) may be located between the lens portion 1220 and the image sensor IS. Components such as filters may be fixed to the base portion (not shown). Furthermore, the base portion (not shown) may be configured to surround the image sensor IS. With this configuration, the image sensor IS can be protected from the influence of foreign substances, thereby improving the reliability of the device.

[0464] Furthermore, the second camera actuator can be a zoom actuator or an AF actuator. For example, the second camera actuator can support one or more lenses and perform autofocus or zoom functions by moving the lenses according to control signals from a predetermined control unit.

[0465] Furthermore, the second camera actuator can be a fixed zoom or a continuous zoom. For example, the second camera actuator can provide movement of the lens assembly 1221.

[0466] Furthermore, the second camera actuator may include multiple lens assemblies. For example, at least one of a first lens assembly (not shown), a second lens assembly (not shown), a third lens assembly (not shown), and a guide pin (not shown) may be disposed in the second camera actuator. The above description is applicable to its description. Therefore, the second camera actuator can perform a high-magnification zoom function through a drive unit. For example, the first lens assembly (not shown) and the second lens assembly (not shown) may be movable lenses that move via a drive unit and a guide pin (not shown), and the third lens assembly (not shown) may be a fixed lens, but the invention is not limited thereto. For example, the third lens assembly (not shown) may perform the function of a focuser, through which light forms an image at a specific position, and the first lens assembly (not shown) may perform the function of a zoomer to re-form the image formed by the third lens assembly (not shown) as a focuser at another position. At the same time, because the distance to the subject or the image distance is greatly changed, the first lens assembly (not shown) may be in a state of large magnification change, and the first lens assembly (not shown), i.e., the zoomer, may play an important role in the focal length or magnification change of the optical system. Meanwhile, the imaging point of the image formed by the first lens assembly (not shown) (i.e., the zoom) may vary slightly depending on the location. Therefore, the second lens assembly (not shown) can perform a position compensation function for the image formed by the zoom. For example, the second lens assembly (not shown) can function as a compensator to accurately form an image at the actual location of the image sensor using the imaging point of the image formed by the first lens assembly (not shown) which is the zoom.

[0467] The image sensor IS can be located inside or outside the second camera actuator. In one embodiment, as shown, the image sensor IS can be located inside the second camera actuator. The image sensor IS can receive light and convert the received light into electrical signals. Furthermore, the image sensor IS can include multiple pixels in an array. Additionally, the image sensor IS can be located on the optical axis.

[0468] Figure 35 This is a perspective view of a mobile terminal that uses a camera module according to an embodiment.

[0469] like Figure 35 As shown, the mobile terminal 1500 of the embodiment may include a camera module 1000, a flash module 1530 and an autofocus device 1510 disposed on the rear surface of the mobile terminal.

[0470] The camera module 1000 may include image capture functionality and autofocus (AF) functionality. For example, the camera module 1000 may include an autofocus (AF) function that uses an image.

[0471] The camera module 1000 processes image frames of still or moving images obtained by the image sensor in capture mode or video recall mode.

[0472] The processed image frames can be displayed on a predetermined display and stored in memory. A camera (not shown) can also be mounted on the front surface of the main body of the mobile terminal.

[0473] For example, camera module 1000 may include a first camera module 1000A and a second camera module 1000B, and the first camera module 1000A may implement OIS and autofocus or zoom functions. Furthermore, the AF, zoom, and OIS functions may be performed by the second camera module 1000b. In this case, since the first camera module 1000A includes both the first and second camera actuators described above, the camera device or camera module can be easily miniaturized by changing the optical path.

[0474] The flash module 1530 may include a light-emitting device for emitting light therein. The flash module 1530 may be operated by the camera of the mobile terminal or by user control.

[0475] The autofocus device 1510 may include one of the packages of a surface-emitting laser device as a light-emitting part.

[0476] The autofocus device 1510 may include an autofocus function using a laser. The autofocus device 1510 can be used primarily when the autofocus function of the image using the camera module 1000 is degraded, for example, at close range of 10m or less or in dark environments.

[0477] The autofocus device 1510 may include a light-emitting part and a light-receiving part. The light-emitting part includes a vertical-cavity surface-emitting laser (VCSEL) semiconductor device, and the light-receiving part is used to convert light energy into electrical energy, such as a photodiode.

[0478] Figure 36 This is a perspective view of a vehicle using a camera module according to an embodiment of the present invention.

[0479] For example, Figure 36 This is an exterior view of a vehicle equipped with a vehicle driving assistance system, and a camera module 1000 according to an embodiment of the present invention is applied to the vehicle.

[0480] refer to Figure 36 The vehicle 700 in the embodiment may include wheels 13FL and 13FR rotated by a power source, as well as predetermined sensors. The sensors may be camera sensors 2000, but the invention is not limited thereto.

[0481] The camera sensor 2000 may be a camera sensor of the camera module 1000 according to the embodiment. In this embodiment, the vehicle 700 can acquire image information through the camera sensor 2000 for capturing images of the front or surroundings, use the image information to determine if lane lines are not recognized, and generate virtual lane lines when lane lines are not recognized.

[0482] For example, camera sensor 2000 can acquire a frontal image by taking a picture of the front of vehicle 700, and processor (not shown) can acquire image information by analyzing the objects included in the frontal image.

[0483] For example, when an object (such as a center line corresponding to lane lines, adjacent vehicles, driving obstacles, and indirect road signs, a curb, or street trees) is captured in an image captured by the camera sensor 2000, the processor can detect the object and include the detected object in the image information. At this time, the processor can further supplement the image information by acquiring distance information to the object detected by the camera sensor 2000.

[0484] Image information can be information about objects captured in the image. The camera sensor 2000 may include an image sensor and an image processing module.

[0485] The camera sensor 2000 can process still or moving images obtained by an image sensor (e.g., complementary metal-oxide-semiconductor (CMOS) or charge-coupled device (CCD)).

[0486] The image processing module can process still or moving images captured by the image sensor to extract necessary information and transmit the extracted information to the processor.

[0487] At this time, the camera sensor 2000 may include a stereo camera, which is used to improve the measurement accuracy of the object and further ensure information, such as the distance between the vehicle 700 and the object, but the invention is not limited thereto.

[0488] Although embodiments have been primarily described above, these are merely illustrative and do not limit the invention. Those skilled in the art will understand that various modifications and applications not exemplified above are possible without departing from the essential characteristics of the embodiments. For example, each component specifically shown in the embodiments can be implemented through modifications. Furthermore, differences relating to these modifications and applications should be understood to be included within the scope of this disclosure as defined in the appended claims.
